A roller array active omnidirectional treadmill

Abstract

The invention discloses an active roller array omni-bearing treadmill. The active roller array omni-bearing treadmill comprises an array type drive assembly (1), a power system (2), a steering system (3), a walking platform (4) and a frame (5). The active roller array omni-bearing treadmill is characterized in that the drive assembly (1) comprises a power wheel (1.1) and a steering wheel (1.2); the power wheel (1.1) is provided with a rotary shaft (1.3), the rotary shaft (1.3) is provided with a first bevel gear (1.4), a frame body (1.5) is provided with a main roller (1.6) and an auxiliary roller (1.7), the main roller (1.6) is provided with a second bevel gear (1.8) engaged with the first bevel gear (1.4), and the bevel direction of the first bevel gear (1.4) is downward. The rotating speed of the main roller cannot deviate from a preset value through the bevel gears of the drive assembly of the omni-bearing treadmill, steering motion and horizontal motion of the drive assembly are independent and controllable, reliability is high, the mass of the assembly is low, replacement is convenient, inertia of a system is small, and flexibility is high.

Description

technical field [0001] The invention relates to an interactive device for virtual reality sports, in particular to a roller array active omnidirectional treadmill. Background technique [0002] Virtual reality technology is a new display technology. It can simulate a more realistic three-dimensional environment, which is displayed through a virtual helmet. After wearing a virtual reality helmet, although the virtual picture can be displayed, the movement in the real environment is more effective. This will greatly weaken the immersion of the user experience fun. If an interactive device that can move freely can be invented to combine sports and entertainment, then the fun of experiencing virtual reality will be greatly improved. Therefore, the omnidirectional treadmill is produced, and the omnidirectional A treadmill refers to a type of treadmill that provides users with horizontal and arbitrary directions of movement, and the speed and direction of the movement can be chang...

AI Technical Summary

Problems solved by technology

[0005] The schemes of the active omnidirectional treadmill are as follows: firstly, the nesting direction of the large conveyor belt is vertical to that of the small conveyor belt, which has the advantage of easy control, and only needs to control the movement speed of the conveyor belt in two directions to form a combined speed in any horizontal direction; The disadvantage is that the system inertia is relatively large. Since the small conveyor belt system is installed on the large conveyor belt as a whole, the large conveyor belt has too much rotational inertia, so it lacks flexibility; the second is to use several motors to drive the screw device, and this solution has better linear motion synchronization , but the disadvantage is that it cannot match the user's movement direction and movement speed in time
