Detailed Description

To further understand the present invention, a preferred embodiment is shown in the drawings, and the following detailed description is given:

referring to fig. 2 and 3, a magnetic attraction structure of a back film of a portable electronic device is disclosed, in which a transparent back film 10 is provided as a back plate 11 corresponding to a back cover 2 of a portable electronic device 1, and a plate ring groove 12 corresponding to a position of a wireless charging coil 4 inside the portable electronic device 1 is concavely provided on a side of the back plate 11 away from the back cover 2; a magnetic module 13 is accommodated in the plate ring groove 12, wherein the magnetic module 13 includes: a fixing ring 14, an adhesive layer 15, a magnetic component 16 and a transparent positioning film 17; wherein, one side of the fixed ring 14 facing the plate body ring groove 12 is provided with a ring groove 141, the bottom of the ring groove 141 is provided with the adhesive layer 15, the magnetic attraction component 16 is formed by a plurality of magnetic attraction units 161 arranged in a ring shape and assembled at one side of the adhesive layer 15 departing from the ring groove 141, and the transparent positioning film 17 is adhered and covered at one side of the magnetic attraction component 16 departing from the adhesive layer 15; an external transparent protective film 18 is adhered to the outer side of the back plate 11 to cover the magnetic module 13, and an external printing layer 19 is arranged between the magnetic module 13 and the external transparent protective film 18; an inner printing layer 20 is arranged between the groove bottom of the plate body annular groove 12 and the magnetic suction module 13; by means of the structure, the back cover 2 of the portable electronic equipment 1, the magnetic module 13 and the wireless charger can be protected to have good absorption effect, and the magnetic module 13 can be positioned more firmly.
