Description

Technical Field

[0001] The present invention relates to the technology of electric curtain control, and in particular to a bendable rail vertical curtain control device integrating the dual functions of flipping and opening / closing. Background Art

[0002] In traditional technology, most curtains are opened and closed manually. This traditional way of operating curtains is rather troublesome and the user comfort is poor.

[0003] In order to improve the user comfort of using curtains, currently, electric curtains that can be electrically operated to open and close have been introduced in the market. However, the existing electric curtains still have the following problems in specific use:

[0004] Existing electric curtains are generally used for installing cloth curtains and roller blinds. Although the structures of these electric curtains are simple, since cloth curtains and roller blinds have poor daylighting effects, more and more families and office environments choose to use accordion curtains and pleated curtains. However, most of the existing accordion curtains and pleated curtains are mainly installed horizontally. With the improvement of people's housing conditions, the requirements for indoor daylighting, ventilation, etc. are getting higher and higher. Therefore, the sizes of room windows are also getting larger and larger. The use of horizontally installed accordion curtains and pleated curtains has its limitations. Especially when the window position is an irregular convex shape, arched shape or has a corner, the existing electric curtains cannot support the opening and closing of curved rails and the flipping of curtain blades. Therefore, it is necessary to develop an electric control device suitable for vertical curtains. Summary of the Invention

[0005] In view of this, in view of the deficiencies of the existing technology, the main purpose of the present invention is to provide a bendable rail vertical curtain control device integrating the dual functions of flipping and opening / closing, which can not only be used for straight rail windows, but also be applied to curved rail windows, thus overcoming the deficiencies of the existing technology.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A bendable rail vertical curtain control device integrating the dual functions of flipping and opening / closing, comprising

[0008] A rail, which has a first end and a second end, and double gear transmission mechanisms are respectively provided on the first end and the second end. A flipping belt is sleeved on the first gear of the double gear transmission mechanism, and an opening / closing belt is sleeved on the second gear.

[0009] Multiple ball running mechanisms. Adjacent pairs of ball running mechanisms are connected by flat belts to form a ball running string. Each ball running mechanism has a ball running hole belt gear connected to a reversing belt. A first ball running transmission gear for transmission is provided in the middle of the ball running hole belt gear. The first ball running transmission gear meshes with a second ball running transmission gear for clutch function. The center of the second ball running transmission gear is connected to a ball running blade holder. The ball running blade holder is detachably installed with a vertical curtain hanging hook. A pulley component is installed on the ball running mechanism at the end of the ball running string and is fixed to the opening and closing belt through the pulley component.

[0010] A driving mechanism, including a driving motor and a driving rod. The driving motor drives the driving rod to rotate. An electromagnet is provided on the driving rod, and a driving head is installed on the electromagnet. The driving head is driven by the electromagnet to have a first stroke and a second stroke, and there is a height difference between the first stroke and the second stroke.

[0011] The driving mechanism is detachably assembled to one set of double gear transmission mechanisms. The first gear and the second gear in the double gear transmission mechanisms are matched with the first stroke and the second stroke.

[0012] When the first stroke of the driving head extends into the first gear, the driving head only meshes with the first gear. At this time, the driving motor rotates to drive the reversing belt, and the ball running hole belt gears of each ball running mechanism are dragged, and finally the vertical curtain hanging hooks are driven to rotate automatically to realize the flipping of the vertical curtain.

[0013] When the second stroke of the driving head extends into the second gear, the driving head meshes with the first gear and the second gear at the same time. At this time, the driving motor drives the reversing belt and the opening and closing belt at the same time. The reversing belt drives the vertical curtain hanging hooks on each ball running mechanism to rotate automatically to realize the flipping of the vertical curtain. At the same time, the opening and closing belt drags the pulley component of the ball running mechanism at the end of the ball running string to drive the ball running string to fold or unfold with each other, realizing the opening and closing of the vertical curtain.

[0014] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

[0015] First, the present invention only uses one driving motor, and then designs a driving head with two-stage strokes, and cooperates with a double-gear transmission mechanism of double belts. When the first stroke of the driving head extends into the first gear, the driving head only meshes with the first gear. At this time, the driving motor rotates to drive the flipping belt, and the beaded hole belts of each beading mechanism are dragged, and finally the vertical curtain hooks are driven to rotate self to realize the flipping of the vertical curtain. When the second stroke of the driving head extends into the second gear, the driving head meshes with the first gear and the second gear at the same time. At this time, the driving motor drives the flipping belt and the opening and closing belt at the same time. The flipping belt drives the vertical curtain hooks on each beading mechanism to rotate self to realize the flipping of the vertical curtain. At the same time, the opening and closing belt drags the pulley component of the beading mechanism at the end of the beading string, driving the beading strings to fold or unfold with each other, and realizing the opening and closing of the vertical curtain. Thus, it can be seen that the driving head of the driving mechanism of the present invention has two strokes. According to different situations, it can only drive the flipping of the curtain sheet, or can drive the flipping and opening and closing of the curtain sheet at the same time.

[0016] Second, due to the double-belt design, one is the flipping belt and the other is the opening and closing belt. Since the belt has flexibility, it can be used for windows with curved shapes, such as a bay window in the shape of a "convex", or various shaped bay windows such as arched or "┑" shaped. Moreover, the beading mechanism runs very smoothly on the curved track without jamming.

[0017] Furthermore, the vertical curtain hooks of the present invention can be separated from the beaded blade frame. Therefore, during the shipping process, the vertical curtain hooks can be not installed first, avoiding the breakage and damage of the protruding vertical curtain hooks during transportation. The separable design allows the installation of the vertical curtain hooks after the entire device is installed, avoiding damage during transportation.

[0018] In addition, since the adjacent beading mechanisms of the present invention are side-lying through flat belts, the device can achieve curved rail transmission.

[0059] Please refer to Figures 1 to 13 As shown, it shows the specific structure of a preferred embodiment of the present invention, which is a bendable track vertical curtain control device with integrated flip opening and closing dual functions, including a track 10, a double gear transmission mechanism 20 arranged at both ends of the track 10, a plurality of ball mechanisms 30 arranged in the track 10, and a driving mechanism 40 for assembling with the double gear transmission mechanism 20 and driving each ball mechanism 30.

[0060] Among them, the track 10 has a first end 11 and a second end 12. Double gear transmission mechanisms 20 are respectively provided on the first end 11 and the second end 12. A flipping belt 22 is sleeved on the first gear 21 of the double gear transmission mechanism 20, and an opening and closing belt 24 is sleeved on the second gear 23. Therefore, when the first gear 21 rotates, it will drive the flipping belt 22, and the flipping belt 22 is ultimately used to realize the flipping of each curtain leaf of the vertical curtain, so as to adjust the angle of each curtain leaf to adjust the light brightness of the curtain. When the second gear 23 rotates, it will drive the opening and closing belt 24, and the opening and closing belt 24 is ultimately used to realize the unfolding or folding of the vertical curtain, so as to realize the opening and closing of the curtain in an actuated manner. When opening, each curtain leaf is laid flat, and after closing, each curtain leaf is folded to one side. One application is that when there are two groups of curtain leaves, the two groups of curtain leaves are respectively folded and close to the left and right sides of the window, so as to realize the effect of opening the curtain.

[0061] As Figures 8 to 13 shown, a plurality of bead mechanisms 30 are installed in the track 10, and each bead mechanism 30 can hang a vertical curtain leaf. Adjacent bead mechanisms 30 are connected by a flat belt 38 to form a bead string, so as to realize the one-time control of all bead mechanisms 30 in a stringed manner, and realize the flipping and opening and closing of the curtain leaves.

[0062] Specifically, each bead mechanism 30 has a bead hole belt gear 31 connected to the flipping belt 22. A first bead transmission gear 32 for transmission is provided in the middle of the bead hole belt gear 31. The first bead transmission gear 32 meshes with a second bead transmission gear 33 for clutch, and the center of the second bead transmission gear 33 is connected to a bead blade holder 34. The bead blade holder 34 is detachably installed with a vertical curtain hook 35; a pulley component 36 is erected on the bead mechanism 30 at the end of the bead string, and is fixed to the opening and closing belt 24 through the pulley component 36.

[0063] During operation, the flipping belt 22 drags the beaded hole belt gears 31 to rotate. The beaded hole belt gears 31 drive the first beaded transmission gear 32, which in turn drives the second beaded transmission gear 33, and then drives the beaded blade holder 34 to rotate. Finally, the vertical curtain hook 35 rotates, so that the curtain leaves hanging on the vertical curtain hook 35 flip accordingly. Since the second beaded transmission gear 33 has a clutch function, when the curtain leaves flip to a certain angle and reach the extreme position, they will no longer continue to flip. At this time, the second beaded transmission gear 33 idles and no longer drags the beaded blade holder 34. This is because the second beaded transmission gear 33 and the beaded support 37 have two states: "disengaged" and "engaged". When the state is "disengaged", the second beaded transmission gear 33 idles; when the state is "engaged", the second beaded transmission gear 33 can drag the beaded blade holder 34 to rotate. The clutch function of the second beaded transmission gear 33 is achieved by the mutual matching of the first boss provided on the second beaded transmission gear 33 and the second boss 371 provided on the beaded support 37.

[0064] As Figures 5 to 7 shown, the driving mechanism 40 is used to be installed on the double-gear transmission mechanism 20, and with its double-stroke design, it can achieve a dual-functional driving effect. Its structure includes a driving motor 41 and a driving rod 42. The driving motor 41 drives the driving rod 42 to rotate, and an electromagnet 43 is provided on the driving rod 42. A driving head 44 is installed on the electromagnet 43. The driving head 44 is driven by the electromagnet 43 and has a first stroke A and a second stroke B, and there is a height difference between the first stroke and the second stroke.

[0065] The driving mechanism 40 is detachably assembled to one group of the double-gear transmission mechanisms 20. The first gear 21 and the second gear 23 in the double-gear transmission mechanism 20 are matched with the first stroke and the second stroke. When the first stroke of the driving head 44 extends into the first gear 21, the driving head 44 only meshes with the first gear 21. At this time, the driving motor 41 rotates to drive the flipping belt 22, and the beaded hole belt gears 31 of each beaded mechanism 30 are dragged, and finally the vertical curtain hook 35 rotates self-driven to realize the flipping of the vertical curtain. When the second stroke of the driving head 44 extends into the second gear 23, the driving head 44 meshes with the first gear 21 and the second gear 23 at the same time. At this time, the driving motor 41 drives the flipping belt 22 and the opening and closing belt 24 at the same time. The flipping belt 22 drives the vertical curtain hook 35 on each beaded mechanism 30 to rotate self-driven to realize the flipping of the vertical curtain. At the same time, the opening and closing belt 24 drags the pulley component 36 of the beaded mechanism 30 at the end of the beaded string, driving the beaded strings to fold or unfold with each other, and realizing the opening and closing of the vertical curtain. Thus, it can be seen that the driving head 44 of the driving mechanism 40 of the present invention has two strokes. According to different situations, it can only drive the flipping of the curtain leaves, or can also drive the flipping and opening and closing of the curtain leaves at the same time.

[0066] AsFigure 3 As shown, the drive mechanism 40 is detachably mounted on the double-gear transmission mechanism 20. The drive mechanism 40 is provided with a latch 45, a positioning pin 46, and a plug connector 47, and the corresponding double-gear transmission mechanism 20 is provided with a latch hole 201, a positioning pin hole 202, and a plug interface 203. The latch 45 is paired with the latch hole 201, the positioning pin 46 is paired with the positioning pin hole 202, and the plug connector 47 is paired with the plug interface 203. This design not only realizes the mechanical connection between the drive mechanism 40 and the double-gear transmission mechanism 20 but also realizes the electrical connection.

[0067] As Figure 5 shown, the double-gear transmission mechanism 20 is disposed in the internal space of the end head body. The internal space of the end head body is assembled with parts in the order of the first bearing 25, the first gear 21, the second bearing 26, the second gear 23, and the third bearing 27. The end head body is provided with an upper end head bracket 28 and a lower end head bracket 29, and a circuit board for the motor interface is disposed between the upper end head bracket 28 and the lower end head bracket 29. Each bearing plays a lubricating role to prevent frictional noise during rotation, and can also realize the isolation between the first gear 21 and the second gear 23 to avoid mutual interference.

[0068] As Figure 4 shown, the first gear 21 is a synchronous hole pulley with engaging teeth 211 on its surface. The flipping belt 22 has belt holes 221, and each engaging tooth 211 is snapped into the belt holes 221 to form an engagement. The second gear 23 is a synchronous toothed belt pulley with external tooth grooves 231 on its surface. The inner side of the opening and closing belt 24 has inner tooth grooves 241, and each inner tooth groove 241 forms an engagement with each external tooth groove 231. By using two different types of the first gear 21 and the second gear 23 and then respectively matching different flipping belts 22 and opening and closing belts 24, each component of the present device makes full use of the narrow space inside the track 10, and can be assembled, transmitted, and has good performance. As Figure 8 shown, each ball mechanism 30 is disposed in the narrow space inside the double belt, and the layout is very compact without wasting space. Therefore, the size of the device of the present invention can be smaller.

[0069] As Figures 5 to 7 shown, an electromagnet 43 is provided on the drive rod 42 of the drive motor 41. The electromagnet switches between the energized and de-energized states and moves up and down. When the electromagnet moves downward, the drive head (44) is in the first stroke, and when the electromagnet moves upward, the drive head (44) is in the second stroke. In this way, the up and down movement of the electromagnet 43 is simply realized, and the structure is novel and reasonable. Figure 6 The state is shown when the drive head 44 moves downward so that the first stroke A engages with the first gear 21. Figure 7The state is shown when the driving head 44 moves upward so that the second stroke B is engaged with the first gear 21 and the second gear 23 at the same time.

[0070] like Figure 9 and Figure 10 As shown, each flat belt 38 of the ball chain is lying on its side, one end of the flat belt 38 is fixed to the flat belt bracket of the corresponding ball mechanism 30, and the other end is slidably connected to the flat belt bracket of the next adjacent ball mechanism 30. This side-lying design direction enables the device to realize curved track transmission. Even if the entire window is curved, these flat belts 38 can deform along the curved track without any jamming problem. However, the traditional flat flat belt cannot realize the curved track transmission function.

[0071] like Figure 11 As shown, the ball mechanism 30 has a ball bracket 37, and the four corners of the ball bracket 37 are provided with ball wheels 372, and the ball wheels 372 are slidably installed inside the track 10, so that the ball mechanism 30 can slide smoothly inside the track 10. In addition, the vertical curtain hook 35 is detachably connected to the ball blade frame 34, and the vertical curtain hook 35 is a metal hook. The traditional vertical curtain hook is integrated with the ball blade frame and is made of plastic. Because the vertical curtain hook 35 extends out of the track 10, it is often broken and damaged due to bumps during packaging and transportation. Now it is changed to a detachable design, which can be assembled later, and the metal material also avoids the problem of breakage. The specific structure is that the upper end of the vertical curtain hook 35 is an upper spring piece 351 formed by folding, and the upper spring piece 351 is folded into a buckle 352; the lower end is a hook body 353 formed by folding, and an anti-drop sheet 354 is folded out after a part of the hook body 353 is torn; the lower end of the ball bearing blade frame 34 is provided with an intermediate connecting column 341, and the connecting column 341 is provided with a buckle hole 342. When the upper spring piece 351 is inserted into the inside of the connecting column 341, the buckle 352 and the buckle hole 342 are buckled together to form a detachable and stable connection.

[0072] like Figure 12 and Figure 13As shown, the pulley component 36 on the bead mechanism 30 at the end of the bead string includes a bead connecting frame 361, a pulley dragging clip 362, a pulley buckle 363, and a pulley frame 364. The bead mechanism 30 is installed on the bead connecting frame 361. There are two pulley frames 364, which are installed on the bead connecting frame 361. The pulley dragging clip 362 is horizontally inserted into the through hole of the pulley frame 364. There is a card slot on the pulley dragging clip 362 for biting the opening and closing belt 24. The pulley buckle 363 is buckled on the sliding dragging clip to firmly connect the opening and closing belt 24. In this way, the bead structure at the end of the bead string can be dragged by the opening and closing belt 24. And, the connecting arm of the bead connecting frame 361 is a multi-section articulated structure, which avoids the non-bendable rail transmission caused by the over-long, over-straight and non-bendable connecting arm of the bead connecting frame 361.

[0073] As described above, it is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
