Description

Technical Field

[0001] The present invention relates to the field of aerospace technology, and in particular to a terminal delivery device for an unmanned aerial vehicle. Background Art

[0002] The rapid development of e-commerce has caused traditional ground logistics terminal delivery to encounter problems such as traffic congestion, high costs, and lack of manpower. However, drones have made continuous breakthroughs in control, navigation and other technologies, and their flexible and efficient advantages are in line with delivery needs. Against this background, drone terminal delivery devices have become a new option for solving the difficulties of logistics terminals.

[0003] The drone terminal delivery device is usually composed of a flight system, a cargo loading system, a navigation control system, etc. When working, the ground control center plans the route and sends instructions according to the delivery task. After receiving the instructions, the drone relies on the navigation control system to fly along the planned route. During the flight, it uses sensors to perceive the environment and adjust its posture. When encountering obstacles, it performs obstacle avoidance operations and lands accurately after reaching the destination. The operator completes the unloading of cargo manually or through simple mechanical devices.

[0004] The cargo loading boxes of traditional drone terminal delivery devices generally adopt an integrated single-space design. Although this structure can meet basic loading needs, it lacks internal zoning planning, resulting in the inability to effectively separate multiple varieties and categories of goods during loading. In the actual delivery process, the mixing of fresh food and ordinary goods can easily cause contamination, and during the storage and retrieval process, the operator needs to reach into the cargo loading box to store and retrieve the goods, which is inconvenient to operate, not conducive to improving storage and retrieval efficiency, and reduces the convenience of using the delivery device.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to the attached Figure 3 - attached Figure 5, an embodiment of the present invention provides an end - delivery device for a drone, which includes a housing 1. A mounting arm one 2 is evenly and fixedly connected to the outside of the housing 1. A flight control module 16 is installed inside the housing 1, and a power supply 17 is installed at the bottom of the power supply 17. A pair of mounting arms two 3 are symmetrically and fixedly connected to the bottom of the housing 1. A delivery bin 5 is installed between the pair of mounting arms two 3. A support block 4 is installed at the bottom of the mounting arm two 3. A buffer assembly 8 is arranged inside the support block 4. A convex block 10 is fixedly connected to the inner wall of the delivery bin 5. A storage box 11 is slidably connected to the side of the convex block 10 away from the delivery bin 5. A disassembly assembly 6 is arranged between the delivery bin 5 and the storage box 11. A heat dissipation assembly 7 is arranged inside the housing 1. A micro - motor 14 is installed at the end of the mounting arm one 2 away from the housing 1. A propeller 15 is fixedly connected to the output end of the micro - motor 14. An installation assembly 9 is arranged inside the mounting arm one 2; The disassembly assembly 6 includes an adapter block 61. The adapter block 61 is fixedly connected to the bottom of the storage box 11. A pressing block 62 is rotatably connected to the end of the adapter block 61 away from the storage box 11. An insertion block 63 is fixedly connected to the top of the pressing block 62. A spring piece 64 is installed between the storage box 11 and the pressing block 62. A slot 65 is opened at the bottom of the convex block 10. The insertion block 63 is slidably connected to the middle of the slot 65. The delivery bin 5 is fixedly connected directly below the housing 1. A handle 12 is fixedly connected to the outside of the storage box 11. Buffer pads 13 are evenly arranged inside the storage box 11. The delivery bin 5 and the storage box 11 are connected by the disassembly assembly 6. Buffer pads 13 are evenly arranged inside the storage box 11. The delivery bin 5 and the storage box 11 are connected by the disassembly assembly 6.

[0032] Specifically, the power supply 17 stably powers core components such as the flight control module 16 and the micro motor 14. After receiving the command signal from the ground control center, the flight control module 16 regulates the rotation speed and direction of the micro motor 14. Under the control of the flight control module 16, the micro motor 14 drives the propeller 15 to rotate at high speed and generate lift. As the propeller 15 continues to rotate, the lift accumulates continuously, providing a basic guarantee for the stable flight of the UAV and ensuring the smooth start of the delivery task. By an operator pressing the elastic piece 64 by hand, the elastic piece 64 undergoes elastic deformation under the external force, driving the pressing block 62 connected thereto to rotate with the connecting block 61 as the fulcrum. During the rotation of the pressing block 62, the inserting block 63 fixed to its top gradually moves downward until it completely disengages from the slot 65 at the bottom of the convex block 10. At this time, the locking state between the storage box 11 and the delivery bin 5 is released, and the operator can smoothly pull out the storage box 11 from the delivery bin 5 along the convex block 10. After pulling out the storage box 11, the goods to be delivered are placed on the buffer pad 13 laid inside. The buffer pad 13 is made of an elastic material and absorbs external impact force through its own deformation, reducing the collision between the goods and between the goods and the inner wall of the storage box 11. After placing the goods, the operator pushes the storage box 11 back to the designated position inside the delivery bin 5 along the convex block 10, and then releases the hand pressing the elastic piece 64. The elastic piece 64 restores its deformation relying on its own elasticity, driving the pressing block 62 to rotate in the reverse direction, and the inserting block 63 moves upward accordingly and is inserted into the slot 65, completing the rapid fixed installation of the storage box 11 inside the delivery bin 5. The elastic piece 64 is specifically made of stainless steel or titanium alloy to improve fatigue resistance. This method realizes the classified loading of multi-category goods, avoiding the pollution problem caused by the mixed loading of fresh food and ordinary goods. At the same time, through simple operations of pressing, pulling, and releasing, it helps to improve the efficiency of goods access and storage, and solves the problem of inconvenient goods access and storage of traditional devices.

[0033] Please refer to the attached Figure 1 - attached Figure 3 As shown in the figure, the heat dissipation component 7 includes a fan 71. The fan 71 is installed on one side of the delivery bin 5. On the other side of the delivery bin 5, a heat sink 72 is fixedly connected. One end of the heat sink 72 away from the delivery bin 5 is fixedly connected with a heat dissipation ring 73. Heat dissipation holes 74 are evenly formed in the middle of the heat dissipation ring 73.

[0034] Specifically, by starting the continuous operation of the fan 71, a directional air flow is generated to blow air towards the distribution bin 5, forcing the air to flow inside the device. The heat generated by the operation of the distribution bin 5 and the surrounding equipment is first conducted to the heat sink 72 closely connected to it. The heat sink 72 increases the heat exchange area through a large-area metal material, quickly absorbs the heat and distributes it evenly. Subsequently, the heat is transferred from the heat sink 72 to the heat dissipation ring 73. The heat dissipation ring 73 is in a ring structure surrounding the outside of the distribution bin 5 to further disperse the heat. Finally, the heat is discharged into the external environment in the form of convection through the heat dissipation holes 74 evenly opened in the middle of the heat dissipation ring 73. This heat dissipation structure forms a complete heat dissipation cycle system through the coordinated operation of the fan 71 for active air supply, the heat sink 72 for efficient heat conduction, the heat dissipation ring 73 for uniform heat distribution, and the heat dissipation holes 74 for rapid heat dissipation, preventing performance degradation or even failure due to excessive temperature, and ensuring that all components of the UAV terminal distribution device are always in an appropriate working temperature range during long-term operation.

[0035] Please refer to the attached Figure 6 - attached Figure 7 As shown in the figure, the buffer assembly 8 includes a slider 81. The slider 81 is fixedly connected to the bottom of the second mounting arm 3. A cylinder 82 is fixedly connected inside the support block 4. A cylinder 83 is slidably connected inside the cylinder 82. A compression spring 84 is installed inside the cylinder 82. The compression spring 84 abuts between the cylinder 82 and the cylinder 83.

[0036] Specifically, through the connection structure of the slider 81 between the support block 4 and the second mounting arm 3, the support block 4 can slide within a certain range, providing a movement space for the buffering process. When the UAV lands instantaneously, the second mounting arm 3 drives the slider 81 to transfer the impact force to the support block 4. The cylinder 83 slides into the cylinder 82 under the action of the impact force, gradually compressing the compression spring 84. As the compression spring 84 is compressed, its elastic potential energy continuously increases, converting the kinetic energy generated by the UAV's landing into elastic potential energy to offset most of the impact force. When the impact force weakens, the compression spring 84 pushes the cylinder 83 to reset by virtue of its own elastic restoring force, returning the support block 4 to its initial state. This method helps to avoid damage to the goods in the distribution bin 5 due to severe impact, reduce the stress borne by the UAV body structure, and contribute to ensuring the safety and stability of the UAV during frequent takeoffs and landings.

[0037] Please refer to the attached Figure 1 and attached Figure 8, the installation component 9 includes an installation post 91. The installation post 91 is fixedly connected to one end of the first installation arm 2 away from the housing 1. A moving rod 92 is slidably connected inside the installation post 91. A limiting piece 94 is fixedly connected to the outer side of the moving rod 92. A spring 95 is installed inside the installation post 91. The spring 95 abuts between the moving rod 92 and the limiting piece 94. The limiting piece 94 is slidably connected to the inner wall of the installation post 91. A limiting hole 93 is opened on one side of the micro motor 14 close to the moving rod 92. The moving rod 92 is slidably connected to the middle of the limiting hole 93.

[0038] Specifically, the first installation arm 2 constructs a connection carrier between the power component and the housing 1. Inside the installation post 91 provided inside the first installation arm 2, the moving rod 92 can slide axially. When installing the micro motor 14, under the pre-tightening force of the spring 95, the moving rod 92 aligns with and inserts into the limiting hole 93 opened on the side of the micro motor 14. At the same time, the limiting piece 94 forms a sliding fit with the inner wall of the installation post 91, restricting the radial displacement of the moving rod 92, thereby firmly fixing the micro motor 14 at the end of the first installation arm 2, ensuring the stable operation of the micro motor 14, and avoiding loosening caused by vibration or external force. When the micro motor 14 needs to be disassembled and repaired, the operator pulls the moving rod 92 backward. The moving rod 92 drives the limiting piece 94 to move synchronously and compresses the spring 95, causing the spring 95 to undergo elastic deformation to generate a compressive force. As the moving rod 92 continues to move backward, it completely disengages from the limiting hole 93, releasing the limiting constraint on the micro motor 14. At this time, the micro motor 14 can be quickly removed from the first installation arm 2. This method ensures the stability of the power system of the drone, helps to shorten the equipment maintenance time, and reduces the difficulty of maintenance operations.

[0039] Working principle: When the end delivery device of the drone executes a task, the power supply 17 supplies power to components such as the flight control module 16 and the micro motor 14. The flight control module 16 controls the micro motor 14 to drive the propeller 15 to rotate according to the instructions of the ground control center, generating lift to make the drone take off. The first installation arm 2 connects power components such as the micro motor 14 to the housing 1. The moving rod 92 is inserted into the limiting hole 93 of the micro motor 14 to limit the micro motor 14. When the micro motor 14 needs to be disassembled and repaired, pull the moving rod 92 backward. The moving rod 92 drives the limiting piece 94 to move. The limiting piece 94 compresses the spring 95. Subsequently, the moving rod 92 disengages from the limiting hole 93, and the micro motor 14 can be quickly removed;

[0040] During flight, the support block 4 is connected to the second installation arm 3 through the slider 81. The cylinder 82, the cylinder 83 and the compression spring 84 form a buffer structure, which can effectively absorb the impact force when the drone lands. During the delivery process, the fan 71 in the heat dissipation component 7 blows air into the delivery bin 5, and the heat is transferred to the heat dissipation ring 73 through the heat dissipation fins 72 and discharged through the heat dissipation holes 74;

[0041] When storing goods, the operator presses down on the elastic piece 64. The elastic piece 64 deforms under the force, and the pressing block 62 rotates around the connecting block 61, causing the inserting block 63 to move downward and gradually disengage from the slot 65, enabling the storage box 11 to move freely. Subsequently, the storage box 11 is pulled out of the distribution bin 5 along the convex block 10, and goods are placed inside. The buffer pad 13 provides a certain degree of protection for the goods. After that, when the storage box 11 is pushed to the designated position, the elastic piece 64 is released. The elastic piece 64 resets and drives the inserting block 63 to engage with the slot 65, achieving rapid disassembly and shipment.
