Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0044] In order to mainly solve the technical problems of sunshade sagging and heat insulation in traditional sunshade solutions, the present application provides a new double-layer sunshade structure solution for sunroofs, which can be applied to car sunroofs. The following describes them one by one through specific embodiments.

[0045] Please also read Figure 1-Figure 12 As shown, an embodiment of the present application provides a double-layer sunshade structure for a skylight, which includes a double-curtain sunshade system, a supporting frame system and a driving system. The double-curtain sunshade system is assembled on the supporting frame system and cooperates with the driving system to realize the operation of the double-curtain sunshade. The following is a detailed description of the various systems of the double-layer sunshade structure for the skylight and the relationship between the various systems.

[0046] The double curtain sunshade system comprises a superimposed composite double curtain 4, a double curtain front pull rod 3 and a recovery reel 1, the double curtain 4 comprises an upper curtain 41 and a lower curtain 42, the front end of the double curtain 4 is connected to the double curtain front pull rod 3, and the rear end is connected to and wound on the recovery reel 1;

[0047] The supporting frame system includes a double curtain guide rail 2, a double curtain guide rear beam 7 and a double curtain guide front beam 8; the double curtain guide rear beam 7 includes a side strip guide structure on both sides, and the side strip guide structures 71 on both sides of the double curtain guide rear beam 7 are used to separate the upper and lower curtains of the double-layer curtain 4, and the side strips on both sides of the double-layer curtain 4 are respectively inserted into the double curtain guide rail 2, and the double curtain guide front beam 8 can be used to be connected with the vehicle frame;

[0048] The driving system includes a driving motor 9, a traction rope (shown in the figure) and two driving slides 6. The front ends of the side strips of the double-layer curtain 4 are connected to the two driving slides 6. The two driving slides 4 are respectively connected to the double-curtain front pull rod 3. When the driving motor 9 drives the traction rope, it drives the two driving slides 6 to move in the double-curtain guide rail 2 to drive the double-layer sunshade to open and close.

[0049] The upper curtain 41 is in a naturally drooping state on the sunshade curtain support frame, and the lower curtain 42 is hung on the upper curtain 41 by sewing threads, so that the lower curtain 42 is in an overall horizontal state.

[0050] It can be seen that in this embodiment, the front end of the double-layer curtain 4 is connected to the double-layer curtain front pull rod 3, and the rear end is connected to and wound on the recovery reel 1. The upper and lower curtains are separated by the side strip guide structure 71 on both sides of the double-layer curtain guide rear beam 7 to guide the side strips on both sides of the double-layer curtain 4 to be respectively inserted into the double-layer curtain guide rail 2, and the driving system drives the double-layer sunshade to achieve the required opening and closing actions through the connection relationship between the driving slide 5 and the double-layer curtain front pull rod 3. The upper curtain 41 is in a naturally drooping state on the sunshade support frame, and the lower curtain 42 is hung on the upper curtain 41 by the suture 5. The lower curtain 42 can be brought to an overall horizontal state by adjusting the length of the suture 5.

[0051] That is to say, the embodiment of the present application provides a new double-layer sunshade structure for skylights, which can control the degree of support by adjusting the size of the upper and lower curtains and the length of the seam 5, for example, Figure 3 As shown, the upper curtain 41 can suspend the lower curtain 42 in the Z direction, and the upper curtain 41 carries the lower curtain 42 in the Z direction to form a double-layer curtain superimposed composite structure, so that the upper curtain 41 mainly supports the lower curtain 42, so that the lower curtain 42 can be maintained in a preset state, including maintaining a basic horizontal state or a required horizontal state, and controlling the overall sagging amount of the double-layer curtain 4, so that the overall horizontal state of the sunshade curtain can be effectively controlled, thereby solving the technical problem of sunshade curtain sagging in traditional solutions.

[0052] In addition, due to the composite treatment of the seam 5 between the upper curtain 41 and the lower curtain 42, the upper curtain 41 and the lower curtain 42 are equivalent to a double composite layer structure, and the lower curtain 42 can also be mainly responsible for the modeling, surface properties, and shading and heat insulation functions. That is to say, by adjusting the thickness, performance and / or texture of the upper and lower curtains themselves, the independent curtain properties abandon the requirement that the curtains take into account both performance and appearance, and provide more surface property definition options; moreover, it can also achieve the purpose of adjusting the insulation efficiency of the double-layer curtain 4 and achieving the purpose of achieving the diversity of sunshades. It can be seen that the double-layer sunshade structure for skylights provided in the embodiment of the present application can improve the application and promotion of sunshades for large-size openings.

[0053] In general, the double-layer curtain is a composite body of upper and lower curtains, the structures and properties of which are independent of each other. The upper curtain 41 is in a naturally drooping state on the sunshade support frame, and mainly plays a supporting function, while the lower curtain 42 is suspended on the upper curtain through a sewing process, and the lower curtain is ensured to be in an overall horizontal state by adjusting the length of the stitching, thereby mainly solving the problem of sagging of existing sunshades, improving the thermal insulation effect, and strengthening thermal insulation.

[0054] It should be noted that in specific applications, the support frame system can be fixed on the frame corresponding to the sunroof position of the target device (such as a car) to achieve the installation of the double-layer sunshade structure of the sunroof. There is no specific limitation. For example, the double curtain guide rail 2 can be assembled on the body frame 20 at the sunroof position of the car. Of course, the double curtain guide rail 2 can also be combined with other assembly structures, such as a double curtain guide front beam, to be installed on the body frame structure. There is no specific limitation and no detailed explanation.

[0055] In one embodiment, the width of the upper curtain fabric 41 is greater than the width of the lower curtain fabric 42, and / or the elongation of the upper curtain fabric 41 is less than the elongation of the lower curtain fabric 42. Figure 1 The width of the curtain in the Y direction is greater than the width of the lower curtain 42 by making the width of the upper curtain 41 larger than that of the lower curtain 42, so that the seam 5 can be set between the upper and lower curtains near the edge strip, thereby effectively ensuring the support for the lower curtain 42 and the overall levelness. In addition, the elongation of the curtain refers to the ratio of the maximum stretching amount that the fabric can produce under a certain tensile force to the original length. Therefore, by making the elongation of the upper curtain 41 smaller than that of the lower curtain 42, the support performance of the upper curtain 41 on the lower curtain 42 can be better, and the resistance of the upper curtain 41 is also improved, thereby increasing the life of the overall sunshade.

[0056] In one embodiment, a plurality of spaced-apart sewing threads 5 are connected between the opposite end surfaces of the upper curtain fabric 41 and the lower curtain fabric 42, that is, a plurality of spaced-apart sewing threads 5 are connected between the upper curtain fabric 41 and the lower curtain fabric 42. As an example, the lengths of the plurality of sewing threads 5 gradually shorten from the ends of the upper and lower curtain fabrics toward the middle of the curtain fabrics, and the specific details are not limited thereto.

[0057] In some embodiments, the structural form of the driving slide 6 and the connection form of the driving slide 6 with the double-layer curtain composite structure and the curtain guide rail can also be diverse, without specific limitation. One of the structural forms is shown in the accompanying drawings and will be explained below.

[0058] In one embodiment, if Figure 5-Figure 6As shown, the driving slide 6 includes a pull rod assembly portion 61, a limit slide 62, a main slide 63, an upper traction foot 64 and a lower traction foot 65; the curtain guide rail 2 includes an upper guide portion 21 and a lower guide portion 22, the upper guide portion 21 includes an upper slide foot groove 211 and an upper side strip groove 212, the lower guide portion 22 includes a lower slide foot groove 221 and a lower side strip groove 222, and the curtain pull rod 3 includes a slide foot assembly groove 31; at this time, the curtain guide rail is equivalent to a double slide groove guide rail; the guide structure 71 separates the double curtains from the recovery reel 1 and introduces them into the upper and lower side strip grooves in the curtain guide rail 2 respectively. Exemplarily, the upper side strip groove 212 and the lower side strip groove 222 corresponding to the double slide groove guide rail are staggered in the Y direction.

[0059] The two side strips of the upper curtain fabric 41 are respectively connected to the upper traction feet 64 of the two driving slides 6, and the two side strips of the lower curtain fabric 42 are respectively connected to the lower traction feet 65 of the two driving slides 6. The upper and lower traction feet of the driving slides 6 are respectively embedded in the upper side strip groove 212 and the lower side strip groove 222 of the curtain fabric guide rail 2 on the corresponding side.

[0060] The limiting slides 62 of the two driving slides 6 are respectively embedded in the upper slide grooves 211 of the two curtain guide rails 2, the main slides 63 of the two driving slides 6 are respectively embedded in the lower slide grooves 221 of the two curtain guide rails 2, and the pull rod assembly parts 61 of the two driving slides 6 are respectively embedded in the slide assembly grooves 31 of the curtain pull rod 3.

[0061] For example, Figure 1 As shown, Figure 1 Taking the direction shown in as an example, the two side edge strips of the upper curtain 41 are respectively slidably connected to the upper guide parts 21 of the two curtain guide rails 2, and the two side edge strips of the lower curtain 42 are respectively slidably connected to the lower guide parts 22 of the curtain guide rails 2, that is, the two side ends of the upper curtain 41 along the X direction of the double-layer curtain 4 are two side strips, namely the upper curtain side strips 411, and similarly, the two side ends of the lower curtain 42 along the X direction of the double-layer curtain 4 are two side strips, namely the lower curtain side strips 421, and curtain guide rails 2 are respectively arranged at the left and right ends of the double-layer curtain 4 in the Y direction, and each curtain guide rail 2 includes an upper and lower guide part, presenting a double guide part structure, so that the two side strips of the upper curtain 41 and the lower curtain 42 can be respectively slidably connected to the upper and lower guide parts of the curtain guide rails 2 at both ends.

[0062] It should be noted that there may be various structural forms in which the double-layer curtain composite structure slides on the double-curtain guide rail 2. For example, the double-curtain guide rail may be a slide rail or other guide rail forms, which are not specifically limited.

[0063] In one embodiment, if Fig. 9As shown, the curtain cloth pulling rod 3 also includes an upper curtain front end fixing part 32 and a lower curtain front end fixing part 33, the front end of the upper curtain 41 is fixedly connected to the upper curtain front end fixing part 32, and the front end of the lower curtain 42 is fixedly connected to the lower curtain front end fixing part 33.

[0064] It should be noted that in this embodiment, a specific driving slide 6 and curtain guide rail 2 and structure and connection method are provided to ensure the feasibility of the scheme. It should also be noted that the structural shapes shown in the drawings include the shapes and structural forms of the driving slide 6, the curtain guide rail 2 and the curtain pull rod 3. For example, the shapes and forms of various grooves or slides in the above components are only illustrative in this application, and there may be other corresponding deformation schemes, which are not specifically limited.

[0065] like Figure 10-12 As shown, the double curtain guide rear beam 7 includes two side strip guide structures 71, and the two side strip guide structures 71 include a cloth guide body, and one end of the cloth guide body is provided with an upper cloth guide groove 711 and a lower cloth guide groove 712; the side strip guide structures of the double curtain guide rear beam are respectively fixed to the ends of the two curtain guide rails 2, and the upper cloth guide groove 711 and the lower cloth guide groove 712 at one end are respectively arranged corresponding to the upper side strip groove 212 and the lower side strip groove 222 at the same end.

[0066] In one embodiment, the recovery reel 1 is connected between the other ends of the two cloth guide bodies, that is, one connecting end of the recovery reel 1 is fixedly connected to one cloth guide body, and the other connecting end of the recovery reel is fixedly connected to the other cloth guide body.

[0067] In this embodiment, the upper cloth guide groove 711 and the lower cloth guide groove 712 of the side strip guide structure 71 facilitate rolling the upper and lower cloth fabrics of the sunshade curtain into the recovery reel 1, playing a cloth guiding role; secondly, it can also serve as an installation structure for the recovery reel 1, which is more convenient.

[0068] As an example, the recovery reel 1 includes a spring reel, that is, the recovery reel 1 can be in the form of a spring reel, thereby effectively ensuring the stability of the sunshade when it is opened or recovered, thereby increasing the life of the sunshade.

[0069] It should be noted that, depending on the specific application scenario, the double-layer sunshade structure of the skylight in the embodiment of the present application can be set to an electric control mode and / or a manual mode. The electric control mode means that the sunshade in the double-layer sunshade structure of the skylight can be controlled to automatically open the sunshade or pull up the sunshade; the manual mode means that the sunshade in the double-layer sunshade structure of the skylight drives a motor to open the sunshade or pull up the sunshade based on the user's hand movements; as long as the corresponding structure is set, for example, a sunshade driving structure can be added to the double-layer sunshade structure of the skylight, thereby realizing the electric control mode; and / or, a manual operating end can also be set to drive the sunshade to slide, without specific limitation.

[0070] In one embodiment, a vehicle is provided, which includes the double-layer sunshade structure and control system (not shown in the figure) of any of the above embodiments, wherein the double-layer sunshade structure of the sunshade serves as a sunshade structure of the sunroof on the top of the vehicle, wherein the physical assembly relationship between the double-layer sunshade structure of the sunroof and the vehicle is not limited, for example, the double-layer sunshade structure of the sunroof can be assembled to the vehicle frame 20 through a supporting frame system to serve as a sunshade structure of the sunroof on the top of the vehicle. The control system is electrically connected to the driving motor of the double-layer sunshade structure of the sunroof, and is used to trigger instructions such as opening or closing the double-layer sunshade of the sunroof, so that the driving system responds to the instruction to realize the control of the double curtain sunshade system.

[0071] In this embodiment, a vehicle is provided, including the double-layer sunshade structure for the sunroof mentioned in the embodiment of the present application, which can ensure that the sunshade of the roof sunroof, especially the sunshade of a vehicle with a large opening size, can be kept in a basically horizontal state or a required horizontal state, and control the overall sagging amount of the double-layer curtain 4, thereby solving the technical problem of sagging of the existing sunshade for automobile sunroofs. In addition, compared with the single-layer curtain, the double-layer sunshade structure is equivalent to adding a heat insulation layer, thereby improving the overall heat insulation effect of the curtain. At the same time, the independent curtain properties abandon the requirement that the curtain should take into account both performance and appearance, provide more surface property definition options, and have high application value and practicality.

[0072] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
