It can provide a real sports environment and sports data, allowing users to conduct sports training, competition or entertainment activities in a virtual scene.

[0003] Sea shooting has higher requirements for shooting skills due to many external difficulties such as strong winds, high waves, and shaking boats. Compared with land shooting training, sea shooting training needs to simulate the impact of real waves on body balance. However, general motion simulation platforms have low degrees of freedom and flexibility, and the real feeling when simulating the wave environment is poor, which will affect the simulation effect of sea shooting. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that sea shooting training needs to simulate the influence of real waves on body balance compared with land shooting training, while the freedom and flexibility of general motion simulation platforms are low, and the real feeling when simulating the wave environment is poor, which will affect the simulation effect of sea shooting, and a six-degree-of-freedom motion simulation platform is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A six-degree-of-freedom motion simulation platform comprises a chassis, a support column is fixedly connected to the center of the chassis, a support ball is fixedly connected to the top of the support column, a universal seat is provided on the outer movable sleeve of the support ball, a simulation table is fixedly connected to the top of the universal seat, a PLC controller is fixedly connected to the side wall of the chassis, six cylinders are fixedly connected to the inner wall of the bottom end of the chassis, six guide rails are fixedly connected to the bottom of the simulation table, guide blocks are slidably provided on the inner walls of the six guide rails, and the piston rod ends of the six cylinders are respectively hingedly provided at the bottom of the six guide blocks.

[0007] Preferably, a damping pad is fixedly connected to the inner wall of the universal seat, and the inner wall of the damping pad is fitted on the side wall of the supporting ball.

[0008] Preferably, a spherical groove is opened on the side wall of the simulation table, and a ball is rolled on the inner wall of the simulation table located in the spherical groove. The inner wall of the chassis is set as an arc surface, and the ball is rolled on the inner wall of the chassis located on the arc surface.

[0009] Preferably, a guardrail is fixedly connected to the top of the chassis.

[0010] Preferably, a strap is hingedly provided at the top end of the simulation platform, and a bolt is threadedly connected to the connection between the strap and the simulation platform.

[0011] Preferably, the cross section of the guide block is set to be trapezoidal, and the inner wall of the guide rail matches the guide block.

[0012] Compared with the prior art, the utility model provides a six-degree-of-freedom motion simulation platform, which has the following beneficial effects:

[0013] 1. The six-degree-of-freedom motion simulation platform controls the piston rods of the six cylinders through a PLC controller to perform flexible extension and retraction, so that the simulation platform can simulate waves. The simulation platform rotates along the surface of the supporting ball through the universal seat to ensure that the simulation platform maintains good stability during simulation. The damping pad increases the friction between the universal seat and the supporting ball, improves the stability during adjustment, and pushes the guide block to slide along the inner wall of the guide rail when the piston rod of the cylinder is extended and retracted, ensuring the stability of the transmission between the cylinder piston rod and the simulation platform.

[0014] 2. The six-degree-of-freedom motion simulation platform uses balls to roll along the inner wall of the chassis to reduce the friction on the inner wall of the chassis when the simulation platform swings. The guardrail can improve the protection effect and prevent people from falling out of the chassis.

[0015] 3. The six-degree-of-freedom motion simulation platform is fixed on the surface of the simulation table by bolts through a strap, which can improve the stability of the feet on the simulation table. The cross-section of the guide block is set to be trapezoidal and the inner wall of the guide rail matches the guide block, which can improve the stability of the guide block sliding inside the guide rail.
