  • Patent number: 11560050
    Abstract: In the lid opening and closing device, the rotating body at the initial position rotates to one side in the rotation direction, so that the lock member is disengaged from the first link. Further, the first link and the rotating body are provided with a differential connecting mechanism, and the differential connecting mechanism connects the rotating body and the first link to operate the link mechanism at the retracted position after the lock member is disengaged from the first link, when the rotating body is rotating. As a result, the differential connecting mechanism imparts a time difference between the two operations of the rotating body. Therefore, the lock member and the link mechanism can be operated by rotationally driving the rotating body by a single actuator.

  • Patent number: 11480006
    Abstract: A vehicle door opening/closing device including a drive mechanism for driving the opening/closing of a door of a vehicle; a first detector and second detector for detecting the distance to an item to be detected which is positioned in a first detection range outside the vehicle or a second detection range which is closer than the first detection range; and a controller for controlling the drive mechanism, based on the detection results of the detectors. The controller prepares for the opening/closing of the door by the drive mechanism, by having the first and second detectors detect that an item to be detected has moved from the start area which is an area that overlaps the first detection range, to a trigger area which is an area that overlaps the second detection range, in the range of operation at a predetermined interval in the width direction of the vehicle.

  • Patent number: 11459813
    Abstract: A door opening and closing device includes: first and second detectors repeatedly detect a distance to a detection target around the door; and a control unit opens and closes the door using a drive unit when a predetermined operation having a plurality of stages performed by a moving object is detected. The control unit determines whether first and second objects respectively detected by the first and second detectors are the moving or stationary object. When one of the first and second objects is the moving object and the other is the stationary object and a distance to the stationary object is shorter than a first determination value, both the detection results of the first and second detectors are used for detection at a final stage, and only the detection result of the first or second detector detecting the moving object is used for detection at the other stages.
