Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a blade protection device for UAVs. Background Technology

[0002] Existing drone protective covers are typically fixedly installed on the outside of the blades, and this structure significantly interferes with airflow during drone flight. When the blades rotate, air must bypass or pass through the fixed structure of the protective cover, increasing air resistance around the blades. This not only directly affects the drone's flight efficiency but also reduces its maneuverability.

[0003] Therefore, the structural defects of traditional fixed protective shields have become a major bottleneck restricting the improvement of UAV performance. There is an urgent need to design a foldable protective shield that can be unfolded to provide protection when needed, and folded up during flight to reduce airflow interference, thus balancing protection and flight performance.

[0017] The technical advantage of adopting the above-mentioned further solution is that fixing with bolts makes it easy to disassemble the fixing frame.

[0018] In a preferred embodiment, a support is provided on the lower side of the main body.

[0019] The technical effect of adopting the above-mentioned further solution is that the drone is supported by the bracket.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In use, during the takeoff phase, when there is a lot of surrounding debris, the telescopic rod is driven to pull the protective bracket under the blades to protect them. After the drone takes off and the surrounding environment is stable and free of debris, the telescopic rod is driven in the opposite direction. The telescopic rod pushes the connecting block, and the connection between connecting rod one and connecting rod two controls the protective bracket to rotate in the opposite direction, thereby achieving the folding and storage of the protective bracket, reducing airflow interference, and balancing protection and flight performance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] For examples, please refer to Figures 1 to 5This utility model provides a technical solution: a blade protection device for a drone, including a body 100 and an arm 101. The arm 101 is fixedly mounted on its outer surface, and a protective component is provided on the outer surface of the arm 101. The protective component can be stored and includes a support plate 102 and a rotating plate 106. Two connecting plates 105 are fixedly installed at one end of the support plate 102, and the rotating plate 106 is rotatably installed between the two connecting plates 105. A buffer component is provided on one side of the rotating plate 106 to buffer and protect the protective component. The protective component also includes a telescopic rod 103, which is rotatably installed at one end of the support plate 102. A connecting block 104 is fixedly installed at the driving end of the telescopic rod 103. Connecting rods 107 are rotatably installed on one side of each of the two connecting plates 105, and a rotating shaft 109 is provided between the two connecting rods 107. The outer surface of the rotating shaft 109 is rotatably mounted on... Two connecting rods 108 are mounted on opposite sides of the outer surface of the rotating plate 106. A connecting block 104 is mounted on the outer surface of the rotating shaft 109. A protective bracket 110 is mounted on the outer surface of the rotating plate 106. The protective bracket 110 is made of carbon fiber composite material. The buffer assembly includes a spring 112 and a buffer plate 111. The buffer plate 111 is fixedly mounted inside the protective bracket 110. One end of the spring 112 is connected to one side of the rotating plate 106, and the other end of the rotating plate 106 is connected to one side of the buffer plate 111. A limit rod 113 is provided inside the spring 112. One end of the limit rod 113 is fixedly mounted on the outer surface of the rotating plate 106. A fixing frame 114 is fixedly mounted on the upper side of the support plate 102. The fixing frame 114 is fixedly mounted on the outer surface of the arm 101 by bolts 115. A bracket 116 is provided on the lower side of the body 100.

[0031] In this embodiment, during the ascent phase, the protective bracket 110 is initially positioned below the blades, in a protective state. When the protective bracket 110 encounters an obstacle, it rotates downwards and stretches the spring 112, thus providing a buffer and preventing breakage. A limit rod 113 is fixedly installed on one side of the rotating plate 106, which limits the protective bracket 110 and prevents it from rotating upwards and contacting the blades. When the drone takes off, the telescopic rod 103 is activated, pushing the connecting block 104 through its drive end. The connecting block 104 experiences a downward force, and since it is rotatably mounted on the outer surface of the rotating shaft 109, one end of the connecting block 104 is fixed. Two connecting plates 105 are installed, and a rotating plate 106 is rotatably installed between the connecting plates 105. Connecting rod 107 and connecting rod 2 108 are rotatably installed on both sides of the connecting plates 105 and the rotating plate 106, respectively. The other ends of connecting rod 107 and connecting rod 2 108 are rotatably installed on the outer surface of the rotating shaft 109. Due to the downward force on the connecting block 104, the connecting block 104 will push the rotating shaft 109 to rotate downward. Through the connection of connecting rod 107 and connecting rod 2 108, the rotating plate 106 will rotate between the connecting plates 105. The protective bracket 110 is rotatably installed on the outer surface of the rotating plate 106, so that the protective bracket 110 can be folded and stored. A fixing frame 114 is installed on the upper side of the support plate 102. The fixing frame 114 is fixedly installed on the outer surface of the arm 101 by bolts 115. When disassembly and maintenance are required, simply rotate the bolts 115 to remove it and complete the disassembly and maintenance of the protective component.

[0032] Working principle: During the ascent phase, the protective bracket 110 is initially positioned below the blades, in a protective state. When the protective bracket 110 encounters an obstacle, it rotates downwards and stretches the spring 112, providing a buffer and preventing breakage. A limit rod 113 is fixedly installed on one side of the rotating plate 106, limiting the protective bracket 110 and preventing it from rotating upwards and contacting the blades. When the drone ascends, the telescopic rod 103 is activated, pushing the connecting block 104 through its drive end. The connecting block 104 experiences a downward force. The connecting block 104 is rotatably mounted on the outer surface of the rotating shaft 109, with one end fixedly mounted... Two connecting plates 105 are installed, and a rotating plate 106 is rotatably installed between the connecting plates 105. Connecting rod 107 and connecting rod 2 108 are rotatably installed on both sides of the connecting plates 105 and the rotating plate 106, respectively. The other ends of connecting rod 107 and connecting rod 2 108 are rotatably installed on the outer surface of the rotating shaft 109. Due to the downward force on the connecting block 104, the connecting block 104 will push the rotating shaft 109 to rotate downward. Through the connection of connecting rod 107 and connecting rod 2 108, the rotating plate 106 will rotate between the connecting plates 105. The protective bracket 110 is rotatably installed on the outer surface of the rotating plate 106, so that the protective bracket 110 can be folded and stored. A fixing frame 114 is installed on the upper side of the support plate 102. The fixing frame 114 is fixedly installed on the outer surface of the arm 101 by bolts 115. When disassembly and maintenance are required, simply rotate the bolts 115 to remove it and complete the disassembly and maintenance of the protective component.
