AI Technical Summary
Technical Problem
In existing electric mobility scooter throttle control solutions, the metal reset structure is prone to fatigue and decay after prolonged use, leading to throttle control attenuation or loosening, which affects driving safety.
Method used
An angle detection device is adopted, including a housing, PCB board, rotating parts, magnet and AMR magnetoresistive sensor. The angle is detected by the rotation of the magnet, and a reset component is used to assist the rotating parts in resetting, so as to avoid fatigue of the metal structure.
Benefits of technology
It effectively avoids fatigue degradation of the metal structure, ensures the stability and safety of throttle control, and improves driving reliability.

Abstract
The application relates to an angle detection device. The angle detection device is configured to rotate a rotating member to drive a magnet to rotate. When the magnet rotates, a magnetic field generated by the magnet also rotates. An AMR magnetoresistive sensor measures the rotation angle of the magnetic field to reflect the rotation angle of the rotating member. The rotating member also presses a reset assembly to compress the reset assembly when the rotating member rotates. The rotating member is reset under the action of the reset assembly when the rotating member is released.
