DETAILED DESCRIPTION

[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0039] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present application belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit exemplary embodiments according to the present invention.

[0040] The embodiment of the present invention aims at the defects and deficiencies in the execution of long-distance airdrop and air delivery tasks under the current harsh conditions, and provides a cargo automatic delivery system in the cabin of an unmanned aircraft. The cargo automatic delivery system is installed in the cabin of an unmanned aircraft to realize the automatic delivery of cargo in the cabin of an unmanned aircraft. The life safety problem of the pilot and crew members when the aircraft performs an airdrop mission under harsh conditions is solved, and the intelligent implementation of the airdrop mission is realized, so that the implementation of the delivery mission can be standardized, thereby improving the delivery success rate.

[0041] like Figure 1 and Figure 2 As shown, a cargo automatic delivery system in an unmanned aerial vehicle cabin, the cargo automatic delivery system 2 is installed on the cabin floor inside the unmanned aerial vehicle cabin 1, and the cargo automatic delivery system 2 includes: a material delivery structure 5 and a material storage structure 4; the material delivery structure 5 is located inside the unmanned aerial vehicle cabin 1 and directly faces the unmanned aerial vehicle cabin door 3, and is used to deliver materials 6 to be delivered; the material storage structure 4 is located inside the unmanned aerial vehicle cabin 1 along the heading direction, and is used to store materials 17 in the storage area, and after the material delivery structure 5 delivers the materials 6 to be delivered, the storage area materials 17 are transported to the material delivery structure 5.

[0042] like Figure 3 and Figure 4 As shown, the material delivery structure 5 includes a delivery platform 13 and a double-row module 14; the surface of the delivery platform 13 is used to place the materials 6 to be delivered; the double-row module 14 is installed at the lower position of the delivery platform 13, and the two may not be in contact. When the double-row module 14 moves, it will not drive the delivery platform 13 to move together. A delivery push rod assembly 12 is provided at one end of the double-row module 14 away from the unmanned aerial vehicle cabin door 3; a slide groove is provided on the delivery platform 13, and the slide groove penetrates the upper and lower surfaces of the delivery platform 13, and is arranged on the delivery platform 13 along a straight line toward the direction of the unmanned aerial vehicle cabin door, and the middle part of the delivery push rod assembly 12 is vertically arranged in the slide groove; the upper part of the delivery push rod assembly 12 is located above the delivery platform 13, and is used to push the materials 6 to be delivered on the delivery platform 13 toward the direction of the unmanned aerial vehicle cabin door 3 under the drive of the double-row module 14 to achieve delivery. The two sides of the delivery platform 13 are provided with a push limit lock 11 and a delivery zone long guide rail 15. The push limit lock 11 is used to push or retract in the direction of the delivery zone long guide rail 15, thereby limiting or releasing the materials to be delivered 6; the delivery zone long guide rail 15 is used to limit the movement direction of the materials to be delivered 6, so that the delivery push rod assembly 12 pushes the materials in the direction of the drone cabin door. A delivery limit lock 16 is provided at one end of the delivery platform 13 close to the drone cabin door 3, which is used to limit the materials to be delivered 6 before delivery begins.

[0043] Through the above-mentioned arrangement, the propulsion limit lock 11, the delivery push rod assembly 12, the delivery area long guide rail 15, and the delivery limit lock 16 can limit and lock the posture of the material 6 to be delivered before delivery, and can also correct the material. In this way, it can be ensured that each time the material is delivered, it can be delivered in a fixed preset posture and position, thereby ensuring the delivery success rate.

[0044] In a preferred embodiment, a short guide rail 7 is also provided in the delivery area. The short guide rail 7 is arranged opposite to the long guide rail 15 in the delivery area. The short guide rail 7 in the delivery area is located on a side close to the cabin door of the drone and is used for the delivery of auxiliary materials.

[0045] like Figure 6 and Figure 7 As shown, the double-row module 14 includes a belt drive module 18, a slide 20 and a drive assembly; the slide 20 is mounted on the belt drive module 18, and the drive assembly is used to drive the belt drive module 18 so as to realize the slide 20 to reciprocate along a straight line on the belt drive module 18. The bottom of the belt drive module 18 is connected to a double-row module connecting base 19, and the double-row module connecting base 19 is used to fix the position of the belt drive module 18.

[0046] As a specific example of the above embodiment, the driving assembly includes a servo motor 21, a reducer 22, a module connecting shaft 23, a driving pulley 24, a driven pulley 25 and a synchronous belt 26. The servo motor 21 inputs power into the driving pulley 24 through the reducer 22 and the module connecting shaft 23. The driving pulley 24 drives the synchronous belt 26 to move, and the synchronous belt 26 then transmits the motion to the slide 20 and the driven pulley 25.

[0047] Through the above arrangement, the reducer 22 can increase the torque input into the driving pulley 24, and the belt transmission can increase the lead of the module, thereby increasing the running speed of the slide. Therefore, the reducer 22 and the belt transmission module 18 are used in combination to increase the weight of a single material delivery and the speed of the material delivery out of the cabin. The two belt transmission modules 18 are directly connected through the module connection shaft 23, thereby ensuring the synchronization of the movement of the two belt transmission modules 18.

[0048] As a specific example, the servo motor 21 can be a DC motor. By setting the power output mode to a DC motor acceleration and reduction gear, a large torque output can be achieved under the onboard power supply condition (DC28V). This can increase the thrust of the cargo delivery device and can adapt to a larger single delivery weight of materials.

[0049] At the same time, the delivery execution functional component is belt-driven (the power is output from the servo motor and the reducer to the synchronous pulley at the drive end, the driving pulley transmits the motion to the synchronous belt, and the synchronous belt drives the driven pulley to rotate, forming the structure of the entire delivery execution functional component). This can achieve the large lead operation of the delivery execution functional component, thereby achieving low speed of the input drive pulley, and the module slide can output high linear speed. In addition, the delivery method adopts a double-row module structure. The two-row modules are connected in parallel through the transmission shaft to realize a power input to the double-row modules. The double-row modules can move synchronously, which can improve the stability of the cargo when it needs to be delivered at a short distance and high speed when exiting the hatch.

[0050] As a preferred embodiment of the above embodiment, three double-row module connecting bases 19 are respectively connected to the front, middle and rear positions of the two belt drive modules 18, so as to ensure the parallelism of the two belt drive modules 18 along the movement direction. The two belt drive modules 18 can be used in parallel to ensure stability during high-speed delivery.

[0051] When materials are delivered, the delivery limit lock 16 is unlocked, the servo motor 21 drives the double-row module 14 to work, and the delivery push rod assembly 12 installed on the slide 20 pushes the materials 6 to be delivered out of the cabin from the drone cabin door 3 to complete the delivery task.

[0052] like Figure 3 to Figure 5 As shown, the material storage structure 4 includes a side guide rail assembly 8, a bottom guide rail 9 and a power output unit 10; the side guide rail assembly 8 includes two oppositely arranged side guide rails, and the outlet of the side guide rail assembly 8 is opposite to the position of the delivery platform 13; the bottom guide rail 9 is arranged between the two side guide rails and parallel to the side guide rails, and is used to carry and transport the storage area materials 17; the power output unit 10 is arranged between the two side guide rails, and is used to drive the storage area materials 17 to move along the bottom guide rail 9 toward the delivery platform 13.

[0053] It should be noted that the power output unit 10 mentioned in this solution can also be configured as a structure similar to a double-row module, or adopt other types of transmission structures in the field, which will not be described in detail here.

[0054] After the materials to be delivered 6 are delivered out of the cabin, the propulsion limit lock 11 cooperates with the power output unit 10 to provide transfer power for the storage area materials 17 of the material storage structure 4, and the side guide rail assembly 8 and the bottom guide rail 9 can ensure that the storage area materials 17 are transferred according to the planned route, so that the storage area materials 17 can be smoothly transferred to the delivery platform 13. At this time, the delivery limit lock 16 is locked, and the posture of the storage area materials 17 transferred to the delivery platform 13 can be locked in cooperation with the propulsion limit lock 11, the delivery push rod assembly 12, and the delivery area long guide rail 15. At this time, the storage area materials 17 enter the waiting delivery state. Repeating the above actions can realize the fixed-point airdrop and air delivery task of all materials inside the automatic cargo delivery system 2.

[0055] like Figure 8 As shown, the delivery push rod assembly 12 includes a delivery push plate 27 and a push plate column 29; the delivery push plate 27 is installed on the first end of the push plate column 29 by bolts, and is used to push the materials to be delivered 6, and the second end of the push plate column 29 is fixed to the slide 20 by bolts. In the preferred embodiment, a push plate reinforcement rib 28 is also provided, and the push plate reinforcement rib 28 is connected to the delivery push plate 27 and the push plate column 29 by bolts, and is locked with the delivery push plate 27 and the push plate column 29 through its own "concave" shape structure, so as to realize structural force and ensure the strength of the delivery push rod assembly 12. The delivery push rod assembly 12 realizes the separation of the delivery execution function component and the delivery materials through a simple and compact structure.

[0056] like Fig. 9 As shown, the push limit lock 11 includes an electric limit lock 30, a linear module 31 and a stepper motor 32; the electric limit lock 30 includes a lock seat 302 and a lock tongue 301, the lock seat 302 is provided with a lock tongue mounting groove along the top downward, the first end of the lock tongue 301 is installed in the lock tongue mounting groove in a manner that it can be driven to rotate by a motor, and the lock tongue 301 can be received in the lock tongue mounting groove and extend out of the lock tongue mounting groove in the vertical direction when rotating; the lock seat 302 is slidably installed on the linear module 31 and connected to the output end of the stepper motor 32; by controlling the stepper motor 32, the forward and backward movement of the electric limit lock 30 in the stroke direction of the linear module 31 can be controlled, thereby realizing the function of the push limit lock 11 to push and lock the position of the materials 17 in the storage area.

[0057] Example 2

[0058] A method for automatically delivering cargo in an unmanned aircraft cabin, based on the above-mentioned automatic delivery system for cargo in an unmanned aircraft cabin, comprises the following steps:

[0059] Before the materials are released, the propulsion limit lock 11, the release push rod assembly 12, the release zone long guide rail 15, and the release limit lock 16 are used to limit and lock the posture of the materials 6 to be released before release.

[0060] When delivering, the stepping motor 32 that pushes the limit lock 11 is retracted, and the lock tongue 301 releases the material 6 to be delivered; and the delivery limit lock 16 releases the lock on the material 6 to be delivered.

[0061] The driving assembly drives the belt transmission module 18 to move, and the slide 20 moves on the belt transmission module 18 along a straight line toward the drone cabin door 3; then the slide 20 drives the delivery push rod assembly 12 to move, and the delivery push rod assembly 12 pushes the material to be delivered 6 to move toward the drone cabin door 3, pushing the material to be delivered 6 out of the drone cabin to achieve delivery.

[0062] After the delivery of the to-be-delivered material 6 is successful, the power output unit 10 drives the storage area material 17 to move on the bottom guide rail 9 along the direction of the side guide rail assembly 8 to the push-limit lock 11. At this time, the lock tongue 301 of the push-limit lock 11 rotates and retracts into the lock tongue mounting groove of the lock seat 302, and then the power output unit 10 continues to drive the storage area material 17 until the storage area material 17 is transported to the delivery platform 13; at this time, the lock tongue 301 of the push-limit lock 11 rotates and extends out of the lock tongue mounting groove of the lock seat 302, and the stepper motor 32 of the push-limit lock 11 extends out, driving the lock tongue 301 to press the storage area material 17 on the delivery platform 13, waiting for the next delivery of materials.

[0063] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive.
