Mounting Structure of Car Front End Module to body}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body mounting structure of a front end module (FEM) carrier. In particular, the bottom of the FEM carrier is configured in a closed box type so that the front side member (Front Side Member; Vehicle FEM body mounting structure that can increase the rigidity of the body structure by connecting to the (FSM ').

1A to 1F are views for explaining a vehicle body mounting structure of a conventional FEM carrier,

FIG. 1A is a perspective view of an FEM assembly, FIG. 1B is a perspective view of an FEM carrier, FIG. 1C is an exploded perspective view of the FIG. 1B, FIG. 1D is a perspective view of an FSM, and FIG. 1F is a sectional view taken along the line D-D of FIG. 1E.

Referring to the drawings together, the FEM assembly 30 of the vehicle is a FEM carrier (40 in Fig. 1b) made of a steel structure, the headlamp 35, radiator 33, bumper mounted on the FEM carrier 40 (31) and components such as electric fan, condenser, locking assembly.

The FEM carrier (40 in FIG. 1B) is connected by the FSM tip portion (71 in FIG. 1D) of the vehicle body and fastening means (50 in FIG. 1F) such as bolts and nuts, and the main member constituting the skeleton is an upper panel (FIG. 41 of FIG. 1B) and a lower panel (43 of FIG. 1B).

In particular, the lower part (A of FIG. 1B) of the FEM carrier 40 has a lower panel 43 fastening member 44 inside the lower end 41b ′ of both side portions 41b of the upper panel 41. It is structured to be bound laterally by). Portions (C in FIG. 1B) to which the lower side 41b 'of both side portions of the upper panel and the lower panel 43 are coupled are formed with protrusions 41b "at the fastening portions to which the fastening members 44 are coupled. So that it can be easily attached.

1E and 1F, the distal end portion 71 of the FSM 70 is fastened by the fastening means 50 to the fastening portion B on both vertical panels 41b of the FEM carrier. A) has a structure in which only the lower panel 43 made of one steel panel supports the entire structure seated thereon. At this time, the lower panel 43 is seated on the plastic ribs 43a to the top to increase its rigidity, but the structural rigidity in the connection between the both ends of the lower panel 43 and the vehicle body may become unstable. have. In addition, the instability of the connection stiffness deteriorates the dynamic rigidity of the radiator, and adversely affects the subframe stay mounting.

Since the bottom portion C of the vehicle FEM carrier 40 attaches a cooling system such as a radiator 33, an electric fan, a condenser, and the like to the upper portion thereof, structural rigidity of a certain level or higher is required.

There is a problem that the rigidity is lowered.

On the other hand, even when the conventional differential FEM carrier bottom is not an open cross section, but a closed cross section of a box-shaped structure, the closed cross section reaches a portion connecting to the end of the vehicle body side member, and thus is reduced back to an open cross section. There was a problem that the rigidity is lowered.

Accordingly, the present invention is to solve the above conventional problems, the present invention is to form a closed cross-sectional box structure of the bottom of the FEM carrier is connected to the vehicle body, the body mounting rigidity of the FEM carrier is stable, the FEM carrier bottom An object of the present invention is to provide a vehicle mounting structure of a vehicle FEM carrier that can more easily perform tuning operations for vibration control such as a cooling system and an electric fan mounted on the vehicle.

The body mounting structure of the vehicle FEM carrier of the present invention for achieving the above object is a top panel is attached to the center stay extends a predetermined length from approximately the center of the horizontal member in the horizontal direction to the bottom; The lower end of the center stay is connected to the lower end, and the FEM of the vehicle FSM is fastened by fastening means at predetermined positions on both sides, and a FEM comprising a carrier bottom panel on which structures such as a vehicle cooling system and an electric fan are seated on the top. In the body mounting structure of the carrier,

The carrier bottom panel is divided into a carrier bottom out panel and a carrier bottom inner panel, and the bottom of the FEM carrier bottom panel is sealed by binding the carrier bottom inner panel to the upper part of the pedestal that is the lower end of the carrier bottom out panel. In this state, it is connected to the vehicle body FSM, and the shape of the inner bottom panel of the carrier is coupled to the lower end of the pedestal upper end of the carrier bottom out panel so that a space of a certain size is formed on the inner side, and the upper end of the lower panel of the FSM is It is bent to contact the bottom surface is characterized in that the fastening means is formed on the bottom of the FSM, characterized in that the body mounting rigidity of the FEM carrier is stabilized, such as cooling system or electric fan mounted to the top of the carrier bottom The tuning operation for vibration control becomes easy.
