Embodiment Construction

[0017] Below in conjunction with accompanying drawing and embodiment the technical scheme of a kind of cross-country skiing simulator pneumatic control system that the present invention proposes is described in detail.

[0018] The pneumatic control system of a cross-country skiing simulator proposed by the present invention has two mutually symmetrical and independent pneumatic control subsystems. The pneumatic control subsystems have the same structure, and the pneumatic control subsystem on one side is taken as an example to illustrate.

[0019] see Figure 1~3 , one side of the pneumatic control subsystem includes a mechanical rodless cylinder 10, an air source unit 90 and a back pressure control module 40; The reciprocating motion of the piston and the slide table 100 along the axial direction of the cylinder cavity simulates the relative motion between the human body and the drop point of the strut during skiing, and in the initial state, the piston of the mechanical rod...

Abstract

The present invention proposes a pneumatic control system for a cross-country skiing simulator, which includes two sets of pneumatic control subsystems, each of which includes a mechanical rodless cylinder, an air source unit and a back pressure control module; The air port forms the main branch circuit through the pipeline provided with T-shaped three-way joint, pressure reducing valve and three-position five-way solenoid valve in sequence. Chamber air supply branch, the air outlet of the air source unit forms a back pressure control branch after passing through the T-shaped tee joint; the mechanical rodless cylinder is connected with the front chamber air supply / exhaust branch, the rear chamber air supply branch, The back pressure control branch is connected with the rapid exhaust branch; the side wall of the mechanical rodless cylinder is provided with a plurality of magnetic switches in contact with the magnetic ring of the piston in the cylinder. The invention applies the characteristics of pneumatic transmission to the cross-country skiing simulator, and realizes the quick and automatic return of the piston through the pneumatic drive, so that the whole process simulation of the cross-country skiing action can be realized.

Description

technical field [0001] The invention relates to the technical field of skiing simulators, in particular to a pneumatic control system for a cross-country skiing simulator. Background technique [0002] Cross-country skiing is a snow event that requires extremely high physical fitness, known as "snow marathon". Among them, cross-country skiers need to stand on a pair of skis and slide with poles; for seated cross-country skiers, they need to equip a sit-type ski on a pair of skis, and disabled athletes sit on the skis and rely on upper body strength to support. pole glide [0003] Common cross-country skiing simulators currently on the market, such as patent US8986167 (United States, Announcement Date: 2015.03.24) provide a training equipment that imitates cross-country skiing. Cross-country ski pole resistance. When the device is in use, the bottom tip of the ski pole needs to be attached to the slider on the guide rail. During the return trip, the ski poles cannot be li...
