Problems solved by technology

[0004] The inventors found that there are still deficiencies in the current aircraft. 1. The existing manned aircraft is only suitable for long-distance flight transportation. Because of its unique structural characteristics, it is not suitable for short-distance ground transportation, thus limiting its scope of use; 2. .The existing manned aircraft has a large overall structure and long wingspan on both sides, which takes up a lot of space when moving on the ground, and is not suitable for ground transportation; 3. The wheel train of the existing amphibious aircraft has a large volume and weight , the structure is relatively complex, resulting in high overall energy consumption, and it is difficult to meet the needs of the aircraft for long endurance

Embodiment 1

[0040] In a typical implementation of the present disclosure, such as Figure 1-Figure 10 As shown, a dual-purpose wheel for land and air is proposed.

[0041] The ground-air dual-purpose wheel includes a rim, a driving arm, a driving mechanism, a propeller and a wheel body, and the propeller and the wheel body are installed on the driving arm. The propeller is located in the rim and coaxially arranged with the rim, and can pass through The airflow generates lift; there are at least three wheel bodies on the driving arm, and they are all tangent to the rim at different positions. At least one wheel body is arranged inside and outside the rim, and at least one wheel body drives the rim around the axis. rotation;

[0042] The position of a circular rim can be determined by the three wheel bodies, so that the position of the rim can be constrained and supported by the three wheel bodies, so that both the wheel body and the rim are in a relatively fixed position.

[0043]The pro...

Embodiment 2

[0065] In another typical implementation of the present disclosure, such as Figure 1-Figure 10 As shown, a ground-air amphibious vehicle is proposed, utilizing the ground-air amphibious wheel as described in embodiment 1.

[0066] The land-air amphibious aircraft mainly includes a frame, a cab, a support arm and land-air dual-purpose wheels, wherein the frame serves as the chassis, the land-air dual-purpose wheels are installed on the chassis through the support arm, and the cab is arranged above the chassis;

[0067] There are multiple groups of dual-purpose wheels arranged at intervals, and each group corresponds to two dual-purpose wheels, which are arranged symmetrically on both sides of the chassis; rear view cameras 15 are symmetrically arranged on the rear end surface of the cab 2;

[0068] Among them, the main function of the chassis 1 is to provide fixed support for the cockpit 2 and the dual-purpose wheels. The cockpit 2 is the driver's cockpit and is equipped with ...

Embodiment 3

[0084] In yet another typical implementation of the present disclosure, such as Figure 1-Figure 10 As shown, a working method of the land-air amphibious aircraft in Embodiment 2 is proposed.

[0085] Include the following steps:

[0086] The indexing of the drive arm 5 on the side of the support arm 3 is controlled by the angle drive motor 504;

[0087] When the corner driving motor 504 controls the driving arm 5 to rotate the wheel rim 10 to a state parallel to the chassis 1, the whole machine is in a flying state;

[0088] The propeller 4 is controlled by the propeller motor 13 to generate reverse thrust, so that the entire aircraft is raised or advanced;

[0089] When the corner driving motor 504 controls the driving arm 5 to rotate the wheel rim 10 to a state perpendicular to the chassis 1, the whole machine is in a walking state;

[0090] At this time, the wheel motor 14 is controlled to make the wheel gear 8 engage with the wheel ring gear 7 to drive, and then the co...

Abstract

The invention provides a land-air dual-purpose wheel and an amphibious aircraft, relating to the field of amphibious aircrafts. The wheel comprises a rim and a driving arm, and a propeller capable ofrotating around the axis is coaxially arranged in the rim; the driving arm is matched with at least three wheel bodies; all the blades are tangent to the rim at different positions; at least one wheelbody is arranged inside the rim and outside the rim respectively; and at least one wheel body drives the rim to rotate around the axis. The walking wheel rim and the propeller are arranged in a combined mode, light weight of the dual-purpose wheel is achieved, switching between the land walking state and the aerial flight state is conducted through the slope rotating structure, the transverse occupied space during ground moving is reduced, the dual-purpose wheel can be better suitable for ground walking, energy consumption is reduced, and the requirement for long endurance of an aircraft is met.

Description

technical field [0001] The present disclosure relates to the field of amphibious aircraft, in particular to an amphibious vehicle and an amphibious aircraft. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Aircraft is a kind of machinery that can fly in the atmosphere or outside the atmosphere. There are many types of aircraft in the prior art. The main function of the commonly used large aircraft is to transport goods or transport passengers. The manned aircraft in the prior art , its production technology is relatively mature, with the characteristics of fast speed and stable flight, which can meet the general needs of use. [0004] The inventors found that there are still deficiencies in the current aircraft. 1. The existing manned aircraft is only suitable for long-distance flight transportation. Because of its unique structural cha...
