[0025] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0026] Please refer to Figures 1 to 9 The present application provides a technical solution.

[0027] The triple waterproof sealing structure of the smart watch comprises a watch case 1 and a back cover 11, the inner side of the back cover 11 is movably connected with a pressure disc assembly, a sealing ring 12 is arranged between the pressure disc assembly and the watch case 1, a glue injection groove 2 is formed in the top of the watch case 1, the glue injection groove 2 is filled with sealing glue, the watch case 1 and the back cover 11 are detachably connected, and the specific connection mode can adopt the mature technology commonly used in existing watches, such as threaded connection, buckle connection, etc., the surface of the back cover 11 is threadedly connected with an adjusting knob 9, the adjusting knob 9 is rotatably connected with the pressure disc assembly, and the adjusting knob 9 is used for adjusting the compression degree of the pressure disc assembly to the sealing ring 12.

[0028] The pressure disc assembly comprises a disc 6 and a pressing ring 5, the pressing ring 5 is fixedly connected to the bottom end of the disc 6, the bottom end of the pressing ring 5 and the top end of the watch case 1 are symmetrically provided with a sealing groove 3 for embedding the sealing ring 12, when the sealing ring 12 is installed, the sealing ring 12 is first placed into the sealing groove 3 at the top end of the watch case 1, then the sealing glue is filled into the glue injection groove 2, then the back cover 11 is installed on the watch case 1, at this time, the sealing ring 12 is synchronously embedded into the sealing groove 3 at the bottom end of the pressing ring 5, then the adjusting knob 9 is rotated, because the adjusting knob 9 is threadedly matched with the back cover 11, the adjusting knob 9 moves axially and synchronously drives the pressure disc assembly to move, so that the pressing ring 5 approaches or moves away from the watch case 1, thereby accurately adjusting the compression degree of the sealing ring 12.

[0029] The top end of the watch case 1 is provided with a let -by slot 4, which is used to provide space for the movement of the compression ring 5. Through the threaded transmission of the adjusting knob 9 and the compression disc assembly, the manual rotating force is converted into the uniform axial pressure of the compression ring 5 on the sealing ring 12. When the adjusting knob 9 is rotated, the compression ring 5 moves vertically along the let -by slot 4, avoiding damage to the sealing ring 12 caused by manual pressing or uneven installation. The depth and width of the sealing ring 12 and the sealing groove 3 need to be strictly matched, such as the interference amount tolerance ± 0.02mm, otherwise it is easy to cause installation not in place or stress concentration. The compression amount of the sealing ring 12 is dynamically adjusted by the adjusting knob 9, so that the compression rate of the sealing ring 12 is kept in a reasonable range, such as 20% ~ 30%, instead of relying on the initial machining precision and manual meticulous assembly. According to the need, the surface of the adjusting knob 9 can be marked with a rotating scale to facilitate the observation of the rotating angle. The compression force of the sealing ring 12 is dynamically adjusted through the mechanical linkage of the adjusting knob 9 and the compression disc assembly. These improvements can keep the sealing ring 12 stable compression rate in a wide temperature environment. The compression force of the sealing ring 12 can be adjusted according to the environmental temperature, avoiding the sealing failure or material aging acceleration caused by thermal expansion and cold shrinkage.

[0030] The top end of the disc 6 is fixedly connected with a T-shaped shaft 7. The bottom end of the adjusting knob 9 is provided with a T-shaped circular groove 8 for the rotation of the T-shaped shaft 7. Through such connection, the rotation of the adjusting knob 9 is facilitated, and the compression disc assembly can be driven to move axially.

[0031] The surface of the adjusting knob 9 is provided with a force groove 10. Through such setting, it is convenient to cock the adjusting knob 9 to rotate.

[0032] The surface of the disc 6 is provided with a charging interface. The surface of the rear cover 11 is provided with a through hole aligned with the charging interface. The surface of the rear cover 11 is provided with a sealing plug 13 matched with the through hole. The sealing plug 13 and the through hole can be connected through plug connection. The rotating sealing ring 14 is tightly sleeved outside the charging interface. The outer side of the rotating sealing ring 14 and the inner wall of the charging interface are in interference fit. Anti -skid texture is arranged on the surface of the rotating sealing ring 14, which is convenient for users to rotate the rotating sealing ring 14 to open and close the charging interface.

[0033] The rotating sealing ring 14 adopts fluorine rubber as the material. Fluorine rubber has excellent chemical corrosion resistance, can resist the corrosion of water, seawater, sweat and other liquids, and has good high temperature resistance and aging resistance, which can ensure that the rotating sealing ring 14 maintains stable sealing effect in the process of long -term use. In addition, the elasticity and wear resistance of fluorine rubber are good, which can adapt to the frequent rotating operation of the charging interface, so as to expose or block the charging interface, reduce wear and tear, and prolong the service life of the sealing ring.

[0034] The internal and external surfaces of the charging interface are evenly coated with a nano-hydrophobic film, including the charging contacts, the inner wall of the interface, etc. In the open state of the charging interface, the nano-hydrophobic film can prevent water from entering the interface interior, and in the closed state, it cooperates with the rotating sealing ring 14 to form a double-sealing barrier, further improving the waterproof performance.

[0035] The nano-hydrophobic film is a thin film with super-hydrophobic properties. It is made of nanoscale materials and has good air and light permeability, which does not affect the signal transmission and charging function of the charging interface. At the same time, the nano-hydrophobic film has excellent wear resistance and chemical corrosion resistance, which can effectively prevent water, dust and other pollutants from adhering to the surface of the charging interface.

[0036] The side of the watch case 1 is equipped with an air pressure balance valve 15, the inside of which is covered with a waterproof and air-permeable film, which allows air to pass through while preventing water from entering.

[0037] The main function of the air pressure balance valve 15 is to balance the air pressure inside and outside the watch, preventing the sealing structure from failing due to excessive internal and external air pressure differences in deep water environments. When the watch enters the water, the external water pressure increases as the water depth increases. By opening the air pressure balance valve 15, the air inside the watch is released, keeping the internal and external air pressure balanced. When operating the watch in wet water, the watch uses advanced capacitive screen calibration algorithms to detect the thickness and distribution of the water film on the touch screen surface in real time, adjust the sensitivity and threshold of the touch signal, and ensure the accuracy of touch operation. When the watch detects that it is in a wet water environment, the built-in humidity sensor and acceleration sensor automatically trigger the wet water mode.

[0038] The specific scheme is: the sealing ring 12 is clamped with a forceps, is slowly put into the sealing groove 3 at the top end of the watch case 1 in alignment, ensures that the sealing ring 12 is completely without distortion, folding phenomenon, and checks its fit with the sealing groove 3, then slowly injects the sealing glue along the glue injection groove 2 at the top of the watch case 1, makes it evenly fill the glue injection groove 2, attention is avoided to overflow, the filling amount is slightly higher than the surface of the glue injection groove 2, so that the sealing glue can effectively seal the joint surface when the back cover 11 is installed subsequently, then the pressure disc assembly inside the back cover 11 is aligned with the top end of the watch case 1, the sealing groove 3 at the bottom end of the pressure ring 5 is aligned with the sealing groove 3 at the top end of the watch case 1, the back cover 11 is slowly put down, and the sealing ring 12 is synchronously embedded in the sealing groove 3 at the bottom end of the pressure ring 5, the process is kept horizontal, prevents the sealing ring 12 from being displaced, then is fixed according to the connection mode of the watch case 1 and the back cover 11, then according to the compression rate requirement of the sealing ring 12, the adjusting knob 9 is rotated, the pressure disc assembly is axially moved, the pressure ring 5 is vertically downward along the accommodation groove 4 at the top end of the watch case 1, the sealing ring 12 is uniformly axially pressed, and then the compression amount of the sealing ring 12 is adjusted, and the environmental adaptability is adjusted, when used in different temperature environments, according to the thermal expansion and cold shrinkage principle, the compression force of the sealing ring 12 is dynamically adjusted through the adjusting knob 9, in a low-temperature environment, the sealing ring 12 shrinks, at this time, the adjusting knob 9 is rotated to increase the compression force, so that the reasonable compression rate of the sealing ring 12 is ensured, in a high-temperature environment, the sealing ring 12 expands, and then the adjusting knob 9 is reversely rotated to reduce the compression force, so that the material aging is prevented due to excessive stress.

[0039] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
