Four-degree-of-freedom hybrid cycling simulation platform

Abstract

The invention specifically relates to a four-degree-of-freedom hybrid riding motion simulation platform with two-dimensional movement and two-dimensional rotation; it includes a base, an intermediate actuator, and four drive branches; the intermediate actuator is connected by a pair of first Seat, the first connecting rod, the second connecting rod, the third connecting rod, the fourth connecting rod, the fifth connecting rod and the second connecting seat are sequentially rotated and connected, and the front and rear drive branches all include the U Type kinematic pair, electric cylinder assembly and spherical kinematic pair, the left and right drive branches include electric cylinder assemblies, the telescopic ends of the two electric cylinder assemblies are respectively connected to the second rotating shaft and the sixth rotating shaft, and the two electric cylinder assemblies The fixed ends are rotationally connected with the left and right baffles of the base respectively through the rotating shaft; the eight members have the advantages of simple structure, high precision, strong bearing capacity, small cumulative error at the end and conform to the characteristics of bicycle riding, etc., and can be driven by four sets of electric cylinders Under the interaction of the branches, the two-dimensional rotation and two-dimensional movement of the end are realized.

Description

technical field [0001] The invention belongs to the field of fitness equipment, and in particular relates to a four-degree-of-freedom mixed cycling simulation platform with two-dimensional movement and two-dimensional rotation. Background technique [0002] With the rapid improvement of the economic level and the overall improvement of the quality of life of the people, people have begun to pay attention to how to improve the quality of life. Sports and fitness have become a major goal for people to pursue a healthy life. Under the background of low-carbon sustainable development, the concept of green travel has been deeply rooted in the hearts of the people, and cycling has become popular all over the world. Bicycle riding has become a new choice for people's fitness because of its simplicity, convenience and high interest. However, with the development of the economy, the environment is deteriorating. Frequent haze weather casts a shadow on outdoor cycling. Traffic conges...
