1. A seat five-link structure, comprising:
a bottom support, a wall plate, a first front link, a second front link and a rear link, wherein the bottom support is pivotally connected with the first front link through a first pivot axis, the first front link is pivotally connected with the second front link, the second front link is pivotally connected with the wall plate, and the rear link is pivotally connected with the bottom support through a second pivot axis and is pivotally connected with the wall plate;
a first electric motor configured to output a first external force for driving the first front link to rotate around the first pivot axis;
a second electric motor configured to output a second external force for driving the rear link to rotate around the second pivot axis; and
an angle adjuster and a star-shaped rod, wherein the first front link is rotatably mounted to the bottom support through the angle adjuster, wherein the star-shaped rod extends through and cooperates with the angle adjuster, wherein the star-shaped rod is drivable by the first electric motor, wherein an axis of the star-shaped rod defines the first pivot axis.
