Description

Multi-vehicle-type common luminous vehicle logo and production method thereof

Technical Field

The invention belongs to the technical field of luminous vehicle logos, and particularly relates to a luminous vehicle logo shared by multiple vehicle types and a production method thereof.

Background

With the trend of the appearance of the automobile, the appearance of the automobile is more and more personalized, and the automobile appearance decorating electroplated part which is often used as the automobile decorating part cannot meet the requirement of people on the appearance decorating of the automobile. Thus, while the functions of headlights of automobiles are more intelligent and the styling is more dazzling, the adoption of through lights in the grilles symbolizing the "front face" of the vehicle has been gradually started by the car factories. The car logo located in the middle of the grille to symbolize the image of the car factory gradually starts to start the car logo with the light-emitting function, and forms a mutual storage lamp system together with the through lamp on the grille and the head lamps located at two sides of the vehicle, which is generally called as a 'Y' -shaped lamp system by the industry, and plays roles of front-end illumination and position indication in the driving process of the vehicle.

Meanwhile, some car logos with the functions of lighting, lighting and lighting, running light and breathing light are used as atmosphere lights and are arranged in the middle of a grille of a car head, the car logos are used as common decorative car logos in daytime and are used as auxiliary functions when a vehicle stops at night, and various lighting effects can be presented according to habits of car owners.

In the past few years, due to the fact that few application examples exist, regulations of domestic and foreign vehicle lamps are different, and various large vehicle factories in the Chinese market are in a watching state, the application of the luminous vehicle logo only stays in a rear-loading market at the moment, and due to high cost, the vehicle logo can be rarely seen on vehicles running on the street.

With the rapid advancement of electric driving of vehicles in China, more and more technical departments of domestic car factories have recently begun to develop car logos with light-emitting functions. Especially, some electric vehicle platforms of the traditional vehicle factories directly list the luminous vehicle labels as full-system standard parts, platform parts and even standard parts for management and application. In order to meet the revolution of vehicle logos, many car light factories and professional part suppliers have conducted advanced research to better reserve the market share for supplying such parts.

In the present day of the millimeter wave label technology, the requirement of each large host factory for the decoration pattern of the label itself is higher and higher. Therefore, the label with various effects and colors can be produced. The label comprises a pattern combined by black, blue and electroplated high-brightness metal effect colors which are widely applied to electric vehicles. In order to achieve this appearance effect, many process steps are required. The machining links often need a plurality of tools and auxiliary fixtures; this development label brings about a defective rate and a high development cost.
