Abstract
The invention is a rear lower cover plate of whole side wall shell of a car body, and it is of a box drawn component structure, its four side surfaces have drawn flangings, the corners of the box draw component are designed with openings, locally drawn, the drawing heights of the corners are smaller than those of the four drawn flangings, one drawn flanging of the box drawn component is lap-jointed and spot-welded with the side wall shell and the other three drawn flangings are spot-welded with various accessories in the rear of the side wall.
Description
Technical field
The invention relates to motorcar body outer covering piece gusset rear lower structure of cover plate.
Background technology
In the design of the side-wall outer-plate of the vehicle exterior cladding element that adopts the steel plate body structure, extensively adopted unitary side to enclose meter.This be the complete, attractive in appearance of vehicle body external form just, and external mass stablize, reliably provide great assurance.The various car major parts of countries in the world have all been taked whole side-wall outer-plate design at present.But because the vehicle body outward appearance is ever-changing, the variation of body shape may make the gusset external structure very complicated.And being subjected to the limitation of Sheet Metal Forming Technology level, the functional limitation of body material all can cause some part of a part of vehicle-body outer panel integral body to create.Particularly have changeable surface modeling, can not realize all that unitary side encloses meter for external structure behind the gusset of some car.
Summary of the invention
The outside curved-surface structure of gusset that The present invention be directed to car is complicated and changeable, can not realize the Integratively side-wall outer-plate, and the rear lower cover plate of a kind of car body integral side-wall outer-plate of design-calculated has been guaranteed the realization of unit body design model characteristics.
Technical scheme of the present invention is as follows:
A kind of rear lower cover plate of car body integral side-wall outer-plate, it is a box type drawn component structure, there is the flange that draws of the formation of drawing four sides, the bight of M face is wrinkling in the punching course, four jiaos of box type drawn component have been designed to opening, but still be designed to the local elongation structure, but the bight stretching highly is significantly less than four height that draw flange, to guarantee the integraty of lid surface styling design.This box type drawn component with individual flange and the side-wall outer-plate overlap joint that draws, connect with spot welding, three draw flange and are connected with spot welding with each correlated parts of gusset rear portion respectively in addition.
This body side wall rear lower cover plate is the outer part that covers of motorcar body gusset, with after side-wall outer-plate is connected, makes it to become the extension of side-wall outer-plate.
The invention has the advantages that:
1, because this part is the part of the outer covering of body side wall, any technology knock hole location can not be arranged, for guarantee with the accuracy and the reliability of the welding of side-wall outer-plate, exterior design is become the box type draw structure, like this when welding process is located with external form, just can reach the welding precision of demand, solve the difficult point that the motorcar body side-wall outer-plate is implemented at the design and processes of rear lower extending part;
2, adopt the box type to draw structure, guarantee that this part is connected with the spot welding of complex parts on every side, can guarantee little, the neat lines of outward appearance weld gap of connecting portion, outward appearance is better than with project organizations such as screw connections.
3, on structure design, take four jiaos of gaps (prevent cracking), but still the design that keeps the bight shallow recessing, reduce as far as possible or avoided producing in the production defective, can guarantee the A level surface of product appearance preferably.
Description of drawings
Fig. 1 is the block diagram of gusset rear lower cover plate;
Fig. 2 is the overlap joint scheme drawing of gusset rear lower plate shaft and side-wall outer-plate;
The specific embodiment
Referring to Fig. 1, the rear lower cover plate of car body integral side-wall outer-plate is a box type drawn component structure, its four sides have four of the formation of drawing to draw flange E, F, G, H, bight for fear of punching course cover plate face is wrinkling, four jiaos of A, B, C, D of box type drawn component have been designed to opening, opening still is designed to the local elongation structure, and the stretching in bight height h is significantly less than four height h` that draw flange, can guarantee the integraty of lid surface styling design like this.
Referring to Fig. 2, draw flange F and side-wall outer-plate J overlap joint, connect with spot welding, K is the spot welding position, and I is a gusset rear lower cover plate, and three draw flange E, G, H and are connected with spot welding with each correlated parts of gusset rear portion respectively in addition.
Claims (1)
1, a kind of rear lower cover plate of car body integral side-wall outer-plate, it is characterized in that it is a box type drawn component structure, there is the flange that draws of the formation of drawing four sides of described box type drawn component, four jiaos of box type drawn component have been designed to opening, four jiaos of described opening is the local elongation structure, the bight stretches and highly is lower than four height that draw flange, one of this box type drawn component draws flange and side-wall outer-plate overlap joint, connect with spot welding, three draw flange and are connected with spot welding with each part of gusset rear portion respectively in addition.
