Description

Technical Field

[0001] The utility model relates to the technical field of UAV parts, and specifically relates to a UAV landing gear that is convenient for folding and storage. Background Technique

[0002] Unmanned aerial vehicle, abbreviated as "UAV", with the English abbreviation "UAV", is an unpiloted aircraft controlled by radio remote control equipment and self - contained program control devices, or is completely or intermittently autonomously operated by an on - vehicle computer. Compared with piloted aircraft, UAVs are often more suitable for tasks that are "too dull, dirty or dangerous". UAVs can be divided into military and civilian applications according to application fields. In the military aspect, UAVs are divided into reconnaissance aircraft and target drones. In the civilian aspect, UAV + industry application is the real demand for UAVs; their applications in fields such as aerial photography, agriculture, plant protection, micro - self - shooting, express delivery, disaster relief, wildlife observation, infectious disease monitoring, mapping, news reporting, power line inspection, disaster relief, film and television shooting, creating romance, etc. have greatly expanded the uses of UAVs themselves. Developed countries are also actively expanding industry applications and developing UAV technologies; Unmanned aerial vehicle, abbreviated as "UAV" ("UAV"), is an unpiloted aircraft controlled by radio remote control equipment and self - contained program control devices. In fact, UAVs are a general term for unpiloted aircraft. From a technical perspective, they can be divided into: unmanned fixed - wing aircraft, unmanned vertical take - off and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi - rotor aircraft, unmanned parafoil aircraft, etc. Compared with piloted aircraft, it has the advantages of small volume, low cost, convenient use, low requirements for the combat environment, and strong battlefield survivability.

[0003] The application number is CN202320566502.5, which discloses a UAV folding landing gear structure, including a UAV, four connecting rods, four fixing blocks and four landing gears. The four connecting rods are respectively located around the UAV. The inner cavity of the fixing block contacts the surface of the connecting rod, and one side of the landing gear close to the fixing block is fixedly connected to the fixing block. By setting the cooperation of the UAV, connecting rod, fixing block, landing gear, placement groove, positioning mechanism and transmission mechanism, it solves the problem that the existing landing gear is connected and fixed to the UAV through multiple threaded components, which will consume a certain amount of time and energy of the user during the assembly process, so it is not convenient for the user to use. Moreover, the existing landing gear cannot achieve the effect of convenient folding and storage, so when storing the UAV, it will be affected by the landing gear, resulting in the UAV consuming too much storage space, thus reducing the convenience of the landing gear.

[0004] Although the above-mentioned utility model is connected and fixed to the drone through multiple threaded components, it will consume a certain amount of time and energy for the user to assemble during the assembly process. Therefore, it is not convenient for the user to use. Moreover, the existing landing gear cannot achieve the effect of convenient folding and storage. As a result, when storing the drone, it will be affected by the landing gear, leading to the situation that the drone consumes too much storage space, thus reducing the convenience of the landing gear. However, the disadvantage is that when the device is lifted and lowered, if the operation is not accurate, a certain amount of damage will be caused to the device during the downward impact force.

[0005] Therefore, it is necessary to install a shock-absorbing support leg component on the device, which can provide a certain buffering and shock-absorbing effect during use through the parts set inside the component when descending, avoiding the damage caused to the device by the uncontrolled downward impact force.
