[0051] For the purpose of making the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0052] In one aspect, in combination with Figure 1 and Figure 2 As shown in the drawings, the embodiment provides a vehicle-mounted charging system 100, which is suitable for charging terminal devices 200 in a vehicle space 300.

[0053] The vehicle-mounted charging system 100 comprises a charging control module 1 and an execution module 2; the charging control module 1 is used for determining the power information of a vehicle power supply 400, the quantity information of the terminal devices 200, and the power information of the terminal devices 200; the charging control module 1 is electrically connected with the execution module 2, and the charging control module 1 is used for issuing a charging instruction to the execution module 2 when the power of the vehicle power supply 400 is higher than a first set value, the quantity of the terminal devices 200 is greater than or equal to 1, and the power of the terminal devices 200 is lower than a second set value.

[0054] The execution module 2 comprises an electric energy transmitting end 21 and an electric energy receiving end 22; the electric energy transmitting end 21 is electrically connected with the vehicle power supply 400, and the electric energy receiving end 22 is electrically connected with the terminal devices 200; the execution module 2 is used for charging the terminal devices 200 through the electric energy transmitting end 21 and the electric energy receiving end 22 after receiving the charging instruction.

[0055] The vehicle-mounted charging system 100 of the present application is arranged in the vehicle interior and can charge the terminal device 200 in the vehicle space 300, and comprises a charging control module 1 and an execution module 2. The charging control module 1 determines the power information of the vehicle power supply 400, the number information of the terminal device 200 and the power information thereof. When the power of the vehicle power supply 400 is sufficient, the number of the terminal device 200 is greater than or equal to 1, and the power of the terminal device 200 is insufficient and in the state of needing charging, the execution module 2 is started. The power emission end 21 of the execution module 2 obtains power from the vehicle power supply 400. The power emission end 21 is coupled with the power receiving end 22 in the air. By using the working principle of electricity generating magnetism and magnetism generating electricity, the power receiving end 22 delivers power to the terminal device 200, thereby completing the charging of the terminal device 200 in the air. The terminal device 200 in the vehicle space 300 at any position and in any use state can be charged without contact. Moreover, multiple terminal devices 200 in the vehicle space 300 can be charged at the same time. The convenience and speed of charging the terminal device 200 by the vehicle-mounted system are greatly improved, and the user can have a better and more comfortable driving experience.

[0056] In the present embodiment, the vehicle space 300 refers to the interior space of the vehicle, which includes but is not limited to the passenger cabin, the cargo cabin, the trunk and the engine compartment. Any space region in which the terminal device 200 powered by the battery needs to be arranged can be regarded as the vehicle space 300 of the present embodiment.

[0057] In the present embodiment, the power emission end 21 and the power receiving end 22 realize the transmission of power in the air by using the infinite radio frequency technology. In operation, the power emission end 21 converts power into a radio frequency signal of a certain frequency. When the power receiving end 22 enters the working area of the power emission end 21, an induced current is generated, and the power is stored in the terminal device 200 by using the induced current.

[0058] In some possible implementations, the power emission end 21 can emit the radio frequency signal only in a specific direction, i.e. the direction of the terminal device 200 needing charging, so as to improve the strength of the radio frequency signal received by the power receiving end 22, and the power receiving end 22 can output a greater induced current, thereby improving the power of the charging in the air.

[0059] Alternatively, the power emission end 21 can emit the radio frequency signal in multiple specific directions at the same time, thereby realizing the charging of the terminal device 200 in multiple different positions in the air.

[0060] The radio frequency signal emission direction of the power emission end 21 can be fixed, for example, the radio frequency signal emission direction is directed to the position of the steering wheel, and the terminal device 200 placed in front of the driver can be charged in the air. For another example, the radio frequency signal emission direction is directed to the space above the co-driver seat, and when the passenger of the co-driver seat holds the terminal device 200, the terminal device 200 can be just in the radio frequency signal emission direction. Similarly, the radio frequency signal emission direction is directed to the space above the rear seat, and the terminal device 200 held by the passenger of the rear seat can be charged in the air. For another example, the radio frequency signal emission direction is directed to the area of the inside rearview mirror, and the auxiliary device such as the dashcam attached to or built in the inside rearview mirror can be charged in the air.

[0061] Optionally, the radio frequency signal emission direction of the power emission end 21 can be configured and selected by the charging control module 1, for example, the radio frequency signal is emitted only to the space above the co-driver seat, or the radio frequency signal is emitted to the space above the co-driver seat and the area of the inside rearview mirror at the same time.

[0062] Optionally, the power emission end 21 comprises a directional antenna. The directional antenna refers to an antenna that emits electromagnetic waves particularly strong in one or several specific directions, and emits electromagnetic waves zero or extremely small in other directions. The directional antenna can increase the effective utilization rate of the radiation power and enhance the signal strength.

[0063] Optionally, the power emission end 21 comprises a phased array antenna. The phased array antenna can change the direction of the radiation unit by controlling the phase of the feed, so that the beam is always directed to the power receiving end 22, and the direction of the beam can be adjusted according to the position of the power receiving end 22.

[0064] In some possible implementations, the vehicle power source 400 is a vehicle storage battery. The first set value is 40%-70%. For example, the first set value is 50%, and the charging control module 1 will only start the charging of the terminal device 200 in the air when the power of the vehicle power source 400 is higher than 50%, otherwise it will not start, so as to prevent the power of the vehicle power source 400 from being too low, which affects the normal start of the vehicle or the normal use of other necessary devices (such as the vehicle light system, the vehicle system, etc.) of the vehicle.

[0065] In some embodiments, the power receiver 22 is located within the terminal device 200 or electrically connected to the charging interface of the terminal device 200. The power receiver 22 in this embodiment can take various forms; it can be integrated inside the terminal device 200 or integrated with other antennas of the terminal device 200. Alternatively, the power receiver 22 can be designed as a small and lightweight accessory that plugs into the charging interface of the terminal device 200 without affecting the normal use of the terminal device 200.

[0066] In some possible implementations, the charging interface of the terminal device 200 includes, but is not limited to, USB interface, Type-C interface, and Lightning interface, etc.

[0067] Combination Figure 3 As shown, in some embodiments, the charging control module 1 is communicatively connected to the vehicle's body control module (BCM), and the body control module 500 sends the power information of the vehicle's power supply 400 to the charging control module 1.

[0068] The Body Controller 500, also known as the body computer, is an electronic control unit (ECU) used in automotive engineering to control the electrical systems of the vehicle body. It is the core controller of a car.

[0069] The vehicle body controller 500 needs to constantly monitor the vehicle's status, which requires collecting various vehicle detection parameters, including but not limited to the vehicle power supply 400's charge level, vehicle speed, fuel level, and coolant level. By connecting the charging control module 1 to the vehicle body controller 500 via telecommunications, the charging control module 1 can directly obtain the vehicle power supply 400's charge level from the vehicle body controller 500, eliminating the need for the charging control module 1 to measure it itself. This improves the charging control module 1's efficiency and enhances the vehicle's system integration.

[0070] Combination Figure 4 As shown, in some embodiments, the vehicle power supply 400 includes a normally open power supply 4001 and a switching power supply 4002; the on-board charging system 100 includes a first charging module and a second charging module. In the power supply mode of the normally open power supply 4001, the power transmitting end 21 is electrically connected to the normally open power supply 4001. In the mode of the second charging module, the power transmitting end 21 is electrically connected to the switching power supply 4002.

[0071] The vehicle-mounted charging system 100 of the embodiment, taking into account the structural characteristics of the electrical system of the vehicle in the related art, is designed with two power supply modules. In the first charging mode, the power emission end 21 is electrically connected with the always-on power supply 4001 of the vehicle, and in the second charging mode, the power emission end 21 is electrically connected with the switch power supply 4002 of the vehicle.

[0072] In some possible implementations, the always-on power supply 4001 is a KL30 power supply, and the switch power supply 4002 is a KL15 power supply. The KL30 power supply and the KL15 power supply are the two most common power supply lines in the electrical system of an automobile. The KL30 is an always-on power supply, which is always connected to a battery and is not affected by the key switch of the vehicle, thereby ensuring that the vehicle always has a power supply. The KL15, also known as a cut-off power supply, is connected to the ignition switch, and only has power when the ignition switch is turned on. Thus, in the first charging mode, the vehicle can charge the terminal device 200 in the air without turning on the ignition switch (or the key switch); and in the second charging mode, the vehicle needs to turn on the ignition switch (or the key switch) to charge the terminal device 200 in the air.

[0073] Exemplarily, in the first charging mode, the charging control module 1 is electrically connected with the vehicle door lock system. When the vehicle door lock system outputs an unlocking signal, the charging control module 1 is activated, and the charging control module 1 performs the work of determining the power information of the vehicle power supply 400, the quantity information of the terminal device 200, and the power information of the terminal device 200.

[0074] In combination Figure 5 As shown in the figure, in some embodiments, the vehicle-mounted charging system 100 further includes a communication module 4, which is electrically connected with the charging control module 1 and wirelessly connected with the terminal device 200. The communication module 4 is configured to determine the quantity information of the terminal device 200 and the power information of the terminal device 200, and send the quantity information of the terminal device 200 and the power information of the terminal device 200 to the charging control module 1.

[0075] In the embodiment, the communication module 4 connects the communication system of the terminal device 200 with the signal of the vehicle-mounted charging system 100. The communication system of the terminal device 200 can be a WIFI system, a Bluetooth system, or an NFC (Near Field Communication) system.

[0076] In combination Figure 5As shown, in some embodiments, the vehicle-mounted charging system 100 further comprises a vehicle connection module 5, which is electrically connected with the charging control module 1; the vehicle connection module 5 is used for manually setting charging parameters by a user, and sending the charging parameters to the charging control module 1, the charging parameters including one or more of the following: charging mode, number of terminal devices 200 to be charged, charging power, charging power, and charging current.

[0077] The vehicle-mounted charging system 100 of the embodiment can realize human-computer interaction by using the vehicle connection module 5. By setting the charging parameters and other parameter settings by using the vehicle connection module 5, the vehicle-mounted charging system 100 has more humanized settings and selections, and the human-computer interaction experience is more reasonable and humanized.

[0078] In combination Figure 5 As shown, in some embodiments, the vehicle connection module 5 is integrated into a vehicle machine system 600 or a display system of the vehicle.

[0079] The vehicle machine is also known as a car information entertainment system, which is a device installed in the vehicle. Its main function is to provide information and entertainment services to enhance the fun of driving and improve safety. The vehicle machine can communicate and exchange information with other vehicles or the outside world, supporting a variety of functions, including but not limited to: audio playback, navigation system, vehicle information display, vehicle networking connection, etc.

[0080] The installation position of the vehicle machine is usually on the center console, so that the driver can conveniently operate and use it. With the development of technology, modern vehicle machines have gone beyond traditional cassette players or radios, and have integrated more functions and modules, such as reversing image, audio and video entertainment system, and vehicle control functions.

[0081] Exemplarily, the display system includes at least one display screen, which includes any one of a plasma display panel (PDP), a vacuum fluorescent display (VFD), a field emission display (FED), a light emitting diode (LED), an organic light emitting diode (OLED), a liquid crystal display (LCD), and a micro-electromechanical system display (DMD), etc.

[0082] In combination Figure 5As shown, in some embodiments, the vehicle-mounted charging system 100 further comprises a temperature protection module 6 connected with the charging control module 1 and the execution module 2 respectively, and the temperature protection module 6 is used for over-temperature protection of the charging control module 1 and the execution module 2.

[0083] The temperature protection module 6 can protect the temperature of the charging control module 1 and the execution module 2 in the vehicle-mounted charging module and the power emission end 21, and also consider the heat dissipation control. The temperature protection module 6 comprises heat dissipation fins and heat dissipation fans, water-cooled heat dissipation and other heat dissipation modes. Optionally, the temperature protection module 6 comprises a temperature sensor and a control unit. The temperature sensor in the temperature protection module 6 sends the temperature value to the control unit after checking the temperature value, and the control unit judges after receiving the temperature value. When the temperature value is higher than the limit value set in the control unit, the control unit controls the fan blowing, cooling water circulation and other ways to dissipate heat for the high-temperature components such as the charging control module 1 or the power emission end 21.

[0084] In some possible implementations, the charging control module 1 is also provided with an over-current protection unit and an electrostatic protection unit.

[0085] The vehicle-mounted charging system 100 provided by the application has the following working process:

[0086] In the first charging mode, the normally open power supply 4001 is used for power supply, after the door lock system is unlocked, the unlocking signal, the battery sensor sends the power signal of the vehicle power supply 400 and the setting of the charging parameters of the vehicle-mounted module 5 to the vehicle body controller 500, and the vehicle body controller 500 transmits the power signal of the vehicle power supply 400 to the charging control module 1 through the WIFI / Bluetooth / NFC / CAN / LIN / Internet network system of the vehicle. According to the setting limit, when the power of the vehicle power supply 400 is higher than the first set value, it indicates that the vehicle-mounted charging system 100 has a charging state, and the vehicle-mounted charging system 100 opens the communication module 4. When the communication module 4 receives the signal of the terminal device 200, the charging control module 1 activates the power emission end 21 of the vehicle-mounted charging system 100 to perform the charging of the terminal device 200 such as mobile phone or vehicle-mounted electrical appliance. When the power of the vehicle power supply 400 is lower than the first set value, the vehicle-mounted charging system 100 sends warning information to the terminal device 200. When the temperature of the vehicle-mounted charging system 100 is higher than the control limit value, the temperature protection module 6 is started to work to cool the vehicle-mounted charging system 100.

[0087] In the second charging mode, the switch power supply 4002 is used for power supply. First, the switching state of the KL15 power supply is detected. The power supply signal of the battery sensor, the power signal of the vehicle power supply 400, and the setting of the charging parameters of the vehicle module 5 are sent to the vehicle controller 500. The vehicle controller 500 transmits the power signal of the vehicle power supply 400 to the charging control module 1 through the WIFI / Bluetooth / NFC / CAN / LIN / Internet network system. According to the setting, when the power of the vehicle power supply 400 is higher than the first set value, it indicates that the vehicle charging system 100 has a charging state. The communication module 4 is opened. When the communication module 4 receives the signal of the terminal device 200, the charging control module 1 activates the power transmission end 21 of the vehicle charging system 100 to charge the terminal device 200 such as a mobile phone or a vehicle electrical appliance. When the power of the vehicle power supply 400 is lower than the first set value, the vehicle charging system 100 sends a warning information to the terminal device 200. When the temperature of the vehicle charging system 100 is higher than the control limit value, the temperature protection module 6 is started to cool the vehicle charging system 100.

[0088] On the other hand, in combination with Figure 6 and Figure 7 It is shown that the embodiment provides a charging method suitable for using the vehicle charging system 100 to charge the terminal device 200 in the vehicle space 300.

[0089] The charging method comprises:

[0090] Step S1, the charging control module 1 determines the power information of the vehicle power supply 400, the quantity information of the terminal device 200, and the power information of the terminal device 200.

[0091] Step S2, when the power of the vehicle power supply 400 is higher than the first set value, the number of terminal devices 200 is greater than or equal to 1, and the power of the terminal device 200 is lower than the second set value, the charging control module 1 sends a charging instruction.

[0092] Step S3, the execution module 2 receives the charging instruction, the power transmission end 21 is connected with the vehicle power supply 400, the power transmission end 21 is coupled with the power receiving end 22, and the terminal device 200 electrically connected with the power receiving end 22 is charged.

[0093] The charging method of the embodiment can realize the charging of one or more terminal devices 200 in the vehicle space 300, without affecting the normal use of the terminal device 200, greatly improving the convenience and speed of the charging of the terminal device 200 by the vehicle system, and bringing better and more comfortable driving experience to the user.

[0094] In some possible implementations, step S1 is preceded by:

[0095] In step S01, the vehicle controller 500 sends the power information of the vehicle power supply 400 to the charging control module 1. And / or in step S02, the communication module 4 determines the quantity information and power information of the terminal devices 200, and sends the quantity information and power information of the terminal devices 200 to the charging control module 1.
