Description

Technical Field

[0001] This invention belongs to the field of smart wearable device technology, specifically, it relates to a smart watch with a finger electrode insulation and waterproof structure. Background Technology

[0002] With the development of mobile and internet technologies, smart wearable devices have gradually entered people's lives. By connecting with smartphones, home networks, or the internet, people can conveniently obtain practical information such as time, temperature, emails, or phone calls. It is precisely because of the multifunctionality and portability of smart wearable devices that they greatly facilitate people's daily lives, and therefore, smart wearable devices are becoming increasingly popular.

[0003] Considering the requirements for durability and aesthetic design, some wearable devices, especially smartwatches, are typically made of metal. However, metal can shield wireless signals, leading to interruptions in wireless communication between smart wearable devices and external devices, or short wireless signal transmission distances. The traditional solution is to design the signal feed point of the FPC (flexible printed circuit board) inside the smartwatch casing to the outside of the casing to solve the signal transmission problem. However, this leads to new problems, such as the need to drill holes in the casing, which compromises the casing's integrity. When the antenna feed comes into contact with the metal casing, communication signal interruptions or instability may still occur, and the overall waterproof performance of the casing is also reduced. Therefore, the insulation and waterproof performance of smartwatches needs further improvement. In view of this, the present invention is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a smart watch with a finger electrode insulated and waterproof structure that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a smartwatch with an insulated and waterproof finger electrode structure, comprising a watch body, a main control chip, a flexible circuit board, a metal finger electrode, and a locking screw. The main control chip is installed in the watch body, the flexible circuit board is installed in the watch body and electrically connected to the main control chip, the metal finger electrode is installed in a mounting opening on the side of the watch body and is fixed tightly to the flexible circuit board by the locking screw, and further comprising: a waterproof insulating sleeve, which is sleeved on the outside of the metal finger electrode; the metal finger electrode is installed on the watch body through the waterproof insulating sleeve. The mounting opening is located on the side of the main body; a threaded hole is provided inside the metal finger electrode, and the locking screw is threaded into the threaded hole; a cavity communicating with the threaded hole is provided on the side of the metal finger electrode near the threaded hole; an air supply bladder is installed in the cavity; an annular air bladder is installed in a groove provided on the outer side of the metal finger electrode; the air supply bladder and the annular air bladder are connected by a connecting pipe; wherein, when the locking screw is turned into the threaded hole, the air supply bladder will be compressed, and then the gas in the air supply bladder will enter the annular air bladder through the connecting pipe, causing the annular air bladder to inflate and fit tightly against the waterproof insulating sleeve.

[0006] To facilitate the tightening of the screws to compress the air supply bag, a push plate is further included. The push plate is positioned inside the threaded hole near the cavity. A compression plate is provided on the side of the cavity near the push plate. The compression plate is in contact with the air supply bag. The push plate and the compression plate are connected by a connecting rod. A telescopic spring is fixedly connected between the push plate and the inner wall of the threaded hole.

[0007] To facilitate the rapid return of the air supply bladder when the extrusion plate retracts, thereby allowing the annular air bladder to fully return to its original position and facilitating better separation of the metal finger electrode from the waterproof insulating sleeve, multiple return springs are fixedly connected at equal intervals inside the air supply bladder.

[0008] To facilitate the limiting function of the push plate and prevent it from rotating with the locking screw, thus avoiding wear on the air supply bag caused by the squeezing plate, further, the metal finger electrode has symmetrical limiting grooves on both sides of the threaded hole. A first T-shaped slider is slidably connected in the limiting groove, and the first T-shaped slider is fixedly connected to the push plate.

[0009] To further protect the push plate and prevent the locking screw from damaging it, an annular limiting groove is provided on the side of the push plate near the locking screw. A protective plate is provided on the side of the push plate near the locking screw, and a second T-shaped slider is symmetrically fixedly connected to the side of the protective plate near the push plate. The second T-shaped slider is slidably connected in the annular limiting groove.

[0010] To facilitate a more secure assembly between the metal finger electrode and the waterproof insulating sleeve, prevent separation between the metal finger electrode and the waterproof insulating sleeve, and also prevent the assembly of the metal finger electrode and the waterproof insulating sleeve from falling out of the mounting opening of the watch body, a first protrusion and a second protrusion are respectively provided at the ends of the metal finger electrode and the waterproof insulating sleeve near the flexible circuit board.

[0011] To facilitate sealing the gap between the inner wall of the installation port and the waterproof insulating sleeve and improve the waterproof effect, the waterproof insulating sleeve is further provided with waterproof ribs, and waterproof rubber rings are fitted onto the waterproof ribs of the waterproof insulating sleeve.

[0012] To ensure a tighter fit between the waterproof insulating sleeve and the inner wall of the watch body's mounting opening and the metal finger electrodes when compressed, the waterproof insulating sleeve is further made of silicone.

[0013] To facilitate better contact between the flexible circuit board and the metal finger electrode, a wave-shaped washer is further installed between the flexible circuit board and the metal finger electrode via a locking screw.

[0014] To facilitate the positioning of the waveform pad and prevent it from shifting and affecting its installation, a positioning groove is further provided on the side of the flexible circuit board near the metal finger electrode, and the waveform pad is positioned within the positioning groove of the flexible circuit board.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: By setting the locking screw and waterproof insulating sleeve, the present invention can achieve waterproof and insulating effects on the metal finger electrode during installation, improving the safety of the smartwatch during use. At the same time, through the combined use of push plate, telescopic spring, connecting rod, squeezing plate, air supply airbag, annular airbag, etc., the metal finger electrode can be further sealed. This not only further improves the waterproof effect of the waterproof insulating sleeve on the metal finger electrode, but also makes the connection between the metal finger electrode and the waterproof insulating sleeve tighter, preventing the metal finger electrode from separating from the waterproof insulating sleeve, effectively ensuring the insulation and waterproof effect of the metal finger electrode. Moreover, the structure is simple, easy to assemble and disassemble, and has a low cost.

[0016] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] Example 1:

[0034] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 10A smartwatch with an insulated and waterproof finger electrode structure includes a watch body 1, a main control chip 101, a flexible circuit board 2, metal finger electrodes 3, and a locking screw 5. The main control chip 101 is installed inside the watch body 1, the flexible circuit board 2 is installed inside the watch body 1 and electrically connected to the main control chip 101, and the metal finger electrode 3 is installed in a mounting opening on the side of the watch body 1 and is fixed tightly to the flexible circuit board 2 by the locking screw 5. The watch also includes a waterproof insulating sleeve 4, which is fitted over the outside of the metal finger electrode 3; the metal finger electrode 3 is installed in the mounting opening on the side of the watch body 1 through the waterproof insulating sleeve 4; and the metal finger electrode 3 has threads inside. Hole 302, locking screw 5 is threaded into threaded hole 302; metal finger electrode 3 has a cavity 303 that communicates with threaded hole 302 on the side near threaded hole 302; air supply bag 304 is installed in cavity 303; annular air bag 306 is installed in a groove on the outside of metal finger electrode 3; air supply bag 304 and annular air bag 306 are connected by a connecting pipe; wherein, when locking screw 5 is turned into threaded hole 302, air supply bag 304 will be compressed, and then the gas in air supply bag 304 will enter annular air bag 306 through connecting pipe, causing annular air bag 306 to inflate and fit tightly against waterproof insulating sleeve 4;

[0035] Reference Figure 7 , Figure 8 It also includes a push plate 309, which is located in the threaded hole 302 near the cavity 303. A squeeze plate 307 is provided in the cavity 303 near the push plate 309. The squeeze plate 307 is in contact with the air supply bag 304. The push plate 309 and the squeeze plate 307 are connected by a connecting rod 3010. A telescopic spring 308 is fixedly connected between the push plate 309 and the inner wall of the threaded hole 302.

[0036] When assembling the smartwatch, after installing the main control chip 101, battery, and other components, the metal finger electrode 3 needs to be installed. First, the metal finger electrode 3 is installed inside the waterproof insulating sleeve 4. Then, the waterproof insulating sleeve 4 with the metal finger electrode 3 installed is installed into the mounting opening on the side of the watch body 1. Next, one end of the flexible circuit board 2 is connected to the main control chip 101, and the signal receiving end of the flexible circuit board 2 is placed against the metal finger electrode 3. Then, the flexible circuit board 2 and the metal finger electrode 3 are installed using the locking screw 5. As the locking screw 5 rotates continuously in the threaded hole 302 inside the metal finger electrode 3, the metal finger electrode 3 will be tightly fitted against the waterproof insulating sleeve 4 under the action of the locking screw 5. The waterproof insulating sleeve 4 will then be tightly fitted against the inner wall of the mounting opening of the watch body 1, and the metal finger electrode 3 will be tightly fitted against the flexible circuit board 2. As the locking screw 5 continues to move into the threaded hole 302, when it contacts the push plate 309, it will push the push plate 309 against the extension spring. The elastic force of 308 moves towards the side closer to cavity 303, and then push plate 309 drives extrusion plate 307 to extrude air supply bag 304 through connecting rod 3010. Then the gas in air supply bag 304 is transported to annular bag 306 through connecting pipe. As the gas in annular bag 306 increases, annular bag 306 will expand and then tightly adhere to the inner wall of waterproof insulating sleeve 4. At the same time, the position of waterproof insulating sleeve 4 adjacent to annular bag 306 will also be concave under the pushing of annular bag 306. Then annular bag 306 will be locked in the concave part of waterproof insulating sleeve 4. This not only further improves the waterproof effect of waterproof insulating sleeve 4 on metal finger electrode 3, but also makes the connection between metal finger electrode 3 and waterproof insulating sleeve 4 tighter, preventing metal finger electrode 3 from separating from waterproof insulating sleeve 4. This effectively ensures the insulation and waterproof effect of metal finger electrode 3. Moreover, the structure is simple, easy to assemble and disassemble, and has low cost.

[0037] Example 2:

[0038] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 10A smartwatch with an insulated and waterproof finger electrode structure includes a watch body 1, a main control chip 101, a flexible circuit board 2, metal finger electrodes 3, and a locking screw 5. The main control chip 101 is installed inside the watch body 1, the flexible circuit board 2 is installed inside the watch body 1 and electrically connected to the main control chip 101, and the metal finger electrode 3 is installed in a mounting opening on the side of the watch body 1 and is fixed tightly to the flexible circuit board 2 by the locking screw 5. The watch also includes a waterproof insulating sleeve 4, which is fitted over the outside of the metal finger electrode 3; the metal finger electrode 3 is installed in the mounting opening on the side of the watch body 1 through the waterproof insulating sleeve 4; and the metal finger electrode 3 has threads inside. Hole 302, locking screw 5 is threaded into threaded hole 302; metal finger electrode 3 has a cavity 303 that communicates with threaded hole 302 on the side near threaded hole 302; air supply bag 304 is installed in cavity 303; annular air bag 306 is installed in a groove on the outside of metal finger electrode 3; air supply bag 304 and annular air bag 306 are connected by a connecting pipe; wherein, when locking screw 5 is turned into threaded hole 302, air supply bag 304 will be compressed, and then the gas in air supply bag 304 will enter annular air bag 306 through connecting pipe, causing annular air bag 306 to inflate and fit tightly against waterproof insulating sleeve 4;

[0039] Reference Figure 7 , Figure 8 It also includes a push plate 309, which is located in the threaded hole 302 near the cavity 303. A squeeze plate 307 is provided in the cavity 303 near the push plate 309. The squeeze plate 307 is in contact with the air supply bag 304. The push plate 309 and the squeeze plate 307 are connected by a connecting rod 3010. A telescopic spring 308 is fixedly connected between the push plate 309 and the inner wall of the threaded hole 302.

[0040] Reference Figure 7 Furthermore, multiple return springs 305 are fixedly connected at equal intervals inside the air supply bladder 304. By installing multiple return springs 305 inside the air supply bladder 304, when the compression plate 307 retracts, the air supply bladder 304 can quickly return to its original position, thereby facilitating the return of the annular air bladder 306 to the air supply bladder 304, and thus facilitating the better separation of the metal finger electrode 3 from the waterproof insulating sleeve 4.

[0041] Reference Figure 8Furthermore, the metal finger electrode 3 has symmetrically provided limiting grooves 3011 on both sides of the threaded hole 302. A first T-shaped slider 3012 is slidably connected in the limiting groove 3011. The first T-shaped slider 3012 is fixedly connected to the push plate 309. Through the cooperation of the limiting groove 3011, the first T-shaped slider 3012 and the push plate 309, the push plate 309 can be limited so that when the locking screw 5 contacts the push plate 309, the push plate 309 can be prevented from rotating with the locking screw 5. The push plate 309 can only move back and forth, thereby preventing the extrusion plate 307 from causing wear to the air supply bag 304 and effectively improving the protection effect of the air supply bag 304.

[0042] Reference Figure 8 It should be noted that an annular limiting groove is provided on the side of the push plate 309 near the locking screw 5, and a protective plate 3013 is provided on the side of the push plate 309 near the locking screw 5. A second T-shaped slider 3014 is symmetrically fixedly connected to the side of the protective plate 3013 near the push plate 309. The second T-shaped slider 3014 is slidably connected in the annular limiting groove. With the setting of the protective plate 3013 and the second T-shaped slider 3014, when the locking screw 5 rotates into the threaded hole 302 and pushes the push plate 309 to move, the locking screw 5 will drive the protective plate 3013 to rotate together, thereby protecting the push plate 309 and preventing the locking screw 5 from damaging the push plate 309, effectively improving the protection effect of the push plate 309.

[0043] Example 3:

[0044] Reference Figures 11-12 A smartwatch with a finger electrode insulated and waterproof structure is basically the same as in Embodiment 2. However, a further improvement is achieved by providing a first protrusion 301 and a second protrusion 401 at the ends of the metal finger electrode 3 and the waterproof insulating sleeve 4 near the flexible circuit board 2, respectively. By providing the first protrusion 301 and the second protrusion 401 at the ends of the metal finger electrode 3 and the waterproof insulating sleeve 4 near the flexible circuit board 2, the assembly between the metal finger electrode 3 and the waterproof insulating sleeve 4 can be more securely achieved, preventing separation of the metal finger electrode 3 and the waterproof insulating sleeve 4. Simultaneously, it also prevents the assembly of the metal finger electrode 3 and the waterproof insulating sleeve 4 from falling out of the mounting opening of the watch body 1, effectively improving the stability of the metal finger electrode 3 and the waterproof insulating sleeve 4 installed in the mounting opening of the watch body 1.

[0045] Reference Figure 11 , Figure 12Furthermore, the waterproof insulating sleeve 4 has waterproof ribs, and a waterproof rubber ring 402 is fitted onto the waterproof ribs of the waterproof insulating sleeve 4. By installing the waterproof rubber ring 402 at the waterproof ribs of the waterproof insulating sleeve 4, when the waterproof insulating sleeve 4 is installed into the mounting opening of the watch body 1, the waterproof rubber ring 402 can be used to seal the gap between the inner wall of the mounting opening and the waterproof insulating sleeve 4, thereby further improving the waterproof effect.

[0046] Reference Figure 11 Furthermore, the waterproof insulating sleeve 4 is made of silicone. The use of silicone material to make the waterproof insulating sleeve 4 can improve its flexibility, thus making it easier for the waterproof insulating sleeve 4 to fit more tightly with the inner wall of the mounting opening of the watch body 1 and the metal finger electrode 3 when squeezed, further improving the waterproof effect of the smartwatch.

[0047] Example 4:

[0048] Reference Figure 5 , Figure 13 A smartwatch with an insulated and waterproof structure for finger electrodes is basically the same as in embodiment 3. Furthermore, a wave-shaped washer 6 is installed between the flexible circuit board 2 and the metal finger electrode 3 through a locking screw 5. By installing the wave-shaped washer 6 between the flexible circuit board 2 and the metal finger electrode 3, when the locking screw 5 connects the flexible circuit board 2 and the metal finger electrode 3, the wave-shaped washer 6 can make the flexible circuit board 2 and the metal finger electrode 3 make more sufficient contact, which effectively improves the stability of the metal finger electrode 3 when sending signals to the main control chip 101 through the flexible circuit board 2.

[0049] Reference Figure 9 A positioning groove 201 is provided on the side of the flexible circuit board 2 near the metal finger electrode 3. The waveform pad 6 is limited in the positioning groove 201 of the flexible circuit board 2. By providing a positioning groove 201 on the flexible circuit board 2, when the waveform pad 6 is fixed between the flexible circuit board 2 and the metal finger electrode 3 by the locking screw 5, the waveform pad 6 can be positioned to prevent the waveform pad 6 from shifting and affecting the installation of the waveform pad 6, thus effectively improving the stability of the waveform pad 6.
