Abstract

A commercial vehicle cab roof structure comprises a front roof, a middle roof and a rear roof. The front roof, the middle roof and the rear roof are connected in sequence, the rear roof is higher than the middle roof, the middle roof is higher than the front roof, a skylight opening is formed in the middle of the middle roof, the front roof is connected with the middle roof through a front lap-joint edge and an upper middle lap-joint edge, the middle roof is connected with the rear roof through a lower middle lap-joint edge and a rear lap-joint edge, the front lap-joint edge and the upper middle lap-joint edge are connected to form a flow guide groove, the lower middle lap-joint edge and the rear lap-joint edge are connected to form a flow guide groove, a plurality of middle reinforcement ribs are arranged at the positions, close to the left side edge and the right side edge, of the middle roof, and a plurality of rear reinforcement ribs are arranged at the positions, close to the left side edge and the right side edge, of the rear roof. The commercial vehicle cab roof structure is low in production cost and low in welding difficulty, rain is not prone to being leaked, wind resistance is small, and energy consumption is low.

Description

technical field [0001] The invention belongs to the technical field of truck cabs, and in particular relates to a roof structure of a commercial vehicle cab, which is particularly suitable for reducing production costs and welding difficulty, and is not prone to rain leakage. Background technique [0002] The traditional truck cab roof is composed of one steel plate or two steel plates connected, and the two steel plates are usually welded at the ribs. Such top covers usually have the following deficiencies: [0003] 1. The size of the blank required for the top cover made of a steel plate is very large, difficult to purchase, and the cost is high. At the same time, the tonnage of the punching machine required to process the blank is very large, which increases the production cost again. In addition, when the top cover and the back wall are welded, due to the large size of the top cover, the welding tongs are not easy to get close to the welding edge, which increases the di...
