The specific embodiment

See also Fig. 1 and find out by knowing among the figure that to shown in Figure 4 drive unit of the present utility model includes transmission group 1, winder 2 and pedestal 3, wherein:

This transmission group 1 is provided with driver 11 and drive screw 12, and driver 11 has motor 111 and motor screw rod 112, and motor screw rod 112 is for having three age of a draught animal screw rods of triple thread; This drive screw 12 is provided with driven gear 121, and driven gear 121 both sides are respectively arranged with travelling gear 122 and transmission worm screw 123.

This winder 2 is provided with axostylus axostyle 21, and axostylus axostyle 21 1 sides are connected with passive fluted disc 211, and axostylus axostyle 21 is articulated with connecting rod 23 near the end of passive fluted disc 211, and winder 2 is provided with interlock fluted disc 22 in connecting rod 23 1 sides, and interlock fluted disc 22 surfaces convex with reference column 221, and make connecting rod 23 be articulated in reference column 221 away from articulating axostylus axostyle 21 other ends, and axostylus axostyle 21 is provided with line wheels 24 away from the opposite side of passive fluted disc 211, and line wheels 24 are provided with first line wheel, 241 and second line wheel 242 side by side, and in first line wheel, 241 and second line wheel 242, be respectively arranged with the unilateral bearing 25 that is sheathed on axostylus axostyle 21 outer rims, and but two unilateral bearings, 25 pivotal orientation are opposite each other, and take turns 242 surfaces in first line wheel, 241 and second line and be respectively equipped with first helicitic texture 2411 and second helicitic texture 2421.

This pedestal 3 is provided with body 31, and body 31 both sides are respectively arranged with first lid 32 and second lid 33, make first lid 32 be formed with first accommodation space 34 with body 31, and second lid 33 is formed with second accommodation space 35 with body 31.

Thus, when the utility model in group during structure, be that transmission group 1 is placed in first accommodation space 34, make drive screw 12 be articulated in first accommodation space, 34 both sides, and driver 11 is fixedly arranged on the below, make driver 11 set motor screw rods 112 be engaged in the set driven gear 121 of drive screw 12, it is the side that drive screw 12 laterally is articulated in motor screw rod 112, continue this winder 2 is placed in first accommodation space 34, and axostylus axostyle 21 is extended in second accommodation space 35 by first accommodation space 34, and allow line wheels 24 be positioned at second accommodation space 35, and the set interlock fluted disc 22 of winder 2 and passive fluted disc 211 are for being engaged in transmission worm screw 123 and travelling gear 122 respectively.

Please consult Fig. 2 simultaneously to shown in Figure 6, find out by knowing among the figure, the utility model is wound in first line wheel, 241 and second line respectively with the both sides of the stay cord 4 of curtain and takes turns 242 surfaces when using, because first line wheel, 241 and second line wheel 242 is respectively equipped with first helicitic texture 2411 and second helicitic texture 2421, make the coiling that stay cord 4 can be neat, and when the motor 111 of driver 11 drives 112 rotations of motor screw rod, motor screw rod 112 pivots drive screw 12 for driving driven gear 121, making drive screw 12 rely on travelling gear 122 and transmission worm screw 123 to drive passive fluted disc 211 pivots and interlock fluted disc 22 pivots, allow axostylus axostyle 21 rotate, this moment is because first line wheel 241 is opposite each other with second line wheel, 242 unilateral bearings 25 that are connected with axostylus axostyle 21, make axostylus axostyle 21 when turn, wherein a unilateral bearing 25 is free pivot state (identical with axostylus axostyle 21 pivotal orientation), another unilateral bearing 25 is by axostylus axostyle 21 driven rotary (opposite with axostylus axostyle 21 pivotal orientation), therefore, first line wheel, 241 and second line wheel 242 can present respectively and driven pivots by axostylus axostyle 21 and furl stay cord 4, and deviate to rotate because of stay cord 4, so that taking turns 242, first line wheel, 241 and second line furl or make stay cord 4 to deviate from respectively.

Moreover, because transmission worm screw 123 also can be when axostylus axostyle 21 rotates, driving interlock fluted disc 22 simultaneously pivots, its reference column 221 drivening rods 23 are moved along the rotation of the rotate path of interlock fluted disc 22, make laterally displacement repeatedly of axostylus axostyle 21, and then drive laterally displacement back and forth of line wheels 24 simultaneously, when first line wheel, 241 and second line wheel 242 being rolled up put stay cord 4, allow neat the furling in first line wheel, 241 or second line and take turns 242 side by side of stay cord 4.

See also shown in Figure 3ly again, find out by knowing among the figure, motor screw rod 112 of the present utility model makes motor 111 when outage for having three age of a draught animal screw rods of triple thread, and drive screw 12 also can pivot, and produces the problem of self-locking because of outage to prevent motor 111.

Be with, the utility model for solving the deficiency and the disappearance of known technology, its key technology is:

(1) the utility model utilizes line wheels 24 in rolling up when putting stay cord 4, utilize axostylus axostyle 21 to drive the 24 laterally displacements back and forth of line wheels simultaneously, stay cord 4 can neatly be furled be arranged in first line wheel, 241 or second line wheel 242, produce when preventing that stay cord 4 from furling abnormal staggeredly, and can't emit.

When (two) the utility model utilizes unilateral bearing 25 to make first line wheel, 241 and second line wheel 242 driven by axostylus axostyle 21, first line wheel, 241 and second line wheel 242 can present respectively and driven pivots by axostylus axostyle 21 and furl stay cord 4, and deviate to rotate because of stay cord 4, get loose with of the diameter different generations of second line wheel 242 to prevent first line wheel 241 because of stay cord 4 coilings.

(3) the utility model driver 11 set motor screw rods 112 are three age of a draught animal screw rods with triple thread, make motor 111 when outage, and the user also can control curtain by pulling stay cord 4, produce the problem of self-locking because of outage to prevent motor 111.

The above person only, it only is preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this, so the change of numerical value or displacement of equivalent elements such as, or, all should still belong to the category that the utility model patent contains according to equalization variation and modification that the utility model claim is done.
