Description

   Non-contact inductive charging mouse pad   

The invention relates to a mouse pad, in particular to a non-contact induction charging mouse pad.

The mouse is a very common and commonly used computer input device. It can locate the cursor on the current screen, and operate the screen elements where the cursor passes by using keys and a wheel device. With the progress of the times, the mouse has gradually evolved into a wireless input device to improve the convenience of operation and carrying.

Most current wireless mice use batteries as a source of power. However, they often face the lack of battery or no batteries nearby to prepare them. As a result, wireless mice cannot operate in a timely manner. For workers who must fight against the clock, or heavy users such as e-sports players, etc. It is unacceptable that the mouse loses power at an important moment, and it takes time to replace the battery.

In order to avoid the above situation, some people design a mouse pad with a wireless charging module. Referring to FIGS. 1 and 2, it is a new patent No. M507013 of the Republic of China. This patent discloses a wireless charging mouse pad body and mouse combination, which includes a mouse 3 and a mouse pad body 1.
