Specific embodiment
Embodiments of the present invention is further illustrated with reference to the accompanying drawing:
As shown, a kind of bubble type bionic muscle unit comprising electrothermal piece 1 and with the electrothermal piece 1 seal wrap
The longitudinal fiber pipe 2 wrapped up in and be fixedly connected, be also enclosed between the electrothermal piece 1 and longitudinal fiber pipe 2 easily vaporize in high temperature and
In the liquid 3 that room temperature easily condenses, the longitudinal fiber pipe 2, which has, forms gaseous material 7 simultaneously in the liquid 3 vaporization
The first state and condense contraction in the liquid that lengthwise dimension shortens when expansion and width direction size is elongated
The second state that the size in length and width direction is restored automatically afterwards, the electrothermal piece 1 are connected to power supply by conducting wire, the liquid
State substance uses water, and the gaseous material 7 is vapor, and the electrothermal piece 1 electrothermal alloy piece good using heating effect is described
Longitudinal fiber pipe 2 using high expansion and contraction rubber tube or plastic tube, the fiber of tube wall using high-intensitive natural fiber or
Staple fibre, each bubble type bio-mechanism unit is by the way that electrothermal piece conduction, high temperature is transmitted to liquid water by electrothermal piece, and is made
It occurs vaporization and forms bubble, and longitudinal fiber pipe inner volume increases and expands, and promotes longitudinal fiber pipe that length direction occurs
The deformation of contraction and width direction elongation, is gradually intended to spherical shape, the contraction so total length of fibre pipe can shorten；
Wherein, the liquid that the present embodiment can also select other heating easily to vaporize, such as alcohol, but the characteristic of water
It is best suitable for requirement of the invention, while cost is minimum, the present embodiment under equal conditions, preferentially selects pure water, and electric heating closes
Gold plaque can quickly transmit heat, and heat transfer efficiency is good.
A kind of bubble type bionic muscle group comprising several bubble type bionic muscle beams 5 arranged side by side and use
In the biocompatible material 4 for wrapping up several bubble type bionic muscle beams 5, each bubble type bionic muscle beam 5
The bubble type bionic muscle unit for being sequentially connected and communicating along its length including several, the bubble type bionic muscle beam
The radial direction that several equidistant arrangements are arranged on the axial direction of 5 excircles tightens ring 6.The radial direction tightens ring 6 and is arranged every two
The junction of a bubble type mode muscle unit, after the liquid vaporization inside longitudinal fiber pipe, volume becomes larger, and has radial bundle
The position of tight ring will not be become larger by the radial constraint for tightening ring, although two radial directions tighten the change of the longitudinal fiber pipe volume between ring
Greatly, but length dimension but shortens.
Wherein, due to all being communicated between each muscle unit, even if the electrothermal piece in a muscle unit is sent out
Raw failure will not make the operational failure of entire muscle package.
In addition, bubble type is bionical as shown in Fig. 2, the both ends of bubble type bionic muscle beam are also connected with mechanical joint skeleton 9
The flexible mechanical joint skeleton that can all drive both ends occurs for muscle package in opposite directions or mutually from movement.
Electrical connection between the bubble type bionic muscle unit uses in parallel or in series, when the bubble type Bionic muscle
When electrical connection between meat unit uses in parallel, if a bubble type bionic muscle element failure, will not influence entire gas
The flexible work of bubble bionic muscle beam；
When electric connection mode is using connecting, have occupied space few, the simple advantage of structure.
Cooling-lubricant 8 is filled between each bubble type bionic muscle beam 5 in the biocompatible material 4, is reduced each
Friction between a muscle package, prolongs the service life.
Using having radially distensible fibre pipe, the fiber on the fibre pipe is distributed is in the biocompatible material 4
Mesh arrangement is distributed in longitudinal bar shaped, and when the bending of each bubble type bionic muscle group, biocompatible material is also followed
Deformation occurs；In addition, fibre pipe is not limited to select in mesh arrangement or in longitudinal bar shaped distribution, can also select other by
The pipe of the scalable deformation of external force；
Wherein, the radial direction tightens the inner wall that the biocompatible material integrally formed can also be arranged in ring.
The working principle of the embodiment of the present invention: after electrothermal alloy piece is powered, high temperature makes neighbouring liquid water that vapour occur rapidly
Change, generates the bubble of a large amount of vapor, as the quantity of bubble increases, the pressure in longitudinal fiber pipe is increased rapidly, and inside is opened
Begin to expand, there is the radial position for tightening ring not become larger by the radial constraint for tightening ring, the radial position for not tightening ring starts
To radial dilatation, the shape of longitudinal fiber pipe is gradually intended to spherical shape, and bubble type bionic muscle beam is linked to be string in multiple spherical shapes
Shape, two radial directions tighten the longitudinal fiber pipe volume between ring and although become larger, but length dimension but shortens, and realizes contraction
Function.
When exposed to external forces, a bubble type bionic muscle beam or bubble type bionic muscle group can be transferred through longitudinal fibre
The flexibility of dimension pipe bends deformation, and the size of curvature is directly proportional to the flexibility of longitudinal fiber pipe.
After power-off, vapor is condensed, and the pressure in longitudinal fiber pipe gradually becomes smaller, and radial contraction, longitudinal fiber occurs
Pipe is gradually recovered original shape, and length also restores original size, realizes the function of elongation.
Multiple bubble type bionic muscle beams are wrapped in biocompatible material, and biocompatible material follows each bubble type
Bionic muscle Shu Yiqi is flexible and expansion, built-in lubricating fluid can be reduced effectively between each bubble type bionic muscle beam
Friction, prolongs the service life.
The present invention can be applicable to biological field and machinery field, and being assembled into will be bionical based on the microcosmic muscular movement of biology
The bionic mechanical hand that muscle is combined with joint makes it possible that human body or robot crawl and operation object, the present invention are gone back
The driving source that can connect integrated simulation signal more becomes while being able to satisfy crawl object using bionic mechanical hand of the invention
To in mildness, imitation biochemistry, by the flexible movement to realize finger of Electric control bionic muscle, to copy skeletal muscle movement
Mode operate, power and torque that outside generates cause the bending of meat fiber, the electric current letter in bionic mechanical hand whole system
Number and digital signal mutually convert, to greatest extent realize finger it is integrated, modularization and flexibility.
Embodiment is not construed as the limitation to invention, but any based on spiritual improvements introduced of the invention, all Ying Ben
Within the protection scope of invention.
