[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0023] like Figures 1 to 4 As shown, an embodiment of the present invention provides an energy storage battery testing device 100, which includes a base frame 10 and a detection assembly 20. The base frame 10 includes a guide rod 11, a bottom plate 13 and a top plate 12 arranged opposite to each other. The two ends of the guide rod 11 are correspondingly connected to the bottom plate 13 and the top plate 12. The bottom plate 13 is provided with a clamping assembly 14, and the clamping assembly 14 is used to clamp the energy storage battery 200. The detection assembly 20 includes a transmission screw 21, a test plate 22 and a probe 23 provided on the test plate 22. The test plate 22 is slidably provided on the guide rod 11. One end of the transmission screw 21 passes through the top plate 12 and is connected to the test plate 22. The transmission screw 21 is rotatable relative to the top plate 12 to drive the test plate 22 and the probe 23 to move. A locking member 24 is provided between the transmission screw 21 and the top plate 12, thereby achieving fixation between the transmission screw 21 and the top plate 12.

[0024] In this embodiment, two guide rods 11 are provided. These two guide rods 11, the base plate 13, and the top plate 12 form a stable test platform, providing a stable support structure for the entire test apparatus. The guide rods 11, acting as a bridge connecting the base plate 13 and the top plate 12, not only ensure the stability of the entire structure but also provide precise guidance for the movement of the detection assembly 20. The clamping assembly 14 secures the energy storage battery 200 to the base plate 13, preventing shaking or displacement during testing and ensuring the accuracy of the test results.

[0025] The guide rod 11 extends vertically, and the test plate 22 slides on the guide rod 11, enabling vertical movement. One end of the drive screw 21 passes through the top plate 12 and connects to the test plate 22. Rotating the drive screw 21 precisely controls the movement of the test plate 22 and its probe 23 toward or away from the bottom plate 13, thereby bringing the probe 23 into contact with or out of contact with the pole 210 of the energy storage battery 200. This not only achieves high movement accuracy but also covers a greater travel distance, meeting the testing requirements of different types of energy storage batteries 200.

[0026] Furthermore, a locking member 24 is positioned between the drive screw 21 and the top plate 12. This not only effectively prevents loosening of the threads due to temperature fluctuations during testing, but also ensures stable contact between the probe 23 and the terminal 210 of the energy storage battery 200, significantly improving the reliability and safety of the testing process. More importantly, when the energy storage battery 200 needs to be replaced, the operator can quickly adjust the locking member 24 to release the fixed state of the drive screw 21, thereby enabling rapid movement of the test plate 22. This greatly simplifies the process of replacing the energy storage battery 200 and improves testing efficiency.

[0027] In summary, the energy storage battery testing device 100 provided in the embodiment of the present invention can realize efficient and accurate testing of the energy storage battery 200 while taking into account the convenience and safety of operation, providing strong technical support for the research and development and production of the energy storage battery 200.

[0028] like Figure 2 As shown, in some embodiments, the locking member 24 includes a sleeve 241, in which a thread is provided that is opposite to the rotation direction of the transmission screw 21. The sleeve 241 is sleeved on the transmission screw 21, and the sleeve 241 is located on the side of the top plate 12 facing away from the test plate 22, thereby achieving effective locking of the transmission screw 21.

[0029] Specifically, the sleeve 241, through the interaction of threads, can achieve a tight fit and effective locking with the transmission screw 21. Furthermore, the sleeve 241 is located on the side of the top plate 12 facing away from the test plate 22. This not only ensures that the locking member 24 does not interfere with the movement of the test plate 22 and the probe 23 thereon during operation, but also allows the operator to easily access and operate the locking member 24 from the top, thereby achieving rapid locking and unlocking of the transmission screw 21.

[0030] To secure the position of the drive screw 21, simply rotate the sleeve 241. Since the internal threads of the sleeve 241 rotate in the opposite direction of the drive screw 21, the rotation of the sleeve 241 causes it to move downward along the drive screw 21 and gradually abut against the top plate 12, ultimately achieving a secure locking effect. This locking method is not only stable and reliable, but also effectively prevents loosening of the threads due to factors such as temperature changes or vibration during testing, thereby ensuring stable contact between the probe 23 and the pole 210 of the energy storage battery 200.

[0031] When it is necessary to replace the energy storage battery 200 or adjust the position of the test plate 22, the locking state can be easily released by simply rotating the sleeve 241 in the opposite direction, allowing the transmission screw 21 to resume free rotation. In this way, the test plate 22 can be moved quickly and accurately under the drive screw 21, greatly simplifying the operation process of replacing the energy storage battery 200 or adjusting the test position.

[0032] Furthermore, the locking member 24 includes two ears 242, which are disposed on opposite sides of the sleeve 241, thereby facilitating the rotation of the sleeve 241. In other words, when the drive screw 21 is locked or unlocked, the sleeve 241 can be rotated via the ears 242, causing the sleeve 241 to abut or separate from the top plate 12, thereby achieving locking or unlocking. In this embodiment, the locking member 24 can be configured as a nut.

[0033] like Figure 1 and Figure 2 As shown, in some embodiments, the transmission screw 21 is provided with a through hole 211, and a boost lever 25 is passed through the through hole 211. Specifically, the through hole 211 is provided at one end of the transmission screw 21 away from the test plate 22. When the position of the test plate 22 needs to be adjusted, the operator can easily hold one end of the boost lever 25 and drive the transmission screw 21 to rotate by applying an appropriate amount of force, thereby achieving precise control and locking / unlocking operations of the test plate 22, which not only simplifies the operating process, but also greatly improves the accuracy and efficiency of the operation. Compared with the traditional method of directly rotating the transmission screw 21, the use of the boost lever 25 can more easily overcome the resistance and friction during the rotation process, making the rotation of the transmission screw 21 smoother and more stable.

[0034] Optionally, the boosting lever 25 may be provided with anti-slip grooves, which can effectively increase the friction between the operator's hand and the boosting lever 25, so that when rotating the transmission screw 21, even if the hand is sweating or lubricated, a firm grip can be maintained, avoiding operational errors or safety accidents caused by slipping.

[0035] In some embodiments, the clamping assembly 14 includes a first clamping block 141 and a second clamping block 143 arranged opposite to each other. The first clamping block 141 and the second clamping block 143 are movably arranged on the base plate 13 to align the pole 210 of the energy storage battery 200 with the probe 23, so that it can be flexibly adjusted according to the size and shape of the energy storage battery 200 to ensure that the pole 210 of the energy storage battery 200 is accurately aligned with the test probe 23, which can effectively avoid damage or errors caused by misalignment of the pole 210 and the probe 23 during the test process.

[0036] Furthermore, the first clamping block 141 has a first clamping surface 142, and the second clamping block 143 has a second clamping block 143 opposite the first clamping surface 142. The base plate 13 is provided with a first scale extending from the first clamping surface 142 toward the second clamping surface 144. In other words, the first clamping surface 142 can fit tightly against one side of the energy storage battery 200, and the second clamping surface 144 is used to clamp the other side of the battery. This ensures that the energy storage battery 200 maintains a stable posture during testing, preventing it from shaking or tilting and affecting the test results. Furthermore, the first clamping block 141 and the second clamping block 143 are movable along the first scale, providing an intuitive visual reference, allowing the operator to more accurately judge and adjust the distance between the first clamping block 141 and the second clamping block 143.

[0037] Furthermore, the first clamping block 141 and the second clamping block 143 may be provided with waist-shaped holes, which extend in a direction opposite to the first clamping surface 142 and the second clamping surface 144. The bottom plate 13 may be provided with positioning posts, which are movably inserted into the waist-shaped holes to achieve the movement and fixation of the first clamping block 141 and the second clamping block 143. It should be noted that in other embodiments of the present invention, the waist-shaped holes may also be provided on the bottom plate 13, and the fixing posts may be provided on the first clamping block 141 and the second clamping block 143 accordingly.

[0038] In some embodiments, two probes 23 are provided, movably mounted on the test board 22, and the spacing between the two probes 23 is adjustable. In other words, the two probes 23 are not only independent of each other but also movable, meaning their positions and the spacing between them can be adjusted according to actual testing requirements. This accommodates the differences in spacing between the poles 210 of different energy storage batteries 200, making the test device applicable to a wider range of battery models.

[0039] In some embodiments, the detection assembly 20 also includes a fixing sleeve 26 and an elastic member 27. The fixing sleeve 26 is movably arranged on the test board 22, and the probe 23 is inserted into the fixing sleeve 26. The two ends of the elastic member 27 are correspondingly connected to the fixing sleeve 26 and the probe 23, so that when the probe 23 contacts the pole 210 of the energy storage battery 200, the test current or voltage can be applied more gently through the buffering effect of the elastic member 27, thereby avoiding battery damage or test errors caused by sudden impact.

[0040] Furthermore, the elastic member 27 allows the probe 23 to better adapt to even minor surface irregularities of the battery terminal 210 during testing, improving the accuracy and reliability of the test. When external forces act on the probe 23, the elastic member 27 absorbs and disperses these forces, maintaining stable contact and ensuring accurate and consistent test data.

[0041] In some embodiments, the test board 22 is provided with a slot 221, and the fixing sleeve 26 is provided in the slot 221. The fixing sleeve 26 also includes an upper clamping plate 261 and a lower clamping plate 262. The upper clamping plate 261 and the lower clamping plate 262 are relatively arranged on both sides of the test board 22. The upper clamping plate 261 and / or the lower clamping plate 262 are provided with positioning parts, so that the position of the fixing sleeve 26 in the slot 221 can be positioned, so that the probe 23 can maintain a more stable contact state during the test process, thereby improving the accuracy and reliability of the test.

[0042] Specifically, the fixing sleeve 26 also includes a sleeve 263, one end of which is connected to the upper clamping plate 261, and the other end of the sleeve 241 is connected to the lower clamping plate 262. This allows the fixing sleeve 26 to move along the slot 221 to ensure that the probe 23 contacts the terminal 210 of the energy storage battery 200. Furthermore, the upper clamping plate 261, the lower clamping plate 262, and the positioning member ensure that the fixing sleeve 26 fits more tightly within the slot 221, reducing testing errors caused by shaking or loosening. In this embodiment, the positioning member can be configured as a set screw.

[0043] Furthermore, one end of the sleeve 263 can be welded to the lower clamping plate 262, and the other end of the sleeve 263 can be connected to the upper clamping plate 261 through a thread, which not only ensures the stability of the structure but also greatly improves the flexibility and efficiency of assembly.

[0044] Furthermore, a second scale is provided on the test plate 22 , and the second scale is provided along the moving direction of the fixing sleeve 26 to determine the moving position and moving distance of the probe 23 .
