The door-in-place normally-closed magnetic induction switch 23, the normally-open pressure sensor 4 and the magnetic induction switch 7 are sequentially connected in series and then connected between the movable contact of the rocker switch 26 and the door-opening static contact of the rocker switch 26; the moving contact of the rocker switch 26 is connected with a direct-current power supply 29, the door-to-place normally-open magnetic induction switch 24, the time-delay power-off controller 25 and the coil at the B end of the two-position three-way electromagnetic valve 20 are sequentially connected in series and then connected between the direct-current power supply 29 and the ground, and the coil at the A end of the two-position three-way electromagnetic valve 20 is connected between the door-closing static contact of the rocker switch 26 and the ground; the coil at the B end of the two-position five-way electromagnetic valve 21 is connected between the door-closing static contact of the rocker switch 26 and the ground, and the coil at the A end of the two-position five-way electromagnetic valve 21 is connected between the door-opening static contact of the rocker switch 26 and the ground; the main coil 1 is connected between the door-closing stationary contact of the rocker switch 26 and ground.
The air source 19, the rocker switch 26, the door cylinder 27 and the like in the invention all belong to the existing devices related to the door switch operation on the passenger car or the bus. The coil at the A end of the two-position three-way electromagnetic valve 20 controls an air outlet A, and the coil at the B end controls an air outlet B; the C-end coil of the two-position five-way electromagnetic valve 21 controls the air outlet C port, and the D-end coil controls the air outlet D port.
When a driver presses the rocker switch 26 to open the passenger door, the coil at the B end of the two-position three-way electromagnetic valve 20, the coil at the D end of the two-position five-way electromagnetic valve 21 and the main coil 1 of the anti-pinch control valve 28 are electrified, and at the moment, the air pressure of the air source 19 is directly led to the air inlet P of the two-position five-way electromagnetic valve 21 through the air outlet B of the two-position three-way electromagnetic valve 20 and then led to the speed-regulating throttling joint 30 of the anti-pinch control valve 28 through the air outlet D of the two-position five-way electromagnetic valve 21; then the air pressure enters the first channel 10, because the main coil 1 is connected with a power-on signal, the static iron core 2 sucks up the movable iron core 17 for a short time, the fourth channel 16 is opened to enable the air pressure at the left end of the central valve cavity 32 to carry out short-time pressure discharge through the instantaneous exhaust channel 13, at this time, the valve rod 15 is moved leftwards by the air pressure entering from the first channel 10 and under the combined action of the first spring 6, and meanwhile, the movable iron core 17 is disconnected after the magnetic switch 7 detects the magnetic force of the magnet block 14 (the magnetic switch 7 is disconnected after the magnetic switch is in a normally closed type and is energized state); the air pressure entering from the first channel 10 simultaneously enters the pressure cavity of the normally open pressure sensor 4 so as to close the normally open pressure sensor 4, enters the air inlet cavity 31 and tries to enter the air storage cavity 33 through the second channel 11, and the air pressure overcomes the resistance of the second spring 8, pushes the sealing plug 9 blocking the second channel 11 leftwards and then enters the central valve cavity 32 at the left end of the valve rod 15 through the third channel 12 for storage; the air pressure entering the air intake chamber 31 enters the open door F end of the door cylinder 27 through the air intake joint 5, the closed door E end of the door cylinder 27 is decompressed, and the passenger door is opened.
When a driver presses the rocker switch 26 to close a passenger door, the coil at the end a of the two-position three-way solenoid valve 20 and the coil at the end C of the two-position five-way solenoid valve 21 are simultaneously energized, the air pressure in the air source 19 reaches the air inlet port P of the two-position five-way solenoid valve 21 through the air outlet port a of the two-position three-way solenoid valve 20 and the pressure regulating valve 22, and then is communicated to the door closing end E of the door cylinder 27 through the air outlet port C of the two-position five-way solenoid valve 21, the air inlet port E of the door closing end and the air outlet port F of the door opening end of the door cylinder 27 are simultaneously energized, the air inlet port F of the door opening end is connected with the air inlet connector 5 of the anti-pinch control valve 28, and then the air pressure enters the first channel 10 and the pressure cavity of the pressure sensor 4 through the air inlet connector 5, so that the pressure sensor 4 is energized, and then is communicated to the two-position five-way solenoid valve 21 through the speed regulating connector 3 to exhaust, thereby driving the door to be closed. If the passenger door encounters an obstacle and the movement is blocked in the door closing process, the air pressure at the door closing end E of the door cylinder 27 is increased, the pressure value of the air pressure at the door opening end F is reduced rapidly due to the fact that a certain air pressure is stored at the left end of the central valve cavity 32 when the door is opened, the pressure value of the right end of the valve rod 15 is smaller than that of the left end at the moment, the valve rod 15 overcomes the resistance of the first spring 6 and rapidly moves towards the right end in a reversing mode under the driving of the left end pressure, the magnetic sensing switch 7 is powered on, the normally open pressure sensor 4 is powered on, the door-in-place normally closed magnetic sensing switch 23 is powered on, the D-end coil of the two-position five-way electromagnetic valve 21 is powered on, the electromagnetic valve reverses, the door cylinder 27 is changed into air inlet at the door opening end F and air outlet at the door closing end E from air inlet at the door opening end E, and the passenger door opening end is opened. If the passenger door does not encounter an obstacle in the door closing process, when the passenger door is to be closed in place, the door-in-place normally-closed magnetic induction switch 23 and the door-in-place normally-open magnetic induction switch 24 respectively detect that the anti-pinch line is disconnected after the magnet on the door is detected, the coil at the B end of the two-position three-way electromagnetic valve 20 is electrified through the delay controller 25 and is disconnected after the electrifying time is controlled to be 1S, and at the moment, the air pressure of the air source 19 directly enters the door cylinder 27 through the two-position three-way electromagnetic valve 20 without passing through the pressure regulating valve 22.
Because the air pressure of the passenger door passes through the pressure regulating valve 22 in the normal closing process, the pressure regulating valve 22 is used for regulating the air pressure supplied to the door cylinder 27 to be lower than the air pressure of the air source 19, so that the sensitivity of the anti-pinch control valve 28 is regulated and the stability of the supplied air pressure is ensured, but the closing force of the passenger door after the passenger door is closed is insufficient, when the passenger door is closed to a proper position, the air pressure of the door cylinder 27 is instantly equal to the air pressure of the air source 19 after the B end of the two-position three-way electromagnetic valve 20 is electrified, and the passenger door returns to the closing set force. When the passenger door is closed to the air pressure at the opening end F of the rear door cylinder 27 in place, the normally open pressure sensor 4 is in a disconnected state, the anti-pinch line is powered off for the second time, the normally closed magnetic induction switch 23 in place can not prevent the passenger door from being pinched and automatically opened if the door is powered on due to failure, and the anti-pinch is automatically cancelled when the air pressure of the door cylinder 27 is reduced to be lower than 0.5 MPa.
The other function of the door-in-place normally-closed magnetic induction switch 23 is as follows: if the passenger door is not closed in place, the anti-pinch circuit cannot be disconnected, and the vehicle door cannot be closed, so that whether the passenger door is closed in place or not is detected.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
