Detailed Description of the Preferred Embodiment
Referring now to FIG. 1, it shows that a base 3 of the wing stand of the present invention is installed on a car 1 by means of four supporting rods 2. The supporting rods 2 may be made of steel or other suitable material for supporting the base 3 on the car 1. Among the supporting rods, a hollow tube may be arranged between the base 3 and the car. A plurality of electric wires (not shown) for controlling the operation of the wing stand or oil tubes for providing hydraulic pressure power to the wing stand can pass from the car body 1 to the base 3 through the hollow tube.
The base 3 includes a mass center adjusting mechanism for automatically or manually adjusting the mass center of the car during flying. The mass center adjusting mechanism includes a leftward/rightward mass center adjusting mechanism and a forward/rearward mass center adjusting mechanism thereon, which will be described in detail below.
The leftward/rightward mass center adjusting mechanism of the mass center adjusting mechanism is composed of two hollow tubes 41, two guide rods 42, two linkage rods 43, a driving rod 44, and a hydraulic actuator 45. The driving rod 44 is fixed between two hollow tubes 41. The two linkage rods 43 are firmly mounted between two hollow tubes 41. The hydraulic actuator 45 is capable of moving the hollow tubes 41 via the driving rod 44 along the guide rods 42.
When the mass center of the wing stand mounted on the base 3 is deviated in the leftward or rightward orientations, the leftward/rightward mass center adjusting mechanism can be controlled by a control device (not shown) within the car to get a balance in leftward or rightward direction. That is, if the car is inclined leftward due to an unbalance between the left side and right side of the car body, the mass center of the car and the wing stand will be deviated to the left side. At this time, the actuator 45 is capable of controlling the leftward/rightward mass center adjusting mechanism to move rightward so as to balance the mass center of the car. Similarly, if the car is inclined rightward, the mass center of the car will be deviated to the right side. At this time, the actuator 45 is capable of controlling the leftward/rightward mass center adjusting mechanism to move leftward so as to balance the mass center of the car.
The forward/rearward mass center adjusting mechanism of the mass center adjusting mechanism of the present invention is composed of two hollow tubes 51, two linkage rods 52, a driving rod 53, and a hydraulic actuator 54. The driving rod 53 is fixed between the two hollow tubes 51. The two linkage rods 52 are fixed between two hollow tubes 51. The hydraulic actuator 54 is capable of moving the hollow tubes 51 via the driving rod 53 along the linkage rods 43 of the leftward/rightward mass center adjusting mechanism described above.
When the mass center of the car and the wing stand mounted on the base 3 is deviated in the forward or rearward orientations, the forward/rearward mass center adjusting mechanism can be controlled by a control device (not shown) within the car to get a forward/rearward balance. That is, if the car is inclined forward due to an unbalance between the front end and rear end of the car body, the mass center of the car and the wing stand will be deviated to the forward direction. At this time, the actuator 54 is capable of controlling the forward/rearward mass center adjusting mechanism to move rearward so as to balance the mass center of the car. Similarly, if the car is inclined rearward, the mass center of the car will be deviated to the rearward direction. At this time, the actuator 54 is capable of controlling the forward/rearward mass center adjusting mechanism to move forward so as to balance the mass center of the car.
Referring to FIG. 3, a perspective view showing a wing stand is mounted on the base 3 of the present invention is shown. The wing stand includes a frame 6 mounted on the leftward/rightward mass center adjusting mechanism and the forward/rearward mass center adjusting mechanism. So, the position relative to the base of the wing stand may be moved by the leftward/rightward mass center adjusting mechanism and the forward/rearward mass center adjusting mechanism. Four propellers 71 are arranged at corners of the frame 6. Preferably, the front two propellers are mounted on a front frame 61 of the frame 6, the inclined angle of which may be changed by front hydraulic actuators. Similarly, the rear two propellers are mounted on a rear frame 62 of the frame 6, the inclined angle of which may be changed by rear hydraulic actuators. So, the inclined angle of the propellers 71 is controllable by the driver if desired by actuating the hydraulic actuators 71a.
In operation, each of the propellers 12 is first actuated by the hydraulic actuators 71a at a vertical angle (as shown in FIG. 3) and then rotates rapidly. This will cause the air above the car body to flow more rapidly than that below the car body, thus an upward dynamic lift force will act on to the car body. So, the car may be lifted upward to a desired height.
At this time, the angle of the propellers 71 may be changed by the hydraulic actuators 71a, as shown in FIGS. 4 and 5, and finally to a horizontal direction, as shown in FIG. 6. At this time, the air in front of the car body will flow more rapid than that behind the car body. So, a forward dynamic force is induced to the car body, so that the car may fly forward. During the flying operation described above, the mass center of the car is adjusted by the leftward/rightward mass center adjusting mechanism and the forward/rearward mass center adjusting mechanism.
With reference to FIG. 7, there is shown a tail helm 9 is installed on the rear portion between two rear propellers of the wing stand. The function of the tail helm 9 is used to change the flying orientation of the car during flying.
As shown in FIG. 8, a perspective view of the present invention is shown, showing the wing stand mounted on the base of the present invention is folded upward and inward, which can reduce the width of the wing stand when the car is driven on the road.
Preferably, as shown in FIG. 9, the wing stand of the present invention may further includes an emergency parachute 81 for emergency purpose. The emergency parachute 81 may be contained in a container 8 provided on the wing stand 6, and it may be used by the driver in emergency.
Although the preferred embodiments of the present invention have been described to illustrate the present invention, it is apparent that changes and modifications in the specifically described embodiments can be carried out without departing from the scope of the invention which is intended to be limited only by the appended claims.
