AI Technical Summary
Traditional mechanical transmission systems consume a lot of energy and have high drive costs in scenarios such as heavy photovoltaic panels, radar antenna pitch adjustment, and robotic arm end effector rotation. They also lack an effective load balancing mechanism, which leads to reduced equipment life and energy waste.
Design an energy storage and assist device that utilizes a combination of cam assembly and elastic element. The rotation of the cam assembly drives the traction element to wind and store elastic potential energy, providing auxiliary torque to drive loads such as photovoltaic panels, thereby reducing reliance on motors.
It improves system energy efficiency, reduces drive energy consumption, enhances equipment stability and reliability, reduces energy loss in transmission links, and optimizes space utilization.
