Description

Technical Field

[0001] This invention relates to the field of VR glasses technology, specifically to a VR glasses training device with high safety and comfort. Background Technology

[0002] VR glasses are virtual reality head-mounted display devices, generally categorized into external head-mounted displays, all-in-one head-mounted displays, and mobile head-mounted displays. VR glasses utilize head-mounted displays to block out a person's vision and hearing from the outside world, guiding the user to experience a feeling of being in a virtual environment. The display principle involves the left and right eye screens displaying images for the left and right eyes respectively; the human eye receives this differentiated information and then generates a sense of depth in the brain.

[0003] Currently, existing VR glasses training devices have overly simple structures, resulting in poor stability when worn. They are susceptible to external forces or vibrations, making them prone to loosening and falling off, which in turn affects comfort and reduces performance. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a VR glasses training device with high safety and comfort, comprising a protective helmet, a stabilizing device on the inner surface of the protective helmet, a positioning device at the center of the top of the protective helmet, a wireless earphone fixedly connected to the outer surface of the protective helmet, an elastic strap fixedly connected to the outer surface of the protective helmet near the wireless earphone, and a VR glasses mechanism fixedly connected to the end of the elastic strap away from the protective helmet. The entire device is worn on the user's head through the protective helmet, and the VR glasses mechanism is placed at the eye area. The elastic force provided by the contraction of the elastic strap makes the outer surface of the VR glasses mechanism fit against the eyes. Sound is emitted by the wireless earphone, and images are viewed through the VR glasses mechanism, thus enabling VR glasses training. The protective helmet protects the user's head.

[0005] The stabilizing device includes a clamping device. The top of the clamping device is rotatably connected to the inner surface of the protective helmet. An elastic support bladder is fixedly connected to the outer surface of the clamping device. An elastic support piece is fixedly connected to the outer surface of the clamping device near the elastic support bladder. The end of the elastic support piece away from the clamping device is fixedly connected to the inner surface of the protective helmet. A telescopic leather sleeve is fixedly connected to the outer surface of the clamping device near the bottom. The end of the telescopic leather sleeve away from the clamping device is fixedly connected to the inner surface of the protective helmet. When worn, the user's head applies pressure to the clamping device. Combined with the rotatable connection between the top of the clamping device and the inner surface of the protective helmet, the elastic support bladder and the elastic support piece are compressed. The combination of action and reaction forces makes the entire device more stable when worn.

[0006] Preferably, there are two clamping devices, and the two clamping devices are located on opposite sides of the positioning device, and the outer surface of the elastic support sheet is arc-shaped.

[0007] Preferably, the clamping device includes a clamping base plate, the top of which is rotatably connected to the inner surface of the protective helmet, the outer surface of the elastic support bladder is fixedly connected to the outer surface of the clamping base plate, the left end of the elastic support piece is fixedly connected to the outer surface of the clamping base plate, a flexible protective edge is provided on the outer surface of the clamping base plate near its edge, a ball-head pressing rod is fixedly connected to the top of the clamping base plate, and an ear protector is fixedly connected to the outer surface of the clamping base plate away from the telescopic leather sleeve. When the user's head presses the two symmetrical clamping base plates to the sides, the rotational connection between the top of the clamping base plate and the inner surface of the protective helmet compresses the elastic support bladder and the elastic support piece. Under the reaction force, the clamping base plate is subjected to the reverse elastic force of the elastic support bladder and the elastic support piece. Thus, under the pressing force, the outer surface of the flexible protective edge fits against the user's cheek. The flexible protective edge is made of rubber, which is flexible and has a non-slip effect. With the elastic support of the elastic support piece, the device is stable to wear and does not easily shake.

[0008] Preferably, the outer surface of the clamping substrate is arc-shaped, and the ball-head pressing rods are evenly distributed at the top of the clamping substrate.

[0009] Preferably, the ear protection device includes a sound-concentrating tube, the right end of which is fixedly connected to the outer surface of the clamping base plate. An annular air cavity is formed on the outer surface of the sound-concentrating tube away from the clamping base plate. An air passage is formed inside the sound-concentrating tube. The top end of the air passage communicates with the air port of the elastic support bladder, and the bottom end of the air passage communicates with the air port of the annular air cavity. An annular elastic membrane is fixedly connected to the outer surface of the sound-concentrating tube at the position of the annular air cavity. A soft layer is fixedly connected to the outer surface of the annular elastic membrane. A through hole is formed on the outer surface of the clamping base plate near the sound-concentrating tube. As the elastic support bladder is compressed, the internal gas is discharged and transported to the annular air cavity through the air passage. As the gas pressure increases, the annular elastic membrane causes the soft layer to expand. The soft layer is made of silicone, which is flexible and allows the outer surface of the soft layer to fit the user's ear, thus avoiding rigid pressure on the ear and improving wearing comfort. Furthermore, as the clamping base plate rotates, it drives the ball-head pressing rod to rotate, thereby applying pressure to the limiting device on the positioning device.

[0010] Preferably, the sound-concentrating tube is horn-shaped, and the through holes are evenly distributed on the outer surface of the clamping substrate and close to the sound-concentrating tube.

[0011] Preferably, the positioning device includes a housing, the bottom of which is fixedly connected to the center of the top of the protective helmet. A guide rod is slidably connected to the center of the top of the protective helmet, the bottom end of which penetrates the top of the protective helmet and extends into the interior. An arc-shaped support plate is fixedly connected to the top of the housing, and an elastic strip is fixedly connected to the inner surface of the arc-shaped support plate. The top end of the elastic strip is fixedly connected to the top of the inner wall of the housing. A limiting device is fixedly connected to the bottom end of the guide rod. When the protective helmet is worn on the user's head, under the pressure of the head and the slidable connection between the outer surface of the guide rod and the top of the protective helmet, the limiting device, upon contact with the user's head, applies an upward pressure to the arc-shaped support plate through the guide rod. This causes the elastic strip to deform under force, resulting in a reverse elastic force exerted by the elastic strip on the arc-shaped support plate. This helps the limiting device to limit the overall positioning of the protective helmet. Simultaneously, under the action of the clamping plate, the ball-head pressing rod applies pressing pressure to the limiting device again.

[0012] Preferably, the limiting device includes a conical pressure plate, the top center of which is fixedly connected to the bottom end of the guide rod, an elastic protrusion is fixedly connected to the inner surface of the conical pressure plate, and an elastic pressing device is fixedly connected to the inner surface of the conical pressure plate at its edge.

[0013] Preferably, the elastic pressing device includes an annular extension edge, an elastic washer is fixedly connected to the outer surface of the annular extension edge, and an elastic support member is fixedly connected to the outer surface of the annular extension edge away from the elastic washer. The top of the elastic support member is fixedly connected to the bottom edge of the conical pressure plate. When the user's head contacts the elastic protrusion, the elastic protrusion is made of rubber, which is flexible, thus making flexible contact between the patient's head and the conical pressure plate. Under the joint pressing of the ball head pressing rod and the guide rod, the conical pressure plate is limited, thus making the protective helmet highly stable when worn. At the same time, after the elastic pressing device is subjected to pressure, the annular extension edge, the elastic washer, and the elastic support member deform. The elastic washer is made of high-density sponge material, thus making flexible contact with the user's head.

[0014] Preferably, the outer surface of the annular extension edge is arc-shaped, and the elastic support members are evenly distributed on the outer surface of the annular extension edge and on the side away from the elastic washer.

[0015] This invention provides a VR glasses training device with high safety and comfort. It has the following beneficial effects:

[0016] 1. This highly safe and comfortable VR glasses training device comprises a protective helmet, a stabilizing device, a positioning device, wireless headphones, elastic straps, a VR glasses mechanism, a clamping device, an elastic support bladder, an elastic support plate, and a retractable leather sleeve. The entire device is worn on the user's head using the protective helmet, with the VR glasses mechanism positioned over the eyes. The elastic straps, when contracted, provide tension, ensuring the outer surface of the VR glasses mechanism conforms to the eyes. Sound is emitted through the wireless headphones, and images are viewed through the VR glasses, enabling VR glasses training. The protective helmet further protects the user's head, reducing the risk of injury. To prevent injury, the device utilizes the user's head to apply pressure to the clamping device during wear. The top of the clamping device rotates and connects to the inner surface of the protective helmet, compressing the elastic support bladder and elastic support plate. This combination of action and reaction forces makes the entire device more stable when worn. Furthermore, the interaction between the clamping devices connects the structural components, resulting in a simple and efficient design. It is easy to use, allows for elastic fixation, and offers good stability, reducing the impact of external forces or vibrations. It is less prone to loosening or falling off, provides high wearing comfort, and is safe and reliable, thus improving overall performance.

[0017] 2. This highly safe and comfortable VR glasses training device utilizes a clamping mechanism, clamping base plate, flexible protective edge, ball-head pressing rod, ear protector, sound-focusing cylinder, annular air chamber, airway, annular elastic membrane, soft layer, and through holes. When the user's head presses the symmetrical clamping base plate to both sides, the top of the clamping base plate rotates and connects to the inner surface of the protective helmet, causing the clamping base plate to compress the elastic support bladder and elastic support plate. Under the reaction force, the clamping base plate is subjected to the reverse elastic force of the elastic support bladder and elastic support plate. Furthermore, under the pressing pressure, the outer surface of the flexible protective edge conforms to the user's cheek. The flexible protective edge is made of rubber, offering good flexibility and anti-slip properties. With the elastic support plate providing elastic support, the entire device remains stable and does not easily shake. Simultaneously, as the elastic support bladder is compressed, internal gas is expelled and transported to the annular air chamber through the airway. As the gas pressure continuously increases, the annular air chamber... The elastic membrane causes the soft layer to expand, and the soft layer is made of silicone, which is flexible and allows its outer surface to fit snugly against the user's ears, thus avoiding rigid pressure on the ears and improving wearing comfort. As the clamping base rotates, it also rotates the ball-head pressing rod, applying pressure to the limiting device on the positioning mechanism, thus aiding in positioning. It fully utilizes the support and pressure of the user's head, allowing the clamping base to not only press the flexible protective edge, making soft contact with the cheek to reduce pain, but also, through reaction, support the elastic support bladder and elastic support sheet, providing good stability. Compression of the elastic support bladder helps to provide soft pressure on the user's ears, enhancing comfort. Furthermore, it can rotate the ball-head pressing rod, promoting the limiting device's control over the entire device and preventing wobbling. By utilizing the interaction between the structures, multiple functions are achieved, ensuring safety, reliability, and improved performance.

[0018] 3. This highly safe and comfortable VR glasses training device, through a clamping base plate, ball-head pressing rod, positioning device, shell, guide rod, arc support plate, elastic strip, and limiting device, works as follows: When the protective helmet is worn on the user's head, the pressure from the head, combined with the sliding connection between the outer surface of the guide rod and the top of the protective helmet, allows the limiting device to contact the user's head. The guide rod then applies upward pressure to the arc support plate, causing the elastic strip to deform under stress. Utilizing action and reaction forces, the elastic strip applies a reverse elastic force to the arc support plate, thus helping to limit the overall positioning of the protective helmet. Simultaneously, the clamping base plate causes the ball-head pressing rod to apply pressure to the limiting device, preventing wobbling. This cleverly connects the structures, making the overall device more stable, safe, and reliable, thus improving its performance.

[0019] 4. This highly safe and comfortable VR glasses training device utilizes a ball-head pressing rod, guide rod, limiting device, conical pressure plate, elastic protrusion, elastic pressing device, annular extension edge, elastic washer, and elastic support component. When the user's head contacts the elastic protrusion, the rubber material of the protrusion provides excellent flexibility, ensuring a flexible contact between the user's head and the conical pressure plate. The combined pressure of the ball-head pressing rod and guide rod limits the conical pressure plate, resulting in high stability when the protective helmet is worn. Simultaneously, the elastic pressing device deforms under pressure, causing the annular extension edge, elastic washer, and elastic support component to deform. The elastic washer is made of high-density sponge material, ensuring flexible contact with the user's head and avoiding rigid pressure, thus enhancing overall comfort. Through the interaction and interconnection of these structures, multiple functions are achieved, ensuring safety and reliability and improving performance. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0030] Example 1

[0031] Please see Figures 1-8 The present invention provides a technical solution: a VR glasses training device with high safety and comfort, including a protective helmet 1, a stabilizing device 2 provided on the inner surface of the protective helmet 1, a positioning device 3 provided at the top center of the protective helmet 1, a wireless earphone 4 fixedly connected to the outer surface of the protective helmet 1, an elastic strap 5 fixedly connected to the outer surface of the protective helmet 1 and close to the wireless earphone 4, and a VR glasses mechanism 6 fixedly connected to the end of the elastic strap 5 away from the protective helmet 1.

[0032] The stabilizing device 2 includes a clamping device 21. The top of the clamping device 21 is rotatably connected to the inner surface of the protective helmet 1. An elastic support bladder 22 is fixedly connected to the outer surface of the clamping device 21. An elastic support piece 23 is fixedly connected to the outer surface of the clamping device 21 near the elastic support bladder 22. One end of the elastic support piece 23 away from the clamping device 21 is fixedly connected to the inner surface of the protective helmet 1. A telescopic leather sleeve 24 is fixedly connected to the outer surface of the clamping device 21 near the bottom. One end of the telescopic leather sleeve 24 away from the clamping device 21 is fixedly connected to the inner surface of the protective helmet 1.

[0033] Two clamping devices 21 are provided, and the two clamping devices 21 are located on opposite sides of the positioning device 3. The outer surface of the elastic support piece 23 is arc-shaped. The entire device is worn on the user's head through the protective helmet 1, and the VR glasses mechanism 6 is placed in the eye area. The elastic force provided by the contraction of the elastic strap 5 makes the outer surface of the VR glasses mechanism 6 fit against the eyes. Sound is emitted by the wireless headphones 4, and the VR glasses mechanism 6 is used to view images, thus enabling VR glasses training. The protective helmet 1 can protect the user's head from injury. At the same time, when wearing it, the use of the wireless headphones 4 can help to protect the user's head from injury. The user's head applies pressure to the clamping device 21, and the top of the clamping device 21 rotates and connects with the inner surface of the protective helmet 1, causing the elastic support bladder 22 and the elastic support plate to be compressed. Combined with the action and reaction forces, the device becomes more stable when worn. Furthermore, the interaction between the clamping devices 21 and 21 connects the structures together, making the entire device structure reasonable and simple, easy to use, elastically fixed, and stable. It reduces the impact of external forces or vibrations, making it less prone to loosening or falling off. It offers high wearing comfort, safety, and reliability, thus improving performance.

[0034] Example 2

[0035] The clamping device 21 includes a clamping base plate 211, the top of which is rotatably connected to the inner surface of the protective helmet 1, the outer surface of the elastic support pouch 22 is fixedly connected to the outer surface of the clamping base plate 211, the left end of the elastic support piece 23 is fixedly connected to the outer surface of the clamping base plate 211, a flexible protective edge 212 is located on the outer surface of the clamping base plate 211 near the edge, a ball-head pressing rod 213 is fixedly connected to the top of the clamping base plate 211, and an ear protection device 214 is fixedly connected to the outer surface of the clamping base plate 211 on the side away from the telescopic leather sleeve 24.

[0036] The outer surface of the clamping substrate 211 is set to be arc-shaped, and the ball-head pressing rods 213 are evenly distributed on the top of the clamping substrate 211.

[0037] The ear protection device 214 includes a sound-concentrating tube 2141. The right end of the sound-concentrating tube 2141 is fixedly connected to the outer surface of the clamping base plate 211. An annular air cavity 2142 is formed on the outer surface of the sound-concentrating tube 2141 away from the clamping base plate 211. An air passage 2143 is formed inside the sound-concentrating tube 2141. The top end of the air passage 2143 communicates with the air port of the elastic support bladder 22. The bottom end of the air passage 2143 communicates with the air port of the annular air cavity 2142. An annular elastic membrane 2144 is fixedly connected to the outer surface of the sound-concentrating tube 2141 at the position of the annular air cavity 2142. A soft layer 2145 is fixedly connected to the outer surface of the annular elastic membrane 2144. A through hole 2146 is formed on the outer surface of the clamping base plate 211 near the sound-concentrating tube 2141.

[0038] The sound-focusing cylinder 2141 is horn-shaped, with through holes 2146 evenly distributed on the outer surface of the clamping base plate 211 near the sound-focusing cylinder 2141. When the user's head presses the two symmetrical clamping base plates 211 to the sides, the top of the clamping base plate 211 is rotatably connected to the inner surface of the protective helmet 1, causing the clamping base plate 211 to compress the elastic support bladder 22 and the elastic support sheet. Under the reaction force, the clamping base plate 211 is subjected to the reverse elastic force of the elastic support bladder 22 and the elastic support sheet. Under the pressure, the outer surface of the flexible protective edge 212 is made of rubber, which is flexible and has a non-slip effect. With the elastic support sheet, the device is stable and does not shake easily. At the same time, as the elastic support bladder 22 is compressed, the internal gas is discharged and transported to the annular air chamber 2142 through the air passage 2143. As the gas pressure continues to increase, the annular elastic membrane 2144 moves... The soft layer 2145 expands, and its material is made of silicone, which is flexible and allows its outer surface to fit snugly against the user's ear, thus avoiding rigid pressure on the ear and improving wearing comfort. As the clamping base plate 211 rotates, it drives the ball head pressing rod 213 to rotate, thereby applying pressure to the limiting device 35 on the positioning device 3, which helps with positioning. It makes full use of the support pressure of the user's head, so that the clamping base plate 211 can not only press the flexible protective edge 212 and make soft contact with the cheek to reduce pain, but also, under the reaction, support the elastic support bladder 22 and elastic support sheet, so that the protective helmet 1 is supported and has good stability. After the elastic support bladder 22 is compressed, it helps to gently press the user's ear, which is very comfortable. It can also drive the ball head pressing rod 213 to rotate, which promotes the limiting device 35 to limit the entire device and prevents wobbling. By utilizing the interaction between the structures, it is safe and reliable and improves the performance.

[0039] The positioning device 3 includes a housing 31. The bottom of the housing 31 is fixedly connected to the center of the top of the protective helmet 1. A guide rod 32 is slidably connected to the center of the top of the protective helmet 1. The bottom end of the guide rod 32 passes through the top of the protective helmet 1 and extends into the interior. An arc-shaped support plate 33 is fixedly connected to the top of the housing 31. An elastic strip 34 is fixedly connected to the inner surface of the arc-shaped support plate 33. The top end of the elastic strip 34 is fixedly connected to the top of the inner wall of the housing 31. A limit device 35 is fixedly connected to the bottom end of the guide rod 32. When the protective helmet 1 is worn on the user's head, under the pressure of the head, and in conjunction with the outer surface of the guide rod 32 and the protective helmet... The top sliding connection of 1 allows the limiting device 35 to apply upward pressure to the arc support plate 33 via the guide rod 32 after contacting the user's head. This causes the elastic strip 34 to deform under force, and the elastic strip 34 applies a reverse elastic force to the arc support plate 33 using action and reaction forces. This helps the limiting device 35 to limit the entire protective helmet 1. At the same time, under the action of the clamping base plate 211, the ball head pressing rod 213 applies pressing pressure to the limiting device 35 again, making it less prone to shaking. This cleverly connects the structures together, making the device more stable, safe and reliable, and improving its performance.

[0040] The limiting device 35 includes a conical pressure plate 351, the top center of which is fixedly connected to the bottom end of the guide rod 32, an elastic protrusion 352 is fixedly connected to the inner surface of the conical pressure plate 351, and an elastic pressing device 353 is fixedly connected to the inner surface of the conical pressure plate 351 at the edge.

[0041] The elastic pressing device 353 includes an annular extension edge 3531, an elastic washer 3532 is fixedly connected to the outer surface of the annular extension edge 3531, an elastic support member 3533 is fixedly connected to the outer surface of the annular extension edge 3531 and the side away from the elastic washer 3532, and the top end of the elastic support member 3533 is fixedly connected to the bottom edge of the conical pressure plate 351.

[0042] The outer surface of the annular extension edge 3531 is arc-shaped. The elastic support 3533 is evenly distributed on the outer surface of the annular extension edge 3531 and on the side away from the elastic washer 3532. When the user's head comes into contact with the elastic protrusion 352, the elastic protrusion 352 is made of rubber, which is flexible, so that the patient's head makes flexible contact with the conical pressure plate 351. Under the joint pressing of the ball head pressing rod 213 and the guide rod 32, the conical pressure plate 351 is limited, so that the protective helmet 1 is highly stable when worn. At the same time, after the elastic pressing device 353 is subjected to pressure, the annular extension edge 3531, the elastic washer 3532 and the elastic support 3533 deform. The elastic washer 3532 is made of high-density sponge material, so it makes flexible contact with the user's head and avoids rigid pressing, so that the overall wearing comfort is high. By utilizing the interaction and interconnection between the structures, multiple functions are realized, which is safe and reliable and improves the performance.

[0043] In use, the entire device is worn on the user's head using a protective helmet 1. When the user's head presses the symmetrical clamping plates 211 to both sides, the top of the clamping plates 211 rotates and connects to the inner surface of the protective helmet 1, causing the clamping plates 211 to compress the elastic support bladder 22 and the elastic support sheet. Under the reaction force, the clamping plates 211 are subjected to the reverse elastic force of the elastic support bladder 22 and the elastic support sheet. This pressure causes the outer surface of the flexible protective edge 212 to conform to the user's cheek. The flexible protective edge 212 is made of rubber, which is flexible and has a non-slip effect. Furthermore, the elastic support sheet ensures the overall stability of the device when worn. It is not easy to shake. As the elastic support bladder 22 is compressed, the internal gas is discharged and transported to the annular air chamber 2142 through the air passage 2143. As the gas pressure continues to increase, the annular elastic membrane 2144 drives the soft layer 2145 to expand. The soft layer 2145 is made of silicone, which is flexible and allows the outer surface of the soft layer 2145 to fit the user's ear, thus avoiding rigid pressure on the ear and making it highly comfortable to wear. As the clamping base plate 211 rotates, it drives the ball head pressing rod 213 to rotate, thereby applying pressing pressure to the limiting device 35 on the positioning device 3. When the protective helmet 1 is worn on the user's head, under the pressure of the head and combined with the outer surface of the guide rod 32, the helmet provides a comfortable fit. The surface is slidably connected to the top of the protective helmet 1, so that after the limiting device 35 contacts the user's head, it applies an upward pressure to the arc support plate 33 through the guide rod 32. This causes the elastic strip 34 to deform under force, so that the elastic strip 34 applies a reverse elastic force to the arc support plate 33, which helps the limiting device 35 to limit the entire protective helmet 1. At the same time, under the action of the clamping base plate 211, the ball head pressing rod 213 applies pressing force to the limiting device 35 again. Moreover, when the top of the user's head contacts the elastic protrusion 352, the elastic protrusion 352 is made of rubber, which is flexible, so that the top of the patient's head and the conical pressure plate 351 make flexible contact. The combined pressure of the rods 32 limits the conical pressure plate 351, thus ensuring high stability when wearing the protective helmet 1. At the same time, the elastic pressing device 353 deforms the annular extension edge 3531, the elastic washer 3532, and the elastic support 3533 when subjected to pressure. The elastic washer 3532 is made of high-density sponge material, which makes flexible contact with the user's head, avoiding rigid pressing and making the overall wearing comfort high. Then, the VR glasses mechanism 6 is placed on the eye area, and the elastic force provided by the contraction of the elastic strap 5 makes the outer surface of the VR glasses mechanism 6 fit the eyes. Sound is emitted by the wireless headphones 4, and the VR glasses mechanism 6 is used to view images, thus enabling VR glasses training.
