Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is the utility model structural representation;
Fig. 2 is miniature either-rotation motor, governor gear, swiveling wheel, lock pin mounting structure schematic diagram;
Fig. 3 is swiveling wheel lateral view of the present utility model;
Fig. 4 is that swiveling wheel of the present utility model is in abutting connection with the structural representation of miniature either-rotation motor end.
The specific embodiment
As shown in Figures 1 to 4, be the specific embodiment of Electric lock drive unit of the present utility model, it comprises miniature either-rotation motor 100, governor gear 101, swiveling wheel 102, lock pin 103, miniature either-rotation motor 100, governor gear 101, swiveling wheel 102, lock pin 103 word orders are installed in the housing 10.The output shaft of miniature either-rotation motor 100 is connected with governor gear 101, and when connecting circuit, output shaft provides moment of torsion to governor gear 101, so that governor gear 101 rotations.Swiveling wheel 102 1 ends have pin-and-hole 112, pin-and-hole 112 is non-circular, can be deltiod, polygon or unfilled corner are circular, this pin-and-hole 112 is connected with the output shaft of governor gear 101 respective shapes, swiveling wheel 102 other ends have the helicoid A that extends around himself central axis, helicoid A peak is A1, minimum point is A2, the end of lock pin 103 is around himself axis relative set helicoid B corresponding with swiveling wheel helicoid A, helicoid A and helicoid B engagement, thus the rotation of miniature either-rotation motor 100 so that lock pin 103 can be between extended position and retracted position rectilinear motion.
The center of described lock pin 103 is provided with round center hole 109, and the center of described helicoid A is provided with the cylindric projection 108 that inserts in the described centre bore 109.Described governor gear 101 is located in the gear-box, and described gear-box is fixed in described miniature either-rotation motor 100 ends.
The core of the helicoid A of described swiveling wheel is provided with spiral groove, and the helicoid B core of described lock pin is provided with the convex bar of respective shapes.So that contacting of swiveling wheel 102 and lock pin 103 is closely corresponding, be not easy.
Described gear-box is square structure, miniature either-rotation motor 100 shell left and right sides walls are a plane 106, miniature either-rotation motor 100 tops and bottom left and right sides 107 are an arcwall face or inclined-plane, described housing is comprised of left side housing and right side housing, the corresponding described miniature either-rotation motor 100 of left side housing and right side inner walls upper and lower is provided with mounting bar 104, the installed surface of described mounting bar is arcwall face or inclined-plane, and the corresponding described gear-box of described left side housing and right side housing is provided with a mounting groove 105.When installing like this, miniature either-rotation motor 100 tops and bottom left and right sides 107 cooperate with the installed surface of mounting bar, and gear-box snaps in the described mounting groove 105.
When lock pin 103 arrived maximum position to the extended position motion, the top of helicoid A contacted with the top of helicoid B, can produce very large noise if arrange block piece this moment, and meeting brings many adverse effects so that motor stops operating suddenly.For the rotation of better control swiveling wheel 102 accurate, arrange at swiveling wheel 102 on the end face of pin-and-hole 112, leave pin-and-hole 112 at a certain distance, a boss 110 is set, corresponding position in housing 10 correspondences is provided with friction block piece 111, so that swiveling wheel is when rotating to certain position, when lock pin arrives at extended position, so that produce CONTACT WITH FRICTION between boss 110 and the friction block piece 111, slow down and stop at last the continuation rotation of swiveling wheel, and so that helicoid A and helicoid B can not disengage, can carry out smoothly the retraction operation of lock pin 103.As preferred embodiment, described boss 110 is circular arc, and described friction block piece 111 is strip, increases so that boss 110 and friction block piece 111 directly are in contact with one another gradually, and the rotation of swiveling wheel 102 is slowed down mild.
