Automobile electric tail door lock
The invention discloses an automobile electric tail door lock, and belongs to the field of automobile tail door locks. The automobile electric tail door lock structurally mainly comprises a gear reduction transmission chain component, a lock body component, a bottom plate, an outer cover and the like, wherein the gear transmission chain component comprises a one-stage worm gear, a two-stage planetary gear and a two-stage gear reduction component; the lock body component mainly comprises a second sector gear, a third sector gear with a lock hook and a jacking claw; during unlocking, after the output torque of a motor is subjected to five-stage speed reduction, a shifting rod extending out of a first sector gear is driven to to shift the jacking claw, so that the jacking claw is separated from the lock hook, an opening of the lock hook is downward under the action of a torsion spring, and a lock body is opened; and when a tail door is closed, a lock rod on an automobile trunk collides with the lock hook of the third sector gear to enable the third sector gear to rotate anticlockwise, the jacking claw abuts against the lock hook under the action of the torsion spring, the tail door lock enters a semi-locking state, then the motor is started to drive the first sector gear to rotate clockwise, after a boss on the first sector gear is tightly attached to the side face of the second sector gear, the motor is stopped, and reliable locking is realized.
本发明公开了一种汽车电动尾门锁，属于汽车尾门锁领域，其结构主要包括齿轮减速传动链部件、锁体部件、底板和外罩等，其中齿轮传动链部件包括一级蜗轮蜗杆、两级行星齿轮和两级齿轮减速部件；锁体部件主要包括第二扇形齿轮、带有锁钩的第三扇形齿轮和顶爪；当开锁时，电机输出扭矩经五级减速后驱动第一扇形齿轮上伸出的拨杆拨动顶爪，使其脱离锁钩，锁钩在扭转弹簧的作用下开口向下，打开锁体；当关闭尾门时，汽车尾箱上的锁杆撞击第三扇形齿轮的锁钩，使其逆时针转动，顶爪在扭转弹簧作用下顶住锁钩，尾门锁进入半锁状态，随后，启动电机驱动第一扇形齿轮顺时针转动，使其上的凸台贴紧第二扇形齿轮侧面后停止电机，实现可靠锁紧。
