Description

Folding rotor wing aerocar

Technical Field

The invention relates to the technical field of aero-automobiles, in particular to a rotor wing type aero-automobile adopting a folding structure.

Background

With the continuous development and progress of automobile manufacturing technology, emerging vehicles, i.e., flying automobiles, which are full of science fiction are also gradually coming into the field of view of people. The flying car is a novel land-air dual-purpose fast traffic tool, is a combination of the car and an aircraft, and mainly adopts a car frame as a main structure and is assisted by a flying mechanism. The novel transportation means mainly takes a land line mode, the flying structure occupies a large space, other vehicles can be influenced and blocked from passing on a road when the novel transportation means is driven on the road without being folded, and the novel transportation means adopts a folding and shrinking structure. The patent application CN218084974U provides a folding wing aerocar, which adopts a rotor structure, and the rotor arm can be folded and retracted. The flying automobile has no rotor wing guard ring and has certain safety problem. The folding structure also needs to have a larger roof assembly space, has certain requirements on the structure and the shape of the roof, and the rotor is not easy to install on a vehicle model with a smaller top area.

Disclosure of Invention

The invention aims to solve the technical problems that: in view of the foregoing, a folding rotorcraft is provided.

The technical proposal of the invention is as follows: the utility model provides a folding rotor aerocar, includes car unit and the flight unit of setting at its top, the flight unit includes base, folding arm and screw, and the base sets up at car unit's top, and folding arm comprises two articulated short arms and the flexible actuating lever of connection between the two mutually, and the short arm of folding arm front end is connected on the base, and the screw setting is at folding arm rear end short arm's free end, flexible actuating lever drive folding arm action, and when expanding, folding arm is "X" form and distributes around the base, and when folding, folding arm rear end short arm that is located the base the place ahead is backward folded, folding arm rear end short arm that is located the base rear is forward folded.

The invention has the technical effects that: the vehicle roof has the advantages of reasonable design, compact structure and high safety, and can be installed on a vehicle roof with smaller top area. The rotor is designed with the retainer, which can improve the safety, and the retainer adopts a combined structure, which can shrink to a certain extent and reduce the space occupation.

Description of the embodiments

As shown in fig. 1 to 4, a folding rotor aerocar comprises a car unit 1 and a flying unit arranged at the top of the car unit, the flying unit comprises a base 2, folding arms 3 and a propeller 4, the base 2 is arranged at the top of the car unit 1, the folding arms 3 are composed of two articulated short arms and a telescopic driving rod 5 connected between the two short arms, the short arms at the front ends of the folding arms 3 are connected to the base 2, the propeller 4 is arranged at the free ends of the short arms at the rear ends of the folding arms 3, the telescopic driving rod 5 drives the folding arms 3 to act, when the folding arms 3 are distributed around the base 2 in an X shape, when the folding rotor aerocar is folded, the short arms at the rear ends of the folding arms 3 positioned in front of the base 2 are folded backwards, and the short arms at the rear ends of the folding arms 3 positioned behind the base 2 are folded forwards. The telescopic driving rod can adopt an electric telescopic rod or a hydraulic cylinder and the like.

The front short arm of the folding arm 3 located at the rear of the base 2 is hinged with the base 2, a abduction telescopic driving rod 6 is arranged between the two short arms, the abduction telescopic driving rod 6 is longitudinally and horizontally arranged and is respectively hinged with the front short arms of the two folding arms 3 at the rear through two connecting rods 7, and two ends of each connecting rod are respectively hinged with the telescopic driving rod and the folding arms so as to drive the front short arms of the folding arms 3 to be outwards unfolded.

The propeller 4 is provided with a retainer 8, and the retainer 8 is connected to the free end of the short arm at the rear end of the folding arm 3 through a bracket.

The retainer 8 is surrounded by four arc-shaped sections, wherein two opposite arc-shaped sections are connected with the folding arm 3 through a telescopic bracket. The telescopic support is composed of two sections, can be driven by an action executing element such as an electric telescopic rod or a hydraulic cylinder arranged in the telescopic support, and can be retracted under the retraction state of the folding arm, so that the occupation of the transverse space of the aerocar can be reduced.

Two short arms of the folding arm 3 are hinged through a hinge plate 9, and the hinge plate 9 is formed by connecting two sheet-shaped bodies into a whole at a certain angle. The hinge plate twisted at a certain angle can provide convenience for staggered stacking of the propellers and the retainers after the folding arms are folded.

The base can be provided with a box-type safety bin, and a safety umbrella used under special conditions is arranged in the bin. The folding arm body is in a certain S shape when unfolded. The folding arm is retracted when the vehicle is in land mode or is resting on land. When the flying vehicle needs to be switched into the flying mode, under the condition that the space environment around the flying vehicle allows, the tail sections of the folding arms are pushed outwards, the guard ring is outwards stretched to form a whole ring, space is reserved for rotation of the blades, and when the four folding arms are completely unfolded, the four folding arms are in an X-shaped state in overlook view, and then the flying mode operation system can be started. In the flying mode, the flying automobile can vertically take off and land at fixed points and can also be lifted up during running in the land mode. The front two of the four propellers provide lift force and assist steering, the rear two of the four propellers provide both lift force and forward thrust, and the adjustable angle of the rear two propellers is larger than that of the front two propellers. When the vehicle flies to the destination and needs to land, the vehicle can select vertical landing or sliding landing according to the environmental condition of the destination, and after the vehicle wheels are contacted with the ground, the flying mode operating system can be closed, and then the folding arm is started to retract. The propeller is driven by unidirectional overrunning, does not need power to generate downward thrust when the propeller passively rotates, and can be combined with the safety umbrella to slow down the falling speed of the aerocar in the air under special conditions.
