[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Most electric curtain tracks and pulleys on the market do not have self-lubricating function. Although they can provide a smooth sliding experience in the initial use, friction and wear problems gradually appear as the usage time goes on. It is easy for them to slide poorly or even get stuck, which seriously affects the smooth operation of the curtains. They also need to be manually lubricated regularly, which not only affects the service life of the curtains, but also affects the user experience.

[0022] To address the aforementioned defects in curtain tracks during long-term use, please refer to [link / reference]. Figures 1-4This utility model provides an electric curtain track and pulley assembly structure that achieves a self-lubricating effect on the guide rails and rollers each time the curtains are opened and closed, ensuring smooth opening and closing of the curtains. The structure is based on a track body 1 and a pulley assembly 2. A pair of guide rails 101 are installed inside the track body 1. The pulley assembly 2 includes a moving shaft 201 located inside the track body 1. Rollers 202, adapted to the guide rails 101, are rotatably mounted at both ends of the moving shaft 201. A housing 203 is fixedly fitted in the middle of the moving shaft 201, and a hook 204 is fixedly connected to the lower end of the housing 203. The hook 204 is used to hang the curtains. The user electrically controls the sliding of the housing 203 (this is prior art and will not be described in detail here). The sliding of the housing 203 drives the rollers 202 to roll via the moving shaft 201. The rolling of the rollers 202 assists the sliding of the moving shaft 201, realizing the retraction and unfolding of the curtains. During the curtain's retraction and expansion, to ensure the smooth rolling of the rollers 202 and avoid excessive friction between the rollers 202 and the guide rail 101, lubrication mechanisms 3 are provided on both sides of the top of the guide rail 101. These lubrication mechanisms 3 lubricate the guide rail 101, thereby reducing friction between the guide rail 101 and the rollers 202. An oil box 301 is fixedly installed on the top of the guide rail 101, containing lubricating oil. A strip-shaped oil outlet 302 is provided on one side of the oil box 301, and the outer wall of the oil box 301 is slidably connected to seal the oil outlet. The baffle 303 of the oil outlet 302 and the oil box 301 are also equipped with an oil control component 304 to drive the baffle 303 to slide up and down. Whenever the roller 202 rolls to the oil control component 304, it can trigger the oil control component 304 to drive the baffle 303 to slide upward, opening the oil outlet 302. The lubricant in the oil box 301 can flow out from the oil outlet 302 and flow into the guide rail 101, so that the guide rail 101 can be self-lubricated every time the curtain is opened and closed, preventing wear between the guide rail 101 and the roller 202. It does not require frequent maintenance by the user, is convenient to use, and extends the service life of the equipment.

[0023] To achieve the control effect of the oil control component 304 on the baffle 303, a gear 3041 is rotatably mounted on the side of the oil box 301, and a rack 3042 is fixedly mounted on the top of the baffle 303. The rack 3042 meshes with the gear 3041. A groove 3043 is also provided on the side of the oil box 301. A rack 3044 that meshes with the gear 3041 is slidably connected inside the groove 3043. One end of the rack 3044 is fixedly connected to a pressing rod 3045, and the other end is fixedly connected to a connecting spring 3046. The inclination angle of the connecting spring 3046 matches the rolling trajectory of the roller 202. The end of the connecting spring 3046 is fixedly mounted on the inner wall of the groove 3043. When the roller 202... 02 Rolls to the end of the track body 1. Its inertia can impact the extrusion rod 3045, causing rack 2 3044 to slide along the inclined groove 3043. At this time, the connecting spring 3046 deforms, and rack 2 3044 drives gear 3041 to rotate counterclockwise. The rotation of gear 3041 drives rack 1 3042 to slide upward. Then rack 1 3042 drives baffle 303 to slide upward, and the oil outlet 302 can be opened instantly, allowing a small amount of lubricating oil to flow out. Subsequently, rack 2 3044 slides back to its original position by the elastic force of connecting spring 3046. Similarly, it drives baffle 303 to slide back to its original position, resealing the oil outlet 302. This setting of instantaneous opening of baffle 303 can prevent excessive loss of lubricating oil, save resources, and achieve reasonable lubrication.

[0024] In order to allow the lubricating oil to flow smoothly into the guide rail 101, a guide platform 305 with a triangular cross-section is fixedly connected to the bottom of the oil box 301 near the oil outlet 302. The guide platform 305 is located below the oil outlet 302, and the lubricating oil can enter the guide rail 101 along the guide platform 305.

[0025] When the lubricating oil in the oil box 301 is used up, it needs to be replenished. Therefore, an oil filling hole 306 is provided at one end of the oil box 301, and a sealing plug for sealing the oil filling hole 306 is installed on the oil box 301. The lubricating oil can be replenished by opening the sealing plug.

[0026] In order to ensure the smooth sliding of the cover 203, its movement needs to be guided. Therefore, ball bearings 205 are installed on both sides of the cover 203, and roller grooves 102 for the ball bearings 205 to roll are opened on both sides of the inside of the track body 1. The setting of the ball bearings 205 can guide its movement while ensuring its smoothness and not affecting the smoothness of the opening and closing of the curtain.

[0027] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0028] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
