Description

TECHNICAL FIELD

[0001] This application is a divisional application of the original application with the application number 202111164412.5 and the filing date of September 30, 2021, and the title of "An Electric Curtain Device". BACKGROUND

[0002] The demand for the diversity of curtain lighting makes the adjustable light curtain popular. The adjustable light curtain mainly adjusts the amount of light passing through by adjusting the angle of the curtain. With the continuous improvement of the automation degree of home products, the light adjustment of the curtain also tends to be automatically controlled. The car of the embedded curtain track is installed in the track, and the hook is stretched out from the gap of the track. The curtain is hung on the hook. The hook of the vertical curtain can generally rotate within a certain angle to adjust the gap between the curtain pieces. The hooks of the vertical curtain are generally driven to rotate synchronously by the transmission rod. The transmission rod is also arranged inside the track and is driven to rotate by the motor. The pursuit of large light area in modern buildings makes the width of the curtain further increase. Correspondingly, the length of the transmission rod in the curtain track also needs to be lengthened. However, the lengthening of the transmission rod leads to the bending of the middle part of the transmission rod. When the bending exceeds a certain degree, the transmission rod often falls out of the gap of the track, affecting the normal use of the vertical curtain. SUMMARY

[0003] The purpose of the present application is to provide a support and fixing structure suitable for an electric curtain, which is simple, small and easy to operate, and can effectively support a relatively long transmission rod to prevent the transmission rod from bending.

[0004] Based on this, the present application provides a support and fixing structure suitable for an electric curtain, which comprises a locking support arranged in the track body. The locking support comprises a supporting component, which is located in the track body. The supporting component is provided with a supporting part for supporting the transmission rod.

[0005] The support and fixing structure suitable for an electric curtain as described above, wherein the supporting component is in a flat shape that can pass through the opening slot of the track body.

[0006] The support and fixing structure suitable for an electric curtain as described above, wherein the supporting component is in a flat ⊥ shape, and the ⊥ shape structure forms two supporting parts.

[0007] The support and fixing structure suitable for an electric curtain as described above, further comprising an operating component, which comprises a blocking part and a connecting part connected to each other. The connecting part can pass through the opening slot of the track body, so that the blocking part can extend out of the opening slot of the track body. The connecting part is connected to the supporting component, so that a clamping gap capable of accommodating the bottom edge of the track body is formed between the blocking part and the supporting component.

[0008] The connecting portion can rotate in the opening groove of the track body.

[0009] The embodiment of the present application has the following beneficial effects:

[0010] The present application provides a support structure for an electric curtain. When a transmission rod needs support, a locking support is inserted into the curtain track from the hook gap of the position needing support, and the locking support is engaged on the track body. The transmission rod falls into the bearing part of the bearing component, thereby supporting the middle position of the longer transmission rod, preventing the middle part from bending due to the length of the transmission rod, and preventing the problem of easy falling during normal transmission.

[0036] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0037] Specifically, as Figures 14 to 16 , the locking support 16 comprises an operating part 161 and a supporting part 162, the operating part 161 comprises a blocking part 1611 and a connecting part 1612 connected with each other, the connecting part 1612 can pass through the opening slot 113 of the track body 11, the size of the blocking part 1611 is larger than the opening slot 113, so that the blocking part 1611 can extend out of the opening slot 113 of the track body 11, the connecting part 1612 is connected with the middle part of the supporting part 162, so that the blocking part 1611 and the supporting part 162 form a clamping gap capable of accommodating the bottom edge of the track body 11; the supporting part 162 is in a flat shape capable of passing through the gap of the curtain rail upper hook 15, and the supporting part 162 is provided with a supporting part 1621 for supporting the transmission rod 13.

[0038] After the supporting part 162 passes through the opening slot 113 of the track body 11 and extends into the inner cavity of the track body 11 in a flat posture, and after the blocking part 1611 is rotated by 90 degrees, the connecting part 1612 is located in the opening slot 113, the bottom edge of the track body 11 is just clamped in the clamping gap between the blocking part 1611 and the supporting part 162, and at the same time, the transmission rod 13 just falls on the supporting part 1621, thereby playing a supporting role on the transmission rod 13; moreover, since the locking support 16 is fixed on the track body 11, the sliding of the trolley 14 in the track body 11 can be blocked, the trolley 14 on the track body 11 can be divided into left and right sides, the curtain can be opened and closed on both sides, and the trolley 14 located in the middle can be limited; the disassembly process is opposite, only the blocking part 1611 needs to be rotated by 90 degrees to be parallel to the opening slot 113 of the track body 11, so that the locking support 16 can be detached from the track body 11, without any additional tools.

[0039] In the embodiment, the supporting part 162 is in the shape of a flat ⊥, and the ⊥ shape structure forms exactly two supporting parts 1621, so that the transmission rod 13 can fall into one of the supporting parts 1621 no matter which direction the blocking part 1611 rotates by 90 degrees. A friction sleeve 163 is sleeved on the blocking part 1611, and friction teeth 1631 are engraved on the position of the friction sleeve 163 in contact with the bottom edge of the track body 11 to increase the friction and prevent the locking support 16 from sliding on the track body 11. Meanwhile, the friction sleeve 163 also facilitates the rotation of the blocking part 1611. The friction sleeve 163 can be made of rubber or plastic.

[0040] In the embodiment, the connecting part 1612 is in the shape of a column, and the connecting part 1612 can rotate arbitrarily in the opening slot 113 of the track body 11. The blocking part 1611 and the connecting part 1612 are integrally arranged, a connecting hole 1622 adapted to one end of the connecting part 1612 is arranged on the supporting part 162, a threaded hole (such as the second threaded hole 1623 in Figure 4 ) is further arranged at the bottom of the connecting hole 1622, and a threaded hole (such as the first threaded hole 1613 in Figure 4 ) is arranged in the connecting part 1612. After the connecting part 1612 is inserted into the connecting hole 1622, a long screw 164 is used to connect the connecting part 1612 by passing through the two threaded holes (the first threaded hole 1613 and the second threaded hole 1623) in sequence, thereby improving the firmness of the connection.

[0041] In order to facilitate installation and disassembly, in the embodiment, as shown in Figure 7 , the two ends of the track body 11 are also respectively and simultaneously provided with the above-mentioned locking supports 16 near the positions of the outermost trolleys 14, so as to block the sliding of the outermost trolleys 14. The locking supports 16 lock the two trolleys 14 located at the outermost positions at the two ends of the track body 11, so as to prevent light leakage on both sides of the curtain. The installation position of the locking support 16 is close to the trolleys 14 at the outermost positions, and is close to the wall bodies on both sides of the curtain as much as possible, so that the positions of the trolleys 14 at the outermost positions are fixed and cannot move along the track body 11. The above-mentioned locking support 16 can also be installed at any position of the track body 11 according to the actual application scene of the user.

[0042] The application also provides an electric curtain device with the supporting and fixing structure, as shown in Figure 1 , Figure 17 , which comprises a track assembly 1 and a driving assembly 2. As shown in Figure 7 , the track assembly 1 comprises a track body 11 and a transmission belt 12, a transmission rod 13, a trolley 14, a linkage piece 18, a hook 15 and a locking support 16 arranged in the track body 11.

[0043] As shown in Figure 2、 Figure 3 As shown in the drawings, the track body 11 is a hollow structure 131, and in this embodiment, rubber strips 19 are also arranged in the track body 11. The cross section of the track body 11 is substantially rectangular, and four corners of the rectangle are respectively provided with accommodating grooves. The two accommodating grooves at the upper part are first accommodating grooves 111, and the two accommodating grooves at the lower part are second accommodating grooves 112. Figure 7 、 Figure 23 The track body 11 is provided with a driving pulley 121 and a driven pulley at positions close to the top surface at both ends, respectively. The transmission belt 12 is wound around the driving pulley 121 and the driven pulley, and also wound around the two first accommodating grooves 111 on the track body 11. The transmission belt 12 runs in the horizontal direction under the driving of the driving pulley 121. The first accommodating grooves 111 are provided with avoiding notches 1111 for avoiding the connection of the connecting pieces 17 connected with the transmission belt 12.

[0044] The second accommodating grooves 112 of the track body 11 are provided with openings 1121. The rubber strips 19 include integrated embedding parts 191 and abutting parts 192. The embedding parts 191 are adapted to the size of the second accommodating grooves 112 and the openings 1121 thereon. The embedding parts 191 are embedded in the second accommodating grooves 112. The two rubber strips 19 are fixed on the two second accommodating grooves 112 through the embedding parts 191, respectively. The abutting parts 192 of the rubber strips 19 are in contact with the inner side surface and the inner bottom surface of the track body 11. The transmission rod 13 and the trolley 14 will collide with the track body 11 and the components connected thereto when running, thereby generating noise. The rubber strips 19 are arranged on the inner side of the track body 11, which can reduce the noise generated when the transmission rod 13 and the like run.

[0045] As shown in the drawings, Figure 2 、 Figure 3 The two inner side surfaces of the track body 11 are symmetrically provided with rib plates 114. The upper edges of the abutting parts 192 of the rubber strips 19 abut on the lower surfaces of the rib plates 114, thereby limiting the rubber strips 19. Meanwhile, the two sides of the trolley 14 are provided with pulleys 142. The two pulleys 142 run on the upper surfaces of the rib plates 114 at the two sides.

[0046] The top surface of the track body 11 is extended with a protruding edge 115 along the two sides of the length of the track. The protruding edge 115 is along the length direction of the track body 11. The protruding edge 115 is used for clamping with the top mounting plate 3 of the curtain track. The top mounting plate 3 is provided with a clamping groove 31 adapted to the protruding edge 115. When installing, the clamping groove 31 of the top mounting plate 3 is only needed to be slid along the protruding edge 115 of the track body 11, so that the top mounting plate 3 is clamped on the track body 11. The installation is convenient, and no additional installation tools such as screws are needed.

[0047] The transmission rod 13 is rotatably mounted below the transmission belt 12 and parallel to the track body 11, located in the middle of the cavity of the track body 11. Figure 3 , Figure 4 Several trolleys 14 are mounted on the transmission rod 13 and can move along the transmission rod 13. The external shape of the trolleys 14 is adapted to the internal cavity of the track body 11, so that the trolleys 14 can move and pass through the cavity of the track body 11. A transmission structure 144 is provided inside the trolley 14, and the hook 15 is connected to the transmission structure 144. The transmission structure 144 is also connected to the transmission rod 13. The transmission structure 144 converts the vertical rotation of the transmission rod 13 into the horizontal rotation of the hook 15.

[0048] The transmission structure 144 can adopt existing structures or forms capable of transmitting power between two intersecting shafts, such as a worm gear and turbine structure, or a two-bevel gear structure. As one such form, in this embodiment, for example... Figure 5 , Figure 6 The transmission structure 144 is mainly a turbine and worm structure, including a meshing turbine 1442 and a worm 1441. The worm 1441 is a hollow shaft structure with conventional helical teeth that mesh with the turbine 1442 on its outer surface. The hollow shaft of the worm 1441 has a shape that matches the outer cross-section of the transmission rod 13, or a bushing 1443 is fitted inside the hollow shaft of the worm 1441. The bushing 1443 has a shape that matches the outer cross-section of the transmission rod 13. The worm 1441 is fitted onto the transmission rod 13 through the cooperation of the hollow shaft or bushing 1443, and can move along the direction of the transmission rod 13. The transmission rod 13 drives the worm 1441 to rotate through the cooperation of the hollow shaft or bushing 1443. As one example, as shown in the figure, the transmission rod 13 is a hexagonal rod, and a bushing 1443 is fitted onto the hollow shaft of the worm gear 1441. The inner surface of the bushing 1443 is also hexagonal. The transmission rod 13 drives the worm gear 1441 to rotate through the bushing 1443. The hook 15 is connected to the turbine 1442 and is coaxially arranged with the turbine 1442. When the transmission rod 13 rotates in the vertical direction, it drives the worm gear 1441 to rotate in the vertical direction. The worm gear 1441 drives the turbine 1442 and the hook 15 to rotate in the horizontal direction.

[0049] In this embodiment, the trolley 14 comprises a trolley body 141 and a linkage plate receiving plate 143 in addition to the transmission structure 144 and the pulley 142. The trolley body 141 is provided with a space and structure corresponding to the installation of the transmission structure 144. The pulley 142 is installed on both sides of the trolley body 141 and travels along the rib plate 114 on the inner side of the track body 11. The linkages 18 are installed on the linkage plate receiving plate 143 and are connected in front and back. The first trolley 140 is connected to the transmission belt 12 through the connecting piece 17. The connecting piece 17 connects the first trolley 140 and the transmission belt 12. One end of the connecting piece 17 is connected to the transmission belt 12 and the other end is connected to the first trolley 140. In this embodiment, the connecting piece 17 comprises a belt clamping piece 171, a connecting plate 172 and a connecting column 173. The belt clamping piece 171 is clamped on one side of the transmission belt 12. The belt clamping piece 171 is connected to the upper surface of the connecting plate 172. One end of the connecting column 173 is connected to the lower surface of the connecting plate 172 and the other end is connected to the first trolley 140.

[0050] The bottom of the track body 11 is provided with an open slot 113 allowing the hook 15 to pass through. One end of the hook 15 is connected to the transmission structure 144 and the other end extends out of the open slot 113. The hook 15 is used to hang the curtain. Figures 7 to 9 The locking support 16 is installed at the middle position of the sliding groove body. The locking support 16 mainly plays the role of supporting and locking the partition. The locking support 16 blocks the trolley 14 from passing through. Several trolleys 14 are separated on the left and right sides of the locking support 16, so that the whole curtain is divided into left and right sides. At the same time, the transmission rod 13 is supported on the locking support 16, which plays the role of middle support for the transmission rod 13. The two trolleys 14 on both sides of the locking support 16 are the first trolley 140, that is, there is one first trolley 140 on each side. The two first trolleys 140 are connected to two different sides of the transmission belt 12 through the connecting piece 17. In this way, when the transmission belt 12 rotates, the two sides move in different directions, driving the two first trolleys 140 to move in opposite directions, realizing the opening and closing of the curtain on both sides at the same time. The remaining trolleys 14 on both sides of the locking support 16 are connected in sequence with the first trolley 140 on the same side through the linkage 18. The first trolley 140 drives the remaining trolleys 14 and the hook 15 connected to the trolley 14 to move in sequence to realize the opening and closing.

[0051] As one of the embodiments, in this embodiment, Figure 2 , Figure 10The transmission rod 13 has a hollow structure 131. Two transmission rods 13 are connected by a connecting strip 20. The cross-section of the connecting strip 20 is adapted to the cross-section of the hollow structure 131 of the transmission rod 13. The connecting strip 20 achieves the internal connection of the transmission rods 13 by inserting its two ends into the two transmission rods 13 respectively. The hollow structure 131 of the transmission rod 13 can achieve internal connection. The advantage of internal connection is that it does not affect the back and forth passage of the trolley 14, and can increase the width of the curtain. Another advantage of the hollow structure 131 is that it can increase the outer diameter of the transmission rod 13 while reducing the weight of the transmission rod 13, thereby increasing its rigidity and reducing the probability of it bending. The increase in outer diameter also makes it less likely to fall out of the opening slot 113.

[0052] The transmission rod 13 can be a hollow hexagonal rod, rectangular rod, or splined rod. The cross-section of its hollow structure 131 can be hexagonal, rectangular, floral, or circular. The connecting strip 20 is hexagonal, rectangular, floral, or circular, and its cross-section matches the cross-section of the hollow structure 131 of the transmission rod 13. Combining these two elements allows for various implementation methods, such as... Figure 2 , Figure 10 The hollow interior shown is also a hexagonal rod, such as... Figure 11 The hexagonal bar shown has a rectangular hollow interior, as... Figure 12 The spline bar shown has a hollow hexagonal interior, as... Figure 13 The spline bar shown has a rectangular hollow interior.

[0053] like Figure 1 , Figure 17 The drive assembly 2 is located at one end of the track body 11 near the drive pulley 121. The drive assembly 2 includes an opening / closing drive component 21 and a dimming drive component 22.

In this embodiment, the opening / closing motor assembly includes an opening / closing motor 211 and an opening / closing motor gearbox 212 mounted coaxially. The opening / closing motor gearbox 212 can also be coaxially connected to a clutch 219, and the output shaft of the clutch 219 is then connected to the opening / closing transmission gear assembly. A first O-ring 218 is provided at the connection between the opening / closing motor 211 and the opening / closing motor gearbox 212 for vibration damping and noise reduction during operation.

[0054] like Figure 18 , Figure 19 The dimming drive component 22 includes a dimming motor assembly and a dimming transmission gear set connected to each other. The dimming motor assembly includes a dimming motor 221 and a dimming motor gearbox 222 mounted on the same axis. A second O-ring 226 is also provided at the connection between the dimming motor 221 and the dimming motor gearbox 222 for vibration reduction and noise reduction during operation.

[0055] The opening and closing motor assembly is linear and parallel to the track body 11. The light adjusting motor assembly is linear and perpendicular to the track body 11. The opening and closing motor assembly and the light adjusting motor assembly are arranged in an L shape, and the opening and closing transmission gear set is located directly above the light adjusting driving part 22.

[0056] As one of the embodiments, the opening and closing transmission gear set includes a gear set and two second bevel gears, i.e., a second bevel gear one 213 and a second bevel gear two 214, which are meshed with each other. The gear set includes a plurality of transmission gears which are sequentially meshed with each other. The transmission gear close to the opening and closing motor assembly is an input gear 215, and the transmission gear close to the driving pulley 121 of the main driving belt 12 is an output gear 217.

Compared with the turbine worm transmission mode, the transmission of the above transmission structure is more efficient and saves more space. In the embodiment, the gear set includes three transmission gears, i.e., the input gear 215, an intermediate gear 216 and the output gear 217, and the transmission gears are all straight gears. The included angle of the pitch cone angle of the second bevel gear one 213 and the second bevel gear two 214 is 45°.

[0057] The light adjusting transmission gear set includes two first bevel gears, i.e., a first bevel gear one 223 and a first bevel gear two 224, which are meshed with each other.

Figures 18 to 21The light-adjusting driving component 22 further comprises an L-shaped bottom plate 23 and an L-shaped upper cover 24, and the length of one arm of the L-shaped plate is longer than that of the other arm. Generally, the length of the light-adjusting motor assembly is shorter than that of the opening-closing motor assembly. The opening-closing motor assembly is mounted on the long arm of the L-shaped bottom plate 23, and the light-adjusting motor assembly is mounted on the short arm of the L-shaped bottom plate 23. The upper cover 24 is fastened on the upper portion of the bottom plate 23, and the opening-closing motor assembly and the light-adjusting motor assembly are both covered inside. The upper cover 24 is provided with a mounting groove 241 above the light-adjusting driving component 22, and the opening-closing transmission gear set is mounted in the mounting groove 241, so as to realize modular positioning.

[0059] Meanwhile, as shown in Figures 22 to 24 The driving assembly 2 is further provided with a mounting positioning box 25, and the mounting positioning box 25 is provided with a first mounting structure 251 for mounting the transmission rod 13 and the upper second bevel gear 214 of the light-adjusting transmission gear set, and a second mounting structure 252 for mounting the driving pulley 121 of the transmission belt 12 and the output gear 217 of the opening-closing transmission gear set. In the embodiment, the first mounting structure 251 comprises a supporting portion for supporting the rotating shaft of the second bevel gear 214 and a through hole portion matched with the connecting sleeve 225 of the transmission rod 13, and the second mounting structure 252 comprises a supporting shaft portion for mounting the rotating shafts of the driving pulley 121 and the output gear 217.
