The seat barrel 120 is arranged in a square structure, and the chamfer surface means that the connection between two planes of the inner wall of the seat barrel 120 is not direct, but is connected and transited through the chamfer surface. Correspondingly, the vertical edge of the power battery 110, which is matched with the chamfered surface, is also chamfered. After the power battery 110 is mounted on the seat barrel 120, the power battery 110 is matched with the chamfered surface in the seat barrel 120 through the chamfer, so that the power battery 110 is gradually mounted in the seat barrel 120, and the accurate mounting of the power battery 110 is ensured.

Meanwhile, the matching of the chamfer and the chamfer surface can also prevent the power battery 110 from being reversely arranged in the seat barrel 120. When the power battery 110 is installed, the chamfer of the power battery 110 can be directly aligned with the chamfer surface of the seat barrel 120 for installation, so that the accurate installation of the power battery 110 is ensured; if the chamfer of the power battery 110 is not aligned with the chamfer of the seat barrel 120, it indicates that the power battery 110 is reversely mounted and the direction of the power battery 110 needs to be adjusted.

The first fool-proof rib 124 can serve the purpose of preventing the reverse installation of the power battery 110. When the power battery 110 is mounted on the seat barrel 120, the first fool-proof rib 124 can abut against the chamfer of the power battery 110, and at this time, the mounting position of the power battery 110 is correct. If the power battery 110 is reversely installed, the first fool-proof rib 124 will contact with the bottom surface of the power battery 110 to block the power battery 110, so that the power battery 110 cannot be installed in the seat barrel 120. Therefore, whether the power battery 110 is reversely mounted or not can be judged at the opening of the seat barrel 120, and a fool-proof effect is achieved.

Furthermore, the first fool-proof rib 124 can also guide the installation of the power battery 110 in the seat barrel 120. After the installation direction of the power battery 110 is correct, the power battery 110 can gradually move downwards to be installed in the seat barrel 120 according to the first fool-proof rib 124, so that the power battery 110 is pre-guided, the displacement of the power battery 110 is limited, and the plug-in base 111 of the power battery 110 is accurately matched with the discharge base 131.

That is, the second fool-proof rib 125 is provided on the planar inner wall of the tub 120. Optionally, a second fool-proof rib 125 is disposed on at least one planar inner wall of the seat barrel 120. In this embodiment, the second fool-proof rib 125 is only disposed on one planar inner wall of the seat barrel 120. After the power battery 110 is mounted on the seat barrel 120, the second fool-proof rib 125 can abut against the side surface of the power battery 110.

It should be noted that the structure and the working principle of the second fool-proof rib 125 are substantially the same as those of the first fool-proof rib 124, and are not repeated herein. Optionally, the number of the second fool-proof ribs 125 is multiple, and the inner wall of the same plane is provided with a plurality of second fool-proof ribs 125 at intervals, or the second fool-proof ribs 125 are respectively provided on the inner walls of the planes.

The power installation structure 100 of the present disclosure realizes that the power battery 110 is inserted and pulled in the seat barrel 120 by the insertion and pulling connection of the insertion base 111 at the bottom of the power battery 110 through the discharge base 131, and a user can realize the electrical connection of the power battery 110 and the discharge base 131 by installing the power battery 110 in the seat barrel 120 or removing the seat barrel 120, without electrically connecting the power battery 110 outside the seat barrel 120 through the flexible connector 1312, simplifying the assembly and disassembly steps of the power battery 110, and facilitating the use. Meanwhile, the discharging base 131 is further provided with a guide post, and the guide post can be in contact with a guide hole of the plugging base 111 to automatically align the position of the power battery 110, so that the plugging base 111 can be accurately connected with the discharging base 131.

Moreover, a fool-proof component, specifically, a matching of the chamfer surface and the chamfer, a first fool-proof rib 124 and a second fool-proof rib 125, is further disposed on the seat barrel 120. Thus, after the power battery 110 is mounted on the seat barrel 120, the chamfer surface is matched with the chamfer, and the first fool-proof rib 124 and the second fool-proof rib 125 are used for judging whether the power battery 110 is reversely mounted at the opening of the seat barrel 120, so that the fool-proof function is achieved. If the power battery 110 is reversely mounted, the chamfered surface does not correspond to the chamfer, and the first fool-proof rib 124 and the second fool-proof rib 125 can also block the power battery 110 from being placed in the seat barrel 120, indicating that the orientation of the power battery 110 needs to be adjusted when the power battery 110 is reversely mounted.
