Description
Technical field
The invention belongs to marmem applied technical field, and in particular to a kind of shape memory alloy wire material Wound-rotor type
Drive mechanism.
Background technology
Legacy drive is driven using electric system, complicated, and volume is big, and cost is high, is also easy to produce electromagnetic interference, and it should
It is very limited with field.Marmen is typically to utilize the heated shape restored of marmem
Memory effect, which is produced, replys displacement and restoring force, externally does work to realize the purpose of driving, is made an uproar with simple in construction, reliable, nothing
Sound, the advantage without electromagnetic interference.In current marmem, shape-memory properties preferably Ultimum Ti, its is optimal
Recovery strain is about 8%, but in actual applications, its recovery strain is about 5~6%, if needing 100,000 in view of driver
It is secondary that recovery strain is generally designed as 2~4% to secondary driving and mechanism reliabilities repeatedly up to a million, briefly, 100mm length
It is 2~4mm that the reply that the shape memory alloy wire material of degree is heated after deforming when replying, which is moved, therefore, when drive mechanism needs are larger
Drive displacement when, shape memory alloy wire material length it is also longer, it is necessary to space it is larger.If can be from structure design, smaller
Space in, shape memory alloy wire material can have larger drive displacement, by the design of marmen and
In the application of industry, there is very great meaning.
The content of the invention
The shape of big drive displacement is realized in less space the invention provides a kind of shape memory alloy wire material
Memorial alloy silk material Wound-rotor type drive mechanism.
Technical scheme is as follows
A kind of shape memory alloy wire material Wound-rotor type drive mechanism, including panel 1, several pulleys for being fixed on panel 1
2nd, the fixing end 3 being fixed on panel 1, the displacement output end 4 being fixed on panel 1, one end are fixed on the other end of panel 1 and fixed
The shape memory alloy wire material 6 that the extension spring 5 of shifter output terminal 4 in place and mechanical training are crossed；The one end of shape memory alloy wire material 6 is fixed
In fixing end 3, several pulleys 2 are bypassed with winding mode, the other end is connected with displacement output end 4.
The coiling form of shape memory alloy wire material 6 can be arc-shape winding or be polygon coiling or for turn back around
Line is levels coiling.
The quantity of the pulley is no less than 2
The fixed end of displacement output end 4 on panel, can straight line move freely.
It is an advantage of the invention that：This structure realizes that shape memory alloy wire material exports big driving position in less space
Move, present invention miniaturization simple and reliable for structure can be applied extensively in mechano-electronic model, on the industrial circle such as automation.

Embodiment
With reference to the accompanying drawings and examples, the present invention is described in further detail,
Embodiment 1. is as shown in Figure 1
Embodiment 2. is as shown in Figure 2
Embodiment 3. is as shown in Figure 3
The course of work of the shape memory alloy wire material Wound-rotor type drive mechanism is as follows：
Tensile pre-deformation is carried out to shape memory alloy wire material 6, and carries out mechanical training.
Assembled as shown in Fig. 1 or Fig. 2 or Fig. 3, fixing end 3, displacement output end 4 are connected with external power source, using electricity
Stream heating makes shape memory alloy wire material recovery of shape.
Electrified regulation, shape memory alloy wire material 6 occur reply shrink, by pulley 2 by shape memory alloy wire material 6 around
The reply displacement for crossing the different broken lines of pulley 2 passes to displacement output end 4 very well, realizes that displacement is exported.
Cut off the electricity supply, the natural cooling of shape memory alloy wire material 6, under the effect of extension spring 5, the quilt of shape memory alloy wire material 6
Elongate, shape returns to original state.
It is described above, the simply preferably embodiment of the present invention, but protection scope of the present invention is not limited to
This, any one skilled in the art in the technical scope of the exposure of the present invention, the change that can readily occur in or
Replace, should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be with the protection of claim
Scope is defined.
