Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology belongs to a technical field in which the interior of a vehicle is ventilated by the load generated on the back of a mud guard attached to the rear of a rear wheel of an automobile.

This invention relates to a mud guard in which a bracket for mounting the body is provided protruding from the rear surface of the guard main body which is formed into a plate shape from an elastic material such as rubber. This invention relates to a mud guard that has a ventilation hole that communicates with a ventilation hole provided at the bottom of a quarter panel or the like of the body and communicates with an exhaust hole or the like on the lower side of the bracket.

<Prior art> Generally, a so-called muzzle guard made of an elastic material such as rubber is attached to the rear of the rear wheel of an automobile, but the conventional muzzle guard simply protects against dirt and mud thrown out from the rear wheel. Its only function was to prevent gravel from reaching the rear of the vehicle.

However, it is known that when air hits the muzzle guard while the vehicle is running, negative pressure is generated at and around the rear surface.

<Problems that the invention attempts to solve> Therefore, although it has such a negative function, there is a problem in that it does not have a positive function.

The purpose of this invention was to solve the problem of automobile muzzle guards based on the above-mentioned conventional technology, and focused on the negative pressure generated at the rear of the muzzle guard. The purpose of this invention is to provide an excellent muzzle guard which is useful in the field of fluid technology application in the automobile industry by providing a communication hole for venting and providing a ventilation function.

<Means/effects for solving the problem> In accordance with the above-mentioned purpose, the structure of this invention, which summarizes the scope of the above-mentioned utility model registration claims, is that in order to solve the above-mentioned problem, a guard body is provided that protrudes from the rear surface of the guard body. The bracket is provided with a ventilation hole that faces and communicates with the ventilation hole provided at the bottom of the guard's quarter panel, etc., so that the air inside the vehicle is evacuated by the negative pressure generated at and around the rear of the guard while the car is running. This is a technical measure that actively extracts air from ventilation holes in panels, etc., to promote indoor ventilation.

<Example> Next, an example of this invention will be described below based on the drawings.

It should be noted that the same parts are designated by the same reference numerals throughout the drawings.

In the embodiment shown in FIG. 1, a mud guard 3, which forms the gist of this invention, is attached to a rear position of a rear wheel 2 of an automobile 1, hanging in a natural state.

In the embodiment shown in FIGS. 2 and 3, the mud guard 3 has a bracket 5 integrally formed in a protruding manner on the upper rear surface of a guard main body 4 formed into a plate shape from an elastic body such as rubber. Bolt holes 6a and 6b for attachment to the body are bored at the top of the main body 4 and on the upper surface of the bracket 5.

A space 7 is formed inside the bracket 5, and an upper ventilation hole 8a is formed on the upper side of the space 7, facing an air ventilation hole (not shown) in the vehicle interior provided at the lower part of a quarter panel of an automobile, and a lower air ventilation hole 8a is formed on the lower side of the space 7. The exhaust hole 8b is open.

When the car 1 is run with the mud guard 3 having the above-mentioned configuration attached to the rear of the rear wheel 2, the mud guard 3
Negative pressure is generated on the rear surface and its vicinity as described above, and air is sucked and communicated from the upper ventilation hole 8a of the body quarter panel and the bracket 5 to the lower exhaust hole 8b.

As a result, the air inside the vehicle is forcibly extracted to the rear of the mud guard 4 through a ventilation hole (not shown) in the body communicating with the passenger compartment, thereby promoting ventilation within the vehicle.

Next, the embodiments shown in FIGS. 4 and 5 show other embodiments, in which a space 7 in the bracket bored on the rear surface of the guard main body 4 has a body connected to the passenger compartment on the upper side, as in the above-mentioned embodiment. The upper ventilation hole 8c facing the ventilation hole provided at the lower part of the quarter panel etc. is opened,
Further, side exhaust holes 8d are opened on both sides, and small-sized drain holes 9, 9 are bored in the lateral portions of the bottom surface.

The negative pressure generated on the sides of the mudguard 3 sucks the air inside the vehicle through the upper exhaust hole 8c, and exhausts it laterally through the side exhaust holes 8d, 8d.

By providing the exhaust holes 8d, 8d on the sides in this way, mud or dust is prevented from entering the space 7 from the lower part of the bracket 5, that is, from entering the ventilation holes of the body.

Further, water accumulated in the air 7 can be discharged from a drain hole 9 formed in the lower surface of the bracket 5.

It goes without saying that the embodiments of this invention are not limited to the above-mentioned embodiments; for example, each ventilation hole can be formed by a large number of small holes to further prevent mud and dust from entering the space. You can do it like this.

<Effects of the invention> As described above, according to this invention, a ventilation hole is provided on the upper side of the body mounting bracket provided on the rear surface of the guard main body, and a ventilation hole is provided on the lower part of the quarter panel of the body that communicates with the shaft. By arranging it to face the mudguard, and by providing an exhaust hole below it, the negative pressure generated at the rear of the mudguard and its vicinity forces the air inside the vehicle. This has the effect of promoting ventilation within the vehicle.

Furthermore, since the mudguard is used as such ventilation equipment, the ventilation system can be obtained without providing any particular exhaust equipment, and the structure is simplified.
