Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0025] Please see Figure 1-5 A viewing distance adjustment mechanism for AR glasses includes a panoramic AR glasses body 1, a panoramic AR glasses protective shell 2 is provided on the outside of the panoramic AR glasses body 1, and an adjustment mechanism 3 is provided on the front side inside the panoramic AR glasses protective shell 2. The adjustment mechanism 3 includes a fixing component 301 and an adjustment component 302. The fixing component 301 is provided on the front and rear sides inside the panoramic AR glasses protective shell 2, and the adjustment component 302 is provided on the front side of the panoramic AR glasses protective shell 2.
[0026] The fixing component 301 includes a protective shell 3011, a limiting shell 3012, and a moving rod 3013. The protective shell 3011 is disposed on the front side inside the panoramic AR glasses body 1, the limiting shell 3012 is disposed inside the protective shell 3011, and the moving rod 3013 is disposed on the rear side inside the panoramic AR glasses body 1.
[0027] The adjustment assembly 302 includes a twist cap 3021, a rotating disk 3022, a fixing block 3023, and a limiting plate 3024. The twist cap 3021 is slidably connected to the front side of the panoramic AR glasses body 1. The rotating disk 3022 is rotatably connected to the inside of the protective shell 3011. The fixing block 3023 is rotatably connected to the right side of the rear side of the rotating disk 3022. The limiting plate 3024 is slidably connected to the inside of the protective shell 3011.
[0028] In this embodiment: by setting up a protective shell 3011, a limiting shell 3012, a moving rod 3013 in conjunction with a twist cap 3021, a rotating disk 3022, a fixing block 3023, and a limiting plate 3024, when using the viewing distance adjustment mechanism for AR glasses, the user can wear the panoramic AR glasses protective shell 2 in front of their eyes to facilitate the use of the panoramic AR glasses body 1 inside. Then, when it is necessary to adjust the viewing distance of the AR glasses, the user can rotate the twist cap 3021 to drive the rotating disk 3022 to rotate mechanically inside the limiting shell 3012, so that the rotating disk 3022 can drive the fixing block 3023 to perform circumferential motion. The fixed block 3023 moves within the special channel opened inside the limiting plate 3024, thereby driving the limiting plate 3024 to perform horizontal reciprocating motion. This motion is used to move the panoramic AR glasses body 1 under the support of the protective shell 3011 and the moving rod 3013. This allows the user to control the panoramic AR glasses body 1 by rotating the twist cap 3021. After the user adjusts it to the optimal viewing distance, the user can release the engagement between the twist cap 3021 and the rotating disk 3022 to prevent accidental contact with the twist cap 3021, which would change the optimal viewing distance and prevent the user from using the panoramic AR glasses body 1.
[0029] As a technical optimization of this utility model, the inner side of the limiting shell 3012 is movably connected to the outer side of the rotating disk 3022, and the outer side of the moving rod 3013 is slidably connected to the rear side of the panoramic AR glasses body 1.
[0030] In this embodiment, by setting the limiting shell 3012 and the moving rod 3013, the rotating disk 3022 and the panoramic AR glasses body 1 can be restricted, thereby increasing practicality.
[0031] As a technical optimization of this utility model, the front side of the panoramic AR glasses body 1 passes through the rear side of the protective shell 3011 and is slidably connected, and the front side of the panoramic AR glasses body 1 is fixedly connected to the right side of the limiting plate 3024.
[0032] In this embodiment, by setting the protective shell 3011 and the limiting plate 3024, the panoramic AR glasses body 1 can be conveniently limited and supported, thereby increasing its practicality.
[0033] As a technical optimization of this utility model, the front side of the rotating disk 3022 passes through the front side of the panoramic AR glasses protective shell 2 and is rotatably connected, and the front side of the rotating disk 3022 is fixedly connected to the limit block 4.
[0034] In this embodiment, by setting a rotating disk 3022 and a limiting block 4, the rotating disk 3022 can be easily controlled by twisting the cap 3021, thereby increasing its practicality.
[0035] As a technical optimization of this utility model, the rear side of the twist cap 3021 is slidably connected to the front side of the rotating disk 3022, and the inside of the twist cap 3021 is fixedly connected to the snap-fit outer shell 5, and the inner side of the snap-fit outer shell 5 is snapped with the limiting snap-fit block 4.
[0036] In this embodiment, by setting the snap-fit outer shell 5, it can be easily engaged with the limit block 4 to snap the twist cap 3021 at any time, thereby increasing its practicality.
[0037] As a technical optimization of this utility model, an elastic protective sleeve 6 is sleeved on the outer side of the twist cap 3021, and the outer side of the elastic protective sleeve 6 is provided with anti-slip texture.
[0038] In this embodiment, the elastic protective sleeve 6 makes it easier for users to use the twist cap 3021, thereby increasing its practicality.
[0039] As a technical optimization of this utility model, the limiting plate 3024 has a smooth channel 7 inside, and the inside of the smooth channel 7 is slidably connected to the outside of the fixing block 3023. The smooth channel 7 is arc-shaped.
[0040] In this embodiment, by setting a smooth channel 7, the fixing block 3023 can easily drive the limiting plate 3024 to reciprocate, thereby increasing practicality.
[0041] As a technical optimization of this utility model, the top and bottom of the limiting plate 3024 are fixedly connected to the limiting frame 8, and the inner side of the limiting frame 8 is rotatably connected to the auxiliary roller 9. The outer surface of the auxiliary roller 9 is in contact with the inner top and bottom surfaces of the protective shell 3011.
[0042] In this embodiment, by setting the limiting frame 8 and the auxiliary roller 9, the limiting plate 3024 can be moved inside the protective shell 3011, thereby increasing its practicality.
[0043] Working principle: First, when adjusting the panoramic AR glasses body 1, the user can wear the panoramic AR glasses protective case 2 in front of their eyes to allow them to use the panoramic AR glasses body 1 inside. Then, when adjusting the viewing distance of the AR glasses, the user can rotate the twist cap 3021 to drive the rotating disk 3022 to rotate mechanically inside the limiting shell 3012. This causes the rotating disk 3022 to drive the fixing block 3023 to perform circumferential motion, thereby causing the fixing block 3023 to move in a circular motion within the limiting plate 3024. The special channel moves internally, allowing the fixed block 3023 to drive the limiting plate 3024 to reciprocate horizontally. This movement is used to move the panoramic AR glasses body 1 under the support of the protective shell 3011 and the moving rod 3013, so that the user can control the panoramic AR glasses body 1 by rotating the twist cap 3021. After the user adjusts it to the optimal viewing distance, the user can release the engagement between the twist cap 3021 and the rotating disk 3022 to prevent accidental contact with the twist cap 3021, thereby changing the optimal viewing distance and hindering the user from using the panoramic AR glasses body 1.
[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the scope of the present utility model should be included within the protection scope of the present utility model.
