A kind of high sealing automobile clearance lamps
Technical field
This utility model relates to automobile lamp technical field, particularly relates to a kind of high sealing automobile
Clearance lamps.
Background technology
The clearance lamps that after passenger vehicle, upper part is installed at present, mounting means is mainly by being beaten by glue
Enter in the entrucking hole on passenger vehicle, after light fixture is pressed against in entrucking hole, by glue, both are entered
Row is fixing to be connected;But this mounting means is very inconvenient, and light fixture the most easily occurs
Surface is uneven with entrucking interporal lacuna, and outward appearance is unsightly.
Additionally the lamp interior useful space is the least, and part material heat resistance is poor, the heat-resisting temperature of material
Not, the phenomenons such as poorly sealed at lamp holder hole, light fixture spatial design portion is reasonable cause degree.
But the heat that high sealing performance makes car light produce cannot come out, the most outward
The service life of automobile lamp can be affected.So ensureing the same of automobile lamp high sealing performance
Time, the heat radiation of rational design vehicle car light, serviceability and the service life to automobile lamp
There is strong influence.Additionally the requirement of light fixture is also constantly being promoted, to light fixture by client now
Aesthetic property it is also proposed new requirement, light fixture should its luminous intensity distribution performance country to be met attractive in appearance
Standard-required.
Summary of the invention
According to the problems referred to above, the purpose of this utility model is to provide a kind of high sealing automobile to show exterior feature
Lamp, its object is to improve automobile lamp, the especially brightness of automobile clearance lamps, and at height
The time worked under temperature environment, improve the weatherability of car light, thus improve automobile lamp and brought
Potential safety hazard, and ensure that the service life that car light is longer simultaneously.
The technical solution of the utility model is achieved in the following ways: a kind of high sealing automobile
Clearance lamps, including lampshade, lamp housing, described lampshade and lamp housing are tightly connected shape by welding procedure
Becoming a cavity, described lamp housing is provided with reverberation bowl, and reverberation bowl is provided with bulb mounting hole,
Light source assembly is installed on bulb mounting hole;It is characterized in that: the described lamp housing back side is provided with
Venthole, venthole is pasted with ventilated membrane, and the inner surface of lamp housing is provided with aluminium coated.
Described light source assembly is made up of with light source seal cartridge, and the liner body part of seal cartridge is interior
The double-decker of portion's hollow.
The material of described lamp housing is engineering plastic alloy PC+ABS.
The described lamp housing back side also limit mounting has the foam pad that EPDM material does, and passes through foam pad
Prevent lamp housing from colliding with vehicle body mounting portion, during lamp housing and lampshade after welding are welded
Connect the welded seal part cracking that the internal stresses release in part occurs, cause light fixture to leak.
This utility model, improves the utilization of light by clearance lamps inner surface aluminium coated and reverberation bowl
Rate, improves the brightness of automobile clearance lamps, thus improves the potential safety hazard that automobile lamp is brought,
And ensure that the service life that car light is longer simultaneously.
Accompanying drawing explanation
Fig. 1 is sectional structure chart of the present utility model.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with the accompanying drawings with embodiment to this practicality
Novel further illustrating, this embodiment is only used for explaining this utility model, to this practicality newly
The protection domain of type constitutes restriction.
Known by Fig. 1, a kind of high sealing automobile clearance lamps, including lampshade 1, lamp housing 2, described
Lampshade 1 is tightly connected one cavity of formation, described lamp housing 2 with lamp housing 2 by welding procedure
Being provided with reverberation bowl 3, reverberation bowl 3 is provided with bulb mounting hole 4, and bulb mounting hole 4 is pacified
Equipped with light source assembly 5;Described light source assembly 5 is made up of with light source 52 seal cartridge 51, close
The double-decker that liner body part is inner hollow of envelope lining 51, sealing effectiveness is more preferable.Lamp housing
2 back sides are provided with venthole 6, and venthole 6 is pasted with ventilated membrane 7, by ventilated membrane 7
Rapidly the temperature in cavity can be reduced;The inner surface of lamp housing 2 is provided with aluminium coated.Described
The material of lamp housing 2 is engineering plastic alloy PC+ABS, i.e. Merlon and acrylonitrile-butadiene
-styrol copolymer and mixture, be that the heat by Merlon and polyacrylonitrile alloy can
Plasticity plastic cement, has stronger mechanical performance and good processing performance, thus improves lamp housing
Heat-resisting and the weatherability of 2.Described lamp housing 2 back side also limit mounting has what EPDM material did to send out
Bubble pad 8, prevents lamp housing 2 from colliding with vehicle body mounting portion by foam pad 8, during
The welded seal that lamp housing 2 after welding is occurred with the internal stresses release in lampshade 1 welding portion
Part cracking, causes light fixture to leak.By clearance lamps lamp housing 2 inner surface aluminium coated and reverberation bowl
3 utilization rates improving light, improve the brightness of automobile clearance lamps, thus improve automobile lamp and carried
The potential safety hazard come, and ensure that the service life that car light is longer simultaneously.
What embodiment of the present utility model was announced is preferred embodiment, but is not limited thereto,
Those of ordinary skill in the art, easily according to above-described embodiment, understands essence of the present utility model
God, and make different amplifications and change, but as long as without departing from spirit of the present utility model, all
In protection domain of the present utility model.
