Embodiment 1

[0024] see Figures 1 to 3 The shown embodiment 1 of the soft bionic finger of the present invention includes: a soft bionic finger, including: at least two knuckles 1 and a telescopic structure 2 for connecting the at least two knuckles 1 . The knuckle 1 is a hollow flexible tube body; the knuckle 1 communicates with the telescopic structure 2 to form a closed air cavity 10, and the telescopic structure 2 includes a linear bottom surface and a wave-shaped structure connecting the linear bottom surface, The wavy structure includes at least one crest and at least one trough, and the crest and trough are connected in sequence.

[0025] The soft bionic finger of the present invention connects the knuckles 1 by setting the telescopic structure 2, and uses the process of inflating and deflating the air cavity 10 in the telescopic structure 2 to generate bending. At the same time, due to the existence of the knuckles 1, a bionic finger similar to a human body is formed. As a result...

Abstract

The invention discloses a soft bionic finger. The soft bionic finger comprises at least two knuckles and a telescopic structure, wherein the knuckles are hollow flexible pipe bodies, the telescopic structure is used for connecting the at least two knuckles, the knuckles communicate with the interior of the telescopic structure to form a closed air cavity, the telescopic structure comprises a linear bottom surface and a wave-shaped structure connected with the linear bottom surface, the wave-shaped structure comprises at least one wave crest and at least one wave trough, and the wave crests andthe wave troughs are sequentially connected. According to the soft bionic finger, by arranging the telescopic structure, the knuckles are connected, the process of inflating and deflating the air cavity in the telescopic structure is utilized to generate bending, meanwhile, due to the existence of the knuckles, the bionic effect similar to fingers of a human body is formed, and compared with an existing scheme, the soft bionic finger is better close to a real human finger, has stronger grasping and pressing functions, and has better bionic performance.

Description

technical field [0001] The invention relates to the field of bionic machinery, in particular to a soft bionic finger and a bionic manipulator. Background technique [0002] At present, the manipulator based on human bionics has attracted attention because of its wide application. The core of the bionic manipulator is the bionic finger. Most of the bionic fingers on the market adopt a pneumatic multi-chamber structure. By inflating the gas chamber, the whole soft hand bends in a certain direction to realize the grasping function. As disclosed in Chinese invention patent CN 107378980 A, a new type of flexible finger includes a finger base and a finger surface, the finger surface is connected to one side of the finger base, and the elastic modulus of the finger base is greater than that of the finger. The elastic modulus of the surface, the finger surface includes a fingertip segment, a finger segment and a heel segment, and the finger segment includes at least one crest and a...
