Description
Technical field
The utility model relates to car side wall manufacturing technology field, and particularly a kind of car side wall of luggage-boot lid overlapping part bad order and moulding cracking on the gusset that prevents improves structure.
Background technology
Generally, the rear design of car side wall has the luggage-boot lid overlapping part, can hold an overlap joint on the gusset at this position and dodge breach, be the rigidity of luggage-boot lid overlapping part and the needs of assembling, product can design the additional strengthening of a flange moulding, because the shape facility at this position changes comparatively complicated, the punch forming difficulty is easy to generate the defective of bad order, has a strong impact on the attractive in appearance of motorcar body, reason is that this genius loci variation is too violent, draw the early stage contact point few, cause and walk to expect freely that the zone is too big, walk to expect unstability, the moulding later stage can not fully be extended and opened, and causes surface irregularity; Luggage-boot lid overlapping part, overlap joint dodge breach to dodge angle less, be generally less than 100 degree, the radius of dodging the angle fillet is below 50mm, the unstability zone is bigger, difficult forming, the flange moulding is expected more less, gusset ftractures easily.
Chinese patent notification number CN201347130Y, November 18 2009 day for announcing, announced a kind of body side wall, comprise side-wall outer-plate and roof drip, roof drip is welded on the side-wall outer-plate, and on roof drip, the inboard of roof drip and side-wall outer-plate lap-joint is provided with flange, damage side-wall outer-plate when flange being set preventing to weld, but the structure of luggage-boot lid overlapping part in patent and on the not mentioned gusset.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, a kind of improvement structure of car side wall is provided, it can prevent on the gusset that rough apparent defect appears in luggage-boot lid overlapping part outside face and the flange cracking appears in this position, has improved the structural strength and the aesthetics of luggage-boot lid overlapping part on the gusset.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of improvement structure of car side wall, comprise the gusset body, luggage-boot lid overlapping part on the described gusset body is provided with the overlap joint of flange moulding and dodges breach, overlap joint is dodged the open end of breach and the junction of gusset body edges forms the flex point of protruding, overlap joint is dodged the additional face of drawing work that breach flange shaping area is provided with projection, drawing work is replenished face and is dodged the two flex points formation gusseted of gap opened end with overlap joint, and drawing work is replenished and also is provided with the poly-material convex closure that prevents the flange cracking on the face.Luggage-boot lid can overlap with gusset, therefore on gusset, can be provided with specially to overlap and dodge breach so that luggage-boot lid and gusset overlap joint, it is to process by the flange forming process that overlap joint is dodged breach, it is V-shaped that overlap joint is dodged breach, the design drawing work is replenished face, and drawing work is replenished face and is dodged the two flex points formation gusseted of gap opened end with overlap joint, can reduce material flow instability like this, avoiding producing material can not fully extend, and causes the rough defective of luggage-boot lid overlapping part outside face; Drawing work is replenished face integral body and is crescent, drawing work is replenished increases a poly-material convex closure on the face, poly-material convex closure is the convex closure with tapering, poly-material convex closure upper surface is a cambered surface, poly-material convex closure is positioned at drawing work and replenishes on the face that to dodge the breach sealing near overlap joint distolateral, this can expect less to replenish to the technology of postorder flange moulding, and it is about the same to guarantee to draw the material of gathering and material that flange lacks, can effectively prevent the flange cracking phenomena.
As preferably, the angle of dodging that described overlap joint is dodged breach is 100 ° ~ 140 °, dodges preferred especially 120 ° of angle.Increase and dodge angle, be beneficial to the flange moulding, prevent to produce the defective of bad order, by practical test, to determine best angle.
As preferably, the angle of dodging that described overlap joint is dodged breach is a fillet, and described radius of rounding is 80 mm ~ 150mm, the preferred especially 100mm of radius of rounding.Dodging angle is fillet, avoids stress concentration, gains in strength, and the appropriate design radius of rounding is to reach best effect.
As preferably, the curved convex of described poly-material convex closure.The outside face of poly-material convex closure is cambered surface, and is more attractive in appearance.
As preferably, described poly-material convex closure hill height is 5mm ~ 10mm, the preferred especially 10mm of hill height.The poly-material of appropriate design convex closure hill height, suitable to guarantee to draw the material of gathering and material that flange lacks, can effectively prevent the flange cracking phenomena.
As preferably, the hill height that drawing work is replenished face is 10mm ~ 30mm, the preferred especially 20mm of hill height.The appropriate design drawing work is replenished the hill height of face, and to reduce material flow instability, avoiding producing material can not fully extend, and causes the rough defective of luggage-boot lid overlapping part outside face.
The beneficial effects of the utility model are: the design drawing work is replenished face, and drawing work is replenished face and is dodged the two flex points formation gusseted of gap opened end with overlap joint, can reduce material flow instability like this, avoiding producing material can not fully extend, and causes the rough defective of luggage-boot lid overlapping part outside face; Drawing work is replenished increases a poly-material convex closure on the face, poly-material convex closure is positioned at drawing work and replenishes on the face that to dodge the breach sealing near overlap joint distolateral, this can expect less to replenish to the technology of postorder flange moulding, assurance draw the material of gathering and material that flange lacks about the same, can effectively prevent the flange cracking phenomena.
