Description
Technical field
The utility model belongs to new forms of energy and technical field of power generation, is specifically related to a kind of hand-rail type piezoelectric generating device, is used for the remote controller power supply.
Background technology
Remote controller is to use the most general micropower electronic product in the actual life, is widely used in the control of all kinds of household appliances, like television set, video tape recorder, VCD, air-conditioning etc.Present remote controller all is the chemical cell power supply, existing 1,400,000,000 populations of China, and only the used battery of TV remote controller just reached for 9.2 hundred million joint/years, is worth 7,000,000,000 yuan; In addition, because of battery contains heavy metal, deal with improperly and can cause serious environmental to pollute, therefore adopting the microminiature TRT to substitute battery is that the remote controller power supply is imperative.
At present, all proposed polytype TRT both at home and abroad and be used for remote controller power supply, wherein using more two types is micro electromagnetic TRT and piezoelectric generating device.Wherein, Electromagnetic power generation apparatus energy conversion efficiency higher relatively, but owing to need to adopt magnet and coil to do relative motion to generate electricity, so complex structure, volume are big; And electromagnetic field possibly exert an influence to the information emission of remote controller, is not suitable for the application that volume is little, reliability is high; And piezoelectric generating device utilizes the flexural deformation of sheet type piezoelectric vibrator to convert mechanical energy to electric energy, has simple in structure, characteristics such as volume is little, cost is low, no electromagnetic interference, is more suitable for the application of Digiplex.In existing all kinds of TRTs, it is the most general that the cantilever beam type piezoelectric vibrator is used, but an end is fixed, maximum, the free end stress of the suffered stress of stiff end is zero during end cantilever beam piezoelectric vibrators distortion freely, so generating capacity is not fully exerted; In addition, when suffered external force or be out of shape and cause when excessive piezoelectric ceramic broken, can't continue to use.
Summary of the invention
The utility model provides a kind of remote controller to use the hand-rail type piezoelectric generating device, to solve drawbacks such as existing beam type piezoelectric generating device generating capacity and reliability are low.
The technical scheme that the utility model adopts is: housing is connected through screw with panel, between this housing and the panel circuit board is installed, and on this circuit board button is installed; Be provided with a pair of arc surface of using in the said housing, the end in the said housing also is provided with narrow groove; Be bonded with piezoelectric vibrator in the said narrow groove, this piezoelectric vibrator is by metal substrate, two bonding forming of piezoelectric chip, and said two piezoelectric chips connect through lead; Said metal substrate is connected with circuit board through the lead group with piezoelectric chip; The free end of this piezoelectric vibrator is bonded with mass.
In the utility model, TRT is made up of circular arc confined planes, piezoelectric vibrator on housing, the housing and the mass that is installed on the piezoelectric vibrator end.Under the nature, piezoelectric vibrator does not receive the external force effect, does not produce deformation in the raw; When hand housing rocked, the inertia force of mass forced piezoelectric vibrator to produce flexural deformation, and when the inertia force that is produced was enough big, the surface of piezoelectric vibrator abutted on the spacing disc fully, and converts mechanical energy to electric energy; The electric energy that is generated goes out to deliver to the remote controller control circuit on the circuit board through the lead group.
The characteristics and the advantage of the utility model are, utilize the deformed shape of arc surface restriction piezoelectric vibrator, and the radius of the each point on the piezoelectric vibrator of distortion back and bending stress and energy output equate that therefore overall generating capacity is higher; In addition, during piezoelectric vibrator flexural deformation, its minimum bending radius is the radius of spacing circular arc, and it is excessive and damage that reason is not shaken amplitude, has higher reliability.
