Description

  The present invention relates to a device containing a battery, for example.

  For example, in Patent Document 1, a keep relay is installed between a battery and an electronic control device that needs to cut off dark current, and when the ignition switch is not turned on for a long time, the keep relay is cut off. In addition, a control device for a vehicle power source that prevents battery from running out is disclosed.

JP200340050

  The control device for a vehicle power source disclosed in Patent Document 1 is installed as a separate device between a vehicle battery and an electronic control device installed in the vehicle. Is a technology in which the battery voltage drops due to the dark current flowing in another electronic control device, and the battery goes up.

  For example, in a device having a battery that is not a vehicle battery and having a circuit in which dark current flows in the device, when the dark current is cut off when not used for a long period of time, the above-described conventional technology is used as it is. Cannot be used. That is, since the battery and the circuit through which dark current flows are present in the same device, the overall configuration is different from the control device of Patent Document 1, and the technology for monitoring the ignition switch state and cutting off the dark current remains unchanged. It cannot be diverted.

  (1) A device including a battery, a circuit unit through which a current from the battery flows, and a housing that houses the battery and the circuit unit, and outputs a voltage based on a terminal voltage of the battery. One connector, the first connector and the second connector detachable, the circuit portion is electrically connected to the second connector, and in a state where the first connector and the second connector are connected, The current from the battery flows, and the first connector and the second connector can be attached and detached from the opening of the housing.

  The battery may be a primary battery, for example, but may be a secondary battery. The circuit unit includes, for example, a circuit having a part that stabilizes the voltage from the battery to a voltage that is output to the outside, a circuit that monitors the voltage of the battery, and a circuit that charges the secondary battery when the battery is a secondary battery, for example. It is good to have. The housing is for housing the battery and the circuit unit, and is also referred to as a container or a case. For example, the whole may be configured by combining a plurality of parts, and in particular, the portion for storing the battery may be, for example, a cylinder surrounding the periphery of the battery. The continuity is a state in which a current can flow through at least a part of the circuit unit when, for example, the first connector and the second connector are connected and power is supplied from the battery. The power cord is preferably a lead wire, for example. For example, even if the battery has a large capacity, it can be easily handled by using a lead wire having a thickness corresponding to the lead wire. In particular, it is preferable not to provide a switch for cutting off the power supply from the battery between the battery and the circuit unit. In this way, the space required for installing the switch is not necessary, and the apparatus can be downsized.

  In the present invention, by removing the first connector and the second connector, the current supply from the battery to the circuit unit is interrupted. Therefore, for example, when the device is not used, removing the first connector and the second connector reduces the amount of current that flows from the battery to the circuit section while the device is not in use and the capacity of the battery decreases. When the user actually tries to use the device, the device operates normally.

  For example, the first connector is integrated with the battery, and the second connector is connected to the circuit portion so as to be conductive. For example, even when the first connector and the second connector are removed, the first connector and the second connector are not lost or the user does not lose sight of the connector. Connection can be made easily without searching for the second connector. In addition, the user can easily visually check the connection state of whether the first connector and the second connector are connected or disconnected, and if the desired connector is not in the desired state, the connection / separation process is performed to protect the battery appropriately. / Goes into use.

  There may be one or more circuit units. For example, when the battery is a secondary battery, there are a charging circuit that charges the secondary battery, a voltage monitoring circuit that monitors the voltage of the battery, a power output circuit that supplies power to an external device, and the like. . When there are multiple circuits, the current from the battery may not flow due to the removal of the first connector and the second connector, but some of the circuits may be part of the circuit. Since it can suppress more effectively that a capacity | capacitance falls, it is preferable.

  For example, the first connector and the second connector housed in the housing may be exposed through the opening. If it does in this way, it will become easy to perform attachment or detachment work of the 1st connector and the 2nd connector. In particular, the first connector and the second connector housed in the housing are preferably exposed through the opening. The user can easily recognize that the first connector and the second connector are exposed by looking at the opening, and therefore, they can be connected or disconnected. And since the 1st connector and the 2nd connector are exposed, the user can do insertion work etc. easily.

  (2) A cover member that covers at least a part of the opening is provided, and the first connector and the second connector are outside the casing when the cover member covers at least a part of the opening. It is best not to go out. For example, the configuration in which the first connector and the second connector in the connected state are not covered by the cover member of the opening and the first connector and the second connector in the connected state cannot pass through is configured so as not to go out of the housing. Use dimensions. By covering with a cover member, for example, the first connector and the second connector in a connected state are prevented from coming out of the housing when the apparatus is used, and the user mistakenly attaches to the first connector and the second connector. It can deter touching and coming off. Further, the first connector and the second connector may be prevented from coming out of the housing in a state where the opening is not covered with the cover member, but in the state where the cover is not covered, at least the first connector and the second connector may be prevented. It is preferable that one of them can be positioned outside the housing. In this way, the cover member can be removed from the opening, and at least one connector can be positioned outside the housing in a state where the opening is not covered. For example, the attachment / detachment work can be facilitated. As a configuration that can be positioned outside the housing, for example, the length of the wire other than the wiring pattern connected to the connector such as the power cord is lengthened, and the first connector and the second connector are placed outside the housing. It should be positioned. In this way, for example, the user can easily perform the attaching / detaching work with the first connector or the second connector positioned outside the housing, and after the attaching / detaching work, the first connector and the second connector Can be stored in the housing.

  The cover member covers at least a part of the opening, but it is more preferable to cover the entire opening. By covering the whole area, for example, dust, dust, or other foreign matter can be prevented from entering the housing, or the opening can be beautifully closed to improve the appearance.

  In the embodiment, the cover member is formed integrally with the housing. However, the cover member may be formed as a separate member and attached to and detached from the housing. The case integrated with the housing as in the embodiment is preferable because the cover member is not lost. For example, if the cover member is a separate member, the user attaches and detaches the connector with the cover member removed from the housing in order to perform the attachment and detachment work of the connector, and then attaches the removed cover member to the opening. There is a possibility of losing or losing sight when removed and placed around. In particular, the cover member may be sized according to the size and shape of the opening. In this way, the cover member tends to be small and easily lost. Further, as in the embodiment, the apparatus is preferably used for in-vehicle use, and as such an installation position of the in-vehicle apparatus, for example, it may be arranged below the floor in the vehicle interior. In such a place where the apparatus is installed at a lower position where it is difficult to attach and detach the connector, the user concentrates on the attachment and detachment of the connector, so that the cover member temporarily placed in the surrounding or other places You may not be able to find it. Further, for example, if the size of the cover member is reduced along with the size of the opening, the work of attaching and detaching the housing of the cover member which is a separate member becomes complicated. Is preferably configured.

  (3) The opening may be configured to have a size that allows a human finger to enter and allows the first connector and the second connector to be attached and detached. In such a case, the user can attach and detach the first connector and the second connector with a finger without using, for example, a special jig or tool. Therefore, for example, when you do not plan to use the device for a long period of time, you can easily and easily disconnect the first connector and the second connector, and the battery can be consumed when the device is not used. It can be suppressed. On the other hand, if it is not easy and easy to attach and detach, for example, if the period that is not expected to be used is not so long, it is cumbersome for the user to remove the first connector and the second connector, and hesitate to remove it There is a possibility to leave. For example, if the user notices due to repetition of such a situation, there is a possibility that the remaining capacity of the battery is unnecessarily reduced. Since the first connector and the second connector can be attached and detached easily and easily, for example, it is easy for the user to easily remove the first connector and the second connector, and the occurrence of such a situation can be suppressed as much as possible. .

  The housing may be configured from a single surface, but may include a plurality of surfaces. In order to allow the human fingers to enter the opening, for example, there is a case in which one surface of a housing having a plurality of surfaces is greatly opened or three-dimensionally opened. The three-dimensionally opening structure may be a structure that allows insertion of fingers from different directions, for example, and in particular, by opening three-dimensionally as in the embodiment, even if the opening area of one surface is small. Since fingers can be inserted from different directions, the first connector and the second connector can be efficiently attached and detached.

  (4) The circuit unit is provided on the substrate, and the second connector is directly connected to a portion that can be exposed to the outside through the opening of the substrate having a wiring pattern that is electrically connected to the circuit unit. It is good to make it. In the embodiment, the same board as the board on which the circuit unit is mounted and the second connector is connected, but different boards may be used. The same substrate may be simpler in configuration and easier to install in the housing.

  In this case, since the second connector is fixed to the substrate, the user can easily hold the first connector, and the user can easily remove the first connector and the second connector to protect the battery. So good. Moreover, the direction of the second connector is specified by fixing the second connector to the substrate. Therefore, for example, if the second connector is directed so that it can be inserted from the opening direction, the connector can be easily attached and detached, and the user can easily connect the first connector and the second connector when the device is not used, for example. It is good because it can be customary to remove the connector. In particular, it is preferable that the direction of insertion / removal of the first connector be in the direction along the plane of the board, since the first connector only needs to be moved along the board when the connector is attached / detached. Further, when the first connector is moved while being in contact with the board and is configured to be attached to and detached from the second connector, the user can attach / detach the connector by moving the board while pressing the first connector against the board, for example. Can be done. In this case, if the opening described in (3) is provided in a three-dimensional manner, and the opening surface includes at least a surface facing the substrate, workability when pressing the first connector against the substrate, For example, it is preferable because a space for moving a finger can be secured.

  In particular, the substrate is preferably fixed so as not to move when the first connector and the second connector are attached and detached, and particularly preferably fixed to the housing.

  (5) The circuit portions other than the wiring pattern may not be exposed from the opening. In this way, when the first connector and the second connector are attached and detached, it is possible to suppress as much as possible that the user accidentally touches the parts / elements of the circuit section and foreign matters are mixed in. good.

  (6) The power cord is routed along the side surface of the battery and is disposed in a space between the side surface of the battery and the inner side surface of the housing along the side surface of the battery. Good. For example, in the case of a cylindrical battery, the side surface of the battery is a peripheral surface. For example, in the case of an assembled battery in which a plurality of unit cells are combined, the side surface of the unit cell located outside or a surface where no electrode appears. . In this way, since the power cord is along the side of the battery, the space for drawing the power cord does not swell so much outside the battery. The space between the side surface of the battery around which the power cord is routed and the inner side surface of the housing along the side surface need only have a gap for arranging the power cord, and may be narrow. Therefore, the space in the housing can be reduced. For example, the space for housing the battery in the housing can be made close to the outer shape of the battery to make the entire apparatus compact.

  (7) The opening may be provided on an end side of the casing on a space side in which the circuit unit of the casing is accommodated. By providing it at the end of the housing, a work space including the external space of the housing can be secured when the user attaches / detaches the first connector and the second connector. Further, since the first connector and the second connector are disposed not on the side where the battery is stored but on the side where the circuit unit is stored, it is easy to secure the storage space. In particular, in the case of making an opening that allows a human finger to enter as in the invention described in (3), by providing an opening at the end of the housing, for example, as in the embodiment, the opening is three-dimensional. Then, the space inside and outside the housing is connected, and a large work space can be secured, which is preferable. Further, when combined with the invention described in (6), the end portion of the end casing is preferably provided on the same side connected to the inner surface of the casing in which the power cord is arranged.

  (8) The housing includes a case main body having a storage portion for storing the battery, and a first case covering one surface of the case main body, and the circuit is included in a space surrounded by the case main body and the first case. A part may be mounted, and the one surface of the case main body may include a partition wall that partitions the space in which the storage part and the circuit part are mounted. One surface of the case body corresponds to the front surface 11a in the embodiment. The case body may be configured such that the battery is sandwiched between a plurality of parts such as upper and lower parts, for example. For example, it is preferable to use a cylindrical one because the battery can be securely stored and held. For example, a part that surrounds the entire circumference of the battery is preferably integrated, for example, as in the embodiment, for example, a shape in which the battery is replaceable and has an outlet for taking out from the case body. It would be good if

  A battery housing part and a space in which the circuit part is mounted are separated by a partition wall. Some batteries, for example, have an output that decreases as the ambient temperature rises, and some circuits have elements or parts that generate heat when energized. Therefore, for example, even when the device is in use, even if the current from the battery flows into the circuit unit and generates heat, and the temperature of the space around the circuit unit rises, the space and the battery storage unit are separated by a partition wall. For this reason, the temperature rise is suppressed without being immediately transmitted to the storage section, and the battery capacity can be prevented from being lowered. In addition, for example, it is more preferable to arrange a cooling member such as a heat sink on the partition wall so as to suppress heat dissipation or partial diffusion of heat due to heat diffusion.

  (9) An opening for an interface with the outside and the opening may be provided on a surface of the first case that faces the storage portion. The surface facing the storage portion corresponds to the front wall portion 12a of the front case 12 in the embodiment. Examples of the interface with the outside include an interface for connecting to an external device / apparatus, a man-machine interface for a user, and the like. In the embodiment, an interface connected to various devices / apparatuses corresponds to an output terminal or an input terminal of power. In the embodiment, the man-machine interface corresponds to a light emitting unit such as an LED, a setting switch, or the like. Since the interface with the outside and the opening are arranged on the same surface, user convenience is improved.

  (10) The partition wall is formed at a position recessed from the front end on the one surface side of the case body, and a circuit is formed in a front end space surrounded by the partition wall and a peripheral wall portion protruding on the one surface side of the case body. It is preferable that the substrate of the portion is mounted and the surface of the substrate of the circuit portion is positioned near the tip of the peripheral wall portion. The one surface side corresponds to the front surface 11a side in the embodiment. In this way, the substrate can be stored in the distal end side space, and the substrate may be contained in the distal end side space in a state where the first case is removed and one surface of the case main body is opened. In addition, since the surface of the substrate is positioned near the tip of the peripheral wall portion, the distance from the surface of the substrate and the surface facing the storage portion of the first case can be reduced, for example. . Then, for example, when various external interfaces are mounted on the surface of the board, even when a member having a low interface height is used, the interface is positioned in the vicinity of the surface facing the housing portion of the first case. I can do it. In particular, when the combination with (4) is performed, when the second connector is attached to the substrate by the surface of the substrate being located near the tip of the peripheral wall, the direction of insertion / removal to the second connector is temporarily Even in the direction along the surface of the substrate, the first connector can be easily inserted and removed.

  (11) A region where the light emitting unit is provided on a surface of the first case facing the storage unit, and the light emitting unit is provided on a surface of the first case facing the storage unit is the storage of the first case. It is good to be located in the said partition wall side rather than the reference | standard position of the surface which opposes a part. For example, the light emitting unit may guide light emitted from a light emitting source such as an LED attached to a substrate to the light emitting unit and emit the light to the outside. By bringing the region where the light emitting unit is provided closer to the partition wall side, the light guide path that guides light from the light source to the light emitting unit can be shortened.

  (12) A setting switch can be operated from an opening portion provided on a surface facing the storage portion of the first case, and a region where the opening portion is provided on a surface facing the storage portion of the first case is: The region of the first case that is positioned closer to the partition wall than the reference position of the surface that faces the storage portion and that provides the opening portion is configured to reach a surface that intersects the surface that faces the storage portion. Good. In this way, the operation surface of the setting switch is located deeper on the partition wall side than the reference position, so that it is possible to prevent the setting switch from being accidentally touched and changed as much as possible. Can do. On the other hand, if only the setting switch portion is formed at a position deeper on the partition wall side than the reference position, it becomes complicated to perform a switch operation by placing a finger or the like in the vicinity of the setting switch when performing a normal setting. Since the region where the setting switch is provided reaches the surface intersecting with the surface facing the storage portion in a state where the setting switch is positioned on the partition wall side, for example, the user places the fingertip near the operation surface of the setting switch. In this state, the finger can be positioned so as to escape from the intersecting surface side to the outside of the first case, and the setting operation can be easily performed. For example, as in the embodiment, if the surface to be reached is on the upper side with the housing placed, the user can perform the setting operation with the housing placed.

  (13) The circuit unit substrate includes a plurality of substrates, and the plurality of substrates are arranged so as to overlap each other via a spacer member, and the spacer member is configured using a member having good thermal conductivity. Good. If it does in this way, a plurality of substrates can be arranged in piles maintaining a desired interval by interposing a spacer member, and further, the spacer member radiates heat or diffuses heat and becomes partially hot. It is sufficient to have a function of suppressing the above.

  (14) The circuit unit substrate includes a plurality of substrates, and the plurality of substrates are arranged so as to overlap each other via a spacer member, and a magnetic field is formed on at least one of the opposing surfaces of the plurality of substrates. A generation source may be disposed, the spacer member may be disposed so as to surround the magnetic field generation source, and the spacer member may be configured using a magnetic material. If it does in this way, magnetic shielding can be performed while exhibiting a spacer function. The perimeter may be all around the four sides or may surround the sides.

  (15) It is preferable that a circuit board other than the power cord or a member for outputting the power of the battery is not disposed in a housing portion that houses the battery in the housing. By not arranging the circuit board in the storage section, it is possible to eliminate the heat source in the storage section and to suppress the deterioration of the battery performance due to heat. Moreover, the space of a storage part can be cleared by eliminating arrangement | positioning of members other than a battery as much as possible in a storage part. For example, when external vibration or acceleration is applied to the housing, even if the vibration is large and the battery may be displaced relative to the housing, it will not be damaged by contact with the circuit board. .

  (16) The inner shape of the storage portion for storing the battery in the housing is sized according to the outer shape of the battery, and at least a part of the inner peripheral surface of the storage portion is kept in contact with the battery. It is good to do so. For example, the inner peripheral surface of the storage unit may be in direct contact with the battery, or may be in indirect contact with another member, for example. As a configuration for indirect contact, for example, a cushion may be interposed as in the embodiment. In this way, for example, the battery can be suppressed more securely, for example. Since at least a part of the contact is made, for example, it is not essential to make the inner shape of the storage portion substantially equal to the outer shape of the battery.For example, the battery is suppressed on the upper and lower surfaces of the casing in use as in the embodiment, In the left and right width direction, the length of the storage part is longer than the length of the battery, and a space may be secured between the left and right ends of the battery and the inner peripheral surface of the storage part, as in the embodiment In the case of contact indirectly through a cushion made of an elastic material, contact is made at the portion of the cushion, and contact is not made at other portions, but such a configuration is also included because part of the contact is made.

  According to the present invention, the battery can be suppressed by the storage portion, that is, the housing, and a special fastener for fixing the battery is not necessary, and the battery can be held with a simple configuration. In particular, when combined with the invention of (9), there is no circuit board in the storage part and the arrangement of members other than the battery is suppressed as much as possible, for example, the inner shape of the storage part is made substantially equal to the outer shape of the battery. It is preferable because the battery can be held as a whole.

  (17) It is preferable that an elastic material is attached to the upper inner surface of the casing in use, and the inner surface is in contact with the battery via the elastic material. The elastic material corresponds to the cushion 22 in the embodiment. The elastic material has elasticity and can hold the battery firmly. For example, even if vibration or the like is applied to the battery from the outside, the relative movement in the battery housing portion can be more reliably suppressed. By disposing the elastic material on the upper side, the weight of the battery is not added to the elastic material, and the elastic material can be prevented from sagging with respect to long-term use and can be held for a long time. Further, for example, the housing is preferably made of a material that is bent or has elasticity. If it does in this way, even if the external dimension of a battery is a little large, a housing | casing bends and storage of a battery can be accept | permitted. The housing may be manufactured from, for example, plastic or resin.

  (18) The battery can be taken out from the housing, and a switch for turning ON / OFF the power supply from the battery is preferably not provided. In the case of a battery that can be removed from the housing, it is necessary to release the connection with the circuit unit in the housing when removing the battery, and in order to easily release the connection, the battery in a form in which a connector is connected to the power cord Should be used. By using the connector that is originally required for this purpose as the first connector for cutting off the current flowing from the battery to the circuit when the device is not used, it is possible to eliminate the need for a switch. Miniaturization can be achieved with a simple configuration.

  (19) It is preferable to remove the first connector and the second connector at the time of shipment. Thus, by removing both connectors at the time of shipment, the power consumption of the battery can be suppressed until the user goes to hand. For example, if the first connector is integrated with the battery and the second connector is connected to the circuit portion so that the circuit is connected, the user can acquire the device even when the first connector and the second connector are removed. The first connector and the second connector will not be lost until this time, and the user who has acquired this device can use the device by connecting the first connector and the second connector.

  (20) A power output function for supplying the battery power to an external device may be provided.

  (21) The battery is a secondary battery, and includes a charging circuit that receives power supplied from an external power source and charges the secondary battery, and the first connector and the second connector are not connected, It is preferable that power can be supplied to the external device based on power supply from the external power source. In particular, even when the first connector and the second connector are not connected, it is preferable to supply power to an external device based on power supply from an external power source. If it does in this way, even if it forgets to connect with removing the 1st connector and the 2nd connector in use, it is good because electric power can be supplied to an external device. In addition, for example, the charging circuit for the secondary battery has a protection circuit, and there is a battery that cannot be charged when the voltage of the secondary battery lowers the reference value, but when not in use, remove the first connector and the second connector. Since the voltage drop of the secondary battery is suppressed as much as possible, it is possible to suppress a situation where charging cannot be performed.

  The above inventions (1) to (21) can be arbitrarily combined. For example, not all or a part of (1) may be provided, but other configurations (2) to (22) may be provided. However, in particular, it is preferable to have the configuration (1) and the arbitrary configurations and combinations described in (2) to (21). Arbitrary components of the inventions (1) to (21) may be extracted and combined with other components.

  According to the present invention, for example, when the battery is not used for a long period of time, the voltage between the terminals of the battery is prevented from greatly dropping, and when the apparatus is to be used, power can be supplied from the battery and normal operation can be performed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. These drawings are used to explain technical features that can be adopted by the present invention. The configuration, shape, and the like of the device described are merely illustrative examples, and the present invention is not construed as being limited thereto, and is based on the knowledge of those skilled in the art without departing from the scope of the present invention. Various changes, modifications, and improvements can be added.

  A preferred embodiment of the apparatus of the present invention will be described based on an example applied to a power supply apparatus. The power supply device 10 of this embodiment includes a battery 1, a circuit unit 2, and a housing 3 that stores them. The power supply device 10 is connected to a device outside the power supply device 10 such as an electric device or an electronic device, and can supply power to the device from the battery 1 built in the housing 3. The power can be supplied, for example, when the power supply of the device is ON, the power supply device 10 supplies power to the device from the battery 1 or the like.

  The battery 1 is a rechargeable secondary battery, for example. In the present embodiment, the secondary battery uses a nickel metal hydride battery. As shown in FIG. 34 and subsequent figures, for example, a plurality of cylindrical unit cells 4 are used, and these unit cells 4 are arranged in a single row horizontally in the radial direction. Assume that the assembled array of S arrays is an assembled battery packed with the heat-shrinkable tube 5. Since it is S array, it becomes a flat shape. Furthermore, as will be described later, the device to be supplied with power by the power supply device 10 of the present embodiment is, for example, an in-vehicle device. In accordance with the output voltage of the vehicle battery 12V, twelve 1.2V unit cells 4 are used, and the voltage between the terminals of the battery 1 is 12V at the time of full charge. The battery 1 has a power cord 6, and a first connector 7 is provided at the tip of the power cord 6. The terminal voltage of the battery 1 appears at the first connector 7. The first connector 7 is a male connector.

  The circuit unit 2 includes, for example, a charging circuit that charges the battery 1 that is a secondary battery, a voltage monitoring circuit that monitors the voltage of the battery 1, a power output circuit that supplies power to an external device, and the like. The charging circuit may be configured using, for example, a management IC. The management IC has a function of monitoring the voltage of the battery 1 and charging when the voltage drops. Further, when the voltage of the battery 1 becomes equal to or lower than the reference value, the management IC cannot recognize the presence of the battery 1 and does not execute the charging process even when a chargeable voltage is applied from the outside. The voltage monitoring circuit includes, for example, a microcomputer, and the voltage between the terminals of the battery 1 is biased by a resistor, and is detected to 5 V or less that can be detected by the microcomputer. Since the microcomputer is used in this way, a circuit for generating and supplying a power supply voltage (for example, 5 V) for driving the microcomputer is provided. The circuit for the power supply voltage of such a microcomputer is provided with, for example, a 5V regulator and stably outputs 5V. Even when the power of the device is OFF and no power is supplied to the device, the leakage current in the management IC and 5V regulator and the current that flows through the bias resistor for voltage monitoring are generated. The remaining capacity of the battery 1 gradually decreases.

  The housing 3 has a flat shape corresponding to the outer shape of the battery 1. The housing 3 includes a case main body 11, a front case 12, and a rear case 13. The case main body 11 is formed in a cylindrical shape, and the front surface 11a and the rear surface 11b in a state where the power supply device 10 is installed are respectively opened (see FIGS. 20 and 31). The front case 12 is mounted on the front surface 11a side of the case body 11 and closes the opening of the front surface 11a. The rear case 13 is mounted on the rear surface 11b side of the case body 11 and closes the opening of the rear surface 11b.

  The front side in the case body 11 and the space surrounded by the front case 12 constitute a circuit mounting portion 15 for mounting the circuit portion 2. Further, the space surrounded by the rear side of the case body 11 and the rear case 13 constitutes a storage unit 16 that stores the battery (see FIGS. 32, 33, etc.).

  A cover member 17 is provided on one end side of the front case 12 in the longitudinal direction. One end side where the cover member 17 is provided is the left side in the present embodiment. The cover member 17 is formed integrally with the front case 12 and rotates forward and backward about the hinge portion 18 to open and close.

  A cover member 17 covers the opening 3 a provided in the housing 3. The opening 3a is a portion that is opened and opened when the cover member 17 is opened. In the present embodiment, the opening 3a includes a plurality of front surfaces, an upper surface, a lower surface, and a left side surface in the installed state of the power supply device. A three-dimensional opening 3a is formed on the surface.

  The first connector 7 exists in an internal space surrounded by the cover member 17 when the cover member 17 is closed. As shown in FIG. 1B and the like, when the cover member 17 is opened, the first connector 7 exists in the opened space and is exposed to the outside. A first connector 7 and a detachable second connector 8 are arranged in an internal space surrounded by the closed cover member 17.

  When the cover member 17 is opened, the first connector 7 and the second connector 8 are present in the three-dimensional opening 3a surrounded by the cover member 17, and the opening 3a is opened, so that the user or the like Is configured such that a finger can be inserted and disposed in the opening 3a, and the first connector 7 and the second connector 8 can be attached and detached.

  The circuit unit 2 is electrically connected to the second connector 8. Therefore, as shown in FIG. 1 (d), in the state where the first connector 7 and the second connector 8 are connected, even when the power of the device is OFF, the current from the battery 1 flows to the circuit unit 2, and the circuit Electric power is consumed in part 2. Therefore, when such a state continues in a state where the battery 1 is not charged, the remaining capacity of the battery 1 decreases and the voltage between the terminals of the battery 1 drops. As a result, if the time until the next use of the device becomes long, the remaining capacity of the battery 1 may be insufficient when the device is used, and normal operation may not be performed. The normal operation cannot be performed here, for example, because a voltage drop is large and a voltage necessary for operating the device cannot be obtained, and the device cannot be driven. Further, in the present embodiment, since the battery 1 is a secondary battery, normal operation cannot be performed. For example, the voltage between the terminals of the battery 1 is below a reference value, and the management IC It is impossible to recognize the presence and charge.

  On the other hand, as shown in FIG. 1C, when the first connector 7 and the second connector 8 are removed, the current supply from the battery 1 to the circuit unit 2 is interrupted. Therefore, for example, when a device connected to the power supply device is not used, if the cover member 17 is opened and the first connector 7 and the second connector 8 are removed, a current flows through the circuit unit 2 while the device is not used. The amount by which the capacity of the battery 1 is reduced is reduced. Therefore, when trying to use a device next time, the possibility that the remaining capacity of the battery 1 is insufficient and normal operation cannot be performed is suppressed as much as possible. Therefore, for example, when it can be predicted that the state of not using the device will continue, the user may open the cover member 17 and perform the work of removing the first connector 7 and the second connector 8. By doing so, it is possible to suppress the consumption of the battery 1 as much as possible, and to prevent the normal operation from being performed due to a decrease in the voltage of the battery 1 when the device is used next time.

  In the present embodiment, the first connector 7 and the second connector 8 are configured not to come out of the housing in a state where the opening 3 a is covered with the cover member 17. By covering with the cover member, for example, the first connector 7 and the second connector 8 in a connected state are prevented from coming out of the housing 3 when the power supply device 10 is used, and the user accidentally 7 and the second connector 8 are prevented from coming off.

  In the present embodiment, since the cover member 17 covers the entire opening 3a, for example, dust, dust or other foreign matters can be prevented from entering the housing 3, or the opening 3a can be neatly blocked. It looks good because it looks good.

  In this embodiment, the opening 3a is formed on a plurality of adjacent surfaces, and in the state where the cover member 17 is opened, a human finger enters the space of the opening 3a, and the first connector 7 and the second connector 8 For example, the first connector 7 and the second connector 8 can be attached and detached without using a special jig or tool. Therefore, for example, when the device is not used for a long time or a long time, the user can easily and easily remove the first connector 7 and the second connector 8 and does not use the power supply device 10. This is because the consumption of the battery 1 can be suppressed as much as possible.

  The power supply device 10 includes an input terminal portion 20 and an output terminal portion 21 on the front surface of the front case 12. The input terminal unit 20 receives power supply in cooperation with a vehicle battery. The output terminal unit 21 is linked to a device and supplies power to the device. The charging circuit of the circuit unit 2 receives power supplied from the vehicle battery and charges the battery 1. For example, when the power output circuit of the circuit unit 2 is supplied with power from the battery of the vehicle, the power of the battery is supplied to the device as it is, and when the power supply from the battery is not received, the battery 1 Supply power to the equipment.

[Specific configuration]
As described above, by removing the first connector 7 and the second connector 8, the power supply device 10 of the present embodiment blocks the path through which current flows from the battery 1 to the circuit unit 2, and the remaining capacity of the battery 1 is reduced. It has a function to suppress it. A more specific configuration of the power supply device 10 having such a function is as follows.

[Specific Configuration of Battery 1]
As described above, the battery 1 is composed of an assembled battery of S arrangement, and the overall shape is flat. And since the circumference | surroundings of the assembled battery are packed with the heat contraction tube 5, the external shape of the battery 1 is flat form as a whole, and the both right and left side surfaces 1a become circular arc shape. Further, one end side of the power cord 6 linked to the battery 1 is covered with the heat shrinkable tube 5, and is drawn out from the gap 5 a of the heat shrinkable tube 5. When the heat-shrinkable tube 5 located on the outer surface is arranged so as to circulate in the front-rear direction in which the electrodes of the battery 1 are arranged, for example, the open ends of the shrunk heat-shrinkable tube 5 are the left and right sides of the arc 1 of the battery 1 By setting the length of the heat-shrinkable tube 5 appropriately as the surface 1a, both edges of the heat-shrinkable tube 5 are put on the peripheral edges of the both side surfaces 1a of the battery 1, and the center of the both side surfaces 1a of the battery 1 is set. The portion is in a state where the heat shrinkable tube 5 does not exist. For example, if the heat shrinkable tube 5 whose direction of rotation is changed is arranged inside the heat shrinkable tube 5 located on the outer surface, both left and right side surfaces 1a of the battery 1 without the heat shrinkable tube 5 located on the outer surface are present. This portion is also preferable because the inner heat-shrinkable tube 5 is present and the unit cell is not exposed.

  Both end edges of the heat-shrinkable tube 5 located on the outer surface form a gap 5a, and the power cord 6 is drawn out from the gap 5a. In the present embodiment, the power cord 6 is disposed along the one end surface 1b in the front-rear direction of the battery 1 inside the heat-shrinkable tube 5, and reaches one side (for example, the left side) 1a. It is pulled out from the gap 5a between the edges. The heat-shrinkable tube 5 is shrunk so as to follow the surface shape of the battery 1 at the time of heat-shrinking, and is shrunk into a shape in which both sides are rolled up at the boundary portion between one end face 1b of the battery 1 and the side face 1a adjacent thereto. Therefore, the portion of the power cord 6 located at the boundary portion is bent toward the side surface 1 a as the heat shrinkable tube 5 is thermally contracted.

  The power cord 6 drawn out of the heat-shrinkable tube 5 is arranged along one side surface 1a of the battery 1, and the first connector 7 projects ahead of the other end surface 1c in the front-rear direction of the battery 1. To do. When the battery 1 is mounted in the storage portion 16, the other end face 1c in the front-rear direction of the battery 1 is positioned on the front case 12 side, and the power cord 6 is connected to the side face 1a of the battery 1 and its side It arrange | positions in the space between the inner surface of the housing | casing 3 which opposes the side surface 1a (FIG. 32 etc.).

  In the present embodiment, since the battery 1 has a rated output of 12V and a capacity of as large as 4000 mAh, for example, the power cord 6 is also configured using, for example, a lead wire, and the lead wire is also relatively thick, hard, and difficult to bend. Something is used. As described above, the power cord 6 is pulled out and guided toward the other end face 1c side in the front-rear direction by the heat-shrinkable tube 5 slightly. Even when the power cord 6 is arranged along the side surface 1a of the battery 1, an excessive load is not applied to the bent portion, and the portion is not damaged. Moreover, since the power cord 6 is slightly bent by the heat shrinkable tube 5 toward the other end surface 1c side in the front-rear direction of the battery 1, it can be routed as it is close to the side surface 1a.

  On the other hand, for example, when the front-rear direction of the battery 1 in the storage portion 16 is reversed and one end surface 1b side in the front-rear direction of the battery 1 is positioned on the front case side, the heat contraction tube 5 of the power cord 6 is exposed to the outside. Since the part to be pulled out is also on the front case 12 side, the distance between the two is shortened, and the cord length of the power cord 6 may be shortened. However, since the power cord 6 is pulled out toward the other end face 1c as described above, the power cord 6 is folded back 180 degrees opposite to the pulling direction. In the present embodiment, since the power cord 6 is relatively hard, it is necessary to draw it in a loop shape that bulges outward for folding, and the side surface 1a of the battery 1 and the housing 3 and the case body 11 that face the side surface 1a. Since it is necessary to make a large gap between the side surfaces and the size and shape become large, it is preferable to dispose them as in this embodiment. In addition, if it is turned back to the opposite side by 180 degrees, an excessive load may be applied to the power cord 6 and there is a possibility that the deterioration over time may be accelerated.

  Further, when the first connector 7 is attached to the second connector 8, the work is easier if the power cord 6 is longer to some extent. However, the power cord 6 needs to be stored in the housing 3 with the cover member 17 closed. If the power cord 6 is long, the cover member 17 cannot be accommodated in the closed space. Therefore, as in the embodiment, it is preferable that the power cord 6 slightly protrudes to the opening 3 a side and the first connector 7 reaches the second connector 8.

[Specific Configuration of Housing 3]
* Battery storage structure, etc. The outer shape of the housing 3 corresponds to the outer shape of the battery 1 and is a flat shape, and the left and right sides of the rectangular body are arcuate. Further, the power supply cord 6 and the circuit board other than the member for outputting the power of the battery 1 are not arranged in the storage portion 16 that stores the battery 1 in the housing 3. By not arranging the circuit board in the storage section, the heat source in the storage section 16 can be eliminated, and the performance degradation of the battery 1 due to heat can be suppressed.

  Moreover, the space of the accommodating part 16 can be made clear by eliminating arrangement | positioning of members other than a battery in the accommodating part 16 as much as possible. For example, when external vibration / acceleration is applied to the casing 3, even if the vibration or the like is large and the battery 1 may be displaced relative to the casing 3, the circuit board contacts the circuit board and is damaged. It ’s okay.

  A partition wall 14 is provided inside the case main body 11 as shown in FIGS. 32, 33, etc., in order to separate the storage portion 16 for the battery 1 in the housing 3 and the space for storing the circuit portion 2. The partition wall 14 is provided on the front surface 11 a side in the case body 11, and a larger space is formed on the rear surface 11 b side than the partition wall 14. The front side of the partition wall 14 of the case body 11 and the space surrounded by the front case 12 constitute a circuit mounting portion 15 for mounting the circuit portion 2. Further, the rear side of the partition wall 14 of the case body 11 and the space surrounded by the rear case 13 constitute a storage unit 16 that stores the battery.

  A communication hole 14 a is formed at the left end of the partition wall 14. The front and rear spaces formed across the partition wall 14 are connected, the power cord 6 is disposed so as to pass through the communication hole 14 a, and the first connector 7 is located on the front side of the partition wall 14.

  In this embodiment, the storage part 16 of the battery 1 and the space in which the circuit part 2 is mounted are partitioned by the partition wall 14. As described above, for example, the battery 1 may have an output that decreases with an increase in ambient temperature, and the circuit unit 2 may be configured to include elements and components that generate heat when energized. For example, when the power supply device 10 is used, even if the current from the battery 1 flows into the circuit unit 2 to generate heat and the temperature of the space around the circuit unit 2 rises, the space and the storage unit 16 of the battery 1 are separated from each other. 14, the temperature rise is suppressed without being transmitted immediately to the storage section 16 side, and the battery capacity reduction can be suppressed. The partition wall 14 has a communication hole 14a for passing the power cord 6 to the minimum necessary, but the others are closed. There is also a protection circuit on the battery 1 side, and charging stops when the temperature rises. Therefore, the provision of the partition wall 14 suppresses the occurrence of such a situation.

  The inner shape of the storage portion 16 that stores the battery 1 in the housing 3 is a dimensional shape corresponding to the outer shape of the battery 1. And at least one part of the inner peripheral surface of the accommodating part 16 contacts the battery 1, and it is made to suppress. In the present embodiment, as shown in FIG. 29 and the like, the upper surface 16a and the lower surface 16b of the storage portion 16 are in contact with the battery 1. The upper surface 16a is in contact with the battery 1 via a cushion 22 that is an elastic material, and the lower surface 16b is in direct contact with the battery 1. As shown in FIG. 30 and the like, the cushion 22 is attached to the upper surface 16a of the storage portion 16 with an adhesive, a double-sided adhesive tape, or the like. As shown in FIG. 30, the cushion 22 has a predetermined thickness when the battery 1 is not housed, and when the battery 1 is housed in the housing portion 16 as shown in FIG. Is elastically deformed and crushed, and a force to return to the original shape by the elastic restoring force works, so that the battery 1 can be suppressed more firmly. For example, even if vibration or the like is applied to the battery 1 from the outside, the relative movement in the storage unit 16 of the battery 1 can be more reliably suppressed. Furthermore, by disposing the cushion 22 on the upper side, the weight of the battery 1 is not applied to the cushion 22 in a state where the power supply device 10 is installed, and the cushion 22 can be prevented from sagging with respect to long-term use and can be held for a long time. Good because it can.

  In the present embodiment, the battery 1 can be suppressed by the storage portion 16, that is, the case body 11, and a special fastener for fixing the battery 1 is not necessary, and the battery 1 can be held with a simple configuration. Further, at least the case body 11 constituting the housing 3 is preferably made of a material that is bent or has elasticity. In this way, for example, even if the outer dimensions of the battery 1 are somewhat large, the case body 11 can be bent to allow the battery 1 to be stored, and the battery 1 can be held more reliably. Such a material is, for example, plastic or resin, and for example, PP (polypropylene) may be used.

  Further, since the housing portion 16 has no circuit board and the arrangement of members other than the battery 1 is eliminated as much as possible, for example, the inner shape of the housing portion 16 is made substantially equal to the outer shape of the battery 1. In particular, since the battery 1 is held at the upper and lower surfaces of the case body 11, the height of the case body 11 is substantially equal to the height of the battery 1, and the height is suppressed. As will be described later, the heights of the front case 12 and the rear case 13 are also matched to the height of the case body 11. Therefore, the height in the vertical direction in the installed state of the power supply device 10 is obtained by adding the plate thickness of the case body 11 to the height of the battery 1, and the outer shape of the power supply device 10 is flat and thin. As described above, the power supply device 10 of the present embodiment is a device that supplies power to, for example, on-vehicle equipment, and the installation location is preferably a location that does not interfere with the driver or passengers. The place that does not get in the way is good, for example, a space under the driver's seat. The space under the driver's seat or the like is not so high, but the power supply device 10 of the present embodiment is flat and thin, so that it has a shape suitable for installation in a narrow space in the vertical direction. Become.

  Further, the length in the left-right width direction of the storage portion 16 is longer than the length of the battery 1, and a space 26 is secured between the left and right side surfaces 1a of the battery 1 and the inner surface of the storage portion 16 (FIG. 29). , See FIG. One of the left and right spaces 26 is connected to a communication hole 14 a provided in the partition wall 14. Then, using this space 26, the power cord 6 is arranged, and the first connector 7 attached to the power cord 6 is positioned in a space in front of the partition wall 14. In the present embodiment, the space 26 is for arranging the power cord 6. For example, if the battery 1 can be attached and detached including the placement of the power cord 6, the space 26 can be narrowed. If the space 26 is narrowed, the width of the case body 11 and thus the left and right sides of the housing 3 can be made to be approximately the same as the lateral width of the battery 1 and can be made more compact. It is preferable because it can be easily installed in a narrow space such as a space under the driver's seat. Further, in addition to the vertical height, the lateral width may be reduced according to the outer dimensions of the battery 1 so that the space for installation can be expanded even in a narrow space.

  As described above, there is only a limited space under the seat, and if the power supply device 10 is to be mounted in such a space, the thickness and height cannot be taken much. In this embodiment, since the battery 1 is not a thin lithium battery but a nickel metal hydride battery, there is a limit to reducing the thickness of the battery 1 itself. Therefore, since it is not preferable to arrange the circuit unit 2 on the battery 1, in this embodiment, a layout in which the storage unit of the circuit unit 2 is arranged on the front side of the storage unit 16 of the battery 1 is adopted. Further, for example, in the configuration in which the circuit board is arranged above the battery 1 or the like, the board does not become so large that the board is arranged on the entire upper surface of the battery 1. . On the other hand, as in the present embodiment, the battery 1 and the circuit unit 2 are arranged at the front and back, so that the overall size and shape can be reduced, the size can be reduced, and the size and shape of the battery can be made slightly longer. .

  In addition, since the installation place of the power supply apparatus 10 is set under the seat in this way, the temperature does not become higher than that on the dashboard, for example. Therefore, no temperature countermeasure is required when installing on such a dashboard. In this embodiment, since the housing | casing 3 is comprised from PP, it can respond by the heat resistance which such PP has.

* Structure on the front surface 11 a side of the case body 11 As described above, the partition wall 14 is provided in the case body 11. The partition wall 14 is formed at a position recessed from the front end of the case body 11 on the front surface 11a side. The cylindrical peripheral wall portion 11i on the front surface 11a side of the case main body 11 and the front end side space surrounded by the partition wall 14 serve as a circuit mounting portion 15 in a space where the substrate constituting the circuit portion 2 is mounted. A thin tip peripheral wall portion 11j is formed at the front end of the peripheral wall portion 11i. The inner peripheral surface of the tip peripheral wall portion 11j is flush with the peripheral wall portion 11i. The outer peripheral surface of the tip peripheral wall portion 11j is one step lower than the outer peripheral surface of the peripheral wall portion 11i. The distal end peripheral wall portion 11j coincides with the inner peripheral surface of the peripheral wall portion 12b of the front case 12 so that no positional deviation or the like occurs when the front case 12 is attached to the case main body 11.

  The tip peripheral wall portion 11j is formed over substantially the entire circumference along the peripheral wall portion 11i. A cutout portion 11k is provided on the side where the cover member 17 is mounted, and the tip peripheral wall portion 11j is not provided at that portion. Thus, when the cover member 17 is opened, the opening 3a is exposed, and the first connector 7 and the second connector 8 are attached / detached, a finger or the like can be inserted into the notch 11k. It is made easier.

  Moreover, the latching recessed part 11h which stops the cover member 17 is provided in the outer surface predetermined position in the arrangement | positioning area | region of the cover member 17 of the front-end | tip surrounding wall part 11j. A locking projection 11m for temporarily fixing the front case 12 is provided on the outer surface near the center in the longitudinal direction of the distal peripheral wall portion 11j.

  On the front surface 11a side of the case body 11, a plate member 36 that protrudes further forward from the tip of the tip peripheral wall portion 11j is provided. The position where the plate member 36 is provided is a flat portion on the upper surface and the lower surface, and is near the arc-shaped portion on the side where the cover member 17 is provided.

  A boss 34 is provided on the front side of the partition wall 14. The bosses 34 are arranged upright on both the left and right sides in the longitudinal direction toward the front. A female screw part 34 a is provided at the tip of the boss 34. A sheet-like first heat sink 42 is disposed in a region between the left and right bosses 34 on the front surface of the partition wall 14. The first heat sink 42 is fixed to the partition wall 14 with, for example, an adhesive or a double-sided adhesive tape. The first heat sink 42 is made of, for example, an aluminum sheet. In addition, the first heat sink 42 is provided with concave notches 42a at two locations to form a region where no aluminum sheet is present. A thermal sheet 43 is disposed in the concave cutout portion 42a. A part of the thermal sheet 43 is in contact with the first heat sink 42 and thermally connected thereto. The thermal sheet 43 is fixed to the partition wall 14 or the first heat sink 42 with an adhesive or a double-sided adhesive tape.

  In accordance with the position of the first heat sink 42, a projecting piece provided on the periphery of the first heat sink 42 is inserted into the hole 23 of the groove 24 provided in the case body 11 and fixed. The hole 23 serves both as a heat radiating function and as a fixing function. Since the position of the heat sink is aligned with the hole 23 provided in the groove 24, even a portion without a fixing protrusion functions as a heat radiating hole.

* Structure of the front case 12 etc. As described above, the opening on the front surface of the case body 11 is closed by the front case 12. The closing front case 12 has a bottomed cylindrical shape, and the rear surface in the front-rear direction is open. The front case 12 includes a front wall portion 12a and a peripheral wall portion 12b formed so as to extend rearward from the periphery of the front wall portion 12a. The front wall portion 12a has an elongated rectangular area and arc-shaped areas that are continuous on both the left and right sides of the rectangular area. One arcuate region is the top plate 17 a of the cover member 17. The peripheral wall 12b is an inclined surface / tapered surface that gradually widens from the front wall 12a side toward the rear, and the size and shape are gradually increased.

  The front wall portion 12a of the front case 12 is provided with an opening for an interface with the outside at an appropriate position. In the present embodiment, a first opening 12c for the input terminal portion 20, a second opening 12d for the output terminal portion 21, and a third opening 12e for the setting switch 27 are provided in this order from the cover member 17 side. A fourth opening 12f for the light emitting unit is provided above the third opening 12e. The fourth opening 12f has an arrangement in which six small circles are arranged in a line. The first opening 12c, the second opening 12d, and the third opening 12e are left open, and the fourth opening 12f is closed by applying a translucent seal 37. By leaving the first opening 12c, the second opening 12d, and the third opening 12e open, the operation of the input terminal unit 20, the output terminal unit 21, and the setting switch 27 disposed in each opening can be performed in the front case 12. It becomes possible to operate from the front side. Since the interface with the outside is arranged on the same surface, user convenience is improved.

  In the formation region of the first opening 12c of the front wall portion 12a, a shallow bottom recess 12g is formed, and the first opening 12c is provided in the recess 12g. The first opening 12c is formed at a position close to the case main body 11 side, with the outer surface of the front wall portion 12a as a reference position, being lowered one step from the reference position. This is based on the difference in height between the input terminal portion 20 and the output terminal portion 21. As will be described later, in this embodiment, the input terminal portion 20 and the output terminal portion 21 are mounted on the same substrate and face the front wall portion 12a. Thereby, the input terminal part 20 and the output terminal part 21 differ in the tip height position from the substrate surface. By shifting the formation positions of the first opening 12c and the second opening 12d according to the difference in position, the tips of the input terminal portion 20 and the output terminal portion 21 are both positioned at the first opening 12c and the second opening 12d. To do.

  The formation area of the third opening 12e of the front wall portion 12a is formed with a recess 12h, and the third opening 12e is provided in the recess 12h. The recess 12h is made deeper than the recess 12g. Since the operation surface of the setting switch 27 is located deeper on the case body 11 side than the surface of the front wall portion 12a which is the reference position, the user or the like accidentally touches the setting switch 27 and the setting is changed. Suppress as much as possible.

  The concave portion 12h has an opening portion 12h ′ in which the upper surface side of the peripheral wall portion 12b is opened. For the operation of the setting switch 27, for example, the user may be positioned so that the finger is released from the opening portion 12h ′ to the outside of the front case 12 with the fingertip positioned near the operation surface of the setting switch 27. Can be set easily. Furthermore, since the opening portion 12h ′ is formed on the upper surface side of the peripheral wall portion 12b that is on the upper side with the housing 3 placed, the user can perform the setting operation with the housing 3 placed.

  A fourth opening 12f is provided in the recess 12h. As a result, the position of the light emitting unit is also a position recessed from the reference position of the front wall portion 12a, and approaches a light emitting source such as an LED disposed inside the front case 12. The light emitting unit of the present embodiment is configured to guide the light emitted from the light emitting source to the light emitting unit and radiate the light to the outside so that the user can visually recognize the light from the outside. It is good because the light guide path for guiding the light can be shortened. The light guide path is configured by ribs 38 formed in accordance with the arrangement pitch of the fourth openings 12f. The rib 38 has a flat plate shape, and two adjacent sides are connected to the front wall portion 12a and the inner surface of the peripheral wall portion 12b on the side where the opening portion 12h ′ is provided. When the front case 12 is mounted on the case main body 11, if the side of the rib 38 opposite to the front wall portion 12a is configured to be in contact with or close to the substrate surface on which a light emitting source such as an LED is mounted, the adjacent LED It is good because the wraparound of light from the light can be suppressed. Further, by providing the recess 12h and bringing the fourth opening 12f close to the light emitting source, the dimension of the rib 38 can be shortened, so that a more accurate dimension can be obtained. In the visible configuration of the present embodiment, a semi-transparent seal 37 is attached to the fourth opening 12f, and the light emitted from the light emitting source reaches the fourth opening 12f via the light guide path, and the fourth opening 12f The arrived light passes through the seal 37 and is emitted to the front outside of the housing 3 and the front case 12.

  Furthermore, the recessed part 38a is provided in the connection side with the surrounding wall part 12b of the edge | side of the rib 38 on the opposite side to the front wall part 12a. In a state where the front case 12 is mounted on the case main body 11, the front end of the front peripheral wall portion 11j of the case main body 11 enters the recess 38a, and the connection between the case main body 11 and the front case 12 is further strengthened.

  A first inner wall 31 and a second inner wall 32 are provided on the cover member 17 side inside the front case 12. The first inner wall 31 is connected to the inner surfaces of the front wall portion 12a and the peripheral wall portion 12b of the front case 12, and a space surrounded by the front wall portion 12a, the peripheral wall portion 12b and the first inner wall 31 of the front case is formed. This space constitutes a space for housing the circuit unit 2. Thereby, regardless of the open / closed state of the cover member 17, the entry of dust, foreign matter, etc. into the space stored in the substrate is suppressed. The first inner wall 31 is formed at a position slightly inside the hinge portion 18. Furthermore, the recessed part 31a is provided in the connection side with the surrounding wall part 12b of the edge | side of the 1st inner wall 31 on the opposite side to the front wall part 12a. In a state where the front case 12 is mounted on the case main body 11, the tip of the front peripheral wall portion 11j of the case main body 11 enters the recess 31a, and the connection between the case main body 11 and the front case 12 is further strengthened.

  The second inner wall 32 is disposed outside the first inner wall 31 and is formed at substantially the same position as the end of the hinge portion 18 on the nearest cover member 17 side. For example, as shown in FIG. 9 and the like, the inside of the front case 12 is hidden by the second inner wall 32 in a state where the cover member 17 is opened. The appearance is also beautiful, and the finger or the like does not touch the circuit unit 2. The second inner wall 32 is connected to the front wall portion 12a of the front case 12, and a gap 35 is formed between the second inner wall 32 and the peripheral wall portion 12b. A plate member 36 erected on the front surface 11 a side of the case body 11 enters and closes into the gap 35.

  On both longitudinal sides of the inner surface of the front wall portion 12a of the front case 12, bosses 33 extending backward are provided. The boss 33 has a cylindrical shape with both ends open, and has a bottom 33a with a center open at the tip opposite to the front wall 12a. When the fixing screw 39 is inserted from the portion opening to the front wall portion 12a side, the head of the fixing screw 39 stays in contact with the bottom portion 33a. When the front case 12 is mounted on the case main body 11, the boss 33 is positioned so as to face the boss 34 provided on the case main body 11. When the fixing screw 39 is tightened in this state, the male screw portion of the fixing screw is fastened and fixed to the female screw portion 34a of the boss 34.

  The boss 33 on the cover member 17 side is in contact with the first inner wall 31 and is fixed near the boundary with the cover member 17. Even when the cover member 17 is repeatedly opened and closed, the state in which the front case 12 is firmly fixed to the case body 11 can be maintained, and the cover member 17 can be opened and closed stably by being fixed near the hinge portion 18. Further, the boss 33 opposite to the cover member 17 is formed near the center of the semicircle of the arc-shaped region. In the present embodiment, since the left and right sides of the housing 3 are formed in an arc shape in accordance with the outer shape of the battery 1, it is difficult to dispose elements / parts in that portion. Effective use of dead space that is difficult to place.

  On the inner surface of the peripheral wall portion 12b, an elongated strip-like rib 40 extending in the front-rear direction is provided. Two adjacent sides of the rib 40 are connected to the front wall portion 12a and the peripheral wall portion 12b. When the front case 12 is attached to the case body 11, the side of the rib 40 opposite to the front wall portion 12a is the surface of the substrate. It was comprised so that it might contact. The rib 40 is a reinforcing rib so that the peripheral wall portion 12b does not swell or dent. Furthermore, the recessed part 40a is provided in the connection side with the surrounding wall part 12b of the edge | side of the rib 40 on the opposite side to the front wall part 12a. In the state where the front case 12 is mounted on the case main body 11, the tip of the front peripheral wall portion 11j of the case main body 11 enters the recess 40a, and the connection between the case main body 11 and the front case 12 is further strengthened.

  Furthermore, a locking recess 12i is provided on the inner surface of the peripheral wall portion 12b. In this embodiment, one locking recess 12i is provided on each of the upper surface side and the lower surface side. When the front case 12 is mounted on the case main body 11, the locking recess 12i is preferably used for matching and temporarily fixing the locking protrusion 11m.

* Structure of the cover member 17, etc. As described above, the opening 3a of the housing 3 is provided on one of the left and right side surfaces (for example, the left side) of the front case 12, and the cover member 17 covering the opening is attached to the front case. 12 is formed integrally. In the present embodiment, one side surface of the front case 12 constitutes the cover member 17. The cover member 17 includes a semicircular top plate 17a and an arcuate peripheral wall 17b extending rearward continuously from the outer peripheral edge of the top plate 17a. The peripheral wall 17 b is the same as the peripheral wall portion 12 b of the front case 12. As described above, the top plate 17 a and the front wall portion 12 a of the front case 12 are connected via the hinge portion 18. In the state where the cover member 17 is closed, a gap S is formed between both end edges 17b ′ of the peripheral wall 17b and the peripheral wall portion 12b of the front case 12. The plate member 36 is located on the back side of the gap S. When the cover member 17 is closed, the plate member 36 functions as a blindfold, the inside is not visible from the gap S, and the appearance is improved. The entry of foreign matter such as dust can also be prevented.

  Moreover, the handle part 17f which protrudes outside is provided in the center part of the free end side (side / back surface side away from the top plate 17a) of the outer peripheral surface of the peripheral wall 17b. Further, a locking projection 17g is provided at an appropriate position on the free end side of the inner peripheral surface of the peripheral wall 17b. In the present embodiment, two handle portions 17f are provided at positions shifted from the center of the peripheral wall 17b by a predetermined distance to the left and right.

  When the cover member 17 is closed, the locking protrusion 17g and the locking recess 11h provided on the distal peripheral wall portion 11j of the case body 11 are fitted to each other, and the cover member 17 is held closed. .

  Thereby, when the cover member 17 is in the closed state as shown in FIG. 1A and the like, when the user hangs his finger on the handle portion 17f and urges the finger toward the top plate 17a, the locking projection 17g is engaged. The opening 3a is released from the stop recess 11h (see FIG. 1B, etc.). On the other hand, when the opening 3a is in the open state, the user presses an appropriate position of the cover member 17 to close the cover member 17 and close the opening 3a. Then, the locking projection 17g fits into the locking recess 11h, and the closed state is maintained. When this fits, for example, a sound such as “click” sounds, so that the user can confirm the fit.

[Specific Configuration of Circuit Unit 2]
* Circuit part In this embodiment, the circuit part 2 is comprised with a printed wiring board. As shown in FIGS. 22 to 25 and the like, the substrate is formed using two substrates. The circuit part 2 interposes the spacer member 53 between the first substrate 51 and the second substrate 52, and fixes them with screws in a state where they are overlapped. The first substrate 51 and the spacer member 53 are fastened with screws 54, and the second substrate 52 and the spacer member 53 are fastened with screws 55.

  On the first substrate 51, the input terminal portion 20, the output terminal portion 21, the setting switch 27, the LED 56, the microcomputer 57, the second connector 8, and the like are disposed on the surface side. On the back surface side of the first substrate 51, a first connection connector 58, electronic components constituting various circuits, and the like are arranged. On the surface side of the second substrate 52 (side facing the partition wall 14), a coil element 59, an IC 60, electronic components constituting various circuits, and the like are arranged. On the back side of the second substrate 52 (the side facing the first substrate 51), the second connection connector 61, electronic components constituting various circuits, and the like are arranged. The first connection connector 58 and the second connection connector 61 have a power supply line and a communication line, and perform power supply and data transmission / reception between the circuit of the first substrate 51 and the circuit of the second substrate 52.

  The spacer member is configured using a member having good thermal conductivity, and in this embodiment, an aluminum plate is used. The first substrate 51 and the second substrate 52 can be arranged so as to overlap each other with a desired interval by interposing a spacer member 53. Further, the spacer member 53 can dissipate heat or be diffused by heat and partially. Since it has a function of suppressing high temperature, the heat generated in the circuit unit 2 is released, and high heat is prevented from being transmitted to the storage unit 16 side of the battery 1.

  A second heat sink 63 is disposed on the surface side of the second substrate 52. The second heat sink 63 is configured by using an aluminum plate so as to cover the second substrate 52 with a predetermined distance from the surface of the second substrate 52. The second heat sink 63 is fixed to the second substrate 52 and the spacer member 53 with screws 55.

  When the thermal sheet 65 is bonded to the upper surface of the IC 60 and the second heat sink 63 is mounted, the surface of the thermal sheet 65 is in contact with the second heat sink 63. Thereby, the heat generated in the IC 60 is transmitted to the second heat sink 63 via the thermal sheet 65 and is radiated.

  The second heat sink 63 was not provided on the coil element 59. Further, in a state where the second substrate 52 is mounted in the front case 12, the coil element 59 faces the concave notch 42 a of the first heat sink 42. Thus, the first heat sink 42 and the second heat sink 63 are not positioned on the head of the coil element 59 (the surface opposite to the surface attached to the substrate). Since the head of the coil element 59 used in the present embodiment is a surface through which a magnetic field enters and exits, if a metal such as aluminum is disposed on the head, the coil characteristics are deteriorated. In the present embodiment, since the head is not covered with a metal such as aluminum, the characteristics and effects intended by the coil element 59 can be obtained. The head of the coil element 59 is in contact with the thermal sheet 43 provided on the partition wall 14, and is thermally diffused to the first heat sink 42 side through the thermal sheet 43 to be radiated. Further, a cushion 66 is installed at a position adjacent to the coil element 59. The cushion 66 is provided at a position corresponding to a connection portion between the thermal sheet 43 and the first heat sink 42 so that the thermal sheet 43 is brought into contact with the first heat sink 42 with a predetermined pressure by using the elastic restoring force of the cushion 66. I have to. As a result, the thermal sheet 43 and the first heat sink 42 are in surface contact with each other and heat dissipation efficiency is improved.

  Further, in the present embodiment, heat generated from the coil element 59 is radiated using the first heat sink 42, and heat generated from the IC 60 and other components other than the coil element 59 is radiated using the second heat sink 63. Since the level of heat generation is different between the coil element 59 and other parts, for example, if the heat generated from the coil element 59 is also passed through the second heat sink 63, the high heat is transmitted to the IC 60 and other parts and cannot be properly radiated. Occurs. Therefore, in this embodiment, heat is radiated separately, and the heat generated from each is radiated efficiently.

  An insulating film 67 is applied to the surface of the substrate that contacts the spacer member 53. This prevents the wiring pattern from being short-circuited via the spacer member 53. The insulating film 67 becomes a thermal resistance. Therefore, preferably, the spacer member 53 is made to face the ground pattern, and the ground pattern is brought into direct contact with the exposed portion to increase the heat dissipation / heat conduction efficiency. Further, it is preferable that the surface of the spacer member 53 is not contacted with the portion facing the normal wiring pattern instead of the ground pattern. However, since the processing is complicated, it is preferable to contact the above-described ground pattern.

  Further, in the present embodiment, a structure in which two sheets are overlapped like the first substrate 51 and the second substrate 52 is employed. Thus, for example, by disposing elements that generate heat on a plurality of substrates, heat can be efficiently radiated.

  As described above, the partition wall 14 is formed at a position recessed from the front end of the case main body 11 on the front surface 11 a side, and the circuit portion 2 is in the front end space surrounded by the partition wall 14 and the peripheral wall portion 11 i of the case main body 11. A first substrate 51 and a second substrate 52 are mounted with a spacer member 53 interposed therebetween. In the mounted state, the surface of the first substrate 51 is positioned near the tip of the peripheral wall portion 11i. If it does in this way, the 1st board | substrate 51 and the 2nd board | substrate 52 can be accommodated in the case main body 11, and the board | substrate should just be settled in the front end side space of the case main body 11. FIG.

  Further, since the surface of the first substrate 51 is located in the vicinity of the tip of the peripheral wall portion 11i and is not recessed from the tip, for example, the distance between the surface of the first substrate 51 and the front wall portion 12a of the front case 12 Can be brought closer. Then, when various external interfaces are mounted on the surface of the substrate, even when a member having a low interface height is used, the interface can be positioned in the vicinity of the surface facing the housing portion of the first case. I can do it.

* Arrangement structure of the second connector, etc. As described above, in the present embodiment, the second connector 8 is directly attached to one end side in the longitudinal direction of the first substrate 51. The insertion / removal direction of the first connector 7 with respect to the second connector 8 is along the first substrate 51, and when the power supply device 10 is installed, the insertion / removal is performed from the upper side to the lower side. The terminal pin 8 a of the second connector 8 is bent into an L shape, and the tip of the terminal pin 8 a is connected to a wiring pattern that is electrically connected to the circuit portion 2 of the first substrate 51.

  If it does in this way, since the 2nd connector 8 is being fixed to the 1st board | substrate 51, it is not necessary to hold down the 2nd connector 8, and it becomes easy for a user to hold the 1st connector 7 and to insert / remove. Then, for example, the user can easily remove the first connector 7 and the second connector 8 to protect the battery 1. Moreover, the direction of the second connector is specified by fixing the second connector 8 to the substrate. In this embodiment, when the cover member 17 is opened, the direction in which the second connector 8 is inserted is also opened, so that the connector can be easily attached and detached. For example, the user can feel free to connect the first connector 7 when the apparatus is not used. It is only necessary that the second connector 8 be removed.

  Further, since the direction of insertion / removal of the first connector 7 is the direction along the surface of the first substrate 51, the first connector 7 only needs to be moved along the first substrate 51 when the connector is attached / detached. Since it improves, it is preferable.

  In this embodiment, the tip of the tip peripheral wall 11j of the case body 11 and the surface of the first substrate 51 are substantially the same, the first substrate 51 is slightly lowered, and the first connector 7 is attached to the first substrate 51. It is configured to move in contact with the second connector 8. For example, the user may be able to attach and detach the connector by moving the first connector 7 against the first substrate 51 while moving the substrate. In the present embodiment, since the opening 3a of the housing 3 is three-dimensionally provided, a finger or the like can be inserted from different directions, and workability is improved. When the cover member 17 is opened, the top plate 17a rotates around the hinge portion 18, the surface facing the first substrate 51 opens, and workability when pressing the first connector 7 against the substrate, for example, the finger This is preferable because a movement space can be secured.

  Moreover, in this embodiment, since the 2nd connector 8 was directly attached to the 1st board | substrate 51, the space for accommodating becomes small, and the 1st connector 7 and the 2nd connector 8 are settled in the space of the cover member 17. FIG. For example, when the second connector 8 is connected to the first substrate 51 via a wiring cord, for example, the connector size that can be used as the second connector 8 is first compared to the on-board type of the present embodiment. Will become bigger. Further, the wiring cord corresponds to the battery capacity and is thick and difficult to bend like the power cord, and a large space for caulking the wiring cord to the connector and routing the wiring cord is required. Therefore, there is a possibility that it does not fit in the space of the cover member 17 of this embodiment. On the other hand, in the case of the on-board as in this embodiment, the terminal pin can be bent and directly connected to the first substrate 51 by soldering, the space for the wiring cord is not required, and the connector size can be reduced. Therefore, the space for storage may be reduced.

  Circuit portions other than the wiring pattern are not arranged on the cover member 17 side, and are configured not to be exposed from the opening 3a even when the cover member 17 is opened. Circuit portions other than the wiring pattern are positioned in a space surrounded by the front wall portion 12 a, the peripheral wall portion 12 b and the first inner wall 31 of the front case 12. In this way, when the first connector 7 and the second connector 8 are attached and detached, it is possible for the user to accidentally touch the components / elements of the circuit unit 2 or to mix foreign objects as much as possible. It is good because it can be suppressed.

[Removable structure of case body 11 and rear case 13]
As shown in FIGS. 28 to 31 and the like, the rear surface 11b of the case body 11 has a rectangular shape below the left and right side surfaces. As described above, the left and right sides of the case main body 11 have an arc shape corresponding to the side surface shape of the battery 1, and the arc shape is formed over almost the entire length in the front-rear direction. And the lower part of the side surface near the rear surface 11b is not straightened but formed substantially straight. Thereby, as for the outer shape of the case body 11 near the rear surface 11b, the lower half is rectangular, and the upper half is arc-shaped on both sides like the other parts.

  The flat portion 11c formed straight is thicker than the other side surfaces. A through hole 11d that penetrates the inside and outside of the case body 11 is formed in the flat portion 11c. Further, a concave portion 11e having a large inner diameter is formed concentrically with the through hole 11d on the outer surface side of the flat portion 11c. A screw portion of a bolt (not shown) is in a through state in the through hole 11d, and a head portion of the bolt is located in the recess 11e.

  In addition, on the upper side and the lower side of the rear surface 11b of the case body 11, projecting pieces 11f that protrude rearward are formed. The thickness of the projecting piece 11f is thinner than the thickness of the upper side and the lower side of the case body 11, for example, about half, and is located on the inner peripheral surface side. The inner peripheral surface of the case body 11 and the inner surface side of the projecting piece 11f are formed flush with each other. Accordingly, the outer surface side of the projecting piece 11 f is positioned at a position one step lower than the outer surface of the case body 11.

  On the other hand, the rear case 13 has a body portion 13a having a bottomed cylindrical shape, and a front surface 13b in the front-rear direction is opened and a rear surface 13c is closed. The main body portion 13 a is a portion exposed to the outside in a state of being mounted on the case main body 11. Further, the front surface 13b of the main body portion 13a is provided with substantially triangular protrusions 13d protruding in the direction parallel to the front surface 13b at the lower left and right ends thereof. The protrusion 13d faces the flat portion 11c of the case body 11, and the protrusion 13d is provided so that the outer peripheral edge of the front surface 13b of the main body portion 13a including the outer peripheral edge of the protrusion 13d is flat. If it takes the shape similar to the rear surface 11b including the part 11c and contacts the front surface 13b of the main body part 13a of the rear case 13 and the rear surface 11b of the case body 11, the outer peripheral surface is smoothly connected without a step.

  Further, a peripheral wall portion 13e whose outer shape is slightly smaller than the main body portion 13a is formed on the front surface 13b of the main body portion 13a so as to protrude forward. The inner peripheral surface of the peripheral wall portion 13 e is connected to the inner peripheral surface of the main body portion 13 a, and the outer peripheral surface of the peripheral wall portion 13 e has a dimension that matches the inner peripheral surface of the case main body 11. When the rear case 13 is mounted on the rear surface 11 b of the case body 11, the peripheral wall portion 13 e is inserted into the case body 11. Thereby, the peripheral wall part 13e fits in the case main body 11, and the rear case 13 is restricted from moving in a plane parallel to the rear surface 11b of the case main body 11.

  Furthermore, the end surface of the front surface 13b of the main body portion 13a is provided with a concave groove 13h at a boundary portion with the outer peripheral surface of the peripheral wall portion 13e. The recessed groove 13h is formed at a position facing the protruding piece 11f, and is set so that the protruding piece 11f is inserted into the recessed groove 13h when the rear case 13 is mounted on the case body 11. When the protruding piece 11f enters the concave groove 13h, the rear surface 11b side of the case main body 11 is prevented from being bent in the vertical direction. The width of the case main body 11 in the vertical direction is restricted, and the battery 1 can be firmly sandwiched from above and below.

  A nut storage portion 13f is provided below the side surface of the peripheral wall portion 13e. The nut storage portion 13f is installed at a position facing the flat portion 11c provided on the rear surface 11b side of the case main body 11. The nut storage portion 13f stores the nut 25. A through hole 13g is formed on the side surface of the nut storage portion 13f. The female screw of the nut 25 housed in the nut housing portion 13f is located concentrically with the through hole 13g, and the through hole 13g penetrates the flat portion 11c when the rear case 13 is mounted on the case body 11. Opposite the hole 11d and located concentrically. In this state, a bolt is inserted into the through hole 11d and the through hole 13g from the outside of the housing 3, and the bolt and the nut 25 stored in the nut storage portion 13f are fastened. Thereby, the case main body 11 and the rear case 13 are connected. Thus, in this embodiment, since it fixes from the side of the housing | casing 3, it is good because a connection and fixing structure can be comprised in a small space. The left and right side surfaces of the housing 3 have an arc shape extending over the entire length, and only the region fixed with the bolt and nut protrudes outward from the arc-shaped side surface. It is housed in the shape so that it does not protrude significantly. In addition, since the region to be fixed with the bolt and nut is configured not to protrude outward from the outermost position of the arc-shaped side surface, the region is inconspicuous and is designed to follow the outer shape of the battery. An arc-shaped side surface is conspicuous, which is preferable.

  In the present embodiment, since the rear case 13 is fixed by fastening bolts and nuts from the side of the housing 3, even if there is a large vibration, the rear case 13 comes off and the battery 1 pops out. To prevent that. The reason why the side-by-side fastening structure is used in this way is that, for example, when screwing from the rear surface side of the rear case 13, the partition wall 14 is positioned on the front surface 11 a side. It is difficult to form the long boss because a long boss that extends in a long distance must be arranged and the battery 1 is almost entirely in the storage portion 16. Further, for example, by forming flanges projecting toward the outer periphery on the joint end surfaces of the case body 11 and the rear case 13, and fixing the bolts and nuts so as to sandwich the flanges with the flanges attached together Although it may be fixed in the front-rear direction, if such a configuration is adopted, the strength of the flange is ensured, and the flange portion protrudes greatly, which is not preferable in terms of design. On the other hand, in this embodiment, the dead space that is no longer used by making the side surface arc-shaped is used, leaving the corners of the parts where the bolts and nuts are placed, and the bolts are mounted from the side. Since it can be fixed without providing a flange or the like, it is preferable in terms of design, and since it can be formed compactly, it may be suitable for installation in a narrow space.

  As described above, the connection between the front case 12 and the case main body 11 is performed by attaching a screw from the front wall portion 12a side of the front case 12. The front case 12 may be fixed from the side as in the case of the rear case 13. However, since the cover member 17 is provided on one side, it is difficult to adopt a structure that is fixed from the side on the left and right sides as in the case of the rear case 13. In addition, since the same arc-shaped side surface as the case main body 11 is formed over the entire length up to the front case 12 side, it is preferable in terms of design. Further, it is more preferable to fix from the front side because the first substrate 51 and the second substrate 52 can be fixed simultaneously. Further, since the partition wall 14 is formed on the front surface 11a side of the case main body 11, the bosses 33 and 34 for screwing can be short, so there is no problem in manufacturing.

  Further, in the present embodiment, the nut housing portion 13f is opened on the front surface 13i side in order to set the nut 25, and further, a recess 13j is formed on the lower surface. A rib 11g that protrudes upward from the lower surface side is formed on the inner peripheral surface of the case body 11 facing the nut housing portion 13f. When the rear case 13 is attached to the case main body 11, the rib 11g enters the nut storage portion 13f from the front surface 13i side of the nut storage portion 13f and coincides with the recess 13j. Thereby, the case main body 11 and the rear case 13 are firmly connected also by the fitting of the rib 11g and the recess 13j.

  A large number of grooves 24 extending in the left-right direction are formed on the outer surface of the upper surface and the lower surface of the case body 11. Holes 23 penetrating inside and outside are provided at predetermined positions in some of the plurality of grooves 24. In a region corresponding to the storage portion 16, a total of two hole portions 23, one at each of the left and right ends, are provided in one groove 24. The hole portion 23 constitutes a heat radiating port and suppresses the inside of the storage portion 16 from being heated due to natural convection and natural heat radiation. Further, the hole 23 is also formed in the groove 24 located in the region corresponding to the space for storing the circuit portion 2 on the front side of the partition wall 14. The holes 23 provided in the region corresponding to the space for storing the circuit portion 2 are formed at a higher density than the storage portion 16 side. For example, the structure formed at a high density increases the number of holes 23 formed in one groove 24 or reduces the arrangement pitch of the grooves 24 forming the holes 23 to reduce the pitch per unit length in the front-rear direction. Some increase the number of grooves 24 with holes 23. In the present embodiment, both are employed, six holes 23 are formed in one groove 24, and the holes 23 are formed in all the grooves 24. Since the circuit part 2 side generates more heat, the holes 23 are arranged at a high density to further enhance the heat dissipation effect and to suppress the heat generated on the circuit part 2 side from being transmitted to the battery 1 as much as possible. I am doing so.

  Further, since the hole 23 is formed in the groove 24, it is difficult to understand that the hole 23 is formed, and the user does not notice the presence of the hole 23 or is in the back of the groove 24 even if it is noticed. It ’s good because I do n’t care much.

[Fixing structure of power supply device 10]
A hook-and-loop fastener 74 may be attached to the lower surface side of the case main body 11 and fixed and detachably attached via the hook-and-loop fastener 74. In this embodiment, it is used as an external power source for in-vehicle devices, and its installation location is a space below the driver's seat or the like. In the space below the driver's seat, there are many vehicles on which carpets are present. The hook-and-loop fastener 74 of the present embodiment is a special one having a property and structure that can be attached to a carpet. The hook-and-loop fastener 74 is a hook-side hook-and-loop fastener 74 so as to be attached to the carpet. The surface fastener 74 is affixed using a double-sided tape that affixes to the PP that is the material of the case body 11. The hook-and-loop fastener 74 may be used for direct connection and fixing to the vehicle carpet. In a place where there is no carpet, a loop-side hook and loop fastener that sticks to the hook-and-loop fastener 74 is also attached to the vehicle side, and it may be detachably fixed to the vehicle-side hook and loop fastener.

  Furthermore, in the present embodiment, projecting pieces 70 projecting sideways are formed at two positions on the front and rear sides of the left and right side surfaces of the case body 11, and through holes 71 penetrating vertically are provided in the projecting pieces 70. The projection 70 and the through hole 71 are also used to fix the installation location. For example, bolts may be inserted into the through holes 71 and fixed using bolts and nuts. In this way, since the power supply device 10 can be fixed more firmly, for example, the power supply device 10 can be held at the installation location even when used in a place where vibration is large. Moreover, you may fix with a tie wrap etc. using the through-hole 71 which concerns. Using a tie wrap makes it easy to fix and install.

  On the side surface adjacent to the projecting piece 70 of the case body 11, a recess 72 extending in the vertical direction is provided. The recess 72 secures a space for a wrench used for tightening the bolt.

  In the present embodiment, power is supplied to the in-vehicle device. Since the vibration applied to the power supply device 10 is about 3G at the maximum if it is a usage target, the hook-and-loop fastener 74 may be fixed. Therefore, if it is exclusively for in-vehicle use, the projecting piece 70 or the like is not provided, and the design can be made with a clean and unified sense that is formed in an arc shape over the entire length in the front-rear direction. On the other hand, by providing the projecting piece 70 as in the present embodiment and providing a plurality of different fixing structures, it may be possible to install in a place where a larger vibration occurs.

  Use in locations where larger vibrations occur, for example, surveillance cameras and factories (for example, confirming the operation of newly installed machine tools (for example, photographing and recording the operation when an NG product is created) In order to verify the cause of the occurrence of NG, install a camera near the machine tool and record it.The installation site has a lot of vibration (for example, about 10G). In addition, a fixing structure using the through-hole 71 of the projecting piece 70 is adopted even when it is installed in a vehicle or applied to a device that generates a large vibration such as a forklift. Powering a drive recorder that shoots the entire 360-degree circumference and rotates on the spot and shoots the surroundings in the same way as a normal vehicle In may be used.

[Battery replacement]
As described above, the space formed by the case main body 11 and the rear case 13 is the storage portion 16 of the battery 1. The rear surface of the case body 11 is open, and the opening serves as an outlet for the battery 1. When the rear case 13 is removed, the rear surface 11b of the case body 11 is opened, and one end side of the battery 1 protrudes to the outside (see FIG. 28, FIG. 29 etc.). Then, by removing the first connector 7 and the second connector 8, the battery 1 can be attached to and detached from the housing portion 16 from the rear surface 11 b side of the case body 11. Thus, in this embodiment, the battery 1 can be replaced.

  In the present embodiment, since the battery 1 is replaced from the rear surface 11b side of the case body 11 that is opened by removing the rear case 13, there is no need to remove the circuit unit 2 at the time of the replacement. Can do the replacement work on their own.

  In the present embodiment, the left and right sides of the case body 11 are arcuate. Using this arc-shaped side surface, the power cord 6 is easily guided to the front case 12 side. That is, the storage portion 16 for storing the battery 1 of the case body 11 is close to the dimensions of the battery 1 and has no room, so the space 26 is also narrow. The user inserts the power cord 6 into the storage portion 16 with the first connector 7 at the top, and further pushes the power cord 6 together with the battery 1 while the position of the first connector 7 cannot be confirmed. When the first connector 7 is pushed so as to contact the inner surface of the arc shape, the arc-shaped tip, that is, the left end in the left-right direction is naturally guided to the outer side from the communication hole 14 a provided in the partition wall 14. Can be put out. Since the communication hole 14a continuously opens on the arc-shaped inner peripheral surface, the first connector 7 can be smoothly brought out.

  In the present embodiment, the side surface of the housing 3 has an arc shape in accordance with the outer shape of the battery 1. When the arc shape is formed, there are no corners, and a wiring pattern or an element on the circuit board hardly occurs, and a dead space appears. The dead space is used for the wiring area of the power cord 6 or the storage space for the first connector 7 and the second connector 8.

  In the present embodiment, as described above, mechanical switching is performed to cut off the energization from the battery 1 to the circuit unit 2 by switching the current from the battery 1 to the circuit unit 2 by attaching and detaching the connector. There is no power ON / OF switch. In the case of the battery 1 that can be removed from the housing 3, it is necessary to release the connection with the circuit unit 2 in the housing 3 when removing the battery 1, and a connector is connected to the power cord in order to easily release the connection. In this embodiment, the battery is used, and the battery 1 including the power connector 6 and the first connector 7 is used. In this way, the connector originally necessary for such a purpose is also used as the first connector 7 for cutting off the current flowing from the battery 1 to the circuit unit 2 when power is not supplied to the device. The mechanical power ON / OFF switch is not provided, and the size is reduced with a simple configuration. In particular, in this embodiment, there is a case where power is supplied to on-vehicle equipment. When the terminal voltage of the battery 1 is set to 12 V in accordance with the battery voltage of the vehicle and the charging current is about 2 A, for example, a corresponding mechanical switch is also provided. Since a large one is required, the effect of reducing space by not providing the switch is increased.

  Furthermore, if the power supply device 10 of this embodiment is placed in a hidden place such as under a seat, for example, it is in a place where it is difficult to operate in the first place, and even if a switch is provided, the operability does not improve much. Therefore, the operation of opening the cover member 17 and removing the connector is not much different from the switch operation, and the space reduction effect is more effective, which is preferable.

[Use status of power supply unit / Example of equipment supplied with power]
The device to be supplied with power by the power supply device of the present embodiment may be, for example, an in-vehicle device. Some in-vehicle devices operate, for example, with a vehicle battery receiving power supply. To protect the vehicle battery, power is supplied from the vehicle battery to the in-vehicle device when the engine is on, such as when the vehicle is running or idling. When the engine is off, the in-vehicle device is turned off. There is something to do. The power supply device 10 of the present embodiment may be used, for example, to supply electric power to the in-vehicle device in a state where the engine or the like is OFF and the vehicle is parked or stopped so that the in-vehicle device can operate. The vehicle-mounted device that operates when the vehicle is parked and stopped in this manner may be a drive recorder, for example. The drive recorder has a function of recording surroundings during traveling and recording a certain period before and after the occurrence of an impact when an accident occurs. Therefore, while the vehicle is parked or stopped, the power supply device 10 continues to supply power to the drive recorder, and the surroundings of the vehicle are recorded. For example, when a shock occurs, a certain period of time is recorded. This can be used as a surveillance camera while parked.

  FIG. 38 shows an example of a connection form with the outside when power is supplied to the in-vehicle device. A connector 76 attached to one end of the power cable 75 is attached to the input terminal portion 20, and the other end of the power cable 75 is connected to a vehicle battery. A connector 78 attached to one end of the connection cable 77 of the in-vehicle device is connected to the output terminal portion 21, and the other end of the connection cable 77 is connected to the in-vehicle device. Further, as described above, the in-vehicle device is, for example, a drive recorder, and has a function of performing data communication with the drive recorder using the connection cable 77 in addition to power supply.

  The setting switch 27 is a switch for setting a recording time after the engine or the like is turned off, for example. The recording time is, for example, a maximum of 12 hours, and several preset times are designated by the setting switch 27. The power supply device 10 supplies power for the time set by the setting switch 27 and then turns off the output.

  The microcomputer 57 performs the power supply ON / OFF control and communication control. The microcomputer 57 also has a function of monitoring the voltage of the built-in battery 1 and turning off the output when the voltage drops without reaching the set recording time. As described above, for example, the charging circuit stops charging when the voltage of the battery 1 becomes lower than the reference value. Therefore, in order to prevent such a situation from occurring, the charging circuit is set to a constant voltage (for example, 10 V) provided with a margin according to the reference value. When it becomes, the operation is stopped.

  The communication with the drive recorder may be used, for example, for setting the recording time from the drive recorder side. Although the operation of the setting switch 27 is complicated, if the recording time is changed from the drive recorder side, the recording time can be changed according to the parking place and other conditions, and the recording time is unnecessarily long. It is good because it is possible to suppress the consumption. The setting switch 27 also sets whether or not the connected dry recorder has a communication function. For those without a communication function, the recording time is set by the setting switch.

  Further, in the communication of the drive recorder, for example, when a cancel area that is not recorded even when parked or stopped such as a garage at home can be set, the power supply apparatus 10 is notified that power supply is unnecessary if the cancel area is set. As a result, the power supply device 10 stops output even within the set recording time when the engine or the like is turned off.

  The drive recorder may recognize whether it is operating with power supplied from the battery 1 or power supplied from the vehicle battery, and may change the recording frame rate accordingly. In this way, when the engine or the like is off and the battery 1 is driving, for example, by reducing the frame rate or recording in the frame advance state, it is possible to reduce the consumption and voltage drop of the battery 1. I can do it.

  The power supply device of the present embodiment is particularly suitable for people who only occasionally drive. “Don't drive occasionally” means, for example, that you don't ride for a week or a month. Since the drive recorder is operated after getting off when the engine is off, the connector is removed at least after the operation of the drive recorder is stopped. For example, when the user stops in the home garage at night and photographs the surroundings with a night drive recorder, the user performs processing such as removing the connector on the next morning when the user is not driving.

  The battery 1 is fully charged after traveling for 3 hours, for example. For example, in summer, since the temperature becomes high, the battery 1 may not be fully charged even after 3 hours.

[Modification of the second connector attached to the board]
In the above-described embodiment, the second connector 8 is mounted from above with the connector insertion / removal direction along the first substrate 51, but the present invention is not limited to this. You may arrange | position so that it may insert / extract from the left of the inner wall 32 and the other side. Since the left end of the front case 12 is also opened three-dimensionally, the cover member 17 also has better workability when inserted and removed from the left side. However, the power cord 6 is hard and difficult to bend. It will come out to the side and a large storage space will be required. Therefore, as in the embodiment, it is preferable to adopt a configuration in which it is inserted and removed from the upper side along the substrate.

  In the above-described embodiment, the second connector 8 is attached to the first substrate 51. However, the present invention is not limited to this, and a substrate different from the first substrate 51 and the second substrate 52 is provided. You may attach to a board | substrate. Since it can be arranged at a position different from the height of the first substrate 51 in this way, for example, the substrate to which the second connector is attached is in the same position as in the embodiment, and the first substrate 51 is in a slightly recessed position, The length of the front case 12 in the front-rear direction can be shortened and can be arranged compactly. When the second connector 8 is mounted on the first substrate 51 as in the embodiment, the second connector 8 and the circuit on the first substrate 51 side can be connected with a wiring pattern, and the second inner wall 32 is provided. -The board | substrate which attaches the 2nd connector 8 may be fixed by fixing a board | substrate in the internal space enclosed by the surrounding wall part 12b.

  Further, for example, the second connector 8 may be attached on the second substrate 52 without providing the first substrate 51 outside the second inner wall 32. In that case, the connector insertion / removal direction may be set to a direction orthogonal to the substrate surface of the second substrate 52.

[Modification of cover member]
In the embodiment, the cover member 17 is formed integrally with the housing, but may be formed as a separate member and attached to and detached from the housing. The case integrated with the housing as in the embodiment is preferable because the cover member 17 is not lost. For example, if the cover member is a separate member, the user attaches and detaches the connector with the cover member removed from the housing in order to perform the attachment and detachment work of the connector, and then attaches the removed cover member to the opening. There is a possibility of losing or losing sight when removed and placed around. In particular, the cover member may be sized according to the size and shape of the opening. In this way, the cover member tends to be small and easily lost. Further, as in the embodiment, the apparatus is preferably used for in-vehicle use, and as such an installation position of the in-vehicle apparatus, for example, it may be arranged below the floor in the vehicle interior. In such a place where the apparatus is installed at a lower position where it is difficult to attach and detach the connector, the user concentrates on the attachment and detachment of the connector, so that the cover member temporarily placed in the surrounding or other places You may not be able to find it. Further, for example, if the size of the cover member is reduced along with the size of the opening, the work of attaching and detaching the housing of the cover member which is a separate member becomes complicated. Is preferably configured.

  In the above-described embodiment, the cover member 17 covers the entire opening 3a, but may cover a part thereof. What covers a part in this way is the same as that formed by another member.

  When the cover member 17 is configured to cover a part of the opening 3a, the first connector 7 and the second connector 8 are preferably configured not to come out of the housing 3 in a state where the cover member 17 is partially covered. For example, the configuration in which the region that is not covered by the cover member 17 in the opening 3a and is open is connected to the first connector 7 and the second connected in the state where the outside of the housing 3 is not exposed. It is preferable that the width and dimensions are such that the connector 8 cannot pass. By covering with the cover member 17, for example, the first connector 7 and the second connector 8 in a connected state are prevented from coming out of the housing 3 when the power supply device 10 is used, and the user accidentally It is possible to prevent the connector 7 and the second connector 8 from touching and coming off.

  In addition, the first connector 7 and the second connector 8 may be prevented from coming out of the housing 3 without covering the opening 3a with the cover member 17. It is preferable that at least one of the second connectors 8 can be positioned outside the housing 3. In this way, the cover member 17 can be removed from the opening 3a, and at least one connector can be positioned outside the housing 3 without covering the opening 3a. good. As a configuration that can be positioned outside the housing 3, for example, the length of lines other than the wiring pattern connected to the connector such as a power cord is lengthened, and the first connector 7 and the second connector 8 are placed in the housing. It may be located outside of 3. In this way, for example, the user can easily perform the attaching / detaching work with the first connector 7 and the second connector 8 being located outside the housing 3, and after the attaching / detaching work, the first connector 7. The second connector 8 can be housed in the housing 3.

[No cover member]
In the embodiment described above, the cover member 17 is provided, but the cover member is not necessarily provided. The state in which the cover member is not present and the connector is exposed is not good in appearance, and dust or the like also enters the housing 3, so that the cover member 17 is preferably provided as in the present embodiment. Further, it is preferable that the cover member 17 is provided so that the first connector 7 and the second connector 8 are housed inside the cover member 17 with the cover member 17 closed regardless of the connection state of the connector.

  In the above-described embodiment, the second connector 8 is directly attached to the substrate. However, in the present invention, the second connector 8 is not necessarily attached directly to the substrate, and may be connected via a cord. In such a case, it is preferable that the cord is made long and the first connector and the second connector are attached and detached while being taken out of the housing, and then pushed into the housing for storage. In this way, it is sufficient that the attaching / detaching work can be performed in a wide space outside the housing. However, in such a configuration, the length of the cord becomes long, and a long space for storing the cord is required when it is housed in the housing. Therefore, it is preferable that the cord is connected to the board as in the embodiment.

[Magnetic shielding function]
In the embodiment described above, the spacer member 53 is also used as a heat dissipation function. However, the present invention is not limited to this, and a magnetic shielding function may be provided instead of the heat dissipation function or in addition to the heat dissipation function.

  For example, a magnetic field generation source such as a coil element is disposed on at least one of the opposing surfaces of the plurality of substrates, and the spacer member 53 is disposed so as to surround the periphery of the magnetic field generation source. For example, as shown in FIG. 23 and the like, when the hole 53a is formed in the spacer member 53, the back surface of the first substrate 51 or the second substrate 52 that faces the first substrate 51 or the second substrate 52 so that the magnetic field generation source is located in the hole 53a. To place. If the spacer member is made of a magnetic material, a closed magnetic path is formed by the spacer member 53 surrounding the magnetic field generation source, and the magnetic field does not leak from the side surface of the spacer member 53 to the outside. The perimeter is preferably the entire perimeter of the four sides. In particular, if the perimeter is surrounded, the spacer member 53 may be composed of a single member having a hole 53a as in the embodiment, for example.

[USB terminal]
In the above-described embodiment, a voltage of 12V is output as the output terminal unit 21 and power is supplied to the in-vehicle device. However, a USB terminal unit may be provided and a function of 5V output may be provided. When the USB terminal is provided, a large amount of heat is generated at the time of output, so that the performance of the battery is deteriorated. Therefore, the USB terminal is not provided as in the embodiment.

[Connector is not connected at the time of shipment]
In the above-described embodiment, the example in which the connector is removed when the user does not use the device for a long time has been described. However, it is preferable that the first connector 7 and the second connector 8 are removed at the time of shipment. Thus, by removing both connectors at the time of shipment, the power consumption of the battery can be suppressed until the user goes to hand. For example, when it becomes a long-term stock, the influence of dark current cannot be ignored, and for example, the battery voltage may drop to a state where it cannot be charged, resulting in an initial failure. By removing it at the time of shipment, the occurrence of such a situation can be suppressed. In this way, when selling with the connector removed at the time of shipment, the user first connects the connector in order to be able to supply power to a device such as a drive recorder.

[Other configurations]
It is preferable that the cover member 17 can be closed even when the connector is removed. The space closed by the cover member 17 has a space for storing the first connector 7 and the second connector 8 in the removed state. If the cover member is left open, dust may enter the housing 3, and something may be caught on the opened cover member. There is also. Therefore, if the cover member can be closed even when the connector is detached, such a problem does not occur because the cover member is closed except for the attaching / detaching operation of the connector.

  In the above-described embodiment, the cushion 22 provided in the storage unit 16 of the battery 1 is provided on the upper surface side, but the installation location and the number of installations are arbitrary, and various correspondences can be taken. For example, the configuration of the embodiment is preferable because the configuration is simple and the sag is not likely to occur due to long-term use because it is sufficient for a vehicle-mounted device if the vibration is about 3G at the maximum. On the other hand, for example, when used in a place where vibration of about 7 G or more is large, the holding force is not sufficient if only one piece is positioned on the upper surface side, and the battery 1 moves inside the housing 3, so that the battery 1 Since the heat-shrinkable tube 5 may be broken, in order to suppress the movement, the size of the cushion may be increased or provided on the lower side.

  Since the connection between the main case 11 and the rear case 12 is firmly coupled from the lateral direction by fastening the nut 14 and the bolt, for example, the main case 11 and the rear case 12 are not detached even when installed in a place where a large vibration of 7G or more occurs. On the other hand, in the case of installation in a place where vibration of about 3G such as in-vehicle is generated, for example, a connection by fitting a projection such as a claw piece and a recess may be used without using such bolts and nuts. With this configuration, the structure is simple and the attachment / detachment is easy. However, it is preferable to fix with bolts and nuts from the side as in the present embodiment, because the apparatus can be used and accommodated for installation of a large vibration generating place without increasing the size of the apparatus.

  In the embodiment described above, the light emitting unit 21 is configured such that the light from the LED 56 provided on the first substrate 51 reaches the fourth opening 12f provided in the front case 12 via the light guide path and emits light there. For example, a light emitting source such as the LED 56 may be arranged near the fourth opening 12f so that light is emitted from the fourth opening 12f.

  In the embodiment described above, the circuit unit 2 includes a plurality of circuits such as a charging circuit and a voltage monitoring circuit. In the case of a plurality, the target from which the current from the battery 1 does not flow by removing the first connector 7 and the second connector 8 may be a part of the plurality of circuit parts, but as in the embodiment, The circuit portion is preferable because it can more effectively suppress the remaining capacity of the battery 1 from decreasing.

  In the embodiment described above, the case main body 11 has a cylindrical shape, and the portion surrounding the entire circumference of the battery 1 is integrated. This is preferable because the battery 1 can be stored and held firmly. In this way, it is preferably formed in a cylindrical shape, but the configuration of the case main body is not limited to this, and for example, a configuration may be adopted in which the battery is sandwiched between a plurality of parts such as upper and lower divisions. For example, when the power supply apparatus 10 is configured to be used in a place where vibration is large, an embodiment in which the battery 1 is securely stored and held is preferable.

  In the above-described embodiment, a secondary battery is used as the battery 1, but it may be a primary battery. If it is a secondary battery, it will suffice if it can charge, and it is good to comprise so that the battery 1 may be charged especially by receiving electric power supply from the battery of a vehicle like embodiment. According to the embodiment, for example, the battery 1 may be charged while the vehicle is running.

  Moreover, although the device of the present invention is a power supply device, it is not limited to a power supply device, and includes, for example, devices such as electric and electronic devices that operate using the power of a battery built in the device. This type of device such as an electric device or an electronic device can be preferably applied to a device having a circuit unit that consumes power by flowing current from a built-in battery even when the power of the device is OFF.

  As described above, the power supply device 10 of the present embodiment receives power supplied from the vehicle battery and supplies power to external devices based on the charging circuit that charges the internal battery 1 and the power supplied from the vehicle battery. Power output circuit and the like. The power output circuit may be configured to supply power to an external device based on the power supply from the vehicle battery regardless of the connection status of the first connector 7 and the second connector 8. In this way, even if the user forgets to remove the first connector and the second connector, the vehicle can be powered and driven during normal running with the engine turned on.
