Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with quick disassembly, assembly and folding functions. Background Art

[0002] An unmanned aerial vehicle, abbreviated as "UAV" and with the English abbreviation "UAV", is an unpiloted aircraft controlled by a radio remote control device and a self-provided program control device. From a technical perspective, it can be classified into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned parasol-wing aircraft, etc. UAVs can carry a variety of loads to complete various complex tasks and are specifically widely used in many fields such as photography, pesticide spraying, fire prevention and disaster relief, communication, drug suppression, etc.

[0003] The existing UAVs have a relatively single structure, and the arms and the fuselage are both fixed structures. During the flight of the UAV, it is very easy to be affected by the external environment and lose stability. Some UAVs performing camera tasks need to install cameras. Due to the inability to maintain a relatively stable flight, it is very easy to capture the arms, which greatly affects the shooting effect, greatly prolongs the operation time of the UAV, and increases the task cost of the UAV. At the same time, due to the integral molding of the fuselage and the arms, the volume of the UAV is very large. Each time it is used, a large transportation tool is required for transportation, or the UAV is disassembled. When in use, the parts of the UAV are transported to a designated location and then assembled. After the assembly is completed, debugging is also required before normal use, which is very inconvenient. This greatly restricts the use of UAVs and the cost is very high, affecting the development of UAVs. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that the current UAV has a fixed and single structure, the arms are easy to affect the shooting effect, and the loading and unloading is difficult, and the later maintenance is difficult.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an unmanned aerial vehicle with quick disassembly, assembly and folding functions, including an unmanned aerial vehicle frame and an unmanned aerial vehicle body. The unmanned aerial vehicle frame and the unmanned aerial vehicle body are fixedly connected through an arm connecting piece. A buckle fixed end is fixedly installed on the arm connecting piece through screws. Buckle movable ends are fixedly assembled on both sides of the unmanned aerial vehicle body. A folding leg side plate is fixed on the lower surface of the end of the unmanned aerial vehicle frame. A leg is movably installed inside the folding leg side plate. A leg fixing spring pin for convenient limit is arranged at the connection end of the leg and the folding leg side plate.

[0006] The unmanned aerial vehicle frame is composed of two first square carbon tubes made of high-density carbon fiber fixed on the unmanned aerial vehicle body and two second square carbon tubes made of high-density carbon fiber with motors and rotors fixed at both ends.

[0007] Two semi-circular grooves that cooperate with the tripod fixing spring pins are provided on the folding jib side plate.

[0008] The first square carbon tubes on both sides of the UAV fuselage are horizontally embedded and fixedly installed, and the installation angle between the first square carbon tube and the second square carbon tube is 90°.

[0009] A plurality of mounting holes are provided on the second square carbon tube at the arm connecting member mounting section.

[0010] Internal thread expansion holes are provided at the bottom of the tripod.

[0011] The beneficial effects of the present utility model are as follows:

[0012] (1) The UAV of the present utility model adopts an "I"-shaped frame design, and the arms are parallel to both sides of the frame, which is more stable compared with the traditional structure;

[0013] (2) The UAV frame and the UAV fuselage are assembled to form the aircraft body. The fuselage is responsible for placing the integrated circuit element modules, batteries and mounts, while the frame part consists of arms and a tripod. Through the tightening buckle, the UAV fuselage and the frame part can be quickly installed and removed, and the removed frame part can also complete the efficient folding of the tripod. No complex tools or long-time operations are required, improving the disassembly and assembly efficiency. The quick-release structure realizes the stable connection between the arms and the tripod in a limited space, while ensuring the compactness of the structure, reducing the overall volume and weight of the UAV, which is beneficial to the portability and transportation convenience of the UAV;

[0014] (3) Adopting a quick-release structure design reduces the loading and unloading difficulty and the later maintenance cost. Description of the Drawings

[0030] , a drone with fast disassembly, assembly and folding functions includes a drone frame and a drone fuselage 1. The drone frame and the drone fuselage 1 are fixedly connected through an arm connector 2. A buckle fixed end 4 is fixedly installed on the arm connector 2 by screws. Buckle movable ends 5 are fixedly assembled on both sides of the drone fuselage 1. A folding leg side plate 6 is fixed on the lower surface of the end of the drone frame. A leg 7 is movably installed inside the folding leg side plate 6. A leg fixing spring pin 8 for convenient limit is provided at the connection end of the leg 7 and the folding leg side plate 6.

[0022] For the purpose of fitting and assembling, the drone frame is composed of two first square carbon tubes 9 made of high-density carbon fiber fixed on the drone fuselage 1 and two second square carbon tubes 10 made of high-density carbon fiber with motors and rotors fixed at both ends.

[0023] For the purpose of fitting and adjusting the angle limit of the leg 7, two semi-circular grooves 11 matching the leg fixing spring pin 8 are opened on the folding leg side plate 6.

[0024] For the purpose of improving stability, the first square carbon tubes 9 on both sides of the drone fuselage 1 are horizontally embedded and fixedly installed. The installation angle between the first square carbon tube 9 and the second square carbon tube 10 is 90°.

[0025] For the purpose of adapting to drone fuselages 1 of different specifications and sizes, 6 mounting holes 12 are opened on the second square carbon tube 10 at the installation section of the arm connector 2.

[0026] For the purpose of improving the function expansion, an internal thread expansion hole 13 is opened at the bottom of the leg 7.

[0027] An LED warning light can be threadedly assembled at the bottom of the internal thread expansion hole 13, or a buoyancy platform can be threadedly fixed, which can facilitate mooring on the water surface.

[0028] The drone fuselage 1 integrates the circuit components and mounts of the drone.

[0029] Arm quick release:

[0030] The drone frame is connected to part of the drone fuselage 1 through the arm connector 2. When the drone needs to be stored, since the arm connector 2 is fixed to the first square carbon tube 9, only the lock cap at the movable end 5 of the buckle needs to be toggled. At this time, the movable end 5 of the buckle is unlocked from the fixed end 4 of the buckle. Then the arm connector 2 can be pulled out and placed on both sides of the drone fuselage 1. This solution can quickly disassemble and assemble the drone, greatly saving the disassembly and assembly time and simplifying the installation steps.

[0031] Realization of the quick folding structure of the tripod;

[0032] The folding tripod side plate 6 is connected to the tripod 7 through a rotating shaft, and the tripod can rotate around it in the unfixed state through this rotating shaft. And the folding tripod side plate 6 is fixed to the inner side of the arm square tube, just clamping the tripod 7. The semicircular grooves 11 at the bottom and one side of the folding tripod side plate 6 can just limit and fix the tripod 7 through the tripod fixing spring pin 8 when the tripod is unfolded and folded for storage. When the tripod needs to be folded, just press the tripod fixing spring pin 8. The spring device inside the tripod fixing spring pin 8 is stressed and contracts, and the tripod fixing spring pin 8 disengages from the circular groove. At this time, the tripod 7 changes from the fixed state to the free state that can rotate inward. Rotate the tripod 7 inward, and at this time the tripod 7 is folded.

[0033] Therefore, when the drone needs to be stored, just perform the above operations, fold the tripod 7, then pull out the frame and place the frame on one side of the fuselage, reducing the storage space.

[0034] Inspired by the above ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
