Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicles (UAVs), specifically to a UAV frame structure and a UAV. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own program control devices. They are high-tech products integrating aerodynamics, materials mechanics, automatic control technology, and software technology. With the rapid advancement of science and technology, UAVs, as high-tech intelligent products, are no longer limited to early military equipment. Today, they are widely used in many fields such as emergency rescue, aerial film and television shooting, land surveying, power and pipeline inspection, pesticide spraying, and entertainment. They are also constantly becoming smaller, more accessible, and more user-friendly, and in recent years, UAVs have shown an explosive growth trend.

[0003] Most drone frames are currently integrated structures. Some long-endurance drones have batteries installed inside the wings, with multiple small batteries evenly distributed around the fuselage through radial battery fixing frames, which balances the center of gravity and enhances structural strength.

[0004] However, the aforementioned battery installation method, where distributed batteries require independent electrical connections and thermal management systems, results in a 30% increase in the number of parts, a higher failure rate, and the wings are prone to deformation upon collision, potentially squeezing the batteries. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a drone frame structure and a drone, aiming to solve the problem that the current distribution method of drone batteries easily leads to a high failure rate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drone frame structure, the drone frame structure comprising a shelf assembly and side plate assemblies symmetrically disposed on both sides of the shelf assembly; The shelf assembly includes an upper shelf and a lower shelf arranged in parallel, wherein the upper shelf, the lower shelf, and the side panel assembly enclose a placement space for accommodating a battery; The upper plate, the lower plate, and the side plate assembly are provided with a power distribution plate at one end. The lower plate is provided with a battery fixing clip at the end away from the power distribution plate. The battery is fixed in the placement space by the power distribution plate and the battery fixing clip. The upper plate, the lower plate, and the side plate assembly are all hollowed out.

[0007] According to one aspect of the above technical solution, the side panel assembly includes a side panel body and at least two mounting edges arranged parallel to the side panel body, the mounting edges being arranged along the length direction of the side panel body.

[0008] According to one aspect of the above technical solution, the side plate body is provided with a plurality of first recesses, the first recesses are disposed between the mounting edges, and the first recesses and the mounting edges form a first mounting part for connecting the machine arm.

[0009] According to one aspect of the above technical solution, reinforcing ribs are provided on the mounting edges on both the upper and lower sides of any of the first mounting parts, and one end of the arm is fixedly connected between the reinforcing ribs.

[0010] According to one aspect of the above technical solution, the side plate body is further provided with a second recess, which is located directly below the mounting edge and is connected to the landing support of the UAV.

[0011] According to one aspect of the above technical solution, a power distribution board cover is also provided on the side of the power distribution board away from the power distribution board. The power distribution board cover covers the power distribution board and is fixedly connected to one end of the side plate body.

[0012] In another aspect, this utility model proposes an unmanned aerial vehicle (UAV) comprising the UAV frame structure described above.

[0013] In summary, the UAV frame structure proposed in this utility model, by setting up an upper plate, a lower plate, and side plate assemblies, encloses a space for accommodating the battery. Simultaneously, the battery is secured within this space using a power distribution board and battery fixing clips, preventing wing compression that could lead to battery deformation and reducing the failure rate. Furthermore, since the upper plate, lower plate, and side plate assemblies are all hollowed out, there is no need for an independent electrical connection and thermal management system for the distributed batteries, reducing the number of components and providing better heat dissipation performance.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the related listed items.

[0020] Please see Figures 1-4 The diagram shown is a schematic representation of a drone frame structure according to an embodiment of the present invention. The drone frame structure includes a shelf assembly and side plate assemblies 300 symmetrically disposed on both sides of the shelf assembly, wherein: To construct a placement space for the battery 1000, the shelf assembly includes an upper shelf 100 and a lower shelf 200 arranged in parallel. The upper shelf 100 and lower shelf 200 are securely fastened to the side panel assembly 300 with screws to form a stable frame structure for placing the battery 1000. Furthermore, a power distribution plate 600 is provided at one end of the upper shelf 100, lower shelf 200, and side panel assembly 300, and a battery fixing clip 500 is provided at the end of the lower shelf 200 away from the power distribution plate 600. The battery 1000 is fixed in the placement space by the power distribution plate 600 and the battery fixing clip 500. Moreover, the upper shelf 100, lower shelf 200, and side panel assembly 300 are all hollowed out to facilitate heat dissipation for the battery 1000 placed within them.

[0021] The side panel assembly 300 includes a side panel body 310 and at least two mounting edges 320 parallel to the side panel body 310, with the mounting edges 320 arranged along the length direction of the side panel body 310. In this embodiment, the landing gear 900 and the arm 800 of the UAV are both mounted on the side panel body 310.

[0022] The side plate body 310 is provided with a plurality of first recesses 311, which are located between two mounting edges 320. The first recesses 311 and the mounting edges 320 form a first mounting portion for connecting the arm 800. The first mounting portion is contoured to the mounting end of the arm 800, so that when the mounting end of the arm 800 is embedded in the first mounting portion, it can be fixedly connected to the side plate body 310 by using fasteners to connect the mounting edges 320 at the upper and lower ends.

[0023] Furthermore, the mounting edge 320 is provided with reinforcing ribs 321 at the upper and lower ends of the first mounting part. When the mounting end of the arm 800 is connected to the mounting edge 320 at the upper and lower ends by fasteners, the reinforcing ribs 321 provide stress strength for the connection, so as to avoid deformation of the arm 800 and the mounting edge 320 during the installation process, which would lead to the arm 800 failing to be installed correctly and affecting the stability of the UAV.

[0024] Furthermore, a second recess 312 is provided on the side plate body 310. The second recess 312 is located directly below the mounting edge 320 and is used to connect the landing gear of the UAV.

[0025] The power distribution board 600 is fixedly connected to one end of the side panel body 310. A power distribution board cover 700 is also provided on one side of the power distribution board 600. The power distribution board cover 700 covers the power distribution board 600 and is fixedly connected to one end of the side panel body 310.

[0026] It should be noted that the drone frame uses 6061T6 aluminum alloy as its main material for its frame structure. The upper plate 100, two side plates 310, and the lower plate 200 are connected by screws to create a stable and highly integrated main frame. Specific slots and fixing holes on each component allow for precise installation and fixation of components such as the power distribution board 600, arms 800, landing gear 900, GPS, shell, flight control system, and pod bracket. The central section provides space and rails for the battery 1000, ensuring convenient and stable installation. The coordinated operation of all parts gives the frame a simple, compact design (690mm wheelbase) while maintaining high rigidity, thus supporting the drone's ability to achieve high payload (1KG) and long flight time (1 hour).

[0027] In summary, the UAV frame structure proposed in this utility model, by setting up an upper plate, a lower plate, and side plate assemblies, encloses a space for accommodating the battery. Simultaneously, the battery is secured within this space using a power distribution board and battery fixing clips, preventing wing compression that could lead to battery deformation and reducing the failure rate. Furthermore, since the upper plate, lower plate, and side plate assemblies are all hollowed out, there is no need for an independent electrical connection and thermal management system for the distributed batteries, reducing the number of components and providing better heat dissipation performance.
