When the position of the connecting frame 310 needs to be adjusted, the first fastening clamp 320 can be loosened so that it can move along the extension direction of the moving beam 200 to adjust the position of the connecting frame 310. When the connecting frame 310 moves to the desired position, the first fastening clamp 320 can be tightened so that it clamps the moving beam 200 to fix the position of the connecting frame 310. At this time, the connecting frame 310 can be connected to the battery pack 10 through the connecting hole 311. Therefore, the battery pack scratch test rack of this embodiment can adjust the position of the connecting frame 310 so that the connecting hole 311 on the rack corresponds to the hanging hole on different types of batteries, thereby increasing the types of battery packs 10 that the rack can fix, expanding the scope of use, increasing the versatility of the rack, shortening the test cycle of scratch test, and reducing the test cost of scratch test.

The second clamping plate 322 is connected to the connecting frame 310. That is, by using the cooperation of the first nut 324 and the connecting bolt 323, the interval between the first clamping plate 321 and the second clamping plate 322 can be adjusted to adjust the clamping space of the movable beam 200, thereby adjusting the tightness of the first fastening clamp 320 so as to adjust the position of the connecting frame 310.

[0035] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 Both the first clamping plate 321 and the second clamping plate 322 are square, and a plurality of connecting bolts 323 are distributed on the edge of the first clamping plate 321.

[0038] In some embodiments of this utility model, the number of connecting components 300 on a single movable beam 200 is two, that is, the same movable beam 200 can be connected to two empty slots of the battery pack 10 to better mount the battery pack 10.

[0039] In some embodiments of this utility model, reference is made to Figures 1 to 3The connecting device 210 includes a second fastening clamp 211. The second fastening clamp 211 is adjustable in tightness and is used to clamp the fixed beam 100. The second fastening clamp 211 is fixed to the movable beam 200. The adjustable tightness of the second fastening clamp 211 controls whether it clamps the fixed beam 100. When the position of the movable beam 200 needs to be adjusted, the second fastening clamp 211 can be loosened so that it can move along the extension direction of the fixed beam 100 to adjust its position. When the movable beam 200 moves to the desired position, the second fastening clamp 211 can be tightened to clamp the movable beam 200 and fix its position. This, in conjunction with the first fastening clamp 320, adjusts the position of the connecting frame 310 in two directions to better accommodate different types of battery packs 10.

The U-shaped clamp 213 is fitted onto the fixed beam 100, and the external threaded sections 215 at both ends of the U-shaped clamp 213 pass through the second through holes 216 of the third clamping plate 212. By rotating the second nut 214, the distance between the third clamping plate 212 and the fixed beam 100 can be adjusted so that the third clamping plate 212, in conjunction with the U-shaped clamp 213, clamps the fixed beam 100 to fix the position of the moving beam 200. Specifically, one moving beam 200 is connected to two fixed beams 100 via two second fastening clamps 211 to ensure that the moving beam 200 does not wobble; one second fastening clamp 211 is connected to the third clamping plate 212 via two U-shaped clamps 213 to ensure a more reliable connection between the moving beam 200 and the fixed beam 100.

[0041] In some embodiments of this utility model, reference is made to Figure 1 and Figure 6 The fixed beam 100 is provided with a fixing mechanism 110 for connecting to an external device. The fixing mechanism 110 can be connected to the external device using fasteners such as bolts, screws, and pipe clamps. The external device can be the beam frame 20 of a test device for performing scratch tests, so that the bracket can be installed on the beam frame 20 to facilitate the connection between the beam frame 20 of the test device and the battery pack 10.

[0042] In summary, in this embodiment, the connecting frame 310 is connected to the moving beam 200 via a first fastening clamp 320. The first fastening clamp 320 is adjustable in tightness. When the position of the connecting frame 310 needs to be adjusted, the first fastening clamp 320 can be loosened so that it can move along the extension direction of the moving beam 200 to adjust the position of the connecting frame 310. When the connecting frame 310 moves to the desired position, the first fastening clamp 320 can be tightened so that it clamps the moving beam 200 to fix the position of the connecting frame 310. At this time, the connecting frame 310 can be connected to the battery pack 10 through the connecting hole 311. Therefore, the battery pack scratch test rack of this embodiment can adjust the position of the connecting frame 310 so that the connecting hole 311 on the rack corresponds to the hanging hole on different types of batteries, thereby increasing the types of battery packs 10 that the rack can fix, expanding the scope of use, increasing the versatility of the rack, shortening the test cycle of scratch testing, and reducing the test cost of scratch testing.

[0043] The above are merely preferred embodiments of this utility model.
