Abstract

The invention discloses a rotating disc type sensing element with a plurality of unevenly distributed magnet blocks, belongs to the technical field of providing signals through magnetic induction, and in particular relates to the technology of providing a control signal through multi-point position magnetic induction on a rotating part. A plurality of permanent magnets distributed annularly are fixedly arranged on a rotating disc, and the spacings between the plurality of permanent magnets are different; the adjacent permanent magnets are opposite in magnetic polarity on one surface of the rotating disc; in other words, the distribution manner of the magnetic polarities of all permanent magnets on one surface of the rotating disc are pole N, pole S, pole N...; and a hall is arranged in a position in the vicinity of the permanent magnets. The rotating disc type sensing element with the plurality of unevenly distributed magnet blocks has the following advantages that with the opposite N-S distribution manner of the magnetic polarities of the adjacent permanent magnets, the hall is capable of obtaining a rectangular wave signal, thereby facilitating digital processing of the signal; and as the spacings between the plurality of permanent magnets are different, the rectangular wave signal is capable of indicating the positions of the permanent magnets on the rotating disc; and therefore, the uses of different rectangular waves are determined.

Description

technical field

[0001] The invention belongs to the technical field of providing signals by magnetic induction, and in particular relates to the technology of providing control signals by multi-point magnetic induction on a rotating component. Background technique

[0002] The Chinese patent 201020295192.0 "Claw Type Torque Sensing Device" applied by Yebao Vehicle Material Industry (Kunshan) Co., Ltd. discloses a sensing device for power-assisted bicycles. The sensing device includes a magnetic part and an elastic part to sense the torque. sensing device. After a long time of use, the change of the elastic coefficient of the elastic member will lead to changes in the sensing signal and the control effect of the controlled motor, and the power-assisted effect will not match the power-assisted needs of people. Moreover, the design structure of the elastic member is complex and the manufacturing cost is high.
