The second bead 40 </ b> C is divided up and down on the rear end portion side of the bracket base portion 42 and is discontinuous. For this reason, the bumper bracket 40 is set so that the rigidity on the rear end side is lower than the substantially central side in the side view.

  A first flange portion 48 that is bent to the right side of the vehicle is formed at a portion from the front end of the second arm portion 46 to the rear end of the upper end of the first arm portion 44 in the outer peripheral portion of the bumper bracket 40. Further, a bumper cover mounting portion 54 is formed at the front end of the first arm portion 44 which is one end side of the bumper bracket 40 and is bent to the vehicle right side (one side in the vehicle width direction) at the upper portion thereof. The bumper cover mounting portion 54 is continuous with the front end of the first flange portion 48, and the general surface is disposed with the surface including the vehicle front-rear direction and the vehicle width direction (in other words, a horizontal plane) as the surface direction. It protrudes to the right side of the vehicle from the part 48. A mounting hole 54 </ b> B is formed through the central portion of the bumper cover mounting portion 54. The bumper cover mounting portion 54 is superposed on the lower surface side of the mounting end portion 22 </ b> A as an end portion on the vehicle longitudinal direction inner side extending from the upper end flat portion 22 of the front bumper cover 20 to the vehicle rear side. A mounting hole 22B is formed through the center of the mounting end 22A of the front bumper cover 20, and the lower part of the clip 62 constituting the mounting means passes through the mounting hole 22B and the mounting hole 54B, so that the bumper cover is mounted. The part 54 is attached to the attachment end 22A.

  Further, as shown in FIG. 4, the bumper bracket 40 has a front end surface 54A of a bumper cover mounting portion 54 as an end surface on one end side facing the vehicle right side (one side in the vehicle width direction) in the vehicle plan view. It is inclined (outside in the vehicle longitudinal direction). The front end portion on the right side of the front end surface 54A is a load input portion 56 to which a collision load F is input from the front bumper cover 20 side via the front bumper absorber 18A and the front bumper reinforcement 18B. The load input portion 56 is offset to the vehicle right side (one side in the vehicle width direction) in the vehicle plan view with respect to the position at which the bumper bracket 40 is attached to the center brace 38 (attachment position of a vehicle body attachment portion 58 described later in detail). (The position in the vehicle width direction is shifted). The inclination angle of the front end surface 54A of the bumper cover mounting portion 54 is set in consideration of the workability of assembling the front bumper cover 20.

  On the other hand, as shown in FIG. 3, the rear end portion of the bracket base portion 42 which is the other end side of the bumper bracket 40 is overlapped with the vehicle right side (the rear side in the drawing) side wall portion 38 </ b> B of the center brace 38. A vehicle body mounting portion 58 to be matched is provided. Bolt insertion holes 56A are formed in the upper and lower portions of the vehicle body attachment portion 58 so as to correspond to the bolt insertion holes (not shown) of the center brace 38 and the weld nuts 64B (see FIG. 4). A bolt 64A (male screw member) constituting a part of fastening means (attachment means) from the side opposite to the center brace 38 of the vehicle body attachment portion 58 in the bumper bracket 40 is connected to the bolt insertion hole 56A and the center brace of the bumper bracket 40. 38 is inserted into a bolt insertion hole (not shown) and screwed into a weld nut 64B (see FIG. 4). Thus, the vehicle body attachment portion 58 of the bumper bracket 40 is fastened and attached to the side wall portion 38B of the center brace 38 in a surface contact state.

  As shown in FIG. 4, the bumper bracket 40 is formed such that a portion between the bumper cover mounting portion 54 and the vehicle body mounting portion 58 is substantially linear in a vehicle plan view. More specifically, the bumper bracket 40 is a point A in a range where the bumper cover mounting portion 54 is pressed by the head 62A of the clip 62 in the vehicle plan view (the point in the drawing that is the leftmost side of the vehicle). ) And one point B in the range restrained by the head of the bolt 64 </ b> A at the vehicle body mounting portion 58 without being deviated (in a region including the virtual straight line L). In the present embodiment, the bumper bracket 40 is disposed substantially along the vehicle front-rear direction.

  As shown in FIG. 3, the outer periphery of the bumper bracket 40 has a second portion bent to the vehicle right side (one side in the vehicle width direction) at a portion from the rear end of the second arm portion 46 to the upper end of the bracket base portion 42. A flange portion 50 is formed, and a third flange portion 52 bent to the right side of the vehicle is formed at the lower end of the bracket base portion 42.

  The second flange portion 50 and the third flange portion 52 are on the rear end side (the other end side) of the bumper bracket 40 and on the vehicle front side (the vehicle front-rear direction outer side) with respect to the vehicle body mounting portion 58 (in other words, Notch portions 50A and 50B as weak portions are formed in the vicinity of the vehicle front side of the vehicle body attachment portion 58. That is, the notches 50A and 50B are formed so as to open to the vehicle right side at the vehicle right side (one side in the vehicle width direction) on the rear end side (the other end side) of the bumper bracket 40. The notches 50A and 50B are deformed when a collision load F equal to or greater than a predetermined value is input to the load input unit 56, and the bending deformation starts to bend the bumper bracket 40 toward the vehicle right side (one side in the vehicle width direction). It is set so that it becomes (for the cause of side fold).

  The second arm portion 46 of the bumper bracket 40 is formed with a grill attachment portion 60 that is bent at the upper end thereof to the vehicle right side (one side in the vehicle width direction). The grill attachment portion 60 has a front end continuous with the upper end of the first flange portion 48 and a rear end continuous with the upper end of the second flange portion 50, and a general surface including the vehicle longitudinal direction and the vehicle width direction. (In other words, a horizontal plane) is arranged as a plane direction and protrudes to the right side of the vehicle. A mounting hole 60 </ b> A is formed through the center of the grill mounting portion 60. The grill attachment portion 60 is superposed on the lower surface side of an attachment end portion 26B as an end portion on the inner side in the vehicle front-rear direction extending from the upper end portion of the radiator grille 26 to the vehicle rear side. A mounting hole 26C is formed through the central portion of the mounting end portion 26B of the radiator grille 26, and the lower portion of the clip 66 constituting the mounting means passes through the mounting hole 26C and the mounting hole 60A. Is attached to the attachment end 26B.

  In addition, as shown in FIG. 4, in order to ensure the vehicle vertical direction rigidity of the bumper bracket 40, the bumper cover mounting portion 54, the grill mounting portion 60, and the vehicle body mounting portion 58 are set on the same straight line. Yes. That is, one point C in the range that is pressed by the head 66A of the clip 66 at the grill mounting portion 60 (the point that is the leftmost side of the vehicle in the drawing) is set on the virtual straight line L.

(Operation and effect of the embodiment)
Next, the operation and effect of the above embodiment will be described.

  In the bumper cover support structure according to the present embodiment, as shown in FIG. 3, the bumper bracket 40 has a front bumper cover mounting portion 54 attached to the mounting end portion 22 </ b> A of the front bumper cover 20 and a rear end side. The vehicle body attachment portion 58 is attached to the center brace 38, and a portion between the bumper cover attachment portion 54 and the vehicle body attachment portion 58 is formed in a substantially linear shape in a plan view of the vehicle. For this reason, the support rigidity of the front bumper cover 20 by the bumper bracket 40 in the normal state (the rigidity of the bumper bracket 40 in the vertical direction of the vehicle) is easily ensured, and positioning when the front bumper cover 20 is assembled is easy.

  In addition, as shown in FIG. 4, the bumper cover mounting portion 54, the grill mounting portion 60, and the vehicle body mounting portion 58 are set on the same straight line (on the virtual straight line L) in the vehicle plan view. For this reason, even if the radiator grille 26 (see FIG. 3) is attached to the bumper bracket 40, the support rigidity (rigidity in the vehicle vertical direction) by the bumper bracket 40 is easily ensured.

  On the other hand, when the barrier 70 (impact) collides with the front bumper cover 20, the front bumper absorber 18 </ b> A and the front bumper reinforcement are applied to the load input portion 56 provided on the front end side of the bumper bracket 40 from the front bumper cover 20 side. The collision load F is input via the ment 18B. In other words, the collision point between the barrier 70 and the bumper bracket 40 via the front bumper 18 is a contact point between the load input unit 56 and the front bumper 18 (front bumper reinforcement 18B).

  Here, the front end surface 54A of the bumper bracket 40 is inclined toward the vehicle front side toward the vehicle right side in a plan view of the vehicle, and the end portion on the vehicle right side of the front end surface 54A of the bumper bracket 40 serves as the load input portion 56. . As a result, the load input portion 56 (input point of the bumper bracket 40) is in the plane of the vehicle with respect to the mounting position of the vehicle body mounting portion 58 serving as a fulcrum of the bumper bracket 40 (fastening point between the bumper bracket 40 and the center brace 38). It is set to be offset to the right side of the vehicle. For this reason, when a collision load F is input to the load input portion 56 of the bumper bracket 40 from the front bumper 18 side during a light collision, a moment M in a direction of bending toward the right side of the vehicle acts on the bumper bracket 40. . Further, as shown in FIG. 5, when the bumper bracket 40 is bent and deformed to some extent (rotational motion) during a light collision, the front end surface 54A of the bumper bracket 40 receives the collision load F from the front bumper 18 over the entire end surface. Therefore, the bumper bracket 40 is efficiently bent and deformed (broken) toward the right side of the vehicle.

  For example, the bumper bracket is bent in a crank shape in a plan view of the vehicle, and the bumper cover mounting portion is offset to one side in the vehicle width direction with respect to the mounting position of the vehicle body mounting portion. In the contrast structure as set, the bumper cover mounting portion serves as a load input portion during a light collision, and a moment in a direction to bend the bumper bracket toward one side of the vehicle acts. However, in the bumper bracket having such a contrast structure, the bumper bracket mounting portion is offset to one side in the vehicle width direction with respect to the mounting position of the vehicle body mounting portion because the bumper bracket is bent in a crank shape in a plan view of the vehicle. Therefore, compared to the case of this embodiment, it is difficult to secure the support rigidity of the front bumper cover by the bumper bracket (the rigidity of the bumper bracket in the vehicle vertical direction). Inconveniences such as difficulty in positioning in the case occur. On the other hand, the bumper bracket 40 of the present embodiment is set such that the load input portion 56 is offset to the vehicle right side (one side in the vehicle width direction) with respect to the mounting position of the vehicle body mounting portion 58 in the vehicle plan view. However, since the portion between the bumper cover mounting portion 54 and the vehicle body mounting portion 58 is formed in a substantially linear shape in a vehicle plan view, the support rigidity of the front bumper cover 20 by the bumper bracket 40 (the vehicle vertical direction of the bumper bracket 40). This is advantageous in ensuring the rigidity of the machine.

  In the bumper cover support structure according to the present embodiment, a notch is provided on the rear end side of the bumper bracket 40 and on the vehicle front side with respect to the vehicle body attachment portion 58 (in other words, in the vicinity of the vehicle front side of the vehicle body attachment portion 58). 50A and 50B are formed, and the notches 50A and 50B are bent when the impact load F of a predetermined value or more is input to the load input unit 56 to bend the bumper bracket 40 toward the right side of the vehicle. The starting point of deformation. Thus, the notches 50A and 50B are formed near the vehicle front side of the vehicle body mounting portion 58 on the rear end side of the bumper bracket 40, and the distance (moment arm length) from the load input portion 56 (input portion) is maximized. Therefore, a larger bending moment can be applied to the bumper bracket 40.

  Further, since the notches 50A and 50B are formed at the right side of the vehicle on the rear end side of the bumper bracket 40, they are easily deformed toward the right side of the vehicle from the notches 50A and 50B at the time of a light collision. As a result, at the time of a light collision, the bumper bracket 40 is bent toward the right side of the vehicle so that the bumper bracket 40 is bent around the vehicle vertical direction with the notches 50A and 50B as starting points of bending deformation, and the energy at the time of the collision Therefore, the retreat of the bumper bracket 40 is suppressed, and the interference between the bumper bracket 40 and the capacitor 24B is prevented or suppressed.

  As described above, according to the bumper cover support structure according to the present embodiment, it is possible to prevent or suppress interference between the bumper bracket 40 and the capacitor 24B (other member) due to the retreat of the bumper bracket 40 at the time of a light collision. it can. As a result, repair costs during light collisions are reduced.

  In addition, the bumper cover support structure according to the present embodiment realizes a configuration in which a rectangular extension portion is not extended from the front bumper cover 20 between the radiator grille 26 and the lamp lens 28 (ensures the degree of freedom of design). However, it can be said that the structure ensures both the mounting rigidity of the front bumper cover 20 and the reduction of the repair cost during a light collision.

(Supplementary explanation of the embodiment)
In the above embodiment, the bumper cover support structure for supporting the front bumper cover 20 has been described as shown in FIG. 3 and the like. However, the bumper cover support structure is the rear end side of the vehicle (the most in the vehicle front-rear direction). You may apply to the bumper cover support structure for supporting the rear bumper cover extended along a vehicle width direction on the outer side.

  Further, in the above embodiment, the fragile portions are the notches 50A and 50B, but the fragile portion is formed so that the rear end portion of the bead corresponding to the second bead 40C extends to the vicinity of the vehicle front side of the vehicle body attachment portion 58, for example. As a result, the low-rigidity portion set to be less rigid than the front region where the bead is formed and the flange portions corresponding to the second flange portion 50 and the third flange portion 52 are mounted on the vehicle body in a plan view of the vehicle. By forming the portion 58 in the vicinity of the front side of the vehicle, a low-rigidity portion set to be less rigid than the front region where the flange portion is formed, or a rear end portion of the bumper bracket (40) in the vehicle vertical direction. Other brittle parts such as a through-hole or the like penetrating through a general surface of the rear end portion of the bumper bracket (40) in the thickness direction may be used.

  Moreover, in the said embodiment, although the bumper bracket 40 is arrange | positioned along the vehicle front-back direction in the vehicle planar view, a bracket is arrange | positioned along the diagonal direction with respect to the vehicle front-back direction in the vehicle plan view, for example. It may be a bracket.

  Furthermore, in the said embodiment, although the case where "the one side of the vehicle width direction" of Claims 1 to 3 was the right side of the vehicle was described as an example, "Vehicle of Claims 1 to 3" The “one side in the width direction” may be the left side of the vehicle.

  Furthermore, in the above-described embodiment, the bumper bracket 40 has the front end surface 54A of the bumper cover mounting portion 54 inclined toward the vehicle front side in the vehicle plan view, but one end side of the bracket is, for example, The end portion on one side in the vehicle width direction in a vehicle plan view may be shaped to protrude outward in the vehicle front-rear direction. In this case, the tip of the protruding portion becomes the load input portion.

  Note that the concept of “the portion between the bumper cover mounting portion and the vehicle body mounting portion is formed in a substantially linear shape in a plan view of the vehicle” according to claim 1 is shown in FIG. 4 of the above embodiment. Thus, in a vehicle plan view, the bumper cover mounting portion 54 has a point A that is pressed by the head 62A of the clip 62 (in the drawing, the point on the leftmost side of the vehicle) and the vehicle body mounting portion 58. In addition to the case where the bumper bracket 40 is formed in a straight line shape (in a region including the virtual straight line L) without detaching from the virtual straight line L connecting the one point B in the range restrained by the head of the bolt 64A, the vehicle In the plan view, the bumper bracket (40) is slightly deviated from the imaginary straight line L and formed in a straight line, and substantially in a straight line without being deviated from the imaginary straight line L. Similar actions and effects Also include those found to have been formed in a linear shape (substantially similar vehicle vertical direction stiffness) is obtained in a region including a substantially imaginary straight line L.

  In addition to the above, the concept of “the portion between the bumper cover mounting portion and the vehicle body mounting portion is formed in a substantially linear shape in a vehicle plan view” according to claim 1 The bumper bracket (40) does not come off from the virtual straight line L and is slightly bent (for example, in the shape of a large-diameter arc) in a vehicle plan view, and does not come off from the virtual straight line L. Substantially the same action and effect (substantially the same vertical rigidity in the vehicle) can be obtained and formed substantially linearly without deviating from the virtual straight line L. The bumper bracket (40) is slightly deviated from the virtual straight line L in the vehicle plan view and is slightly bent in the vehicle plan view. Without going off the virtual straight line L Substantially the same operation and effect (substantially similar vehicle vertical rigidity) as in the case of being formed in a shape, and substantially linearly formed in a region including the virtual straight line L This includes those that are allowed.
