[0027] As Figures 1-3 and Figure 6 shown, the cover plate 2 and the battery shell 1 are connected through the connecting assembly 3, the threading hole 4 penetrates the middle part of the battery shell 1, and the battery pack 5 and the protection plate 7 are electrically connected through the wires, facilitating the power supply of the battery pack 5 and the threading operation of the end connecting wire of the battery pack 5.

[0028] As Figures 2-5 shown, the force receiving plate 81 and the first support sleeve 85 are fixedly connected with the force receiving column 83, the first damper 86 and the first buffer spring 87 are fixedly connected with the first support sleeve 85, the gear 89 is movably connected with the connecting shaft 88, the linkage column 810 is matched with the second moving hole 812, the gear teeth 811 are engaged with the gear 89, the linkage column 810 is fixedly connected with the second support sleeve 813, and the two ends of the second damper 814 are fixedly connected with the contact plate 815 and the second support sleeve 813 respectively, and the contact plate 815 is made of rubber, so as to facilitate the double damping effect during the impact of the cover plate 2.

[0030] The working principle of the utility model is that during the disassembly of the battery protection plate, the user disassembles the connecting assembly 3 between the battery shell 1 and the cover plate 2, and takes out the protection plate 7, and during the impact of the battery, the shock-absorbing rubber pad 9 and the shock-absorbing assembly 8 play the damping and buffering effect.

[0031] It should be noted that through the setting of the connecting assembly 3, when the protection plate 7 or the battery pack 5 needs to be disassembled, the user will pull the linkage plate 38 through the handle 39, drive the traction spring 310 to stretch, and the positioning pin 37 will be pulled out along the inside of the auxiliary hole 35 and the positioning groove 36.

Under the support of the auxiliary support plate 82, the first support sleeve 85 is driven to extrude the first damper 86 and the first buffer spring 87, so that the first damper 86 and the first buffer spring 87 are compressed to absorb the impact force. At the same time, during the descent of the force receiving column 83, the teeth 811 engage with the gear 89, driving the gear 89 to rotate along the outside of the connecting shaft 88, further engaging the teeth 811 along the outside of the linkage column 810, thereby driving the linkage column 810 to move upward along the inside of the second moving hole 812. Under the contact of the contact plate 815 with the force receiving plate 81, the second support sleeve 813 is then driven to extrude the second damper 814 and the second buffer spring 816, further absorbing the impact force, thereby achieving a secondary buffering effect and better protecting the battery and further protecting the protection plate 7 from damage to the nickel sheet caused by impact.

[0033] It should be noted that when the battery is impacted, the shock absorbing rubber pad 9 can also be used for protection to prevent the protection plate 7 from shaking and further improve the shock absorbing efficiency.

[0034] The above is only the preferred embodiment of the present application, and it should be noted that for ordinary skilled persons in the art, without departing from the principle of the present application, a number of improvements and refinements can be made, which should also be considered within the scope of protection of the present application.
