  The present invention relates to a non-contact charging device, a non-contact charging system and a non-contact charging method capable of charging various portable electronic devices in a non-contact manner, and in particular, a secondary battery built in a plurality of various portable electronic devices by electromagnetic induction. The present invention relates to a non-contact charging device, a non-contact charging system, and a non-contact charging method.

  In recent years, as portable electronic devices used around water such as an electric shaver and electric toothbrush, the main body and a dedicated holding body (cradle) for holding the main body and the portable electronic device from the holding body to the main body when in the holding state There has been proposed a non-contact charging apparatus configured to have a non-contact power transmission function for performing non-contact power transmission. Such a non-contact power feeding device realizes non-contact charging by including a non-contact power transmitting device on the holding body side and a non-contact power receiving device on the portable electronic device side of the main body.

  As a configuration of such a non-contact power transmission device and a non-contact power reception device, it is common to configure a primary coil on the non-contact power transmission device side and a secondary coil on the non-contact power reception device side. In the power transmission device, a voltage from a commercial power source is converted into a high-frequency AC voltage by a high-frequency inverter circuit and applied to the primary coil, thereby generating a high-frequency AC magnetic flux of 60 to 600 kHz in the primary coil. Patent Document 1 describes that an AC voltage induced by the AC magnetic flux in a secondary coil is converted into DC by a secondary rectifying and smoothing circuit and then fed to a secondary battery as a charging means. Yes.

  FIG. 8A and FIG. 8B show a circuit and a device configuration of the non-contact charging device disclosed in Patent Document 1. FIG. 8A is a perspective view showing the configuration of the non-contact charging device, and FIG. 8B is a circuit diagram showing a non-contact power transmission unit 40 for transmitting power and a power for receiving power. A non-contact power receiving unit 50 is provided to transmit power from the non-contact power transmitting unit 40 to the non-contact power receiving unit 50 in a non-contact manner using an electromagnetic induction action. Each of the non-contact power transmission unit 40 and the non-contact power reception unit 50 is accommodated in a resin case (not shown). Therefore, the electrical contact portion (plug) is not exposed to the outside.

  The non-contact power transmission unit 40 includes a primary side ferrite core 41 and a primary side FPC (Flexible Printed Circuit) substrate 42, and a soft magnetic primary side ferrite having a rectangular parallelepiped shape on the lower surface of the primary side FPC substrate 42. A core 41 is arranged. A pair of flat spiral coils 43 and 44 are disposed on the primary side FPC board 42, and the pair of flat spiral coils 43 and 44 are wound so that the directions of magnetic fluxes generated are opposite to each other. A resonance capacitor 45 is mounted in series. On the primary side FPC board 42, a pair of planar spiral coils (hereinafter referred to as spiral coils) 43 and 44 and a resonance capacitor 45 are constituted by a switching power source as shown in FIG. 8B. Wiring for connecting in parallel with the output of the conversion circuit 46 is formed. The resonance frequency defined by the inductance of the spiral coils 43 and 44 and the capacitance of the resonance capacitor 45 is set in the range of 100 Hz to 300 Hz.

  The non-contact power receiving unit 50 includes a secondary side ferrite core 51 and a secondary side FPC board 52, and the secondary side FPC board 52 is disposed on the lower surface of the soft magnetic secondary side ferrite core 51 having a rectangular parallelepiped shape. Yes. A pair of planar spiral coils 53, 54, a resonance capacitor 55, a rectifying diode 56, and a smoothing capacitor 57 are connected under the secondary side FPC board 52 as shown in FIG. Wiring for connecting the pair of spiral coils 53, 54, the resonance capacitor 45, the rectifying diode 56, and the smoothing capacitor 57 is formed on the secondary FPC board 52.

  The spiral coils 53 and 54 are arranged so as to face the spiral coils 43 and 44, respectively, and are wound so that the direction of the current generated by the change of magnetic flux generated in the spiral coils 43 and 44 is the same direction. Connected in series. The spiral coils 53 and 54 connected in series are connected in parallel with the resonance capacitor 55. The resonance frequency defined by the inductance of the spiral coils 53 and 54 and the capacitance of the resonance capacitor 55 is the same as the resonance frequency defined by the inductance of the spiral coils 43 and 44 and the capacitance of the resonance capacitor 45 in the power transmission unit 40. Set to

  The rectifying diode 56 and the smoothing capacitor 57 are connected in series, and the smoothing capacitor 57 is connected in parallel to the resonance capacitor 58. The output terminals T1 and T2 at both ends of the smoothing capacitor 57 are connected to the secondary battery 59 via the voltage regulator 58 to charge the secondary battery 59 in a non-contact manner.

  In the non-contact charging apparatus having such a configuration, the magnetic flux generated by the spiral coils 43 and 44 is, for example, at a certain moment, for example, the spiral coil 43 → the primary ferrite core 41 → the spiral coil 44 → the spiral coil 54 → secondary. The magnetic flux is prevented from leaking to the outside because it passes through a closed magnetic path consisting of a path in the order of the side ferrite core 51 → the spiral coil 53 → the spiral coil 43. Therefore, even if an electronic component such as the resonant capacitor 55 is arranged close to the secondary ferrite core 51, the electronic component is not affected by the leakage magnetic flux. For example, a foreign metal is arranged in a range of 0 to 5 mm. However, it is disclosed that induction heating is not performed.

  The non-contact charging device in the description of the disclosure in Patent Document 1 is an electronic device having a one-to-one non-contact power transmitting device and a non-contact power receiving device, and assumes that a plurality of electronic devices are charged. There wasn't.

  On the other hand, in Patent Document 2, as a method of charging a plurality of portable electronic devices, a plurality of portable telephones are mounted on a non-contact power transmission unit, and a plurality of portable phones are charged simultaneously. A contactless charging device is disclosed. As a result, conventionally, an AC adapter or cradle for power transmission is required for each mobile phone. However, according to Patent Document 2, only one AC adapter or cradle for power transmission is required. There is disclosure that it is no longer necessary to carry around.

  9A and 9B are a block diagram of a non-contact charging device disclosed in Patent Document 2 and a perspective view for explaining a charging method for a plurality of portable telephones placed on the non-contact power transmission device. is there.

  9 (A) and 9 (B) show the non-contact charging device disclosed in Patent Document 2, and in FIGS. 9 (A) and 9 (B), 60 is a non-contact power transmission unit, which is substantially rectangular. The case 61 has a flat spiral primary coil 62. Although not shown, it can be connected to a commercial power outlet or the like via a plug, and the magnetic flux generated based on the voltage supplied to the primary coil 62 constitutes a portable electronic device as shown by an arrow A in FIG. An electromotive force is induced in the secondary coil 71 in the mobile phone 70A by electromagnetic induction. The voltage induced by the secondary coil 71 of the non-contact power receiving unit 72 of the mobile phone 70A is rectified via the rectifier circuit 73, smoothed by the smoothing circuit 74, and passed through the regulator 75 and the charge control circuit 76. The secondary battery 33 in 70A is charged. Reference numeral 77 denotes a control means to which a secondary battery voltage and a regulator voltage are supplied from the secondary battery 33 and the regulator 75.

  FIG. 9B shows that a plurality of portable telephones 70A, 70B, and 70C are detachably mounted or held on the casing 61 of the non-contact power transmission unit 60, and the plurality of portable telephones 70A, 70B, and 70C can be charged simultaneously. It shows the state to make.

However, in the technique disclosed in Patent Document 2 described above, the non-connection power receiving unit 72 and the secondary coil 71 must be built in the portable telephone as an electronic device, and the portable telephones 70A and 70B which have been miniaturized. 70C, it is difficult to incorporate such a non-contact power receiving unit 72 and the secondary coil 71, and in a portable telephone having a contact charging terminal that has been widely used in the past, a non-contact charging device There is a problem that a plurality of portable telephones cannot be charged at the same time as in the case of a contactless charging system.

  Hereinafter, a non-contact charging apparatus, a non-contact charging system, and a non-contact charging method according to an embodiment of the present invention will be described in detail with reference to FIGS. The non-contact charging device 1 of the present invention includes a non-contact power transmission device 2 and a non-contact power receiving module 3 as shown in FIG. The non-contact power transmission device 2 includes an FPC wiring board on which a primary coil 4 wound in a plane spiral shape or a spiral shape and a switching regulator circuit 6 are mounted in a case 2A made of a substantially rectangular flat synthetic resin or the like. It is arranged. Reference numeral 7 denotes a power plug to be inserted into a commercial power outlet. The housing 3A on the non-contact power receiving module 2 side is made of a substantially flat, flat, small synthetic resin or the like, and the minimum configuration disposed in the housing 3A is also a flat spiral or spiral secondary coil 8. And an FPC wiring board on which the rectifier circuit 10 is mounted and a terminal 11 that can be connected to an electronic device such as a portable telephone.

  FIG. 3 is a block diagram for explaining the overall circuit configuration of the non-contact charging system and the non-contact charging method of the present invention described with reference to FIGS. 1 and 2, and the non-contact power transmission device 2 is attached to the synthetic resin casing 2A. By inserting the attached power plug 7 into a commercial power outlet, the commercial AC voltage drives the primary coil 4 at a high frequency via a rectifying and smoothing circuit and a switching regulator circuit 6. The voltage induced in the primary coil 4 induces a predetermined voltage in the secondary coil 8 in the housing 3A of the non-contact power receiving module 3 that is spaced apart by electromagnetic induction. A high-frequency current due to a voltage induced in the secondary coil 8 is rectified by a rectifier circuit 10 or a charging circuit (not shown), and the charging current constitutes a portable electronic device such as a digital camera or a PDA (Personal Digital Assistants). ) The secondary battery 33 in the digital camera 18 is charged through the terminal (plug) 11 fitted to the contact charging terminal (plug seat) 19 provided in the 18 camera casing 18A.

  As a structure of the secondary coil 8 for power reception on the non-contact power reception module 3 side, a cored coil having an iron core or ferrite or an air core coil may be used as in the conventional product. At that time, in order to make it easier to collect the magnetic field in the primary coil 4 and the secondary coil 8 so as not to reduce the power transmission efficiency, the ferrite plate 5 is provided on the back side of the primary coil 4 and the secondary coil 8 as disclosed in Patent Document 1. A magnetic sheet such as 9 or 9 is preferably pasted.

FIG. 4 shows another configuration of the non-contact power receiving module 3 used in the non-contact charging device 1 of the present invention, and the same reference numerals are given to corresponding parts with the non-contact power receiving module 3 shown in FIGS. However, although redundant explanation is omitted, depending on the design of the primary coil 4 and the secondary coil 8 for power transmission / reception induction and the number of the plurality of portable electronic devices 18 to be charged, the efficiency of power transmission is reduced and it is changed to heat. However, in order to prevent such a problem of heat generation, in the case of FIG. 4, for example, a ceramic plate 12 is attached to the back of the FPC wiring board constituting the charging circuit 13 to form a heat spreader. On the lower side of the ceramic plate 12, a secondary coil 8 is laminated in the housing 3A via a ferrite plate 9. As such a heat spreader, the material itself of one or both printed wiring boards of the non-contact power transmission device 2 or the non-contact power receiving module 3 is made of ceramic, or a ceramic plate 12 is disposed on the FPC wiring board as shown in FIG. You can also As such a heat spreader, ceramics having high thermal conductivity such as alumina (Al ₂ O ₃ ), silicon nitride (Si ₃ N ₄ ), or aluminum nitride (AlN) can be used.

  Furthermore, a certain communication circuit for performing device authentication and information transmission can be provided on the contactless power transmission device 2 and the contactless power receiving module 3 side. That is, the non-contact power receiving module 3 is dedicated to a certain portable electronic device 18, incorporates various information data for device authentication, and is provided with an information data transmission circuit, so that the portable device connected to the non-contact power receiving module 3 side. The information data of the electronic device 18 for information, for example, the information data such as the capacity of the secondary battery 33 for charging and the remaining charge time is reflected in the circuit of the non-contact power transmission device 2 through the information data transmission circuit, thereby transmitting efficiency. Can be optimized. As an information transmission means in the non-contact charging module 3, infrared or visible LED communication, a communication method provided with another coil, a Bluetooth wireless system, a wireless LAN, or the like (see Patent Document 3 and Patent Document 4) The described method is conceivable, but not limited thereto.

  Further, for example, a terminal for transmitting information data is also incorporated in the contact charging terminal 19 of the portable telephone 18 constituting the portable electronic device 18, and the contactless power transmission device 2 side will be described later, such as USB (Universal serial bass), IEEE 1394, etc. It is also possible to transfer various data such as images, texts, music and the like between the portable electronic device and the computer by connecting to the computer via the interface bus.

  The terminals 11 of the non-contact power receiving module 3 as described with reference to FIGS. 1 to 4 are fitted to the charging terminals 19 built in the camera housing 18A of the digital camera 18 as shown in FIG. Is done. By placing these on the non-contact charging device 2, various information data of the digital camera 18 as a portable electronic device is sent to the non-contact charging module 3 and fed back to the non-contact power transmitting device 2 side to be inside the digital camera 18. The charging of the secondary battery 33 is started.

  By providing an information data transmission circuit in the non-contact power receiving module 3 as described above, the non-contact power transmitting device 2 recognizes the presence of the power receiving module 3 and information such as a coupling coefficient between the primary coil 4 and the secondary coil 8. Therefore, safe and reliable charging is possible. When a non-contact power receiving module 3 and a metal foreign object such as a coin or a clip are placed on the non-contact power transmitting apparatus 2 at the same time, the induced magnetic field concentrates on the metal and the non-contact power receiving module 3 and the non-contact power transmitting apparatus 2 and the foreign object. Since the coupling coefficient between the metal and the like greatly changes, the non-contact power transmission device 2 recognizes the presence of foreign metal, detects the metal as a foreign material, and activates the alarm means, or from the non-contact power transmission device 2 The power transmission should be cut off. Of course, when only the foreign metal is placed on the non-contact power transmission device 2, information data transmission between the non-contact power transmission device 2 and the portable electronic device 18 is not performed. You may make it interrupt.

  As described above, when the contactless power receiving module 3 is attached to the portable electronic device 18, electromagnetic waves from the contactless power transmission device 2 side are different from the portable electronic device 18 in which the secondary coil 8 is built. There is almost no entry into the portable electronic device 18, and the portable electronic device 18 may not be provided with a shielding structure for countermeasures against electromagnetic waves, and the portable electronic device 18 may not be adversely affected by electromagnetic waves. It is done.

  Further, by providing two or more primary coils 4 on the non-contact power transmission device 2 side, even if there are a plurality of non-contact power receiving modules 3 and portable electronic equipment 18 side, the place to be placed on the non-contact power transmission device 2 Thus, it is possible to charge a plurality of portable electronic devices 18 without reducing power transmission efficiency. For example, by providing a reactance detection circuit that detects the reactance of each of the plurality of primary coils 4 on the non-contact power transmission apparatus 2 side, it is detected where the portable electronic device 18 is placed on the non-contact power transmission apparatus 2. Thus, it is possible to stop power transmission to the secondary coil 8 in a portion where the secondary coil 8 is not placed. On the other hand, although the efficiency is reduced, the primary coil 4 of the contactless power transmission device 2 is made smaller than the secondary coil 8 in the contactless power receiving module 3, so that the user mounts the portable electronic device 18 on the contactless power transmission device 2. You can place it without worrying about the position.

  FIG. 6 illustrates a state in which the digital camera 18B and the portable telephone 18C as a plurality of portable electronic devices in which the terminal 11 of the contactless power receiving module 3 is inserted into the contact charging terminal 19 are charged in a contactless manner. As an example, four primary coils 4A to 4D for power transmission are used. With this structure, the two portable electronic devices 18 (18B, 18C) can be charged simultaneously. A Bluetooth wireless system is attached to each of the non-contact power transmission device 2 and the non-contact power reception module 3, and the charging status of the secondary battery 33 on the portable electronic device 18 side and the approximate position where the non-contact power reception module 3 is placed are determined. If feedback is made to the non-contact power transmission device 2 side, power can be efficiently transmitted to the portable electronic device 18. In the configuration of FIG. 6, the power loss at the time of power transmission can be reduced by stopping power transmission at the two locations of the primary coils 4 </ b> A and 4 </ b> B on which the non-contact power receiving module 3 is not mounted.

  FIG. 7 shows a configuration in which a non-contact power receiving module 3 </ b> C is attached to a PDA 18 </ b> D as a portable electronic device 18 and the non-contact power transmission device 2 is connected to a notebook computer 20 with a USB cable 21. For the information transmission of the non-contact power transmission device 2 and the non-contact power reception module 3D, the primary coil 4 and the secondary coil 8 built in the housings 2A and 3A of the non-contact power transmission device 2 and the non-contact power reception module 3D are different. The information data detection primary coil 4E and the information data detection secondary coil 8A are used. With this configuration, it is possible to transfer information such as images, schedules, and sentences between the notebook computer 20 and the PDA 18D in a non-contact manner, and simultaneously charge the PDA 18D.

  6 and 7, the digital camera 18B, the mobile phone 18C, and the PDA 18D are used as the target portable electronic devices 18, respectively, and Bluetooth wireless is used for information transmission between the contactless power transmission device 2 and the contactless power receiving module 3. Although the information data detection primary coil 4E and the information data secondary coil 8A for guidance and guidance are used, the present invention is not limited to this. Further, the primary coils 4A to 4D on the non-contact power transmission device 2 side may use only one primary coil 4A, for example, depending on whether or not the plurality of portable electronic devices 18 are charged, or the plurality of primary coils 4A to 4A. 4D may be used.

  According to the present invention, a non-contact power supply module is attached to a portable electronic device that is charged from a conventional contact-type AC adapter, so that a plurality of portable electronic devices to which the non-contact power supply module is attached can be converted into a single non-contact power transmission. It is possible to charge at the same time using the device. Furthermore, by incorporating an information data transmission circuit in this, information transmission, foreign matter detection on the power transmission side, and optimization of charging are facilitated. Examples of portable electronic devices that can be used include, but are not limited to, mobile phones, PDAs, digital cameras, digital video cameras, portable recording / playback devices, portable televisions, and notebook computers. . In the above description, the case where a plurality of non-contact power receiving modules and a plurality of portable electronic devices are mounted on a non-contact power transmission device has been described. However, a plurality of primary coils and secondary coils are comb-shaped so that they are magnetically induced.
