A land-air amphibious vehicle

Abstract

The invention discloses a ground-air amphibious vehicle, which comprises a vehicle body base, a power mechanism, a transmission mechanism and a drive assembly. The power of the power mechanism is driven by the transmission mechanism to drive the drive assembly. On the body base, it can fly in the air by overcoming air resistance and its own gravity or travel on the ground by overcoming ground friction. The beneficial effects of the present invention are: the flight propeller and the running assembly are combined into a deformable wheel wing assembly, and the power drives the running assembly to move at a low speed when driving on the ground; when flying in the air, the wheel wing assembly is deformed by the steering gear , so that the plane of rotation of the flying propeller is located in the horizontal plane, at this time the power is transmitted to the flying propeller through the transmission mechanism to make the flying propeller rotate at a high speed to provide lift.

Description

technical field [0001] The invention relates to a vehicle, in particular to a land-air amphibious vehicle. Background technique [0002] With the vigorous development of computer technology, communication technology and electronic technology, the research on automotive aircraft has gradually formed an upsurge in the world, but it is still in the design concept stage, and many technical problems are still difficult to solve. Compared with helicopters, fixed-wing aircraft has the advantages of high flight efficiency, fast flight speed, long flight distance, simple system structure, light weight, low cost and use fee, etc., but fixed-wing aircraft also has its own inevitable defects, that is, in Takeoff and landing require taxiing or use of special launch recovery devices. [0003] Vertical take-off and landing technology makes it possible for aircraft to combine the performance and advantages of helicopters and fixed wings. At present, the more successful vertical take-off a...

Problems solved by technology

But through its patent application specification, we can't find its specific technical solution. It can be seen from the accompanying drawings of the specification that the structure of the flying car is unreasonable, and its main weight is concentrated on the front wheel of the bicycle. Once the engine fails, there are no preventive measures , very dangerous

French patent FR1265234 discloses a vehicle that can both drive on the ground and fly, but its structure is relatively simple and cannot meet the needs of multi-purpose

Chinese patent CN103350624A discloses a vehicle that can drive on the ground and fly, but its ground driving structure and flight structure are relatively simple and rough superimposed forms, which are not fully, effectively and reasonably integrated, and the propeller is not protected. During the flight, the propeller rotates at a high speed. Once it encounters obstacles or people, it is easy to cause damage to itself or endanger people's life safety.

[0006] Based on the research of existing literature and existing related technologies, the inventors found that the flying cars reported or realized at home and abroad are basically fixed wings, which require a fixed runway, which greatly limits their application occasions

The existing methods for implementing the helical wing are basically in the theoretical stage, and the helical wing is huge, which is not conducive to practical application

There is no one feasible way to implement
