Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a device in which power supply to a plurality of electric devices is controlled by a timer.

[Conventional technology]

For example, in a box-shaped vehicle having sliding doors on both sides, when each sliding door is closed from an open state to a predetermined position, a closure is one of the electric devices provided in the sliding door. An apparatus as shown in FIG. 2 is used to operate the closure by supplying power to the apparatus for a certain period of time.

The closure is provided in each slide door, and when the slide door reaches a predetermined half-latch position, the latch of the door lock is engaged with the striker fixed to the vehicle body by driving means such as a motor. The sliding door is automatically closed from the half-latch position to the fully closed position, and when the sliding door reaches the fully closed position, the operation of the driving means is automatically stopped. In addition,
After the sliding door reaches the fully closed position, the motor as the driving means reverses to the original position, and when the motor reaches the original position, the operation of the driving means is automatically stopped (for example, JP-A-1-182480, JP-A-1-187278, etc.).

The device shown in FIG. 2 includes a first power supply control device (02) connected to a first power supply connector (01) for supplying power from the vehicle body to one slide door, and a second power supply for supplying power from the vehicle body to the other slide door. A second power supply control device (04) connected to the connector (03).

FIG. 1 and the second power supply control device (02) (04) have the same configuration as each other, and are respectively connected between the power supply (05) and the first or second power supply connector (01) (03). The output signal is output from the output terminal (08) until the set time elapses after the signal is input to the input switch (06) and the input terminal (07), thereby closing the power supply switch (06). When the relay (09) is energized and a signal is input to the reset terminal (010), the timer (T) that starts counting the set time from the beginning, the power supply (05) and the timer (T) When connected between the input terminal (07) and each sliding door is closed to a predetermined position,
An operation switch (011) which is brought into contact with the sliding door to be momentarily closed, and a first or second power supply connector (0
1) Measure the current passing through a resistor (012) connected between (03) and the power supply switch (06), and when the current value exceeds a predetermined value, reset the timer (T). A current detection device (013) that sends a reset signal to (010),
Operation switch (011) and timer (T) input terminal (07)
Of the self-holding circuit (014) for the operation switch (011) connecting the intermediate point between the power supply switch (06) and the resistor (012) to the input terminal (07) of the timer (T). And a diode (D) that is provided on the way and allows only the current flowing toward the input terminal (07) of the timer (T) and blocks the current in the reverse direction.

When each slide door closes to a predetermined position and the operation switch (011) is closed, a timer (T) operates,
At the same time, the relay (09) is energized, the power supply switch (06) is closed, and the first or second power supply connector (01)
Power is supplied to (03).

Then, when the sliding door is further closed to the half-latch position and the closure is activated, the resistance (01
The current passing through 2) is detected by the current detection device (013), and when the current value exceeds a set value, a reset signal is sent from the current detection device (013) to the reset terminal of the timer (T).

Immediately after the reset signal is output from the current detection device (013), the timer (T) restarts measuring time, and when a set time longer than the operation time of the closure has elapsed, the output terminal (08) of the timer (T). No output signal is output, the relay (09) is demagnetized, the power supply switch (06) opens,
Power supply to the first or second power supply connector (01) (03) is stopped.

As is apparent from the above configuration, the timer (T) stops the power supply after a lapse of a predetermined time from the moment when the operation switch (011) for starting the power supply is instantaneously operated, and wastes the door. It is provided to prevent power supply.

On the other hand, in the current detection device (013), a situation where the set time of the timer (T) elapses while the electric device such as the closure in the door is operating and the electric device stops in an undesirable state. The above-mentioned object is achieved by resetting the timer (T) when the detected current becomes equal to or greater than a set value.

In this way, by combining the timer (T) and the current detection device (013), it is possible to prevent useless power supply and also prevent inconvenience that power supply is stopped during operation of the electric device. It has become.
