[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations:

[0028] See also Figure 1-Figure 6 A battery fixing structure includes a positioning frame 1, a battery shell 2 and a quick release rod 3. The positioning frame 1 is fixedly installed on a vehicle frame 4. The fixing method can be welding or by fasteners. As for the installation position of the positioning frame 1, as one of the options, its two ends can be respectively fixed on two pipes of the vehicle frame 4. If the pipe is cylindrical, two notches corresponding to the shape of the pipe can be opened on the positioning frame 1, so that the positioning frame 1 can be more adapted, stably and firmly fixed on the vehicle frame 4.

[0029] like Figure 4 As shown, in this embodiment, the positioning frame 1 includes a supporting body 11 for supporting the battery housing 2 and a first side wall 12 and a second side wall 13 arranged on both sides of the supporting body 11. For the supporting body 11, its upper surface is used to contact with the battery housing 2. When the ground of the battery housing 2 is a flat surface, the upper surface of the supporting body 11 can also be a flat surface to make the cooperation between the two more stable.

[0030] As one of the options, the first side wall 12 and the second side wall 13 are respectively formed by bending two sides of the support body 11. In this embodiment, one or more first mounting holes 15 are respectively opened on the first side wall 12 and the second side wall 13, and the positions of the first mounting holes 15 on the first side wall 12 correspond to the first mounting holes 15 on the second side wall 13 one by one, which are used for the insertion of the quick release rod 3.

[0031] like Figure 2 , Figure 3 , Figure 5 As shown, the two sides of the bottom of the battery housing 2 are respectively provided with extended walls 21, and the length and width of the extended wall 21 can be specifically selected according to actual needs. The form shown in the figure is one of the options.

[0032] In this embodiment, the spacing between the outer wall of the first side wall 12 and the outer wall of the second side wall 13 is W1, and the spacing between the inner walls of the two extension walls 21 is W2, W1 is less than or equal to W2. When setting specifically, it is only necessary to ensure that the two extension walls 21 can be loaded into the positioning frame 1. Through the cooperation of the extension wall 21 with the first side wall 12 and the second side wall 13, the battery housing 2 and the positioning frame 1 are self-positioned, which is the first step of installing the battery housing 2 on the positioning frame 1.

[0033] The extension wall 21 is provided with a second mounting hole 22 corresponding to the position of the first mounting hole 15. To facilitate the cooperation between the second mounting hole 22 and the quick release rod 3, in this embodiment, the extension wall 21 includes an opening 23 connected to the second mounting hole 22, so that when the battery housing 2 is assembled on the positioning frame 1 from above, the corresponding part of the quick release rod 3 can directly enter the second mounting hole 22 from the opening 23, so that the quick release rod 3 does not need to be disassembled and is always installed on the positioning frame 1, which is convenient for operation. The second mounting hole 22 and the opening 23 are combined to form a strip hole.

[0034] The structure of the quick release lever 3 can refer to the universal quick release lever for bicycles. In this embodiment, it includes an axis core 31, an end cap 32, a gasket 33 and an eccentric handle 34, wherein the axis core 31 is a rod-shaped component, and its position layout can refer to Figure 2 , Figure 3 As shown, it is specifically arranged at the two first mounting holes 15, and its two ends extend outside the two first mounting holes 15 respectively, so that when the battery housing 2 is installed on the positioning frame 1 from above, the shaft core 31 can directly enter the second mounting hole 22 through the opening 23.

[0035] The end cap 32 is fixed to one end of the shaft core 31 . In this embodiment, one end of the shaft core 31 is a threaded end, and the end cap 32 is threadedly installed at the threaded end of the shaft core 31 to facilitate the disassembly, replacement, and maintenance of the end cap 32 .

[0036] The end cap 32 is specifically arranged on the outer side of one of the extension walls 21, such as Figure 2 As shown, it is used to cooperate with the outer wall of the extension wall 21.

[0037] The gasket 33 and the eccentric handle 34 are arranged at the other end of the shaft core 31. In this embodiment, the gasket 33 can be movably assembled on the shaft core 31. The specific arrangement position can be referred to Figure 3 As shown, it is arranged on the outer side of another extension wall 21.

[0038] The end of the shaft core 31 may also be a threaded end, and a connecting shaft (refer to a universal quick release lever for bicycles) is threadedly assembled thereon, and the eccentric handle 34 is rotatably connected to the connecting shaft so that the eccentric handle 34 can rotate relative to the shaft core 31 .

[0039] The eccentric handle 34 includes an eccentric portion. When the eccentric handle is folded (pressed), the eccentric portion contacts the gasket 33 and pulls the shaft core 31 to move laterally, and the end cap 32 moves laterally accordingly, thereby shortening the distance between the end cap 32 and the gasket 33. After the eccentric handle 34 is folded, it itself is also positioned, so that the battery housing 2 can be effectively locked on the positioning frame 1; when the battery housing 2 needs to be removed, the eccentric handle 34 can be unfolded, the battery housing 2 can be directly taken out upwards, and the shaft core 31 can be directly detached from the opening 23.

[0040] In order to make the end cap 32 and the gasket 33 fit more closely with the extension wall 21, in this embodiment, a groove 24 is included on the extension wall 21, and the shape and size of the groove 24 can be adapted to the shape and size of the end cap 32 and the gasket 33, so that at least part of the end cap 32 and the gasket 33 can enter the groove 24, so as to limit the position of the end cap 32 and the gasket 33, making it difficult for them to move, thereby improving the positioning effect of the battery housing 2.

[0041] In this embodiment, the second mounting hole 22 is defined in the groove 24 .

[0042] In order to further improve the positioning effect of the battery housing 2, a positioning block can be additionally installed between the battery housing 2 and the vehicle frame 4 to fill the gap between the two.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
