Abstract
The utility model relates to the structural field of automotive body, in particular to a novel automotive body which comprises a plurality of pieces of plank stuff mutually welded into a whole and is characterized in that the margin of a first plank stuff is provided with a flanging along the edge, the margin of a second plank stuff adjacent to the first plank stuff is provided with a groove with a concave section along the edge, and the flanging on the first plank stuff extends to the groove on the second plank stuff, and the first plank stuff and the second plank stuff are lap-welded together. The novel automotive body can effectively ensure the size accuracy of welding lines, improve integral strength of the automotive body, solve the problems of difficult integral punch forming of the outer surface of automotive body, such as a roof panel, caused by no large-size sheet material, punch equipment, etc. and difficult size control caused by common welding methods after sheet-metal and partition.
Description
Technical field
The utility model relates to the automotive body structure field, specifically is exactly automobile body external panel, as cap structure.
Background technology
At present domestic automobile body external panel is all-in-one-piece as major parts such as top covers, but because of the bigger outer surface structure of some sizes is subjected to the restriction of board dimension, can't whole punch forming, so need the piecemeal design; What some partitioned organizations adopted simultaneously is butt joint, some blocks of sheet materials are welded in the mode of butt welding be connected as a single entity, top cover body 1 and body 2 weld at solder joint 3 places after its edge part is drawn folding among Fig. 1, though this welding manner has avoided influencing because of solder joint the quality of outer surface, but the commissure be difficult for to guarantee dimensional accuracy, wait through welding and cause the distortion equal error to bring difficulty for the postorder assembly process, and the bulk strength after the welding a little less than, when driving, easy to crack when vehicle body twists distortion.
The utility model content
The purpose of this utility model just provides a kind of new automobile vehicle body that improves structure, can effectively guarantee to weld the dimensional accuracy of meeting the place and the bulk strength that improves body of a motor car.
A kind of new automobile vehicle body, it comprises some blocks of sheet materials that are welded to each other to one, it is characterized in that: there is the flanging that is provided with along the length of side in the edge of first sheet material, it is the groove of spill that the second sheet edge place adjacent with this first sheet material has along the cross section of length of side setting, and groove place and both joint welding that the flanging on described first sheet material stretches to second sheet material are one.
After adopting technique scheme, promptly adopt the Type of Welding of overlap joint, this Type of Welding guarantees the dimensional accuracy of commissure easily, and welding back bulk strength height.The utility model has overcome the vehicle body outside surface that reasons such as present domestic no large scale plate and pressing equipment cause, the uppity problem of size that welding manner causes as after top cover is difficult to whole stamping forming problem and panel beating piecemeal.

The specific embodiment
Shown in Fig. 2～7, body of a motor car comprises some blocks of sheet materials that are welded to each other to one, there is the flanging 11 that is provided with along the length of side in the edge of first sheet material 10, referring to Fig. 3, it is the groove 21 of spill that second sheet material 20 edges adjacent with this first sheet material 10 have along the cross section of length of side setting, see Fig. 5, groove 21 places and both joint welding that the flanging 11 on described first sheet material 10 stretches to second sheet material 20 are one, referring to Fig. 6,7.
Height between the plate face of top to the first sheet material 10 of described flanging 11 less than and near the degree of depth of the groove 21 on second sheet material 20, as shown in Figure 7, when guaranteeing weld strength, be convenient to the controlling dimension precision like this.
In conjunction with Fig. 5,7, the flanging 11 that the outside of described groove 21 is provided with on wide edge 22, the first sheet materials 10 is fitted with interior plate face and edge 12, is convenient to the controlling dimension precision when can guarantee weld strength like this.
The outer surface of first and second sheet material 10,20 forms neat roof outward appearance on same level and smooth surface.
The bar seam place that described flanging 11 cooperates with groove 21 is provided with glue envelope 30, on the groove of two top cover lap-joints, coats fine and closely woven glue envelope 30, with presentation quality that guarantees top cover and the effect of vehicle body being played sealing.In conjunction with Fig. 7, with the position of definite gluing and the bond pad locations of width and welding, shown in Fig. 6,7, beat solder joint 40 in the welding of the junction of two top covers, this kind overlapping mode can carry out self-adjusting because of the dimensional discrepancy of stamping parts at directions X to the top cover body, directions X is defined as the length direction of vehicle, has overcome the problem that the X that causes because of dimensional discrepancy is difficult to guarantee to quality of fit like this.
Be laid with concavo-convex muscle portion 12,23 on the outer surface of described first and second sheet material 10,20, the concave and convex direction of the muscle portion 12,23 on first and second sheet material 10,20 of lap-joint is consistent and be the gap-like cooperation each other.
Muscle portion 12,23 gap each other on described first and second sheet material 10,20 greater than, equal 2mm, for general medium sized vehicle, this gap is slightly larger than and gets final product near 2mm.
Shown in Fig. 8,9,10, at the Y of two top cover solder joints on section, promptly vertical and directions X, every muscle portion of top cover body in Fig. 9 12,23,13,24 places, position of the mo(u)lding line of side leave the panel beating gap that is not less than 2mm, the problem that the Z that causes with the dimensional discrepancy that overcomes because of two top cover body stamping parts can't guarantee to quality of fit to (vertical) and Y.
