[0033] The utility model provides an electronic watch.

[0034] See also Figure 1 and Figure 2 In one embodiment of the utility model, the electronic watch includes a bottom shell 100, a structured light sensor 200 and a silicone suction cup 300. The bottom shell 100 is formed with a receiving space 11. The structured light sensor 200 is arranged in the receiving space 11 and exposed on the outer wall of the bottom shell 100. The silicone suction cup 300 is arranged on the outer wall of the bottom shell 100, including a negative pressure cover 31 arranged around the structured light sensor 200. The negative pressure cover 31 can be elastically deformed and has a negative pressure space 311. When the structured light sensor is required, the negative pressure cover 31 is provided with a negative pressure space 311. When the sensor 200 detects the user's heart rate, the user can press down the bottom shell 100 to cause the negative pressure cover 31 to undergo elastic deformation, so as to discharge the gas in the negative pressure space 311, so that the wrist skin and the structured light sensor 200 are close to each other under the action of negative pressure. The shading structure 32 can prevent external light from entering between the structured light sensor 200 and the skin, so that when the light emitted by the structured light sensor 200 is irradiated into the negative pressure space 311, the influence of external light on the structured light sensor 200 is effectively reduced.

[0035] In one embodiment, the shading structure 32 includes a shading tube 321 , the bottom of the negative pressure cover 31 is connected to the shading tube 321 , and the shading tube 321 is communicated with the negative pressure space 311 , and the shading tube 321 is arranged circumferentially around the structured light sensor 200 . The light emitted by the structured light sensor 200 enters the negative pressure space 311 after passing through the light shielding tube 321, wherein, when the negative pressure cover 31 is deformed by external force and discharges the air between the structured light sensor 200 and the wrist skin, the wrist skin is tightly attached to the inner wall of the negative pressure cover 31 under the action of negative pressure, so as to prevent external light from entering the negative pressure space 311 from the negative pressure cover 31. The light shielding tube 321 can effectively prevent external light from entering between the structured light sensor 200 and the wrist. At the same time, the light shielding tube 321 helps to increase the discharged gas to enhance the negative pressure suction between the negative pressure cover 31 and the wrist skin, which can effectively prolong the time of negative pressure suction between the structured light sensor 200 and the wrist skin. After wearing the electronic watch for a long time, the debris metabolized by the wrist skin accumulates on the structured light sensor 200. The dirt formed is not easy to clean and will interfere with the detection accuracy of the structured light sensor 200. The light shielding tube 321 can also avoid a large area of ​​direct contact between the wrist skin and the structured light sensor 200. The dirt metabolized by the wrist skin is easy to clean and the detection of the structured light sensor 200 is prevented from being interfered with by the dirt.

[0036] In one embodiment, the light shielding tube 321 is made of opaque soft rubber. At this time, external light cannot penetrate into the light shielding tube 321 and interfere with the structured light sensor 200 in the light shielding tube 321. In other embodiments, the inner wall of the light-transmitting tube may be provided with a light shielding layer.

[0037] In one embodiment, the negative pressure cover 31 is made of opaque soft rubber. This helps to further prevent external light from entering the negative pressure space 311 to interfere with the structured light sensor 200. And when the negative pressure cover 31 and the light shielding tube 321 are both made of opaque soft rubber, there is no need to press down the case to elastically deform the negative pressure cover 31, and the silicone suction cup 300 with a light shielding function can prevent light from entering the negative pressure space 311. Furthermore, the negative pressure cover 31 and the light shielding tube 321 are integrally formed. In other embodiments, a light shielding layer may also be provided on the inner side of the negative pressure cover 31.

[0038] In another embodiment, the silicone suction cup 300 further includes a light-transmitting sheet 33, a mounting countersunk hole 12 is provided on the outer wall surface of the bottom shell 100, the structured light sensor 200 is provided in the mounting countersunk hole 12, and the light-transmitting sheet 33 is covered in the mounting countersunk hole 12. At this time, whenever the negative pressure cover 31 undergoes elastic deformation, the wrist skin is adsorbed by the light-transmitting sheet 33, and the light emitted by the structured light sensor 200 passes through the light-transmitting sheet 33 and irradiates the wrist skin. The light-transmitting sheet 33 can protect the structured light sensor 200. After wearing the electronic watch for a long time, the debris metabolized on the wrist skin is stacked on the structured light sensor 200, and the dirt formed is not easy to clean and will interfere with the detection accuracy of the structured light sensor 200. The provision of the light-transmitting sheet 33 can avoid direct contact between the wrist skin and the structured light sensor 200, and the dirt accumulated on the light-transmitting sheet 33 is easy to clean.

[0039] In another embodiment, the light-transmitting sheet 33 includes a connecting portion 331 and a plug-in portion 332, wherein the plug-in portion 332 is disposed in the mounting countersunk hole 12, the connecting portion 331 extends out of the mounting countersunk hole 12, the negative pressure cover 31 is disposed around the outer circumference of the connecting portion 331, and the outer wall surface of the negative pressure cover 31 abuts against the bottom shell 100. At this time, the negative pressure cover 31 is disposed circumferentially around the mounting countersunk hole 12, that is, the bottom of the negative pressure cover 31 has more structures capable of elastic deformation, which helps to prolong the time when negative pressure suction exists between the negative pressure cover 31 and the wrist skin, so that the structured light sensor 200 has sufficient time to detect the user, and the light shielding structure 32 is disposed around the mounting countersunk hole 12 to prevent external light from irradiating into the negative pressure space 311 through the outer circumference of the connecting portion 331, thereby interfering with the detection of the structured light sensor 200. In other embodiments, the negative pressure cover 31 can also be disposed on the outer wall surface of the bottom shell 100.

[0040] In one embodiment, the light shielding structure 32 and the negative pressure cover 31 are configured as the same structure, and the material of the negative pressure cover 31 is configured as opaque soft rubber to prevent external light from entering the light-transmitting sheet 33 from the side of the connecting portion 331 and interfering with the light emitted by the structured light sensor 200. Furthermore, the material of the light-transmitting sheet 33 is configured as a transparent hard plastic, and the negative pressure cover 31 and the light-transmitting sheet 33 are integrally formed, which helps to extend the service life of the silicone suction cup 300. In other embodiments, the light shielding structure 32 may include a light shielding layer, which is provided on the outer side wall of the negative pressure cover 31, or the light shielding structure 32 may include a light shielding layer, which is provided on the outer side surface of the connecting portion 331.

[0041] In another embodiment, the cross-sectional shape of the bottom shell 100 is configured as a circle. Usually, the cross-sectional area of ​​the silicone suction cup 300 is also a circle. When the shape of the bottom shell 100 is similar to the shape of the silicone suction cup 300, it helps to make the shape of the electronic watch more beautiful. At the same time, when the user presses down the bottom shell 100 to exert pressure on the negative pressure cover 31 and elastically deforms the negative pressure cover 31, the bottom shell 100 with a circular cross-section can exert uniform pressure on the negative pressure cover 31, which helps to improve the exhaust rate of air in the negative pressure space 311. In other embodiments, the cross-sectional shape of the bottom shell 100 can also be configured as a square or a random shape.

[0042] In another embodiment, the maximum diameter of the cross section of the negative pressure cover 31 is smaller than the maximum diameter of the cross section of the bottom case 100. That is, when the user wears the electronic watch, the presence of the silicone suction cup 300 is not easily noticed, which contributes to the beauty of the electronic watch. In other embodiments, the maximum diameter of the cross section of the negative pressure cover 31 may be greater than or equal to the maximum diameter of the cross section of the bottom case 100.

[0043] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
