Abstract

The invention discloses a sectional type outer plate of a rear door of an automobile. A sheet metal part is served as a main body; the outer plate is characterized in that the main body is divided into an upper section of the outer plate of the rear door and a lower section of the outer plate of the rear door from the upper edge of a rear windshield; a spoiler is integrally arranged on the upper section of the outer plate of the rear door; and a lower edge of the upper section of the outer plate of the rear door is fixedly connected with an upper edge of the lower section of the outer plate of the rear door. The upper section of the outer plate of the rear door is independently detached as a part; the stamping property is improved; the upper section can be stamped into a complex structure with the spoiler; a requirement for appearance effect of modeling is met; and the spoiler is integrated with the upper section of the outer plate of the rear door, so that the cost is lowered, the assembling is convenient, the restriction on modeling is reduced, and the spoiler is more beautiful and practical.

Description

A kind of sectional type automobile back door outside plate

Technical field

The present invention relates to motor vehicle bodywork component, be specifically related to a kind of sectional type automobile back door outside plate.

Background technology

On the automotive market, the tailgate outside plate of two-box automobile extensively adopts whole stamping forming structure at present, according to whether being with spoiler can be divided into following two types:

One type is the tailgate outside plate of band spoiler: adopt the tailgate outside plate topside of this structure more outstanding; Can't satisfy whole punch forming, therefore increase by a plastic spoiler on tailgate outside plate top through changing the moulding block form, the tailgate outside plate topside behind the increase spoiler is simplified greatly; Characteristic is that transition is milder; Can satisfy the outer stamping forming requirement of slab integral of tailgate, but owing to increased plastic spoiler, thereby cause integral vehicle cost to increase;

Another kind of type is not to be with the tailgate outside plate of spoiler: adopt the tailgate outside plate topside of this structure milder; And it is simple in structure; Could satisfy whole stamping forming requirement only so; But this structure produces very big constraint for the moulding meeting, can't satisfy moulding for the changeable demand of car load appearance.

Summary of the invention

The present invention is directed to the deficiency of prior art, propose a kind of simple in structure, be convenient to whole punch forming, lower-cost sectional type automobile back door outside plate.

A kind of sectional type automobile back door outside plate of the present invention, body is a sheet metal component, it is characterized in that: said body is divided into tailgate outside plate epimere and tailgate outside plate hypomere from the upper edge of rear seat windscreen, and said tailgate outside plate epimere has with it and is the spoiler of one; The bottom of said tailgate outside plate epimere captives joint with the top of said tailgate outside plate hypomere.

Further; The two ends of the bottom of said tailgate outside plate epimere are respectively equipped with a welding knock hole; The two ends, top of said tailgate outside plate hypomere are respectively equipped with a welding via hole, and it is corresponding that the following two welding knock holees of said tailgate outside plate epimere and two of said tailgate outside plate hypomere weld via holes.

Further, the top of said tailgate outside plate hypomere is provided with the landing edge of 25-30mm, and the bottom of said tailgate outside plate epimere captives joint with the top of said tailgate outside plate hypomere through spot welding.

The present invention compares with prior art and has the following advantages: because tailgate outside plate epimere is split as parts separately, improved punching performance, enabled to strike out the labyrinth of band spoiler, satisfied the demand of moulding to appearance; Spoiler and tailgate outside plate epimere are combined together, but one side cost-cutting, convenient for assembly can reduce the constraint to moulding on the other hand, makes it more attractive in appearance, practical.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is an assembling scheme drawing of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further described.

Referring to Fig. 1, Fig. 2 and a kind of sectional type automobile back door outside plate shown in Figure 3, body is a sheet metal component; Said body is divided into tailgate outside plate epimere 1 and tailgate outside plate hypomere 2 from the upper edge of rear seat windscreen, said tailgate outside plate epimere 1 has with it and is the spoiler 5 of one; The two ends of the bottom of said tailgate outside plate epimere 1 are respectively equipped with a welding knock hole 3; The two ends, top of said tailgate outside plate hypomere 2 are respectively equipped with a welding via hole 4, and it is corresponding that the following two welding knock holees 3 of said tailgate outside plate epimere 1 and two of said tailgate outside plate hypomere 2 weld via holes 4.

Further, the top of said tailgate outside plate hypomere 2 is provided with the landing edge of 25-30mm, and the bottom of said tailgate outside plate epimere 1 captives joint with the top of said tailgate outside plate hypomere 2 through spot welding.

Because two-part fractionation of body and spot welding position can be blocked by the black surround of rear seat windscreen just, therefore appearance is not produced harmful effect.
