Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a front combination lamp for use in motor vehicles, particularly cab-over type trucks.

Generally, while a car is running, mud, dust, etc. adhere to the front side of the car, making it dirty.
A press-formed recess is formed from the front panel to the side panel, and molded sheet metal is attached to the front panel to form an air duct corresponding to the recess.
Creates airflow along the panel and its sides.
I've been avoiding getting the panels dirty.

However, its front panel and side
The press structure of panels has become more complex, and the appearance finish has been affected.

In addition, it is desirable for the body of a car to have a structure that reduces air resistance as much as possible during driving, and in recent years, such structures have been introduced, especially in cars such as cab-over trucks, which have relatively large air resistance when driving. Various measures have been taken to reduce air resistance.

In other words, in this type of cab-over type truck, there is a tendency for an air rectifier to be installed above the cab to reduce the air resistance experienced by the loading platform. It is attached to the front corner panel and is designed to reduce air resistance at the front corner of the cab and improve fuel consumption.

In particular, the air baffle plate attached to the front corner panel has two types: one with a single structure and one with a built-in lamp. As a result, the installation work of these accessory parts becomes complicated, and in the latter case, there is a limit to the amount that the accessory parts can protrude from the side of the cab.
The distance from the side of the cab was narrowed by the lamp, making it difficult to obtain the necessary air flow rate.

The purpose of this invention is to widen the distance from the side of the car body without being restricted by the lamp, increase the amount of air flowing along the side of the car body, and prevent mud, dust, etc. from adhering to the side of the car body on the front side. This prevents dirt, dust, etc. from getting muddy on the side of the car body, and simplifies the work of attaching the various accessory parts to the car body on the front side without increasing the number of parts that can be attached to the car body. ,
Another object of the present invention is to provide a front combination lamp for use in automobiles that reduces air resistance at the front corners of the vehicle body when the vehicle is running.

With these issues in mind, the front combination lamp used in this invention was developed.
A combination lamp box that is attached to the front corner of a car and configured to be able to incorporate clearance lamps, front turn signal lamps, etc.;
On the front side of the vehicle, at least one side of the combination lamp box in the vertical direction is located at an appropriate distance from the front corner of the vehicle to create a rectified air flow layer along the side of the vehicle body. It is extended to an appropriate length, and the extended end includes an air baffle plate having a bent portion directed toward the front corner portion.

Hereinafter, preferred specific examples of the front combination lamp used in an automobile according to this invention will be described with reference to the drawings.

1 and 2 show a specific example 10 of a front combination lamp used in an automobile of this invention applied to a cab-over type truck 15. FIG.

The front combination lamp 10
a combination lamp box 11 mounted on each front corner portion 17 of the cab-over type truck 15 and configured to incorporate a clearance lamp 12 and a front turn signal lamp 13; An air baffle plate 14 is formed integrally with the combination lamp box 11 at an appropriate distance from the front corner portion 17 of the cab-over type truck 15.
It is composed of.

That is, the combination lamp box 11 is made of synthetic resin and is constructed so that a clearance lamp 12 and a front turn signal lamp 13 can be incorporated therein.

Of course, the combination lamp box 11 is the same as the cab-over type truck 15.
It is attached so that it slightly protrudes outward from the front corner portion 17 of the vehicle, and its shape can be arbitrary, depending on the design of the vehicle body, especially the shape of the front corner portion 17, and the air flow during driving. It is desirable that the structure be configured to have low resistance.

Furthermore, an air baffle plate 14 is integrally formed at one end, that is, at the outer end of the combination lamp box 11 configured in this manner.

The air baffle plate 14 is integrally molded from the same synthetic resin as the combination lamp box 11, and has an appropriate length in the vertical direction of the combination lamp box 11. Furthermore, each of the extended ends is integrally formed with a bent portion facing the front corner portion 17.

In this way, the combination lamp box 1 in which the air baffle plate 14 is integrally formed.
1 is located at each front corner portion 17 of the cab-over type truck 15,
It is fixed with screws.

Therefore, the air baffle plate 14 is located at an appropriate distance from the front corner portion 17 of the combination lamp box 1.
Accordingly, the distance between the side surface of the vehicle body at the front corner portion 17 and the air baffle plate 14 becomes wider, and the front corner of the truck 15 - The air turbulence at the corner portion 17 is rectified by the air rectifying plate 14, and the air flowing along the side of the vehicle body, that is, the side of the cab, is rectified, and a large amount of air flows along the side of the cab. In this way, a rectified air flow layer is formed, which prevents mud, dust, etc. from adhering to the cab side surface, and prevents dirt, dust, etc. from staining the cab side surface.

Of course, when installed in the front corner section 17 in this way, the clearance lamp 12 and the front turn
Wiring connected to each lamp bulb (not shown) of the signal lamp 13 connects to a clearance lamp switch (not shown) and a turn signal switch installed in the cab of the cab-over type truck 15. (not shown), respectively.

Next, in the front combination lamp 10 used in an automobile according to this invention,
The function of the air baffle plate 14 will be explained.

As described above, when the cab-over type truck 15 to which the front combination lamp 10 is attached runs, air from the front near the front corner portion 17 is diverted by the air rectifying plate 14. It is rectified and flows backward along the side of the cab, that is, the outer surface of the door.

Therefore, generation of turbulent flow near the front corner portion 17 is prevented, air resistance during running is reduced, and fuel consumption rate is improved.

Of course, since the air straightening plate 14 is integrated with the combination lamp box 11, there is no need to separately attach the combination lamp box and the air straightening plate to the cab as in the conventional case. Installation work is simplified,
Furthermore, since the space at the front corner portion can be used effectively, the appearance of the cab-over type truck 15 is less likely to be degraded.

According to this idea of Nyojo, the combination
A lamp box is attached to the front corner of the automobile and is configured to be able to incorporate clearance lamps, front turn signal lamps, etc., and an air baffle plate is installed along the side of the vehicle body on the front side of the automobile. Extending from the combination lamp box to a suitable length in at least one of the vertical directions from the combination lamp box at a suitable distance from the front corner portion of the vehicle so as to create a rectified air flow layer, and Since the elongated tip has a bent portion directed toward its front corner, compared to the case where an air duct is used,
Because of the air duct, openings and recesses to be pressed into the front panel and side panels are omitted, simplifying the pressing structure of the front panel and side panels, and making the pressing process easier. In addition, compared to the case of using a separately manufactured air baffle plate, there is no need to increase the number of various accessory parts that are attached to the front corner of the car body, and the installation of those accessory parts is easier. It simplifies the work and also
Compared to those with a built-in lamp structure, the front
The distance between the side of the car body and the air rectifying plate at the corner becomes wider without being restricted by the lamp, and when the car is running, the air flowing along the side of the car body is rectified on the front side of the car. A large amount of air flow is obtained, in other words, it is rectified along the side of the car body, and an air flow layer with a large flow rate is obtained, and mud, dust, etc. attached to the side of the car body are removed from the air flow layer. This prevents mud, dust, etc. from contaminating the sides of the vehicle body, and also reduces air resistance at the front corners.
