TECHNICAL FIELD

[0001] The utility model relates to unmanned plane transportation technical field especially relates to a kind of unmanned plane bearing structure. BACKGROUND

[0002] Unmanned plane, commonly known as "unmanned aerial vehicle or" aerial unmanned plane, refers to the task-executing aircraft that can be controlled by remote control, autonomous program or artificial intelligence without human pilot on board.

[0003] In recent years, unmanned plane logistics technology iterates rapidly, and the cargo transportation system based on unmanned plane is improving day by day. The current mainstream unmanned plane cargo carrying mode mainly includes two types: one is to fix the cargo by using a binding belt, and the other is to use a special fixing platform. The former lacks rigid support structure, and the cargo is easily displaced and shaken due to air flow disturbance, unmanned plane attitude adjustment or mechanical jolt during flight. This not only breaks the flight balance of the unmanned plane and reduces the flight stability, but also greatly reduces the operation efficiency of multi-batch cargo transportation. The latter can effectively ensure the transportation stability, but the fixing platform and the unmanned plane are usually designed in an integrated manner, and the disassembly process is complicated. Considering that the unmanned plane needs to be regularly maintained and repaired, the existence of the fixing platform often interferes with the maintenance work and affects the equipment maintenance efficiency. SUMMARY

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a UAV support structure, including a first support plate and a second support plate, which are slidably connected. A quick-fixing mechanism is provided at the outer corners of both the first and second support plates. Each quick-fixing mechanism includes a connecting shell, and a connecting frame is fixedly connected to the outer wall of the connecting shell. The connecting frame is fixedly connected to the first and second support plates by bolts. Four spaced sliding plates are slidably connected inside the connecting shell. A fixed plate is fixedly connected to one end of each sliding plate that is close to the other, and a sliding pin is fixedly connected to one end of each sliding plate that is far from the other. A rotating disk is rotatably connected to the outer end of the connecting shell. Each rotating disk has a guide groove corresponding to a sliding pin, and the sliding pin is slidably connected inside the corresponding guide groove. The side of the connecting shell is fixedly... The device is fixedly connected to an adjustment box, which contains a drive mechanism that is connected to the rotating disk. The first and second support plates can be fitted with cargo baskets or boxes. The lower part of the drone's legs is often cylindrical, allowing the quick-fixing mechanisms at all four ends of the device to cooperate with the drone's legs. The drive mechanism drives the rotating disk to rotate. When the rotating disk rotates, it presses against the sliding pin through a guide groove, causing the sliding pin to move the sliding plate. As the sliding plate moves, it brings the fixing plate closer to the drone's legs, achieving the function of pressing and fixing it to the drone's legs. Removal is achieved by rotating the rotating disk in the opposite direction, thus canceling the fixing effect and allowing for removal. Installation and disassembly are simple and quick. During maintenance and repair, the first and second support plates can be quickly disassembled and installed without affecting the maintenance of the transport drone.

[0006] In a preferred embodiment, a worm gear is rotatably connected inside the adjustment box, and a worm rack is fixedly connected to the rotating disk at the corresponding position of the worm gear. The worm gear and the worm rack are meshed and connected for transmission. The worm gear and the worm rack have self-locking properties and strong load-bearing capacity, which makes the rotation drive of the rotating disk more stable and the adjustment easier and more convenient.

[0007] In a preferred embodiment, a torsion handle is fixedly connected to the end of the worm gear, which can drive the worm gear to rotate.

[0008] In a preferred embodiment, the outer periphery of the torsion handle is provided with uniformly distributed grooves, which can improve the contact friction of the torsion handle and facilitate the rotational drive of the torsion handle.

[0009] In a preferred embodiment, the mounting plates are provided with friction textures on their adjacent end faces to increase the friction between the mounting plates and the drone legs, making the fixed installation more stable.

[0010] In a preferred embodiment, a guide plate is fixedly connected to one end of the first support plate near the second support plate. The guide plate is slidably connected to the second support plate. By setting the guide plate, the first support plate and the second support plate can be separated, which facilitates the installation operation and reduces the installation difficulty.

[0011] In a preferred embodiment, the second support plate is fixedly connected to symmetrically distributed guide handles on both sides near the end of the first support plate. The front end of each guide handle is provided with an anti-detachment handle. The guide handle is slidably connected inside the first support plate, and the guide handle can prevent the first support plate and the second support plate from detaching from each other.

[0012] As a preferred embodiment, the fixing plate is an arc-shaped plate, which can fit more stably with the drone's legs.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This invention allows four fixing plates to be brought close to the drone's legs by rotating the torsion handle and then pressed and fixed, achieving the function of pressing and fixing them to the drone's legs. To remove them, the fixing effect can be canceled by rotating the rotating disk in the opposite direction, allowing for removal. The installation and disassembly operations are simple and quick. During maintenance and repair, the first and second bearing plates can be quickly disassembled and installed without affecting the maintenance of the transport drone due to their presence. After maintenance, they can also be quickly reinstalled, resulting in higher connection and installation efficiency. Attached Figure Description

A quick-fixing mechanism is provided at the outer corners of both the first and second support plates 1 and 2. The quick-fixing mechanism includes a connecting shell 3, with a connecting frame 4 fixedly connected to the outer wall of the connecting shell 3. The connecting frame 4 is fixedly connected to the first and second support plates 1 and 2 by bolts. Four spaced sliding plates 12 are slidably connected inside the connecting shell 3. A fixed plate 11 is fixedly connected to one end of each sliding plate 12 that is close to each other, and a sliding pin 10 is fixedly connected to one end of each sliding plate 12 that is far apart from each other. A rotating disk 6 is rotatably connected to the outer end of the connecting shell 3. Each rotating disk 6 has a guide groove 9 corresponding to a sliding pin 10, and the sliding pin 10 is slidably connected inside its corresponding guide groove 9. An adjustment box 7 is fixedly connected to the side of the connecting shell 3 for adjustment. The box 7 is equipped with a drive mechanism that is connected to the rotating disk 6. The first support plate 1 and the second support plate 2 can be used to install transport baskets or transport boxes for the goods. The lower part of the drone legs is usually cylindrical. The quick fixing mechanism at the four ends of the device can cooperate with the drone legs. The drive mechanism drives the rotating disk 6 to rotate. When the rotating disk 6 rotates, it presses the sliding pin 10 through the guide groove 9, so that the sliding pin 10 drives the sliding plate 12 to move. When the sliding plate 12 moves, it can bring the fixing plate 11 close to the drone legs, realizing the function of pressing and fixing it to the drone legs. When removing, the fixing effect can be canceled by rotating the rotating disk 6 in the opposite direction, and it can be removed. The installation and disassembly operation is simple and quick. During maintenance and repair, the first support plate 1 and the second support plate 2 can be quickly disassembled and installed without affecting the maintenance of the transport drone due to the presence of the first support plate 1 and the second support plate 2.

[0024] like Figures 1-5As shown, a worm gear 13 is rotatably connected inside the adjustment box 7, and a worm rack 14 is fixedly connected to the rotating disk 6 at the corresponding position of the worm gear 13. The worm gear 13 and the worm rack 14 are meshed and connected for transmission. The worm gear 13 and the worm rack 14 have self-locking properties and strong load-bearing capacity, which makes the rotation drive of the rotating disk 6 more stable and the adjustment easier and more convenient.

[0025] like Figures 1-5 As shown, a torsion handle 8 is fixedly connected to the end of the worm gear 13, which can drive the worm gear 13 to rotate.

[0026] like Figures 1-5 As shown, the outer periphery of the torsion handle 8 is provided with uniformly distributed grooves, which can improve the contact friction of the torsion handle 8 and facilitate the rotation drive of the torsion handle 8.

[0027] like Figures 1-5 As shown, the mounting plates 11 have friction textures on their close-to-each end faces to increase the friction between the mounting plates 11 and the drone legs, making the fixed installation more stable.

[0028] like Figures 1-5 As shown, a guide plate 15 is fixedly connected to one end of the first bearing plate 1 near the second bearing plate 2. The guide plate 15 is slidably connected to the second bearing plate (2). By setting the guide plate 15, the first bearing plate 1 and the second bearing plate 2 can be separated, which facilitates the installation operation and reduces the installation difficulty.

[0029] like Figures 1-5 As shown, the second support plate 2 is fixedly connected to both sides of the end near the first support plate 1 with symmetrically distributed guide handles 5. The front end of the guide handle 5 is provided with an anti-detachment handle. The guide handle 5 is slidably connected inside the first support plate 1. The guide handle 5 can prevent the first support plate 1 and the second support plate 2 from detaching from each other.

[0030] like Figures 1-5 As shown, the fixing plate 11 is an arc-shaped plate, which can fit more stably with the drone's legs.

[0031] Working principle: During installation, the first support plate 1 and the second support plate 2 are slidably separated, so that the quick-fixing mechanisms set at the four corners correspond to the drone legs. Then, the first support plate 1 and the second support plate 2 are closed, allowing the drone legs to pass through the quick-fixing mechanisms. Then, the torsion handle 8 is rotated to drive the worm gear 13 to rotate. The rotation of the worm gear 13, in conjunction with the worm rack 14, drives the rotating disk 6 to rotate. When the rotating disk 6 rotates, it presses the sliding pin 10 through the guide groove 9, causing the sliding pin 10 to drive the sliding plate 12 to move. When the sliding plate 12 moves, it can bring the fixing plate 11 closer to the drone legs, realizing the function of pressing and fixing it to the drone legs. When removing, the fixing effect can be canceled by rotating the rotating disk 6 in the opposite direction, and the removal can be carried out. The installation and disassembly operation is simple and quick. During maintenance and repair, the first support plate 1 and the second support plate 2 can be quickly disassembled and installed without affecting the maintenance of the transport drone due to the presence of the first support plate 1 and the second support plate 2.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
