AI Technical Summary

Technical Problem

Conventional vehicle door opening devices are large in the radial direction due to separate shafts for the screw and barrel cam, and making the switch waterproof increases costs and risks water ingress.

Method used

The device locates the switch radially away from the push lever and uses a switch lever coaxially aligned with the spindle to convert linear motion into rotational motion, ensuring compactness and waterproofness without needing a waterproof switch.

Benefits of technology

This configuration allows for a more compact design that prevents water ingress, reducing costs by using a standard switch.

Abstract

To make a device smaller and to ensure waterproofness of a switch.SOLUTION: A vehicle door opening device is installed on either of a vehicle body or a door to press the other of the vehicle body and the door, thereby opening the door. The vehicle door opening device includes a spindle that is rotationally driven by a motor, a push lever that moves back and forth in the axial direction of the rotation axis of the spindle as the spindle rotates to press the other of the vehicle body and the door, a switch that is disposed at a position radially spaced apart from the push lever, and a switch lever that is interposed between the push lever and the switch and is disposed rotatably coaxially with the spindle to convert the linear motion of the push lever into rotational motion to operate the switch.SELECTED DRAWING: Figure 3
