The invention provides an undercarriage of an unmanned aerial vehicle and the unmanned aerial vehicle, and belongs to the field of unmanned aerial vehicles. The undercarriage comprises a plurality of supporting legs, and each supporting leg comprises a fuselage connecting rod, a cylinder, a valve rod and a one-way valve; one part of the valve rod is located in the cylinder, the other part of the valve rod is located outside the cylinder, the fuselage connecting rod is connected with the valve rod and the fuselage , and the one-way valve is located in the cylinder and divides an inner cavity of the cylinder into a first cavity and a second cavity in the axial direction. The one-way valve is configured to enable the damping effect of the fluid flowing from the first cavity to the second cavity to be greater than the damping effect of the fluid flowing from the second cavity to the first cavity. According to the invention, when the unmanned aerial vehicle lands, the valve rod pushes the one-way valve, fluid is squeezed into the second cavity from the first cavity, impact in landing is absorbed, and mechanical energy of the unmanned aerial vehicle is converted into internal energy of the fluid. Impact in the landing process of the unmanned aerial vehicle is effectively absorbed, so that bouncing and rolling of the unmanned aerial vehicle in the landing process are avoided, protection of the unmanned aerial vehicle is facilitated, and damage to the unmanned aerial vehicle in the landing process is avoided.

    本公开提供了一种无人机的起落架和无人机,属于无人机领域。该起落架包括多个支撑腿,支撑腿包括机身连接杆、筒体、阀杆和单向阀;阀杆一部分位于筒体中,另一部分位于筒体外,机身连接杆连接阀杆和机身,单向阀位于筒体中,将筒体的内腔沿轴向分隔为第一腔室和第二腔室,单向阀被配置为,使流体由第一腔室流向第二腔室时的阻尼作用大于流体由第二腔室流向第一腔室时的阻尼作用。该起落架在无人机降落时,阀杆推动单向阀,流体从第一腔室被挤入第二腔室,吸收降落中的冲击,将无人机的机械能转化为流体的内能。有效吸收无人机降落过程中的冲击,从而避免无人机降落过程中出现弹跳、翻滚的情况,有利于保护无人机,避免无人机在降落过程中受损。
