Automatic disengaging device for charging mooring line of multi-rotor unmanned aerial vehicle

Abstract

The invention discloses an automatic disengaging device for a charging mooring line of a multi-rotor unmanned aerial vehicle. The automatic disengaging device comprises a device outer shell fixedly mounted on the unmanned aerial vehicle, a fixed electrode connected with the device outer shell and provided with an electromagnet and a movable electrode provided with a permanent magnet; the fixed electrode is connected with a vehicle-mounted battery of the unmanned aerial vehicle; an electromagnet control circuit which controls the electromagnet to be powered on and off is arranged on a control circuit board of the unmanned aerial vehicle; the movable electrode is connected with the charging mooring line; and the charging mooring line is connected with a ground power supply. According to the automatic disengaging device, an electromagnet spring center structure and a permanent magnet spring center structure are combined, the function of remote control disengaging of the charging mooring line of the unmanned aerial vehicle is achieved, it is guaranteed that the unmanned aerial vehicle can continuously fly in a certain range, and the requirement that in special needs, the charging line is disengaged, and flying is continued through the internally-arranged battery is also met.

Description

technical field [0001] The invention relates to unmanned aerial vehicle technology, especially unmanned aerial vehicle charging technology. Background technique [0002] The endurance of multi-rotor unmanned aerial vehicles is a key technical issue affecting the application of unmanned aerial vehicles. In order to improve the battery life, the scheme of frequently returning to the voyage to replace the backup battery is usually adopted at present. However, if the unmanned aerial vehicle is required to fly in a large area, frequent battery replacement is not only time-consuming and labor-intensive, but also poor in operation effect. In order to make the multi-rotor unmanned aerial vehicle have a longer battery life, a built-in large-capacity high-energy-density lithium battery is generally used as a power source, but a larger-capacity battery increases the load on the body, which not only limits the maneuverability of the unmanned aerial vehicle, It also increases power con...
