JP 2000-175720 A (FIG. 4)

  By the way, when charging the battery of the portable terminal using the power generated by the generator by rotating the handle, the user must intentionally rotate the handle to generate power, It is necessary to perform a very troublesome work that is troublesome.

  On the other hand, when the battery of a portable terminal is charged by a solar cell, no special work is required for the user. For example, in a place with low light such as at night or indoors, Is not performed or the amount of power generation becomes very small, so that the battery of the portable terminal cannot be fully charged. Also, when a solar cell is attached to the outer surface of the case body that accommodates the mobile terminal, it is necessary to make the area of the solar cell as large as possible in order to secure the amount of power generation. Therefore, for example, a solar cell is provided. It is not desirable to provide the case with an opening or the like that cannot be formed. For this reason, for example, when the portable terminal is accommodated in the case body, in order to operate the portable terminal, the portable terminal must be taken out of the case, which is very complicated. Of course, it is conceivable to provide a lid for enabling the portable terminal to be operated with the portable terminal housed in the case body, and to provide a solar cell on the outer surface of the lid. Even in such a case, an operation such as opening the lid portion is necessary, and there is a problem that is unsuitable for dealing with wrinkles such as when receiving an incoming call to a mobile phone terminal.

  In addition, when a battery of a portable terminal is charged by a movement type generator, the movement used for a self-powered wristwatch or the like that has been conventionally known as a configuration of the movement has a very large amount of power that can be generated. In other words, it is insufficient for charging a battery of a portable terminal such as a portable telephone terminal.

  The present invention has been proposed in view of such circumstances, and can generate power necessary for charging a battery of a mobile terminal such as a mobile phone terminal. Provided are a power generation device and a portable terminal holder that do not require a user to perform special work for charging, and can use a portable terminal immediately even while charging a battery. For the purpose.

  The power generation device of the present invention includes a power generation unit that converts rotational motion into electric power, a motion conversion unit that converts telescopic motion into rotational motion, and transmission that transmits the rotational motion converted from the telescopic motion by the motion conversion unit to the power generation unit. And a connection part that is at least electrically connectable to a connection terminal of a predetermined portable terminal equipped with a rechargeable battery, and the power generated by the power generation part is transmitted through the connection part to the predetermined terminal. By supplying the portable terminal, the above-described problems are solved.

  The portable terminal holder of the present invention transmits to the power generation unit a power generation unit that converts rotational motion into electric power, a motion conversion unit that converts telescopic motion into rotational motion, and a rotary motion converted from the telescopic motion by the motion conversion unit. The transmission unit and a connection terminal of a predetermined portable terminal provided with a rechargeable battery have a connection unit that can be at least electrically connected, and the power generated by the power generation unit is predetermined via the connection unit. The power generation device section to be supplied to the mobile terminal and the connection portion of the power generation device section are housed inside, and the connection terminal of the predetermined mobile terminal and the connection portion are connected to each other. By having a terminal holding portion that holds at least a part of the body, the above-described problems are solved.

  That is, according to the present invention, for example, it is possible to convert a telescopic motion according to a vertical vibration motion when the user of the mobile terminal walks into a rotational motion, and further convert the rotational motion into electric power. It is designed to generate electricity.

  Further, according to the present invention, the mobile terminal is supplied with electric power from the power generation device in a state where at least a part of the casing is held by the terminal holding unit.

  According to the present invention, for example, a telescopic motion corresponding to a vertical vibration motion when a user of a mobile terminal walks is converted into a rotational motion, and the rotational motion is converted into electric power to generate power. Therefore, for example, power required for charging the battery of the mobile terminal can be generated without requiring a user to perform a special operation to charge the battery of the mobile terminal such as a mobile phone terminal. .

  In addition, according to the present invention, since power is supplied from the power generation device in a state where only at least a part of the casing of the mobile terminal is held by the terminal holding unit, charging the battery of the mobile terminal Even within, the user can use the terminal immediately.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  In the present embodiment, as an example of the power generation device and the mobile terminal holder of the present invention, a mobile terminal holder having a function of holding a mobile phone terminal and charging a battery of the mobile phone terminal is described. However, the present invention is not limited to this example. It is needless to say that the present invention is not limited to this example. For example, the holder for various portable terminals driven by a rechargeable battery such as PDA (Personal Digital Assistants) is used. Is also applicable.

[Schematic configuration of portable terminal holder]
In FIG. 1, schematic structure of the portable terminal holder 1 of embodiment of this invention is shown. In addition, in order to show the structure of the portable terminal holder 1 of this embodiment in an easy-to-understand manner, FIG. 1 shows the main components inside the holder housing in a state where the housing is transparent.

  The portable terminal holder 1 of the present embodiment accommodates, for example, a hook portion 10 for attaching to a user's belt, bag, clothes, etc., at least a generator 20, a rotating ring 16, a spring spring 17, and a gear 19. The main body portion 12 and one end portion are fixed to the hook portion 10 and the other end portion is fixed to the outer peripheral portion of the rotating ring 16 of the main body portion 12 and wound around the outer peripheral portion of the rotating ring 16. The cable 15 and the IO connector 14 that are electrically connected to the generator 20 in the main body 12 are configured.

  Furthermore, the portable terminal holder 1 of the present embodiment has a bellows cylinder portion 11. The bellows tube portion 11 has, for example, a cylindrical and expandable / contractible bellows structure, and one end portion in the expansion / contraction direction of the bellows structure is an outer wall surface portion of the hook portion 10 (one end of the cable 15 is fixed). And the other end in the expansion / contraction direction is fixed to the outer wall surface of the main body 12 (the outer wall surface on the side where the other end of the cable 15 is fixed). ing. The cable 15 that connects the hook portion 10 and the main body portion 12 is disposed in the cavity of the bellows tube portion 11.

  The length when the bellows tube portion 11 is extended is at least shorter than the cable length when the cable 15 is pulled out from the rotating ring 16, and the bellows before the cable 15 is completely pulled out from the rotating ring 16. The cylinder part 11 is made to extend. Thereby, when the cable 15 is completely pulled out from the rotating ring 16, for example, an impact applied to the cable 15 (and also an impact applied to the main body 12) can be reduced. Moreover, in this embodiment, since the cable 15 is accommodated in the bellows tube portion 11, the cable 15 is protected, and at the same time, for example, the user directly touches the cable 15 to be injured. It is possible to prevent.

  Moreover, the said IO connector part 14 of the portable terminal holder 1 of this embodiment is the outer wall surface part to which the said other end part of the said bellows cylinder part 11 is being fixed among each surface part which comprises the main-body part 12, for example. It is provided so as to protrude outward from the corresponding opposite wall surface. The IO connector portion 14 has a shape that fits with the connector of the mobile phone terminal, and can be electrically connected to the connector of the mobile phone terminal when joined to the connector of the mobile phone terminal. When the IO connector 14 is electrically connected to the connector of the mobile phone terminal and power is generated by the generator 20 of the main body 12, the generated power from the generator 20 is It can be supplied to the mobile phone terminal side. The IO connector unit 14 is connected only to the connector of the mobile phone terminal so that the connectors are not easily disconnected and only when a predetermined opening operation is performed by the user. Claw portions 14a and 14b for enabling the connector to be released are also provided.

  Moreover, the portable terminal holder 1 of this embodiment also has the terminal holding | maintenance part 13 fixed to the wall surface part in which the said IO connector part 14 of the said main-body part 12 is provided. As shown in FIGS. 2 and 3, the terminal holding unit 13 has an opening 13 a having a shape into which the terminal housing end 51 on the connector side of the mobile phone terminal 50 can be inserted, and from the opening 13 a side. At the bottom of the terminal holding part 13 that can be seen, the IO connector part 14 of the main body part 12 is arranged so as to protrude through the wall surface of the terminal holding part 13.

  When the terminal housing end 51 of the mobile phone terminal 50 is inserted through the opening 13a and the connector of the mobile phone terminal 50 is joined to the IO connector portion 14, the terminal holding portion 13 The mobile phone terminal 50 is held so as to cover at least a part of the mobile phone terminal 50 on the terminal housing end 51 side.

  That is, the terminal holding unit 13 is connected to the IO connector unit 14 and the mobile phone terminal 50 by a user's movement, for example, when the IO connector unit 14 of the main body unit 12 and the connector of the mobile phone terminal 50 are joined. The connector has at least a function of preventing the connectors from being disconnected or the connectors from being damaged by the force applied to the joint with the connector.

[Internal structure of main body and operation of portable terminal holder]
In the main body portion 12 of the portable terminal holder 1 of the present embodiment, the rotating ring 16 is rotatable around a shaft 18 fixed to the housing or the like of the main body portion 12. The mainspring 17 is disposed on the inner side.

  The spring spring 17 has a structure in which the spring end of the innermost peripheral portion is fixed to the shaft 18 and a plate-like spring is wound around the shaft 18 substantially at the center. The end is fixed at a predetermined position on the inner periphery of the rotating ring 16.

  Therefore, when a rotational force is applied to the rotating ring 16 in the direction in which the mainspring 17 is wound, the mainspring spring 17 has a restoring force corresponding to the winding force corresponding to the rotational force (wound. Sometimes it stores the restoring force to return it to its original state (hereinafter referred to as spring repulsion).

  Then, a rotational force is applied to the rotary ring 16 in the direction in which the mainspring 17 is wound, and a certain amount of spring repulsive force is stored in the mainspring spring 17, and then the rotational force applied to the rotary ring 16 is released. As a result, the spring repulsive force stored in the mainspring 17 is released, whereby the rotating ring 16 rotates in a direction opposite to the rotating direction when the mainspring 17 is wound.

  In the portable terminal holder 1 of the present embodiment, the end of the cable 15 is fixed to the outer peripheral portion of the rotating ring 16 as described above. For example, the cable 15 is wound around the outer periphery of the rotating ring 16 most when the winding amount of the spring 17 is the smallest (when the spring repulsive force is the smallest). In other words, for example, as shown in FIG. 1, when the hook portion 10 is closest to the main body portion 12, the cable 15 is wound most around the outer periphery of the rotating ring 16. The mainspring 17 is in a state where the winding amount (spring repulsive force) is the smallest.

  For these reasons, for example, as shown by an arrow E in FIG. 2, when the cable 15 is pulled by applying a force that moves in a direction in which the main body 12 is pulled away from the hook 10, the rotating ring 16 is The cable 15 rotates in the direction opposite to the winding direction of the cable 15 (that is, the direction in which the wound cable 15 is pulled out) (for example, rotates in the direction of the arrow R2 in FIG. 2). In 17, the amount of winding is increased and the spring repulsive force is accumulated.

  On the other hand, when the spring repulsive force is stored in the mainspring spring 17 and then the force applied in the direction in which the main body 12 is pulled away from the hook portion 10 is released, the spring repulsive force stored in the mainspring spring 17 is released. Thus, the rotating ring 16 rotates in the direction indicated by the arrow R3 in FIG. 3 (the direction opposite to the arrow R1 in FIG. 2), and the cable 15 is wound around the rotating ring 17, Accordingly, the main body 12 moves in a direction approaching the hook 10 as indicated by an arrow C in FIG.

  Here, in the present embodiment, for example, when the mobile phone terminal 50 is being held by the terminal holding portion 13 at the same time that the hook portion 10 is attached to the waist belt or the like of the user, for example, the user When a user walks or is in a moving car or train, the user's body vibrates up and down due to the movement of the walking or car, for example, the main body 12 and the terminal. When the weight of the cellular phone terminal 1 held by the holding unit 13 is applied in a direction in which the main body unit 12 is separated from the hook unit 10, the cable 15 is pulled out from the rotary link 16 to wind the spring 17 (see FIG. 2 (in the direction of arrow R1 in FIG. 2), a rotational force is applied to the rotating ring 16, and the spring spring 17 stores a spring repulsive force.

  On the other hand, when the user's body vibrates up and down due to the movement of the above-mentioned walking or automobile, for example, the weight of the mobile phone terminal 1 held in the main body 12 and the terminal holding portion 13 hooks the main body 12. When applied in the direction approaching the portion 10, the force to pull out the cable 15 from the rotary link 16 is released, the repulsive force stored in the mainspring spring 17 is released, and the cable 15 is wound up (arrow in FIG. 3). A rotational force is applied to the rotary ring 16 in the R3 direction).

  That is, according to the portable terminal holder 1 of the present embodiment, the expansion and contraction motion in which the distance between the hook portion 10 and the main body portion 12 changes is converted into the rotational motion of the rotary ring 16 through the cable 15 and the spring spring 17. ing. In this case, the spring characteristics of the mainspring 17 are such that the user walks with respect to the total weight of the main body 12 and the mobile phone terminal 50 when the mobile phone terminal 50 is attached to the terminal holding portion 13. It is desirable to optimize the spring characteristics so that the vibration caused by the above can be converted into a stretching and retracting movement of the cable 15 that is drawn and unwound.

  Further, in the portable terminal holder 1 of the present embodiment, the rotational movement in the direction of arrow R1 in FIG. 2 and the rotational movement in the direction of arrow R3 in FIG. It is transmitted to the rotational motion of the gear 19 etc. as indicated by the arrow R 4 in the middle, and the rotational motion is transmitted to the generator 20. As a result, the generator 20 generates power while the rotating ring 16 is rotating. And in the portable terminal holder 1 of this embodiment, the electric power generated by transmitting the rotational motion of the arrows R1 and R3 to the generator 20 is supplied to the cellular phone terminal 50 via the IO connector unit 14. Thus, the battery of the mobile phone terminal 50 is charged.

  In the present embodiment, the gear ratio obtained from the diameter of the rotating ring 16 and the diameter of the gear 19 is set to a value that allows the generator 20 to generate power efficiently from the rotational motion of the rotating ring 16. Further, in the present invention, the gear 19 is not limited to one, and may be a combination of a plurality of gears. In this case, the gear ratio is set to a value that allows the generator 20 to generate power efficiently. In addition, although the gear 19 is directly connected to the rotating shaft of the generator 20 in the examples of FIGS. 1 to 3, the present invention is not limited thereto.

  In the present embodiment, the shaft 18 is fixed to the main body 12, the rotating ring 16 can be rotated, and the cable 15 can be wound around the outer peripheral portion of the rotating ring 16. In the present invention, the rotating ring 16 is fixed to the main body 12 to enable the shaft 18 to rotate, and the cable 15 is connected to the shaft 18. A configuration in which winding is possible and the rotational motion of the shaft 18 is transmitted to the generator 20 directly or via the gear 19 or the like may be employed. In this example, the end portion of the cable 15 is fixed to the shaft 18, and when the cable 15 is pulled out by applying a force that moves the main body portion 12 in a direction away from the hook portion 10, the shaft 18 is When the spring 15 is rotated and the spring repulsive force is stored in the main spring 17, the cable 15 is moved to the shaft 18 when the spring repulsive force of the main spring 17 is released due to the force that moves the main body 12 in the direction approaching the hook portion 10. It will be wound up.

[Relationship between power generation by main body of mobile terminal holder and charging of mobile phone terminal]
Hereinafter, the relationship between the gear 19 in the main body 12 of the portable terminal holder 1 and the generator 20 and the relationship between battery charging in the cellular phone terminal 50 will be schematically shown using FIG. 4.

  In FIG. 4, when the gear 19 rotates in the main body 12 of the portable terminal holder 1 as described above and the rotational force is transmitted to the generator 20, the generator 20 generates power. The electric power generated by the generator 20 is supplied to the mobile phone terminal 50 via the IO connector.

  In the mobile phone terminal 50, the DC / DC converter 55 boosts or lowers the power supplied from the mobile terminal holder 1 to a specified voltage so that the battery 56 in the terminal can be charged. Then, the power boosted or stepped down to a specified voltage by the DC / DC converter 55 is sent to the battery 56. Thereby, in the mobile phone terminal 50, the battery 56 is charged.

  In addition, although the example of FIG. 4 has shown the case where the generator 20 is a direct current generator, when the generator 20 is an alternating current generator, alternating current is made into direct current in the output stage of the said generator 20. An AC / DC converter for conversion is provided.

[Summary]
As explained above, according to the portable terminal holder 1 of the present embodiment, the hook portion as shown by the arrow E in FIG. 2 or the arrow C in FIG. When the distance between the main body 12 and the main body 12 is converted into a telescopic motion that changes, and the main body 12 is pulled away from the hook 10 as indicated by an arrow E in FIG. When the main body 12 approaches the hook 10 as shown by the arrow C in FIG. 3, the rotating ring 16 rotates in the direction of the arrow R3 in FIG. , R3 is transmitted to the rotational movement of the gear 19 as indicated by the arrow R2 in FIG. 2 or the arrow R4 in FIG. The generated power is supplied to the mobile phone terminal 50 via the IO connector unit 14 and used to charge the battery of the mobile phone terminal 50.

  Thereby, according to the portable terminal holder 1 of this embodiment, the battery of the portable telephone terminal 50 can be always charged while the user walks or rides in an automobile or the like. In the current mobile phone terminal 50 whose power consumption is increasing due to the function, the battery can be held longer.

  That is, according to the mobile terminal holder 1 of the present embodiment, the battery of the mobile phone terminal can be used without performing a cumbersome work for the user himself / herself to intentionally generate power as in the conventional method of rotating the handle. In addition, it is not always necessary to have a bright environment as in the conventional method using a solar cell, and the battery of the mobile phone terminal can be charged in various environments.

  Furthermore, according to the portable terminal holder 1 of the present embodiment, power is generated by a combination of the cable 15 and the spring 17 having a certain length, the rotary ring 16, the gear 19, and the generator 20, Compared with a conventional movement-type generator, more power can be generated with a simple and inexpensive configuration, and a battery with a large capacity such as a mobile phone terminal can be charged.

  Further, according to the mobile terminal holder 1 of the present embodiment, when the mobile phone terminal 50 is held in the terminal holding unit 13 and is in a chargeable state, for example, when there is an incoming call to the mobile phone terminal 50 or the like. However, since the hook portion 10 and the main body portion 12 are connected by the expandable / contractible bellows tube portion 11 and the cable 15 that can be wound and pulled out, the user can immediately hold the mobile phone terminal 50 in her hand. The incoming call can be handled.

  In addition, of course, in the mobile terminal holder 1 of the present embodiment, the battery of the mobile phone terminal 50 is charged even when, for example, the user intentionally separates and brings the hook portion 10 and the main body portion 12 apart. Therefore, it is possible to cope with a case where the battery is not sufficiently charged only by vibration caused by walking or riding by the user.

  The above description of the embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made according to the design or the like as long as the technical idea according to the present invention is not deviated.

  In the above-described embodiment, an example in which the hook portion 10 is attached to a user's belt or the like has been described. However, the hook portion 10 may be attached to an arbitrary place in a car of a car, for example. In this case, more vibrations can be applied to the portable terminal holder 1 of the present embodiment than when the user rides on the automobile with the hook portion 10 attached to the belt or the like of the user. It becomes possible to generate electric power.

  Further, in the above-described embodiment, the configuration in which the IO connector 14 and the connector of the mobile phone terminal 50 are directly connected has been described. However, in addition, for example, separate power supply is provided between the IO connector 14 and the connector of the mobile phone terminal 50. Cable is connected, and the mobile phone terminal 50 is not directly attached to the terminal holding part 13, and in that state, the distance change between the hook part 10 and the main body part 12 is converted into electric power, and the electric power is converted into electric power.
