[0025] Embodiment 1

[0026] like Figures 1 to 3 The first embodiment of the UAV mounting structure of the utility model is shown, which provides a UAV mounting structure, including a connecting rod 1, a main rod 2, a secondary rod 3 and a fixing rod 6 for fixing cargo, wherein one end of the connecting rod 1 is connected to the UAV, and the other end is connected to the main rod 2, the main rod 2 and the secondary rod 3 are connected with a first rotating device 4, a second rotating motor 21 is connected between the first rotating device 4 and the main rod 2, the rotation axis of the first rotating device 4 intersects with the rotation axis of the second rotating motor 21, and the secondary rod 3 is connected to the fixing rod 6.

[0027] The UAV mounting structure of the utility model is installed on the UAV through a connecting rod 1, and the cargo is fixed on the fixed rod 6. The first rotating device 4 drives the sub-rod 3 to rotate, changing the position of the fixed rod 6. The second rotating motor 21 drives the first rotating device 4 to rotate, further increasing the degree of freedom of the fixed rod 6. The position of the fixed rod 6 can be flexibly and accurately adjusted to load cargo of different shapes and sizes.

Figure 2 Shown

[0029] When the first rotating device 4 is working, the first rotating motor drives the first rotating shaft 42 to rotate, and the first rotating shaft 42 drives the auxiliary rod 3 fixedly connected thereto to rotate, thereby changing the position of the fixed rod 6. The second rotating motor 21 can drive the first rotating device 4 to rotate through the first connecting member 41, thereby further adjusting the position of the fixed rod 6 to better adapt to different shapes and sizes of goods.

[0030] The rotation axis direction of the first rotary motor is perpendicular to the rotation axis direction of the second rotary motor 21, so that the movement range of the auxiliary rod 3 is maximized, thereby increasing the activity range of the fixed rod 6 and adapting to more goods of different shapes and sizes.

[0031] In this embodiment, two connecting rods 1 are included, each connecting rod 1 is connected to two main rods 2, and the connection point is located in the middle of the main rod 2, and each end of the main rod 2 is connected to a secondary rod 3. Providing two connecting rods 1 can reduce the load of a single connecting rod 1 and improve the bearing capacity of the mounting structure.

[0032] The fixing rod 6 is provided with a bottom support 61 for supporting the bottom surface of the cargo and a side support 62 for contacting the side of the cargo and limiting the horizontal movement of the cargo. When loading, the cargo is placed on the bottom support 61, and the side support 62 can limit the horizontal movement of the cargo, prevent the cargo from sliding off the bottom support 61, and achieve the fixing of the cargo.

[0033] There are at least two groups of fixing rods 6, the bottom surface of the cargo is placed on the bottom support 61, and the sides of the cargo are clamped between the groups of side supports 62. Providing multiple groups of fixing rods 6 can make the cargo more firmly fixed, and reduce the requirements for the contact area between the bottom support 61, the side support 62 and the cargo; the sides of the cargo are clamped between the groups of side supports 62, so that the cargo can be balanced in the horizontal direction to avoid sliding.

[0034] like Figure 1 As shown, the side support 62 includes a first side support 621 and a second side support 622, the first side support 621 intersects with the second side support 622, the first side support 621 is fixedly connected to the bottom of the fixing rod 6, the bottom support 61 is fixedly connected to the bottom of the first side support 621, and the second side support 622 is fixedly connected to the edge of the upper surface of the bottom support 61. The first side support 621 and the second side support 622 respectively limit the horizontal movement of the goods in one direction, and the goods can be fixed in the horizontal direction through the cooperation of each group of the first side support 621 and the second side support 622.

[0035] In addition, it should be noted that the first side support 621, the second side support 622 and the bottom support 61 can also be connected by rotation, and the angle between the two side supports 62 can be changed by rotation, so as to adapt to goods of more shapes.

[0036] The cargo is loaded in the box 7, the horizontal cross section of the box 7 is a polygon, the number of the fixing rods 6 is equal to the number of sides of the box 7, and each corner of the box 7 fits with the bottom bracket 61 and the side bracket 62. The number of the fixing rods 6 is equal to the number of sides of the box 7, so that each corner of the box 7 can be installed between the bottom bracket 61 and the side bracket 62, and each corner of the box 7 fits with the bottom bracket 61 and the side bracket 62, which can prevent the box 7 from moving during the movement of the drone and ensure the stability of the box 7.

[0037] In this embodiment, the box body 7 is roughly a cube, which is stable in structure and convenient for transporting the box body 7. Accordingly, there are four sets of bottom brackets 61 and side brackets 62 to ensure that each bottom corner of the box body 7 is stuck between the bottom brackets 61 and the side brackets 62. In order to make the box body 7 parallel to the ground, each set of the first rotating device 4 and the second rotating motor 21 drives the fixing rod 6 to make each set of the bottom brackets 61 and the side brackets 62 have the same height and are mirror-symmetrical.

[0038] A second rotating device 5 is connected between the auxiliary rod 3 and the fixed rod 6. The second rotating device 5 can adjust the relative angle between the fixed rod 6 and the auxiliary rod 3, so that the bottom bracket 61 and the side bracket 62 are always in contact with the box body 7, and are not affected by the position change of the fixed rod 6. In this embodiment, the second rotating device 5 can keep the fixed rod 6 vertical all the time, and the end faces of the bottom bracket 61, the first side bracket 621, and the second side bracket 622 are all perpendicular to the fixed rod 6, and the bottom bracket 61 is perpendicular to the side bracket 62 to adapt to the cubic structure of the box body 7; the connection points of the bottom bracket 61, the first side bracket 621 and the fixed rod 6 overlap in the vertical direction, and are respectively located near the ends of the bottom bracket 61 and the first side bracket 621, so as to increase the contact area between the bottom bracket 61, the first side bracket 621 and the box body 7; the vertical fixed rod 6 can also play an auxiliary role in limiting the horizontal movement of the box body 7.

[0039] The structure composed of the main rod 2, the auxiliary rod 3 and the fixed rod 6 is mirror-symmetrical with respect to the connecting rod 1, so that the force of the mounting structure is more balanced, and it is also beneficial to keep each group of bottom supports 61 and side supports 62 on the same horizontal line during movement, so that the box body 7 remains horizontal.

[0040] In this embodiment, a plurality of through holes are provided on the side surfaces of the auxiliary rod 3 and the fixing rod 6, so as to reduce the weight of the mounting structure and the energy consumption of the UAV.

The bottom of each corner of the box cover 71 is respectively in contact with each group of the bottom brackets 61, and the side of each corner of the box cover 71 is in contact with the side brackets 62. Figure 3 shown.

[0043] The bottom area of ​​the box cover 71 is larger than the box bin 72, and the exposed part abuts against the bottom support 61 and the side support 62, so that the box cover 71 is fixed between each group of fixing rods 6, thereby fixing the box bin 72; by fixing the box cover 71 to fix the box body 7, the height of the box body 7 that can be accommodated by the mounting structure is increased.

[0044] In this embodiment, the box cover 71 and the box compartment 72 are connected by a buckle 73, which has a simple structure and is convenient for disassembly and installation of the box cover 71. When loading, the buckle 73 is opened, the goods are filled into the box compartment 72, the box cover 71 is closed, the buckle 73 is closed, and the box cover 71 is fixed between the groups of fixing rods 6, so that the goods will not fall during the transportation of the drone.

This embodiment is similar to the first embodiment, except that the second rotating device 5 includes a second connecting member 51, a third rotating motor, a second rotating shaft 52 and a second shaft seat 53.
