[0039] Throughout the history of the automotive industry, vehicle lighting systems have always been a key element in design and safety. With technological advancements, vehicle lighting design continues to evolve to meet higher safety standards and driver needs. In the automotive lighting field, a vehicle's signal lights communicate the vehicle's driving intentions and status to other drivers, allowing them to promptly obtain traffic information ahead based on the vehicle's signal lights. Therefore, a vehicle's signal lighting system is a vital component in ensuring road safety.

[0040] According to the applicant's research, current headlights mainly use halogen lamps, LED lamps, etc. as light sources. As point light sources, this type of light source has the characteristic of concentrated brightness. The light it emits enters the human eye directly or indirectly through a lens, which can easily cause visual discomfort. Especially when following or meeting a car at night, the brightness of the car in front suddenly appears in high contrast with the surrounding environment, which can easily cause temporary vision loss in drivers of surrounding vehicles and interfere with their vision.

[0041] In view of this, the present invention provides a vehicle lamp to solve the above technical problems.

[0042] See also Figure 1 and Figure 2In one embodiment of the present utility model, the vehicle lamp 100 includes a lamp housing 1, a bracket 2, a light source 3, a light guide 4 and a thick-walled member 5, wherein the bracket 2 is installed on the lamp housing 1; the light source 3 is installed on the bracket 2; the light guide 4 is installed on the bracket 2, the light source 3 is arranged at one end of the light guide 4, and the light guide 4 can receive the light emitted by the light source 3; the thick-walled member 5 includes at least two thick-walled lenses 51, the thick-walled lens 51 includes a light guiding portion 511 and a light scattering portion 512 connected to each other, the light guiding portion 511 can transmit light to the light scattering portion 512, the light guiding portions 511 of two adjacent thick-walled lenses 51 are connected to each other, the two adjacent light scattering portions 512 are arranged at intervals, and the light guiding portion 511 is arranged in close contact with the light guide 4.

[0043] Specifically, light source 3 comprises an LED lamp, which is mounted on one side of bracket 2. Lamp housing 1 is mounted in a reserved position in the vehicle frame, and bracket 2 is mounted on the inner side of lamp housing 1, i.e., the side of lamp housing 1 facing away from the vehicle frame. Light guide 4 is arranged in an elongated strip with a circular or rectangular cross-section. Light guide 4 extends along the length of bracket 2 and is made of one of polycarbonate (PC) and polymethyl methacrylate (PMMA). Light source 3 is connected to the ends of light guide 4. In this embodiment, due to the short length of light guide 4, there is only one light source 3, which is mounted on one side of light guide 4. In other embodiments, if light guide 4 is longer, the brightness of light from light source 3 may decrease when it reaches the end of light guide 4 away from light source 3. Therefore, light sources 3 are connected to both ends of light guide 4. The function of light guide 4 is to initially guide and shape the light emitted by light source 3 so that the light can propagate in the designed direction and shape. The thick-walled member 5 is used to receive the light transmitted from the light guide 4 and diffuse it to the outside. The bottom surface of its light guide portion 511 is arranged in contact with the light guide 4 to prevent the light emitted from the light guide 4 from scattering in the air and reducing the utilization rate of the light. In this embodiment, the thick-walled member 5 includes three thick-walled lenses 51, which are arranged in an integrated manner. During manufacturing, only one mold needs to be designed to mass-produce the thick-walled member 5, reducing design and manufacturing costs. During installation, the thick-walled member 5 only needs to be installed as a whole on the bracket 2 to complete the installation of the three thick-walled lenses 51. The light guide 4 and the light source 3 are both installed on the bracket 2, making the installation process simpler and helping to reduce labor costs. By arranging the light-scattering portions 512 at intervals, when the light source 3 is turned on, three bright areas are formed in the headlight 100, making the headlight 100 more recognizable when turned on, thereby further improving the lighting effect of the headlight 100 and more clearly conveying the driving intention to surrounding vehicles.

[0044] In the technical solution provided in this embodiment, the vehicle lamp 100 includes a lamp housing 1, a bracket 2, a light source 3, a light guide 4 and a thick-walled part 5, wherein the bracket 2 is installed on the lamp housing 1; the light source 3 is installed on the bracket 2; the light guide 4 is installed on the bracket 2, and the light source 3 is arranged at one end of the light guide 4, and the light guide 4 can receive the light emitted by the light source 3; the thick-walled part 5 includes at least two thick-walled lenses 51, and the thick-walled lens 51 includes a light guiding part 511 and a light scattering part 512 that are connected to each other, and the light guiding part 511 can transmit light to the light scattering part 512, and the light guiding parts 511 of two adjacent thick-walled lenses 51 are connected to each other, and the two adjacent light scattering parts 512 are arranged at intervals, and the light guiding part 511 is arranged in close contact with the light guide 4. Through this arrangement, under the action of the light guide 4, the light emitted by the light source 3 into the light guide 4 is diffused along the light guide 4, so that the distribution of the light emitted by the light guide 4 into the light guide portion 511 is more uniform, and the scattered light portion 512 can further diffuse the light to achieve a more uniform lighting effect, avoiding the generation of bright spots in the car lamp 100, thereby avoiding glare to the drivers of surrounding vehicles, and further avoiding interference with the vision of the drivers of surrounding vehicles.

[0045] Furthermore, in one embodiment of the present invention, the vehicle lamp 100 further includes a decorative ring 6, which is mounted on the lamp housing 1 and encloses the lamp housing 1 to form a mounting cavity. The bracket 2, light source 3, light guide 4 and light guide portion 511 are disposed in the mounting cavity. A mounting hole 61 is formed in the decorative ring 6, and the light diffusing portion 512 passes through the mounting hole 61 on the side away from the lamp housing 1. The number of mounting holes 61 and the number of light diffusing portions 512 are the same, and adjacent mounting holes 61 are spaced apart, and the mounting holes 61 and the light diffusing portions 512 are disposed one-to-one. Figure 1 and Figure 3 The decorative ring 6 is mounted on the inner side of the lamp housing 1. Mounting holes 61 are defined in the decorative ring 6, corresponding to the positions of the light-scattering portions 512. In this embodiment, there are three mounting holes 61, each corresponding to a light-scattering portion 512. The end of the light-scattering portion 512 away from the lamp housing 1 passes through the mounting holes 61 and extends away from the lamp housing 1. The mounting holes 61 of the decorative ring 6 are used to allow the light-scattering portions 512 to pass through. The portion of the decorative ring 6 other than the mounting holes 61 is used to shield components or parts such as the bracket 2, light source 3, light guide 4, and light guide portion 511, thereby enhancing the overall aesthetics of the vehicle lamp 100.

[0046] In another embodiment, an inner cover is provided on the side of the decorative ring 6 away from the lamp housing 1. The inner cover is a transparent plastic member and is positioned over the mounting hole to serve as a protective layer for the light-scattering portion 512. The inner cover does not filter or absorb light, allowing light to pass directly through, thereby ensuring that the luminous effect of the light-scattering portion 512 is not affected. This arrangement allows the decorative ring 6 to be entirely positioned over the lamp housing 1, further improving the sealing of the mounting cavity.

[0047] In one embodiment of the present invention, the vehicle lamp 100 further includes a lampshade 7, which is mounted on the lamp housing 1. The lampshade 7 and the lamp housing 1 together form a storage space. The bracket 2, light source 3, light guide 4, thick-walled member 5, and decorative ring 6 are all disposed within the storage space. The decorative ring 6 divides the storage space into an installation cavity and an illumination cavity. The light-scattering portion 512 is disposed in the illumination cavity. The illumination cavity is enclosed by the lampshade 7 and the decorative ring 6 and is used to emit light to the outside of the vehicle lamp. The lampshade 7 is mounted on the lamp housing 1 and together with the lamp housing 1, forms a closed storage space. This structural design enhances the stability and durability of the vehicle lamp 100 and protects the internal components from external environmental influences, such as rain, dust, etc. At the same time, the integrated design makes the vehicle lamp 100 look neater and more beautiful. The design of the lampshade 7 can also be customized according to aesthetic requirements to match the overall design style of the vehicle.

[0048] In one embodiment of the present invention, please refer to Figure 4 , a positioning hole 21 is provided on the bracket 2, and the light source 3 is installed in the positioning hole 21. The size and shape of the positioning hole 21 are determined according to the overall size and shape of the light source 3. In this embodiment, the light source 3 includes a substrate and a luminous bead. After the light source 3 is installed in the positioning hole 21, one end of the light guide 4 is connected to the luminous bead so that the light emitted by the luminous bead can be transmitted into the light guide 4. The connection method of the light source 3 to the bracket 2 includes one of bonding, welding, snap connection and bolt connection. Through this arrangement, the installation process of the light source 3 is further simplified, so that the light source 3 can be quickly installed in the bracket 2, thereby saving work hours.

[0049] In one embodiment of the present invention, a mounting groove 22 is formed on the bracket 2. The extending direction of the mounting groove 22 is consistent with the length direction of the light guide 4. The light guide 4 is mounted in the mounting groove 22. Figure 4 The mounting groove 22 is provided on the side of the bracket 2 away from the lamp housing 1. The length and profile of the mounting groove 22 match the length and profile of the light guide 4. During manufacturing, the mounting groove 22 is integrally formed with the rest of the bracket 2, and no additional groove body is required. When installing the light guide 4, it is only necessary to place the light guide 4 on the bracket 2 and connect the light guide 4 to the bracket 2 to complete the installation. The connection method between the light guide 4 and the bracket 2 includes one of bonding, welding, snap connection and bolt connection. Through this arrangement, the installation process of the light guide 4 is reduced, and the installation position of the light guide 4 is more accurate, without the need for additional steps for adjustment, thereby saving labor hours without affecting the lighting effect of the vehicle lamp 100.

[0050] See also Figure 2In one embodiment of the present invention, an incident optical pattern portion 513 is provided on the side of the light guide portion 511 near the light guide member 4 to uniformly distribute the light entering the light guide portion 511 from the light guide member 4. The incident optical pattern portion 513 is used to receive the light transmitted to the light guide portion 511 by the light guide member 4. Providing the incident optical pattern portion 513 there can adjust the incident angle of the light entering the light guide portion 511 from the light guide member 4, making the light entering the light guide portion 511 more uniform and avoiding the generation of local bright spots in the light guide portion 511.

[0051] Furthermore, in one embodiment of the present invention, the surface of the light guide 4 is a curved convex surface, while the side of the light guide portion 511 closest to the light guide 4 is a curved concave surface. The curved convex surface and the curved concave surface are arranged in a close-fitting manner. This arrangement increases the contact area between the surface of the light guide 4 and the surface of the light guide portion 511, facilitating light transmission from the light guide 4 to the light guide portion 511, thereby improving the overall optical efficiency of the vehicle lamp 100 and reducing light energy loss. In one embodiment, the light guide portion 511 covers the surface of the light guide 4 to further enhance optical efficiency.

[0052] In one embodiment of the present invention, please refer to Figure 2 An exit optical pattern portion 514 is provided on the side of the diffuser portion 512 away from the lamp housing 1. This pattern portion 514 is used to evenly distribute the light emitted from the diffuser portion 512. The pattern portion 514 controls the direction and distribution of light as it exits the diffuser portion 512, thereby improving the lighting effect and safety of the vehicle lamp 100. Furthermore, when the light source 3 is not emitting light, the pattern portion 514 is positioned away from the lamp housing 1, facing the outside of the vehicle. Therefore, pedestrians or drivers can intuitively observe the pattern of the pattern portion 514. This arrangement achieves the visual effect of traditional optical patterns and enhances the aesthetics of the vehicle lamp 100. Furthermore, the design of the pattern portion 514 can enhance the personalization and formality of the vehicle lamp 100.
