[0025] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0026] like Figure 1-2 As shown, as a battery drop test detection device of the utility model, it includes a supporting base plate 1, a pressure detector 18 arranged on the supporting base plate 1 and a top plate 3 arranged above the supporting base plate 1, a telescopic rod 2 for adjusting the height of the top plate 3 is provided between the top plate 3 and the supporting base plate 1, a movable plate 4 is slidably provided on the telescopic rod 2, a clamping mechanism for clamping the battery is provided at the bottom of the movable plate 4, and a driving member for driving the movable plate 4 to adjust along the direction of the telescopic rod 2 is provided on the top plate 3.

[0027] Specifically, the height of the top plate 3 can be adjusted by the telescopic rod 2, and the top plate 3 drives the driving member that drives the movable plate 4 to adjust along the direction of the telescopic rod 2. Through the two height adjustment methods, on the one hand, the adjustable height of the clamping mechanism on the movable plate 4 can be larger, and on the other hand, the position of the clamping mechanism can be fine-tuned. The required height when the battery falls can be accurately adjusted, and the accuracy of the experimental detection is higher;

[0028] like Figure 1 As shown, an infrared distance sensor 19 for height detection is installed on the upper surface of the supporting base plate 1.

[0029] The pressure tester 18 installed on the upper surface of the supporting base plate 1 is convenient for the pressure tester 18 to detect the pressure of the battery when it falls, and the infrared distance sensor 19 is used to monitor the height after lifting.

[0030] like Figure 3 As shown, the clamping mechanism includes a positioning plate 10, a telescopic cylinder 11, a clamping plate 12 and a limiting rod 13. The positioning plate 10 is welded to the bottom of the movable plate 4. The telescopic cylinder 11 is fixed to the outer surface of the positioning plate 10. The clamping plate 12 is fixed to the telescopic end of the telescopic cylinder 11. The limiting rod 13 is welded on the surface of the positioning plate 10, and the clamping plate 12 is slidably connected to the limiting rod 13.

[0031] Specifically, the telescopic cylinder 11 works to drive the clamping plate 12 to move, so that the clamping plate 12 clamps and limits the battery. The clamping plate 12 slides on the limit rod 13, which helps limit the two clamping plates 12 to move only in relative directions, and no shaking occurs in other directions.

[0032] like Figure 3 As shown, a rubber plate 14 for clamping the battery is arranged inside the clamping plate 12 , and an anti-slip groove 15 is arranged on the surface of the rubber plate 14 .

[0033] An integrally formed limit strip 17 is disposed on the back of the rubber plate 14 , and a limit slot 16 for clamping the limit strip 17 is provided on the clamping plate 12 . Both the limit slot 16 and the limit strip 17 are provided with a strip-shaped structure.

[0034] This structural arrangement can make the position of the clamped battery more stable. After being clamped, the battery will not be offset in position until the two clamping plates 12 release the battery, and then the battery will fall from a certain height.

[0035] like Figure 1-2 As shown, the driving member includes a driving motor 5, a winding drum 6 arranged on the output shaft of the driving motor 5, a steel wire rope 9 connected to the moving plate 4 is wound on the winding drum 6, and the driving motor 5 is fixed on the top plate 3;

[0036] The driving motor 5 works to drive the winding drum 6 to rotate, so that the wire rope 9 on the winding drum 4 moves accordingly, thereby adjusting the height of the moving plate 4 connected to the wire rope 9.

[0037] The top plate 3 is provided with a first winding wheel 7 and a second winding wheel 8 for guiding the steel wire rope 9. The first winding wheel 7 is arranged on the top of the top plate 3, and two second winding wheels 8 are provided. The gap between the two second winding wheels 8 clamps the steel wire rope 9. The first winding wheel 7 and the second winding wheel 8 guide the steel wire rope 9 in a vertical state, so that the steel wire rope 9 has a better suspension effect on the movable plate 4. The steel wire rope 9 will not shift at the bent part, and the actual application effect is better.

[0038] like Figure 4 As shown, the telescopic rod 2 includes a telescopic sleeve rod 21 and a hand screw 22. A plurality of telescopic sleeve rods 21 are provided, and the plurality of telescopic sleeve rods 21 are sleeved between two adjacent telescopic sleeve rods 21. A hand screw 22 is provided near the bottom of the telescopic sleeve rod 21 located on the outside. The overall length of the telescopic sleeve rod 21 is locked by the hand screw 22. When testing the battery, the appropriate length can be adjusted according to actual needs, so that the top plate 3 on the top of the telescopic rod 2 is at a suitable height; scale lines 23 are evenly arranged on the telescopic sleeve rod 21, which can make the adjusted height more accurate and enable the user to know the height of the top plate 3 in time.

[0039] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
