<Details of the embodiment>
Hereinafter, a flying object and a flying object control method according to an embodiment of the present invention will be described with reference to the drawings.

In the following description, terms may be used according to the following definitions.
Front / rear direction: + X direction and X direction Up / down direction (or vertical direction): + Z direction and Z direction Left / right direction (or horizontal direction): + Y direction and Y direction Traveling direction (front): + X direction Backward direction (rear): -X Direction Up direction (upward): + Z direction Downward direction (downward): -Z direction

<Configuration of the flying object>
The flying object described below generally has the following configuration.

<Control unit>
It has a flight controller and sensors, observes / estimates the flight state, and calculates a command to be sent to the power unit in order to realize a desired operation.

  The flight controller can include a programmable processor (eg, a central processing unit (CPU)) and the like, and can include a logic code executable by the flight controller and a memory for storing program instructions. good.

  The memory may include, for example, a detachable medium such as an SD card or an external storage device. Data obtained from cameras and sensors may be transmitted directly to the memory and stored. For example, still image / moving image data shot by a camera or the like is recorded in a built-in storage device or an external storage device.

  Sensors in the control unit may include inertial sensors (acceleration sensors, gyro sensors, etc.), GPS sensors, proximity sensors (eg, LIDAR), or vision sensors (eg, cameras).

<Power section>
A thrust generator and a thrust controller such as a motor, an ESC (Electronic Speed Controller), and a propeller are provided, and a desired flight is realized by receiving signals from a flight controller and a transceiver. The thrust generator may use a gasoline engine or the like in addition to the electric motor.

  In the propeller of the present invention, the blade has an elongated shape. There may be any number of blades (rotors) (eg, 1, 2, 3, 4, or more blades). Further, the shape of the blade can be any shape such as a flat shape, a bent shape, a twisted shape, a tapered shape, or a combination thereof.

  In addition, the shape of a blade | wing can change (for example, expansion / contraction, folding, bending, etc.). The vanes may be symmetrical (having the same upper and lower surfaces) or asymmetric (having differently shaped upper and lower surfaces).

  The vanes can be formed into a suitable geometry to generate dynamic aerodynamic forces (eg, lift, thrust) as the vanes are moved through the air, wings, or air. The blade geometry can be selected as appropriate to optimize the dynamic air characteristics of the blade, such as increasing lift and thrust and reducing drag.

  The motor causes the rotation of the propeller. For example, the drive unit can include an electric motor or an engine. The vanes can be driven by a motor and rotate around a rotation axis of the motor (eg, the long axis of the motor) in a clockwise and / or counterclockwise direction.

  All the blades can rotate in the same direction, or can rotate independently. Some of the blades rotate in one direction and the other blades rotate in the other direction. All of the blades can be rotated at the same rotational speed, and can be rotated at different rotational speeds. The number of rotations can be determined automatically or manually based on the dimensions (for example, size, weight) of the moving body and the control state (speed, moving direction, etc.).

  The flying object has an arm (frame) that supports a corresponding motor and propeller. The arm may be provided with a coloring body such as an LED to indicate the flight state, flight direction, etc. of the flying body. The arm according to the present embodiment can be formed of a material appropriately selected from carbon, stainless steel, aluminum, magnesium, etc., or alloys or combinations thereof.

  The flying body may include a mounting portion as necessary. The mounting unit is a mechanism for mounting and holding a mounting object (camera, luggage L holding unit, work tool, etc.). The mounting unit may be configured to always hold the state in a predetermined direction (for example, the horizontal direction (vertically downward)) so that the mounting object position and orientation can be maintained.

  The mounting portion may be connected to the arm via a connection portion (gimbal: a connection portion that can be displaced within a predetermined range). In this case, the mounting object is configured to bend according to the inclination of the flying object, with the connecting portion as a fulcrum. According to such a configuration, the arm portion and the mounting portion of the flying object are connected via the connection portion so as to be independently displaceable. The angle of displacement is not particularly limited. For example, even when the flying object flies in a forward leaning posture, it is only necessary to keep the position and direction of the mounted object horizontal. As a result, the mounted object is always held in a state of being suspended vertically downward, and can be delivered to the destination while maintaining the position and state at the departure point.

  The connecting portion according to the present embodiment is movable (uniaxial gimbal) only in the front-rear direction, which is the same direction as the traveling direction. However, it may also be movable in the left-right direction (biaxial gimbal).

  The connecting portion may be controlled by a motor or the like. Thereby, the wobbling (natural vibration or the like) of the mounted object is further prevented during the flight.

  The shape / mechanism of the mounting portion is not particularly limited as long as it can store and hold the mounting target, and any method can be used as long as the mounting target can tilt or hold its position. It may be anything. In addition, on the mounting part, sensors for obtaining visual information such as cameras, various sensors for detecting the standby state such as wind power, information transmission devices such as speakers and monitors, gripping and cutting objects, etc. There may be provided a working unit for performing the above.

<Transmitter / receiver>
Arbitrary communication means such as wired communication or wireless communication is provided with other flying objects and pilots, and arbitrary information can be transmitted to and received from the control unit and power unit.

<Power source>
Provide an energy source such as a battery. You may provide not only electrical energy but chemical energy, such as gasoline, and an energy conversion module. Further, for example, a power storage module by non-contact power feeding such as wireless power transmission may be provided.

<Other sensors and operating parts>
There may be a sensor and an operation mechanism provided for the purpose of not taking part directly in realizing the flight such as aerial photography or radio wave relay. For example, there are a camera sensor, a temperature sensor, a gimbal mechanism, a property dropping mechanism, and the like.

  The configuration described above can be adopted in all or part of the embodiments described below. In addition, since the present application includes many embodiments, the same reference numerals may be assigned to different configurations in different embodiments. In this case, refer to each embodiment and each drawing referred to in the embodiment. Moreover, as long as the purpose does not contradict each embodiment, it is possible to combine some elements as appropriate.

(First embodiment)
As shown in FIGS. 2 to 4, the arm portion and the loading portion of the flying body according to the present embodiment are configured to be independently displaceable at least in the horizontal direction and the vertical direction. More specifically, as shown in FIG. 4, the flying body includes a plurality of (for example, four) rotor blades, a flight unit including a motor that rotates the rotor blades, and a frame that supports the motor, and the flight. And a mounting part located at the center of the part. The frame includes a portion having a rectangular shape in the center and an enclosed space inside. The mounting portion exists at least partially in the enclosed space. The frame and the mounting portion are connected by a gimbal and a gimbal that can be displaced in the pitch direction and the roll direction (more precisely, a partial rotational displacement). The mounting part has a rail part which can move a load.

  As shown in FIG. 2, a method of moving the load L mounted on the mounting portion between the first flying body (lower flying body) and the second flying body (upper flying body) is as follows. Done. First, the first flying object is positioned below the second flying object.

  At this time, the relative positions (velocities) of the first flying object and the second flying object are locked. As a locking method, a physical method may be used, or the positions of each other may be locked by software. In the figure, since the cargo L is being delivered while proceeding in the left direction, the flying portion is shown tilted, but in the stationary state, the flying portion is parallel to the horizontal direction.

  Subsequently, the load L in the loading unit of the first flying object is pulled up to the loading unit of the second flying object (see FIG. 2). Thereby, the movement of the luggage L from the first flying object to the second flying object is completed.

(Other moving methods of this embodiment)
Another moving method according to the present embodiment is performed as follows. First, the first flying object is located above the second flying object (not shown).

  At this time, the relative positions (velocities) of the first flying object and the second flying object are locked. As a locking method, a physical method may be used, or the positions of each other may be locked by software.

  Subsequently, the load L in the loading unit of the first flying object is pulled down to the loading unit of the second flying object. Thereby, the movement of the luggage L from the first flying object to the second flying object is completed.

(Second Embodiment)
The mounted object replacement method according to the present embodiment transfers the mounted object that the first flying object has to the second flying object. Since the configuration of each flying object has the same configuration as that of the first embodiment, description thereof is omitted.

  Similar to the first embodiment, the moving method is performed as follows. First, the first flying object is positioned below the second flying object.

  At this time, the relative positions of the first flying object and the second flying object are locked. As a locking method, a physical method may be used, or the positions of each other may be locked by software.

  As shown in FIGS. 6-8, in the locked state, each of the rotation ranges of the propeller of the first air vehicle (the element that generates the wake) is at least partially with respect to the propeller of the second air vehicle. It is maintained in a non-overlapping state. Accordingly, at least the wake region B2 of the upper second flying object does not overlap with the wake region B1 of the lower flying object.

  Subsequently, the load L in the loading unit of the first flying object is pulled up to the loading unit of the second flying object. Thereby, the movement of the luggage L from the first flying object to the second flying object is completed.

  In the present embodiment, when the positions of the first flying object and the second flying object are relatively locked, the horizontal direction is shifted by approximately 45 degrees. Thereby, it becomes possible to minimize the disturbance of the wake of the propeller.

(Third embodiment)
As shown in FIG. 5, at the time of takeoff (initial state), the flying body takes off in a state (stacked state) in which the first flying body (master aircraft) and the second flying body (child aircraft) are stacked. .

  Since the airframes are connected to each other, the shape can be regarded as a pseudo octocopter in the stacked state.

  At the time of flight, the battery of the parent device may be prioritized and consumed. Thereby, the subunit | mobile_unit can start operation by a full charge at the time of isolation | separation.

  The slave unit can be separated (detached) from the master unit, and can be combined (docked) with another master unit (second master unit).

Hereinafter, the state at the time of takeoff and at the time of flight will be described in two patterns.
A: A parent device (stacks child devices) and B: A child device (having baggage L). In the following, “A” represents the parent device, “B” represents the child device, and the subscript numbers are individual.
<Pattern 1>
At takeoff A1 + B1 (stacked)
In flight B1 (separated from A1)
At takeoff, the main unit A1 and the sub unit B1 fly in a combined state. In the sky, the child device B1 is separated from the parent device A1 (see FIG. 5B).
<Pattern 2>
At takeoff A1 + B1 (stacked)
In flight B1 (separated from A1)
Distance extension 1 B1 + A2 (coupled to other base unit A2)
Base unit 2 separation B1 (separated from A2)
Distance extension 2 B1 + A3 (Further connected to other base unit A3)
Base unit 2 separation B1 (separated from A3)
As shown in FIG. 5 (c), at the time of takeoff, the main unit A1 and the sub unit B1 fly in a combined state (takeoff 1). After flying for a predetermined time in the sky, the slave unit B1 is separated from the master unit A1 (separation 2). The slave unit B1 is coupled to the other master unit A2 (couple 3). Up to this point, the pattern 2 is the same as the pattern 2 shown in FIG. When the flight distance is further increased in a state where the parent device A2 and the child device B1 are combined, the child device B1 is separated from the parent device A2 (separation 5). In the coupled state, the propeller of only the parent device (or the propeller of the child device) may be rotated only by the power source (battery) of the parent device. Further, the state of the battery of the slave unit may be detected, and the battery of the slave unit may be charged from the battery of the master unit accordingly.

  By carrying the luggage L on the slave unit and guiding the new master unit when the remaining battery level is low, it is possible to deliver the product over a long distance, which is impossible by itself.

<Configuration according to this embodiment>
A flying object comprising a first flying object and a second flying object that can be connected to and detached from the first flying object,
A flying object configured to be detachable from the second flying object in the air.

(Fourth embodiment)

  In the fourth embodiment, the power of the flying object in the third embodiment is changed from a power source derived from electric power such as a motor to an internal combustion engine. At the time of take-off (initial state), the flying body takes off in a state where the first flying body (master aircraft) and the second flying body (child aircraft) are stacked (stacked state) (example of aircraft structure: FIG. 6 to FIG. (Shown in FIG. 8).

  The power source of the parent machine is an internal combustion engine.

  In the stacked state, the shape is a pseudo octocopter.

  At the time of flight, priority is given to the battery of the parent machine to consume power. Thereby, the subunit | mobile_unit can start operation by a full charge at the time of isolation | separation.

  The slave unit can leave the master unit and dock with another master unit (second master unit).

Hereinafter, the state at the time of takeoff and flight will be described.
A: A parent device (stacks child devices) and B: A child device (having baggage L).
<Pattern 1>
At takeoff A1 + B1 (stacked)
In flight B1 (separated from A1)
<Pattern 2>
At takeoff A1 + B1 (stacked)
In flight B1 (separated from A1)
Distance extension 1 B1 + A2
Base unit 2 separation B1 (separated from A2)
Distance extension 2 B1 + A3
Base unit 2 separation B1 (separated from A3)

  By carrying the luggage L on the slave unit and guiding the new master unit when the remaining battery level is low, it is possible to deliver the product over a long distance, which is impossible by itself.

<Configuration according to this embodiment>
A flying object comprising a first flying object that uses an internal combustion engine as a power source, and a second flying object that can be connected to and detached from the first flying object,
A flying object configured to be detachable from the second flying object in the air.

  In the fifth embodiment, the flying body in the third embodiment is changed from a rotary wing aircraft to a fixed wing aircraft. At the time of take-off (initial state), the flying body takes off in a state (stacked state) in which the first flying body (master aircraft) and the second flying object (child aircraft) are stacked.

  The main aircraft is a fixed wing aircraft. That is, the main wing is fixed to the aircraft, and the aircraft advances to generate lift and fly.

  In the stacked state, the shape is a pseudo octocopter.

  At the time of flight, priority is given to the battery of the parent machine to consume power. Thereby, the subunit | mobile_unit can start operation by a full charge at the time of isolation | separation.

  The slave unit can leave the master unit and dock with another master unit (second master unit).

Hereinafter, the state at the time of takeoff and flight will be described.
A: A parent device (stacks child devices) and B: A child device (having baggage L).
<Pattern 1>
At takeoff A1 + B1 (stacked)
In flight B1 (separated from A1)
<Pattern 2>
At takeoff A1 + B1 (stacked)
In flight B1 (separated from A1)
Distance extension 1 B1 + A2
Base unit 2 separation B1 (separated from A2)
Distance extension 2 B1 + A3
Base unit 2 separation B1 (separated from A3)

  By carrying the luggage L on the slave unit and guiding the new master unit when the remaining battery level is low, it is possible to deliver the product over a long distance, which is impossible by itself. In addition, since the base unit has fixed wings, it is possible to deliver the luggage L farther.

  Subsequently, the load L in the loading unit of the first flying object is pulled up to the loading unit of the second flying object. Thereby, the movement of the luggage L from the first flying object to the second flying object is completed.

  As shown in FIGS. 9 and 10, the first flying object can change the distance between the motors (motor span) in the sky. That is, the length (from the center) of the motor arm is variable (or different lengths from the beginning for the first flying object and the second flying object). Thereby, when viewed from the vertical direction, the propellers of the first flying object and the second flying object do not overlap, so that the flight efficiency can be improved.

  The motor span may be variable for only the first aircraft, only the second aircraft, and both the first and second aircraft.

With reference to FIGS. 127 to 129, a simple VR drone provided with photographing units V before and after the aircraft is provided.

  The flying object according to the present embodiment is particularly suitable for an extremely narrow flight environment, or when the right and left image quality is not important (such as a drone race).

(82nd embodiment)
As shown in FIGS. 130 to 132, a reverse mode of the VR camera-equipped machine is provided.

  It is a part of the functions of the aircraft equipped with the drone maneuvering method regardless of the actual flight posture. Pressing the “reverse button” on the propo side reverses the direction of travel by 180 °. It is suitable for applications such as going back and forth inside a pipe.

(83th embodiment)
Provides home position mode for VR cameras.

  Pressing the “Home position button” reverses the direction of travel by 180 °. It has an auxiliary function when the pilot position (home position) is unclear. Press the home position switch and perform “forward” to return to the pilot.

(84th embodiment)
A GPS antenna mounted on a VR shooting drone is provided.

  It is the GPS antenna of the 77th embodiment (landing method of VR photographing drone equipped with two sets of cameras).

When the flight mode is changed to the landing mode, the GPS antenna is tilted. It functions as a mechanism for canceling this inclination.

(85th embodiment)
A 4-axis gimbal for a camera mounted at a position away from the center of gravity of the aircraft is provided.

With the existing 3-axis gimbal, the camera moves up and down if the aircraft tilts when hovering. This disturbance is noticeable in close-up aerial photography.

In order to cancel this, an axis that cancels the vertical movement of the camera is added.
This idea is very effective in short-distance hovering shooting using a quadcopter, multicopter, or octocopter equipped with a camera at a position away from the center of gravity of the aircraft.

In order to achieve a perfect effect, it is preferable to employ a 6-axis gimbal.

(86th embodiment)
As shown in FIGS. 133 to 135, a stabilizer optimized for short-distance aerial photography using a multicopter is provided.

  It is a stabilizer that assumes a small quadcopter.

A lens unit is mounted at the forward position at the bottom of the aircraft using a saddle-shaped arm.

  The stabilizer motor is installed near the position of the center of gravity, and realizes a multicopter in which the three-dimensional position of the camera does not move even if attitude control is entered during hovering. The tilt / roll axis exists near the center of gravity. The pan axis is near the camera.

(87th embodiment)
Provide ceiling charging drone. The mounting part and the flying part can be displaced independently.

  As shown in FIGS. 136 to 138, the following configuration is provided. A charging mechanism is installed at the top of the aircraft. Restrain the aircraft from the charging port side. The restraining method includes magnetic adhesion and mechanical type, but is not limited thereto. Charging can be done with or without contact.

(Eighth Embodiment)
As shown in FIGS. 139 to 141, a ceiling drone charger is provided. The flying object is installed on the ceiling. Power is distributed from the existing crescent. The flying object is fixed to the ceiling by being magnetically attached to the metal part of the ceiling.

(89th embodiment)
As shown in FIGS. 142 to 144, a drone is provided that includes a visual lamp on a bar that maintains vertical.

  A plurality of LED identification lights are provided in the vertical bar portion.

  In conventional aircraft, there are conditions in which the nose lights and tail lights can all be seen from the pilot position, and the traveling direction of the aircraft may be lost. In the case of the installation position of the present invention, it is possible to adjust the irradiation range of the taillight strictly. It becomes possible to grasp.

(90th embodiment)
Provide a method for guiding intersections on drone routes.

Rules for drones not touching at intersections on the route ・ In the vicinity of an intersection, priority is given to the intersection guidance system for the Z-axis control. ・ Assume that the aircraft on the A route flies up and the B route flies down. The aircraft on the route can only be operated by the aircraft's judgment. · The aircraft on the B route can be operated only by the aircraft's judgment. · Both aircraft can fly freely within the range permitted by the route.

(91st embodiment)
A mechanism to correct the center of gravity of the load of a delivery drone using a biaxial gimbal mechanism is provided. This is a modification of the 73rd embodiment.

  In a balance adjustment mechanism using a brushless motor, the mechanism may not work if the center of gravity of the load deviates greatly from the design value.

  Moreover, in the state where the balance is lost, power is consumed to maintain the posture more than necessary.

  The purpose of the balance adjustment mechanism on the aircraft is to support various loads.

  When packing the load in a box, placing the X and Y axes near the center is relatively easy to balance, but it is difficult to adjust the Z axis, so this proposal focuses on adjusting the Z axis. Put.

  Add one or more balance correction mechanisms.

(92nd embodiment)

  A method for stabilizing the load of a delivery drone using a biaxial gimbal mechanism is provided.

If the drone changes its position in the sky, G will add an unexpected weight to the load.

Specifically, the contents of home delivery are biased.

  In order to counter this, the inclination of the luggage L changes in a direction to cancel out the occurrence of G.

  The above-described embodiments are merely examples for facilitating understanding of the present invention, and are not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
