[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The head-mounted VR display device significantly improves the user experience by integrating the control system, advanced display system and unique airbag system in the VR glasses body. The display system adopts a gap design between the front display screen and the rear lens assembly to optimize visual immersion and image clarity.

[0016] 2. When the shielding airbag is rolled, contracted or opened, the first air pump and the second air pump work together to realize the automatic inflation and deflation of the shielding airbag; when the user no longer uses the VR glasses, the shielding cover is activated by the user's command to inflate the shielding airbag. After the shielding airbag is inflated, the two protruding airbags on the side close to the aspherical lens will just correspond to the two lens ends and fit tightly to the outside of the aspherical lens, forming an effective dustproof and buffering protection barrier. It can not only effectively isolate dust, particles and other impurities in the air, prevent them from adhering to the lens and affecting the visual effect, but also prevent the lens from being damaged due to long-term exposure to the outside, or damaged by external impact, thus extending the service life of the VR glasses.

[0017] 3. Through the setting of the airbag system, when the VR glasses accidentally fall, the built-in sensor can respond quickly and activate the airbag, causing it to quickly pop out from the tear and expand into a concave airbag structure, effectively forming an all-round protective barrier. It not only enhances the absorption capacity of the bottom impact, but also provides additional protection for the VR glasses body through the tight wrapping of the surrounding part, significantly improving the device's drop resistance and user safety.

[0018] 4. By setting each module in the facial cushion airbag system to fit the user's temple, eye socket and nose bridge, the user can make a personalized fit and adjust the inflation according to the individual facial contour to obtain the best comfort experience. The design of the airbag module can reduce the direct contact pressure between the VR glasses and the user's face, provide cushioning, reduce the discomfort of long-term wear, and allow users to focus more on the virtual reality experience.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] See also Figures 1 to 9 A head-mounted VR display device includes a VR glasses body 10, a head-mounted assembly 20 and an earphone module 30. A control system, a display system 40 and an airbag system 50 are arranged in the VR glasses body 10; the display system 40 includes a display screen 41 and a lens assembly 42. The display screen 41 is located at the front end of the VR glasses body 10, and the lens assembly 42 is located behind the display screen 41 and a gap is formed between the display screen 41; the airbag system 50 includes a safety airbag system 51 and a facial buffer airbag system 52. The safety airbag system 51 is arranged at the lower part of the VR glasses body 10, and the facial buffer airbag system 52 is distributed on the inner side of the outside of the VR glasses body 10; the head-mounted assembly 20 is fixedly arranged above the VR glasses body 10 and is an elliptical frame, and the earphone module 30 is arranged below the head-mounted assembly 20.

[0033] Specifically, the head-mounted VR display device significantly improves the user experience by integrating the control system in the VR glasses body 10, the advanced display system 40 and the unique airbag system 50. The display system 40 adopts a gap design between the front display screen 41 and the rear lens assembly 42 to optimize the visual immersion and image clarity. The airbag system 50 includes an internal safety airbag system 51 for protection against accidental impacts, and an external facial cushioning airbag system 52 to enhance wearing comfort and sealing. In addition, the structural design of the head-mounted assembly 20 can not only stably support the entire device, but also integrates the headphone module 30 at the bottom, so that users can enjoy the immersive enjoyment of synchronized sound and picture.

[0034] like Figure 1-2 As shown, the head-mounted assembly 20 includes a connecting portion 21, an adjusting portion 22 and a head frame portion 23. The head-mounted assembly 20 is fixedly connected to the VR glasses body 10 through the connecting portion 21, and the connecting portion 21 is an inverted triangle-shaped connecting block; the adjusting portion 22 is fixedly connected to the middle part of the connecting portion 21, and the adjusting portion 22 is an inverted U-shaped frame. The adjusting portion 22 includes a fixed frame 220 and two telescopic frames 221. The fixed frame 220 is fixed to the middle part of the connecting portion 21 and extends to both sides. A fixed card slot bar cooperating with the telescopic frame 221 is arranged inside the fixed frame 220, one end of the two telescopic frames 221 extends into the fixed frame 220 from both sides of the fixed frame 220 and is connected to the fixed card slot bar, and the other ends of the two telescopic frames 221 are respectively fixedly connected to both ends of the head frame 23.

[0035] Specifically, the head-mounted assembly 20 is firmly connected to the VR glasses body 10 through the inverted triangle-shaped connecting portion 21. The geometric characteristics of the inverted triangle provide connection strength in multiple directions, ensuring the stability of the device as a whole. The adjustment portion 22 cooperates with the fixed card slot strip inside the fixed frame 220 by setting a telescopic frame 221, allowing the user to freely adjust the tightness of the head frame portion 23 according to the size of the head circumference, thereby achieving a personalized wearing experience. Not only does it improve the wearing comfort, but it also ensures that different users can obtain the best fit and stability, further enhancing the immersion and comfort of the VR experience.

[0036] like Figure 2 As shown, the head frame 23 is a U-shaped frame, and a U-shaped groove 230 is opened on the lower side of the main body of the head frame 23, and a rotating sub-frame 231 is arranged inside the groove 230. The two ends of the rotating sub-frame 231 are respectively adjacent to the two ends of the groove 230 and are penetrated by rotating shafts 232. The rotating sub-frame 231 is rotatably connected to the head frame 23 through the two rotating shafts 232, and a pulling handle 233 is arranged in the middle of the rotating sub-frame 231.

[0037] In one embodiment, the rotating sub-frame 231 is flexibly connected to the edge of the groove 230 through the rotating shafts 232 at both ends, and the rotation function can be achieved by pulling the pull handle 233 provided in the middle. The rotating sub-frame 231 can be compactly accommodated in the groove 230 when not in use, keeping the device simple and beautiful; when wearing, the user only needs to easily pull the handle 233 to pull the rotating sub-frame 231 down to the neck to form a stable support point, effectively preventing the VR device from shaking during intense games or long-term wearing, greatly enhancing the stability and comfort of wearing, and can also meet the needs of different groups of people. For example, when children wear it, due to the relatively small head circumference and neck size of children, traditional VR devices often have difficulty in providing suitable fit and stability. The design of the rotating sub-frame 231 can be flexibly adjusted according to the neck size of the child to ensure that the VR device fits tightly and reduces light leakage and discomfort.

[0038] like Figure 2 As shown, the earphone module 30 includes an earphone 31, three fixing buckles 32, and an earphone jack 33. The earphone 31 is a wired earphone. The three fixing buckles 32 are arranged on the lower side of the head frame 23. The three fixing buckles 32 can fix the earphone wire of the earphone 31 to fit the head frame 23. The earphone jack 33 is arranged on one side of the VR glasses body 10. The earphone 31 realizes signal connection by inserting the earphone wire into the earphone jack 33.

[0039] Specifically, by placing the earphone 31 below the head frame 23 and using three fixing buckles 32 to fix the earphone cable, the earphone is highly integrated with the VR glasses body 10. Not only can the earphone 31 fit the user's head closely, but also the fixing buckle 32 can effectively prevent the earphone 31 from shaking or falling off during wearing, and avoid the cable from swinging and entangled when the user is active, thereby ensuring the stability of sound quality transmission.

[0040] In one embodiment, the fixing buckle 32 can be opened or closed, so that the user can easily open and remove the earphone 31, so that the earphone module 30 has a high adaptability, which provides great convenience for the user when it is necessary to replace earphones of different models or styles to meet personalized needs. In addition, with the continuous advancement of technology and the upgrading of earphones, users can easily upgrade the earphone module 30 without replacing the entire VR glasses, which prolongs the service life of the VR glasses device and reduces the cost of use.

[0041] like Figure 3-5 As shown, the lens assembly 42 is composed of two groups of aspherical lenses 420 and a lens shielding cover 43. The shielding cover 43 is arranged on the outside of the lens assembly 42. A sliding track 430 is also arranged below the shielding cover 43. The shielding cover 43 is in the shape of a scroll. The shielding cover 43 is composed of a first rotating shaft 431, a second rotating shaft 432 and a shielding airbag 433. Two protruding airbags are arranged on one side of the shielding airbag 433 close to the aspherical lens 420. The shielding airbag 433 is connected to the middle of the first rotating shaft 431 and the second rotating shaft 432. The first rotating shaft 431 is fixed to one side of the sliding track 430 and is adjacent to the aspherical lens 420 on the right side. Pulleys 434 are provided at both upper and lower ends of the second rotating shaft 432. The two pulleys 434 are respectively provided with traction shafts 435 on the upper and lower sides. A transverse groove 436 is also provided in the middle of the sliding track 430. The traction shaft 435 is inserted into the transverse groove 436 and is controlled by an electric machine to move left and right, and drives the second rotating shaft 432 to slide between the sliding track 430. The second rotating shaft 432 can rotate on its own.

[0042] In one embodiment, the start-up and closing process of the shielding cover 43 can be automated. The scroll shape of the shielding cover 43 and the design of the sliding track 430 control the movement of the traction shaft 435 in the transverse groove 436 through an electric machine, driving the pulleys 434 at the upper and lower ends of the second rotating shaft 432 to slide in the sliding track 430. In conjunction with the self-rotation function of the second rotating shaft 432, the shielding cover 43 can move left and right in the transverse groove 436, and the shielding airbag 433 can also be rolled, contracted or opened accordingly.

[0043] like Figure 4-7As shown, the shielding airbag 433 is an airbag cloth bag which is sealed on the upper and lower sides, and has air ports in the middle of the right side connected to the first rotating shaft 431 and the left side connected to the second rotating shaft 432. The first rotating shaft 431 and the second rotating shaft 432 are both hollow cylinders. A first air pipe 437 is provided in the middle of the first rotating shaft 431, which passes through the interior and extends to the right side. A first air pump 438 is connected to the interface end of the first air pipe 437 extending outside. The air port on the right side of the shielding airbag 433 is connected to the first air pump 438 through the internal interface of the first air pipe 437. A second air pipe 439 that passes through the interior is provided, and the air port on the left side of the shielding airbag 433 is provided inside the second rotating shaft 432 and connected to the internal interface of the second air pipe 439. A second air pump 440 is fixedly provided on an inner wall of the VR glasses body 10, and the second air pump 440 is adjacent to the end of the sliding rail 430 away from the first rotating shaft 431. A blocking tube 441 is extended outward from the side of the second air pump 440 close to the second rotating shaft 432. The blocking tube 441 is arranged opposite to the external interface of the second air pipe 439 and can extend into the second air pipe 439.

[0044] In one embodiment, when the shielding airbag 433 is rolled, contracted or opened, the first air pump 438 and the second air pump 440 work together to realize the automatic inflation and deflation of the shielding airbag 433; when the user no longer uses the VR glasses, the shielding cover 43 is activated by the user's command to inflate the shielding airbag 433. After the shielding airbag 433 is inflated, the two protruding airbags on the side close to the aspherical lens 420 will just correspond to the two lens ends and fit tightly to the outside of the aspherical lens 420, forming an effective dustproof and buffering protection barrier. It can not only effectively isolate dust, particles and other impurities in the air, prevent them from adhering to the lens and affecting the visual effect, but also prevent the lens from being damaged due to long-term exposure to the outside, or damaged due to external impact, thereby extending the service life of the VR glasses.

[0045] The shielding airbag 433 includes a non-inflated state and an inflated state; in the non-inflated state, the first air pump 438 and the second air pump 440 evacuate the air in the shielding airbag 433, and the shielding airbag 433 is in a state of a fitted double-layer airbag cloth. The shielding airbag 433 can be rolled, contracted or opened by the rotation and sliding of the second rotating shaft 432; in the inflated state, the second rotating shaft 432 slides to the farthest side away from the first rotating shaft 431, and the shielding airbag 433 opens accordingly, and the external interface connection of the second air tube 440 is engaged with the blocking tube 441, and the first air pump 438 and the second air pump 439 inflate the shielding airbag 433 through the first air tube 437 and the second air tube 439 respectively, so that the shielding airbag 433 is in an expanded state.

[0046] In one embodiment, a detailed description of the opening and closing process of the shielding cover 43 of the head-mounted VR display device of the present invention is also provided:

[0047] (1) Startup (opening) process:

[0048] ① User command trigger: When the user ends the VR experience and is ready to put the glasses aside, a command to start the shielding cover 43 is sent through a button on the VR glasses body 10, a voice command, or a supporting application.

[0049] ② Electric machine response: After receiving the command, the electric machine starts to work, and the traction shaft 435 moves smoothly in the transverse groove 436, driving the second rotating shaft 432 to slide along the sliding track 430 in a direction away from the first rotating shaft 431. At this time, the shielding airbag 433 is still in a non-inflated state, but gradually expands with the movement of the second rotating shaft 432.

[0050] ③ Preparation for airbag inflation: When the second rotating shaft 432 slides to a preset position (usually the farthest side away from the first rotating shaft 431), the external interface of the second air pipe 439 engages with the sealing tube 441. After the sealing tube 441 is inserted, the interface will be completely sealed to ensure the sealing of the airbag during inflation.

[0051] ④ Air pumps work in coordination: The first air pump 438 and the second air pump 440 are started simultaneously, and air is inflated into the shielding airbag 433 through the first air pipe 437 and the second air pipe 439 respectively. As the air is injected, the shielding airbag 433 gradually expands and fits tightly to the outer side of the aspherical lens 420, forming an effective dustproof and buffering protection barrier.

[0052] ⑤ Completion status confirmation: After the shielding airbag 433 is inflated, the system will confirm the status to ensure that the shielding cover 43 has been correctly opened and achieved the expected dustproof effect. At this time, the user can obtain relevant information through the indicator light, sound prompt or application interface on the VR glasses body 10.

[0053] (2) Closing (contraction) process:

[0054] ① User command trigger: When the user is ready to use the VR glasses again, a command to close the shielding cover 43 is sent in a corresponding manner.

[0055] ② The air pump evacuates the air bag: After receiving the command, the first air pump 438 and the second air pump 440 start to work, but this time they evacuate the gas in the shielding air bag 433. As the gas is discharged, the shielding air bag 433 gradually shrinks and becomes a close-fitting double-layer air bag cloth state.

[0056] ③ Electric machine response: While the airbag is shrinking, the electric machine is started again, and the traction shaft 435 drives the second rotating shaft 432 to slide along the sliding track 430 toward the first rotating shaft 431. As the second rotating shaft 432 moves, the shielding airbag 433 is further rolled and shrunk.

[0057] ④ Completion status confirmation: When the shielding cover 43 is completely retracted and attached to the first rotating shaft 431, the system will confirm the status to ensure that the shielding cover 43 is properly closed and ready for the next use. Similarly, the user can obtain relevant information through the indicator light, sound prompt or application interface on the VR glasses body 10.

[0058] like Fig. 9 As shown, the airbag system 51 includes an airbag 510, a tear 511 and a sensor. The tear 511 is a sealing opening formed by a rectangular tear line. The tear 511 is arranged at the lower center of the VR glasses body 10. The airbag 510 is shrunk and sealed inside the tear 511 as a whole. When the VR glasses body 10 falls, the internal sensor will trigger the airbag 510 to expand and enlarge after sensing. The airbag 510 pops out from the tear 511 and collides to form a concave airbag. The concave airbag is used to wrap the VR glasses body 10. The concave airbag includes a bottom buffer portion 512 and a surrounding portion 513 surrounding the edge of the bottom buffer portion 512. The surrounding portion 513 surrounds the periphery of the VR glasses body 10.

[0059] In one embodiment, the setting of the airbag system 51 enables the built-in sensor to respond quickly and activate the airbag 510 when the VR glasses accidentally fall, so that it quickly pops out from the tear 511 and expands into a concave airbag structure. This concave airbag is composed of a bottom buffer portion 512 and a surrounding portion 513 surrounding the periphery of the VR glasses body 10, effectively forming an all-round protective barrier, which not only enhances the absorption capacity of the bottom impact, but also provides additional protection for the VR glasses body 10 through the tight wrapping of the surrounding portion 513, significantly improving the device's drop resistance and user safety. In the inactive state, the airbag 510 is completely shrunk and sealed inside the tear 511, which does not affect the appearance of the device, while being able to provide protection when needed, and the design of the airbag 510 allows replacement after damage to maintain the protective function of the device.

[0060] In another embodiment, whether to activate the airbag system 51 can be controlled according to the user's selection to avoid ineffective application and damage of the airbag 510 in some cases of more intense movements.

[0061] like Figure 3 and Figure 8As shown, the facial cushioning airbag system 52 includes a first airbag module 520, a second airbag module 521, a third airbag module 522 and a micro air pump corresponding to each of the above airbag modules. The first airbag module 520 is used to fit the position of the user's temples on both sides, the second airbag module 521 is used to fit the user's upper and lower eye sockets, and the third airbag module 522 is used to fit the upper and lower parts of the user's nose bridge. The first airbag module 520, the second airbag module 521, and the third airbag module 522 can all use the corresponding micro air pumps to achieve independent inflation adjustment.

[0062] In one embodiment, each module in the facial cushioning airbag system 52 fits the user's temple, eye socket and nose bridge respectively, allowing the user to perform personalized adaptation and adjust the inflation according to the individual facial contour to obtain the best comfort experience. The design of the airbag module can reduce the direct contact pressure between the VR glasses and the user's face, provide cushioning, reduce the discomfort of long-term wear, and allow users to focus more on the virtual reality experience. By adjusting the inflation level of the airbag, it can also fit the user's face closely, reduce light leakage, and enhance the sense of immersion. The setting of the facial cushioning airbag system 52 can also absorb external impacts, protect the VR glasses body 10, and protect the user's face during use, preventing the user from immersing in the VR experience and colliding with the environment, causing injuries.

[0063] A fan system 60 is also provided in the VR glasses body 10 and the head-mounted assembly 20. The fan system 60 includes a first air outlet 61, a second air outlet 62 and a corresponding micro-fan assembly. There are two first air outlets 61, which are symmetrically arranged on both sides of the VR glasses body 10 close to the outer side of the lens assembly 42. The second air outlet 62 is located on the side of the connecting portion 21 that is recessed inwardly.

[0064] In one embodiment, the fan system 60 facilitates air circulation, improves thermal management and breathability, and reduces facial sweating and stuffiness. The first air outlet 61 is arranged in pairs near the outside of the lens assembly 42, which effectively speeds up the air circulation in the eye area, can evenly disperse the heat and moisture outside the lens assembly 42, reduce the stuffiness and fog accumulation caused by long-term wearing, and keep the vision clear; the second air outlet 62 is placed on the concave side of the connecting part 21 of the head-mounted assembly 20, further promoting the circulation of air around the head, reducing the stuffiness of the head, and enhancing the overall heat dissipation effect. The fan system 60 improves the comfort and durability of VR glasses, and also ensures a cool feeling for long-term use, significantly enhancing the overall use effect of the VR device. In addition, effective thermal management can ensure that the electronic components of the VR device operate at a suitable temperature, thereby maintaining the performance of the device and reducing performance degradation or device damage caused by overheating.

[0065] In another embodiment, the fan system 60 can also be used for regular dust blowing by using the first air outlets 61 arranged in pairs near the outer side of the lens assembly 42 to blow air to the lens assembly 42. The airflow generated by the fan can remove dust from the VR glasses lens and the interior to maintain a clear field of vision.

[0066] The present invention can achieve:

[0067] (1) The head-mounted VR display device significantly improves the user experience by integrating the control system in the VR glasses body 10, the advanced display system 40 and the unique airbag system 50. The display system 40 adopts a gap design between the front display screen 41 and the rear lens assembly 42 to optimize the visual immersion and image clarity. The airbag system 50 includes an internal safety airbag system 51 for protection against accidental impacts, and an external facial cushioning airbag system 52 to enhance wearing comfort and sealing. In addition, the structural design of the head-mounted assembly 20 can not only stably support the entire device, but also integrates the headphone module 30 at the bottom, so that users can enjoy immersive enjoyment of synchronized sound and picture.

[0068] (2) When the shielding airbag 433 is rolled, contracted or opened, the first air pump 438 and the second air pump 440 work together to realize the automatic inflation and deflation of the shielding airbag 433; when the user no longer uses the VR glasses, the shielding cover 43 is activated by the user's command to inflate the shielding airbag 433. After the shielding airbag 433 is inflated, the two protruding airbags on the side close to the aspherical lens 420 will just correspond to the two ends of the lens, and fit tightly to the outside of the aspherical lens 420, forming an effective dustproof and buffering protection barrier. It can not only effectively isolate dust, particles and other impurities in the air, prevent them from adhering to the lens and affecting the visual effect, but also prevent the lens from being damaged due to long-term exposure to the outside or damage caused by external impact, thereby extending the service life of the VR glasses.

[0069] (3) The setting of the airbag system 51 enables the built-in sensor to respond quickly and activate the airbag 510 when the VR glasses accidentally fall, so that it quickly pops out from the tear 511 and expands into a concave airbag structure. This concave airbag is composed of a bottom buffer portion 512 and a surrounding portion 513 surrounding the periphery of the VR glasses body 10, effectively forming an all-round protective barrier, which not only enhances the absorption capacity of the bottom impact, but also provides additional protection for the VR glasses body 10 through the tight wrapping of the surrounding portion 513, significantly improving the device's drop resistance and user safety. In the inactive state, the airbag 510 is completely shrunk and sealed inside the tear 511, which does not affect the appearance of the device, while being able to provide protection when needed. The design of the airbag 510 allows replacement after damage to maintain the protective function of the device.

[0070] (4) Each module in the facial cushioning airbag system 52 fits the user's temple, eye socket and nose bridge respectively, allowing the user to perform personalized adaptation and adjust the inflation according to the individual facial contour to obtain the best comfort experience. The design of the airbag module can reduce the direct contact pressure between the VR glasses and the user's face, provide cushioning, reduce the discomfort of long-term wear, and allow users to focus more on the virtual reality experience. By adjusting the inflation level of the airbag, it can also fit the user's face closely, reduce light leakage, and enhance the sense of immersion. The setting of the facial cushioning airbag system 52 can also absorb external impacts, protect the VR glasses body 10, and protect the user's face during use, preventing the user from immersing in the VR experience and colliding with the environment, which may cause injuries.

[0071] (5) The fan system 60 is provided to facilitate air circulation, improve heat management and air permeability, and reduce facial sweating and stuffiness. The first air outlet 61 is provided in pairs near the outside of the lens assembly 42, which effectively accelerates the air circulation in the eye area, can evenly disperse the heat and moisture outside the lens assembly 42, reduce the accumulation of stuffiness and fog caused by long-term wearing, and maintain clear vision; the second air outlet 62 is placed on the concave side of the connection part 21 of the head-mounted assembly 20, further promoting the circulation of air around the head, reducing the stuffiness of the head, and enhancing the overall heat dissipation effect. The fan system 60 improves the comfort and durability of the VR glasses, and also ensures a cool feeling after long-term use, significantly enhancing the overall use effect of the VR device.
