Description

Technical Field

[0001] The present invention relates to the technical field of emergency desensitization training equipment, and in particular to a high-altitude stress desensitization training cabin simulated with the assistance of VR. Background Art

[0002] VR psychological desensitization simulations primarily utilize biofeedback and virtual reality technologies to train users to overcome fear. Scenario-based simulation training primarily leverages VR technology to immerse users in the situation, creating a sense of immersion and guiding them through psychological desensitization. This method primarily involves slowly exposing patients to situations that trigger neurotic anxiety and fear, and then using a state of psychological relaxation to combat these feelings, ultimately eliminating the anxiety or fear. VR psychological desensitization simulations primarily include desensitization for social phobia, acrophobia, claustrophobia, and anxiety disorders. Desensitization for acrophobia primarily uses VR technology to simulate high-altitude environments, training users to safely overcome height sensitivity. High-altitude emergency desensitization training primarily utilizes VR technology in conjunction with a training chamber. Within the enclosed chamber, appropriate training facilities are installed, and VR technology is used to simulate the surrounding environment, allowing users to safely overcome height sensitivity.

[0003] However, the existing VR simulated high-altitude emergency desensitization training cabin has poor stability and adaptability to the simulated walking platform inside the training cabin, and needs to be equipped with a waist support component to ensure that the user can walk in place on the platform. The equipment cost is high, and the waist support component will restrain the user's waist, which will reduce the simulation authenticity of the user's high-altitude fall simulation; or a motor-driven walking platform is used, but the motor drive is not convenient for real-time adaptation to the user's walking speed and angle.

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

[0016] 1. The present invention simulates a high-altitude virtual environment through a VR simulation device by arranging a walking platform, a support plate, a flexible sleeve, a tray, a guide groove, a first ball, a second ball, a first anti-slip layer, and a second anti-slip layer. The user stands on the top center of the walking platform. During the VR high-altitude simulation, the user can perform high-altitude VR simulation projects such as walking on a single-plank bridge, walking on the edge of a high-rise building, and walking on a high-altitude glass plank road. The first anti-slip layer performs a first anti-slip treatment on the outside of the flexible sleeve, and the second anti-slip layer performs a second anti-slip treatment on the inner wall of the flexible sleeve to ensure the friction between the flexible sleeve and the support plate, and to ensure the stability of the flexible sleeve when the user walks on the outside of the support plate. The disc-shaped structure of the support plate provides a planar support for the user on the top of the walking platform, thereby improving the authenticity of the simulated flat single-plank bridge surface on the top of the walking platform. The spherical bottom structure of the support plate is The spherical bottom support at the bottom of the support plate can effectively ensure that the support plate can be tilted at different angles. When the user's body center of gravity deviates from the center range of the top of the support plate, the spherical bottom structure at the bottom of the support plate can normally tilt and offset along the guide groove at the top of the tray, and the operation is convenient and quick; at the same time, the spherical bottom structure at the bottom of the support plate can effectively ensure the smoothness and stability of the movement of the flexible sleeve on the support plate, and can effectively ensure that the flexible sleeve can slide at different angles outside the support plate; under the full coverage simulated rolling guidance processing of the first ball and the second ball, the movement angle of the flexible sleeve changes with the change of the user's walking force angle, and the movement speed of the flexible sleeve changes with the change of the user's walking speed, so that the walking platform can normally perform multi-angle movement and multi-speed adaptive adjustment, thereby improving the authenticity and adaptability of VR simulation training;When the user walks on the surface of the first anti-slip layer, the user's body is pressed on the first anti-slip layer under the action of gravity. When the user walks and steps, the user's sole and the first anti-slip layer interact with each other, and the first anti-slip layer is displaced. The movement direction of the first anti-slip layer is opposite to the direction of the user's walking force. The first ball performs rolling contact and guidance on the surface of the first anti-slip layer on the inner side of the guide groove, and the second ball performs rolling contact and guidance on the surface of the second anti-slip layer on the outside of the support plate, which can effectively ensure the smoothness of the movement of the first anti-slip layer and the second anti-slip layer, and then ensure the smoothness of the movement of the flexible sleeve on the outside of the support plate, so that the flexible sleeve can move along the support plate when the user walks on the walking platform surface, which can effectively ensure that the user can walk in place on the top of the walking platform to simulate normal walking in VR, and the flexible sleeve of the walking platform does not move when the user steps in place. Only when the user is in a normal walking state in the VR simulation can it truly act on the walking platform to simulate normal walking. This further improves the realism of VR simulation. Under the fully covered simulated rolling guidance of the first and second balls, the flexible sleeve's movement angle changes with the user's walking force angle, and the flexible sleeve's movement speed changes with the user's walking speed, allowing the walking platform to normally perform multi-angle movement and multi-speed adaptive adjustment, thereby improving the realism and adaptability of VR simulation training. As the first protrusion is continuously inserted and extended from the inside of the third groove, the second protrusion is also continuously inserted and extended from the inside of the fourth groove, further strengthening the contact stability between the first ball and the first anti-slip layer, as well as the contact stability between the second ball and the second anti-slip layer, thereby effectively improving the safety and stability of the flexible sleeve's movement. When the second protrusion is inserted into the inside of the fourth groove, the second protrusions are radially distributed in three directions outside the first protrusion, further strengthening the contact stability between the first ball and the first anti-slip layer, as well as the contact stability between the second ball and the second anti-slip layer.

[0017] 2. The present invention provides a first annular slide rail, a second annular slide rail, a third annular slide rail, a fourth annular slide rail, a first slide groove, a second slide groove, and a third slide groove. When the user stands at the center of the top of the walking platform, the support head is located inside the first annular slide rail of the guide plate, and within this range, the support head can perform an annular motion along the first annular slide rail, which can effectively prevent the device connection line from obstructing the movement of the user; when the user deviates on the walking platform, the device connection line swings along with the user's deviation, and the device connection line drives the support head to move, and the support head enters the second annular slide rail from the inside of the first annular slide rail through the first slide groove, so that the adaptability between the device connection line and the user's body is improved, and the VR device is prevented from falling off due to the tightening of the device connection line or the complete tightening of the safety rope when the user's body tilts or deviates, which can prevent the VR device from falling off or the safety rope from being completely tightened, which can prevent the VR device from falling off or the safety rope from being completely tightened, which can also effectively ensure the stability between the device connection line and the user's body; At this time, the support head located in the fourth annular slide rail slides from the third slide groove to the inner side of the third annular slide rail, which can effectively prevent the user from colliding with the walking platform and the inner wall of the cabin when falling, and can effectively ensure the safety of the user's fall simulation in VR simulation.

The center of the inner wall of the first groove 15 and the second groove is provided with a third groove 17. A plurality of fourth grooves 18 are provided on the inner side, and a plurality of first protrusions 19 matching the third grooves 17 are provided on the outer walls of the first ball 11 and the second ball 12. A second protrusion 20 matching the fourth groove 18 is provided on the surface of the first protrusion 19. A first spherical groove 21 matching the first ball 11 is provided on the top of the inner wall of the tray 9, and a second spherical groove 22 matching the second ball 12 is provided on the outer wall of the support plate 6; the first groove 15 and the second groove are both equilateral triangular structures, the third groove 17 is a circular structure, and the fourth groove 18 is a long strip structure; three fourth grooves 18 are provided on the inner side of each of the third grooves 17, and the three fourth grooves 18 are distributed in a "Y" shape, and the ends of the three fourth grooves 18 are They are respectively tangent to the three inner angles of the equilateral triangle structure; the triangular directions of two adjacent first grooves 15 are symmetrically distributed, and the spacing between two adjacent first grooves 15 is equal; the triangular directions of two adjacent second grooves are symmetrically distributed, and the spacing between two adjacent second grooves is equal; the equipment connecting line 4 is connected to a safety rope and a VR simulation device, and a cabin door 30 is hinged on one side of the outer wall of the cabin body 1, and the inner wall of the cabin body 1 is provided with a rotatably connected support plate 31 below the cabin door 30, and the support plate 31 is rotatably connected to the cabin body 1 through a support shaft 32, and the outer wall of the cabin body 1 is provided with a servo motor, and the output shaft of the servo motor is connected to the support shaft 32 through a reducer, and the outer wall of the cabin door 30 is provided with a storage groove 33 matching the support plate 31.

[0032] The fourth groove 18 extends to the outside of the third groove 17, and the inner walls of the first groove 15 and the second groove are tangent to the fourth groove 18. The second protrusion 20 extends to the outside of the first protrusion 19. The length of the second protrusion 20 is less than the length of the fourth groove 18. When the first protrusion 19 is inserted into the inner side of the third groove 17, the second protrusion 20 is inserted into the inner side of the fourth groove 18, which can effectively extend the working range of the fourth groove 18. The fourth groove 18 can quickly connect and contact with the second protrusion 20 on the surface of different first balls 11 or second balls 12, thereby ensuring the stability of the movement of the first ball 11 and the first anti-slip layer 13 and the second ball 12 and the second anti-slip layer 14, thereby enhancing the stability of the movement of the flexible sleeve 7.

[0033] The outer diameter of the first ball 11 is larger than the inscribed circle diameter of the first groove 15, and the outer diameter of the first ball 11 is smaller than the side length of the first groove 15, ensuring that the first groove 15 can completely cover the outside of the first ball 11, thereby enhancing the stability and safety of the contact connection between the first ball 11 and the first anti-slip layer 13; the outer diameter of the second ball 12 is larger than the inscribed circle diameter of the second groove, and the outer diameter of the second ball 12 is smaller than the side length of the second groove, thereby ensuring that the second groove can completely cover the outside of the second ball 12, thereby enhancing the stability and safety of the contact connection between the second ball 12 and the second anti-slip layer 14.

[0034] The specific implementation method is as follows: when in use, by setting the walking platform 5, the support plate 6, the flexible sleeve 7, the tray 9, the guide groove 10, the first ball 11, the second ball 12, the first anti-slip layer 13, and the second anti-slip layer 14, the user opens the hatch 30, and the servo motor drives the support shaft 32 to rotate through the reducer, and the support shaft 32 drives the support plate 31 to swing, and adjusts the support plate 31 to a horizontal state. The user steps on the support plate 31 and walks to the top center of the walking platform 5, and then adjusts the servo motor to drive the support shaft 32 to rotate and reset through the reducer, and the support plate 31 is stored in the storage groove 33, which can effectively prevent the support plate 31 from being simulated by the user. When walking at high altitude, the user will collide with the user when falling, so as to prevent the support plate 31 from causing damage to the user; the support head 3 can be pulled by the device connection line 4 to slide inside the guide plate 2, so as to adjust the position of the device connection line 4 and the distance between the device connection line 4 and the user, and the user puts on the safety rope on the device connection line 4 and the VR simulation device; start the VR-assisted simulated high-altitude stress desensitization training, and use the VR simulation device to simulate the high-altitude virtual environment. The user stands at the top center of the walking platform 5. During the VR high-altitude simulation process, the user can perform high-altitude VR simulation projects such as walking on a single-plank bridge, walking on the edge of a high-rise building, and walking on a high-altitude glass plank road.

[0035] Take the single-plank bridge walking project as an example: the user stands at the top center of the walking platform 5 and walks forward along the walking platform 5. When the center of gravity of the user's two feet is at the top center of the walking platform 5, that is, the user walks horizontally on the top of the walking platform 5, the user walks along the single-plank bridge without deviation. At this time, the support plate 6 remains stable, and the first anti-slip layer 13 performs the first anti-slip treatment on the outside of the flexible sleeve 7 to ensure the friction between the user and the flexible sleeve 7 when walking, and ensures that when the user walks, the flexible sleeve 7 can move accordingly with the force of the user's feet, thereby ensuring that the user always moves in a small area at the top center of the walking platform 5 during normal walking. The second anti-slip layer 14 A second anti-slip treatment is performed on the inner wall of the flexible sleeve 7 to ensure the friction between the flexible sleeve 7 and the support plate 6, and to ensure the stability of the flexible sleeve 7 when the user walks on the outside of the support plate 6; the disc-shaped structure of the support plate 6 provides a plane support for the user at the top of the walking platform 5, thereby improving the authenticity of the simulated flat single-plank bridge surface at the top of the walking platform 5; the ball-bottom structure of the support plate 6 performs ball-bottom support at the bottom of the support plate 6, which can effectively ensure that the support plate 6 can be tilted at different angles. When the center of gravity of the user's body deviates from the center range of the top of the support plate 6, the ball-bottom structure at the bottom of the support plate 6 can be tilted and offset normally along the guide groove 10 at the top of the tray 9, and the operation is convenient and quick; at the same time, the ball-bottom structure at the bottom of the support plate 6 The structure can effectively ensure the smoothness and stability of the movement of the flexible sleeve 7 on the support plate 6, and can effectively ensure that the flexible sleeve 7 can slide at different angles outside the support plate 6; when the user is walking on the high-altitude single-plank bridge VR simulation, when the user's center of gravity deviates from the center of the top of the walking platform 5, the user deviates from the center of the single-plank bridge in the VR simulation and begins to tilt and deflect. In reality, the support plate 6 on the walking platform 5 tilts and deflects when the user's center of gravity deviates. The support plate 6 tilts and deflects along the guide groove 10 on the top of the tray 9. When the user adjusts his steps on the single-plank bridge in the VR simulation, in reality, the user's foot position on the top of the walking platform 5 changes, and the support plate 6 adjusts under the action of the user's center of gravity. The tilt angle of the support plate 6 is adjusted as the user adjusts on the VR simulated single-plank bridge. When the user readjusts and resets to the center of the upper surface of the single-plank bridge in the VR simulation, the user adjusts and resets to the center range of the top of the walking platform 5 in reality. When the user completely deviates from the upper surface of the single-plank bridge and falls, in reality, the user deviates greatly above the support plate 6 and the tilt angle of the support plate 6 is large, and the user cannot stand normally on the support plate 6. The user falls from the support plate 6 of the walking platform 5 and falls into the interior of the cabin 1. The sponge block 8 inside the cabin 1 elastically cushions the user to ensure the user's safety, which can effectively enhance the simulation authenticity and perceived authenticity of the VR high-altitude simulation.

[0036] When the user stands on the first anti-slip layer 13 of the flexible sleeve 7, the user walks on the surface of the first anti-slip layer 13, and the user's body is pressed on the first anti-slip layer 13 under the action of gravity. When the user walks and steps, the user's sole and the first anti-slip layer 13 interact with each other, and the first anti-slip layer 13 is displaced. The movement direction of the first anti-slip layer 13 is opposite to the direction of the user's walking force. The first ball 11 performs rolling contact guidance on the surface of the first anti-slip layer 13 on the inner side of the guide groove 10, and the second ball 12 performs rolling contact guidance on the surface of the second anti-slip layer 14 outside the support plate 6, which can effectively ensure the smoothness of the movement of the first anti-slip layer 13 and the second anti-slip layer 14, and thus ensure the smoothness of the movement of the flexible sleeve 7 on the outside of the support plate 6, so that the flexible sleeve 7 can be used when the user walks on the surface of the walking platform 5. When walking on the surface, it can move along the support plate 6, which can effectively ensure that the user can walk in place on the top of the walking platform 5 to simulate normal walking in VR, and the flexible sleeve 7 of the walking platform 5 does not move when the user steps in place. Only when the user is in a normal walking state in the VR simulation can it truly act on the walking platform 5, further improving the authenticity of the VR simulation. Under the full coverage simulated rolling guidance processing of the first ball 11 and the second ball 12, the movement angle of the flexible sleeve 7 changes with the change of the user's walking force angle, and the movement speed of the flexible sleeve 7 changes with the change of the user's walking speed, so that the walking platform 5 can normally perform multi-angle movement and multi-speed adaptive adjustment, thereby improving the authenticity and adaptability of VR simulation training;

[0037] When the first anti-slip layer 13 and the first ball 11 are in rolling contact, the first ball 11 is continuously inserted and extended from the inner side of the first groove 15, which can effectively strengthen the first anti-slip layer 13 in normal movement while ensuring the stability of the first anti-slip layer 13; when the second anti-slip layer 14 and the second ball 12 are in rolling contact, the second ball 12 is continuously inserted and extended from the inner side of the second groove, which can effectively strengthen the second anti-slip layer 14 in normal movement while ensuring the stability of the second anti-slip layer 14; the first protrusions 19 on the surfaces of the first ball 11 and the second ball 12 are continuously inserted and extended during movement. Inserting and extending from the inner side of the third groove 17 can further enhance the contact stability between the first ball 11 and the first anti-slip layer 13, as well as the contact stability between the second ball 12 and the second anti-slip layer 14. When the first protrusion 19 is continuously inserted and extended from the inner side of the third groove 17, the second protrusion 20 is also continuously inserted and extended from the inner side of the fourth groove 18, which can further enhance the contact stability between the first ball 11 and the first anti-slip layer 13, as well as the contact stability between the second ball 12 and the second anti-slip layer 14. This effectively improves the safety and stability of the movement of the flexible sleeve 7.

[0038] The first groove 15 and the second groove of the equilateral triangle structure are sleeved on the ball, which can effectively enhance the stability of the contact connection between the first groove 15 and the first ball 11, as well as the stability of the contact connection between the first groove 15 and the first ball 11; the three fourth grooves 18 distributed in a "Y" shape make it possible for the second protrusion 20 to be radially distributed along three directions on the outside of the first protrusion 19 when the second protrusion 20 is inserted into the inner side of the fourth groove 18, which can further enhance the contact connection stability between the first ball 11 and the first anti-slip layer 13, as well as the contact connection stability between the second ball 12 and the second anti-slip layer 14; the three fourth grooves 18 of the first groove 15 are arranged in a "Y" shape, so that when the second protrusion 20 is inserted into the inner side of the fourth groove 18, the second protrusion 20 is radially distributed along three directions on the outer side of the first protrusion 19, which can further enhance the contact connection stability between the first ball 11 and the first anti-slip layer 13, as well as the contact connection stability between the second ball 12 and the second anti-slip layer 14; The angles are symmetrically distributed, and the spacing between two adjacent first grooves 15 is equal, so that the first grooves 15 are more evenly distributed, and the first protrusion 19 is more convenient and stably in contact and connected with the third groove 17, which can further enhance the stability of the contact and connection between the first ball 11 and the first anti-slip layer 13 when the first anti-slip layer 13 moves; the triangles of two adjacent second grooves are symmetrically distributed, and the spacing between two adjacent second grooves is equal, so that the first protrusion 19 is more convenient and stably in contact and connected with the third groove 17, which can further enhance the stability of the contact and connection between the first ball 11 and the first anti-slip layer 13 when the first anti-slip layer 13 moves.

[0040] A support rod 34 is provided on the inner side of the support head 3, and a plurality of rotatably connected rollers 16 are provided on the outer wall of the support rod 34. The rollers 16 are parallel to the length direction of the support rod 34, and the support rod 34 supports the support head 3 as a whole. When the support head 3 moves, the rollers 16 roll on the outer wall of the support rod 34, and the rollers 16 roll in contact with the inner walls of the first annular slide 23, the second annular slide 24, the third annular slide 25, the fourth annular slide 26, the first slide groove 27, the second slide groove 28, and the third slide groove 29, which can effectively ensure the safety and stability of the movement of the support head 3.

[0041] The specific implementation method is as follows: when in use, by setting the first annular slide rail 23, the second annular slide rail 24, the third annular slide rail 25, the fourth annular slide rail 26, the first slide groove 27, the second slide groove 28, and the third slide groove 29, after the user wears the VR device and the safety rope, when the user has a large displacement, the device connection line 4 moves accordingly, and the support head 3 movably connects the device connection line 4 and the guide plate 2 together, and the support head 3 moves with the top of the device connection line 4; when the user stands at the top center of the walking platform 5, the support head 3 is located on the inner side of the first annular slide rail 23 of the guide plate 2, and within this range, the support head 3 can move in a circular motion along the first annular slide rail 23, which can effectively prevent the device connection line 4 from hindering the user's movement; when the user deviates on the walking platform 5, the device connection line 4 swings along with the user's deviation, and the device connection line 4 drives the support head 3 to move, and the support head 3 enters the second annular slide rail 24 from the inner side of the first annular slide rail 23 through the first slide groove 27, so that the adaptability between the device connection line 4 and the user's body is improved, which prevents the device connection line 4 from being tightened when the user's body tilts and deviates, causing the VR device to fall off, or the safety rope is completely tightened, thereby preventing the VR device from falling off. The VR simulation reality is reduced when the user falls or the safety rope is completely tightened, and the stability between the device connection line 4 and the user's body is effectively guaranteed; when the user deviates seriously and falls from the walking platform 5, the device connection line 4 deviates with the user at a large angle and a large length, and the support head 3 passes through the second slide groove 28 from the second annular slide rail 24 to the inner side of the third annular slide rail 25, and the support head 3 passes through the third slide groove 29 from the third annular slide rail 25 to the inner side of the fourth annular slide rail 26, which can further prevent the device connection line 4 from being tightened when the user's body tilts and deviates, causing the VR device to fall off or the safety rope to be completely tightened. The rope is fully tightened, which can further ensure the authenticity of the user's fall during VR simulation training. When the user deviates and falls, the user is adjusted to a vertical falling state under the traction of the safety rope. During the process of adjusting the safety rope from the inclined state to the vertical state, the device connection line 4 is tightened and swings fine-tuned with the safety rope. At this time, the support head 3 located in the fourth annular slide rail 26 slides from the third slide groove 29 to the inner side of the third annular slide rail 25, which can effectively prevent the user from colliding with the walking platform 5 and the inner wall of the cabin 1 when falling, and can effectively ensure the safety of the user's fall simulation in VR simulation.
