[0011] 《Embodiment》 [Vehicle Structure] As shown in FIG. 1, the vehicle structure 1 of the embodiment includes a back panel 21, a loading platform 3, a cargo box 4, a guard frame 8, and a rain gutter member 9. The back panel 21 is disposed behind the passenger compartment 2. The loading platform 3 is disposed behind the back panel 21. The cargo box 4 forms a space above the loading platform 3. The guard frame 8 protects the rear surface of the back panel 21. The rain gutter member 9 is disposed between the back panel 21 and the guard frame 8. One of the features of the vehicle structure 1 of the embodiment is that, as shown in FIG. 4, the vehicle structure 1 is characterized in that the cargo box 4 and the rain gutter member 9 are fixed to each other with a later-described abutting portion 51, which is a part of the cargo box 4, abutted against the upper surface 911 of the bottom portion 91a of the rain gutter member 9.

[0012] [Back Panel] The back panel 21 constitutes the boundary between the passenger compartment 2 and the loading platform 3. A rear window 21a is fitted to the upper part of the back panel 21 as shown in FIGS. 2 and 3.

[0013] [Loading Platform] As shown in Fig. 1, the loading platform 3 is an area where a load is placed to carry the load. The loading platform 3 has an upper surface 31 on which the load is placed. The upper surface 31 is configured to be generally planar. Although not shown in the figure, the upper surface 31 is provided with beads for reinforcement.

[0014] [Cargo Compartment Box] The cargo compartment box 4 of this example has a cover member 5, a back door 6, and a support member 7. The cover member 5 covers the upper, left, and right sides above the upper surface 31 of the loading platform 3. The back door 6 opens and closes behind the cover member 5. The support member 7 supports the cover member 5. The cover member 5 of this example has a front cover member 51 and a rear cover member 52. The support member 7 of this example has a frame 71, two base plates 72, and four slide rails 73.

[0015] (Front Cover Member) The front cover member 51 is disposed in front of the loading platform 3. As shown in Fig. 3, the shape of the front cover member 51 as viewed from the rear of the vehicle is U-shaped with an opening downward. The front cover member 51 of this example has a roof panel 51a, a left panel 51b, a right panel 51c, and an upper front wall portion 51d.

[0016] The roof panel 51a extends in the left-right direction. As shown in Fig. 4, the roof panel 51a covers above the front beam portion 71c of the support member 7 and the upper horizontal side portion 81 of the guard frame 8, which will be described later. The left panel 51b and the right panel 51c extend downward from the left and right edges of the roof panel 51a. The left panel 51b and the right panel 51c are integrally formed with the roof panel 51a. The lower end portions of the left panel 51b and the right panel 51c are fixed to the base plate 72, which will be described later.

[0017] As shown in FIG. 4, the upper front wall portion 51d protrudes downward from the front end of the roof panel 51a. The upper front wall portion 51d of this example is provided over the entire length of the front end of the roof panel 51a. Different from this example, the upper front wall portion 51d may be provided on a part of the front end of the roof panel 51a. The upper front wall portion 51d has a contact portion 511 that abuts against the upper surface 911 of the bottom portion 91a of the upper horizontal side portion 91 in the rain gutter member 9 described later. The contact portion 511 is provided at the lower end of the upper front wall portion 51d.

[0018] An aerodynamic part (not shown) may be provided between the roof panel 22 disposed above the passenger compartment 2 and the roof panel 51a of the front cover member 51. The space between the roof panel 22 and the roof panel 51a is covered from above by the aerodynamic part.

[0019] As shown in FIG. 3, the front cover member 51 may further have a left front wall portion 51e and a right front wall portion 51f. The left front wall portion 51e protrudes inward in the vehicle width direction, that is, to the right, from the front end of the left panel 51b. The right front wall portion 51f protrudes inward in the vehicle width direction, that is, to the left, from the front end of the right panel 51c. The configuration of the left front wall portion 51e is the same as that of the right front wall portion 51f. The following description will be made only for the right front wall portion 51f. The right front wall portion 51f of this example is provided over the entire length of the front end of the right panel 51c. Different from this example, the right front wall portion 51f may be provided on a part of the front end of the right panel 51c. As shown in FIG. 5, the right front wall portion 51f is in contact with the right surface 931 of the bottom portion 93a of the right vertical side portion 93 in the rain gutter member 9 described later. The right front wall portion 51f of this example is integrally formed with the upper front wall portion 51d. Different from this example, the right front wall portion 51f may be separate from the upper front wall portion 51d. When the front cover member 51 is disposed on the upper surface 31 of the loading platform 3, the front cover member 51 can be moved downward from above while the right front wall portion 51f and the left front wall portion 51e are attached to the right surface 931 of the bottom portion 93a of the right vertical side portion 93 and the left surface of the bottom portion of the left vertical side portion 92 of the rain gutter member 9. Therefore, since the front cover member 51 is less likely to be displaced during the assembly process, it is easy to dispose the front cover member 51 at a predetermined position.

[0020] (Rear cover member) As shown in Fig. 1, the rear cover member 52 is disposed behind the loading platform 3 with respect to the front cover member 51. The rear cover member 52 has a roof panel 52a, a left panel 52b, and a right panel 52c.

[0021] The roof panel 52a is disposed upward so as to face the upper surface 31 of the loading platform 3. The left panel 52b and the right panel 52c extend downward from the left edge and the right edge of the roof panel 52a. The left panel 52b and the right panel 52c are integrally formed with the roof panel 52a. At least one of the left panel 52b and the right panel 52c may be provided with a door 52d that is openable and closable so as to be accessible to the inside of the cargo box 4. In this example, doors 52d are provided on both the left panel 52b and the right panel 52c.

[0022] The rear cover member 52 of this example is provided so as to be slidable along the front and rear of the loading platform 3 with respect to a frame 71 described later. Slide rollers 53 that are slidable with respect to slide rails 73 described later are provided on the inner surfaces of the left panel 52b and the right panel 52c of the rear cover member 52 of this example. The number of slide rollers 53 in this example is four. The four slide rollers 53 are fixed near the upper end and the lower end of the inner surface of the left panel 52b of the rear cover member 52, and near the upper end and the lower end of the inner surface of the right panel 52c. Each slide roller 53 is provided so as to extend along the front and rear.

[0023] When the rear cover member 52 slides forward, as shown by the two-dot chain lines in FIGS. 1, 4, and 5, the front ends of the roof panel 52a and the right panel 52c of the rear cover member 52 abut against the rear ends of the roof panel 51a and the right panel 51c of the front cover member 51, respectively. Although not shown, the front end of the left panel 52b of the rear cover member 52 also abuts against the rear end of the left panel 51b of the front cover member 51. Although not shown, a weather strip is disposed at the abutting portion between the front cover member 51 and the rear cover member 52. By this weather strip, when the rear cover member 52 is closed, the intrusion of rainwater or the like into the interior of the luggage compartment box 4 is suppressed.

[0024] As shown by the solid line in FIG. 1, the rear cover member 52 may have two leg members 54 that support the rear of the rear cover when the rear cover member 52 slides rearward. The two leg members 54 are provided so as to be vertically movable. Each leg member 54 is configured to be fixable at a predetermined length. Each leg member 54 is raised and lowered by, for example, an air cylinder. The two leg members 54 are disposed on each of the inner surfaces of the left panel 52b and the right panel 52c.

The back door 6 of this example is pivotally connected to the trailing edge of the roof panel 52a. That is, the back door 6 of this example is an upward-opening door. Different from this example, the back door 6 may be pivotally connected to the left panel 52b or the right panel 52c so as to be openable and closable. In this case, the back door 6 is a side-opening door. Different from this example, the back door 6 may be pivotally connected to each of the left panel 52b and the right panel 52c so as to be openable and closable. In this case, the back door 6 is a double-opening door.

The right vertical frame portion 71k connects the vicinity of the lower end of the right front pillar portion 71b and the vicinity of the lower end of the right rear pillar portion 71e.

[0028] (Base plate) Each base plate 72 fixes the frame 71 to the loading platform 3. Each base plate 72 is arranged along the front and rear directions respectively on the left and right sides of the upper surface 31 of the loading platform 3. In this example, the cross-sectional shape of each base plate 72 cut by a plane orthogonal to the direction along the front and rear is L-shaped. Each base plate 72 has a horizontal plate and a vertical plate. The horizontal plate and the vertical plate are integrally formed. Each horizontal plate is fixed to the upper surface 31 of the loading platform 3. Each vertical plate projects upward from the inner end of each horizontal plate. The left front column portion 71a and the left rear column portion 71d are fixed to the right surface of the left vertical plate. The left vertical frame portion 71j may also be fixed to this right surface. The right front column portion 71b and the right rear column portion 71e are fixed to the left surface of the right vertical plate. The right vertical frame portion 71k may also be fixed to this left surface. The slide rails 73 are fixed to the left surface of the left vertical plate and the right surface of the right vertical plate.

[0029] (Slide rail) Each of the four slide rails 73 slides each of the four slide rollers 53. Each slide rail 73 is provided so as to extend along the front and rear directions. The four slide rails 73 and the four slide rollers 53 constitute a slide mechanism that supports the rear cover member 52 slidably along the front and rear of the loading platform 3 with respect to the frame 71. Each of the four slide rails 73 is fixed to the left surface of the left vertical plate, the right surface of the right vertical plate, the left surface of the left beam portion 71g, and the right surface of the right beam portion 71h. In this example, the lower ends of the left front column portion 71a, the right front column portion 71b, the left rear column portion 71d, and the right rear column portion 71e, each slide rail 73, and each vertical plate are clamped together.

[0030] [Guard frame] The guard frame 8 is disposed at the upper part of the rear surface of the back panel 21 so as to protect the rear window 21a. The guard frame 8 is fastened to the rear surface of the back panel 21 by brackets (not shown). The guard frame 8 in this example is a frame body formed by combining an upper horizontal side portion 81, a lower horizontal side portion 82, a left vertical side portion 83, a right vertical side portion 84, and an inner vertical side portion 85 as shown in FIG. 3. The upper horizontal side portion 81 in this example is composed of a hollow cylindrical body. The upper horizontal side portion 81 is disposed between the upper front wall portion 51d and the front beam portion 71c as shown in FIGS. 2 and 4. The upper horizontal side portion 81 and the upper front wall portion 51d are fixed to each other, and the upper horizontal side portion 81 and the front beam portion 71c are fixed to each other. In this example, the upper front wall portion 51d, the upper horizontal side portion 81, and the front beam portion 71c are fastened together by bolts 100. The bolts 100 are tightened by nuts 101. Different from this example, the upper front wall portion 51d, the upper horizontal side portion 81, and the front beam portion 71c may be fixed by resin clips. The left vertical side portion 83 and the left front wall portion 51e are fixed to each other, and the right vertical side portion 84 and the right front wall portion 51f are fixed to each other.

[0031] [Gutter member] The gutter member 9 drains rainwater and the like transmitted from the roof panel 22 of the passenger compartment 2 and the like outward in the vehicle width direction. The gutter member 9 is joined to the back panel 21 by welding, for example. The welding is, for example, plug welding, arc welding, or spot welding. As shown in FIG. 3, the shape of the gutter member 9 viewed from the rear of the vehicle is U-shaped with an opening downward. The gutter member 9 has an upper horizontal side portion 91, a left vertical side portion 92, and a right vertical side portion 93.

[0032] The upper horizontal side portion 91 is disposed slightly below the upper horizontal side portion 81 of the guard frame 8. In this example, the cross-sectional shape of the upper horizontal side portion 91 cut by a plane orthogonal to the direction along the left and right is U-shaped and opens upward. As shown in FIG. 4, the upper horizontal side portion 91 is composed of a bottom portion 91a, a front wall portion 91b protruding upward from the front end of the bottom portion 91a, and a rear wall portion 91c protruding upward from the rear end of the bottom portion 91a. The abutting portion 511 is abutted against the upper surface 911 of the bottom portion 91a of the upper horizontal side portion 91. The left vertical side portion 92 and the right vertical side portion 93 extend downward from the left and right edges of the upper horizontal side portion 91. The left vertical side portion 92 and the right vertical side portion 93 are integrally formed with the upper horizontal side portion 91. The configuration of the left vertical side portion 92 is the same as that of the right vertical side portion 93. The following description will be made only for the right vertical side portion 93. As shown in FIG. 5, the cross-sectional shape of the right vertical side portion 93 cut by a plane orthogonal to the direction along the up and down is U-shaped and opens outward in the vehicle width direction, that is, to the right. The right vertical side portion 93 is composed of a bottom portion 93a, a front wall portion 93b protruding to the right from the front end of the bottom portion 93a, and a rear wall portion 93c protruding to the right from the rear end of the bottom portion 93a. Although not shown, the cross-sectional shape of the left vertical side portion 92 cut by a plane orthogonal to the direction along the up and down is U-shaped and opens outward in the vehicle width direction, that is, to the left. The left vertical side portion 92 is composed of a bottom portion, a front wall portion protruding to the left from the front end of the bottom portion, and a rear wall portion protruding to the left from the rear end of the bottom portion.

[0033] Unlike this example, the cross-sectional shape of at least one of the upper horizontal side portion 91, the left vertical side portion 92, and the right vertical side portion 93 may be L-shaped. In this case, at least one side portion is composed of a bottom portion and a rear wall portion. At least one side portion is joined to the rear surface of the back panel 21 so as to form a U-shaped opening upward or outward with the rear surface of at least one side portion and the back panel 21.

[0034] The vehicle structure 1 has its respective members assembled as follows. The rain gutter member 9 is fixed to the rear surface of the back panel 21. The engaging portion 511 of the upper front wall portion 51d in the front cover member 51 is brought into contact with the upper surface 911 of the bottom portion 91a of the upper horizontal side portion 91 in the rain gutter member 9. With the engaging portion 511 and the upper surface 911 in contact, the upper front wall portion 51d, the upper horizontal side portion 81 of the guard frame 8, and the front beam portion 71c of the frame 71 are clamped together by bolts 100 and nuts 101. Through this process, the front cover member 51, the guard frame 8, and the frame 71 are assembled to each other. The vehicle structure 1 can align the mutual fixing positions between the upper front wall portion 51d and the upper horizontal side portion 81, and the mutual fixing positions between the upper horizontal side portion 81 and the front beam portion 71c by the contact between the engaging portion 511 and the upper surface 911. In this example, the through holes through which the bolts 100 are inserted in the upper front wall portion 51d, the upper horizontal side portion 81, and the front beam portion 71c can be aligned with each other. Therefore, since the vehicle structure 1 is excellent in the assembling workability of the front cover member 51, the guard frame 8, and the frame 71, the front cover member 51 and the frame 71 can be easily attached to the loading platform 3. Consequently, the vehicle structure 1 can easily attach the luggage compartment box 4 to the loading platform 3. Since the vehicle structure 1 can utilize the existing rain gutter member 9 and guard frame 8 to attach the front cover member 51 and the frame 71 to the loading platform 3, the front cover member 51 and the frame 71, and thus the luggage compartment box 4, can be retrofitted easily and inexpensively to the loading platform 3. Therefore, the vehicle structure 1 is excellent in productivity. The guard frame 8 generally has high rigidity. Since the front cover member 51 and the frame 71 are fixed to the guard frame 8 with high rigidity in the vehicle structure 1, the front cover member 51 and the frame 71 can be firmly attached to the loading platform. Therefore, the vehicle structure 1 can firmly attach the luggage compartment box 4 to the loading platform 3.

[0035] The present invention is not limited to these examples, is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0036] For example, the front cover member may not have an upper front wall portion, and the front beam portion of the frame may have a portion disposed inside the upper horizontal side portion of the rain gutter member. In this case, the front beam portion has a contact portion that is brought into contact with the upper surface of the bottom of the upper horizontal side portion. Then, the front beam portion and the upper horizontal side portion of the guard frame may be fixed to each other.

[0037] For example, the cover member may be configured as a single unit instead of being composed of a front cover member and a rear cover member that are independent of each other. In this case, the cover member is not slidable and is fixed to the loading platform. In this case, the cover member can be retrofitted to the loading platform.
