Description

Technical Field

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

[0002] Drones are increasingly entering our lives for aerial photography, communication, and targeted delivery. However, the more they are used, the more problems are exposed. When operating in forests or tunnels, novice users may make mistakes that could cause the high-speed drone to collide with trees or walls.

[0003] When using the above technology, the following technical problems were found in the existing technology: Existing drones require fully enclosed anti-collision protection for the drone rotors during flight to increase the protective effect of the drone rotors. However, the existing rotor cover is usually integrated with the drone, and some rotor covers are not fully enclosed, which makes it inconvenient to protect the drone rotors in all directions. In addition, the existing rotor cover is not convenient to disassemble and assemble, so as to repair and replace the drone rotors. To this end, we designed a drone protective cover to provide an alternative technical solution to the above technical problems. Utility Model Content

[0004] Therefore, it is necessary to provide a protective cover for drones to address the aforementioned technical problems. This cover is constructed by assembling four quarter covers to protect the rotor blades. Plastic bolts are then threaded through the quarter covers and connected to the mounting bracket for easy fixation. A top cover and a bottom cover are then used to snap the quarter covers together, creating a fully enclosed protective cover that protects the rotor blades. This design allows for easy assembly and disassembly of the four quarter covers, improving the protection of the drone rotor blades and facilitating maintenance and replacement of the drone rotor blades.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A protective cover for a drone includes a drone body, with connecting arms fixed at all four ends of the drone body. A mounting base is fixed at the end of each connecting arm away from the drone body. Mounting frames are fixed at all four ends of the outer side of the mounting base. A propeller is rotatably connected to the top and bottom of the mounting base. A quarter cover is fitted at the end of the mounting frame away from the mounting base. The four quarter covers are interlocked with each other. A top cover and a bottom cover are respectively interlocked at the top and bottom of the four quarter covers. An assembly mechanism is provided between the four quarter covers.

[0007] In a preferred embodiment of the UAV protective cover provided by this utility model, the assembly mechanism includes a plastic bolt, a threaded hole is provided inside the mounting bracket and at one end away from the mounting seat, the plastic bolt is threaded to the inside of the threaded hole, the end of the mounting bracket away from the mounting seat is slidably connected to the quarter cover, and the outside of the plastic bolt is slidably connected to the quarter cover.

[0008] In a preferred embodiment of the drone protective cover provided by this utility model, the four quarter covers are fixed with slots between each other, and two quarter covers are provided with blocks aligned with the slots, with one end of the slot engaging with the block.

[0009] In a preferred embodiment of the UAV protective cover provided by this utility model, the top and bottom ends of the four quarter covers are slidably connected to the top cover and bottom cover, respectively. The outer sides of the top cover and bottom cover are fixed with L-shaped buckles, and the bottom ends of the L-shaped buckles are engaged with the quarter covers.

[0010] As a preferred embodiment of the drone protective cover provided by this utility model, the top cover, bottom cover and quarter cover are made of polyvinyl chloride.

[0011] In a preferred embodiment of the drone protective cover provided by this utility model, the L-shaped buckle and the slot are made of polypropylene.

[0012] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0013] Meanwhile, through the above technical solutions, this utility model has at least the following beneficial effects: The drone protective cover provided by this utility model effectively installs and fixes four quarter covers to the mounting bracket through plastic bolts, thereby forming a circular protective cover. The top cover and bottom cover effectively protect the upper and lower parts of the propeller. The slots and corresponding blocks engage to improve the stability between the four quarter covers. The L-shaped buckles effectively engage and fix the top cover and bottom cover, and effectively increase the stability between the four quarter covers, the top cover and the bottom cover. Therefore, it is convenient to assemble and disassemble the drone propeller protective cover, and to repair and replace the drone propeller. Attached Figure Description
