DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Example 1

[0026] like Figure 1-4 As shown, the utility model provides a tool-free fast-folding arm, including a fuselage 1, an arm 4 and a wing 2, the wing 2 and the arm 4 are both arranged on the fuselage 1, the arm 4 includes a rear arm 41 and a front arm 42, one end of the rear arm 41 is provided with an arm rear folding piece 6, one end of the front arm 42 is provided with an arm front folding piece 5, the arm front folding piece 5 is connected to the arm rear folding piece 6 through a fixed end 8, the arm rear folding piece 6 is provided with a ball pin 7, the fuselage 1 is connected to the wing 2 through a carbon tube, the wing 2 includes an outer wing 21 and an inner wing 22, the outer wing 21 is provided at one end of the inner wing 22, the arm 4 is fixedly installed with the fuselage 1 by screws, and a tail wing 3 is provided on the fuselage 1, and the tail wing 3 is connected to the arm 4 through a tail wing quick-plug docking structure.

[0027] In this embodiment, the front machine arm 42 and the rear machine arm 41 are assembled into a whole through the front machine arm folding member 5 and the rear machine arm folding member 6. After the front machine arm folding member 5 and the rear machine arm folding member 6 are respectively bonded with the corresponding machine arms with resin, after the resin is cured, rivets are used to complete the riveting, so as to enhance the force bearing capacity of the structural parts and the machine arms. After all the avionics equipment of the rear machine arm 41 and the front machine arm 42 are assembled with the rear motor, the electric adjustment and the pre-embedded assembly connector, in the process of assembling the rear machine arm 41 and the front machine arm 42, because the front machine arm folding member 5 and the rear machine arm folding member 6 are a pair of folding members that can be fixed and disassembled, this During the bonding process of the folding parts, it is necessary to distinguish the folding direction of the folding parts according to the orientation of the carbon tubes of the machine arm 4 to avoid incorrect bonding and damage to the parts. After correct identification, use a fixing part to fix the concentric hole at one end into an assembly to form a fixed end 8, and use a ball pin 7 to connect the other side. During the folding and storage process, it is only necessary to pull up the ball pin 7 and fold and store it according to the folding direction. During the unfolding process, it is rotated and unfolded along the inherent direction until the two corresponding folding part holes coincide concentrically, and the ball pin 7 is inserted to fix it. This ball pin 7 will not fall off due to the vibration of the machine body because there is a corresponding clamping column at the bottom.

[0028] Example 2

[0029] like Figure 5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the outer wall of the rear folding part 6 of the arm is fixedly connected with a fixing block 10, the outer wall of the front folding part 5 of the arm is fixedly connected with a fixing rod 9, a fixing groove 11 is opened on the fixing block 10, one end of the fixing rod 9 is arranged inside the fixing groove 11, the fixing block 10 is threadedly connected with a fastening bolt 12, and one end of the fastening bolt 12 abuts against the outer wall of the fixing rod 9, and the fixing rod 9 is fixed in the fixing groove 11 by arranging the fastening bolt 12.

[0030] In this embodiment, after the front arm 42 is folded, one end of the fixing rod 9 is rotated to the inside of the fixing groove 11, and then the fixing rod 9 can be fixed by tightening the fastening bolt 12, so that the front arm 42 remains in a folded state, thereby improving the stability after folding.

[0031] Example 3

[0032] A drone includes a tool-free, fast-folding machine arm.

[0033] The following is a detailed description of the working principle of the tool-free quick-folding arm and the drone.
