Description

Technical Field

[0001] The present application relates to wireless charging positioning, and in particular to a wireless charging positioning method and system based on multiple charging modes. Background Art

[0002] The widespread adoption of wireless charging technology has greatly improved the convenience of recharging electronic devices, freeing users from the constraints of traditional wired charging. However, with technological advancements and diversified market demands, the field of wireless charging has also evolved into different technical paths, with non-magnetic and magnetic wireless charging being the most prominent.

[0003] Non-magnetic charging relies on effective coupling between the receiving coil (RX) of the device being charged (e.g., a mobile phone) and the transmitting coil (TX) of the charger, while magnetic charging uses magnetism to achieve precise alignment and secure attachment. While both have their advantages, achieving both charging modes with a single device, adapting to a wide range of user devices while ensuring a high-quality user experience, remains a significant challenge.

[0004] Specifically, the magnetic transmitting coil is surrounded by magnets. Based on the working principle of wireless charging (the principle of electromagnetic induction), the charging induction range of the magnetic transmitting coil is smaller than that of the non-magnetic transmitting coil. The optimal combination requires the presence of magnets around the receiving coil of the device to be charged. This physically ensures optimal charging coupling and better performance. In addition, because the magnetic transmitting coil and receiving coil must use a handshake protocol during wireless charging, when the charger is in the non-magnetic coil charging state and the device to be charged is in the magnetic coil charging state, the charger's charging output power will be limited, resulting in low charging efficiency or even unusable charging.

[0005] Therefore, how to achieve multi-mode charging of a single device to improve the versatility of the charger is an urgent problem that needs to be solved. Summary of the Invention

[0026] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the exemplary embodiments described are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described herein.

[0027] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "a" should not be understood as limiting the number. "Multiple" means greater than or equal to two.

[0028] Although ordinal numbers such as "first," "second," and the like will be used to describe various components, these are not intended to limit those components. The terms are used solely to distinguish one component from another. For example, a first component could be referred to as a second component, and similarly, a second component could be referred to as a first component without departing from the teachings of the present disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0029] The terms used herein are for the purpose of describing various embodiments only and are not intended to be limiting. As used herein, the singular is intended to include the plural, unless the context clearly indicates otherwise. It will also be understood that the terms "including" and / or "having" when used in this specification specify the presence of a stated feature, number, operation, component, element, or combination thereof, and do not preclude the presence or addition of one or more other features, numbers, operations, components, elements, or combinations thereof.

[0030] Accordingly, if Figure 1 As shown, the wireless charging positioning method based on multiple charging modes according to the embodiment of the present application is explained. Figure 1 As shown, the wireless charging positioning method based on multiple charging modes is used for wireless charging between a charger and a device to be charged, wherein the charger includes a magnetic transmitting coil and a non-magnetic transmitting coil, including the steps of: S110: detecting whether a preset condition is met within a preset time window through the magnetic transmitting coil of the charger; S120, in response to not meeting the preset condition, switching the charging mode to the non-magnetic charging mode.

[0031] It is worth mentioning that in this application, a priority is set between the non-magnetic charging mode and the magnetic charging mode to achieve orderly charging. Furthermore, considering that if the receiving coil of the device to be charged is a magnetic receiving coil, it can be magnetically attracted to the non-magnetic transmitting coil of the charger when placed near the charger, and the position can be automatically verified, the charging efficiency is high, and when the charger is in the non-magnetic coil charging state and the device to be charged is in the magnetic coil charging state, the charging output power of the charger will be limited, resulting in low charging efficiency or even unusable. This application is designed to first verify the magnetic charging mode. If magnetic charging is difficult, switch to the non-magnetic charging mode.

[0032] Accordingly, in step S110, the charger's magnetic transmitting coil detects whether a preset condition is met within a preset time window. Specifically, the preset time window is set based on demand. In one embodiment of the present application, the preset time window is 3 seconds. It should be understood that in other embodiments of the present application, the preset time window may be other values, for example, 1 second, 4 seconds, 5 seconds, etc.

[0033] The preset conditions are that the charger's Q value remains unchanged or that the receiving coil and the magnetic transmitting coil are paired. Q value refers to the quality factor. If the Q value remains unchanged within the preset time window, it means that there is no mobile phone or other object on the charger that could cause a change in the magnetic transmitting coil's magnetic field. Pairing of the receiving coil and the magnetic transmitting coil is primarily accomplished according to a communication protocol.

[0034] In response to a change in the Q value of the charger and the completion of pairing of the receiving coil and the magnetic transmitting coil, the charging mode is controlled to be a magnetic charging mode.

[0035] In response to a change in the Q value of the charger and the receiving coil and the magnetic transmitting coil not being paired, the charging mode is switched to a non-magnetic charging mode.

[0036] Accordingly, in step S120, in response to not meeting the preset conditions, the charging mode is switched to the non-magnetic charging mode. Specifically, in the embodiment of the present application, the non-magnetic coil is designed to be position-adjustable. During the process of switching the charging mode to the non-magnetic charging mode, if the non-magnetic transmitting coil is not located at a position that matches the device to be charged, the non-magnetic transmitting coil can be adjusted to a preset coupling position through a position adjustment instruction.

[0037] Accordingly, if Figure 2 As shown, step S120 includes: S121, generating a position adjustment instruction; S122, adjusting the non-magnetic transmitting coil to a preset coupling position based on the position adjustment instruction, wherein, at the preset coupling position, the non-magnetic transmitting coil of the charger is coupled to the receiving coil of the device to be charged.

[0038] In step S121, a position adjustment instruction is generated. Specifically, when the "preset condition is not met" event occurs, the position adjustment instruction is automatically generated.

[0039] In step S120, the non-magnetic transmitting coil is adjusted to a preset coupling position based on the position adjustment instruction. Specifically, the real-time position of the non-magnetic transmitting coil is obtained; a motor drive signal is generated based on a comparison between the real-time position and the preset coupling position; and the motor drive signal is used to drive a motor to move the non-magnetic transmitting coil to the preset position.

[0040] In an embodiment of the present application, a plurality of preset coupling positions are provided, and the non-magnetic transmitting coil can be adjusted to each of the preset coupling positions in sequence based on the position adjustment instruction until the receiving coil of the device to be charged is successfully paired with the non-magnetic transmitting coil and charging begins.

[0041] Accordingly, if Figure 3 As shown, step S122 includes: S1221, adjusting the non-magnetic transmitting coil to a preset coupling position among a plurality of preset coupling positions based on the position adjustment instruction; S1222, in response to the non-magnetic transmitting coil being unable to start charging when the non-magnetic transmitting coil is adjusted to the preset coupling position, adjusting the non-magnetic transmitting coil to another preset coupling position based on another position adjustment instruction until the device to be charged starts charging.

[0042] like Figure 4 As shown, in one example of the present application, N preset coupling positions are provided, and the non-magnetic transmitting coil is adjusted to the first preset coupling position (i.e., position 1) based on the position adjustment instruction; if the device to be charged cannot start charging when the non-magnetic transmitting coil is adjusted to the first preset coupling position (i.e., position 1), another position adjustment instruction is automatically generated, and the non-magnetic transmitting coil is adjusted to the second preset coupling position (i.e., position 2) based on the other position adjustment instruction; if the device to be charged cannot start charging when the non-magnetic transmitting coil is adjusted to the second preset coupling position (i.e., position 2), another position adjustment instruction is automatically generated, and the non-magnetic transmitting coil is adjusted to the next preset coupling position based on the another position adjustment instruction until the device to be charged starts charging.

[0043] In one embodiment of the present application, when the non-magnetic transmitting coil is adjusted to the preset coupling position, the device to be charged starts charging, and the non-magnetic transmitting coil is maintained at the preset coupling position.

[0044] In another embodiment of the present application, when the non-magnetic transmitting coil is adjusted to the preset coupling position, the device to be charged starts charging, and the position of the non-magnetic transmitting coil is fine-tuned until the coupling degree between the non-magnetic transmitting coil and the receiving coil of the device to be charged is optimal. Figure 5 As shown, step S122 includes: S1221, adjusting the non-magnetic transmitting coil to a preset coupling position among a plurality of preset coupling positions based on the position adjustment instruction; S1223, in response to the charging device starting to charge when the non-magnetic transmitting coil is adjusted to the preset coupling position, moving around the preset coupling position based on another position adjustment instruction until the coupling degree between the non-magnetic transmitting coil and the receiving coil of the device to be charged is optimal.

[0045] In step S1223, the degree of coupling between the non-magnetic transmitting coil and the receiving coil of the device to be charged may be determined based on a power loss value of the receiving power of the receiving coil of the device to be charged relative to the transmitting power of the non-magnetic transmitting coil. The lower the power loss value of the receiving power of the receiving coil of the device to be charged relative to the transmitting power of the non-magnetic transmitting coil, the higher the degree of coupling between the non-magnetic transmitting coil and the receiving coil of the device to be charged.

[0046] It is worth mentioning that it should be understood that when the device to be charged (for example, a mobile phone) is switching the charging mode, the charging icon will light up twice, which may affect the user experience. The switching time from the magnetic charging mode to the non-magnetic charging mode in this application is relatively fast. For example, in one embodiment of the present application, the switching time from the magnetic charging mode to the non-magnetic charging mode is less than 1 second, which can avoid, to a certain extent, the charging icon of the device to be charged (for example, a mobile phone) lighting up twice during the switching from the magnetic charging mode to the non-magnetic charging mode. It should be understood that in other embodiments of the present application, the switching time from the magnetic charging mode to the non-magnetic charging mode may be other values, for example, less than 2 seconds, less than 3 seconds, etc.

[0047] Based on the mechanism of the wireless charging positioning method based on multiple charging modes, this application proposes a wireless charging positioning system based on multiple charging modes. Figure 6 The wireless charging positioning system based on multiple charging modes according to an embodiment of the present application is described.

[0048] Figure 6 The figure shows a block diagram of a wireless charging positioning system based on multiple charging modes according to an embodiment of the present application.

[0049] like Figure 6 As shown, the wireless charging positioning system based on multiple charging modes includes a processor 10, a memory 20, a magnetic transmitting coil 30, a non-magnetic transmitting coil 40, and a motor 50. The motor 40 is connected to the processor 10; the non-magnetic transmitting coil 40 is installed on the motor 50.

[0050] The processor 10 may be a central processing unit (CPU) or other processing units with data processing capabilities and / or instruction execution capabilities, and may control other components in the wireless charging positioning system based on multiple charging modes to perform desired functions.

[0051] The memory 20 may include one or more computer program products, which may include various forms of computer-readable storage media, such as volatile memory and / or non-volatile memory. The volatile memory may include, for example, random access memory (RAM) and / or cache memory. The non-volatile memory may include, for example, read-only memory (ROM), a hard disk, flash memory, etc. One or more computer program instructions may be stored on the computer-readable storage medium, and the processor 10 may execute the program instructions to implement the wireless charging positioning method based on multiple charging modes and / or other desired functions described in the various embodiments of the present application described above.

[0052] The processor 10 includes a magnetic charging control module 11 and a non-magnetic charging control module 12. The magnetic charging control module 11 is used to detect whether a preset condition is met within a preset time window through the magnetic transmitting coil of the charger; the non-magnetic charging control module 12 is used to switch the charging mode to the non-magnetic charging mode in response to not meeting the preset condition.

[0053] In one embodiment of the present application, the non-magnetic charging control module is further configured to generate a position adjustment instruction in response to failure to meet a preset condition; and adjust the non-magnetic transmitting coil to a preset coupling position based on the position adjustment instruction, wherein, at the preset coupling position, the non-magnetic transmitting coil of the charger is coupled to the receiving coil of the device to be charged.

[0054] In one embodiment of the present application, the non-magnetic charging control module is further configured to adjust the non-magnetic transmitting coil to one of a plurality of preset coupling positions based on the position adjustment instruction; in response to the device to be charged being unable to start charging when the non-magnetic transmitting coil is adjusted to the preset coupling position, the non-magnetic transmitting coil is adjusted to another preset coupling position based on another position adjustment instruction until the device to be charged starts charging.

[0055] In one embodiment of the present application, the non-magnetic charging control module is further configured to adjust the non-magnetic transmitting coil to one of a plurality of preset coupling positions based on the position adjustment instruction; in response to the non-magnetic transmitting coil being adjusted to the preset coupling position, the device to be charged starts charging, and the non-magnetic transmitting coil moves around the preset coupling position based on another position adjustment instruction until the degree of coupling between the non-magnetic transmitting coil and the receiving coil of the device to be charged is optimal.

[0056] In summary, the wireless charging positioning method and system based on multiple charging modes are described. The wireless charging positioning method based on multiple charging modes can realize multi-mode charging of a single charging device to improve the versatility of the charger.

[0057] The above description of the present application and its embodiments is non-limiting. The drawings show only one embodiment of the present application, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of this application, designs a structure and embodiment similar to this technical solution without creatively designing, they shall fall within the scope of protection of this application.
