Rocker for electric wheelchair

Abstract

The invention discloses a rocker for an electric wheelchair. The rocker comprises a base. The base is provided with a square horizontal end, a first annular body and a second annular body. A metal rod is vertically arranged in the second annular body penetrating the base. A fixing seat is arranged inside the second annular body. The lower end of the metal rod penetrates the fixing seat and provided with an annular sleeve. A magnet is mounted in the annular sleeve. The lower surface of the annular sleeve is of a mesh structure. A horn-shaped lantern ring sleeves the upper portion of the metal rod, and the horn opening of the lantern ring faces downwardly. A spring and fixing ring are sequentially arranged above the lantern ring. The rocker for the electric wheel chair has the advantages that the trajectory of the metal rod of the rocker is a perfect circle during rocking, turning reliability is enhanced, the rotation amplitude is limited at the same time, and direction free clearance and losing can be prevented.

Description

technical field [0001] The invention relates to a rocker for an electric wheelchair. Background technique [0002] During the manufacturing process of electric wheelchairs, it is necessary to install rockers for electric wheelchairs. The rockers for electric wheelchairs are used to control the forward and turning of wheelchairs. Rotation, in the existing rocker device for electric wheelchairs, there is no limit mechanism in the base, it is difficult for the rocker for electric wheelchairs to maintain a regular 360-degree rotation, resulting in a rotation track that is not a perfect circle, which affects the wheelchair direction control. In addition, there is a magnet at the end of the metal rod of the magnetic rocker. The magnet must generate electromagnetic induction with the circuit board to control the movement of the wheelchair. In the prior art, the outer surface of the magnet is exposed, which is easy to accumulate dust and affects the electromagnetic induction. . ...
