Description

[Detailed description of the invention] This invention blows air from the front of the cab out to the side of the cab through a duct between the floor side plate outer and inner plate provided on the step plate at the bottom of the side of the cab. The present invention relates to a cab-over type automobile that prevents splash, etc. that enter through a gap from adhering to the side surface of the cab.

As shown in FIG. 1, a step plate 2 is provided at the lower end of the side surface of a cab 1 of a cab-over type automobile to facilitate the entry and exit of a passenger. That is, as shown in FIG.
is provided on the lower end side of the floor side plate outer 3, and its front side is supported by the lower end side of the front pillar 4, and its rear side is supported by the front end side of the tire fender 5. Floor side plate outer 3 is
It is installed astride the front pillar 4 and tire fender 5, and is connected to the end side of the cab floor panel 6. Also, on the floor side panel outer 3,
Two protrusions 3a and 3b, bulging outward from the cab side surface, are formed on the upper side of the step plate 2. These first and second
The protrusions 3a and 3b are formed to reinforce the floor side plate outer 3. The first protrusion 3 a is in contact with a door sealing material 8 bonded to the inner surface of the lower end of the side door 7 . Also the second
The protrusion 3b of the cab 1 is larger than the first protrusion 3a.
is formed below the door seal material 8 and does not come into contact with the door seal material 8.
It does not engage with any other member.

On the inner side of the floor side plate outer 3,
The floor side plate inner 9 is installed and the first
The openings of the protrusion 3a and the second protrusion 3b are closed to form a first duct 10a and a second duct 10b.

These first and second ducts 10a and 1
0b increases the member rigidity of the floor side plate outer 3. That is, these ducts 10a and 10b have a box structure with the first and second protrusions 3a and 3b and the floor side plate inner 9 that closes the open side of these ducts, so that the floor side plate outer 3 This is intended to reduce the stress generated in the member.

Since the step plate 2 requires a gap 2a to prevent freezing, snow accumulation, and mud accumulation, it is formed in a drainboard shape, a round hole shape, a lattice shape, or the like. Therefore, the splash from the tire 11 passes through the gap 2a of the step plate 2, as shown by arrow A, and springs up onto the upper side of the cab 1. On the other hand, the air that collided with the front of Cab 1,
As shown by arrow B in Fig. 1, it once swells to the side and then flows out to the rear along the side of the cab. Therefore, the above-mentioned swelling area becomes a vacuum, and the splash of muddy water etc. that has come up is sucked out.
Attach it to the side of the cab. As a result, the door glass 12, the see-through window 12a, the door outer handle 13, etc. of the side door 7 become dirty, which reduces visibility and is dangerous, as well as making it inconvenient to open and close the side door 7. In order to overcome this drawback, various means have been adopted to direct the airflow along the side surface of the cab, but no simple and effective method has been found.

The present invention solves the above-mentioned drawbacks, and its purpose is to prevent splash from tires from adhering to the side of the cab, and to provide a simple and inexpensive cab-over type vehicle that does not require the attachment of special parts. Our goal is to provide the following.

An air intake port communicating between the front side of the cab and the duct is formed at a position opposite to the at least one protrusion on the floor side plate inner, and at the at least one protrusion on the floor side plate outer, At the rear of the air intake port, an air outlet is formed which faces the open port of the air intake port, communicates with the outer side of the cab, and has an open port that opens toward the front side of the cab. A portion of the air colliding with the front of the cab is taken into the duct, and then blown out from the outlet to the rear of the cab, sweeping away the splash that has come up from the step plate to the rear.
This car features a cab-over type vehicle that prevents dirt on the side of the cab.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In FIGS. 3 to 5, the same reference numerals as in FIGS. 1 and 2 indicate the same parts or the same functions.

An air intake port 14 is formed by cutting and raising a part of the floor side plate inner 9 at a position opposite to the second protrusion 3b on the cab front side of the floor side plate inner 9. This air intake port 14 forms an open port 14a on the front side of the cab. Moreover, the opening 14a communicates with the inside of the second duct 10b.

Further, in the second protrusion 3b, a plurality of air outlets 15, which are partially cut and raised inward, are arranged in parallel in the front-rear direction.

The air outlet 15 is formed on the rear side of the air intake port 14 and is provided at a position facing the air intake port 14 . Moreover, the open port 15 of the air outlet 15
A is open to the front side of the cab and communicates with the outer side of the side surface of the cab.

Therefore, the air entering the second duct 10b from the open port 14a of the air intake port 14 flows through the air outlet 15.
It passes through the opening 15a and flows out to the outside of the cab.

Note that since the first protrusion 3a comes into contact with the door sealing material 8 bonded to the inner surface of the lower end of the side door 7, the air outlet 15 is not formed in the first protrusion 3a, and therefore the first duct 10a does not apply to air passages.

Next, the operation of the embodiment will be explained.

As shown in FIG. 3, the splash from the tire 11 springs upward from the gap 2a of the step plate 2 as described above. On the other hand, a part of the air that collided with the front side of the cab 1 flows into the second duct 10b from the air intake port 14 as shown by arrow C, is accelerated, and is suddenly blown out from the air outlet 15 toward the rear side of the cab. be done. As a result, the splashing splash is swept away toward the rear of the cab as shown by arrow D. Furthermore, as described above, since the second protrusion 3b is provided on the lower side of the cab 1, the splash is swept away from the lower side of the cab 1 toward the rear of the cab. Therefore, splash is prevented from adhering to the door glass 12, see-through window 12a, door outer handle 13, etc. of the side door 7.

On the other hand, the air intake port 14 and the air outlet 15 are formed by cutting and raising a part of the floor side plate inner 9 and the floor side plate outer 3a, and do not require the installation of any special members, making it simple and inexpensive. It can be manufactured.

In the above embodiment, the air intake port 14 is shown at one location, but of course the air intake port 14 is not limited to this. Further, although there are a plurality of blow-off ports 15, the present invention is not limited to this, and the blow-off ports 15 may be formed in a plurality of rows. In addition, the air intake port 14 and the air outlet 1
5 is not limited to that formed by cutting and raising.

Further, the present invention is not limited to the second duct 10b, and a plurality of ducts may be formed between the first protrusion 3a and the step plate 2.

As is clear from the above description, according to the present invention, it is possible to prevent splash from tires from adhering to the side surface of the cab, and it is also simple and inexpensive.
