A strip frame 15 is provided on the side of the adjusting plate 11 away from the strip plate 10, and the side of the strip frame 15 near the adjusting plate 11 is an open structure. A positioning seat 16 is fixedly installed at the bottom of the strip frame 15, and the bottom of the positioning seat 16 is connected to the support base 1. The top of the support 1 is fixedly connected, and a positioning strip 17 is fixedly installed inside the strip frame 15. A rotating shaft 18 is movably installed through the top of the positioning strip 17, and one end of the rotating shaft 18 extends to the outside of the strip frame 15 and is fixedly connected to the middle of one side of the adjusting plate 11. The other end of the rotating shaft 18 is rotatably connected to the inner wall of the strip frame 15. A synchronous gear 19 is fixedly installed on the side of the positioning strip 17 away from the adjusting plate 11 and outside the rotating shaft 18. An adjusting motor 20 is fixedly installed at the bottom of the side of the strip frame 15 away from the adjusting plate 11, and the adjusting motor 20 is energized and connected to the control switch 6.

[0022] A threaded rod 22 is fixedly installed at the top of the movable frame 8. Positioning vertical rods 23 are provided on both sides of the threaded rod 22, and the two positioning vertical rods 23 are symmetrically fixedly installed at the top of the movable frame 8.

During use, the interaction of the positioning sleeves 26, positioning vertical rods 23, and circular limit blocks 28 allows the movable frame 8 to achieve better stability during movement, thereby ensuring that the adjusting impact assembly 7 can work stably.

[0023] Working principle: During operation, the mounting strip 2 is first fixed to the top of the test workbench using mounting bolts that match the diameter of the mounting hole 3. Then, the adjusting motor 20 is started, driving the sector gear 21 to rotate. During the first half-turn, the sector gear 21 meshes with the synchronous gear 19, driving the synchronous gear 19 to rotate. The synchronous gear 19 drives the rotating shaft 18 to rotate, which in turn drives the adjusting plate 11 to rotate. The adjusting plate 11 drives the connecting shaft 12 to move upward in an arc, which in turn drives the movable strip 13 to move. The movable shaft 14 drives the strip plate 10 to move upward, the strip plate 10 drives the movable frame 8 to move upward, and the movable frame 8 drives the positioning sleeve 26 to slide upward on the outside of the positioning slide rod 27, which can ensure that the movable frame 8 achieves better stability when moving. At the same time, the movable frame 8 drives the impact head 9 to move upward. After the bottom of the impact head 9 moves to the top of the through hole 5, the adjustment motor 20 is stopped, and then the locking nut 25 is unscrewed. The number of strip weights 24 is increased or decreased according to the test needs. Then the locking nut 25 is tightened again so that the strip weights 24 are positioned at the top of the movable frame 8.

[0024] The battery pack to be tested is then placed inside the placement slot 4. The adjusting motor 20 is then restarted, causing the impact head 9 to continue moving upwards. After the synchronous gear 19 rotates 180 degrees, the impact head 9 reaches its highest point. As the sector gear 21 continues to rotate, the synchronous gear 19 disengages from the sector gear 21. At this point, the movable frame 8 loses its driving force and moves downwards under gravity. The movable frame 8 drives the impact head 9 downwards, impacting the battery pack inside the placement slot 4 during its downward movement. As the adjusting motor 20 continues to rotate, the impact head 9 repeats the impact operation on the battery pack several times. Under the specified weight and number of impacts, if the battery pack is not damaged, the test is passed; if the battery pack is damaged, the test is failed. This allows the battery pack safety performance testing device to operate quickly during use, improving testing efficiency and facilitating better practicality.
