[0023] 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.

[0024] See also Figure 1-7 In the embodiment of the present invention, a side door device for a side-pull battery includes an upper plate 1 and a lower plate 2. The combination of the upper plate 1 and the lower plate 2 constitutes the main body of the overall structure of the side door device, which can well seal the opening for placing or removing the battery, and has a good sealing effect. In order to take into account both lightweight and strength, the thickness of the upper plate 1 is smaller than that of the lower plate 2. A reinforcing plate 8 is fixedly installed on the lower plate 2, and a snap plate 9 connected to the vehicle body is installed at both ends of the reinforcing plate 8. The reinforcing plate 8 strengthens the relationship between the two snap plates 9, so that the installation of the snap plates 9 is more stable. An adjusting component is installed on the lower plate 2, and the adjusting component includes a fixed round block 12 installed on the lower plate 2, and a limited block 10 is movably installed inside the fixed round block 12. The outer surface of the fixed round block 12 is provided with a threaded hole 121 that runs from the outside to the inside, and an adjusting The internal thread of the threaded hole 121 of the joint bolt 11 is matched with the external thread on the adjusting bolt 11. In order to prevent the friction generated by the shaking of the battery during the operation of the vehicle from causing the threaded contact position of the limit block 10 to move, an adjusting bolt 11 is provided. The limit block 10 is tightened by the adjusting bolt 11 to prevent loosening. The interior of the fixed round block 12 is provided with an internal thread, and a screw 13 is installed inside the limit block 10. The outer surface of the limit block 10 is formed with an external thread, and the external thread on the limit block 10 is matched with the internal thread on the fixed round block 12. The screw 13 is rotated and welded on the limit block 10, and the limit block 10 is driven by the screw 13 to rotate synchronously. At this time, since the position of the fixed round block 12 is fixed and cannot rotate, when the limit block 10 rotates, it will move forward or backward, realizing the position change of the limit block 10, thereby limiting the position of the battery.

[0025] See also Figure 1-3In one embodiment, in this embodiment, preferably, a notch is provided on the upper plate 1 for facilitating the insertion of the hand, and a sheath 7 is installed on the side of the notch to protect the hand from being easily injured during insertion. After the hand is inserted into the notch, the upper plate 1 can be opened conveniently, thereby completing the removal or insertion of the battery.

[0026] See also Figure 1-3 In one embodiment, in this embodiment, preferably, a charging door 6 is also installed on the upper plate 1. By inserting the external power cord into the charging door 6, a direct charging method can be compatible, avoiding the need to remove the internal battery.

[0027] See also Figure 1-4 In one embodiment, in this embodiment, preferably, an upper mounting plate 3 is provided on the upper plate 1, and a plurality of reinforcing ribs 4 are installed between the upper mounting plate 3 and the upper plate 1. A protruding structure 31 is provided at both ends of the upper mounting plate 3, and the protruding structure 31 is used to install a buffer pad 5, wherein the upper mounting plate 3 is used to limit the upper part of the side door device, and the strength is improved by the reinforcing ribs 4. The protruding structure 31 is used to install the buffer pad 5, and the buffer pad 5 is overlapped on the vehicle body and installed to prevent the side door device from shaking.

[0028] The working principle and usage process of the utility model are as follows: when in use, the buffer pad 5 and the snap plate 9 installed on the upper mounting plate 3 are fixed to the vehicle body by the upper and lower clamping method. When removing the side door device from the vehicle body, the operator puts both hands on the notch left in the upper plate 1, contacts the cover 7 and lifts and rotates the side door device to achieve the separation of the buffer pad 5 and the snap plate 9 from the vehicle body. Since the notch can accommodate both hands and the lightweight design is adopted, the operation is labor-saving and convenient without the assistance of tools.

[0029] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0030] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent modifications made according to the scope of the claims of the present application are within the scope of protection of the claims of the present application.
