An aliphatic transparent grade material with high wear resistance, high impact resilience, high elasticity, high strength, and high weather resistance is used in the skin layer 2. Materials having good adhesion property each other, thermo plasticity, and compatibility are used in the skin layer 2 and the lens 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for a vehicle in which a chamber is defined by a lens and a housing of a resin molded product, and more particularly, to a method of reliably preventing a lens from being damaged, damaged, attacked by a chemical product, and the like. Environmentally favorable for vehicles that can protect, and can reliably prevent the scattering of lens fragments when the lens is broken, and also has good adhesion to the lens, high productivity, and low equipment cost It concerns the device. Here, the vehicle device refers to a vehicle lamp, a vehicle accessory, and the like. The above-described vehicle lamp includes, for example, a head lamp, a fog lamp, a rear combination lamp, a front combination lamp, a turn signal lamp, a clearance lamp, a cornering lamp, and the like. Further, the above-described vehicle accessory refers to, for example, a rear finisher, a garnish, or the like.

[0002]

2. Description of the Related Art In a vehicle apparatus of this type, a chamber is generally defined by a lens and a housing of a resin molded product. A hard coat treatment (painting) is applied to the surface of the lens (mainly, the outer surface opposite to the inner surface facing the chamber) to protect the lens.

[0003]

However, in the above-described conventional vehicle apparatus, since the surface of the lens is subjected to a hard coat treatment, the lens may be damaged, damaged, attacked by chemical products, or the like. It is easily affected, and there is a risk that fragments of the lens may be scattered when the lens is damaged, and further, there is a problem in adhesion to the lens. Moreover,
Since a painting process is required, there are problems such as a problem in productivity, a high equipment cost, and environmental unfavorability due to the use of an organic solvent.

SUMMARY OF THE INVENTION It is an object of the present invention to reliably protect a lens from being scratched or damaged, to attack chemical products, etc., to prevent the scattering of lens fragments when the lens is damaged, and to further prevent the lens from being damaged. An object of the present invention is to provide an environmentally favorable vehicle device that has good adhesion, high productivity, can suppress equipment cost, and is environmentally friendly.

[0005]

In order to achieve the above-mentioned object, the present invention is characterized in that a TPU skin layer is formed on the surface of a lens by two-color molding. As a result, the vehicle device of the present invention damages the lens due to the wear resistance, rebound resilience, elasticity and strength of the TPU skin layer,
Can be reliably protected from damage, attack of chemical supplies, etc.
Further, when the lens is damaged, the scattering of the lens fragments can be reliably prevented. Furthermore, by two-color molding with the lens,
It has good adhesion to the lens, high productivity, can reduce equipment cost, and is environmentally preferable without using an organic solvent.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a vehicle device according to an embodiment of the present invention. In this example, a headlamp (an automotive headlamp) will be described as a vehicle device. In FIG. 1, reference numeral 1 denotes a headlamp lens. The lens 1 is a resin molded lens. As the resin of the lens 1, for example, PC resin, PMM
A resin, COP resin (cycloolefin polymer resin), transparent PA resin and the like.

A skin layer 2 made of TPU (thermoplastic urethane or thermoplastic polyurethane resin) is provided on the surface of the lens 1 (mainly, the outer surface opposite to the inner surface facing the lamp chamber 4 described later). It is formed by color molding. The skin layer 2 of this TPU has abrasion resistance, rebound resilience,
An aliphatic transparent grade material having excellent elasticity, strength, (weather resistance) and the like is used.
Also, the skin layer 2 of this TPU and the above-mentioned lens 1
Materials that have good adhesion to each other, are both thermoplastic, and are compatible are used.

In FIG. 1, reference numeral 3 denotes a lamp housing of a headlamp. This lamp housing 3 is, for example,
It is made of a resin containing PP talc. Inner surface of the lamp housing 3 (surface facing the room 4 described later)
Is formed with a reflection surface 30. Although the above-described lamp housing 3 has an integral structure with the reflection surface 30, the lamp housing and the reflector having the reflection surface may be formed separately.

A lamp chamber 4 is defined by the above-mentioned lens 1 (the surface of which is formed by doping a skin layer 2 of TPU) and the above-mentioned lamp housing 3. Also,
The light source bulb 5 is detachably attached to the lamp housing 3 described above.
Are arranged at predetermined positions in the lamp room 4. When the light source bulb 5 is turned on, light from the light source bulb 5 is reflected by the reflection surface 30, and the reflected light is formed on the lens 1 (TPU skin layer 2 is formed on the surface by doping). And is radiated to the outside in a predetermined light distribution pattern.

The vehicle device according to the present invention in this embodiment has the above-described structure, that is, the TP
Since the U skin layer 2 is formed by two-color molding, the skin layer 2 is superior in abrasion resistance, rebound resilience, elasticity, and strength as compared with the hard coat treatment (painting). The lens 1 can be reliably protected from being scratched, broken, attacked by chemical supplies, and the like. In particular, it is resistant to damage of a hitting system such as chipping and has sufficient resistance to damage by sand. When the lens 1 is damaged,
Can be reliably prevented from being scattered. Further, the two-color molding of the lens 1 and the TPU skin layer 2 provides good adhesion between the lens 1 and the TPU skin layer 2.
In addition, since the TPU skin layer 2 can be formed on the surface of the lens 1 by two-color molding in the molding step, the painting step is unnecessary, and accordingly, the productivity is good, the equipment cost can be suppressed, and the organic solvent can be reduced. Environmentally friendly without use.

Particularly, in this embodiment, the lens 1
And the TPU skin layer 2 are both made of a thermoplastic and compatible resin.
The lens 1 having the PU skin layer 2 can be used, for example, for reproduction into a lamp housing or the like.

In the above-described embodiment, a description has been given of an example of a headlamp (vehicle headlight) for a vehicle, but the present invention is also applicable to other vehicle lamps and vehicle decoration devices. can do. In the above-described embodiment, the skin layer 2 of TPU is formed on the outer surface of the lens 1 by two-color molding.
The TPU skin layer 2 may be formed on the inner surface and the inner and outer surfaces of the lens 1 by two-color molding.

[0013]

As is apparent from the above description, since the TPU skin layer is formed on the surface of the lens by two-color molding, the abrasion resistance and repulsion of the TPU skin layer are obtained. The elasticity, elasticity, and strength can surely protect the lens from being scratched, broken, attacked by chemical supplies, and the like, and can reliably prevent scattering of lens fragments when the lens is damaged. Furthermore, due to the two-color molding with the lens, the adhesion to the lens is good, and the productivity is good.
Equipment cost can be reduced, and it is environmentally preferable without using an organic solvent.
