Description
Technical Field
[0001] This utility model relates to a vehicle light component, and more specifically, to a one-piece thick-walled signal light assembly. Background Technology
[0002] Vehicle lights are crucial safety warning components, with taillights primarily serving to transmit signals such as vehicle outline and braking warning. Different light colors correspond to different driving signals: red light for braking warning, and yellow light for outline and driving warning, directly ensuring vehicle safety and traffic order. With the iteration of vehicle light technology, the light-emitting structure of vehicle lights has gradually upgraded from the traditional direct-light structure of LED chips to a thick-walled light guide structure. Compared to the direct-light solution, the thick-walled light guide structure offers more uniform light distribution and better continuity of the light-emitting surface, effectively eliminating localized glare and dark areas. It also offers greater design flexibility, adapting to the diverse design needs of automakers, and features lower power consumption, longer lifespan, and excellent waterproof and dustproof performance, significantly improving the quality and visual warning effect of vehicle lights, making it the current mainstream development direction for vehicle lights.
[0003] However, conventional thick-walled light guide headlights still have significant technical shortcomings. For example, taillights often need to illuminate both the brake lights (red) and turn signals (yellow), and existing single thick-walled light guides cannot achieve simultaneous illumination of both colors, requiring multiple independent thick-walled light guides. To achieve multi-signal illumination, multiple thick-walled components with different functions need to be assembled and fixed inside the headlight. During vehicle operation, continuous vibrations can easily cause the assembly and fixing points of the thick-walled components to loosen, leading to friction and powder generation. This also causes the assembly gaps to widen and the play to increase, resulting not only in abnormal headlight noise and light beam misalignment but also reducing the overall structural stability and lifespan of the headlight. Utility Model Content

[0013] In summary, this utility model has the following beneficial effects: This solution integrates the light-emitting functions of three different light colors through an integrally formed thick-walled structure.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] Example: See Figure 1 and Figure 2The integrated thick-walled signal light assembly includes an integrated thick-walled component 1, a first light source 10, a second light source 20, and a third light source 30, each with a different color. The integrated thick-walled component 1 includes a first thick wall 40, a second thick wall 50 intersecting with the first thick wall 40, and a third thick wall 60 connected end-to-end with the second thick wall 50. The third thick wall 60 and the second thick wall 50 are distributed at an angle of 90°, and a reflective surface 70 is provided at the transition section. One end of the first thick wall 40 has a first light-incident side 41, and the other end of the first thick wall 40 has a first light-outcrystal side 42. The second thick wall 50 has a far-reaching light-outcrystal side. A second light-incident side 51 is provided at one end away from the reflective surface 70, and a second light-exiting side 61 is provided at one end of the third thick wall 60 away from the reflective surface 70; any one or two of the first light source 10, the second light source 20 and the third light source 30 face the first light-incident side 41, and the remaining light sources face the second light-incident side 51; the incident light entering from the first light-incident side 41 passes through the first thick wall 40 and exits from the first light-exiting side 42, which is the first light path; the incident light entering from the second light-incident side 51 passes through the second thick wall 50, the reflective surface 70 and the third thick wall 60 and exits from the second light-exiting side 61, which is the second light path.
[0018] For details, see Figure 2 The angle between the second thick wall 50 and the reflective surface 70 is a, and the angle between the third thick wall 60 and the reflective surface 70 is b, both a and b are 135°.
[0019] For details, see Figure 2 The first thick wall 40 and the second thick wall 50 intersect perpendicularly, the first thick wall 40 and the third thick wall 60 are parallel, and the first light-emitting side 42 and the second light-emitting side 61 are on the same side.
[0020] For details, see Figure 4 The reflective surface 70 has several arrayed columnar reflective surfaces 71, each with a concave circular arc cylindrical structure. The columnar reflective surfaces 71 can disperse the incident light rays in directions perpendicular to the length of the columnar reflective surfaces 71, thus achieving a uniform light effect.
[0021] For details, see Figure 4 Both the first light-incident side 41 and the second light-incident side 51 are provided with a plurality of spherical light-concentrating parts 81 distributed along their respective length directions. A cylindrical light-concentrating part 82 is also provided on the first light-incident side 41, located between any two adjacent spherical light-concentrating parts 81. The cylindrical outline of the cylindrical light-concentrating part 82 is arc-shaped, and the length direction of the cylindrical surface is parallel to the length direction of the first light-incident side 41. Both the spherical light-concentrating parts 81 and the cylindrical light-concentrating parts 82 have a light-concentrating effect. The difference is that the spherical light-concentrating part 81 can focus the diffused light into a small circular area, which appears as a circular light spot, while the cylindrical light-concentrating part 82 can focus the diffused light into a long, thin strip area, which appears as a long, thin light spot.
[0022] For details, see Figure 1 The first light-emitting side 42 is provided with a first texture 421, and the second light-emitting side 61 is provided with a second texture 611.
[0023] For details, see Figure 1 The first texture 421 and the second texture 611 are both composed of arrayed protrusions, making the shape of the first texture 421 and the second texture 611 resemble a flat corn kernel structure.
[0024] For details, see Figure 2 and Figure 3 The first light source 10 is directly opposite the spherical focusing part 81 on the first light-incident side 41, the second light source 20 is directly opposite the cylindrical focusing part 82, and the third light source 30 is directly opposite the spherical focusing part 81 on the second light-incident side 51; the first light source 10 is red light, the second light source 20 is white light, and the third light source 30 is yellow light.
[0025] For details, see Figure 1 The first light source 10 and the second light source 20 are disposed on the first PCB board 91, and the third light source 30 is disposed on the second PCB board 92.
[0026] In actual production, the integrated thick-walled component 1 is integrally injection molded from PC material with excellent light transmittance. The three thick-walled structures are connected as a whole, fundamentally avoiding the problems of loose assembly and friction noise of multiple thick-walled components. At the same time, this embodiment is equipped with three colors of light sources, of which the first light source 10 is red light, the second light source 20 is white light, and the third light source 30 is yellow light.
[0027] When the first light source 10 is activated, red light enters the first thick wall 40 from the spherical focusing part 81 of the first light-incident side 41. After being conducted through the first thick wall 40, it is emitted from the first light-exiting side 42. The first texture 421 homogenizes the emitted light, forming a uniform and continuous red light-emitting surface. When the second light source 20 is activated, white light enters the first thick wall 40 from the cylindrical focusing part 82 of the first light-incident side 41. Similarly, after being homogenized by the first light-exiting side 42, it is emitted, forming a white light-emitting surface. Compared to the central focusing effect of the spherical focusing part 81, the cylindrical focusing part 82 is linearly focused, so the white light distribution is relatively uniform. When the third light source 30 is activated, the yellow light is focused by the spherical focusing part 81 of the second incident light side 51 and enters the second thick wall 50. It is then conducted through the second thick wall 50 to the reflective surface 70. Since the angles between the second thick wall 50, the third thick wall 60, and the reflective surface 70 are equal, the incident yellow light is completely reflected by the reflective surface 70 and enters the third thick wall 60 completely. Finally, it is homogenized by the second texture 611 of the second emitting light side 61 and emitted, forming a yellow warning light-emitting surface. All three light sources can operate independently, and the first light source 10 and the second light source 20 can be turned on simultaneously. The first light path of the first light source 10 and the second light source 20, and the second light path of the third light source 30, do not interfere with each other and can emit light independently. Applying this embodiment to automotive taillights, when braking, both red and white light illuminate simultaneously, providing the strongest warning effect; when driving at night, the red light illuminates to alert following vehicles; and when turning or indicating a direction is required, the yellow light illuminates.
[0028] This solution integrates the light-emitting functions of three different light colors through a one-piece molded thick-walled structure. It can realize three light signal prompts with only one thick-walled component, reducing the number of internal parts and assembly processes of the headlight, reducing the risk of structural loosening caused by the assembly of multiple parts, and setting the two light-emitting sides on the same side, which meets the requirements of the integrated design of the headlight appearance, and combines structural stability and design aesthetics.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
