Electric self-priming lock

Abstract

The invention relates to the field of electric locks, and discloses an electric self-priming lock. A locking motor is fixed to a base, an output shaft of the locking motor is engaged with one side ofa gear piece, the other side of the gear piece is rotatably connected with the base, one end of a pull rod is rotatably connected with the other side of the gear piece, and the other end of the pull rod is tangent to one end of a resisting block all the time before the electric self-priming lock is unlocked; the resisting block, the pull rod, a jaw locking block, a limiting block and an unlockingpiece are rotatably connected with the base respectively, and the gear piece, the pull rod, the jaw locking block and the limiting block are rotatably interlocked in sequence; and an output shaft of an unlocking motor is connected with one end of the unlocking piece through wire drawing, and the unlocking piece, the limiting block and the resisting block are rotatably interlocked. Compared with the prior art, the electric self-priming lock has the advantages of reasonable structural design, safety and reliability, and no matter which state a door lock is in, when the locking motor is damaged,the electric self-priming lock can be manually unlocked.

Description

technical field [0001] The invention relates to the field of electric locks, in particular to an electric self-priming lock. Background technique [0002] At present, bus doors and passenger car doors are not locked with locks, and the bus is completely pulled by the cylinder to hold the door. If the cylinder is cut off or leaks, the door can be opened automatically, which is very unsafe. Present passenger cars mainly rely on the lifting and self-locking of the doors. If the lifting mechanism is damaged, the doors will also open automatically, which is also very unsafe. And these two kinds of car doors all can't manually close the car door when the car door driving mechanism is damaged, in order to improve the safety and convenience of the car door, researchers in the field mainly put the object of study on the structure of the car door lock. Contents of the invention [0003] Purpose of the invention: Aiming at the problems existing in the prior art, the present inventio...

Problems solved by technology

[0002] At present, the doors of buses and passenger cars are not locked with locks. The doors of buses are completely held by cylinders. If the cylinder fails or leaks, the doors can be opened automatically, which is very unsafe.

The current passenger car mainly relies on the door to lift and lock itself. If the lifting mechanism is damaged, the door will automatically open, which is also very unsafe.
