Abstract
The invention discloses a piezoelectric vibration battery. The piezoelectric vibration battery comprises a casing (3), an upper cover (2), a lower cover (4), a mass block (1), a plurality of cantilever beams (5) and piezoelectric sheets (6), wherein the mass block (1) is placed in the casing (3) and is supported by one ends of the cantilever beams (5), the other end of each cantilever beam (5) is fixed on the casing (3), and one piezoelectric sheet (6) is adhered to one end, close to the casing (3), of each cantilever beam (5). According to the piezoelectric vibration battery disclosed by the invention, piezoelectricity and power generation capacity is greatly improved, and the generated electric energy can satisfy the requirements of non-source type microelectronic devices.
Description
Technical field
The invention belongs to cell art, particularly a kind of piezoelectric vibration battery.
Background technology
Piezoelectric type self energizing device is the important component part in passive type microelectronic device research field.As an alternative traditional energy-provision way energy source for microelectronic device energy is provided, self-energizing key chooses the energy and the transform mode of environment residing for applicable transducer and electronic system, make it have enough power outputs and be supplied to electronic system.In the research of microelectronic device passive, piezoelectric type self energizing device obtains the emphasis that the mode of vibrational energy and efficiency are research at present from external environment.Along with the development of passive type microelectronic device research, also more and more higher to the requirement of the generating capacity of piezoelectric type self energizing device.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of piezoelectric vibration battery, and this piezoelectric vibration battery has stronger generating capacity than piezocell in the past.
A kind of piezoelectric vibration battery of the present invention, comprise shell, upper and lower cover, mass, cantilever beam and piezoelectric patches.Described mass is placed in enclosure, and supported by some cantilever beam one end, every root cantilever beam other end is fixed on shell, and cantilever beam posts a piezoelectric patches near shell one end.
As the further improvement of technique scheme, described cantilever beam is uniformly distributed around mass.
As the further improvement of technique scheme, described cantilever beam is total some layers from top to bottom.
Another kind as technique scheme improves, and described shell is cylindrical, and the central shaft of mass overlaps with the central shaft of shell.
Another kind as technique scheme improves, and described cantilever beam is trapezoidal, trapezoidal upper base is that end contacted with mass, goes to the bottom as that end with housing contacts.
The ability of piezoelectric vibration battery piezo-electric generating of the present invention improves greatly, and the electric energy of generation can meet the demand of passive type microelectronic device.
