Abstract
The invention discloses a permanent-magnetic brake structure with like poles repellent at rail end of a catapult of a UAV (unmanned aerial vehicle). The permanent-magnetic brake structure mainly comprises a movable trolley base plate, a movable magnetic ring, a slide rail, an outer magnetic ring, a magnetic ring with like poles repellent and the like. The movable magnetic ring is arranged on the front of the movable trolley base plate and moves along the slide rail. The outer magnetic ring is used for fixing the magnetic ring. The magnetic ring with the like poles repellent is arranged at the tail of the slide rail and equal to the movable magnetic ring in diameter and concentric with the movable ring.
Description
Art
The present invention relates to the permanent magnetism two like magnetic poles repel each other brake structure of unmanned aerial vehicle ejector end, especially a kind of slide trolley can realize the device of the two like magnetic poles repel each other brake of brake rapidly at end.Belong to unmanned aerial vehicle ejector technical field.
Background technology
More than 50 kilograms, SUAV (small unmanned aerial vehicle) launches field, the domestic Electromagnetical ejector not being applicable to this type of unmanned plane, it is reported and only have the U.S. and Israel to have similar unmanned plane boost installation, the bungee ejector of domestic production can only launch the unmanned plane of boosting less than 50 kilograms, the unmanned plane of more than 50 kilograms weight can only rely on solid explosive rocket to carry out boosting, dangerous large, and carry and transport very difficult.
Summary of the invention
The permanent magnetism two like magnetic poles repel each other brake structure of unmanned aerial vehicle ejector end, keystone configuration comprises the parts such as the two like magnetic poles repel each other magnet ring of travelling car base plate, mobile magnet ring, slide rail, magnet ring outer ring and end and mobile magnet ring equal diameters and forms; Mobile magnet ring is arranged on the front portion of travelling car base plate, moves along slide rail, and magnet ring outer ring is used for fixing magnet ring; Slide rail end have one with the two like magnetic poles repel each other magnet ring of mobile magnet ring equal diameters, concentric with mobile magnet ring.
Detailed description of the invention
The permanent magnetism two like magnetic poles repel each other brake structure of unmanned aerial vehicle ejector end, keystone configuration comprises the parts such as the two like magnetic poles repel each other magnet ring of travelling car base plate, mobile magnet ring, slide rail, magnet ring outer ring and end and mobile magnet ring equal diameters and forms; Mobile magnet ring is arranged on the front portion of travelling car base plate, moves along slide rail, and magnet ring outer ring is used for fixing magnet ring; Slide rail end have one with the two like magnetic poles repel each other magnet ring of mobile magnet ring equal diameters, concentric with mobile magnet ring.
