the specific embodiment

Below by Fig. 1 to 9, introduce a kind of specific embodiment of the present invention.

Embodiment 1

As shown in Fig. 1 and 9, the control integrated tail-gate actuator with automatic resetting mechanism of a kind of vehicle electric of the present invention, comprises motor 1, worm screw 2, worm gear 3, fork 4, housing base 5 and worm-wheel shaft 6; Described motor 1 drives described worm screw 2 to rotate, described worm screw 2 drives described worm gear 3 to rotate around described worm-wheel shaft 6, the center of circle along worm gear 3 on described worm gear 3 is symmetrical arranged two protruding posts 31, described fork 4 is forks that automatic rotation resets, described fork 4 is provided with a swing arm 41 and a lock-bit 42, described protruding post 31 is stirred the swing arm 41 of described fork 4, the axle that described fork 4 coordinates with described housing base 5 around self rotates, described protruding post 31 is with the rotation of described worm gear 3, and circulation proceeds to or produce described lock-bit 42.Described fork 4 coordinates Zhou center to be provided with a key piece slot 7 with described housing base 5.Swing arm 41 bendings on described fork 4 are turned back and are formed described lock-bit 42.

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