Problems solved by technology

However, this method increases the size of the device including the piezoelectric element, so it is not suitable for power generation switch applications
Therefore, as shown in Patent Document 1, it is difficult to put into practical use a mechanism that obtains electric power by freely vibrating a piezoelectric element having a bimorph structure.

Embodiment approach 1

[0094] First, the configuration of the generator switch according to Embodiment 1 of the present invention will be described. figure 1 It is a figure which shows an example of usage of the wireless remote controller 200 provided with the power generation switch concerning Embodiment 1 of this invention. Such as figure 1 As shown, the wireless remote controller 200 includes a button 99 and a power generation switch 100 .

[0095] When the user presses the button 99, the force is transmitted to the power generation switch 100, and the power generation switch 100 generates power.

[0096] The generator switch 100 is a generator switch driven by electric power obtained through an inverse magnetostrictive effect generated by a magnetostrictive element. The internal circuit 98 generates a predetermined wireless signal with the electric power generated by the power generation switch 100 , and wirelessly transmits the generated wireless signal from the transmission unit 97 . In a...

Embodiment approach 2

[0161] In the above, in the first embodiment and its modified example, the power generation switch corresponding to the operation of the user pushing the operation member vertically downward has been described.

[0162] Next, refer to Figure 11A ~ Figure 12C , to describe the power generation switch that responds to the action of the user sliding the operation member in the horizontal direction.

[0163] Figure 11A ~ Figure 11C It is a figure which shows the structure of the power generation switch 100b which concerns on Embodiment 2 of this invention. again, yes and Figure 6A ~ Figure 6C The same constituent elements are assigned the same symbols, and detailed descriptions thereof are omitted.

[0164] refer to Figure 11A The power generation switch 100b includes a power generation element 90b and an operating member 50a.

[0165] The power generating element 90b is a member in which the connecting member 10b included in the power generating element 90 is replaced wi...

Embodiment approach 3

[0175] Next, the configuration of the generator switch that can further increase the rigidity of the parallel beam while suppressing an unavoidable external force applied by the user by the principle of leverage will be described.

[0176] Figure 13A ~ Figure 13C It is a figure which shows the structure of the power generation switch 100d which concerns on Embodiment 3 of this invention.

[0177] Such as Figure 13A As shown, the power generation switch 100d includes a power generation element 90d, a hinge 70, and an operation member 72. As shown in FIG.

[0178] refer to Figure 13B and Figure 13C , the hinge 70 is the fulcrum of the lever, the end of the end of the operation member 72 that is in contact with the power generating element 90d is the action point, and the end of the other end of the operation member 72 to which an external force is applied due to the operation of the user is the force point. Therefore, by making the distance from the fulcrum to the force ...

Abstract

This power generation switch (100) is provided with: parallel beams (11a, 11b) that include at least one magnetostrictive rod that is a magnetostrictive material formed into a beam shape; coils (12a, 12b) wound around the magnetostrictive rod; a first joining member (10a) that, at the first end of the parallel beams, is a member that joins two beams that configure the parallel beams; a second joining member (10b) that, at the second end, is a member that joins the two beams that configure the parallel beams; field magnet units (14a, 14b) that cause the generation of magnetic flux penetrating each of the two beams in the same orientation; and an operation member (50) that a user operates. The first joining member forms an affixed end that is not displaced, and the second joining member forms a free end that can oscillate freely. The operation member applies external force to the second joining member in a manner so that a free oscillation wherein positive axial force arises at one of the two beams and negative axial force arises at the other of the two beams arises at the parallel beams.

Description

technical field [0001] The invention relates to a generator switch, in particular to a generator switch driven by electric power obtained through the reverse magnetostrictive effect generated by a magnetostrictive element. Background technique [0002] In remote controls used for televisions, air conditioners, lighting, etc., there is a demand not to use batteries. The reason is that the dry battery will be consumed and sooner or later the remaining capacity will disappear. In addition, the user is forced to take the trouble to replace the battery. In addition, batteries are industrial waste, so the cost of disposal is also high. [0003] Therefore, the practical use of a "power generation switch" that generates electricity by pressing a button (mechanical operation) and transmits a signal generated by the obtained power to a TV, Air conditioner and lighting switch. If it is implemented, for example, the remote control becomes battery-free. In addition, for example, whe...
