Description

Technical Field

[0001] This invention relates to the field of VR display device technology, and in particular to a head-mounted VR display device. Background Technology

[0002] With the rapid development of virtual reality technology, VR glasses have become an important tool for users to experience immersive experiences. However, existing VR glasses still have shortcomings in terms of user experience, safety, and device protection. For example, users may experience fatigue and discomfort in the area where their face contacts the VR glasses during prolonged wear; the devices are easily damaged by drops; the headphones cannot be replaced according to user needs; and dust and dirt easily accumulate on the lens area. Therefore, it is necessary to improve VR glasses to meet the actual needs of users. Summary of the Invention

[0003] Therefore, it is necessary to provide a head-mounted VR display device to solve at least one of the technical problems in the background art.

[0004] A head-mounted VR display device includes a VR glasses main body, a head-mounted assembly, and an earphone module. The VR glasses main body is equipped with a control system, a display system, and an airbag system. The display system includes a display screen and a lens assembly. The display screen is located at the front of the VR glasses main body, and the lens assembly is located behind the display screen, forming a gap between them. The airbag system includes a safety airbag system and a facial cushioning airbag system. The safety airbag system is located inside the lower part of the VR glasses main body, and the facial cushioning airbag system is distributed on the inner side of the exterior of the VR glasses main body. The head-mounted assembly is fixedly mounted on the top of the VR glasses main body and is an elliptical frame. The earphone module is located below the head-mounted assembly.

[0005] As a further improvement of the present invention, the head-mounted assembly includes a connecting part, an adjusting part, and a head frame part. The head-mounted assembly is fixedly connected to the VR glasses body through the connecting part, which is an inverted triangular connecting block. The adjusting part is fixedly connected to the middle of the connecting part, and the adjusting part is an inverted U-shaped frame. The adjusting part includes a fixed frame and two telescopic frames. The fixed frame is fixed to the middle of the connecting part and extends to both sides. The fixed frame is provided with a fixing slot strip that cooperates with the telescopic frame. One end of each of the two telescopic frames extends into the fixed frame from both sides and connects to the fixing slot strip. The other ends of the two telescopic frames are fixedly connected to both ends of the head frame part.

[0006] As a further improvement of the present invention, the head frame is a U-shaped frame, and a U-shaped groove is provided on the lower side of the main body of the head frame. A rotating sub-frame is provided inside the groove. Rotating shafts are provided at both ends of the rotating sub-frame near the two ends of the groove. The rotating sub-frame is rotatably connected to the head frame through the two rotating shafts. A pull handle is provided in the middle of the rotating sub-frame.

[0007] As a further improvement of the present invention, the headphone module includes a headphone, three fixing buckles, and a headphone jack. The headphone is a wired headphone. The three fixing buckles are located on the lower side of the head frame and can fix the headphone wire to fit the head frame. The headphone jack is located on one side of the VR glasses body. The headphone achieves signal connection by inserting the headphone wire into the headphone jack.

[0008] As a further improvement of the present invention, the lens assembly consists of two sets of aspherical lenses and a lens shield. The shield is located on the outside of the lens assembly, and a sliding track is provided below the shield. The shield is in the shape of a scroll and consists of a first rotating shaft, a second rotating shaft, and a shielding airbag. Two protruding airbags are provided on the side of the shielding airbag near the aspherical lens. The shielding airbag is connected to the middle of the first rotating shaft and the second rotating shaft. The first rotating shaft is fixed to one side of the sliding track and adjacent to the aspherical lens on the right side. Pulleys are provided at both the upper and lower ends of the second rotating shaft. Traction shafts are provided on the upper and lower sides of the two pulleys, respectively. A transverse groove is provided in the middle of the sliding track. The traction shaft is inserted into the transverse groove and is controlled by an electric motor to move left and right, and drives the second rotating shaft to slide between the sliding tracks. The second rotating shaft can rotate.

[0009] As a further improvement of the present invention, the shielding airbag is an airbag bag sealed on both the top and bottom sides, with air vents on the right side connected to the first rotating shaft and the left side connected to the second rotating shaft. Both the first and second rotating shafts are hollow cylindrical structures. A first air pipe is provided in the middle of the first rotating shaft, penetrating the interior and extending to the right. A first air pump is connected to the interface end of the first air pipe extending to the outside. The air vent on the right side of the shielding airbag is connected to the first air pump through the internal interface of the first air pipe. A second air pipe is provided inside the second rotating shaft, penetrating the interior. The air vent on the left side of the shielding airbag is located inside the second rotating shaft and connected to the internal interface of the second air pipe. A second air pump is fixedly provided on one inner side wall of the VR glasses body. The second air pump is located near the end of the sliding track away from the first rotating shaft. A sealing tube is provided on the side of the second air pump close to the second rotating shaft, extending outward. The sealing tube is positioned opposite to the external interface of the second air pipe and can extend into the interior of the second air pipe.

[0010] As a further improvement of the present invention, the shielding airbag includes a non-inflated state and an inflated state. In the non-inflated state, the first air pump and the second air pump evacuate the air from the shielding airbag, and the shielding airbag is in a state of fitting double-layer airbag fabric. The shielding airbag can be rolled up and contracted or opened by the rotation and sliding of the second rotating shaft. In the inflated state, the second rotating shaft slides to the farthest side away from the first rotating shaft, and the shielding airbag opens accordingly. The external interface of the second air tube is connected to the sealing tube, and the first air pump and the second air pump inflate the shielding airbag through the first air tube and the second air tube respectively, so that the shielding airbag is in an inflated state.

[0011] As a further improvement of the present invention, the airbag system includes an airbag, a tear, and a sensor. The tear is a sealed opening formed by a rectangular tear line and is located at the lower center of the VR glasses body. The airbag is fully contracted and sealed inside the tear. When the VR glasses body falls, the internal sensor senses the impact and triggers the airbag to expand. The airbag pops out from the tear and collides to form a concave airbag. The concave airbag is used to wrap the VR glasses body. The concave airbag includes a bottom buffer part and a surrounding part around the edge of the bottom buffer part. The surrounding part surrounds the periphery of the VR glasses body.

[0012] As a further improvement of the present invention, the facial cushioning airbag system includes a first airbag module, a second airbag module, a third airbag module, and a miniature air pump corresponding to each of the above airbag modules. The first airbag module is used to fit the user's temples on both sides, the second airbag module is used to fit the user's upper and lower eye sockets, and the third airbag module is used to fit the user's nose bridge. The first airbag module, the second airbag module, and the third airbag module can all be individually inflated and adjusted using their respective miniature air pumps.

[0013] As a further improvement of the present invention, a fan system is also provided in the VR glasses body and the head-mounted assembly. The fan system includes a first air outlet, a second air outlet and a corresponding micro fan assembly. There are two first air outlets, which are symmetrically arranged on both sides of the VR glasses body near the outer side of the lens assembly. The second air outlet is located on the side of the connecting part that is recessed inward.

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

[0015] 1. This head-mounted VR display device significantly enhances the user experience by integrating a control system, an advanced display system, and a unique airbag system within the VR glasses body. The display system employs a gap design between the front display screen and the rear lens assembly, optimizing visual immersion and image clarity. The airbag system includes an internal safety airbag system for protection against accidental impacts, and an external facial cushioning airbag system to enhance wearing comfort and sealing. The headband assembly's structural design not only stably supports the entire device but also integrates a detachable and replaceable headphone module, providing users with an immersive experience of synchronized audio and video.

[0016] 2. When the blocking airbag rolls in and out, the coordinated operation of the first and second air pumps enables automatic inflation and deflation of the airbag. When the user is no longer using the VR glasses, the blocking cover is activated via user command, causing the blocking airbag to inflate. The two protruding airbags on the side closest to the aspherical lens will precisely press against the two lens ends, tightly fitting the outer side of the aspherical lens, forming an effective dustproof and cushioning protective barrier. This not only effectively isolates dust, particles, and other impurities in the air, preventing them from adhering to the lens and affecting visual effects, but also prevents damage to the lens from prolonged exposure or external impacts, extending the lifespan of the VR glasses.

[0017] 3. With the airbag system in place, when the VR glasses are accidentally dropped, the built-in sensors can quickly respond and activate the airbag, causing it to pop out quickly from the tear and inflate into a concave airbag structure, effectively forming an all-around protective barrier. This 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 designing individual modules within the facial cushioning airbag system to fit the user's temples, eye sockets, and bridge of the nose, the system allows for personalized fit and inflation adjustments based on individual facial contours, resulting in optimal comfort. The airbag module design also reduces direct contact pressure between the VR headset and the user's face, providing cushioning and minimizing discomfort during extended wear, allowing 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 commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] Please see Figures 1 to 9 A head-mounted VR display device includes a VR glasses main body 10, a headband assembly 20, and an earphone module 30. The VR glasses main body 10 is equipped with a control system, a display system 40, and an airbag system 50. 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 main body 10, and the lens assembly 42 is located behind the display screen 41, forming a gap between them. The airbag system 50 includes a safety airbag system 51 and a face cushioning airbag system 52. The safety airbag system 51 is located inside the lower part of the VR glasses main body 10, and the face cushioning airbag system 52 is distributed on the inner side of the outside of the VR glasses main body 10. The headband assembly 20 is fixedly installed above the VR glasses main body 10 and is an elliptical frame. The earphone module 30 is located below the headband assembly 20.

[0033] Specifically, this head-mounted VR display device significantly enhances the user experience by integrating a control system, an advanced display system 40, and a unique airbag system 50 within the VR glasses main body 10. The display system 40 employs a gap design between the front display screen 41 and the rear lens assembly 42, optimizing 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. Furthermore, the structural design of the headband assembly 20 not only provides stable support for the entire device but also integrates an earphone module 30 below, enabling users to enjoy an immersive experience with synchronized audio and video.

[0034] like Figure 1-2 As shown, the head-mounted assembly 20 includes a connecting part 21, an adjusting part 22, and a head frame part 23. The head-mounted assembly 20 is fixedly connected to the VR glasses main body 10 through the connecting part 21, which is an inverted triangular connecting block. The adjusting part 22 is fixedly connected to the middle of the connecting part 21, and is an inverted U-shaped frame. The adjusting part 22 includes a fixing frame 220 and two telescopic frames 221. The fixing frame 220 is fixed to the middle of the connecting part 21 and extends to both sides. The fixing frame 220 has a fixing slot strip that cooperates with the telescopic frames 221. One end of each of the two telescopic frames 221 extends into the fixing frame 220 from both sides and connects to the fixing slot strip. The other ends of the two telescopic frames 221 are fixedly connected to both ends of the head frame part 23.

[0035] Specifically, the headband component 20 is securely connected to the VR glasses body 10 via an inverted triangular connecting part 21. The geometric characteristics of the inverted triangle provide connection strength in multiple directions, ensuring the overall stability of the device. The adjustment part 22, through the cooperation of the telescopic frame 221 and the fixing slot strip inside the fixing frame 220, allows users to freely adjust the tightness of the head frame 23 according to their head circumference, thereby achieving a personalized wearing experience. This not only improves wearing comfort but 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. A U-shaped groove 230 is provided on the lower side of the main body of the head frame 23. A rotating sub-frame 231 is provided inside the groove 230. Rotating shafts 232 are provided through both ends of the rotating sub-frame 231 near the two ends of the groove 230. The rotating sub-frame 231 is rotatably connected to the head frame 23 through the two rotating shafts 232. A pull handle 233 is provided 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 via rotating shafts 232 at both ends, and can be rotated by pulling the pull handle 233 in the middle. When not in use, the rotating sub-frame 231 can be compactly housed in the groove 230, maintaining the simplicity and aesthetics of the device; when worn, the user can easily pull the handle 233 to pull the rotating sub-frame 231 down to the neck, forming a stable support point, effectively preventing the VR device from shaking during intense gaming or prolonged wear, greatly enhancing the stability and comfort of wearing, and also adapting to the needs of different users. For example, when children wear it, because children's head circumference and neck size are relatively small, traditional VR devices often cannot provide a suitable fit and stability. The rotating sub-frame 231 design can be flexibly adjusted according to the size of a child's neck, ensuring a tight fit of the VR device and reducing light leakage and discomfort.

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

[0039] Specifically, by placing the earphone 31 below the head frame 23 and securing the earphone cable with three fasteners 32, a high degree of integration between the earphone and the VR glasses main body 10 is ensured. This not only allows the earphone 31 to fit snugly against the user's head, but also, through the stabilizing effect of the fasteners 32, effectively prevents the earphone 31 from shaking or falling off during wear, and avoids the cable from swinging and tangling during user activity, thereby ensuring the stability of sound transmission.

[0040] In one embodiment, the retaining clip 32 can be opened or closed, allowing users to easily open and remove the earphone 31. This makes the earphone module 30 highly adaptable, providing great convenience for users when they need to change to different models or styles of earphones to meet their individual needs. Furthermore, with continuous technological advancements and earphone upgrades, users can easily upgrade the earphone module 30 without replacing the entire VR headset, extending the lifespan of the VR headset device and reducing operating costs.

[0041] like Figure 3-5 As shown, the lens assembly 42 consists of two sets of aspherical lenses 420 and a lens shield 43. The shield 43 is located on the outside of the lens assembly 42, and a sliding track 430 is provided below the shield 43. The shield 43 is in the shape of a scroll and consists of a first rotating shaft 431, a second rotating shaft 432, and a shielding airbag 433. The shielding airbag 433 has two protruding airbags on the side near the aspherical lens 420, and 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 adjacent to the aspherical lens 420 on the right side. The upper and lower ends of the second rotating shaft 432 are provided with pulleys 434. The two pulleys 434 are respectively provided with traction shafts 435 on the upper and lower sides. The middle of the sliding track 430 is also provided with a transverse groove 436. The traction shaft 435 is inserted into the transverse groove 436 and is controlled by an electric motor to move left and right, and drives the second rotating shaft 432 to slide between the sliding tracks 430. The second rotating shaft 432 can rotate.

[0042] In one embodiment, the opening and closing process of the shield 43 can be automated. The roll shape of the shield 43 and the design of the sliding track 430 control the movement of the traction shaft 435 in the transverse groove 436 through electromechanical control, which drives the pulleys 434 at the upper and lower ends of the second rotating shaft 432 to slide in the sliding track 430. With the rotation function of the second rotating shaft 432, the shield 43 can move left and right in the transverse groove 436, and the shielding airbag 433 can roll up, contract or open accordingly.

[0043] like Figure 4-7As shown, the shielding airbag 433 is an airbag bag sealed on both the top and bottom sides, with air vents on the right side connected to the first rotating shaft 431 and the left side connected to the second rotating shaft 432. Both the first rotating shaft 431 and the second rotating shaft 432 are hollow cylinders. A first air pipe 437, penetrating the interior and extending to the right, is located in the middle of the first rotating shaft 431. A first air pump 438 is connected to the external interface of the first air pipe 437. The air vent 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. The second rotating shaft 432... The unit is provided with a second air pipe 439 that runs through the interior. The air vent on the left side of the airbag 433 is located 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 installed on one inner side wall of the VR glasses body 10. The second air pump 440 is located near the end of the sliding track 430 away from the first rotating shaft 431. A sealing tube 441 extends outward from the side of the second air pump 440 near the second rotating shaft 432. The sealing tube 441 is positioned opposite to the external interface of the second air pipe 439 and can extend into the interior of the second air pipe 439.

[0044] In one embodiment, when the blocking airbag 433 rolls in and out, the coordinated operation of the first air pump 438 and the second air pump 440 enables the automatic inflation and deflation of the blocking airbag 433. When the user is no longer using the VR glasses, the blocking cover 43 is activated by the user's command, causing the blocking airbag 433 to inflate. After inflation, the two protruding airbags on the side of the blocking airbag 433 closest to the aspherical lens 420 will precisely abut against the two lens ends, tightly fitting against the outer side of the aspherical lens 420, forming an effective dustproof and buffering protective barrier. This not only effectively isolates dust, particles, and other impurities in the air, preventing them from adhering to the lens and affecting the visual effect, but also prevents the lens from being damaged due to prolonged exposure or external impact, extending the service life of the VR glasses.

[0045] The airbag 433 includes an inflated state and an inflated state. In the inflated state, the first air pump 438 and the second air pump 440 evacuate the air from the airbag 433, and the airbag 433 is in a double-layered airbag fabric state. The airbag 433 can be rolled up and 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 airbag 433 opens accordingly. The external interface of the second air tube 440 is connected to the sealing tube 441. The first air pump 438 and the second air pump 439 inflate the airbag 433 through the first air tube 437 and the second air tube 439 respectively, so that the airbag 433 is in an inflated state.

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

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

[0048] ① User command trigger: When the user ends the VR experience and is about to put the glasses idle, the user can send a command to activate the mask 43 through the button on the VR glasses body 10, voice command or the accompanying application.

[0049] ② Electromechanical response: Upon receiving the command, the electromechanical system begins operation. The traction shaft 435 moves smoothly within 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 an inflated state, but it gradually unfolds as the second rotating shaft 432 moves.

[0050] ③ Airbag inflation preparation: When the second rotating shaft 432 slides to the preset position (usually the farthest side away from the first rotating shaft 431), the external interface of the second air tube 439 is engaged with the sealing tube 441. After the sealing tube 441 is inserted, it will completely seal the interface, ensuring the airtightness when the airbag is inflated.

[0051] ④ Collaborative operation of air pumps: The first air pump 438 and the second air pump 440 start simultaneously, inflating the shielding airbag 433 through the first air pipe 437 and the second air pipe 439 respectively. As the gas is injected, the shielding airbag 433 gradually expands and fits tightly against the outside of the aspherical lens 420, forming an effective dustproof and buffering protective barrier.

[0052] ⑤ Status Confirmation: After the airbag 433 has inflated, the system will confirm its status to ensure that the shield 43 has been correctly opened and has achieved the expected dustproof effect. At this time, the user can obtain relevant information through the indicator lights on the VR glasses main body 10, sound prompts, or the application interface.

[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 cover 43 is sent in a corresponding manner.

[0055] ② Air pump evacuation of the airbag: Upon receiving the instruction, the first air pump 438 and the second air pump 440 begin to operate, but this time they evacuate the gas inside the shielding airbag 433. As the gas is expelled, the shielding airbag 433 gradually contracts and becomes a close-fitting double-layered airbag fabric.

[0056] ③ Electromechanical response: As the airbag contracts, the electromechanical system is activated again, and the traction shaft 435 drives the second rotating shaft 432 to slide along the sliding track 430 towards the first rotating shaft 431. As the second rotating shaft 432 moves, the shielding airbag 433 is further rolled up and contracted.

[0057] ④ Status Confirmation: When the mask 43 is fully retracted and fitted onto the first hinge 431, the system will perform a status confirmation to ensure that the mask 43 is properly closed and ready for the next use. Similarly, users can obtain relevant information through indicator lights, sound prompts, or the application interface on the VR glasses main body 10.

[0058] like Figure 9 As shown, the airbag system 51 includes an airbag 510, a tear 511, and a sensor. The tear 511 is a sealed opening formed by a rectangular tear line. The tear 511 is located at the lower center of the VR glasses body 10. The airbag 510 is fully contracted and sealed inside the tear 511. When the VR glasses body 10 falls, the internal sensor will trigger the airbag 510 to expand. The airbag 510 will pop out from the tear 511 and collide to form a concave airbag. The concave airbag is used to wrap the VR glasses body 10. The concave airbag includes a bottom buffer part 512 and a surrounding part 513 around the edge of the bottom buffer part 512. The surrounding part 513 surrounds the periphery of the VR glasses body 10.

[0059] In one embodiment, the airbag system 51 is configured such that when the VR glasses are accidentally dropped, the built-in sensors can quickly respond and activate the airbag 510, causing it to rapidly eject from the tear 511 and inflate into a concave airbag structure. This concave airbag consists of a bottom cushioning portion 512 and a surrounding portion 513 that encircles the VR glasses body 10, effectively forming an all-around protective barrier. This 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. When not inactive, the airbag 510 is completely retracted and sealed inside the tear 511, without affecting the device's appearance. It provides protection when needed, and the design of the airbag 510 allows for replacement after damage, maintaining the device's protective function.

[0060] In another embodiment, whether the airbag system 51 is enabled can be selected and controlled by the user to avoid the ineffective application and destruction of the airbag 510 in some situations where the movement is more intense.

[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 miniature air pump corresponding to each of the above airbag modules. The first airbag module 520 is used to fit 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 user's nose bridge. The first airbag module 520, the second airbag module 521, and the third airbag module 522 can all be individually inflated and adjusted using their respective miniature air pumps.

[0062] In one embodiment, the modules of the facial cushioning airbag system 52 are respectively fitted to the user's temples, eye sockets, and bridge of the nose, allowing for personalized adaptation and inflation adjustment based on individual facial contours to achieve optimal comfort. The airbag module design reduces direct contact pressure between the VR glasses and the user's face, providing cushioning and reducing discomfort from prolonged wear, allowing the user to focus more on the virtual reality experience. Adjusting the inflation level of the airbags also ensures a close fit to the user's face, reducing light leakage and enhancing immersion. The facial cushioning airbag system 52 also absorbs external impacts, protecting the VR glasses body 10 and the user's face during use, preventing injuries from collisions that may occur while immersed in the VR experience.

[0063] The VR glasses main body 10 and headband component 20 are also equipped with a fan system 60. The fan system 60 includes a first air outlet 61, a second air outlet 62 and a corresponding micro fan component. There are two first air outlets 61, which are symmetrically arranged on both sides of the VR glasses main body 10 near the outer side of the lens component 42. The second air outlet 62 is located on the side of the connecting part 21 that is recessed inward.

[0064] In one embodiment, the fan system 60 facilitates airflow, improves thermal management and breathability, and reduces facial sweating and stuffiness. A pair of first air vents 61 are positioned near the outer side of the lens assembly 42, effectively accelerating airflow in the eye area and evenly dispersing heat and moisture from the outer side of the lens assembly 42, reducing stuffiness and fogging caused by prolonged wear and maintaining clear vision. The second air vent 62 is located on the concave side of the connection portion 21 of the headband assembly 20, further promoting air circulation around the head, reducing stuffiness, and enhancing overall heat dissipation. The fan system 60 improves the comfort and durability of the VR glasses and ensures a cool feel during extended use, significantly enhancing the overall user experience of the VR device. Furthermore, effective thermal management ensures that the electronic components of the VR device operate at suitable temperatures, thereby maintaining device performance and reducing performance degradation or device damage caused by overheating.

[0065] In another embodiment, the fan system 60 can also be used for periodic dust removal. By using a pair of first air outlets 61 located near the outer side of the lens assembly 42 to blow air onto the lens assembly 42, the airflow generated by the fan can remove dust from the VR glasses lens and interior, maintaining a clear field of vision.

[0066] This invention can achieve:

[0067] (1) This head-mounted VR display device significantly enhances the user experience by integrating the control system, advanced display system 40, and unique airbag system 50 within the VR glasses main body 10. The display system 40 employs a gap design between the front display screen 41 and the rear lens assembly 42, optimizing 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. Furthermore, the structural design of the headband assembly 20 not only provides stable support for the entire device but also integrates the headphone module 30 below, enabling users to enjoy an immersive experience with synchronized audio and video.

[0068] (2) When the blocking airbag 433 rolls in and out, in conjunction with the coordinated operation of the first air pump 438 and the second air pump 440, the blocking airbag 433 can be automatically inflated and deflated. When the user no longer uses the VR glasses, the blocking cover 43 is activated by the user's command, causing the blocking airbag 433 to inflate. After inflation, the two protruding airbags on the side of the blocking airbag 433 closest to the aspherical lens 420 will precisely abut against the two lens ends, tightly fitting the outer side of the aspherical lens 420, forming an effective dustproof and buffering protective barrier. This not only effectively isolates dust, particles and other impurities in the air, preventing them from adhering to the lens and affecting the visual effect, but also prevents the lens from being damaged due to prolonged exposure or external impact, thus extending the service life of the VR glasses.

[0069] (3) The airbag system 51 is designed so that when the VR glasses are accidentally dropped, the built-in sensors can quickly respond and activate the airbag 510, causing it to rapidly eject from the tear 511 and inflate into a concave airbag structure. This concave airbag consists of a bottom buffer 512 and a surrounding part 513 that surrounds the VR glasses body 10, effectively forming an all-around protective barrier. This 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 part 513, significantly improving the device's drop resistance and user safety. When not inactive, the airbag 510 is completely retracted and sealed inside the tear 511, without affecting the appearance of the device. At the same time, it can provide protection when needed, and the design of the airbag 510 allows for replacement after damage, maintaining the protective function of the device.

[0070] (4) The various modules in the facial cushioning airbag system 52 are respectively fitted to the user's temples, eye sockets, and bridge of the nose, allowing for personalized adaptation and inflation adjustment according to individual facial contours to achieve the best comfort experience. The design of the airbag modules reduces the direct contact pressure between the VR glasses and the user's face, providing cushioning and reducing discomfort from prolonged wear, allowing the user to focus more on the virtual reality experience. By adjusting the inflation level of the airbags, they can also be made to fit the user's face closely, reducing light leakage and enhancing immersion. The facial cushioning airbag system 52 can also absorb external impacts, protecting the VR glasses body 10 while also protecting the user's face during use, preventing injuries that may occur due to collisions in the environment while immersed in the VR experience.

[0071] (5) By setting up the fan system 60, air circulation is facilitated, heat management and breathability are improved, and facial sweating and stuffiness are reduced. The first air outlet 61 is arranged in pairs near the outer side of the lens assembly 42, which effectively accelerates air circulation in the eye area, can evenly disperse the heat and moisture on the outer side of the lens assembly 42, reduce stuffiness and fogging caused by prolonged wear, and maintain clear vision; the second air outlet 62 is placed on the concave side of the connection part 21 of the headband assembly 20, which further promotes the circulation of air around the head, reduces the stuffiness of the head, and enhances the overall heat dissipation effect. The fan system 60 improves the comfort and durability of VR glasses, and also ensures a cool feeling during long-term use, significantly enhancing the overall use effect of VR devices.

[0072] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
