Description

[0001] This invention is a divisional application of the patent with application number 2024113050765, application date September 19, 2024, and invention name “A kind of anti-bump VR glasses”. Technical Field

[0002] The present invention relates to the technical field of VR glasses, and in particular to a pair of anti-collision VR glasses. Background Art

[0003] VR glasses, or virtual reality glasses, are devices that provide an immersive experience by simulating a virtual environment. They are usually composed of one or more display screens, sensors, lenses and other hardware components. When users wear these glasses, they can feel the immersive feeling of being in the virtual world through multiple senses such as vision, hearing and touch.

[0004] At present, VR glasses are widely used in entertainment, education, training, medical and other fields, bringing more innovative application scenarios and experiences. Anti-collision of VR glasses is an important aspect of the design, because users may lose perception of the surrounding environment due to immersion during use. When the built-in sensors and cameras detect that the user is approaching surrounding objects, the system can issue a warning or automatically adjust the virtual environment to reduce the risk of collision, or when the user approaches the set virtual safety area boundary, the system will remind the user to avoid collision. These measures combined can significantly reduce the risk of collision during the use of VR glasses and enhance user safety.

[0005] At present, when users who wear myopia glasses use VR glasses, the myopia glasses are easily bumped against the lenses of the VR glasses, causing wear of the lenses of the VR glasses. Annular gaskets are usually used to block the VR lenses and myopia glasses. However, users are required to purchase annular gaskets separately and assemble them on the existing VR glasses, which makes it inconvenient to protect the lenses of the VR glasses. Therefore, it does not meet the existing needs. In this regard, we propose a pair of anti-bump VR glasses. Summary of the invention

The anti-collision VR glasses, the inflatable component fills air into the lifting airbag through the air pipe, so that the lifting airbag expands outward and increases in height until the upper surface of the lifting airbag is higher than the upper surface of the lens, so that when the user wearing myopia glasses uses the glasses body, the lifting airbag blocks the myopia glasses and the lens, thereby facilitating the protection of the lens, and solving the problem that the myopia glasses are easy to collide with the lenses of the VR glasses when the user wearing myopia glasses uses the VR glasses, causing the lenses of the VR glasses to be worn.

[0018] 2. For the anti-collision VR glasses, after the lifting airbag is inflated and unfolded, the inflation assembly continues to inflate, so that the unfolding area of ​​the folds of the outer ring of the wrapped airbag increases, while the area of ​​the smooth surface of the inner ring of the wrapped airbag remains unchanged, so that the wrapped airbag extends inward at its upper end opening, so that the upper end opening of the wrapped airbag is reduced, the lens is wrapped inside as much as possible, and the area of ​​the lens exposed to the outside is reduced as much as possible, so that it is not easy to collide with debris.

[0019] 3. The anti-collision VR glasses, when the first knob is turned, the turntable drives the first piston and the second piston to rotate in the housing, and then the second wedge block on the first piston conflicts with the first wedge block, the first spring is compressed, so that the first piston is blocked and stationary, and the second piston that continues to rotate sucks the outside air into the housing through the first one-way valve; Subsequently, the second piston passes over the air inlet end of the second one-way valve. At the same time, the first spring is compressed to the maximum extent, causing the first piston to start to rotate, thereby compressing the second spring through the cooperation of the first wedge block and the second wedge block, causing the first piston to pass over the second wedge block, so that the first piston quickly approaches the second piston and resets under the action of the rebound force of the first spring, thereby squeezing the air between the first piston and the second piston into the lifting airbag through the second one-way valve and the air pipe. As the turntable continues to rotate, the second wedge block on the second piston collides with the first wedge block, and the first piston sucks air into the shell. Finally, the above operation is repeated to inflate the lifting airbag and the wrapping airbag, thereby reducing the weight of the glasses body as much as possible, achieving lightweight VR glasses, and minimizing the burden on users when wearing the glasses body.

The air tube 150 is arranged in a "Y" shape, the single end of the air tube 150 is connected to the inflation component 130, and the double ends of the air tube 150 are respectively connected to the two lifting airbags 120.

[0039] A vent hole 160 is provided on the side of the trachea 150, and a baffle 170 for sealing the vent hole 160 is rotatably provided inside the trachea 150, and a rotating shaft 171 is fixedly installed on the outside of the baffle 170. The number of the rotating shafts 171 is set to two, and the two rotating shafts 171 are respectively located on both sides of the baffle 170, and the ends of the rotating shafts 171 are rotatably inserted into the inner side of the trachea 150, and a torsion spring 172 is sleeved on the outside of the rotating shaft 171, one end of the torsion spring 172 is fixedly connected to the baffle 170, and the other end of the torsion spring 172 is fixedly connected to the inner wall of the trachea 150, and at this time, the torsion spring 172 is in a compressed state, so that the baffle 170 is tightly attached to the inner wall of the trachea 150 under the action of the rebound force of the torsion spring 172, thereby sealing the vent hole 160.

[0040] A degassing assembly 180 is provided on the upper side of the eyeglass body 100, and the degassing assembly 180 is used to release the sealing of the baffle 170 on the degassing hole 160. The degassing assembly 180 includes a second knob 181 rotatably inserted on the upper side of the eyeglass body 100, a push rod 182 threadedly connected to the inner side of the second knob 181, a rotating ring 183 fixedly installed in the middle of the second knob 181, a limiting ring 184 fixedly installed in the middle of the push rod 182, and a through hole 185 opened on the sides of the rotating ring 183 and the limiting ring 184, and the through hole 185 is connected to the outside air. The rotating ring 183 is rotatably inserted on the inner side of the eyeglass body 100, and the push rod 182 is movably arranged on the inner side of the eyeglass body 100.

[0041] In this embodiment: the inflatable component 130 fills air into the lifting airbag 120 through the air pipe 150, so that the lifting airbag 120 expands outward and increases in height until the upper surface of the lifting airbag 120 is higher than the upper surface of the lens 110, so that when a user wearing myopia glasses uses the eyeglass body 100, the lifting airbag 120 blocks the myopia glasses and the lens 110, thereby facilitating the protection of the lens 110, and solving the problem that when a user wearing myopia glasses uses VR glasses, the myopia glasses are easily bumped against the lenses of the VR glasses, causing the lenses of the VR glasses to be worn. Usually, an annular gasket is used to block the VR lenses and the myopia glasses, but the user needs to purchase an annular gasket separately and assemble it on the existing VR glasses, which is not convenient for protecting the lenses of the VR glasses; The second knob 181 is turned to move the push rod 182 downward, and the push rod 182 passes through the air bleed hole 160 and abuts against the baffle 170. The torsion spring 172 is compressed to push the baffle 170 downward, thereby releasing the seal of the baffle 170 on the air bleed hole 160, so that the air in the lifting airbag 120 is discharged through the air pipe 150, the air bleed hole 160 and the through hole 185, and the lifting airbag 120 can be retracted and restored. Finally, the second knob 181 is turned in the opposite direction to move the push rod 182 upward and reset, so that the baffle 170 can be reset under the action of the rebound force of the torsion spring 172 to seal the air bleed hole 160 again.

[0042] Embodiment 2: This embodiment is intended to solve the problem that when the eyeglass body 100 is placed on a desktop, it is easy to touch other sundries, and the lens 110 is exposed to the outside, so it is easy to bump against sundries. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The outer side of the lifting airbag 120 is connected to a wrapping airbag 190, which is also arranged in a ring shape. The wrapping airbag 190 is connected to the lifting airbag 120, and the outer ring of the wrapping airbag 190 is arranged as a pleated surface that can expand outward, and the inner ring of the wrapping airbag 190 is arranged as a non-expandable smooth surface. The resistance to the deployment of the wrapping airbag 190 is greater than the resistance to the deployment of the lifting airbag 120, so that when inflated, the lifting airbag 120 expands and increases first, and then the wrapping airbag 190 expands and wraps.

[0043] In this embodiment: after the lifting airbag 120 is inflated and deployed, the inflation assembly 130 continues to inflate, so that the unfolded area of ​​the folds of the outer ring of the wrapping airbag 190 increases, while the area of ​​the smooth surface of the inner ring of the wrapping airbag 190 remains unchanged, so that the wrapping airbag 190 extends inward at its upper end opening, so that the upper end opening of the wrapping airbag 190 is reduced, the lens 110 is wrapped inside as much as possible, and the area of ​​the lens 110 exposed to the outside is reduced as much as possible, so that it is not easy to collide with debris.

[0044] Embodiment 3: This embodiment aims to solve the problem that the weight of the electric air pump is large, thereby increasing the weight of the eyeglass body 100 to a greater extent, which is contrary to the lightweight of VR glasses, thereby increasing the burden on the user to wear the eyeglass body 100 and increasing the battery load of the eyeglass body 100. The difference between this embodiment and embodiment 1 is that please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The inflation component 130 includes a shell 200 fixedly arranged inside the eyeglass body 100, a first one-way valve 201 and a second one-way valve 202 respectively interference-inserted on both sides of the shell 200, and a mesh 203 fixedly installed on the air inlet end of the first one-way valve 201. The air inlet end of the first one-way valve 201 is arranged on the outside of the eyeglass body 100 and is connected to the outside air. The air outlet end of the first one-way valve 201 is connected to the inner cavity of the shell 200. The outside air enters the shell 200 through the mesh 203 and the first one-way valve 201. The air inlet end of the second one-way valve 202 is connected to the inner cavity of the shell 200. The air outlet end of the second one-way valve 202 is connected to the trachea 150. The air in the shell 200 enters the lifting airbag 120 and the wrapping airbag 190 through the second one-way valve 202 and the trachea 150.

[0045] The inflation component 130 also includes a turntable 204 rotatably arranged inside the shell 200, a first piston 205 and a second piston 206 slidably arranged on the side of the turntable 204, a slider 207 fixedly connected to the first piston 205 and the second piston 206 respectively, a slide groove 208 opened on the side of the turntable 204 and used in conjunction with the slider 207, and a first spring 209 arranged between the slider 207 and the turntable 204. The lower end of the first knob 140 is inserted into the upper side of the shell 200, and the bottom of the first knob 140 is fixedly connected to the center of the turntable 204. The sides of the first piston 205 and the second piston 206 are both slidably matched with the inner wall of the shell 200, so that the first piston 205, the second piston 206 and the inner wall of the shell 200 are kept sealed. The slider 207 is slidably inserted in the slide groove 208, and the first spring 209 is arranged in the slide groove 208. The two ends of the first spring 209 are respectively fixedly connected to the slider 207 and the inner wall of the turntable 204.

[0046] A first wedge block 210 is slidably inserted into the inner side of the eyeglass body 100, and one end of the first wedge block 210 with an inclined surface is slidably inserted into the side wall of the shell 200, so that the inclined surface of the first wedge block 210 is located inside the shell 200, and a second spring 211 for resetting the first wedge block 210 is fixedly installed on the outer side of the first wedge block 210, and the end of the second spring 211 is fixedly connected to the inner wall of the eyeglass body 100 and sealed by conventional sealing means. The stiffness of the second spring 211 is greater than that of the first spring 209, and second wedge blocks 212 intermittently used in conjunction with the first wedge block 210 are fixedly installed on the outer sides of the first piston 205 and the second piston 206.

[0047] In this embodiment: the first knob 140 is turned, so that the rotary disk 204 drives the first piston 205 and the second piston 206 to rotate in the housing 200, and then the second wedge block 212 on the first piston 205 conflicts with the first wedge block 210, so that the first piston 205 is blocked and stationary, and at the same time the first spring 209 is compressed, and the second piston 206 that continues to rotate sucks the outside air into the housing 200 through the first one-way valve 201; Subsequently, the second piston 206 passes over the air inlet end of the second one-way valve 202. At the same time, the first spring 209 is compressed to the maximum extent and rebounds, causing the first piston 205 to start to rotate, thereby compressing the second spring 211 through the cooperation of the first wedge block 210 and the second wedge block 212, so that the first piston 205 passes over the second wedge block 212, so that the first piston 205 quickly approaches the second piston 206 under the action of the rebound force of the first spring 209 and resets, thereby squeezing the air between the first piston 205 and the second piston 206 into the lifting airbag 120 through the second one-way valve 202 and the air pipe 150. As the turntable 204 continues to rotate, the second wedge block 212 on the second piston 206 conflicts with the first wedge block 210, and the first piston 205 sucks air into the shell 200. Finally, the above operation is repeated to inflate the lifting airbag 120 and the wrapping airbag 190. During the inflation process, the user can adjust the inflation amount according to personal needs.

[0048] This technical solution drives the inflation component 130 to inflate the lifting airbag 120 and the wrapping airbag 190 by turning the first knob 140, thereby replacing the electric air pump and the battery, reducing the occupied space and overall weight of the eyeglass body 100, reducing the weight of the eyeglass body 100 as much as possible, and achieving lightweight VR glasses, thereby minimizing the burden on users when wearing the eyeglass body 100 and reducing the power load.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
