(Embodiment) FIG. 1 is a circuit diagram showing the electrical components of the first embodiment of the present invention.

The lock switch 1 is provided in the driver's seat of the vehicle,
An automatic reset type two-pole switch is used. That is,
When not in operation, the movable contact 1c is in the neutral position, and the movable contact 1c can be temporarily closed to the unlock side contact 1b or the lock side contact 1a by the driver's operation.

A driver's seat door circuit 10 and a passenger's seat door circuit 20 are connected to the lock switch 1. Further, although not shown, the same circuit as the passenger door circuit 20 is provided for the left and right rear doors, and these are also connected to the lock switch 1.

The driver's door circuit 10 has an inside handle switch 1
2, outside handle switch 11, keep relay 13, electric actuator 19, and diode D
1 to D4.

The inside handle switch 12 is a switch that is turned on when an inside handle (not shown) provided inside the driver's door is operated, and the outside handle switch 11 is an outside handle (not shown) provided outside the driver's seat door. This switch is turned on when (omitted) is operated.

The keep relay 13 is a so-called operation-holding type relay. When the relay coil 14 is energized, the movable contact 16 closes to the contact 17 side, and when the relay coil 15 is energized, the movable contact 16 moves to the contact 18 side. close. Relay coil 14
Is connected to the unlock side contact 1b of the lock switch 1 via the diode D2, and the relay coil 15
Is connected to the lock side contact 1a.

The movable contact 16 of the keep relay 13 and the movable contact 1c of the lock switch 1 are connected to the battery 2.

The outside handle switch 11 is the keep relay 1
3 is connected to the contact 17 and the inside handle switch 12 is connected to the keep relay 1 via the diode D4.
3 is connected to the contact 18.

The diode D3 is connected between the contact 17 of the keep relay 13 and the cathode of the diode D4.

The inside handle switch 12 and the outside handle switch 11 are connected to an electric actuator 19, and a detour 50 is provided from a connection point between the outside handle switch 11 and the inside handle switch 12.
Is connected to the relay coil 14 of the keep relay 13 via the diode D1.

The electric actuator 19 is provided between the driver's door and the body and drives a door lock mechanism for locking and unlocking the driver's door.
Has a configuration as shown in FIG.

The latch 63 is attached rotatably around a pin 64, and is biased in the N direction in the figure by a spring 62 and a pin 65.

The latch 63 is formed with a locking portion 63a and a groove 63b, and a striker 68 fixed to the body side is fitted into the groove 63b.

Further, below the latch 63, there is provided a pole 61 that is rotatably mounted around a pin 72 and that is biased by a spring 70 in the L direction in the drawing.

The tip portion of the pawl 61 engages with the locking portion 63a of the latch 63 when the actuator 19 is inactive, and blocks the rotation of the latch 63, thereby holding the door in the locked state.

Further, when the actuator 19 operates, the rod 69 linked to the tip of the pole 61 is pulled, whereby the pole 61 rotates in the M direction in the drawing to the position indicated by the two-dot chain line in the drawing. When moved, the latch 63 is unlocked. Therefore, when the latch 63 rotates by a certain angle regulated by the pin 65 and the long hole 66 by the biasing force of the spring 62 and shifts to the position shown by the chain double-dashed line in the figure, the striker moves from the groove 63b of the latch 63. 68 can be detached and the door is unlocked.

The passenger door circuit 20 and the rear door circuit (not shown) are

The outside handle switch 21 is a keep relay 2
3 is connected to one contact 27, and the inside handle switch 22 is connected to the outside handle switch 21.
Are connected in parallel.

The outside handle switch 21 and the inside handle switch 22 are connected to an electric actuator 29.

Next, the operation of this embodiment will be described.

First, a case where the doors are locked from a state where all the doors are unlocked will be described.

When all the doors are closed, the driver operates the lock switch 1 toward the lock side contact 1a, so that the keep relays 13 and 23 of each door circuit are closed while the lock side contact 1a is closed. The relay coils 15 and 25 are energized, the movable contact 16 is closed to the contact 18 side, and the movable contact 26 is connected to the contact 2
Close to side 8.

As a result, in the passenger seat door circuit 20 and the rear door circuit, the movable contact 26 is connected to the contact 28 to which nothing is connected.
Is closed, the power supply path of the battery 2 is cut off, and the electric actuator 29 is held in the inoperative state.
Therefore, even if the inside handle or the outside handle is operated in this state, that is, the inside handle switch 22 or the outside handle switch 21
When the switch is turned on, the electric actuator 29 does not operate and the door is locked.

In the driver's door circuit 10, by energizing the relay coil 15, the movable contact 16 of the keep relay 13 closes to the contact 18 side, and the outside handle switch 11
It becomes impossible to supply battery power to the electric actuator 19 through.

However, the driver is required to get out of the vehicle as necessary, so that the diode D4 is connected between the contact 18 and the inside handle switch 12 so that even if all the doors are locked. By operating the inside handle of the driver's seat door, the driver closes the inside handle switch 12, energizes the electric actuator 19, and unlocks the driver's seat door.

With the turning on of the inside handle switch 12,
Since a current also flows through the relay coil 14 via the bypass 50, the movable contact 16 closes to the contact 17 side (the lock switch 1 returns to the neutral position after the driver's operation and the relay coil 15 is not energized. Has stopped).

Also, in this state, the outside handle switch 1
Since the electric actuator 19 can be energized even when the switch 1 is turned on, the driver who once exits the vehicle can open the driver's seat door from the outside of the vehicle and return to the inside of the vehicle.

The driver who returns to the inside of the vehicle operates the lock switch 1 in the direction of the lock side contact 1a again, so that the keep relay 13
The movable contact 16 is closed to the contact 18 side so that the door cannot be opened from the outside of the vehicle by operating the outside handle.

Even when the inside handle switch 12 or the outside handle switch 11 of the driver's door circuit 10 is operated, the current from the bypass 50 is blocked by the diode D2 in the other doors.
The movable contact 26 of No. 2 remains closed on the contact 28 side, and the door cannot be opened.

Next, a case where unlocking is performed from a state in which all doors are locked will be described.

In this case, when the driver operates the lock switch 1 toward the unlock side contact 1b, the keep relays 13 and 23 of each door circuit are energized, and the movable contacts 16 and 26 are closed to the contacts 17 and 27. As a result, the electric actuators 19 and 29 are allowed to be energized. By operating the inside handle or the outside handle of each door, the electric actuator of the door provided with the operated handle is energized. Then, the door is unlocked and opened.

The diode D1 functions to prevent the electric actuator 19 from being energized via the bypass 50 when the lock switch 1 is closed to the unlock side contact 1b.

Next, FIG. 3 is a circuit diagram showing the electrical components of the second embodiment of the present invention. In the figure, the same components as those of the embodiment shown in FIG. 1 are designated by the same reference numerals and the description thereof will be omitted.

In the present embodiment, a diode D5 is interposed between the inside handle switch 12 and the electric actuator 19, and instead of the bypass 50 in FIG. 1, a bypass from the anode side of the diode D5 to the relay coil 14 is bypassed. Road 5
1 is provided.

With this configuration, in addition to the operation of the first embodiment, this embodiment has the relay coil 14 when the outside handle switch 11 is turned on when the keep relay 13 is closed to the contact 17 side. It is possible to prevent unnecessary current from being applied to the device.

Next, FIG. 4 is a circuit diagram showing the electrical components of the third embodiment of the present invention. In the figure, the same components as those of the first embodiment shown in FIG. 1 are designated by the same reference numerals and the description thereof will be omitted.

In this embodiment, the diode D2 in the first embodiment is excluded.

With this configuration, the lock switch 1 according to the present embodiment is provided.
Is operated in the direction of the lock side contact 1a to lock all the doors, and when the driver operates the inside handle, all the current flowing through the bypass 50 by turning on the inside handle switch 12 is After the relay coils 14 and 24 of the door circuit are energized and the driver once exits the vehicle, other occupants can freely open the door by operating the inside handle or outside handle to get on and off. It is convenient.

However, the condition is that the inside handle of the driver's door is operated.

The electric actuators 19 and 29 are not limited to electromagnetic actuators, and other electric actuators such as ordinary motors and step motors can be used.

(Effect of the Invention) As described in detail above, according to the present invention, even when all the doors are locked in the driver's seat by the lock switch, at least the driver can freely open the doors. This has the effect of making getting on and off convenient.
