DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] To further illustrate the technical solution and the working principle disclosed herein, the present disclosure is introduced in detail below with reference to the accompanying drawings and specific embodiments. The orientation descriptions used herein are those in conjunction with the drawings and can be understood by those skilled in the art.

[0019] FIGS. 1 and 2 show a structure diagram of a VR omni-directional exercise machine with a terrain environment simulation function of the present disclosure. The VR omni-directional exercise machine comprises a protective ring 1, protective ring supporting rods 4, protective ring supporting columns 6, an exercise platform 7, a control machine 18, and a VR head-mounted display. Protective ring 1 is arranged above the exercise platform 7, and is connected to the protective ring supporting columns 6 through the protective ring supporting rods 4. Protective ring 1 may follow a user while moving up and down along the protective ring supporting columns 6 that play a role in protecting and supporting, i.e., the bottoms of protective ring supporting columns 6 are fixedly connected to the outer side of the exercise platform 7. A moving vertical rod module lattice 16 is arranged in the exercise platform 7, and the moving vertical rod module lattice 16 and the VR head-mounted display are both connected to control machine 18 which is used to coordinate and control the movement of the moving vertical rod module lattice 16 according to a terrain environment displayed in the VR head-mounted display 17, thus making the user feel the change of the terrain environment on the VR omni-directional exercise machine. Data of an exercise plane is latticed by arranging the moving vertical rod module lattice 16, and each moving vertical rod module in the moving vertical rod module lattice 16 can move up and down to provide an operable platform for various exercise modes such as walking, running, jumping, and stair climbing in 360 degrees, thus making the environment consistent with the body perception. The control machine 18 is used to coordinate and control the moving vertical rod module lattice 16 such that the movement data of various moving vertical rod modules are integrated, and each moving vertical rod module can be accurately controlled through a big data cloud computing technology. In this way, the terrain environment, even a complex terrain environment, can be simulated. A user wears the VR head-mounted display 17 in front of the user's eyes while exercising, the VR head-mounted display 17 is used to display an exercise environment that is more immersive. Moving vertical rod module lattice 16 may do corresponding movement according to the environment condition under different exercise environments.

[0020] The protective ring 1 is provided with a rotating pulley and an inner protective net. The rotating pulley is embedded onto the protective ring 1, and the inner protective net is fixedly connected to a sidewall of the protective ring 1. The user puts the protective ring 1 on the waist from top to bottom and fixes the protective ring through the inner protective net which is composed of an elastic net-shaped material and a safety belt and can relieve the pressing feeling of the protective ring 1 on a human body when the user moves. Due to the characteristics of being small in friction force, easy to slide, safe and reliable, the rotating pulley can achieve the 360-degree exercise function of the user, and the user actively exercises to drive the rotating pulley to move, thus completing the exercise of steering and angle-turning.

[0021] A linear slide 5 is arranged on a sidewall of protective ring supporting column 6, a first pressure sensor is arranged on a contact face of the linear slide 5 and the protective ring supporting column 6, and the linear slide 5 is connected to the protective ring supporting rod 4. The protective ring supporting rod 4 not only can play a role in supporting the user, but also can protect the safety of the user. A first pressure sensor is arranged on the linear slide 5 to acquire pressure data in the protective ring supporting rod in real time when the user moves, and the data is fed back to the main control module 14 in the moving vertical rod module lattice 16, thus the VR exercise machine can correct the own movement state in time through data analysis. The protective ring supporting rod 4 is provided with a force-controlled sensor and a damping inductor which are both connected to the control machine. After the acquired pressure data is fed back to the control machine through the damping inductor and the force-controlled sensor, the VR exercise machine can adjust the damping of the linear slide 5 in real time to guarantee the real experience feeling of the user in exercise and to ensure the safety of the user. Linear slides 5 may be used on all three protective ring supporting columns 6 as shown. In addition, more or fewer protective ring supporting columns 6 than shown in FIGS. 1 and 2.

[0022] As shown in FIG. 3, a structure diagram of a moving vertical rod module of the present disclosure is provided. Each moving vertical rod module in the moving vertical rod module lattice 16 comprises a small moving ball 8, an electromagnetic ring 9, a moving lead screw 10, a motor motion module 11, a movable sleeve 12, a supporting sleeve 13, a main control module 14, and a battery module 15. Movable sleeve 12 is nested in the supporting sleeve 13, while the battery module 15, the main control module 14 and the motor motion module 11 are sequentially connected to the interior of the supporting sleeve 13 from bottom to top. Moving lead screw 10 is arranged in the movable sleeve 12 and connected to the motor motion module 11, and the electromagnetic ring 9 is arranged above the moving sleeve 12. The motor motion module 11 in the present disclosure has the features of being fast in reaction speed and accurate in movement control; the moving lead screw 10 in the movable sleeve 12 is driven by the motion module 11 to move to drive the electromagnetic ring 9 to move up and down; the small moving ball 8 is embedded into the electromagnetic ring 9, and the electromagnetic ring 9 is connected to the main control module 14. The small moving ball 8 in the present disclosure is of a hollow structure, when the small moving ball 8 is in contact with the feet of the user, a magnetic force is provided by the electromagnetic ring 9, and the main control module 14 is used to control the magnetic force, thus controlling the contact condition of the small moving ball 8 and the feet of the user and simulating the terrain condition perceived by the user. A second pressure sensor is arranged on the electromagnetic ring 9, and the small moving ball 8 above the electromagnetic ring 9 is to be in contact with the user directly. By arranging the second pressure sensor, the pressure data on the small moving ball 8 when the user moves can be acquired in real time, and then the pressure data is fed back to the main control module 14, thus the VR exercise machine can adjust the movement state in time according to data analysis.

[0023] The working process of the VR omni-directional exercise machine is specifically as follows: the user enters the exercise platform 7 and puts the protective ring 1 on the waist from top and fixes the inner protective net 3, and then the user can turn the body in any angle and simply walk in situ to adapt to the exercise platform 7. After finishing pre-exercise preparation, the VR omni-directional exercise machine is started, the user wears the VR head-mounted display 17 which may present real-time game graphics and a 3D-effect space, ground conditions including but not limited to level roads, mountain roads, grass, rocks, stairs, and the like. When the user moves in the virtual space, the VR omni-directional exercise machine can make corresponding changes along with the ground conditions in the virtual space. When the user enters a stair environment, the moving vertical rod module under the feet stays unchanged, the small moving ball 8 in the moving vertical rod module is also kept in a stable state through the magnetic force control of the electromagnetic ring 9, thus the small moving ball does not have sliding force. The moving vertical rod module in an advancing direction of the user moves upwards to simulate the stair environment, and when the moving vertical rod module rises, the small moving ball 8 in the moving vertical rod module is also kept in a stable state under the magnetic attraction of the electromagnetic ring 9 while the stability of the moving vertical rod module is guaranteed. Thus the small moving ball does not have the sliding force effect; when the user advances to the moving vertical rod module right ahead, the moving vertical rod module moves downwards to a horizontal plane of the exercise platform 7, the electromagnetic ring 9 below the small moving ball 8 no longer have the magnetic force effect, and the small moving ball 8 has the sliding force effect, thus completing the exercise in the advancing direction. Therefore, the movement unit of one stair is completed, and by repeating the movement unit, the user can achieve the exercise in the stair environment. When the user enters a level road environment, the moving vertical rod module no longer moves up and down, the user is only assisted by the small moving ball 8 to move on the level road, and the magnetic data is accurately controlled by the small moving ball 8 through the electromagnetic ring 9, thus guaranteeing that the user does not feel smooth or rough when doing exercise on the exercise platform.

[0024] The VR omni-directional exercise machine disclosed by the present disclosure solves the problem that an existing VR treadmill cannot simulate the ground environment in the virtual world, can achieve a series of exercise modes such as walking, running, jumping, crouching, stair climbing and the like in 360 degrees, and has the features of being safe, reliable, reasonable in structure, and high in science and technology feeling.
