[発電装置]
図1及び図2に示されるように、発電装置20は、ハウジング22と、把持部材24と、圧電部材26と、接続部材28とを備えている。
[Power generation equipment]
As shown in FIGS. 1 and 2, the power generation device 20 includes a housing 22, a grip member 24, a piezoelectric member 26, and a connection member 28.
(装着部材)
装着部材の一例としてのハウジング22は、携帯端末100の背面100B(操作面を正面100Aとした場合の背面)に装着される部材であり、箱状とされている。このハウジング22の内部には、後述する整流回路34や配線類が内蔵されている。また、ハウジング22は、樹脂材料で形成されており、携帯端末100の背面100Bに接着テープ等の接着部材で接着されている。なお、本実施形態では、ハウジング22を携帯端末100の背面100Bに接着しているが、本発明はこの構成に限定されない。例えば、携帯端末100にブラケット等を取り付けて該ブラケットにハウジング22を装着させる構成であってもよいし、携帯端末100用の専用ケースの背面にハウジング22を装着させる構成としてもよい。
(Mounting member)
The housing 22 as an example of a mounting member is a member that is mounted on the back surface 100B of the mobile terminal 100 (the back surface when the operation surface is the front surface 100A), and has a box shape. Inside the housing 22, a rectifier circuit 34 and wirings to be described later are incorporated. The housing 22 is formed of a resin material, and is adhered to the back surface 100B of the mobile terminal 100 with an adhesive member such as an adhesive tape. In the present embodiment, the housing 22 is bonded to the back surface 100B of the mobile terminal 100, but the present invention is not limited to this configuration. For example, a configuration in which a bracket or the like is attached to the mobile terminal 100 and the housing 22 is mounted on the bracket may be used, or a configuration in which the housing 22 is mounted on the back surface of a dedicated case for the mobile terminal 100 may be used.
(動作部材)
動作部材の一例としての把持部材24は、ハウジング22に設けられて手動操作により動作する部材である。具体的には、把持部材24は、図2(B)に示されるように、手動操作としての把持操作によって弾性変形する部材である。この把持部材24を形成する材料としては、例えば、クッション材を用いることができる。
(Operational member)
The grip member 24 as an example of the operation member is a member that is provided in the housing 22 and operates by manual operation. Specifically, as shown in FIG. 2B, the grip member 24 is a member that is elastically deformed by a grip operation as a manual operation. As a material for forming the grip member 24, for example, a cushion material can be used.
また、把持部材24には、携帯端末100の側方へ張り出し、指が掛かる波形状のグリップ部30が形成されている。このグリップ部30に指を掛けることで、把持部材24の把持操作がしやすくなっている。なお、本実施形態のグリップ部30には、指が掛かる凹状部30Aが複数(3つ)形成されている。   In addition, the grip member 24 is formed with a wave-shaped grip portion 30 that protrudes to the side of the mobile terminal 100 and is hooked by a finger. By holding the finger on the grip portion 30, the gripping operation of the gripping member 24 is facilitated. In addition, the grip part 30 of this embodiment is formed with a plurality (three) of concave parts 30A on which fingers are to be applied.
さらに、把持部材24の圧電部材26に対向した位置には、把持操作によって弾性変形する把持部材によって圧電部材26を加圧する加圧部材32が設けられている。なお、本実施形態では、グリップ部30の凹状部30Aに対応した位置に圧電部材26が配置されている。   Further, a pressing member 32 that pressurizes the piezoelectric member 26 by a gripping member that is elastically deformed by a gripping operation is provided at a position facing the piezoelectric member 26 of the gripping member 24. In the present embodiment, the piezoelectric member 26 is disposed at a position corresponding to the concave portion 30 </ b> A of the grip portion 30.
(圧電部材)
圧電部材26は、把持部材24の動作によって発電する部材(所謂、圧電素子)である。具体的には、把持部材24の把持操作によって加圧部材32が圧電部材26を加圧することで、圧電部材26が圧電効果によって発電するようになっている。なお、本実施形態では、圧電性セラミックで圧電部材26を構成している。
(Piezoelectric member)
The piezoelectric member 26 is a member (so-called piezoelectric element) that generates electricity by the operation of the gripping member 24. Specifically, the pressing member 32 pressurizes the piezoelectric member 26 by the gripping operation of the gripping member 24, so that the piezoelectric member 26 generates power by the piezoelectric effect. In the present embodiment, the piezoelectric member 26 is made of piezoelectric ceramic.
また、圧電部材26は、ハウジング22の側面22Aに形成された収容凹部23に収容されている。なお、本実施形態では、ハウジング22の側面22Aに複数(3つ)の収容凹部23が形成されており、それらの収容凹部23に圧電部材26がそれぞれ収容されている。これらの圧電部材26は、収容凹部23に収容された状態では、複数の加圧部材32に対してそれぞれ対向して配置されている。   The piezoelectric member 26 is accommodated in an accommodation recess 23 formed on the side surface 22 </ b> A of the housing 22. In the present embodiment, a plurality (three) of accommodating recesses 23 are formed on the side surface 22A of the housing 22, and the piezoelectric members 26 are accommodated in the accommodating recesses 23, respectively. These piezoelectric members 26 are disposed so as to face the plurality of pressure members 32 in the state of being accommodated in the accommodating recess 23.
(接続部材)
接続部材28は、圧電部材26と携帯端末100の充電部を電気的に接続する部材である。この接続部材28は、圧電部材26が発電した電流を整流する整流回路34と、携帯端末100の図示しない充電端子に挿入接続される接続端子36と、圧電部材26から接続端子36までの電気配線38とを含んで構成されている。
(Connecting member)
The connection member 28 is a member that electrically connects the piezoelectric member 26 and the charging unit of the mobile terminal 100. The connection member 28 includes a rectification circuit 34 that rectifies the current generated by the piezoelectric member 26, a connection terminal 36 that is inserted and connected to a charging terminal (not shown) of the portable terminal 100, and electrical wiring from the piezoelectric member 26 to the connection terminal 36. 38.
次に、本実施形態の発電装置20の作用効果について説明する。   Next, the effect of the power generator 20 of this embodiment is demonstrated.
発電装置20は、携帯端末100を持ち、把持部材24を把持した操作者が把持操作、すなわち、グリップ部30の凹状部30Aに指を掛けて把持を繰り返すことで、把持部材24内に配置された加圧部材32が圧電部材26を繰り返し加圧する(図2(B)参照)。圧電部材26は、加圧されることで、圧電効果によって発電する。このとき発電される電流は、パルス状であるが、整流回路34で平滑化され、電気配線38を通って、接続端子36から携帯端末100の充電部へ供給され、充電部が充電される。   The power generation device 20 is arranged in the gripping member 24 by holding the mobile terminal 100 and an operator who grips the gripping member 24 repeatedly grips the gripping operation, that is, puts a finger on the concave portion 30A of the grip portion 30 and repeats gripping. The pressed member 32 repeatedly pressurizes the piezoelectric member 26 (see FIG. 2B). The piezoelectric member 26 generates electric power by the piezoelectric effect when pressed. The current generated at this time is in a pulse form, but is smoothed by the rectifier circuit 34 and supplied to the charging unit of the portable terminal 100 from the connection terminal 36 through the electric wiring 38, and the charging unit is charged.
ここで、発電装置20では、携帯端末100を持ちながら、把持部材24を把持する把持操作で携帯端末100の充電部に充電をすることができる。すなわち、発電装置20は、充電部を備えた携帯端末100に対して簡単な手動操作で充電をすることができる、という格別な効果を奏する。なお、携帯端末100の操作時などに把持部材24を把持操作することで携帯端末100の充電部に充電できるため、携帯端末100の充電回数を減らすことができる。さらに、携帯端末100用の専用充電器を持ち運ぶ必要がなくなる。   Here, in the power generation device 20, the charging unit of the mobile terminal 100 can be charged by a gripping operation of gripping the gripping member 24 while holding the mobile terminal 100. That is, the power generation device 20 has an exceptional effect that the mobile terminal 100 including the charging unit can be charged by a simple manual operation. In addition, since the charging part of the mobile terminal 100 can be charged by gripping the gripping member 24 when operating the mobile terminal 100, the number of times the mobile terminal 100 is charged can be reduced. Furthermore, it is not necessary to carry a dedicated charger for the portable terminal 100.
また、発電装置20では、把持部材24内に設けられた加圧部材32を介して圧電部材26を加圧するため、圧電部材26に対して効率よく加圧力を作用させることができる。これにより、圧電部材26の発電効率が向上する。さらに、圧電部材26を複数設けているため、発電量を向上させることができる。   Further, in the power generation apparatus 20, the piezoelectric member 26 is pressurized via the pressurizing member 32 provided in the gripping member 24, so that the pressurizing force can be efficiently applied to the piezoelectric member 26. Thereby, the power generation efficiency of the piezoelectric member 26 is improved. Furthermore, since a plurality of piezoelectric members 26 are provided, the power generation amount can be improved.
また、発電装置20では、把持部材24にグリップ部30を形成しているため、把持部材24を把持しやすい。そして、グリップ部30に指を掛けることで、把持部材24の把持操作がしやすくなっている。   In the power generation device 20, since the grip portion 30 is formed on the grip member 24, the grip member 24 can be easily gripped. Then, by gripping the grip portion 30 with a finger, the gripping operation of the gripping member 24 is facilitated.
前述の第1実施形態では、動作部材の一例として把持部材24を用いたが、本発明はこの構成に限定されない。例えば、図3に示される発電装置40のように、動作部材の一例として把持部材42を用いてもよい。発電装置40では、ハウジング22の側面22Aに凹状のバネ収容部44を設け、このバネ収容部44にコイルスプリング46を収容している。なお、このハウジング22は、圧電部材26を備え、整流回路34を収容している。また、把持部材42は、グリップ部30と加圧部材32を備え、さらに、コイルスプリング46を収容したバネ収容部44に収容される棒状部47を備えている。この把持部材42は、把持操作によってハウジング22側へ押圧されると、スライド移動し、加圧部材32が圧電部材26を加圧するようになっている(図3(B)参照)。また、ハウジング22の高さ方向Xの対向面22Bには、幅方向Yに沿って延びる溝部22Cが形成されており、この溝部22Cに把持部材42に設けられたストッパ部48が引っ掛かっている。このストッパ部48は、溝部22Cの延在方向(ここでは幅方向Yと同じ方向)の両端部にそれぞれ当接することで、把持部材42の移動を制限可能とされている。発電装置40では、把持部材42を把持し、この把持部材42をハウジング22に向けて押圧することで、把持部材42がスライド移動して加圧部材32によって圧電部材26が加圧される。ここで、ハウジング22側へ移動させた把持部材42は、コイルスプリング46の反発力によって元の位置へと移動するため、テンポよく把持部材42を把持操作することができる。   In the first embodiment described above, the grip member 24 is used as an example of the operating member, but the present invention is not limited to this configuration. For example, like the power generation device 40 shown in FIG. 3, the grip member 42 may be used as an example of the operation member. In the power generation device 40, a concave spring accommodating portion 44 is provided on the side surface 22 </ b> A of the housing 22, and a coil spring 46 is accommodated in the spring accommodating portion 44. The housing 22 includes a piezoelectric member 26 and houses a rectifier circuit 34. The gripping member 42 includes a grip portion 30 and a pressure member 32, and further includes a rod-shaped portion 47 that is accommodated in a spring accommodating portion 44 that accommodates a coil spring 46. When the gripping member 42 is pressed toward the housing 22 by a gripping operation, the gripping member 42 slides and the pressure member 32 pressurizes the piezoelectric member 26 (see FIG. 3B). Further, a groove portion 22C extending along the width direction Y is formed on the opposing surface 22B in the height direction X of the housing 22, and a stopper portion 48 provided on the gripping member 42 is hooked on the groove portion 22C. The stopper portion 48 is capable of restricting the movement of the gripping member 42 by abutting against both end portions in the extending direction (here, the same direction as the width direction Y) of the groove portion 22C. In the power generation device 40, the gripping member 42 is gripped and the gripping member 42 is pressed toward the housing 22, so that the gripping member 42 slides and the pressure member 32 pressurizes the piezoelectric member 26. Here, since the gripping member 42 moved to the housing 22 side is moved to the original position by the repulsive force of the coil spring 46, the gripping member 42 can be gripped with good tempo.
また、前述の第1実施形態では、把持部材24のグリップ部30の形状が操作者の指(例えば、小指、薬指、中指)を掛けることができる形状とされているが、本発明はこの構成に限定されない。例えば、把持部材24のグリップ部30の形状を親指の付け根付近の平部で加圧できる形状としてもよい。グリップ部30の形状をこのような形状とすることで、親指の平部を用いる把持操作によっても発電することができる。またさらに、発電装置のハウジングの幅方向Yの一方の側面に把持部材24を設け、幅方向Yの他方の側面に上記親指の平部に対応した形状の把持部材を設ける構成としてもよい。このような構成とすることで、携帯端末100を持った手の指(3本の指)と親指の平部とで、把持部材24と上記親指の平部に対応した形状の把持部材を一緒に把持できるため、発電効率及び発電量をさらに向上させることができる。   Further, in the first embodiment described above, the shape of the grip portion 30 of the gripping member 24 is a shape that allows the operator's finger (for example, little finger, ring finger, middle finger) to be hung, but the present invention has this configuration. It is not limited to. For example, the shape of the grip portion 30 of the grip member 24 may be a shape that can be pressed by a flat portion near the base of the thumb. By setting the shape of the grip portion 30 to such a shape, it is possible to generate power even by a gripping operation using the flat portion of the thumb. Furthermore, it is good also as a structure which provides the holding member 24 in one side surface of the width direction Y of the housing of an electric power generating apparatus, and provides the holding member of the shape corresponding to the said flat part of the thumb on the other side surface of the width direction Y. With this configuration, the gripping member 24 and the gripping member having a shape corresponding to the flatness of the thumb are combined with the fingers (three fingers) of the hand holding the mobile terminal 100 and the flatness of the thumb. Therefore, the power generation efficiency and power generation amount can be further improved.

次に、本実施形態に係る発電装置50について図4〜図6に基づいて説明する。なお、本実施形態では、発電装置50を携帯端末100に装着している。
(Second Embodiment)
Next, the power generation device 50 according to the present embodiment will be described with reference to FIGS. In the present embodiment, the power generation device 50 is attached to the mobile terminal 100.
[発電装置]
図4及び図5に示されるように、発電装置50は、ハウジング52と、回転カム54と、圧電部材26と、接続部材28とを備えている。
[Power generation equipment]
As shown in FIGS. 4 and 5, the power generation device 50 includes a housing 52, a rotating cam 54, a piezoelectric member 26, and a connection member 28.
(装着部材)
装着部材の一例としてのハウジング52は、携帯端末100の背面100Bに装着される部材であり、箱状とされている。このハウジング52の内部には、整流回路34や配線類が内蔵されている。また、ハウジング52は、樹脂材料で形成されており、携帯端末100の背面100Bに接着テープ等の接着部材で接着されている。なお、ハウジング52の携帯端末100に対する装着方法は、第1実施形態のハウジング22と同様のものを用いることができる。
(Mounting member)
The housing 52 as an example of a mounting member is a member that is mounted on the back surface 100B of the mobile terminal 100 and has a box shape. Inside the housing 52, a rectifier circuit 34 and wirings are incorporated. The housing 52 is formed of a resin material, and is adhered to the back surface 100B of the mobile terminal 100 with an adhesive member such as an adhesive tape. In addition, the mounting method with respect to the portable terminal 100 of the housing 52 can use the thing similar to the housing 22 of 1st Embodiment.
(動作部材)
動作部材の一例としての回転カム54は、ハウジング52に設けられて手動操作により動作する部材である。具体的には、回転カム54は、図4及び図5に示されるように、手動操作としての回転操作によって回転する部材である。この回転カム54には、外周に張り出すカム部54Aが周方向に間隔をあけて複数形成されている。また、回転カム54は、ハウジング52に対して厚み方向Zを回転軸方向として回転可能に取り付けられている。
(Operational member)
The rotating cam 54 as an example of the operating member is a member that is provided in the housing 52 and operates by manual operation. Specifically, as shown in FIGS. 4 and 5, the rotating cam 54 is a member that is rotated by a rotating operation as a manual operation. The rotating cam 54 is formed with a plurality of cam portions 54A projecting on the outer periphery at intervals in the circumferential direction. The rotating cam 54 is attached to the housing 52 so as to be rotatable with the thickness direction Z as the rotation axis direction.
また、ハウジング52内には、支持部56が設けられており、この支持部56に板バネ58と支持板60とが高さ方向Xに対向して配置されている。   Further, a support portion 56 is provided in the housing 52, and a plate spring 58 and a support plate 60 are disposed on the support portion 56 so as to face each other in the height direction X.
板バネ58は、図5(B)に示されるように、自由端58Aが回転カム54の回転操作によって押し上げられるようになっている。なお、板バネ58の基端は、支持部56によって支持されている。   As shown in FIG. 5B, the leaf spring 58 is configured such that the free end 58 </ b> A is pushed up by rotating the rotating cam 54. The base end of the leaf spring 58 is supported by the support portion 56.
支持板60は、板バネ58に対向して配置されており、板バネ58側の面に圧電部材26が複数(本実施形態では6つ)設けられている。なお、支持板60の基端は、支持部56によって支持されている。   The support plate 60 is disposed to face the plate spring 58, and a plurality of (six in this embodiment) piezoelectric members 26 are provided on the surface of the plate spring 58 side. The base end of the support plate 60 is supported by the support portion 56.
また、板バネ58の支持板60側の面には、圧電部材26に衝突する衝突部材62が設けられている。本実施形態の衝突部材62は、圧電部材26に対応した位置にそれぞれ設けられている。ここで、衝突部材62は、回転カム54の回転操作によって押し上げられた板バネの復元力によって圧電部材26と衝突するようになっている。圧電部材26によって発電された電流は整流回路34、電気配線38及び接続端子36を通して携帯端末100の充電部に供給されるようになっている。   A collision member 62 that collides with the piezoelectric member 26 is provided on the surface of the plate spring 58 on the support plate 60 side. The collision member 62 of the present embodiment is provided at a position corresponding to the piezoelectric member 26. Here, the collision member 62 collides with the piezoelectric member 26 by the restoring force of the leaf spring pushed up by the rotation operation of the rotary cam 54. The current generated by the piezoelectric member 26 is supplied to the charging unit of the portable terminal 100 through the rectifier circuit 34, the electric wiring 38 and the connection terminal 36.
次に、本実施形態の発電装置50の作用効果について説明する。   Next, the effect of the power generator 50 of this embodiment is demonstrated.
発電装置50では、携帯端末100を持った操作者が指を使って回転カム54を回転させる(回転操作する)ことで、板バネ58の自由端58Aが回転カム54のカム部54Aによって持ち上げられる(図5(B)参照)。そして、カム部54Aが自由端58Aから離れると、板バネ58が復元力によって元の状態に戻る。このとき、板バネ58に設けられた衝突部材62が支持板60に設けられた圧電部材26に衝突して圧電部材26が加圧される。圧電部材26は、加圧されることで、圧電効果によって発電する。このとき発電される電流は、パルス状であるが、整流回路34で平滑化され、電気配線38を通って、接続端子36から携帯端末100の充電部へ供給され、充電部が充電される。   In the power generation device 50, when the operator holding the mobile terminal 100 rotates (rotates) the rotating cam 54 with his / her finger, the free end 58 </ b> A of the leaf spring 58 is lifted by the cam portion 54 </ b> A of the rotating cam 54. (See FIG. 5B). When the cam portion 54A moves away from the free end 58A, the leaf spring 58 returns to the original state by the restoring force. At this time, the collision member 62 provided on the plate spring 58 collides with the piezoelectric member 26 provided on the support plate 60 and the piezoelectric member 26 is pressurized. The piezoelectric member 26 generates electric power by the piezoelectric effect when pressed. The current generated at this time is in a pulse form, but is smoothed by the rectifier circuit 34 and supplied to the charging unit of the portable terminal 100 from the connection terminal 36 through the electric wiring 38, and the charging unit is charged.
ここで、発電装置50では、携帯端末100を持ちながら、回転カム54を回転させる回転操作で携帯端末100の充電部に充電をすることができる。すなわち、発電装置20は、充電部を備えた携帯端末100に対して簡単な回転操作で充電をすることができる、という格別な効果を奏する。なお、携帯端末100の操作時などに回転カム54を回転操作することで携帯端末100の充電部に充電できるため、携帯端末100の充電回数を減らすことができる。さらに、携帯端末100用の専用充電器を持ち運ぶ必要がなくなる。   Here, the power generation apparatus 50 can charge the charging unit of the mobile terminal 100 by a rotating operation of rotating the rotary cam 54 while holding the mobile terminal 100. That is, the power generation device 20 has an exceptional effect that the mobile terminal 100 including the charging unit can be charged by a simple rotation operation. In addition, since the charging part of the portable terminal 100 can be charged by rotating the rotary cam 54 when the portable terminal 100 is operated, the number of times the portable terminal 100 is charged can be reduced. Furthermore, it is not necessary to carry a dedicated charger for the portable terminal 100.
また、発電装置50では、圧電部材26を複数設けているため、発電量を向上させることができる。   Further, since the power generation device 50 includes a plurality of piezoelectric members 26, the power generation amount can be improved.
(第3実施形態)
次に、本実施形態に係る発電装置70について図7に基づいて説明する。なお、本実施形態では、携帯端末100に発電装置70を装着している。
(Third embodiment)
Next, the power generation device 70 according to the present embodiment will be described with reference to FIG. In the present embodiment, the power generation device 70 is attached to the mobile terminal 100.
本実施形態の発電装置70は、装着部材の一例としてのハウジング72が携帯端末100を収容するケース74を含む構成が第1実施形態の発電装置70と異なる。発電装置70のその他の構成については、第1実施形態の発電装置20と同じであり、その説明を省略する。また、図面において、第1実施形態と同一の構成については同一符号を付す。   The power generation device 70 of the present embodiment is different from the power generation device 70 of the first embodiment in that a housing 72 as an example of a mounting member includes a case 74 that houses the mobile terminal 100. About the other structure of the electric power generating apparatus 70, it is the same as the electric power generating apparatus 20 of 1st Embodiment, The description is abbreviate | omitted. In the drawings, the same components as those in the first embodiment are denoted by the same reference numerals.
ハウジング72は、ケース74と一体成形されている。このハウジング72は、第1実施形態のハウジング22と同様の構成である。また、ケース74は、携帯端末100を収容するケースであり、接続部材28が内蔵されている。具体的には、ケース74の背面壁74Aの内側には、電気配線38が内蔵されており、ケース74の枠壁74Bからケース内側へ突出した接続端子36に電気配線38が接続されている。   The housing 72 is integrally formed with the case 74. The housing 72 has the same configuration as the housing 22 of the first embodiment. The case 74 is a case for housing the mobile terminal 100 and has the connection member 28 built therein. Specifically, the electrical wiring 38 is built inside the back wall 74A of the case 74, and the electrical wiring 38 is connected to the connection terminal 36 protruding from the frame wall 74B of the case 74 to the inside of the case.
次に、本実施形態の発電装置70の作用効果について説明する。なお、第1実施形態で得られる作用効果と同様の作用効果についてはその説明を適宜省略する。   Next, the effect of the power generator 70 of this embodiment is demonstrated. In addition, the description about the effect similar to the effect obtained in 1st Embodiment is abbreviate | omitted suitably.
本実施形態の発電装置70では、携帯端末100のケース74がハウジング72に含まれるため、例えば、携帯端末100用のケースに別途発電装置を装着する構成よりも、発電装置70の装着作業が容易である。また、ケース74内に電気配線38を通すため、例えば、電気配線38が外部にあるものと比べて、見栄えも、使いやすさも向上する。   In the power generation device 70 of this embodiment, the case 74 of the mobile terminal 100 is included in the housing 72. Therefore, for example, the mounting operation of the power generation device 70 is easier than the configuration in which the power generation device is separately mounted on the case for the mobile terminal 100. It is. Further, since the electric wiring 38 is passed through the case 74, for example, the appearance and usability are improved as compared with the case where the electric wiring 38 is provided outside.
なお、第3実施形態の構成については、第2実施形態に適用してもよい。すなわち、第2実施形態の発電装置50のハウジング52が携帯端末100を収容するケースを含む構成としてもよい。   Note that the configuration of the third embodiment may be applied to the second embodiment. That is, the housing 52 of the power generation device 50 according to the second embodiment may include a case that houses the mobile terminal 100.
また、第1実施形態の発電装置20のハウジング22と、第2実施形態の発電装置50のハウジング52とが携帯端末100を収容する同一のケースを含む構成としてもよい。言い換えると、一つのケースに発電装置20、50を設けてもよい。   Moreover, it is good also as a structure containing the same case in which the housing 22 of the electric power generating apparatus 20 of 1st Embodiment and the housing 52 of the electric power generating apparatus 50 of 2nd Embodiment accommodate the portable terminal 100. FIG. In other words, the power generation devices 20 and 50 may be provided in one case.
またさらに第1実施形態では、圧電部材26を圧電性セラミックで構成しているが、本発明はこの構成に限定されない。圧電部材26を圧電性フィルムで構成してもよい。なお、圧電性フィルムとしては、例えば、ポリフッ化ビニリデンをフィルム状に形成したものを用いてもよい。圧電部材26として圧電性フィルムを用いる場合、ハウジング22の側面22Aに収容凹部23を形成せずに、側面22Aに圧電性フィルムを貼り付ける構成としてもよい。これにより、ハウジング22の形状を簡単にできる。また、複数の圧電フィルムを貼り付けずに、一枚の圧電性フィルムを貼り付ける構成としてもよい。この場合には、圧電性フィルムを貼り付ける作業が簡単になる。さらに、ポリフッ化ビニリデンをフィルム状にした圧電性フィルムで圧電部材を構成することで、圧電部材を圧電性セラミックで構成する場合と比べて、10倍以上の高電圧出力を得ることができる。これにより、発電装置の発電効率がより向上する。
また、本発明における圧電部材を圧電性フィルムで構成することについては、第2実施形態の発電装置及び第3実施形態の発電装置に適用してもよい。
Furthermore, in the first embodiment, the piezoelectric member 26 is made of piezoelectric ceramic, but the present invention is not limited to this structure. The piezoelectric member 26 may be composed of a piezoelectric film. In addition, as a piezoelectric film, you may use what formed the polyvinylidene fluoride in the film form, for example. When a piezoelectric film is used as the piezoelectric member 26, the piezoelectric film may be attached to the side surface 22A without forming the housing recess 23 on the side surface 22A of the housing 22. Thereby, the shape of the housing 22 can be simplified. Alternatively, a single piezoelectric film may be attached without attaching a plurality of piezoelectric films. In this case, the work of attaching the piezoelectric film is simplified. Furthermore, by forming the piezoelectric member with a piezoelectric film made of polyvinylidene fluoride in the form of a film, it is possible to obtain a high voltage output that is 10 times higher than when the piezoelectric member is made of a piezoelectric ceramic. Thereby, the power generation efficiency of the power generation device is further improved.
Moreover, you may apply to the electric power generating apparatus of 2nd Embodiment and the electric power generating apparatus of 3rd Embodiment about comprising the piezoelectric member in this invention with a piezoelectric film.
以上、本発明の一実施形態について説明したが、本発明は、上記に限定されるものでなく、その主旨を逸脱しない範囲内において上記以外にも種々変形して実施することが可能であることは勿論である。   Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and various modifications other than the above can be implemented without departing from the spirit of the present invention.
