Abstract
The invention relates to a full-sealed structure of an automobile headlamp. The full-sealed structure comprises a lens and a lamp housing. The edge of the lens is matched with a glue groove of the lamp housing and sealed by PUR glue. The full-sealed structure is characterized in that the lower portion of the lamp housing is provided with a self-balancing valve; and a self-balancing balloon is connected with the self-balancing valve in a matching mode and communicated with an inner cavity of a lamp body. The full-sealed structure of the automobile headlamp has following beneficial effects: reliable sealing performance is obtained; the headlamp is prevented against water ingress due to fogging; the headlamp can be used in harsh weather; and illuminance of ground of the headlamp is ensured in favor of driving safety.
Description
Technical field
The present invention relates to automotive lighting element structure, be specifically related to
a kind of automobile front all-sealed structure.
Background technology
Current automobile front generally adopts Semi-seal structure, and namely lamp chamber is exchanged with outside air by ventilated membrane or Ventilated cap, balance because of lighting or light-off cause inside and outside atm difference.Common semitight measure has following two kinds:
Middle and high end light fixture generally all adopts the Ventilated cap form of breather pipe+filter cloth (one-way ventilating membrane technology) enter in lamp body to prevent aqueous water and keep air pressure balance, general low side Ventilated cap adopts U-shaped gum cover to add screen pack to realize maintenance light fixture internal and external pressure balance, air exchange situation.
No matter above which kind of form, so long as not hermetically sealed light fixture, in serious moist environment, use light fixture, air humidity in light fixture can be caused to strengthen, meet condensation knot, water smoke is formed in lamp distribution mirror inside, not only affect light fixture appearance looks elegant, cause client to complain, use in bad weather, greatly affect light fixture illuminance of ground, bring potential safety hazard to driver's life.
A kind of the whole sealed type headlamp disclosed in CN 201028450 U, comprises with the housing of air-vent, bulb, interior plug, back shroud and outside dust cover, it is characterized in that being provided with the semi-transparent rete be made up of nylon material between said interior plug and the end face of air-vent.Mainly solve the shortcoming that housing seal performance obviously declines, inside often there will be condensation vapor that existing automobile front exists.Should
utility modelhave that structure is reliable, Long-Time Service also can ensure sealing property and the advantage of good looking appearance.This is a kind of good try beyond doubt.
Summary of the invention
The object of this invention is to provide
a kind of automobile front all-sealed structure, its sealing is reliable, and the phenomenon that headlight easily hazes into water can be avoided to occur, and can use in bad weather, guarantee headlight illuminance of ground, is conducive to traffic safety.
Of the present invention
a kind of automobile front all-sealed structure, comprise lens, lamp housing, edge and the glue slot fit be located on lamp housing of described lens, and sealed by PUR glue, it is characterized in that: described lamp housing bottom is provided with self-balancing valve, a self-balancing balloon and this self-balancing valve are connected, and communicate with lamp body inner chamber.Like this, lamp body inner chamber is just hedged off from the outer world completely, need not carry out air-flow exchange.Thus avoid the phenomenon that headlight easily hazes into water and occur, even if use in bad weather, also ensure headlight illuminance of ground, guarantee driving safety.
Described
a kind of automobile front all-sealed structure, described in it, the material of self-balancing balloon is resistant to elevated temperatures ethylene propylene diene rubber.
Further, described self-balancing balloon is connected with the self-balancing valve interference fit of described lamp housing bottom.
The present invention does not arrange the Ventilated cap carrying out air exchange with environment, therefore air humidity in light fixture can be avoided to strengthen, and light fixture hazes into this operating mode of water.Communicate with self-balancing balloon by arranging lamp housing in lamp body bottom, under light fixture lighting operating mode, the air of expanded by heating can pour in the space in self-balancing balloon, maintains internal and external pressure balance simultaneously.
Beneficial effect of the present invention is specifically:
(1) avoid water inlet that semitight light fixture easily causes to haze phenomenon, reduce light fixture after-sales service number;
(2) eliminate expensive semitight Ventilated cap, ventilated membrane material, reduces light fixture production cost;
(3) adopt resistant to elevated temperatures ethylene propylene diene rubber balloon to carry out air pressure balance, easy large-scale promotion is produced.
Accompanying drawing explanation
figure1 is traditional semi-enclosed headlight signal
figure;
figure2 is signal of the present invention
figure.
figurein: 1-first wife light microscopic, the former lamp housing of 2-, the former fluid sealant of 3-, the former Ventilated cap of 4-;
11-lens, 12-lamp housing, 13-fluid sealant, 14-self-balancing balloon.
Detailed description of the invention
Below in conjunction with attached
figurethe present invention is further illustrated with traditional semi-enclosed headlight.
See
figuretraditional semi-enclosed headlight shown in 1, comprise first wife's light microscopic 1, former lamp housing 2, former fluid sealant 3(plays and connects and seal lens and lamp housing effect, steam is stoped to enter in lamp body), former Ventilated cap 4 is arranged in lamp housing rear portion, plays ventilating air, keep inside and outside air pressure balance, but also bring the risk that moisture enters lamp body simultaneously.Hydrone in air enters lamp body through Ventilated cap, and easily condense on lens, formation is hazed.

figureshown in 2
a kind of automobile front all-sealed structure, comprise lens 11, lamp housing 12, the edge of described lens coordinates with the glue groove 13 be located on lamp housing, and sealed by PUR glue, it is characterized in that: described lamp housing 12 bottom is provided with self-balancing valve, a self-balancing balloon 14 is connected with this self-balancing valve, and communicates with lamp body inner chamber.
Described
a kind of automobile front all-sealed structure, described in it, the material of self-balancing balloon 14 is resistant to elevated temperatures ethylene propylene diene rubber.Ethylene propylene diene rubber through the rubber of solution copolymerization, then introduces Third monomer (ENB) by ethene, propylene.Ethylene propylene diene rubber (EPDM) ozone resistance, heat resistance, weatherability, low-temperature pliability are better.
Further, described self-balancing balloon 14 is connected with the self-balancing valve interference fit of described lamp housing 12 bottom.
The present invention, owing to eliminating Ventilated cap, arranges a self-balancing valve in lamp housing bottom, and increases a resistant to elevated temperatures self-balancing balloon, and elastic conjunction is on lamp housing; Under light fixture lighting operating mode, the air of expanded by heating can pour in the space in self-balancing balloon, and self-balancing balloon is in order to balance the change of lamp body internal gas pressure.The present invention is simple, and by cae analysis, it is applicable to each operating mode of light fixture completely, overcomes semitight headlight and easily hazes into the phenomenon of water.
