[0002] The propeller of the existing multi-axis aircraft is a two-blade propeller. The current manufacturing process is to form the two-blade propeller in one piece. The integral two-blade propeller has a heavy structure and high manufacturing cost.
When a multi-axis aircraft uses an integrated two-bladed propeller, in the event of an accident such as a crash, once one of the two-bladed propellers is damaged, the entire two-bladed propeller needs to be replaced. At the same time, the two-bladed propeller and the motor are rigidly connected. After being hit, it is easy to damage the motor rigidly connected to the paddle
The disadvantages of the existing two-blade integrated propeller are: heavy weight, high cost of use and easy damage to associated parts

Abstract

The invention relates to a foldable propeller. The foldable propeller is provided with a left paddle blade, a right paddle blade, an upper paddle cover and a lower paddle cover, wherein mounting ends are respectively mounted on the left paddle blade and the right paddle blade, the mounting ends of the left paddle blade and the right paddle blade are clamped between the upper paddle cover and the lower paddle cover, the mounting end of the left paddle blade is connected with the upper paddle cover and the lower paddle cover in a hinge manner, the mounting end of the right paddle blade is connected with the upper paddle cover and the lower paddle cover in a hinge manner, horizontal connecting rods are respectively arranged at the middle parts of the upper paddle cover and the lower paddle cover, and motor shaft mounting holes are formed in the middle parts of the horizontal connecting rods. The foldable propeller has the advantage of low manufacturing cost of moulds. The paddle blades of the foldable propeller can be folded, a motor shaft of a motor for driving the propeller is not bent and damaged under the impact of the left paddle blade and the right paddle blade, and the maintenance cost generated by the damage of other important parts is reduced. Simultaneously, the folded propeller can be used for protecting the left paddle blade and the right paddle blade well during carrying.

Description

technical field [0001] The invention relates to a folding propeller. Background technique [0002] The propeller of the existing multi-axis aircraft is a double-blade propeller. The current manufacturing process is to form the two-blade propeller in one piece. The structure of the integrated two-blade propeller is heavy and the manufacturing cost is relatively high. When a multi-axis aircraft uses an integrated two-bladed propeller, in the event of an accident such as a crash, once one of the two-bladed propellers is damaged, the entire two-bladed propeller needs to be replaced. At the same time, the two-bladed propeller and the motor are rigidly connected. After being hit, it is easy to damage the motor rigidly connected with the paddle. The disadvantages of the existing two-blade integrated propeller are: heavy weight, high use cost and easy damage to associated parts. Contents of the invention [0003] The technical problem to be solved by the present invention is to ...
