Description

Technical Field

[0001] This invention belongs to the field of automotive battery testing technology, and specifically relates to a testing device for testing battery swapping lock bodies. Background Technology

[0002] Battery swapping is a new way to quickly replenish energy in recent years with the rise of the new energy vehicle industry. Compared with fast charging, battery swapping significantly shortens the replenishment time and improves the replenishment efficiency per unit area, making it more suitable for scenarios with rapid replenishment needs and limited space and power capacity.

[0003] Battery packs capable of battery swapping are equipped with battery swapping locks, which allow for the connection or disconnection of the battery pack from the vehicle body. This enables rapid battery pack replacement in new energy vehicles. Therefore, the development of the battery swapping lock and its paired unlocking system is undoubtedly key to the overall development of battery swapping systems for vehicles. Each battery swapping operation involves unlocking the lock for a low-charged battery and locking the lock for a fully charged battery. Unlike non-fast-swap batteries, the locks used to secure fast-swap battery packs require frequent disassembly and reassembly (fast-swap batteries typically undergo approximately 2000-5000 battery swapping operations throughout their lifespan). Combined with the comprehensive durability requirements of fast-swap vehicles under various road conditions, numerous operational factors must be considered during the development of the battery swapping lock.

[0004] Therefore, during the development and iteration of the battery swapping lock body and its paired unlocking system, it is necessary to test the battery swapping lock body to evaluate its durability and other performance characteristics. However, the traditional method of testing the battery swapping lock body involves manual unlocking and unlocking operations, which can easily lead to inaccurate test results and low testing efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of inaccurate test results and low test efficiency in existing methods for testing battery swapping lock bodies.

[0006] To address the aforementioned technical problems, embodiments of the present invention disclose a testing device for testing battery swapping lock bodies. The battery swapping lock body includes a connecting portion and a locking portion. The connecting portion is used to connect to the vehicle body, and the locking portion is used to lock or unlock the connection between the connecting portion and the vehicle body. The testing device comprises: a bracket; a lock body adapter assembly disposed on the bracket and used for detachably mounting the locking portion of the battery swapping lock body under test; and an unlocking / unlocking assembly disposed on the bracket and located below the lock body adapter assembly. The unlocking / unlocking assembly can perform locking and unlocking actions, and includes an unlocking component that is adapted to the locking portion. The unlocking / unlocking assembly can move relative to the bracket along its height direction to adjust the distance between the unlocking / unlocking assembly and the lock body adapter assembly, and allows the unlocking component of the unlocking / unlocking assembly to engage with the lock body adapter assembly. The locking part of the battery swapping lock body under test switches between a connected state and a disconnected state. When the unlocking component is connected to the locking part, the action of the unlocking component can be transmitted to the locking part through the unlocking component, causing the locking part to switch between a locked state and an unlocked state. The body connecting component is set on the bracket and located above the lock body adapter component. The body connecting component can move relative to the bracket along the height direction of the bracket, so that the body connecting component can switch between a first moving position and a second moving position. When the body connecting component is in the first moving position and the locking part is in the locked state, the body connecting component is fixedly connected to the connecting part of the battery swapping lock body under test. When the locking part is in the unlocked state, the body connecting component can move from the first moving position to the second moving position along the height direction of the bracket in a direction away from the lock body adapter component.

[0007] Using the above technical solution, during the testing of the battery swapping lock body under test, when locking, the locking / unlocking component is raised to a high position, and the unlocking component is adapted and connected to the locking part of the battery swapping lock body under test to form a connection state; the vehicle body connection component is lowered to a first moving position; the locking / unlocking component performs a locking action, which is transmitted to the locking part through the unlocking component, causing the locking part to switch to a locked state. The process of the locking part switching to a locked state causes the connection part of the battery swapping lock body under test to change state and be fixedly connected to the vehicle body connection component to achieve locking; when unlocking, the locking / unlocking component is raised from a low position to a high position, and the unlocking component is adapted and connected to the locking part of the battery swapping lock body under test to form a connection state; the locking / unlocking component performs an unlocking action, which is transmitted to the locking part through the unlocking component, causing the locking part to switch to an unlocked state. The process of the locking part switching to an unlocked state causes the connection part of the battery swapping lock body under test to change state and be disconnected from the vehicle body connection component to achieve unlocking; one locking / unlocking test cycle is completed. The testing device provided by this invention can be used to perform durability tests on the battery swapping lock body, as well as repeated disassembly and assembly durability and iterative tests on the battery swapping lock body, and iterative verification of the unlocking process control strategy.

[0008] According to another specific embodiment of the present invention, the testing device disclosed in the embodiment of the present invention further includes a locking / unlocking component, the locking / unlocking component being rotatable about an axis extending along the height direction of the support; the locking / unlocking component is connected to the unlocking component, and the locking / unlocking component is driven to rotate by the locking / unlocking component.

[0009] By adopting the above technical solution, the unlocking component is driven to rotate by a rotating mechanism, thereby driving the locking part of the battery swapping lock body to switch between the locked and unlocked states.

[0010] According to another specific embodiment of the present invention, a testing device is disclosed in which a rotating mechanism is adjustable relative to an unlocking member in a first rotating position and a second rotating position. In the first rotating position, the rotation axis of the unlocking member coincides with the rotation axis of the locking part; in the second rotating position, the rotation axis of the unlocking member is parallel to the rotation axis of the locking part and is separated by a preset distance.

[0011] By adopting the above technical solution, the spatial degree of freedom of the unlocking gun head of the battery swapping station and the stability test of the matching size of the coupling interface with the battery swapping lock body can be realized.

[0012] According to another specific embodiment of the present invention, a testing device disclosed in this embodiment includes a lock body adapter assembly comprising a mounting base, a base, multiple guide pins, multiple adjusting screws, multiple tension springs, and multiple limiting pins. The mounting base has mounting holes for mounting the locking part of the battery swapping lock body, and the mounting base can be detachably connected to the housing of the locking part via fasteners. The base has through holes through which an unlocking component can pass and be adapted to the locking part. The multiple guide pins, multiple tension springs, and multiple limiting pins are uniformly arranged circumferentially between the base and the mounting base, and when the locking part is installed, the multiple guide pins, multiple tension springs, and multiple limiting pins are located on the outer periphery of the locking part. The multiple adjusting screws are matched with the multiple tension springs for adjusting the tension of the tension springs.

[0013] Using the above technical solution, it is possible to test the load-bearing capacity of the battery swapping lock body under extreme conditions when the battery pack and the lower part of the vehicle body are locked due to a fault.

[0014] According to another specific embodiment of the present invention, a test device is disclosed in the embodiment of the present invention, wherein the vehicle body connection assembly includes a mounting plate and a simulated vehicle body lock hole plate; the simulated vehicle body lock hole plate is detachably mounted on the mounting plate by means of fasteners; and when the vehicle body connection assembly is in a first moving position and the locking part is in a locked state, the simulated vehicle body lock hole plate is fixedly connected to the connection part of the battery swapping lock body under test.

[0015] The above technical solution facilitates the replacement of the appropriate simulated vehicle body lock hole plate when replacing the battery swapping lock body under test; at the same time, it can verify the reliability of the battery swapping lock body's unlocking strategy under different vehicle body thicknesses.

[0016] According to another specific embodiment of the present invention, a testing device disclosed in the present invention has two elongated holes on the mounting plate, the two elongated holes being located on opposite sides of a simulated vehicle body lock hole plate, and each elongated hole extending along a first direction, the first direction being perpendicular to the height direction of the bracket; fasteners pass through the elongated holes so that the simulated vehicle body lock hole plate can be mounted on the mounting plate, and the position of the simulated vehicle body lock hole plate relative to the mounting plate along the first direction can be adjusted by adjusting the position of the fasteners in the elongated holes.

[0017] By adopting the above technical solution, it is possible to simulate the test condition of the battery swapping lock body being offset to the limit relative to the vehicle body lock hole, and to conduct a test on the success rate of repeated disassembly and assembly of the battery swapping lock body under the limit deviation of the vehicle body lock hole plate.

[0018] According to another specific embodiment of the present invention, a testing device disclosed in this embodiment of the present invention includes a mounting plate having a through hole, the through hole being matched with the position of the simulated vehicle body lock hole plate and the connecting part; the mounting plate has scale lines on at least one side along a first direction and at least one side along a second direction, the second direction being perpendicular to the first direction and perpendicular to the height direction of the bracket; the simulated vehicle body lock hole plate also has a first adjusting rod and a second adjusting rod, the first adjusting rod extending along the first direction and the end of the first adjusting rod pointing to the scale line in the first direction, the second adjusting rod extending along the second direction and the ends of the second adjusting rod pointing to the scale line in the second direction.

[0019] By adopting the above technical solution, the movement trajectory of the connecting part of the battery swapping lock body can be observed in real time from above during the test through the through hole; and the installation position of the simulated vehicle body lock hole plate can be adjusted according to the alignment position of the end of the adjusting rod with the scale line.

[0020] According to another specific embodiment of the present invention, a testing device disclosed in the embodiment of the present invention further includes a controller, which is connected to a first lifting component, an unlocking component, and a second lifting component, respectively, and is used to control the operation of the first lifting component, the unlocking component, and the second lifting component.

[0021] By adopting the above technical solution, the identification logic of the unlocking component, the unlocking process strategy, and the judgment conditions for successful unlocking can be flexibly configured, which improves the automation of the testing device and makes the operation convenient.

[0022] According to another specific embodiment of the present invention, a testing device disclosed in the present invention further includes a data acquisition module, which is connected to an unlocking / unlocking component and a controller respectively; the data acquisition module is used to acquire relevant parameters of the unlocking / unlocking component and transmit them to the controller; the testing device also includes a screen, which is connected to the controller; wherein the controller, the data acquisition module and the screen are integrated on a single housing to form a control interaction system.

[0043] The quick-swap battery pack includes a battery box and a battery swapping lock body. The battery swapping lock body is an important structure for replacing and securing the battery pack. It enables new energy vehicles to quickly replace the battery pack. Each battery swapping operation involves unlocking the lock body for a low-charged battery and locking the lock body for a fully charged battery. The lock body of the quick-swap battery pack needs to be frequently disassembled and reassembled. Therefore, the design of the battery swapping lock body must ensure its locking security and fatigue durability.

[0044] Therefore, during the development and iteration of the battery swapping lock body and its paired unlocking system, it is necessary to test the battery swapping lock body to evaluate its durability and other performance characteristics. However, the traditional method of testing the battery swapping lock body involves manual unlocking and unlocking operations, which can easily lead to inaccurate test results and low testing efficiency.

[0045] To address the aforementioned problems, this invention develops a testing device for testing battery swapping lock bodies, comprising: a locking part for detachably installing the battery swapping lock body under test, a lock body adapter assembly; an unlocking assembly capable of performing locking and unlocking actions, used to switch the unlocking component of the unlocking assembly and the locking part of the battery swapping lock body under test in the lock body adapter assembly between a connected state and a disconnected state; and a vehicle body connection assembly for simulating a vehicle body.

[0046] When testing the battery swapping lock body under test using the testing device provided by this invention, during locking, the locking / unlocking component is raised to the high position of the bracket, allowing the unlocking member at the upper end to engage with the locking part of the battery swapping lock body under test, which is located in the lock body adapter assembly. This causes the locking / unlocking component to perform a locking action, locking the battery swapping lock body under test. During unlocking, the locking / unlocking component is raised to the high position, and the unlocking member engages with the locking part of the battery swapping lock body under test, performing an unlocking action, unlocking the battery swapping lock body under test. This completes one locking / unlocking test cycle. The testing device provided by this invention simulates the locking and unlocking system in the actual battery swapping process through the locking / unlocking component, enabling early-stage testing of the locking / unlocking process for the battery swapping lock body to ensure its reliability. Furthermore, the locking / unlocking component exhibits high consistency across multiple operations, improving the accuracy of the test results. The testing device automatically completes the testing of the battery swapping lock body, resulting in high testing efficiency and accelerating the development and verification cycle of fast-swap models and locking / unlocking systems.

[0047] To better understand the testing device for testing battery swapping lock bodies provided in this application, the content of the present invention will be described in detail below with reference to the accompanying drawings.

[0048] This invention provides a testing device for testing battery swapping lock bodies. To more clearly explain the testing device, the battery swapping lock body is first described. The battery swapping lock body is mounted on the battery box and includes a connecting part and a locking part. The connecting part is used to connect to the vehicle body, and the locking part is used to lock or unlock the connection between the connecting part and the vehicle body. The locking and unlocking process is achieved through an unlocking / unlocking system paired with the battery swapping lock body (generally located at a battery swapping station). During battery swapping, the unlocking / unlocking gun in the unlocking / unlocking system is inserted into the locking part of the battery swapping lock body to unlock it, thus releasing the fixed connection between the connecting part of the battery swapping lock body and the vehicle body (i.e., the connecting part can be separated from the vehicle body), thereby removing the low-charged battery pack. A fully charged battery pack is placed in the location where the battery pack is located on the vehicle body, and then the unlocking / unlocking gun in the unlocking / unlocking system is inserted into the locking part to lock the battery swapping lock body, fixing the connecting part of the fully charged battery pack's battery swapping lock body to the vehicle body, completing one battery swapping process.

[0049] like Figure 1 and Figure 2 As shown, the test device 10 includes a bracket 11, a lock body adapter component 12, an unlocking component 13, and a vehicle body connection component 14. The bracket 11 is the supporting structure for the entire test device 10. The lock body adapter component 12 is disposed on the bracket 11 and is used for detachably installing the locking part 22 of the battery swapping lock body 20 under test. The unlocking component 13 is disposed on the bracket 11 and located below the lock body adapter component 12. It can perform locking and unlocking actions to lock and unlock the locking part 22 of the battery swapping lock body 20 under test. The vehicle body connection component 14 is disposed on the bracket 11 and located above the lock body adapter component 12. It is used to connect or disconnect from the connection part 21 of the battery swapping lock body 20 under test.

[0050] like Figure 1 As shown, the bracket 11 may specifically include a base plate, columns, etc., and may also include a shielding structure (such as a plate or glass as a side wall) disposed on the outer periphery of the bracket 11. One of the side walls may also be configured as a door, which can be opened to facilitate operation of the components of the bracket 11. In order to facilitate movement, multiple rollers may also be provided at the bottom of the bracket 11.

[0051] The lock body adapter assembly 12 is located at the center of the bracket 11 in the height direction and is used for detachably installing the locking part 22 of the battery swapping lock body 20 under test. Specifically, a support structure (such as a support plate) can be provided in the center of the bracket 11, and the lock body adapter assembly 12 can be installed on the support structure. The lock body adapter assembly 12 should have a through hole. One end of the through hole is used to adapt and install the locking part 22 of the battery swapping lock body 20. The size and shape of the hole only need to be compatible with the outer diameter of the housing of the locking part 22 of various battery swapping lock bodies 20. The other end of the through hole is used to allow the unlocking assembly 13 to operate the locking part 22. The lock body adapter assembly 12 and the battery swapping lock body 20 under test can be connected by means of screws or other methods.

[0052] like Figure 1 As shown, the locking / unlocking component 13 is disposed on the bracket 11 and located below the lock body adapter component 12; the locking / unlocking component 13 can perform locking and unlocking actions. Specifically, the locking and unlocking actions can be achieved by rotation, movement, etc. The locking / unlocking component 13 may include corresponding driving components to realize the locking and unlocking actions. Figure 3 As shown, the unlocking component 13 also includes an unlocking member 131. The structure of the unlocking member 131 is adapted to the locking part 22. That is, the unlocking member 131 is used to simulate the unlocking gun head of the battery swapping station unlocking system. The unlocking member 131 and the unlocking component 13 can be detachably connected so that when different types of battery swapping lock bodies 20 under test are replaced on the lock body adapter component 12, the corresponding unlocking member 131 can be replaced. Specifically, the unlocking member 131 can be set at the upper end of the unlocking component 13 or at the side of the unlocking component 13, depending on the structure and unlocking method of the battery swapping lock body 20 under test, as long as it can simulate the battery swapping process.

[0053] The unlocking component 13 can move (i.e. rise and fall) relative to the bracket 11 along the height direction of the bracket 11 to adjust the distance between the unlocking component 13 and the lock body adapter component 12. It can also switch between the unlocking component 131 of the unlocking component 13 and the locking part 22 of the battery swapping lock body 20 under test in the lock body adapter component 12 in the connected state and the disconnected state, thereby simulating the movement operation of the unlocking system when unlocking. Specifically, after the unlocking / unlocking component 13 is raised, causing the unlocking member 131 to approach the locking part 22 of the battery-changing lock body 20 under test in the lock body adapter component 12; if the locking part 22 and the unlocking member 131 are in corresponding vertical positions, by continuing to raise the unlocking / unlocking component 13, the unlocking member 131 and the locking part 22 can be adapted and connected (i.e., the locking cap is engaged), forming a connected state. Further, by lowering the unlocking / unlocking component 13, the unlocking member 131 can be disengaged from the locking part 22, forming a separated state. If the locking part 22 and the unlocking member 131 are in corresponding horizontal or inclined positions, by moving the unlocking member 131 horizontally or inclined towards the locking part 22, the unlocking member 131 and the locking part 22 can be adapted and connected, forming a connected state. Correspondingly, by reversing the operation, the unlocking member 131 and the locking part 22 can be disengaged, forming a separated state. More specifically, the unlocking / unlocking component 13 can be raised and lowered manually, or a lifting structure connected to the unlocking / unlocking component 13 can be provided to drive the unlocking / unlocking component 13 to rise and fall. In one specific embodiment, such as Figure 1 As shown, the test device 10 also includes a first lifting assembly 15, which is disposed on the bracket 11 and located below the lock body adapter assembly 12. The first lifting assembly 15 is connected to the unlocking assembly 13 and can drive the unlocking assembly 13 to move along the height direction of the bracket 11. When the unlocking component 131 is connected to the locking part 22, the locking and unlocking actions of the unlocking assembly 13 can be transmitted to the locking part 22 through the unlocking component 131, so that the locking part 22 switches between the locked state and the unlocked state; thereby realizing the simulation of the unlocking and unlocking system performing the unlocking and unlocking operation process on the locking part 22 of the battery swapping lock body 20.

[0054] like Figure 1As shown, the vehicle body connecting assembly 14 is disposed on the bracket 11 and located above the lock body adapter assembly 12. The vehicle body connecting assembly 14 can move (i.e., rise and fall) relative to the bracket 11 along the height direction of the bracket 11, so that the vehicle body connecting assembly 14 can switch between a first moving position (below) and a second moving position (above). When the vehicle body connecting assembly 14 is in the first moving position and the locking part 22 is in the locked state, the vehicle body connecting assembly 14 is fixedly connected to the connecting part 21 of the battery swapping lock body 20 under test. When the locking part 22 is in the unlocked state, the vehicle body connecting assembly 14 can move from the first moving position to the second moving position along the height direction of the bracket 11 in a direction away from the lock body adapter assembly 12. Specifically, the vehicle body connection assembly 14 should have a simulated structure that emulates the connection part 21 of the vehicle body for adapting to the connection part 21 of the battery swapping lock body 20. This simulated structure is positioned corresponding to the connection part 21 of the battery swapping lock body 20 under test, so that after the vehicle body connection assembly 14 is lowered, the simulated structure aligns with the connection part 21. The vehicle body connection assembly 14 moves up and down, causing the simulated structure to move closer to or further away from the battery swapping lock body 20 under test, simulating the process of the battery pack moving closer to or further away from the vehicle body battery pack connection position during battery swapping. This simulated structure can be integrated with the main body of the vehicle body connection assembly 14, or it can be separate from the main body of the vehicle body connection assembly 14 and detachably connected, so that when different types of battery swapping lock bodies 20 under test are replaced on the lock body adapter assembly 12, the corresponding simulated structure can be replaced. More specifically, the vehicle body connection assembly 14 can be manually operated to raise and lower, or a lifting mechanism connected to the vehicle body connection assembly 14 can be provided to drive the vehicle body connection assembly 14 to raise and lower. In one specific embodiment, such as... Figure 1 As shown, the test device 10 also includes a second lifting component 16, which is disposed on the bracket 11 and located above the lock body adapter component 12; the second lifting component 16 is connected to the vehicle body connecting component 14 and can drive the vehicle body connecting component 14 to move along the height direction of the bracket 11.

[0055] When testing the battery swapping lock body 20, the testing device 10 provided by the present invention first lowers the unlocking component 13 to a low position and raises the vehicle body connection component 14 to a high position, so that there is sufficient space above and below the lock body adapter component 12. Then, the battery swapping lock body 20 to be tested is installed on the lock body adapter component 12 in a detachable connection manner. If the unlocking component 131 and the simulated structure of the vehicle body connection component 14 adapted to the battery swapping lock body 20 to be tested change, the unlocking component 131 and the simulated structure need to be replaced. When locking, the unlocking / unlocking assembly 13 is raised to the high position, and the unlocking member 131 is adapted to connect with the locking part 22 of the battery swapping lock body 20 under test, forming a connection state; the vehicle body connection assembly 14 is lowered to the first moving position; the unlocking / unlocking assembly 13 performs a locking action, which is transmitted to the locking part 22 through the unlocking member 131, causing the locking part 22 to switch to the locked state. The process of the locking part 22 switching to the locked state causes the connection part 21 of the battery swapping lock body 20 under test to change state so as to be fixedly connected with the vehicle body connection assembly 14 to achieve locking; after locking is completed, the unlocking member 131 is separated from the locking part 22 to form a separation state, and then the unlocking / unlocking assembly 13 is lowered to the low position. During unlocking, the locking / unlocking component 13 rises from a low position to a high position, and the unlocking member 131 is adapted to connect with the locking part 22 of the battery swapping lock body 20 under test, forming a connection state. The locking / unlocking component 13 then performs an unlocking action, which is transmitted to the locking part 22 through the unlocking member 131, causing the locking part 22 to switch to an unlocked state. This process causes the connecting part 21 of the battery swapping lock body 20 under test to change state, thus disengaging from the vehicle body connecting component 14 and achieving unlocking. After unlocking, the unlocking member 131 separates from the locking part 22, forming a separated state, and then the locking / unlocking component 13 descends to a low position. This locking and unlocking process completes one locking / unlocking test cycle. The locking / unlocking test allows for simulation of the locking / unlocking process during the early stages of battery swapping lock body 20 development, ensuring the reliability of the battery swapping lock body 20. Furthermore, the high consistency of the locking / unlocking component 13's multiple operations improves the accuracy of the test results, increases testing efficiency, and accelerates the development and verification cycle of quick-change models and the locking / unlocking system.

[0056] The testing device 10 provided by this invention can be used to perform durability tests on the battery swapping lock body 20, as well as repeated disassembly and assembly durability and iterative tests on the battery swapping lock body 20, and iterative verification of the unlocking process control strategy.

[0057] According to one specific embodiment of the present invention, such as Figure 3 As shown, the locking / unlocking assembly 13 also includes a rotating mechanism 132, which can rotate about an axis extending along the height direction of the bracket 11; the rotating mechanism 132 is connected to the unlocking member 131, and the rotating mechanism 132 switches between the locked state and the unlocked state by rotating, and drives the unlocking member 131 to rotate.

[0058] Specifically, the locking part 22 of the existing battery swapping lock body 20 usually achieves the transition between the locked and unlocked states by rotation. Therefore, the unlocking component 13 is equipped with a rotating mechanism 132 to drive the unlocking component 131 to rotate, thereby driving the locking part 22 of the battery swapping lock body 20 to achieve the transition between the locked and unlocked states.

[0059] Furthermore, in one specific embodiment of the present invention, such as Figure 4 As shown, the rotating mechanism 132 can be in a first rotating position relative to the unlocking member 131 ( Figure 4 (middle position A) and second rotation position ( Figure 4 The rotation mechanism 132 is adjusted to the B position, wherein when the rotation mechanism 132 is in the first rotation position, the rotation axis of the unlocking member 131 coincides with the rotation axis of the locking part 22; when the rotation mechanism 132 is in the second rotation position, the rotation axis of the unlocking member 131 is parallel to the rotation axis of the locking part 22 and is at a preset distance apart.

[0060] In the first rotation position, the locking part 22 of the battery swapping lock body 20 can be simulated to lock or unlock under normal working conditions after the unlocking component 131 and the locking part 22 are matched and identified. In the second rotation position, the ability of the unlocking component 131 to identify and engage with the coupling interface of the locking part 22 under extreme working conditions can be simulated, thereby enabling the spatial freedom of the unlocking component 131 (i.e., the unlocking / unlocking gun head) and the stability test of the matching dimensions of the coupling interface with the battery swapping lock body 20. The preset distance can be determined based on the offset between the axis of the lock body and the axis of the unlocking / unlocking gun head caused by the cumulative positional errors of multiple battery swapping lock bodies 20 in the battery pack state and the unlocking / unlocking gun heads in the battery swapping station. Specifically, it can be 2mm.

[0061] In one specific embodiment of the present invention, such as Figure 3 As shown, the rotating mechanism 132 includes a motor 1321 and a reducer 1322. The input shaft of the reducer 1322 is connected to the output shaft of the motor 1321, and the output shaft of the reducer 1322 is connected to the unlocking component 131. Specifically, a customized rotating mechanism 132 is formed by adapting the motor 1321 to the reducer 1322, and the output shaft of the reducer 1322 is the rotation axis of the rotating mechanism 132. The unlocking component 131 can be coaxially arranged with the output shaft of the reducer 1322, that is, the rotation axis of the unlocking component 131 coincides with the rotation axis of the rotating mechanism 132. The motor 1321 can be a servo motor with an output torque accuracy of ±0.5Nm, an output angle accuracy of ±1°, a rated torque of 60Nm, and a maximum torque of 180Nm.

[0062] Furthermore, if the rotating mechanism 132 is adjustable relative to the unlocking member 131 at a first rotating position and a second rotating position, such as... Figure 4As shown, the adjustment method can be achieved by manually removing and installing the connecting bolts of the reducer 1322 and rotating it 90 degrees before installation to switch between the two rotational positions.

[0063] According to one specific embodiment of the present invention, such as Figure 2 As shown, the lock body adapter assembly 12 includes a mounting base 121, a base 122, multiple guide posts 123, multiple adjusting screws 124, multiple tension springs 125, and multiple limiting posts 126. The mounting base 121 has mounting holes for mounting the locking part 22 of the battery swapping lock body 20. The mounting base 121 can be detachably connected to the housing of the locking part 22 by fasteners such as bolts. The base 122 has through holes through which the unlocking component 131 can pass and be adapted to the locking part 22. The multiple guide posts 123, multiple tension springs 125, and multiple limiting posts 126 are evenly arranged circumferentially between the base 122 and the mounting base 121. When the locking part 22 is installed, the multiple guide posts 123, multiple tension springs 125, and multiple limiting posts 126 are located on the outer periphery of the locking part 22. The multiple adjusting screws 124 are matched with the multiple tension springs 125 to adjust the tension of the tension springs 125.

[0064] Specifically, the housing of the locking part 22 should be provided with a structure for mounting fasteners, for example, it can be provided as follows: Figure 2 The two connecting lugs 23 shown have bolt holes. The mounting base 121 is provided with a structure for detachable installation via fasteners (such as bolt holes that match the bolt holes on the connecting lugs 23). The locking part 22 and the mounting base 121 are fitted together and precisely positioned via mounting holes and fasteners. Furthermore, the size of the mounting holes on the mounting base 121 is set to accommodate different types of lock bodies 20 and the outer diameter of the locking part 22 housing. The structure on the locking part 22 housing for mounting fasteners (such as bolt holes that match the bolt holes on the connecting lugs 23) is also provided. Figure 2 By matching the positions of the fasteners on the two connecting ears 23) with the positions of the fasteners on the mounting base 121, different types of battery swapping lock bodies 20 to be tested can be adapted; the specific internal structure of the corresponding locking part 22 is not limited. In this way, when replacing the battery swapping lock body 20 to be tested, only the fasteners (such as bolts) need to be removed and installed.

[0065] Mounting bracket 121 is floatingly fixed by guide post 123, tension spring 125, and limiting post 126. The axial limiting tension of mounting bracket 121 can be precisely set by adjusting adjusting screw 124. This is used to simulate the load-bearing condition of battery swapping lock body 20 under extreme working conditions when a single battery swapping lock body 20 is locked due to a fault at the lower end of the vehicle body. This enables the testing of the battery swapping lock body 20 in a failure scenario. At the same time, a proximity switch (not shown in the figure) can be adapted and set in lock body adapter component 12 to automatically identify the padlock condition and achieve the purpose of protecting the test system.

[0066] According to one specific embodiment of the present invention, such as Figure 5 As shown, the vehicle body connection assembly 14 includes a mounting plate 141 and a simulated vehicle body lock hole plate 142 (i.e., the aforementioned simulated structure). The simulated vehicle body lock hole plate 142 can be detachably mounted on the mounting plate 141 via fasteners 143, and is positioned at a position corresponding to the connection portion 21 of the battery swapping lock body 20 under test, so that the simulated vehicle body lock hole plate 142 mates with the connection portion 21 after the vehicle body connection assembly 14 is lowered. Furthermore, when the vehicle body connection assembly 14 is in the first moving position and the locking portion 22 is in the locked state, the simulated vehicle body lock hole plate 142 is fixedly connected to the connection portion 21 of the battery swapping lock body 20 under test. Figure 5 The image shows the vehicle body connection assembly 14 in its first movable position, but the simulated vehicle body lock hole plate 142 is not fixedly connected to the connection part 21 of the battery swapping lock body 20 under test (the locking part 22 is in the unlocked state). This allows the simulated vehicle body lock hole plate 142 to be detachably mounted on the mounting plate 141, facilitating the replacement of the appropriate simulated vehicle body lock hole plate 142 when changing different types of battery swapping lock bodies 20 under test on the lock body adapter assembly 12. Simultaneously, the simulated vehicle body lock hole plate 142 can be replaced with samples of different thicknesses according to testing requirements to verify the reliability of the battery swapping lock body 20's unlocking strategy under different vehicle body thicknesses.

[0067] Furthermore, in one specific embodiment of the present invention, such as Figure 5 As shown, the mounting plate 141 has two elongated holes 1411, which are located on opposite sides of the simulated vehicle body lock hole plate 142, and each elongated hole 1411 is along a first direction ( Figure 5 Extending in the X direction, the first direction is perpendicular to the height direction of the bracket 11; the fastener 143 passes through the elongated hole 1411 so that the simulated car body lock hole plate 142 can be installed on the mounting plate 141, and the position of the simulated car body lock hole plate 142 relative to the mounting plate 141 in the first direction can be adjusted by adjusting the position of the fastener 143 in the elongated hole 1411.

[0068] Specifically, at least two opposite sides of the simulated vehicle body lock hole plate 142 may be disposed below the mounting plate 141, and the fastener 143 may be a bolt. One or more fasteners 143 may be disposed in each elongated hole 1411, specifically as follows: Figure 5Two fasteners 143 are shown. The dimensions of the two elongated holes 1411 can be 8mm × 16mm. The position of the simulated vehicle body lock hole plate 142 relative to the mounting plate 141 along the first direction can be adjusted to deviate from the center position by ±5mm. By adjusting the position of the simulated vehicle body lock hole plate 142 relative to the mounting plate 141 along the first direction, the test condition of simulating the limit offset of the battery swapping lock body 20 relative to the vehicle body lock hole can be realized, and the success rate test of repeated disassembly and assembly with the battery swapping lock body 20 under the limit deviation of the vehicle body lock hole can be carried out. Furthermore, if the width of the elongated hole 1411 is greater than the outer diameter of the fastener 143, the position of the simulated vehicle body lock hole plate 142 relative to the mounting plate 141 along the second direction can also be adjusted. The second direction is perpendicular to the first direction and perpendicular to the height direction of the bracket 11, but the adjustment range is smaller than that along the first direction.

[0069] In one specific embodiment of the present invention, such as Figure 5 As shown, the simulated vehicle body lock hole plate 142 is located below the mounting plate 141. The mounting plate 141 also has a through hole 1412, which is matched with the simulated vehicle body lock hole plate 142 and the connecting part 21. In this way, the movement trajectory of the connecting part 21 of the battery swapping lock body 20 can be observed in real time from above during the test through the through hole 1412.

[0070] In one specific embodiment of the present invention, such as Figure 5 As shown, the mounting plate 141 has scale lines 1413 on at least one side along the first direction and at least one side along the second direction. The second direction is perpendicular to the first direction and perpendicular to the height direction of the bracket 11. The simulated car body lock hole plate 142 also has a first adjusting rod 1421 and a second adjusting rod 1422. The first adjusting rod 1421 extends along the first direction and the end of the first adjusting rod 1421 points to the scale line 1413 in the first direction. The second adjusting rod 1422 extends along the second direction and the ends of the second adjusting rod 1422 also point to the scale line 1413 in the second direction. Specifically, the installation position of the simulated vehicle body lock hole plate 142 in the first direction can be adjusted according to the alignment position of the end of the second adjusting rod 1422 with the scale line 1413. For example, the center position of the simulated vehicle body lock hole plate 142 in the first direction can be determined by aligning the end of the second adjusting rod 1422 with the center of the scale line 1413. The position of the simulated vehicle body lock hole plate 142 in the second direction can also be determined by adjusting the position of the simulated vehicle body lock hole plate 142 in the second direction. The rotation degree of the simulated vehicle body lock hole plate 142 relative to the mounting plate 141 can also be adjusted within a certain range by adjusting the position of the simulated vehicle body lock hole plate 142 in the second direction.

[0071] According to one specific embodiment of the present invention, the testing device 10 further includes a controller, which is connected to the first lifting assembly 15, the unlocking assembly 13 and the second lifting assembly 16 respectively, and is used to control the operation of the first lifting assembly 15, the unlocking assembly 13 and the second lifting assembly 16.

[0072] Specifically, the controller can be installed in a computer or an electrical control cabinet. Figure 6 The electrical control cabinet 17 is shown, in which a controller can be installed. The controller can be used to design corresponding automatic test procedures and parameters based on the type of battery lock body 20, battery pack thickness, etc., and then control the operation of the first lifting assembly 15, the unlocking assembly 13, and the second lifting assembly 16 according to the design. Control modes can include jogging of a single motion axis, manual testing, and automatic testing. The recognition logic of the unlocking component 131, the unlocking process strategy, and the conditions for successful unlocking can be flexibly configured. The controller improves the automation of the testing device 10 and makes the testing process convenient.

[0073] The controller can be connected to the first lifting component 15, the unlocking component 13, etc. via quick-connect electrical connectors. The entire bracket 11 can also be placed inside an environmental chamber, while the controller is placed outside the chamber for continuous high and low temperature alternating tests to verify the disassembly and assembly performance of the battery swapping lock body 20 and the unlocking component 13 in high and low temperature environments.

[0074] Furthermore, in one specific embodiment of the present invention, the testing device 10 further includes a data acquisition module, which is connected to the encryption / unlocking component 13 and the controller respectively; the data acquisition module is used to acquire relevant parameters of the encryption / unlocking component 13 and transmit them to the controller.

[0075] The data acquisition module can specifically be a sensor. If the unlocking / unlocking component 13 includes a rotating mechanism 132, it can acquire the rotation angle and number of rotations of the rotating mechanism 132. Furthermore, if the rotating mechanism 132 includes a motor 1321 and a reducer 1322, the acquisition module can acquire the torque and angle of the output shaft of the motor 1321 and / or the reducer 1322 and transmit them to the controller. This allows the controller to track the changing trends of torque and angle during the unlocking / unlocking process, facilitating the optimization of the unlocking / unlocking strategy and understanding the resistance changes and wear within the unlocking body. Simultaneously, the acquisition module can automatically acquire and save torque and angle data at 20ms intervals. After the test is completed, the controller centrally exports the acquired data for analysis. After a certain number of disassemblies and reassemblies, the torque of the internal threads of the battery swapping lock body 20 will increase. Through extensive data comparison, an average maintenance torque value can be obtained, providing a basis for the subsequent pre-scheduling of inspections and maintenance of the battery swapping lock body 20 by the battery swapping operation department.

[0076] In one specific embodiment of the present invention, such as Figure 6As shown, the testing device 10 also includes a screen 171, which is connected to the controller; the controller and screen 171 can be integrated into an electrical control cabinet 17 to form a control interaction system. The process and parameters of the test method for the battery-swapping lock body 20 under test can be flexibly configured by inputting information through the screen 171; and specific test content and test methods can be selected through the screen 171. Additionally, as... Figure 6 As shown, buttons and other controls can also be installed on the electrical control cabinet 17 for manual operation.

[0077] Data collected by the acquisition module, such as torque and rotation angle, can be displayed on screen 171 for the operator to view in a timely manner. It can also display the changing trends of torque and rotation angle during the unlocking / unlocking process. Figure 7 This shows how the trend of angle change is displayed.

[0078] According to one specific embodiment of the present invention, when the testing device 10 further includes a first lifting assembly 15 and a second lifting assembly 16, such as... Figure 3 As shown, the first lifting assembly 15 includes a lifting base 151 and a first servo electric cylinder 154. The lifting base 151 has a first guide portion 152, and the bracket 11 has a first guided portion 153. The first guide portion 152 and the first guided portion 153 are slidably connected in the height direction of the bracket 11. An unlocking assembly 13 is mounted on the lifting base 151. Specifically, when the unlocking assembly 13 includes a motor 1321 and a reducer 1322, the reducer 1322 is mounted on the lifting base 151. The lifting base 151 may have mounting holes, and the main bodies of the motor 1321 and the reducer 1322 are below the lifting base 151. The output shaft of the reducer 1322 passes through the mounting holes and is above the lifting base 151. The first servo electric cylinder 154 is mounted on the bracket 11 and is used to drive the lifting base 151 to move up and down under the guidance of the first guide portion 152 and the first guided portion 153, thereby moving the unlocking assembly 13 along the height direction of the bracket 11. The first lifting assembly 15 may also include a support base 155 for mounting to the bottom of the bracket 11. The unlocking assembly 13 achieves stepless height adjustment through the first servo cylinder 154 and the guide mechanism, simulating the coupling conditions between the unlocking gun head and the locking part 22 of the battery swapping lock body 20 at different heights.

[0079] like Figure 8 As shown, the second lifting assembly 16 includes a second servo cylinder 161, which is mounted on the top of the bracket 11. The output end of the second servo cylinder 161 faces downward and is connected to the vehicle body connecting assembly 14, and is used to drive the vehicle body connecting assembly 14 to move along the height direction of the bracket 11; wherein, as Figure 5 and 8As shown, the vehicle body connecting assembly 14 is provided with a second guide portion 162, and the bracket 11 is provided with a second guided portion 163. The second guide portion 162 and the second guided portion 163 are slidably connected in the height direction of the bracket 11.

[0080] Specifically, such as Figure 3 , Figure 5 and Figure 8 As shown, the first guide portion 152 and the second guide portion 162 can be holes respectively provided on the lifting seat 151 and the vehicle body connecting assembly 14, and the first guided portion 153 and the second guided portion 163 can be guide rods extending along the height direction of the bracket 11 and connected at one end to the first guide portion 152 and the second guide portion 162 respectively.
