Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a bionic spherical structure unmanned aerial vehicle. Background Art

[0002] Bionic drones are drones whose design is inspired by creatures in nature. These drones usually imitate the flight and behavioral characteristics of birds, insects or other animals to improve their performance in specific environments. Bionic drones have potential application value in many fields, such as environmental monitoring, search and rescue, agriculture, geological exploration, etc. Bird bionic drones imitate the flight characteristics of birds, such as gliding, hovering and rapid turning, etc. They usually have high stability and maneuverability and are suitable for performing tasks in complex environments. Insect bionic drones imitate the flight and behavioral characteristics of insects, such as bees and butterflies. They usually have strong environmental adaptability, can fly flexibly in narrow spaces, and can achieve hovering, inverted flight and other actions.

[0003] The existing bionic UAVs are relatively complex in structure and expensive in cost. Some bionic UAVs are equipped with protective spherical covers. However, the existing protective spherical covers are relatively closed in structure, which can easily affect the flight of the UAV. In addition, the installation of the existing protective spherical covers is relatively complex and not strong enough. After being hit, they may fall apart, resulting in the inability to protect the UAV. The existing bionic UAVs have no buffer when landing, which may reduce the service life of the UAV. Therefore, a bionic spherical structure UAV is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a bionic spherical structure drone to solve the problems raised in the above background technology.

[0009] Preferably, the number of the rotating shaft, the protection rod, the first through hole, the bolt, the second through hole and the nut is six, and the inner diameters of the first through hole and the second through hole are the same.

[0010] Preferably, the first mounting plate and the second mounting plate are the same in shape and size, and the number of the fixing plates and the power-assisted thrust fans are both four.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the threaded barrel, the fixing block, the rotating shaft, the protective rod, the first through hole, the first mounting plate, the bolt, the second mounting plate, the second through hole and the nut are provided, so that the resistance of the protective ball cover to the drone body is smaller, and the installation is more convenient and firm. When the protective ball cover needs to be installed, the threaded barrel is first screwed on the bottom end of the drone body, and then the protective rod is turned over, and the rotating shaft is rotated to align multiple protective rods, and then the bolt at the bottom end of the first mounting plate is inserted into the inner side of the first through hole, and the second through hole on one side of the second mounting plate is aligned with the bolt and pressed, and the nut is screwed on the outside of the bolt, and the installation of the protective ball cover can be completed.

[0013] 2. In the utility model, the fixed plate, power-assisted push fan, outrigger, fixed cylinder, limit rod, buffer spring and pad are arranged to buffer the drone body when it lands. When the drone takes off, starting the power-assisted push fan can increase the take-off speed of the drone. When the drone body is about to land, starting the power-assisted push fan can reduce the falling speed of the drone body and buffer the drone body. When the drone body lands, the pad first contacts the ground. At this time, the limit rod slides inside the fixed cylinder, and the buffer spring is compressed. The buffer spring can absorb part of the impact force of landing and buffer the drone body. BRIEF DESCRIPTION OF THE DRAWINGS
