Abstract
A rigid wireless charging mouse pad includes a rigid board layer, a double-sided adhesive plate and a coil. The underside of the rigid board layer has a single-ring groove with an inner top groove wall. The double-sided adhesive plate is adhered to the inner top groove wall. The coil has surrounding rings arranged side by side with one another to form a coil module which is stacked on the double-sided adhesive plate in the single-ring groove and adhered by the double-sided adhesive plate to achieve a wireless charging effect by the mouse pad in the condition of having only one single-ring groove on the rigid board layer, so as to achieve the effects of reducing manufacturing difficulty, lowering manufacturing cost, and improving market competitiveness.
