Description

Technical Field

[0001] This application relates to the field of lighting technology, and in particular to an autonomous driving assistance light for new energy vehicles. Background Technology

[0002] With the rapid development of the times, the economy, technology, and other fields have all achieved rapid progress. People's living standards are rising, the demand for cars is constantly increasing, and car ownership continues to grow. Today, cars are no longer high-end consumer goods, but have become practical tools for every household.

[0003] Technological advancements have spawned numerous innovative products, including autonomous driving technology in the new energy vehicle sector. However, behind this development lies the environmental pollution caused by vehicle exhaust emissions, prompting serious reflection. Achieving coordinated development between the environment, economy, and technology has become a shared goal for people in the new century. Besides environmental pollution, traffic accidents also bring suffering. The automotive industry is not yet perfect, and continuous innovation is constantly improving the functions and performance of new energy vehicles—from highly efficient and energy-saving electric commercial vehicles to intelligent autonomous driving technology, from innovative design concepts to sustainable development solutions.

[0004] Autonomous driving assistance lights are special lighting systems designed for autonomous vehicles. Their core purpose is to enhance the interaction between the vehicle and the outside world (including other road users, infrastructure, etc.) through light signals, thereby improving safety, communication efficiency and traffic flow in autonomous driving scenarios.

[0005] The purposes of setting up autonomous driving assistance lights include: (1) Replaces the human driver's body language communication and transmits information that the vehicle is in autonomous driving mode to other road users (pedestrians, vehicles) in real time; (2) Clarify vehicle status and reduce misunderstandings. Autonomous vehicles may be in different modes (such as "autonomous driving", "human intervention", "faulty stop"). The auxiliary lights can clearly inform the outside world through the combination of lights to avoid other road users causing accidents due to misjudging the vehicle status; (3) Integrating with intelligent infrastructure to optimize traffic efficiency. In vehicle-road cooperative scenarios, auxiliary lights can communicate with intelligent traffic lights, road sensors and other devices to provide real-time information feedback through changes in lighting.

[0006] The limitation of existing technologies is that conventional lighting systems and driver body language cannot meet the needs of vehicles to communicate fully and efficiently with the outside world in autonomous driving scenarios. The light from conventional lighting systems is not clear and accurate enough to accurately convey the information that the vehicle is in autonomous driving mode to other road users in real time, which can easily lead to other road users misjudging the vehicle's status and causing traffic accidents. Summary of the Invention

[0007] To address the aforementioned issues, this application provides an autonomous driving assistance light for new energy vehicles.

[0008] An autonomous driving assistance light for a new energy vehicle includes a lamp housing, a base, and an optical module. The lamp housing and the base are detachably connected by screws and enclose each other to form a sealed cavity. The optical module is fixed in the sealed cavity by a step-limiting fit between the lamp housing and the base. The optical module includes a heat sink, a wall thickness component, and a lamp board, and the lamp board is electrically connected to the control board via a waterproof wiring harness. An LED light group is provided on the side of the light panel facing the wall thickness member. The LED light group consists of several blue LED beads and green LED beads arranged at intervals. The light source of the LED light group is emitted outward after being processed by the wall thickness member.

[0009] By adopting the above technical solutions, the lamp housing and base are detachably connected by screws for easy installation and maintenance. The enclosed sealed cavity can prevent dust, moisture and other substances from entering and affecting the internal components. The optical module is fixed more stably by step limit cooperation. The lamp board is electrically connected to the control board through waterproof wiring harness to ensure circuit safety and reliability. The LED lamp group composed of blue and green LED beads emits light after the wall thickness is processed, which can realize functions such as replacing human driver body language communication, clarifying vehicle status, and linking with intelligent infrastructure, thereby improving safety, communication efficiency and traffic flow in autonomous driving scenarios.

[0010] Preferably, the wall thickness component includes a reflector and a diffuser. The reflector receives light emitted from the LED group on the side facing the lamp panel. One end of the diffuser is connected to the reflector, and the other end is inserted into the lamp opening formed by the lamp housing and the base through an interference fit. The diffuser directs the light reflected by the reflector outward through the lamp opening.

[0011] By adopting the above technical solution, the reflector receives the light emitted by the LED light group, the diffuser directs the light outward through the lamp opening, and the wall thickness makes the light source more uniform and softer while ensuring clarity, thus better realizing the interaction between the vehicle and the outside world through light signals.

[0012] Preferably, the reflector includes multiple integrally formed light-receiving parts and reflective parts. The reflector has a light channel inside that connects the light-receiving parts and the reflective parts. The light channel is connected to the outside through the end of the light-receiving part away from the reflective part. The input end of each light channel is directly opposite to one of the LED beads in the LED light group.

[0013] By adopting the above technical solution, the light channel input end is set directly opposite to the LED lamp beads, which allows the light emitted by each lamp bead to accurately enter the light channel, achieving efficient collection and guidance of light, further ensuring that the light propagates along the predetermined path, and improving the accuracy and effectiveness of light signal transmission.

[0014] Preferably, an angle is provided between the reflective part and the light-receiving part, so that the light channel forms a first reflective surface and a second reflective surface in the reflective part. The first reflective surface is located above the second reflective surface. The first reflective surface reflects the light transmitted by the light-receiving part to the second reflective surface, and after being reflected by the second reflective surface, it is transmitted towards the diffuser.

[0015] By adopting the above technical solution, an angle is set between the light-receiving part and the reflective part to form the first and second reflective surfaces. The light transmitted by the light-receiving part is reflected sequentially by the first reflective surface to the second reflective surface, and then transmitted towards the diffuser. This light reflection path can better guide the light to the diffuser, which is beneficial to the final light emission rate.

[0016] Preferably, a focusing crystal is fixed in the light-receiving part by a transparent adhesive. The side of the focusing crystal facing the lamp panel is set as a convex arc surface, and the convex arc surface is set opposite to the light-emitting center of the corresponding lamp bead. The side of the focusing crystal facing the reflective part is set as a plane, and the plane is perpendicular to the axis of the light channel.

[0017] By adopting the above technical solution, a light-concentrating crystal is fixed in the light-receiving part with a transparent adhesive. Its convex arc surface is opposite to the light-emitting center of the lamp bead, and its plane is perpendicular to the light channel axis. This can concentrate the light emitted by the lamp bead, improve the light utilization efficiency, and enhance the light intensity and directionality.

[0018] Preferably, the diffuser is a microcrystalline glass with a frosted layer on its surface, the frosted layer being disposed towards the reflector.

[0019] By adopting the above technical solution, the diffuser uses microcrystalline glass with a frosted layer on the surface facing the reflector, which can better diffuse the light, making the emitted light softer and more uniform, further enhancing the interaction between the vehicle and the outside world, and making the light source less dazzling.

[0020] Preferably, the heat sink includes a heat-conducting plate, which is fixedly installed on the side of the lamp board away from the LED lamp assembly by screws, and thermal grease is applied between the heat-conducting plate and the lamp board; the heat sink also includes multiple heat sinks fixedly disposed on the side of the heat-conducting plate away from the lamp board, the multiple heat sinks are arranged in parallel and spaced apart, and heat dissipation air channels are formed between adjacent heat sinks.

[0021] By adopting the above technical solution, the heat-conducting plate and the lamp plate are fixed with screws and coated with thermal grease, which can efficiently conduct the heat generated by the lamp plate; multiple parallel and spaced heat sinks form a heat dissipation channel, which can effectively expand the heat dissipation area, improve heat dissipation efficiency, and ensure the stable operation of the autonomous driving assistance lights.

[0022] Preferably, a long strip-shaped support plate is provided circumferentially inside the lamp housing, the bottom of the heat sink is fixed to the support plate by bolts, the top of the heat sink abuts against the top wall of the lamp housing, and the heat sink divides the inside of the lamp housing into an independent heat dissipation cavity, which is located on the side of the heat sink away from the lamp plate.

[0023] By adopting the above technical solution, a long strip support plate is set along the circumference inside the lamp housing. The bottom of the heat sink is fixed to the support plate with bolts and the top of the heat sink abuts against the top wall of the lamp housing, which can make the heat sink installed stably. At the same time, the heat sink separates the inside of the lamp housing into an independent heat dissipation cavity, which can centrally manage and dissipate the heat generated by the lamp board and other components, thereby improving heat dissipation efficiency.

[0024] Preferably, the top of the lamp housing has a plurality of heat dissipation holes that communicate with the heat dissipation cavity. The heat dissipation holes are evenly distributed along the length of the top of the lamp housing, and the axis of each heat dissipation hole is inclined at 30°-45° to the vertical direction, with the opening facing the upper outer side of the lamp housing.

[0025] By adopting the above technical solution, heat dissipation holes that communicate with the heat dissipation cavity are opened on the top of the lamp housing. The heat dissipation holes are evenly distributed, inclined along the axis, and open outward and upward. This can effectively promote the discharge of hot air from the heat dissipation cavity, while preventing rainwater and other liquids from directly entering the heat dissipation cavity, thus ensuring the heat dissipation effect and the stability of the working environment of the optical module.

[0026] Preferably, a filter screen is fixed inside the heat dissipation cavity at the position corresponding to the heat dissipation hole. The filter screen is a metal dustproof screen, and its edge is fixed to the inner wall of the heat dissipation cavity by elastic claws.

[0027] By adopting the above technical solution, a metal dustproof mesh is fixed as a filter in the heat dissipation cavity at the position corresponding to the heat dissipation hole. Its edge is fixed to the inner wall by elastic claws, which can effectively block dust from entering the heat dissipation cavity, prevent dust from affecting the heat dissipation effect and damaging the internal components. At the same time, the elastic claws facilitate the installation and removal of the filter, making it convenient for subsequent cleaning and maintenance.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. By projecting light outward through LED light clusters, the vehicle can replace the body language communication of a human driver and convey the information that the vehicle is in autonomous driving mode to other road users in real time. 2. Different combinations of lights can clearly indicate the vehicle's status, reduce misunderstandings, and prevent other road users from causing accidents due to misjudging the vehicle's status; 3. The auxiliary lights can communicate with intelligent traffic lights, road sensors and other equipment, and provide real-time information through light changes, so as to work with intelligent infrastructure to optimize traffic efficiency.

Detailed Implementation

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] In the description of the invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the invention.

[0033] This application discloses an autonomous driving assistance light for a new energy vehicle, referring to... Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 9 This auxiliary light is installed inside the vehicle's driver's compartment, close to the rear windshield, and fixed to the tailgate via a base 20. Specifically, it includes a lamp housing 10, a base 20, and an optical module. The lamp housing 10 and the base 20 are detachably connected by screws and form a sealed cavity inside. The optical module is secured within the sealed cavity by the stepped engagement of the lamp housing 10 and the base 20, preventing dust, moisture, etc., from entering and affecting the performance of the optical module, ensuring the reliability and stability of the auxiliary light, making the optical module firmly installed, not easy to shake, and ensuring its normal operation.

[0034] Reference Figure 1 and Figure 2 The optical module includes a heat sink 30, a wall thickness member 50, and a lamp board 40. The lamp board 40 is electrically connected to the control board 60 via a waterproof wiring harness 61. An LED light group 401 is provided on the side of the lamp board 40 facing the wall thickness member 50. The LED light group 401 consists of several blue and green LED beads arranged at intervals. The light source of the LED light group 401 is emitted outward after being processed by the wall thickness member 50. The combination of blue and green light can emit light of a specific color and intensity, making it easier for other road users to identify. In this embodiment, LED beads with a blue light wavelength range of 450-495nm are used. These LEDs have high energy and strong visual contrast, making it easier to overcome background light interference in bright environments (such as during the day or under city lights) and attract human visual attention. In nighttime environments, the human eye has a higher sensitivity to blue light in dark vision (consistent with the Purkinje effect). The blue light auxiliary lamp can allow pedestrians to detect the presence of vehicles from 50 meters away without being glaring. Furthermore, while blue light scatters more strongly in the air than red light, its high brightness allows for greater visibility over clear weather. Blue-green LEDs consume less energy; blue LEDs have a photoelectric conversion efficiency of 30%-35%, and red LEDs have a photoelectric conversion efficiency of 25%-30%, which is more energy-efficient than the 20%-25% photoelectric conversion efficiency of traditional red LEDs. This makes them suitable for the low-power requirements of autonomous vehicles, especially electric vehicles that need optimized range.

[0035] Reference Figure 2 and Figure 10The wall thickness component 50 adjusts and processes the light, making it more uniform and softer while maintaining concentration, thus enhancing the visual effect. The wall thickness component 50 includes a reflector 501 and a diffuser 508. The diffuser 508 is made of microcrystalline glass with a frosted layer on its surface, facing the reflector 501. The frosted layer allows for diffuse reflection of the light, making it softer. The reflector 501 receives the light emitted from the LED light group 401 on the side facing the lamp panel 40. One end of the diffuser 508 is connected to the reflector 501, and the other end is inserted into the lamp opening formed by the lamp housing 10 and the base 20 via an interference fit. The diffuser 508 guides the light reflected by the reflector 501 outward through the lamp opening. The LED light group 401 emits blue or green light, or a combination of blue and green light, which is uniformly emitted after being processed by the wall thickness component 50, clearly conveying information such as the vehicle's autonomous driving status to the outside world.

[0036] Reference Figure 2 The reflector 501 includes multiple integrally formed light-receiving parts 502 and reflective parts 503. A light channel 504 is formed inside the reflector 501, connecting the light-receiving parts 502 and the reflective parts 503. The light channel 504 communicates with the outside through one end of the light-receiving part 502 away from the reflective part 503. The input end of each light channel 504 is directly opposite to one of the LED beads in the LED light group 401. An angle is formed between the reflective part 503 and the light-receiving part 502, so that the light channel 504 forms a first reflective surface 506 and a second reflective surface 507 within the reflective part 503. The first reflective surface 506 is located above the second reflective surface 507, reflecting the light transmitted from the light-receiving part 502 to the second reflective surface 507. After reflection by the second reflective surface 507, the light is transmitted towards the diffuser 508. A focusing crystal 505 is fixed inside the light-receiving part 502 with transparent adhesive. The side of the focusing crystal 505 facing the lamp panel 40 is set with a convex arc surface, and this convex arc surface is set opposite to the light-emitting center of the corresponding lamp bead. The side of the focusing crystal 505 facing the reflector 503 is set with a flat surface, which is perpendicular to the axis of the light channel 504. The light emitted by the lamp beads of the LED lamp group 401 passes through the convex arc surface of the focusing crystal 505, causing the scattering optical fiber of the LED lamp group 401 to refract into parallel light rays, and guide the light to the first reflective surface 506. The reflector 503 is made of metal material, and the surfaces of the first reflective surface 506 and the second reflective surface 507 are smooth to improve the reflection effect. Both the first reflective surface 506 and the second reflective surface 507 are set as flat planes. After two reflections, the light is changed in path and shines on the diffuser 508 as a straight light ray. The light processed by the diffuser 508 is emitted more softly and evenly.

[0037] Reference Figure 2 and Figure 5The heat sink 30 includes a heat-conducting plate 301 made of copper. The heat-conducting plate 301 is fixed to the side of the lamp panel 40 away from the LED lamp assembly 401 by screws. Thermal grease is applied between the heat-conducting plate 301 and the lamp panel 40. The thermal grease has good thermal conductivity and can fill the tiny gaps between the heat-conducting plate 301 and the lamp panel 40, improving heat conduction efficiency and allowing the heat generated by the lamp panel 40 to be quickly transferred to the heat-conducting plate 301. The heat sink 30 also includes multiple heat sinks 302 made of aluminum, fixedly disposed on the side of the heat-conducting plate 301 away from the lamp panel 40. The multiple heat sinks 302 are arranged in parallel and spaced apart, forming a heat dissipation channel 303 between adjacent heat sinks 302. Air can flow in the heat dissipation channel 303, carrying away heat and thus reducing the temperature of the lamp panel 40 and the entire optical module.

[0038] Reference Figure 1 , Figure 3 , Figure 4 and Figure 11 The lamp housing 10 has a long, circumferentially protruding support plate 202 inside. The bottom of the heat sink 30 is fixed to the support plate 202 with bolts, and the top of the heat sink 30 abuts against the top wall of the lamp housing 10. The heat sink 30 divides the interior of the lamp housing 10 into an independent heat dissipation cavity 103, which is located on the side of the heat sink 30 away from the lamp panel 40. The top of the lamp housing 10 has several heat dissipation holes 101 that communicate with the heat dissipation cavity 103. The heat dissipation holes 101 are evenly distributed along the length of the top of the lamp housing 10. The axis of each heat dissipation hole 101 is inclined at 30°-45° to the vertical direction, and the opening faces the upper outer side of the lamp housing 10, which can increase the heat dissipation area. A filter screen 102 is fixed inside the heat dissipation cavity 103 at the position corresponding to the heat dissipation holes 101. The filter screen 102 is a metal dustproof mesh, and its edge is fixed to the inner wall of the heat dissipation cavity 103 by elastic claws 105. The independently set heat dissipation cavity 103 exchanges airflow with the outside through the heat dissipation hole 101. The heat dissipation cavity 103 is not connected to the cavity of the optical module, which can prevent moisture and dust from entering and improve the sealing and dustproof performance of the lamp. The filter screen 102 can isolate a certain amount of dust.

[0039] The implementation principle of this application embodiment is as follows: The auxiliary light of this application is installed inside the driver's cab, close to the rear windshield, and the optical module is fixed by the sealed cavity formed by the lamp housing 10 and the base 20, which can prevent dust and water vapor.

[0040] In the optical module, the blue-green LED lights on the light panel 40 emit light, which is refracted into parallel light by the focusing crystal 505, and then transmitted to the diffuser 508 through the two reflective surfaces of the reflector 501, so that the light is emitted evenly and softly, conveying autonomous driving status information. Blue-green light is easily identifiable and energy-saving, which is suitable for the needs of autonomous driving.

[0041] For heat dissipation, heat from the lamp board 40 is transferred to the aluminum heat sink 302 via a copper heat-conducting plate 301 coated with thermal grease, forming an airflow channel. The heat sink 30 has an independent heat dissipation chamber 103, which is ventilated through inclined heat dissipation holes 101 and protected against dust by a filter screen 102. The heat dissipation chamber 103 is isolated from the optical cavity, balancing heat dissipation and sealing to ensure stable operation of the auxiliary lamp.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
