Description

Technical Field

[0001] This application relates to the field of lighting structure technology, and in particular to a lighting structure, vehicle interior components, and vehicles. Background Technology

[0002] In modern spatial design, lighting structures are no longer limited to mere illumination; they also play a crucial role in creating ambiance and enhancing visual depth, as exemplified by ambient lighting. By simultaneously achieving direct and reflected light effects, ambient lighting balances functionality and artistry. Direct light provides a clear focal point, highlighting object outlines and enhancing the spatial depth and clarity; while reflected light, through diffuse reflection, creates a soft, uniform halo effect, reducing glare, improving comfort, and adding subtle variations in light and shadow to the space, thus elevating its overall quality.

[0003] The existing lighting structure uses brackets to fix the ambient lights, and the brackets completely cover the ambient lights. Although this achieves the direct lighting effect of the ambient lights, the brightness of the reflected light from the ambient lights is weak and cannot meet the requirements of the lighting effect. Utility Model Content

[0004] The purpose of this application is to solve the aforementioned technical problems by providing a lighting structure, automotive interior components, and a vehicle, thereby achieving both direct and reflected light effects for ambient lighting, while simultaneously enhancing the brightness of the reflected light to meet the requirements of light and shadow effects. To achieve the above objective, the technical solution of this application is as follows: In a first aspect, this application provides a lighting structure, including a lower frame, a covering, and a bracket; the covering is disposed on the top of the bracket, the lower frame is disposed on the bottom of the bracket, the covering extends toward the lower frame and forms an opening between the covering and the lower frame, the bracket is provided with a light-transmitting port and a light guide corresponding to the lower frame, the bracket includes a light-transmitting part located in the opening, the light from the light guide shines directly out of the light-transmitting part, the light from the light guide shines through the light-transmitting port to the lower frame, and is reflected out of the opening from the lower frame.

[0005] In a preferred embodiment, the bracket further includes a main body and a support. The top of the main body is connected to the covering, the bottom of the main body is connected to the lower frame, the support is disposed on the side wall of the main body and located between the main body and the covering, and the light-transmitting part is connected to the support.

[0006] In a further technical solution, the support part has a support groove, the light-transmitting opening is the groove opening of the support groove, the light-transmitting part extends along the groove wall of the support groove to the opening, and the light guide is disposed in the support groove.

[0007] In a further technical solution, the support groove wall is provided with a first positioning element, which is connected to the optical guide element.

[0008] In a preferred embodiment, the lower frame is provided with a reflective layer located below the light guide and the light-transmitting port.

[0009] In a further technical solution, the reflective layer and the lower skeleton are integrally or separately configured, and the reflective layer and / or the lower skeleton are made of thermoplastic polymer materials.

[0010] In a preferred embodiment, the bottom of the light guide is located above the bottom of the light-transmitting portion, or the bottom of the light guide is flush with the bottom of the light-transmitting portion.

[0011] In a preferred embodiment, the end face of the light-transmitting portion extending from the opening protrudes relative to the outer surface of the covering.

[0012] Secondly, this application provides an interior component for a vehicle, including the aforementioned lighting structure.

[0013] Thirdly, this application provides a vehicle including the aforementioned interior trim components.

[0014] Compared with existing technologies, the beneficial effects of this application on the lighting structure, interior components, and vehicle are mainly reflected in: The support section has a light-transmitting port, allowing light from the light guide to shine directly onto the lower frame. This avoids excessive obstruction of the light guide by the support section, increasing the brightness of the reflected light from the light guide directly onto the lower frame. Simultaneously, light from the light guide can be transmitted through the light-transmitting section, resulting in a lighting structure that combines direct and reflected light, creating a unique lighting effect with interplay of light and shadow and a blend of reality and illusion. Especially in automotive or indoor settings, this composite lighting effect not only meets practical needs but also creates an immersive and personalized atmosphere, giving the space more emotional warmth and technological aesthetics.

Detailed Implementation

[0017] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0018] Example 1 This embodiment provides a lighting structure for mounting a light guide 4, enabling the light guide 4 to achieve both direct and reflected light effects. This provides a multi-layered aesthetic appeal, adds soft light and shadow variations to the space, enhances the overall texture, and meets user needs. The lighting structure can be installed on vehicle dashboards, center consoles, armrests, door sills, etc., and is not limited to vehicles. It can also be applied to other spaces, such as outdoor mobile lighting structures, to meet the needs of controlling the lighting atmosphere of a space.

[0019] In related technologies, ambient lights can achieve both direct and reflected light effects. However, when emitting direct light, ambient lights require a support frame to achieve reflected light effects. The reflected light effect of ambient lights is weak, and the sense of depth in the light is poor, failing to meet visual aesthetic requirements. Therefore, this embodiment improves the lighting structure to address these issues, enabling the ambient light to achieve both direct and reflected light effects while enhancing the depth and brightness of the reflected light effect, creating an ambient lighting effect with alternating light and shadow, and a combination of real and virtual elements. A detailed explanation follows.

[0020] like Figures 1-4As shown, the lighting structure includes a lower frame 1, a covering 2, and a support 3. The covering 2 is located at the top of the support 3, and the lower frame 1 is located at the bottom of the support 3. Specifically, the support 3 includes a main body 31, a support 32, and a light-transmitting part 33. The covering 2 is located at the top of the main body 31, and the lower frame 1 is located at the bottom of the main body 31. The covering 2 extends toward the lower frame 1 and forms an opening 21 between it and the lower frame 1. The support 32 is located on the side wall of the main body 31 and between the main body 31 and the covering 2. The light-transmitting part 33 connects to the support 32 and is located in the opening 21.

[0021] The support 3 is provided with a light-transmitting port 36 and a light guide 4 corresponding to the lower frame 1. Specifically, the support part 32 has a support groove with the opening facing the lower frame 1. The light-transmitting port 36 can be the opening of the support groove. The light-transmitting part 33 extends along the groove wall of the support groove to the opening 21. The light guide 4 is provided in the support groove. The light from the light guide 4 shines directly out of the light-transmitting part 33. The light from the light guide 4 shines through the light-transmitting port 36 to the lower frame 1 and is reflected from the lower frame 1 to the opening 21.

[0022] The main body 31, support 32, and light-transmitting part 33 can be integrally molded, such as as a one-piece injection molded part, or they can be separately molded. The overall support 3 can be made of polycarbonate (PC) material, and the light-transmitting part 33 can also be made of PC material, which has high transparency, impact resistance, heat resistance, and flame retardancy. Therefore, the light from the light guide 4 can effectively penetrate the light-transmitting part 33, thereby forming direct light and achieving the required atmosphere of direct light effect.

[0023] The main body 31 can effectively support the covering 2, so that an opening 21 is formed between the covering 2 and the lower frame 1, so that the light-transmitting part 33 extends outward from the opening 21. Even if the light guide 4 is set in the support groove, light can be emitted from the opening 21 by the light-transmitting part 33.

[0024] One end of the covering 2 is connected to the main body 31, and the other end of the covering 2 extends downward. The covering 2 can have a roughly arc-shaped structure. The covering 2 is adapted to the structure of the bracket 3. The covering 2 can effectively block part of the light from the light guide 4, while covering the exposed parts on the bracket 3 to achieve a better appearance. A cavity is formed between the covering 2 and the main body 31. The cavity is connected to the opening 21, so that the support 32 is located in the cavity without affecting the light-transmitting part 33 extending from the cavity to the opening 21.

[0025] In this embodiment, the support part 32 has a light-transmitting port 36, so that the light from the light guide 4 can be directly projected onto the lower frame 1 through the light-transmitting port 36, avoiding excessive obstruction of the light guide 4 by the support part 32, and improving the brightness of the reflected light presented by the light directly projected onto the lower frame 1 by the light guide 4. At the same time, the light from the light guide 4 can be transmitted through the light-transmitting part 33, so that the lighting structure has both direct and reflected effects, forming a unique lighting effect of alternating light and shadow and combining reality and illusion. Especially in vehicle or indoor scenes, this composite lighting effect can not only meet practical needs, but also create an immersive and personalized atmosphere, giving the space more emotional warmth and technological beauty.

[0026] like Figure 3 As shown, in one specific embodiment, the bottom of the light guide 4 can be located above the bottom of the light-transmitting part 33, or the bottom of the light guide 4 can be flush with the bottom of the light-transmitting part 33.

[0027] The main body 31 has a roughly elongated plate structure, and the light guide 4 has a roughly tubular structure. The axial direction of the light guide 4 is consistent with the length direction of the light structure. The outer surface of the lower frame 1 is the reflecting surface of the light emitted from the light guide 4. The reflecting surface can be a flat or curved surface. The reflecting surface of the lower frame 1 is located below the light guide 4 and the light-transmitting port 36.

[0028] For example, when the reflective surface is planar, it is perpendicular to the height direction of the light structure. The distance L from the light guide 4 to the lower frame 1 is greater than or equal to the distance H from the light-transmitting part 33 to the lower frame 1. The distance L from the light guide 4 to the lower frame 1 refers to the distance from the bottom edge of the outer periphery of the light guide 4 to the reflective surface, and the distance H from the light-transmitting part 33 to the lower frame 1 refers to the distance from the bottom edge of the light-transmitting part 33 to the reflective surface. Since the distance L from the light guide 4 to the lower frame 1 is greater than or equal to the distance H from the light-transmitting part 33 to the lower frame 1, the light guide 4 is hidden behind the light-transmitting part 33 along the length direction or along the width direction of the light structure. The back edge of the light-transmitting part 33 refers to the inner surface of the light structure that is not exposed to the external space. The outer surface of the light-transmitting part 33 has a better appearance, and the light from the light guide 4 can directly shine through the light-transmitting part 33 to achieve a direct shining effect.

[0029] When the reflective surface is curved, the light from the light guide 4 shines directly onto the reflective surface, and the resulting light spot is curved and deformed, giving it a three-dimensional feel; the light is diffused at multiple angles, and the light diffuses softly, giving it a strong sense of layering.

[0030] like Figure 3 As shown, in one specific embodiment, the bottom of the covering 2 is located above the light-transmitting part 33, and a gap 22 is formed between the covering 2 and the light-transmitting part 33. The end face of the light-transmitting part 33 extending from the opening 21 protrudes relative to the outer surface of the covering 2.

[0031] A gap 22 is formed between the cover 2 and the light-transmitting part 33. This gap 22 makes it easier to assemble the bracket 3 and the cover 2, avoiding misalignment due to dimensional tolerances. The light-transmitting part 33 can effectively extend to the opening 21. At the same time, sufficient space is reserved for the support groove to prevent the cover 2 from squeezing the light guide 4 and affecting the light presentation effect.

[0032] Furthermore, the end face of the light-transmitting part 33 extending from the opening 21 protrudes relative to the outer surface of the covering part 2, so that light can be presented in the external space of the light structure through the light-transmitting part 33, avoiding the light-transmitting part 33 being recessed into the cavity and affecting the light presentation effect.

[0033] like Figure 3 , Figure 5 As shown, in one specific embodiment, the light-transmitting part 33 has a light-transmitting groove 34 with the opening facing upward, and a reinforcing rib 35 is provided inside the light-transmitting groove 34.

[0034] Since the light-transmitting part 33 is made of plastic, it has a certain thickness along the height direction of the light structure and extends an opening 21 along the width direction of the light structure. Thus, the light-transmitting part 33 can effectively block the shape of the light guide 4 along the length or width direction of the light structure. The molding process of the light-transmitting part 33 is prone to shrinkage problems. Therefore, a light-transmitting groove 34 is provided on the light-transmitting part 33 to reduce the local volume and thickness of the light-transmitting part 33. During the injection molding of the light-transmitting part 33, the cooling is faster and the shrinkage is more uniform, reducing the accumulation of internal stress. This allows the light-transmitting part 33 to be accurately molded, ensuring that the light-transmitting part 33 forms the set thickness along the height direction of the light structure.

[0035] To further enhance the structural strength of the light-transmitting part 33, multiple reinforcing ribs 35 are provided in the light-transmitting groove 34. The multiple reinforcing ribs 35 are arranged at intervals along the length of the light structure. The reinforcing ribs 35 and the light-transmitting part 33 can be integrally formed to ensure the stable forming of the light-transmitting part 33 and avoid collapse or deformation problems.

[0036] like Figure 2 , Figure 7 As shown, in one specific embodiment, the support groove wall is provided with a first positioning member 51, which is connected to the light guide member 4.

[0037] The first positioning element 51 can be a snap-fit ​​structure, a gripper structure, etc. The first positioning element 51 is provided with a downward positioning opening (not marked in the figure). The light guide 4 is embedded in the positioning opening. Specifically, the size of the positioning opening is smaller than the diameter of the light guide 4. The first positioning element 51 can be integrally formed with the support part 32. The first positioning element 51 has a certain elastic clamping force. When the light guide 4 is embedded in the first positioning element 51, the first positioning element 51 stably clamps the light guide 4, preventing the light guide 4 from falling off the first positioning element 51.

[0038] The number of first positioning elements 51 can be multiple, and multiple first positioning elements 51 are arranged at intervals in the support groove along the length direction of the light structure; the number of first positioning elements 51 is adapted to the length of the support groove along the length direction of the light structure, so as to avoid the light guide 4 being interfered with by setting too many first positioning elements 51; and to avoid the light guide 4 being not positioned stably due to setting too few first positioning elements 51.

[0039] like Figure 2 As shown, in one specific embodiment, a reflective layer 11 is provided on the outer surface of the lower skeleton 1, and the reflective layer 11 extends from the side wall of the main body 31 through an opening 21. The reflective layer 11 and / or the lower skeleton 1 are made of thermoplastic polymer material.

[0040] The reflective layer 11 serves as the reflective surface of the lower frame 1. The reflective layer 11 can be integrally formed with the lower frame 1, for example, by using two different plastic materials and employing a two-color injection molding process. Alternatively, the reflective layer 11 can be made of polyvinyl chloride (PVC) and coated onto the outer surface of the lower frame 1. The reflective layer 11 can also be separate from the lower frame 1. All these arrangements of the reflective layer 11 allow the light from the light guide 4 to be effectively reflected through the reflective layer 11, achieving the desired reflective light effect.

[0041] The reflective layer 11 is arranged on the outer surface of the lower frame 1 as large an area as possible. For example, the reflective layer 11 is arranged on the entire outer surface of the lower frame 1 along the length direction, so that the light from the light guide 4 can form multi-angle diffuse reflection over a large area, which is beneficial to achieving multi-layer light sensing effects.

[0042] like Figure 5 , Figure 6 As shown, in one specific embodiment, the covering 2 is provided with a second positioning member 52, and the bracket 3 is provided with a first mating part 53. Specifically, the main body 31 and / or the support 32 are provided with the first mating part 53, and the second positioning member 52 is correspondingly connected to the first mating part 53.

[0043] The covering 2 can be made of polyvinyl chloride (PVC) or polyurethane (PU), which has good elasticity, wear resistance, and weather resistance. By connecting the second positioning part 52 with the first mating part 53, the covering 2 can be stably positioned on the bracket 3.

[0044] The connection between the second positioning member 52 and the first mating part 53 can be achieved by snap-fitting, screwing, clamping, etc. Specifically, the first mating part 53 is located on the top of the main body 31 and the top of the support part 32 respectively. When the covering part 2 covers the main body 31 and the support part 32, the second positioning member 52 and the first mating part 53 are snap-fitted to achieve fixation. The connection between the covering part 2 and the bracket 3 is relatively quick, improving assembly efficiency.

[0045] like Figure 2 , Figure 7 As shown, in one specific embodiment, the bracket 3 is provided with a third positioning member 54. Specifically, the main body 31 is provided with a third positioning member 54 on the side wall away from the support part 32 and / or on the bottom of the main body 31, and the lower frame 1 is provided with a second mating part 55. The third positioning member 54 is correspondingly connected to the second mating part 55.

[0046] For example, the lower frame 1 includes a first frame 12 and a second frame 13. The first frame 12 is located at the bottom of the main body 31, and the second frame 13 is connected to the side wall of the first frame 12 and is disposed opposite to the covering 2 along the height direction of the lighting structure. The connection method between the first frame 12 and the second frame 13 can be snap-fit, screw-fit, clamping, etc., specifically the first frame 12 and the second frame 13 are snap-fitted.

[0047] The connection between the third positioning member 54 and the second mating part 55 can be achieved by snap-fitting, screwing, clamping, etc. Specifically, the third positioning member 54 is located on the side wall of the main body 31 away from the support part 32 and the bottom of the main body 31, respectively. The second mating part 55 is set on the first frame 12. When the main body 31 is installed on the lower frame 1, the third positioning member 54 and the second mating part 55 are snap-fitted to achieve fixation. The connection between the bracket 3 and the lower frame 1 is relatively quick, thereby effectively improving the assembly efficiency.

[0050] Example 3 This embodiment provides a vehicle, including the interior trim components described in the above embodiment.

[0051] The benefits of having interior trim components in a vehicle are the same as those described above.
