Description

  The present invention relates to a vibration dynamo device and a power supply device.

  Conventionally, as a power generation method for converting vibration energy into electric energy, there are a method using electromagnetic induction, a method using a piezoelectric element, a method using electrostatic induction, and the like. The system using electromagnetic induction is a system in which the relative position between the coil and the magnet is changed by vibration and power is generated by electromagnetic induction generated in the coil. Examples of such a technique include US Pat. No. 6,220,719 (Patent Document 1).

  Specifically, Patent Document 1 discloses a cylindrical member, a coil disposed along the cylindrical member, a magnet provided in the cylindrical member so as to be capable of reciprocating in the longitudinal direction, and both ends of the cylindrical member. A flashlight comprising a repelling magnet arranged is disclosed.

US Pat. No. 6,220,719

  However, the present inventors paid attention to the problem that the power generation efficiency of the flashlight disclosed in Patent Document 1 is poor, and made this a problem. That is, an object of the present invention is to provide a vibration dynamo device and a power supply device that improve power generation efficiency.

  The present inventor has the problem that the power generation efficiency in the flashlight of Patent Document 1 is poor because the cylindrical member is too long. Therefore, the power generation that converts the kinetic (vibration) energy of the magnet that reciprocates inside the cylindrical member into electric power energy. We found out that it was caused by the inefficiency. For this reason, the present inventor completed the present invention as a result of earnest research to generate a high electromotive force with a small momentum.

  That is, the vibration dynamo device of the present invention is a cylindrical member that is capable of reciprocating along a non-magnetic cylindrical member, a coil disposed on the outer periphery of the cylindrical member, and the extending direction of the cylindrical member. And a pair of repulsive members including magnets and a pair of repelling members disposed at both ends in the extending direction of the cylindrical member and including magnets that repel magnetic repulsion. L1 + 1.00 × L2 ≦ L0 ≦ L1 + 4.20 × L2 (L1 + 1.00 × L2 ≦ L0 ≦ L1 + 4.20 × L2) where L0 is the length in the extending direction between them, L1 is the length in the extending direction of the coil, and L2 is the length in the extending direction of the vibration member. L2 ≦ L1).

  Based on the principle that the magnet generates an electromotive force by passing through the coil, the inventor needs to pass a predetermined length in the vibrating member through the coil in order to increase the electromotive force. The distance that the vibration member can move inside the tubular member, that is, the length L0 between the pair of repulsion members is considered to be required to be a predetermined value or more. Therefore, as a result of intensive studies conducted by the inventor to increase the electromotive force, it has been found that a high electromotive force can be generated when 0.50 times or more of the length L2 of the vibrating member passes through the coil. Further, the present inventor considers that the length L0 between the pair of repulsion members needs to be a predetermined length or less in order to reduce the amount of reciprocation that the vibration member returns after passing through the coil. It was. Therefore, as a result of the present inventors diligently researching to reduce the momentum of the vibration member, the distance that the vibration member that has passed through the coil moves to the repulsion member is 2.10 times or less the length L2 of the vibration member. It was found that an electromotive force can be generated with a low momentum.

  According to the vibration dynamo device of the present invention, the length L0 between the pair of repulsive members is L1 + 1.00 × L2 = L1 + 0.50 × L2 × 2 or more, and therefore vibration for a length of 0.50 times or more. The member can pass from one end (the other end) of the coil toward the repulsion member at the one end (the other end). For this reason, an electromotive force can be improved. Further, since the length L0 of the pair of repulsive members is L1 + 4.20 × L2 = L1 + 2.10 × L2 × 2 or less, the coil is directed from one end (the other end) to the one end (the other end). Thus, the length that the vibrating member moves is 2.10 times or less the entire length of the vibrating member. For this reason, an electromotive force can be generated with a small momentum. Furthermore, in this invention, since the repulsion member is arrange | positioned at the both ends of the cylindrical member, when a vibration member approaches a repulsion member, a magnetic repulsion can be made to move away from a vibration member. For this reason, the reciprocating motion of the vibration member can be made more efficient. Therefore, according to the vibration dynamo device of the present invention, a high electromotive force can be generated with a small momentum, so that power generation efficiency can be improved.

  In the vibration dynamo device of the present invention, preferably, the portion of the vibration member that contacts the cylindrical member is a sphere.

  The present inventor has the problem that the power generation efficiency is poor in the flashlight of Patent Document 1 described above, because the magnet of Patent Document 1 has the same cross-sectional shape as the space inside the tubular member. It was further found out that the sliding resistance between the cylindrical member and the magnet is large when the magnet reciprocates.

  In the present invention, when the vibrating member reciprocates and the portion of the vibrating member that contacts the cylindrical member is a sphere, the sliding portion between the vibrating member and the cylindrical member is in point contact. For this reason, since the sliding area of a vibration member and a cylindrical member can be reduced, the resistance at the time of a vibration member vibrating can be reduced. Therefore, since the efficiency of converting kinetic energy into electric energy can be improved, the power generation efficiency can be further improved.

  In the vibration dynamo device of the present invention, preferably, the vibration member includes three or more elements, and the elements positioned at both ends are spheres.

  When the sphere constituting the vibrating member contacts the cylindrical member when the vibrating member reciprocates, the contact area can be reduced. For this reason, the vibration dynamo device which can improve power generation efficiency more is realizable.

  In the vibration dynamo device of the present invention, preferably, the remaining portions of the three or more elements are spheres and / or columns, and the outer diameters of the spheres located at both ends are larger than the outer diameters of the remaining spheres and / or columns. Is also big.

  Thereby, since the spherical body located in both ends contacts with a cylindrical member among the elements which comprise a vibration member, the contact area of a vibration member and a cylindrical member at the time of a vibration member reciprocating can be reduced more. For this reason, the power generation efficiency of the vibration dynamo device can be further improved.

  In the vibration dynamo device of the present invention, preferably, the spheres located at both ends are yokes, and the remainder of the three or more elements is a magnet.

  By combining the yoke and the magnet, the magnetic force can be used effectively and the attractive force is improved. For this reason, the power generation efficiency of the vibration dynamo device can be further improved.

  In the vibration dynamo device of the present invention, the vibration member may be composed only of a magnet. Even in this case, when the vibrating member reciprocates, the spherical body of the magnet constituting the vibrating member is in contact with the cylindrical member, so that the contact area between the cylindrical member and the vibrating member can be reduced. For this reason, the power generation efficiency of the vibration dynamo device can be improved.

  The vibration dynamo device of the present invention may further include an output terminal connected to the external terminal. Thereby, the electromotive force generated in the vibration dynamo device can be transmitted to the external device having the external terminal.

  In the vibration dynamo device of the present invention, preferably, the output terminals are respectively disposed outside the pair of repulsion members. Thereby, size reduction of a vibration dynamo device provided with an output terminal can be achieved.

  In the vibration dynamo device of the present invention, preferably, at least one of the output terminals is attracted and held by the magnetic force of the magnet of the repulsion member. Thereby, size reduction of a vibration dynamo device provided with an output terminal is easily realizable.

  Preferably, the vibration dynamo device of the present invention further includes a rectifier circuit that transmits an alternating current generated in the coil, and a rechargeable battery that charges the direct current rectified by the rectifier circuit.

  Since the current generated in the coil by the rectifier circuit can be converted to direct current, the rechargeable battery can be charged. Thereby, a rechargeable battery can be used when needed.

  The power supply device of the present invention includes the above-described vibration dynamo device. Since the vibration dynamo device can improve the power generation efficiency, the power generation efficiency of the power supply device can also be improved.

  The power supply device of the present invention is preferably incorporated in a housing provided in an external device having an external terminal. Thereby, the power supply device of this invention can be easily used as a power supply device of an external device.

  In the power supply device of the present invention, the output terminal may be connected to a terminal of a remote controller (remote controller) as an external terminal. Thus, the power supply device of the present invention can be suitably used for a remote controller.

  According to the vibration dynamo device and the power supply device of the present invention, the power generation efficiency can be improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following drawings, the same or corresponding parts are denoted by the same reference numerals, and description thereof will not be repeated.

(Embodiment 1)
A vibration dynamo apparatus according to an embodiment of the present invention will be described. The vibration dynamo device 1 according to the present embodiment includes a tubular member 2, a coil 3 disposed on the outer periphery of the tubular member 2, a vibration member 10 accommodated in the tubular member 2, and a tubular member. 2 is provided with a pair of repulsive members 4 disposed at both ends, a casing 5 surrounding the coil 3, and covering members 7 disposed at both ends of the cylindrical member 2 and both ends of the repelling member 4. .

  The cylindrical member 2 has a hollow rod shape inside and is open at both ends. The cylindrical member 2 of the present embodiment extends in the left-right direction (the direction of arrow A in FIG. 1) in FIG. In addition, the outer shape and inner shape (hollow shape) of the cylindrical member 2 are not specifically limited, A circular shape, a rectangular shape, etc. are mentioned in cross-sectional view. The cylindrical member 2 of the present embodiment has an outer shape and an inner shape that are circular in a cross-sectional view. Note that the inner diameter (hollow diameter) of the cylindrical member of the present embodiment is slightly larger than the outer diameter of the vibration member 10 described later.

  The cylindrical member 2 is formed of a nonmagnetic material. The non-magnetic material is a material that is not a ferromagnetic material, and includes a paramagnetic material, a diamagnetic material, and an antiferromagnetic material. Examples of the non-magnetic material include metals such as aluminum and synthetic resins such as plastic.

  A coil 3 is wound around the outer periphery of the cylindrical member 2. For this reason, the cylindrical member 2 also serves as a bobbin for the coil 3. The coil 3 of the present embodiment is provided at the center of the cylindrical member 2, and the length between one end of the cylindrical member 2 and one end of the coil 3 is the same as that of the other end of the cylindrical member 2 and the coil. 3 is the same length as the other end. The coil 3 is a solenoid coil, for example.

  A vibration member 10 is provided inside the tubular member 2 in a state where reciprocation is possible along the extending direction of the tubular member 2 (the direction of arrow A in FIG. 1). Since the coil 3 is disposed on the outer periphery of the cylindrical member 2, the vibrating member 10 reciprocates inside the coil 3. The vibrating member 10 includes a magnet, and the coil 3 generates a voltage by the reciprocating motion of the vibrating member 10. That is, since the vibrating member 10 reciprocates along the winding axis direction of the coil 3, an alternating current is generated in the coil 3. The length L2 in the extending direction of the vibration member 10 is shorter than or the same as the length L1 in the extending direction of the coil 3 (L2 ≦ L1). The vibration member 10 will be described later.

  Repulsive members 4 are respectively provided at both ends of the cylindrical member 2. The repulsive member 4 of the present embodiment closes the openings at both ends of the cylindrical member 2. For this reason, the vibrating member 10 that reciprocates is accommodated in the cylindrical member 2 by the pair of repulsive members 4. That is, the vibrating member 10 reciprocates between the pair of repulsive members 4. In addition, the repulsion member 4 arrange | positioned at the one end of the cylindrical member 2 and the repulsion member 4 arrange | positioned at the other end of the cylindrical member 2 are the same members.

  The repulsive member 4 includes a vibrating member 10 and a magnet that repels magnetically. The repulsion member 4 magnetically repels the vibration member 10 approaching the repulsion member 4 toward the central portion facing the coil 3. That is, the polarity of the magnet constituting the repulsion member is arranged so as to be magnetically repulsive with the vibration member.

  The repulsive member 4 is not particularly limited as long as it includes a magnet. For example, the repulsive member 4 may be only a magnet, may further include a yoke disposed at the end of the magnet, and may be provided on the end surface on the center side of the magnet. You may further provide the arrange | positioned cushioning material. Normally, the vibration member 10 does not contact the repulsion member 4 by the magnet of the repulsion member 4, but if a cushioning material is further provided, damage to the vibration member 10 can be reduced when it comes into contact. For this reason, it is preferable that the cushion material is formed of an elastic body such as resin or rubber.

  The covering member 7 covers the released both ends of the cylindrical member 2 and the repulsive member 4. The covering member 7 is made of a nonmagnetic material.

  A housing 5 is provided to accommodate the vibration member 10, the cylindrical member 2, the coil 3, the repulsion member 4, and the covering member 7. The housing 5 is made of a nonmagnetic material. The cylindrical member 2, the coil 3, the repulsion member 4, the housing 5 and the covering member 7 are arranged line-symmetrically.

  The vibration dynamo device 1 may further include a rectifying unit, a charging unit, and the like connected to the coil 3 (not shown).

  As shown in FIG. 1, when the length in the extending direction between the pair of repulsive members 4 is L0, the length in the extending direction of the coil 3 is L1, and the length in the extending direction of the vibration member 10 is L2, L1 + 1.00 × L2 ≦ L0 ≦ L1 + 4.20 × L2 (L2 ≦ L1). Specifically, when α is a constant, the lower limit value of the constant α is 0.50 or more, preferably 0.74 or more in the formula L0 = L1 + α × L2 × 2, and is around 1.00 It is more preferable that The upper limit value of the constant α is 2.10 or less, preferably 1.78 or less, and more preferably 1.20 or less. Α is a value obtained by rounding off the third decimal place.

  Here, the vibration member 10 will be described in detail with reference to FIGS. A portion of the vibrating member 10 that contacts the cylindrical member 2 is a sphere.

  As shown in FIGS. 1 to 5, the vibration member 10 includes three or more elements 11 a, 11 b, 12 a, 12 b, 13 a, 13 b, 14 a, 14 b, and the three or more elements are in a reciprocating direction. They are arranged in parallel along the direction of arrow A in FIG. Of the three or more elements, the elements 11a, 11b, 12a, 12b located at both ends are spheres. The remaining parts of the three or more elements, that is, the elements 13a, 13b, 14a, and 14b located at positions other than both ends (center part) are pillars in the structure (elements 13a and 14a) shown in FIGS. And in the structure (element 13b, 14b) shown in FIG. 5, it is a sphere. Note that the sphere and the column include those whose outer shape means a sphere and a column, and whose inside is a cavity. Further, the column includes a cylinder, a prism, a disk shape, and the like, and is a cylinder in the present embodiment.

  As shown in FIGS. 1 to 5, the outer diameters of the spheres located at both ends are larger than the outer diameters of the remaining spheres and / or pillars. In this case, the spheres located at both ends serve as portions in contact with the cylindrical member 2 in the vibration member 10. In the vibrating member 10, the outer diameters of the two spheres positioned at both ends are substantially the same. Substantially the same means that each of the two spheres at both ends contacts the cylindrical member when the vibrating member 10 reciprocates.

  The outer diameter of the sphere is a diameter. The outer diameter of the column is the diameter of the circle on the bottom surface in the case of a cylinder, and the diameter of the circumscribed circle on the bottom surface when the bottom surface of the column is an n-gon (n is an integer of 3 or more).

  In the structure shown in FIGS. 1, 3 and 5, the spheres located at both ends (elements 11a and 12a in FIGS. 1, 3 and 5) are yokes, and the remainder of three or more elements (elements in FIG. 1). 13a, elements 13a, 13b, 14a, 14b) in FIGS. 3 and 5 are magnets. In the structure shown in FIGS. 2 and 4, the elements constituting the vibration member 10 (the elements 11b, 12b, 13a, and 14a in FIG. 2, and the elements 11b, 12b, 13b, and 14b in FIG. 4) are made only of magnets. When the elements constituting the vibration member 10 are composed of magnets or are composed of magnets and yokes as described above, the three or more elements of the present embodiment are held by magnetic attraction. These are formed only by magnets or only by magnets and yokes, and hold each other only by magnetic attraction.

  In addition, a magnet (magnet) is a permanent magnet. The magnet is magnetized in the reciprocating direction (axial direction). The magnetization (magnetization) method is not particularly limited. For example, there is a method in which a magnet material is fixed at the center of the air-core coil, a pulse high current is passed, and magnetization is performed in the axial direction. The material of the magnet is not particularly limited, but it is preferable to use a Nd—Fe—B sintered magnet from the viewpoint of showing a high magnetic force.

  Further, the yoke is a soft iron that amplifies the attractive force of the magnet, and may contain iron and includes a soft magnetic material. In the present embodiment, a steel ball is used as the spherical yoke.

  In addition, the vibration member 10 shown in FIGS. 1-5 is an illustration, Comprising: The part which contact | connects the cylindrical member 2 does not need to be a spherical body. Further, even when the portion in contact with the cylindrical member 2 is a sphere, the configuration is not particularly limited. For example, the vibration member 10 includes two elements, and the two elements are magnet spheres. There may be.

  The vibrating member 10 is not particularly limited as long as the vibrating member 10 has a size that can freely reciprocate within the cylindrical member 2, but the cylindrical member 2 and the vibrating member 10 of the vibrating dynamo device 1 including the vibrating member 10 illustrated in FIG. 5. An example of the specific dimensions is given. The outer diameter of the cylindrical member 2 is, for example, 13 mm, and the inner diameter of the cylindrical member 2 is, for example, 11 mm. The outer diameter of the spheres (elements 11a and 12a) located at both ends of the vibration member 10 is, for example, 10 mm. The repulsive member 4 is, for example, a magnet having an outer diameter of 13 mm and a thickness of 1.5 mm. The remaining spherical body (elements 13b and 14b) located at the center of the vibration member 10 has an outer diameter of 9.5 mm.

  Next, the operation of the vibration dynamo device 1 of the present embodiment will be described mainly with reference to FIG.

  First, the casing 5 of the vibration dynamo device 1 is held and reciprocates along the extending direction of the cylindrical member 2, that is, the arrow A in FIG. Thereby, the vibration member 10 reciprocates along the extending direction of the cylindrical member 2 inside the cylindrical member 2. As a result, the vibration member 10 reciprocates so as to pass through the coil 3 disposed on the outer periphery of the cylindrical member 2, so that the magnetic flux lines generated from the magnet of the vibration member 10 are orthogonal to the coil 3. At that time, an induced current is generated as an induced electromotive force. Since the magnet included in the vibrating member 10 repeatedly enters and exits the coil 3, an alternating current is generated in the coil 3.

  The alternating current generated in the coil 3 is transmitted to a rectification unit (not shown) via wiring (not shown) connected to both ends of the coil. Full-wave rectification is performed by the rectification unit to rectify an alternating current into a DC power source, and the battery is charged by a charging unit (not shown). The charged current is output to the outside through an electrode (not shown). The current output to the outside is supplied to the load of the external device and is driven (operated) by the supplied current.

  In the present embodiment, in the reciprocating motion of the vibration member 10 in the cylindrical member 2, when the vibration member 10 jumps out of the coil 3 and moves toward the repulsion member 4, the vibration member 10 is repelled in the vicinity of the repulsion member 4. A magnetic repulsive force is generated with the member 4, and the repulsive force accelerates the movement of the vibrating member 10 to return to the central portion. For this reason, the reciprocating motion of the vibration member 10 can be performed efficiently. That is, the force applied to the vibration dynamo device 1 to reciprocate the vibration member 10, that is, the energy required for the reciprocation of the vibration member 10 can be reduced.

  The length L0 between the pair of repulsive members 4 that is the maximum length that the vibration member 10 reciprocates is L1 + 4.20 × L2 (= L1 + 2.10 × L2 × 2) or less. That is, the length that the vibration member 10 moves from one end of the coil 3 toward the repulsion member 4 at one end, and the length that returns from the vicinity of the repulsion member 4 to the coil 3 located in the center ((L0-L1) / 2) is 2.10 times or less of the length L2 of the vibration member 10. For this reason, since the reciprocating length of the vibration member 10 can be shortened, there is little waste in the kinetic energy of the vibration member 10 converted into electric energy by the coil 3. From the viewpoint of reducing waste, it is preferably L1 + 1.78 × L2 × 2 or less, and more preferably L1 + 1.20 × L2 × 2 or less. In addition, when L1 + 4.20 × L2 is exceeded, the energy required for reciprocating the vibration member 10 also increases (in this embodiment, the vibration dynamo device needs to be greatly shaken).

  The length L0 between the pair of repulsive members 4 is equal to or longer than L1 + 1.00 × L2 (= L1 + 0.50 × L2 × 2). For this reason, since 0.50 times or more of the length L2 of the vibration member 10 passes through the coil 3, a high electromotive force can be generated. From the viewpoint of generating a higher electromotive force, it is preferably L1 + 0.55 × L2 × 2 or more, more preferably L1 + 0.74 × L2 × 2 or more, and L1 + 1.00 × L2 × 2 or more. It is even more preferable.

Thus, since the high electromotive force can be generated by the coil 3 with a small momentum by the vibration member 10, the power generation efficiency of the vibration dynamo device 1 can be improved.

  In the present embodiment, when the vibration member 10 reciprocates in the cylindrical member 2, the spheres positioned at both ends, which are elements of the vibration member 10, are in contact with the cylindrical member 2. The vibrating member 10 slides in a state of point contact with the member 2. Thereby, since the sliding area of the vibration member 10 and the cylindrical member can be reduced, the contact resistance (sliding resistance) is reduced. Since the vibration member 10 is easy to move, the kinetic energy of the vibration member 10 due to the force applied to the vibration dynamo device 1 can be efficiently converted into electric energy by the coil 3. Therefore, since the power generation efficiency of the vibration dynamo device 1 can be further improved, the amount of electricity generated can be increased.

  In the present embodiment, as shown in FIG. 5, the vibration member 10 includes three or more elements 11a, 12a, 13b, and 14b. Each of the three or more elements is a sphere, and spheres positioned at both ends. It is preferable that the outer diameter of the (elements 11a and 12a) is larger than the outer diameter of the remaining spheres (elements 13b and 14b), the spheres located at both ends are yokes, and the remaining spheres are magnets. As a result, the contact resistance between the vibrating member 10 and the cylindrical member 2 during the reciprocating motion of the vibrating member 10 can be reduced, and the generated magnetic force can be reduced by having the yoke effect of the central magnet and the yokes located at both ends. Since it can raise, power generation efficiency can be improved more. Further, since the vibration member 10 is made of a sphere, the cost can be reduced.

It was 2.10 times or less of the length L2, and the momentum was small. On the other hand, in the sample 6 where L1 + 2.20 × L2 × 2 = L0, the distance (L0−L1) / 2 from one end of the coil 3 to the repelling member at one end is 88 mm, and the length L2 of the vibrating member 10 = Momentum exceeding 2.10 times of 40 mm.

  Therefore, in order to generate a large electromotive force with a small momentum in a vibration dynamo device in which repulsive members are arranged at both ends of a cylindrical member, L1 + 0.50 × L2 × 2 ≦ L0 ≦ L1 + 2.10 × L2 × 2 (L2 It was found necessary to have a relationship of ≦ L1).

  Specifically, in the vibration dynamo devices of Samples 2 and 3, although the entire vibration member 10 does not protrude from the coil, the length of 0.50 times or more protrudes, so even a very small momentum has a high start. Was showing power. For this reason, it turned out that power generation efficiency can be improved.

  Further, the vibration dynamo device of Sample 5 showed a very high electromotive force with a small momentum because the entire vibration member jumped out of the coil and repeatedly entered and exited the coil. For this reason, it turned out that power generation efficiency can be improved.

  The vibration dynamo device of sample 4 had a very high electromotive force with a small momentum because almost the entire vibration member 10 repeated the reciprocating motion of popping out the coil and returning to the coil 3 as it was. Since the electromotive force of the vibration dynamo device of sample 4 was the same as that of samples 5 and 6, it was found that the power generation efficiency could be improved most. Therefore, it was found that the constant α in the equation L0 = L1 + constant α × L2 × 2 is most preferably around 1.00.

  The vibration dynamo device of sample 1 could generate an electromotive force with a small momentum, but the power generation efficiency was poor because the electromotive force was small.

  The vibration dynamo device of Sample 6 showed a high electromotive force, but the power generation efficiency was poor because the momentum of the vibration member was large.

  In addition, when the present inventor has a relationship of L0 = L1 + 2.10 × L2 × 2, the electromotive force is about 13 (Vp−p), and the momentum corresponds to C (the momentum is slightly small). I have knowledge.

  As described above, it is disposed at both ends in the extending direction of the cylindrical member, and includes a vibrating member and a pair of repulsive members including a magnet that repels magnetically, and the length in the extending direction between the pair of repelling members is L0, coil L1 is the length in the extending direction, and L2 is the length in the extending direction of the vibration member. By having a relationship of L1 + 1.00 × L2 ≦ L0 ≦ L1 + 4.20 × L2 (L2 ≦ L1), power generation It was confirmed that the efficiency could be improved.
