Detailed Implementation

[0044] 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.

[0045] Please refer to Figures 1 to 11 This invention provides a curtain push-pull device, including a first roller assembly 1 and a second roller assembly 2. The first roller assembly 1 is detachably connected to the second roller assembly 2. The first roller assembly 1 includes a first roller 11, and the second roller assembly 2 includes a second roller 21. The first roller 11 and the second roller 21 are used to clamp the curtain rod 100 on both sides. The curtain push-pull device also includes a motor 4 for driving the first roller 11 and / or the second roller 21 to rotate, and a power supply device 3 for supplying power to the motor 4. Specifically, the first roller assembly 1 and the second roller assembly 2 can be fixed to the curtain rod 100 by the clamping force of the first roller 11 and the second roller 21 on the curtain rod 100. The first roller 11 and the second roller 21 can clamp the curtain rod 100 from both vertical and horizontal directions; they can also clamp it from the left and right directions or other directions, and the clamping force is sufficient to overcome the weight of the first roller assembly 1 and the second roller assembly 2.

[0046] The usage process of this solution is as follows: When it is necessary to upgrade traditional curtains to electric curtains, simply assemble the first roller assembly 1 and the second roller assembly 2 together, as follows: Figure 2 As shown ( Figure 2 (The arrows in the diagram indicate the assembly direction of each part). Simultaneously, the first roller 11 and the second roller 21 roll and clamp the curtain rod 100 on both sides. This curtain push-pull device 300 can be installed on the curtain rod 100 between the last hanging ring 200 and the second-to-last hanging ring 200. In use, starting the motor 4 to rotate forward or reverse will cause the curtain push-pull device 300 to reciprocate along the curtain rod 100 (e.g., ...). Figure 1 (The direction of movement is indicated by the middle arrow), thereby opening or closing the curtain fabric 400 by moving the hanging ring 200.

[0047] It should be noted that the first roller assembly 1 and the second roller assembly 2 in this solution can be arranged in various ways when installed on the curtain rod 100. For example, both roller assemblies can be arranged on one side of the curtain rod 100, or the two roller assemblies can surround the curtain rod 100, etc. Preferably, when the first roller assembly 1 and the second roller assembly 2 are assembled, they form a mounting groove around the outer periphery of the curtain rod 100. The first roller 11 and the second roller 21 are located on the upper and lower sides of the curtain rod 100, respectively. Figure 1 and Figure 6 As shown. This arrangement allows for the placement of limiters around the curtain rod 100, thereby preventing the two roller assemblies from accidentally detaching from the curtain rod 100 and improving reliability.

[0048] It should be noted that the aforementioned mounting groove can be designed in various shapes and structures, such as a U-shaped groove, a rectangular groove, a semi-circular groove, or a V-shaped groove, etc. Preferably, the upper end of the first roller assembly 1 is provided with a U-shaped groove 12, and the second roller assembly 2 is detachably connected to the top end face 15 of the first roller assembly 1. The first roller 11 is located at the bottom of the U-shaped groove 12, and the second roller 21 is located at the lower end of the second roller assembly 2, such as... Figure 3 As shown.

[0049] It should be noted that in this solution, the first roller 11 and the second roller 21 can each be set as one or more. Preferably, the bottom of the U-shaped groove 12 is provided with two first rollers 11, and the two first rollers 11 are respectively located on the front and rear sides of the second roller 21 along the length of the curtain rod 100. Figure 5 As shown, the forward and backward directions mentioned in this article refer to the forward and backward directions when the curtain push-pull device drives the hanging ring 200 to move back and forth along the curtain rod 100. This solution sets two first rollers 11 as supports, and sets a second roller 21 above them, staggered from the two first rollers 11, so that the three rollers can form a triangular support on the upper and lower sides of the curtain rod 100, thereby ensuring the smooth operation.

[0050] It should be noted that the first roller assembly 1 and the second roller assembly 2 can be detachably connected and fixed in various ways, such as by bolts, snap-fit ​​connections, hook connections, etc. Preferably, in this solution, the first roller assembly 1 and the second roller assembly 2 are connected by an elastic hook assembly.

[0051] More preferably, the aforementioned elastic hook assembly includes a hook 14 and a hanging hole 26 for preventing the first roller assembly 1 and the second roller assembly 2 from disengaging from each other. The elastic hook assembly also includes an elastic pin 22 and a pin hole 13 for limiting the relative translational movement of the first roller assembly 1 and the second roller assembly 2. Specifically, as shown... Figure 3 and Figure 4 As shown, hook 14 is disposed on the upper end face of the first roller assembly 1, and hanging hole 26 is disposed on the lower end face of the second roller assembly 2 (of course, hook 14 can also be disposed on the lower end face of the second roller assembly 2 and hanging hole 26 can be disposed on the upper end face of the first roller assembly 1, which can also achieve hook connection). The location of hanging hole 26 is generally a plate-like structure, thin-walled structure, shell structure, etc. The inner side of hanging hole 26 has space for hook 14 to move, and the inner end face of hanging hole 26 can be engaged with hook 14. During assembly, hook 14 is inserted into hanging hole 26, and then the first roller assembly 1 and the second roller assembly 2 are moved relative to each other along the insertion direction of hook 14, so that hook 14 is engaged with the inner end face of hanging hole 26. At this time, the first roller assembly 1 and the second roller assembly 2 can be connected together.

[0052] Furthermore, to prevent the hook 14 from sliding out of the hanging hole 26, this design also includes an elastic pin 22 and a pin hole 13 to restrict the relative translational movement of the first roller assembly 1 and the second roller assembly 2. Specifically, this design places the elastic pin 22 on the second roller assembly 2 and the pin hole 13 on the upper end face of the first roller assembly 1 (of course, the invention can also place the elastic pin 22 on the first roller assembly 1 and the pin hole 13 on the second roller assembly 2). The lower end face of the second roller assembly 2 is provided with a hole for the elastic pin 22 to extend and retract. The inner side of the second roller assembly 2 is provided with a pin spring 24 that acts on the elastic pin 22. The pin spring 24 drives the elastic pin 22 to extend out of the lower end face of the second roller assembly 2. The elastic pin 22 is also fixedly connected to a pin push rod 23. The pin push rod 23 moves back and forth with the elastic pin 22. The side of the second roller assembly 2 is designed with a push rod sliding hole for the pin push rod 23 to extend and move back and forth. The user can overcome the elastic force of the pin spring 24 and manually push the pin push rod 23 to drive the elastic pin 22 to extend and retract relative to the bottom end face 25 of the second roller assembly 2. Therefore, the assembly process of the curtain push-pull device in this solution is as follows: First, place the second roller assembly 2 and the first roller assembly 1 on the upper and lower sides of the curtain rod 100. Manually push the pin push rod 23 to retract the elastic pin 22 into the interior of the second roller assembly 2. Then, insert the hook 14 of the first roller assembly 1 into the hanging hole 26. Then, move the first roller assembly 1 and the second roller assembly 2 relative to each other along the snapping direction of the hook 14. The hook 14 can be snapped into the end face inside the hanging hole 26. At this time, the elastic pin 22 is aligned with the pin hole 13 below. Manually release the pin push rod 23. The elastic pin 22 then extends into the pin hole 13 under the action of the pin spring 24. The cooperation between the elastic pin 22 and the pin hole 13 can limit the relative translational movement between the first roller assembly 1 and the second roller assembly 2. Therefore, the hook 14 and the hanging hole 26 can maintain the position of mutual snapping, thereby preventing the two roller assemblies from accidentally disengaging.

[0053] Preferably, a clamping space for clamping the curtain rod 100 is formed between the first roller 11 and the second roller 21. The curtain push-pull device of this solution also includes a clamping adjustment mechanism for adjusting the width of the clamping space. This clamping adjustment mechanism allows the two roller assemblies to be adapted to be installed on curtain rods 100 with different diameters and shapes, improving the versatility of the curtain push-pull device.

[0054] It should be noted that the above-mentioned clamping and adjusting mechanism can be designed in various structural forms, such as a screw adjusting mechanism, a pin adjusting mechanism, etc. Preferably, as shown in the figure below. Figure 8 As shown, in this scheme, the motor 4 drives the first roller 11 to rotate, and the clamping adjustment mechanism is disposed on the second roller assembly 2 and is used to adjust the second roller 21 in the width direction along the clamping space (e.g., Figure 8The clamping and adjusting mechanism includes a threaded adjusting nut 27 and an adjusting screw 211, which are located close to or away from the first roller 11 in the direction of the up and down arrows in the image. The second roller 21 is installed at the end of the adjusting screw 211 facing the first roller 11. The adjusting nut 27 is rotatably mounted on the second roller assembly 2 around its own axis. The second roller assembly 2 is provided with a nut displacement limiting structure for limiting the displacement of the adjusting nut 27 relative to the second roller assembly 2 along the rotation axis. The adjusting screw 211 is slidably mounted on the second roller assembly 2 along its own axis. The second roller assembly 2 is provided with a screw rotation limiting structure for limiting the rotation of the adjusting screw 211 relative to the second roller assembly 2 around its own axis. Specifically, the second roller assembly 2 includes an outer housing 20 and an upper cover 29 disposed on the upper end of the housing 20. The nut displacement limiting structure is designed as a ring-shaped nut limiting cover 271, which surrounds the adjusting nut 27 and is fixed to the upper cover 29 of the second roller assembly 2. A limiting space is formed between the nut limiting cover 271 and the upper cover 29 to engage the outer flange of the adjusting nut 27, thereby preventing the adjusting nut 27 from moving axially along the adjusting screw 211. The screw rotation limiting structure is specifically designed as a limiting groove or limiting surface extending axially on the side of the adjusting screw 211. This limiting groove or limiting surface contacts the inner ring of the through hole of the upper cover 29 and restricts the adjusting screw 211 from rotating relative to the second roller assembly 2 about its own axis. By setting up the nut displacement limiting structure and the screw rotation limiting structure, the adjusting screw 211 can be moved up and down along its own axis while the adjusting nut 27 is rotated, thereby driving the second roller 21 to move up and down, so as to adjust the size of the clamping space and adapt to the installation of curtain rods 100 with different diameters.

[0055] Preferably, a vibration-damping elastic element is provided between the adjusting screw 211 and the second roller assembly 2. This vibration-damping elastic element can apply a preload to the adjusting screw 211, which drives the adjusting screw 211 to push the second roller 21 closer to the first roller 11, thereby forming a clamping preload between the first roller 11 and the second roller 21. During the pushing and pulling of the curtain, the vibration-damping elastic element can undergo a certain amount of elastic deformation, ensuring that the first roller 11 and the second roller 21 can roll smoothly on the curtain rod 100, while also playing a vibration-damping role during operation.

[0056] It should be noted that the aforementioned vibration-damping elastic element can be designed in various structural forms, such as springs, elastic pads, and elastic ropes. Preferably, the vibration-damping elastic element in this solution is a vibration-damping spring 28 sleeved on the outer periphery of the adjusting screw 211. One end of the vibration-damping spring 28 acts on the second roller assembly 2, and the other end acts on the adjusting screw 211. Specifically, the upper end of the vibration-damping spring 28 acts on the inner surface of the upper cover 29 of the second roller assembly 2, and the lower end of the vibration-damping spring 28 acts on the spring limiting ring 281 of the adjusting screw 211. Figure 8 As shown.

[0057] Since most curtain rods 100 are circular in cross-section, to ensure the first roller 11 and the second roller 21 can clamp the curtain rod 100 more stably, provide sufficient clamping force for curtain rods 100 with different diameters, and prevent easy wobbling between the curtain rod 100 and the curtain push-pull device, preferably, the second roller assembly 2 includes a roller shaft 212 with two second rollers 21 coaxially rotatably mounted on it. The axis of the roller shaft 212 is parallel to the cross-section of the curtain rod 100, and the distance between the two second rollers 21 is adjustable. This design, by setting two second rollers 21 on the roller shaft 212, ensures that the curtain rod 100 is centered in the clamping space. Furthermore, by adjusting the distance between the two second rollers 21, it ensures that both second rollers 21 can provide sufficient clamping force for curtain rods 100 with different diameters.

[0058] It should be noted that the spacing between the two second rollers 21 on the roller shaft 212 can be adjusted using various adjustment structures, such as a threaded adjustment structure, a pin adjustment structure on the shaft, or a retaining ring adjustment structure. Preferably, this design has a thread on the outer circumference of the roller shaft 212. The second roller 21 includes an inner ring and an outer ring. The inner ring is threadedly engaged with the roller shaft 212, and the outer ring is coaxially rotatably mounted on the outer circumference of the inner ring. After the inner ring is adjusted to the target position, it can be relatively fixed to the roller shaft 212 by threaded locking or pin fixing, thereby determining the spacing between the two second rollers 21. In addition, the outer ring can be designed as a rubber wheel to prevent the second rollers 21 from scratching and abrading the surface of the curtain rod 100.

[0059] Preferably, the first roller 11 has a columnar structure, and its axis is arranged parallel to the cross-section of the curtain rod 100. The outer diameter of the first roller 11 gradually increases from the middle to both ends, such as... Figure 10 and Figure 11 As shown. More preferably, in this design, the middle part of the first roller 11 is designed as a concave central arc segment 111, and both ends of the first roller 11 are designed as cylindrical end segments 112 with cylindrical outer surfaces. This configuration allows the first roller 11 to be suitable for both circular and square curtain rods. That is, the central arc segment 111 can better fit the outer periphery of the circular cross-section curtain rod 100, while the cylindrical end segments 112 can contact and engage with the surface of the square cross-section curtain rod 100, thereby increasing the contact area and friction.

[0060] Preferably, the motor 4 drives the first roller 11 to rotate via a reduction transmission mechanism. Specifically, the reduction transmission mechanism can be a gear reduction transmission mechanism or a worm gear reduction transmission mechanism, etc. Figure 10As shown, this solution preferably uses a worm gear reducer transmission mechanism. While reversing the rotation, it achieves speed reduction and torque increase, providing a sufficiently large driving force to move the heavier curtain fabric 400.

[0061] It should be noted that the power supply device 3 in this solution can be designed as a socket or switch connected to indoor power supply via a power cord, or it can be designed as a battery directly connected to the roller assembly, etc. Preferably, the power supply device 3 in this solution includes a battery disposed in the first roller assembly 1 and / or the second roller assembly 2. Battery power facilitates installation and eliminates the need for wiring.

[0062] It should be noted that the battery can be fixedly connected to the roller assembly or detachably connected. When a fixed connection is used, to ensure the battery has continuous power, this solution can employ a solar cell, allowing it to be charged by sunlight when not in use, thus extending its lifespan. Preferably, the first roller assembly 1 and / or the second roller assembly 2 in this solution are detachably connected to the battery. This detachable connection design facilitates battery replacement and further improves the user experience.

[0063] More preferably, the battery is a rechargeable battery, eliminating the need for users to purchase disposable batteries multiple times, thus reducing user costs.

[0064] Preferably, the motor 4 is connected to the power supply unit 3 via a forward / reverse control module, which in turn communicates with the remote control via a wireless communication module. The forward / reverse control module can be implemented using an existing forward / reverse control switch. This solution, by incorporating a wireless communication module and a remote control, allows the user to remotely control the forward and reverse rotation of the motor 4, thereby enabling the opening and closing of the curtain 400, further simplifying operation and enhancing the user experience.

[0065] It is evident that the present invention has the following beneficial effects:

[0066] 1) The curtain sliding device provided in this solution has a simple structure, is easy to assemble, and is convenient for users to install and operate;

[0067] 2) This solution can upgrade traditional curtains to electric curtains without altering their original structure, making the modification process easy;

[0068] 3) This solution can be battery powered, requires no wiring, and will not damage the wall.

[0069] The present invention also provides an electric curtain including the above-described curtain sliding device 300. This electric curtain has a simple structure, is easy to assemble and maintain, facilitates user installation and operation, and improves the user experience.
