[0046] Optionally, please refer to Figure 6 , Figure 6 is a side view of another battery test tool clamp provided in the embodiment of the present application. The driving component 200 in the battery test tool clamp can include a driving lead screw 201a, the transmission connection hole 102 in the support frame 100 is a threaded connection hole for transmission connection with the driving lead screw 201a, and one end of the driving lead screw 201a can be rotationally connected with the clamping plate 300. That is, the driving lead screw 201a is the driving shaft in the driving component 200. In this case, by cooperation of the driving lead screw 201a and the threaded connection hole in the support frame 100, during rotation of the driving lead screw 201a in one direction, the driving lead screw 201a can drive the clamping plate 300 to move towards the direction close to the battery A, so as to realize clamping of the battery A. While during rotation of the driving lead screw 201a in the other direction, the driving lead screw 201a can drive the clamping plate 300 to move away from the battery.

[0047] It should be noted that in other possible implementations, the driving shaft 201 of the driving component 200 can be an elastic shaft, and the elastic shaft can realize movement and fixation in the transmission connection hole through elastic deformation of itself.

[0048] In the embodiment of the present application, as Figure 6As shown, the driving component 200 in the battery test tooling fixture can further include a driving motor 202 and a mounting plate 203, the mounting plate 203 is arranged opposite to the support frame 100 outside the accommodating cavity 101, and the driving motor 202 can be installed on the side of the mounting plate 203 away from the support frame 100. The output shaft of the driving motor 202 can be in transmission connection with the other end of the driving lead screw 201a. In this way, the driving lead screw 201a can be driven to rotate by the driving motor 202, and the lifting height of the clamping plate 300 is adjusted, so that the automation degree of the battery test tooling fixture is further improved, and the efficiency of the battery test process is improved.

[0049] Optionally, as shown in Figure 6 As shown, the side of the clamping plate 300 in the battery test tooling fixture facing the driving lead screw 201a can have a mounting hole 301, and the driving component 200 can further include a sliding bearing (not shown in the figure) fixed in the mounting hole 301, and the inner ring of the sliding bearing can be sleeved with one end of the driving lead screw 201a. In this way, the sliding bearing is adopted to realize the connection between the end of the driving lead screw 201a and the mounting hole 301 in the clamping plate 300, so as to ensure the stable connection between the driving lead screw 201a and the clamping plate 300.

[0050] In the present application, the number of driving lead screws 201a can be multiple, and the multiple driving lead screws 201a can be correspondingly distributed at multiple corners of the clamping plate 300. Here, in the case that the side of the clamping plate 300 facing the driving lead screw 201a has the mounting hole 301, the number of driving motors 202 and the number of mounting holes 301 can be the same as the number of driving lead screws 201a, and the number of sliding bearings can be the same as the number of mounting holes. For example, the shape of the clamping plate can be square, and the number of driving lead screws 201a can be four, and the four driving lead screws 201a are correspondingly distributed at the four corners of the clamping plate 300.

[0051] In the embodiment of the present application, please refer to Figure 7 , Figure 7is another structural schematic view of a battery test tooling fixture provided by an embodiment of the present application. The battery test tooling fixture can further include a fixed slide rail 400 fixed at an outer side of the support frame 100, a moving guide rail 500 in sliding connection with the fixed slide rail 400, and a moving locking member 600. The moving guide rail 500 can have two slidable sliding blocks 501, each of which can have a limiting hole 501a in communication with the accommodating cavity 101. The moving locking member 600 can be configured to be in fastening connection with the moving guide rail 500 and the fixed slide rail 400 after the moving guide rail 500 moves to a target position. The limiting hole 501a in the sliding block 501 can be used for one end of a functional detection needle to abut against a pole or an explosion-proof valve of the battery A. In this way, the moving guide rail 500 can move along the length direction of the fixed slide rail 400 on the fixed slide rail 400 to adjust the position of the moving guide rail 500. In addition, the sliding block 501 arranged on the moving guide rail 500 can move along the length direction of the moving guide rail 500 to adjust the position of the sliding block 501. In this way, the movement of the sliding block 501 in two directions can be realized, and the position of the sliding block can be adjusted according to the positions of the pole and the explosion-proof valve in the battery, so as to facilitate the butt joint of the functional detection needle and the battery A. Here, after the moving guide rail 500 moves to the target position, the moving locking member 600 can realize the fastening connection of the moving guide rail 500 and the fixed slide rail 400, so as to move the moving guide rail 500 to the optimal position for testing the pole or the explosion-proof valve of the battery. Here, the number of the sliding blocks 501 can be one, and the moving guide rail 500 can have a strip-shaped through slot 502. In this way, one end of the two functional detection needles abuts against the pole of the battery A, and the other end can extend out of the strip-shaped through slot.

[0052] For example, the moving locking member 600 can be a locking screw, and the detachable and fixed connection of the fixed slide rail and the moving guide rail can be realized by the threaded connection of the locking screw with the fixed slide rail 400 and the moving guide rail 500.

[0053] It should be noted that the battery A can have two poles and one explosion-proof valve. Correspondingly, when the functional detection needle abuts against the pole to test the performance of the battery, two functional detection needles are needed to abut against the positive pole and the negative pole of the battery A, respectively. For example, please refer to Figure 8 , Figure 8is a battery pole testing schematic diagram provided by an embodiment of the application using a battery testing fixture clamp. The functional detection probe can be a test probe that abuts the pole of the battery A. The number of test probes T1 can be two. Each test probe T1 can include a test probe body T11 and a spiral spring T12. One end of the test probe body T11 can have a needle tip T111 and a first annular support T112. The needle tip T111 of the test probe body T11 can abut the pole of the battery A. The other end of the test probe body T11 can pass through the limiting hole 501a of the sliding block 501. The spiral spring T12 can be sleeved on the test probe body T11. One side of the spiral spring T12 can abut the first annular support T112, and the other side of the spiral spring T12 can abut the side of the sliding block 501 facing the battery A. In this way, when the battery is tested by abutting the pole with the test probe T1, the needle tip T111 of the test probe body T11 abuts the pole of the battery A, the other end of the test probe body T11 protrudes from the limiting hole 501a in the sliding block 501, and the two sides of the spiral spring T12 abut the first annular support T112 in the test probe body T11 and the sliding block 501 respectively, so as to exert a certain force on the test probe body T11, thereby ensuring the abutting reliability of the needle tip T111 in the test probe body T11 and the pole of the battery. At the same time, the limiting hole 501a in the sliding block 501 can ensure that the test probe body T11 does not deviate during testing.

[0054] Alternatively, please refer to Figure 9 , Figure 9 is a battery anti-explosion valve puncture test schematic diagram provided by an embodiment of the application using a battery testing fixture clamp. The functional detection probe T is a battery puncture needle T2 that abuts the anti-explosion valve of the battery A. The needle tip of the battery puncture needle T2 can pass through the limiting hole 501a in the sliding block 501 to abut the anti-explosion valve of the battery. By applying pressure to the other end of the battery puncture needle T2, the battery puncture needle can perform puncture test on the anti-explosion valve of the battery.

[0055] Optionally, as Figure 7As shown, the support frame 100 in the battery test tooling fixture can include an upper plate 103, a lower plate 104, and a plurality of connecting columns 105. The upper plate 103 and the lower plate 104 can be oppositely arranged, and two ends of each connecting column 105 can be fastened to the upper plate 103 and the lower plate 104 respectively to enclose a receiving cavity 101. A transmission connection hole 102 can be arranged in the upper plate 103. Two ends of the fixed slide rail 400 can be fastened to the upper plate 103 and the lower plate 104 respectively. Among them, the battery A can be placed between the clamping plate 300 and the lower plate 104. Here, after placing the battery between the clamping plate 300 and the lower plate 104, the pole of the battery A and the explosion-proof valve can face the fixed slide rail 400 and the moving slide rail 500. For example, the number of fixed slide rails 400 can be two, and two ends of the moving slide rail 500 can be connected to the two fixed slide rails 400 respectively.

[0056] In this application, as Figure 7 and Figure 4 shown, the upper plate 103 can have a first through hole 103a in communication with the through hole a2 in the clamping plate 300, which can be used to pass the data line of the pressure sensor Q. In this way, by arranging the first through hole 103a in communication with the through hole a2 in the clamping plate 300 in the upper plate 103, the two through holes can be used for the data line of the pressure sensor Q to pass through, making the placement of the data line more convenient and neat.

The support frame with a containing cavity is arranged in the battery test tool clamp, the clamping plate is placed in the containing cavity and connected with one end of a driving shaft of the driving component, and a limiting groove and a through hole coaxially arranged and in communication with each other are arranged on a second side of the clamping plate. In this way, in the battery charge and discharge pressure test, the limiting groove in the clamping plate can be installed with a pressure sensor to be attached to one side close to the side surface of the battery, the driving shaft of the driving component drives the clamping plate to move towards the direction close to the battery, and after the battery is pressed, the pressure sensor is in contact with the surface of the battery. In the charge and discharge process, the battery will expand, and the pressure sensor can obtain the expansion force test data when the battery is tested by cyclic charge and discharge, so as to complete the battery charge and discharge pressure test, and the data line bundle is inserted out of the through hole in the clamping plate to facilitate connection to the expansion force test server.
