Mechanical self-locking type unmanned aerial vehicle electromagnetic launching device

Abstract

The invention discloses a mechanical self-locking type unmanned aerial vehicle electromagnetic launching device which comprises an electromagnet disc, a bearing armature matched with the electromagnet disc and a backup force bearing mechanism. The backup force bearing mechanism is hollow and is arranged outside the electromagnet disc in a sleeving mode, and the upper end of the backup force bearing mechanism and the upper end of the electromagnet disc are both fixed to the machine body structure; the bearing armature comprises a suction cup, and a force bearing column is arranged on the lower portion of the suction cup and used for hanging goods. The side face of the backup force bearing mechanism is provided with a sliding-out opening, the bottom of the backup force bearing mechanism is provided with a through groove, the suction cup bearing the armature is installed into the backup force bearing mechanism from the sliding-out opening, the force bearing column penetrates through the through groove, the upper surface of the suction cup is matched with the electromagnet disc, and the lower surface of the suction cup is matched with the inclined face of the sliding-out opening. A locking mechanism used for fixing the position of the suction cup is further arranged in the backup force bearing mechanism. Under the condition that the electromagnet fails or the unmanned aerial vehicle is powered off, goods hung on the unmanned aerial vehicle are not unhooked, and the safety and reliability of the electromagnet type throwing device are improved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle delivery, in particular to a mechanical self-locking electromagnetic delivery device for unmanned aerial vehicles. Background technique [0002] The drone delivery device is generally composed of two main parts: a load-bearing mechanism and a release mechanism. The load-bearing mechanism is used to fix the cargo, bear the weight of the cargo and overload during flight; the release mechanism is used to decouple the cargo from the load-bearing mechanism to realize material delivery or Uninstall function. [0003] For example, the mechanical delivery mechanism: the hook lock structure connected to the goods acts as a force-bearing mechanism; the stepping motor drives the opening and closing mechanism to release the hook lock connected to the goods to realize the delivery function. Electromagnetic feeding mechanism: The electromagnetic sucker also undertakes the functions of the load-bearing me...

Problems solved by technology

[0004] However, the safety and reliability of the pure electromagnet type feeding device are not high

In addition to the failure risk of the electromagnet itself, the electromagnet is restricted by the power supply, and the power supply fluctuation or power failure will affect the normal operation of the electromagnet.

During the flight, if the electromagnet delivery device fails, the cargo will fall off directly, which will pose a safety threat to personnel and building facilities under the flight route.

[0005] At present, most of the inventions of electromagnet-type delivery devices only use the principle of electromagnets, and do not consider the safety and reliability of this type of delivery device.
