[0058] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0059] See also Figure 1 , Figure 1 This is a schematic diagram of the installation of a key structure in the related art; Figure 1 As shown, in a conventional electronic device, button A is installed at the side opening of the middle frame B. An opening is provided near the side of the middle frame B. The flexible circuit board provided at the tail of button A passes through the opening, penetrates into the interior of the body, and connects to the motherboard in the electronic device, thereby realizing information transmission between the button and the motherboard.

[0060] However, because there is a gap between button A and the middle frame B, external impurities such as moisture and dust will flow along Figure 1 The water inlet path S shown enters the interior of the electronic device, causing damage to the electronic device.

[0061] In view of this, an embodiment of the present disclosure provides a key waterproof module. The key waterproof module proposed in the present disclosure can effectively improve the waterproof performance of the key area.

[0062] See also Figure 2 , Figure 2 This is a schematic diagram of the structure of a key waterproof module according to an exemplary embodiment. Figure 1 ; Among them, the button waterproof module includes:

[0063] The middle frame 1 has an opening slot 11, which is located near the side of the middle frame 1; the button 2 is set on the side of the middle frame 1, and a flexible conductive member 21 is set at the end of the button 2;

[0064] The support platform 3 is arranged in the opening slot 11 and is fixedly connected to the middle frame 1; the flexible conductive member 21 is arranged on the support platform 3 and passes through the notch of the opening slot 11;

[0065] The waterproof component 4 covers the support platform 3 and the flexible conductive member 21 , and seals the notch of the opening slot 11 .

[0066] The key waterproof module proposed in the embodiment of the present disclosure is used in electronic devices to perform waterproof management on the key area where the keys set in the electronic device are located, thereby improving the problem of water vapor from outside the electronic device entering the interior of the electronic device body through the key area, thereby ensuring the safe use of the electronic device.

[0067] Here, the electronic device where the button waterproof module is located includes a fixed terminal, a mobile terminal or a portable device; the fixed terminal includes but is not limited to a vehicle-mounted terminal, a television, etc.; the mobile terminal includes but is not limited to a mobile phone, a tablet computer, etc.; the portable device includes but is not limited to a smart watch, etc., and the embodiments of the present disclosure do not impose further restrictions on this.

[0068] In an embodiment of the present disclosure, the button waterproof module includes a middle frame, the middle frame includes multiple side edges, and a middle frame body connecting the multiple side edges. Functional modules in the electronic device can be set on both the middle frame body and the side edges. For example, the button proposed in the embodiment of the present disclosure can be set in the button opening on the side of the middle frame; multiple functional modules of the electronic device, such as a processing module (such as a central processing unit CPU), a heat dissipation module, a battery module, etc., are set on the middle frame body.

[0069] Here, at least one opening groove is formed on the middle frame body near the side of the middle frame; the opening groove has a preset interval with the side of the middle frame, and the preset interval can provide space for the keys to move; the groove bottom and groove wall of the opening groove are formed by the above-mentioned middle frame body; it should be noted that the opening direction of the opening groove is consistent with the direction of the middle frame toward the screen of the electronic device.

[0070] The keys provided in the embodiments of the present disclosure can be either virtual keys or physical keys, and this disclosure does not impose any restrictions on this. A flexible conductive member is provided at the end of the key. The flexible conductive member is a bendable or flexible conductive member that is conductive and can generate an electrical signal in response to an operation on the key. The electrical signal is then transmitted to a processing module located in the middle frame. Based on the electrical signal, the processing module can activate the function corresponding to the operation on the key.

[0071] Taking the physical button as an example, one end (head) of the physical button is the keycap, which is arranged in the button opening on the side of the middle frame, and the key body is located in the middle frame body. The other end (tail) of the button is connected to the above-mentioned flexible conductive part, a part of the above-mentioned flexible conductive part is located in the above-mentioned opening groove, and the other part passes through the notch of the opening groove and is connected to the processing module.

[0072] In the embodiment of the present disclosure, the above-mentioned physical buttons include but are not limited to fingerprint buttons, power buttons, volume buttons, mute buttons, unlock buttons, etc., and the present disclosure does not impose any restrictions on this.

[0073] In some embodiments, the flexible conductive member includes a flexible circuit board.

[0074] A flexible printed circuit (FPC) is a printed circuit board made of a flexible insulating substrate (such as polyimide or polyester film). The FPC features electronic components and signal traces that connect them. The FPC uses these components and signal traces to respond to keystrokes and generate electrical signals that are transmitted to the processing module.

[0075] Here, FPC has the characteristics of reliability, flexibility, high wiring density, light weight, thin thickness, and good bendability. Therefore, in the embodiment of the present disclosure, setting FPC at the end of the button can not only help the button function to be effectively realized, but also reduce the space occupied by the electronic device and improve the usability of the electronic device.

[0076] In other embodiments, the flexible conductive member further includes a conductive film or a conductive cable.

[0077] In the embodiment of the present disclosure, the support platform can be a structure integrally formed with the middle frame; the support platform can also be a separate structural member, which is fixed in the open groove of the middle frame through an installation process, for example, fixed to the side wall or bottom of the open groove.

[0078] In actual implementation, the embodiment of the present disclosure can be provided with a separate support platform, which is fixed in the opening groove of the middle frame through an installation process. In this way, the structure of the middle frame can be simplified and the difficulty of manufacturing the middle frame can be reduced, especially for light and thin electronic devices, which can effectively improve the efficiency of manufacturing the middle frame.

[0079] Here, the shape of the support platform can be regular or irregular, and the embodiment of the present disclosure does not limit this. For example, in the embodiment of the present disclosure, the support platform can be a cylinder or a cuboid.

[0080] In the embodiments of the present disclosure, the surface of the support platform in contact with the flexible conductive member can be set to a smooth curved surface, so as to reduce damage to the flexible conductive member, such as a flexible circuit board, caused by the bent and protruding position.

[0081] It should be noted that the support platform is arranged in the open groove, which can effectively position and support the flexible conductive member, reduce the problem of insensitive keys caused by misalignment of the flexible conductive member, and improve the effectiveness of the key function.

[0082] In the disclosed embodiment, the waterproof component may be a waterproof coating, a sealing ring, a sealing tape, etc., and is made of a polymer material such as rubber, silicone, polyvinyl chloride, etc. The elasticity and compression deformation of the waterproof component are used to fill the gap inside the opening groove and between the flexible conductive part and the notch of the opening groove, thereby achieving sealing and waterproofing treatment of the empty area of ​​the opening groove, improving the problem of water vapor in the external area flowing into the interior of the fuselage through the opening groove, and thus improving the waterproof performance of the key area.

[0083] The disclosed embodiments provide a waterproof keypad module for keypad areas. The module includes a middle frame, a support platform, and a waterproof assembly. The flexible printed circuit board at the end of the keypad is partially located on the support platform within an opening in the middle frame, while partially extending through the opening of the opening. The waterproof assembly covers the support platform and the flexible conductive member, sealing the opening of the opening. Thus, by providing the waterproof assembly, it is possible to reduce the amount of external moisture that enters the body of the electronic device where the waterproof keypad module is located through the opening, thereby improving the waterproof performance of the keypad area. Furthermore, the support platform and waterproof assembly within the opening can effectively support and position the flexible conductive member, thereby improving the installation stability of the flexible conductive member and reducing the problem of key insensitivity caused by movement of the flexible conductive member, thereby improving the effectiveness of the keypad function.

[0084] In some embodiments, a positioning hole is provided at the bottom of the open slot;

[0085] A positioning piece is provided at the bottom of the support platform;

[0086] The positioning piece is embedded in the positioning hole.

[0087] Here, the support platform is positioned and mounted on the bottom of the open slot by a positioning member provided on the bottom thereof, so that the support platform is matched with a positioning hole on the bottom of the open slot. In other embodiments, the positioning hole may be provided on the slot wall of the open slot, and the positioning member may be provided on the side wall of the support platform, so that the support platform is positioned and mounted on the slot wall of the open slot.

[0088] In some examples, the positioning hole may be a threaded hole, and the corresponding positioning member may be a screw or a threaded column, so that the screw or threaded column can be connected by threads and embedded in the threaded hole.

[0089] In other examples, the positioning hole may be a small hole with a smooth inner wall, and the corresponding positioning member may be a positioning post, which is embedded in the small hole to achieve installation and positioning of the support platform.

[0090] The positioning hole can be a circular hole, and the corresponding positioning post can be a cylinder; the positioning hole can also be a square hole, and the positioning post can be a prism. In other examples, the positioning post can also have an irregular structure. For example, the cross-sectional dimensions of the positioning post at the bottom of the support platform are larger near the bottom of the support platform than away from the bottom of the support platform. In this way, the portion of the positioning post away from the support platform is embedded in the hole, and the portion of the positioning post near the support platform is located outside the hole.

[0091] In the embodiment of the present disclosure, the number of positioning holes and positioning members can be set according to actual needs; the number of positioning holes can be the same as the number of positioning members, or greater than the number of positioning members, thereby improving the installation flexibility of the support platform.

[0092] For example, see Figure 3 and Figure 4 , Figure 3 is a schematic structural diagram of a positioning hole according to an exemplary embodiment; Figure 4 is a schematic structural diagram of a positioning member according to an exemplary embodiment; Figure 3 As shown, on the middle frame 1, two positioning holes 12 are provided at the bottom of the opening slot 11; Figure 4 As shown, two positioning posts 31 are provided at the bottom of the support platform 3 ; the two positioning posts 31 can be respectively embedded in the two positioning holes 12 .

[0093] The embodiment of the present disclosure proposes positioning holes and positioning columns, which can realize the installation and fixation of the support platform in the opening groove; through the effective positioning of the support platform, the position of the above-mentioned flexible conductive part in the opening groove can also be stabilized, thereby improving the structural stability in the key area.

[0094] In some embodiments, combined Figure 4 , the button waterproof module also includes:

[0095] The second adhesive member 32 is located at the bottom of the support platform 3 and is arranged to avoid the positioning member; the second adhesive member 32 is used to bond the support platform 3 and the middle frame ( Figure 4 not shown).

[0096] Here, the second adhesive member may be a foam adhesive or adhesive with double-sided adhesive properties.

[0097] In the embodiment of the present disclosure, the second adhesive member is used to stick the bottom of the support platform and the bottom of the opening groove in the middle frame, so that the support platform can be fixedly installed in the opening groove of the middle frame, thereby solving the problem of misalignment of the flexible conductive member caused by unstable installation of the support platform, thereby ensuring the effectiveness of the key function.

[0098] In some embodiments, see Figure 5 and Figure 6 , Figure 5This is a schematic diagram of the structure of a key waterproof module according to an exemplary embodiment. Figure 2 ; Figure 6 This is a schematic diagram of the structure of the second waterproof member according to an exemplary embodiment. Figure 1 ; Among them, combined Figure 1 、 Figure 5 and 6 As shown, the waterproof component 4 includes:

[0099] The first waterproof member 41 is located in the opening groove 11, covers the flexible conductive member 21, and presses the flexible conductive member 21 toward the supporting surface of the support platform 3;

[0100] The second waterproof member 42 covers the first waterproof member 41 and fills the gap between the opening groove 11, the first waterproof member 41 and the flexible conductive member 21;

[0101] The material of the second waterproof member 42 is different from that of the first waterproof member 41 .

[0102] Here, the waterproof component includes a first waterproof part and a second waterproof part. The first waterproof part is arranged in the open groove, covering the flexible conductive part and the bottom of the open groove, and performing preliminary waterproof treatment on the open groove area; and, while the first waterproof part fills the open groove area, it can squeeze the flexible conductive part toward the supporting surface of the support platform to further fix the flexible conductive part.

[0103] In actual implementation, due to the component preparation process and installation process, a tiny gap will be formed between the flexible conductive part, the first waterproof part and the opening groove of the middle frame. Therefore, a second waterproof part is also provided in the embodiment of the present disclosure. The second waterproof part covers the first waterproof part and fills the above-mentioned tiny gap, thereby sealing the opening groove and fully preventing water vapor from flowing out of the opening groove.

[0104] Here, the depth of the second waterproof member can be within a preset depth range to ensure the effectiveness of waterproofing. Here, the preset depth range is between 0.20 mm and 0.30 mm. Exemplarily, the depth of the second waterproof member can be 0.25 mm.

[0105] In the disclosed embodiment, the waterproof material of the first waterproof member is different from the waterproof material of the second waterproof member. For example, the material of the first waterproof member can be silicone, rubber, plastic, etc.; the material of the second waterproof member can be hot melt adhesive, UV curable adhesive, heat curing epoxy resin adhesive, etc.

[0106] Optionally, the waterproof performance of the material of the second waterproof component is better than the waterproof performance of the material of the first waterproof component, thereby improving the overall waterproof performance of the waterproof assembly.

[0107] The embodiment of the present disclosure can improve the overall waterproof performance of the waterproof assembly by providing the first waterproof component and the second waterproof component in the waterproof assembly, thereby ensuring the normal use of the button functions and the safe use of the internal components of the electronic device.

[0108] In some embodiments, the first waterproof member includes a first sealing portion and a second sealing portion;

[0109] a first sealing portion, covering the flexible conductive member and the supporting surface of the supporting platform, and filling a portion of the open groove;

[0110] The second sealing portion is arranged at the outer edge of the first sealing portion and surrounds the first sealing portion;

[0111] The hardness of the first sealing portion is greater than the hardness of the second sealing portion.

[0112] See also Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of the first waterproof member according to an exemplary embodiment. Figure 2 ; Figure 8 : is a schematic structural diagram of a first sealing portion and a second sealing portion according to an exemplary embodiment; Figure 7 and Figure 8 As shown, the first waterproof member 41 can be configured as a sealing plug, which is formed by a first sealing portion 411 and a second sealing portion 412 .

[0113] Here, combined Figures 5 to 8 As shown, the open groove 11 has a first groove wall 111, a second groove wall 112 and an open groove bottom 113, and of course also has other third groove walls not shown in the side section; wherein, the support platform 3 is arranged in the connection area between the first groove wall 111 and the open groove bottom 113, and the first waterproof component 41 is located in the open groove 11; the first sealing portion 411 of the first waterproof component 41 covers the supporting surface of the support platform 3 and fills the empty area in the open groove 11; the second sealing portion 412 of the first waterproof component 41 is fixedly connected to the second groove wall 112 and other third groove walls not shown in the side section.

[0114] In the embodiment of the present disclosure, the first sealing portion serves as the main body of the sealing plug and is made of a material with higher hardness. For example, the first sealing portion can be made of hard plastic, which can fully achieve partial sealing of the open groove area and extrude and fix the flexible conductive part; the second sealing portion surrounds the outer edge of the first sealing portion and is made of a material with lower hardness. For example, the second sealing portion can be made of soft plastic, which can fully achieve fixed connection with the groove wall of the open groove.

[0115] The embodiment of the present disclosure provides a first sealing portion and a second sealing portion to fully achieve a preliminary sealing and waterproofing effect on the opening groove area.

[0116] In some embodiments, the first sealing portion includes an avoidance opening, and the avoidance opening is provided on a side of the first sealing portion close to the support platform;

[0117] Wherein, the flexible conductive member passes through the avoidance opening and the slot of the opening slot in sequence.

[0118] like Figure 7 and Figure 8 As shown, the first sealing portion 411 is provided with an avoidance opening 43, and the avoidance opening 43 is arranged in the side area of ​​the first sealing portion 411 close to the support platform 3; wherein the width of the avoidance opening 43 is adapted to the width of the flexible conductive member 21, so that the flexible conductive member 21 fixedly arranged on the supporting surface of the support platform 3 can first pass through the avoidance opening 43 and then pass out from the notch of the opening groove.

[0119] It should be noted that the gap between the avoidance opening and the flexible conductive member can be filled and sealed by the second waterproof member proposed in the present disclosure, thereby ensuring the rigor and rationality of the waterproof treatment.

[0120] The embodiment of the present disclosure provides an avoidance opening in the first sealing portion, so that the flexible conductive part can pass through the first sealing portion smoothly, so that the electrical signal generated by the operation button can be transmitted to the processing module inside the electronic device, thereby ensuring the effectiveness of the button function.

[0121] In some embodiments, the second sealing portion is a flexible member, and the second sealing portion is interference fit with the groove wall of the open groove.

[0122] The second sealing portion is a flexible member, such as soft plastic, soft rubber or flexible foam.

[0123] Here, the second sealing portion surrounds the outer edge of the first sealing portion, but does not surround the above-mentioned avoidance opening; the second sealing portion contacts the groove wall of the opening groove (such as the second groove wall and the third groove wall mentioned above), and through the interference fit between the groove wall of the opening groove, achieves relative fixation with the opening groove and partial sealing of the opening groove.

[0124] In the embodiment of this disclosure, Figure 5 The second sealing portion 412 is perpendicular to the second groove wall 112 and the third groove wall (not shown in the figure) of the opening groove 11, and has an interference fit amount of a preset threshold in the direction perpendicular to the groove wall of the opening groove 11; wherein the above-mentioned preset threshold can be a value between 0.03mm and 0.07mm, and illustratively, the preset threshold can be 0.05mm.

[0125] In some embodiments, the second waterproof member is formed by dispensing glue.

[0126] In actual implementation, the first sealing part and the second sealing part form a sealing plug, which covers the flexible conductive part on the support platform. However, in the actual production process, due to the design of avoiding the opening and the installation process, a tiny gap will be formed between the flexible conductive part, the sealing plug and the opening groove of the middle frame.

[0127] The embodiment of the present disclosure drips glue into the notch of the open groove, so that the glue penetrates into the gap between the open groove, the first waterproof part and the flexible conductive part until the gap and the notch of the open groove are filled, and the glue forms glue dots, which form the above-mentioned second waterproof part.

[0128] here, Figure 5 and Figure 6 The second waterproof member 42 is shown to be formed by dispensing glue.

[0129] In the embodiment of the present disclosure, by setting glue dispensing, waterproof treatment can be further achieved for the opening groove, thereby improving the waterproof performance of the key area.

[0130] In some embodiments, the support platform has a support surface, which is opposite to the side of the middle frame and has an angle with the side of the middle frame;

[0131] The flexible conductive member is fixedly arranged on the supporting surface.

[0132] Here, see Figure 9 , Figure 9 It is a structural schematic diagram of a support platform according to an exemplary embodiment; here, the support platform 3 has a connecting surface 33 and a supporting surface 34. The support platform 3 has multiple connecting surfaces 33, which are respectively connected to the bottom of the open groove and multiple groove walls. The supporting surface 34 of the support platform 3 is opposite to the side of the middle frame and has an angle with the side of the middle frame. That is to say, the supporting surface 34 of the support platform 3 is an inclined surface, so when the flexible conductive part is overlapped on the supporting surface 34, the contact area is larger, which is conducive to the effective fixation of the flexible conductive part relative to the support platform 3.

[0133] in, Figure 9 The aforementioned positioning posts 31 are also shown.

[0134] It should be noted that the side of the first sealing part facing the support platform is also set as an inclined surface, and the inclined surface of the first sealing part has the same inclination angle as the above-mentioned support surface. In this way, after the flexible conductive part is overlapped and fixed on the support surface, the first sealing part and the support surface of the support platform cooperate to press the flexible conductive part to achieve the tightness of the structural installation.

[0135] The support surface of the support platform proposed in the embodiment of the present disclosure can be set as an inclined surface, which can increase the contact area between the flexible conductive member and the support surface, and is conducive to the effective fixation of the flexible conductive member relative to the support platform.

[0136] In some embodiments, see Figure 10 、 Figure 11 as well as Figure 12 , Figure 10 This is a schematic diagram of the structure of a key waterproof module according to an exemplary embodiment. Figure 3 ; Figure 11 This is a schematic diagram of the structure of a key waterproof module according to an exemplary embodiment. Figure 4 ; Figure 12 This is a schematic diagram of the structure of a key waterproof module according to an exemplary embodiment. Figure 5 ;like Figures 10 to 12 As shown, the support surface 34 is recessed toward the interior of the support platform 3 to form a limiting groove 35; the button waterproof module further includes: a reinforcement member 5;

[0137] The reinforcing member 5 is fixedly connected to the flexible conductive member 21 and embedded in the limiting groove 35 .

[0138] Here, the supporting surface is recessed toward the interior of the supporting platform to form a limiting groove, and the limiting groove can cooperate with the reinforcing member to limit the position, so that the flexible conductive member fixedly connected to the reinforcing member can be positioned and installed on the supporting platform.

[0139] The reinforcing member may be a metal member or a plastic member with high hardness, which is used to effectively support the flexible conductive member and reduce the problem of wrinkling of the flexible conductive member in the electronic device.

[0140] It should be noted that the reinforcement member may be welded to the flexible conductive member or may be bonded to the flexible conductive member, and the embodiments of the present disclosure do not limit this.

[0141] In the embodiment of the present disclosure, Figures 10 to 12 As shown, the retaining groove 35 may include a first retaining groove 351 and a second retaining groove 352. The first retaining groove 351 and the second retaining groove 352 have the same orientation, and the groove wall of the first retaining groove 351 is connected to the groove wall of the second retaining groove 352. The first retaining groove 351 is located at a position farther from the head of the key 2 than the second retaining groove 352, and the distance between the bottom of the first retaining groove 351 and the side of the middle frame is greater than the distance between the bottom of the second retaining groove 352 and the side of the middle frame. In other words, the first retaining groove 351 is formed by the support surface 34 being recessed inward relative to the second retaining groove 352.

[0142] Correspondingly, the reinforcement 5 also has a first reinforcement portion 51 and a second reinforcement portion 52. The first reinforcement portion 51 is embedded in the first limiting groove 351, and the second reinforcement portion 52 is embedded in the second limiting groove 352. This can further realize the positioning of the reinforcement and reduce the displacement of the reinforcement in the horizontal installation direction, thereby realizing the fixation of the flexible conductive member.

[0143] Among them, the reinforcement 5 can be set to a cloud shape, such as Figures 10 to 12 As shown, the two extended sections of the cloud-shaped reinforcement 5 are the first reinforcement portion 51 and the second reinforcement portion 52 mentioned above.

[0144] The embodiment of the present disclosure provides a limiting groove on the support platform, which can cooperate with the reinforcement of the flexible conductive member, thereby effectively achieving the positioning of the flexible conductive member.

[0145] In some embodiments, as Figures 9 to 12 As shown, the button waterproof module also includes:

[0146] The first adhesive member 6 is disposed in the limiting groove 35 and is used to adhere the reinforcing member 5 and the supporting surface 34 .

[0147] Here, the first adhesive member may be disposed on the side wall of the limiting groove, or on the bottom of the limiting groove, which is not limited in the embodiment of the present disclosure.

[0148] The first adhesive member may be double-sided adhesive foam or adhesive backing.

[0149] In the embodiment of the present disclosure, the first adhesive member is used to stick the above-mentioned reinforcement member and the side wall of the limiting groove to fix the reinforcement member on the support surface; or the first adhesive member is used to stick the above-mentioned reinforcement member and the bottom of the limiting groove to fix the reinforcement member on the support surface.

[0150] The embodiment of the present disclosure can achieve relative fixation between the reinforcing member and the supporting surface by setting a first adhesive member. Since the reinforcing member is fixedly connected to the flexible conductive member, the first adhesive member can achieve a fixed connection between the flexible conductive member and the supporting platform, thereby improving the installation stability of the flexible conductive member.

[0151] In some embodiments, the support platform is a trapezoidal body, and at least a portion of the inclined surface of the trapezoidal body constitutes the support surface.

[0152] like Figure 2 、 Figures 10 to 12 As shown, the support platform 3 can be set as a right-angled trapezoid, and at least part of the inclined surface of the right-angled trapezoid constitutes a support surface 34 for supporting the flexible conductive member 21; the vertical surface of the right-angled trapezoid constitutes a connecting surface 33 for connecting with the bottom and wall of the open groove 11.

[0153] In the embodiment of the present disclosure, the support platform is configured as a trapezoidal body, which can improve the flexibility and effectiveness of the structural design.

[0154] An embodiment of the present disclosure further provides an electronic device, the electronic device comprising:

[0155] The key waterproof module proposed in the above embodiments of the present disclosure;

[0156] The button is arranged on the side of the middle frame of the button waterproof module, and a flexible conductive member is provided at the end of the button;

[0157] The processing module is set on the middle frame and spaced apart from the buttons;

[0158] The flexible conductive element is passed through the notch of the opening slot of the key waterproof module and is electrically connected to the processing module.

[0159] Here, the processing module includes a central processing unit (CPU), which is used to execute program instructions within the electronic device, process data, and control the coordinated operation between other functional modules within the electronic device. The CPU chip is set on the main board, which is located on the main frame and is separated from the key area.

[0160] Among them, the flexible conductive part at the tail of the button passes through the opening slot of the button waterproof module, is electrically connected to the motherboard, and is electrically connected to the CPU chip through the signal wiring on the motherboard.

[0161] The electronic device proposed in the embodiment of the present disclosure has a key waterproof module, which can improve the phenomenon of water vapor entering the interior of the electronic device through the key area, thereby improving the stability and safety of the electronic device.

[0162] In some embodiments, the key includes multiple keys, the key waterproof modules include multiple keys, and one key waterproof module corresponds to one key.

[0163] Here, multiple buttons can be set on the same side of the middle frame, or distributed on different sides of the middle frame.

[0164] Exemplarily, the multiple buttons include a power button, a volume button, and a mute button; wherein, the power button is arranged on the first long side of the middle frame, and the volume button and the mute button are arranged at intervals on the second long side of the middle frame; at this time, the button waterproof modules proposed in the present disclosure can be set to three, and each of the three button waterproof modules corresponds to one button.

[0165] The electronic device proposed in the embodiment of the present disclosure is a thin and light mobile phone, and the above-mentioned button waterproof module is used to exemplarily illustrate the waterproof treatment of the thin and light mobile phone.

[0166] With the development of thin and light mobile phones, achieving high waterproofness for thin and light mobile phones has become an urgent need. This disclosure only uses the above-mentioned button waterproof module to achieve IPX8 waterproofness in the button area. Here, IPX8 waterproofness means that the mobile phone can withstand water at a depth of 1.5-30 meters underwater for 30 consecutive minutes under specific test conditions without affecting the performance of the mobile phone. The IPX8 waterproofness rating is the highest waterproofness standard currently and is suitable for various underwater activities such as swimming, diving, and snorkeling.

[0167] The key processing module proposed in the embodiment of the present disclosure can be combined with Figures 2 to 12 shown.

[0168] Here, in the key processing module, a support platform is set in the opening groove. The support platform serves as a bracket structure and can fix the FPC at the tail of the key. The material of the support platform is hard plastic to ensure the supporting function.

[0169] Among them, the bottom of the support platform has two positioning columns, and the bottom of the open groove is provided with two positioning holes, and the two positioning columns are limitedly matched with the two positioning openings; the bottom of the support platform avoids the positioning columns and is provided with a second adhesive part such as adhesive backing, and the adhesive backing sticks the support platform in the open groove.

[0170] In addition, the support platform has an inclined support surface, which can increase the matching area with the FPC. The support surface has a limiting groove to limit the FPC; the bottom of the limiting groove is provided with a first adhesive member such as adhesive for bonding the FPC.

[0171] It should be noted that for mobile phones with thin bodies, it is difficult to process complex inclined features on the middle frame. Therefore, the support platform proposed in the embodiment of the present disclosure can simplify the structure of the middle frame and reduce the difficulty of processing the middle frame.

[0172] Here, after the button is installed on the side of the middle frame, the FPC at the tail of the button can enter the open groove, so that the steel sheet fixedly connected to the FPC is limitedly matched with the above-mentioned limiting groove; here, the shape of the steel sheet matches the shape of the limiting groove, and the first adhesive part bonds the steel sheet to the bottom of the limiting groove, thereby realizing the positioning and preliminary fixation of the FPC.

[0173] Above the FPC, the disclosed embodiment provides a first waterproof component that conforms to the shape of the slot opening. The center of the first waterproof component is a first sealing portion made of hard plastic, and the perimeter is a second sealing portion made of soft plastic. The second sealing portion and the slot wall have an interference fit of 0.05mm in a direction perpendicular to the slot wall. Here, the first waterproof component presses the FPC against the support surface of the support platform and partially fills the slot opening, thereby further securing the FPC and preventing a large amount of water vapor from entering the interior of the device, achieving preliminary waterproofing of the key area.

[0174] Above the first waterproof part, the embodiment of the present disclosure also provides a second waterproof part, which is formed by dispensing glue and has a depth of 0.25mm; here, the dispensing glue penetrates into the tiny gap formed between the FPC, the sealing plug, and the middle frame to form the second waterproof part; the second waterproof part can further block water vapor from entering the interior of the fuselage, thereby achieving IPX8 level of waterproofness.

[0175] The button waterproof module proposed in the embodiment of the present disclosure has the characteristics of low cost and simple structure, and can be applied to thin and light mobile phones to effectively achieve IPX8 level waterproof treatment of the button area.
