Description
Technical Field
[0001] This utility model relates to the field of automotive lighting technology, specifically to a uniformly emitting automotive front through-light structure and an automotive. Background Technology
[0002] With the popularization of new energy vehicles and intelligent vehicles, the design of car front ends is gradually evolving towards a "minimalist and technological" style. The front continuous light, as a core design element to enhance the overall vehicle's recognizability and futuristic feel, is integrated with the body lines and headlight assembly, and is widely used. Light guides, due to their advantages such as low cost and small structural space occupation, have become one of the options for front continuous lights. In existing light guide solutions, the light guide is arranged along the Y-axis (or the transverse direction of the vehicle body) at the front of the car. Since the headlight assemblies on both sides of the front of the car occupy part of the Y-axis space, there is not enough space for the light sources at both ends of the light guide in the Y-axis. Therefore, the light sources at both ends of the light guide can only be arranged in the X-axis (or the longitudinal direction of the vehicle body) behind the headlights. The two ends of the light guide also form a backward-bending inclined section to accommodate the position of the light source. In order to obtain a better light output effect, the bending points at both ends of the light guide are rounded, and the light guide as a whole has a U-shaped structure with the opening gradually increasing. There is also a decorative piece along the Y-axis on the front side of the light guide. The decorative piece is translucent. The light emitted by the light source enters the light guide from the end faces of both ends of the light guide and then exits from the front side of the light guide to the decorative piece. The light shines out after passing through the decorative piece. The inclined section at both ends of the light guide is far away from the two ends of the decorative piece. The light output from the inclined section to the two ends of the decorative piece is insufficient, resulting in obvious dark areas at both ends of the front through-light and poor light output uniformity. Utility Model Content
[0003] The first objective of this utility model is to address the problem in the prior art where the light output from both ends of the front through-beam light guide to the decorative parts is insufficient, resulting in obvious dark areas at both ends of the front through-beam light and poor light uniformity, by providing a structure for a front through-beam light with uniform light output; the second objective of this utility model is to provide a vehicle.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A uniformly emitting automotive front through-light structure includes a light guide, a decorative element, and two light source assemblies. Both the decorative element and the light guide are arranged laterally at the front end of the vehicle, with the decorative element located in front of the light guide. Both ends of the light guide have rearward-bending inclined sections. Light from the two light source assemblies enters the light guide from the end faces at both ends. A dark area compensation element is provided between any inclined section and the end of the decorative element. The dark area compensation element includes a light-emitting part located at the front and a light-incoming part located at the rear, with the light-incoming part connected to the inclined section. Some light rays in the light guide can enter the dark area compensation element from the light-incoming part and then exit from the light-emitting part to the end of the decorative element.
[0006] The present invention, employing the aforementioned technical solution, connects a dark area compensation component to each of the inclined sections at both ends of the existing light guide. The dark area compensation component is located between the inclined section and the end of the decorative component, allowing some light from the light guide to be introduced and then emitted from the front light-emitting part. At the same time, the light-emitting part is closer to the end of the decorative component, thus increasing the light output at both ends and reducing or eliminating the dark areas at both ends. Compared with the problem in the prior art where the light output from both ends of the automotive front through-light guide to the decorative component is insufficient, resulting in obvious dark areas at both ends of the front through-light and poor light output uniformity, the present invention increases the light output from both ends of the light guide to the decorative component by adding dark area compensation components at both ends of the light guide, reducing or eliminating the dark areas at both ends of the front through-light, and achieving better light output uniformity.
[0007] Furthermore, the light-emitting section is a strip structure arranged laterally; with this configuration, the light-emitting section of the dark area compensation component can cover a larger lateral width, resulting in a better lighting effect on the dark area.
[0008] Furthermore, the light-emitting section is strip-shaped; the light-inlet section includes a first light-inlet section and a second light-inlet section, both of which are strip-shaped, and their rear ends are respectively connected to the inclined section; in the transverse direction, the first light-inlet section is located outside the second light-inlet section; the front end of the first light-inlet section is provided with a V-shaped branch structure, including a first branch and a second branch, the end of the first branch is connected to the middle of the second light-inlet section, and the end of the second branch is connected to the end of the light-emitting section; the front end of the second light-inlet section is connected to the middle of the light-emitting section; the dark area compensation component of the above shape is generally multi-strip and multi-branch shape. With this arrangement, some of the light rays in the light guide can be split into multiple sub-light paths, which are then reflected and refracted to the dark areas at both ends, so that the light energy can be more evenly distributed to the entire light-emitting section, thereby reducing or eliminating the dark areas at both ends.
[0009] Furthermore, the dark area compensation component is a plate-shaped structure; the plate-shaped dark area compensation component has a relatively regular structure and is easy to manufacture.
[0010] Furthermore, the light guide and the dark area compensation component are integrally injection molded; the light guide and the dark area compensation component are interconnected and are both light guide components, which are obtained by integral injection molding, making the manufacturing simple.
[0011] Furthermore, the light source assembly includes a PCB board and a plurality of LEDs disposed on the PCB board, with the LEDs facing the end face of the light guide and the PCB board fixed to the end of the light guide.
[0012] To achieve the second objective, the present invention adopts the following technical solution:
[0013] An automobile includes the aforementioned uniformly emitting through-beam headlight structure.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by adding dark area compensation components at both ends of the light guide, this utility model increases the amount of light emitted from both ends of the light guide to the decorative component, reduces or eliminates the dark areas at both ends of the front through-light, and achieves better light emission uniformity; the car has the same technical effect as the aforementioned uniform light emission car front through-light structure.

Figures 1-3 The system includes a light guide 1, a decorative element 2, and two light source assemblies. Both the decorative element 2 and the light guide 1 are arranged laterally at the front end of the vehicle, with the decorative element 2 positioned in front of the light guide 1. Both ends of the light guide 1 have rearward-bending inclined sections 3. Light from the two light source assemblies enters the light guide 1 from its end faces. A dark area compensation element 4 is provided between any inclined section 3 and the end of the decorative element 2. The dark area compensation element 4 includes a light-emitting section 5 located at the front and a light-incoming section located at the rear, with the light-incoming section connected to the inclined section 3. Some light from the light guide 1 can enter the dark area compensation element 4 from the light-incoming section and then exit from the light-emitting section 5 to the end of the decorative element 2. Both the light guide 1 and the dark area compensation element 4 are made of polycarbonate (PC) plastic. The light guide 1 and the dark area compensation element 4 are integrally injection molded. Note that the vehicle headlight is not shown in the figure; the dark area compensation element 4 is located in the gap area between the headlight and the light guide 1 and will not affect the installation of the headlight.
[0022] The dark area compensation component 4 has a plate-like structure; the light emitting part 5 is strip-shaped and arranged laterally; the light receiving part includes a first light receiving part 6 and a second light receiving part 7, both of which are strip-shaped, and their rear ends are respectively connected to the inclined section 3; in the transverse direction, the first light receiving part 6 is located outside the second light receiving part 7; the front end of the first light receiving part 6 is provided with a V-shaped branch structure, including a first branch 8 and a second branch 9, the end of the first branch 8 is connected to the middle of the second light receiving part 7, and the end of the second branch 9 is connected to the end of the light emitting part 5; the front end of the second light receiving part 7 is connected to the middle of the light emitting part 5;
[0023] The light source assembly includes a PCB board 10 and several LEDs disposed on the PCB board 10. The LEDs face the end face of the light guide 1, and the PCB board 10 is fixed to the end of the light guide 1.
[0024] The present invention, employing the aforementioned technical solution, connects a dark area compensation component 4 to each of the inclined sections 3 at both ends of the existing light guide 1. The dark area compensation component 4 is located between the inclined section 3 and the end of the decorative component 2, allowing some light from the light guide 1 to be introduced and then emitted from the light-emitting part 5 on the front side. At the same time, the light-emitting part 5 is closer to the end of the decorative component 2, thus increasing the amount of light emitted at both ends, thereby reducing or eliminating the dark areas at both ends. Compared with the problem in the prior art where the amount of light emitted from both ends of the automotive front through-light guide to the decorative component is insufficient, resulting in obvious dark areas at both ends of the front through-light and poor light emission uniformity, the present invention increases the amount of light emitted from both ends of the light guide to the decorative component by adding dark area compensation components at both ends of the light guide, reducing or eliminating the dark areas at both ends of the front through-light, and achieving better light emission uniformity.
