Abstract

The invention provides a lifting device for an onboard optoelectronic platform, belongs to the technical field of aviation optoelectronics, and solves the problems of unstable structure and poor rigid connectivity of the existing lifting device for the onboard optoelectronic platform. The device comprises a gear bank, a motor, a substrate, a lifting plate, four screws, four toothed belt wheels and a toothed synchronous belt, wherein the gear bank comprises a driving gear and a driven gear; the lifting plate is connected with the four screws; upper and lower ends of the four screws are connected with the substrate; the motor is installed on the substrate; the driving gear is arranged on the motor; the driven gear is connected with one of the four screws; the toothed belt wheels are connected with the upper ends of the screws; the toothed synchronous belt is wound on the four toothed belt wheels; when the motor is operated, the driven gear drives one of the four screws to rotate, then the toothed synchronous belt drives the four toothed belt wheels to rotate synchronously, and the rotation movement of the four screws is changed into up-and-down movement of the lifting plate. The lifting device disclosed by the invention is compact in structure, easy to install and stable.

Description

technical field [0001] The invention belongs to the technical field of aviation optoelectronics, and in particular relates to a lifting device for an airborne optoelectronic platform. Background technique [0002] The airborne optoelectronic platform is the most commonly used cutting-edge technology in modern weapon systems in the field of space optoelectronics, and is mainly used in aerial reconnaissance systems. In order to reduce wind resistance and protect the platform, some photoelectric platforms are equipped with a lifting mechanism to ensure that the photoelectric platform can rise and fall freely inside and outside the belly. [0003] Due to the limitation of volume and weight, the miniaturization, light weight and high rigidity of the lifting mechanism are always the main issues considered by designers. In the prior art, most of the lifting mechanisms used for airborne optoelectronic platforms adopt the upper, middle and lower three-layer plate structure to achiev...
