Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a reinforcement structure for a front strut attachment part in an automobile.

[Prior Art] Conventionally, as a reinforcement structure for the front strut attachment part of an automobile, there is a structure shown in FIGS. 4 to 6, in which a strut house 1 is provided to cover the front strut 11. There is.

Further, on the back side of the strut house 1 above the front strut 11, a strut house bracket 2 having a concave surface facing downward is disposed.

Furthermore, a strut house reinforcement 3 is connected to the strut house bracket 2 for reinforcement.

And Struthaus Reinforce 3
As shown in FIG. 6, its upper edge is bent outward and brought into contact with the back surface of the strut house 1, and is placed at the point of contact X at the overlapped part with the peripheral wall of the strut house bracket 2. Spot welds are applied in rows.

In addition, the reference numeral 4 in FIGS. 5 and 6 indicates an upper frame outer, and 5 indicates an upper frame lower.
[Problems to be solved by the invention] However, in such a conventional reinforcement structure for the front strut attachment part, the connection between the strut house bracket 2 and the strut house reinforcement 3 is difficult at the point of impact X. Since it relies on only one row of spot welds, the joint strength is not sufficient.

The present invention aims to solve these problems, and is designed to improve the rigidity of the strut house, and to create a front strut mounting part that achieves sufficiently high bonding strength with a compact structure. The purpose is to provide a reinforcing structure.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the reinforcement structure for the front strut attachment part of the present invention is designed to improve the structure of the front strut attachment part of the present invention. A strut house bracket, which is disposed on the lower surface of the house and has a generally annular peripheral wall portion and a generally disc-shaped upper surface portion connected to the peripheral wall portion, supports the upper part of the front strut together with the strut house; A strut house reinforcement is provided which is coupled to the strut house bracket for reinforcement, and the strut house reinforcement is arranged so that the strut house reinforcement overlaps approximately half of each of the peripheral wall portion and the upper surface portion of the strut house bracket. and the overlapping portion of the strut house reinforcement and the peripheral wall of the strut house bracket is coupled,
Furthermore, the lower surface of the strut house is superimposed on the upper surface of the strut house bracket at the overlapping portion between the upper edge of the strut house reinforcement and the upper surface of the strut house bracket, and It is characterized by the fact that the members are connected.

[Function] In the reinforcement structure of the front strut attachment portion of the present invention described above, the strut house reinforcement is superimposed over approximately half the circumference of the strut house bracket, and is combined at the peripheral wall of the strut house bracket. At the same time, since it is connected to the strut house at the top of the strut house bracket, it is possible to improve the rigidity of the strut house despite its compact structure, and it also allows the upward thrust input from the front strut to be transferred to the strut house and the strut house. The stress is received by the strut house bracket and evenly distributed in the circumferential direction via the strut house bracket, thereby reducing stress.

[Example] The reinforcement structure of the front strut attachment part as an example of the present invention will be explained below with reference to the drawings. Fig. 1 is a longitudinal cross-sectional view showing this structure in comparison with Fig. 5, and Fig. 2 1 is an enlarged longitudinal cross-sectional view of the main part of the structure shown in FIG. 1 in comparison with FIG. 6, and FIG. It is a perspective view, and in FIGS. 1 to 3, the same reference numerals as in FIGS. 4 to 6 indicate substantially the same parts.

As shown in FIGS. 1 and 2, on the back side of the strut house 1 above the front strut 11, a strut house bracket 2 having a concave surface facing downward is disposed in the same manner as in the past. , Strathaus Reinforce 3' is
Unlike the conventional structure, the upper edge portion 3a is bent inward and overlapped with the peripheral wall portion of the strut house bracket 2 and the upper surface portion connected to the peripheral wall portion.

In addition, Strathaus Reinforce 3' is
As shown in FIG. 3, only about half the circumference of the strut house bracket 2 was polymerized.

As shown in FIGS. 2 and 3, there is an overlap between the strut house reinforcement 3' and the peripheral wall of the strut house bracket 2, and an overlap between the upper edge 3'a of the strut house reinforcement 3' and the struts. At the overlapped portion with the upper surface of the house bracket 2, spot welding is performed in rows at dots X and Y, respectively. In this way, the strut house bracket 2 and the strut house reinforcement 3' are connected at two locations, X and Y, and the strength of the connection can be sufficiently increased.

Incidentally, the spot welding at point Y is performed by interposing the upper edge 3'a of the strut house reinforcement 3' between the strut house 1 and the strut house bracket 2, and performing these three parts together. .

Furthermore, the strut house 1 and the strut house reinforcement 3' can be connected by a method other than spot welding.

[Effects of the invention] As detailed above, according to the reinforcement structure of the front strut attachment part of the invention, the joint strength can be increased without increasing the weight or complicating the structure. In addition to sufficiently reinforcing the front strut attachment part, the rigidity of the strut house is improved, and the upthrust input from the front strut is received by the strut house and strut house bracket, and the strut house bracket It is possible to achieve the effect that the stress can be reduced by uniformly distributing it in the circumferential direction.
