In the embodiment, when the arm 200 rotates, referring to fig. 12, only the area a in the two FPC sections 420 is bent to a certain extent along with the arm 200, and the bending radius is large, and the U-shaped accommodating cavity 370 provides a large movement space for the two FPC sections 420 without pressing contact, so that the two FPC sections 420 are prevented from being damaged in the bending process, and the reliability of the FPC assembly 400 is improved. When temple 200 is folded inward, FPC section 420 extends from P1 to P2; when temple 200 is unfolded, FPC section 420 extends from P1 to P3.
In this embodiment, referring to fig. 6, the deformation limiting portion 333 is a plate-shaped structure, and the plate-shaped deformation limiting portion 333 shields the upper and lower sides of the U-shaped accommodating cavity 370, so as to limit the FPC assembly 400 (specifically, the extension section 422) in the U-shaped accommodating cavity 370, and prevent the extension section 422 from coming off from the U-shaped accommodating cavity 370.
Referring to fig. 14, when the wire harness 500 formed by other circuits is routed, the routing path of the wire harness 500 is the same as that of the FPC assembly 400, the wire harness 500 is also inserted into the first cavity 110, the U-shaped accommodating cavity 370 of the rotation shaft 300, and the second cavity 210, and the temple 200 can prevent the wire harness 500 from being exposed when folded.
