detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

A method for prompting alignment of a wireless charging base and a mobile terminal provided by the present invention will be described in detail below by enumerating several specific embodiments.

Embodiment one

A method for prompting the alignment of a wireless charging base provided by an embodiment of the present invention is introduced in detail.

Referring to FIG. 1 , it shows a flowchart of steps of a method for prompting the alignment of a wireless charging base in an embodiment of the present invention.

Step 110, when the mobile terminal is placed on the wireless charging base, the induced electromotive force of the at least one pair of orthogonally arranged alignment auxiliary coils is obtained.

FIG. 1A is a structural diagram of an existing wireless charging system. Existing wireless charging systems mainly include a transmitter (Base Station) and a receiver (Mobile Device).

The transmitter mainly includes 4 units: Power Supply, Power Conversion Unit, Communications&Control Unit, and Primary Cell. Among them, the power supply unit is responsible for providing power for wireless transmission; the power conversion unit is responsible for power conversion (usually low-frequency DC to high-frequency AC); the communication control unit is responsible for establishing communication with the receiving end (Mobile Device), receiving device information from the receiving end and Power demand information. The role of the transmitting coil in the conversion unit is to generate a time-varying current in the coil, and the time-varying current in the transmitting coil makes a time-varying magnetic field around the coil, thereby completing the conversion process of electromagnetism.

The receiving end mainly includes 4 units: receiving coil (Secondary Cell), power pickup unit (PowerPick-up Unit), communication control unit, and load unit (Load). The receiving coil is the charging coil, and the receiving coil is placed near the transmitting coil. In the time-varying magnetic field, an induced electromotive force will be generated on the receiving coil; the power pick-up unit is responsible for converting the induced electromotive force generated in the coil into DC power; communication The load of the control unit sends the equipment information and power demand information of the receiving end to the transmitting end. The load unit is other parts of the mobile terminal except the receiving module, such as a battery, and the load stores the energy of the receiving end.

Moreover, in practical applications, in order to facilitate the wireless charging of the mobile terminal, the receiving end can be set as a part of the wireless charging base, then when the mobile terminal is placed on the wireless charging base, it can establish a connection with the transmitting end and perform wireless charging. Of course, the aforementioned receiving end can also be integrated inside the mobile terminal, and so on. This embodiment of the present application does not limit it. In the embodiment of the present application, in order to determine the offset between the mobile terminal to be charged and the preset optimal charging position, at least a pair of orthogonally arranged alignment auxiliary coils may be provided in the charging coil at the receiving end. Moreover, in order to conveniently determine the preset optimal charging position, it can also be set that the current directions in the two alignment auxiliary coils arranged orthogonally are opposite. Then you can use the orthogonal alignment auxiliary coils in the alternating magnetic field, when the magnetic induction intensities in the respective alignment auxiliary coils are different or the magnetic inductions in the paired alignment auxiliary coils cancel each other out at different positions, and then determine the relative position of the mobile terminal. The offset from the preset optimal charging position.

Taking a pair of orthogonally placed alignment auxiliary coils in the charging coil as an example, FIG. 1B is a schematic diagram of a pair of orthogonally arranged alignment auxiliary coils at the receiving end. The dotted line is the receiving coil RX, and D1 and D2 are two alignment auxiliary coils placed orthogonally. The receiving circuit module can convert the AC power received by the receiving circuit module into DC power and detect the induction of the alignment auxiliary coils D1 and D2. Electromotive force, in the embodiment of the present application, the receiving circuit module may include the aforementioned power pick-up unit, communication control unit, load unit, etc., which is not limited in the embodiment of the present application. Wherein, the receiving coil and the alignment auxiliary coils D1 and D2 are designed at the receiving end at the same time, and the positional relationship of the three coils can be shown in FIG. 1B . It should be noted that, in the embodiment of this application, in order to facilitate the introduction of the principle, D1 and D2 are orthogonal to each other by 90 degrees, but the angular relationship between the two overlapping alignment auxiliary coils D1 and D2 can also be adjusted. This embodiment of the application is not limited. Moreover, the number of turns of each alignment auxiliary coil can also be set according to requirements before this step, or before any step before this step. For example, in FIG. There may be a part of D1 and D2 coils, which is not limited in this embodiment of the present application.

The direction of the arrow in the alignment auxiliary coil in FIG. 1B represents the current flow direction in the corresponding alignment auxiliary coil. It can be seen that the current flow direction of D1 in FIG. 1B is counterclockwise, and the current flow direction of D2 is clockwise, so that in The orthogonal centers of D1 and D2 can produce magnetic inductions that cancel each other out. When the receiving end is connected to the transmitting end, that is, when the mobile terminal is placed on the wireless charging base, if the center of the transmitting coil and the receiving coil are facing each other, according to the right-hand spiral law, in the orthogonal center in Figure 1B, the coil D1 The value of the magnetic induction between D2 and D2 is the largest, and the induced electromotive force of the D1 coil is approximately equal to the induced electromotive force of the D2 coil. However, if the center of the transmitting coil and the receiving coil deviates, the induced electromotive force of D1 and D2 will be different.

Therefore, in the embodiment of the present application, the offset parameter between the mobile terminal and the preset optimal charging position can be determined based on the induced electromotive force of the alignment auxiliary coil. Then firstly, it is necessary to acquire the induced electromotive force of the alignment auxiliary coil in the mobile terminal. Then firstly, when the mobile terminal is placed on the wireless charging base, it is necessary to obtain the induced electromotive force of at least a pair of orthogonally arranged alignment auxiliary coils arranged in the charging coil.

As mentioned above, the receiving circuit module can be used to detect the induced electromotive force of the alignment auxiliary coils D1 and D2, then the induced electromotive force of the alignment auxiliary coil can be obtained from the receiving circuit module. Certainly, in the embodiment of the present application, any available method or device may also be used to acquire the induced electromotive force of the alignment auxiliary coil, which is not limited in the embodiment of the present application.

Step 120, according to the induced electromotive force, determine an offset parameter between the mobile terminal and the preset optimal charging position of the wireless charging base.

As mentioned above, if the mobile terminal has been placed in the preset optimal charging position, the magnetic induction intensity between each pair of orthogonal alignment auxiliary coils in the charging coil will cancel each other to the maximum value, and when the mobile terminal and the preset optimal charging position If there is a deviation between the charging positions, the mutual cancellation value of the magnetic induction intensity between each pair of orthogonally placed alignment auxiliary coils in the charging coil will also change. Therefore, in the embodiment of the present application, the offset parameter between the mobile terminal and the preset optimal charging position can be determined according to the induced electromotive force of the alignment auxiliary coil.

In this embodiment of the application, the induced electromotive force of each alignment auxiliary coil can be directly used to represent the offset parameter between the mobile terminal and the preset optimal charging position; of course, it can also be calculated according to the correspondence between the induced electromotive force and the distance The offset of the mobile terminal relative to the preset optimal charging position is taken as an offset parameter; and so on. This embodiment of the present application does not limit it.

Step 130, displaying the offset parameters to prompt the user to adjust the mobile terminal to the preset optimal charging position according to the offset parameters.

In the embodiment of the present application, in order to prompt the user to move the mobile terminal to a preset optimal charging position during charging, the offset parameter may be displayed, for example, the offset parameter may be displayed on the display interface of the mobile terminal. Moreover, in order to facilitate mobile terminal users to know how to adjust the mobile terminal to move it to the preset optimal charging position, when displaying the offset parameter, the offset parameter can also be used to display the current and preset optimal charging position of the mobile terminal at the same time. Thus, the user can be prompted to adjust the mobile terminal to the preset optimal charging position according to the offset parameter.

For example, when displaying the offset parameters, a plane four-quadrant simulation coordinate diagram may be constructed with the preset optimal charging position as the origin, and coordinate points corresponding to the offset parameters may be displayed in the plane four-quadrant simulation coordinate diagram. Then, the distance relationship between the coordinate point corresponding to the offset parameter and the coordinate origin can be used to represent the offset degree of the mobile terminal relative to the preset optimal charging position, and the distance between the coordinate point corresponding to the offset parameter and the coordinate origin The larger the distance, the greater the offset of the mobile terminal relative to the preset optimal charging position. Then, according to the position of the coordinate point corresponding to the offset parameter relative to the origin, the user is prompted to adjust the mobile terminal to Preset the best charging position.

Of course, in this embodiment of the present application, any other available method can also be used to display the offset parameters on the display interface of the mobile terminal, so as to prompt the user to adjust the mobile terminal to the preset optimal charging position according to the offset parameters. The requirement is preset, which is not limited in this embodiment of the present application.

In the embodiment of the present invention, when the mobile terminal is placed on the wireless charging base, the induced electromotive force of the at least one pair of orthogonally arranged alignment auxiliary coils is obtained; according to the induced electromotive force, the mobile terminal and the The offset parameter of the preset optimal charging position of the wireless charging base; displaying the offset parameter to prompt the user to adjust the mobile terminal to the preset optimal charging position according to the offset parameter. Therefore, the user can be prompted in real time to adjust the mobile terminal to a preset optimal charging position according to the position of the mobile terminal, thereby improving the freedom experience of the mobile terminal during the charging process.

Embodiment two

A method for prompting the alignment of a wireless charging base provided by an embodiment of the present invention is introduced in detail.

Referring to FIG. 1 , it shows a flowchart of steps of a method for prompting the alignment of a wireless charging base in an embodiment of the present invention.

Step 210, when the mobile terminal is placed on the wireless charging base, the induced electromotive force of the at least one pair of orthogonally arranged alignment auxiliary coils is acquired.

Step 220, when the at least one pair of orthogonally arranged alignment auxiliary coils is a pair, characterize the movement by the induced electromotive force of two alignment auxiliary coils in the pair of orthogonally arranged alignment auxiliary coils An offset parameter between the terminal and the preset optimal charging position.

When the charging coil includes a pair of orthogonally placed alignment auxiliary coils, such as the alignment auxiliary coils D1 and D2 in FIG. 1B . The induced electromotive force obtained at this time includes the induced electromotive force of the two alignment auxiliary coils, so the induced electromotive force of each alignment auxiliary coil can be directly used to represent the offset parameter between the mobile terminal and the preset optimal charging position. For example, for the aforementioned alignment auxiliary coils D1 and D2, assuming that the induced electromotive force of D1 is E1, and the induced electromotive force of D2 is E2, then (E1, E2) can be directly used to represent the deviation between the mobile terminal and the preset optimal charging position. Of course, as mentioned above, the induced electromotive force can be converted into a distance, and then the offset parameter between the mobile terminal and the preset optimal charging position can be characterized, and so on. But it is obvious that the representation without conversion has the same effect and is relatively more efficient.

Step 230, generating a plane four-quadrant simulation coordinate diagram with the preset optimal charging position as the origin, and displaying coordinate points corresponding to the offset parameters in the plane four-quadrant simulation coordinate diagram.

In the embodiment of the present application, in order to display the offset position of the mobile terminal relative to the preset optimal charging position, it is necessary to generate a plane four-quadrant simulation coordinate map with the preset optimal charging position as the origin. In practical application, if the receiving coil of the mobile terminal corresponds to the position of the transmitting coil, it means that the charging effect of the mobile terminal is the best at this time, and the mobile terminal is at the preset optimal charging position at this time. Therefore, in the embodiment of the present application, the preset optimal charging position can be confirmed according to the historical charging record, and of course the preset optimal charging position can also be determined in any other available manner, which is not limited in the embodiment of the present application. In addition, in practical applications, the mobile terminal can deviate in any direction relative to the preset optimal charging position, and the induced electromotive force mentioned in the embodiment of the application has no direction, then if the charging coil is provided with a pair of orthogonally placed When aligning the auxiliary coil, corresponding to the same value of the induced electromotive force at this time, the mobile terminal can have four possible position points relative to the preset optimal charging position, that is, if the charging coil contains a pair of orthogonal When the alignment auxiliary coil is set, four coordinate points corresponding to the offset parameters can be displayed in the plane four-quadrant simulation coordinate diagram.

As can be seen from the aforementioned analysis, when the mobile terminal is located at the preset optimal charging position, the induced electromotive force of D1 and D2 is the smallest, then after generating a plane four-quadrant simulation coordinate map with the preset optimal charging position as the origin, the four-quadrant plane can be The coordinate origin of the simulation coordinate diagram is the value of the induced electromotive force of D1 and D2 when the mobile terminal is located at the preset optimal charging position, and then D1 and D2 can be marked in the four-quadrant plane simulation coordinate diagram according to the preset coordinate scale The real-time induced electromotive force, then the offset of the real-time induced electromotive force of D1 and D2 relative to the origin in the four-quadrant simulation coordinate diagram of the representative plane can represent the offset parameter between the mobile terminal and the preset optimal charging position. Wherein, the coordinate scale can be set before this step or any step before this step according to requirements, which is not limited in this embodiment of the present application.

For example, for the aforementioned alignment auxiliary coils D1 and D2 in FIG. 1B , the generated planar four-quadrant simulation coordinate diagram with the preset optimal charging position as the origin can be shown in FIG. 2A . The coordinate origin O corresponds to the preset optimal charging position, the d1 axis represents the induced electromotive force in the direction perpendicular/parallel to the length of the mobile terminal, and the d2 axis represents the induced electromotive force perpendicular to the direction d1. Wherein, the point O may also represent the orthogonal center where the magnetic inductions of D1 and D2 cancel each other out, which is not limited in this embodiment of the present application. It should be noted that the coordinates shown in Figure 2A cannot be understood as coordinates in mathematical operations. This coordinate can be regarded as the center when the transmitting and receiving are aligned, that is, the preset optimal charging position is the center, and the receiving The offset between the center of the coil and the center of the transmitting end is specifically expressed by the magnitude of the induced electromotive force in the alignment auxiliary coil to represent the distance. Among them, the relationship between the magnitude of the induced electromotive force and the distance is that the greater the distance, the greater the induced electromotive force; the smaller the distance, the smaller the induced electromotive force. Then, when the receiving end of the mobile terminal is randomly placed on the transmitting end for the first time, an induced electromotive force E1 and E2 are generated on the alignment auxiliary coils D1 and D2. According to the magnitude of the induced electromotive force E(E1, E2), it can be judged The mobile terminal may be located at a certain location. Although it is impossible to determine the specific location of the mobile terminal at this time, it can be determined that the mobile terminal may be at one of the four black dots in Figure 2A at this time. According to the mobile terminal at different points , determine the coordinates of the magnitude E(E1, E2) of the electromotive force in the plane four-quadrant simulation coordinate diagram, the first quadrant E(E1, E2), the second quadrant E(-E1, E2) and the third quadrant E(-E1 , -E2) the first quadrant E(E1, -E2), then it can be determined that the coordinate point E corresponding to the offset parameter is displayed in the plane four-quadrant simulation coordinate diagram at this time.

In addition, in the embodiment of the present application, the coordinate axes shown in FIG. 2A may not be displayed, but only the origin corresponding to the preset optimal charging position and the coordinate points corresponding to the offset parameters are displayed. This embodiment of the present application does not Be limited.

In the specific implementation process, the induced electromotive force signal of the alignment auxiliary coil can be monitored by the receiving circuit module, and sent to the CPU (Central Processing Unit, central processing unit) of the mobile terminal for processing. The mobile terminal can control the mobile terminal to generate a planar four-quadrant simulation coordinate diagram with the preset optimal charging position as the origin by sensing the magnitude of the electromotive force, and display the coordinate points corresponding to the offset parameters in the planar four-quadrant simulation coordinate diagram.

Step 240, prompting the user to move the mobile terminal to adjust the coordinate point corresponding to the offset parameter to the origin position.

Then, in order to move the mobile terminal to the preset optimal charging position, the user only needs to move the mobile terminal to offset The coordinate point corresponding to the parameter is adjusted to the origin position. Moreover, in the embodiment of the present application, the real-time offset parameters can be acquired in real time or periodically, and updated and displayed in the plane four-quadrant simulation coordinate diagram, so that the user can be prompted in real time to move the mobile terminal to set the offset parameters corresponding to The coordinate point is adjusted to the origin position.

In the embodiment of the present invention, when the mobile terminal is placed on the wireless charging base, the induced electromotive force of the at least one pair of orthogonally arranged alignment auxiliary coils is obtained; according to the induced electromotive force, the mobile terminal and the The offset parameter of the preset optimal charging position of the wireless charging base; displaying the offset parameter to prompt the user to adjust the mobile terminal to the preset optimal charging position according to the offset parameter. Therefore, the user can be prompted in real time to adjust the mobile terminal to a preset optimal charging position according to the position of the mobile terminal, thereby improving the freedom experience of the mobile terminal during the charging process.

In addition, in the embodiment of the present application, when the at least one pair of orthogonally arranged alignment auxiliary coils is a pair, two alignment auxiliary coils in the pair of orthogonally arranged alignment auxiliary coils may also be The induced electromotive force of the coil represents an offset parameter between the mobile terminal and the preset optimal charging position. And, generate a plane four-quadrant simulation coordinate diagram with the preset optimal charging position as the origin, and display coordinate points corresponding to the offset parameters in the plane four-quadrant simulation coordinate diagram; prompt the user to move the mobile The terminal adjusts the coordinate point corresponding to the offset parameter to the origin position. Therefore, the accuracy of the offset parameter is further improved, and misadjustment by the mobile terminal user is further reduced.

Embodiment Three

A method for prompting the alignment of a wireless charging base provided by an embodiment of the present invention is introduced in detail.

Referring to FIG. 3 , it shows a flowchart of steps of a method for prompting the alignment of a wireless charging base in an embodiment of the present invention.

Step 310, when the mobile terminal is placed on the wireless charging base, the induced electromotive force of the at least one pair of orthogonally arranged alignment auxiliary coils is acquired.

Step 320, when the at least one pair of orthogonally arranged alignment auxiliary coils is two pairs, select the two induced electromotive forces with the largest values from each of the induced electromotive forces, and use the screened induced electromotive forces to characterize the mobile terminal An offset parameter from the preset optimal charging position.

However, if the charging coil includes two pairs of alignment auxiliary coils arranged orthogonally, the structure of the receiving end at this time may be as shown in 3A. Among them, C1, C2, C3, and C4 are alignment auxiliary coils, and C1 and C2 are placed orthogonally, and C3 and C4 are placed orthogonally. Of course, the angle between C1 and C2 and the angle between C3 and C4 can also be adjusted, which is not limited in this embodiment of the present application. When the receiving end of the mobile terminal is connected to the transmitting end, if the centers of the transmitting coil and the receiving coil are aligned, according to the right-hand spiral law, the magnetic induction intensity between coils C1 and C2 cancels each other to the maximum value, and the induced electromotive force is minimum or 0 , the value of the magnetic induction between coils C3 and C4 cancels each other is the largest, and the induced electromotive force is the smallest or 0.

Then, the induced electromotive force obtained at this time includes the induced electromotive force of the four alignment auxiliary coils. At this time, if the induced electromotive force of the four alignment auxiliary coils is used to characterize the offset parameters of the mobile terminal and the preset optimal charging position, then when the coordinate points corresponding to the offset parameters are subsequently determined, it is easy to be unclear. In the embodiment of the present application, it is necessary to screen out the two induced electromotive forces with the largest values from the induced electromotive forces, and use the screened induced electromotive forces to represent the offset parameters between the mobile terminal and the preset optimal charging position.

For example, assuming that the induced electromotive forces of C1, C2, C3 and C4 are 1.0V (volts), 1.5V, 2.0V and 0.5V respectively, then the induced electromotive forces of C2 and C3 can be used to characterize the mobile terminal and the preset best The offset parameter for the charging position. It should be noted that, for the induced electromotive force filtered out by the screening process, it can be assumed that the induced electromotive force of the correspondingly filtered alignment auxiliary coil is zero in subsequent steps.

Step 330, generating a planar four-quadrant simulation coordinate diagram with the preset optimal charging position as the origin, and displaying coordinate points corresponding to the offset parameters in the plane four-quadrant simulation coordinate diagram.

In the embodiment of the present application, since the initially obtained induced electromotive force includes the induced electromotive force of four alignment auxiliary coils, the induced electromotive force obtained after screening may be the induced electromotive force of any two alignment auxiliary coils. Then, in the embodiment of the present application, when the charging coil includes two pairs of orthogonally arranged alignment auxiliary coils, a planar four-quadrant simulation coordinate diagram corresponding to the four pairs is generated with the preset optimal charging position as the origin The induced electromotive force of the auxiliary coil.

For example, for the aforementioned alignment auxiliary coils C1, C2, C3 and C4 in FIG. 3A, the generated planar four-quadrant simulation coordinate diagram with the preset optimal charging position as the origin can be shown in FIG. 3B. Among them, the four rays c, c2, c3 and c4 respectively represent the preset growth directions of the induced electromotive force of the alignment auxiliary coils C1, C2, C3 and C4, and the coordinate origin corresponds to the preset optimal charging position. The origin of the coordinates may also represent the orthogonal center of the alignment auxiliary coils C1 and C2 in FIG. 3A , or the orthogonal center of the alignment auxiliary coils C3 and C4 , which is not limited in this embodiment of the present application.

Then, when the receiving end is placed on the transmitting end, no matter where it is placed, it will be covered on the four alignment auxiliary coils, and the induced electromotive force of the alignment auxiliary coils corresponds to a unique coordinate point E(c1,c2 ,c3,c4). For example, for the induced electromotive forces C2 and C3 obtained after the aforementioned screening, the corresponding position of the mobile terminal in the coordinates shown in Figure 3B is (0, 1.5V, 2.0V, 0), which is the four-quadrant simulation in the plane at this time. The coordinate point corresponding to the offset parameter displayed in the coordinate map. For example, point P in FIG. 3B may represent the coordinate point (0, 1.5V, 2.0V, 0).

When the receiving end of the mobile terminal is placed on the transmitting end at will, no matter where it is placed, it will be covered on the four alignment auxiliary coils, and will correspond to the only coordinate point in the plane four-quadrant analog coordinate diagram, In the specific implementation process, the receiving circuit module can also be used to detect the induced electromotive force signal at this time, and send it to the CPU of the mobile terminal for processing. The mobile terminal obtains the size of the induced electromotive force according to the screening, and displays the coordinate points corresponding to the offset parameters in the generated planar four-quadrant simulation coordinate diagram. In addition, in the embodiment of the present application, in order to intuitively prompt the user to adjust the direction, a corresponding adjustment direction indication can also be added in the plane four-quadrant simulation coordinate diagram, for example, in Figure 3B, an indication arrow is added between point P and the coordinate origin, Indicates the direction of movement. Therefore, the user can adjust the mobile terminal to the preset optimal charging position according to the displayed prompt arrow.

Step 340, prompting the user to move the mobile terminal to adjust the coordinate point corresponding to the offset parameter to the origin position.

In the embodiment of the present invention, when the mobile terminal is placed on the wireless charging base, the induced electromotive force of the at least one pair of orthogonally arranged alignment auxiliary coils is obtained; according to the induced electromotive force, the mobile terminal and the The offset parameter of the preset optimal charging position of the wireless charging base; displaying the offset parameter to prompt the user to adjust the mobile terminal to the preset optimal charging position according to the offset parameter. Therefore, the user can be prompted in real time to adjust the mobile terminal to a preset optimal charging position according to the position of the mobile terminal, thereby improving the freedom experience of the mobile terminal during the charging process.

In addition, in the embodiment of the present application, when the at least one pair of orthogonally arranged alignment auxiliary coils is two pairs, the two induced electromotive forces with the largest values can also be screened out from each of the induced electromotive forces, and obtained by screening The induced electromotive force represents an offset parameter between the mobile terminal and the preset optimal charging position. And, generate a plane four-quadrant simulation coordinate diagram with the preset optimal charging position as the origin, and display coordinate points corresponding to the offset parameters in the plane four-quadrant simulation coordinate diagram; prompt the user to move the mobile The terminal adjusts the coordinate point corresponding to the offset parameter to the origin position. Therefore, the accuracy of the offset parameter is further improved, thereby further reducing misadjustment by the mobile terminal user.
