Description

[Detailed Description of the Invention] The present invention relates to a rectifying device on the cab side of an automobile.

The purpose of the present invention is to prevent the side surfaces of the cab from being soiled by mud, snow, etc. thrown up by the wheels with a very small number of components, and to improve safety for pedestrians.

When driving in the rain on the cab of a freight vehicle, mud kicked up from the tires adheres to the side of the cab and stains it. Particularly in the case of doors equipped with a see-through window below a normal window to expand lateral visibility, this see-through window may become dirty, causing poor visibility and impairing its function as a see-through window. be.

Conventionally, as a means of preventing dirt on the side of the cab, air rectifying plates were installed protruding from both sides of the cab.
There is a model that allows air to flow along the side of the cab, which is generated when driving, but this requires a special separate part to be attached to the cab, and also because it protrudes to the side of the cab. This is not desirable in terms of safety for pedestrians, etc. There are other types of air rectification by changing the shape and structure of the parts attached to the front of the cab, but these have the problem of not only complicating the structure but also increasing costs.

The present invention provides a rectifier that solves these problems, and its feature is that it rectifies the flow by using bumpers, at least near both ends of which are made of a soft material such as rubber or synthetic resin. It is a structure that has been formed.

Embodiments of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, 1 is a cab, 2 is a fender, 3 is a side plate, 4 is a step, 5 is a door, 6 is a transparent window, 9 is a tire, and 10 is a bumper.

Here, the bumper 10 is a bumper body 11 formed of sheet metal and provided with corner protectors 12 made of an elastic material such as rubber or synthetic resin at both ends, or as shown in FIGS. 6 and 7. The present invention is applicable to any structure in which the entire bumper body 11a is formed of an outer shell of synthetic resin, the inside is filled with urethane foam 14, and the back surface is closed with a reinforcement 15.

Therefore, in the case of the bumper 10 having the former structure, the corner protectors 12 provided at both end portions of the bumper 10 are
The air rectifying member 13 is integrally formed with the cab 2 so as to protrude above the bumper 10 with a gap between them. It is integrally molded so as to protrude above the bumper 10 with a gap between it and the cab 2.

This straightening member 13 is shaped to straighten out some of the air that hits the front of the cab 1 as the vehicle is traveling so that it flows along the side of the cab 1. For example, as shown in Figures 4 and 6, it has a cross-sectional shape that is bent at intervals to follow the shapes of the two front corners of the cab 1, and is structured to rise from the upper surface of the bumper 10 to a required height that corresponds at least to the height position of the fender 2.

Since the present invention has the above-described structure, the rectifying member 13 rectifies the air so that it flows along the side surface of the cab 1 as the vehicle runs, thereby eliminating the negative pressure phenomenon on the side surface of the cab 1.

Generally, the reason why the mud rolled up by the tires 9 adheres to the side of the cab 1 is that the side of the cab 1 becomes under negative pressure while driving, and the mud rolled up by the tires 9 is sucked up and adheres to the cab body surface. It is something to do.

According to the present invention, the rectifying member 13 eliminates the negative pressure phenomenon and also serves to blow away mud and the like rolled up from the tires 9 to the outside, thereby preventing the side surface of the cab 1 from becoming soiled.

In addition, since the present invention is integrally formed on both ends of the bumper, there is no need to manufacture and install separate dedicated parts as in the past, and the bumper can be attached to the vehicle body. Since a rectifying mechanism is immediately installed, assembly work can be simplified and costs can be reduced. Furthermore, since the flow regulating member is made of the same material as the soft material such as rubber or synthetic resin at the corner portion of the bumper, it has the advantage of ensuring safety for pedestrians.
