Cabin door electromagnetic lock for aviation

Abstract

The invention relates to the technical field of electromagnetic lock manufacturing, in particular to a cabin door electromagnetic lock for aviation. The cabin door electromagnetic lock comprises a main engine electronic loop device used for producing currents, a magnetizer communicated with the main engine electronic loop device, and armature fixed into a cabin door, wherein an electrifying switch used for controlling on-off of the currents produced by the main engine electronic loop device is arranged in the main engine electronic loop device, a copper coil used for generating magnetic force is arranged in the magnetizer, and the armature is used for being attracted by the magnetizer under the effect of the magnetic force. According to the cabin door electromagnetic lock, the copper coil is used for replacing an electromagnet, the electrifying switch adjusts magnitude of the currents and on-off of the currents to control the size and existence of a magnetic field of the magnetizer, and electromagnetic attracting lock force can be adjusted and controlled conveniently. Moreover, the structure design gap of a locking mechanism does not need to be reserved, the structural gap when the cabin door is in a closed state is reduced, and the problem that when the cabin door is closed, due to rigid impact of the locking mechanism, the structure is damaged is avoided.

Description

technical field [0001] The invention relates to the technical field of electromagnetic locks, in particular to an electromagnetic lock for aviation cabin doors. Background technique [0002] The aviation cabin door should have the function of opening and closing. When the cabin door is in the closed state, the locking mechanism is required to provide a locking force to act on the cabin door to overcome various force factors such as gravity, aerodynamic force and frictional resistance of the cabin door, so that the cabin can be closed. The door remains in a stable closed state; when the hatch is opened, the locking force of the locking mechanism must be released, and the hatch is safely opened under the action of the driving force provided by the outside. [0003] The existing cabin door locking mechanism adopts a mechanical locking mechanism, which has the following defects: [0004] 1. When the hatch is closed, there will be a rigid collision between the mechanical structu...

AI Technical Summary

Problems solved by technology

[0004] 1. When the hatch is closed, there will be rigid collision between the mechanical structures, which is prone to structural damage such as fatigue cracks and lock spring failure; 2. The mechanical locking mechanism needs to reserve a structural design gap to realize the locking and unlocking functions , so there will be a certain structural gap when the hatch is closed; 3. The locking force of the mechanical locking mechanism will cause adjustment difficulties or even unadjustable
