Description

Body structure

[0001] This case relates to a vehicle body structure equipped with a fender shield.

[0002] Conventionally, there has been known a structure for mounting an on-board device to a vehicle using a mounting bracket to mount the on-board device in a vehicle compartment (such as an engine compartment, a motor compartment, or a power unit compartment). For example, a structure has been known in which a bracket is fixed to a dash panel or a frame that constitutes part of the compartment, and the on-board device (such as a fuel filter) is supported by the bracket (see Patent Document 1).

[0003] Japanese Patent Application Laid-Open No. 2006-132362

[0004] On the other hand, when the vehicle is subjected to some kind of external force, the shape of the accommodation compartment itself may deform, causing the position of the bracket fixed to the dash panel or frame to move. In this case, the in-vehicle device may move to follow the deformation of the accommodation compartment itself, which may cause interference with other devices or the vehicle body structure located nearby. Therefore, it is desirable to realize a new structure that can improve the protection performance of the in-vehicle device.

[0005] One of the objectives of the present invention, which was devised in light of the above-mentioned problems, is to provide a vehicle body structure that can improve the protection performance of an on-vehicle device. However, in addition to this objective, another objective of the present invention is to achieve effects derived from the configurations shown in the "Description of Embodiments" below, which cannot be obtained with conventional technologies.

[0006] The disclosed vehicle body structure can be realized as the following disclosed embodiments (application examples), which solve at least part of the above-mentioned problems. Each of the embodiments from embodiment 2 onwards is an embodiment that can be selected as an additional option, and each of the embodiments can be omitted. None of the embodiments from embodiment 2 onwards discloses an embodiment or configuration that is essential to the present invention.

[0007] Aspect 1. The disclosed vehicle body structure includes a fender shield that is provided inside a fender panel of a vehicle and forms part of the bottom surface of a compartment that accommodates an on-vehicle device.

Aspect 5. In any of the above-mentioned Aspects 1 to 4, it is preferable that the third surface portion has a first reinforcing portion that bulges in the plate thickness direction around a portion where the second on-board device is fixed.

[0010] Aspect 6. In Aspect 4 above, it is preferable that the third surface portion has a first reinforcing portion formed by bulging in the plate thickness direction around a portion where the second on-board device is fixed, and that the first reinforcing portion is located to the side of the second vertical wall portion. Aspect 7. In Aspect 4 above, it is preferable that the fender shield has a second reinforcing portion formed by the first vertical wall portion and the second vertical wall portion, and that has a flat top portion and an upwardly bulging shape. It is also preferable that a strut tower is disposed in the second reinforcing portion.

[0011] Aspect 8. In any of Aspects 1 to 7 above, it is preferable that a tray member be provided that is attached substantially horizontally to the first surface portion, the first on-vehicle device be fixed to the first surface portion via the tray member, and the tray member have a tray bead formed by a portion of a plate surface that bulges in a plate thickness direction and extends in the front-to-rear direction of the vehicle.

[0012] Aspect 9. In any of Aspects 1 to 8 described above, it is preferable that the vehicle includes a pair of left and right upper frames supporting both left and right end edges of a bonnet hood, and a pair of left and right front subframes extending from a front end of each upper frame toward the inside of the vehicle and toward a front-downward direction and connected to a front support member, wherein a front end of the first surface portion is joined to the front subframes, and a side end of the third surface portion is joined to the upper frame.

[0013] Aspect 10.

[0014] According to the disclosed vehicle body structure, when the fender shield is deformed by an external force from the front side of the storage compartment, a mountain-folding deformation can be promoted in the second surface portion between the first surface portion, the third surface portion, and the ridge line portion of the fender shield, which can reduce interference between the on-board device and other surrounding devices or the vehicle body structure, thereby improving the protection performance of the on-board device.

[0015] Fig. 1 is a perspective view showing an exploded and partially see-through state of a vehicle body structure according to an embodiment. Fig. 2 is a longitudinal sectional view showing the structure of the storage compartment shown in Fig. 1. Fig. 3 is an exploded perspective view showing the structure around the left fender shield. (A) is a top view of the left fender shield, and (B) is a side view thereof.

[0016] The disclosed vehicle body structure is applied to a vehicle shown in the following embodiment. This vehicle body structure includes a fender shield. The fender shield is provided inside the fender panel of the vehicle and forms part of the bottom surface of a storage compartment that houses on-board equipment. The storage compartment referred to here includes, for example, an engine compartment, a motor compartment, a power unit compartment, etc. The on-board equipment referred to here also includes drive-related devices (fuel filters, fuel pumps, canisters, air cleaners, various reservoir tanks, brake boosters, transformers, batteries, etc.) and other devices (air conditioning-related devices, electrical equipment, etc.).

[0017] Regarding the definition of directions in this embodiment, the front-rear direction (vehicle length direction) is defined based on the forward and backward direction of the vehicle, and the left-right direction (vehicle width direction) is defined based on the front-rear direction. The up-down direction is defined based on the state in which the vehicle is stopped on a flat road surface. Note that, regarding the vehicle width direction, in the portion to the left of the vehicle body centerline in a top view of the vehicle, the left is the outer side of the vehicle and the right is the inner side of the vehicle. Also, in the portion to the right of the vehicle body centerline in a top view of the vehicle, the right is the outer side of the vehicle and the left is the inner side of the vehicle.

[0018] [1. Storage compartment] Fig. 1 is an exploded perspective view showing a partially see-through state of a storage compartment 1 of a vehicle to which a vehicle body structure according to an embodiment is applied, and Fig. 2 is a vertical cross-sectional view of the storage compartment 1. The storage compartment 1 in this embodiment is a power unit room that houses a drive unit of the vehicle, and is located in the front of the passenger compartment where occupants board.

[0019] 1 and 2 accommodates an engine (internal combustion engine as a drive unit), a first on-vehicle device 11 (battery), and a second on-vehicle device 12 (fuel filter), all of which are not shown. An opening is provided at the upper end of the accommodation chamber 1, and a bonnet hood, not shown, is attached to this opening so as to be able to open and close. The engine is located inside the accommodation chamber 1, for example, in a position from near the center to the right side in the vehicle width direction.

[0020] The first on-vehicle device 11 is a secondary battery (so-called auxiliary battery) that stores electricity generated by an alternator (not shown) that is attached to the engine, and is disposed on the left side (left of the engine) inside the accommodation compartment 1. The second on-vehicle device 12 is a filter device that filters fuel supplied to the engine, and is disposed on the left side (left of the engine) inside the accommodation compartment 1, rearward of the first on-vehicle device 11. The first on-vehicle device 11 and the second on-vehicle device 12 are fixed to the fender shield 10, which will be described later. The first on-vehicle device 11 and the second on-vehicle device 12 may also be disposed in a different position (for example, to the right of the engine).

[0021] A pair of left and right side members 2 are disposed below the accommodation compartment 1. The side members 2 are one of the frame members provided to extend in the front-to-rear direction and are provided at a predetermined interval in the left-to-right direction. A front bumper beam 4 is connected to the front end of each side member 2. The front bumper beam 4 is a protective member that absorbs impact when an external force is input from the front of the vehicle, and is provided approximately horizontally so as to extend outward in the vehicle width direction beyond the left and right side members 2.

[0022] A front support member 3 (radiator core support member) is connected to the front portion of each side member 2 at a position slightly rearward of the front bumper beam 4. The front support member 3 is a member that extends in the vertical direction and has the function of supporting the radiator unit and headlamp unit that are attached to the front end of the vehicle. A pair of front support members 3 are provided at the front end of the accommodation chamber 1, spaced a predetermined distance apart in the left-right direction.

[0023] The upper ends of the left and right front support members 3 are connected substantially horizontally by an upper bar 6. The upper bar 6 is a member for supporting the front end of the bonnet hood, and is disposed, for example, along the edge of the opening to which the bonnet hood is attached. The left and right ends of the upper bar 6 extend outward in the vehicle width direction beyond the front support members 3 and extend toward the rear of the vehicle in a curve that follows the shape of the left and right sides of the bonnet hood. The upper frame 5 is connected to both ends of the upper bar 6.

[0024] The upper frame 5 is a member that extends substantially horizontally forward from near the lower end of the vehicle's front pillar and is connected to both ends of the upper bar 6. A pair of upper frames 5 are arranged on the left and right sides above the accommodation compartment 1. The vehicle's front fender panels are attached to the outside of the upper frames 5. In addition, front wheel tires and strut towers 13 (not shown) are arranged below the upper frames 5. The upper frames 5 and upper bar 6 function to support the portions of the bonnet hood from both left and right edges to the front edge. The strut towers 13 are tower-shaped portions to which the upper parts of the struts (springs and dampers) of the suspension device are fixed. The lower ends of the strut towers 13 are fixed to the side members 2.

[0025] In addition to the upper bar 6, a front subframe 7 is also connected to the front end of the upper frame 5. The front subframe 7 is provided to extend downward and inward toward the front of the vehicle from the connection point between the upper frame 5 and the upper bar 6, and is a member connected to the front support member 3. The front subframe 7 has a function of supporting the headlamp unit. The upper bar 6 and the front subframe 7 are arranged to branch out from the front end of the upper frame 5 and extend forward, with the headlamp unit disposed between them.

[0026] A dash panel 8 is provided at the rear end of the accommodation compartment 1. The dash panel 8 is a planar member that divides the vehicle interior and the accommodation compartment 1 in the front-to-rear direction, and the space forward of the dash panel 8 forms the accommodation compartment 1. The dash panel 8 is erected to cover the rear end of the accommodation compartment 1, for example, from the upper end surface of the upper frame 5 to the upper end surface of the side member 2. The lower end of the dash panel 8 is provided to extend rearward in a planar manner along, for example, the upper end surface of the side member 2, and is connected to the floor panel of the vehicle interior so as to be substantially flush with the floor panel.

[0027] As shown in Figure 2, a first cross member 9 is provided forward of the joint between the front support member 3 and the front subframe 7. The first cross member 9 is a member that has a hat-shaped cross section and extends in the vehicle width direction, and connects the pair of left and right front support members 3 in the vehicle width direction. The orientation of the first cross member 9 is set so that the top surface of the hat-shaped cross section faces the front of the vehicle and the flange portion of the hat-shaped cross section is in surface contact with the front side of the front support member 3.

[0028] A fender shield 10 is attached to the interior of the accommodation compartment 1. The fender shield 10 is a planar member that is located inside the vehicle fender panel and forms part of the bottom surface of the accommodation compartment 1. As shown in FIG. 1 , a pair of fender shields 10 in this embodiment are provided on the inside of each of the left and right fender panels. An outer edge of the fender shield 10 on the vehicle side is connected to the upper frame 5 and the front subframe 7. An inner edge of the fender shield 10 on the vehicle side is provided so as to be spaced above the side member 2.

[0029] As shown in Figure 2, a strut tower 13 and a wheelhouse are disposed below the fender shield 10. The overall shape of the fender shield 10 is such that it does not interfere with the wheelhouse, and is arched in shape with the center portion bulging slightly upward relative to the front end in a side view. A first vehicle-mounted device 11 and a second vehicle-mounted device 12 are fixed to the top of the left fender shield 10. The fender shield 10 on the side to which the first vehicle-mounted device 11 and the second vehicle-mounted device 12 are not fixed (the right side in this embodiment) can be omitted.

[0030] [2. Fender Shield] Figure 3 is an exploded perspective view showing the structure around the left fender shield 10, Figure 4(A) is a top view of the left fender shield 10, and Figure 4(B) is a side view thereof. The left fender shield 10 has at least a first surface portion 21, a second surface portion 22, a third surface portion 23, and a ridge portion 41. In this embodiment, a fourth surface portion 24 is provided in addition to these. The fourth surface portion 24 is an optional portion.

[0031] The first surface portion 21 is a planar portion that forms the front end portion of the fender shield 10, and is formed as a surface that slopes downward toward the front side. The first on-board device 11 is disposed on the first surface portion 21. The surface shape of the first surface portion 21 may be curved or flat. A front end portion of the first surface portion 21 is joined to the front subframe 7, and a left end portion of the first surface portion 21 is joined to the upper frame 5 and the front subframe 7.

[0032] Preferably, the front end of the first surface portion 21 is joined to the front support member 3 and the front subframe 7 so that the front end of the first surface portion 21 is located immediately behind the first cross member 9 in a side view. In other words, the position in the height direction of the front end of the first surface portion 21, which is fixed to the rear surfaces of the front support member 3 and the front subframe 7, is set to the same height as the first cross member 9, which is fixed to the front surface of the front support member 3 and the front subframe 7.

[0033] 4A, a reinforcing bead 25 is formed on the first surface portion 21. The bead 25 is a portion formed by extending a portion of the plate surface in the longitudinal direction of the vehicle, the portion being bulged in the thickness direction of the plate. The bead 25 in this embodiment is formed in a shape in which a plurality of linear portions bulging downward from the surrounding area are arranged at intervals in the vehicle width direction.

[0034] The second surface portion 22 is a planar portion formed in a substantially flat band shape that extends in the vehicle width direction rearward of the first surface portion 21. A left end portion of the second surface portion 22 is joined to the upper frame 5. With regard to the bending rigidity of the fender shield 10, the bending rigidity of the second surface portion 22 is set to be smaller than that of the first surface portion 21 and also smaller than that of a third surface portion 23, which will be described later. The second surface portion 22 is more easily bent than the first surface portion 21 and the third surface portion 23, and constitutes a portion that will become a ridge of mountain-folding deformation when subjected to an external force from the front side of the storage compartment 1 (for example, part or all of the second surface portion 22 is bent and deformed into an upwardly convex shape).

[0035] The ridge line portion 41 is a portion including a wall portion formed by bulging the plate surface in the plate thickness direction on the rear side of the second surface portion 22. The ridge line portion 41 has a first vertical wall portion 31 extending in the vehicle width direction and a second vertical wall portion 32 extending in the front-to-rear direction. The first vertical wall portion 31 is a portion that constitutes the front portion of the wall portion of the ridge line portion 41, and the second vertical wall portion 32 is a portion that constitutes the right portion of the wall portion of the ridge line portion 41, and has a shape that extends rearward from the inner end of the first vertical wall portion 31 in the vehicle width direction. The overall shape of the ridge line portion 41 in a top view is L-shaped.

[0036] The first vertical wall portion 31 is formed in a surface shape that slopes upward toward the rear side of the second surface portion 22 (a slope that slopes downward toward the front side). The boundary portion between the first vertical wall portion 31 and the second surface portion 22 has a valley-folded shape that convex downward (a shape that forms an upside-down ridge line). The second vertical wall portion 32 is formed in a surface shape that slopes upward toward the outside in the vehicle width direction (a slope that slopes downward toward the right side). The boundary portion between the second vertical wall portion 32 and a third surface portion 23 (described later) also has a valley-folded shape that convex downward (a shape that forms an upside-down ridge line).

[0037] The third surface portion 23 is a planar portion on which the second in-vehicle device 12 is disposed, rearward of the second surface portion 22 and approximately to the side of the ridge portion 41. The left end of the third surface portion 23 is joined to the upper frame 5. As shown in FIGS. 4A and 4B , the third surface portion 23 is provided with a first reinforcing portion 51 (in-vehicle device reinforcing portion). The first reinforcing portion 51 is a portion formed by bulging in the plate thickness direction around the location where the second in-vehicle device 12 is fixed, and is formed, for example, in a rectangular shape bulging downward from the surrounding area. The first reinforcing portion 51 is located to the side of the second vertical wall portion 32.

[0038] A second reinforcement portion 52 (strut tower reinforcement portion) is provided outward (to the left) of the first reinforcement portion 51 in the vehicle width direction. The second reinforcement portion 52 is a portion formed by bulging upward around the area where the strut tower 13 is located. The second reinforcement portion 52 is formed by a first vertical wall portion 31 and a second vertical wall portion 32, and has a flat top portion (flat portion 30). The flat portion 30 is formed in a substantially horizontal plane so as to face the top surface of the strut tower 13. The first vertical wall portion 31 is located to the right (inner in the vehicle width direction) of the flat portion 30, and the second vertical wall portion 32 is located forward of the flat portion 30. The first vertical wall portion 31 forms an inclined surface connecting the flat portion 30 and the second surface portion 22, and the second vertical wall portion 32 forms an inclined surface connecting the flat portion 30 and the first reinforcement portion 51.

[0039] The fourth surface portion 24 is a planar portion located rearward of the third surface portion 23. The fourth surface portion 24 is formed, for example, as a surface that slopes downward toward the rear (toward the center in the vehicle's longitudinal direction). The rear end of the fourth surface portion 24 is joined to the dash panel 8, and the left end of the fourth surface portion 24 is joined to the upper frame 5. The fourth surface portion 24 may also be formed in a substantially horizontal shape so as to be flush with the third surface portion 23.

[0040] As shown in Fig. 3 , the first in-vehicle device 11 is fixed to the first surface 21 of this embodiment via a tray member 28. The tray member 28 is a bracket member for fixing the first in-vehicle device 11, and is attached approximately horizontally to the first surface 21. The tray member 28 shown in Fig. 3 has a horizontal surface portion that is an approximately horizontal surface on which the first in-vehicle device 11 is placed and a wall portion that extends downward from the front end edge of the horizontal surface, and has a substantially L-shaped vertical cross section. The tray member 28 may be fixed to the first surface 21 using a bracket (not shown), or may be fixed by a fastener (not shown), or may be fixed by welding.

[0041] The tray member 28 is positioned so as to overlap the bead 25 in a top view. This improves the stability of the first in-vehicle device 11. In addition, a tray bead 29 is formed on the tray member 28. The tray bead 29 is a portion formed by extending a portion of the plate surface that bulges in the plate thickness direction in the longitudinal direction of the vehicle. The tray bead 29 in this embodiment is formed in a shape in which multiple linear portions that bulge downward from the surrounding area are arranged at intervals in the vehicle width direction.

[0042] [3. Effects] (1) The vehicle body structure according to this embodiment includes a fender shield 10 having a first surface 21, a second surface 22, a ridge line 41, and a third surface 23. The first surface 21 is formed as a surface that slopes downward toward the front, and a first on-vehicle device 11 is disposed on the first surface 21. The second surface 22 is formed as a substantially flat band extending in the vehicle width direction behind the first surface 21. The ridge line 41 is disposed behind the second surface 22 and includes wall portions (first vertical wall portion 31, second vertical wall portion 32) formed by bulging the plate surface in the plate thickness direction. The third surface 23 is disposed behind the second surface 22 and substantially to the side of the ridge line 41, and a second on-vehicle device 12 is fixed thereto.

[0043] With this configuration, when the fender shield 10 is deformed by an external force from the front side of the storage compartment 1, mountain-folding deformation can be promoted in the second surface portion 22 between the first surface portion 21, the third surface portion 23, and the ridge portion 41. In other words, by bending the fender shield 10 in front of the second on-vehicle device 12, the front of the second on-vehicle device 12 is covered by the fender shield 10, making it difficult for the first on-vehicle device 11 or the vehicle body structure to approach the second on-vehicle device 12 from the front side. This reduces interference between the second on-vehicle device 12 and other surrounding devices and vehicle body structure, and improves the protection performance of the on-vehicle devices (e.g., the first on-vehicle device 11, the second on-vehicle device 12) stored in the storage compartment 1.

[0044] (2) The first surface portion 21 has a bead 25 formed by extending a portion of the plate surface bulging in the thickness direction in the front-rear direction. This increases the bending rigidity of the first surface portion 21 and relatively reduces the bending rigidity of the second surface portion 22. This promotes mountain-folding deformation in the second surface portion 22 when subjected to an external force from the front, further improving the protection performance of the in-vehicle device accommodated in the accommodation chamber 1. Furthermore, by shaping the bead 25 so that it bulges downward from the surrounding area, it is possible to prevent interference between the bead 25 and the tray member 28 or the first in-vehicle device 11 attached to the first surface portion 21, thereby increasing the degree of freedom in the layout of the first in-vehicle device 11 inside the accommodation chamber 1.

[0045] (3) The ridgeline portion 41 is provided with a first vertical wall portion 31 that forms an upwardly sloping surface toward the rear side of the second surface portion 22 and extends along the vehicle width direction. This increases the bending rigidity of the rear side of the second surface portion 22 and promotes mountain-folding deformation of the second surface portion 22 against an external force from the front side of the storage compartment 1. This further improves the protection performance of the on-vehicle devices stored in the storage compartment 1. In addition, by forming the first vertical wall portion 31 into a surface that slopes upwardly toward the rear side of the second surface portion 22, it becomes easier to ensure installation space for the strut tower 13 below the fender shield 10, as shown in FIG. 2 . This improves the protection performance of the storage compartment 1 without impairing the operation or performance of the vehicle suspension system.

[0046] (4) The ridgeline portion 41 is provided with a second vertical wall portion 32 that extends rearward from the inner end of the first vertical wall portion 31 in the vehicle width direction and is formed as a surface that slopes upward toward the outer side in the vehicle width direction. This further increases the bending rigidity of the rear side of the second surface portion 22. In particular, the second vertical wall portion 32 is shaped to receive loads in the fore-and-aft direction within its surface, making it less likely to deform due to external forces from the front side and more likely to maintain its shape. This makes it relatively easier for bending deformation to occur in the second surface portion 22 forward of the second vertical wall portion 32. This further improves the protection performance of the on-vehicle device accommodated in the accommodation chamber 1. Furthermore, by shaping the second vertical wall portion 32 as a surface that slopes upward toward the outer side in the vehicle width direction, it becomes easier to ensure installation space for the strut tower 13 below the fender shield 10. This improves the protection performance of the accommodation chamber 1 without impairing the operation or performance of the vehicle suspension system.

[0047] (5) The third surface portion 23 has a first reinforcing portion 51 formed by bulging in the thickness direction around the portion where the second in-vehicle device 12 is fixed. This increases the bending rigidity of the third surface portion 23 and relatively reduces the bending rigidity of the second surface portion 22. This promotes mountain-folding deformation of the second surface portion 22 when an external force is applied from the front side, further improving the protection performance of the in-vehicle device accommodated in the accommodation chamber 1.

[0048] Furthermore, by forming the first reinforcing portion 51 so that it bulges downward relative to the surrounding area, the mounting position of the second in-vehicle device 12 in the height direction can be lowered. As a result, when the second surface portion 22 is subjected to a mountain-folding deformation due to an external force from the front, the second in-vehicle device 12 is likely to be positioned below the ridge of the mountain-folded second surface portion 22. Therefore, interference between the second in-vehicle device 12 and other surrounding devices and vehicle body structure can be more reliably suppressed, and the protective performance of the second in-vehicle device 12 can be further improved.

[0049] (6) The first reinforcing portion 51 is disposed on the side of the second vertical wall portion 32. By providing the first reinforcing portion 51 on the side of the portion with high bending rigidity (the second vertical wall portion 32), the mounting state of the second in-vehicle device 12 can be stabilized. Furthermore, even if the second surface portion 22 is subjected to a mountain fold deformation due to an external force from the front side, the surface shape of the first reinforcing portion 51 is likely to be maintained. This makes it possible to prevent the second in-vehicle device 12 from moving to an unintended position or changing its posture in an unintended direction. Therefore, the protection performance of the second in-vehicle device 12 can be further improved.

[0050] (7) The fender shield 10 described above includes a second reinforcing portion 52. The second reinforcing portion 52 is formed by the first vertical wall portion 31 and the second vertical wall portion 32, and has a flat top portion and an upwardly bulging shape. As shown in FIG. 2 , the strut tower 13 is disposed below the second reinforcing portion 52. This increases the bending rigidity around the strut tower 13, promoting bending deformation near the boundary between the second vertical wall portion 32 and the second surface portion 22 located in front of it, and facilitating mountain-folding deformation at the second surface portion 22. This further improves the protection performance of the on-vehicle equipment accommodated in the accommodation compartment 1.

[0051] (8) The fender shield 10 described above includes a tray member 28. The tray member 28 is attached substantially horizontally to the first surface 21. The first in-vehicle device 11 is fixed to the first surface 21 via the tray member 28. The tray member 28 also has a tray bead 29 formed by a portion of the plate surface that bulges in the plate thickness direction and extends in the front-to-rear direction. By fixing the first in-vehicle device 11 to the first surface 21 forward of the second surface 22 in this manner, interference between the second in-vehicle device 12 and the first in-vehicle device 11 can be prevented when an external force is applied from the front, and the protection performance of the second in-vehicle device 12 can be further improved.

[0052] The first in-vehicle device 11 is indirectly fixed to the first surface 21 of the fender shield 10 via the tray member 28. As a result, even if the first surface 21 is slightly deformed due to an external force, the deformation is less likely to affect the first in-vehicle device 11, preventing deformation and damage to the first in-vehicle device 11. In this sense as well, the protection performance of the first in-vehicle device 11 can be improved.

[0053] (9) The vehicle of this embodiment includes a pair of left and right upper frames 5 that support both left and right end edges of the bonnet hood, and a pair of left and right front subframes 7 that extend from front ends of the upper frames 5 toward the inside of the vehicle and toward the front and downward direction and are connected to the front support member 3. Furthermore, a front end of the first surface portion 21 is joined to the front subframes 7, and a side end of the third surface portion 23 is joined to the upper frames 5.

[0054] This configuration ensures the bending rigidity of the fender shield 10 when no external force is applied, while easily achieving mountain-folding deformation when an external force is applied. Also, by joining the front end of the first panel 21 to the front subframe 7, the attachment state of the first on-vehicle device 11 fixed to the first panel 21 can be stabilized, preventing wobbling of the first on-vehicle device 11 while the vehicle is traveling, for example.

[0055] (10) The vehicle of this embodiment includes a first cross member 9 that has a hat-shaped cross section, extends in the vehicle width direction, and connects the pair of left and right front support members 3 in the vehicle width direction. The front end of the first surface portion 21 is set to the same height as the first cross member 9. This makes it easier for a bending moment to act on the second surface portion 22 when an external force acts from the front of the vehicle, promoting mountain-folding deformation in the second surface portion 22. This further improves the protection performance of the on-board devices housed in the accommodation compartment 1.

[0056] [4. Other] The above-described embodiments are merely illustrative and are not intended to exclude various modifications or applications of techniques not explicitly described in the present embodiments. Each configuration of the present embodiments can be modified in various ways without departing from the spirit of the present embodiments. Furthermore, each configuration of the present embodiments can be selected as needed, or can be appropriately combined with various configurations included in known techniques.

[0057] In the above embodiment, a structure in which the first in-vehicle device 11 is fixed to the first surface 21 of the fender shield 10 via the tray member 28 has been exemplified, but the first in-vehicle device 11 may also be attached directly to the first surface 21. By providing at least the second surface 22 between the first surface 21 on which the first in-vehicle device 11 is disposed and the third surface 23 on which the second in-vehicle device 12 is disposed, and by providing a ridge portion 41 on the rear side of the second surface 22, a structure that provides the same effects as the above embodiment can be realized.

[0058] The present invention is applicable to the vehicle manufacturing industry in which a body structure equipped with a fender shield is applied.
