Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fender reinforcement structure for an automobile, in which fender panels are supported on both sides of an engine compartment, and a portion of a bumper is accommodated in the front end of the fender panel.

As shown in FIG. 1, a fender panel 2 is supported on both sides of an engine compartment 1 forming a vehicle body, and a front end 21 of the fender panel 2 is supported on both sides of an engine compartment 1 forming a vehicle body.
The bumper 3 protrudes forward from the radiator core support panel 11, which is the front end member of the engine compartment 1, and a part of the bumper 3 is accommodated in the shape of the end 22 with a gap, and the bumper 3 forms the surface of the vehicle body. Conventionally, in an automobile fender structure in which the fender panel 2 is continuous below the fender panel 2, the front end portion 21 of the fender panel 2 remains extended.

However, in such a conventional fender structure, the strength and rigidity of the front end portion 21 of the fender panel 2 tend to be insufficient, and as shown in FIG. Even if the bumper 3 is deformed within the elastic limit and returns to its original state due to a light collision, the fender panel 2 remains permanently deformed and the appearance of the automobile is deteriorated. In particular, when the bumper is made of resin, the range of elastic deformation of the bumper 3 is large, so there is a high possibility of this happening, and there is a problem that even though the bumper 3 is not damaged in a light collision, only the fender panel 2 is deformed. It was hot. Incidentally, this similar structure is found in Utility Model Application Publication No. 75052/1983.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a fender reinforcing structure that prevents the fender panel from being deformed in a light collision and maintains the appearance quality of the automobile.

In order to achieve this object, in the present invention, fender panels are supported on both sides of the engine compartment at the front of the vehicle body, and a portion of a bumper is provided below the front end of the fender panel so that the extensions of the respective surfaces are generally continuous with each other. In such a structure, a reinforcing member is provided at the front end of the fender panel, the tip of which is fixed, the reinforcing member extends inward, and the base end is fixed to the vehicle body, and when the bumper moves rearward, the reinforcing member is provided with a reinforcing member that is fixed to the top surface of the bumper when the bumper moves rearward. The fender reinforcement structure is characterized by forming a guide part that guides the fender panel so as not to interfere with the fender panel, and by reinforcing the front end of the fender panel with a reinforcing member, the strength and rigidity are increased to prevent it from easily deforming, and the reinforcement is reinforced. By guiding the upper part of the bumper in a direction that does not interfere with the fender panel by a guide part of the member, the bumper does not interfere with the fender panel in a light collision and the fender panel is not deformed, thereby maintaining the appearance quality of the automobile.

The present invention will be explained below based on illustrated embodiments.
Note that the same parts as in the conventional example are given the same reference numerals.

3 to 6 show one embodiment of the present invention.

As shown in FIG. 4, an engine compartment 1 is formed at the front of the vehicle body by hood rigid panels 12, 12 on both sides, a radiator core support panel 11 connecting the front ends of the hood rigid panels 12, 12, etc. ing. The inner upper part 23 of the fender panel 2 is fixed to the upper part 13 of the hood rigid panel 12, so that the fender panel 2 is supported in the engine compartment 1. Referring also to FIG. 3, the front end portion 21 of the fender panel 2 is in a state of being overhanging forward from the radiator core support panel 11. Further, on the front surface of the radiator core support panel 11, a reinforcing member 4 in the front-rear direction that projects forward is provided. The reinforcing member 4 is housed inside the front end of the fender panel 2.

As shown in FIG. 5, the reinforcing member 4 is twisted from an elevated proximal end 41 to a horizontal distal end 42, and a main part 44 reinforced with a flange 43 is extended in the front-rear direction. A mounting base portion 45 is formed by bending from the portion 41, and a lower portion of the main portion 44 forms a guide portion 46. The guide part 46 guides the bumper 3 when it moves rearward, and has a plate surface at the front part of the main part 44 and a flange 43 at the rear part.
It is configured to guide the upper surface of the bumper 3. The mounting base 45 is bolted and fixed to the front surface of the radiator core support panel 11, and the tip 42 is connected to the tip 21 of the fender panel 2.
It is bolted and secured to a flange 24 formed on the end 22 of the.

The upper surface 31 of the bumper 3 is accommodated in the end 22 of the front end 21 of the fender panel 2 with a gap therebetween, and the upper surface 31 of the bumper 3 is located below the tip 42 of the reinforcing member 4. That is, in this region, the surface of the bumper 3 and the surface of the fender panel 2 are arranged so that the extensions of their respective surfaces are generally continuous with each other.

In the fender reinforcement structure having the above configuration, the sixth
As shown in the figure, when the bumper 3 is deformed due to a light collision, its upper surface 31 comes into contact with the guide portion 46 of the reinforcing member 4, and is guided by the guide portion 46 and deforms as shown by the dashed line. The fender panel 2 is supported by the reinforcing member 4, and the strength and rigidity of the front end portion 21 is increased, and the bumper 3
Since the bumper does not interfere with the fender panel 2, the fender panel 2 is not deformed and damaged, and the bumper 3 is also deformed within the elastic limit and returns to its original state, maintaining a good appearance of the automobile.

According to this embodiment, the main portion 44 of the reinforcing member 4 is twisted, the front portion of the guide portion 46 is a plate surface, and the rear portion is also a plate surface of the flange 43, so that the upper surface 31 of the bumper 3
Since the bumper 3 is guided in surface contact with the guide portion 46, the contact pressure is dispersed and reduced, so that the bumper 3 is not locally damaged. Since the main portion 44 is twisted, it has a higher strength and rigidity than a case where the entire length is a flat plate, and there is an advantage that the fender panel 2 can be strongly supported.

Next, a second embodiment will be described based on FIG.
This embodiment differs from the first embodiment in that the reinforcing member 4
The mounting base 45 is fixed to the side of the fender panel 2. Other configurations and effects are the first
Since this is the same as the example, the description will be omitted.

According to this embodiment, in addition to the effect achieved in the first embodiment, there is an effect that the workability of attaching the reinforcing member 4 is good. Furthermore, this embodiment is particularly effective when the rigidity of the radiator core support panel 11 or the like is weak.

According to the fender reinforcement structure according to the present invention, a reinforcing member is provided at the front end of the fender panel located in front of the engine compartment, and this reinforcing member guides the deformation of the bumper so that it does not interfere with the fender panel to protect it. The fender panel will not deform under a small load, and in a light collision, it will generally return to its original state even if deformed, and the bumper and fender will remain in good condition, making it possible to minimize the impact even in the case of a large impact.
