Special small self-priming lock for mini car tail door

Abstract

The invention discloses a special small self-priming lock for a mini car tail door, which is specially mounted on a car frame of the mini car tail door. According to the self-priming lock, a steel wire rope for locking the car door passes through a gap 23 between a sliding block 3 and a coupling piece 5 and then passes through a reset spring 4, and the head of the steel wire rope is clamped on a steel wire rope head buckling opening 331. In the using process, after the car tail door is tightly put on a car body, a buckling hook on the tail door is automatically hooked on a lock hook 12; after a door sensor of a mini car feeds back information, a mini car controller controls a motor to pull the steel wire rope, and the steel wire rope is tightened at the same time; the steel wire rope tenses the sliding block 3 to one end, and a lock catch 1 is tensed synchronously; after being tensed, the lock catch 1 firmly tenses the tail door, and therefore the tail door is closed. When the tail door needs to be opened, the motor is controlled through a switch to loosen, so that the steel wire rope gets loose, the sliding block 3 is returned back to the other end through the reset spring 4, the tail door hook is loosened, and at the moment the tail door can be opened.
