Figure 2 yes Figure 1 A partial structural diagram of an electronic device. Figure 3 yes Figure 2 A schematic diagram of the exploded structure of an electronic device.

[0022] The wearable device 10a provided in this application embodiment can be a smartwatch, which can be worn on a user's wrist. Besides providing services such as calendar and time viewing, it can also provide communication services such as voice calls and video chats, and monitor the user's daily exercise and health data.

Figure 1 As shown, the wearable device 10a may include an electronic device 10 and a strap 20. The electronic device 10 may have an electrocardiogram (ECG) detection function, and straps 20 may be provided on both opposite sides of the electronic device 10 to allow the user to wear the electronic device 10 on their wrist. In this embodiment, the ECG detection function of the electronic device 10 has the advantages of high sensitivity and high reliability, and the casing of the electronic device 10 also has the advantage of high assembly reliability, improving the waterproof performance and aesthetic appeal of the electronic device 10.

[0023] The electronic device 10 can contain various components, such as batteries, control circuit boards, and various sensors, to achieve the functions required by the wearable device 10a. Figures 1 to 3 As shown, the electronic device 10 may be the head unit of the wearable device 10a. The electronic device 10 includes, but is not limited to, the following structures: display screen 100, mid-frame 200, back cover (not shown), insulating component 300, and conductive component 400.

[0024] Specifically, the display screen 100 and the back cover are respectively matched with the middle frame 200 to form a receiving space, which is used to accommodate various components of the electronic device (not shown in the figure), such as batteries, control circuit boards and various sensors.

[0025] Please refer to the following: Figure 4 and Figure 5 , Figure 4 yes Figure 2 A cross-sectional view of the electronic device in the embodiment. Figure 5 yes Figure 4 The enlarged schematic diagram of a partial structure at point A shows that the middle frame 200 is made of a conductive material, specifically a metal, alloy, or graphite-based composite material, serving as the carrier for the button function and providing support for the overall structure. The middle frame 200 has mounting holes 210 connecting its inner and outer sides. It can be understood that "the middle frame is made of a conductive material" means that part or all of the material used to make the middle frame is conductive. For example, the middle frame is made of metal, and the conductive element is a metal key. For example, the metal key includes an ECG electrode and / or a body fat detection electrode. Optionally, please also refer to... Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the structure of one embodiment of the insulating component in this embodiment. Figure 7 yes Figure 6 The embodiment shows a schematic diagram of the insulating component from another perspective. The insulating component 300 can be made of plastic, while the conductive component 400 can be made of conductive materials such as metal, alloy, or graphite-based composite material. The insulating component 300 is used to insulate the conductive component 400 from the middle frame 200. In this embodiment, the insulating component 300 includes a first insulating part 310 and a second insulating part 320 with an integral structure. The first insulating part 310 is fixedly connected to the outer side of the middle frame 200, and the second insulating part 320 is inserted into the mounting hole 210. A through connecting hole 321 is provided in the middle of the second insulating part 320.

[0026] Alternatively, please continue reading Figure 5 The outer side of the middle frame 200 is provided with a receiving groove 220. The first insulating part 310 of the insulating member 300 is at least partially embedded in the receiving groove 220, and the first insulating part 310 is bonded and fixed to the middle frame 200 by applying glue in the receiving groove 220.

[0027] Please refer to the following: Figure 8 , Figure 8 This is a schematic diagram of one embodiment of the conductive component 400. The conductive component 400 includes an integral keycap 410 and a connecting rod 420. Optionally, in this embodiment, the keycap 410 has a straight-line structure, i.e., a strip structure. The keycaps on both sides of the connection position between the connecting rod 420 and the keycap 410 have different lengths. That is, the connecting rod 420 is not connected to the middle of the keycap 410, but is offset to one side, resulting in different keycap lengths on both sides of the connecting rod 420. One reason for this design is that the internal stacking space of the electronic device makes it impossible to set the connecting rod in the exact center of the conductive component 400, or to set a hole in the exact center of the keycap 410 to accommodate and pass through the connecting rod 420 so that the connecting rod 420 corresponds to internal components.

[0028] The keycap 410 is fixedly connected to the first insulating part 310, and the two can be bonded together by adhesive. A connecting rod 420 is inserted into the connecting hole 321, and the end of the connecting rod 420 away from the keycap 410 is used to connect to the control circuit of the electronic device (not shown). The conductive element 400 serves as the contact point for the electrocardiogram (ECG) signal, enabling signal detection. For example, the control circuit includes an ECG detection circuit and / or a body fat detection circuit.

[0029] Alternatively, please continue reading Figure 3 and Figure 5 In this embodiment, the electronic device 10 may also include a metal conductive connecting piece 500. The conductive connecting piece 500 is disposed inside the middle frame 200 and is welded to the end of the conductive member connecting rod 420 away from the keycap 410. That is, the conductive member 400 is conductively connected to the control circuit through the conductive connecting piece 500.

[0030] Alternatively, please continue reading Figure 5 and Figure 8 The connecting rod 420 of the conductive component is provided with an annular groove 421 located inside the connecting hole 321 of the second insulating part. A first waterproof rubber ring 600 is provided in the annular groove 421. The first waterproof rubber ring 600 is used for waterproofing between the connecting rod 420 and the inner wall of the connecting hole 321. The first waterproof rubber ring 600 is used to achieve the first channel waterproofing of the button, reaching the 5ATM level.

[0031] Please continue reading. Figure 5 The outer side of the second insulating part 320 of the insulating component 300 is provided with a second waterproof rubber ring 700. The second waterproof rubber ring 700 is used for waterproofing between the second insulating part 320 and the inner wall of the middle frame mounting hole 210, so as to realize the second channel waterproofing of the button.

[0032] Please continue reading for more details. Figure 5 and Figure 7 as well as Figure 8 The first insulating portion 310 of the insulating component 300 has a mounting groove 311 on the side opposite to the middle frame 200. Correspondingly, the keycap 410 has a protrusion 411, which is inserted into the mounting groove 311 and fixed by adhesive. This staggered design of the conductive component 400 and the insulating component 300 can maximize the area of ​​the keycap 410. By designing the structure in which the protrusion 411 mates with the mounting groove 311, the contact area between the conductive component 400 and the insulating component 300 can be increased, thereby improving the bonding reliability.

[0033] Optionally, the mounting groove 311 on the first insulating part 310 may include a first mounting groove 3111 and a second mounting groove 3112 located on opposite sides of the connecting hole 321, wherein the lengths of the first mounting groove 3111 and the second mounting groove 3112 are different; correspondingly, the protrusion 411 on the keycap 410 includes a first protrusion 4111 and a second protrusion 4112 located on opposite sides of the connecting rod 420, wherein the first protrusion 4111 and the second protrusion 4112 correspond one-to-one with the first mounting groove 3111 and the second mounting groove 3112 and are adapted in size, the first protrusion 4111 and the second protrusion 4112 are respectively inserted into the first mounting groove 3111 and the second mounting groove 3112, and are respectively fixedly connected by adhesive. By designing the first mounting groove 3111 and the second mounting groove 3112 to have different lengths (correspondingly, the first protrusion 4111 and the second protrusion 4112 have different lengths), i.e., an asymmetrical design, the purpose of preventing mistaken installation can be achieved. In addition, in some other embodiments, the first mounting groove 3111 and the second mounting groove 3112 may be designed with different depths (or a combination of the two). Correspondingly, the first protrusion 4111 and the second protrusion 4112 on the keycap 410 are also designed with different protrusion heights, which can also play a foolproof role. The detailed features of this part are within the understanding of those skilled in the art, and will not be listed and described in detail here.

[0034] Alternatively, please continue reading Figure 5 In this embodiment, the keycap 410 is located on the side of the first insulating part 310 away from the second insulating part 320. The area of ​​the first insulating part 310 is larger than the area of ​​the keycap 410, and the four peripheral edges of the first insulating part 310 are exposed on the keycap 410 or the four peripheral edges of the first insulating part 310 surround the keycap 410, separating the keycap 410 from the middle frame 200, thereby achieving insulation between the keycap 410 and the middle frame 200.

[0035] Optionally, please continue. Figure 3 , Figure 5 as well as Figure 8 The electronic device in this embodiment also includes a retaining ring 800 and an insulating gasket 900. The connecting rod 420 of the conductive member 400 has a retaining ring groove 422. The retaining ring 800 is fixedly connected to the retaining ring groove 422. The retaining ring 800 can be made of metal, specifically a C-shaped steel sheet, which is snapped into the retaining ring groove 422 and welded to the connecting rod 420. The retaining ring 800 is used to fix the conductive member 400 and the insulating member 300, enhancing the structural stability. The insulating gasket 900 is disposed between the retaining ring 800 and the inner wall of the middle frame 200, and is used to insulate the retaining ring 800 from the middle frame 200.

[0036] The installation process of the components related to the ECG button function in the electronic device in this embodiment is as follows: First, the first waterproof rubber ring 600 is installed in the annular groove 421 of the conductive connecting rod 420 to achieve the first channel waterproofing (5ATM); then, the conductive part 400 and the insulating part 300 with the first waterproof rubber ring 600 installed are fixed by applying glue; the second waterproof rubber ring 700 is sleeved on the second insulating part 320 of the insulating part 300 to achieve the second layer of waterproofing; then, the button assembly (including the insulating part 300 and the conductive part 400) with the second waterproof rubber ring 700 installed is placed into the mounting hole of the middle frame 200 and fixed with glue; the retaining ring 800 is assembled and fixed by welding to prevent the conductive part from falling off during long-term use; finally, the conductive connecting piece 500 is welded to the conductive part to connect and realize the ECG circuit function.

[0037] The electronic device in this application embodiment not only simplifies the assembly process, but also makes the waterproofing method more stable and reliable, improves the utilization of structural space, and reduces the overall thickness.
