Abstract
Description
[Technical Field]
[0001] This utility model relates to the field of automotive electronic lighting technology, specifically providing an automotive luminous front panel based on dynamic light effects, which can realize vehicle status visualization interaction and safety warning functions. [Background Technology]
[0002] With the continuous advancement of the automotive industry and the deep integration of electronic technology, automotive styling and functional design are increasingly becoming key elements in enhancing product competitiveness and user experience. Traditional automotive front panels, especially the grille area, primarily focus on guiding airflow for engine compartment cooling and providing visual identification of the brand. In terms of lighting and warning, this area typically lacks active light-emitting capabilities; the vehicle's lighting, signal indication, and position warning functions rely almost entirely on independent light source systems such as headlights and fog lights. In the context of increasingly complex traffic environments and rising user demands for vehicle interactivity and personalization, this design is gradually revealing its limitations: limited functionality, limited visual appeal, and a need to enhance overall warning effectiveness in specific environments (such as low-light weather). [Utility Model Content]
[0003] This invention provides a car luminous front panel based on dynamic light effects, which visualizes vehicle status through dynamic light effects, improving interactive experience and driving safety.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A car luminous front panel based on dynamic light effect, comprising a shell, an aluminum substrate, LED lights, LED lamp covers, a light-transmitting panel, clips, and a PCB board. Its features include: three heat dissipation holes on the back of the shell, and clip grooves on the inner sides of the shell; the aluminum substrate has holes for mounting the LED lights and grooves for mounting the LED lamp covers, and 150 LED lights are mounted on the aluminum substrate; the LED lamp covers are welded to the aluminum substrate; the light-transmitting panel is colorless and transparent; the clips and the light-transmitting panel are integrated; the PCB board is located between the aluminum substrate and the shell, and a connector is provided on the PCB board, through which the LED lights are connected to the PCB board via wiring harnesses and connectors.
[0005] The beneficial effects of this invention are as follows: A light-emitting matrix composed of 150 LEDs can present a rich variety of dynamic lighting effects. When the vehicle is in different states such as starting, turning, and braking, changes in the lighting effects can promptly alert pedestrians and other vehicles, improving driving safety. The control unit can automatically adjust the lighting effects according to the vehicle's status signals, realizing information interaction between the vehicle and the outside world, making the car more intelligent during road driving. Multiple LED light source arrays can be independently controlled, allowing consumers to customize personalized lighting effects according to their preferences, satisfying the demand for personalized vehicle appearance. The main panel uses a light-transmitting material and is equipped with an optical diffusion layer, making the light distribution more uniform and improving the visual effect and aesthetics of the front panel.

The housing 1 has three heat dissipation holes on its back to cool the aluminum substrate 2 and PCB board 7, preventing overheating and board burn-out. Clip grooves are provided on both sides of the housing 1 for assembly with the light-transmitting panel 5. The aluminum substrate 2 has holes for mounting the LED lights 3 and grooves for mounting the lamp covers 4, allowing for precise positioning of the LED lights 3 and lamp covers 4. One hundred and fifty LED lights 3 are mounted on the aluminum substrate 2, each equipped with a lamp cover 4. The lamp covers 4 are welded to the aluminum substrate 2. Panel 5 is colorless and transparent, protecting the lamp assembly from damage without reducing light transmission; the clip 6 is an integral part of the light-transmitting panel 5, and the light-transmitting panel 5 is assembled with the housing 1 by cooperating with the clip groove on the housing 1; the PCB board 7 is located between the aluminum substrate 2 and the housing 1, and is used to control the lighting effect. The PCB board 7 is equipped with a connector, and the LED light 3 is connected to the connector on the PCB board 7 through a wiring harness. The PCB board 7 is also connected to the vehicle CAN bus through the connector to receive the vehicle's driving status. The PCB board 7 controls the LED light 3 to achieve different dynamic lighting effects according to different vehicle conditions; the vehicle battery powers the PCB board 7, and the PCB board 7 is connected to the vehicle power supply through a connector.
[0011] When this utility model is in use, the vehicle power supply supplies power to the PCB board through wires. The PCB board determines the vehicle's driving status by receiving information from the vehicle's CAN bus. The PCB board then controls the LED light group to change different lighting effects according to the vehicle's driving status.
[0012] Preferably, in order to improve the dynamic interaction between the vehicle and the person, the PCB board 7 controls the LED lights 3 to achieve different dynamic effects under different vehicle operating conditions.
