Description

Technical Field

[0001] The present invention relates to the field of vehicle sunroof manufacturing, and more particularly to an ambient light device for a vehicle sunroof, a vehicle sunroof having the ambient light device, and a vehicle including the vehicle sunroof. Background Art

[0002] Many vehicles now feature sunroofs, particularly panoramic ones, to enhance riding and driving comfort. As driving needs evolve, some designs employ ambient lighting to illuminate the sunroof glass, creating specific effects and enhancing the visual experience. Alternatively, ambient lighting can be used to adjust the lighting effects within the vehicle interior.

[0003] Usually, the ambient light is fixed directly on the sunroof rail, but it has been recognized that this may cause problems such as easy falling off and abnormal noise. In some solutions, the ambient light is fixed to the mounting bracket by mechanical means such as embedding or clamping, and then the mounting bracket is connected to the sunroof glass. Figure 1A As shown, a mounting bracket 3a is provided on the sunroof glass 1a, and after the ambient light 4a (such as a light guide) is fixed to the mounting bracket 3a, part or all of the mounting bracket 3a is fixed to the sunroof glass 1a by, for example, glue or tape 5a. With this solution, since the edging material 2a (such as polyurethane PU) of the sunroof glass 1a requires a release agent during the manufacturing process of the sunroof assembly, when arranging the mounting bracket 3a, the release agent remaining on the glass surface will repel the action of the glue or tape, so it is necessary to keep a certain distance between the mounting bracket 3a and the edging material 2a, which increases the installation space on the sunroof glass 1a, and the wiring harness assembly needs to be designed and assembled separately, resulting in additional parts cost and assembly cost. Figure 1B In the solution shown, a mounting bracket 3b is designed for mounting both the ambient light 4b and the wiring harness 8b. The mounting bracket 3b is arranged below the sunshade 7b and connected to the sunroof guide rail 6b. Figure 1A Similar to the solutions in , the ambient lights in these designs can only provide indirect light, the brightness effect is much weaker than direct light, and the light uniformity is not as good as the ambient light with a scattering cover. In particular, the structure of the mounting bracket is complex and the assembly is cumbersome.

[0004] In some programs, such as Figure 1CAs shown, the mounting bracket 3c is structurally improved to not only secure the ambient light 4c but also fit closer to the edging material 2c, reducing the installation space on the sunroof glass 1c. Furthermore, an optical cover, such as a diffuser cover 9c, is provided. In this solution, the mounting bracket 3c is attached to the sunroof glass 1c using glue or tape 5c. The diffuser cover 9c is also secured to the mounting bracket 3c using glue or tape 5c, directing light through a limited light-transmitting area. However, due to its close proximity to the edging material 2c, securing the tape during assembly is difficult, resulting in a time-consuming and labor-intensive process. Figure 1D In the illustrated solution, the edging material 2d of the skylight glass 1d is directly used as a fixing component for the ambient light 4d and the scattering cover 9d, which can reduce the use of additional parts or adhesive parts. Figure 1C and Figure 1D In the solution shown, the wiring harness assembly still needs to be designed and assembled separately. In addition, the light effect guided through the diffuser is not sufficient to meet the growing needs of users. Summary of the Invention

[0005] In order to obtain an optimized structural layout and better atmosphere lighting effects, it is also expected to further improve the existing atmosphere lighting device to obtain a more reasonable structure and a simpler assembly method, so as to solve the technical problems of complex structure, high cost and difficult assembly in the existing technology.

[0036] The following describes the implementation and use of the embodiments in detail. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways to implement and use the present invention and are not intended to limit the scope of the present invention. When describing the structural positions of components, such as up, down, top, and bottom, directional references are not absolute but relative. These directional references are appropriate when the components are arranged as shown in the figures, but they will change accordingly if the positions of the components in the figures are changed.

[0037] In this article, the vehicle sunroof covers a small single-glass sunroof or a fixed panoramic sunroof, or a double-glass panoramic sunroof.

[0038] Combine Figures 2 to 4 As shown, according to the concept of the present invention, the ambient light device is fixed as an independent whole under the sunroof glass 10 of the vehicle sunroof. In this way, even if the ambient light device is adjacent to the edging material 20, the ambient light device can be easily fixed and assembled on the sunroof glass, effectively achieving a compromise between size reduction and easy installation. This fixed assembly can be achieved by bonding, for example Figure 2 The adhesive or tape 70 shown in FIG. 1 may also be combined with Figure 3 The connectors 33a and 33b at both ends of the ambient light device are assembled on the sunroof assembly 60. Figure 4 As shown, the assembly process is simplified. Figure 4 In the illustrated embodiment, the ambient light device is arranged roughly linearly along an edge of the sunroof assembly 60. In some embodiments, the ambient light device may also be arranged at intervals along an edge, or may also be arranged around each edge to present different ambient light layouts as needed.

[0039] In some embodiments, the ambient light device includes a housing 31 and a diffusion cover 32. Figure 2 Combined with Figures 5 to 8The housing 31 is provided with a first groove 311 for securing the ambient light 40 and a second groove 312 for securing the wiring harness 50, thereby advantageously integrating the ambient light 40 and the wiring harness 50. The diffuser cover 32 is connected to the housing 31, preferably detachably, to define a chamber for accommodating the ambient light 40. According to the present invention, the diffuser cover 32 is provided with a pattern, thereby providing a patterned ambient light effect. The pattern may include graphics, text, or a grid.

[0040] In some embodiments, the diffusion cover 32 may be configured to have an L-shaped, U-shaped, or T-shaped cross-sectional shape, for example Figure 2 and Figure 5 , and includes a connecting plate 321 connected to the shell 31 and a light guide plate 322 for guiding light out, wherein the pattern is provided on the light guide plate 322. In some embodiments, the scattering cover 32 may be an optical scattering sheet, for example, it may be selected as a transparent or translucent transmissive component, or may be a colorless or colored material, or may be a lens or a prism, so that the light emitted from the atmosphere lamp 40 directly achieves certain specific atmosphere lamp effects through the scattering cover 32. In some embodiments, the pattern may be a film or coating attached to or applied to the light guide plate 322, wherein the film has a printed pattern. In some embodiments, the pattern may be formed by printing or surface laser engraving the light guide plate 322. In some embodiments, such as Figure 9 As shown, the pattern can be formed by providing a plurality of hole patterns 327 on the light guide plate 322. The hole patterns 327 can be regularly or irregularly distributed and can have circular, oblong, elliptical, or polygonal shapes. In addition, the hole patterns can also have the same or different sizes.

[0041] from Figure 2 As can be seen in the figure, after the housing 31 and the diffuser cover 32 are assembled, a roughly flush mounting surface S is obtained. This mounting surface S can be bonded to the underside of the sunroof glass 10 using glue or tape. Simply bonding this mounting surface S provides a secure connection between the ambient light device and the sunroof glass 10, making operation easy. The connection structure between the housing 31 and the diffuser cover 32 will be further described below. Furthermore, the light guide plate of the diffuser cover 32 is advantageously arranged at an angle to the sunroof glass 10, thereby achieving a direct ambient light effect with uniform light and a brightness that meets user requirements.

[0042] exist Figures 5 to 8 In the embodiment shown, the housing 31 and the scattering cover 32 are detachably connected by a plurality of snap-fit ​​structures arranged at intervals along the length direction. Figure 5The housing 31 may include a main body wall 310, with a first groove 311 and a second groove 312 respectively provided on both sides of the main body wall 310. The clamping structure includes a plurality of first positioning portions and / or a plurality of first clamping portions spaced apart along one or both outer walls of the first groove 311, and a plurality of second positioning portions and / or a plurality of second clamping portions spaced apart along the connecting plate 321 of the scattering cover 32, wherein the first positioning portions and the second positioning portions cooperate with each other, and the first clamping portions and the second clamping portions cooperate with each other.

[0043] Specifically, combined Figure 5 and Figure 6 In the embodiment shown, the first positioning portion may include a protrusion 314 vertically protruding from the outer wall 3112 of the first groove 311 and / or a protrusion 315 ( Figure 10 ), the second positioning portion may include an opening 325 provided on the connecting plate 321 and / or a notch 328 facing the housing 31 ( Figure 10 The boss 314 cooperates with the opening 325 to achieve, for example, Y-direction (vehicle width direction) positioning between the housing 31 and the scattering cover 32, and the boss 315 cooperates with the notch 328 to achieve, for example, X-direction (vehicle length direction) positioning between the housing 31 and the scattering cover 32. Depending on different needs, the above positioning structures can be used separately ( Figure 5 ) or used adjacent to each other ( Figure 6 ), can also be used at intervals or staggered ( Figure 10 ).

[0044] In some embodiments, the first clamping portion includes a hook 316 protruding from the main wall 310 toward the diffusion cover 32, and the second clamping portion includes a buckle 324 provided on the connecting plate 321. Figure 5 As shown. In this way, after being positioned relative to each other by the positioning structure, the housing 31 and the scattering cover 32 can be fixed to each other by the snap-fit ​​structure. In some embodiments, the snap-fit ​​structure may further include a plurality of snap-fit ​​grooves spaced apart on one side inner wall or both sides inner wall of the first slot 311, and a plurality of clips provided along the edge of the light guide plate 322 or the edge of the connecting plate 321 of the scattering cover 32, wherein the clips cooperate with the snap-fit ​​grooves. For example, in combination with Figure 5 and Figure 6 The card slot 317 can be formed on the inner wall 3111 of one side of the first slot 311, and the card clip 323 is correspondingly formed on the edge of the light guide plate 322, so that they can be further engaged with each other to achieve fixation. Figure 5It can also be seen that the outer wall 3112 of the first groove 311 where the boss 314 is set is retracted by one end distance compared to the end face of the main wall 310, and this distance is roughly equal to the thickness of the connecting plate 321 of the scattering cover 32. Therefore, after the shell 31 and the scattering cover 32 are assembled through the positioning part and the clamping part, the above-mentioned roughly flush mounting surface can be obtained.

[0045] In some embodiments, the first groove 311 of the housing 31 may be provided with a plurality of first engaging edges extending from one inner wall toward the other inner wall, for example Figure 6 The first snap-on edge 313 shown in FIG. 3 is configured such that the opening size of the first snap-on edge 313 is smaller than that of the first slot 311, thereby preventing the ambient light 40 from accidentally falling off, thereby achieving stable and reliable installation and effectively protecting the ambient light from damage or friction damage to surrounding components during assembly. Optionally, multiple first snap-on edges 313 are arranged symmetrically or staggered on both sides of the first slot 313 along the length of the first slot 311.

[0046] Alternatively, the ambient light 40 may include a light guide or a light emitting diode (LED) strip connected to a light source. The light guide is made of a material such as polycarbonate (PC) or polymethyl methacrylate (PMMA), and is connected to a light source (such as an LED) to guide light from the light source to a desired location inside the vehicle. The LED strip can be directly powered on to emit light to produce an ambient light effect. Typically, the light guide or LED strip has a circular cross-section. However, according to the present invention, the ambient light includes but is not limited to a circular, square, rectangular or irregular cross-section. For example Figure 2 As shown in FIG, the ambient light 40 may have a substantially rectangular cross-section to obtain a larger diffusion angle and achieve a better brightness effect, and the ambient light 40 may be provided with a ridge 41 engaged with the first snap-on edge 313. Therefore, the first snap-on edge 313 may correspondingly have a linear or arcuate snap-on surface.

[0047] Similarly, the second groove 312 of the housing 31 may be provided with a plurality of second snap-fit ​​edges extending from one inner wall toward the other inner wall, for example Figure 7 The second snap-fitting edge 318 shown in FIG. 3 is formed so that the opening size at the second snap-fitting edge is smaller than the size of the second slot 312. Optionally, a plurality of second snap-fitting edges 318 are symmetrically arranged or staggered on both sides of the second slot 312 along the length direction of the second slot 312. Similarly, the second snap-fitting edge 318 can have an arcuate snap-fitting surface to securely clamp the wire harness 50, which generally has a circular cross-section.

[0048] When assembling the ambient light device, the ambient light 40 can be pressed or squeezed into the first groove 311 of the housing 31 and fixed by the first snap-fit ​​edge 313. The wiring harness 50 can then be pressed into the second groove 312 of the housing 31 and fixed by the second snap-fit ​​edge 318. The scattering cover 32 can then be placed on the outside of the ambient light 40, positioned by the positioning structure and fixed by the snap-fit ​​structure, thereby assembling the ambient light device into an integral structure. The installation is simple and convenient, and the device is easy to disassemble, saving time and cost, and improving assembly efficiency. Finally, the ambient light device only needs to be installed below the sunroof glass 10 by, for example, the tape on the mounting surface S. The overall appearance of the vehicle sunroof is compact and beautiful. When the ambient light device is needed, the light emitted from the ambient light 40 passes through the scattering cover 32, and an ambient light effect with a pattern can be derived as needed to obtain specific ambient lighting for the sunroof, roof, and / or the entire interior space of the vehicle.

[0049] It should be understood here that the embodiments shown in the figures only show the optional shapes, sizes and arrangements of the ambient light device and the vehicle sunroof with the ambient light device according to the present invention. They are only illustrative and not restrictive. Other shapes, sizes and arrangements may also be adopted without departing from the spirit and scope of the present invention.

[0050] The technical content and technical features of the present invention have been disclosed above. However, it is understood that, based on the creative ideas of the present invention, those skilled in the art may make various changes and improvements to the above-disclosed concepts, all of which fall within the scope of protection of the present invention.
