Description

Technical Field

[0001] This invention relates to a VR device, and more particularly to a VR device with safety protection functions. Background Technology

[0002] Currently, VR glasses use head-mounted display devices to block out a person's vision and hearing from the outside world, guiding the user to feel as if they are in a virtual environment. The display principle is that the left and right eye screens display images for the left and right eyes respectively. After the human eye obtains this information with differences, it generates a sense of three-dimensionality in the brain.

[0003] If the game is too stimulating during the experience of existing VR virtual reality devices, it can easily make the user addicted. This can cause the user to be startled and overreact, resulting in loss of balance and falls. However, existing VR virtual reality devices generally do not have specific protective facilities. Staff members are usually present to protect the user or add soft padding to prevent the user from getting hurt. Moreover, the staff members have limited reaction speed and cannot protect the user in time, resulting in low safety.

[0004] Given the limited reaction speed of staff, making it difficult to protect users in a timely manner and resulting in low safety, there is an urgent need for a VR device with high safety protection functions to solve the above problems. Summary of the Invention

[0005] To overcome the shortcomings of limited reaction speed of staff, difficulty in protecting users in the first instance, and low safety, the purpose of this invention is to provide a VR device with high safety and safety protection functions.

[0006] This invention is achieved through the following technical means:

A first elastic element is wound around the first connecting rod, and the two ends of the first elastic element are connected to the first toothed block and the connecting plate, respectively. Second toothed blocks are evenly spaced on the outer side of the rotating ring. The first fixed block can limit the movement of the second toothed blocks.

[0009] Furthermore, the fixing mechanism includes a safety harness, a first buckle, and a second buckle. The lower end of the safety harness is connected to the safety harness. Three first buckles are evenly spaced on the lower left side of the safety harness, and three second buckles are evenly spaced on the lower right side of the safety harness. The first buckles engage with the second buckles.

[0010] Furthermore, it also includes a protective mechanism for protecting people's heads. The protective mechanism includes a second fixing block, a third fixing block, a first connecting pipe, a second connecting pipe, a placement block, an airbag, and a valve. The second fixing block is connected to the upper rear side of the VR device. The third fixing blocks are symmetrically connected to the upper and lower rear side of the VR device. The first connecting pipe is connected to the second fixing block. Both ends of the first connecting pipe pass through the two third fixing blocks. One end of the first connecting pipe is connected to and communicates with the top of the compressed air tank. Placement blocks are connected to the lower left and right sides of the VR device. An airbag is installed in each of the two placement blocks. The second connecting pipe is connected to the lower rear side of the VR device. The other end of the first connecting pipe is connected to and communicates with the middle of the top of the second connecting pipe. The left and right sides of the second connecting pipe are respectively connected to and communicate with the rear of the left and right airbags. A valve is connected to the upper part of the first connecting pipe.

[0011] Furthermore, it also includes a triggering mechanism for triggering the compressed gas tank. The triggering mechanism includes a slide rail, a rack, a second connecting rod, a second elastic element, and a wedge block. The upper right side of the VR device is connected to the slide rail, and the lower part of the slide rail is slidably equipped with a rack. The second tooth block meshes with the rack. The upper right side of the VR device is connected to the second connecting rod, and the second connecting rod is slidably connected to the rack. The second elastic element is wound around the second connecting rod, and the two ends of the second elastic element are respectively connected to the second connecting rod and the rack. The bottom rear side of the rack is connected to a wedge block, and the wedge block will contact the valve when it moves forward.

[0012] Furthermore, it also includes an air delivery mechanism for recycling compressed air. The air delivery mechanism includes an air pump, a first delivery pipe, and a second delivery pipe. The air pump is connected to the rear side of the compressed air tank. The first delivery pipe is connected to the rear side of the air pump and is in communication with it.

[0014] Furthermore, it also includes a warning mechanism for reminding users. The warning mechanism includes a second connecting block, a magnet, and a warning device. Four second connecting blocks are evenly spaced on the lower inner side of the VR device. Magnets are connected to the inner side of each of the four second connecting blocks. Warning devices are set on the inner side of each of the four magnets. The magnets attract the warning devices.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. When people fall, the seat belt will be pulled down quickly, causing the first toothed block to rotate rapidly. Under the action of centrifugal force, the first toothed block will move outward and lock the ratchet, thereby driving the ratchet and the second toothed block to rotate. The first fixing block can limit the second toothed block, and thus the seat belt can pull people's bodies to prevent them from falling, which is highly safe.

[0017] 2. The forward movement of the wedge block in this invention triggers a valve, allowing gas from the compressed gas tank to enter the airbag, thereby inflating the airbag and preventing people's heads from hitting the railing of the VR device.

[0018] 3. When people move to the edge of the VR device, the alarm will sound to warn them and prevent them from bumping into the VR device's railing. Attached Figure Description

Detailed Implementation

[0030] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] A VR device with safety protection features, see [link / reference] Figures 1-6 As shown, it includes a VR device 1, a compressed air tank 2, an adjustment mechanism 3, and a fixing mechanism 4. The compressed air tank 2 is connected to the lower rear side of the VR device 1. The compressed air tank 2 is filled with compressed air. The adjustment mechanism 3 is set on the upper part of the VR device 1, and the fixing mechanism 4 is set on the adjustment mechanism 3.

[0033] See Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the adjustment mechanism 3 includes a mounting block 31, a rotating shaft 32, a first fixing block 33, a safety belt 34, a first spiral spring 35, a rotating ring 36, a ratchet 37, a connecting plate 38, a first connecting rod 39, a first toothed block 310, a first elastic element 311, and a second toothed block 312. The mounting block 31 is welded to the upper part of the VR device 1. A rotating shaft 32 is rotatably mounted in the middle of the mounting block 31. The first fixing block 33 is connected to the upper part of the VR device 1 and is rotatably connected to the rotating shaft 32. A safety belt 34 is wound around the middle of the rotating shaft 32 to hold people's bodies and prevent them from falling. A first spiral spring 35 is wound around the left side of the rotating shaft 32. Both ends are connected to the rotating shaft 32 and the mounting block 31 respectively. A rotating ring 36 is rotatably provided on the inner side of the first fixing block 33. A ratchet 37 is connected to the left side of the rotating ring 36. A connecting plate 38 is connected to the right side of the rotating shaft 32. A first connecting rod 39 is welded to the right side of the connecting plate 38. A first tooth block 310 is slidably provided at the rear of the first connecting rod 39. When the first tooth block 310 moves outward, it will mesh with the ratchet 37. A first elastic element 311 is wound around the first connecting rod 39. Both ends of the first elastic element 311 are connected to the first tooth block 310 and the connecting plate 38 respectively. Second tooth blocks 312 are evenly spaced on the outer side of the rotating ring 36. The first fixing block 33 can limit the second tooth blocks 312.

[0034] See Figure 1 and Figure 6 As shown, the fixing mechanism 4 includes a safety strap 41, a first buckle 42, and a second buckle 43. The safety strap 41 is welded to the lower end of the safety belt 34. People wear the safety strap 41 for protection. Three first buckles 42 are evenly spaced on the lower left side of the safety strap 41, and three second buckles 43 are evenly spaced on the lower right side of the safety strap 41. The first buckles 42 lock the second buckles 43.

[0035] When the device is needed, people first place it in the designated location, then walk onto the VR device 1, and pull the first buckle 42 out of the second buckle 43, so that the first buckle 42 is no longer locked to the second buckle 43. Then, people put on the safety harness 41, and then lock the first buckle 42 back into the second buckle 43 to secure the safety harness 41. Then, people can start the VR device 1 to experience it. When people walk, the safety belt 34 will move up and down adaptively, and the first spiral spring 35 will move up and down accordingly. The seat belt 34 deforms responsively when people fall, pulling the seat belt 34 downwards quickly, causing the rotating shaft 32 to rotate rapidly in the forward direction. The first spiral spring 35 deforms, and the rotation of the rotating shaft 32 causes the connecting plate 38, the first connecting rod 39, the first toothed block 310, and the first elastic element 311 to rotate rapidly in the forward direction. Under the action of centrifugal force, the first toothed block 310 moves outwards, and the first elastic element 311 stretches, causing the first toothed block 310 to engage with the ratchet 37. At this time, the first toothed block 310 drives the ratchet 37 to rotate in the forward direction, and the rotation of the ratchet 37 drives the rotating ring 36 to rotate in the forward direction. When the rotating ring 36 rotates clockwise, it drives the second toothed block 312 to rotate clockwise. When the first fixed block 33 engages the second toothed block 312, the second toothed block 312 stops rotating clockwise, causing the rotating ring 36 and ratchet 37 to stop rotating clockwise. This, in turn, stops the first toothed block 310 and the rotating shaft 32 from rotating clockwise, allowing the safety belt 34 to hold the person's body and prevent them from falling. After the person has stabilized, the first spiral spring 35 returns to its original position, driving the rotating shaft 32 to rotate counterclockwise and rewind the safety belt 34. The counterclockwise rotation of the rotating shaft 32 drives the connecting plate 38, the first connecting rod 39, and the first... The toothed block 310 and the first elastic element 311 reverse. The reversal of the first toothed block 310 drives the ratchet 37, the rotating ring 36 and the second toothed block 312 to reverse and reset. At the same time, the first elastic element 311 returns to its original state, driving the first toothed block 310 to move inward and reset, so that the first toothed block 310 separates from the ratchet 37. After the experience is over, people turn off the VR device 1, then pull the first buckle 42 out of the second buckle 43 so that the first buckle 42 no longer locks the second buckle 43. Then they can take off the glasses and safety strap 41 and leave the VR device 1.

[0036] Example 2

[0037] Based on Example 1, see [link to Example 1] Figure 1 , Figure 3 and Figure 7As shown, it also includes a protection mechanism 5, which includes a second fixing block 51, a third fixing block 52, a first connecting pipe 53, a second connecting pipe 54, a placement block 55, a safety airbag 56, and a valve 57. The second fixing block 51 is welded to the upper rear side of the VR device 1, and the third fixing blocks 52 are symmetrically welded to the upper and lower rear side of the VR device 1. The first connecting pipe 53 is connected to the second fixing block 51, and both ends of the first connecting pipe 53 pass through the two third fixing blocks 52. One end of the first connecting pipe 53 is connected to the top of the compressed air tank 2. The VR device 1 is connected and interconnected. Placement blocks 55 are connected to the lower left and right sides of the VR device 1. Safety airbags 56 are installed in both placement blocks 55. The inflated safety airbags 56 can prevent people's heads from hitting the railings of the VR device 1. The lower rear side of the VR device 1 is connected to a second connecting pipe 54. The other end of the first connecting pipe 53 is connected and interconnected to the middle of the top of the second connecting pipe 54. The left and right sides of the second connecting pipe 54 are respectively connected and interconnected to the rear of the safety airbags 56 on the left and right sides. A valve 57 is connected to the upper part of the first connecting pipe 53.

[0038] See Figure 3 and Figure 8 As shown, it also includes a triggering mechanism 6, which includes a slide rail 61, a rack 62, a second connecting rod 65, a second elastic element 66, and a wedge block 67. The slide rail 61 is connected to the upper right side of the VR device 1, and the rack 62 is slidably arranged at the lower part of the slide rail 61. The second tooth block 312 meshes with the rack 62. The second connecting rod 65 is connected to the upper right side of the VR device 1, and the second connecting rod 65 is slidably connected to the rack 62. The second elastic element 66 is wound around the second connecting rod 65, and the two ends of the second elastic element 66 are respectively connected to the second connecting rod 65 and the rack 62. The wedge block 67 is welded to the rear side of the bottom of the rack 62. When the wedge block 67 moves forward, it will contact the valve 57. When the wedge block 67 moves forward, it will squeeze the valve 57 to open, so that the gas in the compressed air tank 2 enters the airbag 56.

[0039] See Figure 1 and Figure 9 As shown, it also includes a gas delivery mechanism 7, which includes a vacuum pump 71, a first delivery pipe 72, and a second delivery pipe 73. The vacuum pump 71 is welded to the rear side of the compressed air tank 2. The vacuum pump 71 can deliver the gas in the airbag 56 to the compressed air tank 2, thereby enabling the gas in the compressed air tank 2 to be recycled. The rear side of the vacuum pump 71 is connected to and connected to the first delivery pipe 72. The upper end of the first delivery pipe 72 is connected to and connected to the second connecting pipe 54. The front side of the vacuum pump 71 is connected to and connected to the second delivery pipe 73. The front end of the second delivery pipe 73 is connected to and connected to the compressed air tank 2.

[0040] Initially, the compressed air tank 2 is filled with compressed air. When the second toothed block 312 rotates clockwise, it drives the rack 62 to move forward. The slide rail 61 acts as a guide. The forward movement of the rack 62 drives the wedge block 67 to move forward, stretching the second elastic element 66. When the wedge block 67 contacts the valve 57, the wedge block 67 squeezes the valve 57 to open, allowing the gas in the compressed air tank 2 to enter the second connecting pipe 54 through the first connecting pipe 53, and then enter the airbag 56 through the second connecting pipe 54, thereby inflating the airbag 56. The airbag 56 prevents people's heads from hitting the railing of the VR device 1. When the second toothed block... When 312 reverses, it drives the rack 62 to move backward, thereby driving the wedge block 67 to move backward and reset. The second elastic element 66 returns to its original state, assisting the rack 62 and wedge block 67 to move backward and reset, so that the wedge block 67 releases the valve 57, and the gas in the compressed air tank 2 no longer enters the airbag 56. At this time, people can start the vacuum pump 71, which can extract the gas in the airbag 56, so that the gas in the airbag 56 returns to the compressed air tank 2 through the first delivery pipe 72 and the second delivery pipe 73. When all the gas in the airbag 56 has been extracted, people can turn off the vacuum pump 71, so that the gas in the compressed air tank 2 can be recycled.

[0041] See Figure 1 and Figure 10 As shown, it also includes a covering mechanism 8, which includes a first connecting block 81, a cover plate 82, and a second spiral spring 83. The VR device 1 has first connecting blocks 81 welded to both the left and right sides of the lower part. The cover plate 82 is rotatably mounted on the upper part of the two first connecting blocks 81. The cover plate 82 covers the placement block 55. The cover plate 82 can cover the airbag 56 when it moves inward, so that the airbag 56 can be retracted. The cover plate 82 and the first connecting block 81 are symmetrically connected to each other with the second spiral spring 83.

[0042] When the airbag 56 inflates, it will rotate the cover plate 82 outward and open it. The second spiral spring 83 will deform. When the gas in the airbag 56 returns to the compressed air tank 2, the airbag 56 will no longer press against the cover plate 82. The second spiral spring 83 will return to its original shape, which will drive the cover plate 82 to move inward and close it, so that the cover plate 82 covers the airbag 56, thereby enabling the airbag 56 to retract.

[0043] See Figure 1 and Figure 10As shown, it also includes a warning mechanism 9, which includes a second connecting block 92, a magnet 91, and a warning device 93. When people move to the edge of the VR device 1, the warning device 93 will sound an alarm to prevent people from bumping into the railing of the VR device 1. Four second connecting blocks 92 are evenly spaced welded to the lower inner side of the VR device 1. Magnets 91 are connected to the inner side of each of the four second connecting blocks 92. Warning devices 93 are set on the inner side of each of the four magnets 91. The magnets 91 attract the warning devices 93.

[0044] When people move to the edge of VR device 1, the alarm 93 will sound an alarm to warn them and prevent them from bumping into the railing of VR device 1. When people move away from the edge, the alarm 93 will stop sounding. When the alarm 93 needs to be repaired or replaced, people can remove the alarm 93 to separate it from the magnet 91, and then place the repaired or new alarm 93 on the second connecting block 92 so that the magnet 91 can re-attach the alarm 93.
