Abstract
The utility model provides a front column strengthening structure of a automobile, which comprises a side outer plate, a lower front column strengthening plate and a threshold strengthening plate assembly. The lower front column strengthening plate is welded on the inner side of a front column part on the side outer plate, the threshold strengthening plate assembly is welded on the inner side of the threshold part below the front column part on the side outer plate and is lap-welded with the lower end of the lower front column strengthening plate form a whole, the inner side of the lower front column strengthening plate is welded with a lower front column hinge strengthening plate in a position corresponding to a lower front door hinge, the lower front column hinge strengthening plate extends downwards to cover the lower part of the lower front column strengthening plate, and the lower front column hinge strengthening plate is provided with a nut hole. The utility model can not only satisfy the requirements for installation strength of the front door hinge to prevent the front door from falling off, but also can obviously enhance the joint strength of the front column and the threshold of the automobile body, meet the requirements for collision safety of the automobile body, improve the welding efficiency, and save the cost of tooling development.
Description
Technical field
The utility model relates to the auto body technical field, is specifically related to the A-pillar structure of automobile.
Background technology
The A-pillar of auto body need design additional strengthening, 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.When design, not only to consider 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 the automobile A-pillar additional strengthening is an independent hinge stiffening plate, the installation site of door hinge before being positioned at, and a brace panel is arranged in addition at A-pillar and threshold node place, booster action is played in the A-pillar bottom.Such structure welding process complexity, the integrated cost height, but also can not satisfy the collision safety requirement.
At present, the cost pressure of baby car is very big, and is more and more higher to the security requirement of body construction, in the accident that takes place, the probability of collision is very big, 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.The utility model structure design can effectively solve this type of problem.
Summary of the invention
The utility model is at the deficiencies in the prior art, proposes a kind of simple and practical, automobile A-pillar brace panel structure that safety is good.
The technical solution of the utility model is as follows:
A kind of automobile A-pillar structure, it includes side-wall outer-plate, A-pillar lower reinforcing plate and threshold brace panel assembly, described A-pillar lower reinforcing plate is welded on the inboard at the A-pillar position of side-wall outer-plate, described threshold brace panel assembly is welded on the inboard at the threshold position under the A-pillar position of side-wall outer-plate, and is welded as a whole with the lower end overlap joint of A-pillar lower reinforcing plate;
It is characterized in that: be welded with hinge stiffening plate under the A-pillar in the inboard corresponding position that hinge under the Qianmen is installed of described A-pillar lower reinforcing plate, hinge stiffening plate extends the whole A-pillar lower reinforcing plate of covering bottom downwards under the described A-pillar; On the hinge stiffening plate nut bore is arranged under the described A-pillar.
Newly-designed A-pillar additional strengthening is combined into a brace panel with hinge stiffening plate under the A-pillar and two parts of A-pillar bottom brace panel, carries out assembly welding with the A-pillar lower reinforcing plate, and then welds with other parts of gusset.This structure welding and assembling technics is simple, has reduced the frock development cost, has saved cost, the production efficiency height.Two smallclothes synthesize a bigger part simultaneously; also strengthened the intensity of A-pillar and threshold node; the intensity height; reasonable transmitted load; not only guaranteed the installation strength requirement of preceding door hinge; prevented to fall under the Qianmen, and improved the car body safety performance, make collision energy can more effective transmission, more effective protection occupant safety.
Description of drawings
Fig. 1 is an assembling scheme drawing of the present utility model;
Fig. 2 is the scheme drawing after the utility model assembles;
Fig. 3 is the structural representation of hinge stiffening plate under the A-pillar of the present utility model.
The specific embodiment
Referring to Fig. 1 and Fig. 2, this automobile A-pillar additional strengthening includes hinge stiffening plate 7 under side-wall outer-plate 9, A-pillar lower reinforcing plate 8, threshold brace panel assembly 6 and the A-pillar.Wherein A-pillar lower reinforcing plate 8 is welded on the inboard at the A-pillar position of side-wall outer-plate 9, and threshold brace panel assembly 6 is welded on the inboard at the threshold position under the A-pillar position of side-wall outer-plate 9, and is welded as a whole with the lower end overlap joint of A-pillar lower reinforcing plate 8.Hinge stiffening plate 7 is welded on the 8 inboard corresponding position welding that hinge under the Qianmen is installed of A-pillar lower reinforcing plate under the A-pillar, and hinge stiffening plate 7 extends the bottom that covers whole A-pillar lower reinforcing plate 8 downwards under the A-pillar.
The concrete structure of hinge stiffening plate 7 is referring to Fig. 3 under the A-pillar, the corresponding thereon position with the preceding door hinge of installation is provided with the first installation nut bore 2 and second nut bore 3 is installed, the angle of differing thereon is provided with main knock hole 1, its underpart is provided with auxiliary positioning hole 5 for one jiao, and the application leakage deflation hole 4 of a strip shape can be arranged at the bottom therein.
During welding: with hinge stiffening plate under the A-pillar 7 and A-pillar lower reinforcing plate 8 assembly weldings, weld together with gusset parts such as threshold brace panel assembly 6, side-wall outer-plates 9 more earlier.
Claims (2)
1. automobile A-pillar additional strengthening, it includes side-wall outer-plate, A-pillar lower reinforcing plate and threshold brace panel assembly, described A-pillar lower reinforcing plate is welded on the inboard at the A-pillar position of side-wall outer-plate, described threshold brace panel assembly is welded on the inboard at the threshold position under the A-pillar position of side-wall outer-plate, and is welded as a whole with the lower end overlap joint of A-pillar lower reinforcing plate;
It is characterized in that: be welded with hinge stiffening plate under the A-pillar in the inboard corresponding position that hinge under the Qianmen is installed of described A-pillar lower reinforcing plate, hinge stiffening plate extends the whole A-pillar lower reinforcing plate of covering bottom downwards under the described A-pillar; On the hinge stiffening plate nut bore is arranged under the described A-pillar.
2. automobile A-pillar additional strengthening according to claim 1 is characterized in that being provided with knock hole and application leakage deflation hole on hinge stiffening plate under the described A-pillar.
