Motor-driven 3-DOF (three degrees of freedom) domestic game motion simulator

Abstract

The invention discloses a motor-driven 3-DOF (three degrees of freedom) domestic game motion simulator, comprising a base, a moving platform, a rotary platform, a first rocking mechanism, a second rocking mechanism and a rotary driving mechanism; the moving platform is connected with the base through hooke joint; the first rocking mechanism is fixed to the rear left of the base through a threadedconnector; the second rocking mechanism is fixed to the rear right of the base through a threaded connector; the first and second rocking mechanisms are connected with the moving platform through joint ball bearings; the rotary platform is mounted on the moving platform, and a bearing is mounted between the rotary platform and the moving platform; the rotary driving mechanism is mounted in the moving platform, an output shaft of the rotary driving mechanism is inserted into a shaft bore of the rotary platform, and the rotary driving mechanism is used for directly driving the rotary platform. The motor-driven 3-DOF domestic game motion simulator can rotate around three coordinate axes through driving of a low-power motor, and is simple and compact in structure, low in power consumption, lowin cost, good in simulating effect and suitable for domestic use.

Description

technical field [0001] The invention relates to the technical field of motion simulators, in particular to a motor-driven three-degree-of-freedom home-use game motion simulator. Background technique [0002] The game motion simulator is to track the motion in the virtual game in real time by dynamically controlling the motion simulator, so that the user can get an immersive experience. [0003] Traditional motion simulators are mainly driven by hydraulic pressure or pneumatic pressure, and need external auxiliary facilities such as oil pumps, fuel tanks or high-pressure gas stations. These auxiliary settings not only increase the cost, but also have defects such as oil and gas leakage or noise pollution. Some inventors have proposed improvements, using an electric cylinder as the drive unit. For example, the patent document with application number 201010157797.8 discloses an "electric seat rocking mechanism", which is designed to be driven by an electric cylinder, but the ...

Some inventors have proposed improvements, using an electric cylinder as the drive unit. For example, the patent document with application number 201010157797.8 discloses an "electric seat rocking mechanism", which is designed to be driven by an electric cylinder, but the The mechanism only has two degrees of freedom for swinging and one degree of freedom for lifting, which cannot realize rotary motion and complex motion simulation

[0004] The patent document with the application number 201380044761.0 discloses a "motion simulator" which is also driven by an electric cylinder. Although compared with the former, it can achieve rich motion posture transformation, but the overall structure is very complicated.

The problem with these designs is that because the load during the movement is all on the drive unit, it is necessary to use a high-power drive unit, and the cost is still high

There are certain problems with this design. The swing center in the game is consistent with the center of mass, which leads to the inconsistency between the swing center and the center of the user coordinate system, resulting in simulation distortion

On the other hand, this design has only two real degrees of freedom, and the effect that can be simulated is limited
