Description

Technical Field

[0001] The present invention relates to a portable self-generation device using a rack gear component and a pinion component, and more particularly to a portable self-generation device that can self-generate electricity in a small and efficient manner to charge a battery in emergency situations such as military operations, refugee camps, disasters caused by earthquakes, emergency situations on ships, outdoor activities, etc., where electricity is usually not available, and can be used in conjunction with a variety of smart modules. Background Art

[0002] Generally speaking, although electricity is used as the main energy source in industrial society, due to the depletion of fossil energy, various alternative power generation facilities such as solar power generation, wind power generation, and tidal power generation have been rapidly invested and developed. On the other hand, although the electricity produced by the power generation facilities is supplied to household and industrial devices or products through power cables and used as energy, most products such as small-scale home appliances and daily necessities that require portability or mobility have batteries such as primary batteries or secondary batteries as power sources.

[0003] In addition, as society develops rapidly, various electronic devices are developed, and the number of people using them is increasing. Recently, the use of portable electronic devices such as smartphones is increasing. In addition, due to the development of outdoor leisure culture such as fishing and hiking, the time spent outdoors is increasing, so there is a need for backup batteries.

[0004] However, since the battery has a limited usage time, it needs to be recharged once the power source is discharged. However, there is a problem that it cannot be recharged while moving or outdoors. In addition, if the battery is discharged, there is a problem that communication equipment for requesting help, electrical equipment for lighting, smartphones, tablet computers, laptop computers, etc. cannot be used in situations where there is no electricity supply, such as military operations, refugee camps, disasters caused by earthquakes, and emergencies on ships.

[0005] Therefore, recently, various proposals have been made for portable self-generating devices, which obtain electric energy consumed by various electronic devices used during outdoor activities such as military operations, fishing, and mountain climbing by self-generating electricity, and are being used. Such conventional portable self-generating devices, when generating electric energy, require additional actions such as a prescribed operation (rotational movement of an operating lever), so that they are inconvenient to use and require a lot of time. However, the amount of energy that can be obtained is extremely small, so there is a problem that they are not actually applicable to electrical equipment.

[0006] An example of a technology for solving these problems is disclosed in the following patent document.

[0007] For example, Figure 1 As shown, Korean Patent Publication No. 2009-0062090 (published on June 17, 2009, Patent Document 1) discloses a portable small-sized power generation device, which includes a linear power generation device having a piston rod 11 that reciprocates by power generated by a power generation mechanism, an actuator 1 disposed on the piston rod 11, and a stator 2 disposed in a manner surrounding the actuator 1 and having permanent magnets 21 and coils 22 disposed on the inner wall, wherein the actuator 1 has a length such that its end does not reach the end of one of the two permanent magnets 21 facing the coil 22 when the piston rod 11 fully moves in one direction.

[0008] In addition, Korean Patent Publication No. 2017-0018702 (published on February 20, 2017, Patent Document 2) discloses a power generation device, which includes: a rack; a pinion, which is configured to mesh with the above-mentioned rack and has a stator on the inner circumferential surface; a rotor, which is inserted into the above-mentioned pinion and is configured to be separated from the above-mentioned stator; a first rotor rotating unit, which uses the rotational force of the above-mentioned pinion generated when the above-mentioned rack moves linearly in one direction to rotate the above-mentioned rotor in one direction; and a second rotor rotating unit, which uses the reverse rotational force of the above-mentioned pinion generated when the above-mentioned rack moves linearly in another direction to rotate the above-mentioned rotor in the above-mentioned one direction.

[0009] On the other hand, Korean Patent Gazette No. 10-1596430 (authorized on February 16, 2016, patent document 3) applied for and authorized by the inventor discloses a self-generating device, which includes: a driving shaft that rotates alternately in a forward direction and a reverse direction by an external force; a forward power transmission part that transmits only the forward rotational force of the driving shaft to the generating shaft; a reverse power transmission part that transmits only the reverse rotational force of the driving shaft to the generating shaft; and a generator that generates electricity using the unidirectional rotational force of the generating shaft, wherein a pulley is provided on the driving shaft, and since the metal wire (wire) wound on the pulley of the driving shaft performs reciprocating motion alternately, the driving shaft can rotate alternately in a forward direction and a reverse direction. Summary of the invention

[0010] Problem to be solved

[0011] The technology disclosed in Patent Document 1 as described above discloses a piston rod that performs reciprocating motion by power generated by a power generating mechanism, but does not specifically describe the composition of the power generating mechanism to generate power, and there are problems such as unclear records of the composition and work that executes the reciprocating motion of the piston rod.

[0012] In addition, the technology disclosed in the above-mentioned patent document 2 is a power generation device that can generate electricity by utilizing vibrations transmitted from the road surface to the vehicle body through the vehicle. However, due to its poor portability for outdoor use, it has problems such as users cannot carry it with them and cannot generate electricity when necessary.

[0013] On the other hand, the technology disclosed in the above-mentioned Patent Document 3 has the risk of parts being damaged due to repeated use over a long period of time, and there are problems such as the metal wire wound around the pulley cannot work when it is in a loose state. Moreover, although power is generated by pulling the metal wire, there is a problem that the energy of the rewinding cannot be used. In addition, the technology disclosed in the above-mentioned Patent Document 3 also has the problem that a plurality of parts for supporting the metal wire are required according to the operation of the metal wire.

[0014] The present invention is made to solve the problems mentioned above, and its purpose is to provide a portable self-generating device that can generate electricity and charge the battery for a long time outdoors using one or two hands in situations such as military operations, refugee camps, disasters caused by earthquakes, emergencies on ships, fishing, mountain climbing, etc.

[0015] Another object of the present invention is to provide a portable self-generating device which, by providing a plurality of pinion components, can continuously generate electricity even if any of the pinion components is damaged.

[0065] In addition, the first rotating member and the second rotating member operate independently of each other, and the first rotating member and the second rotating member are made of the same parts, so the description of the first rotating member and the second rotating member is replaced by the description of one of the first rotating member and the second rotating member, and the symbols corresponding to the drawings are simply described in correspondence with the rotating member. In addition, the same reference numerals can be attached to the description of the components of the first rotating member and the second rotating member.

[0066] Hereinafter, embodiments of the portable self-generating device according to the present invention will be described with reference to the accompanying drawings.

[0067] First Embodiment

[0068] Figure 2 is a perspective view of the appearance of a portable self-generating device according to a first embodiment of the present invention, Figure 3 is a conceptual diagram of a portable self-generating device according to a first embodiment of the present invention, Figure 4 It is shown in Figure 3 Working diagram of the portable self-generating device, Figure 5 is shown in the diagram Figure 3 A top view of the configuration state of the rack and gear component and multiple pinion components.

[0069] like Figure 2 and Figure 3 As shown, in the portable self-generating device according to the first embodiment of the present invention, it includes a main body 100; a rack gear component 200, which performs linear reciprocating motion in the above-mentioned main body 100; a plurality of pinion components 300, which are arranged in the above-mentioned main body 100 and cooperate with the above-mentioned rack gear component 200, and rotate forward and reverse with the linear reciprocating motion of the above-mentioned rack gear component 200. The above-mentioned plurality of pinion components 300 each rotates forward or reverse in sequence with the linear reciprocating motion of the above-mentioned rack gear component 200.

[0070] like Figure 2 As shown, the main body 100 is substantially cylindrical, and a first opening 110 for the rack and pinion member 200 to enter and exit is provided at the upper portion of the main body 100, and a pair of support portions 120 are provided at the lower portion for the user to support with two feet when self-generating electricity. In addition, the main body 100 can be made of metal or formed of engineering plastic, i.e., polycarbonate. On the other hand, although Figure 2 The main body 100 is shown in FIG. 1 as being formed in a substantially cylindrical shape, but the present invention is not limited thereto and can be formed in a polyhedron such as a quadrilateral or a pentagon. Figure 2 As shown, the inner diameter of the main body 100 formed in a cylindrical shape can be changed according to the outer diameter of the pinion member, and is not limited to a specific size.

[0071] In addition, although Figure 2 , a structure in which the support part 120 is provided for supporting with two feet when in use is shown, but a structure in which the rack gear part 200 is operated with one hand and the main body 100 is held with the other hand can be set. For such holding, a shape for holding can also be provided in the substantially central part of the main body 100, for example, a finger shape can be provided. On the other hand, a guide part is provided in the main body 100 along the length direction of the rack gear part 200 to prevent the rack gear part 200 from deviating from the movement path when the rack gear part 200 performs linear motion.

Figure 2 As shown, a hook groove 221 for a user to hook the handle 220 with fingers is provided at the end of the handle 220 .

[0073] Therefore, if Figure 4 As shown in (a), the rack gear part 210 is pulled out from the body 100 by pulling the handle part 220, thereby each of the plurality of pinion parts 300 rotates in the clockwise direction. Figure 4 As shown in (b), the rack gear part 210 is inserted into the body 100 by pushing the handle part 220, thereby each of the plurality of pinion gear parts 300 rotates in the counterclockwise direction.

[0074] like Figure 5 As shown, the number of the helical teeth formed on the rack gear portion 210 is not limited, and the width thereof can be set to be smaller than the width of the helical teeth of the pinion gear.

Each pinion component is rotatably supported by two side walls in the body 100 through an axis. For this purpose, two side walls in the body 100 are provided with shaft insertion holes corresponding to the plurality of pinion components 300.

[0076] On the other hand, the rack and gear component 200 and the pinion component can also be made of the same material as the body 100, ie, metal material or engineering plastic, ie, polycarbonate.

The shape of the locking portion 230 is not specific, as long as it can achieve the function of preventing the rack gear portion 210 from passing through the first opening portion 110 of the body 100. In addition, although Figure 6 The locking portion 230 is shown in the figure as being located at the end of the rack gear portion 210 at the third pinion member, but the present invention is not limited thereto and the locking portion 230 may be located at a position where the helical teeth of the rack gear portion 210 are not separated from the helical teeth of the pinion member.

[0099] Next, according to the fifth embodiment of the portable self-generating device according to the present invention, Fig.10 and Fig.11 In the fifth embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and repeated description thereof will be omitted.

[0100] Fig.10 1 is a diagram for explaining the matching relationship between the pinion component, the rotating component and the power generation component in the portable self-generating device according to the fifth embodiment of the present invention. Fig.11 It is an exploded perspective view of a portable self-generating device according to a fifth embodiment of the present invention.

[0101] like Fig.10 and Fig.11 As shown, the portable self-generating device according to the fifth embodiment of the present invention further comprises: a rotating component 400, which is respectively provided on the plurality of pinion components 300 and rotates with the forward rotation or reverse rotation of each pinion component; and a power generating component 500, which generates electricity by the rotation of the rotating component 400. The rotating component 400 can also be made of metal or formed of engineering plastic, i.e., polycarbonate.

[0102] In addition, if Fig.11 As shown, in the portable self-generating device according to the fifth embodiment of the present invention, the pinion component 300 is disc-shaped, and a gear portion 310 equivalent to the gear teeth is provided on the circumferential portion of the disc, and a plurality of protrusions 320 are provided on both sides of the disc, and a through hole 301 is provided in the central portion through which the shaft 330 passes in a rotatable manner.

[0103] The rotating member 400 is composed of a first rotating member and a second rotating member respectively engaged with the left and right sides or the top and bottom of the pinion member. The first rotating member can rotate in the counterclockwise direction, and the second rotating member can rotate in the clockwise direction.

[0104] like Fig.10 and Fig.11As shown, the first rotating component includes: a first lock plate 410, which is installed on one side of the pinion component; a first flywheel 430, which has a first clutch gear 431 inside and rotates the power generation component 500 in one direction with the reverse rotation (counterclockwise rotation) of the pinion component; and a first lock component 420, which is installed on the first lock plate 410 and rotates the first flywheel 430. The second rotating component includes: a second lock plate 410', which is installed on the other side of the pinion component; a second flywheel 430', which has a second clutch gear 431' inside and rotates the power generation component in one direction with the positive rotation (clockwise rotation) of the pinion component; and a second lock component 420', which is installed on the second lock plate 410' and rotates the second flywheel 430'. As shown Fig.11 As shown, the first locking component 420 and the second locking component 420' are configured to face opposite directions to each other so that the first rotating component and the second rotating component rotate with the positive rotation and reverse rotation of the pinion component 300 respectively, and the gear directions of the first clutch gear 431 and the second clutch gear 431' are also set to be opposite to each other.

[0105] like Fig.11 As shown, the first and second locking plates 410, 410' are formed of a substantially elliptical flat plate, and a plurality of holes 411 are provided at the peripheral portion of the flat plate corresponding to the plurality of protrusions 320, into which the plurality of protrusions 320 are engaged, and an insertion port 412 is provided at the central portion through which the shaft 330 passes. In addition, a support protrusion is provided around the insertion port 412 to support the rotation of the locking member 420 in a cylindrical protrusion, and a pair of protrusions 413 are provided around the support protrusion to engage with the locking member 420. The pair of protrusions 413 each have a height difference and are formed in two stages. In addition, although Fig.11 The figure shows a structure in which four protrusions 320 and four holes 411 are provided at approximately 90-degree intervals, but the present invention is not limited thereto, and two or three protrusions 320 and four holes 411 may be provided as long as the locking plate 410 can be fixed to the pinion member.

[0106] like Fig.11 As shown, the first and second locking members 420, 420' are formed into a pair, and include: a claw portion 421 meshing with the respective gear teeth of the first clutch gear 431 and the second clutch gear 431'; a hole 423 into which the pair of protrusions 413 are respectively engaged; and an arc portion 422 formed into a semicircular arc shape corresponding to the cylindrical support protrusion. The hole 423 is formed into two stages inside corresponding to the protrusion 413 formed into two stages, thereby firmly maintaining the engaged state of the locking plate 410 and the locking member 420. Fig.11As shown, the claw portion 421 is formed to have a height difference so as to transmit sufficient rotational force to the first clutch gear 431 and the second clutch gear 431 ′.

[0107] like Fig.11 As shown, the first flywheel 430 and the second flywheel 430' are in the shape of a disk 432, and a hole 433 for inserting the shaft 330 is provided at the center of the disk 432. In addition, a space portion is formed on the inner side of each of the first flywheel 430 and the second flywheel 430', and a first clutch gear 431 and a second clutch gear 431' consisting of, for example, 8 gear teeth are provided in the space portion from the central portion toward the peripheral portion. Each gear tooth is formed to be inclined in one direction, for example, to be formed in a shape protruding at an angle of 60 to 80 degrees. On the other hand, as Fig.11 As shown, the gear directions of the first clutch gear 431 and the second clutch gear 431' are opposite to each other. That is, the gear direction of the first clutch gear 431 is set to be able to rotate in the counterclockwise direction, and the gear direction of the second clutch gear 431' is set to be able to rotate in the clockwise direction.

[0108] In addition, a gear ring 434 is provided on the outer periphery of the space portion. Fig.10 As can be seen from the figure, the diameters of the first flywheel 430 and the second flywheel 430' are slightly larger than the diameter of the pinion member 300. Therefore, when the power generation member 500 rotates with the rotation of the first flywheel 430 and the second flywheel 430', the pinion member 300 can be prevented from contacting the power generation member 500.

[0109] On the other hand, for the sake of convenience, Fig.10 Although the locking member and the locking plate are shown in a state of being matched outside the flywheel, the locking member and the locking plate are arranged in the internal space portion of the flywheel.

[0110] The shaft 330 is formed of, for example, stainless steel, such as Fig.11 As shown, a pair of annular grooves 331 are provided on the entire circumference of the shaft 330 , and the pinion gear component is located between the pair of annular grooves 331 . By respectively embedding E-shaped rings 332 in the pair of annular grooves 331 , the pinion gear component can be prevented from shifting during rotation.

[0111] As described above, in the portable self-generating device according to the present invention, Fig.10 As shown, the locking plate and the locking member are engaged with the pinion member, and the locking plate and the locking member are disposed in the inner space of the flywheel, so that the portable self-generating device can be miniaturized.

[0112] like Fig.10As shown, the power generation component 500 includes a gear portion 510 meshing with the rotating component 400, a motor 520, a rotating shaft 530 transmitting the rotational force of the gear portion 510 to the motor 520, and a motor bracket for mounting the motor 520 on the body 100. The gear portion 510 meshes with a ring gear 434 provided on the outer periphery of the first flywheel 430 and the second flywheel 430', and the gear portion 510 rotates with the rotation of the first flywheel 430 and the second flywheel 430', thereby performing power generation in the motor 520. Although the gear ratio of the ring gear 434 and the gear portion 510 meshing with each other is not particularly limited, it is preferably set to have a value as large as possible in order to facilitate power generation.

[0113] On the other hand, in the portable self-generating device according to the present invention, an idle gear 600 is meshed between the first flywheel 430 and the gear unit 510 to allow the gear unit 510 to rotate in one direction. That is, the rotational force of the first flywheel 430 is transmitted to the gear unit 510 through the idle gear 600. The idle gear 600 is rotatably held in the body 100 by a shaft. Fig.10 As shown, since the idler gear 600 is disposed at the lower portion of the first flywheel 430, the outer diameter of the first flywheel 430 is configured to be smaller than the outer diameter of the second flywheel 430'.

[0114] Next, the cooperation relationship among the rack and gear member 200 , the pinion member 300 , and the rotating member 400 will be described.

[0115] Regarding the assembly of the portable self-generating device according to the present invention, first, the shaft 330 is inserted into the pinion component 300, and the flywheel support body is embedded in the flywheel body, and E-rings 332 are respectively embedded in a pair of annular grooves 331, thereby preventing the pinion component from shifting during rotation.

[0116] Then, the shaft 330 is inserted through the insertion openings 412 of the first and second locking plates 410 , 410 ′, and the plurality of holes 411 of the first and second locking plates 410 , 410 ′ are engaged with the plurality of protrusions 320 provided on both sides of the pinion member 300 .

[0117] Next, the holes 423 of the first and second locking members 420 and 420 ′ provided as a pair are fitted into the pair of protrusions 413 provided on the first and second locking plates 410 and 410 ′, respectively.

[0118] Then, the holes 433 of the first flywheel 430 and the second flywheel 430 ′ are inserted into the shaft 330 , and the first and second locking members 420 , 420 ′ are aligned so that they are located at the first clutch gear 431 and the second clutch gear 431 ′.

[0119] Thereafter, the gear portion 510 is meshed with the idler gear 600 through the ring gear 434 of the first flywheel 430 and the ring gear of the second flywheel 430′, and the rack gear portion 210 is located on the upper portion of the pinion member 300, thereby completing the operation as shown in FIG. Fig.10 The self-generating device according to the present invention is shown.

[0120] Next, the pinion member 300 and the rotating member 400 and the rotation of the power generation member 500 following the linear reciprocating motion of the rack gear member 200 are controlled according to Figure 4 and Fig.10 Provide explanation.

[0121] like Fig.10 As shown, in the portable self-generating device according to the present invention, the first clutch gear 431 and the second clutch gear 431′ of the first flywheel 430 and the second flywheel 430′ are respectively kept in a state of meshing with the locking member 420. That is, the angled portion of the claw portion 421 of the locking member 420 is kept in a state of meshing with the respective gear teeth of the first clutch gear 431 and the second clutch gear 431′ formed obliquely in one direction, and the ring gear 434 of the first flywheel 430 and the second flywheel 430′ is kept in a state of meshing with the gear portion 510.

[0122] For example, if the user Figure 4 When the handle portion 220 is pulled as shown in (a) of FIG. 1 , the rack gear portion 210 is pulled out of the body 100 , and thereby each of the plurality of pinion gear members 300 rotates in the clockwise direction.

[0123] Therefore, the first and second locking plates 410, 410' and the first and second locking members 420, 420' engaged with the pinion member 300 are rotated in the clockwise direction.

[0124] That is, if the first and second locking members 420, 420' rotate in the clockwise direction, the claw 421 of the first locking member 420 is in a state of being disengaged from the respective gear teeth of the first clutch gear 431, so that the first flywheel 430 does not rotate, and the second clutch gear 431' engaged with the claw 421 of the second locking member 420' rotates in the clockwise direction. Therefore, if the user pulls the handle portion 220 to pull out the rack gear portion 210 from the body 100, the second flywheel 430' according to the present invention rotates only in one direction, for example, in the figure Fig.10 In the state, it only rotates in the clockwise direction, and the gear part 510 rotates in the counterclockwise direction.

[0125] In addition, if Figure 4As shown in (b), the rack gear part 210 is inserted into the body 100 by pushing the handle part 220, thereby each of the plurality of pinion gear parts 300 rotates in the counterclockwise direction.

[0126] That is, if the first and second locking members 420, 420' rotate in the counterclockwise direction, the claw 421 of the second locking member 420' is in a state of being disengaged from the respective gear teeth of the second clutch gear 431', so that the second flywheel 430' does not rotate, and the first clutch gear 431 engaged with the claw 421 of the first locking member 420 rotates in the counterclockwise direction. Therefore, if the user pushes the handle portion 220 to insert the rack gear portion 210 into the body 100, the first flywheel 430 according to the present invention rotates only in one direction, for example, in the figure Fig.10 In the state, it only rotates in the counterclockwise direction, and the idler gear 600 rotates in the clockwise direction, and the gear part 510 rotates in the counterclockwise direction.

[0127] As described above, in the portable self-generating device according to the fifth embodiment of the present invention, the first flywheel 430 rotates in the counterclockwise direction along with the reciprocating motion of the rack gear component 200. Even if the second flywheel 430′ rotates in the clockwise direction, the gear portion 510 provided in the power generating component 500 continuously rotates in only one direction, i.e., only in the counterclockwise direction, thereby enabling continuous power generation.

[0128] Sixth Embodiment

[0129] Next, according to the sixth embodiment of the portable self-generating device according to the present invention, Fig.12 In the sixth embodiment, the same reference numerals are used for the same parts as those in the fifth embodiment, and repeated description thereof will be omitted.

[0130] Fig.12 1 is a diagram showing a state of a ring gear of a first flywheel in a portable self-generating device according to a sixth embodiment of the present invention.

[0131] In the fifth embodiment, the first flywheel 430 does not rotate when the claw 421 of the first locking member 420 is disengaged from the respective gear teeth of the first clutch gear 431, but the second clutch gear 431' of the second flywheel 430' meshing with the claw 421 of the second locking member 420' rotates in the clockwise direction. However, compared with the fifth embodiment, in the sixth embodiment, the ring gear 434 is provided only at 1 / 2 of the first clutch gear 431 to prevent the first flywheel 430 from rotating due to the idler gear 600 when the second flywheel 430' rotates.

[0132] Therefore, the gear portion 510 rotates in the counterclockwise direction as the second flywheel 430' rotates in the clockwise direction to generate electricity, and the idler gear 600 rotates in the clockwise direction as the gear portion 510 rotates. The clockwise rotational force of the idler gear 600 is transmitted to the first flywheel 430. However, the first flywheel 430 rotates in the counterclockwise direction. In this way, the rotational force transmitted to the first flywheel 430 is transmitted to the portion where the ring gear 434 is not provided, and therefore, the first flywheel 430 does not rotate.

[0133] In addition, the rack gear part 210 is inserted into the body 100 by pushing the handle part 220, thereby, each of the plurality of pinion gear parts 300 rotates in the counterclockwise direction. That is, if the first and second locking parts 420, 420' rotate in the counterclockwise direction, the claw part 421 of the second locking part 420' is in a state of being disengaged from the respective gear teeth of the second clutch gear 431', so that the second flywheel 430' does not rotate, and the first clutch gear 431 meshing with the claw part 421 of the first locking part 420 rotates in the counterclockwise direction, thereby, the rotational force of the ring gear 434 provided on the first flywheel 430 is transmitted to the idle gear 600, so that the idle gear 600 rotates in the clockwise direction, and the gear part 510 rotates in the counterclockwise direction.

[0134] Embodiment 7

[0135] Next, according to the seventh embodiment of the portable self-generating device according to the present invention, Fig.13 In the seventh embodiment, the same reference numerals are used for the same parts as those in the first to fourth embodiments, and repeated description thereof will be omitted.

[0136] Fig.13 1 is a diagram showing the arrangement of a rack and gear member and a plurality of pinion members according to a seventh embodiment of the present invention.

[0137] The above-mentioned first to fourth embodiments show a structure in which multiple pinion components 300 are arranged in a row in the main body 100 and the multiple pinion components 300 rotate forward and reverse with the linear reciprocating motion of the rack gear component 200, but in the seventh embodiment, the multiple pinion components 300 are arranged in multiple rows.

[0138] In addition, if Fig.13 As shown, the rack gear member 200 is structured as follows: a pair of rack gear parts 210 are provided in the up-down direction, and a plurality of pinion gear members 300 are respectively matched to the upper and lower parts of the pair of rack gear parts 210 .

[0139] Therefore, when the rack gear portion 210 is pulled out from the main body 100, the multiple pinion components 300 arranged at the upper portion rotate in the counterclockwise direction to generate electricity, and the multiple pinion components 300 arranged at the lower portion rotate in the clockwise direction to generate electricity. When the rack gear portion 210 is inserted into the main body 100, the multiple pinion components 300 arranged at the upper portion rotate in the clockwise direction to generate electricity, and the multiple pinion components 300 arranged at the lower portion rotate in the counterclockwise direction to generate electricity.

[0140] Compared with the portable self-generating devices shown in the first to fourth embodiments, the seventh embodiment having the above-described structure can further improve the power generation efficiency.

[0141] In addition, although the above description shows a structure in which the rack gear parts 210 are arranged in a pair in the up and down directions and each of the pair of rack gear parts is equipped with multiple pinion gear parts 300, it is not limited to this, and it is also possible to apply a structure in which a pair of rack gear parts are arranged in the left and right directions and each of the pair of rack gear parts is equipped with multiple pinion gear parts 300.

[0142] In addition, although the Fig.13 In the structure of the embodiment, the first opening 110 is provided in the main body 100, but the present invention is not limited thereto and can also be applied to the following structure. Figure 7 As shown in the figure, the main body 100 is provided with a first opening 110 and a second opening 130 or as shown in the figure Fig. 9 As shown, the rack and pinion member 200 is provided with a first hinge 222 and a second hinge 225 .

[0143] Embodiment 8

[0144] Next, according to the eighth embodiment of the portable self-generating device according to the present invention, Fig.14 and Fig.15 In the eighth embodiment, the same reference numerals are used for the same parts as those in the first to fourth embodiments, and repeated description thereof will be omitted.

[0145] Fig.14 1 is a plan view showing the arrangement of a rack and gear member and a plurality of pinion members according to an eighth embodiment of the present invention. Fig.15 FIG. 1 is a plan view showing another example of the rack and pinion member according to the eighth embodiment of the present invention.

[0146] In the first embodiment, a plurality of pinion components 300 are arranged in a row in the body 100 and the plurality of pinion components 300 rotate forward and reverse with the linear reciprocating motion of the rack gear component 200. However, in the eighth embodiment, the plurality of pinion components 300 are arranged in a plurality of rows. Fig.14 2 shows a structure in which the plurality of pinion gear members 300 are arranged in two rows, but the present invention is not limited thereto, and three or more rows may be arranged.

[0147] In addition, if Fig.15 As shown in FIG. 1 , a structure in which a slit 270 is provided in a portion of the rack gear portion 210 can also be applied so that the rack gear component 200 operates separately for each row of the plurality of pinion components 300 arranged in two rows. Fig.12 The structure in which the first flywheel 430 and the second flywheel 430 ′ are provided as shown is applied to the rack gear member 200 in which the slit 270 is formed, whereby each pinion gear member 300 can operate in the same manner as the first embodiment.

[0148] Ninth Embodiment

[0149] Next, according to the ninth embodiment of the portable self-generating device according to the present invention, Fig.16 and Fig.17 In the ninth embodiment, the same parts as those in the first to fourth embodiments are denoted by the same reference numerals, and repeated description thereof will be omitted.

[0150] Fig.16 1 is a diagram showing the arrangement of a rack and gear member and a plurality of pinion members according to a ninth embodiment of the present invention. Fig.17 It is shown in Fig.16 A three-dimensional diagram of the appearance of a portable self-generating device.

[0151] Although the seventh and eighth embodiments described above show a structure in which a plurality of pinion members 300 arranged in two rows are operated by one rack gear member 200, in the ninth embodiment, it is also possible to Fig.16 and Fig.17 As shown, it works with two rack and pinion components.

[0152] That is, the rack and gear member 200 can include a first rack and gear member 250 provided corresponding to the plurality of pinion gear members in the first row, and a second rack and gear member 260 provided corresponding to the plurality of pinion gear members in the second row.

[0153] like Fig.16 and Fig.17 As shown, the first rack gear member 250 and the second rack gear member 260 are provided, thereby enabling the user to generate electricity more efficiently using both hands.

[0154] Example 10

[0155] Next, according to the 10th embodiment of the portable self-generating device according to the present invention, Fig.18 In the tenth embodiment, the same reference numerals are used for the same parts as those in the first to fourth embodiments, and repeated description thereof will be omitted.

[0156] Fig.18 10 is a block diagram of a portable self-generating device according to the tenth embodiment of the present invention.

[0157] like Fig.18 As shown in (a) of FIG. 10 , in the tenth embodiment, a rack gear portion 710 as a rack gear member is provided in a structure in which a winding state is maintained in the main body 100 by a rotating unit 700 .

[0158] like Fig.18 As shown in (b), the above-mentioned rotating unit 700 includes: a reel 720, which is installed in the main body 100 in a rotatable manner and maintains a state of being wound with the rack gear part 710, and can rotate by pulling and winding the rack gear part 710; a spiral spring 730, which is made of spring steel and maintains a spring state of being wound, for example, about 8 to 12 turns; and a spring cover part 740, which is embedded in the above-mentioned reel 720 and has the above-mentioned spiral spring 730 built in.

[0159] Although the material of the rack gear part 710 is made of metal material, it is not limited to a specific material as long as it has the function of performing winding and unwinding on the reel 720. One end of the rack gear part 710 can be fixed to the reel 720, and the other end of the rack gear part 710 can be fixed to the reel 720. Fig.18 As shown in (a) of FIG. 7 , the rack and pinion portion 710 is fixed to the handle 750 , and the pulling state of the rack and pinion portion 710 is controlled by the elastic force of the coil spring 730 .

[0160] like Fig.18 As shown in (c) of FIG. 1 , the rack gear portion 710 is provided with a gear groove 711 that meshes with the gear teeth of the pinion member 300 .

[0161] like Fig.18 As shown in (b), the above-mentioned reel 720 is formed into a bobbin shape to keep the rack gear portion 710 in a wound state, and a accommodating portion 721 for a built-in spring cover portion 740 is provided in the central portion of the reel 720, and a plurality of protrusions 722 in which the spring cover portion 740 is embedded are provided on the inner side of the reel 720.

[0162] The coil spring 730 is made of spring steel and is maintained in a spring state of being wound about 8 to 12 turns, for example. The outer end 731 of the coil spring is inserted into the insertion port 742 formed in the spring cover 740, and the inner end 732 of the coil spring 730 is inserted into the spring holder provided in the body 100. The coil spring 730 is maintained in a wound state, and the rack gear part 710 is also maintained in a state of being wound around the reel 720. Therefore, the pulling of the rack gear part 710 by the user is restricted in response to the unwinding condition of the coil spring 730, and the rack gear part 710 is restored to a state of being wound around the reel 720 by the restoring force of the coil spring 730.

[0163] The spring cover 740 is formed into a hollow cylindrical shape to hold the coil spring 730 therein, and a plurality of grooves 741 are formed on the outside of the spring cover 740 corresponding to the plurality of protrusions 722 to be fitted with the plurality of protrusions 722, and an insertion port 742 is provided on the circumference thereof to insert the outer end 731 of the coil spring 730 and a mounting portion 743 is provided to be mounted on the outer end inserted through the insertion port 742. Therefore, the outer end 731 of the coil spring 730 is fitted into the receiving portion 721 of the winding shaft 720 in a state where the outer end 731 of the coil spring 730 is mounted on the mounting portion 743 through the insertion port 742, thereby preventing the outer end 731 of the coil spring 730 from being separated from the spring cover 740.

[0164] Therefore, in the tenth embodiment, Fig.18 In the state (a), if the user pulls the handle 750, the gear groove 711 engages with the gear teeth of the pinion component 300, causing each pinion component to rotate in the clockwise direction to generate electricity. If the user stops pulling the handle 750, the restoring force of the disc spring 730 causes the pinion component to rotate in the counterclockwise direction, thereby enabling continuous power generation.

[0165] Example 11

[0166] Next, an eleventh embodiment of the portable self-generating device according to the present invention will be described.

[0167] Although the portable self-generating device of the fifth embodiment is described as a structure in which the motor 520 is rotated by the rotation of the gear portion 510, the stator and the rotor can be applied to the eleventh embodiment.

[0168] That is, the technology disclosed in the above-mentioned Patent Document 2 can be applied to each pinion component 300 applicable to the present invention as a rotating component. A stator is provided on the inner circumferential surface of the pinion component 300 according to the present invention, and a rotor is provided in a manner inserted into the pinion component 300 and separated from the stator. In addition, a first rotating unit is provided to rotate the rotor in one direction by utilizing the rotational force of the pinion component 300 generated when the rack gear component 200 moves linearly in one direction, and a second rotating unit is provided to rotate the rotor in the above-mentioned one direction by utilizing the reverse rotational force of the pinion component 300 generated when the rack gear component 200 moves linearly in another direction, thereby providing a structure that allows a plurality of pinion components 300 to operate simultaneously.

[0169] The use example of the portable self-generating device constructed as described above is as follows Fig.19 Provide explanation.

[0170] Fig.19 This is a diagram showing an example of a usage state of the portable self-power generating device of the present invention.

[0171] like Fig.19 As shown, the user stands the body 100 upright and supports the pair of support parts 120 with his feet and makes the rack gear member 200 linearly reciprocate in the vertical direction, thereby the plurality of pinion members 300 repeatedly rotate forward and reverse to rotate the gear part 510, thereby continuously generating electricity.

[0172] The electricity generated by the power generation component 500 is charged in a battery (not shown) disposed in the main body.
