Abstract

The utility model discloses an overlapping structure of an automobile roof, wherein the automobile roof is provided with an overlapping surface and is overlapped above a rear wall metal plate, the overlapping surface is in a strip shape, one side of the overlapping surface, which is contacted with the rear wall metal plate, is pressed with a plurality of concave rectangular small surfaces in a mould pressing mode, and the small surfaces are uniformly arranged in the length direction of the overlapping surface. By adopting the utility model, the small faces are arranged on the lapping surfaces, so that the installation of the car roof and the rear wall metal plate is convenient; a plurality of small faces are pressed through a mould pressing process, so that the structural strength of the lap joint face is improved, namely the structural strength of the car roof is improved.

Description

Lap joint structure of automobile roof

Technical Field

The utility model relates to a lap joint structure, in particular to an automobile roof.

Background

With the trend that the engine cabin of a mini-truck is more and more used, the mini-truck is used as a ceiling which is the largest-sized product of the interior trim part of an automobile, plays a role of playing a great role in the interior trim, and a lap joint structure of a hard top and a metal plate of the rear periphery of an automobile body is a part which needs to be researched in the design of the whole automobile in the earlier stage. The existing roof structure has the problem of insufficient strength.

Disclosure of Invention

The utility model aims to: the problem of roof intensity is not enough among the prior art is directed at, provides the overlap joint structure of high strength's car roof.

In order to realize the purpose of the utility model, the utility model provides the following technical scheme:

the utility model provides an overlap joint structure of car roof, the roof is equipped with faying surface and overlap joint and encloses the panel beating top after, and the overlap joint is personally submitted long banding, and the faying surface has a plurality of recessed rectangle form facets through the suppression of mould pressing mode with one side of enclosing the panel beating contact after with, and the facet is at the length direction align to grid of faying surface.

By adopting the technical scheme, the small faces are arranged on the overlapping surfaces, so that the car roof and the rear wall metal plate can be conveniently installed; a plurality of small faces are pressed through a mould pressing process, so that the structural strength of the lap joint face is improved, namely the structural strength of the car roof is improved.

Furthermore, two side edges of the car roof are bent downwards, and the included angle between the bent edges and the edges of the lap joint surfaces is 85 degrees. The structure is convenient to process, simple in process and smooth in the boundary of the car roof.

Further, the vehicle roof is made of GMT plates. The GMT sheet material is adopted, so that the weight of the car roof is effectively reduced, and meanwhile, the cost is effectively reduced.

Further, the size of the facet was 12mmX80mm, and the width of the overlapping surface was 12 mm. The width of the overlapping surface is the same as that of the small surface, so that the interference condition of the overlapping part of the vehicle roof and the rear wall metal plate is reduced.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that: the small faces are arranged on the lapping surfaces, so that the car roof and the rear wall metal plate can be conveniently installed; a plurality of small faces are pressed through a mould pressing process, so that the structural strength of the lap joint face is improved, namely the structural strength of the car roof is improved.
