The number of lenses 300 may be one or two, for example, the frame 100 is only equipped with one lens 300, and when worn, the lens 300 spans the left eye and right eye of the user. Of course, the frame 100 may also be equipped with only one lens 300, and the lens 300 only corresponds to the left eye or right eye of the user, and is used as a monocular. For another example, two lenses 300 are mounted on the frame 100, and the two lenses 300 correspond one to one with the left eye and right eye of the user. Among them, the near-eye side 101 of the frame 100 refers to the side of the frame 100 facing the human eye when the wearable device 10 is in a wearing state.

[0031] In some embodiments, the near-eye display device 200 may be detachably connected to the frame 100 by magnetic attraction, for example, magnets are respectively fixed to the near-eye display device 200 and the frame 100, and the connection is made by the attraction between the magnets. In some other embodiments, the near-eye display device 200 may also be connected to the frame 100 by a snap-fit ​​structure.

[0032] In some embodiments, the installation area 102 may be a groove, or may be an area flush with the surface of the frame 100 . In some other embodiments, the installation area 102 may also be a raised area on the surface of the frame 100 .

[0033] In some embodiments, the mounting area 102 is a groove, the first conductive member 140 is a contact point, the second conductive member 230 is a spring pin, and the sealing assembly 500 is disposed around the second conductive member 230 .

[0037] In some embodiments, the seal 520 and the boss 521 are made of plastic, silicone or soft rubber material, and the strength of the seal 520 and the boss 521 is less than the strength of the substrate 510. The seal 520 and the boss 521 can be made of plastic or silicone material with elastic deformation ability, and the substrate 510 can be made of plastic or metal alloy material with certain strength. It can be understood that the seal 520 and the boss 521 are made of materials that prevent penetration, leakage and erosion.

[0038] The seal 520 and the boss 521 may be an integral structure. Specifically, the seal 520 and the boss 521 may be integrally injection molded. The engagement of the boss 521 with the second groove 1023 may effectively improve the waterproof effect of the sealing assembly 500.
