Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a heavy-duty UAV with a self-unloading function. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and onboard program control devices. With the evolution and development of UAV technology, they have been widely used in various fields such as disaster relief, geological exploration, traffic patrol, agricultural planting, military reconnaissance, and entertainment. Leveraging their high efficiency, high-altitude operation capabilities, and remote control features, UAVs provide significant technical support to various fields. Especially in post-disaster relief scenarios involving geological and weather disasters, heavy-duty UAVs, due to their material transport capabilities, have become important rescue equipment.

[0003] However, traditional heavy-duty drones still have technical limitations in practical applications: On the one hand, some models use servo motors as the action actuator to achieve cargo locking and unlocking functions. Although this method can achieve a certain degree of automated loading and unloading, the cargo load is limited and the safety and reliability are low because the load capacity of the cargo compartment depends entirely on the torque of the servo motor to overcome gravity. On the other hand, the storage box is usually fixed by bolts, which means that special tools are needed to pick up and put down the load, resulting in insufficient operation convenience and affecting the overall transportation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a heavy-duty unmanned aerial vehicle (UAV) with a self-unloading function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heavy-duty drone with self-unloading function, comprising a drone body, mounting plates symmetrically arranged under the drone body, mounting mechanisms equidistantly arranged within the mounting plates, auxiliary components arranged between the mounting mechanisms and the mounting plates, a cargo box provided by the mounting mechanisms through connecting components, and positioning components arranged on the connecting components.

[0006] Preferably, in order to facilitate assembly and subsequent self-unloading function, and to ensure stability and safety during transportation, the installation mechanism includes a slot opened in the mounting plate, an assembly slot equally spaced in the slot, an assembly plate set in the assembly slot, a cavity opened on the inner side wall of the assembly slot, a rotating plate rotatably mounted in the cavity via a rotating rod, and permanent magnets provided on the end of the rotating plate away from the assembly plate and on the inner wall of the cavity, with the two permanent magnets having the same magnetism.

[0007] Preferably, in order to ensure the positioning effect of the assembly, a rubber pad is provided at the end of the rotating plate away from the permanent magnet, and the rubber pad matches the assembly plate.

[0008] Preferably, in order to allow for insertion and positioning after assembly, and to ensure stability and firmness during transportation in conjunction with the weight of the cargo box, thus preventing slippage, the auxiliary components include limiting blocks equidistantly arranged on both sides of the assembly plate, and a limiting groove matching the limiting blocks is provided on the top of the rotating plate.

[0009] Preferably, in order to facilitate the connection and assembly of the vertical plate and the cargo box, and to facilitate subsequent disassembly, while also being compatible with the assembly and use of different cargo boxes, the connecting component includes a vertical plate that is fixedly connected to the end of the assembly plate, an insertion groove is provided at the bottom of the vertical plate, connecting blocks are equidistantly arranged on the cargo box, and an insertion plate is fixedly provided on the top of the connecting blocks, with the insertion plate interlocking with the insertion groove.

[0010] Preferably, in order to ensure a secure connection after connection and to maintain stability during transportation in conjunction with the weight of the cargo box, the positioning component includes positioning holes on the side walls of the plug plate and the vertical plate, with positioning posts installed in the positioning holes and rubber sleeves fitted at both ends of the positioning posts.

[0011] Preferably, in order to provide support for the drone body when used separately in a later stage, a bracket is fixedly installed at the bottom of the mounting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) By using the empty slot and assembly slot structure set in the mounting plate, and the rotation and engagement mechanism of the assembly plate and the rotating plate, the rapid assembly and automatic unloading of the cargo box are realized. Specifically, when the assembly plate slides into the assembly slot, it squeezes the rotating plate. The repulsive property of like poles of the permanent magnet makes the rotating plate automatically reset. With the friction enhancement effect of the rubber pad, the positioning effect of the assembly is guaranteed, and the connection stability during transportation is further enhanced by the weight of the cargo box. During the unloading stage, when the UAV descends, the cargo box contacts the ground first, and the assembly plate moves up and leaves the assembly slot. The rotating plate resets under the action of repulsive force. With the horizontal movement of the UAV, the assembly plate slides in the empty slot, and finally completes the self-unloading. This design effectively solves the problem of cumbersome assembly and unloading operations of traditional heavy-duty UAVs and improves the operation efficiency.

[0014] (2) Through the design of the limiting block and limiting groove of the auxiliary component, a plug-in limiting structure is formed after assembly. Combined with the downward pressure generated by the weight of the cargo box, the risk of the assembly plate slipping off during transportation is further avoided, ensuring transportation safety. The connecting component adopts the plug-in groove and plug-in plate plug-in method, realizing the quick connection and disassembly of the cargo box and the drone. It is compatible with cargo boxes of different sizes or types (such as cargo baskets, cargo racks, etc.), improving the equipment's adaptability to diverse transportation needs. The positioning component strengthens the connection by cooperating with the positioning column and positioning hole, combined with the anti-loosening design of the rubber sleeve, to prevent the connecting parts from accidentally falling off due to vibration during transportation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a self-unloading heavy-duty drone, including a drone body 11. This is a relatively mature technology and will not be described in detail here. An installation plate 13 is installed at the bottom of the drone body 11. Installation mechanisms are equidistantly arranged within the installation plate 13. An auxiliary component is also provided between the installation mechanisms and the installation plate 13. The installation mechanism is connected to a cargo box 12 via a connecting component. The cargo box 12 can be of various sizes and can be a cargo basket or a cargo rack, etc., to facilitate the selection of a suitable container for the items, thus facilitating the heavy-duty transportation of the drone body 11. A positioning component is also provided on the connecting component. A bracket 14 is provided at the bottom of the installation plate 13 to facilitate the overall support and lifting of the drone body 11 when not in use.

[0022] Please see Figures 1-4To facilitate the assembly and automatic unloading of the cargo box 12, the mounting mechanism includes a slot 21 formed in the mounting plate 13. Assembly slots 23 are equidistantly arranged within the slot 21, and an assembly plate 22 is disposed within each assembly slot 23. A cavity 24 is formed on the inner side wall of the assembly slot 23. A rotating plate 27 is rotatably mounted within the cavity 24 via a rotating rod 25. Permanent magnets 26 are provided at the end of the rotating plate 27 away from the assembly plate 22 and on the inner wall of the cavity 24. The two permanent magnets 26 have the same magnetic properties and repel each other. In the initial state, the rotating plate 27 is as follows: Figure 4 As shown, the permanent magnet 26 can also be replaced by an elastic component, such as a spring. Initially, the rotating plate 27 is tilted, and a rubber pad 28 is provided at the end of the rotating plate 27 away from the permanent magnet 26. The rubber pad 28 matches the assembly plate 22. When the assembly plate 22 is inserted into the assembly slot 23, the rotating plate 27 rotates under the action of the rotating rod 25. The permanent magnet 26 generates a rotational reset thrust on the rotating plate 27. The rubber pad 28 can ensure the insertion effect of the assembly plate 22. At the same time, under the action of gravity of the cargo box 12 during transportation, the disassembly effect of the assembly plate 22 is guaranteed. The auxiliary components include limiting blocks 42 equidistantly arranged on the two side walls of the assembly plate 22. The top of the rotating plate 27 is provided with a limiting groove 41 that matches the limiting block 42. This is to fix the position after assembly and prevent slippage, while not affecting subsequent unloading.

[0023] Please see Figures 1-4 To facilitate the connection and assembly of the vertical plate 32 and the cargo box 12, and to make it convenient to replace different cargo boxes 12 depending on the goods being transported, the connecting assembly includes a vertical plate 32 fixedly connected to the end of the assembly plate 22. The bottom of the vertical plate 32 has an insertion groove 34. Connecting blocks 31 are equidistantly arranged on the cargo box 12. An insertion plate 33 is fixedly arranged on the top of the connecting block 31. The insertion plate 33 is inserted into the insertion groove 34. The positioning assembly includes positioning holes 35 opened on the side walls of the insertion plate 33 and the vertical plate 32. A positioning post 36 is provided in the positioning hole 35 for insertion and positioning, preventing the insertion plate 33 from falling out of the insertion groove 34. Rubber sleeves 37 are fitted on both ends of the positioning post 36 to prevent the positioning post 36 from falling out of the positioning hole 35 without external force. At the same time, the weight of the cargo box 12 during transportation positions the positioning post 36, which also prevents it from falling out of the positioning hole 35.

[0024] Working Principle: When using this utility model, a suitable cargo box 12 is selected. The insertion plate 33 is then inserted into the insertion slot 34 for positioning. The positioning pin 36 is then inserted into the positioning hole 35, and the rubber sleeve 37 completes the positioning and fixation to prevent slippage. When connecting and assembling the cargo box 12 with the drone body 11, the assembly plate 22 slides into the empty slot 21. After being positioned above the assembly slot 23, the drone body 11 moves upward, and the assembly plate 22 enters the assembly slot 23, pressing against the rotating plate 27. With the help of the rotating rod 25, the rotating plate 27 rotates within the cavity 24. The permanent magnets 26 repel each other, causing the rotating plate 27 to rotate and reset under the repulsive force. The rubber pad 28 then positions and fixes the assembly plate 22, while the limiting block 42 enters the limiting slot. Within 41, the connection and assembly are completed. At this time, the drone body 11 takes off, carrying the cargo box 12 for transport. The weight of the cargo box 12 helps to ensure the stability and firmness of the connections, without affecting the transport operation. After arriving at the designated location, the drone body 11 descends. At this time, the cargo box 12 first contacts the ground and then continues to move downward. The assembly plate 22 moves upward and leaves the assembly slot 23, and the limiting block 42 leaves the limiting slot 41. The assembly plate 22 enters the empty slot 21, while the rotating plate 27 rotates and resets under the action of the rotating rod 25 and the repulsive force. Then, the drone body 11 moves horizontally forward or backward, carrying the mounting plate 13, while the assembly plate 22 slides relatively in the empty slot 21 to complete self-unloading. Then, the above operation is repeated for the next load transport.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
