Title:
CLAPPING-TYPE BISTABLE MAGNETIC CIRCUIT STRUCTURE AND MAGNETIC LATCHING RELAY
Document Type and Number:
WIPO Patent Application WO/2022/152219
Kind Code:
A1
Abstract:
Provided are a clapping-type bistable magnetic circuit structure and a magnetic latching relay. The magnetic circuit structure comprises a coil (1), an L-shaped armature (2), an L-shaped yoke (3), and a magnetic steel (4); the L-shaped armature (2) is arranged on the side edge of the L-shaped yoke (3) after being rotated by 180 degrees and defines a frame-shaped contour together with the L-shaped yoke; preset first gaps are formed at joints of the L-shaped armature (2) and the L-shaped yoke (3) at two opposite diagonal corners of the frame shape; the L-shaped yoke (3) comprises a first yoke portion (31) and a second yoke portion (32) that form the L shape; the coil (1) is fitted on the first yoke portion (31) of the L-shaped yoke (3); one end of the magnetic steel (4) is connected to the first yoke portion (31) of the L-shaped yoke (3); the L-shaped armature (2) comprises a first armature portion (21) and a second armature portion (22) that form the L shape; and the first armature portion (21) is fitted on the other end of the magnetic steel (4) to move in a seesaw manner, so that the bistable magnetic circuit is formed between the magnetic steel (4), and the L-shaped armature (2) and the L-shaped yoke (3) which have asymmetric part structures; and excitation of the coil (1) is utilized to implement switching between two stable states of the bistable magnetic circuit.
