[0040] In one embodiment, Figure 1 As shown, a vehicle-mounted wireless charger 1 is provided, comprising: a bus transceiver 11 , a microcontroller 12 and an energy storage component 13 .

[0041] The bus transceiver 11 includes a first communication interface 11-1, a second communication interface 11-2 and a power port 11-3, wherein the power port 11-3 is used to receive a power supply signal to power the bus transceiver 11, and the first communication interface 11-1 is used to connect to the vehicle controller 2. The bus transceiver 11 refers to a device or apparatus for receiving and sending data on a data bus.

[0042] The first communication interface 11 - 1 refers to an interface on the bus transceiver 11 , which is specifically used to connect to the vehicle controller 2 , and allows the vehicle controller 2 to communicate with other devices or modules on the bus and send or receive instructions and data.

[0043] The second communication interface 11 - 2 is also an interface on the bus transceiver 11 , which is used to connect to the microcontroller 12 . The second communication interface 11 - 2 allows the microcontroller 12 to communicate with the vehicle controller 2 on the bus to send or receive instructions and data.

[0044] The power port 11-3 is a port on the bus transceiver 11, and is used to receive a power supply signal to provide the required power to the bus transceiver 11. The power supply signal comes from a battery or other power source of the vehicle.

[0045] The microcontroller 12 is connected to the second communication interface 11 - 2 . The microcontroller 12 communicates with the bus transceiver 11 , analyzes the control instructions issued by the vehicle controller 2 according to the received bus data, and executes actions according to the control instructions.

[0046] The first end of the energy storage component 13 is connected to the power port 11-3, and the second end of the energy storage component 13 is grounded. The energy storage component 13 is used to power the bus transceiver 11 when the bus transmission between the microcontroller 12 and the vehicle controller 2 fails. Among them, the energy storage component 13 is an energy storage device, which is usually used to provide a backup power supply in the power system or release the stored energy when needed. In the embodiment of the present application, the energy storage component 13 is used to provide the required power for the bus transceiver 11 when the bus transmission between the microcontroller 12 and the vehicle controller 2 fails, so as to ensure that the bus transceiver 11 works until the bus returns to normal. Through the power port 11-3 of the bus transceiver 11, the energy storage component 13 can receive power from the power port 11-3 when needed and store it. Since the bus transceiver 11 needs a larger working current to ensure that the bus transceiver 11 works until the bus returns to normal when the bus transmission fails, therefore, when the bus transceiver 11 fails, the energy storage component 13 powers the bus transceiver 11 to provide the additional required working current.

[0047] The vehicle controller 2 is a main control unit in the vehicle, responsible for managing and monitoring multiple systems of the vehicle, such as the engine, brakes, steering, etc.

[0048] In this embodiment, an energy storage component 13 is added to the vehicle charger, which can receive power from the power port 11-3 of the bus transceiver 11 and store it when the bus transmission between the microcontroller 12 and the vehicle controller 2 is normal. When the bus transmission between the microcontroller 12 and the vehicle controller 2 fails, the required power is provided to the bus transceiver 11 to ensure that the bus transceiver 11 works until the bus returns to normal, thereby avoiding the problem of the bus transceiver 11 being unable to communicate with the vehicle controller 2 due to power failure.

[0049] In one embodiment, Figure 2 FIG. 1 is a schematic diagram of a structure in which a vehicle-mounted wireless charger charges a device to be charged in one embodiment. Figure 2 As shown, the vehicle-mounted wireless charger 1 further includes: a power conversion component 14 .

[0050] The control end of the power conversion component 14 is connected to the microcontroller 12. The power conversion component 14 is used to receive the vehicle current and convert the vehicle current into power to obtain the charging current, so as to wirelessly charge the charging device 3 based on the magnetic field generated by the charging current, wherein the charging current is an alternating current.

[0051] The power conversion component 14 is used to convert the vehicle current into an AC charging current for wireless charging. The control end of the power conversion component 14 is connected to the microcontroller 12, and the microcontroller 12 can monitor and control the working state of the power conversion component 14 to ensure that it works as expected.

[0052] The on-board current is usually direct current (DC), and its voltage and current depend on the specific configuration of the vehicle. The power conversion component 14 contains some circuits and components that can convert the received on-board DC current into an AC charging current. The AC charging current processed by the power conversion component 14 will be transmitted to a wireless charging transmitter (which may be a coil or other form of electromagnetic transmitter). This transmitter will generate a magnetic field, which can be received by the device to be charged 3 (such as a wireless charging receiver) and convert the magnetic field energy into electrical energy, thereby wirelessly charging the device to be charged 3.

[0053] Specifically, when no charging is required, the microcontroller 12 controls the power conversion component 14 to convert the vehicle current into an AC charging current for wireless charging, and wirelessly charges the device to be charged 3 based on the magnetic field generated by the charging current.

[0054] In this embodiment, the control end of the power conversion component 14 is connected to the microcontroller 12, so that the microcontroller 12 can monitor the working state of the power conversion component 14 in real time, including parameters such as current, voltage, and temperature. Once an abnormal situation is found, the microcontroller 12 can immediately take measures, such as adjusting the working parameters, cutting off the power supply, etc., to protect the power conversion component 14 and the entire system from damage. The microcontroller 12 can accurately control the output of the power conversion component 14 as needed to ensure that the wireless charging process is efficient and stable. For example, it can adjust the size and frequency of the charging current according to the needs of the device to be charged 3 to achieve the best charging effect.

[0055] In one embodiment, Figure 2 As shown, the power conversion assembly 14 further includes: a power converter 14 - 1 , a power converter 14 - 2 and a coil 14 - 3 .

[0056] The power converter 14 - 1 is used to convert the vehicle current to obtain a direct current. The vehicle current is a direct current, and the power converter 14 - 1 converts the vehicle current to obtain a direct current, which means that the power converter 14 - 1 converts the vehicle current to obtain direct currents of different magnitudes.

[0057] In some embodiments, the power converter 14 - 1 may use a power conversion chip to implement the conversion function.

[0058] The first end of the power converter 14-2 is connected to the power converter 14-1, and the control end of the power converter 14-2 serves as the control end of the power conversion component 14. The power converter 14-2 is used to convert direct current into charging current; wherein the charging current is alternating current.

[0059] The coil 14 - 3 is connected to the second end of the power converter 14 - 2 for receiving the charging current to generate a magnetic field based on the charging current.

[0060] In some embodiments, the process of the vehicle-mounted wireless charger charging the device to be charged is as follows: the vehicle wakes up, the vehicle-mounted wireless charger 1 enters a standby state, the microcontroller 12 communicates with the power conversion component 14, and in a normal charging working state, the microcontroller 12 controls the power conversion component 14 to start working, and controls the AC power converted by the power conversion component 14 to be around 5.5V, the microcontroller 12 detects the device to be charged 3 in the vehicle, and after detecting the device to be charged 3, the microcontroller 12 sends a charging request to the device to be charged 3 by wireless means, and after receiving the charging request, the device to be charged 3 feeds back a response message to the microcontroller 12, wherein the response message includes a charging protocol supported by the device to be charged 3, and after receiving the response message, the microcontroller 12 determines whether the charging protocol in the response message is a charging protocol supported by the vehicle-mounted wireless charger 1, and if so, confirms that the device to be charged 3 is a charging-allowed device, and the vehicle-mounted wireless charger 1 enters a charging state, the microcontroller 12 controls the power conversion component 14 to generate a charging current, and generates a magnetic field based on the charging current in the coil 14-3, and charges the device to be charged 3 through the magnetic field. If not, it is determined that the device to be charged 3 is not a device that allows charging, and the vehicle-mounted wireless charger 1 enters a dormant state.

[0061] In this embodiment, through the response information sent by the device to be charged 3, the vehicle-mounted wireless charger can determine whether the device to be charged 3 supports a compatible charging protocol, and only charge the device to be charged 3 that supports the charging protocol, and does not allow charging of devices that do not support the charging protocol, thereby avoiding incompatible charging situations, protecting the safety of the device, and saving energy.

[0062] In one embodiment, Figure 2 As shown, the vehicle-mounted wireless charger 1 further includes: a surge protection component 15 .

[0063] A first end of the surge protection component 15 is connected to the microcontroller 12 , and a second end of the surge protection component 15 is grounded. The surge protection component 15 is used to receive the surge current output by the microcontroller 12 and discharge the surge current to the common ground.

[0064] When the microcontroller 12 detects a surge current and sends it to the surge protection component 15 through the first end of the surge protection component 15, the surge protection component 15 will quickly guide the high-intensity current to the second end of the surge protection component 15 and safely discharge it to the public ground through the ground connection. In this way, the surge protection component 15 acts as a "discharge valve" to protect the microcontroller 12 and other related circuits from damage by the surge current. In this embodiment, the first end of the surge protection component 15 is connected to the power supply end of the microcontroller 12.

[0065] In some embodiments, Figure 3 1 is a circuit diagram of a surge protection component in an embodiment. The surge protection component 15 includes a transient suppression diode TVS, wherein the anode of the transient suppression diode TVS is connected to the microcontroller, and the cathode of the transient suppression diode TVS is grounded.

[0066] Among them, the transient suppression diode TVS is a diode designed to absorb and clamp the transient voltage of the microcontroller 12. When a surge current or transient high voltage appears in the circuit, the transient suppression diode TVS will quickly turn on to clamp the excessive voltage at a safe level, and the surge current will safely flow to the ground through the TVS, thereby protecting the microcontroller and other circuit components from damage. In this embodiment, the anode of the transient suppression diode TVS is connected to the power supply terminal of the microcontroller.

[0067] In this embodiment, a surge protection component 15 is provided in the vehicle-mounted wireless charger 1, and the surge protection component 15 absorbs and clamps the surge current or transient high voltage of the microcontroller 12, so as to avoid the problem that the surge current generated by the microcontroller 12 when the car is started impacts the microcontroller 12 and causes the microcontroller 12 to fail to work normally.

[0068] In one embodiment, Figure 2 As shown, the vehicle-mounted wireless charger 1 further includes: a circuit board 16 and a heat dissipation component 17 .

[0069] The circuit board 16 is used to load the electronic components of the vehicle-mounted wireless charger 1.

[0070] The heat dissipation component 17 is located at one side of the circuit board 16 . The control end of the heat dissipation component 17 is connected to the microcontroller 12 . The heat dissipation component 17 is used to dissipate heat for the circuit board 16 . Figure 4 FIG. 1 is an exploded view of a vehicle-mounted wireless charger in one embodiment. Figure 4 As shown, the vehicle-mounted wireless charger 1 further includes an upper shell 18 and a lower shell 19, the heat dissipation component 17 is located on one side of the circuit board 16, and the coil 14-3 is located on the other side of the circuit board 16. In this embodiment, Figure 4As shown, the circuit board 16 also includes a plurality of circuit structures 16-1 (MCU control circuit, power conversion circuit, power conversion circuit from left to right) and terminal connectors 16-2, wherein the MCU control circuit includes a microcontroller 12, the power conversion circuit includes a power supply component 121, and the power conversion circuit includes a power converter 14-2. The terminal connector 16-2 is an electrical connector, also known as a terminal block or a terminal block. It is made of insulating material and has a series of metal terminals inside for connecting wires or cables to other components in the circuit.

[0071] In some embodiments, the heat dissipation component 17 may be a heat dissipation fan, a heat sink, a heat pipe, etc. In this embodiment, the heat dissipation component 17 is a heat dissipation fan.

[0072] In this embodiment, a heat dissipation component 17 is provided in the vehicle-mounted wireless charger 1. The heat dissipation component 17 is used to dissipate heat from the circuit board 16, thereby ensuring that the temperature of the power components on the circuit board 16 is within the allowable operating temperature range of the components when working at full load.

[0073] In one embodiment, Figure 2 As shown, the vehicle-mounted wireless charger 1 further includes: a charging indicator light 120 .

[0074] The control end of the charging indicator light 120 is connected to the microcontroller 12 ; the charging indicator light 120 is used to display the charging status of the vehicle-mounted wireless charger 1 .

[0075] When the vehicle-mounted wireless charger 1 is charging, the charging indicator light 120 is on, and when the vehicle-mounted wireless charger is in an idle state, the charging indicator light 120 is off. The charging state of the vehicle-mounted wireless charger 1 can be determined by the state of the charging indicator light 120. The control end of the charging indicator light 120 is connected to the microcontroller 12, and the charging indicator light 120 controls the state of the charging indicator light 120 according to the control instruction issued by the microcontroller 12. In this embodiment, the charging indicator light 120 is installed at a position such as Figure 4 shown.

[0076] In one embodiment, Figure 2 As shown, the vehicle wireless charger 1 also includes a power supply component 121, and the voltage component 121 is used to receive the vehicle current and convert the vehicle current into different working currents, providing working current for components such as the microcontroller 12, the heat dissipation component 17 and the charging indicator light 120.

[0077] In this embodiment, the charging indicator light 120 is provided in the vehicle-mounted wireless charger 1 to directly display the charging status of the vehicle-mounted wireless charger 1 , so that the user can intuitively understand the progress of charging.

The energy storage capacitor can recover and store part of the electric energy during the charging and discharging process, thereby improving the energy efficiency of the entire circuit. When the bus transmission between the microcontroller 12 and the vehicle controller 2 fails, the bus transceiver 11 is powered to ensure that the bus transceiver 11 works until the bus returns to normal.

[0080] In this embodiment, the energy storage capacitor can absorb and release electric energy to smooth the fluctuation of the power supply voltage. When the bus transmission between the microcontroller 12 and the vehicle controller 2 fails, the energy storage capacitor can provide a stable voltage output, and the energy storage capacitor has the characteristics of fast charging and discharging, and can store and release a large amount of electric energy in a short time.

In addition, the metal shielding heat sink 122 has the function of shielding electromagnetic interference signals. Therefore, it can protect the internal circuit of the vehicle wireless charger 1 from being interfered by external electromagnetic signals and reduce electromagnetic interference to external automotive electronic components.
