Description

[Detailed Description of the Invention] This invention relates to an improvement in the front bumper mounting structure of an automobile.

Conventionally, a bumper arm 1 for supporting a front bumper of an automobile has a structure as shown in FIG.
It is attached near the front end of the front side member 2, but the rear end penetrates the radiator support 3 and projects into the engine room 4, and bolts 5 and nuts 6 are attached at this projecting portion.
It is tightened and fixed. In the figure, numeral 7 indicates a bumper reinforcement hose, and 8 indicates a bumper cover.

In the conventional front bumper mounting structure as described above, when replacing the bumper assembly, for example, in order to remove the bolts 5 and nuts 6, it is necessary to remove the battery near the radiator support 3 in the engine compartment 4. , the air cleaner (not shown) had to be removed, making the work extremely troublesome. In addition, since the bumper arm 1 passes through the radiator support 3, hot air in the engine room 4 enters the front surface of the radiator support 3 through the through hole 9, thereby reducing the cooling efficiency of the radiator.

Also, when a cross member is connected to the lower side of the front end of the front side member 2, the front side member 2
The position of is raised by the height of the cross member.
For this reason, a front side member through hole is formed in the radiator support, but in this case, there is an inconvenience that hot air in the engine compartment flows around the front side of the radiator support through the through hole.

This idea was made to solve the above-mentioned conventional inconveniences, and it not only improves work efficiency when replacing bumper assemblies, but also prevents hot air in the engine room from going around to the front of the radiator. The purpose of the present invention is to provide a front bumper mounting structure for an automobile.

This invention includes a bumper arm whose rear end is attached to the upper surface of the front end of a front side member by a bolt passing through the front side member in the vertical direction, and supports a front bumper at the front end;
a cross member intersecting a front end portion of the front side member, the rear end of the bumper arm attached to the front side member is positioned forward of the radiator support; The above object is achieved by making the cross member intersect with the front end side surface of the front side member at a position forward of the radiator support and at the same height.

Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, the same or corresponding parts as in the conventional example shown in FIG. 1 are given the same reference numerals as in FIG. 1, and the explanation thereof will be omitted.

FIG. 2 is an exploded perspective view showing the main parts of an embodiment of the automobile front bumper mounting structure according to the present invention, and FIG. 3 is an enlarged sectional view showing the main parts of the same embodiment.

In this embodiment, as shown in the figure, a bumper arm 1 whose rear end is attached to a front side member 2 and supports a front bumper at its front end.
, the rear end of which is attached to the front side member 2 is positioned in front of the radiator support 3.

That is, at the front position of the radiator support 3, the bumper arm 1 sandwiches the gusset 11 attached to the joint between the front side member 2 and the cross member 10, so that the bumper arm 1 extends between the front and rear sides.
It is attached to the upper surface of the front side member 2 with bolts 5 and nuts 6. Here, the bolt 5 is a through bolt having a length that vertically passes through the front side member 2, so that the external force applied to the front bumper is received by the upper and lower surfaces of the front side member 2. The front side member 2 and the cross member 10 intersect at the same height and are joined together.

Reference numeral 12 in the figure is an absorber made of urethane foam covered by the bumper cover 8, 13 is a bolt for attaching the bumper arm 1 to the front side member 2 via the gusset 11, and 14 is
indicates a through hole formed in the radiator support 3 through which the rising portion 15A of the skin 15 of the front side member 2 passes.

In the above embodiment, the bumper arm 1 is attached to the front side member 2 together with the gusset 11, but this is not necessarily limited to attachment together with the gusset 11.

As described above, the present invention is configured such that the rear end of the bumper arm is attached to the upper surface of the front end of the front side member at a position forward of the radiator support with a bolt passing through the front side member in the vertical direction. Removal work, such as when replacing an assembly, can be done without removing the battery or air cleaner in the engine compartment, and the cross member can be installed at the same height on the side of the front end of the front side member at a position forward of the radiator support. Since they are crossed and connected at the cross position, the height of the front side member can be lowered by the height of the cross member, and therefore there is no need to provide a through hole for the front side member in the radiator support.
Furthermore, since the bumper arm is attached to the front side member at a position forward of the radiator support, there is no need to provide a through hole for the bumper arm, which prevents hot air from inside the engine room from going around to the front of the radiator. It has the excellent effect of preventing
