Description

Technical Field

[0001] This application relates to the technical field of electric curtains, and in particular to an electric curtain track. Background Technology

[0002] With the development of the times, automation technology is being used more and more in home decoration products. For example, electric curtains are becoming increasingly popular in home decoration products.

[0003] Traditional electric curtains typically consist of a curtain rod, curtain hooks, a drive mechanism, and curtains. The curtains have several pre-installed curtain rings that work with the curtain hooks. By controlling the drive mechanism, the curtain hooks slide along the length of the curtain rod, and the curtain hooks move the curtain rings to raise and lower the curtains.

[0004] The curtain rod of motorized curtains is often a single piece, and the length of the curtain rod is often quite long. The process of transporting the motorized curtains from the factory to the installation point for installation is rather inconvenient and needs improvement. Summary of the Invention

[0005] The purpose of this application is to provide an electric curtain track to solve the problem of the inconvenience of moving curtain rods.

[0006] The electric curtain track provided in this application adopts the following technical solution:

[0007] An electric curtain track includes a curtain rod, a curtain hook slidably disposed on the curtain rod, and a drive structure disposed on the curtain rod for driving the curtain hook to slide. The curtain rod includes at least two guide rails, and adjacent two guide rails are detachably connected by a connector. The drive structure includes a timing belt and a drive member for driving the timing belt. The timing belt has at least two broken ends, and a timing member is fixedly disposed on each broken end. The timing member is detachably connected to the curtain hook.

[0008] By adopting the above technical solution, a curtain rod is divided into multiple guide rails, with each pair of guide rails detachably connected by a connector. Before transportation, the two guide rails are disassembled and bent. Since the timing belt is stretched during the bending process, potentially preventing the two guide rails from bending, the timing belt is designed with a cut end fixed to the timing component. The fixing component is detachably connected to the curtain hook. When the curtain rod is bent, the fixing component and curtain hook are disassembled, and the timing belt is cut off, preventing it from being stretched during bending. This improves the ease of transportation after assembly and facilitates rapid assembly at the installation point. Furthermore, the folded curtain rod is easy to store.

[0009] When in use after installation, the curtain rod is threaded through several pre-made curtain rings on the curtain. One of the curtain rings is engaged with the curtain hook. The drive unit drives the timing belt to move, the timing unit drives the curtain hook to move, and the curtain hook drives the curtain ring to move the curtain up and down.

[0010] Optionally, the curtain rod has a main sliding channel, a main directional channel, and a main clearance channel connecting the main sliding channel and the main directional channel. The main sliding channel is for the curtain hook to engage and slide, the main directional channel is for the timing belt to move, the timing element engages and slides in the main directional channel, and the timing element has a connecting part for insertion into the curtain hook. The connecting part engages and slides in the main clearance channel.

[0011] By adopting the above technical solution, the connecting part is inserted into the curtain hook. While the main sliding channel is connected to the sliding of the curtain hook, it also plays a limiting role for the curtain hook, so that the curtain hook only slides along the length of the curtain rod.

[0012] The main channel allows the timing belt to pass through and move, while simultaneously sliding and connecting with the timing component, limiting the timing component so that it slides only along the length of the curtain rod. The cooperation between the timing component and the main channel improves the smoothness of the timing belt's movement. Thus, when the drive component moves the timing belt, the timing belt drives the timing component to slide, and the timing component drives the curtain hook to slide through the connecting component.

[0013] Optionally, the timing belt has a plurality of toothed blocks, the timing component includes a belt buckle seat, the connecting part is fixedly disposed in the belt buckle seat, the belt buckle seat has a groove for the cut end to be inserted, and the groove wall of the groove has a toothed slot for the toothed block to be engaged.

[0014] By adopting the above technical solution, the timing belt is embedded in the groove, and the toothed block is engaged in the corresponding toothed groove. When the timing belt moves, it can drive the belt buckle seat to slide, thereby realizing the linkage between the timing component and the timing belt.

[0015] Optionally, the synchronizing element further includes a buckle cover for covering the groove, the buckle cover having a limiting rod, the buckle seat having a limiting groove that cooperates with the limiting rod, the groove wall of the groove having a locking hole, and the buckle cover having a buckle that cooperates with the locking hole.

[0016] By adopting the above technical solution, the limiting rod is inserted into the limiting groove, and the buckle is inserted into the groove and engaged with the buckle hole to fix the buckle cover and the buckle seat.

[0017] At the same time, the buckle cover covers the opening of the groove, which can prevent the timing belt from moving out of the groove and realize the fixation of the timing belt and the timing component.

[0018] Optionally, the curtain hook includes a trolley that is engaged and slides in the main sliding channel, a clamping frame disposed on the trolley, and a movable clip disposed on the clamping frame. The clamping frame is provided with a fixed clip corresponding to the movable clip, and a limiting structure for restricting the sliding of the movable clip is provided between the clamping frame and the movable clip.

[0019] By adopting the above technical solution, the trolley slides along the length of the curtain rod through the main sliding channel, placing the curtain ring in the clamping frame and between the movable clip and the fixed clip. The movable clip slides so that it abuts against one side of the curtain ring and the other side of the curtain ring abuts against the fixed clip. The sliding of the movable clip is restricted by the limiting structure, so that the curtain ring is fixed between the movable clip and the fixed clip, and the sliding of the curtain hook can drive the opening and closing of the curtain.

[0020] Optionally, the limiting structure includes an elastic part disposed on the movable clamp, and a plurality of stop blocks disposed on the elastic part and the clamping frame, wherein two adjacent stop blocks form a stop groove for the corresponding stop block to be engaged.

[0021] By adopting the above technical solution, the stop block on the clamping frame is engaged in the stop groove on the elastic part, and at the same time, the stop block on the elastic part is engaged in the stop groove on the clamping frame, thereby restricting the slippage of the movable clip. Furthermore, there are several stop blocks on both the clamping frame and the elastic part, which can adjust the distance between the movable clip and the fixed clip to suit curtain rings of different sizes and thicknesses.

[0022] When adjustment is needed, the elastic part is rotated away from the clamping frame, the elastic part undergoes elastic deformation, the movable clamp slides to the required position, and the stop block aligns with the corresponding stop groove. The elastic part then elastically resets and rotates towards the clamping frame to achieve automatic positioning after the movable clamp slides.

[0023] Optionally, the elastic part is provided with an operating handle, and the movable clamp is provided with a relief groove corresponding to the operating handle.

[0024] By adopting the above technical solution, pressing the operating handle causes it to move into the clearance groove, which facilitates the rotation of the elastic part away from the clamping frame, thus achieving the effects of saving effort and convenient operation.

[0025] Optionally, the trolley is provided with a fixing groove, the clamping frame is provided with a fixing part that is engaged and slides in the fixing groove, the groove wall of the fixing groove is provided with a first stop block, and the fixing part is provided with a second stop block that cooperates with the first stop block.

[0026] By adopting the above technical solution, the fixing part is inserted into and slides in the fixing groove. The first stop and the second stop abut one side, causing the fixing part to elastically deform and rotate in the direction away from the second stop. After the first stop passes the second stop, the fixing part elastically resets, causing the first stop and the second stop to abut the other side, so as to restrict the fixing part from sliding out of the fixing groove and to fix the clamp and the trolley.

[0027] Optionally, the trolley is provided with a slot, and the clamping frame is provided with a plug corresponding to the slot, the plug being provided with reinforcing ribs.

[0028] By adopting the above technical solution, the insert block is inserted into the slot, and the reinforcing rib abuts against the slot wall, causing the reinforcing rib to undergo elastic deformation. Since the reinforcing rib maintains the tendency of elastic recovery, the interference fit between the insert block and the slot is achieved, improving the firmness of the clamping frame and the trolley.

[0029] Optionally, the connector has mounting portions on both sides facing each other, the guide rail has a connecting groove that is interference-fitted with the mounting portion, and the connector has a secondary sliding channel corresponding to the main sliding channel, a secondary guide channel corresponding to the main guiding channel, and a secondary clearance channel corresponding to the main clearance channel.

[0030] By adopting the above technical solution, the two guide rails are connected by a connector, and the mounting part is inserted into the corresponding connecting groove. During this process, the mounting part undergoes elastic deformation and maintains a tendency to elastically return to its original position, thereby achieving an interference fit between the mounting part and the connecting groove. At the same time, a certain force can be applied to move the mounting part out of the connecting groove, which facilitates the quick installation and disassembly of the two guide rails and improves convenience.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. Divide a curtain rod into multiple guide rails. Each pair of guide rails can be detachably connected by connectors. Before transportation, disassemble and bend the two guide rails, remove the fasteners and curtain hooks, and cut the timing belt to prevent the timing belt from being stretched during the bending of the curtain rod. This improves the convenience of transporting the assembled curtain rod and facilitates quick assembly after transportation to the installation point.

[0033] 2. The stop block on the clamping frame is engaged in the stop groove on the elastic part, and at the same time, the stop block on the elastic part is engaged in the stop groove on the clamping frame, thereby restricting the sliding of the movable clip. There are several stop blocks on both the clamping frame and the elastic part, which can adjust the distance between the movable clip and the fixed clip to suit curtain rings of different sizes and thicknesses.

[0034] 3. When adjustment is required, the elastic part is rotated away from the clamping frame, the elastic part undergoes elastic deformation, the movable clamp slides to the required position, and the stop block aligns with the corresponding stop groove. The elastic part elastically resets and rotates towards the clamping frame to achieve automatic positioning after the movable clamp slides.

[0035] 4. Two guide rails allow for quick installation and removal, improving convenience. Attached Figure Description

The opposing side walls of the secondary sliding channel 42 are integrally formed with guide strips 115.

[0055] The implementation principle of an electric curtain track according to an embodiment of this application is as follows:

[0056] A curtain rod 1 is divided into multiple guide rails 11, with each pair of guide rails 11 detachably connected by a connector 4. Before transportation, the two guide rails 11 are disassembled and bent. Since the timing belt 31 will be tightened during the bending of the curtain rod 1, it is easy to cause the two guide rails 11 to be unable to bend. Therefore, the timing belt 31 is made into a cut-off type, with the cut end 311 fixed to the timing component 12. The fixing component is detachably connected to the curtain hook 2. When the curtain rod 1 is bent, the fixing component and the curtain hook 2 are disassembled, and the timing belt 31 is cut off to prevent the timing belt 31 from being tightened during the bending of the curtain rod 1. This improves the convenience of transporting the curtain rod 1 after assembly and also facilitates quick assembly after transportation to the installation point.

[0057] When in use after installation, the curtain rod 1 is threaded through several pre-made curtain rings on the curtain. One of the curtain rings is engaged with the curtain hook 2. The drive component 32 drives the synchronous belt 31 to move, the synchronous component 12 drives the curtain hook 2 to move, and the curtain hook 2 drives the curtain ring to move the curtain up and down.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
