[0002] Smartwatches are innovative products that combine traditional watch functions with smart technology. By integrating various advanced technologies, they enable users to more conveniently manage time, monitor health, receive notifications, and more, making them popular with many users. With the rapid development of smartwatch technology, waterproof performance has become a key consideration in product design. Advances in microelectronics have led to the miniaturization and efficiency of core components, including sensors and chips, as well as breakthroughs in waterproof sealing technology. In recent years, smartwatches have achieved waterproof performance that is generally resistant to sweat and light splashes, such as hand washing, showering, and short swimming pool immersion. During production, existing smartwatches add uncured sealant to the contact surface between the cover and the housing. The cover is then pressed to evenly adhere the sealant to the contact surface. Pressing the cover squeezes excess sealant out of the contact surface, requiring cleaning after the sealant cures. This increases production steps and reduces efficiency. Therefore, a waterproof structure for a smartwatch, a smartwatch, and a smart wearable device are proposed. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0032] Reference Figures 1 to 6 An embodiment of the present invention provides a smart wearable device, which includes a smart watch, and the smart watch includes a waterproof structure of the smart watch, and the waterproof structure of the smart watch includes a watch case 10 and a face cover 20. The cross-section of the watch case 10 is circular, and the watch case 10 has a wearing surface and an observation surface. When the smart watch is worn on the hand, the surface in contact with the hand is the wearing surface, and the surface for the user to observe is the observation surface. The observation shell surface opening of the watch case 10 forms an inner cavity, and an electronic component 40 is arranged in the inner cavity. The face cover 20 covers the opening of the watch case 10 so that the inner cavity forms a sealed inner cavity, thereby achieving the waterproof performance of the smart watch.

[0033] The cover 20 is bonded to the watch case 10 using sealant. Specifically, the cover 20 includes an outer frame 22 connected to the watch case 10. The upper surface of the watch case 10 has a glue-dispensing area 11 surrounding the inner cavity of the watch case 10. The outer frame 22 has a glue-sealing area 23 corresponding to the glue-dispensing area 11. During assembly, uncured sealant is evenly applied to the glue-dispensing area 11. The glue-sealing area 23 is then aligned with the glue-dispensing area 11 and the cover 20 and watch case 10 are pressed together. Once the sealant cures, the cover 20 and watch case 10 are bonded.

[0034] Furthermore, to prevent the sealant from being squeezed outside the sealed space formed by the glue-dispensing area 11 and the glue-sealing area 23 when the cover 20 and the watch case 10 are pressed together, in this embodiment, a first protrusion 12 is provided on the outside of the glue-dispensing area 11, and a second protrusion 13 is provided on the inside of the glue-dispensing area 11. Specifically, the glue-dispensing area 11 is the area enclosed by the first and second protrusions 12, 13. Furthermore, to improve the positioning accuracy of the cover 20 when it is placed on the watch case 10, a second groove 24 is provided in the glue-sealing area 23, corresponding to the second protrusion 13. During the closing operation, the second groove 24 is aligned with the second protrusion 13 so that the second protrusion 13 engages with the second groove 24. When the cover 20 and the watch case 10 are pressed together, the first protrusion 12 effectively prevents the sealant from flowing toward the outside of the watch case 10, while the second protrusion 13 effectively prevents the sealant from flowing toward the inside of the watch case 10 (i.e., the inner cavity of the watch case 10).

[0035] Furthermore, a first groove 14 is provided at one end of the glue-dispensing area 11 near the first protrusion 12. During the extrusion of the cover 20, the distance between the glue-dispensing area 11 and the sealing area 23 decreases, the sealant is evenly bonded between the glue-dispensing area 11 and the sealing area 23, and the space for the sealant gradually decreases. At this point, excess sealant flows into the first groove 14, effectively preventing the sealant from overflowing from the gap.

[0036] It should be noted that the face cover 20 further includes a transparent cover plate 21. The cross section of the watch case 10 is circular, and accordingly, the outer frame 22 is annular. The transparent cover plate 21 is disposed on the center hole of the outer frame 22 and is fixedly connected to the outer frame 22.

[0037] Furthermore, the height of the second protrusion 13 is greater than the depth of the second groove 24. After pressing the face cover 20 and the watch case 10, it is necessary to make a certain distance between the glue dispensing area 11 and the glue sealing area 23, and the distance is the thickness of the sealant after curing. Generally speaking, the waterproof performance of a sealant that is too thin is low. In this embodiment, by controlling the difference between the height of the second protrusion 13 and the depth of the second groove 24, the thickness of the sealant is controlled, thereby avoiding excessive squeezing of the face cover 20 to cause the sealant to be too thin and affect the waterproof performance. Optionally, the difference between the height of the second protrusion 13 and the depth of the second groove 24 is between 0.3mm and 1.0mm, that is, the thickness of the sealant after curing is between 0.3mm and 1.0mm.

[0038] Optionally, a protrusion 25 is provided on the outer side surface of the outer frame 22 to abut against the upper surface of the first protrusion 12, so as to further prevent the cover 20 from being over-extruded and causing the sealant to be too thin.

[0039] Furthermore, the face cover 20 is also connected to the watch case 10 by bolts. Specifically, a fixing ear 30 is provided on the outer wall of the watch case 10, and a threaded hole 31 is provided on the fixing ear 30; a connecting ear 32 is provided on the outer wall of the outer frame 22, and a connecting hole 33 corresponding to the threaded hole 31 is provided on the connecting ear 32. If the watch case 10 and the face cover 20 are only bonded by sealant, the face cover 20 will easily fall off the watch case 10 during long-term use. Therefore, when uncured sealant is applied to the glue dot area 11 and the face cover 20 is covered on the watch case 10, a bolt is passed through the connecting hole 33 and gradually tightened. The process of tightening the bolt is the process of pressing the face cover 20 and the watch case 10 together.

[0040] Furthermore, the fixing lug 30 is provided with a third groove 34, and the threaded hole 31 is provided on the bottom wall of the third groove 34. The bottom wall of the third groove 34 is connected to the glue-dispensing area 11, and the side of the connecting lug 32 near the fixing lug 30 is connected to the glue-sealing area 23. In other words, the bottom wall of the third groove 34 forms a portion of the glue-dispensing area 11, and the bottom surface of the connecting lug 32 forms a portion of the glue-sealing area 23. The thickness of the third groove 34 is equal to that of the connecting lug 32. When the cover 20 is bolted to the watch case 10, the connecting lug 32 is embedded in the third groove 34, effectively enhancing the aesthetics of the smartwatch.

[0041] Furthermore, a plurality of knobs 50 are provided on one side of the watch case 10, and the knobs 50 are rotatably connected to the watch case 10 via a rotating shaft 51. A through hole 15 is provided on the side wall of the watch case 10, and the rotating shaft 51 passes through the through hole 15 and is connected to the electronic component 40. The knobs 50 are used for various operations such as selecting, adjusting and setting the navigation interface of the smart watch, controlling time and date, adjusting volume, and quickly switching applications. In order to prevent water from entering the inner cavity of the watch case 10 through the through hole 15, a double sealing ring 52 is provided on the inner wall of the through hole 15. The double sealing ring 52 is compressed between the outer peripheral surface of the rotating shaft 51 and the inner wall of the through hole 15, effectively preventing external water from entering the inner cavity of the watch case 10 from the through hole 15.

[0042] The waterproof structure of a smartwatch disclosed in the present invention is specifically implemented as follows: during production of the smartwatch, uncured sealant is first evenly applied to the glue-dispensing area 11 of the watch case 10, and then the cover 20 is placed over the opening of the watch case 10. During the closing process, the second groove 24 is aligned with the second protrusion 13 to achieve precise positioning during closing. When the cover 20 is squeezed, the first protrusion 12 prevents excess sealant from overflowing toward the outside of the watch case 10, and the second protrusion 13 prevents excess sealant from flowing into the interior of the watch case 10. During the squeezing process of the cover 20, the distance between the glue-dispensing area 11 and the glue-sealing area 23 continuously decreases, and the sealant is evenly bonded between the glue-dispensing area 11 and the glue-sealing area 23, with excess sealant flowing toward the first groove 14. The utility model effectively prevents the sealant from flowing out of the sealing area when the surface cover 20 is squeezed by providing the first protrusion 12 and the second protrusion 13. The utility model provides a storage space for excess sealant by providing the first groove 14, thereby avoiding the excess sealant from overflowing. The overflowed sealant can be cleaned after the sealant is cured, thereby reducing the production process and improving the production efficiency.

[0043] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
