Description

Technical Field

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

[0002] In the application and development of drone technology, the drone frame, as a key component that carries the drone's power system and various equipment, directly affects the drone's portability, stability, and user experience. Currently, most drone frames on the market adopt a fixed structure design. Although this structure can ensure the stability of the drone during flight to a certain extent, it has obvious drawbacks. Because the frame cannot be folded and stored, the overall size of the drone is large, making it extremely inconvenient to carry and transport. This is especially true for scenarios requiring outdoor operations, aerial photography and mapping, or emergency rescue, where operators find it difficult to carry the drone easily, limiting its application in more scenarios. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a foldable drone frame, which solves the problem that the drone's overall size is too large and extremely inconvenient to carry and transport because the frame cannot be folded and stored.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a foldable drone frame, comprising: a frame, and a folding assembly, wherein the outer wall of the folding assembly is fixedly connected to the outer wall of the frame, and the inner wall of the folding assembly is threadedly connected to an installation assembly; the folding assembly includes extension blocks, two sets of which are provided, and the outer wall of each set of extension blocks is fixedly connected to the outer wall of the frame; the outer wall of the frame is rotatably connected to a frame body via a threaded cylinder, the outer wall of the threaded cylinder is fixedly connected to the outer wall of the frame, the outer wall of the frame body is secured to a fixing post via a slot, and the slot is located within the wall of the frame body; a brushless motor is fixedly installed on the outer wall of the frame body; the outer wall of the threaded cylinder is rotatably connected to the inner wall of the frame body; and the extension blocks have the same structure as the threaded cylinder.

[0005] Preferably, the mounting assembly includes a baffle, the inner wall of the top of the baffle is rotatably connected with balls, and the balls are arranged in a circular array along the central axis of the baffle. A threaded column is fixedly connected to the top of the baffle, and a threaded groove corresponding to the threaded cylinder is formed in the wall of the threaded column. A support foot is fixedly connected to the bottom of the baffle.

[0006] Preferably, the outer wall of the threaded column is threadedly connected to the inner wall of the threaded cylinder, and the outer wall of the ball is rolledly connected to the outer wall of the frame.

[0007] This invention provides a foldable and retractable drone frame. It offers the following advantages:

[0008] (i) This foldable drone frame achieves the folding and unfolding function through the linkage design of the frame and folding components. The frame can rotate and fold around the threaded cylinder on the outer wall of the frame. When folded, it fits the outer wall of the frame, compressing the overall volume to the compact state of a traditional frame, making it convenient to carry by hand or store in a backpack. When unfolded, it forms a rigid connection through the snap-fit ​​of the slot and the fixed column, ensuring that the frame will not shake during flight, thus solving the problem of insufficient stability of portable devices.

[0009] (II) This foldable drone frame features a ball bearing array structure on the top of the baffle in the mounting components. When the frame rotates, the balls generate rolling friction with the outer wall of the frame, significantly reducing the resistance to folding and unfolding operations. Even with one hand, the folding and unfolding actions can be easily completed. The bottom support feet are made of non-slip material, which increases the friction with the ground when landing. This ensures the frame remains stable on complex terrains such as grass and gravel, preventing the drone from tipping over during takeoff and landing. The threaded connection design of the threaded column and threaded cylinder ensures a firm connection between the mounting components and the folding components, while also providing convenience for later maintenance. After a crash, simply rotate the baffle and raise or lower the threaded column to release the restriction on the frame, allowing for quick disassembly and replacement of damaged frame components without the need for professional tools or complex operations. This significantly shortens maintenance time and reduces costs. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a foldable drone frame, comprising: a frame 1, and a folding component 2. The outer wall of the folding component 2 is fixedly connected to the outer wall of the frame 1, and the inner wall of the folding component 2 is threadedly connected to an installation component 3. The folding component 2 includes extension blocks 26, two sets of which are provided, and the outer wall of each set of extension blocks 26 is fixedly connected to the outer wall of the frame 1. The outer wall of the frame 1 is rotatably connected to a frame body 22 via a threaded cylinder 21, the outer wall of the threaded cylinder 21 being fixedly connected to the outer wall of the frame 1, and the outer wall of the frame body 22 being connected via a slot. The frame 22 is secured with a fixed post 24, and the slot 25 is located in the wall of the frame 22. A brushless motor 23 is fixedly installed on the outer wall of the frame 22. The outer wall of the threaded cylinder 21 is rotatably connected to the inner wall of the frame 22. The operator holds the frame 22 and overcomes the rotational resistance between it and the threaded cylinder 21 to rotate the frame 22 from the folded state around the threaded cylinder 21 to the working position. At this time, the slot 25 on the frame 22 is engaged with the fixed post 24. The fixed post 24 plays a limiting and fixing role, ensuring the stability of the frame 22 in the unfolded state and preventing shaking during operation.

[0017] The mounting assembly 3 includes a baffle 31. The inner wall of the top of the baffle 31 is rolled with balls 32, which are arranged in a circular array along the central axis of the baffle 31. The top of the baffle 31 is fixedly connected with a threaded post 33, and the bottom of the baffle 31 is fixedly connected with a support foot 34. When the frame 22 needs to be replaced after the drone crashes, simply rotate the baffle 31 to rotate the threaded post 33 and release the restriction on the frame 22. Then the frame 22 can be removed from the threaded cylinder 21, which facilitates the replacement of the frame 22. The outer wall of the threaded post 33 is threadedly connected to the inner wall of the threaded cylinder 21, and the outer wall of the balls 32 is rolledly connected to the outer wall of the frame 22.

[0018] The core of this foldable drone frame lies in the structural cooperation between the folding component 2 and the mounting component 3, which enables the frame to be flexibly unfolded and stably supported. The frame 1 serves as the basic structure, and the folding component 2, which is fixedly connected to its outer wall, is the key part to realize the folding function. Its top is fixedly connected to the drone body. The two sets of extension blocks 26 in the folding component 2 are fixed to the outer wall of the frame 1, providing a folding position for the rotation of the two sets of frame bodies 22. The threaded cylinder 21 is fixed to the outer wall of the frame 1, and the frame body 22 achieves the rotation movement around the frame 1 through the rotational connection with the threaded cylinder 21. This design allows the frame body 22 to be unfolded when in use and folded to fit the frame 1 when stored, thereby reducing the overall volume.

[0019] When the frame needs to be unfolded, the operator holds the frame 22, overcomes the rotational resistance between it and the threaded cylinder 21, and rotates the frame 22 from the folded state around the threaded cylinder 21 to unfold it to the working position. At this time, the slot 25 on the frame 22 engages with the fixing post 24. The fixing post 24 plays a limiting and fixing role, ensuring the stability of the frame 22 in the unfolded state and avoiding shaking during operation. The brushless motor 23 installed on the outer wall of the frame 22 provides power for the flight of the UAV.

[0020] Mounting assembly 3 serves as a connector and support within the frame. The inner wall of the top of baffle 31 is connected to a rolling ball bearing 32, which is arranged in a circular array along the central axis of baffle 31. When the frame 22 rotates, the ball bearing 32 rolls into contact with the outer wall of the frame 22. This rolling connection method greatly reduces the friction when the frame 22 rotates, making the folding and unfolding operations smoother. The support foot 34 at the bottom of baffle 31 supports the ground after the frame is unfolded, enhancing the stability of the frame. The threaded post 33 is threadedly connected to the inner wall of the threaded cylinder 21. This design firmly connects mounting assembly 3 and folding assembly 2 together, ensuring the reliability of the entire frame structure.

[0021] During the storage process, first release the engagement between the slot 25 and the fixed post 24, then rotate the frame 22 in the opposite direction. The frame 22 at the extension block 26 is rotated and folded around the threaded cylinder 21 until it is close to the outer wall of the frame 1, thereby achieving compact storage of the frame, which is convenient for carrying and storage. During the entire operation, the components cooperate with each other, which not only ensures the structural stability of the drone during flight, but also realizes the foldable storage function of the frame, meeting the needs of portability and practicality in actual use. Moreover, when the frame 22 needs to be replaced after the drone crashes, simply rotate the baffle 31, which drives the threaded post 33 to rotate and release the restriction on the frame 22. Then the frame 22 can be taken out from the threaded cylinder 21, which makes it easy to replace the frame 22.
