Abstract

The invention discloses an electric door lock and a control method of the electric door lock. The electric door lock comprises a motor, a spring bolt and a controller. The installation end of the spring bolt is connected with an elastic mechanism. The motor is in transmission connection with the spring bolt so as to drive the spring bolt to move. The controller is connected with the motor. The controller can control the motor to operate at a first voltage after obtaining an unlocking instruction. After obtaining information for representing that the spring bolt is located at the recovery position, the controller can control the motor to operate at the second voltage lower than the first voltage. When the motor operates at the second voltage, the torque of an output shaft of the motor is small, so that thrust transmitted to the elastic mechanism is small, and therefore it is avoided that the spring bears squeezing of large thrust; and in this way, the elasticity of the spring and the safety of the electric door lock are guaranteed.

Description

technical field

[0001] The invention relates to the technical field of electric door locks, in particular to an electric door lock and a control method thereof. Background technique

[0002] With the development of science and technology, various electric door locks have gradually entered people's lives.

[0003] The electric door lock drives the deadbolt to move in a straight line through the motor to open and close the door lock. The installation end of the existing deadbolt is connected with the spring, when no external force acts on the deadbolt, the spring will push the installation end of the deadbolt to move to the other end of the deadbolt so that the deadbolt reaches the pop-up position from the recovery position, realizing Automatic locking of the door lock.

[0004] The inventor found through research that: when the electric door lock drives the deadbolt from the pop-up position to the recovery position through the motor, the motor still exerts a relatively larg...
