However, due to their amphibious characteristics, the UAVs have a low fuselage and a smooth lower surface.

[0003] In the daily inspection and maintenance of drones, it is usually necessary to lift the drone off the ground. In the past, because the belly of such amphibious drones was at a low height from the ground, the drone was mainly hoisted and then placed on the bracket. However, the hoisting required a high site, time and cost, which made it extremely inconvenient to use.

[0004] In order to improve the convenience of inspection and maintenance of such low-altitude amphibious UAVs and reduce their use costs, an adjustable lightweight fuselage bracket that can adapt to low-altitude UAVs is designed. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the utility model provides an adjustable lightweight fuselage bracket that can adapt to low-altitude drones, solving the problems of the prior art such as complex device, difficult operation, great safety hazards and high maintenance costs.

[0007] A low-height fuselage bracket for an amphibious unmanned aerial vehicle comprises a supporting device and a lifting device, the two parts being disassembled and assembled; the supporting device being liftable, with the lowest height being lower than the distance between the bottom of the unmanned aerial vehicle and the ground; the lifting device being supportable and stowable, and being able to achieve support at different angles.

[0008] The support device consists of a support body, a support foam, a support plate, a connecting hinge, an adjustable bracket and a telescopic screw; the support foam is fastened and adhered to the upper surface of the support plate; the support plate is connected to the support body through the connecting hinge; and the telescopic screw is embedded in the support body.

[0009] The supporting body is provided with a groove, and the length, width and height of the adjustable bracket are all smaller than the groove, and can be completely embedded in the groove after being laid flat.

[0010] After the jacking device is connected to the supporting device, the jacking device can drive the supporting device to rise and fall.

[0011] As a preferred technical solution, the supporting device and the lifting device are connected via a mortise and tenon structure.

[0012] As a preferred technical solution, the supporting foam is made of rough polyurethane foam.

[0013] As a preferred technical solution, the lifting device is a scissors-difference lifting device.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0038] like Figure 2 As shown, the support device 1 is composed of a support body 3, a support foam 4, a support plate 5, a connecting hinge 6, an adjustable bracket 7 and a telescopic screw 8.

[0039] The supporting foam 4 is fastened and adhered to the upper surface of the supporting plate 5 ; the supporting plate 5 is connected to the supporting body 3 via a connecting hinge 6 ; and the telescopic lead screw 8 is embedded in the supporting body 3 .

[0040] like Figure 3 As shown, a first rotating shaft hole 9 is provided at the bottom of the support plate 5, a second rotating shaft hole 10 is provided at the embedded end of the telescopic screw 8, and a third rotating shaft hole 11 and a fourth rotating shaft hole 12 are provided at both ends of the adjustable bracket 7, which are connected to the first rotating shaft hole 9 and the second rotating shaft hole 10 through a first rotating pin 13 and a second rotating pin 14 respectively.

[0041] The adjustable bracket 7 can be adjusted and changed along with the telescopic screw 8 to change the support angle, so that the support plate 5 forms different angles to adapt to the bottom surface of the drone.

[0042] c) Lifting device 2

[0043] The lifting device uses two mature mechanical lifting devices commonly used in the market and is symmetrically installed below the supporting body 3.

[0044] (II) Working process:

[0045] When you need to lift the drone, follow these steps:

[0046] 1) Step 1: Assemble the jacking device 1 and the supporting device 2 in the stowed state into a fuselage bracket, such as Figure 4 and Figure 5 As shown;

[0047] 2) Step 2: Place the assembled fuselage bracket on one side of the drone and move the bracket horizontally to the bottom of the drone. Figure 6 and Figure 7 As shown;

[0048] 3) Step 3: Adjust the telescopic screws 8 on both sides to make the left and right support plates 5 and the support foam 4 basically consistent with the cross-sectional angle of the bottom of the fuselage, such as Figure 8 and Fig. 9 As shown;

[0049] 4) Step 4: Adjust the lifting device 2 to raise the height of the fuselage bracket, and at the same time adjust the telescopic screw 8 to make the support foam 4 on the left and right support plates 5 fit the bottom section of the fuselage completely; continue to raise the lifting device 2 to make the drone completely off the ground, such as Fig.10 shown.

[0050] The low-height fuselage bracket of the amphibious UAV includes a supporting device 1 and a lifting device 2, and the two parts are connected by a mortise and tenon structure and can be disassembled; the supporting device 2 can be raised and lowered, and the lowest height is lower than the distance between the bottom of the UAV and the ground; the lifting device can support and be stored, and can achieve support at different angles.

[0051] The support device 2 is composed of a support body 3, a support foam 4, a support plate 5, a connecting hinge 6, an adjustable bracket 7 and a telescopic screw 8; the support foam 4 is fastened and adhered to the upper surface of the support plate 5; the support plate 5 is connected to the support body 3 through the connecting hinge 6; the telescopic screw 8 is embedded in the support body 3.

[0052] Preferably, the supporting foam 4 is made of rough polyurethane foam.

[0053] The support body 3 is provided with a groove, and the length, width and height of the adjustable bracket are all smaller than the groove, and can be completely embedded in the groove after being laid flat.

[0054] After the lifting device 2 is connected to the supporting device 1 , the lifting device 2 can drive the supporting device 1 to rise and fall.

[0055] Preferably, the lifting device 2 is a scissors-difference lifting device.

[0056] In order to avoid the need for external mechanical lifting equipment when lifting the UAV, which is limited by site, timing and cost, and to reduce the difficulty of operation and labor intensity, the utility model designs an adjustable lightweight fuselage bracket that can adapt to low-altitude UAVs.

[0057] The traditional method is that the bracket surface is consistent with the shape of the bottom of the drone and is fixed, resulting in the overall height of the bracket being relatively high and unable to enter the bottom of the belly of the drone.

[0058] The utility model reduces the overall height of the bracket when entering the bottom of the belly of the machine through the design of the support plate with adjustable angle, thereby improving the convenience of use and maintenance. The scheme has a simple and reliable structure, low manufacturing cost, low technical requirements for users, and strong versatility.
