Abstract

The invention discloses a wireless charging receiving terminal, which is used for solving the problem that the thermal resistance of the interface between the double-sided glue, the magnetic conductive module and the substrate in wireless charging receiving terminal in the prior art is large, thereby affecting the heat dissipation of the whole module. The wireless charging receiving end comprisesa magnetic permeability module, a coil and a substrate, wherein, one end of the coil is arranged on the substrate; the magnetic conductive module has a magnetic conductive substrate, and a protrusionprotruded from the middle of the magnetic conductive substrate, the magnetic conductive substrate has a coil curing region surrounding the protrusion; the coil curing region is bonded and fixed in theother end, opposite to the substrate, of the coil; the protrusion extends into the middle of the coil and is adhered and fixed on the substrate.

Description

technical field [0001] The present invention relates to the technical field of wireless charging, in particular to a wireless charging receiving end. Background technique [0002] With the rapid development of smart mobile terminals, the wireless charging technology applied to smart mobile terminals has gradually become the technical commanding heights that many high-tech companies compete for. Among them, the electromagnetic induction wireless charging technology has become the best choice for smart mobile terminals due to its lower development and production costs, higher charging efficiency and better miniaturization design. [0003] In order to improve the charging efficiency of electromagnetic induction wireless charging, a magnetically permeable material with high magnetic permeability is usually used as a magnetically permeable module. At present, the receiving end of the wireless charging of the smart mobile terminal usually adopts figure 1 The structure shown incl...
