Description

[Detailed explanation of the idea] The present invention relates to a mud water intrusion prevention device for vehicles.

Referring to FIGS. 1, 3, and 4 showing conventional mud water intrusion prevention devices, 1 is a front fender panel of a vehicle body, 2 is a fender apron, 3 is a front side member, 4 is a bonnet, and 5 is an engine. 6 is an engine, 7 is a cold air intake pipe for guiding cold air into the engine room 5, and 8 is a front wheel.

On the outer wall surface of the fender apron 2 surrounding the front wheel 8, an inner end portion 10 of a synthetic resin fender liner 9 extending laterally and substantially horizontally is fixed by, for example, screws.

On the other hand, as shown in FIG. 4, in the upper part of the front wheel 8, the outer end of the fender liner 9 is fixed to the inwardly bent part 12 of the front fender panel, which is bent inwardly at the wheel arch part 11 of the front fender panel, by screws, for example. be done.

On the other hand, as shown in FIG. 3, in front of the front wheel, the outer end of the fender liner 9 is not fixed to the front fender panel 1, but is separated from the inner wall surface of the front fender panel 1 by a small distance. .

The reason why the 7ender liner 9 is not fixed to the front fender panel 1 in this way is because the front fender panel 1
This is because if the fender liner 9 fixing bolts are attached to the front 7 ender panel 1, the appearance of the front 7 ender panel 1 will be damaged.

Also, the reason why the outer end of the fender liner 9 is separated from the inner wall surface of the front fender panel 1 by a small distance is because the outer end of the fender liner 9 is in contact with the inner wall surface of the front fender panel 1. 7 The outer end of the ender liner 9 rubs against the inner wall surface of the front fender panel 1 due to vibration, and as a result, rust not only occurs on this friction surface, but also on the outer surface of the front fender panel 1 on the opposite side to this friction surface. This is because rust occurs.

However, if the outer end of the ender liner 9 is not fixed to the front fender panel 1 in this way and is separated from the inner wall surface of the front fender panel 1 by a small distance, muddy water will be thrown up by the front wheels 8 when driving in a muddy channel. Due to the collision force, the fender liner 9 is pushed upward as shown by the broken line in FIG. A large amount of muddy water enters the space 13 formed between the front fender panel 1 and the fender apron 2 through the gap.

In this way, not only the rust prevention function, which is the original purpose of the 7ender liner 9, is impaired, but also the muddy water infiltrates into the air cleaner through the cold air intake pipe 7, causing engine malfunction.

The present invention provides a muddy water intrusion prevention device that completely prevents muddy water from entering the space between the front fender panel and the fender apron while providing a gap between the outer edge of the fender liner and the inner wall surface of the front fender panel. It is about providing.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Fig. 2 shows the muddy water intrusion prevention device according to the present invention.

In FIG. 2, the same components as in FIG. 3 are indicated by the same reference numerals, and their explanations will be omitted.

Referring to FIG. 2, the inner end of a seven-ender liner 9 made of a synthetic resin material with high weather resistance and impact resistance is fixed onto the outer wall surface of the fender apron 2 with, for example, screws.

Above the front wheel 8, the outer end of the fender apron 2 is connected to a front fender panel inwardly bent portion 12 which is bent inwardly at the front wheel arch portion 11, as shown in FIG.
For example, it is fixed with screws.

On the other hand, as shown in FIG. 2, in front of the front wheel 8, the outer end 14 of the fender liner 9 is bent diagonally downward.

Further, a slight gap is provided between the outer edge 15 of this bent outer end portion 14 and the inner wall surface of the front 7 ender panel 1.

When muddy water is thrown up by the front wheels 8, the muddy water collides with the fender liner 9 and then flows toward the bent outer end 14 as shown by arrow A.

The flow direction of this muddy water is deflected downward along the bent outer end 14, but at the same time, the muddy water is deflected downward along the bent outer end 14.
, causing the bent outer end 14 to rotate clockwise about its bending point 16 as shown by arrow B.

As a result, the outer edge 15 of the bent outer end 14 is in sealing contact with the inner wall surface of the front fender panel 1, thus reducing the space 13 between the front fender panel 1 and the fender apron 2.
It can prevent muddy water from entering inside.

As described above, according to the present invention, it is possible to prevent muddy water from entering the space between the front fender panel and the fender apron.
It is possible to suppress the occurrence of rust on the outside wall of the construction apron,
Furthermore, since muddy water does not enter the air cleaner through the cold air intake pipe, it is possible to prevent engine malfunctions caused by muddy water.

Claims (1)

[Scope of utility model registration request] The inner end of a synthetic resin fender liner for preventing muddy water intrusion that extends almost horizontally on the outer wall surface of the lower part of the apron in front of the front wheels of the vehicle is fixed, and the outer end of the fender liner is attached to the inner wall surface of the front fender panel. In a muddy water intrusion prevention device that extends close to the fender liner and isolates the space formed between the fender apron and the front fender panel in front of the front wheels of the vehicle from the outside by the fender liner, the outer end of the fender liner is moved diagonally downward. A mud water intrusion prevention device for a vehicle, which is bent toward the front end and has a slight gap between the outer edge of the bent outer end and the inner wall surface of the front fender panel.
