Description

Technical Field

[0001] This utility model relates to the field of watch technology, and in particular to a sports watch. Background Technology

[0002] Sports watches are wearable devices that support sports monitoring functions such as running, cycling, swimming, and fitness. They feature waterproof, shockproof, GPS positioning, and heart rate measurement technologies, and are made of materials such as stainless steel, titanium alloy, and carbon fiber.

[0003] With the miniaturization of electronic components, sports watches are integrating more and more functional components, such as accelerometers, barometers, and photoelectric sensors, enabling functions such as step counting, altitude measurement, photoplethysmography (PPG) heart rate monitoring, and some models are also equipped with ECG sensors to improve data accuracy.

[0004] With the increasing integration of functional components, heat dissipation has become a new challenge for sports watches. Current technology typically incorporates ventilation holes on the watch body to connect to the outside environment and accelerate heat dissipation. However, sweat is produced on the user's skin during exercise, and this sweat may enter the watch through these ventilation holes, causing short circuits in internal components and ultimately reducing the watch's lifespan. Utility Model Content

[0005] The main purpose of this invention is to propose a sports watch that aims to improve the lifespan of the sports watch while ensuring heat dissipation.

[0006] To achieve the above objectives, the present invention provides a sports watch comprising: The watch body has a mounting cavity for mounting various functional components; the peripheral wall of the mounting cavity has multiple heat dissipation holes; each heat dissipation hole includes a communicating inlet and outlet, the inlet being located on the inner peripheral wall of the mounting cavity, and the outlet being located on the outer peripheral wall of the mounting cavity; the inlet and the outlet are offset from each other; and Multiple absorbent elements are provided, each of which is arranged around the inner peripheral wall of one of the heat dissipation holes and close to the inlet, to absorb the liquid entering the mounting cavity from the heat dissipation hole.

[0007] In one embodiment, the heat dissipation hole includes a first heat dissipation section and a second heat dissipation section that are connected to each other; the first heat dissipation section is connected to the mounting cavity, and the inlet is located at the end of the first heat dissipation section away from the second heat dissipation section; the second heat dissipation section is used to connect to the outside, and the outlet is located at the end of the second heat dissipation section away from the first heat dissipation section; the water absorption element is connected to the inner wall of the first heat dissipation section; the first heat dissipation section and the second heat dissipation section are staggered.

[0008] In one embodiment, a straight line extending along the central axis of the first heat dissipation section is arranged parallel to a straight line extending along the central axis of the second heat dissipation section.

[0009] In one embodiment, the heat dissipation hole further includes a third heat dissipation section, the first and second heat dissipation sections being connected at their respective ends; the angle between a straight line extending along the central axis of the third heat dissipation section and a straight line extending along the central axis of the second heat dissipation section is defined as α, where 130°≤α≤140°.

[0010] In one embodiment, the body includes a front shell and a rear cover, the front shell and the rear cover are detachably connected and enclose the mounting cavity; each of the heat dissipation holes is opened in the front shell, and each of the water absorption components is detachably connected to the rear cover.

[0011] In one embodiment, the front cover and the rear cover are snapped together; the front cover has multiple insertion holes, each insertion hole connecting to a heat dissipation hole, and each water-absorbing element passes through one insertion hole and extends into the corresponding heat dissipation hole. In one embodiment, In one embodiment, the absorbent element is snapped onto the rear cover.

[0012] In one embodiment, the sports watch further includes a heat sink disposed within the mounting cavity and abutting against the watch body; the heat sink is used to mount each of the functional elements.

[0013] In one embodiment, the absorbent element is made of superabsorbent resin.

[0014] In this invention, a sports watch includes a watch body and multiple water-absorbing components. The watch body has a mounting cavity for mounting various functional components. Multiple heat dissipation holes are formed in the peripheral wall of the mounting cavity. Each heat dissipation hole includes a connected inlet and outlet. The inlet is located on the inner peripheral wall of the mounting cavity, and the outlet is located on the outer peripheral wall. The inlet and outlet are staggered. Each water-absorbing component is arranged around the inner peripheral wall of a heat dissipation hole and close to the inlet to absorb liquid entering the mounting cavity from the heat dissipation hole. In this invention, when external liquid enters the heat dissipation hole from the outlet, because the inlet and outlet are staggered, the liquid needs to change its flow direction to reach the inlet. The droplets are highly likely to collide with the hole wall due to inertia at the turning point, thus flowing along the hole wall. The water-absorbing component, located close to the inlet and surrounding the inner peripheral wall of the heat dissipation hole, can promptly absorb the liquid adhering to the hole wall. Simultaneously, the airflow can still circulate freely through the staggered channels, ensuring that the heat dissipation function is not affected. By combining internal channel structure design with absorbent material, the device maintains its original heat dissipation efficiency while enhancing its ability to actively intercept accidental liquid infiltration. The staggered channels increase the difficulty of liquid penetration, and the absorbent components provide secondary protection. The two work together to reduce the risk of liquid contact with internal components, thus ensuring heat dissipation efficiency when the sports watch generates a lot of heat under high load. At the same time, it effectively prevents liquid from seeping into the mounting cavity when the user is sweating or in water, avoiding short circuit failures of electronic components due to liquid contact and extending the service life of the device.

[0022] In existing technologies, sports watches use ventilation holes in the watch body to accelerate heat dissipation for internal components. However, sweat produced by the user's skin during exercise may enter the device through these ventilation holes, causing short circuits and damage to electronic components. Traditional ventilation holes typically employ a straight-through design, allowing liquid to flow directly into the holes, resulting in insufficient protection and making it difficult to balance heat dissipation and waterproofing requirements.

[0023] To solve the above problems, this utility model proposes a sports watch 100. Figure 1 , Figure 2 , Figure 3 as well as Figure 4 A schematic diagram of the structure of an embodiment of the sports watch 100 provided by this utility model.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model proposes a sports watch 100, including a watch body 1 and multiple water-absorbing components 2. The watch body 1 has a mounting cavity 1a for mounting various functional components. The peripheral wall of the mounting cavity 1a has multiple heat dissipation holes 1b. The heat dissipation hole 1b includes a connected inlet 1b1 and an outlet 1b2. The inlet 1b1 is located on the inner peripheral wall of the mounting cavity 1a, and the outlet 1b2 is located on the outer peripheral wall of the mounting cavity 1a. The inlet 1b1 and the outlet 1b2 are staggered. Each water-absorbing component 2 is arranged around the inner peripheral wall of a heat dissipation hole 1b and is close to the inlet 1b1 to absorb liquid entering the mounting cavity 1a from the heat dissipation hole 1b.

[0025] The mounting cavity 1a refers to the enclosed space inside the body 1 used to install electronic components, serving to support and protect the internal components. The heat dissipation hole 1b refers to the airflow channel penetrating the perimeter of the body 1. The staggered arrangement of the inlet 1b1 and outlet 1b2 can be achieved through a segmented bending structure, for example, by using two parallel straight holes connected in a staggered manner, forcing the liquid flow path to deviate. The absorbent component 2 refers to a material component with liquid absorption capacity. Specifically, it can be a block of highly absorbent resin surrounding the inner wall of the heat dissipation hole 1b, which can quickly absorb liquid in the initial stage of entry, preventing it from penetrating into the mounting cavity 1a.

[0026] Specifically, the mounting cavity 1a is assembled with the front shell 11 and the rear cover 12 to form a sealed space, and the heat dissipation hole 1b adopts a non-linear channel to connect the inside and outside. When external liquid enters the heat dissipation hole 1b from the outlet 1b2, since the inlet 1b1 and the outlet 1b2 are misaligned, the liquid needs to change its flow direction to reach the inlet 1b1. The droplets are very likely to collide with the hole wall due to inertia at the turning point, and thus flow along the hole wall. The water-absorbing element 2, which is set near the inlet 1b1 and surrounds the inner peripheral wall of the heat dissipation hole 1b, can absorb the liquid adhering to the hole wall in time. At the same time, the airflow can still circulate freely through the misaligned channel, so that the heat dissipation function is not affected.

[0027] By combining the internal channel structure design with absorbent material, the original heat dissipation efficiency is maintained while the ability to actively intercept accidental liquid infiltration is enhanced. The staggered channels increase the difficulty of liquid penetration, and the absorbent component 2 provides secondary protection. The two work together to reduce the risk of liquid contact with internal components, thus ensuring heat dissipation efficiency when the sports watch 100 generates a lot of heat under high load. At the same time, it effectively prevents liquid from seeping into the installation cavity 1a when the user is sweating or in a wet environment, avoiding short circuit failure of electronic components due to liquid contact and extending the service life of the device.

[0028] Please refer to Figure 3In one embodiment of this utility model, the heat dissipation hole 1b includes a first heat dissipation section 1b3 and a second heat dissipation section 1b4 that are connected to each other; the first heat dissipation section 1b3 is connected to the mounting cavity 1a, and the inlet 1b1 is located at the end of the first heat dissipation section 1b3 away from the second heat dissipation section 1b4; the second heat dissipation section 1b4 is used to connect to the outside, and the outlet 1b2 is located at the end of the second heat dissipation section 1b4 away from the first heat dissipation section 1b3; the water absorption member 2 is connected to the inner wall of the first heat dissipation section 1b3; the first heat dissipation section 1b3 and the second heat dissipation section 1b4 are staggered.

[0029] The first heat dissipation section 1b3 refers to the channel portion directly connected to the mounting cavity 1a, which can be implemented using a cylindrical or prismatic channel structure, with its axial extension direction forming a specific angle with the peripheral wall of the mounting cavity 1a. The second heat dissipation section 1b4 refers to the channel portion connected to the external environment, which can be implemented using a curved or zigzag channel structure, with its axial extension direction spatially misaligned with the first heat dissipation section 1b3. This misalignment means that the axes of the two channel sections are not on the same straight line, which can be achieved through axial offset or angular deflection, forming a non-linear heat dissipation path.

[0030] Specifically, when the heat generated inside the mounting cavity 1a is conducted outward through the first heat dissipation section 1b3, the airflow flows along the axis of the first heat dissipation section 1b3 to the second heat dissipation section 1b4. Due to the misalignment of the axes of the two channels, the airflow forms a turning flow at the connection point, and this turning area creates local resistance. The water-absorbing component 2 is located at the inlet 1b1 end of the first heat dissipation section 1b3 near the mounting cavity 1a. When external liquid enters through the second heat dissipation section 1b4, it needs to pass through the misaligned turning area of ​​the two channels. At this time, the liquid flow path is lengthened and the flow velocity is reduced. Some liquid adheres to the inner wall of the channel in the turning area and is directly absorbed by the water-absorbing component 2. The remaining liquid needs to overcome the turning resistance to continue to penetrate into the mounting cavity 1a.

[0031] By setting up a segmented and staggered heat dissipation hole 1b structure, while ensuring the passage of heat dissipation airflow, the physical barrier formed by the channel bends extends the liquid penetration path, reduces the liquid intrusion speed, and provides the absorbent component 2 with more sufficient adsorption time. Thus, while maintaining heat dissipation efficiency, it effectively improves the protection against sweat intrusion during exercise. The segmented and staggered structure prevents liquid from directly penetrating the channel and forces it to slow down and contact the absorbent component 2 through the bend area, significantly reducing the total amount of liquid entering the mounting cavity 1a and preventing short circuit failures of internal electronic components due to liquid intrusion.

[0032] Please refer to Figure 3 In one embodiment of this utility model, a straight line extending along the central axis of the first heat dissipation section 1b3 is arranged parallel to a straight line extending along the central axis of the second heat dissipation section 1b4.

[0033] Parallel arrangement means that the central axes of the two heat dissipation sections extend in the same direction. This can be achieved by adjusting the bending angle of the channel to prevent liquid from flowing directly into the mounting cavity 1a along a straight path.

[0034] Specifically, the first heat dissipation section 1b3 and the second heat dissipation section 1b4 form a non-linear channel through a staggered structure, but their central axes remain parallel. When external liquid enters through the second heat dissipation section 1b4, due to the parallel and staggered axes of the two channels, the liquid needs to undergo two directional changes before entering the mounting cavity 1a. During the directional change, most of the liquid adheres to the inner wall of the channel due to gravity, with only a small amount potentially continuing to move. Simultaneously, the parallel axis design ensures that the heat dissipation hole 1b maintains an approximately straight orientation, allowing airflow to pass smoothly and heat to be quickly dissipated through air convection.

[0035] By combining parallel axes with a staggered structure, heat dissipation efficiency is maintained, while the difficulty of liquid penetration is increased by changing the direction multiple times. Under the premise of ensuring heat dissipation performance, the non-linear path formed by the parallel axes can effectively block external liquid from entering the mounting cavity 1a, reducing the risk of short circuits caused by liquid contact with internal components, and avoiding heat accumulation caused by excessive bending of the heat dissipation path.

[0036] Please refer to Figure 3 In one embodiment of the present invention, the heat dissipation hole 1b further includes a third heat dissipation segment 1b5, the first and last ends of the third heat dissipation segment 1b5 being connected to the first heat dissipation segment 1b3 and the second heat dissipation segment 1b4 respectively; the angle between the straight line extending along the central axis of the third heat dissipation segment 1b5 and the straight line extending along the central axis of the second heat dissipation segment 1b4 is defined as α, 130°≤α≤140°.

[0037] The third heat dissipation section 1b5 refers to the transition channel between the first heat dissipation section 1b3 and the second heat dissipation section 1b4. Specifically, it can be implemented using a curved channel, with its axis extending at a predetermined angle to the adjacent heat dissipation section. This structure creates a circuitous path by altering the direction of the heat dissipation channel, extending the liquid penetration path while maintaining ventilation. The included angle α refers to the geometric angle between the axes of the third heat dissipation section 1b5 and the second heat dissipation section 1b4. This angle range balances heat dissipation efficiency and liquid blocking effect; if the angle is too small, it will create a sharp bend that obstructs airflow, while if it is too large, it will reduce the blocking effect on the liquid.

[0038] Specifically, when external liquid enters through the second heat dissipation section 1b4, the bending structure of the third heat dissipation section 1b5 forces the liquid flow direction to deflect. Since the included angle α is set between 130 and 140 degrees, the liquid impacts the inner wall of the third heat dissipation section 1b5 under inertia, and some droplets are adsorbed and retained by the pipe wall. At the same time, the airflow can still effectively convect through the continuous heat dissipation path formed by the three-section channel, avoiding a sharp increase in airflow resistance due to excessive bending angles.

[0039] This solution uses a three-section heat dissipation channel combined with a specific angle bend to form a non-linear obstacle in the heat dissipation path. By utilizing the principles of fluid mechanics, droplets collide and linger at the bends, while maintaining the continuity of the airflow channel. This structural innovation achieves synergistic optimization of heat dissipation and waterproof performance without significantly increasing manufacturing difficulty.

[0040] Through the above technical solution, this application effectively solves the contradiction between heat dissipation and liquid intrusion prevention in the sports watch 100 under complex sports scenarios. The bending structure formed by the third heat dissipation section 1b5 not only extends the liquid penetration path, but also maintains heat dissipation efficiency through reasonable angle setting, so that the device can still maintain stable operation in an environment where a lot of sweat is generated during vigorous exercise.

[0041] Please refer to Figure 1 , Figure 2 as well as Figure 3 In one embodiment of the present invention, the body 1 includes a front shell 11 and a rear cover 12. The front shell 11 and the rear cover 12 are detachably connected and enclose to form an installation cavity 1a. Each heat dissipation hole 1b is opened in the front shell 11, and each water absorption component 2 is detachably connected to the rear cover 12.

[0042] The front case 11 refers to the main structure forming the front of the sports watch 100, which can be injection molded from stainless steel or titanium alloy and serves to support the display screen and operation buttons. The back cover 12 refers to the main structure forming the back of the sports watch 100, which can be made of carbon fiber composite material and forms a sealed space with the front case 11. Detachable connection refers to a connection method between the two components that allows for repeated assembly and disassembly through a physical structure, which can be achieved using a snap-fit ​​structure or a threaded fastening structure, facilitating the maintenance of internal functional components. The heat dissipation hole 1b in the front case 11 refers to a through-hole structure penetrating the inner and outer surfaces of the front case 11, which can be formed using laser drilling technology, and serves to establish a heat dissipation channel between the mounting cavity 1a and the outside. The water-absorbing component 2 is detachably connected to the back cover 12, meaning that the water-absorbing component is mechanically fixed to the inside of the back cover 12, which can be a magnetic fixing structure or a slot-type positioning structure, facilitating the periodic replacement of worn-out water-absorbing material.

[0043] Specifically, the front shell 11 and the rear cover 12 are detachably assembled via a snap-fit ​​structure, forming a sealed mounting cavity 1a to accommodate the functional components. The front shell 11 has multiple heat dissipation holes 1b machined on its surface, with the inlet 1b1 located on the inner wall of the mounting cavity 1a and the outlet 1b2 extending to the outer surface of the body 1. Furthermore, since the water-absorbing component 2 and the rear cover 12 are detachably connected, the rear cover 12 can be removed separately for cleaning or replacement during maintenance.

[0044] By designing the heat dissipation vent 1b on the front cover 11 and the water-absorbing component 2 on the back cover 12, the liquid absorption module and the heat dissipation channel are separated. When the water-absorbing component 2 needs to be replaced, only the back cover 12 needs to be removed, avoiding the risk of damage to the display and buttons caused by frequent disassembly and reassembly of the front cover 11. This effectively solves the problem of short circuits in internal components caused by liquid seepage through the heat dissipation vent 1b of the sports watch 100, while also enabling quick maintenance and replacement of the water-absorbing component 2. Because the water-absorbing component 2 and the back cover 12 adopt a modular and detachable design, the complexity of maintenance operations is significantly reduced while ensuring waterproof performance, extending the service life of the sports watch 100 in humid environments.

[0045] Please refer to Figure 2 , Figure 3 as well as Figure 4 In one embodiment of the present invention, the front shell 11 and the rear cover 12 are snapped together; the front shell 11 is provided with a plurality of insertion holes 11a, each insertion hole 11a is connected to a heat dissipation hole 1b, and each water-absorbing component 2 passes through an insertion hole 11a and extends into the corresponding heat dissipation hole 1b.

[0046] The snap-fit ​​connection refers to the mechanical connection between the front shell 11 and the rear cover 12 through a snap-fit ​​structure. Specifically, this can be achieved using a combination of elastic slots and protrusions. This connection method facilitates quick assembly and disassembly without the need for auxiliary tools. The insertion hole 11a is a perforated structure that penetrates the thickness of the front shell 11. Its function is to provide a channel for the absorbent component 2 to pass through the front shell 11 and enter the heat dissipation hole 1b, ensuring that the absorbent component 2 can be accurately positioned in the inlet 1b1 area of ​​the heat dissipation hole 1b. The absorbent component 2 extending into the corresponding heat dissipation hole 1b through the insertion hole 11a refers to a strip-shaped object made of absorbent resin material with a ring-shaped front end being inserted into the heat dissipation hole 1b through the insertion hole 11a. Specifically, this can be achieved using an absorbent rod with a length matching the depth of the heat dissipation hole 1b. This structure allows the absorbent component 2 to directly cover the liquid penetration path at the inlet 1b1 of the heat dissipation hole 1b.

[0047] Specifically, the front shell 11 and the rear cover 12 are assembled using a snap-fit ​​structure, allowing for disassembly without any destructive operations. The insertion holes 11a and heat dissipation holes 1b on the front shell 11 are correspondingly arranged, with the axis of each insertion hole 11a coinciding with the axis of the corresponding heat dissipation hole 1b, ensuring that the absorbent component 2 completely covers the inlet 1b1 area of ​​the heat dissipation hole 1b after insertion. During installation, the absorbent component 2 passes through the insertion hole 11a from the rear cover 12 side, with its end extending to the inner wall of the first heat dissipation section 1b3 of the heat dissipation hole 1b. When liquid enters through the heat dissipation hole 1b, the absorbent component 2 immediately absorbs liquid molecules and forms a barrier layer. During maintenance, the absorbent component 2 can be removed and replaced simply by separating the front shell 11 and the rear cover 12 from the insertion hole 11a.

[0048] The snap-fit ​​structure avoids tool dependence and the risk of structural damage, and enables efficient installation and replacement of liquid barrier components. It also prevents short circuits in internal components caused by sweat seepage. At the same time, the modular design improves the ease of maintenance of the Sports Watch 100 and extends the device's lifespan. Please refer to Figure 2 In one embodiment of this utility model, the water-absorbing component 2 is snapped onto the rear cover 12.

[0049] Specifically, the rear cover 12 and the front shell 11 enclose a mounting cavity 1a, and a heat dissipation hole 1b is opened in the front shell 11, connecting the mounting cavity 1a to the outside. The absorbent component 2 is fixed to the rear cover 12 by a snap-fit ​​structure, such as a slot or protrusion provided on the inner side of the rear cover 12, which engages with the corresponding structure on the absorbent component 2. When the rear cover 12 is separated from the front shell 11, the absorbent component 2 can be directly removed from the snap-fit ​​structure for cleaning or replacement. Since the inlet 1b1 of the heat dissipation hole 1b is located on the inner peripheral wall of the mounting cavity 1a, the absorbent component 2 is positioned close to the inlet 1b1, which can promptly absorb the liquid entering from the heat dissipation hole 1b, and the snap-fit ​​method avoids the disassembly difficulties caused by using adhesives or welding.

[0050] This solution employs a snap-fit ​​structure, allowing the absorbent component 2 to be repeatedly disassembled and reassembled, reducing maintenance costs. Simultaneously, the snap-fit ​​mechanical connection method avoids the risk of fixation failure due to adhesive aging, thus improving reliability.

[0051] Through the above technical solution, this application realizes the convenient replacement and stable fixation of the water-absorbing component 2, which extends the service life of the internal components of the sports watch 100 while ensuring waterproof performance, and is especially suitable for high-intensity sports scenarios that require frequent cleaning or replacement of the water-absorbing component 2.

[0052] Please refer to Figure 2 In one embodiment of the present invention, the sports watch 100 further includes a heat sink 3, which is disposed in the mounting cavity 1a and abuts against the watch body 1; the heat sink 3 is used to install various functional components.

[0053] The heat sink 3 refers to the component used for conducting and dissipating heat, and can be implemented using a structural component made of thermally conductive materials, such as metal or thermally conductive polymer. "Abutting against the body 1" means that the heat sink 3 is in direct contact with the inner wall of the body 1, which can be achieved through fixing or snap-fitting to enhance heat conduction efficiency. "Installing various functional components" refers to integrating various sensors and electrical components onto a circuit board, which is then mounted on the heat sink 3. This can be achieved through screws, clips, or adhesive bonding to simplify the internal structural layout.

[0054] Specifically, the heat sink 3 is disposed inside the mounting cavity 1a and is in close contact with the inner wall of the meter body 1. Functional components are directly mounted on the surface of the heat sink 3, allowing the heat generated during operation to be transferred to the meter body 1 via the heat sink 3, and further dissipated outwards through the surface of the meter body 1 or the heat dissipation holes 1b. Due to the large contact area between the heat sink 3 and the meter body 1, the heat conduction path is shortened, improving heat dissipation efficiency. Simultaneously, the centralized mounting of functional components on the heat sink 3 reduces the complex arrangement of cables and supports within the mounting cavity 1a, lowering the risk of liquid entering through the heat dissipation holes 1b and contacting the components.

[0055] By adding a heat dissipation component 3 that contacts the watch body 1, not only is the installation structure of the internal components optimized, but the internal heat is also quickly conducted to the outer surface of the watch body 1 through direct heat conduction. This avoids the risk of liquid intrusion caused by the increased number of heat dissipation holes 1b, effectively improving the internal heat dissipation efficiency of the sports watch 100 and reducing the performance degradation or damage of components caused by heat accumulation. At the same time, by integrating the installation structure of functional components, the direct impact of liquid intrusion on sensitive components is reduced, extending the service life of the device.

[0056] In one embodiment of this utility model, the heat sink 3 is made of thermally conductive silicone.

[0057] Thermally conductive silicone refers to a composite material made of silicone as the base material and with added thermally conductive fillers. Specifically, aluminum oxide or boron nitride can be used as fillers. It has high thermal conductivity and softness, and can form a tight fit at the contact interface.

[0058] Specifically, a heat sink 3 made of thermally conductive silicone is arranged inside the mounting cavity 1a, maintaining physical contact with the inner wall of the meter body 1. Functional components are directly mounted on the surface of the heat sink 3. The heat generated during operation is transferred to the meter body 1 through the thermally conductive silicone, and then dissipated through heat exchange between the surface of the meter body 1 and the outside air. Because the thermally conductive silicone has elastic deformation capabilities, it can adapt to minor uneven areas on the inner wall of the meter body 1, ensuring a tight, gapless contact surface, thereby reducing thermal resistance.

[0059] In some specific embodiments, the thermally conductive silicone heat sink 3 can be pre-formed into a sheet structure and matched to the mounting position of the functional component through a molding process. During installation, the heat sink 3 is pressed against the inner wall of the body 1, using its own elastic deformation to fill the gaps and form a stable heat conduction path.

[0060] Compared to existing technologies, traditional heat dissipation structures often use metal heat sinks or graphite thermal conductive films. These materials have high hardness, making it difficult to form full contact with the inner wall of the surface within a limited space, resulting in increased local thermal resistance. In contrast, thermally conductive silicone achieves large-area contact through its elastic deformation capability, while avoiding the condensation problems caused by metal materials and reducing the risk of liquid intrusion.

[0061] Through the above technical solution, this application can improve the heat transfer efficiency from the functional components to the watch body 1, and avoid heat accumulation in the mounting cavity 1a, which would lead to a decrease in component performance. At the same time, the hydrophobic properties of the thermally conductive silicone can reduce liquid retention in the heat dissipation path, prevent short circuit problems caused by liquid penetration, and extend the service life of the internal components of the sports watch 100.

[0062] In one embodiment of this utility model, the absorbent element 2 is made of superabsorbent resin.

[0063] The superabsorbent polymer (SAP) refers to a high-molecular polymer material with a three-dimensional network structure, specifically cross-linked polyacrylate. Its molecular chains contain numerous hydrophilic groups, enabling it to rapidly absorb and lock in moisture through hydrogen bonding. In the structure of the sports watch 100, this material actively intercepts liquids. When external liquid enters through the heat dissipation hole 1b, the SAP quickly absorbs the liquid and forms a gel barrier, preventing the liquid from penetrating into the mounting cavity 1a.

[0064] Specifically, a water-absorbing component 2 made of superabsorbent resin is installed on the inner wall of the heat dissipation hole 1b of the body 1. When sweat generated during exercise enters through the heat dissipation hole 1b, the superabsorbent resin captures liquid molecules through the hydrophilic groups of its molecular chains, while the three-dimensional network structure expands to form a physical barrier layer. This process completes the liquid adsorption near the inlet 1b1 of the heat dissipation hole 1b, which maintains the airflow exchange function of the heat dissipation channel and prevents liquid from contacting the internal electronic components.

[0065] Compared to existing technologies, traditional sports watches using ordinary absorbent materials suffer from low liquid absorption capacity and poor water retention, allowing liquids to easily penetrate the absorbent layer and enter the device. In contrast, superabsorbent polymers (SAPs) have monomer molecular weights in the millions, resulting in water absorption capacity dozens of times greater than ordinary materials. Furthermore, their gel structure effectively prevents liquid backflow, significantly improving waterproof reliability.

[0066] Through the above technical solution, this application solves the hidden danger of short circuit of internal components caused by liquid seepage into the heat dissipation hole 1b of the sports watch 100. By forming a dual protection mechanism through the directional adsorption of super absorbent resin, the service life of electronic components is extended while maintaining heat dissipation efficiency.

[0067] 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.
