Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Embodiment one
Referring to Fig.1-2, a kind of operation body-building bar for arm strength building, including two handles 1, handle 1 are equipped with anti-skid chequer, prevent from being good for
When body, palm skids, and reduces body-building effect, two opposite both ends of handle 1 are fixedly connected with lanyard, facilitate bar for arm strength building hanging over wall
On.
Two 1 opposite sides of handle are fixedly connected to a bourdon tube 2, and two 2 opposite sides of bourdon tube are fixedly connected
At 6 both ends of elastomer, 2 inner surface of bourdon tube, which is sealedly and fixedly connected, insulating layer 3, and insulating layer 3 is made of rubber insulation material.
3 inner surface opposite sides of insulating layer is fixedly connected there are two conductive layer 4, and sealed envelope has ER fluid obturator
5, ER fluid obturator 5 is made of ER fluid, and ER fluid is a kind of suspension at typical condition, by with high dielectric
The solia particle of constant, which is dispersed in the insulating oil of low-k, to be formed, and liquid can occurs extremely under the action of electric field in it
Solid transformation, and in a certain range with the reinforcement of electric field, shear yield strength is continuously increased.
To increase the difficulty of bending, it is equivalent to the coefficient of elasticity for improving bourdon tube 2, expands whole elastic force stress model
It encloses；If wrong power occurs at this time, bourdon tube 2 will be sprung back, but ER fluid obturator 5 has no rebound characteristics, and powerful cuts
Shearing stress becomes the resistance that bourdon tube 2 is sprung back, to force bourdon tube 2 that can only slowly restore to the original state state, effectively increases safety
Property.
ER fluid obturator 5 is electrically connected there are two conductive layer 4,6 inner circumferential side of elastomer be fixedly connected with piezoelectric board 7 and
Inside is equipped with amplifying device 8, and 6 inner circumferential side of elastomer offers annular slot 61, and 61 internal clearance of annular slot is combined with piezoelectricity
Plate 7, when elastomer 6 is compressed or stretched, annular slot 61 is only capable of passing to compressive state into piezoelectric board 7, so that pressure
Battery plate 7 both will not be compressed or be stretched.
Piezoelectric board 7 is made of piezoelectric ceramics, and the mechanism of piezoelectric effect is: the crystal symmetry with piezoelectricity is lower,
When by external force, deformation occurs, the relative displacement of negative ions is overlapped positive and negative charge center no longer in structure cell, causes
Macroscopic polarization occurs for crystal, and plane of crystal surface density of charge is equal to projection of the polarization intensity on surface normal, so piezoelectricity
Both ends of the surface will appear heterocharge when material compression power acts on deformation, to generate voltage.
Piezoelectric board 7 is electrically connected at 8 input terminal of amplifying device, and amplifying device 8 is made of voltage amplifier circuit, cooperation auxiliary
The voltage that battery 9 inputs piezoelectric board 7 amplifies, to reach the voltage for driving ER fluid obturator 5 to undergo phase transition enough
Intensity, 8 output end of amplifying device are electrically connected there are two conductive layer 4, and boosting battery 9 is mounted in handle 1.
When elastomer 6 is oppressed by the bourdon tube 2 that bends, the piezoelectric board 7 elastomer 6 inside is made to generate deformation and then generation
Piezoelectric effect, under the action of amplifying device 8 and boosting battery 9, the voltage generated to piezoelectric board 7 is amplified, and is passed through later
Conductive layer 4 applies some strength electric field force to ER fluid obturator 5.
Now the working principle of the embodiment of the present invention one is done described below:
Firstly, both hands hold two handles 1 when taking exercise, bending bourdon tube 2 is opened up, the bourdon tube 2 of bending oppresses elasticity
Body 6 makes elastomer 6 that local deformation occur, and the piezoelectric board 7 for causing it internal generates deformation and then causes the piezoelectricity effect of piezoelectric board 7
It answers, 7 both ends of piezoelectric board externally generate voltage, under the action of amplifying device 8 and boosting battery 9, to the voltage of the generation of piezoelectric board 7
It amplifies, 8 output end of amplifying device applies some strength electric field force to ER fluid obturator 5 by conductive layer 4, in electric field
Under the action of ER fluid obturator 5 liquid can occur to solid transformation, and in a certain range with the reinforcement of electric field,
Its shear yield strength is continuously increased, to increase the difficulty of bending, is equivalent to the coefficient of elasticity for improving bourdon tube 2, is expanded
Big entirety elastic force field of load；If wrong power occurs at this time, bourdon tube 2 will be sprung back, but ER fluid obturator 5 has no rebound
Characteristic, powerful shear stress become the resistance that bourdon tube 2 is sprung back, thus force bourdon tube 2 that can only slowly restore to the original state state,
Safety is effectively increased, avoiding bourdon tube 2 with fixed handle 1, quickly rebound causes to sprain one's wrist or wounds oneself.
Embodiment two
Referring to Fig. 3-4 compared to embodiment one, only following different, two opposite one end of handle 1 offer pulling force handle
11, it is used for hands grasping, carries out stretching.
6 inner circumferential side both ends of elastomer are fixedly connected with multiple limited posts 62, and 7 both ends of piezoelectric board are fixedly connected with fixed plate
71, multiple limit holes 72 are offered in fixed plate 71, multiple limit holes 72, which correspond clearance fits, limited post 62, makes
Tensile deformation can occur for piezoelectric board 7.
Now the working principle of the embodiment of the present invention two is done described below:
Firstly, hands grasping pulling force handle 11, carries out stretching, pulling force handle 11 is pulled open opposite to each other, with embodiment one
Identical, after the stretch, piezoelectric effect, the final shear stress for improving ER fluid obturator 5, to increase occur for piezoelectric board 7
The difficulty stretched is equivalent to the coefficient of elasticity that improves bourdon tube 2, expands whole elastic force field of load；If losing at this time
Power, bourdon tube 2 will be sprung back, but ER fluid obturator 5 has no rebound characteristics, and powerful shear stress becomes bourdon tube
The resistances of 2 rebounds effectively increase safety, avoid 2 band of bourdon tube to force bourdon tube 2 that can only slowly restore to the original state state
Quickly rebound wounds oneself to fixed handle 1.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
