Description

Technical Field

[0001] The invention relates to the technical field of smart home, in particular to an electric Roman rod double opening and closing curtain and a single opening and closing curtain. Background Art

[0002] Curtains are indispensable interior decoration materials because of their shielding, decorative and indoor light regulating functions. Roman rod curtains are widely used interior decoration curtains besides track curtains due to their simplicity and beauty. Electric Roman rod curtains are more convenient and labor-saving than traditional manual Roman rod curtains, and were once a product that people paid attention to. However, due to the limitations of existing electric Roman rod technology and problems existing during use, their development prospects are restricted.

[0003] The existing electric Roman rod technology has the following problems.

[0004] 1. Modern window structure: Considering people's need for indoor lighting, many windows adopt the design of whole window against side wall or single-side window against side wall. The existing electric Roman rod is designed with transmission belt for forward and backward movement. Due to the limitation of its technical structure, the motor and transmission box can only be connected to the outside of the two ends of the rod body. As a result, after the curtains are mounted, even if the Roman head is not used, the curtains at both ends of the rod body cannot be against the side wall, resulting in light leakage, so consumers have to give up the electric Roman rod.

[0005] Second, the existing electric Roman rod is a structural design in which a pulley pulls a curtain. The double-opening and closing curtain is a symmetrically moving pulley set on the left and right of the rod body, so that the force pulling a curtain is concentrated on this pulley. After the curtain is closed, the curtain mounted on the two pulleys is pulled and deformed due to the force, which affects the appearance.

[0006] 3. After the existing electric Roman rod Roman ring double opening and closing curtains and electric Roman rod hook ring double opening and closing curtains are closed, the two curtains cannot close together in the middle and light leakage occurs. Some people sew magnetic buckles on the curtains to compensate for the light leakage defect. Due to the magnetic effect, the curtains are pulled unnaturally, and the magnetic buckle heads are exposed to the outside, affecting the appearance.

[0007] 4. The electric Roman rod motor system currently in use is large in size and is too protruding when wrapped in the folds of the curtains, affecting the appearance. The motor system is fixed with a snap-on design, which makes it easy to shake when working. Some users have even reported that the motor system has fallen off, posing a safety hazard.

[0008] 5. At present, there is a simple curtain machine with a built-in lithium battery and plug-and-play with patent number CN201910420751. Its disadvantages are that it is large in size, is too protruding when wrapped in the folds of the curtains, and part of the machine body is exposed, which affects the appearance. It is also inconvenient to charge and has loud working noise. It cannot solve the problem of light leakage in the middle of the two curtains of the Roman rod double-opening curtains. Summary of the invention

[0009] Therefore, it is necessary to provide an electric Roman pole with complete functions, firm installation, beautiful appearance and practicality.

[0010] The present invention provides an electric Roman rod double-opening and closing curtain and a single-opening and closing curtain, which are used to solve the technical problems existing in the prior electric Roman rod technology that the whole window abuts against the side wall and the curtain leaks light on both sides, or the single-sided window abuts against the side wall and the curtain leaks light on one side, the technical problem that a single pulley pulls a curtain and the curtain is pulled and deformed, the technical problem that after the electric Roman rod Roman ring double-opening and closing curtain and the electric Roman rod hook ring double-opening and closing curtain, the two curtains cannot be closed together in the middle and light leaks out, and the technical problems that the electric Roman rod motor system is large in size and affects the appearance, and the motor system is not firmly installed.

[0019] In one embodiment, the mounting bracket is divided into a wall-mounted bracket and a ceiling-mounted bracket, the wall-mounted bracket includes a wall-mounted main bracket and a wall-mounted auxiliary bracket, and the ceiling-mounted bracket includes a ceiling-mounted main bracket and a ceiling-mounted auxiliary bracket.

[0020] Compared with the prior art, the advantages of the present invention are as follows: the present invention has a simple structure and is easy to install. The present invention adopts an innovatively designed main transmission device and an auxiliary transmission device to be installed in the rod body, which can make the transmission belt move up and down in a circular shape. A hole is opened on one side wall of the rod body, and the motor shaft of the motor is connected to the main transmission wheel of the main transmission device in the rod body through the motor shaft plug hole on the side wall of one side of the rod body. For the window structure in which the whole window is against the side wall, a method of not using a Roman head or a window structure in which a single-side window is against the side wall is adopted to use a Roman head, so that the purpose of preventing light leakage when the curtain is against the side wall is achieved. The shaft hole of the main transmission wheel is an innovative design of the same shaft hole with two shaft diameters. The invention adopts an innovative pulley group, in which the upper toothed belt of the transmission belt passes through the cavity of the lower toothed belt buckle pulley and the lower toothed belt buckle auxiliary pulley propeller, so that the pulley and the auxiliary pulley propeller engaged with the upper toothed belt of the transmission belt and the pulley and the auxiliary pulley propeller engaged with the lower toothed belt of the transmission belt can make symmetrical movements on both sides of the center of a straight line and drive the auxiliary pulleys on both sides to make symmetrical movements at the same time, so as to realize the purpose of double opening and closing curtains. Each curtain is provided with a pulley and an auxiliary pulley. When the curtains are closed, the auxiliary pulley can be moved symmetrically on both sides of the center of a straight line. The auxiliary pulley is pushed forward by the auxiliary pulley propeller. Since the force of closing the curtain is on the auxiliary pulley propeller, the curtain at the pulley position is more beautiful and natural. When the curtain is opened, the pulley pushes the auxiliary pulley backward. Since the auxiliary pulley propeller is located in the rod body as a whole, after the curtain is fully opened, the auxiliary pulley propeller enters the rod body behind the gathered curtain, so that the gathered curtain fits naturally. The present invention adopts an innovatively designed dual-purpose curtain opening and closing angle adjuster. The electric Roman rod Roman ring curtain and the electric Roman rod hook ring curtain can respectively achieve the required curtain opening and closing degree by adjusting the bending angle of the upper and lower adjusting pieces of the adjuster, thereby solving the problem. The existing electric Roman rod double-opening curtains have technical problems such as light leakage in the middle of the two curtains not closing together and light leakage at the edges of the single-opening curtains. The curtains have shielding properties. The DC motor system of the present invention is small in size and naturally beautiful when wrapped in the folds of the curtains. The motor system can be powered by AC power or lithium batteries. The curtain opening and closing has three control modes: voice control, remote control, and manual. The clamp bracket for fixing the motor system of the present invention can firmly and firmly fix the motor system on the rod body and the main bracket. The motor system runs stably without shaking, and the installation and maintenance are simple and convenient. The motor system can be installed or disassembled by gently lifting the rod body and moving the clamp bracket left and right. BRIEF DESCRIPTION OF THE DRAWINGS

[0087] The implementation principle of the three-bracket electric Roman rod double opening and closing curtain is to close the curtain, start the motor system 2, and the transmission belt 31 of the transmission device 3 makes an upward and downward return motion, driving the upper row of toothed belt buckle pulley 4 and the upper row of toothed belt buckle auxiliary pulley propeller 7 and the lower row of toothed belt buckle pulley 5 and the lower row of toothed belt buckle auxiliary pulley propeller 8 to make reverse symmetrical motion on both sides with the rod body 1 as the center and move closer to the center of the rod body 1. At the same time, the upper row of toothed belt buckle auxiliary pulley propellers 7 and the lower row of toothed belt buckle auxiliary pulley propellers 8 on both sides of the center of the rod body 1 push their respective auxiliary pulleys 6 to make reverse symmetrical motion on both sides with the rod body 1 as the center and move closer to the center of the rod body 1, thereby driving the double opening and closing curtains mounted in the dual-purpose curtain opening and closing angle adjuster 9 and the two auxiliary pulleys 6 mounted on the upper row of toothed belt buckle pulley 4 and the lower row of toothed belt buckle pulley 5 to close; open the curtain, start the motor system 2, and the transmission belt 31 of the transmission device 3 makes an upward and downward return motion. The upper toothed belt buckle pulley 4 and the upper toothed belt buckle auxiliary pulley propeller 7 and the lower toothed belt buckle pulley 5 and the lower toothed belt buckle auxiliary pulley propeller 8 move symmetrically in the opposite direction with the rod body 1 as the center to move toward the two ends of the rod body 1. At the same time, the upper toothed belt buckle pulley 4 and the lower toothed belt buckle pulley 5 on both sides of the center of the rod body 1 push their respective auxiliary pulleys 6 to move symmetrically in the opposite direction with the rod body 1 as the center to move toward the two ends of the rod body 1. The upper toothed belt buckle type auxiliary pulley propeller 7 and the lower toothed belt buckle type auxiliary pulley propeller 8, which make reverse symmetrical movements on both sides of the rod body 1, move toward both ends of the rod body 1 at the same time. Since the upper toothed belt buckle type auxiliary pulley propeller 7 and the lower toothed belt buckle type auxiliary pulley propeller 8 are located in the rod body 1 as a whole, they will finally enter the rod body 1 behind the two gathered curtains. At this point, the double-opening curtain is fully opened naturally after the two curtains are gathered and fitted together.

[0088] The implementation principle of the double-bracket electric Roman rod single opening and closing curtain is to close the curtain, start the motor system 2, and the transmission belt 31 of the transmission device 3 makes an upward and downward return motion, driving the upper row of toothed belt buckle pulley 4 and the upper row of toothed belt buckle auxiliary pulley propeller 7 to move forward. At the same time, the upper row of toothed belt buckle auxiliary pulley propeller 7 pushes the auxiliary pulley 6 to move forward, thereby driving the dual-purpose curtain opening and closing angle adjuster 9 mounted on the upper row of toothed belt buckle pulley 4 and the single opening and closing curtain in the auxiliary pulley 6 to close, open the curtain, and start the motor System 2, the transmission belt 31 of the transmission device 3 makes an up and down return motion, driving the upper row of toothed belt buckle pulley 4 and the upper row of toothed belt buckle auxiliary pulley propeller 7 to move backward. At the same time, the upper row of toothed belt buckle pulley 4 pushes the auxiliary pulley 6 to move backward, and the upper row of toothed belt buckle auxiliary pulley propeller 7 moves backward at the same time. Since the upper row of toothed belt buckle auxiliary pulley propeller 7 is located as a whole in the rod body 1, it will finally enter the rod body 1 behind the folded curtain. At this point, the single-opening curtain is naturally fully opened after being folded.
