Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0023] figure 1 A schematic structural diagram of a light-weight landing gear for a solar-powered UAV provided by an embodiment of the present invention is shown. like figure 1 As shown, a lightweight landing gear for a solar-powered drone includes a bicycle tire 1 , a bicycle front fork 2 , a connecting assembly, a landing gear strut 11 and a sleeve 12 . in,

[0024] The bicycle tire 1 is connected with the bicycle front fork 2 through a bearing. It should be understood that the manner in which the bicycle tire 1 is connected to the bicycle front fork 2 through a bearing is a well-known manner, and will not be described in detail in this embodiment. The buffer capacity of the bicycle tire itself in this embodiment can realize energy absorption when the solar drone is landed, thereby advantageously protecting the solar drone.

[0025] The bicycle front fork 2 is ...

Abstract

The invention discloses a light-weight landing gear for a solar unmanned aerial vehicle, comprising: a bicycle tire, a bicycle front fork, a connecting assembly, a landing gear pillar and a sleeve; wherein, the bicycle tire is connected to the bicycle front through a bearing The fork is connected; the bicycle front fork is connected with the landing gear strut through the connecting assembly; the sleeve is sleeved on the outer surface of the landing gear strut and connected with the connecting assembly. The bicycle front fork of the present invention is connected with the landing gear strut through the connecting assembly, while reducing the structural weight, it also enhances its applicability to the flying field, and has the advantages of simple structure and low manufacturing cost.

Description

technical field [0001] The invention relates to the field of solar-powered aircraft, in particular to a lightweight landing gear for a solar-powered drone. Background technique [0002] At present, domestic and foreign solar aircraft mainly include the American NASA series, the Swiss Solar Impulse series and the British Zephyr series. Among them, the NASA series UAV landing gear protrudes forward and downward from the main beam through the connecting piece and installs two main load-bearing struts respectively. Wheels, and together with other rectification and support structures form the landing gear structure, which is mainly suitable for flying wing layout, and the structure is relatively complex; while the Zephyr series and the recent solar drone developed by Google have no landing gear structure, and its The initial power is provided by people or other external forces to realize the take-off of the UAV. The propeller is fixed in a position parallel to the wing by parking...
