Generally, the lens 10 of the electronic device protrudes out of the housing of the electronic device, the lens film assembly 20 of the present invention is a surface film for the lens 10 of the electronic device, and forms a protection for the lens 10. In the illustrated embodiment, the lens film assembly 20 of the present invention is specifically described by taking a mobile phone as an example. It should be understood that the lens film assembly 20 may also be used for protecting the lens of other electronic devices, such as a flat panel. The profile of the lens 10 will vary from electronic device to electronic device, but generally the outer surface 12 of the lens 10 will have a size slightly smaller than the size of the peripheral side 14 of the lens 10. It should be noted that: the outer surface 12 of the lens 10 described herein refers to the side of the lens 10 facing the outside, and is generally the surface of the outermost lens of the lens 10, that is, the position of the lens 10 that needs to be protected by a film; the circumferential side 14 of the lens 10 described herein refers to the wall of the lens 10 surrounding its lens.

The outer surface 12 of the lens 10 is preferably a smooth plane, and the outer shape may be circular, square, oval, racetrack, etc., which may vary according to the type and model of the electronic product. The circumferential side 14 of the lens 10 is generally annular and has the same shape as the outer surface 12, but has a slightly larger size than the outer surface. The dimensional difference between the circumferential side surface 14 and the outer surface 12 can be formed in various ways, such as in the embodiment shown in fig. 6, the junction of the circumferential side surface 14 and the outer surface 12 is chamfered, so that the outer surface 12 is slightly reduced relative to the circumferential side surface 14; or, as in the embodiment shown in fig. 8, the peripheral side surface 14' itself is a tapered surface with a certain inclination, the size of which increases gradually in the direction away from the outer surface 12; in another embodiment, the circumferential side 14' itself is a structure with a small outer end and a large inner end, and the like, and is not limited to a specific embodiment.

As shown in fig. 1 to 3, the lens film assembly 20 includes a positioning frame 22, a protection film 24 disposed in the positioning frame 22, and a first dustproof film 26 and a second dustproof film 28 covering opposite sides of the positioning frame 22.

The positioning frame 22 is made of a hard material such as PC, and has a thin plate-like structure as a whole. In the illustrated embodiment, the positioning frame 22 is a square thin plate and includes a first side and a second side opposite to each other, wherein the first side is a top side 220 and the second side is a bottom side 222. A stepped hole 224 is formed in the center of the positioning frame 22, and the stepped hole 224 penetrates the positioning frame 22 in the thickness direction. The stepped hole 224 includes a first positioning hole 226 and a second positioning hole 228 sequentially disposed and communicating with each other, wherein the size of the first positioning hole 226 is smaller than that of the second positioning hole 228, and an annular stepped surface 229 is formed between the first positioning hole 226 and the second positioning hole 228. In the illustrated orientation, the first positioning hole 226 is located above the second positioning hole 228, and the first positioning hole 226 penetrates through the top surface 220 of the positioning frame 22 for positioning and assembling the protective film 24; the second positioning hole 228 penetrates through the bottom surface 222 of the positioning frame 22 for positioning and assembling with the lens 10.

The shape and size of the first positioning hole 226 are the same as those of the protection film 24 in design, and both the first positioning hole 226 and the protection film 24 are racetrack-shaped in this embodiment. Since the size and shape of the first positioning hole 226 are consistent with the size and shape of the protection film 24, the protection film 24 is embedded in the first positioning hole 226, and a gapless fit is formed between the first positioning hole and the protection film 24, so that the protection film 24 cannot move relative to the positioning frame 22. It should be understood that even though the protection film 24 and the first positioning hole 226 are designed to be in a clearance-free fit, there may be tolerance in actual manufacturing, so that a small tolerance gap, such as a tolerance gap of 0-0.3 mm, may still be formed between the two in actual products, i.e. in actual products, the gap between the outer edge of the protection film 24 and the inner edge of the first positioning hole 226 is 0-0.3 mm, which does not affect the definition of the first positioning hole 226 on the position of the protection film 24, and ensures that the protection film 24 and the lens 10 are aligned when being attached. Preferably, the depth of the first positioning hole 226 is equal to or greater than the thickness of the protection film 24, and in this embodiment, the depth of the first positioning hole 226 is equal to the thickness of the protection film 24, so that the protection film 24 can contact with the outer surface 12 of the lens 10 when the film is attached.

The second positioning hole 228 has the same shape as the lens 10, and is also racetrack-shaped in this embodiment. The second positioning hole 228 has the same size as the largest size of the circumferential side 14 of the lens 10, so that the entire lens 10 can be nested in the second positioning hole 228, a gapless fit is formed between the two, and the positioning frame 22 cannot move relative to the lens 10. It should be understood that the gapless fit of the second positioning hole 228 and the circumferential side 14 of the lens 10 also means that the design size and shape are consistent, but there may be a slight tolerance gap between the lens 10 and the second positioning hole 228 due to the tolerance when the lens 10 is inserted into the second positioning hole, and the tolerance gap does not affect the alignment of the lens 10 and the positioning frame 20. Preferably, the depth of the second positioning hole 228 is greater than or equal to the height of the lens 10 protruding out of the mobile phone shell, so that the lens can be completely embedded into the second positioning hole 228 during film pasting, and the two form stable matching. In this embodiment, the depth of the second positioning hole 228 is the same as the height of the lens 10 protruding from the housing of the mobile phone.

The first dustproof film 26 is attached to the top surface 220 of the positioning frame 22 and seals the first positioning hole 226, and the second dustproof film 28 is attached to the bottom surface 222 of the positioning frame 22 and seals the second positioning hole 228. Due to the first and second dust-

proof films

26 and 28, dust and the like in the air cannot enter the stepped hole 224 of the positioning frame 22, and the cleanness of the protective film 24 is ensured. The first and second dust-

proof films

26, 28 may be made of soft plastic, such as PET, and are respectively and fixedly connected to the top surface 220 and the bottom surface 222 of the positioning frame 22 by electrostatic adsorption or adhesion, so that the dust-

proof films

26, 28 can be torn off from the positioning frame 22 by applying a slight force during film pasting.

The protective film 24 is preferably a tempered glass film, or may be a transparent film made of other materials and having a lens protection function. The protective film 24 is adhered to the first dust-proof film 26 and is accommodated in the first positioning hole 226. The shape and size of the protective film 24 are consistent with those of the outer surface 12 of the mobile phone lens 10, and the protective film can just shield the whole outer surface 12 of the lens 10 after being attached, so that the lens 10 is prevented from being scratched or worn. Preferably, both sides of the protective film 24 have adhesiveness. Initially, as shown in fig. 3, the upper surface of the protective film 24 is adhered to the inner side of the first dust-proof film 26 and flush with the top surface 220 of the positioning frame 22, and the lower surface is flush with the step surface 229 in the step hole 224. When attaching the film, as shown in fig. 6, the protective film 24 is adhered to the outer surface 12 of the lens 10 through the lower side thereof.

When the lens film assembly 20 of the present invention is used for film pasting, as shown in fig. 4, the second dust-proof film 28 on the bottom surface 222 of the positioning frame 22 is torn off to expose the second positioning hole 228. Then, as shown in fig. 5-6, the second positioning hole 228 of the lens film assembly 20 is aligned with the lens 10 and covers the lens 10, and the lens 10 and the positioning frame 22 form a gapless fit. Meanwhile, due to the play-free fit of the protective film 24 with the first positioning hole 228 of the positioning frame 22, the position of the protective film 24 is fixed and aligned with respect to the lens 10, particularly, the outer surface 12 of the lens 10. The outer surface 12 of the lens 10 is flush with the step surface 229 and just contacts the lower side of the protective film 24. At this time, the position of the first dust-proof film 26 corresponding to the protective film 24 is lightly pressed to adhere the protective film 24 to the outer surface 12 of the lens 10. Finally, as shown in fig. 7, the first dustproof film 26 is torn off and the positioning frame 22 is removed from the lens 10, thereby completing the film pasting. During the whole film pasting process, a user can hold the positioning frame 22 by hand and cannot pollute the protective film 24.

In the above embodiment, the depth of the first positioning hole 226 is equal to the thickness of the protection film 24, the depth of the second positioning hole 228 is equal to the height of the lens 10, and the total thickness of the positioning frame 22 is equal to the sum of the height of the lens 10 and the thickness of the protection film 24. When the positioning frame 22 is sleeved on the lens 10, the outer surface 12 of the lens 10 is just in contact with the protective film 24, and the position after pressing and pasting is accurate.

It should be understood that in some embodiments, the depth of the positioning holes 226 and 228 may also be different from the thickness of the protective film 24 or the height of the lens 10, for example, the depth of the first positioning hole 226 may be slightly shallower relative to the thickness of the protective film 24, the depth of the second positioning hole 228 may be slightly deeper relative to the height of the lens 10, and the protective film 24 partially extends into the second positioning hole 228 to be attached to the outer surface 12 of the lens 10, so as to form precise positioning, and ensure precise attachment of the protective film 24 to the outer surface 12 of the lens 10.

It should be understood that in some embodiments, when the positioning frame 22 is fitted over the lens 10, a space may be left between the outer surface 12 of the lens 10 and the protective film 24. For example, the depth of the first positioning hole 226 is greater than the thickness of the protection film 24, the lower side surface of the protection film 24 is higher than the step surface 229, and the outer surface 12 of the lens 10 is spaced from the protection film 24 when the lens extends into the second positioning hole 228. When the protective film is attached, the protective film 24 is pressed downwards to be attached to the outer surface 12 of the lens 10, so that accurate positioning can be achieved, and the protective film 24 is guaranteed to be attached to the outer surface 12 of the lens 10 accurately.

In addition, in the embodiment shown in fig. 6, the second positioning hole 228 is a column shape, and the size of the cross section thereof is not changed along the axial direction. In the embodiment shown in fig. 8, the second positioning hole 228 'is tapered, and the cross-sectional size thereof gradually decreases toward the first positioning hole 226 along the axial direction thereof, so as to fit with the tapered circumferential side surface 14' of the lens 10. When the positioning frame 22 is fitted over the lens 10, the second positioning hole 228 is fitted to the circumferential side 14' of the lens 10 without a gap.

It should be understood that, when the shape and size of the circumferential side surface of the lens are changed, the size and shape of the second positioning hole may be completely consistent with the circumferential side surface, or may be a columnar structure in the embodiment shown in fig. 6, as long as the size design of the second positioning hole meets the maximum size of the circumferential side surface, the positioning frame sleeve may be sleeved on the lens through the second positioning hole when the film is attached, at this time, although a gap is left between the second positioning hole of the positioning frame and the axial side surface of the lens at some positions, the position between the positioning frame and the lens can still be accurately positioned through the maximum size position of the axial side surface of the lens and the mobile phone shell, so that the position between the positioning frame and the lens is ensured to be fixed when the.

In a word, in the utility model discloses in, the locating frame 22 forms the first locating hole 226 with the surface 12 adaptation of protection film 24 or camera lens 10 and with the second locating hole 228 of the circumference side 14 adaptation of camera lens 10, and the fixed position of protection film 24 can not remove in locating frame 22, and fixed position can not remove when locating frame 22 overlaps on camera lens 10, and the relative surface 12 of camera lens 10 in the position of protection film 24 when the pad pasting is fixed and aimed at like this, behind the pad pasting the protection film 24 can perfectly cover and protect the surface 12 of camera lens 10, avoids scraping flower, wearing and tearing etc..
