Description

Technical Field

[0001] The present invention relates to the technical field of aviation equipment manufacturing, and more specifically, to an embedded anti-vibration electromagnetic suction system for an unmanned helicopter. Background Art

[0002] When an unmanned helicopter performs a flight mission, it often needs to perform a dropping mission, and at present, an electromagnetic chuck is mainly used to solve the problem of dropping goods.

[0003] The conventional arrangement of the electromagnetic chuck is to directly fix the electromagnetic chuck on the frame. Since the fuselage often vibrates during the mission, causing the electromagnetic chuck to vibrate, the relative position between the electromagnetic chuck and the suction block changes, and in severe cases, it may even fall off.

[0004] To solve this problem, a new fixing method is needed to fix the electromagnetic chuck on the frame and at the same time be able to fix the position of the suction block so that the position of the suction block does not change, so that it can be applied to more occasions.

[0005] Therefore, how to provide an anti-vibration electromagnetic suction system with a simple structure and no position movement of the suction block is an urgent problem to be solved by those skilled in the art. Summary of the Invention

The limiting groove capable of fixing the suction block is set so that the position of the suction block will not change, solving the problem of possible position changes between the electromagnetic chuck and the suction block under large vibrations, and ensuring stability and safety.

[0012] Further, the middle part of the upper end of the fixing block is hollowed out, and the hollowed-out shape is rectangular, triangular or circular.

[0013] Preferably, the middle part of the upper end of the fixing block is hollowed out, the hollowed-out shape is triangular, and it is symmetrically arranged, with a total of 6 in 3 groups.
