Embodiment Construction

[0033] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0034] "And / or" in this article is just a relationship describing associated objects, which means that there can be three relationships, for example, A and / or B, which can mean that A exists alone, A and B exist at the same time, and B exists alone In these three cases, in addition, the character " / " in this article generally indicates that the associated objects before and after are i...

Abstract

The invention provides a three-degree-of-freedom motion simulator. The three-degree-of-freedom motion simulator comprises a fixed platform, a movable platform, three parallel movement branches which are arranged between the fixed platform and the movable platform, and driving mechanisms corresponding to the movement branches in a one-to-one mode. Each movement branch comprises a first rotating pair arranged on the fixed platform, a first connecting rod connected with the first rotating pair, a second rotating pair arranged on the movable platform and a second connecting rod connected with thesecond rotating pair. The first connecting rod and the second connecting rod are connected through a spherical hinge pair. Each driving mechanism corresponding to each movement branch is arranged on the fixed platform and used for driving the first connecting rod to swing around the first rotating pair. The first rotating pair and the second rotating pair are symmetrical respect to a first plane,wherein the first plane is a plane passing through the center point of the spherical hinge pair of the three movement branches. According to the three-degree-of-freedom motion simulator, the movementof two-rotation and one-movement on the movable platform is realized, thus achieving a high compression ratio and less occupied space.

Description

technical field [0001] The present application relates to the technical field of motion simulators, in particular to a three-degree-of-freedom motion simulator. Background technique [0002] With the continuous popularization of VR equipment, not only the national level pays attention to the development of virtual reality supporting technology, but also the movement simulation of transportation equipment, entertainment simulators, 4D theaters, theme parks and medical auxiliary equipment for new low-cost motion simulation with less degrees of freedom. Devices are also generating huge demand. [0003] The motion simulator receives the motion signal given by the computer by driving the controller, matches it with the motion in the virtual environment and simulates it in real time, so that the users on the motion platform feel a very strong sense of immersion. Most motion simulators are six-degree-of-freedom motion simulators, which are difficult to miniaturize and are not cond...
