When the first driving gear 302 reaches the end of the first rack 303, the first limiting device 310 brakes the first motor 301. At this time, since the first motor 301 cannot continue to rotate, it will stay at the current position or move in the opposite direction according to the drive signal instruction of the control module 14; or when the first motor 301 rotates in the reverse direction to drive the first motor 301 The support plate travels in the negative direction of the X axis.

The position of the path; the control module 14 is also used to detect the 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 When it is detected that the device to be charged is in the charging state, stop sending the drive signal to the first transmission module; if the first transmission module adjusts the wireless charging magnetic conversion device to be on the first preset path After reciprocating once within the first range (that is, after hitting the first and second limiting devices one time in succession), if the device to be charged has not been detected to be in the charging state, the control module 14 stops moving to the first A transmission module sends the driving signal, and then sends a driving signal to the second transmission module, and controls the second transmission module to move a predetermined distance along the second preset path through the driving signal; the second transmission module, It is used 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 also used to control the second transmission module to adjust the wireless When the charging magnetic conversion device moves on the second preset path, it detects the charging state of the device to be charged in real time; if it detects that the device to be charged is in the charging state, it stops sending all data to the second transmission module. The driving signal; if the second transmission module adjusts the wireless charging magnetic conversion device to move a predetermined distance on the second preset path, the control module 14 has not detected that the device to be charged is in a charging state, then Stop sending the driving signal to the second transmission module, and send the driving signal to the first transmission module instead, so that the first transmission module starts to reciprocate on the first preset path again, and so on until it is to be charged The device can be charged normally or the wireless charging magnetic conversion device cannot be charged normally 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 of a second predetermined duration to the transmission module 15, for example, send a driving signal to the second transmission module for 1 minute continuously, and the second motor of the second transmission module will be in the first 1 minute. Inside, keep rotating so that the second transmission assembly drives the wireless charging magnetic conversion device to continuously move on the preset second preset path for 1 minute to achieve the purpose of moving the preset distance; or, the control module 14 transmits to the second The drive signal sent by the module is non-continuous, enabling the second transmission component to drive the wireless charging magnetic conversion device to move stepwise on a preset second preset path. For example, the second transmission component may also include a second preset path. Set multiple gear positions on the path, and set a limit switch for each gear position. After the control module 14 sends a drive signal to the second transmission assembly, the second transmission assembly adjusts the wireless charging magnetic conversion device to move a certain distance. The support of the conversion device will stop moving when it touches the limit switch. At this time, if the actual movement distance of the wireless charging magnetic conversion device on the preset second preset path is less than the preset distance, the control module 14 will move to the second transmission assembly. Send the driving signal again to forcibly drive the second transmission assembly to drive the wireless charging magnetic conversion device to move forward until it hits the next limit switch, and then continue to determine whether the wireless charging magnetic conversion device is on the preset second preset path Whether the actual moving distance is less than the predetermined distance, if so, the driving signal is sent to the second transmission assembly again, as in the past.

In this embodiment, when the wireless charging is not working normally, the control module 14 will issue a command to the first transmission module, and the first support plate will move under the drive of the first transmission module. If the wireless charger is still not working properly during the movement, Work (that is, it is not matched with the equipment to be charged), the first support plate will touch the first and second limit devices once and stay in the original position when it touches the limit devices for the second time. At this time, the control module 14 will Output instructions to the second transmission module to start working. The second transmission module drives the second support plate to move a predetermined short distance along the second preset path and then pauses. The control module then controls the first transmission module to drive the first support plate to move until the wireless The charging works normally, the transmission module stops working and keeps the original position. It is worth noting that in this embodiment, the operating sequence of the control module 14 controlling the first transmission module and the second transmission module can also be interchanged, that is, the wireless charging magnetic conversion device 12 is controlled to run on the second preset path first. If a reciprocating movement on the second preset path fails to achieve normal charging, the wireless charging magnetic conversion device 12 is controlled to run a predetermined distance on the first preset path, and then its position on the first preset path is adjusted. , So repeatedly.

In an optional example, when the first preset path or the second preset path is a closed loop, the first and second limiting devices or the third and fourth limiting devices may also be combined into one .

In an optional embodiment, for the embodiment of the present invention in which the transmission module 15 includes the first transmission module and/or the second transmission module, the control module 14 may also include an alarm device; the alarm device is used for After controlling the first transmission module and the second transmission module to move back and forth along the first preset path and the second preset path, if it is detected that the device to be charged still cannot be charged normally, an abnormal working signal is issued , Such as issuing an alarm signal. For example, the alarm device may be one or more of buzzer, audio, indicator light, vibration, communication signal, etc. If the transmission module 15 has only one transmission module, after the transmission module completes a reciprocating movement, the equipment to be charged may still not be charged normally due to placement reasons (such as being placed too close to the side). At this time, the alarm device starts to work to remind the user; When there are two transmission modules, after both of the two transmission modules run a reciprocating motion, if the wireless charger still does not work normally, the alarm device starts to work.

In summary, the wireless charging board and its control device provided by the embodiments of the present utility model detect whether the device to be charged is placed in a designated position or sense whether the user inputs a signal instruction, and the control module controls the operation of the transmission module accordingly. State, so as to realize the adjustment of the wireless charging magnetic conversion device of the wireless charger according to the charged equipment to achieve the purpose of automatically finding a normal wireless charging position.
