Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically to a structure and control method for a front-projection type vehicle exterior light show. Background Technology

[0002] As living standards rise, consumers' demands for car lighting have gone beyond simply meeting regulatory requirements; they now want cars to offer a cooler and more personalized solution.

[0003] Currently, exterior lighting shows in the automotive market mainly take the form of sequential lighting and flashing of the lights themselves, as well as exterior projection lights. There are many types of exterior projection lights, including headlight projection and carpet light projection, all of which project specific light patterns onto the ground to achieve a particular sense of ceremony or provide specific cues to the driver. However, projection onto the car body itself is currently a blank area in the market; only some modified cars have LED light strips added to their bodies, and there are no examples of projecting aesthetically pleasing light patterns onto the car body. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the first aspect of the present invention provides a structure for a front-projection type vehicle exterior projection light show, including a light-transmitting lamp cover, a decorative frame, a light source assembly, and an opaque lamp housing;

The decorative frame is housed within the cavity formed by the light-transmitting lampshade and the opaque lamp housing. The outer side of the decorative frame faces the light-transmitting lampshade, and the inner side of the decorative frame faces the opaque lamp housing. The light source assembly is installed between the decorative frame and the opaque lamp housing. The light-transmitting lampshade is connected to the opaque lamp housing.

[0006] The decorative frame is provided with a styling grille. The light emitted by the light source component passes through the light-transmitting gap of the styling grille and the light-transmitting lamp cover in sequence, and is projected onto the target position on the vehicle body surface to present a styling pattern.

[0007] Furthermore, the decorative grille is disposed on the side of the decorative frame.

[0008] Furthermore, the light source assembly includes a light source disposed adjacent to the shaped grille, and the number of the light sources is one or more, and the color of the light source is one or more.

[0009] Furthermore, the light source assembly includes a light source and a light guide structure;

[0010] The light source is positioned adjacent to the light-incident surface of the light guide structure, and the light-exiting surface of the light guide structure is positioned adjacent to the shaped grille. The light emitted by the light source enters the light guide structure through the light-incident surface and exits from the light-exiting surface.

[0011] Furthermore, the number of light source components is one or more, the number of shaped grilles is one or more, and the light source components and shaped grilles are arranged in a one-to-one correspondence.

[0012] Furthermore, the shaped grille is made using mold manufacturing, material removal process, or material addition process.

[0013] Furthermore, the shaped grille includes an inner lens and a shaped pattern coating, the shaped pattern coating being an opaque coating whose shape matches the shaped pattern.

[0014] Furthermore, the patterned coating is made by covering a specific location of the inner lens with an opaque coating, or by removing the opaque coating from a specific location of the inner lens.

[0015] Furthermore, the target location on the vehicle body surface includes any one of the front surface of the vehicle body, the rear surface of the vehicle body, and the door surface.

[0016] A second aspect of the present invention provides a control method for a vehicle exterior projection light show, applied to the structure of the front-projection type vehicle exterior projection light show as described above, comprising:

[0017] In response to a detected user input operation, a projection request is sent to the vehicle control center; wherein, the vehicle control center can generate a vehicle body projection command based on the projection request;

[0018] Based on the received vehicle body projection command, control one or more vehicle exteriors with the structure of the front-projecting vehicle exterior light show to light up in a preset mode.

[0019] Furthermore, the user input operation includes pressing the key unlock button, pressing the corresponding button on the center console, and pressing the corresponding button on the mobile APP.

[0020] A third aspect of the present invention provides a computer-readable storage medium storing at least one instruction, at least one program, a code set, or an instruction set, wherein the at least one instruction, the at least one program, the code set, or the instruction set is loaded and executed by a processor to implement the above-described control method for projecting light shows onto vehicle exteriors.

[0021] A fourth aspect of the present invention provides an apparatus comprising a processor and a memory, wherein the memory stores at least one instruction, at least one program, a code set, or an instruction set, wherein the at least one instruction, the at least one program, the code set, or the instruction set is loaded and executed by the processor to implement the above-described control method for a vehicle exterior projection light show.

[0022] The embodiments of the present invention have the following beneficial effects:

[0023] 1. The decorative frame of the present invention is placed in the cavity formed by the light-transmitting lamp cover and the opaque lamp housing, with the outer side of the decorative frame facing the light-transmitting lamp cover and the inner side of the decorative frame facing the opaque lamp housing, which can satisfy the basic functions of vehicle exterior decoration.

[0024] 2. The light source assembly is installed between the decorative frame and the opaque lamp housing. The decorative frame is equipped with a decorative grille. The light emitted by the light source assembly is projected onto the decorative grille from the front. After passing through the light-transmitting gaps of the decorative grille and the light-transmitting lamp housing, it is transformed into a unique optical pattern and projected onto the target position on the vehicle body surface. This expands the vehicle's exterior functions while fulfilling basic functions.
