Description

[Technical Field]

[0001] The present invention relates to a vehicle body structure including a metal body, a resin outer panel attached to the body, and an adjacent member attached to the body so as to be adjacent to the outer panel. [Background technology]

[0002] Patent Document 1 discloses a structure in which a positioning pin is arranged to ensure the positional accuracy of a resin garnish relative to a metal front fender panel. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-144618 Summary of the Invention [Problem to be solved by the invention]

[0004] Resin parts have greater thermal expansion than metal bodies, so when attaching resin parts to a metal body, a structure that ensures positional accuracy, such as that described in Patent Document 1, is required.

[0005] Meanwhile, in recent years, vehicle bodies with resin outer panels attached to metal bodies have been considered. Resin outer panels are larger in size than the resin garnish described in Patent Document 1, and the absolute amount of thermal expansion is greater than that of the garnish. This raises the risk of deterioration in appearance due to thermal expansion and interference with adjacent components adjacent to the outer panels.

[0006] Therefore, an object of the present disclosure is to suppress deterioration of appearance due to thermal expansion of resin outer panels and interference with other components. [Means for solving the problem]

[0007] The vehicle body of the present disclosure is a vehicle body comprising a metal body, a resin outer panel attached to the body, and an adjacent member attached to the body adjacent to the outer panel, and is characterized in that it comprises a positioning pin provided on one of the body and the outer panel, and a through hole provided on the other of the body and the outer panel through which the positioning pin is inserted, the positioning pin being arranged along the boundary line between the outer panel and the adjacent member, the horizontal gap between the through hole and the positioning pin in a direction intersecting the extension direction of the boundary line being smaller than the width of the boundary line between the outer panel and the adjacent member, and the vertical gap between the through hole and the positioning pin in the direction of extension of the boundary line being larger than the horizontal gap.

[0008] This prevents the plastic outer panel from moving in a direction intersecting the boundary line due to thermal expansion, and prevents the width of the boundary line between the panel and other components from changing. This prevents the appearance from deteriorating due to changes in the width of the boundary line, and prevents the outer panel from interfering with other components. In addition, because the vertical gap is longer than the horizontal gap, the vertical gap can absorb the thermal expansion of the outer panel.

[0009] In the vehicle body of the present disclosure, the positioning pin may be provided in the outer plate, and the insertion hole may be provided in the body or a bracket attached to the body.

[0010] This allows the positioning pin to be made by integral molding of resin, simplifying the structure.

[0011] The vehicle body of the present disclosure may include a clip attached to the outer panel and a clip insertion hole provided in the body through which the clip is inserted, the clip being arranged along the boundary line between the outer panel and the adjacent member, the horizontal clip gap between the clip insertion hole and the direction intersecting the extension direction of the boundary line of the clip being smaller than the width of the boundary line between the outer panel and the adjacent member, and the vertical clip gap between the clip insertion hole and the direction in which the boundary line of the clip is extended being larger than the horizontal clip gap.

[0012] As a result, the clip and the clip insertion hole can effectively prevent the resin outer panel from moving in a direction intersecting the boundary line.

[0013] In the vehicle body of the present disclosure, the positioning pins and the clips may be arranged alternately along the boundary line.

[0014] This makes it possible to more effectively prevent the resin outer panel from moving in a direction intersecting the boundary line.

[0015] In the vehicle of the present disclosure, the outer panel is a decorative panel provided on the side of the body, the adjacent member is a door attached to the body, the decorative panel and the door are arranged side by side in the fore-and-aft direction of the vehicle, the horizontal gap and the horizontal clip gap are gaps in the fore-and-aft direction of the vehicle, the vertical gap and the vertical clip gap are gaps in the up-and-down direction of the vehicle, and the insertion hole and the clip insertion hole may be long holes extending in the up-and-down direction of the vehicle.

[0016] This prevents the width of the gap between the decorative panel and the door from changing, which can lead to a poor appearance, and prevents the decorative panel from interfering with the door and affecting the door's opening and closing function. [Effects of the Invention]

[0017] The present disclosure can suppress deterioration of appearance due to thermal expansion of resin outer panels and interference with adjacent components. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0019] A vehicle body 100 according to an embodiment will now be described with reference to the drawings. FIG. 1 is a right side view of a vehicle 200 equipped with the vehicle body 100 according to the embodiment. As shown in FIG. 1, the vehicle 200 includes the vehicle body 100 and a rear wheel 70. The vehicle body 100 includes a body 10, a quarter panel 30 attached to the body 10, and a door 50 attached to the body 10 adjacent to the quarter panel 30. The quarter panel 30 and the door 50 are separated by a boundary line 60 having a width E (see FIG. 4). Here, the quarter panel 30 is an outer panel attached to the body 10. The door 50 is an adjacent member adjacent to the quarter panel 30. Note that FR, UP, and RH shown in each drawing indicate the front, upper, and right sides of the vehicle 200, respectively. The opposite directions of FR, UP, and RH indicate the rear, lower, and left sides. Hereinafter, when simply using the directions of front / rear, left / right, and up / down, unless otherwise specified, these directions refer to the front / rear direction of the vehicle 200, the left / right direction of the left / right, and the up / down direction of the up / down direction of the vehicle 200. Furthermore, the front / rear, left / right, and up / down directions of the vehicle 200 are the front / rear, left / right, and up / down directions of the vehicle body 100.

[0020] 2, the body 10 includes rockers 11, roof rails 12, center pillars 13, rear pillars 16, and rear side panels 17. The body 10 is made of metal.

[0021] The rocker 11 is a skeletal member disposed at the bottom of the vehicle body 100 and extending in the longitudinal direction of the vehicle. The roof rail 12 is a skeletal member disposed at the top of the vehicle body 100 and extending in the longitudinal direction of the vehicle. The center pillar 13 is a skeletal member that vertically connects the rocker 11 and the roof rail 12 at the center of the longitudinal direction of the vehicle body 100. The rear pillar 16 vertically connects the rocker 11 and the roof rail 12 at the rear of the vehicle body 100. The rear pillar 16 is a skeletal member with a closed cross section that is composed of a plate-shaped inner panel 14 and an outer panel 15 that is a channel-shaped cross section member (see Figure 4). The rear side panel 17 is a rear portion of the rear pillar 16 and forms the rear side of the body 10. The rocker 11, roof rail 12, center pillar 13, and rear pillar 16 define a door opening 18.

[0022] As shown in FIG. 2, four clip insertion holes 23 are provided in the vertical center of the outer panel 15. The clip insertion holes 23 are elongated holes extending in the vertical direction of the vehicle. Shanks 42 of clips 40, which will be described later, are inserted into the clip insertion holes 23. Three brackets 21 are attached to the vertical center of the outer panel 15. As shown in FIG. 4, the brackets 21 are plate members attached to the rear flange 15R of the outer panel 15, extending toward the front right of the vehicle, and having their front ends bent parallel to the bottom plate 15A of the outer panel 15. Insertion holes 22 are provided in the front ends of the brackets 21. The insertion holes 22 are elongated holes extending in the vertical direction of the vehicle. Positioning pins 36 of the quarter panel 30, which will be described later, are inserted into the insertion holes 22. As shown in FIG. 2, the brackets 21 are attached to the outer panel 15 so that the clip insertion holes 23 and the insertion holes 22 are alternately arranged in the vertical direction.

[0023] In addition, the rear side panel 17 of the body 10 has multiple clip insertion holes 23 in addition to the four clip insertion holes 23 described with reference to Figure 2, but the illustration and description of the other clip insertion holes 23 will be omitted.

[0024] Figure 3 shows the inner surface of the quarter panel 30 attached to the outside of the rear side panel 17. The quarter panel 30 is a resin design panel whose outer surface forms the design surface of the side of the vehicle body 100. As shown in Figure 3, the quarter panel 30 includes a main body 31, a step portion 32, an attachment base 33, an end plate 34, a clip base 35, and a positioning pin 36. The main body 31, the step portion 32, the attachment base 33, the end plate 34, the clip base 35, and the positioning pin 36 are integrally molded from resin.

[0025] As shown in FIG. 4 , the main body 31 covers the outside of the rear side panel 17, and its outer surface constitutes the design surface of the side of the vehicle body 100. The step portion 32 is a stepped portion provided in the front of the main body 31 and extending from the main body 31 toward the inside of the vehicle. The mounting base 33 is a plate member connected to the vehicle-inside end of the step portion 32. As shown in FIG. 3 , the mounting base 33 is curved so as to protrude toward the rear of the vehicle and face the bottom plate 15A of the outer panel 15. The end plate 34 is erected from the mounting base 33 toward the inside of the vehicle. Returning to FIG. 4 , the end plate 34 extends from the mounting base 33 toward the bottom plate 15A of the outer panel 15 and is arranged to continue to the door opening 18. The clip base 35 is an L-shaped cross-sectional member protruding toward the inside of the vehicle from the mounting base 33. A clip mounting hole 35B is provided in the inner flange 35A on the inside of the vehicle. A clip 40 is attached to the clip mounting hole 35B. The positioning pins 36 are round bar members that protrude toward the inside of the vehicle from the mounting base 33. As shown in Fig. 3, the clip seats 35 and the positioning pins 36 are arranged alternately in the vertical direction of the vehicle.

[0026] As shown in Figure 4, clip 40 is composed of head 41, shank 42, fixing ring 43, and locking portion 44. Shank 42 of clip 40 is inserted into clip attachment hole 35B from the outside of inner flange 35A. Fixing ring 43 is fitted onto shank 42 protruding inside inner flange 35A. Fixing ring 43 and head 41 sandwich inner flange 35A from both sides, fixing clip 40 to inner flange 35A.

[0027] As shown in Fig. 3, the quarter panel 30 with the clip 40 fixed to the clip base 35 is turned over, the locking portion 44 of the clip 40 is pushed into the clip insertion hole 23 shown in Fig. 2, and the positioning pin 36 is inserted into the insertion hole 22 of the bracket 21. Then, as shown in Fig. 4, when the locking portion 44 is caused to protrude inside the inner flange 35A, the locking portion 44 opens and engages with the inner surface of the inner flange 35A. This attaches the quarter panel 30 to the outside of the rear side panel 17. When the quarter panel 30 is attached to the rear side panel 17, the positioning pin 36 is inserted into the insertion hole 22.

[0028] As shown in FIG. 4, when the door 50 is attached to the body 10, a gap of width E is formed at a boundary line 60 between the front end of the main body 31 of the quarter panel 30 and the rear end of the resin panel 51 of the door 50.

[0029] As shown in FIG. 5 , the insertion hole 22 and the clip insertion hole 23 are elongated holes extending in the vehicle up-down direction. A gap is provided between the positioning pin 36 and the insertion hole 22. A lateral gap S1 between the positioning pin 36 and the insertion hole 22 in the vehicle longitudinal direction is smaller than the width E of the boundary line 60. A vertical gap S2 between the positioning pin 36 and the insertion hole 22 in the vehicle up-down direction is larger than the lateral gap S1. Similarly, a gap is provided between the shank 42 of the clip 40 and the clip insertion hole 23. A lateral clip gap S3 between the shank 42 and the clip insertion hole 23 in the vehicle up-down direction is smaller than the width E of the boundary line 60. A vertical clip gap S4 between the shank 42 and the clip insertion hole 23 in the vehicle up-down direction is larger than the lateral clip gap S3. Here, the horizontal gap S1 and the horizontal clip gap S3 are gaps in a direction intersecting the boundary line 60, and the vertical gap S2 and the vertical clip gap S4 are gaps in the direction in which the boundary line 60 extends.

[0030] When the temperature of the vehicle body 100 configured as described above rises, the resin quarter panel 30 thermally expands more than the metal body 10. At this time, the insertion hole 22 and the clip insertion hole 23, which are elongated holes extending in the vertical direction, allow the positioning pin 36 and the shaft 42 of the clip 40 to move vertically relative to the body 10 due to thermal expansion. This allows the thermal expansion of the resin quarter panel 30 to be absorbed. Meanwhile, the insertion hole 22 and the clip insertion hole 23 restrict the amount of movement of the positioning pin 36 and the shaft 42 in the fore-and-aft direction of the vehicle to be smaller than the width E of the gap at the boundary line 60. This prevents the quarter panel 30 from advancing toward the resin panel 51 of the door 50 and interfering with the resin panel 51. This also prevents the quarter panel 30 from advancing toward the resin panel 51 of the door 50, significantly changing the width E of the gap at the boundary line 60 and degrading the appearance of the vehicle 200.

[0031] Furthermore, the main body 31, step portion 32, mounting base 33, end plate 34, clip base 35, and positioning pin 36 are integrally molded from resin, so that interference between the quarter panel 30 and the resin panel 51 can be prevented with a simple configuration.

[0032] Furthermore, the insertion holes 22 and clip insertion holes 23, and the positioning pins 36 and clips 40, which are alternately arranged in the vertical direction of the vehicle, can effectively prevent the width E of the boundary line 60 between the quarter panel 30 and the door 50 from changing. This effectively prevents the appearance of the vehicle body 100 from changing due to a change in the width E of the boundary line 60.

[0033] In the above description, the bracket 21 is attached to the outer panel 15 so that the clip insertion holes 23 and the insertion holes 22 are alternately arranged in the up-down direction, and the clip bases 35 and the positioning pins 36 are alternately arranged in the up-down direction of the vehicle. However, this is not limiting. For example, the bracket 21 may be attached to the outer panel 15 so that the clip insertion holes 23 and the insertion holes 22 are alternately arranged along the boundary line 60, and the clip bases 35 and the positioning pins 36 may be alternately arranged along the boundary line 60. The clip insertion holes 23 and the insertion holes 22 may be elongated holes that are long in a direction inclined with respect to the up-down direction of the boundary line 60. In this case, the lateral gap S1 and the lateral clip gap S3 may be gaps that are perpendicular to the boundary line 60 and are smaller than the width E of the boundary line 60. Furthermore, the vertical gap S2 and the vertical clip gap S4 may be gaps that are inclined with respect to the up-down direction of the boundary line 60 and are larger than the lateral gap S1 and the lateral clip gap S3, respectively.

[0034] In the above description, the positioning pin 36 is provided in the quarter panel 30, and the insertion hole 22 is provided in the bracket 21 attached to the rear pillar 16. However, this is not limiting. For example, the insertion hole 22 may be provided in the outer panel 15 of the rear pillar 16. Alternatively, the positioning pin 36 may be attached to the bracket 21 of the rear pillar 16, and the insertion hole 22 may be provided in the mounting base 33 of the quarter panel 30. Alternatively, the positioning pin 36 may be attached to the outer panel 15 of the rear pillar 16, and the insertion hole 22 may be provided in the mounting base 33 of the quarter panel 30.

[0035] In the above description, the vehicle body 100 of the embodiment is described as attaching the quarter panel 30 to the vehicle body 10 using the insertion holes 22 and the positioning pins 36, and the clip insertion holes 23 and the clips 40, thereby suppressing interference between the quarter panel 30 and the door 50 and changes in the width E of the boundary line 60. However, this is not limited to this. For example, the insertion holes 22 and the clip insertion holes 23 may be arranged along the boundary line between the front door and a resin fender panel covering a metal fender at the front of the vehicle, thereby suppressing interference between the fender panel and the front door and changes in the width of the boundary line. As another example, the insertion holes 22 and the clip insertion holes 23 may be arranged along the boundary line between the resin fender panel covering the metal fender at the front of the vehicle and a resin hood, thereby suppressing interference between the fender panel and the hood and changes in the width of the boundary line. In this case, the boundary line extends in the vehicle fore-and-aft direction, and the lateral gap S1 and the lateral clip gap S3 are gaps in the vehicle width direction, and the vertical gap S2 and the vertical clip gap S4 are gaps in the vehicle fore-and-aft direction. As another example, the insertion holes 22 and clip insertion holes 23 may be arranged along the boundary between the roof side panel covering the outer surface of the metal roof rail 12 and the plastic roof panel that forms the roof, thereby suppressing interference between the roof side panel and the plastic roof panel and changes in the width of the boundary line. In this case, the boundary line extends in the fore-and-aft direction of the vehicle, the lateral gap S1 and the lateral clip gap S3 are gaps in the vehicle width direction, and the vertical gap S2 and the vertical clip gap S4 are gaps in the fore-and-aft direction of the vehicle.
