Detachable undercarriage and quadcopter

Abstract

The invention discloses a detachable undercarriage and a quadcopter. The undercarriage comprises an undercarriage main body, wherein a positioning post, a first button position, a second button position and surrounding ribs are arranged on the undercarriage main body; the surrounding ribs are fixedly connected with one another around the side of the undercarriage main body and form a containing groove with the undercarriage main body in an encircling way; a notch is formed in one side of the containing groove; the first button position and the second button position are respectively fixed on the surrounding ribs and are opposite to each other; the positioning post is positioned at the notch and is fixed on the undercarriage main body; two symmetrical clamping grooves are formed in two sides of the undercarriage main body; the two clamping grooves respectively correspond to the first button position and the second button position and are positioned below the surrounding ribs; an opening is formed in one end of each clamping groove; and the groove body of each clamping groove is transversely arranged. The undercarriage disclosed by the invention is convenient to assemble and detach by adopting a clamping mode, the stability performance is good by virtue of a crosswise fixing mode, and the undercarriage has a good shake-proof effect.

Description

technical field [0001] The invention relates to a four-axis aircraft, in particular to a detachable landing gear and the four-axis aircraft, which are applied to high-end intelligent aircraft. Background technique [0002] At present, there are more and more types of quadcopters on the market, some for aerial photography, some for toys and so on. On the quadcopter, in order to play a buffer role when landing or falling, to prevent the bottom of the product from being scratched and damaged, a landing gear is designed at the bottom to play a supporting and buffering role. The landing gear installed on the quadcopter on the market is mainly fixed by screws, and some are integrated with the main engine. After the undercarriage is damaged in such a combination mode, the undercarriage needs to be disassembled with a screwdriver and replaced with a new one, or it cannot be changed at all, which affects the appearance. However, the general landing gear combination structure is eas...

Problems solved by technology

In such a combination, after the landing gear is damaged, it is necessary to disassemble the landing gear with a screwdriver and replace it with a new one, or it cannot be replaced at all, which will affect the appearance

However, the general combination structure of the landing gear is easy to be damaged by collision with foreign objects. This inconvenient disassembly will bring troubles to the user for replacement, which is not conducive to the flight of the quadcopter.
