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] Near Field Communication (NFC) is an emerging technology that allows devices (such as mobile phones) to exchange data when they are close to each other. It evolved from contactless radio frequency identification (RFID) and interconnection technologies. By integrating inductive card readers, inductive cards and peer-to-peer communication functions on a single chip, it enables mobile payments, electronic ticketing, access control, mobile identity recognition, anti-counterfeiting and other applications using mobile terminals. Electronic devices such as mobile phones and laptops are usually protected by protective cases. However, the presence of these cases can affect the user's ability to operate the NFC button on the electronic device. Typically, an opening is made in the protective case corresponding to the location of the NFC button on the electronic device to expose the NFC button for user operation. However, this structure results in the NFC button of the electronic device not being effectively protected. Utility Model Content

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

[0004] This application provides a protective case, the protective case comprising: a shell body having a receiving cavity and a first through groove communicating with the receiving cavity, the receiving cavity being used to receive an electronic device; an NFC button being at least partially disposed at the first through groove, used to communicate with the electronic device under external operation; and the NFC button being integrally disposed with the shell body.

[0005] The beneficial effects of this application's technical solution are as follows: the protective case provided by this application has an NFC button, at least partially located within the first through-slot of the case body, facilitating external operation of the NFC button. Under external operation, the NFC button communicates with an electronic device located within the case body; and the NFC button is integrally formed with the case body. In this way, on the one hand, the NFC button is located on the case body, and communication with the electronic device is achieved through this NFC button to control the electronic device. Compared to existing solutions that place the NFC button on the electronic device, this application's solution is not constrained by the protective case's control over the NFC button on the electronic device, thus improving the sensitivity of the electronic device's operation. Furthermore, the data communication between the protective case and the electronic device via the NFC button enhances the ease of operation. On the other hand, the NFC button's location within the first through-slot of the case body, and its integral integration with the case body, increases the sealing and structural stability of the protective case. Compared to existing solutions with openings in the protective case, this application addresses the problem of exposed electronic devices lacking effective protection. Attached Figure Description

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0011] The protective case provided in this application is applicable to a variety of electronic devices. These electronic devices can operate independently of the case and / or in conjunction with it. For example, the protective case can be used on mobile phones, tablets, portable media players, cameras, and other portable electronic devices, providing enhanced protection. Embodiments in this application will be described using a mobile phone as an example, and the protective case will also be described using a mobile phone protective case as an example.

[0012] Example Group 1 In some embodiments, such as Figures 1 to 4 As shown, the protective case 100 includes: a case body 10 and an NFC button 20; the case body 10 forms a receiving cavity 11 and a first through groove 12 communicating with the receiving cavity 11, the receiving cavity 11 being used to receive an electronic device; the NFC button 20 is at least partially disposed at the first through groove 12, and is used to communicate with an electronic device (not shown) under external operation; and the NFC button 20 is integrally disposed with the case body 10.

[0013] The housing body 10 defines a receiving cavity 11 for accommodating at least part of the electronic device. A first through slot 12 communicates with the receiving cavity 11 to provide space for the NFC button 20. When the NFC button 20 is operated externally, the corresponding function of the electronic device can be triggered.

[0014] The NFC button 20 enables near-field communication. In this way, users can trigger the NFC function by pressing the NFC button 20 on the protective case 100, and communicate with corresponding components on the electronic device through the NFC button 20, thereby enabling the electronic device to be woken up or operated.

[0015] NFC is a short-range, high-frequency wireless communication technology that enables contactless interaction between devices through electromagnetic induction coupling. The NFC button 20 can be triggered by pressing a physical button or by touch.

[0016] The receiving cavity 11 is used to house and couple electronic devices. One or more coupling structures may also be provided within the receiving cavity 11 for holding and coupling the electronic devices within the receiving cavity 11. 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 100 and the electronic devices is continuous, ensuring that the protective housing 100 and the electronic devices will not accidentally separate during use. It is further understood that the protective housing 100 and the electronic devices can be coupled in a removable manner, allowing the electronic devices to be removed as needed by the user. Thus, the coupling between the protective housing 100 and the electronic devices is reversible, allowing each to be restored to its state before coupling.

[0017] 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."

[0018] In some embodiments, the NFC button 20 and the housing body 10 are integrally thermoformed. This ensures the connection strength between the NFC button 20 and the housing body 10 while simplifying the manufacturing process and improving production efficiency.

[0019] In some embodiments, the NFC button 20 and the housing body 10 can be injection molded in two colors, which can reduce labor and logistics costs and avoid tolerance accumulation caused by separate assembly.

[0020] In this way, on the one hand, an NFC button 20 is provided on the main body 10 of the protective case 100, and the NFC button 20 is used to communicate with the electronic device to control the electronic device. Compared with the existing technical solution of placing the NFC button on the electronic device, this embodiment is not constrained by the protective case 100 to control the NFC button on the electronic device, which can improve the control sensitivity of the electronic device. The protective case 100 communicates with the electronic device through the NFC button 20, which can improve the ease of operation of the electronic device. On the other hand, the NFC button 20 is provided at the first through slot 12 of the main body 10, and the NFC button 20 is integrally set with the main body 10, which can increase the sealing and structural stability of the protective case 100. Compared with the existing technical solution of opening on the protective case, this embodiment can improve the problem of the electronic device being exposed and not effectively protected.

[0021] In some embodiments, such as Figures 4 to 12 As shown, the NFC button 20 includes: a support component 21 and a button body 22; the support component 21 is integrally formed with the housing body 10; the button body 22 is disposed on the support component 21 along the thickness direction D of the housing body 10; wherein, the button body 22 includes a button 221 and a signal generating component 222 located on the side of the button 221 near the receiving cavity 11; the button 221 is used to trigger the signal generating component 222 to generate a magnetic signal under external operation, and the magnetic signal is used to communicate with the electronic device.

[0022] The support component 21 serves as a support structure for the NFC button 20, which can reduce the problem of the button body 22 being not securely installed or being damaged, and can improve the reliability of the NFC button 20 and the protective case 100.

[0023] Button 221 is movably connected to housing body 10 along the thickness direction D, so that button 221 can move along the thickness direction D to trigger signal generating component 222, or de-trigger signal generating component 222.

[0024] The signal generating component 222 includes a switching component (not shown) and an electronic component (not shown). When the user presses button 221, the switching component, such as a mechanical switch, closes or a sensor detects a pressure signal. The signal is transmitted to the electronic component, such as a microcontroller. The microcontroller generates an NFC function activation command, and the electronic device reads the data sent by the NFC button 20 and executes the corresponding operation. Compared with the independent NFC components in traditional protective cases, in this embodiment, the NFC component is integrated into the button, which can trigger the NFC function (such as press payment) when the button is pressed, reducing additional operation steps and improving ease of use. Secondly, compared with normally open NFC components that are constantly in a readable state, the NFC function in this embodiment is activated in a controlled manner, which can reduce the frequency of false triggering during non-active operation. 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 operation area without visual confirmation, making the operation more convenient and controllable.

[0025] It should be noted that, in this application, the thickness direction D of the shell body 10 refers to the thickness direction of the wall portion having the first through groove 12, which can be parallel to the pressing direction of the user's button operation. For example, in one application scenario, the shell body 10 has a side wall (not shown) and a bottom wall (not shown). The side wall is located on the outer periphery of the bottom wall, and the side wall and bottom wall enclose to form a receiving cavity 11. The receiving cavity 11 is configured to accommodate at least a portion of an electronic device. When the first through groove 12 is provided on the side wall, the aforementioned thickness direction D refers to the thickness direction of the side wall of the shell body 10. At this time, the thickness direction D is perpendicular to the side wall, and the pressing direction of the user on the NFC button 20 is perpendicular to the side wall. When the first through groove 12 is provided on the bottom wall, the aforementioned thickness direction D refers to the thickness direction of the bottom wall. At this time, the thickness direction D is perpendicular to the bottom wall, and the pressing direction of the user on the NFC button 20 is perpendicular to the bottom wall.

[0026] In other embodiments, the housing body 10 may include a top wall (not shown), and the top wall, bottom wall and side walls enclose a fully enclosed receiving cavity 11 to completely enclose the electronic device.

[0027] In some embodiments, such as Figures 4 to 12 As shown, the projection of button 221 along the thickness direction D is located within the opening area of ​​the first through groove 12. In this way, the interference of the housing body 10 on the movement of button 221 can be reduced, and the smoothness and feel of button 221 pressing operation can be improved.

[0028] In some embodiments, such as Figures 8 to 10 As shown, the edge of the support component 21 is integrally formed with the shell body 10. In this way, not only can the connection stability between the support component 21 and the shell body 10 be increased, but the connection stability between the NFC button 20 and the shell body 10 can also be improved, thereby increasing the reliability of the protective case 100.

[0029] In some embodiments, such as Figures 10 to 12 As shown, the support component 21 includes: a circuit board 211, and a button body 22 disposed on the side of the circuit board 211 away from the receiving cavity 11.

[0030] The switching components and electronic components can be located on the circuit board 211, or the electronic components can be integrated onto the circuit board 211. For a specific structure, please refer to the NFC module in the relevant technology.

[0031] In some embodiments, such as Figures 8 to 12 As shown, the support assembly 21 further includes: a first support member 212, disposed on the side of the circuit board 211 opposite to the receiving cavity 11, and a signal generating assembly 222 disposed between the first support member 212 and the circuit board 211; the button 221 is movably connected to the first support member 212 along the thickness direction D; the button 221, the signal generating assembly 222, and the circuit board 211 are stacked along the thickness direction D; the first support member 212 is provided with a first clearance slot 213 for the button 221 to move along the thickness direction D to abut against the trigger signal generating assembly 222. The first clearance slot 213 is used to avoid the signal generating assembly 222, so that the button 221 can abut against the trigger signal generating assembly 222.

[0032] On the one hand, the addition of the first support member 212 to the support component 21 can improve its supporting function and enhance the reliability of the NFC button 20 and the protective shell 100. On the other hand, placing the signal generating component 222 between the first support member 212 and the circuit board 211 can improve the protection effect of the signal generating component 222. Furthermore, by using the first support member 212 to limit the button 221, without having to limit the button 221 through the shell body 10, the overall structure of the NFC button 20 can be improved, thus enhancing the stability of the structure.

[0033] In some embodiments, such as Figure 7 , Figure 8 , Figure 9 , Figure 13 and Figure 14 As shown, the first support member 212 is also provided with a second clearance groove 214. Along the thickness direction D, the projection of the first device 202 on the circuit board 211 onto the first support member 212 is located within the second clearance groove 214. The second clearance groove 214 is used to avoid the first device 202 on the circuit board 211, thereby improving the problem of the first support member 212 pressing against the first device 202 on the circuit board 211 and damaging the first device 202.

[0034] In some embodiments, such as Figure 11 and Figure 12As shown, the inner wall of the first clearance groove 213 extends away from the receiving cavity 11 along the thickness direction D to form a guide groove 215, and the button 221 is movably disposed in the guide groove 215 along the thickness direction D. The guide groove 215 can limit the button 221 and the first support member 212, so that the guide groove 215 can move along the thickness direction D, but will not detach from the first support member 212, thereby increasing the reliability of the NFC button 20.

[0035] In some embodiments, such as Figures 4 to 12 As shown, the support assembly 21 also includes a second support member 216, which is disposed on the side of the circuit board 211 near the receiving cavity 11.

[0036] The addition of a second support member 216 to the support component 21 enhances its supporting function and improves the reliability of the NFC button 20 and the protective shell 100. Furthermore, the second support member 216 is located on the side of the circuit board 211 near the receiving cavity 11, which can protect the inner side of the circuit board 211 and the inner side of the signal generating component 222, thereby improving the reliability of the NFC button 20.

[0037] In some embodiments, the first support member 212 and / or the second support member 216 may be selectively provided to reduce the thickness of the support component 21 and the NFC button 20.

[0038] In some embodiments, such as Figure 7 , Figure 8 , Figure 9 , Figure 13 and Figure 14 As shown, the first support member 212 is provided with a first positioning groove 217, and the second support member 216 is provided with a second positioning groove 218. The first positioning groove 217 is used for positioning the first support member 212 with other components and assembly tools such as molds during assembly; positioning is simple and highly accurate. The second positioning groove 218 is used for positioning the second support member 216 with other components and assembly tools such as molds during assembly; positioning is simple and highly accurate.

[0039] In other embodiments, a first positioning groove 217 may be selectively provided on the first support member 212 and / or a second positioning groove 218 may be selectively provided on the second support member 216.

[0040] In some embodiments, such as Figure 8 , Figure 11 , Figure 15 and Figure 16As shown, the NFC button 20 also includes a sealing component 23, forming a sealed area, where at least the signal generating component 222 is disposed. In this embodiment, the sealing component 23 seals at least the signal generating component 222 to improve the situation during the molding process of the protective shell 100, preventing the hot-melt material (e.g., resin) in the shell body 10 from contacting the signal generating component 222 and reducing the impact on the signal generating component 222.

[0041] In some embodiments, such as Figure 8 and Figure 11 As shown, the support assembly 21 includes a circuit board 211 and a first support member 212 stacked along the thickness direction D. The circuit board 211 is disposed on the side of the first support member 212 near the receiving cavity 11. The first support member 212 is provided with a first clearance groove 213 for the button 221 to move along the thickness direction D to abut against the trigger signal generating assembly 222. The sealing assembly 23 includes a rubber ring 231, which surrounds and forms a sealing area and is disposed around the outer periphery of the signal generating assembly 222. The button 221 is at least partially located within the rubber ring 231, which is disposed within the first clearance groove 213. In this embodiment, the signal generating assembly 222 is sealed by the rubber ring 231, which prevents the hot melt material (e.g., resin) in the material of the housing body 10 from contacting the signal generating assembly 222.

[0042] In some embodiments, such as Figure 15 As shown, the sealing component 23 includes a sealing film 232, which covers the outer surfaces of the support component 21 and the signal generating component 222; the sealing film 232 is provided with a first clearance through hole 233 corresponding to the button 221. In this embodiment, the sealing film 232 completely covers the outer surface of the assembly of the support component 21 and the signal generating component 222, which can improve the sealing effect of the signal generating component 222, and the sealing film 232 is relatively thin, which is beneficial to the thin and light design of the NFC button 20.

[0043] In some embodiments, such as Figure 15 As shown, the sealing membrane 232 comprises two layers of thermoplastic polyurethane (TPU) film 234, with the support component 21 and the signal generating component 222 disposed between the two TPU film layers 234. TPU film possesses excellent properties such as good transparency, good formability, high melting point, and good adhesion to other film layers, which can reduce the difficulty of the molding process and improve reliability and aesthetics.

[0044] For example, the sealing membrane 232 can be made of low elastic modulus materials such as TPU, rubber, and silicone.

[0045] In some embodiments, such as Figure 16As shown, the support assembly 21 includes a first support member 212 and a second support member 216 stacked along the thickness direction D. The signal generating assembly 222 is disposed between the first support member 212 and the second support member 216 to form the button assembly 201. The first support member 212 is disposed away from the receiving cavity 11 relative to the second support member 216, and the first support member 212 is provided with a first clearance groove 213 corresponding to the button 221. The sealing assembly 23 includes a sealing adhesive layer 235 disposed on the outer peripheral edge of the button assembly 201.

[0046] In this embodiment, the inner and outer sides of the signal generating component 222 are sealed by the first support member 212 and the second support member 216, and the side edges are sealed by the sealant layer 235. This can prevent hot melt material (such as resin) in the material of the shell body 10 from flowing between the first support member 212 and the second support member 216, thereby affecting the signal generating component 222.

[0047] In some embodiments, such as Figure 16 As shown, the support assembly 21 also includes a circuit board 211, and a signal generating assembly 222 is disposed on the side of the circuit board 211 facing the first support member 212. The signal generating assembly 222 and the circuit board 211 are disposed between the first support member 212 and the second support member 216 to form a button assembly 201. The first support member 212 is disposed away from the receiving cavity 11 relative to the second support member 216, and the first support member 212 is provided with a first clearance groove 213 corresponding to the button 221. The sealant layer 235 is disposed on the outer peripheral edge of the button assembly 201.

[0048] In some embodiments, such as Figure 15 As shown, the support assembly 21 also includes a circuit board 211, and a signal generating assembly 222 is disposed on the side of the circuit board 211 facing the first support member 212. The signal generating assembly 222 and the circuit board 211 are disposed between the first support member 212 and the second support member 216 to form a button assembly 201. The first support member 212 is disposed away from the receiving cavity 11 relative to the second support member 216, and the first support member 212 is provided with a first clearance groove 213 corresponding to the button 221. A sealing film 232 covers the outer surface of the button assembly 201.

[0049] In some embodiments, such as Figure 13 and Figure 14 As shown, the inner wall of the guide groove 215 extends toward the central axis of the guide groove 215 at one end face away from the receiving cavity 11 to form a boss surface 219, so that at least a portion of the button 221 is always limited in the guide groove 215 and will not be dislodged from the first groove 12 by the boss surface 219.

[0050] In some embodiments, such as Figure 13As shown, button 221 is located on the side of the first support member near the receiving cavity 11, and contacts the side of the boss surface 219 near the receiving cavity 11 along the thickness direction D. The corresponding end of button 221 away from the receiving cavity 11 is provided with another boss surface, which overlaps with boss surface 219 along the thickness direction, so that at least a part of button 221 is always limited in the guide groove 215 and will not disengage from the first through groove 12.

[0051] When button 221 is not pressed, button 221 contacts the side of boss surface 219 near receiving cavity 11 along the thickness direction D.

[0052] When assembling the NFC button 20, the button 221 can be placed in the guide slot 215 of the first support member 212, and then the first support member 212 can be assembled with the circuit board 211, etc., to achieve the front assembly of the button 221.

[0053] In some embodiments, the support component 21 is integrally set with the button body 22, which can increase the stability and reliability of the NFC button 20 and the protective shell structure.

[0054] In some embodiments, such as Figure 14 As shown, button 221 is located on the side of the first support member 212 away from the receiving cavity 11, and button 221 extends toward the receiving cavity 11 with mounting foot 223. Mounting foot 223 is provided in the guide groove 215 and connected to the side of the boss surface 219 near the receiving cavity 11. In the unpressed state, button 221 and the side of the boss surface 219 away from the receiving cavity 11 are spaced apart, and the projection along the thickness direction D covers at least a portion of the boss surface 219.

[0055] When assembling the NFC button 20, the assembly of other components of the NFC button 20 can be completed first, and then the mounting foot 223 of the button 221 can be inserted into the guide groove 215 and snapped with the boss surface 219 to realize the subsequent assembly of the button 221.

[0056] In some embodiments, the support component 21 and the shell body 10 are thermoformed. This ensures the connection strength between the support component 21 and the shell body 10 while simplifying the manufacturing process and improving production efficiency.

[0057] In some embodiments, such as Figure 17 As shown, the shell body 10 has a multi-layer structure, and the support component 21 is disposed between two adjacent layers of the multi-layer structure. The support component 21 is sandwiched between two layers of the shell body 10 so that the support component 21 is integrally set with the shell body 10, thereby improving the structural stability of the protective shell 100.

[0058] In some embodiments, the shell body 10 may include two support layers 119. The support layers 119 may be made of aramid fiber material, which is woven from aramid fibers. The aramid fiber material is impregnated with epoxy resin to give it high rigidity and hardness. The two support layers 119 may be formed into the shell body 10 by hot pressing. The shell body 10 may also be made of a high elastic modulus material such as polycarbonate (PC).

[0059] Among them, aramid fibers have high strength, high modulus, high temperature resistance, and corrosion resistance, which can effectively improve the structural strength and durability of the protective shell 100 and ensure stable performance under frequent pressure. The support layer 119 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.

[0060] In some embodiments, such as Figures 10 to 12 As shown, the inner side of the shell body 10 is provided with a mounting groove (not shown) surrounding the outer periphery of the first through groove 12, and the edge of the support component 21 can be set in the mounting groove.

[0061] In some embodiments, the first support member 212 includes a steel sheet, which can improve the support strength and the reliability of the NFC button 20 and the protective case 100.

[0062] In some embodiments, button 221 includes a silicone button to improve the pressing and rebound feel of button 221 and enhance the user experience.

[0063] In some embodiments, such as Figures 4 to 9 As shown, the NFC button 20 also includes a coil 51. When the NFC button 20 is operated externally, the signal generating component 222 can generate an electrical signal, and the coil 51 converts the electrical signal into a magnetic signal. The magnetic signal can trigger the corresponding function of the electronic device.

[0064] In some embodiments, such as Figures 1 to 3 As shown, the shell body 10 is also provided with a camera hole 40 and / or a magnetic attachment 50.

[0065] For further descriptions of this set of embodiments, please refer to other sets of embodiments.

[0066] Example Group 2 In some embodiments, such as Figure 2 , Figure 8 , Figure 11 , Figure 15 and Figure 16As shown, the protective case 100 includes: a case body 10, an NFC button 20, and a sealing assembly 23. The case body 10 forms a receiving cavity 11 and a first through groove 12 communicating with the receiving cavity 11. The receiving cavity 11 is used to receive an electronic device (not shown). The NFC button 20 is disposed on the case body 10. The NFC button 20 includes a button 221 and a signal generating assembly 222 located on the side of the button 221 near the receiving cavity 11. The button 221 is located at the first through groove 12 and is used to trigger the signal generating assembly 222 to generate a signal under external operation. The signal is used to communicate with the electronic device. The sealing assembly 23 forms a sealed area, and at least the signal generating assembly 222 is disposed within the sealed area.

[0067] The housing body 10 defines a receiving cavity 11 for accommodating at least part of the electronic device. A first through slot 12 communicates with the receiving cavity 11 to provide space for the NFC button 20. When the NFC button 20 is operated externally, the corresponding function of the electronic device can be triggered.

[0068] The NFC button 20 enables near-field communication. In this way, users can trigger the NFC function by pressing the NFC button 20 on the protective case 100, and communicate with corresponding components on the electronic device through the NFC button 20, thereby enabling the electronic device to be woken up or operated.

[0069] NFC is a short-range, high-frequency wireless communication technology that enables contactless interaction between devices through electromagnetic induction coupling. The NFC button 20 can be triggered by pressing a physical button or by touch.

[0070] The receiving cavity 11 is used to house and couple electronic devices. One or more coupling structures may also be provided within the receiving cavity 11 for holding and coupling the electronic devices within the receiving cavity 11. 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 100 and the electronic devices is continuous, ensuring that the protective housing 100 and the electronic devices will not accidentally separate during use. It is further understood that the protective housing 100 and the electronic devices can be coupled in a removable manner, allowing the electronic devices to be removed as needed by the user. Thus, the coupling between the protective housing 100 and the electronic devices is reversible, allowing each to be restored to its state before coupling.

[0071] Button 221 is movably connected to housing body 10 along the thickness direction D, so that button 221 can move along the thickness direction D to trigger signal generating component 222, or de-trigger signal generating component 222.

[0072] The signal generating component 222 includes a switching component (not shown) and an electronic component (not shown). When the user presses button 221, the switching component, such as a mechanical switch, closes or a sensor detects a pressure signal. The signal is transmitted to the electronic component, such as a microcontroller. The microcontroller generates an NFC function activation command, and the electronic device reads the data sent by the NFC button 20 and executes the corresponding operation. Compared with the independent NFC components in traditional protective cases, in this embodiment, the NFC component is integrated into the button, which can trigger the NFC function (such as press payment) when the button is pressed, reducing additional operation steps and improving ease of use. Secondly, compared with normally open NFC components that are constantly in a readable state, the NFC function in this embodiment is activated in a controlled manner, which can reduce the frequency of false triggering during non-active operation. 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 operation area without visual confirmation, making the operation more convenient and controllable.

[0073] It should be noted that, in this application, the thickness direction D of the shell body 10 refers to the thickness direction of the wall portion having the first through groove 12, which can be parallel to the pressing direction of the user's button operation. For example, in one application scenario, the shell body 10 has a side wall (not shown) and a bottom wall (not shown). The side wall is located on the outer periphery of the bottom wall, and the side wall and bottom wall enclose to form a receiving cavity 11. The receiving cavity 11 is configured to accommodate at least a portion of an electronic device. When the first through groove 12 is provided on the side wall, the aforementioned thickness direction D refers to the thickness direction of the side wall of the shell body 10. At this time, the thickness direction D is perpendicular to the side wall, and the pressing direction of the user on the NFC button 20 is perpendicular to the side wall. When the first through groove 12 is provided on the bottom wall, the aforementioned thickness direction D refers to the thickness direction of the bottom wall. At this time, the thickness direction D is perpendicular to the bottom wall, and the pressing direction of the user on the NFC button 20 is perpendicular to the bottom wall.

[0074] In other embodiments, the housing body 10 may include a top wall (not shown), and the top wall, bottom wall and side walls enclose a fully enclosed receiving cavity 11 to completely enclose the electronic device.

[0075] On the one hand, an NFC button 20 is provided on the shell body 10 of the protective case 100, and the NFC button 20 is used to communicate with the electronic device to control the electronic device. Compared with the existing technical solution of placing the NFC button on the electronic device, this embodiment is not constrained by the protective case 100 to control the NFC button on the electronic device, which can improve the control sensitivity of the electronic device. The protective case 100 communicates with the electronic device through the NFC button 20, which can improve the ease of operation of the electronic device. On the other hand, the NFC button 20 is provided at the first through groove 12 of the shell body 10, which can increase the sealing performance and structural stability of the protective case 100. Compared with the existing technical solution of opening on the protective case, this embodiment can improve the problem of the electronic device being exposed and not effectively protected. Furthermore, the sealing component 23 seals at least the signal generating component 222, which can improve the situation that the hot melt material (e.g., resin) in the shell body 10 will not come into contact with the signal generating component 222 during the molding process of the protective case 100, reduce the impact on the signal generating component 222, and thus improve the reliability of the protective case 100.

[0076] In some embodiments, such as Figures 4 to 12 As shown, the NFC button 20 includes: a support component 21 and a button body 22; the support component 21 is integrally formed with the housing body 10; the button body 22 is disposed on the support component 21 along the thickness direction D of the housing body 10; wherein, the button body 22 includes a button 221 and a signal generating component 222 located on the side of the button 221 near the receiving cavity 11; the button 221 is used to trigger the signal generating component 222 to generate a magnetic signal under external operation, and the magnetic signal is used to communicate with the electronic device.

[0077] The support component 21 serves as a support structure for the NFC button 20, which can reduce the problem of the button body 22 being not securely installed or being damaged, and can improve the reliability of the NFC button 20 and the protective case 100.

[0078] Button 221 is movably connected to housing body 10 along the thickness direction D, so that button 221 can move along the thickness direction D to trigger signal generating component 222, or de-trigger signal generating component 222.

[0079] In some embodiments, such as Figures 10 to 12 As shown, the support component 21 includes: a circuit board 211, and a button body 22 disposed on the side of the circuit board 211 away from the receiving cavity 11.

[0080] The switching components and electronic components can be located on the circuit board 211, or the electronic components can be integrated onto the circuit board 211. For a specific structure, please refer to the NFC module in the relevant technology.

[0081] In some embodiments, such as Figures 8 to 12 As shown, the support assembly 21 further includes: a first support member 212, disposed on the side of the circuit board 211 opposite to the receiving cavity 11, and a signal generating assembly 222 disposed between the first support member 212 and the circuit board 211; the button 221 is movably connected to the first support member 212 along the thickness direction D; the button 221, the signal generating assembly 222, and the circuit board 211 are stacked along the thickness direction D; the first support member 212 is provided with a first clearance slot 213 for the button 221 to move along the thickness direction D to abut against the trigger signal generating assembly 222. The first clearance slot 213 is used to avoid the signal generating assembly 222, so that the button 221 can abut against the trigger signal generating assembly 222.

[0082] On the one hand, the addition of the first support member 212 to the support component 21 can improve its supporting function and enhance the reliability of the NFC button 20 and the protective shell 100. On the other hand, placing the signal generating component 222 between the first support member 212 and the circuit board 211 can improve the protection effect of the signal generating component 222. Furthermore, by using the first support member 212 to limit the button 221, without having to limit the button 221 through the shell body 10, the overall structure of the NFC button 20 can be improved, thus enhancing the stability of the structure.

[0083] In some embodiments, such as Figures 4 to 12 As shown, the support assembly 21 also includes a second support member 216, which is disposed on the side of the circuit board 211 near the receiving cavity 11.

[0084] The addition of a second support member 216 to the support component 21 enhances its supporting function and improves the reliability of the NFC button 20 and the protective shell 100. Furthermore, the second support member 216 is located on the side of the circuit board 211 near the receiving cavity 11, which can protect the inner side of the circuit board 211 and the inner side of the signal generating component 222, thereby improving the reliability of the NFC button 20.

[0085] In some embodiments, such as Figure 8 and Figure 11As shown, the support assembly 21 includes a circuit board 211 and a first support member 212 stacked along the thickness direction D. The circuit board 211 is disposed on the side of the first support member 212 near the receiving cavity 11. The first support member 212 is provided with a first clearance groove 213 for the button 221 to move along the thickness direction D to abut against the trigger signal generating assembly 222. The sealing assembly 23 includes a rubber ring 231, which surrounds and forms a sealing area and is disposed around the outer periphery of the signal generating assembly 222. The button 221 is at least partially located within the rubber ring 231, which is disposed within the first clearance groove 213. In this embodiment, the signal generating assembly 222 is sealed by the rubber ring 231, which prevents the hot melt material (e.g., resin) in the material of the housing body 10 from contacting the signal generating assembly 222.

[0086] In some embodiments, such as Figure 15 As shown, the sealing component 23 includes a sealing film 232, which covers the outer surfaces of the support component 21 and the signal generating component 222; the sealing film 232 is provided with a first clearance through hole 233 corresponding to the button 221. In this embodiment, the sealing film 232 completely covers the outer surface of the assembly of the support component 21 and the signal generating component 222, which can improve the sealing effect of the signal generating component 222, and the sealing film 232 is relatively thin, which is beneficial to the thin and light design of the NFC button 20.

[0087] In some embodiments, such as Figure 15 As shown, the sealing membrane 232 comprises two layers of thermoplastic polyurethane (TPU) film 234, with the support component 21 and the signal generating component 222 disposed between the two TPU film layers 234. TPU film possesses excellent properties such as good transparency, good formability, high melting point, and good adhesion to other film layers, which can reduce the difficulty of the molding process and improve reliability and aesthetics.

[0088] For example, the sealing membrane 232 can be made of low elastic modulus materials such as TPU, rubber, and silicone.

[0089] In some embodiments, such as Figure 16 As shown, the support assembly 21 includes a first support member 212 and a second support member 216 stacked along the thickness direction D. The signal generating assembly 222 is disposed between the first support member 212 and the second support member 216 to form the button assembly 201. The first support member 212 is disposed away from the receiving cavity 11 relative to the second support member 216, and the first support member 212 is provided with a first clearance groove 213 corresponding to the button 221. The sealing assembly 23 includes a sealing adhesive layer 235 disposed on the outer peripheral edge of the button assembly 201.

[0090] In this embodiment, the inner and outer sides of the signal generating component 222 are sealed by the first support member 212 and the second support member 216, and the side edges are sealed by the sealant layer 235. This can prevent hot melt material (such as resin) in the material of the shell body 10 from flowing between the first support member 212 and the second support member 216, thereby affecting the signal generating component 222.

[0091] In some embodiments, the first support member 212 and / or the second support member 216 may be selectively provided to reduce the thickness of the support component 21 and the NFC button 20.

[0092] In some embodiments, such as Figure 16 As shown, the support assembly 21 also includes a circuit board 211, and a signal generating assembly 222 is disposed on the side of the circuit board 211 facing the first support member 212. The signal generating assembly 222 and the circuit board 211 are disposed between the first support member 212 and the second support member 216 to form a button assembly 201. The first support member 212 is disposed away from the receiving cavity 11 relative to the second support member 216, and the first support member 212 is provided with a first clearance groove 213 corresponding to the button 221. The sealant layer 235 is disposed on the outer peripheral edge of the button assembly 201.

[0093] In some embodiments, such as Figure 15 As shown, the support assembly 21 also includes a circuit board 211, and a signal generating assembly 222 is disposed on the side of the circuit board 211 facing the first support member 212. The signal generating assembly 222 and the circuit board 211 are disposed between the first support member 212 and the second support member 216 to form a button assembly 201. The first support member 212 is disposed away from the receiving cavity 11 relative to the second support member 216, and the first support member 212 is provided with a first clearance groove 213 corresponding to the button 221. A sealing film 232 covers the outer surface of the button assembly 201.

[0094] In some embodiments, the support component 21 is integrally set with the button body 22, which can increase the stability and reliability of the NFC button 20 and the protective shell structure.

[0095] In some embodiments, such as Figure 17 As shown, the shell body 10 has a multi-layer structure, and the support component 21 is disposed between two adjacent layers of the multi-layer structure. The support component 21 is sandwiched between two layers of the shell body 10 so that the support component 21 is integrally set with the shell body 10, thereby improving the structural stability of the protective shell 100.

[0096] In some embodiments, the shell body 10 may include two support layers 119. The support layers 119 may be made of aramid fiber material, which is woven from aramid fibers. The aramid fiber material is impregnated with epoxy resin to give it high rigidity and hardness. The two support layers 119 may be formed into the shell body 10 by hot pressing. The shell body 10 may also be made of a high elastic modulus material such as polycarbonate (PC).

[0097] Among them, aramid fibers have high strength, high modulus, high temperature resistance, and corrosion resistance, which can effectively improve the structural strength and durability of the protective shell 100 and ensure stable performance under frequent pressure. The support layer 119 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.

[0098] In some embodiments, such as Figure 7 , Figure 8 , Figure 9 , Figure 13 and Figure 14 As shown, the first support member 212 is also provided with a second clearance groove 214. Along the thickness direction D, the projection of the first device 202 on the circuit board 211 onto the first support member 212 is located within the second clearance groove 214. The second clearance groove 214 is used to avoid the first device 202 on the circuit board 211, thereby improving the problem of the first support member 212 pressing against the first device 202 on the circuit board 211 and damaging the first device 202.

[0099] In some embodiments, such as Figure 11 and Figure 12 As shown, the inner wall of the first clearance groove 213 extends away from the receiving cavity 11 along the thickness direction D to form a guide groove 215, and the button 221 is movably disposed in the guide groove 215 along the thickness direction D. The guide groove 215 can limit the button 221 and the first support member 212, so that the guide groove 215 can move along the thickness direction D, but will not detach from the first support member 212, thereby increasing the reliability of the NFC button 20.

[0100] In some embodiments, such as Figure 7 , Figure 8 , Figure 9 , Figure 13 and Figure 14As shown, the first support member 212 is provided with a first positioning groove 217, and the second support member 216 is provided with a second positioning groove 218. The first positioning groove 217 is used for positioning the first support member 212 with other components and assembly tools such as molds during assembly; positioning is simple and highly accurate. The second positioning groove 218 is used for positioning the second support member 216 with other components and assembly tools such as molds during assembly; positioning is simple and highly accurate.

[0101] In other embodiments, a first positioning groove 217 may be selectively provided on the first support member 212 and / or a second positioning groove 218 may be selectively provided on the second support member 216.

[0102] In some embodiments, such as Figure 13 and Figure 14 As shown, the inner wall of the guide groove 215 extends toward the central axis of the guide groove 215 at one end face away from the receiving cavity 11 to form a boss surface 219, so that at least a portion of the button 221 is always limited in the guide groove 215 and will not be dislodged from the first groove 12 by the boss surface 219.

[0103] In some embodiments, such as Figure 13 As shown, button 221 is located on the side of the first support member near the receiving cavity 11, and contacts the side of the boss surface 219 near the receiving cavity 11 along the thickness direction D. The corresponding end of button 221 away from the receiving cavity 11 is provided with another boss surface, which overlaps with boss surface 219 along the thickness direction, so that at least a part of button 221 is always limited in the guide groove 215 and will not disengage from the first through groove 12.

[0104] When button 221 is not pressed, button 221 contacts the side of boss surface 219 near receiving cavity 11 along the thickness direction D.

[0105] When assembling the NFC button 20, the button 221 can be placed in the guide slot 215 of the first support member 212, and then the first support member 212 can be assembled with the circuit board 211, etc., to achieve the front assembly of the button 221.

[0106] In some embodiments, the support component 21 is integrally set with the button body 22, which can increase the stability and reliability of the NFC button 20 and the protective shell structure.

[0107] In some embodiments, such as Figure 14As shown, button 221 is located on the side of the first support member 212 away from the receiving cavity 11, and button 221 extends toward the receiving cavity 11 with mounting foot 223. Mounting foot 223 is provided in the guide groove 215 and connected to the side of the boss surface 219 near the receiving cavity 11. In the unpressed state, button 221 and the side of the boss surface 219 away from the receiving cavity 11 are spaced apart, and the projection along the thickness direction D covers at least a portion of the boss surface 219.

[0108] When assembling the NFC button 20, the assembly of other components of the NFC button 20 can be completed first, and then the mounting foot 223 of the button 221 can be inserted into the guide groove 215 and snapped with the boss surface 219 to realize the subsequent assembly of the button 221.

[0109] In some embodiments, such as Figures 10 to 12 As shown, the inner side of the shell body 10 is provided with a mounting groove (not shown) surrounding the outer periphery of the first through groove 12, and the edge of the support component 21 can be set in the mounting groove.

[0110] In some embodiments, the first support member 212 and the second support member 216 both include aluminum sheets, which can improve the support strength and enhance the reliability of the NFC button 20 and the protective case 100. In other embodiments, high-strength materials such as steel sheets can be used instead of aluminum sheets.

[0111] In some embodiments, button 221 includes a silicone button to improve the pressing and rebound feel of button 221 and enhance the user experience.

[0112] In some embodiments, such as Figures 4 to 9 As shown, the NFC button 20 also includes a coil 51. When the NFC button 20 is operated externally, the signal generating component 222 can generate an electrical signal, and the coil 51 converts the electrical signal into a magnetic signal. The magnetic signal can trigger the corresponding function of the electronic device.
