[0029] Figure 1 A lens protective film in an embodiment of the utility model is shown, and the lens protective film comprises: a base 1, a first lens protective film 2, and a flexible member 3; a first opening is provided on the base 1, and the first lens protective film 2 is provided in the first opening and connected to the base 1 through the flexible member 3.

[0030] Among them, this embodiment can be applied to telescopic lenses, including telescopic lenses for mobile phones and telescopic lenses in cameras, etc. The shape of the base 1 is adapted to the lens module equipped with the telescopic lens, and can be made of plastic, glass or metal materials. The first opening opened on the base 1 corresponds to the telescopic lens, and the first lens protective film 2 is arranged in the first opening and connected to the base 1 through the flexible part 3, and the first opening is sealed by the first lens protective film 2 and the flexible part 3. Among them, adhesive is provided at the bottom of the connection between the flexible part 3, the first lens protective film 2 and the base 1. The first lens protective film 2 can be a flexible film or a tempered film, such as a flexible plastic film or a tempered glass film. The base 1 can be adapted to the lens module of electronic devices such as mobile phones to achieve a positioning effect, so that the first lens protective film 2 can be accurately attached to the telescopic lens. The edges of the flexible part 3 and the first lens protective film 2 and the edge of the first opening are connected with adhesive. The flexible part 3 is made of transparent rubber or other flexible materials. During the telescopic process of the telescopic lens, the telescopic amount of the telescopic lens can be compensated by the deformation of the flexible part 3 itself. While protecting the surface of the telescopic lens, it can also prevent dust, water droplets and other impurities from entering the gap of the telescopic lens, thereby improving the service life of the telescopic lens.

[0031] In one embodiment of the present invention, the flexible member 3 is located at the bottom of the first lens protection film 2 and the base 1. In this way, the connection between the flexible member 3, the first lens protection film 2 and the base 1 can be arranged inside the base 1, so that the lens protection film in the embodiment of the present invention is smoother in appearance, and the connection between the flexible member 3 and each component is not easily destroyed or damaged, thereby increasing the service life.

[0032] In one embodiment of the utility model, the lens protective film is applied to a lens module of an electronic device such as a mobile phone, the lens module includes a lens fixing seat and a telescopic lens, the telescopic lens is fixedly installed in the lens fixing seat, the base 1 covers the lens fixing seat, the first lens protective film 2 is used to protect the telescopic lens, and the flexible member 3 is deformed when the telescopic lens is extended or retracted to adapt to the extension and retraction of the telescopic lens.

[0033] Among them, in this embodiment, the utility model is applied to the lens module of the mobile phone, and the lens module may include a lens fixing seat and a telescopic lens, and the telescopic lens is installed in the lens fixing seat, and the shape of the base 1 is adapted to the lens fixing seat. For example, most of the lens modules on the back of existing mobile phones are protruded from the back of the mobile phone, and the bottom of the base 1 can be provided with a mounting groove according to the protruding height of the lens module, and the shape of the mounting groove is the same as that of the protruding lens module. In this embodiment, the bottom surface of the base 1 is an adhesive surface, and an adhesive is provided on the adhesive surface, and the base 1 is connected to the lens module through the adhesive.

[0034] In one embodiment of the present invention, the flexible member 3 is connected to the first lens protective film 2, the base 1 and the first lens protective film 2 by adhesive. The first lens protective film 2 can be a tempered film, which has higher protection performance than the flexible protective film and is easier to connect with the flexible member 3. By setting adhesive on the edge of the tempered film, the inner edge of the flexible member 3 can be connected to the edge of the tempered film, and the deformation of the flexible member 3 when the telescopic lens is extended and retracted is used to meet the movement of the first lens protective film 2 relative to the base, so that the lens protective film in the embodiment of the present invention can adapt to the extension and retraction of the telescopic lens.

[0035] In an embodiment of the present invention, the flexible member 3 includes at least one folded portion; the folded portion is used to compensate for the telescopic amount of the telescopic lens.

[0036] In this embodiment, the folded portion can be understood as a structure formed by the surface area of ​​the flexible member 3 being larger than the area between the first lens protective film 2 and the first opening, and the folded portion is evenly distributed on the flexible member 3. Figure 1 , Figure 4 The circles of protrusions surrounding the flexible member 3 can ensure that when the telescopic lens is telescopic, the expansion and contraction amounts of various parts of the flexible member 3 are the same, thereby ensuring the overall flatness of the lens protection film in the embodiment of the utility model.

[0037] In another embodiment of the present invention, the flexible member 3 may have multiple folds, such as 2, 3, 4 or even more folds. More folds mean that the flexible member 3 can adapt to the telescopic amount of different types of telescopic lenses. Figure 3 , Figure 4As shown, when the telescopic amount of the telescopic lens is compensated by the pleated portion, compared with the flexible member 3 with one pleated portion, under the same telescopic amount, providing multiple pleated portions can reduce the undulation height of a single pleated portion, so that the lens protective film in the embodiment of the utility model is smoother.

[0038] Furthermore, in another embodiment of the utility model, the pleated portion provided on the flexible part 3 corresponds to the telescopic amount of the telescopic lens, that is, the deformation margin provided by the pleated portion for the flexible part 3 is the same as the telescopic amount of the telescopic lens. This situation can be specially customized for a certain lens module. The effect is that during the deformation of the flexible part 3, the pleated portions will not be squeezed or folded.

[0039] In one embodiment of the utility model, the flexible member 3 is an annular rubber ring with elastic deformation, the inner ring edge of the annular rubber ring is connected to the edge of the first lens protective film 2, and the outer ring edge of the annular rubber ring is connected to the edge of the first opening, so that the annular rubber ring and the first lens protective film 2 seal the first opening.

[0040] In this embodiment, the flexible member 3 is an annular rubber ring structure, and transparent rubber is used as the material of the annular rubber ring. By utilizing its good corrosion resistance, sealing, elasticity and deformation ability, the lens protection film of the utility model can achieve the most ideal effect. The annular rubber ring is a complete circular ring-shaped sheet structure, and the thickness can be the same as the first lens protection film 2. The lower thickness can facilitate the deformation of the annular rubber ring and has a higher flatness.

[0041] In one embodiment of the utility model, a first fixing ring 4 and / or a second fixing ring 5 is provided at the bottom of the flexible member 3; wherein the first fixing ring 4 is located at the connection between the flexible member 3 and the first lens protective film 2; and the second fixing ring 5 is located at the connection between the flexible member 3 and the first opening.

[0042] Among them, the first fixing ring 4 and the second fixing ring 5 are provided with adhesive at the bottom, which is used to be fixedly connected with the corresponding position of the lens module. The first fixing ring 4 and the second fixing ring 5 can be made of hard materials, such as plastic, metal, etc. In this embodiment, the first fixing ring 4 and the second fixing ring 5 are both made of hard heat-insulating materials, such as extruded polystyrene board (XPS) and foamed polystyrene board (EPS), both of which have good heat-insulating properties and are light and easy to process. When the first lens protective film 2 is made of flexible material, by arranging the hard first fixing ring 4 at the bottom of the flexible part 3, the flatness of the first lens protective film 2 can be maintained, so as to facilitate the first lens protective film 2 to be attached to the telescopic lens; at the same time, the mobile phone lens module is usually arranged near the heat source such as the CPU. When the mobile phone is running at high load, the temperature of the lens module is relatively high. Through the heat insulation effect of the first fixing ring 4 and the second fixing ring 5, the connection stability between the flexible part 3 and the first lens protective film 2 and the first opening can be ensured. Furthermore, when the flexible member 3 is made of a material with a weak heat dissipation capability such as rubber, the first fixing ring 4 and the second fixing ring 5 can also prevent the flexible member 3 from undergoing thermal deformation itself.

[0043] like Figure 1 and Figure 2 As shown, in one embodiment of the utility model, a second opening is further provided on the base 1 , the size of the second opening is smaller than the size of the first opening and is spaced apart from the first opening, and the second opening is provided with a second lens protective film 9 .

[0044] The small lens can be an integrated lens module integrated with the telescopic lens, or a Figure 1 and Figure 2 As shown, the small lenses are dispersed on both sides of the telescopic lens, so the lens protection mold in the embodiment of the utility model also includes two second lens protection films 9, which are arranged on the second openings on the base 1 corresponding to the small lenses in the telescopic lens module, and are circular or straight groove-shaped. Through the second openings, the small lenses are fixed to the small lenses, so that the first lens protection film 2 can be pasted on the telescopic lens to play a positioning effect, and play a protective role for the small lenses. In addition, if the small lens also has a telescopic function, a flexible member 3 can be set on the second opening, and the connection method between the flexible member 3 and the second lens protection film 9 is the same as that of the first lens protection film 2, which will not be repeated here.

[0045] In an embodiment of the utility model, a third opening is further provided on the base 1, and the third opening may also be circular or straight-mouthed. The first opening, the second opening and the third opening are arranged in a triangle.

[0046] The third opening may also be provided with a second lens protection film 9 to adapt to the lens requirements of the lens module, and the arrangement shapes of the first opening, the second opening, and the third opening may be adjusted according to actual conditions. In this embodiment, the telescopic lens and the other two lenses are distributed in a triangular shape.

[0047] Furthermore, in an embodiment of the utility model, a first boss 7 is provided on the base 1, the first opening is located on the first boss 7, the first lens protective film 2 is provided in the first opening and is connected to the first boss 7 through the flexible member 3; a second boss 8 is provided on the base 1, the second opening is provided on the second boss 8, and the height of the second boss 8 is lower than the height of the first boss 7.

[0048] Among them, this embodiment is applied to the telescopic lens module of a mobile phone, the height of the first boss 7 and the second boss 8 is equivalent to the height of the telescopic lens module protruding from the back of the mobile phone, and the first boss 7 and the second boss 8 respectively correspond to each lens on the telescopic lens module, thereby increasing the convenience of installation.

[0049] In an embodiment of the present invention, the first boss 7 is connected to at least one of the second bosses 8 .

[0050] When the distance between the first opening and the second opening is relatively close, the wall thickness between the two is relatively low and is easily damaged. Therefore, the first boss 7 and the second boss 8 can be connected to each other to increase the structural strength between the first opening and the second opening and improve the service life.

[0051] Alternatively, when the small lens and the telescopic lens in the lens module are connected to each other, the first boss 7 and the second boss 8 may also be connected to increase the fit and ensure installation accuracy.

[0052] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment of the present invention, a release film 6 is further provided at the bottom of the lens protection film for isolating the adhesive surface of the first lens protection film 2 and the adhesive surface of the second lens protection film 9 from the external environment.

[0053] The shape of the release film 6 is the same as that of the bottom of the base 1. When the user uses it, first peel off the release film 6 from the base 1, and then install the base 1 on the corresponding lens module. The bottom surface of the base 1 is provided with adhesive, which is connected to the lens fixing seat in the lens module through the adhesive.
