Description

  The present invention relates to a battery type power supply device and a remote control device used for a remote control device.

  Conventionally, a replaceable battery has been used as a power source for a remote control device (see, for example, Patent Document 1). As this battery, a primary battery or a secondary battery having a predetermined shape is used. When a primary battery is used, it is replaced with a new battery when the remaining battery level is low. In the case of using a secondary battery, when the remaining battery level is low, the battery is taken out and charged with a charging device.

JP 2008-288843 A

  By the way, in the remote control device disclosed in Patent Document 1, when the remaining amount of the primary battery in use decreases, there is a problem that it is necessary to replace the battery, which increases costs. In addition, when a secondary battery is used, a separate charging device for charging the secondary battery is required, and there is a problem that it is costly. Further, these points are not problems specific to the remote control device, but are widely applicable to portable devices using batteries.

  The present invention was created in view of the above points, and an object of the present invention is to provide a battery-type power supply device and a remote control device that do not require battery replacement and do not require charging using a special charging device. There is.

  In order to solve the above-described problems, a battery-type power supply device of the present invention includes a casing having a cylindrical shape, a permanent magnet capable of reciprocating in the longitudinal direction of the cylindrical shape within the casing, and movement of the permanent magnet within the casing. A coil that is arranged along the path and generates an electromotive force with the reciprocating movement of the permanent magnet; and a first charging circuit that rectifies the voltage that appears in the coil with the reciprocating movement of the permanent magnet and charges the storage element It has.

  Since the casing is equipped with a coil and a permanent magnet, the voltage that appears in the coil can be rectified by the movement of the permanent magnet and the storage element can be charged, so there is no need to replace the battery as in a conventional primary battery (dry battery), Moreover, it becomes possible to repeatedly charge without using a special charging device as in the case of a conventional secondary battery.

  Further, a second piezoelectric element is disposed at at least one end of the movement path of the permanent magnet, and generates a voltage when pressed by the permanent magnet, and a second storage element is charged using the voltage appearing in the piezoelectric element. It is desirable to further include a charging circuit. The combined use of power generation using a coil and a permanent magnet and power generation using a piezoelectric element can increase the amount of power generation.

  In addition, the power storage element described above is a capacitor, and it is desirable to further include a voltage stabilization circuit that generates a constant voltage based on the voltage across the capacitor. This facilitates obtaining a desired stable voltage.

  Moreover, it is desirable that the casing described above has the same shape as the cylindrical battery represented by R6 or R03 in the international standard or the Japanese Industrial Standard. As a result, it can be used in place of a conventionally used AA (R6) or AAA (R03) battery.

  In addition, the remote control device of the present invention uses the battery-type power supply device described above as a power source, charges the storage element by shaking the entire remote control device before the user uses it, and operates with the charged power. . As a result, it is possible to secure necessary operating power prior to use of the remote control device.

  Hereinafter, a remote control device according to an embodiment to which a battery-type power supply device of the present invention is applied will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating an overall configuration of a remote control device according to an embodiment. As shown in FIG. 1, the remote control device 1 of the present embodiment includes a control unit 10, an operation unit 12, an infrared signal transmission unit 14, and a battery type power supply device 20. The control unit 10 is for controlling the entire remote control device 1. The operation unit 12 has a plurality of push buttons and outputs a signal corresponding to the push button pressed by the user to the control unit 10. The infrared signal transmission unit 14 includes a light emitting diode and a driver circuit thereof, and the driver circuit turns on the light emitting diode at a timing corresponding to the drive signal output from the control unit 10. Specifically, the control unit 10 performs modulation processing corresponding to the pressed push button in accordance with the signal input from the operation unit 12, and directs the drive signal as the modulation signal to the infrared signal transmission unit 14. Output. As a result, modulated signals having different contents (for example, frequency, signal time length, number of repetitions, etc.) corresponding to the pressed push button are generated, and the infrared signal corresponding to the pressed push button is transmitted from the infrared signal transmitting unit 14. Is transmitted toward a light receiving unit (not shown) provided in a device (for example, a television broadcast receiver or an air conditioner) to be operated by the remote control device 1.

  The battery-type power supply device 20 is housed in a housing having a predetermined shape, and supplies a predetermined operating voltage to each part of the remote control device 1 described above. FIG. 2 is a perspective view showing the external shape of the battery-type power supply device 20. The casing of the battery-type power supply device 20 is, for example, a commercially available AA or AAA battery (such as a primary battery such as a manganese battery or an alkaline battery, a Ni-Cd battery, a nickel metal hydride battery, a lithium ion battery, or the like). Secondary battery) has the same shape, and the battery type power supply 20 supplies the same voltage as those of these commercially available AA or AAA batteries. The AA battery is a battery indicated by R6 in the international standard (IEC) or Japanese Industrial Standard (JIS), and the AA battery is indicated by R03 in the international standard or Japanese Industrial Standard. It is a battery.

  FIG. 3 is a diagram illustrating the structure of the battery-type power supply device 20. As shown in FIG. 3, the battery-type power supply device 20 includes a housing 200, a cylinder part 210, a coil 220, a permanent magnet 230, piezoelectric elements 240 and 242, buffer parts 250 and 252, and a circuit part 260.

  As described above, the casing 200 has, for example, the same cylindrical shape as that of an AA battery, and a plus terminal 202 and a minus terminal 204 are disposed at both ends thereof. The cylinder part 210 is for accommodating the permanent magnet 230 therein and for reciprocating the permanent magnet 230 in the longitudinal direction. In addition, the coil 220 is disposed in a predetermined range on the outer peripheral surface of the cylindrical portion 210 and including the center along the longitudinal direction. The permanent magnet 230 is magnetized in the longitudinal direction of the cylindrical portion 210. When the permanent magnet 230 is reciprocated in the longitudinal direction in the cylindrical portion 210, the magnetic flux intersecting with the coil 220 changes, so that an alternating voltage is generated at both ends of the coil 220.

  In addition, the piezoelectric element 240 and the buffering part 250 are arranged at one end along the longitudinal direction of the cylindrical part 210, and the piezoelectric element 242 and the buffering part 252 are arranged at the other end. Each of the piezoelectric elements 240 and 242 generates a voltage when the permanent magnet 230 collides with the buffering portion 250 (or 252) and a pressure is applied. Each of the piezoelectric elements 240 and 242 may be used by connecting a plurality of them in series so as to obtain a desired voltage (a voltage capable of charging a capacitor as a storage element described later). The buffer parts 250 and 252 absorb the impact when the permanent magnet 230 collides with the piezoelectric elements 240 and 242. For example, a coil spring or the like is used.

  The circuit unit 260 charges the capacitor using an AC voltage appearing at both ends of the coil 220 or a voltage appearing at both ends of the piezoelectric elements 240 and 242, and generates a constant voltage from the voltage across the capacitor.

  FIG. 4 is a circuit diagram of the battery-type power supply device 20 including the circuit unit 260. As shown in FIG. 4, the circuit unit 260 includes charging circuits 261, 262, 263, a capacitor 266, and a voltage stabilization circuit 268. Charging circuit 261 (first charging circuit) rectifies the AC voltage appearing at both ends of coil 220 and applies the DC voltage obtained by the rectification to both ends of capacitor 266 to charge capacitor 266. The charging circuit 262 (second charging circuit) charges the capacitor 266 by applying a voltage appearing at both ends of the piezoelectric element 240 (or a voltage obtained by stepping up or down the voltage) to both ends of the capacitor 266. Similarly, the charging circuit 263 (second charging circuit) charges the capacitor 266 by applying a voltage appearing at both ends of the piezoelectric element 242 (or a voltage obtained by stepping up or down the voltage) to both ends of the capacitor 266. The voltage stabilization circuit 268 generates a constant voltage (for example, a voltage of 1.5 V, which is the same as that of an AA or AAA type manganese battery) based on the voltage across the capacitor 266. This voltage is taken out through the plus terminal 202 and the minus terminal 204.

  The user of the remote control device 1 swings the entire remote control device 1 in the longitudinal direction of the cylindrical portion 210 of the battery-type power supply device 20 to reciprocate the permanent magnet 230 in the cylindrical portion 210. Since the permanent magnet 230 is moved relative to the coil 220 to generate a voltage at both ends of the coil 220, the capacitor 266 can be charged by the charging circuit 261. Further, when the permanent magnet 230 pressurizes the piezoelectric element 240 or 242, a voltage is generated across the piezoelectric elements 240 and 242, so that the capacitor 266 can be charged by the charging circuits 262 and 263.

  Generally, since the power consumed by operating the remote control device 1 is very small, the power required for this operation can be stored in the capacitor 266 by shaking the remote control device 1 before the operation.

  Moreover, since the battery-type power supply device 20 described above has the same shape and the same terminal voltage as an AA manganese dry battery or the like, the same components as those of a conventional remote control device are used for components other than the battery-type power supply device 20. Can do. In many cases, two AA manganese batteries are used in combination to turn on the light-emitting diodes included in the infrared signal transmitter 14, but in this case, the battery type having the external shape shown in FIG. Two power supply devices 20 may be combined and connected in series. Further, if necessary (according to a necessary voltage), three or more battery type power supply devices 20 may be used in combination.

  As described above, in the battery-type power supply device 20 of the present embodiment, the coil 220 and the permanent magnet 230 are provided in the housing 200, and the voltage appearing in the coil 220 is rectified by the movement of the permanent magnet 230 to charge the capacitor 266. Therefore, it is not necessary to replace the battery as in the case of a conventional primary battery (dry battery), and it is possible to repeatedly charge the battery without using a special charging device as in the case of a conventional secondary battery. In addition, the combined use of power generation using the coil 220 and the permanent magnet 230 and power generation using the piezoelectric elements 240 and 242 can increase the amount of power generation.

  In addition, by providing the voltage stabilization circuit 268 that generates a constant voltage based on the voltage across the capacitor 266, a desired stable voltage can be easily obtained. Further, by using the casing 200 having the same shape as the cylindrical battery represented by R6 (or R03) in the international standard or the Japanese Industrial Standard, the conventionally used AA type (R6) (or AAA) It can be used instead of the battery of the form (R03).

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, in the above-described embodiment, the battery type power supply device 20 used for the remote control device 1 has been described. However, the battery type power supply device 20 is a portable device other than the remote control device 1 (a device that can be shaken by a user). As a power source, the battery may be used instead of the battery.

  In the above-described embodiment, the power generation using the coil 220 and the permanent magnet 230 and the power generation using the piezoelectric elements 240 and 242 are used together. However, when the power generation amount is sufficient, the power generation using the coil 220 and the permanent magnet 230 is performed. And at least one of the piezoelectric elements 240 and 242 and its associated circuit may be omitted.

  In the above-described embodiment, the capacitor 266 is used as the power storage element. Instead, a power storage element other than the capacitor, for example, a secondary battery may be used. Further, when the terminal voltage of the capacitor 266 or the secondary battery used instead thereof is substantially the same as the terminal voltage of the AA or AAA battery, the voltage stabilization circuit 268 may be omitted. Good.

  According to the present invention, since the coil and the permanent magnet are provided in the housing, and the voltage appearing in the coil can be rectified by the movement of the permanent magnet to charge the storage element, the battery as in the conventional primary battery (dry battery) Replacement is not necessary, and charging can be performed repeatedly without using a special charging device like a conventional secondary battery.
