Embodiment Construction

[0015] In order to enable those skilled in the art to fully understand the technical solutions and beneficial effects of the present invention, a further detailed description will be given below in conjunction with specific embodiments and accompanying drawings.

[0016] Such as Figure 1-2 A novel light guide fixing structure shown includes a lamp housing 1 , a radiator 2 , a PCB board 3 , a light guide bracket 4 , a light guide support 5 , a light guide 6 and several screws 7 . The lamp housing 1 is used as the assembly body, and other components are directly or indirectly fixed on the lamp housing. Specifically, the PCB board 3 and the light guide bracket 4 are fixed to the heat sink 2 by two 3X8 screws to form a subassembly, the subassembly is fixed to the lamp housing 1 by three 4X14 screws, and the light guide support 5 is fixed by three 4X14 screws. Screws are also fixed to the lamp housing 1 . The light guide with a slender shape is fixed as follows: First, the two e...

Abstract

The invention provides a novel automobile light guide fixing structure. The structure comprises a lamp housing, a heat sink, a PCB board, a light guide bracket, a light guide support and a light guide, wherein the PCB board and the light guide bracket are fixed on the heat sink to form a sub-assembly body, the sub-assembly body and the light guide support are fixed on the lamp housing, the two ends of the light guide are respectively connected with the light guide support and the light guide bracket by buckles, and a continuous elongated rib in the middle of the light guide is embedded in a groove supported by the light guide to further fix the light guide. The structure can not only meet the optical requirements of regulations, but also produce a uniform lighting effect, avoid the occurrence of bright spots in the middle of the light guide, and solve the problem of how to install the light guide with minimum space in the case where a modeling trend gets smaller.

Description

technical field [0001] The invention relates to the technical field of automobile lighting, in particular to a novel automobile light guide fixing structure. Background technique [0002] At present, most of the car light guide fixing methods on the market adopt buckles arranged at a certain distance along the outline of the light guide for clamping and fixing. Due to the existence of the buckle in the middle, this common fixing method often has disadvantages such as uneven light emission and being limited by the space position. Therefore, the present invention provides a new fixing structure for automobile light guides. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the existing automobile light guide fixing methods, and provide a new automobile light guide fixing structure. It meets the requirement of stable and reliable assembly and can realize uniform lighting effect. [0004] In order to ach...
