Abstract
The invention discloses a semi-sealed ventilator for an automobile combined headlamp, which comprises a waterproof retainer ring arranged on a lamp case. The semi-sealed ventilator for the automobile combined headlamp is characterized in that the lower end of a ventilation pipe is connected with the center of the bottom part of the waterproof retainer ring, three limiting steps uniformly distributed at the bottom of the waterproof retainer ring are arranged around the lower end of the ventilation pipe, the inner wall of a ventilation sleeve is matched with the outer wall of the ventilation pipe, three wedge-shaped bulges in uniform distribution are arranged on the outer wall of the ventilation sleeve, a ventilation plaster is arranged at the upper end of the ventilation sleeve, a ventilation cap is buckled outside the ventilation sleeve, the inner wall of the ventilation cap is matched with the three uniformly distributed wedge-shaped bulges arranged on the outer wall of the ventilation sleeve, and the lower end of the ventilation cap is in contact with the three limiting steps arranged at the bottom of the waterproof retainer ring. The invention has the following advantages that water can be effectively prevented from being permeated into the combined headlamp from the ventilator, the ventilator has good ventilation capability, and the fogging in the combined headlamp is avoided.
Description
Technical field
The present invention relates to the car electrics parts, be specifically related to a kind of semienclosed combined automobile headlight gas permeable devices.
Background technology
Combined automobile headlight is an important function part on the automobile, has gathered vehicle front illumination and signal prompt effect, and cooperates vehicle body to form the important appearance characteristics of car load.Present semi-enclosed comination headlamp all is designed with air-vent, and heat exchanged with combination headlight extraneous air when the interior bulb of comination headlamp was lighted, and had guaranteed the air pressure balance in the comination headlamp lamp body.For sealing and the gas permeability that guarantees comination headlamp, this air-vent need design many structures and guarantee waterproof with dustproof, the service life of improving comination headlamp.The comination headlamp gas permeable devices is made up of the L shaped bend pipe of rubber, dustproof sponge pad and permeability cell at present.Permeability cell is the column type of hollow, links to each other with comination headlamp is inner, and its external diameter is suitable with the L shaped bend pipe internal diameter of rubber.The dustproof sponge pad is fine and close expanded material, and the centre has many apertures, and plug is fixing like the L shaped bend pipe of rubber middle part, has dustproof effect.L shaped bend pipe of rubber and permeability cell are installed together.This kind structure is prevented dust through the fine and close aperture of foam-rubber cushion, but after suction, is difficult for drying, and aqueous vapor is inhaled in the comination headlamp lamp easily, causes comination headlamp to haze.Many hidden danger such as therefore this kind ventilating structure exists waterproof ability poor, and it is serious that dustproof sponge is prone to absorb water, comination headlamp hazes.
Summary of the invention
The purpose of this invention is to provide a kind of semienclosed combined automobile headlight gas permeable devices, it can either prevent effectively that sealing from infiltrating in the comination headlamp lamp, has the high ventilation ability again, avoids hazing in the comination headlamp lamp.
A kind of semienclosed combined automobile headlight gas permeable devices of the present invention; Comprise the waterproof back-up ring that is located on the lamp housing; It is characterized in that: the lower end of a permeability cell is connected with the center of waterproof back-up ring bottom, is being provided with three limited steps that evenly divide on waterproof back-up ring bottom around the permeability cell lower end; The inwall of one ventilative cover cooperates with the outer wall of permeability cell, and three equally distributed wedge shapes on ventilative cover outer wall are protruding, is provided with ventilative the subsides in the upper end of ventilative cover; One ventilative cap is buckled in the outside of ventilative cover, and protruding cooperation of three equally distributed wedge shapes on the inwall of ventilative cap and the ventilative cover outer wall, three limited steps of lower end bottom the waterproof back-up ring of the cap of breathing freely contact.
Described a kind of semienclosed combined automobile headlight gas permeable devices is provided with the sluicing breach in a side of waterproof back-up ring.
Described a kind of semienclosed combined automobile headlight gas permeable devices, the material of its described ventilative subsides is a nonwoven, closely sticks on ventilative cover one end, has the waterproof and breathable function.
The present invention compares with prior art and has the following advantages: prevented that effectively water from penetrating in the comination headlamp lamp from this gas permeable devices, and had the high ventilation ability, avoided hazing in the comination headlamp lamp.
Description of drawings
Fig. 1 is that parts of the present invention are formed sketch map.
Fig. 2 is the cutaway view after assembling of the present invention is accomplished.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further description.
Referring to a kind of semienclosed combined automobile headlight gas permeable devices illustrated in figures 1 and 2, comprise the waterproof back-up ring 2-3 that is located on the lamp housing 2, be provided with sluicing breach 2-4 in a side of waterproof back-up ring; The lower end of one permeability cell 2-1 is connected with the center of waterproof back-up ring bottom, is being provided with three limited step 2-2 that evenly divide on waterproof back-up ring bottom around the permeability cell 2-1 lower end; The inwall of one ventilative cover 1-2 cooperates with the outer wall of permeability cell 2-1, and the protruding 1-4 of three equally distributed wedge shapes on ventilative cover outer wall is provided with the ventilative 1-3 of subsides in the upper end of ventilative cover; One ventilative cap 1-1 is buckled in the outside of ventilative cover 1-2, and the inwall of ventilative cap cooperates with protruding 1-4 of three equally distributed wedge shapes on the ventilative cover outer wall, and three the limited step 2-2s of lower end bottom the waterproof back-up ring of the cap of breathing freely contact.
The material of described ventilative subsides 1-3 is a nonwoven, closely sticks on ventilative cover one end, has the waterproof and breathable function.
