< details of the embodiment >

Hereinafter, a flying object according to an embodiment of the present invention will be described with reference to the drawings.

< details of embodiments of the present invention >

As shown in fig. 1, a flight vehicle 1 according to an embodiment of the present invention is a flight vehicle dedicated to service delivery, and includes: a propeller 2 (lift force generating section: rotor); a motor 3 for rotating the propeller 2; an arm 4 to which the motor 3 is mounted; and a mounting portion 5 provided on the arm 4 and mounting the case 6 thereon. The flight vehicle 1 travels in a direction indicated by an arrow D in the drawing (details will be described later).

The propeller 2 rotates upon receiving an output from the motor 3. The propeller 2 rotates to generate a propulsive force for taking off the flying object 1 from the departure place, moving horizontally, and landing at the destination. In addition, the propeller 2 can be rotated to the right, stopped, and rotated to the left.

The blades of the propeller 2 of the present invention have an elongated shape. The number of blades (rotating bodies) may be arbitrary (for example, 1, 2, 3, 4 or more blades). Further, the shape of the blade may be any shape such as a flat shape, a curved shape, a twisted shape, a tapered shape, or a combination thereof. In addition, the shape of the blade can vary (e.g., telescope, fold, bend, etc.). The blades may be symmetrical (having identical upper and lower surfaces) or asymmetrical (having differently shaped upper and lower surfaces). The blades can be formed as airfoils, wings, or geometries suitable for causing the blades to generate aerodynamic forces (e.g., lift, thrust) when moving in the air. The geometry of the blades may be suitably selected to optimize the aerodynamic characteristics of the blades, e.g. increase lift and thrust, reduce drag, etc.

The motor 3 is used to rotate the propeller 2, and for example, the driving unit may include an electric motor or an engine, or the like. The blades may be driven by a motor to rotate in a clockwise direction and/or a counter-clockwise direction about a rotational axis of the motor (e.g., a long axis of the motor).

The blades can all rotate in the same direction, or can rotate independently. Some blades rotate in one direction and others rotate in the other direction. The blades can all rotate at the same rotational speed, but can also each rotate at a different rotational speed. The rotation speed may be automatically or manually determined according to the size (e.g., size, weight), control state (speed, moving direction, etc.) of the moving body.

The arms 4 are members that support the corresponding motor 3 and propeller 2, respectively. In order to indicate the flight state, flight direction, and the like of the rotorcraft, a color body such as an LED may be provided on the arm 4. The arm 4 of the present embodiment can be formed of a material appropriately selected from carbon, stainless steel, aluminum, magnesium, and the like, or an alloy or combination thereof.

The mounting portion 5 is a mechanism for mounting and holding the housing 6. The mounting portion 5 is formed of a pair of members spaced apart from each other at a predetermined interval in the left-right direction. The mounting portion 5 always maintains its state in a predetermined direction (for example, a horizontal direction (vertical downward)) so as to be able to maintain the position and orientation of the mounted box 6.

More specifically, the mounting portion 5 has a hinge (gimbal) 50, and is configured to: the flying object 1 carrying the case 6 is bent along with the inclination of the flying object 1 using the hinge 50 as a fulcrum. The angle at which the hinge 50 is bent is not particularly limited. For example, as shown in fig. 1, the position and direction of the box 6 may be kept horizontal even when the flying object 1 flies in a forward-inclined posture. Thus, the box 6 is always kept in a vertically suspended state, and can be delivered to the destination while maintaining the position and state of the departure point. The hinge 50 of the present embodiment can move only in the same direction as the traveling direction, i.e., the front-rear direction. However, it may be movable in the right and left direction.

Here, the hinge 50 may be controlled by a motor or the like. This can further prevent the housing 6 from shaking (natural vibration or the like) during flight.

The shape and mechanism of the mounting portion 5 are not particularly limited as long as the case 6 can be housed or held, and may be any shape as long as the position of the case 6 mounted on the first mounting portion 30 can be held when the case is tilted. The mounting portion 5 of the present embodiment is provided rearward of the center of gravity Gh of the flying object 1 in the front-rear direction by a predetermined distance L1 in the traveling direction D. The predetermined distance L1 is set so that the case 6 does not partially overlap with a circular region generated by rotation of at least the rear propeller 2 in the vertical direction. In other words, the predetermined distance L1 is set to a value at which the rotating propeller 2 and the casing 6 do not overlap when viewed from above the propeller 2. More preferably, the case 6 is disposed at a position not affected by the wake region generated by the rear propeller 2. The mounting unit 5 can be provided at any position on the arm 4. Further, the position can be changed by sliding movement or the like after the mounting.

When the case 6 of the present invention is placed upright as shown in fig. 2, as shown in fig. 2 to 4, the case includes: an upper surface member 60 and a lower surface member 61 forming an X-Y surface of XYZ coordinate axes, a front surface member 62 and a rear surface member 63 forming an X-Z surface, and side surface members 64 forming both sides of the Y-Z surface. The box body 6 is used for placing goods to be delivered into the interior for carrying. Reference numeral 65 shown in fig. 2 to 4 denotes a pair of covers. Such a case 6 is symmetrical in the front-rear, left-right, and up-down directions as in the case of a general case. Therefore, the upper, lower, front, and rear parts in the component names shown as the upper surface member 60, the lower surface member 61, the front surface member 62, and the rear surface member 63 are used to represent the state when the device is assumed to be placed upright as shown in the drawing.

As shown in fig. 2, the case 6 is opened through a slit 66 extending in the Y direction (longitudinal direction). As shown in fig. 2, the slits 66 are provided at a predetermined interval in the center portion in the X direction (short side direction). Such a slit 66 may be automatically formed at the time of manufacturing the case 6, or may be formed in the case 6 without a slit by using a cutter or the like.

As shown in fig. 2, the case 6 has a groove 67 opened on both sides in the Y direction. The groove 67 is provided to form an inlet through which a neck 71 of the attachment 7 described later can pass.

The attachment 7 is detachable from the case 6. The attachment 7 has a protrusion shape that can be inserted into the groove 67 through the groove 67 and the slit 66 as the entrance and exit. As shown in fig. 6, the attachment 7 is T-shaped in cross section. Thus, the attachment 7 has a certain cross-sectional shape, and therefore can be extrusion-molded by a die. This has the advantage that the attachment 7 can be manufactured at low cost.

As shown in fig. 6, the attachment 7 has a head 70 protruding in the Z direction and a pair of necks 71 protruding in the X direction. The head 70 has a predetermined width in the X direction (see fig. 6) and a predetermined length in the Y direction (see fig. 5). As shown in fig. 5, a hole 72 is formed in the head 70 disposed in the slit 66 of the case 6 at the center portion in the Y direction, and the hole 72 is used for passing a pin 80 for attaching the accessory 7 to the mounting portion 5. The neck portion 71 disposed in the groove portion 67 of the case 6 has a predetermined width in the Z direction (see fig. 5) and a predetermined length in the X direction (see fig. 6).

The method of fixing the attachment 7 to the case 6 is arbitrary, but in the illustrated embodiment, the head 70 of the attachment 7 is held between a pair of covers 65 and pins 80, thereby firmly fixing the attachment 7 to the case 6. That is, in the present embodiment, the portion of the outer cover 65 and the portion of the head 70 are integrally fixed to each other to maintain a firm fixation.

The flight vehicle described above has the functional blocks shown in fig. 5. In addition, the functional blocks of fig. 5 are a minimal reference structure. The flight controller is a so-called processing unit. The processing unit may have more than one processor, such as a programmable processor, e.g., a Central Processing Unit (CPU). The processing unit has a memory, not shown, and can access the memory. The memory stores logic, code, and/or program instructions that are executable by the processing unit to perform one or more steps. The memory may also include, for example, a detachable medium such as an SD card or a Random Access Memory (RAM), or an external storage device. Data acquired from cameras, sensors, etc. may also be transferred directly to and stored in memory. For example, still image and moving image data captured by a camera or the like are recorded in a built-in memory or an external memory.

The processing unit includes a control module configured to control a state of the flying object. For example, the control module controls the propulsion mechanism (motors, etc.) of the flying object to adjust the spatial configuration, velocity and/or acceleration of the flying object with six degrees of freedom (translational movements x, y and z, and rotational movements θ x, θ y and θ z). The control module can control one or more of the states of the mounting unit and the sensors.

The processing unit is capable of communicating with a transceiver unit configured to transmit and/or receive data from one or more external devices (e.g., a terminal, a display device, or other remote controller). The transmitter/receiver unit can use any appropriate communication method such as wired communication or wireless communication. For example, the transmitting/receiving unit may use one or more of a Local Area Network (LAN), a Wide Area Network (WAN), an infrared ray, a wireless, a WiFi, a peer-to-peer (P2P) network, a telecommunication network, a cloud communication, and the like. The transceiver unit can transmit and/or receive one or more of data acquired by sensors, processing results generated by the processing unit, predetermined control data, user commands from a terminal or a remote controller, and the like.

The sensor class of the present embodiment may include an inertial sensor (acceleration sensor, gyro sensor), a GPS sensor, a proximity sensor (e.g., radar), or a visual/image sensor (e.g., camera).

The flight vehicle of the present invention can be expected to be used as a delivery-service-dedicated flight vehicle and an industrial flight vehicle in a warehouse or a factory. The flying object of the present invention can be used in the aircraft-related industry such as a multi-rotor drone, and the present invention can be suitably used in various industries such as the security field, agriculture, infrastructure monitoring, and the like, in addition to the aerial flying object mounted with a camera and the like.

The above embodiments are merely examples for easy understanding of the present invention, and are not intended to limit the present invention. The present invention may be modified and improved without departing from the scope of the invention, and the invention naturally includes equivalents thereof.
