Summary of the invention
In order to solve the defect that above-mentioned prior art exists, the utility model provides a kind of novel power window clamp prevention protective device, and defencive function reaction is fast, and vehicle window will be stopped and decline of reversing when not encountering obstruction.
The utility model realizes with following technical scheme: a kind of new automobile power window clamp prevention protective device, comprises one for controlling the executing agency that vehicle window rises or declines, to the control circuit of executing agency's transmit button signal, described control circuit comprises light emitting diode D1, phototriode V1, voltage comparator A1, resistance R1, R2, R3, R4, R5 and relay K A, triode V2 and Car window electric machine M, one end of the positive pole contact resistance R1 of light emitting diode D1, the minus earth of light emitting diode D1, one end of the other end of resistance R1, one end of resistance R2, resistance R3 and a termination positive source of resistance R5, the colelctor electrode of another termination phototriode V1 of resistance R2 and the negative input end of voltage comparator A1, one end of other end connecting resistance R4 of resistance R3 and the positive input terminal of voltage comparator A1, the other end ground connection of resistance R4, the output of another termination voltage comparator A1 of resistance R5, one end of relay K A and the base stage of triode V2, the other end ground connection of relay K A, the colelctor electrode of triode V2 is connected with the positive pole of motor M operating voltage Vo, the colelctor electrode of triode V2 connects one end of Car window electric machine M simultaneously by a constant close contact ground connection of relay K A, Car window electric machine M is by a constant open contact ground connection of relay K A, the colelctor electrode of triode V2 connects the other end of Car window electric machine M by another constant close contact of relay K A, light emitting diode D1 is arranged on the side of vehicle window, phototriode V1 correspondence is arranged on the opposite side of vehicle window, the base stage of phototriode V1 is for receiving visible ray or the infrared rays of light emitting diode D1 transmitting.
The beneficial effects of the utility model: if when power windows rises, the words of obstruction are had between vehicle window and vehicle window top, power windows can stop rising at once, then automatically decline, thus prevent the nipped situation of passenger, owing to being employing photoelectric sensor, the human body made or obstruction are without the need to contacting with vehicle window, vehicle window just can be made to stop and declining, thus improve safety, completely eliminating passenger may by what crush; Cost is low, may be used for the anti-pinch protection of automobile electric car-window.
Accompanying drawing explanation
Fig. 1 is the utility model theory diagram;
Fig. 2 is this control circuit figure.
Detailed description of the invention
As shown in Figure 1, a kind of new automobile power window clamp prevention protective device, the emitter of photoelectric sensor is installed in the side of vehicle window, the receiving system of photoelectric sensor is installed at the opposite side of vehicle window, wherein emitter adopts light emitting diode, receiving system adopts phototriode, light emitting diode launches infrared rays or visible ray to phototriode, in vehicle window uphill process, if there is obstruction to enter between vehicle window and window top, the acceptance of receiving system pipeline can be hindered, then receiving system can send switching signal to executing agency, executing agency can control, and vehicle window can stop before this, then automatically decline, passenger is prevented to be occurred by situation about crushing.
As shown in Figure 2: control circuit comprises light emitting diode D1, phototriode V1, voltage comparator A1, resistance R1, R2, R3, R4, R5 and relay K A, triode V2 and Car window electric machine M.
Light emitting diode D1 and R1 is connected, phototriode V1 and R2 is connected, phototriode V1 is also connected with the negative pole of voltage comparator A1, R3 and R4 is connected, R3 and R4 is also connected with the positive pole of voltage comparator A1, resistance R5 is connected with relay K A, and resistance R5 is also connected with the output of voltage comparator A1, and voltage comparator A1, resistance R5 are connected with the base stage of triode V2 with relay K A; The emitter stage of triode V2 is connected with negative pole by the constant close contact 2a of relay K A; The emitter stage of triode V2 is connected with Car window electric machine M; Car window electric machine M is connected with negative pole by the constant open contact 3a of relay K A; Voltage comparator adopts LM399; Voltage comparator is connected with supply voltage VCC positive pole;
The colelctor electrode of triode V2 is connected with the positive pole of motor operating voltage Vo; Car window electric machine M is connected with the positive pole of Vo by relay constant close contact.
The course of work: when vehicle window rises and do not have barrier obstruction between light emitting diode D1 and phototriode V1, phototriode V1 conducting, the cathode voltage of voltage comparator A1 is higher than cathode voltage, so voltage comparator output HIGH voltage, triode V2 conducting, relay K A coil obtains electric, and the constant open contact 3a of relay K A coil obtains electric closed, and Car window electric machine obtains electric drive vehicle window and rises;
Vehicle window rise process as, if have barrier obstruction between light emitting diode D1 and phototriode V1, photodiode V1 does not receive the light that light emitting diode D1 occurs, so phototriode cut-off, the cathode voltage of voltage comparator A1 is lower than cathode voltage, so voltage comparator does not have high voltage to export, triode V2 ends, Car window electric machine M dead electricity stops rising, relay K A coil losing electricity, constant close contact 1a and 2a of relay K A closes, the both positive and negative polarity of Car window electric machine M is put upside down electric, Car window electric machine M starts to obtain electric decline, the constant open contact 3a of relay K A disconnects simultaneously, disconnect the rising circuit of Car window electric machine.
