Title:
DISPLACEMENT SENSOR AND VEHICLE HEIGHT SENSOR
Document Type and Number:
Japanese Patent JP2021179407
Kind Code:
A
Abstract:
To provide a displacement sensor that increases a degree of freedom in being mounted to a structure and is compact and light, and to provide a vehicle height sensor using it.SOLUTION: A displacement sensor 1 includes oscillation means 3, a detection part 2, and a signal processing part 4. The detection part 2 has a bobbin 10, a detection coil 15, and a wire 20 obtained by twisting a metal wire. A high-frequency magnetic field is generated in a hollow part 11 of the bobbin 10 by the detection coil 15. For the wire 20, one end 20a is inserted into the hollow part 11 and the other end 20b is connected with a moving body 5. The wire 20 has at least one of magnetic permeability and conductivity, and has moderate flexibility and elasticity. The wire 20 is curved between the detection part 2 and the moving body 5. The moving body 5, a displacement direction 5b of the moving body, the wire 20, and the detection part 2 does not need to be disposed in a line, thus allowing for being mounted with a high degree of freedom.SELECTED DRAWING: Figure 1
