[0002] Under the requirements of the market and consumers for personalized, fashionable, and trendy appearances, more and more automotive vehicle lamps on the market must not only meet regulatory requirements but also add lighting methods and appearances that are more in line with aesthetic and technological trends. To achieve this goal, currently on the market, a light pattern with a complex shape is usually presented by splicing multiple thick walls. However, this solution has a high cost, and the size and assembly requirements for the thick walls are relatively strict. More importantly, dark areas will appear at the joints of the thick walls, ultimately resulting in uneven lighting effects. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above problems existing in the prior art, and provide a vehicle lamp that realizes a complex appearance and a uniform lighting effect through a three-in-one light pattern. It includes a thick wall member 3, a reflector bowl 4, an inner optical lens 5, and a PCBA circuit board 6.

The thick wall member 3 includes an upper thick wall 3-1, a middle thick wall 3-2, and a lower thick wall 3-3. The reflecting direction of the reflector bowl is directly opposite to each thick wall on the thick wall member 3.

[0004] Further, the thick wall member 3 is integrally formed and is divided into an upper thick wall 3-1, a middle thick wall 3-2, and a lower thick wall 3-3 by two groups of grooves. This design can form multiple independent light-emitting surfaces on the same thick wall member, thereby realizing a complex shape and appearance, and avoiding the dark areas and uneven lighting problems caused by splicing multiple thick wall members.

[0005] Furthermore, both the upper thick wall 3-1 and the lower thick wall 3-3 are slender strips with one end straight and the other end bent towards each other. The middle thick wall 3-2 is quadrilateral and is located between the upper and lower thick walls, thereby forming an asymmetric appearance shape similar to a C shape.

[0006] Further, reflection patterns 9 are provided on the light-emitting surfaces of the upper thick wall 3-1, the middle thick wall 3-2, and the lower thick wall 3-3. The reflection patterns 9 corresponding to different thick walls are the same or different.

Detailed Description of the Embodiment

[0019] Such as Figures 1-6A kind of headlight with a three-in-one light type to achieve a complex appearance and a uniform lighting effect, mainly including an outer lens 1, a main trim ring 2, a thick-wall part 3, a reflector bowl 4, an inner optical lens 5, a PCBA circuit board 6, and a lamp housing 7. Among them, the PCBA circuit board 6 is fixed on the reflector bowl 4 by screws, and the LED light source on the PCBA circuit board 6 is directly opposite to the reflecting surface of the reflector bowl 4. The reflector bowl 4 is fixedly connected to the inner optical lens 5 by screws or snaps, and the inner optical lens 5 is fixedly connected to the thick-wall part 3 by screws, thus forming a thick-wall component as shown in Figures 3-4 The thick-wall component is fixedly connected to the main trim ring 2 and the housing 7 by screws respectively. The outer lens 1 and the lamp housing 7 are fixedly connected by sealant and other components are encapsulated between the two, thus realizing the sealed assembly of the whole lamp.

[0020] As shown in Figure 3 or 4, the thick-wall part 3 is an integrally formed plastic part, including an upper thick wall 3-1, a middle thick wall 3-2, and a lower thick wall 3-3. The three together form an asymmetric complex light-emitting shape similar to a C shape. The middle thick wall 3-2 is quadrilateral and is separated from the upper thick wall 3-1 and the lower thick wall 3-3 by grooves. The upper thick wall 3-1 and the lower thick wall 3-3 are similar in shape, both being slender strips with one end straight and the other end bent towards each other. Reflection patterns 9 in the shape of corn kernels and the like are provided on the outer surfaces of the upper thick wall 3-1, the middle thick wall 3-2, and the lower thick wall 3-3.

[0021] As shown in Figure 4 The reflector bowl 4 and the inner optical lens 5 are also similar in shape to the thick-wall part 3. Three reflecting surfaces matching the upper thick wall 3-1, the middle thick wall 3-2, and the lower thick wall 3-3 are provided on the reflector bowl 4 for directing the light emitted by each LED light source to the corresponding thick wall, and then emitting it from its light-emitting surface to achieve a specific shape and lighting effect.

[0022] An inner optical lens 5 is provided between the reflector bowl 4 and the thick-wall part 3. The inner optical lens 5 includes a horizontal plate 5-1 and a vertical baffle 5-2. The three thick walls of the thick-wall part 3 surround the vertical baffle 5-2 of the inner optical lens 5, and the main trim ring 2 is fixed in the installation groove in the middle of the vertical baffle 5-2 to play a decorative and shielding role. Skin patterns 8 are provided on both the front and back of the light-transmitting area of the horizontal plate 5-1. The light reflected by the reflector bowl 4 passes through the skin patterns 8 on the inner optical lens 5 and then continues to pass through the thick-wall part 3 and the outer lens 1 and is emitted.

[0023] The number of PCBA circuit boards 6 is 4, and they are arranged according to the shape of the thick-wall part 3. A number of LED light sources are soldered on each PCBA circuit board, respectively responsible for providing light sources for the upper thick wall 3-1, the middle thick wall 3-2, and the lower thick wall 3-3.

[0024] The optical path diagram of this headlight is as shown in Figures 5-6As shown, the LED on the PCBA circuit board 6 emits light, and the light is reflected by the reflecting bowl 4 to the light-transmitting area of the inner spectacle lens 5. After being scattered by the skin patterns on its front and back sides, it passes through each thick wall of the thick wall part 3, and finally passes through the outer lens 1 and shoots forward, thus achieving a uniform lighting effect and a unique appearance.

[0025] Compared with the traditional lighting scheme of multiple thick walls spliced together, the present utility model adopts a thick wall part with a unique shape and uses grooves to physically divide it into multiple thick wall lighting areas, avoiding the dark area problem of multiple thick wall splicing. It is not only simple and efficient in assembly but also can achieve a better lighting effect. In addition, the internal structure of the whole lamp is more stable, and there is also an installation space reserved for adding other vehicle lamp functions, which not only meets the optical functions and regulatory requirements but also ensures the requirements of customers for the appearance, light pattern and light emission uniformity of the vehicle lamp.
