Description

Lens structure in rear position lamp

Technical Field

The utility model relates to an automotive lighting technical field especially relates to a lens structure in rear position lamp.

Background

The automobile rear position lamp is a lighting device which takes an LED as a light source and is arranged at the rear part of a vehicle, and is used for warning the rear vehicle in the daytime or at night, so that the occurrence frequency of traffic accidents is reduced; present position lamp implementation mode is mostly direct-injection type LED and adds interior lens, and interior lens surface does not have any pattern, and this molding characteristic is relatively more single, and not pleasing to the eye enough, for realizing special molding characteristic, need carry out double-shot moulding or carry out the part partial shipment to interior lens, but this mode can increase mould cost and manufacturing cost, and has increased the complexity of structure, easily produces appearance defects.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a novel plastic bottle which can meet the requirement of more creative shape and improve the brand recognition degree; meanwhile, the manufacturing process of the inner lens can be simplified, and the structure of the inner lens of the rear position lamp can reduce the cost of a mold and manufacture.

In order to achieve the above object, the utility model provides a lens structure in rear position lamp, including interior lens, interior lens's surface attachment has the shading coating be provided with a plurality of printing opacity decorative patterns on the shading coating, the light that the light source sent shines away through the printing opacity decorative pattern with the molding of design.

Further, all or part of the light-transmitting patterns are the same or different in shape and size.

Further, the shape of each light-transmitting pattern is streamline.

Further, the extending direction of each light-transmitting pattern is the same.

Further, the thickness of the light shielding coating ranges from 20 μm to 40 μm.

Further, the thickness of the light-shielding coating is 30 μm.

Further, the shading coating is opaque black paint.

Further, the inner lens is made of PC material.

Further, the inner lens adopts a milky white base material.

Compared with the prior art, the utility model has the following advantage:

the utility model discloses a lens structure in rear position lamp can satisfy the molding more creative, promotes brand recognition; meanwhile, the manufacturing process of the inner lens can be simplified, and the structure of the inner lens of the rear position lamp can reduce the cost of a die and the manufacturing cost; because the thickness of the black paint is very thin, no obvious height difference exists at the joint of the patterns on the surface of the inner lens, and the position lamp is more uniform and more attractive after being lightened.

Detailed Description

The following describes the present invention with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the present embodiment discloses an inner lens structure of a rear position lamp, which includes an inner lens 1 made of a milky white base material, a light-shielding coating 11 attached to an outer surface of the inner lens 1, a plurality of light-transmitting patterns 12 disposed on the light-shielding coating 11, and light emitted from a light source is emitted through the light-transmitting patterns 12 in a designed shape.

In the present embodiment, all or part of the light-transmitting patterns 12 are the same or different in shape and size.

In the present embodiment, each of the transparent patterns 12 has a streamline shape.

In the present embodiment, the extending direction of each light-transmitting pattern 12 is the same.

In the present embodiment, the thickness of the light-shielding coating 11 ranges from 20 μm to 40 μm.

In the present embodiment, the thickness of the light shielding coating 11 is 30 μm.

In this embodiment, the light-shielding coating 11 is opaque black paint.

In the present embodiment, the inner lens 1 is made of PC material.

In this embodiment, a milky white base material is used for the inner lens 1.

Wherein, the shading coating 11 is a non-light-transmitting surface, and the light-transmitting pattern 12 is a light-transmitting surface.

As shown in fig. 1, after the inner lens is injection molded, the outer surface of the inner lens 1 is sprayed with black paint, as shown in fig. 2, after the spraying is completed, the inner lens is placed into a laser engraving device, 3D data of patterns to be engraved are input into the laser engraving device, the conversion power, the scanning speed and the air conditioning temperature of the laser engraving device are set, the laser engraving device is started, a probe engraves the patterns of the inner lens according to set parameters, the engraved black paint is engraved to be milky white on the original substrate, the non-engraved portions are black patterns, after an LED inside the position lamp is lighted, light penetrates through the milky light-transmitting surface, the black portions are absorbed, the two portions are alternately connected to form the modeling characteristic of the position lamp; because the thickness of the black paint coating is very thin, gaps and height differences are almost not formed between the light-transmitting part and the light-proof part, and the position lamp is more uniform after being lightened; the process can be used for realizing line characteristics and familiarization characteristics with particularly narrow and thin modeling. The utility model discloses back position lamp lens sculpture decorative pattern technology implementation scheme, its radium carving equipment parameter sets up to: the conversion power of the laser is about 80%, the scanning speed of the laser probe is about 3000mm/min, and the temperature of the air conditioner is set to be 30-35 ℃.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
