Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, the side trim is often a thin - plate - shaped resin molded product. And, a support portion (the aforementioned slide rail in Patent Document 1) which is a portion of the side trim for supporting the luggage board is often formed in a bulged - out plate shape having generally the same thickness (plate thickness) from the viewpoint of preventing sink marks during molding. In this case, there is a problem that due to the load of luggage or the like loaded on the luggage board, the support portion in the side trim may bend in the vertical direction, and the support of the luggage board may become unstable.

[0006] The present invention was made to solve the above problems, and its objective is to provide a vehicle body side structure that has a structure capable of stably supporting a luggage board. [Means for solving the problem]

[0007] The vehicle interior side structure according to the present invention for achieving the above objective includes a vehicle body side and a resin molded side trim attached to the vehicle body side from the inside in the vehicle width direction and constituting the side wall of the vehicle interior. The side trim has a plurality of support parts that are spaced apart from each other in the vehicle vertical direction and each supports the outer edge in the vehicle width direction of a luggage board that is arranged in a transverse position in the vehicle interior. Each of the plurality of support parts has a mounting wall that protrudes inward in the vehicle width direction from a reference wall including a predetermined reference plane on the inner surface of the side trim in the vehicle width direction and on which the outer edge in the vehicle width direction is placed, and is formed to bulge inward in the vehicle width direction relative to the reference plane. The plurality of support parts include a plurality of target support parts as part of the plurality of support parts. Each of the plurality of target support parts has a connecting wall that extends downward from the inner end in the vehicle width direction of the mounting wall described above and connects to the reference wall, and is connected to the vehicle body side in a base end region including the base end of the connecting wall in the side trim. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a vehicle body side structure that can stably support a luggage board even when multiple support parts for supporting the luggage board at multiple height positions are formed in the shape of bulging plates. [Brief explanation of the drawing]

[Figure 8] This diagram illustrates a modified example of a reinforcing member. [Modes for carrying out the invention]

[0010] Hereinafter, embodiments of the vehicle body side structure according to the present invention will be described with reference to the drawings.

[0011] Figure 1 is an exploded perspective view of a vehicle body side structure according to one embodiment of the present invention. In the figure, arrow F indicates the front of the vehicle in the longitudinal direction, and arrow B indicates the rear of the vehicle in the longitudinal direction. Arrows R and L indicate the right and left sides in the vehicle width direction when an occupant is looking forward. Arrow U indicates the top of the vehicle in the vertical direction.

[0012] The vehicle body side structure of this embodiment is applicable to vehicles in which the rear of the passenger compartment (i.e., the rear area of ​​the passenger compartment) is mainly used as a cargo compartment (luggage storage space) S. Occupants of the vehicle can access the passenger compartment through the front side door opening (not shown) which is opened and closed by the front side door (not shown), the rear side door opening D1 which is opened and closed by the rear side door (not shown), and the back door opening D2 which is opened and closed by the back door (not shown). In the passenger compartment of the vehicle, for example, front seats and rear seats are arranged (not shown), and when the rear seats are upright, the area of ​​the passenger compartment behind the seatbacks of the rear seats can be used as a cargo compartment S.

[0013] Referring to Figure 1, the vehicle body side structure of this embodiment has a structure that allows the luggage board LB to be supported vertically within the cargo compartment S in a transverse position (i.e., in a position extending in the vehicle width direction and the vehicle longitudinal direction), and at multiple (multiple levels) of height positions. The luggage board LB is a flat plate member that is placed in the cargo compartment S and can divide and separate the cargo compartment S vertically. The luggage board LB is formed, for example, in a roughly rectangular shape in plan view.

[0014] The vehicle body side structure of this embodiment includes a side trim 1 that constitutes the side wall of the rear region (cargo area S) of the vehicle's passenger compartment, a vehicle body side 10 that constitutes the side of the vehicle body, a reinforcing member 20, and a cushioning member 30. The vehicle body side 10 is the rear portion of the side of the vehicle body (a structural part located in the portion corresponding to the cargo area S), and will be referred to as the quarter panel 10 from now on. The side trim 1 is attached to the quarter panel 10 from the inside in the vehicle width direction, and the reinforcing member 20 and the cushioning member 30 are arranged between the side trim 1 and the quarter panel 10.

[0015] The side trim 1, quarter panel 10, reinforcing member 20, and cushion member 30 are provided on both sides in the vehicle width direction of the floor portion (not shown) at the rear part of the passenger compartment. In FIG. 1, the elements (1, 10, 20, 30) on the right side are shown, and the elements (1, 10, 20, 30) on the left side have the same shape as the shape described in detail below, except that they are symmetric with respect to the elements (1, 10, 20, 30) on the right side in the vehicle width direction. In FIGS. 2 to 7 described later, the elements on the right side are shown.

[0016] The side trim 1 is the rear part of the side wall of the vehicle body and constitutes the end wall in the vehicle width direction of the luggage compartment S. The side trim 1 is also called the luggage compartment side wall or rear side trim. In other words, the side trim 1 constitutes the design surface facing the luggage compartment S.

[0017] The side trim 1 is, for example, a resin molded product having a bulging shape. Most of the side trim 1 has substantially the same thickness (plate thickness). The lower region of the side trim 1 bulges greatly inward in the vehicle width direction corresponding to the wheelhouse 11 (not shown) of the quarter panel (side part of the vehicle body) 10 described later. The front edge of the side trim 1 forms the opening rear edge of the rear side door opening D1. The front edge of the side trim 1 extends along the front edge portion of the quarter panel 10 and is attached to the quarter panel 10.

[0018] In the present embodiment, a trim that forms the opening side edge and opening lower edge of the back door opening D2 is integrally formed at the rear part of the side trim 1. The edge of the trim at the rear part of the side trim 1 extends along the edge of the panel part integrally formed at the rear part of the quarter panel 10 and is attached to the quarter panel 10.

[0019] The quarter panel 10 is the rear part of the side of the vehicle body as described above. The quarter panel 10 is mainly made of a metal plate material and is formed by press-forming or the like. The front edge of the quarter panel 10 is formed with high rigidity and forms the opening rear edge of the rear side door opening D1 together with the front edge of the side trim 1. The edge of the panel part at the rear of the quarter panel 10 is also formed with high rigidity and forms the opening side edge and the opening lower edge of the back door opening D2 together with the edge of the trim at the rear of the side trim 1.

[0020] In the lower region of the quarter panel 10, a wheelhouse 11 that covers the rear wheel from above, a strut tower support portion 12 for the rear suspension, and the like are provided. Most of the lower portion of the quarter panel 10 is formed so as to bulge greatly inward in the vehicle width direction.

[0021] The reinforcing member 20 is formed by appropriately bending a metal plate material and is a member for reinforcing the quarter panel 10. The reinforcing member 20 has a reinforcing main body portion 20a for reinforcing the quarter panel 10. The reinforcing main body portion 20a extends generally in the vehicle front-rear direction. The front end portion of the reinforcing main body portion 20a is fixed to the front edge of the quarter panel 10, and the rear end portion of the reinforcing main body portion 20a is fixed to the edge of the panel portion at the rear of the quarter panel 10. The reinforcing main body portion 20a extends so as to span between the front edge of the quarter panel 10 and the portion forming the opening edge of the back door opening D2 in the quarter panel 10. Details of the shape of the reinforcing member 20 and the like will be described later.

[0022] The cushion member 30 is provided so as to be sandwiched between the lower portion of the quarter panel 10 and the lower portion of the side trim 1, and is made of a foamed material such as foamed propylene. Vibrations that may be transmitted from the wheelhouse 11 side during driving are absorbed by the cushion member 30, and the transmission of vibrations to the side trim 1 is suppressed. The cushion member 30 is formed to fit from the outside in the vehicle width direction into the lower portion of the side trim 1 that bulges inward in the vehicle width direction. The side surface of the cushion member 30 facing the quarter panel 10 is formed to match the bulging shape of the lower portion of the quarter panel 10 (a curved shape such as the inner panel of the wheelhouse 11) (see Figures 3 to 6 below). The cushion member 30 is also connected to the side trim 1 or the quarter panel 10. Referring to Figure 1, a connecting portion 31 is provided on the upper surface of the cushion member 30. The connecting portion 31 may be molded integrally with the cushion member 30, or it may be attached to the molded cushion member 30 as a separate component. Furthermore, a connecting seat portion 32 is provided on the surface of the cushion member 30 that faces the side trim 1. The seat portion 32 may be molded integrally with the cushion member 30, or it may be attached to the molded cushion member 30 as a separate component.

[0023] Figure 2 is a plan view of the assembly 50, consisting of the side trim 1, reinforcing member 20, and cushioning member 30, as seen from inside the cargo compartment S, after it has been removed from the quarter panel 10. Referring to Figure 2, the side trim 1 is provided with multiple support parts (2A, 2B, 2C) for supporting the luggage board LB in a transverse position within the cargo compartment S and at multiple (multiple) height positions vertically. In other words, the side trim 1 has multiple support parts (2A, 2B, 2C) that are spaced apart from each other in the vertical direction of the vehicle and each support the outer edge LB0 of the luggage board LB, which is the outer edge in the vehicle width direction of the luggage board LB that is positioned transversely in the passenger compartment (cargo compartment S). In the following explanation, we will use the case where the support parts are provided in three stages vertically as an example, but any three or more stages of support parts are acceptable.

[0024] Each support portion (2A, 2B, 2C) constitutes a part of the side trim 1. Each support portion (2A, 2B, 2C) as a whole is formed to bulge inward in the vehicle width direction relative to a predetermined reference surface 1a1 on the inner surface of the side trim 1 in the vehicle width direction (i.e., the design surface facing the passenger compartment). In other words, each support portion (2A, 2B, 2C) is formed in a bulging plate shape with roughly the same thickness (plate thickness) from the viewpoint of preventing shrinkage during molding. When viewed from the passenger compartment side, each support portion (2A, 2B, 2C) protrudes inward in the vehicle width direction relative to the reference surface 1a1. The predetermined reference surface 1a1 of the side trim 1 is, for example, a flat surface set on the upper side in the vehicle vertical direction and the front side in the vehicle longitudinal direction, facing the passenger compartment (cargo compartment S).

[0025] Each support section (2A, 2B, 2C) is formed in continuity with the reference wall 1a, which includes the reference surface 1a1 in the side trim 1 (in other words, the region in which the reference surface 1a1 is set). Each support section (2A, 2B, 2C) has a thickness (plate thickness) that is approximately the same as the thickness (plate thickness) of the reference wall 1a of the side trim 1.

[0026] Each support section (2A, 2B, 2C) has a mounting wall 3 that protrudes inward in the vehicle width direction from the reference wall 1a and on which the outer edge LB0 of the luggage board LB is placed. The mounting wall 3 extends in the vehicle longitudinal direction and inward in the vehicle width direction. Each support section (2A, 2B, 2C) is formed over approximately the entire length of the side trim 1 in the vehicle longitudinal direction. The luggage board LB can be placed on a mounting wall 3 at any level (height position) and supported within the cargo compartment S. Although not particularly limited, a positioning section 4 for positioning the board is formed on the upper surface of each mounting wall 3, which fits into a recess (not shown) formed in the outer edge LB0 of the board. The positioning section 4 is formed to bulge out in a rectangular shape when viewed from the inside in the vehicle width direction. The parts of each mounting wall 3 other than the positioning section 4 are formed flat.

[0027] In this embodiment, the multiple support parts (2A, 2B, 2C) are divided into the lowest support part (2C), which is the support part located at the bottom, and the remaining multiple (in this case, two) target support parts (2A, 2B). In other words, the multiple support parts (2A, 2B, 2C) include the multiple target support parts (2A, 2B) as part of the multiple support parts (2A, 2B, 2C). The multiple support parts (2A, 2B, 2C) are then divided into the multiple target support parts (2A, 2B) and the lowest support part located at the bottom. Hereafter, when distinguishing between the multiple support parts (2A, 2B, 2C), the upper target support part (2A) will be called the first support part 2A, the lower target support part (2B) will be called the second support part 2B, and the lowest support part (2C) will be called the third support part 2C.

[0028] Incidentally, as mentioned above, each support portion (2A, 2B, 2C) of the side trim 1 is formed in a bulging plate shape with roughly the same thickness (plate thickness). Therefore, if left as is, the load of luggage etc. placed on the luggage board LB may cause each support portion (2A, 2B, 2C) to bend in the vertical direction, potentially making the support of the luggage board LB unstable. In response to this, the vehicle body side structure according to this embodiment has the following structure (stable support structure) in order to stabilize the support of the luggage board LB.

[0029] Next, the stable support structure will be described in detail with reference to Figures 1 to 7. Figures 3 to 7 are diagrams illustrating the assembly 50 of the side trim 1, reinforcing member 20, and cushioning member 30. Figure 3 is a plan view seen from the outside in the vehicle width direction, Figure 4 is a cross-sectional view at the position of line AA shown in Figure 2, Figure 5 is a cross-sectional view at the position of line BB shown in Figure 2, Figure 6 is a cutaway model diagram at the position of line BB shown in Figure 2, and Figure 7 is a cutaway model diagram at the position of line CC shown in Figure 2. Note that in Figure 6, the reinforcing member 20 has been removed.

[0030] Referring to Figures 1 and 3, the reinforcing member 20 in this embodiment includes a plurality of front and rear connecting parts (21, 22), a plurality of upper and lower connecting parts (23, 24), and a connecting part 25 for protruding parts. The plurality of front and rear connecting parts (21, 22) are spaced apart from each other in the vehicle's vertical direction, and the plurality of upper and lower connecting parts (23, 24) and the connecting part 25 for protruding parts are spaced apart from each other in the vehicle's longitudinal direction. Each front and rear connecting part (21, 22) extends in the vehicle's longitudinal direction, and each upper and lower connecting part (23, 24) and the connecting part 25 for protruding parts extends in the vehicle's vertical direction. The number of front and rear connecting parts (21, 22) is the same as the number of target support parts (2A, 2B), which is 2 in this case. The number of upper and lower connecting parts (23, 24) can be set arbitrarily, and is 2 in this case.

[0031] The upper ends of each upper and lower connecting section (23, 24) and the connecting section 25 for the protruding section are fixed to the upper front and rear connecting section (21) from the outside in the vehicle width direction, and the lower ends of each upper and lower connecting section (23, 24) and the connecting section 25 for the protruding section are fixed to the lower front and rear connecting section (22) from the outside in the vehicle width direction, and the connecting sections (23, 24, 25) that extend vertically span between the upper and lower front and rear connecting sections (21, 22).

[0032] In this embodiment, the upper front-to-rear connecting portion (21) consists of the reinforcing main body portion 20a of the reinforcing member 20. That is, the upper front-to-rear connecting portion (21) is directly fixed to the quarter panel 10. The elements of the reinforcing member 20 other than the upper front-to-rear connecting portion (21) (22, 23, 24, 25) are indirectly fixed to the quarter panel 10 via the upper front-to-rear connecting portion (21). In the following, when distinguishing between each of the front-to-rear connecting portions (21, 22) and each of the upper-to-lower connecting portions (23, 24), the upper front-to-rear connecting portion (21) will be referred to as the first front-to-rear connecting portion 21 or the reinforcing main body portion 20a, the lower front-to-rear connecting portion (22) as the second front-to-rear connecting portion 22, the front upper-to-lower connecting portion (23) as the first upper-to-lower connecting portion 23, and the rear upper-to-lower connecting portion (24) as the second upper-to-lower connecting portion 24. The detailed shapes of each element of the reinforcing member 20 will be described later.

[0033] Referring to Figures 4 to 7, each of the target support sections (2A, 2B) has the aforementioned mounting wall 3 and a connecting wall 5 that extends downward from the inner end of the mounting wall 3 in the vehicle width direction and connects to the reference wall 1a, and as a whole, it bulges outward toward the cargo compartment S. Each mounting wall 3 protrudes inward in the vehicle width direction from the reference wall 1a, and most of its portion (the portion other than the positioning section 4) is formed flat. In each target support section (2A, 2B), the connecting wall 5 extends from the inner end of the mounting wall 3 in the vehicle width direction to the reference wall 1a below the mounting wall 3. That is, the tip of the connecting wall 5 is connected to the inner end (tip) of the mounting wall 3 in the vehicle width direction, and the base end of the connecting wall 5 is connected to the reference wall 1a. Specifically, the connecting wall 5 consists of, for example, a tip wall portion 5a that extends downward from the tip of the mounting wall 3 and an inclined wall portion 5b that extends from the lower end of the tip wall portion 5a to the reference wall 1a. The tip of the connecting wall 5 is the upper end of the tip wall portion 5a, and the base of the connecting wall 5 is the lower end of the inclined wall portion 5b.

[0034] In this embodiment, the side trim 1 has connecting walls (6a, 6b) facing the passenger compartment (cargo compartment S) that connect the mounting walls 3 of the multiple support parts (2A, 2B, 2C) in one end region in the front-rear direction of the vehicle. In the side trim 1 provided with three support parts (2A, 2B, 2C), there is a connecting wall 6a that connects the mounting wall 3 of the first support part 2A to the mounting wall 3 of the second support part 2B, and a connecting wall 6b that connects the mounting wall 3 of the second support part 2B to the mounting wall 3 of the third support part 2C.

[0035] Each connecting wall (6a, 6b) has a flat surface extending in the vehicle's longitudinal and vertical directions, and this flat surface is generally parallel to the reference surface 1a1 and faces the cargo compartment S. In this embodiment, the connecting walls (6a, 6b) are provided in the rear end region of the side trim 1 in the vehicle's longitudinal direction. Although not particularly limited, each connecting wall (6a, 6b) is located inward in the vehicle width direction relative to the reference wall 1a, and the portion of the side trim 1 including each connecting wall (6a, 6b) bulges inward in the vehicle width direction compared to the reference wall 1a. In this embodiment, the rear end of the luggage board LB can abut against the front end edge of each connecting wall (6a, 6b). Therefore, each connecting wall (6a, 6b) also functions as a movement restricting part that restricts the movement of the luggage board LB in the vehicle's longitudinal direction. Furthermore, the upper connecting wall 6a extends upward from the mounting wall 3 of the first support part 2A. The front edge of the extended portion 6a1 of the upper connecting wall 6a abuts against the rear end of the luggage board LB, which is placed on the mounting wall 3 of the first support portion 2A. Therefore, the extended portion 6a1 of the upper connecting wall 6a also functions as the movement restricting portion.

[0036] Here, the front and rear edges of the side trim 1 extend along the edges of the quarter panel 10 and are fixed to the quarter panel 10 by appropriate fasteners (e.g., clips). Most of the side trim 1 is generally spaced apart from the quarter panel 10. When the luggage board LB is placed on the upper surface of the mounting wall 3, the load of the luggage board LB makes the base end region V, which includes the connection area between the base end of the lower connecting wall 5 of the mounting wall 3 and the reference wall 1a, prone to becoming the starting point of deformation in the thin plate-like side trim 1.

[0037] In contrast, in this embodiment, each target support portion (2A, 2B) is connected to the quarter panel 10 in a base end region V that includes the base end of the connecting wall 5 in the side trim 1. In other words, this base end region V is the portion of the side trim 1 where the connecting wall 5 (inclined wall portion 5b) and the reference wall 1a intersect, and the region adjacent to that intersection. Referring to Figure 2, the base end region V specifically includes the portion where the lower roots of each target support portion (2A, 2B) in the reference wall 1a are connected, and is a band-shaped area that has a predetermined width in the vertical direction of the vehicle and extends in the longitudinal direction of the vehicle. In this way, the portion of the side trim 1 that is prone to deformation (base end region V) is connected to the quarter panel 10 (in other words, it is supported by the structural portion on the quarter panel side).

[0038] In this embodiment, each target support portion (2A, 2B) is connected to the quarter panel 10 by being connected to the quarter panel 10 via a reinforcing member 20 at the base end region V. Below, the detailed structure of the connection between the target support portions (2A, 2B) and the quarter panel 10 via the reinforcing member 20 will be described.

[0039] The side trim 1 has a plurality of bulging portions 7, a plurality of housing portions 8, a housing portion 8' separate from the housing portions 8, and a plurality of protruding portions 9. Each of these elements (7, 8, 8', 9) constitutes a part of the side trim 1 and serves as a connection point to the quarter panel 10 via the reinforcing member 20 (in other words, it serves as a contact point with the structural member on the quarter panel side or a support point by the structural member on the quarter panel side).

[0040] In this embodiment, the multiple bulging portions 7 bulge outward in the vehicle width direction in the base end region V and are spaced apart from each other in the vehicle's vertical direction. In this embodiment, the bulging portions 7 are provided at multiple locations in the base end region V corresponding to the multiple target support portions (2A, 2B) that are spaced apart in the vehicle's longitudinal direction. In other words, the bulging portions 7 are provided for each base end region V and are provided in two stages in the vertical direction. Although not particularly limited, the bulging portions 7 are provided at two locations in the front and rear for each base end region V, and the side trim 1 has a total of four bulging portions 7. Specifically, two bulging portions 7 are provided in the base end region V of the first support portion 2A, and two bulging portions 7 are provided in the base end region V of the second support portion 2B (see Figures 2, 3, and 6, etc.).

[0041] In this embodiment, each bulge 7 has an upwardly convex arc cross-sectional shape. Specifically, each bulge 7 extends in a direction intersecting the direction of the inclined surface of the inclined wall portion 5b of each target support portion (2A, 2B) (outward in the vehicle width direction). When viewed from the outside in the vehicle width direction of the side trim 1, each bulge 7 bulges outward along the surface of the inclined wall portion 5b. Each bulge 7 protrudes outward in the vehicle width direction relative to the reference wall 1a. The outer bulge 7a of this bulge 7, which protrudes outward in the vehicle width direction relative to the reference wall 1a, has a bottom portion 7a1 and is formed in a tapered cylindrical shape that decreases in diameter towards the outside in the vehicle width direction.

[0042] The housing section 8 is located in a region that overlaps with the region corresponding to the upper and lower connecting section (here, the first upper and lower connecting section 23) of the reference wall 1a when viewed from the outside in the vehicle width direction, and is the part that houses the vibration absorbing member G (see Figure 5). The housing section 8 is located in the region between the multiple support sections (2A, 2B, 2C) of the reference wall 1a. That is, it is located in the region between the first support section 2A and the second support section 2B, and in the region between the second support section 2B and the third support section 2C. In this embodiment, a separate housing section 8' is provided in the region above the first support section 2A. The vibration absorbing member G is also housed in this housing section 8', but the housing section 8' does not overlap with any of the upper and lower connecting sections (23, 24) (see Figure 3, etc.), and is distinguished from housing section 8. Each housing section 8 and housing section 8' bulges outward in the vehicle width direction from the reference wall 1a. The housing section 8 and housing section 8' are formed in a tapered cylindrical shape, for example, having bottom sections 8a and 8'a, and decreasing in diameter towards the outside in the vehicle width direction.

[0043] The vibration absorbing member G is made of an elastic material such as rubber. The vibration absorbing member G is housed in the housing 8 or housing 8' from the inside in the vehicle width direction and is formed in an outer shape that matches the bulging shape of the corresponding housing 8 or housing 8'. Referring to Figure 5, the inner end of the vibration absorbing member G in the vehicle width direction when housed protrudes inward in the vehicle width direction from the reference surface 1a1 and is in contact with the outer edge LB0 of the luggage board LB.

[0044] The protruding portion 9 is provided on each connecting wall (6a, 6b) and is a portion that bulges outward in the vehicle width direction. The protruding portion 9 is formed in a tapered cylindrical shape, for example, having a bottom portion 9a and decreasing in diameter towards the outward direction in the vehicle width direction. The upper protruding portion 9 is located at approximately the same height as the two bulging portions 7 that are spaced apart from each other in the front-rear direction, directly below the first support portion 2A. The lower protruding portion 9 is located at approximately the same height as the two bulging portions 7 that are spaced apart from each other in the front-rear direction, directly below the second support portion 2B.

[0045] The protruding portion 9 is located in a region that overlaps with the region corresponding to the front and rear connecting portions (21, 22) of the side trim 1 when viewed from the outside in the vehicle width direction. Specifically, the upper protruding portion 9 overlaps with the rear portion of the first front and rear connecting portion 21, and the lower protruding portion 9 overlaps with the rear end of the second front and rear connecting portion 22 (see Figure 3, etc.).

[0046] Next, the shape of each element of the reinforcing member 20, and the connection relationship between each of the above elements (7, 8, 8', 9) of the side trim 1 and the quarter panel 10 (reinforcing member 20) will be described in detail with reference to Figures 1, 3 to 5, and 7.

[0047] The first front-rear connecting section 21 (reinforcement body section 20a) extends generally in the front-rear direction of the vehicle. The first front-rear connecting section 21 bends outward in the vehicle width direction at a first bend section 21a located in the middle of its longitudinal direction, and then extends generally towards the front of the vehicle. First flange sections 21b for fixing to the quarter panel 10 are formed at both ends of the first front-rear connecting section 21. The upper part of the portion of the first front-rear connecting section 21 in front of the first bend section 21a bulges outward in the vehicle width direction, and the front first flange section 21b is provided at the end of this bulging portion. Both edges of the first front-rear connecting section 21 in the width direction (vehicle vertical direction) are bent inward in the vehicle width direction.

[0048] When viewed from one side in the vehicle width direction, the second front and rear connecting section 22 has a predetermined width and extends linearly in the vehicle's front-rear direction. When viewed from one side in the vehicle's vertical direction, the second front and rear connecting section 22 bends outward in the vehicle width direction at a second bend 22a located in the middle of its longitudinal direction, and then extends generally towards the front of the vehicle. Both edges of the second front and rear connecting section 22 in the width direction (vehicle vertical direction) are bent inward in the vehicle width direction.

[0049] The first upper and lower connecting portion 23 extends linearly in the vertical direction of the vehicle when viewed from one side in the vehicle width direction. When viewed from one side in the vehicle front and rear direction, the first upper and lower connecting portion 23 consists of a main body portion 23a that is roughly hat-shaped and protrudes outward in the vehicle width direction, and an L-shaped flange portion 23b that extends from the lower end of the main body portion 23a. The upper end of the main body portion 23a is fixed to the lower region of the front part of the first front and rear connecting portion 21, and the lower end of the main body portion 23a is fixed to the front part of the second front and rear connecting portion 22. The L-shaped flange portion 23b extends outward in the vehicle width direction from the lower end of the main body portion 23a, and then extends downward in the vehicle vertical direction. The L-shaped flange portion 23b protrudes downward relative to the second front and rear connecting portion 22 in the vehicle vertical direction. Both edges of the first upper and lower connecting portion 23 in the width direction (vehicle front and rear direction) are bent outward in the vehicle width direction.

[0050] The second upper and lower connecting portion 24 and the connecting portion for the protruding portion 25 extend linearly in the vertical direction of the vehicle, and both edges of these (24, 25) in the width direction (vehicle front-rear direction) are bent outward in the vehicle width direction. The upper end of the second upper and lower connecting portion 24 is fixed to the lower region of the front portion of the first front-rear connecting portion 21 behind the first upper and lower connecting portion 23, and the lower end of the second upper and lower connecting portion 24 is fixed to the front portion of the second front-rear connecting portion 22 behind the first upper and lower connecting portion 23. The upper end of the connecting portion for the protruding portion 25 is fixed to the portion of the first front-rear connecting portion 211 between the first bent portion 21a and the rear first flange portion 21b, and the lower end of the connecting portion for the protruding portion 25 is fixed to the rear end of the second front-rear connecting portion 22.

[0051] In this embodiment, the upper and lower connecting sections (23, 24) connect multiple target support sections (2A, 2B). In this embodiment, the upper and lower connecting sections (23, 24) connect multiple target support sections (2A, 2B) by connecting multiple bulging sections 7 in the vertical direction of the vehicle. Specifically, the two bulging sections 7 arranged vertically at the front are provided in an area that overlaps with the area corresponding to the first upper and lower connecting section 23 of the reference wall 1a, and the two bulging sections 7 arranged vertically at the rear are provided in an area that overlaps with the area corresponding to the second upper and lower connecting section 24 of the reference wall 1a. The upper bulging section 7 is connected to the quarter panel 10 via the upper and lower connecting sections (23, 24) and the first front and rear connecting section 21 (reinforcement main body section 20a), with the first front and rear connecting section 21 sandwiched between the bottom section 7a1 and each upper and lower connecting section (23, 24). The lower bulge portion 7 has its bottom portion 7a1 connected to the second front-rear connecting portion 22, and is connected to the quarter panel 10 via the second front-rear connecting portion 22, the upper and lower connecting portions (23, 24), and the first front-rear connecting portion 21 (reinforcement main body portion 20a).

[0052] In this embodiment, the connecting portion 25 for the protruding portion also connects multiple target support portions (2A, 2B) to each other. In this embodiment, the connecting portion 25 for the protruding portion connects multiple target support portions (2A, 2B) to each other by connecting multiple protruding portions 9 in the vertical direction of the vehicle. Specifically, the two vertically aligned protruding portions 9 are provided in the area of ​​the reference wall 1a that overlaps with the area corresponding to the connecting portion 25 for the protruding portion. The upper protruding portion 9 is connected to the quarter panel 10 via the connecting portion 25 for the protruding portion and the first front / rear connecting portion 21 (reinforcement body portion 20a), with the first front / rear connecting portion 21 sandwiched between the bottom portion 9a and the connecting portion 25 for the protruding portion. The lower protruding portion 9 has its bottom portion 9a connected to the second front / rear connecting portion 22, and is connected to the quarter panel 10 via the second front / rear connecting portion 22, the connecting portion 25 for the protruding portion, and the first front / rear connecting portion 21 (reinforcement body portion 20a).

[0053] In this embodiment, the upper and lower connecting portion (here, the first upper and lower connecting portion 23) that overlaps with the area of ​​the housing portion 8 is also connected to each housing portion 8. Specifically, the upper and lower intermediate portion of the first upper and lower connecting portion 23 (the protruding portion of the hat-shaped main body portion 23a) is connected to the bottom portion 8a of the upper housing portion 8, and the lower end portion (L-shaped flange portion 23b) of the first upper and lower connecting portion 23 is connected to the bottom portion 8a of the lower housing portion 8. In addition, the housing portion 8' is connected to the portion that bulges outward in the vehicle width direction on the front side of the first front and rear connecting portion 21.

[0054] In this embodiment, multiple target support parts (2A, 2B), namely the first support part 2A and the second support part 2B, are connected to the quarter panel 10 (reinforcement member 20) at the bulging part 7 of the base end region V.

[0055] In this embodiment, multiple (in this case, two) bulging portions 7 that are spaced apart from each other in the front-rear direction are connected to front-rear connecting portions (21, 22). Specifically, the upper front-rear bulging portions 7 are connected to the first front-rear connecting portion 21 (reinforcement main body portion 20a), and the lower front-rear bulging portions 7 are connected to the second front-rear connecting portion 22. In other words, the reinforcement member 20 has front-rear connecting portions (21, 22) that connect the multiple bulging portions 7 to each other in each base end region V.

[0056] In this embodiment, each front and rear connecting portion (21, 22) is also connected to a protruding portion 9. Specifically, the upper protruding portion 9 is connected to the portion between the first flange portion 21b and the first bent portion 21a on the rear side of the first front and rear connecting portion 21 (reinforcement body portion 20a), and the lower protruding portion 9 is connected to the rear end of the second front and rear connecting portion 22.

[0057] In this embodiment, the wheelhouse 11 of the quarter panel 10 is located below the mounting wall 3 of the lowest support portion 2C (third support portion 2C). The lowest support portion 2C is supported by the wheelhouse 11 via a cushion member 30 placed between its own mounting wall 3 and the wheelhouse 11.

[0058] As described above, in the vehicle body side structure according to this embodiment, each target support portion (2A, 2B) has a connecting wall 5 that extends downward from the inner end in the vehicle width direction of the mounting wall 3 and connects to the reference wall 1a, and is connected to the quarter panel 10 in the base end region V, which includes the base end of the connecting wall 5 in the side trim 1. This suppresses deformation such as the target support portions (2A, 2B) bending in the vertical direction starting from the base end region V. As a result, even when multiple target support portions (2A, 2B) for supporting the luggage board at multiple height positions are formed in a bulging plate shape, a vehicle body side structure is provided that can stably support the luggage board LB.

[0059] In this embodiment, each target support (2A, 2B) is connected to the quarter panel 10 via a reinforcing member 20 at the base end region V. This makes it easy to adjust the fixing position and other aspects with respect to the quarter panel 10. In addition, multiple target support (2A, 2B) are connected to each other by upper and lower connecting parts (23, 24). As a result, for example, if the target support (2A, 2B) is in two stages vertically, the load transmitted to one target support (2A or 2B) supporting the luggage board LB is also received by the other target support (2B or 2A), and deformation originating from the base end region V is effectively suppressed.

[0060] In this embodiment, the upper and lower connecting portions (23, 24) connect multiple bulging portions 7 to each other in the vertical direction of the vehicle, thereby connecting multiple target support portions (2A, 2B). As a result, the three-dimensional bulging portions 7 improve the support rigidity of the target support portions (2A, 2B) in the vertical direction, and deformation originating from the base end region V is more effectively suppressed. In addition, since the bulging portions 7 are connected by the upper and lower connecting portions (23, 24), the load from the luggage board LB is distributed to multiple target support portions (2A, 2B) that are separated vertically, and the load on each target support portion (2A, 2B) is reduced.

[0061] In this embodiment, the upper and lower connecting portion (here, the first upper and lower connecting portion 23) that overlaps with the area of ​​the housing portion 8 is also connected to the housing portion 8. As a result, the number of connection points (support points, contact points) of the side trim 1 to the upper and lower connecting portion (23) increases, and as a result, the overall deformation of the side trim 1 is suppressed, as is the deformation originating from the base end region V. Furthermore, in this embodiment, since the housing portion 8 is located in the area between the multiple support portions (2A, 2B, 2C) of the reference wall 1a, the deformation of the entire side trim 1 and the base end region V is suppressed more effectively.

[0062] In this embodiment, each target support portion (2A, 2B) of the side trim 1 is connected to the quarter panel 10 at the bulging portion 7 of the base end region V, and deformation of the target support portions (2A, 2B) is effectively suppressed with a simple structure. Since the bulging portion 7 has an upwardly convex arc cross-sectional shape, it has an upwardly convex arch-shaped support structure, and deformation is effectively suppressed. Furthermore, the bulging portions 7 are provided at multiple locations in the base end region V corresponding to the multiple target support portions (2A, 2B) that are spaced apart in the vehicle's longitudinal direction, and the multiple bulging portions arranged front to back are connected to each other by front to rear connecting portions (21, 22). As a result, the range over which the deformation suppression effect of each target support portion (2A, 2B) in the base end region V is extended in the vehicle's longitudinal direction, and deformation of the base end region V is suppressed very effectively. In addition, since the front to rear connecting portions (21, 22) are connected not only to the bulging portions 7 but also to the protruding portion 9, the overall deformation of the side trim 1 is suppressed more effectively.

[0063] In this embodiment, the lowest support portion 2C is supported by the wheelhouse 11 via a cushioning member 30 positioned between its mounting wall 3 and the wheelhouse 11, thereby suppressing vertical deformation of the lowest support portion 2C.

[0064] Although the target support sections (2A, 2B) are in two stages, there may be three or more stages. In this case, the front and rear connecting sections (21, 22) and the bulging section 7 may be provided for each base end region V corresponding to each target support section, the housing section 8 may be provided between each of the multiple support sections, and the upper and lower connecting sections (23, 24) may be extended according to the number of stages. Furthermore, although the first front and rear connecting section 21, which is the upper front and rear connecting section, is assumed to be a reinforcing main body section 20a that is directly fixed to the quarter panel 10, this is not limited to this, and the second front and rear connecting section 22, which is the lower front and rear connecting section, may also be directly fixed to the quarter panel 10. Alternatively, both the first front and rear connecting section 21 and the second front and rear connecting section 22 may be directly fixed to the quarter panel 10. In this case, the reinforcing member 20 may not have upper and lower connecting sections (23, 24) and upper and lower connecting sections 25 for protruding parts.

[0065] The reinforcing member 20 is fixed to the portion of the quarter panel 10 above the wheelhouse 11, but is not limited to this. The reinforcing member 20 may be fixed to the wheelhouse 11, or to a highly rigid portion such as a side member or side sill that constitutes a vehicle body frame member.

[0066] A cushioning member may be placed inside (in the hollow portion of) the multiple support parts (2A, 2B). In this case, the cushioning member inside the support parts (2A, 2B) may be directly supported by the portion of the quarter panel 10 above the wheelhouse 11 or by the wheelhouse 11, or it may be indirectly supported, for example, via a reinforcing member 20.

[0067] Furthermore, in this embodiment, upper and lower connecting parts (here, the first upper and lower connecting part 23) that connect multiple bulging parts 7 connect the bulging parts 7 and the housing parts 8, but this is not the only way to go. As shown in Figure 8, which illustrates a modified example of the reinforcing member 20, other members (first intermediate connecting part 28, second intermediate connecting part 29) that constitute part of the reinforcing member 20 and do not connect multiple bulging parts 7 may connect one bulging part 7 and at least one housing part 8. Specifically, in Figure 8, the reinforcing member 20 is composed of a first inclined connecting part 26, a second inclined connecting part 27, a first intermediate connecting part 28, and a second intermediate connecting part 29 instead of multiple front and rear connecting parts (21, 22), multiple upper and lower connecting parts (23, 24), and a connecting part for protruding parts 25. In this example, the first inclined connecting part 26 and the second inclined connecting part 27 are arranged to intersect each other diagonally and have the function of serving as both front and rear connecting parts and upper and lower connecting parts. Specifically, the first inclined connecting section 26 connects the rear bulge 7 of the first support section 2A to another housing section 8' and the lower protrusion 9, and the second inclined connecting section 27 connects the rear bulge 7 of the second support section 2B to another housing section 8' and the lower housing section 8. Furthermore, the first intermediate connecting section 28 connects the front bulge 7 of the first support section 2A to the upper housing section 8 and another housing section 8', and the second intermediate connecting section 29 connects the front bulge 7 of the second support section 2B to the lower housing section 8.

[0068] Furthermore, it is conceivable that one support portion 2C corresponding to the lowest support portion 2C is provided on the side trim 1, and the target support portions (2A, 2B) are not provided on the side trim 1. In this case as well, the lowest support portion 2C may be supported by the wheelhouse 11 via a cushion member 30 placed between its mounting wall 3 and the wheelhouse 11.

[0069] The description of this embodiment is illustrative for explaining the present invention and does not limit the invention as described in the claims. Furthermore, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications are possible within the technical scope described in the claims.
