Abstract

PURPOSE: A vehicle air filter is provided to simply mount a filter into a blower unit without separating a glove box from a vehicle. CONSTITUTION: A vehicle air filter includes first and second frames(A,B), and a compression filter(6) inserted between the first and second frames. The first and second frames are coupled with each other by a spring(4) not to be separated from each other during operation. The spring serves to expand the filter after the air filter is mounted to a blower unit. The first and second frames are coupled each other at both ends. A holding part lever(9) has a holding part(9a) coupled with a first indent groove(3a), and a holding part(10) of a main lever(5) is coupled with a second indent groove(7a), so that the compression filter is in the compression state. As the holing part lever is released from the holding part of the main lever by pulling a knob(2) of the main lever outwardly, the first and second frames are separated from each other by the elasticity of the spring and the compression filter.

Description

Air filter for vehicle

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle air filter, and more particularly, to a vehicle air filter that can be easily mounted without removing the glove box from the vehicle in order to mount the filter inside the blower unit.

A blower unit is used to adjust the air temperature inside the vehicle. Since the blower unit sucks air from the outside, it contains dust or foreign matter, and thus, an air filter is used to remove the foreign matter. Air filters are parts that must be replaced frequently, which vary from vehicle to vehicle, but must be replaced every 15,000 km or every year. When the air filter was not replaced, there was a problem that the air volume drastically decreased and the performance also decreased when the heater and the air conditioner were operated.

The air filter replacement method of the conventional vehicle is briefly described as follows.

After preparing a screwdriver, spanner, etc., open the glove box and remove the glove box stopper on the side of the lower crash pad. The water glove box is then lowered completely by pulling the damper strap through the hole. Loosen the glove box fixing bolts and screws to remove the glove box. Remove the lower crash pad by loosening the screw and nut on the lower crash pad side. Disconnect the luggage compartment lamp connector. Remove the undercover from the blower by sliding the cover towards the floor. Remove the filter cover. Replace the air filter. The assembly is carried out in the reverse order of disassembly.

However, in order to replace the air filter in the conventional vehicle, it takes about 30 minutes or more because it requires a complicated disassembly and coupling operation as described above, but it is one factor of avoiding the service in the maintenance shop due to the low service charge. In addition, from the driver's point of view, there was a problem such as being a cause of dissatisfaction because the cost of a simple air filter replacement.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide an air filter for a vehicle that can be easily mounted without removing the glove box from the vehicle in order to mount the filter inside the blower unit. .

In the air filter for a vehicle of the present invention for achieving the above object, a locking jaw and a handle knob are formed at the upper end of the lever, and a locking jaw lever having a locking jaw formed at the upper end is formed in the opposite position spaced a predetermined distance from and adjacent thereto. An outer guide is formed and a first frame is formed between the locking jaw lever and the outer guide to a first fixing projection for fixing one end of the spring, and for fixing the spring in the vertically opposite position of the first fixing projection 2 fixing protrusions are formed and a first groove for fixing the locking jaw adjacent to the second fixing protrusion is formed, and a second groove is formed in a horizontally opposite position spaced apart from the first groove. A second frame having an inner guide installed therein and comprising a locking jaw release lever protruding from both ends connecting the first and second grooves; Characterized in that it consists of a compression filter inserted between two frames.

Hereinafter, a vehicle air filter of the present invention will be described in detail with reference to the accompanying drawings.

1 is a plan sectional view of a vehicle air filter of the present invention. As shown, the compression filter 6 is located at the center, and is fixed in a form in which the first frame A and the second frame B are enclosed around the compression filter 6. The compression filter 6 has a shape compressed about half as compared with the conventional one. In such a compressed state, when mounted on the blower unit, it is expanded to have the same size as the conventional filter.

The first frame A and the second frame B surrounding the compression filter 6 are separated from each other, and the first frame A and the second frame B are springs 4 so as not to separate during use. ) Is connected. The spring 4 also serves to allow the filter 6 to expand after mounting the air filter of the invention to the blower unit.

In addition, the first frame (A) and the second frame (B) are coupled at both ends. In the drawing, the locking jaw (9a) of the locking jaw lever (9) is coupled with the first groove (3a), the lever on the right side The locking jaw 10 formed at (5) is coupled to the second recess 7a. By the fixed state as described above, the compression filter 6 maintains the compressed state.

On the other hand, the locking step release lever 3 is inserted in the second frame (B) and both ends protrude. One end is inserted into the locking jaw 10 and fixed, and the other end protrudes into the first recess 3a. An end protruding into the first recess 3a is in contact with the locking jaw 9a of the locking jaw lever 9.

2 shows an expanded state, that is, a state mounted on the blower unit, which is essentially expanded by the expansion force of the compression filter 6 itself and the elastic force of the spring 4. In order to expand the compression filter 6, when the user pulls the knob knob 2 outward, the locking jaw release lever 3 moves in a direction in which the locking jaw release lever 3, which is fixed by being caught by the locking jaw 10, is pulled out. The locking jaw lever 9 is released by the other end of (3).

When the locking jaw lever 9 is released, the compression filter 6 is expanded while the first frame A and the second frame B are separated by the elastic force of the spring 4 and the compression filter 6 itself. In particular, it is preferable that the lever 5 of the first frame A and the inner guide 7 of the second frame B exposed to the outside have a sufficient width and width to be used as a cover of the blower unit.

A detachable state of the vehicle air filter of the present invention as described above will be described with reference to FIGS. 3A-3C. In order to replace the filter, without removing the glove box 12 first, the vehicle air filter of the present invention filter the upper portion of the glove box 12 toward the lower crash pad 11 as shown in Figure 3a Insert into the insertion case (1). The inserted state is a state in which the compression filter 6 is compressed as shown in FIG.

After inserting the vehicle air filter as shown in the figure, the user pulls the knob knob 2 outward. As the handle knob 2 moves, the locking jaw release lever 3 connected thereto moves to the right, and the locking jaw lever 9 is released accordingly. When the state is released, the first frame A and the second frame B are separated by the spring 4.

Shown in Figure 3b is the vehicle air filter of the present invention in an expanded state. After mounting the vehicle air filter as described above, the user places and fixes the glove box 12 as shown in the drawing. As described above, the mounting of the vehicle air filter is completed.
