Vehicle light guide bar mounting structure

Abstract

The invention discloses a vehicle light guide bar mounting structure which is composed of a light guide bar (1), an LED circuit board (2) and a decorative frame, wherein the LED circuit board (2) is fixedly arranged on the light guide bar (1) and fixedly arranged on the decorative frame through the light guide bar (1); the vehicle light guide bar mounting structure is characterized in that a limiting pin (11), a mounting point (12) and a mounting column (13) are arranged on the light guide bar (1), and a leak-proof strip (3) is coated at the incident end; hole sites matched with the limiting pin (11) and the mounting point (12) are formed in the LED circuit board (2); the LED circuit board (2) is limited by the limiting pin (11) and then connected with the light guide bar (1) through the hot-melt mounting point (12); the light guide bar (1) is mounted on the decorative frame through the mounting column (13). According to the vehicle light guide bar mounting structure disclosed by the invention, an assembling process is simplified, the leak-proof strip can be tightly matched with the light guide bar, shading of light rays can be well controlled, and a light leakage phenomenon can be avoided.

Description

technical field [0001] The invention relates to the industry of automobile lamps, in particular to a mounting structure for a light guide strip of an automobile lamp. [0002] technical background [0003] At present, LEDs and light guide strips are more and more common in car light structures; light guide strips are usually plastic solid cylindrical structures with a circular cross section. The light guide strip can transmit the light at the end through the inside of the light guide strip and be reflected by the teeth of the light guide strip. Due to the characteristics of the light guide strip, its entire body is a light-emitting surface, and the unshielded light will shoot into the interior of the lamp body, interfering with the lighting effect of other functions in the lamp. In the past, the processing method was mostly to design a dislocation structure on the bezel to shield unwanted light from certain directions. The disadvantage is that the bezel structure is complic...

AI Technical Summary

Problems solved by technology

The disadvantage is that the bezel structure is complicated, the versatility is poor, and the light shielding effect is not ideal, and light leakage will inevitably occur

[0004] When assembling the light guide strip bracket and the reflector on the existing car lamp, due to the requirements of assembly reliability, it is generally necessary to use multiple fasteners, many parts are used, the cost is high, the process is more complicated, and the stability is also limited.
