Embodiment
In order more clearly to explain the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1-2, the electrically driven curtain free wheel device that the utility model provides, comprises fixed base 10, iron plate 11, roller 12, active rotation axle 13 and driven clutch ring 14, a plurality of bearings 15 are installed in fixed base 10, the bottom of active rotation axle 13 is run through iron plate 11 and a plurality of bearing 15 successively, the top movable of active rotation axle 13 is set in driven clutch ring 14, the top of active rotation axle 13 is provided with flat position 131, roller 12 is installed on flat position 131, and the bottom of roller 12 is provided with the magnetic layer (not shown) with iron plate 11 suitable adhesives, by magnetospheric effect, iron plate 11 can be pull-in on roller 12, when being provided with active rotation axle 13 and rotating, the inwall of driven clutch ring 14 stops while rotating for limiting the ellipse arc face 142 of roller 12 motions for holding the arc groove 141 of roller 12 and active rotation axle 13.By the effect of arc groove 141, realize the common rotation of driven clutch ring 14 and active rotation axle 13, by the effect of ellipse arc face 142, realize driven clutch ring 14 separated with surmounting of active rotation axle 13.
Compared to the situation of prior art, the electrically driven curtain free wheel device that the utility model provides, when active rotation axle 13 rotates, roller 12 is fallen in arc groove 141, and driven clutch ring 14 is just along with rotating together; When active rotation axle 13 stops operating, roller 12 is limited in the interior motion of ellipse arc face 142, can not fall in arc groove 141 again; The improvement of this structure, make driven clutch ring 14 no matter toward which direction rotation, roller 12 can not fall in the arc groove 141 of driven clutch ring 14 and go, and just can not follow driven clutch ring 14 rotations as the active rotation axle 13 of driving link, thereby make the separated of active rotation axle 13 and driven clutch ring 14, so just realized the unidirectional transmission agency of free wheel device.The utlity model has simple and practical, convenient, low cost of manufacture is installed, the advantage such as transmission noise is low, driving torque large, long service life, not only solved that the transmission of traditional electrical magnet clutch is existing problems such as driving torque is little, easy wear out failure; And adopt Purely mechanical transmission, and can greatly reduce the power loss in motor operation course, allow electrically driven curtain become more low power consumption, operation safety and reliability.
In the present embodiment, the outlet port, top of fixed base 10 is provided with a groove 101, and iron plate 11 is fixed in this groove 101 and encloses for holding the cavity of a plurality of bearings 15 with fixed base 10.This structure is that iron plate 11 and a plurality of bearing 15 are installed in fixed base 10, has rationally utilized space.Certainly; the utility model is not limited to shape and the structure of fixed base 10; as long as can guarantee that iron plate 11 is connected the mode of execution of the rear work realizing with active rotation axle 13 with a plurality of bearings 15; all belong to simple deformation of the present utility model or conversion, fall into protection domain of the present utility model.
In the present embodiment, the outer wall of driven clutch ring 14 is provided with for adjusting the breach 143 of roller 12 positions, after using, during roller 12 position change, can carry out small adjustment by the position of 143 pairs of rollers 12 of breach if long-time.Certainly; the utility model is not limited to above-mentioned mode of execution, if exchange the change of perfect square formula, as long as can realize the mode of execution of these roller 12 small adjustment in position; all belong to simple deformation of the present utility model or conversion, fall in protection domain of the present utility model.
In the present embodiment, magnetic layer be installed in roller 12 bottom magnetic sheet or be coated in the magnetic coating of the bottom of roller 12.Certainly, magnetic layer is not limited to magnetic sheet or magnetic coating, can also be magnetic patch etc.; so long as it is all passable to have the material of magnetic action; if the change of magnetic layer kind all belongs to simple deformation of the present utility model or conversion, fall in protection domain of the present utility model.
Please further consult Fig. 3, the electrically driven curtain free wheel device that the utility model provides, its working principle is as follows: if when active rotation axle 13 clockwise rotates, the flat position 131 of active rotation axle 13 can drive roller 12 to rotate together, when roller 12 rotates to the A point of driven clutch 14, roller 12 can fall in the arc groove 141 of driven clutch ring 14, and driven clutch ring 14 just can be followed together and rotate.By the time, after active rotation axle 13 stops, under electronic control, active rotation axle 13 meeting opposite spin 120-150 degree, make roller 12 detach arc groove 141.Because be one section of elliptic arc transition from A point to B point in driven clutch ring 14, be the ellipse arc face 142 shown in Fig. 1, with in this process of reversion, roller 12 can lean on toward center gradually, when roller 12 is after C point, just can not lean on inward again, now as the driven clutch ring 14 of driven member, no matter toward which direction rotation, roller 12 can not fall in the arc groove 141 of driven clutch ring 14 and go, and just can not follow driven clutch ring 14 rotations as the active rotation axle 13 of driving link, thereby make the separated of active rotation axle 13 and driven clutch ring 14, so just realized the unidirectional transmission agency of free wheel device.In like manner, to rotate counterclockwise principle be the same to active rotation axle 13.
Disclosed is above only several specific embodiment of the present utility model, but the utility model is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
