Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) servo motor installation technology, specifically, to a servo motor installation mechanism for UAVs. Background Technology

[0002] The servo mounting mechanism of a drone refers to the general term for the mechanical components used to fix and support the servo motor and accurately transmit its output motion to the drone's control surface.

[0003] The existing patent, CN223200315U, entitled "A Servo Mounting Structure for Unmanned Aerial Vehicles," focuses on fixing the servo to the wing skin using a mounting plate and fasteners. The mounting plate's outer surface is designed with an aerodynamic shape, directly transferring the servo load to a localized area of ​​the wing skin. While this design utilizes the skin as a support structure to reduce costs, it may lead to skin fatigue and deformation over long-term use, posing a risk, especially for lightweight, thin-skinned UAVs. Its single load path means that concentrated stress during high-intensity maneuvers or encounters with airflow impacts can accelerate loosening or damage at connection points. The direct connection between the mounting plate and the wing skin also limits its adaptability. Changes to the wing structure or servo model may necessitate replacing the entire mounting plate. Furthermore, servo maintenance is hampered by limited operating space due to the wing's internal layout. Utility Model Content

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0019] Example like Figures 1-8 As shown, a servo mounting mechanism for a drone includes a drone body 100, which is composed of a main support 101 and four wing support bodies 104. The four wing support bodies 104 are detachably mounted at the four corners of the drone body 100. A wing body 105 is mounted on the top of the wing support body 104. A servo mounting bracket 200 is provided at the bottom of the drone body 100 for mounting a servo body 218. The servo mounting bracket 200 is composed of a central mounting frame 210, four connecting arms 220, and four wing connecting brackets 230. The number of connecting arms 220 and wing connecting brackets 230 is equal to the number of wing support bodies 104. The central mounting frame 210 is located at the bottom of the drone body 100 for fixing the servo body 218. The wing connecting brackets 230 are sleeved on the outer circumferential surface of the wing support bodies 104 for connecting with the wing support bodies 104. The connecting arms 220 are simultaneously connected to the central mounting frame 210 and the wing connecting brackets 230. The servo mounting bracket 200 is located at the bottom of the UAV body 100. The UAV body 100 consists of a main support 101 and four openable wing support bodies 104. Wing bodies 105 are mounted on the top of the wing support bodies 104. The servo mounting bracket 200 consists of a central mounting frame 210 located at the center of the bottom of the UAV, four connecting arms 220 corresponding to the wing supports, and four wing connecting brackets 230 corresponding to the wing supports. The central mounting frame 210 is used to centrally and securely mount multiple servo bodies 218. The wing connecting brackets 230 are fitted onto the outer circumference of their respective wing support bodies 104 by means of a sleeve, thereby suspending the entire mounting mechanism on the UAV body. The two ends of the connecting arms 220 are rigidly connected to the central mounting frame 210 and the wing connecting brackets 230, respectively, thereby distributing the load generated by the central mounting frame 210 to each wing support through multiple paths.

[0020] The wing connecting bracket 230 consists of a right-angle connecting bracket 232, a side connecting plate 233, and a top connecting plate 234. The side connecting plate 233 is bolted to one side of the right-angle connecting bracket 232, and the top connecting plate 234 is fixedly connected to the top of both the right-angle connecting bracket 232 and the side connecting plate 233.

[0021] The wing connecting bracket 230 is composed of a right-angle connecting frame 232, a side connecting plate 233, and a top connecting plate 234. The right-angle connecting frame 232 is the main frame of the wing connecting bracket 230. Its "L"-shaped design can fit well with the corner of the wing bracket body 104. The side connecting plate 233 is fastened to one side of the right-angle connecting frame 232 by bolts, forming a clamping space for accommodating the wing bracket. The top connecting plate 234 spans across and is fixedly connected to the top of the right-angle connecting frame 232 and the side connecting plate 233, enhancing the torsional rigidity of the entire assembly.

[0022] The top of the top connecting plate 234 is provided with two straight groove-shaped adjustment slots 235. The connecting bolts 224 of the top connecting plate 234, the side connecting plate 233, and the right-angle connecting bracket 232 are adjusted for locking position through the adjustment slots 235.

[0023] Two straight-groove-shaped adjustment slots 235 are provided on the top of the top connecting plate 234 for fixing the connecting bolts 224 of the top connecting plate 234 to the side connecting plate 233 and the right-angle connecting bracket 232. The threaded part of the connecting bolt 224 can pass through these adjustment slots 235. During the initial installation, the bolts do not need to be fully tightened. At this time, the top connecting plate 234 can slide relative to the components below, thereby changing the effective inner diameter of the entire clamping structure, which is convenient for fitting onto the wing bracket body 104. After the position is adjusted to the optimal position, the connecting bolts 224 are tightened. The bolt head and nut will firmly press the top connecting plate 234, achieving the final locking and fixing. This allows wing connecting brackets of the same specification to be adapted to wing brackets that are slightly different due to manufacturing tolerances or wear, improving the versatility and ease of assembly of the installation mechanism.

[0024] The central mounting frame 210 consists of a main mounting frame 211 and a fixing frame 219. The main mounting frame 211 is located at the bottom of the main support 101. Several first studs 212 are fixedly connected to the top of the main mounting frame 211. The fixing frame 219 is connected to the main mounting frame 211 by bolts to the first studs 212. At least two servo mounts 216 are provided at the bottom of the mounting bracket 219, and the servo body 218 is slidably mounted inside the servo mount 216.

[0025] The center mounting bracket 210 is composed of a main mounting bracket 211 and a fixed bracket 219. The main mounting bracket 211 is directly connected to the bottom of the UAV main body support 101, and several first studs 212 are welded to its top. The fixed bracket 219 is installed below the main mounting bracket 211 by bolts to these first studs 212. The fixed bracket 219 is used to support the servo motors. At least two servo motor placement brackets 216 are provided at the bottom of the fixed bracket 219. The servo motor placement bracket 216 is a slot-shaped structure for accommodating the servo motor body 218. The servo motor body 218 is initially inserted into the servo motor placement bracket 216 by sliding assembly, which facilitates its maintenance or replacement later.

[0026] The servo mounting bracket 216 has several equally spaced second studs 217 on both sides. The second studs 217 have threaded grooves that penetrate the fixing bracket 219. The servo body 218 is fixed by bolts threadedly connecting to the threaded grooves.

[0027] Several equally spaced second studs 217 are provided on both sides of the servo mounting bracket 216. The second studs 217 have threaded grooves machined inside, which extend upward through the entire mounting bracket 219. After the servo body 218 is slid into the servo mounting bracket 216, fixing bolts are used to pass through the mounting hole of the servo itself from above and screwed into the threaded groove of the second stud 217. By tightening these bolts, the servo body 218 can be firmly pressed and fixed in the servo mounting bracket 216, ensuring that the servo will not shake or shift in any direction.

[0028] The connecting arm 220 is composed of a connecting support arm 221, which is located between the main mounting frame 211 and the right-angle connecting frame 232 and is interconnected with the main mounting frame 211 and the right-angle connecting frame 232.

[0029] The connecting arm 220 consists of a connecting support arm 221. The connecting support arm 221 is made of aluminum alloy or carbon fiber. The connecting support arm 221 is set in the space between the main mounting frame 211 and the right-angle connecting frame 232. Both ends are mechanically connected to these two components respectively. The load of the servo motor body 218 located in the center is transferred and distributed to the wing connecting bracket 230 located on the periphery and stably connected to the wing bracket, so as to prevent the central mounting frame from being deformed or vibrated too much due to the weight of the servo motor when the UAV is maneuvering.

[0030] The main mounting frame 211 is located on the axis of the wing support body 104 and has a number of fixing seats 213 equal to the number of fixing seats 213. The fixing seats 213 are equipped with connecting nuts 215. The connecting arm 221 is located on one side of the main mounting frame 211 and is equipped with fixing nuts 222. The connecting nuts 215 and fixing nuts 222 are threaded together by a long screw 223.

[0031] On the main mounting frame 211, each wing support body 104 is provided with a fixed seat 213 at its axial position. Each fixed seat 213 is equipped with a connecting nut 215. At the end of the connecting arm 221 near the main mounting frame 211, a fixing nut 222 is provided. During installation, a long screw 223 is used to pass through the connecting nut 215 on the fixed seat 213 and the fixing nut 222 on the connecting arm 221 in sequence, and is tightened by thread. The long screw 223 performs well in bearing tensile and shear forces, and can ensure that there will be no unexpected separation or displacement between the connecting arm 221 and the main mounting frame 211.

[0032] The bottom of the right-angle connecting bracket 232 is provided with at least two third studs 231. The connecting arm 221 is fixed to the third studs 231 by the threaded connection of the connecting bolt 224. The connecting bolt 224 is also threaded with a locking nut 225 at the point where it passes through the connecting arm 221.

[0033] At the bottom of the right-angle connecting bracket 232, at least two third studs 231 are provided. During installation, the mounting holes at the ends of the connecting arm 221 are aligned with these third studs 231. Then, the connecting bolts 224 are passed through the mounting holes from below or the side and threadedly connected to the third studs 231. To provide additional anti-loosening protection, a locking nut 225 is threadedly fitted at the part where the connecting bolts 224 pass through the connecting arm 221. The connecting bolts 224 are responsible for providing the main tightening force, pulling the connecting arm 221 tight onto the right-angle connecting bracket 232. After tightening, the locking nut 225 fits against the surface of the connecting arm 221, effectively preventing the connecting bolts 224 from loosening under continuous vibration.

[0034] The top of the main support 101 is provided with a power module 102 for power storage and supply. The inside of the main support 101 is provided with a control module 103 for integrated control of electrical equipment. The bottom of the main mounting bracket 211 is provided with a number of connecting motherboards 214 equal to the number of servo mounting brackets 216. The connecting motherboards 214 are used for electrical connection with the servo body 218.

[0035] At the top of the main support frame 101 of the UAV, a power module 102 is installed. Its principle is to store and provide power for all electronic devices of the UAV, including the servo motors. Inside the main support frame 101, a control module 103 is integrated. Its principle is to receive remote control signals or instructions from the autonomous navigation program and to integrate control and signal processing of all electrical devices. At the bottom of the main mounting bracket 211 of the servo motor mounting mechanism, there are connection motherboards 214 in number equal to the number of servo motor mounting brackets 216. The principle of the connection motherboards 214 is to act as a centralized electrical interface adapter board. They are connected to the control module 103 and the power module 102 of the main body through cables. When the servo motor body 218 is fixed on the servo motor mounting bracket 216, its power line and signal line can be connected to the corresponding interface of the connection motherboard 214 nearby to complete the electrical connection.

[0036] Working principle: The UAV body 100 consists of a main support 101 and four openable wing support bodies 104. The top of the wing support body 104 is equipped with a wing body 105. The servo mounting bracket 200 serves as a passive load-bearing platform and consists of a central mounting frame 210, four connecting arms 220, and four wing connecting brackets 230. The center mounting bracket 210 consists of a main mounting bracket 211 directly connected to the bottom of the main body bracket 101 and a fixing bracket 219 fixed thereto by a first stud 212. The bottom of the fixing bracket 219 is provided with a servo mounting bracket 216 for accommodating the servo body 218. During installation, the servo body 218 is first slid into the servo mounting bracket 216, and then connected to the threaded grooves in the second studs 217 evenly distributed on both sides of the servo mounting bracket 216 by bolts, thereby being firmly fixed. Meanwhile, the wing connecting bracket 230 is fitted onto the wing bracket body 104 by means of a sleeve. Each wing connecting bracket 230 consists of a right-angle connecting frame 232, a side connecting plate 233 connected by bolts, and a top connecting plate 234 spanning the top, forming a clampable rigid frame. In order to adapt to brackets of different sizes, the top connecting plate 234 has an adjustment slot 235, which can be locked after initial positioning by cooperating with the connecting bolt 224 to achieve fixation. Each connecting arm 220 consists of a connecting support arm 221. One end of the connecting support arm 221 passes through the connecting nut 215 in the fixing seat 213 on the main mounting frame 211 and the fixing nut 222 at its own end via a long screw 223, and is firmly connected to the central mounting frame 210. The other end is connected to the third stud 231 at the bottom of the right-angle connecting frame 232 via a connecting bolt 224, and a locking nut 225 is fitted on the connecting bolt 224 to prevent loosening. This firmly fixes the connecting support arm 221 to the wing connecting bracket 230, and distributes the weight and workload of the servo motor body 218 to the four sturdy wing connecting brackets 230 through the central mounting frame 210 and the connecting support arm 221, thus ensuring the overall stability. Furthermore, the power module 102 at the top of the main support 101 is responsible for energy storage and power supply, and the internal control module 103 is responsible for processing control commands. The electrical connection is achieved through the connection motherboard 214 located at the bottom of the main mounting bracket 211. The connection motherboard 214 serves as a centralized interface, connecting the power module 102 and the control module 103 via cables, and providing power and signal interfaces for each servo body 218 mounted on the servo mounting bracket 216, thereby completing the entire workflow from mechanical installation to electrical connection.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
