Description
Technical field
The present invention relates to a kind of headlight for vehicles cover surfaces to remove accumulated snow method.
Background technique
In the prior art, battle wagon has a kind of function of being vehicle headlamp cleaning, is mainly used for northern area, fits
The area more for snowfall.Due to frequent snowfall, heavy snow is easy to come in headlight surface heap, to shelter from the photograph of headlight
Area pellucida domain influences the safety of driving at night.Headlight accumulated snow is cleared up since driver cannot often stop, it is therefore desirable to have phase
The automatic snow equipment answered.In order to solve this problem, the method used in the prior art is to increase headlight automatic cleaning function,
Think to spray water flow on headlight by the nozzle below headlight to realize the removing of accumulated snow on headlight.However, this technology is deposited
In two disadvantages, first is that driver's itself is unsighted in heavy snow, it is difficult accurately to judge the accumulated snow on headlight
Whether amount needs manually opened headlight cleaning function, and headlight cleaning function is unable to continuous service；Second is that spraying water to headlight surface
It is easy to cause headlight surface to freeze, ice face causes the variation of light angle, jeopardizes the row of other side driving driver and driver
Vehicle safety.
Summary of the invention
Goal of the invention: being directed to the above-mentioned prior art, proposes that a kind of headlight for vehicles cover surface removes accumulated snow method, can be automatic
It realizes and achievees the effect that continuous removing car light accumulated snow for a long time by heating headlight lampshade.
Technical solution: a kind of headlight for vehicles cover surface removes accumulated snow method, be equipped in the headlight lampshade transparent electricity plus
The marginal position of headlight lampshade is arranged in hot interlayer, the electrode of transparent electric heating interlayer, and the cover surface side is equipped with and is used for
The photoelectric sensor of cover surface Snow Thickness is detected, the electrode connects power circuit, and the photoelectric sensor connects micro- place
The signal input part of device is managed, the signal output end of the microprocessor connects the power circuit；
Step 1: the microprocessor receives vehicle for detecting the signal of outdoor temperature sensor, when the microprocessor first
When detecting that outdoor temperature is higher than zero degrees celsius, microprocessor controls each equipment and does not work, when detecting outdoor temperature lower than zero
Degree Celsius when, start reading out the signal of the photoelectric sensor；
Step 2: the microprocessor carries out the judgement of cover surface Snow Thickness according to the output signal of photoelectric sensor, works as lampshade
When surface Snow Thickness is greater than given threshold, the power circuit is output a control signal to, controlling power circuit exports specified electricity
Stream；
Step 3: after electric heating interlayer continues working and melts the accumulated snow on headlight lampshade, the microprocessor detects lamp
When covering surface Snow Thickness less than 0.5 ~ 0.8 times of threshold value, the specified function that the power circuit exports 0.5 ~ 0.8 times is controlled
Rate.
Further, the step 3 further includes controlling described 0.5 ~ 0.8 times of power circuit output of rated power dimension
It is described when the microprocessor detects that cover surface Snow Thickness is consistently less than the given threshold when holding 10 ~ 15 minutes
Microprocessor closes the output of the power circuit.
Further, the given threshold is 0.2 ~ 0.3 millimeter.
The utility model has the advantages that a kind of headlight for vehicles cover surface of the invention removes accumulated snow method, by vehicle for outside sensing chamber
Whether the signal detection outdoor temperature of temperature sensor is less than zero degree to control the start and stop of electric heating system snow removal system, then root
The electric heating starting of transparent electric heating interlayer is controlled according to the signal of the photoelectric sensor for detecting cover surface Snow Thickness,
Finally when cover surface Snow Thickness be less than preset threshold, that is, when having little influence on illumination, maintain the low of transparent electric heating interlayer
It is carried out after when one section of power work fully powered-off.It realizes that cover surface heats snow removal function by transparent electric heating interlayer, is
System can automatically turn on or close system according to the detection of sensor, automatical and efficient and energy saving.Last lasting low-power
Power supply, can maintain certain heating temperature, when Snow Thickness increases again, electric heating system can be fast whithin a period of time
Speed reaction, saves the time.
Specific embodiment
Further explanation is done to the present invention below.
A kind of headlight for vehicles cover surface removes accumulated snow method, based on hardware be equipped in headlight lampshade transparent electricity plus
The marginal position of headlight lampshade is arranged in hot interlayer, the electrode of transparent electric heating interlayer, and cover surface side is equipped with for detecting
The photoelectric sensor of cover surface Snow Thickness, electrode connect power circuit, and the signal that photoelectric sensor connects microprocessor is defeated
Enter end, the signal output end of microprocessor connects power circuit.Wherein, electric heating layer is metal-oxide film, metal oxidation
Object film is incorporated in glass or plastics headlight lampshade by high temperature precompressed and high-temperature high-pressure craft.
In order to enable the edge of metal-oxide film transparency equally with higher, the applicant after study, is created
The property made is the metal oxide electrode formed using exposure cracking film as templated deposition metal platinum network, is produced by the method
Electrode transparency with higher, and thickness is small, resistance is small, electric conductivity is stable.
Metal-oxide film is that platinum oxide coating is coated in insulation transparent substrate with meteorological growth method to be formed, and is insulated
Transparent substrates are the film that polyvinyl butyral resin is plasticized extrusion forming through plasticizer.Using polyvinyl butyral resin
Film and plastics or glass headlight through plasticizer plasticizing extrusion forming all have preferably can amalgamation, be plasticized and squeeze through plasticizer
Also there is certain impact resistance after molded, can play a protective role to especially plastic lamp shade.Film surface is coated with
Antioxidant can slow down aging of electric heating layer under the action of ultraviolet light significantly, to postpone the service life of headlight.
Step 1: microprocessor receives vehicle for detecting the signal of outdoor temperature sensor, when microprocessor detects first
When being higher than zero degrees celsius to outdoor temperature, microprocessor controls each equipment and does not work, when detecting that outdoor temperature is Celsius lower than zero
When spending, the signal of the photoelectric sensor is started reading out.
Step 2: microprocessor carries out the judgement of cover surface Snow Thickness according to the output signal of photoelectric sensor, works as lampshade
When surface Snow Thickness is greater than given threshold, the power circuit is output a control signal to, controlling power circuit exports specified electricity
Stream；Given threshold is 0.2 ~ 0.3 millimeter.
Step 3: after electric heating interlayer continues working and melts the accumulated snow on headlight lampshade, microprocessor detects lamp
When covering surface Snow Thickness less than 0.5 ~ 0.8 times of threshold value, the specified function that the power circuit exports 0.5 ~ 0.8 times is controlled
Rate.When the rated power that controlling power circuit exports 0.5 ~ 0.8 times maintains 10 ~ 15 minutes, when microprocessor detects lampshade
When surface Snow Thickness is consistently less than given threshold, microprocessor closes the output of the power circuit, energy saving.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
