Description
Technical field
The utility model relates to a kind of Multifunctional relay that is used for the preceding rain shaving electrical machine of Control of Automobile, belongs to automobile technical field.
Background technology
At present, rain shaving electrical machine generally is to be controlled jointly by wiper switch in the combined switch and intermittent duty relay before the automobile, all the flow through inner contact of wiper switch of the working current of each grade of rain shaving electrical machine (comprising high speed, low speed, intermittence and washing) therefore requires combined switch can carry bigger electric current.But development along with automotive electronic technology, combined switch more is to adopt the electronic switch that adhesive sound is little, loaded current is little, if still use traditional rain brush intermittent duty relay, then must increase the high, low speed control relay, and the increase of relay quantity not only can improve the manufacturing cost of automobile, but also can increase circuit bonded assembly complexity, and the hidden danger trouble point of circuit is increased, serviceability descends.
The utility model content
The purpose of this utility model is the drawback at prior art, and a kind of intelligent wiper relay that can adapt to the combined switch demand for development is provided, and with the reliability of raising automobile line, and reduces its manufacturing cost.
Problem described in the utility model realizes with following technical proposals:
A kind of intelligent wiper relay, it comprises micro controller system, Wiper Relay and rate of change relay, four input ports of described micro controller system connect the high speed contact of wiper switch respectively through four level translators, the low speed contact, the reset signal mouth of contact and rain shaving electrical machine intermittently, two output ports of micro controller system are respectively through the control coil of two non-gate control Wiper Relay and rate of change relay, the moving contact of described Wiper Relay connects the moving contact of rate of change relay, its moving break back contact that closes is just breaking break back contact difference power connection with moving, negative pole, the moving of described rate of change relay closed break back contact and moves High-speed Control line and the low speed control line that disconnected break back contact connects rain shaving electrical machine respectively.
Above-mentioned intelligent wiper relay, another input port of described micro controller system is connected with the positive wire of scrubber through another level translator.
Above-mentioned intelligent wiper relay, described level translator is made of electric capacity and two resistance, and every road incoming signal of micro controller system connects input of single chip more earlier through two electric resistance partial pressures behind electric capacity filtering radio-frequency interference.
Above-mentioned intelligent wiper relay, described micro controller system is powered by three terminal regulator, and the voltage input end of described three terminal regulator connects automobile power source.
The utility model inserts micro controller system with each road control signal of rain shaving electrical machine, after micro controller system collects these signals, by the mode of operation of two relay control rain shaving electrical machines.The utility model has been realized the Based Intelligent Control of rain shaving electrical machine, make the control circuit of wiper simple more, reliable, function is more complete, and cost is cheaper, and the do not flow through inner contact of wiper switch of the working current of rain shaving electrical machine, meet the demand for development of combined switch.
