Description

Technical Field

[0001] The invention belongs to the field of flying cars and relates to a foldable dual-mode flying car. Background Art

[0002] With the rapid development of science and technology and the progress of human society, transportation methods are also constantly innovating and optimizing. In recent years, with the acceleration of urbanization and the improvement of residents' living standards, the traditional ground transportation system has become increasingly saturated, and problems such as traffic congestion, air pollution, and energy consumption have become increasingly prominent. In order to alleviate these problems and improve travel efficiency, flying cars, as a new type of transportation, have gradually attracted attention and research from all walks of life.

[0003] Flying cars, that is, vehicles that can travel on the ground and have flying functions, provide an efficient and convenient transportation solution by combining the advantages of cars and aircraft. At present, many companies and research institutions are developing flying cars, such as Tesla, Uber and Airbus. These companies use electric vertical take-off and landing (eVTOL) technology, hybrid power systems, advanced materials and autonomous driving technology to gradually move flying cars from the conceptual stage to practical application.

[0004] Despite this, flying cars still face many challenges, such as the inconvenience of fixed wings due to their length, the limited flight time due to the high consumption of vertical flight, etc. In addition, the popularization of flying cars also needs to consider many aspects such as airspace management, traffic regulations, and infrastructure construction. Although some prototypes of existing flight technology have been tested, they still need to be further optimized and broken through in terms of convenience, range, and intelligent control.

[0005] In summary, the problems with the existing technology are: the fixed wings of the flying car are large in size. Even though the SD-03 is currently the smallest vertical take-off and landing vehicle in the world, it still needs to occupy two parking spaces. The flying car needs to consume a lot of energy to overcome gravity when taking off. When flying, it will be subject to greater air resistance, which increases its energy consumption. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention aims to provide a foldable dual-mode flying car. The flying car has a foldable propeller and a self-tilting folding wing mechanical structure, which solves the problem of the large size of the fixed wings of the low-altitude aircraft flying car. The flying car can take off, land and dock in a smaller space and with higher efficiency, thereby ensuring space utilization.

[0007] The present invention is achieved through the following technical solutions.

[0008] A foldable dual-mode flying car comprises a flying car body, wheels, and a flying car tilting wing, wherein the wheels and the flying car tilting wing are arranged on the flying car body;

[0009] The tilting wing of the flying car comprises a tilting wing main body mechanism, a tilting rod main body mechanism, a folding blade mechanism, and a coaxial double-propeller power mechanism. The tilting wing main body mechanism is connected to the tilting rod main body mechanism, the folding blade mechanism is assembled on the coaxial double-propeller power mechanism, the coaxial double-propeller power mechanism is connected to the tilting main body mechanism, the tilting main body mechanism passes through the flying car body and can rotate around the flying car body, the tilting main body mechanism connects the wing main body mechanism and the coaxial double-propeller power mechanism, the wing main body mechanism is located on the inner side, and the coaxial double-propeller power mechanism is located on the outer side; the wing main body mechanism is transformed from a vertical placement to a horizontal placement after the flying car is started, and the air velocity difference between the upper and lower ends generated during the movement of the flying car is used to provide lift for the flying car, and the folding blade mechanism rotates under the power provided by the coaxial double-propeller power mechanism to provide upward lift for the flying car.

[0010] Further, the tilt-wing main body mechanism includes a telescopic stepping motor, a support plate, a steering gear rod, a steering gear motor, a rear half of the wing, a fixing plate 1, a slider, a fixing plate 2, a tilt axis, and a front half of the wing;

[0011] Taking the right front tilt wing of the flying car as an example (the left front tilt wing of the car is symmetrical with the right front tilt wing structure, the right rear tilt wing of the car is the same as the right front tilt wing of the car, and the right front tilt wing of the car is symmetrical with the right rear tilt wing of the car), the telescopic stepper motor is connected and fixed to the support plate by means of screws, and the support plate is fitted together with the rear half of the wing, and the steering gear rod is fixed to the steering gear motor by means of a latch structure and screws, and the telescopic stepper motor can pull the movement of the support plate through its own telescopic movement, so that it can cover the steering gear motor when the flying car is flying, the steering gear rod is connected to the rear half of the wing and the steering gear motor, thereby fixing one side of the steering gear motor to the rear half of the wing, and the tilt shaft is connected to the front half of the wing and the steering gear motor, thereby fixing the other end of the steering gear motor to the front half of the wing, and the steering gear motor can rotate under the control of the driver, thereby driving the front half of the wing to rotate;

[0012] The slider is connected to the rear half of the wing by means of a T-shaped structure and can slide. At the same time, the slider is connected to one end of the fixing plate one by means of a latch structure, and the other end of the fixing plate one is connected to the fixing plate two by means of a latch structure. The fixing plate two is a protruding part on the outer side of the front half of the wing. The fixing plate one is connected to the front half of the wing by means of the fixing plate two, and the other end of the fixing plate one is connected to the slider. The slider is connected to the rear half of the wing by means of the T-shaped structure, and can move along with the rotation of the steering gear motor when the steering gear motor rotates, and can also provide support for the front half of the wing and the rear half of the wing.

[0013] Further, the main mechanism of the tilting rod includes a supporting cylinder, a fixing ring 1, a gearbox, a load-bearing ring, a fixing ring 2, a cylindrical roller bearing 1, a sleeve, a cylindrical roller bearing 2, a gasket 1, a gasket 2, a nut, a fixing ring 3, a tilting rod, a reinforcement support device, a bearing column, a roller bearing, and a retaining spring;

[0014] The support cylinder is connected to the gearbox by means of a fixing ring 1, and the load-bearing ring fixes the gearbox on the support cylinder by means of bolts and nuts. The fixing ring 2 fixes the gearbox on the tilt rod by means of bolts and nuts. The inner ring of the sleeve passes through the tilt rod, and a cylindrical roller bearing 2 is sleeved on the tilt rod on the left side of the sleeve, and a gasket 1 is sleeved on the left side of the cylindrical roller bearing 2. At the same time, a fixing ring 3 is fixed to the tilt rod tightly against the gasket 1 by means of a nut. A cylindrical roller bearing 1 is sleeved on the tilt rod on the right side of the sleeve, and a gasket 2 is sleeved on the right side of the cylindrical roller bearing 1. At the same time, the fixing ring 2 is relied on to prevent the sleeve from sliding left and right. The bearing column, roller bearing, and retaining spring are coaxially sleeved on the tilt rod from right to left in sequence, and the reinforcement support device is sleeved on the outside of the bearing column, roller bearing, and retaining spring to fix them on the tilt rod. This assembly method can assemble a tilt rod body, which can drive the wing part of the flying car to tilt, and the tilt angle can be any degree, which greatly improves the tilt angle and degree of freedom of the general tilt wing.

[0015] Furthermore, the folding blade main body mechanism includes the upper half of the lower rotor folding blade, the lower half of the lower rotor folding blade, the upper half of the upper rotor folding blade, the lower half of the upper rotor folding blade, a fixing screw, and a folding blade motor. The combined structure of the upper and lower rotor folding blades is the same. Taking the upper rotor as an example (the structure of the lower rotor is the same as that of the upper rotor), the three parts of the section of the upper half of the upper rotor folding blade are beveled at two different angles, and a guide rail and a space for placing the folding blade motor are opened in the middle of the section. A fixing screw is placed on the upper surface to fix it to the folding blade motor. A cylindrical transmission shaft at one end of the motor is connected to the lower half of the upper rotor folding blade. After the folding blade motor is started with the help of electric energy, it drives the cylindrical transmission shaft hidden in the folding blade of the lower rotor, driving the blade to rotate downward along the axis where it is located, thereby completing the folding action of the blade. Such a hidden structure not only ensures that the aerodynamic design does not increase additional air resistance, but also has both space utilization and aesthetic design. Driven by a folding blade motor, the power is directly provided to the transmission shaft and acts directly on the blades, reducing the complexity and energy loss of the transmission chain. At the same time, the force is uniform and stable, which greatly improves the driving efficiency and stability.

[0016] Further, the coaxial double-propeller power mechanism includes a transmission sleeve 1, a transmission sleeve 2, a driving gear, a transmission gear, a blade motor, a ball bearing 1, a ball bearing 2, a ball bearing 3, a cylindrical bearing 1, and a cylindrical bearing 2. The ball bearing is coaxially sleeved on the blade motor, the transmission sleeve is coaxially sleeved on the blade motor, the transmission sleeve 2 is coaxially sleeved on the blade motor, the driving gear is coaxially sleeved on the blade motor, and the ball bearing 1, the transmission sleeve 1, the transmission sleeve 2 and the driving gear are coaxially sleeved from top to bottom; the cylindrical bearing is coaxially sleeved between the blade motor and the upper part of the transmission sleeve 1; the ball bearing 2 is coaxially sleeved between the transmission sleeve 2 and the blade motor; the cylindrical bearing 2 is coaxially sleeved on the blade motor, and its position along the axis is located between the transmission sleeve and the transmission sleeve 2; The pinion of the transmission gear is meshed with the gear at the lower end of the transmission shaft sleeve, the large gear of the transmission gear is meshed with the driving gear, and the central axes of the two transmission gears are on the same axis; the two ball bearings three are respectively coaxially sleeved on the central pin of the transmission gear, and the two ball bearings three are close to the two large gear sleeves of the transmission gear in the axial direction. After the blade motor is started with the help of electric energy, it will drive the driving gear to rotate together, and when the driving gear rotates, it will drive the two transmission gears to rotate. Since the two transmission gears are meshed with the transmission shaft sleeve 1 and the transmission shaft sleeve 2 by means of gears, the transmission gear can transfer the rotational kinetic energy to the transmission shaft sleeve 1 and the transmission shaft sleeve 2, thereby driving the two components to rotate, thereby driving the folding blades at the upper ends of the transmission shaft sleeve 1 and the transmission shaft sleeve 2 to rotate to provide lift for the flying car.

[0017] Furthermore, the wheels are foldable wheels.

[0018] Furthermore, it also includes a solar panel mechanism, which is arranged on the top of the flying car body. The solar panel mechanism converts solar energy into electrical energy to supply power to the tilt-wing part of the flying car.

[0019] Compared with the prior art, the advantages of the present invention are as follows: the present invention has a foldable propeller and a self-tilting folding wing mechanical structure, which solves the problem of the large size of the fixed wings of the low-altitude aircraft flying car, and can complete the take-off, landing and docking of the flying car in a smaller space and with higher efficiency, thereby ensuring space utilization.
