[0002] The characteristics of long flight time, light weight, low cost, high maneuverability, high safety, and high concealment are the development direction of UAVs. The above characteristics of UAVs mainly depend on their structural form and material selection. At present, the main beam structure of UAVs has a large deadweight, which makes it difficult to effectively reduce the weight of UAVs. In addition, it is not convenient to hang objects on the main beam structure, which makes it more troublesome to load materials when UAVs are used to transport materials.

[0003] To this end, we propose a main beam structure of a UAV with a hanging point to solve the above problems. Utility Model Content

[0026] See also Figure 1-6 A main beam structure of a drone with a hanging point includes a base frame 1 and a main beam frame 2. The main beam frame 2 is installed on the base frame 1, and connecting arms 3 for connecting the drone rotors are installed at the corners of the main beam frame 2. A flat connecting plate 6 is provided between the upper and lower planes of the main beam frame 2 and the connecting arm 3. The flat connecting plate 6 is locked and connected to the main beam frame 2 and the connecting arm 3 by bolts. At the same time, the vertical surfaces of the main beam frame 2 and the connecting arm 3 are locked and connected by right-angle connectors 7 and bolts. A mounting frame 4 is fixed inside the main beam frame 2, and a hanging frame 5 is provided under the mounting frame 4. Among them, the base frame 1 is made of carbon fiber material, and the main beam frame 2, the connecting arm 3, the mounting frame 4 and the hanging frame 5 are made of aluminum alloy material, which is conducive to reducing the dead weight.

[0027] Furthermore, a number of through holes 8 are evenly opened on the surface of the main beam frame 2 and the connecting arm 3, which is conducive to further reducing the dead weight, and the through holes 8 on adjacent sides are staggered with each other, thereby ensuring the structural firmness of the main beam frame 2 and the connecting arm 3.

[0028] The hanging frame 5 includes a row of hollow frames 51, which can not only reduce their own weight but also facilitate loading of items. Frame plates 52 are sleeved on the outer sides of both ends of each hollow frame 51, and the frame plates 52 are locked and connected to the hollow frame 51 by bolts. The top edges of the frame plates 52 are fixed to the main beam frame 2 by bolts, and fastening strips 53 are fixed between adjacent frame plates 52 by bolts. The top ends of the fastening strips 53 are fixed to the main beam frame 2 by bolts. A vertical hanging strip 54 is installed in the middle of the end of the hollow frame 51, and the bottom end of the hanging strip 54 is hingedly connected to the lower edge of the hollow frame 51, and the top end of the hanging strip 54 is connected to the upper edge of the hollow frame 51 by a spring buckle 55 and a hook 56, wherein the spring buckle 55 is installed on the hanging strip 54, and the hook 56 is installed on the hollow frame 51, so that the hanging strip 54 can be opened for hanging items.

[0029] Furthermore, inclined reinforcement strips 57 are installed at the end corners of the hollow frame 51, which is beneficial to enhance the strength of the hollow frame 51 and thereby reduce the problem of deformation thereof when hanging heavy objects.

[0030] The base frame 1 includes a pair of parallel bottom rods 11, and each bottom rod 11 is connected to a pair of parallel oblique support rods 12 through a T-shaped connecting sleeve 14. The top end of the oblique support rod 12 is connected to the flat connecting plate 6. A horizontal support rod 13 is connected between each pair of oblique support rods 12 through a T-shaped connecting sleeve 14, and a horizontal support rod 13 is also connected between the two pairs of oblique support rods 12 through a Y-shaped connecting sleeve 15. The entire base frame 1 has a hollow trapezoidal structure to ensure the stability of the support of the main beam frame 2 during the lifting and lowering process.

[0031] Furthermore, considering that the bottom rod 11 needs to directly contact the ground when rising and falling, which is easy to increase wear, a protective sleeve 9 is sleeved on the outer periphery of the bottom rod 11. The protective sleeve 9 is made of wear-resistant rubber material, which is beneficial to extend the service life of the bottom rod 11.
