DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor also belong to the scope of protection of the present application.

[0024] One of the objectives of this invention is to provide a novel starry sky sunshade curtain to solve the problems existing in the prior art. It not only has a stronger overall structure, but also provides more stable starry sky light intensity and a higher degree of realism in simulating starry sky light.

[0025] Another objective of this invention is to propose the application of the aforementioned starry sky sunshade as a starry sky luminous structure in automobiles.

[0026] Another object of the present invention is to provide a car with the above-mentioned starry sky sunshade on the roof.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1 like Figure 1 As shown, this embodiment provides a starry sky sunshade 100, including a structural frame 1, a sunshade assembly 2, and a strip-shaped light emitter. The structural frame 1 has a central cutout to provide space for the installation and retraction of the sunshade 21. The sunshade assembly 2 includes the sunshade 21, which is positioned at the central cutout of the structural frame 1. The sunshade 21 includes a light-blocking layer 211, a light-guiding layer 212, and a light-leaking layer 213, which are sequentially stacked. The fixing methods between any two layers include, but are not limited to, bonding and sewing. The edge of the light-guiding layer 212 is exposed at the outer periphery of the sunshade 21 to receive light and guide light for illumination. The light-leaking layer 213 is made of a light-blocking material and has several light-leaking holes. These holes expose corresponding local areas of the light-guiding layer 212, allowing the light from the light-guiding layer 212 to emit starlight, creating a starry sky effect. A strip-shaped light emitter is mounted on the structural frame 1 and located on at least one side of the outer periphery of the sunshade 21. The strip-shaped light emitter is used to illuminate the edge of the sunshade 21 (i.e., the position where the edge of the light guide layer 212 is exposed) to provide a stable strip-shaped light source for the light guide layer 212. After receiving the light source, the light guide layer 212 will guide the light and illuminate, thereby achieving the aforementioned starry sky illumination effect.

[0029] The starry sky sunshade curtain 100 adopts a strip-shaped light emitter as a light source for starry sky light emission, and the light emission is more uniform and stable compared with a point-shaped light source. By embedding the light guide layer 212 in the sunshade curtain 21 and cooperating with the strip-shaped light emitter, the light guide layer 212 can conduct the light source emitted by the strip-shaped light emitter to realize starry sky light emission, has the advantage of uniform light intensity distribution, can avoid the problem of light intensity attenuation caused by the extension of the light source emission path, and further cause poor starry sky light emission effect, and can improve the authenticity of starry sky light emission simulation. Moreover, the entire starry sky sunshade curtain 100 takes a light-shielding curtain structure as a basic framework, not only realizes the functional integration of the starry sky top and the light-shielding function of the sunshade curtain, but also integrates the strip-shaped light emitter and the light guide layer 212 in the sunshade curtain structure, improves the integrity and disassembly convenience of the starry sky light emission structure, and solves the problem of poor structural integrity of the existing point-shaped light source.

[0030] In some feasible embodiments, as shown in Figure 3 The light guide layer 212 is preferably a hollow mesh structure integrally formed by using a light guide material. The shapes of the hollow holes in the structure are the same, including but not limited to triangle, rectangle, diamond, circle, etc. The light guide material used includes but is not limited to plastic optical fiber, PS (polystyrene), PC (polycarbonate), etc. The light guide layer 212 adopts an integrally formed hollow mesh structure or a strip-shaped grid structure, so that each longitudinal and transverse intersection point is an integrally formed radial structure. The entire mesh structure is longitudinally and transversely connected, which is conducive to uniform diffusion of light intensity. Even if it is partially disconnected, the light intensity of the light guide layer can still be stable and uniform.

[0031] As shown in Figure 2 The sunshade curtain 21 is a sandwich structure as a whole, and the light guide layer 212 is located at the middle layer position. The sunshade curtain 21 preferably adopts a rectangular sunshade curtain, and the edge end surface of any side of the sunshade curtain 21 fully exposes the side length of the light guide layer 212. Based on this, the outer peripheral edge end surface of the sunshade curtain 21 exposes the entire light guide layer 212, and the edge end surface of the light guide layer 212 is fully exposed, which can improve the receiving area of the light guide layer 212 for the light source and ensure the starry sky light emission effect.

[0032] In actual application, the light guide layer 212 can be provided with only one layer or a plurality of layers in succession.

[0033] The light-shielding layer 211 and the light leakage layer 213 are made of materials with good light-shielding properties, including but not limited to polyester fiber, linen / bamboo fiber, metal coated fabric, etc. The processing method of the light leakage holes on the light leakage layer 213 includes but is not limited to laser etching and punching.

The guide rail groove is preferably a U-shaped groove, and the strip-shaped light emitting device can be fixed in the guide rail groove by means of adhesion or bolt fixation. The two side edges of the sunshade curtain 21 embedded in the guide rail grooves can fully receive the light source of the strip-shaped light emitting device and avoid light leakage to affect the light emitting effect.

The curtain winding and unwinding power system 24 is used to drive the rear winding shaft 23 to rotate, so as to unfold or wind the sunshade curtain 21 onto the rear winding shaft 23. The curtain winding and unwinding power system 24 and the rear winding shaft 23 are both conventional components in the existing vehicle sunshade curtain, and belong to mature prior art, which will not be described herein.

[0041] In some possible implementation manners, in addition to the strip-shaped light emitters arranged in the two guide rails 13, the strip-shaped light emitters can also be synchronously arranged on the rear winding shaft 23 and the front pull plate 22. In this case, the strip-shaped light emitters are arranged on the four sides of the outer periphery of the sunshade curtain 21, and the length of any strip-shaped light emitter is not shorter than the length of the corresponding side of the sunshade curtain 21. Based on the structure of the strip-shaped light emitters arranged on the rear winding shaft 23 and the front pull plate 22, the lead control system 3 further includes a third wire branch 34, a fourth wire branch 35 and a fifth wire branch (not shown in the figure).

[0043] Similarly, the front pull plate 22 is provided with a mounting groove along the axial direction thereof, and the strip-shaped light emitter is embedded in the mounting groove. Meanwhile, the front end edge of the sunshade curtain 21 is embedded in the mounting groove and can be fixed in the mounting groove by interference clamping, bonding or the like, so as to fully receive the light source emitted by the strip-shaped light emitter in the front pull plate 22.
