The application belongs to the technical field of robot accessories, and relates to a joint energy storage booster mechanism, a robot joint structure and a robot. In the joint energy storage booster mechanism, one end of the sleeve is used as the first pivot end, the transmission rod can slide axially relative to the slide bar and one end of the transmission rod is used as the second pivot end, and the elastic structure is arranged between the slide rod and the sleeve. Between, the switching device can make the transmission rod switch between the fixed state and the free state. When the joint needs to store energy, the transmission rod is switched to a fixed state, and the sliding rod follows the movement of the transmission rod, and the kinetic energy of the sliding rod is converted into the potential energy of the elastic structure to realize energy storage. When the transmission rod and the sliding rod return, the elastic structure releases energy to drive the transmission rod and the sliding rod to move in reverse, and play an auxiliary role in promoting the movable arm. When the transmission rod is switched to a free state, the transmission rod can slide relative to the sliding rod, and the elastic structure cannot store energy. The joint energy storage booster mechanism, the robot joint structure and the robot can realize energy storage and energy release by timely escapement of the transmission rod.
Description
technical field [0001] The application belongs to the technical field of robot accessories, and in particular relates to a joint energy storage booster mechanism, a robot joint structure and a robot. Background technique [0002] At present, there are two problems in the motion process of the robot joint structure: 1. In some specific motions, large speed and acceleration are required, and the output power of the required rotating power parts needs to be increased accordingly, which will increase the overall performance of the joint. Mass and volume, and production cost; 2. At a specific position, the gravitational potential energy of the robot joint structure cannot be stored, and it is necessary to rotate the dynamic parts to overcome the gravity to do work, resulting in energy loss. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a joint energy storage booster mechanism, a robot joint structure and a robot to so...
