Title:
ELECTROMAGNETIC DRIVING UNIT AND RELAY
Document Type and Number:
WIPO Patent Application WO/2024/012196
Kind Code:
A1
Abstract:
The present disclosure provides an electromagnetic driving unit and a relay. The electromagnetic driving unit comprises a framework (4), a coil (5), a moving attraction member, and a static attraction member; the coil (5) is wound on the framework (4); the framework (4) is provided with an inner hole (41); the moving attraction member is disposed in the inner hole (41); and the static attraction member is disposed at one end of the inner hole (41) and opposite to the moving attraction member. Taking a plane perpendicular to the axial direction of the inner hole (41) as a projection surface, the area of the orthographic projection of the moving attraction member on the projection surface is a first projection area, the area of the orthographic projection of the static attraction member on the projection surface is a second projection area, the second projection area being greater than the first projection area. In the present disclosure, the static attraction member can effectively absorb leakage flux in a magnetic circuit, and therefore, the electromagnetic attraction force of the electromagnetic driving unit is increased.
