AI Technical Summary

Technical Problem

The lack of filtering equipment in the air duct installation structure of new energy buses leads to blockage of the air inlet and insufficient external protection structure, which easily leads to damage to the air duct.

Method used

An installation structure including the main air duct and the secondary air duct pipe is designed. The main air duct surface is fixedly connected to the filter device, the filter device is equipped with a filter mesh and a replaceable filter plate frame, and the external connection of the secondary air duct is fixedly connected to the outer part of the secondary air duct. Protective plate, the protective plate can prevent damage and distribute the air outlet equidistantly at the bottom of the secondary air duct.

Benefits of technology

Effectively filter particulate matter in the air, prevent air outlets from being blocked, improve the service life of the air duct, and prevent damage to the air duct through protective plates, improving the safety of installation and use.

Abstract

The utility model discloses a passenger car air duct installation structure which comprises a main air duct pipe, the surface of the main air duct pipe is fixedly connected with a fixing ring, the interior of the fixing ring is fixedly connected with a filtering device, a groove is formed in the filtering device, a filtering plate frame can be installed in the groove, and a filtering net is fixedly connected in the filtering plate frame. The back face of the filtering device is fixedly connected with a combination plate, and the interior of the combination plate is connected with a combination bolt through threads. According to the passenger car air duct mounting structure, the filtering device is fixedly connected to the surface of the main air duct pipe, when air enters the air duct pipe, particulate matter mixed in the air can be filtered out through a filter screen in the filtering device, and the situation that an air outlet of an air duct is blocked due to the fact that excessive particulate matter or impurities are sucked in after long-term use is prevented; and meanwhile, the filtering plate can be replaced, so that the filtering plate is prevented from being blocked, and the filtering effect is relatively good.
