Abstract
The utility model discloses the daily automatic cleaning system of a kind of shield glass, comprise wiper assembly, sensor, light source and control circuit.Wherein, the light that infrared light supply sends is received by sensor, and in sensor Access Control circuit, control circuit and wiper assembly access in power circuit jointly, and when dust is many, the light of reception is few, and control circuit controls wiper assembly and carries out work; When cleaning clean, control circuit makes power circuit disconnect, and wiper quits work.The utility model is reliable and stable, and structure is simple, eliminates the impact of sight line on navigating mate, enhances driving safety.
Description
Technical field
The utility model relates to a kind of shield glass automatic cleaning system, especially relates to a kind of daily washing system carrying out work according to the amount of dust on Windshield.
Background technology
Usual windscree for vehicle rain brush cleans windshield, so that chaufeur can be clear that outside when sleety weather is driven.Rain brush is the cleanout tool of each car indispensability, on rainy day, snowy day, can use under the weather that even dust such as dense fog is more, object is the sight line in order to allow front windshield can not block person for driving a car because of too dirty, prevent the traffic accident problem caused because of this kind of hardware problem, but present automatic induction rain brush is all carry out work according to Raindrop sensor module, and when fine day, keeping out the wind still needs manual operation to the cleaning of glass, not only inconvenient, sometimes also can cause accident etc. because delay is clean.
Summary of the invention
The purpose of this utility model is to provide a shield glass automatic cleaning system, enables automobile automatically carry out cleaning when fine day.
For achieving the above object, the technical solution adopted in the utility model is: a daily automatic cleaning system of shield glass, is characterized in that comprising wiper assembly, sensor, light source and control circuit.
Above-mentioned wiper assembly, is characterized in that comprising Wiper blade assembly, electrical motor, retarder, four-bar linkage, Wiper blade axle and scrubber system, and is connected with controller circuitry, carry out control work by control circuit.
Above-mentioned sensor, it is characterized in that sensor is silicon photovoltaic cells, model is BPW34S, connects in control circuit, can be electric energy by the light energy conversion received from light source to a certain extent, thus controller circuitry is controlled wiper assembly.
Above-mentioned light source, it is characterized in that light source is infrarede emitting diode LED light source, model is SIR-381SB3, electric energy can be converted into infrared light and can radiate.Its installation site is above the gauge panel in chaufeur dead ahead, and chaufeur can not be seen.
Above-mentioned controller, it can control wiper assembly automatically according to the clean-up performance of glass, does not need people to be action.
Structure of the present utility model is simple, reasonable in design; Received the power of infrared light by sensor, control the work of wiper, automatically front windshield is cleaned.
Accompanying drawing explanation
Fig. 1 is control circuit;
Fig. 2 is power circuit.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, control circuit comprises resistance R1 and R2, potential device RP, sensor silicon photovoltaic cells B, forms composite amplifier, relay K, cond C by two aerotron VT1 and VT2; It is characterized in that sensor silicon photovoltaic cells can receive the light from light source, be connected by the base stage of sensor silicon photovoltaic cells with composite amplifier VT1, control conducting and the cut-off of aerotron VT1 and VT2; The collecting electrode of aerotron VT2 is connected with relay K, comes coil blackout and the charging of control relay K, then controls power circuit; The effect of electric capacity C wherein in parallel with relay suppresses high potential; The effect of potential device RP is the threshold values of adjustment aerotron VT1 conducting or cut-off, thus the sensitivity of adjustment photoelectric switch.
As shown in Figure 2, power circuit comprises windscreen wiper assembly, relay contact switch K, DC contactor KM; It is characterized in that relay contact switch K controls its opening and closing by the control circuit in Fig. 1; DC contactor KM connects with relay contact switch K, controls the closed of contact switch; Wiper assembly and control circuit access in power circuit jointly.
This device principle of work:
When on Windshield, dust is more, it is less that silicon photovoltaic cells sensor B receives the light sent from infrarede emitting diode LED light source, VT1 in control circuit Fig. 1, VT2 is all in off condition, the coil blackout of relay K, its normally closed contact connects the coil of DC contactor KM in circuit, thus is closed by the open contact of contactless switch, and rain brush assembly is started working.When cleaning clean, it is many that silicon photovoltaic cells sensor B receives the light sent from infrarede emitting diode LED light source, produces the electro-motive force of 0.2-0.5V, make aerotron VT1, VT2 conducting, finally cause DC contactor KM main contact to disconnect, Wiper system quits work.
The above; be only preferred embodiments of the present utility model, not any restriction done to the utility model, every any simple modification above example done according to the utility model technical spirit; change and equivalent structure transformation, all still belong in the scope of technical solutions of the utility model protection.
