Carrier of automobile front end module

The present invention relates to a carrier of an automotive front end module, and more particularly, by insert-injecting a strength reinforcing member that crosses a carrier front part during carrier injection, thereby improving strength and inserting the side member and the bumper beam in the carrier. The present invention relates to a carrier of an automotive front end module capable of improving productivity by removing nuts and bumper support rails and preventing damage to condenser and radiator due to deformation of the bumper beam during low speed collision.

Recently, a technique of assembling, ie, modularizing an assembly of a plurality of parts in an assembly line has been proposed for the purpose of reducing the number of parts and the number of processes and improving the weight and productivity of the vehicle body.

As a representative example thereof, a front end module (FEM) 1 may be mentioned. As shown in FIG. 1, an integrally formed carrier 10 may include a head lamp 20, a radiator 30, a condenser, and a condenser. 40, the bumper cover 50, the fan shroud 60 and the like and assembled into one component is to be modular.

Here, as shown in FIG. 2, the carrier 10 is described in detail and includes a left and right vertical support part 13 connecting upper and lower horizontal support parts 11 and 12 and the horizontal support parts 11 and 12. A front panel 15 having a substantially rectangular frame shape provided with a cooling module mounting unit 14; And a headlamp support panel 16 extending from left and right sides of the front panel 15 and provided with a headlamp mounting unit 17.

In addition, the carrier 10 has a center support bracket 18 connected to the upper horizontal support 11 and a bumper cover 50 for mounting the bumper cover 50 to improve rigidity of the upper horizontal support 11. Bumper support rail 70 is provided with a mounting portion 71 coupled to the center support bracket 18, and a bumper beam 80 coupled to the vertical support portions 13 on both sides to absorb shock from the front of the vehicle body. And the like.

In addition, the vertical support part 13 is inserted into the insert nut 19 when the carrier 10 is injected so that the bumper beam 80 is coupled to the front side and the side member 90 is coupled to the rear side. do.

However, as shown in FIG. 3, when the impact force is applied to the bumper beam 80 during a collision in front of the vehicle body, the bumper beam 80 is bent and deformed to the rear side. The secondary support is applied to the mounted center support bracket 18, and the center support bracket 18 is also bent and deformed by the impact, and the condenser 40 and the radiator located at the rear side of the center support bracket 18 30) is broken.

In addition, the insert nut 19 inserted into the insert 10 when the carrier 10 is ejected is very difficult to be mounted on the carrier 10 before injection, and the bumper beam 80 is mounted when an impact is applied to the bumper beam 80. The mounting surface of the vertical support 13 to be broken will occur.

An object of the present invention for solving the above problems is to improve the strength of the vertical support portion of the carrier on which the side member and the bumper beam is mounted and to improve the productivity according to the deletion of the insert nut and the bumper support rail and the bumper beam during low-speed collision It is to provide a carrier of the front end module for a vehicle that can prevent damage to the condenser and the radiator due to the deformation of.

The present invention for achieving the above object comprises a front panel provided with a cooling module mounting portion consisting of a horizontal support portion of the upper and lower sides and the left and right vertical support portion connecting the horizontal support portion; A headlamp support panel extending from left and right sides of the front panel and including a headlamp mounting unit; Consists of a connecting portion across the front side of the front panel and a coupling portion formed at both ends of the connecting portion is inserted into the vertical support portion of the both sides and the strength reinforcing member coupled to the bumper beam to the front side and the side member to the rear side; Characterized in that it comprises a carrier.
