Electric lock

Abstract

The invention relates to the field of electric locks, and discloses an electric lock. The electric lock comprises a base, a locking motor, a gear piece, a driving block, a shifting rod, a jaw lockingblock, a limiting block, an unlocking piece and an unlocking motor, wherein the locking motor is fixed to the base, an output shaft of the locking motor is meshed with one side of the gear piece, theother side of the gear piece is rotationally connected with the base, and the driving block is rotatably connected with the other side of the gear piece; the shifting rod, the jaw locking block, the limiting block and the unlocking piece are all rotatably connected with the base, and the driving block, the shifting rod, the jaw locking block and the limiting block are rotationally connected in sequence; and an output shaft of the unlocking motor is connected with one end of the unlocking piece through a pull wire, and the unlocking piece, the limiting block and the driving block are rotationally connected. Compared with the prior art, the electric lock can be electrically locked and can be manually locked, the structural design is reasonable, safety and reliability are achieved, the energyconsumption is low, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of electric locks, in particular to an electric 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 invention provides an...

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.
