As shown in fig. 1 to 8, the protective film 10 of the present embodiment includes a protective layer 11, an adhesive layer 12, and a filler, wherein the adhesive layer 12 is connected to the protective layer 11, the filler is disposed at an edge position of the protective layer 11 and is located at a side of the protective layer 11 to which the adhesive layer 12 is connected, and the filler is used for filling a gap between an edge of the protective film and an edge of a screen of the electronic device 20. In this embodiment, the filling member is disposed at the edge of the protective layer 11 and on the side of the protective layer 11 to which the adhesive layer 12 is attached, so that the gap between the edge of the protective film 10 and the edge of the screen of the electronic device 20 can be filled, thereby reducing dust entering and improving adhesion between the edge of the protective film 10 and the edge of the screen of the electronic device 20.

In an embodiment, for example, as shown in fig. 1 to 8, the protective layer 11 includes a main body 111 and an attaching portion 112, the attaching portion 112 is disposed to protrude outwards along the main body 111, and the attaching portion 112 is located at a middle position of a short side of the main body 111; the filling member includes a first filling member 13, and the first filling member 13 is connected to the fitting portion 112. The slope of the first filling member 13 does not exceed the slope of the screen edge of the electronic device 20, so as to avoid interference between the first filling member 13 and the screen edge of the electronic device 20. It should be noted that, after the protective film 10 is attached to the electronic device 20, the attaching portion 112 corresponds to the earpiece hole of the electronic device 20, so that the filler better protects the earpiece hole from dust entering the earpiece hole.

In an embodiment, for example, as shown in fig. 2, the first filling member 13 includes a bonding surface 131 and a contact surface 132, the first filling member 13 is connected to the bonding portion 112 through the bonding surface 131, and the contact surface 132 is inclined relative to the bonding surface 131 and forms an acute angle with an included angle a formed between the bonding surface 131. Specifically, the angle a formed between the contact surface 132 and the contact surface 131 is in the range of 8 degrees to 15 degrees. More specifically, the adhesive layer 12 includes a void portion 121, and a part of the first filling member 13 is located in the void portion 121. In this embodiment, the first filling member 13 is a wedge-shaped strip. It should be noted that, in other embodiments, the shape of the first filling member 13 is not specifically limited, and the included angle formed by the contact surface 131 and the contact surface 132 in the first filling member 13 is not specifically limited, and according to actual needs, only the first filling member 13 needs to be ensured to fill the gap between the edge of the protective film and the screen of the electronic device 20.

In an embodiment, for example, in this embodiment, as shown in fig. 3, the first filling member 13 includes a bonding surface 131 and a contact surface 132, the first filling member 13 is connected to the bonding portion 112 through the bonding surface 131, and the contact surface 132 is disposed parallel to the bonding surface 131. Understandably, at this time, the first filler 13 is a rectangular bar. As shown in fig. 4, the number of the first fillers 13 is plural, and the plurality of the first fillers 13 are disposed at intervals and are connected to the bonding portion 112. It is understood that, at this time, the first filling member 13 is a rectangular block, and a plurality of the rectangular blocks are arranged in a straight line. When the first filling member 13 is the rectangular bar or the plurality of rectangular blocks, the adhesive layer 12 includes a protrusion 121, and the protrusion 121 covers the first filling member 13 and is connected to the contact surface 132. It is understood that the angle between the contact surface 131 and the contact surface 132 in the rectangular bar is 90 degrees, and the angle between the contact surface 132 and the contact surface 131 in the rectangular block is also 90 degrees. In this embodiment, when the number of the first filling members 13 is plural, the space between the first filling members 13 may increase the sound permeability, which is beneficial to sound transmission.

In an embodiment, for example, as shown in fig. 5, the protective layer 11 further includes an edge portion located around the main body 111, and the filling member further includes a second filling member 14, where the second filling member 14 is connected to the edge portion. Specifically, the first filling member 13 and the second filling member 14 are connected to form a ring-like structure. It should be noted that the slope of the second filling member 14 does not exceed the slope of the screen edge of the electronic device 20, so as to avoid interference between the second filling member 14 and the screen edge of the electronic device 20. It should be noted that, after the protective film 10 is attached to the electronic device 20, the first filling member 13 and the second filling member 14 may not only prevent dust, but also solve the problem that the edge of the protective film 10 is easy to tilt, so that the protective film 10 plays a better role in protecting the electronic device 20. In practical applications, when the protective film 10 includes the first filling member 13 and the second filling member 14, the positions of the adhesive layer 12 corresponding to the first filling member 13 are not particularly limited, as shown in fig. 5 to 8, that is, the positions of the adhesive layer 12 and the first filling member 13 may be raised, may be straightened, may be recessed, or may entirely cover the first filling member 13. In other embodiments, the first filler 13 may also be partially covered.
