Description

Description: TECHNICAL FIELD The present invention relates to an automobile automatic door apparatus used for buses and the like.

(Prior Art) As a conventional automobile automatic door device, for example,
The one shown in the figure is known.

This automobile automatic door device is an ignition key switch 01 provided on a vehicle (not shown), and an open / close switch 0 connected to the ignition key switch 01 and having an open position 021 and a closed position 022.
2, an open valve solenoid 04 and a close valve solenoid 05 that open and close the door opening and closing device 03 in conjunction with the operation of the open / close switch 02, and both valve solenoids 04, 0
5 and a door opening / closing switch 02, an actuator drive circuit 06, a door 07 connected to the door opening / closing device, and an emergency switch 08 for manually opening / closing the door 07 in an emergency. It was prepared.

Therefore, after closing the ignition key switch 01, the opening / closing switch 02 can be operated to open / close the door 07. When the ignition key switch 01 is opened or the emergency switch 08 is opened, both valve solenoids 04 and 05 are de-energized, so the valve pushed by the solenoid returns by the spring, and the air in the door drive cylinder 09 (hydraulic pressure When is oil)
However, the exit door could be opened and closed manually.

(Problems to be Solved by the Invention) However, such a conventional automobile automatic door apparatus has the following problems.

For example, when the door 07 is opened and closed manually after opening the ignition key switch 01, the emergency switch 08
And manually open the door 07 and open the ignition key switch 01, the ignition key switch 01 is opened, the open / close switch 02 is in the closed position 022, and the door 07 is opened. In such a state, if the driver closes the ignition key switch 01 to start the engine, the door 07 may be suddenly closed and driven.

On the contrary, the ignition key switch 01
Is opened and the open / close switch 02 is in the open position 02.
1, and when the door 07 is closed,
The door 07 was driven to be opened at the same time when the ignition key switch 01 was closed.

Therefore, when the position position of the open / close switch and the open / closed state of the door are different, the following needs to be done.

That is, match the position of the open / close switch to the open / closed state of the door, or vice versa, check the presence / absence of obstacles around the door and the safety, and then close the ignition key switch. Open or close the door, or close the ignition key switch when opening and closing the emergency switch 08, and then close the emergency switch 08 while ensuring the presence of obstacles around the door and safety. Check operation is required.

However, it is difficult for the driver to notice the inconsistency of the open / closed state of the open / close switch and the door, and the door may be driven to open / close regardless of the driver's intention. There is a risk that it may fall off or objects that lean against the door may fall.

(Means for Solving Problems) The present invention is intended to solve the above-mentioned problems, and as a means for achieving the object, the present invention provides a door opening / closing connected to a door. An actuator for driving the device is provided, a door opening / closing switch connected to an electric power source and connected to an ignition key switch that is closed by a key operation at engine start is provided, and the door opening / closing switch is provided between the actuator and the door opening / closing switch. An actuator drive circuit is provided which drives the actuator when the open / close switch is opened or closed, and at least when the drive control of the actuator toward the door close side is released, the door open / close device is manually operated. In an automobile automatic door device that is openable, the actuator drive There is a standby state setting circuit that can switch the circuit between a standby state in which the actuator can be driven according to the closing of the door opening / closing switch to each position and a non-standby state in which the actuator cannot be driven even when the switch is opened to each position. The standby state setting circuit provided in the actuator drive circuit switches to a non-standby state when the ignition key switch is opened, and waits when a standby state setting switch connected to the standby state setting circuit is set. It was decided to be configured to switch to the state.

(Operation) As a result of opening and closing the door manually due to an emergency,
Explain the operation when switching the ignition key switch from open to closed to open and close the door when the position of the door open / close switch does not match the open / closed state of the door. The state setting circuit switches the actuator drive circuit to the non-standby state, and the actuator is not driven.

Therefore, when the ignition key switch is closed in this state, the actuator does not drive regardless of the position of the door opening / closing switch. Therefore, as described above, even if the position of the door open / close switch and the open / closed state of the door are different, the actuator will not be driven regardless of the driver's will only by closing the ignition key switch.

In this case, in order to open and close the door, the standby state set switch is set. By this operation, the standby state setting circuit switches the actuator drive circuit to the standby state, so that the actuator drive circuit can drive the actuator in accordance with the position of the door opening / closing switch. , The actuator drive circuit drives the actuator to operate the door in the direction corresponding to the position of the door open / close switch. In this way, the driver drives the standby set switch intentionally, and the actuator is driven for the first time.

The door 20 can be opened and closed manually.

The emergency switch 26 and the manual opening / closing switch 8
Is opened, the vacuum cylinder 18 is connected to the manual position 162 of the three-position switching valve 16. At the manual position 162, the pressure of the vacuum source 22 is not applied and is released, so that the door 20 can be opened by hand.

Next, the operation of the first embodiment will be described.

For normal use when opening and closing the door with the ignition key switch 2 closed.

When the ignition key switch 2 is closed and the door opening / closing switch 6 is in the closed position 62, the door 62 is once put in the opening / closing position 61, and when it is in the open position 61 it is once put in the closing position 62 from the position 61.

When the door opening / closing switch 6 is in the open position 61, the coil 341 of the second relay switch 34 is excited through the diode 48 to close the contact 342, and is connected between the manual opening / closing switch 8 and the door opening / closing switch 6. The second relay switch 34 is held by itself even after the door opening / closing switch 6 is moved from the open position 61 to the closed position 62 by being supplied with power from the circuit.

After the second relay switch 34 is held by itself, when the door opening / closing switch 6 enters the closed position 62, the coil 381 of the fourth relay switch 38 is excited and the contact 382 is closed.

When the contact 382 of the fourth relay switch 38 is closed, current flows through the coil 401 of the fifth relay switch 40, the set display lamp 46, and the coil 321 of the first relay switch 32, and the coils 401 and 321 are excited, respectively.
Further, the contact 402 of the fifth relay switch 40 is closed, the power is supplied from the circuit passing through the fifth relay switch 40 connected between the manual opening / closing switch 8 and the door opening / closing switch 6, and the fifth relay switch 40 is self-held. It

At the same time, the contacts 322, 3 of the first relay switch 32
23 is closed and put in a standby state. When a current flows through the actuator drive circuit 31 in this state (by operating the door opening / closing switch 6), the open valve solenoid 10 or the close valve solenoid 12 which is an actuator is operated.

Therefore, after the door opening / closing switch 6 is closed → opened or opened → closed, the former is in the closed position because the door is closed, and the latter is in the open position because the door is opened, so that the door is opened → It can be operated from closed or closed to open.

In addition, the second relay switch 34 and the fifth relay switch 4
Since the self-holding relay is used for 0, the closing / opening operation or the opening → closing operation of the door opening / closing switch 6 may be performed once when the ignition key switch 2 is closed.

When you want to open the door manually in an emergency.

When the emergency switch 26 is opened, the closed solenoid valve 1
2 current stops flowing, and the spring 24 causes the valve 1
2 is returned and the pressure applied to the vacuum cylinder 18 is released.
It will no longer receive the power of and can be released by hand.

Further, when the manual opening / closing switch 8 is opened, current does not flow through both the closed solenoid valve 10 and the closed solenoid valve 12, the springs 24 return both valves 10 and 12, and the pressure applied to the valve cylinder 18 is released.
The door can be opened and closed by hand.

In addition, in order to return to the automatic opening / closing after manually opening or closing the door, in the manual opening / closing, the opened manual opening / closing switch 8 or the emergency switch 26 is closed, and then, as described above, the door opening / closing is performed. The switch 6 is operated from the open to the closed position or from the closed to the open position. At this time, of course, the ignition key switch 2 must be closed.

In normal use, the door open / close switch 6 is in the closed position 62 when the door 20 is closed, and when the door open / close switch 6 is moved from the closed position to the open position and then returned to the closed position, the door 20 is driven in the closing direction. However, since the door 20 is originally closed, it does not move. Similarly, when the door 20 is open, the door opening / closing switch 6 is in the open position 61, and even if the door opening / closing switch 6 is moved from the open position to the closed position and then put in the closed position again, the door 20 is originally open and does not move. .

The standby state is set as described above.

The open / close position of the door open / close switch 6 and the door 20
When the open / close status of does not match.

When the door open / close switch 6 is in the closed position 62 and the door 20
When is open.

When the ignition key switch 2 is closed, the current that has passed through the manual open / close switch 8 becomes the door pilot lamp 44.
Is turned on and the coil 361 is excited to pass through the open position 421 of the door switch 42 to reach the ground.

Further, since the contact 362 is opened by the excitation of the coil 361 and the contact 382 of the fourth relay switch 38 is not energized, the coils 321 and 401 of the first relay switch 32 and the fifth relay switch 40 are not excited and the actuator is driven. The circuit 31 remains in the non-standby state, and the closed valve solenoid 12 is not activated.

Next, when the door opening / closing switch 6 as a standby state setting switch is used to perform a setting operation for bringing the actuator drive circuit 31 into the standby state (in this case, the actuator is temporarily placed in the open position 61 and then in the closed position 62). A current flows from the closed position 61 of the door opening / closing switch 6 to the second relay switch 34 via the diode 48, the coil 341 is excited, and the second relay switch 34 is self-held with the contact 342 open.

Next, when the door opening / closing switch 6 is closed, the coil 381 of the fourth relay switch 38 is energized and the contact 382 is closed.

Then, the contact 382 of the fourth relay switch 38 is energized by the second relay switch 34 in the self-holding state, whereby the coil 401 and the set display lamp 46 of the fifth relay switch 40 are energized, and the fifth relay switch 40 is energized. Is self-holding with the contact 402 closed and the first
The coil 321 of the relay switch 32 is energized, and the actuator drive circuit 31 enters a standby state. The contacts 322 and 323 are closed by exciting the coil 321. Here, since the door opening / closing switch 6 is in the closed position 62, the closing valve solenoid 12 operates at the same time as the standby state and pushes the valve against the spring 24.
The valve is in the closed position 163 and the door 20 is closed.

The door opening / closing switch 6 is in the open position 61, and the door 20
When is closed.

When the ignition key switch 2 is closed, the power is supplied only from the manual open / close switch 8 to the contact points 323, 382 and 402 of the first relay switch 32, the fourth relay switch 38 and the fifth relay switch 40. Since the coil 321 of the relay switch 32 is not excited and the contact 323 is in the closed state, the actuator drive circuit 31 is in the non-standby state and the open valve solenoid 10 is not operated.

At this time, the second relay switch 34 is self-held with the contact 342 closed.

Next, when the set operation for bringing the actuator drive circuit 31 into the standby state (in this case, the operation of closing the door opening / closing switch 6 in the open position 61 into the closed position 62) is performed, the coil 381 of the fourth relay switch 38 is performed.
Is energized to close the contact 382.

Thereby, the fifth relay switch 40 is self-held in the contact 402 closed state, the set display lamp 46 is turned on, and the contact 322 of the first relay switch 32 is provided.
323 is closed, and the actuator drive circuit 31 enters the standby state.

Therefore, for the first time, the door open / close switch 6 is in the open position 61.
When it is returned to the position, the valve open solenoid 1
0 pushes the valve against the spring 24, the vacuum cylinder 18 is activated and the door 20 is closed.

When the position position of the door open / close switch 6 and the open / closed state of the door 20 match.

When the door open / close switch 6 is in the closed position 62 and the door 20 is closed.

When the ignition key switch 2 is closed, the contact 362 of the third relay switch 36 is closed, so that the contact 342 of the second relay switch 34 is closed and self-maintained, and the coil 381 of the fourth relay switch 38 is also excited. The contact 382 is closed in order to be closed.

Therefore, the coil 401 of the fifth relay switch 40 is excited to close the contact 402, and the state is maintained by itself, and the coil 321 of the first relay switch 32 is excited to close the contacts 322 and 323 to drive the actuator. The circuit 31 enters the standby state, and since the door opening / closing switch 6 is in the closed position 62, the closing valve solenoid 12 is operated to close the door 20, and the door 20 is closed.

However, since the door 20 is closed, the door 20 does not move.

Incidentally, the set display lamp 46 is turned on while the fifth relay switch 40 is held by itself.

When the door open / close switch 6 is in the open position 61 and the door 20 is open.

When the ignition key switch 2 is closed, the contact 342 of the second relay switch 34 is self-held in the closed state.
Here, the fourth relay switch 38 is not energized and the fifth relay switch 38 is not energized.
Since the relay switch 40 is not energized and the door switch 42 is in the door open position 421, the coil 361 of the third relay switch 36 is excited and the contact 362 is opened. Therefore, since the coil 321 of the first relay switch 32 is not excited, the actuator drive circuit 3
1 is a non-standby state, and the open valve solenoid 10 is not operated.

Since the door 20 is open, it does not have to be operated.

Next, a second embodiment shown in FIG. 2 will be described.

In the second embodiment, the flip-flop circuit 52 and the first
The standby state setting circuit 30 including the second AND circuits 54 and 56 and the one-shot multivibrator 58 is connected to the actuator driving circuit 31, and the standby state setting switch 50 drives the actuator via the standby state setting circuit 30. This is an example of connecting to the circuit 31.

The first AND circuit 54 is the actuator drive circuit 3
When the set signal a provided from the flip-flop circuit 52 and the open signal b output when the door opening / closing switch 60 is put in the open position 61 are input, Open valve solenoid 10
The open operation signal d is output to.

The second AND circuit 56 is the actuator drive circuit 3
1, and the set signal a from the flip-flop circuit 52 and the door opening / closing switch 6
When the closing signal c, which is output when 0 is input to the closing position 62, is input, the closing operation signal e is output to the opening valve solenoid 12.

Therefore, when the set signal a is input to both the AND circuits 54 and 56, the actuator drive circuit 31 enters the standby state.

The flip-flop circuit 52 has a set side S connected to the manual open / close switch 8 via the standby state set switch 50, and a reset side R via the one-shot multivibrator 58. The flip-flop circuit 52 outputs a set signal a to both AND circuits 54 and 56 when it is input to the set side S to put the actuator drive circuit 31 in a standby state, and when it is input to the reset side R, a reset signal is input. f is output to put the actuator drive circuit 31 in the non-standby state.

The standby state set switch 50 is provided between the manual open / close switch 8 and the flip-flop circuit 52, and when the ignition key switch 2 is turned on in the closed state, the flip-flop circuit 52 is set to the set state. . At this time, the flip-flop circuit 52 becomes an output 1 (ON), and one input of the first AND circuit 54 and the second AND circuit 56 is set to 1.

The standby state set switch 50 returns to the original state and becomes the non-closed state when the hand is released.

The one-shot multivibrator 58 outputs a signal to the reset side R of the flip-flop circuit 52 at the moment when either the ignition key switch 2 or the manual open / close switch 8 is opened. At this time, the flip-flop circuit 52 outputs 0
(OFF), and one input of the first AND circuit 54 and the second AND circuit 56 is set to 0.

Therefore, according to the apparatus of the second embodiment, when the standby state set switch 50 is turned on after the ignition key switch 2 is closed, the actuator drive circuit 31 enters the standby state, and when the ignition key switch 2 or the manual opening / closing switch 8 is opened. Until the standby state set switch 50 is turned on again, the non-standby state is set. In the standby state, when the door open / close switch 60 is set to the open position 61 or the closed position 62, both inputs of the first AND circuit 54 and the second AND circuit 56 become 1,1.
The output of either the first AND circuit 54 or the second AND circuit 56 becomes 1, and the door 20 is opened or closed. Further, in the non-standby state, the first AND circuit 54 and the second AND circuit 56
One input (input from the flip-flop circuit) is 0
The output of both the first AND circuit 54 and the second AND circuit 56 becomes 0, and the door 20 does not move. Therefore, even if the ignition key switch 2 is turned off once and then the ignition key switch 2 is closed again, the door 20 does not move. Since the other construction and operation of the second embodiment are the same as those of the first embodiment, the same reference numerals are given and the description thereof is omitted.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and the present invention can be applied even if there is a design change or the like within a range not departing from the gist of the present invention. included.

For example, the standby state setting circuit 30 is activated by turning on the standby state setting switch 50.
May be any circuit as long as it is in a standby state and is in a non-standby state when the ignition key switch 2 is turned off. The door opening / closing device 14 may use hydraulic pressure or other fluid pressure, a motor, or the like, instead of using a vacuum.

(Effects of the Invention) As described above, according to the automobile automatic door apparatus of the present invention, the actuator is operated based on the open / close position of the door opening / closing switch even if the driver does not have the intention of closing the key switch. Since it is possible to prevent the door from being opened and closed by being actuated, a malfunction of the door at the time of starting the vehicle may cause an occupant or an object to be caught in the door, or the door may be struck. It is possible to obtain an effect that it is possible to prevent the applied object from falling or falling.
