Description

Technical Field

[0001] This utility model belongs to the field of electric curtain technology, and specifically relates to a silent structure for electric curtain tracks. Background Technology

[0002] With the popularization of smart home technology, motorized curtains, as an important product for improving the convenience of life, have seen their market growth rate increase year by year. Existing motorized curtain tracks usually use a motor to directly drive a slider through gears, chains, or belts, and drive the curtains to open and close based on automated control, which realizes the convenience of life. However, excessive mechanical contact transmission makes the curtains noisy during the opening and closing process.

[0003] For example, Chinese patent CN218912764U discloses an electric curtain track. The track uses a motor to drive a ring belt to move a sliding mechanism horizontally. The positioning structure allows the sliding mechanism to overcome the positioning force to complete a 90-degree rotation of the blades before moving horizontally in the opposite direction to open the curtain. This achieves precise positioning when the curtain is closed and angle adjustment when it is opened, ensuring that the blades move synchronously and stably and avoiding jamming. However, in this solution, the use of a multi-layer mechanical linkage mechanism increases the probability of failure and the maintenance cost is high. Furthermore, the long-term friction between the ring belt and the transmission wheel is prone to generating high-frequency noise, which is more obvious when running at high speed. When the sliding mechanism passes over the height difference positioning block, it will produce a metallic collision sound. Utility Model Content

[0010] Several hemispherical grooves are evenly formed on the inner wall of the sliding ring, and a ball is embedded in each groove, which is in rolling connection with the groove.

[0011] A further embodiment is that a deflector is provided between the hanging ring and the sliding ring;

[0012] A reversing bearing is embedded in the bottom of the sliding ring. The outer ring of the reversing bearing is interference-fitted with the sliding ring. The top of the reversing rod is interference-fitted with the inner ring of the reversing bearing. The bottom of the reversing rod is fixedly connected to the hanging ring.

[0013] A further option is to coat the outside of the guide rod with a PTFE coating.

[0014] A further embodiment is that the driving mechanism includes a mounting plate, one side of which is fixedly connected to the sliding rail, and a motor is provided on the side of the mounting plate near the sliding rail, with the output shaft of the motor passing through the mounting plate;

[0015] A main pulley and a secondary pulley are provided on the other side of the mounting plate. The main pulley is sleeved on the output shaft of the motor, and the secondary pulley is sleeved on the rotating shaft. The main pulley and the secondary pulley are connected by belt drive.

[0016] A further embodiment is that the driving mechanism includes a gearbox, which is fixedly connected to one side of the sliding track; a motor is provided on the top of the gearbox, and a first helical gear and a second helical gear are provided inside the gearbox, which are respectively rotatably connected to the gearbox.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention features a rotating shaft within a sliding track, with multiple rotating magnets mounted on the shaft. A drive mechanism drives the shaft and magnets to rotate synchronously, creating a continuous, alternating magnetic field distribution. The sliding magnets are pulled by the magnetic field of the rotating magnets and slide along the guide rod under the influence of the magnetic force, thus opening and closing the curtains. The magnetic coupling between the rotating and sliding magnets avoids direct contact between mechanical parts, eliminating frictional noise from traditional gear or chain drives. The design of opposite magnetic poles on the same side of adjacent rotating magnets enhances magnetic field stability and reduces vibration noise caused by magnetic field fluctuations.

[0021] This invention coats the outside of the guide rod with a PTFE coating, which significantly reduces the coefficient of friction between the slider and the guide rod, as well as between the sliding ring and the guide rod, making the sliding smoother. Furthermore, the ball bearing structure on the inner wall of the sliding ring converts sliding friction into rolling friction, further reducing noise and jamming.

[0022] This invention features a telescopic rod between the slider and the sliding magnet, which can adjust the distance between the sliding magnet and the rotating magnet to accommodate different curtain weights and maintain stable magnetic drive.

[0023] The drive mechanism of this utility model adopts two schemes: belt drive and gearbox drive. The belt drive reduces vibration through the elastic buffer of the belt, while the gearbox drive reduces transmission noise through the meshing of helical gears, thus meeting the needs of different scenarios.

[0030] To make the objectives, technical solutions, design methods, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0031] Example 1

[0032] like Figure 1 As shown, this utility model provides a silent structure for an electric curtain track, including a sliding track 1, the back of which is fixedly connected to a wall; a rotating shaft 3 is provided inside the sliding track 1, one end of which is rotatably connected to the inner wall of one end of the sliding track 1, and a driving mechanism is provided at the other end of the sliding track 1 to drive the rotating shaft 3 to rotate; a plurality of rotating magnets 4 are fixedly sleeved on the rotating shaft 3, and the magnetic poles of two adjacent rotating magnets 4 on the same side are opposite. For example, if the bottom of one rotating magnet 4 is the N pole, then the bottom of the adjacent rotating magnet 4 is the S pole, so that the magnetic poles at the bottom of the rotating magnets 4 are arranged in an S, N, S, N pattern. When the rotating shaft 3 and the rotating magnets 4 are driven to rotate synchronously by the driving mechanism, a continuous alternating magnetic field distribution is formed, which enhances the stability of the magnetic field and reduces vibration noise caused by magnetic field fluctuations. A guide rod 9 is parallel to the bottom of the rotating shaft 3, and a PTFE coating is applied to the outside of the guide rod 9. Both ends of the guide rod 9 are connected to the inner wall of the sliding track 1. A slider 7 is slidably mounted on the guide rod 9, and a sliding magnet 5 is mounted on the top of the slider 7, located below the rotating magnet 4. Several hanging rings 8 are also mounted on the guide rod 9 for connecting the curtain 15. Each hanging ring 8 is located on one side of the slider 7, and the bottom of the slider 7 is connected to the top of the curtain 15. When the drive mechanism drives the rotating shaft 3 and the rotating magnet 4 to rotate synchronously, a moving magnetic field wave is formed. Under the influence of the magnetic field, the sliding magnet 5 is propelled forward by the principle of like poles repelling and unlike poles attracting, thereby opening the curtain 15. When it is necessary to close the curtain 15, the drive mechanism is controlled to rotate in the opposite direction. Similarly, the interaction between the magnetic poles of the rotating magnet 4 and the sliding magnet 5 causes the slider 7 to slide in the opposite direction along the guide rod 9, closing the curtain 15.

[0033] In practical applications, this embodiment takes a single window as an example. There may be a need to hang sheer curtains and cloth curtains. Therefore, a connecting rod 6 is also provided between the slider 7 and the sliding magnet 5. One end of the connecting rod 6 is fixedly connected to the top of the slider 7, and the other end of the connecting rod 6 is connected to the bottom of the sliding magnet 5. The connecting rod 6 is a telescopic rod, which can adjust the distance between the sliding magnet and the rotating magnet to adapt to different curtain weights and maintain stable magnetic drive.

[0034] like Figure 2 and Figure 3 As shown, in order to further reduce the friction between the hanging ring 8 and the guide rod 9, in this embodiment, a sliding ring 10 is provided between the hanging ring 8 and the guide rod 9. The sliding ring 10 is sleeved on the guide rod 9, and the hanging ring 8 is located at the bottom of the sliding ring 10. A plurality of hemispherical grooves 11 are evenly formed on the inner wall of the sliding ring 10. A ball bearing 12 is embedded in each groove 11. The ball bearing 12 is in rolling connection with the groove 11, which converts sliding friction into rolling friction, further reducing noise and jamming. Because the curtain 15 rotates longitudinally at a certain angle during opening and closing, increasing the friction between the sliding ring 10 and the guide rod 9, a deflector rod 14 is provided between the hanging ring 8 and the sliding ring 10 in this embodiment. Specifically, a deflector bearing 13 is embedded in the bottom of the sliding ring 10, with its outer ring interference-fitted to the sliding ring 10, its top co-fitted to the inner ring of the deflector rod 14, and its bottom fixedly connected to the hanging ring 8. During the opening and closing of the curtain 15, the deflector rod 14 rotates, preventing the sliding ring 10 from rotating and ensuring its stability.

[0035] Continue to refer to Figure 2 In this embodiment, the drive mechanism includes a mounting plate 2, one side of which is fixedly connected to the sliding rail 1, and a motor 16 is provided on the side of the mounting plate 2 near the sliding rail 1, with the output shaft of the motor 16 passing through the mounting plate 2; a main pulley 17 and a secondary pulley 18 are provided on the other side of the mounting plate 2, the main pulley 17 is sleeved on the output shaft of the motor 16, and the secondary pulley 18 is sleeved on the rotating shaft 3; the main pulley 17 and the secondary pulley 18 are connected by a belt 19, and the belt elastically buffers and reduces vibration.

[0036] Example 2

[0037] Based on Example 1, in order to adapt to different installation and usage scenarios, the following can also be adopted: Figure 4 The drive mechanism shown specifically includes a gearbox 20, which is fixedly connected to one side of the sliding track 1. A motor 16 is installed on the top of the gearbox 20. A first helical gear 21 and a second helical gear 22 are installed inside the gearbox 20, and the first helical gear 21 and the second helical gear 22 are rotatably connected to the gearbox 20. The first helical gear 21 is arranged horizontally and connected to the output shaft of the motor 16. The second helical gear 22 is arranged vertically and sleeved on the rotating shaft 3. The first helical gear 21 and the second helical gear 22 are meshed together, and the gearbox transmission effectively reduces transmission noise through the meshing of the helical gears.
