Description

Technical Field

[0001] This utility model relates to the field of battery protection board technology, and specifically to a battery protection board testing fixture. Background Technology

[0002] Lithium-ion batteries are advantageous due to their high energy density and lack of memory effect. However, they lack built-in protection and may pose safety hazards such as overcharging, over-discharging, and short circuits during use. Therefore, lithium-ion battery packs are equipped with protection boards that provide multiple protections against overcharging, over-discharging, short circuits, and temperature fluctuations.

[0003] Chinese Patent No. CN213302383U discloses a multifunctional testing device for lithium battery protection boards, including a test platform. A side frame is fixedly connected to the rear side of the top of the test platform. Mounting blocks are fixedly connected to both sides of the front of the side frame, and a shaft is fixedly connected to the bottom of the mounting blocks. The bottom of the shaft is fixedly connected to the top of the test platform, and a movable plate is sleeved on the surface of the shaft. A threaded rod is rotatably connected to the middle of the rear side of the movable plate, and a rotating component is fixedly connected to the top of the threaded rod. A threaded sleeve is threadedly connected to the surface of the threaded rod, and the rear side of the threaded sleeve is fixedly connected to the front of the side frame through a connector. This utility model relates to the technical field of battery protection board testing equipment. This multifunctional testing device for lithium battery protection boards solves the problem that existing technologies require changing the lower mold fixture when testing different models of battery protection boards, which is time-consuming, labor-intensive, and inefficient.

[0004] However, in the above technical solution, the positioning groove of the protection plate is only fixedly connected to the guide rods around the inner wall of the protection plate positioning groove. The setting of the sleeve and spring makes the positioning groove of the protection plate suitable for different models of battery protection plates. However, in this structure, the guide rods are connected to the fixed plate, and the position of the protrusions on the fixed plate is restricted. When the size of the battery protection plate changes, the protrusions cannot adjust their own position to adapt to the battery protection plates of different sizes. Utility Model Content

[0027] Example 4

[0028] like Figure 3 As shown, the present invention proposes a battery protection board testing fixture. Compared with Embodiment 3, this embodiment describes the detailed structure of the clamping assembly. The clamping assembly includes a connecting plate 22, a clamping block 23, a threaded rod 24, and an adjusting knob 25. The connecting plate 22 is connected to the fixed base 7, and the connecting plate 22 is set at a 45-degree angle to the fixed base 7.

The rotation of the adjusting rod 11 drives the rotating block 13 to rotate, and the rotation of the rotating block 13 pushes the two side clamping blocks 9 on both sides to move along the receiving cavity. After the clamping blocks 9 lose their restraint, the elastic element 10 rebounds and retracts them into the receiving cavity. At this time, the fixing seat 7 can be adjusted. The clamping block 23 can be adjusted by setting a scale. After adjustment, the clamping block 23 can be further adjusted by pushing the adjustment knob 25 to rotate the threaded rod 24. When the threaded rod 24 rotates, the clamping block 23 moves along the axis of the threaded rod 24 on the connecting plate 22. The clamping block 23 is close to the corner of the battery protection board to restrict and fix it. Then, the operator starts the telescopic device 18. The telescopic end of the telescopic device 18 drives the mounting plate 20 to move vertically. The test probe 21 on the mounting plate 20 contacts the battery protection board to perform the test.
