[0002] With the rapid development of automotive lighting technology and the increasing demands of users for the appearance of automotive lights, automotive lights have gradually evolved from early rounded and bulky shapes to slender shapes with a stronger crystal-like feel. As a result, there are more and more automotive lights that use thick-walled crystal-like components with LED light sources.
[0003] Because it is necessary to provide support for the thick-walled component, an upper trim ring is set above the thick-walled component and a lower trim ring is set below it; the lamp housing is arranged around the upper trim ring, the thick-walled component, and the lower trim ring. Due to the presence of the upper and lower trim rings, the entire lamp housing is larger in the vertical direction, resulting in a larger vertical dimension of the vehicle lighting device.
[0004] Therefore, it is necessary to provide a new vehicle lighting device and vehicle to solve the above-mentioned technical problems. Utility Model Content
[0005] The main objective of this invention is to provide a vehicle lighting device and vehicle, aiming to improve the technical problem of the large vertical dimensions of existing vehicle lighting devices.
[0006] To achieve the above objectives, this utility model proposes a vehicle lighting device, comprising:
[0007] The housing includes a lampshade, a lamp housing, a lower decorative ring, and an upper decorative ring. The lamp housing is mounted on the lampshade and has an inner cavity. The lower decorative ring and the upper decorative ring are both disposed on the side of the lamp housing facing the lampshade.
[0008] Light source, wherein the number of light sources is two;
[0009] A light guide assembly, wherein the lower decorative ring has a first mounting position, the light guide assembly is mounted at the first mounting position, and the two light sources are respectively mounted at both ends of the light guide assembly;
[0010] A thick-walled component has a first protrusion formed on it, and a lower decorative ring has a second mounting position. The first protrusion is engaged with the second mounting position. The thick-walled component is located between the light guide assembly and the lampshade. The light guide assembly is used to reflect the light emitted by the light source and allow it to pass through the thick-walled component and the lampshade in sequence.
[0011] In one embodiment, the lower trim ring has a first fixing hole, the lamp housing has a second fixing hole, and the vehicle lighting device includes a first locking member that passes through the first fixing hole and is installed in the second fixing hole.
[0012] In one embodiment, a second protrusion is formed on the thick-walled member in a vertical direction, and the upper and lower decorative rings abut against the two sides of the second protrusion, respectively.
[0013] In one embodiment, the upper trim ring has a third fixing hole, the lamp housing has a fourth fixing hole, and the vehicle lighting device includes a second locking member that passes through the third fixing hole and is installed in the fourth fixing hole.
[0014] In one embodiment, the light guide assembly includes a light guide element and light guide teeth disposed on the side of the light guide element away from the thick-walled member, wherein the lengths of the light guide teeth, the light guide element, and the lampshade are all equal.
[0015] In one embodiment, the length of the thick-walled member is greater than or equal to the length of the light guide.
[0016] In one embodiment, a first pattern is formed on the side of the thick-walled member facing the light guide.
[0017] In one embodiment, the thick-walled member has a second pattern formed on the side facing the lampshade.
[0018] In one embodiment, the second bump has a textured surface on the side facing the light guide.
[0019] This utility model also provides a vehicle, including a cover plate, a bumper, and the vehicle lighting device described above, wherein a mounting groove is formed between the cover plate and the bumper, and the lamp cover is mounted in the mounting groove.
[0020] In the above solution, the vehicle lighting device includes a housing, a light source, a light guide assembly, and a thick-walled component. The housing includes a lamp cover, a lamp housing, a lower trim ring, and an upper trim ring. The lamp housing is mounted on the lamp cover and has an inner cavity. The lower trim ring and the upper trim ring are both located on the side of the lamp housing facing the lamp cover. There are two light sources. The lower trim ring has a first mounting position, and the light guide assembly is mounted on the first mounting position. The two light sources are respectively mounted on both ends of the light guide assembly. A first protrusion is formed on the thick-walled component, and the lower trim ring has a second mounting position. The first protrusion is engaged with the second mounting position. The thick-walled component is located between the light guide assembly and the lamp cover. The light guide assembly is used to reflect the light emitted by the light source and pass through the thick-walled component and the lamp cover in sequence. Specifically, two light sources are installed at both ends of the light guide assembly. When the power is turned on, these two light sources emit light. A portion of the light emitted from each light source is then emitted from both ends of the light guide assembly. The light guide assembly reflects this light to the thick-walled component and then through it and the lampshade. Finally, the light covering the entire lampshade shines through to the external environment, completing the lighting function. The lampshade is usually made of transparent or semi-transparent material. Its function is not only to protect the internal components but also to adjust the light transmission effect, such as making the light softer or altering its intensity. The color of the light, etc.; In this vehicle lighting device, the thick-walled component is also supported by the lower and upper trim rings, with the lower trim ring located below the thick-walled component and the upper trim ring located above it. However, since both the lower and upper trim rings are mounted on the lamp housing, it is equivalent to extending the lower and upper trim rings towards the lamp housing on the side opposite to the lamp cover. In this way, the upper and lower trim rings are arranged front and back with the lamp cover, which can reduce the vertical length of the lamp cover, thereby reducing the vertical length of the vehicle lighting device, and making the entire vehicle lighting device more slender.

[0031] Please see Figures 1 to 3This utility model proposes a vehicle lighting device 100, including a housing 1, a light source 2, a light guide assembly, and a thick-walled member 4. The housing 1 includes a lampshade 11, a lamp housing 12, a lower decorative ring 5, and an upper decorative ring 7. The lamp housing 12 is mounted on the lampshade 11 and has an inner cavity. The lower decorative ring 5 and the upper decorative ring 7 are both located on the side of the lamp housing 12 facing the lampshade 11. There are two light sources 2. The lower decorative ring 5 has a first mounting position 51, and the light guide assembly is mounted on the first mounting position 51. The two light sources 2 are respectively mounted on both ends of the light guide assembly. A first protrusion 41 is formed on the thick-walled member 4, and a second mounting position 52 is formed on the lower decorative ring 5. The first protrusion 41 is engaged with the second mounting position 52. The thick-walled member 4 is located between the light guide assembly and the lamp housing 11. The light guide assembly is used to reflect the light emitted by the light source 2 and pass through the thick-walled member 4 and the lamp housing 11 in sequence. Specifically, two light sources 2 are installed at both ends of the light guide assembly. When the power is turned on, the two light sources 2 emit light. Then, some of the light emitted by the two light sources 2 is emitted from both ends of the light guide assembly to the light guide assembly. The light guide assembly reflects this light to the thick-walled component 4 and then passes through the thick-walled component 4 and the lampshade 11 in sequence. Finally, the light covering the entire lampshade 11 shines through the lampshade 11 into the external environment, completing the lighting function. The lampshade 11 is usually made of transparent or semi-transparent material. Its function is not only to protect the internal components but also to adjust the light transmission effect, such as making the light softer or changing the color of the light. In this embodiment, the thick-walled member 4 is also supported by the lower decorative ring 5 and the upper decorative ring 7. The lower decorative ring 5 is also located below the thick-walled member 4, and the upper decorative ring 7 is also located above the thick-walled member 4. However, since the lower decorative ring 5 and the upper decorative ring 7 are both installed on the lamp housing 12, it is equivalent to extending the lower decorative ring 5 and the upper decorative ring 7 toward the lamp cover 11 on the side of the lamp housing 12 opposite to the lamp cover 11. In this way, the upper decorative ring 7 and the lower decorative ring 5 are arranged in front and behind the lamp cover 11, which can reduce the vertical length of the lamp cover 11, thereby reducing the vertical length of the vehicle lighting device 100, and making the entire vehicle lighting device 100 more slender.
[0032] Please see Figures 1 to 3 In one embodiment, the lower trim ring 5 has a first fixing hole 53, the lamp housing 12 has a second fixing hole 121, and the vehicle lighting device 100 includes a first locking member 6, which passes through the first fixing hole 53 and is installed in the second fixing hole 121. This arrangement allows for quick removal and installation of the lower trim ring 5, and this fixing method ensures that the lower trim ring 5 is more securely installed inside the lamp housing 12.
[0033] Please see Figures 1 to 3In one embodiment, a second protrusion 42 is formed on the thick-walled member 4, which is arranged vertically. The upper decorative ring 7 and the lower decorative ring 5 abut against the two sides of the second protrusion 42, respectively. The thick-walled member 4 also has a second protrusion 42 arranged vertically. In this way, the upper decorative ring 7 and the lower decorative ring 5 abut against the two sides of the second protrusion 42, clamping the second protrusion 42. Furthermore, the first protrusion 41 is engaged in the second mounting position 52 of the lower decorative ring 5. This further improves the installation firmness of the thick-walled member 4 and further ensures that the thick-walled member 4 will not fall off.
[0034] Please see Figures 1 to 3 In one embodiment, the upper trim ring 7 has a third fixing hole 71, the lamp housing 12 has a fourth fixing hole 122, and the vehicle lighting device 100 includes a second locking member 8, which passes through the third fixing hole 71 and is installed in the fourth fixing hole 122. This arrangement allows for quick removal and installation of the upper trim ring 7, and this fixing method ensures that the upper trim ring 7 is more securely installed inside the lamp housing 12.
[0035] Please see Figures 1 to 3In one embodiment, the light guide assembly includes a light guide 3 and a light guide tooth 31 disposed on the side of the light guide 3 away from the thick-walled member 4. The lengths of the light guide tooth 31, the light guide 3, and the lamp cover 11 are all equal. Two light sources 2 are installed at both ends of the light guide 3. When the power is turned on, the two light sources 2 emit light. Then, a portion of the light emitted by the two light sources 2 enters the light guide 3 from both ends. The light guide 3 is a component that can conduct light and is usually made of transparent or translucent materials, such as plastic or glass. The light entering the light guide 3 travels back and forth, and a portion of the light emitted by the two light sources 2 is emitted onto the light guide teeth 31. The light guide teeth 31 reflect this light and penetrate the lampshade 11. The function of these light guide teeth 31 is to reflect the light emitted from the light sources 2 to the light guide teeth 31. Since the length of the light guide teeth 31 is equal to the length of the lampshade 11, the reflected light will cover the entire lampshade 11. The angle and direction of reflection depend on the design of the light guide teeth 31, with the aim of allowing as much light as possible to penetrate the lampshade 11 and in the desired direction. The light rays are emitted in a wide and wide range. After being reflected by the light guide teeth 31, the light rays eventually pass through the lamp cover 11. Finally, the light rays covering the entire lamp cover 11 illuminate the external environment, completing the lighting function. The lamp cover 11 is usually made of transparent or semi-transparent material. Its function is not only to protect the internal components, but also to adjust the light transmission effect, such as making the light softer or changing the color of the light. Unlike the traditional vehicle lighting device 100 with multiple light sources 2, this embodiment uses the light guide 3 and the light guide teeth 31 to reflect the light so that the light covers the entire lamp cover 11. This eliminates the need for more light sources 2, reducing the cost of using the light sources 2 and thus reducing the cost of the entire vehicle lighting device 100. Furthermore, the light guide 3 and the thick-walled component 4 work together to emit light, making the vehicle lighting device 100 emit light more evenly and with a greater sense of transparency.
[0036] Similarly, in a conventional vehicle lighting device 100 with multiple light sources 2, the simultaneous emission of light from multiple light sources 2 may result in a grainy visual effect, which could affect the use of the vehicle. However, in the above embodiment, the light guide 3 and the light guide teeth 31 work together to reflect the light, so that the light emitted by the vehicle lighting device 100 does not have a grainy appearance.
[0037] Furthermore, the aforementioned light source 2 is an LED lamp. The advantages of LED lamps are: energy saving, fast response, long lifespan, and relatively low cost.
[0038] Furthermore, the light source 2 can be a white light, a yellow light, and a red light, or it can be a dual-color LED light with both white and yellow light. The reason why a dual-color LED light emits two colors is that it uses two chips, both packaged in the same bracket. Generally, it is a three-pin dual-color light. Three-pin dual-color lights can be either common cathode or common anode. For a common cathode dual-color light, one pin is the cathode, and the other two pins are the anodes of the two colors, respectively.
[0039] Furthermore, the lampshade 11 and the lamp housing 12 are bonded together with sealant to form a sealed, waterproof outer shell 1. The lampshade 11 can be colorless and transparent, or it can be red semi-transparent, smoky gray semi-transparent, yellow semi-transparent, etc., while the lamp housing 12 is an opaque lamp housing 12.
[0040] Furthermore, the vehicle lighting device 100 may be a vehicle daytime running light, front position light, front turn signal, rear position light, brake light, and rear turn signal, etc.
[0041] Please see Figures 1 to 3 In one embodiment, the length of the thick-walled member 4 is greater than or equal to the length of the light guide member 3. Two light sources 2 are installed at both ends of the light guide member 3. When the power is turned on, the two light sources 2 will emit light. Then, part of the light emitted by the two light sources 2 will enter the light guide member 3 from both ends of the light guide member 3. The light entering the light guide member 3 will go back and forth. Part of the light emitted by the two light sources 2 will be emitted onto the light guide teeth 31. The light guide teeth 31 will reflect these light rays to the thick-walled member 4. Then, the light passes through the thick-walled member 4 and continues to be emitted towards the lamp cover 11, covering the entire lamp cover 11. Then, the light covering the entire lamp cover 11 will shine through the lamp cover 11 and illuminate the external environment, completing the lighting function. By setting the crystal-like thick-walled member 4, the appearance of the vehicle lighting device 100 is made more beautiful. Since the length of the thick-walled member 4 is greater than or equal to the length of the light guide member 3, the entire thick-walled member 4 will emit light, making the overall appearance more beautiful.
[0042] In one embodiment, a first pattern is formed on the side of the thick-walled member 4 facing the light guide member 3. Specifically, two light sources 2 are installed at both ends of the light guide member 3. When the power is turned on, the two light sources 2 emit light. Then, part of the light emitted by the two light sources 2 enters the light guide member 3 from both ends of the light guide member 3. The light entering the light guide member 3 will go back and forth. Part of the light emitted by the two light sources 2 will be emitted onto the light guide teeth 31. The light guide teeth 31 will reflect these light rays onto the thick-walled member 4. When the light is reflected onto the first pattern of the thick-walled member 4, the first pattern will further refract the light, making the light more concentrated. In this way, the light after refraction passes through the thick-walled member 4 and continues to be emitted towards the lamp cover 11, covering the entire lamp cover 11. Then, the light covering the entire lamp cover 11 will shine through the lamp cover 11 and illuminate the external environment. In this way, the light illuminating the external environment will be brighter, so that the brightness emitted by the vehicle lighting device 100 can meet the requirements of traffic rules.
[0043] In one embodiment, a second pattern is formed on the side of the thick-walled member 4 facing the lampshade 11. Two light sources 2 are installed at both ends of the light guide 3. When the power is turned on, the two light sources 2 will emit light. Then, part of the light emitted by the two light sources 2 enters the light guide 3 from both ends of the light guide 3. The light entering the light guide 3 will go back and forth. Part of the light emitted by the two light sources 2 will be emitted onto the light guide teeth 31. The light guide teeth 31 will reflect these light rays onto the thick wall part 4. When the light is reflected onto the first pattern of the thick wall part 4, the first pattern will further refract the light into the thick wall part 4, making the light more concentrated. The light after being refracted again passes through the thick wall part 4 and is then projected onto the second pattern on the side of the thick wall part 4 facing the lamp cover 11. The second pattern will diffuse the light, and finally the light emitted by the light source 2 will be evenly emitted out of the lamp cover 11 for illumination. In this way, the brightness emitted by the vehicle lighting device 100 can be more uniform along the length of the lamp cover 11, and there will be no situation where the brightness of a certain position of the vehicle lighting device 100 is lower or higher than that of other positions.
[0044] In one embodiment, the second protrusion 42 has a textured surface on the side facing the light guide 3. To prevent the light reflected from the light guide teeth 31 from shining directly forward through the gap between the second protrusion 42 and the upper decorative ring 7, forming a bright spot, the second protrusion 42 has a textured surface on the side facing the light guide. The tiny uneven structure on the textured surface can scatter the light, making the light distribution more uniform, reducing light spots and glare, lowering the light intensity, and improving the comfort of lighting.
[0045] This utility model also provides a vehicle, including a cover plate 101, a bumper 102, and the aforementioned vehicle lighting device 100. A mounting groove 103 is formed between the cover plate 101 and the bumper 102, and a lampshade 11 is mounted in the mounting groove 103. Since the vehicle includes all embodiments of the aforementioned vehicle lighting device 100, it possesses at least all the beneficial effects brought about by all the aforementioned embodiments, which will not be described in detail here.
[0046] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
