[0035] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

[0036] In the description of the present application, "processor" may include hardware, software or a combination of the two. The processor may be a central processing unit, a microprocessor, an image processor, a digital signal processor or any other suitable processor. The processor has data and / or signal processing functions. The processor may be implemented in software, hardware or a combination of the two.

The term "at least one A or B" or "at least one of A and B" has a similar meaning to "A and / or B" and may include just A, just B or A and B. The singular terms "one" and "the" may also include plural forms.

[0037] Here we first explain some terms involved in this application.

[0038] Thermo Electric Cooler (TEC) is a refrigerator made using the Peltier effect of semiconductor materials. The Peltier effect refers to the phenomenon that when a direct current passes through a galvanic couple composed of two semiconductor materials, one end absorbs heat and the other end releases heat.

[0039] Qi2 magnetic technology: It is a wireless charging technology that uses the principle of magnetic resonance to achieve wireless charging through magnetic attraction. Compared with traditional electromagnetic induction charging technology, Qi2 magnetic attraction has higher charging efficiency and smaller size, which can achieve more portable and reliable wireless charging. It has a wide range of applications in mobile devices, smart watches and other fields.

[0040] PCBA: Printed Circuit Board Assembly, that is, printed circuit board assembly, refers to the entire process of a blank PCB board going through SMT mounting or DIP plug-in.

[0041] As described in the background technology, there are usually the following problems when mobile devices interact with driving devices: when transmitting data via WiFi and Bluetooth, the bandwidth is low, the latency is high, and there is often interference, making it impossible to share high-bandwidth content in real time, and it is even more impossible to share the computing power of mobile devices with driving devices; mobile devices have a short life cycle and a fast update speed, while driving devices have a long life cycle and a slow update speed. Smart cockpit processing chips can easily lag behind mobile devices and cannot meet the computing power growth needs of user scenarios; mobile devices often heat up when charging, resulting in an inability to continue charging and data transmission.

[0042] In order to solve the above problems, the present application provides a wireless charging device, a communication method, a communication system and a storage medium.

[0043] In some embodiments, the wireless charging device provided in the present application includes at least one communication chip, a communication interface, a transmitting coil, a magnetic attraction device, a semiconductor refrigerator, a heat dissipation structure, and an air duct structure.

[0044] Among them, the communication chip is arranged at the center position of the transmitting coil for connecting to the mobile device, and the communication chip includes at least one millimeter wave communication chip; the communication interface is used for connecting to the driving device.

[0045] In other embodiments, the wireless charging device provided in the present application may further include a housing, a fixing module, an electromagnetic shielding module, a PCBA circuit board, and a connector.

[0046] See attached Figure 1 , Figure 1 FIG. 1 is an exploded view of a wireless charging device according to an embodiment of the present application. Figure 1 As shown, the wireless charging device in the embodiment of the present application mainly includes a magnetic attraction device 1, a transmitting coil 2, a communication chip 3, a heat dissipation structure 4, a TEC 5, a duct structure 6, a housing 7, a fixing module 8, an electromagnetic shielding module 9, a PCBA circuit board 10, a connector 11 and a communication interface 12.

[0047] The following is combined with Figure 1 The wireless charging device provided in this application is further described.

[0048] In some embodiments, Figure 1 As shown, the magnetic attraction device 1 is configured as a hollow structure, and the magnetic attraction device 1 may include a magnet module 101 and a magnetic isolation sheet 102 .

[0049] The magnet module 101 is used to provide magnetic attraction to fix the mobile device. The magnet module 101 can be Figure 1 A ring magnet is shown. Compared with magnets of other shapes, the ring magnet can provide a more uniform magnetic field distribution, so that the position of the mobile device can be more accurately located, and the ring magnet can better adapt to the shape and size of the mobile device to achieve more stable wireless charging.

[0050] In addition, the magnet module 101 may also be composed of multiple magnets, or composed of magnets of other shapes, such as rectangular, U-shaped, etc., which is not limited here.

[0051] The magnetic isolation sheet 102 is used to increase the closing effect of the magnetic lines of force of the magnet module 101, which can be Figure 1 The annular magnetic isolation plate shown.

[0052] Furthermore, wireless charging can be achieved through Qi2 magnetic technology. Qi2 magnetic technology is a wireless charging technology that uses the principle of magnetic resonance to achieve wireless charging through magnetic attraction. Compared with traditional electromagnetic induction charging technology, Qi2 magnetic attraction has higher charging efficiency and smaller volume, which can achieve more portable and reliable wireless charging.

[0053] In some embodiments, the transmitting coil 2 can be disposed in the hollow structure of the magnetic attraction device 1. The transmitting coil 2 is usually a ring structure composed of several coils. Each coil is composed of a wire and a magnetic material. When current passes through the wire, a magnetic field is generated. This magnetic field forms a magnetic field area inside the coil. When multiple coils are combined together, a stronger magnetic field can be formed, thereby realizing the emission of the magnetic field.

[0054] The above is a further description of the magnetic attraction device 1 and the transmitting coil 2 .

[0055] In some embodiments, the wireless charging device includes at least one communication chip, and the communication chip can be arranged in the middle of the transmitting coil. This is because the communication distance between the communication chip of the wireless charging device and the chip of the mobile device is usually short, and it is necessary to ensure that they are aligned in relative positions to achieve effective communication. In addition, placing the communication chip in the middle of the coil can reduce interference and loss of communication signals, improve communication quality and stability, and appropriately reduce the size of the wireless charging device, making the wireless charging device more portable.

[0056] Specifically, when the wireless charging device has only one communication chip, the communication chip can be arranged at the center of the ring structure of the transmitting coil 2, such as Figure 1 When the wireless charging device has two or more communication chips, one of the communication chips can be arranged at the center of the ring structure of the transmitting coil 2, such as Figure 1 The communication chip 301 shown in the figure, other communication chips can be set at any position within a preset range around the magnetic attraction device 1, such as Figure 1 The communication chip 302 is shown so that the wireless charging device can effectively communicate with the mobile device based on the communication chip 3.

[0057] Furthermore, in some embodiments, the communication chip 3 can be a millimeter wave communication chip, specifically a 60GHz millimeter wave communication chip. The frequency range of millimeter wave communication is usually between 1-100GHz, and common frequency bands include 28-39GHz, 77-81GHz, etc. Among them, the millimeter wave communication in the 28-39GHz frequency band has a higher transmission rate and a large bandwidth, which can achieve high-speed wireless charging and high-speed data transmission, but the transmission distance is short and the penetration ability is weak; the millimeter wave communication in the 77-81GHz frequency band has a higher transmission power and a longer transmission distance, and the penetration ability is strong, but the transmission rate is low, which is not suitable for high-speed data transmission. The 60GHz millimeter wave communication has the characteristics of high bandwidth, low latency, and strong anti-interference ability, so the communication chip 3 can choose a 60GHz millimeter wave communication chip.

[0058] In other implementations, the communication chip 3 may include multiple millimeter wave communication chips, or may include a millimeter wave communication chip and other types of communication chips, such as a Bluetooth communication chip, a WiFi communication chip, and the like.

[0059] It should be pointed out that the above examples of communication chips are only schematic illustrations. In actual applications, technical personnel in this field can make settings according to specific scenarios, including but not limited to millimeter wave communication chips in other frequency bands and other types of communication chips, which are not limited here.

[0060] The above is a further description of the communication chip 3 .

[0061] In some embodiments, the heat dissipation structure 4 includes Figure 1 The cold end heat dissipation fins 401 , the cold air fan 402 , the hot air fan 403 and the hot end heat dissipation fins 404 are shown.

[0062] TEC5 includes a TEC cold surface and a TEC hot surface, wherein the TEC cold surface can be adjacent to the cold end heat sink fin 401 so that the cold end heat sink fin 401 couples the cold energy of the TEC cold surface; the TEC hot surface can be adjacent to the hot end heat sink fin 404 so that the hot end heat sink fin 404 reduces the temperature of the TEC hot surface.

[0063] Furthermore, if Figure 1 As shown, the right side of the cold end heat sink fin 401 is adjacent to the cold air fan 402, and the bottom of the hot end heat sink fin 404 is adjacent to the hot air fan 403. The cold air fan 402 and the hot air fan 403 provide air volume for the cold end heat sink fin 401 and the hot end heat sink fin 404 respectively.

[0064] In actual applications, the cold air fan 402 can also be set on the left side, above, and below the cold-end cooling fins 401, and the hot air fan 403 can also be set on the left side, right side, and above the hot-end cooling fins 404, as long as the cold air fan 402 and the hot air fan 403 provide air volume for the cold-end cooling fins 401 and the hot-end cooling fins 404 respectively, no limitation is made here.

[0065] In some embodiments, TEC5 is a refrigerator made using the Peltier effect of semiconductor materials. The Peltier effect refers to the phenomenon that when a direct current passes through a couple composed of two semiconductor materials, one end absorbs heat and the other end releases heat. Heavily doped N-type and P-type bismuth telluride are mainly used as semiconductor materials for TEC. The bismuth telluride elements are electrically connected in series and generate heat in parallel. TEC includes some P-type and N-type pairs (groups), which are connected together by electrodes and sandwiched between two ceramic electrodes. When current flows through TEC, the heat generated by the current will be transferred from one side of TEC to the other side, generating a "hot" side and a "cold" side on the TEC. This is the heating and cooling principle of TEC.

[0066] Through the above implementation, the problem that the mobile device often generates heat during charging and cannot continue to charge or transmit data is solved, thereby ensuring a good temperature environment.

[0067] The above is a further description of the heat dissipation structure 4 and TEC 5.

[0068] In some embodiments, the air duct structure 6 may include a vent, a first air duct, and a second air duct.

[0069] There are multiple vents, which are respectively arranged on the surface of the housing 7, such as Figure 1 The vents 601 on the top of the housing 7 and the vents 602 on the side wall are shown, and in addition, the vents on the bottom of the housing (not shown in the figure) may also be included; the first air duct is configured to transfer external air to the cold end heat sink fins 401 via the cold air fan 402, and transfer the cold generated by the cold end heat sink fins 41 to the mobile device; the second air duct is configured to transfer external air to the hot end heat sink fins 404, and transfer the heat generated by the hot end heat sink fins 404 to the external space via the hot air fan 403. The air duct structure 6 and the housing 7 can be fixed by a fixing module 8.

[0070] In some embodiments, see Appendix Figure 2 , Figure 2 2 is a front cross-sectional view of a wireless charging device according to an embodiment of the present application. Figure 2 As shown, after the wireless charging device is powered on, the direction of cold transfer in the first air duct is Figure 2As indicated by the solid arrows, external normal temperature air is transferred from the vent 602 on the side wall of the housing 7 to the cold end heat sink fins 401 via the cold air fan 402, and the cold air is obtained after being cooled by the cold end heat sink fins 401, and is transferred to the mobile device via the vent 601 on the top of the housing 7, that is, external normal temperature air → vent 602 → cold air fan 402 → cold end heat sink fins 401 → vent 601 → mobile device.

[0071] The heat transfer direction in the air duct structure is Figure 2 As shown by the dotted arrow in the middle: external normal temperature air is transferred from the vent 602 on the side wall of the shell 7 to the hot end heat dissipation fins 404, and after the hot end heat dissipation fins are heated up, hot air is obtained and transferred to the hot air fan 403, and finally transferred to the external space through the vent at the bottom of the shell 7, that is, external normal temperature air → vent 602 → hot end heat dissipation fins 404 → hot air fan 403 → vent at the bottom of the shell 7 → external space.

[0072] Among them, the multiple vents, the first air duct and the second air duct of the air duct structure 6 can be made of plastic materials such as PC and PBT. These materials have good mechanical properties and heat resistance, can withstand high temperatures and vibrations, and have good formability and processing properties, which are convenient for manufacturing and processing.

[0073] The above is a further description of the air duct structure 6 , the housing 7 and the fixed module 8 .

[0074] In some embodiments, Figure 1 As shown, the electromagnetic shielding module 9 is adjacent to the magnetic attraction device 1 and the transmitting coil 2 at the top, and adjacent to the heat dissipation structure 4 at the bottom.

[0075] The electromagnetic shielding module 9 can prevent the influence of electromagnetic interference and radio frequency interference on the wireless charging system, specifically by isolating the circuits and components inside the wireless charging device from the external electromagnetic field, reducing the influence of the external electromagnetic field on the wireless charging system, and improving the technology of magnetic induction intensity, thereby improving the charging efficiency.

[0076] Commonly used electromagnetic shielding materials for the electromagnetic shielding module 9 include ferrite, copper foil, conductive foam, etc., which are not limited here.

[0077] In some embodiments, the PCBA circuit board 10 is a circuit board formed by assembling electronic components on a printed circuit board PCB. The PCBA circuit board 10 is used to carry various electronic components, such as integrated circuits, capacitors, resistors, transistors, etc., and connect them to form a complete circuit.

[0078] like Figure 1As shown, the PCBA circuit board 10 is adjacent to the connector 11. The connector 11 is arranged on the surface of the housing 7, usually at the bottom or the side. The connector 11 is mainly used to connect the circuit inside the wireless charging device and the charging base to realize the wireless charging function.

[0079] The communication interface 12 is arranged on the surface of the housing 7, usually on the side or the top, so that the user can connect other devices through the communication interface for data transmission. Among them, the communication interface 12 can be a high-speed communication interface such as USB, Ethernet, DP, HDMI, etc. Among them, the USB interface is a universal external bus interface standard, including different versions such as USB1.1, USB2.0, USB3.0, USB3.1, etc., which are used to connect computers and various external devices; the Ethernet interface is usually an RJ45 interface for connecting computers and other devices; the DP interface is a digital video and audio transmission interface for connecting computers and monitors, projectors and other devices; the HDMI interface is a digital video and audio transmission interface for connecting high-definition televisions, movie players, game consoles and other devices.

[0080] Furthermore, the transmission protocol for data transmission through the above-mentioned communication interface may include USB transmission protocol, Ethernet transmission protocol, DP transmission protocol and HDMI transmission protocol, etc.

[0081] Among them, the USB transmission protocol is a serial bus protocol that defines how devices communicate with the host and how devices communicate with each other. The USB transmission protocol includes four levels: physical layer, data link layer, transport layer and application layer; the Ethernet transmission protocol is a CSMA / CD protocol that defines how to transmit data packets from one computer to another. The Ethernet protocol also defines some standards, such as 10Mbps, 100Mbps, 1Gbps, etc.; the transmission protocol used by the DP transmission protocol is the DisplayPort protocol, which is a digital audio / video interface protocol that defines how to transmit digital audio / video signals to the display. The DisplayPort protocol supports high resolution, high refresh rate and multi-display configuration; the HDMI transmission protocol is a digital video and audio interface protocol that defines how to transmit digital video and audio signals to devices such as TVs, monitors and speakers. The HDMI protocol supports high-definition video, 3D video and audio output.

[0082] It should be pointed out that the above examples of communication interfaces and transmission protocols are only illustrative. In practical applications, those skilled in the art can select and combine them according to specific scenarios and requirements, and no limitation is made here.

[0083] The above is a further description of the PCBA circuit board 10 , the connector 11 and the communication interface 12 .

[0084] It should be pointed out that the above examples of the structure of the wireless charging device are only schematic illustrations. In practical applications, those skilled in the art can make corresponding settings and changes according to specific scenarios and requirements, and no limitation is made here.

[0085] Through the above implementation, a heat dissipation effect with higher efficiency than traditional air cooling can be achieved, ensuring the temperature environment for charging and data transmission of mobile devices, and the magnetic suction device can ensure that the mobile device will not move with the acceleration of the vehicle on the driving device, thereby enhancing the stability of charging and data transmission of the mobile device.

[0086] Furthermore, the present application also provides a communication method based on a wireless charging device. Figure 3 , Figure 3 FIG. 1 is a flow chart of the main steps of a communication method based on a wireless charging device according to an embodiment of the present application. Figure 3 As shown, it mainly includes the following steps S301 to S302.

[0087] Step S301: In response to the connection between the wireless charging device and the mobile device and the driving device, the mobile device sends a communication signal through the wireless charging device;

[0088] Step S302: The driving device receives a communication signal through the wireless charging device and performs a corresponding operation based on the communication signal.

[0089] Specifically, the communication chip of the wireless charging device (such as millimeter wave communication chip, Bluetooth communication chip, etc.) can be connected to the corresponding communication chip of the mobile device to achieve high-bandwidth, low-latency, and interference-free communication between the wireless charging module and the mobile device. At the same time, the communication interface of the wireless charging device can be connected to the USB, Ethernet, DP, HDMI and other high-speed communication interfaces of the driving device to achieve real-time communication between the mobile device and the driving device.

[0090] The communication signal between the mobile device and the driving device includes at least one of a DP signal and a control signal.

[0091] DP signal is the signal transmitted in the DisplayPort interface, including video signal, audio signal and command signal, etc.; control signal refers to the signal used to transmit control information, such as touch screen control information, etc.

[0092] Furthermore, the mobile device and / or driving device can also send communication signals to a target device, such as a vehicle display, a tablet computer, a television, AR glasses, and a VR device, so that the target device performs a corresponding function.

[0093] The following is combined with Figure 4 To Attachment Figure 6The above communication method based on the wireless charging device is further described.

[0094] In some embodiments, see Appendix Figure 4 , Figure 4 FIG. 1 is a schematic diagram of communication based on a wireless charging device according to an embodiment of the present application. Figure 4 As shown, it includes a mobile device, a wireless charging device and a driving device, wherein the wireless charging device is provided with two millimeter wave communication chips, namely a high-speed 60GHz millimeter wave chip and a low-speed 60GHz millimeter wave chip.

[0095] like Figure 4 As shown, in response to the connection between the wireless charging device and the mobile device and the driving device, the mobile device sends a DP signal and a control signal through the wireless charging device, the driving device receives the DP signal and the control signal through the wireless charging device, and performs corresponding operations.

[0096] Specifically, the SOC or AP of the mobile device outputs the DP signal, which is output to the high-speed 60GHz millimeter wave chip that supports high-speed transmission through the internal USB3.x Switch (here x represents the USB3.0 version, according to the latest USB Association naming standard, including USB3.2 Gen1, USB3.2 Gen2, USB3.2 Gen2*2), and sent to the driving device through the wireless charging device. The high-speed 60GHz millimeter wave chip of the driving device serves as the receiving end, transmits the DP signal to the media control center of the vehicle system, and encodes and decodes the DP signal into a USB3.x signal, and then finally transmits it to the SOC or AP of the driving device through the internal USB3.x Controller. After the USB signal is encoded and decoded, it is converted into audio signals, video signals, etc., and finally displayed on the vehicle display through MIPIDSI. Conversely, the driving device can also transmit communication signals to the mobile device through the wireless charging device.
