DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The utility model provides Figure 1-3 The battery box installation device of the electric bicycle shown in the figure includes a carrying box body 1 and a battery 2. The battery 2 is slidably sleeved inside the carrying box body 1. A locking plate 3 and a fixing bolt 4 are provided on the top of the battery 2. The locking plate 3 is fixedly installed on the top of the carrying box body 1 by the fixing bolt 4. The bottom of the locking plate 3 is fixedly connected to a rubber gasket 53 for protecting the battery 2. Under the action of the fixing bolt 4, the locking plate 3 can make the rubber gasket 53 squeeze and limit the battery 2, so that the battery 2 is stably installed inside the carrying box body 1. By removing the locking plate 3, the battery 2 can be directly removed and replaced. A buffer component 5 for buffering the battery 2 is provided at the bottom of the inner cavity of the carrying box body 1. The buffer component 5 includes a carrying plate 51, a buffer spring 52 and a damping component 5 4. The supporting plate 51 is slidably sleeved on the inside of the supporting box body 1, and the top of the supporting plate 51 is squeezed and fitted with the battery 2. The buffer spring 52 is located at the bottom of the supporting plate 51, and there are multiple buffer springs 52 at the bottom of the supporting plate 51. When installing the battery 2, the buffer spring 52 can stably support the battery 2 through the supporting plate 51, and there is a certain squeezing force between the top of the battery 2 and the rubber gasket 53, thereby ensuring the stability of the installation of the battery 2. The buffer spring 52 provides an elastic buffering force to the battery 2 through the supporting plate 51. The damping component 54 is arranged between the supporting plate 51 and the supporting box body 1. Under the action of the damping component 54, the buffer spring 52 can stably buffer and protect the battery 2 through the supporting plate 51.

[0026] In particular, the damping assembly 54 includes a slider 541 and a damping block 542. The slider 541 is slidably engaged with the side of the carrier plate 51, and the damping block 542 is embedded in the interior of the carrier box body 1. The damping block 542 is provided with a recessed portion on the side facing the slider 541. When the buffer spring 52 buffers the battery 2 through the carrier plate 51, the friction resistance between the slider 541 and the damping block 542 can improve the stability of the buffering of the carrier plate 51, and as shown in FIG. Figure 3 As shown, when the slider 541 slides up and down relative to the recessed portion of the damping block 542 , the damping force thereof can be increased, and the end of the slider 541 fits in contact with the damping block 542 .

[0027] Furthermore, a mounting hole is provided on the inner wall of the carrying box body 1, and the damping block 542 is slidably sleeved inside the mounting hole. A limit block 545 for limiting the slider 541 is fixedly connected to the top of the inner wall of the mounting hole. A sealing plate 543 is provided on the side of the carrying box body 1. The side of the damping block 542 facing away from the slider 541 is fixedly connected to the sealing plate 543. A connecting bolt 544 is provided on one side of the sealing plate 543. The sealing plate 543 can seal the mounting hole and install the damping block 542. By removing the connecting bolts 544, the damping block 542 can be removed, and the slider 541 can be directly used to drive the connecting block 546 to separate from the supporting plate 51, and then the supporting plate 51 can be installed or removed. The sealing plate 543 is fixedly connected to the supporting box body 1 through the connecting bolts 544, and the side of the slider 541 facing away from the damping block 542 is fixedly connected to the connecting block 546. A connecting groove is provided on the side of the supporting plate 51, and the outer wall of the connecting block 546 is slidably connected to the inner cavity of the connecting groove.

[0028] Furthermore, the bottom of the supporting plate 51 is fixedly connected to a first limit seat 55, and the bottom of the inner wall of the supporting box body 1 is fixedly connected to a second limit seat 56. The ends of the buffer spring 52 are slidably connected to the first limit seat 55 and the second limit seat 56 respectively. The top of the second limit seat 56 is fixedly connected to a support rod 57 for limiting the descending distance of the first limit seat 55. The top of the support rod 57 is fixedly connected to a rubber block 58. The support rod 57 and the limit block 545 can cooperate to limit the distance that the supporting plate 51 slides up and down, so as to avoid excessive impact on the supporting box body 1, which causes the supporting plate 51 to move too far and cause damage to the components on the inner wall of the supporting box body 1.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
