[0002] Electric vehicles (EVs) are electrically powered vehicles. They use batteries as their energy source and utilize components such as controllers and motors to convert electrical energy into mechanical motion, controlling the current flow to change speed. EVs are widely used, aligning with national energy conservation and environmental protection trends and significantly facilitating short-distance transportation. Headlights are a crucial component of EVs. They consist of an upper and lower housing. The upper housing, which typically contains the lampshade and lens, protects the internal lighting components from external influences and ensures proper operation. It also focuses the tube box and wires, ensuring the lighting effect and position. The lower housing, located opposite the upper housing, primarily provides support and fixation, ensuring the lamp is securely mounted on the EV. It contains electronic components and wiring ports for connecting to the power supply and control circuits. After assembly, the lower housing and upper housing are fixed together, making assembly and disassembly inconvenient. Consequently, the relative positions of the upper and lower housings are fixed and cannot be adjusted. This prevents EV users from adjusting the headlight's position according to their specific usage, impacting the headlight's adaptability.
