Roof structure, manufacturing method thereof, and vehicle

Abstract

The invention provides a vehicle roof structure, a manufacturing method thereof, and a vehicle, and relates to the technical field of vehicles. The vehicle roof structure comprises a top cover, an upper surrounding cover plate and an upper vehicle body assembly, a groove is formed in the upper side of the upper surrounding cover plate, the upper surrounding cover plate is divided into two parts bythe groove, one side of the groove is an upper surrounding cover plate body, and the other side of the groove is an upper surrounding cover plate protruding part; the front edge of the top cover is bent downwards and extends into the groove, and the position, close to the front edge, of the bottom face of the top cover is tightly attached to the upper surface of the protruding portion of the upper surrounding cover plate; and the upper vehicle body assembly comprises a first protruding part extending upwards, and the outer face of the first protruding part is tightly attached to the lower face and the end face of the protruding part of the upper surrounding cover plate and the bottom face of the upper surrounding cover plate. By changing the modeling structure of the car roof and combining the bonding of the upper layer and the lower layer and the height difference degree, the water leakage prevention function is guaranteed, the water leakage problem is essentially solved, meanwhile,the cost is saved, and the production efficiency is improved.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, in particular to a roof structure, a manufacturing method and a vehicle. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] At present, the traditional way of connecting the car roof and the side wall is to weld them together by electric welding, then apply electric welding sealant, and finally leave a large gap. In order to solve the problem of water leakage, a sealing strip must be attached to seal it. Then, the gap left by electric welding is filled with expansion glue, and further waterproofing is completed. [0004] The inventors of the present disclosure found that, with the prolongation of the service time of the vehicle, the roof of this traditional roof structure tends to loosen, and there will be roaring noises inside the compartment; The ...

Problems solved by technology

[0004] The inventors of the present disclosure found that, with the prolongation of the service time of the vehicle, the roof of this traditional roof structure tends to loosen, and there will be roaring noises inside the compartment; The two sides of the top cover are twisted, and the top cover is prone to abnormal noise, resulting in a decrease in the strength of the top cover
