Description

Technical Field

[0001] This utility model relates to the field of curtain track technology, specifically a serpentine curtain cross trolley. Background Technology

[0002] In the fields of architectural decoration and interior lighting control, serpentine blinds are widely used due to their aesthetic appeal and excellent light-blocking effect. Especially in scenarios with high light-blocking requirements, such as bedrooms and home theaters, the alignment of the two blind panels directly affects the overall light-blocking performance. However, existing serpentine blind trolley systems are insufficient to meet the demands for efficient light-blocking.

[0003] Most serpentine blind slats on the market currently use a conventional parallel joining method, where the two blinds only meet at the edges when closed. This joining method prevents the two blinds from overlapping, resulting in noticeable gaps. When outside light shines, it easily enters the room through these gaps, severely affecting the light-blocking effect and failing to create a completely dark indoor environment for the user. For example, in the morning when the sun is strong, even if the blinds are closed, the light seeping through the gaps can still affect sleep quality; when watching movies in a home theater, light leakage can also interfere with the viewing experience.

[0004] Furthermore, the structural limitations of traditional serpentine blind sleds result in insufficient fit between the sled and the blind during opening and closing, causing the blind to shift and further widening the gaps at the joints. Simultaneously, due to the lack of optimized design for light-blocking effects, even though some products attempt to improve light blocking by increasing the overlapping area of ​​the blinds, the fundamental problem of the blinds not being able to interlock properly remains unresolved, failing to meet users' demands for high-quality light-blocking performance.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Example 1: As Figures 1-4 ,include: The track 100 has a controller 200 that is plugged into the inner walls of both ends of the track 100. The bottom inner wall of the track 100 has a groove 110. The inner wall of the controller 200 is fixedly installed with a servo motor 220 for raising and lowering the curtain. The trolley assembly includes a first trolley and a second trolley. A cross trolley is provided at the joint of the two sets of trolleys in the middle. The cross trolley includes a Z-shaped cross shaft 360. The two sets of Z-shaped cross shafts 360 can be cross-joined. Hooks are rotatably connected to the bottom of the first trolley, the bottom of the second trolley, and the bottom of the Z-shaped cross shaft 360.

[0020] The specific application scenario of this embodiment is as follows: The track 100 serves as the basic frame of the serpentine curtain cross trolley, and the controller 200 is fixed to its inner walls at both ends by plugging in, providing installation space for the servo motor 220; the bottom slide 110 provides a guide track for the movement of the trolley assembly, and the servo motor 220 serves as a power source to drive the opening and closing of the curtain. In the trolley assembly, the first trolley, the second trolley, and the cross trolley constitute the transmission body. The Z-shaped cross shaft 360 of the cross trolley is designed as two sets of cross-connectable structures. When the trolley moves on the track, the Z-shaped cross shaft 360 can flexibly adjust its angle to ensure a smooth transition and connection between adjacent trolleys; and the hook rotatably connected to the bottom of the trolley can be used to hang the curtain fabric. As the trolley slides on the track, it drives the curtain to open and close, and the rotation characteristics of the hook can adapt to the serpentine staggered hanging shape of the curtain, ensuring that the curtain remains neat and beautiful during movement.

[0021] Example 2: Figures 1-3 The controller 200 has a sleeve 210 on the outer wall of its front end. The sleeve 210 is connected to the outer wall of the end of the track 100 by insertion.

The servo motor 220 installed on the top inner wall drives the take-up wheel 230 to rotate through the output shaft, forming the core of the power transmission system. When the curtains need to be opened or closed, the servo motor 220 rotates forward or reverse according to the set program, and the take-up wheel 230 winds up or releases the traction rope accordingly. The traction rope is connected to the first traction block 340 and the second traction block 450 of the trolley assembly, pulling the trolley to move in the slide groove 110 of the track 100, thereby realizing the automatic opening and closing of the curtains. The design of the sleeve rod 210 ensures the stable cooperation between the servo motor 220 and the track 100, making the power transmission more stable and reliable, and avoiding the problem of curtains not opening and closing smoothly due to loose connection.

[0023] Example 3: Figure 4and Figure 5 The first trolley includes a first slide block 300. The inner walls of both sides of the first slide block 300 are rotatably connected to first rollers 310 via pivot pins. A first retaining seat 320 is fixedly installed on the bottom outer wall of the first slide block 300. The inner wall of the first retaining seat 320 is rotatably connected to a first hook 330.

The bottom inner wall of the second retaining seat 420 is rotatably connected to a second hook 430. A Z-shaped hook is fixedly connected to the outer wall of the second retaining seat 420 on the side furthest from the first slide block 300. A Z-shaped cross shaft 360 is fixedly installed on the bottom outer wall of the Z-shaped cross shaft 360. A third hook 462 is rotatably connected to the bottom inner wall of the third hook 461. The first hook 330, the second hook 430, and the third hook 462 are used to hang the curtain fabric. The curtain fabric is hung in a serpentine alternating staggered manner. The first roller 310 and the second roller 410 are in rolling contact with the inner wall of the track 100. A first traction block 340 is fixedly installed on the top outer wall of the first slide 300. A second traction block 450 is fixedly installed on the side wall of the second slide. A traction rope is fixedly connected between the first traction block 340 and the second traction block 450. The traction rope is wound around the take-up wheel 230 to control the automatic opening and closing of the curtain fabric.

[0024] The specific application scenario of this embodiment is as follows: The first rollers 310 on both sides of the first slide seat 200 of the first trolley roll in contact with the inner wall of the track 100, which can reduce sliding friction and allow the first trolley to move flexibly within the slide groove 110; the first card seat 320 is rotatably connected to the first hook 330, which facilitates hanging the curtain fabric and adapts to the serpentine shape of the curtain during movement; the structure of the second trolley is similar to that of the first trolley, and the two second trolleys are rotatably connected to the first card seat 320 through ear hooks to form a movable connection structure, ensuring that the trolley assembly can flexibly adjust its posture when turning or changing direction; the Z-shaped cross shaft 360 is connected to the outer wall of the second card seat 320, and its bottom third card seat 461 and The third hook 462 further increases the hanging points of the curtain fabric.

Moreover, the linkage structure between the trolley assemblies and the hook design ensure that the curtain always maintains a stable serpentine shape during the opening and closing process, improving the use effect and aesthetics.

[0025] The working principle of this utility model is as follows: When used by those skilled in the art, the serpentine curtain cross trolley uses the track 100 as the basic frame, and the two ends are fixed with servo motors 220 by controllers 200 through plug-in sleeve rods 210. The output shaft of the servo motor drives the take-up wheel 230 to rotate, providing power to the system. The slide groove 110 at the bottom of the track 100 serves as a guide for the movement of the trolley assembly. The first trolley and the second trolley roll in contact with the inner wall of the track through the first roller 310 and the second roller 310, reducing friction and achieving flexible sliding. The card seats at the bottom of the first slide block 200 and the second slide block 320 are rotatably connected to the first hook 330 and the second hook 430, respectively. The third card seat 461 at the bottom of the Z-shaped cross shaft 360 cooperates with the third hook 462, so that the curtain fabric can be hung in a serpentine alternating staggered manner. The two sets of Z-shaped cross shafts 360 in the middle cross trolley can be cross-connected to ensure a smooth transition and connection when the trolley moves. At the same time, it can prevent gaps from forming between the curtains on both sides when the curtains are closed, thus improving the light-blocking effect and aesthetics of the curtains. During operation, the servo motor 220 drives the take-up wheel 230 to take in and release the traction rope. The traction rope pulls the trolley assembly along the track through the first traction block 340 and the second traction block 450, causing the curtains on the hooks to open and close synchronously. The rotation characteristics of the hooks and the linkage structure between the trolley assemblies ensure that the curtains always maintain a neat and beautiful serpentine shape during the movement, realizing the automatic opening and closing and stable operation of the curtains.
