Description

Technical Field

[0001] This application relates to the field of curtains, and in particular to a non-standard curtain that can automatically rise and fall. Background Technology

[0002] As people's living standards continue to improve, their demands for comfort and personalization in their living environments are increasing. Curtains, as an important component of interior decoration and sun shading, are also constantly evolving. Among them, irregularly shaped windows are widely used in villas, duplexes, and some commercial buildings due to their unique shapes and aesthetic appeal. However, traditional curtain structures are mostly suitable for regular window shapes. When faced with irregularly shaped windows (such as arched, trapezoidal, and irregular polygonal shapes), they often struggle to achieve a good fit and light-blocking effect, resulting in problems such as poor aesthetics, complex installation, and inconvenient operation.

[0003] Especially for irregularly shaped windows that are high up or difficult to reach, manually opening and closing curtains poses certain safety hazards, is inconvenient to use, and cannot achieve intelligent control. While some existing automatic curtain products can achieve lifting and lowering control, most are still limited to ordinary straight curtains and lack the ability to adapt to irregularly shaped windows. Their structures are either unsuitable or their control methods are unstable, failing to guarantee a good user experience. Furthermore, existing automatic curtains still have room for improvement in terms of curtain body connection structure, lifting system, and durability. Issues such as the inability of curtain slats to fold and overlap effectively, curtain cord slippage, and easily damaged transmission components all limit their widespread application.

[0004] Therefore, there is an urgent need to propose a non-standard curtain structure that is structurally sound, stable in operation, highly adaptable, and capable of automatic lifting, in order to meet the actual needs of modern architecture in the development of diverse window decorations and smart homes. Utility Model Content

[0007] By adopting the above technical solution, precise control and automatic lifting / lowering of irregularly shaped curtains are achieved. Two motors are installed inside the curtain frame to drive the curtain cords to coil synchronously, thereby causing the curtain body to orderly retract vertically towards the lower end of the frame. This solves the problem of traditional irregularly shaped curtains being unable to achieve automated control. It is not only suitable for irregularly shaped windows of various shapes but also ensures smooth, synchronous, and neat retraction during the curtain's lifting and lowering process, effectively avoiding jamming and tilting caused by unreasonable structures. The combination of motor drive and curtain cord pulling design enhances the system's stability and operational precision, improving the user experience. Furthermore, this technical solution lays a solid foundation for intelligent curtain control, possessing the potential to be further expanded into remote or sensor-based control.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0027] This application discloses an irregularly shaped curtain that can automatically rise and fall. (See also...) Figure 1 , Figure 2 , The automatic lifting irregular-shaped curtain includes an irregular-shaped curtain body 100, which includes a curtain frame 10 and a curtain body 20. The curtain frame 10 is the main structural frame for supporting and installing power transmission components. The curtain body 20 is installed at the lower end of the curtain frame 10. The curtain frame 10 is equipped with a motor 103 and a motor 1031, both of which are small DC motors. They are driven by synchronous or individual control. The motor 103 and the motor 1031 control the curtain cord 50 to wind in an orderly manner, so that the curtain cord 50 generates a traction force on the curtain body 20, thereby causing the curtain body 20 to gradually retract towards the lower part of the curtain frame 10, thus realizing the automatic lifting and lowering operation of the curtain.

[0028] The main curtain body 20 consists of two parts: an upper irregularly shaped curtain 30 and a lower curtain 40. The irregularly shaped curtain 30 is fixedly connected to the curtain 40 via a connecting structure, allowing the entire curtain to hang vertically. The irregularly shaped curtain 30 is composed of several slats 201 strung together. The size and shape of these slats 201 are designed according to the actual irregular window outline, and all are of uniform size to facilitate neat overlapping and folding. The curtain 40 is a more conventionally shaped curtain section, composed of several slats 202 strung together. The slats 202 are also of uniform size, facilitating overlapping and folding during folding. To ensure stable guidance and durable use, both slat 1 201 and slat 202 have through holes on their left and right sides for the cord 50 to pass through. The cord 50 is a single cord, with one end of the cord 50 wound and connected to a winding wheel 104 on one side. The other end of the cord 50 passes downwards through the through holes on one side of slat 1 201 of the irregular curtain 30, and then extends horizontally to the other side at the bottom of the bottom slat 202. After passing upwards through several through holes of slat 202 and slat 1 201 from the other side of slat 202, it is wound and connected to the winding wheel 104 on the other side.

[0029] The curtain frame 10 is composed of a curtain frame 101. The curtain frame 101 has a cavity structure inside, namely the inner cavity 102. Motor 103 and Motor 2 1031 are installed inside the inner cavity 102 to output power in a concealed manner, effectively reducing space occupation and improving the degree of structural integration. Motor 103 and Motor 2 1031 are electrically connected to an external power source through wires, and can be connected to mains power or connected to an intelligent control circuit board system, such as a remote control, timer or sensor components, etc., and have good intelligent expansion capabilities.

[0030] The rotating shafts of motor 103 and motor 21031 are respectively equipped with transmission gear assemblies 105. The transmission gear assembly 105 includes two meshing helical gears. One helical gear is fixedly connected to the rotating shaft of bearing housing 106, and the other is connected to the output shaft of the motor. The torque is transmitted between the two through helical gear transmission. When the motor starts, it drives the rotating shaft to rotate, thereby causing the winding wheel 104 installed on the rotating shaft to rotate synchronously, completing the winding or unwinding operation of the curtain 50, and realizing the raising and lowering movement of the curtain.

[0031] To address the friction issue during the lifting process, an anti-slip textured structure is provided on the surface of the winding wheel 104. This structure can be in the form of spiral protrusions, grid patterns, or striped grooves to increase the friction between the cord 50 and the winding wheel 104, effectively preventing the cord from slipping or loosening during the lifting process and improving overall stability.

[0032] Wear-resistant bushings are installed inside the through holes of slat 1 201 and slat 2 202. The bushing material can be made of materials with wear-resistant and low-friction properties such as polytetrafluoroethylene, nylon, and brass. This can significantly reduce the wear of the cord 50 during long-term operation, protect the slats from being cut or torn, extend the overall product life, and improve the reliability of use.

[0033] To enhance the strength and environmental resistance of the curtain frame structure, the curtain frame 101 is preferably made of aluminum alloy. Aluminum alloy has the characteristics of high strength, light weight and good corrosion resistance, making it suitable for long-term use in indoor and outdoor environments. At the same time, to further improve its corrosion resistance, the outer surface of the curtain frame 101 is covered with an anti-corrosion coating, which can be achieved by epoxy powder coating, electrophoretic paint or fluorocarbon spraying, etc. This not only extends the service life, but also improves the appearance and aesthetics.

[0034] To meet the dual requirements of strength and flexibility of the curtain cord during automatic lifting, the curtain cord 50 is made of braided steel wire rope or high-strength nylon rope. Braided steel wire rope has extremely high load-bearing capacity and is suitable for large-size or heavy-duty curtain structures; high-strength nylon rope has good flexibility and fatigue resistance and is suitable for environments with high comfort requirements such as homes and hotels. Both can be selected as needed.

[0035] In practical implementation, the automatic lifting irregular-shaped curtain of this application controls the start, stop and forward and reverse rotation of motor 103 and motor 2031 to realize the raising and lowering of the curtain cord 50, thereby driving the curtain body 20 to rise or fall. In the closed state, the curtain slats 101 and 202 overlap and fold in sequence, neatly gathered, with a compact overall volume, without affecting lighting and view. In the unfolded state, the curtain hangs flat, matching the shape of the irregular window, and has a good decorative effect and light-blocking function.

[0036] In addition, the curtain system has a good control expansion interface and can reserve an interface for intelligent control circuit modules, which can facilitate the subsequent integration of remote controllers, infrared sensors, intelligent voice systems, etc., so as to realize convenient operation and automated management of curtains by users.

[0037] The implementation principle of an automatically raising and lowering irregular-shaped curtain according to an embodiment of this application is as follows: the curtain cord is controlled by a motor drive system located inside the curtain frame, thereby realizing the automatic raising and lowering operation of the curtain structure. This structure is not only suitable for conventional windows, but also particularly suitable for the shading and aesthetic needs of irregular-shaped windows, and has significant advantages in terms of ease of use, structural stability and intelligence. The curtain frame is the supporting foundation of the entire curtain system, and two motors are embedded inside it. The motors adopt a DC drive method and can work independently or in concert. According to the actual use needs, they drive the curtain cord to wind or release. The curtain cord completes the power conversion through the winding wheel inside the curtain frame. The winding wheel is connected to the motor output shaft through a set of helical gear transmission components. After the motor starts, it drives the winding wheel to rotate, thereby pulling the curtain cord to close or release, thus realizing the closing or releasing of the curtain.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
