[0002] UAVs with loading and carrying capabilities are relatively large in size and occupy a certain amount of space each time they are placed or transported. The arms of existing UAVs of this type are directly disassembled as a whole and placed separately after being disassembled. Moreover, the arms are made of metal materials as a whole and are relatively bulky.

[0003] Therefore, in order to correct the above defects, we propose a drone arm with a folding structure. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The utility model provides a technical solution:

[0020] See also Figure 1-3 A drone arm with a folding structure is mounted on the main beam of the drone fuselage and includes an arm body 1. The arm body 1 includes a snap-fitting piece 101 connected to the main beam, a square aluminum alloy forearm 102 connected to the snap-fitting piece 101, a carbon tube rear arm 106, a tube clamp 105 connected to the carbon tube rear arm 106, an end 104 connected to the tube clamp 105, and a clamping block 103 for connecting the end 104 and the square aluminum alloy forearm 102. The drone propeller is mounted on the end of the carbon tube rear arm 106.

[0021] A plurality of threaded holes 109 are provided on the engaging part 101 and the square aluminum alloy forearm 102, and the threaded holes 109 on the two correspond one to one. The engaging part 101 is composed of two aluminum alloy plates, and the front ends of the two aluminum alloy plates are respectively installed on the upper and lower ends of the main beam by screws, and the end ends of the two aluminum alloy plates are respectively installed on the upper and lower ends of the square aluminum alloy forearm 102 by screws.

[0022] That is, by disassembling and assembling the screws, the installation direction and angle of the square aluminum alloy forearm 102 on the bite part 101 are changed. When the drone needs to work, the square aluminum alloy forearm 102 and the bite part 101 are in the same straight line. When it needs to be stored, the square aluminum alloy forearm 102 and the bite part 101 can be bent. At this time, the square aluminum alloy forearm 102 is parallel to the main beam. Since there are more threaded holes 109 on the square aluminum alloy forearm 102 and the bite part 101, when the square aluminum alloy forearm 102 and the bite part 101 are bent, the end of the square aluminum alloy forearm 102 in the bite part 101 can be slightly moved toward the entrance end of the bite part 101, so that there is a certain distance between the square aluminum alloy forearm 102 and the main beam, leaving space for the propeller.

[0023] Among them, since the square aluminum alloy forearm 102 and the bite part 101 are fixed with screws, considering the stability, an L-shaped angle iron 107 is installed in the angle between the square aluminum alloy forearm 102 and the main beam. The two sides of the angle iron 107 are respectively connected to the square aluminum alloy forearm 102 and the main beam by screws, so as to improve the stability of the square aluminum alloy forearm 102.

[0024] Considering that there are a large number of arms on the drone, the square aluminum alloy forearm 102 and the carbon tube rear arm 106 are folded together, which will cause insufficient accommodation space. Therefore, the square aluminum alloy forearm 102 and the carbon tube rear arm 106 need to be folded once. Specifically, a plurality of threaded holes 109 are also provided on the clamping block 103, and the threaded holes 109 on the clamping block 103 correspond one-to-one to the threaded holes 109 on the square aluminum alloy forearm 102. The clamping block 103 consists of two upper and lower clamping plates. The end of the square aluminum alloy forearm 102 and the end of the end head 104 are located between the two clamping plates, and the end of the square aluminum alloy forearm 102 and the end of the end head 104 are connected to the clamping plates by screws.

[0025] Through the above, the square aluminum alloy forearm 102 and the carbon tube rear arm 106 can be folded. After folding, the carbon tube rear arm 106 is parallel to the square aluminum alloy forearm 102. When folding, there are many threaded holes 109 on the square aluminum alloy forearm 102, the end head 104 and the clamping block 103, and the position of the end head 104 in the clamping block 103 can be changed, so that there is a certain distance between the square aluminum alloy forearm 102 and the carbon tube rear arm 106, making room for the propeller at the end of the carbon tube rear arm 106. After the second folding, the length of the entire arm is shortened, which adapts to more arms being folded together on the drone.

[0026] In addition, when there are a large number of them on the drone, the arm is installed at the corner of the main beam, and the aluminum alloy plate of the bite part 101 is connected to one end of the square aluminum alloy forearm 102 in a long fan-shaped structure, so that two square aluminum alloy forearms 102 can be installed at the end of such a bite part 101 at the same time, and the aluminum alloy plate of the bite part 101 connected to the middle position of the main beam is in a long rectangular shape, so that only one square aluminum alloy forearm 102 is installed at the end of such a bite part 101.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
