Title:
POSITION SENSOR AND GEAR-SHIFTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/080353
Kind Code:
A1
Abstract:
A position sensor and a gear-shifting device. The position sensor is used for detecting an operating position of an operating component and comprises: a first detection element set (10) and a second detection element set (20) that each include at least two detection elements, and a detected body (30) that is detected by all the detection elements (11, 21) in the first detection element set (10) and the second detection element set (20) jointly. Detection areas corresponding to different relative positions of the detected body (30) are detected by all the detection elements (11, 12), so that the position sensor can output different pieces of code information, accordingly, the operating position of the operating component is detected, realizing the functions of single-point failure correction and two-point failure recognition; and the detection elements (11, 12) have physical position deviations in a relative position conversion direction, so that compared with qualifying code information recognized without physical position deviations, the qualifying code information recognized by the position sensor in a motion process of the detected body (30) is greatly reduced, thereby improving the detection efficiency.
