Embodiment Construction

[0019] Refer to attached figure 1 A carbon fiber landing gear device for an unmanned helicopter, comprising a base of the unmanned helicopter and a carbon fiber installation platform 1, a first buffer pad 2, and a carbon fiber beam 4 connected and fixed by standard parts through the installation hole 3, and the upper plane of the carbon fiber installation platform 1 is provided with a mounting The hole 3 and the fixed concave frame for accommodating the first buffer pad 2, the three-circle fixed position of the carbon fiber installation platform 1 and the shape of the carbon fiber beam 4 are closely matched in three axes. The carbon fiber installation platform 1 uses carbon fiber reinforced resin raw materials to form parts through a tooling mold at one time, and the carbon fiber beam is fixed with epoxy resin, and stainless steel rivets 19 are used for assembly on the side.

[0020] The carbon fiber beam 4, the carbon fiber beam arc portion 5, and the carbon fiber support col...

Abstract

The invention belongs to the technical field of unmanned helicopters and particularly relates to an unmanned helicopter carbon fiber undercarriage apparatus, comprising an unmanned helicopter base, a mounting platform, cushions A and carbon fiber cross beams fixedly through mounting holes; the carbon fiber cross beams, carbon fiber cross beams R and carbon fiber support posts are integrated rectangular tubes; carbon fiber tee connectors are fitted in lower rectangular tubes of the carbon fiber support posts, and rectangular pads and buffer rings B are fitted in upper rectangular tubes of the carbon fiber support posts that are then fixed through buffer shafts; carbon fiber slides are fitted into lower slotted round tubes of the carbon fiber connectors and are fixed to bottom platform buffer pads C through rivets; the unmanned helicopter carbon fiber undercarriage apparatus has the advantages that the carbon fiber undercarriage is 50% lighter than an aluminum alloy undercarriage, 0.8 kg of stainless steel buffer assembly is omitted for the aluminum alloy undercarriage, and the unmanned helicopter can bear more weight and travel longer; the buffer devices A, B and C for the carbon fiber undercarriage protect instruments and devices; the carbon fiber undercarriage apparatus is light, strong and tough and enables prolonged maintenance time of the unmanned helicopter and decreased potential hazards and operation cost.

Description

technical field [0001] The invention belongs to the technical field of unmanned helicopters, in particular to a carbon fiber landing gear device for unmanned helicopters. Background technique [0002] At present, the slides, beams, and support columns of the landing gear of unmanned helicopters are assembled by welding aluminum alloy profiles and connecting standard parts. The aluminum alloy landing gear of unmanned helicopters will bend and deform under the impact of frequent take-offs and landings. The use time is short; if the thickness of the aluminum alloy profile is thickened, the unmanned helicopter will be overweight; the aluminum alloy landing gear of the unmanned helicopter must be equipped with a first-level buffer assembly on the beam to protect the equipment of the drone, 0.8kg stainless steel The buffer assembly increases the manufacturing cost and also increases the weight of the landing gear of the drone; the overweight of the aluminum alloy landing gear of t...
