Abstract

PURPOSE:To provide an power feeding system in which a slider door closure detecting switch is removed. CONSTITUTION:In the half door state where a slide door is closed, the turning-ON signal of a half latch switch 20 is feedback-treated through the center terminal 35b of the second junction switch 35a signal input terminal 4 of electricity feeding ECU1 logic circuit 3, and an electricity feeding relay 2 is operated by the control signal outputted from the logic circuit 3, and the battery voltage is applied to an easy closer ECU 11, and an electricity supplied state is generated. If the slide door is opened after the full lock or during the time when the electricity feeding relay 2 is in operation, the half latch switch 20 is turned OFF, and each terminal of the first and the second junction switches 31 and 34 is separated. In substitution for the half latch switch, each turning-ON timing of the center terminal 35a and 35b is delayed in comparison with the turning-ON timing of each another terminal, and the turning-OFF timing may be accelerated in comparison with the turning-OFF timing of each another terminal.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply system for sliding doors.

[0002]

2. Description of the Related Art A power supply system for a slide door includes a power supply control unit equipped with a power supply control circuit and a power supply relay, and a power supply terminal on the body side and a power supply terminal on the slide door side for supplying power from the body side. It is composed of a junction switch for contact and a switch for detecting the closing of a sliding door. Then, based on the operation of the switch for detecting the closing of the sliding door, the power is supplied only when the sliding door is closed. Generally, the junction switch is arranged in a body opening opened and closed by a slide door. In addition, the switch for detecting the closing of the sliding door can detect the position of the bracket of the upper roller or the lower roller of the sliding door,
It is arranged on a rail that guides each roller.

[0003]

As described above, the switch for detecting the closing of the slide door cannot be installed due to the structure of the body, or the slide door may be erroneously mounted due to variations in component accuracy, mounting errors, or the like. Even if the closing detection position is displaced, even if the sliding door is closed, power may not be supplied to the electric mechanism arranged in the sliding door and the electric mechanism may not operate. Further, since the mounting position and space of the switch for detecting the slide door closing are limited, the structure and mechanism of the switch becomes complicated, and a separate switch for detecting the slide door closing is required, resulting in high cost. There was a point. SUMMARY OF THE INVENTION It is an object of the present invention to provide a power supply system which eliminates the slide door closing detection switch in order to solve the above problems.

[0004]

In order to achieve the above object, the power supply system for a slide door of the present invention according to claim 1 supplies power from the body side to an electric lock mechanism arranged on the slide door. Therefore, in a slide door power supply system including a junction switch that is connected when the slide door is closed, an ON / OFF signal of a half latch switch provided in the electric lock mechanism is fed back through the junction switch, and the body side is connected. It is characterized in that the power supply relay provided in the above is controlled to perform power supply or power supply stop.

In order to achieve the above object, the power supply system for a slide door of the present invention according to claim 2 supplies power to the electric lock mechanism arranged on the slide door from the body side. In a power supply system for a slide door equipped with a junction switch that is connected when the slide door is closed, when the slide door is closed, the timing at which the power supply relay control junction switch is turned on is delayed compared to the power supply junction switch, and the slide door is closed. Is opened, the timing at which the power supply junction switch is turned off is delayed relative to the power supply relay control junction switch.

[0006]

In the power supply system for the sliding door according to the first aspect of the present invention, when the sliding door is closed to connect the terminals of the junction switch and the half-latch switch provided in the electric lock mechanism is turned on. The signal fed back through the junction switch activates the power supply relay to start power supply to the electric lock mechanism in the slide door. When the sliding door is opened, the half latch switch is turned off and the power supply is stopped. Therefore, since the closing of the slide door is confirmed by the half-latch switch, the switch for detecting the slide door closing can be eliminated, and the operation does not become unstable depending on the mounting position of the switch, and This has the effect of simplifying the physical structure and realizing it at low cost.

Further, in the power supply system for a slide door according to the second aspect of the present invention, when the slide door is closed, the power supply relay control junction switch is turned on after the power supply junction switch is turned on. Power supply to the electric lock mechanism inside is started. When the sliding door is opened, after the junction switch for power supply relay control is turned off and power supply is stopped,
The power junction switch turns off. As a result, a switch for detecting the closing of the sliding door is provided separately,
There is no need to confirm the closing of the sliding door. In addition, since the power is not supplied when the junction switch for power supply is turned on and off, it is possible to prevent the occurrence of sparks and prevent a short circuit even if a malicious operation is performed on the exposed junction switch by opening the slide door. There is an effect that can be done.
