Illustratively, the rail 17 may be mounted below the table top, and the rail 17 may be S-shaped or in a back-shape. The slider may be a slider which may be embedded in the track so that a sliding connection with the track may be achieved. The charging base 13 can move in the box body 11 on one hand and further can move along with the box body 11, so that the movable range of the charging base 13 is enlarged, and the area of a wireless charging area on a desktop is correspondingly enlarged.
In the present disclosure, the wireless charging box 1 may be used alone or in combination with other wireless charging boxes 1. Further, in the present disclosure, a communication interface is disposed on the case 11, and the communication interface is electrically connected to the displacement mechanism 14; the communication interface is electrically connected to another wireless charging box 1 to interact communication signals with the other wireless charging box 1.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a detection plate according to an embodiment. In an embodiment, the detecting board 12 includes a substrate 121 and a plurality of magnetic sensors 122 distributed on the substrate 121, where the magnetic sensors 122 are used to detect the position of the device 4 to be charged on the supporting platform 3. The substrate 121 may be a PCB board herein. The substrate 121 may be a single PCB board or may be formed by combining a plurality of PCB boards.
The magnetic sensor 122 may be a magneto-resistive sensor, a hall sensor, or the like, which is capable of reacting to magnetic field changes. In one example, in order to improve the accuracy of detecting the position of the device 4 to be charged, a magnetoresistive sensor is employed.
The magnetic sensor 122 adopted in the embodiment can efficiently determine the position of the wireless receiving coil in the equipment 4 to be charged, so that the time for traversing the charging base 13 to detect the position of the receiving coil can be saved, and the influence of redundant heat energy generated when the optimal charging position is found on the stability of the charging base 13 is avoided. The position of the receiving coil is determined in a physical mode, so that a software algorithm can be prevented from being used for processing feedback signals in the wireless charging process, and the risk of algorithm processing errors is reduced; therefore, when determining the charging position, the embodiment does not need to communicate with the charging base 13 and the device to be charged 4, does not need to occupy a communication channel, and saves the communication resources of the device to be charged 4 and the wireless charging module.
In particular, during operation, a holster can be sleeved on the device to be charged 4, and one or more magnetic elements are arranged on the holster. When a plurality of magnetic pieces are provided, the plurality of magnetic pieces may be provided corresponding to four corners of the device 4 to be charged; when one magnetic member is provided, the magnetic member may be provided corresponding to the position of the center or the receiving coil of the device 4 to be charged.

The arrangement of the magnetic members on the substrate 121 may be uniform or non-uniform. In one embodiment, in order to improve the accuracy of detecting the placement position of the device to be charged 4, a plurality of magnetic sensors 122 are disposed in an array on the substrate 121.
In one example, two adjacent magnetic sensors 122 are arranged 2cm apart in the lateral direction, and two adjacent magnetic sensors 122 are also arranged 2cm apart in the longitudinal direction. When the length and width of the charging support platform 3 is 350mm×350mm, 17×17 magnetic sensors 122 are required.
After the controller 15 determines the position of the device 4 to be charged according to the detection result of the magnetic sensor 122, the controller 15 sends a control signal to the displacement mechanism 14 to control the distance that the displacement mechanism 14 needs to move. The displacement mechanism 14 is used for bearing the charging base 13 to move to a proper position, so that the charging base 13 can be aligned with the equipment 4 to be charged, and effective wireless charging is ensured.
Referring to fig. 6 to 8, fig. 6 is a schematic side view of an interior of a wireless charging box according to an embodiment; fig. 7 is a schematic view illustrating the structure of the inside of the wireless charging cartridge according to fig. 6, and fig. 8 is another view from the perspective of fig. 7.

The driving circuit module 143 is electrically connected to the controller 15, so as to receive a control signal sent by the controller 15, and drive the first driving motor 1431 and the second driving motor 1432 to work according to the control signal. The first guide rail 141 is disposed on the second guide rail 142, and the first driving motor 1431 is used to drive the first guide rail 141 to move along the second guide rail 142; the charging base 13 is disposed on the first rail 141, and the second driving motor 1432 is used to drive the charging base 13 to move along the second rail 142.
The driving circuit module 143 includes a signal processing and amplifying circuit to process and amplify the control signal sent from the controller 15. The signals processed by the driving circuit module 143 can drive the first driving motor 1431 and the second driving motor 1432 to move.
The first rail 141 and the second rail 142 may be at 90 ° to each other. The first rail 141 and the second rail 142 are positioned and length-set to enable the movable range of the charging base 13 to substantially cover the wireless charging area corresponding to the wireless charging area on the support platform 3.
In an example, the first rail 141 may be fixedly disposed on the support plate 2 of the table body 21, and a sliding bar corresponding to the second rail 142 may be provided on the first rail 141 so that the first rail 141 can slide along the second rail 142. The first driving motor 1431 is used to drive the first rail 141 to slide.
Similarly, the charging base 13 is provided with a sliding bar corresponding to the first rail 141, so that the charging base 13 can slide along the first rail 141. The second driving motor 1432 is used to drive the first rail 141 to slide.
After reading the detection result of the magnetic sensor 122, the controller 15 determines the center position of the device 4 to be charged or the position of the receiving coil according to the detection result. In an example, the magnetic pieces are disposed at four corners of the device to be charged 4, and the controller 15 calculates the center position of the device to be charged 4 or the coordinates corresponding to the receiving coil according to the positions of the magnetic pieces disposed at the four corners of the device to be charged 4 and a preset algorithm, and then determines the distance and the movement track of the charging base 13 to be moved after obtaining the coordinates of the current charging base 13.
In an embodiment, the wireless charging module may further include a power supply unit 16, and the wireless charging module further includes the power supply unit 16, where the power supply unit 16 is electrically connected to the controller 15, the displacement mechanism 14, and the charging base 13 to supply power to the controller 15, the displacement mechanism 14, and the charging base 13.
In an example, the power supply unit 16 may have a power supply interface and a power supply processing circuit. When the wireless charging module works, a power supply is connected to the wireless charging module through a power supply interface, and the wireless charging module supplies power to the controller 15, the shifting mechanism 14 and the charging base 13 after the power supply is processed through a power supply processing circuit.
In another example, the power supply unit 16 may also include a battery so that the wireless charging module may still be able to wirelessly charge the electronic device with the power of the battery without having access to mains power.
According to the technical scheme, the wireless charging box 1 is arranged below the supporting platform 3 or on the hidden surface of the supporting platform 3, so that a power supply circuit of the wireless charging box 1 does not need to appear above the supporting platform 3, the wireless charging box 1 can be prevented from appearing on various supporting platforms 3, and the additional increase of visual burden and cleaning burden to a user is avoided.
Moreover, the detection plate 12 and the displacement mechanism 14 are arranged in the wireless charging box 1, so that when the wireless charging box 1 is arranged on one side of the supporting platform 3, the position of the equipment 4 to be charged on the other side of the supporting platform 3 can be detected through the detection plate 12, and the charging base 13 is moved to the position corresponding to the equipment 4 to be charged through the displacement mechanism 14, so that the equipment 4 to be charged is charged, a user does not need to manually align the position of the wireless charging box 1 or the equipment 4 to be charged, and the convenience of wireless charging and the area on the supporting platform 3 for wireless charging are improved.
