Description

[0001] The present invention relates to a vehicle body side structure, and more particularly to a vehicle body side structure adapted to mount a fender panel to a side splash guard via a fender bracket.

[0002] A vehicle body side structure is conventionally designed such that a fender panel is mounted to a side splash guard via a fender bracket.

[0003] In such a vehicle body side structure, when loads are applied from above near a boundary between an upper portion of the fender panel and a front hood, the fender panel absorbs the loads by deforming downward along the length of the vehicle. In this case, the loads are desirably absorbed safely with the shortest possible deformation distance in a vertical direction. Therefore, it is conceivable to design the fender bracket to be easily deformable by providing numerous fragile sections. However, the fender panel is an important exterior panel that determines the appearance of a motor vehicle's front end and must therefore be precisely fixed in place while maintaining the required rigidity.Furthermore, while the fender bracket is loaded, the loads are preferably absorbed equally stably at each point in time of a time series and it is desirable that the loads are absorbed without an exceptional peak-shaped load absorption.

[0004] For these reasons, traditional methods for load bearing include folding and deforming a fender bracket in a Z-shape in the front view of a vehicle body, or tilting and deforming a fender bracket. However, when the deformation progresses to a certain point, these methods result in buckling, which causes the deformation to progress more rapidly, resulting in a peak load bearing while the fender bracket is bearing load. Therefore, these methods have the problem of not being able to stably absorb loads while they are being applied.In such a case, it is conceivable to add additional components or improve the stiffness of the fender bracket itself to ensure consistent load bearing capacity. However, the stiffness must be balanced between an initial deformation phase and a later deformation phase of the fender bracket. The assembly stiffness of the fender bracket is therefore related to the deformability in the initial phase of deformation, and to ensure consistent load bearing capacity, the three types of stiffness must be balanced: the stiffness of the fender bracket itself, the stiffness in the initial phase of deformation, and the stiffness in the later deformation phase. However, balancing the stiffness between the initial and a later deformation phase of the fender bracket is generally associated with considerable difficulties.Furthermore, the above-mentioned method of folding the fender bracket into a Z-shape poses a concern that the fender bracket may deform and penetrate into the engine compartment. This poses a problem in that engine compartment components cannot be arranged within the deformation area of ​​the fender bracket, hindering the effective utilization of the engine compartment.

[0005] Document JP 2012-96735 A discloses a vehicle body side structure in which a fender panel is supported on a side splash guard via a fender bracket to absorb any load applied to the fender panel from above by deformation of the fender bracket. In the technique according to JP 2012-96735 A, upon deformation of the fender bracket, the upper part of the fender bracket bulges downward, and as a result, it is conceivable that the fender bracket and the side splash guard deform to be bent toward a vehicle interior. In such a case, engine compartment components may not be able to be arranged in deformation areas of the fender bracket and the side splash guard, hindering effective use of the engine compartment.

[0006] Document DE 10 2011 085 663 A1 concerns a fender extension and a body front assembly

[0007] Document JP 2007 - 296 883 A relates to a front structure of a vehicle body in which left and right upper members are provided with fender brackets and left and right fender brackets support the left and right front fenders.

[0008] The present invention has been made in view of the above circumstances and has an object to provide a vehicle body side structure which can cause a fender bracket loaded from above to receive loads with a sufficiently short deformation path, which can equally stably receive loads at any time point of a time series during the loading of the fender bracket, and which enables effective use of the engine compartment.

[0009] The present invention is defined in independent claim 1. The dependent claims define embodiments of the invention. Disclosed is a vehicle body side structure in which a fender panel is mounted to a side splash guard via a fender bracket, characterized in that the fender bracket includes a vertical wall which in turn includes a front surface and an inclined portion, the front surface extending along a body side surface, while the inclined portion extends rearward on the inner side of a vehicle body from a rear end of the front surface; at an upper end of the vertical wall, an upper flat portion is provided which extends to an inner side of the vehicle body; at a lower end of the vertical wall, a lower flat portion is provided;an elongated hole extending in a longitudinal direction of the vehicle is provided in an upper part of the vertical wall; the lower flat portion is attached to the side splash guard; an extension portion extending downward from an upper end of the fender panel is arranged at substantially the same position as the vertical wall in the vehicle transverse direction, and the extension portion is attached to the upper flat portion.

[0010] Furthermore, a length dimension from an upper edge of the elongated hole in the fender bracket to an upper longitudinal edge forming a boundary between the vertical wall and the upper flat portion is equal to or greater than a length dimension from an attachment of the fender panel to the upper flat portion of the fender bracket to the upper longitudinal edge; in a vicinity of a front or rear end of the upper longitudinal edge of the vertical wall, a first upper vertical edge portion or a second upper vertical edge portion is formed which extends downward from the upper flat portion along the vehicle body, and a lower end of the first upper vertical edge portion or the second upper vertical edge portion is configured to function as a bending point when the vertical wall bends under load.

[0011] Furthermore, the vertical wall of the fender bracket includes a rear surface extending rearward from a rear end of the inclined portion along the vehicle body, and the front surface is arranged outward of the rear surface with respect to the vehicle body.

[0012] In addition, a first bead and a second bead are provided below the elongated hole in the vertical wall of the fender bracket, the first bead extending in the longitudinal direction of the vehicle body from the front surface to the inclined portion and projecting to an inner side of the vehicle body, while the second bead extending in the longitudinal direction of the vehicle body from the inclined portion to the rear surface and projecting to the outer side of the vehicle body.

[0013] In addition, the vertical wall of the fender bracket has the shape of a parallelogram whose upper longitudinal edge is arranged forward of a lower longitudinal edge with respect to the vehicle body, the lower longitudinal edge forming a boundary between the vertical wall and the lower flat portion, and a rear end portion of the elongated hole, an upper end portion of the inclined portion and the fender panel attachment in the upper flat portion are superimposed on one another in the vicinity of the rear end of the upper longitudinal edge in side view.

[0014] As described above, there is disclosed a vehicle body side structure in which a fender panel is mounted to a side splash guard via a fender bracket, characterized in that the fender bracket includes a vertical wall including a front surface and an inclined portion, the front surface extending along a body side surface, while the inclined portion extends rearward on the inner side of a vehicle body from a rear end of the front surface; an upper flat portion is provided at an upper end of the vertical wall and extends toward an inner side of the vehicle body; a lower flat portion is provided at a lower end of the vertical wall; an elongated hole extending in a longitudinal direction of the vehicle is provided in an upper part of the vertical wall;The lower flat section is attached to the side splash guard; an extension section extending downward from an upper end of the fender panel is arranged at substantially the same position as the vertical wall in the vehicle transverse direction, and the extension section is attached to the upper flat section. When the fender panel is loaded from above, it pivots outward from the vehicle body. At the same time, the upper edge of the elongated hole in the fender bracket shifts toward the outside of the vehicle body relative to the lower edge, causing the fender bracket to collapse with the upper and lower edges overlapping. This allows the fender bracket to absorb loads with a sufficiently short deformation path, allows loads to be absorbed equally stably at any time during a time series during the loading of the fender bracket, and allows the engine compartment to be used effectively.

[0015] In the vehicle body side structure, a length from an upper edge of the elongated hole in the fender bracket to an upper longitudinal edge forming a boundary between the vertical wall and the upper flat portion is equal to or greater than a length from an attachment of the fender panel to the upper flat portion of the fender bracket to the upper longitudinal edge; in a vicinity of a front or rear end of the upper longitudinal edge of the vertical wall, a first upper vertical edge portion or a second upper vertical edge portion is formed, which extends downward from the upper flat portion along the vehicle body, and a lower end of the first upper vertical edge portion or the second upper vertical edge portion is configured to function as a bending point when the vertical wall bends under load.Consequently, the lower ends of the first upper vertical edge portion and the second upper vertical edge portion act as triggers (bending points) for the bending of the vertical wall and allow the fender bracket to collapse from the bending points.

[0016] In the vehicle body side structure, since the vertical wall of the fender bracket further includes a rear surface extending rearward from a rear end of the inclined portion along the vehicle body, and the front surface is disposed outward of the rear surface with respect to the vehicle body, the front surface and the inclined portion of the vertical wall form a step shape, whereby the fender panel attachment at the upper flat portion can be reliably swung out from the vehicle body and at the same time the rigidity of the vertical wall can be improved.

[0017] In the vehicle body side structure, a first bead and a second bead are provided below the elongated hole in the vertical wall of the fender bracket. The first bead extends in the longitudinal direction of the vehicle body from the front surface to the inclined portion and protrudes toward an inner side of the vehicle body, while the second bead extends in the longitudinal direction of the vehicle body from the inclined portion to the rear surface and protrudes toward an outer side of the vehicle body. Consequently, in the inclined portion, the step height of a longitudinal line of the vehicle body can be reduced and can be configured as a polygonal line on the vertical wall.This allows a bottom side of the vertical wall to be made to tilt towards the inside of the vehicle body when the fender bracket is loaded, and a control can be carried out to prevent the upper edge of the slot from hitting the lower edge when the upper edge sinks downward due to the buckling.

[0018] In the vehicle body side structure, since the vertical wall of the fender bracket has a parallelogram shape whose upper longitudinal edge is located forward of a lower longitudinal edge with respect to the vehicle body, the lower longitudinal edge forming a boundary between the vertical wall and the lower flat portion, and a rear end portion of the elongated hole, an upper end portion of the inclined portion, and the fender panel attachment in the upper flat portion are superimposed on each other in the vicinity of the rear end of the upper longitudinal edge in side view, loads can be effectively received and absorbed by the inclined portion between corresponding upper and lower corners of the parallelogram.

[0019] In the following, with reference to the Fig. 1 to 11, an embodiment of a vehicle body side structure according to the present invention will be described in detail.

[0020] As in the Fig. As shown in FIGS. 1 to 6, in a vehicle 1 according to the present embodiment, a fender panel 10 is mounted to a side splash guard 40 via a fender bracket 20. Here, the fender panel 10 includes an extension portion 11 extending downward from an upper end of the fender panel and a flange 12 extending from a lower end of the extension portion to an inner side of the vehicle body. The side splash guard 40 includes a flange 41 extending from an upper end of the side splash guard 40 to the inner side of the vehicle body.The fender bracket 20 includes a vertical wall 21 extending in a vertical direction of the vehicle body, an upper flat portion 22 at an upper end of the vertical wall extending toward an inner side of the vehicle body, and a lower flat portion 23 at a lower end of the vertical wall extending toward the outer side of the vehicle body. The fender bracket 20 is fixed with the lower flat portion 23 to the flange 41 of the side splash guard 40, and the flange 12 of the fender panel 10 is fixed to the upper flat portion 22. At the same time, the extension portion 11 of the fender panel 10 is arranged at substantially the same position in the vehicle transverse direction as the vertical wall 21 of the fender bracket 20.

[0021] The vertical wall 21 of the fender holder 20 is described below with reference to the Fig. 7 to 9 are described in detail.

[0022] The vertical wall 21 of the fender bracket 20 includes a front surface 24, an inclined portion 25, and a rear surface 26 in a longitudinal direction of the vehicle body. The front surface 24 extends along a body side surface, the inclined portion 25 extends rearward on the inner side of the vehicle body from a rear end of the front surface, the rear surface 26 extends rearward along the vehicle body from a rear end of the inclined portion, and the front surface 24 is located outward of the rear surface 26 with respect to the vehicle body. The inclined portion 25 extends substantially from the upper flat portion 22 in the vertical direction of the vehicle body to the lower flat portion 23.The vertical wall 21 has the shape of a parallelogram, the upper longitudinal edge 28 of which is arranged forward of a lower longitudinal edge 27 with respect to the vehicle body. The upper longitudinal edge 28 forms a boundary between the vertical wall and the upper flat portion 22, while the lower longitudinal edge 27 forms a boundary between the vertical wall and the lower flat portion 23. An elongated hole 29 extending in a longitudinal direction of the vehicle is provided in an upper part of the vertical wall 21. The fender bracket 20 is configured such that a rear end portion 29a of the elongated hole 29, an upper end portion 25a of the inclined portion 25, and a fender panel attachment (bolt through hole) 22a are superimposed on one another near a rear end of the upper longitudinal edge 28 in side view.If a length measurement from an upper edge 29b of the elongated hole 29 in the vertical wall 21 to the upper longitudinal edge 28 is marked with "A" and a length measurement from the fender panel attachment 22a of the upper flat section 22 to the upper longitudinal edge 28 is marked with "B" (see . Fig. 6), the length dimension A is set to be equal to or greater than the length dimension B. Furthermore, a first upper vertical edge portion 30 is formed near a front end of the upper longitudinal edge 28 of the vertical wall 21, and a second upper vertical edge portion 31 is formed near a rear end of the upper longitudinal edge 28 of the vertical wall 21, each extending downward along the vehicle body from the upper planar portion 22. A lower end 30a of the first upper vertical edge portion 30 or a lower end 31a of the second upper vertical edge portion 31 is located near a vertical position of the elongated hole 29 with respect to the vehicle body.On the fender bracket 20, a first bead 32 and a second bead 33 are provided approximately near the center of the vertical wall 21 in the vertical direction of the vehicle body, the first bead 32 extending in the longitudinal direction of the vehicle body from the front surface 24 to the inclined portion 25 and projecting toward the inside of the vehicle body, while the second bead 33 extending in the longitudinal direction of the vehicle body from the inclined portion to the rear surface 26 and projecting toward the outside of the vehicle body. Fig. 7 to 9, reference numeral 22b denotes a lamp mount disposed at the front of the upper planar portion 22 with respect to the vehicle body, and 34 and 35 denote wedge-shaped recesses formed on opposite sides of the lower longitudinal edge 27 and extending from the inclined portion 25 or the rear surface 26 to the lower planar portion 23.

[0023] A reinforcing member 42 is attached to the side splash guard 40, and the flange 41 of the side splash guard and the reinforcing member 42 form a closed cross section and thereby support the fender bracket 20 from below to prevent the fender bracket 20 from falling down as a whole.

[0024] The reference number 51 in the Fig. 1, Fig. 6 and Fig. 11 denotes a front hood; the reference number 52 in Fig. 1 denotes a headlight; the reference number 53 in Fig. 2 denotes a cowl panel and the reference number 54 in the Fig. 2, Fig. 5, Fig. 6 and Fig. 11 indicates an engine compartment.

[0025] Next, the operation of the present embodiment will be described.

[0026] According to the present embodiment, when loads are applied from above to the fender panel 10 or near an interface between the fender panel 10 and the front hood 51, the loads applied to the fender panel 10 are directly transmitted to the fender stay 20 because the extension portion 11 of the fender panel 10 and the vertical wall 21 of the fender stay 20 are arranged substantially in a straight line in the vertical direction of the vehicle body. At this time, a fracture-prone portion is formed near the elongated hole 29 in the vertical wall 21 of the fender stay 20, and the lower end 30a of the first upper vertical edge portion 30 or the lower end 31a of the second upper vertical edge portion 31 acts as an initiator (bending point) for the bending, allowing the fender stay 20 to collapse from the bending point.That is, if the vertical wall 21 has a portion near the fender bracket 20 that serves as a trigger for bending deformation, this portion will form a starting point, whereby bending can be reliably caused below the upper edge 29b of the elongated hole 29. As a result, both the extension portion 11 of the fender panel 10 and the vertical wall 21 of the fender bracket 20 begin to rotate in the direction of arrow C (see ). Fig.6). By pulling an upper surface of the upper flat portion 22 of the fender bracket 20 from the upper edge 29b of the elongated hole 29 in the fender bracket 20, it begins to face the outside of the vehicle body and pivots the fender panel mount 22a out of the vehicle body. As the fender panel mount 22a pivots out, the movement of the fender panel mount 22a toward the inside of the vehicle body is reduced. At the same time, the upper edge 29b of the elongated hole 29 in the fender bracket 20 shifts toward the outside of the vehicle body relative to a lower edge 29c of the elongated hole 29, and the fender bracket 20 further collapses, with the upper edge 29b and the lower edge 29c overlapping each other in a staggered state.In this way, according to the present embodiment, although the fender bracket 20 as a whole tilts slightly toward the inside of the vehicle body, the movement of the fender panel fastener 22a toward the inside of the vehicle body is reduced, and the fender bracket 20 collapses, with the fender panel fastener 22a performing an approximately downward movement. In this way, loads can be absorbed over a short deformation path without causing the fender bracket 20 to bulge sharply toward the inside of the vehicle body. Furthermore, loads can be absorbed equally stably at any time point in a time series during a deformation process in which the fender bracket 20 is loaded.It should be noted that a phenomenon in which the upper flat portion 22 rotates as explained above is more likely to occur with increasing length A from the upper edge 29b of the elongated hole 29 in the fender bracket 20 to the upper longitudinal edge 28, that is, to a certain extent with decreasing height of the upper edge 29b of the elongated hole 29. .

[0027] Furthermore, according to the present embodiment, since the front surface 24 is located outward of the rear surface 26 with respect to the vehicle body, a stepped shape is formed on the vertical wall 21 of the fender bracket 20 when viewed from below, thereby improving the static rigidity of the fender bracket 20 and thereby compensating for a reduction in rigidity caused by the elongated hole 29. At the same time, an outer edge 22c of the vehicle body near the fender panel attachment 22a of the upper flat portion 22 has a curved shape, thereby improving the rigidity around the fender panel attachment.According to the present embodiment, since the elongated hole 29 extends from the front surface 24 to the inclined portion 25, when the fender bracket 20 is loaded, a part above the elongated hole 29 shifts toward the outside of the vehicle body with respect to the lower part and causes the fender bracket 20 to collapse to form a shape convex toward the outside of the vehicle body.

[0028] Furthermore, according to the present embodiment, since the first bead 32 projecting toward the inside of the vehicle body and the second bead 33 projecting toward the outside of the vehicle body are provided on the vertical wall 21 of the fender bracket 20, the step height caused by the inclined portion 25 on the longitudinal line D of the vehicle body connecting approximately central portions of the first bead 32 and the second bead 33, respectively, can be reduced. Therefore, when the fender bracket 20 is loaded, the line D becomes a polygonal line, an inward inclination of the lower side portion of the vertical wall 21 and an inward displacement of the lower edge 29c of the elongated hole 29 can be caused, and thereby, control can be performed to prevent the upper edge 29b of the elongated hole 29 from colliding with the lower edge 29c when the upper edge 29b sinks downward due to buckling.

[0029] Furthermore, according to the present embodiment, the vertical wall 21 has the shape of a parallelogram, the upper longitudinal edge 28 of which is offset forward of a lower longitudinal edge 27 relative to the vehicle body. Furthermore, the rear end portion 29a of the elongated hole 29, the upper end portion 25a of the inclined portion 25, and a fender panel attachment 22a are superimposed on each other near the rear end of the upper longitudinal edge 28 in a side view, and the corresponding upper and lower corners of the parallelogram are connected to each other by the inclined portion 25 in the vertical direction of the vehicle body. Consequently, a load from above can be securely supported.Since many of the loads from the fender panel 10 act on the fender panel mount 22a, it is advantageous for the entire fender bracket 20 to design the vertical wall 21 as a parallelogram so that the loads are received primarily by the upper and lower corners of the parallelogram. The present embodiment is also advantageous in that the received loads are absorbed by deformation.

[0030] It should be noted that in the present embodiment, the recesses 34 and 35 in a lower part of the vertical wall 21 of the fender bracket 20 are adapted to form a starting point for deformation.

[0031] Although in the above-described embodiment, the vertical wall 21 is provided with the front surface 24, the inclined portion 25, and the rear surface 26 in the longitudinal direction of the vehicle body, the present invention is not limited to this, and it suffices to provide at least the front surface and the inclined portion. Such a configuration can also provide advantageous effects similar to those of the above-described present embodiment.

[0032] Furthermore, although in the above embodiment, the first bead 32 and the second bead 33 are arranged approximately near the center—in the vertical direction of the vehicle body—of the vertical wall 21 of the fender bracket 20, the present invention is not limited thereto. That is, the first bead 32 and the second bead 33 need not be arranged approximately near the center—in the vertical direction of the vehicle body—of the vertical wall 21 and, in short, can be arranged at any convenient location below the elongated hole 29. 1 vehicle 10 fender panel 11 Extension section 12 Flange 20 fender brackets 21 Vertical wall 22 Upper level section 22a Fender panel attachment 22b Lamp attachment 22c Vehicle body outer circumference 23 Lower level section 24 Front surface 25 Inclined section 25a Upper end section 26 Rear surface 27 Lower longitudinal edge 28 Upper longitudinal edge 29 slot 29a Rear end section 29b Upper edge 29c Lower margin 30 First upper vertical edge section 30a Lower End 31 Second upper vertical edge section 31a Lower end 32 First bead 33 Second bead 34, 35 Deepening 40 Side splash guard 41 Flange 42 Reinforcing element 51 Front hood 52 headlights 53 cowl panel 54 Engine compartment
