Description

Technical Field

[0001] This invention relates to the technical field of VR glasses, and more particularly to a head-mounted virtual reality (VR) glasses. Background Technology

[0002] With the rapid development of virtual reality technology, head-mounted virtual reality glasses, as an important immersive interactive device, have been widely used in various fields such as gaming, education and training, medical rehabilitation, and industrial design. By wearing VR glasses, users can obtain a highly immersive visual experience and achieve real-time interaction with the virtual environment.

[0003] To improve comfort and a secure fit, existing VR glasses typically feature a flexible rubber or silicone face pad around the circumference of the surface that contacts the user's face. This pad structure can adapt to different facial contours to some extent, reducing external light interference and enhancing visual immersion. However, while this sealed design improves fit, it also brings a series of physiological comfort issues: the relatively enclosed microenvironment created by the rubber pad around the face hinders airflow inside the glasses, making it difficult for heat and moisture to escape effectively. During prolonged wear, sweat and exhaled moisture accumulate in the confined space, easily forming condensation on the inner surface of the lenses, severely affecting visual clarity. Simultaneously, the high temperature and humidity keep the facial skin in a stuffy state for extended periods, easily causing itching, allergies, and even inflammation. Furthermore, the continuous pressure of the face pad on the eye and cheekbone areas may obstruct local blood circulation, leading to pressure marks, numbness, or fatigue. Summary of the Invention

[0004] In view of this, the present invention provides a head-mounted virtual reality (VR) glasses that can overcome the defect of existing VR glasses, which are prone to condensation on the inner surface of the lenses during use, thus seriously affecting visual clarity.

[0005] The technical solution is as follows: A head-mounted virtual reality (VR) glasses, comprising: a VR glasses body; a controller installed inside the VR glasses body; a strap installed on the VR glasses body; fans symmetrically installed on both sides of the VR glasses body; rubber pads connected to the sides of the VR glasses body; a first airbag circumferentially spaced and connected to the sides of the rubber pad; a second airbag circumferentially spaced and connected to the sides of the rubber pad, and the second airbag and the first airbag are arranged alternately; and a control component disposed inside the VR glasses body for controlling the expansion or contraction of the first airbag and the second airbag.

[0009] As a further preferred embodiment, the winding assembly includes: a connecting plate connected to the side of the strap; a guide tube connected to the connecting plate, with the pull cord slidingly passing through the inside of the guide tube; a housing connected to the side of the connecting plate, with the pull cord slidingly passing through the inside of the housing; a winding frame rotatably connected to the connecting plate, with the pull cord wound around the winding frame, and the winding frame located inside the housing; and a second motor mounted on the side of the connecting plate, with the output shaft of the second motor connected to the rotation shaft of the winding frame.

[0010] As a further preferred embodiment, it also includes: a mounting plate, disposed inside the VR glasses body; lenses, symmetrically connected to the mounting plate; a buffer spring, with its two ends connected to the mounting plate and the VR glasses body respectively; a bellows, with its two ends connected to the mounting plate and the VR glasses body respectively; and a piezoelectric ceramic resonator, mounted on the side of the mounting plate.

[0011] As a further preferred option, it also includes: a three-way pipe, which is connected to the inside of the VR glasses body.

Detailed Implementation

[0026] 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.

[0027] A type of head-mounted virtual reality (VR) glasses, such as Figures 1-5 As shown, the VR glasses include a VR glasses body 1, a controller 101, a strap 2, a fan 3, a rubber pad 4, a first airbag 5, a second airbag 6, and a control component. The controller 101 is installed on the upper left side of the inside of the VR glasses body 1. The strap 2 is installed on the rear of the VR glasses body 1. Fans 3 are installed on the rear of both the left and right sides of the inner wall of the VR glasses body 1. The rubber pad 4 is connected to the rear of the VR glasses body 1. Multiple first airbags 5 and multiple second airbags 6 are circumferentially connected to the rear of the rubber pad 4. The width of the first airbags 5 and the second airbags 6 is relatively small (the first airbags 5 and the second airbags 6 in the figure are only schematic diagrams). The second airbags 6 are arranged alternately with the first airbags 5, and both the first airbags 5 and the second airbags 6 are inclined. The VR glasses body 1 is equipped with a control component for controlling the expansion or contraction of the first airbags 5 and the second airbags 6.

[0028] like Figures 2-5As shown, the control assembly includes a first diversion pipe 7, a second diversion pipe 8, a first air pump 9, a second air pump 10, a hollow shell 11, a first connecting pipe 12, a second connecting pipe 13, and a switching mechanism. The first diversion pipe 7 is connected to the upper interior of the VR glasses body 1, and the front of each first airbag 5 is connected to and maintains communication with the rear end of the first diversion pipe 7. The second diversion pipe 8 is also connected to the upper interior of the VR glasses body 1, and the front of each second airbag 6 is connected to and maintains communication with the rear end of the second diversion pipe 8. The first air pump 9 and the second air pump 10 are installed on the upper right interior of the VR glasses body 1. The air inlet of the first air pump 9 and the air outlet of the second air pump 10 are both connected to the outer side of the VR glasses body 1. The hollow shell 11 is connected to the upper middle interior of the VR glasses body 1, and the front end of the first diversion pipe 7 and the second diversion pipe 8 are connected to the upper right interior of the VR glasses body 1. The front ends of the first air pump 9 are connected to the left and right sides of the hollow shell 11 and remain in communication. The air outlet of the first air pump 9 is connected to the rear side of the hollow shell 11 via a first connecting pipe 12 and remains in communication. The air inlet of the second air pump 10 is connected to the front side of the hollow shell 11 via a second connecting pipe 13 and remains in communication. The hollow shell 11 is provided with a switching mechanism for switching the communication states of the first diverter pipe 7, the second diverter pipe 8, the first connecting pipe 12, and the second connecting pipe 13. The switching mechanism includes a first motor 14 and a valve block 15. The first motor 14 is installed on the top of the hollow shell 11. The valve block 15 is rotatably connected inside the hollow shell 11. The outer wall of the valve block 15 contacts and seals with the inner wall of the hollow shell 11. The valve block 15 has a first channel 1501 and a second channel 1502 inside, and the top of the valve block 15 is connected to the output shaft of the first motor 14.

[0029] In the initial state, the first diversion pipe 7 is connected to the second connecting pipe 13 through the second channel 1502, and the second diversion pipe 8 is connected to the first connecting pipe 12 through the first channel 1501. The second airbag 6 is inflated, and the first airbag 5 is contracted. When the VR glasses are needed, the user can directly wear the strap 2 on their head to fix the VR glasses body 1 in front of their eyes. At this time, the second airbag 6 can conform to the user's face, while the first airbag 5 does not contact the user's face, thus forming an inclined exhaust channel between two adjacent second airbags 6. This inclined channel structure can effectively block most of the external light from entering the VR glasses while ensuring ventilation. Inside the VR headset 1, to avoid affecting the user's visual experience, the user can then use the VR headset 1. During use, the controller 101 can control the fan 3 to start working. The fan 3, through the aforementioned exhaust channel, can expel the hot air between the VR headset 1 and the user's face, thereby accelerating the air circulation inside the VR headset 1, achieving the purpose of removing heat and moisture, preventing condensation from forming on the lenses of the VR headset 1, and ensuring visual clarity. At the same time, the controller 101 can control the first motor 14 to drive the valve block 15 to intermittently rotate forward and backward by a specified angle. When the first motor 14 drives the valve block 15 to rotate forward by a specified angle, the first diverter pipe 7 can pass through the first channel 15. 01 is connected to the first connecting pipe 12, and the second diversion pipe 8 is connected to the second connecting pipe 13 through the second channel 1502. Then, the controller 101 controls the first air pump 9 to work for 3 seconds. The first air pump 9 can inject air into the first airbag 5 through the first connecting pipe 12 and the first diversion pipe 7, causing the first airbag 5 to inflate and fit against the user's face. After 3 seconds, the controller 101 controls the first air pump 9 to stop working and controls the second air pump 10 to work for 3 seconds. The second air pump 10 can draw air from the inside of the second airbag 6 through the second connecting pipe 13 and the second diversion pipe 8, causing the second airbag 6 to contract and detach from the user's face. After 3 seconds, the controller 101 controls the second air pump 10 to stop. When the operation stops, an inclined exhaust channel is formed between the two adjacent first airbags 5. The fan 3 blows air out through the exhaust channel, which can also locally dissipate heat from the part of the user's face that is in contact with the second airbag 6, preventing the user's face from experiencing skin itching, allergies, or even inflammatory reactions. It can also prevent the user's face from experiencing pressure marks, numbness, or fatigue. Conversely, when the first motor 14 drives the valve block 15 to reverse to a specified angle, the second airbag 6 can be inflated and the first airbag 5 can be contracted through the cooperation of the first air pump 9 and the second air pump 10. This repeated process allows the first airbag 5 and the second airbag 6 to alternately inflate and contract, achieving the purpose of massaging the user's face and improving the user's wearing comfort.

[0030] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, it also includes a pressure sensor 16, a sleeve 17, a pull cord 1701, a chest strap 18, and a winding assembly. The pressure sensor 16 is installed on the lower rear side of the rubber pad 4. The top of the strap 2 is connected to the sleeve 17. The pull cord 1701 is slidably connected inside the sleeve 17, and the front end of the pull cord 1701 is connected to the front top of the VR glasses body 1. The rear end of the pull cord 1701 is connected to the chest strap 18. The strap 2 is provided with a winding assembly for winding the pull cord 1701. The winding assembly includes a connecting plate 19, a wire conduit 20, a housing 21, a winding frame 22, and a second motor 23. The connecting plate 19 is connected to the middle rear side of the strap 2. The upper part of the connecting plate 19 is connected to the guide tube 20, which is inclined, and the pull rope 1701 slides through the inner side of the guide tube 20. The lower front part of the connecting plate 19 is connected to the outer shell 21, and the pull rope 1701 slides through the inside of the outer shell 21. The winding frame 22 consists of a rotating frame and two rollers. The lower part of the connecting plate 19 is rotatably connected to the rotating frame, which is located inside the outer shell 21. Rollers are rotatably connected to both the upper and lower sides of the rotating frame, and the pull rope 1701 passes around the two rollers in sequence. The lower rear part of the connecting plate 19 is equipped with a second motor 23, and the output shaft of the second motor 23 is connected to the rear end of the rotating shaft of the winding frame 22.

[0031] When a user wears the VR headset 1 on their head using the strap 2, the VR headset 1 exerts significant pressure on the user's nose. The pressure sensor 16 monitors the pressure on the user's nose in real time. The user also needs to wear the chest strap 18 around their chest. When the pressure sensor 16 detects that the pressure on the user's nose exceeds a preset value, the pressure sensor 16 sends a signal. Upon receiving the signal, the controller 101 controls the second motor 23 to drive the winding frame 22 to rotate. The winding frame 22 winds up the pull rope 1701, and the front end of the pull rope 1701 can pull the VR headset. The top front of the VR glasses body 1 moves upward, thereby slowly raising the VR glasses body 1 to reduce the pressure on the user's nose bridge and improve wearing comfort. When the pressure sensor 16 detects that the pressure on the user's nose bridge is less than the preset value, the pressure sensor 16 sends a signal. After receiving the signal, the controller 101 controls the second motor 23 to stop working. When the user is not using the VR glasses, the chest strap 18 must be untied first, and then the strap 2 must be removed. Then, the controller 101 controls the second motor 23 to drive the winding frame 22 to reverse and reset, so that the winding frame 22 loosens the pull rope 1701.

[0032] like Figure 8 and Figure 9As shown, it also includes a mounting plate 24, glass lenses 25, buffer springs 26, bellows 27, piezoelectric ceramic resonators 28, and a three-way pipe 29. The VR glasses body 1 has a mounting plate 24 inside. A rubber ring is circumferentially arranged on the outer side of the mounting plate 24, contacting the inner wall of the VR glasses body 1. Glass lenses 25 are symmetrically mounted on the mounting plate 24. Buffer springs 26 are symmetrically connected between the front side of the mounting plate 24 and the VR glasses body 1. Bellows 27 are symmetrically connected between the front side of the mounting plate 24 and the VR glasses body 1. The front and rear ends of the corrugated pipe 27 are connected to the glass lens 25 and the lens of the VR glasses body 1, respectively. A piezoelectric ceramic resonator 28 is installed in the middle of the front side of the mounting plate 24. A three-way pipe 29 is connected to the upper inside of the VR glasses body 1. The front end of the three-way pipe 29 is connected to the second connecting pipe 13 and remains connected. The other two ends of the three-way pipe 29 are connected to the rear top of the two corrugated pipes 27 and remain connected. Multiple through holes 30 are circumferentially spaced at the outer edge of the glass lens 25 on the mounting plate 24, and the through holes 30 are connected to the corrugated pipes 27.

[0033] When not in use, the mounting plate 24 and glass lens 25 block the back of the lenses of the VR glasses body 1, thus preventing dust from adhering to the lenses of the VR glasses body 1. When the user needs to use the VR glasses, the piezoelectric ceramic resonator 28 can be powered on by the controller 101. The piezoelectric ceramic resonator 28 will vibrate, causing the mounting plate 24 and glass lens 25 to vibrate. The buffer spring 26 and bellows 27 can adapt by extending and retracting, thereby shaking off the dust adhering to the surface of the glass lens 25. Meanwhile, the controller 101 controls the second air pump 10 to work. The second air pump 10 can draw air from the inside of the corrugated pipe 27 through the second connecting pipe 13 and the three-way pipe 29, so that the through hole 30 generates suction to suck up the dust shaken off the surface of the glass lens 25. The dust can eventually be discharged through the second air pump 10 to achieve the purpose of self-cleaning. Then, the user can wear the VR glasses body 1 on his head through the strap 2. At this time, the user can use the VR glasses body 1 normally through the glass lens 25 and the corrugated pipe 27. The corrugated pipe 27 plays a role in blocking light.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
