[0035] Please see Figures 1 to 8As shown, this utility model discloses a light-sensitive button anti-shake structure, mainly used in wearable devices, such as smartwatches. The light-sensitive button anti-shake structure includes a dial 10, a tube 20, a light sensor 30, a micro switch 40, and a button assembly 50. The dial 10 has a cavity 11 and a key hole 12 communicating with the cavity 11. The key hole 12 extends from the inner wall of the cavity 11 to the outer wall of the dial 10. The tube 20 is installed on the dial 10, with its middle part extending into the cavity 11. The middle part of the tube 20 has a limiting hole 21 communicating with the cavity 11. The light sensor 30 is used for electrical connection with the motherboard and is installed on the bottom wall of the inner side of the cavity 11. The micro switch 40 is used for electrical connection with the motherboard and is installed on the inner wall of the cavity 11.

[0036] The button assembly 50 includes a light-sensitive button 51, an elastic element 52, and a retaining ring 53. The outer wall of the light-sensitive button 51 is provided with a first annular groove 511, and the elastic element 52 is provided with a first through hole 521. One end of the light-sensitive button 51 is located outside the dial 10, and the other end of the light-sensitive button 51 passes through the first through hole 521, the key hole 12, and the limiting hole 21 in sequence and is correspondingly set with the micro switch 40. The first annular groove 511 communicates with the cavity 11. The retaining ring 53 is located in the cavity 11 and installed on the first annular groove 511. The retaining ring 53 abuts against the inner wall of the cavity 11. The retaining ring 53 is used to fix the light-sensitive button 51 and prevent the light-sensitive button 51 from falling out of the dial 10. The light-sensitive device 30 is set towards the light-sensitive button 51.

[0037] When the light-sensitive button 51 is rotated, the light-sensitive device 30 transmits the rotation signal of the light-sensitive button 51 to the motherboard, so as to select the function within the smartwatch. When the light-sensitive button 51 is pressed, the light-sensitive button 51 can activate the micro switch 40. The micro switch 40 transmits the activation signal to the motherboard, so as to confirm and exit the selected function. The anti-shake structure of the light-sensitive button uses the tube 20 to support the light-sensitive button 51 inside the dial 10, so that the light-sensitive button 51 is stable during rotation and the shaking effect is significantly improved. Users can quickly and accurately select the function within the smartwatch. The elastic element 52 can be a spring.

[0038] In this embodiment, the optical button anti-shake structure also includes two fasteners 60. The tube part 20 is formed by bending a metal sheet multiple times. The tube part 20 includes two first pieces 22 and two bent pieces 23 connected to the two first pieces 22 at both ends. The bent pieces 23 are located in the cavity 11.
