Description
Technical field
The utility model relates to technical field of automobile parts, more particularly to a kind of anti-car light and automobile to haze.
Background technique
Car light fog is always the hard nut to crack for perplexing components and vehicle enterprise.On the one hand, vehicle lamp assembly and single-item
Part will meet the experiment condition of various harshnesses, and common actual effect mode has lens to haze, lens current mark, fog are not being advised
It fixes time inner dissipation etc.；On the other hand, lamps and lanterns often occur when road test sport car and vehicle zero kilometer are stored in extreme circumstances
Anti-fog coating actual effect, shows as albefaction, and the problem of appearance such as condensation, the harmless satisfaction for reaching client occurs in current mark.
In view of the above-mentioned problems, so far, the scheme for improving car light fog can divide three classes.The first is also most common side
Method surveys spraying that is, in lens or showering anti-fog coating, the principle of this method is to make fog using the hydrophily of coating surface
It is not easy " being seen ", therefore can not solve the problems, such as fog from source, meanwhile, anti-fog coating itself is difficult to the defect overcome usually
Current mark and albefaction problem are bred, lamps and lanterns cost is increased；Second method is that a certain number of desiccant are arranged in lamps and lanterns, is led to
It crosses desiccant and absorbs humidity in moisture reduction lamp chamber.However, desiccant, which can not change, matches under the experimental situation of certain harshnesses
Light microscopic temperature is rapidly reduced to the fog problem occurred under air dew point value, moreover, desiccant has certain timeliness, moisture absorption
Effect on moisture extraction will be lost after saturation；The third scheme increases the parts such as vent cap or ventilated membrane on lamp casing, improves lamp chamber
Interior air circulation reduces air setting by the method for convection current or diffusion and adjusts air pressure balance.Similarly, when ambient humidity very
When big, the principle of ventilated membrane itself can not completely cut off steam and enter cavity, still suffer from the risk that hazes.
With automobile lamp moulding increasingly flattening, integrated, it is difficult to evade local air circulation in structure design unsmooth
The problem of.Design of ventilation is mostly used using the prior art that desiccant improves car light fog, for example, snorkel is (with or without sea
It is continuous), vent cap (cap), vent membrane etc., the extraneous air entered in car light is dried using desiccant, is prevented in car light
Portion hazes.
Utility model content
The utility model provides a kind of anti-car light to haze, which can not only be greatly reduced cost, subtracts
Unnecessary part and surface treatment are gone, large-scale batch production mode is suitble to；It can also prevent from hazing inside car light.
To achieve the goals above, the utility model first aspect provides a kind of anti-car light to haze, including lamp body and matches

Preferably, the lamp body and lens fasten, and are tightly connected between the two.Fundamentally control sealing cavity
Interior humidity.
Preferably, the lamp body and lens are sealed by sealant, the sealant be silica gel, Reactive hot melt adhesive,
At least one of butyl rubber and pressure sensitive adhesive.
Preferably, the desiccant is at least one of magnesium chloride, magnesia, calcium chloride and silica gel.It ensure that sealing
Dry environment in cavity.
Preferably, the lens inner surface is coated with anti-fog coating.The fog in car light is further prevented, is obtained more preferable
Anti- fog effect.
Preferably, the car light is equipped with or is formed with elastic portion.
Preferably, the elastic portion is rear cover made of the elastic material that is arranged on the lamp body.Sealing is effectively relieved
Pressure change in cavity protects each component of car light, extends the service life of car light and its component.
Preferably, the elastic material be rubber material, the rubber material include EPDM (EP rubbers), silicon rubber,
TPE (thermoplastic elastomer (TPE)), butyl rubber.
The utility model second aspect provides a kind of automobile, including preventing described in any one of first aspect technical solution
The car light of mist.
Through the above technical solutions, the utility model has the beneficial effects that
Lamp body and lens snap together to form sealing cavity, fundamentally control the humidity in lamp chamber, evade
Anti-fog coating is easy to produce the defect of current mark and albefaction, in combination with the effect on moisture extraction of the desiccant in sealing cavity；From basic
On improve the antifog designs of existing lamps and lanterns, that is, the Design of ventilation used in the antifog design of existing lamps and lanterns is eliminated, for example, logical
Tracheae (with or without sponge), vent cap (cap), vent membrane etc., lens inner surface can cancel antifog processing, in turn, energy
Cost is enough greatly reduced；It is suitble to large-scale batch production mode, the satisfaction of client can be reached；
Desiccant in sealing cavity can dynamic regulation sealing cavity temperature and humidity balance, guarantee the drying ring inside car light
Border；Furthermore, it is possible to effectively extend the service life of desiccant, desiccant service life can reach -10 years 3 months；
Air pressure change range in sealing cavity is 0-20KPa, and setting has the rear cover of certain elasticity on lamp body, when by
When air pressure change in sealing cavity, rear cover dilation alleviates the pressure in sealing cavity, reduces to each component of car light
It influences, extends the service life of car light and its component.
