Description
Technical field
The utility model relates to the car electrics control setup, and particularly a kind of speed of a motor vehicle is regulated wiper controller.
Background technology
The windscreen wiper of shield glass window is removed the rainwater on the glass port in the time of can travelling in the automobile rainy day, being convenient to the driver has the visual field clearly, is the indispensable device of guaranteeing safety traffic.Wiper controller on the automobile has two kinds at present: a kind of is the combined switch of physical construction, switch the load current of rain shaving electrical machine, the power of motor is between 60W～120W, so when the control windscreen wiper such as scrapes, scrapes slowly, stops soon at operation, switch current on the switch reaches more than the 10A, switch pole is easy to wear even burn out, and this combined switch cost is very high, maintenance and change also very trouble; Another kind is by the control circuit (as shown in Figure 1) of setting program, relay conversion, can scrape soon, scrapes slowly, intermittently scrapes, the cleaning scraper operation, and the light and handy diverse in function of structure is reliable, has overcome the existing problem of physical construction.But its weak point is an intermittent time is to fix, and generally between 4～6 seconds, and speed of a motor vehicle faster or slower, rainfall varies, the slow or rainfall hour in the speed of a motor vehicle, and intermittent time is too short, and rain brush too much rocks and can make the driver feel dizzy; When fast or rainfall was big in the speed of a motor vehicle, intermittent time was oversize, and the residue rainwater is observed the fuzzy and influence of glass.
Summary of the invention
The utility model is fragile in order to solve existing wiper controller, intermittently scrapes the single existing technical matters of control, and develops the wiper controller of a kind of setting program, speed of a motor vehicle adjusting.
According to above-mentioned purpose, the utility model provides a kind of speed of a motor vehicle to regulate wiper controller, comprises microcomputer MCU, first relay J 1, second relay J 2, aerotron T, power supply E, also comprises speed of a motor vehicle sample circuit, intermittent time initialization circuit; Wherein speed of a motor vehicle sample circuit comprises diode D, first resistor R 1, second resistor R 2; First resistor R 1 is connected the back and is connected with 8 ends of microcomputer MCU with second resistor R 2, the other end of first resistor R 1 is connected with diode D is anodal, and the other end of second resistor R 2 is connected with power supply E is anodal; Diode D negative pole is connected with vehicle speed signal V; Wherein the intermittent time initialization circuit comprises the 3rd resistor R 3, the 4th resistor R 4, external step resistance R5～R8, K switch are connected with setting signal Pot, the 3rd resistor R 3 is connected the back and captives joint with K switch with the 4th resistor R 4, the other end of the 3rd resistor R 3 is connected with power supply E is anodal, the other end of the 4th resistor R 4 is connected with 6 ends of microcomputer MCU, the other end ground connection GND of step resistance R5～R8.
The utility model is owing to taked above technical measures, and it is light and handy to have structure, easy to maintenance, reliable advantage.Especially the intermittent time stepping is set and speed of a motor vehicle auto-adjusting circuit, guarantees that automobile can both guarantee that at heavy rain, when running at high speed front screen has the visual field clearly, has improved the traveling comfort and the traveling security of navigating mate.
Description of drawings
Fig. 1 is the circuit diagram of existing wiper controller.
Fig. 2 is a circuit diagram of the present utility model.
Fig. 3 is intermittent time of the present utility model and speed of a motor vehicle diagram of curves.
The specific embodiment
As shown in Figure 2, be a kind of setting program, the wiper controller circuit diagram regulated with the speed of a motor vehicle.In microcomputer MCU, extension blows and intermittently scrape the operating sequence of action to store scraping soon, scrape slowly, cleaning of weaving, microcomputer MCU in service accepts operating knob 53b, 53,53c and the I signal of exercises, give relay through judging the output control signal corresponding, relay is by the connection mode of the closure state conversion control circuit of contact, and the corresponding driving electric current is defeated by the armature loop of motor, motor drives windscreen wiper system again and makes corresponding action.
The utility model has increased intermittent time setting and two circuit of speed of a motor vehicle sampling to intermittently scraping I, below contrast is further elaborated.
Press and intermittently scrape the I operating knob, microcomputer MCU collects mail number and starts the program of intermittently scraping through judging by 14 terminations, again by the output of 9 ends intermittently high level give aerotron T, aerotron T conducting makes 1 adhesive of first relay J, the closed energized E of contact J11.And second relay J 2 does not have adhesive, and contact J22 opens with armature loop slow-speed end St1 and is connected, and then motor slow-speed (is turned around and stopped several seconds, go round and begin again.), do intermittently to scrape thereby drive rain brush.
The utility model also can select K switch position in the intermittent time initialization circuit with setting signal Pot (the branch fourth gear is an example) by the driver, automatically vehicle speed signal is imported 6,8 ends of microcomputer MCU respectively by speed of a motor vehicle sample circuit, scraped action the intermittence of controlling windscreen wiper by setup program.
The resistance value of divider resistance R5～R8 in the intermittent time initialization circuit is different, and the terminal voltage value of then importing microcomputer MCU8 also is different, to identify different gears.
For example: in the intermittence initialization circuit K switch at the 1st grade (R5=3K), R3=18K, E=12V, then 8 terminal voltage values are V5=E* (R5/R5+R3)=12* (3/3+10)=1.7143V.
For example: in the intermittence initialization circuit K switch at the 4th grade (R8=8K), R3=18K, E=12V, then 8 terminal voltage values are V8=E* (R8/R8+R3)=12* (8/8+18)=3.6923V.
Be the diagram of curves of intermittent time of the present utility model and speed of a motor vehicle relation as shown in Figure 3.Divide the four-speed initialization circuit according to intermittent time, 6 ends of four magnitudes of voltage input microcomputer MCU are arranged, each magnitude of voltage is imported vehicle speed signal 8 ends of microcomputer MCU automatically at speed of a motor vehicle sample circuit, can form four curve S TEP1～4.
For example: the speed of a motor vehicle is 100 kilometers/hour, can find from diagram of curves, and the intermittent time of selecting the 1st grade is about 14 seconds, is suitable for light rain; The intermittent time of selecting the 4th grade is about 2.5 seconds, is suitable for heavy rain.Rainfall greatly then intermittent time is short.
For example: when selecting the 1st grade, the speed of a motor vehicle is 50 kilometers/hour, and intermittent time is about 16 seconds; The speed of a motor vehicle is 150 kilometers/hour, and intermittent time is about 12.5 seconds.Then intermittent time is short soon for the speed of a motor vehicle.
