Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, so that those skilled in the art can better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, the transmission device of electrically driven curtain of the present utility model, comprises motor 1, and the output shaft of motor 1 is connected with one end of a drive link 3.Preferably, the output shaft of motor 1 is connected with one end of drive link 3 by retarder 2.The other end of drive link 3 is provided with the first clutch wheel 8, the first clutch wheel 8 and coordinates rotation with drive link 3 and can on drive link 3, slide axially; The first clutch wheel 8 one sides cooperations are provided with when the second clutch wheel 10, the first clutch wheel 8 slide axially and can contact or separate with the second clutch wheel 10; Drive link 3 outsides are arranged with and promote resistance discs 5 and pushing disk 7, promote to be inclined-plane between resistance discs 5 and pushing disk 7 and coordinate; Drive link 3 is driven and is promoted resistance discs 5 and rotate by shifting part 4, and can make to promote resistance discs 5 and relatively rotate with drive link 3; Pushing disk 7 is provided with the limiting component that pushing disk 7 can only be in axial sliding.
In the time of work, the rotation of motor 1 output shaft passes to drive link 3, drives drive link 3 to rotate, and drive link 3 drives promotion resistance discs 5 to do corresponding rotation by shifting part 4, also drives the first clutch wheel 8 of drive link 3 ends to rotate simultaneously.Coordinate owing to promoting to be inclined-plane between resistance discs 5 and pushing disk 7, and due to the limited product restriction of pushing disk 7, can only be in axial sliding and can not rotate, therefore in the time that promotion resistance discs 5 rotates, promote resistance discs 5, by ramp effect, pushing disk 7 is formed to axial thrust, to promote the rotation of resistance discs 5 and be converted into the axial linear movement of pushing disk 7, between inclined-plane because mutually sliding and form rhombus space.Meanwhile, pushing disk 7 promotes the first clutch wheel 8 and also makes axial linear movement, until the first clutch wheel 8 contacts and produce certain pressure with the second clutch wheel 10.Now, the first clutch wheel 8 no longer can move axially, and pushing disk 7 also just no longer can move axially, and pushing disk 7 has stoped the rotation that promotes resistance discs 5 simultaneously.But because allowing to promote resistance discs 5, shifting part relatively rotates with drive link 3, therefore drive link 3 can be rotated further, and drive the second clutch wheel 10 to rotate by the first clutch wheel 8, and then by other transmission part, rotation is passed to curtain to reach the object of folding curtain.The method that rotation is passed to curtain by the second clutch wheel 10 belongs to prior art, does not repeat them here.
When curtain open/close to need position time, controlling motor 1 stops operating and carries out of short duration reversion, drive link drives promotion resistance discs 5 to reverse by shifting part, this reverse action makes to promote the inclined-plane revolution at resistance discs 5 rears, this revolution makes to promote resistance discs 5 end thrust of pushing disk 7 is disappeared, pressure between the first clutch wheel 8 and the second clutch wheel 10 also disappears, and the first clutch wheel 8 and the second clutch wheel 10 are thrown off.If now there is the manual folding curtain of people, the motion of curtain is delivered to the second clutch wheel 10 and stops, and can not be delivered to motor 1, thereby reaches the object of protection motor.
In the present embodiment, one end that drive link 3 coordinates with the first clutch wheel 8 is prism-shaped, and the first clutch wheel is provided with rib groove 801, and the prism-shaped end 301 of drive link 3 is inserted in rib groove 801.So, can realize the first clutch wheel 8 can rotate and moving linearly in the axial direction with drive link 3.In other embodiments, also the position of prism and rib groove can be exchanged, be arranged to prism in the end of the first clutch wheel, and in drive link one end, rib groove is set.Preferably, as shown in Figure 1, prism is square column, and corresponding rib groove is square groove.Certainly, between the first clutch wheel and drive link, also can adopt the structure of cylinder and the mutual fit of cylinder, only need on both fitting surfaces, arrange and stop the structure of rotating, for example on parts, fin is set and chute is set on another parts, or chute is all set on two parts and in chute, inserts a key etc.
Embodiment shown in Figure 1, shifting part is preferably interference spring 4, and interference spring 4 interference fit are in the outside of the column part of drive link 3, and the 4 outside bendings in one end of interference spring form protuberance 401, and protuberance 401 stretches in the draw-in groove promoting in resistance discs 5.When the resistance being subject in promotion resistance discs 5 is less than the frictional force between interference spring 4 and drive link 3, interference spring 4 rotates together with drive link 3, and stirs promotion resistance discs 5 and rotate.In the time promoting the resistance that is subject to of resistance discs 5 and be less than the frictional force between interference spring 4 and drive link 3 (being generally to contact generation afterwards with the second clutch wheel 10 in the first clutch wheel 8), interference spring 4 no longer rotates, and drive link 3 can be rotated further.Certainly, shifting part can also adopt other structure, for example, groove is set on drive link, and pin is set on shifting part, and pin supports in the groove on drive link under the effect of elastic component, and coordinates with pin and groove are curved.So, when promoting the resistance that is subject to of resistance discs hour, drive link is driven shifting part and is promoted resistance discs by pin and rotates, and when the resistance that is subject to when promotion resistance discs is larger, pin is extruded from groove, and shifting part can be relatively rotated with drive link.
In the embodiment shown in fig. 1, limiting component is a sleeve 6, sleeve 6 is sheathed on pushing disk 7 outsides and after installation, is fixed in the shell of transmission device of electrically driven curtain, between sleeve 6 and pushing disk 7, form the chute 601 and fin 701 structures that cooperatively interact, thereby pushing disk 7 can be slid axially and not rotatable.In addition, limiting component can be also slide rail, and slide rail is arranged in the through hole on pushing disk 7, can make equally pushing disk 7 slide axially and not rotatable.
The ramp structure promoting between resistance discs 5 and pushing disk 7 is preferably the flexuose compound mitre structure shown in Fig. 1, so both simple in structure, can realize again motor and rotate towards both direction respectively time, can make the first clutch wheel 8 contact with the second clutch wheel 10, thereby realize opening and closing of curtain.
Further preferably, between the first clutch wheel 8 and the surface of contact of the second clutch wheel 10, be formed with concaveconvex structure, to increase the frictional force between the first clutch wheel 8 and the second clutch wheel 10, prevent from skidding.In addition, can also between the first clutch wheel 8 and the second clutch wheel 10, spring 9 be set, with in the time that motor turns round, utilize the elastic reaction of spring 9 that the first clutch wheel 8 is pushed away to the second clutch wheel 10, ensure both separation, improve reliability.
As shown in Figure 1, can also gear disk 11 be set at the opposite side of the second clutch wheel 10, by gear disk 11, the rotation of the second clutch wheel 10 be passed.
In addition, the electrode of motor 1 is connected with controller, and controller is for controlling the start and stop of motor, and of short duration reversion after at every turn stopping, and reversing time can be controlled by the timer that is connected to controller.In order to realize the protection to motor; for example curtain open/close to the end or in moving process, run into resistance and can not move, is also connected with protective circuit on controller, and protective circuit is for detection of the electric current that flows through motor; in the time that electric current reaches a threshold value, control motor and stop and the distance of reversing.
Particularly, as shown in Figure 2, controller is connected to motor, is also connected with testing circuit on motor, and testing circuit is connected with a comparator circuit, and comparator circuit is connected with time circuit and controller.Wherein testing circuit and comparator circuit have formed protective circuit jointly.Testing circuit is for detection of the electric current that flows through motor; and current value is outputed to comparator circuit; comparator circuit compares the current value of testing circuit output and a default current value; if the current value of testing circuit output is greater than default current value; export a protective signal (for example high level signal or low level signal) to time circuit and controller; timing when time circuit leaves, and controller control motor stops and reversing.When time circuit timing to set time after, motor reversal one distance, send stop signal to controller, controller control motor stalling.The distance of motor reversal is so that the first clutch wheel 8 can be thrown off the second clutch wheel 10 is as the criterion.
Protective circuit based on principle time, in the time that curtain open/close is obstructed, resistance is delivered to motor through transmission part, motor can not rotate, the electric current that flows through motor can raise, the electric current of this rising may burn out motor.Therefore, in the time the electric current that flows through motor being detected higher than normal operating current, can think and need starting protection, stop motor.In general, in order to prevent spread of voltage or the inhomogeneous current fluctuation false triggering protection causing of resistance everywhere, default current value should be slightly larger than normal operating current.
The above embodiment is only the preferred embodiment for absolutely proving that the utility model is lifted, and protection domain of the present utility model is not limited to this.What those skilled in the art did on the utility model basis is equal to alternative or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
