Description

Technical Field

[0001] This invention belongs to the technical field of electric curtains, and particularly relates to a split-type curtain track. Background Technology

[0002] Smart home is a home ecosystem comprised of hardware, software systems, and cloud platforms, utilizing Internet of Things (IoT) technology to provide users with a safe, convenient, and comfortable home living environment. In recent years, with the development of smart homes, in addition to intelligent home appliances, smart home products have also expanded to include intelligent lighting, intelligent shading, and more.

[0003] Electric curtains are widely used because they are electrically controlled by motors, eliminating the hassle of manual opening and closing, and align with the development trend of smart homes. The size of electric curtains is customized according to the installation location. For excessively long curtains, they are generally divided into multiple sections and then assembled on-site. To ensure that the curtain hanging components of multi-section electric curtains operate synchronously after installation, existing multi-section electric curtains, although their shells are also separate, use a single opening and closing transmission mechanism to move the curtain hanging components. This mechanism typically uses a timing belt and drive wheels, meaning that although the shells are separate, they are actually connected by a timing belt. This results in limitations on the placement of the separate shells during transportation or handling. Furthermore, the timing belt is exposed before the shells are joined, making it susceptible to damage. Moreover, to facilitate the separation of the shells, the length of the timing belt needs to be readjusted after the shells are joined. Therefore, segmented electric curtains are inconvenient to transport and the assembly process is complex. Summary of the Invention

[0004] The purpose of this invention is to provide a split curtain rail that allows for direct connection and use of segmented curtain rails, making it easy to install and highly efficient.

[0005] Based on this, the present invention provides a split curtain track, including a first curtain track and a second curtain track;

[0012] As described above, a split-type curtain rail is further provided with a rotatable first hook connected to the trolley body. The first curtain rail also includes a first angle adjustment transmission component for driving the first hook to rotate.

[0013] The second curtain hanging assembly is provided with a second hook, and the second curtain guide rail also includes a second angle adjustment transmission assembly for driving the second hook to rotate.

[0014] As described above, in a split-type curtain rail, the first angle adjustment transmission component includes a first rotating rod, which is arranged along the length of the first rail housing and passes through the trolley body.

[0015] The first angle adjustment transmission assembly further includes a first transmission inner support disposed in the clearance cavity, and one end of the first rotating rod extends into the clearance cavity and is connected to the first transmission inner support.

[0016] As described above, a split-type curtain track also includes a docking transmission component, which is detachably connected to the first transmission inner support and can rotate with the first transmission inner support.

[0017] When the second connector is connected to the first connector, the first angle adjustment transmission component is connected to the second angle adjustment transmission component through the docking transmission component, and the rotation axis of the first angle adjustment transmission component is collinear with the rotation axis of the second angle adjustment transmission component during docking.

[0018] As described above, in a split-type curtain track, the first opening and closing transmission component includes a first transmission gear, a first docking gear, and a first transmission belt that cooperates with the first transmission gear and the first docking gear, wherein the first docking gear is located on one side of the first connecting end;

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1 to 11As shown, this embodiment of the invention provides a split-type curtain track, including a first curtain track 1 and a second curtain track 2. The first curtain track 1 includes a first track housing 11, a first opening and closing transmission assembly 13 disposed within the first track housing 11, and a first curtain hanging assembly 12. The first opening and closing transmission assembly 13 is used to drive the first curtain hanging assembly 12 to move along the length direction of the first track housing 11. The second curtain track 2 includes a second track housing 21 and a second opening and closing transmission assembly 23 disposed on the second track housing 21. The second curtain hanging assembly 22 and the second opening and closing transmission assembly 23 are used to drive the second curtain hanging assembly 22 to move along the length direction of the second guide rail housing 21. One end of the first curtain guide rail 1 is a first connecting end 14, and one end of the second curtain guide rail 2 is a second connecting end 24. The second connecting end 24 is detachably connected to the first connecting end 14, and when the second connecting end 24 is connected to the first connecting end 14, the first opening and closing transmission assembly 13 is connected to the second opening and closing transmission assembly 23 on the first connecting end 14. This invention provides a split curtain guide rail, in which both the split first curtain guide rail and the second curtain guide rail are equipped with opening and closing transmission assemblies. Unlike the prior art, the split state does not require connection through a synchronous belt, making the split first curtain guide rail and the second curtain guide rail more flexible and unrestricted during transportation or placement. Moreover, after the first curtain guide rail and the second curtain guide rail are connected to each other, the first opening and closing transmission assembly can be connected to the second opening and closing transmission assembly to directly complete the transmission connection, making installation more convenient and efficient.

[0038] In this embodiment of the invention, after the second connecting end 24 is connected to the first connecting end 14, the first curtain rail 1 and the second curtain rail 2 are connected in a straight line. This solution is used for the horizontal straight connection of two or more curtain rails, and through this connection method, the first opening and closing transmission component 13 and the second opening and closing transmission component 23 are connected in a straight line.

[0039] In this embodiment of the invention, the first connecting end 14 is provided with a first end cap 141 connected to the first guide rail housing 11. The first end cap 141 is provided with a first mounting cavity 1431 for the first opening and closing transmission assembly 13 to be installed, and a clearance cavity 1432 located on the lower side of the first mounting cavity 1431. The first curtain hanging assembly 12 can be embedded into the clearance cavity 1432 to be close to the outer end face 1410 of the first end cap 141.

[0040] Furthermore, the first curtain hanging assembly 12 includes at least a main carriage 121, which includes a carriage body 1211, an insert portion 1212, and a connecting portion 1213. The connecting portion 1213 is used to connect with the first opening and closing transmission assembly 13 so that the main carriage 21 moves with the first opening and closing transmission assembly 13. The insert portion 1212 can extend into the clearance cavity 1432, so that the carriage body 1211 is close to the outer end face 1410 of the first end cover 141. Through the improvement of this main carriage structure, a clearance cavity is opened on the first end cover 141 for the carriage body and the insert portion to extend into. Thus, when the curtain is closed, the main carriage moves with the first opening and closing transmission assembly. When the position of the connecting portion in the mounting cavity is limited, the distance between the carriage body and the connecting portion is extended by the insert portion. Moreover, when the carriage body is inserted into the clearance cavity 121, it can be closer to the end face of the first end cover, thereby achieving the above-mentioned effect of reducing the gap. Similarly, in this embodiment of the invention, the second curtain rail 2 can also adopt the above structure to make the end face closer to the second end cover, so that when the double curtain is closed, the gap between the two curtains is less or there is no gap, thus achieving a better light blocking effect.

[0041] In this solution, the structural limitations of the traditional first end cap are overcome. The curtain hanging assembly 12 is not limited by the side 100 of the first end cap mounting cavity. A portion of the curtain hanging assembly 12 can be embedded into the inner side of the first end cap through the clearance cavity 1432, thus getting closer to the outer end face 1410. Therefore, "closer to the outer end face 1410" here means that a portion of the curtain hanging assembly 12 can pass through the mounting cavity, or... Figure 10 As shown, it extends deep into the inner side of the first end cap, with only the thickness of the first end cap separating it from the outer end face 1410. Of course, it can also extend directly to the outer end face 1410, achieving a truly gapless connection.

[0042] Of course, the aforementioned clearance cavity design only allows a portion of the curtain hanging component to be embedded, enabling the curtain hanging component to be closer to the outer end face when the curtain is closed. It doesn't necessarily mean it will move to a position where it is blocked by the mounting cavity at side 100; the curtain hanging component could also move directly to contact the inner side of the outer end face, in which case it doesn't actually contact the side 100 of the mounting cavity. For example, see... Figure 10The curtain hanging assembly 12 has a trolley body 1211 connected to a hook, a connecting end 1213 connected to an opening and closing transmission assembly, and an insert 1212 located between the trolley body and the connecting end. In the closed state, the insert 1212 extends into the clearance cavity 1432 so that the trolley body 1211 can be closer to the outer end face 1410. In this solution, it is only necessary to set the distance L1 from the connecting end 1213 to the outer end face of the trolley body 1211 to be greater than or equal to the lateral depth L2 of the clearance cavity 1432 (i.e., the distance from the side 100 of the mounting cavity to the inner side of the outer end face 1410). When L1 = L2, that is, when the trolley body 1211 moves to contact the inner side of the outer end face 1410, the connecting end 1213 contacts the side 100 of the mounting cavity.

[0043] Furthermore, the trolley body 1211 is also connected to a rotatable first hook 91, and the first curtain rail 1 also includes a first angle adjustment transmission component 15 for driving the first hook 91 to rotate; the second curtain hanging component 22 is provided with a second hook 92, and the second curtain rail 2 also includes a second angle adjustment transmission component 25 for driving the second hook 92 to rotate.

[0044] Specifically, the first angle adjustment transmission assembly 15 includes a first rotating rod 152, which is arranged along the length of the first guide rail housing 11 and passes through the trolley body 1211. The first angle adjustment transmission assembly 15 also includes a first transmission inner support 153 disposed within the clearance cavity 1432, with one end of the first rotating rod 152 extending into the clearance cavity 1432 and connecting to the first transmission inner support 153. The main function of the first transmission inner support 153 is that, since the relatively long and straight first rotating rod 152 is disposed within the first guide rail housing 11, if its end is suspended, it will bounce during rotation, affecting rotation and generating noise. This solution supports the end of the first rotating rod 152 through the first transmission inner support 153, and the first transmission inner support 153 can rotate relative to the first guide rail housing 11, thereby achieving a supporting effect. Similarly, a second transmission inner support is also disposed within the second curtain guide rail to achieve the same effect.

[0045] In this embodiment of the invention, a docking transmission component 3 is further included. The docking transmission component 3 is detachably connected to the first transmission inner support 153 and can rotate with the first transmission inner support 153. When the second connecting end 24 docks with the first connecting end 14, the first angle adjustment transmission component 15 is connected to the second angle adjustment transmission component 25 via the docking transmission component 3, and the rotation axis of the first angle adjustment transmission component 15 and the rotation axis of the second angle adjustment transmission component 25 are collinear during docking. The overall structure is simple, and this solution uses the external docking transmission component 3 to enable the first angle adjustment transmission component 15 and the second angle adjustment transmission component 25 to dock and rotate synchronously.

[0046] Specifically, the first opening and closing transmission assembly has the following structure: the first opening and closing transmission assembly 13 includes a first transmission gear 131, a first docking gear 132, and a first transmission belt 133 that cooperates with the first transmission gear 131 and the first docking gear 132, wherein the first docking gear 132 is located on one side of the first connecting end 14.

[0047] The specific structure of the second opening and closing transmission assembly is as follows: the second opening and closing transmission assembly 23 includes a second transmission gear 231, a second docking gear 232, and a second transmission belt 233 that cooperates with the second transmission gear 231 and the second docking gear 232. The second docking gear 232 is located on one side of the second connecting end 24.

[0048] Furthermore, in this embodiment of the invention, the first mating gear 132 is disposed within the first mounting cavity 1431. The first mating gear 132 is provided with a first meshing portion 1321 and a first mating portion 1322 that mesh with the first transmission belt 133. The outer end face 1410 of the first end cover 141 is provided with a first notch 1411 that communicates with the first mounting cavity 1431. One side of the first mating portion 1322 protrudes from the first notch 1411 or is opposite to the first notch 1411. When the second connecting end 24 mates with the first connecting end 14, the second mating portion 2322 and the first mating portion 1322 at the corresponding notch mesh with each other, thereby forming a transmission connection. This simple structural improvement facilitates rapid installation and changes the traditional method of connection via a transmission belt.

[0049] Correspondingly, the second connecting end 24 is provided with a second end cap 241 connected to the second guide rail housing 21, the second docking gear 232 is provided with a second meshing part 2321 and a second docking part 2322 that mesh with the second transmission belt 233, the end face of the second end cap 241 is provided with a second notch 2411, one side of the second docking part 1322 is exposed from the second notch 2411 or opposite to the second notch 2411, and the first notch 1411 and the second notch 2411 are located on the same horizontal plane.

[0050] In this embodiment of the invention, the first curtain rail 1 and the second curtain rail 2 are detachably connected. The first end cap 141 has a connecting portion 142, and the second end cap 241 has a mating portion 242. When the second connecting end 24 mates with the first connecting end 14, the connecting portion 142 and the mating portion 242 are opposite each other. The locking connector 4 is connected to the connecting portion 142 and the mating portion 242. In this solution, the locking connector 4 is a screw, bolt, etc. It connects the first curtain rail 1 and the second curtain rail 2 by passing through the connecting portion 142 and the mating portion 242, and disassembly only requires removing the locking connector 4.

[0051] In this design, connecting portions 142 are provided on both sides of the first end cap 141, and similarly, mating portions 242 are provided on both sides of the second end cap 241. Furthermore, in this design, the connecting portions on both sides can be on the upper side, and the mating portions 242 on both sides. Here, "upper side" and "lower side" refer to the positional relationship between the connecting portions 142 and the mating portions 242 after the first end cap 141 and the second end cap 241 are mated together. Alternatively, one side of the connecting portion can be on the upper side, and the other side on the lower side. This arrangement allows for vertical locking and positioning after the connecting portions 142 and the mating portions 242 on both sides are connected, thus facilitating installation.

[0052] In addition, in this embodiment of the invention, the specific structure of the first angle adjustment transmission component is as follows: the first angle adjustment transmission component 15 includes a first rotating rod 152 and a first transmission inner support 153 disposed on the end of the first rotating rod 152. The first rotating rod 152 is arranged along the length direction of the first guide rail housing 11, and the first rotating rod 152 passes through the first curtain hanging component 12. The first transmission inner support 153 is detachably connected to one end of the docking transmission component 3.

[0053] The specific structure of the second angle adjustment transmission assembly is as follows: The second angle adjustment transmission assembly 25 includes a second rotating rod 252 and a second transmission inner support 253 disposed on the end of the second rotating rod 252. The second rotating rod 252 is arranged along the length direction of the second guide rail housing 21 and passes through the second curtain hanging assembly 22. The second transmission inner support 253 is detachably connected to the other end of the docking transmission member 3.

[0054] In this embodiment of the invention, the first end cap 141 is further provided with a first through hole 1412 and a second through hole 1413. The first through hole 1412 and the second through hole 1413 are located on the end face where the first notch 1411 is located, and the first through hole 1412 and the second through hole 1413 are located on the same horizontal plane and are spaced apart. The first transmission inner support 153 is located on the first through hole 1412 or the second through hole 1413. In this solution, the first angle adjustment transmission component 15 is connected to the outer docking transmission component 3 through the first through hole 1412 or the second through hole 1413. Similarly, the second angle adjustment transmission component 25 is also connected to the docking transmission component 3 in the same way, so that the first angle adjustment transmission component 15 and the second angle adjustment transmission component 25 are connected and transmitted through the docking transmission component 3. Moreover, even when used alone, the first angle adjustment transmission component 15 can operate independently to adjust the angle.

[0055] In addition, the solution provides a first through hole 1412 or a second through hole 1413, which are respectively close to the two sides of the first end cover 141. This can adapt to the structure where the connection position of the first angle adjustment transmission component 15 and the first curtain hanging component 12 is on the left or right side, thus making the solution more versatile.

[0056] Similarly, in this embodiment of the invention, the second end cap 241 is also provided with a third through hole 2412 and a fourth through hole 2413. After docking, the third through hole 2412 is opposite to the first through hole 1412, and the fourth through hole 2413 is opposite to the second through hole 1413.

[0057] Furthermore, in this embodiment of the invention, the outer contour of the first rotating rod 152 is polygonal. By cooperating with the structure on the first curtain hanging assembly 12, the rotation of the first rotating rod 152 drives the first hook 91 on the first curtain hanging assembly 12 to rotate, thereby achieving angle adjustment. In this solution, the outer peripheral surface of the first rotating rod 152 is hexagonal. And in this solution, the structure of the second rotating rod is the same as above, and will not be described in detail here.

[0058] In this embodiment of the invention, the first rotating rod 152 has mounting guide holes 1521 extending along its length and penetrating both ends of the first rotating rod 152. The cross-sectional shape of the mounting guide holes 1521 is polygonal. Furthermore, the first transmission inner support 153 includes a plug-in portion 1531. The outer contour of the plug-in portion 1531 matches the cross-sectional shape of the mounting guide holes 1521, and the plug-in portion 1531 can be inserted into the mounting guide holes 1521. The outward-facing end of the plug-in portion 1531 has a plug-in hole for the insertion of the docking transmission member 3. Its structure is simple and easy to install.

[0059] Furthermore, the first transmission inner support 153 also includes an elastic engagement portion 1532 disposed on the insertion hole, wherein the elastic engagement portion 1532 has a guide hole 1533 communicating with the insertion hole in the middle. The elastic engagement portion 1532 may be made of rubber material, which can adhere tightly to the docking transmission member 3 by its own elasticity after the docking transmission member 3 is inserted, thereby forming a certain resistance to prevent the docking transmission member 3 from loosening, and reducing wear between the docking transmission member 3 and the first transmission inner support 153 during transmission, thus improving service life.

[0060] Furthermore, in this embodiment of the invention, the cross-sectional shape of the insertion hole is polygonal, the docking transmission component 3 is a straight rod, and the outer contour of the docking transmission component 3 matches the cross-sectional shape of the insertion hole. Its structure is simple and easy to install.

[0061] This invention provides a split-type curtain track, in which both the first and second split curtain tracks are equipped with opening and closing transmission components. Unlike existing technologies, which require a synchronous belt connection when the two sections are separate, this design allows for greater flexibility and freedom in handling and placement of the split curtain tracks. Furthermore, after the first and second curtain tracks are connected, the first opening and closing transmission component can directly connect with the second opening and closing transmission component, making installation more convenient and efficient.

[0062] It should be understood that the terms "first," "second," etc., are used in this invention to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.
