[0003] Current smartwatches generally use a sealing ring between the back cover and the watch body to achieve a waterproof seal. However, due to factors such as the shrinkage or aging of the sealing material when exposed to cold, the sealing structure may fail after long-term use, resulting in a reduced lifespan of the smartwatch. Utility Model Content

[0004] The main purpose of this invention is to propose a smartwatch that aims to improve the lifespan of the smartwatch.

[0005] To achieve the above objectives, the smartwatch proposed in this utility model includes: The watch body has a receiving groove, which includes a mounting section, a sealing section, and a connecting section connected in sequence. The mounting section is used to accommodate various electronic components. The sealing section is gradually tapered along the connecting section toward the mounting section. A back cover, detachably connected to the inner peripheral wall of the connecting section and extending into the sealing section; and A sealing ring is sandwiched between the back cover and the inner peripheral wall of the sealing section.

[0006] In one embodiment, the inner diameter of the end of the mounting section near the sealing section is defined as L1, and the minimum inner diameter of the sealing section is L2; ​​the inner diameter of the sealing ring is l1, and the outer diameter of the sealing ring is l2; L2-L1≥l2-l1.

[0007] In one embodiment, a stop ring is provided protruding from the periphery of the mounting section near the sealing section, and the stop ring extends along the axial direction of the receiving groove.

[0008] In one embodiment, the smartwatch further includes a water-absorbing ring disposed on the periphery of the mounting section near the sealing section, with one end of the water-absorbing ring facing away from the mounting section abutting against the sealing ring.

[0010] In one embodiment, the absorbent ring and the sealing section enclose each other to form a limiting groove, and the sealing ring is locked within the limiting groove.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0023] In existing technologies, smartwatches, as wearable devices, have achieved a combination of functions such as location tracking to prevent loss, electronic payment, and health monitoring. Traditional waterproof sealing solutions rely on a single sealing ring structure between the back cover and the watch body. However, the sealing material is prone to gaps after low-temperature shrinkage or long-term aging, leading to a gradual decline in waterproof performance and affecting the lifespan of the device.

[0024] To address the aforementioned problems, this utility model proposes a smartwatch 100. Figure 1 , Figure 2, Figure 3 as well as Figure 4 A schematic diagram of the structure of an embodiment of the smartwatch 100 provided by this utility model.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 This utility model proposes a smart watch 100, including a watch body 1, a back cover 2, and a sealing ring 3; the watch body 1 forms a receiving groove 1a, the receiving groove 1a includes a mounting section 1a1, a sealing section 1a2, and a connecting section 1a3 connected in sequence, the mounting section 1a1 is used to accommodate various electronic components; the sealing section 1a2 is gradually tapered along the connecting section 1a3 toward the mounting section 1a1; the back cover 2 is detachably connected to the inner peripheral wall of the connecting section 1a3 and extends into the sealing section 1a2; the sealing ring 3 is sandwiched between the back cover 2 and the inner peripheral wall of the sealing section 1a2.

[0026] The mounting section 1a1 of the receiving groove 1a refers to the cavity structure that carries the electronic components. Specifically, it can be implemented using a stepped cylindrical cavity, with its axial dimension larger than the total height of the electronic components to reserve assembly space. The sealing section 1a2 refers to a transition area with a tapered contraction feature, specifically implemented using a frustum-shaped conical structure, used to guide the sealing ring 3 to generate radial compression deformation. The connecting section 1a3 refers to the interface area that forms a mechanical connection with the back cover, specifically implemented using a threaded cylindrical structure, used to establish a detachable mechanical lock. The detachable connection between the back cover and the connecting section 1a3 refers to repeated assembly and disassembly through threaded engagement or snap-fit ​​structures, such as providing external threads on the outer wall of the back cover to match the internal threads of the connecting section 1a3. The sealing ring 3 being sandwiched between the back cover and the sealing section 1a2 means that the elastic element simultaneously contacts the outer wall of the back cover and the inner wall of the sealing section 1a2, for example, using an O-ring rubber ring to form a radial compression seal within the tapered space.

[0027] Specifically, mounting section 1a1 provides space for fixing electronic components, while sealing section 1a2 guides the sealing ring 3 to generate pre-compression through a tapered structure. When the back cover is screwed into connecting section 1a3, its outer wall pushes the sealing ring 3 along the conical surface of sealing section 1a2, forcing the sealing ring 3 to expand radially and fill the gap between the back cover and sealing section 1a2. As temperature changes cause material contraction, the contact pressure between the conical surface of sealing section 1a2 and the sealing ring 3 automatically increases due to structural contraction, forming a dynamic compensating seal. When the back cover is removed, the sealing ring 3 automatically disengages from the conical surface contact due to elastic restoring force, avoiding secondary damage caused by adhesion.

[0028] Through the synergistic effect of the conical sealing section 1a2 and the detachable back cover, the sealing ring 3 undergoes controllable pre-compression during assembly, and automatically enhances the sealing pressure through structural space changes when the material shrinks. This structural compensation mechanism breaks through the technical route of simply relying on material performance, significantly improving the environmental adaptability of the sealing system, thereby effectively solving the problem of decreased waterproof performance caused by the shrinkage of the sealing material. In high temperature and high humidity or low temperature and dry environment, the conical structure of the sealing section 1a2 guides the sealing ring 3 to produce adaptive deformation, continuously maintaining the contact pressure at the sealing interface; the detachable back cover design facilitates the periodic replacement of the sealing ring 3, avoiding overall seal failure due to material aging, and extending the service life of the smartwatch 100 under complex working conditions.

[0029] Please refer to Figure 2 and Figure 3 In one embodiment of this utility model, the inner diameter of the end of the mounting section 1a1 near the sealing section 1a2 is defined as L1, the minimum inner diameter of the sealing section 1a2 is L2; ​​the inner diameter of the sealing ring 3 is l1, and the outer diameter of the sealing ring 3 is l2; L2-L1≥l2-l1.

[0030] In this design, the inner diameter L1 of the mounting section 1a1 near the sealing section 1a2 refers to the diameter of the circular cross-section at the connection between the mounting section 1a1 and the sealing section 1a2, which can be achieved by machining a stepped cross-section structure. The minimum inner diameter L2 of the sealing section 1a2 refers to the diameter of the narrowest part of the annular channel formed after the sealing section 1a2 contracts, which can be achieved through a tapered structure design to guide the compression deformation direction of the sealing ring 3. The inner diameter l1 and outer diameter l2 of the sealing ring 3 refer to the inner and outer diameters of the sealing ring 3 in its natural state, respectively, which can be achieved by molding rubber material to fill the gap between the back shell and the sealing section 1a2 under compression.

[0031] Specifically, when the back cover is installed into the connecting section 1a3, the sealing ring 3 is subjected to radial compression from the inner circumferential wall of the sealing section 1a2. Since the difference between the minimum inner diameter L2 of the sealing section 1a2 and the inner diameter L1 of the mounting section 1a1 is greater than or equal to the difference between the inner and outer diameters of the sealing ring 3, the radial compression of the sealing ring 3 is absorbed by the dimensional difference of the receiving section during the screwing-in of the back cover. Thus, the sealing ring 3 can generate sufficient elastic deformation to achieve a seal while avoiding permanent deformation or stress relaxation due to excessive compression.

[0032] By defining the dimensional relationship of the receiving groove 1a, structural space is reserved for the compression deformation of the sealing ring 3. This design allows the sealing ring 3 to compensate for the deformation allowance through dimensional differences when subjected to temperature changes or material aging during long-term use, thereby maintaining a stable sealing pressure. This solves the sealing failure problem caused by insufficient or excessive compression in traditional sealing structures, effectively improving the waterproof reliability of the smartwatch 100 in complex usage environments and extending the service life of the sealing components.

[0033] Please refer to Figure 3 In one embodiment of the present invention, a stop ring 1a11 is provided on the periphery of the mounting section 1a1 near the sealing section 1a2, and the stop ring 1a11 extends along the axial direction of the receiving groove 1a.

[0034] The stop ring 1a11 is an annular protrusion structure located at the junction of the mounting section 1a1 and the sealing section 1a2. It can be integrally molded with the body 1 using injection molding. Its function is to form a physical barrier to limit the axial displacement of electronic components within the mounting section 1a1. Axial extension means that the extension direction of the stop ring 1a11 is parallel to the central axis of the receiving groove 1a. This can be achieved using a cylindrical or prismatic structure. This axially extending layout effectively limits the lateral movement of electronic components.

[0035] Specifically, when the back cover and the watch body 1 are assembled, the stop ring 1a11 is positioned in the transition area between the mounting section 1a1 and the sealing section 1a2. After the electronic component is installed into the mounting section 1a1, the annular protrusion structure of the stop ring 1a11 axially limits the electronic component, preventing it from moving towards the sealing section 1a2 due to vibration or external force. Because the stop ring 1a11 extends axially along the receiving groove 1a, it prevents contact friction between the electronic component and the sealing ring 3 during the screwing of the back cover into the connecting section 1a3, thereby maintaining the integrity and sealing performance of the sealing ring 3.

[0036] By adding an axially extending stop ring 1a11, a rigid constraint is formed on the electronic components, effectively eliminating the impact of displacement on the sealing structure. This prevents axial displacement of the electronic components within the mounting section 1a1, avoiding sealing failure of the sealing ring 3 due to uneven pressure. Simultaneously, the rigid limiting structure reduces the wear risk of the sealing ring 3, thereby improving the waterproof reliability of the smartwatch 100 during long-term use. This structure achieves its function without adding extra assembly steps, maintaining the removable and maintainable back cover.

[0037] Please refer to Figure 3In one embodiment of the present invention, the smartwatch 100 further includes a water-absorbing ring 4, which is disposed on the periphery of the mounting section 1a1 near the sealing section 1a2, and the end of the water-absorbing ring 4 facing away from the mounting section 1a1 abuts against the sealing ring 3.

[0038] The absorbent ring 4 refers to a ring-shaped structure with water-absorbing function, which can be made of superabsorbent resin material to absorb moisture that seeps in from the sealing ring 3. "Abutting against the sealing ring 3" means that the absorbent ring 4 and the sealing ring 3 form physical contact, which can be achieved by adjusting the thickness and elasticity of the absorbent ring 4 to ensure a tight fit between them.

[0039] Specifically, the absorbent ring 4 is positioned at the periphery of the junction between the mounting section 1a1 and the sealing section 1a2, with its end furthest from the mounting section 1a1 directly contacting the sealing ring 3. When external moisture seeps in through the gap in the sealing ring 3, the absorbent ring 4 absorbs and stores the moisture using its material properties, preventing further diffusion into the mounting section 1a1. Simultaneously, the contact between the absorbent ring 4 and the sealing ring 3 forms an auxiliary sealing barrier, further reducing the risk of moisture penetration.

[0040] A water-absorbing ring 4 is added to the outside of the sealing ring 3, forming a dual protection mechanism of physical sealing and water absorption barrier. Even if the sealing ring 3 develops tiny gaps due to aging or temperature changes, the water-absorbing ring 4 can still continuously absorb the seeping water, preventing electronic components from being damaged by moisture. This effectively solves the problem of water seeping into the electronic component area due to the failure of the sealing ring 3, significantly improving the waterproof reliability of the smartwatch 100 in complex usage environments and extending the service life of the internal electronic components.

[0041] Please refer to Figure 3 In one embodiment of this utility model, the water-absorbing ring 4 is snapped between the stop ring 1a11 and the sealing section 1a2.

[0042] Among them, snap-fit ​​refers to fixing through structural fit, which can be achieved by concave-convex fit or elastic deformation, so that the water absorption ring 4 is compressed and fixed in the gap formed by the stop ring 1a11 and the sealing section 1a2.

[0043] Specifically, the stop ring 1a11 extends axially along the receiving groove 1a to form an annular protrusion, creating a clamping space with the inner wall of the sealing section 1a2. After the water-absorbing ring 4 is pressed into this space, its upper and lower end faces contact the top of the stop ring 1a11 and the inner wall of the sealing section 1a2, respectively, while its circumferential sidewalls form an interference fit with the outer surface of the stop ring 1a11 and the inner surface of the sealing section 1a2. Thus, the water-absorbing ring 4 is constrained in both the axial and radial directions, preventing displacement due to vibration or temperature changes.

[0044] The stop ring 1a11 and the sealing section 1a2 form a bidirectional limiting structure, which significantly enhances the assembly stability of the water absorption ring 4, effectively prevents the water absorption ring 4 from loosening or falling off during long-term use, ensures that the water absorption material is always in the predetermined position, and continuously absorbs the trace amount of water vapor that seeps into the sealing section 1a2, thus avoiding damage to electronic components due to moisture.

[0045] Please refer to Figure 3 In one embodiment of this utility model, the water-absorbing ring 4 and the sealing section 1a2 enclose each other to form a limiting groove 4a, and the sealing ring 3 is locked and limited within the limiting groove 4a.

[0046] The limiting groove 4a refers to the annular groove structure formed by the water-absorbing ring 4 and the inner peripheral wall of the sealing section 1a2. Specifically, this can be achieved by leaving a gap between the end face of the water-absorbing ring 4 and the inner wall of the sealing section 1a2. This structure provides axial and radial positioning space for the sealing ring 3. The snap-fit ​​limiting refers to the sealing ring 3 being embedded into the limiting groove 4a through an interference fit or elastic deformation. Specifically, this can be achieved by the rubber sealing ring 3 expanding under pressure and forming a frictional lock with the groove wall. This feature prevents the sealing ring 3 from axial displacement after assembly.

[0047] Specifically, during the process of the back cover being screwed into the connecting section 1a3 of the body 1, the sealing ring 3 undergoes radial expansion due to the compression of the back cover. At this time, the limiting groove 4a formed by the water-absorbing ring 4 and the inner wall of the sealing section 1a2 provides three-dimensional constraint on the sealing ring 3. When the back cover is fully assembled, the elastic restoring force of the sealing ring 3 causes its outer surface to form a continuous pressing state with the inner wall of the limiting groove 4a. At the same time, the rigid support surface of the water-absorbing ring 4 can prevent the sealing ring 3 from moving towards the installation section 1a1. This structure allows the sealing ring 3 to maintain a stable sealing contact pressure under temperature changes or mechanical vibration conditions, while the water-absorbing ring 4 absorbs the infiltrated water vapor and also serves as a rigid boundary layer for the limiting groove 4a.

[0048] The mechanical limiting structure formed by the limiting groove 4a constrains the sealing ring 3 in three orthogonal directions, completely restricting its displacement freedom. At the same time, the water-absorbing ring 4 serves both a positioning function and an auxiliary moisture-proof function, forming a multi-protection mechanism. This effectively solves the sealing failure problem caused by material creep or assembly stress relaxation of the sealing ring 3. Through the synergistic effect of the limiting groove 4a and the water-absorbing ring 4, the sealing interface maintains a constant contact pressure throughout the entire life cycle of the smartwatch 100, while inhibiting the erosion of the sealing material by moisture, thus achieving long-term stability of the sealing performance.

[0049] Please refer to Figure 2 In one embodiment of the present invention, the smartwatch 100 further includes thermally conductive silicone 5, which is disposed on the back cover 2 and located within the mounting section 1a1; the thermally conductive silicone 5 is configured to contact each electronic component.

[0050] Among them, thermally conductive silicone 5 refers to a flexible colloidal material with thermal conductivity. Specifically, it can be achieved by adding thermally conductive fillers to a silicone-based polymer, used to establish a heat conduction path between the electronic components and the back cover. This material fills the gaps between the electronic components and the back cover, quickly transferring the heat generated by the electronic components to the back cover, thereby reducing the operating temperature of the components. Electronic components refer to the functional modules in the smartwatch 100 that generate heat, specifically components such as processors, batteries, or sensors. These components generate heat during operation due to energy conversion.

[0051] Specifically, the thermally conductive silicone 5 is pre-installed on the side of the back cover facing the mounting section 1a1. After the back cover and the body 1 are assembled, the thermally conductive silicone 5 deforms under the pressure of the electronic components within the mounting section 1a1, tightly adhering to the surface of the electronic components. Heat is transferred from the electronic components to the back cover through the conduction path of the thermally conductive silicone 5. The back cover, as a component made of metal or a highly thermally conductive material, dissipates the heat to the external environment. During this process, the flexibility and compressibility of the thermally conductive silicone 5 ensure sufficient contact with electronic components of different heights, avoiding a decrease in heat conduction efficiency due to assembly tolerances.

[0052] By introducing thermally conductive silicone 5 to fill the gaps, a continuous heat conduction interface is formed. Compared with traditional heat dissipation methods, heat can be more efficiently dissipated from internal components, reducing the accumulation of heat in the sealed space. This reduces the risk of component performance degradation or sealing material aging caused by high temperature, effectively solving the problem of temperature rise caused by insufficient heat dissipation of internal electronic components of the smartwatch 100. Through the active heat conduction mechanism of thermally conductive silicone 5, the working stability of components is improved and the service life is extended. At the same time, the negative impact of heat on the sealing structure is reduced, enhancing overall reliability.

[0053] In one embodiment of this utility model, the absorbent element is made of superabsorbent resin.

[0054] Superabsorbent polymer (SAP) is a polymer material capable of absorbing and locking in large amounts of moisture. It can be made from polyacrylates or starch graft copolymers. Its molecular structure contains hydrophilic groups and a cross-linked network, enabling it to rapidly absorb water and swell through osmotic pressure and capillary action. In this technical solution, this material is used to form the absorbent ring 4, which absorbs residual moisture inside the sealing section 1a2 or moisture seeping in from the outside, preventing moisture from contacting electronic components and thus preventing seal failure due to shrinkage or aging of the sealing material.

[0055] Specifically, the absorbent ring 4 is positioned on the periphery of the mounting section 1a1 near the sealing section 1a2, with one end abutting against the sealing ring 3. When gaps appear in the sealing section 1a2 due to temperature changes or material aging, external moisture may seep into the mounting section 1a1 area through these gaps. At this time, the absorbent ring 4, made of superabsorbent resin, quickly absorbs moisture and expands, filling the gaps formed by the contraction of the sealing ring 3. Simultaneously, the expanded volume further compresses the contact surface between the sealing ring 3 and the sealing section 1a2, enhancing the sealing effect. Furthermore, the superabsorbent resin forms a gel-like substance after absorbing water, maintaining a water-locking state for a long time and preventing secondary moisture release.

[0056] Compared to existing technologies, traditional smartwatches typically use a single elastic material such as rubber as a seal. Such materials are prone to forming water seepage channels after shrinking in cold or aging over a long period of time, and they lack the ability to actively absorb water. In contrast, this application introduces a highly absorbent resin material, enabling the water-absorbing ring 4 to not only have an elastic sealing function, but also to actively absorb and fix the seeping water, forming a dual protection mechanism.

[0057] Through the above technical solution, this application effectively solves the problem of sealing failure caused by shrinkage or aging of sealing material. By using the active water absorption and expansion characteristics of the water absorption ring 4, the sealing section 1a2 and the back shell are continuously kept in close contact, thereby extending the waterproof performance and service life of the smartwatch 100.

[0058] In one embodiment of this utility model, the inner peripheral wall of the connecting section 1a3 is formed with an internal thread, the back cover 2 is formed with an external thread, and the back cover 2 is threadedly connected to the watch body 1.

[0059] Specifically, when the back cover is inserted into the body 1 by rotation, the meshing motion of the external and internal threads generates an axial clamping force, ensuring tight contact between the back cover and the inner circumferential wall of the connecting section 1a3. The helix angle design of the thread structure controls the axial displacement during the screwing process, thereby ensuring that the sealing ring 3 between the back cover and the sealing section 1a2 is uniformly compressed. During assembly, the preload generated by the thread meshing can counteract the shrinkage or expansion of the sealing material caused by temperature changes, maintaining the stability of the sealing interface.

[0060] The mechanical preload generated by the threaded connection forms a double sealing mechanism. The threaded meshing structure not only provides a stable axial clamping force, but also compensates for the sealing pressure by tightening the back shell when the sealing ring 3 ages. Compared with the structure that relies solely on the sealing ring, it has higher reliability. This effectively maintains the sealing interface pressure between the back shell and the body 1, preventing sealing failure caused by shrinkage or aging of the sealing material. At the same time, the threaded connection structure is easy to disassemble and maintain and has a self-locking function, which can maintain connection stability in long-term vibration environments.

[0061] In one embodiment of this utility model, the sealing element is made of rubber.

[0062] Rubber refers to a polymer material with elasticity and aging resistance. Specifically, it can be made of nitrile rubber or silicone rubber. The elasticity of rubber can compensate for shrinkage caused by temperature changes, and its aging resistance can reduce the degradation of material properties during long-term use.

[0063] Specifically, the sealing ring 3 is made of rubber and forms an elastic contact between the back cover and the inner peripheral wall of the sealing section 1a2. When the back cover is connected to the body 1, the rubber sealing ring 3 is deformed under pressure, filling the gap between the back cover and the sealing section 1a2. The elasticity of the rubber allows it to maintain the contact pressure with the inner peripheral wall of the sealing section 1a2 even after low-temperature shrinkage or long-term use, thereby delaying the sealing failure caused by material shrinkage or aging.

[0064] Compared to existing technologies, existing sealing ring materials are prone to losing elasticity at low temperatures or after aging, leading to an expansion of the sealing gap. In contrast, the rubber sealing ring 3, with its elasticity and aging resistance, can adapt to temperature fluctuations and slow down performance degradation, reducing the risk of sealing structure failure. Through the above technical solution, this application can extend the service life of the sealing structure, reduce liquid ingress problems caused by sealing failure, while also reducing maintenance frequency and costs, and improving the long-term reliability of the smartwatch 100.

[0065] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
