Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a concealed ceiling ambient light and vehicle. Background Technology

[0002] With the widespread adoption of cars in recent years, the demand for quality details in automobiles has also increased. Interior and exterior trim components, being the first thing users notice, are particularly important. Ambient lighting, as a key feature for enhancing quality, is not only installed on the dashboard, door panels, and seats, but is also gaining increasing attention in the headliner area.

[0003] Common types of ambient headlights include direct-light and reflective types. Direct-light ambient lights are installed on the exterior surface of the headlights, and the light shines directly out through the lampshade (the human eye sees the light shining directly from the ambient light). Typical models are the Toyota Alphard and Audi A8 currently on the market. Reflective ambient lights are installed on the exterior surface of the headlights, and the ambient lights are hidden inside the trim strip. There is a certain gap between the trim strip and the headlights, and the light shines onto the headlight surface through the gap (the human eye sees the light reflected from the headlight surface). A typical model is the Buick GL8 currently on the market.

[0004] Both of the above-mentioned common ceiling ambient lighting solutions are installed on the exterior surface of the ceiling, which is not simple in design. Moreover, when the ambient lights are not lit, they look like additional parts on the ceiling, which cannot keep the ceiling surface clean and simple. Passengers can still identify the location of the ambient lights through the ceiling accessories, and the ambient lights cannot be completely hidden. Summary of the Invention

[0005] The purpose of this invention is to provide a concealed ceiling ambient light and vehicle, which completely hides the ambient light behind the exterior surface of the ceiling. When the ambient light is not lit, there are no visible additional parts on the ceiling, which can keep the exterior surface of the ceiling clean and simple, and achieve complete concealment of the ambient light.

[0006] In a first aspect, the present invention proposes a concealed ceiling ambient light, wherein the ceiling includes a ceiling surface layer and a ceiling frame, the front of the ceiling surface layer is the exterior surface of the ceiling, and the back of the ceiling surface layer is fitted and connected to the front of the ceiling frame; a light groove is formed on the ceiling frame; the ceiling ambient light includes:

[0007] Ambient lighting frame, installed on the ceiling frame;

[0008] A light-emitting component includes a light guide and a lamp holder disposed at one end of the light guide; the light guide is embedded in the lamp groove, and the lamp holder is located on the back of the ceiling frame; and

[0009] A fixing clip connects the light guide and the ambient light frame.

[0010] Furthermore, the fixing clip includes a fixing clip and a clip mounting base that engage with each other; the clip mounting base is part of the ambient light frame; one end of the fixing clip engages with the light guide, and the other end of the fixing clip engages with the clip mounting base.

[0011] Furthermore, the fixing clip includes a first clip connector, a second clip connector, and a connecting portion connecting the first clip connector and the second clip connector; the first clip connector engages with the light guide, and the second clip connector engages with the clip mounting base.

[0012] Furthermore, the second snap-fit ​​connector includes an elastic connector, two pressing parts, and two anti-disengagement hook parts; the two pressing parts are spaced apart and arranged opposite each other, and the two pressing parts are provided with two anti-disengagement hook parts corresponding to each other at their opposite ends, and the two pressing parts are connected by the elastic connector; the snap-fit ​​mounting base has a mounting cavity and a through hole with a diameter smaller than the mounting cavity communicating with the mounting cavity, and the two pressing parts are pressed against each other to realize that the anti-disengagement hook parts pass through the through hole and snap into the mounting cavity or disengage from the mounting cavity.

[0013] Furthermore, each of the two pressing parts has a corresponding snap-fit ​​groove at its opposite ends, and the snap-fit ​​groove is located above the anti-detachment hook part.

[0014] Furthermore, the two anti-detachment hooks have chamfered edges on their opposite sides below.

[0015] With the chamfered corner as a guide, it is easier for the anti-detachment hook to pass through the through hole and snap into the mounting cavity, making installation convenient.

[0016] Furthermore, the first card connector includes an elastic card portion, which is a U-shaped structure or an open ring structure.

[0017] Furthermore, the ambient light frame is provided with multiple overflow holes, and the overflow holes and both ends of the ambient light frame located at the overflow holes are filled with hot melt adhesive. The ambient light frame is bonded to the ceiling frame by hot melt adhesive.

[0018] After the hot melt adhesive cures, part of it is located between the ambient light frame and the ceiling frame, and part of it is located on the end face of the ambient light frame facing away from the ceiling frame. This creates a mushroom-shaped structure after the hot melt adhesive cures, which can increase the bonding strength between the ambient light frame and the ceiling frame.

[0019] Furthermore, a positioning and reinforcing flange is provided on one side of the ambient light frame; the positioning and reinforcing flange is closely attached to the side wall of the light trough.

[0020] The reinforced flange serves two purposes: firstly, it fits snugly against one side of the light trough in the ceiling frame, providing a positioning function; secondly, it enhances the overall strength of the ambient light frame.

[0021] Furthermore, the ambient light frame is provided with reinforcing ribs, the length direction of which is parallel to the length direction of the light groove. Multiple clip mounting seats are provided on the reinforcing ribs along their length direction. During use, the number of fixing clips can be increased or decreased as needed according to the actual fixing firmness.

[0022] Secondly, the present invention also proposes a vehicle including a roof and a concealed roof ambient light according to the above-mentioned technical solution.

[0023] The beneficial effects of the technical solution provided by this invention include: by opening a light groove on the ceiling frame on the back of the ceiling surface, the light guide of the light-emitting component is embedded in the light groove, and the ambient light frame set on the ceiling frame is used in conjunction with the fixing clips to achieve the hidden installation of the light-emitting component on the ceiling. This does not change the structure of the ceiling surface, and the appearance of the ceiling is not affected in any way. When the ambient light is not lit, there are no visible additional parts on the appearance of the ceiling, which can keep the appearance of the ceiling clean and simple. When the ambient light is lit, the light shines through the ceiling surface, resulting in a better visual effect. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1-7 As shown, this invention proposes a concealed ceiling ambient light, wherein the ceiling 3 includes a ceiling surface layer 31 and a ceiling frame 32. The front of the ceiling surface layer 31 is the exterior surface of the ceiling 3, and the back of the ceiling surface layer 31 is fitted and connected to the front of the ceiling frame 32. A light groove 320 is formed on the ceiling frame 32. The size and path of the light groove 320 are designed according to the design route of the ceiling ambient light 10.

[0035] The ceiling 3 is a multi-layer composite molding process. The ceiling surface layer 31 consists of a fabric decorative surface and a foamed softening layer. Both the fabric decorative surface and the foamed softening layer have a large number of pores, providing excellent breathability and light transmission. The ceiling frame 32 is grooved by waterjet cutting to form light troughs 320. The depth of the light troughs 320 is the thickness of the ceiling frame 32, thus the bottom of the light troughs 320 forms the ceiling surface layer 31.

[0036] The ceiling ambient light 10 includes: an ambient light frame 2, a light-emitting component, and a fixing clip.

[0037] The ambient light frame 2 is attached to the ceiling frame 32; specifically, the ambient light frame 2 is attached to the back of the ceiling frame 32, that is, the ambient light frame 2 is installed on the side of the ceiling frame 32 that is away from the ceiling surface layer 31.

[0038] The light-emitting component includes a light guide 4 and a lamp holder 5 disposed at the end of the light guide 4; the light guide 4 is embedded in the lamp groove 320, and the lamp holder 5 is located on the back of the ceiling frame 32. The lamp holder 5 may also be embedded in the lamp groove 320.

[0039] The light-emitting component in this embodiment includes a light guide 4 and lamp heads 5 disposed at both ends of the light guide 4. The light 41 emitted by the lamp heads 5 at both ends is evenly diffused along the entire light guide 4. The light 41 emitted by the light guide 4 located in the lamp groove 320 is diffused through the ceiling surface layer 31 and reaches the front of the ceiling surface layer 31, i.e., the exterior surface of the ceiling 3, which will emit light and be seen by the human eye. The trajectory of the light emission is related to the embedding path of the light guide 4, and the length of the light emission is related to the length of the light guide 4. The light emission pattern can also be designed according to the number of light guides 4 and the bending path.

[0040] A fixing clip connects the light guide 4 and the ambient light frame 2. After the light guide 4 is embedded in the light groove 320, it needs to be fixed and limited in the light groove 320 to maintain its designed path. Therefore, a fixing clip is used to connect the light guide 4 to the ambient light frame 2 to keep the shape of the light guide 4 as designed.

[0041] The fixing clip includes a fixing clip 1 and a clip mounting base 21 that engage with each other; the clip mounting base 21 is part of the ambient light frame 2; one end of the fixing clip 1 engages with the light guide 4, and the other end of the fixing clip 1 engages with the clip mounting base 21.

[0042] Specifically, the fixing clip 1 includes a first clip connector 11, a second clip connector, and a connecting part 12 connecting the first clip connector 11 and the second clip connector; the first clip connector 11 is engaged with the light guide 4, and the second clip connector is engaged with the clip mounting base 21.

[0043] The first snap-fit ​​connector 11 includes a resilient snap-fit ​​portion, which is a U-shaped structure or an open annular structure. The resilient snap-fit ​​portion has an opening and snaps onto the light guide 4 through this opening. When the light guide 4 is in the lamp slot 320, the resilient snap-fit ​​portion snaps onto the area of ​​the light guide 4 near the outside of the lamp slot 320, preventing the light guide 4 from detaching from the lamp slot 320. The opening of the resilient snap-fit ​​portion prevents the light guide 4 from being completely surrounded, especially the portion of the light guide 4 facing the ceiling surface layer 31, which directly faces the opening of the resilient snap-fit ​​portion, allowing the light 41 of the light guide 4 to pass through the ceiling surface layer 31 through the opening, ensuring the continuity of the light 41.

[0044] The second snap-fit ​​connector includes an elastic connector 15, two pressing parts 13, and two anti-disengagement hook parts 14. The two pressing parts 13 are spaced apart and arranged opposite each other. The opposite ends of the two pressing parts 13 are provided with two anti-disengagement hook parts 14. The two pressing parts 13 are connected by the elastic connector 15. The snap-fit ​​mounting base 21 has a mounting cavity and a through hole with a diameter smaller than the mounting cavity that communicates with the mounting cavity. The two pressing parts 13 are pressed against each other to make the anti-disengagement hook parts 14 pass through the through hole and snap into the mounting cavity or disengage from the mounting cavity.

[0045] The flexible connector 15 is also a U-shaped structure, and the flexible connector 15 is also connected to the connecting part 12.

[0046] The top or upper end of the clip mounting base 21 has a through hole. The clip mounting base 21 is a shell structure with an internal cavity. Its internal space constitutes the mounting cavity of the clip mounting base 21. The diameter of the through hole is smaller than the inner diameter of the mounting cavity, so that after the anti-disengagement part 14 passes through the through hole, it can enter the larger mounting cavity. Since the anti-disengagement part 14 needs to be deformed by compression in opposite directions before it can pass through the through hole, after passing through the through hole, the anti-disengagement part 14 is no longer constrained by the hole wall of the through hole. Under the elastic reset action of the elastic connector 15, the anti-disengagement part 14 unfolds and returns to the state before deformation. The anti-disengagement part 14 is laterally embedded in the mounting cavity.

[0047] The pressing part 13 not only functions to compress the elastic connector 15 to deform it and bring the anti-disengagement parts 14 closer together, but also facilitates pressing the anti-disengagement parts 14 downwards, allowing them to pass through the through hole of the clip mounting base 21 and enter the mounting cavity of the clip mounting base 21, thus installing the second clip connector onto the clip mounting base 21. Alternatively, the operation can involve compressing the anti-disengagement parts 14 to bring them closer together and then pulling them upwards to remove them from the mounting cavity, thus separating the second clip connector from the clip mounting base 21.

[0048] To ensure a tighter connection between the second snap-fit ​​connector and the clip mounting base 21, each of the two opposing ends of the pressing parts 13 is provided with a transverse snap-fit ​​groove, located above the anti-disengagement hook part 14. When the anti-disengagement hook part 14 passes through the through hole of the clip mounting base 21, the anti-disengagement hook part 14 deforms and resets, at which point the wall of the through hole of the clip mounting base 21 is precisely engaged in the snap-fit ​​groove, restricting the vertical displacement of the second snap-fit ​​connector and the clip mounting base 21.

[0049] The two anti-detachment hooks 14 have chamfered edges on their opposite sides at the bottom. The chamfers guide the anti-detachment hooks 14 to pass through the through holes and engage with the mounting cavity, making installation easier.

[0050] The ambient light frame 2 is provided with reinforcing ribs, which are located on the back side of the ambient light frame 2, i.e., the end face opposite to the ceiling frame 32. The length direction of the reinforcing ribs is parallel to the length direction of the light groove 320. Multiple clip mounting seats are provided along the length direction of the reinforcing ribs, and the number of fixing clips can be increased or decreased as needed according to the actual fixing firmness. The clip mounting seats 21 of the fixing clips are fixedly connected to the reinforcing ribs.

[0051] The ambient light frame 2 has multiple overflow holes 22. Hot melt adhesive 24 is filled into the overflow holes 22 and at both ends of the ambient light frame 2. The hot melt adhesive 24 is bonded to the ceiling frame 32. After curing, a portion of the hot melt adhesive 24 is located between the ambient light frame 2 and the ceiling frame 32, and another portion is located on the end face of the ambient light frame 2 facing away from the ceiling frame 32, forming a mushroom-shaped structure after curing. This increases the bonding strength between the ambient light frame 2 and the ceiling frame 32.

[0052] The diameter of the overflow hole 22 on the back of the ambient light frame 2 is larger than that on the front of the ambient light frame 2. When hot melt adhesive 24 is filled into the overflow hole 22, some of the hot melt adhesive 24 seeps into the space between the ambient light frame 2 and the ceiling frame 32. As the hot melt adhesive 24 is filled, some of the hot melt adhesive 24 overflows from the overflow hole 22 to the back of the ambient light frame 2, forming a mushroom-shaped structure that increases the bonding strength between the ambient light frame 2 and the ceiling frame 32.

[0053] It should be noted that the ambient light frame 2 in this embodiment has multiple overflow holes 22 spaced along its length. When installing the ambient light frame 2 on the ceiling frame 32, it is not necessary to fill each overflow hole 22 with hot melt adhesive 24. In other words, not every overflow hole 22 is filled with hot melt adhesive 24.

[0054] The ambient light frame 2 has a positioning and reinforcing flange 23 on one side; the positioning and reinforcing flange 23 is in close contact with the side wall of the light groove 320. The positioning and reinforcing flange 23 serves a positioning function by being in close contact with one side of the light groove 320 of the ceiling frame 32, and also improves the overall strength of the ambient light frame 2.

[0055] After the first connector 11 is snapped into place with the light guide 4, the first connector 11 is also pressed against the positioning and reinforcing flange 23. The positioning and reinforcing flange 23 provides positioning and support for the first connector 11, ensuring a stable connection between the first connector 11 and the light guide 4.

[0056] By creating a light groove 320 on the ceiling frame 32 on the back of the ceiling surface layer 31, the light guide 4 of the light-emitting component is embedded in the light groove 320. The ambient light frame 2 set on the ceiling frame 32, together with the fixing clips, achieves the hidden installation of the light-emitting component on the ceiling 3. The structure of the ceiling surface layer 31 is not changed, and the appearance of the ceiling 3 is not affected in any way. When the ambient light is not lit, there are no visible additional parts on the appearance of the ceiling 3, which can keep the appearance of the ceiling 3 clean and simple. When the ambient light is lit, the light 41 shines through the ceiling surface layer 31, resulting in a better visual effect.

[0057] The ceiling ambient light 10 of the present invention has a very simple structure and a high degree of design freedom. The ceiling ambient light 10 can be installed as long as there is enough space.

[0058] The number and spacing of the clip mounting seats 21 on the ambient light frame 2 of the present invention can be fixed, while the fixing clips 1 can be standardized parts, and the number of fixing clips 1 that cooperate with the ambient light frame 2 can be increased or decreased according to actual needs. In actual use, the clip mounting seats 21 on the ambient light frame 2 can be redundantly designed, and the number and position of the fixing clips 1 can be appropriately increased or decreased and adjusted according to the actual assembly strength.

[0059] Existing ambient lighting technologies generally require special design of the exterior surface of the headliner 3, which necessitates two design styles for the vehicle's headliner 3: one style for a headliner 3 without ambient lighting and another style for a headliner 3 with ambient lighting. However, the headliner ambient light 10 of this invention only requires the installation of the light-emitting component after corresponding slots are cut into the headliner frame 32 to form a light groove 320. This allows for the development of only one headliner 3 style, significantly reducing the development cost of the headliner 3.

[0060] Secondly, such as Figure 1 As shown, the present invention also proposes a vehicle, including a roof 3 and a concealed roof ambient light 10 of the above-mentioned technical solution disposed on the roof 3. Specifically, the roof 3 includes a roof surface layer 31 and a roof frame 32. The front of the roof surface layer 31 is the exterior surface of the roof 3, and the back of the roof surface layer 31 is fitted and connected to the front of the roof frame 32. A light groove 320 is provided on the roof frame 32. The concealed roof ambient light 10 includes an ambient light frame 2, a light-emitting component, and a fixing clip.

[0061] The ambient light frame 2 is installed on the ceiling frame 32.

[0062] The light-emitting component includes a light guide 4 and a lamp head 5 disposed at the end of the light guide 4; the light guide 4 is embedded in the lamp groove 320, and the lamp head 5 is located on the back side of the ceiling surface layer 31.

[0063] The fixing clip connects the light guide 4 and the ambient light frame 2.

[0064] The fixing clip includes a fixing clip 1 and a clip mounting base 21 that engage with each other; the clip mounting base 21 is part of the ambient light frame 2; one end of the fixing clip 1 engages with the light guide 4, and the other end of the fixing clip 1 engages with the clip mounting base 21.

[0065] The fixing clip 1 includes a first clip connector 11, a second clip connector, and a connecting part 12 connecting the first clip connector 11 and the second clip connector; the first clip connector 11 is engaged with the light guide 4, and the second clip connector is engaged with the clip mounting base 21.

[0066] The first snap-fit ​​connector 11 includes an elastic snap-fit ​​portion, which is a U-shaped structure or an open ring structure.

[0067] The second snap-fit ​​connector includes an elastic connector 15, two pressing parts 13, and two anti-disengagement hook parts 14. The two pressing parts 13 are spaced apart and arranged opposite each other. The opposite ends of the two pressing parts 13 are provided with two anti-disengagement hook parts 14. The two pressing parts 13 are connected by the elastic connector 15. The snap-fit ​​mounting base 21 has a mounting cavity and a through hole with a diameter smaller than the mounting cavity that communicates with the mounting cavity. The two pressing parts 13 are pressed against each other to make the anti-disengagement hook parts 14 pass through the through hole and snap into the mounting cavity or disengage from the mounting cavity.

[0068] Each of the two pressing parts 13 has a corresponding snap-fit ​​groove at its opposite ends, and the snap-fit ​​groove is located above the anti-detachment hook part 14.

[0069] The ambient light frame 2 is provided with a plurality of overflow holes 22. The overflow holes 22 and the two ends of the ambient light frame 2 located at the overflow holes 22 are filled with hot melt adhesive 24. The ambient light frame 2 and the ceiling frame 32 are bonded together by hot melt adhesive 24.

[0070] The ambient light frame 2 has a positioning and reinforcing flange 23 on one side; the positioning and reinforcing flange 23 is in close contact with the side wall of the light groove 320.

[0071] The ambient light frame 2 is provided with reinforcing ribs, the length direction of which is parallel to the length direction of the light groove 320, and a plurality of clip fixing seats are provided on the reinforcing ribs along their length direction.

[0072] The ceiling ambient light 10 of the present invention has a very simple structure and a high degree of design freedom. The ceiling ambient light 10 can be installed as long as there is enough space.

[0073] The number and spacing of the clip mounting seats 21 on the ambient light frame 2 of the present invention can be fixed, while the fixing clips 1 can be standardized parts, and the number of fixing clips 1 that cooperate with the ambient light frame 2 can be increased or decreased according to actual needs. In actual use, the clip mounting seats 21 on the ambient light frame 2 can be redundantly designed, and the number and position of the fixing clips 1 can be appropriately increased or decreased and adjusted according to the actual assembly strength.

[0074] Existing ambient lighting technologies generally require special design of the exterior surface of the headliner 3, which necessitates two design styles for the vehicle's headliner 3: one style for a headliner 3 without ambient lighting and another style for a headliner 3 with ambient lighting. However, the headliner ambient light 10 of this invention only requires the installation of the light-emitting component after corresponding slots are cut into the headliner frame 32 to form a light groove 320. This allows for the development of only one headliner 3 style, significantly reducing the development cost of the headliner 3.
