Description

Technical Field

[0001] The present invention relates to a vehicle interior side structure for supporting a luggage board.

Background Art

[0002] In a vehicle having a luggage compartment at the rear of the vehicle interior, the luggage compartment may be partitioned by a luggage board (also referred to as a partition plate or the like). In such a vehicle, a protrusion for supporting the luggage board is formed on each of the side walls of the luggage compartment (that is, the rear side portion of the side walls of the vehicle interior).

[0003] For example, in the luggage compartment structure of a vehicle disclosed in Patent Document 1, a pair of protrusions spaced apart from each other in the front-rear direction protrude inward in the vehicle width direction at the lower portion of a side trim that is a side wall of the luggage compartment. And this luggage compartment structure can partition (separate) the luggage compartment in the front-rear direction by supporting the luggage board in a vertically placed posture between the pair of protrusions. And the side trim is often a resin molded product.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Incidentally, when a load is applied to a luggage board in a vertical position during driving or when loading luggage into the cargo area, this load can be transmitted to a protrusion formed on the side wall of the cargo area. Therefore, in the structure of Patent Document 1, depending on the magnitude of the load acting on the luggage board, deformation or damage may occur to the part (protrusion) that supports the luggage board in the side trim (i.e., the side wall of the cargo area), making it difficult to support the luggage board in the desired position (cargo area compartment state).

[0006] The present invention was made to solve the above problems, and its objective is to provide a vehicle interior side structure having a structure that can improve the rigidity for supporting a luggage board in a vertical position. [Means for solving the problem]

[0007] A vehicle interior side structure according to one aspect of the present invention for achieving the above objective includes a front support portion that protrudes inward in the vehicle width direction from the side wall of the vehicle interior, and a rear support portion that protrudes inward in the vehicle width direction from the side wall and is spaced rearward in the vehicle longitudinal direction relative to the front support portion, and the outer edge portion in the vehicle width direction of the luggage board placed in the vehicle interior is inserted between the front support portion and the rear support portion to support the luggage board in a vertical position. The front support portion and the rear support portion of the vehicle interior side structure support the luggage board in a vertical position at a position where the upper part of the luggage board overlaps with the pillar that forms the rear edge of the opening of the rear side door opening in the vehicle width direction. Furthermore, a vehicle interior side structure relating to another aspect of the present invention includes a front support portion that protrudes inward in the vehicle width direction from the side wall of the vehicle interior, and a rear support portion that protrudes inward in the vehicle width direction from the side wall and is spaced rearward in the vehicle longitudinal direction relative to the front support portion, and the outer edge portion in the vehicle width direction of the luggage board placed in the vehicle interior is inserted between the front support portion and the rear support portion, thereby supporting the luggage board in a vertical position. The front support portion of this vehicle interior side structure is provided in a position that overlaps with the pillar forming the rear edge of the rear side door opening in the vehicle width direction. Furthermore, a vehicle interior side structure relating to yet another aspect of the present invention includes a front support portion that protrudes inward in the vehicle width direction from the side wall of the vehicle interior, and a rear support portion that protrudes inward in the vehicle width direction from the side wall and is spaced rearward in the vehicle longitudinal direction relative to the front support portion, and the outer edge portion in the vehicle width direction of the luggage board placed in the vehicle interior is inserted between the front support portion and the rear support portion to support the luggage board in a vertical position. The front support portion and the rear support portion of this vehicle interior side structure support the luggage board in a vertical position at a position where the upper part of the luggage board overlaps with the pillar that forms the front edge of the quarter panel in the vehicle width direction. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a vehicle interior side structure having a structure that can improve the rigidity for supporting the luggage board in a vertical position. [Brief explanation of the drawing]

[Figure 11] This is an enlarged plan view of the main part of the side wall as seen from inside the cargo compartment. [Modes for carrying out the invention]

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

[0011] Figure 1 is a partial perspective view including the side wall of the passenger compartment side structure according to one embodiment of the present invention, and Figure 2 is a conceptual diagram for explaining the support state of the luggage board. In the figures, 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 looks forward to the front of the vehicle. Arrow U indicates the upward direction in the vertical direction of the vehicle.

[0012] Referring to Figures 1 and 2, the passenger compartment 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 11, which is opened and closed by the front side door (not shown), the rear side door opening 12, which is opened and closed by the rear side door (not shown), and the back door opening 13, which is opened and closed by the back door (not shown).

[0013] In the passenger compartment of the vehicle, for example, a front seat 14 (removed in FIG. 1) and a rear seat 15 are arranged. The seat back 15a of the rear seat 15 is foldable. When the rear seat 15 is upright, the area behind the seat back 15a of the rear seat 15 in the passenger compartment can be used as a luggage compartment S. Here, the seat portion 15b of the rear seat 15 is movably supported while maintaining the seat surface substantially parallel between the seating position and a storage position that is forward and downward with respect to the seating position. The rear seat 15 is moved and operated between a seating state (see FIGS. 1 and 2) where the seat portion 15b is located at the seating position and the seat back 15a is upright, and a storage state (see FIGS. 3 and 4 described later) where the seat portion 15b is moved to the storage position and the seat back 15a is folded forward, and is configured to be switchable between the seating state and the storage state.

[0014] FIG. 3 is a partial perspective view showing the state in which the rear seat 15 is stored in FIG. 1, and FIG. 4 is a conceptual diagram showing the state in which the rear seat 15 is stored in FIG. 2. Referring to FIGS. 3 and 4, in the storage state, the height position of the back surface (the surface facing upward in this state) of the seat back 15a of the rear seat 15 and the height position of the upper surface 16a of the floor portion (also referred to as the rear floor) 16 at the rear of the passenger compartment are configured to be substantially the same as each other. Referring to FIG. 3, in the storage state, the gap between the rear portion of the rear seat 15 and the floor portion 16 can be blocked by an auxiliary board 17 (a covering portion) provided separately from the luggage board 10. In FIG. 4, the illustration of the auxiliary board 17 is omitted.

[0015] Referring to FIGS. 1 to 4, the side structure of the passenger compartment of the present embodiment has a structure for supporting the luggage board 10 in a vertically placed posture (that is, a posture extending in the vehicle width direction and the vehicle vertical direction) in the luggage compartment S.

[0016] The luggage board 10 is a plate member arranged in the luggage compartment S and capable of partitioning and separating the luggage compartment S. The luggage board 10, which will be described in detail later, is formed, for example, in a substantially rectangular shape in plan view.

[0017] When the rear seat 15 is in the seated state (see FIGS. 1 and 2), when the luggage board 10 is arranged in the luggage compartment S in the vertical posture, the luggage compartment S is partitioned in the vehicle longitudinal direction and separated into two regions. And, in the state where the luggage board 10 is arranged in the vertical posture, when the rear seat 15 is moved and switched from the seated state (see FIGS. 1 and 2) to the stored state (see FIGS. 3 and 4), the area (space) that can be used as the luggage compartment S in the passenger compartment is expanded forward.

[0018] The side trim 1 as the side wall of the rear region (luggage compartment S) in the passenger compartment is included as a main member in the side structure of the passenger compartment of the present embodiment. That is, the side trim 1 of the present embodiment is the rear portion of the side wall of the vehicle, and constitutes the end wall in the vehicle width direction of the luggage compartment S. The side trim 1 is provided on both sides in the vehicle width direction of the floor portion 16 at the rear of the passenger compartment. The side trim 1 is also called a luggage side wall or a rear side trim. In FIGS. 1 to 4, the side trim 1 on the right side in the vehicle width direction is shown, and in FIGS. 1 and 3, the side trim 1 on the left side in the vehicle width direction is removed.

[0019] 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) from the viewpoint of preventing sink marks during molding. The lower region of the side trim 1 bulges greatly inward in the vehicle width direction corresponding to the wheelhouse of the vehicle body. In front of the side trim 1, a center pillar trim 18 (see FIGS. 1 and 3) is provided. The front edge of the side trim 1 forms the opening rear edge of the rear side door opening 12, and the rear edge of the center pillar trim 18 forms the opening front edge of the rear side door opening 12. In the present embodiment, a trim forming the opening side edge and the opening lower edge of the back door opening 13 is integrally formed at the rear of the side trim 1. The front edge of the side trim 1 extends along the pillar 19 (see FIG. 11 described later) at the front edge of the quarter panel in the form of a metal plate constituting a part of the vehicle body and is attached to the pillar 19. This pillar 19 forms the opening rear edge of the rear side door opening 12 together with the front edge of the side trim 1.

[0020] Figure 5 is a perspective view of the side trim 1. As described above, the side trim 1 is provided on both sides in the vehicle width direction of the floor portion 16 at the rear of the passenger compartment. Figure 5, and Figures 6 to 8, 10 and 11 described later, show the right side trim 1. The left side trim 1 has the same shape as the right side trim 1, except that it is symmetrical to the right side trim 1 in the vehicle width direction.

[0021] The side trim 1 is provided with a front support portion 2a and a rear support portion 2b for supporting the luggage board 10 in a vertical position. Each of the front support portion 2a and the rear support portion 2b constitutes a part of the side trim 1. The front support portion 2a protrudes inward in the vehicle width direction from a predetermined reference surface 1a on the inner surface of the side trim 1 in the vehicle width direction (i.e., the design surface facing the passenger compartment). The rear support portion 2b protrudes inward in the vehicle width direction from the reference surface 1a of the side trim 1 and is spaced rearward in the vehicle longitudinal direction relative to the front support portion 2a.

[0022] In this embodiment, the front support portion 2a and the rear support portion 2b are provided in the lower region of the side trim 1 in the vehicle's vertical direction. The predetermined reference surface 1a of the side trim 1 is, for example, a flat surface set on the upper side of the side trim 1 in the vehicle's vertical direction and on the front side in the vehicle's longitudinal direction, facing the passenger compartment (cargo compartment S). The front support portion 2a and the rear support portion 2b are formed continuously with the reference surface portion of the side trim 1, which is the region where the reference surface 1a is set. The front support portion 2a and the rear support portion 2b have a thickness (plate thickness) that is approximately the same as the thickness (plate thickness) of the reference surface portion of the side trim 1.

[0023] The front support portion 2a has a front upper wall portion 2a1 that protrudes inward in the vehicle width direction from the reference surface 1a, and a rear end wall 2a2 that forms the rear end of the front support portion 2a in the vehicle longitudinal direction. The front upper wall portion 2a1 extends in the vehicle longitudinal direction on the lower side and front edge side of the side trim 1. The rear end wall 2a2 extends downward from the rear end of the front upper wall portion 2a1.

[0024] The rear support portion 2b has a rear upper wall portion 2b1 that protrudes inward in the vehicle width direction from the reference surface 1a, and a front end wall 2b2 that forms the front end of the rear support portion 2b in the vehicle longitudinal direction. The rear upper wall portion 2b1 extends in the vehicle longitudinal direction at the same height as the front upper wall portion 2a1. The front end wall 2b2 extends downward from the front end of the rear upper wall portion 2b1.

[0025] The rear end wall 2a2 and the front end wall 2b2 constitute a part of the side trim 1 and are spaced apart from each other in the longitudinal direction on the vehicle width side of the reference plane 1a of the side trim 1. The rear end wall 2a2 is spaced forward from the front end wall 2b2. The reference separation distance D0, which is the separation distance between the rear end wall 2a2 and the front end wall 2b2, is set to a dimension slightly larger than the thickness of the luggage board 10. Although not particularly limited, in this embodiment, the length of the front support portion 2a protruding inward from the reference plane 1a in the vehicle width direction is shorter than the length of the rear support portion 2b protruding inward from the reference plane 1a in the vehicle width direction, and the dimension of the rear end wall 2a2 in the vehicle width direction is smaller than the dimension of the front end wall 2b2 in the vehicle width direction.

[0026] When the outer edge portion 10a of the luggage board 10, which is the outer edge in the vehicle width direction, is inserted (fitted) into the area V between the rear end wall 2a2 and the front end wall 2b2 by an occupant or the like, the outer edge portion 10a of the luggage board 10 is sandwiched between the rear end wall 2a2 and the front end wall 2b2. As a result, the luggage board 10 is supported in a longitudinal position in the cargo compartment S via the front support portion 2a and the rear support portion 2b of the left and right side trims 1.

[0027] In other words, in this embodiment, the side structure of the passenger compartment supports the luggage board 10 in a vertical position within the passenger compartment by inserting the outer edge portion 10a, which is the outer edge portion in the vehicle width direction of the luggage board 10 placed inside the passenger compartment, between the rear end wall 2a2 of the front support portion 2a and the front end wall 2b2 of the rear support portion 2b.

[0028] Incidentally, when a load is applied to the luggage board 10, which is positioned vertically, from the front-rear direction of the vehicle, such as when driving or loading luggage into the cargo area, this load can be mainly transmitted to the rear end wall 2a2 and the front end wall 2b2 of the side trim 1. Therefore, depending on the magnitude of the load acting on the luggage board 10, deformation or damage may occur to the rear end wall 2a2 and the front end wall 2b2, which are the main parts of the side trim 1 that support the luggage board 10 in a vertical position, making it difficult to support the luggage board 10 in a vertical position. In particular, if the vertical dimension of the luggage board 10 is increased, the load such as moment acting on the rear end wall 2a2 and the front end wall 2b2 tends to increase due to the lever principle, and as a result, the possibility of deformation may increase. In response to this, the side structure of the passenger compartment according to this embodiment has a structure (deformation suppression structure) described below in order to effectively suppress deformation of the rear end wall 2a2 and the front end wall 2b2.

[0029] Next, the deformation suppression structure will be described in detail. Figure 6 is a plan view of the side trim 1 as seen from inside the cargo compartment S, Figure 7 is a cutaway model of the side trim 1 cut at the position of line AA shown in Figure 6, and Figure 8 is a cross-sectional view of the side trim 1 at the position of line AA shown in Figure 6.

[0030] Referring to Figures 5 to 8, the passenger compartment side structure in this embodiment includes a connecting portion 3 that is located inward in the vehicle width direction from the reference plane 1a of the side trim 1 and connects the rear end wall 2a2 and the front end wall 2b2.

[0031] In this embodiment, the connecting portion 3 constitutes a part of the side trim 1 and is integrally molded with the front support portion 2a and the rear support portion 2b. In this embodiment, the connecting portion 3 has an end wall portion 3a, an extended portion 3b, and a connecting side wall portion 3c. The connecting portion 3 has a thickness (plate thickness) that is approximately the same as the thickness (plate thickness) of the reference surface portion of the side trim 1.

[0032] The end wall portion 3a is the part that has an upper surface facing upward between the rear end wall 2a2 and the front end wall 2b2. In this embodiment, the end wall portion 3a has a stepped cross-section and extends in the longitudinal direction of the vehicle. That is, a stepped wall 3a1 offset in the vertical direction of the vehicle is provided at an intermediate position in the vehicle width direction of the end wall portion 3a. The uppermost surface 3a2 of the upper surface of the end wall portion 3a is formed as a flat surface. In this case, the portion of the end wall portion 3a that is inward in the vehicle width direction from the stepped wall 3a1 is inclined downward in the vehicle width direction.

[0033] The extension portion 3b is the part that extends downward from the inner end of the end wall portion 3a in the vehicle width direction. Here, the extension portion 3b extends downward from the end of the part of the end wall portion 3a that is inward in the vehicle width direction from the stepped wall 3a1.

[0034] The connecting side wall portion 3c extends inward in the vehicle width direction from the reference surface 1a of the side trim 1, and then extends downward on the vehicle. Here, the portion 3c1 of the connecting side wall portion 3c that extends inward in the vehicle width direction from the reference surface 1a connects the front upper wall portion 2a1 of the front support portion 2a and the rear upper wall portion 2b1 of the rear support portion 2b, and together with the front upper wall portion 2a1 and the rear upper wall portion 2b1, forms a flat surface that faces upward. The side wall portion 3c2, which is the portion of the connecting side wall portion 3c that extends in the vehicle vertical direction, connects the inner end in the vehicle width direction of the portion 3c1 that extends from the reference surface 1a of the connecting side wall portion 3c and the outer end in the vehicle width direction of the end wall portion 3a. In other words, the connecting side wall portion 3c has a stepped cross-section, similar to the end wall portion 3a. The majority of the connecting side wall portion 3c is composed of the side wall portion 3c2.

[0035] As described above, the front end of the luggage board insertion area V is defined by the rear end wall 2a2 of the front support portion 2a, the rear end of area V is defined by the front end wall 2b2 of the rear support portion 2b, and the outer end of area V in the vehicle width direction is defined by the side wall portion 3c2 of the connecting side wall portion 3c. In this embodiment, the lower end of area V is defined by the end wall portion 3a. In other words, a groove for inserting the luggage board is formed inside the rear end wall 2a2, the front end wall 2b2, the end wall portion 3a, and the side wall portion 3c2, and this groove is open upward in the vehicle vertical direction and inward in the vehicle width direction. Furthermore, the connecting portion 3 is formed in a continuous order from top to bottom: the connecting side wall portion 3c, the end wall portion 3a, and the extension portion 3b, and the overall structure has a stepped cross-section.

[0036] Next, the shape of the luggage board 10 and its support structure will be described. Figure 9 is a plan view of the luggage board 10, and Figure 10 is a cross-sectional view illustrating the support structure of the luggage board.

[0037] The luggage board 10 has a predetermined thickness and is formed in a plate shape. In a plan view, the luggage board 10 has an overall roughly rectangular shape that is long in the vehicle width direction. In this embodiment, the luggage board 10 has a first contact portion 10b, a second contact portion 10c, and an extension portion 10d.

[0038] The first contact portion 10b is the part that contacts the uppermost surface 3a2 of the end wall portion 3a of the right side (one side in the vehicle width direction) of the side trim 1 when the luggage board 10 is positioned vertically within the vehicle compartment (cargo area S). In the vertical position, the first contact portion 10b is located at the lower end of the right side outer edge portion 10a of the side trim 1 and has a surface facing downward.

[0039] The second contact portion 10c is the part that contacts the uppermost surface 3a2 of the end wall portion 3a of the left side (the other side in the vehicle width direction) of the side trim 1 when the luggage board 10 is positioned vertically within the vehicle compartment (cargo area S). In the vertical position, the second contact portion 10c is located at the lower end of the left outer edge portion 10a of the side trim 1 and has a surface facing downwards.

[0040] The extension 10d is located between the first contact portion 10b and the second contact portion 10c and extends downward from the first contact portion 10b and the second contact portion 10c. The extension 10d constitutes the lower edge of the luggage board 10.

[0041] Furthermore, a first recess 10e and a second recess 10f are formed in the outer edge 10a of the luggage board 10. Each of the first recess 10e and the second recess 10f is a notch that opens outward in the vehicle width direction, and the second recess 10f is provided above the first recess 10e.

[0042] Referring to Figure 10, in this embodiment, the height position of the uppermost surface 3a2 of the end wall portion 3a in the vehicle's vertical direction relative to the floor surface 16a is set such that a gap G is created between the lower end of the extension portion 10d of the vertically positioned luggage board 10 and the upper floor surface 16a of the passenger compartment (cargo area S).

[0043] In this embodiment, the side structure of the passenger compartment has a guide structure that acts as a guide when inserting the luggage board 10 between the rear end wall 2a2 and the front end wall 2b2.

[0044] Returning to Figures 5 to 8, in this embodiment, the side trim 1 further includes a first front guide portion 4a and a first rear guide portion 4b that are spaced apart from each other in the front-rear direction, and a second front guide portion 5a and a second rear guide portion 5b that are spaced apart from each other in the front-rear direction. In this embodiment, the front guide portions (4a, 5a) and the rear guide portions (4b, 5b) all constitute a part of the side trim 1 and are integrally molded with the front support portion 2a, the rear support portion 2b, and the connecting portion 3.

[0045] In the side trim 1, each front guide section (4a, 5a) is located above the front support section 2a, each rear guide section (4b, 5b) is located above the rear support section 2b, the second front guide section 5a is located above the first front guide section 4a, and the second rear guide section 5b is located above the first rear guide section 4b.

[0046] Each front guide section (4a, 5a) protrudes inward from the reference plane 1a in the vehicle width direction above the front support section 2a, and each rear guide section (4b, 5b) protrudes inward from the reference plane 1a in the vehicle width direction above the rear support section 2b.

[0047] The first front guide section 4a and the first rear guide section 4b are arranged to be spaced apart from each other in the vehicle's longitudinal direction, and the second front guide section 5a and the second rear guide section 5b are arranged to be spaced apart from each other in the vehicle's longitudinal direction. In other words, the first rear guide end wall 4a1, which forms the rear end of the first front guide section 4a in the vehicle's longitudinal direction, and the first front guide end wall 4b1, which forms the front end of the first rear guide section 4b in the vehicle's longitudinal direction, are spaced apart from each other in the longitudinal direction. Furthermore, the second rear guide end wall 5a1, which forms the rear end of the second front guide section 5a in the vehicle's longitudinal direction, and the second front guide end wall 5b1, which forms the front end of the second rear guide section 5b in the vehicle's longitudinal direction, are spaced apart from each other in the longitudinal direction.

[0048] The first front guide section 4a and the second rear guide section 5b are positioned at different locations relative to each other in the vehicle's vertical direction, and the second front guide section 5a and the first rear guide section 4b are positioned at different locations relative to each other in the vehicle's vertical direction.

[0049] Figure 11 is an enlarged plan view of the main part of the side trim 1 as seen from inside the passenger compartment (cargo area S).

[0050] Let's consider each set of guide sections arranged front to back (i.e., the first front guide section 4a and the first rear guide section 4b, or the second front guide section 5a and the second rear guide section 5b). In this case, when the luggage board 10 is in a vertical position, one of the guide rear end walls (4a1, 5a1) and the guide front end walls (4b1, 5b1) is positioned to abut against the luggage board 10, while the other of the guide rear end wall (4a1, 5a1) and the guide front end wall (4b1, 5b1) is positioned to be separated from the luggage board 10.

[0051] In this embodiment, with the set of the first front guide section 4a and the first rear guide section 4b, when the luggage board 10 is in a vertical position, the front end wall 4b1 of the first guide abuts against the luggage board 10, and the rear end wall 4a1 of the first guide is separated from the luggage board 10. Conversely, with the set of the second front guide section 5a and the second rear guide section 5b, when the luggage board 10 is in a vertical position, the rear end wall 5a1 of the second guide abuts against the luggage board 10, and the front end wall 5b1 of the second guide is separated from the luggage board 10. In other words, with the set of the uppermost guide sections (5a, 5b), the rear end wall (5a1) of the guide facing backward abuts against the luggage board 10. Therefore, focusing on the uppermost guide section set (5a, 5b), one of the guide rear end wall and guide front end wall that abuts against the luggage board 10 is the guide rear end wall (i.e., the second guide rear end wall 5a1).

[0052] Next, we consider each set of guide sections that are positioned at different locations in the vertical direction of the vehicle (i.e., the first front guide section 4a and the second rear guide section 5b, and the second front guide section 5a and the first rear guide section 4b). In this case, when the luggage board 10 is in a vertical position, in the set of the first front guide section 4a and the second rear guide section 5b, the first guide rear end wall 4a1 and the second guide front end wall 5b1 are positioned at a distance from the luggage board 10. And, when the luggage board 10 is in a vertical position, in the set of the second front guide section 5a and the first rear guide section 4b, the second guide rear end wall 5a1 and the first guide front end wall 4b1 are positioned in contact with the luggage board 10. Therefore, in this embodiment, the front guide portion (here, the second front guide portion 5a) included in the set of guide portions that contact the luggage board 10, which are arranged at different positions in the vertical direction of the vehicle, is positioned higher in the vertical direction than the rear guide portion (here, the first rear guide portion 4b).

[0053] Referring to Figure 11, in this embodiment, the first separation distance D1, which is the separation distance between the first guide rear end wall 4a1 and the first guide front end wall 4b1, is set to be greater than the reference separation distance D0, which is the separation distance between the rear end wall 2a2 of the front support portion 2a and the front end wall 2b2 of the rear support portion 2b. The second separation distance D2, which is the separation distance between the second guide rear end wall 5a1 and the second guide front end wall 5b1, is set to be greater than the reference separation distance D0.

[0054] Furthermore, the second separation distance D2 is set to be greater than the first separation distance D1. In other words, the relationship D2 > D1 > D0 holds true. In addition, the difference value ΔD02 between the reference separation distance D0 and the second separation distance D2 is set to be greater than the difference value ΔD01 between the reference separation distance D0 and the first separation distance D1 (ΔD02 > ΔD01). As a result, when an occupant or the like inserts the luggage board 10 from above into the luggage board insertion area V, the luggage board 10 is easier to insert. And because the difference value ΔD01 is smaller than the difference value ΔD02, the gap with the luggage board 10 gradually decreases during the insertion work, and as a result, the positioning of the luggage board 10 can be easily performed. Furthermore, the gap corresponding to the difference value ΔD01 is in front of the luggage board 10, and the gap corresponding to the difference value ΔD02 is in rear of the luggage board 10. This allows occupants to insert the luggage board 10 while it is tilted upwards and towards the rear, thus improving the efficiency of the process of positioning the luggage board 10 in a vertical orientation.

[0055] In this embodiment, the first positioning projection 6 is provided on the upper surface of the rear upper wall portion 2b1 of the rear support portion 2b, the second positioning projection 7 is provided on the upper surface of the first rear guide portion 4b, and the third positioning projection 8 is provided on the upper surface of the second rear guide portion 5b. The first positioning projection 6 is provided near the front end wall 2b2 and the connecting portion 3 of the rear support portion 2b. As a result, the rigidity of the surrounding portions of the connecting portion 3 and the front end wall 2b2 of the side trim 1 is improved. Furthermore, the front end of the first positioning projection 6 is positioned directly above the front end wall 2b2 of the rear support portion 2b. As a result, the first positioning projection 6 can withstand loads that may be transmitted to the luggage board 10 in a vertical position.

[0056] In this embodiment, the side trim 1 can support the luggage board 10 not only in a vertical position within the cargo compartment S, but also in a horizontal position (i.e., in a position extending in the vehicle width direction and the vehicle front-rear direction).

[0057] For example, the outer edge 10a of the luggage board 10 can be placed on the upper surface of the front support portion 2a (front upper wall portion 2a1) and the rear support portion 2b (rear upper wall portion 2b1) of the side trim 1, the upper surface of the first front guide portion 4a and the upper surface of the first rear guide portion 4b, and the upper surface of the second front guide portion 5a and the upper surface of the second rear guide portion 5b. As a result, the luggage board 10 can be supported in a transverse position at multiple locations (in this case, three locations) in the vertical direction of the vehicle. In this transverse position, the luggage board 10 partitions (separates) the cargo compartment S in the vertical direction of the vehicle. In the transverse position, the first positioning projection 6 fits into the first recess 10e of the luggage board 10, and any of the positioning projections (6, 7, 8) can fit into the second recess 10f.

[0058] In this embodiment, each front guide portion (4a, 5a) is positioned to overlap with the pillar 19 at the front edge of the quarter panel, which is a rigid member that constitutes part of the vehicle body, when viewed from the inside in the vehicle width direction. As a result, even if each front guide portion (4a, 5a) receives a load from the luggage board 10, the load is received by the pillar 19, which is a highly rigid member, so deformation of each front guide portion (4a, 5a) is effectively suppressed.

[0059] Returning to Figure 10, the first recess 10e and the second recess 10f of the luggage board 10 are positioned so as not to overlap with the front support portion 2a and the rear support portion 2b, as well as the first front guide portion 4a and the first rear guide portion 4b, when the luggage board 10 is in a vertical position and viewed from one side in the front-rear direction of the vehicle. As a result, sufficient contact area is ensured between the outer edge portion 10a of the luggage board 10 and these portions (2a, 2b, 4a, 4b), resulting in good contact.

[0060] Referring to Figure 10, the wheelhouse 21, which constitutes part of the vehicle body, is located below the front support portion 2a and the rear support portion 2b. A cushioning material 20 made of foamed polypropylene or the like is supported on the upper surface of the wheelhouse 21, and the front upper wall portion 2a1 of the front support portion 2a and the rear upper wall portion 2b1 of the rear support portion 2b are supported on the upper surface of the cushioning material 20. As a result, any loads that may act on the front upper wall portion 2a1 and the rear upper wall portion 2b1 can be absorbed by the wheelhouse 21 via the cushioning material 20. This effectively suppresses deformation of the front support portion 2a and the rear support portion 2b.

[0061] Furthermore, when the vertically positioned luggage board 10 receives a load from the upper rear, a force may be generated that causes the upper part of the luggage board 10 to move forward and the lower part of the luggage board 10 to move backward. Referring to Figure 8, the amount of inward protrusion of the rear support portion 2b in the vehicle width direction is greater than the amount of inward protrusion of the front support portion 2a in the vehicle width direction, and the load per unit area that can be received by the front end wall 2b2 of the rear support portion 2b is smaller than the load per unit area that can be received by the rear end wall 2a2 of the front support portion 2a. In addition, the length of the rear support portion 2b in the vehicle longitudinal direction is set to be longer than the length of the front support portion 2a in the vehicle longitudinal direction.

[0062] As described above, the vehicle compartment side structure according to this embodiment includes a front support portion 2a, a rear support portion 2b, and a connecting portion 3 located inward in the vehicle width direction from the reference plane 1a of the side trim 1. The outer edge portion 10a of the luggage board 10, which is placed in the luggage compartment S, is inserted between the rear end wall 2a2 of the front support portion 2a and the front end wall 2b2 of the rear support portion 2b, thereby supporting the luggage board 10 in a vertical position within the luggage compartment S. The rear end wall 2a2 of the front support portion 2a and the front end wall 2b2 of the rear support portion 2b are connected by the connecting portion 3. Therefore, the rigidity of the portion of the side trim 1 including the rear end wall 2a2 and the front end wall 2b2, which are the main parts that support the luggage board 10 in a vertical position, is effectively increased, thereby improving the support rigidity for supporting the luggage board 10 in a vertical position. As a result, even when a load acts on the luggage board 10, which is positioned vertically, from the front-rear direction of the vehicle during driving or when loading luggage into the cargo area, and this load is transmitted to the rear end wall 2a2 and front end wall 2b2 of the side trim 1, deformation or damage to the rear end wall 2a2 and front end wall 2b2 is effectively suppressed or prevented. Therefore, the luggage board 10 is supported in the desired position (cargo compartment state), and this state and position are maintained. Thus, the side structure of the vehicle compartment according to this embodiment has a structure that can improve the rigidity for supporting the luggage board 10 in a vertical position.

[0063] In this embodiment, the connecting portion 3 has an end wall portion 3a having an upper surface facing upward between the rear end wall 2a2 and the front end wall 2b2, and an extension portion 3b extending downward from the inner end of the end wall portion 3a in the vehicle width direction. In other words, the connecting portion 3 is bent vertically between the end wall portion 3a and the extension portion 3b. This increases the rigidity of the connecting portion 3 in the vehicle longitudinal direction, and as a result, the support rigidity of the rear end wall 2a2 and the front end wall 2b2 by the connecting portion 3 is effectively increased. Furthermore, in this embodiment, the portion of the end wall portion 3a that is inward in the vehicle width direction from the stepped wall 3a1 is inclined downward inward in the vehicle width direction. As a result, the connection area between the rear end wall 2a2 and the front end wall 2b2 is effectively increased compared to the case where the portion of the end wall portion 3a that is inward in the vehicle width direction from the stepped wall 3a1 extends horizontally. Furthermore, when the luggage board 10 comes into contact with the portion of the end wall 3a that is inward in the vehicle width direction from the stepped wall 3a1, the contact area between the end wall 3a and the luggage board 10 increases because the portion of the end wall 3a that is inward in the vehicle width direction from the stepped wall 3a1 is inclined.

[0064] In this embodiment, the end wall portion 3a of the connecting portion 3 has a stepped cross-section and extends in the longitudinal direction of the vehicle, so the cross-sectional area of ​​the end wall portion 3a increases. As a result, the rigidity of the end wall portion 3a in the longitudinal direction of the vehicle is further increased, and the support rigidity of the rear end wall 2a2 and the front end wall 2b2 by the connecting portion 3 is more effectively increased.

[0065] In this embodiment, the connecting portion 3 has a connecting side wall portion 3c that extends inward in the vehicle width direction from the reference surface 1a and then extends downward on the vehicle. Therefore, the rigidity of the portion of the connecting portion 3 above the end wall portion 3a is also improved, and the support rigidity of the rear end wall 2a2 and the front end wall 2b2 by the connecting portion 3 is further significantly increased.

[0066] In this embodiment, the luggage board 10 has contact portions (10b, 10c) that abut against the uppermost surface 3a2 of the end wall portion 3a of the side trim 1, and extension portions 10d that extend downward from the contact portions (10b, 10c). This makes it easy to set the contact position between the end wall portion 3a and the luggage board 10 at a relatively high position on the side trim 1. As a result, a support portion that supports the end wall portion 3a from below is easily secured, and the vertical support rigidity of the luggage board 10 can be easily improved.

[0067] In this embodiment, a gap G is provided between the lower end of the extension 10d of the vertically positioned luggage board 10 and the upper surface of the floor 16a. Therefore, the luggage board 10 does not come into contact with the floor portion 16, preventing scratches on the upper surface of the floor 16a, and thus the aesthetic appearance of the cargo area S can be maintained in good condition.

[0068] In this embodiment, focusing on each set of guide sections arranged front to back at the same height (i.e., the first front guide section 4a and the first rear guide section 4b, or the second front guide section 5a and the second rear guide section 5b), when the luggage board 10 is in a vertical position, one of the guide rear end walls (4a1, 5a1) and the guide front end walls (4b1, 5b1) abuts against the luggage board 10, while the other of the guide rear end wall (4a1, 5a1) and the guide front end wall (4b1, 5b1) is separated from the luggage board 10. In other words, in the front to back set of guide sections, the load transmitted to the luggage board 10 is received by one of the guide sections, while the other guide section is not in contact with the luggage board 10. As a result, insertion of the luggage board 10 into the board insertion area V from above becomes easier.

[0069] Here, if the vertical dimension of the luggage board 10 in a vertical position increases, the load (moment) acting on the rear end wall 2a2, front end wall 2b2, and connecting portion 3 (including end wall portion 3a, etc.), which are support points (support elements) for the luggage board 10 in the side trim 1, may increase due to the lever principle.

[0070] In this embodiment, when considering each set of guide sections arranged front to back at the same height, one of the guide rear end walls (4a1, 5a1) and the guide front end walls (4b1, 5b1) abuts against the luggage board 10 at a position higher than the support point (support element) in the vertical direction, and the load can be supported by this abutting guide rear end wall or guide front end wall. As a result, deformation of the rear end wall 2a2, the front end wall 2b2, and the connecting section 3 is suppressed.

[0071] Furthermore, when luggage is piled on the rear side of the luggage board 10, which is positioned vertically, the luggage on the upper side is often smaller. Therefore, when loading luggage into the cargo compartment S from the rear of the vehicle or when decelerating or stopping, the luggage on the upper side moves in the front-to-back direction, and a load is easily applied to the rear of the upper end of the luggage board 10. For this reason, when considering the set of guide parts arranged front to back, the side trim 1 is preferable to include a set of guide parts in which the front guide part abuts against the luggage board 10. In this embodiment, when considering the set of the uppermost guide parts (5a, 5b), one of the guide rear end wall and guide front end wall that abuts against the luggage board 10 is the guide rear end wall (i.e., the second guide rear end wall 5a1 of the second front guide part 5a). This second guide rear end wall 5a1 of the second front guide part 5a effectively absorbs the load acting on the luggage board 10 from the rear of the vehicle. As a result, deformation of the rear end wall 2a2, the front end wall 2b2, and the connecting portion 3 is effectively suppressed.

[0072] In this embodiment, two sets of guide sections are provided, each positioned at a different height (i.e., a first front guide section 4a and a second rear guide section 5b, and a second front guide section 5a and a first rear guide section 4b). In the vertical orientation, one set of guide sections (here, the first front guide section 4a and the second rear guide section 5b) is spaced apart from the luggage board 10, while the other set of guide sections (here, the second front guide section 5a and the first rear guide section 4b) is in contact with the luggage board 10. In other words, the side trim 1 has front guide sections (5a) and rear guide sections (4b) that are spaced apart from each other vertically and horizontally and in contact with the luggage board 10. As a result, the load transmitted to the luggage board 10 is absorbed, and deformation of the front support section 2a, rear support section 2b, connecting section 3, etc. is suppressed. Furthermore, by offsetting the contact point with the luggage board 10 in the vertical direction, when the luggage board 10 is installed in a vertical position, it becomes easier for the luggage board 10 to be inserted into the region V between the front support portion 2a and the rear support portion 2b.

[0073] In this embodiment, the front guide section (here, the second front guide section 5a) included in the set of guide sections arranged at different heights that contact the luggage board 10 is positioned higher in the vertical direction than the rear guide section (here, the first rear guide section 4b). As a result, when a load is likely to act on the rear of the upper end of the luggage board 10, the load can be received at the uppermost position, which is higher than the support point (support element), thereby suppressing deformation of the rear end wall 2a2, the front end wall 2b2, and the connecting section 3.

[0074] In this embodiment, the front guide section and the rear guide section are provided in two stages in the vertical direction above the front support section 2a and the rear support section 2b, but the invention is not limited to this, and may be provided in one stage. In other words, the side trim 1 may have only the first front guide section 4a and the first rear guide section 4b as the front guide section and the rear guide section, or only the second front guide section 5a and the second rear guide section 5b, or the front guide section and the rear guide section may be located at different height positions than these guide section sets. In the case of only the first front guide section 4a and the first rear guide section 4b, it is preferable that the rear guide end wall 4a1 of the front guide section 4a abuts against the luggage board 10.

[0075] Furthermore, for example, if the luggage board 10 is prone to receiving loads from the upper front, the opposite may be true: the amount of inward protrusion of the front support portion 2a in the vehicle width direction may be greater than the amount of inward protrusion of the rear support portion 2b in the vehicle width direction, and the length of the front support portion 2a in the vehicle longitudinal direction may be set to be longer than the length of the rear support portion 2b in the vehicle longitudinal direction.

[0076] In this embodiment, the connecting portion 3 is provided only between the front support portion 2a and the rear support portion 2b, but it is not limited to this, and the connecting portion 3 may also be provided between the front guide portions (4a, 5a) and the rear guide portions (4b, 5b). In this case, the connecting portion 3 for each guide portion should be located inward in the vehicle width direction from the reference plane 1a without interfering with the luggage board 10, and should connect the rear guide end walls (4a1, 5a1) of the front guide portion and the front guide end walls (4b1, 5b1) of the rear guide portion. Also, in this embodiment, the front support portion 2a and the rear support portion 2b connected by the connecting portion 3 are provided on the lower end portion of the side trim 1, but it is not limited to this. The front support portion 2a and the rear support portion 2b may be provided only at height positions corresponding to the first front guide portion 4a and the first rear guide portion 4b, or only at height positions corresponding to the second front guide portion 5a and the second rear guide portion 5b. In these cases, the lower end portion of the side trim 1 is provided with, for example, a front guide portion and a rear guide portion that are spaced apart from each other in the front-rear direction and are not connected by a connecting portion 3.

[0077] Furthermore, in this embodiment, the dimension of the rear end wall 2a2 in the vehicle width direction is smaller than the dimension of the front end wall 2b2 in the vehicle width direction, but this is not limited to this, and it may be the same as the dimension of the front end wall 2b2 in the vehicle width direction, or it may be larger than the dimension of the front end wall 2b2 in the vehicle width direction.

[0078] Furthermore, the portion of the end wall 3a that is inward in the vehicle width direction from the stepped wall 3a1 is inclined in the vehicle width direction, but is not limited to this, and may extend in an arc shape. In this case, the connection area between the rear end wall 2a2 and the front end wall 2b2 is increased even more effectively. Also, the end wall 3a has a stepped cross-section and extends in the vehicle longitudinal direction, but is not limited to this, and may extend in the horizontal direction, or may extend with an inward downward slope in the vehicle width direction as a whole.

[0079] 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.
