The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1 to 3, a magnetic screen protection film according to an embodiment of the present invention includes a film body 10, a first magnetic element 21, a second magnetic element 22, an upper shielding layer 31, an upper double-sided adhesive layer 41, a lower shielding layer 32, and a lower double-sided adhesive layer 42; the membrane body is provided with a first edge part 11, a first through groove 15 matched with the shape of the first magnetic part 21 and a second through groove 16 matched with the shape of the second magnetic part 22 are arranged on the first edge part 11, and the first through groove 15 and the second through groove 16 are arranged at intervals and are positioned on the same straight line; the first magnetic part 21 is correspondingly embedded into the first through groove 15, and the second magnetic part 22 is correspondingly embedded into the second through groove 16; the upper shielding layer 31 is adhered to the upper surface of the first edge 11 of the film body 10 through the upper double-sided adhesive layer 41 and covers the first through groove 15 and the second through groove 16; the lower shielding layer 32 is adhered to the lower surface of the first edge 11 of the film body 10 through the lower double-sided adhesive layer 42 and covers the bottoms of the first through groove 15 and the second through groove 16, so that the first magnetic attraction piece 21 and the second magnetic attraction piece 22 are limited in the film body 10 by the upper shielding layer 31 and the lower shielding layer 32.

The film body 10 is rectangular to match with a screen of a covered electronic product, such as a screen of a tablet computer. In this embodiment, the film body 10 is a privacy film. A through hole 110 is formed in the middle of the first edge 11 to correspondingly expose a camera of an electronic product. The first through groove 15 and the second through groove 16 are located on opposite sides of the through hole 110 of the first edge 11. Specifically, the first through groove 15 and the second through groove 16 are respectively provided in a long shape.

The first magnetic element 21 and the second magnetic element 22 may be magnet bars in different embodiments, or may be a metal for magnetic attraction, such as iron sheets. Since magnets are disposed in the screen frame of many electronic products, even if the first magnetic attraction member 21 and the second magnetic attraction member 22 are iron pieces, the magnetic attraction and fixation can be achieved. Specifically, in the present embodiment, the first magnetic attracting element 21 and the second magnetic attracting element 22 are all made of manganese steel sheets.

The thicknesses of the first magnetic attraction piece 21 and the second magnetic attraction piece 22 are both smaller than or equal to the thickness of the film body 10. In this embodiment, the thickness of the film body 10 is 0.33mm, that is, the depth of the first through groove 15 and the second through groove 16 is 0.33mm; the first magnetic attraction piece 21 and the second magnetic attraction piece 22 have a thickness of 0.25mm, so that the first magnetic attraction piece 21 and the second magnetic attraction piece 22 are allowed to be respectively embedded into the first through groove 15 and the second through groove 16 and then do not exceed the upper surface and the lower surface of the film body 10.

The upper shielding layer 31 and the lower shielding layer 32 are both black frosted PC strips. In this embodiment, both ends of the upper and

lower shielding layers

31 and 32 are flush with both ends of the first edge 11 of the film body 10. It is understood that both ends of the upper double-sided adhesive layer 41 and the lower double-sided adhesive layer 42 are flush with both ends of the first edge portion 11 of the film body 10. Because last shielding layer 31 and lower shielding layer 32 are a whole black dull polish PC strip respectively, thereby will first edge portion 11 covers, inhales a piece 21, the second magnetism that will separate simultaneously and inhales a piece 22 to shield, when inhaling a piece 21, the second magnetism and inhale a piece 22 fixed with first magnetism for whole magnetism is inhaled screen protection film beautifully to be able to bear or endure to see.

Since the through hole 110 is formed in the middle of the first edge 11 of the film body 10, through holes (not shown) are formed in the middle of the upper shielding layer 31, the lower shielding layer 32, the upper double-sided adhesive layer 41, and the lower double-sided adhesive layer 42 so as to align with the through hole 110.

In this embodiment, the thicknesses of the upper double-sided adhesive layer 41 and the lower double-sided adhesive layer 42 are both 0.05mm, and the thicknesses of the upper shielding layer 31 and the lower shielding layer 32 are also small. The first magnetic part 21 and the second magnetic part 22 are embedded in the membrane body 10, so that the first magnetic part 21 and the second magnetic part 22 are prevented from being overlapped with the membrane body in thickness, and the overall thickness is reduced; moreover, the upper shielding layer 31 and the lower shielding layer 32 cover the first magnetic element 21 and the second magnetic element 22, respectively, so as to prevent the first magnetic element 21 and the second magnetic element 22 from being exposed to cause an unsightly appearance. It is understood that, in other embodiments, the upper double-sided adhesive layer 41 and the lower double-sided adhesive layer 42 may be provided with elongated slots corresponding to the positions of the first magnetic-attracting element 21 and the second magnetic-attracting element 22, so that the first magnetic-attracting element 21 and the second magnetic-attracting element 22 do not need to contact the upper double-sided adhesive layer 41 and the lower double-sided adhesive layer 42.

In this embodiment, the magnetic screen protection film further includes two self-adsorbing silica gel strips 50, and each of the self-adsorbing silica gel strips 50 is fixed on the lower surface of the film body 10; the film body 10 further comprises a second edge portion 12 and a third edge portion 13 connected with the first edge portion 11, respectively, and the self-adsorbing silicone rubber strip 50 is installed on the end portions of the second edge portion 12 and the third edge portion 13 far away from the first edge portion 11, so that the overall adsorption force of the screen protection film is increased through magnetic attraction. It will be appreciated that the self-adsorbing silica gel strip 50 is a reusable silica gel.

The utility model discloses the screen protection film is inhaled to magnetism that sets up inhales through first magnetism and inhales piece 21, second magnetism and inhale piece 22 and adsorb the screen, repeatedly usable, do not leave the cull, high-efficient environmental protection. Additionally, the utility model discloses a screen protection film will be inhaled to magnetism first magnetism is inhaled piece 21, the embedding of second magnetism piece 22 after the membrane body 10, through last shielding layer 31, go up double-sided adhesive layer 41, shielding layer 32 down, down double-sided adhesive layer 42 will with being connected of membrane body 10 first magnetism is inhaled piece 21 and second magnetism and is inhaled the piece 22 restriction and be in the membrane body 10, the installation is firm to the thickness stack of piece 21, second magnetism piece 22 and membrane body 10 has been inhaled to first magnetism has been avoided.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
