Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises Electric Machine Control part 1, guide rail 2 and secondary part 23, wherein Electric Machine Control part 1 comprises Electric Machine Control partial shell 20, brushless electric machine and clutch, secondary part 23 comprises secondary part housing 21 and driven pulley 22, and the two ends of guide rail 2 are affixed Electric Machine Control partial shell 20 and secondary part housing 21 respectively.
Brushless electric machine in Electric Machine Control part 1 and clutch are all positioned at Electric Machine Control partial shell 20, as shown in Fig. 2, Fig. 3 and Fig. 8, clutch comprises driving pulley 3, disk spring 4, worm gear 5, flexible steel ring 6, ball 7, abrasionproof backing plate 8, copper sheathing 9 and worm screw 10, and this worm screw 10 is connected with the output of brushless electric machine, drives rotation by brushless electric machine; In the Electric Machine Control partial shell 20 at guide rail 2 two ends, left and right and secondary part housing 21, be separately installed with rotating driving pulley 3 and driven pulley 22, between driving pulley 3 and driven pulley 22, be connected by cog belt, cog belt is provided with the Curtain ring 19 of multiple extension curtain.On the wheel shaft of driving pulley 3, coaxial sleeve is provided with worm gear 5, flexible steel ring 6 and abrasionproof backing plate 8 successively, is respectively equipped with copper sheathing 9 at the two ends of these driving pulley 3 wheel shafts.Worm gear 5 is meshed with worm screw 10, flexible steel ring 6 and worm gear 5 interlocks, abrasionproof backing plate 8 is positioned at the below of this flexible steel ring 6, between flexible steel ring 6 and abrasionproof backing plate 8, be provided with ball 7, disk spring 4 is installed on worm gear 5, disk spring 4 compresses worm gear 5, and the elastic force of disk spring 4 is pressed on ball 7 worm gear 5, flexible steel ring 6, makes ball 7 and abrasionproof backing plate 8 remain pressure state.
As shown in Figure 4, Figure 5, flexible steel ring 6 is provided with two pins 11 and two bendings 12, and pin 11 is arranged alternately along the circumferencial direction of flexible steel ring 6 with bending 12, and bending 12 is two platy structures that are parallel to each other.Two pins 11 and two bendings 12 are respectively symmetrically, and the line between two pins 11 is coplanar and mutually vertical with the line between two bendings 12, the line between the line between two pins 11 and two bendings 12 respectively with driving pulley 3 axle axial vertical and intersectant centerlines.Ball 7 between flexible steel ring 6 and abrasionproof backing plate 8 is two, is symmetrical arranged with the longitudinal center line of driving pulley 3 wheel shafts, and line and driving pulley 3 axle axial vertical and intersectant centerlines between two balls 7.In the process that ball 7 rotates with worm gear 5 at flexible steel ring 6, by the along the circumferential direction reciprocating rolling between pin 11 and bending 12 that acts on abrasionproof backing plate 8 of frictional force.Follow in the process of ball 7 reciprocating rollings, flexible steel ring 6 produces elastic deformation, drives pin 11 to move up and down.
As shown in Figure 6, Figure 7, on worm gear 5, have the straight trough mouth 13 corresponding with pin 11 and bending 12, square groove 14, straight trough mouth 13, square groove 14 are respectively two, are along the circumferential direction alternately opened on worm gear 5, are symmetrical arranged respectively with the axial centre of driving pulley 3 wheel shafts; Line between two straight trough mouths 13 is coplanar and vertical with the line between two square grooves 14, and intersects vertically with the axial centre of driving pulley 3 wheel shafts respectively.Bending 12 on flexible steel ring 6 is connected in the square groove 14 of offering on worm gear 5, in the straight trough mouth 11 on the 11 insertion worm gears 5 of pin on flexible steel ring 6.On worm gear 5, be along the circumferential direction also evenly equipped with multiple arcuate sockets 15, the arcuate socket 15 of the present embodiment is four, and each arcuate socket 15 is all between straight trough mouth 13 and square groove 14; Four arcuate sockets 15 can alleviate the deadweight of worm gear 5, and the circle at four arcuate socket 15 places is concentric with the center of circle of worm gear 5.
On the wheel disc 18 of driving pulley 3, have two semicircular driving grooves 16, be symmetrical arranged with the longitudinal center line of driving pulley 3 wheel shafts; In the time that ball 7 is rolled into pin 11 below, pin 11 rises in driving groove 16, and with side 17 butts of driving groove 16.
Operation principle of the present utility model is:
Brushless electric machine drives worm screw 10 that worm gear 5 is rotated, and drives flexible steel ring 6 to rotate and (be connected with bending 12 by square groove 14, as shown in Figure 6) in the time that worm gear 5 clockwise rotates.Disk spring 4 compresses worm gear 5, and the elastic force of disk spring 4 is pressed on ball 7 worm gear 5, flexible steel ring 6, makes ball 7 and abrasionproof backing plate 8 remain pressure state (as shown in Figure 4).In the time that flexible steel ring 6 clockwise rotates with worm gear 5, ball 7 produces relatively and rolls between flexible steel ring 6 and abrasionproof backing plate 8; After ball 7 is rolled to pin 11 bottom margins and blocks (as shown in Figure 5), flexible steel ring 6 distortion are risen pin 11, see through in the driving groove 16 on the wheel disc 18 that the straight trough mouth 13 of worm gear 5 injects driving pulley 3, contact (as shown in Figure 7) with the side 17 of driving groove 16, drive driving wheel band 3 to clockwise rotate to reach connection function.Cog belt transmission between driving pulley 3 and driven pulley band 22, and then drive Curtain ring 19 to move, realize the folding of curtain.
In the time that needs clutch is thrown off, only need to allow worm gear 5 drive that flexible steel ring 6 is counter to be turn 90 degrees, can make pin 11 depart from driving groove 16, thereby reach the object that worm gear 5 and driving pulley 3 disconnect.
Brushless electric machine of the present utility model is controlled by control device (prior art), and this control device can, by remote controller control, be realized controlled in wireless electric folding.
