Technical field
The present invention relates to a kind of ultrasound wave wireless energy transfer intensifier, belong to the technical field of wireless energy transfer.
Background technology
In the ultrasound wave wireless energy transfer;-curved vibration mode coupling transducer vertical when using is during as the emission oscillator of system; The emission oscillator can be because the flexural vibrations of radiant panel; Produce vibration phase on the surface of the surface of emission and distinguish on the contrary, thereby the radiated sound field directivity that causes launching oscillator is poor, make the little energy that pick-up dipole receives.Even the transducer that adopts good directionality in addition is as the emission oscillator, the sound wave that the emission oscillator produces also can outwards be the diffusion of truncated cone-shaped owing to the physical characteristics of sonic transmissions by acoustic axis.Because the shortcoming of emission oscillator directivity difference can cause the loss of ultrasound wave wireless energy transfer energy, has reduced the efficient of ultrasound wave wireless energy.
Summary of the invention
Technical matters to be solved by this invention is to the deficiency of above-mentioned background technology, and a kind of ultrasound wave wireless energy transfer intensifier is provided.
The present invention adopts following technical scheme for realizing the foregoing invention purpose:
A kind of ultrasound wave wireless energy transfer intensifier comprises: booster, oscillator matching layer, piezoelectric ceramics, oscillator back shroud, converter plant; Wherein: booster is installed in the face of accepting of oscillator matching layer; Piezoelectric ceramics bonds with oscillator matching layer, oscillator back shroud respectively through cementing agent; The output terminal of piezoelectric ceramics is connected with the input end of converter plant through the oscillator back shroud, and the output terminal of converter plant is connected with load;

Embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to invention:
Ultrasound wave infinite energy transmission intensifier as shown in Figure 1 comprises booster 2, oscillator matching layer 3, piezoelectric ceramics 4, oscillator back shroud 5, converter plant 6.Booster 1 is installed in the face of accepting of oscillator matching layer 3, and piezoelectric ceramics 4 places between oscillator matching layer 3 and the oscillator back shroud 5, and the input end of converter plant 6 is connected with the output terminal of piezoelectric ceramics 4, and the output terminal of converter plant 6 is connected with load 7.
Because sound wave 1 can produce repeatedly reflection and transmission after getting into booster 2 on the inwall of booster 2, will be enhanced device 2 itself at the energy of booster 2 transmissions and absorb, so the present invention selects the material booster 2 of the acoustic resistance Chinese People's Anti-Japanese Military and Political College for use.Being shaped as of booster is horn-like; Be similar to the shape of dynamic loudspeaker; The small-caliber end of tubaeform tubulose body is the same with the bore that the oscillator matching layer is accepted face, and the length of tubaeform tubulose body and ultrasound waves appearance are same, and booster can make acoustic wave energy assemble like this; And the vibration displacement that the density of material of oscillator back shroud makes the oscillator matching layer greater than the density of material of oscillator matching layer is much larger than the oscillator back shroud, thereby guaranteed effective emission of ultrasonic energy.
Booster is assembled the sound wave that receives; The acoustic impedance of oscillator matching layer coupling air and the acoustic impedance of piezoelectric ceramics make sound wave in piezoelectric ceramics, propagate; Piezoelectric ceramics is converted into alternating current with the mechanical energy that acoustic vibration produces; Alternating current gets into converter plant after through the oscillator back shroud, and it is electric that converter plant converts alternating current into direct current.
It is thus clear that, after the maximized gathering of the ultrasound wave tubaeform tubulose body booster of process, be able in piezoelectric ceramics, propagate through the oscillator matching layer, effectively improve the problem of emission oscillator directivity difference.The vibration displacement that the density of material of oscillator back shroud makes the oscillator matching layer greater than the density of material of oscillator matching layer is much larger than the oscillator back shroud, thereby guaranteed effective emission of ultrasonic energy, effectively improves the work efficiency of ultrasound wave wireless energy transfer system.
