Abstract
The utility model discloses a constant voltage car rear combination lamp, including lamp body and lens, the air vent has been seted up on the lamp body, be provided with the flexbleJoint on the lamp body, flexbleJoint one end is sealed, the other end and air vent intercommunication, a plurality of has been seted up to the air vent, a plurality of air vent distributes in the edge of lamp body, be provided with auxiliary light source in the air vent, leave the gap between auxiliary light source and the air vent, the utility model discloses keep rear combination lamp airtight, and gaseous pressure between effectual automatically regulated lamp body and the lens, make it keep invariable, avoid the gas pressure unstability to cause influence, increase of service life to the sealing washer.
Description
Technical field
This utility model belongs to rear combined lamp of automobile field, more specifically to a kind of constant voltage rear combined lamp of automobile.
Background technology
Rear combined lamp of automobile is when lighting and close, temperature spread in rear combination lamp is larger, pore is generally opened up on the lamp housing of rear combination lamp, when rear combination lamp is lighted, the hot-air between lamp housing and lens is discharged outside rear combination lamp, thus playing the effect of radiating and pressure release, otherwise outside air is sucked in rear combination lamp, meanwhile, the moisture of in the air and dust are also drawn in lens, lead to rear combination lamp to haze impact printing opacity.
The rear combined lamp of automobile having at present is enclosed, so when rear combination lamp is lighted, gas between lamp housing and lens is heated, pressure increases, and when rear combination lamp extinguishes, the air pressure between lamp housing and lens reduces, the larger area of the temperature difference particularly in one day, as the Chinese north, too low in nocturnal temperature, lead to the air pressure between lamp housing and lens very low；For airtight rear combination lamp, when the air pressure between lamp housing and lens is higher, move out promoting seal ring part on rear combination lamp, when otherwise air pressure is relatively low, sealing ring will be made to attract to the inside of rear combination lamp, if things go on like this, at sealing ring, be susceptible to fatigue or damage.
Utility model content
For the deficiencies in the prior art, this utility model provides one kind and keeps rear combination lamp airtight, and effectively automatically adjusts the pressure of gas between lamp housing and lens so as to keep constant, avoid the constant voltage rear combined lamp of automobile that gas pressure is unstable to be impacted, and increases the service life to sealing ring.
For achieving the above object, this utility model provides a kind of following technical scheme: constant voltage rear combined lamp of automobile, including lamp housing and lens, passage is offered on described lamp housing, it is provided with FlexbleJoint on described lamp housing, the closing of described FlexbleJoint one end, the other end is connected with passage.
Further the top of described lamp housing and bottom are provided with passage, and the passage of described top and bottom is connected to FlexbleJoint by pipeline.
Further described passage offers several, and several passages described are distributed in the edge of lamp housing.
Further described ventilation in the hole is provided with secondary light source, leaves gap between described secondary light source and passage.
Further described secondary light source is side-marker lamp.
Compared with prior art, the beneficial effects of the utility model are: by opening up passage on lamp housing, passage is connected with FlexbleJoint again, whole rear combination lamp internal gas are made to be in closed state, seamless or hole is swapped with extraneous air, in rear combination lamp, temperature changes, when internal gas pressure changes, gas between lamp housing and lens will be by vent flow, by FlexbleJoint flexible balancing gas pressure between whole lamp housing and lens, the sealing ring on rear combination lamp is avoided to lead to because of pressure change damage or sealing effectiveness reduction, because no extraneous air enters between lens and lamp housing, and then avoid steam to enter, so that lens inner surface cannot be hazed and affect printing opacity.
Brief description
Fig. 1 is the structural representation of this utility model constant voltage rear combined lamp of automobile；
Fig. 2 is the front view of this utility model constant voltage rear combined lamp of automobile.
Reference: 1, lamp housing；16th, passage；2nd, lens；5th, secondary light source；6th, FlexbleJoint.
Specific embodiment
The embodiment to this utility model constant voltage rear combined lamp of automobile that sees figures.1.and.2 is described further.
A kind of constant voltage rear combined lamp of automobile, including lamp housing 1 and lens 2, passage 16 is offered on described lamp housing 1, it is provided with FlexbleJoint 6 on described lamp housing 1, the closing of described FlexbleJoint 6 one end, the other end is connected with passage 16, is connected by pipeline between the preferred FlexbleJoint of the present embodiment 6 and passage 16.
When rear combination lamp lights internal gas pressure increase, portion gas will be discharged by passage 16, and gases at high pressure will promote FlexbleJoint 6, so that FlexbleJoint 6 is extended, to reduce gas pressure between whole lamp housing 1 and lens 2；Otherwise during reduced pressure, FlexbleJoint 6 will shrink, and make portion gas pass through passage 16 and be back between rear combination lamp and lamp housing 1, entirely adjust pressure equalization process, it is only the gas flowing between lamp housing 1 and lens 2, do not swap with outside air.
The preferably described passage 16 of the present embodiment offers several, and several passages 16 described are distributed in the edge of lamp housing 1, and multiple passages 16 increase gas exchange flow efficiency.
It is provided with secondary light source 5 in the preferably described passage 16 of the present embodiment, gap is left between described secondary light source 5 and passage 16, several secondary light sources 5 form side-marker lamp, gap between secondary light source 5 and passage 16 can ensure the flowing of gas, secondary light source 5 can increase the printing opacity brightness of whole rear combination lamp, and the side-marker lamp being formed make attractive in appearance at passage 16.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonging under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, some improvements and modifications under the premise of without departing from this utility model principle, these improvements and modifications also should be regarded as protection domain of the present utility model.
