[0002] Smart homes are becoming more and more popular. For electric curtains, the existing curtain racks have two curtains that are controlled separately, and two power mechanisms need to be configured, resulting in high curtain rack implementation costs and difficulty in ensuring synchronization of the two power mechanisms. In addition, the curtain racks are relatively long and have many parts, making transportation difficult, and the installation and maintenance process is relatively cumbersome.

[0003] For example, the patent application number is CN202322525612.X, and the patent name is a patent for an electric curtain that is easy to install. The above-mentioned situation exists. The patent application number is CN202321175387.5, and the patent name is a dual-drive device and electric curtain applied to electric curtains. Although communication transmission is achieved through communication line connection to maintain the synchronous operation of the first drive member and the second drive member, there are still problems such as the need to configure two sets of power mechanisms, high implementation cost, difficult transportation, and troublesome installation and maintenance.

[0011] During the rotation in the other direction, two traction lines are unwound to make the two power sliders slide down. The two power sliders are used to drive the two curtain pulling sliders to slide back along the slider rods through two connecting rods during the sliding process.

[0012] In order to further reverse the traction line and reduce friction resistance, the connecting rod type electric curtain rack also includes at least two fixed pulleys, the fixed pulleys are fixed in position, and each traction line is connected to the corresponding power slider after passing around the fixed pulley.

DETAILED DESCRIPTION

[0031] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0032] Embodiment 1

[0033] like Figures 1 to 3 As shown, a connecting rod type electric curtain frame includes a slide rod 1, two slide 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 opposite to each other, and respectively include 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 slide bar 1, and each power slider 32 is slidably mounted on a slide rail 2. 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 respectively wound on the winding wheel 42 and wound in opposite directions. Each traction line 43 is connected to a power slider 32. The rotary power member is connected to the winding wheel 42 to drive the winding wheel 42 to rotate.

[0037] The winding wheel 42 is used to reel in two traction wires 43 while rotating in one direction to make the two power sliders 32 slide upward. The two power sliders 32 are used to drive the two curtain pulling sliders 31 to slide toward each other along the slide rod 1 through the two connecting rods 33 during the sliding process; and

[0038] During the rotation in the other direction, the two traction wires 43 are unwound to make the two power sliders 32 slide down. The two power sliders 32 are used to drive the two curtain pulling sliders 31 to slide backward along the slide rod 1 through the two connecting rods 33 during the sliding process.

[0039] Specifically, this connecting rod type electric curtain rack adopts a single power to drive two traction wires 43 to be retracted and unreeled at the same time. In the process of closing the curtain, the traction force of the two traction wires 42 is used as the power to make the two curtain pulling sliders 31 drive the two curtains to move toward each other. In the process of opening the curtain, the two traction wires 42 are unreeled, and the downward force exerted on the power slider 32 is used as the power to make the two curtain pulling sliders 31 drive the two curtains to move in the opposite direction. Therefore, this embodiment can drive the two curtains to open and close at the same time by a single power, which is convenient and trouble-free. The slide bar 1 of this embodiment is connected with the single-sided slide rail 2 and the connecting rod 33 Together they form a triangular structure, making the overall structure relatively stable, and preventing the slide bar 1 and the slide rail 2 from loosening or making unusual noises after long-term use. By controlling the rotation speed of the rotary drive mechanism 41, the speed of opening and closing the curtain can be controlled in this embodiment, and the use flexibility is high. In addition, when the connecting rod type electric curtain rack in this embodiment is not installed, the traction line 43 can be retracted, and the overall space occupied is relatively small, which is convenient for storage and transportation. During the installation process, the operation is convenient and the installation efficiency is relatively high. In the later use process, if an abnormality occurs, it is also convenient to repair due to the small number of parts and the simplicity. Furthermore, this connecting rod type electric curtain rack has a simple structure and principle, adopts a single power, and has a low cost of use.

[0040] In this embodiment, preferably, Figures 1 to 3 As shown, the connecting rod type electric curtain frame also includes at least two fixed pulleys 5, the fixed pulleys 5 are fixed in position, and each traction line 43 is connected to the corresponding power slider 32 after passing around the fixed pulley 5.

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

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

[0043] Specifically, the counterweight block 6 can be provided to effectively avoid the situation where the curtain cannot be opened 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. Or the winding wheel 42 is configured with two, the two winding wheels 42 are coaxial, and are respectively connected to the rotating drive mechanism 41; wherein each traction line 43 is wound in the winding groove of one winding wheel 42.

[0045] In this embodiment, preferably, Figures 1 to 3 As shown, both ends of the slide rail 2 are respectively provided with limiting members 7 for limiting the sliding stroke of the power slider 32 .

[0046] In this way, the limiting member 7 can play a limiting role.

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

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

[0049] The single displacement of the power slider 32 can be controlled by controlling the single working time of the rotation drive mechanism 41. The micro switch can be set to make the rotation drive mechanism 41 stop working in time when the power slider 32 moves to the limit position when the rotation drive mechanism 41 cannot stop normally due to an abnormality, thereby playing a foolproof role.

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