Abstract
The utility model relates to a front upright column reinforcing structure, which comprises a front upright column reinforcing plate, a front door upper hinge reinforcing plate, a front door lower hinge reinforcing plate and a front upright column support plate, wherein the front door upper and lower hinge reinforcing plates are welded at upper and lower hinge mounting positions on the inner side of the front upright column reinforcing plate respectively; the front upright column support plate is welded on the middle part of the inner side of the front upright column reinforcing plate; and the lower end of the front upright column support plate is lapped on the inner side of the upper end of the front door lower hinge reinforcing plate. Due to the adoption of the front upright column reinforcing structure, the requirement of the installation strength of a front door hinge can be met, and a front door is prevented from falling off; meanwhile, the strength of a front upright column and a threshold node of a vehicle body are enhanced remarkably, so that the requirement of collision safety of the vehicle body is met; and moreover, a structural welding technic is simple, so that the tool developing cost is reduced, and the cost is saved.
Description
Technical field
The utility model relates to the auto Body Technology field, is specifically related to a kind of front column strengthening structure.
Background technology
The A-pillar of auto body need to design the reinforcement structure, and to strengthen whole column position, the design of hinges brace panel is with the installation of door hinge before satisfying as design A-pillar brace panel.Not only to consider when design simultaneously and satisfy the needs of strengthening, also need to consider the comfort feature that is welded, to guarantee production efficiency.
In present technology, A-pillar hinge stiffening plate in front column strengthening structure of automobile is an independent hinge stiffening plate, be positioned at the installation site of front door hinge, and at A-pillar and threshold Nodes, a brace panel arranged separately, to the A-pillar bottom playing booster action.Such structure welding manufacturability is complicated, and integrated cost is high, but also can not satisfy the collision safety requirement.
At present, the cost pressure of baby car is very large, and is more and more higher to the security requirement of body construction, in the accident that occurs, the probability of collision is very large, and the rate of causing injury is very high, this just requires car body that better safeguard construction design is arranged when collision, and cost reduces again as far as possible simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of front column strengthening structure, can guarantee the installation strength requirement of front door hinge, prevent from falling under the Qianmen, simultaneously car body A-pillar and threshold node strength there is obvious humidification, satisfy the requirement of vehicle body collision safety, and the structure welding and assembling technics is simple, can reduce the frock development cost, saves cost.
Front column strengthening structure described in the utility model, comprise hinge stiffening plate and A-pillar stay bearing plate under A-pillar brace panel, Qianmen upper hinge brace panel, Qianmen, the upper and lower hinge stiffening plate in described Qianmen is welded on respectively the upper and lower hinge installation position of A-pillar brace panel inboard, described A-pillar stay bearing plate is welded on the middle part of A-pillar brace panel inboard, and A-pillar stay bearing plate lower end is overlapped on the inboard of hinge stiffening plate upper end under the Qianmen.
Under described Qianmen, hinge stiffening plate, A-pillar stay bearing plate are corresponding with the shape in A-pillar brace panel corresponding region respectively, and under A-pillar stay bearing plate lower end, Qianmen, hinge stiffening plate upper end and A-pillar brace panel all take the shape of the letter U in this regional cross section, and size is changed from small to big successively.
The utlity model has following advantage: the upper and lower hinge stiffening plate in Qianmen and A-pillar stay bearing plate are carried out assembly welding with the A-pillar brace panel simultaneously, and then carry out welding with other parts of gusset.This structure welding and assembling technics is simple, has reduced the frock development cost, has saved cost, and production efficiency is high.Stay bearing plate and lower hinge stiffening plate are similar to and synthesize a larger part simultaneously, also strengthened the intensity of A-pillar, reasonable transmitted load, not only guaranteed the installation strength requirement of front door hinge, prevent from falling under the Qianmen, and improved the car body safety performance, make collision energy can more effectively transmit, guarantee occupant's safety.
Description of drawings
Fig. 1 is assembly drowing of the present utility model;
Fig. 2 is along the section-drawing of A-A line in Fig. 1;
Fig. 3 is exploded view of the present utility model;
Wherein, 1, the A-pillar brace panel, 2, Qianmen upper hinge brace panel, 3, the A-pillar stay bearing plate, 4, hinge stiffening plate under the Qianmen.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Extremely shown in Figure 3 referring to Fig. 1, this front column strengthening structure, comprise hinge stiffening plate 4 and A-pillar stay bearing plate 3 under A-pillar brace panel 1, Qianmen upper hinge brace panel 2, Qianmen, Qianmen upper hinge brace panel 2 is box-like, its four angles are respectively equipped with technical gaps, be convenient to moulding, Qianmen upper hinge brace panel 2 is welded on the upper hinge installation position of A-pillar brace panel 1 inboard.Under the Qianmen, hinge stiffening plate 4, A-pillar stay bearing plate 3 are corresponding with the shape in A-pillar brace panel 1 corresponding region respectively, and under the Qianmen, the left and right sides and the lower end of hinge stiffening plate 4 is respectively equipped with flange.Under the Qianmen, hinge stiffening plate 4 is welded on the lower hinge installation position of A-pillar brace panel 1 inboard, and A-pillar stay bearing plate 3 is welded on the middle part of A-pillar brace panel 1 inboard, and A-pillar stay bearing plate 3 lower ends are overlapped on the inboard of hinge stiffening plate 4 upper ends under the Qianmen.Under A-pillar stay bearing plate 3 lower ends, Qianmen, hinge stiffening plate 4 upper ends and A-pillar brace panel 1 all take the shape of the letter U in this regional cross section, and size is changed from small to big successively, so that upright post reinforcing plate 1 was the basis in the past, successively hinge stiffening plate under the Qianmen 4 and A-pillar stay bearing plate 3 are positioned in A-pillar brace panel 1.
During welding, first hinge stiffening plate 4 under Qianmen upper hinge brace panel 2, Qianmen and A-pillar stay bearing plate 3 are carried out assembly welding with A-pillar brace panel 1 simultaneously, then get final product with the side-wall outer-plate welding.
If in the less demanding situation of collision star, can cancel A-pillar stay bearing plate 3, and cancel structure and the welding level that A-pillar stay bearing plate 3 can not affect other parts.
