Title:
SHOCK ABSORBER, PAN-TILT AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/157633
Kind Code:
A1
Abstract:
Provided is a shock absorber (100), comprising a connecting portion (102) and buffering portions (101) respectively located on either end of the connecting portion, wherein the cross-sectional size of the shock absorber gradually decreases along the direction from a buffering portion to the connecting portion. Further provided are a pan-tilt (10) having the shock absorber, and an unmanned aerial vehicle (20). The middle portion of the shock absorber if of a smaller size than the two ends, thereby reducing the volume and the mass of the middle portion, such that the shock absorber has a higher flexibility and the inherent frequency corresponding to a second-order vibration mode of the shock absorber is greatly improved, thus avoiding the frequency coupling, in a high-frequency portion, between the shock absorber and a vehicle body. The shock absorber can effectively isolate the high-frequency vibration from the vehicle body so that the picture taken by a pan-tilt camera is sharper and more stable.
