US 2025/0137531 A1 · Electromagnet and Locking Arrangement With Electromagnet and Spring-pretensioned Latching Means

Abstract

A locking arrangement has an electromagnet having an armature and an armature rod, a component which is rotatable about an axis in a first direction of rotation and in an opposite second direction of rotation and has circumferential engagements, a latching means with a restoring surface, which is connected to the armature rod and is adjustable between a latching position and a release position, a spring element which pretensions the latching means into the latching position and allows the latching means to be restored into the release position. The rotatable component can act on the restoring surface during rotation in the second direction of rotation to bring the latching means into the release position counter to the spring force of the spring element.

Dependent claims

An electromagnet for a locking arrangement, the electromagnet comprising:

an armature, which can be fixed in at least one stable and permanent-magnetic end position;
an armature rod;
a selectively energizable coil for adjusting the armature;
and
a spring element which is supported at one end on a first bearing base and at another end on a second bearing base, which is mounted movably relative to the first bearing base;
wherein the second bearing base is movable relative to the armature, the armature rod, or both the armature and the armature rod i) while the selectively energizable coil is not energized, ii) during a stable and permanent-magnetic end position of the armature, or iii) both i) and ii).
