Description

Dustproof Structure of Wireless Video Equipment {STRUCTURE FOR PREVENTING VIBRATION OF WIRELESS PHOTOGRAPHING DEVICE}

The present invention relates to a dustproof structure of a wireless imaging apparatus, and more particularly, to a dustproof structure of a wireless imaging apparatus provided in an unmanned helicopter for mounting a photographing apparatus such as a camera or a camcorder to an unmanned helicopter.

In general, music videos, dramas, movies, etc. are different depending on the angle of shooting, so that the background and actors in the surroundings properly harmonized if you shoot from a variety of angles can maximize the impression of the viewers.

In particular, when the actor is photographed at an angle looking downward from the upper side, in the past, a camera or the like was photographed by a long tool, which has a problem of limitation of length and limitation of operation.

In order to solve this problem, a method of taking an image by attaching a photographing device such as a camera or a camcorder to an unmanned helicopter has been devised.

Korean Utility Model Registration No. 20-0213899 "Dustproof Structure of Wireless Imaging Apparatus", Korean Utility Model Registration No. 20-0197987 "Dustproof Structure of Wireless Imaging Apparatus", etc. As a representative example, a technique for mounting a photographing apparatus to a helicopter but preventing a vibration of the helicopter from being transmitted to the photographing apparatus is disclosed.

However, the above-described conventional techniques used dustproof rubber to prevent the vibration of the helicopter from being transmitted to the photographing apparatus. This dustproof structure has advanced in terms of dustproofing of the unmanned photographing apparatus, but has a disadvantage in overlooking the characteristics of the unmanned helicopter.

The engine speed of a conventional unmanned helicopter is 15,000 RPM, which rotates at a very high speed to generate high frequency vibration. In addition, the anti-vibration structure of the photographing apparatus is not only to prevent the one-way vibration generated from the unmanned helicopter, but also to suppress the vibration for all three axes of the X, Y, and Z axes.

Considering the characteristics of such an unmanned helicopter, the above-described conventional techniques adopt a relatively high damping coefficient of anti-vibration rubber, which is not only unsuitable for high frequency vibration of the unmanned helicopter, but also suppresses only one-way vibration.

Accordingly, an object of the present invention is to insert a fluid damper having a low damping coefficient to prevent high frequency vibration generated from an unmanned helicopter from being transferred to a photographing apparatus mounting plate on which a photographing apparatus is mounted, thereby performing photographing accuracy.
