Description

Center pillar of car body

The present invention relates to a center pillar of a body for a passenger vehicle, and more particularly, to a center pillar of a body for a passenger vehicle forming a column such that a loop is coupled to a center body.

An automobile is composed of a body, which is the exterior of the automobile, and a chassis formed by installing an engine or equipment necessary for driving on the chassis frame. Particularly, the frame constituting the chassis includes the type, use, Depending on the driving method and the installation position of the suspension system, it is divided into the ordinary frame and the special frame, and the ordinary frame is divided into the H type frame and the X type frame.

In addition, a frame integrated structure in which the chassis is integrally formed with a body may be widely adopted for a passenger car. Such a frame integrated structure includes a central vehicle body 2 forming a center of a vehicle body as shown in FIG. The front body 4 and the rear body 6 extending in front and rear portions of the center body 2, in particular, the center body (2) is a filler assembly (10) and a floor panel assembly (12) and a roof panel It consists of the assembly 14.

In particular, the filler assembly 10 includes a pair of front pillars 20 disposed at the front of the vehicle, a pair of rear pillars 22 disposed at the rear, and a front door assembly 24 and a rear. A pair of center pillars 30 (also referred to as 'B' pillars) are disposed between the door assemblies 26.

As shown in FIG. 2, the pair of center pillars 30 includes an inner panel 32 disposed inside the vehicle interior, and an outer panel 34 welded to the inner panel 32 in a shape of a box. Consists of

In addition, the inner panel 32 and the outer panel 34 are in contact with the welded portion is formed by a flange 36, the predetermined bending portion of the water-tight portion of the weather strip (W) mounted to the door assembly (D) Close contact.

On the other hand, the door assembly, in particular the assembly (D) of the rear door mounted on the center pillar 30 is coupled to the center pillar 30 in a state that can be opened and closed by the door hinges (40, 42), The same door hinges 40 and 42 are each mounted to the door assembly D and the other to the outer panel 34 of the center pillar 30 and hinged to each other.

By the way, the center pillar of the conventional passenger vehicle body as described above has a problem that the part to which the door hinge is coupled is easily recessed by an external force, and is pushed into the cabin to injure the occupant.

The present invention has been made in order to solve the conventional problems as described above, the object of the present invention is to reinforce the outer panel of the door hinge is coupled to the easy depression by the external force, and the injury of the occupant due to the depression The present invention provides a center pillar of a passenger vehicle body that can be prevented in advance.

2 is a cross-sectional view taken along line II of FIG. 1 for illustrating a center pillar of a conventional vehicle body;

3 is a cross-sectional view taken along line II of FIG. 1 for illustrating a center pillar of a body for a passenger vehicle according to the present invention;

--- Explanation of symbols for the main parts of the drawing ---

24: front door assembly 26: rear door assembly

30: center filler 32: inner panel

34: outer panel 40, 42: door hinge

44: reinforcement

In order to achieve this, the present invention provides an outer panel coupled to a rear end portion of the front door assembly in a close state, the outer panel being hinged to open and close the rear door assembly, and an inner weld welded to the outer panel in the shape of a box. A center pillar of a body for a passenger vehicle composed of a panel, the center pillar of the body for a passenger vehicle, characterized in that the reinforcement is coupled to the outer side of the outer panel of the portion where the door hinge is coupled in an overlapping state.

Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings, the same reference numerals will be given to the same parts as in the prior art.

One embodiment of the present invention is composed of a central vehicle body 2 forming the center of the vehicle body as shown in Figure 1, the front vehicle body 4 and the rear vehicle body 6 extending in the front and rear portions of the central vehicle body 2, In particular, the above-described center vehicle 2 is related to a body for passenger vehicles composed of a pillar assembly 10 and a floor panel assembly 12 and a roof panel assembly 14.

In particular, the filler assembly 10 includes a pair of front pillars 20 disposed at the front of the vehicle, a pair of rear pillars 22 disposed at the rear, and a front door 24 and a rear door. It consists of a pair of center pillar 30 arrange | positioned in between.

As shown in FIG. 3, the pair of center pillars 30 includes an inner panel 32 disposed inside the vehicle interior, and an outer panel 34 welded to the inner panel 32 in a hollow shape. The inner panel 32 and the outer panel 34 are in contact with each other and are welded to each other, and are formed of a flange 36.

Meanwhile, the watertight portion of the weather strip W mounted on the door assembly D is in close contact with a predetermined bent portion of the outer panel 34 constituting the center pillar 30, and the door assembly, in particular, the center pillar 30 The assembly (D) of the rear door mounted on is coupled to the center pillar 30 in a state capable of being opened and closed by the door hinges 40 and 42.

The door hinges 40 and 42 are each mounted to the door assembly D and the other to the outer panel 34 of the center pillar 30 and hinged to each other, and the door hinges 42 is coupled to the outer panel 34 at the portion where the reinforcement 44 overlaps in a state where a plurality of closed sections on the cross section are formed.

The center pillar of the passenger vehicle body according to the present invention as described above has the advantage of being able to easily prevent depression due to external force and injury of the occupant due to the depression in advance.
