Description

Technical Field

[0001] The utility model relates to the technical field of racing drones, and specifically, it is a folding and quick-release fuselage of a racing drone. Background Art

[0002] The racing drone, also known as the "FPV quadcopter drone", is a model aircraft extreme sport that has emerged globally this year. Although the racing drone belongs to the quadcopter drone, it is different from general consumer drones. Its speed can reach over 200 kilometers per hour, and it can also complete various complex aerial stunts, such as rolls, broken S, and figure eights and other high-difficulty actions.

[0003] After investigation, it is found that the existing arms of racing drones are generally fixed-size arms, such as 5 inches or 7 inches, etc., with non-replaceable power, and they are not convenient for storage and carrying. Secondly, there are many parts of the racing drone. The existing structural design is usually the linear stacking of parts, which is complex to disassemble and assemble, and difficult to disassemble and repair. In emergency scenarios such as the need for the whole machine to be quickly deployed and withdrawn, and convenient repair and replacement of parts, the shortcomings are obvious, and it is difficult to give full play to the significant advantages of the racing drone being flexible, maneuverable, light and convenient. Therefore, improvements need to be made in the fuselage structure design. Summary of the Invention

[0004] The purpose of the utility model is to provide a folding and quick-release fuselage of a racing drone.

[0005] The technical solution to achieve the purpose of the utility model is: a folding and quick-release fuselage of a racing drone, including a camera, a central fixing plate, a cabin, and an arm folding mechanism; the camera and the cabin are fixed on the central fixing plate, and the arm folding mechanism is fixed at the bottom of the central fixing plate.

[0006] Further, the camera and the cabin are fixed on the central fixing plate through the limit mechanism fixing screw holes at the front end of the central fixing plate.

[0007] Further, the arm folding mechanism includes N gear arms and an arm limit mechanism. There is an arm fixing screw hole at the center position of the arm limit mechanism. Above the front end of the gear arm is a motor mounting hole position for installing the motor base. The ends of the gear arms are evenly distributed on the arm limit mechanism around the arm fixing screw hole through gear meshing; the arm folding mechanism is fixed below the central fixing plate through the screws of the arm fixing screw hole.

[0008] Further, a camera fixing screw hole is provided on one side of the bottom of the camera, a cabin fixing screw hole is provided on one side of the bottom of the cabin, the limit mechanism fixing screw hole is communicated with the camera fixing screw hole and the cabin fixing screw hole, and the cabin fixing screw hole and the camera fixing screw hole overlap on the limit mechanism fixing screw hole from top to bottom in sequence and are fixed on the central fixing plate through screws.

[0009] Furthermore, the camera is installed on the central fixing plate under the restriction of the camera limiting mechanism. At the same time, the camera fixing screw holes coincide with the limiting mechanism fixing screw holes, and the camera fixing screw holes are located above the limiting mechanism fixing screw holes.

[0010] Furthermore, the nacelle is installed on the central fixing plate under the restriction of the nacelle limiting mechanism. At the same time, the nacelle fixing screw holes coincide with the limiting mechanism fixing screw holes, and the nacelle fixing screw holes are located at the top. From top to bottom, they are the nacelle fixing screw holes, the camera fixing screw holes, and the limiting mechanism fixing screw holes in sequence.

[0011] Compared with the prior art, the remarkable advantages of the present utility model are as follows: (1) The power mode can be quickly changed by removing one central fixing nut of the central fixing plate, and the machine arms can be quickly folded and stored for easy carrying and transportation. (2) The quick replacement of the camera or nacelle and other drone modules can be achieved by removing one front fixing nut of the central fixing plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present utility model will be further described below in conjunction with the accompanying drawings of the specification and embodiments.

[0020] As Figure 1 shown, it is a schematic diagram of the whole machine of the foldable and quick-release airframe of the drone assembled.

[0021] As Figure 2As shown, the modular design of the foldable quick-detachable body of the flying drone includes a camera 4, a central fixing plate 6, a cabin 7, and an arm folding mechanism 5 (including a geared machine arm 1, a machine arm fixing screw hole 2, and a machine arm limiting mechanism 3). The camera 4 and the cabin 7 are fixed to the central fixing plate 6 by screws of the fixing screw hole 9 of the limiting mechanism at the front end of the central fixing plate 6. By removing the screws of the fixing screw hole 9 of the limiting mechanism, the camera 4 and the cabin 7 can be easily and quickly disassembled, reducing the assembly time.

[0022] like Figure 3 As shown, four gear arms 1 are meshed at the ends through gears and are evenly distributed on the motor base 14 around the arm fixing screw holes 2. The ends of the gear arms 1 can mesh with gears to achieve the rapid folding of four arms by folding any two arms. The front end of the gear arm 1 is the motor installation hole. Figure 3 The arm folding mechanism 5 shown is fixed below the central fixing plate 6 by screws in the arm fixing screw holes 2 .

[0023] like Figure 4 As shown, rotating any arm can drive the other arms to move together through the gear at the end of the gear arm 1. The arm limit mechanism 3 limits the arm deployment angle. The power mode can be quickly changed by removing a screw located in the arm fixing screw hole 2. In other words, the arm folding mechanism can be separated from the center fixing plate by removing a center fixing nut located in the center fixing plate. The power mode can be quickly changed by changing the size of the arm folding mechanism; and the arm can be quickly folded and stored for easy carrying and transportation.

[0024] like Figure 5 As shown, 9 is a fixing screw hole for the limiting mechanism, 10 is a fixing screw hole for the camera, and 11 is a fixing screw hole for the cabin. The fixing screw hole 9 for the limiting mechanism is connected with the fixing screw hole 10 for the camera and the fixing screw hole 11 for the cabin, and one screw can be used to fix them to the center fixing plate 6 at the same time.

[0025] like Figure 6 , 12 is a camera limiting mechanism, 13 is a cabin limiting mechanism, and the two limiting mechanisms are used to limit the positions of the camera 4 and the cabin 7.

[0026] like Figure 7 As shown, the camera 4 is installed on the central fixing plate 6 under the restriction of the camera limiting mechanism 12, and the cabin 7 is installed on the central fixing plate 6 under the restriction of the cabin limiting mechanism 13. The camera fixing screw hole 10 of the camera 4 and the cabin fixing screw hole 11 of the cabin 7 overlap on the limiting mechanism fixing screw hole 9, and are fixed to the central fixing plate by a screw. That is, by removing a screw located in the limiting mechanism fixing screw hole of the central fixing plate, the central fixing plate can be separated from the camera and the cabin, and quick replacement and maintenance can be completed.

[0027] In the actual use process of the solution of the present utility model, the arm folding mechanism 5 can be separately replaced with different power sizes and connected to the central fixing plate 6 through the arm fixing screw holes 2 to meet the requirements of different scenarios. Wear and tear are inevitable during flight. When the racing drone is damaged, the whole aircraft can be disassembled by a screw of the arm fixing screw hole 2 and a screw of the fixing screw hole 9 of the front-end limiting mechanism of the central fixing plate 6, and the camera 4, the cabin 7, the arm folding mechanism 5, etc. can be quickly replaced.

[0028] Preliminary measurement shows that after applying the structural design of the present utility model, the replacement time of the racing drone module can be completed within 300 seconds, saving 50% of the time compared with the general structural design. At the same time, on the premise of ensuring the structural strength and use toughness of the airframe, the overall structural size of the racing drone is greatly streamlined, so as to give full play to the unique advantages of the racing drone being smart, flexible and light.
