Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unmanned aircraft take-off / landing platform, and more particularly to an unmanned aircraft take-off / landing platform having a function of suppressing a ground effect generated on an unmanned aircraft and an unmanned aircraft landing surface during landing of the unmanned aircraft.

Describes the current situation regarding take-off and landing platforms of unmanned aerial vehicles (UAVs).
As unmanned aerial vehicles, mainly "small multi-copters that can be remotely controlled" are assumed.
In conventional unmanned aircraft take-off and landing platforms (also called heliports), it prevents the occurrence of ground effects, which is a phenomenon in which a circulating flow occurs between the unmanned aircraft and the surface of the take-off and landing platform of an unmanned aircraft when landing an unmanned aircraft. Therefore, a suction hole is provided on the board surface of the take-off and landing platform.

Japanese Patent Laid-Open No. 5-195515

By the way, as described above, in a conventional take-off and landing platform, for example, in the case of a helicopter, there is a case where a suction hole is provided on the board surface of the take-off and landing platform in order to prevent generation of a ground effect at the time of landing.
However, in the case of a conventional take-off / landing platform for an unmanned aerial vehicle, such a function for suppressing the ground effect is not provided.
For this reason, when landing an unmanned aerial vehicle on a conventional take-off / landing platform for an unmanned aerial vehicle, a ground effect occurs between the unmanned aerial vehicle and the take-off / landing platform for an unmanned aerial vehicle. There is an inconvenience.
Also, if the unmanned aerial vehicle becomes unstable due to the occurrence of a ground effect during landing, it is necessary to pay close attention to the landing operation of the unmanned aircraft, and the unmanned aircraft may break down due to the landing failure. There is an inconvenience.

  As a take-off / landing platform for unmanned aerial vehicles, it is possible to use a net-like or mesh-like platform, but since the upper and lower surfaces of the take-off / landing platform are always in communication, the occurrence of ground effects during landing will occur. However, at the time of takeoff, the lift due to the ground effect cannot be used, and improvement has been desired.

  In addition, there may be a plan to land an unmanned aerial vehicle directly on the ground without using a take-off and landing platform, but when the unmanned aircraft lands, dust and dust on the ground rise, There is an inconvenience of being easily damaged.

Furthermore, because of the situation of the above-mentioned unmanned aircraft take-off and landing platform, there is a pilot who does not use the take-off and landing platform at the time of landing, but keeps the unmanned aircraft in a low altitude state and grabs the unmanned aircraft.
However, it is not easy for beginners to operate the aircraft with one hand while grabbing the unmanned aircraft with the other hand, and even an experienced pilot can grasp the unmanned aircraft while operating the unmanned aircraft in a strong wind. It is difficult to take.
In addition, the method of grabbing the unmanned aerial vehicle at the time of landing has the disadvantage that it cannot be applied when landing at a remote location.

  An object of the present invention is to facilitate landing operation of an unmanned aerial vehicle by providing a ground effect reducing means for reducing a ground effect generated at the time of landing of the unmanned aircraft on a board surface of a takeoff / landing platform of the unmanned aircraft.

Therefore, in order to eliminate the inconvenience described above, the present invention provides an unmanned aircraft take-off / landing platform having an unmanned aircraft take-off / landing surface on the upper surface, and the surface of the take-off / landing platform has a ground effect upon landing of the unmanned aircraft. A ground effect reducing means for reducing the ground effect is provided , and when the through hole portion communicating with the upper surface and the lower surface is formed on the board surface of the take-off and landing platform, the ground effect reducing means switches the communication state of the through hole portion. And an air suction portion that actively reduces the ground effect by flowing air on the upper surface side of the panel surface to the lower surface side when the through hole portion is in communication .

According to the present invention, in the unmanned aircraft take-off / landing base having an unmanned aircraft take-off / landing surface on the upper surface, the ground effect reducing means for reducing the ground effect during landing of the unmanned aircraft is provided on the surface of the take-off / landing base. Therefore, it is possible to reduce the ground effect that occurs when landing an unmanned aerial vehicle, so that the unmanned aircraft does not become unstable when landing, and the landing operation of the unmanned aircraft can be facilitated. It becomes.
In addition, by using the unmanned aircraft takeoff and landing platform, the unmanned aircraft does not land directly on the ground, and it is difficult for the dust and dust on the ground to soar because there is a gap from the ground when the unmanned aircraft lands, It is possible to prevent the unmanned aircraft from being damaged by dust or dust.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 to 3 show Embodiment 1 of the present invention.
1 to 3, reference numeral 1 denotes an unmanned aircraft take-off and landing platform, and 2 denotes an unmanned aircraft.
The take-off and landing platform 1 of the unmanned aircraft 2 is configured in a table shape by a rectangular board surface 3 on which the unmanned airplane 2 can take off and landing, and four legs 4 that support the board surface 3.
At this time, the board surface 3 serves as a ground effect reducing means for reducing the ground effect at the time of landing of the unmanned aerial vehicle 2, and at least one through hole portion 5 communicating with the upper surface and the lower surface, and the through hole portion 5. And an open / close switching unit 6 that increases or decreases the ground effect by switching the communication state.
The through-hole portion 5 may have a quadrangular shape, a circular shape, or other shapes. In the first embodiment, as shown in FIGS. Are formed in a plurality of groove shapes.
The opening / closing switching portion 6 is composed of a plate-like member 7 having a size capable of closing the groove-shaped through-hole portion 5, and a shaft member 8 is formed at one end of the plate-like member 7. An urging means 9 made of a spring or the like that keeps the shaft member 8 open at all times (see FIG. 3) is disposed.
In addition, regarding the arrangement of the urging means 9, it is possible to adopt a configuration in which the urging means 9 is arranged and interlocked only at one place, but in the first embodiment, it will be described as a configuration in which each of the shaft members 8 is arranged. .
Further, an opening string 10 is attached to the other end of the plate-like member 7, and a string fixing tool 11 for temporarily fixing the movement of the opening string 10 is provided at an intermediate portion of the opening string 10.

  Next, the operation of the first embodiment will be described.

The configuration disclosed in the first embodiment of the present invention assists the take-off and landing of the unmanned aircraft 2.
That is, when the unmanned aircraft 2 takes off from the takeoff / landing platform 1, the opening / closing switching unit 6 is opened against the urging force of the urging means 9 while pushing the string fixing tool 11 of the opening / closing switching unit 6. By pulling the cord 10, the plate-like member 7 is rotated around the shaft member 8 in the direction of closing the through-hole portion 5, and the plate-like member 7 closes the through-hole portion 5.
Thereafter, the movement of the opening string 10 is temporarily fixed by releasing the force that pushes the string fixing tool 11 of the opening / closing switching unit 6, and the state in which the through hole 5 is blocked by the plate-like member 7 is temporarily. Maintained.
And, when the unmanned aerial vehicle 2 takes off, the plate-like member 7 closes the through-hole portion 5, so that lift (ground effect) is generated between the unmanned aircraft 2 and the surface 3 of the unmanned aircraft 2, and quick takeoff is possible. Become.
When landing the unmanned aerial vehicle 2 on the takeoff / landing platform 1, the string 10 for opening can be slid freely by pushing the string fixing tool 11 of the opening / closing switching unit 6.
Here, when the opening string 10 becomes slidable, the plate-like member 7 that has blocked the through-hole portion 5 is rotated about the shaft member 8 by the urging force of the urging means 9, and the through-hole portion 5 Becomes a through state.
For this reason, when the unmanned aircraft 2 is landed, the air flow generated from the unmanned aircraft 2 toward the board surface 3 is removed from the through-hole portion 5 so that the ground effect on the unmanned aircraft 2 is suppressed, and the unmanned aircraft 2 is pushed up. This makes it possible to land stably.

Thus, in the take-off and landing platform 1 of the unmanned aircraft 2 having the surface 3 on which the unmanned aircraft 2 can take off and land, the ground effect at the time of landing of the unmanned aircraft 2 is reduced on the surface 3 of the take-off and landing platform 1. The ground effect reducing means is provided.
Accordingly, when the unmanned aerial vehicle 2 is landed, the ground effect generated between the unmanned aerial vehicle 2 and the board surface 3 can be reduced, thereby enabling a stable landing and the unmanned aerial vehicle 2 due to a landing failure. It is possible to reduce the possibility of malfunctioning.
Further, the ground effect reducing means switches the communication state of the through-hole portion 5 to reduce the ground effect when the through-hole portion 5 communicating with the upper surface and the lower surface is formed on the board surface 3 of the take-off and landing platform 1. The plate-like member 7 that closes the through-hole portion 5 of the opening / closing switching portion 6 is provided.
Therefore, when the unmanned aircraft 2 is landed, the ground effect is reduced by the through-hole portion 5 as described above, and the unmanned aircraft 2 is closed by taking up the through-hole portion 5 during take-off while assisting safe landing. By generating a ground effect between the board surfaces 3, the propulsive force to the unmanned aerial vehicle 2 is increased, and quick takeoff is possible.
Further, in the first embodiment, an urging means 9 is provided for always opening the shaft member 8 of the plate-like member 7.
Therefore, the shaft member 8 of the plate-like member 7 can be always opened by the biasing force of the biasing means 9, and the ground effect during landing of the unmanned aircraft 2 is reliably reduced by the through-hole portion 5. It is possible to make it.
Furthermore, since the take-off / landing platform 1 of the unmanned aircraft 2 is used, the unmanned aircraft 2 is not directly landed on the ground.
Accordingly, since there is a space from the ground when the unmanned aerial vehicle 2 is landed, it is difficult for the dust and dust on the ground to rise, and the unmanned aircraft 2 can be prevented from being damaged by the dust and dust.

  4 to 6 show Embodiment 2 of the present invention.

  The feature of the second embodiment is that the opening / closing switching unit 26 described later is a slidable opening / closing switching panel surface 27, while the air on the upper surface side of the panel surface 23 is allowed to flow to the lower surface side to actively reduce the ground effect. The air suction unit 29 is provided.

4 to 6, reference numeral 21 denotes a take-off / landing platform for the unmanned aerial vehicle 2, and 2 denotes an unmanned aerial vehicle.
The takeoff and landing platform 21 of the unmanned aircraft 2 includes a board surface 23 and a foot 24.
The panel surface 23 includes a through-hole portion 25 and an opening / closing switching portion 26.
The opening / closing switching unit 26 includes an opening / closing switching panel surface 27 having a hole at the same position as the through-hole portion 25 of the panel surface 23, and the opening / closing switching panel surface 27 is slidably attached to a lower portion of the panel surface 23. .
The open / close switching board surface 27 is provided with a moving lever 28 for sliding the open / close switching board surface 27.
Further, an air suction part 29 comprising a fan is attached to the opening / closing switching board surface 27 of the opening / closing switching part 26 so that the air suction part activation switch 30 can be switched between starting and stopping in conjunction with the sliding movement of the opening / closing switching board surface 27. Configure.

  Next, the operation of the second embodiment will be described.

When the unmanned aircraft 2 takes off from the takeoff / landing platform 21, the open / close switching panel 27 is slid by pulling the moving lever 28 of the open / close switching unit 26 to block the through hole 25.
At this time, when the open / close switching board surface 27 closes the through-hole portion 25, when the unmanned aircraft 2 takes off, a lift (ground effect) is generated between the unmanned aircraft 2 and the board surface 23, and quick takeoff is possible. .
Further, when the unmanned aircraft 2 is landed on the takeoff / landing platform 21, by pushing the moving lever 28 of the opening / closing switching unit 26, the through hole 25 provided in the panel surface 23 and the opening / closing switching panel surface of the opening / closing switching unit 26. 27 is overlapped with the hole provided in 27, and the through hole 25 is in a through state.
Further, when the moving lever 28 is pushed in, the open / close switching panel surface 27 slides, the air suction unit activation switch 30 is turned on, and when activated, the air suction unit 29 is activated, and the air suction unit 29 is moved to the surface 23 of the panel 23. The ground effect is actively reduced by flowing the air on the upper surface side to the lower surface side.
For this reason, when the unmanned aerial vehicle 2 is landed, the air flow generated from the unmanned aerial vehicle 2 toward the board surface 23 is removed from the through hole 25, so that the ground effect on the unmanned aerial vehicle 2 is suppressed and the unmanned aircraft 2 is pushed up. This reduces the amount of damage and enables stable landing.

Thereby, in the takeoff / landing base 21 of the unmanned aircraft having the surface 13 on which the unmanned aircraft can take off / land, the ground effect reducing means for reducing the ground effect at the time of landing of the unmanned aircraft 2 is provided on the surface 23 of the takeoff / landing base 21. It is set as the structure which provided.
Therefore, when the unmanned aerial vehicle 2 is landed, the ground effect generated between the unmanned aerial vehicle 2 and the board surface 23 can be reduced. As in the first embodiment, this enables a stable landing. Thus, it is possible to reduce the possibility of causing the unmanned aircraft 2 to fail due to the landing failure.
Therefore, when the unmanned aerial vehicle 2 is landed, the ground effect generated between the unmanned aerial vehicle 2 and the board surface 23 can be reduced, thereby enabling stable landing.
In addition, since stable landing can be performed, it is possible to reduce the possibility that the unmanned aircraft 2 is erroneously operated and malfunctioned when landing fails.
Further, the ground effect reducing means opens and closes to reduce the ground effect by switching the communication state of the through-hole portion 25 when the through-hole portion 25 communicating with the upper surface and the lower surface is formed on the surface of the take-off and landing base 21. The switching unit 26 includes an open / close switching panel surface 27.
Therefore, when the unmanned aerial vehicle 2 is landed, the ground effect is reduced and the safe landing is assisted as described above, and at the time of takeoff, the through hole 25 is closed by the open / close switching panel 27 of the open / close switching unit 26. The unmanned aerial vehicle 2 is caused to have a ground effect between the board surfaces 23, the propulsive force to the unmanned aerial vehicle 2 is increased, and a quick takeoff is possible.
Furthermore, the ground effect reducing means switches the communication state of the through-hole portion 25 and reduces the ground effect when the through-hole portion 25 communicating with the upper surface and the lower surface is formed on the surface 23 of the take-off and landing base 21. While the open / close switching unit 26 is provided, the air suction unit 29 is configured to actively reduce the ground effect by flowing air on the upper surface side of the panel surface 23 toward the lower surface side when the through-hole portion 25 is in communication.
Therefore, the ground effect generated when the unmanned aircraft 2 is landing can be further reduced, and the stable landing of the unmanned aircraft 2 is possible.
Further, since the take-off / landing platform 21 of the unmanned aircraft 2 is used, the unmanned aircraft 2 is not directly landed on the ground.
Accordingly, since there is a space from the ground when the unmanned aerial vehicle 2 is landed, it is difficult for the dust and dust on the ground to rise, and the unmanned aircraft 2 can be prevented from being damaged by the dust and dust.

  The present invention is not limited to the first and second embodiments described above, and various application modifications can be made.

For example, in the first and second embodiments of the present invention, the switching of the communication state of the through-hole portion has been described as a manual configuration. However, the communication state is automatically switched by a drive motor, wireless, or wired. A configuration is also possible.
Then, the communication state can be switched by remote operation, and landing of an unmanned aircraft at a remote point can be facilitated.

  Further, in the first embodiment of the present invention, the configuration in which only the through-hole portion is formed on the board surface has been described. However, a net or a shock absorbing material is attached on the board surface to prevent damage or breakage during landing of the unmanned aircraft. It is also possible to have a special configuration to prevent.

Furthermore, in the second embodiment of the present invention, the open / close switching panel surface of the open / close switching unit having the same shape hole portion at the same position as the through hole portion of the panel surface is provided. It is also possible to adopt a method of changing the hole diameter.
In other words, the hole diameter of the open / close switching board surface is gradually increased with respect to the through hole part of the board surface, and a special configuration that increases the effect of either taking off or landing of the unmanned aircraft can be adopted.
Moreover, it is also possible to adopt a special configuration in which the hole effect of the open / close switching panel surface is directed outward with respect to the through hole portion of the panel surface to further expect the ground effect during landing of the unmanned aircraft.

Furthermore, in the second embodiment of the present invention, an open / close switching board surface that is slidable with respect to the board surface of the unmanned aerial vehicle is provided. However, it can be rotated around the center position of the board surface. A special configuration in which an open / close switching panel surface is provided is also possible.
In other words, this can be dealt with by forming through holes on the board surface and holes on the open / close switching board surface radially from the center position of the board surface.

In the first and second embodiments of the present invention, the board surface of the take-off and landing platform of the unmanned aerial vehicle has been described as a configuration made of a plate-like member. However, a special foldable configuration can be used to facilitate transportation.
If the foot of the take-off and landing platform of the unmanned aircraft can be adjusted, the board surface of the take-off and landing platform can be maintained almost horizontal even when there is unevenness on the ground, contributing to improved usability. Can do.
