Fixed on the housing 10 , at this time, the relative positions of the hook 20 and the housing 10 are fixed, that is, the hook 20 and the housing 10 remain relatively stationary.

On the basis of the above structure, when using the curtain electric control driving device, the driving wheel 60 is attached to the bottom surface 91 of the external guide rail, and the adjusting screw 30 is rotated according to the actual situation. At this time, the adjusting screw 30 and the linkage mechanism 40 realize the force Then, the linkage mechanism 40 links the hook 20 up or down to adjust the position of the hook 20 relative to the housing 10. In the state shown in FIGS. 2 to 3, the linkage mechanism 40 links the hook 20 to lower relative to the housing 10. In this way, the hook 20 can be adjusted to an appropriate position, so that the hook 20 can just hang on the outer hanging ring 92 and keep the tension state. , using the hook 20 to replace the hanging wheel, eliminating the size requirements for the hanging groove of the curtain rail 90, and the position of the hook 20 can be adjusted according to the curtain rail 90 of different sizes, and the applicability is strong; after that, the driving mechanism 70 drives the driving wheel 60 rotates, at this time, under the action of friction between the driving wheel 60 and the external guide rail, the driving wheel 60 moves along the external guide rail 90, and drives the external hanging ring 92 hooked with the hook 20 to move, and when the external hanging ring 92 moves, the curtain is pushed The other external hanging loops 92 on the guide rail 90 move, thereby realizing the opening and closing of the electronically driven curtain.

Specifically, the above-mentioned linkage mechanism 40 can adopt the following two implementations. In the first embodiment, the above-mentioned linkage mechanism 40 includes a first linkage block 43; In this way, when the adjusting screw 30 is rotated, at this time, due to the threaded cooperation of the first linkage block 43 and the adjusting screw 30, the first slider drives the hook 20 to rise and fall relative to the adjusting screw 30, that is, the adjusting screw 30 is realized through the first linkage. The block 43 moves up and down in conjunction with the hook 20 .

Embodiment 2. The linkage mechanism 40 includes a second linkage block 41 and an elastic element 42; the second linkage block 41 is installed on the casing 10 and can be lifted and lowered relative to the casing 10; the second linkage block 41 is screwed with the adjusting screw 30 , and push down against the hook 20; the two ends of the elastic element 42 are respectively against the hook 20 and the housing 10; the elastic element 42 is used to provide the elastic stress that promotes the upward movement of the hook 20 and collides with the second linkage block 41; During use, when the hook 20 needs to be raised, the adjusting screw 30 is rotated to make the second linkage block 41 move upward relative to the housing 10. At this time, under the push of the elastic element 42, the hook 20 is pushed upward. In this way, the realization of The hook 20 rises; and when the hook 20 needs to be lowered, the adjusting screw 30 is rotated to move the second linkage block 41 downward relative to the housing 10. At this time, the second linkage block 41 pushes the hook 20 to compress the elastic element 42 to achieve The lowering of the hook 20; this arrangement facilitates the replacement of various components.

More specifically, the above-mentioned elastic element 42 is a spring, and the spring is sleeved outside the adjusting screw 30, and no other components are required to realize the installation of the spring, which simplifies the structure; The spring is over-bent and broken; the above-mentioned spring can also be an elastic sheet, an elastic column, and the like.

When the hook 20 and the outer hanging ring 92 are excessively tightened, the overall housing 10 tends to tilt away from the outer guide rail 90. Please refer to FIG. 5, that is, tilt along the left and right directions in FIG. 5. Ground, the bottom surface 91 of the outer guide rail is provided with a slot with the notch downward; the slot extends along the extension direction of the outer guide rail 90; the housing 10 is also fixed with a positioning post, and a positioning sleeve is detachably sleeved outside the positioning post. 50; The positioning sleeve 50 is used for matching and movably inserted into the slot of the outer guide rail 90; in this way, the positioning sleeve 50 is inserted into the slot to prevent the housing 10 from tilting outward, and the slot is along the outer guide rail 90. The extension direction extends to avoid the movement of the housing 10 being hindered by the positioning sleeve 50 when the housing 10 moves along the outer guide rail 90 .

The above-mentioned positioning sleeves 50 are detachable. In this way, for the external guide rails 90 of different sizes, the positioning sleeves 50 of different thicknesses can be replaced according to the width of the slot, or a plurality of positioning sleeves 50 can be selected to set the positioning sleeves 50. The total thickness exactly matches the slot width.

The above-mentioned driving mechanism 70 can adopt the existing rotary motor 74, rotary liquid cylinder, etc.; when the rotary motor 74 is used, the body of the rotary motor 74 is fixed on the housing 10, and the output shaft of the rotary motor 74 is connected to the drive wheel 60 in a transmission manner. .

In order to realize the free switching between electric and manual operation, preferably, a groove with a circular longitudinal section is provided on the side of the driving wheel 60; the central axis of the groove coincides with the central axis of the driving wheel 60; the groove wall of the groove is far away from A limit slot 61 is formed in the direction of its center; the driving mechanism 70 includes an adsorption plate 71, a transmission block 72, a push rod 73 and a rotary motor 74; the adsorption plate 71 is installed on the housing 10; the transmission block 72 is connected to the The adsorption plate 71 is magnetically adsorbed and located in the groove; in this way, the transmission block 72 is installed on the adsorption plate 71 and can move in any direction relative to the adsorption plate 71 under the action of external force; the body of the rotating motor 74 is installed in the casing 10; the output shaft of the rotating motor 74 is fixedly connected with the push rod 73; the push rod 73 is used to push the transmission block 72 when rotating, so that the transmission block 72 moves in the direction close to the groove wall to move the The transmission block 72 is pushed into the limit groove 61; the limit groove 61 is set so that when the push rod 73 does not push the transmission block 72 and the drive wheel 60 rotates under the action of an external force, the transmission block 72 can be separated from the limit groove 61; Specifically, the groove depth of the limiting groove 61 is smaller than the radius of the transmission block 72 , and the groove wall of the limiting groove 61 is arc-shaped.

On the basis of the above structure, when electric drive is required, the output shaft of the rotary motor 74 drives the push rod 73 to move in the direction A shown by the arrow in FIG. 7 (or in the opposite direction to the direction A shown by the arrow) Rotating, the push rod 73 rotates to the position where it pushes against the transmission block 72, and continues to push the transmission block 72 under the driving of the rotating motor 74. At this time, the thrust of the push rod 73 makes the transmission block 72 overcome the adsorption force of the adsorption plate 71, and at the same time 7, after overcoming the adsorption force of the adsorption plate 71, it can be seen from the force analysis that the transmission block 72 is also subjected to the thrust F as shown in FIG. Move in the direction close to the groove wall, and then the transmission block 72 enters the limit groove 61; the push rod 73 continues to push the transmission block 72, and squeezes the transmission block 72 to press the transmission block 72 into the limit groove 61, so that The transmission block 72 is stably located in the limit groove 61, and then the transmission block 72 continues to move with the push rod 73. When the transmission block 72 moves, it pushes the groove wall of the limit groove 61 to drive the driving wheel 60 to rotate, and then the driving wheel 60 is realized. When manual driving is required, the curtain is pulled, and the curtain drives the housing 10 to move and then the driving wheel 60 rotates in the direction shown by the arrow A in FIG. The thrust force will not be compressed in the limit slot 61, and then as the driving wheel 60 continues to rotate, the groove wall of the limit slot 61 pushes the transmission block 72, and the transmission block 72 is subjected to the adsorption force of the adsorption plate 71. Therefore, with the movement of the driving wheel 60, the transmission block 72 moves toward the notch and along the arc-shaped groove wall of the limit groove 61, and because the groove depth of the limit groove 61 is smaller than that of the transmission The radius of the block 72, at this time, the transmission block 72 can be separated from the limit groove 61 under the push of the limit groove 61. Therefore, since the transmission block 72 is separated from the limit groove 61, the driving wheel 60 is no longer caused by the rotation process. The blocking effect of the push rod 73 on the transmission block 72 hinders the rotation of the driving wheel 60 , thereby enabling manual operation.

Specifically, the adsorption plate 71 is an iron piece, and the transmission block 72 is a magnet; or, the adsorption plate 71 is a magnet, and the transmission block 72 is an iron block.

In order to realize the friction of the outer guide rail 90 of the driving wheel 60, preferably, the driving wheel 60 includes a driving wheel body 62 pivotally connected to the casing, and a non-slip sleeve 63 fixedly sleeved outside the driving wheel body 62. To ensure friction; the anti-skid cover 63 can be a rubber cover or a rubber cover with anti-skid transverse on the surface.

Specifically, a driven wheel 80 is also pivotally connected to the housing 10; the driven wheel 80 is pivotally connected to the housing 10 and protrudes from the top surface of the housing 10; the driven wheel 80 is also used for friction with the bottom surface 91 of the external guide rail In contact with the driving wheel 60, they are located on opposite sides of the housing 10, so as to achieve a more stable movement.

The above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of the present invention. Scope of protection claimed.
