Angle sensor based on giant magnetoresistance chip

Abstract

The invention discloses an angle sensor based on a giant magnetoresistance chip, which structurally comprises a rotating shaft, a synchronizing wheel and an operation box, wherein the synchronizing wheel is arranged on the rotating shaft, the synchronizing wheel is connected with the rotating shaft, the rotating shaft is arranged on the operation box, the rotating shaft is in clearance fit with the operation box, the operation box is provided with a box body, a rotating shaft, a rear cover, a chip, a magnet and a stabilizer, and the rotating shaft is arranged in the box body. The rotating shaft is embedded with the box body, the magnet is installed on the rotating shaft, the magnet is connected with the rotating shaft, the stabilizer is installed on the box body, the stabilizer is supported on the rotating shaft in an abutting and buckling mode, the supporting area of the rotating shaft is increased, and the clamping block of the adjuster can be arranged at the bottom of the rotating shaft in an abutting and buckling mode through the adjusting assembly structure. The supporting points of the rotating shaft are further increased, the rotating shaft is wrapped by the stabilizer, the stabilizer limits the rotating shaft in the wrapping space, the shaking space of the rotating shaft is reduced, and the rotating shaft cannot be influenced by radial force and axial force and easily shakes.

Description

technical field [0001] The invention relates to the field of sensors, in particular to an angle sensor based on a giant magnetoresistance chip. Background technique [0002] The angle sensor based on the giant magnetoresistive chip is used to detect the angle. There is a hole in its body to fit the Lego shaft. When it is connected to the upper, the angle sensor will count once every time the shaft turns / turns. When turning in one direction, the count increases, and when the direction of rotation changes, the count decreases; [0003] The rotary shaft of the angle sensor is embedded in the box body, and there is no bearing support structure around it. If the radial force and axial force on the rotary shaft are too large when the rotary shaft rotates, the rotary shaft will have insufficient support due to insufficient supporting force. Shaking and deflection, and the rotary shaft is connected with the rotating shaft. When the rotary shaft shakes, it will affect the rotating s...

AI Technical Summary

Problems solved by technology

[0003] The rotary shaft of the angle sensor is embedded in the box, and there is no bearing support structure around it. If the radial force and axial force received by the rotary shaft are too large when the rotary shaft rotates, the rotary shaft will have insufficient support due to insufficient supporting force. Shaking and deflection, while the rotary shaft is connected to the rotating shaft, when the rotary shaft shakes, it will affect the rotating shaft, causing the overall rotating structure to shake and deflect, thereby reducing the accuracy of angle measurement
