[0048] like Figures 1-8 As shown, a wrist-worn electronic device includes a main body 1, a sensing device 2, and a wristband 3.

[0049] The main body 1 has a protruding first contact portion 11 on the side facing the user's wrist 101, and the sensing device 2 is located inside the main body 1 and faces the first contact portion 11;

[0050] The main body 1 also has a second contact portion 12 on the side facing the user's wrist 101. The second contact portion 12 is located at the outer edge of the first contact portion 11 and is connected to the first contact portion 11. The second contact portion 12 has a first concave-convex structure 5, and a first air flow channel 7 is formed between the second contact portion 12 and the user's wrist 101 through the first concave-convex structure 5.

[0051] The wristband 3 is disposed at both ends of the main body 1. The side of the wristband 3 facing the user's wrist 101 has a second concave-convex structure 6. A second airflow channel 8 is formed between the wristband 3 and the user's wrist 101 through the second concave-convex structure 6.

[0052] Among them, the first contact part 11, the second contact part 12 and the side of the wristband 3 facing the user's wrist 101 are also provided with an antibacterial layer 4.

[0053] The application effectively improves the contact between the sensing device 2 and the skin, improves the detection accuracy in the wearing state, by setting the protruding first contact part 11 and the sensing device 2 towards the first contact part 11 on the main body 1; at the same time, by setting the first concave-convex structure 5 on the second contact part 12 and the second concave-convex structure 6 on the wrist strap 3, the first concave-convex structure 5 and the user's wrist 101 form a first air flow channel 7, and the second concave-convex structure 6 and the user's wrist 101 form a second air flow channel 8, effectively increasing the gap between the device and the skin, promoting air circulation, reducing the stuffy feeling when wearing for a long time, and significantly improving the wearing comfort of the user. Further, the first contact part 11, the second contact part 12 and the wrist strap 3 towards the user's wrist 101 are all provided with a bacteriostatic layer 4, which effectively inhibits bacterial growth and reduces the risk of bacterial transmission when the skin contacts the device, providing a more healthy and safe wearing environment for the user.

[0054] Specifically, the bacteriostatic layer 4 includes a silver ion coating or a nano-copper coating. The application uses silver ion or nano-copper material to effectively inhibit the growth of various bacteria, and the antibacterial effect is durable and stable, safe and reliable to use, providing a more comprehensive wearing experience for the user.

[0055] As shown in Figure 2 , 3 , 5, the first concave-convex structure 5 includes a plurality of first recessed parts 51 arranged at intervals and first protruding parts 52 located between the first recessed parts 51, the first protruding parts 52 being in contact with the user's wrist 101, and the first recessed parts 51 forming the first air flow channel 7 with the user's wrist 101.

[0056] And / or, the second concave-convex structure 6 includes a plurality of second recessed parts 61 arranged at intervals and second protruding parts 62 located between the second recessed parts 61, the second protruding parts 62 being in contact with the user's wrist 101, and the second recessed parts 61 forming the second air flow channel 8 with the user's wrist 101.

[0057] The first protruding part 52 of the application is in close contact with the user's wrist 101, making the device more stable when worn; at the same time, the first recessed part 51 forms the first air flow channel 7 with the user's wrist 101, effectively promoting air circulation and reducing the stuffy feeling when worn. Similarly, the second protruding part 62 and the second recessed part 61 in the second concave-convex structure 6 also have similar effects, ensuring the stability of the wearing and enhancing the air permeability. The wrist-worn electronic device of the application not only improves the wearing comfort of the user, but also keeps the device dry for a long time, providing a more superior wearing experience for the user.

[0058] The connection between the first recess 51 and the first protrusion 52 is smoothly transitioned, and the connection between the second recess 61 and the second protrusion 62 is also smoothly transitioned. The smooth transition design reduces the extrusion on the user's wrist 101, and improves the wearing comfort of the user.

[0059] Specifically, as shown in Figure 2 , the first recess 51 includes a point-shaped recess, and a plurality of point-shaped recesses are randomly arranged on the second contact portion 12; or as shown in Figure 3 , the first recess 51 includes a strip-shaped recess, and a plurality of strip-shaped recesses are arranged in the length direction or the width direction of the second contact portion 12.

[0060] In one embodiment, as shown in Figure 2 , the first recess 51 includes a point-shaped recess, and a plurality of point-shaped recesses are randomly arranged on the second contact portion 12. This irregular design not only increases the air flow area between the device and the user's wrist 101, but also makes the wearing feel more natural and has higher fit.

[0061] In another embodiment, as shown in Figure 3 , 7 , the first recess 51 includes a strip-shaped recess, and a plurality of strip-shaped recesses are arranged in the length direction or the width direction of the second contact portion 12. The ordered design of the strip-shaped recess can realize air flow in each region.

[0062] As shown in Figure 8 , the second recess 61 includes a strip-shaped recess, and a plurality of strip-shaped recesses are arranged in the length direction of the wrist strap 3. Each second recess 61 extends in the width direction of the wrist strap 3. The strip-shaped recess at the wrist strap 3 can more effectively increase the air flow area between the wrist strap 3 and the user's wrist 101, promote the rapid evaporation of sweat, and reduce the feeling of dampness and discomfort when wearing.

[0063] As shown in Figure 7 , 8 , the height difference h1 between the lowest point of the first recess 51 and the highest point of the first protrusion 52 is 0.05cm-0.2cm;

[0064] And / or, the height difference h2 between the lowest point of the second recess 61 and the highest point of the second protrusion 62 is 0.05cm-0.2cm.

[0065] The height difference design of the present application not only ensures that the first protruding part 52 and the second protruding part 62 can effectively contact the user's wrist 101, providing sufficient support and stability, but also ensures that the first recessed part 51 and the second recessed part 61 can form a suitable air flow channel with the user's wrist 101, promoting air circulation and effectively reducing the stuffy feeling when worn.

[0066] As shown in Figure 2 , 3 , the area ratio of the first contact part 11 to the second contact part 12 is between 0.3 and 1.5.

[0067] Considering that the area of the first contact part 11 is much smaller than the area of the second contact part 12, it is difficult to ensure that the sensing device 2 is in contact with the user's wrist 101; while the area of the first contact part 11 is much larger than the area of the second contact part 12, although it can make the sensing device 2 better contact with the user's wrist 101, but it affects the air permeability and heat dissipation performance of the device, the present application sets the area ratio of the first contact part 11 to the second contact part 12 between 0.3 and 1.5, so that the wrist-worn electronic device of the present application can not only improve the detection accuracy in the wearing state, but also improve the comfort of the wearer.

[0068] The first contact part 11 and the second contact part 12 both include elastic contact parts, which improve the wearing comfort and adaptability of the device. The elastic contact part can deform moderately according to the shape and size of the user's wrist 101, realizing the close fit between the electronic device and the user's wrist 101, and at the same time reducing the compression feeling on the skin.

[0069] As shown in Figure 1 , the wrist strap 3 includes a first connecting strap 31 and a second connecting strap 32, and the first connecting strap 31 and the second connecting strap 32 are connected to the two ends of the main body 1 respectively; the first connecting strap 31 is provided with a plurality of clamping grooves 311, and the second connecting strap 32 is provided with a clamping piece 321, and the clamping piece 321 is switched on the plurality of clamping grooves 311, used for adjusting the tightness of the wrist strap 3; and / or, the first connecting strap 31 and the second connecting strap 32 include elastic connecting straps.

[0070] In one embodiment, the wrist strap 3 includes a first connecting strap 31 and a second connecting strap 32, and the first connecting strap 31 and the second connecting strap 32 are connected to the two ends of the main body 1 respectively; the first connecting strap 31 is provided with a plurality of clamping grooves 311, and the second connecting strap 32 is provided with a clamping piece 321, and the clamping piece 321 is switched on the plurality of clamping grooves 311, used for adjusting the tightness of the wrist strap 3. The present application adjusts the tightness of the wrist strap 3 according to the user's use demand through the cooperation of the clamping grooves 311 and the clamping piece 321, so that it can not only improve the detection accuracy in the wearing state, but also improve the comfort of the wearer.

[0071] In another embodiment, the wrist strap 3 comprises a first connecting strap 31 and a second connecting strap 32, which are respectively connected to the two ends of the main body 1; the first connecting strap 31 and the second connecting strap 32 comprise elastic connecting straps. The present application adjusts the tightness of the wrist strap 3 according to the use requirements of the user through the elastic connecting straps, so that it can not only improve the detection accuracy in the wearing state, but also improve the comfort of the wearer.

[0072] In other embodiments, the wrist strap 3 comprises a first connecting strap 31 and a second connecting strap 32, which are respectively connected to the two ends of the main body 1; the first connecting strap 31 is provided with a plurality of clamping grooves 311, and the second connecting strap 32 is provided with a clamping piece 321, which is switched on the plurality of clamping grooves 311 for adjusting the tightness of the wrist strap 3; the first connecting strap 31 and the second connecting strap 32 comprise elastic connecting straps. The present application adjusts the tightness of the wrist strap 3 according to the use requirements of the user through the cooperation of the clamping grooves 311 and the clamping piece 321, and at the same time, the first connecting strap 31 and the second connecting strap 32 adopt elastic connecting straps, which further strengthen the accuracy of the tightness adjustment, so that it can not only improve the detection accuracy in the wearing state, but also improve the comfort of the wearer.

[0073] As shown in Figure 2 , 3 , the main body 1 further comprises an arc-shaped transition part 13, one end of which is connected to the outer edge of the second contact part 12, and the other end extends towards the side of the main body 1 away from the user's wrist 101. The design of the arc-shaped transition part 13 not only makes the overall appearance of the device more smooth and beautiful, but also effectively disperses the pressure of the device on the edge of the user's wrist 101 when actually worn, reducing the discomfort that may be caused by long-term wearing. At the same time, it also increases the contact area between the device and the user's wrist 101, making the device more conformable and stable, improving the comfort and stability of wearing.

[0074] As shown in Figure 1 , 9 , the side wall of the main body 1 is provided with a knob 9, and the knob 9 is provided with anti-slip patterns 10. This design not only increases the friction between the finger and the knob 9, so that the user can easily grasp when adjusting or operating, and is not easy to slip, but also ensures that even in a humid or sweaty environment, the user can stably control the knob 9, improving the reliability of the product.
