Description
Technical field
The utility model relates to a kind of servicing unit of automobile lamp, especially relates to the anti-device that hazes of a kind of automobile lamp.
Background technology
The high temperature that existing automobile front produces while opening and long-time the irradiation, make the headlight internal temperature higher, and air pressure is larger, and the hot gas in lamp body need discharge.When the car light temperature descends, the lamp body internal gas pressure descends, and needs to absorb ambient atmos to supplement air pressure.During wet weather, the gas humidity sucked in car light is higher, easily condenses into steam after entering car light, thereby affects the car lighting effect.
Chinese patent Granted publication number: CN201028450, in the patent document of on 02 27th, 2008 Granted publication day, a kind of the whole sealed type headlamp is disclosed, comprise housing, bulb, interior plug, back shroud and outside dust cover with air-vent, be provided with the semi-transparent rete of being made by nylon material between the end face of described interior plug and air-vent.The utlity model has reliable in structure, long-term use also can guarantee the advantage of sealing property and good looking appearance.But its weak point is, nylon material has temperature distortion, and easily aging characteristic, be applied in car light, be heated for a long time easily aging, and the loss of seal effect, car light also can haze.
The utility model content
The utility model is the deficiency easily hazed in order to overcome prior art car headlight, and a kind of device that can prevent that the car headlight from hazing is provided.
To achieve these goals, the utility model is by the following technical solutions:
The anti-device that hazes of a kind of automobile lamp of the present utility model, comprise the first shell that holds left front car light and the second housing that holds right front car light, described the first shell and second housing are equipped with and are communicated with extraneous breather pipe, the first shell connects an end of the first air intake duct, the other end of the first air intake duct is connected with fan room, second housing connects an end of the second air intake duct, the other end of the second air intake duct is connected with fan room, be provided with fan in fan room, fan room is provided with air outlet in the air side of fan.During fan work, air enters the space in left front car light the first shell from the external world by breather pipe, then enters fan room from the first air intake duct, then discharges from air outlet.Air Flow in right front car light is like this equally.Strengthened the convection current of air in the car light by fan, weakened and eliminate in lamp the situation that hazes.
As preferably, be provided with the first temperature sensor and the first humidity sensor in described the first shell, the first temperature sensor and the first humidity sensor all are electrically connected to the interior controller of automobile; Be provided with the second temperature sensor and the second humidity sensor in second housing, the second temperature sensor and the second humidity sensor all are electrically connected to the interior controller of automobile, and controller and fan are electrically connected to.Haze in lamp and mainly determined by two factors of temperature and humidity, mounting temperature sensor and humidity sensor, environment in the monitoring lamp, provide information, under the environment easily hazed, opens ahead of time fan, and prevention is hazed.Make demist have according to following.The first temperature sensor and the first humidity sensor, to the signal of car internal controller transmission, show the environment that hazes in left front car light, and the second temperature sensor and the second humidity sensor, to the signal of car internal controller transmission, show the environment that hazes in right front car light.Controller is controlled the fan action.
As preferably, described controller is electrically connected to a dew point arithmetic unit.According to the principle that hazes, under certain humidity, in lamp, temperature, lower than dew-point temperature, can haze.According to the strange formula of dagger-axe husband Gray, know temperature and humidity, can obtain dew-point temperature, the temperature and humidity that we can obtain by monitoring thus, calculate dew-point temperature.Then, relatively in dew-point temperature and lamp, temperature judges whether to haze, and so just can automatically control fan open and close, manually-operated again by controller.
As preferably, described the first air intake duct and the second air intake duct are flexible pipe.The convenient stringing of installing of flexible pipe.
The utlity model has following beneficial effect: (1) provided with fan, strengthen the front car light inner air convection, prevent from hazing; (2) mounting temperature sensor and humidity sensor in front car light, Real-Time Monitoring, control fan work automatically.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is schematic diagram of the present utility model.
In figure: the first shell 11, second housing 12, breather pipe 2, the first air intake duct 31, the second air intake duct 32, fan room 4, fan 5, air outlet 6, the first temperature sensor 71, the first humidity sensor 81, the second temperature sensor 72, the second humidity sensor 82.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
In embodiment as shown in Figure 1, the anti-device that hazes of a kind of automobile lamp, comprise the first shell 11 that holds left front car light and the second housing 12 that holds right front car light, the first shell 11 and second housing 12 are equipped with and are communicated with extraneous breather pipe 2, the first shell 11 connects an end of the first air intake duct 31, the other end of the first air intake duct 31 is connected with fan room 4, and second housing 12 connects an end of the second air intake duct 32, and the other end of the second air intake duct 32 is connected with fan room 4.Fan room 4 is arranged on the engine nacelle front beam, and 4 li of fan room are provided with fan 5, and fan room 4 is provided with air outlet 6 in the air side of fan 5.Being provided with the first temperature sensor 71 and the first humidity sensor 81, the first temperature sensors 71 and the first humidity sensor 81 in the first shell 11 all is electrically connected to the interior controller of automobile.Being provided with the second temperature sensor 72 and the second humidity sensor 82, the second temperature sensors 72 and the second humidity sensor 82 in second housing 12 all is electrically connected to the interior controller of automobile.Controller and fan 5 are electrically connected to.Temperature sensor is specially resistance thermometer, and humidity sensor is specially resistive moisture sensor, and controller is specifically the ECU controller.Controller is electrically connected to a dew point arithmetic unit.
