Automobile front light-emitting sign

Abstract

The invention discloses an automobile front light-emitting sign. The automobile front light-emitting sign comprises a lampshade insert, a front lampshade, a shading piece, a light guide plate, an LEDmodule and a lamp shell. The lampshade insert and the front lampshade are fixed through laser welding; the front lampshade, the light guide plate and the lamp shell are sequentially sealed and fixed.The shading piece is clamped and fixed with the light guide plate; the LED module is fixed on the lamp shell; the front lampshade is made of PMMA materials through highlight injection molding, and light curing is not needed. The front lampshade, the lamp shell and the light guide plate are fixed and sealed through a vibration friction welding process. The inner surface of the front lampshade achieves the semitransparent and semi-reflective electroplating effect through controllable aluminum plating. The shading piece, the light guide plate and the lamp shell are made of PC materials through injection molding, and uniform light emitting is guaranteed through the shape follow-up design.

Description

technical field [0001] The invention belongs to the technical field of luminous signs on the exterior of automobiles, and in particular relates to a luminous sign on the front of an automobile. [0002] technical background [0003] Most of the traditional car logos use chrome plating and screen printing to achieve a metallic texture. It only acts as a sign when driving in the daytime, and it is invisible when the vehicle is driving at night, which limits the application effect of the sign. [0004] With the increasing number of automotive products and the increasingly fierce competition in the automotive industry, traditional decorative parts can no longer meet the aesthetic needs of users, and luminous signs have emerged as the times require. However, there are still the following problems in the development of luminous signs: first: not only to ensure the original color effect of the sign, but also to enhance the recognition of the vehicle at night; second: for signs with...

It only acts as a sign when driving in the daytime, and it is invisible when the vehicle is driving at night, which limits the application effect of the sign

[0004] With the increasing number of automotive products and the increasingly fierce competition in the automotive industry, traditional decorative parts can no longer meet the aesthetic needs of users, and luminous signs have emerged as the times require

However, there are still the following problems in the development of luminous signs: first: not only to ensure the original color effect of the sign, but also to enhance the recognition of the vehicle at night; second: for signs with three-dimensional shapes, that is, the lampshade has a three-dimensional shape effect (non-planar), the traditional light-emitting sign lampshade is mostly made of PC material, and the surface of the PC lampshade is light-cured to prevent the lampshade from yellowing during use. The PC lampshade has the problem of light-cured varnish, which affects the appearance of the parts; third: the layout of the front sign Due to space constraints, it is difficult to arrange light-emitting elements

The disadvantages are: only the traditional luminous sign, LED light, light guide plate astigmatism, not involved in the inner surface treatment of the lampshade, did not solve the problem of PC lampshade photocuring silt paint, did not achieve good sealing

Disadvantages are: the signage also achieves the effect of light transmission by controlling the thickness of the electroplated coating on the outer surface, which does not involve the inner surface treatment of the lampshade, and does not solve the problem of PC lampshade light-cured silt paint
