[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] The core of this invention is to provide a waterproof button structure for a smart wearable device and a smart wearable device including the waterproof button structure, wherein the waterproof button structure has good waterproof performance.

[0035] This invention provides a specific embodiment of a waterproof button structure for smart wearable devices, which can be applied to smartwatches. Please refer to... Figures 1 to 5 The waterproof button structure includes a housing 4, a pressure plate 3, and a button 1.

[0036] A receiving hole 412 is provided through the housing 4, and a pressure plate 3 is fixedly provided on the housing 4. The pressure plate 3 is in a sealing fit with the outer periphery of the housing 4 located at the outer port of the receiving hole 412. Unless otherwise specified, in this application, "inner" and "outer" refer to directions closer to the interior space of the housing 4 as the inward direction, and directions closer to the exterior space of the housing 4 as the outward direction, with the housing 4 as the reference. Figure 2 Taking the directions shown as an example, the bottom of the diagram represents the inward direction, and the top represents the outward direction.

[0037] The pressure plate 3 has a pressure plate mounting hole 312 that communicates with the receiving hole 412. The button 1 extends into the receiving hole 412 through the pressure plate mounting hole 312. The button 1 is sealed to the pressure plate mounting hole 312, and the button 1 can slide relative to the housing 4; that is, the button 1 can slide relative to both the receiving hole 412 and the pressure plate mounting hole 312. A sealing ring is provided between the wall of the receiving hole 412 and the button 1 to prevent water leakage. Of course, in other embodiments, the button 1 can also be rotatably connected to the housing 4.

[0038] Among them, such as Figure 2 As shown, due to the need to install a sealing ring, there is a gap between the button 1 and the wall of the receiving hole 412, and the sealing fit between the pressure plate mounting hole 312 and the button 1. Accordingly, the diameter of the receiving hole 412 will be larger than the diameter of the pressure plate mounting hole 312, and the pressure plate 3 will block the outer port of the receiving hole 412 (i.e., Figure 2 The portion located between button 1 and the wall of the receiving hole 412 in the upper port of the receiving hole 412.

[0039] In this embodiment, the sealing connection between the pressure plate 3 and the housing 4, and the setting of the sealing ring, can seal the button 1 and the housing 4, achieving multiple waterproofing for the button 1, ensuring waterproof performance, and effectively preventing external liquids from entering the housing 4 through the gap between the receiving hole 412 and the button 1.

[0040] Furthermore, the sealing ring is elastic, and the elastic force it provides gives button 1 a tendency to return to its original position. In this embodiment, button 1, when subjected to pressing pressure, returns to its original position... Figure 2The button 1 initially moves towards the inside of the housing 4, increasing the elastic deformation of the sealing ring. After the pressure is released, the button 1 moves outward from the housing 4 under the elastic restoring force of the sealing ring until it returns to its initial position. Because the sealing ring is elastic, it can provide cushioning and shock absorption for the button 1, and there is no need for a separate reset structure. The button 1 can be reset simply by using the sealing ring, which simplifies the structure and reduces the number of parts.

[0041] Furthermore, such as Figure 2 and Figure 3 As shown, the sealing ring includes a conical ring, with its small-diameter end sealingly connected to the button 1 and its large-diameter end sealingly connected to the receiving hole 412. Using a sealing ring with a conical shape increases the sealing ring area, thereby increasing the travel of the button 1. Preferably, the conical ring can be a corrugated sealing ring, which has higher structural strength.

[0042] Furthermore, such as Figure 2 and Figure 3 As shown, there are two sealing rings, namely the first sealing ring 5 and the second sealing ring 6. Along the direction towards the inside of the housing 4, the small-diameter end of the conical ring in the first sealing ring 5 and the small-diameter end of the conical ring in the second sealing ring 6 sequentially seal and connect to the button 1. The large-diameter end of the conical ring in the first sealing ring 5 seals and connects to the outer port of the receiving hole 412 (i.e.,...). Figure 2 In the middle, the upper port of the receiving hole 412), the large diameter end of the conical ring in the second sealing ring 6 seals the connection to the inner port of the receiving hole 412 (i.e., the upper port of the receiving hole 412). Figure 2 In the middle (the lower port of the receiving hole 412), the first sealing ring 5 and the second sealing ring 6 are arranged sequentially from the outside to the inside in the receiving hole 412, which can achieve two levels of waterproofing. From the outside to the inside, the pressure plate 3 performs the first level of waterproofing, the first sealing ring 5 performs the second level of waterproofing, and the second sealing ring 6 performs the third level of waterproofing, further increasing the waterproofing capability. In other embodiments, the sealing rings can also be set to one, three, or other numbers.

[0043] Furthermore, such as Figure 4 As shown, an annular groove is provided on the outer surface of button 1. The sealing ring is sealed and fixedly connected to the annular groove, which can ensure the reliability of the connection between button 1 and the sealing ring and reliably position the small-diameter end of the sealing ring to button 1. Specifically, along the direction from the outside to the inside, two annular grooves, a first annular groove 113 and a second annular groove 114, are provided on button 1 in sequence. The first sealing ring 5 is fixed to the first annular groove 113, and the second sealing ring 6 is fixed to the second annular groove 114. Of course, in other embodiments, the sealing ring and button 1 can also be bonded and fixed. In addition, the sealing ring and the wall of the receiving hole 412 can be sealed and fixedly connected by interference fit.

[0044] Furthermore, such as Figure 2As shown, a limiting plate 7 is fixedly installed at the inner end of the button 1. The limiting plate 7 is located inside the housing 4. The limiting plate 7 abuts against the housing 4 to prevent the button 1 from coming out of the receiving hole 412, thus effectively preventing the button 1 from coming out of the housing 4. Specifically, when the button 1 moves inward, the limiting plate 7 abuts against the portion of the housing 4 located on the outer periphery of the inner port of the receiving hole 412 to prevent the button 1 from coming out of the receiving hole 412.

[0045] Furthermore, button 1 is threadedly connected to limit plate 7. Specifically, as shown... Figure 2 and Figure 3 As shown, the limiting plate 7 includes a limiting part 711 and a limiting stud 713 protruding from the outer end face of the limiting part 711. The limiting plate 7 limits the button 1 by abutting the limiting part 711 against the housing 4. At the same time, the inner end of the button 1 is provided with a button threaded hole 115, which is threadedly connected to the limiting stud 713.

[0046] In addition, to achieve the triggering function of button 1, specifically, as follows: Figure 2 As shown, a button trigger 712 is provided on the inner end face of the limiting plate 7, and a PCB board 8 is provided inside the housing 4. A circuit board 812 and a switch element 811 electrically connected to the circuit board 812 are provided on the PCB board 8. When the limiting plate 7 moves into the housing 4 synchronously with the button 1, the button trigger 712 gradually approaches the switch element 811 until it triggers the switch element 811, and the circuit board 812 performs the corresponding action.

[0047] Compared to the existing technology that typically uses a C-shaped retaining ring to connect to the button 1 to prevent the button 1 from coming out of the housing 4, the existing button 1 assembly efficiency is low because the retaining ring has a large preload and requires special assembly tools. The threaded connection used in this embodiment helps to simplify the assembly steps and improve the efficiency of the production line.

[0048] Furthermore, such as Figure 2 As shown, button 1 includes a button post 112 and a pressing plate 111 fixed to the outer end of the button post 112. The button post 112 extends into the receiving hole 412 through the pressure plate mounting hole 312. The button post 112 and the pressure plate mounting hole 312 are sealed and slidably connected, and a sealing ring is provided between the button post 112 and the receiving hole 412. The pressing plate 111 is located outside the pressure plate 3, and in the sliding direction perpendicular to the button 1, at least a portion of the pressing plate 111 protrudes from the outer periphery of the pressure plate mounting hole 312.

[0049] In the initial state, such as Figure 2 As shown, there is a gap between the pressing plate 111 and the pressure plate 3 in the inward and outward directions, which is the travel space of the button 1. During the inward sliding process of the button 1, the pressing plate 111 and the pressure plate 3 abut against each other, which can limit the extreme position of the inward movement of the button 1 and avoid excessive deformation of the sealing ring.

[0050] Furthermore, such as Figure 2 and Figure 5 As shown, a mounting groove 411 is also provided on the outer end of the housing 4 at the receiving hole 412. The mounting groove 411 and the receiving hole 412 form a stepped structure, and the pressing plate 3 is built into the mounting groove 411.

[0051] Specifically, such as Figures 2 to 5 As shown, the pressure plate 3 is provided with a pressure plate positioning hole 311 for connecting the positioning screw 2. The pressure plate 3 is locked into the screw groove 413 on the mounting groove 411 by the positioning screw 2. The screw nut 211 protrudes from the outer end face of the pressure plate 3. Correspondingly, a groove 116 is provided on the inner end face of the pressing plate 111. During the movement of the button 1 into the housing 4, when the pressing plate 111 abuts against the pressure plate 3, at least part of the structure of the pressing plate 111 is located in the mounting groove 411, and the groove 116 covers the nut 211 accordingly, which can ensure the comfort of pressing the button 1.

[0052] Furthermore, such as Figure 2 As shown, a guide plate 414 is also fixedly installed on the inner port of the housing 4 at the receiving hole 412, and a guide hole 4141 is provided through the guide plate 414, as shown. Figure 2 As shown, the guide plate 414, the receiving hole 412, and the mounting groove 411 form a stepped structure. The outer end face of the guide plate 414 and the bottom of the mounting groove 411 form two outward-facing stepped surfaces. The button 1 is fitted and connected to the guide hole 4141, and the two are slidably engaged. Specifically, the button top post 112 in the button 1 is fitted and engaged with the guide hole 4141, which can prevent the button 1 from shaking during movement.

[0053] The waterproof button structure in this embodiment has the following beneficial effects:

[0054] I. Strong Waterproofing Capability: The housing 4 has a mounting groove 411, and the pressure plate 3 is installed in the mounting groove 411, forming the first level of waterproofing for the button 1. The small-diameter end of the first sealing ring 5 is installed on the first annular groove 113 of the button top post 112, and the large-diameter end is interference-fitted with the receiving hole 412, achieving the second level of waterproofing. The second sealing ring 6 is installed opposite to the first sealing ring 5, forming a symmetrical structure. The small-diameter end of the second sealing ring 6 is installed on the second annular groove 114 of the button top post 112, and the large-diameter end is interference-fitted with the receiving hole 412, achieving the third level of waterproofing. This effectively prevents external moisture from entering the interior of the housing 4, specifically serving as a 5ATM waterproof button. In addition, since the annular groove can limit the sealing ring, preventing the sealing ring from moving in the direction of movement of the button 1 or in its position relative to the button 1 during use, the waterproofing effect can be further guaranteed.

[0055] II. Simple Structure: No additional elastic components are needed; the elasticity of the sealing ring directly achieves extension and buffering, as well as the reset of button 1, reducing the risk of button jamming. When button 1 is pressed, the sealing ring undergoes increased elastic deformation under external pressure, causing the button top post 112 to move downwards. Button 1 is limited in the downward direction by the pressure plate 3. After the external force is removed, the sealing ring extends upwards in the opposite direction under its own elastic force, and button 1 returns to its initial state. During the button 1 reset process, the limiting part 711 can limit button 1 in the upward direction, while preventing button 1 from detaching from the housing 4.

[0056] 3. Easy assembly: The limit plate 7 and the button 1 are directly connected by threads, without the need for other special tools.

[0057] In addition to the aforementioned waterproof button structure for smart wearable devices, this invention also provides a smart wearable device comprising a main body, on which a waterproof button structure is disposed, specifically, the waterproof button structure described in any of the above embodiments. The housing 4 in the waterproof button structure can be integrally formed onto the outer shell of the main body.
