The invention relates to the technical field of multi-rotor unmanned aerial vehicles, in particular to a multi-rotor unmanned aerial vehicle with an anti-collision function, the multi-rotor unmanned aerial vehicle comprises a vehicle body, rotors and a connecting plate, the rotors are mounted on the outer wall of the vehicle body, the connecting plate is mounted at the bottom of the vehicle body, a connecting assembly is mounted at the bottom of the connecting plate, and a buffer assembly is mounted at the bottom of the connecting plate. The buffer assembly comprises a lifting rod, a bent rod, a lifting plate and a spring, the lifting rod is fixedly connected to the bottom of the connecting plate, the bent rod is installed at the bottom end of the lifting rod, the lifting plate is installed in the bent rod, and the spring is fixedly connected to the bottom of the inner wall of the bent rod. According to the multi-rotor unmanned aerial vehicle with the anti-collision function, when the multi-rotor unmanned aerial vehicle descends, impact force can act on the bent rods, the lifting rods can slide into the bent rods under the gravity action of the vehicle body, and due to the fact that the bent rods are filled with damping oil and springs, the gravity and the impact force can be absorbed by the damping oil and the springs, and the buffering effect is achieved.

    本发明涉及多旋翼无人机技术领域,具体为一种具有防撞功能的多旋翼无人机,包括机体、旋翼和连板,所述旋翼安装于机体的外壁,所述连板安装于机体的底部,所述连板的底部安装有连接组件,所述连板的底部安装有缓冲组件,所述缓冲组件包括升降杆、弯杆、升降板和弹簧,所述升降杆固定连接于连板的底部,所述弯杆安装于升降杆的底端,所述升降板安装于弯杆的内部,所述弹簧固定连接于弯杆的内壁底部。该具有防撞功能的多旋翼无人机,在下降时,冲击力会作用至弯杆,而升降杆会在机体的重力作用下滑入弯杆的内部,由于弯杆的内部填充有阻尼油和弹簧,重力与冲击力会被阻尼油和弹簧吸收,从而起到缓冲的效果。
