BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic opening and closing slide door.

[0002]

2. Description of the Related Art A conventional automatic opening / closing sliding door has a structure in which a sliding door disposed on a side of a vehicle body is moved from a front side to a rear side to open the door. Automatically opens and closes. Such a slide door is provided with a check holding mechanism to prevent the slide door from moving in the closing direction due to its own weight when the slide door is fully opened in a state where the front side of the automobile is stopped on a slope or the like on the lower side. The check holding mechanism includes a full-open stopper formed of a leaf spring near the full-open position of the guide rail, and holds the full-open position by a resistance force due to elastic deformation when the slide door gets over the full-open stopper. .

When such a sliding door is normally closed, it is necessary to move the sliding door against the elastic deformation of a fully-open stopper made of a leaf spring. It will be burdensome.

[0004] In order to solve such a problem, as disclosed in Japanese Patent Application Laid-Open No. H11-107606, there has been proposed a fully-open lock device that meshes with a striker provided on the vehicle body side at a fully-open position. In such a fully open lock device,
Since the operating force is light and it is held by engagement, the reliability is high. Such a fully open lock device and a fully closed lock device are:
When one is engaged, the other is not engaged.

[0005] Therefore, it is desired to employ a fully-open lock device for the automatic opening and closing slide door, and as a power supply method to the slide door, a technique such as a flexible cable which is a power supply method that can always supply power when the door is opened has been proposed. Therefore, it has become possible to employ a fully-open lock device for the automatic opening and closing slide door and electrically operate the fully-open lock device.

[0006]

However, when a dedicated driving device is added to drive the full-open lock device, the manufacturing cost of the driving device is high, which causes an increase in cost. Further, the structure inside the sliding door becomes complicated, and the control for operating the full-open lock device is added, so that the structure becomes complicated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an automatic opening / closing sliding door which has a reduced number of parts and cost, and has a simple structure and control.

[0008]

According to the first aspect of the present invention,

An automatic lock device that includes at least a fully-open lock device that controls the closing operation of the slide door by engaging the fully-open lock striker when the slide door is fully opened, and a lock control device that can control the fully-close lock device and the fully-open lock device. In the opening / closing slide door, the lock control device slides by releasing the engagement between the outside lever connected to the driving device and the fully closed lock striker of the fully closed lock device while moving with the outside lever. A release lever that enables the door to be opened; A fully-open lock lever that releases the engagement of the device with the fully-open lock striker and allows the slide door to be closed, a fully-open lock release transmission member that connects the fully-open lock lever and the fully-open lock device, the release lever, A fully-closed lock release transmission member that connects the fully-closed lock devices, and when the outside lever is swung by the drive device, rotation is transmitted to the release lever and the fully-open lock lever. The fully closed lock release device is released via the fully closed lock release transmission member, and the fully open lock device is released via the fully open lock release transmission member.

According to the first aspect of the present invention, the operating force can be transmitted to the fully-closed lock device and the fully-opened lock device by the conventional drive device for releasing the fully-closed lock device, so that one expensive drive device is provided. As a result, costs can be significantly reduced. Also, the structure of the sliding door and the control of the actuator are simplified.
