Description

Technical Field

[0001] This application relates to the field of cargo containers, and more particularly to a cargo container for use in a heavy-load eVTOL aircraft. Background Technology

[0002] Heavy-load eVTOL aircraft refer to aircraft that employ electric vertical takeoff and landing technology and possess a large payload capacity, primarily used in emergency rescue, logistics transportation, and other scenarios. Their core features include vertical takeoff and landing capability, adaptability to short-distance takeoff and landing sites, and high-efficiency flight performance. Heavy-load eVTOL aircraft often utilize cargo containers for material transport. These cargo containers are specialized containers used for transporting or carrying goods, primarily for low-altitude flight equipment such as drones and multi-rotor aircraft. Made of carbon fiber, they possess high strength, lightweight (weighing only 1 / 3 of traditional metal containers), and corrosion resistance. The interior is equipped with high-density sponge or special foam cushioning material, which can completely enclose the aircraft and protect critical components. In conventional cargo container use, the container is installed at the bottom of the aircraft, the materials to be transported are placed inside, and a cover is installed on the top of the container for easy concealment.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional aircraft cargo containers are usually suspended by ropes during transportation. However, when the cargo containers are placed, they are prone to tilting due to the instability of the aircraft and the influence of external wind, which can lead to a corner of the cargo container colliding with the ground and causing damage to that corner.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issue of collisions that can easily occur during unloading of conventional aircraft cargo containers, this application provides a cargo container for heavy-duty eVTOL aircraft.

[0006] This application provides a cargo box for a heavy-load eVTOL aircraft, employing the following technical solution: A cargo box for a heavy-duty eVTOL aircraft includes a box body and a fixing rope. A cover is rotatably mounted on the top of the box body, and the dimensions of the bottom of the cover are adapted to the dimensions of the top of the box body. Two pulleys are slidably connected to the surface of the fixing rope. A rotating rod is fixedly mounted on one end of each pulley. A mounting bracket is rotatably connected to the surface of each pulley. The two rotating rods are symmetrically distributed about the mounting bracket. The bottom end of the fixing rope is fixedly mounted to the top of the cover. The two fixing ropes are symmetrically distributed about the cover. The center of the rotating rod and the center of the pulley are on the same straight line.

[0007] Preferably, a motor is fixedly connected to the bottom end of the mounting bracket, a rotating shaft is fixedly mounted to one end of the motor, and a synchronous belt is driven to the surface of the rotating shaft.

[0008] Preferably, the surface of the rotating shaft is provided with a plurality of auxiliary grooves, and the plurality of auxiliary grooves are arranged in a circular array with the center of the rotating shaft as the axis.

[0009] Preferably, two limiting wheels are rotatably mounted on the inner wall of the mounting bracket, and the surface of the limiting wheels is connected to the surface of the rotating shaft.

[0010] Preferably, a fixing frame is fixedly installed at the bottom end of the fixing rope, a connecting block is slidably connected to the inner wall of the fixing frame, the bottom end of the connecting block is fixedly connected to the top of the cover, a fixing bolt is snapped into the inner wall of the fixing frame, and the surface of the fixing bolt is threaded onto the inner wall of the connecting block.

[0011] Preferably, a level sensor is fixedly connected to the top of the shielding cover, and one end of the level sensor is electrically connected to one end of the motor.

[0012] Preferably, a plurality of Velcro straps are fixedly installed on the surface of the box, and a cover frame is movably connected to the surface of the Velcro straps. The cover frame is a sponge pad, and the dimensions of the inner wall of the cover frame are adapted to the dimensions of the bottom of the box.

[0013] In summary, this application includes the following beneficial technical effects: 1. By installing a fixing rope on top of the cover, with pulleys slidably connected to the surface of the fixing rope, and several pulleys connected by a rotating rod, a mounting frame is rotatably mounted on one end of each pulley. This allows for control of the length of the fixing rope at both ends, thereby controlling the angle adjustment between the container and the cover to ensure a smooth landing during unloading. A motor is mounted at the bottom of the mounting frame, and a rotating shaft is mounted at the output end of the motor. A synchronous belt is connected to the surface of the rotating shaft, allowing the synchronous belt to rotate after the motor starts, thus rotating the pulleys at both ends of the rotating rod. Several auxiliary grooves are formed on the surface of the rotating shaft to prevent slippage between the synchronous belt and the rotating shaft. A limit wheel is rotatably connected to the inner wall of the mounting frame to limit the fixing rope and facilitate pulley control of the limit wheel's movement. Compared to existing technologies, this method effectively improves the stability of the cargo box during landing. 2. A fixing frame can also be installed at one end of the fixing rope. The inner wall of the fixing frame is equipped with connecting blocks by fixing bolts, so that the fixing rope can be installed and removed after the fixing bolts are removed. A level sensor is installed on the top of the cover to detect the levelness of the cover. Several Velcro straps are installed at the bottom of the box, and sponge material covering frames are glued to the surface of the Velcro straps to cover the bottom of the box and prevent the bottom of the box from being hit. This effectively improves the use effect of the device. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0017] This application discloses a cargo box for a heavy-load eVTOL aircraft, referring to... Figure 1 - Figure 2The system includes a container 1. In use, the container 1 is installed at the bottom of the aircraft, and the materials to be transported are placed inside the container 1. A cover 2 is installed on the top of the container 1 to cover the top of the container 1. A fixing rope 3 is installed on the top of the cover 2. A pulley 4 is slidably connected to the surface of the fixing rope 3. Several pulleys 4 are connected to each other by a rotating rod 5. A mounting frame 6 is rotatably installed at one end of the pulley 4. The mounting frame 6 is installed at the bottom of the aircraft. The length of the two ends of the fixing rope 3 is controlled by the pulleys 4, thereby controlling the angle adjustment between the container 1 and the cover 2 to ensure a smooth landing during unloading and effectively improve the stability of the cargo container when landing.

[0018] Reference Figure 2 A motor 7 is installed at the bottom of the mounting frame 6, and a rotating shaft 9 is installed at the output end of the motor 7. A synchronous belt 8 is connected to the surface of the rotating shaft 9. After the motor 7 is started, it controls the synchronous belt 8 to drive the rotating shaft 9 to rotate, which in turn drives the pulleys 4 at both ends of the rotating rod 5 to rotate, thereby controlling the adjustment of the pull rope. This makes it more convenient to use. Several auxiliary grooves 10 are opened on the surface of the rotating shaft 9. The auxiliary grooves 10 increase the friction between the rotating shaft 9 and the synchronous belt 8, thereby preventing slippage between the synchronous belt 8 and the rotating shaft 9. A limit wheel 11 is rotatably connected to the inner wall of the mounting frame 6. The surface of the limit wheel 11 is slidably installed on the surface of the fixed rope 3. The limit wheel 11 limits the fixed rope 3, making it convenient for the pulley 4 to control the movement of the limit wheel 11, thereby improving the control effect of the fixed rope 3.

[0019] Reference Figure 2 - Figure 4 A fixing frame 12 is installed at one end of the fixing rope 3. A connecting block 13 is slidably connected to the inner wall of the fixing frame 12, and a fixing bolt 14 is snapped into the inner wall of the fixing frame 12. The surface of the fixing bolt 14 is threadedly connected to the inside of the connecting block 13. The bottom end of the connecting block 13 is fixedly installed to the top of the cover 2. The fixing frame 12 and the connecting block 13 are connected by the fixing bolt 14, which facilitates the installation and removal of the fixing rope 3. A level sensor 15 is installed on the top of the cover 2. One end of the level sensor 15 is connected to one end of the motor 7. The level sensor 15 detects the levelness of the cover 2 and controls the motor 7 to adjust it, thereby automatically adjusting the angle of the cover 2, which is more convenient to use. Several Velcro straps 17 are installed at the bottom of the box 1. A sponge cover frame 16 is glued to the surface of the Velcro straps 17. The Velcro straps 17 facilitate the installation and removal of the cover frame 16. The cover frame 16 covers the bottom of the box 1 to prevent the bottom of the box 1 from being hit.

[0020] The implementation principle of a cargo box for a heavy-duty eVTOL aircraft according to an embodiment of this application is as follows: A fixing rope 3 is installed on the top of a cover 2. A pulley 4 is slidably connected to the surface of the fixing rope 3. Several pulleys 4 are connected by a rotating rod 5. A mounting frame 6 is rotatably mounted on one end of each pulley 4 to facilitate mounting the mounting frame 6 on the bottom of the aircraft. The length of both ends of the fixing rope 3 is controlled by the pulleys 4, thereby controlling the angle adjustment between the cargo box 1 and the cover 2 to ensure a smooth landing during unloading. A motor 7 is installed at the bottom of the mounting frame 6, and a rotating shaft 9 is installed at the output end of the motor 7. A synchronous belt 8 is connected to the surface of the rotating shaft 9 to facilitate... After the auxiliary motor 7 starts, it controls the synchronous belt 8 to drive the rotating shaft 9 to rotate, which in turn drives the pulleys 4 at both ends of the rotating rod 5 to rotate, thereby controlling the adjustment of the pull rope. This makes it more convenient to use. Several auxiliary grooves 10 are opened on the surface of the rotating shaft 9 to increase the friction between the rotating shaft 9 and the synchronous belt 8, thereby preventing slippage between the synchronous belt 8 and the rotating shaft 9. The inner wall of the mounting bracket 6 is rotatably connected to the limiting wheel 11. The surface of the limiting wheel 11 is slidably installed on the surface of the fixed rope 3, so that the fixed rope 3 can be limited by the limiting wheel 11. This makes it convenient for the pulley 4 to control the movement of the limiting wheel 11, thereby improving the control effect on the fixed rope 3.

[0021] A fixing frame 12 can also be installed at one end of the fixing rope 3. A connecting block 13 is slidably connected to the inner wall of the fixing frame 12, and a fixing bolt 14 is snapped into the inner wall of the fixing frame 12. The surface of the fixing bolt 14 is threadedly connected to the inside of the connecting block 13. The bottom end of the connecting block 13 is fixedly installed to the top of the cover 2, so that the fixing frame 12 and the connecting block 13 can be connected by the fixing bolt 14, thereby facilitating the installation and removal of the fixing rope 3. A level sensor 15 is installed on the top of the cover 2. One end of the level sensor 15 is connected to one end of the motor 7, so that the level of the cover 2 can be detected by the level sensor 15 and the motor 7 can be controlled to adjust, thereby automatically adjusting the angle of the cover 2, which is more convenient to use. Several Velcro straps 17 are installed at the bottom of the box 1. A sponge cover frame 16 is glued to the surface of the Velcro straps 17. The Velcro straps 17 facilitate the installation and removal of the cover frame 16, so that the bottom of the box 1 can be covered by the cover frame 16 to prevent the bottom of the box 1 from being hit.

[0022] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
