[0033] like Figure 1 As shown, the embodiment of the present invention provides a protective shell 100, including a shell 10 and a functional part 20. Figure 2 The housing 10 has a device accommodating chamber 12 and a first key through hole 11 communicating with the device accommodating chamber 12. The functional component 20 is detachably mounted in the first key through hole 11. The functional component 20 is provided with a second key through hole 21 communicating with the device accommodating chamber 12.

[0034] In some embodiments, the function part 20 is further provided with a key connection portion 23 (see Figures 3 to 6 ).

[0035] The device accommodating cavity 12 is used to accommodate the electronic device that needs to be protected by the protective shell 100. In other words, when the protective shell 100 is set on the electronic device, the electronic device is located in the device accommodating cavity 12. The housing 10 includes, for example, a back plate and a side frame, and the back plate and the side frame together enclose the device accommodating cavity 12. The first button through hole 11 is opened corresponding to the position of the device button on the electronic device, for example, it is opened on the side frame of the housing 10, and the size of the first button through hole 11 is larger than the size of the device button. The size of the second button through hole 21 can be slightly larger than the size of the device button. When the functional part 20 is installed in the first button through hole 11, the second button through hole 21 can expose the device button, and the user can contact the device button through the second button through hole 21. Alternatively, the button structure 30 can be installed in the second button through hole 21, and the device button can be operated through the button structure 30. Specifically, the button connecting portion 23 provided on the functional part 20 is used to connect the button structure 30 so that the button structure 30 can be stably installed in the second button through hole 21. The functional component 20 can be made of the same material as or different from that of the housing 10 , and the functional component 20 can be made of a different color from that of the housing 10 .

[0036] For example, when the protective shell 100 is mounted on the electronic device, the device buttons on the electronic device can be operated in the following ways: (1) The functional part 20 is installed in the first button through hole 11, and the user can directly contact the device button through the second button through hole 21 to operate the device button. The functional part 20 can decorate the first button through hole 11 and guide the user to operate the device button. (2) In some scenarios, if a larger operating space is required to operate the device button, the functional part 20 can be removed from the first button through hole 11, and the device button can be directly operated through the first button through hole 11, making the operation more convenient. (3) In some scenarios, if the device button needs to be protected to prevent it from being exposed outside the protective shell, the button structure 30 can be installed in the second button through hole 21, and the button structure 30 can be used to operate different areas of the device button, fingerprint function, touch function, etc. Therefore, by setting the functional part 20 in this embodiment, the protective shell 100 can realize different usage methods according to different functions or requirements of the device button, which is more flexible and convenient.

[0037] The functional part 20 can be detachably installed in the first key through hole 11 by means of magnetism, adhesion, clamping, etc. In some embodiments, a first clamping portion 111 is provided on the side wall of the first key through hole 11, and a second clamping portion 24 is provided on the side of the functional part 20 facing away from the second key through hole 21, and the first clamping portion 111 and the second clamping portion 24 are clamped with each other. Figure 3 In one embodiment, Figure 1 The cross-sectional view at the section line L1 is viewed in the direction toward the back plate of the housing 10 (towards Figure 1 ), Figure 3 The upper side wall of the middle shell 10 is the side wall of the side frame facing the device accommodating cavity 12, and the lower side wall is the side wall of the side frame facing away from the device accommodating cavity 12. Figure 3 and Figure 4 In some embodiments, the first clamping portion 111 is a protruding structure, and the second clamping portion 24 is a groove structure. The first clamping portion 111 can be, for example, a protruding structure arranged around the entire circumference of the first button through hole 11, and the corresponding second clamping portion 24 can be a groove structure arranged around the entire circumference of the first button through hole 11. Of course, the first clamping portion 111 can also partially protrude on the side wall of the first button through hole 11, and the second clamping portion 24 can be arranged only in a partial area corresponding to the protruding structure. Or vice versa, the first clamping portion 111 can also be set as a groove structure, and the second clamping portion 24 can be set as a protruding structure. This embodiment is not limited to this.

[0038] In other embodiments, Figure 5 is a cross-sectional view corresponding to the section line L1 in one embodiment, and the viewing direction is toward the back plate of the housing 10 (towards Figure 1 ), Figure 5 The upper side wall of the middle shell 10 is the side wall of the side frame facing the device accommodating cavity 12, and the lower side wall is the side wall of the side frame facing away from the device accommodating cavity 12. Figure 5 and Figure 6 , a step surface 112 facing the device accommodating cavity 12 is provided on the side wall of the first button through hole 11. The functional part 20 includes a main body 22 and a flange portion 25 protruding from the main body 22. The functional part 20 is installed in the first button through hole 11 by snapping the flange portion 25 with the step surface 112. The step surface 112 can be arranged around the entire circumference of the first button through hole 11, and the corresponding flange portion 25 can be arranged around the entire circumference of the first button through hole 11. Or the flange portion 25 can be arranged only around a partial area of ​​the first button through hole 11. When installing the functional part 20, the functional part 20 can be loaded into the first button through hole 11 from the side of the device accommodating cavity 12, that is, installed from the inside to the outside, so that the flange portion 25 abuts against the step surface 112. The protective shell 100 is then put on the electronic device, and the side of the functional part 20 close to the device accommodating cavity 12 is blocked by the outer shell of the electronic device. The flange part 25 is clamped by the electronic device and the step surface 112, which can ensure that the functional part 20 is stably installed in the first button through hole 11 and is easy to install.

[0039] In some embodiments, the functional part 20 has an operation guide 26, which is located on the side of the functional part 20 away from the device accommodating cavity 12, and the operation guide 26 is used to guide the user to operate. For example, the operation guide 26 can be an area on the functional part 20 that is provided with a color or other identification that is different from the shell 10. By setting the operation guide 26, the user can quickly determine the location of the button to operate. Or in some embodiments, the second button through hole 21 is connected to the device accommodating cavity 12, the second button through hole 21 has a guide area, and the operation guide 26 encloses to form the guide area, refer to Figure 7 ( Figure 7 is a cross-sectional view corresponding to the section line L1 in one embodiment, and the viewing direction is toward the back plate of the housing 10 (towards Figure 1 ), Figure 7 The upper side wall of the middle shell 10 is the side wall of the side frame facing the device accommodating cavity 12, and the lower side wall is the side wall of the side frame facing away from the device accommodating cavity 12) and Figure 8 The aperture of the guide area gradually increases in the direction away from the device accommodating cavity 12. Figure 7 and Figure 8 The aperture of the middle guide area close to the device accommodating cavity 12 is D1, and the aperture of the end away from the device accommodating cavity 12 is D2, and D1 is smaller than D2. That is, by setting the corresponding side wall on the functional part 20 as an inclined side wall, the second key through hole 21 includes a portion with a gradually changing aperture. The inclined side wall is the operation guide part 26, and the portion with a gradually changing aperture is the operation guide area. The design of the second key through hole 21 with a larger aperture outside and a smaller aperture inside can achieve guidance of user operation, and provide a better user experience.

[0040] In some embodiments, reference Fig. 9 and Fig.10 The protective shell 100 also includes a key structure 30, which is detachably mounted in the second key through hole 21. When the key structure 30 is mounted in the second key through hole 21, the key structure 30 can be used to adapt the device keys, such as operating different areas, fingerprint functions, touch functions, and other different functions. For example, the key structure 30 has a structure that can realize the operation of different areas of the device keys, or the key structure 30 is a conductive key or the key structure 30 has multiple functions such as operating different areas and sensing conductivity. For example, key structures 30 with different functions can also be replaced to achieve different operations.

[0041] In some embodiments, the key structure 30 includes a conductive medium, which can be embedded in the key structure 30 or disposed on the surface of the key structure 30. The conductive medium is used to electrically connect objects that contact the inner and outer surfaces of the key structure 30 respectively. For example, when the key structure 30 is installed in the second key through hole 21, the surface of the key structure 30 facing the device accommodating cavity 12 is the inner surface, and the surface facing away from the device accommodating cavity 12 is the outer surface. The conductive medium can be configured in a columnar, granular, etc. shape and embedded in the key structure 30, and the opposite ends of the conductive medium are exposed from the inner and outer surfaces of the key structure 30 respectively. When the user's finger touches the outer surface of the key structure 30, it also touches one end of the conductive medium exposed to the outer surface of the key structure 30. The end of the conductive medium exposed to the inner surface of the key structure 30 contacts the device key, so the conductive medium can electrically connect the user's finger to the device key. Or the conductive medium, for example, includes conductive coatings respectively coated on the inner and outer surfaces of the key structure 30, and also includes conductive connectors respectively connecting the conductive coatings on the inner and outer surfaces of the key structure 30, so that when the user's finger touches the conductive coating on the outer surface of the key structure 30, and the conductive coating on the inner surface of the key structure 30 contacts the device key, the conductive connector connects the conductive coating on the inner surface of the key structure 30 and the conductive coating on the inner surface, thereby realizing the electrical connection between the finger and the device key, thereby realizing functions such as fingerprint and touch sensing.

[0042] In some embodiments, the button connecting portion 23 is located on the inner wall of the second button through hole 21 . Fig.11 In one embodiment, Fig. 9 The cross-sectional view at the middle section line L2 is viewed in the direction toward the back plate of the housing 10 (towards Fig. 9 ), Fig.11 The upper side wall of the middle shell 10 is the side wall of the side frame facing the device accommodating cavity 12, and the lower side wall is the side wall of the side frame facing away from the device accommodating cavity 12. Fig.11 , the key connection part 23 is a protrusion structure, and the key structure 30 is provided with a slot 31 matching the key connection part 23. The key structure 30 is installed in the second key through hole 21 by engaging with the key connection part 23 through the slot 31. In some embodiments, the key connection part 23 is a groove structure, and the key structure 30 is provided with a protrusion matching the key connection part 23. The key structure 30 is installed in the second key through hole by engaging the protrusion with the key connection part 23. Of course, the key structure 30 can also be installed in the second key through hole 21 by other methods such as magnetic attraction and pasting, and the present embodiment is not limited thereto. The structure of the key structure 30 installed in the second key through hole 21 can be designed with reference to the structure of the functional part 20 installed in the first key through hole 11.
