Description

[Detailed explanation of the idea] This invention relates to the cab of an automobile.

In general, the rear pillars in the cab of a car are arranged on the outside of the cab, and the outer rear pillar is placed at an appropriate distance from the outer rear pillar.
Consisting of an inner rear pillar placed inside the pillar, an air outlet is provided at an appropriate position on the outer rear pillar, and an air outlet is provided at an appropriate position on the inner rear pillar. Air inlets are being formed respectively.

In other words, by forming air exhaust ports and air intake ports in the outer and inner rear pillars, which are arranged at appropriate intervals, the outdoor side and the indoor side of the cab are connected. However, in addition to ventilating the interior of the cab, the cabin has been designed to reduce the pressure difference between the outside and the inside of the cab when the door is opened and closed.

However, in a car whose cab rear pillar is configured in this way, wind noise generated near the air outlet of the outer rear pillar is likely to be propagated into the cab while the car is running. The noise level inside the cab tends to increase, which may have a negative impact on the comfort of the occupants.

The purpose of this invention is to not only ventilate the inside of the cab, but also to reduce the pressure difference between the outside and the inside of the cab when the door is opened and closed, and also to reduce the pressure difference between the outside and the inside of the cab when the door is opened and closed. reduce noise levels and reduce indoor noise levels.
Our goal is to provide cabs for automobiles that improve comfort.

To this end, the cab of this invention has an outer rear pillar and an air duct that is formed by the outer rear pillar.
The outer rear pillar and the inner rear pillar are connected to each other so that the inner rear pillar arranged inside the outer rear pillar communicates with the outdoor side and the indoor side of the cab via the air duct. An air exhaust port and an air intake port are formed at appropriate positions on each rear pillar, and an air chamber is formed near the air intake port by covering the air intake port on the indoor side of the cab. and an intake port cover that is attached to the inner rear pillar and has an open lower portion.

Hereinafter, preferred specific examples of the cab of an automobile according to this invention will be explained with reference to the drawings.

Figures 1 to 3 show a specific example 10 of the cab of this invention applied to a small truck.

The cab 10 of the automobile is arranged inside the outer rear pillar 11 so that the outer rear pillar 11 cooperates with the outer rear pillar 11 to form an air duct 15. The outer rear pillar 11 and the inner rear pillar 12 are connected to each other as appropriate so that the inner rear pillar 12 communicates with the outdoor side and the indoor side of the cab via the air duct 15. The air outlet 13 and the air inlet 14 formed in the position, and the inner side of the air outlet 13 and the air inlet 14 formed in the position, and the inner The intake port cover 16 is attached to the rear pillar 12 and has an opening 17 formed in the lower part.

That is, the cab 10 of the automobile has a floor panel 20 and a back window in the upper part.
a back panel 21 in which a glass 27 is fitted;
It consists of a rear pillar 22, a roof lane 23, a roof panel 24, a door 25, etc. attached to both ends of the back panel 21, and the rear pillar 22 is attached to the outer rear pillar 11.
and an inner rear pillar 12 disposed inside the outer rear pillar 11 so as to cooperate with the outer rear pillar 11 to form an air duct 15 extending in the vertical direction. It is composed of

The outer rear pillar 11 is press-formed from a steel plate so as to have a length slightly shorter than the height of the cab 10 and extend in the vertical direction. Air outlet 1
3 is formed.

The inner rear pillar 12 is press-formed from a steel plate so that it has almost the same length as the outer rear pillar 11 and extends vertically. , a plurality of air intake ports 14 are formed.

The air intake port 14 is formed into a louver shape by cutting and raising the lower portion of the inner rear pillar 12 outward.

Of course, the outer rear pillar 11 mentioned above is
Narrowed down as shown in Figure 3, therefore,
If the inner rear pillar 12 is placed on both ends of the outer rear pillar 11 and welded in such a state, the outer rear pillar 11 and the inner rear pillar 12
An air duct 15 is formed between the two.

The outer and rear parts combined in this way
One ends of the pillar 11 and the inner rear pillar 12 are overlapped and welded to one end of the back panel 21, and the lower ends are welded to the floor panel 20.

Further, it goes without saying that a door 25 hinged to the front pillar (not shown) is arranged on the front side of the outer rear pillar 11 and the inner rear pillar 12. 25 is closed, the inner panel 35 of the door 25
The weather strip 33 attached to
It is configured to contact the outer rear pillar 11.

When the outer rear pillar 11 and the inner rear pillar 12 are assembled to the cab 10 as described above, the air duct 15, the air outlet 13, and the air intake port 1
4, the outdoor side and the indoor side of the cab 10 are connected.

Of course, the air outlet 13 of the outer rear pillar 11 is designed to prevent water, sand, dust, etc. from entering.
Additionally, a grill (not shown) is attached which has a decorative function to improve the appearance.

Further, on the indoor side of the cab 10, below the inner rear pillar 12, an intake port cover 16 is attached to cover the air intake port 14.

That is, the inlet cover 16 is made of synthetic resin so as to cover the air inlet 14 and form an air chamber 18 at a position on the indoor side of the air inlet 14. A plurality of openings 17 are formed below.

Further, approximately the center portion of the intake port cover 16 is connected to the webbing 2 of the seat belt 28, which will be described later.
9 is formed along the vertical direction.

The intake port cover 16 configured in this manner is arranged to cover the air intake port 14 and is fixed to the inner rear pillar 12 with screws.

Of course, a trim board 26 is attached to the inside of the inner rear pillar 12. As such, the inlet cover 16 is attached to the trim board 26.
Although it is integrally molded with the trim board 26, it can also be molded separately and screwed to the trim board 26 thereof.

Furthermore, in the inner rear pillar 12,
A seat belt 28 is attached.

That is, a retractor 30 is attached to the inner rear pillar 12 at a position below the intake port cover 16, and an anchor plate 31 is attached at a position above the inner rear pillar 12. is attached and webbing 2
One end side of 9 is wound into its retractor 30 and the other end is attached to its anchor plate 31. Of course, the webbing 29 has
The tongue plate 32 is passed through the webbing 29, which is thus stretched between the retractor 30 and the anchor plate 31. In the stored state, a part of the webbing 29 is inserted into the recess of the inlet cover 16 described above. It is configured so that it can be accommodated in 36.

Therefore, even if the suction port cover 16 is disposed between the retractor 30 and the anchor plate 31, the storage of the webbing 29 is not hindered, and a proper storage state is maintained.

The automobile cab 10 according to this invention is constructed as described above, but other than the above-mentioned constructions, the construction is similar to the cab of an existing small-sized truck, so a description of those constructions will be omitted.

Next, the function of the intake port cover 16 in the cab 10 of an automobile according to this invention will be explained.

First, when the small truck runs, wind noise is generated near the air outlet 13 of the outer rear pillar 11, and the wind noise is transmitted through the air duct 15 to the inner rear pillar 12. is propagated to the air intake port 14 side.

However, since the air intake port 14 is covered by the intake port cover 16 and an air chamber 18 is formed between the air intake port 14 and the air intake port 14, the wind noise is caused by the air chamber 18. It is attenuated within the cab 10, and its direct propagation to the indoor side of the cab 10 is avoided.

Therefore, the noise level caused by the wind noise inside the cab 10 is attenuated, and comfort is improved.

Furthermore, if a mat, carpet, etc. is placed on the upper surface of the floor panel 20 at a position below the inlet cover 16, the inlet cover 1
Wind propagated from the opening 17 of 6 to the indoor side,
The mats, carpets, etc. provide further attenuation and lower the noise level.

Of course, the outdoor side and the indoor side of the cab 10 are connected through the air duct 15, the air outlet 13, and the air intake port 14, so that the interior of the cab 10 is ventilated. When the door 25 is opened and closed, the pressure difference between the outdoor side and the indoor side of the cab 10 is reduced.

According to this device with the above structure, not only ventilation inside the cab but also the pressure difference between the outside and the inside of the cab when the door is opened and closed is reduced, and wind noise when driving is reduced. An automobile cab can be obtained in which less noise is propagated to the indoor side, the indoor noise level is reduced, and the comfort is improved.
