Description

Technical Field

A circular through hole is provided at the bottom of the handle, and the positioning button passes through the handle through the circular through hole and is slidably connected to the handle. The tension spring is sleeved on the outer surface of the positioning button, one end of the tension spring is fixedly connected to the positioning button, and the other end is fixedly connected to the inner wall of the handle. The gear is fixedly connected to the connecting rod. When in use, after the handle is rotated to raise the vehicle to a suitable speed, the positioning button is pressed by the thumb to clamp the top of the positioning button into the gear teeth of the gear, so that the handle and the connecting rod cannot rotate relative to each other, thereby avoiding the reverse rotation of the damping spring, which requires the user's wrist to resist all the time, affecting the user's driving of the battery vehicle.

[0004] The speed control device of the above patent and existing scooters is implemented by a single rotating handle. This structure is generally used to control a single hub motor, but it is impossible to perform power partition control for a vehicle with a dual hub motor. Utility Model Content

[0011] Specifically, the side wall of the first step is provided with an external thread and is threadedly connected to a limiting ring, and the limiting ring and the step surface of the first step clamp the toggle ring to form a limit for the toggle ring.

[0012] Preferably, the holding sleeve is a cylindrical structure with a concave cavity, and is rotatably sleeved on the second step.

[0013] Specifically, a support bearing is provided between the gripping sleeve and the side wall of the second step, and the two are rotatably connected via the support bearing.

[0014] Specifically, a return spring is provided between the gripping sleeve and the side wall of the second step, and the two return to their original positions by the rotational elastic force exerted by the return spring.

[0015] Preferably, a group of mutually cooperating limit blocks is provided between the end of the toggle ring and the first step, and between the end of the gripping sleeve and the second step.
