[0041] In order to facilitate user interaction, a key is usually provided on the shell of an electronic device. In order to enable the key to be electrically connected to power electronic devices inside the electronic device, the shell is generally provided with an opening for the key installation and wiring. However, as such, the waterproof performance of the shell is poor, and water or other liquids can easily penetrate from the opening, causing the key to be short-circuited, corroded or damaged, seriously affecting the normal operation and service life of the electronic device.

[0042] Please refer to Figures 1 to 5 The electronic device 100 of the embodiment of the present application includes a shell 10, a mounting seat 20, a key assembly 30, a fixing cover 40 and a sealing member 50. The mounting seat 20 protrudes upward from the shell 10 and is formed with a first opening 21. The key assembly 30 includes a main body 31 and a key 32 provided on the main body 31, and the main body 31 is arranged in the first opening 21. The fixing cover 40 is provided with a second opening 41 on the top surface thereof. When the fixing cover 40 is mounted on the mounting seat 20, a fixing cavity for fixing the main body 31 is formed between the fixing cover 40 and the mounting seat 20, and the key 32 extends out of the second opening 41. The sealing member 50 is located between the fixing cover 40 and the shell 10, and is used to seal the fixing cavity.

[0043] The electronic device 100 provided in the application realizes the fixation of the key assembly 30 by the fixing cover 40 and the mounting seat 20, and realizes the sealing of the key assembly 30 by the sealing element 50 arranged between the fixing cover 40 and the shell 10, so as to avoid the water or other liquid from easily penetrating from the opening, causing the short circuit, corrosion or damage of the key 32, and to facilitate the normal operation of the electronic device 100 and prolong the service life of the electronic device 100.

[0044] Specifically, in the embodiment of the application, the shell 10 and the mounting seat 20 are integrally formed, and the mounting seat 20 is in the shape of a circular truncated cone with the top being wider than the bottom. The first opening 21 is arranged at the top of the mounting seat 20.

[0045] In the embodiment of the application, the key assembly 30 includes a cylindrical main body 31 and a cylindrical key 32 arranged at one end of the main body 31, and the diameter of the first opening 21 is larger than the diameter of the main body 31.

[0046] In the embodiment of the application, the fixing cover 40 is also integrally formed, and the fixing cover 40 is in the shape of a circular truncated cone with the top being wider than the bottom. The second opening 41 is arranged at the top of the fixing cover 40. Further, the diameter of the second opening 41 is slightly larger than the diameter of the key 32.

[0047] In the embodiment of the application, the sealing element 50 is a material or part for preventing the leakage of fluid or solid particles from the adjacent joint surface between the fixing cover 40 and the mounting seat 20 and preventing the intrusion of external impurities such as dust and water into the button assembly, and is usually arranged between the fixing cover 40 and the shell 10 or between the fixing cover 40 and the mounting seat 20.

[0048] In some embodiments, the shell 10 is further provided with a backlight 60, and the backlight 60 is arranged inside the shell 10 and partially inside the mounting seat 20. The backlight 60 is arranged in alignment with the key assembly 30 to serve as the backlight of the key assembly 30. Optionally, the backlight 60 can be an LED lamp bead.

[0049] Please refer to Figure 1 , Figure 2 and Figure 4 In some embodiments, the fixing cover 40 is threadedly connected with the mounting seat 20.

[0050] In this way, the threaded structure can provide good sealing performance to ensure that moisture and impurities cannot easily enter the inside of the key assembly 30.

[0051] Specifically, in the embodiments of the present application, the outer surface of the mounting seat 20 is provided with external threads, and the inner surface of the fixed cover 40 is provided with internal threads that cooperate with the external threads provided on the outer surface of the mounting seat 20. In this way, the threaded structure can provide good sealing performance, ensuring that moisture and impurities cannot easily enter the interior of the key assembly 30. Compared with some other waterproof methods, the threaded waterproof design is generally more durable and can withstand greater pressure and more severe environmental conditions. Although the threaded structure requires certain installation skills, once the correct installation method is mastered, the installation process is generally relatively simple and fast.

[0052] In the embodiments of the present application, the threads are triangular threads, both sides of the triangular threads are bevels, when the two threads are connected, a sealed pressure area can be generated between the bevels, thereby realizing the sealing effect. In addition, the triangular thread has excellent self-locking performance. When the triangular thread connects two parts, it can effectively prevent loosening, ensuring the stability and reliability of the connection. This feature makes the triangular thread perform well in occasions that need to withstand vibration or impact load. The triangular thread has a thicker root, which can withstand greater torque and tensile force, so it has higher strength and rigidity. This makes it have significant advantages in applications that bear heavy loads or require high durability. Because the shape of the triangular thread is relatively simple, its manufacturing and processing process is also relatively easy. This reduces production costs, improves production efficiency, and makes the triangular thread widely used in industrial production.

[0053] In other embodiments, the threads can also be selected as sawtooth threads, rectangular threads or trapezoidal threads. The specific thread shape can be selected and used according to actual needs, which will not be described here in detail.

[0054] Please refer to Figure 1 and Figure 3 In some embodiments, the key assembly 30 further includes a limiting plate 33, which is arranged around the annular body 31. The limiting plate 33 is arranged at one end of the body 31 close to the key 32, and the diameter of the limiting plate 33 is greater than the diameter of the first opening 21 and the second opening 41.

[0055] In this way, the limiting plate 33 is clamped by the fixed cover 40 and the mounting seat 20 to realize the fixation of the key assembly 30.

[0056] Specifically, in the embodiments of the present application, the limiting plate 33 is arranged at the connection between the body 31 and the key 32. In this way, when the key assembly 30 is installed, the body 31 is inserted into the first opening 21 at the top of the mounting seat 20, and the key 32 is extended from the second opening 41 of the fixed cover 40, so that the limiting plate 33 is clamped between the fixed cover 40 and the mounting seat 20, thereby realizing the fixation of the key assembly 30.

[0057] In other embodiments, the key assembly 30 can also be fixed by other methods, for example, the main body is threadedly connected with the mounting seat, the case is threadedly connected with the fixing cover, etc. The specific fixing method can be selected according to actual needs, and will not be described here.

[0058] Referring to Figure 1 and Figure 2 In some embodiments, the inner top surface of the fixing cover 40 is provided with a fixing groove 42 for fixing the limiting plate 33.

[0059] In this way, the displacement of the key assembly 30 can be limited, and movement of the key 32 in the second opening 41 can be avoided.

[0060] Specifically, in the embodiments of the present application, the inner top surface of the fixing cover 40 is provided with a fixing groove 42 around the second opening 41 for fixing the limiting plate 33, the fixing groove 42 is circular, and the diameter of the fixing groove 42 is greater than or equal to the diameter of the limiting plate 33.

[0061] Further, the side surface of the fixing groove 42 is provided in a slope, so that the side surface of the fixing groove 42 can play a guiding role, so that the limiting plate 33 can be accurately fixed in the fixing groove 42, and displacement of the key assembly 30 when the fixing cover 40 is installed can be avoided.

[0062] In some embodiments, the limiting plate 33 can also be selected to be provided in other shapes, and correspondingly, the fixing groove 42 can also be provided in other shapes according to the shape of the limiting plate 33, so as to meet different use conditions, for example, the limiting plate 33 is provided in a non-circular shape, and the fixing groove 42 is provided in a shape corresponding to the limiting plate 33, so as to further fix the key assembly 30, and avoid rotation of the key assembly 30 during use.

[0063] Referring to Figure 1 In some embodiments, the sealing member 50 includes a first sealing member 51 and a second sealing member 52, the first sealing member 51 is arranged at the first opening 21, and the second sealing member 52 is arranged on the housing 10 at the bottom of the mounting seat 20.

[0064] In this way, two sealing members 50 are arranged at the same time, which is beneficial to further improve the sealing effect of the key assembly 30.

[0065] Specifically, in the embodiments of the present application, the two sealing members 50 are integrally formed in an integral structure, and the material of the sealing member 50 is silica gel. In other embodiments, the material of the sealing member 50 can also be rubber, latex, plastic or other materials, and the specific material can be selected according to actual needs, and will not be described here.

[0066] Further, the first sealing member 51 is arranged between the fixing cover 40 and the mounting seat 20, and the second sealing member 52 is arranged between the fixing cover 40 and the shell 10. In this way, by screwing the fixing cover 40, the pressing of the waterproof gasket on the top and bottom of the mounting seat 20 is realized, and the waterproof function is realized.

[0067] In some embodiments, only the first sealing member 51 or the second sealing member 52 can be arranged, so that the sealing of the fixing cavity can also be realized, but the sealing effect is poor.

[0068] Please refer to Figure 1 , Figure 2 and Figure 1 In some embodiments, the first sealing member 51 includes a sealing portion 511 and a first fixing portion 512, the sealing portion 511 is annular, and the first fixing portion 512 is arranged around the sealing portion 511. The top of the mounting seat 20 is provided with a limiting portion 22, and the first fixing portion 512 is configured to be sleeved outside the limiting portion 22 when the first sealing member 51 is mounted on the mounting seat 20.

[0069] In this way, the first sealing member 51 can be fixed on the limiting portion 22, so as to avoid the movement of the first sealing member 51 affecting the waterproof performance when the fixing cover 40 is installed.

[0070] Specifically, in the embodiments of the present application, the first fixing portion 512 is arranged around the sealing portion 511 and forms an included angle with the sealing portion 511, the included angle is obtuse, the thickness of the first fixing portion 512 is substantially the same as that of the sealing portion 511, a small transition round corner is arranged at the connection between the first fixing portion 512 and the sealing portion 511, so as to facilitate the demolding of the first sealing member 51, and further, the outer surface of the first fixing portion 512 is parallel to the outer surface of the mounting seat 20.

[0071] In the embodiments of the present application, the outer side of the top surface of the mounting seat 20 is provided with an annular limiting portion 22 around the first opening 21, the inner diameter of the limiting portion 22 is equal to the inner diameter of the first opening 21, and the outer diameter of the limiting portion 22 is smaller than the diameter of the top surface of the mounting seat 20. Further, the outer diameter of the limiting portion 22 is substantially equal to the inner diameter of the first fixing portion 512, so that the first fixing portion 512 can be stably fixed on the limiting portion 22.

[0072] Please refer to Figure 1 and Figure 2 In some embodiments, when the first sealing member 51 is mounted on the mounting seat 20, the outer surface of the first fixing portion 512 is flush with the outer surface of the mounting seat 20.

[0073] In this way, the first sealing member 51 can be avoided to be too large, which leads to the difficulty of installing the fixing cover 40 or even causes the mounting rod to be unable to be installed.

[0074] Specifically, in the embodiment of the present application, the outer surface of the first fixing portion 512 is in the shape of a truncated cone, and the outer diameter of the bottom of the first fixing portion 512 is substantially equal to the diameter of the top surface of the mounting seat 20.

[0075] In some embodiments, the outer surface of the first fixing portion 512 can also extend outward and slightly beyond the outer surface of the mounting seat 20. In this way, when the fixing cover 40 is connected to the mounting seat 20, the first fixing portion 512 slightly beyond the outer surface of the mounting seat 20 is beneficial to improve the sealing effect between the fixing cover 40 and the mounting seat 20.

[0076] Please refer to Figure 5 , Figure 1 and Figure 5 In some embodiments, the inner surface of the first fixing portion 512 is provided with a limiting boss 5121, and the outer wall surface of the limiting portion 22 is provided with an avoiding groove 23 matched with the limiting boss 5121.

[0077] In this way, through the cooperation of the limiting boss 5121 and the avoiding groove 23, the fixation of the first fixing portion 512 can be further realized.

[0078] Specifically, in the embodiment of the present application, the limiting boss 5121 is arranged near the bottom wall edge of the inner side surface of the first fixing portion 512, and the limiting boss 5121 is annularly arranged along the first fixing portion 512. Correspondingly, the avoiding groove 23 is arranged at the root of the limiting portion 22 connected with the mounting seat 20, and the avoiding groove 23 is annularly arranged along the outer surface of the limiting portion 22.

[0079] In some embodiments, the limiting boss 5121 can also be arranged at intervals along the bottom wall edge of the inner side surface of the first fixing portion 512. At this time, the avoiding groove 23 is annularly arranged along the outer surface of the limiting portion 22, or can be arranged according to the arrangement of the limiting boss 5121.

[0080] In other embodiments, the limiting boss 5121 can also be arranged in other shapes, and at the same time, the avoiding groove 23 is arranged in a shape matched with the shape of the limiting boss 5121. The specific shapes of the limiting boss 5121 and the avoiding groove 23 can be selected according to actual needs, and will not be described here in detail.

[0081] Please refer to Figure 1 and Figure 2 In some embodiments, the first sealing member 51 includes a second fixing portion 513, the second fixing portion 513 is in the shape of a tube, the second fixing portion 513 is arranged inside the sealing portion 511, and the second fixing portion 513 is configured to extend into the first opening 21 when the first sealing member 51 is installed on the mounting seat 20, and the main body 31 is arranged inside the second fixing portion 513.

[0082] In this way, the second fixing portion 513 can be combined with the auxiliary fixing button assembly 30, and the second fixing portion 513 is arranged between the first opening 21 and the main body 31 of the button assembly 30, which is beneficial to seal the first opening 21 and improve the waterproof performance of the electronic device 100.

[0083] Specifically, in the embodiment of the present application, the inner diameter of the second fixing portion 513 is substantially equal to the outer diameter of the main body 31 of the button assembly 30, the outer diameter of the second fixing portion 513 is substantially equal to the diameter of the first opening 21, and the length of the second fixing portion 513 is greater than or equal to the length of the main body 31 of the button assembly 30. Further, the first fixing portion 512, the sealing portion 511, and the second fixing portion 513 are integrally formed in an integrated structure. It should be noted that the thickness of the second fixing portion 513 is approximately equal to the thickness of the sealing portion 511, and a transition fillet is arranged at the connection between the second fixing portion 513 and the sealing portion 511. In this way, the injection molding defects during processing can be avoided, and the first sealing member 51 can be easily demolded.

[0084] Please refer to Figure 5 and Figure 1 Figure 5 Figure 1 Figure 2 In some embodiments, the housing 10 is provided with a containing groove 11 for accommodating the second sealing member 52, and the containing groove 11 is arranged around the mounting seat 20.

[0085] In this way, the containing groove 11 is used to fix and limit the position of the second sealing member 52, so as to avoid displacement of the second sealing member 52 due to friction when the fixing cover 40 is installed, thereby affecting the sealing effect.

[0086] Specifically, in the embodiment of the present application, the second sealing member 52 is in the shape of a ring, and the inner diameter of the second sealing member 52 is substantially equal to the outer diameter of the root of the mounting seat 20. In this way, the inner surface of the second sealing member 52 can be closely arranged on the root of the mounting seat 20, which is beneficial to improve the sealing effect.

[0087] In the embodiment of the present application, the outer diameter of the second sealing member 52 is greater than or equal to the outer diameter of the opening of the fixing cover 40. In this way, it can be ensured that the edge of the fixing cover 40 can be completely pressed on the top surface of the second sealing member 52, and when the fixing cover 40 is installed and tightened, the edge of the fixing cover 40 can press and compress the second sealing member 52 to form a seal, which is beneficial to improve the sealing effect.

[0088] The containing groove 11 is arranged around the mounting seat 20, which ensures that the second sealing member 52 can be closely fitted after installation, not only plays a role in stable fixation, but also effectively improves the overall sealing performance. Through such design, not only the connection strength between the housing 10 and the mounting seat 20 is enhanced, but also the stability and reliability of the related components during operation are further ensured.

[0089] Further, the depth of the accommodating groove 11 is less than the thickness of the second sealing member 52, so that part of the second sealing member 52 is exposed from the accommodating groove 11, and the edge of the fixing cover 40 provides a larger compression space for the second sealing member 52 when the edge of the fixing cover 40 presses and compresses the second sealing member 52, thereby further improving the sealing effect of the second sealing member 52.

[0090] In some embodiments, the second sealing member 52 can also be replaced by a sealing glue, which is arranged in the accommodating groove 11, and the sealing glue connects the fixing cover 40 and the shell 10 by adhesion when the fixing cover 40 is installed and tightened, so as to achieve the sealing effect. It should be noted that, in this way, the original sealing glue needs to be cleaned every time the fixing cover 40 is disassembled, and the sealing glue needs to be refilled when the fixing cover 40 is installed, so as to avoid the sealing effect being poor due to the failure of the sealing glue.

[0091] In the description of the present specification, the description of the terms "some embodiments", "one embodiment", "some embodiments", "illustrative embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiments or examples are included in at least one embodiment or example of the present application.
