Description

Automobile head light lampshade
Technical field
The present invention relates to a kind of automobile lamp spare and accessory parts, particularly relate to a kind of automobile head light lampshade.
Background technology
Along with the high speed development of auto industry, people pursuit comfortableness and easily handling while, the security of Integral automobile and energy-conserving and environment-protective are also more and more paid attention to.To this, automobiles headlamp now more to be used LED and adopts plane cluster encapsulation technology, can realize requirement that is high-power, low energy consumption; But, in prior art, in order to prevent entering of rainwater, headlamp lampshade adopts airtight form usually, is fastened on headlamp, when automobile head light is in illumination condition, closed environment residing for it will produce higher temperature due to heat accumulation, this higher temperature is not only easy produces fog in car light inside, affects illuminating effect, also easily make the parts temperature distortion in automobile lamp, even occur the phenomenon of parts scorification.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of automobile head light lampshade of new structure, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide the temperature difference inside and outside a kind of active balance headlamp, effectively preventing the automobile head light lampshade of fog and parts temperature distortion situation.
Automobile head light lampshade of the present invention, comprise cover body and backboard, the front bottom end of described cover body is provided with air inlet and is provided with the deep bead of upward opening in the inner side of air inlet, surround air intake passage inside described deep bead and described cover body, described air intake passage is disposed with the first filtering meshes, water barrier, the second filtering meshes and water accepting layer from outside to inside; The top, rear end of described cover body and bottom are respectively arranged with exhaust outlet and lower exhaust outlet, and the outside of described upper exhaust outlet and lower exhaust outlet is all connected with the mozzle to centre bending.
Further, described first filtering meshes is metal filter screen, and described second filtering meshes is polysiloxane film.
Further, described water barrier is glass fibre water barrier, and described water accepting layer is active carbon water accepting layer.
Further, the position described deep bead being positioned at active carbon water accepting layer is shadow shield.
Further, described deep bead is arc, and the spacing between described deep bead and cover body diminishes in direction from outside to inside gradually along air intake passage.
Further, the inner side being positioned at described lower exhaust outlet bottom described cover body is also provided with water collection sheet, and the inner side described cover body being positioned at water collection sheet is provided with discharge outlet.
Concrete, the aperture inside described discharge outlet is greater than the aperture in outside.
Further, described backboard is provided with the mount pad for installation of heat radiator, the inner side of described mount pad is provided with internal thread.
By such scheme, the present invention at least has the following advantages: due to cover body being provided with air inlet, and the first filtering meshes, water barrier, the second filtering meshes and water accepting layer play successively drainage, water proof, hydrophobic and water suction effect, like this, automobile is in the process of advancing, under the pressure of air flowing, dry cold air can enter in cover body, and discharge through exhaust outlet, play the effect of cooling radiator further, effectively improve radiating efficiency, and owing to balancing the temperature of both sides inside and outside LED, make can not haze in headlamp.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
Accompanying drawing explanation
Fig. 1 is sectional view of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Shown in Figure 1, a kind of automobile head light lampshade, the backboard 2 comprising cover body 1 and be fixed on rear side of cover body, the front bottom end of cover body 1 is provided with air inlet 11 and is provided with the deep bead 3 of upward opening in the inner side of air inlet 11, surround air intake passage inside deep bead 3 and cover body 1, air intake passage is disposed with the first filtering meshes 4, water barrier 5, second filtering meshes 6 and water accepting layer 7 from outside to inside; The top, rear end of cover body 1 and bottom are respectively arranged with exhaust outlet 12 and lower exhaust outlet 13, and the outside of upper exhaust outlet 12 and lower exhaust outlet 13 is all connected with the mozzle 8 to centre bending; During installation, be fixed on by cover body on radiator 10, the front side of radiator and rear side are respectively arranged with LED light source 20 and LED power 30; Due to cover body being provided with air inlet, and the first filtering meshes, water barrier, the second filtering meshes and water accepting layer play successively drainage, water proof, hydrophobic and water suction effect, like this, automobile in the process of advancing, air flowing pressure under, dry cold air can enter in cover body, and discharge through exhaust outlet, play the effect of cooling radiator further, effectively improve radiating efficiency, and owing to balancing the temperature of both sides inside and outside LED, make can not haze in headlamp.
In order to effectively play drainage and hydrophobic effect, automobile head light lampshade of the present invention, the first filtering meshes 4 is metal filter screen, and the second filtering meshes 6 is polysiloxane film, and polysiloxane film is waterproof and breathable material.
In order to effectively play the effect of water proof and water suction, automobile head light lampshade of the present invention, water barrier 5 is glass fibre water barrier, and water accepting layer 7 is active carbon water accepting layer; In order to prevent the direct illumination of LED at activated carbon surface, cause temperature to raise and make active carbon spontaneous combustion, position deep bead 3 being positioned at active carbon water accepting layer is shadow shield 31.
In order to make the cold air entered be attached to lampshade inner surface flowing, prevent lampshade from hazing, automobile head light lampshade of the present invention, deep bead 3 is arc, and the spacing between deep bead 3 and cover body 1 diminishes in direction from outside to inside gradually along air intake passage.
