FIG. 8 illustrates a schematic structural view of a curtain 600 provided in accordance with embodiments herein;

fig. 9 shows a partial enlarged view C of fig. 8. As shown in fig. 1A-9, the curtain 600 may be positioned between the fixed frame 200 and the movable frame 400 and moved between the first position and the second position to vary the area covered on the target window 003. When the curtain 600 is in the second position, the target window 003 is fully occluded. When the curtain 600 is located at the second position, the movable frame 400 is close to the fixed frame 200 and is closed relative to the fixed frame 200 to clamp the curtain 600, so that a sealing connection is formed between the curtain 600 and the fixed surface 004 of the target window 003, air between two sides of the curtain 600 in the target window 003 cannot flow through a gap between the curtain 600 and the target window 003, and meanwhile, sunlight cannot pass through the curtain 001 through the gap between the curtain 600 and the target window 003, so that heat exchange is reduced, an energy-saving effect is improved, and impurities such as mosquitoes and dust are blocked.

The curtain 600 may include a curtain 620 and a guide mechanism 660. The curtain 620 may be any type of light-blocking material, and may be non-transparent, or may be a transparent or translucent light-guiding material. The blocking may be blocking some or all of the light to block it from passing through the curtain 620. The blocking may be a blocking of a predetermined proportion of light having a predetermined wavelength, such as reflected ultraviolet light, infrared light, a portion of visible light, and the like. The curtain 620 in this application is exemplified by a transparent light guide curtain 620. In some embodiments, the light guide curtain 620 may be completely transparent or may be made of a medium that partially reflects and partially penetrates the light guide. For example, the light guide curtain 620 may reflect light of a predetermined wavelength, such as ultraviolet light, infrared light, a portion of visible light, and so on, in a predetermined proportion. In some embodiments, light directing curtain 620 may include at least one transparent base film and at least one partially reflective film. A partially reflective film may be attached on the transparent base film to reflect a part of wavelengths of light among the light rays. The light guide curtain 620 may allow a predetermined proportion of visible light to pass through, for example, 0-0.1%, 1%, 2%, 5%, 7%, 8%, 10% of visible light to pass through, etc. For example, the partially reflective film may be a metal plating film, such as an aluminum plating film, of a predetermined thickness. The partially reflective film material and thickness can be modified to modify the light transmittance of the light guide curtain 620 according to the usage requirements. The transparent base film may increase the perspective effect of the light guide curtain 620. Therefore, a user can see the scenery outside the window through the light guide curtain 620 without obstacles, and can also reflect the light rays with preset proportion by using the light guide curtain 620, so that the indoor temperature is not too high to be heated by the light rays, and the effect of energy conservation is achieved.

In some embodiments, light directing curtain 620 may include multiple layers of partially reflective film, for example, a first layer of partially reflective film may be a polyester transparent layer to block ultraviolet light, a second layer of partially reflective film may be a polyester metal coating to reflect solar heat, and a third layer of partially reflective film may be a polyester film layer to transmit visible light.

In some embodiments, the curtain 620 can be an air impermeable material, such as where the curtain 620 is a non-porous material. At this time, when the curtain 620 is located at the second position, the movable frame 400 is closed relative to the fixed frame 200 to clamp the curtain 620, so that a sealed connection is formed between the curtain 620 and the fixed surface 004 of the target window 003, and air between two sides of the curtain 620 in the target window 003 cannot circulate through a gap between the curtain 620 and the target window 003 or through the curtain 620 itself, so as to isolate air circulation between two sides of the curtain 600 in the target window 003; meanwhile, light cannot pass through the curtain 001 through a gap between the curtain 620 and the target window 003, so that heat exchange is reduced, the energy-saving effect is improved, and impurities such as mosquitoes and dust are blocked.

In some embodiments, the curtain 620 can be made of a breathable material, such as air permeable holes disposed on the curtain 620, and such as the curtain 620 is made of breathable material. Taking the target window 003 as a rectangle as an example, the light guide curtain 620 may also be a rectangle. The light guide curtain 620 may be located between the fixed frame 200 and the movable frame 400, and the width of the light guide curtain 620 in the X direction should at least cover the width of the inner edges of the fixed frame 200 and the movable frame 400, so as to ensure that the light guide curtain 620 can be clamped between the movable frame 400 and the fixed frame 200 to form a seal when the movable frame 400 and the fixed frame 200 are closed. The light guide curtain 620 may include a fixed end 621 and a movable end 622.

The fixed end 621 may be fixed. The movable end 622 may be disposed opposite to the fixed end 621 and may be movable in the target direction between the first position and the second position relative to the fixed end 621 to change a shielding area of the light guide curtain 620 for the target window 003. In some embodiments, the movable end 622 may include a gravity component to increase gravity to make the movable end 622 move more smoothly, and the light guide curtain 620 may keep the surface smooth and wrinkle-free during moving, and the gravity component may be disposed to reduce the resistance to moving and to make the movable end 622 stop at any position between the first position and the second position.

In some embodiments, the curtain 600 may also include a guide mechanism 660. The guide mechanism 660 may be located at the moving end 622 and between the fixed bezel 200 and the movable bezel 400. The movable end 622 is movable linearly along the fixed frame and the movable frame when moving between the first position and the second position. For example, the guide mechanism 660 may be slidably or rollably coupled to the fixed bezel 200 and the movable bezel 400.

FIG. 10 shows a cross-sectional view D-D of FIG. 1A; FIG. 11 shows a cross-sectional view E-E of FIG. 1B. As shown in fig. 1A to 11, the connection between the guiding mechanism 660 and the fixed frame 200 and the movable frame 400 may be that the guiding mechanism 660 is slidably connected to the guiding path formed by the first guiding groove 260 and the second guiding groove 460, and when the movable end 622 moves between the first position and the second position, the guiding mechanism 660 may slide along the guiding path formed by the first guiding groove 260 and the second guiding groove 460. Here, the width of the guide mechanism 660 in the Y direction is greater than the depths of the first guide groove 260 and the second guide groove 460, and thus, by the time the guide mechanism 660 is in the first guide groove 260 and the second guide groove 460, the fixed frame 200 and the movable frame 400 are separated by the interference of the guide mechanism 660.

When the movable end 622 is at a position other than the second position, the guide mechanism 660 can respectively abut against the fixed frame 200 and the movable frame 400, so that the movable frame 400 is away from the fixed frame 200 and is opened relative to the fixed frame 200. Specifically, the guide mechanism 660 may abut against the first guide groove 260 and the second guide groove 460, respectively, so that the movable frame 400 is away from the fixed frame 200 and is opened relative to the fixed frame 200, so that the movable end 620 may freely move between other positions than the second position.

The fixed frame 200 and the movable frame 400 are formed with a parking space accommodating guide mechanism 660 at the second position when closed. The parking space may be a notch provided on the fixed frame 200 and/or the movable frame 400 at the second position. For example, when the movable end 620 is located at the second position, the notch 470 formed at the bottom end of the second guide groove 460 allows the guide mechanism 660 to enter the notch 470 and separate from the second guide groove 460, the guide mechanism 660 no longer abuts against the second guide groove 460, so as to separate from the movable frame 400, and the movable frame 400 is close to the fixed frame 200 under the attraction force of the first magnetic body 280 and the second magnetic body 480 and is closed relative to the fixed frame 200, so as to clamp the light guide curtain 620. At this time, the movable frame 400 is adsorbed together with the fixed frame 200, and the light guide curtain 620 is clamped between the fixed frame 200 and the movable frame 400, and the fixed frame 200, the light guide curtain 620 and the movable frame 400 form a sealing structure, so that air on two sides of the curtain 600 is isolated and cannot circulate, and heat exchange cannot be performed, so that the curtain 001 can achieve the energy-saving effect of the light guide curtain 620, and the energy-saving efficiency of the curtain 001 is improved. Specifically, the fixed bezel 200 and the movable bezel 400 may clamp edges of the light guide curtain 620, including edges on both sides in the X direction and edges above in the Z direction.

The guide mechanism 660 is matched with the first guide groove 260 and the second guide groove 460, so that the moving end 622 can move according to a guide path formed by the first guide groove 260 and the second guide groove 460 when moving, the moving end cannot move randomly, the attractiveness is improved, the service life of a product can be prolonged, meanwhile, the path of the moving end 622 is limited, the gap between the curtain 600 and the target window 003 can be prevented from being changed randomly, the shading effect of the curtain 600 is guaranteed, and the curtain 600 can reach the preset energy-saving efficiency.

In some embodiments, guide mechanism 660 may include a first guide wheel 661 and a second guide wheel 662. The first guide wheel 661 is rotatably connected to the movable end 622 and abuts against the first guide groove 260 of the fixed frame 200. The second guide wheel 662 may be rotatably coupled to the moving end 622 and abut against the second guide groove 460 of the movable frame 400.

In some embodiments, the guide mechanism 660 may be a guide slide. Both sides of the guide slider abut against the first guide groove 260 and the second guide groove 460, respectively.

In some embodiments, the window covering 001 further comprises a drive mechanism 900. The transmission 900 may be mounted directly or indirectly on the stationary surface 004. The driving mechanism 900 may be coupled to the fixed end 621 and is operable to move the movable end 622 between the first position and the second position under an external force to change an area of the target window 003 covered by the curtain 600. The external force may be manual or electric, such as a drive motor.

In some embodiments, the transmission structure 900 may include a spool. The reel may be coupled to the fixed end 621. When the spool rotates in the first direction, the curtain 600 is wound around the spool, and the moving end 622 moves in a direction close to the first position to reduce the shielding area of the target window 003, and when the spool rotates in the second direction, the curtain 600 is unwound from the spool, and the moving end 622 moves in a direction close to the second position to increase the shielding area of the target window 003. Wherein the second direction is opposite to the first direction.

In some embodiments, the drive structure 900 may also be other structures, such as a moving structure, to fold or unfold the curtain 600. In some embodiments, the window covering 001 may further include a driving mechanism coupled to the transmission mechanism 900 to provide a driving force to the transmission mechanism 900. In some embodiments, the window covering 001 may further include a control device coupled to the drive mechanism to control the drive force of the drive mechanism.

In summary, the sealable window shade 001 provided by the present specification is provided with a fixed frame 200 and a movable frame 400 opposite to each other on both sides of a curtain 600, wherein the fixed frame 200 surrounds the target window 003 and is fixedly mounted on the fixed surface 004 around the target window 003, and the movable frame 400 is movable relative to the fixed frame 200, thereby varying the distance from the fixed frame 200, when the curtain 600 reaches the second position, completely obstructing the target window 003, the movable frame 400 approaches the fixed frame 200, and is closed with respect to the fixed frame 200, the fixed frame 200 and the movable frame 400 clamp the curtain 600, a sealed connection is formed between the fixed frame 200, the curtain 600, and the movable frame 400, thereby isolating the air on both sides of the curtain 200 and preventing the air on both sides of the curtain 200 from heat exchange, thereby improving the shading and heat insulating effects of the curtain 004 and improving the energy saving effect. Therefore, the curtain and the target window are in sealing connection, a gap between the curtain and the target window is eliminated, air between two surfaces of the curtain in the target window cannot circulate through the gap between the curtain and the target window, and meanwhile sunlight cannot penetrate through the curtain through the gap between the curtain and the target window, so that the shading and heat insulation effects of the curtain are improved, the energy-saving effect is improved, the use of an air conditioner is reduced in summer, the refrigeration energy is effectively saved, and the heating cost is saved in winter. Meanwhile, the elimination of the gap between the curtain and the target window can prevent mosquitoes, dust, impurities and the like from entering the room through the gap between the curtain and the target window, so that the cleanliness of the indoor environment is improved. The sealable curtain provided by the specification is simple in structure, strong in sealing performance and good in energy-saving effect.
