  • Patent number: 8960738
    Abstract: A vehicle door handle device is configured so that, after a frame is assembled to an outer panel of a slide door, a link base, a connecting link, and a hand grip are mounted to the frame. Next, a lever and a cap are mounted to the hand grip and the frame, thereby assembling each component member to the outer panel. When the hand grip is moved through a door opening operation in the same direction as a slide door opening direction, an operation force for releasing a fully closed latch mechanism, which retains the slide door in a fully closed state, is generated. In addition, when the hand grip is moved through a door closing operation in the same direction as a slide door closing direction, an operation force for releasing a fully opened latch mechanism, which retains the slide door in a fully opened state, is generated.

  • Patent number: 8901423
    Abstract: Provided is a wiring holding structure, wherein wiring for electrically connecting a vehicle body to the vehicle sliding door is held in the vehicle body. The wiring holding structure comprises a step member provided adjacent to the vehicle sliding door and a holding portion for holding the wiring. The step member is molded of plastic material. The holding portion is for holding the wiring. The holding portion comprises a first holding portion integrally molded onto the step member; and a second holding member that is fixed to face the first holding section. The second holding member holds the wiring together with the first holding portion. The number of components necessary for the wiring holding structure can thereby be reduced, and the size of the wiring holding structure is made more compact.

  • Publication number: 20140245666
    Abstract: A door opening/closing device for use in a vehicle is provided with a driving member. The driving member has a permanent-magnet motor provided with two terminals and an output member, which is rotationally driven by the permanent-magnet motor. The driving member is mounted on either a vehicle body or a vehicle door and is coupled to the other via the output member. As the output member rotates, the vehicle door opens or closes. The door opening/closing device is also provided with a switching device configured to switch the permanent-magnet motor between an energizable state, in which the permanent-magnet motor can receive electricity through the two terminals, and a brake state, in which the terminals are short-circuited. The switching device switches the permanent-magnet motor into the brake state when the vehicle door is in any position other than the fully closed position.

  • Publication number: 20130058750
    Abstract: A hybrid construction machine is capable of performing satisfactory operations even when trouble occurs that disables the electric motor from outputting torque. The hybrid construction has both a hydraulic motor and an electric motor driving the swing structure and a controller for switching between a hydraulic/electric hybrid swing mode (using both the hydraulic motor and the electric motor) and a hydraulic-alone swing mode (using only the hydraulic motor). The switching is executed while achieving satisfactory operability and performance in each mode. Normally, an energy saving operation is performed in the hydraulic/electric hybrid swing mode. When the electric amount of an electricity storage device has gone out of a prescribed range or an abnormality has occurred in an electric system (e.g., failure of an inverter), the swing mode is switched to the hydraulic-alone swing mode so that driving with normal braking torque is possible by the hydraulic motor alone.
