Description
Technical Field
The present invention relates to a vehicle body side portion structure including a rear wheel house that covers an outer side of a rear wheel.
The present application claims priority based on japanese patent application No. 2019-035552 filed on 28/2/2019, the contents of which are incorporated herein by reference.
Background
A rear wheel house that covers the outer side of the rear wheel is provided at the rear side portion of the vehicle. The rear wheel house is generally configured by joining a rear wheel house inner member as a plate material disposed on the inner side in the vehicle width direction and a rear wheel house outer member as a plate material disposed on the outer side in the vehicle width direction to each other by welding or the like. Further, a side outer panel constituting an appearance surface of the vehicle body is joined to an outer side of the rear wheel house.
In recent years, in such a vehicle body side portion structure, in order to further improve steering stability and more favorably receive an impact load from the side of the vehicle body, it is desired to improve rigidity around the rear wheel house. As a countermeasure, a technique has been proposed in which a wheel house reinforcing member is joined to the upper surface side of the rear wheel house, and a reinforced closed cross section is formed between the wheel house reinforcing member and the rear wheel house (see, for example, patent document 1).
The rear wheel house of patent document 1 is formed by joining a rear wheel house inner member and a rear wheel house outer member, which are substantially arc-shaped, to each other, and a wheel house reinforcing member is joined to an upper surface side of the rear wheel house outer member. The reinforced closed section is formed by surrounding the wheel house reinforcing member and the rear wheel house outer side member.
Specifically, the rear wheel house inner and outer members have a base wall covering the outer side of the outer peripheral surface of the rear wheel and rising walls (flange portions) extending from the end portions of the base wall toward the radial outer side of the rear wheel, and the rising walls are butted against each other and joined by spot welding or the like. In addition, the wheel house reinforcing member has: a reinforcing member main body portion for forming a reinforcing closed section with the rear wheel house outer side member; an outer flange portion joined to an outer surface of the base wall at an outer end of the reinforcing member body portion in the vehicle width direction; and an inner flange portion joined to a rising wall of the rear wheel house inner at an inner end in the vehicle width direction of the reinforcement member body portion. The inner flange portion is welded and fixed to a portion of the rising wall of the rear wheel house inner, which is closer to the door opening side than a joint portion with the rear wheel house outer. Thereby, the area of the reinforced closed cross section is largely ensured.

Problems to be solved by the invention
However, in the vehicle body side portion structure described in patent document 1, the inner flange portion of the wheel house reinforcing member is welded and fixed to a portion of the rising wall of the rear wheel house inner closer to the door opening side than the joint portion with the rear wheel house outer, and therefore the outside of the joint portion of the rear wheel house inner and the rear wheel house outer is covered in a bag shape by the wheel house reinforcing member. Therefore, the wheel house reinforcing member cannot join the inner flange portion to the rising wall of the rear wheel house inner unless welding (spot welding) of the rear wheel house outer and the rear wheel house inner is completed. Therefore, in the case of the vehicle body side portion structure described in patent document 1, three members, that is, the wheel house reinforcing member, the rear wheel house outer side member, and the rear wheel house inner member, cannot be joined efficiently, and improvement in efficiency of the joining work is desired.
An aspect of the present invention provides a vehicle body side portion structure capable of efficiently joining three members, namely, a wheel house reinforcing member, a rear wheel house outer side member, and a rear wheel house inner side member.
Means for solving the problems
The vehicle body side portion structure of the present invention employs the following structure.
(1) The vehicle body side portion structure of the present invention includes: a rear wheel house covering an outer side of the rear wheel; a side outer panel disposed outside the rear wheel house and forming a closed cross section extending substantially along the outer peripheral surface shape of the rear wheel between the side outer panel and the rear wheel house along the peripheral edge of the door opening; and a wheel house reinforcing member that forms a reinforced closed cross section between an inner side of the closed cross section and the rear wheel house, the rear wheel house including a rear wheel house inner member and a rear wheel house outer member, the rear wheel house inner member being a plate material arranged on an inner side in a vehicle width direction, the rear wheel house outer member being a plate material arranged on an outer side in the vehicle width direction, the rear wheel house inner member having an inner member base wall facing an outer peripheral surface of the rear wheel and an inner member rising wall extending from a vehicle width direction outer end of the inner member base wall toward a radial outer side (a door opening side) of the rear wheel, and the rear wheel house outer member having an outer member base wall facing the outer peripheral surface of the rear wheel and an outer member rising wall extending from a vehicle width direction inner end of the outer member base wall toward the radial outer side of the rear wheel, the inner member rising wall and the outer member rising wall being joined to each other, the outer member base wall is disposed offset toward the axial center side of the rear wheel with respect to the inner member base wall, and the wheel house reinforcing member includes: a reinforcing member main body portion that forms the reinforcing closed cross section with the outer member base wall; an outer joint portion that is joined to an outer surface of the outer base wall at a vehicle width direction outer side portion of the reinforcement member main body portion; and an inner joint portion extending from a vehicle width direction inner end of the reinforcement member main body portion toward a radially outer side of the rear wheel, the inner joint portion being disposed on a back surface of a joint surface of the outer member rising wall to the inner member rising wall, and the inner joint portion being joined together with the outer member rising wall and the inner member rising wall in a state of being overlapped in three.
According to the structure of the aspect (1), in the wheel house reinforcing member, the outer joint portion is joined to the outer surface of the outer member base wall of the rear wheel house outer member, and the inner joint portion is joined together with the outer member standing wall of the rear wheel house outer member and the inner member standing wall of the rear wheel house inner member in a state where three sheets are overlapped. In this case, the inner joint portion of the wheel house reinforcing member can be easily joined by spot welding in a state where three sheets of the outer member rising wall and the inner member rising wall are overlapped with each other.
Further, when the wheel house reinforcing member and the side outer panel are joined to the rear wheel house, a closed cross section extending substantially along the outer peripheral shape of the rear wheel (along the peripheral edge of the door opening) is formed by the rear wheel house and the side outer panel, and a reinforced closed cross section formed by the rear wheel house outer and the wheel house reinforcing member is formed inside the closed cross section. Further, the outer member base wall is offset toward the axial center side of the rear wheel from the inner member base wall, whereby the area for reinforcing the closed cross section can be increased. As a result, the rigidity and strength around the rear wheel house can be efficiently improved while reducing the weight of the vehicle regardless of the thickness of the steel plate.
(2) In the aspect (1), the rear wheel house outer may have an outer member base wall formed substantially parallel to an outer peripheral surface of the rear wheel in a cross section along the vehicle width direction, an inclined wall inclined toward the axial center side of the rear wheel toward the vehicle width direction outer side provided at an outer edge portion of the outer member base wall in the vehicle width direction, and an inclined engagement wall engaged with the inclined wall provided at the side outer panel.
In this case, since the outer member base wall of the rear wheel house outer member is formed substantially in parallel with the outer peripheral surface of the rear wheel, the outer member base wall can be brought sufficiently close to the rear wheel without causing interference with the rear wheel. Therefore, the sectional area of the reinforced closed section can be sufficiently secured in the limited space in the peripheral area of the rear wheel.
In the case where the outer member base wall that is bent forward and rearward of the vehicle is disposed offset toward the axial center side of the rear wheel with respect to the inner member base wall, the degree of bending increases (the curvature decreases), and it becomes difficult to press-form the bending angle of the edge portion of the outer member base wall on the outer side in the vehicle width direction to be substantially perpendicular. In the present configuration, however, an inclined wall is provided at an edge portion of the outer member base wall on the outer side in the vehicle width direction, and an inclined joint wall of the side outer panel is joined to the inclined wall. Therefore, in the case of this configuration, it is not necessary to sharply bend the edge portion of the outer member base wall on the vehicle width direction outer side at a substantially right angle, and the rear wheel house outer member can be easily processed.
(3) In the aspect (2), a bent flange portion bent toward the axial center side may be provided at an end edge of the inclined joint wall of the side outer panel such that an inner surface and an outer surface of the end edge become planes substantially orthogonal to the axial center of the rear wheel.
In this case, since it is not necessary to precisely cut the end portion of the inclined joint wall of the side outer panel, the side outer panel can be easily processed. In addition, the bent flange portion is formed by bending the end portion of the inclined joint wall, whereby the dimensional accuracy of the end portion of the inclined joint wall can be easily improved. Further, since the bent flange portion is bent toward the axial center of the rear wheel, the dust-proof sealant can be easily applied to the portion where the end portion of the inclined joint wall and the end portion of the inclined wall meet each other on the back surface side of the bent flange portion. Specifically, when the dust-proof sealing agent is applied, the bent flange portion can be used as a guide for applying the dust-proof sealing agent, and the protrusion of the dust-proof sealing agent from the end portion of the inclined wall can be hidden by the bent flange portion.
(4) In the aspect (2) or (3), a garnish that covers the vehicle width direction outer side of the inclined joint wall may be attached to the side outer panel.
In this case, the joint trace or the like on the inclined joint wall is covered by the garnish. Therefore, the appearance when viewed from the outside is improved, and the clothes of the occupant can be prevented from swinging at the free end of the bent flange portion.
(5) In any one of the above (2) to (4), a rocker reinforcing member at the rear of the rocker may be disposed at the front of the rear wheel house, a rear edge portion of the rocker reinforcing member may be coupled to a front edge portion of the wheel house reinforcing member by a bolt, and a rear edge portion of the rocker reinforcing member may be coupled to the inclined wall and the inclined joint wall in a state of being sandwiched between the inclined wall and the inclined joint wall on the vehicle width direction outer side.
In this case, the front portion of the rear wheel house is firmly joined to the rear portion of the rocker reinforcing member at a plurality of locations on the vehicle width direction outer side. Further, the reinforced closed cross section formed by the wheel house reinforcing member can be made continuous with the closed cross section of the rocker with high rigidity, and therefore the rigidity from the periphery of the rear wheel house to the rocker can be efficiently improved.
Effects of the invention
In the aspect of the present invention, the inner joint portion of the wheel house reinforcing member is joined together with the outer member rising wall of the rear wheel house outer member and the inner member rising wall of the rear wheel house inner member in a state where three sheets are overlapped, so that the three members of the wheel house reinforcing member, the rear wheel house outer member and the rear wheel house inner member can be efficiently joined by spot welding. Therefore, when the vehicle body side portion structure of the present invention is employed, the work efficiency at the time of manufacturing can be improved.

As shown in fig. 5 and 6, the rear wheel house 11 includes a rear wheel house inner 11I as a plate material disposed on the inner side in the vehicle width direction and a rear wheel house outer 11O as a plate material disposed on the outer side in the vehicle width direction. The rear wheel house inner 11I has: an inner member base wall 11I-b facing the outer peripheral surface of the rear wheel Wr; and an inner member rising wall 11I-a extending from a vehicle width direction outer end of the inner member base wall 11I-b toward a radially outer side of the rear wheel Wr. The rear wheel house outer side member 11O has: an outer member base wall 11O-b opposed to the outer peripheral surface of the rear wheel Wr; and an outer member rising wall 11O-a extending from the vehicle width direction inner end of the outer member base wall 11O-b toward the radially outer side of the rear wheel Wr. The outer member base wall 11O-b is disposed offset to the axial center O side of the rear wheel Wr from the inner member base wall 11I-b, and in the rear wheel house inner member 11I and the rear wheel house outer member 11O, the inner member rising wall 11I-a and the outer member rising wall 11O-a are overlapped with each other, and the inner member rising wall 11I-a and the outer member rising wall 11O-a are joined to each other by spot welding.
An inner member base wall 11I-b of the rear wheel house inner 11I is inclined gently downward toward the vehicle width direction inner side, and an inner cover wall 11I-c bent downward and extending is provided extending from an extending end of the inner member base wall 11I-b. The inner cover wall 11I-c covers the vehicle width direction inner side of the rear wheel Wr, and prevents splash and the like from the rear wheel Wr in the vehicle body inner side direction.
On the other hand, the outer member base wall 11O-b of the rear wheel house outer 11O is offset toward the axial center O of the rear wheel Wr at a position closer to the outer peripheral surface of the rear wheel Wr than the inner member base wall 11I-b of the rear wheel house inner 11I. That is, the outer member rising wall 11O-a of the rear wheel house outer 11O extends downward from the overlapping portion (joint portion) of the outer member rising wall 11O-a and the inner member rising wall 11I-a of the rear wheel house inner 11I, and the outer member base wall 11O-b extends while being bent at a substantially right angle outward in the vehicle width direction from the lower end of the outer member rising wall 11O-a. As shown in fig. 5 and 6, the outer member base wall 11O-b is formed substantially parallel to the outer peripheral surface of the rear wheel Wr in a cross section along the vehicle width direction.
A region of the outer member rising wall 11O-a of the rear wheel house outer member 11O on the upper end side of the overlapping portion (joint portion) of the outer member rising wall 11O-a and the inner member rising wall 11I-a is bent in a crank shape outward in the vehicle width direction and then extends straight upward. Hereinafter, the portion extending straight is referred to as an upper-end flange portion 11O-af 1, and the portion where the outer member rising wall 11O-a and the inner member rising wall 11I-a overlap is referred to as an intermediate flange portion 11O-af 2.

The outer flange portion 14O constitutes an outer joint portion that is joined to the upper surface of the outer member base wall 11O-b of the rear wheel house outer 11O, and the inner flange portion 14i constitutes an inner joint portion that is joined to the vehicle width direction outer side surface of the outer member standing wall 11O-a of the rear wheel house outer 11O. The reinforcing member main body portion 14h forms a reinforcing closed cross section 22 of a substantially rectangular shape between it and the rear wheel house outer side 11O. The inner flange portion 14I is superimposed on the rear side (the outer side in the vehicle width direction) of the joint surface of the intermediate flange portion 11O-af 2 of the outer member rising wall 11O-a that is joined to the inner member rising wall 11I-a of the rear wheel house inner 11I. The inner flange portion 14I (inner joint portion) is joined by spot welding in a state where three sheets are overlapped together with the intermediate flange portion 11O-af 2 of the outer member rising wall 11O-a and the inner member rising wall 11I-a.
The rocker reinforcing member 50 integrally connected to the rear end portion of the rocker 10 is bent and extended toward the rear upper side so as to overlap the upper surface side of the front region of the rear wheel house 11. As shown in fig. 6, the rocker reinforcement member 50 has: an upper wall 50u that overlaps the upper wall 14u of the wheel house reinforcing member 14; a side wall 50s bent downward from an inner end of the upper wall 50u in the vehicle width direction and extending; an inclined flange portion 50q inclined toward the axial center o side of the rear wheel Wr from the end portion of the side wall 50s toward the outside in the vehicle width direction; and a raised flange portion 50p extending from an inner end portion of the upper wall 50u in the vehicle width direction toward a radially outer side of the rear wheel Wr.
The inclined flange portion 50q of the rocker reinforcing member 50 is joined to the inclined wall 11O-c and the inclined joint wall 20q of the side outer panel 15 by spot welding in a state sandwiched between the inclined wall 11O-c of the rear wheel house outer 11O and the inclined joint wall 20 q. The upright flange portion 50p of the rocker reinforcement member 50 is joined to the upright wall 20p and the upper end flange portion 11O-af 1 by spot welding in a state of being sandwiched between the upright wall 20p of the side outer panel 15 and the upper end flange portion 11O-af 1 of the rear wheelhouse outer 11O.
Further, a bolt insertion hole 51 is formed in the substantially center of the upper wall 50u of the rocker reinforcement member 50 in the vehicle width direction, and a weld nut 52 is provided on the upper side of the bolt insertion hole 51. Similar bolt insertion holes 53 are formed in the upper wall 14u of the wheel house reinforcing member 14 at positions corresponding to the bolt insertion holes 51 of the rocker reinforcing member 50. A sleeve 24 through which the shaft portion of the fastening bolt 23 passes is interposed between the upper wall 14u of the wheel house reinforcing member 14 and the outer member base wall 11O-b of the rear wheel house outer member 11O.
The shaft of the fastening bolt 23 is fastened and coupled to the weld nut 52 from below the outer member base wall 11O-b through the bolt insertion hole 56, the sleeve 24, and the bolt insertion holes 53 and 51.
Thus, the rocker reinforcing member 50 is integrated with the wheel house reinforcing member 14 and the rear wheel house outer 11O via the fastening bolt 23. As a result, the reinforced closed cross section 22 formed by the wheel house reinforcing member 14 and the rear wheel house outer 11O is continuous with the closed cross section of the rocker 10.
Fig. 7 is a partially cut-away perspective view of the wheel house portion 15b of the side outer panel 15 in which a portion corresponding to the section VII-VII in fig. 2 is formed as a cross section.
As shown in fig. 4, an inclined joint wall 20q and a bent flange portion 20r are disposed at the outer edge portion in the vehicle width direction of the front region 15 b-1 of the wheel cover portion 15 b. The inclined joint wall 20q has a weld mark (joint mark) formed on its surface when spot-welded to the inclined wall 11O-c of the rear wheel house outer 11O. Therefore, as shown in fig. 2 and 7, a garnish 60 covering the vehicle width direction outer side of the inclined joint wall 20q and the bent flange portion 20r is attached to the vehicle width direction outer edge portion of the front portion region 15 b-1 of the wheel cover portion 15 b.
As described above, the vehicle body side portion structure of the present embodiment forms the closed cross section 21 extending substantially along the outer peripheral surface shape of the rear wheel Wr at the peripheral edge of the door opening by the rear wheel house 11 and the side outer panel 15, and forms the reinforced closed cross section 22 formed by the rear wheel house outer 11O and the wheel house reinforcing member 14 inside the closed cross section 21. Therefore, when the vehicle body side portion structure of the present embodiment is employed, the rigidity and strength around the rear wheel house can be efficiently improved.
In the vehicle body side portion structure of the present embodiment, the inner flange portion 14I of the wheel house reinforcing member 14 is overlapped with the rear surface of the joining surface with the inner member rising wall 11I-a of the rear wheel house outer side member 11O of the outer member rising wall 11O-a joined to the rear wheel house inner member 11I, and the inner flange portion 14I is joined together with the outer member rising wall 11O-a and the inner member rising wall 11I-a in a state where three sheets are overlapped. Therefore, the three members of the wheel house reinforcing member 14, the rear wheel house outer 11O, and the rear wheel house inner 11I can be efficiently joined by spot welding. Therefore, when the vehicle body side portion structure of the present embodiment is employed, the work efficiency at the time of manufacturing can be improved.
In the vehicle body side portion structure of the present embodiment, the outer member base wall 11O-b is offset toward the axial center O side of the rear wheel Wr from the inner member base wall 11I-b, and therefore the outer member base wall 11O-b can be sufficiently close to the rear wheel Wr. Therefore, the cross-sectional area of the reinforced closed cross-section 22 can be sufficiently secured in a limited space in the area around the rear wheel Wr, and the rigidity around the rear wheel can be efficiently improved.
In the vehicle body side portion structure of the present embodiment, the outer member base wall 11O-b of the rear wheel house outer 11O is formed substantially parallel to the outer peripheral surface of the rear wheel Wr in a cross section along the vehicle width direction, and the inclined wall 11O-c is provided at the vehicle width direction outer edge portion of the outer member base wall 11O-b. Also, the wheel house portion 15b of the side outer panel 15 is provided with an inclined engagement wall 20q to which the inclined wall 11O-c is engaged. In the case of this configuration, since the outer member base wall 11O-b is formed substantially parallel to the outer peripheral surface of the rear wheel Wr, the outer member base wall 11O-b can be brought sufficiently close to the rear wheel Wr without causing interference with the rear wheel Wr. Therefore, the sectional area of the reinforced closed cross section 22 can be sufficiently secured in a limited space in the area around the rear wheel Wr, and the rigidity around the rear wheel house can be efficiently improved. Thus, in the case of the present embodiment, the rear side door opening 18 is not narrowed, and therefore, the riding ability of the occupant is not sacrificed.
Further, if the outer member base wall 11O-b bent forward and backward of the vehicle is disposed offset to the axial center O side of the rear wheel Wr from the inner member base wall 11I-b, the degree of bending becomes large, and it becomes difficult to press-form the bending angle of the outer edge portion of the outer member base wall 11O-b in the vehicle width direction to be substantially perpendicular. However, in this structure, the inclined wall 11O-c is provided at the outer edge portion of the outer member base wall 11O-b in the vehicle width direction, and the inclined joint wall 20q of the side outer panel 15 is joined to this inclined wall 11O-c. Therefore, in the case of this configuration, it is not necessary to sharply bend the edge portion of the outer member base wall 11O-b on the vehicle width direction outer side at substantially right angles, and therefore, the rear wheel house outer 11O can be more easily processed.
In addition, in the vehicle body side portion structure of the present embodiment, since the bent flange portion 20r is provided at the end edge of the inclined joint wall 20q of the side outer panel 15, it is not necessary to cut the end portion of the inclined joint wall 20q of the side outer panel 15 with high accuracy in manufacturing. Therefore, the processing of the side outer panel 15 becomes easier. In the configuration of the present embodiment, since the bent flange portion 20r can be formed by bending the end portion of the inclined joint wall 20q, the dimensional accuracy of the end portion of the inclined joint wall 20q can be easily improved.
In the vehicle body side portion structure of the present embodiment, since the bent flange portion 20r is bent toward the axial center O side of the rear wheel Wr, the dust-proof sealant s can be easily applied to the mating portion between the end portion of the inclined joint wall 20q and the end portion of the inclined wall 11O-c on the back side of the bent flange portion 20 r. That is, when the dust-proof sealing agent s is applied, the bent flange portion 20r can be used as a guide for applying the dust-proof sealing agent s, and the protrusion of the dust-proof sealing agent s from the end portion of the inclined wall 11O-c can be hidden by the bent flange portion 20 r.
In the vehicle body side portion structure of the present embodiment, since the garnish 60 covering the vehicle width direction outer side of the inclined joint wall 20q is attached to the side outer panel 15, the joint trace or the like on the inclined joint wall 20q can be covered by the garnish 60. Therefore, when the structure of the present embodiment is adopted, it is possible to improve the appearance as viewed from the outside, and to prevent the clothes of the occupant from swinging at the free end of the bent flange portion 20 r.
In the vehicle body side portion structure of the present embodiment, the rear edge portion of the rocker reinforcing member 50 is coupled to the front edge portion of the wheel house reinforcing member 14 by the fastening bolt 23, and the inclined flange portion 50q is joined to the inclined wall 11O-c and the inclined joint wall 20q in a state of being sandwiched between the inclined wall 11O-c and the inclined joint wall 20 q. Therefore, the front portion of the rear wheel house 11 is firmly joined to the rear portion of the rocker reinforcing member 50 at a plurality of locations. In addition, in the present structure, the reinforced closed cross section 22 formed by the wheel house reinforcing member 14 can be made continuous with the closed cross section of the rocker 10 with high rigidity. Therefore, when this structure is employed, the rigidity from the periphery of the rear wheel house to the rocker 10 can be efficiently improved.
The present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the scope of the invention.
