Abstract
The invention relates to a self-regulation vibration reduction tennis racket. The tennis racket comprises a racket frame, racket surfaces and a racket bar, wherein two sides at the lower part of the racket frame are respectively connected with the racket bar through racket throat bars, and a transitional position between the racket frame and the racket bar is a racket throat; and vibration reduction regulation sleeves are respectively sleeved on the racket throat bars at two sides of the racket throat position and comprise an outer interlayer and an inner interlayer, respectively, and more than one layer of shear thickening material is arranged between the outer interlayer and the inner interlayer. When a tennis ball is struck, the tennis racket can absorb an impact force to generate a better vibration reduction effect, release soft sense of touch and better hand feel when the racket is slowly swung in chipping or playing a short ball and remarkably improve the rigidity of the racket when people swing at high speed to strike the ball, and the rigid racket frame can provide stronger striking force.
Description
Technical field
The invention belongs to the sports goods technical field, be specifically related to a kind of tennis racket.
Background technology
Square stance in the tennis is because ball speed is very fast, and the weight ratio of tennis itself is bigger, can produce moment enormous impact strength to tennis racket, continues to be easy to generate the athletic injury to elbow etc. for a long time.Therefore, the impact that needs tennis racket can bear the high speed spheroid, and reduce or avoid vibration, advantage such as good tennis racket need possess light weight, rigidity elasticity has both and absorbing power is strong at square stance.
Shear thickening materials is a kind of novel intelligent material, comprises shear thickening liquid and shear thickening gel etc.Under normal conditions, this material is very soft, in case run into collision or extruding at a high speed, the hard digestion external force thereby material becomes.After external force disappeared, material can be returned to its initial soft condition, the ability that it has extremely strong absorption to impact.
At present, the effectiveness in vibration suppression of existing tennis racket is still limited, and the impulsive force of batting still can reach sportsman's positions such as elbow.In addition, existing tennis racket often rigidity elasticity is fixing, can't regulate at any time according to sportsman's needs.Therefore be badly in need of developing the more comfortable self-regulation vibration damping tennis racket that meets above-mentioned requirements, the comfortableness that raising is used and handling.It is better that the tennis racket of use shear thickening materials is compared effectiveness in vibration suppression with traditional tennis racket, and can experience sportsman's demand and adapt to rigidity and the elasticity that its demand is regulated racket.
Summary of the invention
In order to solve the weak point of existing tennis racket, the invention provides a kind of good damping result, can be according to the flexible tennis racket of sportsman's demand self-regulation rigidity.
The technical solution that realizes above-mentioned purpose is as follows:
Self-regulation vibration damping tennis racket comprises frame, face and dabber, and the intermediate location between frame and the dabber is for clapping larynx, and both sides, frame bottom connect dabber by clapping larynx bar 1 respectively; Be arranged with vibration damping regulating sleeve 2 respectively on the bat larynx bar 1 of described bat both sides, throat position, described vibration damping regulating sleeve 2 comprises outer interlayer 3 and internal portioning layer 7, is the above shear thickening materials of one deck between outer interlayer 3 and the internal portioning layer 7.
Described shear thickening materials is shear thickening gel or the fabric fibre that contains shear thickening liquid.
Described outer interlayer 3 is identical with internal portioning layer 7 materials, is non-leakage material; Between outer interlayer 3 and the internal portioning layer 7 two layers of fabric fibre 6 that contains shear thickening liquid, be provided with shear thickening liquid layer 5 between the adjacent fabric fibre 6 that contains shear thickening liquid, be provided with shear thickening liquid layer 5 between the fabric fibre 6 of shear thickening liquid and adjacent outer interlayer 3 or the internal portioning layer 7.
The wall thickness of described vibration damping regulating sleeve 2 is the 4-6 millimeter, and length is the 60-110 millimeter.
Use the self-regulation vibration damping tennis racket of shear thickening materials, utilized under the shear thickening liquid material normality soft, run into high speed impact and become hard and then digestion external force, and, tennis racket is made correspondingly at the each square stance of sportsman adjusted along with applied shock change material intensity changes thereupon.
Useful technique effect of the present invention is embodied in following several aspect:
1, good damping result: shear thickening materials has extremely strong absorption impact capacity, uses the tennis racket of this material can absorb impulsive force at square stance and produces better effectiveness in vibration suppression;
2, rigidity elasticity flexible modulation: because the shear thickening behavior of shear thickening materials, make the tennis racket that uses this material cut or get the short ball and to discharge soft sense of touch and better feel when swinging the bat at a slow speed; And can increase the rigidity of racket significantly at the square stance of swinging the bat at a high speed, hard frame can provide bigger striking force.

Fig. 2 is the A-A profile of Fig. 1,
Fig. 3 is a trilaminate material vibration damping regulating sleeve cutaway view.
Fig. 4 is a multilayer material vibration damping regulating sleeve cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is done to describe further by embodiment.
Embodiment 1:
Referring to Fig. 1 and Fig. 2, self-regulation vibration damping tennis racket comprises tennis racket, and tennis racket comprises frame, face and dabber, and both sides, frame bottom connect dabber by clapping larynx bar 1 respectively, and the intermediate location between frame and the dabber is for clapping larynx.Be respectively installed with vibration damping regulating sleeve 2 on the bat larynx bar 1 of bat both sides, throat position.Vibration damping regulating sleeve 2 comprises outer interlayer 3 and internal portioning layer 7, is one deck shear thickening gel 4 between outer interlayer 3 and the internal portioning layer 7, sees Fig. 3.Outer interlayer 3 is identical with internal portioning layer 7 materials, is non-leakage material, and the wall thickness of vibration damping regulating sleeve 2 is 4 millimeters, and length is 60 millimeters.
When using the tennis racket of the present invention square stance of slowly swinging the bat, the shear thickening materials of vibration damping regulating sleeve 2 inside is in than soft condition, offers better sense of touch of sportsman and feel, the trend of place kick more accurately; When using the tennis racket of the present invention square stance of swinging the bat at a high speed, the shear thickening materials of vibration damping regulating sleeve 2 inside is violently shaken, and hardening rapidly offers the bigger striking force of sportsman, can get the more winning ball of high-quality.Simultaneously, using tennis racket square stance of the present invention,, can reduce the impact that is delivered to elbow etc., better effectiveness in vibration suppression is being provided because the shear thickening materials of vibration damping regulating sleeve 2 inside has extremely strong absorption impact capacity.
Embodiment 2:
Referring to Fig. 4, between outer interlayer 3 and the internal portioning layer 7 two layers of fabric fibre 6 that contains shear thickening liquid, be provided with shear thickening liquid layer 5 between the adjacent fabric fibre 6 that contains shear thickening liquid, be provided with shear thickening liquid layer 5 between the fabric fibre 6 of every layer of shear thickening liquid and adjacent outer interlayer 3 or the internal portioning layer 7.The wall thickness of vibration damping regulating sleeve 2 is 6 millimeters, and length is 110 millimeters.
Other structure is with embodiment 1.
