Commercial vehicle top cover, commercial vehicle and assembling method

Abstract

The invention relates to a commercial vehicle top cover, a commercial vehicle and an assembling method. The commercial vehicle top cover comprises a front top cover; the rear top cover is arranged opposite to the front top cover; the middle top cover is in lap joint between the front top cover and the rear top cover; the side top cover is in lap joint among the front top cover, the rear top cover and the middle top cover, the middle top cover is located at the top of the side top cover, the side top cover comprises a main body and an extension section integrally formed with the main body, the extension section is formed by extending from the main body to the direction close to the middle top cover, and the extension section is in lap joint with the middle top cover. And an air inlet channel sinking table is arranged on the extension section. By arranging the integrally-formed extension section on the side top cover, when the side top cover is widened on the basis of the original side top cover, the air inlet channel does not need to be arranged across the side top cover and the middle top cover and can be completely arranged on the side top cover, so that the problem that the lap joint surfaces of the side top cover and the middle top cover are provided with steps and cannot be attached to each other is solved; the top cover sealing problem caused by an overhead air inlet channel is solved.

Description

technical field [0001] The invention relates to the field of commercial vehicles, in particular to a commercial vehicle roof cover, a commercial vehicle and an assembling method.
