Further, the smart glasses further include an optical machine (not shown in the figure) arranged on the frame. The optical machine is used to emit a light beam to the lenses.

[0029] As shown in Figure 2 andFigure 3 As shown, specifically, the charging structure 100 includes a housing 10, a frame 20 and a charging terminal 30, the housing 10 is connected with the temple, the housing 10 is internally provided with a receiving space 11, the frame 20 is received in the receiving space 11, the charging terminal 30 is installed on the frame 20 and electrically connected with the main board, the charging terminal 30 is used for electrically connecting a charger to power the main board, the housing 10 is provided with a first mounting hole 12 for exposing the charging terminal 30, and an end of the charging terminal 30 away from the frame 20 is installed in the first mounting hole 12.

[0030] The charging structure 100 of the embodiment is accommodated in the receiving space 11 on the housing 10 by arranging the frame 20, so that the frame 20 is covered by the housing 10, which can avoid the frame 20 from being exposed outside the temple, so that the frame 20 can be prevented from being damaged and the frame 20 can be prevented from being exposed on the appearance surface of the smart glasses, thereby avoiding the product appearance of the smart glasses from being affected. Moreover, the end of the charging terminal 30 away from the frame 20 is installed in the first mounting hole 12 and does not protrude out of the first mounting hole 12, compared with arranging the charging terminal 30 to directly protrude and be exposed outside the temple, for example, protruding and being exposed outside the housing 10, the wear and accidental damage of the charging terminal 30 caused by directly contacting external objects can be reduced, and the risk of short circuit of the positive and negative poles of the charging terminal 30 caused by contacting sweat can also be reduced.

[0031] In combination Figure 1 In some embodiments, the housing 10 is arranged at the end of the temple away from the frame, which is more convenient for charging compared with arranging the housing 10 on the inner side of the temple.
