Problems solved by technology

However, the life of the rotary switch using the contact scheme is short. After long-term use, there will be poor contact between the moving contact piece and the static contact piece, and there is a risk of fracture and plastic deformation of the spring after reaching the fatigue life.

Abstract

The invention discloses a novel non-contact rotary switch and a method for realizing pulse output by using the same, the rotary switch comprises a stator part and a rotor part, the stator part comprises a shell and a resolving board arranged in the shell, the resolving board comprises a circuit board, and a magnetic conversion chip, a microprocessor, a power supply circuit and a driving circuit which are arranged on the circuit board; the rotor part comprises a rotating shaft arranged below the resolving plate, the rotating shaft is installed in the shell through a bearing, a cylindrical magnet is fixed to the top end of the rotating shaft, a first annular magnet and a second annular magnet are fixedly installed on the rotating shaft, an outer gear is fixedly installed on the rotating shaft above the second annular magnet, and an inner gear matched with the outer gear is arranged on the shell. The pulse generation mode of the rotary switch adopts a non-contact magnetoelectric conversion scheme, so that the rotary switch has higher reliability; damping is generated through suction force between the gears, and accurate positioning is achieved; aB signals with different phases are output according to different rotation directions and can be used for judging the rotation directions.

Description

technical field [0001] The invention relates to the field of rotary switches, in particular to a novel non-contact rotary switch and a method for realizing pulse output by using the same. Background technique [0002] The rotary switch is mainly used on the front of the instrument or the control panel of audio-visual equipment and household appliances. Its main functions are function switching, volume adjustment, speed adjustment, temperature adjustment, etc. The traditional rotary switch uses a moving contact, a static contact and a spring for positioning adjustment, and outputs pulse levels through the on-off of the moving reed and the static contact. However, the life of the rotary switch using the contact scheme is short. After long-term use, there will be poor contact between the moving contact piece and the static contact piece, and the risk of fracture and plastic deformation of the spring after reaching the fatigue life. Contents of the invention [0003] The tech...
