In the prior art, most of the devices have low fidelity. Devices with high fidelity are difficult to disassemble, inconvenient for maintenance and repair, prone to problems, resulting in a reduced experience.

[0003] The patent with the publication number CN218567996U discloses a virtual reality VR interaction device. The patent includes an interaction device, and the interaction device includes a base. The shape of the base is arc-shaped. Both the left and right sides of the top of the base are fixedly connected with columns. The tops of the columns are respectively fixedly connected with a knee bearing plate and a hip bearing plate. The knee bearing plate and the hip bearing plate are arranged opposite to each other and both incline inward. The horizontal height of the hip bearing plate is higher than that of the knee bearing plate. A drive system is arranged inside the interaction device, which can realize the control of the virtual reality scene through the forward and backward tilting actions of the human body, and realize the coordination of the perception of the visual scene change and the body center of gravity change in virtual reality, and coordinate the whole body perception and the moving change of the virtual visual scene. Therefore, it can reduce the physiological stress response of the user. Moreover, the structure of this device is simple, suitable for use in an environment with limited space, with low equipment cost, used in a sitting position, saving physical strength. Although this patent solves the above problems, it still has problems such as low fidelity, single experience, low use comfort, unstable center of gravity and easy to fall, and low safety. Therefore, an interaction device for a virtual reality scene is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an interaction device for a virtual reality scene aiming at the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: an interactive device for a virtual reality scene, comprising a VR interactive cabin, the inner wall of the VR interactive cabin is fixedly connected with a cushion, the upper surface of the cushion is fixedly connected with an armrest, a dynamic base support bottom rod is arranged below the VR interactive cabin, the top of the dynamic base is fixedly connected with a connecting seat, the lower surface of the VR interactive cabin is fixedly connected with a vertical rod, the bottom end of the vertical rod is fixedly connected with a support bottom rod, both sides of the support bottom rod are fixedly connected with a connecting shaft, the circumferential surface of the connecting shaft is hinged with a movable connecting piece, and the bottom end of the movable connecting piece is fixedly connected with a connecting shaft.

A supporting anti-fall device is arranged below the VR interactive cabin to prevent the device from tipping over and causing injuries to the user. A foot pedal adjustment device is arranged below the VR interactive cabin to improve the user's comfort. The lower surface of the supporting bottom rod and the upper surface of the connecting seat are in contact with each other, and the triangular positioning plate and the inner surface of the card plate are in contact with each other. The front and rear sides of the card plate and the connecting seat are in contact with each other, and the two sides of the movable connecting piece and the supporting bottom rod are in contact with each other. The VR display device is connected to the VR interaction cabin through a data cable. At this time, the user wears the VR display device on his head and then sits on the cushion. The VR interaction cabin is installed to the connecting seat and the dynamic base through the vertical rod and the supporting bottom rod. Turning on the dynamic base can provide a somatosensory simulation experience during virtual interaction, giving the user a better sense of immersion. Turning off the dynamic base can make the user's VR experience smoother and avoid user discomfort. Turn the nut to remove the nut from the locking rod, and then pull the locking rod away from the triangular positioning plate. When the card plate is unlocked, the vertical rod and the supporting bottom rod can be lifted up, and the VR interaction cabin can be quickly removed from the dynamic base and the connecting seat. The VR interaction cabin is moved downward through the vertical rod and the supporting bottom rod and placed on the connecting seat. The supporting bottom rod drives the movable connecting piece to move downward through the connecting shaft, and the movable connecting piece drives the card plate to move downward. After the card plate contacts the inclined surface of the triangular positioning plate, it tilts up and continues to move downward until the triangular positioning plate is inserted into the card plate. At this time, the triangular positioning plate locks the VR interaction cabin to the connecting seat through the card plate.

When the device is closed and stored, the elastic reset action of the spring piece pulls the support block to reset through the connecting plate, so that the support block is vertical to the ground, and at the same time lifts the T-shaped clamping plate upward, and then releases the T-shaped clamping plate, the T-shaped clamping plate slides and falls in the F-shaped limit piece, and clamps the support block between the T-shaped clamping plate and the dynamic base and cannot rotate. When the support bottom rod moves downward, it drives the connecting plate to move downward, and the connecting plate drives the transmission long rod to move downward. After the bottom inclined surface of the transmission long rod contacts the top inclined surface of the support block, the support block is pushed to rotate through the guide between the inclined surfaces until the support block contacts the ground. After the transmission long rod resists the support block, after the support block contacts the ground, the transmission long rod drives the resistance oblique rod to insert into the resistance groove.

[0007] Preferably, the foot pedal adjusting device includes a telescopic slide rod, a connecting block, a rotating shaft, and a rotating pedal. The telescopic slide rod is slidably connected to the inner surface of the dynamic base. The connecting block is fixedly connected to one end of the telescopic slide rod away from the dynamic base. The rotating shaft is hinged to the inner surface of the connecting block. The rotating pedal is fixedly connected to one end of the rotating shaft. The foot pedal adjusting device further includes a limiting slide rail, a telescopic pedal, a movable groove, an inclined groove slide plate, an elastic telescopic rod, a resisting rod, and a vertical groove. The limiting slide rail is fixedly connected to the upper surface of the rotating pedal. The telescopic pedal is slidably connected to the inner surface of the limiting slide rail. The movable groove is opened on both sides inside the dynamic base. The inclined groove slide plate is slidably connected to the inner surface of the movable groove. The elastic telescopic rod is fixedly connected to the rear side of the inclined groove slide plate. The resisting rod is slidably connected to the inner surface of the inclined groove slide plate. The vertical groove is opened on both sides of the dynamic base. The lower surface of the telescopic pedal and the upper surface of the rotating pedal are in contact with each other. The rear end of the elastic telescopic rod is fixedly connected to the rear side of the movable groove. The resisting rod is slidably connected to the inner surface of the vertical groove. The rear end of the telescopic slide rod is fixedly connected to the front side of the inclined groove slide plate. The lower surface of the connecting cross bar is in contact with the circumferential surface of the resisting rod. Pull the connecting block forward, the connecting block drives the telescopic slide rod to slide forward in the dynamic base, so that the rotating shaft and the rotating pedal are away from the dynamic base. Rotate the rotating pedal through the rotating shaft to change the angle. Slide the telescopic pedal out in the limiting slide rail to change the length of the foot pedal. The transmission long rod descends to drive the connecting cross bar to descend. The connecting cross bar pushes the resisting rod to slide downward in the vertical groove. When the resisting rod slides downward, it pushes the inclined groove slide plate to slide forward in the movable groove through the guiding of the inner inclined surface of the inclined groove slide plate. When the inclined groove slide plate slides forward, it pushes the telescopic slide rod to slide out of the dynamic base. When the connecting cross bar moves upward, the resisting rod loses the resistance of the connecting cross bar. At this time, the elastic reset function of the elastic telescopic rod pulls the inclined groove slide plate to slide backward and reset. When the inclined groove slide plate resets, it pulls the telescopic slide rod to slide and contract into the dynamic base, and then pulls the connecting block to move backward. The connecting block then drives the rotating shaft and the rotating pedal to move backward and fit with the dynamic base.

[0008] Adopting the above technical solutions, the present invention can bring the following beneficial effects:

[0009] 1. For the interactive device in the virtual reality scenario, disassembling the VR interactive cabin from the dynamic base and the connecting seat facilitates the maintenance and inspection of the VR interactive cabin and the dynamic base, ensures the normal use of the device, improves the use safety of the device. After the triangular positioning plate is inserted into the clamping plate, the VR interactive cabin is locked on the connecting seat through the clamping plate, so that the VR interactive cabin can be quickly installed, improving the installation efficiency and use convenience.

[0010] 2. The interactive device of the virtual reality scene increases the support area of ​​the dynamic base after the support block contacts the ground, making the dynamic base more stable, preventing the dynamic base from falling and being damaged after being hit, or the user from having a stress reaction when using the device, causing the VR interactive cabin and the dynamic base to shake and fall, thereby improving the safety of the device. After the support block contacts the ground, the transmission long rod holds the support block, so that the support block can be quickly expanded to increase the support area without the user's manual adjustment again, thereby improving the convenience of use. The oblique resistance rod is inserted into the resistance groove to increase the supporting force of the support block, making the dynamic base more stable.

[0011] 3. The interactive device of the virtual reality scene has a rotating pedal away from the dynamic base, which is convenient for users to put their feet or legs on the rotating pedal, so that users can change their sitting posture according to their comfort, thereby improving the comfort of the device. The rotating pedal changes its angle by rotating the rotating axis, which can better fit the user's body sense and further improve the comfort of the device. The telescopic pedal is slid and pulled out in the limit slide rail to change the length of the foot pedal, thereby increasing the placement range of the user's feet or legs and improving the applicability of the device. When the inclined slot skateboard slides forward, it pushes the telescopic slide bar to slide out of the dynamic base, thereby quickly moving the rotating pedal to a suitable position and improving the ease of use of the device. The rotating pedal moves backward to fit the dynamic base, thereby preventing the telescopic slide bar and the rotating pedal from being damaged or broken by impact, thereby improving the safety of the device and reducing the floor space for easy placement.

[0022] Working principle: Connect the VR display device to the VR interaction cabin 1 through a data cable. At this time, the user wears the VR display device on his head and then sits on the cushion 2 to avoid dizziness caused by the incoordination between body operation and visual perception when the user uses the VR display device alone, which can effectively improve the user's VR experience. The VR interaction cabin 1 is installed on the connecting seat 5 and the dynamic base 4 through the vertical rod 51 and the supporting bottom rod 52. Turning on the dynamic base 4 can provide a somatosensory simulation experience during virtual interaction, giving the user a better sense of immersion.

After the card plate 55 contacts the inclined surface of the triangular positioning plate 56, it tilts up and continues to move downward until the triangular positioning plate 56 is inserted into the card plate 55. At this time, the triangular positioning plate 56 locks the VR interaction cabin 1 on the connecting seat 5 through the card plate 55, so that the VR interaction cabin 1 can be quickly installed, thereby improving the installation efficiency and the convenience of use.

[0023] See also Figures 1-7, on the basis of the above embodiments, in another embodiment of the present invention, the support and anti-fall device 6 includes a connecting rod 61, a support block 62, a connecting plate 63, a spring piece 64, an F-shaped limiting member 65, and a T-shaped clamping plate 66. The connecting rod 61 is fixedly connected to both sides of the dynamic base 4. Two support blocks 62 are respectively hinged to the front and rear ends of the circumferential surface of the connecting rod 61. The connecting plate 63 is fixedly connected between the two support blocks 62. Two spring pieces 64 are respectively fixedly connected to both sides of the dynamic base 4. The F-shaped limiting member 65 is fixedly connected to both sides of the dynamic base 4. The T-shaped clamping plate 66 is clamped on the inner surface of the F-shaped limiting member 65. After the support block 62 contacts the ground, the supporting area of the dynamic base 4 is increased, making the dynamic base 4 more stable, avoiding the dynamic base 4 from falling and being damaged after being impacted or the VR interaction cabin 1 and the dynamic base 4 from shaking and falling when the user uses the device, improving the safety of the device. The support and anti-fall device 6 further includes a connecting plate 67, a transmission long rod 68, a connecting cross bar 69, a contact groove 610, and a contact inclined rod 611. The connecting plate 67 is fixedly connected to one side of the support bottom rod 52 close to the support block 62. Two transmission long rods 68 are hinged to the inner surface of the connecting plate 67. The connecting cross bar 69 is fixedly connected between the two transmission long rods 68. The contact groove 610 is opened on the upper surface of the support block 62. The contact inclined rod 611 is fixedly connected to the side of the transmission long rod 68 away from the dynamic base 4. The bottom surface of the spring piece 64 and the upper surface of the connecting plate 63 are fixedly connected. The bottom end of the contact inclined rod 611 and the inner surface of the contact groove 610 are in contact with each other. The two sides of the transmission long rod 68 are in contact with the connecting seat 5. The two sides of the transmission long rod 68 are in contact with the dynamic base 4. The two sides of the connecting cross bar 69 are in contact with the dynamic base 4.

At the same time, the T-shaped clamping plate 66 is lifted upward, and then the T-shaped clamping plate 66 is released. The T-shaped clamping plate 66 slides and drops in the F-shaped limiting piece 65 and clamps the support block 62 between the T-shaped clamping plate 66 and the dynamic base 4 so that it cannot rotate, reducing the floor area of the device and facilitating storage, placement and transportation. When the support bottom rod 52 moves downward, it drives the connecting plate 67 to move downward. The connecting plate 67 drives the transmission long rod 68 to move downward. After the bottom inclined surface of the transmission long rod 68 contacts the top inclined surface of the support block 62, the support block 62 is pushed to rotate through the guidance between the inclined surfaces until the transmission long rod 68 abuts against the support block 62 after the support block 62 contacts the ground, enabling the support block 62 to quickly expand and increase the support area without the user manually adjusting again, improving the convenience of use. After the support block 62 contacts the ground, the transmission long rod 68 drives the abutting inclined rod 611 to insert into the abutting groove 610 to increase the supporting force of the support block 62 and make the dynamic base 4 more stable.

[0025] Please refer to Figures 1-7, on the basis of the above embodiments, in another embodiment of the present invention, the foot pedal adjusting device 7 includes a telescopic slide rod 71, a connecting block 72, a rotating shaft 73, and a rotating pedal 74. The telescopic slide rod 71 is slidably connected to the inner surface of the dynamic base 4. The connecting block 72 is fixedly connected to one end of the telescopic slide rod 71 away from the dynamic base 4. The rotating shaft 73 is hinged to the inner surface of the connecting block 72. The rotating pedal 74 is fixedly connected to one end of the rotating shaft 73. The rotating pedal 74 is away from the dynamic base 4, which is convenient for the user to place the foot or leg on the rotating pedal 74, enabling the user to change the sitting posture according to comfort, improving the comfort of the device. The rotating pedal 74 rotates through the rotating shaft 73 to change the angle, which can better fit the user's body feeling and further improve the comfort of the device. The telescopic pedal 76 is slid out within the limit slide rail 75 to change the length of the foot pedal, increasing the placement range of the user's foot or leg and improving the applicability of the device. The foot pedal adjusting device 7 further includes a limit slide rail 75, a telescopic pedal 76, a movable groove 77, an inclined groove slide plate 78, an elastic telescopic rod 79, a resisting rod 710, and a vertical groove 711. The limit slide rail 75 is fixedly connected to the upper surface of the rotating pedal 74. The telescopic pedal 76 is slidably connected to the inner surface of the limit slide rail 75. The movable groove 77 is opened on both sides inside the dynamic base 4. The inclined groove slide plate 78 is slidably connected to the inner surface of the movable groove 77. The elastic telescopic rod 79 is fixedly connected to the rear side of the inclined groove slide plate 78. The resisting rod 710 is slidably connected to the inner surface of the inclined groove slide plate 78. The vertical groove 711 is opened on both sides of the dynamic base 4. The lower surface of the telescopic pedal 76 and the upper surface of the rotating pedal 74 are in contact with each other. The rear end of the elastic telescopic rod 79 is fixedly connected to the rear side of the movable groove 77. The resisting rod 710 is slidably connected to the inner surface of the vertical groove 711. The rear end of the telescopic slide rod 71 is fixedly connected to the front side of the inclined groove slide plate 78. The lower surface of the connecting cross bar 69 is in contact with the circumferential surface of the resisting rod 710. When the inclined groove slide plate 78 slides forward, it pushes the telescopic slide rod 71 to slide out of the dynamic base 4, thereby quickly moving the rotating pedal 74 to a suitable position and improving the convenience of using the device. When the rotating pedal 74 moves backward and fits with the dynamic base 4, it prevents the telescopic slide rod 71 and the rotating pedal 74 from being damaged by impact and breaking, improving the safety of the device. At the same time, it reduces the floor area and is convenient for placement.

[0026] Working principle: Pull the connecting block 72 forward. The connecting block 72 drives the telescopic slide rod 71 to slide forward in the dynamic base 4, making the rotating shaft 73 and the rotating pedal 74 move away from the dynamic base 4, which is convenient for the user to place the foot or leg on the rotating pedal 74, enabling the user to change the sitting posture according to comfort, improving the comfort of the device. Rotating the rotating pedal 74 through the rotating shaft 73 to change the angle can better fit the user's body feeling and further improve the comfort of the device. Sliding the telescopic pedal 76 out in the limit slide rail 75 to change the length of the footrest, increasing the placement range of the user's foot or leg and improving the applicability of the device. The transmission long rod 68 descends to drive the connecting cross bar 69 to descend. The connecting cross bar 69 pushes the abutting rod 710 to slide downward in the vertical groove 711. When the abutting rod 710 slides downward, it pushes the inclined groove slide plate 78 to slide forward in the movable groove 77 through the guiding of the inner inclined surface of the inclined groove slide plate 78. When the inclined groove slide plate 78 slides forward, it pushes the telescopic slide rod 71 to slide out of the dynamic base 4, thereby quickly moving the rotating pedal 74 to a suitable position and improving the convenience of use of the device. When the connecting cross bar 69 moves upward, the abutting rod 710 loses the abutment of the connecting cross bar 69. At this time, the elastic reset function of the elastic telescopic rod 79 pulls the inclined groove slide plate 78 to slide backward and reset. When the inclined groove slide plate 78 resets, it pulls the telescopic slide rod 71 to slide and contract into the dynamic base 4, and then pulls the connecting block 72 to move backward. The connecting block 72 then drives the rotating shaft 73 and the rotating pedal 74 to move backward and fit with the dynamic base 4, avoiding the telescopic slide rod 71 and the rotating pedal 74 from being damaged and broken by impact, improving the safety of the device, and at the same time reducing the floor area and being convenient for placement.
