[0067] Sixthly, in the application, the filter module is composed of a filter frame and a lens, and can be detachably arranged outside the lens module of the mobile terminal. The lens of the mobile terminal can be used to take pictures by adding a filter, and an image different from the original imaging visual effect can be obtained.

[0068] Seventhly, in the application, the structural stability and disassembly convenience of the modular combined mobile terminal protective shell are improved through the innovation of the module split mode and the connection node design of any two or more modules in the frame, backboard, filter module, lens protection frame, key module and switch buckle structure of the mobile terminal protective shell. Each module contains multiple styles for selection, which provides users with more customization space and higher personalized customization effect. On the basis of meeting the conventional mobile terminal protection needs, users can freely select and match modular components according to personal preferences, replace the corresponding module style according to the specific use scene, and meet the needs of multiple scenes through the integration of modules, which is conducive to better increasing the functional diversity and style richness of the mobile terminal protective shell.

[0069] Eight, in the application, the modular design of each part is adopted and the disassembly and assembly are facilitated, which is beneficial to the development of circular economy and green sustainable development of society. When local loss occurs during product use, only the damaged module needs to be replaced, thereby prolonging the use cycle of the product. In addition, the used module components can be classified and recycled according to the materials, and processed as raw materials for secondary production, so as to achieve more refined recycling of materials, reduce environmental pollution and resource consumption.

[0086] Embodiment one

[0087] The present embodiment provides a mobile terminal protective case, which can be a mobile phone protective case, a tablet computer protective case, or a notebook computer protective case, etc. Of course, the mobile terminal protective case can also be any other protective case of a mobile terminal, and the embodiments of the present application do not limit this.

[0088] As Figure 1 ,Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In one embodiment, a housing of a mobile terminal, such as a mobile phone protective case, is provided, and only this case is described as an example. The mobile phone protective case comprises a frame 1 having a receiving space for accommodating a mobile terminal, a back plate 2, and a switch buckle structure 6. The back side of the frame 1 is provided with an inner concave back plate mounting groove 11. The back plate 2 is mounted in the back plate mounting groove 11. One side of the back plate mounting groove 11, such as the lower side, is provided with a switch buckle mounting groove 12. The switch buckle structure 6 is movably connected in the switch buckle mounting groove 12. When the switch buckle structure 6 is in the locking position, the back plate 2 is locked in the back plate mounting groove 11. When the switch buckle structure 6 is in the release position, the locking is released, and the back plate 2 can be removed from the back plate mounting groove 11. In this embodiment, the movable connection is preferably a rotating connection. It should be noted that in some embodiments, the switch buckle mounting groove 12 is not limited to being provided on the lower side, such as the side or inner side, of the back plate mounting groove 11.

[0089] From the above, when the back plate 2 needs to be mounted, the user can first open the switch buckle structure 6 from the locking position at the bottom of the frame 1 to the release position, then place the back plate 2 in the back plate mounting groove 11, and then close the switch buckle structure 6 from the release position to the locking position to lock the back plate 2 in the back plate mounting groove 11. This completes the installation of the back plate 2. After installation, the structure of the combined modules of the frame 1 and the back plate 2 is stable, and does not fall off, move, deform, etc. The entire process is convenient and fast, and does not require the mobile terminal to be removed from the frame, nor does it affect the normal use of the remaining modules.

[0090] In addition, it is worth mentioning that the back plate mounting groove 11 in this embodiment is preferably an inner concave slot with a locking edge.

[0091] Further preferably, in this embodiment, when the switch buckle structure 6 is in the locking position, the circumference thereof is aligned with the bottom edge of the frame 1 to ensure that it is integrated with the frame 1, has good flatness, and has a good visual effect. It should be noted that in this embodiment, when the switch buckle structure 6 is in the locking position, the circumference thereof can also be flush with the bottom edge of the frame 1 to facilitate the user to freely select and match different structures, colors, materials, and surface texture configurations of the modules according to their own preferences.

[0092] In addition, in the present embodiment, the frame body of the frame 1 is further provided with a mounting frame body 16, and the housing of the mobile terminal further comprises a lens protection frame 4 arranged on the mounting frame body 16, an inner side of the mounting frame body 16 is provided with a lens protection frame positioning clamping groove 15, a circumference of the lens protection frame 4 is provided with a frame body connecting part 41, and the frame body connecting part 41 is detachably mounted on the lens protection frame positioning clamping groove 15, so as to realize the modular installation of the lens protection frame 4 on the frame 1. It should be noted that in some embodiments, the lens protection frame 4 can also be integrally formed with the mounting frame body 16, that is, a part of the mounting frame body 16, and no specific limitation and elaboration is made here.

[0093] In addition, it is worth mentioning that in the present embodiment, the lens protection frame 4 can be provided with a filter module 3, and the filter module 3 in the present embodiment is preferably detachably mounted on the lens protection frame 4. In addition, it should be noted that the filter module 3 in the present embodiment can be integrally formed with the lens protection frame 4, and no specific limitation and elaboration is made here.

[0094] Further preferably, in the present embodiment, the two sides of the frame 1 are detachably mounted with a key module 5. In addition, the two sides of the frame 1 are provided with a key connecting port 14, and the key connecting port 14 is provided with a key positioning clamping groove 141, so that the key module 5 can be detachably mounted in the key positioning clamping groove 141. In the present embodiment, each key can accurately match the position of the mobile phone button, and the relative position of the key module 5 on the frame 1 is determined by the key positioning clamping groove 141 of the frame 1. As shown in Figure 4 and Figure 9As shown, when the key module 5 is installed, the key module 5 can be aligned with the key positioning clamping groove 141 from the inside of the frame 1, and the key module 5 is extruded outward, so that the key clamping groove 51 is buckled into the key positioning clamping groove 141. Since the bottom profile size of the key clamping groove 51 is relatively larger than the key positioning clamping groove 141, after the mobile phone is installed, it can be ensured that the key module 5 will not fall out from the outside. The design width of the key clamping groove 51 is greater than the thickness of the key positioning clamping groove 141, which is beneficial to reserve a small amount of movement distance in the stress direction of the key module 5. When the surface of the key module 5 is subjected to external pressure, the pressure can be transmitted to the mobile phone button through the bottom surface of the key module 5, so as to achieve the effect of pressing the mobile phone button. When the external pressure is removed, the bottom of the key module 5 is subjected to the thrust of the mobile phone button rebound, and the key module 5 is pushed back to the initial position. The profile size of the key positioning clamping groove 141 is slightly larger than the inner recess of the key clamping groove 51, and there is also a small amount of space reserved between the key module 5 and the key positioning clamping groove 141, which can reduce the resistance suffered by the key module 5 during movement, so that the pressing experience is smoother. When it is necessary to remove the key module 5, the mobile phone is first removed from the inside of the frame 1, and then the key module 5 is extruded inward from the outside of the frame 1, so that the key clamping groove 51 is separated from the key positioning clamping groove 141. Users can replace the style of the key module 5 according to needs, including different colors, materials, surface treatment methods, etc. Different styles of each independent key can be selected and replaced and combined flexibly. The number and specifications of the keys are not limited in the present application, as long as the scheme can be implemented. In addition, it should be noted that the key module 5 in the present embodiment can also be integrally formed with the frame 1.

The installation method in the present embodiment is preferably designed as "drawer type". When installation is required, the switch buckle structure 6 is first opened, then the back plate connecting structure 21 of the back plate 2 is aligned with the back plate mounting groove 11, and the back plate 2 is pushed to slide into the back of the frame 1. After the back plate 2 slides to the set position, the switch buckle structure 6 is closed, and the installation is completed. After installation, the stability of the back plate 2 can be ensured, and problems such as falling off, moving or deforming will not occur. Moreover, the entire process does not require the mobile phone to be removed from the frame, and does not affect the normal use of the remaining modules.
