[0049] The protective case provided in this application is applicable to a variety of electronic devices. The electronic device can be a device that can operate independently of the housing and / or in conjunction with the housing. For example, the protective case can be used with electronic devices such as mobile phones, tablet computers, portable media players, cameras, or other portable electronic devices to provide enhanced protection for the electronic devices. The embodiments of this application will be described using a mobile phone as an example, and the protective case will also be described using a mobile phone as an example.

[0050] Example Group 1

[0051] In some embodiments, as Figures 1 to 36 As shown, the protective shell 10 includes a shell body 11, a flexible connecting portion 12, and a first button portion 13. The shell body 11 is provided with an opening 101; the first button portion 13 is integrally arranged with the shell body 11 through the flexible connecting portion 12, and is provided at the opening 101, and along the thickness direction z of the shell body 11, the projection of the first button portion 13 is located within the opening 101.

[0052] The housing body 11 defines a receiving cavity 110 for accommodating at least a portion of the electronic device 20, and the opening 101 is in communication with the receiving cavity 110. The first button portion 13 is configured to abut or be in close proximity to a function key 21 of the electronic device 20 mounted within the housing body 11, so that the function key 21 of the electronic device 20 can be triggered when a person touches the first button portion 13.

[0053] The first button portion 13 is the area where the user performs key operations. For example, in one application scenario, the protective case 10 is configured to protect an electronic device 20, which has function keys 21. When the electronic device 20 is assembled in the protective case 10, the first button portion 13 at least partially covers the function keys 21. Therefore, the user can trigger the corresponding function key 21 by pressing the first button portion 13, thereby ensuring that the function keys 21 respond normally during use.

[0054] In some embodiments, the first button portion 13 can directly abut the function key 21, or there can be a very small gap between the first button portion 13 and the function key 21, so that when the user's finger is placed on or slides on the first button portion 13, the touch response of the function key 21 of the electronic device 20 can be triggered; when the user's finger is not placed on the first button portion 13, the first button portion 13 will not apply excessive bias force to the function key 21, thereby avoiding the incorrect triggering of the function key 21 due to the above reasons.

[0055] It should be noted that, in this application, the thickness direction z of the shell body 11 refers to the thickness direction of the wall portion having the opening 101, and this direction can be parallel to the direction in which the user presses the button. For example, in one application scenario, the shell body 11 is formed with side walls 113 and a bottom wall 114, and the side walls 113 are arranged on the periphery of the bottom wall 114. The side walls 113 and the bottom wall 114 enclose each other to form a receiving cavity 110, and the receiving cavity 110 is configured to receive at least a portion of the electronic device 20. When the opening 101 is arranged on the side wall 113, the thickness direction z refers to the thickness direction of the side wall 113 of the shell body 11. In this case, the thickness direction z is perpendicular to the side wall 113, and the user presses the first button portion 13 in a direction perpendicular to the side wall 113. When the opening 101 is arranged on the bottom wall 114, the thickness direction z refers to the thickness direction of the bottom wall 114. In this case, the thickness direction z is perpendicular to the bottom wall 114, and the user presses the first button portion 13 in a direction perpendicular to the bottom wall 114.

[0056] In other embodiments, the shell body 11 may include a top wall, and the top wall, the bottom wall 114 and the side walls 113 together form a fully enclosed accommodating cavity 110 to completely enclose the electronic device 20 .

[0057] The position of the opening 101 corresponds to the function key 21 of the electronic device 20. For example, when the function key 21 of the electronic device 20 is set on the side, the opening 101 is correspondingly opened on the side wall of the shell body 11. When the function key 21 of the electronic device is set on the back, the opening 101 is correspondingly opened on the bottom wall of the shell body 11.

[0058] The accommodating cavity 110 is used to accommodate and couple the electronic device 20. One or more coupling structures for holding and coupling the electronic device 20 in the accommodating cavity 110 may also be provided in the accommodating cavity 110. The coupling structure includes but is not limited to flexures, guide rails, channels, buckles, magnets, and friction couplings. It is understandable that the coupling between the protective shell 10 and the electronic device 20 is continuous, ensuring that the protective shell 10 and the electronic device 20 are not accidentally separated during use. It is further understandable that the protective shell 10 and the electronic device 20 can be coupled in a removable manner, so that the electronic device 20 can be removed according to the needs of the user. In this way, the coupling between the protective shell 10 and the electronic device 20 is reversible, so that each can be restored to the state before they were coupled.

[0059] In some embodiments, the protective shell 10 can be an integral single structure or can be formed of multiple discrete parts (of the same or different materials). For example, the back side of the back plate of the protective shell 10 can be formed of a rigid material, while other parts of the protective shell 10 (such as the frame) can be formed of an elastic material. Or the protective shell 10 includes an upper shell and a lower shell, or the protective shell 10 includes a left shell and a right shell. In some embodiments, an additional layer can be provided in the accommodating cavity 110. The additional layer can be a material for contacting the electronic device 20, including but not limited to microfiber, fabric, foam, rubber, etc. The additional layer can also use materials for heat dissipation of the shell and / or avoiding damage to the electronic device 20.

[0060] It should be noted that after the molding process of the protective shell 10 is completed, in the thickness direction z of the shell body 11, the first button part 13, the flexible connection part 12 and other components located near the opening 101 may be displaced due to molding processes such as hot pressing. Therefore, in this application, the accompanying drawings are only used as a schematic diagram of the arrangement of the layered structure of the components of the protective shell 10.

[0061] The flexible connection portion 12 is capable of connecting the first button portion 13 to the case body 11, so that the first button portion 13 and the case body 11 are integrally connected. Furthermore, the force-bearing portion of the flexible connection portion 12 is capable of displacement relative to the case body 11. Therefore, when a force is applied to the first button portion 13, relative displacement occurs between the flexible connection portion 12 and the case body 11. The projection of the first button portion 13 along the thickness direction z of the case body 11 is located within the opening 101. Therefore, a user can press the first button portion 13 to cause it to displace along the thickness direction z of the case body 11, thereby operating the electronic device 20 within the protective case 10.

[0062] Among them, the projection of the first button portion 13 along the thickness direction z of the shell body 11 is located within the opening 101, which means that the first button portion 13 is located within the opening 101, or the first button portion 13 is located on the inner side or outer side of the opening 101 along the thickness direction z of the shell body 11 and faces the opening 101.

[0063] There are various ways to achieve this integration. For example, heating or pressurizing the at least two material layers causes the relevant substances to melt, flow to a specific location under pressure or a mold, and then solidify under the influence of temperature or pressure. Alternatively, the material layers can be bonded together using adhesive or other methods and then solidified. The integration mentioned here creates a whole that cannot be separated without violent intervention between the at least two material layers. This indivisible whole is also called a "one-piece whole."

[0064] In some embodiments, the flexible connection portion 12 and the shell body 11 are integrally formed by hot pressing. In this way, the connection strength between the flexible connection portion 12 and the shell body 11 can be ensured while simplifying the manufacturing process and improving production efficiency.

[0065] In some embodiments, the flexible connection portion 12 and the housing body 11 can be two-shot injection molded. For example, if the flexible connection portion 12 and the first button portion 13 are made of different types of thermoplastic resin, the flexible connection portion 12, the first button portion 13, and the housing body 11 can be two-shot injection molded. This can reduce labor and logistics costs and avoid tolerance accumulation caused by separate assembly.

[0066] Among them, the flexible connection part 12 is easy to deform under the action of external force, which can improve the flexibility of the relative displacement between the first button part 13 and the shell body 11, and can improve the sensitivity and reliability of external operation on the electronic device 20; further, the shell body 11 can form a rigid area of ​​the protective shell 10, and can achieve effective protection for the electronic device 20 as a whole; further, the shell body 11 and the first button part 13 can be integrally formed, which can improve the structural stability of the protective shell 10, save material costs, and is conducive to the miniaturization of the combined structure formed by the protective shell 10 and the electronic device 20.

[0067] In this way, on the one hand, the first button part 13 provided at the opening 101 of the shell body 11 is connected to the shell body 11 through the flexible connection part 12, which can improve the movement ability of the first button part 13 relative to the shell body 11, so that the protective shell 10 has a local flexible area, which can improve the control feel of the first button part 13 and reduce the control influence of the shell body 11 on the first button part 13, thereby improving the control accuracy of the electronic device 20; on the other hand, the first button part 13 is provided at the opening 101 of the shell body 11 and the first button part 13 is connected to the shell body 11 through the flexible connection part 12, which can increase the sealing of the opening 101 through the first button part 13 and the flexible connection part 12, thereby improving the problem that the corresponding button of the electronic device 20 is exposed and cannot be effectively protected; on the other hand, the shell body 11, the flexible connection part 12, and the first button part 13 are integrally formed, which can improve the structural stability of the protective shell 10, improve the problems of insufficient connection strength and easy falling off caused by split assembly, and further improve the protection capability of the electronic device 20.

[0068] In some embodiments, the rigidity of the shell body 11 is greater than the rigidity of the flexible connection 12. Rigidity refers to the amount of force required to produce a unit of deformation when an external force is applied to a structure and reflects the flexibility of the material. In most cases, the stiffer the material, the less deformable it is and the less flexible it is.

[0069] The stiffness of the shell body 11 refers to the force required to produce a unit deformation of the shell body 11 when an external force is applied, while the stiffness of the flexible connection 12 refers to the force required to produce a unit deformation of the flexible connection 12 when an external force is applied. When the same force is applied to the shell body 11 and the flexible connection 12, the deformation of the shell body 11 is smaller than the deformation of the flexible connection 12.

[0070] The rigidity of the shell body 11 is greater than that of the flexible connection part 12, which can facilitate the pressing and rebound operation of the first button part 13, making the pressing and rebound feedback of the first button part 13 clearer and the touch more comfortable; and the flexible connection part 12 is easy to deform under the action of external force, which can reduce the difficulty of disassembly and assembly of the protective shell 10; further, the shell body 11, as the main body of the protective shell 10, can achieve effective protection for the electronic device 20 as a whole.

[0071] The material of the shell body 11 and the material of the flexible connection part 12 can be different to achieve different stiffnesses. For example, the shell body 11 can be made of fiber material or a high elastic modulus material such as polycarbonate (PC); the flexible connection part 12 can be made of a low elastic modulus material such as thermoplastic polyurethane (TPU), rubber, or silicone. Alternatively, the material of the shell body 11 and the flexible connection part 12 can be the same, for example, TPU, but the stiffness of the shell body 11 can be greater than that of the flexible connection part 12 by using TPU of different stiffness or by making the thickness of the shell body 11 greater than that of the flexible connection part 12.

[0072] It can be understood that in some embodiments, the stiffness of each region of the flexible connection portion 12 can be kept consistent, and in other embodiments, the stiffness of each region can be inconsistent, which is not specifically limited.

[0073] In some embodiments, the rigidity of all regions of the flexible connection portion 12 is uniform, or the rigidity gradually increases from the first button portion 13 to the shell body 11 , so as to increase the connection stability between the flexible connection portion 12 and the shell body 11 during deformation.

[0074] In some embodiments, the stiffness of all regions of the shell body 11 is consistent, or the stiffness gradually increases from the opening 101 to the region away from the opening 101, so as to increase the connection stability between the flexible connection portion 12 and the shell body 11 during deformation.

[0075] In some embodiments, the rigidity of the first button portion 13 is smaller than that of the shell body 11 , so that the deformation capability of the first button portion 13 is greater than that of the shell body 11 , which facilitates the user's pressing operation.

[0076] In some embodiments, the elasticity of the flexible connection portion 12 is greater than that of the shell body 11. In this way, the deformation ability and deformation recovery force of the flexible connection portion 12 relative to the shell body 11 can be improved, thereby improving the clarity and touch feel of the press-and-rebound operation of the first button portion 13.

[0077] In some embodiments, the elasticity of the first button portion 13 is less than that of the flexible connection portion 12. This can alleviate the problem of the first button portion 13 deforming after long-term use, failing to align with the function key 21 of the electronic device 20, resulting in reduced sensitivity or even failure. Furthermore, the hardness of the first button portion 13 is greater than that of the flexible connection portion 12. This improves the wear resistance of the first button portion 13.

[0078] It is understood that the case body 11 is used to protect electronic devices and therefore needs to be impact-resistant, wear-resistant, and lightweight. The flexible connection portion 12, acting as a spring carrier for the first button portion 13, needs to be highly elastic and fatigue-resistant. Therefore, the case body 11 and the flexible connection portion 12 are made of suitable materials based on different usage requirements. By complementing the performance of the materials in each component, the balance between the function and user experience of the protective case can be maximized.

[0079] In some embodiments, the flexible connection portion 12 is in a planar tensioned state and is located within the opening 101. Compared to configuring the flexible connection portion 12 in a pleated shape, the rebound of the flexible connection portion 12 in a planar tensioned state is more distinct, thus making the first button portion 13 more resilient when pressed, and providing a better pressing feel.

[0080] In some embodiments, the extension direction of the flexible connection portion 12 is consistent with the extension direction of the outer surface of the shell body 11. In this way, the flexible connection portion 12 can be stretched in a plane, which can enhance the rebound effect of the flexible connection portion 12 and further improve the pressing feel of the first button portion 13.

[0081] In some embodiments, the flexible connection portion 12 is made of a light-transmitting material. This allows for light transmission in certain scenarios, such as when the function keys of an electronic device are illuminated, thereby enhancing the visual experience of the protective case. In other embodiments, the flexible connection portion 12 can also be made of an opaque material, or a light-shielding layer can be applied to the outer surface of the flexible connection portion 12.

[0082] In some embodiments, the first button portion 13 further includes an outer layer, which forms the outer surface of the first button portion 13. This outer layer has a lower coefficient of friction than the flexible connection portion 12. This outer layer can be made of a material with a low coefficient of friction that facilitates sliding touch. For example, it can be a resin-impregnated and polished aramid fiber layer, or a smooth, wear-resistant material such as sapphire glass. Alternatively, the outer layer can be made of a polymer material with a low coefficient of friction and can be formed by spraying it onto the outer surface of the first button portion 13. By making the coefficient of friction of the outer layer lower than that of the flexible connection portion 12, the friction force applied when a user touches the first button portion 13 can be reduced. This results in a smoother touch feel at the first button portion 13, which facilitates smoother operation of the electronic device's function keys using the first button portion 13. In some embodiments, the outer layer is made of the same material as the case body 11. This ensures that the first button portion 13 and the case body 11 have a consistent appearance, enhancing the overall appearance of the protective case 10.

[0083] Furthermore, the outer layer and the shell body 11 are both made of aramid fiber. In this way, while ensuring the overall consistency of the appearance of the protective shell 10, the outer surfaces of the outer layer and the shell body 11 can be made wear-resistant, smooth, and easy to slide and touch.

[0084] In some embodiments, the outer layer is a smooth layer, forming the outer surface of the first button portion 13. This smooth layer can be made of a material with a low coefficient of friction that facilitates sliding and touching. For example, the smooth layer can be made of a resin-impregnated and polished aramid fiber layer, or a smooth and wear-resistant material such as sapphire glass. The provision of the smooth layer can enhance the smoothness of a user's operation of the electronic device's function keys by touching the first button portion 13.

[0085] In some embodiments, the outer layer is a wear-resistant layer formed on the outer surface of the first button portion 13. Specifically, the wear-resistant layer can be made of a wear-resistant material such as aramid fiber or sapphire glass. The provision of the wear-resistant layer can enhance the scratch resistance of the first button portion 13, thereby ensuring the appearance stability of the first button portion 13.

[0086] It should be noted that the outer layer can be provided with a smooth layer or a wear-resistant layer alone, or can be provided with a smooth and wear-resistant layer in combination, so as to improve the smoothness of the operation of the function keys of the electronic device by the first button part 13 or have the advantages of being wear-resistant, smooth, and easy to slide and touch, all of which fall within the scope of this embodiment and are not limited here.

[0087] In one application scenario, the sensor button 211 of the electronic device 20 is located on the side. When assembled, the position of the sensor button 211 corresponds to the position of the first button portion 13 on the side wall 113 of the protective case 10. The sensor button 211 of the electronic device 20 protrudes from the side of the electronic device 20. This creates a groove between the inner surface of the first button portion 13 and the inner surface of the case body 11 to accommodate the protruding sensor button 211. This groove also creates a deformation space for the flexible connection portion 12, thereby improving the operational reliability of the entire first button portion 13.

[0088] In some embodiments, as Figure 5 、 Figure 35 and Figure 36 , the first button portion 13 includes a fiber layer 41 .

[0089] In some application scenarios, the first button portion 13 is a single-layer structure, including only the fiber layer 41, for example, Figure 5 、 Figure 35 , Figure 5 The layered structure of the protective shell structure before the molding process in one embodiment is shown. Figure 35 The cross-sectional structure of the protective shell after the molding process in one embodiment is shown, wherein the first button portion 13 includes a single-layer fiber layer 41; in other application scenarios, such as Figure 36 As shown, Figure 36 It is a schematic diagram of the cross-sectional structure of another embodiment of the partial structure of the protective shell of the present application after the molding process; the first button part 13 includes a button body 131 and a fiber layer 41, and the fiber layer 41 covers the side of the button body 131 facing away from the electronic device. The user can press the fiber layer 41 to press the first button part 13.

[0090] In this way, the fiber layer 41 can be used to improve the touch feel of the first button part 13 and enhance the user experience; further, the provision of the fiber layer 41 facilitates the improvement of the appearance of the first button part 13 and can enhance the overall aesthetics of the protective shell 10.

[0091] In some embodiments, the fiber layer 41 may further wrap around the outer periphery of the button body 131 , or may be disposed on both the inner and outer sides of the button body 131 .

[0092] In some embodiments, as Figure 5 As shown, along the thickness direction z of the shell body 11 , the projection of the flexible connection portion 12 covers the projection of the first button portion 13 and the opening 101 .

[0093] Among them, along the thickness direction z of the shell body 11, the projection of the flexible connection part 12 covers the projection of the first button part 13 and the opening 101, which means that the projection of the flexible connection part 12 toward the thickness direction z of the shell body 11 covers the projection of the first button part 13 and the opening 101, and does not limit whether the first button part 13 is completely located in the opening 101.

[0094] The beneficial effect of the above-mentioned arrangement is that the flexible connection part 12 covers the first button part 13 and the opening 101 in the thickness direction z, which facilitates the connection between the flexible connection part 12 and the side wall 113 of the opening 101, and realizes the connection between the flexible connection part 12 and the first button part 13, which can improve the connection stability between the flexible connection part 12 and the first button part 13. At the same time, the covering design of the flexible connection part 12 can effectively reduce the interference of external factors such as dust on the first button part 13, which can improve the reliability of the first button part 13 and improve the protective effect of the protective case 10 on the electronic device 20.

[0095] In some embodiments, as Figure 6 As shown, along the thickness direction z of the shell body 11, the flexible connection part 12 partially covers the first button part 13 to achieve connection with the first button part 13; or as shown in FIG. Figure 7 As shown, along the thickness direction z of the shell body 11, the flexible connection portion 12 does not cover the first button portion 13 and is connected to the outer periphery of the first button portion 13. For example, the flexible connection portion 12 completely or partially surrounds the outer periphery of the first button portion 13, and the side of the flexible connection portion 12 facing away from the first button portion 13 is connected to the shell body 11, thereby connecting the first button portion 13 and the shell body 11 into an integrated structure.

[0096] It should be noted that the improvement of the flexible connection portion 12 is not limited to the embodiment in which the shell body is a double-layer structure. In the embodiment in which the shell body is a single-layer structure or a three-layer or above structure (not shown), the improvement can still be referred to. Figures 5 to 7 The illustrated embodiment improves the flexible connection portion 12 .

[0097] In order to improve the structural stability of the protective shell 10, the connection method between the flexible connection part 12 and the shell body 11 can also be improved. For example, in some embodiments, Figure 5As shown, the shell body 11 includes a first supporting layer 111 and a second supporting layer 112, and the first supporting layer 111 is provided with a first opening 1011; the second supporting layer 112 is laminated with at least a partial area of ​​the first supporting layer 111 along the thickness direction z of the shell body 11, and the second supporting layer 112 is provided with a second opening 1012, and along the thickness direction z, the first opening 1011 and the second opening 1012 at least partially overlap to form an opening 101; at least a portion of the flexible connection part 12 is laminated between the first supporting layer 111 and the second supporting layer 112; wherein, the stiffness of the first supporting layer 111 and the stiffness of the second supporting layer 112 are both greater than the stiffness of the flexible connection part 12. In this way, the local resistance of the first support layer 111 and the second support layer 112 to the invasion of foreign objects is greater than the local resistance of the flexible connection part 12 to the invasion of foreign objects; the first support layer 111 and the second support layer 112 together form the shell body 11 of the protective shell; the first support layer 111 and the second support layer 112 can be the outer layer material and the inner layer material forming the shell body 11, the first support layer 111 and the second support layer 112 can be a material with high rigidity, the first support layer 111 and the second support layer 112 can be a hard thermosetting resin material; the first support layer 111 and the second support layer 112 can also be a material with a certain elasticity, such as silicone or TPU. In a specific embodiment, the first support layer 111 and the second support layer 112 can be made of aramid fiber material, which is woven from aramid fibers, and the aramid fiber material has high rigidity and hardness by being impregnated with epoxy resin. The first support layer 111 and the second support layer 112 can be formed into the shell body 11 by hot pressing.

[0098] In some embodiments, the elasticity of the first supporting layer 111 and the second supporting layer 112 is less than the elasticity of the flexible connecting portion 12, which enables the flexible connecting portion 12 to be easily deformed and restored, thereby realizing the operation of the electronic device 20 in the protective shell 10, while the rigid layer is not easily deformed, thereby improving the protection effect of the electronic device 20.

[0099] The first opening 1011 and the second opening 1012 completely or partially overlap. The at least partial overlap of the first opening 1011 and the second opening 1012 means that the projections of the opening 101 area of ​​the first opening 1011 and the opening 101 area of ​​the second opening 1012 along the thickness direction z overlap, thereby reducing the obstruction of the second opening 1012 by the peripheral area of ​​the first opening 1011 and the first opening 1011 by the peripheral area of ​​the second opening 1012. Thus, the aforementioned opening 101 of the shell body 11 can be formed in the overlapping portion of the first and second supporting layers 111 and 112. The first and second supporting layers 111 and 112 completely or partially overlap, respectively, without specific limitation.

[0100] For example, in some embodiments, Figure 5 As shown, the first opening 1011 and the second opening 1012 have the same size and are completely aligned, and the projection of the flexible connection portion 12 along the thickness direction z covers the first opening 1011 and its peripheral area, the second opening 1012 and its peripheral area. For example, in some embodiments, Figure 8 As shown, the size of the first opening 1011 is larger than that of the second opening 1012, and along the thickness direction z, the two at least partially overlap, and the projection of the flexible connection portion 12 along the thickness direction z covers the first opening 1011 and its peripheral area, and the second opening 1012 and its peripheral area. For example, in some embodiments, Figure 9 As shown, the size of the first opening 1011 is smaller than that of the second opening 1012, and the two at least partially overlap along the thickness direction z. The projection of the flexible connection part 12 along the thickness direction z covers the first opening 1011 and its peripheral area, and the second opening 1012 and its peripheral area.

[0101] Among them, at least a portion of the flexible connection portion 12 is laminated and disposed between the first support layer 111 and the second support layer 112. The flexible connection portion 12 can be fixed by the first support layer 111 and the second support layer 112, and a tight connection between the flexible connection portion 12 and the first support layer 111 and the second support layer 112 can be achieved, thereby improving the connection reliability of the flexible connection portion 12 and the shell body 11, and improving the positional stability and deformation controllability of the flexible connection portion 12 when subjected to force. Furthermore, the flexible connection portion 12 can be a film layer made of TPU material, which can reduce the thickness of the flexible connection portion 12 and increase the deformation space for elastic deformation, thereby increasing the displacement distance of the first button portion 13 when pressed and improving the rebound force.

[0102] In other embodiments, when the flexible connection portion 12 adopts other structural forms, the flexible connection portion 12 can also be improved in a similar manner to achieve a fixed connection between the flexible connection portion 12 and the first supporting layer 111 and the second supporting layer 112, thereby achieving a connection between the flexible connection portion 12 and the shell body 11. Therefore, the laminated structure design can effectively improve the connection stability between the flexible connection portion 12 and the shell body 11 and facilitate subsequent processing.

[0103] In other embodiments, the shell body 11 may also include only the first supporting layer 111, and the first supporting layer 111 and at least a portion of the flexible connecting portion 12 are stacked to facilitate the flexible connecting portion 12 and the first supporting layer 111 to be tightly combined by hot pressing or other molding processes.

[0104] In order to improve the connection stability between the flexible connection portion 12 and the first button portion 13, the flexible connection portion 12 may be further improved. Figure 10 As shown, the flexible connection portion 12 includes a first flexible layer 301 and a second flexible layer 302 ; along the thickness direction z, the first flexible layer 301 covers the outer side of the first button portion 13 ; along the thickness direction z, the second flexible layer 302 covers the inner side of the first button portion 13 .

[0105] Specifically, the projection of the first flexible layer 301 along the thickness direction z of the shell body 11 covers the first button portion 13, while the projection of the second flexible layer 302 along the thickness direction z of the shell body 11 covers the first button portion 13. It can be understood that the first flexible layer 301, the first button portion 13, and the second flexible layer 302 are stacked sequentially along the thickness direction z of the shell body 11. The first flexible layer 301 and the second flexible layer 302 sandwich the first button portion 13 through the stacked structure, which improves the connection between the first button portion 13 and the flexible connection portion 12 and protects the first button portion 13 from displacement or damage during use, thereby further enhancing the stability and durability of the overall structure. The second flexible layer 302 inside the first button portion 13 can also improve or reduce marks left on the first button portion 13 due to long-term contact with the function keys 21 of the electronic device 20.

[0106] In some embodiments, as Figure 11 As shown, Figure 11 yes Figure 5 In the enlarged structural diagram of area B in the embodiment, there is a gap d between the first button portion 13 and the inner wall of the opening 101 .

[0107] Among them, a gap d is provided between the first button portion 13 and the inner wall of the opening 101, which means that the projection of the first button portion 13 along the thickness direction z of the shell body 11 is located within the opening 101, and there is a gap d between the projection and the inner wall of the opening 101; it can also be understood that in the vertical plane of the thickness direction z of the shell body 11, there is a gap d between the first button portion 13 and the inner wall of the opening 101. When the first button portion 13 is pressed along the thickness direction z, the gap d can provide a certain buffer space, thereby reducing the collision and friction between the first button portion 13 and the shell body 11.

[0108] Among them, the first button part 13 can maintain a certain gap d with the inner wall of the opening 101 through the flexible connection part 12, ensuring the flexibility of button operation, reducing the risk of button jamming, and reducing the friction between the first button part 13 and the shell body 11 when the user performs button operation.

[0109] In some embodiments, the first button portion 13 is positioned within the opening, and an annular gap d is formed between the outer peripheral wall of the first button portion 13 and the inner wall of the opening 101. The flexible connection portion 12 is integrally formed with the first button portion 13 to cover or fill the gap d. Furthermore, the design of the flexible connection portion 12 covering or filling the first annular gap d effectively reduces interference with the first button portion 13 from external factors such as dust, thereby improving the reliability of the first button portion 13 and enhancing the protective effect of the protective case 10 on the electronic device 20.

[0110] In some embodiments, as Figure 29 As shown, Figure 29 This is a schematic cross-sectional structure diagram of an embodiment of the partial structure of the protective shell of the present application after the molding process. The inner wall 71 of the first button part 13, the inner wall 72 of the opening 101 and the part 73 of the flexible connection part 12 located in the gap form a groove 70; the groove 70 provides space for the deformation of the flexible connection part 12.

[0111] Figure 29 The cross-sectional structure of a part of the protective shell after the molding process in one embodiment is shown. By providing the groove 70, deformation space can be provided for the flexible connection part 12, thereby reducing the difficulty of pressing for the user and improving the user's key pressing experience.

[0112] In some embodiments, the flexible connection 12 includes an annular or quasi-annular region covering the gap d.

[0113] Specifically, the projection of the flexible connection portion 12 in the thickness direction z covers the gap d. The area covered by the flexible connection portion 12 can be an annular area or a quasi-annular area, such as a square ring or a circular ring, without limitation. The covering design of the flexible connection portion 12 can effectively reduce the interference of external factors such as dust on the first button portion 13, thereby improving the reliability of the first button portion 13 and enhancing the protective effect of the protective case 10 on the electronic device 20.

[0114] Furthermore, the flexible connection portion 12 in the annular or quasi-annular region is in a sheet-like structure. This allows the flexible connection portion 12 to be stretched and stretched in a flat surface. Compared to a wrinkled portion of the flexible connection portion 12 in the annular or quasi-annular region, the sheet-like flexible connection portion 12 has a clearer rebound, resulting in a more pronounced rebound feedback when the first button portion 13 is pressed, and a better pressing feel.

[0115] In other embodiments, the portion of the flexible connection portion 12 in the annular or quasi-annular region may also be configured to be corrugated, thereby increasing the deformation range of the flexible connection portion 12 .

[0116] In order to further improve the flexibility and stability of key operations, in some embodiments, such as Figure 11 As shown, the width of the gap d between the first button portion 13 and the inner wall of the opening 101 is 0.5 mm to 2 mm.

[0117] The width of the gap d refers to the distance between the projection of the first button portion 13 along the thickness direction z of the case body 11 toward the opening 101 and the inner wall 72 of the opening 101, within a plane perpendicular to the thickness direction z of the case body 11. For example, in one application scenario, the case body 11 forms a closed opening 101, and the projection of the first button portion 13 along the thickness direction z of the case body 11 toward the opening 101 is located within the opening 101. The gap d surrounds the first button portion 13, forming an annular space between the first button portion 13 and the inner wall 72 of the opening 101. The width of the annular space is the width of the gap d.

[0118] The larger the gap d, the more flexible the key operation. However, an excessively large gap d may reduce the positional stability of the first key portion 13. A too small gap d may increase friction, making the key operation too stiff, increasing friction and affecting the user experience. Therefore, the width of the gap d is set to 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm or 2.0mm, etc., to improve the flexibility of key operation and the positional stability of the first key portion 13.

[0119] In some embodiments, the width of the gap d between the first button portion 13 and the inner wall 72 of the opening 101 is 0.8 mm, so as to further improve the comfort and durability of the key operation, so that the user can get smooth feedback under different key press forces.

[0120] In some embodiments, the ratio of the area of ​​the flexible connection portion 12 at the gap d to the area of ​​the first button portion 13 is 0.3-3.35.

[0121] Among them, the outer peripheral area of ​​the opening 101 is connected to the first button part 13 through the flexible connection part 12. The area of ​​the flexible connection part 12 at the gap d refers to the projected area of ​​the flexible connection part 12 at the gap d in the vertical plane of the thickness direction z of the shell body 11; the area of ​​the first button part 13 refers to the projected area of ​​the first button part 13 in the vertical plane.

[0122] The area can be 0.3, 0.4, 0.55, 0.861, 0.945, 1, 1.02, 1.542, 1.6, 1.8, 2, 2.35, 2.5, 2.61, 3, 3.05, 3.1, 3.15, 3.2, 3.25, 3.3, 3.35, etc., without limitation. For example, the area of ​​the flexible connection portion 12 at the gap d is 17.927 mm 2 The area of ​​the first button portion 13 is 31.14 mm 2 , the area ratio is 0.576; for example, the area of ​​the flexible connection portion 12 at the gap d is 81.13mm 2 The area of ​​the first button portion 13 is 31.14 mm 2 , the area ratio is 2.605; for example, the area of ​​the flexible connection portion 12 at the gap d is 21.068mm 2 The area of ​​the first button portion 13 is 68.565 mm 2 , the area ratio is 0.307; for example, the area of ​​the flexible connection portion 12 at the gap d is 93.698mm 2 The area of ​​the first button portion 13 is 68.565 mm 2 , the area ratio is 1.367.

[0123] This arrangement can improve the key flexibility at the first key portion 13 while ensuring the key area of ​​the first key portion 13, providing a better pressing feel, improving the comfort and durability of key operation, and enhancing the user's key experience.

[0124] In some embodiments, the thickness of the flexible connection portion 12 at the gap d is smaller than the thickness of the first button portion 13 .

[0125] The thickness of the flexible connection portion 12 refers to the thickness of the flexible connection portion 12 in the thickness direction z of the shell body 11, and the thickness of the first button portion 13 refers to the thickness of the first button portion 13 in the thickness direction z of the shell body 11. The thickness of the flexible connection portion 12 is less than the thickness of the first button portion 13, which can further enhance the flexibility of the flexible connection portion 12 in elastic deformation, thereby improving the displacement flexibility of the first button portion 13.

[0126] In other embodiments, the thickness of the flexible connection portion 12 at the gap d may also be equal to the thickness of the first button portion 13 to improve the thickness consistency of the overall structure of the protective shell 10 .

[0127] In some embodiments, the thickness of the flexible connection portion 12 is 0.1 mm to 0.5 mm.

[0128] In some embodiments, the thickness of the flexible connection portion 12 at the gap d is 0.1 mm to 0.5 mm.

[0129] For example, the thickness of the flexible connection portion 12 at the gap d is 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm, etc., to further improve the elastic deformation ability of the flexible connection portion 12 and reduce the interference of the flexible connection portion 12 on user operations.

[0130] In some embodiments, the first button portion 13 is in an elongated strip shape, and the opening 101 is configured to mimic the shape of the first button portion 13 .

[0131] The first button portion 13 can be configured in a circular, rectangular, or racetrack shape. Of course, the first button portion 13 is configured to mimic the function keys of an electronic device for easier user identification and observation. By aligning the opening 101 with the first button portion 13, the extended shape of the gap d matches the outer contour of the first button portion 13, ensuring visual consistency and improving force uniformity between the inner and outer rings of the flexible connection portion 12.

[0132] In some embodiments, as Figure 4 As shown, the length h of the first button portion 13 is 15 mm to 19 mm.

[0133] The length h of the first button portion 13 refers to the length of the long side of the first button portion 13 in a plane perpendicular to the thickness direction z of the shell body 11. For example, in one application scenario, the first button portion 13 is disposed on the side wall 113 of the shell body 11. The first button portion 13 has a substantially rectangular structure with a long side and a short side. The length h of the long side is 15 mm, 16 mm, 16.2 mm, 16.5 mm, 16.7 mm, 17 mm, 17.1 mm, 17.3 mm, 17.5 mm, 17.8 mm, 18 mm, or 19 mm, etc.

[0134] In some application scenarios, the length h of the first button portion 13 may be fine-tuned based on the size of the function key 21 of the electronic device 20 .

[0135] If the length h of the first button portion 13 is too long, it will affect the convenience of user operation and it will be difficult to accurately control the function key 21 corresponding to the electronic device 20 by pressing the first button portion 13; if the length h of the first button portion 13 is too short, it will not be able to effectively cover the function key 21 area of ​​the electronic device 20 and it will be inconvenient for the user to press the button. Therefore, the above setting can effectively improve the user's operating convenience.

[0136] In some embodiments, the length h of the first button portion 13 is 17.5 mm, so that the user can accurately trigger the corresponding function key 21 of the electronic device 20 during operation, thereby improving the user experience.

[0137] In some embodiments, as Figure 4 As shown, the width w of the first button portion 13 is 1.5 mm to 4 mm.

[0138] The width w of the first button portion 13 refers to the length of the short side of the first button portion 13 in a plane perpendicular to the thickness direction z of the shell body 11. For example, in one application scenario, the first button portion 13 is disposed on the side wall 113 of the shell body 11. The first button portion 13 has a substantially rectangular structure with a long side and a short side. The length of the short side is 1.5 mm, 1.8 mm, 2 mm, 2.1 mm, 2.3 mm, 2.5 mm, 3 mm, 3.2 mm, 3.3 mm, 3.5 mm, 3.6 mm, 3.7 mm, or 4 mm, etc.

[0139] In some application scenarios, the width w of the first button portion 13 may be fine-tuned based on the size of the function key 21 of the electronic device 20 .

[0140] If the width w of the first button portion 13 is too large, the overall size of the protective case 10 will be increased, making it inconvenient for the user to operate; if the width w of the first button portion 13 is too small, it will not effectively cover the function key 21 area of ​​the electronic device 20. Therefore, the above configuration can effectively improve the user's operating convenience.

[0141] It is understandable that the above-mentioned length and width range of the first button portion 13 is the optimal range obtained through experiments, and some non-creative adjustments to the above-mentioned range should also fall within the scope of protection of this patent.

[0142] In some embodiments, the width of the annular or quasi-annular region, ie, the width of the flexible connection portion 12 at the gap d, is 0.5 mm to 2 mm.

[0143] The larger the width of the annular or quasi-annular area, the more flexible the key operation. However, if it is too large, the positional stability of the first key portion 13 may be reduced; if it is too small, the key operation may be too stiff, increasing friction and affecting the user experience. Therefore, the width of the annular or quasi-annular area is set to 0.5mm, 0.55mm, 0.7mm, 0.85mm, 0.9mm, 1.0mm, 1.15mm, 1.2mm, 1.3mm, 1.45mm, 1.5mm, 1.6mm, 1.75mm, 1.8mm, 1.95mm or 2.0mm, etc., to improve the flexibility of key operation and the positional stability of the first key portion 13.

[0144] In some embodiments, the width of the annular or quasi-annular area is 0.8 mm, so as to further improve the comfort and durability of key operation, so that users can get smooth feedback under different key press forces.

[0145] In some embodiments, as Figure 3 As shown, the protective case 10 is configured to protect an electronic device 20 . The electronic device 20 is provided with function keys 21 . When the electronic device 20 is assembled in the protective case 10 , the first button portion 13 at least partially covers the function keys 21 .

[0146] Among them, the first button portion 13 covers at least part of the function keys 21, which means that after the protective shell 10 and the electronic device 20 are assembled, the projection of the first button portion 13 toward the electronic device 20 along the thickness direction z of the shell body 11 covers one or more (two or more) of the multiple function keys 21 on the electronic device 20, so that the first button portion 13 is set corresponding to part of the function keys 21.

[0147] In this embodiment, a first button portion 13 is set at the position of the function key 21 of the protective shell 10 and the electronic device 20. Since the first button portion 13 is connected to the opening 101 by the flexible connecting portion 12, the first button portion 13 has a strong ability to be displaced by external force. The first button portion 13 can transmit external operations faster and more accurately, thereby improving the sensitivity and reliability of the external operation function key 21.

[0148] Furthermore, when the protective shell 10 is disassembled and assembled with the electronic device 20 , the disassembly and assembly operation can also be performed at the first button portion 13 , and the difficulty of disassembly and assembly of the protective shell 10 can be reduced by the displacement of the first button portion 13 and the deformation ability of the flexible connection portion 12 .

[0149] Compared with the solution in the related art of exposing the function keys 21 of the electronic device 20 by setting through holes, the protective shell 10 of this embodiment can not only cover the function keys 21 of the electronic device 20 through the first button part 13 and the flexible connection part 12, so that the function keys 21 are not exposed, but also protect the function keys 21; at the same time, through the design of the protective shell 10, the interference of the protective shell 10 on the user's operation of the function keys 21 is reduced.

[0150] In some embodiments, the function key 21 includes a sensor button 211. The sensor button 211 can be a touch-sensitive sensor button 211, so that a human body can control or call up corresponding functions of the electronic device 20 by touching the sensor button 211, such as a shooting function, a near field communication (NFC) function, etc.

[0151] In some embodiments, a sensor button 211 is provided on the outer surface of the electronic device 20 . The first button portion 13 is attached to the outer surface of the sensor button 211 to protect the sensor button 211 and facilitate the user to operate the sensor button 211 by touching the first button portion 13 .

[0152] The sensing button 211 may include a capacitive sensing button 211 or a resistive sensing button 211 .

[0153] In some embodiments, the sensing button 211 includes a capacitive sensing button 211. The deformability of the flexible connection portion 12 and the displacement of the first button portion 13 can be utilized to transmit an external pressing operation to the capacitive sensing button 211, thereby realizing the first function of the electronic device 20 through the pressing operation. Even if the first button portion 13 is an insulator, a capacitive coupling effect still exists between a conductive object such as a user and the capacitive sensing button 211. Therefore, when the conductive object such as a user moves relative to the first button portion 13, one or both of the coupling capacitance value and the coupling position of the capacitive sensing button 211 will change. This facilitates the electronic device 20 to recognize the manipulation of the capacitive sensing button 211 by the conductive object such as a user, thereby realizing the second function of the electronic device 20. The first function and the second function can be two different functions of the electronic device 20, or different operations of the same function of the electronic device 20.

[0154] In some embodiments, the sensing button 211 can be a resistive sensing button 211, which can utilize the deformability of the flexible connection part 12 and the displacement of the first button part 13 to transmit the external pressing operation to the resistive sensing button 211, and realize the control of the electronic device 20 through the pressing operation; different functions of the electronic device 20 can be controlled by different parameters such as different pressing durations.

[0155] In some embodiments, the multiple function keys 21 of the electronic device 20 may be implemented by a combination of capacitive sensing buttons 211 , resistive sensing buttons 211 , and the like.

[0156] In some embodiments, as Figure 3 As shown, the electronic device 20 includes a mobile phone, the sensing button 211 includes a shooting button 212, the protective shell 10 is provided with a side wall 113 for being arranged around the side of the mobile phone, the first button part 13 is provided on the side wall 113, and the shooting button 212 is located on the inner side of the first button part 13.

[0157] In one application scenario, the display surface of the mobile phone is defined as the front surface. When the display surface faces the user, the side facing away from the user is the back surface; the bottom wall 114 of the protective shell 10 is set corresponding to the back surface of the mobile phone; the first button part 13 is set corresponding to the shooting button 212 on the mobile phone, so that the shooting button 212 can be operated through the first button part 13.

[0158] In one application scenario, in order to improve the convenience of mobile phone operation, the function key 21 of the mobile phone is usually set on the right side of the mobile phone (in the default display mode of the mobile phone), and the first button part 13 on the protective shell 10 is set on the right wall of the protective shell 10 to correspond to the function key 21 of the mobile phone. Among them, the function key 21 includes a sensor button 211, and the sensor button 211 includes a shooting key 212 for realizing the camera function of the mobile phone. The shooting key 212 is electrically connected to the main control of the electronic device 20, such as a microprocessor unit. The shooting key 212 can convert the pressing operation, touch operation, etc. of the shooting key 212 by the user into an electrical signal and transmit it to the microprocessor unit, so that the microprocessor unit controls the camera component and other related functional components of the electronic device 20 to achieve at least one of the functions such as camera opening and closing, focus adjustment, shooting, video recording, etc.

[0159] In some embodiments, the first button portion 13 can also be set to correspond to other function keys 21 of the electronic device 20. The function key 21 can be a sensing button 211 or a press button. The function key 21 can also realize functions such as power on and off, volume adjustment, and screenshot.

[0160] In some embodiments, as Figure 11 As shown, the thickness t of the first button portion 13 is 0.1 mm to 1.2 mm.

[0161] Among them, the thickness t of the first button part 13 is less than or equal to 1.2 mm. On the one hand, the space of the opening 101 of the protective shell is limited. The thinner the thickness of the first button part 13, relatively speaking, the space available for the displacement of the first button part 13 will increase accordingly, which is conducive to the effective transmission of the pressing operation through the first button part 13; the thinner the thickness of the first button part 13, the lower the overall resistance of the first button part 13, the lower the operating distance between the user and the electronic device 20, and the interference of the first button part 13 of the protective shell on the user's operation of the electronic device 20, thereby improving the user's control sensitivity and reliability of the electronic device 20; on the other hand, the thickness t of the first button part 13 is greater than or equal to 0.1 mm, which can improve the protection ability of the first button part 13 to the function key 21, while also increasing the service life of the first button part 13 and reducing the risk of the first button part 13 breaking during operation.

[0162] In some embodiments, the specific thickness t of the first button portion 13 can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, etc.

[0163] The first button portion 13 is attached to the surface of the sensing button 211 of the electronic device 20 ; the effective use thickness range of the first button portion 13 can be limited, so that the user can conveniently operate the sensing button 211 of the electronic device 20 through the protective shell 10 .

[0164] In some embodiments, as Figure 2 、 Figure 3 As shown, the shell body 11 is formed with a side wall 113 and a bottom wall 114. The side wall 113 is arranged on the outer periphery of the bottom wall 114 to form a accommodating cavity 110 together with the bottom wall 114. The accommodating cavity 110 is configured to accommodate the electronic device 20; wherein the opening 101 is located on the side wall 113 or the bottom wall 114.

[0165] When the electronic device 20 is assembled with the protective case 10 , the back surface of the electronic device 20 abuts against the bottom wall 114 of the case body 11 , and the side surface of the electronic device 20 abuts against the side wall 113 of the case body 11 .

[0166] In an application scenario, the opening 101 is disposed on the side wall 113 , at least one function key 21 of the electronic device 20 is disposed on a side surface, and the first button portion 13 is disposed at the opening 101 .

[0167] In one application scenario (not shown), the opening 101 is set on the bottom wall 114, at least one function key 21 of the electronic device 20 is set on the back, and the first button portion 13 is set at the opening 101, so that the user can directly press the first button portion 13 at the opening 101 on the bottom wall 114 of the shell body 11 to realize the control of the function key 21.

[0168] In some embodiments, as Figure 12 As shown, Figure 12 1 is a structural diagram of another embodiment of the shell body of the present application, wherein the opening 101 is located on the side wall 113 , and the opening 101 passes through the side of the side wall 113 away from the bottom wall 114 .

[0169] The opening 101 is an open opening 101. For example, in one application scenario, the side wall 113 of the shell body 11 has a first side connected to the bottom wall 114 of the shell body 11 and a second side facing away from the bottom wall 114 of the shell body 11. The opening 101 is provided on the side wall 113, and the opening 101 passes through the second side of the side wall 113 of the shell body 11 to form the open opening 101, so that a notch is formed at the edge of the side wall 113 of the shell body 11.

[0170] In some embodiments, as Figure 2 As shown, the opening 101 is located in the middle region of the side wall 113 , such that the side wall 113 surrounds the opening 101 .

[0171] The opening 101 is a closed opening 101. The opening 101 is surrounded by the shell body 11 with greater rigidity, which can increase the connection area between the flexible connection portion 12 and the shell body 11, improve the connection stability between the flexible connection portion 12 and the shell body 11, and further improve the connection stability between the first button portion 13 and the shell body 11.

[0172] In some embodiments, when the electronic device 20 is assembled in the protective case 10 , the projection of the first button portion 13 toward the electronic device 20 covers the function key 21 of the electronic device 20 and at least a portion of the peripheral area of ​​the function key 21 .

[0173] In order to further improve the user's keystroke experience, in some embodiments, such as Figure 13 As shown, Figure 13 This is a structural diagram of an embodiment of the first button portion of the present application. The first button portion 13 includes a button body 131 and an elastic body 132 arranged around the outer periphery of the button body 131; wherein the elasticity of the button body 131 is greater than the elasticity of the elastic body 132, so that the elastic body 132 increases the rebound force on the button body 131, so that the pressing rebound feedback of the first button portion 13 is clearer.

[0174] Among them, in one application scenario, the elastomer 132 fully surrounds the first button part 13, thereby improving the overall stability and durability of the button; in another application scenario (not shown), the elastomer 132 partially surrounds the first button part 13, such as semi-enclosed surround, intermittent surround, etc.

[0175] The beneficial effect of the above arrangement is that the combined design of the button body 131 and the elastic body 132 can improve the resilience of the first button portion 13 when pressed, thereby improving the user's button touch feeling.

[0176] In other embodiments, the first button portion 13 includes a button body 131 and an elastomer 132 arranged on the button body 131. When the protective shell 10 and the electronic device 20 are assembled, the elastomer 132 is located on the side of the button body 131 close to the electronic device 20, which can improve the rebound effect of the first button portion 13 when being pressed.

[0177] The elastomer 132 can work together with the flexible connection part 12 to realize the press rebound function of the first button part 13. In a specific embodiment, the flexible connection part 12 connects the first button part 13 and the protective shell 10; the elastomer 132 is connected to the flexible connection part 12; further, the elastomer 132 can form a tight connection with the flexible connection part 12 through a hot pressing process.

[0178] In some embodiments, the flexible connection portion 12 may not exist, and the elastic body 132 is connected between the first button portion 13 and the shell body 11 to achieve the pressing rebound function of the first button portion 13.

[0179] In some embodiments, as Figure 14 As shown, Figure 14 1 is a schematic structural diagram of an embodiment of a key body of the present application. The key body 131 includes a third flexible layer 303 , a fiber layer 42 and a fourth flexible layer 304 stacked in sequence along the thickness direction z.

[0180] Specifically, along the thickness direction z of the shell body 11, the third flexible layer 303, the fiber layer 42, and the fourth flexible layer 304 are stacked in sequence. This stacked structure can improve the structural strength of the key body, stabilize the fiber layer 42, prevent deformation of the fiber layer 42, and prevent the fiber bundles woven to form the fiber layer 42 from loosening and spreading. For example, in one application scenario, the third flexible layer 303 covers one side of the fiber layer 42, and the fourth flexible layer 304 covers the other side of the fiber layer 42. That is, the projections of the third and fourth flexible layers 303 and 304 along the thickness direction z of the shell body 11 cover the fiber layer 42, thereby improving the positioning effect.

[0181] It should be noted that the size relationship between the third flexible layer 303, the fiber layer 42, and the fourth flexible layer 304 is not limited. In one application scenario, the projections of the third flexible layer 303, the fiber layer 42, and the fourth flexible layer 304 along the thickness direction z of the shell body 11 completely overlap and have the same size. In other application scenarios (not shown), the projections of the three layers can also be of different sizes. For example, the projections of the third flexible layer 303 and the fourth flexible layer 304 are both larger than the projection of the fiber layer 42 and completely cover the projection of the fiber layer 42.

[0182] Furthermore, the stiffness of the fiber layer 42 is greater than that of the third flexible layer 303 and the fourth flexible layer 304. This effectively protects the fiber layer 42 while improving the plastic deformation capability of the entire first button portion 13, thereby preventing the first button portion 13 from deforming after long-term use.

[0183] In some embodiments, the elastic body 132 includes a TPU elastic ring, the third flexible layer 303 and the fourth flexible layer 304 are both TPU films, and the fiber layer 42 is aramid fiber.

[0184] The TPU elastic ring offers excellent wear and tear resistance, maintaining excellent elasticity and stability during long-term use. Available in transparent or deep black, the TPU rubber ring is not only aesthetically pleasing but also matches the color of various electronic device casings, enhancing the overall visual effect. The high resilience of the TPU elastic ring effectively cushions keystroke pressure, extending its service life. The TPU elastic ring is adaptable to various environments and resists aging. Furthermore, the lightweight nature of the TPU material reduces device burden and enhances portability.

[0185] It is understandable that the elastic body 132 may also be formed of other types of highly elastic polymer materials in the prior art, such as silicone or rubber.

[0186] The third flexible layer 303 and the fourth flexible layer 304 are both made of TPU film. TPU film has excellent properties such as high transparency, easy molding, a high melting point, and good connectivity with other film layers. This reduces molding complexity, improves reliability and aesthetics, and enhances the visibility and quality of the fiber layer 42. Therefore, by choosing TPU film as the third and fourth flexible layers 303 and 304, the appearance of the button body 131 can be improved simply by modifying the color and appearance of the fiber layer 42, thereby enhancing the convenience of production design.

[0187] Aramid fiber, with its high strength, high modulus, high-temperature resistance, and corrosion resistance, effectively enhances the structural strength and durability of the key body 131, ensuring stable performance even under frequent presses. Its lightweight and soft properties further optimize the key's tactile feel and rebound, enhancing the user experience.

[0188] In some embodiments, the fiber layer 42 can increase the flexibility of the button body 131 and improve its fit with the buttons on the electronic device 20. The fiber layer 42 includes, but is not limited to, aramid fibers, such as dry aramid fibers or aramid fibers impregnated with thermoplastic resin, or other types of fiber materials known in the art.

[0189] In some embodiments, the fiber layer 42 includes a composite layer of aramid fiber and TPU. Aramid fiber pre-impregnated with thermoplastic resin (such as polyurethane) is used as the fiber layer 42 after molding, or aramid cloth fiber and TPU are stacked as the fiber layer 42.

[0190] The fiber layer 42 may also be pre-impregnated with epoxy resin. Pre-impregnation of the aramid fiber layer with epoxy resin reduces the material's flexibility and improves its physical properties, such as stiffness, wear resistance, and impact resistance. The fiber layer may also be pre-impregnated with epoxy resin to maintain its softness. All of the above treatment methods fall within the scope of the present invention.

[0191] In order to improve the operational sensitivity of a conductive object such as a user when operating the sensing button 211 of the electronic device 20 through the first button portion 13, the first button portion 13 may be improved as follows. Figure 15 As shown, Figure 15 This is a structural diagram of another embodiment of the protective shell partial structure of the present application. The first button portion 13 includes a conductive layer 50 , the outer side of the conductive layer 50 is covered by the flexible connecting portion 12 , and the conductive layer 50 is at least located at the opening 101 .

[0192] It should be noted that, in the present application, the inner side and inner surface of the first button portion 13 and the related structure of the first button portion 13 refer to the side close to the electronic device 20 when the protective shell 10 is equipped with the electronic device 20, and the outer side and outer surface of the first button portion 13 and the related structure of the first button portion 13 refer to the side away from the electronic device 20 and close to the user or other conductive body when the protective shell 10 is equipped with the electronic device 20.

[0193] The conductive layer 50 is a layered conductive structure, which can be a single-layer structure or a multi-layer composite structure. It is mainly used to provide electrical conductivity to form a coupling capacitor between the user's finger and the sensing button 211.

[0194] In the assembled state of the protective case 10 and the electronic device 20, the conductive layer 50 is arranged close to the electronic device 20, and the outer side of the conductive layer 50 is covered by the flexible connection part 12. The outer side of the conductive layer 50 is covered by the flexible connection part 12, which means that the projection of the flexible connection part 12 toward the electronic device 20 along the thickness direction z of the shell body 11 completely covers the conductive layer 50. In one application scenario, when a conductive object such as a user operates the sensing button 211 of the electronic device 20 through the first button part 13, the conductive object and the conductive layer 50 are separated by the flexible connection part 12, and coupling capacitance can be formed between the conductive object and the conductive layer 50, and between the conductive layer and the sensing button 211 of the electronic device 20, thereby forming a series capacitance to realize capacitive sensing. Furthermore, the conductive layer 50 is provided on the side of the flexible connection part 12 facing away from the conductive object and close to the sensing button 211. The proximity of the conductive object to the sensing button 211 can increase the conductivity of the inner side of the first button part 13 and improve the user's operation sensitivity to the sensing button 211.

[0195] In some embodiments, as Figure 15 As shown, the first button portion 13 further includes a first body layer 61 . The first body layer 61 is disposed outside the conductive layer 50 , and an outer side surface of the first body layer 61 is covered by the flexible connection portion 12 .

[0196] The first button portion 13 includes at least a first body layer 61 and a conductive layer 50. When the protective case 10 and the electronic device 20 are assembled, the conductive layer 50 is positioned adjacent to the electronic device 20. The first body layer 61 is disposed on the outer side of the conductive layer 50, and the outer side of the first body layer 61 is further covered by the flexible connection portion 12. In one application scenario, the projection of the flexible connection portion 12 along the thickness direction z of the case body 11 toward the electronic device 20 completely covers the first body layer 61. The first body layer 61 can be made of a wear-resistant material such as aramid fiber or aramid fiber impregnated with thermoplastic resin.

[0197] The first body layer 61 is arranged between the flexible connection part 12 and the conductive layer 50. The first body layer 61 can protect the conductive layer 50. In addition, adding the first body layer 61 can increase the structural strength of the first button part 13 and prevent the conductive layer 50 from being worn or damaged due to long-term use.

[0198] In some applications, the outer side of the conductive layer 50 can be further covered by the first body layer 61. That is, the projection of the first body layer 61 along the thickness direction z of the housing body 11 toward the electronic device 20 completely covers the conductive layer 50. This configuration can further enhance the protective effect of the first body layer 61 on the conductive layer 50. Furthermore, when the flexible connection portion 12 is made of a transparent material, the first body layer 61 can visually conceal the conductive layer 50. Improving the first body layer 61 can improve the appearance of the first button portion 13, thereby enhancing the convenience of production design.

[0199] In some embodiments, the flexible connection portion 12 may not cover the first body layer 61 , but may be connected to the first body layer 61 .

[0200] In some embodiments, as Figure 16 As shown, Figure 16 3 is a schematic structural diagram of an embodiment of the first body layer of the present application. The first body layer 61 includes a third flexible layer 303, a fiber layer 42 and a fourth flexible layer 304 stacked in sequence along the thickness direction z.

[0201] Specifically, in the thickness direction z of the shell body 11, the third flexible layer 303, the fiber layer 42, and the fourth flexible layer 304 are stacked in sequence. This stacked structure can improve the structural strength of the first body layer 61, stabilize the fiber layer 42, and prevent deformation and loosening of the fiber layer 42. For example, in one application scenario, the third flexible layer 303 covers one side of the fiber layer 42, and the fourth flexible layer 304 covers the other side of the fiber layer 42. That is, the projections of the third and fourth flexible layers 303 and 304 along the thickness direction z of the shell body 11 cover the fiber layer 42, thereby improving the positioning effect.

[0202] It should be noted that the size relationship between the third flexible layer 303, the fiber layer 42, and the fourth flexible layer 304 is not limited. In one application scenario, the projections of the third flexible layer 303, the fiber layer 42, and the fourth flexible layer 304 along the thickness direction z of the shell body 11 completely overlap and have the same size. In other application scenarios (not shown), the projections of the three layers can also be of different sizes. For example, the projections of the third flexible layer 303 and the fourth flexible layer 304 are both larger than the projection of the fiber layer 42 and completely cover the projection of the fiber layer 41.

[0203] In some embodiments, the third flexible layer 303 and the fourth flexible layer 304 are both TPU film layers, and the fiber layer 42 is aramid fiber. The fiber layer 42 can also be other types of fiber materials known in the prior art.

[0204] The third flexible layer 303 and the fourth flexible layer 304 are both second TPU film layers. The specific implementation and working principle of the second TPU film layer can refer to the first TPU film layer and will not be repeated here.

[0205] In one application scenario, aramid fiber, with its high strength, high modulus, high temperature resistance, and corrosion resistance, can effectively enhance the structural strength and durability of the key body 131, ensuring stable performance even under frequent pressing. Its lightweight and soft properties can further optimize the key's tactile feel and rebound effect, enhancing the user experience.

[0206] In order to improve the operational sensitivity and operational experience of a user or other conductive body when operating the sensing button 211 of the electronic device 20 through the first button portion 13 , the conductive layer 50 of the first button portion 13 may be improved. In some embodiments, the conductive layer 50 includes a conductive film layer 51 .

[0207] The conductive film layer 51 is a thin layer of conductive material. It is relatively thin and reduces the physical barrier between the user's finger and the sensor button 211 of the electronic device 20, making the feedback and tactile sensation of pressing or sliding the first button portion 13 more intuitive and sensitive. Furthermore, the conductive film layer 51 has a film-like flexibility that allows it to more closely conform to the deformation of the flexible connection portion when the user slides or presses, avoiding a stiff feel or delayed feedback caused by excessive rigidity.

[0208] The conductive film layer 51 can improve the tactile feeling of the user when pressing or sliding the first button portion 13 .

[0209] In some embodiments, the conductivity of the conductive film layer 51 is 10^6Ω to 10^12Ω.

[0210] Higher conductivity can affect the user's touch accuracy. If the conductivity is too low, the sensitivity of the sliding operation can be affected when the user slides on the first button portion 13 to control the sensor button 211 of the electronic device 20. Therefore, setting the conductivity to be greater than or equal to 10^6Ω and less than or equal to 10^12Ω can improve touch accuracy and sliding sensitivity. For example, the conductivity can be set to 10^6Ω, 10^7Ω, 10^8Ω, 10^9Ω, 10^10Ω, 10^11Ω, or 10^12Ω.

[0211] In some embodiments, the conductive film layer 51 is a TPU conductive film layer 51. The TPU conductive film layer is a composite of TPU material and conductive fillers (such as conductive carbon nanotubes, conductive graphene, and conductive silver nanowires). The TPU conductive film layer 51 has excellent conductivity, wear resistance, flexibility, hydrolysis resistance, and weather resistance, as well as good processability and environmental friendliness. It maintains stable performance in a variety of environments and is easy to manufacture and process.

[0212] In order to improve the operational sensitivity and operational experience of a user or other conductive body when operating the sensing button 211 of the electronic device 20 through the first button portion 13, the first button portion 13 and the flexible connection portion 12 may be improved as follows. In some embodiments, the conductive layer 50 includes a conductive film layer 51; Figure 17 As shown, Figure 17 This is a schematic diagram of another embodiment of the protective case structure of the present application. The flexible connection portion 12 has a two-layer structure, including a first flexible layer 301 and a second flexible layer 302. The first body layer 61 includes a third flexible layer 303 and a fiber layer 42. Along the thickness direction z, the first flexible layer 301, the third flexible layer 303, the fiber layer 42, the conductive film layer 51, and the second flexible layer 302 are stacked in sequence, with the first flexible layer 301 covering the outside of the third flexible layer 303, and the second flexible layer 302 covering the inside of the conductive film layer 51.

[0213] This stacked arrangement can further improve the structural strength of the first button portion 13 ; and the arrangement of the conductive film layer 51 can enhance the button response speed and tactile feel.

[0214] Among them, the first flexible layer 301 is arranged to cover the outer side of the third flexible layer 303, and the second flexible layer 302 is arranged to cover the inner side of the conductive film layer 51. That is, the projections of the first flexible layer 301 and the second flexible layer 302 along the thickness direction z of the shell body 11 completely cover the first body layer 61 and the conductive layer 50. This can improve the overall protection of the flexible connection part 12 (that is, the first flexible layer 301 and the second flexible layer 302) on the first button part 13 (that is, the first body layer 61 and the conductive layer 50), and improve the position stability of the first button part 13.

[0215] It should be noted that the size relationship between the third flexible layer 303, the fiber layer 42, and the conductive layer 50 is not limited. In one application scenario, the projections of the third flexible layer 303, the fiber layer 42, and the conductive layer 50 along the thickness direction z of the shell body 11 completely overlap and have the same size. In other application scenarios (not shown), the projections of the three layers can also be of different sizes. For example, the projections of the third flexible layer 303 and the conductive layer 50 are both larger than the projection of the fiber layer 42, and completely cover the projection of the fiber layer 42.

[0216] In some embodiments, as Figure 17 As shown, the first body layer 61 further includes a fourth flexible layer 304 , which is laminated between the conductive film layer 51 and the fiber layer 42 .

[0217] By adding the fourth flexible layer 304, the fiber layer 42 can be fixed by the fourth flexible layer 304 and the third flexible layer 303. During the processing, the hot pressing parameters for combining the conductive film layer 51 with the fiber layer 42 are different from the hot pressing parameters for combining the fiber layer 42 with the fourth flexible layer 304 or the third flexible layer 303. The fourth flexible layer 304, the fiber layer 42, and the third flexible layer 303 are first formed by hot pressing and laminating; then the conductive film layer 51 is attached.

[0218] This stacked arrangement can further improve the structural strength of the first button portion 13 ; and the arrangement of the conductive film layer 51 can enhance the button response speed and tactile feel.

[0219] In one application scenario, the fourth flexible layer 304 is laminated between the conductive film layer 51 and the fiber layer 42 , and the projection of the fourth flexible layer 304 along the thickness direction z of the shell body 11 completely covers the fiber layer 42 , which can further improve the structural stability of the first body layer 61 .

[0220] In order to improve the operational sensitivity and operational experience of a user or other conductive body when operating the sensing button 211 of the electronic device 20 through the first button portion 13, the first button portion 13 and the flexible connecting portion 12 may be improved as follows. Figure 18 As shown, Figure 18 This is a structural schematic diagram of another embodiment of the protective shell partial structure of the present application. The conductive layer 50 includes a conductive film layer 51; the first body layer 61 includes a third flexible layer 303, a fiber layer 42 and a fourth flexible layer 304 stacked in sequence along the thickness direction z; the flexible connection portion 12 is a single-layer structure, including a first flexible layer 301. Along the thickness direction z, the first flexible layer 301, the third flexible layer 303, the fiber layer 42, the fourth flexible layer 304, and the conductive film layer 51 are stacked in sequence. The first flexible layer 301 covers the outside of the third flexible layer 303, and the conductive film layer 51 covers the inside of the fourth flexible layer 304, and extends to the peripheral area of ​​the opening 101 on the shell body 11.

[0221] The first flexible layer 301 covers the outside of the third flexible layer 303, and the conductive film layer 51 covers the inside of the fourth flexible layer 304. This means that the projection of the first flexible layer 301 along the thickness direction z of the shell body 11 covers the third flexible layer 303, and the projection of the conductive film layer 51 along the thickness direction z of the shell body 11 covers the fourth flexible layer 304. The flexible connection portion 12 (i.e., the first flexible layer 301) and the conductive layer 50 can protect and position the first body layer 61.

[0222] Furthermore, the conductive film layer 51 extends to the peripheral area of ​​the opening 101 on the shell body 11, which can connect the conductive film layer 51 with the peripheral area of ​​the opening 101, thereby improving the positional stability of the conductive film layer 51, and the first body layer 61 can be further connected to the peripheral area of ​​the opening 101 through the conductive film layer 51, thereby improving the positional stability and reliability of the first body layer 61, and reducing the risk of movement of the conductive film layer 51 during the molding process, thereby improving the molding efficiency and the reliability of the protective shell 10 after molding.

[0223] In other embodiments, when the conductive layer 50 is other structures such as a circuit board, a structural layout similar to the above-mentioned conductive film layer 51 can also be used to realize the stacking arrangement of the first main layer 61, the flexible connection part 12, and the conductive layer 50, so as to achieve improvements to the first button part 13 and the flexible connection part 12.

[0224] In some embodiments, the conductive layer 50 may include a circuit board, wherein the circuit board may include a PCB (Printed Circuit Board) or an FPC (Flexible Printed Circuit).

[0225] The advantage of the circuit board is that its structural design enables it to accurately identify the touch location of a conductive object, such as a user, on the first button portion 13, further improving touch accuracy. For example, in one application scenario, the circuit board can be designed with a capacitor array or a capacitive sensing area to accurately identify the touch location by sensing changes in the electric field when a user touches it. The circuit board also performs capacitive sensing between the circuit board and the function key 21 of the electronic device 20, thereby improving touch accuracy.

[0226] In some embodiments, as Figure 19 As shown, the conductive layer 50 includes a plurality of conductive regions 521 that are insulated and arranged along a first direction x; wherein the first direction x is the length direction of the first button portion 13 .

[0227] The length direction of the first button portion 13 refers to the direction in which the long side of the first button portion 13 extends within a plane perpendicular to the thickness direction z of the housing body 11. A user can slide and touch the first button portion 13 along its length direction. The specific insulation layout design can precisely enhance the conductive layer 50's ability to accurately detect and identify the specific touch location of a user or other conductive object, thereby improving the user's control accuracy when controlling the sensor button 211 of the electronic device 20 via the first button portion 13.

[0228] The conductive area 521 is segmented and arranged inside the first button portion 13. After the protective case 10 is equipped with the electronic device 20, the first button portion 13 is close to or in contact with the sensing button 211. When a user or other conductive object touches the first button portion 13, the conductive area 521 will form coupling capacitances with the conductive object (human body) and with the sensing button 211 respectively. These two coupling capacitances can be considered to be arranged in series, thereby forming a series capacitance between the conductive object and the sensing button 211. When the conductive object moves along the first direction x, it will sequentially form series capacitances with the multiple segmented conductive areas 521. In actual use, when the user slides his finger, the finger (or the conductive object) forms a series capacitance with the conductive area 521 at the corresponding position. The chip accurately identifies and locates the position of the finger by sensing the capacitance change at the corresponding position.

[0229] Furthermore, the provision of the flexible connection portion 12 facilitates the transmission of the pressure of the conductor to the sensing button 211 , thereby achieving the pressing operation on the sensing button 211 .

[0230] For example, in one application scenario, multiple conductive regions 521 are spaced apart to achieve insulation. In other application scenarios, an insulating strip can be provided between two adjacent conductive regions 521. For example, a high-impedance insulating ink (such as UV insulating ink, epoxy resin, or silicone coating) can be provided to form an insulating strip, effectively improving the accuracy of touch signal recognition during use. In other application scenarios, insulation can also be achieved through other methods.

[0231] In some embodiments, as Figure 19 As shown, the conductive layer 50 is a multi-layer structure, and the conductive layer 50 includes a first conductive layer 522, an insulating layer 524 and a second conductive layer 523 stacked along the thickness direction z. The first conductive layer 522 and the second conductive layer 523 are electrically connected through a conductive member (not shown) provided in a via 525 of the insulating layer 524.

[0232] The first conductive layer 522, the insulating layer 524, and the second conductive layer 523 are stacked in sequence. The first conductive layer 522 and the second conductive layer 523 can be electrically connected through the vias 525 in the insulating layer 524, eliminating the need for additional wiring, resulting in a simple structure and reducing the size of the circuit board.

[0233] The first conductive layer 522 and the second conductive layer 523 include a plurality of conductive regions 521 insulated along the first direction x, and a conductive region 521 in the first conductive layer 522 is electrically connected to a corresponding conductive region 521 in the second conductive layer 523 through a conductive member in a via 525 .

[0234] In some application scenarios, see Figure 19The multiple conductive regions 521 of the first conductive layer 522 and the second conductive layer 523 are correspondingly arranged along the thickness direction z of the shell body 11. For example, the first conductive layer 522 includes multiple conductive regions 521 arranged at intervals, and the second conductive layer 523 includes multiple conductive regions 521 arranged at intervals. The projections of the multiple conductive regions 521 of the second conductive layer 523 and the multiple conductive regions 521 of the first conductive layer 522 along the thickness direction z of the shell body 11 are arranged one by one and overlapping.

[0235] In some applications, when fabricating the first conductive layer 522 and the second conductive layer 523, photolithography or chemical etching processes can be used to etch spacing regions into the conductive layers. This ensures that each conductive region 521 is insulated from each other, and that the conductive regions of the first conductive layer 522 and the conductive regions of the second conductive layer 523 correspond to each other in a one-to-one, overlapping arrangement, as projected along the thickness direction z. This allows for precise control of the shape and spacing of the conductive regions 521, optimizing touch signal recognition.

[0236] In some embodiments, the conductive layer 50 further includes a second insulating layer 5242 disposed on a side of the first conductive layer 522 facing away from the insulating layer 524, and a third insulating layer 5243 disposed on a side of the second conductive layer 523 facing away from the insulating layer 524. The second insulating layer 5242 and the third insulating layer 5243 protect the first conductive layer 522 and the second conductive layer 523, respectively, thereby enhancing the durability and stability of the conductive layer 50. This laminated design improves touch accuracy and operational reliability while maintaining a compact structure.

[0237] In some embodiments, one or more of the insulating layer 524, the second insulating layer 5242, and the third insulating layer 5243 may be a flexible insulating layer, such as a PI film, a PET film, a PEN film, etc. The first conductive layer 522 and the second conductive layer 523 may be a copper foil structure or a graphene film structure.

[0238] The insulating material may be actively filled in adjacent conductive regions 521 , or the insulating layer may fill the gaps between adjacent conductive regions 521 during the hot pressing process.

[0239] In the above embodiment, the conductive layer and the fiber layer are combined to solve the technical problem of insensitive touch caused by the fiber layer due to poor conductivity of the fiber layer.

[0240] In some embodiments, the first body layer 61 includes a hard fiber layer, and the hard fiber layer may be fibers impregnated with a thermosetting resin.

[0241] In one application scenario, the hard fiber layer can be formed by an aramid fiber material impregnated with epoxy resin after molding, which can improve the structural stability of the first body layer 61. This structure does not require an additional shaping film layer and is not prone to loosening or deformation.

[0242] In some embodiments, the hard fiber layer comprises a composite layer of aramid fibers and a thermosetting resin. Aramid fibers pre-impregnated with a thermosetting resin (e.g., epoxy resin) are used as the hard fiber layer after molding. In other embodiments, the hard fiber layer can be made of man-made fibers such as carbon fiber and glass fiber, or metal, rigid plastic, or inorganic materials such as silicate.

[0243] In some embodiments, as Figure 20 As shown, Figure 20 This is a structural schematic diagram of another embodiment of the protective shell partial structure of the present application. The first main body layer 61 includes a hard fiber layer, and the flexible connection part 12 is a double-layer structure, including a first flexible layer 301 and a second flexible layer 302; along the thickness direction z, the first flexible layer 301, the hard fiber layer, the conductive layer 50 and the second flexible layer 302 are stacked in sequence, the first flexible layer 301 covers the outside of the hard fiber layer, and the second flexible layer 302 covers the inside of the conductive layer 50.

[0244] The first flexible layer 301 covers the outside of the hard fiber layer, and the second flexible layer 302 covers the inside of the conductive layer 50, thereby protecting the hard fiber layer and the conductive layer 50 and improving structural strength. This covering design also increases the connection area between the first and second flexible layers 301, 302, the hard fiber layer, and the conductive layer 50, improving connection stability and, in turn, enhancing the positional stability of the first button portion 13 when pressed. Optionally, the hard fiber layer is formed by impregnating aramid fiber with epoxy resin.

[0245] In other embodiments, when the conductive layer 50 is other structures such as a conductive film layer 51 , a similar structural layout may be used to achieve a stacked arrangement of the hard fiber layer, the first flexible layer 301 , the second flexible layer 302 , and the conductive layer 50 .

[0246] In other embodiments, when the first body layer 61 includes a fiber layer, a structural layout similar to the above-mentioned hard fiber layer can also be used to achieve a stacked arrangement of the fiber layer, the fourth flexible layer 304 , the first flexible layer 301 , and the conductive layer 50 .

[0247] The second flexible layer 302 inside the conductive layer 50 can also improve or reduce marks left on the conductive layer 50 due to long-term contact between the conductive layer 50 and the function keys 21 of the electronic device 20 .

[0248] In some embodiments, as Figure 21As shown, the first button portion 13 includes a fiber layer 42, and the flexible connection portion 12 has a double-layer structure, including a first flexible layer 301 and a second flexible layer 302. Along the thickness direction z, the first flexible layer 301, the fiber layer 42, and the second flexible layer 302 are stacked in sequence, and along the thickness direction z, the projection of the first flexible layer 301 and the projection of the second flexible layer 302 cover the opening 101 and the peripheral area of ​​the opening 101.

[0249] In some embodiments, the projection of the first flexible layer 301 and the projection of the second flexible layer 302 both cover the first opening 1011 and its peripheral area, and the second opening 1012 and its peripheral area.

[0250] Among them, the projection of the first flexible layer 301 and the projection of the second flexible layer 302 cover the opening 101 and the peripheral area of ​​the opening 101, which can realize the connection and fixation of the first flexible layer 301, the second flexible layer 302 and the peripheral area of ​​the opening 101; and the first flexible layer 301, the fiber layer 42, and the second flexible layer 302 are stacked in sequence, and the fiber layer 42 can be positioned by the first flexible layer 301 and the second flexible layer 302, thereby reducing the risk of positional displacement of the fiber layer 42 during the molding process, and the first flexible layer 301 and the second flexible layer 302 also have a protective effect on the fiber layer 42.

[0251] In one application scenario, the projections of the first flexible layer 301 and the second flexible layer 302 along the thickness direction z of the shell body 11 both cover the fiber layer 42 to further improve the protection and positioning effects of the fiber layer 42 .

[0252] In some embodiments, as Figure 22 As shown, Figure 22 This is a structural schematic diagram of another embodiment of the protective shell partial structure of the present application. The fiber layer 42 is arranged in the first opening 1011. Along the thickness direction z, the first flexible layer 301 is located on the side of the first supporting layer 111 away from the second supporting layer 112, and the second flexible layer 302 is located between the first supporting layer 111 and the second supporting layer 112, and the first flexible layer 301 and the second flexible layer 302 both extend to the peripheral area of ​​the first opening 1011.

[0253] This arrangement can improve the positional stability of the first flexible layer 301 and the second flexible layer 302 through the first supporting layer 111 and the second supporting layer 112, thereby improving the positioning effect of the first flexible layer 301 and the second flexible layer 302 on the fiber layer 42 and reducing the risk of displacement of the first button portion 13 when being pressed.

[0254] The first flexible layer 301 and the second flexible layer 302 may also be provided in other ways. For example, in some embodiments, Figure 23 As shown, Figure 23This is a structural schematic diagram of another embodiment of the protective shell partial structure of the present application. The fiber layer 42 is arranged in the second opening 1012. Along the thickness direction z, the first flexible layer 301 is located on the side of the second supporting layer 112 away from the first supporting layer 111, and the second flexible layer 302 is located between the first supporting layer 111 and the second supporting layer 112. Along the thickness direction z, the projection of the first flexible layer 301 and the projection of the second flexible layer 302 cover the peripheral area of ​​the second opening 1012.

[0255] For example, in some embodiments, Figure 21 As shown, the first flexible layer 301 and the second flexible layer 302 are located between the first supporting layer 111 and the second supporting layer 112 .

[0256] In some embodiments, as Figure 24 As shown, Figure 24 This is a structural schematic diagram of another embodiment of the protective shell partial structure of the present application. The first button portion 13 includes two fiber layers 42. The flexible connection portion 12 has a three-layer structure, including a first flexible layer 301, a second flexible layer 302, and a fifth flexible layer 305. One fiber layer 42 is arranged in the first opening 1011, and the other fiber layer 42 is arranged in the second opening 1012. Along the thickness direction z, the first flexible layer 301, the first supporting layer 111, the second flexible layer 302, the second supporting layer 112 and the fifth flexible layer 305 are stacked in sequence, and the first flexible layer 301 and the second flexible layer 302 are both covered with a fiber layer 42 and extend to the peripheral area of ​​the first opening 1011. The second flexible layer 302 and the fifth flexible layer 305 are both covered with another fiber layer 42 and extend to the peripheral area of ​​the second opening 1012.

[0257] The fifth flexible layer 305 may be improved with reference to the second flexible layer 302 , which will not be described in detail here.

[0258] The second flexible layer 302 and the fifth flexible layer 305 position and protect one fiber layer 42, while the first flexible layer 301 and the second flexible layer 302 position and protect the other fiber layer 42. This embodiment utilizes dual body layers and dual rigid layers to form the protective case 10, thereby improving the overall rigidity of the protective case 10. Furthermore, the two fiber layers 42 are positioned within the openings 101 of the corresponding rigid layers, reducing the overall thickness. The provision of the positioning membrane reduces the risk of positional shifting of the body layer during the molding process, thereby improving molding efficiency and the reliability of the finished protective case 10.

[0259] In order to improve the operational sensitivity and operational experience of a user or other conductive body when operating the sensing button 211 of the electronic device 20 through the first button portion 13, the first button portion 13 and the flexible connecting portion 12 may be improved as follows. Figure 37As shown, the first button portion 13 includes a third flexible layer 303, a fiber layer 42 and a fourth flexible layer 304. The flexible connection portion 12 has a double-layer structure, including a first flexible layer 301 and a second flexible layer 302. Along the thickness direction z of the shell body 11, the first flexible layer 301, the third flexible layer 303, the fiber layer 42, the fourth flexible layer 304 and the second flexible layer 302 are stacked in sequence.

[0260] In this embodiment, the first button portion 13 includes a third flexible layer 303, a fiber layer 42, and a fourth flexible layer 304. This prevents the fiber layer 42 from becoming loose and deformed, facilitating processing. The first button portion 13 is integrated with the housing body 11 via the first flexible layer 301 and the second flexible layer 302, improving the positional stability of the first button portion 13. For example, the projections of the first flexible layer 301 and the second flexible layer 302 in the thickness direction of the housing body 11 cover the opening 101 and the peripheral area of ​​the opening 101, thereby enhancing the positioning of the first button portion 13.

[0261] In order to further improve the multi-scenario adaptability of the protective case 10 and enhance the user experience, in some embodiments, such as Figure 25 As shown, Figure 25 This is a structural diagram of another embodiment of the protective shell partial structure of the present application. The protective shell 10 also includes a second button portion 14. The second button portion 14 is arranged on the inner side of the first button portion 13 and is located at the opening 101. The second button portion 14 is used to communicate data with the electronic device 20 assembled on the protective shell 10 when triggered by the first button portion 13.

[0262] In the assembled state of the protective shell 10 and the electronic device 20 , the second button portion 14 is arranged inside the first button portion 13 , that is, the second button portion 14 is arranged on a side of the first button portion 13 close to the electronic device 20 .

[0263] In an application scenario, the user can trigger the second button portion 14 by pressing the first button portion 13 , and then can achieve data communication with the electronic device 20 assembled in the protective shell 10 through the button operation.

[0264] For example, in one application scenario, when a sensing area is provided on the back of the electronic device 20, the second button portion 14 is located at least at the opening 101 and can be triggered by the first button portion 13. Furthermore, the functional components of the second button portion 14 extend at least to the position corresponding to where the case body 11 abuts or is in close proximity to the sensing area of ​​the electronic device 20. When assembled, the functional components of the second button portion 14 are positioned corresponding to the position of the sensing area of ​​the electronic device 20. Therefore, by pressing the first button portion 13, the user can trigger the functional components of the second button portion 14, thereby enabling data communication with the sensing area on the back of the electronic device 20. For example, the first button portion 13 can be located on the side wall 113 of the case body 11, thereby eliminating the need for openings in the bottom wall 114 of the case body 11 to trigger the sensing area on the back of the electronic device 20. This arrangement increases the flexibility and versatility of how users can wake up or operate the electronic device 20 through the protective case 10, enhancing the user experience.

[0265] For example, in one application scenario, the protective case 10 is provided with multiple openings 101 and multiple corresponding first button portions 13, each of which corresponds to a different sensor button 211 of the electronic device 20; wherein, a corresponding second button portion 14 is provided inside at least one of the first button portions 13. This arrangement can further enhance the adaptability of the protective case 10 in multiple scenarios, and can increase the flexibility and convenience of the user in waking up or triggering the electronic device 20 through the protective case 10.

[0266] In some embodiments, the second button portion 14 includes an NFC (Near Field Communication) component.

[0267] The NFC component can realize near field communication. In this way, the user can trigger the NFC function by pressing the first button portion 13 on the protective shell 10, and can communicate with the corresponding component on the electronic device 20 through the NFC component, thereby waking up or operating the electronic device 20.

[0268] NFC is a short-range, high-frequency wireless communication technology that enables contactless interaction between devices through electromagnetic induction coupling. The NFC component can be designed as a thin sheet that fits the curved surface of the protective case 10 or miniaturized and embedded in the key area. The NFC component can be triggered by pressing a physical button or touching it.

[0269] In some embodiments, the user can trigger the NFC function by pressing the first button portion 13 on the protective shell 10, thereby enabling the NFC component to communicate with the electronic device 20, and then waking up or operating the electronic device 20. Specifically, when the user presses the button, the mechanical switch closes or the sensor detects a pressure signal, and the signal is transmitted to the microcontroller (such as MCU) in the protective shell 10, triggering the NFC function start instruction. The electronic device 20 reads the data sent by the NFC component and performs the corresponding operation. Compared with the traditional protective shell NFC component that is mostly set independently, in this embodiment, the NFC component is integrated into the button, and the NFC function (such as press to pay) can be triggered when the button is pressed, reducing additional operation steps and improving ease of use. Secondly, compared with the normally open NFC component that is continuously in a readable state, the function of the NFC component in this embodiment is controlled and activated, which can reduce the frequency of false triggering during non-active operation. At the same time, the press-type trigger mechanism provides location awareness of the NFC function through the physical touch of the button, allowing users to locate the operation area without visual confirmation, making the operation more convenient and controllable. In addition, this design makes full use of the internal space within the key, avoiding additional holes or thickening in other areas of the protective shell 10, making the overall structure of the protective shell 10 more compact.

[0270] In some embodiments, the user can trigger the NFC function by touching the first button portion 13 on the protective shell 10. Specifically, the button area (first button portion 13) of the protective shell 10 has a built-in capacitive touch sensor. When the user's finger touches the button, the sensor detects the change in capacitance and generates an electrical signal. The signal is transmitted to the MCU in the protective shell 10, triggering the preset logic (such as starting the NFC function). The electronic device 20 reads the data sent by the NFC component and performs corresponding operations (such as starting an application, connecting a device). This example does not require physical pressing, and can be triggered by a light touch, which provides a more sensitive user experience.

[0271] The second button portion 14 may also implement wireless communication functions using Bluetooth, RFID, ZIGBEE, a combination of the above technologies, or a combination of the above technologies and NFC technology.

[0272] In some embodiments, as Figure 26 、 27 As shown, Figure 26 This is a structural diagram of an embodiment of the second button portion of the present application. Figure 27 This is a schematic diagram of the exploded structure of an embodiment of the protective shell structure of the present application. The NFC component includes: an electronic trigger 141 and a functional device 142. The electronic trigger 141 is used to be electrically connected to the functional device 142. The first button part 13 conflicts with the electronic trigger 141 under the action of external force, thereby triggering the functional device 142.

[0273] In one example, the electronic trigger 141 is a triggering device that receives mechanical pressure or capacitance changes and converts them into an electrical signal. It is connected to the functional device 142 to activate the NFC function. The electronic trigger 141 can be mechanical, such as conductive rubber or metal dome. Alternatively, the electronic trigger 141 can be inductive, outputting a pressure threshold signal through a pressure-sensitive layer and signal processing circuit. Specifically, in the thickness direction z of the housing body 11, the electronic trigger 141 is positioned corresponding to the first button portion 13. Thus, by manipulating the first button portion 13, the electronic trigger 141 can be directly triggered, thereby activating the NFC function of the electronic device.

[0274] Functional device 142 is an electronic module that performs NFC functions. It initiates communication or performs a preset operation upon receiving a signal from electronic trigger 141. Functional device 142 typically includes a signal input interface for connecting to the electronic trigger, a logic control unit for determining the trigger condition, and a communication unit that sends preset data to an external card reader.

[0275] The electronic trigger 141 and the functional device 142 can be directly integrated and installed, such as soldering the electronic trigger (such as a micro switch or capacitive sensor) and the functional device on the same PCB; or designing an independent functional module and embedding it into the reserved slot of the protective shell through mechanical connection methods such as snaps / slides to facilitate subsequent maintenance and replacement. The electronic trigger 141 and the functional device 142 can also be installed in a split manner, such as placing the electronic trigger and the functional device separately and connecting them through a flexible printed circuit board (FPC) or a cable to adapt to the curved surface or moving parts of the shell; or setting magnetic contacts (such as Pogo Pins) on the trigger and the functional device to achieve physical contact and signal conduction through magnetic attraction.

[0276] In one application scenario, when the shell body 11 is formed with a side wall 113 and a bottom wall 114, and the first button portion 13 is provided on the side wall 113, the electronic trigger 141 is provided on the side wall 113 of the shell body 11 and is provided corresponding to the first button portion 13; the functional device 142 is provided on the bottom wall 114. It is understood that electronic devices usually have an NFC sensing area on the back. By providing the functional device 142 on the bottom wall 114 of the shell body 11, it can correspond to the NFC sensing area on the back of the electronic device. Therefore, the NFC sensing area on the back of the electronic device 20 can be triggered by the first button portion 13 on the side of the shell body 11, which can increase the flexibility and diversity of the user's awakening or operation of the electronic device 20 through the protective shell 10, thereby improving the user's usage experience.

[0277] In one application scenario, the electronic trigger 141 includes a circuit board and a switch element, and the functional device 142 includes an FPC coil electrically connected to the circuit board.

[0278] The circuit board can be rectangular, circular, or polygonal in shape to accommodate the internal layout of the device. It can be made of FR-4 epoxy resin substrate (a conventional PCB material) or a flexible substrate (such as polyimide, which can bend). The circuit board can have a double-layer or multi-layer wiring structure to integrate power interfaces, signal processing units (such as MCU chips), and solder pads.

[0279] The switch element can be a touch switch, a membrane switch, a pressure sensor, etc. according to the triggering method. The shape of the switch element can be a micro patch type or a cylindrical button. When the user touches the first button part, the capacitive sensor detects and outputs a signal, the NFC signal unit receives the signal and sends the preset data, and then the mobile phone receives the data and responds. In some scenarios, the user can touch the button to make NFC send a Bluetooth pairing instruction, so that the mobile phone automatically connects to other electronic devices. When the user touches the first button part, the switch is closed and the circuit is connected, so that the NFC function is activated and data is sent to the mobile phone, and the mobile phone responds after receiving the data. In some usage scenarios, the user can press the button to make NFC send pre-stored payment card information, and the mobile phone then calls up the payment interface.

[0280] In some embodiments, the protective case 10 also has a charging function. In this case, the NFC component can be used to control charging.

[0281] The electronic trigger 141 can be used to start or activate the functional device 142 . For example, the electronic trigger 141 can be a component with a piezoelectric sensing function, which can generate an electrical signal when pressed, thereby activating the functional device 142 .

[0282] The beneficial effect of the above arrangement is that the functional device 142 can be triggered with a simple button operation, which is easy to operate and provides a good user experience. Different types of functional devices 142 can be designed according to the needs of different application scenarios to improve the multi-scenario applicability of the protective case 10. For example, through the special design of the functional device, the user can trigger preset operations via NFC, such as launching applications, mini-programs, connecting to Wi-Fi, switching modes, turning on the flashlight, controlling smart home devices, etc.

[0283] In some embodiments, the functional device 142 includes a coil, which may be a PCB coil, a Litz wire coil, or an FPC coil.

[0284] The functional device 142 may be a flexible printed circuit (FPC) coil that can be connected to a circuit board. The FPC coil is thin and flexible and can be bent to fit irregular surfaces to make the overall device compact.

[0285] In some embodiments, as Figure 26 As shown, the second button portion 14 further includes a pressing portion 143 disposed between the NFC component and the first button portion 13 .

[0286] The user can press the first button portion 13 to indirectly trigger the pressing portion 143 , thereby activating the NFC component and achieving communication with the electronic device 20 .

[0287] In some embodiments, as Figure 26 、 27 As shown, the inner side wall of the shell body 11 is provided with a limiting groove 140 communicating with the opening 101 , and the electronic trigger 141 is limited to the shell body 11 by the limiting groove 140 .

[0288] Specifically, the bottom of the limiting groove 140 is provided with a through-hole that communicates with the opening 101. Therefore, pressing the first button portion 13 at the opening 101 can directly trigger the electronic trigger 141, thereby triggering the second button portion 14. Furthermore, the electronic trigger 141 is limited to the limiting groove 140, which can improve the positional stability of the electronic trigger 141, reduce device displacement caused by frequent operation, and ensure that each press can accurately trigger the functional device 142.

[0289] In some embodiments, as Figure 26 As shown, the protective shell 10 further includes a packaging cover 15 , which is connected to the side of the electronic trigger 141 facing away from the first button portion 13 ; the packaging cover 15 is installed on the inner side wall 113 of the shell body 11 and covers the limiting groove 140 .

[0290] The packaging cover 15 is installed on the inner side wall 113 of the shell body 11 and covers the limiting groove 140 , which means that the packaging cover 15 is arranged on a side of the protective shell 10 close to the electronic device 20 .

[0291] The package cover 15 provides support for the NFC component, allowing it to stably move in the direction of pressure without deflecting in other directions. This arrangement effectively improves the positional stability and reliability of the electronic trigger 141. Specifically, the package cover 15 effectively protects the electronic trigger 141, preventing dust and moisture from entering the retaining groove 140, ensuring that the electronic trigger 141 maintains efficient response even during long-term use.

[0292] In order to further reduce the size of the protective case 10, similar improvements may be made to the first button portion 13. For example, in some embodiments, the first button portion 13 includes an NFC component.

[0293] The working principle and specific implementation of the NFC component can be found in the above embodiments and will not be described in detail here.

[0294] In order to further improve the user's operating experience when triggering the sensing button 211 of the electronic device 20 through the first button portion 13, the first button portion 13 may be further improved. Figure 28 As shown, Figure 28 This is a structural diagram of an embodiment of the protective shell and electronic device structure of the present application. The inner surface of the first button portion 13 is flush with the inner surface of the outer peripheral area of ​​the opening 101 or bulges inward to form a first bulge 134.

[0295] The inner surface of the first button portion 13 refers to the side of the first button portion 13 close to the electronic device 20, and the inner surface of the outer peripheral area of ​​the opening 101 refers to the side of the outer peripheral area of ​​the opening 101 close to the electronic device 20. The inner surface of the first button portion 13 is flush with the inner surface of the outer peripheral area of ​​the opening 101, which facilitates the user to assemble the protective case 10 onto the electronic device 20. The inner surface of the first button portion 13 is raised inward relative to the inner surface of the outer peripheral area of ​​the opening 101, which means that in the assembled state, the inner surface of the first button portion 13 protrudes relative to the inner surface of the outer peripheral area of ​​the opening 101 toward the side of the electronic device 20 to form a first raised portion 134. The design of the first raised portion 134 can reduce the operation process when the user presses the button, improve trigger sensitivity, and optimize the user experience.

[0296] In one application scenario, the sensor button 211 of the electronic device 20 is located on the side surface, and in the assembled state, the position of the sensor button 211 corresponds to the position of the first button portion 13 on the side wall 113 of the protective case 10. When the sensor button 211 of the electronic device 20 is recessed in the side surface of the electronic device 20, the inner surface of the first button portion 13 is configured to convex inward to form a first raised portion 134 that matches the concave shape of the sensor button 211. This allows the user to more accurately correspond to the concave position of the sensor button 211 when pressing the first button portion 13, reducing the probability of accidental touches, shortening the keystroke process, and improving operational convenience.

[0297] In some embodiments, the protrusion height H1 of the first protrusion 134 is 0.1 mm to 0.5 mm.

[0298] If the raised height is too high, the key feedback may be too strong, affecting the operating feel; if the raised height is too low, it may not effectively reduce the keystroke process. Therefore, choosing a reasonable raised height, such as 0.1mm, 0.2mm, 0.3mm, 0.4mm, or 0.5mm, can ensure trigger sensitivity and optimize the user experience.

[0299] In some embodiments, the protrusion height H1 of the first protrusion 134 is 0.2 mm to 0.3 mm.

[0300] The protrusion height H1 of the first protrusion 134 is selected within this range, which can further improve the operation accuracy and the user's key pressing experience.

[0301] In some embodiments, as Figure 29 As shown, Figure 29 This is a schematic diagram of the cross-sectional structure of an embodiment of the partial structure of the protective shell of the present application after the molding process. When the protective shell 10 is assembled with the electronic device 20, the outer surface of the area of ​​the flexible connection part 12 corresponding to the first button part 13 bulges outward relative to the outer surfaces of other areas of the flexible connection part 12 to form a second bulge 135.

[0302] The provision of the second protrusion 135 can improve the efficiency and reliability of the recognition of the first button portion 13 , thereby improving the operating efficiency and reliability of the electronic device 20 .

[0303] In other embodiments, this can be achieved by recessing the outer surface of the area of ​​the flexible connection portion 12 corresponding to the first button portion 13 relative to the outer surfaces of other areas of the flexible connection portion 12, or by providing the outer surface of the area of ​​the flexible connection portion 12 corresponding to the first button portion 13 with a different texture, color, or reflectivity from the shell body 11. For example, the outer surface of the area of ​​the flexible connection portion 12 corresponding to the first button portion 13 can be treated with a fluorescent treatment or other surface treatment to allow the user to immediately notice the area of ​​the flexible connection portion 12 corresponding to the first button portion 13.

[0304] In other embodiments, when the flexible connection portion 12 does not cover the first button portion 13, the outer surface of the first button portion 13 can also be recessed or raised relative to the outer surface of the peripheral area of ​​the opening 101. Or it can be achieved by setting the first button portion 13 and the shell body 11 to have different textures, different colors, different reflectivity, etc. For example, the outer surface of the first button portion 13 can be subjected to surface treatment such as fluorescent treatment so that the user can notice the first button portion 13 at the first time. In a specific embodiment, a fluorescent agent is added to the material layer of the first button portion 13 to help the user better notice the existence of the first button portion 13 in a dark environment. In this case, the second raised portion 135 may not be provided, so that the outer surface of the first button portion 13 is flush with the outer surface of the peripheral area of ​​the opening 101.

[0305] In some embodiments, the raised height H2 of the second raised portion 135 is 0 to 0.5 mm. When the raised height H2 is 0, it can be understood that the second raised portion 135 is not formed, and the outer surface of the first button portion 13 is flush with the outer surface of the outer peripheral area of ​​the opening 101. For example, the raised height H2 can be 0, 0.05 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm.

[0306] In some embodiments, the protrusion height H2 of the second protrusion 135 is 0.1 mm to 0.5 mm.

[0307] The height H2 of the second raised portion 135 is selected to be within the range of 0.1mm to 0.5mm, ensuring sensitive key recognition while avoiding operational inconvenience caused by excessive protrusion. For example, the height can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, or 0.5mm to balance visual effects and operational feel, further enhancing the user experience.

[0308] In some embodiments, the outer side surface of the integrated structure of the flexible connection portion 12 and the first button portion 13 protrudes from the outer side surface of the housing body 11 by a height of 0 mm to 0.5 mm. The protrusion height can specifically be 0, 0.05 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm.

[0309] In order to further improve the position stability of the first button portion 13 and the shell body 11, in some embodiments, such as Figure 5 As shown, the protective case 10 further includes a first positioning film 316 , which is disposed on the outer side of the case body 11 and covers at least the opening 101 .

[0310] The provision of the first positioning film 316 can reduce or prevent the surface material of the case body 11 (e.g., the first supporting layer 111 and the second supporting layer 112) from contacting the first button portion 13 located within the opening 101 during the molding process of the protective case 10, thereby causing the surface of the first button portion 13 to become brittle or hard, thereby affecting the button's functionality. Therefore, this embodiment can improve the reliability of the first button portion 13 and the protective case 10.

[0311] In order to further improve the position stability of the first button portion 13 and the shell body 11, in some embodiments, such as Figure 5 As shown, the protective case 10 further includes a second positioning film 317 disposed on the inner side of the case body 11 and covering at least the opening 101 .

[0312] The provision of the second positioning film 317 can reduce or prevent the surface material of the case body 11 (e.g., the first supporting layer 111 and the second supporting layer 112) from contacting the first button portion 13 located within the opening 101 during the molding process of the protective case 10, thereby causing the surface of the first button portion 13 to become brittle or hard, thereby affecting the button's functionality. Therefore, this embodiment can improve the reliability of the first button portion 13 and the protective case 10.

[0313] In some embodiments, the first button portion 13 is provided with a first protrusion 134 and a second protrusion 135 to improve the convenience and key pressing experience of the user.

[0314] In some embodiments, the thicknesses of the first supporting layer 111 and the second supporting layer 112 may be different.

[0315] The present application further proposes a protective shell 10. In some embodiments, as Figure 30 As shown, the protective case 10 includes a case body 11, a flexible connection portion 12, and an elastic ring 16. The case body 11 has an opening 101; the elastic ring 16 is disposed at the opening 101, and the flexible connection portion 12 covers the elastic ring 16 and the opening 101. The elastic ring 16 is integrally provided with the case body 11 via the flexible connection portion 12. The rigidity of the case body 11 is greater than that of the flexible connection portion 12.

[0316] There are various ways to achieve this integration. For example, heating or pressurizing the at least two material layers causes the relevant substances to melt, flow to a specific location under pressure or a mold, and then solidify under the influence of temperature or pressure. Alternatively, the material layers can be bonded together using adhesive or other methods and then solidified. The integration mentioned here creates a whole that cannot be separated without violent intervention between the at least two material layers. This indivisible whole is also called a "one-piece whole."

[0317] In one application scenario, the protective case 10 and the electronic device 20 are in an assembled state, and the user can trigger the sensing button 211 of the electronic device 20 corresponding to the opening 101 by pressing the flexible connection part 12 at the opening 101; further, pressing the flexible connection part 12 at the opening 101 can achieve effective compression of the elastic ring 16, and then achieve rapid rebound of the flexible connection part 12 at the opening 101 when the user releases the pressure on the flexible connection part 12.

[0318] In this way, the flexible connection part 12 is provided to cover the elastic ring 16 and the opening 101, which can effectively improve the protection effect of the protective case 10 on the electronic device 20 and reduce the risk of the electronic device 20 being directly exposed to the external environment at the opening 101; further, the flexible connection part 12 is provided to cover the elastic ring 16 and the opening 101, and the flexible connection part 12 can be used to achieve the effect of setting a button on the protective case 10, which can reduce the thickness of the protective case 10; further, the flexible connection part 12 can form a flexible area at the opening 101, and the flexible area is easy to deform under the action of external force, which can reduce the difficulty of disassembly and assembly of the protective case 10 and improve the sensitivity and reliability of external operation on the electronic device 20; further, the provision of the elastic ring 16 can improve the rebound effect of the flexible connection part 12 at the opening 101, thereby improving the user's key experience.

[0319] In some embodiments, improvements to the shell body 11 may refer to the above embodiments and will not be described in detail here.

[0320] This application further proposes a method for preparing a protective shell 10. In some embodiments, Figure 31 As shown, Figure 31 1 is a flow chart of an embodiment of a method for preparing a protective shell of the present application, wherein the method includes steps S11 to S13.

[0321] Step S11: preparing a first button portion and a shell body, wherein the shell body is provided with an opening.

[0322] According to the size and shape of the electronic device 20 , the relevant material layers are cut into a shell body 11 that matches the shape and size of the electronic device 20 , and an opening 101 of corresponding size is set on the bottom wall 114 or side wall 113 of the shell body 11 according to the application scenario.

[0323] With reference to the specific structure of the first button portion 13 in the above embodiment, the first button portion 13 is prepared by bonding or hot pressing with corresponding materials.

[0324] Step S12: performing a hot pressing process on the flexible connection portion and the first button portion to obtain a button body.

[0325] In this way, the flexible connection portion 12 and the first button portion 13 are fixedly connected.

[0326] Step S13: The shell body and the key body are stacked to integrally set the key body and the shell body through the flexible connection part; wherein the first key part is arranged at the opening, and along the thickness direction of the shell body, the projection of the first key part is located in the opening; the rigidity of the shell body is greater than the rigidity of the flexible connection part.

[0327] In one application scenario, the first button portion 13 on the button body is aligned with the opening 101, and at least a portion of the flexible connection portion 12 is stacked with the outer periphery of the opening 101 on the shell body 11. The flexible connection portion 12 and the shell body 11 are connected by a process such as hot pressing. This method can simplify the manufacturing process and improve production efficiency.

[0328] In some embodiments, the shell body 11 includes a first support layer 111 and a second support layer 112. The first support layer 111 has a first opening 1011, and the second support layer 112 has a second opening 1012. Figure 32 The operation of stacking the shell body 11 and the button body in step S13 specifically includes steps S21 to S22.

[0329] Step S21: stacking the first supporting layer and the key body so that the key body covers the first opening.

[0330] Step S22: stacking a second supporting layer on a side of the button body facing away from the first supporting layer, such that the button body covers the second opening.

[0331] At least part of the flexible connection portion 12 is laminated between the first support layer 111 and the second support layer 112 ; the stiffness of the first support layer 111 and the stiffness of the second support layer 112 are both greater than the stiffness of the flexible layer.

[0332] This arrangement can fix the flexible connection part 12 from both sides through the first supporting layer 111 and the second supporting layer 112 , thereby improving the fixing stability between the flexible connection part 12 and the shell body 11 , and further improving the connection stability between the shell body 11 and the button body.

[0333] In some embodiments, the step S21 further includes: stacking the first supporting layer 111 and the button body so that the button body covers the first opening 1011; then covering the first positioning film 316 on the outside of the first supporting layer 111, covering the first opening 1011 of the first supporting layer 111 and the button body.

[0334] In some embodiments, the step S22 also includes: stacking the second supporting layer 112 on the side of the button body away from the first supporting layer 111, and making the button body cover the second opening 1012, and then covering the second positioning film 317 on the outside of the second supporting layer 112; the second positioning film 317 covers the second opening 1012 and the button body.

[0335] The provision of the first positioning film 316 and the second positioning film 317 can reduce or prevent the surface material of the case body 11 (e.g., the first supporting layer 111 and the second supporting layer 112) from contacting the first button portion 13 located within the opening 101 during the molding process of the protective case 10, thereby causing the surface of the first button portion 13 to become brittle or hard, thereby affecting the button's functionality. Therefore, this embodiment can improve the reliability of the first button portion 13 and the protective case 10.

[0336] In other embodiments, the shell body 11 and the second supporting layer 112 may be stacked first and then combined with the first supporting layer 111 to ensure that the button body firmly covers the opening 101 .

[0337] In some embodiments, any one or more of the flexible connection portion 12, first flexible layer 301, second flexible layer 302, third flexible layer 303, fourth flexible layer 304, and fifth flexible layer 305 described in the above embodiments may be a TPU film structure. In other embodiments, the flexible layers and flexible connection portions may also be made of silicone, latex, rubber, or other materials.

[0338] The tensile strength of the TPU film structure, as measured according to ASTM standards, is 38.5 MPa; the ultimate elongation, as measured according to ASTM D412, is 600%; and the tensile stress at 100% elongation, as measured according to ASTM D412, is 11.1 MPa. This configuration improves the elasticity and structural stability of the film structure, thereby enhancing the reliability and service life of the protective case 10.

[0339] The second positioning film and the flexible layer can be repeatedly provided on the inner side of the shell body, or one of them can be provided; the first positioning film and the flexible layer can be repeatedly provided on the outer side of the shell body, or one of them can be provided.

[0340] Example Group 2

[0341] In some embodiments, a conductive layer 50 may be provided for the embodiments where the conductive layer 50 is not provided in the other embodiments described above. For specific implementations, reference may be made to the embodiments described above where the conductive layer 50 is provided.

[0342] The protective shell 10 with a conductive structure is not limited to the above embodiment.

[0343] In some embodiments, as Figure 33 As shown, Figure 33 This is a structural diagram of another embodiment of the partial structure of the protective shell of the present application. The protective shell 10 includes: a shell body 11; a conductive part 17, which covers a partial area of ​​the shell body 11 and is integrally arranged with the shell body 11. When the protective shell 10 is equipped with an electronic device 20, the conductive part 17 covers the buttons of the electronic device 20 along the thickness direction z of the shell body 11.

[0344] like Figure 1 As shown, the shell body 11 defines a receiving cavity 110 for accommodating at least part of the electronic device 20; Figure 33 、 34 As shown, the conductive portion 17 includes a flexible connection portion 12 and a first button portion 13.

[0346] In some embodiments, the conductive portion 17 covers the inner side of the partial area. This structure allows the conductive portion 17 to be placed closer to the electronic device 20 when the protective case 10 and the electronic device 20 are assembled, thereby improving the control sensitivity of the electronic device 20. If the conductive portion 17 is on the outside, it may be affected by environmental factors other than fingers (such as humidity and stray capacitance). However, the internal conductive portion 17 can reduce such interference and make the capacitive coupling more stable.

[0347] In some embodiments, the case body 11 has an opening 101, and the conductive portion 17 at least covers the opening 101. When the protective case 10 is assembled with the electronic device 20, the opening 101 is positioned corresponding to the key. In this manner, the thickness of the protective case 10 can be adjusted to correspond to the key position, and the effect of the greater rigidity of the case body 11 on key operation can be reduced, thereby improving the control sensitivity of the electronic device 20.

[0348] In some embodiments, as Figure 34 As shown, Figure 34 This is a schematic structural diagram of another embodiment of the protective shell structure of the present application.

[0368] Example Group 3

[0369] In some embodiments, a conductive layer 50 may be provided for the embodiments where the conductive layer 50 is not provided in the other embodiments described above. For specific implementations, reference may be made to the embodiments described above where the conductive layer 50 is provided.

[0370] The protective shell 10 with a conductive structure is not limited to the above embodiment.

[0371] In some embodiments, as Figure 28 As shown, the protective shell 10 includes: a shell body 11; a first button portion 13, which is connected to the shell body 11, and the inner surface of the first button portion 13 protrudes inward relative to the inner surface of the shell body 11 to form a first protrusion 134 on the inner side of the shell body 11; wherein, when the protective shell 10 is equipped with an electronic device 20, the first protrusion 134 covers the buttons of the electronic device 20 along the thickness direction z of the shell body 11.

[0372] The key of the electronic device 20 may be a function key 21 .

[0373] On the one hand, the first raised portion 134 can shorten the distance between the protective case 10 and the keys of the electronic device 20 mounted therein, or provide an interference fit, providing timely tactile feedback to the user, thereby improving the sensitivity of the keys of the electronic device 20 to the external force applied to the case body 11. On the other hand, compared to the solution of improving key sensitivity by exposing the keys by providing an opening 101 in the case body 11, the present application improves key sensitivity by shortening the distance between the first button portion 13 and the keys of the electronic device 20 through the first raised portion 134 within the case body 11. Furthermore, the first raised portion 134 covers the keys of the electronic device 20, preventing dust, liquid, and other foreign matter from penetrating the key area and improving the protection of the electronic device 20. Furthermore, the enveloping design of the first button portion 13 around the keys of the electronic device 20 gives the protective case 10 a unibody aesthetic. When the electronic device 20 is mounted therein, the appearance of the protective case 10 is not affected by the appearance of the keys of the electronic device 20. Thus, the protective case 10 combines functionality with aesthetics.

[0374] In some embodiments, when the protective case 10 and the electronic device 20 are assembled, the first protrusion 134 is arranged to interfere with the buttons of the electronic device 20. In this way, when the electronic device 20 is assembled in the protective case 10, the first button portion 13 abuts against the buttons of the electronic device 20, thereby pre-pressing the buttons and improving the sensitivity of the buttons of the electronic device 20 to the external force applied to the case body 11.

[0375] In some embodiments, the protrusion height of the first protrusion 134 is 0.1 mm to 0.5 mm. Detailed analysis and extension of this embodiment can refer to the above embodiments.

[0376] In some embodiments, the protrusion height of the first protrusion 134 is 0.2 mm to 0.3 mm. Detailed analysis and extension of this embodiment can refer to the above embodiments.

[0377] In some embodiments, the first button portion 13 is integrally formed with the case body 11. This improves the connection strength between the first button portion 13 and the case body 11, more effectively resisting external impact and pressure, thereby increasing the structural stability of the protective case 10 and improving the protective effect of the protective case 10 on the electronic device 20.

[0378] In one application scenario, the function key 21 of the electronic device 20 is concave relative to the outer surface of the electronic device 20. In this way, when the protective case 10 is assembled with the electronic device 20, the first protrusion 134 can adapt to fill the concave to improve the operation accuracy of the first button portion 13.
