AI Technical Summary
The handlebars of existing electric tricycles have a fixed height and cannot be adjusted according to the driver's height, body type or driving habits. This leads to arm fatigue and shoulder pain during long-term driving, affecting driving safety and comfort. At the same time, the traditional locking structure is prone to wear and unstable clamping.
The clamping assembly includes a double-threaded rod and a clamping block. By rotating the threaded rod, the clamping block is driven to symmetrically clamp the first shaft of the handlebar. Combined with the cooperation of the convex rib and the groove, a stable lock is achieved, avoiding wear of parts.
The height of the armrest is adjustable to suit the needs of different drivers, improves locking stability, avoids wear and damage to parts, and enhances driving safety and comfort.
