1. Field of the Invention
The present invention relates to a center floor panel assembly for a vehicle, and more particularly, to a center floor panel assembly for a vehicle, which can integrally assemble a center muffler unit.
2. Description of the Prior Art
In a vehicle in the related art, as illustrated in FIG. 1, a muffler unit 60 is arranged on a bottom portion of a floor panel 10 in a vertical direction.
The muffler unit 60, as illustrated in FIGS. 2 and 3, is positioned in a lower portion of a tunnel portion 15 that is formed on a plate surface of the floor panel 10 in the vertical direction, and is connected to the floor panel 10 through a muffler hanger 20 and hanger bars 30 and 40.
The muffler hanger 20 is made of a rubber material having elasticity to absorb vibration and noise of a vehicle exhaust system, and serves to connect the muffler unit 60 to the floor panel 10 together with the hanger bars 30 and 40.
A muffler bar includes the muffler side hanger bar 30 having one end that is fixed to the muffler unit 60 and the other end that is connected to the muffler hanger 20, and the vehicle body side hanger bar 40 having one end that is fixed to the floor panel 10 and the other end that is connected to the muffler hanger 20.
In the vehicle in the related art, however, the muffler unit 60 is not integrally constructed with the floor panel 10, but is spaced apart from the floor panel 10 for a predetermined height, and thus it cannot contribute to the vehicle body stiffness.
Further, in order to prevent the heat injury caused by the muffler unit 60 through which high-temperature exhaust gas passes, it is required to form the tunnel portion 15 with a great height. Accordingly, it is disadvantageous in securing the indoor space and the layout is restricted.
