Describe the utility model in detail below in conjunction with embodiment.
Embodiment one
In Fig. 2: direction switch K is a double-pole double-throw coordinated type power switch; R1 is for rising/descend shared sample resistance; R10 is for returning the bottom sample resistance; SCR2 is the control controllable silicon that rises; SCR1 is the control controllable silicon that descends; SCR4 is that anti-pinch is returned the control controllable silicon; SCR3 is that anti-pinch is returned bottom outage control controllable silicon, and J1 is for rising/descend shared control relay, with two pairs of constant close contacts and a pair of constant open contact; J2 is that anti-pinch is returned control relay, with two pairs of constant open contacts; J3 is that anti-pinch is returned bottom outage control relay, uses a pair of constant close contact; R2 is an anti-pinch power regulator potentiometer; R6, R11 are rotation-clogging protection electric current regulator potentiometer; G is that dry reed switch is blocked in the place of safety, and its magnet is installed on the lifting glass for vehicle window arm, and with the lifting arm lifting, its switch is fixedly mounted on the lifting arm stroke, apart from the about 4mm of vehicle window top dead-centre place; C1～C4 is a delay capacitor; D1, D7, Z1, Z2 are fly-wheel diode; D2～D6 is the reverse isolation diode; The PNP triode is as phase inverter.
Its course of work is as follows:
When direction switch K placed " rising " position, supply voltage was added on the lifting motor M by two pairs of constant close contacts of sample resistance R1 and J1, and motor M drives upwards operation of glass, and sample resistance constantly detects current of electric.When object was clamped (or mechanical jam occurring) by glass for vehicle window, the glass run resistance strengthened, and the motor M electric current also and then strengthens.When obstacle (resistance) reaches the anti-pinch power of setting, sampling voltage drives the conducting of PNP triode, the output voltage of its colelctor electrode carries out dividing potential drop through behind the D3 by R3, R4, dividing potential drop on the R4 directly triggers controllable silicon SCR 2 through R5, relay J 1 conducting, two pairs of constant close contacts of J1 disconnect lifting motor M, and glass is out of service.The a pair of constant open contact of J1 is connected simultaneously, carries out dividing potential drop by R7, R8 behind the constant open contact of supply voltage process J1 and the D6, and the dividing potential drop of R8 directly triggers controllable silicon SCR 4 through R9, the J2 conducting, two pairs of constant open contact control motor M inverted runnings of J2 discharge clipped object, and R10 detects current of electric simultaneously.If inverted running is to bottom dead centre and stall for motor M always, when locked rotor current reached setting value, the sampling voltage on the R10 triggered controllable silicon SCR 3; the J3 action; its constant close contact disconnects relay J 2, and two pairs of constant open contacts of J2 disconnect lifting motor M, thereby motor M is protected.
If not having object in the glass for vehicle window uphill process is clamped, mechanical jam does not appear yet, when running to from top dead-centre 4mm place, dry reed switch G closure, the control utmost point of SCR4 is blocked in advance, and when glass run during to top dead-centre and stall, the sampling voltage on the R1 triggers controllable silicon SCR 2 by the PNP triode, the J1 action, two constant close contact disconnects lifting motor M.This has just finished normal pass closed procedure.
Glass rising resistance surpasses setting value two kinds of situations: (1) has clamped object or mechanical jam midway; (2) glass is normally closed and has been raised to upper dead center position.Glass arrives top dead-centre will produce inverse signal equally, will move downwards, and this is wrong at once.Owing to be provided with dry reed switch G, when lifting arm arrival before top dead center, dry reed switch G closure is blocked the motor reverse turn control circuit in advance, just can not return just outage shutdown when glass arrives top dead-centre.This has just realized that " have thing to be pressed from both sides, glass for vehicle window returns; Normally be closed to top dead-centre, glass for vehicle window does not return ".
When direction switch K placed " decline " position, supply voltage oppositely was added on the lifting motor M through two constant close contacts and the sample resistance R1 of direction switch K, J1, and motor M drives glass and moves downwards.As do not have the jam phenomenon, and motor M can run to bottom dead centre and stall always, and when locked rotor current reached setting value, the sampling voltage on the R1 directly triggered controllable silicon SCR 1, the J1 action, its constant close contact disconnects lifting motor M.This has just finished the process of opening the door normally.
As jam occurs and stall in the decline process, the sampling voltage on the R1 can directly trigger controllable silicon SCR 1 equally, the J1 action, and its constant close contact disconnects lifting motor M, and the protection motor M is not damaged.
Embodiment two
In Fig. 3: direction switch K is the single-pole double throw touch switch; R is " rising/decline/anti-pinch is returned/stall " shared sample resistance; T1 is the control triode that rises; T2 is the control triode that descends; SCR1 controls shared controllable silicon for " outage/anti-pinch that rises outage/anti-pinch is returned "; SCR2 controls shared controllable silicon for " outage/anti-pinch that descends is returned outage "; J1 is the rising control relay, with two pairs of constant open contacts; J2 controls shared relay for " decline/anti-pinch is returned ", with two pairs of constant open contacts; J3 is an anti-pinch inverse signal relay, uses a pair of constant open contact; R4 is an anti-pinch power regulator potentiometer; R5 is a decline locked rotor current regulator potentiometer; Z1 and Z2 are the thresholding voltage-reference diode; D1, D4, D6 are fly-wheel diode; D3 is the reverse isolation diode; D2, D5 are discharge diode; C1～C4 is a delay capacitor.
When direction switch K places " rising " position, carry out dividing potential drop by resistance R 1 and R2 behind the supply voltage process direction switch K, the voltage that dividing point A is ordered drives triode T1 saturation conduction through R3 and Z1, relay J 1 closure, supply voltage is added on the lifting motor M through its two pairs of constant open contacts and sample resistance R, driven by motor glass is operation upwards, detects current of electric by sample resistance simultaneously.When object was clamped, the glass run resistance strengthened, and current of electric also strengthens, when running resistance reached the anti-pinch power of setting, the voltage triggered controllable silicon SCR 1 on the sample resistance R was moved A point current potential below the threshold voltage of Z1 to by force, T1 ends, the J1 outage, and glass stops up.Simultaneously, after the SCR1 conducting, relay J 3 is also connected, supply voltage carries out dividing potential drop through behind the closing contact of J3 by R6 and R7, the voltage that dividing point C is ordered drives triode T2 saturation conduction through R8 and Z2, relay J 2 closures, and supply voltage oppositely is added on the motor M through closing contact and the sample resistance R of J2, motor M drives glass and moves downwards, to discharge clipped object.When glass arrives bottom dead centre and stall, when locked rotor current reached setting value, sampling voltage triggered controllable silicon SCR 2, by force C point current potential was moved to below the threshold value of Z2, and T2 ends, the J2 outage, and lifting motor M also cuts off the power supply.This has just finished the control procedure of " anti-pinch-return-cut off the power supply ".
If not having object in the glass uphill process is clamped, when running to from top dead-centre 4mm place, dry reed switch G closure, the base stage of T2 is blocked in advance, and when glass run during to top dead-centre and stall, the sampling voltage on the R triggers controllable silicon SCR 1, by force A point current potential is moved to below the threshold value of Z1, T1 ends, the J1 outage, and lifting motor also cuts off the power supply.This has just finished normal pass closed procedure.
When direction switch K places " decline " position, supply voltage process direction switch K is by R6 and R7 dividing potential drop, the current potential that dividing point C is ordered drives triode T2 saturation conduction, relay J 2 closures, supply voltage oppositely is added on the lifting motor M by closing contact and the sample resistance of J2, and motor M drives glass and moves downwards.As do not have the jam phenomenon, motor M can run to bottom dead centre and stall always, when locked rotor current reaches setting value, sampling voltage on the R triggers controllable silicon SCR 2 conductings, and C point current potential is pulled to below the threshold value of Z2 by force, and T2 ends, the J2 outage, lifting motor M also cuts off the power supply.This has just finished normal opening process.
As jam occurs and stall in the decline process, the sampling voltage on the R can trigger controllable silicon SCR 2 conductings equally, forces J2 to disconnect, lifting motor M outage, thus motor M is protected.
