Problems solved by technology

The current wireless charging devices on the market are all one-to-one wireless charging. To realize one-to-many wireless charging, multiple platforms are required for charging.
Moreover, at this stage, wireless charging technology is still concentrated on high-end devices of a few brand products, and its high price makes this technology not yet fully popularized.

specific Embodiment 2

[0021] A universal wireless charging system includes a housing 10, a switch 20, a connecting circuit 30, a charging interface 40 and a control circuit. The components of the control circuit are thin plate structures, and the casing 10 is a plastic film structure. The control circuit is placed on the casing 10 and protected by the plastic casing 10 . 10. The back side of the shell is provided with an adhesive film, and its charging interface 40 uses a USB5V charging interface again, thereby greatly improving the portability of the patent of the present invention. When people use it, they only need to tear off the sticky film, fix it on a certain position such as a table, a coffee table, or directly put it on the table for use. Of course, the present invention can also be directly designed on positions such as coffee table, dining table.

[0022] The patent of the present invention realizes the one-to-many wireless charging function by means of a relatively simple structure and...

Description

technical field [0001] The invention relates to the field of wireless charging devices, in particular to a universal wireless charging system. Background technique [0002] Although the charging technologies of wireless charging mobile phones, wireless charging Bluetooth speakers, or wireless charging tablet computers on the market are relatively complete, they are all independent and specific charging systems for specific devices. Moreover, such devices are often high-end flagship products among similar products, and are expensive. However, few companies have set foot in this field in terms of how to make huge ordinary devices also obtain wireless charging functions and further lower the threshold of wireless charging technology. [0003] Wireless charging technology was originally designed to free people from messy charging cables. However, although the current wireless charging technology frees people from the shackles of charging cables, each device is independent of e...
