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.

Speed reducer, joint assembly and electric pendulum

In some aspects, a speed reducer includes an inner gear having an inner gear hole; an outer gear having an outer gear hole, arranged in the inner gear hole and meshing with the inner gear; an eccentric wheel rotatably supported in the outer gear hole, the outer gear being driven by the eccentric wheel to revolve around the rotation axis of the eccentric wheel while rotating around its own axis; a brake block arranged on the eccentric wheel to rotate together with the eccentric wheel, the brake block being movable relative to the eccentric wheel between a braking position and a release position; an elastic member coupled to the eccentric wheel and the brake block, and configured to press the brake block towards the braking position; and a drive member coupled to the eccentric wheel, a rotation axis of the drive member being coaxial with the rotation axis of the eccentric wheel.
