[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figure 1 As shown, an assembly structure for an electric vehicle controller box includes an electric vehicle frame 2, handlebars 3, seat 4, battery 5, and wheels 6. The handlebars 3 are mounted on one side of the electric vehicle frame 2. Two wheels 6 are rotatably connected to the lower end of the electric vehicle frame 2. The battery 5 is mounted in the middle of the electric vehicle frame 2. The seat 4 is located at the upper end of the electric vehicle frame 2. The controller box 1 is located below the seat 4 and is fixedly mounted on the side of the electric vehicle frame 2 near the battery 5, between the battery 5 and the rear wheel 6. This assembly structure for an electric vehicle controller box reduces cable length and solves the problem of excessively long and easily worn cables by fixing the controller box to the side of the electric vehicle frame near the battery and positioning it between the battery and the rear wheel. It also reduces the overall cost of the vehicle, enhances the protection of the controller, improves the safety of the electric vehicle, and extends its lifespan.

[0033] like Figure 2 and Figure 3As shown, the controller box 1 includes a charging port 11, a cover plate 12, and a base plate 13. The battery 5 is electrically connected to the charging port 11. The charging port 11 is located on one side of the cover plate 12. The base plate 13 is fixedly installed on the other side of the cover plate 12, and the cover plate 12 and the base plate 13 cover the controller 14. The controller 14 is electrically connected to the charging port 11.

[0034] like Figure 4 As shown, the charging port 11 includes a dustproof plate 111, a charging port body 112, and a power module 113. One end of the dustproof plate 111 is hinged to one end of the charging port body 112, and the other end of the charging port body 112 is fixedly connected to the power module 113. The power module 113 is electrically connected to the battery 5. When charging the electric vehicle, the dustproof plate 111 hinged to the charging port body 112 is opened, and the external charger plug is inserted into the charging port body 112. At this time, the charging port body 112 forms an electrical connection with the battery 5 through the power module 113 connected to it. The current is transmitted to the battery 5 through the charging port body 112 and the power module 113 to complete the charging. After charging is completed, the charger plug is unplugged, and the dustproof plate 111 automatically closes to cover the charging port body 112. The dustproof plate 111 can effectively prevent dust, moisture, and other impurities from entering the charging port body 112, reduce pollution inside the charging port, reduce the risk of short circuits, and extend the service life.

[0035] like Figure 4 As shown, a threaded hole 1121 is provided on each side of the charging port body 112, and a bolt is threaded into each threaded hole. The bolt is used to install the charging port body 112 on the cover plate 12.

[0036] like Figure 5 and Figure 7 As shown, the cover plate 12 includes a cover plate body 121 and two first mounting plates 122. The lower end of the cover plate body 121 is fixedly connected to the electric vehicle frame 2 through the two first mounting plates 122, and the two first mounting plates 122 are parallel to each other and facing each other.

[0037] like Figure 5 As shown, the cover plate body 121 has two reinforcing ribs 1211 in the middle.

[0038] When the controller box 1 is subjected to vibration, impact or load pressure during the operation of the electric vehicle, the reinforcing rib 1211 disperses the stress on the cover body 121 through its own structure, reduces the deformation or bending of the cover body 121 caused by external force, maintains the structural stability of the cover body 121, and thus ensures the safety of the internal cavity of the controller box 1 and the controller 14. The reinforcing rib 1211 can enhance the structural strength, ensure the safety of the internal controller, and adapt to different working scenarios.

[0039] like Figure 5 As shown, a toothed groove 1212 is provided on one side of the cover plate body 121, and the toothed groove 1212 is used to install the footrest plate of the electric vehicle.

[0040] like Figure 6 and Figure 7 As shown, the base plate 13 includes a base plate body 131, a second mounting plate 132 and a third mounting plate 133. One side of the cover plate body 121 is fixedly connected to the base plate body 131. The upper end of the base plate body 131 is fixedly connected to the second mounting plate 132. The two sides of the second mounting plate 132 are respectively fixedly installed in the electric vehicle frame 2. The lower end of the base plate body 131 is fixedly connected to the third mounting plate 133. The two sides of the third mounting plate 133 are also respectively fixedly installed in the electric vehicle frame 2.

[0041] like Figure 6 As shown, the controller box 1 also includes a controller 14. A cavity is formed between the base plate body 131 and the cover plate body 121. The controller 14 is installed inside the cavity, and its lower end is fixedly connected to the base plate body 131. The controller 14 is electrically connected to the battery 5 and the drive unit of the electric vehicle. The cavity is formed by the cover plate body 121 and the base plate body 131 to form a closed structure, isolating the controller 14 from the external environment. This prevents dust, moisture, and foreign objects from directly contacting the controller during driving and also reduces the direct impact of vehicle vibration on the controller. By installing the controller 14 in the cavity formed between the base plate body 131 and the cover plate body 121, a closed installation environment is provided, which can effectively block the entry of external dust, rainwater, and debris, reduce the risk of short circuits or malfunctions caused by contamination or moisture, ensure its stable operation, and extend its service life.

[0042] Assembly process of an electric vehicle controller box:

[0043] The base plate 131 is fixedly connected to the second mounting plate 132 and the third mounting plate 133 respectively. Then, the charging port 11 is assembled. The dustproof plate 111 is hinged to one end of the charging port body 112, and the other end is connected to the power module 113. The charging port body 112 is then fixed to one side of the cover plate 12 through the threaded hole 1121 and bolts. One side of the cover plate body 121 is fixedly connected to the base plate body 131 of the base plate 13 to form a cavity. The controller 14 is installed in the cavity, completing the overall assembly of the controller box 1. The lower ends of the two first mounting plates 122 of the cover plate 12 are fixedly connected to the electric vehicle frame 2 respectively. The two sides of the second mounting plate 132 and the two sides of the third mounting plate 133 of the base plate 13 are also fixedly installed in the electric vehicle frame 2 respectively, so that the controller box 1 is fixed under the seat 4. The power module 113 is electrically connected to the battery 5, and the controller 14 is electrically connected to the battery 5 and the electric vehicle drive unit. The toothed groove 1212 on one side of the cover plate body 121 is used to install the electric vehicle footrest plate, completing the assembly of the entire assembly structure.
