Figure 6 This is the second schematic diagram of the disassembled structure of the lens protection device, the mobile terminal protection shell and the mobile terminal in the first embodiment of the utility model.

[0032] like Figures 1 to 6As shown, a lens protection device 10 is provided in the first embodiment of the utility model. The lens protection device 10 is provided with a lens groove 101 matching the lens module 31, so that the lens protection device 10 can cooperate with the lens module 31. The lens protection device 10 includes a lens film frame 11 and a protective film 12 connected to the lens film frame 11. The lens film frame 11 is provided with an opening 102. The protective film 12 is located at the opening 102 and corresponds to at least the telescopic lens 311 of the lens module 31. The protective film 12 is movably connected to the lens film frame 11. For example, the protective film 12 can move relative to the lens film frame 11 in the axial direction of the opening 102. Among them, the axial direction of the opening 102 is parallel to the telescopic direction of the telescopic lens 311. The lens film frame 11 can be made of a rigid material, such as metal or plastic, so that it can play a good protective role on the frame of the lens module 31 and prevent the frame of the lens module 31 from being scratched during use. The protection film 12 is a transparent film made of a material with high transparency to avoid interference with the imaging of the lens module 31 .

[0033] The utility model arranges the protective film 12 to be movable relative to the lens film frame 11 in the axial direction of the opening 102, and the protective film 12 at least corresponds to the telescopic lens 311 of the lens module 31, so that when the telescopic lens 311 is telescoped, the protective film 12 can be telescoped synchronously with the telescopic lens 311, thereby solving the problem that the existing lens film cannot be telescoped synchronously with the lens.

[0034] In this embodiment, the protective film 12 is an elastic protective film, and the edge of the elastic protective film is fixedly connected to the lens film frame 11, and the edge of the elastic protective film is tightly fitted to the lens film frame 11 to achieve a waterproof design. When the telescopic lens 311 is telescoped, the protective film 12 will undergo elastic deformation, thereby moving synchronously with the telescopic lens 311 in the axial direction of the opening 102. Among them, the elastic protective film is made of a material with high transparency and high elasticity, which can be telescoped synchronously with the telescopic lens 311 while avoiding interference with the imaging of the lens module 31. Of course, in another embodiment, the protective film 12 can also be a rigid protective film, and the edge of the rigid protective film is slidably connected to the lens film frame 11. For example, a slide groove is provided on the inner wall of the opening 102, and the edge of the rigid protective film is arranged in the slide groove, so that the rigid protective film can slide in the opening 102. Alternatively, the edge of the elastic protective film can also be arranged to be slidably connected to the lens film frame 11.

[0035] In this embodiment, the opening 102 includes a first opening 102a and a second opening 102b, the first opening 102a and the second opening 102b are spaced apart from each other, the first opening 102a corresponds to the telescopic lens 311, the protective film 12 is located at the first opening 102a and corresponds to the telescopic lens 311, and the second opening 102b corresponds to the fixed lens 312 of the lens module 31. That is, in this embodiment, the protective film 12 only corresponds to the telescopic lens 311, and does not cover the fixed lens 312 of the lens module 31.

[0036] Furthermore, the lens film frame 11 is detachably connected to the lens module 31, so that it is easy to replace the lens protection device 10. In this embodiment, the inner wall of the lens groove 101 of the lens film frame 11 is interference-fitted with the outer wall of the lens module 31, so that the lens protection device 10 is installed on the lens module 31. Of course, in other embodiments, the lens film frame 11 can also be made of ferromagnetic material, so that the lens protection device 10 can be magnetically matched with the lens module 31 of the metal frame.

[0037] like Figure 3-4 As shown, this embodiment also provides a mobile terminal protective shell 20, including the lens protection device 10 as described above. The mobile terminal protective shell 20 is provided with a receiving slot 201 for loading a mobile terminal 30 (such as a mobile phone, a tablet computer or a handheld computer), so as to facilitate the installation of the mobile terminal protective shell 20 on the mobile terminal 30. Among them, the mobile terminal 30 has a lens module 31, which protrudes from the back of the mobile terminal 30, and the lens module 31 has multiple lenses, such as a telescopic lens 31 and a fixed lens 312.

[0038] In this embodiment, the lens protection device 10 and the mobile terminal protection shell 20 are split structures, that is, the lens protection device 10 and the mobile terminal protection shell 20 are two parts that are not connected. Among them, the mobile terminal protection shell 20 is provided with an avoidance hole 202 for avoiding the lens protection device 10, so that the lens protection device 10 can be exposed from the avoidance hole 202. Of course, in other embodiments, the lens protection device 10 is connected to the mobile terminal protection shell 20, for example, the lens protection device 10 and the mobile terminal protection shell 20 can be integrally formed by a casing process (also called an injection molding process or a rubber encapsulation process), or bonded together by glue.

[0040] Figure 7 It is a three-dimensional structural schematic diagram of the lens protection device in the second embodiment of the utility model. Figure 8 It is a schematic diagram of the disassembled structure of the lens protection device in the second embodiment of the present utility model. Fig. 9This is a schematic diagram of the cross-sectional structure of the lens protection device in the second embodiment of the present utility model when it is matched with the mobile terminal. Fig. 9 As shown, the lens protection device provided by the second embodiment of the present invention is different from the lens protection device provided by the first embodiment ( Figures 1 to 6 ) are substantially the same, except that, in this embodiment:

[0041] The sizes of the opening 102 and the protective film 12 are both corresponding to the entire lens module 31, that is, the number of the opening 102 and the protective film 12 is one and can cover the entire lens module 31, and the protective film 12 covers not only the telescopic lens 311 but also the fixed lens 312. Among them, the protective film 12 has a larger area and is more likely to undergo elastic deformation, so as to reduce the impact on the telescopic lens 311 when performing a telescopic action.

[0042] It should be understood by those skilled in the art that the rest of the structure and working principle of this embodiment are the same as those of the first embodiment and will not be described in detail here.

Fig.10 As shown, the lens protection device provided in the third embodiment of the present invention is different from that in the first embodiment ( Figures 1 to 6 )、Example 2 ( Figures 7 to 9 ) are substantially the same, except that, in this embodiment:

[0045] The protective film 12 includes a rigid portion 121 located at the center of the protective film 12 and an elastic portion 122 located at the edge of the protective film 12, the edge of the rigid portion 121 is fixedly connected to the elastic portion 122, and the edge of the elastic portion 122 is fixedly connected to the lens film frame 11. When the telescopic lens 311 is telescoped, the elastic portion 122 will undergo elastic deformation, so that the rigid portion 121 and the telescopic lens 311 move synchronously in the axial direction of the opening 102. Among them, the rigid portion 121 can better protect the lens and prevent the lens from being scratched. Of course, the edge of the elastic portion 122 can also be slidably connected to the lens film frame 11, so that the protective film 12 can be synchronously telescoped with the telescopic lens 311.

[0046] It should be understood by those skilled in the art that the rest of the structure and working principle of this embodiment are the same as those of Embodiment 1 and Embodiment 2, and will not be described in detail here.
