Description

  The present invention relates to a power storage device, and more particularly to a device that can be charged without receiving power supply from a commercial power source.

  An electric device that is carried while carrying is equipped with a battery (capacitor), and the battery is charged with electric power from a commercial power source by connecting a charger to store the battery. Such an electric device becomes unusable when the stored electric power in the battery is lost while being carried, and therefore it is necessary to carry a spare battery in order to prepare for the case.

  However, the spare battery is in the way and when the stored power is consumed, the electric device can no longer be used. For example, this electric device is very inconvenient in the case of a flashlight used in an emergency, etc. Also, in the case of a mobile phone device, it becomes impossible to call for help if it becomes unavailable during a distress. End up.

For this reason, a power storage device equipped with a rechargeable battery has been devised. For example, a permanent magnet is slidably placed in a dry cell-shaped body, and a conductive wire is wound around the slide portion of the permanent magnet. Thus, it has been proposed to store an electromagnetically induced electromotive force generated by a reciprocating motion of a permanent magnet in the coil in a capacitor (see, for example, Patent Document 1).
Utility model registration No. 3026391

  However, in the power storage device described in Document 1, since the permanent magnet has a structure that is knocked to one end side in the moving space, an abnormal noise that collides with the end portion is generated or the end portion is generated. There is a risk that the main body of the apparatus or the permanent magnet may be damaged by an impact when it is knocked down.

  Further, the power storage device described in Document 1 is configured in an assembly structure in which a coil is formed in the central portion in the thrust direction of a space in which a permanent magnet can move, and capacitors are arranged on both ends thereof. It is difficult to replace the component parts, and if any component fails, the entire component is replaced, and the replacement cost becomes expensive.

  In addition, the power storage device described in Document 1 can be charged only when the permanent magnet reciprocates only in one direction, so that it can be vibrated by hand, and shaken in the reciprocable direction. For example, it is not possible to charge the battery efficiently just by holding it without being aware of it.

  Therefore, the present invention can be efficiently charged at the same time without causing inconveniences such as generating abnormal noise simply by possessing and exercising, etc., and can be easily maintained at the time of failure and is easy to use and inexpensive. An object is to provide a power storage device.

  According to a first invention of a power storage device that solves the above-described problem, a movable permanent magnet that is formed in a long shape with both ends being N-pole and S-pole and is held movably, and the movable permanent magnet in the longitudinal direction A slide portion that is slidably held while maintaining the orientation of the north and south poles, a coil wound with a conductive wire so as to be positioned around the side of the movable permanent magnet that slides within the slide portion, and the coil And a capacitor connected to both ends of the lead wire, and a capacitor for charging the capacitor with an electromagnetically induced electromotive force generated by reciprocating movement of a movable permanent magnet that can slide in the slide portion. In addition, a repulsion means is provided at both ends of the slide portion to accumulate the kinetic energy of the movable permanent magnet that slides inside and moves back so as to push the movable permanent magnet back inward. It is intended to.

  In this invention, when the movable permanent magnet that slides within the slide portion stops at the end portion, for example, when a spring is disposed as a repulsion means at both ends of the slide portion, the movable permanent magnet that moves is The contacted spring is gradually decelerated while being reduced and stopped. Thereafter, the spring reduced by the kinetic energy of the movable permanent magnet is repelled by being extended, and the sliding of the movable permanent magnet in the opposite direction is started. Therefore, the movable permanent magnet does not collide with both ends and is stopped, and the movement when reciprocating can be promoted, so that the change of magnetic flux passing through the coil can be accelerated, and the power generation can be efficiently generated. Can be charged.

  In addition to the specific matter of the first invention, the second invention of the power storage device that solves the above-mentioned problem is that the repulsion means is an S pole or N that repels the N pole or S pole of a movable permanent magnet that slides inside. A fixed permanent magnet is fixed to both ends of the slide portion so that the poles face each other.

  In the present invention, as the repelling means at both ends of the slide portion, the magnetic poles are opposed to each other so that the fixed permanent magnet is repelled by the movable permanent magnet, and the movable permanent magnets are separated from each other by approaching the fixed permanent magnet. The repulsive force increases according to the distance and gradually decelerates to stop. Thereafter, the movable permanent magnet is pushed back by a repulsive force corresponding to the magnetic flux density that increases closer to the kinetic energy of the movable permanent magnet, and sliding in the opposite direction is started. Therefore, unlike the repulsion means such as a spring, the movable permanent magnet can be reciprocated in a non-contact manner (without colliding) at both ends, and the repulsive force is not reduced permanently. The battery can be reciprocated to charge the battery efficiently.

  In addition to the specific matters of the first or third invention, the third invention of the power storage device that solves the above-mentioned problems is a movable permanent magnet with a rectifier interposed between both ends of the conductor of the coil and the battery. A DC electromotive force generated as the magnet slides in the forward / reverse direction is rectified so that the battery can be charged.

  In this invention, the electromagnetically induced electromotive force generated by the reciprocating motion of the movable permanent magnet in the slide portion (coil) is rectified and charged in the battery. Therefore, the accumulator can be charged without waste with the generated DC electromotive force.

  According to a fourth invention of a power storage device that solves the above problems, in addition to the specific matters of the third invention, a power generation unit including the movable permanent magnet, a slide portion, a coil, and a fixed permanent magnet, a rectifier, and a capacitor It is configured as a separate part.

  In the present invention, separate power generation units, rectifiers and capacitors are assembled by being electrically connected. Therefore, even if any of the power generation unit, the rectifier, or the capacitor fails, it can be repaired by replacing the failed part without disassembling the whole.

  According to a fifth invention of a power storage device that solves the above problems, in addition to the specific matters of any of the first to fourth inventions, a plurality of power generation units comprising the movable permanent magnet, a slide portion, a coil, and a fixed permanent magnet are provided. The movable permanent magnet is installed so that the sliding direction of the movable permanent magnet is a plurality of directions, and the conductive wires of the individual coils are connected in parallel.

  In the present invention, the sliding directions of the plurality of movable permanent magnets can be varied. Therefore, when moving, the power storage unit can generate power and charge the battery.

  A sixth invention of a power storage device that solves the above-described problems includes, in addition to the specific matters of any of the first to fifth inventions, a means for connecting the power charged in the battery to the outside so that the power can be output. It is a feature.

  In the present invention, the stored electric power can be output to the outside while charging the accumulator with the generated electromagnetic induction electromotive force. Therefore, it is possible to automatically charge the power supplied to the apparatus main body by being mounted on the portable device, and the portable device can be used without worrying about running out of the battery.

  In addition to the specific matters of any of the first to sixth inventions, a seventh invention of a power storage device that solves the above-described problem includes any one of the extremities that reciprocate or a means that is attached to an external device. It is a feature.

  In this invention, it can be attached to a human or animal limb or a moving mechanical device. Therefore, it is possible to charge the storage battery with necessary power without performing an operation for charging the storage battery.

  Here, it goes without saying that the capacitor may be configured to be externally connected. For example, the capacitor may be separately prepared and used. Furthermore, the power storage device of the present invention can be mounted as the battery of the mobile device itself, or the battery of the mobile device can be used as a power storage device according to the present invention and the power storage device main body side can be used as a charging device.

  As described above, according to the present invention, the movable permanent magnet slides and reciprocates within the slide portion only by providing repelling means such as a spring or a fixed permanent magnet at both ends of the slide portion of the movable permanent magnet. At both ends in the slide part when the capacitor is charged with the electromagnetic induction electromotive force generated in the coil, the movable permanent magnet is repelled and pushed back by the accumulated kinetic energy as it approaches the both ends of the slide part. The movable permanent magnet can be effectively slid using the motion applied from the outside, and the movable permanent magnet can be quickly moved in the coil. Therefore, the movable permanent magnet can be efficiently generated and charged in the battery without causing an abnormal noise by colliding with both end portions of the slide portion. In addition, by preparing a plurality of movable permanent magnets with different sliding directions, it is possible to charge efficiently, and by making the component parts separate parts, they can be easily replaced to improve maintainability. . As a result, a convenient power storage device can be provided at low cost.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described with reference to the drawings. 1-3 is a figure which shows 1st Embodiment of the electrical storage apparatus which concerns on this invention.

  In FIG. 1, a power storage device 10 generates power generation unit 11 that generates positive and negative DC power according to applied motion, and direct current power from the power generation unit 11 according to the direction of motion, for example, while maintaining positive voltage power. A rectifier 12 that performs rectification processing for converting negative voltage power into positive voltage power as well as input / output, and a battery that can charge and store DC power sent from the power generation unit 11 via the rectifier 12 ( The battery 13).

  The power generation unit 11 includes a movable permanent magnet 21 formed in a thin and long prismatic shape so that the N pole and the S pole appear at both ends, and the orientation of the N pole and the S pole by incorporating the movable permanent magnet 21. The magnetic poles repel each other with respect to the internal movable permanent magnet 21 at both ends of the slide portion 22 and the slide portion 22 formed in a rectangular tube shape so as to be slidably held in the longitudinal direction while maintaining the posture of maintaining the A fixed permanent magnet (repulsion means) 23 fixed in a state in which the same poles are opposed to each other (a state in which N and S poles are opposed), and a conductive wire 24a is wound around the side surface of the slide portion 22. And a coil 24 that generates an electromagnetic induced electromotive force in accordance with the moving direction of the movable permanent magnet 21 that slides back and forth inside the conductor. Both ends of a is connected to the battery 13 through the rectifier 12. Needless to say, the movable permanent magnet 21 is not limited to a prismatic shape, but may be other shapes such as a cylindrical shape.

  Thereby, when the power generation unit 11 moves in the extending direction of the slide portion 22 as a whole, the internal movable permanent magnet 21 slides in the direction corresponding to the movement and moves in the coil 24 by the inertial force. Electromagnetically induced electromotive force corresponding to a change in magnetic flux accompanying the movement of the movable permanent magnet 21 is generated in the coil 24 and can be charged (stored) in the battery 13 via the rectifier 12.

  At this time, the movable permanent magnet 21 slides in one direction in the slide portion 22 and approaches the fixed permanent magnet 23. However, as the separation distance increases, the repulsive force increases and stops instantaneously. Bounced back (pushed back). When the entire movement in the opposite direction has started, the speed of sliding in that direction is accelerated (the movement is promoted), and the change in the magnetic flux passing through the coil 24 can be accelerated, thereby efficiently generating power. Thus, the battery 13 can be charged. The approach distance with the fixed permanent magnet 23 depends on the sliding speed (kinetic energy) of the movable permanent magnet 21. The higher the speed, the closer to each other (accumulating kinetic energy) and the opposite direction with a strong repulsive force. Bounce back and slide. In addition, the movable permanent magnet 21 and the fixed permanent magnet 23 can be brought into non-contact by having a certain degree of magnetic strength, depending on the magnetic force thereof, and the repulsive force of each other is not reduced.

  Therefore, in the power generation unit 11, the electromagnetic induction electromotive force can be effectively generated in the coil 24, and the battery 13 can be charged efficiently. Further, the movable permanent magnet 21 can be reciprocated while permanently avoiding the collision with the fixed permanent magnet 23, and can be charged and stored in the battery 13 comfortably without generating an unpleasant collision sound. Can do.

  Here, the movable permanent magnet 21 and the fixed permanent magnet 23 are preferably selected from neodymium magnets so as to generate high-density magnetic flux and efficiently generate electromagnetic induction electromotive force, and the slide portion 22. May be made by molding plastic so that the movable permanent magnet 21 slides smoothly inside the coil 24 without passing through the coil 24, and the inside is coated with fluorine. Also good.

  As shown in FIG. 2, the rectifier 12 is a general single-phase bridge rectifier circuit in which a diode 26 is connected in a bridge shape. Both ends of a conducting wire 24a drawn from a coil 24 are connected to the input side, while the output side A battery 13 is connected. When the movable permanent magnet 21 slides in the forward / reverse direction in the slide portion 22 and reciprocates in the coil 24, the rectifier 12 has a positive or negative DC electromotive force according to the slide direction of the movable permanent magnet 21. Is generated in the coil 24, and can be charged without waste by inverting the sign of the electromotive force in accordance with the connection electrode of the battery 13 by the bridge type diode 26. The rectifier 12 is provided with a capacitor 27 on the output side connected to the battery 13, and the electromotive force rectified by the capacitor 27 can be smoothed to charge the battery 13.

  The power storage device 10 is configured as a separate part (cell part) for connecting and assembling the power generation unit 11, the rectifier 12 and the battery 13 in a replaceable manner. For example, as shown in FIG. When designed to be usable as a battery, the power generation unit 11 is designed to be connected to a cover member 31 in which the rectifier 12 and the battery 13 are detachably incorporated. Further, the cover member 31 is provided with an external connection terminal 32 that is connected to the charging connection terminal 101 of the mobile phone device 100 and outputs the power stored in the battery 13 to the outside. In addition, the power storage device 10 is provided with, for example, a rubber band 33 as a means for attaching to the moving part. By using the rubber band 33, a hand or a foot of a person who uses the mobile phone device 100 ( It can be attached to instruments that reciprocate.

  As a result, the power storage device 10 can naturally store electric power in the battery 13 without performing an operation such as applying a special vibration to charge the battery 13. Therefore, it is possible to use the mobile phone device 100 without worrying about running out of the battery simply by attaching the power storage device 10, and also in a place where there is no commercial power source to which the accessory charger is connected. The mobile phone device 100 can be used by functioning as an emergency battery. In addition, when any of the power generation unit 11, the rectifier 12 or the battery 13 of the power storage device 10 breaks down, the entire unit is not disassembled as in the case where the entire unit is designed integrally. Can be easily replaced and repaired.

  When the power storage device 10 is connected to a device having its own battery such as the mobile phone device 100, for example, a switch for disconnecting power supply to an external device is provided, or the battery power of each other The power supply may be designed to start according to the situation.

  As described above, in the present embodiment, the fixed permanent magnet 23 that repels the movable permanent magnet 21 is fixed to both ends of the slide portion 22 and the movable permanent magnet 21 reciprocates (slides) (battery). 13), when the electromagnetic induction electromotive force charged in the coil 24 is generated in the coil 24), the repulsive force between the permanent magnets 21 and 23 collides with the fixed permanent magnet 23 at the end, and the opposite direction is made at high speed. The battery 13 can be charged and stored efficiently without causing unpleasant noise (collision / damage noise). Further, even if a component such as the power generation unit 11 breaks down, the component can be replaced and restored, and can be used as an inexpensive power storage device 10 that is easy to maintain and easy to use.

  As another aspect of the present embodiment, in the above-described embodiment, a case where the mobile phone device 100 having a battery is connected is described. However, the present invention is not limited to this. For example, the power storage device 10 may be attached to the battery mounting portion of the mobile phone device 100 so as to function as the battery, or as a charging device that directly charges the battery of the mobile phone device 100 without the battery 13. It can also be made available.

In addition, since this embodiment is comprised substantially the same as the above-mentioned embodiment, the same code | symbol is attached | subjected to the same structure and a characteristic part is demonstrated.

  In FIG. 4, the power storage device 40 includes a plurality of power generation units 11 connected in parallel and is connected to a battery 13 via a rectifier 12, and the power generation unit 11 slides the movable permanent magnet 21 in the slide portion 22. The directions are arranged in parallel so as to be orthogonal to a plurality of directions, for example. Note that the power generation units 11 may be arranged in a pattern shown in FIG. 5 so as to have an even positional relationship. Moreover, you may make it the slide part 22 face in more directions or random directions.

  Accordingly, the power storage device 40 includes a plurality of power generation units 11 and can individually generate power, and the direction of movement is made by making the sliding direction of the movable permanent magnet 21 of the power generation unit 11 orthogonal (different). Therefore, at least one of the movable permanent magnets 21 can be slid to generate power without being influenced by the power, and the battery 13 can be charged effectively.

  As described above, in the present embodiment, in addition to the effects of the above-described embodiment, at least the movable permanent magnet 21 in any one of the slide portions 22 is used by effectively utilizing a motion that is not conscious of charging. The battery 13 can be slid, and the battery 13 can be charged and stored more efficiently.

  As another aspect of the present embodiment, in the above-described embodiment, the case where the power generation units 11 are arranged in a pattern extending in the planar direction will be described. However, the present invention is not limited to this. For example, the power generation units 11 may be stacked. Alternatively, the movable permanent magnet 21 in the slide portion 22 may slide in three-dimensional different directions.

  Moreover, although the above-mentioned embodiment demonstrates the case where the fixed permanent magnet 23 is fixedly provided in the both ends of the slide part 22 as a means to repel the movable permanent magnet 21, it is not restricted to this, For example, a movable permanent magnet An elastic member such as a spring that expands and contracts in the sliding direction of 21 may be disposed. However, in this case, since it is repeatedly expanded and contracted by the kinetic energy of the movable permanent magnet 21, it is preferable to configure as in the above-described embodiment from the viewpoint of durability.
