Description

Technical Field

[0001] This invention relates to the field of electric curtains, and more specifically to a linkage-type electric curtain frame and an electric curtain using the same. Background Technology

[0002] With the increasing popularity of smart homes, existing curtain rods for motorized curtains require separate control for each curtain, necessitating two separate power mechanisms. This leads to high implementation costs and makes it difficult to ensure synchronization between the two mechanisms. Furthermore, the length and numerous components of curtain rods make transportation difficult, and installation and maintenance are also quite cumbersome.

[0003] For example, the patent with application number CN202322525612.X, entitled "An Easy-to-Install Electric Curtain," suffers from the aforementioned issues. Similarly, the patent with application number CN202321175387.5, entitled "A Dual-Drive Device for Electric Curtains and an Electric Curtain," while using a communication line to achieve communication transmission and maintain synchronous operation of the first and second drive components, still suffers from the problems of requiring two sets of power mechanisms, resulting in high implementation costs, transportation difficulties, and cumbersome installation and maintenance.

[0004] Therefore, there is an urgent need to design a better electric curtain rod to solve the above-mentioned technical problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a linkage-type electric curtain frame, which uses a single power to realize the automatic opening and closing of two curtains, and has a stable structure, is easy to transport, easy to install on site, and has low operating costs.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a linkage-type electric curtain rod, comprising a sliding rod, two sliding rails, two curtain pulling components, and a power component; wherein...

[0007] The slide bar is horizontal, and the two slide rails are vertical;

[0008] Two curtain pulling assemblies are positioned opposite each other, each including a curtain pulling slider, a power slider, and a connecting rod. Each curtain pulling slider is slidably mounted on one end of the sliding rod, and each power slider is slidably mounted on a slide rail. One end of the connecting rod is rotatably connected to the corresponding curtain pulling slider, and the other end is rotatably connected to the corresponding power slider.

[0009] The power assembly includes a rotary drive mechanism, a winding wheel, and two traction lines. The two traction lines are wound on the winding wheel in opposite directions. Each traction line is connected to a power slider. The rotary drive mechanism is connected to the winding wheel to drive the winding wheel to rotate.

[0010] The winding wheel is used to wind up two traction lines during rotation in one direction to make two powered sliders slide upwards. The two powered sliders, during upward sliding, drive two curtain-pulling sliders to slide towards each other along the sliding rod via two connecting rods.

[0011] During the rotation in the other direction, two traction lines are unwound to allow two powered sliders to slide down. The two powered sliders are used to drive two curtain pull sliders to slide in the opposite direction along the slide rod via two connecting rods during the descent.

[0012] Furthermore, in order to reverse the direction of the traction lines and reduce frictional resistance, the linkage-type electric curtain frame also includes at least two fixed pulleys. The fixed pulleys are in fixed positions, and each traction line is connected to the corresponding power slider after passing around the fixed pulley.

[0013] To further improve the reliability of opening the curtains, each power slider is equipped with a counterweight.

[0014] Furthermore, the winding wheel has two coaxial winding grooves, with each traction line wound in one winding groove.

[0015] Furthermore, there are two winding wheels, which are coaxial and connected to the rotary drive mechanism respectively; wherein each traction line is wound in the winding groove of one winding wheel.

[0016] Furthermore, in order to serve as a limiting element, limiting elements are provided at both ends of the slide rail to limit the sliding stroke of the power slider.

[0017] Furthermore, to prevent mistaken insertion, microswitches are installed at both ends of the sliding stroke of the power slider; wherein,

[0018] Each microswitch is connected to the rotary drive mechanism to control the rotary drive mechanism to stop working when it is touched by the corresponding power slider.

[0019] Furthermore, the rotary drive mechanism is a motor.

[0020] The present invention also relates to an electric curtain, including a rod-type electric curtain frame.

[0021] By adopting the above technical solution, the present invention has the following beneficial effects:

[0022] This invention employs a single power source to simultaneously drive two traction lines for winding and unwinding. During the closing process, the traction force of the two traction lines serves as the power to move the two curtains towards each other using two curtain-pulling sliders. During the opening process, the two traction lines are unwound, and the downward force on the power slider serves as the power to move the two curtains away from each other using two curtain-pulling sliders. Therefore, this invention can simultaneously drive the opening and closing of two curtains with a single power source, which is convenient and time-saving.

[0023] The slide bar, together with the slide rail and connecting rod on one side, forms a triangular structure, which makes the overall structure more stable and prevents the slide bar and slide rail from loosening or making abnormal noises after long-term use.

[0024] This invention controls the speed at which curtains open and close by controlling the rotational speed of the rotary drive mechanism, offering high flexibility in use.

[0025] The linkage-type electric curtain rod of this invention has a retractable traction line when not installed, which occupies a small space and is easy to store and transport. During installation, it is easy to operate and has a high installation efficiency. In the later use, if any abnormality occurs, it is also easy to repair due to the small number and simplicity of the parts.

[0026] The linkage-type electric curtain rod in this embodiment has a simple structure and principle, uses a single power source, and has low operating costs. Attached Figure Description

Detailed Implementation

[0031] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0032] Example 1

[0033] like Figures 1 to 3As shown, a linkage-type electric curtain rod includes a sliding rod 1, two sliding rails 2, two curtain pulling components 3, and a power component 4; wherein,

[0034] The slide bar 1 is horizontal, and the two slide rails 2 are vertical;

[0035] Two curtain pulling assemblies 3 are positioned opposite each other, each including a curtain pulling slider 31, a power slider 32 and a connecting rod 33. Each curtain pulling slider 31 is slidably mounted on one end of the sliding rod 1, each power slider 32 is slidably mounted on a sliding rail 2, and one end of the connecting rod 33 is rotatably connected to the corresponding curtain pulling slider 31, and the other end is rotatably connected to the corresponding power slider.

[0036] The power assembly 4 includes a rotary drive mechanism 41, a winding wheel 42, and two traction lines 43. The two traction lines 43 are wound on the winding wheel 42 respectively and in opposite directions. Each traction line 43 is connected to a power slider 32. The rotary drive mechanism 41 is connected to the winding wheel 42 to drive the winding wheel 42 to rotate.

[0037] The winding wheel 42 is used to wind up the two traction lines 43 during rotation in one direction, causing the two powered sliders 32 to slide upwards. The two powered sliders 32, during upward sliding, drive the two curtain pull sliders 31 to slide towards each other along the slide rod 1 via two connecting rods 33.

[0038] During the rotation in the other direction, two traction lines 43 are unwound to make two power sliders 32 slide down. The two power sliders 32 are used to drive two curtain pull sliders 31 to slide in the opposite direction along the slide bar 1 via two connecting rods 33 during the sliding process.

[0039] Specifically, this linkage-type electric curtain rod uses a single power source to simultaneously drive two traction lines 43 to wind and unwind. During the closing process, the traction force of the two traction lines 42 serves as the power to move the two curtain pull sliders 31 towards each other. During the opening process, the two traction lines 42 are unwinded, and the downward force on the power sliders 32 serves as the power to move the two curtain pull sliders 31 away from each other. Therefore, this embodiment can simultaneously drive the opening and closing of two curtains with a single power source, which is convenient and easy. In this embodiment, the sliding rod 1, the single-sided sliding rail 2, and the connecting rod 33... Together, they form a triangular structure, making the overall structure more stable and preventing the sliding rod 1 and sliding rail 2 from loosening or making abnormal noises after long-term use. In this embodiment, the speed of opening and closing the curtains can be controlled by controlling the rotation speed of the rotary drive mechanism 41, which is highly flexible in use. In addition, this type of linkage electric curtain rod can retract the traction line 43 when not installed, which occupies less space and is convenient for storage and transportation. During installation, it is easy to operate and has a high installation efficiency. In the later use, if any abnormality occurs, it is also easy to repair due to the small number of simple parts. Furthermore, this linkage electric curtain rod has a simple structure and principle, uses a single power source, and has low operating costs.

[0040] In this embodiment, preferably, as follows: Figures 1 to 3 As shown, the linkage-type electric curtain rod also includes at least two fixed pulleys 5. The fixed pulleys 5 are in fixed positions, and each traction line 43 passes around the fixed pulley 5 and is connected to the corresponding power slider 32.

[0041] Specifically, a fixed pulley 5 is provided to facilitate the reversal of the traction line 43 and to reduce frictional resistance.

[0042] In this embodiment, preferably, as follows: Figures 1 to 3 As shown, each power slider 32 is equipped with a counterweight 6.

[0043] Specifically, the counterweight 6 is provided to effectively prevent the curtains from failing to open smoothly due to insufficient gravity of the power slider 32.

[0044] In this embodiment, the winding wheel 42 has two coaxial winding grooves, and each traction line 43 is wound in one winding groove. Alternatively, two winding wheels 42 are configured, with the two winding wheels 42 coaxial and respectively connected to the rotary drive mechanism 41; wherein each traction line 43 is wound in the winding groove of one winding wheel 42.

[0045] In this embodiment, preferably, as follows: Figures 1 to 3 As shown, the slide rail 2 is provided with limiting members 7 at both ends to limit the sliding stroke of the power slider 32.

[0046] Thus, the limiting component 7 can serve as a limiting element.

[0047] In this embodiment, preferably, microswitches are respectively provided at both ends of the sliding stroke of the power slider 32; wherein,

[0048] Each microswitch is connected to the rotary drive mechanism 41 to control the rotary drive mechanism 41 to stop working when it is touched by the corresponding power slider 32.

[0049] The displacement of the power slider 32 can be controlled by adjusting the single working time of the rotary drive mechanism 41. A microswitch is provided to ensure that the rotary drive mechanism 41 stops operating promptly when the power slider 32 reaches its limit position if the rotary drive mechanism 41 fails to stop normally due to an malfunction, thus preventing mistaken operation.

[0050] like Figures 1 to 3 As shown, the rotary drive mechanism 41 can be a motor, specifically a self-locking motor.

[0054] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
