Description

Technical Field

[0001] The utility model relates to the technical field of installation and connection of propellers of unmanned aerial vehicles, in particular to an installation structure of propellers of unmanned aerial vehicles. Background Art

[0002] With the rapid development of UAV technology, the application fields of UAVs have gradually expanded, from the initial military reconnaissance and strike to the later civil aerial photography, mapping, logistics and other fields. As one of the core components of UAVs, the stability and reliability of the installation structure of the propeller has a vital impact on the overall performance and safe flight of the UAV.

[0003] Traditional drone propeller installation structures usually use screw fixing or snap-on connection. Although these methods can meet the propeller installation requirements to a certain extent, there are still some problems in actual use. For example, the screw fixing method requires manual operation, the installation process is cumbersome and time-consuming, and it is easy for the propeller to be loosely installed or damaged due to improper operation; the snap-on connection method is easy to install, but during flight, especially in high-speed rotation or encountering harsh environments such as strong winds, the snap-on connection is prone to loosening or falling off, thus affecting the flight safety of the drone.

[0008] Preferably, an adjustment slot is provided at the top of the through slot, and the design of the adjustment slot makes the adjustment of the sliding magnetic plate more convenient, thereby improving the installation efficiency.

[0009] Preferably, a circular ring is fixedly mounted on the outer surface of the shaft rod, and a plurality of sets of limit pins are fixedly mounted on the outer surface of the top end of the circular ring. The limit pins can be used in conjunction with the limit grooves to effectively prevent the connecting block from loosening or shifting during flight, thereby enhancing the stability of the entire mounting structure.

[0010] Preferably, a plurality of groups of limiting grooves are provided on the outer surface of the bottom end of the connection block, and the plurality of groups of limiting grooves play a role of limiting connection.

[0011] Preferably, connecting rings are fixedly mounted on the outer surfaces of both sides of the connecting block, and threads are provided on the outer surfaces of the connecting rings.

[0014] It can be seen from the above technical solutions that this application has the following beneficial effects:

[0015] 1. The utility model greatly simplifies the installation steps by engaging the spring-driven telescopic pin with the fixed groove and using the movable plate with the sliding magnetic plate. The installer only needs to dock the connecting block with the shaft rod, adjust the position of the movable plate, and then slide the magnetic plate to fix it, thus completing the installation and improving the installation efficiency.

[0016] 2. The utility model ensures the installation accuracy of the propeller mounting structure through the precise engagement of the telescopic pin and the fixing slot, as well as the coordinated use of the movable plate and the through slot of the connecting block, the adjustment slot and the sliding magnetic plate. This structural design not only provides basic structural stability, but also further enhances the firmness of the connection through the magnetic force. This helps to reduce the risk of propeller loosening or falling off due to improper installation, and improves the flight safety of the drone. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] See also Figure 1-5 , an embodiment provided by the utility model:

[0025] A propeller mounting structure for a drone includes a motor 1, wherein a shaft 2 is connected to the top of the motor 1, and a plurality of connecting grooves are provided on the outer surface of the top of the shaft 2, a movable plate 211 is movably mounted on the inner wall of the plurality of connecting grooves, and a connecting buckle 212 is fixedly mounted on the outer surface of the movable plate 211, a plurality of grooves are provided on the outer surface of the shaft 2, and springs are mounted in the plurality of grooves, one end of the spring is connected to a telescopic pin 9, a connecting block 3 is movably mounted on the outer surface of the shaft 2, and a fixing groove is provided on the outer surface of the connecting block 3, a plurality of mounting grooves are provided on the outer surface of the connecting block 3, and a through groove is provided on one side of the plurality of mounting grooves, a sliding magnetic plate 312 is movably mounted in the through groove, and a propeller 4 is connected to the outer surface of the connecting block 3.

[0026] Furthermore, an adjustment slot 311 is provided at the top of the through slot, and the design of the adjustment slot 311 makes the adjustment of the sliding magnetic plate 312 more convenient, thereby improving the installation efficiency.

[0027] Furthermore, a circular ring 911 is fixedly installed on the outer surface of the shaft rod 2, and a plurality of sets of limit pins 7 are fixedly installed on the outer surface of the top end of the circular ring 911. The limit pins 7 can be used in conjunction with the limit grooves 8 to effectively prevent the connection block 3 from loosening or shifting during flight, thereby enhancing the stability of the entire installation structure.

[0028] Furthermore, a plurality of groups of limiting grooves 8 are provided on the outer surface of the bottom end of the connection block 3, and the plurality of groups of limiting grooves 8 play a role of limiting connection.

[0029] Furthermore, connecting rings 6 are fixedly installed on the outer surfaces of both sides of the connecting block 3, and the outer surfaces of the connecting rings 6 are provided with threads. A connecting cover 5 is movably installed on the outer surface of the connecting ring 6. The connecting cover 5 is rotatably connected to the connecting ring 6, so that the connecting cover 5 can protect the telescopic pin 9, and can prevent the telescopic pin 9 from being disturbed or damaged by external debris during flight, thereby ensuring that it can work normally when needed.

[0030] Furthermore, the outer surface of the connection cover 5 is serrated. The serrated design of the outer surface of the connection cover 5 increases the friction when holding, making the operation more stable and reducing accidents caused by hand slippage.

[0031] Furthermore, the outer surfaces of the plurality of limit pins 7 are wrapped with rubber, which has excellent elasticity and wear resistance. By wrapping the outer surfaces of the limit pins 7 with rubber, the friction and wear between the limit pins 7 and the limit grooves 8 can be effectively reduced. This can not only extend the service life of the limit pins 7 and the limit grooves 8, but also reduce the noise and vibration caused by friction, thereby improving the flight stability of the drone.

[0032] Working principle: When installing, first dock the connecting block 3 with the shaft 2. In this process, due to the action of the spring installed on the outer surface of the shaft 2, the telescopic pin 9 can shrink when squeezed, which is convenient for the initial sleeve connection between the connecting block 3 and the shaft 2. When the connecting block 3 and the shaft 2 move to the correct position, the telescopic pin 9 will pop out under the action of the restoring force of the spring and accurately engage with the fixing groove on the outer surface of the connecting block 3. This step ensures the initial fixation between the shaft 2 and the connecting block 3 and provides basic structural stability. Subsequently, the movable plate 211 at the top of the shaft 2 is adjusted to expand outward. These movable plates 211 cooperate with the through groove on the outer surface of the connecting block 3 through the connecting buckle 212, further enhancing the connection stability between the shaft 2 and the connecting block 3. Finally, by adjusting the adjusting groove 311 on the connecting block 3, the sliding magnetic plate 312 can be moved. When the sliding magnetic plate 312 passes through the inner wall of the connecting buckle 212, the movable plate 211 is firmly adsorbed on the connecting block 3 by magnetic force, thereby realizing the final fixation of the propeller installation structure.
