In such a sliding door, various electrical devices such as an actuator and a control device are built into the door, and it is necessary to supply power to these electrical devices from a power source (battery) or the like on the vehicle body side.

However, in cases where the entire door slides relative to the vehicle body, such as a sliding door,
It is not possible to connect the electrical equipment on the sliding door side and the power supply on the vehicle body side using only conductive wires.

Therefore, for example, as disclosed in Japanese Utility Model Application Publication No. 61-87416, a power supply device with movable contacts that can be retracted and retracted is installed on the vehicle body side and the sliding door side, and these contacts come into contact with each other when the door is closed. With this, power is supplied from the vehicle body side to the door side.

[Problem that the invention attempts to solve]

The above-mentioned power supply device continues to supply power from the vehicle body side to the door side even after the various electrical devices on the sliding door side are activated, so if the vehicle is parked for a long time with the sliding door closed, it will not run out of battery. There is a risk of over-discharging or overheating of various electrical devices.

The present invention has been developed to solve the above-mentioned problems, and is capable of automatically stopping power supply after a certain period of time has elapsed after power is supplied to the opening/closing body of an automobile, thereby preventing battery build-up, etc. The purpose is to provide a power supply device for

[Means for solving problems]

In order to achieve the above object, the present invention provides a pair of power supply connectors, one of which is provided on the vehicle body side and the other on the opening/closing body side, so that when the opening/closing body is closed, the contacts between these two In a power supply device that supplies power from the vehicle body side to the opening/closing body side through contact between the two, the opening/closing body is actuated by the opening/closing body when the opening/closing body closes to a predetermined slightly open position. It is characterized by providing a power supply switch that starts power supply, and a timer that stops power supply to the opening and closing body side after a certain period of time has elapsed from the start of power supply to the switching body side by the operation of the power supply switch.

[Effect]

When the opening/closing body is closed to a predetermined intermediate position, the power supply connectors on both the vehicle body and the opening/closing body come into contact, and power supply to the opening/closing body is started.
At the same time, a timer is activated and, for example, when the opening/closing body is completely closed and a certain period of time has elapsed, power supply to the vehicle body side is automatically stopped.

Therefore, power to the electrical equipment provided on the vehicle body or the opening/closing body is also cut off.

7 (see FIG. 1).

In FIG. 1, the center pillar 2a of the vehicle body 2
A power supply switch 28 that is turned on and off by the sliding door 1 is provided nearby, and when the sliding door 1 is closed, this switch 28 is placed a little before the latch (not shown) in the door lock device 3 reaches the half-latched position. only for a short time
It is now activated.

The power supply switch 28 is electrically connected to the controller 26 through a conductive wire 29, and the power supply switch 28 and the controller 26 control the power supply to the power supply connector 8 on the vehicle body 2 side.

Next, the operation of the above embodiment will be explained with reference to the circuit diagram of FIG.

The sliding door 1 is closed and the power supply switch 28 is turned on.
automatically and for a short time by sliding door 1.
When turned on, the relay R ₁ provided in series with the power supply switch 28 and the recovery delay timer 30 provided in parallel with the relay R ₁ are energized at the same time in the controller 26, and the self-holding circuit causes contact R to be energized. _1-1 and timer contact 30a close,
Electricity is supplied from the battery 27 to the power supply connector 8 on the vehicle body 2 side.

The timer 30 starts counting a certain period of time from this time.

When the sliding door 1 reaches just before the half latch, the contact 1 of the moving shaft 10 in the power supply connector 7
0a comes into contact with the contact point 22a of the moving shaft 22 on the vehicle body 2 side, and at that instant, the slide door 1 is opened from the vehicle body 2 side.
Power supply starts to the side.

From this state, when the door 1 is further closed and reaches the half-latched position where the latch in the door lock device 3 and the striker on the vehicle body (both not shown) are barely engaged, that is, the sliding door 1 is in the ajar state. When this happens, the rear end of the moving shaft 10 retracted backward comes into contact with the movable contact 17 of the half-latch detection switch 13, thereby making them electrically conductive with each other, and a detection signal is provided on the door 1 indicating that the half-latch is immediately established. Issued to controller 5.

When the sliding door 1 remains in the half-latched state and cannot be closed any further, the relay _R3 is energized by the closing action of the normally closed contact _R2-1 in the relay _R2 provided in the controller 5.
With the operation of this movable contact R _3-1 to the normally open side,
A motor 31 in the closure 4 is driven to rotate in one direction.

The rotation of the motor 31 causes the drive gear 32 to rotate clockwise in FIG. It is rotated counterclockwise towards the position.

When the sector gear 33 rotates, the drive lever 35 integrated with the sector gear 33 moves the close lever 37 pivotally connected to the bracket 36 of the door lock device 3.
Hold the wire 38 and rotate it counterclockwise in plan view.

As a result, the latch in the half-latched position is forcibly rotated by the protruding lever 39 protruding from the latch to the full-latched position using one arm of the close lever 37, and the slide, which was in the ajar state, is forcibly rotated to the full-latched position. Door 1 is completely closed.

When the latch becomes fully latched, the other arm of the close lever 37 comes into contact with the full latch switch 40 provided on the bracket 36 to close it, and by energizing relay _R2 ,
Contact R _2-1 , which had been normally closed, operates to the normally open side and is self-maintained, and at the same time, the contact of relay R _3
R3-1 operates to the normally closed side and stops the motor 31.

Also, at this time, since the normally open contact of the limit switch 41 provided at the rear of the sector gear 33 has already been closed by the rotation of the sector gear 33, the movable contact R _4-1 of the relay R ₄ is on the normally open side. The motor 31 rotates in the opposite direction. As a result, the sector gear 33 is rotated clockwise and returned to its original position, and at the same time, the limit switch 41 is turned OFF.
The movable contact R _4-1 in the relay R ₄ returns to the normally closed state, and the motor 31 immediately stops.

When the closure 4 is activated and the sliding door 1 is completely closed, the timer 30, which has been timing immediately after the power supply switch 28 is activated, operates.
After a certain period of time, the power to relay _R1 is cut off,
The power supply to the power supply connector 8 is automatically stopped.

As a result, not only the relays on the vehicle body 2 side, but also the relays on the sliding door 1 side and other various electrical devices are all disabled.
It becomes OFF. Therefore, even if the vehicle is left parked for a long time, there is no risk of over-discharge of the battery or overheating of the relay, etc.

By providing a power supply switch 28 near the center pillar 2a of the vehicle body 2 that starts power supply slightly before the sliding door 1 reaches the half-latched position, the power supply to the vehicle body 2 side can be switched on when the sliding door 1 is open. At the contact 22a of the connector 8,
There is no risk of being shot even if a metal object hits it, making it highly safe.

It goes without saying that the present invention can also be applied to back doors, side doors, trunk lids, etc. in addition to the above-mentioned sliding doors.

[Effect of idea]

According to the present invention, the following effects can be achieved.

(a) By installing a power supply switch and a timer, when the opening/closing body is open, power will not be supplied to the contacts of the power supply connector on the vehicle body side. Even if a metal object hits the contacts of the power supply connector, there is no risk of it being shot, making it highly safe.

(b) Since the power supply connector on the vehicle body side is energized only for a certain period of time after the power supply switch is activated and the contacts of both power supply connectors come into contact with each other and the timer finishes operating, the vehicle body or opening/closing body is The various electrical devices provided are not constantly energized, so over-discharging of the battery and overheating of the electrical devices can be prevented.
