Description

Technical Field

[0001] This utility model relates to the technical field of heavy-load unmanned aerial vehicle (UAV) equipment, specifically to a large-payload UAV. Background Technology

[0002] A heavy-duty unmanned aerial vehicle (UAV) is an unmanned aerial vehicle with specific payload transport capabilities. Equipped with a high-performance power system, precise navigation module, and payload capacity, it can safely carry goods, equipment, and other materials to complete aerial transport missions along pre-set routes or under remote control. Its core function is to overcome the geographical and scenario constraints of ground transportation, and it is widely used in logistics distribution, emergency disaster relief, agricultural operations, and industrial settings, significantly improving the efficiency of material transportation and reducing labor costs and operational risks. For example, a large-payload drone disclosed in Chinese patent literature (publication number: CN222973620U) uses two clamps to hold and limit the cargo in the carrier box, preventing the cargo from swaying and shifting inside the carrier box during the drone's flight. This ensures the stability and safety of the drone during transport and solves the problem that some existing drones use ropes and hooks to lift cargo, which can cause the cargo to sway due to wind during flight, affecting the drone's stability and posing certain safety hazards, thus reducing its practicality.

[0003] However, the equipment only uses a carrier box and clamps to fix the goods, without any loading and unloading auxiliary structures. When dealing with heavy goods in heavy load scenarios, it is necessary to rely entirely on manual handling to move them into the carrier box. This not only results in high operational intensity and low efficiency, but also easily leads to personnel injury or goods collision due to improper handling. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large-payload unmanned aerial vehicle (UAV), comprising: a UAV body, a payload bay frame fixedly connected to the bottom of the UAV body, a baffle fixedly connected to one side of the payload bay frame, a cylinder cover fixedly connected to one outer end of the baffle, a protective drive box fixedly connected to the lower end of one side of the payload bay frame, a feeding / discharging mechanism provided inside the protective drive box and on the lower inner side of the payload bay frame, a limiting mechanism provided on the inner side of the baffle, and a support mechanism provided at one bottom end of the payload bay frame.

[0006] As a further embodiment of this utility model: the feeding and discharging mechanism includes a material receiving roller, a gear, and a toothed belt.

A toothed belt is provided between every two sets of gears. The drive gear meshes with a toothed ring, and the toothed ring is located at the shaft end of the first set of material-bearing rollers.

[0008] As a further embodiment of this utility model: the limiting mechanism includes a cylinder, a connecting plate and an inflatable clamping pad. The cylinder is fixedly connected inside the cylinder cover and extends through the baffle into the load-bearing frame. The connecting plate is fixedly connected to the movable end of the cylinder.

[0018] Reference Figures 1 to 6 In this embodiment of the utility model, a large-payload unmanned aerial vehicle (UAV) includes: a UAV body 1, the core body of the UAV, which provides the power, navigation and control functions required for flight, and is the foundation for bearing all subsequent load structures, ensuring the overall flight stability of the UAV and the execution of transportation tasks. A load-bearing frame 2 is fixedly connected to the bottom of the UAV body 1, serving as the core framework for cargo storage. A baffle 3 is fixedly connected to one side of the load-bearing frame 2 to form protection for cargo storage.

[0019] A cylinder cover 4 is fixedly connected to one side of the baffle 3 for protection. A protective drive box 5 is fixedly connected to the lower side of one side of the load-bearing frame 2 for protecting the drive components. The inside of the protective drive box 5 and the lower inside of the load-bearing frame 2 are equipped with a feeding and discharging mechanism 6. A limiting mechanism 7 is provided on the inside of the baffle 3. A support mechanism 8 is provided at one bottom end of the load-bearing frame 2. The other side and the back of the load-bearing frame 2 are also fixedly connected with the baffle 3 structure. There are four sets of cylinder covers 4, two sets of limiting mechanisms 7, and multiple sets of support mechanisms 8, which are symmetrically arranged at the bottom of the load-bearing frame 2.

[0020] Reference Figure 2 and Figure 4The feeding and discharging mechanism 6 includes a material receiving roller 61, a gear 62 and a toothed belt 63. The material receiving roller 61 is rotatably connected to one end of the inner side of the load-bearing frame 2, and the shaft end of the material receiving roller 61 extends to the outside of the load-bearing frame 2. The gear 62 is fixedly connected to the shaft end of the material receiving roller 61 that extends to the outside of the load-bearing frame 2. The toothed belt 63 is located on the outside of the gear 62. The motor 64, drive gear 65, and gear ring 66 are fixedly connected to one end of the protective drive box 5, the drive gear 65 is fixedly connected to the output end of the motor 64, and the gear ring 66 is fixedly connected to the shaft end of the material receiving roller 61. Multiple sets of material-bearing rollers 61 are arranged horizontally and symmetrically below the inner side of the load-bearing frame 2. Each of the first and last sets of material-bearing rollers 61 has a set of gears 62 at its shaft end, while the remaining material-bearing rollers 61 each have two sets of gears 62 at their shaft ends. A toothed belt 63 is provided between every two sets of gears 62. A drive gear 65 meshes with a toothed ring 66, which is located at the shaft end of the first set of material-bearing rollers 61. The drive gear 65 is driven to rotate via the output of a motor 64, and the drive gear 65 rotates through its meshing with the toothed ring 66. The first set of material-bearing rollers 61 rotates; the gear 62 at the shaft end of the first set of material-bearing rollers 61 drives the other material-bearing rollers 61 to rotate synchronously through the toothed belt 63. The rotation of multiple sets of material-bearing rollers 61 forms the conveying power, which transports the goods from inside the load-bearing frame 2 inward, realizing efficient loading. Unloading can be done by reversing the operation. In this way, when dealing with heavy goods, the labor cost and operation intensity are greatly reduced, and personnel injuries or goods collisions that may occur during the handling process are avoided. At the same time, the operation difficulty is reduced and the loading and unloading efficiency is improved, thereby improving the turnover efficiency of the drone.

[0021] Reference Figure 2 and Figure 5 The limiting mechanism 7 includes a cylinder 71, a connecting plate 72, and inflatable clamping pads 73. The cylinder 71 is fixedly connected inside the cylinder cover 4 and extends through the baffle 3 into the load-bearing frame 2. The connecting plate 72 is fixedly connected to the movable end of the cylinder 71. Multiple sets of inflatable clamping pads 73 are symmetrically fixedly connected to one side of the connecting plate 72. The movable end of the cylinder 71 pushes the connecting plate 72 to move towards the cargo inside the load-bearing frame 2 until the multiple sets of inflatable clamping pads 73 on one side of the connecting plate 72 are tightly attached to the surface of the cargo. The flexible clamping force of the inflatable clamping pads 73 limits and fixes the cargo, preventing the cargo from shifting due to bumps during transportation and avoiding squeezing damage to the cargo caused by rigid clamping. It can also adapt to cargo of different sizes and shapes.

[0022] Reference Figure 1 and Figure 6 The support mechanism 8 includes an internal threaded sleeve 81 and a threaded rod 82. The internal threaded sleeve 81 is fixedly connected to one end of the bottom of the load cell frame 2, and the threaded rod 82 is threadedly connected to the inside of the internal threaded sleeve 81. The multi-sided rotating block 83 and the rubber foot pad 84 are fixedly connected to the lower outer side of the threaded rod 82. The multi-sided rotating block 83 is fixedly connected to the bottom of the threaded rod 82. By rotating the multi-sided rotating block 83 in the support mechanism 8, the threaded rod 82 is screwed into the inner threaded sleeve 81, so that the rubber foot pad 84 contacts the ground and supports the load-bearing frame 2, ensuring the stability of the UAV when it is parked. By rotating the multi-sided rotating block 83 in the opposite direction, the threaded rod 82 is disengaged from the inner threaded sleeve 81, so that the rubber foot pad 84 can be replaced, reducing maintenance costs and downtime.

[0023] Reference Figure 1 and Figure 3 The front of the load-bearing frame 2 is provided with a door panel 9 via a hinge, which serves as a cargo entrance and exit when opened. A threaded locking rod 10 is provided at one end of the outer side of the door panel 9. One end of the threaded locking rod 10 passes through the door panel 9 and is threadedly connected to the load-bearing frame 2. The position of the door panel 9 is locked by the threaded locking rod 10, completing the initial fixation of the cargo. The other end of the threaded locking rod 10 is fixedly connected to a handle 11, which allows for easy manual rotation of the threaded locking rod 10. Multiple sets of threaded locking rods 10 and handles 11 are provided.

[0024] The working principle of this utility model is as follows: When carrying out cargo transportation operations, firstly, by rotating the handle 11, the threaded locking rod 10 is rotated, causing the threaded locking rod 10 to disengage from the load-bearing frame 2. Then, the door panel 9 is opened around the hinge, which opens the cargo entrance of the load-bearing frame 2. The cargo to be transported is placed on the multiple sets of material-bearing rollers 61 on the lower inner side of the load-bearing frame 2. Then, the motor 64 inside the protective drive box 5 is started. The output end of the motor 64 drives the drive gear 65 to rotate. The drive gear 65, through meshing with the gear ring 66, drives the first set of material-bearing rollers 61 to rotate. The teeth at the shaft end of the first set of material-bearing rollers 61... Wheel 62 drives the remaining material-bearing rollers 61 to rotate synchronously through toothed belt 63. The rotation of multiple sets of material-bearing rollers 61 forms the conveying power, which transports the goods from inside the load-bearing frame 2 to the inside, achieving efficient loading. Unloading can be done by reversing the operation. In this way, when dealing with heavy goods, labor costs and operational intensity are greatly reduced, and personnel injuries or goods collisions may occur during the handling process. At the same time, the operation difficulty is reduced and the loading and unloading efficiency is improved, as well as the turnover efficiency of the drone. Then, the door panel 9 is closed and the handle 11 is rotated in the opposite direction. The door panel 9 is locked to the load-bearing frame 2 through the threaded locking rod 10, completing the initial fixation of the goods. Next, the cylinder 71 inside the cylinder cover 4 is activated. The movable end of the cylinder 71 pushes the connecting plate 72 to move towards the cargo inside the load-bearing frame 2 until the multiple sets of inflatable clamping pads 73 on one side of the connecting plate 72 are tightly attached to the surface of the cargo. The cargo is limited and fixed by the flexible clamping force of the inflatable clamping pads 73, which prevents the cargo from shifting due to bumps during transportation and avoids squeezing damage to the cargo caused by rigid clamping. It can also adapt to cargo of different sizes and shapes, and the fixing range is flexible and adjustable, with strong versatility. Before the drone takes off, the moving threaded rod 82 is screwed into the inner threaded sleeve 81 by rotating the polygonal rotating block 83 in the support mechanism 8, so that the rubber foot pad 84 contacts the ground and supports the load-bearing frame 2, ensuring the stability of the drone when it is parked. By rotating the polygonal rotating block 83 in the opposite direction, the threaded rod 82 is disengaged from the inner threaded sleeve 81, thus avoiding the need to replace the rubber foot pad 84, reducing maintenance costs and downtime, and ensuring the continuous operation capability of the equipment.
