Definitions

  • the invention relates to an electropneumatic door drive in vehicles for the transportation of people, in particular for swing doors of buses, with the features from the preamble of patent claim 1.
  • the reversing valve used in these door drives is designed so that when an emergency signal is emitted from the emergency release device, for example by actuating an emergency valve, the pistons of the pneumatic drive cylinder are acted upon by compressed air from both sides.
  • the drive device does not end up in an unpressurized state, but only in an inactive state in which the vehicle door is in Principle can be opened by hand.
  • the object underlying the invention was to provide an electropneumatic door drive with the features from the preamble of claim 1 so that after actuation of the emergency release device when trying to open the door by hand, a signal that triggers the opening movement of the door is generated.
  • the basic principle of the invention is to provide an emergency control device which is only effective when the emergency release device, for example an emergency valve, is actuated and which then supplies a signal to the reversing valve from the opening switch arranged in the region of the door or the door drive in order to achieve the Valve position in which the opening movement of the door side of the piston of the Compressed air is applied to the drive cylinder.
  • the essential component of this emergency control device is a bistable relay which controls the supply of the control signals for the reversing valve via a relay contact which can assume two positions, hereinafter referred to as "OPEN" and "CLOSE" will.
  • This bistable relay has two control inputs.
  • the first control input is designed as a so-called T input, ie a change in state of the switching position of the relay contact is achieved each time the control signal at the input changes from the value logic "0" to the value logic "1", the return of the control signal to the value " 0 "has not yet caused a change of state.
  • This T input is connected to the driver-operated switch or button for opening and closing the door via an inverter.
  • a second control input of the bistable relay is designed as a so-called S input, that is to say as an input in which a control signal with the value "0" defines a set state which has a very specific position of the relay contact, in the present case the "OPEN" position Consequence.
  • This S input is connected to the emergency switch, the actuation of which sets the relay contact to the "OPEN" position under all circumstances.
  • another relay contact closes, which establishes the connection to the opening switch located in the area of the door or door operator, via which a control signal is emitted when an attempt is made to open the door manually, which is sent directly to the corresponding input via the two relay contacts of the reversing valve is supplied so that the opening movement of the door is triggered.
  • the circuit has the property of a safety circuit, which means that the opening switch can never trigger a closing movement of the door.
  • the actuation of the emergency switch puts the emergency control device in a standby state, while the actual triggering of the opening movement then takes place from the opening switch.
  • the emergency switch can be coupled directly to the switching device known per se, for example an emergency tap, with which the door is switched without power from the emergency unlocking device.
  • the opening switch the closing of which triggers the actual opening movement of the door
  • a known pressure wave switch can be used here, as is known for the anti-trap devices on vehicle doors, which is arranged in a so-called "sensing edge" on the door.
  • an opening switch can be used which closes when such a lifting movement occurs.
  • the opening switch can also be designed so that it responds to a slight opening movement of the door, wherein it is expedient to ensure in terms of circuitry that this response can only take place when the door is inactive.
  • the drawing shows a circuit diagram of an embodiment of an electropneumatic door drive with an emergency control device for triggering an opening movement of the door, for example for the outer swing door of a bus.
  • the representation corresponds to the switching state "door open”.
  • the door movement is brought about by a pneumatic drive cylinder 3, in the supply circuit of which is provided from a compressed air source 1 and the two branch lines 1.2 and 1.3, an electrically and pneumatically controllable reversing valve 2 of a known type is arranged.
  • This reversing valve 2 can assume a total of three valve positions. In a first valve position shown in FIG. 1, one side of the piston 3.3 is acted upon via the line 1.2 and the input 3.1 of the drive cylinder, which leads to a closing movement of the door. As explained in more detail below, this valve position is achieved by electrical control of the control input 2.1.
  • the reversing valve 2 When the control input 2.2 is electrically actuated, the reversing valve 2 is switched into a valve position in which the line 1.3 and the input 3.2 on the Drive cylinder is applied to the other side of the piston 3.3, which leads to an opening movement of the door.
  • the valve can also be brought into a valve position in which both sides of the piston 3.3 are acted on via the lines 1.2 and 1.3 and the inputs 3.1 and 3.2. In this position, the piston is in a state that is not depressurized but has no power.
  • control input 2.3 is actuated pneumatically via a supply line 1.4 coming from the compressed air source 1, in which an emergency valve 4 is arranged.
  • the emergency valve 4 is actuated, the piston 3.3 is therefore switched off.
  • Resetting the reversing valve 2 to the "CLOSED" or “OPEN” state is not possible via the control input 2.3, but only by means of electrical signals via the control inputs 2.1 and 2.2.
  • the bistable relay 5 has a supply input 5.5, which is connected to a voltage source SP via a voltage adjustment circuit 7 and a reverse polarity protection diode D.
  • the input 5.6 of relay 5 is connected to ground.
  • Relay 5 has two control inputs.
  • a first control input 5.3 is designed as a so-called T input.
  • this input is coupled to the output of the circuit 7 via a "pull-up" resistor R2 and, on the other hand, is connected to the voltage source SP via an inverting element 8, a switching device S6 explained in more detail below and the button S1 which can be actuated by the driver.
  • the design of the input 5.3 as a T input has the result that when control pulses are supplied to this input by means of the pushbutton S1, the bistable relay is set back and forth, so that the relay contact 5.1 continuously moves to the "CLOSED" position (in FIG 1 shown) or "OPEN” is set.
  • the control signals leading to the reversing valve 2 are then fed from the voltage source SP via supply lines 6.1 and 6 to the relay contact 5.1.
  • the second control input 5.4 of the relay 5 is designed as a so-called S input.
  • This input is coupled to the output of circuit 7 via a "pull-up" resistor R1 and can also be connected to ground via an emergency switch S3.
  • the formation of the input 5.4 as an S input has the effect that, when the emergency switch S3 is closed, a continuous signal arrives at this input, which causes the first relay contact 5.1 to be set to the "OPEN" position.
  • a second relay contact 5.2 closes in this position, which connects the voltage supply line 6 leading to the first relay contact 5.1 via a further supply line 6.2, an opening switch S2 and an additional limit switch S4 to the voltage source SP.
  • the opening switch S2 is designed as a limit switch and can be coupled to the door drive approximately in such a way that it opens a lifting movement of the rotary column DR closes and in this way connects the control input 2.2 of the reversing valve 2 to the voltage source SP via the relay contacts 5.1 and 5.2 and the additional limit switch S4 which closes when the door opens. Due to this connection, the opening movement of the door is initiated.
  • the opening switch S2 closes when a violent opening movement is exerted on the door by hand, which leads to a lifting movement of the rotating column DR.
  • the prerequisite for this is that the emergency valve 4 was previously operated in such a way that the reversing valve 2 is in the position in which the piston 3.3 is in the de-energized state, in which the rotary column DR is lowered due to the pressure compensation and the emergency switch S3 was briefly closed .
  • the opening switch S2 can also be designed as a pressure wave switch and arranged on a sensing edge of the door.
  • the emergency switch S3 is mechanically coupled to the emergency valve 4. This can be done, for example, in such a way that actuation of the emergency switch S3 is triggered when the emergency valve 4 is brought into the alarm position in which the control input 2.3 of the reversing valve 2 is activated. The emergency valve 4 is then automatically returned to the neutral position, so that the opening movement of the door is initiated via the control input 2.2 of the reversing valve 2 when the opening switch S2 is closed.
  • the emergency switch S3 can also be located in a circuit device by means of which the Control input 2.3 of the reversing valve 2 supplied signal is generated electrically.
  • the switching element S6 switched on between the button S1 and the inverting element 8 is part of a device which prevents the door from being opened by the driver if the speed of the vehicle is still above a predetermined limit value, for example 5 km / h.
  • the switching element S6 is connected to a control device 9.1, which contains a sensor 9.2 sensing the vehicle speed. Switching element S6 opens above the specified vehicle speed and the door cannot be opened.
  • a second safety device has a switch S7, via which the control input 5.4 of the relay 5 can be connected to ground and thus receives a control signal by means of which the relay contact 5.1 is switched to the "open" position.
  • the switch S7 is controlled by a pressure sensor 10, which senses the pressure in the compressed air line 1.1. The switch S7 closes when this pressure drops below a predetermined value, thereby preventing undefined conditions from occurring.
  • the opening switch S2 can also be designed as a limit switch, which responds when the door can be opened manually by a gap of a predetermined width. In such a case, however, it turned out to be Appropriately proven if the opening switch is in a circuit that can only be activated when the drive is in the above-mentioned powerless state.
