DETAILED DESCRIPTION

[0033] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

It should be noted that in the embodiments of this application, some existing solutions in the industry such as certain software, components, and models may be mentioned, and they should be considered as exemplary. Their purpose is only to illustrate the feasibility of the implementation of the technical solution of this application, but it does not mean that the applicant has or will necessarily use the solution.

[0036] In order to solve the problems of the prior art, an embodiment of the present application provides a wireless charging method, which can be applied in a scenario where a vehicle is provided with a wireless charging module, and the wireless charging module is used to wirelessly charge a mobile terminal. Figure 1 is a flow chart of a wireless charging method applied to a wireless charging module according to an embodiment of the present invention. Figure 1 As shown, the wireless charging method may include the following steps:

[0037] S110, when the terminal is placed at a position corresponding to the wireless charging module, obtaining an induced electromotive force of a receiving coil of the terminal.

[0038] In this embodiment, the terminal may be a mobile smart device that supports wireless charging, for example, including a mobile phone, a smart watch, a headset, etc.; the position corresponding to the wireless charging module may be a wireless charging panel groove of the wireless charging module, and the wireless charging panel groove may be used to place terminals of various sizes; for example, Figure 2 is a schematic diagram of the structure of the groove of the wireless charging panel according to an embodiment of the present invention. Figure 2As shown, the wireless charging panel groove 201 minimizes the mobile phone placement limit area as much as possible while being compatible with all current large-size mobile phones with wireless charging function. In this way, the placed mobile phone can be prevented from being tilted too much. The wireless charging panel groove 201 can also be set to be tilted upward at an angle of 35 degrees, so that the mobile phone placed on it can naturally slide down to the bottom supporting surface, and at the same time, it can prevent the mobile phone from sliding forward or flying out due to large displacement due to vehicle starting and stopping.

[0039] In this embodiment, when the terminal is placed at a position corresponding to the wireless charging module, the wireless charging module can emit a magnetic field based on a preset frequency, thereby causing the magnetic flux of the receiving coil of the terminal to change, thereby generating the induced electromotive force that needs to be obtained.

[0040] S120, determining the center coincidence rate of the transmitting coil and the receiving coil according to the induced electromotive force and a preset first threshold.

[0041] In this embodiment, the preset first threshold value can be set according to the minimum value of the induced electromotive force that can charge the terminal when the center point of the receiving coil is located on the center line of the transmitting coil in the first direction.

[0042] For example, the calculation formula of the center overlap rate may be P=E1 / E, wherein P is the center overlap rate, E1 is the induced electromotive force, and E is a preset first threshold.

[0043] It can be understood that the center overlap rate can be used to characterize the degree of alignment between the center of the transmitting coil and the center of the receiving coil. The higher the center overlap rate, the higher the energy conversion efficiency of the wireless charging.

[0044] S130, when the center overlap ratio is within the calibration threshold range, controlling the motor to drive the transmitting coil to move to a target position in a first direction, and the center overlap ratio of the target position is greater than a maximum value of the calibration threshold range.

[0045] In this embodiment, the calibration threshold range is used to represent that when the center overlap rate is within this range, the wireless charging module can wirelessly charge the terminal, but the efficiency of wireless charging is low, and the transmitting coil and the receiving coil need to be further aligned to improve the wireless charging efficiency; for example, the calibration threshold range can be [70%, 95%].

[0046] In this embodiment, when the center overlap rate is within the calibration threshold range, the transmitting coil can be driven by controlling the motor to move to the target position in the first direction, so that the transmitting coil and the receiving coil are aligned as much as possible to improve the wireless charging efficiency; wherein, the motor can be a stepper motor, and the stepper motor is controlled by transmitting a pulse signal to realize the motor driving the transmitting coil to move, and the first direction can be the X-axis direction of the preset coordinate system.

[0047] S140, controlling the wireless charging module to wirelessly charge the terminal.

[0048] In this embodiment, when the transmitting coil is at the target position, it can be determined that the transmitting coil of the wireless charging module is aligned with the receiving coil of the terminal in the first direction, and the wireless charging module can be controlled to perform wireless charging on the terminal.

[0049] In an embodiment of the present application, by acquiring the induced electromotive force of the terminal receiving coil and calculating the center overlap rate based on the induced electromotive force, the transmitting coil is moved in the first direction to a target position determined according to the center overlap rate, thereby achieving alignment of the transmitting coil and the receiving coil in the first direction, thereby improving the efficiency of wireless charging of the terminal, and solving the technical problem in the related art that the transmitting coil of the wireless charging module and the receiving coil of the terminal are difficult to align, resulting in low wireless charging efficiency of the terminal.

[0050] In some embodiments, when the center overlap rate is within the calibration threshold range, controlling the motor to drive the transmitting coil to move to the target position in the first direction, and the center overlap rate of the target position is greater than the maximum value of the calibration threshold range, includes:

[0051] A target direction of the transmitting coil moving in the first direction is determined, where the target direction is used to indicate that the center coincidence rate along the direction is continuously increasing.

[0052] The motor is controlled to drive the transmitting coil to move to the target position according to the target direction.

[0053] In this embodiment, the target direction in which the transmitting coil moves in the first direction may be determined by calculating the step effective value.

[0054] For example, Figure 3 is a logic diagram of a motor drive according to an embodiment of the present invention, such as Figure 3 As shown: the wireless charging microcontroller unit can collect the induced electromotive force of the receiving coil of the terminal in real time, including the induced electromotive force E1 corresponding to the initial position of the transmitting coil and the induced electromotive force E2 corresponding to the stepping position of the transmitting coil, and calculate the stepping effective value and the center overlap rate according to the induced electromotive force E1, the induced electromotive force E2 and the preset first threshold.

[0055] The step position is the position after the wireless charging microcontroller controls the stepper motor to drive the transmitting coil to move a preset step toward the side indicated by the first direction. The step effective value ΔE is the difference between E2 and E1, and the preset step can be 1 mm. If ΔE≥0, the side is determined to be the target direction. If ΔE<0, the other side indicated by the first direction is determined to be the target direction.

[0056] The motor is controlled to drive the transmitting coil to move toward the target direction based on a preset step until the center overlap rate is greater than the maximum value of the calibration threshold range, and then the movement stops.

[0057] In this way, by intelligently calculating the effective value of the step and controlling the motor to automatically adjust the position of the transmitting coil, the center overlap rate is ensured to be optimal, thereby improving the efficiency and accuracy of wireless charging.

[0058] In some embodiments, after determining the center coincidence rate of the transmitting coil and the receiving coil according to the induced electromotive force and the preset first threshold, the method further includes:

[0059] When the center overlap rate is greater than the maximum value of the calibration threshold range, the wireless charging module is controlled to perform wireless charging on the terminal.

[0060] In this embodiment, when the center overlap rate is greater than the maximum value of the calibration threshold range, it can be understood that the terminal has been placed in the optimal charging position of the wireless charging module, and therefore the wireless charging module can be controlled to wirelessly charge the terminal.

[0061] In some embodiments, the method further comprises:

[0062] When the center overlap rate is less than the minimum value of the calibration threshold range, adjustment information is sent to the user, where the adjustment information is used to inform the user to adjust the position of the terminal.

[0063] In this embodiment, when the center overlap rate is less than the minimum value of the calibration threshold range, it can be understood that the center coupling degree between the receiving coil of the terminal and the transmitting coil of the wireless charging module is very low, that is, the terminal is not placed in the charging position of the wireless charging module, and the wireless charging module may not be able to effectively charge the terminal. In this case, adjustment information can be sent to the user to inform the user to adjust the position of the terminal.

[0064] For example, Figure 4 is a schematic diagram of a control system according to an embodiment of the present invention. Figure 4 As shown, the control system includes a wireless charging module 402, a smart cockpit domain controller 406 and a central control large screen 407. The wireless charging module 402 includes a wireless charging micro control unit 403, a transmitting coil module 404 (transmitting coil) and a stepper motor module 405 (motor). The user puts the terminal 401 into the wireless charging module 402 for wireless charging. If the terminal 401 cannot be effectively charged, a Can signal can be sent to the user through the controller area network (Controller Area Network, Can) bus. The Can signal can carry notification information to notify the smart cockpit domain controller 406 and the central control large screen 407 to remind the user in text and voice that the terminal 401 is not placed properly and please put it right again.

[0065] In this way, by detecting the center overlap rate and providing real-time feedback of adjustment information, the convenience and efficiency of wireless charging are effectively improved, ensuring that users can accurately place the terminal to maximize the terminal's wireless charging efficiency.

[0066] In some embodiments, the wireless charging module includes a plurality of transmitting coils, and the plurality of transmitting coils are arranged along a second direction, and the second direction is a direction perpendicular to the first direction. Controlling the wireless charging module to wirelessly charge the terminal includes:

[0067] Obtaining the induced electromotive force of the receiving coil of the terminal for each transmitting coil, and obtaining the induced electromotive force corresponding to the multiple transmitting coils;

[0068] According to the induced electromotive force corresponding to the multiple transmitting coils, a working coil that meets the preset conditions is determined from the multiple transmitting coils;

[0069] Control the working coil in the wireless charging module to wirelessly charge the terminal.

[0070] In this embodiment, Figure 5 is a schematic diagram of a coil arrangement according to an embodiment of the present invention. Figure 5 As shown, the first direction can be the X-axis direction of the preset coordinate system, and the second direction can be the Y-axis direction of the preset coordinate system, where the X-axis is perpendicular to the Y-axis; the wireless charging module can include a transmitting coil A501, a transmitting coil B502, and a transmitting coil C503; the transmitting coil A501, the transmitting coil B502, and the transmitting coil C503 can be arranged in combination along the second direction, and the receiving coil 504 and the wireless charging module have been aligned on the X-axis based on the coil center line of the receiving coil 504.

[0071] In this embodiment, the transmitting coil of the wireless charging module has been aligned with the receiving coil in the first direction, and the efficiency of wireless charging of the terminal can be further improved by aligning the transmitting coil of the wireless charging module with the receiving coil of the terminal in the second direction.

[0072] It can be understood that, since the transmitting coil of the wireless charging module is fixedly arranged in the second direction and cannot be moved up and down, the transmitting coil with the highest coupling degree with the receiving coil position can be determined as the working coil;

[0073] The method for determining the working coil can first obtain the induced electromotive force of the receiving coil of the terminal for each transmitting coil, and obtain the induced electromotive force corresponding to the multiple transmitting coils; then, according to the induced electromotive force corresponding to the multiple transmitting coils, determine the working coil that meets the preset conditions from the multiple transmitting coils; wherein the preset condition can be the transmitting coil corresponding to the maximum induced electromotive force.

[0074] In this way, by determining the working coil to wirelessly charge the terminal, the transmitting coil of the wireless charging module and the receiving coil of the terminal are aligned in the second direction, further improving the efficiency of wireless charging of the terminal.

[0075] In order to facilitate understanding of the solutions of the above embodiments, Figure 6 is a schematic cross-sectional structure diagram of a wireless charging module according to an embodiment of the present invention. Figure 6 As shown, the wireless charging module includes a transmitting coil module 404, a wireless charging panel groove 201 and a motor 601. The transmitting coil module 404 may include a transmitting coil A501, a transmitting coil B502, and a transmitting coil C503. The terminal 401 is equipped with a receiving coil 504 inside and is placed in the wireless charging panel groove 201 for charging.
