Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, a self-resetting mechanism for improving the measurement accuracy of an angle sensor comprises an upper shell 2, a lower shell 3, a fastener 7, a magnet 5 and a rotating shaft 4, wherein the upper part of the upper shell 2 is connected with a circuit board 1 through the fastener 7, the magnet 5 is arranged in the middle of the rotating shaft 4, an elastic piece 6 is arranged outside the rotating shaft 4, the elastic piece 6 is fixed between the lower shell 3 and the rotating shaft 4, a rotating shaft fixing hole 401 is arranged in the middle of the rotating shaft 4, and the circuit board 1 is connected with a wire harness 8;
the rotating shaft fixing hole 401 is used for connecting an external connecting rod, and when the external connecting rod rotates, the rotating shaft 4 is driven to rotate, and meanwhile, the magnet 5 is driven to rotate.
Specifically, the elastic member 6 includes a torsion spring.
In particular, the fastener 7 comprises a fastening screw.
In this structure, torsion springs are fixed to the lower case 3 and the rotary shaft 4, respectively. When the external link fixed to the rotation shaft fixing hole 401 is rotated, the rotation shaft 4 is simultaneously rotated, so that the magnet 5 fixed to the rotation shaft 4 is rotated therewith. The magnetic signal is converted into an electrical signal by the hall chip.
Because there is the assembly between outside connecting rod and the pivot 4, there is assembly error inevitable, also has the damage after long-time the use, leads to the risk of relative not hard up. The structure is added with the torsion spring, the rotating shaft always has an acting force in the opposite direction under the action of pre-tightening the torsion spring, and the rotating shaft 4 is tightly attached to the external connecting rod, so that the problem of low precision caused by installation is solved.
In summary, according to the self-resetting mechanism for improving the measurement accuracy of the angle sensor, the torsion spring mechanism is used for pre-tightening the rotating shaft of the angle sensor in real time, so that the rotating shaft is constantly attached to the direction of the starting point in the rotating process, the dislocation and the like caused by the reciprocating rotation of the rotating shaft are avoided, and the measurement accuracy of the sensor is improved.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the teachings of this invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
