Description

Wind-driven dry sail recreational vehicle

Technical Field

The invention relates to a wind-driven traveling vehicle technology, in particular to a Gobi wind-driven dry sail recreational vehicle.

Background

In 1600 years, simon steifen, the netherlands, based on the principle that sailboats travel by wind propulsion, created a "double-mast sailing vehicle" with a maximum speed of up to 24 km per hour in the seaside test. The sail vehicle is actually provided with four wheels on a sailing boat, or a mast on a carriage.

At present, wind sailing vehicles at home and abroad pay attention to the fact that the design of a wind sail and the arrangement of the wind sailing vehicle are more, and the corresponding frame structure, the wheel train design and the damping are less.

With the development of tourism industry in China, desert and Gobi tourism is increasingly favored, the Gobi is as wide and flat as the sea, but how to develop the Gobi into a novel tourism resource, the development design of tourism experience instruments is crucial, and currently, known related technologies are few; meanwhile, in the field of dry sails, the existing sail vehicle is designed to be mostly aimed at the field of travel tools, and is low in practicability and safety.
