Technical Field

[0001] This invention belongs to the field of virtual glasses technology, and in particular relates to a virtual reality 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] A head-mounted virtual reality (VR) glasses with publication number CN120949453A includes a VR glasses body, fans installed on both sides of the VR glasses body, rubber pads connected to the sides of the VR glasses body, and a first airbag and a second airbag spaced apart on the sides of the rubber pads, with the second airbag and the first airbag arranged alternately.

[0004] When the aforementioned virtual reality (VR) glasses are in use, they rely on the first and second airbags on the rubber pads to contact the face. An inclined exhaust channel directly connects the first and second airbags to the external environment. Furthermore, the alternating expansion and contraction of the first and second airbags makes the VR glasses susceptible to interference from external light, thus affecting the user experience. Additionally, due to the large contact area between the airbags and the face, prolonged wear can lead to poor ventilation in the facial contact area, affecting wearing comfort. Summary of the Invention

[0007] The elastic massage unit includes a guide tube connecting the inflation chamber and the exhaust chamber. A point massage element is slidably disposed inside the guide tube. An elastic airbag connected to the point massage element is installed inside the guide tube facing the inflation chamber. When the inflation chamber is in an inflated state, the elastic airbag expands and pushes the point massage element to press on the face. The open and closed tube assembly allows the airflow in the inflation chamber to flow into the exhaust chamber. The airflow flowing through the exhaust chamber realizes the discharge of temperature and humidity in the facial contact area.

[0008] In one implementation of the present invention, the bottom of the opening side of the VR glasses body is provided with a curved mounting port and a limiting mounting port, the VR glasses body is provided with VR glasses lenses adapted to the distance between the eyes, and strap mounting heads are fixed on opposite sides of the VR glasses body, the strap mounting heads being used to connect elastic fixing straps.

[0009] Preferably, the mask assembly further includes a mask frame and a nose bridge support ring, the nose bridge support ring is fixedly installed at the bottom of the mask frame, the nose bridge support ring is gap-fitted into the inside of the curved mounting opening, and the mask frame is detachably installed on the opening side of the VR glasses body.

[0010] Furthermore, the nose bridge support ring has an internal hollow structure, and the inner wall of the nose bridge support ring is evenly provided with a number of heat dissipation holes communicating with its inner cavity. The inflation cavity and the exhaust cavity are both located inside the mask frame. The inflation cavity is separated from the inner cavity of the nose bridge support ring, while the exhaust cavity is connected to the inner cavity of the nose bridge support ring.

[0011] More specifically, a hollow air guide seat is fixedly provided at the bottom of the mask frame on one side of the nose bridge support ring. The hollow air guide seat is tightly inserted into the limiting installation port. An air supply connector is installed at the bottom of the hollow air guide seat and communicates with its inner cavity. The inner cavity of the hollow air guide seat is connected to the inflation cavity.

[0012] In the above scheme, the mask frame has an exhaust grille on the side opposite to the opening and closing pipe assembly that communicates with the exhaust chamber. The opening and closing pipe assembly consists of a guide pipe and a miniature solenoid valve. The miniature solenoid valve is installed on the guide pipe. The guide pipe is fixed on the mask frame and communicates with the inflation chamber and the exhaust chamber.

[0013] In some embodiments, the guide tube is fixedly disposed between the inflation chamber and the exhaust chamber, the point massage component consists of a massage ball, a connecting rod and a moving disc, the massage ball and the moving disc are respectively fixed to both ends of the connecting rod, and the elastic airbag is fixedly connected to the moving disc.

[0014] In this embodiment, a U-shaped guide tube is fixedly installed on the top of the VR glasses body, and an air supply connector 2 communicating with its inner cavity is installed on one side of the U-shaped guide tube.

The blower pipe has a blower opening facing the VR glasses lens side.

[0016] The present invention has the following beneficial effects: 1. The present invention can avoid external light interference by attaching the mask frame to the user's face. At the same time, an exhaust channel is provided on the side of the mask frame that is attached to the face, which reduces the contact area between the mask frame and the face when wearing it. The air flow through the exhaust channel realizes heat and moisture removal in the face contact area, which can alleviate facial discomfort during the wearing of VR glasses.

[0017] 2. This invention uses the air pressure in the inflation cavity to drive the deformation of each elastic airbag, which in turn pushes the massage points to press on the user's face. After the micro solenoid valve on the guide tube is opened, the air flow in the inflation cavity is discharged into the exhaust cavity under the action of air pressure. Through the alternating inflation and exhaust of the inflation cavity, the massage points can provide intermittent massage to the user's face to reduce discomfort during long-term wear.

[0018] 3. In use, this invention delivers airflow into the inner cavity of the U-shaped guide tube. The airflow entering the U-shaped guide tube is dispersed into each blower tube along the ventilation tubes on both sides. The airflow entering the blower tube flows along the air outlet across the surface of the VR glasses lens, which can sweep the surface of the VR glasses lens to remove dust or attached fog. The airflow entering the inner cavity of the VR glasses body through the air outlet is discharged along the second exhaust grille, realizing air circulation in the inner cavity of the VR glasses body to avoid the feeling of stuffiness and discomfort on the face during use.

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.

[0032] Example 1, please refer to Figures 1 to 10 This invention relates to a virtual reality glasses, comprising a VR glasses body 1; a mask assembly 2 for attaching to the face and bridge of the nose is installed on the open side of the VR glasses body 1; wherein, the mask assembly 2 includes an inflation cavity 3, an exhaust cavity 4, and an elastic massage part 6; the inflation cavity 3 is disposed on the side close to the VR glasses body 1; the exhaust cavity 4 is connected to the inflation cavity 3 through an opening and closing tube assembly 5; the elastic massage part 6 is arranged in a circumferential array within the exhaust cavity 4 and is used to perform point massage on the contact area between the mask assembly 2 and the face.

[0033] The elastic massage unit 6 includes a guide tube 7 that connects the inflation chamber 3 and the exhaust chamber 4. A point massage element is slidably installed inside the guide tube 7. An elastic airbag 8 connected to the point massage element is installed inside the guide tube 7 on the side facing the inflation chamber 3. When the inflation chamber 3 is in an inflated state, the elastic airbag 8 expands and pushes the point massage element to press the face. The open and closed tube assembly 5 in the open state allows the airflow in the inflation chamber 3 to flow into the exhaust chamber 4. The airflow flowing through the exhaust chamber 4 realizes the discharge of temperature and humidity in the facial contact area.

[0034] The specific structure of the VR glasses body 1 in this invention is as follows: Figure 5 As shown, the VR glasses body 1 has a curved mounting port 9 and a limiting mounting port 10 at the bottom of the opening side. The VR glasses body 1 has VR glasses lenses 11 that are adapted to the distance between the eyes inside. The VR glasses body 1 has strap mounting heads 12 fixed on both sides of the opposite sides. The strap mounting heads 12 are used to connect elastic fixing straps. The VR glasses body 1 can be worn between the user's eyes and nose bridge by the elastic fixing straps connected between the strap mounting heads 12.

[0035] The specific structure of the mask assembly 2 in this invention is as follows: Figure 6 As shown, the mask assembly 2 also includes a mask frame 13 and a nose bridge support ring 14. The nose bridge support ring 14 is fixedly installed at the bottom of the mask frame 13 and is fitted with the curved mounting opening 9 with a gap. The mask frame 13 is detachably installed on the opening side of the VR glasses body 1. This structural design allows for a fitting installation between the mask assembly 2 and the VR glasses body 1.

[0036] Furthermore, such as Figure 8 and Figure 6 As shown, the nose bridge support ring 14 has an internal hollow structure, and the inner wall of the nose bridge support ring 14 is evenly provided with a number of heat dissipation holes 15 that communicate with its inner cavity. The inflation cavity 3 and the exhaust cavity 4 are both located inside the mask frame 13. The inflation cavity 3 is separated from the inner cavity of the nose bridge support ring 14, while the exhaust cavity 4 is in communication with the inner cavity of the nose bridge support ring 14. The mask frame 13 is adapted to the user's facial features and can fit the user's face. At the same time, the nose bridge support ring 14 is also adapted to the user's nose bridge features and can fit the user's nose bridge.

[0037] Furthermore, such as Figure 3 and Figure 8 As shown, a hollow air guide seat 16 is fixedly provided at the bottom of the mask frame 13 on one side of the nose bridge support ring 14. The hollow air guide seat 16 is tightly inserted into the limiting installation port 10. An air supply connector 17 communicating with its inner cavity is installed at the bottom of the hollow air guide seat 16. The inner cavity of the hollow air guide seat 16 is connected to the inflation cavity 3. The air supply connector 17 is connected to the first air supply device through an external hose. The air outlet of the first air supply device is equipped with a solenoid valve.

[0038] In this embodiment of the invention, as Figures 6 to 9 As shown, the mask frame 13 has an exhaust grille 18 on the side opposite to the opening and closing pipe assembly 5, which is connected to the exhaust chamber 4. The opening and closing pipe assembly 5 consists of a guide pipe 19 and a miniature solenoid valve 20. The miniature solenoid valve 20 is installed on the guide pipe 19. The guide pipe 19 is fixed on the mask frame 13 and connects the inflation chamber 3 and the exhaust chamber 4. When the miniature solenoid valve 20 on the guide pipe 19 is opened, the gas in the inflation chamber 3 is discharged into the exhaust chamber 4 through the guide pipe 19, and then flows through the exhaust chamber 4 and is discharged from the exhaust grille 18.

[0039] In use, the control system activates the first air supply device and its solenoid valve, delivering a certain amount of airflow along the hollow guide seat 16 into the inflation chamber 3. Each elastic airbag 8 deforms under the air pressure in the inflation chamber 3, pushing the point massage pieces to press against the user's face. Then, the control system closes the first air supply device and its solenoid valve, while simultaneously activating the miniature solenoid valve 20 on the guide tube 19. At this time, the airflow in the inflation chamber 3, under air pressure, is discharged along the guide tube 19 into the exhaust chamber 4. The air entering the exhaust chamber 4 flows through the mask frame 13 and the face... The airflow in the face contact area helps to de-heat and dehumidify the face, alleviating facial discomfort during the wearing of the VR glasses 1. The airflow through the exhaust duct 4 is discharged along the exhaust grille 18. After a set time, the control system closes the micro solenoid valve 20 on the guide pipe 19 again, and at the same time opens the first air supply device and its solenoid valve. In the same way, the massage points can provide intermittent massage to the user's face, and the airflow in the face contact area between the cover frame 13 and the face can be used to reduce stuffiness and discomfort.

[0040] Specifically, the initial air supply pressure value output by the first air supply device into the inflation chamber 3 is preferably set to P=15kPa-25kPa to ensure that the thrust generated by the elastic airbag 8 can overcome the pressing resistance without causing damage to the facial soft tissue; the set time period for alternating inflation and deflation is set to Its satisfaction ,in The total volume of the inflatable cavity and elastic airbag. This refers to the air intake flow rate of the first gas supply device. The deformation holding time is preferably 3s-5s.

The point massage component consists of a massage ball 21, a connecting rod 22, and a moving disc 23. The massage ball 21 and the moving disc 23 are respectively fixed to both ends of the connecting rod 22. The elastic airbag 8 is fixedly connected to the moving disc 23. Figure 10 As shown, the elastic airbag 8 has a hemispherical structure. The edge of the opening end of the elastic airbag 8 is fixed to the inner wall of the guide tube 7, and the telescopic end of the elastic airbag 8 is fixed to the surface of the moving disk 23.

[0042] In this embodiment of the invention, as Figure 1 and Figure 5 As shown, a U-shaped air guide tube 24 is fixedly installed on the top of the VR glasses body 1. An air supply connector 25 communicating with the inner cavity of the U-shaped air guide tube 24 is installed on one side of the tube. This air supply connector 25 is connected to a second air supply device via an external hose. Inside the VR glasses body 1, an eye mask tube 27 coaxial with the VR glasses lens 11 is connected via a mounting plate 26. When worn, the eye mask tube 27 is attached to the area around the user's eyes, reducing the direct airflow from the inner cavity of the VR glasses body 1 to the user's eyes and avoiding discomfort such as tearing caused by direct airflow. An exhaust grille 28 is provided at the bottom of the VR glasses body 1. The airflow direction within the inner cavity of the VR glasses body 1 is as follows... Figure 2 and Figure 4 As shown by the arrow in the image.

[0043] In this embodiment of the invention, as Figure 4 and Figure 5 As shown, ventilation pipes 29 are installed on both inner walls of the VR glasses body 1. One end of the ventilation pipe 29 is connected to the inner cavity of the U-shaped guide pipe 24, and the other end of the ventilation pipe 29 is connected to a blower pipe 30 located on one side of the VR glasses lens 11. The blower pipe 30 has an air outlet 31 facing the VR glasses lens 11. In use, the control system controls the activation of the second air supply device, which delivers airflow to the inner cavity of the U-shaped guide pipe 24. The airflow entering the U-shaped guide pipe 24 is dispersed along the ventilation pipes 29 on both sides to each blower pipe 30. The airflow entering the blower pipe 30 flows along the air outlet 31 across the surface of the VR glasses lens 11, which can sweep the surface of the VR glasses lens 11 to remove dust or attached fog. The airflow entering the inner cavity of the VR glasses body 1 through the air outlet 31 is discharged along the exhaust grille 28, realizing air circulation in the inner cavity of the VR glasses body 1 to avoid facial stuffiness and discomfort during use.
