Description

Carrier for automobile

The present invention relates to an automobile carrier, and more particularly, to an automobile carrier which increases the bonding strength of upper and lower panels made of different materials and improves the rigidity and overall durability of the upper panel.

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.

A representative example is the front end module (FEM), which is a modular assembly of components such as a carrier, a headlamp, a radiator, a condenser, a fan shroud, a bumper beam, and a bumper.

Here, the carrier is a hybrid type carrier (hybrid type) that is produced by using a combination of a synthetic resin material and a metal material due to the demand for lightweight vehicle.

As shown in FIG. 1, the conventional hybrid carrier 1 includes a head lamp mounting part having a heat exchanger mounting part 3 on which a heat exchanger such as a radiator and a condenser is mounted at a central part thereof, and a head lamp mounted on both sides thereof. 4) is provided with a lower panel 2 of the synthetic resin material, and the upper panel 5 of the metal material coupled in the horizontal direction on the upper side of the lower panel 2 to reinforce the strength of the lower panel (2).

FIG. 2 is a cross-sectional view taken along line AA of FIG. 1 showing a coupling relationship between the upper panel 5 of the metal material and the lower panel 2 of the synthetic resin material. As shown in the drawing, FIG. A hole 6 having a bent protrusion 6a is formed, and the resin material constituting the horizontal support portion 2a of the lower panel 2 penetrates into the hole 6 during injection molding of the lower panel 2. The upper panel 5 and the lower panel 2 are molded together by being filled in.

However, in order to form the hole 6 having the protrusion 6a bent inwardly in the upper panel 5, it is drilled by a piercing process. Thus, the upper flat portion of the upper panel 5 There is a problem that the rigidity of the upper panel 5 itself is weak due to the hole 6 to be drilled.

Therefore, after the upper panel 5 is manufactured, deformation occurs in the process of loading the upper panel 5 into the injection molding machine to bond the lower panel 2 to the molding, thereby causing a defect.

In addition, when the horizontal support portion 2a of the lower panel 2, which is molded to the hole 6 of the upper panel 5, may be pulled out of the hole 6, the upper and lower panels 5 ( The coupling structure of 2) was weak, and there was a problem in durability.

An object of the present invention for solving the above problems is to form a step rib in the upper panel and to form a plurality of through holes therein to improve the rigidity of the upper panel to prevent defects and the bonding force of the upper and lower panels In addition, the present invention provides an automobile carrier having increased durability and overall durability while improving durability.
