Quick propeller mounting mechanism for multi-rotor aircraft

Abstract

The invention relates to a quick propeller mounting mechanism for a multi-rotor aircraft, which comprises a fixed base, wherein the fixed base comprises a base plate and at least one group of fasteners arranged on the base plate, and the opposite sides of the same group of fasteners are respectively provided with corresponding fastening grooves; connecting pieces, wherein corresponding sliding grooves are formed in the positions, corresponding to the buckling grooves, of the connecting pieces respectively, corresponding mounting holes are formed in the positions, on the outer sides of the sliding grooves, of the connecting pieces respectively, corresponding buckling shafts are movably mounted in the sliding grooves respectively, and the buckling shafts are detachably buckled in the corresponding buckling grooves respectively; a pressing mechanism which comprises mounting parts, wherein the inner ends of the mounting parts penetrate through the corresponding mounting holes and then are connected to the corresponding buckling shafts respectively; a reinforcing plate, the sides, not provided with the buckling grooves, of the fasteners abut against the inner sides of the reinforcing plates respectively; and a fixed connection cover plate used for connecting a propeller to the connecting piece. Assembly and operation stability of the propeller can be ensured, and the size and weight of the fixing base can be reduced.

Description

technical field [0001] The invention relates to a quick installation mechanism for a propeller of a multi-rotor aircraft, which is mainly used for quick installation of the propeller for a multi-rotor aircraft. Background technique [0002] A multi-rotor aircraft refers to a special flight device with three or more rotor shafts, which is equipped with a motor on each shaft to drive the propeller (rotor) through transmission to generate lift. The propellers used in traditional multi-rotor aircraft are generally fixed and locked to the output shaft end of the motor. In order to improve the convenience of use, most of the existing propellers for multi-rotor aircraft adopt a quick installation mechanism, which is detachably connected to the output shaft end of the corresponding motor. [0003] Existing propeller rapid installation mechanisms for multi-rotor aircraft generally include a fixed base fixed to the output shaft end of the motor and a connector detachably mounted on t...

AI Technical Summary

Problems solved by technology

Although the intervention of the quick installation mechanism can effectively realize the quick disassembly and assembly of the propeller, compared with the fixed locking method, its assembly stability is relatively low

In order to ensure the assembly of the propeller and the stability of its operation, the connecting parts are generally fixed and mounted on the fixed base by means of mounting. The corresponding clamping parts / clamping grooves fix the connecting parts, resulting in a relatively large volume and weight of the fixed base

After the propeller is disassembled, the fixed base with large volume and weight is still fixed on the output shaft end of the motor of the aircraft. , During transportation, etc., it is easy to cause damage to the output shaft of the motor
