In the conventional power generation device, charge is output when moving the starting unit from the start point to the end point. However, in the conventional power generation device, the charge can not be output when the activation unit returns from the end point to the start point.

  On the other hand, the power generation device 11 of the present disclosure can output the charge even when the activation unit returns from the end point to the start point.

  Hereinafter, an embodiment of a power generation device of the present disclosure and a configuration of an electronic device including the power generation device of the present disclosure will be described with reference to the drawings. In addition, the component which attached the same code | symbol in the following description performs the same operation | movement. Corresponding elements may be denoted by the same reference numerals and redundant description may be omitted.

  Here, prior to describing the power generation device 11 of the present disclosure, an electronic device 15 that operates by energy harvesting will be described.

[Overview of Electronic Device 15]
FIG. 7A is a conceptual view of the electronic device 15. 7B to 7D are diagrams showing the electronic device 15 of FIG. 7A as an equivalent circuit. Hereinafter, the electronic device 15 will be described with reference to FIGS. 7A to 7D. An example of the electronic device 15 is a remote control. The electronic device 15 includes an operation unit 151, a signal processing circuit 153, a power supply circuit 154, a transmission unit 156, and the power generation device 100.

  When the operator operates the operation unit 151, the power generation device 100 can generate electric power. The electric power generated by the power generation device 100 is supplied from the output terminal 22A or the output terminal 22B to the power supply circuit 154 via the output terminal 22. Then, power is supplied from the power supply circuit 154 to the signal processing circuit 153. That is, the signal processing circuit 153 is driven by the power generated by the power generation apparatus 100.

  The power generation apparatus 100 outputs power in response to the operation of the operator. Therefore, the power generation device 100 can detect whether the operator (not shown) has operated the operation unit 151. When the power generation device 100 detects that the operation unit 151 is operated, the signal processing circuit 153 in the electronic device 15 can output a detection signal. The power generation device 11 can also serve as a sensor that detects whether the operation unit 151 has been operated.

  The detection signal is input to the signal processing circuit 153. Then, the signal processing circuit 153 can detect whether the operation unit 151 has been operated by the detection signal. Therefore, the signal processing circuit 153 operates with the power generated by the power generation apparatus 100 and detects the operation of the operator. The signal processing circuit 153 outputs the detection signal S1 to the transmitting unit 156 in this manner. Even when the power supply circuit 154 and the signal processing circuit 153 are in a non-operating state, a leak current flows in the electronic device 15. That is, even if the power supply circuit 154 or the signal processing circuit 153 is not operating, the electronic device 15 consumes power.

  On the other hand, when the operation unit 151 is operated, the power generation device 100 can output only limited power. Therefore, for example, when the operator long presses the operation unit 151, the power generated by the operation of pressing the operation unit 151 is consumed before the long press operation is completed.

  Therefore, the inventors of the present application focused on the power generation device capable of outputting electric power when the operator cancels the operation of pressing the operation unit 151.

  Next, an embodiment of the present disclosure will be described.

Embodiment 1
FIG. 1A is a cross-sectional view of the power generator 11 at 1A-1A in FIG. FIG. 1B is a cross-sectional view of the power generation device 11 in 1B-1B of FIG. FIG. 2 is a top view of the power generation device 11. FIG. 3 is an exploded perspective view of the power generation device 11.

  It demonstrates using the electric power generating apparatus 11 used for the electronic device 15 (refer FIG. 7A) etc. which are driven by energy harvesting (environmental power generation) etc., and generates electric power by vibration. Hereinafter, description will be made with reference to FIGS. 1A to 3. The configuration incorporated in the electronic device 15 of the power generation device 11 is the same as that of the power generation device 100 described above (see FIG. 7A).

  The power generation device 11 includes a case 81, an input terminal 21, an output terminal 22A, an output terminal 22B, a power generation unit 31, a moving member 41, and a switch unit 61. The input terminal 21, the output terminal 22A, the output terminal 22B, the power generation unit 31, the moving member 41, and the switch unit 61 are housed in a case 81. A part of the output terminal 22A and a part of the output terminal 22B are formed so as to protrude or be exposed to the outside from the case 81.

  In FIGS. 1A and 1B, although the middle terminal 311 and the input terminal 21 and the middle terminal 311 are not illustrated as being projected from the case 81 to the outside, they are protruding to the outside of the case 81 or the case It is formed to be able to connect from the outside of 81.

  As shown in FIGS. 1B and 3, the switch 61 includes a contact 621, a contact 622, and a contact 623. Hereinafter, the contact portion 621, the contact portion 622, and the contact portion 623 may be collectively referred to as "a plurality of contact portions 62". Further, the contact portion 621 includes an adjustment portion 6211 and an adsorber 6212.

[Summary of operation of power generation unit 31]
First, the operation of the power generation unit 31 will be briefly described. The power generation unit 31 generates power by vibration. The moving member 41 can be moved in the first direction (shown as “A” in the drawing) from the start point to the end point by the operation of the operator. The moving member 41 functions as an activation unit of the power generation device 11. Hereinafter, the first direction is referred to as “direction A”. Then, when the moving member 41 moves in the direction A, the power generation unit 31 bends. When the moving member 41 further moves in the direction A, the power generating unit 31 starts to vibrate as the power generating unit 31 separates from the moving member 41. The electric power generated by the vibration of the power generation unit 31 is output from an intermediate terminal 311 provided at an end of the power generation unit 31.

  The flow of power will now be described with reference to FIGS. 1A, 7B, 7C and 7D. When the power generation unit 31 starts to vibrate, power generated by the power generation unit 31 is input from the intermediate terminal 311 to the rectification circuit 72 and input to the input terminal 21 as shown in FIG. 7C. When the power generation unit 31 starts to vibrate, the switch unit 61 selects the output terminal 22A. At this time, power is input from the output terminal 22A to the signal processing circuit 153 through the output terminal 22 and the power supply circuit 154. And according to the position of the moving part 41, as shown to FIG. 7B, the switch part 61 switches so that the output terminal 22B may be selected. At this time, power is input from the output terminal 22 B to the signal processing circuit 153 through the output terminal 22 and the power supply circuit 154. Furthermore, as shown in FIG. 7D, the switch unit 61 shifts to a state in which both the output terminal 22A and the output terminal 22B are not in contact by the movement of the moving unit 41.

  The switch unit 61 does not contact both the output terminal 22A and the output terminal 22B even while the connection is switched from the output terminal 22A to the output terminal 22B.

  The details of the operation of the power generation unit 31 starting the vibration will be described later with reference to FIGS. 5A to 5F.

[Overview of Operation of Contact 62]
Next, the operation of the contact portion 62 will be briefly described. The moving member 41 functions as a mechanism for switching the connection of the plurality of contact portions 62. The moving member 41 repeats the movement in the direction A and the movement in the direction B, which is the direction opposite to the direction A. That is, the moving member 41 reciprocates linearly in the vertical direction in FIG. 1A.

  Hereinafter, the position of the start point of the movable member 41 is referred to as “first position”, and the position of the end point of the movable member 41 is referred to as “second position”. In addition, moving the moving member 41 at the second position in the direction B may be described as “returning the moving member 41 from the end point to the start point”.

  When the moving member 41 in the first position moves in the direction A, the power generation unit 31 bends in the direction A, and the contact portion 621 also bends in the direction A. When the moving member 41 bends the contact portion 621 in the direction A, the contact portion 621 contacts the contact portion 622 (see FIG. 6B). When the power generation unit 31 starts power generation, the contact portion 621 is separated from the contact portion 623. At this time, the contact portion 621 remains connected to the contact portion 622 (see FIG. 6D). That is, when the moving member 41 moves in the direction A, the contact portion 621 is electrically separated from the contact portion 623, and the contact portion 621 contacts the contact portion 622. At this time, a signal (or power or the like) supplied to the input terminal 21 is supplied to the contact portion 622 through the contact portion 621 (see FIG. 6D).

  Next, when the moving member 41 moves from the second position to the first position (moves in the direction B), a signal (or power or the like) input from the input terminal 21 is supplied to the contact portion 623 ( See FIG. 6A).

  That is, the power generation device 11 of the present disclosure can selectively output the signal (or the electric power or the like) supplied to the input terminal 21 to the contact portion 622 or the contact portion 623.

  The details of the operation of the contact portion 62 will be described later with reference to FIGS. 6A to 6F.

[Operation of Electronic Device 15]
Next, the operation of the electronic device 15 will be described with reference to FIGS. 1A, 1B and 7A to 7D.

  The electronic device 15 has an output terminal 22. In the electronic device 15 of the present disclosure, the output terminal 22 includes the output terminal 22A and the output terminal 22B. In addition, the switch unit 61 can switch to selectively supply power to any one of the output terminal 22A and the output terminal 22B by the movement of the moving member 41. The switch unit 61 supplies the power generated by the power generation unit 31 to the output terminal 22A for a certain period. FIG. 7B shows a state in which the power generated by the power generation unit 31 is supplied to the output terminal 22B. FIG. 7C shows a state in which the power generated by the power generation unit 31 is supplied to the output terminal 22A. FIG. 7D shows a state in which the power generated by the power generation unit 31 is not supplied to either the output terminal 22A or the output terminal 22B. In addition, the switch unit 61 stops the supply of power to the output terminal 22A after the specified time has elapsed. Thereafter, power is supplied to the output terminal 22B by returning the moving member 41 in the second direction (direction B).

  As described above, by moving the moving member 41 in the first direction (direction A), the power generation unit 31 can generate power, and the power generated by the power generation unit 31 can be output from the output terminal 22A. Further, by moving the moving member 41 in the second direction (direction B), power can be output from the output terminal 22B. Therefore, the power generated by the power generation unit 31 can be selectively output to the output terminal 22A and the output terminal 22B. The power output from the output terminal 22 will be described in detail later with reference to the signal waveform diagram shown in FIG.

  The signal processing circuit 153 illustrated in FIG. 7A includes a terminal 1531A, a terminal 1531B, and a terminal 1532. The output terminal 22A and the output terminal 22B are electrically connected to the power supply circuit 154. The terminal 1532 is a power supply terminal of the signal processing circuit 153. Therefore, the output of the power supply circuit 154 is connected to the terminal 1532. With this configuration, the electric power generated by the power generation device 11 is supplied to the terminal 1532 via the power supply circuit 154. Therefore, the signal processing circuit 153 operates with the power generated by the power generation device 11. FIGS. 7B to 7D illustrate the connection between the power generation unit 31, the intermediate terminal 311, the input terminal 21, the output terminal 22A, and the output terminal 22B in the power generation device 11 illustrated in FIG. 7A more clearly.

  Furthermore, the electric power generated by the power generation device 11 is supplied as a detection signal to the terminal 1531A and the terminal 1531B. The terminal 1531A receives the output from the output terminal 22A. On the other hand, the terminal 1531B receives the output from the output terminal 22B. That is, a signal for the signal processing circuit 153 to detect depression of the operator is input to the terminal 1531A. A signal for the signal processing circuit 153 to detect push-back is input to the terminal 1531B. A signal is output from the output terminal 22A to the terminal 1531A. On the other hand, a signal is output from the output terminal 22B to the terminal 1531B. With this configuration, the signal processing circuit 153 shown in FIGS. 7A to 7D can detect the pressing-down operation of the operator by the output from the output terminal 22A. Further, the signal processing circuit 153 illustrated in FIGS. 7A to 7D can detect the push-back operation of the operator after the operator has long-pressed the operation unit 151 by the output from the output terminal 22B.

  As described above, the power generated by the power generation unit 31 is output from the output terminal 22A or the output terminal 22B with different timings by switching the switch unit 61. As shown in FIGS. 7A to 7D, the signal processing circuit 153 has two terminals 1531A and 1531B, but the present invention is not limited to this configuration. The electronic device 15 may have only the terminal 1531A. In this case, the output from the output terminal 22A and the output from the output terminal 22B are both supplied to the terminal 1531A. Then, the signal processing circuit 153 can detect the operation of the operator based on the difference in the timing of the input signal. In addition, for that purpose, the output terminal 22 combines and outputs the output of the output terminal 22A and the output terminal 22B.

  As illustrated in FIGS. 7A to 7D, the power generation device 11 includes a rectifier circuit 72. The rectifier circuit 72 is inserted between the input terminal 21 and the power generation unit 31. The rectification circuit 72 may be any rectification method such as half wave rectification or full wave rectification. The power generation device 11 further includes a capacitor 71. In this case, the capacitor 71 is inserted between the input terminal 21 and the rectifier circuit 72. That is, the capacitor 71 is electrically connected to the input terminal 21 and the rectifier circuit 72. The capacitor 71 stores the output power of the rectifier circuit 72. Furthermore, the capacitor 71 supplies the stored power to the input terminal 21.

  With this configuration, the power generated by the power generation unit 31 or the power stored in the capacitor 71 can be selectively output to either the contact portion 622 or the contact portion 623 (one of the output terminal 22A and the output terminal 22B). . Then, by moving the moving member 41 in the second direction, the power stored in the capacitor 71 is supplied to the contact portion 623 (output terminal 22B). As a result, even if the moving member 41 is moved in the second direction (direction B) while the operator has completed power generation (the state where power generation is not generated from the power generation unit 31), the output terminal 22B Can output power from In addition, when the circuit is electrically connected to the contact portion 621 or the contact portion 622, in a state where the moving member 41 is held at the end position, the current to the connected circuit (signal processing circuit 153) Can be suppressed. Therefore, the occurrence of the leakage current in the signal processing circuit 153 can be suppressed. As a result, it is possible to suppress wasteful consumption of the power generated by the power generation unit 31 due to the leak current in the signal processing circuit 153, the standby current in the signal processing circuit 153, and the like.

[Details of Configuration of Generator 11]
Hereinafter, the power generation device 11 will be described in more detail with reference to FIGS. 1A to 3 and 7A to 7D.

  The power generation unit 31 generally includes a piezoelectric element (not shown). The intermediate terminal 311 is connected to the power generation unit 31. The power generation unit 31 has a piezoelectric film formed on a cantilevered metal plate. The power generation unit 31 outputs the generated power from the intermediate terminal 311 by vibrating the piezoelectric element (see FIG. 1A).

  The input terminal 21 is electrically connected to the contact portion 621. The input terminal 21 is provided at one end of the contact portion 621. The output terminal 22A is electrically connected to the contact portion 622. The output terminal 22A is provided at one end of the contact portion 622. The output terminal 22B is electrically connected to the contact portion 623. The output terminal 22 B is provided at one end of the contact portion 623. The other end of the contact portion 621 is disposed so as to be in contact with the other end of the contact portion 623. Further, the other end of the contact portion 622 is disposed so as to be in contact with the middle point portion of the contact portion 621.

[Details of configuration of power generation unit 31 and contact unit 62]
Next, the power generation unit 31 and the contact unit 62 will be described in more detail with reference to FIGS. 5A to 7D.

<Start status>
5A and 6A show the state when the moving member 41 is positioned at the start point.

  In FIG. 5A, the adsorber 312 and the adsorber 411 adsorb. In this state, the power generation unit 31 does not vibrate and does not generate power. As shown in FIG. 6A, at this time, the contact portion 621 is in contact with the contact portion 623 and the contact portion 621 is separated from the contact portion 622. At this time, the input terminal 21 is connected to the output terminal 22B by the switch unit 61 (state shown in FIG. 7B).

<Startup state>
Next, as shown in FIG. 5B, when the moving member 41 is lowered toward the first direction (direction A), the power generation unit 31 abuts on the peeling portion 811 (see FIG. 5C) and adsorbs with the adsorber 312. The body 411 is separated, and the power generation unit 31 starts to vibrate (see FIG. 5D). Electric power generated by vibration of the power generation unit 31 is output from the intermediate terminal 311. The generated power is input to the capacitor 71 and the input terminal 21 through the rectifier circuit 72.

  On the other hand, in the contact portion, when the moving member 41 is lowered in the first direction (indicated as “A” in FIG. 6B), the contact portion 621 abuts on the contact portion 622 (see FIG. 6B). Furthermore, the moving member 41 is lowered toward the first direction, the contact portion 621 abuts on the peeling portion 811 (see FIG. 6C), and the adsorber 6212 and the adsorber 411 separate. At this time, the contact portion 621 and the contact portion 622 are still in contact with each other (see FIG. 6D).

  That is, when the power generation unit 31 starts power generation, the contact portion 621 switches from being in contact with the contact portion 622 to being in contact with the contact portion 623. At this time, the input terminal 21 is switched by the switch unit 61 so as to be connected to the output terminal 22A (state shown in FIG. 7C).

<Power supply stop period>
Next, when the moving member 41 maintains the position at the end point (second position), the contact portion 621 gradually rises upward (direction B). As a result, as shown in FIG. 6E, the contact portion 621 is electrically separated from the contact portion 622 and the contact portion 623.

  At this time, by switching the switch unit 61, the supply of power from the input terminal 21 to the output terminal 22A and the output terminal 22B is stopped. That is, while the operator holds (maintains) the moving member 41 at the end position, the contact portion 621 is not connected to either the contact portion 622 or the contact portion 623. That is, since the signal and the power input to the input terminal 21 are not supplied to any of the contact portions 622 and 623, the power generated by the power generation unit 31 is accumulated in the capacitor 71. That is, the switch unit 61 is in the state shown in FIG. 7D.

<Return status>
Next, as shown in FIG. 6F, when the moving member 41 is moved in the direction B, the input terminal 21 is connected to the output terminal 22B by the switch unit 61, and the state is switched to the state of FIG. 7B. Thus, the power stored in the capacitor 71 is supplied to the output terminal 22B.

  As a result, even after the generation of power from the power generation unit 31 stops, when the moving member 41 is moved in the direction B, power can be supplied from the output terminal 22B to the signal processing circuit 153.

  As apparent from the above description, in the power generation device 11 of the present disclosure, when the moving member 41 moves in the second direction (direction B), the signal (or power or the like) is generated without generating power again. , And can be supplied to the output terminal 22B via the contact portion 623 (third contact portion). That is, even when the moving member 41 moves in the B direction, a signal (or power or the like) can be supplied to the output terminal 22B without providing a mechanism for vibrating the power generation unit 31 or the like. Therefore, there is no need to provide a mechanism or the like for vibrating the power generation unit 31 for generating power when the moving member 41 moves in the direction B. Therefore, miniaturization of the power generation device 11 can be realized.

  That is, in the power generation device 11 of the present disclosure, the signal supplied to the input terminal 21 can be selectively output to the contact portion 622 and the contact portion 623. When the moving member 41 is moved in the first direction (direction A), the signal supplied to the input terminal 21 is supplied to the contact portion 622 (output terminal 22B). On the other hand, when the moving member 41 returns from the end point to the starting point (when the moving member 41 is moved in the direction B), the signal supplied to the input terminal 21 is supplied to the contact portion 623.

  As a result, even when the moving member 41 returns from the end point to the start point, the power generated by the power generation unit 31 can be supplied from the capacitor 71 to the input terminal 21, and the power generation device 11 can provide power.

  Furthermore, when the moving member 41 is held at the end position (second position), the switch unit 61 does not supply power from the input terminal 21 to the output terminal 22A and the output terminal 22B. A current can be prevented from flowing to a circuit (for example, the signal processing circuit 153) connected to the output terminal 22A and the output terminal 22B. Therefore, no leak current occurs in the circuit. In other words, it is possible to suppress that a certain amount of electric power generated by the power generation unit 31 is consumed by the leak current.

  The moving member 41 preferably moves by adsorbing the power generation unit 31 by magnetic force. As described above, in the power generation device 11 of the present disclosure, the moving member 41 causes the power generation portion 31 to bend by adsorbing the power generation portion 31 by the magnetic force. Since the power generation unit 31 is bent by the magnetic force, it is not necessary to newly provide a link mechanism or the like for driving the moving member 41. Further, since the magnetic force is used, even when the moving member 41 is repeatedly operated, it is possible to suppress the occurrence of wear of the moving member 41 which occurs when using the link configuration. As a result, even if the moving member 41 is operated repeatedly, it is possible to reduce the change of the amplitude of the power generation unit 31 or the like. That is, the power generated by the power generation unit 31 can be stabilized.

  Furthermore, the moving member 41 can move the power generation unit 31 from the end point (second position) to the second direction (direction B) by attracting the power generation unit 31 by the attraction force of the magnetic force. it can. In this case, the moving member 41 also functions as a return unit. That is, the moving member 41 can double as part or all of the return part. For example, in the case where the moving member 41 doubles as the entire return part, it is not necessary to provide a return spring or the like that functions as the return part. Therefore, the moving member 41 can move with a small force.

[Modification of return part]
Here, the configuration in which the return spring 200 is provided on the moving member 41 as the return portion will be briefly described with reference to FIG.

  When the moving member 41 doubles as a part of the returning part or when it does not serve as the returning part, the returning spring 200 may be provided to the moving member 41 as the returning part. For the return spring 200 shown in FIG. 12, it is preferable to use a push spring that utilizes a repulsive force that is about to return against a force that is compressed.

  First, after the moving part moves from the first position to the second position, the return spring 200 biases the moving member 41 in the second direction (direction B). In the case where the moving member 41 doubles as a part of the return part, that is, when the attraction force of the magnetic force is working between the moving member 41 and the power generation unit 31, the moving member 41 by the return spring 200 is in the second direction. The elastic force for biasing can be reduced by the attraction of the magnetic force. Therefore, the moving member 41 can move with a small force.

  Similarly to the power generation unit 31, the return spring 200 can be used for the contact portion 621. In the power generation device 11 of the present disclosure, the moving member 41 moves by being attracted to the contact portion 621 by the magnetic force. When the moving member 41 is attracted to the contact portion 621 by the magnetic force, the moving member 41 bends the power generation unit 31. At the same time as the moving member 41 bends the contact portion 621, the power generation unit 31 also bends.

  As in the power generation device 11 of the present disclosure, when using a magnetic force, the adsorber 411 is disposed on the moving member 41 (see, for example, FIG. 5A and FIG. 6A). When the metal plate of the power generation unit 31 is formed of a magnetic material, a magnet is preferably used as the adsorber 411. When a magnet is used as the adsorbing member 411, the contact portion 621 is formed of a magnetic material. When the power generation unit 31 and the contact unit 621 are nonmagnetic materials such as stainless steel, an adsorber 312 or an adsorber 6212 formed of a magnetic material is provided (for example, see FIGS. 5A and 6A). The adsorber 312 is disposed on the free end side of the power generation unit 31 so as to face the adsorber 411. On the other hand, the adsorber 6212 is disposed on the free end side of the contact portion 621 so as to face the adsorber 411.

  The adsorber 312 and the adsorber 6212 are not limited to the magnetic material but may be magnets. However, in this case, the magnetic poles of the adsorber 312 and the adsorber 6212 are arranged to face in the opposite direction to the magnetic pole of the adsorber 411. That is, since the opposite magnetic poles are disposed to face each other, the moving member 41 is attracted to the power generation unit 31 and the contact portion 621 by the attraction force. In addition, although the magnet was used for adsorber 312, adsorber 6212, and adsorber 411 in power generator 11 of this indication, it does not restrict to this composition. The adsorber 312 and the adsorber 6212 may be formed of a magnet, and the adsorber 411 may be formed of a magnetic material.

[Configuration of Peeling Section 811]
Next, a configuration for separating the power generation unit 31 and the contact portion 621 from the moving member 41 will be described with reference to FIGS. 5A to 6F. The case 81 has a peeling portion 811. When the moving member 41 is pushed down, the tip of the peeling portion 811 abuts on the power generation portion 31 as shown in FIG. 5C. Similarly, as shown in FIG. 6C, the tip of the peeling portion 811 abuts on the contact portion 621. By arranging the peeling portion 811, the power generation portion 31 and the contact portion 621 can prevent the power generation portion 31 and the contact portion 621 from further bending after coming into contact with the peeling portion 811. The end point (second position) of the moving member 41 is located below the position of the moving member 41 when the tip of the peeling portion 811 and the power generation unit 31 or the contact portion 621 abut. Even if the power generation unit 31 or the contact portion 621 stops moving in the first direction (direction A), the moving member 41 further moves toward the end point (second position). Therefore, substantially simultaneously with the contact of the power generation unit 31 or the contact portion 621 with the tip of the peeling portion 811, the power generation unit 31 or the contact portion 621 separates from the moving member 41. Then, by moving the moving member 41 to the end point (second position), the moving member 41 is disposed below the tip of the peeling portion 811. Therefore, after the peeling portion 811 abuts on the power generation unit 31, the power generation unit 31 separates from the moving member 41. Then, the power generation unit 31 starts to vibrate due to the deflection stored in the power generation unit 31 until then. Further, after the peeling portion 811 abuts on the contact portion 621, the contact portion 621 is separated from the moving member 41. That is, the contact portion 623 is electrically separated from the contact portion 621. In the power generation device 11 of the present disclosure, the timing of contacting the power generation unit 31 of the peeling portion 811 and the timing of contacting the contact portion 621 of the peeling portion 811 are simultaneous. Therefore, the timing when the power generation unit 31 starts to vibrate and the timing when the contact portion 621 and the contact portion 623 are electrically separated can be simultaneously performed. As a result, the power generated by the power generation unit 31 can be prevented from being supplied to the contact portion 623.

  The contact portion 621 is formed of an elastic material. The contact portion 621 is a cantilever. That is, the input terminal 21 side of the contact portion 621 is fixed. The side opposite to the input terminal 21 of the contact portion 621 is a free end. Therefore, the movement of the moving member 41 causes the free end side of the contact portion 621 to bend. That is, the contact portion 621 is regulated by the moving member 41 in a state where the reaction force due to the bending is accumulated. Then, the moving member 41 disengages from the contact portion 621 while moving from the start point to the end point. That is, the contact portion 621 is in a state of being separated from the moving member 41 at the end point of the moving member 41. Then, the contact portion 621 is released from the restriction by the moving member 41 by the detachment of the moving member 41. The contact portion 621 moves in the second direction (direction B) by the accumulated reaction force. As a result, the contact portion 621 is electrically separated from the contact portion 622.

  As apparent from the above description, the contact portion 621 and the contact portion 622 are separated at the end point (second position), and the reaction force accumulated in the contact portion 621 by the movement of the moving member 41 is used. That is, the contact portion 621 itself constitutes a mechanism for separating the contact portion 621 from the contact portion 622. Therefore, it is not necessary to separately provide a mechanism for separating the contact portion 621 and the contact portion 622 from each other.

  When the power generation unit 31 is activated by the magnetic force, it is preferable that the contact portion 621 is also connected to the contact portion 622 by a magnetic attraction force. In this case, in order to bend the contact portion 621 together with the power generation portion 31, the adsorber 411 can be diverted. When the adsorbing body 411 is a magnet, the contact portion 621 is preferably formed of a magnetic material. As another method, the contact portion 621 may be provided with an adsorber made of a magnet or a magnetic material. When the adsorber 411 is formed of a magnetic material, the adsorber of the contact portion 621 is preferably formed of a magnet. The adsorber 411 and the adsorber 6212 are disposed such that the adsorber 411 and the adsorber 6212 of the contact portion 621 face each other.

  Moreover, in the electric power generating apparatus 11 of this indication, in order to bend the contact part 621 and the electric power generation part 31 simultaneously, although the adsorbing body 411 was diverted, it does not restrict to this structure. In order to bend the contact portion 621, a dedicated adsorber may be provided on one or both of the contact portion 621 and the moving member 41.

[Configuration of Adjustment Unit 6211]
Next, the adjustment unit 6211 will be described with reference to FIGS. 6A to 6F.

  The contact portion 621 preferably includes an adjustment portion 6211. The adjustment unit 6211 is provided to adjust the contact time of the contact portion 621 and the contact portion 622. By adjusting the adjustment unit 6211, the time during which the contact portion 621 and the contact portion 622 are in contact can be adjusted. For example, the case where the adjustment unit 6211 is configured by a weight will be described. As the weight of the weight of the adjustment unit 6211 is heavier, it is possible to delay the time in which the contact portion 621 returns upward after the contact portion 621 and the moving member 41 (contact portion 623) are separated. On the other hand, if the weight of the adjustment portion 6211 is light, after the contact portion 621 and the moving member 41 (contact portion 623) are separated, the time for the contact portion 621 to return upward as compared to the case where the weight is heavy , Can be early. That is, the adjustment unit 6211 can appropriately adjust the time for which the signal and the power input to the input terminal 21 are supplied to the contact portion 622.

  In the present embodiment, the contact portion 623 is formed on the moving member 41. In this case, the detachment of the movable member 41 from the power generation unit 31 and the detachment of the movable member 41 from the contact portion 621 have the same timing. Therefore, the contact portion 621 (first contact portion) can be electrically separated from the contact portion 623 (third contact portion) at the same time as the power generation unit 31 starts power generation. Therefore, the power generated by the power generation unit 31 can be prevented from being supplied to the contact portion 623. In addition, the adjustment part 6211 can be comprised by the weight provided, for example in the other end of the contact part 621 as it mentioned above. In this case, by appropriately setting the weight of the weight, the time during which the contact portion 621 and the contact portion 622 are in contact can be adjusted.

[Output from generator 11]
Next, the state of the output of the electric power which generate | occur | produces from the electric power generating apparatus 11 is demonstrated in detail, referring FIG.2, FIG.4, FIG.5A-FIG.5F, FIG.6A-FIG.6F and FIG.7A-7D.

  FIG. 4 is a signal waveform diagram in the power generation device 11. The horizontal axis in FIG. 4 indicates time. In FIG. 4, the moving member 41 is pushed down at a constant speed (moved to the second position), and the moving member 41 is returned to the original position (returned to the first position). The state of the signal output from the power generation device 11 of FIG.

  The horizontal axis in FIG. 4 can be said to indicate the position of the moving member 41 shown in FIG. 1A. In FIG. 4, S <b> 31 shows an example of the output voltage characteristic after the power generated by the power generation unit 31 is rectified by the rectification circuit 72. S22A shows the voltage characteristic of the output terminal 22A. S22B shows the voltage characteristic of the output terminal 22B. S22 shows the voltage characteristic of the output terminal 22. That is, S22 is a combined output of S22A and S22B.

  5A to 5F and 6A to 6F are operation explanatory diagrams of the main parts of the power generation device 11. 5A to 5F show a state in which the power generation device 11 is cut along the section line 1A-1A shown in FIG. 6A to 6F show a state in which the power generation device 11 is cut along the section line 1B-1B shown in FIG. Hereinafter, the power generation operation and the output operation in the power generation device 11 will be described in detail with reference to FIGS. 4, 5A to 5F, 6A to 6F and 7A to 7D. The description of this operation will be made along with the change with time of the signal waveform shown in FIG.

  An operation diagram of the power generation unit 31 and the switch unit 61 at time T0 illustrated in FIG. 4 is illustrated in FIGS. 5A and 6A. That is, as shown in FIG. 4, this is a state before the operator operates the operation unit 151 (see FIG. 7A). The moving member 41 is located at the starting point (first position). The contact portion 621 is in contact with the contact portion 623. In this state, the moving member 41 is adsorbed to the power generation unit 31. At time T0, the power generation unit 31 is not vibrating. That is, the power generation unit 31 does not generate power. On the other hand, as shown in FIG. 6A, the contact portion 621 is not in contact with the contact portion 622. Therefore, the power generated by the power generation unit 31 can be suppressed from being output from the contact portion 622 or the contact portion 623.

  FIGS. 5B and 6B show operation diagrams of the power generation unit 31 and the switch unit 61 from time T0 shown in FIG. 4 to immediately before time T1. During a period from time T0 to time T1, the moving member 41 pushes the power generation unit 31 downward. In a period from time T0 to immediately before time T1, the moving member 41 is attracted to the power generation unit 31. Further, the contact portion 621 and the contact portion 623 are in contact with each other because the moving member 41 and the contact portion 621 are attracted to each other. As the moving member 41 moves in the direction A, the deflection of the power generation unit 31 and the contact portion 621 increases. Then, by the time the time T1 is reached, the contact portion 621 contacts the contact portion 622 (see FIG. 6B). At this time, the power generation unit 31 is suppressed in vibration. That is, substantially no power is generated in the power generation unit 31, and no power is supplied to the contact portions 622 and 623.

  An operation diagram at time T1 shown in FIG. 4 is shown in FIGS. 5C and 6C. FIG. 5C and FIG. 6C show the state in which the moving member 41 is located at the separation point. At this point, the power generation unit 31 and the contact portion 621 abut on the peeling portion 811. The moving member 41 can move further in the end point direction (direction A) beyond the separation point. Therefore, when the operator continues to push beyond the release point, the moving member 41 moves in the end point direction (direction A) more than the contact portion of the peeling portion 811 with the vibrating portion. In this state, the adsorption state between the power generation unit 31 and the moving member 41 is released. At the same time, the attracted state between the contact portion 621 and the moving member 41 is released. The moving member 41 separates from the power generation unit 31 and the contact unit 621. Thereby, the contact between the contact portion 621 and the contact portion 623 is also released. Further, the reaction force stored by the deflection of the power generation unit 31 due to the movement of the moving member 41 is released. Therefore, the vibration of the power generation unit 31 is started immediately after time T1 to start power generation (see FIG. 5D). Further, the detachment of the power generation unit 31 from the moving member 41 and the detachment of the contact portion 621 from the moving member 41 occur at the same timing. Then, the vibration of the power generation unit 31 starts at time T1 and gradually attenuates. Then, the power generation unit 31 vibrates and outputs power until time T2 (see the characteristic curve S31 in FIG. 4).

  When the power generation by the power generation unit 31 is started, the power generated by the power generation unit 31 is stored in the capacitor 71 via the rectification circuit 72. At this time, power is supplied from the input terminal 21 to the output terminal 22A in the state shown in FIG. 7C in the switch unit 61 configured by the contact units 621 to 623. The contact portion 621 is in contact with the contact portion 622 in a state where the moving member 41 is located at the separation point (the state shown in FIG. 6C).

  Then, when the moving member 41 passes through the separation point, the contact between the contact portion 621 and the contact portion 623 is eliminated. At this time, the contact state between the contact portion 621 and the contact portion 622 is continued. By this configuration, the voltage supplied to the output terminal 22A starts to rise immediately after time T1.

  Further, immediately after the time T1, the contact portion 621 is released from the suction with the moving member 41. Therefore, at this time, the reaction force accumulated by the bending of the contact portion 621 is released. Then, the contact portion 621 starts moving in the second direction (direction B). However, since the contact portion 621 is provided with the adjustment portion 6211 (in the present disclosure, a weight), the contact portion 621 slowly returns in the second direction. During this time, the contact portion 621 is in contact with the contact portion 622 (see FIG. 6D).

  An operation diagram immediately after time T3 (second time) shown in FIG. 4 will be described. In a period from time T1 to time T3 (hereinafter, a period from time T1 to time T3 is referred to as “period T4”), the contact portion 621 is in contact with the contact portion 622 (see FIG. 6D). Then, immediately after the time T3 in FIG. 4, the contact portion 621 is released from contact with the contact portion 622 and is electrically separated (see FIG. 6E). That is, during the period T4, as shown in FIG. 7C, the power supplied to the input terminal 21 is output to the output terminal 22A as shown in FIG. 7C. Immediately after time T3, the state of the switch unit 61 shifts to FIG. 7D, and the supply of power from the input terminal 21 to the output terminal 22A is stopped.

  Operation diagrams at time T5 and time T6 shown in FIG. 4 are shown in FIGS. 5E and 6E. The moving member 41 reaches the end point (second position) at time T5. In the present embodiment, the operator keeps pressing (long pressing) the operation unit 151 shown in FIG. 7A for a long time (from time T5 to time T6). During this time, the moving member 41 is located at the end point. That is, the moving member 41 and the power generation unit 31 are separated, and the moving member 41 does not buffer the power generation unit 31. In the case where the operator does not press and hold the operation unit 151 and immediately returns after pushing down, there is almost no second time between time T5 and time T6.

  Further, in the present embodiment shown in FIG. 4, the adjustment unit 6211 adjusts the time so that the time T5 comes after the time T3 (second time), but the present invention is not limited to this configuration. Time T3 (second time) may be after time T5.

  The operator keeps pushing the operation unit 151 shown in FIG. 7A until time T6. Note that time T6 is later than time T3. Therefore, at time T6, the contact portion 621 has already been electrically separated from the contact portion 622. Operation diagrams between times T6 and T7 are shown in FIGS. 5F and 6F. By the operation of the operator, the operation unit 151 is returned by the return force of the moving member 41 after the elapse of T6. That is, after the elapse of time T6, the moving member 41 starts moving in the second direction (direction B). The operator does not need to return the operation unit 151. That is, in the case of the present embodiment, the moving member 41 moves from the end point (second position) to the start point (first position) by the adsorption force by the magnetic force of the adsorber 411 and the adsorber 312.

  At time T7, the moving member 41 again contacts the power generation unit 31 and the contact portion 621. That is, the contact portion 621 contacts the contact portion 623. Then, the power generation unit 31, the moving member 41, and the contact unit 62 return to the initial state illustrated in FIG. 5A or 6A at time T7.

  At this time, the switch unit 61 returns to the state of FIG. 7B, and the input terminal 21 is connected to the output terminal 22B. Then, the power stored in the capacitor 71 is supplied to the output terminal 22B.

  As shown in FIG. 4, in the present embodiment, the period from time T1 to time T2 is longer than the period T4. That is, the power generation unit 31 is configured such that the period (time T1 to time T2) generated by the power generation unit 31 is longer than the period T4. From the second time T3 to the time T7, the contact portion 621 remains electrically separated from the contact portion 623. That is, the switch unit 61 is in the state of FIG. 7D. As a result, during the period from time T3 to time T7, the output of power from any of the output terminal 22A and the output terminal 22B is blocked. Therefore, the power generated by the power generation unit 31 in this period is stored in the capacitor 71. Then, at time T7, the contact portion 621 is connected to the contact portion 623 so that the power stored in the capacitor 71 is supplied to the output terminal 22B. At this time, the switch unit 61 is in the state of FIG. 7B.

  As is clear from the above description, since the time T3 shown in FIG. 4 is earlier than the time T2, the power generated by the power generation unit 31 can be output from the output terminal 22A during the period T4. Further, by moving the moving member 41 in the second direction, the power stored in the capacitor 71 can be output from the output terminal 22B. Therefore, the power generated by the power generation unit 31 can be selectively output to the output terminal 22A and the output terminal 22B. Further, even if the time T6 is later than the first time T2, power can be output. That is, even when the operation unit 151 is operated in the second direction after the time when the power generation unit 31 can continue the power generation (first time T2), the power generation device 11 can output the power.

  In addition, although time T2 is before time T5, it does not restrict to this composition. The time T2 may be later than the time T5. Also, time T2 may be later than time T7. In this case, as shown by the characteristic curve S311, the power generation unit 31 generates power between time T6 and time T7. Even in the case of such a configuration of the power generation device, power can be output from the output terminal 22B by the movement of the moving member 41 in the second direction.

  When the moving member 41 returns to the starting point (first position), the moving member 41 is in a state of being adsorbed to the power generation unit 31 (see FIG. 5A). Therefore, when the time T7 is reached, the vibration of the power generation unit 31 is forcibly stopped by the moving member 41 even if the power generation unit 31 generates power. As a result, the power generation in the power generation unit 31 ends.

[First Application Example of Electronic Device 15]
Next, an example in which the electronic device 15 is used as a sensor for detecting the opening and closing of a window will be described with reference to FIG. 7A. The electronic device 15 is attached to a sash portion or the like of the window, and detects the open / closed state of the window itself or a lock. Hereinafter, an example in which the electronic device is attached to the window sash will be described. In this case, the signal processing circuit 153 preferably includes a transmission circuit.

  When the window is closed, the operation unit 151 shown in FIG. 7A is located in the initial state. That is, the moving member 41 is located at the start point (see FIG. 5A). Then, when the window is opened, the operation unit 151 shown in FIG. 7A is pressed by the outer frame of the window. Thereby, the moving member 41 moves from the start point to the end point (see FIG. 5E). During this time, power can be output from the output terminal 22A. Then, the signal processing circuit 153 is activated by the power output from the output terminal 22A. With this configuration, the signal processing circuit 153 can detect that the window is opened by the signal (or power or the like) output from the output terminal 22A. Then, when detecting that the window is opened, the signal processing circuit 153 transmits a signal to a parent device (not shown). The signal processing circuit 153 may be configured to detect a change in the state of the window by detecting the operation detection unit 152 (see FIG. 11). The operation detection unit 152 will be described later.

  After transmitting the signal, the power generation device 11 is set to stop the output of the power (signal) from the output terminal 22A. That is, the switch unit 61 changes the state of FIG. 7B to the state of FIG. 7C. After stopping the output of the power (signal) from the output terminal 22A, the power generated by the power generation unit 31 is stored in the capacitor 71. Then, the power generated by the power generation unit 31 is maintained in the state of being stored in the capacitor 71 until the window is closed again.

  By closing the window from the open state of the window, the operation unit 151 moves in the second direction. The moving member 41 returns from the end point to the start point, and the power stored in the capacitor 71 is output from the output terminal 22B. Thereby, the signal processing circuit 153 can be activated again. With this configuration, the signal processing circuit 153 can detect that the window is closed by the signal (or power) output from the output terminal 22B. Then, when the signal processing circuit 153 detects that the window is closed, the signal processing circuit 153 transmits a signal to the parent device. As described above, the power generated by the power generation unit 31 is stored in the capacitor 71 even if the period from opening the window to closing the window is long. The power generation device 11 can detect the operation of the operation unit 151 even in applications where the time during which the operation unit 151 is operated is long. Then, the master unit can detect the open / close state of the window.

  Then, after the base unit receives the signal indicating that the window has been opened, it is determined that the signal indicating that the window has been closed has not been received even after the specified time has elapsed, a notification unit (not shown) Has output a warning from The specified time determined by the master unit is set shorter than the limit time for which the capacitor 71 can maintain the power. Note that the warning of the parent device may be canceled after a time longer than the limit time for which the capacitor 71 can maintain the power. Therefore, it is preferable that the power generation device 11 be configured to output a signal to cancel the warning from the transmission circuit when the window is opened and closed according to a predetermined rule. In this case, the last operation of the predetermined rule is finished by closing the window. As described above, it is possible to determine that the window is in the closed state (initial state) by receiving the signal indicating the release of the warning in the parent device.

[Second Application Example of Electronic Device 15]
Next, another example of the electronic device 16 will be described with reference to FIGS. FIG. 8 is a top view of the electronic device 16. FIG. 9 is a cross-sectional view of the electronic device 16. FIG. 10 is an exploded perspective view of an essential part of the electronic device 16. FIG. 11 is a circuit block diagram of the electronic device 16. 9 shows a state in which the electronic device 16 of FIG. 8 is cut along the section line 9-9. The electronic device 16 shown in FIG. 8 is a remote control. The electronic device 16 includes an operation detection unit 152 and a transmission unit 156. The operation detection unit 152 detects an operation of the operation unit 151 by the operator, and outputs a detection signal to the signal processing circuit 153. Note that the signal processing circuit 153 has a terminal 1533. Then, the signal processing circuit 153 operates by connecting the terminal 1533 and the output terminal 22. That is, the power generation device 11 outputs power when the operation unit 151 is turned on and when the operation unit 151 is turned off. Therefore, the signal processing circuit 153 can operate when the operation unit 151 is turned on and when it is turned off.

  The electronic device 16 has a plurality of operation units 151. In this case, the operation detection unit 152 is disposed below each operation unit 151. That is, when the operation unit 151 of m columns and n rows is required, the operation detection unit 152 of m columns and n rows is included. Then, the operation detection unit 152 is turned on / off by the operation of the operation unit 151. As the operation detection unit 152, a pair of conductive rubber contacts 1521 and contact conductors 1522 can be used. In this case, the conductive rubber contact 1521 is attached to the lower surface of the operation unit 151. On the other hand, the pair of contact conductors 1522 and the conductive rubber contacts 1521 are disposed at opposing positions. The contact conductor 1522 can be formed of a conductor pattern formed on a printed circuit board. Then, when the operation portion 151 is pushed down, the contact conductor 1522 facing the conductive rubber contact 1521 comes into contact, whereby the pair of contact conductors 1522 and the conductive rubber contact 1521 are conducted. Then, with this configuration, the operation detection unit 152 is turned on. In addition, as the operation detection part 152, you may use not only a rubber contact but a general purpose push switch, for example.

  The signal processing circuit 153 includes m output terminals 1534 and n input terminals 1535. Then, the signal processing circuit 153 outputs a detection signal to the operation detection unit 152 in order from the output terminal 1534. Then, each time a detection signal is output from one output terminal 1534, the signal processing circuit 153 sequentially searches the input terminal 1535 to detect the input of the detection signal. Then, this operation can detect which operation unit 151 has been operated.

  The electronic device 16 may further include a housing 155 (see FIG. 8). The power generation device 11, the operation unit 151, the operation detection unit 152, and the signal processing circuit 153 are housed in a housing 155. Then, a part of the operation unit 151 protrudes from the housing 155. Note that the moving member 41 moves even when any operation unit 151 is operated. For that purpose, the power generation device 11 includes, for example, a slider 157 that moves up and down together with the operation unit 151 and transmits the up and down movement to the moving member 41. The printed circuit board on which the contact conductor 1522 is formed can also constitute a part of the slider 157. With this configuration, even if any operation unit 151 is operated, the operation can be transmitted to the moving member 41. Therefore, the number of power generation devices 11 can be reduced. As a result, the electronic device 16 can be made lighter. Also, the electronic device 16 can be made smaller. When the power generation device 11 is also used as the operation detection unit 152, the same number of power generation devices 11 as the operation units 151 are accommodated. That is, one power generation device 11 is prepared for one operation unit 151.

  The present disclosure is not limited to the above embodiments, and various modifications are possible, which are also included in the scope of the present disclosure.
