Problems solved by technology

However, this detection method has a large error. If the electronic device is placed tilted or interfered by other equipment, the detection result of this detection method will have a large error.
This detection method can only determine the relatively balanced position of the three coils. If the charging efficiency of this position does not meet the basic requirements, the charging efficiency will also decrease and the heat generation will increase.
In addition, the three outer coils will also affect the moving range of the middle transmitting coil, which has space limitations

Embodiment 1

[0058] A wireless charger with automatic positioning for charging includes a housing for supporting all internal mechanisms and providing a charging platform for wireless charging equipment.

[0059] figure 1 It is a specific structural diagram in an embodiment of the present invention, in figure 1 In the shown embodiment, the casing includes an upper shell 11 and a lower shell 12, and the upper shell 11 and the lower shell 12 are fastened and connected. In this embodiment, the lower case 12 is provided with a fastening portion 121 for matching with the upper case 11 , and the upper case 11 is buckled inside the fastening portion 121 . The specific shape and size of the housing can be customized according to needs, and will not be limited here in detail.

[0060] Figure 8 , Figure 9 It is a schematic diagram of the system structure of the present invention. The casing of the present invention is provided with a control module, a position detection module 20 communicating...

Embodiment 2

[0083] Such as figure 1 , Figure 8 , Figure 9 As shown, the difference from the first embodiment is that the housing in this embodiment is also provided with a charging detection module connected to the control module, the charging detection module is used to sense whether there is a device to be charged on the housing, and will sense The results are sent to the control module. The to-be-charged detection module detects whether there is a device to be charged on the casing before performing a charging operation, so as to avoid useless processes in the subsequent detection and charging process.

[0084] Correspondingly, there is a second detection unit connected to the MCU in the control module, and the second detection unit is used to communicate with the charging detection module, send the MCU’s charging detection command to the charging detection module, and send the charging detection module. The detection result of the charging detection module is sent to the MCU.

Embodiment 3

[0089] Such as figure 1 , Figure 8 , Figure 9 As shown, different from the first embodiment, the housing in this embodiment is also provided with a temperature detection module connected to the control module, the temperature detection module is used to detect the temperature of the device to be charged and / or the charging module 30, and The temperature value is fed back to the control module. The temperature detection module is used to regularly or irregularly detect the temperature of the device to be charged and / or the charging module 30, and give an early warning when the temperature of the device to be charged and / or the charging module 30 is higher than the corresponding preset value. The operation of the charger.

[0090] Correspondingly, the control module is provided with a third detection unit connected to the MCU, and the third detection unit is used to communicate with the temperature detection module, send the temperature detection command of the MCU to the t...

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a wireless charger with automatic positioning for charging and a realization method thereof. Background technique [0002] Wireless charging technology (English: Wireless charging technology; Wireless charge technology) is widely used in all walks of life, and wireless chargers are common charging devices in daily life. The wireless charger uses the principle of electromagnetic induction to generate current through the electromagnetic induction between the primary and secondary coils, so as to realize the transmission of energy in the space range, so that the energy is transmitted between the charger and the electric device with a magnetic field, and then realizes Contactless transmission. [0003] When electronic devices such as mobile phones are charged with wireless chargers, due to the uncertainty of their placement, the positions of the receiving coils of differen...
