[0030] The moving assembly 130 also includes a rotating screw rod 135 symmetrically mounted inside the VR glasses housing 110, and sliding blocks 140 are slidably mounted on the surfaces of the two rotating screw rods 135. The two rotating screw rods 135 are respectively connected to the second bevel gear 133 and the third bevel gear 134, and a pulley group 113 for transmission is installed between the rotating shaft of the knob 112 and the rotating column 131.

[0031] It should be noted that the pulley assembly 113 is usually composed of a belt and a pulley assembly 113, and is used for transmission between the rotating shafts. Since the pulley assembly 113 is a mature existing technology, its specific model, working principle and usage are well known to those skilled in the art and will not be elaborated here.

[0032] The movable plate 120 includes a first support plate 121, a second support plate 122, a third support plate 123 and a fourth support plate 124 which are arranged adjacent to the bottom side of the rotating screw rod 135. The first support plate 121 and the second support plate 122 are respectively provided with a first movable groove 150, and a first connecting rod 151 is installed between the two first movable grooves 150. The third support plate 123 and the fourth support plate 124 have the same specifications as the first support plate 121 and the second support plate 122.

The first support plate 121 and the fourth support plate 124 have the same specifications as the third support plate 123 and the second support plate 122. A plurality of corrugated sections 160 are arranged on the surface of the first airbag 111, and the plurality of corrugated sections 160 are arranged in a rectangular shape on the surface of the first airbag 111.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In a specific implementation, the user rotates the knob 112, so that during the rotation of the knob 112, the cooperation of the pulley set 113 is used to make the rotating column 131 rotate. During the rotation of the rotating column 131, the coaxially arranged first bevel gear 132 follows the rotation, and drives the second bevel gear 133 and the third bevel gear 134 to rotate during the rotation. During the rotation of the second bevel gear 133 and the third bevel gear 134, the two rotating screws 135 are respectively driven to rotate. During the rotation of the rotating screw 135, the sliding block 140 on the surface of the rotating screw 135 moves toward the two sides of the VR glasses shell 110. During the movement, the two sliding blocks 140 respectively drive the first support plate 121 and the second support plate 122 to move. Therefore, during the opposite movement of the first support plate 121 and the second support plate 122, the first airbag 111 is involved, so that the corrugated section 160 of the first airbag 111 is unfolded, thereby expanding the wrapping of the face, so that it can adapt to users wearing myopic glasses.

[0035] A connecting seat 161 is installed on the side of the first support plate 121 and the second support plate 122, and a docking rod 162 is installed on the connecting seat 161. A docking groove 163 is opened inside the sliding block 140, and the docking groove 163 is movably engaged with the docking rod 162.

[0036] See Figure 6 and Figure 7 In a specific implementation, when the sliding block 140 drives the connecting seat 161 to move, the connecting seat 161 approaches the two sides of the VR glasses shell 110, and the tilting rod 164 contacts the bottom side of the connecting seat 161 and applies a top force to the connecting seat 161. At this time, the connecting seat 161 moves up, and the docking rod 162 is engaged with the top of the docking groove 163. At the same time, the first support plate 121 and the second support plate 122 are lifted upward, so the length, width and height of the first airbag 111 are expanded, so that the user can wear VR glasses smoothly while wearing myopia glasses.

[0037] In this embodiment: during the rotation of the knob 112, the two rotating screws 135 are rotated by the cooperation of the pulley set 113, the rotating column 131, the first bevel gear 132, the second bevel gear 133 and the third bevel gear 134. During the rotation of the two rotating screws 135, the sliding block 140 on the surface of the rotating screw 135 moves in the opposite direction, and the first support plate 121 and the second support plate 122 are moved in opposite directions by the cooperation of the connecting seat 161, the docking groove 163 and the docking rod 162. During the movement, the first airbag 111 is pulled so that the corrugated section 160 of the first airbag 111 is unfolded, thereby expanding the wrapping of the face, so that it can adapt to users wearing myopic glasses; Moreover, by approaching the two sides of the VR glasses shell 110 through the connecting seat 161, the tilting rod 164 contacts the bottom side of the connecting seat 161 and applies a top force to the connecting seat 161. At this time, the connecting seat 161 moves up, and the top of the docking rod 162 penetrates into the highest point of the docking groove 163. At the same time, the first support plate 121 and the second support plate 122 are lifted upward, so the length, width and height of the first airbag 111 are expanded, so that the user can wear VR glasses smoothly while wearing myopia glasses, thereby improving the utilization rate of VR glasses.

[0038] Embodiment 2: This embodiment is intended to help solve the problem that when a user wearing myopia glasses wears VR glasses, the user focuses on the lenses of the myopia glasses, which causes the focal distance to be too close to the lenses of the VR glasses, affecting the use. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 9 , A mobile box 180 is installed inside the VR glasses shell 110, and electronic components are installed inside the mobile box 180. A first bevel gear 181 is installed on the rotating shaft of the knob 112. A support platform 182 is installed on the inner wall of the VR glasses shell 110. A second bevel gear 183 is installed on the side of the support platform 182. The first bevel gear 181 is meshed with the second bevel gear 183.

[0039] A rack segment 184 is provided on the surface of the moving box 180, and the rack segment 184 meshes with the second bevel gear 183. A slide groove 190 is provided inside the VR glasses housing 110, and a moving block 191 is installed on the bottom side of the moving box 180, and the moving block 191 is slidably fitted inside the slide groove 190; When the knob 112 is turned, the first bevel gear 181, the second bevel gear 183 and the rack segment 184 cooperate to move the moving box 180; At this time, the moving block 191 slides from one end of the sliding groove 190 to the other end.

[0040] See Figure 1 , Figure 2, Figure 3 , Figure 4 and Figure 5 In a specific implementation, when the user rotates the knob 112, the coaxially arranged first bevel gear 181 is driven to rotate, so that the rotation of the first bevel gear 181 drives the second bevel gear 183 to rotate. Therefore, during the rotation of the second bevel gear 183, the cooperation of the rack segment 184 is utilized to make the mobile box 180 approach one side of the VR glasses housing 110, so that there is a certain distance between the mobile box 180 on which the electronic components are installed and the lenses of the myopia glasses. By moving the mobile box 180, a suitable distance is maintained between the electronic components and the lenses of the myopia glasses, thereby improving the focusing accuracy, and the user can see a clear picture when wearing the VR glasses, eliminating the blur.

[0041] A cylinder 210 is installed on the inner wall of the VR glasses housing 110 , a first gear 211 is installed on the rotating shaft of the knob 112 , an elastic strip 212 is installed on the inner wall of the cylinder 210 , and an end of the elastic strip 212 is movably engaged with the first gear 211 .

[0042] It should be noted that the elastic strip 212 can be configured as a metal spring sheet or a plastic spring sheet.

[0043] See Figure 5 In a specific implementation, when the user rotates the knob 112, the first gear 211 coaxially arranged with the knob 112 rotates accordingly, so that the unfolded elastic strip 212 is pressurized and tightened, so that the knob 112 can rotate smoothly. When the user adjusts a certain range, the knob 112 stops rotating. At this time, the tightened elastic strip 212 unfolds, and the end of the elastic strip 212 is engaged with the teeth of the first gear 211, so that the first gear 211 is restricted and the unnecessary shaking of the knob 112 is reduced.

[0044] In this embodiment: during the rotation of the knob 112, the first bevel gear 181, the second bevel gear 183 and the tooth segment cooperate to make the mobile box 180 approach one side of the VR glasses housing 110, so that there is a certain distance between the mobile box 180 with the electronic components installed and the lenses of the myopia glasses, so that the electronic components and the lenses of the myopia glasses maintain a suitable distance, thereby improving the focus accuracy, so that the user can see a clear picture when wearing the VR glasses, eliminating the blur; At the same time, through the cooperation between the elastic strip 212 and the first gear 211, when the knob 112 stops rotating, it can be restricted by the elastic strip 212, thereby positioning the knob 112 and avoiding the problem of the knob 112 rotating at will and affecting the focus as much as possible.

[0045] Embodiment 3: This embodiment is intended to promote the solution of the problem that when the first airbag 111 is deployed at the corrugated section 160 by the cooperation of the moving assembly 130 and the moving plate 120, although the first airbag 111 is enlarged in circumference, it also means that there is insufficient gas inside the first airbag 111, which affects the wearing. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 9 A second airbag 220 is installed inside the VR glasses housing 110, a connecting pipe 221 is opened in the inner wall of the VR glasses housing 110, and connecting pipes 222 are installed at both ends of the connecting pipe 221, one of the connecting pipes 222 is connected to the second airbag 220, and the other connecting pipe 222 is connected to the first airbag 111, so that the second airbag 220 is in communication with the internal gas of the first airbag 111; When the moving box 180 moves, the second airbag 220 is squeezed, so that the gas inside the second airbag 220 reaches the inside of the first airbag 111, and the first airbag 111 expands.

[0046] See Figure 2 and Figure 3 In a specific implementation, when the user manually rotates the knob 112, the first airbag 111 is cooperated with the moving assembly 130 and the moving plate 120, so that the first airbag 111 is unfolded at the corrugated section 160. At the same time, the moving box 180 is cooperated with the first bevel gear 181, the second bevel gear 183 and the rack section 184, so that one side of the moving box 180 approaches the second airbag 220 and squeezes it. The gas inside the squeezed second airbag 220 reaches the inside of the first airbag 111 through the cooperation of the connecting pipe 221 and the connecting pipe 222. Therefore, the first airbag 111 expands, allowing users wearing myopia glasses to use VR glasses more comfortably. Moreover, due to the expansion of the first airbag 111, there is a certain distance between the first airbag 111 and the glass lens of the myopia glasses, reducing the possibility of blocking the glass lens of the myopia glasses.

[0047] In this embodiment: during the rotation of the knob 112, the first airbag 111 is cooperated with the moving component 130 and the moving plate 120, so that the first airbag 111 is unfolded at the corrugated section 160, so the overall circumference and internal area of ​​the first airbag 111 are also expanded, thereby reducing the possibility of the first airbag 111 blocking the glass of the myopic glasses; not only that, by utilizing the cooperation of the first bevel gear 181, the second bevel gear 183 and the rack section 184, the moving box 180 is moved close to the second airbag 220 and squeezed, so that the second airbag 220 is squeezed, so that the gas inside the second airbag 220 reaches the inside of the first airbag 111 through the cooperation of the connecting pipe 221 and the connecting pipe 222, so that the first airbag 111 expands, allowing users wearing myopic glasses to wear VR glasses more comfortably.
