Description

  The present invention relates to a tilt vibration sensor capable of detecting a plurality of tilt directions and vibrations, and in particular, a switch operates in conjunction with the tilt vibration sensor to perform display switching or in a tilt vibration state. The present invention relates to a portable device or the like that detects levels in stages.

  Conventionally, when switching the display of the combination wristwatch or turning on the backlight of the wristwatch, a switch operation such as pressing a user-specific button has been required. Such a switch operation is difficult and troublesome when the user has a baggage or the like in one hand. Further, in a small portable device, a space required for the switch button is generated, which is an obstacle to further miniaturization. Therefore, portable devices have been proposed that have the function of detecting and detecting the switch just by tilting. (For example, Patent Document 1)

  The tilt vibration sensor for detecting the tilt used in such a switch includes a fixed contact piece made of an elastic member and four fixed electrodes made of a metal member made of a pair of tongue pieces, and the space depending on the direction of gravity. A tilt switch technique is disclosed in which a multi-directional tilt is detected based on an electrical connection position between the four fixed electrodes by contact with a conductive ball that moves freely. (For example, Patent Document 2)

  In addition, there are acceleration sensors using the MEMS technology as sensors that detect tilt vibrations, etc., but since the minute weight is supported by a fine pattern, it is damaged by a drop test, etc., and it is vulnerable to strong impact. In addition, since the distortion of the fine pattern connected to the weight is taken out as a weak voltage by the piezoelectric effect and then amplified by the amplifier, the power consumption is on the order of mW. It is.

  On the other hand, a brass electrode surface and a negative electrode surface are alternately arranged in a skewer shape on a conductive ball and a disk-shaped substrate, and a positive electrode surface and a negative electrode are formed by rolling the ball. A sensor technology for detecting vibration by short-circuiting a surface via a resistor is disclosed. (Patent Document 3)

JP 2004-7334 A (2nd page, FIG. 2) JP 2003-77377 A (page 4, FIG. 4) JP 2000-149737 (page 6, FIG. 1)

  However, Patent Literature 2 establishes an electrical connection by contacting four fixed electrodes made of a metal member in which a fixed contact piece and a tongue piece are paired with a conductive sphere that freely moves in the space according to the direction of gravity. In this method, the connection stability of the conductive sphere is regarded as important, and it is difficult to realize a speedy movement of the conductive sphere by sandwiching the conductive sphere between the fixed contact piece made of an elastic member and the tongue piece. For this reason, it is unsuitable as a switch which operates by a light inclination of a small portable device. In addition, the above method increases the number of components and the components of the fixed electrode are complicated, leading to an increase in the size of the switch.

  Further, since the sensor used in Patent Document 3 is a simple conduction switch, it can detect vibration with low power consumption. However, since the detection level has only two stages, ie, presence or absence of vibration, it is difficult to adjust the operation level depending on the surrounding vibration state for use in a security system or the like.

  The tilt vibration sensor of the present invention includes a substrate having a plurality of individually insulated electrode patterns and a conductive cap. The substrate and the conductive cap are arranged so that the plurality of electrode patterns and the conductive cap face each other, and the conductive vibration sensor is provided. An inclination vibration sensor that detects an inclination direction or vibration by disposing a conductive sphere in a space between a cap and a substrate, and the conductive sphere electrically connects the electrode pattern and the conductive cap. A dummy pattern having a thickness substantially equal to that of the electrode pattern is disposed between the matching electrode patterns.

  Further, the substrate and the conductive cap are characterized in that an end portion of the conductive cap is fitted into a groove portion disposed on the substrate, and the substrate and the conductive cap are integrated. In addition, an external electrode pattern is provided on the surface of the substrate opposite to the surface on which the electrode pattern is formed, and a through hole is provided in the substrate to electrically connect the electrode pattern and the external electrode pattern. It is characterized by.

  In addition, a conductive material is connected to the outer surface of the conductive cap, and the conductive material is disposed so as to extend to the side of the substrate on which the external electrode pattern is formed, and the conductive cap and the conductive material are electrically connected. An electrical signal is applied to the conductive cap by being connected. Alternatively, the conductive cap has a protruding portion in which a part of the conductive cap extends, and is disposed so as to extend on the surface side of the substrate on which the external electrode pattern is formed, and the conductive cap is interposed via the protruding portion. An electrical signal is applied to the device.

  In addition, the four corners of the substrate are each cut into an arc shape, and the external electrode pattern is led out to the four corners on the surface side where the electrode pattern is formed along the side face cut into the arc shape, and the external electrode pattern led to the four corners Thus, an electrical signal is applied to the electrode pattern.

  Further, an integrated circuit chip is mounted on a substrate in a region outside the portion where the conductive cap is fitted. The integrated circuit chip includes a circuit portion for processing a signal, an RS flip-flop circuit, an oscillation circuit, and a counter circuit.

  Furthermore, it is arranged to be inclined with respect to the horizontal direction, and includes means for acquiring level information of the tilt vibration state by an electric signal output from the electrode pattern within a predetermined period. Moreover, such a tilt vibration sensor can be employed in a portable device or a security system.

  By using the tilt vibration sensor of the present invention, it is possible to reduce the size of the switch by reducing the number of parts and the size of the switch by simplifying the circuit configuration by reducing the wiring space. Can be provided. Furthermore, since the conductive ball that performs the switching operation moves freely and smoothly, various operations can be switched even in a wide variety of operations, and a highly functional tilt switch can be provided without a button switch.

  In addition, since it has low power consumption, it can operate even with battery drive. Furthermore, the level of the tilt vibration state can be detected in stages. In addition, the tilt vibration state can be transmitted by radio wave, and the tilt vibration sensor is small, so that a compact tilt vibration detection device can be provided.

The tilt vibration sensor of the present invention will be described in detail. FIG. 1 shows a tilt vibration sensor and a mechanical switch unit of the present invention. 1B is a transmission plan view, and FIG. 1A is a cross-sectional view taken along the line AA ′ of FIG. The external size of the mechanical switch unit is a small size of 3 mm in length, 3.5 mm in width, and 1.3 mm in height.

  In FIG. 1, on the upper surface of the substrate 15 which is a glass epoxy substrate having a thickness of 0.4 mm, four electrode patterns 13 having a thickness of 2 μm plated with gold on a copper foil and a dummy pattern 14 having the same thickness are arranged. ing. In addition, four external electrode patterns having a thickness of 2 μm are formed on the lower surface of the substrate 15 by gold plating on the copper foil. The electrode pattern 13 and the external electrode pattern are electrically connected to each other through a through hole 17. The distance between the electrode patterns 13 is about 0.4 mm, and the width of the dummy pattern 14 arranged between the electrode patterns is about 0.16 mm.

  A groove 16 having a depth of 0.2 mm and a width of 0.2 mm is formed on the substrate 15 by an NC router. Then, an iron plate having a thickness of 0.1 mm is formed into a cap shape by press working, and a conductive cap 12 whose surface is gold-plated is fitted into the groove 16 and fixed by an adhesive. In the space between the conductive cap and the substrate, a conductive ball 11 in which an iron ball having a diameter of 0.8 mm is gold-plated is disposed, and configured to roll smoothly and smoothly according to the inclination in the direction of gravity. The four electrode patterns 13 formed on the upper surface and the conductive cap 12 can be electrically connected independently.

  In this way, the conductive sphere 11 rolls due to the inclination, and it is electrically sensed whether one of the four electrode patterns 13 is located on the electrode pattern 13, and the inclination vibration sensor itself is It can be known whether it is inclined in the direction of. Further, since the dummy pattern 14 is formed between the electrode pattern 13 and the electrode pattern 13, the conductive sphere 11 is not in contact with two adjacent electrode patterns 13 at the same time, so that no malfunction occurs and the sensitivity of the tilt vibration sensor is improved. Let In addition, by forming the dummy pattern 14 equal in thickness to the electrode pattern 13, smooth and speedy movement of the conductive sphere 11 can be realized.

  In this embodiment, the dummy pattern 14 is formed of a conductive material, but may be formed of an insulating material. By forming with an insulating material, it is not necessary to consider the distance between the electrode pattern 13 and the dummy pattern 14, and alignment when forming the dummy pattern 14 is facilitated.

  FIG. 2 illustrates an example of a shape used when the mechanical switch unit of FIG. 1 is reflow-mounted using a solder ball or the like on a mother board of an electronic watch or various portable devices. And FIG. 2B is an external view of the camera viewed from a 90 ° direction. On the outer surface of the conductive cap 21 fixed to the substrate 22 and subjected to gold plating, a ground electrode 23 made of a conductive material made of nickel pieces is fixed by resistance welding. The ground electrode 23 is disposed along the end of the substrate 22 so as to extend to the surface side of the substrate 22 where the external electrode pattern 24 is formed, that is, to the lower surface of the substrate 22. And are electrically connected. The conductive cap 21 and the ground electrode 23 are made of gold and nickel, respectively, and have a slight resistance difference at the joint due to the dissimilar metals. It melts sufficiently and a firm connection is possible.

  Next, another embodiment of the tilt vibration sensor having another shape will be described in detail. FIG. 3 is an exploded view of the mechanical switch portion of the tilt sensor of the present invention. FIG. 3A is a view of the conductive cap 32 as viewed from the side, and has a protruding portion in which a part of the lower portion of the cap extends. The conductive cap 32 is formed by pressing a 1 mm thick copper plate and subjected to gold plating. The length of the protruding portion of the protruding portion is 0.2 mm, and the height of the conductive cap 32 excluding the protruding portion is 1.2 mm.

  FIG. 3B shows a conductive sphere 31 disposed in a space portion fitted with the substrate 35 fitted so as to face the conductive cap 32. The substrate 35 has a structure in which a part of one side is lacking in a concave shape and can be easily fitted to the protruding portion of the conductive cap 32. Further, the four corners of the substrate 35 are cut out in an arc shape, and the external electrode pattern 34 formed on the back surface along the side surface cut out in the arc shape is led out to the surface. When the external electrode pattern is led to the surface along the arc-shaped side surface thus cut, the surface of the external electrode pattern can be widened when mounted on another substrate at the arc-shaped portion. The effect that it is easy to connect is acquired. Furthermore, the electrode pattern with which the conductive sphere 82 is in contact with the metal film formed on the inner surface of the through hole 37 is electrically connected to the external electrode pattern disposed on the back surface of the substrate 83.

  FIG. 3C is a diagram showing the back surface of the substrate 35, and an almost entire surface of the external electrode pattern is covered with an insulating cover lay 39. The external electrode patterns 34 are exposed at the four corners of the substrate 35. Then, as described above, the external electrode patterns 34 at the four corners are led to the four corners of the surface shown in FIG. 3B by the metal film formed on the side surface cut out in an arc shape.

  FIG. 4 shows a view in which the tilt vibration sensor shown in FIG. 3 is mounted on another mounting board. FIG. 4A is a side view of the tilt vibration sensor 41 and the mounted substrate 40 on which the tilt vibration sensor is mounted by surface reflow. A cover lay 49 is disposed on the back surface of the tilt vibration sensor where the mounted substrate 40 and the tilt vibration sensor 41 are in contact. Solder paste 48 is disposed on the electrode pattern 45 formed on the mounting substrate 40, and as shown in FIG. 4B, the aligned external electrode pattern 44 and the electrode pattern 45 of the mounting substrate 40 Are connected with solder 48. The solder was melted in a 40 ° reflow mounting furnace to form a pellet-shaped solder 48, covering the entire external electrode pattern 44, and a firm and highly reliable mounting was possible.

  Next, an embodiment in which the tilt vibration sensor of the present invention is used as a tilt switch will be described in detail. FIG. 5 is a schematic diagram of a switch 51 using the tilt vibration sensor of the present invention. The mechanical switch unit 52 has the configuration illustrated in FIGS. 1 to 3. An IC chip 54 of an integrated circuit chip that is electrically connected to the mechanical switch unit 52 and processes signals is mounted on a substrate in a region outside the portion where the conductive cap of the mechanical switch unit 52 is fitted. Yes. In this embodiment, the IC chip 54 is mounted on the board on which the mechanical switch unit is fitted. However, as shown in FIG. 5, not the fitted board but the mounting board on which the mechanical switch unit is mounted on another board. An IC chip may be mounted on.

  On the board surface opposite to the side where the IC chip 54 is mounted, input / output pads 53 necessary for mounting the switch 51 on another motherboard are arranged. The planar size of the switch 31 is 3 mm long and 4.5 mm wide. Within one second from the arrangement of +20 degrees or more with respect to the horizontal direction as shown in FIG. 5 (a), it is tilted by −20 degrees or more with respect to the horizontal direction as shown in FIG. 5 (b). When tilted by +20 degrees or more like this, a display switching on signal is generated from the output pad.

6A is a schematic plan view of the switch, and FIG. 6B is a cross-sectional view taken along the line BB ′ of FIG. 6A. The function of the mechanical switch unit will be described with reference to FIG. The IC chip 64 electrically connected to the mechanical switch unit 60 processes the connection position of the conductive ball 62, chattering processing, and movement time signal. For example, when the switch is tilted, the conductive ball 62 is positioned at the electrode pattern 65-A, and is sandwiched between the electrode pattern 65-A and the conductive cap 61, and each is made conductive. The IC chip 64 performs chattering processing for storing the electrical continuity state. Conductive ball 62 is 2m
Since it is light as g, it may become non-conductive immediately after conduction, but since the chattering process is performed in this way, it is possible to know exactly which electrode pattern 65 the conductive sphere 62 is connected to, Prevents malfunction as a tilt vibration sensor. Of the electrode pattern 65-A, electrode pattern 65-B, electrode pattern 65-C, and electrode pattern 65-G, the electrode pattern 65-G is electrically connected to the conductive cap 61 in this embodiment. , Connected to 0 V to be a ground electrode (Gnd).

  FIG. 7 is a circuit system diagram around such a switch. The electrode pattern 65-G illustrated in FIG. 6 that is electrically connected to the conductive cap corresponds to the point G of the mechanical switch unit 70 in FIG. 7, and includes the electrode pattern 65-A, the electrode pattern 65-B, and the electrode pattern 65. Similarly, -C corresponds to points A, B, and C of the mechanical switch unit of FIG. The conductive sphere is electrically connected to any one of the electrode pattern 65-A, the electrode pattern 65-B, and the electrode pattern 65-C according to the inclination direction, and is subjected to chattering processing by the RS flip-flop circuit in the IC chip 71, and finally conductive. Is stored at the electrode positions of A, B, and C. The oscillation circuit and the counter circuit make a reference time for the switch to be operated within a predetermined period, and the control circuit controls the conduction order and the time of each point of A, B, C where the switch operates. The conduction order and time are determined by inputting the time input signal 72 and the operation mode input signal 73 from the time input circuit and the operation mode input signal circuit via the external input pad terminal, respectively.

  When the switch operates as described above, the display mode signal 74 or the display switching signal 75 is sent from the IC chip 71 to the LCD segment module 76 so that the time display, the date display, the year display, and the display on the LCD segment module 76 are switched. To the drive circuit.

  The function of an electronic wrist watch that is a small portable device using this switch will be described below with reference to FIG. As shown in FIG. 8 (a), in a combination wristwatch 81 having both an analog watch and a display unit, the arm is tilted inward by 20 degrees or more with respect to the horizontal direction and within 20 seconds within 20 seconds. Tilt and return to the original state, 10:02:36 of the time “10:02:36”, Sunday, April 3 (Sunday) “04: 03: SU”, year display 2007 The display switches cyclically in the order of “20: 07: YE”. Further, as shown in FIG. 8B, when the arm is raised, the arm is tilted to the front within 1 second, further tilted outward, and tilted forward to change the display mode to “time-month-day-year”. The display mode is switched cyclically to the “display mode 80” and the “plural password” display mode 81. In this way, by using the tilt vibration sensor to detect the tilt direction within one second, the display of the hour, minute, second, month, day of the week, and year was smoothly performed on the LCD display.

  FIG. 9 is another electronic wristwatch using the tilt vibration sensor of the present invention as a switch. The timepiece 91 is an analog type electronic wristwatch that drives the long hand 93 and the short hand 92 with one motor and the second hand 94 with a second motor. The dial 95 is printed with “MON, TUE, WED, THU, FRI, SAT, SUN” so that the day of the week can be indicated by the second hand 94. When the watch 91 is in a state where the arm is raised, when the arm is tilted forward within one second, further tilted outward, and then returned to the front, the display of “month / day and day display mode” is displayed from “time display mode”. On January 14 (Wednesday), the long hand (date), the short hand (month), and the second hand (day of the week) are cyclically switched.

  If the display is switched for the first time when a plurality of inclined states are continuously operated within a period shorter than the first inclined period after the initial inclined state is maintained for a certain time of about 1 to 2 seconds, We were able to eliminate almost all unexpected malfunctions. In addition, when applied to a radio-controlled watch, the crown and button switch can be eliminated, resulting in a thin and highly designed electronic watch.

In addition, by additionally arranging the IC chip of the tilt vibration sensor of the present invention in the driving IC of the electronic wristwatch, it is possible to further reduce the number of IC parts and further reduce the size of the watch substrate. Needless to say, the tilt vibration sensor of the present invention can be used not only for an electronic wristwatch but also for a wide variety of small devices and portable devices.

  Next, an embodiment in which the tilt vibration sensor of the present invention is used as a tilt vibration detection device will be described in detail. FIG. 10 is a schematic cross-sectional view showing a tilt vibration sensor 103 incorporated in the tilt vibration detection apparatus. The tilt vibration sensor 103 is mounted on one side surface on an FPC (flexible printed circuit) 102, and the other side surface is mounted on a mother substrate 106. The tilt vibration sensor 103 is disposed on a gradient chip 105 made of brass and tilted with respect to the horizontal direction. By inclining and arranging in this way, the position of the conductive sphere 14 in the inclination vibration sensor 13 is always arranged at a fixed position by gravity. The MPU (microprocessor unit) 101 performs a function of detecting the position where the conductive ball 14 moves due to vibration or tilt and calculating the number of chattering times due to the vibration, and extracting the vibration tilt state as a digital signal.

  The tilt vibration sensor 103 illustrated in FIG. 10 can use the tilt vibration sensor previously illustrated in FIGS. 1 to 3. The external size of the mechanical switch portion which is the tilt vibration sensor is 3 mm in length and 3.5 mm in width. Small size with a height of 1.4 mm.

  FIG. 11 is a schematic explanatory diagram illustrating the inclination vibration sensor in the inclination vibration detection apparatus illustrated in FIG. 10, the conductive ball in the inclination vibration, and the mounting angle of the inclination vibration detection apparatus. On the substrate 111, four independent electrodes A116, B113, C115, and D112 are arranged. According to an experimental result in which the mounting angle 114 is set to 5 degrees with respect to the horizontal plane with respect to the substrate 111, the conductive ball 117 is always disposed on the electrode A116 by gravity. When slight vibration occurs due to the external environment, the conductive sphere 117 vibrates within the range of the electrode A116. However, as the vibration level increases, the conductive sphere 117 contacts the electrode B113 and the electrode C115, and chattering occurs. Further, when the intense vibration or the inclination vibration detector is completely inclined, the conductive sphere 117 comes into contact with the electrode D112 to cause chattering. When the tilt vibration sensor is arranged at an angle in this manner, sensitivity is improved by increasing the area of the electrode D112 located above and narrowing the electrodes A116, B113, and C115 located below. It was. From these results, it became possible to detect the tilt vibration level in stages as follows.

・ Still state: No chattering at the position of electrode A ・ Fine vibration: Chattering at the position of electrode A ・ Medium vibration: Chattering at the position of electrodes A, B, C ・ Strong vibration: Chattering at position

  FIG. 12 shows an example of a crime prevention system using such a tilt vibration detection device. The tilt vibration detection device 123 disposed in the noble metal showcase 104 is configured to receive a buzzer with a reception control function according to the tilt vibration level when the tilt vibration occurs due to damage to the noble metal showcase 124 at night. Radio waves are transmitted to the device 121. For example, when a slight vibration is detected, the video camera 122 is activated, and when a larger vibration or tilt is detected, the radio wave is transmitted again to the buzzer device 121 with a reception control function to generate an alarm buzzer sound.

FIG. 13 is an explanatory diagram showing a circuit block of the security system shown in FIG. In FIG. 13, the mechanical switch 131 of the tilt vibration sensor conducts G (Gnd) and each contact A, B, C, D or generates chattering due to the movement of the conductive ball in the tilt vibration state. These series of signals are sent to the control unit 132 and processed by an RS flip-flop circuit that holds the last state of conduction, and the slope state is instantaneously determined. Calculation is performed for each tilt state, and the tilt vibration state is divided into levels in stages and detected in time series. The obtained level information is sent to the radio wave circuit of the radio wave transmission unit 133. Then, a radio wave 134 is transmitted through the transmission antenna.

  The radio wave 134 transmitted from the tilt vibration detection device is processed by the radio wave receiving circuit through the radio wave antenna of the radio wave receiving unit 135. Then, according to the level information of the tilt vibration, the video camera unit 137 operates when the controller unit 136 detects a slight vibration, and the buzzer unit 138 generates an alarm sound when a larger vibration is detected.

  In this way, by using the tilt vibration detection device of the present invention, it is possible to provide a power-saving and small tilt vibration detection device that can be driven by a battery. It became possible to do.

  Next, an embodiment in which the tilt vibration sensor of the present invention is used in another type of wristwatch will be described in detail with reference to FIGS. FIG. 14 is a schematic diagram of a bracelet type wristwatch (hereinafter referred to as a breath watch) 140. The breath watch 140 is configured by embedding two movements in the breath watch 140. One is a radio wave movement with a second hand 141 with only a second hand, and the other is a radio wave movement with an hour and minute hands 142 with only an hour hand and a minute hand. The radio wave movement 142 with the second hand includes the tilt vibration sensor of the present invention for detecting the direction of the arm and an MPU (microprocessor unit) for analyzing and processing a plurality of arm movements. Is configured to control.

  FIG. 15 is a conceptual diagram showing the operation of the above-described breath watch. The standard time radio wave 159 emitted from the radio tower 150 is received by a radio wave movement circuit 151 with a second hand and a radio wave movement circuit 152 with an hour hand and a minute hand, respectively, and gives an accurate time to each movement. At this time, as shown in FIG. 14, in the radio wave movement 141 with a second hand, the second hand always indicates the day of the week “SUN ·· WED...” Contributes to luxury, fashion and design.

  On the other hand, when a user wants to know the exact time in seconds when using public transport such as a train, the radio wave movement circuit 151 with a second hand is activated by a specific arm movement, and the radio wave movement with a second hand is displayed in seconds. do. For example, in the radio wave movement with a second hand, the mechanical switch unit of the tilt vibration sensor of the present invention and the MPU are arranged as the detection circuit 153, and a plurality of arm movements are performed within a predetermined period. The tilt vibration sensor detects the number and magnitude of tilts, and a signal is sent to the circuit 151 of the radio wave movement with a second hand. Then, the second hand of the radio wave movement with the second hand is operated, and the second hand indicates the second time accurately. The second hand of the radio wave movement with the second hand returns to the day of the week instruction again after a few minutes, such as by timer processing. Furthermore, even when the second hand is stopped and the day of the week is instructed even within the timer processing time, a specific arm motion may be performed again. Here, the detection circuit 153 is provided in the radio wave movement with a second hand, but may be arranged in a separate part.

  As the specific arm movement, the movement described in the first embodiment can be adopted. After raising the arm, tilting the bracewatch toward you, then tilting it to the opposite side and then tilting it toward you again is possible, but depending on the MPU program, another elegant wrist movement is possible. In addition, if a solar cell type movement is used for the radio wave movement, it is possible to provide a high-quality fashion bracelet watch that does not make the watch feel like no battery replacement, no switch or crown.

Since the sensor of the present invention can be driven by a battery, low power consumption can be realized and it can be employed in a small portable device. In addition, it can be applied to crime prevention systems and anti-theft systems by applying this, and can be used in various fields such as home use, office use, and industrial use.
