This patent application claims the benefit and priority of Chinese Patent Application No. 202110861584.1, filed on Jul. 29, 2021, the disclosure of which is incorporated by reference herein in its entirety as part of the present application.
The present disclosure relates to the technical field of virtual reality (VR) omni-directional machines, and in particular relates to a VR omni-directional exercise machine with a terrain environment simulation function.
Virtual reality (VR) refers to a technology that may combine a virtual environment with a real environment, or generate an entirely virtual environment. In theory, VR is a computer simulation system capable of creating a virtual world for a user to experience by generating a simulated environment using the computer, thus causing a user to immerse himself in the environment. VR is an electronic signal generated by utilizing data in real life through a computer technology, which is combined with various output devices to be converted into phenomena capable of being perceived by people. Such phenomena may represented as real objects as well as substances incapable of being seen by the naked eye, and are represented by a three-dimensional model. These phenomena are referred to as virtual reality because they are the real world simulated by the computer technology rather than what can be seen directly.
The VR technology has started to combine with the omni-directional treadmill technology in recent years, and the combination of the two has been used in the gaming field. People can immerse themselves in the VR world by combining the VR technology on the treadmill.
At present, the VR treadmill on the market can only mechanically complete some simple exercises and cannot simulate ground conditions of the virtual reality environment, leading to reduction of the sense of reality.
For the problems in the prior art, a VR omni-directional exercise machine with a terrain environment simulation function is provided, through which a user can do exercises with high degree of difficulty, such as stair climbing, climbing and jumping, on a platform.

In the drawings:
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.
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.
A linear slide 5 is arranged on a sidewall of protective ring supporting column 6, a first pressure sensor 20 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 20 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 21 and a damping inductor 22 which are both connected to the control machine. After the acquired pressure data is fed back to the control machine through the damping inductor 22 and the force-controlled sensor 21, 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
As shown in
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.
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.
The above is only the preferred embodiment of the present disclosure, and the scope of protective of the present disclosure is not only limited to above embodiments, and all technical solutions belonging to the idea of the present disclosure belong to the scope of protective of the present disclosure. It should be noted that for those skilled in the art, various improvements and modifications without departing from the principles of the present disclosure should be deemed to be within the scope of protective of the present disclosure.
