Description

Vehicle hood

The present invention relates to a vehicle hood in which a reinforcing member is deployed between an outer panel and an inner panel.

Conventionally, in a vehicle hood that covers the upper surface of a vehicle compartment (engine room, motor room, etc.), a structure in which a reinforcing member is inserted between an outer panel and an inner panel is known. For example, a structure has been proposed in which an arch-shaped bracket is fixed to the inner panel and the plate surface of the bracket is expanded along the back surface of the outer panel (see Patent Document 1). Further, a structure in which a plate-shaped reinforcing member is attached to the back surface of the outer panel to increase the rigidity has also been proposed (see Patent Document 2).

JP 2006-306237 JP JP 2016-010995

Energies when external force is applied to the vehicle hood are absorbed by the deformation of the outer panel and the reinforcing member. Therefore, if the deformed shape can be controlled, the cushioning performance can be improved. On the other hand, existing vehicle hoods cannot be said to have sufficiently taken these points into consideration, and there is room for improvement. For example, by devising a structure for fixing the reinforcing member to the inner panel, further improvement in cushioning performance is expected.

One of the objectives of this case was created in view of the above problems, and is to improve the cushioning performance by controlling the deformed shape of the reinforcing member of the vehicle hood. It should be noted that the present invention is not limited to this purpose, and it is also possible to obtain operational effects that are derived from the respective configurations described in “Modes for Carrying Out the Invention” that will be described later and that cannot be obtained by conventional techniques. Can be positioned as a purpose.

The disclosed vehicle hood is a vehicle hood in which a reinforcing member is deployed between the outer panel and the inner panel. This vehicle hood includes a front surface portion that is a front portion of the reinforcing member and that reinforces a front end portion of the vehicle. The front surface portion has a planar rear surface portion that extends from the left and right ends of the front surface portion toward the rear of the vehicle and outward in the vehicle width direction. Further, a rear leg portion is provided extending from the vehicle outer side edge of the rear surface portion toward the front of the vehicle and fixed to the inner panel.

Extending the rear legs toward the front of the vehicle from the vehicle outer edge of the rear surface makes it easier to secure the length from the base to the tip without increasing the size in the vehicle width direction. As a result, the stroke of deformation of the reinforcing member can be increased, and the cushioning performance of the vehicle hood can be improved.

[1. Vehicle hood structure]
A vehicle hood 10 as an embodiment will be described with reference to FIGS. 1 to 7. The vehicle hood 10 is a member that covers the upper surface of a compartment (an in-vehicle product accommodating room such as an engine room or a motor room) provided in the front part of the vehicle. Near the rear end of the compartment, a hinge that pivotally supports the vehicle hood 10 with respect to the vehicle body and a spring that urges the vehicle hood 10 in the opening direction are provided. Further, in the vicinity of the front end portion of the compartment, a hood lock device for maintaining the closed state of the vehicle hood 10 and a support rod used for holding the open state are provided.

As shown in FIG. 1, a vehicle hood 10 has a structure in which a reinforcement member 3 (hood lock reinforcement upper) is deployed between an outer panel 1 (hood outer panel) and an inner panel 2 (hood inner panel). To have. The outer panel 1 is a member that forms the outer surface of the vehicular hood 10, and the front side plate surface is subjected to design painting or uneven processing. Further, the front portion of the outer panel 1 is provided with a grill reinforcing portion 11 having an opening through which the cooling air introduced into the compartment passes. The grill 12 of the vehicle is attached to the grill reinforcing portion 11. The headlamp 13 of the vehicle is attached to the vehicle body in front of the compartment. The position of the headlamp 13 is set to the left and right sides of the grill 12 when the vehicle hood 10 is closed.

The inner panel 2 is arranged below the outer panel 1 with a predetermined space therebetween, and is joined to the outer edge portion of the outer panel 1. The plate surface of the inner panel 2 is provided with irregularities for increasing strength and rigidity. The inner panel 2 of the present embodiment is provided with the edge portion 14 and the beam portion 15. The edge portion 14 is a substantially horizontal portion formed along the edges of the left and right ends of the inner panel 2 and functions as a flange for reinforcement. The beam portion 15 is a portion where the plate surface is dented downward and the dents are connected along the inner side of the edge portion 14 in the vehicle front-rear direction, and functions as a structural cross section for increasing the bending rigidity of the inner panel 2. ..

The reinforcing member 3 is arranged in a plane shape along the plate surface of the outer panel 1 in the space surrounded by the outer panel 1 and the inner panel 2. The material of the reinforcing member 3 is an aluminum alloy (for example, Al-Mg-based alloy or Al-Mg-Si-based alloy) and is formed by processing a rolled plate. The reinforcing member 3 is fixed to the outer panel 1 and the inner panel 2. For example, the reinforcing member 3 of the present embodiment is fixed to the outer panel 1 with a mastic adhesive and fixed to the inner panel 2 by welding.

⑦ The overall shape of the reinforcing member 3 in a top view of the vehicle is similar to the boomerang shape curved in a bow, and the layout is such that the vicinity of the central portion in the vehicle width direction projects to the front of the vehicle. Further, the shape of the reinforcing member 3 is left-right symmetric (mirror symmetry) in a top view of the vehicle. As shown in FIG. 2, the reinforcing member 3 of the present embodiment has a front surface portion 4 and a pair of rear surface portions 5. The front surface portion 4 is a half-moon-shaped portion of the reinforcing member 3 located at the front portion of the vehicle. The rear surface portion 5 is a portion extending rearward of the vehicle and outward in the vehicle width direction from each of the left and right end portions thereof. A boundary line between the front surface portion 4 and the rear surface portion 5 is illustrated by a chain line in FIG. However, the front surface portion 4 and the rear surface portion 5 are integrally formed, and their boundaries are merely defined for convenience.

The reinforcing member 3 is provided with three pairs of

legs

6, 7, 8 fixed to the inner panel 2. These

leg portions

6, 7, 8 extend obliquely from the reinforcing member 3 outward and downward. Hereinafter, the leg portion provided on the front surface portion 4 will be referred to as the front leg portion 6. Further, among the legs provided on the rear surface portion 5, those located outside the vehicle are referred to as rear legs 7, and those located inside the vehicle are referred to as second rear legs 8.

The front leg portion 6 is the front end portion of the front surface portion 4, and is arranged on both the left and right sides of the grill reinforcing portion 11 (positions avoiding the grill 12). The position of the front leg 6 in the top view of the vehicle is a position corresponding to the back side of the headlamp 13, as shown in FIG. The front end of the front leg portion 6 is fixed in a state of being in surface contact with the edge portion 14 of the inner panel 2, for example, spot welding. The direction in which the front leg portion 6 extends from the front surface portion 4 in a top view of the vehicle is obliquely forward (the direction toward the outside and front of the vehicle).

A flange 16 bent downward is formed on a portion of the front end side of the front surface portion 4 sandwiched between the left and right front leg portions 6. However, the left and right ends of the flange 16 are interrupted before reaching the front leg 6. The flange 16 is not formed at a portion of the front end side of the front surface portion 4 adjacent to the front leg portion 6 on the vehicle center side. On the other hand, a second flange 17 is formed at a portion outside the vehicle adjacent to the front leg portion 6. The second flange 17 is a portion formed by bending the left and right side edges of the front surface portion 4 downward, and is provided so as to be connected to the plate surface of the front leg portion 6. The rear end portion of the second flange 17 is interrupted before reaching the rear surface portion 5.

The rear leg section 7 and the second rear leg section 8 are extended from the rear surface section 5. The rear leg portion 7 is arranged at a position closer to the rear of the vehicle (closer to the end portion) than the outer side edge of the vehicle on the rear surface portion 5. On the other hand, the second rear leg portion 8 is arranged at a position closer to the rear of the vehicle (closer to the end portion) than the inner end side of the vehicle of the rear surface portion 5. Roughly speaking, the positions of the rear leg portion 7 and the second rear leg portion 8 are set at positions corresponding to the left and right ends (two tips) in the boomerang shape. Further, the rear leg portion 7 is arranged outside the boomerang shape, and the second rear leg portion 8 is arranged inside the boomerang shape.

The direction in which the second rear leg portion 8 extends from the rear surface portion 5 in the top view of the vehicle is the direction opposite to the front leg portion 6 and is diagonally rearward (direction toward the inside and rear of the vehicle). Further, the direction in which the rear leg portion 7 extends from the rear surface portion 5 is the front of the vehicle. As a result, the distance from the base end to the tip of the rear leg portion 7 becomes long, and the deformation stroke becomes large when an external force is applied. Further, as compared with the case where the rear leg portion 7 is extended outward in the vehicle width direction, the protrusion of the rear leg portion 7 in the vehicle width direction is suppressed.

The tips of the rear legs 7 are fixed (for example, spot welded) in surface contact with the edge 14 of the inner panel 2. On the other hand, the tip of the second rear leg portion 8 is fixed in a state of surface contact with the plate surface of the inner panel 2, and is fixed by spot welding, for example. Further, as shown in FIG. 2, the second flange 17 is not formed on the vehicle outer side edge of the rear surface portion 5. That is, the bending deformation is allowed by not applying the reinforcing structure for increasing the second moment of area near the boundary between the rear surface portion 5 and the rear leg portion 7.

A staircase flange 18 formed in a staircase shape is provided on the rear end side of the front surface portion 4 and the vehicle inner end side of the rear surface portion 5. The staircase flange 18 is a portion in which the plate surfaces of the front surface portion 4 and the rear surface portion 5 are bent in a crank shape downward and rearward of the vehicle, and is formed so as to be connected to the plate surface of the second rear leg portion 8. It As a result, the entire range corresponding to the inner side of the boomerang shape of the end side of the reinforcing member 3 has a structure in which bending deformation is difficult.

[2. Structure of hind legs]
The rear leg portion 7 extends in a planar shape from the edge portion of the rear surface portion 5 of the reinforcing member 3 and is fixed to the edge portion 14 of the inner panel 2. As described above, the rear leg portion 7 is arranged at a position closer to the rear side of the vehicle (closer to the end portion) than the outer side edge of the rear surface portion 5 of the vehicle, and extends toward the front of the vehicle. Similar to the front leg portion 6, the rear leg portion 7 can be formed by press working the end portion of the plate surface of the reinforcing member 3. As shown in FIGS. 3 to 6, the rear leg portion 7 is provided with the rear leg first surface portion 40, the rear leg second surface portion 41, and the rear leg third surface portion 42 in this order from the top.

The rear leg first surface portion 40 (first surface portion) is a planar portion provided on the uppermost portion of the rear leg portion 7. The rear leg first surface portion 40 extends from the edge of the rear surface portion 5 so as to form the same plane as the rear surface portion 5. A boundary 50 between the rear surface portion 5 and the rear leg first surface portion 40 is linear and is shown by a broken line in FIGS. 4 and 5. The boundary between the rear leg first surface portion 40 and the rear leg second surface portion 41 is arranged parallel to the boundary 50 (the vehicle outer end side of the rear surface portion 5). In other words, the shape of the rear leg first surface portion 40 is a rectangular planar shape, and the side in contact with the boundary 50 is formed to be longer than the side adjacent thereto.

The rear leg second surface portion 41 (second surface portion) is a planar portion adjacent to the rear leg first surface portion 40 and provided below the rear leg first surface portion 40. The rear leg second surface portion 41 is obliquely connected to the rear leg first surface portion 40 in an inclined direction. The rough shape of the rear leg second surface portion 41 can be similar to a parallelogram shape extending toward the front of the vehicle. At least the boundary between the rear leg second surface portion 41 and the rear leg third surface portion 42 is arranged parallel to the boundary between the rear leg first surface portion 40 and the rear leg second surface portion 41. By forming the width of the base end side (the rear leg first surface portion 40 side) narrower than that of the tip end side (the rear leg third surface portion 42 side), the easiness of deformation of the rear leg second surface portion 41 is improved. You may let me.

As shown in FIG. 4, the third bent portion 43 that forms the boundary between the rear leg first surface portion 40 and the rear leg second surface portion 41 is a ridge line of a mountain fold (a fold line that is convex upward). As shown in FIG. 6(B), the bending angle θ ₄ of the rear leg second surface portion 41 with respect to the rear leg first surface portion 40 is set to an angle shallower than at least a right angle (for example, 10 to 80°). Since the third bent portion 43 is displaced to a position (outside the vehicle) away from the boundary 50, bending deformation at the boundary 50 is relatively likely to be induced when an external force is applied.

The rear leg third surface portion 42 (third surface portion) is a planar portion provided adjacent to the rear leg second surface portion 41 and below the rear leg second surface portion 41. The rear leg third surface portion 42 is obliquely connected to the rear leg first surface portion 40 in an inclined direction, but the bending direction of the rear leg third surface portion 42 with respect to the rear leg second surface portion 41 is The bending direction of the rear leg second surface portion 41 with respect to the first surface portion 40 is set in the opposite direction. As a result, the fourth bent portion 44 that forms the boundary between the rear leg second surface portion 41 and the rear leg third surface portion 42 becomes a valley-folded groove (folded downwardly).

In the present embodiment, the bending angle θ ₅ of the rear leg third surface portion 42 with respect to the rear leg second surface portion 41 is an angle shallower than a right angle and is the same as the bending angle θ _{4 of} the rear leg second surface portion 41. Set. That is, θ ₄ = θ ₅ . The bending of the rear leg second surface portion 41 is restored by the bending of the rear leg third surface portion 42. As a result, the posture of the rear leg third surface portion 42 becomes substantially horizontal as in the rear leg first surface portion 40, and the orientation is such that the edge portion 14 of the inner panel 2 is easily surface-contacted. Further, by making the third surface portion 42 of the rear leg parallel to the rear surface portion 5, the fixed state of the reinforcing member 3 is stabilized.

As shown in FIGS. 3 to 5, a cut portion 45 is provided between the rear leg portion 7 and the rear surface portion 5. The cut portion 45 is a portion formed in a shape cut to the vehicle rear side from a position where the rear leg portion 7 and the inner panel 2 are fixed, and has a shape like a cove recessed toward the vehicle rear side in a top view. Have. Further, of the edges of the rear surface portion 5 and the rear leg portion 7, a reinforcing structure such as a flange or a bead is not applied to a portion in contact with the notch portion 45. For example, the second flange 17 does not enter the range behind the vehicle from the third surface portion 42 in top view, and is arranged only in front of the vehicle from the notch portion 45.

As shown in FIG. 6A, the third bent portion 43 is provided with a third bead 46 and a fourth bead 47. These

beads

46 and 47 are formed in a shape bulging toward the lower inner panel 2 at the boundary between the rear leg first surface portion 40 and the rear leg second surface portion 41. The shape of the

beads

46 and 47 is set to be an elliptical shape, a circular shape, an oval shape, etc. that is elongated in the lateral direction. By providing

such beads

46 and 47, the deformation of the third bent portion 43 when an external force is applied is reduced, and the bending angle θ _{4 of the} rear leg first surface portion 40 and the rear leg second surface portion 41 is easily maintained. Become.

In the present embodiment, a plurality of

beads

46 and 47 are provided at the boundary between the rear leg first surface portion 40 and the rear leg second surface portion 41. Both of these

beads

46 and 47 are arranged in the third bent portion 43. Therefore, the line connecting the two

beads

46 and 47 is parallel to the boundary 50 and the extending direction of the fourth bent portion 44. By providing the plurality of

beads

46 and 47, the deformation of the third bent portion 43 when an external force is applied is further suppressed.

The rear leg second surface portion 41 and the rear leg third surface portion 42 include a fourth reinforcing portion 48 for reinforcing an end side of the rear leg portion 7 (an end side connecting the reinforcing member 3 and the inner panel 2). A fifth reinforcing portion 49 is provided. These reinforcing

portions

48 and 49 are portions formed by bending the plate surface, and are formed along the end edges of the rear leg portions 7. The reinforcing

portions

48 and 49 of this embodiment have a shape in which the plate surfaces of the rear leg second surface portion 41 and the rear leg third surface portion 42 are raised. That is, by bending the plate surface twice, the cross-sectional shape is crank-shaped. As shown in FIG. 6(C), the cross-sectional shape of the rear leg third surface portion 42 is formed in a shape in which both left and right end portions are raised more than the central portion (upside down hat shape).

The fourth reinforcing portion 48 is provided on the first end side 51 on the outer side in the vehicle width direction among the end sides of the rear leg second surface portion 41. Further, the fourth reinforcing portion 48 is also extended to the end side of the rear leg third surface portion 42 adjacent to the first end side 51 of the rear leg second surface portion 41. The fourth reinforcing portion 48 functions to reinforce the outer side edges of the rear leg second surface portion 41 and the rear leg third surface portion 42 and suppress bending deformation near the outer side edges.

The fifth reinforcing portion 49 is provided on the end sides of the rear leg second surface portion 41 and the rear leg third surface portion 42. However, the range of the fifth reinforcing portion 49 is set such that the second end side 52 of the rear leg second surface portion 41 facing the first end side 51 hardly includes the fifth reinforcing portion 49. For example, as shown in FIG. 5, the fifth reinforcing portion 49 is provided only on a portion of the second end side 52 of the rear leg second surface portion 41 that extends linearly from the rear leg third surface portion 42. Most of the second end side 52 does not have the fifth reinforcing portion 49, that is, is a flat non-reinforcing portion in which the plate surface is not bent.

[3. Action, effect]
FIG. 7 is a diagram illustrating a deformed state of the rear leg portion 7 when an external force is applied to the outer panel 1 from above the vehicle hood 10. Since the first end side 51 of the rear leg second surface portion 41 is reinforced by the fourth reinforcing portion 48, it is difficult to deform and the posture is easily maintained. On the other hand, the notch 45 is provided between the rear leg portion 7 and the rear surface portion 5, and the second end side 52 of the rear leg second surface portion 41 hardly includes the fifth reinforcing portion 49. As a result, bending deformation on the second end side 52 side becomes easy to be allowed.

Moreover, since the third bead 46 and the fourth bead 47 are provided in the third bent portion 43, the bending angle θ _{4 of the} rear leg first surface portion 40 and the rear leg second surface portion 41 is easily maintained. As a result, as shown in FIG. 7, the vicinity of the boundary 50 is more easily bent than the third bent portion 43, and the vicinity of the boundary 50 is a valley-folded groove (folded downward convex). As a result, the third bent portion 43 moves above the rear surface portion 5, and the deformation stroke increases. Of the edges of the rear surface portion 5 and the rear leg portion 7, a reinforcing structure such as a flange or a bead is not applied to a portion in contact with the notch portion 45. Therefore, when the rear leg portion 7 is deformed, unintended interference or contact with the inner panel 2 is prevented, and the cushioning performance of the rear leg portion 7 is improved.

(1) A front surface portion 4 and a rear surface portion 5 are provided on the reinforcing member 3 of the vehicle hood 10 described above. The rear surface portion 5 is a planar portion extending rearward of the vehicle and outward in the vehicle width direction from each of the left and right end portions of the front surface portion 4. A rear leg portion 7 extends from the vehicle outer side edge of the rear surface portion 5 toward the front of the vehicle and is fixed to the inner panel 2. With such a configuration, it is possible to increase the distance from the base end to the tip end of the rear leg portion 7 while suppressing the protrusion of the rear leg portion 7 in the vehicle width direction. Therefore, it is possible to increase the deformation stroke of the rear leg portion 7 and the reinforcing member 3 when an external force is applied, and it is possible to improve the cushioning performance of the vehicle hood 10.

(2) As shown in FIGS. 3 to 5, a notch portion 45 is provided between the rear leg portion 7 and the rear surface portion 5. As a result, the rear leg portion 7 in a top view can be elongated in the vehicle front-rear direction, and a long leg having a small vehicle width direction dimension can be formed. Further, by providing the cut portion 45, the stress transmission direction in the rear leg portion 7 can be limited to the vehicle front-rear direction. As a result, the deformation stroke of the rear leg portion 7 and the reinforcing member 3 when an external force is applied can be increased, and the cushioning performance of the vehicle hood 10 can be improved.

(3) As shown in FIG. 6(B), the rear legs 7 are arranged in a posture inclined with a downward slope toward the outside of the vehicle. As a result, the plate surface of the rear leg portion 7 can be easily deformed so as to fall downward, and the controllability of the deformed shape of the reinforcing member 3 can be improved. Further, the external force input to the reinforcing member 3 can be easily dispersed outside the vehicle, and the cushioning performance of the vehicle hood 10 can be improved.

(4) As shown in FIG. 6B, the rear leg portion 7 is provided with a rear leg first surface portion 40, a rear leg second surface portion 41, and a rear leg third surface portion 42. Of these surface portions 40 to 42, only the rear leg third surface portion 42 is fixed to the inner panel 2. Further, the rear leg first surface portion 40 is provided so as to be flush with the rear surface portion 5. With such a configuration, it is possible to easily bend the vicinity of the boundary 50 when an external force is applied, and the rear leg portion 7 can be deformed as intended. Therefore, the cushioning performance of the vehicle hood 10 can be improved.

(5) A fourth reinforcing portion 48 formed by bending the plate surface is provided on the first end side 51 of the rear leg second surface portion 41. On the other hand, the second end side 52 facing the first end side 51 is provided with a non-reinforced portion whose plate surface is not bent. With such a configuration, the bending deformation on the second end side 52 side can be promoted while suppressing the bending deformation on the first end side 51, and the rear leg portion 7 can be deformed as intended. You can For example, the rear leg portion 7 can be bent and deformed so that the third bent portion 43 moves above the rear surface portion 5. Therefore, it is possible to increase the deformation stroke of the rear leg portion 7 when an external force is applied, and it is possible to improve the cushioning performance of the vehicle hood 10.

(6) As shown in FIG. 5, the boundary portion (third bent portion 43) forming the boundary between the rear leg first surface portion 40 and the rear leg second surface portion 41 is a boundary 50 (the vehicle outer side of the rear surface portion 5). It is arranged parallel to the edge side). As a result, it is possible to easily bend the entire area near the boundary 50 when an external force is applied. That is, it is possible to increase the deformation stroke of the rear leg portion 7 when an external force is applied, and it is possible to improve the cushioning performance of the vehicle hood 10.

(7) Similarly, the boundary between the rear leg second surface portion 41 and the rear leg third surface portion 42 is arranged parallel to the boundary between the rear leg first surface portion 40 and the rear leg second surface portion 41. With such a configuration, the rear leg second surface portion 41 can be easily deformed in the direction perpendicular to the plate surface (buckling direction). Therefore, it is possible to increase the deformation stroke of the rear leg portion 7 when an external force is applied, and it is possible to improve the cushioning performance of the vehicle hood 10.

(8) By providing the third bead 46 and the fourth bead 47 in the third bent portion 43, it is possible to suppress deformation at the lower end of the rear leg first surface portion 40 (upper end of the rear leg second surface portion 41). It is possible to easily maintain the bending angle θ ₄ . As a result, bending deformation near the boundary 50 can be promoted, and the deformation stroke of the rear leg 7 can be increased. In addition, since the bending angle θ ₄ of the third bent portion 43 is easily maintained, it is possible to prevent the third bent portion 43 from being deformed such that the third bent portion 43 falls below the rear surface portion 5, and the rear leg portion 7 is prevented. It can be transformed as intended. Therefore, the cushioning performance of the vehicle hood 10 can be improved.

(9) By providing the plurality of

beads

46 and 47, it is possible to strongly suppress the deformation of the third bent portion 43 when an external force is applied, and to more reliably deform the rear leg portion 7 as intended. You can Therefore, the cushioning performance of the vehicle hood 10 can be improved. In particular, it is possible to prevent a situation in which the third bent portion 43 bends and falls downward, resulting in a small deformation stroke of the rear leg portion 7.

[4. Modification]
The above embodiment is merely an example, and is not intended to exclude various modifications and application of techniques that are not explicitly shown in this embodiment. Each configuration of the present embodiment can be variously modified and implemented without departing from the spirit thereof. In addition, it can be selected as needed, or can be combined as appropriate.

In the above-described embodiment, the fourth reinforcing portion 48 is formed by bending the plate surface of the rear leg second surface portion 41 twice and raising it. On the other hand, a portion obtained by bending the plate surface of the rear leg second surface portion 41 once may be used as the fourth reinforcing portion 48. The same applies to the fifth reinforcing portion 49, as long as it has a structure that is bent to reinforce the end side of the leg portion.
