Title:
HALL DISPLACEMENT SENSOR
Document Type and Number:
WIPO Patent Application WO/2021/093078
Kind Code:
A1
Abstract:
A Hall displacement sensor, comprising a first sliding block (10), a second sliding block (20), and an elastic member (70). The first sliding block (10) is slidably connected to the second sliding block (20). The first sliding block (10) and the second sliding block (20) have a gap therebetween in a sliding direction. The elastic member (70) is located in the gap. The elastic member (70) exerts an acting force in the sliding direction on the first sliding block (10) so that the first sliding block (10) abuts against the second sliding block (20). The Hall displacement sensor further comprises a magnetic member (40), a Hall chip (50), and a circuit board (60) electrically connected to the Hall chip (50). One of the magnetic member (40) and the Hall chip (50) is disposed on the first sliding block (10), and the other is disposed on the second sliding block (20). According to the Hall displacement sensor, the Hall chip (50) is disposed in a magnetic field generated by the magnetic element (40); in an automatic coupling process, a first coupling device is coupled to a second coupling device under the driving of a motor; the Hall chip (50) moves in the magnetic field, and the relationship between the displacement of the Hall chip (50) in the magnetic field and a sensing signal is established based on the Hall effect, thereby implementing displacement measurement.
