Description

Automotive Center Filler Assembly

1 is a perspective view for explaining the application of the present invention,

2 is a cross-sectional view taken along the line A-A of FIG.

3 is a cross-sectional view of a conventional center pillar assembly taken along the A-A portion of FIG.

[Industrial use]

The present invention relates to a center pillar assembly for an automobile, and more particularly, to a center pillar assembly for an automobile for reducing stiffness by increasing rigidity during side impact of an automobile to promote rider safety.

Conventional technology

In an automobile, the center pillar assembly is disposed in a direction perpendicular to the vehicle at both middle portions of the vehicle body to support the roof panel assembly.

3 is a cross-sectional view showing a conventional center pillar assembly, and shows an out panel 51 and an inner panel 53.

The out panel 51 has a structure for forming a protrusion to the outside.

In addition, the inner panel 53 has a structure of forming a protruding portion inwardly, and has a structure of forming a hollow portion 55 by being flanged to the out panel 51.

As described above, the hollow part 55, which is a space formed by the inner panel 53 and the out panel 51, enables the intrusion of the out panel 51 to absorb the shock when an impact caused by a collision occurs at the side surface. will be.

[Problems to Be Solved by the Invention]

However, such a center pillar assembly structure for automobiles is composed of a structure in which only the outer panel and the inner panel are joined, so when a collision occurs at the side surface, the inner and out panels penetrate the inside of the vehicle and the passenger's safety is prevented. There is a problem that can not be planned.

[Means to solve the problem]

The present invention has been made to solve the problems of the prior art as described above, and an object of the present invention is to prevent the impact force of the side surface applied to the out panel, thereby reducing the intrusion amount of the vehicle body generated by this impact force. To provide a vehicle center pillar assembly structure to ensure the safety of.

In order to realize the above object of the present invention, the inner and the outer panel which is installed at regular intervals spaced apart in the vehicle width direction, and the side reinforcing member which is respectively interposed between the front end and the rear end of the junction of the inner panel and the out panel, Provided is a center pillar assembly for an automobile including a center reinforcing member interposed between the inner panel and the center of the outer panel.

[Action]

Since the reinforcing member is inserted into the hollow portion of the inner and out panels, the center pillar assembly structure for automobiles configured as described above increases the resistance due to side impact.

EXAMPLE

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail.

1 is a perspective view schematically showing a frame of a vehicle for explaining the application of the present invention, showing a roof panel assembly 1 and a center pillar assembly 3 supporting the roof panel assembly 1; have.

The center pillar assembly 3 is installed at both sides in a direction perpendicular to the vehicle body, which is configured to support the roof panel assembly 1 and the center follower panel assembly 5.

2 is a side cross-sectional view showing the center pillar panel assembly cut away, showing an out panel 7, an inner panel 9, and reinforcing means interposed between the out panel 7 and the inner panel 9. Doing.

And 11 center pillar trim.

The reinforcement means consists of a side reinforcement member 13 and a center reinforcement member 15.

The side reinforcement member 13 is interposed between both sides of the flange joint of the outer panel 7 and the inner panel 9 to form a structure that is also flange bonded.

The side reinforcement member 13 has a structure installed in a direction perpendicular to the out panel 7 and the inner panel 9, respectively.

And the side reinforcing member 13 is made of a structure that is projected slightly rounded to the center.

The structure of the side reinforcing member 13 as described above is to support the pressing force in various directions when a collision occurs in the outer side.

The center reinforcing members 15 are formed in pairs so as to be symmetrical at the center of the inner panel 9 and the out panel 7, and the inside of the center reinforcing member 15 forms a hollow portion 17 and is also perpendicular to each other. ) And a flange joint to the inner panel 9.

And the center reinforcing member 15 is shown by illustrating the structure in which the ends are flange-bonded to each other on the side of the panel 7 as shown in Figure 2, but is not limited to this, and directly flanged to the out panel It may have a structure to do.

And the flange reinforcement of the center reinforcing member 15 and the inner panel 9 side is shown, respectively, but this also shows the structure that is joined, this also the end of the center reinforcing member 15 is bonded and the outer peripheral surface of the inner panel (9) It can also be combined with

The center reinforcement member 15 has a structure in which an intermediate portion thereof protrudes toward the center side.

As described in the side reinforcing member 13, this is for effectively coping with stiffness during side impacts of various angles.

The reinforcement means has been described in the reinforcement member consisting of a pair in the side and the center, respectively, in the present invention, in particular in the center reinforcement member 15, it may be manufactured by installing one or three or more.

This is to reduce the manufacturing process and cost, or to maximize the effect of the reinforcing member.

The center pillar assembly for automobiles of the present invention thus formed has side reinforcing members 13 and center reinforcing members 15 which are vertically joined to the out panel 7 when a collision occurs on the side of the vehicle and an impact is applied thereto. It is possible to mitigate intrusion into the car with the support of.

[Effects of the Invention]

As described above, according to the present invention, the inner panel and the outer panel are joined to each other via reinforcing means, thereby reducing the intrusion amount of the vehicle body caused by the impact force, thereby achieving safety for the occupant.
