Alternatively, an artificial muscle using ICPF may be provided as a mechanical electrical conversion element.

The power generation module 30 further includes a pressure receiving unit 32. The pressure receiving unit 32 transmits the received force to the piezoelectric element.

The mechanical electric converter 100 may further include a metal plate 26 at a position facing the pedestal 90 on the surface 23 on the lower plate 10 side of the upper plate 20. The metal plate 26 prevents the surface 23 of the upper plate 20 from being worn due to contact with the pedestal 90.

The mechanical electrical converter 100 may further include a stopper 50. The stopper 50 defines a limit position in the direction in which the other side 10b of the lower plate 10 and the other side 20b of the upper plate 20 are separated from each other. The stopper 50 has a pin support portion 52 and a pin 54. The pin support portion 52 may be arranged at both corners on the other side 10b side of the upper plate 20. The pin 54 may be fixed to the fixing hole 16 formed at a position facing the pin 54 on the surface 13 of the upper plate 20 through the through hole of the pin support portion 52. The pin 54 has a flange portion at the other end opposite to one end fixed to the fixing hole 16. The pin support portion 52 slidably supports the pin 54 so that it can move together with the upper plate 20. The diameter of the flange portion of the pin 54 is larger than the diameter of the through hole of the pin support portion 52. Therefore, by contacting the flange portion with the peripheral edge portion of the through hole of the pin support portion 52, the movement of the other side 10b of the lower plate 10 and the other side 20b of the upper plate 20 in the direction away from each other is restricted.

According to the mechanical electric conversion device 100 configured in this way, the lower plate 10 and the upper plate 20 are connected via the hinge portion 60 so as to be movable in the approaching direction and the moving direction. As a result, when the lower plate 10 and the upper plate 20 move in the approaching direction or the moving direction away from each other, it is possible to prevent the lower plate 10 and the upper plate 20 from shifting in the direction parallel to the hinge shaft 62 of the hinge portion 60. .. Therefore, the force on the power generation module 30 arranged between the lower plate 10 and the upper plate 20 can be reliably changed. As a result, when the lower plate 10 and the upper plate 20 move in the approaching direction or the moving direction away from each other, the power generation module 30 can surely generate electric power.

The electric power or current that can be generated by one power generation module 30 may not be enough to secure the electric power or current required to drive the wireless module 40. In such a case, a plurality of power generation modules 30 may be required in order to secure the electric power or current required to drive the wireless module 40. Then, in order to drive the wireless module 40, it is desirable that a plurality of power generation modules 30 generate electric power at the same time. However, due to the different positions at which the upper plate 20 is pressed, for example, there is a possibility that each of the plurality of protrusions 24 provided on the back side of the upper plate 20 cannot press each of the plurality of power generation modules 30 at almost the same time. be. A large number of power generation modules 30 are arranged on the lower plate 10 to drive the wireless module 40 in order to reliably secure electric power capable of driving the wireless module 40 even if the upper plate 20 is pressed at a different position. It is also conceivable to secure the power to do so. However, if a large number of power generation modules 30 are arranged, the manufacturing cost, weight, and the like increase. In order to reduce the manufacturing cost and weight, it is preferable to arrange the minimum number of power generation modules 30 that can secure the electric power required to drive the wireless module 40. In this case, the wireless module 40 cannot be driven unless the power generation modules 30 generate electric power substantially at the same time.

According to the mechanical electric converter 100 configured as described above, the lower plate 10 and the upper plate 20 are connected via a hinge portion 60. As a result, when the lower plate 10 and the upper plate 20 move in the approaching direction or the moving direction away from each other, even if the positions of the forces applied to the upper plate 20 are different, the lower plate 10 and the upper plate 20 are connected to the hinge shaft 62. It is possible to suppress the deviation in the direction parallel to.

Further, a plurality of power generation modules 30 are arranged along a direction parallel to the direction of the hinge shaft 62. As a result, when the lower plate 10 and the upper plate 20 move in the approaching direction or the moving direction away from each other, it is possible to prevent variations in the change in the force applied to each of the plurality of power generation modules 30. For example, as shown in FIG. 5, even when the upper plate 20 is pressed at a different position (arrow 201, arrow 202, or arrow 203), the force applied to each of the plurality of power generation modules 30 does not vary. That is, even if the other side 10b side, the side side 10c side, or the side side 10d side of the upper plate 20 is pressed, the force applied to each of the plurality of power generation modules 30 does not vary. The plurality of power generation modules 30 are arranged in parallel with the hinge shaft 62. Therefore, even if the upper plate 20 moves in a direction approaching the lower plate 10 while tilting with respect to the lower plate 10, each of the plurality of power generation modules 30 is pressed by each of the plurality of protrusions 24 of the upper plate 20. The timing is the same. As a result, the plurality of power generation modules 30 can generate electric power substantially at the same time. Therefore, the wireless module 40 can be reliably driven.

As described above, according to the mechanical / electrical conversion device 100, even if an arbitrary position of the upper plate 20 is pressed, the plurality of power generation modules 30 can generate electric power substantially at the same time. The term “simultaneous” is a concept that includes not only the case where the power generation modules 30 are completely simultaneous, but also the case where the timing at which each of the plurality of power generation modules 30 generates electric power is shifted to the extent that the wireless module 40 can be driven.

For example, when the user sits on the upper plate 20 and the power generation module 30a and the power generation module 30b generate power, the current from the output terminal 33a of the power generation module 30a and the output terminal 33b of the power generation module 30b is input to the Vcc port of the wireless module 40. Will be done. Further, the current from the output terminal 33a of the power generation module 30a and the output terminal 33b of the power generation module 30b is input to the first input port 413 of the wireless module 40.

On the other hand, when the user sitting on the upper plate 20 stands and the power generation module 30a and the power generation module 30b generate power, the current from the output terminal 35a of the power generation module 30a and the output terminal 35b of the power generation module 30b is applied to the wireless module 40.
