Description

Technical Field

[0001] This utility model relates to the field of electric two-wheeled vehicle technology, and in particular to an electric vehicle handlebar stem structure and an electric vehicle. Background Technology

[0002] In the electric two-wheeler industry, the basket fork, also known as the headlight fork, is a key component used to mount and secure the front basket. Its main function is to connect the basket to the frame. The basket fork is typically designed to be mounted on the seat tube at the top of the front fork. In existing technology, the basket fork is clamped between the seat tube and the mounting nut by a clamping mechanism. However, this method has an inherent design flaw. As the mounting nut rotates to lock, it causes the basket fork to rotate synchronously in the same direction. After the mounting nut is fully tightened, the basket fork's angle will shift, no longer facing directly forward of the frame. This misalignment can cause components mounted on the basket fork, such as the basket and headlight, to become misaligned, leading to inconvenience in vehicle use and even potential safety hazards.

[0003] To ensure the correct angle of the basket forks and the standardization and consistency of the vehicle's appearance, a secondary adjustment is usually performed using tools such as a hammer after the basket forks are tightened. This reduces production efficiency and increases the overall manufacturing cost. Moreover, the adjustment operation is highly dependent on the operator's experience, and visual inspection is difficult to be precise, resulting in possible angle deviations for each product and poor product consistency.
