Abstract

The present invention relates to a B-pillar assembly of a vehicle body that mitigates the impact during side impact of the vehicle body to protect the safety of passengers, and to reinforce the fragile structure by the plate reinforcement. To this end, the B-pillar of the present invention includes a pillar reinforcing agent interposed between the inner pillar member 3 and the outer pillar member 4 and includes a high rigidity impact beam 6, and the upper and lower ends of the impact beam. It is welded to the inner pillar member by the bracket (7), the filler 8 is inserted into the contact surface with the outer pillar member is made of a line contact structure.

Description

B-pillar assembly of the car body

The present invention relates to a B-pillar (B-pillar or center pillar) of an automobile body, and more particularly to a B-pillar assembly having a high rigidity effect on side impact.

The side structure of the car body is located between the rear door glass and the rear pinned shield glass and forms the rear side structure, and the C-pillar or the rear pillar, and the B-pillar is located between the rear door glass and the front door glass. Or a central pillar and an A-pillar or front pillar positioned between the front door glass and the wand shield glass to form a front side structure.

1 and 2 show a B-pillar assembly of a conventionally known differential vehicle body.

The B-pillar 1 is installed between the front door and the rear door of the differential vehicle body 2 and is configured by placing a pillar reinforcement 5 between the inner pillar member 3 and the outer pillar member 4. .

The inner pillar member 3 and the outer pillar member 4 are joined by welding both side flanges. The pillar reinforcement 5 is welded to the inner pillar member 3 and fixed by inserting a filler into the contact surface with the outer pillar member 4.

This B-pillar 1 absorbs the impact during side impact of the vehicle while supporting the roof and the door.

The conventional B-rela having the above-described structure, even when the inner pillar member and the outer pillar member are welded to each other, is partially contacted and formed into almost a space. There is this.

In addition, a pillar reinforcing agent provided between the inner pillar member and the outer pillar member has a weak plate shape and is shocked.

This problem is a structure in which a large amount of bending deformation of the vehicle body occurs in a side collision, it is unable to protect the safety of the passengers.

In order to solve the problems of the prior art, the present invention provides a differential vehicle body having a high rigidity reinforcement structure, which can prevent bending deformation caused by buckling caused by a collision impact during side impact of the vehicle. Provided is a B-pillar assembly.

As a means for realizing the above object, in the present invention, a pillar reinforcing agent interposed between the inner pillar member and the outer pillar member is composed of a high rigidity impact beam, and the upper and lower ends of the impact beam are inner with brackets. A B-pillar structure is welded to a pillar member and a filler is inserted into a contact surface with an outer pillar member to be in line contact.

According to this configuration, the B-pillar according to the present invention improves the rigid structure by the impact beam, it is possible to effectively prevent bending deformation due to buckling during side impact of the vehicle.

EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment for implementing this invention is demonstrated in detail based on an accompanying drawing.

EXAMPLE

3 is a B-pillar of the automobile body according to the present embodiment, and is a perspective view showing the internal structure, and FIG. 4 is a cross-sectional view of the B-pillar of the automobile body according to the present embodiment.

In describing the present embodiment, the same reference numerals are used for the configuration of the present embodiment, which is the same as the drawings cited in the prior art, and will not be described again for clarity.

Reference numeral 10 in the drawings refers to the entire B-pillar.

As described in the prior art, the B-pillar 10 constituting the side structure of the vehicle body is composed of an inner pillar member 3 and an outer pillar member 4 to which both pulleys are joined by welding, and the amount The pillar reinforcement is inserted between the members.

Here, the B-pillar 10 according to the present embodiment is characterized by being configured by reinforcing the structure of the pillar reinforcing agent.

More specifically, the pillar reinforcement of the present embodiment includes an impact beam 6 formed in a rod shape to have a high rigidity structure against side impact. The impact beam 6 is fixed by welding by placing a bracket 7 on the inner side and the lower end of the inner pillar member 3.

In addition, the impact beam 6 is in contact with the inner surface of the outer pillar member 4 by interposing an unspecified number of fillers 8.

According to the configuration of this embodiment described above, the pillar reinforcing agent has a high rigidity structure by the shape of the impact beam 6 having a rod-like structure, unlike the conventional plate-like structure.

Accordingly, the B-pillar 6 of the present embodiment mitigates the side impact impact of the vehicle by the impact beam 6, thereby preventing bending deformation due to buckling and effectively protecting the safety of the passenger.

Through the embodiments described above, it can be seen that the B-pillar assembly of the vehicle body according to the present invention solves the problems of the prior art.

That is, according to the present invention, the impact force is transmitted to the front surface of the vehicle body by the rod-shaped impact beam during the side collision of the vehicle, thereby obtaining an effect of preventing bending deformation.

This effect ultimately ensures the safety of the passengers.

On the other hand, the present invention is not limited to the above-described specific preferred embodiment, and any person having ordinary skill in the art to which the invention belongs without departing from the gist of the invention claimed in the claims, various modifications Would be possible.

Claims (1)
