Abstract

The invention belongs to the technical field of robots, and relates to a finger structure and a robot. In the finger structure, a proximal phalanx shell, a middle phalanx shell, a distal phalanx shelland a connecting rod form a four-rod mechanism, the proximal phalanx shell serves as a fixing frame, a driving assembly drives the middle phalanx shell to swing, the distal phalanx shell is in linkage with the connecting rod, the distal phalanx shell swings in the swinging direction of the middle phalanx shell, and the finger structure is integrally bent and straightened. The connecting rod is arranged to be a first bent section, and a notch of the first bent section faces the back face of the middle phalanx shell. When the finger structure is straightened, namely the distal phalanx shell isflush with the middle phalanx shell, the inner wall of the first near end at a distal phalanx opening extends into the bottom of the notch of the first bent section, so that the inner wall of the first near end can be closer to the center of the distal phalanx opening. The far finger opening of the finger structure can be manufactured to be small, and the integrity of the appearance of the distalphalanx shell is improved. Due to the existence of the first bent section of the connecting rod, when the distal phalanx shell is impacted, the connecting rod shows certain elasticity and absorbs theimpact.

Description

technical field [0001] The present application belongs to the technical field of robots, 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 the...
