Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to an improvement in a reinforcing structure when a resin material is employed as an outer panel member of a vehicle body such as an automobile.

(Prior Art) In recent years, in order to reduce the weight of vehicle bodies such as automobiles, there has been a tendency for resin plates to be used as a material to replace conventional steel plates. In this way, as disclosed in Japanese Utility Model Application Publication No. 59-32580, a fender is made of resin and a fender is attached to the inner side of the fender adjacent to the door, as disclosed in Japanese Utility Model Application Publication No. 59-32580. It is known that thermal deformation of the fender is prevented by joining a reinforcing member having a coefficient of linear expansion smaller than that of the resin constituting the fender.

(Problems to be solved by the invention) However, although the above conventional method can increase the strength of the part of the fender adjacent to the door, it is made of resin, which causes another problem. . In other words, the resin fender as described above is joined to the outer side of the wheel apron by tightening bolts at a suitable number of locations on its outer periphery, but since the wheel arch of the fender is where the tire is placed, other Unlike the location of the fender, it cannot be joined to the wheel apron, and therefore the tension and rigidity near the wheel arch is low, making it difficult to fully demonstrate the shock absorption ability, which is one of the functions of the fender. The problem is that it can't be done.

On the other hand, by interposing a resin fender liner called a mudguard between the wheel apron and the fender to guard against mud splashed up from the tires while the vehicle is running, the fender is indirectly connected and supported to the wheel apron through the fender liner. There is something. In this case, the tension and rigidity of the fender near the wheel arch is improved by the intervention of the fender liner; however,
The fender side of the fender liner is curved downward in order to avoid interference with the tire, so when an impact is applied to the fender from the outside, the fender liner tends to bend from the bent part and become deformed. Therefore, the degree of contribution to improving the tensile rigidity near the wheel arch is low, and the expected tensile rigidity cannot be obtained.

The present invention has been made in view of the above, and its purpose is to provide a resin inner plate member having a bent portion such as a fender liner to a resin outer plate member such as a fender of a vehicle such as an automobile as described above. In a jointed product, by taking appropriate measures to strengthen the outer panel member in relation to the inner panel member, it is possible to improve the tension and rigidity of the outer panel member, thereby preventing the outer panel member from receiving impacts from the outside. It is an object of the present invention to provide an outer panel member that does not easily deform even when a load is applied.

(Means for Solving the Problems) In order to achieve the above object, the solution of the present invention includes a resin outer panel member, a bent portion disposed inside the outer panel member, and one end of which is disposed inside the outer panel member. Between the joint side of the resin inner plate member joined to the outer plate member
A filling member is placed to fill the area. Further, the bent portion of the inner plate member is provided with a reinforcing rib for preventing deformation of the inner plate member and a positioning stopper portion for positioning the filling member.

(Function) With the above configuration, in the present invention, reinforcing ribs are provided at the bent portions of the resin inner plate member which is disposed inside the resin outer plate member and whose one end is joined to the outer plate member. Therefore, the bent portion does not bend even when a load such as an impact is applied to the outer plate member from the outside, thereby preventing deformation of the inner plate member, and thereby being joined and supported by the inner plate member from the inside. The above-mentioned outer panel member can withstand loads such as impact and has improved tensile rigidity.

Furthermore, since a filling member is arranged between the joint part side of the outer plate member and the inner plate member,
The space between the two is quickly filled with this filling member, preventing deformation of the outer panel member relative to the inner panel member, and this, together with the reinforcing action of the reinforcing ribs, improves the tensile rigidity of the outer panel member. will be further promoted.

Further, since the inner plate member is provided with a stopper portion, the stopper portion prevents the filling member from shifting when a load such as an impact is applied to the outer plate member from the outside. Together with the reinforcing ribs, the filling member can be arranged at a location when the outer panel member is assembled, and thereby the filling member can be easily and reliably arranged at a predetermined position.
