Problems solved by technology

[0003] In the prior art, the propeller and the motor are usually connected by a nut and a lock, so that the propeller is prone to break away from the motor during the acceleration and deceleration process of the motor, and the screw thread direction between the propeller and the motor and the direction of rotation of the motor On the contrary, after the motor has been working for a period of time, the thread fit between the propeller and the motor is very tight, which makes it difficult to disassemble the propeller and the motor, and cannot be disassembled quickly, thus reducing the portability of the aircraft.

Embodiment 1

[0057] figure 1 A structural schematic diagram of a locking mechanism of a propeller 1 provided for an embodiment of the present invention Figure 1 ; figure 2 It is a schematic diagram of an exploded structure of a locking mechanism of a propeller provided by an embodiment of the present invention; image 3 A structural schematic diagram of a locking mechanism of a propeller 1 provided for an embodiment of the present invention Figure II ; Figure 4 A schematic cross-sectional view of a locking mechanism of a propeller 1 provided for an embodiment of the present invention Figure 1 ; refer to attached Figure 1-4 It can be seen that this embodiment provides a locking mechanism for the propeller 1 , which is used for detachably locking the propeller 1 on the motor 2 . The propeller 1 includes a first body, and the motor 2 includes a second body. The locking mechanism includes a pressing piece 3 , a first elastic piece 5 , a locking piece 4 , and a second elastic piece ...

Embodiment 2

[0067] On the basis of the first embodiment above, continue to refer to the appended Figure 1-4 It can be seen that the specific structure of the pressing part 3 is not limited in this embodiment, and those skilled in the art can set it according to specific design requirements. More preferably, the pressing part 3 is configured to include: the execution end 301 and the transmission end 302 . The actuating end 301 is used for abutting against the first elastic member 5 , and the driving end 302 is used for directly or indirectly connecting with the locking member 4 .

[0068] When the execution end 301 is pressed, the execution end 301 moves in a direction close to the locking member 4, so that the locking member 4 is in an unlocked state; when the first elastic member 5 provides an elastic restoring force to the pressing member 3, the execution end 301 Move in a direction away from the locking member 4, so that the locking member 4 is in a locked state.

Embodiment 3

[0071] Figure 5 A schematic cross-sectional view of a locking mechanism of a propeller 1 provided for an embodiment of the present invention Figure II ; Figure 6 for image 3 A-A to the sectional schematic diagram; On the basis of the above-mentioned embodiment two, continue to refer to the appended Figure 1-6 It can be seen that, further, an accommodation space 8 for the locking member 4 to slide along the second direction is formed between the transmission end 302 and the first body or between the transmission end 302 and the second body.

[0072] Since the locking member 4 can slide along the second direction, in order to realize the sliding operation of the locking member 4, an accommodating space 8 is provided between the transmission end 302 and the first body or between the transmission end 302 and the second body. The accommodating space 8 is used to realize the sliding operation of the locking member 4 in the second direction, and limit the extent of the slidin...

Abstract

A propeller (1) comprising a body, the motor (2) comprising a second body, the locking mechanism comprising a pressing member (3) for passing through a propeller (3), a propeller, a motor, a power unit, and an unmanned aerial vehicle, (3); a locking member (3) which is in contact with the pressing member (3) for providing an elastic restoring force to the pressing member (3); a locking member (4) (6) is in direct contact with the pressing member (3); the locking member is slidable in a second direction different from the first direction; the second elastic member (6) is in contact with the locking member (4) for providing the elastic restoring force A locking member (4) for engaging with the other of the main body and the second body; when the pressing member (4) is mounted on the main body or the second body, 3), the pressing member (3) is driven to slide the locking member (4) so that the locking member (4) is in the unlocked state.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a locking mechanism for a propeller, a propeller, a motor, a power assembly and an unmanned aerial vehicle. Background technique [0002] With the continuous development and progress of science, the development of aircraft technology is becoming more and more mature. With the continuous increase of user needs, the requirements for the stability, reliability and convenience of aircraft use are also getting higher and higher. For aircraft, the propeller It is an important part of the aircraft. Usually, the propeller on the aircraft needs to be connected with the motor. The reliability of the connection between them is particularly important. [0003] In the prior art, the propeller and the motor are usually connected by a nut and a lock, so that the propeller is prone to break away from the motor during the acceleration and deceleration process of the motor, and the screw thread ...
