Electric lock

Abstract

The invention relates to the field of electric locks, and discloses an electric lock. A locking motor is fixed to a base, an output shaft of the locking motor is engaged with one side of a gear piece,the other side of the gear piece is rotationally connected with the base, and a driving block is rotationally connected with the other side of the gear piece in a rotation mode; a transition block, atoggle rod, a jaw lock block, a limiting block and an unlocking piece are all rotatably connected with the base, and the driving block, the transition block, the toggle rod, the jaw lock block and the limiting block are sequentially rotationally linked; and an output shaft of an unlocking motor is connected with one end of the unlocking piece through a drawing wire, and the unlocking piece is rotationally linked with the limiting block and the driving block. Compared with the prior art, no matter the locking motor is damaged when the door lock is in any state, the electric lock can be unlocked manually; and the same door lock can use the locking motor with low power, and is reasonable in structural design, safe, reliable, low in energy consumption and low in cost.

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.
