Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pillar structure for an automobile in which a hollow portion of the pillar communicates with the outside of the vehicle and the air cleaner side.

(Prior art) For example, the pillar structure of a conventional automobile is as follows.
A structure as described in Japanese Utility Model Publication No. 59-4816 is known.

In this conventional structure, a shielding plate having small holes bored therein was provided in the hollow portion of the pillar above the ventilation port in the pillar outer and the communication port in the pillar inner.

The small holes have functions such as draining air and paint during panel painting (electrodeposition coating), draining water to prevent rust from the panel, and ventilating the inner space from moisture.

(Problems to be Solved by the Invention) However, in such a conventional automobile pillar structure, the shielding plate is formed to have the same size as the cross-sectional area of the pillar hollow part, and the small hole is not formed. Due to the perforations, there were problems listed below.

(b) The size of the shielding plate is large, which increases the weight considerably.

(b) The intake sound of the air cleaner leaks through the small hole, and the sound shielding is not sufficient.

(c) When draining water from an air conditioner or sliding roof installed on the roof using the pillar space, if the drain hose is stopped above the shielding plate, the water will fall onto the shielding plate and cause rust. occurs.

In addition, if the drain hose is to extend below the shield plate, a hole must be made in the shield plate and the drain hose must be passed through the hole, but the shield plate is provided on the closed section of the pillar. for,
That work is extremely difficult.

(Means for Solving the Problems) Therefore, in order to solve the above-mentioned conventional problems, in the present invention, a hollow pillar is formed in the vehicle body by a pillar outer and a pillar inner, and the hollow part of the pillar is With the ventilation port opened in the pillar inner and the air cleaner communication port opened in the pillar inner,
An insertion port is opened in the inner pillar that communicates with the outside of the vehicle and the air cleaner side and is above the ventilation port and the air cleaner communication port, and a storage case is provided on the insertion port side in the open section of the pillar where the insertion port is opened. A shielding plate having a notch formed therein is inscribed in the pillar and installed in a substantially horizontal state, and a storage case for a seatbelt retractor is inserted into the pillar from the insertion opening, and The means is attached to the pillar inner so as to abut the hollow part of the pillar and shield the hollow part of the pillar.

(Function) Therefore, in the automobile pillar structure of the present invention, the hollow portion of the pillar is closed with a shielding plate and a storage case, thereby insulating the intake noise of the air cleaner.

Further, even after the pillar outer and the pillar inner are joined together, work around the shielding plate can be performed through the insertion opening of the pillar inner.

In addition, by installing the storage case (completely closing the hollow part) after the painting process, the removal of air and paint during painting can be ensured through cutouts, etc. No need to make holes.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.
In explaining the embodiment, a case where the present invention is applied to a cab-over type automobile will be taken as an example.

First, the structure of the first embodiment shown in FIGS. 1 to 4 will be explained.

As shown in FIG. 1, the pillar structure of an automobile according to the first embodiment of the present invention has a pillar 10, a shielding plate 20, and a storage case 30 as its main components.

As shown in FIG. 2, the pillar 10 is arranged between the passenger door 101 and the rear door 102, and forms a frame structure to maintain the strength of the vehicle body.
The pillar outer 11 and the pillar inner 12 form a columnar shape having a hollow part 13 inside, and the upper end is joined to the roof 103.

A vent hole 14 is opened in the lower part of the pillar outer 11, and a grille 141 is fitted into the vent hole 14.

The pillar inner 12 is formed of an inner upper 121 and an inner lower 122, and both are joined together with the floor panel 104. Further, an insertion port 15 into which the storage case 30 is inserted is opened near the floor panel 104 of the inner upper 121, and an air cleaner communication port 16 is opened in the inner lower 122 at a position lower than the ventilation port 14. Inside the vehicle of this air cleaner communication port 16 is a storage box 4 that stores the air cleaner 40.
1 is provided, and this storage box 41 is communicated with the outside of the vehicle via an air cleaner communication port 16, a duct 17, and a ventilation port 14.

Incidentally, reference numeral 42 in the figure is an intake port of the air cleaner 40, which is provided at a higher position than the air cleaner communication port 16.

The shielding plate 20 closes the hollow part 13 of the pillar 10 with the storage case 30 and closes the air cleaner 40.
The purpose of this shielding plate 20 is to prevent the intake noise from being transmitted to the passenger compartment 105 side through the hollow part 13.
It is an iron plate shaped to abut on the inner surface of the pillar outer 11 without a gap, and is welded to the pillar outer 11 at a bent part 21, and a notch 22 for the storage case 30 is formed on the pillar inner 12 side.

The storage case 30, as shown in FIG.
0, and is brought into contact with the notch 22 through the sponge 31 so as to shield the hollow part 13 of the pillar 10, and the upper and lower center parts are bolted together with the seat belt retractor 50. It is tightened and fixed to the pillar inner 12.

A cover 32 is provided on the compartment 105 side of the storage case 30, and the seatbelt 51 is drawn out from an outlet 33 of the cover 32 toward the compartment 105.

Next, the operation of the embodiment will be explained.

First, the assembly procedure will be explained.

When assembling the vehicle body, insert the insertion slot 1 in advance.
A shielding plate 2 is attached to the pillar outer 11 at a position opposite to the pillar outer 5.
0 is welded and fixed, and then the pillar outer 11 and the pillar inner 12 are joined.

Once the car body is assembled, it is immersed in a paint bath and then electro-deposited. During this soaking in the paint tank, the air inside the hollow part 13 of the pillar 10 is removed by the shielding plate 2.
0 through the notch 22 upwardly. Also, when lifting the paint from the paint tank, the hollow part 1 of the pillar 10 is
The paint that has entered the interior of the housing 3 flows down from the notch 22.

When the painting is finished, a sponge 31 is applied to the notch 22 of the shielding plate 20, and the storage case 30 is pushed through the insertion port 15 to come into contact with the notch 22 through the sponge 31, thereby shielding the hollow part 13.

Then, the storage case 30 is fixed to the pillar inner 12 together with the seat belt retractor 50 by bolting, and further, the storage case 30 is fixed to the vehicle interior 1 of the storage case 30.
Attach the cover 32 to the 05 side.

Further, below the pillar 10, a duct 17 is passed from the vent 14 to the air cleaner communication port 16, and a grill 141 is attached to the vent 14.

As described above, the assembly of the pillar portion of the example structure is completed.

In this manner, the pillar structure of the first embodiment has an excellent sound insulation effect because the hollow portion 13 of the pillar 10 is completely covered by the storage case 30 and the shielding plate 20.

In addition, since the notch 22 is formed in the shielding plate 20, the shielding plate 20 can be made smaller and lighter. Moreover, during painting, air and paint escape through the notch 22, so the shielding plate 20 can be made smaller and lighter. Since there is no need to provide holes in the board 20, the sound insulation effect is enhanced.

Furthermore, since the sponge 31 is provided between the shielding plate 20 and the storage case 30, there is no possibility that the two 20, 31 will rub against each other and generate noise while the car is running.

In addition, the ventilation port 14 and the air cleaner communication port 16
Since these are communicated through the duct 17, the suction sound of the air cleaner 40 is difficult to be transmitted to the hollow portion 13 side of the pillar 10.

Furthermore, since the air cleaner 40 is provided within the storage box 41 and the air cleaner suction port 42 is provided above the air cleaner communication port 16, water is unlikely to enter the air cleaner 40.

Next, a second embodiment shown in FIG. 5 will be described.

In describing the second embodiment, structures similar to those of the first embodiment will be given the same reference numerals as those of the first embodiment, and explanations thereof will be omitted, and functions similar to those of the first embodiment will also be explained. omitted.

This second embodiment is an example in which a drain hose cutout 223 is formed in the shielding plate 220 in addition to a storage case cutout 222 .

Therefore, when assembling, insert the insertion port 1 after painting.
5, insert the drain hose 106 piped from above into the drain hose notch 223,
Connect the sponge 31 to the notch 222 and the drain hose 1.
06, then attach the storage case 30.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. included.

For example, in the embodiment, the shielding plate is attached to the pillar outer, but it may be attached to the storage case.

In this case, the sponge is provided between the shielding plate and the pillar outer.

Further, in the second embodiment, the drain hose is passed through the shielding plate, but other items such as a harness may be passed through the shielding plate.

Further, in the embodiment, a duct is provided between the ventilation port and the air cleaner communication port, but the duct does not necessarily need to be provided, and in addition, the air cleaner intake port may be opened in the pillar hollow portion.

(Effects of the Invention) As explained above, in the automobile pillar structure of the present invention, since the hollow part is closed by the shielding plate and the storage case, the shielding plate can be made smaller by the notch, and it is lightweight. This has the effect of making it possible to reduce costs and reduce costs.

Since there is no need to provide holes in the shielding plate for removing paint, etc., there is no leakage of sound and the sound insulation effect is enhanced.

Furthermore, work around the shielding plate, such as passing a drain hose through the shielding plate, can be performed using the insertion opening even after the pillar outer and pillar inner are joined, resulting in extremely improved work efficiency. .
