ELECTROMAGNETIC SWITCH DEVICE

WIPO Patent Application WO/2020/215378

A1

Provided is an electromagnetic switch device, comprising a housing, a stator installed within the housing, and a rotor movable relative to the stator. The rotor comprises a coil, a support frame supporting the coil, and a connection member connected to the support frame and having a terminal end extending outside of the housing to connect an external component. The stator comprises two magnetic steel assemblies respectively located at two opposite sides of a coil winding plane of the coil, and the magnetic steel assemblies are disposed opposite to the coil, and the two magnetic steel assemblies form a magnetic circuit. The electromagnetic switch device provided in the present invention stacks the two magnetic steel assemblies in layers at two sides of an axial direction of the coil, after the coil is energized, the energized coil is under action of an electromagnetic force in a magnetic field, and the coil and the support frame move relative to the magnetic steel assemblies, so as to drive an external part to move vertically. In this way, the electromagnetic switch device provided by the present invention has a simple structure, uses parts easy to manufacture and assemble, and at a low cost.
