JPS6010202Y2 - Bypass device around the air cleaner intake section - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a device for temporarily introducing air into an air intake space of an air cleaner of an automobile.

A conventional air intake space of this type is schematically shown in FIG.

In the figure, 01 is an air cleaner, 02 is an intake part of the air cleaner 01, 03 is a floor panel, and 04 is an air cleaner cover, which is formed to protrude inward from the floor surface of the floor panel 03 to the sloped surface in front of the floor panel 03. 05 is a headlamp support, which forms an air intake space 06 between it and the air cleaner cover 04 by its plate surface.

The tip of the intake part 01 opens into the space 06.

When driving through the crossing ditch, there was a big swell of water, and the water surface was 07.
is above the lower surface of the floor panel 03, the space 06 is in a sealed state, and the air passage is choked.

In this state, the negative pressure of the engine is applied to the linear cleaner 01.
If the amount of air sucked into the space 06 is larger than the volume of the space 06, water may be sucked in and problems such as engine malfunction and seizure may occur.

Conventionally, the only way to increase the volume when the vehicle is choked is by attaching the aforementioned headlamp support or air cleaner cover, but if the volume is increased, it will protrude into the interior of the vehicle, impairing comfort, and there is a limit to how much this can be done.

The purpose of the present invention is to provide a device that can eliminate the above-mentioned drawbacks, and its features include an air cleaner cover that is disposed on the underside of the floor panel and projects upward from the floor panel, and a head on the front end of the vehicle body. In the air cleaner, the tip of the intake part is opened in the space formed by the lamp support and the lower part is open, and the same space is used as the air intake part. A pillar internal space and the air intake part, one end of which opens above the air intake part, and the other end of which is opened in the front pillar internal space and at a higher position than the one end; It consists of a bypass hose that communicates with the inlet.

Embodiments of the present invention will be described above with reference to the drawings.

FIG. 2 is an explanatory diagram showing the outline of an embodiment of the device according to the present invention, FIG. 3 is a sectional view taken along the line A-A in FIG. 2, and FIG.
FIG. 5 is a sectional view taken along the line BB in the figure, and FIG. 5 is a perspective view showing the apparatus shown in FIG. 2.

In the figure, 1 is the intake part of the air cleaner, 2 is the air cleaner body, 4 is the floor panel, 5 is the front pillar inner, 6 is the front pillar outer, 7 is the air cleaner cover, 8 is the front panel, 9 is the headlamp support, 10 is the The front cross member is the same as the conventional one.

Reference numeral 11 denotes a space that forms an air intake section that opens at the tip of the intake section 1 of the air cleaner.The upper surface is formed by the air cleaner cover 7, and from the front surface of the intake section 1 to both sides, there is a curved surface with the center portion protruding forward. It is surrounded by a headlamp support 9 forming a .

12 is a space formed inside the front pillar by the front pillar inner 5 and the front pillar outer 6.

Reference numeral 3 designates a bypass hose that communicates the upper part of the internal space 12 of the front pillar with the upper part of the air cleaner cover 7 forming an air intake section.

Note that the arrow α indicates the front.

The operation in the case of the above configuration will be described.

If the water level rises above the lower surface of the floor panel 4 while the vehicle is running and the air passage is choked, the air intake section 11 (7) and the air cleaner cover 7 are connected to the space 12 via the bypass hose 3.
More air is supplied.

Note that air is not supplied from this bypass hose 3 under normal operating conditions.

In the case of the present invention as described above, if the air passage to the air intake part of the air cleaner is choked, air is supplied from the bypass hose, so there is no problem with engine malfunctions, seizures, etc. that are seen in conventional systems. This has the effect of preventing problems.
