Description

Technical Field

[0001] The invention relates to the technical field of flying vehicles, in particular to a land-air dual-purpose vehicle. Background Art

[0002] In today's era, the global economy is showing a booming trend of rapid development, and people's living standards are constantly improving. Cars, as a convenient means of transportation, have entered thousands of households, and their ownership is rising sharply at an unprecedented rate. This phenomenon has directly led to an increasing number of cars on the road, and traffic congestion has become more and more serious, which has become a major problem hindering the further development of cities.

[0003] In the streets and alleys of the city, especially during rush hours in the morning and evening, the roads are densely packed with cars forming long queues. Scenes of difficulty in moving can be seen everywhere. Vehicles can only move as slowly as snails. A journey that originally took just a dozen minutes often takes several times or even dozens of times longer to complete. The negative impact of traffic congestion is far more than just an increase in travel time. It also produces extremely adverse chain reactions at many critical moments.

[0004] Faced with such severe traffic conditions, the highly innovative concept of flying cars came into being, bringing a new idea to solving the problem of urban traffic congestion. Flying cars have unique and powerful functions. They can flexibly choose to fly in the air or drive on land according to actual needs, and easily achieve a seamless transition from an ordinary road car to an airplane. When the road is unobstructed, it can run smoothly on the road like a traditional car. Once it encounters traffic difficulties such as traffic jams, it can quickly switch to flight mode to avoid congested sections, open up an air channel of its own, and quickly reach its destination. In this way, it can not only effectively alleviate the pressure of ground traffic, but also ensure that special vehicles are no longer troubled by traffic jams when performing emergency tasks, and play their due role in a timely manner to safeguard the efficient operation of the city and the safety of people's lives and property.

[0005] However, the existing devices have the following problems:

[0006] When traditional flying cars are flying, due to their structural layout, the driver's line of sight is blocked, resulting in the driver being unable to obtain a good field of vision to ensure flight safety and accurately judge the flight environment, making it inconvenient and uncomfortable for people to travel in flying cars. Summary of the invention

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-4, including a car body 1, the car body 1 is connected with a connecting rod shaft 2, the connecting rod shaft 2 is connected with a connecting rod 3, the connecting rod 3 can be retracted, the connecting rod 3 is attached with a lifting body, one end of the connecting rod 3 is provided with a propeller shaft 4, the propeller shaft 4 is connected with a propeller 5, the propeller 5 adopts a variable pitch propeller, the lower end of the propeller 5 is provided with a blade that can change the lift direction, and the outer side of the propeller shaft 4 is provided with a lifting body; the connecting rod shaft 2 is connected to the car body 1, and plays the role of connecting the car body 1 and the connecting rod 3, so that the connecting rod 3 can be flexibly rotated relative to the car body 1, so as to adjust the angle and orientation of the lifting body and the propeller 5, so as to adapt to the aerodynamic requirements under different flight conditions; the connecting rod 3 is also retractable and can change its own length according to actual flight requirements, so as to flexibly adjust the spatial position of the lifting body and the propeller 5, increase The propeller shaft 4 is connected to the connecting rod 3 and the propeller 5, so that the propeller 5 can rotate around it. It is a key rotating component for realizing the propeller 5 to generate lift and push the car to fly in the air. At the same time, the angle direction of the propeller 5 can be changed by rotation. In conjunction with the flight attitude adjustment operation, the propeller 5 adopts a variable pitch propeller design, which can generate enough lift when rotating at high speed, so that the car can leave the ground and fly in the air. The lower end of the propeller 5 is provided with a blade that can change the lift direction. By changing the angle of the blade, the lift size and direction can be adjusted, and the flight height, speed and flight attitude can be flexibly controlled to ensure the stability and controllability of the flight process. This increases the flexibility of the entire flight system layout, and the position can be reasonably adjusted according to specific flight performance requirements and space utilization.

[0031] See also Figure 1-4 The propeller 5 adopts a propeller with a swinging hinge. The propeller 5 with a swinging hinge can accurately fine-tune the lift direction, so that the propeller can maintain good efficiency at different speeds. The propeller 5 is provided with a protective cover. The protective cover of the propeller 5 can effectively separate the dangerous propeller 5 from people and other objects, and also play a role in restricting airflow. The car body 1 has a counterweight for adjusting the center of gravity. The counterweight can adjust the change of the center of gravity position of the people and cargo in the car. The rear end of the car body 1 is provided with a tail wing for increasing stability. During the flight, due to the impact of high-speed airflow, adding a tail wing can better control the flying car. Placing propellers in the front and rear compartments of the car body 1 can also increase lift. Adding a lift body structure at the end of the propeller shaft 4 can increase lift. The number of blades of the propeller 5 is not limited to adapt to different load requirements.

[0032] To sum up, when the land-air dual-purpose vehicle is in use, the driver operates the vehicle body 1 like operating an ordinary car. When it is necessary to switch to flight mode, the driver first parks the vehicle in a suitable open space to ensure that the surrounding environment is safe and meets the take-off conditions. Then, by controlling the connecting rod shaft 2 and the propeller shaft 4, the connecting rod 3 and the propeller 5 that were originally stored are gradually opened, and according to actual flight needs, the telescopic function of the connecting rod 3 is used to adjust its length to a suitable position, and the propeller 5 is placed at a suitable position on the connecting rod 3 to prepare the spatial layout for the subsequent generation of lift. The propeller 5 is started and starts to rotate at a high speed under power drive. Sufficient lift will be generated during rotation, and the blade angle of the lift direction can be changed by adjusting the lower end of the propeller 5 to control the lift size and direction, so that the lift gradually increases, pushing the vehicle off the ground and starting to take off.
