Description

A kind of car light light guide is fixed and assembling structure

Technical field

The utility model belongs to automobile lamp light guide mounting technique field, and in particular to a kind of light for automobile lamp Lead fixed knot.

Background technique

At present in automobile lamp design, the uniformity requirement that client lights effect for car light is more stringent, moulding Be it is more next long and narrow, optical requirement is also very stringent；This just needs the tolerance between strict control LED and light guide, however LED module It is installed in above lamp housing, in order to guarantee precision, very little that the position gap between light guide and lamp housing can be stayed；Due to the limit of moulding System, light guide sometimes can only be on mask assemblies；After light guide is attached on mask assembly in this way, between mask assembly and lamp housing assembly Be assembled into a more scabrous problem.Light guide fixed form common at present is that light guide is fixed on to mask assembly On, if this mode meets the precise positioning of light guide and lamp housing, it is difficult to guarantee mask assembly and lamp housing assembly auto-stitching Gap needed for assembly, to affect production efficiency, increases cost because fit-up gap is greater than position gap.Cause This, it is necessary to structure optimization is carried out to its fixed form, to overcome these defects.

Utility model content

The technical issues of the utility model is in order to solve automobile lamp light guide fixing assembling provides a kind of car light light guide Fixed and assembling structure.

Technical solution provided by the utility model is:

A kind of car light light guide is fixed and assembling structure, including deck, deck bracket, light guide, lamp housing, LED module；The light It leads and is located in lamp housing opening, deck bracket is packed into lamp housing opening, and light guide head passes through deck carrier openings, and deck is covered in light guide On head, light guide head is fixed on above deck bracket by rotating, LED module is assembled on lamp housing, is provided on deck For fixing the deck areole on light guide head, and limitation light guide axial freedom deck limit rib.

The deck is circle.

The LED module is fixed by screws on lamp housing.

Compared with prior art, the utility model has the beneficial effects that

1. the utility model structure is simple, in mask assembly and lamp housing gluing bonding processes, light guide and lamp housing assembly it Between have enough fit-up gaps, smoothly completed so that auto-stitching be effectively ensured.

2. the utility model is by using the fixed light guide head of deck, and easy to operate need to rotate and tighten, effectively Solve light guide occur axial float, ensure that the tolerance with LED module well.

3. the utility model will be disassembled out with the place of light guide head fits, it is put into and assembles below, and and LED module It directly positions, not only ensure that light guide head and the gap of LED, but also solve the problems, such as automation pressing production.

Detailed description of the invention

Fig. 1 is the utility model configuration schematic diagram.

Fig. 2 is the mask assembly of the utility model and the installation diagram of lamp housing assembly.

Fig. 3 is the A direction view of Fig. 2 of the utility model.

Fig. 4 is the structural schematic diagram of the deck of the utility model.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

Such as Fig. 1, a kind of car light light guide is fixed and assembling structure, including light guide 1, lamp housing 2, deck bracket 3, deck 4 and LED module 5.

In this embodiment, the light guide 1 is assemblied on mask assembly 6, and mask assembly, will by automation process for pressing Itself and lamp housing assembly 7 press, shown in attached drawing 2.During mask assembly 6 and lamp housing 7 auto-stitching of assembly, light guide 1 and lamp housing There are enough fit-up gap d1 and d2 between assembly 7, as shown in Figure 3.

Referring to Fig. 1, after mask assembly and lamp housing assembly auto-stitching, light guide 1 is located in lamp housing opening 9, then again will Deck bracket 3 is packed into lamp housing opening 9, so that light guide head 8 is passed through deck carrier openings 10, then by 4 sets of deck on light guide head 8 On, light guide head 8 is screwed in by 11 the inside of deck areole by rotation, deck limit rib 12 snaps on deck bracket 3, finally will LED module 5 is assembled on lamp housing 2, while being compressed deck bracket 3 by LED module 5, thus limit light guide head and LED it Between distance.The deck 3 is circle, and for limiting 5 freedom degrees on light guide head 8, deck areole 11 is used to fix light Top guide portion 8, deck limit rib 12 limit the axial freedom of light guide 1.Deck bracket 3 be it is directly fixed with deck 2, without and Lamp housing is fixed, and can reduce the size chain length axial in assembly in this way, to improve the precision between light guide head and LED. Deck bracket 3 and LED module 5 directly position, and deck bracket 3 is pressed between lamp housing and LED module by sandwich mode.

The utility model structure is simple, makes Automated assembly simple possible by disassembling deck bracket.The utility model Using the fixed light guide of deck, effective solution is under illuminating state, the problems such as the speck of generation, light leakage；For longer light It leads, can effectively play correcting, while also functioning to a preferable fixed function.
