Abstract

The application belongs to the technical field of robot components, and relates to finger structures and robots. In this finger structure, the proximal knuckle shell, the middle knuckle shell, the distal knuckle shell and the connecting rod constitute a four-bar mechanism, the proximal knuckle shell is used as a fixed frame, the driving component drives the middle knuckle shell to swing, and the distal knuckle shell is linked with the connecting rod , the far knuckle shell follows the swing direction of the middle knuckle shell to realize the overall bending and straightening of the finger structure. The transmission rod is arranged as a first bending arm, and the notch of the first bending arm faces the back of the proximal knuckle shell. When the structure of the finger is straightened, that is, the shell of the proximal knuckle is flush with the shell of the middle phalanx, and the inner wall of the proximal end of the middle phalanx extends into the bottom of the notch of the first bending arm, so that the inner wall of the proximal end of the middle phalanx can be closer to the center of the proximal opening . The proximal opening of the finger structure of the present application can be made relatively small, so that the integrity of the appearance of the middle knuckle shell is improved. Because the transmission rod has the existence of the first bending arm, when the far knuckle shell or the middle knuckle shell is impacted, the transmission rod will show elasticity and absorb the impact.

Description

technical field [0001] The application belongs to the technical field of robot components, and in particular relates to a finger structure and a robot. Background technique [0002] At present, the finger structure of the robot is usually provided with a connecting rod between two adjacent knuckle shells, and the two ends of the connecting rod are respectively connected to the two knuckle shells, so as to realize the transmission of the two knuckle shells. Due to the existence of the connecting rod, the knuckle case should be provided with a relatively large opening for the connecting rod to pass through, that is, the knuckle case will be cut a lot, which will make the appearance of the knuckle case less complete. In addition, since the connecting rod belongs to a one-degree-of-freedom system, when the finger structure is impacted, it is difficult for the connecting rod to exhibit certain elasticity to absorb the impact. Contents of the invention [0003] The purpose of t...
