Virtual reality is the ultimate application form of multimedia technology, which is the crystallization of the rapid development of computer software and hardware technology, sensing technology, robotics, artificial intelligence, behavioral psychology and other scientific fields. It mainly depends on the development of a number of key technologies such as three-dimensional real-time graphics display, three-dimensional positioning and tracking, tactile and olfactory sensing technology, artificial intelligence technology, high-speed computing and parallel computing technology, and the research of human behavior science. VR can also be applied to the training of scenario dialogue.

[0017] Another technical solution proposed by the present invention: Provide an implementation method of a Korean learning training device for VR scenario dialogue practice, including the following steps:

[0018] S1: Wear this device on the trainee's head through a connecting elastic band, pull the fitting arc-shaped block down, and the flip airbag will be inflated and expanded, so that the flip airbag changes from a horizontal state to a vertical state, protecting the trainee's neck position. The trainee conducts a scenario dialogue through the VR function module and the VR main body;

[0019] S2: When the trainee conducts Korean training, the fitting arc-shaped block descends. At this time, the temperature sensing module works to sense the temperature of the trainee's head wearing this device. When the head temperature is too low, it causes the driven hot air to blow out from multiple air outlet holes, avoiding direct blowing of the hot air to scald the head. When the head temperature is too high, it drives the blower fan to rotate and blow out cool air;

[0020] S3: When the trainee conducts a scenario dialogue, rotate the combined electronic mechanism to align the camera component with the trainee's mouth, and record the mouth shape and pronunciation during Korean training by taking pictures. After the combined electronic mechanism finishes taking pictures, watch the stored video. Thus, all implementation steps are completed.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. A Korean learning and training device and method based on VR scenario dialogue practice provided by the present invention. When Korean learning and training are required, through the elasticity of the connecting elastic band, this device is worn on the trainee's head, and the fitting arc-shaped block is pulled down. That is, at this time, the connecting block drives the piston to descend. The descent of the piston will squeeze the air inside the air cylinder, so that the air inside the air cylinder enters the flip airbag through the connecting hose. At this time, the flip airbag will be inflated and expanded. The state of the flip airbag is changed through the first hinge, so that the flip airbag changes from a horizontal state to a vertical state, protecting the trainee's neck position. The trainee conducts a scenario dialogue through the VR function module and the VR main body. The setting of the flip airbag allows the trainee to lie down comfortably to receive training. Then pull the fitting arc-shaped block up. The fitting arc-shaped block drives the connecting block and the piston to rise. At this time, the air inside the flip airbag is sucked, and the flip airbag shrinks, avoiding excessive floor area.

[0023] 2. A Korean learning and training device and method for VR scenario dialogue practice provided by the present invention. When the trainee conducts Korean training, the fitting arc-shaped block descends, which will drive the rotation of the first linkage wheel, the second linkage wheel, the third linkage wheel and the fourth linkage wheel, that is, drive the moving bar and the electrical block to move until the electrical block contacts the contact switch. At this time, the temperature sensing module starts to work, sensing the head temperature of the trainee wearing this device. When the head temperature is too low, the electric heating module starts to work, causing the heating element to start heating, and then the power drive module starts to work, driving the blower fan to rotate, so that the hot air driven passes through the through hole, the communication air outlet and the arc-shaped air supply cavity, and finally blows out from multiple air outlet holes, avoiding direct blowing of the hot air to scald the head. When the head temperature is too high, only the power drive module starts to work, driving the blower fan to rotate to blow out cool air. When the electrical block and the contact switch are no longer in contact, the temperature sensing module, the electric heating module and the power drive module stop working.

[0024] 3. A Korean learning and training device and method for VR scenario dialogue practice provided by the present invention. When the trainee conducts a scenario dialogue, the first folding plate and the second folding plate embedded in the VR main body are separated. Since the screw passes through the fixing block and is embedded in the limiting groove, the combined electronic mechanism is initially fixed at the lower end of the VR main body by two screws. At this time, the combined electronic mechanism can rotate, so that the camera assembly is aligned with the trainee's mouth to record the mouth shape and pronunciation during Korean training by taking pictures. When the combined electronic mechanism rotates to the required angle, turn the tightening assembly so that the threaded column passes through the threaded through groove and is threadedly connected to the threaded groove inside. At this time, one end of the screw is embedded in the fitting groove until the tightening assembly contacts and abuts against one side of the fixing block to fix the angular position of the combined electronic mechanism. When the combined electronic mechanism has finished taking pictures and needs to view the stored video, loosen the tightening assembly, separate the screw and the limiting groove, that is, remove the combined electronic mechanism. By folding the second folding plate and the first folding plate on one side of the combined electronic mechanism, pull out the support plate until the sliding rotating shaft is located inside the fitting rotating groove, and rotate the support plate to make it abut against one side of the combined electronic mechanism, that is, make the combined electronic mechanism placed obliquely, which is convenient for the trainee to view the video.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] In order to solve the technical problem that in the use of traditional VR scenario dialogue practice devices, namely VR helmets, it is not convenient to set a protection device on the neck of the trainee to protect the neck position, improve the use comfort of the trainee, and accelerate the language learning rate, as Figures 2 - 4 shown, the following preferred technical solutions are provided:

[0039] A Korean learning and training device and method for VR scenario dialogue practice, including a VR main body 1 and a head-mounted earphone 4 arranged on one side of the VR main body 1. A posterior brain fitting mechanism 6 is arranged on one side of the head-mounted earphone 4. A connecting elastic band 5 is arranged between the posterior brain fitting mechanism 6 and the connecting elastic band 5, and multiple groups of connecting elastic bands 5 are arranged. The posterior brain fitting mechanism 6, the head-mounted earphone 4 and the VR main body 1 are connected by multiple groups of connecting elastic bands 5. A fixing block 2 and a combined electronic mechanism 3 are arranged at the lower end of the VR main body 1, and the combined electronic mechanism 3 is movably arranged at the lower end of the VR main body 1 through the fixing block 2. The posterior brain fitting mechanism 6 includes a fitting block 61 and a fitting airbag 62 arranged on one side of the fitting block 61. An embedded arc block 63 is embedded in the fitting block 61. A flipping airbag 64 is arranged at the lower end of the embedded arc block 63. A first hinge 641 is arranged at the upper end of the flipping airbag 64, and two groups of first hinges 641 are arranged. The flipping airbag 64 is movably connected to the embedded arc block 63 through two groups of first hinges 641. A communication groove 642 is also opened at the upper end of the flipping airbag 64. Inflation components 631 are arranged on both sides of the embedded arc block 63. The inflation component 631 includes a connecting block 6311 arranged on one side of the embedded arc block 63 and an air cylinder 6313 arranged at the upper end inside the fitting block 61. A piston 6312 is embedded in the air cylinder 6313, and one end of the piston 6312 is connected to the connecting block 6311. One end of the air cylinder 6313 is provided with a communication hose 6314, and one end of the communication hose 6314 is connected to the flipping airbag 64 through the communication groove 642. A linkage component 632 is also meshed on one side of the embedded arc block 63. The linkage component 632 is arranged inside the fitting block 61. A microcomputer control module 7 and a VR function module 8 are arranged inside the VR main body 1. The VR function module 8 is electrically connected to a temperature sensing module 81, a camera retention module 82 and a voice storage module 83. The temperature sensing module 81 is arranged inside the fitting block 61. The camera retention module 82 and the voice storage module 83 are arranged inside the combined electronic mechanism 3. The temperature sensing module 81 is electrically connected to an electric heating module 811 and a power drive module 812.

[0040] Specifically, when Korean language learning training is required, the device is worn on the head of the trainee through the elasticity of the connecting elastic band 5, and the fitting arc block 63 is pulled down. At this time, the connecting block 6311 drives the piston 6312 to descend. The descent of the piston 6312 will squeeze the air inside the air cylinder 6313, so that the air inside the air cylinder 6313 enters the flipping airbag 64 through the connecting hose 6314. At this time, the flipping airbag 64 will be inflated and expanded. The state of the flipping airbag 64 is changed through the first hinge 641, so that the flipping airbag 64 changes from a horizontal state to a vertical state to protect the neck position of the trainee. The trainee conducts a scenario dialogue through the VR function module 8 and the VR main body 1. The setting of the flipping airbag 64 enables the trainee to lie down more comfortably to receive training. Then, the fitting arc block 63 is pulled up, and the fitting arc block 63 drives the connecting block 6311 and the piston 6312 to rise. At this time, the air inside the flipping airbag 64 is sucked, and the flipping airbag 64 shrinks, avoiding excessive floor area.

[0041] In order to solve the technical problem that the traditional VR scenario dialogue practice device is not convenient to adjust the wind force of the trainee according to the head temperature of the trainee, to avoid the trainee being impatient due to external factors and reducing the learning rate, as Figures 5 - 7 shown, the following preferred technical solutions are provided:

[0042] The linkage component 632 includes a first linkage wheel 6321 meshed on one side of the fitting arc block 63. A second linkage wheel 6322 is connected to one side of the first linkage wheel 6321 through a shaft. A third linkage wheel 6323 is meshed on one side of the second linkage wheel 6322. A fourth linkage wheel 6324 is arranged on one side of the third linkage wheel 6323 through a shaft. A moving bar 6325 is meshed at the lower end of the fourth linkage wheel 6324. The moving bar 6325 is fitted inside the fitting block 61. An electric block 6326 is arranged at one end of the moving bar 6325. A contact switch 6327 is also arranged inside the fitting block 61, and the contact switch 6327 and the electric block 6326 are at the same horizontal position. A through hole 611 is opened on one side of the fitting block 61. The fitting airbag 62 includes an airbag main body 622 and an air outlet arc block 621 arranged at the upper end of the airbag main body 622. The air outlet arc block 621 covers one side of the through hole 611. An air outlet hole 623 is opened on one side of the air outlet arc block 621, and a plurality of groups of air outlet holes 623 are arranged. A heating element 6111 is arranged on one side of the inner wall of the through hole 611. A blower fan 612 is also arranged inside the through hole 611. A communicating air outlet 6211 is opened on one side of the air outlet arc block 621, and the communicating air outlet 6211 is communicated with the through hole 611, and the diameters of the two are the same. An arc-shaped air supply cavity 6212 is also opened inside the air outlet arc block 621, and the arc-shaped air supply cavity 6212 is communicated with the communicating air outlet 6211 and the air outlet holes 623.

[0043] Specifically, when the trainee is undergoing Korean training, the fitting arc-shaped block 63 descends, which will drive the rotation of the first linkage wheel 6321, the second linkage wheel 6322, the third linkage wheel 6323, and the fourth linkage wheel 6324, that is, drive the moving bar 6325 and the electric block 6326 to move until the electric block 6326 contacts the contact switch 6327. At this time, the temperature sensing module 81 starts to work, sensing the head temperature of the trainee wearing this device. When the head temperature is too low, the electric heating module 811 starts to work, causing the heating element 6111 to start heating. Then the power drive module 812 starts to work, driving the blower fan 612 to rotate, so that the hot air driven passes through the through hole 611, the communicating air outlet 6211, and the arc-shaped air supply cavity 6212, and finally blows out from the multiple air outlet holes 623, avoiding direct blowing of the hot air to scald the head. When the head temperature is too high, only the power drive module 812 starts to work, driving the blower fan 612 to rotate to blow out cool air. When the electric block 6326 and the contact switch 6327 are no longer in contact, the temperature sensing module 81, the electric heating module 811, and the power drive module 812 stop working.

[0044] In order to solve the technical problem that the traditional VR scenario dialogue practice device is not convenient for conveniently shooting and watching the voice and lip movements during training, resulting in the trainee being inconvenient to quickly find the wrong places for correction, as Figures 8 - 11 shown, the following preferred technical solutions are provided:

[0045] On one side of the combined electronic mechanism 3, there is a display screen 31 and a camera assembly 32. One end of the combined electronic mechanism 3 is provided with a long slot 33. Inside the long slot 33, a rotating shaft 34 is movably arranged. On the outer side of the rotating shaft 34, there is a first folding plate 35. One end of the first folding plate 35 is movably provided with a second hinge 352. On one side of the first folding plate 35, there is a first magnetic layer 351. Through the second hinge 352 on one side, a second folding plate 36 is movably arranged on the first folding plate 35. And the long slot 33, the rotating shaft 34, the first folding plate 35, and the second folding plate 36 are all provided in two groups. On both sides of the combined electronic mechanism 3, there are limit slots 39. Inside the limit slots 39, there is a magnetic connection with a screw 37. One end of the screw 37 is threadedly connected with a tightening assembly 38. Inside the screw 37, there is a threaded through groove 371. One end of the screw 37 is provided with a second magnetic layer 372. Inside the limit slot 39, there is an in-slot magnetic sheet 391. Inside the limit slot 39, there is a threaded groove 392. The second magnetic layer 372 is magnetically connected with the in-slot magnetic sheet 391. And one end of the screw 37 passes through the fixing block 2 and is fitted inside the limit slot 39.

[0046] The tightening assembly 38 includes a screwing head 381. A mating groove 382 is formed on one side of the screwing head 381. A threaded post 383 is disposed at the central position inside the mating groove 382. The threaded post 383 passes through the threaded through groove 371 and is threadedly connected inside the threaded groove 392. The mating groove 382 matches with one end of the screw 37. A fitting inner groove 361 is formed inside the second folding plate 36. Sliding grooves 362 are formed on both sides of the inner wall of the fitting inner groove 361. A fitting rotation groove 363 is formed at one end of the second folding plate 36, and the fitting rotation groove 363 communicates with the fitting inner groove 361. A support plate 364 is fitted inside the second folding plate 36. A sliding rotating shaft 3641 is disposed at one end of the support plate 364. The sliding rotating shaft 3641 is located inside the fitting inner groove 361. A sliding inner post 3642 is disposed inside the sliding rotating shaft 3641. The sliding inner post 3642 is slidably disposed inside the sliding groove 362. The first folding plate 35 and the second folding plate 36 are fitted inside the lower end of the VR main body 1, and the first folding plate 35 is magnetically connected to the inside of the VR main body 1 through the first magnetic layer 351.

[0047] Specifically, when the trainee conducts a scenario dialogue, the first folding plate 35 and the second folding plate 36 fitted inside the VR main body 1 are separated. Since the screw 37 passes through the fixing block 2 and is fitted inside the limiting groove 39, the combined electronic mechanism 3 is initially fixed to the lower end of the VR main body 1 by two sets of screws 37. At this time, the combined electronic mechanism 3 can rotate, so that the camera assembly 32 is aligned with the mouth of the trainee, and the mouth shape and pronunciation during his Korean training are photographed and recorded. When the combined electronic mechanism 3 rotates to the required angle, the tightening assembly 38 is screwed so that the threaded post 383 passes through the threaded through groove 371 and is threadedly connected inside the threaded groove 392. At this time, one end of the screw 37 is fitted inside the mating groove 382 until the tightening assembly 38 contacts and abuts against one side of the fixing block 2 to fix the angular position of the combined electronic mechanism 3. When the combined electronic mechanism 3 finishes shooting, it is necessary to view the stored video. By loosening the tightening assembly 38, separating the screw 37 and the limiting groove 39, that is, removing the combined electronic mechanism 3. By folding the second folding plate 36 and the first folding plate 35 on one side of the combined electronic mechanism 3 and pulling out the support plate 364 until the sliding rotating shaft 3641 is located inside the fitting rotation groove 363 and rotating the support plate 364 to make it abut against one side of the combined electronic mechanism 3, the combined electronic mechanism 3 is placed obliquely, which is convenient for the trainee to view the video.

[0048] To further better explain and illustrate the above embodiments, the present invention also provides an implementation scheme, an implementation method of a Korean learning training device for VR scenario dialogue practice, including the following steps:

[0049] Step 1: Wear this device on the head of the trainee through the connected elastic belt 5. Pull the fitting arc block 63 downward, and the flip airbag 64 will be inflated and expanded, so that the flip airbag 64 changes from a horizontal state to a vertical state, protecting the neck position of the trainee. The trainee conducts a scenario dialogue through the VR function module 8 and the VR main body 1;

[0050] Step 2: When the trainee conducts Korean training, the fitting arc block 63 descends. At this time, the temperature sensing module 81 works to sense the head temperature of the trainee wearing this device. When the head temperature is too low, the driven hot air blows out from multiple air outlet holes 623 to avoid directly scalding the head by the hot air. When the head temperature is too high, the driven blower fan 612 rotates to blow out cool air;
