[0030] The following further explains the present utility model in combination with the detailed implementation mode.

[0031] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation on the present utility model.

[0032] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, "a plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "attachment", "fixation" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] In the present utility model, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.

[0035] The present utility model provides an adjustable multi-panel curtain, which is used in areas to be shielded such as buildings or vehicles, for example, on doors and windows. Referring to the attached Figure 1 , specifically, the adjustable multi-panel curtain has an upper beam 1, which is installed on the upper edge of the door or window, and usually its installation position height is higher than the top height of the door or window. A driving mechanism and a transmission mechanism are provided in the accommodating cavity of the upper beam 1. In this embodiment, the multi-panel curtain is an electric curtain, so the driving mechanism is a motor. After the motor is connected to an external power source or a battery, it can provide electric power. After the electric power is output, it is transmitted to the transmission mechanism, and the transmission mechanism drives the lifting assembly to drive the shielding unit 2 to move;

[0036] The adjustable multi-panel curtain of the present utility model, for facilitating the adjustment of the shielding area, has at least one set of shielding units 2. At least one set of the shielding units 2 is movable. The shielding units 2 are stacked in parallel front and back. The movable shielding units 2 are vertically lifted and lowered to adjust the area to be shielded. The shielding units 2 shield the area to be shielded in a vertically spaced arrangement relationship. When there are two or more sets of shielding units, the shielding units are parallel to each other. When all the shielding units 2 are fully unfolded, they exactly completely shield the area to be shielded. When the shielding units 2 move up and down to increase the overlapping area with each other, the shielding area can be adjusted.

[0037] The lifting assembly for moving the shielding unit 2 up and down, referring to the attached Figure 3 , connects the movable shielding unit 2 to the transmission mechanism. After the driving force of the driving mechanism is output, it is transmitted to the lifting assembly through the transmission mechanism, and the lifting assembly connects the movable shielding unit 2 to drive it to move up and down.

[0038] The adjustable multi-panel curtain of the present utility model has multiple groups of shielding units 2. The shielding units 2 are independent of each other and can be moved and positioned separately. Different overlapping areas between them result in different shielding areas. For example, all the shielding units 2 can be lifted to the upper or lower end of the area to be shielded, that is, all the shielding units 2 are completely overlapped, achieving the maximum light transmission effect, and the lower or upper part of the area to be shielded can be selected for light transmission, such as Figure 2 , Figure 8 as shown; or the shielding units 2 can be lifted and lowered so that some are located at the upper end of the area to be shielded and some are located at the lower end of the area to be shielded, achieving the effect of light transmission in the middle area. And since the shielding units 2 can be moved and adjusted to different overlapping areas, the light transmission area in the middle area can also be adjusted.

[0039] As a further improved embodiment, the shielding unit 2 has an upper edge and a lower edge. To prevent light leakage during shielding, when completely shielding the area to be shielded, the lower edge of each shielding unit 2 overlaps with the upper edge of the shielding unit 2 directly below it. The overlapping area is generally limited to the edge part and should not be excessive to prevent reducing the light transmissible area and increasing the processing cost.

[0040] As a further improved embodiment, the lifting assembly uses a pull rope 31, a rope winding rod or a pull rope 31, a pulley. The rope winding rod or the pulley is arranged in the accommodating cavity of the upper beam 1. One end of the pull rope 31 is fixed to the rope winding rod or the pulley, and the other end is fixed to the shielding unit 2. The end of the shielding unit 2 where the pull rope 31 is not fixed is usually a free end, that is, in a freely hanging state. By taking in and releasing the pull rope 31, the height position of the shielding unit 2 can be changed. Specifically, the rope winding rod can be driven by the power transmitted by the driving mechanism to rotate, so that the pull rope 31 can be wound and taken in or released by the rope winding rod, or the pulley is driven by the driving mechanism to slide along the slide rail arranged in the accommodating cavity, thereby pulling and releasing the pull rope 31.

[0041] In a preferred embodiment, the lifting assembly further has at least one vertical lifting guide rail 32; most preferably two vertical lifting rails, with one vertical lifting rail arranged on each side of the area to be shielded, referring to the attached Figure 7 . The pull rope 31 is arranged in the vertical lifting rail, which is more aesthetically pleasing.

[0042] As a further improved embodiment, the shielding unit 2 includes a total of three groups: a first shielding unit 21, a second shielding unit 22, and a third shielding unit 23. For the convenience of description, the shielding unit closest to the outermost edge of the upper beam 1 is listed as the first shielding unit 21, followed by the second shielding unit 22 and the third shielding unit 23 in sequence. All three groups of shielding units are movable, or the first shielding unit 21 is immovable while the second and third shielding units are movable. It should be noted that the shielding unit 2 can be one group, two groups, three groups, four groups..., which is determined according to the area of the area to be shielded, the area ratio of the shielding unit 2, the customized needs of consumers, etc. Several non-exhaustive setting methods of the shielding unit are listed for reference, referring to the attachedFigure 1 There are three sets of shielding units, including a first shielding unit 21, a second shielding unit 22, and a third shielding unit 23, a total of three sets. Among them, the first shielding unit 21 is immovable, and the second shielding unit 22 and the third shielding unit 23 are both movable. Refer to the attached Figure 2 There are two sets of movable second shielding unit 22 and third shielding unit 23, and the two sets of shielding units are adjusted to a completely overlapping state. Refer to the attached drawings Figure 10 There is only one set of movable shielding unit 2, and the movable shielding unit can flexibly shield the area to be shielded. Refer to the attached Figure 11 There are two sets of shielding units, among which the fourth shielding unit 24 is immovable and the fifth shielding unit 25 is movable; three sets of shielding units are more commonly used and have lower costs.

[0043] A preferred embodiment is that one set of shielding unit 2 is detachably connected to the upper beam 1. More preferably, the first shielding unit 21, which is the set of shielding unit closest to the outermost edge of the upper beam 1, is detachably connected to the upper beam 1. In this way, when the lifting assembly does not have a vertical lifting track, in the fully shielded state, the user will not see the pull cord 31, and the integrity and aesthetics are better.

[0044] As a further improved embodiment, refer to the attached Figures 4 to 6 , the detachable connection method between the shielding unit 2 and the upper beam 1 is by inserting into the chute 11. Specifically, a chute 11 is provided on the outer edge of the upper beam 1, and a mating insertion strip is provided on the upper edge of the shielding unit 2. When in use, the insertion strip of the shielding unit 2 is inserted from one end of the chute 11 and slides along the length direction of the chute 11 to complete the insertion of the shielding unit 2 and the upper beam 1. The detachable design is convenient for installation and maintenance.

[0045] As a further improved embodiment, to meet the basic function of shielding, the shielding unit 2 necessarily includes a curtain. Refer to the attached Figure 4 、 9 , the curtain material is at least one of pure cotton, linen, polyester, silk, PVC (polyvinyl chloride), and can be made of a single material or a composite material. In terms of touch, it can be a soft material such as the feel of cloth, or a harder feel such as that of a plastic plate. The materials, colors, light transmittance, etc. of the curtains of different sets of shielding units 2 can be the same or different, and different materials and colors can obtain a more diverse usage experience.

[0046] As a further improved embodiment, refer to the attached Figure 9, to make the lifting component, for example, to connect the pull rope 31 to the shielding unit 2 more conveniently, the shielding unit 2 includes an upper curtain rod 231. One long side of the upper curtain rod 231 is fixed with a curtain cloth 232, and through holes are formed in the opposite long side. The pull rope 31 can be inserted into the through holes for fixation, so as to connect the shielding unit 2 with the lifting component. Relative to the upper curtain rod 231, the curtain cloth 232 is further provided with a lower curtain rod 233. The arrangement of the upper and lower curtain rods 233 helps the curtain cloth 232 maintain its stiffness, and the lower curtain rod 233 also adds a certain weight, which helps the curtain cloth 232 to hang vertically. In addition, the detachable shielding unit 2 can be provided with an upper curtain rod 231, and the insertion strip is arranged on the upper curtain rod 231. The detachable shielding unit 2 can be provided with a lower curtain rod 233 or not.

[0047] As a further improved embodiment, the shapes and areas of the shielding units 2 are generally the same, and the shape is most commonly rectangular, which is more convenient for processing and installation.

[0048] The materials, reagents and experimental equipment involved in the embodiments of the present utility model are all commercially available products that conform to the field of door and window shielding equipment, unless otherwise specified.

[0049] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the core technology of the present utility model, improvements and refinements can still be made, and these improvements and refinements should also fall within the scope of patent protection of the present utility model. Any changes within the meaning and scope equivalent to the claims of the present utility model should be considered to be included within the scope of the claims.
