Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of automobile accessories, and in particular to a license plate light assembly and a vehicle. Background Art
[0002] In recent years, my country's automotive industry has experienced rapid growth, and the automotive industry remains a core development trend in the future. With the continuous advancement of technology and the continuous improvement of people's living standards, the demand for automotive performance is also increasing. License plates are typically mounted on the exterior surfaces of the front and rear of a vehicle. License plate lights illuminate the plates at night or in dark conditions. Regulations require that all vehicles operate with rear license plate lights on at night. The brightness of the rear license plate lights must ensure that the license plate number can be clearly seen within 20 meters of normal night vision. Therefore, maintaining the functional protection of a vehicle's license plate lights is crucial.
[0003] The quality of automotive lighting is crucial to driving safety. Lighting design must not only meet regulatory safety requirements but also satisfy other requirements, such as an aesthetically pleasing, practical, and aerodynamically pleasing design that blends seamlessly with the vehicle's overall appearance. License plate lights, used to illuminate the license plate, are ideal for use at night or during dim daylight hours. In the event of an accident, traffic police can identify the vehicle's license plate from both sides and identify the responsible driver. Current license plate lights typically feature two bulbs, inserted into sockets with sealing rings within the housing. The sockets are located on the left and right sides of the upper portion of the license plate, illuminating the area beneath the light.
[0004] However, most current cars have two license plate lights. When a car is equipped with only one license plate light, it may not meet the legal requirements for license plate light distribution. When the license plate light is illuminated, the area directly facing the light is very bright, while the rest of the plate (such as the corners) is very dark. This results in different light distribution intensities and uniformity across the plate, making it difficult for the human eye to see the license plate number at night. In the event of a traffic accident, the inability to clearly see the license plate number can make it difficult for traffic police to identify the vehicle involved, hindering the investigation of the case. Summary of the Invention
[0005] An embodiment of the present application provides a license plate light assembly and a vehicle. By adding a special-shaped structure inside the light-transmitting cover, the lighting path and light intensity of the license plate light are changed, so that the light intensity of the license plate farther away from the license plate light is enhanced, meeting the legal requirements for the brightness of the license plate, and reducing the brightness of the light directly below the license plate light. The difference between the brightness directly below the license plate light and the brightness of other positions on the license plate is reduced, thereby ensuring uniform light distribution.

[0058] As described in the background, the number of license plate lamps of most vehicles at the present stage is usually two. When a vehicle is arranged with only one license plate lamp, the license plate lamp may not meet the requirements of license plate light distribution regulations. When the license plate lamp emits light, the light of the part of the license plate directly opposite to the license plate lamp is very bright, while the rest of the license plate (such as the corners) is very dark, so that the light intensity and uniformity of the license plate are different, and thus the license plate number cannot be clearly seen by the human eye at night. When a traffic accident occurs, the failure to clearly see the license plate number makes it difficult for the traffic police to find the vehicle causing the accident, which affects the handling of the case.
[0059] To solve the above technical problems, the embodiment of the present application provides a license plate lamp assembly and a vehicle. The license plate lamp assembly comprises a license plate lamp, a shell and a light-transmitting cover. The license plate lamp is located inside the shell, and the light-transmitting cover is located below the license plate lamp. The light-transmitting cover comprises a special-shaped structure, which is located below the license plate lamp and is used for diffusing the light source emitted by the license plate lamp. The special-shaped structure comprises a pattern structure, which is used for diffusing the light emitted by the license plate lamp to the area directly below the license plate lamp. The vehicle comprises a vehicle body, a license plate and the license plate lamp assembly. The license plate and the license plate lamp assembly are located on the outer side of the vehicle body, and the license plate lamp assembly is located above the license plate. In this way, the embodiment of the present application can increase the structure inside the light-transmitting cover through the license plate lamp, change the illumination path and light intensity of the license plate lamp, increase the light intensity of the license plate far away from the license plate lamp, meet the brightness requirements of the license plate, reduce the light intensity directly below the license plate lamp, reduce the difference between the brightness directly below the license plate lamp and the brightness of other positions of the license plate, and ensure the light distribution uniformity.
[0060] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0061] Embodiments of the present invention provide a license plate light assembly and vehicle. By adding a structure within the light-transmitting cover of the license plate light, the license plate light's illumination path and light intensity are modified. This enhances the light intensity of license plates farther from the light, thus meeting regulatory brightness requirements for license plates. The specific structures of the license plate light assembly and vehicle provided by the embodiments of this application are described below, with reference to the accompanying drawings.
[0062] refer to Figure 1 as well as Figure 2 According to a first aspect of an embodiment of the present invention, a license plate light assembly 100 is provided, which may include a license plate light 200, a housing 300, and a light-transmitting cover 400. The license plate light 200 may be located inside the housing 300, and the light-transmitting cover 400 may be located under the license plate light 200. In one possible implementation, the housing 300 may be a rectangular shell, and the present invention does not limit the shape of the housing 300. In an embodiment of the present application, the light-transmitting cover 400 may include a special-shaped structure 500. The special-shaped structure 500 may be located under the license plate light 200. It can be understood that the special-shaped structure 500 can be used to disperse the light source emitted by the license plate light 200.
[0063] refer to Figure 2 as well as Figure 3 The special-shaped structure 500 may include a recessed structure 510 . The recessed structure 510 may be formed on a side of the light-transmitting cover 400 opposite to the license plate light 200 . In one possible implementation, the recessed structure 510 may be located directly below the license plate light 200 .
[0064] Continue to refer Figure 2 as well as Figure 3Based on the above embodiment, the recessed structure 510 may further include a concave surface structure 520. At least a portion of the concave surface of the concave surface structure 520 may be positioned toward the license plate light 200. Accordingly, the concave surface structure 520 may be located below the license plate light 200. In one possible implementation, the concave surface structure 520 may further include a first concave surface 521 and a second concave surface 522. The first and second concave surfaces 521, 522 may be arc-shaped, with the arcs of the first and second concave surfaces 521, 522 facing the side with the license plate light 200. In this embodiment of the present application, the first and second concave surfaces 521, 522 may be connected front to back in the width direction of the special-shaped structure 500. The point where the first and second concave surfaces 521, 522 connect may protrude from the entire concave structure 520. Alternatively, the point where the first and second concave surfaces 521, 522 connect may not protrude from the entire concave structure 520. In some other embodiments, the concave structure 520 may also be a continuous arc surface. Additionally, the concave structure 520 may also be a pit with no openings on both sides in the width direction of the special-shaped structure 500 .
[0065] Based on the above embodiments, continue to refer to Figure 3 In one possible implementation, the shape and size of the concave structure 520 can be adjusted based on the relative distance between the license plate light 200 and the license plate 820 illuminated by the license plate light 200. For example, when the license plate light 200 is farther away from the license plate 820, the distance between the arc surface of the concave structure 520 and the license plate light 200 can be increased accordingly, thereby enhancing the brightness of the license plate 820. Therefore, the present invention does not impose any restrictions on the shape and size of the concave structure 520.
[0066] Continue to refer Figure 2 Based on the above embodiment, the special-shaped structure 500 may further include an inclined surface structure 530. The inclined surface structure 530 may further include a first inclined surface 531 and a second inclined surface 532. In one possible implementation, the first inclined surface 531 and the second inclined surface 532 may be located on either side of the concave structure 520 along the length of the special-shaped structure 500. This gives the entire special-shaped structure 500 a trapezoidal appearance, allowing the light emitted by the license plate light 200 to diverge to the sides, thereby increasing the intensity of the scattered light.
[0067] Continue to refer Figure 2 Based on the above embodiment, the bottom of the concave structure 510 can extend in an M-shape toward the inclined structures 530 on both sides of its length. In this way, while ensuring that the concave structure 510 disperses the light source, the inclined structures 530 can achieve good light transmittance on both sides, allowing the light source to be further dispersed in all directions.
[0068] Continue to refer Figure 2 Based on the above embodiment, the height of the inclined structure 530 at the end away from the concave structure 520 can be less than or equal to the height of the inclined structure 530 at the end closer to the concave structure 520. In one possible implementation, the special-shaped structure 500 can be a trapezoidal structure with a thicker center and gradually thinner sides. That is, the thickness of the inclined structure 530 near the center should be greater than or equal to the thickness of the inclined structure 530 near the ends. In this way, because the thickness of the two sides of the special-shaped structure 500 is smaller, the light transmittance on both sides is better. The light emitted by the license plate light 200 can be dispersed to the sides instead of being concentrated directly below the license plate light 200. This enhances the light intensity of the license plate 820 below the license plate light 200, thereby meeting the intensity and uniformity of the light distribution of the license plate light 200.
[0069] Continue to refer Figure 2 as well as Figure 3 Based on the above embodiment, the light-transmitting cover 400 may further include a light coupling structure 600. The light coupling structure 600 may be located above the special-shaped structure 500 and directly below the license plate light 200. It is understood that the light coupling structure 600 can be used to diffusely reflect light from the license plate light 200 directly below the license plate light 200, thereby weakening the light intensity in the area directly below the license plate light 200 and causing the light to diverge to the sides.
[0070] Based on the above embodiment, the light coupling structure 600 can be formed by surface structuring. In one possible implementation, the surface structuring can be formed by at least one of the following methods: mechanical structuring; embossing; etching; and spraying. The embodiments of the present application are not limited to the surface structuring method.
[0071] Based on the above embodiment, the light coupling structure 600 can be formed by embedding light scattering particles in the light-transmitting cover 400. Figure 3 Based on the above embodiment, the light coupling structure 600 may include a granular structure 610. In one possible implementation, the number of granular structures 610 may be multiple, and the present invention does not limit the number of granular structures 610. In the embodiment of the present application, the multiple granular structures 610 on the light coupling structure 600 may have different angles. It is understood that the size of the granular structure 610 in the light coupling structure 600 can be adjusted according to the light distribution requirements. Of course, in some other embodiments, the light coupling structure 600 may also include a patterned structure, wherein the patterned structure may be protrudingly provided on the light coupling structure 600, and the shape of the patterned structure is not limited.
[0072] On the basis of the above-mentioned embodiment, the optical coupling structure 600 can have the effect of diffuse reflection of light by providing a plurality of granular structures 610. It should be noted that diffuse reflection is the phenomenon in which light projected on a rough surface is reflected in all directions. When a beam of parallel incident light hits a rough surface, the surface will reflect the light in all directions. Therefore, although the incident rays are parallel to each other, the normal directions of each point are inconsistent, causing the reflected light to be irregularly reflected in different directions. In this way, the granular structure 610 can achieve a diffuse reflection effect on the light irradiated by the license plate light 200, which can weaken the light intensity directly below the license plate light 200, improve the brightness uniformity of the license plate light 200 irradiated on the surface of the license plate 820, and meet the legal requirements for brightness uniformity on the surface of the license plate 820.
[0073] Continue to refer Figure 1 as well as Figure 2 Based on the above embodiment, the special-shaped structure 500 and the light coupling structure 600 can be integrally formed. In one possible implementation, the special-shaped structure 500, the light coupling structure 600, and the light-transmitting cover 400 can be integrally molded using a mold injection molded from polymethyl methacrylate (PMMA). Of course, in other embodiments, the special-shaped structure 500 and the light coupling structure 600 can also be separate structures, with the light coupling structure 600 being attached to the surface of the special-shaped structure 500.
[0074] Continue to refer Figure 2 Based on the above embodiment, the license plate light assembly 100 may further include a circuit board 700. In one possible implementation, the circuit board 700 may be located above the license plate light 200 and electrically connected to the license plate light 200. It is understood that the circuit board 700 may be used to provide a stable power supply voltage and current to the license plate light 200, enabling the license plate light 200 to emit light and ensure normal operation.
[0075] Continue to refer Figure 1 Based on the above embodiment, the license plate light assembly 100 may further include a connector 310. The connector 310 may be located at one end of the housing 300. It is understood that the connector 310 can be used to electrically connect the license plate light assembly 100 to the vehicle 800 to facilitate signal transmission. In one possible implementation, the vehicle 800 may have a plug interface that matches the connector 310, allowing the connector 310 to connect to the vehicle 800 via the plug interface.
[0076] Continue to refer Figure 1Based on the above embodiment, the license plate light assembly 100 may further include a sealing ring 320. In one possible implementation, the sealing ring 320 may be disposed outside the light-transmitting cover 400. It is understood that the sealing ring 320 can be used to provide waterproofing and sealing for the light-transmitting cover 400.
[0077] Continue to refer Figure 1 Based on the above embodiment, the license plate light assembly 100 may further include a spring leaf 330. In one possible implementation, the spring leaf 330 may be located at one end of the housing 300, and may be located at an end away from the connector 310. It is understood that the spring leaf 330 can be used to provide a certain elastic force to assist in bearing the load.
[0078] refer to Figure 4 A second aspect of an embodiment of the present invention provides a vehicle 800, which may include a vehicle body 810, a license plate 820, and the above-mentioned license plate light assembly 100. The license plate 820 and the license plate light assembly 100 may be located on the outside of the vehicle body 810. In an embodiment of the present application, the license plate light assembly 100 may be located on the license plate 820. In one possible implementation, the license plate light assembly 100 may be located at any position on the license plate 820, and the present invention does not limit the position of the license plate light assembly 100.
[0079] In this embodiment of the present application, a special-shaped structure 500 and a light coupling structure 600 are designed within the light-transmitting cover 400. The special-shaped structure 500 is designed to have an uneven thickness, and can be based on a trapezoidal structure with a thicker center and gradually tapering to thinner sides. Furthermore, a concave structure 520 is provided directly below the license plate light 200, facing the end where the license plate light 200 resides. The shape and dimensions of the concave structure 520 can be adjusted based on the relative position and distance between the license plate light 200 and the license plate 820 it illuminates. The concave structure 520 allows the light from the license plate light 200 to diverge to the sides, rather than being concentrated directly below the license plate light 200. This enhances the light intensity on both sides of the license plate 820 below the license plate light 200, meeting regulatory requirements for surface light intensity on the license plate 820. The light coupling structure 600 is disposed on the special-shaped structure 500. Specifically, the light coupling structure 600 can be disposed on the surface of the concave structure 520. The multiple granular structures 610 in the light coupling structure 600 can diffusely reflect light, further reducing the intensity of light directly below the license plate light 200. This improves the brightness uniformity of the license plate 820 illuminated by the license plate light 200, meeting regulatory requirements for brightness uniformity on the license plate 820 surface.
[0080] Conventional vehicles 800 typically require two license plate lights 200. If only one license plate light 200 is installed on a vehicle 800, the regulatory requirements for license plate light 200's lighting distribution may not be met. In the present embodiment, while only one license plate light 200 is provided, the brightness and uniformity of the license plate 820 are still met. This not only saves installation space and reduces the number of license plate lights 200 on the vehicle 800, thereby lowering the overall vehicle cost. Furthermore, the lighting path and light intensity of the license plate light 200 are modified, meeting the regulatory brightness requirements for the license plate 820 and ensuring uniform lighting distribution.
