Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) cargo rack technology, specifically a UAV cargo rack with automatic throwing function. Background Technology

[0002] With the rapid development of drone technology, its application in logistics transportation, emergency rescue, and material delivery is becoming increasingly widespread. As the core component for carrying and delivering materials, the performance of the drone cargo rack directly affects the efficiency and safety of drone operations.

[0003] Currently, most mainstream drone cargo racks on the market suffer from insufficient stability when performing automatic cargo delivery. Specifically, the design of the delivery support structure in most cargo racks is unreasonable, often employing a single locking or simple flipping mechanism. At the moment of unlocking and delivery, the support components are prone to violent shaking due to uneven force, causing the cargo box to deviate in attitude when leaving the cargo rack, affecting delivery accuracy. On the other hand, their functions are relatively limited, with most cargo racks only capable of one delivery, failing to flexibly meet the needs of delivering materials in separate deliveries. Therefore, this application proposes a drone cargo rack with automatic delivery function to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a drone cargo hold rack with automatic throwing function, thus solving the technical problems mentioned in the background.

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1-5 As shown, this utility model provides a technical solution: a drone cargo hold frame with automatic throwing function, including an upper cargo hold frame 1 and a lower cargo hold frame 2, which are vertically connected together. The top of the upper cargo hold frame 1 is connected to a mounting base on the bottom side of the drone. The bottom of both the upper and lower cargo hold frames 1 and 2 are provided with two split support frames 3, and the outer sides of the two split support frames 3 are connected to the upper or lower cargo hold frame 1 via shafts. The front ends of the two split support frames 3 are each provided with a slot 4. Each of the upper and lower cargo hold frames 2 has a sliding locking tongue 5 at its front end, which engages with the slots 4 at the front ends of the two split support frames 3. The locking tongue 5 is driven by an electric push rod 6. After the locking tongue 5 separates from the slots 4 at the front ends of the two split support frames 3 under the push of the electric push rod 6, the two split support frames 3 rotate around the shaft to the upright position. The vertical frame sliding limit frames 7 at the four corners of the upper and lower cargo hold frames 1 and 2, after reserving space on the sides of the upper and lower cargo hold frames 1 and 2 to accommodate the cargo box, allow the cargo box to be placed from the upper or lower cargo hold frame 1. 2. Push in from the side until it fits the internal limiting structure of the frame. This allows for the vertical loading of standard cargo boxes. When loading standard cargo boxes twice, activate the electric push rod 6 of the lower cargo hold 2. The electric push rod 6 pushes the locking tongue 5 to separate from the slot 4 at the front end of the support frame 3. The support frame 3 rotates around the shaft to an upright position. The cargo box in the lower cargo hold 2 is then released downwards under gravity. Then, activate the electric push rod 6 of the upper cargo hold 1. The electric push rod 6 pushes the locking tongue 5 to separate from the slot 4 at the front end of the support frame 3. The support frame 3 rotates around the shaft to an upright position. When switched to the upright position, the cargo boxes in the upper cargo rack 1 are directly detached and dropped downwards under the action of gravity, realizing the two-stage splitting and dropping of the cargo boxes. It can also make the cargo boxes detach directly downwards from the cargo rack, avoiding the deviation of the cargo box posture due to structural shaking during the dropping process, ensuring that the materials are accurately delivered to the target area, and greatly improving the dropping accuracy. The layered design of the upper and lower cargo racks can store the goods separately, and each of the two cargo racks is equipped with an independent dropping mechanism. The single cargo rack can be controlled to operate independently as needed to complete two orderly drops, meeting the needs of various material delivery scenarios.

[0024] Square limiting frames 7 slide on the vertical frames at the four corners of both the upper cargo hold 1 and the lower cargo hold 2. These frames are used to limit the movement of cargo boxes placed inside the upper cargo hold 1 and the lower cargo hold 2. Bolts are installed on the limiting frames 7 for tightening and fixing. The limiting frames 7 can slide upwards or downwards on the vertical frames at the four corners of the upper cargo hold 1 and the lower cargo hold 2, allowing cargo boxes to be loaded from the sides of the upper cargo hold 1 and the lower cargo hold 2. The fixing bolts on the limiting frames 7 can be loosened. The bolts and sliding limiting frames 7 at the four corners of the upper cargo hold frame 1 and the lower cargo hold frame 2 allow for the insertion of cargo boxes. After reserving space on the sides of the upper cargo hold frame 1 and the lower cargo hold frame 2 to accommodate the cargo boxes, the cargo boxes are pushed in from the side of the upper cargo hold frame 1 or the lower cargo hold frame 2 until they fit the internal limiting structure of the frame. This allows for the vertical loading of conventional cargo boxes. The upper cargo hold frame 1, the lower cargo hold frame 2, the support frame 3, and the limiting frame 7 are all made of aluminum alloy and have anodized surfaces.

[0025] The middle connection between the rear sides of the upper cargo hold 1 and the lower cargo hold 2 is frameless, allowing larger cargo boxes to be loaded from the rear sides of the upper cargo hold 1 and the lower cargo hold 2. For larger cargo boxes, the frameless design at the middle of the rear side between the upper cargo hold 1 and the lower cargo hold 2 is utilized. Figure 4 As shown, the limiting frame 7 on the upper cargo hold 1 can be pushed upwards, and the limiting frame 7 on the lower cargo hold 2 can be pushed downwards. At this time, the rear sides of the upper cargo hold 1 and the lower cargo hold 2 are open, and the two support frames 3 at the bottom of the upper cargo hold 1 can be unfolded. At this time, the upper cargo hold 1 and the lower cargo hold 2 will be connected to form a cargo compartment. The cargo box can be smoothly placed into the upper cargo hold 1 and the lower cargo hold 2 from the rear. After loading, it is as follows: Figure 3 As shown, it can drop larger cargo boxes in a single operation. After the drone carrying the cargo rack flies to the target delivery area, it triggers the corresponding cargo rack's dropping command according to the delivery requirements. When dropping a larger cargo box in a single operation, the electric push rod 6 of the lower cargo rack 2 is activated. The electric push rod 6 pushes the locking tongue 5 to separate from the slot 4 at the front end of the support frame 3. The support frame 3 rotates around the shaft to the upright position, and the larger cargo box is directly dropped downwards under the action of gravity.

[0026] The operational steps for this application are as follows:

[0027] Align the top of the upper cargo rack 1 with the mounting base on the bottom side of the drone, and secure it with bolts or adapter connectors to ensure that the cargo rack and the drone are firmly connected and without loosening.

[0028] Loosen the fixing bolts on the limiting frame 7, slide the limiting frame 7 along the vertical frame at the four corners of the upper cargo hold frame 1 and the lower cargo hold frame 2, and after leaving space on the sides of the upper cargo hold frame 1 and the lower cargo hold frame 2 to accommodate the cargo box, push the cargo box into the upper cargo hold frame 1 or the lower cargo hold frame 2 until it fits against the internal limiting structure of the frame. This allows for the vertical loading of conventional cargo boxes. Figure 2 As shown;

[0029] For larger cargo containers, a frameless design can be used in the middle of the rear side between the upper cargo hold 1 and the lower cargo hold 2, such as... Figure 4 As shown, the limiting frame 7 on the upper cargo hold 1 can be pushed upwards, and the limiting frame 7 on the lower cargo hold 2 can be pushed downwards. At this time, the rear sides of the upper cargo hold 1 and the lower cargo hold 2 are open, and the two support frames 3 at the bottom of the upper cargo hold 1 can be unfolded. At this time, the upper cargo hold 1 and the lower cargo hold 2 will be connected to form a cargo compartment. The cargo box can be smoothly placed into the upper cargo hold 1 and the lower cargo hold 2 from the rear. After loading, it is as follows: Figure 3 As shown, it can deliver larger cargo boxes in a single transaction;

[0030] After the drone carrying the cargo rack flies to the target delivery area, it triggers the corresponding cargo rack throwing command according to the delivery requirements. When a larger cargo box is dropped at once, the electric push rod 6 of the lower cargo rack 2 is activated. The electric push rod 6 pushes the locking tongue 5 to separate from the slot 4 at the front end of the support frame 3. The support frame 3 rotates to the vertical position around the shaft. The larger cargo box is directly dropped downwards under the action of gravity.

[0031] When the cargo box is deployed in two stages as usual, the electric push rod 6 of the lower cargo hold 2 is activated. The electric push rod 6 pushes the locking tongue 5 to separate from the slot 4 at the front end of the support frame 3. The support frame 3 rotates around the shaft to the vertical position. The cargo box in the lower cargo hold 2 is directly released downward under the action of gravity. Then, the electric push rod 6 of the upper cargo hold 1 is activated. The electric push rod 6 pushes the locking tongue 5 to separate from the slot 4 at the front end of the support frame 3. The support frame 3 rotates around the shaft to the vertical position. The cargo box in the upper cargo hold 1 is directly released downward under the action of gravity, thus realizing the two-stage deployment of the cargo box.
