Description

The present invention relates to a vehicle body front structure.

As a vehicle body front structure, for example, a structure is known in which bumper beams span left and right front side frames, support pieces are raised from the bumper beams, and the raised support pieces support a grille bracket. A grille bracket is a component of the bumper face. Therefore, by supporting the grille bracket with the support pieces, it is possible to suppress the bumper face from sagging (see, for example, Patent Document 1).

Japanese Patent No. 6304202

By the way, the bumper beam is generally arranged between the bumper face and the front bulkhead in the longitudinal direction of the vehicle body. Therefore, the support piece rising from the bumper beam is also arranged between the bumper face and the front bulkhead. Therefore, it is difficult to secure a mounting space between the bumper face and the front bulkhead for mounting on-vehicle components such as a radar device and a grille shutter.

It is an object of the present invention to provide a vehicle body front structure that can easily secure a mounting space for vehicle-mounted parts such as a radar device and a grille shutter between a bumper face and a front bulkhead, and that can suppress sagging of the bumper face. aim.

In order to solve the above problems, the present invention proposes the following means.
(1) In the vehicle body front structure according to the present invention, a bumper face (for example, the front bumper face 17 in the embodiment) is provided in the front part of the vehicle body, and a front bulkhead (for example, the front bulkhead in the embodiment) is provided behind the bumper face. In a vehicle body front structure provided with a front bulkhead 12) (for example, the vehicle body front structure 10 of the embodiment), a base front part supported on the upper part of the front bulkhead and arranged toward the front of the vehicle body (for example, the base front surface portion 31 of the embodiment) and a base upper surface portion (for example, the base upper surface portion 32 of the embodiment) provided at the upper end of the base front surface portion (for example, the base (for example, the and a bumper stay (for example, the first bumper stay 14 and the second bumper stay 15 of the embodiment) supported by the base and the front bulkhead and fixing the bumper face, wherein the bumper stay is a front fixing portion (for example, the front fixing portions 51 and 71 of the embodiment) that fixes the bumper face; (For example, the rear upper fixing portions 52 and 72 of the embodiment), and the rear lower fixing portion (for example, the rear lower fixing portion of the embodiment) arranged below the rear upper fixing portion and provided on the front surface of the base. 47, 67), and the front fixing part, the rear upper fixing part, and the rear lower fixing part are arranged at the respective vertices of a triangle (for example, the triangles 60, 80 in the embodiment).

According to this configuration, a bumper stay for fixing the bumper face to the base and the front bulkhead is provided. The bumper stay includes a front fixing portion, a rear upper fixing portion, and a rear lower fixing portion. The front fixing portion fixes the bumper face. In addition, the rear upper fixing portion is arranged behind the front fixing portion of the vehicle body and provided on the upper surface of the base. Further, the rear lower fixing part is arranged below the rear upper fixing part and provided on the front surface of the base. In addition, anterior, posterior superior, and posterior inferior fasteners were placed at each vertex of the triangle.
Further, since the bumper face is provided on the front fixing portion, the weight (load) of the bumper face acts downward on the front fixing portion. Therefore, the load acting on the front fixing portion is dispersed (converted) into a tensile load acting on the rear upper fixing portion and a compressive load acting on the rear lower fixing portion.

The rear lower fixing part is provided on the front surface of the base (that is, the base). Also, the base is supported by the front bulkhead. The front bulkhead is a member with high strength and rigidity that forms part of the vehicle body frame. Therefore, the compressive load acting on the rear lower fixed portion can be reliably supported by the base (that is, the front bulkhead).
On the other hand, the rear upper fixing part is provided on the upper surface of the base (that is, the base). Therefore, the tensile load acting on the rear upper fixing portion can be supported by the base (that is, the front bulkhead).
Thereby, the weight of the bumper face can be supported by the bumper stay, and the sagging of the bumper face can be suppressed.

Here, a base is supported on the upper portion of the front bulkhead, and the bumper stay is supported on the base. Therefore, the bumper stay can be arranged above the space between the bumper face and the front bulkhead. This makes it possible to easily secure a mounting space between the bumper face and the front bulkhead for mounting in-vehicle components such as a radar device and a grille shutter.

(2) The bumper stay has a width in the height direction (for example, widths W1 and W2 in the height direction in the embodiment) that gradually increases from the front fixing portion toward the rear of the vehicle body where the front bulkhead is arranged. good.

According to this configuration, the width of the bumper stay in the height direction is gradually increased from the front fixing portion toward the rear of the vehicle body. Therefore, for example, the lower side connecting the front fixing portion and the rear lower fixing portion can be extended downward toward the rear of the vehicle body. As a result, when the load of the bumper face acts on the front fixed part, part of the load acting on the front fixed part is dispersed (converted) into a compressive load acting in the direction in which the rear lower fixed part pushes the front part of the base. ) can be done easily. Therefore, the compressive load can be easily transmitted to the front bulkhead to support it, and the sagging of the bumper face can be further suppressed.

(3) The bumper stay includes an upper surface portion (for example, upper surface portions 44 and 64 in the embodiment) having the front fixing portion and side portions (for example, side surface portions 45 and 65 in the embodiment) extending downward from the upper surface portion. and a ridgeline formed by a portion where the upper surface and the side surface intersect (for example, the ridgelines 46 and 66 of the embodiment), and the ridgeline is a recessed section (for example, the It may have recesses 61, 81).

According to this configuration, the ridgeline portion is formed at the portion where the upper surface portion and the side surface portion of the bumper stay intersect. Further, recesses were formed in the ridges. Therefore, the strength of the bumper stay itself can be improved by the recessed portion, and, for example, deformation of the upper surface portion toward the side surface portion across the ridgeline portion can be suppressed. As a result, the load acting on the front fixing portion from the bumper face can be strongly supported by the bumper stay, and the load acting on the front fixing portion can be supported by the bumper stay.

(4) The rear upper fixing portion is arranged so as to be superimposed on the base upper surface portion, and the upper surface portion of the bumper stay (for example, the upper surface portions 44 and 64 in the embodiment) is formed by the front fixing portion and the rear upper surface portion. In addition to the fixed portion, a stepped portion (for example, the stepped portions 53 and 73 of the embodiment) that slopes downward from the front fixed portion toward the rear upper fixed portion may be provided.

According to this configuration, the bumper stay has the front fixing portion, the rear upper fixing portion, and the stepped portion on the upper surface portion. The rear upper fixing portion is provided so as to overlap the base upper surface portion and the front bulkhead. Further, the stepped portion extends so as to be inclined downward from the front fixing portion toward the rear upper fixing portion. Therefore, the rigidity of the bumper stay can be improved by improving the rigidity of the upper surface portion (particularly, surface rigidity). As a result, the load acting on the front fixing portion from the bumper face can be easily transmitted to the base side through the bumper stay, and the sagging of the bumper face can be further suppressed.

(5) The base is arranged at the rear portion of the bumper stay, and the front surface of the base faces the front protrusion of the front bulkhead (for example, the left front protrusion 24 and the lower right connection portion 35 in the embodiment). The upper stiffener is formed in a U-shape so as to vertically sandwich the forward protruding portion in an extended state, and is attached to a pair of vertical legs of the front bulkhead (for example, the left and right vertical legs 22 in the embodiment). ).

According to this configuration, by forming the base in a U-shape, the forward protruding portion of the front bulkhead can be vertically sandwiched between the bases. Therefore, the rigidity of the base can be increased, and the base can serve as an upper stiffener (that is, a reinforcing member). Furthermore, the base was stretched over a pair of vertical legs of the front bulkhead. Therefore, the base can be firmly supported by the front bulkhead in a state where the base is arranged on the front side of the vehicle body of the front bulkhead. A bumper stay is attached to this base. As a result, the bumper stay can be firmly fixed to the base in a state where the bumper stay is arranged from the base toward the front of the vehicle body.

Here, for example, it is conceivable that the bumper face is arranged with a relatively large distance to the front side of the vehicle body with respect to the front bulkhead. Even in this case, the length of the bumper stay in the longitudinal direction of the vehicle body can be reduced by arranging the base in front of the front bulkhead of the vehicle body. As a result, the bumper face can be strongly supported by the bumper stay.

In addition, the front protruding portion of the front bulkhead was sandwiched between the bases from above and below, and the bases were spanned over the pair of vertical legs of the front bulkhead. Therefore, the front bulkhead can be reinforced with the base.
Here, while the vehicle is running, for example, it is conceivable that a torsional load is input to the front bulkhead by running only one wheel over a step. In this case, the rigidity of the front bulkhead against a torsional load can be increased by the base (that is, the upper stiffener).

(6) In addition to the pair of vertical leg portions, the front bulkhead includes a horizontal member (for example, the upper horizontal member 23 of the embodiment) that extends over the pair of vertical leg portions and has the forward projecting portion. The base has a lower connecting portion (for example, a lower left connecting portion 34 and a lower right connecting portion 35 in the embodiment) fixed to the pair of vertical legs below the horizontal member. good too.

According to this configuration, the forward protruding portion of the lateral member is arranged so as to be sandwiched between the bases. Further, the lower connecting portion of the base is fixed to the pair of vertical legs below the horizontal member. As a result, the base can increase the rigidity of the front bulkhead, for example, against a load that bends the pair of vertical legs outward in the vehicle width direction into a dogleg shape (V shape).

(7) A duct (for example, the duct 91 of the embodiment) is provided in front of the front bulkhead and guides outside air to the front bulkhead side, and the duct is connected to the base and the bumper stay. It may be fixed.

According to this configuration, a duct is provided in front of the vehicle body of the front bulkhead, and the duct is fixed to both the base and the bumper stay. Therefore, the duct can be firmly supported by both the base and the bumper stay. As a result, even if the duct is made of resin, for example, it is less likely to be affected by vibrations while the vehicle is running, and the duct is less likely to affect the air path.

(8) A center upper beam (for example, the center upper beam 16 of the embodiment) that supports the upper flange of the bumper face (for example, the upper flange 17a of the embodiment) is provided, and the center upper beam is the front end of the bumper stay. It may be fixed to the fixed part.

According to this configuration, the upper flange of the bumper face is supported by the center upper beam, and the center upper beam is fixed to the fixing portion of the bumper stay. Thereby, the upper flange can be extended horizontally in the vehicle width direction, and the shape of the upper flange can be simplified.

(9) The base may have a recessed portion (for example, the recessed portion 36 in the embodiment) that is recessed downward at the center in the vehicle width direction.

Here, for example, a hood lock mechanism is provided at the central portion of the lateral member in the vehicle width direction. Therefore, a recess is formed in the center of the base in the vehicle width direction. Therefore, the recess 36 is arranged in front of the vehicle body of the hood lock mechanism.
As a result, it is possible to secure a space between the concave portion of the base and the hood in which an unlocking lever (not shown) for unlocking the hood locking mechanism can be operated. The hood can be opened by unlocking the hood lock mechanism with the unlock lever.

(10) The front fixing portion of the bumper stay may be arranged at a position higher than the rear upper fixing portion in the vertical direction.

According to this configuration, the front fixing portion of the bumper stay is arranged at a higher position in the vertical direction than the rear upper fixing portion. Therefore, for example, when a plurality of bumper stays are provided on the base at intervals in the vehicle width direction, the front fixing part of the bumper stay provided at a position where the upper surface of the base is low is replaced with the front fixing part of the other bumper stay. They can be placed at the same height.
As a result, the front fixing portions of the plurality of bumper stays provided on the base can be arranged horizontally in the vehicle width direction, and the bumper face can be fixed with high accuracy.

ADVANTAGE OF THE INVENTION According to this invention, the mounting space of vehicle-mounted components, such as a radar apparatus and a grille shutter, can be easily ensured between a bumper face and a front bulkhead, and sagging of a bumper face can be suppressed.

In this case, too, the length of the first bumper stay 14 and the second bumper stay 15 in the longitudinal direction of the vehicle body can be reduced by arranging the base 13 in front of the front bulkhead 12 of the vehicle body. Thereby, the front bumper face 17 can be firmly supported by the first bumper stay 14 and the second bumper stay 15 .

The left front projecting portion 24 and the right front projecting portion 25 of the upper horizontal member 23 are sandwiched between the bases 13 from above and below, and the bases 13 are stretched over the left and right vertical legs 22 of the front bulkhead 12 . . Therefore, the front bulkhead 12 can be reinforced with the base 13 .
Here, while the vehicle Ve is running, for example, it is conceivable that a torsional load is input to the front bulkhead 12 by running only one wheel on a step. In this case, the rigidity of the front bulkhead 12 against torsional loads can be increased by the base 13 (that is, the upper stiffener).

Further, as shown in FIG. 3 , the left front projecting portion 24 and the right front projecting portion 25 of the upper lateral member 23 are arranged so as to be sandwiched between the bases 13 . Further, the lower left connecting portion 34 and the lower right connecting portion 35 of the base 13 are fixed to the upper ends 22a, 22a of the left and right vertical legs 22, 22 below the lower end of the upper horizontal member 23. As shown in FIG. As a result, the base 13 can increase the rigidity of the front bulkhead 12, for example, against a load that bends the left and right vertical legs 22 outward in the vehicle width direction into a dogleg shape (V shape). .
That is, for example, when a load for bending the left and right vertical legs 22 outward in the vehicle width direction is input to the front bulkhead 12, the left and right vertical legs 22 are bent outward in the vehicle width direction. The base 13 can suppress bending in a V-shape (V-shape).
