Description
Technical field
The utility model relates to the technical fields of Automobile Design and manufacture, and more specifically, the utility model relates to one kind
Side wall front stiffener structure.
Background technique
Between side wall inner and outer plates, in order to meet collision performance and good rigidity, can all there be stiffening plate structure.Before side wall
The stiffening plate structure in portion has very big effect on vehicle body.In side wall front stiffener, each position of stiffening plate is wanted
Ask not quite identical, current way is typically all to be divided into several parts, and each part may use different material and material
It is thick.In the prior art, as shown in Figure 1, stiffening plate is broken generally into A column lower reinforcing plate 1, A column upper reinforcing plate 2, top before side wall
Beam stiffening plate 3, B column reinforcement plate 4, threshold rear stiffener 5, threshold front stiffener 6 after they pass through punch forming, then pass through
It crosses and is welded to form a front stiffener assembly.Above-mentioned front stiffener forms a front in the form of the welding of multiple parts
The quantity of stiffening plate assembly, mold is more, and cost is relatively high, and it is accumulative that certain tolerance is generated after welding.In the front of side wall,
It is mounted with the hinge of front/rear door, the important component such as limiter and lock, the accumulative of tolerance has a certain impact to the quality of vehicle body.
Utility model content
In order to solve above-mentioned technical problem in the prior art, the purpose of this utility model is to provide a kind of side wall fronts
Stiffening plate structure.
A kind of side wall front stiffener structure, it is characterised in that: including A column lower steel plate, A column upper steel plate, upper junction steel plate,
Side bar steel plate, B column steel plate, threshold rear portion steel plate, lower junction steel plate and threshold front steel plate；The left end of upper junction steel plate and A column
The left end laser assembly solder of the right end laser assembly solder of upper steel plate, the right end of upper junction steel plate and side bar steel plate, under upper junction steel plate
Splice with B column Steel plate laser at end；The left end of lower junction steel plate and the right end laser assembly solder of threshold front steel plate, lower junction steel plate
The left end laser assembly solder of right end and threshold rear portion steel plate, the upper end of lower junction steel plate and B column Steel plate laser are spliced；A column lower steel plate
Upper end and A column upper steel plate left end laser joint, the left end laser joint of the lower end of A column lower steel plate and threshold front steel plate.
Compared with prior art, the side wall front stiffener structure of the utility model has the advantages that
(1) using being integrally formed, seperated molding number of molds is significantly reduced, can reduce die cost；
(2) welding edge needed when part welding is avoided, the material for capableing of more reasonable selection each region is thick, can subtract
The weight of light car body；
(3) the intensity deficiency of solder joint and stress are concentrated when avoiding welding, so can be improved the antifatigue destruction of vehicle body
Ability；
(4) it can be avoided the accumulated tolerance generated when welding, can be improved the peace of the installation part before side wall in stiffening plate
Fill precision.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of side wall front stiffener structure in the prior art.
Fig. 2 is the schematic diagram of the side wall front stiffener structure of the utility model.
Fig. 3 is the finished figure of the side wall front stiffener structure of the utility model.
Specific embodiment
It is further elaborated below with reference to side wall front stiffener structure of the specific embodiment to the utility model, with
It is more complete, accurate and deep that help those skilled in the art conceives the utility model of the utility model, technical solution has
Understand.
Embodiment 1
As shown in Fig. 2, the side wall front stiffener structure of the present embodiment include A column lower steel plate 11, A column upper steel plate 12, on
Junction steel plate 13, side bar steel plate 14, B column steel plate 15, threshold rear portion steel plate 16, lower junction steel plate 17 and threshold front steel plate 18.
The left end of upper junction steel plate 13 and the right end laser assembly solder of A column upper steel plate 12, the right end and side bar steel plate 14 of upper junction steel plate 13
Left end laser assembly solder, the lower end of upper junction steel plate 13 and 15 laser joint of B column steel plate.The left end of lower junction steel plate 17 and threshold
The right end laser assembly solder of front steel plate 18, the right end of lower junction steel plate 17 and the left end laser assembly solder of threshold rear portion steel plate 16, under
The upper end of junction steel plate 17 and 15 laser joint of B column steel plate.The upper end of A column lower steel plate 11 and the left end laser of A column upper steel plate 12
Splicing, the lower end of A column lower steel plate 11 and the left end laser joint of threshold front steel plate 18.Pass through integrated punching shape after laser joint
Reinforce plate shape before side wall at final finished as shown in Figure 3.It is by one by stiffening plate before the molding side wall of this scheme
Body formed mode obtains, and parts more multiple than existing mode distinguish punch forming, and the quantity of mold can be greatly reduced,
It can reduce the cost of mold.Do not weld that there is no need to the welding edges and bridging arrangement of former part welding position, so can
Reduce car body weight.It avoids caused solder joint bonding strength deficiency and stress when welding to concentrate, improves the antifatigue of vehicle body
Damage capability.So each region can more reasonably can be thinned than stiffening plate before the side wall that is welded by more parts
Part material is thick, further decreases the weight of part.The integrated punching molding that the present embodiment uses, avoids the welding of part, keeps away
Exempt from welding bring part accumulated tolerance, can be improved the installation accuracy of the installation part in front side wall stiffening plate.
For the ordinary skill in the art, specific embodiment has only carried out exemplary retouch to the utility model
It states, it is clear that the utility model specific implementation is not subject to the restrictions described above, as long as using the method concept of the utility model
The improvement of the various unsubstantialities carried out with technical solution, or the not improved conception and technical scheme by the utility model are direct
Applied to other occasions, it both is within the protection scope of the present invention.
