Description
Technical field
the utility model relates to a kind of energy collecting device, particularly a kind of device vibrational energy being converted into electric energy in wide frequency range.
Background technology
due to the progress of technology, the application development of wireless device in the last few years, its powerup issue also gets more and more people's extensive concerning.Piezoelectric energy collecting device, as a kind of novel miniature power generating device, has that structure is simple, caloric value is little, without electromagnetic interference, the miniaturization be easy on processing and fabricating and implementation structure, the advantage such as integrated, is applicable to all kinds of sensing and monitoring system.Piezoelectric energy collecting device major part is in the market structure based on cantilever beam, and utilizes its modal vibration to obtain electric energy.This collection of energy mode has the features such as efficiency is higher, frequency range is narrower, cannot collect the vibrational energy under higher frequency.Therefore, be necessary to develop a kind of frequency range relatively wider, the energy collecting device that power supplying efficiency is higher.
Utility model content
the purpose of this utility model is, provides a kind of energy collecting device.The utility model can collect vibrational energy in wider frequency range, improves collection of energy transformation efficiency.
the technical solution of the utility model: a kind of energy collecting device, it is characterized in that: comprise and to be fixed on vibrational structure body and symmetrically arranged two holders through screw, the beam-shaped structure body that many thickness is different is provided with between two holders, both sides in the middle part of every root beam-shaped structure body are provided with stretches out cantilever beam, stretch out cantilever beam upper surface and be provided with piezoelectric patches A, described every root beam-shaped structure body two ends upper surface is provided with piezoelectric patches B.
in aforesaid energy collecting device, the different beam-shaped structure body of described many thickness comprises many beam-shaped structure bodies that thickness increases successively.
in aforesaid energy collecting device, described piezoelectric patches A is arranged near beam-shaped structure body.
in aforesaid energy collecting device, described beam-shaped structure body is the beam-shaped structure body that stainless steel or aluminium are formed.
compared with prior art, the utility model is fixed on vibrational structure body by the beam-shaped structure body two ends of many different-thickness, and produce strain maximum position at different resonant frequencies underbeam shape structure, middle two of beam-shaped structure body is driven to stretch out cantilever beam resonance, thus produce its strain maximum position, namely two are relatively stretched out on cantilever beam and arrange piezoelectric patches, girder two ends arrange piezoelectric patches, the interaction of being stretched out cantilever beam by beam-shaped structure body and two strengthens vibration, the vibrational energy of surrounding environment can be absorbed in very wide frequency range, thus increase substantially collection of energy transformation efficiency.The utility model is applied to the power supply device of network and Wireless Telecom Equipment.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
being labeled as in accompanying drawing: 1-vibrational structure body, 2-screw, 3-holder, 4-piezoelectric patches A, 5-first beam-shaped structure body, 6-second beam-shaped structure body, 7-the 3rd beam-shaped structure body, 8-piezoelectric patches B, 9-stretches out cantilever beam.
Embodiment
below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
embodiment.A kind of energy collecting device, form as shown in Figure 1, comprise and to be fixed on vibrational structure body 1 and symmetrically arranged two holders 3 through screw 2, the beam-shaped structure body that many thickness is different is provided with between two holders 3, both sides in the middle part of every root beam-shaped structure body are provided with stretches out cantilever beam 9, stretch out cantilever beam 9 upper surface and be provided with piezoelectric patches A4, described every root beam-shaped structure body two ends upper surface is provided with piezoelectric patches B8.
reasonable, the different beam-shaped structure body of described many thickness comprises many beam-shaped structure bodies that thickness increases successively.Be more preferably, the different beam-shaped structure body of described many thickness comprises many beam-shaped structure bodies that thickness increases exponentially successively, and many articles of beam-shaped structure bodies can be the first beam-shaped structure body 5, second beam-shaped structure body 6 and the 3rd beam-shaped structure body 7.
reasonable, described piezoelectric patches A4 is arranged near beam-shaped structure body.
reasonable, described beam-shaped structure body is the beam-shaped structure body that stainless steel or aluminium are formed.
reasonable, described holder 3 is L shape holders, the opposing setting of two L shape holders.
many beam-shaped structure bodies of the present utility model are fixed on vibrational structure body, vibrate together along with vibrational structure body to make beam-shaped structure body.Because beam-shaped structure body 5,6,7 thickness increases progressively, therefore its vibration frequency increases progressively.When vibration frequency is less, the first beam-shaped structure body 5 Oscillation Amplitude is comparatively large, and the effect due to magnetic force causes the second beam-shaped structure body 6 and the 3rd beam-shaped structure body 7 amplitude strengthens, and frequency also promotes to some extent.When vibration frequency increases, the second beam-shaped structure body 6 Oscillation Amplitude is comparatively large, and the effect due to magnetic force causes the first beam-shaped structure body 5 and the 3rd beam-shaped structure body 7 amplitude strengthens, and frequency also promotes to some extent.When vibration frequency is larger, the 3rd beam-shaped structure body 7 Oscillation Amplitude is comparatively large, and the effect due to magnetic force causes the first beam-shaped structure body 5 and the second beam-shaped structure body 6 amplitude strengthens, and frequency also promotes to some extent.In addition, the beam-shaped structure body of different-thickness due to the quality of self different, be fixed on beam-shaped structure body, the resonance frequency of vibrational structure body self can be regulated.Therefore the utility model is fixed on vibrational structure body by the beam-shaped structure body two ends of three kinds of different-thickness, and piezoelectric patches is set at middle two cantilever beam upper surfaces relatively stretched out, girder two ends arrange piezoelectric patches, the interaction of being stretched out cantilever beam by girder and two strengthens vibration, the vibrational energy of surrounding environment can be absorbed in very wide frequency range, thus increase substantially collection of energy transformation efficiency.
