The arm of an unmanned aerial vehicle is an important component for supporting the flight of the unmanned aerial vehicle, and the stability of its structure and the convenience of installation directly relate to the overall performance and service efficiency of the unmanned aerial vehicle.

[0003] The traditional installation structure of the arm of an unmanned aerial vehicle often uses two semi-circular parts, which are fixed or welded by bolts. This split structure is not easy to position during installation. Fixing or welding with two bolts not only makes the installation process cumbersome, but also extremely inconvenient when disassembling and replacing the arm, greatly reducing the installation and maintenance efficiency of the unmanned aerial vehicle.

[0062] As shown in the figure, a drone includes an installation component 4, a stabilizing component 6, a plurality of arms 2 and a plurality of propeller components 3. A first vertical support member is installed between the installation component 4 and the stabilizing component 6. The plurality of arms 2 are all installed at the installation component 4, and one of the propeller components 3 is installed at each arm 2.

[0064] As Figure 2B 、 3 shown, the installation component 4 includes two installation plates 4.1 and a plurality of connection components 4.2 connected between the two installation plates 4.1. The top of the connection component 4.2 is fixedly connected to the upper installation plate 4.1, and the bottom is fixedly connected to the lower installation plate 4.1. The arm 2 passes through the connection component 4.2 and is fixedly connected to the connection component 4.2. Each arm 2 passes through two connection components 4.2. The top of the connection component 4.2 and the upper installation plate 4.1 are fixedly connected by a top bolt 4.3, and the bottom of the connection component 4.2 and the lower installation plate 4.1 are fixedly connected by a bottom bolt 4.4; the connection component 4.2 has a jack 4.2.1 through which the arm 2 can pass and an opening 4.2.2 communicating with the jack 4.2.1. The connection component 4.2 also has an adjusting member 4.5 capable of adjusting the size of the opening 4.2.2. The adjusting member 4.5 is a bolt, a screw or a pin.

[0065] There are multiple connection components and they are fixedly installed between the two installation plates, so that the structure of the installation component is stable and it is convenient to install the arms subsequently. When installing the arm 2 of the drone, the arm 2 is inserted into the connection component 4.2, and the adjusting member 4.5 can adjust the connection component to make the opening smaller, so that the connection component 4.2 and the arm 2 are fixedly connected. When disassembling, only need to adjust (or disassemble) the adjusting member to make the opening of the connection component larger, and the arm can be disassembled. And there are two connection components at each arm, so that the installation of the arm is more stable.

[0066] As shown Figure 2A in the figure, the propeller assembly 3 includes two propeller units. Each propeller unit includes a fixed seat 3.1, a carrier plate 3.2 fixedly connected to the fixed seat 3.1, a power source 3.3 mounted on the carrier plate 3.2, and a propeller blade mounted on the power source 3.3. The fixed seats 3.1 of the two propeller units wrap the arm 2 and are fixedly connected to each other. The fixed seats 3.1 of the two propeller units are fixedly connected by bolts, screws or pins. The fixed seat 3.1 has a groove matching the shape of the arm 2.

[0067] By fixedly connecting the two fixed seats, the two fixed seats can be fixedly connected to the arm, thereby realizing the installation of the propeller assembly. And the propeller assembly has double propeller blades, thus providing greater lift.

[0068] As shown Figure 4 in the figure, the stabilizing assembly includes a first substrate 6.1, a second substrate 6.2, and a support assembly located between the first substrate 6.1 and the second substrate 6.2. The top of the support assembly has a plurality of first protrusions 6.3.1, and the bottom has a plurality of second protrusions 6.3.2. The first substrate 6.1 has a plurality of first card slots matching the first protrusions 6.3.1, and the second substrate 6.2 has a plurality of second card slots matching the second protrusions 6.3.2. The support assembly includes three support plates 6.3, and the three support plates 6.3 are fixedly connected to each other by clamping. The top of each support plate 6.3 has two first protrusions 6.3.1, and the bottom has two second protrusions 6.3.2. The three support plates 6.3 are distributed in an equilateral triangle. The top of each support plate 6.3 has an upper card slot, and the bottom has a lower card slot. A plurality of tripod sleeves 6.4 are fixed to the stabilizing assembly 6, and a tripod 6.5 is fixed to each tripod sleeve 6.4. The tripod sleeve 6.4 and the first substrate 6.1 are fixedly connected by bolts. The tripod sleeve 6.4 and the tripod 6.5 are fixedly connected by bolts.

[0069] Due to the tight connection between the first substrate, the second substrate and the three support plates, the structural strength of the bottom of the drone is increased, and the ability to resist deformation is improved. The stabilizing assembly disperses the impact force generated during landing and distributes the force evenly to the entire bottom structure, thereby reducing the pressure borne by a single part. This not only protects the tripod from deformation, but also ensures the stability of the drone after landing.

[0070] As shown Figure 2As shown, the mounting assembly 4 is further connected with a top fixing plate 7 through a second vertical support member. The first vertical support member includes a plurality of first vertical rods 5.1; the second vertical support member includes a plurality of second vertical rods 5.2. The first vertical rod 5.1 and the first substrate 6.1 are fixedly connected by bolts. The first vertical rod 5.1 and the lower mounting plate 4.1 are fixedly connected by bolts. The second vertical rod 5.2 and the top fixing plate 7 are fixedly connected by bolts. The second vertical rod 5.2 and the upper mounting plate 4.1 are fixedly connected by bolts. The drone further includes a top housing 1.1 fixedly connected with the top fixing plate 7, a bottom housing 1.4 fixedly connected with the stabilizing assembly 6, a first housing 1.2 located between the mounting assembly 4 and the stabilizing assembly 6, and a second housing 1.3 located between the mounting assembly 4 and the top fixing plate 7; the first housing 1.2 includes a plurality of first side plates, and the second housing 1.3 includes a plurality of second side plates. The number of the first side plates is equal to the number of the arms, and the first side plates are arc-shaped. The number of the second side plates is equal to the number of the arms, and the second side plates are arc-shaped. Both the top housing 1.1 and the bottom housing 1.4 are bullet-shaped. The top housing 1.1 and the top fixing plate 7 are fixedly bonded by glue. The bottom housing 1.4 and the stabilizing assembly 6 are fixedly bonded by glue.

[0071] The top housing gradually decreases in the axial upward direction; designed in this way, when the drone is flying in the air, the air resistance is effectively reduced, enabling the drone to pass through the air more efficiently; it helps to increase the flight speed of the drone, reduce energy consumption, and improve the overall flight stability.

[0072] The bottom housing gradually decreases in the axial downward direction; designed in this way, it helps to enhance the structural strength of the drone body; effectively disperse and withstand the pressure and impact from below, so that the drone can better resist damage when landing or being externally impacted.

[0073] Although the present invention has been illustrated and described with respect to the preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention as long as they do not exceed the scope defined by the claims of the present invention.
