Abstract

A running board device comprises a stationary running board; a retractable running board apparatus comprising a retractable mechanism moveable between a stretched position and a retracted position and a retractable running board mounted to the retractable mechanism, wherein at the stretched position, at least a part of the retractable running board stretches out below the stationary running board and beyond the stationary running board, and at the retracted position, the retractable running board is retracted into below the stationary running board.

First claim

What is claimed is:

1. A vehicle comprising:
a vehicle body and a vehicle door; and
a running board device comprising:
a stationary running board; and
a retractable running board apparatus comprising a retractable mechanism that is moveable between a stretched position and a retracted position and a retractable running board mounted to the retractable mechanism,
wherein at the stretched position, at least a part of the retractable running board stretches out below the stationary running board and beyond the stationary running board, and at the retracted position, the retractable running board is retracted into below the stationary running board,
wherein the retractable mechanism comprises:
a mounting support;
a running board support;
a limb assembly comprising a first limb, a second limb and a third limb, wherein a first end of the first limb is pivotally connected to the mounting support, a second end of the first limb is pivotally connected to the running board support, a first end of the second limb is pivotally connected to the mounting support, a first end of the third limb is pivotally connected to a second end of the second limb, and a second end of the third limb is pivotally connected to the running board support;
a trajectory controlling plate mounted to the first limb and comprising a trajectory controlling groove; and
a trajectory controlling shaft having a first end inserted into the trajectory controlling groove and movable in the trajectory controlling groove, and a second end mounted to at least one of the second limb and the third limb,
wherein the stationary running board and the retractable mechanism are mounted to the vehicle body separately.

2. A vehicle comprising:
a vehicle body and a vehicle door; and
a running board device comprising:
a stationary running board; and
a retractable running board apparatus comprising a retractable mechanism that is moveable between a stretched position and a retracted position and a retractable running board mounted to the retractable mechanism,
wherein at the stretched position, at least a part of the retractable running board stretches out below the stationary running board and beyond the stationary running board, and at the retracted position, the retractable running board is retracted into below the stationary running board,
wherein the retractable mechanism comprises:
a mounting support;
a running board support;
a limb assembly comprising a first limb, a second limb and a third limb, in which a first end of the first limb is pivotally connected to the mounting support, a second end of the first limb is pivotally connected to the running board support, a first end of the second limb is pivotally connected to the mounting support, a first end of the third limb is pivotally connected to a second end of the second limb, and a second end of the third limb is pivotally connected to the running board support;
a trajectory controlling rod having a first end pivotally mounted to the first limb; and
a trajectory controlling shaft having a first end pivotally connected to a second end of the trajectory controlling rod and a second end mounted to at least one of the second limb and the third limb,
wherein the stationary running board and the retractable mechanism are mounted to the vehicle body separately.

3. The vehicle as set forth in claim 1 , wherein a groove is disposed in a lower surface of the stationary running board, and at the retracted position, at least a part of the retractable running board is accommodated in the groove.

4. The vehicle as set forth in claim 3 , wherein at the retracted position, a front surface of the retractable running board is fitted to a front surface of the groove, and a top face of the retractable running board is fitted to a top face of the groove.

5. The vehicle as set forth in claim 3 , wherein a top face of the groove is inclined upwardly along a direction from the inside to the outside.

6. The vehicle as set forth in claim 2 , wherein a groove is disposed in a lower surface of the stationary running board, and at the retracted position, at least a part of the retractable running board is accommodated in the groove.

7. The vehicle as set forth in claim 6 , wherein at the retracted position, a front surface of the retractable running board is fitted to a front surface of the groove, and a top face of the retractable running board is fitted to a top face of the groove.

8. The vehicle as set forth in claim 6 , wherein a top face of the groove is inclined upwardly along a direction from the inside to the outside.
