Technical Field

[0001] The present invention relates to the technical field of wireless reverse charging of smart locks, and in particular to a method and device for positioning a position of wireless reverse charging, a smart lock and a storage medium. Background Art

[0002] The wireless reverse charging coil and the charging coil on the smart lock are both placed on a large plane, and a mobile phone is usually used for wireless reverse charging. Due to the non-fixed size of the mobile phone and the position of the coil, it is impossible to uniformly limit the structure in the coil area on the smart lock, resulting in the two coils being inaccurately aligned. In the existing solution, the charging coil in the smart door lock is fixed, and the position of the mobile phone needs to be constantly adjusted during reverse charging to find the best charging position. However, since the user needs to hold the mobile phone for a certain period of time during reverse charging, it is easy to get tired after holding it for a long time, and it is not convenient for the user to handle other things. In addition, holding the mobile phone for a long time cannot keep the mobile phone in the best charging position, resulting in low charging efficiency. Summary of the invention

[0003] In view of this, the present invention provides a wireless reverse charging position positioning method, device, smart lock and storage medium to solve the problem that the mobile phone cannot maintain the optimal charging position, resulting in low charging efficiency and requiring the user to hold the mobile phone for a long time, resulting in a poor user experience.

[0004] In a first aspect, the present invention provides a wireless reverse charging position positioning method, which is applied to a smart lock, wherein a movable charging terminal bracket is installed on the smart lock, wherein the charging coil on the smart lock generates induction with the wireless reverse charging coil of the charging terminal placed on the charging terminal bracket, and the method comprises: obtaining the induced current sensed by the charging coil on the smart lock to the wireless reverse charging coil of the charging terminal placed on the charging terminal bracket; judging whether the induced current is less than a preset induced current threshold; if the induced current is less than the preset induced current threshold, adjusting the position of the movable charging terminal bracket until the induced current is not less than the preset induced current threshold.

[0005] The wireless charging position positioning method provided by the present invention is applied to a smart lock, wherein a movable charging terminal bracket is installed on the smart lock, and the charging coil on the smart lock generates induction with the wireless reverse charging coil of the charging terminal placed on the charging terminal bracket to obtain the induced current, and judge whether the induced current is less than a preset induced current threshold value; if the induced current is less than the induced current threshold value, the position of the movable charging terminal bracket can be adjusted until the induced current is not less than the induced current threshold value, thereby ensuring that the subsequent charging terminal bracket is maintained at the optimal charging position, thereby improving the charging efficiency of the smart lock, and eliminating the need for the user to hold the charging terminal, thereby improving the user experience.

[0006] In an optional embodiment, a magnet is attached to the center of the wireless reverse charging coil of the charging terminal, and a plurality of Hall devices are distributed on the charging coil on the smart lock. The Hall devices sense the magnetic field generated by the magnet and output signals. Adjusting the position of the movable charging terminal bracket includes: obtaining the signal values ​​output by each Hall device respectively, and comparing the signal values; controlling the movable charging terminal bracket to move in the direction of the Hall device with the smallest output signal value.

[0007] A plurality of Hall devices are distributed at various positions of the charging coil of the present invention. The Hall devices sense the magnet on the reverse charging coil and output a signal value, and then based on the signal value, the charging terminal bracket is controlled to move in the direction of the Hall device with the smallest output signal value, thereby achieving targeted and directional adjustment of the position of the charging terminal bracket, reducing the time for adjusting the position of the mobile terminal bracket, and thereby improving the charging efficiency.

[0008] In an optional embodiment, a plurality of Hall devices are distributed on the outer circle of the charging coil on the smart lock, and a plurality of Hall devices are distributed on the inner circle of the charging coil. A magnet is attached to the center of the wireless reverse charging coil of the charging terminal. The Hall device senses the magnetic field generated by the magnet and outputs a signal. The adjustment of the position of the movable charging terminal bracket includes: obtaining the signal value output by all the Hall devices distributed on the outer circle and inner circle of the charging coil; determining whether the signal value output by the first Hall device distributed on the outer circle of the charging coil is greater than the signal value output by all the Hall devices distributed on the inner circle of the charging coil; if the signal value output by the first Hall device distributed on the outer circle of the charging coil is greater than the signal value output by all the Hall devices distributed on the inner circle of the charging coil, controlling the movable charging terminal bracket to move in the opposite direction of the position of the first Hall device.

[0009] The present invention is designed to have multiple Hall devices distributed on the outer ring and the inner ring of the charging coil.

[0011] If the present invention determines that the signal value output by any Hall device distributed in the outer circle of the charging coil is not greater than the signal value output by all Hall devices distributed in the inner circle of the charging coil, the charging terminal can be driven to move in the direction of the Hall device with weaker output signal value, thereby ensuring that the mobile phone charging coil and the door lock reverse charging coil overlap, thereby improving the charging efficiency.

[0012] In an optional embodiment, the method further includes: if the signal values ​​output by the Hall devices distributed in the inner circle of the charging coil are consistent, it indicates that the movement of the charging terminal bracket is completed, and the wireless reverse charging of the smart lock by the charging terminal is started.

[0013] The present invention starts the wireless reverse charging of the smart lock by the charging terminal only when it is determined that the signal values ​​output by the Hall devices distributed in the inner circle of the charging coil are consistent, thereby ensuring the charging efficiency of the smart lock.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] The wireless reverse charging coil and the charging coil on the smart lock are both placed on a large plane, and a mobile phone is usually used for wireless reverse charging. Due to the unstable size of the mobile phone and the position of the coil, it is impossible to uniformly limit the coil area on the smart lock, resulting in inaccurate alignment of the two coils.

[0032] In the prior art, other wireless reverse charging devices will add a silk screen that radiates from small to large on the appearance of the device to indicate the position, but the silk screen is usually printed in the same color, and the size and density of the silk screen cannot reflect the difference well. The actual experience cannot clearly identify the specific position, and the appearance is not beautiful. In addition, the charging coil position in the existing smart door lock is fixed, and the position of the mobile phone needs to be constantly adjusted to find the best charging position during reverse charging. And because the user needs to hold the mobile phone for a certain period of time during reverse charging, it is easy to get tired after holding it for a long time, and it is not convenient for the user to handle other matters. Moreover, if the mobile phone is held for a long time, the mobile phone cannot always be kept in the best charging position, resulting in low charging efficiency.

[0033] According to an embodiment of the present invention, an embodiment of a wireless reverse charging position positioning method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0034] In this embodiment, a wireless reverse charging position positioning method is provided, which is applied to a smart lock. A movable charging terminal bracket is installed on the smart lock, wherein the charging coil on the smart lock generates induction with the wireless reverse charging coil of the charging terminal placed on the charging terminal bracket; the embodiment of the present invention does not limit the charging terminal, which can be a mobile phone, a wireless charger, or other device that can provide wireless charging. Taking the charging terminal as an example, the smart lock has an adjustable bracket for fixing the mobile phone, and the mobile phone bracket is connected to the driving motor inside the smart lock. The position of the mobile phone bracket can be adjusted by controlling the driving motor. When in use, the user can touch a specific button on the front panel of the smart lock or manually open the mobile phone bracket, and place the mobile phone on the bracket. The wireless charging coil integrated in the smart lock can generate induction with the wireless reverse charging coil started by the mobile phone to start charging. This is just an example. Figure 1is a flow chart of a method for positioning a wireless reverse charging position according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0035] Step S101, obtaining the induced current of the wireless reverse charging coil of the charging terminal placed on the charging terminal bracket sensed by the charging coil on the smart lock.

[0036] When the mobile phone holder of the embodiment of the present invention is in the initial position of the smart lock, the mobile phone is placed on the mobile phone holder, such as Figure 2 As shown, the wireless charging coil on the smart lock can sense and obtain the wireless reverse charging induced current a1 of the mobile phone placed on the mobile phone holder.

[0037] Step S102, determining whether the induced current is less than a preset induced current threshold.

[0038] The embodiment of the present invention can compare the induced current a1 with the preset induced current threshold to determine whether the obtained wireless reverse charging induced current is less than the preset induced current threshold, wherein the method for setting the preset induced current threshold is not limited. For example, the induced current threshold A can be set when the smart lock leaves the factory based on factors such as the wire diameter, number of turns and material of the charging coil, as an example only.

[0039] Step S103: if the induced current is less than the preset induced current threshold, adjust the position of the movable charging terminal bracket until the induced current is not less than the preset induced current threshold.

[0040] In the embodiment of the present invention, if it is determined that the induced current a1 is less than the preset induced current threshold A, it means that the coils of the two do not overlap well and the charging efficiency is low. Then, the driving motor can be controlled to adjust the position of the mobile phone holder, and the induced current can be obtained in real time until the induced current is not less than the preset induced current threshold, and the charging operation is started. The method for adjusting the position of the mobile phone holder is not limited. For example, the driving motor can randomly adjust the position of the mobile phone holder based on its own adjustable movable range, or can move the position of the mobile phone holder in the opposite direction of the specific position based on the specific position of the mobile phone holder within the adjustable movable range. This is only an example.

[0041] The wireless charging position positioning method provided by the present invention is applied to a smart lock, wherein a movable charging terminal bracket is installed on the smart lock, and the charging coil on the smart lock generates induction with the wireless reverse charging coil of the charging terminal placed on the charging terminal bracket to obtain the induced current, and judge whether the induced current is less than a preset induced current threshold value; if the induced current is less than the induced current threshold value, the position of the movable charging terminal bracket can be adjusted until the induced current is not less than the induced current threshold value, thereby ensuring that the subsequent charging terminal bracket is maintained at the optimal charging position, thereby improving the charging efficiency of the smart lock, and eliminating the need for the user to hold the charging terminal, thereby improving the user experience.

[0042] In this embodiment, a wireless reverse charging location positioning method is provided, which is applied to a smart lock. A movable charging terminal bracket is installed on the smart lock, wherein the charging coil on the smart lock generates induction with the wireless reverse charging coil of the charging terminal placed on the charging terminal bracket. Figure 3 is a flow chart of a method for positioning a wireless reverse charging position according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0043] Step S301, obtaining the induced current of the wireless reverse charging coil of the charging terminal placed on the charging terminal bracket induced by the charging coil on the smart lock. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0044] Step S302, determine whether the induced current is less than a preset induced current threshold. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0045] Step S303: if the induced current is less than the preset induced current threshold, adjust the position of the movable charging terminal bracket until the induced current is not less than the preset induced current threshold.

[0046] Specifically, a magnet is attached to the center of the wireless reverse charging coil of the charging terminal, and a plurality of Hall devices are distributed on the charging coil of the smart lock. The Hall devices sense the magnetic field generated by the magnet and output a signal. The above step S303 includes:

[0047] Step S3031, obtaining the signal values ​​output by each Hall device respectively, and comparing the signal values.

[0048] Step S3032, controlling the movable charging terminal bracket to move toward the direction of the Hall device with the smallest output signal value.

[0049] like Figure 4As shown, the charging terminal of the mobile phone in the embodiment of the present invention has a magnet inside, which is attached to the center of the reverse charging coil. A plurality of Hall devices are distributed on the charging coil of the smart lock, wherein the number of Hall devices is not limited, and there are at least two or more, which can be randomly distributed on the charging coil or evenly distributed in various directions of the charging coil. The Hall device can sense the magnetic field generated by the magnet and output a signal. For example only, the signal values ​​output by each Hall device can be obtained and compared. When the signal value output by a certain Hall device is weak, indicating that the reverse charging coil of the charging terminal corresponding to the position is not covered, the movable mobile phone holder can be controlled to move in the direction of the Hall device with the weaker output signal value. If the signal values ​​output by each Hall device are relatively uniform, it indicates that the position movement of the mobile phone holder is completed.

[0050] A plurality of Hall devices are distributed at various positions of the charging coil of the present invention. The Hall devices sense the magnet on the reverse charging coil and output a signal value, and then based on the signal value, the charging terminal bracket is controlled to move in the direction of the Hall device with the smallest output signal value, thereby achieving targeted and directional adjustment of the position of the charging terminal bracket, reducing the time for adjusting the position of the mobile terminal bracket, and thereby improving the charging efficiency.

[0051] Specifically, a plurality of Hall devices are distributed on the outer circle of the charging coil on the smart lock, and a plurality of Hall devices are distributed on the inner circle of the charging coil. A magnet is attached to the center of the wireless reverse charging coil of the charging terminal. The Hall device senses the magnetic field generated by the magnet and outputs a signal to adjust the position of the movable charging terminal bracket, including: obtaining the signal value output by all the Hall devices distributed on the outer circle and inner circle of the charging coil; determining whether the signal value output by the first Hall device distributed on the outer circle of the charging coil is greater than the signal value output by all the Hall devices distributed on the inner circle of the charging coil; if the signal value output by the first Hall device distributed on the outer circle of the charging coil is greater than the signal value output by all the Hall devices distributed on the inner circle of the charging coil, controlling the movable charging terminal bracket to move in the opposite direction of the position of the first Hall device.

[0052] The outer ring of the charging coil on the smart lock of the embodiment of the present invention is distributed with multiple Hall devices, and the inner ring of the charging coil is also distributed with multiple Hall devices, such as Figure 5 As shown, taking the example of four Hall devices evenly distributed in all directions of the outer ring and the inner ring, the outer ring is distributed with H1-H4 Hall devices, and the inner ring is distributed with h1-h4 Hall devices. After obtaining the magnetic field generated by the induction magnets of all Hall devices, the output signal value is as follows: Figure 6As shown, it is determined whether the signal value output by any Hall device distributed in the outer circle of the charging coil is greater than the signal value output by all Hall devices distributed in the inner circle of the charging coil, such as whether the signal value output by H1 or H2 or H3 or H4 is greater than the signal value output by all Hall devices h1-h4. If the signal value output by H1 is greater than the signal value output by all Hall devices h1-h4, the movable charging terminal bracket is controlled to move toward the inner circle, that is, to move in the opposite direction of the position of the first Hall device, such as adjusting the charging terminal bracket to move right and downward, for example only.

[0053] The present invention is designed to have multiple Hall devices distributed on the outer ring and the inner ring of the charging coil. If the signal output by the Hall device in the outer ring is greater than the signal output by all the Hall devices in the inner ring of the coil, the charging terminal bracket is controlled to move in the opposite direction of the position of the Hall device in the outer ring, thereby improving the accuracy and efficiency of the positioning of the charging terminal bracket.

[0054] In an optional embodiment, if the signal value output by any Hall device distributed in the outer circle of the charging coil is not greater than the signal value output by all the Hall devices distributed in the inner circle of the charging coil, it is determined whether the signal values ​​output by all the Hall devices distributed in the inner circle of the charging coil are consistent; if the signal values ​​output by the Hall devices distributed in the inner circle of the charging coil are inconsistent, the movable charging terminal bracket is controlled to move in the direction of the Hall device with the smallest output signal value.

[0055] like Figure 6 As shown, in the embodiment of the present invention, if it is determined that the signal value output by any Hall device distributed in the outer circle of the charging coil is not greater than the signal value output by all the Hall devices distributed in the inner circle of the charging coil, it can be determined whether the signal values ​​output by all the Hall devices distributed in the inner circle of the charging coil are consistent. If the signal values ​​output by the Hall devices distributed in the inner circle of the charging coil are inconsistent, the driving motor can be started to drive the charging terminal bracket to move in the direction of the Hall device with the smallest output signal value.

[0056] If the present invention determines that the signal value output by any Hall device distributed in the outer circle of the charging coil is not greater than the signal value output by all Hall devices distributed in the inner circle of the charging coil, the charging terminal can be driven to move in the direction of the Hall device with weaker output signal value, thereby ensuring that the mobile phone charging coil and the door lock reverse charging coil overlap, thereby improving the charging efficiency.

[0057] In an optional implementation, if the signal values ​​output by the Hall devices distributed in the inner circle of the charging coil are consistent, it indicates that the movement of the charging terminal bracket is completed, and the wireless reverse charging of the smart lock by the charging terminal is started.

[0058] like Figure 6As shown, if it is determined in the embodiment of the present invention that the signal values ​​output by the Hall devices distributed in the inner circle of the charging coil are consistent, indicating that the movement of the charging terminal bracket is completed, the current position of the charging terminal bracket can be maintained, and the wireless reverse charging of the charging terminal to the smart lock can be started.

[0059] The present invention starts the wireless reverse charging of the smart lock by the charging terminal only when it is determined that the signal values ​​output by the Hall devices distributed in the inner circle of the charging coil are consistent, thereby ensuring the charging efficiency of the smart lock.

[0060] In this embodiment, a smart lock is also provided. Figure 7 As shown, the smart lock includes a movable charging terminal bracket, a driving motor and a controller. The charging coil on the smart lock generates induction with the wireless reverse charging coil of the charging terminal placed on the charging terminal bracket. The controller controls the driving motor to adjust the position of the movable charging terminal bracket. The controller includes a memory and a processor. The memory and the processor are communicatively connected to each other. Computer instructions are stored in the memory. The processor executes the computer instructions to execute the above-mentioned wireless reverse charging position positioning method.

[0061] In a specific embodiment, Figure 8 As shown, a charging terminal bracket is installed on the smart door lock, and the position of the charging terminal bracket is adjusted by starting the drive motor. Specifically, the drive motor includes two drive motors, which respectively control the horizontal and vertical movement of the charging terminal bracket.
