Technology contents explanation and its utility model has the advantages that
Cardinal principle of the invention: change the screw diameter of threadlike body to change the actuation length of threadlike body, due to spiral
The change of object diameter will lead to the change of spiral part perimeter, and the change of each circumference of same helix can be superimposed, therefore can
Reach the technical effect for making subtle expanding-contracting action superposition amplification, this is for overcoming Electromagnetically actuated magnetic force to increase sharply with distance
Become smaller, fluid pressure actuated (air pressure, hydraulic) space more big-movement is slower, inverse piezoelectric effect actuating (one kind of electric actuation) stroke
The defect of small etc. the prior art has a very big significance；
If spiral number of turns are N；If Zhou Changwei T1, radius r1, diameter R1, spiral overall length before single turn helix radius change
For L1；If Zhou Changwei T2, radius r2, diameter R2, spiral overall length are L2 before single turn helix radius change；
Then there is formula: (1), Δ L=L2-L1=Δ T*N=(T2-T1) * N=2 π Δ r*N；
From the above equation, we can see that the displacement equations mode of spiral variable diameter is mainly related unrelated with quantity with circle number, so can lead to
Toning number of full circle N adjusts magnification ratio；
Assuming that being used for driving body of the invention using artificial-muscle of the invention, and it is (non-for driving body to set artificial-muscle
) helical orbit circle number M, set spiral overall length change as Δ L', radius change be Δ r'；
Then there is Δ L'=2 π Δ r'*M；
Use at least one artificial-muscle as driving body, since spiral is round, therefore can rough identification be mounted on
Drive the radius change size Δ r' of the spiral for the artificial-muscle that will lead under the displacement L ideal effect of intracorporal artificial-muscle
=Δ L/2 (there may be Δ r'=Δ L as the driving body of artificial-muscle of the invention using a plurality of artificial-muscle of the invention,
In order to which problem reduction does not do excessive description；)
Then have most: Δ L'=2 π Δ L/2*M；
Above formula, which substitutes into formula (1), then to be had: Δ L'=2 π Δ L/2*M=π * (2 π Δ r*N) * M=2 π 2* Δ r*N*M；
From the above, it can be seen that use artificial-muscle of the invention as driving body in artificial-muscle of the invention, adjustment parameter N,
M can obtain very big displacement equations multiple；
From the above, it can be seen that it is of the invention be in structure can with recursive structure (one word of recursive structure for the present inventor oneself definition
, it refers mainly to repeat nonlinear superposition design structure, recursive structure refers to multi-level (being more than or equal to 3 layers) in the present invention
Repeat ' using the threadlike body of low level artificial-muscle it is flexible come drive higher level artificial-muscle helical orbit change
Diameter ' design, constitute a displacement equations chain), so that the raising displacement equations multiple of great-jump-forward is (assuming that third layer helical orbit
Number is enclosed as B circle, then has the π 3* of Δ L "=2 Δ r*N*M*B, adjustment parameter N, M, B that can obtain very big displacement equations multiple)；
Above operation is in order to illustrate amplification factor of the invention is main and helical orbit circle number, iterative design number of plies phase
It closes, the understanding of reader will not be impacted calculating and a small amount of falsehood occur.
Vocabulary explanation.
' driving body ' refers to that the entity of driving helical orbit screw diameter variation, driving body can be element, device, can also
To be functional module, driving body may be with other devices or element common elements or structure, this is common situations in machinery；It drives
Kinetoplast is for example: filling a large amount of piezoelectric ceramics on a columnar shape basal surface, manipulates piezoelectric ceramics radially stretching in matrix；It is hollow
Inflatable elastic ball etc..
' threadlike body ' refers to thread, such as iron hoop chain, steel cable, spring etc., uses threadlike body Shi Yingjie of different nature
Close ' common knowledge ', ' prior art ', ' rudimentary knowledge ' use different designs, not violate that ' design one can be normal benign
Operation artificial-muscle ' technical purpose be deliberately set to cannot to run, such as: should be adopted using when flexible linear body
With actuating when increase helical orbit screw diameter mode, and the length of the slack of flexible linear body cannot be greater than actuating when
Contracted length, for another example: when using elastic threadlike body, it should be noted that threadlike body elastic force and stretching, extension span relationship avoid using as far as possible
Elastic force very little stretches span but very big elastic threadlike body, for another example: it should be noted that the strength of driving body variable diameter should overcome threadiness enough
The internal stress of body, so as not to occur because threadlike body intensity is too big and cause threadlike body spiral part can not variable diameter the case where, etc..
' helical orbit ', which refers to, can be limited to threadlike body the constant spiral entity of variable diameter hour circle number or by entity institute
The space path of limitation；Helical orbit can be element, device, cavity or slot with spiral shape, constitute helical orbit
Element, device may be with other devices or element common elements or structure, this is common situations in machinery field；Helical orbit ratio
Such as: the spiral-shaped, cylinder that slot is arranged in by helix tube, the helicla flute of periphery, the slotted element of multiple tools is intracorporal
Threaded hole etc., helical orbit can be multiple spiral, helical orbit can be on the whole it is curved, using when design because as far as possible
It avoids manufacturing helical orbit using flexible too strong material；It is worth noting that person trained in a certain field may attempt to design
Strange track evades the application, but as long as track of its design contains helical orbit, and threadlike body cooperates its track shape
Its track should then be regarded at spiral as helical orbit described herein；Since the variation of screw pitch will affect spiral overall length therefore this hair
Bright helical orbit avoid the spiral overall length variation weakening screw diameter generated by screw pitch variation from changing production as far as possible when designing
The case where raw spiral overall length changes；In the case where ignoring threadlike body completely, vision judges helical orbit of the invention up
Go may not be spiral shape (such as situation described in technology contents 6-8 be cooperation threadlike body winding after could visually
Obtain spiral shape), helical orbit of the invention is considered as helical orbit when designing or the spiral coil of threadlike body is upward in helical axis
Sliding problem, and be defined and prevent because the sliding of spiral coil causes the product designed cannot by rationally designing
Flexible situation.
' movement of helical orbit limitation threadlike body makes the movement of the particle on the spiral part of threadlike body predominantly along spiral
Partial helix sliding ' it is transported since the movement of the particle on the spiral part of threadlike body can have micro turn and radial direction
Dynamic, so ' main ' word is used to meet human language habit, ' main ' word should not be considered as by the reader of the application
Fuzzy sets.
' threadlike body a part is limited to spiral shape by helical orbit ' contains threadlike body in helical orbit space interior, line
Shape body is slidably coated on the connection relationship that track solid exterior etc. can be such that threadlike body is constrained by helical orbit.
' driving body drives the screw diameter of helical orbit flexible ' the i.e. variation of driving body driving screw diameter.
' telescoping tube ' refers to the pipe that length can passively change.
' dimension shape spring ' refers to that the spring for safeguarding telescoping tube shape, elastic force cannot be too big.
' maximum length of threadlike body ' refer to threadlike body can normal use when maximum length because some threadlike bodies are long
It is short variable, therefore have this restriction.
' spiral overall length ' i.e. spiral part expands into the total of the length of straight line after straight line namely each circumference of helical orbit
With.
' spiral ', the mankind accurately define spiral without perfection, and people even claim the camber line of a plurality of radial arrangement
For spiral, in order to guarantee the clear of definition, spiral of the invention is defined in: at least there is one not to be selfed the continuous of convolution completely
The path of point set or line-segment sets, wherein ' complete ' refers to that convolution is greater than or equal to 360 degree, such as spring, Archimedes spiral, electricity
The solenoid etc. of magnet, helical axis can be straight line (when helix tube is straight), curve (when helix tube is bent), helical curve (spiral
Pipe again spiral when be helix), the present invention in spiral include helix (axial multi-turn) path, vortex filament (radial multi-ring)
Path, taper helical path, variable-pitch propeller path, variable diameter helical path, multilayer helical path and other helical wire forms
Path and their combination may exist corner angle in spiral of the invention.
Beneficial effects of the present invention: structure is simple, economical and practical.
