Embodiments of the present invention will be described below in detail with reference to the drawings.

1 and 2, reference numeral 1 denotes a radiator core support, and reference numeral 2 denotes a vehicle body front structure. The radiator core support 1 is not attached to the vehicle body front structure 2 as a single unit. As shown in FIG. 2, the radiator core support 1 is previously mounted on the radiator core support 1 with a bumper 3, a bumper stay 4, a lamp 5, and a power steering oil cooler tube. 6,
It is attached to the vehicle body front structure 2 as a module in which the condenser 7, the radiator 8, the fan shroud 9 and the like are assembled.

As the vehicle body front structure 2, a pair of front side members 10 each having a closed cross section are formed on the left and right sides of the engine room E along the front-rear direction. A hood ridge panel 11 is formed above the outer side of the front side member 10, and a hood ridge reinforcement 12 is joined to the outside of the hood ridge panel 11 to form a closed cross section.

As shown in FIG. 3, the radiator core support 1 basically has a radiator core support upper 13 and a radiator core support lower 14 which extend in the vehicle width direction. The support upper 13 and the radiator core support lower 14 have a structure in which the central portions in the vehicle width direction are connected to each other by a hood lock stay 15 extending vertically as a connecting member. The radiator core support 1 has a portion made of metal (white portion in FIG. 3) and a portion made of resin (hatched portion in FIG. 3).

FIG. 4 shows only the portion made of metal. That is, the radiator core support upper 13
The hood lock mounting portion 16 welded to the center of the radiator core support upper 13, the radiator core support lower 14, and the side portions 17 welded to both ends of the radiator core support lower 14 are each made of metal. Others are made of resin. The hood lock mounting portion 16 is in a state where another object is mounted on the radiator core support upper 13, but may be formed integrally with the radiator core support upper 13. Similarly, the side portion 17 may be formed integrally with the radiator core support lower 14.

Each of the radiator core support upper 13 and the radiator core support lower 14 has an open cross-sectional shape having a hat-shaped cross-section opened to the rear side. When manufacturing the radiator core support 1, first, the radiator core support upper 13, the radiator core support lower 14, and the like are set in a cavity space formed between a pair of molds 18. The resin is injected into the empty space and molded.

The hood lock stay 15 and the pillar portion 19 as a connecting member for connecting the upper and lower radiator core support upper 13 and the radiator core support lower 14 with the inner edge of the side portion 17 being included, by means of injection molded resin. And a lamp mounting part 20 for coupling between the side part 17 and both ends of the radiator core support upper 13,
Mainly formed. Two radiator openings 35 are formed between the left and right pillar portions 19 and the hood lock stay 15.

Further, the resin formed by the injected resin is not limited to the portion which largely appears to the outside as described above.
There are also a plurality of oblique ribs (resin reinforcing portions) 21 and 22 which are stretched behind the open cross sections of the radiator core support upper 13 and the radiator core support lower 14. The oblique ribs 21 and 22 enter the open sections of the radiator core support upper 13 and the radiator core support lower 14 from the upper end and the lower end of the hood lock stay 15, and alternately turn between the upper and lower surfaces of the open section. It is formed continuously in the vehicle width direction up to a position reaching both ends in the vehicle width direction while changing.

Since such oblique ribs 21 and 22 are stretched inside the radiator core support upper 13 and the radiator core support lower 14, the integrity of the metal portion and the resin portion is enhanced, and the radiator is lightweight and highly rigid. The core support upper 13 and the radiator core support lower 14 are obtained.

Both the upper and lower oblique ribs 21 and 22 are formed at an angle of 45 ° with respect to the longitudinal direction of the radiator core support lower 14, as in the example of the radiator core support lower 14 shown in FIG. . This angle is most effective in increasing the buckling strength and torsional rigidity of the radiator core support lower 14 and the like.

The upper and lower radiator core support upper 13 and the radiator core support lower 14 are
9, the load in the vertical direction can be transmitted not only through the hood lock stay 15 but also through the pillar portion 19, and the rigidity against the vertical load is improved. Further, since the pillar portion 19 is also connected to the inner edge of the side portion 17, the upper and lower sides and the horizontal portion are connected by the pillar portion 19, and the torsional rigidity around the side portion 17 is also improved.

Further, the radiator core support upper 13
Since the left and right ends and the side portion 17 are connected so as to be filled with the lamp mounting portion 20 having a complicated three-dimensional shape, the torsional rigidity of the entire radiator core support 1 is further improved.

Each oblique rib 2 in the radiator core support upper 13 and the radiator core support lower 14
An abutment 23 is formed at the center of each of the first and second 22.
The abutting portion 23 has a columnar shape having a diameter larger than the thickness of the oblique ribs 21 and 22, and the rear end surface is flat. As shown in FIG. 11, the abutting portion 23 is a portion pressed by the ejector pin 24 to remove the injection-molded oblique ribs 21 and 22 from the mold 18. The thin oblique ribs 21 and 22 that are easily broken when being removed from the mold 18 can also be prevented from being damaged when being removed from the mold 18 by pressing the abutting portion 23 formed at the center thereof.

That is, when the upper and lower ends of the open section are pushed by the ejector pins 24, the open sections of the radiator core support upper 13 and the radiator core support lower 14 are deformed in the opening direction, and both ends of the oblique ribs 21 and 22 are damaged. When the ejector pin 24 directly presses the metal portion at the bottom of the open cross section, the metal portion may be deformed. However, as in the present embodiment, the abutting portions 23 are formed on the oblique ribs 21 and 22. Then, the oblique ribs 21 and 22 are directly pushed out by the ejector pins 24 via the abutting portions 23, thereby avoiding breakage of the oblique ribs 21 and 22 at the time of removing the mold (a state remaining in the mold). it can.

5 and 6, the general portion of the hood lock stay 15 has a U-shaped open cross section that opens to the rear side, and the front portion of the lower end has a rear portion. The radiator core support lower 14 is inclined to the side and connected to the rear end of the radiator core support lower 14. This is because the radiator core support lower 14 has a hat-shaped cross-section, and the radiator core support lower 14 needs to be sandwiched in the mold 18. Therefore, the cross-sectional shape of the lower end of the hood lock stay 15 is changed. For this reason, at the lower end of the hood lock stay 15, in order to prevent a decrease in rigidity due to a change in cross section,
Contrary to the general part, a forward facing flange 25 is formed at each of the left and right ends.

A metal hood lock mounting portion 16 is formed at the center of the radiator core support upper 13 corresponding to the upper end portion of the hood lock stay 15 in the vehicle width direction. And the flapping of the engine hood during running of the vehicle is prevented.

Further, a bent portion 26 is formed at the lower end of the hood lock mounting portion 16 as shown in FIG. 6, and the bent portion 26 is embedded in the upper end of the resin hood lock stay 15. ing. Therefore, when the engine hood (not shown) is closed, the downward load applied to the hood lock mounting portion 16 can be transmitted to the hood lock stay 15 reliably.

Then, the radiator core support upper 1
The radiator core support lower 3 and the radiator core support lower 14 not only have diagonal ribs 21 and 22 formed inside the open cross section on the back side, but also have four locations on the radiator core support upper 13 and a hood lock stay 15 on the radiator core support lower 14. , Including the lower end portions of
29 (see FIGS. 8, 9, and 10). The resin insertion portions 27, 28 and 29 are provided on the oblique rib 2 on the back side.
The resin is also formed so as to wrap around from the first and the second to the front side, and surrounds the cross-sectional periphery of the radiator core support upper 13 and the radiator core support lower.

A part of the oblique ribs 21 and 22 formed on the back side of the radiator core support upper 13 and the radiator core support lower 14 wrap around to the front side, so that the resin feeding portion 2
The formation of 7, 28, 29 further enhances the integrity of the metal portion and the resin portion.

At the bottom of the radiator core support upper 13 and the radiator core support lower 14 at the portions where the resin wrapping portions 27, 28, 29 are formed,
Each has a through-hole-shaped anchor portion 30 (see FIG. 8). Therefore, the resin feeding sections 27, 28, 29 are connected to the radiator core support upper 1 via the anchor section 30.
3 and the radiator core support lower 14, and the radiator core support upper 13 and the radiator core support lower 14 of the resin feeding portions 27, 28, 29 are formed.
The mounting rigidity is increased. Also, this anchor part 3
0 is the abutment 2 formed at the center of the oblique ribs 21 and 22.
3 and the abutment 2 corresponding to the anchor 30
3 also has increased rigidity.

Furthermore, since the oblique ribs 21 and 22 are stretched from the hood lock stay 15 to the open cross sections of the radiator core support upper 13 and the radiator core support lower 14, the above-described resin wrapping portions 27, 28 and 29 are formed. In addition to this, brackets integral with the resin portion can be formed where necessary. For example, a support piece 31 for attaching a front grill (not shown) is formed on each of the four resin insertion portions 27 of the radiator core support upper 13 so as to protrude forward.

Also, the oblique rib 2 corresponding to the resin inflow portion 29 on the right side formed on the radiator core support lower 14
From 2, a support piece 32 is formed to elastically support the U-shaped bent heat radiating portion 6 a of the power steering oil cooler tube 6, another support piece 33 is formed on the left thereof, and a right pillar 19 is also provided on the right pillar 19. A further support piece 34 is formed.

These support pieces 32, 33, 34 are for supporting the heat radiating portion 6 a of the power steering oil cooler tube 6 in a state of protruding into the radiator opening 35. The support piece 32 has two holding claws 32a at the top and bottom,
The intermediate part of the heat radiating part 6a is held. The support piece 33 has one holding claw 33a and holds the vicinity of the distal end of the heat radiating portion 6a. The support piece 34 itself has the shape of a pinching claw, and holds the root of the heat radiating portion 6a. As described above, since the heat dissipation portion 6a of the power steering oil cooler tube 6 is held by the three support pieces 32, 33, and 34,
When traveling on a rough road, the power steering oil cooler tube 6 does not come off even if a strong impact is applied.

Since the middle support piece 32 is formed by the oblique ribs 22 corresponding to the resin entanglement portion 29, even if a large backward wind pressure is applied to the support piece 32 during high-speed running, the support piece 32 is not slid. The oblique ribs 22 do not peel off from the radiator core support lower 14 to the rear side.

A groove 36 for holding one of the non-radiation portions 6b of the power steering oil cooler tube 6 is formed in the pillar portion 19 vertically. Since it is not preferable that the non-heat-radiating portion 6b be in close contact with the inner surface of the groove portion 36, a protrusion 36a (see FIG. 12) is provided inside the groove portion 36 and held in a state of floating from the bottom of the groove portion 36. . Insert the non-radiating portion 6b of the power steering oil cooler tube 6 into the groove 3
By holding the non-heat dissipating portion 6 in the non-radiating portion 6b, the wobbling of the non-radiating portion 6b can be prevented.

The radiator core support 1 having the above-described structure is modularized by assembling the power steering oil cooler tube 6 and the like as described above, and then, as shown in FIG. Metal side portions 17 welded to the left and right sides are attached to the front end of the front side member 10 in the vehicle body front structure 2, and the left and right ends of the radiator core support upper 13 are connected to the hood ridge panel in the vehicle body front structure 2. 1
1 is attached to the front end (not shown).

Radiator core support 1 of this embodiment
Is the radiator core support upper 13 as described above.
A hood lock stay 15 connecting the radiator core support lower 14 and the radiator core support lower 14 is formed of a resin molded together with the radiator core support lower 14 in a mold 18. The resin hood lock stay 15 prevents twist deformation and assembly dimensional error. Since the cause of the occurrence is eliminated, the work of attaching to the vehicle body front structure 2 as described above is also facilitated.

In particular, since the resin lock portion 28 is formed at the lower end of the hood lock stay 15, even if the hood lock stay 15 is made of resin as in the present embodiment, the connection with the radiator core support lower 14 can be achieved. The rigidity of the portion is improved, so that it is possible to withstand a downward impact applied to the radiator core support lower 14 from the hood lock stay 15.

Further, since the side portion 17 attached to the front side member 10 is formed of metal, the radiator core support 1 and the front side member 10 can be firmly connected.

Then, the radiator core support upper 1
Since the radiator core support 3 and the radiator core support lower 14 are also formed of metal, the overall rigidity of the radiator core support 1 is improved, and the sound vibration performance and steering stability of the vehicle body can be improved.

Then, in the radiator opening 35 of the radiator core support 1, the heat dissipating portion 6a of the power steering oil cooler tube 6 is supported by the elastically deformable support pieces 32, 33, 34 made of resin as described above. Even if vibration occurs in the power steering oil cooler tube 6 due to the pressure fluctuation of the oil flowing inside the power steering oil cooler tube 6, the vibration is generated by the support pieces 32, 3
The vibration can be attenuated at 3, 34, and transmission of vibration to the radiator core support 1 can be prevented.

Since the supporting pieces 32, 33, 34 for elastically supporting the power steering oil cooler tube 6 are formed integrally with a part of the resin portion of the radiator core support 1, the supporting pieces 32, 33 are formed in a conventional manner. , 34 need not be prepared as separate parts, and the number of parts can be reduced.

In the above embodiment, the support pieces 32, 3
Although the examples in which the pipes 3 and 34 are formed on the radiator core support lower 14 side and the pillar portion 19 are shown, they may be formed on the resin portion on the radiator core support upper 13 side depending on the piping condition of the power steering oil cooler tube 6. .
