Embodiment Construction
[0020] Such as figure 1 The vehicle shown has four wheels. The appearance is the same as that of a general electric wheelchair. The significant difference is that the wheels are smaller, and its central shaft protrudes outward. The top of the shaft is equipped with a folding paddle rotor. The diameter of the paddle when it is unfolded is Larger than the diameter of the wheel, but when folded down, keeps the rotor tip off the ground.
[0021] The folding paddle and the wheel are driven by the same motor, and its specific structure is detailed in Figure 4 Shown: among the figure 80 is the blade of the rotor, 83 is the gear tube, the gear tube is sleeved on the motor shaft 81 and can rotate freely, and can drive the wheel 84 to rotate with the hub of the wheel 84; the root of the blade 80 has The protruding tooth 801 , the centrifugal force is insufficient when the blade rotates at a low speed, and when it is pulled by the spring 82 to fold down, the protruding tooth 801 engag...

The invention provides a foldable flying wheel chair. The foldable flying wheel chair is a vehicle, which can be changed into a four-axis aircraft; the vehicle body is provided with two fixed leg boards capable of being turned over towards two sides; rotor wings and wheels are mounted on the leg boards; the rotating surfaces of the rotor wings and the rotating surfaces of the wheels are parallel; when the flying wheel chair runs on the ground, the two leg boards are turned over downwards and extremely until tires of the wheels are in contact with the ground; when the foldable flying wheel chair flies, the two leg boards are turned over to be flushed with the rotating surfaces of the rotor wings; each rotor wing and the wheel mounted on the same leg board are driven by the same motor; the motor runs at a low rotating speed in flying, springs arranged on the rotor wings enable blades to be folded downwards and convex teeth at the roots of the blades are meshed with gear pipes on rotor wing shafts so as to drive the wheels. The foldable flying wheel chair has the advantages that the foldable flying wheel chair is simple in structure and reliable, low in cost, wide in market covering surface and low in energy consumption, small, convenient, portable and easy to park, economic and environment-friendly.
Description
technical field [0001] This case concerns the field of road vehicles, in particular an amphibious vehicle that can be transformed into a quadcopter. Background technique [0002] Although today's small cars can run at over a hundred speeds per hour, the average speed is usually only 30 kilometers in stop-and-go traffic in congested urban areas. Therefore, the car is a means of transportation with high energy consumption and high cost. This case aims to design a small and convenient vehicle with low energy consumption that can be converted into a quadcopter to fly over roadblocks and congestion areas to improve traffic efficiency. [0003] Witold Mielniczek, a designer at Southampton University in the United Kingdom, has designed a vehicle that can be transformed into a quadcopter, and his work was showcased on Kickstarter at [0004] (https: / / www.kickstarter.com / projects / 2017062404 / b-go-beyond). [0005] The key point of the combination of the wheel and the rotor in the w...
