Description

Technical Field

[0001] This invention relates to the field of VR glasses technology, specifically to a VR glasses device. Background Technology

[0002] VR glasses (virtual reality glasses) are head-mounted devices that provide users with an immersive virtual reality experience through a high-resolution display and lens system. They feature head tracking technology and hand controllers, allowing users to move and interact freely in the virtual environment, while also being equipped with a stereo audio system to enhance spatial awareness. VR glasses are widely used in gaming, education, training, and entertainment, creating an immersive experience for users.

[0003] Currently, VR glasses are worn on the head, with the main body of the glasses close to the eyes. However, if the user is wearing glasses that are nearsighted, they need to remove them to wear the VR glasses because of their thickness. Removing the glasses may affect the user's viewing experience. Therefore, this does not meet the current needs, and we have proposed a new type of VR glasses. Summary of the Invention

[0004] This invention provides a VR headset that allows users to wear VR headsets while wearing prescription glasses. It addresses the issue mentioned in the background section where VR headsets are worn on the head, with the main body close to the eyes. When a user is wearing prescription glasses, the glasses need to be removed due to their thickness, which can negatively impact the viewing experience.

[0008] As an optional solution for VR glasses according to the present invention, the movable plate includes a first support plate, a second support plate, a third support plate and a fourth support plate disposed adjacent to the bottom side of the rotating screw. The first support plate and the second support plate are respectively provided with a first movable groove, and a first connecting rod is installed between the two first movable grooves. The third support plate and the fourth support plate are of the same specifications as the first support plate and the second support plate.

[0009] As an optional VR glasses solution according to the present invention, the third support plate and the second support plate are respectively provided with second movable slots, and a second connecting rod is installed between the two second movable slots. The first support plate and the fourth support plate have the same specifications as the third support plate and the second support plate.

[0010] As an optional solution for VR glasses according to the present invention, the surface of the first airbag is provided with a plurality of corrugated segments, and the plurality of corrugated segments are arranged in a rectangular row on the surface of the first airbag. A connecting seat is installed on the side of the first support plate and the second support plate. A docking rod is installed on the connecting seat. A docking groove is opened inside the sliding block. The docking groove is movably engaged with the docking rod. The bottom side of the connecting seat is set as an inclined surface. Inclined rods are symmetrically installed inside the VR glasses shell.

[0011] When the connecting seat moves, the tilting rod contacts the bottom side of the connecting seat and applies a pushing force to the connecting seat. At this time, the connecting seat moves upward and the docking rod engages above the docking groove.

[0012] As an alternative solution for VR glasses according to the present invention, the VR glasses housing is symmetrically equipped with slide rails, and the bottom sides of the fourth support plate and the third support plate are respectively equipped with sliders, which slide in cooperation with the slide rails.

[0013] As an alternative solution for VR glasses according to the present invention, wherein: a movable box is installed inside the VR glasses housing, electronic components are installed inside the movable box, a first bevel gear is installed on the rotating shaft of the knob, a support platform is installed on the inner wall of the VR glasses housing, a second bevel gear is installed on the side of the support platform, and the first bevel gear meshes with the second bevel gear.

[0014] As an optional solution for VR glasses according to the present invention, the surface of the movable box is provided with a rack segment, the rack segment meshes with the second bevel gear, the inside of the VR glasses housing is provided with a sliding groove, and a movable block is installed on the bottom side of the movable box, the movable block slidingly engaging inside the sliding groove;

[0015] When the knob is turned, the movable box moves by utilizing the cooperation of the first bevel gear, the second bevel gear, and the rack segment.

[0016] At this time, the moving block slides from one end of the groove to the other end.

[0017] As an alternative solution for VR glasses according to the present invention, a cylinder is installed on the inner wall of the VR glasses housing, a first gear is installed on the rotating shaft of the knob, an elastic strip is installed on the inner wall of the cylinder, and the end of the elastic strip is movably engaged with the first gear.

[0018] As an optional solution for VR glasses according to the present invention, a second airbag is installed inside the VR glasses housing, and a connecting pipe is provided in the inner wall of the VR glasses housing. A connecting pipe is installed at both ends of the connecting pipe, one of the connecting pipes is connected to the second airbag, and the other connecting pipe is connected to the first airbag. Therefore, the second airbag and the gas inside the first airbag are in communication.

[0019] When the movable box moves, it compresses the second airbag, so the gas inside the second airbag reaches the first airbag, and the first airbag expands.

[0020] The present invention has the following beneficial effects:

[0021] 1. In this VR glasses, during the rotation of the knob, the pulley assembly, rotating column, first bevel gear, second bevel gear and third bevel gear work together to make two rotating screws rotate. During the rotation of the two rotating screws, the sliding block on the surface of the rotating screws moves in opposite directions. With the cooperation of the connecting seat, docking groove and docking rod, the first support plate and the second support plate move in opposite directions. During the movement, the first airbag is pulled, causing the corrugated section of the first airbag to unfold, thereby expanding the coverage of the face. Therefore, it can be adapted to users who wear nearsighted glasses.

[0022] Furthermore, by moving the connecting seat closer to both sides of the VR glasses housing, the tilting rod contacts the bottom of the connecting seat, applying a pushing force to the connecting seat. At this time, the connecting seat moves upward, and the docking rod engages with the top of the docking groove. Simultaneously, the first support plate and the second support plate are lifted upward, thus expanding the length, width, and height of the first airbag. This allows users to wear VR glasses smoothly while wearing glasses, improving the usability of VR glasses.

[0023] 2. During the rotation of the knob, the VR glasses utilize the engagement of the first bevel gear, the second bevel gear, and the tooth segment to move the movable box closer to one side of the VR glasses housing. This creates a certain distance between the movable box containing the electronic components and the lenses of the nearsighted glasses, thus maintaining a suitable distance between the electronic components and the lenses of the nearsighted glasses. This improves focusing accuracy, allowing users to see a clear image and eliminate blurriness when wearing the VR glasses.

[0024] At the same time, through the cooperation of the elastic strip and the first gear, the knob can be restricted by the elastic strip when it stops rotating, which plays a role in positioning the knob and avoids the knob from rotating randomly, thus affecting the focusing problem.

[0025] 3. During the rotation of the knob, the first airbag of the VR glasses is activated by the cooperation of the moving component and the moving plate, causing the corrugated section of the first airbag to expand. As a result, the overall circumference and internal area of ​​the first airbag are also increased, thus reducing the possibility of the first airbag obstructing the lens of the nearsighted glasses. Furthermore, the cooperation of the first bevel gear, the second bevel gear, and the rack section causes the moving box to move closer to the second airbag and compress it. As a result, the second airbag is compressed, and the gas inside the second airbag reaches the first airbag through the cooperation of the connecting pipe and the connecting tube, causing the first airbag to expand. This makes it more comfortable for users who wear nearsighted glasses to wear the VR glasses. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: This example aims to address the issue that when users wear VR glasses, the glasses are placed on the head, with the main body of the glasses close to the eyes. If the user is wearing prescription glasses, they need to remove them because of their thickness. Removing the prescription glasses may affect the viewing experience. Please refer to [link to relevant documentation]. Figure 1 - Figure 9A VR headset includes a VR headset housing 110 and electronic components installed inside the VR headset housing 110. A first airbag 111 for conforming to a human face is installed on the VR headset housing 110. A moving plate 120 is installed on the VR headset housing 110. The first airbag 111 is installed on the side of the moving plate 120. A moving component 130 for expanding the circumference of the first airbag 111 is installed inside the VR headset housing 110. A knob 112 for controlling the movement of the moving component 130 is installed on the VR headset housing 110.

[0038] The moving component 130 includes a rotating column 131 mounted on the VR glasses housing 110, a first bevel gear 132 mounted on the rotating column 131, and a second bevel gear 133 and a third bevel gear 134 meshing with both sides of the first bevel gear 132.

[0039] The moving component 130 also includes rotating lead screws 135 symmetrically rotatably mounted inside the VR glasses housing 110. Sliding blocks 140 are slidably mounted on the surfaces of the two rotating lead screws 135. The two rotating lead screws 135 are respectively connected to the second bevel gear 133 and the third bevel gear 134. A pulley set 113 for transmission is installed between the rotating shaft of the knob 112 and the rotating column 131.

[0040] 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 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.

[0041] 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 disposed adjacent to the bottom side of the rotating lead screw 135. The first support plate 121 and the second support plate 122 are respectively provided with a first movable groove 150. 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.

[0042] The third support plate 123 and the second support plate 122 are respectively provided with second movable grooves 152, and a second connecting rod 153 is installed between the two second movable grooves 152. 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. The surface of the first airbag 111 is provided with a number of corrugated segments 160, and the number of corrugated segments 160 are arranged in a rectangular row on the surface of the first airbag 111.

[0043] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In specific implementation, the user rotates the knob 112. During the rotation of the knob 112, the pulley assembly 113 causes the rotating column 131 to rotate. During the rotation of the rotating column 131, the first bevel gear 132, which is coaxially arranged, rotates along with it. In the process of rotation, it drives the second bevel gear 133 and the third bevel gear 134 to rotate. During the rotation of the second bevel gear 133 and the third bevel gear 134, they respectively drive the two rotating screws 135 to rotate. During the rotation of the rotating screws 135, the sliding blocks 140 on the surface of the rotating screws 135 move to both sides of the VR glasses housing 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 pulled, causing the corrugated section 160 of the first airbag 111 to unfold, thereby expanding the coverage of the face, thus adapting to users who wear myopia glasses.

[0044] Connecting seats 161 are installed on the sides of the first support plate 121 and the second support plate 122. A docking rod 162 is installed on the connecting seat 161. A docking groove 163 is opened inside the sliding block 140. The docking groove 163 is movably engaged with the docking rod 162. The bottom side of the connecting seat 161 is set as an inclined surface. Inclined rods 164 are symmetrically installed inside the VR glasses housing 110. Slide rails 170 are symmetrically installed inside the VR glasses housing 110. Slider 171 is installed on the bottom side of the fourth support plate 124 and the third support plate 123 respectively. The slider 171 slides in cooperation with the slide rail 170.

[0045] See Figure 6 and Figure 7 Specifically, when the sliding block 140 moves the connecting seat 161, the connecting seat 161 moves closer to both sides of the VR glasses housing 110. The tilting rod 164 contacts the bottom side of the connecting seat 161 and applies a pushing force to the connecting seat 161. At this time, the connecting seat 161 moves upward, and the docking rod 162 engages 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 enlarged, so that the user can wear VR glasses smoothly while wearing myopia glasses.

[0046] In this embodiment: during the rotation of the knob 112, the two rotating screws 135 rotate through the cooperation of the pulley group 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. With the cooperation of the connecting seat 161, the docking groove 163 and the docking rod 162, the first support plate 121 and the second support plate 122 move in opposite directions. During the movement, the first airbag 111 is pulled, causing the corrugated section 160 of the first airbag 111 to unfold, thereby expanding the coverage of the face. Therefore, it can be adapted to users who wear myopia glasses.

[0047] Furthermore, by moving the connecting seat 161 closer to both sides of the VR glasses housing 110, the tilting rod 164 contacts the bottom side of the connecting seat 161 and applies a pushing force to the connecting seat 161. At this time, the connecting seat 161 moves upward, and the top of the docking rod 162 extends 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, thus expanding the length, width, and height of the first airbag 111. This allows users to wear VR glasses smoothly while wearing myopia glasses, improving the utilization rate of VR glasses.

[0048] Example 2 aims to address the issue that when users wearing nearsighted glasses wear VR glasses, the user's focus is concentrated on the lenses of their glasses, causing the focal distance to be too close to the VR glasses lenses, thus affecting usability. This example is an improvement upon Example 1. For details, please refer to [link to example]. Figures 1-9 ,

[0049] The VR glasses housing 110 has a movable box 180 installed inside, and electronic components are installed inside the movable 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 housing 110, and a second bevel gear 183 is installed on the side of the support platform 182. The first bevel gear 181 and the second bevel gear 183 mesh.

[0050] The surface of the mobile box 180 is provided with a rack segment 184, which meshes with the second bevel gear 183. The VR glasses housing 110 is provided with a sliding groove 190. A moving block 191 is installed on the bottom side of the mobile box 180, and the moving block 191 slides in the sliding groove 190.

[0051] When the knob 112 is turned, the movable box 180 moves by utilizing the cooperation of the first bevel gear 181, the second bevel gear 183 and the rack segment 184.

[0052] At this time, the moving block 191 slides from one end of the slide 190 to the other end.

[0053] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In practice, when the user rotates the knob 112, it drives the coaxially arranged first bevel gear 181 to rotate, which in turn drives the second bevel gear 183 to rotate. As the second bevel gear 183 rotates, it uses the rack segment 184 to move the movable box 180 closer to one side of the VR glasses housing 110. This creates a certain distance between the movable box 180, which contains the electronic components, and the lenses of the glasses. By moving the movable box 180, a suitable distance is maintained between the electronic components and the lenses of the glasses, thereby improving the accuracy of focusing. When wearing VR glasses, the user can see a clear picture and eliminate blurriness.

[0054] 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 the end of the elastic strip 212 is engaged with the first gear 211.

[0055] It should be noted that the elastic strip 212 can be set as a metal spring or a plastic spring.

[0056] See Figure 5 In practice, as the user rotates the knob 112, the first gear 211, which is coaxially mounted on the knob 112, rotates accordingly, causing the unfolded elastic strip 212 to be compressed and tightened. Therefore, the knob 112 can rotate smoothly. When the user has adjusted it to 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 engages with the teeth of the first gear 211, thereby restricting the first gear 211 and reducing unnecessary shaking of the knob 112.

[0057] In this embodiment: During the rotation of knob 112, the first bevel gear 181, the second bevel gear 183 and the tooth segment are used to move the movable box 180 closer to one side of the VR glasses housing 110. This creates a certain distance between the movable box 180, which contains electronic components, and the lens of the myopia glasses. This achieves a suitable distance between the electronic components and the lens of the myopia glasses, thereby improving the accuracy of focusing and allowing the user to see a clear picture when wearing VR glasses, eliminating blurriness.

[0058] Meanwhile, through the cooperation of the elastic strip 212 and the first gear 211, the knob 112 can be restricted by the elastic strip 212 when it stops rotating, thus positioning the knob 112 and preventing the knob 112 from rotating arbitrarily, which would affect the focusing.

[0059] Example 3 aims to address the issue that when the first airbag 111 is deployed at the corrugated section 160 due to the cooperation of the moving component 130 and the moving plate 120, although the circumference of the first airbag 111 increases, it also means that the gas inside the first airbag 111 is insufficient, affecting its wearability. This example is an improvement on Example 2. For details, please refer to Example 2. Figures 1-9 The VR glasses housing 110 has a second airbag 220 installed inside. A connecting pipe 221 is provided in the inner wall of the VR glasses housing 110. A connecting pipe 222 is installed at both ends of the connecting pipe 221. One connecting pipe 222 is connected to the second airbag 220, and the other connecting pipe 222 is connected to the first airbag 111. Therefore, the second airbag 220 and the first airbag 111 are connected in terms of gas.

[0060] When the moving box 180 moves, it compresses the second airbag 220, so the gas inside the second airbag 220 reaches the first airbag 111 and the first airbag 111 expands.

[0061] See Figure 2 and Figure 3 In specific implementation, when the user manually rotates the knob 112, the first airbag 111 is engaged by the moving component 130 and the moving plate 120, causing the corrugated section 160 of the first airbag 111 to expand. At the same time, the moving box 180 is engaged by the first bevel gear 181, the second bevel gear 183 and the rack section 184, causing one side of the moving box 180 to move closer to the second airbag 220 and compress it. The gas inside the compressed second airbag 220 reaches the first airbag 111 through the connection pipe 221 and the connecting pipe 222. Therefore, the first airbag 111 expands, making it more comfortable for users wearing myopia glasses to use VR glasses. Moreover, due to the expansion of the first airbag 111, there is a certain distance between the first airbag 111 and the myopia glasses lens, reducing the possibility of obstructing the myopia glasses lens.

[0062] In this embodiment: During the rotation of knob 112, the first airbag 111 is affected by the cooperation of moving component 130 and moving plate 120, causing the corrugated section 160 of the first airbag 111 to expand. Therefore, the overall circumference and internal area of ​​the first airbag 111 are also increased, thus reducing the possibility of the first airbag 111 obstructing the lens of the myopia glasses. Moreover, by utilizing the cooperation of the first bevel gear 181, the second bevel gear 183 and the rack section 184, the moving box 180 moves closer to the second airbag 220 and compresses it. Therefore, the second airbag 220 is compressed, and the gas inside the second airbag 220 reaches the inside of the first airbag 111 through the cooperation of connecting pipe 221 and connecting pipe 222, causing the first airbag 111 to expand, making it more comfortable for users wearing myopia glasses to wear VR glasses.

[0063] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0064] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
