[0002] An automotive sunroof can maximally project the scenery outside the vehicle into the vehicle, enhancing the passenger experience. The sunroof sunshade structure can help passengers change the light-transmitting range of the sunroof according to their needs, making the sunroof change from fully light-transmitting to partially light-transmitting in some areas, and finally to completely non-light-transmitting.

[0003] In existing luminous sunshade devices, the sunshade is located below the light-transmitting layer of the sunroof. It will sag due to the natural extensibility of the fabric, occupying the head space of passengers. It is not only not dirt-resistant but also affects the passenger experience. In addition, for the sake of light shielding, existing sunshades mostly use dark fabrics, which have a single color and cannot meet the increasingly rich and diverse aesthetic needs, reducing the interior beauty of the vehicle. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0075] Figure 1 This is a schematic diagram of the practical luminous sunshade curtain device. In the following description, the accompanying drawings in Figure 1 are used as the reference basis for directions. The direction perpendicular to the drawing paper and facing outward is the upper direction, the direction perpendicular to the drawing paper and facing inward is the lower direction, the direction upward along the drawing paper is the front direction, the direction downward along the drawing paper is the rear direction, the direction to the right along the drawing paper is the right direction, and the direction to the left along the drawing paper is the left direction.

[0076] As Figure 1As shown in the figure, the present invention provides a light-emitting sunshade curtain device with a double-layer light-transmitting layer structure, which includes a first light-transmitting layer 11, a second light-transmitting layer 12, a light-emitting part, a frame assembly 2, a sunshade curtain assembly 3 and a driving assembly 4. Among them, the first light-transmitting layer 11 is fixedly installed on the frame assembly 2; the frame assembly 2 is arranged in an opening on the top of the vehicle, and includes two guide rails 21, and the two guide rails 21 are symmetrically arranged below the left and right sides of the first light-transmitting layer 11; the sunshade curtain assembly 3 includes a first pull rod 33, a winding drum 32 and a curtain cloth 31 connected between the first pull rod 33 and the winding drum 32, and the winding drum 32 is fixed between the two guide rails 21; the driving assembly 4 includes a driving motor 41, a gear arranged on the output shaft of the driving motor 41, two cable wires 42 engaged with the gear, and a slider 43 connected to the front end of the cable wire 42. The cable wires 42 and the slider 43 are both arranged in the guide rails 21, and the cable wires 42 can drive the slider 43 to slide in the guide rails 21, and the slider 43 is connected to one end of the first pull rod 33. When the driving motor 41 drives the gear to rotate clockwise or counterclockwise, the cable wires 42 drive the slider 43 to move towards or away from the winding drum 32, driving the curtain cloth 31 to be stored on the winding drum 32 or to be unfolded from the winding drum 32. The driving motor 41 and the winding drum 32 can be arranged on the front side or the rear side of the first light-transmitting layer 11. The first light-transmitting layer 11 and the second light-transmitting layer 12 are preferably transparent glass or plexiglass (acrylic).

[0077] The second light-transmitting layer 12 is arranged below the first light-transmitting layer 11, and there is a hollow layer 14 between the second light-transmitting layer 12 and the first light-transmitting layer 11, and the curtain cloth 31 in the sunshade curtain assembly 3 is located in the hollow layer 14. To firmly fix the second light-transmitting layer 12 and make the second light-transmitting layer 12 not hinder the normal operation of the curtain cloth 31, each of the left and right sides of the second light-transmitting layer 12 is connected to a guide rail 21, and any one of the front side and the rear side of the second light-transmitting layer 12 is connected to the first light-transmitting layer 11, and the other side has an opening for the curtain cloth 31 to enter. Specifically, the present invention arranges the driving motor 41 and the winding drum 32 on the rear side of the first light-transmitting layer 11. Correspondingly, the front side of the second light-transmitting layer 12 is connected to the first light-transmitting layer 11, and the rear side has an opening 141 as shown in Figure 7 the figure, facilitating the curtain cloth 31 to enter the hollow layer 14 from the rear to the front.

[0078] By adding the second light-transmitting layer 12 to form the hollow layer 14, the present invention can limit the natural sag of the curtain cloth 31 without affecting the normal operation of the curtain cloth 31, which not only increases the head space of the passengers, but also makes the gap between the curtain cloth 31 and the roof lining 5 of the vehicle controllable, avoiding the problems of reduced aesthetics, comfort and cleanliness caused by the sagging and exposure of the curtain cloth, and greatly improving the riding experience of the passengers.

[0079] As Figures 2 - 4As shown, in a specific embodiment of the present invention, the width of the second light-transmitting layer 12 is smaller than that of the first light-transmitting layer 11. A wrapping edge 13 formed by an encapsulation process is connected between the left side of the first light-transmitting layer 11, the left guide rail 21 on the left side, and the left side of the second light-transmitting layer 12. Similarly, a wrapping edge connects the right side of the first light-transmitting layer 11, the right guide rail 21 on the right side, and the right side of the second light-transmitting layer 12. The wrapping edge 13 is specifically made of PU polyurethane material, which can protect the light-transmitting layer and connect the light-transmitting layer with other components. The height of the hollow layer 14 can be adjusted by adjusting the encapsulation process and the structure of the guide rail 21.

[0080] As Figure 1 and Figure 2 shown, the first pull rod 33 can be a metal part or a plastic part, which includes a first fixing part 331 and a second fixing part 332 connected to each other. The first fixing part 331 is connected to the slider 43 and is located between the first light-transmitting layer 11 and the guide rail 21; the second fixing part 332 is connected to the curtain cloth 31 by stitching or bonding and is together with the curtain cloth 31 in the hollow layer 14.

[0081] As Figure 6 (a) and (b) shown, the length of the second light-transmitting layer 12 is smaller than that of the first light-transmitting layer 11. If the front side of the second light-transmitting layer 12 is close to the front side of the first light-transmitting layer 11, a wrapping edge 131 formed by an encapsulation process can be connected between them. As Figure 6 (c) shown, if the length of the second light-transmitting layer 12 is small and its front side is far from the front side of the first light-transmitting layer 11, the front side of the second light-transmitting layer 12 can be connected to the middle part of the first light-transmitting layer 11 through the wrapping edge 131.

[0082] As Figure 7 shown, when the second light-transmitting layer 12 is made of a material with a relatively large stiffness such as a tempered light-transmitting layer, its rear side does not need to be fixed and can be suspended. To reduce the weight of the second light-transmitting layer 12, the second light-transmitting layer 12 can use a plastic ABS board (organic transparent light-transmitting layer) to achieve the purpose of weight reduction. However, because the stiffness of the plastic ABS board is insufficient, there may be a risk of collapse at the suspended rear side. To solve this problem, as Figure 10 shown, the present invention preferably has a support member 15 below the opening 141 (i.e., the bottom of the rear side of the second light-transmitting layer 12). The top of the support member 15 is connected to the second light-transmitting layer 12 by bonding or PU wrapping, and its left and right sides are connected to the first light-transmitting layer 11 by bonding or PU wrapping, thereby playing a role in supporting and preventing collapse of the rear side of the second light-transmitting layer 12.

[0083] In the above embodiments, using a PU edge to fix the relative positions of the first light-transmitting layer 11 and the second light-transmitting layer 12 may make it difficult to control the height of the hollow layer 14. At the same time, it is not convenient for disassembly and maintenance in the later stage, affecting the scrap rate and increasing the process difficulty and cost. Therefore, in a preferred embodiment of the present invention, as Figure 5 shown, fasteners are connected to the left and right sides of the first light-transmitting layer 11 through edges 13 formed by the edge coating process. Specifically, the fasteners are nuts 17; one end of the guide rail 21 is connected to the left or right side of the second light-transmitting layer 12 through an edge or an adhesive 16, and the other end is provided with a screw 171. The relative positions of the first light-transmitting layer 11 and the second light-transmitting layer 12 are fixed through the fastening and detachable connection between the screw 171 and the nut 17. Specifically, the adhesive 16 is a double-sided adhesive, and those skilled in the art can also select other adhesive materials according to needs.

[0084] Similarly, as Figure 11 shown, the front side of the second light-transmitting layer 12 can be directly connected to the front side of the first light-transmitting layer 11 provided with an edge 131 formed by the edge coating process through an adhesive 161, or a screw can be connected to the front side of the second light-transmitting layer 12 through an edge, and a nut can be connected to the front side of the first light-transmitting layer 11 through an edge. Through the cooperation between the screw and the nut, the fastening and detachable connection of the first light-transmitting layer 11 and the second light-transmitting layer 12 is achieved.

[0085] Since the second light-transmitting layer 12 is sufficient to support the entire curtain cloth 31, the left and right sides of the curtain cloth 31 will not sag. Therefore, as Figure 3 shown, in the present invention, guide belts may not be provided on the left and right sides of the curtain cloth 31, and only the front and rear sides of the curtain cloth 31 can be fixed through a first pull rod 33 and a drum 32 as Figure 1 shown.

[0086] As Figure 7 and Figure 8 shown, the sunshade curtain assembly 3 further includes a connecting shaft 36 fixed to the frame assembly 2 through a support 35. The connecting shaft 36 is connected to the drum 32 through a torsion spring. The torsion spring generates a pre-tightening force, making the drum 32 have a rotational tendency to store the curtain cloth 31 on the drum 32. This helps to neatly store the curtain cloth 31 and reduce the storage space.

[0087] Furthermore, the sunshade curtain assembly 3 can be downsized by canceling the connecting shaft 36. As Figure 4 and Figure 9 shown, it is changed to provide a guide belt 34 extending along the length direction of the curtain cloth 31 on each of the left and right sides of the curtain cloth 31. The guide belt 34 is arranged in the guide rail 21 and is a coil spring with a large restoring force itself. The coil spring has a rotational tendency to store the curtain cloth 31 on the drum 32 and can play the same role as the combination of the torsion spring + the spring shaft.

[0088] As shown Figures 12 - 15 in the figure, to meet the increasingly rich and diverse personalized aesthetic needs, the light-emitting part 6 in the present invention is electrically connected to an external power supply and is arranged below the first light-transmitting layer 11. The curtain cloth 31 includes a plurality of optical fibers 8 extending along the front-back direction of the second light-transmitting layer 12. The light emitted by the light-emitting part 6 enters the optical fibers 8 through the ends of the optical fibers 8, causing the curtain cloth 31 to emit light, thereby realizing the functions of lighting and beautifying the interior environment of the vehicle.

[0089] As shown Figures 12 - 14 in the figure, the curtain cloth 31 is woven by a cross-weaving method and includes a plurality of weft threads 311 (white lines in the figure) extending along the left-right direction of the second light-transmitting layer 12 and warp threads 312 (gray lines in the figure) extending along the front-back direction of the second light-transmitting layer 12.

[0090] To conduct light and make the curtain cloth 31 emit light, the present invention replaces a plurality of warp threads 312 with optical fibers 8 (black lines in the figure). The light-emitting part 6 is specifically a light bar and a lamp socket, and the light bar is connected to the power supply through the lamp socket. The light bar and the lamp socket can be arranged on the front side or the rear side of the curtain cloth 31, so that light enters the optical fibers 8 from the front end or the rear end of the optical fibers 8.

[0091] Preferably, the light-emitting part 6 is arranged on the front side of the curtain cloth 31; the length of the optical fiber 8 is greater than the length of the warp thread 312, its rear end is flush with the rear end of the warp thread 312, and its front end is located on the front side of the front end of the warp thread 312; the curtain cloth 31 includes three areas A, B, and C arranged from front to back. Area A is closest to the light bar 62, and only optical fibers 8 are distributed therein; both optical fibers 8 and warp threads 312 are distributed in area B, and area C includes optical fibers 8, warp threads 312, and weft threads 311. Fix the front end of the optical fiber 8, and injection mold area A together with transparent plastic (such as a transparent organic light-transmitting layer / acrylic material) to form a light-transmitting part 71. Then, through an injection molding process, connect area B and the front side of area C with the light-transmitting part 71 as a whole to form a second pull rod 7. The second pull rod 7 can replace the aforementioned first pull rod 33 and is directly connected to the slider in the guide rail at both ends. It can drive the curtain cloth 31 to move back and forth under the drive of the drive assembly. The light-transmitting part 71 formed by injection molding of transparent plastic does not prevent the light emitted by the light bar 62 from entering the optical fiber 8 and can also play a role in connecting with area B and area C. As shown Figure 1 in the figure, the rear side of the curtain cloth 31 is the same as the aforementioned setting and is connected to the winding drum 32.

[0092] As shown Figure 14As shown, the front side of the second light-transmitting layer 12 is connected to the first light-transmitting layer 11 via the edging 131. The light bar 62 and the lamp holder 61 are disposed in the hollow layer 14, located at the connection between the edging 131 and the second light-transmitting layer 12. The light bar 62 extends along the width direction (i.e., the left-right direction) of the second light-transmitting layer 12, and its width is approximately the same as that of the second light-transmitting layer 12. When the second pull rod 7 is driven by the drive assembly 4 to move to the front side of the second light-transmitting layer 12, the curtain 31 is fully unfolded. At this time, the light bar 62 can be turned on by the control system. Light enters the curtain 31 through the light bar 62, the hollow layer 14, the light-transmitting portion 71, and the optical fiber 8, causing the curtain 31 to emit light.

[0093] like Figure 15 As shown, those skilled in the art can also, as needed, place the light-emitting portion 6 on the rear side of the curtain 31, so that the front end of the optical fiber 8 is flush with the front end of the warp, and its rear end is located behind the rear end of the warp 312; the three areas A, B, and C are arranged from back to front in the curtain 31, the light-emitting portion 6 is fixed on the reel 32, and then the area A and the transparent plastic are injection-molded together to form the connecting portion 72. The connecting portion 72, areas B, and areas C are all connected to the reel 32 via adhesive 162. Figure 1 As shown, in this embodiment, the front side of the curtain 31 is connected to the first pull rod 33, similar to the previous configuration. When the first pull rod 33 is driven by the drive assembly 4 to move to the front side of the second light-transmitting layer 12, the curtain 31 is fully unfolded. At this time, the light bar 63 can be turned on by the control system. Light enters the curtain 31 through the light bar 63, the connecting portion 72, and the optical fiber 8, causing the curtain 31 to emit light.

[0094] like Figure 16 As shown, those skilled in the art can also wrap an optical fiber sheath 9 on the outside of the curtain 31. The optical fiber sheath 9 is specifically made of fluoroplastic and is black in color. A plurality of notches 91 located directly below the optical fiber 8 are opened on its lower surface by mechanical wear, chemical corrosion, etc. The light in the optical fiber 8 can be refracted from the notches 91 and emitted from the lower surface of the second light-transmitting layer 12. According to the shape formed by the plurality of notches 91, a luminous pattern with better light-dark contrast is formed, thereby enhancing the visual experience of the passengers in the vehicle.

[0095] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
