[0002] A drone is an unmanned aircraft, and its flight operation is usually controlled by a remote control, a preset route or an autonomous computer program. Drones mainly rely on multiple arms, multiple brushless motors and multiple rotors to take off. The arms are installed on the fuselage, the brushless motors are installed away from the fuselage, and the rotors are connected to the brushless motors. For beginners who remotely control drones, a protective frame is generally installed on the outside of the rotors to prevent the high-speed rotating rotors of the flying drone from contacting objects such as walls and causing damage and falling.

[0003] The existing drone rotor protection frame is mainly fixed to the arm through the buckle connected at its end, and the buckle can only be fixed to the drone arm of one shape. The shape of the drone arm is cylindrical, square and of different thicknesses. It is often necessary to customize the protection frame according to the shape of the drone arm, which not only increases the manufacturing cost and complexity, but also brings certain troubles to the user's choice. It is necessary to ensure that the purchased protection frame is compatible with their own drone. To this end, we propose a drone anti-fall kit. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1: Please refer to Figure 1-Figure 5 The figure shows an anti-fall kit for unmanned aerial vehicles, including a connecting plate 5, a connecting disk 6 is fixedly connected to the rear end of the connecting plate 5, a plurality of L-shaped rods 9 are fixedly connected to the outer wall of the connecting disk 6 in a circular array around its center, and an arc rod 8 is fixedly connected to the top ends of the plurality of L-shaped rods 9. The front end of the connecting plate 5 is elastically connected to a connecting block 4 through a buffer component, and the front end of the connecting block 4 is fixedly connected to a supporting plate 2. Both side walls of the supporting plate 2 are fixedly connected to splicing blocks 14, and the upper ends of the two splicing blocks 14 are fixedly connected to studs 3. The outer walls of the two studs 3 are slidably sleeved with U-shaped blocks 13, and a V-shaped clamping plate 1 is fixedly connected between the two U-shaped blocks 13. The outer walls of the two studs 3 are provided with spinning parts.

[0021] The spinning part includes a pressing ring 10 , which is threadedly sleeved on the outer wall of the stud 3 , and the lower end of the pressing ring 10 is in contact with the upper end of the U-shaped block 13 .

[0022] The outer wall of the pressing ring 10 is provided with a plurality of anti-skid grooves 11, which are arranged in a circular array around the center of the pressing ring 10; specifically, by providing the anti-skid grooves 11, an anti-skid effect can be achieved when the pressing ring 10 is rotated.

[0023] A positioning plate 7 is fixedly connected to the upper edge of the connecting plate 6, and the positioning plate 7 is arc-shaped; specifically, the arc-shaped positioning plate 7 can be more closely attached to the end of the drone arm away from the fuselage.

[0024] The inner V-surface of the V-shaped clamping plate 1 is fixedly connected with a V-shaped rubber pad 17 . Specifically, by providing the V-shaped rubber pad 17 , it is possible to prevent the V-shaped clamping plate 1 from damaging the arm of the drone.

[0025] The lower ends of the two U-shaped blocks 13 are penetrated with holes 18, and the two holes 18 are respectively slidably matched with the two studs 3; specifically, by providing the holes 18, it is convenient for the U-shaped block 13 to be movably sleeved outside the studs 3.

[0026] In this embodiment, firstly, the two pressure rings 10 are screwed upward out of their respective corresponding studs 3 and the V-shaped clamp 1 is removed. The V-shaped clamp 1 can leave the corresponding stud 3 together with the two U-shaped blocks 13, and then the connecting plate 5 is attached to the lower end of an arm on the drone, and the positioning plate 7 on the connecting disk 6 is attached to the end of the drone arm away from the fuselage. The support plate 2, the connecting block 4 and the connecting disk 6 will also be attached to the lower end of the arm. Then, the V-shaped clamp 1 is held and the two U-shaped blocks 13 are respectively mounted on the outside of the two studs 3 until the inner V surface of the V-shaped clamp 1 is attached to the upper end of the drone arm. The inner V surface of the V-shaped clamp 1 can also be attached to the upper end of a columnar or square drone arm, and is suitable for different thicknesses.

[0027] Then, screw the two pressure rings 10 downward onto the outer walls of the two studs 3, respectively, until the lower ends of the two pressure rings 10 are tightly fitted onto the upper ends of the two U-shaped blocks 13, and then the V-shaped clamp 1 can press the drone arm tightly, thereby fixing the protection frame. There are two symmetrical contact positions between the V-shaped clamp 1 and the upper end of the drone arm, so that it can be stably fixed on the drone arm. Finally, the other protection frames can be fixed on the other arms of the drone in turn according to the same operation.

[0028] It should be noted that the drone rotor protection frame can be fixed on a columnar or square drone arm, and can be used for arms of different thicknesses, with good adaptability, so that it can be compatible with the installation of a variety of drones, and protect the rotors of a variety of drones to avoid the rotors of the drones from contacting the wall during flight and falling and being damaged. This not only reduces the cost and complexity of manufacturing, but also brings convenience to users' choices.

[0029] Example 2: Please refer to Figure 3 and Figure 4 This embodiment further explains the first embodiment. The buffer assembly in the figure includes a slot 15, which is opened at the front end of the connecting plate 5, and an insert block 12 is slidably inserted into the inside of the slot 15, and a spring 16 is symmetrically fixedly connected between the rear end of the insert block 12 and the inner wall of the slot 15, and the front end of the insert block 12 is fixedly connected to the rear end of the connecting block 4.

[0030] In this embodiment, when the drone approaches a wall during flight, if a collision occurs, the arc rod 8 contacts the wall, and the impact force generated on the drone when the arc rod 8 contacts the wall can be buffered to a certain extent through the cooperation of the slot 15, the spring 16 and the plug 12, thereby improving safety.
