[0013] Figure 2 It is a working flow chart of the vehicle-mounted integrated unit of the present invention;

[0014] Figure 3 It is a schematic diagram of the identification module in the vehicle-mounted integrated unit of the present invention. DETAILED DESCRIPTION

[0015] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0016] A vehicle-mounted integrated unit, see Figure 1 and Figure 2 , including an identification module 1, a wireless charging device 2 and a control unit 3.

[0017] The wireless charging device 2 is configured to charge a mobile phone through a wireless charging standard. The wireless charging device 2 has a power transmitting coil and can perform wireless charging when matched with a mobile phone (or other device to be charged) with a wireless charging function.

[0018] The identification module 1 is configured to communicate with the connected mobile phone and can identify the digital key carried on the mobile phone. The identification module 1 includes an antenna radiator 11 and an antenna PCB board 12, which are used to realize the functions of sending and receiving communication signals and identifying the digital key. The identification module 1 can analyze the digital key information on the connected mobile phone, and when a valid digital key is identified, feedback the type of the digital key to the control unit 3.

[0019] "Connected mobile phone" refers to a mobile phone that is connected to the identification module 1 for communication, that is, a mobile phone that has a digital key integrated in it and is successfully identified by the identification module 1. "Valid digital key" means that the information of the digital key can be effectively identified by the identification module 1, for example, the information provided by the digital key corresponding to the vehicle can be effectively identified and used to start the vehicle. In addition, more information can be included, for example, the digital key information includes driver habit information, mobile phone wireless charging information, etc. Each information has different categories. After the identification module 1 identifies different information, it feeds back to the control unit 3, so that the control unit 3 performs corresponding operations according to the information.

[0020] For example, if the digital key of the mobile phone integrates the information of unlocking the vehicle, the control unit 3 can unlock the vehicle or start the vehicle. Unlocking here means that the vehicle can be powered on, but there is no sway, and starting the vehicle means that the vehicle can be allowed to shift gears.

[0021] If the digital key of the mobile phone does not integrate the information for unlocking the vehicle (such as the mobile phone of a person other than the owner), but can integrate the information of charging demand, then the control unit 3 may not start the vehicle, but can control the wireless charging device to work and charge the mobile phone according to the charging demand.

[0022] The digital key of the mobile phone integrates the information for unlocking the vehicle and the driving habit information. The control unit 3 can adjust the driving habits, such as adjusting the seat position, adjusting the rearview mirror angle, adjusting the steering wheel height, etc.

[0023] The wireless charging device is configured to adapt according to the wireless charging standard of the mobile phone; the wireless charging standard of the mobile phone is integrated into the digital key information, recognized by the control unit 3, and fed back to the control unit 3.

[0024] The control unit 3 is configured to automatically adjust the charging power or charging mode according to the wireless charging capability of the connected mobile phone; the wireless charging capability information of the mobile phone is integrated into the digital key information, recognized by the control unit 3, and fed back to the control unit.

[0025] The identification module 1 is configured to communicate securely with the mobile phone using an encryption protocol to ensure the secure transmission and storage of digital key information.

[0026] The identification module 1 is configured to record and store historical digital key usage to provide security audit or user behavior analysis.

[0027] The wireless charging device is configured to support simultaneous charging of multiple devices and adjust charging priority through dynamic power allocation to meet the charging needs of multiple devices in the vehicle.

[0028] Furthermore, regarding the setting method of the identification module 1, the basic requirement is to provide a stable and uniform electromagnetic field so that the "swipe card" action is smooth and the recognition rate is high. Here, "swipe card" refers to the process of identifying the digital key. Because the digital key appeared in the form of a card in the early days, "swipe card" is used. It is not limited to the form of a "card" here. In addition, it is also necessary to ensure that the electromagnetic field of the identification module 1 does not affect the operation of the charging unit.

[0029] To meet the above requirements, see Figure 3 , the identification module 1 includes: an antenna radiator 11 and an antenna PCB board 12, the antenna radiator 11 is on the antenna PCB board 12, and the routing method is clockwise from the inside to the outside. Here, it is generally implemented by printed routing, and the spacing between adjacent routings is greater than 5mm; the antenna radiator 11 is coiled in a square shape, and the corners are right-angled corners; there is a blank area at the center of the antenna radiator 11. When the number of antenna radiators 11 is greater than or equal to 2, the distance between two adjacent antenna radiators 11 is less than or equal to 1mm. The limitation is that there are two or three antenna radiators 11. When there is only one antenna radiator 11, this limitation does not exist. When there are two or more antenna radiators 11, the size and routing direction of each antenna radiator 11 are the same.

[0030] The outer side of the antenna radiator 11 is 5mm±2mm away from the frame of the antenna PCB board 12. If there is only one antenna radiator 11, it means that the outermost circle of the only antenna radiator 11 is 5mm±2mm away from the frame of the antenna PCB board 12. When there are multiple antenna radiators 11, it means that the distance from the outer circle of the antenna radiator 11 closest to the frame of the antenna PCB board 12 to the frame is 5mm±2mm. For example, when there are three antenna radiators 11, they are placed in parallel and have the same distance from one of the frames of the antenna PCB board 12, then they all need to meet the 5mm±2mm requirement.

[0031] Preferably, there are two antenna radiators 11, and they are arranged side by side on the left and right. The antenna PCB board 12 is rectangular, and the distance between the upper and lower frames of the two antenna radiators 11 and the antenna PCB board 12 is 5mm±2mm; the distance between the left antenna radiator 11 and the left frame of the antenna PCB board 12 is 5mm±2mm; the distance between the right antenna radiator 11 and the right frame of the antenna PCB board 12 is 5mm±2mm.

[0032] The antenna radiator 11 has at least one layer of routing, preferably 2-4 layers, which can be on the same side of the PCB antenna board 2 or can be printed on both sides.

[0033] In one embodiment, the antenna radiator 11 is printed on both the upper and lower surfaces of the PCB board 2, that is, its routing is realized by printing routing. For the convenience of description, the antenna radiator 11 printed on both sides is called the upper radiator and the lower radiator, and the position of the upper radiator routing corresponds to the gap position between the lower radiator routing.

[0034] That is, the upper radiator and the lower radiator are not completely corresponding, but staggered corresponding, where the staggered correspondence means that the routing and the gap correspond to achieve the staggered routing on both sides. In this way, the magnetic field radiation can be more uniform.

[0035] Preferably, at least the lower radiator is covered with a protective layer, and the outer surface of the protective layer covering the lower radiator is covered with a shielding coating.

[0036] When the antenna radiator 11 is coiled, a give-way inclined portion 11 is formed to avoid line overlap, and the inclination angle of the give-way inclined portion 11 is 45°±10°. The starting part of the antenna radiator 11 is inside the give-way inclined portion 11, and the ending part of the antenna radiator 11 is outside the give-way inclined portion 11. The operating frequency of the antenna radiator 11 is 13.56MHz. The operating frequency of the charging part is about 100KHz.

[0037] In order to realize wireless charging, a power transmitting coil is also required. The power transmitting coil is arranged on the bottom surface of the antenna PCB board 12, and the central area of ​​the power transmitting coil is in the blank area of ​​the antenna radiator 11, so that the shielding of the power transmitting coil is minimized and the two do not interfere with each other.

[0038] An innovative on-board charging module that realizes intelligence, safety and convenience in vehicles. By integrating wireless charging and digital key functions, the module not only improves the user experience, but also enhances the overall safety of the vehicle. Encrypted communication ensures the secure transmission of digital key information. Records and stores historical digital key usage, providing security audits and user behavior analysis. By integrating wireless charging and digital keys, the communication information required for wireless charging can also be provided by the digital key, reducing the use of one communication device, reducing costs, and avoiding interference from multiple communications.

[0039] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings.
