Both the first and second thick walls have a bottom surface, an inner surface, and an outer surface. The bottom surface of the first thick wall is the light-incident surface, facing and close to the light source to receive light from it. Both sides of the first and second thick walls are patterned to reflect and scatter light at specific angles. The outer surface of the second thick wall is the light-emitting surface of the entire component, facing outwards from the vehicle.

This design results in better light uniformity, lower power consumption, and a balance between optical performance and energy efficiency.

Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle through lights, and specifically relates to a vehicle and a vehicle through light. Background Technology

[0002] As an important component of the exterior design of modern automobiles, especially new energy vehicles, the front continuous light not only provides basic lighting but also plays a crucial role in enhancing the overall visual appeal and strengthening brand recognition. Its smooth lines and technologically advanced shape seamlessly integrate with the front of the vehicle, effectively highlighting the futuristic and high-end feel of new energy vehicles.

[0003] Currently, the industry commonly uses LED light strips as the light source for automotive front continuous lights, employing an internal lens made of diffusing material for light distribution and mixing. While this solution can achieve a certain degree of uniformity in the light-emitting surface, several significant drawbacks exist in practical applications: First, the scattering effect of the diffusing material reduces the overall brightness of the lamp, and under specific viewing angles or lighting conditions, localized bright spots can appear, affecting the consistency of visual effects. Second, the diffusing material used in the internal lens itself absorbs and attenuates light, resulting in low light transmittance. To ensure the lamp meets regulatory and design requirements for brightness, it is often necessary to increase LED power, which directly increases overall lamp power consumption and causes more significant heat generation, adversely affecting the lamp's thermal management design, long-term reliability, and energy efficiency.

[0004] Therefore, existing optical solutions for through-light optics based on diffused material internal lenses cannot achieve an ideal balance between uniformity, brightness, power consumption, and thermal management. A new technical solution is urgently needed to balance optical performance and energy efficiency. Utility Model Content

[0018] This utility model provides a vehicle through light, the advantages of which are:

[0019] The core of this design lies in a specially designed thick-walled component.

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] The core of this utility model is to provide a vehicle and a vehicle through light that can balance optical performance and energy efficiency.

[0038] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] For details, please refer to Figures 1-5 The present invention provides a vehicle and a vehicle through light, including a thick-walled component 300.

[0040] The thick-walled component 300 is a Z-shaped double-layer thick-walled component, comprising a lower first thick-walled component 310 and an upper second thick-walled component 320. A portion of the upper surface of the first thick-walled component 310 is connected to a portion of the lower surface of the second thick-walled component 320, forming a Z-shaped structure. The bottom surface of the second thick-walled component 320 is adjacent to or connected to the other side of the first thick-walled component 310 via a transition surface.

[0041] Preferably, the Z-shaped structure of the thick-walled component 300 can be designed as a continuous arc transition, rather than a sharply angled line. That is, the connection between the first thick-walled layer 310 and the second thick-walled layer 320 is a smooth curved surface. This design also follows the aforementioned optical path principle, where light changes direction due to total internal reflection at the curved surface. The curved surface design helps reduce light energy loss and makes the thick-walled component more structurally strong and aesthetically pleasing with a streamlined appearance.

[0042] The bottom surface 330 of the first thick wall 310 is the light-incident surface, used to receive light from the light source. One side of the first thick wall 310 is configured to reflect the light from the light-incident surface to the other side of the first thick wall 310. The other side of the first thick wall 310 is configured to reflect the reflected light from the other side of the first thick wall 310 to the bottom surface of the second thick wall 320 and finally reach one side of the second thick wall 320. One side of the second thick wall 320 is configured to reflect the light from the other side of the first thick wall 310 to the other side of the second thick wall 320. The other side of the second thick wall 320 is the light-exit surface.

[0043] Both sides of the first thick wall layer 310 and both sides of the second thick wall layer 320 are provided with patterned surfaces. The patterns on each side of the first thick wall layer 310 and the second thick wall layer 320 can be designed with different densities, angles, and shapes as needed to precisely control the reflection angle and light emission effect. For example, to make the light band more uniform, the density of the pattern or the reflection angle can be set to be greater closer to the center of the light source, so as to distribute more light to a distance.

[0044] This solution provides a vehicle through-light, the core of which lies in a specially designed thick-walled component 300. The thick-walled component 300 is a Z-shaped, double-layered thick-walled structure, which can be considered as being formed by stacking and staggering a first thick-walled layer 310 and a second thick-walled layer 320. Both the first and second thick-walled layers 310 and 320 have a bottom surface 330, inner surfaces, and outer surfaces. The bottom surface 330 of the first thick-walled layer 310 is the light-incident surface, facing and close to the light source to receive light from it. Both sides of the first thick-walled layer 310 and both sides of the second thick-walled layer 320 are patterned surfaces, which reflect and scatter light at specific angles. The outer surface of the second thick-walled layer 320 is the final light-emitting surface of the entire thick-walled component 300, facing outwards from the vehicle and visible to the observer.

[0045] Through a unique Z-shaped double-layer thick-walled structure and side pattern design, the light emitted by point or line light sources enters the thick-walled component 300 through the light-incident surface, and then undergoes multiple reflections and light mixing through the reflection structure in the thick-walled component 300, transforming it into a uniform and bright linear light band.

[0046] The above settings result in better light uniformity, significantly reducing the power consumption of a single LED and thus lowering the overall power consumption of the lamp, achieving a balance between optical performance and energy efficiency.

[0047] In addition, due to the reduction in overall lamp power consumption and heat generation, the risk of fogging in the lamp is reduced, thus eliminating the need for an anti-fog coating and lowering the overall lamp manufacturing cost.

[0048] To further improve the uniformity of light emission from the thick-walled component 300, at least one end face of the second thick-walled component is provided with a supplementary light pattern surface 340. The grid-like supplementary light pattern 340 is designed on both sides of the thick-walled component at both ends, which solves the problem of dark areas at both ends when the long thick-walled component is lit.

[0049] Based on the above specific embodiments, the patterned surface and / or the supplementary light patterned surface 340 is a curved surface, and micro-patterned structures, such as sawtooth, spherical dot matrix, prism structure, etc., are provided on the curved surface.

[0050] This solution also includes a light source module and a circuit board 200. The circuit board 200 serves as the vehicle's electrical interface and structural support substrate, typically a printed circuit board (PCB) or a flexible printed circuit board (FPC), used for fixing and electrically connecting the light source module. The circuit board 200 connects to the vehicle's control system to receive control signals and supply power to the light source module.

[0051] The light source module is mounted on the circuit board 200 and may include multiple LEDs arranged in an array at a preset spacing and soldered onto the circuit board 200. The light source module serves as the light source for the entire through-light, and the light emitted from it is directly incident on the thick-walled component 300. The light source module includes, but is not limited to, LEDs; in other embodiments, it may also be other high-brightness point light sources such as laser diodes.

[0052] This solution also includes a housing 100 and a faceplate 500. The faceplate 500 covers the opening of the housing 100. The circuit board 200 and the thick-walled component 300 are arranged sequentially from bottom to top within the mounting cavity formed by the housing 100 and the faceplate 500. The housing 100, as the structural foundation of the entire through-light, is typically injection molded from plastic and is elongated in shape with an upward-facing opening to accommodate other components.

[0053] The housing 100 has mounting holes and clips on its bottom or side walls for securing the entire lamp body to the front or rear of the vehicle. The face shield 500 is typically made of transparent or translucent PC or PMMA light-transmitting material, and its edges are tightly secured to the housing 100 by ultrasonic welding, gluing, or clip-on connection to ensure the sealing of the mounting cavity and prevent moisture and dust from entering.

[0054] In a specific embodiment, the faceplate 500 innovatively uses a rectangular shape that is narrower at the top and wider at the bottom, while the market standard is mostly an inverted rectangular shape with a continuous light strip. Light from the thick-walled component 300 shines through the faceplate 500. This design not only gives the front or rear of the vehicle a unique geometric aesthetic and recognizability, but its multi-angled slopes also help guide airflow and can disperse external impacts to a certain extent, improving durability.

[0055] Of course, the shape of the mask 500 can also be adapted to the structure of the thick-walled part 300, and the mask 500 can also be a two-color mask to present a unique appearance.

[0056] The inner and outer surfaces of the mask 500 can also be optically textured to further homogenize the light output or reduce glare.

[0057] This solution also includes a lower decorative ring 410 and an upper decorative ring 420 as decorative elements, used for appearance design and fixed support. The lower decorative ring 410 and the upper decorative ring 420 are respectively disposed on the first layer of thick wall 310 and the second layer of thick wall 320 of the thick wall member 300.

[0058] Furthermore, the bottom surface of the first thick wall 310 has an extended edge, on which a first mounting hole is provided. The lower decorative ring 410 and the circuit board 200 are respectively connected to the first mounting hole of the first thick wall 310 and the housing 100 by hot riveting.

[0059] The upper surface of the second thick wall 320 is provided with a second mounting hole, and the upper decorative ring 420 is connected to the second mounting hole of the second thick wall 320 by bolts.

[0060] The circuit board 200 and the lower trim ring 410 are fixed to the thick-walled component 300 by heat riveting, and then fixed to the housing 100 by screws. The upper trim ring 420 is connected to the thick-walled component 300 by screws. Finally, the faceplate 500 is connected to the housing 100 by welding to form the complete lamp. The control signal is transmitted to the control components of the circuit board 200 through an automotive-grade connector to realize the switching of the headlight.

[0061] In a specific embodiment, the thick-walled component 300 is a thick-walled component made of a plastic material with high light transmittance. For example, polycarbonate (PC) or acrylonitrile-butadiene-styrene copolymer (ABS) can be molded in one step by injection molding and has good optical properties and processability.

[0062] The light propagation path of the vehicle's through-beam lamp in this design is as follows:

[0063] 1. First Reflection: Light emitted from the light source enters the interior of the thick-walled member 300 through the bottom surface 330 of the first thick-walled member 310. The light propagates within the thick-walled member 300, first reaching the inner surface of the first thick-walled member 310. Because the inner surface of the first thick-walled member 310 has a textured surface, it is configured to perform total internal reflection on most of the incident light, changing the light path and guiding it to the outer surface of the first thick-walled member 310.

[0064] 2. Second reflection: Light rays reaching the outer surface of the first thick wall 310 undergo total internal reflection due to the patterned surface on that surface. This reflection directs the light rays to the bottom surface of the second thick wall 320.

[0065] 3. Light path reversal: Light enters the second thick wall 320 through the bottom surface of the second thick wall 320 and propagates to the inner surface of the second thick wall 320.

[0066] 4. Third reflection: The inner surface of the second thick wall 320 is also provided with a patterned surface, which will reflect the received light again and guide the light path to the final light-emitting surface, that is, the outer surface of the second thick wall 320.

[0067] 5. Uniform light emission: The light reaches the outer surface of the second thick wall 320. Since this light-emitting surface is also patterned, its main function is to scatter and homogenize the light, eliminate local bright spots, and make the light emitted from this surface visually uniform and soft, forming a light band with uniform brightness and no dark areas.

[0068] The beneficial effects of the technical solution provided by this utility model include:

[0069] Through a unique Z-shaped double-layer thick-walled structure and side pattern design, light emitted from point or line light sources is transformed into a uniform and bright linear light band after three main reflections and one scattering. This structure enables the light path to fold and turn within a limited space, allowing the through-light to maintain an ultra-thin appearance while ensuring extremely high light uniformity and a sophisticated visual effect. Furthermore, the one-piece molded thick-walled component simplifies the assembly process and reduces production costs.

[0070] In addition, this utility model also provides a vehicle, including the vehicle through light in the above specific embodiment.

[0071] Obviously, vehicles that include the aforementioned vehicle-through lights have the same beneficial effects, which will not be elaborated upon here.

[0072] The vehicle's through light can be installed at the front or rear of the vehicle, depending on the specific needs.
