Description

[Technical Field]

[0001] Disclosed herein is a vehicle fender structure. [Background technology]

[0002] Patent Document 1 discloses a fender for a vehicle. The fender is made of resin. Compared to a fender made of metal, a resin fender is lighter. Therefore, by using a resin fender, the weight of the vehicle can be reduced.

[0003] In Patent Document 2, functional parts such as energy absorbing members are attached to the rear side of a plastic fender.

[0004] In Non-Patent Document 1, an air duct is provided at the rear end of the fender. The air in the wheelhouse is discharged to the rear of the vehicle by the air duct. In other words, the air duct suppresses an increase in air pressure in the wheelhouse. As a result, a decrease in downforce on the vehicle is suppressed. [Prior art documents] [Patent documents]

[0007] The fender panel is located close to the door panel. A gap is provided between the door panel and the fender panel to prevent interference between them when the door is opened or closed. By shortening (thinning) this gap, the elaborate assembly structure can be incorporated into the vehicle exterior.

[0008] Resin fender panels have a higher coefficient of thermal expansion than metal fender panels. For example, the linear expansion coefficient of ABS resin is more than twice that of steel. Considering the thermal expansion of resin materials, it is difficult to reduce the gap between the fender panel and the door panel while preventing interference when the door is opened and closed.

[0009] Therefore, this specification discloses a vehicle fender structure that can reduce the gap between the door panel and the resin fender panel more than ever before. [Means for solving the problem]

[0010] This specification discloses a fender structure for a vehicle. The fender structure includes a fender panel and a tubular body. The fender panel is made of resin. The fender panel is adjacent to a side door of the vehicle in the longitudinal direction of the vehicle. The tubular body is disposed inward in the vehicle width direction from the fender panel. The tubular body extends in the longitudinal direction of the vehicle. The tubular body further includes an opening. The opening faces the side door. A tubular end of the tubular body surrounding the opening is joined to the end of the fender panel on the side door side.

[0011] According to the above-described configuration, the end of the resin fender panel on the side door side is restrained by the cylindrical body, thereby suppressing deformation of the end due to heat.

[0012] In the above configuration, the opening of the cylindrical body may be positioned outward in the vehicle width direction from an outer surface of the door outer panel of the side door. In this case, the fender panel has an edge on the side door side. The door outer panel has an edge on the fender panel side. The positions of these edges in the vehicle fore-and-aft direction are aligned.

[0013] According to the above configuration, the edge of the fender panel and the edge of the door outer panel are offset in the vehicle width direction. This reduces interference between the fender panel and the door outer panel due to thermal deformation. In this configuration, aligning the edge of the fender panel and the edge of the door outer panel in the vehicle fore-and-aft direction improves the design of the vehicle's exterior.

[0014] In the above configuration, the side door may be a front door. The fender panel may be disposed in front of the front door. An upstream opening is formed at the upstream end of the cylindrical body. The upstream opening faces the wheelhouse. The bottom surface of the cylindrical body slopes upward from the upstream side to the downstream side.

[0015] Water that is stirred up inside the wheelhouse may flow into the cylindrical body. In this case, the upwardly sloping bottom of the cylindrical body prevents the water from moving forward, thereby preventing water from adhering to the front door.

[0016] In the above configuration, the downstream opening of the cylindrical body may have an opening width along the vehicle width direction that varies along the vehicle up-down direction. In this case, the straightening vane is disposed at the downstream opening of the cylindrical body at a location with the largest opening width.

[0017] According to the above configuration, the opening shape is maintained by the rectifying plate.

[0018] In the above configuration, the cylindrical end of the cylindrical body and the end of the fender panel may be joined together by adhesive tape.

[0019] According to the above configuration, the end of the fender panel is continuously restrained by the cylindrical end of the cylindrical body, compared to when the clips are fastened at intervals.

[0020] This specification also discloses a vehicle fender structure. The fender structure includes a vehicle side door, a fender panel, and a tubular body. The side door has a metal outer panel. The fender panel is made of resin. The fender panel is provided adjacent to either the side door in the front-to-rear direction of the vehicle. The tubular body is disposed on the inner side of the fender panel in the vehicle width direction. Furthermore, the tubular body is fixed to the front and rear ends of the fender panel. An opening at the front or rear end of the tubular body is oriented in a direction along the outer surface of the side door outer panel. [Effects of the Invention]

[0021] According to the vehicle fender structure disclosed in this specification, it is possible to reduce the gap between the door panel and the resin fender panel more than ever before. [Brief explanation of the drawings]

[Figure 7] FIG. 2 is a cross-sectional view taken along line AA showing a fender structure according to a first modified example of the present embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0023] A vehicle fender structure according to this embodiment will be described below with reference to the drawings. The shapes, materials, quantities, and numerical values ​​described below are examples for the purpose of explanation. These shapes and the like can be changed as appropriate depending on the specifications of the vehicle fender structure. Furthermore, the same reference numerals will be used to designate equivalent elements in all of the drawings below.

[0024] In addition, in Figures 1 to 7, a Cartesian coordinate system consisting of the FR axis, RW axis, and UP axis is used to represent the position and direction of each component. The FR axis is the axis in the longitudinal direction of the vehicle. The RW axis is the axis in the transverse direction of the vehicle. The UP axis is the axis in the vertical direction of the vehicle. The positive direction of the FR axis is the front of the vehicle. The positive direction of the RW axis is the right side of the vehicle. The positive direction of the UP axis is upward.

[0025] 1. Overall structure 1 illustrates the right side of the vehicle 10. Based on the symmetrical structure of the vehicle 10, the left side of the vehicle 10 also has the same structure as that shown in FIG.

[0026] The vehicle 10 is, for example, an electric vehicle (BEV), or alternatively, the vehicle 10 may be an internal combustion engine vehicle or a hybrid vehicle.

[0027] The vehicle fender structure according to this embodiment includes a fender panel 20 and a tubular body. The tubular body includes a protector 40 (see FIG. 4) and an air duct 50.

[0028] Referring to FIG. 1, a fender panel 20 is provided as a panel material on the side of a vehicle 10. The fender panel 20 is, for example, a front fender panel. An engine compartment or a motor compartment is sandwiched between the left and right fender panels 20, 20. A bonnet hood 13 is disposed so as to cover the upper part of the engine compartment or the motor compartment. A headlamp 12 and a bumper panel 14 are disposed in front of the fender panel 20.

[0029] Furthermore, the front lower end of the fender panel 20 is arc-shaped. The wheel 15 is disposed below this. In other words, the lower part of the fender panel 20 forms a wheel house 19. A fender liner 85 is provided on the inside of the wheel 15 in the vehicle width direction. The outer end of the fender liner 85 in the vehicle width direction is connected to the fender panel 20.

[0030] A side door 30 is provided adjacent to the fender panel 20 in the vehicle longitudinal direction. In this embodiment, the side door 30 is provided behind the fender panel 20. In this embodiment, the side door 30 is a front door.

[0031] As will be described later, the fender panel 20 is made of resin. To suppress deformation of the fender panel 20 due to thermal expansion, the fender structure according to this embodiment includes a tubular body. The tubular body includes an air duct 50 and a protector 40 (see FIG. 4). As will be described later, a downstream opening 46 (see FIG. 6) of the tubular body is surrounded by a tubular end portion 47A. The tubular end portion 47A is joined to an end portion 21A of the fender panel 20 on the side door 30 side. For example, the tubular end portion 47A is joined to the end portion 21A with adhesive tape 62. In other words, the end portion 21A of the fender panel 20 is restrained by the tubular end portion 47A. This suppresses positional changes of the end portion 21A due to thermal expansion.

[0032] 2. Side door 1 and 2, the side door 30 is, for example, a front door. The side door 30 includes a door outer panel 32 as an outer panel. The door outer panel 32 is made of metal. For example, the door outer panel 32 is formed by pressing a metal panel.

[0033] 2, the door outer panel 32 includes an upper plate portion 31 and a side plate portion 33. The upper plate portion 31 is disposed on a horizontal plane. The side plate portion 33 extends in a substantially vertical direction. A recess 34 is formed in the center of the front portion of the side plate portion 33 in the up-down direction. In other words, the front and center portions of the side plate portions 33 in the up-down direction are recessed inward in the vehicle width direction.

[0034] A downstream opening 46 is provided to correspond to the recess 34. The downstream opening 46 faces the door outer panel 32 of the side door 30. More specifically, the downstream opening 46 faces in a direction along the outer surface of the door outer panel 32. The gas discharged from the downstream opening 46 flows along the door outer panel 32 toward the rear of the vehicle.

[0035] Fig. 6 illustrates a cross section taken along line AA in Fig. 1. Fig. 6 illustrates the rotation center C1 of the side door 30. The open state of the side door 30 is indicated by a broken line. The trajectory of the edge 32A of the door outer panel 32 is also indicated by a broken line in the shape of an arc.

[0036] An edge 32A of the door outer panel 32 on the fender panel 20 side is, for example, the leading edge of the side door 30. A gap L1 is set so that the edge 32A does not interfere with the fender panel 20 and the protector 40. The gap L1 is the distance between the main surface portion 41 of the protector 40 and the edge 32A of the door outer panel 32 in the vehicle front-to-rear direction.

[0037] As will be described later, the downstream opening 46 is positioned further outward in the vehicle width direction than the outer surface of the side door 30. Accordingly, the edge 20A of the fender panel 20 on the side door 30 side and the edge 32A of the door outer panel 32 are spaced apart in the vehicle width direction. In other words, they are positioned to avoid interference between them. Therefore, the edge 20A of the fender panel 20 and the edge 32A of the door outer panel 32 are aligned in the vehicle fore-and-aft direction. In other words, the edge 20A of the fender panel 20 and the edge 32A of the door outer panel 32 are positioned in the vehicle fore-and-aft direction.

[0038] When the vehicle is viewed from the side, the visual effect is such that there is no gap between the edge 20A of the side door 30 and the edge 32A of the door outer panel 32. In other words, the elaborate assembly structure of the fender panel 20 and the side door 30 is included in the vehicle exterior appearance.

[0039] 3. Fender panel 1, the fender panel 20 is a panel component for forming a wheel arch. The fender panel 20 is adjacent to a side door 30 on either side in the vehicle front-rear direction. In this embodiment, the side door 30 is provided behind the fender panel 20. In this example, the side door 30 is a front door.

[0040] The fender panel 20 is, for example, a front fender panel. That is, the fender panel 20 is disposed in front of the side door 30. The fender panel 20 is made of resin. For example, the fender panel 20 is primarily made of polypropylene.

[0041] 2 and 3, fender panel 20 includes a side plate portion 21 and an upper plate portion 22. The lower portion of side plate portion 21 is arc-shaped. A fender molding 16 (see FIG. 1), which is a decorative part, is attached to this arc portion. Furthermore, a mudguard 17 is attached to the lower end portion of fender panel 20.

[0042] 3, flanges 23, 24 are formed on side plate portion 21. Flanges 23, 24 are disposed on the inner side in the vehicle width direction compared to the outer surface (exposed surface) of side plate portion 21. Fender molding 16 (see FIG. 1) is attached to flange 23. Mudguard 17 is attached to flange 24.

[0043] 5, a further flange 25 is formed at the front end of flange 23. Flange 25 extends inward in the vehicle width direction. Flange 25 also faces forward of the vehicle. As will be described later, flange 51 of air duct 50 (see FIG. 4) is attached to flange 25.

[0044] 2, the side plate portion 21 of the fender panel 20 has, for example, a flat shape. While the side plate portion 21 has a flat shape, the side plate portion 33 of the door outer panel 32 has a recess 34. In other words, the side plate portion 21 of the fender panel 20 and the side plate portion 33 of the door outer panel 32 are spaced apart along the vehicle width direction. A downstream opening 46 of the cylindrical body (air duct 50 and protector 40) is disposed in this gap.

[0045] 6, an end portion 21A is provided on the side plate portion 21 of the fender panel 20. The end portion 21A refers to the area of ​​the fender panel 20 on the side door 30 side. That is, the end portion 21A is close to the side door 30.

[0046] The end portion 21A is joined to a flange 42 of the protector 40. As will be described later, the flange 42 constitutes a cylindrical end portion 47A of the cylindrical body. That is, the end portion 21A of the fender panel 20 is joined to the cylindrical end portion 47A. This joining suppresses deformation of the end portion 21A due to thermal expansion.

[0047] 4. Protector 3 and 4, a protector 40 is provided on the inner surface of fender panel 20. Here, the inner surface of fender panel 20 refers to the surface behind the outer surface, which is the design surface. Protector 40 is made of a resin material such as polypropylene.

[0048] The protector 40 has a main surface portion 41. The main surface portion 41 is a plate-shaped portion extending in the vehicle width direction. As illustrated in FIG. 6, the main surface portion 41 faces the edge 32A of the door outer panel 32.

[0049] A downstream opening 46 is formed in the main surface portion 41. For example, the downstream opening 46 penetrates along the thickness direction of the main surface portion 41. With reference to FIGS. 3 and 5 , the downstream opening 46 is an opening region surrounded by an upper wall 46A, a lower wall 46B, and the flanges 42 and 43.

[0050] 3, the opening width of the downstream opening 46 along the vehicle width direction varies along the vehicle up-down direction. For example, the outer side of the downstream opening 46 in the vehicle width direction is formed linearly in accordance with the shape of the side plate portion 21 of the fender panel 20. On the other hand, the inner side of the downstream opening 46 in the vehicle width direction is formed in an arc shape in accordance with the shape of the side plate portion 33 of the door outer panel 32 (see FIG. 2). In other words, the downstream opening 46 has the widest width at the center portion in the up-down direction.

[0051] 5, flanges 42, 43, and 44 are formed on the main surface portion 41. All of the flanges 42, 43, and 44 extend from the main surface portion 41 toward the front of the vehicle. The flange 42 is provided at the outer end of the main surface portion 41 in the vehicle width direction. The flange 43 and the flange 42 sandwich a downstream opening 46 therebetween. The flange 44 is disposed at the inner end of the main surface portion 41 in the vehicle width direction.

[0052] 2 and 6, the area of ​​the main surface portion 41 between the flanges 43 and 44 is hidden by the side door 30 (door outer panel 32). A clip hole 41A is drilled between the flanges 43 and 44. The downstream opening 46 is disposed outward in the vehicle width direction from the outer surface of the side door 30 (door outer panel 32).

[0053] 6, clip 90 is inserted into clip hole 41A. Clip 90 fastens main surface portion 41 and bracket 74. The inner side of bracket 74 in the vehicle width direction is fixed to A-pillar 70. For example, the inner side of bracket 74 in the vehicle width direction is welded to A-pillar outer panel 72.

[0054] 5, for example, main surface portion 41 extends from upper plate portion 22 of fender panel 20 to flange 24. Similarly, flanges 42, 43, and 44 also extend from upper plate portion 22 of fender panel 20 to flange 24. Referring to FIG. 6, flange 42 is joined to end portion 21A of side plate portion 21 via adhesive tape 62. In other words, end portion 21A of fender panel 20 is restrained by flange 42 over the entire area in the up-down direction. This restraining structure suppresses deformation of end portion 21A due to thermal expansion.

[0055] 5, a plurality of straightening vanes 45 are provided between the flanges 42, 43. The straightening vanes 45 extend horizontally, for example, along the front-rear direction of the vehicle. The plurality of straightening vanes 45 are arranged in the downstream opening 46 at intervals along the up-down direction of the vehicle.

[0056] As described above, the opening width of the downstream opening 46 along the vehicle width direction varies along the vehicle up-down direction. Therefore, the width dimensions of the plurality of straightening vanes 45 also vary. For example, the straightening vane 45A is disposed at the downstream opening 46 at a location where the opening width is greatest. This arrangement suppresses deformation of the downstream opening 46.

[0057] The plurality of straightening vanes 45 arranged in the vertical direction include an uppermost straightening vane 45B and a lowermost straightening vane 45C. These straightening vanes 45B and 45C and the flanges 42 and 43 form a cylindrical structure. This cylindrical structure is connected to the rear end of the air duct 50 (see FIG. 4). The straightening vane 45B corresponds to the upper wall 46A in FIG. 3. The straightening vane 45C corresponds to the lower wall 46B in FIG. 3.

[0058] 4 and 6, the flange 43 is joined to a flange 55 of the air duct 50. For example, the flanges 43 and 55 are joined together via an adhesive tape 64.

[0059] 6, a sealant 60 is sandwiched between the flange 44 and the A-pillar outer member 72. For example, the sealant 60 having a predetermined thickness is sandwiched between the flange 44 and the A-pillar outer member 72 in a crushed state. This prevents water from entering from the motor compartment 80.

[0060] 5. Air duct 1 and 4, air duct 50 is disposed inward in the vehicle width direction from fender panel 20. Air duct 50 is a square pipe with a rectangular cross section. An upstream opening 52 is provided at the front end of air duct 50. Upstream opening 52 is aligned with opening 85A of fender liner 85. In other words, air inside wheelhouse 19 flows into air duct 50 from upstream opening 52.

[0061] The air duct 50 has a flange 51 formed around the upstream opening 52. Referring to FIG. 6, the flange 51 is fastened to the fender liner 85 by a clip 91.

[0062] A connecting opening 54 is formed at the rear end of the air duct 50. The connecting opening 54 is aligned with the downstream opening 46 of the protector 40.

[0063] The air duct 50 is provided with a flange 55. The flange 55 extends rearward from the connection opening 54. The flange 55 is connected to the flange 43 of the protector 40. For example, as described above, the flanges 43 and 55 are connected via adhesive tape 64.

[0064] As described above, the outer flange 42 of the protector 40 is connected to the end 21A of the fender panel 20. Thus, for example, the air duct 50 is connected to the protector 40 only by the flanges 43, 55.

[0065] 1 and 4, the cross section of the air duct 50 is larger on the upstream side than on the downstream side. Furthermore, the bottom surface 53 of the air duct 50 slopes upward from the upstream side to the downstream side.

[0066] The upstream opening 52 is disposed rearward of the wheel 15. Therefore, there is a risk that water splashed up by the wheel 15 may enter the air duct 50. Here, the bottom surface 53 has an upward slope, which suppresses the advance of water. This prevents water in the air duct 50 from being discharged from the downstream opening 46. As a result, adhesion of water to the door outer panel 32 is suppressed.

[0067] 6. Cylindrical body 4 and 6, the air duct 50 and the protector 40 form a cylindrical body. That is, the air duct 50 and the protector 40 form a cylindrical body that communicates from the upstream opening 52 of the air duct 50, via the connecting opening 54, to the downstream opening 46. In other words, the upstream opening 52 is formed at the upstream end of the cylindrical body. The downstream opening 46 is formed at the downstream end of the cylindrical body. This cylindrical body is disposed on the inside of the fender panel 20 in the vehicle width direction. The cylindrical body also extends in the front-to-rear direction of the vehicle. Further, referring to FIG. 6, the cylindrical body is fixed to the front and rear ends of the fender panel 20.

[0068] Because the cylindrical body is divided into the air duct 50 and the protector 40, it is possible to flexibly accommodate changes in the size of the air duct 50. For example, the distance from the wheel 15 (see FIG. 1) to the side door 30 varies depending on the vehicle model. By preparing air ducts 50 of various lengths, it is possible to accommodate changes in the distance between the wheel 15 and the side door 30 without making any changes to the protector 40.

[0069] Additionally, the front and rear ends of the fender panel 20 are joined by a cylindrical body, which suppresses thermal expansion of the fender panel 20 in the vehicle's fore-and-aft direction. As a result, even if the gap between the door outer panel 32 and the fender panel 20 is narrowed, interference between them is suppressed.

[0070] 7. Vehicle rear structure In the embodiment shown in FIGS. 1 to 6, the fender panel 20 corresponds to a front fender, and the side door 30 corresponds to a front door. Alternatively, the fender panel 20 may be a rear fender. The side door 30 may be a rear door. In this case, the fender panel 20 is disposed behind the side door 30.

[0071] For example, when the internal combustion engine is mounted in a so-called midship or rear engine configuration, the side intakes are formed in the rear fender. The rear fender may be made of resin, and the side intakes may be configured from the above-described cylindrical bodies (air duct 50 and protector 40).

[0072] In this case, the cylindrical body is disposed inward in the vehicle width direction from the fender panel 20. Furthermore, a protector 40, which is a part of the cylindrical body, is located close to the rear end of the door outer panel 32. Furthermore, an air duct 50 is connected downstream of the protector 40.

[0073] Even in this case, the flange 42 (see FIG. 6) of the protector 40 restrains the end portion 21A of the fender panel 20 in the vertical direction, thereby suppressing deformation of the end portion 21A due to thermal expansion.

[0074] 8. First Alternative Example of This Embodiment 7 shows a first alternative example of the fender structure according to this embodiment. In this example, the cylindrical body is composed only of an air duct 50. A downstream opening 46 is formed at the rear end of the air duct 50. The downstream opening 46 is surrounded by a cylindrical end portion 58.

[0075] A flange 28 is formed at the rear end of the fender panel 20. The flange 28 extends inward in the vehicle width direction from the rear end of the side plate portion 21. More specifically, the fender panel 20 is folded back from the rear end of the side plate portion 21 toward the front of the vehicle. The flange 28 extends in the vehicle width direction from this folded back portion.

[0076] A clip hole 28A is drilled in the flange 28. The flange 28 is fastened to the bracket 74 by inserting a clip 90 into the clip hole 28A.

[0077] Additionally, an opening 28B is drilled in the flange 28. The opening 28B is aligned with the downstream opening 46 of the air duct 50. A flange 59 is formed around the periphery of the downstream opening 46. The flange 59 is joined to the flange 28 of the fender panel 20. For example, the flanges 28, 59 are welded together.

[0078] Even in this structure, the end 29 of the fender panel 20 is joined to the cylindrical end 58 of the air duct 50, which is a cylindrical body. In other words, the end 29 is restrained by the air duct 50. This prevents the end 29 from deforming due to thermal expansion. [Explanation of symbols]
