The invention relates to a damper, an unmanned aerial vehicle foot stool and an unmanned aerial vehicle. The damper comprises a cylinder body, a fixing part fixedly connected to the interior of the cylinder body, a pushing piece configured to axially move in the cylinder body, an elastic piece elastically propped between the fixing part and the pushing piece, and a damping piece configured to move along the axial direction along with the pushing piece; the damping piece is provided with a conical lip, the conical lip is provided with a first end and a second end along the axial direction, the diameter of the first end is larger than that of the second end, the first end is closer to the fixing part than the second end, and the first end abuts against the inner wall of the cylinder body and is in sliding friction with the inner wall when moving along with the pushing piece. Therefore, the frictional resistance between the damping piece and the inner wall of the cylinder body in the axial movement process of the damping piece along with the pushing piece can play a damping role and consume kinetic energy so as to buffer the impact force borne by the damper, the damping of the damping piece is large when the damping piece moves towards the fixed part, and the damping of the damping piece is small when the damping piece moves away from the fixed part, and rapid rebound can be realized while the buffering effect is realized.
Description
technical field [0001] The present disclosure relates to the technical field of mechanical vibration, and in particular, to a damper, a drone tripod and a drone. Background technique [0002] The moving parts of robots, drones and other products need to use dampers to slow the vibration when they are impacted. Dispersion, thereby preventing the aircraft from jumping and tipping during landing, and improving the safety of the aircraft. The damper in the related art adopts a structure such as elastic rubber, which can play a good damping effect on the collision vibration, but it is not suitable for occasions like drone tripods that need to rebound quickly after damping. , and the current damper has a complex structure and takes up a large space. Contents of the invention [0003] The purpose of the present disclosure is to provide a damper, a drone tripod equipped with the damper, and a drone equipped with the drone tripod, so as to at least partly solve the problems exist...
