The specific embodiment

Introduce a kind of specific embodiment of the present invention through Fig. 1 to 9 below.

Embodiment 1

Shown in Fig. 1 and 9, the tail-gate actuator of a kind of automobile-used automatically controlled integrated band automatic resetting mechanism of the present invention comprises motor 1, worm screw 2, worm gear 3, fork 4, housing base 5 and turbine wheel shaft 6; Said motor 1 drives said worm screw 2 and rotates; Said worm screw 2 drives said worm gear 3 and rotates around said turbine wheel shaft 6; The center of circle of said worm gear 3 upper edge worm gears 3 is symmetrical set two protruding posts 31, and said fork 4 is forks of automatic spinning reduction, and said fork 4 is provided with a swing arm 41 and a lock-bit 42; Said protruding post 31 is stirred the swing arm 41 of said fork 4; Said fork 4 rotates around the axle that self cooperates with said housing base 5, and said protruding post 31 is with the rotation of said worm gear 3, and circulation changes or produce said lock-bit 42 over to.The axle center that said fork 4 cooperates with said housing base 5 is provided with a key piece slot 7.Swing arm 41 bendings on the said fork 4 are turned back and are formed said lock-bit 42.

Wherein, said lock-bit 42 is to the spacing on the plane of said worm gear 3 height greater than said worm gear 3 raising posts 31; The end of said swing arm 41 is provided with a protruding block 43 to the direction of said worm gear 3, and said protruding post 31 is stirred said protruding block 43 and driven said fork 4 rotations.After protruding post 31 backs down protruding block 43, slip into lock-bit 42, fork 4 no longer receives stopping of worm gear 3, and fork 4 is self-return under the effect of ratchet restoring force F.
