ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a vibration protected tailgate structure for an automobile, and more particularly to a vibration protected tailgate structure adapted for use to prevent vibration caused by the vibration of an automobile and thereby to reduce noise generated by the tailgate.
2. Description of the Prior Art
Generally, an automobile is mounted with a plurality of doors openable and closeable for passengers to get in and out, cargo to be loaded and unloaded, and a tailgate is installed at a “one-box car” such as a jeep or the like. The tailgate
50
is hinged to an upper end of roof panel (R) at the rear side of body (B), and when tailgate
50
is opened or closed, cargo can be received or taken out from the rear side of the automobile, as illustrated in FIG.
4
.
Between tailgate
50
and body (B), there is installed a waterproof weather strip and a guide bumper to prevent shaking and swaying of the tailgate.
As illustrated in
FIG. 5
, tailgate
50
is mounted with a first guide bumper
53
fixed at a longitudinal end thereof by bolts
52
, and a second guide bumper
56
disposed at body (B) for restricting “H” and “L” directions by allowing the first guide bumper
53
and first/second contact surfaces
54
and
55
to adhere when tailgate
50
is closed.
In other words, when tailgate
50
is closed, the first and second guide bumpers
53
and
56
closely adhere to prevent tailgate
50
from vibrating in the “H” and “L” directions.
However, the problem is that the tailgate generates noise due to its vibration while an automobile is running because vibration generated in the opening direction of the tailgate cannot be restricted in case the mutually adhered first and second guide bumpers are intended for use in restricting the vibration of the tailgate.
SUMMARY OF THE INVENTION
The present invention is disclosed to solve the aforementioned problem and it is an object of the present invention to provide a vibration protected tailgate structure for an automobile which is constructed to reduce generation of noise occurring in the opening direction of the tailgate.
In accordance with the object of the present invention, there is provided a vibration protected tailgate structure for automobiles, the structure including first and second guide bumpers, respectively, mounted at the tailgate and a body and contacted when the tailgate is closed to thereby restrict vibration of the tailgate, the structure comprising:
a hitching groove formed on one of the bumpers; and
hitching means hitched by the hitching groove when the tailgate is closed to restrict vibration of the tailgate and formed on the other bumper for being hitched by the hitching groove when the tailgate is closed to restrict the vibration of the tailgate and detached from the hitching groove when the tailgate is opened.
