Abstract

The present invention provides a hood latch module that can minimize the volume of the latch module by removing a latch spring of a hood latch and by using a torsion spring with a small volume and can reduce noise generated by vibration of the spring by improving an coupling structure of a pawl and the latch. The hood latch module comprises: a release cable configured to transmit a hood opening force; a pawl coupled to one side of the release cable so as to be rotated; a latch configured to interact with rotation of the pawl to be rotated and to couple and fix a hood striker; and a pop-up spring configured to contact with the hood striker at one side thereof. The pop-up spring is deformed as the hood striker is coupled with and fixed to the latch when the hood is closed and applies a restoring force as the hood striker is released to withdraw the hood striker from the latch when the hood is opened.

Claims

1. A hood latch module comprising:

a release cable transmitting a hood opening force;

a pawl rotatably mounted to a base, wherein one end portion of the pawl is coupled to one end of the release cable so as to be rotated by the release cable;

a latch rotatably mounted to the base and interacting with the pawl to be rotated and to receive a hood striker therein; and

a pop-up spring, one end of which is connected to the base and the other end of which selectively contacts with the hood striker,

wherein the other end of the pop-up spring is deformed by the hood striker as the hood striker is engaged with the latch when the hood is closed and applies a restoring force to the hood striker as the hood striker is released from the latch while the hood is opened.

2. The hood latch module of claim 1, wherein the pop-up spring is a torsion spring.

3. The hood latch module of claim 1, further comprising a pawl spring elastically connecting the one end portion of the pawl with the latch, wherein the latch interacts with the pawl to be rotated through the pawl spring.
