Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiator bracket mounting structure.

[0002]

2. Description of the Related Art As a conventional radiator bracket mounting structure, for example, the one shown in FIGS.
(See the official gazette).

A first cross member 1 has a closed cross-section structure in which a member body 2 having a U-shaped cross section and a closing plate 3 are joined. Among the upper and lower joints 1a and 1b of the member main body 2 and the closing plate 3, the upper joint 1a is in the upward state and the lower joint 1b is in the horizontal rearward state. A hood lock stay F is also connected to the front surface of the first cross member 1.

A radiator bracket 5 for supporting the radiator 4 on the closing plate 3 is provided.
(Hereinafter, the bracket 5) is joined. The bracket 5 is composed of a vertical portion 7 and a vertical portion 8 which are bent and formed in an L-shaped cross section through a bending portion 6, and the horizontal portion 8 is formed.
A support hole 9 is formed in the. Beads 10 are formed on the left and right portions of the vertical portion 7 from the upper end 7a to the horizontal portion 8 through the bent portion 6.

The bracket 5 is joined to the closing plate 3 of the first cross member 1 with the vertical portion 7 placed on the lower joint portion 1b. The vertical portion 7 is welded at the three spots S set on the portion other than the bead 10. By joining the vertical portion 7 to the closing plate 3, the horizontal portion 8 is projected to the engine room E side, and the lower portion of the radiator 4 is inserted into the support hole 9 formed in the horizontal portion 8 via the damper D. The formed support pin 4a can be supported.

Since the beads 10 are formed on both the left and right sides of the vertical portion 7 in the state of being attached in this way, the torsional rigidity of the vertical portion 7 can be increased to some extent. Further, since the pair of left and right beads 10 are also formed in the bent portion 6, the torsional rigidity of the horizontal portion 8 can be increased in this respect as well. Furthermore, since the bead 10 is communicated from the bent portion 6 of the vertical portion 7 to the upper end 7a, when the vehicle body together with the bracket 5 is immersed in the electrodeposition coating liquid, the bead 1
When 0, the air A escapes to the upper side, and the spread of the electrodeposition coating liquid on the lower surface of the horizontal portion 8 can be improved.

[0007]

However, in such a conventional technique, although a certain degree of torsional rigidity is ensured, a welding spot S is formed in the portion of the vertical portion 7 where the bead 10 is formed. Cannot be set, so that there is a limit to increasing the joint strength of the vertical portion 7 to the closing plate 3, and it is not possible to obtain sufficient rigidity with respect to the input applied in the twisting direction of the bracket 5. That is,
Since the first cross member 1 itself is twisted according to the left and right suspension inputs, the input in the twisting direction is also applied to the bracket 5 joined thereto, but as described above, the welding spot S is set by forming the bead 10. Since the area is limited and the joint strength of the vertical portion 7 to the closing plate 3 cannot be increased, sufficient torsional rigidity cannot be obtained. Therefore, as a countermeasure for that, it is necessary to increase the plate thickness of the bracket 5, which is one of the causes for increasing the weight of the vehicle body.

The present invention has been made by paying attention to such a conventional technique, and provides a radiator bracket mounting structure capable of sufficiently increasing torsional rigidity.

[0009]

The radiator bracket mounting structure according to the present invention is such that a lower bead including a bent portion is formed in the lower left and right portions of the vertical portion, and the upper central portion of the vertical portion reaches the upper end. A bead is formed to make the upper end of the lower bead and the lower end of the upper bead communicate with each other,
At least the upper vertical portion of the lower bead is joined to the side surface portion of the first cross member.

[0010]

According to the present invention, since the joining spot can be set in the vertical portion above the lower bead, the joining strength of the vertical portion to the first cross member is improved and the torsional rigidity of the radiator bracket is sufficiently enhanced. You can Moreover, since the lower bead and the upper bead are in communication with each other, air can be released even when immersed in the coating liquid, and a pair of left and right lower beads are also formed in the bent portion, so twisting at this point The rigidity is also secured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to FIGS. The same parts as those in the prior art are designated by the same reference numerals, and a duplicate description will be omitted.

The radiator bracket 11 of this embodiment
(Hereinafter, the bracket 11) has an embossed portion 14 whose center portion in the left-right direction has a constant height from the horizontal portion 12 to the lower portion of the vertical portion 13. The width of the embossed portion 14 becomes narrower at the upper portion of the vertical portion 13 and becomes the upper bead 15 as it is and reaches the upper end 13a of the vertical portion 13. Further, lower beads 16 are formed on both left and right sides of the embossed portion 14 below the vertical portion 13. The lower bead 16 extends from the upper end of the embossed portion 14 to the embossed portion 1
It is formed in a range reaching the bent portion 17 of No. 4. Therefore,
The upper end of the lower bead 16 and the lower end of the upper bead 15 are in communication with each other via the embossed portion 14.

A circular recess 18 corresponding to the outer shape of the damper D is formed in the embossed portion 14 of the horizontal portion 12, and a support hole 19 is formed in the bottom of the recess 18.
Partial beads 20 are also formed on the left and right sides of the bent portion 17 other than the embossed portion 14, which contributes to ensuring the torsional rigidity of the horizontal portion 12.

Next, the procedure for attaching the bracket 11 will be described. Since only one upper bead 15 is provided on the upper portion of the vertical portion 13 in the bracket 11, four spots S can be set on the upper portion of the lower bead 16 and the left and right side portions thereof. Therefore, by setting the vertical portion 13 of the bracket 11 on the lower joint portion 1b and welding the spots S, the vertical portion 13 serves as a "side surface portion" of the first cross member 1. Can be joined to the closing plate 3. Then, the damper D is engaged with the support hole 19 provided in the recess 18 of the horizontal portion 12, and the radiator 4 is attached to the damper D.
The support pins 4a formed on the lower part of the are inserted and supported.

The bracket 1 thus mounted
The vertical part 13 of 1 includes the upper part of the lower bead 16,
Since it is joined to the closing plate 3 at the four spots S, the joining strength with respect to the closing plate 3 is improved, and the rigidity against the input in the twisting direction applied to the bracket 11 is sufficiently increased.

Further, the lower bead 16 is also formed on the bent portion 17, and the vertical surface portion 14a of the embossed portion 14 is present on the bent portion 17, and the bent portions on both the left and right sides of the embossed portion 14 are present. Since the partial bead 20 is also formed on the bracket 17, the torsional rigidity of the bracket 11 is enhanced also in these points.

Further, since the lower bead 16 and the upper bead 15 are in communication with each other via the embossed portion 14, even when the bracket 11 is immersed in the coating liquid, the lower bead 16 in this communication state is in communication. The air A on the lower surface of the horizontal portion 12 can be evacuated upward by the upper beads 15, and the coating of the lower surface of the horizontal portion 12 can be improved.

In addition, since the rigidity of the bracket 11 is increased as described above, the elastic performance of the damper D is fully exhibited, and the lower portion of the radiator 4 can be surely soft-mounted, and the damper D Since the side surface contacts the inner surface of the concave portion 18, the elastic performance of the damper D in the horizontal direction can be exhibited.

Although the embossed portion 14 is formed from the horizontal portion 12 to the vertical portion 13 in the above description, the upper end of the lower bead 16 and the lower end of the upper bead 15 may be in communication with each other. Therefore, the embossed portion 14 does not necessarily have to be formed.

Further, the lower bead 16 whose lower portion extends to the bent portion 17 is taken as an example, but the lower portion of the lower bead 16 may extend beyond the bent portion 17 toward the horizontal portion 12 side.

[0021]

The radiator bracket mounting structure according to the present invention has the contents described above, and since the joining spot can be set in the vertical portion above the lower bead, the first portion of the vertical portion can be set. The joint strength to the cross member is improved, and the torsional rigidity of the radiator bracket can be sufficiently increased.

Moreover, since the lower bead and the upper bead are in communication with each other, air can be vented when immersed in the coating liquid, and a pair of left and right lower beads are also formed at the bent portion. Torsional rigidity at points is also secured.
