Description

Technical Field

[0001] The utility model relates to the technical field of wearable devices, in particular to a waterproof sealing component for wearable devices. Background Art

[0002] Wearable devices are external devices that can be worn on the body. They come in a wide variety of types, including smart bracelets, smart glasses, exoskeletons, and wearable headbands. Regardless of the device, they all have buttons or touch screens on the outside for user operation. Therefore, the gaps in these devices become crucial for waterproofing. Some existing devices address this by adding sealing gaskets at the gaps connecting the buttons and the outer casing to reduce water infiltration. However, when a button is pressed, it moves vertically relative to the outer casing, creating friction on the gasket. Over time, this can cause wear on the gasket surface, leading to a poor sealing effect. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-6 The utility model provides a technical solution: it includes a device body 10 and a vertical through channel 1 arranged on one side of the top of the device body 10, a button 11 is slidably connected in the channel 1, a sealing gasket 13 is fixedly connected to the bottom of the button 11, a sleeve rod 30 is fixedly connected to the bottom of the sealing gasket 13, a sleeve rod 2 31 is sleeved on the bottom end of the outer arc wall of the sleeve rod 1 30, and a fixing mechanism 20 is fixedly connected to the top of the sleeve rod 2 31, the button 11 and the sealing gasket 13 are both located in the fixing mechanism 20, the sleeve rod 1 30 and the sleeve rod 2 31 are both hollow structures, a spiral rod 32 is fixedly connected to the inner wall of the top of the sleeve rod 1 30, and the spiral rod 32 is far away One end of the sleeve rod 30 is located inside the sleeve rod 2 31, and the bottom of the sleeve rod 2 31 is rotatably connected to a horizontal turntable 33. A spiral channel 2 adapted to the screw rod 32 is provided at the center of the top of the turntable 33. The end of the screw rod 32 away from the sleeve rod 1 30 is engaged with the channel 2. A base 35 is provided at the bottom of the turntable 33, and the base 35 is fixedly connected to the bottom inner wall of the equipment body 10. An annular groove is provided on the top of the base 35. Several vertical support plates 34 distributed in a circular array are fixedly connected to the bottom edge of the turntable 33, and the ends of several support plates 34 away from the turntable 33 are all slidably connected to the annular groove.

[0029] It should be noted that the cross-sectional radius of the sealing gasket 13 is larger than that of the button 11. In the initial state, the top of the button 11 is located outside the device body 10, and the sealing gasket 13 abuts against the inner wall of the top of the device body 10 to seal the gap. When the button 11 is pressed, the sealing gasket 13 moves away, and the fixing mechanism 20 closes to continuously seal the gap. When the button 11 is pressed, the sleeve rod 1 30 slides inside the sleeve rod 2 31.

[0030] In fact, a spring telescopic rod is provided inside the spiral rod 32, and a protrusion 1 is provided on the outer arc wall of the sleeve rod 1 30. When the sleeve rod 1 30 is pressed to a certain extent, the spring telescopic rod is compressed, and the spiral rod 32 drives the turntable 33 to rotate, while the fixing mechanism 20 is closed. In this way, the turntable 33 can be rotated and reset without affecting the fixing mechanism 20.

[0031] See also Figure 4-Figure 5 The present utility model provides a technical solution: the fixing mechanism 20 includes a fixing plate 25 fixedly connected to the top of the sleeve rod 31, and a rotating ring 22 is rotatably connected to the outer arc wall of the fixing plate 25. The axial extension direction of the rotating ring 22 is arranged away from the turntable 33, and a plurality of fixing rods 23 distributed in a ring array are rotatably connected to the side wall of the rotating ring 22 away from the fixing plate 25. The ends of the plurality of fixing rods 23 away from the rotating ring 22 are rotatably connected to the limiting plate 24, and the top of the rotating ring 22 is rotatably connected to the top of the top plate 21. A vertical channel three is provided at the center of the top of the top plate 21 and the top of the fixing plate 25. The cross-sectional radius of the channel three is greater than the cross-sectional radius of the sealing gasket 13 and the cross-sectional radius of the inner arc wall of the sleeve rod 31. The top of the top plate 21 abuts against the inner wall of the top of the equipment body 10.

[0032] It should be noted that the side wall of the limiting plate 24 away from the fixing plate 25 is in contact with the bottom of the top plate 21. The top plate 21 is not only used to limit the limiting plate 24, but also to limit the trajectory of water seeping into the gap between the button 11 and the device body 10 to prevent water from splashing through the sealing gasket 13 when it falls in. Channel three is used for the button 11 and the sealing gasket 13 to pass through.

[0033] See also Figure 5The present utility model provides a technical solution: several of the limit plates 24 are located at the top of the fixed plate 25 and are located inside the rotating ring 22. The cross-section of the limit plate 24 is crescent-shaped, and the end of the fixing rod 1 23 away from the rotating ring 22 is rotatably connected to the middle of the limit plate 24. The other end of the limit plate 24 away from the fixing rod 1 23 and closer to the fixing rod 1 23 is rotatably connected to the top of the fixed plate 25. When the several limit plates 24 rotate and shrink toward the inner center of the rotating ring 22, the several limit plates 24 can close the channel three. When the several limit plates 24 rotate and open away from the inner center of the rotating ring 22, the several limit plates 24 do not block the channel three. The outer side of the bottom of the fixed plate 25 is fixedly connected with 42, and the other end of 42 away from the fixed plate 25 is installed on the top of the base 35.

[0034] It should be noted that the top of the fixing plate 25, that is, the side wall where the fixing plate 25 contacts the limiting plate 24, is a slope. The height at the center of the top of the fixing plate 25 is higher than the height at its edge. After water enters, it is blocked by the sealing gasket 13 and spreads around, and is then blocked by the top plate 21 and falls into the fixing mechanism 20, and then falls on the top surface of the fixing plate 25, and finally converges at 42.

[0035] See also Figure 2 The utility model provides a technical solution: a vertical slide groove 1 is provided at the center of the top of the base 35, and a drainage channel 43 is provided at the bottom end of the slide groove 1, which passes horizontally through the outer arc wall of one side of the base 35. The slide groove 1 and the drainage channel 43 are interconnected, and a limiting post 50 is slidably connected in the slide groove 1. The end of the limiting post 50 close to the turntable 33 is located directly below the channel 2, and the end of the limiting post 50 away from the turntable 33 is an inclined surface, and the inclined surface is arranged toward the drainage channel 43. The bottom end of the inner arc wall of the drainage channel 43 is slidably connected to a sliding rod 52, and the end of the top of the sliding rod 52 close to the slide groove 1 is fixedly connected to a wedge block 51. The end of the wedge block 51 close to the limiting post 50 is an inclined surface, and the wedge block 51 is adapted to the inclined surface on the side wall close to the limiting post 50.

[0036] It should be noted that: a vertical slide groove 2 is provided on the inner arc wall of the slide groove 1, and a protrusion 2 is provided on the outer arc wall of the limit column 50. The protrusion 2 is slidably connected to the slide groove 2, and a spring 2 is fixedly connected to the bottom of the protrusion 2. The bottom of the spring 2 is fixedly connected to the inner wall of the bottom of the slide groove 2. In this way, when the spiral rod 32 presses down to push the limit column 50, it will squeeze the wedge block 51 and then push the slide rod 52. When resetting, the spring 2 can reset the limit column 50.

[0037] See also Figure 1-Figure 2The present utility model provides a technical solution: the cross-sectional radius of the inner arc wall of the end of the drain channel 43 away from the slide groove 1 is larger than the cross-sectional radius of the inner arc wall of the end of the drain channel 43 close to the slide groove 1, the top of the slide rod 52 is fixedly connected to the limiting bead 53 at the end away from the wedge block 51, and the limiting bead 53 is fixedly connected to a spring 1 54 on the side wall away from the wedge block 51, and the spring 1 54 is coaxially arranged with the drain channel 43, and the end of the spring 1 54 away from the limiting bead 53 is fixedly connected to the limiting ring 55, which is fixedly connected to the inner arc wall of the drain channel 43, and the limiting ring 55 is coaxially arranged with the drain channel 43.

[0038] It should be noted that the limiting ring 55 provides support for the spring 1 54 . The cross-sectional radius of the opening of the limiting ring 55 at the end close to the spring 1 54 is smaller than the cross-sectional radius at the end away from the spring 1 54 . That is, the through hole of the limiting ring 55 is truncated cone-shaped with the small opening facing the outside of the device body 10 to reduce the ingress of external impurities.

[0039] In addition, the cross-sectional radius of the two parts of the drainage channel 43 is different. The limiting bead 53 is located in the area with a larger cross-sectional radius of the drainage channel 43 and abuts against the opening of the drainage channel 43 from the area with a smaller radius to the area with a larger radius.

[0040] See also Figure 2 The utility model provides a technical solution: the top of the turntable 33 is located outside the sleeve rod 31 and is fixedly connected to a plurality of fixed ear seats 40. A spherical groove is provided on the side wall of the fixed ear seat 40 away from the turntable 33. The bottom of the rotating ring 22 is fixedly connected to the same number of fixed ear seats 40 with the same structure. The two fixed ear seats 40 located on the same vertical line and close to each other are rotatably connected to the same fixed rod 41 at one end. Both ends of the fixed rod 41 are fixedly connected to a universal ball, and the universal ball is rotatably connected to the spherical groove.

[0041] It should be noted that when the turntable 33 rotates, the torque is transmitted through the fixed ear seat 40, that is, the second fixed rod 41, to drive the rotating ring 22 to rotate, thereby driving the fixing mechanism 20 to work.

[0042] See also Figure 2 The utility model provides a technical solution: the end of the 42 away from the fixed plate 25 passes through the top of the base 35 and is interconnected with the drainage channel 43, and the 42 is located between the annular slide groove and the limiting bead 53.

[0043] It should be noted that the limiting bead 53 is further away from the sleeve rod 31 42 than the annular groove. The limiting bead 53 is used to divert water from the top of the fixing plate 25 into the drain channel 43 , but is still controlled by the limiting bead 53 .

[0044] See also Figure 1The present invention provides a technical solution: both side walls of the device body 10 are provided with a horizontally penetrating drain port 12 at one end close to the button 11 , and the drain port 12 and the drain channel 43 are interconnected.

[0045] It should be noted that after the button 11 is pressed to trigger the limit bead 53 to be pushed open, the water inside the drain channel 43 will flow out and be discharged from the drain port 12 to the outside of the device body 10.

[0046] Working principle:

[0047] When the button 11 is pressed, the screw rod 32 is driven downward. When the screw rod 32 passes through the spiral channel 2 at the center of the top of the turntable 33, the turntable 33 is driven to rotate. The turntable 33 drives the fixing mechanism 20 to clamp and fix the outer arc wall of the button 11 through the fixing ear seat 40 and the fixing rod 2 41. At this time, if water flows into the gap between the button 11 and the device body 10, it will be intercepted by the fixing mechanism 20 and fall into the fixing plate 25. Due to the inclined surface of the top of the fixing plate 25, the water flows toward the bottom edge 42 of the fixing plate 25 and flows into the drain channel 43 through 42.

[0048] In addition, when the button 11 is pressed, the spiral rod 32 will push the limiting column 50 after passing through the channel 2, so that it pushes the wedge block 51 and the slide rod 52 to move, and then pushes the limiting bead 53 to release the obstruction of the drain channel 43, so that the water in the drain channel 43 can be discharged. After the button 11 is released, the components are reset, and the limiting bead 53 re-closes the drain channel 43 to prevent water from entering the interior of the device from the drain channel 43.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any form. Although the present invention has been disclosed as above with preferred embodiments, they are not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
