Abstract
The present invention relates to a kind of drawer formula vibration prisoner's energy battery, including：Battery cap, battery case, middle piezoelectric cantilever and two small piezoelectric cantilevers, wherein：The battery cap and battery case constitute cell sealing chamber；The middle piezoelectric cantilever and two small piezoelectric cantilevers constitute piezoelectric generating device.When the device, which is arranged in, replaces conventional batteries in vibration or the micro-electromechanical device rolled, three piezoelectric cantilevers of inside battery can radially be vibrated in drawer groove, and the mass in the middle of piezoelectric cantilever also can mutually be hit, and piezoelectric cantilever generating efficiency is significantly improved.Drawer formula vibration prisoner's energy battery, generating efficiency is good when by radial vibration or rolling, when being arranged in micro-electromechanical device, has the advantages that simple in construction, non-maintaining, long lifespan, energy-conserving and environment-protective, is easily integrated.
Description
Technical field
The invention belongs to field of piezoelectric generation, and in particular to a kind of drawer formula vibration prisoner can battery.
Background technology
With the development of science and technology, confession power technology power in MEMS, wireless sensor network node confession
Electricity, military affairs electronic product, biologic medical electronic product, human lives' electronic product etc. occupy increasingly consequence.Pass
System dry cell or lithium battery volume is larger is not easy to integrated with micro-electromechanical device, and short life is, it is necessary to safeguard and change, also simultaneously
In the presence of pollution., output voltage relatively low the problems such as larger with coil dimension that electromagnetic type piezoelectric self electricity battery has a magnet.And piezoelectricity
TRT can be converted to ambient vibration mechanical energy, and piezoelectric power generating device is easily integrated, without electromagnetic interference, using the longevity
Life length, therefore, piezoelectric self power technology is shown one's talent, wherein the electric structure of the piezoelectric self invented using ambient vibration is increasingly
It is many.However, it is existing vibration piezoelectric energy-capturing battery be practically applicable to mostly battery occur single type vibration, when battery be in roll or
During radial vibration, piezoelectric energy-capturing efficiency is substantially reduced.
The content of the invention
In order to solve vibration prisoner's energy battery structure complexity general at present, capture energy in battery radial vibration or rolling vibration
The problem of efficiency is not strong, it is proposed that a kind of drawer formula vibrates prisoner's energy battery, and drawer formula vibration prisoner's energy battery is outside battery cap, battery
Shell, middle piezoelectric cantilever and both sides piezoelectric cantilever are constituted, the sealed cylinder of battery cap and battery case composition
Three piezoelectric cantilevers are installed in cavity, inside cavity drawer groove, when cell body rolls or is radially vibrated, piezoelectric cantilever
It is of reciprocating vibration in drawer groove, while can mutually be collided between the mass of three piezoelectric cantilever center arrangements, strengthen piezoelectricity and hang
Arm beam deformation quantity and vibration number, lift piezoelectric energy-capturing efficiency.The energy that piezoelectric patches is sent by wire be connected to battery cap and
The electrode arranged on battery case cylinder bottom, is re-introduced to external current-regulating circuit and storage capacitor, is used for external electronic component.Should
Drawer formula vibration prisoner's energy battery, was mainly used in vibrating or rolls more micro-electromechanical device, with simple in construction, the non-maintaining, life-span
Length, energy-conserving and environment-protective, the advantages of be easily integrated.
To achieve these goals, the present invention uses following technical scheme：
A kind of drawer formula vibration prisoner energy battery of the present invention, including：Battery cap (1), battery case (2), it is characterised in that also
Including middle piezoelectric cantilever (3) and two small piezoelectric cantilever (4), the battery cap (1) is disc component, its upper table
Face center is disposed with round boss electrode；The battery case (2) is the circle tube member bottom of with, and cylinder interior arranges three
Along the drawer groove in cylinder axis direction, cylinder base fabric is equipped with electrode；The battery cap (1) connects and composes cylinder with battery case (2)
Shape cell sealing cavity；The middle piezoelectric cantilever (3) is as two small piezoelectric cantilever (4) structure, and size is different, in
Between piezoelectric cantilever (3) be made up of elastic base plate (31), piezoelectric patches (32) and mass (33), elastic base plate (31) is by a square
The frame composition of shape cantilever beam and cantilever mounted beam, piezoelectric patches (32) is symmetrically pasted onto rectangular cantilever beam upper and lower surface, mass
(33) it is symmetrical to be pasted onto piezoelectric patches center；The middle piezoelectric cantilever (3) and two small piezoelectric cantilever (4) are placed on battery
In the internal drawer groove of shell (2), and gap is left with drawer groove.
During work, this drawer formula is vibrated into prisoner's energy battery arrangement in micro-electromechanical device that is vibrated more or rolling, battery
Internal piezoelectric cantilever produces collision up and down in drawer groove causes piezoelectric cantilever to deform, while piezoelectric cantilever hits exactly cloth
The mass put also can be collided mutually, strengthen piezoelectric cantilever deformation quantity and vibration number, the electric energy that piezoelectric patches is sent is by leading
Line is connected to the electrode arranged on battery cap and battery case cylinder bottom, external current-regulating circuit and storage capacitor is re-introduced to, for outside
Electronic component is used.
