Virtual reality technology includes computer, electronic information and simulation technology, and its basic implementation method is to simulate a virtual environment by computer to give people a sense of environmental immersion. With the continuous development of social productive forces and scientific technology, the demand for VR technology in various industries is increasing. Especially in earthquake rescue training, it is difficult to fully simulate the emergency situation during an earthquake by imagination alone. At this time, the virtual reality device can make people feel as if they were there, and improve the authenticity of rescue training.

[0003] The existing application of virtual reality devices in earthquake rescue mostly adopts the method of wearing VR glasses, which simulates the scene during an earthquake by playing pictures on the VR glasses, and switches the picture effect according to the actions of the training personnel to achieve the purpose of training people's emergency rescue ability.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figures 1-8The illustration shows the application of a virtual reality device in earthquake rescue, including a helmet 1, VR glasses 2, a wearing mechanism 5, a massage mechanism 8, and an auxiliary mechanism 11. The helmet 1 has fixed shafts 3 on both sides, and a flip cover 4 is rotatably connected to the fixed shafts 3. The flip cover 4 is made of a semi-transparent material, and the VR glasses 2 are mounted on the flip cover 4. The wearing mechanism 5 includes an inflation / deflation pump 6 fixedly mounted on the flip cover 4. The flip cover 4 has a connector 7 for connecting to the VR glasses 2. The wearing mechanism 5 inflates the connector 7 using the inflation / deflation pump 6, allowing the VR glasses 2 to slowly... The massage mechanism 8 includes two sets of elastic bladders 9 fixedly installed on the VR glasses 2, with massage heads 10 slidably connected inside each set of elastic bladders 9. The massage mechanism 8 is used to rotate the massage heads 10 in conjunction with the operation of the inflation / deflation machine 6, thereby massaging the area around the eyes while keeping them close to and away from the eyes, relieving discomfort caused by prolonged wear. The auxiliary mechanism 11 includes two sets of earphone covers 12 installed inside the helmet 1. The auxiliary mechanism 11 is used to adjust the position of the earphone covers 12 in conjunction with the operation of the inflation / deflation machine 6, so that the earphone covers 12 can automatically adapt to the user's ears and move.

[0034] Please see Figures 1-10 The training method for using the virtual reality device shown in the illustration in earthquake rescue includes the following steps:

[0035] S1. Wearing: Lift the flip cover 4, put the helmet 1 on your head, then flip the flip cover 4 down so that the VR glasses 2 are in front of the trainee's eyes. Start the inflation and deflation machine 6, which will drive the connector 7 to move, so that the VR glasses 2 and the headphone cover 12 move inward in sync until they fit the trainee's eyes and ears, thus completing the wearing process.

[0036] S2. Training: When the inflation / deflation machine 6 is running, it can be linked to the operation of the massage mechanism 8, so that the massage head 10 can rotate and massage around the eye socket. At the same time, it can assist in relaxing the eyes during training and deliver excess air into the helmet 1 to avoid excessive stuffiness inside the helmet 1 during training.

[0037] S3. End: Start the inflation / deflation machine 6 to evacuate air, so that the VR glasses 2 and the headphone cover 12 gradually move away from the trainee. At the same time, the flip cover 4 in front of the eyes blocks the light to a certain extent, effectively avoiding the discomfort caused by the sudden strong light interference from the outside world when the training ends. Then, slowly lift the flip cover 4 and remove the helmet 1 to complete the training.

[0038] In this implementation, the flip cover 4 is made of a semi-transparent material, which can block some of the strong light in front of the eyes when it is closed. Lifting the flip cover 4, the helmet 1 is put on the head, and then the flip cover 4 is flipped downwards to move the VR glasses 2 to the front of the trainee's eyes. Activating the inflation / deflation mechanism 6 will drive the connecting piece 7, causing the VR glasses 2 and the headphone cover 12 to gradually move inwards until they fit the trainee's eyes and ears, thus completing the wearing process. While the inflation / deflation mechanism 6 is running, it can also activate the massage mechanism 8, causing the massage heads 10 to rotate and massage around the eye sockets, simultaneously assisting in eye relaxation during training. Excess gas is pumped into the helmet 1 to prevent excessive heat buildup during training. The inflation / deflation machine 6 is then activated to extract air, causing the VR glasses 2 and headphone cover 12 to gradually move away from the trainee. Simultaneously, the flip cover 4 in front of the eyes provides some light blocking, effectively preventing eye discomfort caused by sudden strong external light interference at the end of training. Afterward, the flip cover 4 is slowly lifted, and the helmet 1 is removed to complete the training. This device has a simple structure, is highly efficient and convenient to operate, and can be worn stably, preventing the VR glasses 2 from falling off due to violent shaking during simulated earthquake rescue training, making the use process more comfortable.

[0039] Example 2

[0040] Please see Figures 2-6 Example 2 is described below. This example further illustrates Example 1. The connector 7 shown in the figure includes a fixed tube 13 fixedly installed on the flip cover 4. A sliding column 14 is slidably connected inside the fixed tube 13. One end of the sliding column 14 is fixedly connected to the VR glasses 2. A tension spring 15 is fixedly connected to the side of the sliding column 14 and is fixedly connected to the inner wall of the fixed tube 13. The output end of the inflation / deflation machine 6 is connected to a connecting tube 16 that is connected to the fixed tube 13. Two imaging devices 41 are provided on the VR glasses 2. The two imaging devices 41 are located in the middle of the elastic bladders 9 on both sides.

[0041] Please see Figures 1-6 The auxiliary mechanism 11 shown in the figure also includes guide tubes 37 fixedly installed on both sides inside the helmet 1. One end of the guide tube 37 passes through the helmet 1 and the fixed shaft 3 and is connected to the output end of the inflator 6. A guide rod 38 is fixedly connected to the side of the earphone cover 12. The guide rod 38 is slidably connected to the inner wall of the guide tube 37 in the horizontal direction. The wearing mechanism 5 also includes two sets of straps 39 fixedly installed on both sides of the helmet 1. The helmet 1 has a groove 40 that is slidably connected to the outer wall of the fixed tube 13.

[0042] In this embodiment, rotating the flip cover 4 will cause the fixing tube 13 and sliding column 14 to rotate and flip together, and the VR glasses 2 will be inflated by the air inflator 6, which will cause the connecting tube 16 to inflate the fixing tube 13. The air pressure in the fixing tube 13 will increase, causing the VR glasses 2 to gradually move closer to the eyes, and the tension spring 15 will be stretched. At the same time, the air inflator 6 will inflate the guide tube 37, which will push the guide rod 38, and the earphone cover 12 will gradually fit to the ear side, completing the wearing of the earphone cover 12. Conversely, when the air inflator 6 deflates, the air pressure in the fixing tube 13 and guide tube 37 will decrease, and the VR glasses 2 and earphone cover 12 will move away from the head side at the same time. The strap 39 can more stably fit and fix the helmet 1 to the trainee's head, avoiding the situation where the VR glasses 2 will fall off due to violent shaking during simulated earthquake rescue training.

[0043] Example 3

[0044] Please see Figures 2-10 Example 3 further illustrates Example 1. The massage mechanism 8 shown in the figure also includes two sets of arc-shaped plates 17 fixedly installed inside the VR glasses 2. A drive disk 18 is rotatably connected inside the VR glasses 2. A transmission belt 19 is driven to the outer wall of the drive disk 18. The inner wall of the transmission belt 19 is slidably connected to the outer wall of the arc-shaped plate 17. The VR glasses 2 is provided with a drive component 20 for rotating the drive disk 18 in conjunction with the operation of the air pump 6. A rotating component 21 is provided on the transmission belt 19 for driving the massage head 10 to rotate synchronously.

[0045] Please see Figures 4-10 The driving component 20 shown in the figure includes two sets of fixed boxes 22 fixedly installed inside the VR glasses 2. A rotating shaft 23 is rotatably connected to a non-central position inside the fixed box 22. One end of the rotating shaft 23 passes through the fixed box 22 and is coaxially fixedly connected to the driving disk 18. A rotating disk 24 is coaxially fixedly connected to the rotating shaft 23. Multiple sets of sliding grooves 25 are evenly opened on the rotating disk 24. A driving plate 26 is slidably connected inside the sliding groove 25. A second spring 27 is fixedly connected to one end of the driving plate 26 and is fixedly connected to the sliding groove 25. The end of the driving plate 26 away from the second spring 27 slides against the inner wall of the fixed box 22. The VR glasses 2 is provided with a conveying component 28 for conveying gas in the fixed tube 13.

[0046] Please see Figures 6-10The conveying component 28 shown in the figure includes a first pipe 29 and a second pipe 30 fixedly installed between the two fixed boxes 22. The first pipe 29 and the second pipe 30 are respectively connected to the two fixed boxes 22. An input pipe 31 is connected to the first pipe 29. The input pipe 31 passes through the sliding column 14 and is connected to the fixed pipe 13. An output pipe 32 is connected to the second pipe 30. An exhaust hood 33 for uniformly discharging the gas in the output pipe 32 into the helmet 1 is fixedly connected to the VR glasses 2. The rotating component 21 includes multiple sets of fixed rings 34 uniformly fixedly installed on the outer wall of the transmission belt 19. A sliding rod 35 fixedly connected to the massage head 10 is slidably connected to the inner wall of the fixed ring 34. A first spring 36 fixedly connected to the fixed ring 34 is fixedly connected to one side of the massage head 10.

[0047] In this embodiment, when the inflation / deflation machine 6 inflates the fixed tube 13, the gas is input into the first pipe 29 through the input pipe 31, and then enters the fixed box 22 through the first pipe 29. This pushes the internal drive plate 26, causing the rotating disk 24 to rotate. Gas is continuously transported unidirectionally through the first pipe 29 to the second pipe 30, which in turn drives the rotating shaft 23 to rotate. The rotating shaft 23 drives the drive disk 18 to rotate, thereby causing the transmission belt 19 to rotate. The transmission belt 19 drives the fixed ring 34, causing the sliding rod 35 to rotate accordingly. The massage head 10 rotates continuously, and one end of the massage head 10 lifts the elastic bladder 9 and pushes it towards the eye socket. The first spring 3... The 6 allows the massage head 10 to be cushioned after contact with the eye socket. The gas in the second pipe 30 is continuously discharged through the output pipe 32 and blown towards the trainee's head through the exhaust hood 33, avoiding the head stuffiness and discomfort during long-term wear. At the same time, the rotation speed of the massage head 10 and the exhaust speed of the exhaust hood 33 can be controlled by the inflation speed of the inflation machine 6. After use, the inflation machine 6 is started to evacuate the air, and the gas flows back into the fixing box 22 through the second pipe 30 and is output into the first pipe 29. At this time, the massage head 10 rotates in the opposite direction, massaging the eye socket while the sliding column 14 gradually moves the VR glasses 2 away from the eyes.
