Abstract
The utility model reveals an assembly structure for strengthening the A-pillar of an automotive body, and the structure comprises a front-door upper hinge installing plate, a stopper installing plate, an A-pillar strengthening plate, a front-wheel-cover outer strengthening plate, and a side-wall outer plate. An-shaped side surface of the topper installing plate is welded on an outer flange at a side of the front-door upper hinge installing plate, thereby forming two bulged structures which bulge in the same direction, wherein the section of the outer flange is omega-shaped. Two omega-shaped side outer flanges of the front-door upper hinge installing plate are welded at an inner side of the A-pillar strengthening plate. The rear end of the front-wheel-cover outer strengthening plate and the side-wall outer plate are respectively welded with the outer surface of the A-pillar strengthening plate. The structure provided by the utility model can apparently strengthening the collision capability of the A-pillar, improves the safety performance of the automotive body, and effectively guarantees the safety of passengers. Meanwhile, the technologies of punching and welding are taken into full consideration. The structure is convenient for punching forming, reduces welding positions, saves cost, and improves the efficiency of production.

Technical field
The utility model relates to automotive body structure, relates in particular to a kind of auto body A post and strengthens assembly structure.
Background technology
Along with social development, user is more and more higher to the various requirement of automobile, and special safety performance has come first.In auto against, require vehicle body to possess very strong structure, good collision energy-absorbing effect, can bring higher safety performance, and especially, aspect passenger protection, vehicle body A post plays very important effect.Enough strong vehicle body A post, in auto against, can reduce the distortion of driving compartment, the intrusion of fireproof brickwork, guarantees that Qianmen is not extruded gross distortion, guarantees that car door normally opens.A post can also guarantee rigidity and the intensity of front door hinge attachment point simultaneously, prevents the sagging of Qianmen, guarantees the normal use at Qianmen.Therefore, only guarantee that vehicle body A post has enough intensity, possesses pipeline and the energy-absorbing effect of good power, guarantee occupant's safety during collision.
Guarantee the intensity of A post, if by increasing, panel beating material is thick, high-yield strength steel plate or overstriking A column section are realized, cost certainly will increase.Packing when the general welding manner of front wheel housing external reinforcing plate for car is main spelling, freezes and is connected with side wall assembly CO2, needs to increase the station that freezes, and increases cost.Vehicle body A-pillar structure design difficulty is to possess good safeguard construction and rational force path, minimizes cost simultaneously and simplifies welding process.
Utility model content
Technical problem to be solved in the utility model is that to realize a kind of welding process simple, cost of manufacture is low, can effectively strengthen A post intensity simultaneously, the pipeline of power while improving collision, impact loading forms the auto body A post assembly of good secondary extinction and strengthens structure.
To achieve these goals, the technical solution adopted in the utility model is: a kind of auto body A post assembly is strengthened structure, comprise Qianmen upper hinge adapter plate, limiting device adapter plate, A column reinforcement plate, front wheel housing external reinforcing plate for car and side-wall outer-plate, described limiting device adapter plate is N-shaped one side and is welded on the flange of described Qianmen upper hinge adapter plate one side that cross section is several fonts, and form two outstanding in the same way bulge-structures, several fonts both sides flanging welded of described Qianmen upper hinge adapter plate is in described A column reinforcement plate inner side, described front wheel housing external reinforcing plate for car rear end and side-wall outer-plate all weld with A column reinforcement plate lateral surface.
Described front wheel housing external reinforcing plate for car has the turnup structure extending to car inner side, and described turnup structure and Qianmen upper hinge adapter plate and limiting device are installed formed bulge-structure plate in the same horizontal line.
Described front wheel housing external reinforcing plate for car rear end is coated on A column reinforcement plate, and the end face that front wheel housing external reinforcing plate for car contacts with side-wall outer-plate welds mutually.
The end face that described front wheel housing external reinforcing plate for car contacts with side-wall outer-plate is coated with PVC glue.
The utility model A post is strengthened assembly structure can obviously strengthen A post collision ability, improves the safety performance of vehicle body, effectively protects occupant safety; take into full account punching press and welding process simultaneously, be convenient to drawing, reduce the station that freezes; cost-saving, enhance productivity.

The specific embodiment
Known referring to Fig. 1-6, auto body A post assembly is strengthened structure and is comprised Qianmen upper hinge adapter plate 1, limiting device adapter plate 2, A column reinforcement plate 3, front wheel housing external reinforcing plate for car 4 and side-wall outer-plate 5, wherein limiting device adapter plate 2 is N-shaped, Qianmen upper hinge adapter plate 1 is several fonts, on the flange of several fonts one side of N-shaped one welding Qianmen, the side upper hinge adapter plate 1 of limiting device adapter plate 2, form two outstanding in the same way bulge-structures, during collision, play good supporting role, reduce the deflection of A post, meet again hinge attachment point and limiting device attachment point rigidity and requirement of strength simultaneously, avoid door falling and limiting device to lose efficacy, also in the time of can avoiding front wheel housing external reinforcing plate for car 4 with side-wall outer- plate 5 and 3 welding of A column reinforcement plate, there are four layers of weldering.
Several fonts both sides flanging welded of Qianmen upper hinge adapter plate 1 is in A column reinforcement plate 3 inner sides, and front wheel housing external reinforcing plate for car 4 rear ends and side-wall outer-plate 5 all weld with A column reinforcement plate 3 lateral surfaces.Front wheel housing external reinforcing plate for car 4 is connected with 3 spot welding of A column reinforcement plate, avoids traditional CO2 connection of freezing, and reduces freeze equipment and station, reduces costs.Side-wall outer-plate 5 also adopts spot welding to be connected with A column reinforcement plate 3, optimizes structure simultaneously, avoids four layers to weld now, smears PVC glue 6 being prone to cavity position, improves air-tightness herein.
As shown in Figure 6, front wheel housing external reinforcing plate for car 4 cross sections are U-shaped, formation has the turnup structure extending to car inner side, this turnup structure and Qianmen upper hinge adapter plate 1 and limiting device adapter plate 2 are in the same horizontal line, the flange up and down and the Qianmen hinge mounting plate 1 that are front wheel housing external reinforcing plate for car 4 align in Z-direction with the box like structure that limiting device adapter plate 2 forms, the transmission of load while being conducive to collide.The pipeline of power when vehicle body A-pillar structure as shown in Figure 3 collides, impact load is mainly delivered to power on A column reinforcement plate 3, Qianmen upper hinge adapter plate 1 and limiting device adapter plate 2 by front wheel housing external reinforcing plate for car 4.
After the 4 rear ends welding of front wheel housing external reinforcing plate for car, be coated on A column reinforcement plate 3, and front wheel housing external reinforcing plate for car 4 welds mutually with the end face that side-wall outer-plate 5 contact, guarantee that connection is abundant.The end face contacting with side-wall outer-plate 5 at front wheel housing external reinforcing plate for car 4 is coated with PVC glue 6 simultaneously, to improve vehicle sealing property.
