Description

The present invention relates to a display device in which a light emitting diode is turned on to notify the location thereof by the electric energy of a vibration power generation apparatus in which a magnet moves in a coil by the movement of a pendulum and generates an induced current in the coil.

  When taking a walk at night, there are methods to inform the outside of the person, such as holding an electric light, attaching a battery-powered display to the body, or attaching a reflector to the body, or a magnet in the coil There are some which use electric power of a vibration power generation device that generates electricity by moving the light bulb, and light bulbs are lit.

One is to insert a magnet into the pipe of the power generation unit, provide a coil outside the pipe, and use the magnet's own weight to place the magnet below the coil. The magnet of the moving part having a polarity that gives a repulsive force is brought close to the magnet of the power generation part so that it passes through the coil to obtain electrical energy.
Furthermore, the magnet of the moving part moves and moves away, and the repulsive magnetic force of both magnets is weakened, so that the magnet of the power generating part passes through the coil and returns to its original position. (Reference 1)

In addition, there is a type in which a spring is connected to the lower part of the magnet of the vibration power generator and a coil is provided on the outside of the pipe, and the entire magnet is vibrated so that the magnet moves in the coil to generate power. (Reference 3)
Alternatively, instead of a spring, a magnet having a polarity that gives a repulsive force to the magnet is arranged in the lower part of the pipe, and similarly, there is a thing in which the generated power is obtained by applying vibration to the whole. (Reference 2)
In addition, there are things that shake the vibration power generator as it is, move the internal magnet to light the light bulb, and things that attach the vibration power generator to clothes and light the light bulb.

Japanese Patent Application Laid-Open No. 60-13464 JP 2010-200479 A JP 2002-374661 A

As proposed in Patent Document 1, the magnet of the power generation unit is moved using the magnet of the moving unit to generate power, and the return uses the self-weight of the magnet of the power generation unit. Is inclined, it may not return to the original position, and the structure for attaching the magnet of the moving part to the human body may be complicated.

In Documents 2 and 3, since vibration is applied to the magnet in the pipe and the amount of power generated in the coil is determined by the size and moving speed of the magnet, quick vibration is required.
Therefore, when it is used to stop repeated vibrations and generate electricity by gradually tilting the device and moving the magnet, the magnet in the pipe starts to move according to the tilt. When the light emitting diode is turned on with the electric energy, the power is generated, but the illuminance decreases.

A display device in which a light-emitting diode is lit by electrical energy using the vibration power generation device of the present invention is mainly used when the display device is attached to a human body and a person moves, and the inertial force of the pendulum inside the display device when stopped. The light-emitting diode is turned on to connect an elastic tension spring to a first magnet that generates an induced current in the first coil, and a flexible spring is connected to the other end of the tension spring. Connect the wires and place them in the pipe.
The end of the wire is connected to the lower part of the pendulum where the cylindrical bar serves as a fulcrum, and the first coil is provided on the outer periphery of the pipe, and the cylindrical bar and the first coil are fixed to the case.

A screw-like magnetic body that applies an attractive force to the first magnet is inserted into a nut having a screw shape inside and a non-magnetic body, and the magnetic body is moved so that the first magnet attracts and approaches.
By the movement of the magnetic body, the distance between the magnetic body and the first magnet changes, and the attractive force due to the magnetic force can be adjusted.
Thereby, the first magnet and the magnetic body are in a state of being attracted and approached in a normal state.

A band is attached to the back of the case, and the indicator of this proposal is attached to the human limb by this band.
When the person is standing vertically and the case is attached to the foot horizontally, when the person walks and stops, the upper part of the pendulum moves in the direction of inertia with the upper part of the pendulum as the fulcrum, pulling the wire, and the tension spring Will grow.

At the moment when the inertial force generated by the inertia of the first magnet and the pendulum generated when stopped exceeds the attractive force of the first magnet and the magnetic body and the expansion and contraction force of the tension spring, the first magnet moves in the inertial direction. Passes through one coil.
At this time, an induced current is generated in the first coil, and the terminal light emitting diode is turned on by the output.

In addition, the first magnet connected to the tension spring moves in the pendulum movement direction, the tension spring contracts, and the flexible wire is loosened. The first magnet moves in the form of acceleration in the direction of movement of the pendulum.
As a result, the moving speed of the first magnet moves in the first coil faster than the moving speed of the normal case, and the induced current generated in the first coil increases due to the instantaneous movement, thereby generating high electrical energy. To do.

Thereafter, the moved first magnet moves to the distance generated by the loosening of the wire in addition to the movement distance of the pendulum, and the connection plate attached to the first magnet collides with the pendulum.
Further, the connection plate that has collided with the pendulum repels and moves in the direction in which the magnetic body is present due to the inertial reaction, and then the end of the connection plate attached to the first magnet is moved by the pendulum gravity to the pendulum. Will push.
On the other hand, the magnetic force obtained from the magnetic body is also applied, and the first magnet again passes through the first coil and moves to the original position, and the magnetic body and the first magnet are attracted and approached.

When light emitting diodes are turned on by applying a normal vibration power generation device and the location is informed to the surroundings, when the vibration power generation device is gradually inclined, the first magnet inside the pipe starts to move according to the angle. Therefore, the moving speed in the first coil becomes slow, and the light emitting diode cannot be lit brightly.
Further, as in Document 1, it is difficult to provide the magnet of the moving unit at another part of the human body because the apparatus becomes complicated.

However, in this proposal, the inertial force repeatedly generated when a person stops is used to give a large pulling force to the tension spring when a certain inertial force is applied to the pendulum regardless of the tilt of the case. .
After that, the wire continues to be pulled, and the moment the inertial force exceeds the contraction force of the tension spring and the attractive force of the first magnet and the magnetic material, the first magnet in the pipe moves in the first coil faster than the walking speed. Thus, it is possible to turn on the light emitting diode by generating instantaneous electrical energy.

The first magnet can use the space due to the loosening of the wire even at the destination in the pipe. If several coils including new second and third coils are arranged within the range, the first magnet can be obtained by the first coil. It is possible to acquire electrical energy at a destination that has not existed, generate electrical energy in a plurality of coils attached to the outer periphery of the pipe, and extract larger electric power.

Hereinafter, preferred embodiments of the display 1 according to the present invention will be described with reference to the drawings.
FIG. 1 is a view in which the display 1 of the present invention is attached to a hand or foot of a human body, FIG. 2 is a perspective view showing the details, and FIG. 3 is a first coil 5 and a pipe 6 and a first magnet 3. It is the figure which represented the part etc. in the cross section.

As shown in FIGS. 1 and 2, in order to attach the display 1 to a human hand or foot, as shown in FIGS. Sometimes, as shown in FIG. 1, a band 23 is wound around the hand or ankle, and the male surface fastener 11 and the female surface fastener 14 at the tip are connected and fixed.

As shown in the perspective view of FIG. 2 and the cross-sectional view of FIG. 3, the internal structure of the display 1 is attached to the left end of the first magnet 3 by attaching a cushion 8 to one side of the first magnet 3 inside the pipe 6. The plate 24 and the elastic tension spring 4 are connected, and the flexible wire 13 is connected to the other end of the tension spring 4.

  There is a first coil 5 on the outer periphery of the pipe 6, and the induced current generated from the first coil 5 is output to the first light emitting diode 2 and the second light emitting diode 25 attached to the side surface of the case 10 by the electric wire 12, The contents of the electric wiring are shown in FIG.

  A cushion 16 is attached to the case 10, and a cushion 8 is attached to the first magnet 3. These move the pendulum 17 and the first magnet 3 to hit the case 10, and generate a collision sound and impact generated at that time. It is for absorption, and it is not necessary to use it if there is no trouble in operation.

In FIG. 3, the tension spring 4 can be easily expanded and contracted in the connection plate 24, the other of the tension spring 4 is connected to the wire 13, and the other of the wire 13 is attached to the lower part of the pendulum 17.
The upper part of the pendulum 17 has a hole, and a cylindrical bar 15 is inserted into the hole. The cylindrical bar 15 is fixed to the case 10, and the pendulum 17 has the lower part of the pendulum 17 as a fulcrum. It is designed to be able to rotate and move in a semicircle.

As a result, as shown in FIG. 3, when the case 10 is in a horizontal state, the lower part of the pendulum 17 is in the vicinity of just below the cylindrical rod 15 due to gravity.
Further, a weight 18 is attached to the pendulum 17 so as to apply a force to the pendulum 17 by a half-rotation, and the pulling force of the wire 13 can be changed by the weight of the weight 18.
Therefore, the weight 18 may be omitted when the wire 13 can be sufficiently pulled only by the pendulum 17.

  A non-magnetic nut 7 having a screw hole is fixed to the right side surface of the case 10, and a screw-like magnetic body 9 that can move in the nut 7 is attached. If it is horizontal and in a normal state, it moves to the right side by the magnetic force of the first magnet 3, attracts the magnetic body 9, and stops.

As shown in FIGS. 2 and 4, a band 23 is attached to the back surface of the case 10, a male surface fastener 11 and a female surface fastener 14 are attached to each end, and these surface fasteners are joined together, A case 10 is attached to a person's limb.
Further, in order to change the inclination of the case 10 and maintain the state, the band 23 and the case 10 are connected using the screw 19 and the compression spring 20.
As a result, as shown in FIG. 4A, the case 10 and the band 23 are brought into close contact with each other by the compression spring 20, the angle of the case 10 changes, and the angle is further maintained.

  In FIG. 4 (A), the band 23, the screw 19 and the compression spring 20 are attached to the human body while changing the angle of the case 10, but the male surface fastener 21 is attached to the band 23 as shown in FIG. 4 (B). A female surface fastener 22 may be attached to the case 10 so that the case 10 can be easily separated, and the angle of the case 10 can be changed and maintained.

When the case 10 is horizontally attached to a person's right ankle with a band 23 and the person is stopped and in a vertical state as shown in the right leg of FIG. 1, the first magnet 3 attracts the magnetic body 9 to each other. As shown in FIG. 3, it is located on the right side surface of the case 10.
Subsequently, when the right foot starts to move and stops, the pendulum 17 moves as shown in FIG. 5 by the inertial force due to its inertia, pulls the wire 13, and the tension spring 4 in the connection plate 24 extends.

  At this time, when the inertial force of the pendulum 17, the weight 18 and the first magnet 3 generated when the right foot moves and stops exceeds the contraction force of the tension spring 4 and the attractive force of the first magnet 3 and the magnetic body 9. The first magnet 3 moves in the first coil 5 faster than the speed at which the person moves due to the contraction force of the tension spring 4, and moves to a position where the connection plate 24 contacts the pendulum 17 as shown in FIG. To do.

As a result, forward and reverse induced currents are generated in the first coil 5, the first light emitting diode 2 in the front and the second light emitting diode 25 in the rear having different polarities are lit, and the presence of a person is detected in the front and rear. I can inform you.
In addition, when the walking speed is fast, the inertial force applied to the pendulum 17, the weight 18 and the first magnet 3 also increases, and the pulling force of the tension spring 4 increases, greatly increasing the attractive force of the first magnet 3 and the magnetic body 9. And the separation is easily performed, the speed at which the first magnet 3 moves in the first coil 5 is increased, and higher power can be obtained.

The inertial force that the pendulum 17 moves varies depending on the weight and attachment position of the weight 18 attached thereto, the fulcrum position of the pendulum 17, the attachment position of the wire 13, and the like, while the first magnet 3 and the magnetic body 9 are attracted. The force also varies depending on the magnitude of the magnetic force of the first magnet 3 and the interval between the magnetic bodies 9.
Thereby, the magnetic body 9 in the nut 7 is moved so that optimal power generation can be performed, and adjustment is performed so that the first magnet 3 can be moved smoothly.

After the right foot stops and the connection plate 24 moves, the pendulum 17 and the weight 18 that have moved to the left side surface of the case 10 try to return to their original positions due to the reaction and gravity, as shown in FIG. A force acts to push 24 to the right, and the first magnet 3 moves in the first coil 5.
The first magnet 3 also acts as an attractive force due to the magnetic force with the magnetic body 9, moves to the original position, attracts the magnetic body 9 and stops.
As a result, the same operation is repeatedly generated while a person is walking.

Next, a method for generating power without using the tension spring 4 will be described with reference to the drawings.
Since other parts and contents are the same as those in the first embodiment, description thereof is omitted.
Normally, when a person walks with the display 1 attached and the right foot stops, the amount of power generated by only the inertial force is small. Therefore, in the first embodiment, in the first coil 5 using the expansion / contraction force of the tension spring 4. If the display 1 is used at a high speed, the wire 13 is connected to the first magnet 3 as shown in FIG. 8 without using the tension spring 4 shown in FIG. Also good.

In FIG. 8, the magnetic body 9 is moved to weaken the attractive force between the first magnet 3 and the magnetic body 9, the display 1 is attached to the right foot, and further moved at a high speed to stop, the pendulum 17 Since the inertia force of the first magnet 3 increases, the first magnet 3 and the magnetic body 9 can be easily separated from each other, and the first magnet 3 can be connected to the first coil without using the contraction force of the tension spring 4. It is possible to pass through 5 at a high speed.
As a result, the first magnet 3 moves to the left in the first coil 5 at a stretch to generate forward and reverse induced currents in the first coil 5 to light the first light emitting diode 2 and the second light emitting diode 25. be able to.

Next, a method for obtaining high power without using the tension spring 4 and the connection plate 24 by using the display 1 mainly at a high speed such as jogging will be described with reference to the drawings.
Since other parts and contents are the same as those in the first and second embodiments, description thereof is omitted.
9 shortens the lateral width of the case 10 and the pipe 6 of FIG. 3, shortens the distance to the left after the first magnet 3 moves in the first coil 5, and connects the tension spring 4 and the connection plate 24 to each other. It's omitted.

  In FIG. 9, when the display 1 is attached to the right foot and moved at a high speed such as jogging and stopped, the first magnet 3 hits the pendulum 17, and the reaction after the collision is greater than when walking, and the pendulum 17, even if the first magnet 3 is pushed directly to the right, the first magnet 3 can easily return to the right side of the case 10, and the tension spring 4 and the connection plate 24 can be omitted.

  When jogging, the period of the pendulum 17 that swings to the left and right becomes faster, the speed at which the pendulum 17 moves to the left increases, the brightness of the two light-emitting diodes increases, and the reaction after the pendulum 17 and the weight 18 move. Since the generated force is also increased, the speed of the first magnet 3 moving to the right side is increased, and an induced current is generated again in the first coil 5 so that the two light emitting diodes can be turned on.

  In the first to third embodiments, the attraction force due to the magnetic force between the first magnet 3 and the magnetic body 9 is adjusted by the movement of the magnetic body 9, but when the display 1 is always used in the same state, the first If the sizes of the magnet 3, the tension spring 4, the pendulum 17 and the like are constant, the attractive force by the magnetic force is also constant, so that the position and size of the magnetic body 9 can be set to almost the same value. Instead of the magnetic body 9, only a certain size of magnetic body may be attached to the case 10, and the attractive force with the first magnet 3 may be fixed and separated.

The shape of the first magnet 3, the first coil 5, and the pipe 6 may be triangular or polygonal, and the materials for the case 10, the tension spring 4, the pipe 6, etc. other than the first magnet 3 and the magnetic body 9 are as much as possible. A non-magnetic material such as aluminum, stainless steel, plastic, glass, or rubber that does not affect the first magnet 3 or the magnetic material 9 is used.
Furthermore, instead of the elastic tension spring 4, an elastic rubber or cushion may be used.

In Examples 1 to 3, since the flexible wire 13 is used for the connection of the tension spring 4, the first magnet 3 can move to a region where the wire 13 is loosened. If a new coil is installed, the amount of power generation can be increased.

The two light emitting diodes are attached to the side surface of the case 10, but an outlet is provided in the case 10, the output from the first coil 5 is output to the outlet, the plug is connected to the outlet, the electric wire is connected, and the terminal is connected. A clip having a light emitting diode may be attached to the trousers or the waist, and light may be emitted at a place different from the case 10.
Alternatively, instead of the clip, a magnet may be attached to the light emitting diode, a magnetic material may be inserted inside the trouser, the magnet and the magnetic material may be attracted, and the light emitting diode may be fixed to the trouser to emit light.
