Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1, the piezoelectricity boxing dynamometry target that first embodiment of the invention provides comprises target body 102, man machine operation interface 101 and fastening astragal.Man machine operation interface 101 receives the piezoelectric signal of target body 102 and carries out data processing, and fastening astragal is for being fixed on thing to be boxed by target body 102, and target body 102 is fixed on this fastening astragal.
One end of this fastening astragal is provided with VELCRO circle hair side 105, and the other end is provided with and can stings hair side 106 with VELCRO circle hair side 105 VELCRO bonding or that separate.When this fastening astragal is bundled on sandbag, column or human body, justify hair side 105 by VELCRO bonding with VELCRO thorn hair side 106; Fastening astragal need to be separated to sandbag, column or human body time, only VELCRO circle hair side 105 and VELCRO thorn hair side 106 need be taken apart, convenient and practical.
When target body 102 is fixed on this fastening astragal, can be fixed on any position on this fastening astragal, for attractive in appearance, can be symmetricly set in the central authorities of fastening astragal, fastening astragal is divided into left fastening astragal 103 and right fastening astragal 104 two parts.Certainly, in other embodiments, also can adopt independently two fastening astragals, link together by target body 102.
Incorporated by reference to Fig. 2, target body 102 comprises all for playing soft upper confining bed 401 and the soft bottom impermeable layer 404 of buffering and protective effect and being laid in the piezoelectric membrane 402 and flexible flexible hard substrate 403 between upper confining bed 401 and bottom impermeable layer 404.Upper confining bed 401 and substrate 403 depend on respectively two opposite flanks of piezoelectric membrane 402.
Upper confining bed 401 all can be sponge with bottom impermeable layer 404, mainly plays a part buffering and protection piezoelectric membrane 402.Piezoelectric membrane 402 can be piezo-electric electret thin film, and the two poles of the earth of piezoelectric membrane 402 connect into circuit, for man machine operation interface 101 analyzing and processing signals.Substrate 403 depends on the back side of piezoelectric membrane 402, plays a part protection piezoelectric membrane 402.Four layers of target body 102 are well stitched together, and the transmission of exerting all one's strength is evenly undamped.Upper confining bed 401 adopts spongy layer, can also allow user have good body sense, also allows outward appearance of the present invention comparatively attractive in appearance.Substrate 403 has limited the bending of piezoelectric membrane 402, can not allow piezoelectric membrane 402 too be recessed to form damage.Bottom impermeable layer 404 is sponge, also because there being certain elasticity, can form grip, is convenient to be fixed on pillar and human body.
Signal of the present invention is to be provided by piezoelectric membrane 402, piezoelectric membrane 402 is fixed between confining bed 401, bottom impermeable layer 404 and substrate 403, so as long as piezoelectric membrane 402 does not damage, measurement effect of the present invention just can not be affected, the shake that boxing brings also can not exert an influence to measuring
Piezoelectric membrane 402 comprises three piezoelectric charge coefficients, these three piezoelectric charge coefficients represent respectively the vibration sensitivity in X, Y, tri-orthogonal directions of Z, wherein, X Y plane parallel is in target body 102, high 1 ~ 2 order of magnitude of the numerical value of two piezoelectric charge coefficients in numeric ratio X, the Y-direction of the piezoelectric charge coefficients in Z direction.The transmission of boxing power is vertical transmission, therefore need to be designed to: Z direction (being vertical direction, perpendicular to the direction of target body 102) vibration sensitivity is high, and X, Y-direction are (horizontal, being parallel to the direction of target body 102) vibration sensitivity is very low, thus the degree of accuracy that improves dynamometry.
