Abstract
A power child lock device includes a rotation driving mechanism, a switch link connected to the rotation driving mechanism so as to be moved vertically by a rotational force of the rotation driving means, an inside handle lever cooperatively connected to an inside handle installed in a door of a vehicle, a release lever connected to a door catch and configured to lock or release the door catch, and a power child lever configured to selectively connect or separate the inside handle lever and the release lever by being moved by the switch link.
Claims20
A power child lock device comprising:
- a rotation driving mechanism, wherein the rotation driving mechanism is a drive motor capable of rotating clockwise and counterclockwise, the drive motor having a worm integrally rotatable therewith;
- a switch link connected to the rotation driving mechanism so as to be vertically movable by a rotational force of the rotation driving mechanism, the switch link having a cylindrical member meshing with the worm, wherein the switch link has a link body extending vertically and one side of the link body is provided with the cylindrical member that protrudes from the link body;
- an inside handle lever cooperatively connected to an inside handle installed in a door of a vehicle;
- a release lever connected to a door catch and configured to lock or release the door catch;
- and
- a power child lever configured to selectively connect or separate the inside handle lever and the release lever by being moved by the switch link;
- wherein a lower end of the link body is provided with a pressing flange configured to press the power child lever and protruding in a direction opposite to the cylindrical member;
- wherein an upper portion of the power child lever is provided with an elliptical long hole into which a pin is inserted so that the power child lever is rotatable by means of the pin;
- wherein a lower portion of the power child lever is provided with a coupling protrusion;
- and
- wherein a rim of the long hole is pressed by the pressing flange, such that the power child lever is moved through the long hole with the pin inserted into the power child lever.
