Description

Technical Field

[0001] This utility model relates to the field of smart home, and in particular to a self-lubricating electric curtain. Background Technology

[0002] In modern home and office environments, motorized curtains are widely used due to their ease of operation and smooth running. Their smooth operation and ease of maintenance directly impact the user experience and the lifespan of the equipment. With increasing user demands, the lubrication and maintenance issues of traditional motorized curtains are becoming increasingly prominent.

[0003] Traditional motorized blinds have significant drawbacks: they control only a single drive mechanism, resulting in concentrated driving force and limited coverage. They can only achieve overall opening and closing, lacking the flexibility to adjust the opening and closing positions of different areas based on lighting needs. This limited functionality makes them unsuitable for diverse usage scenarios. Furthermore, the wheels of the drive carriage are prone to wear due to long-term friction with the guide rails, requiring regular manual lubrication. This cumbersome maintenance process can lead to operational stalls and increased noise due to insufficient lubrication. Prolonged friction and inadequate lubrication accelerate component aging, significantly shortening the lifespan of the motorized blinds and increasing replacement and maintenance costs. These issues limit the convenience and durability of motorized blinds. Utility Model Content

[0004] The purpose of this invention is to provide a self-lubricating electric curtain to solve the problems mentioned in the background art.

[0006] In a preferred embodiment of the present invention, the driving trolley includes a driving body, with movable wheels driven on both sides of the driving body, and movable grooves provided on both sides of the movable groove, with the movable wheels movably disposed within the movable grooves.

[0007] In a preferred embodiment of this utility model, the self-lubricating mechanism includes a rotating connecting frame, with a pair of rotating connecting frames respectively disposed on both sides of the grease tank. An L-shaped pressing member is movably disposed on the rotating connecting frame. A through groove is provided at the bottom of the moving groove, and a pressing block is movably disposed in the through groove. One end of the L-shaped pressing member is connected to the lower part of the pressing block, and a return spring is provided below the same end of the L-shaped pressing member. The other end of the return spring is connected to the bottom of the grease tank. An overflow hole is provided on the side of the moving groove near the driving body, and a squeezing oil suction member is provided in the overflow hole.

[0011] Driven synchronously by several drive carriages within the linear guide rail, the opening and closing positions of different areas of the curtains can be flexibly adjusted according to lighting requirements, meeting the needs of diverse usage scenarios.

[0012] The self-lubricating mechanism drives the trolley's moving wheels to press against the pressure block, which in turn squeezes out lubricating grease from the oil suction component. This provides real-time lubrication to the contact surfaces between the moving wheels and the moving groove, eliminating the need for regular manual lubrication. It avoids jamming and noise caused by untimely lubrication, reduces frictional wear, slows down component aging, and extends service life. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] This utility model provides a technical solution: a self-lubricating electric curtain, such as... Figures 1-3 As shown, it includes a linear guide rail 1, a movable groove 2 inside the linear guide rail 1, several drive trolleys 3 are movably arranged in the movable groove 2, a grease groove 4 is provided below the movable groove 2, and a self-lubricating mechanism 5 is provided in the grease groove 4.

[0021] like Figure 2 , Figure 3 As shown, the driving trolley 3 includes a driving body 301, with movable wheels 302 driven on both sides of the driving body 301, and movable slots 303 on both sides of the movable slot 2, with the movable wheels 302 movably disposed in the movable slots 303.

[0022] like Figure 4 , Figure 5 As shown, the self-lubricating mechanism 5 includes a rotating connecting frame 501. A pair of rotating connecting frames 501 are respectively disposed on both sides of the grease tank 4. An L-shaped pressing member 502 is movably disposed on the rotating connecting frame 501. A through groove 503 is provided at the bottom of the moving groove 303. A pressing block 504 is movably disposed in the through groove 503. One end of the L-shaped pressing member 502 is connected to the lower part of the pressing block 504. A return spring 505 is provided below the same end of the L-shaped pressing member 502. The other end of the return spring 505 is connected to the bottom of the grease tank 4. An overflow hole 506 is opened on the side of the moving groove 303 near the driving body 301. A squeeze-type oil suction member 507 is provided in the overflow hole 506. The other end of the L-shaped pressing member 502 extends to one side of the overflow hole 506.

[0023] like Figure 1 , Figure 2 As shown, a connecting groove 6 is provided on one side of the linear guide rail 1, and a rotating part 7 is provided on one side of the drive trolley 3. A connecting rod 8 is rotatably mounted on the rotating part 7, and a curtain hook 9 is rotatably mounted at the bottom of the connecting rod 8.

[0024] like Figure 1 , Figure 2 As shown, both ends of the drive trolley 3 are provided with buffer components 10. The buffer components 10 include a pair of flexible arc plates 1001, both ends of which are connected to the drive trolley 3.

[0025] In practice, the drive system of the drive trolley 3 is activated, and the drive body 301 drives the moving wheels 302 to roll along the moving groove 303. Multiple drive trolleys 3 move synchronously, and the curtains are opened or closed through the connecting rod 8 and the curtain hook 9. During the movement, the rotation structure of the rotating part 7 and the connecting rod 8 can adapt to the angle changes of the curtains and avoid pulling.

[0026] When adjacent drive vehicles 3 approach each other, the flexible arc plates 1001 of the buffer assembly 10 come into contact with each other and absorb the collision energy through elastic deformation to prevent the vehicles from jamming or being damaged.

[0027] When the trolley 3 moves, the moving wheel 302 presses against the top of the pressing block 504, and the pressing block 504 moves downward along the through groove 503, causing the L-shaped pressing member 502 to rotate around the rotating connecting frame 501, and the return spring 505 is compressed. The other end of the L-shaped pressing member 502 swings towards the overflow hole 506, squeezing the oil suction member 507, so that the lubricating grease in the oil suction member is squeezed out through the overflow hole 506 and drips onto the contact surface between the moving wheel 302 and the moving groove 303, achieving real-time lubrication.

[0028] After the moving wheel 302 leaves the pressure block 504, the return spring 505 releases its elasticity, pushing the L-shaped top pressure member 502 to rotate in the opposite direction. The pressure block 504 returns to the bottom surface of the moving groove 303, and the squeeze-type oil suction member 507 restores its deformation and reabsorbs lubricating grease from the grease groove 4 to prepare for the next lubrication.

[0029] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
