[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

Embodiment Construction
[0019] The present invention will be further described now in conjunction with accompanying drawing. These drawings are simplified schematic diagrams only to illustrate the basic structure of the present invention in a schematic way, so they only show the components relevant to the present invention.
[0020] like figure 1 , figure 2 Shown, a kind of folding propeller has left paddle 11, right paddle 12, upper paddle cover 21, lower paddle cover 22, left paddle 11, right paddle 12 are provided with mounting end, left paddle 11, right paddle The installation end of paddle 12 is sandwiched between upper paddle cover 21 and lower paddle cover 22, the installation end of left paddle 11 is hingedly connected with upper paddle cover 21 and lower paddle cover 22, and the installation end of right paddle 12 is connected with upper paddle cover. Cover 21 and lower paddle cover 22 are hingedly connected, and the middle part of upper paddle cover 21 and lower paddle cover 22 is respec...

The invention relates to a foldable propeller, which has a left blade, a right blade, an upper blade cover and a lower blade cover, the left blade and the right blade are provided with installation ends, and the installation ends of the left blade and the right blade are clamped on Between the upper paddle cover and the lower paddle cover, the installation end of the left paddle is hingedly connected with the upper paddle cover and the lower paddle cover, the installation end of the right paddle is hingedly connected with the upper paddle cover and the lower paddle cover, and the upper paddle cover and the lower paddle cover are hingedly connected. The middle part of the cover is respectively provided with a horizontal connecting rod, and the middle part of the horizontal connecting rod is provided with a motor shaft mounting hole. The manufacturing cost of the mold of the present invention is low. The propeller blades of the present invention can be folded, and the impact on the left and right propeller blades will not cause the motor shaft of the motor driving the propeller to be bent and damaged, thereby reducing maintenance costs caused by damage to other important components. At the same time, the folded propeller can also play a good role in protecting the left propeller blade and the right propeller blade during the handling process.
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 ...
