Description

FOB key for vehicle < RTI ID = 0.0 >

The present invention relates to a vehicle pavil key, and more particularly, to a button pavilion for a vehicle, and more particularly, to a button pavilion for a vehicle, Which is firmly fixed in a groove and can be completely sealed to secure waterproofness.

2. Description of the Related Art [0002] In recent years, with the generalization of automobile electronic keys, a driver opens and closes a door from the outside without pressing a separate key insertion or operation button such as a FOB key, A button start technique has been developed which can start the vehicle only by pressing the start button without inserting the Paw key into the key groove. Such a button start technique will be an important trend in future development vehicles As a result, it is known as a very popular field.

The conventional pod key of the vehicle is formed such that the upper side of the button portion where a plurality of button projections are formed on the lower side is exposed to the outside of the upper case to release the locking or unlocking of the side door of the vehicle, The button protrusion is operated downward by depressing the upper side of the exposed button portion.

A plurality of button protrusions provided on a lower portion of the upper case for interlocking with a downward movement of the plurality of button protrusions to generate a predetermined electrical signal; And a lower case coupled to the upper case.

However, according to the conventional paw key for a vehicle, when the user releases the battery and discharges the battery, the button portion is not completely fixed to the button mounting groove formed in the upper case, The button portion may be detached from the button portion attachment groove of the upper case and the seal portion may not be completely sealed between the button portion and the button portion attachment groove, .
