[0025] The first fixing rod 214 is slidably connected to the inner wall of the first sliding groove 215, and the second fixing rod 29 is slidably connected to the inner wall of the second sliding groove 210. The movement of the second sliding groove 210 acts on the first fixing rod 214 on the front side of the slider 23, so that the first fixing rod 214 moves to the left.

[0026] A seat 26 is fixedly connected to the top of the box body 21 , a connecting rod 211 is fixedly connected to the top of the seat 26 , and a headrest 212 is fixedly connected to the top of the connecting rod 211 .

[0027] When the above-mentioned device is used in practice, a passenger sits on the top of the seat 26 and the middle of the clamping block 25, and the hydraulic cylinder 27 is started. The hydraulic cylinder 27 drives the connecting plate 28 to move to the bottom. The connecting plate 28 moves to the bottom, and the second fixed rod 29 on the top of the connecting plate 28 drives the second slide groove 210 on the front of the moving rod 216 to move to the right.

When the mobile device 3 performs scene simulation, the passenger can be fixed to prevent the passenger from falling and causing injury, effectively protecting the safety of the passengers and ensuring that they can sit stably on the seat 26 when performing the simulated scene without being injured due to the movement of the device.

[0028] Example 2, see Figure 1-Figure 6 On the basis of the first embodiment, a mobile device 3 is arranged on the base 1, and the mobile device 3 includes a first rotating rod 31, and the first rotating rod 31 is rotatably connected to the left side of the inner wall of the base 1 through a bearing. A vertical rod 32 is fixedly connected to the bottom of the box body 21, and a tooth groove 310 is provided on the front of the vertical rod 32. A damper 33 is fixedly connected to the bottom of the inner wall of the base 1, and a spring 34 is provided on the outer wall of the damper 33. The free fall motion of the vertical rod 32 is mitigated by the compression of the spring, so that the passengers can experience a more comfortable and stable feeling during the descent. The characteristics of the compression spring include high elasticity, high thermal conductivity and high durability, which are suitable for long-term operation and repeated use. The spring 34 is a compression spring, which is easy to manufacture and process, has low cost, and can be applied to different shapes, sizes and load requirements, so it has high applicability. The compression spring has a compression force, and the compression spring has the characteristics of high elasticity, high thermal conductivity and high durability. It has high reliability and stability during the working process. Compared with ordinary springs, the design of the compression spring is more compact, and it can exert a greater compression effect in a limited space, saving equipment space.

[0029] A half gear 35 is fixedly sleeved on the outer wall of the first rotating rod 31, and a tooth block 36 is fixedly connected to the outer wall of the half gear 35. The tooth block 36 meshes with the tooth groove 310. A half gear 35 is installed on the outside of the first rotating rod 31, and a tooth block 36 is fixed on its periphery. These tooth blocks 36 mesh with the tooth groove 310 on the front face of the vertical rod 32, so that when the first rotating rod 31 rotates, the vertical rod 32 is driven to move up or down through the action of the half gear 35 and the tooth block 36.

[0030] A limit rod 37 is fixedly connected to the bottom of the box body 21, and the limit rod 37 movably passes through the top of the base 1 and extends to the bottom. A rubber pad 38 is fixedly connected to the bottom of the limit rod 37, and the vertical rod 32 movably passes through the base 1 and extends to the bottom. The function of the limit rod is to limit the moving trajectory of the box body 21 during the lifting process to ensure the stability and safety of the movement. The rubber pad 38 plays a shock-absorbing role as an auxiliary damper 33, further enhancing the stability of the device during operation.

[0031] A motor 39 is fixedly connected to the right side of the base 1, and the first rotating rod 31 movably passes through the base 1 and extends to the right side.

[0032] When the above-mentioned device is used in practice, by starting the motor 39, the motor 39 drives the first rotating rod 31 to rotate, and the first rotating rod 31 drives the half gear 35 to rotate. When the tooth block 36 on the outer wall of the half gear 35 meshes with the tooth groove 310 on the outer wall of the vertical rod 32, the vertical rod 32 is driven to rise, and the vertical rod 32 drives the box 21 and the passengers on the top to rise. At the same time, the limit rod 37 and the rubber pad 38 follow the box 21 to rise. When the tooth block 36 and the tooth groove 310 are no longer meshed, the box 21 falls, and the damper 33 and the spring 34 at the bottom of the vertical rod 32 are used to cushion the free fall of the vertical rod 32. The four limit rods 37 are used to limit the moving trajectory of the box 21. The rubber pad 38 assists the damper 33 in cushioning, so as to drive the passengers on the top of the box 21 to fall freely, fully cooperate with the human body's gravity perception, improve the realism of human-computer interaction, and enhance the sense of immersion.

[0033] Example 3, see Figure 1-Figure 6 On the basis of the first embodiment, a blowing device 4 is provided on the base 1, and the blowing device 4 includes a vertical plate 41, and the vertical plate 41 is rotatably connected to a second rotating rod 42 through a bearing, and the second rotating rod 42 movably penetrates the vertical plate 41 and extends to the left side, and a fan 46 is fixedly connected to the right side of the second rotating rod 42.

[0034] A first belt pulley 43 is fixedly sleeved on the outer wall of the second rotating rod 42 , a second belt pulley 45 is fixedly sleeved on the outer wall of the first rotating rod 31 , and a belt 44 is wound around the outer walls of the first belt pulley 43 and the second belt pulley 45 .

[0035] A step 5 is fixedly connected to the front of the base 1, with two steps in total.

[0036] When the above-mentioned device is used, the first rotating rod 31 drives the first pulley 45 to rotate, the first pulley 45 drives the belt 44 to rotate, the belt 44 drives the second pulley 43 to rotate, the second pulley 43 drives the second rotating rod 42 to rotate, and the second rotating rod 42 drives the fan 46 to blow air to the passengers, thereby enhancing the human body sense and making the user feel immersive, making the virtual reality more realistic.
