[0036] Figure 1 This is a schematic diagram of the structure of a curtain according to an embodiment. A curtain 1 includes: a roller 10, a support 20, a curtain body 30, and a horizontal rod 40. The roller 10 is mounted on the support 20. A first side 301 of the curtain body 30 is connected to the roller 10, and an opposite second side 302 is connected to the horizontal rod 40. Rotating the roller 10 causes the curtain body 30 to roll up / unroll. The horizontal rod 40 is connected to the curtain body 30 and moves in unison with it. A reinforcing structural layer 50 is provided on one side of the curtain body 30. The reinforcing structural layer 50 includes a plurality of continuously connected reinforcing units 501.

[0037] To explain further, Figure 2 This is a schematic diagram of the shape of the reinforcing structure layer in an embodiment. Figure 3 This is a schematic diagram illustrating the connection between the reinforcing structural layer and the curtain body in an embodiment. The reinforcing structural layer 50 includes a plurality of continuously connected reinforcing units 501.

The extension direction of the reinforcing unit 501 is consistent with the axis direction 100 of the roller.

[0038] Further, the reinforcing structure layer 50 formed by linearly connecting the corner plate structures 5011 in one side of the curtain body 30 of the curtain 1 can enhance the bending resistance of the surface of the curtain body 30. The top corner edges 5012 of the corner plate structures 5011 have good straightness and bending resistance. The reinforcing structure layer 50 formed by the corner plate structures 5011 can enhance the bending resistance in the extending direction of the corner plate structures 5011, and the continuous corner plate structures 5011 can be rolled in the direction perpendicular to the extending direction of the structures. The corner plate structures 5011 arranged on the surface of the curtain body 30 can greatly enhance the bending resistance of the curtain 1 while ensuring the rolling of the curtain 1, thereby improving the flatness of the curtain 1 and effectively solving the problem of bending deformation of the curtain body surface after rolling.

[0039] Further, the horizontal rod 40 has the functions of decoration and counterweight, and its shape is not unique. The cross section of the horizontal rod 40 can be trapezoidal, rectangular or circular. The material of the horizontal rod 40 can be metal such as iron and stainless steel, or plastic, glass fiber, etc. The two ends of the horizontal rod 40 can be provided with end caps for beautification. The end caps can be provided with small steps for limiting the surface of the rolled curtain body 30 and shielding the gap. The connection between the roller 10, the horizontal rod 40 and the curtain body 30 can be any one of bonding, pressing, buckling, etc.

[0040] Preferably, Figure 4 The corner plate structure side plate connection diagram of the embodiment is shown in FIG. 6. In any two adjacent corner plate structures 5011, the two side plates 5013 close to each other are connected.

[0041] Further, the two side plates 5013 can keep the corner plate structure 5011 stable relative to the surface of the curtain body 30, avoid the shaking of the two side plates 5013 of the corner plate structure 5011, keep the angle of the corner plate structure 5011 stable, thereby improving the stability of the corner plate structure 5011 and ensuring the straightness and bending resistance of the top corner edges 5012, i.e. the flatness of the surface of the curtain body 30 in the direction of the top corner edges 5012.

[0042] Further, in any two adjacent corner plate structures 5011, the two side plates 5013 close to each other form a reverse corner plate structure 5014 (part in the dashed box in FIG. 6). Figure 4

[0043] ​Further explanation, the reverse angle plate structure 5014 matches the angle plate structure 5011 can further improve the support stability, the reverse angle plate structure 5014 and the curtain body 30 surface combination constitutes a triangular stable structure, can better improve the stability of the angle plate structure 5011, keep the angle of the angle plate structure 5011 stable, guarantee the straightness and bending resistance of the top corner edge 5012, avoid the angle plate structure 5011 relative to the curtain body 30 surface shaking, guarantee the connection stability of the angle plate structure 5011 and the curtain body 30 surface, avoid the top corner edge 5012 and the curtain body 30 surface separation due to the angle plate structure 5011 shaking, twisting, so as to keep the curtain body 30 surface has long-term stable flatness under the action of the top corner edge 5012.

[0044] Further, Figure 5 The relationship between the top corner edge of the reinforcing structure layer of the embodiment and the direction of the shaft axis is shown in the schematic view, the top corner edges 5012 of all the angle plate structures are parallel to each other and consistent with the direction of the shaft axis 100 (the direction shown by the arrow 100). Figure 5

[0045] Further explanation, the top corner edges 5012 of the angle plate structure 5011 are parallel to each other, which is beneficial to provide a more uniform support force, ensure the effective connection between the reinforcing structure layer 50 and the surface of the curtain body 30, and maintain the flatness of the surface of the curtain body 30. For the window curtain, it is beneficial to uniformly wind and store, and avoid excessive local bending to form creases.

[0046] Further, Figure 6 The schematic view of the side plate size and the top corner angle of the angle plate structure of the embodiment. The wall width of one side plate of the angle plate structure 5011 is denoted as D, the wall width of the other side plate is denoted as d, and the top corner angle of the angle plate structure is θ.

[0047] The wall width of the two side plates of the angle plate structure 5011 can be directly set to be equal, that is, D=d. In this way, the two side plates 5013 with equal wall width connected in series can make the angle plate structure 5011 provide balanced bending resistance, avoiding the influence of the twisting of the angle plate structure 5011 itself on the flatness of the window curtain.

[0048] Further explanation, the wall width of the two side plates of the angle plate structure 5011 described here can be that the wall width of the two side plates of all the angle plate structures 5011 on the reinforcing structure layer 50 is equal; it can also be that the wall width of the two side plates of all the angle plate structures on the reinforcing structure layer 50 is not completely equal, and only the wall width of the two side plates of the same angle plate structure on the reinforcing structure layer 50 is equal.

[0049] Further, the top corner angle θ of the angle plate structure 5011 can be set to be not greater than 120°.

[0050] ​On the basis of ensuring that the gusset structure 5011 is linearly connected with the surface of the curtain body 30, the consistency of the overall structure when it is deformed should also be ensured, so that when the top angle of the gusset structure is not greater than 120°, this requirement can be met.

[0051] Further explanation and description, a single gusset structure can be formed by bending the sheet, and the sheet is bent in one direction at a position line on the sheet, and then the sheet is bent in the opposite direction at a position line a certain distance away from the position line. Thus, the sheet is continuously and alternately bent in two opposite directions at a certain interval to form the reinforcing structure layer.

[0052] Further explanation and description, the sheet can use plastic materials such as polyethylene terephthalate (PET), polycarbonate (PC), polymethyl methacrylate (PMMA), etc. The plastic material can be cut into the size of the curtain surface after being continuously bent in a roll, and be bonded to the surface of the curtain by adhesive. It can also be a single plastic material that is continuously bent and bonded to the surface of the curtain.

[0053] Further, Figure 7 For the size relationship between the reinforcing structure layer and the curtain surface in the embodiment, the length of the reinforcing structure layer 50 is G, and the width of the reinforcing structure layer 50 is K.

[0054] The size of the reinforcing structure layer 50 is set to cover the surface area of the curtain 30, specifically, the length G of the reinforcing structure layer 50 is equal to the length of the surface of the curtain 30, and the width K of the reinforcing structure layer 50 is equal to the width of the surface of the curtain 30.

[0055] Further explanation and description, the size of the reinforcing structure layer 50 fully covers the surface of the curtain 30, which can provide more complete bending resistance support to the curtain surface and avoid local deformation of the curtain surface without covering the reinforcing structure layer.

[0056] Further explanation and description, in the case where the edges of the curtain surface are relatively flat, the length G of the reinforcing structure layer can be less than the length of the surface of the curtain 30, and the width K of the reinforcing structure layer 50 can be less than the width of the surface of the curtain 30. Such setting can reduce the weight of the curtain and more easily achieve the flatness requirement of the curtain.

[0057] Further, Figure 8 For the size of the reinforcing unit in the embodiment, the height of the reinforcing unit is h, and the thickness of the reinforcing unit is L. h can be set to 2㎜~100㎜, and L can be set to 2㎜~50㎜.

[0058] Further, the height h and thickness L of the reinforcing unit can determine the amount of material, the difficulty of molding, the bending deformation resistance of the molded reinforcing structure layer, and the size of the rolled-up curtain. Therefore, under the premise of meeting the bending resistance of the reinforcing structure layer, appropriate height and thickness can help save costs and avoid the size of the rolled-up curtain being too large, occupying too much space. When the height h of the reinforcing unit is less than 2 mm and the thickness L is less than 2 mm, the difficulty of molding the reinforcing structure layer is greatly increased, and the bending deformation resistance of the molded reinforcing structure layer is relatively small, which is not conducive to resisting the bending deformation of the curtain surface after rolling up. When the height h is greater than 100 mm and the thickness L is greater than 50 mm, the amount of material used and the size of the rolled-up curtain are greatly increased. The large amount of material used leads to the weight of the curtain being too heavy, and the large size of the rolled-up curtain is not conducive to the packaging, transportation, and installation of the curtain, and also reduces the service life of the curtain.

[0059] Further, the height h of the reinforcing unit can gradually decrease / increase along one direction, and the thickness L can gradually increase / decrease along one direction.

[0060] In addition, the height h and the thickness L of the reinforcing unit can also vary as follows: the height h changes in a trend along one direction, and the thickness L remains unchanged; the thickness L changes in a trend along one direction, and the height h remains unchanged.

[0061] Further, Figure 9 For another corner plate structure of the embodiment, two adjacent corner plate structures 5011 can also be connected by a connecting piece 601, which can be a flat panel or a curved panel. As shown in Figure 9 As shown in FIG. a, the cross-sectional shape of the connecting piece 601 can be linear; as shown in FIG. b, the cross-sectional shape of the connecting piece 601 can be arc-shaped, and of course can also be other curved shapes. Figure 9 As shown in FIG. b, the cross-sectional shape of the connecting piece 601 can be arc-shaped, and of course can also be other curved shapes.

[0062] Through the connection of the connecting piece, the corner plate structures 5011 are not isolated from each other, thereby forming a whole, and further realizing the continuity of the reinforcing structure layer, avoiding the shaking / twisting of the corner plate structure causing the separation of the reinforcing structure layer from the surface of the curtain body, and further maintaining the long-term stable connection between the surface of the curtain body and the reinforcing structure layer, and the flatness of the connection between the reinforcing structure layer and the surface of the curtain body.

[0063] Further, a protective film layer can also be provided on the side of the reinforcing structure layer away from the curtain body to cover the reinforcing structure layer. When the curtain body is rolled up or unrolled, the protective film layer is also rolled up or unrolled, which can make the rolling-up or unrolling process of the curtain body more beautiful.

[0064] Further, Figure 10Another window curtain structure is shown in the figure. On the basis of the above structure, the window curtain 1 further comprises a curtain box 70 and a side frame 80. The curtain box 70 is provided with a cavity for accommodating the roller 10, and covers the roller 10, thereby playing a role of decoration and beautifying the window curtain. The curtain box 70 is provided with an opening, so that the curtain body can be extended out of the opening when being unfolded, and can be retracted into the opening when being rolled up. The side frame 80 is located at two side edges of the curtain body 30 which are not in the direction of the roller. The side frame 80 and the curtain body 30 are connected through a guide rail 801, and the two side edges of the curtain body 30 are embedded into the guide rail 801 for fixation. In this way, the two side edges of the curtain body 30 can slide in the guide rail 801, thereby realizing the rolling up and unfolding of the curtain body.

[0065] In addition, the side frame 80 and the guide rail 801 are provided, and the curtain body 30 of the window curtain is embedded into the guide rail 801 for fixation and tensioning, which can effectively enhance the stability of the window curtain when encountering wind.

[0066] Further explanation and description, the motor can also be provided in the curtain box 70, and the motor is connected with one end of the roller. The motor provides power for the rolling up and rolling down of the whole window curtain. The roller is driven to rotate through the control of the motor, thereby realizing the control of the rolling up and rolling down of the window curtain.

[0067] The shape of the curtain box 70 can be square, circular or polygonal, and the decorative edge (cover) thereof is generally used for hidden or embedded products, and the shape thereof can be "L" shape, "T" shape or special shape. The connection between the parts in the curtain box 70 can be achieved through screws, buckles or welding.

[0068] The above is only the preferred embodiment of the present application, and it should be pointed out that the above preferred embodiment should not be regarded as a limitation of the present application. The protection scope of the present application should be defined by the scope of the claims. For ordinary skilled in the art, some improvements and refinements can be made without departing from the spirit and scope of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
