Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a quick-release propeller mount for UAVs. Background Technology

[0002] In recent years, drone technology has developed rapidly and has been widely used in many fields such as logistics, aerial photography, surveying and mapping, and emergency rescue. With the continuous expansion and deepening of application scenarios, higher requirements are being placed on the performance, reliability, and ease of use of drones. Among these, the assembly efficiency and connection stability between the drone's propellers and motors directly affect the overall performance and operational efficiency of the drone.

[0003] As is well known, during drone flight, the propeller blades are the key component generating lift, while the motor provides power for the blades' rotation. Therefore, the connection between the propeller blades and the motor must be robust and reliable to ensure that the blades do not loosen or detach under high-speed rotation and complex flight environments, thus guaranteeing flight safety. Furthermore, to adapt to different flight missions and operating environments, it is sometimes necessary to quickly change propeller blades of different specifications, which requires the assembly process of the propeller blades and motor to be efficient and convenient.

[0004] However, most drones on the market still use the traditional bolt connection method to fix the propellers to the motor. On the one hand, this assembly method is relatively cumbersome. When installing or removing the propellers, multiple bolts need to be tightened or loosened one by one, which consumes a lot of time and manpower, resulting in low work efficiency and high labor costs. On the other hand, since the bolts are tightened manually, the tightness of multiple bolts may be uneven, which will lead to an unsatisfactory connection between the propellers and the motor. This will cause the propellers to wobble during rotation, which will not only affect the flight performance of the drone, but may also cause safety accidents.

[0005] In view of the above, this utility model is hereby proposed. Summary of the Invention

[0006] To overcome the above-mentioned defects, this utility model provides a quick-release propeller mount for drones. On the one hand, it has a simple and reasonable structure, is easy to process and manufacture, and has a low manufacturing cost. On the other hand, it can quickly, conveniently and reliably assemble drone propellers and drone motors together, which not only improves the efficiency of drone assembly / disassembly, but also improves the structural stability of the drone after assembly, ensuring the overall performance of the drone.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: a quick-release propeller mount for a drone, comprising a first quick-release assembly for connecting to a drone propeller blade, a second quick-release assembly for connecting to a drone motor, and an elastic component. The first quick-release assembly has a plurality of hook portions arranged in a ring on the side facing away from the drone propeller blade. The second quick-release assembly has a plurality of slot portions and a plurality of through portions on the side facing away from the drone motor, and the slot portions and through portions are alternately arranged in a ring. When an external force is applied to make the hook portions engage with the slot portions one by one, the first quick-release assembly and the second quick-release assembly can be snapped together. When an external force is applied to make the hook portions engage with the through portions one by one, the first quick-release assembly and the second quick-release assembly can be separated. The elastic component is disposed between the first quick-release assembly and the second quick-release assembly and can apply elastic pressure to the second quick-release assembly snapped together with the first quick-release assembly, so that the second quick-release assembly is securely snapped together with the first quick-release assembly.

In addition, each connecting block is provided with a connecting hole for connection with countersunk bolts. Furthermore, a plurality of hooks are integrally connected to the ends of the plurality of connecting blocks facing away from the propeller hub.

[0012] As a further improvement of this utility model, in the shaft flange, one end of the shaft portion extends out of the flange portion to engage with the mounting hole groove on the propeller hub.

[0013] As a further improvement of this utility model, the second quick-release assembly is provided with a flange that is detachably and lockably connected to the UAV motor and a functional component that is fixedly connected to one side of the flange. The functional component is a ring structure and can be tightly fitted onto the shaft. The outer periphery of the functional component is provided with a plurality of slots and a plurality of through parts. When the multiple hooks correspond one-to-one with the multiple through parts, the flange and the functional components can be movably inserted into or detached from the outer sleeve; and when the multiple hooks are respectively engaged with the multiple slots, the flange and the functional components can be positioned in the outer sleeve.

[0014] As a further improvement of this utility model, the slot portion adopts a groove structure with openings on the outer edge of the functional component and on the side of the functional component facing the flange, and the cross-sectional shape of the slot portion matches the shape of the hook portion.

[0016] As a further improvement of this utility model, the pressing member is composed of an annular plate base and a bushing coaxial with and integrally connected to the plate base. A plurality of clearance holes are arranged in a ring on the outer edge of the plate base, and a limiting part for stopping and limiting the bushing is protruding on the outer surface of the shaft.

[0020] The preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Example:

[0022] Please see the appendix Figure 1 As shown, this embodiment provides a quick-release propeller mount 3 for drones, used to quickly, conveniently, and reliably assemble the drone propeller 1 and the drone motor 2 together. Both the drone propeller 1 and the drone motor 2 adopt conventional structures in the current drone technology field, and since they are not covered by this application, they are only briefly described here: Please refer to the attached document. Figure 2 and 3 As shown, the drone propeller 1 has a hub 10 and two blades 11 fixedly connected to opposite sides of the hub 10. The hub 10 is used to connect to the drone motor 2. Combined with the drone quick-release propeller mount 3 provided in this application, the hub 10 is connected to the drone motor 2 through the drone quick-release propeller mount 3, and the back of the hub 10 is recessed with a mounting slot 100 that does not penetrate the front of the hub 10. The drone motor 2 can be, but is not limited to, an external rotor brushless motor; the specific motor type can be determined according to product design requirements.

[0023] The following is a detailed description of the specific structure of the UAV quick-release propeller mount 3 described in this embodiment.

[0024] Please see the appendix Figure 1 Appendix Figure 4 To be continued Figure 10 As shown, the drone quick-release propeller mount 3 includes a first quick-release assembly 31 for fixed connection with the propeller hub 10 of the drone propeller blade 1, a second quick-release assembly 32 for fixed connection with the power output shaft (such as the rotor of a brushless motor) of the drone motor 2, and an elastic assembly 33. The first quick-release assembly 31 has a plurality of hook portions 310 arranged in a ring on the side facing away from the propeller hub 10. The second quick-release assembly 32 has a plurality of slot portions 320 and a plurality of through portions 321 arranged alternately in a ring on the side facing away from the drone motor 2. When an external force is applied to engage the plurality of hook portions 310 with the plurality of slot portions 320 one by one... This allows the first quick-release component 31 and the second quick-release component 32 to be snapped together; and when an external force is applied to make the multiple hooks 310 correspond one-to-one with the multiple through parts 321, the first quick-release component 31 and the second quick-release component 32 can be separated; the elastic component 33 is disposed between the first quick-release component 31 and the second quick-release component 32, and can apply elastic pressure to the second quick-release component 32 which is snapped together with the first quick-release component 31, so that the second quick-release component 32 is securely snapped together with the first quick-release component 31, thereby enhancing the reliability / stability of the snap-connection between the second quick-release component 32 and the first quick-release component 31.

[0025] Furthermore, in this embodiment, the preferred implementation structure of the first quick-release component 31 is as follows: Please refer to the appendix. Figure 4 To be continued Figure 8 As shown, the first quick-release assembly 31 includes an outer sleeve 311, a receiving component 312, and a shaft flange 313. The outer sleeve 311 and the receiving component 312 are hollow circular sleeve structures with openings on both axial sides. One axial side of the outer sleeve 311 is detachably and securely connected to the rotor hub 10 of the UAV propeller 1 via bolts 34. The receiving component 312 is coaxially and fixedly inserted into the outer sleeve 311. Multiple radially inwardly extending members are arranged in a ring on the axial side of the receiving component 312 facing away from the UAV propeller 1 (specifically, the rotor hub 10). The extended hook portions 310, as understood, are all located close to the other axial side of the outer sleeve 311; the shaft flange 313 is composed of a flange portion 3130 and a shaft portion 3131 coaxially and integrally connected (this is known technology), the shaft flange 313 is coaxially inserted into the outer sleeve 311, and the flange portion 3130 of the shaft flange 313 is also fixedly connected to one axial side of the outer sleeve 311 by a plurality of countersunk bolts, and the receiving member 312 and the plurality of hook portions 310 thereon are respectively surrounding the shaft portion 3131 of the shaft flange 313. It is understood that the outer sleeve 311 mainly serves to connect with the propeller hub 10, and to receive the receiving member 312 and the shaft flange 313, etc.; the receiving member 312 mainly serves to receive the hook portions 310, etc.; and the shaft flange 313 mainly serves to receive the second quick-release assembly 32 and the elastic assembly 33, etc., described below.

[0026] Furthermore, in this embodiment, the receiving member 312 is preferably integrally connected with the plurality of hook portions 310, and the plurality of hook portions 310 are preferably designed as arc-shaped block structures according to product design requirements, as shown in the appendix. Figure 7 As shown.

[0027] Furthermore, in this embodiment, the specific implementation structure for achieving coaxiality and fixed insertion of the receiving member 312 into the outer sleeve 311 is as follows: Please refer to the appendix. Figure 5 and attached Figure 8As shown, a plurality of connecting blocks 314 are integrally protruding on the inner wall of the receiving member 312. The plurality of connecting blocks 314 are arranged in a ring at intervals, and the opposite ends of each connecting block 314 extend to be flush with the axial sides of the receiving member 312. Furthermore, each connecting block 314 is provided with a connecting hole 3140 for connecting with a countersunk bolt 35. It can be understood that by passing the countersunk bolt 35 through the outer sleeve 311 and tightly inserting or screwing it into the connecting hole 3140, the receiving member 312 and the connecting blocks 314 and the hook portion 310 thereon can be fixed in the outer sleeve 311.

[0028] In addition, based on the configuration of the connecting block 314, the plurality of hook portions 310 are respectively integrally connected to the ends of the plurality of connecting blocks 314 facing away from the propeller hub 10.

[0029] Furthermore, in this embodiment, one end of the shaft portion 3131 in the shaft flange 313 extends beyond the flange portion 3130 (see attached drawing). Figure 4 and attached Figure 6 As shown, the shaft portion 3131 is designed to engage with the mounting hole 100 on the propeller hub 10. It is understood that one end of the shaft portion 3131 can be movably or slightly tightly inserted into the mounting hole 100. The engagement between the shaft portion 3131 and the mounting hole 100 is primarily for the purpose of quickly aligning and assembling the propeller hub 10 with the first quick-release assembly 31, serving a guiding function.

[0030] Furthermore, in this embodiment, based on the above description of the structure of the first quick-release component 31, the preferred implementation structure of the second quick-release component 32 is as follows: Please refer to the appendix. Figure 5 Appendix Figure 9 and attached Figure 10As shown, the second quick-release assembly 32 is provided with a flange 322 that is detachably and lockably connected to the power output shaft of the UAV motor 2, and a functional component 323 that is fixedly connected to one side of the flange 322 via a hollow shaft (not shown in the figure, but does not affect the technical understanding). The functional component 323 is a ring structure and can be tightly fitted (specifically, slightly tightly fitted) onto the shaft portion 3131. The outer periphery of the functional component 323 is provided with a plurality of slot portions 320 and a plurality of through portions 321. When the plurality of hook portions 310 correspond one-to-one with the plurality of through portions 321, the flange 322 together with the functional component 323 can be movably inserted into or detached from the outer sleeve 311. When the plurality of hook portions 310 are respectively connected to the plurality of slot portions 320, the flange 322 together with the functional component 323 can be positioned in the outer sleeve 311. Understandably, when the second quick-release assembly 32 is positioned and connected to the first quick-release assembly 31, the power output from the power output shaft of the UAV motor 2 can be transmitted to the UAV propeller 1 through the flange 322, the functional component 323, the receiving component 312 and the outer sleeve 311 in sequence, so as to drive the UAV propeller 1 to rotate.

[0031] Furthermore, in this embodiment, the preferred implementation structures of the slot portion 320 and the through portion 321 are as follows: Please refer to the appendix. Figure 9 and 10 As shown, the slot portion 320 adopts a groove structure with openings on the outer edge of the functional component 323 and on the side of the functional component 323 facing the flange 322, and the cross-sectional shape of the slot portion 320 matches the shape of the hook portion 310; Note: If the axial direction of the shaft portion 3131 is defined as vertical, the "cross-sectional shape of the slot portion 320" mentioned above refers to the horizontal cross-sectional shape of the slot portion 320. The through portion 321 adopts an arc-shaped hole structure that passes through both sides of the functional component 323 along its axial direction, and the center of the circle containing the through portion 321 is located on the extended line of the radius of the functional component 323.

[0032] Furthermore, in this embodiment, the preferred implementation structure of the elastic component 33 is as follows: Please refer to the appendix. Figure 9 As shown, the elastic component 33 is provided with a spring 330 and a pressing member 331. The spring 330 and the pressing member 331 are respectively movably sleeved on the shaft portion 3131, and the two ends of the spring 330 elastically abut against the flange portion 3130 and the pressing member 331 respectively. The side of the pressing member 331 facing away from the spring 330 can be fitted and connected to the side of the functional component 323 facing away from the flange 322.

[0033] For further details, please refer to the appendix. Figure 9 and attached Figure 10 As shown, the pressing member 331 is composed of an annular plate base 3310 and a bushing 3311 coaxial with and integrally connected to the plate base 3310. The outer edge of the plate base 3310 is provided with a plurality of clearance slots 3312 for avoiding the connecting block 314. The outer surface of the shaft portion 3131 is provided with a limiting portion 3132 for stopping and limiting the bushing 3311.

[0034] Based on the above detailed structural description of the UAV quick-release propeller mount 3 in this embodiment, the method of using the UAV quick-release propeller mount 3 is as follows: S1: First, insert one end of the shaft portion 3131 of the shaft flange 313 into the mounting hole slot 100 on the propeller hub 10. After adjusting and aligning the outer sleeve 311 with the propeller hub 10, use the bolts 34 to lock the outer sleeve 311 and the propeller hub 10 together. Also, lock the flange 322 with the power output shaft of the UAV motor 2 together. S2: The spring 330 and the pressing member 331 are sequentially fitted onto the shaft portion 3131 of the shaft flange 313, while the multiple clearance slots 3312 on the pressing member 331 are respectively connected to the multiple connecting blocks 314 one by one. S3: First, align the multiple connecting blocks 314 with the multiple through portions 321 one by one, and align the shaft portion 3131 with the functional component 323, and then assemble the first quick-release assembly 31 and the second quick-release assembly 32 together; Note: The above assembly can be performed by the operator using both hands, or the second quick-release assembly 32 can be fixed by a fixing fixture, and the operator can then operate only the first quick-release assembly 31. After the multiple hook portions 310 extend out of the multiple through portions 321 (at which point the shaft portion 3131 has docked with the functional component 323, indicating that the shaft portion 3131 and the functional component 323 are in a slightly tight fit, that is, when a large external force is applied, the relative position between the shaft portion 3131 and the functional component 323 can be adjusted), rotate the first quick-release assembly 31 so that the multiple hook portions 310 correspond one-to-one with the multiple slot portions 320; then pull the first quick-release assembly 31 in the opposite direction (so that the first quick-release assembly 31 moves away from the second quick-release assembly 32) so that the multiple hook portions 310 are respectively engaged and positioned one-to-one with the multiple slot portions 320. After the hook portion 310 is engaged and positioned with the slot portion 320, the spring 330 (a high-elasticity compression spring) is in a compressed state and can apply a set elastic pressure to the second quick-release assembly 32 to enhance the stability of the snap-fit ​​connection between the second quick-release assembly 32 and the first quick-release assembly 31. It is understood that the power output from the power output shaft of the drone motor 2 can be transmitted sequentially through the flange 322, the functional component 323, the receiving component 312, and the outer casing 311 to the drone propeller 1, thereby driving the drone propeller 1 to rotate.

[0035] In addition, it is understandable that when it is necessary to separate the first quick-release component 31 from the second quick-release component 32, it is only necessary to press down to separate the hook part 310 from the slot part 320 and rotate to make the hook part 310 correspond to the through part 321, so as to release the locking connection between the first quick-release component 31 and the second quick-release component 32 and separate the two.

[0036] In summary, the quick-release propeller mount for drones described in this utility model is not only simple and reasonable in structure, easy to process and manufacture, and low in manufacturing cost; it also enables the rapid, convenient and reliable assembly of drone propellers and drone motors, improving the efficiency of drone assembly / disassembly while enhancing the structural stability of the drone after assembly, thereby ensuring the overall performance of the drone.

[0037] Finally, the prefixes "first," "second," etc., in the component names in this specification (such as first quick-release assembly, second quick-release assembly, etc.) are only for clarity of description and are not intended to limit the scope of this utility model patent.
