As further illustrating of such scheme, the outside of described drive motors gear is connected with clutch, drive motors gear consists of gear mass and the toothed disc that is connected in gear mass end face, on the side of toothed disc, is provided with cannelure, and a transmission jump ring is movably arranged on cannelure.
Described clutch comprises the clutch motion bar that is socketed with spring of clutch housing and interior setting thereof, the middle part of clutch housing is provided with and holds the through hole that machine shaft passes, in clutch housing, be provided with the hole slot that clutch motion bar and spring are installed respectively, the middle part of hole slot is provided with dividing plate, the end top of motion bar and spring is pressed on dividing plate, and the side of clutch housing is provided with the through hole being communicated with hole slot.
Described transmission worm screw and travelling gear are integral forming structure, and transmission worm screw is vertically set on the end face middle part of travelling gear, and the other end of travelling gear is provided with rotating shaft.
Described transmission worm screw and travelling gear are combination mounting structure, the inner side end middle part of travelling gear is provided with circular groove, the edge of circular groove is provided with the fixture block of two spaces, the end of transmission worm screw is provided with by two symmetrically arranged fan-shaped fixture blocks, the bottom of screw rod two secter pats that are connected, two secter pats are arranged between two fixture blocks of circular groove.
The middle part hollow out of described slide bar is chute, and the thread segment matching with transmission worm screw is arranged on the end of chute.
The internal side wall of described housing is provided with the chute sliding-contact at locating piece and described slide bar middle part, and one end of this locating piece arranges the recess matching with worm screw.
Described housing comprises upper cover and bottom, is provided with the caulking groove that drive motors, travelling gear and slide bar are installed respectively in bottom.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
1, the drive motors that the present invention adopts by automobile central controller drive and control, by drive motors, rotate and through transmission device, power passed to lock catch of door lock, lock catch of door lock is opened or locking, compared with prior art, its use control more convenient.
2, the present invention by clutch motion bar stretching out and contraction under centrifugal action, realize the clutch between clutch main body and travelling gear, therefore there will not be stuck phenomenon or hypodynamic problem occur to transmit.
