Abstract

A sliding door locking device of a vehicle may include a rail mounted to a vehicle body along a length direction thereof, a slider inserted in and slidably coupled to the rail, a connection structure of which one end is relatively rotatably coupled to the slider and another end is coupled to a door of the vehicle to slidably support the door of the vehicle, a latch rotatably mounted to the slider to lock the connection structure to the rail or release the connection structure from the rail, and a locking groove formed in the rail and to which the latch is detachable therefrom.

First claim

What is claimed is:

1. A sliding door locking device of a vehicle, comprising:
a main rail mounted to a vehicle body along a length direction of the vehicle body;
a slider inserted in and slidably coupled to the main rail;
a connection structure having a first end relatively rotatably coupled to the slider and a second end coupled to a door of the vehicle to slidably support the door of the vehicle;
a latch rotatably mounted to the slider to selectively lock the connection structure to the main rail; and
a concave locking groove formed in the main rail,
wherein the latch is removable from the concave locking groove after the latch is disposed in the groove,
wherein the main rail comprises:
a middle rail provided at a center of the main rail in a height direction of the main rail;
a first upper end rail provided at a position higher than the middle rail;
a second upper end rail provided at a position higher than the first upper end rail;

and a lower end rail provided at a position lower than the middle rail, and
wherein the concave locking groove is formed in a portion of the first upper end rail along a length direction of the first upper end rail.

2. The sliding door locking device of claim 1 , wherein the connection structure comprises a swing arm, and the latch is removed from the concave locking groove by rotation of the swing arm.

3. The sliding door locking device of claim 2 , wherein the swing arm comprises:
a swing arm body;
an operation protrusion integrally protruding from the swing arm body and forming a predetermined angle with respect to the swing arm body;
an upper end rail roller mounted to a front end of the operation protrusion and being inserted into and rolling in the second upper end rail when the door is moved from a closed position to a fully open position; and
a return spring providing an elastic restoring force to the swing arm.

4. The sliding door locking device of claim 3 , wherein an operation surface, for rotating the latch, is formed on the operation protrusion.

5. The sliding door locking device of claim 4 , wherein the latch comprises:
a latch body rotatably mounted to the slider;
a hook formed at a first end of the latch body; and
a pressure protrusion protruding from the latch body at a second end of the latch body opposite to the first end of the latch body, and the pressure protrusion being pressed by the operation surface of the operation protrusion of the swing arm by the rotation of the swing arm.
