Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV frame structure. Background Technology

[0002] A drone is an aircraft that can fly remotely or autonomously without the need for personnel. In recent years, it has been widely used in military, civilian and commercial fields. The drone's frame is the basic structure that supports all equipment and determines the drone's performance and applicable scenarios.

[0003] The existing utility model patent with publication number CN215475755U discloses a drone frame that "has multiple partitions in the middle, providing a large space to accommodate large or numerous devices and sensors. The partition assembly includes an upper partition, a main partition, and a lower partition. The upper partition is located above the main partition, and the lower partition is located below the main partition, having three layers of partitions, providing a large space for large or numerous devices and sensors." While this addresses the issue that "common frame types only have two layers of partitions, which only meet the minimum configuration requirements," it does not provide sufficient space for large or numerous devices and sensors. In situations requiring secondary development of additional equipment or autonomous flight, space is often insufficient, leading to a lack of space to accommodate the added equipment. However, when installing motors on the frame, if pre-positioning is not performed, the motor may shift during installation, making subsequent fixation difficult. Currently, pre-positioning is mostly achieved using mechanical positioning, bosses, or temporary fixing clamps. Mechanical positioning and bosses are inflexible and cannot adapt to different motor models, while temporary fixing clamps are complex to operate and cannot be quickly switched according to specific motor models, resulting in poor versatility. Therefore, a new frame structure for unmanned aerial vehicles (UAVs) is proposed. Utility Model Content

[0004] Therefore, it is necessary to provide a frame structure for a drone to address the aforementioned technical problems.

[0005] To solve the above-mentioned technical problems, this utility model solves the problem of being unable to adapt to different models of motors and having poor versatility through the following technical solution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A frame structure for a drone, comprising:

[0008] A drone frame, wherein connecting arms are fixedly connected to all four side walls of the drone frame, and a motor mounting plate is provided on one side of each connecting arm, and motor mounting holes are provided on the surface of the motor mounting plate;

[0009] The built-in groove is formed on the inner wall of the motor mounting hole. The inner cavity of the built-in groove is provided with two auxiliary mounting pieces. A limiting groove is formed on one side of the bottom end of the auxiliary mounting pieces. A moving groove is formed on one side of the top end of the connecting arm. A fixing plate is provided between the inner wall of the moving groove and the motor mounting plate.

[0010] As a preferred embodiment of the frame structure of the UAV provided by this utility model, one side of the surfaces of the two auxiliary mounting plates is threaded with a bidirectional threaded rod, and one end of the bidirectional threaded rod is rotatably connected to the inner wall of the built-in groove.

[0011] In a preferred embodiment of the frame structure of the UAV provided by this utility model, one end of the bidirectional threaded rod rotates through the inner wall of the built-in groove to the outside of the motor mounting plate and is fixedly connected to a knob.

[0012] In a preferred embodiment of the frame structure of the UAV provided by this utility model, a limiting plate is fixedly connected to one side of the inner wall of the built-in groove, and the auxiliary mounting piece is slidably connected to the limiting plate through the limiting groove.

[0013] As a preferred embodiment of the frame structure of the UAV provided by this utility model, one side wall of the connecting arm has a notch, and both sides of the inner wall of the moving groove are provided with vertical holes.

[0014] In a preferred embodiment of the frame structure of the unmanned aerial vehicle provided by this utility model, a movable block is provided in the inner cavity of the movable slot, one end of the fixed plate is fixedly connected to the movable block, and the other end of the fixed plate is detachably fixedly connected to the motor mounting plate.

[0015] In a preferred embodiment of the frame structure of the unmanned aerial vehicle provided by this utility model, side blocks are fixedly connected to both sides of the movable block, and the two side blocks are slidably connected to the inner cavities of the two vertical holes respectively.

[0016] In a preferred embodiment of the frame structure of the UAV provided by this utility model, a screw is threadedly connected to the surface of one of the side blocks.

[0017] In a preferred embodiment of the frame structure of the UAV provided by this utility model, one end of the screw is rotatably connected to the inner wall of the vertical hole on the same side, and the other end of the screw rotatably penetrates the inner wall of the vertical hole on the same side to the notch.

[0018] In a preferred embodiment of the frame structure of the unmanned aerial vehicle provided by this utility model, an adjustment knob is fixedly connected to the other end of the screw.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model provides a frame structure for a drone. By setting two auxiliary mounting plates, when the operator installs different models of motors on the motor mounting plate through the motor mounting holes, the two auxiliary mounting plates can move relative to each other or away from each other under the limiting action of the limiting groove and the limiting plate, so as to flexibly adjust the spacing between the auxiliary mounting plates, adapt to motor bases or motors of different sizes, and are simple to operate and highly versatile.

[0021] This utility model provides a frame structure for a drone, which, by setting a fixed plate, a movable block, and a side block, allows the screw to be rotated as needed. Under the guidance and limiting action of the side block, the movable block moves the motor mounting plate to one side through the fixed plate, thereby increasing the wing length. By adjusting the wing length, the aerodynamic performance of the drone can be optimized, making it suitable for diverse missions such as long-endurance reconnaissance and high-payload transportation.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A frame structure for a drone includes a drone frame 1, with connecting arms 2 fixedly connected to the four side walls of the drone frame 1. A motor mounting plate 3 is provided on one side of the connecting arm 2, and motor mounting holes 4 are provided on the surface of the motor mounting plate 3 for mounting a drive motor.

[0033] The built-in groove 5 is opened on the inner wall of the motor mounting hole 4. The inner cavity of the built-in groove 5 is provided with two auxiliary mounting pieces 6. The two auxiliary mounting pieces 6 are symmetrically distributed and their opposite surfaces are arc-shaped. A limiting groove 7 is opened on one side of the bottom end of the auxiliary mounting piece 6. A moving groove 8 is opened on one side of the top end of the connecting arm 2. A fixing plate 9 is provided between the inner wall of the moving groove 8 and the motor mounting plate 3.

[0034] Preferably, one side of the surface of the two auxiliary mounting pieces 6 is threaded with a bidirectional threaded rod 10. The two auxiliary mounting pieces 6 are distributed on two opposite threads of the bidirectional threaded rod 10. One end of the bidirectional threaded rod 10 is rotatably connected to the inner wall of the built-in groove 5. One end of the bidirectional threaded rod 10 rotatably passes through the inner wall of the built-in groove 5 to the outside of the motor mounting plate 3 and is fixedly connected with a knob 11. One side of the inner wall of the built-in groove 5 is fixedly connected with a limiting plate 12, which cooperates with the limiting groove 7 to guide and limit the auxiliary mounting pieces 6. The auxiliary mounting pieces 6 are slidably connected to the limiting plate 12 through the limiting groove 7.

[0035] Preferably, one side wall of the connecting arm 2 has a notch 13 to provide installation space for the adjusting knob 18, and also facilitates subsequent rotation of the adjusting knob 18 by the operator. Vertical holes 14 are provided on both sides of the inner wall of the moving groove 8. A moving block 15 is provided in the inner cavity of the moving groove 8. One end of the fixing plate 9 is fixedly connected to the moving block 15, and the other end of the fixing plate 9 is detachably fixedly connected to the motor mounting plate 3, facilitating subsequent disassembly and replacement of parts of the motor mounting plate 3. Side blocks 16 are fixedly connected to both sides of the moving block 15. Each side block 16 is slidably connected to the inner cavity of the two vertical holes 14. The side block 16 and the vertical holes 14 play a guiding and limiting role for the moving block 15. One of the side blocks 16 is threadedly connected to a screw 17. The screw 17 is used to move the motor mounting plate 3 to one side, moving it away from or closer to the connecting arm 2. One end of the screw 17 is rotatably connected to the inner wall of the vertical hole 14 on the same side. The other end of the screw 17 rotates through the inner wall of the vertical hole 14 on the same side to the notch 13. The other end of the screw 17 is fixedly connected to an adjustment knob 18.

[0036] The usage process of the drone frame structure provided by this utility model is as follows: First, when the operator installs the motor or motor mount at the motor mounting hole 4, they rotate the knob 11 by hand, causing the bidirectional threaded rod 10 to rotate, so that the two auxiliary mounting pieces 6 move in opposite directions, allowing the gap between them to accommodate the motor or motor mount. After placing the motor or motor mount between the two auxiliary mounting pieces 6, the operator can rotate the knob 11 in the opposite direction, so that the two auxiliary mounting pieces 6 move relative to each other under the limiting action of the limiting plate 12 and the limiting groove 7, thus achieving the initial positioning of the motor or motor mount. When it is necessary to adjust the length of the wing part, the operator can rotate the adjusting knob 18 by hand, causing the screw 17 to rotate, so that the moving block 15, under the limiting action of the side block 16 and the vertical hole 14, drives the motor mounting plate 3 to move to one side through the fixing plate 9, thereby realizing the adjustment of the length of the wing part of the drone frame 1.
