Background technique

In recent years, due to the development of industry and commerce and the progress of society, the products provided are mainly aimed at convenience, reliability, and economic benefits. Therefore, the products currently developed are more advanced than before, and can contribute to society.

The mouse is a computer input device, which can position the cursor on the screen, and operate the screen elements at the position where the cursor passes through the button and the wheel device. Generally speaking, mice can be roughly divided into wired and wireless mice and wireless mice.

Although the wireless mouse is convenient and does not need to be connected to a computer, the disadvantage of the wireless mouse is that it needs to be powered by a battery, which may suddenly run out of power during important moments of use. Therefore, the battery power consumption of the wireless mouse can affect the user's cost of use. Some wireless mice consume a lot of power, and the batteries need to be replaced frequently. Currently, the service life of batteries on the market is about three months, and using rechargeable batteries can also save costs. In addition, long-term use of the mouse by modern people is also likely to cause carpal tunnel syndrome.

In addition, the wireless charging source technology is to transmit the energy of the wireless charging device to the electric device, and the electric device converts the received energy into electrical energy and stores it in the battery. A magnetic field is used to transmit energy between the charger and the electrical device, and there is no need for exposed conductive interfaces or wire connections. However, the biggest disadvantage is that the wireless charging board still needs to be plugged in, and it cannot be truly wireless.

It can be seen that the above-mentioned existing wireless charging method obviously still has inconvenience and defects, and needs to be further improved. In order to solve the above-mentioned problems, related fields have tried their best to seek a solution, but no applicable method has been developed for a long time. Therefore, how to truly achieve wireless and protect the wrist is one of the current important research and development topics, and it has also become an urgent goal for improvement in related fields.
