It is a principal part vertical sectional view when a foot applies a load to the front part of the insole.
FIG. 5 is a diagram in which an insole in a foot insole having a power generation function according to the present invention is attached to a shoe, and a power take-out device is connected to the insole. It is sectional drawing.

First, as shown in FIG. 5, the insole insole 32 having a power generation function according to the present invention is laid on the bottom surface inside the shoe and the shoe is put on. At this time, the connecting device 46b shown in FIG. 5 is not attached.
In FIG. 4 (a), the person is standing and standing still. At this time, the load applied to the sole of the foot is the sole at the position corresponding to the joint composed of the metatarsal bone (not shown) and the base bone (not shown) in the human foot. That is, a load of W / 2 (kg) is equally applied to the front sole portion 49 and the sole portion of the heel in the human foot, that is, the rear sole portion 50. At this time, since the upper portion 36 of the insole 32 is not deformed, the hydraulic fluid 41 does not move and flow, and the impeller 39 does not rotate. Therefore, the generator 40 does not generate generator power. Further, since no deformation occurs in the front power generation seat 37d and the rear power generation seat 37e, the power generation seat power does not generate generator power.

Next, as shown in FIG. 4B, when a person steps his / her foot forward and lands on the ground from the heel, a load W (kg) is applied to the rear sole 50. The rear working fluid storage part 37b is pressed by the rear foot part 50 and is compressed and deformed. Therefore, as shown in FIG. 4B, the hydraulic fluid 41 stored in the rear hydraulic fluid storage portion 37b moves vigorously in the direction indicated by the arrow and moves to the front hydraulic fluid storage portion 37a. To do. Then, as shown in FIG. 4 (b), the impeller 39 rotates in the R1 direction by the working fluid 41 flowing through, and the generator 40 generates generator power. In addition, the rear power generation sheet 37e attached to the rear working fluid container 37b that has been compressed and deformed at the same time is generated by a piezo film having a power generation function made of polyvinylidene fluoride (PVDF) or the like based on the piezoelectric effect theory. Furthermore, since the front working fluid container 37a is expanded and deformed by the working fluid 41 moved to the front working fluid container 37a, the front power generation sheet 37d attached to the front working fluid container 37a is made of polyvinylidene fluoride (PVDF) or the like. A piezo film having a power generation function is configured to generate power generation sheet power according to the piezo effect theory.

The generator power obtained from the generator 40 and the power generation seat power obtained from the front power generation seat 37d and the rear power generation seat 37e are charged to the rechargeable battery 44 via the control circuit unit 42, respectively.

Next, as shown in FIG. 4C, when a person kicks the foot backward, a load W (kg) is applied to the front foot sole 49. The front hydraulic fluid storage portion 37a is pressed by the front sole portion 49 and is compressed and deformed. Therefore, as shown in FIG. 4C, the hydraulic fluid 41 stored in the front hydraulic fluid storage portion 37a vigorously flows through the hydraulic fluid flow portion 37c in the direction indicated by the arrow and moves to the rear hydraulic fluid storage portion 37b. To do. Then, as shown in FIG. 4 (c), the impeller 39 rotates in the R2 direction by the working fluid 41 flowing through, and the generator 40 generates generator power. At the same time, the front power generation sheet 37d adhered to the front working fluid container 37a that has been compressed and deformed is a piezoelectric film having a power generation function made of polyvinylidene fluoride (PVDF) or the like to generate power generation sheet power based on the piezoelectric effect theory. Furthermore, since the hydraulic fluid 41 moved to the hydraulic fluid reservoir 37b expands and deforms the hydraulic fluid reservoir 37b, the rear power generation sheet 37e adhered to the hydraulic fluid reservoir 37b is polyvinylidene fluoride (PVDF) or the like. A piezo film having a power generation function is configured to generate power generation sheet power according to the piezo effect theory.

The generator power obtained from the generator 40 and the power generation seat power obtained from the front power generation seat 37d and the rear power generation seat 37e are charged to the rechargeable battery 44 via the control circuit unit 42, respectively. As described above, the insole 32 of the footwear insole having the power generation function according to the present invention includes the generator power and the power generation obtained by moving and flowing the hydraulic fluid 41 through the hydraulic fluid storage portion 37 with walking. The seat power can be continuously charged.

Next, the handling after the insole of the insole having the power generation function according to the present invention is charged after walking will be described in detail with reference to FIG.
The contact portion cover 48 located at the rear end of the rear portion 34 of the insole 32 is opened as shown in FIG. 5 to connect the connection device 46 b to the external connection portion 45. At this time, as shown in FIGS. 3B and 3C, the two magnets 46b2 and 46b2 of the connection device 46b are attracted to the two ferromagnetic parts 45b and 45b of the external connection part 45 by their magnetic force. As a result, the mutual positions of the connection device 46b and the external connection portion 45 are determined. When the connection device 46b is fixed to the external connection portion 45, the contact pins 46b3 and 46b3 and the contact 46b5 that are installed on the connection device 46b and locked at a position protruding, for example, 1 (mm) from the lower end surface of the connection device 46b. , 46b5 are pressed against the contact portions 45a, 45a disposed in the external connection portion 45, and the insole 32 and the power take-out device 46 are electrically connected.

When the insole 32 is electrically connected to the power take-out device 46, the power stored in the rechargeable battery 44 of the insole 32 is converted into a general-purpose rechargeable battery 46a2 by the operation of the power conversion unit 46a1 and the charge control unit 46a3 of the control circuit unit 46a. , 46a2 is converted into electric power for the general purpose rechargeable batteries 46a2, 46a2. The charged general-purpose rechargeable batteries 46a2 and 46a2 can be taken out from the power take-out device 46 and used as a power source for portable music players, digital cameras, and the like.

The present invention can be used as a power source for portable music players, digital cameras, etc. by charging the general-purpose rechargeable battery attached to the power take-out device on the go with the power charged by the insole laid on the shoes worn when going out can do.
