Embodiment Construction

[0056] The column element array omnidirectional treadmill includes a walking platform and an array omnidirectional drive assembly. The key to realizing the omnidirectional drive assembly is to realize the independent control of the rolling and steering of the working roller (7) at the same time, and to prevent the coupling effect of the two movements , resulting in speed imbalance. In this example, the omnidirectional drive assembly is used as figure 1 Column element (1) form shown. The column element (1) includes two sets of gear transmission systems, one is the working transmission system, the main power wheel (2) drives the power input wheel (4), drives the coaxially connected bevel gear (5), and drives the rolling gear (6 ), and finally drives the working roller (7) to move, and the rotating shaft is converted from vertical to horizontal during the transmission process, which provides power for the rolling of the working roller (7); the other set is the steering transmiss...

Abstract

A column-element array type omnidirectional treadmill comprises walking decks and an array type omnidirectional driving component and can be applied to providing an unlimited free walking space for a user in a virtual realistic field. A column-element array structure is adopted for the omnidirectional driving component which is small in turning inertia, unlimited in radius of turning circles and capable of accurately and quickly following movement of the user and simulating various complex terrains. In a transmission process, external input power is converted into horizontal driving force by work transmission systems of column elements, so that working power is provided; turning movement of a working part is controlled by turning transmission systems of the column elements, so that the working part is enabled to match with the user in a forwarding direction. The working power and the turning power of the column elements is provided externally. Via mutual splicing of the walking decks which are different in height and inclining angles, walking movement in various complex terrains and movements in going up and down stairs can be simulated. By means of combining arrays by a plurality of column elements in different height, various complex three-dimensional structures on the ground can be simulated.

Description

technical field [0001] The invention relates to an omnidirectional treadmill, also known as ODT (Omnidirectional treadmill), which can be used in the field of virtual reality to provide users with unlimited free walking space in a limited actual space, especially relates to a treadmill that can simulate complex terrain And a three-dimensional omnidirectional treadmill that moves up and down steps. Background technique [0002] Omnidirectional treadmill, known internationally as ODT, refers to a type of treadmill whose horizontal movement direction can change with people's steps, and it can provide indoor users with unlimited free walking space. [0003] At present, there are many ODT schemes in the world. [0004] One is the "Cyberwalk" plan, which adopts the method of nesting a large conveyor belt with a vertical small conveyor belt. The advantage is that it is easy to control. It only needs to control the moving speed of the conveyor belt in two directions to form a combi...
