Problems solved by technology

[0002] Now, the electric handicapped rehabilitation scooters used by the disabled and the elderly have developed rapidly and have been widely used; while the current general electric handicapped scooters basically use variable resistors to generate speed adjustment signals, but Because the electric disabled rehabilitation scooter has relatively high requirements for speed regulation and direction control, the variable resistors in this electric disabled rehabilitation scooter will produce contact wear during the adjustment process, and its service life is only 1 million times , so it will reduce the reliability of vehicle safety, so this technology should not be widely used

Abstract

The invention discloses an electric speed governor for an electronic handicapped scooter. The electric speed governor comprises a rotating shaft arranged inside a substrate and an output end arranged outside the substrate; a magnetic steel permanent seat is arranged on the upper end of the rotating shaft; a magnetic steel is arranged in a fixed hole on the magnetic steel permanent seat, and is aligned with a Hall sensor on a printed circuit board (PCB) component; an upper cover is arranged outside the Hall sensor; a torsion spring is arranged outside the upper end of the rotating shaft; and when the rotating shaft rotates, a magnetic flux change can be transferred to the Hall sensor through the magnetic steel and then transferred to the PCB component, and a signal is output through related circuits of the PCB component and the output end of the substrate, so that the direction and speed of the electronic handicapped scooter can be changed. The electric speed governor has the advantages that the contact abrasion of the electronic handicapped scooter in a governing process is eliminated, the service life of the speed governor component is prolonged, and the speed governor component is still maintained to be normal after working for 5 million times, so that the vehicle safety is greatly improved.

Description

Technical field: [0001] The present invention relates to an electronic governor, in particular, the present invention relates to an electronic governor of an electric handicapped scooter. Background technique: [0002] Now, the electric handicapped rehabilitation scooters used by the disabled and the elderly have developed rapidly and have been widely used; while the current general electric handicapped scooters basically use variable resistors to generate speed adjustment signals, but Because the electric disabled rehabilitation scooter has relatively high requirements for speed regulation and direction control, the variable resistors in this electric disabled rehabilitation scooter will produce contact wear during the adjustment process, and its service life is only 1 million times , so it will reduce the reliability of vehicle safety, so this technology should not be widely used. Invention content: [0003] The technical problem to be solved by the present invention is...
