In recent years, new energy automobiles have been developed dramatically, and in the field of electric automobiles, batteries play an important role as a power source of the electric automobiles. The battery is used as a core part of the new energy automobile, and has higher requirements on safety and cycle service life.

The inventor finds that when the battery is mounted on the vehicle, the connecting structure is often in a region which is difficult to operate, for example, the battery is mounted at the bottom of the vehicle, the disassembly and assembly operation are difficult to perform due to the small ground clearance, or the connecting structure between the battery and the vehicle is difficult to perform the disassembly and assembly operation, so that a power exchange station for power exchange needs to be preset with a groove or the vehicle needs to be lifted, or special tools are needed to operate, and the power exchange difficulty is high, the efficiency is low, and the cost is high.

Based on this, the inventor has conducted intensive studies to design a power conversion system for detachably mounting the battery 1 to the vehicle 1000, connecting the battery 1 to the vehicle 1000 through the locking assembly 2, and driving the locking assembly 2 to lock and/or unlock through the driving member 50, so as to facilitate the disassembly and assembly of the battery 1 on the vehicle 1000, and the setting position of the locking assembly 2 is more flexible, so that the requirements of different installation space dimensions, ground clearance height and the like can be satisfied, the power conversion difficulty is reduced, the power conversion efficiency is improved, and the cost is reduced.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a vehicle 1000 according to some embodiments of the application. The vehicle 1000 may be a fuel oil vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or a range-extended vehicle. The battery 1 may be used for power supply of the vehicle 1000, for example, the battery 1 may serve as an operating power source of the vehicle 1000. The vehicle 1000 may also include a controller and a motor, the controller being used to control the battery 1 to power the motor, for example, for operating power requirements during start-up, navigation and travel of the vehicle 1000. In some embodiments of the application, the battery 1 may not only serve as an operating power source for the vehicle 1000, but also as a driving power source for the vehicle 1000, instead of or in part instead of fuel oil or natural gas, to provide driving power for the vehicle 1000.

Hereinafter, a power conversion system according to an embodiment of the present application will be described with reference to the accompanying drawings.

As shown in fig. 2 to 5, the power conversion system includes: a locking assembly 2 and a driving member 50. Wherein the locking assembly 2 has a locked state and an unlocked state. In the locked state, the locking assembly 2 is locked for connecting the battery 1 to the vehicle 1000; in the unlocked state, the locking assembly 2 is unlocked such that the battery 1 is separable from the vehicle 1000. The driving member 50 is adapted to be provided on the vehicle 1000 or the battery 1, and the driving member 50 is used to drive the locking assembly 2 to lock and/or unlock.

The driving element 50 is provided on the vehicle 1000 or the battery 1, which means that the driving element 50 may be directly mounted on the vehicle 1000 or the battery 1 or may be indirectly mounted on the vehicle 1000 or the battery 1. For example, the battery 1 may include at least part of the battery body 10 and the locking assembly 2, and the driving member 50 may be mounted to at least part of the battery body 10 or the locking assembly 2; it is within the scope of the present application that the vehicle 1000 may include at least a portion of the body, the side sill 200, and the closure assembly 2, and that the driver 50 may be mounted to at least a portion of the body, the side sill 200, or the closure assembly 2.

In the above embodiment, the locking manner of the locking assembly 2 may be flexibly set, for example, may be a clamping connection, a threaded connection, an adhesive connection, or the like, and only needs to satisfy the requirement that the battery 1 can be connected to the vehicle 1000 and the battery 1 can be detached. The locking assembly 2 may be provided entirely on the battery 1 and detachably connected to the vehicle 1000; or the locking assembly 2 may be provided entirely on the vehicle 1000 and detachably connected with the battery 1; or alternatively, the locking assembly 2 may be partially disposed on the battery 1 and partially disposed on the vehicle 1000, and the two parts may be detachably connected to each other to enable the battery 1 to be mounted on and dismounted from the vehicle 1000.

For example, in some embodiments, as shown in fig. 2-5, the locking assembly 2 includes a mounting structure adapted to be provided on the battery 1 and a connection structure adapted to be provided on the vehicle 1000, the mounting structure being lockable with the connection structure. The mounting structure or connection structure is connected to the driving member 50.

In the locked state, the mounting structure and the connecting structure are locked, and the locking assembly 2 is locked, connecting the battery 1 to the vehicle 1000; in the unlocked state, the mounting structure and the connection structure are unlocked, and the locking assembly 2 is unlocked, enabling the battery 1 to be separated from the vehicle 1000. The battery 1 and the vehicle 1000 themselves need not be improved or only need a small improvement, which is advantageous in reducing the cost.

The driving member 50 may be coupled to the mounting structure and drive the movement of the mounting structure relative to the coupling structure to effect locking and unlocking of the mounting structure and the coupling structure; the driving member 50 may also be coupled to the coupling structure and drive movement of the coupling structure relative to the mounting structure to effect locking and unlocking of the mounting structure to the coupling structure. The driving piece 50 is only connected with one of the mounting structure and the connecting structure, so that the driving piece 50 is prevented from being detached when the battery 1 is separated from the vehicle 1000, and convenience in disassembly and assembly of the battery 1 is improved.

For another example, in other embodiments, the locking assembly 2 includes a mounting structure adapted to be provided on the battery 1, the mounting structure being directly lockable with the side sill 200 of the vehicle 1000, thereby eliminating the need for additional attachment structures on the vehicle 1000 to reduce parts; or the locking assembly 2 comprises a connecting structure which is suitable for being arranged on the vehicle 1000, and the connecting structure can be directly locked with the shell 12 of the battery 1, so that an additional mounting structure on the battery 1 is not needed to be arranged, and parts are reduced.

In the embodiment of the present application, the specific structure of the driving member 50 may be flexibly set, for example, the driving member 50 may be a hydraulic motor, a pneumatic motor, an electric motor, or the like. The hydraulic motor and the pneumatic motor can realize stepless speed regulation, have high response speed and small volume, are convenient to install in a small space area on the battery 1 or the vehicle 1000, and meet various installation requirements.

The driving member 50 is used to drive the locking assembly 2 to lock and/or unlock, i.e. the driving member 50 may be used to drive the locking assembly 2 only, may be used to drive the locking assembly 2 only to unlock, or may be used to drive the locking assembly 2 to lock and unlock. The vehicle 1000 or the driving piece 50 of the battery 1 drives the locking assembly 2 to act, so that the operation of auxiliary tools can be reduced or omitted, the power changing difficulty is reduced, and the power changing efficiency is improved.

The driving member 50 can drive the locking assembly 2 to act, so that the setting position of the locking assembly 2 can be more flexible. For example, may be provided in a small area on the vehicle 1000 or the battery 1; or may be provided between the vehicle 1000 and the battery 1; furthermore, the battery 1 and the vehicle 1000 with smaller ground clearance can be met, and meanwhile, the battery replacing station 2000 for replacing the power does not need to be provided with a groove or the vehicle 1000 is too high, so that the difficulty in replacing the power can be reduced.

According to the power conversion system of the embodiment of the application, the battery 1 is connected to the vehicle 1000 through the locking assembly 2, and the driving piece 50 is arranged for driving the locking assembly 2 to lock and/or unlock, so that the battery 1 can be conveniently dismounted on the vehicle 1000, the setting position of the locking assembly 2 is more flexible, the requirements of different installation space sizes, ground clearance heights and the like can be met, the power conversion difficulty is reduced, the power conversion efficiency is improved, and the cost is reduced.

In the embodiment of the present application, the triggering manner of the driving member 50 can be flexibly set.

For example, the driving member 50 may automatically detect the mounted state of the battery 1 on the vehicle 1000 and automatically drive the locking assembly 2 to be locked or unlocked to reduce the number of parts.

For another example, the power conversion system may include a switch member communicatively coupled to the drive member 50, the switch member being configured to cause the drive member 50 to drive the locking assembly 2 to lock and/or unlock when activated.

Since the driving member 50 needs to be connected to the locking assembly 2, the driving member 50 needs to be disposed close to the locking assembly 2. By arranging the switch piece in communication connection with the driving piece 50, the switch piece can trigger the driving piece 50 through communication, and the arrangement position of the switch piece is not limited by the position of the driving piece 50. Therefore, the switch piece can be arranged at a position which is easier to observe or operate, so that the convenience of electricity replacement is improved.

For example, the switch member may be disposed on an exposed side wall or bottom wall of the battery 1, an exposed wall surface of the vehicle 1000, etc., and the switch member is triggered manually or by an AGV during the power exchange process of the power exchange station 2000, so that the switch member sends a signal, and the driving member 50 directly or indirectly receives the signal sent by the switch member and performs a response action according to the signal, so as to lock or unlock the locking assembly 2.

It should be noted that the communication connection between the switch member and the driving member 50 is not limited. For example, the switch may send electrical signals, optical signals, etc. directly to the driver 50, or the switch may send signals to a control component of the vehicle 1000 that receives the signals and controls the operation of the driver 50 based on the signals.

In some embodiments, the switch member is adapted to be provided on the side sill 200 of the vehicle 1000 such that the switch member is not easily obscured by other structures of the vehicle 1000 or the battery 1 and is thus easily activated. Or, when the battery 1 moves to the bottom of the vehicle 1000, the battery 1 or the AGV carrying the battery 1 can trigger the switch member, and the switch member can detect that the battery 1 moves in place on the vehicle 1000 and automatically make the driving member 50 drive the locking assembly 2 to lock, thereby completing the fixing of the battery 1, and being beneficial to reducing the assembly process. Still alternatively, when the battery 1 needs to be disassembled, the AGV carrying the battery 1 may trigger a switch member that detects the need for disassembly of the battery 1 and automatically causes the driving member 50 to drive the locking assembly 2 to unlock, so as to reduce the disassembly process. In addition, in the embodiment where the switch element and the control component are in communication, the switch element and the control component are both arranged on the vehicle 1000, so that the communication is more convenient. And the switch member does not occupy space on the battery 1, which is advantageous for improving the energy density of the battery 1.

In some embodiments, the switch member is adapted to be disposed outside the recess 13 of the battery 1 for evading the side sill 200 of the vehicle 1000. For example, an end wall provided at an end of the battery 1 in the horizontal direction, a bottom wall of the battery 1, or the like. Thus, the switch is not shielded by the battery 1 or the side sill 200, and the like, facilitating the triggering of the switch. In embodiments where the switch requires power, the switch may be powered by the battery 1 or by other power structures.

In the above embodiments, the specific manner of the switch member is not limited, and may be a micro switch, a button, a laser sensor, or the like.

Wherein, the movable contact and the stationary contact of the micro switch can be contacted and separated to realize connection and disconnection. The driving piece 50 drives the locking assembly 2 to be locked in the on state, and the driving piece 50 drives the locking assembly 2 to be unlocked in the off state; or the driving piece 50 drives the locking assembly 2 to unlock in the on state, and the driving piece 50 drives the locking assembly 2 to lock in the off state; alternatively, the micro-switch is triggered in the on state or the off state, and the driving member 50 drives the locking assembly 2 to lock or unlock in the triggered state. The micro switch has small volume, good waterproof and dustproof functions, sensitive response and contribution to improving the electricity conversion efficiency.

The button is triggered when pressed, and the driving piece 50 drives the locking assembly 2 to be locked or unlocked when triggered; or the button is driven by the driving member 50 to lock the locking assembly 2 when pressed an odd number of times, and the locking assembly 2 is driven by the driving member 50 to unlock when pressed an even number of times. The button has simple structure and control logic, and can reduce cost.

The laser sensor can emit laser, when the laser is shielded, the laser is triggered, and the driving piece 50 drives the locking assembly 2 to be locked or unlocked during triggering; alternatively, the laser is triggered when it is not blocked, and the driver 50 drives the locking assembly 2 to lock or unlock when triggered; alternatively, the driver 50 drives the locking assembly 2 to lock when the laser is blocked, and the driver 50 drives the locking assembly 2 to unlock when the laser is not blocked. The laser sensor can realize that contactless response speed is fast, and the precision is high, and not fragile, long service life.

In some embodiments, the switch member may be continuously activated such that the drive member 50 alternately drives the locking assembly 2 to lock and unlock. Specifically, when the switch member is triggered for the first time, the driving member 50 drives the locking assembly 2 to lock; when the switch element is triggered for the second time, the driving element 50 drives the locking assembly 2 to unlock; when the switch element is triggered for the third time, the driving element 50 drives the locking assembly 2 to lock again; when the switch member is activated for the fourth time, the driving member 50 drives the locking assembly 2 to unlock again, and so on.

It should be noted that, "the side sill 200 is inserted into the recess 13 along the first direction F1" means that: at least a portion of the side sill 200 extends into the recess 13, and not all of the side sill 200 is located within the recess 13. More specifically, the side sill 200 may be a section extending into the recess 13 in the longitudinal direction, and further may be a section partially or entirely extending into the recess 13 in the vertical direction.

The side sill 200 includes two side sills 201 extending in a first direction F1 and arranged in a second direction F2. The battery body 10 is detachably mounted to the side sill 200 by a power exchanging system including the locking assembly 2 and the driving member 50. The locking assembly 2 comprises a first locking assembly 20 and a second locking assembly 30, the first locking assembly 20 comprising a first connection structure 31 and a first mounting structure, and the second locking assembly 30 comprising a second connection structure 32 and a second mounting structure 22. The first connecting structure 31 is a bolt and is arranged between the two longitudinal beams 201, and the driving piece 50 is a hydraulic motor and is connected with the bolt; the second connecting structure 32 is a padlock and is provided on the brackets 40 on both sides of the side sill 200. The first mounting structure is a nut and is provided on the bottom wall of the recess 13 of the battery 1, and the second mounting structure 22 is a locking pin and is provided in the mounting groove 121 at both ends of the battery 1 in the second direction F2. The second connecting structure 32 and the second mounting structure 22 are not provided with the driving member 50 correspondingly.

Therefore, the battery 1 is connected with the first connecting structure 31 and the second connecting structure 32 on the side sills 200 through the first mounting structure and the second mounting structure 22 at two ends in the concave part 13, so that chassis power conversion of the two side sills 201 of the vehicle 1000 is realized, the gravity center of the battery body 10 is positioned below the side sills 201, the gravity center of the battery body 10 is effectively reduced, the stability of the battery body 10 is improved, and a large space is improved for the stability and safety of the vehicle 1000. And has the advantages of compact structure, high space utilization rate (especially space in the vertical direction), and the like.

In the related art, it is necessary to pre-mount the battery on the battery-changing frame and then fix the entire battery-changing frame to the vehicle. Because the battery is pre-installed on the battery replacing frame, the whole battery replacing unit is large and heavy, so that the matched battery replacing AGV needs to be larger and can bear load, and the design is complex; secondly, because the batteries are integrated together, more power exchange frames are needed to bear stress, so that the volume occupied by the power exchange frames in space is larger, the electric quantity of the power exchange system cannot be increased, and the distance between the power exchange stations is limited; thirdly, as the batteries are integrated together to be used as a whole for replacing electricity, the span of the locking points is larger, the deviation between the locking points is also larger, the locking time is prolonged during the electricity replacement, the success rate of the electricity replacement locking is reduced, and the electricity replacement efficiency is greatly restricted. Finally, the battery is integrated into a whole, so that the battery is used as a whole battery replacement unit, one vehicle type can only be matched with one battery, and different application scenes can only be matched with a single battery, so that the flexibility of battery replacement is low, and the product compatibility is poor.

In the application, each battery body 10 is independently mounted to the vehicle bottom longitudinal beam 200 through the first mounting structure 21 and the second mounting structure 22, so that the occupation of the space by the power conversion frame is reduced, the problem of low space utilization rate can be effectively solved, and the energy density of the power conversion system can be improved. Due to the sub-packaging system, different application scenes and vehicle types can be matched with the battery bodies 10 with different numbers, and the size of the battery bodies 10 is further reduced due to sub-packaging, so that the span between mounting structures is reduced, the spacing accuracy of the mounting structures is improved, and the locking success rate is effectively improved.

And the first mounting structure 21 and the first connecting structure 31 are locked and unlocked through the driving of the driving piece 50, and the second mounting structure 22 and the second connecting structure 32 are in a buckling mode, so that the electricity conversion efficiency is greatly improved, and meanwhile, the cost is reduced. And because of the subcontracting system, the volume of the battery body 10 is significantly reduced compared with previous solutions, thereby providing a better solution for both the design of the power change AGV and the design of the power change station 2000.

Further, the first mounting structure 21 is disposed in the recess 13 of the battery body 10, and the second mounting structure 22 is disposed at both ends of the battery body 10 in the second direction F2, so that the strength of the mounting of the battery body 10 with the side sill 200 can be improved. And a plurality of first mounting structures 21 in the concave part 13 are arranged on the bottom wall of the concave part 13, so that the compatibility of the battery 1 can be improved, and the strength loss caused by the addition of the cushion blocks at the locking position can be avoided. In addition, the size of the battery body 10 along the second direction F2 is larger than the size along the first direction F1, the battery body 10 is reduced in size, the span between a plurality of mounting structures is reduced, and the locking precision and the locking efficiency are improved.

In addition, the first locking element 20 and the second locking element 30 are two types of locking elements 2 that are different in kind. The second locking assembly 30 adopts a snap-fit structure. The first locking assembly 20 drills attachment holes for bolts inside the stringers 201 and then secures the hydraulic motor and bolts thereto and communicates with the vehicle. When the power needs to be replaced, the second locking assembly 30 adopts mechanical unlocking, the AGV sends a signal to the whole vehicle end, the whole vehicle end receives the signal and then starts the hydraulic motor, and torque is output, so that the bolt rotates to unlock the nut on the battery 1. And the two types of locking structures are matched, and the locking reliability can be improved under the synergistic effect.

The second attachment structure 32 is integrated with the bracket 40, and the bracket 40 is fixed to the side sill 200 with a hard connection. The second connection structure 32 is fixed in a single-point unlocking structure, that is, the plurality of second connection portions 322 of the second connection structure 32 are linked by links.

The battery body 10 has a special-shaped structure, the middle part of which is provided with a concave 13, and the end part of which is provided with a concave mounting groove 121. The structural form can not only improve the structural strength, but also utilize the space of each position, so that the energy density can be properly improved. Because this structure has all set up connection structure in the middle part and both ends of battery body 10, so the connection of battery 1 and car bottom longitudinal beam 200 further strengthens to effectual promotion trades back battery 1 structural strength. The whole power conversion system is matched and combined by a plurality of batteries 1, and can adapt to different power conversion scenes and vehicle types. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other.

The above is only a preferred embodiment of the present application, and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art.
