Description

  The present invention relates to an information device that operates based on electric energy obtained by generating power by manpower operation and charging the output of the power generation.

  2. Description of the Related Art Conventionally, a configuration of an information device that manually generates power and operates with electric energy charged based on the power generation has been proposed.

  However, in any of these information devices, after winding the mainspring, the gear rotates based on the elastic force of the mainspring, and as a result, power is generated by the DC generator.

  The winding of the mainspring requires manual rotation or lever operation, but such operation is relatively complicated. On the other hand, in the case of a DC generator, it is necessarily the same as in the case of a DC motor. Since the presence of a brush (brush) is indispensable, the disadvantage of failure is unavoidable.

  The applicant has so far made a configuration of a mobile phone in which one end of a string is connected to an information device through a winder or a slit or a pole, and the other end is connected to an attachment device that can be attached to a pocket. Although it has been proposed (1999 Patent Application No. 115980, 1999 Patent Application No. 145290), in these configurations, at least one of the hands holding the string and the information device is linearly moved. By this, it is possible to realize the relative movement between the string and the information device.

  However, the basic configuration of performing the power generation by moving the hand linearly based on the assumption that such a string has been adopted and operating the information device using the output from the power generation as a power source is proposed. It has not been.

  The present invention realizes power generation based on the rotational movement or movement of a permanent magnet through a winder or slit or pole that is engaged with a string, and then operates an information device using the output of the power generation as a power source. It is an object to provide a basic configuration that can be used.

In order to solve the above-mentioned problems, the basic configuration of the present invention is provided in a predetermined case, and a slide piece that can be slid by a slide piece fixed to a string, or a rod-shaped pole, along the slit or the pole. A linear type AC that is linked to the movement of the slide piece by slide and has both poles (N pole and S pole) along the moving direction, and a power generation coil around the moving area of the permanent magnet. It comprises an information device that can be operated on the basis of the power source of the storage battery, with a generator and a storage battery that charges the output of the AC generator via a rectifier.

  Based on the basic configuration, the user simply generates a power by holding both the string and the information device with both hands and moving both or both hands in a straight line, and is charged by the power generation. The information device can be operated based on the power source.

  Furthermore, since the permanent magnet is employed in the basic configuration, the AC generator can be configured simply.

  In order to charge the storage battery 52, which is the power source of the information device 6, the output from the power generation is preferably DC rather than AC.

In the basic configuration, as shown in FIG. 1, a slit provided in a predetermined case 23 or a slide piece 11 that slides on a pole 22 is fixed to the string 1 and then reciprocated as the string 1 reciprocates. The coil 41 provided around the moving area of the permanent magnet 42 is caused to perform electromagnetic induction based on the reciprocating motion of the permanent magnet 42 interlocked with the slide piece 11. Based on the fact that the motion in a predetermined direction and the generation of current are reversed with respect to the linear motor, so-called linear power generation is performed (FIG. 1A shows the case where the slit 22 is employed, and FIG. (B) has shown the case where the pole 22 is employ | adopted.).

In the linear type power generation, AC power generation is inevitably produced by reversing the moving direction of the slide piece 11 and the permanent magnet 42 along with the reciprocating motion.
In the linear type power generation, there may be a configuration in which an electromagnet is used on the side that reciprocates in conjunction with the slide piece 11, but in that case, a portion that inevitably transmits current along with movement similar to a pantograph. Since the structure is complicated, the moving element is the permanent magnet 42 in the basic structure.

As described above, in the basic configuration, since the AC voltage is generated, the storage battery 52 is charged via the rectifier 51. As the rectifier 51, a half-wave rectifier and a full-wave rectifier are used. Either can be used.
However, if energy efficiency is taken into consideration, a full-wave rectifier is preferable.
In FIG. 1, two lines connecting the rotary AC generator 31 or the linear AC generator 32, the rectifier 51, the storage battery 52, and the socket 53 indicate current connection lines.

  In order to operate the information device 6, a predetermined voltage is required (in the case of a mobile phone, usually about 1.5 to 2.5 volts is required), but the storage battery 52 is supplied with the predetermined voltage. In order to charge, the DC voltage inevitably generated through the rectifier 51 needs to have a voltage value exceeding the predetermined voltage even if the voltage value itself fluctuates.

  Therefore, also in the basic configuration, the degree of the magnetic field of the permanent magnet 42 and the number of windings of the coil 41 positioned around the permanent magnet 42 are set so that the peak value of the generated voltage by the AC generator exceeds the predetermined voltage. Although it is required to design, if the peak value generated by the power generation of the AC generator is equal to or lower than the predetermined voltage, a DC-DC converter is inserted between the rectifier 51 and the storage battery 52. Thus, it is preferable to adjust so that the peak value reaches the predetermined voltage or more.

In the basic configuration, it is not always necessary to interpose an urging force by elastic force so that the string 1 is sucked into the winder and wound around the winder 21 .

Similarly, in the basic configuration, the number of permanent magnets 42 that reciprocate is not limited to one as shown in FIG. 2A, but two or more as shown in FIG. 2B. It is also possible to adopt a configuration in which they are juxtaposed with each other and connected on a straight line.

A configuration in which the power generator 9 and the information device 6 by the AC generator, the rectifier 51, and the charger are integrated with the information device 6 is also possible. However, as shown in FIG. It is also possible to adopt a configuration in which it is detachable via the connector.
However, in the basic configuration, if it is considered that the slit 23 or the pole 22 is received in the predetermined case 23, the integrated configuration as described above includes one case 23 and the information on the power generation portion 9. It becomes possible to share with the device 6, and the range of the slit or pole 22, and consequently the moving area of the slide piece 11 and the permanent magnet 42 can be set widely.

In order to synchronize the movement of the slide piece 11 and the movement of the permanent magnet 42 , a special design device is required.

In case of FIG. 3 (a) is a slide piece 11 and the permanent magnet 42 connected by rods 8 which is extended in the direction of movement, the rod 71 is moved inside the coil 41 together with the permanent magnets 42, In this case, since the area | region of the slide piece 11 has the area | region where the string 1 slides and the movement area | region of a magnet and the movement area | region of a magnet are in series, both movement area | regions are provided along the whole longitudinal direction of an apparatus. It must be impossible (they will move along a region within 1/2 of the longitudinal direction).

In contrast, as shown in FIG. 3B, one end of the permanent magnet 42 is connected to an elastic spring, and the belt is supported by a pulley 72 positioned in the opposite direction with the elastic spring and the coil 41 interposed therebetween. Alternatively, when the permanent magnet 42 is moved toward the pulley 72 by connecting another slit 10 or slit or pole 22 to the slide piece 11, the slide piece resists the elastic force of the elastic spring 18. 11 is slid and the magnet is moved toward the elastic spring 18, it is moved by the urging force of the elastic spring 18. In such a configuration, the slide region of the slide piece 11 is moved. because a moving region of the permanent magnets 42 are in parallel state, it is possible to provide along the entire length of the device slides region, to move the moving region of the device effectively The ability.

  In the embodiment, as shown in FIG. 4, an attachment device 12 that can be attached to a pocket is attached to the tip of the string 1.

  In such an embodiment, it is possible to use the information device 6 with the attachment device 12 attached to a pocket or the like, and even if the information device 6 is separated from the body by an accident, It can prevent falling.

  Furthermore, after the other end portion of the string 1 is fixed in a pocket or the like, the power generation portion 9 (however, as described above, when it is integrated with the information device 6 and is detachable) It is also possible to generate power by moving in a predetermined direction.

  The present invention can be used in the industrial technical field relating to various devices and equipment that can be operated by a power source based on simple manual power generation.

The basic structure is shown, (a) shows the case of a slit, and (b) shows the case of a pole. The arrangement | positioning state of a coil and a permanent magnet is shown, (a) has shown the case where one permanent magnet is employ | adopted, (b) has shown the case where two permanent magnets are employ | adopted. The arrangement relationship between the slide piece, the coil, and the permanent magnet is shown. (A) shows the state where the moving area of the slide piece and the moving area of the permanent magnet are arranged in series. (B) shows the slide piece. The state where the area | region of a piece and the movement area | region of a permanent magnet are arrange | positioned in parallel is shown. It is a sketch which shows the state of the Example which uses a clasp.
