[0003] Currently, most electric vehicle position lights or turn signals use thick-walled components to achieve dynamic or interactive effects. The main optical forms are direct and reflective. Considering optical efficiency and effect, conventional direct and reflective types require a large space, resulting in a larger thickness of the thick-walled components, which in turn increases their weight. Utility Model Content
[0004] To address at least one of the problems mentioned in the background art, this application provides an optical structure for automotive lighting and an electric vehicle that can reduce the weight of the lighting fixture.
[0005] To achieve the above objectives, this application provides the following technical solution:
[0006] In a first aspect, this application provides an automotive lamp optical structure, including a thick-walled lamp component, a lamp holder, and a lamp. The thick-walled lamp component is a light-transmitting component, and the thick-walled lamp component includes a first side and a second side that are positioned opposite each other. The first side forms a light-incident unit, which includes an adjacent light-incident surface and a total reflection surface. The second side forms a light-emitting surface.
[0007] The headlight is mounted on a lamp holder. The light emitted by the headlight is refracted by the light incident surface and enters the thick-walled part of the headlight. The height of the headlight is no higher than the upper surface of the thick-walled part of the headlight. The total reflection surface is constructed to reflect the light refracted into the thick-walled part of the headlight to the light exiting surface, and then refract the light out of the thick-walled part of the headlight.
[0008] As an alternative implementation, the lamp holder is mounted on the upper surface of the thick-walled component, and the vehicle lamp is located on the lower surface of the lamp holder.
[0009] As an optional implementation, the light-incident surface is an arc surface, the total reflection surface is an inclined surface, the upper end of the light-incident surface is connected to the upper surface of the thick-walled component, the lower end of the light-incident surface is connected to the upper end of the total reflection surface, and the lower end of the total reflection surface is connected to the lower surface of the thick-walled component.
[0010] As an optional implementation, the angle between the tangent at the lower end of the incident surface and the total reflection surface is 85°-90°.
[0011] As an optional implementation, there are multiple light-incident units and vehicle lights. The multiple light-incident units are distributed at intervals on the first side of the thick-walled component of the vehicle light. The number of vehicle lights is the same as the number of light-incident units, and the vehicle lights and light-incident units are arranged in a one-to-one correspondence.
[0012] As an alternative implementation, the first side of the thick-walled member also has a fixing structure for fixing it to the frame.
[0013] As an alternative implementation, the upper surface of the thick-walled component of the vehicle lamp has a connector, and the lamp holder is mounted on the upper surface of the thick-walled component through the connector.
[0014] As an alternative implementation, the total reflection surface has multiple arrays of protruding structures.
[0015] As an optional implementation, the thickness of the thick-walled component of the headlight is 4mm-5mm.
[0016] Secondly, this application also provides an electric vehicle, including the headlight optical structure described in the first aspect.
[0017] The automotive lamp optical structure provided in this application includes a thick-walled lamp component, a lamp holder, and a lamp. The thick-walled lamp component is a light-transmitting component, comprising a first side and a second side positioned opposite each other. The first side forms a light-incident unit, which includes an adjacent light-incident surface and a total reflection surface. The second side forms a light-emitting surface. The lamp is mounted on the lamp holder. The light emitted by the lamp is refracted through the light-incident surface and enters the thick-walled lamp component. The height of the lamp is no higher than the upper surface of the thick-walled lamp component. The total reflection surface is configured to completely reflect the light refracted into the thick-walled lamp component towards the light-emitting surface, and then refract it out of the thick-walled lamp component. In the automotive lamp optical structure provided in this application, the lamp, as a light source, first refracts the light emitted through the light-incident surface into the thick-walled lamp component. The light refracted into the thick-walled component is then completely reflected by the total reflection surface towards the light-emitting surface, and finally refracted out of the thick-walled lamp component. This light path design requires significantly less space compared to traditional direct and reflective types, effectively reducing the thickness of the headlight's thick-walled components and achieving lightweight lighting. Simultaneously, the optimized design of the light-incident surface and total reflection surface allows the light source to be positioned closer to the light-incident surface, resulting in a more compact optical structure and further improving space utilization while maintaining optical performance.

[0031] Currently, most electric vehicle position lights or turn signals use thick-walled components to achieve dynamic or interactive effects. The main optical forms are direct and reflective. Considering optical efficiency and effect, conventional direct and reflective types require a large space, resulting in a larger thickness of the thick-walled components, which in turn increases their weight.
[0032] In view of this, this application provides an automotive lamp optical structure, including a thick-walled lamp component, a lamp holder, and a lamp. The thick-walled lamp component is a light-transmitting component, comprising a first side and a second side positioned opposite each other. The first side forms a light-incident unit, which includes an adjacent light-incident surface and a total reflection surface. The second side forms a light-emitting surface. The lamp is mounted on the lamp holder. The light emitted by the lamp is refracted through the light-incident surface and enters the thick-walled lamp component. The height of the lamp is no higher than the upper surface of the thick-walled lamp component. The light emitted by the lamp is first refracted through the light-incident surface into the thick-walled lamp component. The refracted light entering the thick-walled component is then totally reflected by the total reflection surface towards the light-emitting surface, and finally refracted out of the thick-walled lamp component by the light-emitting surface. This light path design, compared to traditional direct and reflective types, significantly reduces the required space, thereby effectively reducing the thickness of the thick-walled lamp component and achieving lightweighting of the lamp.

[0034] You can refer to this. Figures 1 to 5This application provides a vehicle lamp optical structure 100, including a thick-walled lamp member 110, a lamp holder 120, and a lamp 130. The thick-walled lamp member 110 is a light-transmitting member and includes a first side and a second side that are positioned opposite each other. A light-incident unit 140 is formed on the first side, and the light-incident unit 140 includes an adjacent light-incident surface 141 and a total reflection surface 142. A light-emitting surface 111 is formed on the second side. The lamp 130 is disposed on the lamp holder 120. The light emitted by the lamp 130 enters the thick-walled lamp member 110 after being refracted by the light-incident surface 141. The height of the lamp 130 is not higher than the upper surface of the thick-walled lamp member 110. The total reflection surface 142 is configured to reflect the light refracted into the thick-walled lamp member 110 to the light-emitting surface 111 and refract it out of the thick-walled lamp member 110 through the light-emitting surface 111.
[0035] The automotive lamp optical structure 100 provided in this embodiment uses a lamp 130 as the light source. The emitted light is first refracted through the light-incident surface 141 into the thick-walled lamp component 110. The light refracted into the thick-walled component is then totally reflected by the total reflection surface 142 towards the light-emitting surface 111, and finally refracted out of the thick-walled lamp component 110 by the light-emitting surface 111. This light path design, compared to traditional direct and reflective types, requires significantly less space, thereby effectively reducing the thickness of the thick-walled lamp component 110 and achieving lightweighting of the lamp. At the same time, through the reasonable design of the light-incident surface 141 and the total reflection surface 142, the light source can be placed closer to the light-incident surface 141, making the automotive lamp optical structure 100 more compact and further improving space utilization while ensuring optical performance.
[0036] In the above embodiments, the lamp holder 120 can be installed on the upper surface of the thick-walled component, and the vehicle lamp 130 is located on the lower surface of the lamp holder 120. It is understandable that the design of mounting the lamp holder 120 on the upper surface of the thick-walled component and the headlight 130 on the lower surface of the lamp holder 120, combined with the collaborative structure of the light-incident surface 141 and the total reflection surface 142, allows the light emitted by the headlight 130 to be incident perpendicularly or at a small angle onto the light-incident surface 141. After refraction, the light enters the thick-walled component and is guided by the total reflection surface 142 to the light-emitting surface 111. On the one hand, this optimizes the light path, shortens the optical path, and reduces the space redundancy required for optical propagation, thereby reducing the thickness of the thick-walled component 110 and effectively reducing the weight of the plastic part to meet the lightweight development requirements of electric vehicles. On the other hand, this mounting layout allows the light source (headlight 130) to be closer to the light-incident surface 141, improving the light-incident efficiency, reducing light loss, and ensuring stable optical performance. At the same time, the assembly method of the lamp holder 120 and the upper surface of the thick-walled component simplifies the assembly process and improves the structural integration. Furthermore, the headlight 130 is hidden on the lower surface of the lamp holder 120, which avoids direct interference from the external environment to the light source, improving structural protection and service life.
[0037] In the above embodiment, the light-incident surface 141 can be an arc surface, and the total reflection surface 142 is an inclined surface. The upper end of the light-incident surface 141 connects to the upper surface of the thick-walled component, and the lower end connects to the upper end of the total reflection surface 142. The lower end of the total reflection surface 142 connects to the lower surface of the thick-walled component. It can be understood that by designing the light-incident surface 141 as an arc surface and the total reflection surface 142 as an inclined surface, with the upper end of the light-incident surface 141 connecting to the upper surface of the thick-walled component and the lower end connecting to the upper end of the total reflection surface 142, and the lower end of the total reflection surface 142 connecting to the lower surface of the thick-walled component, an integrated light-guiding channel of "upper surface - arc surface light-incident - inclined surface total reflection - lower surface" can be formed. The arc surface light-incident surface 141 can expand the light receiving range, improve the refraction adaptability of incident light at different angles, and reduce the impact of installation deviations of the light source (vehicle lamp 130). To reduce incident light loss, the layout of the lamp holder 120 mounted on the upper surface of the thick-walled component and the vehicle lamp 130 located on the lower surface of the lamp holder 120 allows the light from the vehicle lamp 130 to be incident on the curved light-incident surface 141 at a vertical or small angle with high efficiency. After precise refraction, the light is guided to the inclined total internal reflection surface 142. The inclined total internal reflection surface 142, through precise connection with the light-incident surface 141 and the lower surface of the thick-walled component, can preset the optimal reflection angle according to the principle of optical total internal reflection, so as to guide the light to the light-exiting surface 111 in a directional manner, avoid light scattering, and improve optical efficiency.
[0038] Meanwhile, the integrated connection structure eliminates redundant space inside the thick-walled component, significantly shortens the optical path, and promotes further reduction in the thickness of the thick-walled component, helping to realize lightweight design. In addition, the smooth connection between the curved surface and the inclined surface, as well as the integrated structure with the upper and lower surfaces of the thick-walled component, improves the structural integrity and mechanical stability of the thick-walled component, reduces stress concentration, simplifies the mold forming process, and reduces production errors. At the same time, the seamless connection between the light-incident surface 141 and the total reflection surface 142 can avoid additional light loss at the interface.
[0039] In the above embodiments, the angle between the tangent at the lower end of the light-incident surface 141 and the total internal reflection surface 142 can be 85°-90°. It can be understood that setting the angle between the tangent at the lower end of the light-incident surface 141 and the total internal reflection surface 142 to 85°-90°, combined with the curved surface characteristics of the light-incident surface 141 and the inclined surface structure of the total internal reflection surface 142, allows for precise control of the angle matching relationship between light refraction and total internal reflection. This angle range ensures that the light refracted by the curved light-incident surface 141 can reach the total internal reflection surface 142 at an incident angle that meets the conditions for total internal reflection, maximizing the total internal reflection efficiency, avoiding optical loss caused by light refraction penetrating the total internal reflection surface 142, and ensuring the stability and concentration of the directional light guiding to the light-emitting surface 111. Simultaneously, this angle design is compatible with the integrated structure where the upper end of the light-incident surface 141 connects to the upper surface of the thick-walled component, the lower end connects to the upper end of the total internal reflection surface 142, and the lower end of the total internal reflection surface 142 connects to the lower surface of the thick-walled component, enabling precise control of the angle matching between light refraction and total internal reflection. Optimizing the optical path layout within the limited thickness space of the thick-walled component reduces the spatial redundancy of the light guide channel, further contributing to the reduction of the thickness of the thick-walled component to achieve lightweighting. The included angle range of 85°-90° combines optical performance stability with manufacturing process compatibility. It avoids the problem of insufficient light incident angle due to too small an included angle, which would prevent total internal reflection, while also preventing the optical path from being prolonged or the structural stress from being too large. Combining the light-gathering effect of the curved light incident surface 141 with the directional light guiding function of the inclined total internal reflection surface 142, it can significantly improve optical efficiency and light output uniformity. It is also compatible with the layout of the lamp holder 120 being installed on the upper surface of the thick-walled component and the vehicle lamp 130 being located on the lower surface of the lamp holder 120, ensuring that the light from the light source is efficiently incident and then precisely guided out, achieving synergistic optimization of optical performance, lightweight requirements, and structural manufacturability.
[0040] In the above embodiments, there are multiple light-incident units 140 and vehicle lamps 130. The multiple light-incident units 140 are distributed at intervals on the first side of the thick-walled member 110 of the vehicle lamp. The number of vehicle lamps 130 is the same as the number of light-incident units 140. The vehicle lamps 130 and the light-incident units 140 are arranged in a one-to-one correspondence. The design features multiple light-incident units 140 spaced apart on the first side of the thick-walled component 110 of the headlight, each corresponding to a headlight 130. This allows for independent control of the on / off state and brightness changes of each corresponding headlight 130, enabling diverse dynamic interactive optical effects such as flowing lines and gradients, thus meeting the functional requirements of electric vehicle position lights or turn signals. The one-to-one correspondence avoids cross-interference of light from multiple light sources, ensuring uniformity and consistency of light output in each area and improving optical display accuracy. The spaced distribution of multiple light-incident units 140 optimizes the structural stress distribution of the thick-walled component, reduces local structural redundancy, and further supports the lightweighting of the thick-walled component. The modular array layout allows for flexible adjustment of the number and spacing of the light-incident units 140, adapting to the installation requirements of headlights 130 in different vehicle models and improving structural versatility. At the same time, the one-to-one correspondence simplifies the assembly and positioning process, reduces assembly errors during mass production, and improves production efficiency and product consistency.
[0041] In the above embodiments, the first side of the thick-walled component may also have a fixing structure 150, which is used to fix it to the vehicle frame. The design of setting the fixing structure 150 on the first side of the thick-walled component 110 can realize a stable connection between the thick-walled component and the vehicle frame without the need for additional independent fixing brackets, reducing the number of parts and assembly steps, and improving assembly efficiency. The fixing structure 150 and the thick-walled component can be integrally molded, simplifying the overall structural design, reducing the assembly space occupation, and avoiding the increase in weight caused by additional brackets, further contributing to the lightweighting of the lamp. The integrated fixing structure 150 improves the structural stability and reliability of the connection between the thick-walled component and the vehicle frame, effectively resisting vibration and impact during vehicle operation, and ensuring the stability of the optical performance of the lamp 130. The fixing structure 150 is integrated into the first side of the thick-walled component, making reasonable use of the side space, without interfering with the optical function of the light-incident unit 140, realizing the coordinated adaptation of structural layout and optical function, reducing the overall installation complexity, and improving the adaptability of vehicle assembly.
[0042] In the above embodiments, the upper surface of the thick-walled component 110 of the vehicle lamp may have a connector 160, and the lamp holder 120 is mounted on the upper surface of the thick-walled component through the connector 160. The design of the connector 160 on the upper surface of the thick-walled component 110 of the vehicle lamp, and the lamp holder 120 mounted on the upper surface of the thick-walled component via the connector 160, enables precise positioning and assembly of the lamp holder 120 and the thick-walled component, improves the stability of the connection between the two, avoids the lamp holder 120 from shifting due to vehicle vibration, and ensures the correspondence accuracy between the vehicle lamp 130 and the light-incident unit 140. The connector 160 provides a clear assembly benchmark for the installation of the lamp holder 120, simplifies the installation process, reduces assembly difficulty and positioning errors, and improves mass production efficiency. It eliminates the need for complex installation structures on the thick-walled component or the lamp holder 120, reducing the complexity of component processing and weight redundancy, and further contributing to the lightweighting of the lamp. The connector 160 can be flexibly designed according to assembly requirements to adapt to the installation requirements of different specifications of lamp holders 120, improving structural versatility and adaptability. At the same time, the connector 160 can be integrally molded with the thick-walled component, ensuring connection strength and structural reliability, avoiding the risk of loosening caused by additional installation parts, and ensuring the stability of the optical path of the vehicle lamp 130.
[0043] In the above embodiments, the total reflection surface 142 can have multiple arrayed protrusions. The design of multiple arrayed protrusions on the total reflection surface 142 increases its effective reflection area, improves the efficiency of capturing and reflecting refracted light, and avoids light scattering loss. The arrayed protrusions can perform zoned and directional reflection of light, ensuring that light from different areas is guided to the light-emitting surface 111 along a preset path, significantly improving light uniformity and display accuracy. The array layout of the protrusions optimizes the optical control capability of the total reflection surface 142, adapts to the light guiding requirements of multiple light-incident units 140, ensures independent and precise light output from each corresponding light source, and enhances the presentation of dynamic interactive effects. Simultaneously, the protrusions and the total reflection surface 142 are integrally molded, achieving fine-grained light control without additional optical components, reducing component redundancy, and not significantly increasing the thickness of thick-walled parts, thus balancing optical performance optimization and lightweight requirements. Furthermore, the arrayed protrusions can disperse internal stress in thick-walled parts, improving structural mechanical stability, and facilitating demolding during mold forming, reducing manufacturing process difficulty.
[0044] In the above embodiments, the thickness of the thick-walled component 110 of the vehicle lamp (the distance between the upper and lower surfaces) can be 4mm-5mm. Within this thickness range, the complete light guiding path after refraction and total reflection can be ensured, while the redundant space of the structure can be compressed to the maximum extent. Compared with traditional thick-walled components, it is significantly thinner, achieving a lightweight lamp. At the same time, the thickness of 4mm-5mm takes into account the structural strength and light transmission performance of the thick-walled component, avoiding insufficient mechanical stability or increased light propagation loss due to excessive thinness. It can effectively resist vibration and impact during vehicle operation, ensuring structural reliability. This thickness range has good compatibility with mold forming processes, which facilitates the integrated molding of the light-incident surface 141, the total reflection surface 142, and the raised structure, reducing production difficulty and errors, and improving product consistency.
[0045] Furthermore, this application embodiment also provides an electric vehicle, including the headlight optical structure 100 in the above embodiment. The headlight optical structure 100 includes a headlight thick-walled member 110, a lamp holder 120, and a headlight 130. The headlight thick-walled member 110 is a light-transmitting member, and includes a first side and a second side that are positioned opposite each other. A light-incident unit 140 is formed on the first side, and the light-incident unit 140 includes an adjacent light-incident surface 141 and a total reflection surface 142. A light-emitting surface 111 is formed on the second side. The headlight 130 is disposed on the lamp holder 120. The light emitted by the headlight 130 enters the headlight thick-walled member 110 after being refracted by the light-incident surface 141. The height of the headlight 130 is not higher than the upper surface of the headlight thick-walled member 110. The light emitted by the headlight 130 is first refracted through the light-incident surface 141 and enters the thick-walled headlight component 110. The light refracted into the thick-walled component is then totally reflected by the total reflection surface 142 and directed towards the light-emitting surface 111. Finally, it is refracted out of the thick-walled headlight component 110 by the light-emitting surface 111. This light path design, compared to traditional direct and reflective types, requires significantly less space, thereby effectively reducing the thickness of the thick-walled headlight component 110 and achieving lightweighting of the electric vehicle. At the same time, through the reasonable design of the light-incident surface 141 and the total reflection surface 142, the light source can be placed closer to the light-incident surface 141, making the headlight optical structure 100 more compact. While ensuring optical performance, this further improves the space utilization of the electric vehicle.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
