Abstract

The embodiment of the invention provides an angle detection device. The angle detection device comprises a fixed part and a rotating part, wherein the length direction of the fixed part is parallel tothe rotating axial direction of the rotating part, and the rotating part can rotate in the circumferential direction of the rotating part relative to the fixed part; X detection elements are arrangedon the surface, facing the rotating part, of the fixed part at intervals in the length direction of the fixed part, wherein X is an integer larger than or equal to 1; in the circumferential directionof the rotating part, 2<X> magnetic piece sets are arranged on the rotating part at intervals; each magnetic piece set comprises X magnetic pieces; the X magnetic pieces in each magnetic piece set are arranged at intervals along the length direction of the rotating part, and each magnetic part corresponds to different detection element positions; and the polarity combinations of the magnetic pieces in different magnetic piece sets are different. According to the technical scheme provided by the embodiment of the invention, the polarity combination of each magnetic piece in different magneticpiece sets is detected, the detection of the preset angle of the rotation of the rotating part is realized, and the preset angle can be set by changing different arrangement modes of the magnetic piece groups.

Description

technical field [0001] The invention relates to the technical field of mechanical detection, in particular to an angle detection device. Background technique [0002] In the application scenario of detecting the preset specific rotation angle of the rotating body, sensors such as magnetic encoders, photoelectric encoders, and resolvers can be used to achieve the purpose of detection. [0003] However, the above-mentioned sensors currently used have limitations in use. For example, magnetic encoders generally can only be placed on the shaft end of the rotating body for measurement, and there are limitations in the selection of installation positions, and the scope of application is small. Contents of the invention [0004] In view of the above problems, an embodiment of the present invention is proposed to provide a new angle detection device, which uses another new method to detect the preset specific rotation angle of the rotating body, so as to improve the scope of appli...
