pivot

Abstract

A rotating shaft includes a base, a rotating unit, and a rotating foot pad. The rotating unit includes a rotating member and a connecting protrusion. The rotating member is disposed on the base and is rotatable relative to the base about a first rotation axis parallel to a lateral direction between a first position and a second position. The connecting protrusion is linked to the rotating member and is rotatable relative to the base about a second rotation axis parallel to the lateral direction. The rotating foot pad is pivotally disposed on the base and is rotatable relative to the base about a third rotation axis parallel to the lateral direction between a retracted position and an upright position. The rotating foot pad has a recessed rail formed at one end along the lateral direction, a foot pad body at the other end, and a pivot portion located between the recessed rail and the foot pad body and pivotally connected to the base. The connecting protrusion of the rotating unit is slidably disposed within the recessed rail.

Claims

1. A rotating shaft, comprising: a base; a rotating unit including a rotating member and a connecting protrusion, the rotating member being disposed on the base and rotatable relative to the base about a first rotation axis parallel to a lateral direction between a first position and a second position, the connecting protrusion being linked to the rotating member and rotatable relative to the base about a second rotation axis parallel to the lateral direction; and a rotating foot pad being pivotally disposed on the base and rotatable relative to the base about a third rotation axis parallel to the lateral direction between a retracted position and an upright position, the rotating foot pad having a recessed rail formed at one end and recessed along the lateral direction, a foot pad body at the other end, and a pivot portion located between the recessed rail and the foot pad body and pivotally connected to the base, the connecting protrusion of the rotating unit being slidably disposed within the recessed rail; When the rotating component is in the first position, the rotating foot pad is in the retracted position, and the foot pad body of the rotating foot pad is relatively close to the base; when the rotating component rotates to the second position, the rotating foot pad is driven to rotate to the upright position through the connecting protrusion, and the foot pad body of the rotating foot pad is relatively away from the base.

2. The shaft as described in claim 1, wherein, During the rotation of the rotating component relative to the base between the first position and the second position, it also passes through a transition position. The concave rail has a connected drive rail portion and an arc-shaped rail portion. When the rotating component is in the first position, the connecting protrusion is located at the junction of the drive rail portion and the arc-shaped rail portion, and the rotating foot pad is located in the retracted position. When the rotating component rotates from the first position to the transition position, the connecting protrusion slides towards the drive rail portion and returns to the junction of the drive rail portion and the arc-shaped rail portion, driving the rotating foot pad to rotate to the supported position. When the rotating component rotates from the transition position to the second position, the connecting protrusion slides along the arc-shaped rail portion, and the rotating foot pad does not rotate.

3. The shaft as described in claim 2, wherein, The drive rail is straight and tangent to the curved rail.

4. The shaft as described in claim 1, wherein, The rotating unit also includes a cam member that is linked to the rotating member and can rotate relative to the base about the second rotation axis. The cam member has a connecting protrusion located at the protrusion.

5. The shaft as described in claim 4, wherein, The rotating unit also includes a drive gear sleeved on the rotating component and rotating synchronously with the rotating component, the drive gear meshing with the cam component.

6. The shaft as described in claim 1, wherein, The rotating foot pad has a first foot pad portion relatively close to the pivot portion and a second foot pad portion relatively far from the pivot portion; when the rotating foot pad is in the retracted position, the position of the first foot pad portion is lower than that of the second foot pad portion; when the rotating foot pad is in the upright position, the position of the second foot pad portion is lower than that of the first foot pad portion.
