Abstract

A vehicular air cleaner may include: a body having an air inlet port; a cover coupled to a body and having an air outlet port; an element inserted into or drawn from the body and the cover through a access port formed in one side of the body and the cover; a positioning assembly rotatably coupled to a lower portion of the element and vertically moving the element by rotation; and an element cover coupled to the body and the cover to prevent the element from being separated from the access port, wherein the positioning assembly includes driving shafts each fitted with fixing brackets formed on a flange along a side direction of the element, and a driven shaft fitted with a fixing bracket formed on a flange along a front side of the element and having ends rotatably engaged with a pair of driving shafts.

First claim

What is claimed is:

1. An air cleaner for vehicles, the air cleaner comprising:
a body having an air inlet port formed in one side thereof to intake air;
a cover coupled to an upper portion of the body to form a filter chamber, the cover having an air outlet port formed in one side thereof;
an element inserted into or drawn from the filter chamber through an access port formed in the body and the cover;
a positioning assembly rotatably coupled to a lower portion of the element and configured for vertically moving the element according to rotation of the positioning assembly; and
an element cover coupled to the access port to enclose the element within the body and cover;
wherein the positioning assembly includes a plurality of driving shafts, each rotatably supported by respective fixing brackets formed on respective side flanges of the element extending in a side direction of the element, and a driven shaft supported by a fixing bracket formed on a front flange of the element and having opposing ends rotatably engaged with respective driving shafts,
wherein each driving shaft has:
a handle on one end of the each driving shaft to allow a user to grab the handle to rotate the each driving shaft;
a bevel gear installed at an opposing end of the each driving shaft; and
a plurality of eccentric cams installed on the driving shaft along a length direction of the driving shaft, and

wherein driven shaft has:
bevel gears installed at both end of the driving shaft and engaged with a corresponding bevel gear of the driving shafts; and
an eccentric cam installed on the driven shaft along a length direction of the driven shaft.

2. The air cleaner of claim 1 , wherein at least one of the plurality of eccentric cams includes a diameter wider than that of the shaft and a first side protruding in a first direction, the protruded first side including a right-angled stopper surface and a rounded lower surface.

3. The air cleaner of claim 2 , wherein at least one of the plurality of eccentric cams includes a second side opposed from said first side, and a rotation limit protrusion protruding from the second side.

4. The air cleaner of claim 1 , wherein the element cover includes:
a cover member having a plate shape to prevent the element inserted into the access port from being exposed to the outside; and
locking members protruding from opposing sides of the cover member in a side direction of the cover member and removably coupled to the access port formed in the body and the cover.

5. The air cleaner of claim 4 , wherein the locking members include:
a locking pin protruding from opposing sides of the cover member and having a constraint protrusion formed thereon having one end inserted into the access port to thereby be fitted with a constraint hole formed to penetrate through the side; and
a releasing pin having a releasing protrusion formed thereon having one end coupled to an outer side of the access port to thereby release a constraint of the locking pin having one end inserted into the constraint hole.

6. The air cleaner of claim 4 , wherein the element cover further includes a coupling limit member allowing the cover member to be selectively coupled to the body and the cover according to a rotation position of the positioning assembly.

7. The air cleaner of claim 4 , wherein the element cover further includes a supporting roller including a supporting bracket protruding from one surface of the cover member and rotatably installed in the supporting bracket to thereby support a lower portion of a flange of the element elevated by a rotation of the positioning assembly.
