Furthermore, the metal cover is usually located on the outside of the watch, away from interference from internal electronic components such as the screen, allowing the antenna to interact more directly with external signal sources, reducing interference from internal circuits and other components, thus improving signal quality. In addition, traditional under-screen antennas are limited by the screen and other internal structures, resulting in a relatively fixed layout.

[0073] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Unless otherwise stated, "a plurality of" means two or more.

[0078] As mentioned in the background section, the antenna technology of existing smart wearable devices has many problems in practical applications. For example, traditional under-display antennas are limited by the screen and other internal structures, and their layout is relatively fixed. This fixed layout cannot be flexibly adjusted according to different usage scenarios and signal requirements, which limits the optimization of the signal transmission performance of smart wearable devices. While slot antennas can improve signal reception to a certain extent, they require obvious gaps in the shell, which not only damages the appearance integrity of the device, but also requires precise control of the size, shape and position of the gaps, making the antenna design quite difficult.

[0079] To address the aforementioned issues, this application provides a smart wearable device that integrates a metal top cover with an antenna, enabling the antenna to interact more directly with external signal sources. This reduces interference from internal circuits and other components, thereby improving signal quality and reducing the complexity of antenna design and manufacturing. It also makes it easier to find the optimal antenna position for the best signal transmission effect, thus optimizing the signal transmission performance of the smart wearable device.

[0080] The technical solution of the smart wearable device of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0081] See Figure 1 and Figure 2 This embodiment provides a smart wearable device 1, which includes: a mid-frame support 100, a motherboard 200, and a metal top cover 300. The mid-frame support 100 has an internal space; the motherboard 200 is disposed in the internal space of the mid-frame support 100; the metal top cover 300 is stacked on top of the mid-frame support 100 and has an antenna feed point, which is electrically connected to the motherboard 200.

[0082] The metal cover 300 of the smart wearable device 1 typically provides robust physical protection for the internal components of the smart wearable device 1. The metal cover 300 can work with other sealing components to form a tight protective layer, preventing moisture, dust and other impurities from entering the interior of the smart wearable device 1. In addition, the metal cover 300 has a high texture and gloss, which can add a sense of fashion and high-end to the appearance of the smart watch. For example, a stainless steel cover can show a tough and sturdy appearance, while an aluminum alloy cover is lighter and more fashionable.

[0083] In this embodiment, by setting an antenna feed point on the metal cover 300, the metal cover 300 can be combined with the antenna. The metal cover 300 usually has a large surface area, which can provide a wider signal receiving and transmitting area, better capture and transmit signals, and reduce the possibility of signal blockage or attenuation. Furthermore, the position of the metal cover 300 is usually on the outside of the watch, away from interference from internal electronic components such as the screen, which allows the antenna to interact more directly with external signal sources, reducing interference from internal circuits and other components, thereby improving the quality of signal transmission.

[0084] Furthermore, traditional under-display antennas are limited by the screen and other internal structures, resulting in a relatively fixed layout. Slot antennas, on the other hand, require a noticeable slot in the casing, and the size, shape, and position of the slot are difficult to adjust flexibly. In this embodiment, by integrating the antenna with the metal cover 300, the antenna layout can be optimized according to the overall design of the watch and its signal requirements. For example, the best signal reception effect can be achieved by adjusting the shape, size, and material distribution of the metal cover 300. Integrating the antenna with the metal cover 300 not only maintains the integrity of the watch's metal appearance, making it more aesthetically pleasing and fashionable, but also allows for the use of mature metal processing technology and antenna design technology to process the metal cover 300, reducing the complexity of antenna design and manufacturing. This allows for more flexible adjustments based on the overall design and signal requirements of the smart wearable device 1, making it easier to find the optimal antenna position for the best signal transmission effect, thereby optimizing the signal transmission performance of the smart wearable device 1.

[0085] In one possible embodiment, see Figure 2 and Figure 4 The smart wearable device 1 also includes a display screen 400, which is disposed on the upper surface of the mid-frame support 100; the metal top cover 300 is a frame-shaped component, which is disposed around the outer periphery of the display screen 400.

[0086] The metal cover 300 mentioned above is a frame-shaped component. It should be understood that the metal cover 300 is a closed geometric shape that surrounds the outer perimeter of the display screen 400. It can be rectangular, circular, elliptical or other specific shapes. The specific shape depends on the design requirements and overall style of the smart wearable device 1 and is not limited here.

[0087] By surrounding the display screen 400 with a metal cover 300, a physical barrier can be formed to prevent the display screen 400 from being subjected to external impacts, scratches, and pressure during daily use. Furthermore, when the metal cover 300 is placed around the display screen 400, the spatial layout of the smart wearable device 1 can be better utilized to optimize the performance of the antenna. For example, by rationally designing the shape and size of the metal cover 300, the radiation direction and frequency response of the antenna can be adjusted to improve the signal strength and stability.

[0088] In one possible embodiment, see Figure 3 The metal cover 300 includes a plurality of spaced metal segments 310, which are connected to each other by an insulating member 320, and at least one metal segment 310 is provided with an antenna feed point.

[0089] By dividing the metal cover 300 into multiple spaced metal segments 310 and connecting them with an insulating component 320, signal interference between the metal segments 310 can be effectively reduced. Furthermore, when multiple metal segments 310 are equipped with antenna feed points, multi-band antenna design can be satisfied, better adapting to the signal requirements of different frequency bands. Different metal segments 310 can be optimized for specific frequency bands, improving signal selectivity and sensitivity.

[0090] In one possible embodiment, see Figure 5 The motherboard 200 includes a communication module, a Bluetooth module, a WIFI module, and / or an NFC module; multiple metal segments 310 include a first metal segment 3101 and a second metal segment 3102. The first metal segment 3101 is provided with a first antenna feed point 3301, which is electrically connected to the communication module on the motherboard 200. The second metal segment 3102 is provided with a second antenna feed point 3302, which is electrically connected to the Bluetooth module, WIFI module, and / or NFC module on the motherboard 200.

[0091] In daily life, users can use the communication module of smart wearable device 1 to make voice calls, send and receive text messages, etc. The Bluetooth module can connect to the user's mobile phone or other Bluetooth devices to realize functions such as notification reminders and music playback control. The WIFI module enables smart wearable device 1 to connect to wireless networks to realize functions such as data synchronization and software updates. The NFC module can be used for near-field communication, such as mobile payment and access card simulation. Smart wearable device 1 is usually equipped with various sensors, such as heart rate sensors and accelerometers. During exercise, these sensors can monitor the user's exercise status and health data in real time, and upload the data to the cloud for analysis and storage through the communication module or WIFI module.

[0092] In this embodiment, the first antenna feed point 3301 on the first metal segment 3101 is electrically connected to the communication module, and the second antenna feed point 3302 on the second metal segment 3102 is electrically connected to the Bluetooth module, the WIFI module, and / or the NFC module. This allows for antenna optimization to meet the needs of different modules and improve signal reception and transmission strength. For example, the communication module typically requires a strong signal coverage range, while the Bluetooth and WIFI modules prioritize signal stability and transmission speed. By setting the first antenna feed point 3301 on the first metal segment 3101 and the second antenna feed point 3302 on the second metal segment 3102, the signal requirements of different modules can be better met. Furthermore, within the limited space of the smart wearable device 1, multiple modules are integrated on the motherboard 200, and the antenna function is achieved through multiple metal segments 310 of the metal cover 300. This fully utilizes the internal space of the smart wearable device 1, making it thinner and more compact.

[0093] In one possible embodiment, see Figure 5 The multiple metal segments 310 also include a third metal segment 3103 and a fourth metal segment 3104. The third metal segment 3103 is provided with a third antenna feed point 3303, and the fourth metal segment 3104 is provided with a fourth antenna feed point 3304. The first metal segment 3101 and the second metal segment 3102 are arranged opposite to each other, and the third metal segment 3103 and the fourth metal segment 3104 are arranged opposite to each other.

[0094] By setting different antenna feed points on different metal segments 310, independent transmission of signals in different frequency bands can be achieved. For example, the antenna feed point on the first metal segment 3101 can be dedicated to receiving low-frequency signals, such as communication signals; the antenna feed point on the second metal segment 3102 can be used for mid-frequency signals, such as Bluetooth signals; and the antenna feed points on the third metal segment 3103 and the fourth metal segment 3104 correspond to different high-frequency signals, such as Wi-Fi and NFC signals. This avoids mutual interference between signals in different frequency bands, improves signal quality and stability, and addresses the different performance requirements of antennas for different frequency bands. By using frequency band design, optimization can be performed for the characteristics of each frequency band. For example, low-frequency signals require larger antenna size and lower antenna efficiency, while high-frequency signals require smaller antenna size and higher antenna efficiency. By setting the antenna feed points of different frequency bands on different metal segments 310, independent antenna designs can be carried out according to the requirements of the frequency band, thereby improving the performance and efficiency of the antenna. For some specific frequency bands, such as 5G communication bands, which require higher bandwidth and faster data transmission speeds, more antenna resources can be allocated to these frequency bands, and the antenna layout and parameters can be optimized to meet the needs of high-speed data transmission.

[0095] For example, in this embodiment, the first antenna feed point 3301 includes a positive feed point and a negative feed point (together forming a loop with the communication module), the second antenna feed point 3302 includes a positive feed point and a negative feed point (together forming a loop with the Bluetooth module) and a WIFI feed point. Simultaneously, a WIFI feed point (i.e., the third antenna feed point 3303 or the fourth antenna feed point 3304) is also provided on the third metal segment 3103 or the fourth metal segment 3104, thereby collectively forming a loop with the WIFI module. Thus, when some frequency bands cannot be fully implemented on the first metal segment 3101 and the second metal segment 3102, the third metal segment 3103 and the fourth metal segment 3104 can be used to design some frequency bands, thereby expanding the signal coverage and adaptability of the smart wearable device 1. Alternatively, if the third metal segment 3103 and the fourth metal segment 3104 are not needed, the third metal segment 3103 and the fourth metal segment 3104 can be grounded to avoid signal interference to the first metal segment 3101 and the second metal segment 3102.

[0096] In one possible embodiment, the insulating component 320 is made of plastic, and the multiple metal segments 310 are made of stainless steel. The insulating component 320 and the multiple metal segments 310 are integrally formed by a nano-injection molding process using stainless steel.

[0097] Among them, the stainless steel nano-injection molding process treats the surface of multiple metal segments 310 with a specific solution to form a nanoscale microporous structure, which increases the contact area between the metal segments 310 and the plastic. The treated metal segments 310 are then placed into an injection mold, the plastic is heated to a molten state, and then the plastic is injected into the mold through an injection molding machine to fill the micropores on the stainless steel surface, forming an insulating part 320 that is tightly bonded to the metal.

[0098] The nano-injection molding process enables the stainless steel metal segment 310 to be tightly bonded to the plastic insulating component 320, avoiding separation or loosening of the metal segment 310 and the insulating component 320 during use, thus ensuring the structural reliability of the metal cover 300.

[0099] In one possible embodiment, see Figure 6 The middle frame support 100 has a first lug 500 and a second lug 600 on opposite sides; a first metal segment 3101 is located near the first lug 500, and a second metal segment 3102 is located near the second lug 600.

[0100] For a smart wearable device 1 with wireless communication function, the position of the first metal segment 3101 and the second metal segment 3102 will affect the reception and transmission of signals. In this embodiment, the first metal segment 3101 and the second metal segment 3102 are respectively positioned close to the first lug 500 and the second lug 600, so that when the smart wearable device 1 is worn on the human body, the first metal segment 3101 and the second metal segment 3102 are relatively far away from the human body, reducing the shielding effect of the human body on the signal.

[0101] In one possible embodiment, the first lug 500 is the lug furthest from the human body, and the second lug 600 is the lug closest to the human body.

[0102] The first lug 500 is the lug furthest from the human body, and the second lug 600 is the lug closest to the human body. This should be understood as follows: when the smart wearable device 1 (such as a smartwatch) is worn on the human body, the first lug 500 is located at the end furthest from the human body. When the watch is worn on the wrist, it is usually the lug on the outside or above the wrist. The second lug 600 is closer to the human body, usually the lug on the inside or below the wrist.

[0103] The first metal segment 3101, where the first antenna feed point 3301 connected to the communication module is located, is positioned closer to the first lug 500 at the end furthest from the human body. This minimizes interference from the human body with the communication signal, resulting in a more stable and clearer signal quality during voice calls, data transmission, and other communication functions. Similarly, the second metal segment 3102, where the second antenna feed point 3302 connected to the Bluetooth, Wi-Fi, and / or NFC modules is located, is positioned closer to the human body at the second lug 600. Since these modules are typically close to the human body during use, placing them closer to the human body better adapts to the surrounding environment. The surrounding electromagnetic environment reduces interference caused by the absorption and reflection of signals by the human body. Furthermore, different antenna feed points and modules are positioned close to different tabs according to their usage scenarios and signal characteristics. This allows for better utilization of the tabs' positional advantages and spatial layout, optimizing the antenna's radiation direction and reception angle. For example, communication modules require a wider signal coverage range, so placing them closer to the tab furthest from the human body allows the signal to radiate into a wider space. Meanwhile, Bluetooth, Wi-Fi, and NFC modules typically communicate with other devices over shorter distances, and positioning them closer to the human body allows for better signal interaction with nearby devices.

[0104] In one possible embodiment, see Figure 6 The middle frame support 100 is provided with an earphone compartment 110; along the thickness direction of the middle frame support 100, the first metal segment 3101 and the second metal segment 3102 avoid the location of the charging position in the earphone compartment 110.

[0105] The aforementioned middle frame support 100 is in the direction indicated by arrow Y in the figure.

[0106] The charging position in the earphone compartment 110 generates a certain magnetic field during charging. If the first metal segment 3101 and the second metal segment 3102 do not avoid the charging position, these magnetic fields may interfere with the antenna signal. In this embodiment, by avoiding the location of the charging position, the first metal segment 3101 and the second metal segment 3102 can effectively reduce the impact of the charging magnetic field on the antenna signal and ensure that the antenna can stably receive and transmit signals.

[0107] In one possible embodiment, see Figure 6 The smart wearable device 1 includes a bottom shell 700, which is stacked below the mid-frame support 100; a first metal segment 3101 has a first extension 3101a, which extends toward the first lug 500, and the first extension 3101a, the side wall of the mid-frame support 100, the first lug 500 and the bottom shell 700 frame together form a first receiving space 1101; a second metal segment 3102 has a second extension 3102a, which extends toward the second lug 600, and the second extension 3102a, the side wall of the mid-frame support 100, the second lug 600 and the bottom shell 700 frame together form a second receiving space 1102; the first receiving space 1101 and the second receiving space 1102 are connected to form an earphone compartment 110.

[0108] In smart wearable device 1, space is usually limited. In this embodiment, the first extension 3101a, the side wall of the middle frame bracket 100, the first lug 500, and the bottom shell 700 frame are enclosed to form a first accommodating space 1101, and the second extension 3102a, the side wall of the middle frame bracket 100, the second lug 600, and the bottom shell 700 frame are enclosed to form a second accommodating space 1102. The first accommodating space 1101 and the second accommodating space 1102 are connected to form an earphone compartment 110. This makes full use of the internal space of the device and can provide a suitable storage space for the earphone without significantly increasing the overall size of the smart wearable device 1. It can also integrate the earphone with the smart wearable device 1, making it convenient for users to carry and use. Users do not need to carry an additional earphone case. They only need to wear the smart wearable device 1 to use the earphone at any time. This integrated design improves user convenience and reduces the burden of carrying items.

[0109] In one possible embodiment, see Figures 7 to 11The antenna feed point is provided with a first conductive contact 340; the mid-frame bracket 100 has a first abutment surface 120, which is located outside the internal space and is separated from the internal space by the side wall of the mid-frame bracket 100. A first antenna wire is provided on the first abutment surface 120; a metal cover 300 is installed on the first abutment surface 120, and the first conductive contact 340 abuts against the first antenna wire; a through hole 140 is provided on the side wall of the mid-frame bracket 100, and the first antenna wire is electrically connected to the main board 200 through the through hole 140.

[0110] The first antenna conductor (not shown in the figure) is placed on a specific first contact surface 120 and connected to the main board 200 through a through hole 140 in the side wall of the middle frame bracket 100. This makes the routing of the first antenna line clear and avoids spatial chaos and the risk of interference to other components caused by the first antenna conductor randomly moving inside the middle frame. Furthermore, the first antenna conductor is placed on the first contact surface 120 of the middle frame bracket 100, and the metal cover 300 is installed on this surface to make the conductive contact abut against the antenna conductor. This structure is very convenient during the production and assembly process. Workers can first install the antenna conductor on the first contact surface 120 and then install the metal cover 300 to ensure accurate contact between the conductive contact and the antenna conductor, reducing the installation difficulty and the probability of error, and improving production efficiency. In addition, when the antenna needs to be repaired or replaced, only the metal cover 300 needs to be removed to directly access the first antenna conductor and the conductive contact, which is convenient for testing and operation. It does not require large-scale disassembly of other components inside the middle frame bracket 100, reducing maintenance costs and time costs.

[0111] In one possible embodiment, see Figures 10 to 13 The motherboard 200 is provided with a second conductive contact 210; the mid-frame bracket 100 has a second abutment surface 130, which is located in the internal space and is disposed opposite to the first abutment surface 120 along the thickness direction of the mid-frame bracket 100. A second antenna conductor is provided on the second abutment surface 130, one end of which is electrically connected to the via 140 and the other end abuts against the second conductive contact 210.

[0112] By setting a second conductive contact 210 on the motherboard 200 and a second antenna conductor (not shown in the figure) on the second abutment surface 130 inside the middle frame bracket 100, and with one end of the second antenna conductor electrically connected to the via 140 and the other end abutting against the second conductive contact 210, a continuous signal transmission path is formed, reducing signal deflection and interference during transmission, and improving signal transmission efficiency and stability. Furthermore, by setting the second abutment surface 130 inside the middle frame bracket 100 and opposite to the first abutment surface 120 along the thickness direction, the internal space of the middle frame bracket 100 is fully utilized. This allows for more layout space for the antenna system without increasing the overall size of the smart wearable device 1, making the internal structure of the middle frame bracket 100 more compact and facilitating the miniaturization of the smart wearable device 1.

[0113] The first antenna wire and the second antenna wire can be integrally formed and pass through the via 140, or they can be set in segments and connected through the via 140.

[0114] In one possible embodiment, both the first conductive contact 340 and the second conductive contact 210 are conductive springs.

[0115] Since both the first conductive contact 340 and the second conductive contact 210 are conductive springs, and conductive springs are elastic, they can form a stable pressure contact with the corresponding antenna wire or motherboard 200 contact area after installation. This elastic contact can ensure that even when affected by factors such as vibration and temperature changes during the use of the device, a good conductive connection can always be maintained, thereby ensuring the stability of signal transmission. For example, during the wearing of the smart wearable device 1, the movement of the human body may cause the device to be vibrated to varying degrees. The elasticity of the conductive spring can effectively buffer these vibrations and prevent signal interruption or attenuation caused by poor contact. In addition, the installation of conductive springs is relatively simple. They can usually be fixed in the corresponding position by snap-fitting, welding, etc. Workers can quickly install the conductive springs in place, improving production efficiency.

[0116] In one possible embodiment, see Figure 7 A waterproof component 350 is provided on the side surface of the metal top cover 300 facing the middle frame bracket 100, and the waterproof component 350 is attached around the outer periphery of the first conductive contact 340.

[0117] The waterproof component 350 is attached around the outer periphery of the first conductive contact 340, forming an effective waterproof barrier at the connection between the metal top cover 300 and the mid-frame bracket 100. When the smart wearable device 1 comes into contact with water or is in a humid environment, the waterproof component 350 can prevent moisture from entering the smart wearable device 1 through the connection, protecting the internal antenna system, motherboard 200 and other sensitive electronic components.

[0118] In one possible embodiment, the waterproof component 350 is foam adhesive.

[0119] Because foam adhesive has a soft texture and a certain degree of elasticity, it can adhere tightly to the connection between the metal top cover 300 and the middle frame support 100, as well as around the outer periphery of the first conductive contact 340, thereby forming a good sealing effect and effectively preventing moisture intrusion. Furthermore, the surfaces of the metal top cover 300 and the middle frame support 100 may not be completely flat, and foam adhesive can adapt well to these irregular surface shapes. It can fill tiny gaps and uneven areas, ensuring consistent waterproof performance. In addition, foam adhesive has a certain cushioning property, which can absorb and disperse the impact and vibration experienced by the smart wearable device 1 during use. When the smart wearable device 1 is subjected to collisions, drops, or other external forces, foam adhesive can reduce the impact on internal electronic components and reduce the risk of damage.

[0120] Of course, waterproof component 350 is not limited to foam adhesive. For example, waterproof component 350 can also be hot melt adhesive, EPDM rubber sealing strip, silicone sealing strip, and other materials with waterproof function.

[0121] In one possible implementation, the surface of the metal top cover 300 facing the middle frame bracket 100 is provided with a first mounting groove 360 ​​for mounting the first conductive contact 340 and / or a second mounting groove 370 for mounting the waterproof component 350. The first mounting groove 360 ​​provides a dedicated mounting position for the conductive contact, allowing it to be stably fixed between the metal top cover 300 and the middle frame bracket 100. This ensures that the conductive contact will not be displaced due to vibration, collision, or other external forces during the use of the device, thereby guaranteeing the stability and reliability of the conductive contact. The second mounting groove 370 provides a suitable mounting position for the waterproof component 350, allowing the waterproof component 350 to better integrate with the metal top cover 300 and the middle frame bracket 100, forming an effective waterproof seal. This optimizes the waterproof structure of the device, improves its waterproof performance, and protects the electronic components inside the smart wearable device 1 from moisture corrosion.

[0122] In one possible embodiment, see Figure 8 The middle frame bracket 100 is provided with a detection hole 150. One end of the detection hole 150 is connected to the interior of the middle frame bracket 100, and the other end is connected to the space formed by the surrounding foam adhesive.

[0123] The presence of the detection hole 150 provides a direct way to test the waterproof performance of the smart wearable device 1. During the production process, a certain pressure of gas or liquid can be injected into the space surrounded by foam adhesive through the detection hole 150 from the internal space of the middle frame bracket 100 to test whether the waterproof sealing performance of the device meets the design requirements.

[0124] In one possible embodiment, both the first antenna conductor and the second antenna conductor are metal layer traces.

[0125] Among them, metal layer traces refer to the process of forming trace patterns directly on the mid-frame bracket 100 through printed circuit board (PCB) technology, chemical vapor deposition (CVD) or laser processing technology.

[0126] Metal layer routing can precisely control parameters such as the width, spacing, and thickness of the first antenna conductor and the second antenna conductor, ensuring the consistency and repeatability of the routing. It can also be flexibly laid out and routed according to the circuit design requirements, and can achieve precise routing within the limited space on the mid-frame bracket 100.

[0127] In one possible embodiment, the metal layer traces are formed by laser engraving.

[0128] Laser engraving technology can achieve very high precision, accurately etching patterns of metal layer traces within a tiny size range. This ensures the accuracy and stability of signal transmission, reduces signal interference and loss, and allows for easy creation of complex pattern designs, including curves, corners, and multi-layer structures. This improves the integration of metal layer traces, reduces space requirements, and enhances equipment performance and reliability.

[0129] In one possible embodiment, the via 140 is filled with cured adhesive.

[0130] Therefore, the curing adhesive can effectively fill the via 140, isolating the metal layer traces within the via 140 from the surrounding environment, thus enhancing insulation performance. The curing adhesive can reduce electromagnetic coupling between the metal layer traces within the via 140 and the surrounding environment, thereby reducing signal interference. Furthermore, the curing adhesive filling the via 140 can completely fill the space of the via 140, forming a sealed barrier to prevent moisture from seeping into the interior of the smart wearable device 1 through the via 140, effectively preventing water leakage caused by the via 140, thereby improving the waterproof performance of the smart wearable device.

[0131] The curing adhesive can be made of epoxy resin, polyurethane, silicone, acrylic, or other similar materials, and is not limited to any particular type.

[0132] In one possible embodiment, the metal layer traces on the middle frame bracket 100 are covered with a waterproof layer except at the contact points with the first conductive contact 340 and the second conductive contact 210.

[0133] Therefore, the waterproof layer can effectively block the entry of external moisture and protect the metal layer wiring from water corrosion. During the use of the smart wearable device 1, it may come into contact with water sources such as sweat and rain. The waterproof layer can ensure that the metal layer wiring will not be short-circuited or damaged due to moisture.

[0134] The waterproof layer can be a polytetrafluoroethylene (PTFE) coating, a waterproof membrane, or a sprayed coating applied directly to the metal layer traces except at the contact points with the first conductive contact 340 and the second conductive contact 210. No specific limitation is made here.

[0135] In one possible embodiment, the metal top cover 300 is fixed to the middle frame bracket 100 with adhesive dots.

[0136] Therefore, adhesive application can form a sealing layer at the connection between the metal top cover 300 and the middle frame bracket 100, preventing moisture, dust and other impurities from entering the interior of the smart wearable device 1, thus improving waterproof performance. Moreover, adhesive application is relatively simple and quick, and can be carried out efficiently on the production line. Compared with traditional mechanical connection methods, adhesive application does not require complex parts and assembly tools, reducing assembly steps and time, and improving production efficiency.

[0137] In one possible embodiment, see Figure 2 The smart wearable device 1 also includes a decorative element 800 stacked on the metal cover 300, which is fixed to the metal cover 300 by adhesive dots.

[0138] Therefore, the decorative part 800 can not only add a unique visual effect and personalized elements to the smart wearable device 1, but also provide a certain degree of protection for the metal cover 300. The glue fixation can ensure that there are no obvious gaps or gaps between the decorative part 800 and the metal cover 300, thereby maintaining the integrity of the device's appearance design.

[0139] The decorative part 800 can be made of any material, such as ceramic or plastic, and is not limited here.
