[0043] The panel device according to the present disclosure will be described in detail below with reference to the accompanying drawings. Figure 1 and 2 As shown, the panel device according to the present disclosure includes a panel body 1 and a base 2. The panel body 1 and the base 2 are separate components, and the panel body 1 can be removably coupled to the base 2. Figure 1 The panel body 1 and the base 2 are connected in a connected state. Figure 2 The panel body 1 is shown in a separated state from the base 2 .

[0044] In one embodiment, Figure 1 As shown, the panel body 1 has a generally cylindrical structure. However, those skilled in the art will appreciate that the panel body 1 is not limited to the shape shown in the figure, and can have any suitable shape according to practical applications. For the sake of clarity, the panel device of the present disclosure is described below in the shape shown in the figure.

[0045] Figure 3 1 is an exploded perspective view of a panel device according to an embodiment of the present disclosure, showing various components of a panel body 1 and a base 2 . Figure 3 yes Figure 1 A detailed structural diagram of the present invention is provided, wherein for the purpose of simplifying the depiction, certain connection structures are omitted or simplified to highlight the improved structure of the panel device.

[0046] The panel body 1 and the base 2 are separate components. The charging and communication circuits respectively arranged in the panel body 1 and the base 2 can be configured to transmit power and signals wirelessly, so that the electrical requirements involved in the electrical accessories can be met and can be more conveniently removed and used portable.

[0047] The base 2 is usually used for installation on a wall, for example, in a concealed wall box. Figure 3 As shown, the base 2 includes a cover plate 201, a base power module 202, a lining plate 203, a frame 204, an outer frame 205 and a bottom box. The bottom box is composed of two shells 206 and 301, and the lining plate 203, the outer frame 205 and the bottom box are all fixed or supported by the frame 204. The frame 204 is used to be installed in a wall concealed box, thereby installing the base 2 in the wall concealed box.

[0048] The base power module 202 includes an AC power source and a DC power source for wireless charging, which are respectively arranged in the bottom box (having shells 206 and 301) and the lining plate 203, and the power source also includes surrounding components arranged in the lining plate 203. Figure 3 In the figure, for the sake of simplicity and clarity, only the surrounding components of the base power module 202 are shown. After the base power module 202 is installed, the outer frame 205 and the cover plate 201 can be installed, wherein the cover plate 201 covers the liner plate 203.

[0049] The base 2 may also be provided with a mounting recess 20 for receiving the panel body 1. In the illustrated embodiment, the mounting recess 20 is provided on the cover plate 201, and the shape of the mounting recess 20 is formed to be suitable for receiving the panel body 1. The base power module 202 may be designed to be arranged near the mounting recess 20 so as to interact with relevant components in the panel body 1.

[0050] like Figure 1-3 As shown, the panel body 1 includes a shell 10 and a bottom portion 105. In the illustrated embodiment, the shell 10 can be roughly cylindrical in shape, and the shell 10 and the bottom portion 105 together form an internal space. The shell 10 includes a top 11 facing the user and a columnar side extending from the top 11. In one embodiment, the top 11 is preferably provided with a display 12 for operation. In a further embodiment, the display 12 can extend along the top 11 to the area of ​​the side and, for example, a liquid crystal display panel 121 inserted into the area, or the displayed areas can also be spliced ​​with each other to display different contents. For example, the encapsulation structure as the display area can be coated with glass or a transparent, translucent polycarbonate (PC) material, so that different types of colors can be displayed in different positions, such as emitting light and displaying images while performing actions.

[0051] A sleeve 101 can be arranged in the internal space of the panel body 1. The shape of the sleeve 101 can be designed to be roughly similar to the shape of the shell 10, for example, it is also cylindrical. The size of the sleeve 101 can be designed to be slightly smaller than the size of the shell 10 so that it can be arranged inside the shell 10 in a nested manner.

[0052] The housing 101 is configured to accommodate and hold various functional modules. In the illustrated embodiment, the housing 101 has a plurality of through holes, which facilitate the interaction between the user and the functional modules. In one embodiment, when it is desired that the panel device according to the present disclosure has a voice recognition function, a voice recognition module, such as a microphone / speaker 131, can be placed in the panel body 1. In this case, the microphone / speaker 131 can pass through the through hole on the housing 101. Correspondingly, a channel 13 is provided on the side of the housing 10, and these channels 13 correspond to the through holes on the housing 101, so that the user can perform voice input through the voice recognition module when in use. The channels on the side of the housing 10 and the through holes on the housing 101 can be symmetrically arranged so as to arrange these functional modules more evenly. It will be appreciated by those skilled in the art that the above-mentioned functional modules may include any other suitable functional modules known in the art, such as a playback device, etc.

[0053] The bottom portion 105 of the panel body 1 is used to contact the base 2, specifically, the bottom portion 105 contacts the mounting recess 20 of the base 2. The bottom portion 105 has a surface for charging contact and an outer edge that is smoothly matched with the surface, and the outer edge extends from the surface to the side wall to form an arc or slope area. This area is used to allow the panel body 1 to sink into the mounting recess 20 in the center of the base 2 to align the respective related sensing components in the panel body 1 and the base 2. Preferably, each component can be designed to be arranged as closely as possible. For example, the base power module in the base 2 can be arranged around the mounting recess 20 so as to be arranged coplanar with the sensing components of the sensing module in the panel body 1.

[0054] An induction module may also be provided in the internal space of the panel body 1. In the illustrated embodiment, the induction module may include an induction component 104 and an associated circuit board 102, wherein the induction component 104 may be in the form of a magnetic induction coil. The circuit board 102 is electrically connected to the induction component 104 and to the above-mentioned functional modules accommodated in the internal space of the panel body 1, so as to transfer the power obtained by the induction component 104 from the base power module 202 to each functional module.

[0055] In one embodiment, a baffle 103 may be further provided in the panel body 1, and the induction component 104 may be placed in the baffle 103 and in the space enclosed by the baffle 103 and the bottom portion 105. As described above, the base power module 202 may be arranged around the mounting recess 20 of the base 2, and when the panel body 1 is mounted on the base 2, the bottom portion 105 of the panel body 1 engages with the mounting recess 20 of the base 2, so that the induction module (specifically, the induction component 104) in the panel body 1 is coupled with the base power module 202 of the base 2, so that the induction component 104 can obtain power from the base power module 202 in the base 2 in a wireless manner across the bottom portion 105. Among them, the baffle 103 has electric contacts arranged on the front and back. In one embodiment, the electric contacts may be designed as a bent structure to connect the circuit board through the through hole on the sleeve 101.

[0056] In one embodiment, the panel body 1 can be fixed in the base 2 by magnetic means. The magnet used for this magnetic method can be placed in the center of the sleeve 101 and preferably separated from the above functional modules, so that the circuit board 102 for providing signal processing can also have a hollow structure.

[0057] In some embodiments, the base 2 may be provided with a coupling charging area at the back of the mounting recess 20 or in the surrounding area of ​​the mounting recess 20 for wirelessly charging the adapted panel body 1 placed in these areas. For example, when the bottom portion 105 is spherical, the panel body 1 is allowed to rotate appropriately within the space defined by the mounting recess which is also spherical. Here, the base power module 202 may be placed in a central position such as the base 2. In this way, a processing circuit may be provided at the bottom of the base power module 202 in the base 2 to couple the base power module 202 and control the way in which the base power module 202 transmits electrical energy to the external space, such as frequency, power or similar elements.

[0058] In one embodiment, the wireless charging method between the panel body 1 and the base 2 can be a near-field resonance type, a coupling type or an electromagnetic mutual induction type or a combination thereof. For example, in the near-field resonance charging method, the near-field resonance power supply may include a high-frequency RC resonance circuit, which transmits electrical energy through a near-field magnetic coupling method that forms a resonance channel between the base power module 202 and the induction component 104 serving as a resonance circuit.

[0059] In some embodiments, the base power module can be an independent power supply unit, such as an isolated power module provided in an electrical accessory, or it can also be in a user device such as a desktop or laptop computer. In other embodiments, the base power module can be in the form of a portable unit, such as a device 4 that can be connected to a desktop computer and used as a power module, thereby providing a modification or enhancement of the electrical functions of the panel body 1, for example, Figure 4 As shown, in another embodiment according to the present disclosure, the panel body 1 can be coupled with a device 4, which can be a playback device and can also be used as a power module. Specifically, the panel body 1 can be engaged with the mounting recess 40 of the device 4, so that the device 4 is used to, for example, supply power to the panel body 1 or provide other electrical functions. In some other embodiments, the housing used to enclose the base power module or at least a portion of the housing can be used to extend the effective transmission range of the base power module.

[0060] In this way, the adapted panel body 1 can be powered directly from the base power module 202. In this way, when tuned to the appropriate frequency, the panel body 1 can wirelessly receive power from the base power module 202, and the tuned panel body 1 can be regarded as part of such a resonant circuit, which can include the base power module 202, the inductive component 104 and any other such tuned accessory devices.

[0061] As part of such a resonant circuit, each functional module has a corresponding load associated therewith that can be effectively sensed by the base power module 202. In this way, the resonant circuit can have a specific load that is changed by adding functional modules to or removing functional modules from the resonant circuit.

[0062] For example, if the user's resonant adapter device is placed within the sensing area of ​​the base power module, the load associated with the user device can be sensed by the base power module if and only if the user device is tuned to a predetermined value. In some cases, the user device placed within the sensing area of ​​the base power module 202 can use a standard communication protocol such as Wi-Fi or Bluetooth to transmit its initialization request for charging coupling. However, once incorporated into such a resonant circuit, the user device can use a reverse channel to establish resonance. Therefore, any changes in the characteristic load of such a resonant circuit can be transmitted to the base power module and used as control information for controlling various devices in the resonant circuit by allocating power.

[0063] In some embodiments, the panel body 1 may be configured to include a secondary resonant circuit (not shown in detail in the figure), which directly receives power from the base power module 202 and transmits at least a portion of the received power to other devices that need to be charged by other users. In this case, the inductive component 104 of the inductive module can be reused. For example, the coupling charging area includes the panel body 1 and one or more other user devices within the inductive area of ​​the base power module. In one embodiment, the functional module in the panel body 1 can be configured to synchronously receive wireless power directly from the base power module 202.

[0064] Figure 5Another embodiment according to the present disclosure is shown, in which the panel device includes a plurality of panel bodies 1 or other devices 4, which are respectively coupled to the base 2, so that the induction module in the panel body 1 or the device 4 is coupled with the base power module in the base 2. For example, these panel bodies 1 or the devices 4 are all coupled to the mounting recess 20 of the base 2 and arranged adjacent to each other.

[0065] For another example, in some applications, it is necessary to add a gain or identification circuit to the sensing area to control the base power module 202 to reduce power transmission and start other charging devices. This may be because the obstacles between the base power module 202 and the panel body 1 interfere with the direct power transmission. In this case, the device 4 can act as a secondary resonance source, so that at least a portion of the power transferred from the base power module 202 to the device 4 can continue to be transmitted to the adjacent panel body 1 through the secondary resonance circuit in the device 4. In this way, the power loss caused by any obstacle to the panel body 1 can be compensated by receiving power from the device 4. This compensation system can be transient or can be continuously executed as long as the control circuit located in the circuit board 102 determines that the required constant power cannot be received directly from the base power module 202. In other cases, re-placing the user device in the sensing area will reduce the transmission power available for the device 4. In this case, if the battery in the panel body 1 is fully charged or does not need to be recharged, the device 4 can be decoupled or decoupled from the charging circuit while still maintaining the secondary resonance that provides power to another device 4.

[0066] In some embodiments, a verification circuit is also provided in the base 2, which is electrically connected to the processing circuit to serve as the base power module for identifying and verifying the external device to be charged. In addition, the verification circuit can extend the extended transmission range of power that can be provided by the base power module 202 included in the base 2. In some cases, the verification circuit can trigger a secondary resonance to transmit electromagnetic waves from the base power module 202 to other devices, while in other cases, the verification circuit may also include its own built-in base power module. Through its own built-in base power module, the verification circuit can provide additional power to other devices in the coupling charging area (or bypass obstructions) that is separate from the power provided by the base power module included in the base 2. In some cases, the shell of the panel body 1 or at least a portion of its structure can be used as a resonant coupling circuit as an extension of the base power module.

[0067] In other embodiments, this hybrid resonant power supply can improve the lower wireless power transmission capability of the base power module to match the large power charging requirements such as those required by lithium-ion polymer batteries. For example, when the panel body 1 is coupled to a mobile phone, a user's personal digital device, etc., the power consumption is relatively large, so a larger amount of power transmission may be required to charge or at least maintain the normal operation of the circuit board 102, so in the above-mentioned cases, it may be greater than the basic wireless power that the base power module 202 can originally provide. Therefore, it will be difficult for us to use the base power module 202 to fully charge these batteries.

[0068] However, in order to meet this need, a transient charge storage device (such as a capacitor, a super capacitor, etc.) charged by the wireless power transmitted by the receiving base power module 202 can be used to temporarily store part of the basic charge before the charge is transferred to the battery. In this way, once enough basic charge is stored in the transient charge storage device, it can be used to charge the battery. For example, a capacitor, a capacitor charging circuit (which can receive wireless power from the base power module 202), a battery, and a battery charging circuit are also provided in the panel body 1 (such as the circuit board 102). In such an embodiment, the wireless power provided by the base power module 202 can charge the above capacitor slowly or intermittently. Once enough charge is stored in the capacitor, the capacitor charging circuit senses the capacitor voltage and switches the fully charged capacitor to the battery via the battery charging circuit. In this way, the charge stored in the capacitor can be used to increase the charge of the battery. Once the capacitor is discharged, for example, when it is determined by the capacitor charging circuit, the capacitor can receive wireless power from the base power module 202 again.

[0069] In addition, under such a wireless power supply environment, the base 2 can also wirelessly transmit data to the panel body 1 (for example, using NFC) to enhance the user experience, which can eliminate the inconvenience caused by plugging and unplugging data cables and provide users with an effective data transmission environment that is easy to use and mobile. In this way, data transmission interaction may include, for example, the base power module 202 provides wireless power to any device within the sensing range with a predetermined amount of power and wirelessly sends data to another device. For example, the amount of power transmitted between the base power module 202 (having a resonant source circuit) and the panel body 1 (having a resonant receiving circuit) receiving wireless power can be tuned by the above transmission method to reasonably control the resonant receiving circuit. When tuning the panel body 1, the tuned panel body 1 can become part of this resonant circuit. The coupling matching load associated with the panel body 1 can be sensed by the base power module 202. This coupling matching load can be used by the base power module 202 to determine the predetermined power transmission load of the resonant circuit and how to distribute the power required by each of the various powered devices in the transmission path of the resonant circuit. On the other hand, when a device is decoupled, the device no longer resonates with the base power module 202 and is effectively removed from the resonant circuit, thereby receiving substantially no additional power or being sensed.

[0070] As described above, various external environmental factors may have a significant impact on the transmission efficiency from the base power module 202 to the powered device in the resonant circuit transmission path. For example, certain metal or plastic housings may interfere with the power transmitted by the electromagnetic coupling between the base power module 202 and the powered device and the transmission efficiency, which may affect the panel body 1 or the device 4 to perform necessary electrical functions and increase the possibility that a specific device may not have enough power to operate at peak efficiency to perform certain functions. For example, if the panel body 1 moves within an obstacle interference area, the base power module 202 may attempt to modify the selected resonant frequency or matching impedance to determine that the panel body 1 is wirelessly coupled to the sensing range of the base power module 202 again.

[0071] In one embodiment, the base power module 202 may determine that the power transmission efficiency has been reduced to below the minimum effective threshold of the device based on the signal feedback from the powered device affected by the obstacle interference. In response, the base power module 202 may perform wireless power transmission again by modifying, for example, the resonant frequency (such as a higher frequency) until the transmission efficiency is restored to above the threshold set by the processor. Or in some cases, by decoupling secondary or less used devices to remove them from this resonant circuit transmission path, so as to release power and provide it to those devices that need more power (or that the user is currently using). Sometimes, these operations of the processor can be performed in the background in a way that the user does not notice. In another embodiment, the base power module 202 is configured to change the phase, frequency and / or signal amplitude relative to the electromagnetic resonant coupling of other devices to optimize wireless power transmission.

[0072] Thus, in order to provide data communication between various devices coupled to the base power module 202, each device may also use a direct connection channel such as Bluetooth or Wi-Fi to provide coupling feedback to the base power module 202 or its attached processor. In this case, the Bluetooth or Wi-Fi module may be arranged in the base 2 and directly powered by the base power module 202 to avoid power outages. However, an indirect communication channel may also be used, for example, a coupled matching load of a resonant circuit transmitted by the number or type of devices wirelessly coupled to the base power module 202 may be used to form. Since each device has its own corresponding resonant matching load, that is, a matching impedance sensed by the base power module 202 when the panel body 1 is tuned to a predetermined resonant frequency, an indirect communication channel transmitted by the load state of one or more devices in the resonant circuit transmission path can be established with the base power module 202. For example, the base power module 202 may determine a specific load under the resonant circuit transmission path by calculating the total resonant load under the transmission path (i.e., sensing the load on the resonant circuit). Any change in the load may indicate a change in the state of the resonant circuit, which in turn may infer that one or more of the devices previously in the transmission path of the resonant circuit have been decoupled. In some cases, a specific communication protocol may be established between the base power module 202 and each device to tune the feedback of the device based on, for example, a tuning mode. In this way, a simple device identifier, for example, may be transmitted to the base power module 202. In this way, the base power module 202 is configured to identify and store device information of the device in the transmission path of the resonant circuit. This device-to-device communication channel is capable of transmitting simple interactive information. Such information may include, for example, a device identifier, a synchronization identifier, etc. It should be noted that this communication channel is independent of each other and is separate from other communication channels provided by, for example, Wi-Fi or Bluetooth.

[0073] To this end, the housing of the panel body 1 also includes a resonant antenna in a near field communication area located in the mounting recess 20 with the base 2, which is used to couple power. As mentioned above, the near field is an electromagnetic field generated around the resonant antenna, but the electromagnetic field may not be propagated or radiated from the resonant antenna sometimes. In one embodiment, the near field area generated by the resonant antenna is limited by the volume or shape of the antenna, and a magnetic type antenna of a single-turn / multi-turn loop antenna is used as a transmitting and receiving antenna system, and the magnetic near field amplitude is higher than the near field generated by certain types of antennas.

[0074] As shown in the figure, the resonant antenna can be controlled at a sufficiently low frequency and with a sufficiently large antenna size to achieve effective coupling to the smaller size antenna of the panel body 1 at an effective transmission distance greater than that of long-distance transmission and / or the electromagnetic field induction method mentioned above.
