Description
Technical field
The invention belongs to automobile technical field, relate to the automatic cleaning control device of a kind of automotive license plate.
Background technology
Road driving on operating motor vehicles, should hang automotive number plate, places the mark that is up to the standards, insurance mark, and carries vehicle registration certificate with car.Along with the appearance of new traffic law, about deliberately blocking, the punishment being in 12 points that is stained, not as prescribed fitting machine motor-car number plate, this regulation adds the worry of most automobile driver, because the road conditions of inclement weather or bad luck cause car plate to be blocked by mud, dirty snow and do not see license plate number unintentionally, if cleaned not in time, then belong to the mal-practice blocking car plate, by the punishment of being imposed a fine and deduct points.
The method that current most of car owner cleans car plate is manually clean, but manually clean cannot to accomplish to keep car plate at any time clean, as found at chaufeur, car plate has and stainedly but do not have water source to clean in time, is easy to violate " traffic law " requirement, makes car owner be subject to the punishment of relevant department.
For above-mentioned Problems existing, Chinese patent literature discloses a kind of car plate washing equipment [application number: CN201220330535.1], and comprise control module, switch and execution module, described switch is connected with the input end of control module; Described execution module comprises the liquid reserve tank, washer pump, delivery hose and the nozzle that connect successively, stores cleansing fluid in described liquid reserve tank, and the liquid reserve tank of described liquid reserve tank and wiper shares; Described nozzle is positioned near car plate, and its injection direction is towards car plate; Described washer pump is connected with the mouth of described control module, and the cleansing fluid controlled in washer pump extraction liquid reserve tank by control module is delivered to nozzle through delivery hose, and is gone out by nozzle ejection.Although this car plate washing equipment can clean in time to car plate, and it is easy to use, without the need to Manual-cleaning, the cleaning of car plate before and after but this car plate washing equipment is directly controlled by single switch, if car plate or rear car plate occur that stained needs cleans just, then can cause unnecessary waste, in addition, this car plate washing equipment will clean car plate, its nozzle must be arranged higher than car plate, such setting comparatively affects the outward appearance of vehicle, easily damages at vehicle travel process, is unfavorable for Long-Time Service.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose the automatic cleaning control device of a kind of automotive license plate, the automatic cleaning control device of this automotive license plate can clean front and back car plate respectively automatically, controls reliable, easy to use.
Object of the present invention realizes by following technical proposal: the automatic cleaning control device of a kind of automotive license plate, it is characterized in that, the automatic cleaning control device of described automotive license plate comprises microcontroller, front wash switch, rear wash switch, front car plate wiper mechanism and rear car plate wiper mechanism, described front wash switch is all connected with the input end of microcontroller with rear wash switch, described front car plate wiper mechanism and rear car plate wiper mechanism include reserve tank, water pump and nozzle, connected by delivery hose between described water pump and nozzle, also be provided with between described nozzle and delivery hose for make nozzle outreach car plate to fixed range when cleaning car plate and the injection direction of nozzle towards the telescoping mechanism of car plate, described water pump is connected with the mouth of microcontroller, described microcontroller also judges whether to drive the pump working in front car plate wiper mechanism or rear car plate wiper mechanism according to the on-off signal received for receiving the on-off signal carried by front wash switch or rear wash switch.
The automatic cleaning control device of this automotive license plate is controlled by a microcontroller, after current wash switch or rear wash switch are pressed, driving water pump is carried out work by microcontroller, simultaneous retractable mechanism controls nozzle stretches out fixed range, water pump extracts the water in reserve tank and is delivered to nozzle by delivery hose, water in reserve tank sprays from nozzle, namely sprays water to car plate, and then completes the cleaning to car plate; When quitting work under the effect of water pump after having cleaned at microcontroller, now nozzle also automatically retracts to original position under the effect of telescoping mechanism, should the automatic cleaning control device of automotive license plate can according to the difference of the degree of front and back car plate, respectively front and back car plate is cleaned, save the unnecessary wasting of resources, and can accomplish effectively to clean car plate in time, reduce the situation that car plate is blocked.
