Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a sunshade and a vehicle having the sunshade. Background Technology

[0002] In automobiles, some models have already begun to feature starry sky ceilings, using LEDs or light sources along with fiber optic cables to create a starry effect inside the vehicle. However, for vehicles with sunroofs, the roof consists of both the canopy and the sunroof itself. Fiber optic cables can only be inserted into the area of ​​the canopy without a sunroof, not the sunroof itself. This means the starry sky effect cannot cover the entire roof. Furthermore, for panoramic sunroofs, the main area of ​​the roof cannot be fitted with fiber optic cables, thus preventing the creation of a starry sky effect. Utility Model Content

[0003] In view of this, this application aims to provide a sunshade with a flexible light-emitting structure. After the sunshade covers the sunroof, it can present a starry sky effect through the flexible light-emitting structure, which solves the problem that the sunroof area cannot present a starry sky effect in the traditional starry sky roof technology, and solves the problem that it is difficult to install a starry sky roof on vehicles with panoramic sunroofs. At the same time, the sunshade can be rolled up smoothly, and the rolling smoothness is not affected by the setting of the light-emitting structure.

[0004] This application provides a sunshade curtain, including a sunshade curtain body, one end of which is connected to a pull rod and the other end is connected to a roller. One of the pull rod and the roller is connected to a window frame. The roller is used to cooperate with the sunshade curtain telescopic mechanism to wind the sunshade curtain body.

[0005] The sunshade curtain body is provided with a flexible light-emitting element so that it can be rolled up with the sunshade curtain body; the flexible light-emitting element includes a bendable flexible substrate and a light-emitting source material disposed on the flexible substrate;

[0008] In one possible implementation, the flexible light-emitting element is a light-emitting film or a braidable light-emitting thread; wherein,

[0009] The light-emitting film is an electroluminescent film or an OLED light-emitting film, or the light-emitting film includes a flexible substrate in the form of a film sheet and a plurality of LED beads disposed on the flexible substrate.

[0010] The light-emitting line is an electroluminescent line.

[0011] In one possible implementation, the sunshade body along the thickness direction includes a sunshade layer and an inner layer, the flexible light-emitting element is a light-emitting film and is laid between the sunshade layer and the inner layer, and one or more light-transmitting holes are formed on the inner layer to form a starry sky pattern.

[0012] In one possible implementation, the flexible light-emitting element is a light-emitting line, which is disposed on the inner surface layer of the sunshade body facing the inside of the vehicle and exposed on the inner surface layer, and the light-emitting lines are arranged to form a starry sky pattern.

[0013] In one possible implementation, the pull rod has a hollow inner cavity, and the outer wiring harness of the flexible light-emitting element is placed in the hollow inner cavity and laid out from the end of the pull rod;

[0014] Alternatively, the external wiring harness of the flexible light-emitting element is laid along the outer wall of the pull rod and extends from the end of the pull rod, and the external wiring harness is connected to the outer wall or embedded in the wire groove on the outer wall.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] In automobiles, some models have begun to incorporate starry sky headliners, using LEDs or light sources combined with optical fibers to create a starry effect inside the vehicle. However, for vehicles with sunroofs, the roof consists of both the canopy and the sunroof itself. Optical fibers can only be inserted into the area of ​​the canopy without a sunroof, not directly onto the sunroof itself. This means the starry sky effect cannot cover the entire roof. Furthermore, for panoramic sunroofs, the main area of ​​the roof cannot be fitted with optical fibers, preventing the creation of a starry sky effect. Some models have attempted to create a starry sky effect by inserting optical fibers within the sunshade covering the sunroof, but the poor flexibility and small diameter of the fibers result in a simple and limited starry sky pattern with a poor effect if only a few are used. Conversely, if a large number of optical fibers are used within the sunshade, the sunshade becomes difficult to roll up.

[0030] In view of this, please refer to the appendix. Figures 1-5 This application provides a sunshade that can be mounted on a window frame to cover a window, such as a sunroof. The sunshade includes a sunshade body 10, one end of which is connected to a pull rod 20, and the other end to a roller 30. One of the pull rod 20 or the roller 30 is connected to the window frame, thus connecting the sunshade body 10 to the window frame. When mounted on a vehicle window, the pull rod 20 is typically used to connect to the window frame and fix one end of the sunshade body 10. Of course, the pull rod 20 can be fixedly connected to the window frame or movably connected, such as through a sliding connection. The roller 30 is used to engage a sunshade telescopic mechanism to wind the sunshade body 10. The sunshade telescopic mechanism can be a manual telescopic mechanism or an automatic telescopic mechanism with a power component. The sunshade can also be applied to the window frames of other objects, such as the windows of a room. In such embodiments, the roller 30 is connected to the window frame, the pull rod 20 is not connected to the window frame, and the sunshade telescopic mechanism can be a manual extension mechanism with a pull rope connected to the roller 30.

[0031] The sunshade body 10 is equipped with flexible light-emitting elements that can be rolled up with the sunshade body 10. The flexible light-emitting elements include a bendable flexible substrate 121 and a light-emitting material 122 disposed on the flexible substrate 121. The bendable flexible substrate 121 has a flexible structure that can be bent significantly without affecting the light emission. Examples include PET (polyester film), PI (polyimide), and FPC (flexible printed circuit). Furthermore, the flexible substrate 121 can be a film or a woven or spun thread. The film-mounted flexible light-emitting elements can be laid over the entire area (whole sheet laying, multiple strips, or multiple blocks are all possible). Since it is an active light-emitting element, the light emission is uniform. Various types of starry sky patterns can be easily formed by opening holes in the sunshade body 10 (the shape of the holes is not limited), such as forming complex but aesthetically pleasing starry sky patterns, thus enhancing the starry sky effect. Furthermore, the film-shaped flexible light-emitting element is very thin, making it easy to arrange lightly inside the sunshade body 10 without thickening the sunshade body 10 or affecting the smoothness of the sunshade body 10's roll-up and retraction.

[0032] Flexible, woven or spun linear light-emitting elements can be laid out according to the design graphics, such as by weaving, knitting, or directly embroidering, to form various desired starry sky patterns on the fabric. This not only facilitates the realization of various starry sky patterns but also does not affect the smoothness of the sunshade body 10's roll-up and retraction, and can create a good starry sky effect.

[0033] That is, the flexible light-emitting element not only has a flexible structure that can roll up with the sunshade body 10 without affecting the smoothness of the rollup of the sunshade body 10, but can also be conveniently laid on the sunshade body 10 to form various starry sky patterns as required, enhancing the convenience and diversity of starry sky pattern setting, such as making it easier to form complex starry sky patterns and enhancing the starry sky effect and quality.

[0034] As can be seen, the sunshade provided in this application can create a starry sky effect through lighting by configuring flexible light-emitting components. Simultaneously, due to its flexible structure and membrane or woven thread shape, the flexible light-emitting components can roll up with the sunshade, without affecting the smoothness of its deployment and retraction. Furthermore, the flexible light-emitting components, being membrane or thread-like, can either be fully covered or arranged according to desired patterns, conveniently forming various desired starry sky patterns, enhancing the convenience and diversity of starry sky pattern setup, and improving the starry sky light and shadow effect and quality. Simply opening the sunshade to cover the sunroof and activating the light-emitting function of the flexible light-emitting components will create a starry sky ceiling in the sunroof area. This sunshade is suitable for use on panoramic sunroofs to create a starry sky ceiling on the roof, and also suitable for use on non-panoramic sunroofs in conjunction with fixed areas of the roof to create a starry sky ceiling covering the entire roof area.

[0035] The light-emitting material 122 can be a light source capable of actively emitting light, such as LED beads, phosphors that emit light when excited by an electric current, or organic materials. Therefore, the flexible light-emitting component is an actively emitting component, emitting light uniformly. It eliminates the need for multiple light sources on one side or end of the sunshade body 10, simplifying the light-emitting structure and avoiding thickening or hardening the sunshade body 10, which would affect winding and retraction. The actively emitting flexible light-emitting component, with a film-like or woven structure, improves the ease of winding the sunshade, reduces its thickness, and allows for the arrangement of complex starry sky patterns, while also emitting light uniformly. This enhances the starry sky light and shadow effect and quality from both the perspective of starry sky pattern and light emission effect.

[0036] Specifically, the flexible light-emitting element can be a light-emitting film 12 or a light-emitting line 14. For example, the light-emitting film 12 can be an EL light-emitting film (electro-luminescent film, in which phosphors such as ZnS:Cu are excited to emit light under an alternating electric field) or an OLED light-emitting film (organic light-emitting diode film, in which organic materials emit light under a direct current electric field), or the light-emitting film 12 can include a flexible substrate 121 in the form of a film and multiple lamp beads such as LED lamp beads disposed on the flexible substrate 121. The flexible substrate 121 can be PI, a high-performance high-temperature resistant engineering plastic film; it can also be PET, a common transparent plastic film; or it can be FPC, which is formed by combining PI and PET as core substrates with copper foil, adhesives and other materials.

[0037] The light-emitting line 14 is an EL light-emitting line 14, also known as a cold light lamp line or an electroluminescent lamp line. It belongs to the electroluminescent (EL) technology and has the same light-emitting principle as EL film, but its shape is linear.

[0038] When the flexible light-emitting element is a light-emitting film 12, the sunshade body 10 along the thickness direction includes a sunshade layer 11 and an inner layer 13. The light-emitting film 12 is laid between the sunshade layer 11 and the inner layer 13. One or more light-transmitting holes 101 are formed on the inner layer 13, and the one or more light-transmitting holes 101 form a starry sky pattern. The shape of the light-transmitting hole 101 is determined according to the requirements. It can be multiple holes arranged in a dispersed manner, or it can be a continuous patterned elongated hole. This article does not make a specific limitation.

[0039] The luminescent film 12 can be a single piece, laid entirely within the sunshade curtain body 10, or it can be multiple pieces or blocks, laid piece by piece or spaced apart within the sunshade curtain body 10. The luminescent film 12 can be bonded to the sunshade layer 11 and / or the inner layer 13, or it can be compositely bonded to the sunshade layer 11 and / or the inner layer 13.

[0040] The flexible light-emitting element is a light-emitting line 14. The light-emitting line 14 is disposed on the inner surface layer 13 of the sunshade body 10 facing the inside of the vehicle and is exposed on the inner surface layer 13. The light-emitting lines 14 are arranged to form a starry sky pattern, such as... Figure 3 As shown. The luminous lines 14 can be woven onto the inner layer 13 or can form an embroidered pattern on the inner layer 13. That is, the luminous lines 14 are woven or embroidered into the fabric of the inner layer 13 and form a starry sky pattern.

[0041] The sunshade curtain is also equipped with a dimming component, which can be a dimming film installed inside the sunshade curtain body 10 or a dimming controller installed outside the sunshade curtain body 10. The flexible light-emitting element is connected to the dimming component. Through the dimming component, the brightness and color of the flexible light-emitting element can be adjusted to achieve a variety of light and shadow effects. Users can select or switch light and shadow effects according to their needs.

[0042] The external wiring harness 15 of the flexible light-emitting element can extend outward from the pull rod 20, thus preventing the external wiring harness 15 from rolling up with the sunshade body 10. For example, the external wiring harness 15 is laid along the outer wall of the pull rod 20 and extends out from the end of the pull rod 20, for example, directly connected to the outer wall of the pull rod 20 or provided with a wire groove on the outer wall of the pull rod 20 for embedding the external wiring harness 15; or, the pull rod 20 has a hollow inner cavity, and the external wiring harness 15 of the flexible light-emitting element is placed in the hollow inner cavity and laid out from the end of the pull rod 20.

[0043] Furthermore, a flexible circuit board 123 (FPC) is also provided inside the sunshade body 10. The flexible light-emitting element is connected to the external circuit through the flexible circuit board 123 and the external wiring harness 15 on the flexible circuit board 123. The first end of the flexible circuit board 123 is connected to the flexible light-emitting element, and the second end is located near or connected to the pull rod 20, so that the external wiring harness 15 of the flexible circuit board 123 can be set on the pull rod 20 and extend out of the sunshade body 10 through the pull rod 20. If the light-emitting film 12 is a flexible substrate 121 combined with lamp beads, multiple lamp beads will be set; when using light-emitting lines 14, multiple light-emitting lines 14 will also be set on the sunshade body 10. The number of external wiring harnesses 15 required in both structures is relatively large. After setting the flexible circuit board 123, such as Figure 4 As shown, the external end of the light-emitting film 12 or the light-emitting line 14 can be directly connected to the flexible circuit board 123. The flexible circuit board 123 can be connected to the controller, etc. through a bundle or a small number of wires, without the need to set a large number of external wire bundles 15, which simplifies the structure and makes it easy for the external wire bundles 15 to extend outward through the pull rod 20, which is convenient for manufacturing.

[0044] The second end of the flexible circuit board 123 can be wrapped around and connected to the outer wall of the pull rod 20, and the external wiring harness 15 can be adhered to the outer wall of the pull rod 20 or extended into the hollow cavity inside the pull rod 20; or, as Figure 5As shown, the pull rod 20 has a hollow inner cavity and an opening on the outer wall that connects to the hollow inner cavity. The second end of the flexible circuit board 123 extends into the hollow inner cavity through the opening. The external wiring harness 15 is laid in the hollow inner cavity and extends out from the end of the pull rod 20 in the length direction.
