Description
BACKGROUND OF THE INVENTION
This application claims the priority of Korean Patent Application No. 2001-67079 filed Oct. 30, 2002 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
1. Field of the Invention
The present invention relates to a hood latch assembly for a front end module of a vehicle, and more particularly, to a hood latch assembly for a front end module of a vehicle in which the structure of a cable adopted in a front end module of a vehicle is improved.
2. Description of the Related Art
Typically, a hood is installed in a vehicle to open and shut an engine room where an engine and other parts are installed. The hood is locked and unlocked to and from a body of the vehicle by a hood latch assembly. The locking and unlocking of the hood by the hood latch assembly are performed in multiple steps considering safety in handling.
An example of the hood latch assembly is disclosed in Japanese Patent Application Publication No. 2002-160670. The hood latch assembly includes a locking mechanism enabling a front end portion of a hood to be unlocked from a frame of a body of a vehicle and an unlocking cable extending from the locking mechanism and transmitting a manipulation force input from the outside to the locking mechanism to unlock the locking mechanism.
Japanese Patent Application Publication No. 2000-104430 discloses a hood lock structure for a vehicle having a two-step locking structure. Japanese Utility Model application Publication No. 1993-064372 discloses a hood latch assembly having a hood lock apparatus installed at a frame of a vehicle and coupled to a striker installed at an end portion of a hood and a release cable connecting the hood lock apparatus and a manipulation lever.
The conventional hood latch assembly or hood lock apparatus has a structure in which the hood lock apparatus and the release lever installed inside the vehicle are connected by a cable. As a vehicle has a variety of functions, and various additional apparatuses are installed in the engine room or the size of a vehicle increases, the length of the cable increases so that it is difficult to install and fix the cable connecting the release lever and the hood lock apparatus.
Recently, in manufacturing of vehicles, a front end module has been suggested so that apparatuses which are independently installed in the front side portion of a vehicle, for example, a cooling apparatus such as a radiator, a condenser, and a fan, a head lamp, a bumper, and a horn, can be made into a package and installed on a body frame by a one time work.
However, since in the front end module a hood latch
11
coupled to a striker
12
installed at an end portion of a hood
10
and a release cable
14
connecting a release lever
13
installed inside the vehicle form a single structure, as shown in
FIG. 1
, independency of the front end module
16
fixed to a body frame
15
in an independent package and an efficiency in an installation work are lowered. That is, the hood latch
11
is installed at the front end module
16
and the release lever
13
to manipulate the hood latch
11
is installed inside the vehicle, although the front end module
16
is independently packaged, its independency is lowered by the cable
14
.
