Description

A kind of double light guide light leakage fixing rack structures of car light

Technical field

The utility model relates to a kind of double light guide light leakage fixing rack structures of car light, belong to car light light guide designing technique neck Domain.

Background technique

Extensive use with LED technology in car light field, guide structure are more and more frequently applied to Vehicle lamp structure In design.To reach good visual effect and dazzling cruel moulding, it usually will use an even more light guide groups in car light The structure of conjunction.Light source positioned at light guide end can be by light by transmitting inside light guide, by the optics tooth reflection of light guide body Out, reach expected optical effect.When light guide is lighted, due to the guiding property of light guide, entire body is light-emitting surface, is not carried out The zonal ray meeting four of masking is dissipated and is emitted to the inside of lamp body, and that interferes other function lights effect.Light guide body rise it is fixed or The clamping structure of positioning action equally can will be delivered in the light inside light guide and converge because of the guiding property of light guide body, The defect that effect is lighted in the influences such as bright spot is formed on apparent visual.Existing light guide light-shielding structure design is mostly that gear is designed in decorative circle Light muscle or the misconstruction for playing interception, will definitely increase the structural complexity of the components such as decorative circle in this way, set to whole lamp Meter produces limitation, increases whole lamp manufacturing cost, poor universality, while, light leakage phenomena undesirable to the screening effect of light It is difficult to be fully solved.

Utility model content

For disadvantages described above, the utility model provides a kind of double light guide light leakage fixing rack structures of car light.

Technical solution provided by the utility model is:

A kind of double light guide light leakage fixing rack structures of car light, including light guide bracket, left light guide, right light guide, the light guide Bracket includes that curvature is identical as the right light guide of left light guide, for packing tightly the tube-shaped clad structure of left light guide, right light guide, tube-shaped clad knot With the guide bevel being easily installed on structure, light guide bracket is caught in left light by flexible deformation with the strip notch of guide bevel It leads, right light guide；Light guide bracket contains at least one fixed area, for limiting the displacement of left light guide, right light guide relative to whole lamp And rotation；Left light guide, right light guide contain the positioning lordosis for limiting light guide displacement and play in the two sides of light guide bracket respectively Platform, positioning rear boss.

The utility model has the beneficial effects that:

1) without individually increasing stationary positioned structure in light guide body, simplify light guide body shape, improve stationary positioned knot Structure it is universal；

2) the excessive fixed structure bring light loss of light guide body design and bright spot etc. are reduced and lights effect defect, promotes view Feel effect and moulding aesthetic feeling；

3) without increasing the structures such as light-blocking muscle, dislocation zone on the components such as escutcheon, the components such as escutcheon are simplified Structure improves the universal of the components such as escutcheon；

4) manufacturing cost for reducing the components such as escutcheon, reduces the light loss of light source, directly reduction optics cost；

5) assembly manipulation is convenient, and structure is simple, fix stably, can bear the strength impact of high frequency time vibration；

6) size is small, lower cost for material；

7) the selection limitation of good shading effect, shading or fixed position is small, the tube-shaped clad region of bracket and light guide It needs shading position to combine closely, can be very good the masking of control light, avoid that there is a phenomenon where light leakages.

Detailed description of the invention

Fig. 1 is the light guide of the utility model and the structural schematic diagram of light guide bracket installation.

The light guide and the sectional view at light guide bracket tube-shaped clad that Fig. 2 is the utility model.

The light guide and the overall schematic after light guide bracket installation that Fig. 3 is the utility model.

Specific embodiment

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

As shown in Figure 1, Figure 2, the double light guide light leakage fixing rack structures of a kind of car light, including light guide bracket 1, light guide, this implementation Example is two light guides, left light guide 1a and right light guide 2a, and bracket 1 is divided into three parts composition: 1, curvature and left light guide 1a and right light guide 2a is identical, for packing tightly the tube-shaped clad structure 2c of left light guide 1a and right light guide 2a and shading, leads thereon with what is be easily installed To oblique angle 4c.The light guide bracket 1 is caught in left light guide 1a and the right side by flexible deformation with the strip notch 3c of guide bevel 4c Light guide 2a, then the tube-shaped clad structure 2c of light guide bracket 1 packs tightly left light guide 1a and right light guide 2a, limits its displacement, and rise To interception；2, contain at least one fixed area 1c, for limiting the position of left light guide 1a and right light guide 2a relative to whole lamp It moves and rotates；3, each light guide contains positioning front boss 1b, positioning rear boss 2b in the two sides of light guide bracket 1 respectively, is used for Limit rotation and play of the light guide in bracket.Light guide bracket 1 uses soft lighttight plastic material.Light guide bracket and two Elastic compression between light guide.Light guide bracket is fixed on one end of the nearly LED of light guide.The open-mouth ruler of the strip notch 3c of light guide bracket 1 Very little is to be slightly less than the radius for being fixed left light guide 1a, right light guide 2a.
