The present invention relates to an assembly structure of an air extractor grill for a vehicle, and more particularly, to an assembly apparatus of an air extractor grill which improves workability during assembly and facilitates removal.

In general, as shown in FIG. 1, the air extractor grill, which serves as a passage through which the indoor air of the vehicle is discharged to the outside, has an opening / closing valve 2 hingedly coupled to the grill housing 1. .

The air extractor grille is assembled by pushing the grille housing 1 through an assembly hole formed in the vehicle panel 5 so that the locking jaw 3 formed at the upper and lower ends of the grille housing 1 is provided with the sealing pad 4 interposed therebetween. The assembly is completed while hanging. The sealing pad 4 interposed between the vehicle body panel 5 and the grill housing 1 is compressed during assembly to block the penetration of moisture. Reference numeral 6 is a dust cover.

As described above, the assembly of the conventional air extractor grill is performed by the operator forcibly pushing the grill housing so that the locking jaw 3 of the grill housing is hung and fixed to the vehicle body panel 5 by the operator. ) And when the thickness of the sealing pad 4 interposed between the vehicle body panel 5 is too thick, an excessive force is applied to the grill housing 1 and the workability is deteriorated. In addition, there is a problem that it is difficult to remove the grill housing (1) from the vehicle body panel (5) in case of component failure and assembly failure.

The object of the present invention devised in view of such a problem is to improve the workability by performing the assembly with the minimum force of the operator while the spring is compressed during assembly using the elastic force of the spring provided on both ends of the bar to be folded. .

Another object of the present invention is to improve the serviceability by simply removing the operation while the spring is relaxed by using the elastic force of the spring provided on both ends of the bar to be folded.

An assembly apparatus for an air extractor grill according to the present invention for achieving the above object is installed to traverse both ends of the grill housing, the horizontal bar having a hinge portion in the center; Left and right springs mounted on both left and right ends of the horizontal bar; And a foam pad part provided between the left and right springs and interposed between the vehicle body panel and the grill housing.

The foam pad part includes a slide member having one end fixed to the left and right springs and sliding a through hole of the grill housing, and a foam pad embedded in an installation groove formed in the slide member.

In addition, the end of the slide member is bent to prevent the departure of the slide member to prevent the separation is formed, the flow preventing lip is installed in the inlet of the installation groove of the slide member, the water-tight lip is provided on the outside.

Hereinafter, preferred embodiments of the present invention as described above will be described in more detail with reference to the accompanying drawings.

2 is a front view of the air extractor grill to which the apparatus of the present invention is applied, and FIG. 3 is a cross-sectional view taken along line III-III of FIG. 2, and FIGS. 4A and 4B show main parts of the air extractor grill assembly by the apparatus of the present invention. It is.

2 and 3, a pair of horizontal bars 20 are installed at upper and lower portions of the grill housing 10 while crossing both ends of the grill housing 10.

The horizontal bar 20 is provided with a hinge portion 22 so that the horizontal bar is foldable at the center, and coil springs 32 and 34 are mounted at both ends of the horizontal bar. Therefore, the horizontal bar 20 is normally the coil spring provided at both ends of the left and right, as in the form of the horizontal bar shown in the upper side in Figure 2 is hinged by the elastic force of the spring (32) (34) It is in a state of being folded by a predetermined angle about 22.

The left and right coil springs 32 and 34 are provided with a foam pad part 40 interposed between the vehicle body panel 1 and the grill housing 10.

One end of the foam pad part 40 is fixed to the left and right coil springs 32 and 34, and the slide member 42 sliding the through hole 12 of the grill housing 10, and the slide member ( It is composed of a foam pad 45 embedded in the installation groove 43 formed in 42. At the end of the slide member 42, a separation preventing portion 44 is bent to prevent the slide member from being separated.

A flow preventing lip 46 is installed at an inlet of the installation groove 43 of the slide member, and a watertight rip 47 is provided at an outside thereof.

The operation of assembling and removing the air extractor grill by the assembling apparatus of the air extractor grill according to the present invention configured as described above will be described.

The state before the air extractor grill is assembled is as shown in FIG. 4A and the horizontal bar shown on the upper side of FIG. 2. That is, since the horizontal bar 20 is in a state in which the springs 32 and 34 are relaxed, the horizontal bar 20 is folded around the hinge portion 22 by the elastic force of the springs 32 and 34, and the slide member 42 is grilled. It is led into the inside of the housing 10. At this time, the slide member 42 is supported on the outer surface of the grill housing 10 by the separation prevention portion (44).

When assembling the air extractor grille, the grille housing 10 is first inserted into the vehicle body panel 1 in the assembled position. The assembling hole of the vehicle body panel is preferably formed larger than the grill housing. That is, in the present invention, the assembly is performed in a state where the grill housing is first inserted into the assembling hole of the vehicle body panel without using the interference fitting method.

Then, when the hinge portion 22 of the horizontal bar is pulled downward so that the horizontal bar 20 is in a horizontal state, the slide members 42 provided at both ends of the horizontal bar 20 penetrate the grill housing 10. The body panel 1 is pressed against the foam pad 45 embedded in the installation groove 43 of the slide member 42 while sliding to the outside of the ball 12. At this time, since the assembly is made by a variable length in which the springs 32 and 934 provided at both ends of the horizontal bar 20 are compressed, the foam pad 45 is sufficiently pressed regardless of the thickness of the foam pad 45. Assembly is complete. That is, as the horizontal bar 20 is unfolded in a horizontal state, the springs 32 and 34 are compressed so that the foam pad 45 is supported by the vehicle body panel 1, thereby easily completing the assembly.

On the other hand, when the grill housing is removed, when the hinge portion 22 of the horizontal bar is pulled upward, the horizontal bar shown in the lower side of FIG. 2 and the spring 32 and 34 are relaxed as the spring is relaxed as shown in FIG. 4B. The slide member 42, which was elastically supported by the slide, slides into the grille housing 10, and the foam pad 45 pressed against the vehicle body panel 1 is easily freed from the vehicle body panel 1 while being free. The housing 10 can be removed.

Although the embodiment described above has been described as a horizontal bar installed in the horizontal direction, it is obvious that the same effect can be achieved by the same configuration even when installed in the vertical direction.

As described above, the assembling apparatus of the air extractor grill according to the present invention is moved to the outside of the grill housing by the elastic force of the spring at the time of assembly, while being easily pressed while being pressed on the vehicle body panel, the workability is improved. It works.

In addition, since the removal is simply removed by the method of removing the elastic force of the compressed spring, there is an effect of improving the serviceability of the product.

The present invention is not limited to the specific preferred embodiments described above, and any person skilled in the art to which the present invention pertains can make various modifications without departing from the gist of the present invention as claimed in the following claims. Of course, such changes are within the scope of the claims of the present invention.
