Description

Pillar Parts Assembling Structure of Mid Swing Door in Express Bus}

The present invention relates to a pillar assembly structure of a mid swing door for a high-speed bus, and more particularly, by molding the door pillar into an aluminum extrudate, it is advantageous not only to adjust the gap and step difference between the door pillar and the mid swing door, but also to separate the inner side. A pillar assembly structure of a mid swing door for a highway bus that does not require trim.

In general, the high-speed bus is a vehicle manufactured for high-speed driving, unlike a general city bus, and the front swing door is rotatably installed at the front side.

Recently, vehicles with rotatable mid swing doors have been released.

Inside the side glass is a pillar to reinforce the strength of the vehicle, and a watertight weather strip is installed in the gap between the pillar and the swing door glass.

FIG. 1 is a front view showing a typical mid swing door for a high speed bus, and FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1 showing a pillar structure of a conventional mid swing door for a high speed bus.

As shown in Figs. 1 and 2, the front swing door 2a is rotatably installed at the front side of the highway bus 1, and the mid swing door 2b is rotatably installed at the middle.

The pillars 4 are fixed to the inside of the side window glass 3 in the longitudinal direction thereof, and the pillars 4 are press-molded to constitute the inner pillars 4a and the outer pillars 4b.

The trim 5 is fixed to the inner pillar 4a. In addition, an inner 6 and a weathertight weather strip 7 are attached between the mid swing door 2b and the pillar 4.

Reference numeral 8 shows a mid swing door glass.

However, in the pillar assembly structure of the conventional high speed bus mid swing door configured as described above, the pillar is press-molded and formed of an inner pillar and an outer pillar, and the trim is fixed to the inner pillar, thereby making the overall structure complicated and press-molding. The work is difficult because it must be processed

In addition, in the pillar assembly structure of the conventional high speed bus mid swing door, the workability is inferior because the assembly process of attaching the trim is performed separately.

In addition, in the pillar assembly structure of the conventional high speed bus mid swing door, since the pillar is press-molded, it is difficult to adjust the gap and the step of the tip of the pillar and the mid swing door, and the watertightness decreases.

The present invention has been proposed to solve the above problems, and by forming the door pillar into an aluminum extrudate, it is advantageous not only to adjust the gap and step difference between the door pillar and the mid swing door, but also does not require a separate trim on the inner side. Therefore, the object of the present invention is to provide a pillar assembly structure of a mid swing door for a high-speed bus that can reduce cost, protect aesthetics, and enhance watertightness.

※ Explanation of symbols about main part of drawing ※

1: Express Bus

2a: Front Swing Door

2b: Mid Swing Door

3: Side Glass

4: Pillar

8: Mid Swing Door Glass

110: extruding material for pillar cover

111: Bolt

In order to achieve the above object, the present invention, the pillar is fixed in the longitudinal direction of the inside of the side window glass, the pillar cover extruding on one side of the pillar to cover the gap between the pillar and the mid swing door It is fixedly installed.

The pillar cover extrudate is made of aluminum, and the pillar cover extrudate is bolted to the pillar.

Hereinafter, with reference to the accompanying drawings will be described a characteristic configuration of the present invention.

FIG. 1 is a front view showing a typical mid swing door for a high speed bus, and FIG. 3 is a pillar cover assembly structure of the mid swing door for a high speed bus of the present invention.

As shown in FIG. 1, the front swing door 2a is rotatably installed at the front side of the express bus 1, and the mid swing door 2b is rotatably installed at the middle.

As shown in FIG. 3, in the pillar cover assembly structure of the mid swing door for the high speed bus of the present invention, the pillar 4 is fixed in the longitudinal direction to the inside of the side window glass 3, and the pillar 4 is fixed. The pillar cover extrudate 110 is fixedly installed on one side of the pillar 4 in order to cover the gap between the middle swing door and the middle swing door 2b. The pillar cover extrudates 110 are fastened to the pillars 4 by bolts 111.

The pillar cover extrudate 110 is preferably formed of aluminum material to realize a light weight. Reference numeral 8 shows a mid swing door glass.

In the pillar part assembly structure of the conventional high speed bus mid swing door, as shown in FIG. 2, the pillar is press-molded and consists of an inner pillar and an outer pillar, and a trim is fixed to the inner pillar, and press forming process is performed. There was a difficulty in the assembly work such as going through and attaching the trim separately.

In order to solve this problem, in the pillar portion assembly structure of the high speed bus mid swing door of the present invention, the pillar cover extrudate 110 is fastened to one side of the pillar 4 by bolts 111 and the weather strip 6, 7) It is not only fixed but also trimmed.

Therefore, the present invention does not require a press molding process in forming the pillar, and the pillar cover extrudate 110 itself serves as a trim, and thus has a structure in which a trim does not need to be attached.

In addition, in the pillar part assembly structure of the high speed bus mid swing door of the present invention, it is not necessary to press-form the pillar, thereby simplifying the work process, and the gap between the pillar cover extrudate 110 and the mid swing door 2b. And it is possible to easily adjust the step to protect the beauty and improve the watertightness.

As described above, the present invention is advantageous in controlling gaps and steps between the door pillars and the mid swing doors by molding the door pillars into an extruded aluminum, which facilitates work, improves the appearance, and improves the watertightness.

In addition, since the present invention does not require a separate trim on the inner side, cost can be reduced.

In addition, since the present invention does not go through the press forming process of the pillar, the workability can be improved by reducing the process.
