The invention belongs to the technical field of unmanned aerial vehicle accessories, and particularly relates to a bionic undercarriage suitable for rapid landing and an unmanned aerial vehicle, the bionic undercarriage comprises a claw, the claw comprises a hinge arm, a claw body and a claw tip, the claw body is hinged to the claw tip, the claw body is hinged to the hinge arm, a third hinge shaft is arranged at the lower end of an auxiliary arm, and the auxiliary arm is hinged to the middle of the hinge arm; a first protruding block is arranged on the hinge arm, a first penetrating hole is formed in the first protruding block, and the third hinge shaft is located between the first protruding block and the second hinge shaft. A second protruding block is arranged on the claw tip, a second penetrating hole is formed in the second protruding block, and the second protruding block is located between the first hinge shaft and the second hinge shaft. The free end of the third linear tension mechanism sequentially penetrates through the first penetrating hole and the second penetrating hole and is fixedly connected with the claw tip. The landing gear aims at solving the problems that when an unmanned aerial vehicle lands due to the structural defects of an existing landing gear, large recoil force is caused to the landing gear, and even the structure of the unmanned aerial vehicle is damaged seriously.

本发明属于无人机配件技术领域，具体涉及一种适用于快速降落的仿生起落架及无人机，包括：脚爪，脚爪包括铰接臂、爪体和爪尖，爪体与爪尖铰接，爪体与铰接臂铰接，副臂的下端设有第三铰接轴，副臂与铰接臂的中部铰接；铰接臂上设有第一凸块，第一凸块开设有第一穿孔，第三铰接轴位于第一凸块和第二铰接轴之间；爪尖上设有第二凸块，第二凸块开设有第二穿孔，第二凸块位于第一铰接轴和第二铰接轴之间；第三线性拉力机构，第三线性拉力机构的自由端依次穿设在第一穿孔和第二穿孔内、且与爪尖固定连接。其目的是：解决现有的起落架结构缺陷导致的无人机降落时，对起落架造成很大的反冲力，严重的甚至对无人机的结构造成损伤的问题。
