Rocker arm type unmanned aerial vehicle ski buffering device

Abstract

The invention discloses a rocker arm type unmanned aerial vehicle ski buffering device. The rocker arm type unmanned aerial vehicle ski buffering device is composed an upper vehicle body connector, adamper, a ski bar and a rocker arm, wherein the upper vehicle body connector is arranged under a vehicle body and connected with the upper end of the damper through a damper-vehicle body connecting pin; a ski bar front connector is arranged in front of the vehicle body and connected with the ski bar through a ski bar-vehicle body connecting pin; the lower end of the damper is connected with the rocker arm through a damper-rocker arm connecting pin. During parachute landing, when the ski bar touches down, a ski bar support arm module can rotate around the ski bar front connector and a rocker arm-vehicle body connector under the action of support reaction force of the ground; during rotation, the ski bar support module can compress the damper, which then absorbs the sinking kinetic energy ofthe vehicle body to achieve buffering and damping effects; the ski is in a rocker arm type structure to achieve a long buffer stroke and reduce recovery overloading, and by means of high sideslip andground fiction, can absorb more impact energy to effectively protect safety of the vehicle body and equipment.

Description

technical field [0001] The invention relates to the technical field of UAV design, in particular to a rocker arm type UAV skid buffer device. Background technique [0002] Compared with traditional flying combat platforms, UAVs are small in size and highly concealed, and can go deep into the opponent's frontier to perform more dangerous tasks. Therefore, it is widely used in many fields such as enemy reconnaissance, electronic jamming, communication relay and air defense suppression. [0003] The sled shock absorption mode of UAV parachute recovery is not restricted by airport conditions, and has the characteristics of high battlefield mobility, simple control and strong site adaptability. It is currently the mainstream recovery method for most small and medium-sized UAV platforms. During the process of UAV parachute recovery and sled buffering, the UAV enters the sky above the predetermined recovery site, and the recovery parachute is inflated to open, stabilizing the sink...
