Abstract
A joint assembly includes a speed reducer and a motor. The speed reducer includes a housing, an internal gear; an external gear at least partially arranged in an internal gear hole of the internal gear and meshing with the internal gear; an eccentric wheel rotatably and at least partially arranged in an external gear hole of the external gear; a limiting disc; and a drive member. A rotation axis of the eccentric wheel is coaxial with a central axis of the internal gear. The eccentric wheel drives the external gear to revolve around the rotation axis of the eccentric wheel. The drive member is driven to rotate by the motor. The drive member drives the eccentric wheel to rotate and hence drives the external gear to revolve around the rotation axis of the eccentric wheel in the internal gear hole of the internal gear, driving the internal gear to rotate.
