[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0022] Example 1:

[0023] See Figure 1 and Figure 2 As shown, this embodiment provides a battery testing fixture, which includes: a test chamber 100, wherein the test chamber 100 has a test channel 130 extending along a first direction X, and the battery to be tested enters the test chamber 100 along the test channel 130; a guide docking mechanism 300, wherein the guide docking mechanism 300 includes a lifting frame 320, a guide pressing component 340, and a docking component 350, wherein the guide pressing component 340 and the docking component 350 are respectively connected to the lifting frame 320 and move synchronously up and down through the lifting frame 320; the guide pressing component 340 includes a guide wheel 343, and the docking component 350 includes a connector 351; both the guide wheel 343 and the connector 351 can be moved into the test chamber 100, wherein the guide wheel 343 rolls against the top surface of the battery to be tested, and the connector 351 is located at the extended end of the test channel 130 to be inserted into the charging and discharging interface of the battery to be tested.

[0024] It should be noted that, for ease of description, in this embodiment, the depth direction in the horizontal plane of the test chamber 100 is defined as the first direction X, the arrangement direction of the multiple test chambers 100 is defined as the second direction Y, and the height direction of this tooling is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other, and the first direction X and the second direction Y are located in the same plane.

[0025] In this embodiment, the battery testing fixture includes multiple test chambers 100, thereby forming a parallel operation structure of multiple independent test units, which greatly improves the efficiency of batch testing and adapts to the large-scale testing needs of battery production lines. Each test chamber 100 can independently form a closed and stable testing environment, avoiding interference between different test units. At the same time, combined with the multiple specification test channels 130 that can be set in each test chamber 100, it can further accommodate the testing needs of different battery models. This not only reduces the time spent on frequently changing the compatibility specifications of a single test chamber 100, but also reduces the overall space occupied by the equipment through the synchronous operation of multiple units. Furthermore, if an abnormality occurs in one test chamber 100, it will not affect the normal operation of other test chambers 100, ensuring the continuity and stability of the testing process.

[0026] Specifically, see Figure 3 and Figure 4As shown, in this embodiment, each test chamber 100 is provided with at least two test channels 130 arranged along its height direction. A partition strip 150 is provided between adjacent test channels 130 to transport at least two types of batteries to be tested. This design effectively avoids collisions or positional interference between batteries in different channels during transmission. Simultaneously, based on the height difference of the channels and the isolation effect of the partition strip 150, this structure can specifically transport at least two types of batteries to be tested. Larger batteries are placed in the unobstructed upper test channel 130, utilizing the openness of the upper space and avoiding transmission bottlenecks caused by limited channel space for large batteries. Smaller batteries are placed in the lower test channel 130. The compact layout of the lower channel provides more stable positioning for smaller batteries, ensuring that batteries of different models can move smoothly within their respective suitable channels, further improving the compatibility and transmission stability of the testing fixture for multiple battery specifications.

[0027] Furthermore, the partition bar 150 is provided with a clearance groove 151, through which the guide wheel 343 can move between at least two test channels 130. The size of the clearance groove 151 is adapted to the outer diameter and thickness of the guide wheel 343. When the guide docking mechanism 300 needs to guide and press the batteries in different test channels 130, the guide wheel 343 does not need to significantly adjust its overall position with the lifting frame 320. It can move flexibly between at least two test channels 130 simply by following the trajectory of the clearance groove 151. This further enhances the compatibility of the test fixture with batteries of multiple specifications, while shortening the test switching time between different channels and improving the overall test efficiency.

[0028] In this embodiment, the test chamber 100 includes a base plate 110, two side plates 120, and at least one fixing component 140. The two side plates 120 are respectively disposed on both sides of the base plate 110 in the second direction Y. The fixing component 140 includes a locking plate 141, a connecting pin 142, and a push block 143. The locking plate 141 is connected to the outer wall of at least one of the side plates 120. One end of the connecting pin 142 is connected to the locking plate 141, and the other end passes through the locking plate 141 and connects to the push block 143. At least a portion of the push block 143 is located within the test channel 130 and abuts against the battery to be tested along the second direction Y. The base plate 110 serves as a load-bearing foundation, providing a horizontal support surface for the battery. The two side plates 120 are respectively erected on both sides of the base plate 110 along the second direction Y, jointly defining the lateral boundary of the test channel 130 and limiting the significant displacement of the battery along the second direction Y during transmission. The fixing component 140 further enhances the battery's positioning accuracy. It is fixed to the outer wall of at least one side plate 120 via a locking plate 141, forming a stable installation reference. Specifically, when the battery enters the test channel 130, the push block 143 forms a stable abutment against the side of the battery along the second direction Y. This not only allows for adjustment of the abutment force according to the width of different battery models via the connecting pin 142, ensuring that the battery is centered or in a preset position within the channel, but also prevents attitude deviation caused by shaking during battery transport. This lays a reliable positional foundation for the subsequent pressing and guiding of the guide wheel 343 and the precise insertion of the connector 351.

[0029] See Figure 5As shown, the battery testing fixture also includes a stop positioning mechanism 200, which is disposed at the end of the test channel 130, thereby forming an interception cooperation with the battery transmission direction. Specifically, the stop positioning mechanism 200 includes a stop plate 210, a buffer stop piece 220, and a trigger switch 230. The buffer stop piece 220 is disposed on the side of the stop plate 210 facing the test channel 130 to abut the battery being tested. The trigger switch 230 is connected to the stop plate 210 and is disposed facing the test channel 130. Among them, the stop plate 210 serves as a basic support component, fixed perpendicular to the extension direction of the test channel 130, forming a physical limit reference for the battery position; the buffer stop plate 220 is made of elastic material. When the battery to be tested is transported to the end of the channel, it will first contact the buffer stop plate 220, absorbing the inertial impact force of the battery through its own deformation, avoiding rigid collision between the battery and the stop plate 210, which would cause appearance damage or positional displacement; the trigger switch 230 is also connected to the stop plate 210, with its sensing end facing the inside of the test channel 130. When the battery presses against the buffer stop plate 220 and pushes it to deform slightly, the switch 230 will be triggered simultaneously. The switch will then send a battery positioning signal to the control mechanism of the tooling, providing a precise timing trigger for subsequent actions such as starting the pressing of the guide docking mechanism 300 and inserting the connector 351, ensuring that each test is conducted under the premise of accurate battery positioning.

[0030] See Figure 6As shown, the guide docking mechanism 300 in this embodiment integrates the lifting frame 320, the guide pressing component 340, and the docking component 350 to form an integrated linkage structure for guiding, positioning, and docking. The lifting frame 320 synchronously drives the guide pressing component 340 and the docking component 350 to rise and fall, thereby achieving overall displacement adjustment. When it rises, it can allow both to exit the test channel 130, and when it falls, it can accurately send the guide wheel 343 and the docking connector 351 into the working position inside the test chamber 100. Specifically, the guide docking mechanism 300 includes a mounting frame 310 and a lifting driver 330. The mounting frame 310 is supported on one side of the test chamber 100 and has a lifting module 311 extending in the third direction Z. The lifting driver 330 is located on one side of the mounting frame 310, and its working end is connected to the lifting frame 320 to drive the lifting frame 320 to slide and connect to the lifting module 311. The mounting frame 310, serving as the core support structure, is securely mounted on one side of the test chamber 100, providing a reliable installation benchmark and spatial positioning for the entire guiding docking mechanism 300. The mounting frame 310 is equipped with a lifting module 311 extending Z-direction, providing a precise guide trajectory for the movement of the lifting frame 320. When the lifting drive 330 is activated, it drives the lifting frame 320 to smoothly slide up and down along the lifting module 311, thereby precisely controlling the height position of the guiding pressing assembly 340 and the docking assembly 350.

[0031] Furthermore, the guide wheel 343, by abutting against the top surface of the battery under test and rolling with the battery, creates a dynamic constraint on the battery. It applies appropriate pressure to ensure the bottom surface of the battery adheres to the test channel 130, while the rolling contact reduces frictional resistance, preventing obstruction of battery movement. The entire assembly, through continuous abutment guidance, corrects any minor tilting or offset that may occur in real time, ensuring the battery remains horizontal throughout its entry into the test channel 130, laying the foundation for precise insertion of the end connector 351.

[0032] Furthermore, the guide pressing assembly 340 includes an assembly plate 342, a floating connecting column 341, and at least two guide wheels 343. One end of the floating connecting column 341 is connected to the lifting frame 320, and the other end is connected to the assembly plate 342. The assembly plate 342 extends horizontally, and at least two guide wheels 343 are respectively connected to the assembly plate 342. The assembly plate 342, extending horizontally, serves as the mounting carrier for the guide wheels 343, providing a stable mounting reference for the at least two guide wheels 343. The arrangement of the guide wheels 343 adapts to the force requirements of the battery's top surface, ensuring a balanced downward pressure on the battery. The floating connecting column 341 connects the lifting frame 320 and the assembly plate 342, and has a certain elastic extension or swing margin, allowing for adaptive adjustment based on minor undulations or positional deviations of the battery's top surface, ensuring that the guide wheels 343 always fit tightly against the battery's top surface without excessive pressure. As the battery moves along the test channel 130, the guide wheel 343 rolls accordingly. This ensures the battery remains horizontal through continuous resistance and reduces resistance to battery transmission by utilizing rolling friction, preventing scratches on the battery surface or transmission jams. This provides a stable posture guarantee for the subsequent precise insertion of the connector 351 into the battery charging and discharging interface.

[0033] In this embodiment, the connector 351 is designed to match the charging / discharging interface of the battery under test. Before the guide pressing assembly 340 ensures the battery is horizontally positioned, the connector 351 is positioned to wait for battery insertion, thereby establishing a stable electrical connection channel. Specifically, the docking assembly 350 also includes an extension plate 352. One end of the extension plate 352 is connected to the lifting frame 320, and the other end extends towards the extended end of the test channel 130. The connector 351 is mounted on the extension plate 352 and faces the test channel 130. The extension plate 352 serves as the mounting and extension carrier for the connector 351. One end of the extension plate 352 is fixedly connected to the lifting frame 320 to ensure synchronous lifting and lowering with the lifting frame 320, while the other end extends horizontally towards the extended end of the test channel 130, allowing the connector 351 to accurately reach the corresponding position of the battery charging / discharging interface. The connector 351 is installed on the side of the extension plate 352 facing the test channel 130, and its orientation is consistent with the battery transmission direction. When the lifting frame 320 drives the docking assembly 350 to descend to the working position, the length design of the extension plate 352 can ensure that the connector 351 and the battery charging and discharging interface at the end of the test channel 130 are on the same axis. With the stable control of the battery posture by the guide pressing assembly 340, the connector 351 and the battery interface can be accurately aligned and plugged in, establishing a reliable circuit connection for charging and discharging tests.

[0034] The guiding docking mechanism 300 in this embodiment further includes an external component 360. The external component 360 includes an adjustment module 361, an external plate 362, a connecting plate 363, and an adjustment driver 364. The adjustment module 361 is mounted on the lifting frame 320 and extends along the first direction X. One side of the external plate 362 is slidably connected to the adjustment module 361, and the other side is connected to an external communication testing device. The adjustment driver 364 is mounted on the external plate 362. Both ends of the connecting plate 363 are respectively connected to the working end of the adjustment driver 364 and the lifting frame 320. The external component 360 provides an adjustable connection carrier for adapting the tooling to external communication testing equipment, while ensuring precise coordination between the equipment and the battery testing link. In its structure, the adjustment module 361 is fixed on the lifting frame 320 and extends along the first direction X, providing a directional trajectory for the movement of the external plate 362. One side of the external plate 362 is slidably engaged with the adjustment module 361, and the other side serves as a mounting surface for fixing external communication test equipment, thereby realizing the physical connection between the test equipment and the tooling. The adjustment driver 364 is mounted on the external plate 362, and its working end is connected to the lifting frame 320 through the connecting plate 363. When the adjustment driver 364 is activated, it can drive the external plate 362 to slide flexibly along the adjustment module 361 in the first direction X, thereby accurately adjusting the relative position of the external test equipment, the connector 351, and the battery, ensuring that the test equipment can accurately acquire data signals during the battery charging and discharging process.

[0035] Furthermore, the battery testing fixture in this embodiment also includes a fixed mounting plate 400 and a control mechanism. The test chamber 100, the stop positioning mechanism 200, and the guide docking mechanism 300 are all mounted on the fixed mounting plate 400, and the stop positioning mechanism 200 and the guide docking mechanism 300 are respectively connected to the control mechanism. In actual production and processing, operators can adjust the above structure in real time through the control mechanism, thereby improving the flexibility of the equipment. Parameters can also be preset through the control mechanism, thereby improving the automation level of the equipment.

[0036] Example 2:

[0037] This embodiment provides a battery testing system, which includes the battery testing fixture described in Embodiment 1.

[0038] In summary, the battery testing fixture and system described in this invention, through the test chamber 100, constructs an independent and adaptable test space for the battery under test, effectively isolating it from external environmental interference and laying a stable foundation for subsequent accurate testing. Simultaneously, with the help of the guide pressing component 340 in the guide docking mechanism 300, a precise contact and guiding structure is built for the battery under test to limit and dynamically correct its movement trajectory, ensuring that the battery maintains a horizontal posture throughout the entire process of entering the test chamber 100, fundamentally avoiding the problem of misalignment of the charging and discharging interfaces caused by battery tilting. Based on the above design, the charging and discharging interfaces of the battery under test can achieve high-precision insertion with the docking component 350, significantly reducing the risk of test interruption caused by interface docking deviation, while also greatly reducing data errors and ensuring the reliability of test data.

[0039] Compared to existing charge-discharge testing structures, this application, through the adaptive adjustment capability of the guide pressing component 340, can flexibly adapt to the testing needs of batteries of different sizes and models, eliminating the need for frequent tooling changes, reducing operating costs and time losses. At the same time, the precise guiding and docking structure eliminates the debugging process, effectively increasing the number of test batches per unit time and adapting to large-scale testing scenarios. In addition, this application also features strong controllability, flexible use, and wide applicability, and can stably output accurate test results, providing an efficient and reliable solution for battery performance testing.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
