Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicle protection covers, and more specifically, to a multi-rotor unmanned aerial vehicle propeller wing protection cover. Background Art

[0002] Drones are a general term for unmanned aerial vehicles. They are equipped with flight controllers, GPS and other equipment, and can be tracked and positioned by ground stations or pilots. The propellers of drones may be damaged by colliding with objects during flight, or may injure pedestrians during flight. The use of propeller protection covers can avoid damage to the drone frame and reduce accidental injuries to pedestrians.

[0003] The current multi-rotor UAV propeller protection cover, such as the "A UAV propeller protection cover and UAV" proposed with patent number 202023259263.4, includes multiple arc-shaped guard rods, multiple connecting rods and retaining rings. The connecting rods are arranged radially with the retaining ring as the center, and the connecting rods include an integrally formed horizontal portion and a bent portion. The multiple connecting rod horizontal portions are fixedly connected by a third arc-shaped guard rod, and the multiple connecting rod bent portions are fixedly connected at the corners by a second arc-shaped guard rod. The ends of the multiple connecting rod bent portions away from the horizontal portions are fixedly connected by the first arc-shaped guard rod. The setting of the utility model provides a UAV propeller protection cover with better protection effect and easy disassembly and installation.

[0004] The existing multi-rotor UAV propeller wing protection cover is installed on each propeller of the UAV in sequence. Although it can protect the UAV propeller wings, in actual use, multiple protection covers are installed on each rotor of the UAV in sequence, and each protection cover needs to be fixed to the body. The installation process is time-consuming, and the protection covers need to be removed one by one, which is laborious and affects the use. Therefore, there is an urgent need to improve the technology of the propeller wing protection cover structure of multi-rotor UAV to improve this equipment. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a multi-rotor UAV propeller wing protective cover, which can be used for the use of the multi-rotor UAV propeller wing protective cover. The mounting sleeve can be installed on the mounting seat of the UAV body through the support leg sleeve, and the mounting sleeve can be threadedly installed thereon through the threaded connection formed by the mounting sleeve and the mounting seat. At the same time, the rotation angle of the rotating sleeve can be swung so that the guide rod groove and the guide rod are on the same vertical line. At this time, the support frames around the rotating sleeve correspond to the propeller one by one, and then the upper protective cover is connected to the lower protective cover through a snap-on mechanism to cover and protect the propeller and rotor, so as to avoid the UAV body from colliding during flight or damaging the UAV body due to the propeller being entangled on leaves. The device can drive multiple protective covers directly to the rotor and propeller, and there is no need to connect the protective covers to the UAV body in turn, which saves time and effort and is more convenient to disassemble.

[0028] The mounting sleeve 7 is sleeved onto the mounting seat 2 of the drone body 1 through the supporting legs 3, and the mounting sleeve 7 is threadedly mounted thereon through the threaded connection formed by the mounting sleeve 7 and the mounting seat 2. At the same time, the rotation angle of the rotating sleeve 8 can be swung so that the guide rod groove 9 and the guide rod 10 are on the same vertical line. At this time, the support frames 11 around the rotating sleeve 8 correspond to the propeller 6 one by one, and then the upper protective cover 13 is covered on the lower protective cover 12 through the snap-fit ​​mechanism to cover and protect the propeller 6 and the rotor 5 to prevent the drone body 1 from colliding during flight or being damaged by the propeller 6 being entangled on leaves. The device can directly drive multiple protective covers to the rotor 5 and the propeller 6, without the need to connect the protective covers to the drone body 1 in turn, saving time and effort, and being relatively convenient to disassemble.

[0029] See also Figure 2-4 The cross-sections of the mounting sleeve 7 and the rotating sleeve 8 are both annular, and the centers of the cross-sections of the mounting sleeve 7 and the rotating sleeve 8 coincide with each other.
