Abstract

A door lock assembly includes a door lock slider, a slider gear and a bias device. The door lock slider reciprocates in a first linear direction and a second linear direction along the length of the door lock slider. The door lock slider includes a slider body provided with a slider groove in a length direction of the door lock slider body. The slider groove is provided with a slider rack. The slider gear is mounted in the slider groove and rotates about a rotating shaft. The slider gear engages with the door lock slider rack. When the slider gear rotates clockwise or counterclockwise, the door lock slider reciprocates in the first linear direction or the second linear direction. The bias device is configured to drive the slider gear which drives the door lock slider in the second linear direction.
