Abstract

The invention belongs to the technical field of robot parts, and relates to a finger structure and a robot. In the finger structure, a near knuckle shell, a middle knuckle shell, a far knuckle shell and a connecting rod form a four-bar mechanism, the near knuckle shell is taken as a fixing frame, a driving assembly drives the middle knuckle shell to swing, the far knuckle shell is linked with theconnecting rod, the far knuckle shell swings in the swinging direction of the middle knuckle shell, and whole bending and straightening action of the finger structure is achieved. A transmission rod is provided with a first bending arm, and a notch of the first bending arm faces the back surface of the near knuckle shell. When the finger structure is straightened, in other words, the near knuckleshell is flush with the middle knuckle shell, and the inner wall of the near end of the middle knuckle extends into the bottom of the notch of the first bending arm, so that the inner wall of the nearend of the middle knuckle can be closer to the central position of a near end opening. The near end opening of the finger structure can be made relatively small, so that the integrality of the appearance of the middle finger shell is improved. Due to the fact that the transmission rod is provided with the first bending arm, when the far knuckle shell or the middle knuckle shell is impacted, the transmission rod can exhibit elasticity and absorb 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...
