Abstract

PURPOSE: To facilitate free selection of the location to some extent by a method wherein the kinetic energy of a displacement member which is moved reciprocally when a heavy object passes over a displacement mechanism is converted into the electric energy and outputted. CONSTITUTION: When a vehicle, a human body, etc., passes over a displacement mechanism 100 and a load is applied to an upper plate 110, the upper plate 110 which is at a reference position is made to sink to a lower limit position. When the vehicle, the human body, etc., leaves the displacement mechanism 100, the upper plate 110 is restored to the reference position by the actuation force of a spring part 150. By the reciprocal movement of the upper plate 110, a current is generated in a coil 141 and a battery 200 is charged. The accumulated electric energy is taken out from the terminals of the battery 200 and used as an auxiliary power supply. Therefore, by setting the location region of the mechanism relatively widely, the necessary and sufficient electric energy can be obtained.

It is composed of a rectifying circuit 160 for outputting to 00.

The coil portion 140 is composed of a coil 141 having a plurality of turns and a cylindrical bobbin 142 having the coil 141 wound around the outer peripheral surface thereof.
2 is configured as a cylindrical member having a cavity 142a into which the magnet 131 is inserted. The coils 141 of the coil section 140 are connected to the rectifier circuit 160, respectively.

The spring portion 150 is formed as a columnar body having a spring 151 and a protrusion 152a as a stopper at the lower end thereof, and the upper end thereof is joined to the upper plate 110 inside the spring 151. Stop member 1
52, a hollow portion inside thereof, a guide groove 153a on the side surface thereof, and a lower engaging member 153 whose lower end portion is joined to the lower plate 120. The upper locking member 152 and the lower locking member 153 are attached so that the projection 152a of the upper locking member 152 is inserted into the guide groove 153a of the lower locking member 153. The spring portions 150 are arranged for every predetermined unit number of the coil portions 140 over the entire area of the plate.

In the displacement mechanism 100 having such a structure, the upper plate 110 is biased upward by the spring 151. When no load is applied to the upper plate 100, as shown in FIG. 2, in the upper plate 110, the projection 152a of the upper locking member 152 has the upper end portion of the guide groove 153a of the lower locking member 153. It is positioned at the position (reference position) where it abuts against.

On the other hand, when a load is applied to the upper plate 110, the upper plate 110 sinks against the biasing force of the spring 151 according to the magnitude of the applied load. When this load increases, the lower end (protrusion 152a) of the upper locking member 152 contacts the lower plate 120, as shown in FIG. Then, the movement of the upper plate 110 is stopped at the position (lower limit position) where the upper locking member 152 and the lower plate are in contact with each other. Upper plate 11
When 0 is at this lower limit position, N of the bar-shaped magnet 131 is
The pole is in a state of being inserted into the cavity 142a of the bobbin 142. Further, when the load is released from the state where the upper plate 110 is at the lower limit position and no load is applied, the upper plate 150 moves upward due to the urging force of the spring 151 of the spring portion 150 and returns to the reference position again.

Located at a relatively far distance defined by ₁ ,
At the lower limit position, the bar-shaped magnet 131 and the coil portion 140
Are positioned at close distances defined by the separation distance h ₂ .

Therefore, by repeatedly applying and releasing a load to the upper plate 110, the upper plate 110 reciprocates in the direction of approaching and separating from the lower plate 120. The reciprocating movement of the upper plate 110 in the vertical direction causes the magnet 131 penetrating the coil 141.
The magnetic flux from the coil changes, and due to this change in the magnetic flux, the coil 14
A current flows through 1.

At this time, the current flowing through the coil 141 is
It is defined by the induced electromotive force generated by changes in the coil and magnetic flux. And this induced electromotive force can be defined by the following formula (1).

E = −n (∂φ / ∂t) (1) In the above equation, e: induced electromotive force n: number of turns of coil φ: magnetic flux t: time

Then, the current of the coil 141 is supplied to the rectifier circuit 16
After rectifying at 0, it is supplied to the battery 200. The battery 200 is charged by the supplied current and stores electric energy.

When power is actually generated by the embodiment configured as described above, the displacement mechanism 100 is first laid on a road or the like. At this time, if the displacement mechanism 100 is configured as a rectangular block and a plurality of blocks are appropriately arranged, the laying work can be facilitated and the blocks can be laid in various shaped regions, which is convenient. Then, the battery 200 is arbitrarily installed near the place where the displacement mechanism 100 is laid.

When a vehicle, a person, or the like passes over the displacement mechanism 100, a human foot, a vehicle wheel, or the like is placed on the upper plate 110 and the upper plate 100.
When a load is applied to the upper plate 110, the upper plate 110, which was in the reference position shown in FIG. 2 until then, sinks to the lower limit position shown in FIG. When these human feet or the wheels of the vehicle are separated from the upper plate 110, the upper plate 110 returns to the reference position by the urging force of the spring portion 150.

When the upper plate 110 reciprocates, a current flows through the coil 141 and the battery 200 is charged by the above-described operation. The charged electric energy is taken out from the terminal terminal of the battery 200 and used as an auxiliary power source in the peripheral portion thereof. The auxiliary power source will be described later.

Therefore, it is possible to acquire necessary and sufficient electric energy by setting the place where the displacement mechanism 100 is installed to a place where the traffic volume is heavy and setting the installation area to a certain extent. In particular, highways and highways are suitable as places to which this embodiment is applied.

Next, another embodiment according to the present invention will be described with reference to the drawings. FIG. 4 is a view showing another embodiment of the power generator according to the present invention, and is a view showing the configuration of the displacement mechanism 100. In the figure, 130 is the upper plate 110.
A plurality of flat plate-shaped magnets 132 that are bonded to the lower surface of the
Are magnet layers arranged in a square lattice, and 170 is a coil portion 1.
The foamed elastic body is disposed between the upper surface of 40 and the lower surface of the coil portion 130. In the figure, the same parts as those of the embodiment described above are designated by the same reference numerals. The configuration other than that shown in the figure is the same as that of the above-described embodiment, and the description thereof is omitted.

As the magnet 132 of the magnet layer 130,
A magnet as shown in FIG. 5 (a) is used. That is,
The magnet 132 is configured as a thin cylindrical ferromagnetic material, and has an upper surface 132a magnetized with an S pole and a lower surface 132b magnetized with an N pole.

In the coil section 140, a coil 143 shown in FIG. 5B is printed on a magnetically permeable printed circuit board. The coil 143 is formed in a spiral shape, and a section 143b extending from the central portion to the outer contact portion 143a is formed in another layer. And contact point 143

It is connected to 60.

The foamed elastic body 170 is the upper plate 11
It acts as a biasing means for biasing 0 upward. A well-known foaming material is used for the foamed elastic body 170, and this foaming material has magnetic permeability. In this embodiment, a material having a good compression / restoration property, that is, when the load is applied and the load is removed, the material is immediately restored to its original state and has durability against this load. The material is suitable.

Then, the relative distance between the magnet 132 and the coil 143 is determined by the upper plate 11 as shown in FIG. 5 (c).
The distance h ₃ and the upper plate 11 when 0 is at the reference position
It changes during the distance h4 when 0 is in the depressed position. Then, according to this change, the magnetic flux B from the magnet 132 penetrating the coil 143 changes. In this configuration,
As described above, since both the magnet 132 and the coil 143 are made thin, there is a feature that sufficient power generation can be obtained even if the device is made thin.

The upper plate 1 in this embodiment

For example, a side surface of the upper plate 110 and the lower plate 120 is joined with a stretchable side surface member such as a bellows plate to hermetically seal the space formed between them to form a hermetically sealed structure. Then, urging means such as the spring portion 150 is arranged inside the sealed structure, a liquid medium such as water is filled, and inflow holes and discharge holes are formed at appropriate positions of the sealed structure. . Further, a backflow prevention valve is attached to each of these holes so that a flow path of the liquid medium is formed in the order of the inflow hole, the internal space, and the protruding hole.

With this structure, when a load is applied to the upper plate 110 and the upper plate 110 sinks, the liquid medium in the internal space is discharged to the outside through the discharge holes. Further, when the load on the upper plate 110 is released and biased upward, the liquid medium existing outside flows into the internal space of the sealed structure through the inflow hole.

Then, the rotor is rotated by the liquid medium discharged from the discharge holes, thereby generating electricity. The mechanism that obtains electrical energy from the rotation of the rotor at this time is
For example, a known power generation mechanism such as a bicycle power generator can be used.

Further, in a similar mechanism, the medium for filling the internal space may be air, and the wind turbine may be rotated by the air discharged from the discharge holes.

In the two embodiments described above, the electric energy stored in the battery 200 is

This auxiliary power supply is the power supply for the traffic lights, the power supply for street lights,
It can be more suitably used as a power source for road surface freeze prevention or snow melting in cold regions.
