[0002] Currently, more and more devices support wireless charging, but improper placement is a frequent problem during use. Most users don't know the exact location of the receiver (RX, receive) coil on the device being charged, nor the location of the transmitter (TX, transport) coil in the charging dock. Therefore, devices are often placed at an angle, affecting charging efficiency. Additionally, the transmitter coil increases its transmission power to compensate for transmission power, resulting in energy waste.
[0003] Therefore, there is an urgent need for a method to determine whether the receiving coil of the device to be charged is aligned with the transmitting coil of the charging base. Summary of the Invention

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0052] like Figure 1 The diagram illustrates an application scenario of an information processing method provided in this application. This scenario includes a device to be charged 101 and a charging device 102. The device to be charged is equipped with a third coil 103, and the charging device is equipped with a second coil 104. The device to be charged and the charging device are brought close enough to reach the distance required for charging. The second coil of the charging device emits energy, and the third coil of the device to be charged receives this energy to generate a charging voltage and a charging current, thereby charging the device to be charged. The third coil can be a receiving coil, and the second coil can be a transmitting coil.
[0053] like Figure 2 The diagram shown is a flowchart of an embodiment 1 of an information processing method provided in this application. The method is applied to a device to be charged and includes the following steps:
[0054] Step S201: Obtain the induction signal generated by the first coil installed in the device to be charged;
[0055] The induction signal is generated by the first coil sensing the energy sent by the second coil of the charging device. The device to be charged is also provided with a third coil, and the positions of the first coil and the third coil are relatively fixed.
[0056] The third coil in the device to be charged is used to receive energy sent by the second coil of the charging device to charge the device.
[0057] In this design, the first coil and the third coil in the device to be charged are positioned relatively fixed. The first coil can also sense the energy sent by the second coil of the charging device and generate an induction signal. The first coil can be an auxiliary coil.
[0058] The positions of the first coil and the third coil are relatively fixed, and the energy received by the first coil is related to the energy received by the third coil.
[0059] Generally, the number of first coils in the device to be charged is greater than or equal to 2.
[0060] Specifically, the plurality of first coils are arranged on the same plane, and the plurality of first coils do not overlap, and the center of the plurality of first coils overlaps with the center of the third coil. The side length of the pattern formed by the plurality of first coils is greater than the diameter of the third coil. In the vertical direction, the third coil passes through part or all of the plurality of first coils in sequence to ensure that the magnetic field lines passing through the third coil are within the area of the pattern formed by the plurality of first coils.
[0061] If there are two first coils, only a one-dimensional coordinate system can be established. When calculating the direction of movement, there is only one direction, and the movement distance is only the distance in this one direction.
[0062] Since three non-collinear first coils can define a plane, the magnetic field strength in at least two dimensions can be obtained, which can be used to establish a two-dimensional coordinate system for subsequent calculation of the direction and distance of movement.
[0063] It should be noted that these multiple first coils are symmetrically arranged to provide a convenient calculation basis for subsequently determining the direction and distance of movement.
[0064] like Figure 3 The diagram shows a device to be charged, which includes a third coil 301 and a first coil 302. The first coil is represented by a thin solid line, and the third coil by a dashed line. The left diagram uses three first coils as an example, and the right diagram uses four first coils as an example. The three first coils form a rounded triangle, and the four first coils form a rounded square. The center of the rounded triangle / square overlaps with the center of the third coil. The side length of the rounded triangle / square is greater than the diameter of the third coil. The third coil passes through the three / four first coils respectively to ensure that the magnetic field lines passing through the third coil are within the area of the rounded triangle / square.
[0065] The third coil is disposed on a receiving coil plate. The top view of the receiving coil plate is a rounded square. Multiple first coils can be disposed along the edge of the receiving coil plate, such that each first coil is tangent to the edge of the receiving coil plate and adjacent first coils are tangent. Alternatively, multiple first coils can be disposed along the edge of the receiving coil plate, with some first coils disposed inside the receiving coil plate and adjacent first coils being tangent.
[0066] In practice, to reduce the complexity of setting up the first coil, a first coil with a larger diameter is generally set, and only one loop of the first coil is set around the center position, which is the center position of the pattern composed of multiple first coils.
[0067] It should be noted that the induced signal generated by the first coil can be an induced voltage. When magnetic field lines pass through the first coil (energy reaches the first coil), the first coil induces a current. The device to be charged rectifies the induced current to obtain a rectified current, and then converts the rectified current into an induced voltage.
[0068] Step S202: Determine whether the relative position of the third coil and the second coil satisfies the target position condition based on the sensing signal.
[0069] The induced signals of the multiple first coils indicate the amount of energy received by the second coil at the location of the first coil.
[0070] If the multiple first coils receive the same amount of energy, and the shape of the second coil corresponds to the shape of the third coil, then it means that the pattern formed by the multiple first coils overlaps with the second coil, so the third coil is aligned with the second coil.
[0071] If the energy received by the multiple first coils is different, it means that the pattern formed by the multiple first coils does not overlap with the second coil. Therefore, the third coil is not aligned with the second coil.
[0072] In subsequent embodiments, the question of whether the relative position satisfies the target position condition will be explained in detail, but will not be elaborated on in this embodiment.
[0073] In summary, this embodiment provides an information processing method in which a device to be charged is provided with a third coil and a first coil. The method includes: obtaining an induction signal generated by the first coil in the device to be charged, wherein the induction signal is generated by the first coil sensing energy transmitted by a second coil of the charging device; the device to be charged is also provided with a third coil, and the positions of the first coil and the third coil are relatively fixed; and determining whether the relative position of the third coil and the second coil satisfies a target position condition based on the induction signal. In this solution, by detecting the induction signal of the first coil, the device to be charged can determine whether the relative position of its third coil and the second coil of the charging device satisfies the target position condition, that is, whether the third coil is aligned with the second coil of the charging device.
[0074] like Figure 4 The diagram shown is a flowchart of an embodiment 2 of an information processing method provided in this application. The method includes the following steps:
[0075] Step S401: Obtain the induction signal generated by the first coil installed in the device to be charged;
[0076] Step S401 is the same as step S201 in Embodiment 1, and will not be described again in this embodiment.
[0077] Step S402: If the induction signals of at least two of the first coils do not meet the preset signal conditions, determine that the relative position of the third coil and the second coil does not meet the target position conditions.
[0078] The device to be charged stores preset signal conditions. It judges whether the induction signals of multiple first coils meet the preset signal conditions. If the preset signal conditions are met, the relative position of the third coil and the second coil meets the target position condition. If the preset signal conditions are not met, the relative position of the third coil and the second coil does not meet the target position condition.
[0079] The device to be charged is provided with at least two first coils. Each first coil obtains an induction signal based on the number of magnetic field lines passing through it. The larger the induction signal, the more magnetic field lines pass through it; otherwise, the fewer magnetic field lines pass through it.
[0080] The preset signal condition can be whether the induction signals of multiple first coils are consistent. In specific implementation, it can be whether the difference between the induction signals is less than a threshold.
[0081] Specifically, if the difference between the induction signals of any two first coils is greater than a threshold, it can be determined that the induction signals of the two coils are inconsistent. If the induction signals of multiple first coils do not meet the preset signal conditions, it can be determined that the relative position of the third coil and the second coil does not meet the target position conditions.
[0082] In summary, the information processing method provided in this embodiment includes: determining that the relative position of the third coil and the second coil does not meet the target position condition when the induction signals of at least two of the first coils do not meet the preset signal condition. In this solution, it is only necessary to judge based on the induction signals of multiple first coils to determine whether the relative position of the third coil and the second coil meets the target position condition, thus achieving accurate determination of whether the relative position meets the target position condition.
[0083] like Figure 5 The diagram shown is a flowchart of an embodiment 3 of an information processing method provided in this application. The method includes the following steps:
[0084] Step S501: Obtain the induction signal generated by the first coil installed in the device to be charged;
[0085] Step S502: Determine whether the relative position of the third coil and the second coil satisfies the target position condition based on the sensing signal;
[0086] Steps S501-502 are the same as steps S201-202 in Example 1, and will not be described again in this example.
[0087] Step S503: If the relative position between the third coil and the second coil determined based on the sensing signal does not meet the target position condition, determine the moving direction and / or moving distance of the third coil according to the sensing signal, so that after the third coil moves based on the moving direction and / or moving distance, the relative position meets the target position condition.
[0088] If it is determined that the relative position of the third coil and the second coil does not meet the target position condition, in order to improve the charging efficiency, it is necessary to adjust the position of the third coil of the device to be charged so that the third coil moves to a position where the relative position meets the target position condition.
[0089] Specifically, the direction and / or distance of movement of the third coil are determined based on the induction signal.
[0090] Since the induced signal is generated based on the amount of energy received by the first coil, and the amount of energy received corresponds to the overlapping area of the second coil, the first coil with a larger induced signal has a larger overlapping area with the second coil compared to the first coil with a smaller induced signal, and it is closer to the center of the second coil.
[0091] like Figure 6 The diagram shows a schematic of the first and second coils. The first coil is represented by a thin solid line, while the second coil is represented by a dotted line. The first coil is a rounded square, the center of which is not aligned with the center of the second coil. First coil 1 is closest to the center of the second coil, with the largest overlap area. First coil 4 is farthest from the center of the second coil, with the smallest overlap area. The induced signal of first coil 1 is the largest, the induced signal of first coil 4 is the smallest, and the induced signals of first coils 2 and 3 are in the middle range.
[0092] Specifically, based on the induced signals of the multiple first coils, it is determined to move in the direction of the first coil with a larger induced signal, so that the first coil with a larger induced signal is slightly away from the center of the second coil, thereby reducing its induced signal, and the first coil with a smaller induced signal is slightly closer to the center of the second coil, thereby increasing its induced signal.
[0093] The distance moved can also be determined based on the induction signals of the multiple first coils. The following description will explain in detail how to determine the distance moved, which will not be detailed in this embodiment.
[0094] In summary, the information processing method provided in this embodiment further includes: if the relative position between the third coil and the second coil, determined based on the sensing signal, does not meet the target position condition, determining the moving direction and / or moving distance of the third coil according to the sensing signal, so that after the third coil moves based on the moving direction and / or moving distance, the relative position meets the target position condition. In this solution, the moving direction and / or moving distance of the third coil can be determined based on the sensing signals of multiple first coils, so that the third coil is moved based on the moving direction and moving distance to a position where its relative position with the second coil meets the target position condition, ensuring that the third coil is ultimately aligned with the second coil and improving charging efficiency.
[0095] like Figure 7 The diagram shown is a flowchart of an embodiment 4 of an information processing method provided in this application. The method includes the following steps:
[0096] Step S701: Obtain the induction signal generated by the first coil installed in the device to be charged;
[0097] Step S702: Determine whether the relative position of the third coil and the second coil satisfies the target position condition based on the sensing signal;
[0098] Steps S701-702 are the same as steps S201-202 in Example 1, and will not be described again in this example.
[0099] Step S703: If the relative position between the third coil and the second coil determined based on the sensing signal does not meet the target position condition, the moving direction and / or moving distance of the third coil is determined based on the difference between the sensing signals of the plurality of first coils.
[0100] Since the induced signal is generated based on the amount of energy received by the first coil, and the amount of energy received corresponds to the overlapping area of the second coil, the amount of overlapping area between the induced signal of the first coil and the second coil can be determined based on the amount of energy received by the first coil.
[0101] If the induced signals of any two first coils are the same, it indicates that their overlapping areas with the second coil are the same. If there is a difference in the induced signals of any two first coils, it indicates that their overlapping areas with the second coil are not the same.
[0102] Specifically, the difference in the induced signals between multiple first coils represents the difference in the overlapping area between the multiple first coils and the second coil. Since the first coils are symmetrically arranged, the difference in the overlapping area between the multiple first coils and the second coil indicates the positional offset between the third coil and the second coil in the charging device itself.
[0103] Specifically, based on the difference in the induced signals between the first coils, the offset direction and offset distance between the center of the third coil and the center of the second coil are determined. Correspondingly, the direction opposite to the offset direction is taken as the moving direction of the third coil, and the offset distance between the center of the third coil and the center of the second coil is taken as the moving distance of the third coil.
[0104] Specifically, in order to move the third coil in a two-dimensional direction, the number of the first coils must be at least three.
[0105] Specifically, step S703 includes:
[0106] Step S7031: Based on the difference between the induced signals of at least three of the first coils, determine the first offset distance of the third coil along the first direction and the second offset distance along the second direction;
[0107] The difference in the induced signal between any two first coils represents the gap between the overlapping areas of the two first coils and the second coil. The larger the difference, the greater the gap between the overlapping areas of the two first coils and the second coil, and the greater the offset between the center of the third coil and the center of the second coil.
[0108] Specifically, two reference directions (the first direction and the second direction) are determined, and these two reference directions are used as the basis for calculating the offset distance of the third coil.
[0109] In practice, these two reference directions can be used as the XY axes to establish a planar coordinate system, and the distances that the third coil is offset from the second coil along the two reference directions can be determined.
[0110] Step S7032: Determine the direction of movement and the distance of movement in the direction of movement based on the first offset distance and the second offset distance.
[0111] The offset direction of the third coil relative to the second coil can be determined based on the first offset distance of the third coil relative to the second coil in the first direction and the second offset distance in the second direction.
[0112] The direction opposite to the offset direction is determined as the moving direction, and the corresponding distance is determined as the moving distance based on the first offset distance and the second offset distance.
[0113] like Figure 8 The diagram shown illustrates the determination of the direction and distance of movement. This diagram uses four first coils as an example. These include the third coil 801 and the first coil 802 as shown in the left diagram. Taking the induced signal as the induced voltage, the induced voltages of the four first coils are V1, V2, V3, and V4, respectively. The voltage differences between two adjacent first coils are calculated sequentially to obtain V12, V13, V24, and V34.
[0114] Among them, V12=V1–V2, V13=V1–V3, V24=V2–V4, V34=V3-V4.
[0115] In this arrangement, first coil 1 and first coil 2, first coil 3 and first coil 4 are arranged along the horizontal direction (X-axis), and V12 and V34 are the voltage differences along the X-axis; first coil 1 and first coil 3, first coil 2 and first coil 4 are arranged along the vertical direction (Y-axis), and V13 and V24 are the voltage differences along the Y-axis. To prevent excessive movement of the third coil in the future, the smaller voltage difference is selected as the offset distance, that is, MIN(V13, V24) is selected as the offset distance in the Y-axis direction, and MIN(V12, V34) is selected as the offset distance in the X-axis direction.
[0116] like Figure 8As shown in the middle right figure, in a two-dimensional rectangular coordinate system, the offset distance between the X-axis and the Y-axis is determined. The offset direction can be represented by the included angle α. Specifically, the value of the included angle α is obtained by calculating based on the offset distances between the X-axis and the Y-axis MIN(V12, V34) and MIN(V13, V24).
[0117] In summary, the information processing method provided in this embodiment includes: determining the moving direction and / or moving distance of the third coil based on the difference in the induced signals between multiple first coils. In this solution, the induced signal of the first coil is related to its overlapping area with the second coil. Since the positions of the first coil and the third coil in the charging device are fixed, the difference in the overlapping area between each first coil and the second coil can be determined based on the difference in the induced signals. Based on this difference in the induced signals, the offset position and offset direction of the third coil relative to the second coil can be determined, and the moving direction and / or moving distance of the third coil can be determined accordingly. This allows the third coil to be moved to a position where its relative position to the second coil satisfies the target position condition, ensuring that the third coil is ultimately aligned with the second coil and improving charging efficiency.
[0118] like Figure 9 The flowchart shown is a 5th embodiment of an information processing method provided in this application. The method includes the following steps:
[0119] Step S901: Obtain the induction signal generated by the first coil installed in the device to be charged;
[0120] Step S902: Determine whether the relative position of the third coil and the second coil satisfies the target position condition based on the sensing signal;
[0121] Step S903: If the relative position between the third coil and the second coil determined based on the sensing signal does not meet the target position condition, determine the moving direction and / or moving distance of the third coil according to the sensing signal;
[0122] Steps S901-903 are the same as steps S501-503 in Example 3, and will not be described again in this example.
[0123] Step S904: Generate prompt information based on the moving direction and / or moving distance. The prompt information is used to prompt the operator to move the device to be charged to the target position to meet the target position conditions.
[0124] The device to be charged has a prompting function structure, which may include at least one of the following: an audio output module and a display screen, etc.
[0125] After determining the direction and / or distance of movement of the third coil, a prompt message is generated to prompt the operator to move the device to be charged to the target location.
[0126] It should be noted that after moving the device to be charged once, it is checked again whether the relative position of the third coil and the second coil meets the target position conditions. If not, the operator is prompted to move the device to be charged again.
[0127] Specifically, the prompt message is displayed as an image on the screen, such as a prompt arrow. The direction of the arrow indicates the direction of movement, and the length / thickness of the arrow is positively correlated with the distance moved.
[0128] like Figure 10 The diagram shows a prompt indicating the direction of movement. The arrow points to the upper left, prompting the operator to move the device to be charged to the upper left.
[0129] Specifically, the audio output module outputs prompts, such as the audio message "Move to the left," to prompt the operator to move the device to be charged.
[0130] In summary, the information processing method provided in this embodiment further includes: generating prompt information based on the movement direction and / or movement distance, the prompt information being used to prompt the operator to move the device to be charged to a target position to meet the target position condition. In this solution, prompt information is generated based on a determined movement direction and / or movement distance to prompt the operator to move the device to be charged to the target position, ultimately ensuring that the relative position of the third coil and the second coil meets the target position condition, ensuring that the third coil and the second coil are ultimately aligned, and improving charging efficiency.
[0131] like Figure 11 The flowchart shown is a sample of embodiment 6 of an information processing method provided in this application. The method includes the following steps:
[0132] Step S1101: Obtain the induction signal generated by the first coil installed in the device to be charged;
[0133] Step S1102: Determine whether the relative position of the third coil and the second coil satisfies the target position condition based on the sensing signal;
[0134] Step S1103: If the relative position between the third coil and the second coil determined based on the sensing signal does not meet the target position condition, determine the moving direction and / or moving distance of the third coil according to the sensing signal;
[0135] Steps S1101-1103 are the same as steps S501-503 in Example 3, and will not be described again in this example.
[0136] Step S1104: Generate a first control command based on the moving direction and / or moving distance. The first control command is used to instruct the drive module of the device to be charged to drive the third coil to move to the target position to meet the target position conditions.
[0137] The device to be charged includes a drive module, which is used to drive the third coil to move.
[0138] The drive module controls the third coil to move to the target position based on the first control command.
[0139] The drive module moves the third coil to the target position along the moving direction / based on the moving distance.
[0140] It should be noted that, in actual implementation, the drive module moves the third coil and the first coil synchronously.
[0141] In practice, to reduce the complexity of the driving module, it is only necessary to drive it in two directions, such as moving it in two perpendicular directions on the plane where the third coil is located.
[0142] In practice, the third coil and the 4-rail position adjustment system are installed inside the device to be charged. Based on the rails in the horizontal and vertical directions, the position of the third coil can be adjusted in both directions.
[0143] Specifically, step S1104 includes:
[0144] Step S11041: Based on the preset movement step length rule and the first offset distance, determine the first step length, wherein the first step length is the step length of movement along the first direction;
[0145] Step S11042: Based on the preset movement step length rule and the second offset distance, determine the second step length, which is the step length of movement along the second direction;
[0146] Step S11043: Determine the first moving direction and the second moving direction based on the offset direction;
[0147] Step S11044: Generate a first control command based on the first moving direction and the first step length, the second moving direction and the second step length. The first control command is used to control the third coil to move the first step length in the first moving direction and the second step length in the second moving direction in sequence.
[0148] Specifically, the step size rule is to take the square root of the offset distance as the step size.
[0149] It should be noted that, in specific implementation, after each movement of the third coil based on a determined step size, it can be determined again whether the relative position of the third coil and the second coil meets the target position condition. If not, the first control command is generated again to control the movement of the third coil.
[0150] like Figure 12 The diagram shown illustrates the adjustment of the third coil. This diagram uses four first coils as an example. The first coils are represented by thin solid lines, while the third coil is represented by dashed lines. The top image shows the position of the third coil before adjustment, and the bottom image shows its position after adjustment.
[0151] In summary, the information processing method provided in this embodiment further includes: generating a first control command based on the movement direction and / or movement distance, wherein the first control command is used to instruct the drive module of the device to be charged to drive the third coil to move to the target position to satisfy the target position condition. In this solution, the first control command is generated based on the determined movement direction and / or movement distance to instruct the drive module of the device to be charged to drive the third coil to move to the target position, automatically adjusting the relative position of the third coil and the second coil to satisfy the target position condition, ensuring that the third coil and the second coil are finally aligned, and improving charging efficiency.
[0152] like Figure 13 The diagram shown is a flowchart of an embodiment 7 of an information processing method provided in this application. The method is applied to a charging device and includes the following steps:
[0153] Step S1301: Obtain the induction signal generated by the first coil installed in the device to be charged;
[0154] The induction signal is generated by the first coil sensing the energy sent by the second coil of the charging device. The device to be charged is also provided with a third coil, and the positions of the first coil and the third coil are relatively fixed.
[0155] In this system, the second coil of the charging device sends energy, the third coil of the device to be charged charges based on the received energy, and the first coil of the device to be charged receives the energy and generates an induction signal.
[0156] In this process, the charging device obtains the induced signal from the device to be charged.
[0157] In practice, data can be transmitted through a wireless information transmission channel between the charging device and the device to be charged. The device to be charged only needs to send the voltage value of the sensed signal to the charging device.
[0158] Step S1302: Determine whether the relative position of the third coil and the second coil satisfies the target position condition based on the sensing signal;
[0159] The induced signals of the multiple first coils indicate the amount of energy received by the second coil at the location of the first coil.
[0160] If the multiple first coils receive the same amount of energy, and the shape of the second coil corresponds to the shape of the third coil, then it means that the pattern formed by the multiple first coils overlaps with the second coil, so the third coil is aligned with the second coil.
[0161] If the energy received by the multiple first coils is different, it means that the pattern formed by the multiple first coils does not overlap with the second coil. Therefore, the third coil is not aligned with the second coil.
[0162] Specifically, to determine whether the relative position of the third coil and the second coil meets the target position condition, please refer to the aforementioned method embodiment 2, which will not be described in detail in this embodiment.
[0163] Step S1303: If not, generate a second control command based on the sensing signal. The second control command is used to adjust the magnetic attraction strength of the charging device to adjust the position of the device to be charged.
[0164] If the relative position of the third coil and the second coil does not meet the target position condition, the offset position and / or offset direction of the third coil and the second coil can be determined based on the sensing signal. Correspondingly, the moving direction and / or moving distance of the third coil can be determined so that after the third coil moves based on the moving direction and / or moving distance, the relative position meets the target position condition.
[0165] Specifically, the charging device and the device to be charged are attracted by magnetic force to achieve non-contact and fixed relative position. Correspondingly, by controlling the different magnetic attraction in different areas of the charging device, the magnetic attraction between the charging device and the device to be charged is different in different areas, so that the device to be charged moves to the target position under the guidance of the difference in magnetic attraction.
[0166] like Figure 14The diagram shows a magnetic attraction schematic of a charging device. This device has four magnetic attraction areas 1401-1404 and a second coil 1405. In the left diagram, the magnetic attraction strength of the four areas is the same. If the relative position of the device to be charged and the charging device does not meet the target position conditions, and it is determined that the device to be charged needs to be moved to the upper left (as shown by the arrow), then the magnetic attraction strength of magnetic attraction area 1401 is increased, the strength of magnetic attraction areas 1402 and 1403 is decreased, and the magnetic attraction strength of magnetic attraction area 1404 is reduced to the minimum. A square wave is used to represent the magnetic attraction strength in the diagram.
[0167] In summary, this embodiment provides an information processing method applied to a charging device. The method includes: obtaining an induction signal generated by a first coil in the device to be charged, wherein the induction signal is generated by the first coil sensing energy emitted by a second coil of the charging device, and the device to be charged also has a third coil, with the positions of the first coil and the third coil relatively fixed; determining whether the relative position of the third coil and the second coil meets a target position condition based on the induction signal; if not, generating a second control command based on the induction signal, the second control command being used to adjust the magnetic attraction strength of the charging device to adjust the position of the device to be charged. In this solution, the charging device, based on the induction signal from the first coil in the device to be charged, can determine whether the relative position of its second coil and the device to be charged meets the target position condition. If not, the position of the device to be charged is adjusted to the target position by adjusting the magnetic attraction strength of the charging device, thereby ensuring that the third coil and the second coil are ultimately aligned and improving charging efficiency.
[0168] like Figure 15 The diagram shown is a flowchart of an embodiment 8 of an information processing method provided in this application. The method includes the following steps:
[0169] Step S1501: Obtain the induction signal generated by the first coil installed in the charging device;
[0170] The induction signal is generated by the first coil sensing the energy sent by the third coil of the device to be charged. The charging device is also provided with a second coil, and the positions of the first coil and the second coil are relatively fixed.
[0171] The first coil, which can be an auxiliary coil, is installed in the charging device. The first coil is used to sense the energy transmitted by the third coil of the device being charged to generate an induction signal. The charging device also includes a second coil, which is typically a TX coil.
[0172] It should be noted that the process in this embodiment is divided into two stages: the first stage is the position alignment stage, and the second stage is the charging stage. During the position alignment stage, the third coil in the device to be charged is in a first operating mode, acting as a transmitting coil to emit energy. The emitted energy is sensed by the first coil in the charging device to generate an induction signal. Steps S1501-S1503 belong to the process steps of the position alignment stage.
[0173] After the alignment stage, when in the charging stage, the third coil in the device to be charged is in the second working mode, and the third coil acts as a receiving coil. At this time, the second coil in the charging device acts as a transmitting coil, and the second coil emits energy. The emitted energy is induced by the third coil, thereby charging the device to be charged.
[0174] Step S1502: Determine whether the relative position of the second coil and the third coil satisfies the target position condition based on the sensing signal;
[0175] Specifically, to determine whether the relative positions of the second coil and the third coil meet the target position conditions, please refer to the aforementioned method embodiments, which will not be detailed in this embodiment.
[0176] Step S1503: If not, generate a second control command based on the sensing signal. The second control command is used to instruct the second coil to move to the target position to meet the target position conditions.
[0177] Specifically, the charging device may include a drive module, which is used to drive the second coil to move.
[0178] The drive module controls the second coil to move to the target position based on the second control command.
[0179] The drive module moves the second coil to the target position along the moving direction / based on the moving distance, and the method for determining the moving direction or moving distance is as described in the aforementioned embodiment.
[0180] It should be noted that, in practice, the drive module moves the second coil and the first coil synchronously.
[0181] In practice, to reduce the complexity of the driving module, it is only necessary to drive it in two directions, such as moving it in two perpendicular directions on the plane where the second coil is located.
[0182] In practice, the second coil and the 4-rail position adjustment system are installed inside the charging equipment. Based on the rails in both the horizontal and vertical directions, the position of the second coil can be adjusted in both directions.
[0183] The method for calculating the movement step size of the drive module is as shown in the aforementioned embodiment 6.
[0184] In summary, the information processing method provided in this embodiment, during the alignment stage, uses a first coil installed in the charging device to sense the energy emitted by a third coil in the device to be charged. Based on the sensing signal generated by the first coil, it determines whether the relative positions of the second and third coils meet the target position conditions. If the target position conditions are not met, the driving module of the charging device can automatically adjust the second coil to move to the target position to satisfy them. This embodiment, by installing the first coil on the charging device side instead of the device to be charged side, reduces the number of components in the device to be charged, without increasing the internal structural complexity. Furthermore, when the second and third coils do not meet the target position conditions, the charging device adjusts the position of the second coil to automatically align it with the third coil, improving the automation level of the alignment process.
