Detailed description of the invention
Below by detailed description of the invention, the technical solution of the utility model is described in further detail.
Embodiment 1
Referring to Fig. 1, Fig. 2, Fig. 3, the utility model clamp prevention controller of closing the door, comprise power circuit, open, the driving circuit for electromagnetic valve of closing the door, courtesy lamps circuit, anti-pinch control circuit, described anti-pinch control circuit adopt air bag switch series be connected to the driving circuit for electromagnetic valve of closing the door latching circuit output dry contact and open the door between driving circuit for electromagnetic valve, the open the door power supply of driving circuit for electromagnetic valve of connection, its difference from prior art is: described courtesy lamps circuit adopts relay K 1 to control power end by triode Q1, draw courtesy lamps power supply output signal from described relay K 1, the coil of described relay K 1 is connected in series in the output loop of triode Q1, the base stage of triode Q1 is connected with Zener diode D2, described Zener diode D2 is by the car door travel switch of current-limiting resistance R1 connecting valve door driving circuit for electromagnetic valve, the stroke switching signal state judgement of car door position is used the state judgement of the on state characteristic alternative program of triode, use the self-locking judgement of the latching circuit alternative program of relay formation.
The latching circuit of the described driving circuit for electromagnetic valve of closing the door, is mainly made up of relay K 2, relay K 3. Relay K 2 coil power supply ends are connected with relay K 3, relay K 2 normally opened contacts, relay K 2 common ports are connected with relay K 3 common ports, after door close button is pressed, K3 coil obtains electric, normally opened contact closure, simultaneously K2 relay coil obtains electricly, and normally opened contact adhesive, forms the latching circuit of the driving circuit for electromagnetic valve of closing the door.
Car door has the upper and lower car door of passenger in opening, and needs illumination, and the output of courtesy lamps power supply is controlled break-make by relay K 1 by triode Q1, and therefore, the control base stage of triode Q1 connects car door travel switch so that driving to be provided. Its operation principle is: if travel switch provides 24V signal, illustrate that car door is in closed condition, triode Q1 base stage is high level, not conducting, and relay K 1 does not respond. If instead travel switch provides low level, think car door opening, now triode Q1 base stage is low level, conducting is that relay K 1 is powered, normally opened contact adhesive, courtesy lamps obtains electric.
Because the inside such as magnetic stroke switch, adhesive tape is frame for movement, for preventing that it from causing contact contact in Vehicle Driving Cycle process because jolting, need to increase latching circuit, make it only in the time that closing of the door button is pressed, form self-locking, follow-up anti-pinch control circuit could obtain electric work. There is latching circuit, prevent that in driving, mechanical part misoperation initiation is opened the door.

Vehicle speed sensor signal accesses the base stage of triode Q3 in switch gate driving circuit for electromagnetic valve by resistance R 5, then controls triode Q2 base stage by triode Q3; The state judgement of GES is used the state judgement of the on state characteristic alternative program of triode. If the speed of a motor vehicle provides high level signal, illustrate that the speed of a motor vehicle is not more than 5KM/H, now triode Q3 conducting, triode Q2 conducting, diode D12 obtains electric; Otherwise diode D12 can not obtain electric. Guarantee car starts can not opened automatically with tail gate.
The utility model clamp prevention controller of closing the door, open and close door driving circuit for electromagnetic valve uses dpdt relay, controls the VDD-to-VSS of magnetic valve, ensures that in cutting off, not having inverse electromotive force feeds back in power supply by ground wire.
In switch gate driving circuit for electromagnetic valve, relay R LY1 is connected with pass gate signal, presses door close button, and relay R LY1 adhesive, provides pass gate signal. Relay R LY2 is connected with diode D12, if clamp people in the time closing the door, anti-pinch enables effectively simultaneously, and the speed of a motor vehicle is not more than 5KM/H, now relay R LY2 adhesive, and normally opened contact closure, the magnetic valve that opens the door obtains electric.
Embodiment 3
Referring to Fig. 1, Fig. 2, Fig. 3, the clamp prevention controller of closing the door of the present embodiment, different from aforementioned each embodiment 1, in described power circuit, use high-power TVS to suppress supply voltage; For preventing that load from existing short trouble, increase by one from recovering insurance R0 simultaneously, make it the in the situation that of load short circuits, can disconnect the connection of clamp prevention controller and power supply; Then high-power transient voltage twin zener dioder D3 in parallel, to absorb the transient voltage on power supply, then seals in diode D11, prevents reverse power supply protection.
Power supply accesses this device by vehicle body, and according to environment for use, because vehicle electronics exists a large amount of moment electromotive force, therefore power circuit need to use high-power TVS(transient voltage twin zener dioder) supply voltage is suppressed; For preventing that load from existing short trouble, increase by one and make its connection that can disconnect clamp prevention controller and power supply in the situation that of load short circuits from recovering insurance R0 simultaneously, prevent that short circuit from affecting higher level's power generation. Then high-power transient voltage twin zener dioder D3 in parallel, can absorb the transient voltage on power supply, then seal in diode D11, prevents reverse power supply protection. Power circuit accesses this device after handling.

As shown in the figure, according to the description of embodiment 1, relay K 1 is powered, normally opened contact adhesive, and courtesy lamps obtains the electric while, and the common port contact of relay K 2, K3 obtains electric. Like this, after door close button is pressed, K3 coil obtains electric, normally opened contact closure, and while K2 relay coil obtains electric, and normally opened contact adhesive forms latching circuit, and air bag sensor SEN_1# obtains electric.
Because air bag sensor is connected with anti-pinch enable switch S1, air bag sensor SEN_1# obtains electric, if clamp people, SEN_1# and SEN_2# conducting, enable in effective situation in anti-pinch, triode Q2 simultaneously electric.
After the clamp prevention controller of closing the door powers on, press rocker switch door button, corresponding switch gate magnetic valve action. In magnetic switch situation not in place, press door close button, latching circuit self-locking, follow-up air bag switch obtains electric, and if there is people to be pressed against, air bag switch provides level signal, and GES provides current state simultaneously, and if automobile does not travel, car door is opened automatically.
The utility model clamp prevention controller of closing the door, operation principle is as described below:
The action of opening the door:
1) press door open button, relay R LY2 obtains electric adhesive, the adhesive of RLY2 normally opened contact, and output voltage drives the magnetic valve that opens the door;
2) car door opening, car door travel switch provides low level, triode Q1 conducting, relay K 1 obtains electric, the adhesive of K1 normally opened contact, courtesy lamps is lighted;
The action of closing the door:
1) now car door in open mode, travel switch output low level, triode Q1 conducting, relay K 1 electric, the adhesive of K1 normally opened contact;
2) press door close button, relay R LY1 obtains electric adhesive, the adhesive of RLY1 normally opened contact, and output voltage drives the magnetic valve of closing the door; Simultaneously relay K 3 coils obtain electric, the adhesive of K3 normally opened contact, then K2 coil obtains electricly, the adhesive of K2 normally opened contact, forms latching circuit;
3) now air bag switch dry contact obtains electricly, if push passenger when closing of the door, the normal switching of air bag switch closed, and triode Q2 obtains electric;
4) if now the speed of a motor vehicle is less than 5KM/H, GES provides high level, triode conducting, and relay R LY2 adhesive, the normal switching of RLY2 closed, and output voltage drives the magnetic valve that opens the door;
5) car door opening.
