Technical Field

[0001] This utility model relates to electric curtains, and more particularly to a solar-powered electric curtain. Background Technology

[0002] In modern homes, motorized blinds, such as sunshade blinds and Venetian blinds, are widely used. The motor is installed in the upper track of the blind, and the blind moves through a roller tube mounted on the motor's output shaft.

[0003] In the current field of electric blinds, mains power or solar power are commonly used. Due to the superior energy-saving characteristics of solar power, it is increasingly widely used. For example, Chinese Patent Application No. 202221929884.5 discloses a Venetian blind comprising: a sealed housing, a drive motor fixed within the sealed housing, a roller tube connected to the drive motor, curtain slats, and a solar panel. The solar panel includes a solar panel and a battery. The battery is fixed within the sealed housing, and the solar panel is electrically connected to the battery, which is also electrically connected to the drive motor. Another example is Chinese Patent Application No. 201520818265.2, which discloses a solar-powered electric roller blind. It has a roller tube containing a tubular motor, a rotating wheel, and a tail plug. One end of the roller tube has a tail plug mounting bracket, and the other end has a motor mounting bracket. The tubular motor is connected to a battery via wires, and a solar panel is mounted on the battery.

[0004] In the aforementioned existing technologies, the solar energy device needs to connect to the motor via exposed wires extending into the frame, which poses a safety hazard. Therefore, further improvements are needed. Utility Model Content

[0026] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions.

[0027] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0028] See Figures 1-6 A solar-powered electric curtain includes a drive motor, a mounting housing 2, a roller tube 3, a solar panel 4, a window frame 5, and a curtain fabric 6. The window frame 5 includes two spaced-apart supports 51, each support 51 extending vertically, and the curtain fabric 6 is at least partially located between the two supports 51, with the lower end of the curtain fabric 6 rising and falling between the two supports 51.

[0029] Mounting housing 2 is located at the top of window frame 5. Mounting housing 2 is preferably cuboid in shape, and its length extends in the width direction of window frame 5 (i.e., in the direction of the horizontal line connecting one bracket 51 to another bracket 51). Figure 1(As shown in the left-right direction). The lower end of the mounting housing 2 has a first through hole 21, through which the curtain 6 can pass, such that part of it is inside the mounting housing 2 and part of it is below the mounting housing 2. The part below the mounting housing 2 is located inside the window frame 5. The length direction of the first through hole 21 is the width direction of the window frame 5. Preferably, the first through hole 21 is slit-shaped, and its width is adapted to the thickness of the curtain 6, just enough to allow the curtain 6 to move relative to the mounting housing 2, avoiding excessive width that would allow water, dust, etc. to enter the mounting housing 2.

[0030] The drive motor and the roller tube 3 are housed within the mounting housing 2. The roller tube 3 is a hollow cylinder. The upper end of the curtain 6 is fixed to the roller tube 3 and can be wound around it. By rotating the roller tube 3, the length of the curtain 6 wound on the roller tube 3 can be changed, thereby changing the height of the lower end of the curtain 6 within the window frame 5, thus altering the lighting in the room. The drive motor, not fully shown in the accompanying drawings, is installed within the roller tube 3 and is used to drive the roller tube 3 to rotate. Normally, in the installed state, the axis of rotation of the roller tube 3 extends horizontally and is parallel to the width direction of the window frame 5. The structure of the drive motor and the method of driving the roller tube 3 to rotate are based on existing technology. The drive motor includes an end cap 11 located at its axial end.

[0031] The axial direction of the drive motor is the same as the length direction of the mounting housing 2. The mounting housing 2 has openings at both ends along its length to facilitate the installation of the drive motor and the reel 3 inside the mounting housing 2. Caps 7 are provided at both ends along the length direction of the mounting housing 2 to enclose the drive motor and the reel 3 within the mounting housing 2.

[0032] The solar panel 4 is located on the outer side of the mounting housing 2. When the electric curtain is installed, the solar panel 4 is located on the outdoor side of the mounting housing 2 to receive sunlight and convert it into electrical energy. One end of the solar panel 4 corresponds to the end cap 11 of the drive motor. Since the length of the solar panel 4 is usually less than the width of the curtain 6, the other end may not correspond to the end cap 11 of the drive motor.

[0033] The solar panel 4 is preferably attached tightly to the mounting housing 2. A second through hole 22 may be provided on the side of the mounting housing 2 adjacent to the solar panel 4. A first connecting end 41 is provided on the end of the solar panel 4 corresponding to the end cover 11. A second connecting end 111 is provided on the end cover 11 of the drive motor (which may be one end cover 11 or two end covers 11). The first connecting end 41 and the second connecting end 111 are aligned, and each connecting end is provided with an electrical connection device, such as an electrode plate or a wire. One connecting end passes through the second through hole 22 to connect with the other connecting end, thereby realizing mechanical and electrical connection. To facilitate mechanical connection, the first connecting end 41 and the second connecting end 111 are preferably connected by a plug-in joint, that is, one connecting end is protruding, and the other connecting end is formed with a groove to receive the protrusion. In this embodiment, the first connecting end 41 is protruding, and the second connecting end 111 is grooved. The first connecting end 41 passes through the second through hole 22 and is inserted into the second connecting end 111. The end cap 11 can be electrically connected to the battery inside the drive motor via wires to provide power.

[0034] With the installation method of the solar panel 4 and drive motor of this utility model, exposed wires are no longer used. All wires are inside the mounting housing 2. The first connection end 41 and the second through hole 22 of the mounting housing 2 can be sealed to ensure airtightness, so there is no safety hazard.
