Abstract

The invention provides an aerial photography damping damper and relates to a damper. The problems that a damping ball utilized for an existing aircraft aerial photography damping mechanism is poor in load bearing capability and mechanical strength and potential safety hazards occur are solved. The damper comprises a viscous-elastic material filling layer, a damper upper shell plate, a damper lower shell plate, a fixed part and a buffer spring. The damper upper shell plate and the damper lower shell plate are fixedly connected through the fixed part, and a gap is formed between the outer side wall of the damper upper shell plate and the inner side wall of the damper lower shell plate. The gap is filled with the viscous-elastic material filling layer, the fixed part penetrates the damper upper shell plate and the center of the damper lower shell plate, the buffer spring sleeves the fixed part, the two ends of the buffer spring are fixed on the damper upper shell plate and the damper lower shell plate respectively, and the free length of the buffer spring is larger than the interval between the damper upper shell plate and the damper lower shell plate. The aerial photography damping damper is used for damping an aerial photography aircraft.

Description

Technical field [0001] The invention relates to a damper, in particular to an aerial photography shock-absorbing damper. Background technique [0002] High-frequency jitter is a huge problem for aerial photography aircraft. Existing aircraft will produce high-frequency vibrations of different frequencies during flight, resulting in serious aerial image distortion. The existing mechanical damping method generally achieves anti-shake by adding damping balls, that is, adding two layers of damping plates between the aircraft and the aerial photography gimbal, connecting with damping balls in the middle, and using the characteristics of damping balls to absorb shock , The shock-absorbing ball structure is such as figure 1 with figure 2 Shown. However, the hardness and load-bearing capacity of the shock-absorbing ball are poor, and it is not suitable when the camera equipment and the gimbal are too heavy. Secondly, the shock-absorbing ball is easy to wear and age, which will bring sa...
