背景技术Background technique
无人机作为一种新型飞行器，以其体积小巧，便于操作，成本较低，便于完成特种任务而广泛应用于军事和民用领域。而多旋翼无人机由于可以垂直起降，便于悬停，稳定性较高等优点成为当下很受欢迎的无人机机种。但由于受天气影响，多旋翼无人机在飞行时很考验操作水平，操作工程中也较易出现坠机，降落不稳等状况，在此过程中起落架便起到了很大的保护作用。当下常用的起落架多无减震装置，或采用具有一般柔性的材料进行减震，减震效果不佳，少数具有减震装置的起落架轻量化设计不完善，增加了飞行负担。As a new type of aircraft, UAV is widely used in military and civilian fields because of its small size, easy operation, low cost, and easy completion of special tasks. The multi-rotor UAV has become a very popular UAV model due to its advantages of vertical take-off and landing, easy hovering, and high stability. However, due to the influence of the weather, multi-rotor drones are very challenging to operate when flying, and they are more prone to crashes and unstable landings during the operation process. During this process, the landing gear plays a great role in protection. Most commonly used landing gears do not have shock absorbing devices, or use generally flexible materials for shock absorbing, and the shock absorbing effect is not good. A small number of landing gears with shock absorbing devices are not perfect in lightweight design, which increases the flight burden.
