Abstract

The utility model provides a roof covering of a motor vehicle, which is characterized in that the covering consists of two rolling plates, wherein the two rolling plates are welded together, and rolling ribs stretching in the length direction are arranged on the rolling plates.

Description

The vehicle roof covering

Technical field:

The utility model relates to a kind of vehicle roof covering.

Background technology:

As shown in Figure 1, the covering 1A of at present common vehicle roof generally passes through the welding process spicing forming type by polylith cold-reduced sheet 1B, the Top Skin of this structure is in the splicing manufacturing process, weld seam is many, the bulk deformation and the deflection that cause easily covering are larger, follow-up rectification work capacity is difficulty greatly and relatively, intensity on covering has larger impact, and, in the use procedure in later stage, too much weld seam very easily is subject to the impact of rainwater and the corrosion phenomenon, and the service life of Top Skin is lower.

The utility model content:

For solving above-mentioned technical matters, the vehicle roof covering that the utility model provides a kind of to be convenient to make, intensity is reliable and service life is long.

The technical solution of the utility model is, a kind of vehicle roof covering with following structure is provided, and described covering is comprised of two rolling plates, welds between two rolling plates, and rolling plates is provided with the roll extrusion muscle that extends along its length.

Described roll extrusion muscle is arc.

After adopting said structure, the utlity model has following advantage:

Substitute original cold-reduced sheet with rolling plates, cold-reduced sheet shorter, rolling plates is then long, can satisfy the demand of bodywork length, so just only need two rolling plates to get final product, so just can reduce the quantity of weld seam, be conducive to reduce the deflection of covering, in down-stream, just saved a large amount of trimmings, it is comparatively convenient to make, and the less and roll extrusion muscle structure of skin morph amount all is conducive to improve bulk strength, and after weld seam lacked, the possibility of then being corroded by rainwater also just reduces, and the life-span of covering can be improved.

Description of drawings:

Fig. 1 is the topology view of at present common vehicle roof covering;

Fig. 2 is the plan structure scheme drawing of the utility model vehicle roof covering;

Fig. 3 is the section drawing of the utility model vehicle roof covering;

The specific embodiment:

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Such as Fig. 2, shown in Figure 3, the utility model vehicle roof covering, described covering 1 is comprised of two rolling plates 2, and welding between two rolling plates 2 all is provided with the roll extrusion muscle 3 that extends along its length on every rolling plates 2.Roll extrusion muscle 3 can play the effect of strengthening intensity.

As preferably, it is arcuate structure that described roll extrusion muscle 3 adopts cross-sectional planes.

Claims (2)

1. vehicle roof covering, it is characterized in that: described covering (1) is comprised of two rolling plates (2), welding between two rolling plates (2), rolling plates (2) is provided with the roll extrusion muscle (3) that extends along its length.

2. vehicle roof covering according to claim 1 (1), it is characterized in that: described roll extrusion muscle (3) is arc.
