Description

Technical Field

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

[0002] Electronic devices such as mobile phones and laptops are usually protected by protective cases. In order to protect electronic devices, protective cases are usually rigid and hard, with poor plasticity or elasticity. This makes it inconvenient to operate the buttons on electronic devices through the protective case, and usually requires a large external force to operate the buttons effectively, resulting in low button sensitivity. Utility Model Content

[0003] To address the aforementioned technical problems, this application proposes a protective casing to improve the sensitivity of button operation on electronic devices.

[0004] This application provides a protective case, the protective case comprising: a case body; a first button portion connected to the case body, wherein the inner surface of the first button portion protrudes inward relative to the inner surface of the case body to form a first protrusion on the inner side of the case body; wherein, when an electronic device is mounted on the protective case, the first protrusion covers the button of the electronic device along the thickness direction of the case body.

[0005] The beneficial effects of this application's technical solution are as follows: The protective shell provided by this application includes a shell body and a first button portion. The first button portion is connected to the shell body, and the inner surface of the first button portion protrudes inward relative to the inner surface of the shell body to form a first protrusion on the inner side of the shell body. When an electronic device is mounted on the protective shell, the first protrusion covers the button of the electronic device along the thickness direction of the shell body. In this way, on the one hand, the first protrusion can shorten the distance between the protective shell and the button of the electronic device mounted in the protective shell, or allow for interference fit, thereby improving the sensitivity of the button operation to external forces applied to the shell body; this application improves the button operation sensitivity through a protrusion structure inside the shell body.

[0049] Example Group 1

[0050] In some embodiments, such as Figures 1 to 36 As shown, the protective shell 10 includes a shell body 11, a flexible connecting part 12, and a first button part 13. The shell body 11 has an opening 101. The first button part 13 is integrally formed with the shell body 11 through the flexible connecting part 12 and is located at the opening 101. Along the thickness direction z of the shell body 11, the projection of the first button part 13 is located inside the opening 101.

[0051] The housing body 11 defines a receiving cavity 110 for accommodating at least a portion of the electronic device 20, and the opening 101 communicates with the receiving cavity 110. A first button portion 13 is used to abut against or be adjacent to the function key 21 of the electronic device 20 installed in the housing body 11, so that the function key 21 of the electronic device 20 can be triggered when a human touches the first button portion 13.

[0052] The first button section 13 is the area where the user performs button operations. For example, in one application scenario, the protective case 10 is configured to protect an electronic device 20. The electronic device 20 is equipped with function keys 21. When the electronic device 20 is mounted on the protective case 10, the first button section 13 covers at least part of the function keys 21. Therefore, the user can trigger the corresponding function key 21 by pressing the first button section 13, thereby ensuring the normal response of the function keys 21 during use.

[0053] In some embodiments, the first button portion 13 can directly abut against the function key 21, or the first button portion 13 and the function key 21 can have a very small gap, so that when the user's finger is placed or slid 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 pressure to the function key 21, so as to avoid the function key 21 being triggered incorrectly due to the above reasons.

[0054] 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 with the opening 101, which can be parallel to the pressing direction of the user's button operation. For example, in one application scenario, the shell body 11 has a side wall 113 and a bottom wall 114. The side wall 113 is located on the outer periphery of the bottom wall 114, and the side wall 113 and the bottom wall 114 enclose to form a receiving cavity 110. The receiving cavity 110 is configured to accommodate at least a portion of the electronic device 20. When the opening 101 is located on the side wall 113, the aforementioned thickness direction z refers to the thickness direction of the side wall 113 of the shell body 11. At this time, the thickness direction z is perpendicular to the side wall 113, and the pressing direction of the user on the first button portion 13 is perpendicular to the side wall 113. When the opening 101 is located on the bottom wall 114, the aforementioned thickness direction z refers to the thickness direction of the bottom wall 114. At this time, the thickness direction z is perpendicular to the bottom wall 114, and the pressing direction of the user on the first button portion 13 is perpendicular to the bottom wall 114.

[0055] In other embodiments, the housing body 11 may include a top wall, and the top wall, bottom wall 114 and side wall 113 enclose a fully enclosed receiving cavity 110 to completely enclose the electronic device 20.

[0056] 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 located on the side, the opening 101 is opened on the side wall of the shell body 11. When the function key 21 of the electronic device is located on the back, the opening 101 is opened on the bottom wall of the shell body 11.

[0057] The receiving cavity 110 is used to house and couple the electronic device 20. One or more coupling structures may also be provided within the receiving cavity 110 for holding and coupling the electronic device 20 within the receiving cavity 110. These coupling structures include, but are not limited to, flexible elements, guide rails, channels, latches, magnets, and friction coupling elements. It is understood that the coupling between the protective housing 10 and the electronic device 20 is continuous, ensuring that the protective housing 10 and the electronic device 20 will not accidentally separate during use. It is further understood that the protective housing 10 and the electronic device 20 can be removably coupled, allowing the electronic device 20 to be removed as needed by the user. Thus, the coupling between the protective housing 10 and the electronic device 20 is reversible, allowing each to be restored to its state before coupling.

[0058] In some embodiments, the protective shell 10 may be a single, integral structure or formed from multiple discrete parts (of the same or different materials). For example, the back of the protective shell 10 may be formed of a rigid material, while other parts of the protective shell 10 (e.g., the frame) may be formed of an elastic material. Alternatively, the protective shell 10 may include an upper shell and a lower shell, or a left shell and a right shell. In some embodiments, an additional layer may also be provided within the receiving cavity 110. The additional layer may be a material for contacting the electronic device 20, including but not limited to microfibers, fabrics, foams, rubber, etc. The additional layer may also use materials for heat dissipation and / or to prevent damage to the electronic device 20.

[0059] It should be noted that after the molding process of the protective shell 10 is completed, the components such as the first button part 13 and the flexible connection part 12 located near the opening 101 in the thickness direction z of the shell body 11 may be displaced due to molding processes such as hot pressing. Therefore, in this application, the attached drawings are only schematic diagrams of the layered structure of the components of the protective shell 10.

[0060] The flexible connecting part 12 connects the first button part 13 to the shell body 11, making the first button part 13 integrally connected to the shell body 11. The force-bearing portion of the flexible connecting part 12 can be displaced relative to the shell body 11. Therefore, when the first button part 13 is subjected to force, relative displacement occurs between it and the shell body 11 through the flexible connecting part 12. The projection of the first button part 13 along the thickness direction z of the shell body 11 is located within the opening 101. Therefore, the user can operate the electronic device 20 inside the protective shell 10 by pressing the first button part 13, causing it to displace along the thickness direction z of the shell body 11.

[0061] The projection of the first button portion 13 along the thickness direction z of the shell body 11 into the opening 101 means that the first button portion 13 is located inside the opening 101, or the first button portion 13 is located inside or outside the opening 101 along the thickness direction z of the shell body 11, and is directly opposite the opening 101.

[0062] There are several ways to achieve a one-piece design. For example, heating or pressurizing can melt the relevant substances in at least two material layers, allowing them to 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 with adhesive or similar materials and then cured. This one-piece design results in at least two material layers forming an inseparable whole without violent intervention; this inseparable whole is also known as a "one-piece integral design."

[0063] In some embodiments, the flexible connector 12 and the shell body 11 are integrally thermoformed. This ensures the connection strength between the flexible connector 12 and the shell body 11 while simplifying the manufacturing process and improving production efficiency.

[0064] In some embodiments, the flexible connector 12 and the housing body 11 can be two-color injection molded. For example, when the flexible connector 12 and the first button portion 13 are made of different types of thermoplastic resin, the flexible connector 12 and the first button portion 13 can be two-color injection molded with the housing body 11. This can reduce labor and logistics costs and avoid tolerance accumulation caused by separate assembly.

[0065] The flexible connecting part 12 is easily deformed under external force, which can improve the flexibility of the relative displacement between the first button part 13 and the shell body 11, and improve the sensitivity and reliability of external operation of the electronic device 20. Furthermore, the shell body 11 can form a rigid area of ​​the protective shell 10, which can effectively protect the electronic device 20 as a whole. Furthermore, the shell body 11 and the first button part 13 can be integrally molded, which can improve the structural stability of the protective shell 10, save material costs, and facilitate the miniaturization of the combined structure formed by the protective shell 10 and the electronic device 20.

[0066] In this way, on the one hand, the first button portion 13 located at the opening 101 of the shell body 11 is connected to the shell body 11 via the flexible connecting portion 12, which improves the mobility of the first button portion 13 relative to the shell body 11, giving the protective shell 10 a local flexible area. This improves the tactile feel of the first button portion 13 and reduces the impact of the shell body 11 on the operation of the first button portion 13, thereby improving the control accuracy of the electronic device 20. On the other hand, by setting the first button portion 13 at the opening 101 of the shell body 11 and connecting the first button portion 13 to the shell body 11 via the flexible connecting portion 12, the sealing of the opening 101 is increased by the first button portion 13 and the flexible connecting portion 12, thereby improving the problem of the corresponding button of the electronic device 20 being exposed and not effectively protected. Furthermore, the shell body 11, the flexible connecting portion 12, and the first button portion 13 are integrally formed, which improves the structural stability of the protective shell 10 and improves the problem of insufficient connection strength and easy detachment caused by separate assembly, thereby further improving the protection capability of the electronic device 20.

[0067] In some embodiments, the stiffness of the shell body 11 is greater than the stiffness of the flexible connection 12. Stiffness refers to the magnitude of the force required for a structure to produce a unit deformation when an external force is applied, and it can reflect the flexibility of a material; in most cases, the greater the stiffness of a material, the smaller its deformation capacity and the smaller its flexibility.

[0068] The stiffness of the shell body 11 refers to the force required to produce a unit deformation when an external force is applied to the shell body 11, and the stiffness of the flexible connection 12 refers to the force required to produce a unit deformation when an external force is applied to the flexible connection 12. When the same force is applied to the shell body 11 and the flexible connection 12, the deformation of the shell body 11 is less than the deformation of the flexible connection 12.

[0069] The rigidity of the shell body 11 is greater than that of the flexible connecting part 12, which makes it easier to press and rebound the first button part 13, making the feedback of the first button part 13 clearer and its tactile feel more comfortable; and the flexible connecting part 12 is easily deformed under external force, which can reduce the difficulty of disassembling and assembling the protective shell 10; furthermore, as the main body of the protective shell 10, the shell body 11 can effectively protect the entire electronic device 20.

[0070] The materials of the shell body 11 and 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 high elastic modulus material such as polycarbonate (PC); the flexible connection part 12 can be made of low elastic modulus material such as thermoplastic polyurethane (TPU), rubber, or silicone. Alternatively, the shell body 11 and the flexible connection part 12 can be made of the same material, such as TPU, but different stiffness TPUs can be used, or the thickness of the shell body 11 can be greater than the thickness of the flexible connection part 12, thereby making the stiffness of the shell body 11 greater than that of the flexible connection part 12.

[0071] Understandably, in some embodiments, the stiffness of each region of the flexible connection 12 can be kept consistent, while in other embodiments, the stiffness of each region can be inconsistent, and no specific limitation is made.

[0072] In some embodiments, the stiffness of all regions of the flexible connection portion 12 is consistent, or the stiffness 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.

[0073] In some embodiments, the stiffness of all regions of the shell body 11 is uniform, 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 12 and the shell body 11 during deformation.

[0074] In some embodiments, the stiffness of the first button portion 13 is less than the stiffness of the shell body 11, so that the deformation capacity of the first button portion 13 is greater than the deformation capacity of the shell body 11, making it easier for the user to press and operate.

[0075] 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 capability and deformation recovery force of the flexible connection portion 12 relative to the shell body 11 can be improved, thereby improving the clarity of the press-and-rebound operation and the touch feel of the first button portion 13.

[0076] In some embodiments, the elasticity of the first button portion 13 is less than that of the flexible connecting portion 12, which can improve the problem that the first button portion 13 deforms after long-term use and cannot match 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 connecting portion 12. This improves the wear resistance of the first button portion 13.

[0077] Understandably, the shell body 11 is used to protect electronic devices, therefore it needs to have characteristics such as impact resistance, wear resistance, and thinness. Meanwhile, the flexible connection part 12, as the spring-loaded carrier of the first button part 13, needs to have high elasticity and high fatigue resistance. Therefore, by selecting more suitable materials for the shell body 11 and the flexible connection part 12 according to different usage requirements, and through the complementary properties of the materials in each part, the balance between the function and user experience of the protective shell can be maximized.

[0078] In some embodiments, the flexible connection portion 12 is in a planar tensioned state and is located within the opening 101. Compared to setting the flexible connection portion 12 in a pleated shape, the flexible connection portion 12 in a planar tensioned state has a clearer rebound, thus making the pressing rebound feedback effect of the first button portion 13 obvious and the pressing feel better.

[0079] In some embodiments, the extending direction of the flexible connecting portion 12 is consistent with the extending direction of the outer surface of the shell body 11. This allows the flexible connecting portion 12 to be stretched and unfolded in a planar manner, which can improve the rebound effect of the flexible connecting portion 12 and further improve the pressing feel of the first button portion 13.

[0080] In some embodiments, the flexible connection portion 12 is made of a light-transmitting material. Thus, in certain scenarios, such as when the function keys of an electronic device are illuminated, the flexible connection portion 12 can transmit light, enhancing the visual appeal of the protective case. In other embodiments, the flexible connection portion 12 may also be made of an opaque material, or a light-shielding layer may be applied to its outer surface.

[0081] In some embodiments, the first button portion 13 further includes an outer surface layer, which forms the outer surface of the first button portion 13. The coefficient of friction of the outer surface layer is less than that of the flexible connection portion 12. The outer surface layer can be made of a material with a low coefficient of friction that facilitates sliding touch. For example, the outer surface layer can be a resin-impregnated and polished aramid fiber layer, or a smooth and wear-resistant material such as sapphire glass. Alternatively, the outer surface layer can be made of a polymer material with a low coefficient of friction, which can be formed by spraying it onto the outer surface of the first button portion 13. Making the coefficient of friction of the outer surface layer less than that of the flexible connection portion 12 reduces the frictional force required for the user to touch the first button portion 13. This results in a smoother and more fluid tactile feel at the first button portion 13, improving the smoothness of operation of the function keys of the electronic device. In some embodiments, the outer surface layer and the shell body 11 are made of the same material. This gives the first button portion 13 and the shell body 11 a consistent appearance, resulting in better overall aesthetic consistency of the protective shell 10.

[0082] Furthermore, both the outer outer layer and the main shell 11 are 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 outer layer and the main shell 11 have advantages such as wear resistance, smoothness, and ease of sliding touch.

[0083] In some embodiments, the outer surface 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, facilitating smooth touch; for example, it can be a resin-impregnated and polished aramid fiber layer, or a smooth and wear-resistant material such as sapphire glass. The smooth layer enhances the smoothness of the user's operation of the electronic device's function keys by touching the first button portion 13.

[0084] In some embodiments, the outer layer is a wear-resistant layer formed on the outer surface of the first button portion 13. Specifically, this wear-resistant layer can be made of wear-resistant materials such as aramid fiber or sapphire glass. By providing the wear-resistant layer, the scratch resistance of the first button portion 13 can be improved, thereby ensuring the appearance stability of the first button portion 13.

[0085] It should be noted that the outer surface layer can be provided with a smooth layer or a wear-resistant layer alone, or a combination of smooth and wear-resistant layers, so as to improve the smoothness of operation of the function keys of the electronic device by the first button part 13 or have the advantages of wear resistance, smoothness and easy sliding touch, all of which fall within the scope of this embodiment and are not limited here.

[0086] In one application scenario, the sensor button 211 of the electronic device 20 is located on its side, 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 shell 10, with the sensor button 211 protruding 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 shell body 11 to accommodate the protruding sensor button 211, and this groove also forms a deformation space for the flexible connection portion 12, thereby improving the operational reliability of the entire first button portion 13.

[0087] In some embodiments, such as Figure 5 , Figure 35 and Figure 36 The first button part 13 includes a fiber layer 41.

[0088] In some applications, the first button section 13 has a single-layer structure, consisting only of the fiber layer 41, for example, see [reference needed]. Figure 5 , Figure 35 , Figure 5 The protective shell portion structure is shown as a layered structure before the molding process in one embodiment. Figure 35 The diagram shows a cross-sectional structure of the protective shell after the molding process in one embodiment, 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 This is a cross-sectional structural diagram of another embodiment of the protective shell after the molding process of this application; the first button part 13 includes a button body 131 and a fiber layer 41. The fiber layer 41 covers the side of the button body 131 away from the electronic device. The user can press the first button part 13 by pressing the fiber layer 41.

[0089] In this way, the tactile feel of the first button portion 13 can be improved by utilizing the fiber layer 41, thereby enhancing the user experience. Furthermore, the fiber layer 41 facilitates the improvement of the appearance of the first button portion 13, thereby enhancing the overall aesthetics of the protective case 10.

[0090] In some embodiments, the fiber layer 41 may also surround the outer periphery of the button body 131, or may be disposed on the inner and outer sides of the button body 131.

[0091] In some embodiments, such 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.

[0092] Wherein, along the thickness direction z of the shell body 11, the projection of the flexible connecting part 12 covering the projection of the first button part 13 and the opening 101 means that the projection of the flexible connecting part 12 towards the thickness direction z of the shell body 11 covers the projection of the first button part 13 and the opening 101, without limiting whether the first button part 13 is completely located within the opening 101.

[0093] The beneficial effects of the above-mentioned configuration are that the flexible connecting part 12 covers the first button part 13 and the opening 101 in the thickness direction z, which facilitates the connection between the flexible connecting part 12 and the side wall 113 of the opening 101, and the connection between the flexible connecting part 12 and the first button part 13. This can improve the connection stability between the flexible connecting part 12 and the first button part 13. At the same time, the covering design of the flexible connecting part 12 can effectively reduce the interference of external factors such as dust on the first button part 13, improve the reliability of the first button part 13, and improve the protective effect of the protective shell 10 on the electronic device 20.

[0094] In some embodiments, such as Figure 6 As shown, along the thickness direction z of the shell body 11, the flexible connecting portion 12 partially covers the first button portion 13 to achieve connection with the first button portion 13; or as... Figure 7As shown, along the thickness direction z of the shell body 11, the flexible connecting 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 connecting portion 12 fully or partially surrounds the outer periphery of the first button portion 13, and the side of the flexible connecting 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 integral structure.

[0095] It should be noted that the improvement to the flexible connection part 12 is not limited to embodiments where the shell body has a double-layer structure. In embodiments where the shell body has a single-layer structure or a three-layer or higher structure (not shown in the figure), the same principle can still be applied. Figures 5 to 7 The embodiment shown improves the flexible connection portion 12.

[0096] To improve the structural stability of the protective shell 10, the connection method between the flexible connector 12 and the shell body 11 can be improved. For example, in some embodiments, such as Figure 5 As shown, 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. The second support layer 112 is stacked with at least a portion of the first support layer 111 along the thickness direction z of the shell body 11, and the second support layer 112 has a second opening 1012. 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 portion 12 is stacked 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 connection portion 12. Thus, the local resistance of the first support layer 111 and the second support layer 112 to the intrusion of external objects is greater than that of the flexible connection 12 to the intrusion of external 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 and inner layer materials forming the shell body 11, the first support layer 111 and the second support layer 112 can be materials with high rigidity, the first support layer 111 and the second support layer 112 can be rigid thermosetting resin materials; the first support layer 111 and the second support layer 112 can also be materials with a certain degree of 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 impregnated with epoxy resin to give it high rigidity and hardness; the first support layer 111 and the second support layer 112 can be formed into the shell body 11 by hot pressing.

[0097] In some embodiments, the elasticity of the first support layer 111 and the second support layer 112 is less than that of the flexible connection portion 12, which makes the flexible connection portion 12 easy to deform and recover from deformation, thereby enabling the operation of the electronic device 20 inside the protective shell 10, while the rigid layer is not easy to deform, thus improving the protection effect on the electronic device 20.

[0098] The first opening 1011 and the second opening 1012 completely or partially overlap. At least partial overlap means that the projections of the opening 101 region of the first opening 1011 and the opening 101 region of the second opening 1012 along the thickness direction z at least partially overlap. This reduces the obstruction of the second opening 1012 by the peripheral region of the first opening 1011 and the obstruction of the first opening 1011 by the peripheral region of the second opening 1012, thereby forming the opening 101 of the shell body 11 at their overlapping portion. This opening 101 can be used to house the first button portion 13. The first support layer 111 and the second support layer 112 completely or partially overlap, without specific limitations.

[0099] For example, in some embodiments, such as Figure 5 As shown, the first opening 1011 and the second opening 1012 are the same size and completely aligned. The projection of the flexible connecting portion 12 along the thickness direction z covers the first opening 1011 and its outer peripheral area, as well as the second opening 1012 and its outer peripheral area. For example, in some embodiments, such as... Figure 8 As shown, the size of the first opening 1011 is larger than the size of the second opening 1012, and they at least partially overlap along the thickness direction z. The projection of the flexible connecting portion 12 along the thickness direction z covers the first opening 1011 and its outer peripheral area, as well as the second opening 1012 and its outer peripheral area. For example, in some embodiments, such as... Figure 9 As shown, the size of the first opening 1011 is smaller than the size of the second opening 1012. Along the thickness direction z, the two overlap at least partially. The projection of the flexible connection portion 12 along the thickness direction z covers the first opening 1011 and its outer peripheral area, as well as the second opening 1012 and its outer peripheral area.

[0100] At least a portion of the flexible connecting part 12 is stacked between the first support layer 111 and the second support layer 112. The first support layer 111 and the second support layer 112 can fix the flexible connecting part 12, achieving a tight connection between the flexible connecting part 12 and the first and second support layers 111 and 112. This improves the connection reliability between the flexible connecting part 12 and the shell body 11, and enhances the positional stability and deformation controllability of the flexible connecting part 12 under stress. Furthermore, the flexible connecting part 12 can be a TPU film layer, which reduces the thickness of the flexible connecting part 12, increases the deformation space for elastic deformation, and thus increases the displacement distance of the first button part 13 when pressed, improving the rebound force.

[0101] In other embodiments, when the flexible connection portion 12 adopts other structural forms, it can also be improved in a similar way to achieve a fixed connection between the flexible connection portion 12 and the first support layer 111 and the second support layer 112, thereby achieving a connection between the flexible connection portion 12 and the shell body 11. Therefore, through the laminated structure design, the connection stability between the flexible connection portion 12 and the shell body 11 can be effectively improved, and subsequent processing is convenient.

[0102] In other embodiments, the shell body 11 may also include only a first support layer 111, with at least a portion of the first support layer 111 and the flexible connection portion 12 stacked together to facilitate the tight bonding of the flexible connection portion 12 and the first support layer 111 by hot pressing or other molding processes.

[0103] To improve the connection stability between the flexible connecting portion 12 and the first button portion 13, the flexible connecting portion 12 can be further improved. In some embodiments, such as 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.

[0104] Specifically, the projection of the first flexible layer 301 onto the thickness direction z of the shell body 11 covers the first button portion 13, and the projection of the second flexible layer 302 onto the thickness direction z of the shell body 11 also covers the first button portion 13. This can be understood as the first flexible layer 301, the first button portion 13, and the second flexible layer 302 being sequentially stacked 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 in the middle through their stacked structure, which improves the tightness of the connection between the first button portion 13 and the flexible connecting portion 12, and enhances the protection of the first button portion 13, preventing displacement or damage during use, thereby further improving the stability and durability of the overall structure. The second flexible layer 302 inside the first button portion 13 can also improve or reduce the marks left on the first button portion 13 due to long-term contact with the function keys 21 of the electronic device 20.

[0105] In some embodiments, such as Figure 11 As shown, Figure 11 yes Figure 5 In the enlarged structural diagram of region B in the embodiment, there is a gap d between the first button part 13 and the inner wall of the opening 101.

[0106] The gap d between the first button part 13 and the inner wall of the opening 101 means that the projection of the first button part 13 along the thickness direction z of the shell body 11 is located inside 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 there is a gap d between the first button part 13 and the inner wall of the opening 101 in the vertical plane of the thickness direction z of the shell body 11. When the first button part 13 is pressed along the thickness direction z, the gap d can provide a certain buffer space to reduce the collision and friction between the first button part 13 and the shell body 11.

[0107] 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, so as to ensure the flexibility of button operation, reduce the risk of button jamming, and reduce the friction between the first button part 13 and the shell body 11 when the user performs button operation.

[0108] In some embodiments, the first button portion 13 is located 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 connecting portion 12 is integrally formed with the first button portion 13 to cover or fill the gap d. The design of the flexible connecting portion 12 covering or filling the first annular gap d can effectively reduce interference from 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 shell 10 on the electronic device 20.

[0109] In some embodiments, such as Figure 29As shown, Figure 29 This is a cross-sectional structural diagram of an embodiment of the protective shell after the molding process. The inner wall 71 of the first button part 13, the inner wall 72 of the opening 101, and the portion 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.

[0110] Figure 29 The diagram shows a cross-sectional view of a portion of the protective shell after the molding process in one embodiment. By providing grooves 70, the flexible connection portion 12 can be provided with deformation space, reducing the difficulty of pressing for the user and improving the user's button experience.

[0111] In some embodiments, the flexible connection portion 12 includes an annular or quasi-annular region covering the gap d.

[0112] Specifically, the projection of the flexible connecting portion 12 in the thickness direction z covers the gap d. The area covered by the flexible connecting portion 12 covering the gap d can be an annular or quasi-annular area, such as a square ring or a circular ring, and is not limited thereto. The covering design of the flexible connecting portion 12 can effectively reduce the interference of external factors such as dust on the first button portion 13, improve the reliability of the first button portion 13, and improve the protective effect of the protective shell 10 on the electronic device 20.

[0113] Furthermore, the flexible connecting portion 12 has a sheet-like structure in the annular or near-annular region. This allows the flexible connecting portion 12 to unfold in a planar tension. Compared to making the annular or near-annular region of the flexible connecting portion 12 wrinkled, the sheet-like flexible connecting portion 12 has a clearer rebound, thus making the pressing rebound feedback of the first button portion 13 more obvious and the pressing feel better.

[0114] In other embodiments, the portion of the flexible connection 12 in the annular or quasi-annular region may also be corrugated. This increases the deformation range of the flexible connection 12.

[0115] To further improve the flexibility and stability of button operation, in some embodiments, such as Figure 11 As shown, the width of the gap d between the first button part 13 and the inner wall of the opening 101 is 0.5mm to 2mm.

[0116] Wherein, 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 shell body 11 toward the opening 101 and the inner wall 72 of the opening 101 in the vertical plane of the thickness direction z of the shell body 11. For example, in an application scenario, the shell body 11 forms a closed opening 101, the projection of the first button portion 13 along the thickness direction z of the shell body 11 toward the opening 101 is located inside the opening 101, and the gap d surrounds the first button portion 13 so that an annular gap is formed between the first button portion 13 and the inner wall 72 of the opening 101, and the width of this annular gap is the width of the gap d.

[0117] A larger gap d results in greater flexibility in button operation, but an excessively large gap d may reduce the positional stability of the first button part 13. Conversely, a gap d that is too small may increase friction, making button operation too stiff and negatively impacting 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 to improve the flexibility of button operation and the positional stability of the first button part 13.

[0118] 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. This further improves the comfort and durability of button operation, allowing users to receive smooth feedback when pressing the button with varying force.

[0119] 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.

[0120] The outer periphery of the opening 101 is connected to the first button portion 13 via a flexible connection portion 12. The area of ​​the flexible connection portion 12 at the gap d refers to the projected area of ​​the flexible connection portion 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 portion 13 refers to the projected area of ​​the first button portion 13 in the vertical plane.

[0121] 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., and is not specifically limited. For example, the area of ​​the flexible connection part 12 at gap d is 17.927 mm². 2 The area of ​​the first button part 13 is 31.14 mm². 2The area ratio is 0.576; for example, the area of ​​the flexible connection 12 at gap d is 81.13 mm². 2 The area of ​​the first button part 13 is 31.14 mm². 2 The area ratio is 2.605; for example, the area of ​​the flexible connection 12 at gap d is 21.068 mm². 2 The area of ​​the first button part 13 is 68.565 mm². 2 The area ratio is 0.307; for example, the area of ​​the flexible connection 12 at gap d is 93.698 mm². 2 The area of ​​the first button part 13 is 68.565 mm². 2 The area ratio is 1.367.

[0122] This design improves the button flexibility at the first button section 13 while ensuring the button area of ​​the first button section 13 has a better pressing feel, thus improving the comfort and durability of button operation and enhancing the user's button experience.

[0123] In some embodiments, the thickness of the flexible connection portion 12 at the gap d is less than the thickness of the first button portion 13.

[0124] In this context, the thickness of the flexible connecting portion 12 refers to its thickness along the thickness direction z of the shell body 11, and the thickness of the first button portion 13 refers to its thickness along the thickness direction z of the shell body 11. The thickness of the flexible connecting portion 12 is less than the thickness of the first button portion 13, which further enhances the flexibility of the flexible connecting portion 12 in elastic deformation, thus improving the displacement flexibility of the first button portion 13. In this application, the flexible connecting portion 12 at the gap d refers to the portion of the flexible connecting portion 12 corresponding to the gap d. For example, the thickness of the portion of the flexible connecting portion 12 corresponding to the gap d is less than the thickness of the first button portion 13.

[0125] 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, so as to improve the thickness consistency of the overall structure of the protective shell 10.

[0126] In some embodiments, the thickness of the flexible connection portion 12 is 0.1 mm to 0.5 mm.

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

[0128] The flexible connection portion 12 at gap d refers to the portion of the flexible connection portion 12 corresponding to gap d. The thickness of the portion of the flexible connection portion 12 corresponding to gap d is 0.1 mm to 0.5 mm. For example, the thickness of the flexible connection portion 12 at 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 capability of the flexible connection portion 12 and reduce the interference of the flexible connection portion 12 on user operation.

[0129] In some embodiments, the first button portion 13 is elongated, and the opening 101 is configured to mimic the shape of the first button portion 13.

[0130] The first button portion 13 can be configured in shapes such as circular, rectangular, or racetrack-shaped. Of course, the first button portion 13 is designed to mimic the function keys of the electronic device to facilitate user identification and observation. By making the opening 101 mimic the shape of the first button portion 13, and ensuring that the extension shape of the gap d matches the outer contour shape of the first button portion 13, visual consistency can be guaranteed; the uniformity of force distribution on the inner and outer rings of the flexible connection portion 12 can also be improved.

[0131] In some embodiments, such as Figure 4 As shown, the length h of the first button part 13 is 15mm to 19mm.

[0132] Wherein, the length h of the first button portion 13 refers to the length of the long side of the first button portion 13 in the vertical plane of 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 rectangular structure with a long side and a short side. The length h of the long side is 15mm, 16mm, 16.2mm, 16.5mm, 16.7mm, 17mm, 17.1mm, 17.3mm, 17.5mm, 17.8mm, 18mm, or 19mm, etc.

[0133] In some application scenarios, the length h of the first button portion 13 can be finely adjusted based on the size of the function key 21 of the electronic device 20.

[0134] If the length h of the first button part 13 is too long, it will affect the convenience of user operation and make it difficult to accurately control the function key 21 of the electronic device 20 by pressing the first button part 13; if the length h of the first button part 13 is too short, it will not be able to effectively cover the function key 21 area of ​​the electronic device 20 and will not be convenient for users to press the button. Therefore, the above settings can effectively improve the convenience of user operation.

[0135] In some embodiments, the length h of the first button portion 13 is 17.5mm, which enables the user to accurately trigger the function key 21 corresponding to the electronic device 20 during operation, thereby improving the user experience.

[0136] In some embodiments, such as Figure 4 As shown, the width w of the first button portion 13 is 1.5mm to 4mm.

[0137] The width w of the first button portion 13 refers to the length of the short side of the first button portion 13 in the vertical plane of 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 rectangular structure with a long side and a short side. The length of the short side is 1.5mm, 1.8mm, 2mm, 2.1mm, 2.3mm, 2.5mm, 3mm, 3.2mm, 3.3mm, 3.5mm, 3.6mm, 3.7mm, or 4mm, etc.

[0138] In some application scenarios, the width w of the first button portion 13 can be finely adjusted based on the size of the function key 21 of the electronic device 20.

[0139] If the width w of the first button portion 13 is too large, it will increase the overall size of the protective case 10, making it inconvenient for the user to operate; if the width w of the first button portion 13 is too small, it will not be able to effectively cover the function key 21 area of ​​the electronic device 20. Therefore, the above settings can effectively improve the user's operating convenience.

[0140] It is understandable that the length and width range of the first button part 13 mentioned above are the optimal ranges obtained through experiments, and some non-creative adjustments to the above ranges should also fall within the protection scope of this patent.

[0141] In some embodiments, the width of the annular or quasi-annular region, i.e., the flexible connection portion 12 at the gap d, is 0.5 mm to 2 mm.

[0142] The wider the annular or near-annular area, the more flexible the button operation. However, if it is too wide, it may reduce the positional stability of the first button part 13. If it is too small, the button operation may be too stiff, increasing friction and affecting the user experience. Therefore, the width of the annular or near-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 to improve the flexibility of button operation and the positional stability of the first button part 13.

[0143] In some embodiments, the width of the annular or near-annular region is 0.8 mm. This further improves the comfort and durability of button operation, allowing users to receive smooth feedback regardless of the pressure applied when pressing the buttons.

[0144] In some embodiments, such as Figure 3 As shown, the protective case 10 is configured to protect the electronic device 20. The electronic device 20 is provided with function keys 21. When the electronic device 20 is assembled on the protective case 10, the first button part 13 covers at least part of the function keys 21.

[0145] Wherein, the first button part 13 at least covers a portion of the function keys 21 means that after the protective shell 10 and the electronic device 20 are assembled, the projection of the first button part 13 along the thickness direction z of the shell body 11 toward the electronic device 20 covers one or more (two or more) of the multiple function keys 21 on the electronic device 20, so that the first button part 13 is correspondingly set with a portion of the function keys 21.

[0146] In this embodiment, a first button part 13 is provided at the position of the function key 21 of the protective shell 10 and the electronic device 20. Since the first button part 13 is connected to the opening 101 through the flexible connecting part 12, the first button part 13 has a strong ability to be displaced by external force. The first button part 13 can transmit external operation faster and more accurately, thereby improving the sensitivity and reliability of the external operation function key 21.

[0147] Furthermore, when assembling and disassembling the protective case 10 from the electronic device 20, the assembly and disassembly operations can also be performed at the first button part 13. The difficulty of assembling and disassembling the protective case 10 can be reduced by the displacement of the first button part 13 and the deformation capability of the flexible connection part 12.

[0148] Compared to the related technologies that expose 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 and protect the function keys 21; at the same time, the design of the protective shell 10 reduces the interference of the protective shell 10 on the user's operation of the function keys 21.

[0149] In some embodiments, the function key 21 includes a touch-sensitive button 211. Specifically, the touch-sensitive button 211 may be a touch-sensitive button 211, so that a human body can control or access the corresponding functions of the electronic device 20 by touching the touch-sensitive button 211, such as the shooting function, the near field communication (NFC) function, etc.

[0150] In some embodiments, a sensor button 211 is provided on the outer surface of the electronic device 20. A first button portion 13 is attached to the outer surface of the sensor button 211 to protect the sensor button 211 and to facilitate the user to operate the sensor button 211 by touching the first button portion 13.

[0151] The sensing button 211 may include a capacitive sensing button 211 or a resistive sensing button 211, etc.

[0152] In some embodiments, the sensing button 211 includes a capacitive sensing button 211. The deformability of the flexible connecting portion 12 and the displaceability of the first button portion 13 can be utilized to transmit external pressing operations to the capacitive sensing button 211, thereby achieving a first function operation of the electronic device 20. Even if the first button portion 13 is an insulator, a capacitive coupling effect still exists between a conductive body such as a user and the capacitive sensing button 211. Therefore, when the conductive body such as a user moves relative to the first button portion 13, one or both of the coupling capacitance value and coupling position of the capacitive sensing button 211 will change. This facilitates the electronic device 20 in recognizing the operation of the capacitive sensing button 211 by the conductive body such as a user, thereby enabling a second function operation of the electronic device 20. The aforementioned first function and second function can be two different functions of the electronic device 20, or different operations of the same function of the electronic device 20.

[0153] In some embodiments, the sensing button 211 can be a resistive sensing button 211. The deformability of the flexible connecting part 12 and the displacement of the first button part 13 can be used to transmit the external pressing operation to the resistive sensing button 211, so as to control the electronic device 20 through the pressing operation. Different functions of the electronic device 20 can be controlled by different pressing durations and other parameters.

[0154] In some embodiments, multiple function keys 21 of the electronic device 20 can be implemented by a combination of capacitive sensing buttons 211, resistive sensing buttons 211, etc.

[0155] In some embodiments, such as Figure 3 As shown, the electronic device 20 includes a mobile phone, the sensor button 211 includes a camera button 212, the protective case 10 is provided with a side wall 113 for surrounding the side of the mobile phone, the first button part 13 is provided on the side wall 113, and the camera button 212 is located on the inner side of the first button part 13.

[0156] In one application scenario, the display surface of the mobile phone is defined as the front surface, and 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 case 10 is set to correspond to the back surface of the mobile phone; the first button 13 is set to correspond to the shooting button 212 on the mobile phone, so that the shooting button 212 can be operated through the first button 13.

[0157] In one application scenario, to improve the convenience of mobile phone operation, the function key 21 of the mobile phone is usually located on the right side of the phone (in the default screen display mode). The first button part 13 on the protective case 10 is located on the right wall of the protective case 10, corresponding to the function key 21 of the mobile phone. The function key 21 includes a sensor button 211, which includes a shutter button 212 for realizing the mobile phone's camera function. The shutter button 212 is electrically connected to the main control of the electronic device 20, such as a microprocessor unit. The shutter button 212 can convert user actions such as pressing or touching the shutter button 212 into electrical signals and transmit them to the microprocessor unit, so that the microprocessor unit controls the camera component and other related functional components of the electronic device 20 to work, thereby realizing at least one of the following functions: camera opening / closing, focus adjustment, shooting, and video recording.

[0158] In some embodiments, the first button 13 may also be configured to correspond with other function keys 21 of the electronic device 20. The function key 21 may be a touch button 211 or a press button. The function key 21 may also perform functions such as power on / off, volume adjustment, and screenshot.

[0159] In some embodiments, such as Figure 11 As shown, the thickness t of the first button portion 13 is 0.1 mm to 1.2 mm.

[0160] The thickness t of the first button portion 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 portion 13, the more space is available for the displacement of the first button portion 13, which is beneficial for effectively transmitting the pressing operation through the first button portion 13. The thinner the thickness of the first button portion 13, the lower the overall resistance of the first button portion 13, reducing the operating distance between the user and the electronic device 20. This reduces the interference of the first button portion 13 of the protective shell on the user's operation of the electronic device 20, and improves the user's control sensitivity and reliability of the electronic device 20. On the other hand, the thickness t of the first button portion 13 is greater than or equal to 0.1 mm, which improves the protection capability of the first button portion 13 for the function key 21, and also increases the service life of the first button portion 13, reducing the risk of the first button portion 13 breaking during operation.

[0161] In some embodiments, the specific thickness t of the first button portion 13 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, etc.

[0162] The first button portion 13 is attached to the surface of the sensor button 211 of the electronic device 20; it can limit the effective thickness range of the first button portion 13, and enable the user to conveniently operate the sensor button 211 of the electronic device 20 through the protective case 10.

[0163] In some embodiments, such as Figure 2 , Figure 3 As shown, the shell body 11 has a side wall 113 and a bottom wall 114. The side wall 113 is located on the outer periphery of the bottom wall 114, so as to form a receiving cavity 110 together with the bottom wall 114. The receiving cavity 110 is configured to receive an electronic device 20. The opening 101 is located on the side wall 113 or the bottom wall 114.

[0164] When the electronic device 20 is assembled with the protective shell 10, the back of the electronic device 20 is attached to the bottom wall 114 of the shell body 11, and the side of the electronic device 20 is attached to the side wall 113 of the shell body 11.

[0165] In one application scenario, the opening 101 is located on the side wall 113, at least one function key 21 of the electronic device 20 is located on the side surface, and the first button part 13 is located at the opening 101.

[0166] In one application scenario (not shown), the opening 101 is located on the bottom wall 114, and at least one function key 21 of the electronic device 20 is located on the back. The first button part 13 is located at the opening 101, so that the user can directly press the first button part 13 at the opening 101 on the bottom wall 114 of the shell body 11 to control the function key 21.

[0167] In some embodiments, such as Figure 12 As shown, Figure 12 This is a schematic diagram of another embodiment of the shell body of this application. The opening 101 is located on the side wall 113 and the opening 101 penetrates the side of the side wall 113 away from the bottom wall 114.

[0168] Wherein, opening 101 is an open opening 101. For example, in an 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 away from the bottom wall 114 of the shell body 11. Opening 101 is provided on the side wall 113 and the opening 101 penetrates through the second side wall 113 of the shell body 11, forming an open opening 101, so that the edge of the side wall 113 of the shell body 11 forms a notch.

[0169] In some embodiments, such as Figure 2 As shown, the opening 101 is located in the middle region of the sidewall 113, so that the sidewall 113 surrounds the opening 101.

[0170] The opening 101 is a closed opening. The shell body 11 with greater rigidity surrounds the opening 101, which can increase the connection area between the flexible connecting part 12 and the shell body 11, improve the connection stability between the flexible connecting part 12 and the shell body 11, and thus improve the connection stability between the first button part 13 and the shell body 11.

[0171] In some embodiments, when the electronic device 20 is assembled inside 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 part of the outer peripheral area of ​​the function key 21.

[0172] To further improve the user's button experience, in some embodiments, such as Figure 13 As shown, Figure 13 This is a schematic diagram of the structure of an embodiment of the first button part of this application. The first button part 13 includes a button body 131 and an elastic body 132 surrounding the outer periphery of the button body 131. The elasticity of the button body 131 is greater than that of the elastic body 132, so as to increase the rebound force on the button body 131 through the elastic body 132, making the pressing and rebound feedback of the first button part 13 clearer.

[0173] In one application scenario, the elastomer 132 achieves a full-encirclement around the first button portion 13, improving the overall stability and durability of the button; in another application scenario (not shown), the elastomer 132 achieves a partial encirclement around the first button portion 13, such as a semi-encirclement or intermittent encirclement.

[0174] The beneficial effect of the above-mentioned design is that the combination design of the button body 131 and the elastic body 132 can improve the elasticity of the first button part 13 when it is pressed, and improve the user's button feel.

[0175] In other embodiments, the first button portion 13 includes a button body 131 and an elastic body 132 disposed on the button body 131. When the protective shell 10 and the electronic device 20 are assembled, the elastic body 132 is located on the side of the button body 131 closer to the electronic device 20, which can improve the rebound effect of the first button portion 13 when it is pressed.

[0176] The elastomer 132 can work together with the flexible connector 12 to realize the press-and-rebound function of the first button part 13. In a specific embodiment, the flexible connector 12 connects the first button part 13 and the protective shell 10; the elastomer 132 is connected to the flexible connector 12; furthermore, the elastomer 132 can be tightly connected to the flexible connector 12 through a hot pressing process.

[0177] In some embodiments, the flexible connection portion 12 may be absent, and an elastomer 132 may be used to connect the first button portion 13 and the housing body 11 to realize the press-and-rebound function of the first button portion 13.

[0178] In some embodiments, such as Figure 14 As shown, Figure 14 This is a schematic diagram of the structure of an embodiment of the button body of this application. The button body 131 includes a third flexible layer 303, a fiber layer 42 and a fourth flexible layer 304 stacked sequentially along the thickness direction z.

[0179] 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 sequentially stacked. This stacked structure can improve the structural strength of the button body, and can shape the fiber layer 42, preventing deformation of the fiber layer 42 and preventing the fiber bundles that form the fiber layer 42 from loosening and dispersing. 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 projection of the third flexible layer 303 and the fourth flexible layer 304 along the thickness direction z of the shell body 11 covers the fiber layer 42 to improve the positioning effect.

[0180] 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 in the figure), the projection sizes of the three can also be set to be different, 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, etc.

[0181] Furthermore, the stiffness of the fiber layer 42 is greater than that of the third flexible layer 303 and the fourth flexible layer 304. In this way, while effectively protecting the fiber layer 42, the plastic deformation capacity of the entire first button portion 13 is improved, preventing the first button portion 13 from deforming after long-term use.

[0182] In some embodiments, the elastomer 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.

[0183] TPU elastic rings possess excellent wear resistance and tear resistance, maintaining good elasticity and stability over long-term use. Available in transparent or dark black, TPU rings are not only aesthetically pleasing but also match the colors of various electronic device casings, enhancing the overall visual appeal. The high resilience of TPU elastic rings effectively cushions button pressure, extending their lifespan. TPU elastic rings are adaptable to various environments and are not prone to aging. Furthermore, the lightweight nature of TPU material reduces the burden on devices, improving portability.

[0184] Understandably, the elastomer 132 can also be formed from other types of highly elastic polymer materials in the prior art, such as silicone or rubber.

[0185] The third flexible layer 303 and the fourth flexible layer 304 are both TPU films. TPU films have excellent properties such as good transparency, good formability, high melting point, and good adhesion to other film layers. They can reduce the difficulty of the molding process, improve reliability and aesthetics, and enhance the visibility and texture of the fiber layer 42. Therefore, by choosing TPU films as the third flexible layer 303 and the fourth flexible layer 304, the appearance of the button body 131 can be improved simply by modifying the color and appearance of the fiber layer 42, which can improve the convenience of production design.

[0186] Among them, aramid fiber has properties such as high strength, high modulus, high temperature resistance, and corrosion resistance, which can effectively improve the structural strength and durability of the button body 131, ensuring stable performance even under frequent pressing. Its lightweight and soft characteristics can further optimize the tactile feel and rebound effect of the button, enhancing the user experience.

[0187] In some embodiments, the fiber layer 42 can increase the flexibility of the button body 131 and improve its fit with the button 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 prior art.

[0188] In some embodiments, the fiber layer 42 comprises a composite layer of aramid fibers and TPU. The aramid fibers, pre-impregnated with a thermoplastic resin (e.g., polyurethane), are used as the fiber layer 42 after molding, or a laminate of aramid fabric fibers and TPU is used as the fiber layer 42.

[0189] The fiber layer 42 can also be pre-impregnated with epoxy resin. Pre-impregnated aramid fiber layers reduce the material's flexibility and improve its stiffness, wear resistance, impact resistance, and other physical properties. Alternatively, the fiber layer can be left unimpregnated with epoxy resin to maintain its softness. All of the above treatments fall within the scope of this invention.

[0190] To improve the sensitivity of a user's conductive object when operating the sensor button 211 of the electronic device 20 via the first button section 13, the first button section 13 may be improved as follows. In some embodiments, such as Figure 15 As shown, Figure 15 This is a schematic diagram of another embodiment of the protective shell structure of this application. The first button part 13 includes a conductive layer 50, the outer side of the conductive layer 50 is covered by the flexible connection part 12, and the conductive layer 50 is located at least at the opening 101.

[0191] It should be noted that, in this application, the inner side and inner surface of the first button part 13 and its related structures refer to the side of the protective shell 10 that is close to the electronic device 20 when the electronic device 20 is mounted on it, and the outer side and outer surface of the first button part 13 and its related structures refer to the side of the protective shell 10 that is away from the electronic device 20 and close to the conductive body such as the user when the electronic device 20 is mounted on it.

[0192] 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 capacitance between the user's finger and the sensing button 211.

[0193] In the assembled state of the protective shell 10 and the electronic device 20, the conductive layer 50 is positioned close to the electronic device 20, and its outer surface is covered by the flexible connecting portion 12. The outer surface of the conductive layer 50 being covered by the flexible connecting portion 12 means that the flexible connecting portion 12 completely covers the conductive layer 50 along the thickness direction z of the shell body 11 projected towards the electronic device 20. In one application scenario, when a user or other conductive object operates the sensing button 211 of the electronic device 20 via the first button portion 13, the conductive object and the conductive layer 50 are separated by the flexible connecting portion 12. This allows coupling capacitance to 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, thus forming a series capacitance to achieve capacitive sensing. Furthermore, the flexible connecting portion 12 has a conductive layer 50 on the side facing away from the conductive object and closer to the sensing button 211. The proximity of the conductive object to the sensing button 211 increases the conductivity of the inner surface of the first button portion 13, improving the user's sensitivity to the sensing button 211.

[0194] In some embodiments, such as Figure 15 As shown, the first button part 13 also includes a first body layer 61, which is disposed on the outside of the conductive layer 50, and the outer side of the first body layer 61 is covered by the flexible connection part 12.

[0195] The first button portion 13 includes at least a first body layer 61 and a conductive layer 50. In the assembled state of the protective shell 10 and the electronic device 20, the conductive layer 50 is positioned close to the electronic device 20, and the first body layer 61 is disposed on the outer surface of the conductive layer 50. The outer surface of the first body layer 61 is further covered by the flexible connecting portion 12. In one application scenario, the flexible connecting portion 12 completely covers the first body layer 61 along the thickness direction z of the shell body 11 projected toward the electronic device 20. Specifically, the first body layer 61 can be made of wear-resistant materials such as aramid fiber or aramid fiber impregnated with thermoplastic resin.

[0196] The first body layer 61 is disposed between the flexible connection portion 12 and the conductive layer 50. The first body layer 61 can protect the conductive layer 50, and the addition of the first body layer 61 can increase the structural strength of the first button portion 13, preventing the conductive layer 50 from being worn or damaged due to long-term use.

[0197] In some applications, the outer surface 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 shell body 11 toward the electronic device 20 completely covers the conductive layer 50. This arrangement can further improve the protective effect of the first body layer 61 on the conductive layer 50. Furthermore, when the flexible connection part 12 is made of transparent material, the conductive layer 50 can be visually covered by the first body layer 61. Improving the first body layer 61 can improve the appearance of the first button part 13, thus improving the convenience of production design.

[0198] 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.

[0199] In some embodiments, such as Figure 16 As shown, Figure 16 This is a schematic diagram of the structure of an embodiment of the first body layer of this application. The first body layer 61 includes a third flexible layer 303, a fiber layer 42 and a fourth flexible layer 304 stacked sequentially along the thickness direction z.

[0200] 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 sequentially stacked. This stacked structure can improve the structural strength of the first body layer 61 and can shape the fiber layer 42, preventing it from deforming or loosening. 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 flexible layer 303 and the fourth flexible layer 304 along the thickness direction z of the shell body 11 cover the fiber layer 42 to improve the positioning effect.

[0201] 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 in the figure), the projection sizes of the three can also be set to be different, 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, etc.

[0202] 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.

[0203] The third flexible layer 303 and the fourth flexible layer 304 are both second TPU film layers. The specific implementation method and working principle of the second TPU film layer can be referred to the first TPU film layer, and will not be repeated here.

[0204] In one application scenario, aramid fibers, with their high strength, high modulus, high temperature resistance, and corrosion resistance, can effectively improve the structural strength and durability of the button body 131, ensuring stable performance even under frequent pressing. Their lightweight and soft properties further optimize the button's tactile feel and rebound, enhancing the user experience.

[0205] To improve the sensitivity and user experience of a user operating the sensor button 211 of the electronic device 20 via the first button portion 13, the conductive layer 50 of the first button portion 13 can be improved. In some embodiments, the conductive layer 50 includes a conductive film layer 51.

[0206] The conductive film layer 51 refers to a thin film of conductive material with a relatively thin thickness. This reduces the physical barrier between the user's finger and the sensor button 211 of the electronic device 20, making the feedback more intuitive and the touch more sensitive when the user presses or slides the first button 13. Secondly, the conductive film layer 51 has a flexible property similar to a thin film, which allows it to fit more closely to the deformation of the flexible connection when the user slides or presses, avoiding a stiff feel or delayed feedback due to excessive rigidity.

[0207] The conductive film layer 51 can improve the tactile sensation when the user presses or slides the first button 13.

[0208] In some embodiments, the conductivity of the conductive film layer 51 is from 10^6 Ω to 10^12 Ω.

[0209] Higher conductivity affects the accuracy of touch input; conversely, if conductivity is too low, the sensitivity of the sliding operation will be affected when the user slides on the first button section 13 to control the sensor button 211 of the electronic device 20. Therefore, setting the conductivity to be greater than or equal to 10^6 Ω and less than or equal to 10^12 Ω can improve touch accuracy and the sensitivity of the sliding operation. For example, conductivity settings of 10^6 Ω, 10^7 Ω, 10^8 Ω, 10^9 Ω, 10^10 Ω, 10^11 Ω, or 10^12 Ω are possible.

[0210] In some embodiments, the conductive film layer 51 is a TPU conductive film layer 51. The TPU conductive film layer is a conductive film layer composed of TPU material and conductive fillers (such as conductive carbon nanotubes, conductive graphene, conductive silver nanowires, etc.). The TPU conductive film layer 51 has excellent conductivity, wear resistance, flexibility, hydrolysis resistance, and weather resistance, as well as good processing performance and environmental friendliness. It can maintain stable performance in various environments and is easy to manufacture and process.

[0211] To improve the sensitivity and user experience of a user operating the sensor button 211 of the electronic device 20 via the first button portion 13, the first button portion 13 and the flexible connection portion 12 can be improved as follows. In some embodiments, the conductive layer 50 includes a conductive film layer 51; such as Figure 17 As shown, Figure 17 This is a schematic diagram of another embodiment of the protective shell structure of this application. The flexible connection part 12 has a double-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 sequentially, 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.

[0212] This layered arrangement can further improve the structural strength of the first button part 13; the conductive film layer 51 can enhance the button response speed and tactile feel.

[0213] The first flexible layer 301 is positioned to cover the outer side of the third flexible layer 303, and the second flexible layer 302 is positioned to cover the inner side of the conductive film layer 51. That is, the projection of the first flexible layer 301 and the second flexible layer 302 along the thickness direction z of the shell body 11 completely covers the first body layer 61 and the conductive layer 50. This can improve the overall protection of the flexible connection part 12 (i.e., the first flexible layer 301 and the second flexible layer 302) for the first button part 13 (i.e., the first body layer 61 and the conductive layer 50) and improve the positional stability of the first button part 13.

[0214] 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 in the figure), the projection sizes of the three can also be set to be different, 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, etc.

[0215] In some embodiments, such as Figure 17 As shown, the first body layer 61 also includes a fourth flexible layer 304, which is stacked between the conductive film layer 51 and the fiber layer 42.

[0216] By adding a 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 of the conductive film layer 51 bonded to the fiber layer 42 are different from the hot pressing parameters of the fiber layer 42 bonded to 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 stacking. Then the conductive film layer 51 is attached.

[0217] This layered arrangement can further improve the structural strength of the first button part 13; the conductive film layer 51 can enhance the button response speed and tactile feel.

[0218] In one application scenario, the fourth flexible layer 304 is stacked 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.

[0219] To improve the sensitivity and user experience of a user operating the sensor button 211 of the electronic device 20 via the first button portion 13 using a conductive material, the first button portion 13 and the flexible connection portion 12 may be improved as follows. In some embodiments, such as Figure 18 As shown, Figure 18This is a schematic diagram of another embodiment of the protective shell structure of this 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 sequentially along the thickness direction z; the flexible connection part 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 sequentially. 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 outer periphery of the opening 101 on the shell body 11.

[0220] In this configuration, the first flexible layer 301 covers the outer side of the third flexible layer 303, and the conductive film layer 51 covers the inner side 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 enable the protection and positioning of the first body layer 61.

[0221] Furthermore, the conductive film layer 51 extends to the outer periphery of the opening 101 on the shell body 11, enabling the conductive film layer 51 to connect with the outer periphery of the opening 101. This improves the positional stability of the conductive film layer 51, and the first body layer 61 can be further connected to the outer periphery 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. This improves the molding efficiency and the reliability of the protective shell 10 after molding.

[0222] In other embodiments, when the conductive layer 50 is a circuit board or other structure, a similar structural layout as the conductive film layer 51 described above can be adopted to achieve the stacked arrangement of the first body layer 61, the flexible connection portion 12, and the conductive layer 50, so as to improve the first button portion 13 and the flexible connection portion 12.

[0223] 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).

[0224] The advantage of the circuit board lies in its structural design, which enables it to accurately identify the touch position of a user or other conductive object on the first button 13, thereby further improving touch accuracy. For example, in one application scenario, the circuit board, by designing a capacitor array or capacitive sensing area, can accurately identify the touch position by sensing changes in the electric field when the user touches it, and further improve touch accuracy by capacitively sensing the function key 21 of the electronic device 20 through the circuit board.

[0225] In some embodiments, such as Figure 19 As shown, the conductive layer 50 includes a plurality of conductive regions 521 that are insulated along a first direction x; wherein, the first direction x is the length direction of the first button portion 13.

[0226] 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 the vertical plane of the thickness direction z of the housing body 11. Users can slide and touch the first button portion 13 along its length direction. A specific insulation layout design can precisely improve the conductive layer 50's ability to capture and recognize the specific touch positions of conductive objects such as the user, thereby improving the control accuracy when the user controls the sensor button 211 of the electronic device 20 through the first button portion 13.

[0227] The first button section 13 contains segmented conductive areas 521. After the electronic device 20 is mounted on the protective shell 10, the first button section 13 approaches or contacts the sensing button 211. When the user touches the first button section 13 with a conductive body, the conductive areas 521 form coupling capacitors between themselves and the conductive body (human body) and between themselves and the sensing button 211. These two coupling capacitors can be considered to be connected in series, thus forming a series capacitor between the conductive body and the sensing button 211. During the movement of the conductive body along the first direction x, it will sequentially form series capacitors with the segmented conductive areas 521. In actual use, when the user slides their finger, the finger (or conductive body) forms a series capacitor with the corresponding conductive area 521. The chip accurately identifies and positions the finger by sensing the capacitance change at the corresponding position.

[0228] Furthermore, the flexible connection part 12 facilitates the transmission of pressure from the conductive body to the sensing button 211, thereby enabling the pressing of the sensing button 211 and the pressing operation of the sensing button 211.

[0229] For example, in one application scenario, multiple conductive areas 521 are spaced apart to achieve insulation. In other application scenarios, an insulating strip can be set between adjacent conductive areas 521, such as using high-resistance insulating ink (e.g., UV insulating ink, epoxy resin, silicone coating) to form an insulating strip, effectively improving the accuracy of touch signal recognition during use. Insulation can also be achieved through other methods in other application scenarios.

[0230] In some embodiments, such as Figure 19 As shown, the conductive layer 50 has a multilayer structure. 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 element (not shown) disposed in a through hole 525 in the insulating layer 524.

[0231] The circuit board is constructed by stacking a first conductive layer 522, an insulating layer 524, and a second conductive layer 523 in sequence. The first conductive layer 522 and the second conductive layer 523 are electrically connected through a via 525 in the insulating layer 524, eliminating the need for additional wiring. This simple structure reduces the size of the circuit board.

[0232] The first conductive layer 522 and the second conductive layer 523 include a plurality of conductive regions 521 that are insulated along the first direction x. One conductive region 521 located in the first conductive layer 522 and the corresponding other conductive region 521 located in the second conductive layer 523 are electrically connected through a conductive element in a via 525.

[0233] In some application scenarios, refer to Figure 19 The 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 correspond one-to-one and overlap.

[0234] 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 spacer regions on the conductive layers, ensuring that each conductive region 521 is insulated from each other. Furthermore, the conductive regions of the first conductive layer 522 and the conductive regions of the second conductive layer 523 are arranged in a one-to-one correspondence and overlap along the thickness direction z. This allows for precise control of the shape and spacing of the conductive regions 521, optimizing touch signal recognition.

[0235] In some embodiments, the conductive layer 50 further includes a second insulating layer 5242 disposed on the side of the first conductive layer 522 facing away from the insulating layer 524, and a third insulating layer 5243 disposed on the 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 respectively protect the first conductive layer 522 and the second conductive layer 523, enhancing the durability and stability of the conductive layer 50. Through this stacked design, the conductive layer 50 maintains a compact structure while improving touch accuracy and operational reliability.

[0236] In some embodiments, one or more of the insulating layer 524, the second insulating layer 5242, and the third insulating layer 5243 may be flexible insulating layers, such as PI film, PET film, PEN film, etc. The first conductive layer 522 and the second conductive layer 523 may be copper foil structures or graphene film structures.

[0237] Insulating material can be actively filled into adjacent conductive regions 521, or the insulating layer can be filled into the gap between adjacent conductive regions 521 during hot pressing.

[0238] In the above embodiments, a combination of a conductive layer and a fiber layer is used, which solves the technical problem of insensitive touch control through the fiber layer due to its poor conductivity.

[0239] In some embodiments, the first body layer 61 includes a rigid fiber layer, which may be fibers impregnated with a thermosetting resin.

[0240] In one application scenario, the rigid fiber layer can be formed from 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 less prone to loosening or deformation.

[0241] In some embodiments, the rigid fiber layer comprises a composite layer of aramid fibers and a thermosetting resin. The aramid fibers, pre-impregnated with a thermosetting resin (e.g., epoxy resin), serve as the rigid fiber layer after molding. In other embodiments, the material of the rigid fiber layer can also be man-made fibers such as carbon fiber and glass fiber, or metals, rigid plastics, or inorganic materials such as silicon compounds.

[0242] In some embodiments, such as Figure 20 As shown, Figure 20This is a schematic diagram of another embodiment of the protective shell structure of this application. The first body layer 61 includes a rigid fiber layer, and the flexible connection part 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 rigid 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 rigid fiber layer, and the second flexible layer 302 covers the inside of the conductive layer 50.

[0243] The first flexible layer 301 covers the outer side of the rigid fiber layer, and the second flexible layer 302 covers the inner side of the conductive layer 50, thus protecting the rigid fiber layer and the conductive layer 50 and improving structural strength. This covering design also increases the connection area between the first flexible layer 301 and the second flexible layer 302 and the rigid fiber layer and the conductive layer 50, improving connection stability and consequently enhancing the positional stability of the first button portion 13 when pressed. Optionally, the rigid fiber layer is formed by impregnating aramid fibers with epoxy resin.

[0244] In other embodiments, when the conductive layer 50 is a conductive film layer 51 or other structures, a similar structural layout as described above can be adopted to achieve the stacked arrangement of the rigid fiber layer, the first flexible layer 301, the second flexible layer 302, and the conductive layer 50.

[0245] In other embodiments, when the first body layer 61 includes a fiber layer, a structural layout similar to the rigid fiber layer described above can be adopted to achieve the stacked arrangement of the fiber layer, the fourth flexible layer 304, the first flexible layer 301, and the conductive layer 50.

[0246] The second flexible layer 302 inside the conductive layer 50 can also improve or reduce the marks left on the conductive layer 50 due to long-term contact with the function key 21 of the electronic device 20.

[0247] In some embodiments, such as Figure 21 As shown, the first button part 13 includes a fiber layer 42, and the flexible connection part 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 outer peripheral area of ​​the opening 101.

[0248] In some embodiments, the projections of the first flexible layer 301 and the second flexible layer 302 both cover the first opening 1011 and its peripheral region, and the second opening 1012 and its peripheral region.

[0249] The projections of the first flexible layer 301 and the second flexible layer 302 cover the opening 101 and its outer periphery, enabling the connection and fixation of the first flexible layer 301, the second flexible layer 302, and the outer periphery of the opening 101. Furthermore, the first flexible layer 301, the fiber layer 42, and the second flexible layer 302 are stacked sequentially, allowing the fiber layer 42 to be positioned through the first flexible layer 301 and the second flexible layer 302, reducing the risk of positional displacement of the fiber layer 42 during the molding process. The first flexible layer 301 and the second flexible layer 302 also provide protection for the fiber layer 42.

[0250] 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, so as to further improve the protection and positioning effect of the fiber layer 42.

[0251] In some embodiments, such as Figure 22 As shown, Figure 22 This is a schematic diagram of another embodiment of the protective shell structure of this application. The fiber layer 42 is disposed in the first opening 1011. Along the thickness direction z, the first flexible layer 301 is located on the side of the first support layer 111 away from the second support layer 112, and the second flexible layer 302 is located between the first support layer 111 and the second support layer 112. Both the first flexible layer 301 and the second flexible layer 302 extend to the outer peripheral area of ​​the first opening 1011.

[0252] This configuration can improve the positional stability of the first flexible layer 301 and the second flexible layer 302 through the first support layer 111 and the second support 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 part 13 when it is pressed.

[0253] The first flexible layer 301 and the second flexible layer 302 can also be configured in other ways. For example, in some embodiments, such as... Figure 23 As shown, Figure 23 This is a schematic diagram of another embodiment of the protective shell structure of this application. The fiber layer 42 is disposed in the second opening 1012. Along the thickness direction z, the first flexible layer 301 is located on the side of the second support layer 112 away from the first support layer 111, and the second flexible layer 302 is located between the first support layer 111 and the second support 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 outer peripheral area of ​​the second opening 1012.

[0254] For example, in some embodiments, such as Figure 21 As shown, the first flexible layer 301 and the second flexible layer 302 are located between the first support layer 111 and the second support layer 112.

[0255] In some embodiments, such as Figure 24 As shown, Figure 24 This is a schematic diagram of another embodiment of the protective shell structure of this application. The first button part 13 includes two fiber layers 42. The flexible connection part 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 disposed in the first opening 1011, and the other fiber layer 42 is disposed in the second opening 1012. Along the thickness direction z, the first flexible layer 301, the first support layer 111, the second flexible layer 302, the second support layer 112, and the fifth flexible layer 305 are stacked sequentially. The first flexible layer 301 and the second flexible layer 302 each cover a fiber layer 42 and extend to the outer periphery of the first opening 1011. The second flexible layer 302 and the fifth flexible layer 305 each cover another fiber layer 42 and extend to the outer periphery of the second opening 1012.

[0256] The fifth flexible layer 305 can be improved by referring to the second flexible layer 302, which will not be elaborated here.

[0257] Specifically, the second flexible layer 302 and the fifth flexible layer 305 are used to position and protect one fiber layer 42, while the first flexible layer 301 and the second flexible layer 302 are used to position and protect the other fiber layer 42. This embodiment uses a dual-body layer and a dual-rigid layer to achieve the protective shell 10, which improves the overall rigidity of the protective shell 10. Furthermore, the two fiber layers 42 are located within the openings 101 of their respective rigid layers, reducing the overall thickness. The aforementioned positioning film layer reduces the risk of positional displacement of the body layer during the molding process, thereby improving molding efficiency and the reliability of the molded protective shell 10.

[0258] To improve the sensitivity and user experience of a user operating the sensor button 211 of the electronic device 20 via the first button portion 13 using a conductive material, the first button portion 13 and the flexible connection portion 12 may be improved as follows. In some embodiments, such as Figure 37 As shown, the first button part 13 includes a third flexible layer 303, a fiber layer 42 and a fourth flexible layer 304. The flexible connection part 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 sequentially.

[0259] In this embodiment, the first button portion 13 includes a third flexible layer 303, a fiber layer 42, and a fourth flexible layer 304, which can prevent the fiber layer 42 from becoming loose and deformed, and facilitates processing. The first button portion 13 is integrally formed with the shell body 11 through the first flexible layer 301 and the second flexible layer 302, which can improve the positional stability of the first button portion 13. For example, the projection of the first flexible layer 301 and the second flexible layer 302 toward the thickness direction of the shell body 11 covers the opening 101 and the outer peripheral area of ​​the opening 101, so as to improve the positioning effect of the first button portion 13.

[0260] To further improve the adaptability of the protective case 10 to various scenarios and enhance the user experience, in some embodiments, such as Figure 25 As shown, Figure 25 This is a schematic diagram of another embodiment of the protective shell structure of this application. The protective shell 10 also includes a second button part 14. The second button part 14 is disposed inside the first button part 13 and located at the opening 101. The second button part 14 is used to perform data communication with the electronic device 20 assembled on the protective shell 10 when triggered by the first button part 13.

[0261] In the assembled state of the protective shell 10 and the electronic device 20, the second button part 14 is disposed inside the first button part 13, that is, the second button part 14 is disposed on the side of the first button part 13 closer to the electronic device 20.

[0262] In one application scenario, a user can trigger a second button 14 by pressing the first button 13, thereby enabling data communication with the electronic device 20 assembled inside the protective case 10 through the operation of the button.

[0263] For example, in one application scenario, when the back of the electronic device 20 has a sensing area, the second button 14 is located at least at the opening 101 and can be triggered by the first button 13. Furthermore, the functional components of the second button 14 extend at least to the corresponding position where the housing body 11 abuts against or is adjacent to the sensing area of ​​the electronic device 20, and in the assembled state, the position of the functional components of the second button 14 corresponds to the position of the sensing area of ​​the electronic device 20. Therefore, by pressing the first button 13, the user can trigger the functional components of the second button 14, thereby enabling data communication with the sensing area on the back of the electronic device 20. For example, the first button 13 can be located on the side wall 113 of the housing body 11, thus eliminating the need for an opening in the bottom wall 114 of the housing body 11 to trigger the sensing area on the back of the electronic device 20. This design improves the flexibility and versatility of waking up or operating the electronic device 20 through the protective case 10, enhancing the user experience.

[0264] For example, in one application scenario, the protective case 10 is provided with multiple openings 101 and multiple corresponding first button sections 13, each first button section 13 corresponding to a different sensor button 211 of the electronic device 20; wherein, at least one first button section 13 has a corresponding second button section 14 disposed on its inner side. This arrangement can further improve the multi-scenario adaptability of the protective case 10, and can improve the flexibility and ease of operation for users to wake up or trigger the electronic device 20 through the protective case 10.

[0265] In some embodiments, the second button portion 14 includes an NFC (Near Field Communication) component.

[0266] The NFC component enables near-field communication. In this way, the user can trigger the NFC function by pressing the first button 13 on the protective case 10, and can communicate with the corresponding component on the electronic device 20 through the NFC component, thereby enabling the user to wake up or operate the electronic device 20.

[0267] NFC is a short-range, high-frequency wireless communication technology that enables contactless interaction between devices through electromagnetic induction coupling. NFC components can be designed as thin sheets, fitting into the curved surface of the protective casing 10 or miniaturized and embedded in the button area. NFC components can be triggered by pressing a physical button or by touch.

[0268] In some embodiments, a user can trigger the NFC function by pressing the first button 13 on the protective case 10, thereby enabling the NFC component to communicate with the electronic device 20 and thus waking up or operating the electronic device 20. Specifically, when the user presses the button, a mechanical switch closes or a sensor detects a pressure signal, which is transmitted to the microcontroller (such as an MCU) inside the protective case 10, triggering an NFC function start command. The electronic device 20 then reads the data sent by the NFC component and executes the corresponding operation. Compared to the independent NFC components in traditional protective cases, in this embodiment, the NFC component is integrated into the button, allowing the NFC function to be triggered when the button is pressed (such as press-to-pay), reducing additional operation steps and improving ease of use. Secondly, compared to normally open NFC components that are constantly in a readable state, the NFC component in this embodiment is activated in a controlled manner, which reduces the frequency of false triggering during non-active operations. At the same time, the press-triggered mechanism provides the NFC function's location awareness through the physical tactile feedback of the button, allowing the user to locate the operating area without visual confirmation, making the operation more convenient and controllable. In addition, this design makes full use of the internal space inside the button, avoiding additional openings or thickening in other areas of the protective case 10, making the overall structure of the protective case 10 more compact.

[0269] In some embodiments, a user can trigger the NFC function by touching the first button portion 13 on the protective case 10. Specifically, the button area (first button portion 13) of the protective case 10 has a built-in capacitive touch sensor. When a user's finger touches the button, the sensor detects a change in capacitance, generates an electrical signal, and transmits the signal to the MCU inside the protective case 10, triggering preset logic (such as activating the NFC function). The electronic device 20 reads the data sent by the NFC component and performs corresponding operations (such as launching an application or connecting to a device). This example does not require physical pressing; a light touch is sufficient to trigger the function, resulting in a more sensitive user experience.

[0270] The second button unit 14 can also use Bluetooth, RFID, ZIGBEE, a combination of the above technologies, or a combination of the above technologies and NFC technology to realize wireless communication functions.

[0271] In some embodiments, such as Figure 26 , 27 As shown, Figure 26 This is a schematic diagram of the structure of an embodiment of the second button part of this application. Figure 27 This is an exploded structural diagram of an embodiment of the protective shell structure of this 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 contacts the electronic trigger 141 under the action of external force, thereby triggering the functional device 142.

[0272] In one example, the electronic trigger 141 is a triggering device used to receive mechanical pressure or capacitance changes and convert them into an electrical signal, connected to the functional device 142 to activate the NFC function. The electronic trigger 141 can be mechanical, such as conductive rubber or a metal spring; it can also be inductive, outputting a pressure threshold signal through a pressure-sensitive layer and signal processing circuitry. Specifically, the electronic trigger 141 is positioned in the thickness direction z of the housing body 11, 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.

[0273] Functional device 142 is an electronic module that performs NFC functions. After receiving a signal from electronic trigger 141, it initiates communication or executes a preset operation. Functional device 142 typically includes a signal input interface connected to the electronic trigger, a logic control unit for determining the trigger condition, and a communication unit for sending preset data to an external card reader.

[0274] The electronic trigger 141 and the functional device 142 can be directly integrated and installed, for example, by soldering the electronic trigger (such as a microswitch or capacitive sensor) and the functional device onto the same PCB; or by designing independent functional modules and embedding them into the reserved slots in the protective shell through mechanical connections such as snap-fits or slide rails, so as to facilitate future maintenance and replacement. The electronic trigger 141 and the functional device 142 can also be installed separately, for example, by placing the electronic trigger and the functional device separately and connecting them through a flexible circuit board (FPC) or ribbon cable to adapt to the curved surface of the shell or moving parts; or by setting magnetic contacts (such as Pogo Pins) on the trigger and the functional device to achieve physical contact and signal conduction through magnetic attraction.

[0275] In one application scenario, when the housing body 11 has a side wall 113 and a bottom wall 114, and the first button 13 is located on the side wall 113, the electronic trigger 141 is located on the side wall 113 of the housing body 11 and corresponds to the first button 13; the functional device 142 is located on the bottom wall 114. It is understood that electronic devices typically have an NFC sensing area on the back. By placing the functional device 142 on the bottom wall 114 of the housing body 11, it corresponds to the NFC sensing area on the back of the electronic device. Therefore, the first button 13 on the side of the housing body 11 can trigger the NFC sensing area on the back of the electronic device 20, improving the flexibility and versatility of waking up or operating the electronic device 20 through the protective case 10, and enhancing the user experience.

[0276] In one application scenario, the electronic trigger 141 includes a circuit board and a switching element, and the functional device 142 includes an FPC coil electrically connected to the circuit board.

[0277] The circuit board can be rectangular, circular, or polygonal in shape to suit the internal space layout of the device. The material can be FR-4 epoxy resin substrate (a standard PCB material) or flexible substrate (such as polyimide, adaptable to bending requirements). The circuit board can employ a two-layer or multi-layer wiring structure to integrate power interfaces, signal processing units (such as MCU chips), and solder pads.

[0278] Depending on the triggering method, the switching element can be selected from tactile switches, membrane switches, pressure sensors, etc. The shape of the switching element can be a miniature surface mount or a cylindrical button. When the user touches the first button, the capacitive sensor detects and outputs a signal, the NFC signal unit receives the signal and sends preset data, and then the mobile phone receives the data and responds. In some scenarios, the user can touch the button to cause NFC to send a Bluetooth pairing command, thereby enabling the mobile phone to automatically connect to other electronic devices. When the user touches the first button, the switch closes and the circuit is connected, activating the NFC function and sending data to the mobile phone, which then receives the data and responds. In some use cases, the user can press the button to cause NFC to send pre-stored payment card information, and the mobile phone then invokes the payment interface.

[0279] In some embodiments, the protective case 10 also has a charging function. In this case, the NFC component can be used to control whether charging is enabled or disabled.

[0280] 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 piezoelectric sensing function, which can generate an electrical signal when pressed, thereby activating the functional device 142.

[0281] The beneficial effect of the above-mentioned settings is that the functional device 142 can be triggered by a simple button operation, making it easy to operate and providing 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 special design of the functional device, users 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.

[0282] In some embodiments, the functional device 142 includes a coil. The coil may be a PCB coil, a Litz wire coil, or an FPC coil.

[0283] Among them, the functional device 142 can be an FPC (Flexible Printed Circuit) coil, which can be connected to the circuit board. The FPC coil is thin, flexible, and can be bent to fit irregular surfaces so that the overall device structure is compact.

[0284] In some embodiments, such as Figure 26 As shown, the second button part 14 also includes a pressing part 143, which is disposed between the NFC component and the first button part 13.

[0285] In this device, the user can indirectly trigger the pressing part 143 by pressing the first button part 13, thereby activating the NFC component and enabling communication with the electronic device 20.

[0286] In some embodiments, such as Figure 26 , 27 As shown, the inner wall of the shell body 11 is provided with a limiting groove 140 that communicates with the opening 101, and the electronic trigger 141 is limited to the shell body 11 through the limiting groove 140.

[0287] Specifically, the bottom of the limiting groove 140 is provided with a through hole communicating with the opening 101. Therefore, pressing the first button part 13 at the opening 101 can directly trigger the electronic trigger 141, thereby triggering the second button part 14. Furthermore, the electronic trigger 141 is limited in 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 the functional device 142 is accurately triggered with each press.

[0288] In some embodiments, such as Figure 26 As shown, the protective shell 10 also includes an encapsulation cover plate 15, which is connected to the side of the electronic trigger 141 away from the first button part 13; the encapsulation cover plate 15 is installed on the inner side wall 113 of the shell body 11 and covers the limiting groove 140.

[0289] The encapsulation cover 15 being installed on the inner wall 113 of the housing body 11 and covering the limiting groove 140 means that the encapsulation cover 15 is located on the side of the protective housing 10 close to the electronic device 20.

[0290] The encapsulation cover 15 provides support for the NFC component, allowing it to move stably along the pressing direction without shifting in other directions. This design effectively improves the positional stability and reliability of the electronic trigger 141. Specifically, the encapsulation cover 15 effectively protects the electronic trigger 141, preventing dust and moisture from entering the limiting groove 140 and ensuring that the electronic trigger 141 maintains efficient response during long-term use.

[0291] To further reduce the size of the protective case 10, similar improvements can be made to the first button portion 13 as described above. For example, in some embodiments, the first button portion 13 includes an NFC component.

[0292] The working principle and specific implementation method of the NFC component can be found in the above embodiments, and will not be repeated here.

[0293] To further improve the user experience when triggering the sensor button 211 of the electronic device 20 via the first button section 13, the first button section 13 can be further improved. In some embodiments, such as Figure 28 As shown, Figure 28This is a schematic diagram of an embodiment of the protective case and electronic device structure of this application. The inner surface of the first button portion 13 is flush with or protrudes inward relative to the inner surface of the outer peripheral region of the opening 101 to form a first protrusion portion 134.

[0294] The inner surface of the first button portion 13 refers to the side of the first button portion 13 closest 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 closest 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, facilitating the user's assembly of the protective case 10 onto the electronic device 20. The inner surface of the first button portion 13 protrudes inward relative to the inner surface of the outer peripheral area of ​​the opening 101, meaning that in the assembled state, the inner surface of the first button portion 13 protrudes towards the electronic device 20, forming a first protrusion 134. The design of the first protrusion 134 reduces the user's button operation time, improves trigger sensitivity, and optimizes the user experience.

[0295] 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 shell 10. When the sensor button 211 of the electronic device 20 is recessed into the side surface of the electronic device 20, the inner surface of the first button portion 13 is designed to bulge inward, forming a first protrusion 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 and reducing the number of button presses, thus improving the ease of operation.

[0296] In some embodiments, the protrusion height H1 of the first protrusion 134 is 0.1 mm to 0.5 mm.

[0297] If the protrusion height is too high, it may cause excessive button feedback, affecting the feel of operation; if the protrusion height is too low, it may not be able to effectively reduce the button press process. Therefore, choosing an appropriate protrusion height, such as 0.1mm, 0.2mm, 0.3mm, 0.4mm, or 0.5mm, can ensure trigger sensitivity while optimizing the user experience.

[0298] In some embodiments, the protrusion height H1 of the first protrusion 134 is 0.2 mm to 0.3 mm.

[0299] The height H1 of the first protrusion 134 is selected within this range, which can further improve the accuracy of operation and the user's button experience.

[0300] In some embodiments, such as Figure 29 As shown, Figure 29This is a cross-sectional structural diagram of an embodiment of the protective shell after the molding process. When the protective shell 10 is equipped with an electronic device 20, the outer surface of the area of ​​the flexible connection portion 12 corresponding to the first button portion 13 protrudes outward relative to the outer surface of other areas of the flexible connection portion 12 to form a second protrusion 135.

[0301] The second protrusion 135 can improve the efficiency and reliability of the recognition of the first button 13, thereby improving the operating efficiency and reliability of the electronic device 20.

[0302] In other embodiments, this can be achieved by recessing the outer surface of the area of ​​the flexible connecting portion 12 corresponding to the first button portion 13 relative to the outer surface of other areas of the flexible connecting portion 12, or by setting the outer surface of the area of ​​the flexible connecting portion 12 corresponding to the first button portion 13 and the shell body 11 to have different textures, colors, reflectivities, etc. For example, surface treatments such as fluorescent treatment can be applied to the outer surface of the area of ​​the flexible connecting portion 12 corresponding to the first button portion 13 so that the user can notice the area of ​​the flexible connecting portion 12 corresponding to the first button portion 13 at first glance.

[0303] In other embodiments, when the flexible connecting portion 12 does not cover the first button portion 13, the outer surface of the first button portion 13 can be recessed or protruded relative to the outer surface of the outer peripheral region of the opening 101. Alternatively, this can be achieved by setting the first button portion 13 and the shell body 11 to have different textures, colors, reflectivities, etc. For example, surface treatments such as fluorescent treatment can be applied to the outer surface of the first button portion 13 to make the user notice the first button portion 13 immediately. In one specific embodiment, a fluorescent agent is added to the material layer of the first button portion 13 to help the user better notice the presence of the first button portion 13 in a dark environment. In this case, the second protrusion 135 can be omitted, and the outer surface of the first button portion 13 can be flush with the outer surface of the outer peripheral region of the opening 101.

[0304] In some embodiments, the protrusion height H2 of the second protrusion 135 is 0 to 0.5 mm. When the protrusion height H2 is 0, it can be understood that the second protrusion 135 is not formed, and the outer surface of the first button portion 13 is flush with the outer surface of the outer peripheral region of the opening 101. For example, the protrusion height H2 can specifically be 0, 0.05 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm.

[0305] In some embodiments, the protrusion height H2 of the second protrusion 135 is 0.1 mm to 0.5 mm.

[0306] The height H2 of the second protrusion 135 is selected within the range of 0.1mm to 0.5mm to ensure the sensitivity of button recognition while avoiding inconvenience caused by excessive protrusion. For example, the height can be specifically 0.1mm, 0.2mm, 0.3mm, 0.4mm or 0.5mm to balance visual effect and tactile feel, further improving the user experience.

[0307] In some embodiments, the protrusion height of the outer side of the overall structure of the flexible connection portion 12 and the first button portion 13 relative to the outer side of the housing body 11 is 0 mm to 0.5 mm. Specifically, the protrusion height can be 0, 0.05 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm.

[0308] To further improve the positional stability of the first button portion 13 and the housing body 11, in some embodiments, such as Figure 5 As shown, the protective shell 10 also includes a first positioning film 316, which is disposed on the outside of the shell body 11 and at least covers the opening 101.

[0309] The first positioning film 316 reduces or prevents contact between the surface material of the shell body 11 (e.g., the first support layer 111 and the second support layer 112) and the first button portion 13 located within the opening 101 during the molding process of the protective shell 10, thus avoiding the problem of the surface of the first button portion 13 becoming brittle and hard, affecting the button's function. Therefore, this embodiment can improve the reliability of the first button portion 13 and the protective shell 10.

[0310] To further improve the positional stability of the first button portion 13 and the housing body 11, in some embodiments, such as Figure 5 As shown, the protective shell 10 also includes a second positioning film 317, which is disposed on the inner side of the shell body 11 and at least covers the opening 101.

[0311] The second positioning film 317 reduces or prevents contact between the surface material of the shell body 11 (e.g., the first support layer 111 and the second support layer 112) and the first button portion 13 located within the opening 101 during the molding process of the protective shell 10, thus avoiding the problem of the surface of the first button portion 13 becoming brittle and hard, affecting the button's function. Therefore, this embodiment can improve the reliability of the first button portion 13 and the protective shell 10.

[0312] In some embodiments, the first button portion 13 is provided with both a first protrusion 134 and a second protrusion 135 to improve the convenience and experience of the user pressing the button.

[0313] In some embodiments, the thicknesses of the first support layer 111 and the second support layer 112 may be different.

[0314] This application further proposes a protective shell 10, in some embodiments, such as Figure 30 As shown, the protective shell 10 includes a shell body 11, a flexible connecting portion 12, and an elastic ring 16. The shell body 11 has an opening 101; the elastic ring 16 is located at the opening 101, and the flexible connecting portion 12 covers the elastic ring 16 and the opening 101. The elastic ring 16 is integrally formed with the shell body 11 through the flexible connecting portion 12; wherein, the stiffness of the shell body 11 is greater than the stiffness of the flexible connecting portion 12.

[0315] There are several ways to achieve a one-piece design. For example, heating or pressurizing can melt the relevant substances in at least two material layers, allowing them to 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 with adhesive or similar materials and then cured. This one-piece design results in at least two material layers forming an inseparable whole without violent intervention; this inseparable whole is also known as a "one-piece integral design."

[0316] In one application scenario, the protective case 10 and the electronic device 20 are in an assembled state. The user can trigger the sensing button 211 of the electronic device 20 corresponding to the opening 101 by pressing the flexible connecting part 12 at the opening 101. Furthermore, pressing the flexible connecting part 12 at the opening 101 can effectively compress the elastic ring 16, thereby enabling the flexible connecting part 12 at the opening 101 to quickly rebound when the user releases the pressure on the flexible connecting part 12.

[0317] In this way, by setting the flexible connecting part 12 to cover the elastic ring 16 and the opening 101, the protective effect of the protective shell 10 on the electronic device 20 can be effectively improved, and the risk of the electronic device 20 being directly exposed to the external environment at the opening 101 can be reduced. Furthermore, by setting the flexible connecting part 12 to cover the elastic ring 16 and the opening 101, the flexible connecting part 12 can be used to achieve the effect of setting buttons on the protective shell 10, which can reduce the thickness of the protective shell 10. Furthermore, the flexible connecting part 12 can form a flexible area at the opening 101. The flexible area is easily deformed under the action of external force, which can reduce the difficulty of disassembling and assembling the protective shell 10 and improve the sensitivity and reliability of external operation on the electronic device 20. Furthermore, the setting of the elastic ring 16 can improve the rebound effect of the flexible connecting part 12 at the opening 101, and improve the user's button experience.

[0318] In some embodiments, improvements to the shell body 11 may also refer to the above embodiments, which will not be repeated here.

[0319] This application further proposes a method for preparing the protective shell 10. In some embodiments, such as... Figure 31 As shown, Figure 31This is a schematic flowchart of an embodiment of the preparation method of the protective shell of this application. The preparation method includes steps S11 to S13.

[0320] Step S11: Prepare the first button part and prepare the shell body, wherein the shell body has an opening.

[0321] 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 openings 101 of corresponding size are set on the bottom wall 114 or side wall 113 of the shell body 11 according to the application scenario.

[0322] Referring to the specific structure of the first button part 13 in the above embodiments, the first button part 13 is prepared by means of bonding or hot pressing using appropriate materials.

[0323] Step S12: The flexible connecting part and the first button part are heat-pressed to obtain the button body.

[0324] In this way, the flexible connecting part 12 and the first button part 13 are fixedly connected.

[0325] Step S13: The shell body and the button body are stacked together to form a flexible connection between the button body and the shell body; wherein, the first button part is located at the opening, and the projection of the first button part is located inside the opening along the thickness direction of the shell body; the rigidity of the shell body is greater than the rigidity of the flexible connection part.

[0326] 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 connecting portion 12 is stacked with the outer periphery of the opening 101 on the shell body 11. The connection between the flexible connecting portion 12 and the shell body 11 is achieved through processes such as hot pressing. This method simplifies the manufacturing process and improves production efficiency.

[0327] 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. (See reference...) Figure 32 The operation of stacking the shell body 11 and the button body in step S13 specifically includes steps S21 to S22.

[0328] Step S21: Stack the first support layer and the button body together so that the button body covers the first opening.

[0329] Step S22: Stack the second support layer on the side of the button body away from the first support layer, so that the button body covers the second opening.

[0330] In this embodiment, at least a portion of the flexible connection portion 12 is stacked between the first support layer 111 and the second support layer 112; the stiffness of both the first support layer 111 and the second support layer 112 is greater than the stiffness of the flexible layer.

[0331] This configuration allows the flexible connecting part 12 to be fixed from both sides via the first support layer 111 and the second support layer 112, thereby improving the stability of the connection between the flexible connecting part 12 and the shell body 11, and further improving the connection stability between the shell body 11 and the button body.

[0332] In some embodiments, step S21 further includes: stacking the first support layer 111 and the button body, such that the button body covers the first opening 1011; and then covering the outside of the first support layer 111 with the first positioning film 316, covering the first opening 1011 of the first support layer 111 and the button body.

[0333] In some embodiments, step S22 further includes: stacking a second support layer 112 on the side of the button body away from the first support layer 111, such that the button body covers the second opening 1012, and then covering the outside of the second support layer 112 with a second positioning film 317; the second positioning film 317 covers the second opening 1012 and the button body.

[0334] The provision of the first positioning film 316 and the second positioning film 317 reduces or avoids contact between the surface material of the shell body 11 (e.g., the first support layer 111 and the second support layer 112) and the first button portion 13 located within the opening 101 during the molding process of the protective shell 10. This prevents the surface of the first button portion 13 from becoming brittle and hard, thus affecting the button's function. Therefore, this embodiment improves the reliability of the first button portion 13 and the protective shell 10.

[0335] In other embodiments, the shell body 11 and the second support layer 112 can be stacked first, and then combined with the first support layer 111 to ensure that the button body firmly covers the opening 101.

[0336] In some embodiments, any one or more of the flexible connection portion 12, the first flexible layer 301, the second flexible layer 302, the third flexible layer 303, the fourth flexible layer 304, and the fifth flexible layer 305 described in the above embodiments can be a film structure made of TPU material. In other embodiments, the materials of the above flexible layers and flexible connection portions can also be silicone, latex, rubber, or other materials.

[0337] The tensile strength of the TPU film structure is 38.5 MPa, as measured by ASTM standards; the ultimate elongation is 600%, as measured by ASTM D412 standards; and the tensile stress at 100% elongation is 11.1 MPa, as measured by ASTM D412 standards. This design improves the elasticity and structural stability of the film structure, thereby enhancing the reliability and service life of the protective shell 10.

[0338] The second positioning film and the flexible layer, or one of them, can be repeatedly provided on the inner side of the shell body; the first positioning film and the flexible layer, or one of them, can be repeatedly provided on the outer side of the shell body.

[0339] Example Group 2

[0340] In some embodiments, a conductive layer 50 may be provided for embodiments that do not have a conductive layer 50 as described above. For specific implementation details, please refer to the embodiments that have a conductive layer 50 described above.

[0341] The protective shell 10 with a conductive structure may also be not limited to the above embodiments.

[0342] In some embodiments, such as Figure 33 As shown, Figure 33 This is a schematic diagram of another embodiment of the protective shell structure of this application. The protective shell 10 includes: a shell body 11; and a conductive part 17, which covers a portion of the shell body 11 and is integrally formed with the shell body 11. When the electronic device 20 is assembled on the protective shell 10, the conductive part 17 covers the buttons of the electronic device 20 along the thickness direction z of the shell body 11.

[0343] like Figure 1 As shown, the housing body 11 defines a receiving cavity 110 for accommodating at least a portion of the electronic device 20; as Figure 33 , 34 As shown, the conductive part 17 includes a flexible connection part 12 and a first button part 13. Specific embodiments of the flexible connection part 12 and the first button part 13 can be found in the above-described embodiments. The button of the electronic device 20 can be a function key 21.

[0344] On the one hand, the shell body 11 can increase the sensitivity of the button operation of the electronic device 20 in this area through the conductive part 17; on the other hand, the conductive part 17 is integrally set with the shell body 11, which can improve the structural stability of the protective shell 10 and improve the protection capability of the electronic device 20; this application improves the sensitivity of button operation through the conductive part 17.

[0345] In some embodiments, the conductive portion 17 covers the inner side of the stated area. This structure allows the conductive portion 17 to be positioned closer to the electronic device 20 when the protective housing 10 and the electronic device 20 are assembled, thereby improving the sensitivity of operation of the electronic device 20. If the conductive portion 17 were on the outside, it might be affected by environmental factors other than fingers (such as humidity, stray capacitance), while the built-in conductive portion 17 can reduce these interferences, making the capacitive coupling more stable.

[0346] In some embodiments, the housing body 11 has an opening 101, and the conductive portion 17 at least covers the opening 101. When the electronic device 20 is mounted on the protective housing 10, the opening 101 is correspondingly positioned to correspond to the button. In this way, the thickness of the housing 10 corresponding to the button position can be protected, and the influence of the high rigidity of the housing body 11 on the button operation can be reduced, thereby improving the control sensitivity of the electronic device 20.

[0347] In some embodiments, such as Figure 34 As shown, Figure 34 This is a schematic diagram of another embodiment of the protective shell structure of this application. The shell body 11 includes: a first support layer 111 with the first opening 1011; a second support layer 112, which is stacked with at least a portion of the first support layer 111 along the thickness direction z, and the second support layer 112 has the second opening 1012. Along the thickness direction z, the first opening 1011 and the second opening 1012 at least partially overlap to form the opening 101; and at least a portion of the conductive part 17 is stacked between the first support layer 111 and the second support layer 112. This arrangement improves the structural stability between the conductive part 17 and the shell body 11. For details regarding the structure of the shell body 11, please refer to the above embodiment.

[0348] In some embodiments, the conductive portion 17 includes a conductive layer 50. Specific implementations of the conductive layer 50 and the connection structure between the conductive layer 50 and the shell body 11 can be found in the above embodiments.

[0349] In some embodiments, such as Figure 34 As shown, the conductive portion 17 further includes a flexible connecting portion 12.

[0363] In some embodiments, such as Figure 3 As shown, the protective case 10 is configured to protect the electronic device 20, which has function keys 21.

Detailed analysis and extensions of this embodiment can be found in the above embodiments.

[0366] The relevant structures and extension schemes in this set of embodiments can be found in the descriptions of the embodiments above.

[0367] Example Group 3

[0368] In some embodiments, a conductive layer 50 may be provided for embodiments that do not have a conductive layer 50 as described above. For specific implementation details, please refer to the embodiments that have a conductive layer 50 described above.

[0369] The protective shell 10 with a conductive structure may also be not limited to the above embodiments.

[0370] In some embodiments, such as Figure 28 As shown, the protective case 10 includes: a case body 11; a first button portion 13 connected to the case body 11, wherein the inner surface of the first button portion 13 protrudes inward relative to the inner surface of the case body 11 to form a first protrusion 134 on the inner side of the case body 11; wherein, when the electronic device 20 is assembled on the protective case 10, the first protrusion 134 covers the button of the electronic device 20 along the thickness direction z of the case body 11.

[0371] The buttons on the electronic device 20 can be function keys 21.

[0372] On the one hand, the first protrusion 134 can shorten the distance between the protective shell 10 and the buttons of the electronic device 20 mounted inside the protective shell 10, or provide interference fit, thus providing timely tactile feedback to the user and improving the sensitivity of the buttons of the electronic device 20 to the external force applied to the shell body 11. On the other hand, compared with the solution of exposing the buttons by providing an opening 101 on the shell body 11 to improve the sensitivity of button operation, this application improves the sensitivity of button operation by reducing the distance between the first button part 13 and the buttons of the electronic device 20 through the first protrusion 134 inside the shell body 11, and the first protrusion 134 covers the buttons of the electronic device 20 to prevent them from being exposed, preventing external substances such as dust and liquid from penetrating into the button area, thereby improving the protection effect of the electronic device 20. In addition, the cover-up design of the first button part 13 over the buttons of the electronic device 20 gives the protective shell 10 an integrated aesthetic. When the electronic device 20 is mounted on the protective shell 10, the appearance of the protective shell 10 is not affected by the appearance of the buttons of the electronic device 20. Thus, the protective shell 10 combines functionality and aesthetics.

[0373] In some embodiments, when the protective housing 10 is assembled with the electronic device 20, the first protrusion 134 is interference-fitted with the button of the electronic device 20. In this way, when the electronic device 20 is assembled inside the protective housing 10, the first button portion 13 abuts against the button of the electronic device 20, thereby achieving pre-pressing of the button and improving the sensitivity of the button operation of the electronic device 20 by the external force applied to the housing body 11.

[0374] In some embodiments, the protrusion height of the first protrusion 134 is 0.1 mm to 0.5 mm. For a detailed analysis and extension of this embodiment, please refer to the above embodiments.

[0375] In some embodiments, the protrusion height of the first protrusion 134 is 0.2 mm to 0.3 mm. For a detailed analysis and extension of this embodiment, please refer to the above embodiments.

[0376] In some embodiments, the first button portion 13 is integrally formed with the housing body 11. In this way, the connection strength between the first button portion 13 and the housing body 11 can be improved, more effectively resisting external impacts and pressures, thereby increasing the structural stability of the protective housing 10 and improving the protective effect of the protective housing 10 on the electronic device 20.

[0377] In one application scenario, the function key 21 of the electronic device 20 is recessed relative to the outer surface of the electronic device 20. Thus, when the protective case 10 is fitted with the electronic device 20, the first protrusion 134 can fit and fill the recess to improve the operating accuracy of the first button portion 13.

[0395] The protective shell 10 with a conductive structure may also be not limited to the above embodiments.

[0396] In some embodiments, such as Figure 25As shown, the protective shell 10 includes: a shell body 11 with an opening 101; a flexible connecting part 12; and a button part 18. The button part 18 is connected to the shell body 11 through the flexible connecting part 12 and is located at the opening 101. Along the thickness direction z of the shell body 11, the projection of the button part 18 is located within the opening 101. The button part 18 communicates with an electronic device 20 assembled in the protective shell 10 under the triggering of an external force. The rigidity of the shell body 11 is greater than the rigidity of the flexible connecting part 12. On the one hand, the button portion 18 located at the opening 101 of the shell body 11 is connected to the shell body 11 via a flexible connecting portion 12 with lower rigidity. This improves the deformation capability of the button portion 18 relative to the shell body 11, enhances the tactile feel of the button portion 18, reduces the impact of the rigid shell body 11 on the operation of the button portion 18, and improves the control sensitivity of the electronic device 20. On the other hand, by providing the button portion 18 at the opening 101 of the shell body 11 and connecting the button portion 18 to the shell body 11 via the flexible connecting portion 12, the sealing of the opening 101 is increased by the button portion 18 and the flexible connecting portion 12, thereby improving the problem of the corresponding button of the electronic device 20 being exposed and not effectively protected. Furthermore, the rigidity of the shell body 11 is greater than that of the flexible connecting portion 12. As the main body of the protective shell 10, the shell body 11 can effectively protect the entire electronic device 20. Moreover, the protective shell 10 communicates with the electronic device 20 via the button portion 18, which improves the ease of operation of the electronic device 20.
