Description
The present invention relates generally to a method and apparatus for transferring electrical power in an electronic device and, more particularly, to the transferring of electrical power in a device that has two or more movably connected device parts, and possibly one or more detachable parts.
An electronic device, such as a mobile phone, may have two or more device parts movably connected to each other. If some or all movable parts of the device parts have one or more electronic components that need electrical power, but only one of the device parts has a battery or another type of power source, then electrical power must also be provided to the other device part.
It is desirable and advantageous to provide a method and apparatus for transferring electrical power from one device part to another.
The present invention is concerned with a short-range wireless power transmission between several moveable or detachable parts of an electronic device, which makes use of electromagnetic coupling, typically in the near field, at the microwave frequency. In an electronic device, such as a foldable or slidable mobile phone, both device parts have some electronic components that require electronic power but only one part has a power source. For example, a phone cover has a display but there is no power source in the phone cover. A receiver can be implemented in the cover to receive microwaves from a transmitter in the phone body. The receiver and the transmitter can be arranged such that, the antennas are placed as close to each other as possible in order to achieve best efficiency of energy and data transfer. If one pair of antenna is not enough, multiple antennas or antenna arrays can be used for this purpose. Different antenna pairs should be configurable for different purposes. According to one embodiment of the present invention, the phone cover has a separate antenna for receiving data from the transmitter in the phone body, for example.
Thus, the first aspect of the invention is a method for use in power transfer in an electronic device having a first device part mechanically coupled to a second device part. The method comprises:
providing a first electronic component in the first device; and
providing a second electronic component in a second device part, wherein the electronic device is operable in a first configuration and in a second configuration, such that
when the electronic device is operated in the first configuration, the second electronic component is configured for transmitting electromagnetic waves and the first electronic component is located adjacent to the second electronic component at a first distance for receiving the electromagnetic waves, and
when the electronic device is operated in the second configuration, the first electronic component is spaced from the second electronic component at a second distance greater than the first distance.
The first electronic component may comprise one or more antennas.
According to one embodiment of the present invention, when the electronic device is operated in the second configuration, the second electronic component is configured for transmitting data. The first device part further comprises an antenna for receiving the data. This antenna may be different and electrically separated from the first electronic component.
According to another embodiment of the present invention, the second device part has another antenna for transmitting data to the antenna in the first device part.
According to yet another embodiment, the second electronic component can also be configured for transmitting communication signals.
According to a different embodiment, communication signals are transmitted and received by a different antenna or pair of antennas.
According to a yet different embodiment, communication signals are transmitted and received by reusing the antenna pairs for electromagnetic wave transmission in the wireless power transfer scheme.
When the first electronic component is adjacent to the second electronic component, the power transferred from the second electronic component to the first electronic component can be carried out by microwave transmission, for example.
According to one embodiment of the present invention, the second electronic component comprises a multi-frequency antenna, wherein
when the electronic device is operated in the first configuration, the multi-frequency antenna is configured for transmitting electromagnetic waves in a first frequency range; and
when the electronic device is operated in the second configuration, the multi-frequency antenna is configured for transmitting and receiving communication signals in a second frequency range different from the first frequency range.
The first frequency range can be a millimeter-wave frequency range, and the second frequency range can be a microwave frequency range, for example.
The second aspect of the present invention is an apparatus, which comprises:
a second apparatus part mechanically coupled to the first apparatus part, the second apparatus comprising a second electronic component, wherein the apparatus is operable in a first configuration and in a second configuration, such that
when the apparatus is operated in the first configuration, the second electronic component is configured for transmitting electromagnetic waves and the first electronic component is located adjacent to the second electronic component at a first distance for receiving the electromagnetic waves, and
when the apparatus is operated in the second configuration, the second electronic component is spaced from the second electronic component at a second distance greater than the first distance.
According to one embodiment of the present invention, when the apparatus is operated in the second configuration, the second electronic component is configured for transmitting data. The data can be display data to be in a display panel in the first apparatus part, for example. The data can be received by a separate antenna in the first apparatus part in a wireless fashion or the same antenna in the first electronic component. Alternatively, the data is transmitted by a different transmitter in the second apparatus part.
In a different embodiment, data communications between the first apparatus part and the second apparatus part can also be carried when the apparatus is operated in the first configuration. Data communications can be carried out using the same antennas for wireless power transfer, or using different antennas.
The electronic device can be a foldable phone having a phone cover movably coupled to a phone body. The electronic device can also be a slidable phone or a phone having detachable parts. When the phone is operated in a closed position, a transmitter in the phone body can transfer electrical power to the phone cover via a receiver in the phone cover. When the phone is operated in an open position, the receiver may be located too far from the transmitter. In that case, the transmitter can be used to transfer data to the phone cover, for example.
The electronic device can be an MP3 player, a Communicator device, a personal digital assistance (PDA) or any electronic device that has two or more movably coupled device parts.

In an electronic device that has several device parts movably connected to each other and some or all of the device parts have one or more electronic components that need electrical power, the present invention uses a wireless means for transferring electrical power from one device part to another.
As shown in FIG. 1 a, an electronic device 1 has a first device part 10 and a second device part 50 movably connected to each other with a hinge 35. When the device 1 is in a closed position, the entire first device part is in close proximity to the second device part. As shown in FIG. 1 a, the first device part 10 has a display 12, a processor 14 connected to a charge storage device 20, such as a rechargeable battery. The first device part 10 also has a charging device 30 coupled to the charge storage device 20 so that it can charge the charge storage device 20. The charge storage device 20 is used to provide electrical power to the processor 14 and the display 12. The processor 14 can be a display driver or the like. In various embodiments of the present invention, the charging device 30 is an electromagnetic signal receiver. According to one embodiment of the present invention, the first device part 10 has another antenna 32 for receiving display data, for example.
The second device part 50 has a power source, such as a battery 60, and a processor 64 connected to an electromagnetic signal transmitter 70. The transmitter 70 can be an antenna and the processor 64 can be used to control the transmission of electromagnetic signals by the transmitter 70, for example. When the electronic device 1 is in a closed position, as shown in FIG. 1 a, the charging device 30 is located adjacent to the transmitter 70. As such, the charging device 30 can effectively receive the electromagnetic signals transmitted by the transmitter 70. The charging device 30 can also be an antenna. With the electrical energy received in a wireless fashion, the charging device 30 charges the charge storage device 20. The charging device 30 and the transmitter 70 can be two near-field communication (NFC) antennas, for example.
According to one embodiment of the present invention, when the device 1 is operated in an open position, the first device part 10 is turned away from the second device part 50 about the hinge 35. As shown in FIG. 1 b, the charging device 30 is no longer located adjacent to the transmitter 70. As such, the charging operation in the first device part 10 becomes less effective, and the transmitter 70 can be configured for data communication, for example. In one embodiment of the present invention, the transmitter 70 is used to transmit display data to the antenna 32 to be used in the display 12, for example.
It should be noted that the charging device 30 can be an antenna, for example, for receiving electromagnetic signals from the transmitter 70. The antenna 30 is under the control of the processor 14 such that, when the device 1 is operated in the closed position (FIG. 1 e), the antenna is configured for charging the charge storage device 20, and when the device 1 is operated in the open position (FIG. 1 f), the antenna 30 is configured for receiving data from the transmitter 70 and providing the data to the display 12. As such, the data receiving antenna 32 can be eliminated.
The electronic device 1 can be a foldable mobile phone, for example. In one embodiment of the present invention, when the mobile phone is operated in an open position, as shown in FIG. 1 b, the antenna 70 is used to send data to the display 12 via the antenna 32. In another embodiment, the device 1 has a different antenna 72 configured to transmit and receive data in communications signals under the control of the processor 64 when the mobile phone is operated in a closed position, as shown in FIG. 1 a, or in the open position, as shown in FIG. 1 b. Thus, the processor 64 can include a transceiver front-end having a duplexer, bandpass filters, amplifiers and other transceiver front-end components. The hinge 35 may comprise a switch which disables the charging function in the first device part when the mobile phone is operated in an open position.
In the embodiment as shown in FIGS. 1 a and 1 b, the antenna 30 and the antenna 70 are located near the hinge 35. In other embodiments, the antennas 30 and 70 can be located differently. For example, the antennas 30 and 70 can be located in a different end of the electronic device 1, as shown in FIGS. 1 c and 1 d. Moreover, the antennas 30 and 70 can be located in the front side, back side or the edge of both device parts, so long as they are located very close to each other in order to achieve a high efficiency in power transfer, when the device 1 is operated in the closed position.
When the device 1 is operated in the open position, the antenna 70 is configured to communicate with the antenna 32 in order to provide display data to the display 12, for example. In this embodiment, the antenna 70 can also be configured to communicate with an external device or network. In the external communication mode, the antenna 70 can be used to transmit and receive communication signals. The antenna 70 can be a multi-frequency antenna, configured to transmit microwave frequency signals for charging purposes, and to transmit and receive higher frequency signals for communication purposes, for example.
The electronic device can be arranged like a slidable mobile phone, for example. As shown in FIG. 2 a, when the slidable mobile phone 1 is operated in a closed position, it is similar to the foldable mobile phone as shown in FIG. 1 c, but the display 12 in the mobile phone 1 is located on a different side of the first device part 10. When the mobile phone is operated in an open position, the first device part 10 is slid against the second device part 50, as shown in FIG. 2 b. As such, the charging device 30 is no longer adjacent to the transmitter 70. In the embodiment as shown in FIGS. 2 a and 2 b, it is possible to implement another antenna 74 on the other end of the second device part 50 for communicating with the antenna 32 in order to provide display data to the display 12. When the mobile phone 1 is operated in the closed position, as shown in FIG. 2 a, the antenna 74 may be used for receiving communication signals, for example. When the device 1 is operated in the open position, as shown in FIG. 2 b, the antenna 70 may be used for transmitting and receiving communication signals, for example.
Alternatively, the device 1 can be slid open in a different direction as shown in FIGS. 2 e and 2 f. In this embodiment, it is possible to locate the antenna 32 to be adjacent to the transmitter 70 for effective data communication when the mobile phone 1 is operated in the open position. As such, the antenna 74 is not necessary. In this open position, antenna 32 and antenna 70 can also be used for efficient power transmission, because they are so close to each other.
According to another embodiment of the present invention, the device 1 may have one or more detachable parts. For example, the device part 10 can be separated from the device part 50, as shown in FIG. 2 d. As shown in FIGS. 2 c and 2 d, the device part 50 also has a display 42 so that the device part 50 can be used as a stand-alone communication device, for example. As in the embodiment as shown in FIG. 2 a, when the device 1 is operated in the closed position, the antenna 70 is used mainly to charge the charge storage device 20 by transmitting electromagnetic waves to the charging device 30, and the antenna 74 can be used to provide display data to the display 12 by communicating with the antenna 32. When the device 1 is operated in the open position, the antenna 32 may or may not receive display data from the antenna 74, depending on the separation distance. The antenna 70 may be used for transmitting and receiving communication signals.
The electronic device can also be arranged so that the first device part 10 can be rotated against the second device part 50 as shown in FIGS. 3 a and 3 b. As shown in FIG. 3 b, when the device 1 is operated in an open position, the charging device 30 is no longer adjacent to the transmitter 70.
It should be noted that, in one embodiment of the present invention, the electromagnetic signal receiver 30 is a passive device, such as a radio frequency identification (RFID) tag, for example.
The electromagnetic signal transmitter 70 and the electromagnetic signal receiver 30 can be of the same design or of different designs. For example, both the transmitter 70 and the receiver 30 can be a spiral antenna as shown in FIG. 4; a loop antenna as shown in FIG. 5; a dipole antenna as shown in FIG. 6, or a patch antenna as shown in FIG. 7. In some or all of these antennas, there may be a ground plane or a back plane located adjacent to the antenna. The antennas can be operated in the 60 GHz Ultra Wide Band (UWB) radio frequency range, for example. With the wavelength of the radio signals being in the millimeter range, the antennas can be sufficiently small to fit in a small electronic device. The antenna ground plane can be as small as 5 mm-by-5 mm, for example.
In an arrangement such as that shown in FIG. 6, the back plane can be a quarter of a wavelength apart from the dipole, for example. In an arrangement such as that shown in FIG. 7, the distance between the two patch antennas can be between 0.2 to 10 mm when the operating frequency is 65 GHz or 60 GHz, for example. The longer dimension of the patches can be 6 mm, for example, and the short dimension is about 2 mm, for example. It should be noted that distance between the transmitting antenna 70 and the receiving antenna 20 varies with the shape, the size of the antennas and the operating frequencies. Nevertheless, the principle of using two near-field communication antennas placed at close proximity for the transfer of electrical power is the same regardless of the choice and the design of the antennas. The choice and the design of the antennas may affect the power transfer efficiency.
In sum, the present invention provides a method for wireless power transfer between two or more movably or detachably connected device parts. The power transfer can be carried out by transmitting and receiving electromagnetic signals in the microwave frequency, for example. In an electronic device having a first part mechanically coupled to the second device part and the device operable in a first and a second configuration, the power and data transferring method comprises:
providing a first electronic component in the first device part, and
providing a second electronic component in the second device part of the electronic device, wherein the first device part is mechanically coupled to the second device part, such that
when the electronic device is operated in the second configuration, the first electronic component is spaced from the second electronic component at a second distance greater than the first distance, the electronic device is operated in the second configuration, the second electronic component is configured for transmitting data.
The data can be received by a separate antenna in the first apparatus part in a wireless fashion or the same antenna in the first electronic component. Alternatively, the data is transmitted by a different transmitter in the second apparatus part. In a different embodiment, data communications between the first apparatus part and the second apparatus part can also be carried when the apparatus is operated in the first configuration. Data communications can be carried out using the same antennas for wireless power transfer, or using different antennas.
providing a third electronic component in the first device part for receiving the data from the second electronic component, and a fourth electronic component in the second device part for transmitting data to the third electronic component.
providing a third electronic component in the first device part for receiving the data from the second electronic component, and reusing the second component in the second device part for transmitting data to the third electronic component.
In one embodiment of the present invention, when the electronic device is operated in the second configuration, the second electronic component is configured for transmitting communication signals. In one embodiment of the present invention, when the electronic device is operated in the second configuration, the second electronic component can still be configured for transmitting power only if the transmit and receive antennas are close enough, like in FIGS. 2 e and 2 f. In another embodiment of the present invention, communication signals are transmitted and received by a different antenna or electronic component.
According to one embodiment of the present invention, the second electronic component can be a multi-frequency antenna, such that
when the electronic device is operated in the first configuration, the multi-frequency antenna is configured for transmitting electromagnetic waves in a millimeter-wave frequency range, for example; and
when the electronic device is operated in the second configuration, the multi-frequency antenna is configured for transmitting and receiving communication signals in a microwave frequency range, for example.
In a different embodiment of the present invention, when the electronic device is operated in the first configuration, the multi-frequency antenna is configured for transmitting electromagnetic waves in a microwave frequency range, for example; and
when the electronic device is operated in the second configuration, the multi-frequency antenna is configured for transmitting and receiving communication signals in a radio frequency range, for example.
The present invention also provides an apparatus having a first apparatus part mechanically coupled to a second apparatus part, the apparatus operable in a first configuration and a second configuration. The apparatus comprises:

a second electronic component located in the second apparatus part, such that
when the apparatus is operated in the second configuration, the second electronic component is spaced from the second electronic component at a second distance greater than the first distance, and the second electronic component can be configured for transmitting data.

when the apparatus is operated in the first configuration, the multi-frequency antenna is configured for transmitting electromagnetic waves in a microwave range; and
