Insert 13 is fixed by inserting from downward to upward. At this time, the lower side of the hollow insert 13 is formed to protrude outward a predetermined size, so that the protruding portion is fixed to the lower surface of the second fastening hole (12a). After fixing the hollow insert 13, the lower surface of the second fastening hole 12a and the protruding portion of the hollow insert 13 are welded to fix the hollow insert 13. The part marked B in FIG. 2 corresponds to the welding site.

Next, the combination of the conventional hybrid module bracket 10 by injection molding the first plate 11 made of plastic into the second plate 12 in which the hollow insert 13 is inserted into and fixed to the second fastening hole 12a. A structure can be formed.

However, since a gap is generally present between the hollow insert 13 and the second fastening hole 12a in the coupling structure 10 of the conventional hybrid module bracket, it is vulnerable to moisture penetration from the outside. There was a downside. This is a problem arising from manufacturing tolerances and assembly tolerances of the hollow insert 13 and the second plate 12. When the moisture penetrates from the outside as described above, the bonding force of the first plate 11 and the second plate 12 of the dissimilar material is not only weakened, but also a weakening of durability due to component rust occurs. have.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a view schematically showing a coupling structure (100, the coupling structure of the module bracket) of the hybrid module bracket according to an embodiment of the present invention.

Referring to FIG. 3, the coupling structure 100 of the module bracket includes a first plate 110 made of plastic, a second plate 120 made of steel bonded to an upper portion of the first flake 110, and a first plate. And a hollow insert 130 of steel material inserted into and fixed to the 110 and the second plate 120.

The shape of the first plate 110 and the second plate 120 is not specified, and may be variously modified according to the required bracket shape. The first plate 110 may be a plastic material, and is not limited to a specific plastic material. In addition, the second plate 120 may be a steel material, and is not limited to a specific steel material.

A plurality of first fastening holes (not shown) may be formed in the first plate 110, and a plurality of second fastening holes (not shown) may be formed in the second plate 120. The positions of the first fastening hole and the second fastening hole correspond to each other. When the second plate 120 is bonded to the first plate 110, the first fastening hole and the second fastening hole overlap with each other. The hollow insert 130 is inserted into and fixed to the first and second fastening holes.

The bonding of the first plate 110 and the second plate 120 may be performed by injection molding plastic to the second plate 120 of steel in the shape of the first plate 110. In this case, the first plate 110 may be injection molded so that the first fastening hole 111 is formed at a position corresponding to the second fastening hole 121 of the second plate 120.

On the other hand, the injection molding is made under high pressure and high temperature conditions, but because the second plate 120 is formed of a steel material is not affected by such high pressure and high temperature conditions.

4 is a view illustrating the second plate 120 and the hollow insert 130 of FIG. 3, and FIG. 5 is a cross-sectional view of FIG. 3.

4 and 5, the second plate 120 is formed of a steel material, and a second fastening hole 121 is formed on a surface thereof. The second fastening hole 121 may be plural, and FIG. 4 illustrates a state in which one second fastening hole 121 is formed. At this time, the thread 121a is formed on the inner surface of the second fastening hole 121.

In this case, the second plate 120 may be bonded to the first plate 110 (not shown in FIG. 4), and the hollow insert 130 may be inserted into and fixed to the second plate 120. It is also possible to form the first plate 110 (see FIG. 4A above).

The hollow insert 130 corresponds to an insert member having a hollow 131 and is formed of steel. The hollow insert 130 is formed with a protrusion 132 protruding a predetermined size outward on the upper side. Therefore, when the hollow insert 130 is viewed in cross section, it has a “T” shape.

The plastic part 133 is formed along the circumference of the lower side of the hollow insert 130. The method of forming the plastic part 133 on the hollow insert 130 may include injection molding the plastic part 133 to surround the lower side of the hollow insert 130, or correspond to the circumference of the body of the hollow insert 130. After manufacturing the plastic part 133 of the tubular shape having a size to be, it can be made by fitting the hollow insert 130 to the plastic part 133. At this time, the plastic part 133 is not specified to be a specific plastic material, and as described later, rigidity that may cause deformation by the thread 121a formed in the second fastening hole 121 of the second plate 120. It may be formed of a material having a (see FIG. 4b above).

The hollow insert 130 is inserted into and fixed to the second fastening hole 121, at which time the hollow insert 130 is inserted into and fixed downward. At this time, since the hollow insert 130 has a “T” shape as described above, when the hollow insert 130 is inserted into the second fastening hole 121, the protrusion 132 is formed in the second fastening hole. It is caught around the upper surface of 121. Therefore, the entire hollow insert 130 does not exit the second fastening hole 121, but is fixed around the top surface of the second fastening hole 121.

On the other hand, when the hollow insert 130 is inserted into the second fastening hole 121, the plastic part 133 formed on the lower side of the hollow insert 130 is threaded formed on the inner surface of the second fastening hole 121 It is deformed by 121a. This is because the thread 121a is a steel material having rigidity, and the plastic part 133 of the hollow insert 130 is formed of a plastic material having a lower rigidity than the material of the thread 121a.

When the hollow insert 130 is fastened to the second fastening hole 121, the plastic part 133 of the hollow insert 130 is deformed to be in close contact with the thread 121a, so that the hollow insert 130 and the second insert 120 are in close contact with each other. There is no gap (gap) between the fastening holes 121. In addition, since the protrusion 132 of the hollow insert 130 is caught around the upper surface of the second fastening hole 121, a space through which the moisture can penetrate between the hollow insert 130 and the second fastening hole 121 ( Gaps) do not exist.

Thus, when the hollow insert 130 is fastened to the second fastening hole 121, there is no space for moisture to penetrate from the outside of the module bracket, and thus the watertightness of the module bracket can be greatly improved. Penetration can be prevented from weakening durability.

Hereinafter, a method of forming the coupling structure of the hybrid module bracket for forming the coupling structure 100 of the hybrid module bracket according to the embodiment of the present invention will be described.

First, the second plate 120 having the second fastening hole 121 is manufactured. A thread 121a is formed on the inner surface of the second fastening hole 121. The hollow insert 130 is inserted into the second fastening hole 121 and fixed. The plastic part 133 formed on the lower side of the hollow insert 130 is deformed to correspond to the shape of the thread 121a, so that the plastic part 133 and the thread 121a have a somewhat coincident shape (above one step) ).

Next, the first plate 110 is formed by injection molding the plastic on the second plate 120 to which the hollow insert 130 is coupled. At this time, the first plate 110 is injection molded so that the first fastening hole 111 is formed at a position corresponding to the second fastening hole 121 of the second plate 120.

On the other hand, the injection molding is made under high pressure and high temperature conditions, but the second plate 120 and the hollow insert 130 is not affected by such high pressure and high temperature conditions because it is formed of a steel material. However, since the plastic part 133 formed on the lower side of the hollow insert 130 is made of a plastic material, it may be affected by the high pressure and high temperature conditions. That is, a fusion phenomenon may occur with a part of the plastic part 133. When the fusion occurs, the fluidity of the plastic part 133 increases, so that the thread 121a and the plastic part 133 formed in the second fastening hole 121 of the second plate 120 coincide with each other. do. For example, the plastic part 133 having increased fluidity fills the valleys and the floor of the thread 121a. Therefore, when the plastic part 133 is later hardened again, the plastic part 133 is deformed into a form more precisely matched with the thread 121a. Therefore, the watertightness of the module bracket can be further improved (two steps above).

As described above, embodiments of the present invention by forming a screw thread on the inner surface of the fastening hole of the plate made of steel, and by forming a plastic portion on the side of the hollow insert in contact with the screw thread, thereby deforming the plastic part by the screw thread As a result, the watertightness of the hybrid module bracket can be greatly improved.

In addition, by inserting and fastening the hollow insert in the downward direction of the plate there is an effect of eliminating the gap between the hollow insert and the plate.

Therefore, not only the bonding strength between the dissimilar materials of the hybrid module bracket can be maintained, but also a phenomenon in which the durability of the component due to moisture infiltration is weakened can be prevented.

As described above, embodiments of the present invention have been described, but those skilled in the art may add, change, delete, or add elements within the scope not departing from the spirit of the present invention described in the claims. The present invention may be modified and changed in various ways, etc., which will also be included within the scope of the present invention.
