Description

Technical Field

[0001] This utility model relates to the technical field of waterproof structures for watches, specifically a waterproof structure for smartwatches. Background Technology

[0002] Currently, there are many types of smartwatches on the market. For example, smartwatches that can monitor heart rate and blood oxygen saturation essentially use an LED light source and a photoelectric sensor to receive reflected light, installed inside the smartwatch near the back cover. This requires an opening in the back cover, and a waterproof and breathable membrane needs to be glued inside the opening to ensure waterproof sealing and air pressure balance. Although the waterproof and breathable membrane can achieve the effect of waterproofing and breathability, it is generally fixed to the back cover with adhesive, lacking a reinforced sealing structure. After long-term use, the adhesion between the adhesive layer and the membrane or metal back cover is easily damaged by sweat corrosion, moisture, chemical intrusion, or high-pressure water impact. This can cause the adhesive between the waterproof and breathable membrane and the back cover to detach, allowing moisture or liquid to enter through the detached gaps and corrode the internal electronic components.

[0003] The purpose of this invention is to provide a waterproof structure for smartwatches to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a watch body and a monitoring channel opened at the bottom of the watch body cover, wherein a waterproof and breathable membrane is bonded to the inside of the monitoring channel.

[0005] The watch body has a mounting groove at the bottom of the cover plate. A pressure plate is provided inside the mounting groove. Sealing grooves are provided inside the mounting groove and on the top of the pressure plate. A sealing gasket is snapped between the two sealing grooves. A fixing groove is provided on the top of the pressure plate. A sealing pressure ring that works with the waterproof and breathable membrane frame is provided inside the fixing groove.

[0006] In a further embodiment, the pressure plate and the bottom cover of the watch body are detachably threaded together by bolts.

[0007] In a further embodiment, the top of the pressure plate is integrally injection molded with a sealing edge wall, and a sealing ring is fitted onto the surface of the sealing edge wall.

[0008] In a further embodiment, the mounting groove has an inner groove that mates with the sealing ring.

[0009] In a further embodiment, a circular through groove is provided at the bottom of the pressure plate, and the size of the circular through groove is consistent with the size of the waterproof and breathable part of the waterproof and breathable membrane.

[0010] In a further embodiment, the watch body is symmetrically fitted with watch strap mounting brackets.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention features an installation groove at the bottom of the watch body, with a pressure plate installed inside. In conjunction with a sealing gasket and a sealing pressure ring, a secondary seal can be created between the pressure plate and the waterproof and breathable membrane. This prevents external moisture or sweat from entering the sealing layer between the waterproof and breathable membrane and the bottom cover, thus preventing the adhesive layer from peeling off and ensuring a waterproof seal.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This embodiment discloses a waterproof structure for a smartwatch, including a watch body 1 and a monitoring channel 2 formed at the bottom of the cover of the watch body 1. A waterproof and breathable membrane 3 is adhered to the inside of the monitoring channel 2. A watch strap mounting base 14 is symmetrically mounted on the surface of the watch body 1. Figure 1 and Figure 2As shown in this application, the watch body 1 is an existing smartwatch with heart rate monitoring function, specifically the Huawei Watch GT 3 Pro smartwatch. Its basic functions and structure can be referenced from the Watch GT 3 Pro smartwatch. The waterproof and breathable membrane 3 is installed at the opening of the bottom cover of the watch body 1 for waterproof and dustproof, pressure balancing and sound transmission functions. The watch strap mounting base 14 is symmetrically designed on the surface of the watch body 1 for installing the watch strap for the user's convenience.

Sealing grooves 6 are formed both inside the mounting groove 4 and on the top of the pressure plate 5. A sealing gasket 7 is engaged between the two sealing grooves 6. A fixing groove 8 is formed on the top of the pressure plate 5. A sealing pressure ring 9, which mates with the frame of the waterproof and breathable membrane 3, is installed inside the fixing groove 8. Figure 1 , Figure 2 and Figure 3 As shown, the mounting groove 4 is formed on the bottom cover of the watch body 1 for mounting the pressure plate 5. The pressure plate 5 is located inside the mounting groove 4, and preferably, the pressure plate 5 is bolted to the bottom cover of the watch body 1. The sealing ring 11 is designed inside the sealing groove 6 on the bottom cover of the watch body 1 and the pressure plate 5. When the pressure plate 5 is inserted into the mounting groove 4, the sealing ring 11 can seal the space between the pressure plate 5 and the bottom cover of the watch body 1, preventing external moisture from entering the waterproof and breathable membrane 3 and the wrist through the gap between the bottom cover of the watch body 1 and the pressure plate 5. At the adhesive layer between the bottom cover and the main body 1 of the watch, a fixing groove 8 is opened on the top of the pressure plate 5, and a sealing ring 9 is installed inside the fixing groove 8. When the pressure plate 5 is installed inside the mounting groove 4, the sealing ring 9 inside the fixing groove 8 contacts the waterproof and breathable membrane 3, preventing external moisture from entering the adhesive layer between the waterproof and breathable membrane 3 and the bottom cover of the watch body 1 through the gap between the pressure plate 5 and the waterproof and breathable membrane 3, thus achieving the purpose of secondary sealing.
