[0002] An omnidirectional treadmill is a device that allows users to move freely in a virtual reality environment. This treadmill simulates the steps of real walking or running, allowing users to move 360 ​​degrees in a limited physical space. Unlike traditional treadmills, omnidirectional treadmills are usually equipped with sensors and tracking systems that can accurately capture the user's movements and convert them into corresponding action sequences in the VR environment. Therefore, an array omnidirectional treadmill is needed.

However, when using it, the person often needs to wear designated equipment to achieve the effect of reducing friction. When the friction between the two needs to be reduced, it often leads to the impact on the output of the equipment. For this reason, we propose an array-type omnidirectional treadmill.

[0025] like Figure 1-Figure 7 As shown, an array type omnidirectional treadmill includes a running platform 1 and a driving assembly 8, wherein a fixed platform 4 is bolted to the top of the running platform 1, and a supporting assembly 5 is arranged to the top of the fixed platform 4, a placement chamber 6 is arranged at the center of the fixed platform 4, and a placement box 7 is placed below the inner wall of the placement chamber 6, the driving assembly 8 is arranged below the inner wall of the placement box 7, and a rotating disk 9 is installed at the top of the driving assembly 8, a position sensor 901 is installed at the top of the rotating disk 9, and a force feedback sensor 902 is engaged at the center of the position sensor 901, and the position sensor 901 and the force feedback sensor 902 are both installed on the supporting disk 903, wherein the sportsperson moves to the top of the running platform 1, opens the retaining ring 2 of the supporting assembly 5, and thus enters the retaining ring 2, and closes the retaining ring 2, so that when the sportsperson moves subsequently, the supporting assembly 5 itself protects the sportsperson when moving. The model of the position sensor 901 is: DSF2210.00 SHV, and this type of sensor is used to determine the position and direction of the user in the virtual environment. In an omnidirectional treadmill, users can move their legs in a plane of degrees to provide complete freedom of directional movement. This type of equipment can utilize accessories such as haptic suits to promote full-body interaction. Force feedback sensor 902 model: Omega.3 Force feedback sensor 902 is a device that can detect force and torque. They can convert physical force into electrical signals, which can then be read and analyzed by computers or other devices.

[0026] The driving assembly 8 includes a rotating disk 9, a connecting assembly 10, a connecting shaft 11, a gear box 12, an output shaft 13 and a bidirectional rotating motor 14, and the bottom end of the rotating disk 9 is connected to the connecting assembly 10, the connecting shaft 11 is engaged with the side of the connecting assembly 10 away from the rotating disk 9, and the gear box 12 is connected to the side of the connecting shaft 11 away from the connecting assembly 10, the output shaft 13 is provided on the side of the gear box 12 away from the connecting shaft 11, and the bidirectional rotating motor 14 is provided on the side of the output shaft 13 away from the gear box 12. When the athlete is inside the supporting assembly 5 and steps on the fixed platform 4 above the treadmill 1, the position sensor 901 and the force feedback sensor 902 at the rotating disk 9 on the outer surface of the fixed platform 4 continuously receive records about the movement of the athlete, so that the driving assembly 8 drives the rotating disk 9 to rotate, wherein the bidirectional rotating motor 14 receives the signal of the position sensor 901 , thereby rotating, so that the output end of the bidirectional rotating motor 14 drives the output shaft 13 and the clamping block 1301 connected to the output shaft 13 to rotate, and the clamping block 1301 is a block connecting the output shaft 13 and the bidirectional rotating motor 14. When the output shaft 13 rotates, it drives the gear inside the gear box 12 connected to the top of the output shaft 13 to rotate. At the same time, the gear is used to increase the output torque of the motor and reduce the rotational inertia during the rotation process, thereby improving the dynamic response speed of the system to reduce the lag of the motor reaction. When the gear box 12 rotates, it drives the rotating disk 9 connected to the gear box 12 to rotate. At the same time, the gear box 12 rotates the rotating disk 9 through the connecting shaft 11 and the connecting assembly 10. At the same time, due to the detachability of the connecting assembly 10, when the rotating disk 9 needs to be replaced, the rotating disk 9 body can be directly disassembled.

[0027] The connecting component 10 includes a connecting tube 1001 and a connecting column 1002, and the connecting column 1002 is connected to the center of the inner wall of the connecting tube 1001. A rotating structure is formed between the rotating disk 9 and the connecting shaft 11 through the connecting component 10, wherein the connecting tube 1001 is installed on the rotating disk 9, and the connecting column 1002 is installed on the connecting shaft 11.

[0029] A clamping block 1301 is provided at the center of the output shaft 13 and the bidirectional rotating motor 14, and grooves 1401 are provided on the four sides of the bidirectional rotating motor 14, and the supporting assembly 5 includes a retaining ring 2 and a supporting bracket 3, and the supporting bracket 3 is installed under the retaining ring 2. When the bidirectional rotating motor 14 is placed in the base 701 under the placement box 7, the groove 1401 provided by the bidirectional rotating motor 14 can make the positioning bar 702 on the inner wall of the base 701 merge with the groove 1401, thereby increasing the impact force on the bidirectional rotating motor 14 itself.

[0030] A base 701 is provided below the placement box 7 , and positioning strips 702 are provided on four sides of the inner wall of the base 701 .

[0031] In summary, the utility model uses a treadmill 1 and a driving assembly 8. When an athlete steps on the treadmill 1, the baffle ring 2 of the support assembly 5 is opened, the athlete places the waist inside the baffle ring 2, and the baffle ring 2 is closed, so as to limit the position of the athlete above the treadmill 1. When the equipment is started, the rotating disk 9 below the treadmill 1 is stepped on by the athlete. At this time, when the driving assembly 8 below the rotating disk 9 receives signals from the position sensor 901 and the force feedback sensor 902, when the position sensor 901 on the side of the rotating disk 9 is covered by the sole of the foot, the position sensor 901 feeds back the signal to the driving assembly 8, and the bidirectional rotating motor 14 inside the driving assembly 8 rotates clockwise or counterclockwise toward the covered position sensor 901 area, and the output shaft 13 connected to the bidirectional rotating motor 14 drives the gear box 12 to rotate, and the gears inside the gear box 12 are used to increase the output torque of the motor and reduce the moment of inertia, thereby improving the dynamic response speed of the system. By selecting gears of different sizes, the speed and torque of the motor can be adjusted to adapt to different load requirements, so that the gear box 12 drives the connecting shaft 11 and the connecting component 10 to rotate, thereby feeding back to the upper part of the rotating disk 9 connected to the connecting component 10, so that the rotating disk 9 drives the athlete to rotate, and when the rotating disk 9 under the sole of the foot is in motion, it drives the sole of the foot to continuously move backward. At the same time, when the sole of the foot is in motion, the movement of the rotating disk 9 allows the athlete to simulate a real sports scene.
