[0004] In existing technologies, antenna grounding requires multiple welding steps, specifically welding the spring clip to the pre-researched steel sheet, welding the conductive steel sheet to the pre-pressed steel sheet, and then welding the conductive steel sheet to the mid-frame decorative component. This process not only increases production costs but also reduces production efficiency. The complexity of the welding process leads to a high defect rate, affecting the overall quality and reliability of the product. Furthermore, the numerous welding points make product repair and maintenance difficult, increasing after-sales service costs. Utility Model Content

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] Please refer to the following: Figure 1 and Figure 2The grounding structure of the antenna 200 provided in this application embodiment will now be described. This grounding structure includes a middle frame 100, an antenna 200, a metal decorative element 300, and an elastic conductive element 400. The antenna 200 is embedded within the middle frame 100 and partially exposed on the surface of the middle frame 100. The metal decorative element 300 is snapped into place with the middle frame 100. The elastic conductive element 400 is disposed between the antenna 200 and the metal decorative element 300. By pressing the elastic conductive element 400, the antenna 200, the elastic conductive element 400, and the metal decorative element 300 are electrically connected.

[0032] The antenna 200 grounding structure provided in this application, compared with the prior art, abandons the traditional steel sheet welding design. It uses an elastic conductive element 400 to connect the antenna 200 and the metal decorative element 300, achieving electrical conductivity through compression, thus ensuring the grounding function of the antenna 200. This design greatly simplifies the process, reduces welding steps, thereby lowering production costs and improving production efficiency. Simultaneously, due to the reduction in welding points, the defect rate is significantly reduced, improving the overall quality and reliability of the product. Furthermore, this structure is simpler in terms of product repair and maintenance, reducing after-sales service costs. The adoption of this antenna 200 grounding structure in wearable electronic devices can effectively overcome the shortcomings of the prior art, improve product performance, and bring a better user experience.

[0033] In one embodiment of this application, the compression of the elastic conductive element 400 is greater than or equal to 50%.

[0034] In this embodiment, the high compression amount enables the elastic conductive element 400 to maintain good elastic deformation capability when subjected to a certain external force, thereby maintaining a stable electrical conduction state between the antenna 200, the elastic conductive element 400, and the metal decorative element 300. Even when the wearable electronic device is affected by external factors such as vibration and collision, the elastic conductive element 400, with its large compression amount, can still effectively prevent the antenna 200 from failing due to poor contact, further enhancing the stability and reliability of the antenna 200 grounding structure. This ensures that the wearable electronic device can stably achieve the grounding function of the antenna 200 under various complex usage scenarios, providing a solid guarantee for the signal transmission and other performance of the device.

[0035] Understandably, if the compression of the elastic conductive element 400 is less than 50%, it will affect the conductivity between the antenna 200 and the metal decorative element 300, resulting in poor performance of the antenna 200. When subjected to external forces, it may not be able to generate sufficient elastic deformation to maintain good contact, easily leading to an interruption in the electrical conduction between the antenna 200 and the metal decorative element 300. This, in turn, affects the grounding effect of the antenna 200, causing interference with the signal transmission of the wearable device, reducing its performance, and failing to meet users' needs for stable operation in different environments. Therefore, ensuring that the compression of the elastic conductive element 400 is greater than or equal to 50% is crucial for guaranteeing the grounding structure of the antenna 200 and the performance of the wearable device.

[0036] In one embodiment of this application, the elastic conductive element 400 is conductive silicone or conductive rubber.

[0037] In this embodiment, conductive silicone possesses excellent flexibility and conductivity, enabling it to undergo significant elastic deformation under external force. This ensures a consistently strong electrical connection between the antenna 200 and the metal decorative component 300, effectively meeting the grounding requirements of the antenna 200. Simultaneously, conductive silicone exhibits good corrosion resistance and high-temperature resistance, making it suitable for use in various environments and less susceptible to environmental factors affecting its conductivity and elasticity. Conductive rubber also possesses excellent elasticity and conductivity. Its material properties allow it to provide a stable conductive path for the antenna 200 grounding under diverse and complex usage scenarios, and it can withstand a certain degree of friction and vibration, ensuring the long-term stability of the antenna 200 grounding structure. Furthermore, conductive rubber has a relatively low cost, which is beneficial for cost control during large-scale production of wearable electronic devices, thereby enhancing the product's market competitiveness.

[0038] In another embodiment of this application, the elastic conductive element 400 can also be made of other materials with good conductivity and elasticity, such as conductive plastic. Under certain process requirements, conductive plastic can achieve functions similar to conductive silicone and conductive rubber, providing an effective connection for the grounding of the antenna 200. Conductive plastic is highly malleable and can be made into various shapes according to different design needs to adapt to different spatial layouts in the grounding structure of the antenna 200, satisfying diverse product designs. At the same time, some conductive plastics are also lightweight, which is a significant advantage for wearable electronic devices that pursue lightweight design. It can further reduce the overall weight of the device and improve user comfort without affecting the grounding performance of the antenna 200.

[0039] In one embodiment of this application, the elastic conductive element 400 is in the shape of a cuboid.

[0040] In this embodiment, the cuboid-shaped elastic conductive element 400 has a large contact area, allowing it to better fit with the antenna 200 and the metal decorative element 300, further enhancing conductivity and ensuring the stability of the antenna 200's grounding. Furthermore, the cuboid structure facilitates processing and installation during manufacturing, and its regular shape allows for efficient layout within a limited space, avoiding excessive space occupation or installation inconvenience due to overly complex shapes. When subjected to compression, the elastic conductive element 400 exhibits relatively uniform force on all surfaces, effectively maintaining its elasticity and conductivity. Even after repeated compression, it maintains good grounding performance, providing reliable grounding protection for the antenna 200 of the wearable electronic device.

[0041] Specifically, the elastic conductive element 400 can be designed to be 2*1*1mm in size. In actual production, this size avoids compromising conductivity due to excessively small size, while also preventing cost increases or spatial layout difficulties due to excessively large size. This size design is compatible with the compact internal structure of wearable electronic devices, making the entire antenna 200 grounding structure more compact and practical. Furthermore, considering the varying grounding performance requirements of different wearable electronic device models, the size of the elastic conductive element 400 can be fine-tuned to achieve optimal grounding performance. Through careful design of the shape and size of the elastic conductive element 400, the antenna 200 grounding structure is further optimized, improving the overall performance of the wearable electronic device.

[0042] In one embodiment of this application, please refer to the following: Figure 1 and Figure 3 The grounding structure of antenna 200 also includes a waterproof component 500, which is disposed between the middle frame 100 and the metal decorative component 300 and surrounds the elastic conductive component 400.

[0043] In this embodiment, the waterproof component 500 effectively prevents external moisture from entering the electronic wearable device, preventing moisture from corroding the elastic conductive component 400 and other electronic components, thereby affecting the grounding effect of the antenna 200 and the normal operation of the device. Its arrangement around the elastic conductive component 400 provides all-around protection, ensuring that the elastic conductive component 400 can stably maintain its elasticity and conductivity in various humid environments, guaranteeing that the antenna 200 grounding structure is always in good working condition, and further improving the reliability and stability of the electronic wearable device.

[0044] In one embodiment of this application, the waterproof component 500 is provided with a clearance through hole, and the elastic conductive component 400 is located in the clearance through hole.

[0045] In this embodiment, the avoidance through-hole design ensures both the normal installation and operation of the elastic conductive component 400 and allows the waterproof component 500 to fit tightly around the elastic conductive component 400, achieving a good waterproof effect. This design avoids interference from the waterproof component 500 with the normal function of the elastic conductive component 400, ensuring that the elastic conductive component 400 can expand, contract, and conduct current without hindrance. Simultaneously, by rationally designing the size and shape of the avoidance through-hole, it can better fit the elastic conductive component 400, ensuring the precision of the fit between the two, further improving the synergistic efficiency of waterproof and grounding performance, and providing strong support for the stable operation of wearable electronic devices in complex environments.

[0046] In one embodiment of this application, the size of the clearance through hole is larger than the size of the elastic conductive element 400.

[0047] In this embodiment, the larger clearance through-hole provides sufficient space for the elastic conductive component 400 to move, allowing for adequate buffering when the wearable device experiences stress due to movement or deformation. This prevents damage to the elastic conductive component 400 due to space constraints, thus ensuring its conductivity and elasticity. Furthermore, this size design facilitates the installation and removal of the elastic conductive component 400, making maintenance or replacement easier and improving the maintainability of the wearable device. Simultaneously, the reasonable size difference further optimizes the waterproofing effect, creating a better seal between the waterproof component 500 and the elastic conductive component 400, effectively preventing moisture intrusion and ensuring the long-term stable operation of the antenna 200 grounding structure in humid environments.

[0048] In one embodiment of this application, the waterproof component 500 is a waterproof foam or a sealing ring.

[0049] In this embodiment, the waterproof foam possesses excellent elasticity and sealing properties, effectively filling gaps and preventing moisture from entering the grounding structure of the antenna 200. Its soft texture allows it to conform well to the surfaces of the elastic conductive element 400 and other components, adapting to installation locations of different shapes and sizes. Even when the wearable device is subjected to a certain degree of bending or deformation, it maintains good waterproof performance. The sealing ring, typically made of materials such as rubber, offers excellent sealing performance and high resistance to aging and corrosion. During long-term use, it is not easily affected by external environmental factors, providing durable and stable waterproof protection for the antenna 200 grounding structure. Both the waterproof foam and the sealing ring, when used as waterproof components 500 in the antenna 200 grounding structure, work in conjunction with components such as the elastic conductive element 400 to ensure reliable operation of the wearable device in various complex environments, guaranteeing the effective performance of its waterproof and grounding capabilities.

[0050] In one embodiment of this application, antenna 200 is an LDS antenna.

[0051] In this embodiment, LDS stands for Laser-Direct-Structuring. This technology can directly generate metal circuits on injection-molded plastic parts using laser engraving, making the manufacturing process of antenna 200 more precise, efficient, and flexible. Using an LDS antenna can effectively improve the performance of the antenna 200's grounding structure. For example, it allows for more complex antenna shapes and layouts to meet the compact and diverse design requirements of wearable electronic devices. Furthermore, LDS antennas possess excellent conductivity and stability, which helps improve the signal reception and transmission quality of wearable electronic devices, providing users with a smoother communication experience.

[0052] This application also provides an electronic wearable device, which includes the above-described antenna 200 grounding structure.

[0053] In this embodiment, wearable electronic devices can encompass various types, including smartwatches, smart bracelets, and head-mounted devices. Taking a smartwatch as an example, after integrating the antenna 200 grounding structure, in daily wearing scenarios, whether it's washing hands, getting wet in the rain, or in various complex electromagnetic environments, the stable waterproof and grounding performance of the antenna 200 grounding structure ensures a stable and efficient communication connection between the watch and the outside world. When users use the smartwatch for functions such as phone calls, message pushes, and real-time location tracking, there will be no signal interruptions or data transmission errors due to waterproofing or grounding issues, greatly improving the user experience and reliability of wearing electronic devices.

[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
