Description

Unmanned aerial vehicle filter

Technical Field

The utility model belongs to the technical field of filters, and particularly relates to a filter for an unmanned aerial vehicle.

Background

With the development of scientific technology, the unmanned aerial vehicle has been widely applied and gradually becomes one of the main shooting devices. However, the applicant finds that the image shot by the camera originally arranged on the unmanned aerial vehicle has a single effect and cannot meet the requirements of users (especially the shooting enthusiasts), and later finds that filters specially used for the unmanned aerial vehicle appear in the market, are composed of filter supports and filter lenses and have the following defect problems:

1. in the existing unmanned aerial vehicle filters, a filter lens is arranged on the back surface of a filter support, and the peripheral edges of the filter lens are fixedly connected with the back surface of the filter support in a sticking mode; because the bonding surface between the peripheral edge of the filter lens and the back surface of the filter support is small (the bonding surface is an annular surface with the width of about 1.5 mm), the bonding force is not strong, when the filter is installed on an unmanned aerial vehicle or the filter installed on the unmanned aerial vehicle is cleaned and maintained, the filter lens is often separated from the filter support or even falls off due to overlarge pressure applied to the filter lens from the front surface, and the fixing effect between the filter lens and the filter support is unstable and unreliable;

2. the structure at the filter support back is installed to these unmanned aerial vehicle filters now adoption filter lens, has increaseed the processing degree of difficulty of filter support on the one hand, and on the other hand has also increased the equipment degree of difficulty of filter lens and filter support.

Therefore, the applicant thinks that the adhesive force between the filter lens and the filter support can be improved, specifically, the adhesive surface between the filter lens and the back surface of the filter support is increased (the width of the adhesive surface is about 2.0 mm), although a certain effect is achieved by the scheme, the risk of loosening still exists due to the fact that pressure is repeatedly applied to the filter lens from the front surface for a long time or for multiple times, and after the scheme is adopted, the volumes of the filter lens and the filter support need to be increased on the premise that the same parameters such as the filter effect range are not changed, so that the weight and the cost of the filter are increased.
