Description

Technical Field

[0001] This application relates to the field of electronic device accessories technology, and in particular to a protective case. Background Technology

[0002] Electronic devices such as mobile phones, tablets, and laptops are typically protected by protective cases. Some cases employ a full-coverage structure, including not only the outer shell but also a cover that can cover, for example, the screen of the electronic device. The cover, combined with the shell, provides comprehensive protection for the device. However, in some cases, the shell and cover are fixedly connected, and in certain environments, the cover may interfere with the normal operation of the electronic device. Utility Model Content

[0003] To address the aforementioned technical problems, this application proposes a protective case to improve its protective capability for electronic devices and its reliability.

[0004] This application provides a protective shell, comprising: a housing forming an open receiving cavity for accommodating an electronic device; a cover for opening and closing the opening, the cover being detachably connected to the housing; a first connecting assembly including a first connector and a third connector, the first connector being mounted on the housing and the third connector being mounted on the cover, the first connector and the third connector being detachably connected to each other; the first connector and the third connector being connected by a non-magnetic attraction; a second connecting assembly including a second connector and a fourth connector, the second connector being mounted on the housing and the fourth connector being mounted on the cover; the second connector and the fourth connector being detachably connected to each other; the second connector and the fourth connector being connected by a magnetic attraction; the detachable connection between the cover and the housing is achieved through the detachable configuration of the first connector and the third connector, and the detachable configuration of the second connector and the fourth connector.

[0005] The beneficial effects of the technical solution of this application are that the protective shell of this application includes a shell forming a receiving cavity and a cover for opening and closing the receiving cavity. By combining the shell and the cover, the protective shell can improve the protective capability of the electronic device. Moreover, the shell and the cover are detachably connected by two different detachable connection methods, namely magnetic attraction and non-magnetic attraction. This not only enables the detachable connection between the shell and the cover, but also improves the structural stability of the shell and the cover in the connected state, thereby improving the reliability of the protective shell.

In the embodiments of this application, a tablet is used as an example of an electronic device, and the protective case is described using a tablet's protective case as an example.

[0027] In some embodiments, such as Figures 1 to 8 As shown, the protective shell 10 includes: a first connecting assembly 11, a second connecting assembly 12, a housing 20, and a cover 30; the first connecting assembly 11 includes a first connector 210 and a third connector 310, and the second connecting assembly 12 includes a second connector 220 and a fourth connector 320; the housing 20 forms a receiving cavity A with an opening (not shown), which is used to receive electronic equipment (not shown); and the first connector 210 and the second connector 220 are mounted on the housing 20; the cover 30 is used to open and close the opening, and the third connector 310 and the fourth connector 320 are also mounted on the cover 20. Component 320 is installed on cover 30; first connector 210 and third connector 310 are detachably connected to each other; first connector 210 and third connector 310 are connected by non-magnetic attraction; second connector 220 and fourth connector 320 are detachably connected to each other; second connector 220 and fourth connector 320 are connected by magnetic attraction; the detachable connection between housing 20 and cover 30 is achieved by the detachable configuration of first connector 210 and third connector 310 and the detachable configuration of second connector 220 and fourth connector 320.

[0028] Detachable connection refers to a connection method in which two or more components are joined in a specific way and can be easily separated and reassembled without damaging the connectors or the components themselves. Detachable connection can balance structural stability and disassembly flexibility. In this embodiment, the shell 20 and the cover 30 are detachably connected, which can balance the stability of the assembly structure of the shell 20 and the cover 30, and also improve the flexibility of disassembly, so that the user can choose to install the cover 30 or not install the cover 30 to meet their requirements for the protective performance or feel of the protective shell 10.

[0029] In some embodiments, the detachable connection between the first connector 210 and the third connector 310 can be achieved by structural connectors such as snaps and slots, pins and keys, bolts and nuts, or by adhesive or Velcro.

[0030] In this embodiment, the protective shell 10 includes a shell 20 having a receiving cavity A and a cover 30 for opening and closing the receiving cavity A. The combination of the shell 20 and the cover 30 enhances the protective capability of the protective shell 10 for electronic devices. Furthermore, the shell 20 and the cover 30 are detachably connected through two different connection methods, which not only enables this detachable connection but also improves the structural stability of the shell 20 and the cover 30 in the connected state, thereby increasing the reliability of the protective shell 10. Additionally, the second connector 220 and the fourth connector 320 are connected magnetically, providing a magnetic feel during the assembly and disassembly of the shell 20 and the cover 30, improving the user experience.

[0031] In some embodiments, the second connector 220 includes a guide structure for limiting the relative position of the second connector 220 and the fourth connector 320 after they are connected. This increases the structural stability between the housing 20 and the cover 30.

[0032] In some embodiments, such as Figure 6 As shown, the first connector 210 includes a first snap-fit ​​portion 211, and the third connector 310 includes a second snap-fit ​​portion 311. When the cover 30 is assembled onto the housing 20, the first snap-fit ​​portion 211 and the second snap-fit ​​portion 311 snap into each other. The first snap-fit ​​portion 211 and the second snap-fit ​​portion 311 are detachably connected by snap-fit, making the installation and removal operation simple and the connection stable.

[0033] In some embodiments, such as Figure 6 As shown, the first snap-fit ​​portion 211 includes a mating groove 212, and the second snap-fit ​​portion 311 includes a connecting post 312. This embodiment achieves snap-fit ​​through a groove-post structure, which is simple and easy to implement, and can reduce the thickness of the structure in the snap-fit ​​state.

[0034] In some embodiments, the first snap-fit ​​portion 211 also includes a connecting post 312, and the second snap-fit ​​portion 311 includes a mating groove 212. Alternatively, other snap-fit ​​structures can be used to realize the first snap-fit ​​portion 211 and the second snap-fit ​​portion 311; or other connection structures can be used to realize the detachable connection between the first connector 210 and the third connector 310.

[0035] In some embodiments, such as Figure 6As shown, the connecting post 312 includes a first post segment 3121 and a second post segment 3122 arranged vertically. The second post segment 3122 extends from the end of the first post segment 3121 away from the housing 20 along the locking direction y. The mating groove 212 includes a mounting through hole 2121 and a mounting blind hole 2122. The mounting blind hole 2122 is arranged facing the interior of the housing 20. The mounting through hole 2121 and the mounting blind hole 2122 communicate along the locking direction y. The axial direction of the mounting through hole 2121 and the axial direction of the first post segment 3121 are perpendicular to the locking direction y. When the cover 30 is assembled on the housing 20, the first post segment 3121 is at least partially embedded in the mounting through hole 2121, and the second post segment 3122 is at least partially embedded in the mounting blind hole 2122.

[0036] One end of the first column segment 3121 is connected to the body of the cover 30, and the other end is connected to the second column segment 3122. The two segments can be integrally formed or integrally formed with the body of the cover 30. The mounting through hole 2121 of the mating groove 212 is used to insert the first column segment 3121, and the mounting blind hole 2122 is used to insert the second column segment 3122. The first column segment 3121 and the mounting through hole 2121 can limit the cover 30 and the housing 20 in the vertical plane of the locking direction y. Because the first column segment 3121 and the second column segment 3122 are perpendicular, the second column segment 3122 and the mounting blind hole 2122 can limit the cover 30 and the housing 20 in the locking direction y and its opposite direction. Therefore, this embodiment can achieve the limitation of the cover 30 and the housing 20 in three-dimensional space, thereby improving their connection stability. Furthermore, this structure facilitates the disassembly of the cover 30 and the housing 20.

[0037] During the assembly of the cover 30 to the housing 20, the connecting post 312 is first inserted into the mating groove 212 in the direction perpendicular to the locking direction y. Then, the connecting post 312 is moved toward the mounting blind hole 2122 in the locking direction y, so that the second post segment 3122 is embedded in the mounting blind hole 2122, thereby achieving the assembly of the cover 30 and the housing 20. Because the mounting blind hole 2122 faces the inside of the housing 20, the bottom wall of the mounting blind hole 2122 can prevent the second post segment 3122 from disengaging from the housing 20 in the direction perpendicular to the locking direction y.

[0038] During the process of disassembling the cover 30 from the housing 20, the connecting post 312 can first be moved away from the mounting blind hole 2122 in the opposite direction of the locking direction y, and then the connecting post 312 can be pulled out from the mating groove 212 in the opposite direction of the insertion direction, thereby realizing the disassembly of the cover 30 from the housing 20.

[0039] The first column segment 3121 and the second column segment 3122 are arranged in an L-shape, and the mounting cavity of the docking groove 212 is also arranged in an L-shape.

[0040] In some embodiments, such as Figures 5 to 8As shown, the second connector 220 includes a first magnetic 221, and the fourth connector 320 includes a second magnetic 321; when the cover 30 is assembled onto the housing 20, the first magnetic 221 and the second magnetic 321 are attracted together. This embodiment achieves a detachable connection between the cover 30 and the housing 20 through a magnetic structure, which simplifies the structure, reduces the difficulty of disassembly, increases the disassembly speed, and also improves the connection stability between the cover 30 and the housing 20.

[0041] In some embodiments, the first magnetic attractor 221 and the second magnetic attractor 321 can both be components capable of generating a magnetic field and attracting, such as permanent magnets or electromagnets. Alternatively, one of them can be a component capable of generating a magnetic field and attracting, such as permanent magnets or electromagnets, while the other can be a component that can be magnetized and attracted, such as iron.

[0042] In some embodiments, such as Figures 12 to 15 As shown, the second connector 220 includes multiple sets of first magnetic attractors 221, and the fourth connector 320 includes multiple sets of second magnetic attractors 321. When the cover 30 is assembled onto the housing 20, the first magnetic attractors 221 and the second magnetic attractors 321 are attracted together. The multiple sets of first magnetic attractors 221 and multiple sets of second magnetic attractors 321 can increase the magnetic attraction between the cover 30 and the housing 20, thereby increasing the connection stability and magnetic feel between the two.

[0043] In some embodiments, such as Figures 12 to 15 As shown, the fourth connector 320 includes a support portion 322 and multiple sets of second magnetic attractors 321 mounted on the support portion 322; the second connector 220 includes a mounting groove 21 and multiple sets of first magnetic attractors 221 disposed in the mounting groove 21; the mounting groove 21 is shaped relative to the support portion 322, and the support portion 322 can be embedded in the mounting groove 21; when the support portion 322 is embedded in the mounting groove 21, the first magnetic attractors 221 and the second magnetic attractors 321 are attracted to each other. In this way, the housing 20 can be used to limit the first magnetic attractors 221, thereby improving structural stability, and the overall thickness of the housing 20 with the first magnetic attractors 221 assembled can be reduced.

[0044] In some embodiments, the mating groove 212 is disposed in the mounting groove 21; the connecting post 312 is disposed in the support portion 322; when the support portion 322 is fitted into the mounting groove 21, the connecting post 312 is mated with the mating groove 212.

[0045] In some embodiments, the support portion 322 may be made of steel bars or sheets made of materials such as stainless steel.

[0046] In some embodiments, as shown in 13, the area of ​​the support portion 322 where the connecting post 312 is not provided is provided with a plurality of mounting slots for mounting the second magnetic member 321.

[0047] In some embodiments, such as Figures 5 to 8 As shown, the first magnetic chuck 221 has a mating groove 212, and the second magnetic chuck 321 has a connecting post 312. This structure not only reduces the structural thickness but also increases the connection area of ​​the two connection structures, thereby improving the stability of the connection. Furthermore, the magnetic attraction force can accelerate the mating of the connecting post 312 and the mating groove 212.

[0048] In some embodiments, in order to further improve the stability of the connection, a plurality of spaced docking grooves 212 can be provided on the first magnetic suction member 221, and a plurality of spaced connecting posts 312 can be provided on the second magnetic suction member 321 accordingly.

[0049] In some embodiments, the connection structures corresponding to the two connection methods can be set alternately.

[0050] In some embodiments, the second magnetic member 321 is provided with a protrusion corresponding to the mounting groove 21.

[0051] The connecting post 312 is L-shaped, and the mounting cavity of the mating groove 212 is L-shaped. The connecting post 312 and the mating groove 212 are mated together. Combined with the mating of the first magnetic suction member 221 and the second magnetic suction member 321, the cover 30 is firmly assembled on the shell 20.

[0052] In some embodiments, such as Figure 8 As shown, the housing 20 includes a base plate 22 and a frame 23 disposed on the outer periphery of the base plate 22. The base plate 22 and the frame 23 surround and form a receiving cavity A. The first connector 210 and the second connector 220 are disposed on the side of the frame 23 away from the receiving cavity A.

[0053] The first connector 210 and the second connector 220 are positioned on the side of the frame 23 away from the receiving cavity A, which facilitates the folding of the cover 30 relative to the housing 20 and reduces the overall thickness of the protective shell 10.

[0054] In some embodiments, such as Figure 1 and Figure 4 As shown, the cover 30 includes: a first rigid connecting part 31, a first flexible connecting part 32, and a main body part 33; a first connector 210 and a second connector 220 are disposed on the first rigid connecting part 31; the first flexible connecting part 32 is connected to one side of the first rigid connecting part 31; the main body part 33 is connected to the side of the first flexible connecting part 32 away from the first rigid connecting part 31; wherein, the main body part 33 can be folded to the side of the shell 20 away from the receiving cavity A by the deformation of the first flexible connecting part 32, and a bracket is formed by the main body part 33 to support the shell 20.

[0055] This embodiment improves the connection strength of the cover 30 by using the first rigid connecting part 31, thereby enhancing the connection stability between the cover 30 and the housing 20. Furthermore, the first flexible connecting part 32 enables the cover 30 to be folded relative to the housing 20, allowing the cover 30 to be folded open when assembled onto the housing 20, thus opening the receiving cavity A and forming the support frame of the housing 20. This embodiment enhances the functionality of the cover 30 and increases the flexibility of the protective shell 10 in use.

[0056] When the cover 30 is transferred to the housing 20, the first rigid connection part 31 can overlap with the frame of the housing 20; the first connector 210 and the second connector 220 are located inside the first rigid connection part 31 to facilitate connection with the housing 20.

[0057] In some embodiments, the main body 33 includes a plurality of second rigid connecting portions 331 and second flexible connecting portions 332, and two adjacent second rigid connecting portions 331 are connected by the second flexible connecting portions 332 to achieve relative folding between the plurality of second rigid connecting portions 331.

[0058] The main body 33 of this embodiment can be formed into a variety of different supports to achieve a variety of different support states for the housing 20.

[0059] In some embodiments, at least a portion of the plurality of second rigid connection portions 331 are arranged along the locking direction y and at least a portion are arranged along the first direction x; at least one second rigid connection portion 331 is arranged along the locking direction y with a portion of other second rigid connection portions 331, and is arranged along the locking direction y with another portion of other second rigid connection portions 331.

[0060] The second flexible connection 332 is used to realize the folding between adjacent second rigid connection 331, and it is generally of equal width and set with a narrow strip structure.

[0061] In some embodiments, such as Figure 1 As shown, the main body 33 includes five second rigid connecting parts 331. The first, second and third of the five second rigid connecting parts 331 are arranged along the first direction x, the second, fourth and fifth are arranged along the first direction x, the third and fifth are arranged along the locking direction y, a part of the fourth is arranged along the locking direction y with the second, and another part of the fourth is located on the side of the fifth away from the third along the locking direction y. The second and third are arranged in a trapezoidal shape, and the fourth and fifth are arranged in an isosceles triangle shape.

[0062] like Figures 9 to 11 As shown, different support structures can be achieved through different folding states of multiple second rigid connection parts 331.

[0063] In some embodiments, the number, shape, and arrangement of the plurality of second rigid connection portions 331 can be adjusted based on support requirements.

[0064] In some embodiments, the stiffness of the rigid connection is greater than that of the flexible connection. Stiffness refers to the force required to produce a unit deformation when an external force is applied to a structure, and it reflects the flexibility of a material; in most cases, the greater the stiffness of a material, the smaller its deformation capacity and the less flexible it is.

[0065] Furthermore, the aforementioned flexible connection can be a film layer made of TPU (thermoplastic polyurethane), which can reduce the thickness of the flexible connection, increase the deformation space of elastic deformation, and thus increase the folding performance of the cover 30.

[0066] In some embodiments, the rigid connecting part can be integrally formed with the flexible connecting part. There are various ways to achieve this integral formation, such as through heating or pressurizing; or by bonding the material layers together with adhesive or similar substances and then curing. This integral formation results in at least two material layers forming an inseparable whole under non-violent intervention; this inseparable whole is also referred to as a "one-piece integral unit."

[0067] The rigid connection part mentioned above can be formed with different materials than the flexible connection part mentioned above; of course, they can also be formed with the same material and achieve different stiffnesses by different thicknesses.

[0068] In some embodiments, such as Figure 13 As shown, magnetic strips or other magnetic attracting components can also be provided on the aforementioned rigid connection parts to improve the stability of the folded state after the cover 30 is folded, through the magnetic strips on the corresponding rigid connection parts.

[0069] In other embodiments, appropriate adjustments may be made. Figure 13 The arrangement and quantity of magnetic components can be adjusted to suit different needs.

[0070] In some embodiments, the rigid connection portion described above may be implemented using steel bars or sheets made of materials such as stainless steel.

[0071] In some embodiments, such as Figures 1 to 3 The main body 33 also has a first locking part 34 on the side away from the first flexible connecting part 32, and the housing 20 is provided with a corresponding second locking part (not shown in the figure). The first locking part 34 and the second locking part are locked together to lock the side of the cover 30 away from the first connecting component 11 and the second connecting component 12 to the side of the housing 20 away from the first connecting component 11 and the second connecting component 12, so as to securely wrap the electronic device in the receiving cavity A, thereby improving the protective ability of the protective shell 10 to protect the electronic device.

[0072] In some embodiments, at least a portion of the first locking part 34 may be made of steel bars or sheets of materials such as stainless steel.

[0073] In some embodiments, the base plate 22 includes an outer shell layer 201, an intermediate layer 202, and an inner liner layer 203 stacked sequentially; the intermediate layer 202 contains a magnet (not shown); the intermediate layer 202 includes a glass fiber resin composite layer; the inner liner layer 203 includes a TPU layer; and an aramid fiber layer (not shown) is provided on the outer side of the outer shell layer 201.

[0074] In some embodiments, the inner liner 203 includes a TPU layer and a thermally conductive buffer layer is provided on the side of the inner liner 203 facing the receiving cavity A, or the inner liner 203 includes a thermally conductive buffer layer, such as a hydrogel film.

[0075] Among them, TPU film has excellent properties such as good transparency, good formability, high melting point, and good adhesion to other film layers, which can reduce the difficulty of molding process, improve reliability and aesthetics, and enhance the visibility and excellent texture of fiber layer. Among them, aramid fiber has properties such as high strength, high modulus, high temperature resistance, and corrosion resistance, which can effectively improve the structural strength and durability of shell 20.

[0076] In some embodiments, such as Figure 8 As shown, the frame 23 includes a corner portion 81, a first side portion 82 extending along a first direction x, and a second side portion 83 extending along a second direction y1 (i.e., the direction parallel to the aforementioned latching direction y). The corner portion 81 is located at the end of the first side portion 82 in the first direction x and / or the end of the second side portion 83 in the second direction y1. The corner portion 81 protrudes at least toward the front end of the protective shell 10 along a third direction z from the first side portion 82 and / or the second side portion 83, and at least a portion of the corner portion 81 protrudes away from the outer surface of the receiving cavity A from the outer surface of the first side portion 82 and / or the outer surface of the second side portion 83. The first direction x intersects with the second direction y1, and the third direction z is perpendicular to both the first direction x and the second direction y1.

[0077] The front end of the protective casing 10 refers to the end of the electronic device facing the user when it is mounted on the protective casing 10. Typically, the control display surface of an electronic device needs to be exposed for user operation and viewing, and is easily damaged by contact or impact.

[0078] The phrase "corner portion 81 is provided at the end of the first side portion 82 in the first direction x and / or the end of the second side portion 83 in the second direction y1" means that at least one of the ends of the first side portion 82 in the first direction x and the second side portion 83 in the second direction y1 has a corner portion 81. For example, when both the end of the first side portion 82 and the end of the second side portion 83 have corner portions 81, they can share the same corner portion 81, that is, the corner portion 81 connects the first side portion 82 and the second side portion 83. For example, the corner portion 81 can also be provided at the end of the first side portion 82 away from the second side portion 83 and / or at the end of the second side portion 83 away from the first side portion 82.

[0079] Wherein, at least a portion of the corner portion 81 protrudes from the outer side of the receiving cavity A and from the outer side of the corresponding first side portion 82 and / or the outer side of the second side portion 83, meaning that at least a portion of the corner portion 81 at the end of the first side portion 83 protrudes from the outer side of the receiving cavity A and from the outer side of the corresponding first side portion 82, and at least a portion of the corner portion 81 at the end of the second side portion 83 protrudes from the outer side of the receiving cavity 84 and from the outer side of the corresponding second side portion 83.

[0080] In this embodiment, the frame 23 of the protective shell 10 has a corner portion 81 at the end of its side portion (first side portion 82 and / or second side portion 83), and the corner portion 81 is located in the extension direction (first direction x or second direction y1) of the corresponding side portion, so that the corner portion 81 and the corresponding side portion enclose a receiving cavity A for accommodating the electronic device; wherein, the corner portion 81 is provided to protrude from the corresponding side portion in a direction perpendicular to the extension direction of the corresponding side portion (third direction z) toward the front end of the protective shell 10 (the front end is usually corresponding to the control display surface of the electronic device facing the user), so that the corner portion 81 can be positioned relative to the corresponding side portion in this vertical direction. The electronic device within the side portion and frame 23 first contacts the contact object at the front end, thereby buffering the force exerted by the contact object on the corresponding side portion and the electronic device. Furthermore, at least a portion of the corner portion 81 protrudes from the outer surface of the receiving cavity A, extending beyond the outer surface of the corresponding side portion, i.e., protruding along the thickness direction of the corresponding side portion. This allows the corner portion 81 to contact the contact object before the outer surface of the corresponding side portion, thereby buffering the force exerted by the contact object along the thickness direction of the corresponding side portion on the side portion and the electronic device. In this embodiment, the side portion serves as the main body of the protective shell 10, and its thickness is not increased; therefore, the overall thickness of the protective shell 10 is not increased. Thus, through the above methods, this embodiment can improve the protective capability of the protective shell 10 for the electronic device without increasing the overall thickness of the protective shell 10.

[0081] In some embodiments, a corner portion 81 connects the end of the first side portion 82 and the end of the second side portion 83. The corner portion 81 includes a first protrusion 111 and a second protrusion 112 connected along a third direction z. The first protrusion 111 is disposed near the front end of the protective shell 10 relative to the second protrusion 112. The side of the first protrusion 111 opposite to the second protrusion 112 protrudes from the corresponding first side portion 82 and second side portion 83. At least a portion of the second protrusion 112 protrudes from the outer side of the receiving cavity A, corresponding to the outer side of the first side portion 82 and the outer side of the second side portion 83. In this way, the same corner portion 81 can simultaneously protrude from the front end of the protective shell 10 relative to the first side portion 82 and the second side portion 83 connected to it, and protrude from the outer side of the first side portion 82 and the outer side of the second side portion 83, which simplifies the structure and reduces the overall weight of the protective shell 10.

[0082] The outer side of the aforementioned side portion refers to the side portion that is away from the receiving cavity A.

[0083] In other embodiments, a similar structure may be used when the corner portion 81 is located in other positions on the protective housing 10.

[0084] In some embodiments, such as Figure 8 As shown, the corner portion 81 also includes a third protrusion 113 connected along a third direction z to the side of the second protrusion 112 opposite to the first protrusion 111; the side of the third protrusion 113 opposite to the second protrusion 112 protrudes from the first side portion 82 and the second side portion 83.

[0085] In this embodiment, at least a portion of the corner portion 81 can protrude to the rear end of the protective shell 10 relative to the first side portion 82 and the second side portion 83 connected thereto, so that the corner portion 81 can contact the contact object at the rear end relative to the electronic device disposed in the corresponding side portion and the frame 23 in the vertical direction (third direction z), thereby buffering the force of the contact object on the corresponding side portion and the electronic device, thereby improving the protective ability of the protective shell 10 to protect the electronic device.

[0086] For example, the corner portion 81 can be formed by hot pressing or other processes, so as not to increase the thickness of the protective shell 10, and to form a protrusion of the corner portion 81. Of course, the corner portion 81 can also be formed by injection molding, cutting or other processes, or by hot pressing, injection molding or cutting or other processes to form other similar corner portions 81.

[0087] In some embodiments, such as Figure 8 As shown, a buffer cavity 15 is provided on the side of the corner portion 81 near the receiving cavity A. The buffer cavity 15 can form an airbag, which can buffer the external force on the corner portion 81, thereby further improving the protective capability of the protective shell 10 for electronic devices.

[0088] In some embodiments, such as Figure 8 As shown, the buffer cavity 15 is located inside the second protrusion 112. Because the second protrusion 112 protrudes further outward toward the outer side of the frame 23, the volume of the buffer cavity 15 can be increased, thereby improving the buffering effect.

[0089] The buffer cavity 15 and the second protrusion 112 can be formed simultaneously through a stamping process; this method will not increase the thickness of the corner portion 81.

[0090] When the protective shell 10 is installed on an electronic device, the buffer cavity 15 is maintained between the four corners of the protective shell 10 and the electronic device. When the four corners are impacted, the buffer cavity 15 forms an airbag and also provides deformation space for the protective shell 10, so that the protective shell 10 can absorb the impact energy at this position and play a buffering role.

[0091] In some embodiments, such as Figure 8 As shown, the buffer cavity 15 is connected to the receiving cavity A. In this way, the thickness of the corner portion 81 can be reduced and its deformation capacity can be improved; and the manufacturing process can be simplified.

[0092] In some embodiments, a buffer thermal conductive layer (not shown) is provided on the side of the base plate 22 near the receiving cavity A to further improve the protective capability of the protective shell 10 for the electronic device and to improve the heat dissipation capability of the electronic device.

[0093] In some embodiments, a buffer thermal conductive layer (not shown) may also be provided on the side of the frame 23 near the receiving cavity A to further improve the protective capability of the protective shell 10 for the electronic device and improve the heat dissipation capability of the electronic device.

[0094] In some embodiments, the thermally conductive buffer layer may be a silicone grease TPU layer or a hydrogel film layer, etc.

[0095] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
