for the wireless charger with the two-dimensional adjustment function of the position of the wireless charging magnetic conversion device provided by the embodiment, the specific working principle is as follows: the detection module 13 detects whether the device to be charged exists on the shell 11, and if the device to be charged exists on the shell 11, a feedback signal is sent to the control module 14; the control module 14 is specifically configured to detect a charging state of the device to be charged after receiving the feedback signal, and send a driving signal to the first transmission module when detecting that the device to be charged cannot be charged normally; the first transmission module is used for adjusting the position of the wireless charging magnetic conversion device on the first preset path according to the received driving signal; the control module 14 is further configured to detect a charging state of the device to be charged in real time when the first transmission module adjusts the position of the wireless charging magnetic conversion device on the first preset path; if the device to be charged is detected to be in a charging state, stopping sending the driving signal to the first driving module; if the first transmission module does not detect that the device to be charged is in a charging state after adjusting the wireless charging magnetic conversion device to reciprocate once in the first range on the first preset path (i.e. after sequentially touching the first limiting device and the second limiting device for 1 time), the control module 14 stops sending the driving signal to the first transmission module, changes the direction of the driving signal to the second transmission module, and controls the second transmission module to move for a preset distance along the second preset path through the driving signal; the second transmission module is configured to adjust the wireless charging magnetic conversion device to move a predetermined distance on the second preset path under the control of the control module 14; the control module 14 is further configured to detect a charging state of the device to be charged in real time when the second transmission module is controlled to adjust the wireless charging magnetic conversion device to move on the second preset path; if the device to be charged is detected to be in a charging state, stopping sending the driving signal to the second transmission module; if the control module 14 does not detect that the device to be charged is in a charging state after the second transmission module adjusts the wireless charging magnetic conversion device to move on the second preset path for a predetermined distance, stopping sending the driving signal to the second transmission module, and redirecting the first transmission module to send the driving signal, so that the first transmission module starts to reciprocate on the first preset path again, so that the above operation is performed until the device to be charged can be normally charged or the wireless charging magnetic conversion device cannot be normally charged at all positions on the first preset path and the second preset path;
preferably, the driving signal sent by the control module 14 to the transmission module 15 may be continuous or discontinuous. For example: the control module 14 may send a continuous driving signal for a second predetermined time period to the transmission module 15, for example, send the driving signal to the second transmission module for 1 continuous minute, so that the second motor of the second transmission module continuously rotates within the 1 continuous minute to enable the second transmission assembly to drive the wireless charging magnetic conversion device to continuously move on a preset second preset path for 1 continuous minute, so as to achieve the purpose of moving for a predetermined distance; or, the driving signal sent by the control module 14 to the second transmission module is discontinuous, so that the second transmission assembly drives the wireless charging magnetic conversion device to move step by step on the preset second preset path, for example, the second transmission assembly may further include a plurality of gears arranged on the second preset path, each gear is provided with a limit switch, after the control module 14 sends the driving signal to the second transmission assembly, the second transmission assembly adjusts the wireless charging magnetic conversion device to move for a certain distance, the support member of the wireless charging magnetic conversion device stops moving when contacting the limit switch, at this time, if the actual moving distance of the wireless charging magnetic conversion device on the preset second preset path is smaller than the preset distance, the control module 14 sends the driving signal to the second transmission assembly again to forcibly drive the second transmission assembly to drive the wireless charging magnetic conversion device to move forward continuously, and continuing to judge whether the actual moving distance of the wireless charging magnetic conversion device on a preset second preset path is smaller than a preset distance or not until the next limit switch is touched, and if so, sending a driving signal to the second transmission assembly again, thus the prior art is realized.
In this embodiment, when the wireless charging does not work normally, the control module 14 can send an instruction to the first transmission module, the first support plate is driven by the first transmission module to move, if the wireless charger still does not work normally (i.e. does not match with the device to be charged) in the moving process, the first support plate can touch the first, the second limiting device stops in the original position once and when touching the limiting device for the second time, the control module 14 can output an instruction to the second transmission module to start working, the second transmission module drives the second support plate to stop after moving the predetermined short distance along the second preset path, the control module controls the first transmission module to drive the first support plate to move again, until the wireless charging works normally, the transmission module stops working and keeps the original position. It should be noted that, in this embodiment, the control module 14 controls the operation sequence of the first transmission module and the second transmission module to be interchangeable, that is, controls the wireless charging magnetic conversion device 12 to operate on the second preset path, and if the wireless charging magnetic conversion device 12 does not achieve normal charging after reciprocating one on the second preset path, controls the wireless charging magnetic conversion device 12 to operate on the first preset path for a predetermined distance, and then adjusts the position of the wireless charging magnetic conversion device on the first preset path, and so on.
In an optional example, when the first predetermined path or the second predetermined path is a closed loop, the first limiting device and the second limiting device or the third limiting device and the fourth limiting device may be combined into one.
In an alternative embodiment, for embodiments of the present invention in which the transmission module 15 comprises a first transmission module and/or a second transmission module, the control module 14 may further comprise an alarm device; and the alarm device is used for sending an abnormal working signal, such as an alarm signal, if the charging equipment to be charged still cannot be normally charged is detected after the first transmission module and the second transmission module are controlled to reciprocate back and forth along the first preset path and the second preset path. For example, the alarm device may be one or more of a buzzer, an audio, an indicator light, a shock, a communication signal, and the like. If the transmission module 15 has only one transmission module, after the transmission module completes one reciprocating motion, the device to be charged may still be unable to be charged normally due to the placement reason (for example, the device is placed too close to the side), and at this time, the alarm device starts to work to remind the user; when 2 transmission modules exist, after the 2 transmission modules operate a reciprocating motion, if the wireless charger still cannot work normally, the alarm device starts to work.
To sum up, the embodiment of the utility model provides a pair of wireless charging panel and controlling means thereof treats through the detection whether the battery charging outfit is placed at assigned position or whether the perception user input signal instruction, by the operating condition of the corresponding control drive module of control module to the realization is according to the wireless magnetism conversion equipment that charges of being battery charging outfit adjustment wireless charger in order to reach the purpose that automatic seeking can normal wireless charging position, the utility model discloses can the wireless position of charging magnetism conversion equipment that charges of intelligent control, simple and practical, the interactivity is strong, uses to experience, operating efficiency is high.
