UAV remote sensing systems have become a hot topic for research in countries around the world due to their advantages such as mobility, speed and economy. They have gradually developed from research and development to the practical application stage and have become one of the main aviation remote sensing technologies in the future.

[0003] Most of the existing remote sensing and mapping UAVs have integrated, one-piece mechanical brackets. If damaged, they need to be replaced as a whole, including the casing. The replacement efficiency is low and the maintenance cost is high. At the same time, traditional airborne brackets are mostly hard-contact landing designs with poor landing cushioning, making it difficult to ensure the landing stability of remote sensing and mapping UAVs.

At the same time, traditional airborne brackets are mostly hard-contact landing designs with poor landing cushioning, making it difficult to ensure the landing stability of remote sensing and mapping UAVs.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An airborne bracket capable of improving the landing stability of a remote sensing mapping UAV comprises a connecting frame, a connecting plate fixedly connected to the bottom center of the connecting frame, a mounting groove fixedly connected to the bottom center of the connecting plate, a turbine fan connected to the internal buckle of the mounting groove, an outlet of the turbine fan connected to a three-way joint, two side output ports of the three-way joint are respectively connected to air cushions, and the inner side of the air cushion is fixedly connected to the side of the connecting frame.

[0007] Preferably, the connecting frame is buckled connected to the bottom edge of the remote sensing and mapping UAV, and card slots are equidistantly provided on the left and right sides of the bottom of the connecting frame. Card blocks are fixedly connected to the positions corresponding to the card slots on both sides of the bottom of the remote sensing and mapping UAV, and the card blocks are buckled connected to the card slots.

[0008] Preferably, a groove is provided on the surface of the mounting groove at a position corresponding to the inlet end of the three-way joint.

[0009] Preferably, there are two air cushions, which are respectively arranged on the left and right sides of the connecting frame.

[0010] Preferably, the air cushion is designed in an inverted T shape, and the air cushion consists of an outer densely woven fabric layer, a middle adhesive layer and an inner film layer.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, by adopting a connection frame and a bottom clamping design of the remote sensing mapping UAV, the onboard bracket can be independently disassembled, replaced and maintained after being damaged, without the need to carry the frame together, which can greatly improve its maintenance efficiency and reduce maintenance costs.

[0013] 2. In the utility model, by adopting the air cushion type airborne bracket design, the remote sensing and mapping UAV can make soft contact with the ground when landing, which can greatly reduce the rebound of the landing impact force, thereby improving the landing stability of the remote sensing and mapping UAV. The airborne bracket design when inflated has a small mass and can be deflated when stored, which can compress the volume of the remote sensing and mapping UAV and facilitate storage and carrying.

[0022] The invention discloses an airborne bracket capable of improving the landing stability of a remote sensing and mapping UAV, comprising a connecting frame 1 for being clamped and fixed with the remote sensing and mapping UAV so as to realize independent disassembly, maintenance and replacement, thereby improving maintenance efficiency and reducing maintenance cost. A connecting plate 2 is fixedly connected to the bottom center of the connecting frame 1, a mounting groove 3 is fixedly connected to the bottom center of the connecting plate 2, a turbo fan 4 is connected to the internal buckle of the mounting groove 3, an outlet of the turbo fan 4 is connected to a three-way joint 5, and output ports on both sides of the three-way joint 5 are respectively connected to air cushions 6. By using the turbo fan in conjunction with the three-way joint, the air cushions on both sides of the remote sensing and mapping UAV can be inflated and deployed simultaneously, thereby realizing soft contact between the remote sensing and mapping UAV and the ground when landing, effectively alleviating the impact force of the UAV landing, and improving the landing stability of the remote sensing and mapping UAV. At the same time, when the remote sensing and mapping UAV is stored, the air is deflated to compress the volume for easy storage. The inner side of the air cushion 6 is fixedly connected to the side of the connecting frame 1 to improve the stability of the air cushion structure.

[0023] In this embodiment, see Figure 5 The connecting frame 1 is snap-connected to the bottom edge of the remote sensing and mapping UAV 7. Card slots 8 are equidistantly provided on the left and right sides of the bottom of the connecting frame 1. Card blocks 9 are fixedly connected to the positions corresponding to the card slots 8 on both sides of the bottom of the remote sensing and mapping UAV 7. The card blocks 9 are snap-connected to the card slots 8, satisfying the quick-detachable card connection structure design between the connecting frame and the bottom of the remote sensing and mapping UAV.

[0024] In this embodiment, see Figure 4 A groove 10 is provided on the surface of the mounting groove 3 and at a position corresponding to the inlet end of the tee joint to meet the structural design requirements of the device.

[0025] In this embodiment, see Figure 1 The number of air cushions 6 is two, and they are respectively arranged on the left and right sides of the connection frame 1, so as to realize the full wrapping design of the bottom of the remote sensing mapping UAV.

[0026] In this embodiment, see Figure 1 , Figure 2The air cushion 6 is designed in an inverted T shape to ensure the contact area of ​​the bottom of the airborne bracket and improve the landing stability; the air cushion 6 consists of an outer densely woven cloth layer 61, which is used to prevent puncture and scratch on the outside of the air cushion; a middle adhesive layer 62, which is used to adhere and fix the inner and outer layers to ensure the stability of the air cushion structure; and an inner film layer 63, which is used to seal the inside of the air cushion to prevent air leakage and ensure the functionality of the air cushion.

[0027] Working principle of the utility model: when in use, the turbine fan 4 cooperates with the three-way connector 5 to realize synchronous inflation and expansion of the air cushions 6 on both sides of the remote sensing and mapping UAV 7, so as to realize soft contact between the remote sensing and mapping UAV 7 and the ground when landing, which can effectively alleviate the impact force of landing and ensure the stability of the landing of the remote sensing and mapping UAV;

[0028] When damaged, repaired or maintained, the connection frame 1 can be directly removed from the bottom block 9 of the remote sensing and mapping drone 7, thereby realizing independent disassembly and repair of the airborne bracket, which is efficient and low cost;

[0029] When storing, the air cushions 6 on both sides of the remote sensing and mapping drone 7 can be deflated and folded, so that the volume of the remote sensing and mapping drone 7 can be compressed, making it easy to store and carry.
