Embodiment 1
[0030] like Figure 1-3 As shown, a kind of unmanned aerial vehicle landing gear, comprises landing gear body 1, and described landing gear body 1 is folded / compressed rear shock absorption, and described landing gear body 1 is provided with energy storage device, and described landing gear body 1 is folded After being compressed, the energy storage device is charged, and the energy storage device is used to provide power when the landing gear body 1 is deployed. It can be understood that during the folding / compression process of the landing gear body 1, the energy storage device can be charged through its mechanical movement, so as to ensure that the stored energy can be used when the UAV takes off. power, so as to achieve the purpose of reducing energy consumption.
[0031]The landing gear body 1 includes a connecting frame 11 and a contact frame 12. One end of the connecting frame 11 and the contact frame 12 is hinged, and the fixed end 15 of the sliding rod 13 is hinged o...
Embodiment 2
[0036] The difference from the above-mentioned embodiment is that the landing gear of a UAV provided in this embodiment includes a landing gear body 1, which is shock-absorbed after being folded / compressed, and the landing gear body 1 is provided with There is an energy storage device, and the energy storage device is charged after the landing gear body 1 is folded / compressed, and the energy storage device is used to provide power when the landing gear body 1 is deployed; the landing gear body 1 is provided with an airbag, so The folding / compressing distance of the landing gear body 1 provides space for the deployment of the airbag. In this embodiment, the landing gear body 1 is combined with the airbag. When the UAV fails to land, the folding / compression distance between the connecting frame 11 and the contact frame 12 can provide space for the expansion of the airbag, ensuring At touchdown, the airbags are fully deployed.
[0037] The landing gear body 1 includes a connecti...
Embodiment 3
[0043] Based on the first and second embodiments above, this embodiment provides a fall-resistant energy storage method for the landing gear of a drone. The specific method is as follows:
[0044] Landing in normal state: After the landing gear body 1 touches the ground, the propeller of the UAV is powered off, and the landing gear body 1 starts to fold / compress. During the folding / compression process, the deformation energy of the landing gear body 1 is stored; at the same time The exhaust gas discharged from the engine of the UAV is compressed by the compressor and filled into the gas cylinder 3 provided on the landing gear body 1 for storage; when the UAV takes off, the energy and gas stored in the folding / compression of the landing gear body 1 The gas stored in the bottle 3 is released together to provide power assist for the take-off of the UAV; the energy released by the spring 14 and the energy released by the gas bottle 3 are respectively located at the front end and th...
