Description

[Detailed Description of the Invention] The present invention relates to a radiator panel lower frame structure of an automobile.

The radiator, which is installed at the very front end of the engine room formed in the front part of the vehicle body, has a structure in which it is supported at the top and bottom by a radiator panel top and a radiator panel lower frame, and has the above-mentioned box-shaped cross section. Both sides of the radiator panel lower frame are connected directly or via brackets to the front ends of the box-shaped side frames provided inside the left and right wheel aprons to maintain the strength of the front part of the vehicle body. This is common (see, for example, Japanese Patent Application Laid-open No. 103657/1983).

The present invention extends the radiator panel lower frame, which is a strength member of the front part of the vehicle body, further in the left and right direction from the connection part with the left and right side frames, and connects the lower part of the bumper to the left and right extension parts, and connects the lower part of the bumper to the left and right extension parts. By connecting the tip of the radiator panel to the lower part of the front fender provided on the outside of the wheel apron, the radiator panel lower frame prevents the bumper and the lower part of the front fender from buckling due to the vehicle body touching the ground when driving on rough roads. This invention is designed to prevent deformation of the vehicle body due to bumper corner impacts, etc., and to improve the strength and rigidity of the front portion of the vehicle body.The present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a wheel apron that forms the side wall of the engine room, 2 is a left and right radiator panel side that is joined and fixed to the front edge flange 1a of the left and right wheel apron 1, and the upper part of the left and right radiator panel side 2 is The left and right radiator panel sides 2 are connected by a radiator panel top 3, and the lower portions of the left and right radiator panel sides 2 are connected by a radiator panel lower frame 4. A radiator (not shown) is installed in the space 5 formed by the radiator, and the upper and lower portions of the radiator are connected and supported by the radiator panel upper 3 and the radiator panel lower frame 4.

As shown in FIG. 2, the radiator panel lower frame 4 has a box-shaped cross section in its central portion, that is, between the left and right radiator panel sides 2, 2, by combining an outer panel 4a and an inner panel 4b. Both ends 4b' are joined and fixed to the lower inner edge of the radiator panel side 2, and both side parts of the radiator panel lower frame 4 are connected to the outer panel 4a and the lower edge 2a of the radiator panel side 2, as shown in FIG. Therefore, it has a box-shaped cross section that is continuous with the central portion.

In the above, conventionally, both side ends of the radiator panel lower frame 4 end at the position a shown by the chain line in FIG. A side frame 6 which is bonded and fixed and has a box-shaped cross section.
As mentioned above, the radiator panel lower frame 4 is connected to the front end of the radiator panel lower frame 4 directly or via a bracket. The lower surface of the bumper 8 is fixed to the lower edge of the extended portion with screws 9, etc., as shown in FIG. 3, and the radiator panel lower This is characterized in that the lower part of the front end of the front fender panel 7 is fixed to the side end of the extension of the frame 4 with screws 10 or the like, as shown in FIG.

Generally, the lower part of the front end of the front fender is extremely weak in terms of strength, and when driving on a rough road with large unevenness, the lower part of the front end of the front fender is very likely to touch the ground, and when it touches the ground, it will immediately buckle and deform. However, in the present invention, as described above, the radiator panel lower frame 4 having a box-shaped cross section is extended laterally, and the front edge of the front fender panel 7 is attached to the extended portion with screws or the like. Since the front fender panel 7 is tightly fixed, the strength of the front part of the front fender panel 7 is significantly higher than that of the conventional one, and the front fender panel 7 due to the ground load is
Buckling of can be prevented.

Furthermore, since the bumper 8 is conventionally only supported on the side frame 6 by stays, etc., the corner portions on both sides of the support by the stays etc. are deformed by a slight impact load, causing deformation of the vehicle body. However, in the present invention, both side portions of the supporting portion of the bumper 8 to the side frame 6 are connected and supported by the radiator panel lower frame 4 having a box-shaped cross section, so the bumper 8 is The impact load applied to the corner portion of the radiator panel is supported by the radiator panel lower frame 4, and problems such as deformation of the vehicle body can be prevented.

Furthermore, in the present invention, the lateral extension of the radiator panel lower frame 4 is constructed by connecting the outer panel 4a and the radiator panel side 2 in a shear field, so the strength and rigidity of the front part of the vehicle body is higher than that of the conventional radiator panel. It is also possible to achieve an effect that is significantly improved compared to a structure in which the lower frame side end portion is simply connected and fixed to the side frame front end portion.

As described above, according to the present invention, the radiator panel lower frame, which has a box-shaped cross section, is extended laterally from the connection part to the side frame, and the bumper and the front end of the front fender panel are connected and fixed to the extension part. This extremely simple structure prevents buckling deformation of the bumper and front fender panel due to ground contact, and deformation of the vehicle body due to bumper corner impact, etc., without adding any new parts, and improves the strength of the vehicle body. It is possible to significantly improve the rigidity, and together with the low cost, it can bring about a great practical effect.
