Description

Technical Field

[0001] The present application relates to the technical field of unmanned aerial vehicles (UAVs), and more specifically, to a UAV rotor mounting structure. Background Art

[0002] Unmanned aerial vehicle, or UAV for short, is an unmanned aircraft that is controlled by a radio remote control device or a self-contained program control device. In complex, harsh or dangerous scenarios, UAVs have demonstrated incomparable advantages over traditional manned aircraft and have become one of the important applications of modern technology.

[0003] In the construction of drones, rotors play a vital role. However, most drones on the market currently have rotors that are integrated with the drone's cantilever through a motor design. Although this design ensures flight stability to a certain extent, it brings some problems during the drone recovery process. When the drone completes its flight mission and needs to land for recovery, the rotors are easily deformed or damaged due to accidental collisions or improper operation. Once the rotor is damaged, professional technicians are required to repair it. However, due to the integrated design of the rotor and the cantilever, the damaged rotor is not easy to disassemble and replace. This not only increases the difficulty and cost of maintenance, but also prolongs the maintenance cycle of the drone, affecting its efficiency in being put into use again. In addition, the installation of the new rotor also faces considerable challenges. Due to the limitations of the integrated structure, the new rotor needs to be precisely aligned and fixed during the installation process, which not only requires a high level of technology, but also increases the risk during the installation process.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0021] Example:

[0022] See also Figure 1 , Figure 2 , Figure 3 , a UAV rotor mounting structure, including a frame 1 and a driving motor 3 installed at the cantilever end of the frame 1.

[0023] Among them, the frame 1 is the main structure of the drone, which carries all electronic equipment and mechanical components and provides support and protection for them.

[0024] Among them, the frame 1 is designed to be sturdy and lightweight to adapt to various flight environments and mission requirements; the cantilever end of the frame 1 is specially reinforced to ensure the stable installation of the drive motor 3; the cantilever end is made of high-strength material and can withstand the strong centrifugal force generated by the rotor 211 when rotating at high speed.

[0025] Among them, the driving motor 3 is the power source of the rotor 211, and its performance directly affects the flight effect of the UAV; and the driving motor 3 adopts a high-performance electric motor with the characteristics of high speed, large torque, and fast response speed.

[0026] Among them, the drive motor 3 is precisely installed at the cantilever end of the frame 1. In order to ensure the stability and transmission efficiency of the drive motor 3, high-precision positioning and fixing technology is adopted during the installation process; in addition, the output end of the drive motor 3 is tightly and fixedly connected to the rotor mounting mechanism 2 to ensure that the rotor 211 can rotate smoothly.

[0027] Among them, the frame 1 serves as the main skeleton of the UAV and bears the weight of the entire flight system. The drive motor 3 is the power core of the UAV. By receiving instructions from the flight control system, it can drive the rotor 211 to rotate, thereby overcoming the gravity of the UAV and allowing the frame 1 to take off and fly.

[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A UAV rotor mounting structure includes a rotor mounting mechanism 2 fixedly connected to the output end of a driving motor 3, and the rotor mounting mechanism 2 is composed of a rotor assembly 21, a mounting assembly 22 and a rubber gasket 23; the rotor assembly 21 includes two rotors 211 and a mounting tube 212; the mounting assembly 22 includes two fixing blocks 221, two channels I 222, two channels II 223, two limit grooves 224 and a fixing member 225; the fixing member 225 includes a threaded head 2251, a top cap 2252 and a threaded groove 2253.

[0029] The rotor installation mechanism 2 is composed of a rotor assembly 21, a mounting assembly 22 and a rubber gasket 23, and adopts a modular design, which makes the installation and disassembly process of the rotor 211 simpler and improves the convenience of maintenance.

[0030] Among them, the design of the rotor assembly 21 is particularly critical. The rotor assembly 21 is mainly composed of two rotors 211 and a mounting tube 212. These two parts work together to ensure the stable flight of the UAV; the opposite ends of the two rotors 211 are fixedly connected to the two sides of the outer wall of the mounting tube 212, and the mounting tube 212 is fixed to the output end of the drive motor 3 by the mounting assembly 22, so that the rotor 211 can maintain balance and stability during rotation; the mounting tube 212 serves as a bridge connecting the rotor 211 and the drive motor 3, and its design is also crucial; the mounting tube 212 is made of a mold. This process ensures the accuracy of its size and shape, making the installation with the output end of the drive motor 3 more convenient and efficient.

[0031] Among them, the installation component 22 is undoubtedly the core element to ensure that the rotor component 21 is stably fixed on the output end of the drive motor 3, and its design details play a vital role in the overall stability and safety of the flight system; two fixing blocks 221 are set on both sides of the outer wall of the output end of the drive motor 3, which serve as a solid foundation for the installation component 22 and provide solid support and accurate positioning for subsequent installation operations; at the same time, the inner wall design of the installation tube 212 is also ingenious, and the two vertical channels Ⅰ222 on both sides and the two horizontal channels Ⅱ223 and the limit groove 224 together constitute a smooth and precise fixing path; this design allows the fixing block 221 to easily and accurately pass through channels Ⅰ222 and channels Ⅱ223 Finally, it is firmly inserted into the limiting groove 224 to form an indestructible clamping connection; during the fixing process, the clamping connection between the fixing block 221 and the limiting groove 224 is not only easy to operate, but also firm and reliable; this connection method can effectively resist the strong vibration and impact generated during the flight, ensuring that the rotor assembly 21 always maintains a stable working state; in addition, the introduction of the fixing piece 225 is icing on the cake; it can further fix the fixing block 221 that has been firmly fixed in the limiting groove 224, thereby ensuring that the connection between the mounting tube 212 and the output end of the drive motor 3 achieves unparalleled stability; this design not only improves the flight performance and safety of the UAV, but also provides a solid technical guarantee for its wide application and promotion.

[0032] Among them, the fixing piece 225 is one of the key components connecting the output end of the drive motor 3 and the mounting tube 212; the threaded head 2251 is the bottom connecting part of the fixing piece 225, and its bottom end is welded to the top of the output end of the drive motor 3; this connection method ensures the connectivity between the fixing piece 225 and the drive motor 3, so that the entire rotor mounting structure is not easy to loosen or fall off during flight; at the same time, the top of the threaded head 2251 extends out of the top of the mounting tube 212, which provides convenience for subsequent fixing operations; during the installation process, the threaded head 2251 can be threadedly connected with the threaded groove 2253 opened at the bottom of the top cap 2252, so as to achieve a tight fixation between the fixing piece 225 and the mounting tube 212; by rotating the top cap 2252, the inner wall of the threaded groove 2253 can be threadedly connected with the outer wall of the threaded head 2251, so as to achieve the fixing effect of the fixing piece 225 on the mounting tube 212; this threaded connection method has the advantages of simplicity, reliability, and detachability, making the replacement and maintenance of the rotor assembly 21 more convenient and quick.

[0033] Among them, the rubber gasket 23 is arranged between the installation tube 212 and the top cap 2252; and the addition of the rubber gasket 23 not only enhances the firmness of the connection, but also optimizes the sealing performance of the overall structure, effectively preventing dust, moisture and other external impurities from entering the connection part, so that it will not rust.

[0034] Among them, after the connection design between the mounting assembly 22 and the output end of the drive motor 3 was optimized, we further optimized the structure of the rotor assembly 21. Specifically, the mounting cylinder 212 and the two rotors 211 were formed by an integral casting method; this integral casting method not only simplifies the production process and improves production efficiency, but more importantly, it greatly enhances the connection strength between the mounting cylinder 212 and the rotor 211. Through integral casting, the connection between the mounting cylinder 212 and the rotor 211 is seamless, effectively avoiding flight safety hazards caused by loose or broken connections; in addition, the two rotors 211 are designed to be inclined. This inclined design not only optimizes the aerodynamic performance of the rotor 211, making the UAV more stable during flight, but also improves the controllability of the UAV, allowing the operator to more flexibly control the flight attitude and trajectory of the UAV.

[0035] The working principle of the UAV rotor installation structure is as follows: when in use, the user sets the installation tube 212 on the outer wall of the output end of the driving motor 3, and at the same time, the two fixing blocks 221 first pass through the two channels I 222 from one end to the other end, and then rotate the installation tube 212 so that the two fixing blocks 221 pass through the two channels II 223 from one end to the other end, and then press the installation tube 212 to make the two fixing blocks 221 enter the two limit grooves 224. At this time, the thread head 2251 extends out of the top of the installation tube 212 and is aligned with the thread at the bottom of the top cap 2252. The groove 2253 is threadedly connected, thereby achieving a tight fixation between the mounting tube 212 and the driving motor 3; this connection method is not only firm and reliable, but also detachable, which is convenient for the replacement and maintenance of the rotor assembly 21; when working, the driving motor 3 starts and drives the mounting tube 212 and the rotor 211 to rotate. Due to the special design of the rotor 211, they can generate sufficient lift to support the flight of the UAV. At the same time, by adjusting the motor speed and the inclination angle of the rotor, the flight attitude, speed and direction of the UAV can be controlled.

[0036] It should be noted that the specific model and specifications of the drive motor 3 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0037] The power supply and principle of the driving motor 3 are clear to those skilled in the art and will not be described in detail here.

[0038] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
