[0017] S1: The staff can place the VR helmet on the display stand and then set the initial suspension position of the VR helmet through a simple calibration procedure of the control module. Once the calibration is completed, the control module will activate the array of the first electromagnet and the second electromagnet to generate sufficient magnetic field force to overcome the gravity of the VR helmet, so that it slowly rises and stabilizes at the preset height;

[0018] S2: By continuously reading the position sensor data, the control module can adjust the output of the first electromagnet and the second electromagnet in real time to cope with any external interference or slight movement of the user's head, ensuring that the VR helmet always maintains a stable suspension state;

[0019] S3: Users can interact with the control module through gesture recognition sensors or touch screens, such as adjusting the suspension height, rotating the VR helmet direction, or activating specific VR functions;

[0020] S4: When the user completes the experience or encounters an emergency, the user can trigger the safe landing procedure by pressing the emergency button or using a voice command. The control module will gradually weaken the magnetic field strength, allowing the VR helmet to smoothly descend to the bottom surface of the display stand.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Through the cooperation of the permanent magnet with the first electromagnet and the second electromagnet, the VR helmet can be displayed in a magnetic field suspension manner, which can create a display effect full of technology. By controlling the magnetic fields of the first electromagnet and the second electromagnet, the VR helmet can be rotated, moved vertically and other actions on the display stand, allowing users to observe the appearance and details of the VR helmet from different angles and better understand its design and functions, thereby realizing a multi-angle and dynamic display of the VR helmet, thereby improving the flexibility of the VR helmet. Through the emergency button, when an emergency occurs, the user or staff can quickly press the emergency button to trigger the corresponding emergency procedure, immediately stop the demonstration, shut down related equipment, and effectively prevent the further expansion of the accident. At the same time, the backup power supply can continue to provide power support for the demonstration device for a certain period of time in the event of a sudden power outage or a failure of the main power supply, ensuring that the user can safely exit the demonstration warehouse, and also prevent data loss and equipment damage;

[0023] Second, the elasticity and cushioning performance of the rubber ring can play a cushioning role when the user wears the VR helmet, reduce the pressure of the VR helmet on the head, and improve the wearing comfort. When the user's head shakes slightly during the experience, the rubber ring can absorb part of the impact force to prevent the VR helmet from directly hitting the head and causing discomfort. At the same time, the surface of the rubber ring is usually rough, which can increase the friction between the inner wall of the VR helmet and the head, making the VR helmet more stable and not easy to slip. The user can be fixed to the seat by the fixing strap and buckle. During the VR demonstration, the user may unconsciously make some large movements because of being immersed in the virtual scene. The fixing strap and buckle can prevent them from slipping or falling from the seat during the experience, ensuring the safety of the user. At the same time, by fixing the user's body position and reducing unnecessary body shaking, the user can be more focused on the virtual scene and enhance the immersion of the VR experience;

[0024] 3. The height of the head placement block can be adjusted according to the user's height by adjusting the bolt, so that the user's head can be in a comfortable and natural position when using VR equipment, effectively improving the comfort of the viewing experience. The roller can reduce the friction between the head placement block and the inner wall of the bar-shaped slot, preventing wear on the placement block itself or surrounding parts during the adjustment process, making it easier and more flexible to adjust the position of the head placement block, thereby extending the service life of the placement block;

[0025] Fourth, the ventilation fan can speed up the circulation of air inside and outside the demonstration warehouse, ensure the freshness of the air inside the demonstration warehouse and the appropriate humidity and temperature, thus providing users with a comfortable experience environment. The dust cover and dust net can prevent dust and debris from entering the ventilation fan, effectively prevent dust from adhering to the fan blades and affecting the normal operation of the ventilation fan, thereby improving the ventilation efficiency and service life of the ventilation fan. At the same time, with the dust cover and dust net, the staff only needs to clean the dust on the surface of the dust net regularly during cleaning, which is much simpler and more convenient than cleaning the inside of the ventilation fan, reducing the maintenance cost and difficulty. The combination of the inclined block and the anti-slip strip can make it more convenient for users to enter and exit the demonstration warehouse, prevent tripping and other situations caused by the height difference between the demonstration warehouse and the ground, thereby improving the safety of the demonstration warehouse. At the same time, the presence of the anti-slip strip increases the friction of the inclined block surface, which can effectively prevent users from slipping due to loose contact between the soles and the inclined block surface when entering and exiting. Especially when the user may carry some items or walk in a hurry, the anti-slip strip can effectively ensure the walking safety of the audience. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In use, the VR helmet 3 can be displayed in a magnetic field suspension manner by the cooperation of the permanent magnet 4 with the first electromagnet 7 and the second electromagnet 9, which can create a display effect full of technology. By controlling the magnetic fields of the first electromagnet 7 and the second electromagnet 9, the VR helmet 3 can be rotated, moved vertically, and other actions on the display stand 1, so that the user can observe the appearance and details of the VR helmet 3 from different angles and better understand its design and function, thereby realizing a multi-angle and dynamic display of the VR helmet 3, thereby improving the flexibility of the VR helmet 3.

[0038] like Figure 1 , Figure 2 and Figure 4-Figure 6As shown, the protective structure includes a rubber ring 17 fixed to the inner wall of the VR helmet 3, a rubber pad 18 is fixed to the bottom surface of the VR glasses on the VR helmet 3, the fixing structure includes two driving modules 19 fixed to the inner bottom surface of the demonstration chamber 2, the top surface of the driving module 19 is fixed to the bottom surface of the seat 13, fixing belts 20 are fixed on both sides of the inner wall of the seat 13, one end of the two fixing belts 20 are respectively fixed with buckles 21, and the two buckles 21 are adapted to each other, and the adjustment structure includes a strip-shaped through groove 22 opened on the rear side of the seat 13, the inner wall of the strip-shaped through groove 22 is slidably connected with a slider 23, the side wall of the slider 23 is provided with a sliding structure, a placement block 24 is fixed to the slider 23, a silicone pad 25 is fixed to the inner wall of the placement block 24, an adjusting bolt 26 is threadedly connected to the slider 23, and the adjusting bolt 26 is threadedly connected to the threaded hole opened on the slider 23.

[0039] In use, the elasticity and buffering performance of the rubber ring 17 can play a buffering role when the user wears the VR helmet 3, reduce the pressure of the VR helmet 3 on the head, and improve the wearing comfort. When the user's head shakes slightly during the experience, the rubber ring 17 can absorb part of the impact force to prevent the VR helmet 3 from directly hitting the head and causing discomfort. At the same time, the surface of the rubber ring 17 is usually rough, which can increase the friction between the inner wall of the VR helmet 3 and the head, making the VR helmet 3 more stable to wear and not easy to slip. The user can be fixed on the seat 13 by the fixing belt 20 and the buckle 21. During the VR demonstration, the user may unconsciously make some large movements because of being immersed in the virtual scene. The fixing belt 20 and the buckle 21 can prevent the user from slipping or falling from the seat 13 during the experience, ensuring the safety of the user. At the same time, by fixing the user's body position and reducing unnecessary body shaking, the user can be more focused on the virtual scene and enhance the immersion of the VR experience. The height of the head placement block 24 can be adjusted according to the height of the user by adjusting the bolt 26, so that the user's head can be in a comfortable and natural position when using the VR device, effectively improving the comfort of the viewing experience.

At the same time, with the dust cover 31 and the dust net 32, the staff only needs to regularly clean the dust on the surface of the dust net 32 ​​during cleaning, which is much simpler and more convenient than cleaning the interior of the ventilation fan 30, reducing the maintenance cost and difficulty. The cooperation of the inclined block 33 and the anti-slip strip 34 can make it more convenient for users to enter and exit the demonstration warehouse 2, and prevent tripping and other situations caused by the height difference between the demonstration warehouse 2 and the ground, thereby improving the safety of the demonstration warehouse 2. At the same time, the presence of the anti-slip strip 34 increases the friction force on the surface of the inclined block 33, which can effectively prevent users from slipping due to loose contact between the sole and the surface of the inclined block 33 when entering and exiting. Especially when the user may carry some items or walk in a hurry, the anti-slip strip 34 can effectively ensure the walking safety of the audience.

[0044] The present invention also provides a VR demonstration exhibition device and an exhibition method thereof, and the specific steps are as follows:

[0045] S1: The staff can place the VR helmet 3 on the display stand 1, and then set the initial suspension position of the VR helmet 3 through a simple calibration procedure of the control module 10.

[0046] S2: By continuously reading the data of the position sensor 12, the control module 10 can adjust the output of the first electromagnet 7 and the second electromagnet 9 in real time to cope with any external interference or slight movement of the user's head, ensuring that the VR helmet 3 always maintains a stable suspension state;

[0047] S3: The user may interact with the control module 10 through a gesture recognition sensor or a touch screen, for example, to adjust the suspension height, rotate the VR helmet 3 direction, or activate a specific VR function;

[0048] S4: When the user completes the experience or encounters an emergency, the user can trigger the safe landing procedure by pressing the emergency button 14 or through a voice command. The control module 10 will gradually weaken the magnetic field strength, allowing the VR helmet 3 to smoothly descend to the bottom surface of the display stand 1.
