For the sake of convenience, only the parts related to the present invention are shown in the figure.

[0031] It should be noted that the directional indications involved in the present invention (such as up, down, front, back, etc.) are only used to explain the relative positional relationship between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly; if the descriptions of "first", "second", etc. involved in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0032] Depend on Figures 1 to 4It can be seen that the mask of the embodiment of the present invention includes a ring-shaped mask bracket, and a nose avoidance portion 20 is provided at the lower side of the mask bracket. The mask bracket includes a head-mounted connection portion arranged on a side away from the user's face, and a face-fitting portion arranged on a side facing the user's face. The face-fitting portion is installed on the head-mounted connection portion, and a hollow area is formed between the face-fitting portion and the head-mounted connection portion. The face-fitting portion is a contoured structure adapted to the user's face; it also includes a shading structure arranged along the extension direction of the mask bracket, which is used to shade the area enclosed by the mask bracket.

[0033] During installation, the head-mounted connection part of the mask bracket is fixedly connected to the host of the head-mounted device, and the lens barrel assembly of the host is located inside the area surrounded by the mask bracket. When the head-mounted device is worn, the face fitting part is used to fit the user's face; since the face fitting part is installed on the head-mounted connection part, and a hollow area is formed between the face fitting part and the head-mounted connection part, the face bracket forms a frame structure, and a shading structure is provided on the mask bracket along the extension direction of the mask bracket, which can shade the area surrounded by the mask bracket. While ensuring the shading effect, the weight of the mask can be effectively reduced, which solves the problem of heavy mask weight of existing head-mounted devices, reduces the weight of the head-mounted device, and can improve the wearing experience.

[0034] In an embodiment of the present invention, the mask bracket includes a left frame 10a and a right frame 10b which are spaced apart, and a nose avoidance portion 20 is formed between the lower side of the left frame 10a and the lower side of the right frame 10b; the left frame 10a and the right frame 10b respectively include an arc-shaped mounting plate 11 and an arc-shaped support plate 12, and the two end portions of the support plate 12 are fixedly connected to the end portions on the corresponding sides of the mounting plate 11, and a spacing is provided between the arc top of the support plate 12 and the arc top of the mounting plate 11; the two connecting portions between the mounting plate 11 and the support plate 12 of the left frame 10a and the two connecting portions between the mounting plate 11 and the support plate 12 of the right frame 10b are adjacent to each other, and the support plates 12 of the left frame 10a and the support plates 12 of the right frame 10b jointly form a face fitting portion facing the user's face, and the mounting plate 11 of the left frame 10a and the mounting plate 11 of the right frame 10b jointly form a head-mounted connection portion.

[0035] Specifically, the left frame 10a is set to correspond to the left side of the user's face, and the right frame 10b is set to correspond to the right side of the user's face. That is, the shape of the mounting plate 11 of the left frame 10a is adapted to the shape of the surrounding part on the left side of the host facing the user's face, and the shape of the support plate 12 of the left frame 10a is adapted to the left side of the user's face. The shape of the mounting plate 11 of the right frame 10b is adapted to the shape of the surrounding part on the right side of the host facing the user's face, and the shape of the support plate 12 of the right frame 10b is adapted to the right side of the user's face.
