Abstract

The invention provides an omni-directional damping single-freedom-degree photoelectric reconnaissance platform device and relates to the technical field of low-altitude remote sensing and aerial photography. The omni-directional damping single-freedom-degree photoelectric reconnaissance platform device solves the problem that an existing photoelectric reconnaissance platform device cannot be suitable for a micro-miniature multi-rotor unmanned aircraft. The omni-directional damping single-freedom-degree photoelectric reconnaissance platform device comprises a supporting frame, a supporting plate connected with the supporting frame, an omni-directional damping mechanism which comprises a base connected with the supporting frame, a substrate fixedly connected with an aircraft, a first nitrogen spring, a fourth nitrogen spring, a fifth nitrogen spring, a second nitrogen spring, a third nitrogen spring, a pitching rotation mechanism which comprises a driving motor fixed on the supporting frame, a crank connected with the driving motor, a first connecting rod connected with the crank, a second connecting rod connected with the first connecting rod, one ends of the first nitrogen spring, the fourth nitrogen spring and the fifth nitrogen spring are connected with the substrate, the other ends of the first nitrogen spring, the fourth nitrogen spring and the fifth nitrogen spring are connected with the base, one ends of the second nitrogen spring and the third nitrogen spring are connected with the base, the other ends of the second nitrogen spring and the third nitrogen spring are connected with the substrate, and the second connecting rod is respectively connected with the supporting plate and a first connecting block respectively. The omni-directional damping single-freedom-degree photoelectric reconnaissance platform device can effectively eliminate vibration in any direction, improves imaging quality, and is simple in structure, low in cost and high in reliability.

Description

technical field [0001] The invention relates to the technical field of low-altitude remote sensing and aerial photography, in particular to an omnidirectional shock-absorbing single-degree-of-freedom photoelectric reconnaissance platform device. Background technique [0002] Compared with traditional fixed-wing aircraft, multi-rotor unmanned aerial vehicles have developed vigorously due to their unrestricted landing location and fixed-point hovering, and have been widely used in aerial photography, reconnaissance, search and rescue and other fields. Micro multi-rotor unmanned aerial vehicles have weak wind resistance and low steady-state accuracy. Especially when hovering and observing, the body of the aircraft will vibrate in different directions. If these jitters are not reduced, it will make it difficult for the photoelectric imaging equipment to stabilize. resulting in poor image quality. [0003] The photoelectric reconnaissance platform, as the carrier of the photoele...
