Description

  The present invention relates to a vehicle front hood.

  In vehicles such as automobiles, an engine room is provided at the front of the vehicle body, and a vehicle front hood that is opened and closed is disposed above the engine room. There are cases where a collided object rides on the front hood for a vehicle when the vehicle collides with a collided object (for example, a pedestrian). For this reason, the front hood for a vehicle is designed so as to absorb the collision energy by being deformed and to reduce the impact load on the collision target (particularly a pedestrian).

  Patent Document 1 describes a bonnet structure including a bonnet formed of an outer panel and an inner panel, and a bonnet stiffener that is interposed between the outer panel and the inner panel and supports the outer panel.

  The bonnet stiffener of Patent Document 1 has a stiffener body, two front legs, and three rear legs, which are integrally formed. The stiffener body is a rectangle that is long in the vehicle width direction, and is disposed at a position facing the lower surface of the outer panel. The front leg portion extends forward from the front end of the stiffener body and is fixed to the upper surface of the inner panel. The rear leg portion extends rearward from the rear end of the stiffener main body and is fixed to the upper surface of the inner panel.

  For this reason, the bonnet stiffener of Patent Document 1 is supported by the front leg portion and the rear leg portion that reach the inner panel from the stiffener main body portion and is fixed to the upper surface of the inner panel. Can be supported from.

JP 2006-60395 A

  However, in the bonnet structure described in Patent Document 1, no particular measures are taken to reduce the base material discarded when the bonnet stiffener is cut out from the base material. Therefore, there has been room for improvement in terms of reducing the amount of material used to form the bonnet stiffener.

  In view of such a problem, an object of the present invention is to provide a vehicle front hood capable of reducing the amount of material used for a reinforcing member and reducing the weight and cost.

  In order to solve the above-described problems, a typical configuration of a vehicle front hood according to the present invention is a vehicle front hood that is disposed at a front portion of a vehicle body, and is combined with each other and faces a vehicle outer side and a vehicle inner side, respectively. A hood outer panel and a hood inner panel, and a reinforcing member disposed between the hood outer panel and the hood inner panel, the reinforcing member having a flat plate shape and having an opening; and a main body portion disposed along the hood outer panel; A rear side fixing portion that extends in a cantilever shape from the rear edge of the opening into the opening and is bent toward the hood inner panel at the rear edge to be fixed by reaching the hood inner panel; and Front side fixing that extends forward from the front edge and is bent toward the hood inner panel at the front edge to reach the hood inner panel and be fixed Characterized in that it has and.

  ADVANTAGE OF THE INVENTION According to this invention, the usage-amount of the material of a reinforcement member can be reduced and the vehicle front hood which can reduce a weight and cost can be provided.

It is a figure showing roughly the appearance of the front hood for vehicles concerning the example of the present invention. It is a figure which expands and shows a part of vehicle front hood of FIG. It is a figure which shows the AA cross section of the vehicle front hood of FIG. It is a figure which shows the state which looked at the reinforcement member of FIG. 3 from diagonally upward. It is a figure which shows the behavior at the time of the collision of the reinforcement member of FIG. It is a figure which shows typically the reinforcing member of FIG. 2, and the reinforcing member of a comparative example.

  A typical configuration of a vehicle front hood according to an embodiment of the present invention is a vehicle front hood disposed in a front portion of a vehicle body, and is combined with each other and has a hood outer panel facing the vehicle outer side and the vehicle inner side, respectively. A hood inner panel, and a reinforcing member disposed between the hood outer panel and the hood inner panel, the reinforcing member having a flat plate shape and having an opening, and being disposed along the hood outer panel; From the rear edge, which extends in a cantilevered manner into the opening from the rear edge and is bent toward the hood inner panel at the rear edge to reach and fix the hood inner panel, and from the front edge of the main body It has a front side fixing part that extends forward and is bent toward the hood inner panel at the front edge to be fixed by reaching the hood inner panel. The features.

  According to the said structure, a front side fixing | fixed part can be fixed to a hood inner panel by being bent by the front edge of a main-body part. Further, the rear fixing portion can be fixed to the hood inner panel by being bent at the rear edge of the opening. For this reason, the reinforcing member can be fixed to the hood outer panel via the main body portion, and can be fixed to the hood inner panel via the front side fixing portion and the rear side fixing portion. Further, since the rear fixing portion before being bent extends in a cantilever shape within the opening of the main body portion, it exists within the range of the main body portion. Therefore, when the main body part, the front side fixing part, and the rear side fixing part are cut out from the base material, the base material may be of a size that can cover the main body part and the front side fixing part, and a region for the rear side fixing part is prepared separately. There is no need. Therefore, according to the above configuration, since the size of the base material can be reduced, the amount of material used can be reduced, and the weight and cost can be reduced.

  The fixed point of the rear fixed portion with the hood inner panel is preferably located on the front side of the vehicle, rather than the intersection with the vertical hood inner panel extending from the rear edge of the opening in a direction perpendicular to the hood outer panel. . As a result, the fixing point of the rear fixing portion with the hood inner panel in the direction perpendicular to the hood outer panel, that is, the load input direction, is more than the position of the rear edge of the opening of the main body portion, that is, the upper end of the rear fixing portion. It is arranged on the front side of the vehicle. For this reason, when a pedestrian collides with the vehicle front hood and the reinforcing member receives a load, the reinforcing member is deformed so that the rear side fixing portion is crushed in the vehicle vertical direction due to the load in the vehicle vertical direction. Deformation is more reliably caused by the generation of a moment toward the rear side. Therefore, the reinforcing member is deformed by receiving a load at the time of collision and the rear fixing portion is bent toward the rear side of the vehicle, so that it becomes easy to absorb the impact and the injury value to the colliding pedestrian can be reduced. Further, since the rear fixing portion can be formed along the vehicle vertical direction, the rear fixing portion is likely to be bent when subjected to a collision load in the vehicle vertical direction.

  The rear side fixing portion has a weak portion, and when the main body portion is viewed from the vehicle width direction, forms a first inclination angle that is an acute angle with respect to a reference direction toward the vehicle front side along the main body portion, The front side fixing portion may form a second inclination angle that is an acute angle with respect to the reference direction, and the first inclination angle may be larger than the second inclination angle. Thus, in the reinforcing member, the inclination angle of the main body portion with respect to the reference direction is larger in the rear side fixing portion than in the front side fixing portion. For this reason, the load at the time of a collision is reliably transmitted to a reinforcement member at a rear side fixed part. And since the rear side fixing | fixed part has the weak part which accelerates | stimulates a deformation | transformation, a deformation | transformation of a weak part is reliably performed at the time of a collision. Thereby, since a reinforcement member deform | transforms into a vehicle lower side so that a hood inner panel may be approached at the time of a collision, it can absorb impact energy and can ensure pedestrian protection performance.

  Said hood inner panel has a groove | channel extended in a vehicle width direction, and the fixing point with the hood inner panel of a rear side fixing | fixed part is good to adjoin the vertical wall of the vehicle rear side of a groove | channel. As described above, the rear fixing portion of the reinforcing member is fixed adjacent to the portion of the hood inner panel where the rigidity is high, that is, the vertical wall forming the groove. For this reason, the attachment rigidity with respect to the hood inner panel of a reinforcement member can be improved. Therefore, according to the above configuration, when a relatively low load is input, it is possible to reduce deformation of the reinforcing member together with the hood inner panel and to suppress deformation of the hood outer panel. When a relatively high load is input The impact energy can be absorbed by reliably deforming the reinforcing member.

  The fixing point of the rear fixing portion with the hood inner panel may be a welding point arranged side by side in the vehicle width direction. Here, the vehicle front hood tends to be deformed in the vehicle front-rear direction under a load associated with repeated opening and closing. In the above configuration, the welding points, which are the fixing points of the rear fixing portion with the hood inner panel, are arranged side by side in the vehicle width direction, thereby being orthogonal to the vehicle longitudinal direction, which is the deformation direction of the vehicle front hood. . By arranging the welding points in this way, the load accompanying opening and closing of the front hood for the vehicle can be distributed almost evenly, it becomes difficult for the peeling of the welding to occur, and the fixing strength can be secured.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the examples are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

  FIG. 1 is a diagram schematically showing the appearance of a vehicle front hood 100 according to an embodiment of the present invention. FIG. 2 is an enlarged view showing a part of the vehicle front hood 100 of FIG. FIG. 2A is a perspective view of the vehicle front hood 100 as viewed obliquely from above. FIG. 2B is a view of the vehicle front hood 100 as viewed from above.

  The vehicle front hood 100 is disposed above an unillustrated engine room at the front of the vehicle body. The vehicle front hood 100 includes a hood outer panel 102 constituting the outer surface thereof, and a hood inner panel 104 and a reinforcing member 106 shown in FIG. In FIG. 2, the hood outer panel 102 is omitted.

  The hood inner panel 104 is a member that constitutes the inner surface of the vehicle front hood 100 and is disposed below the hood outer panel 102. The hood inner panel 104 has a groove 108 extending in the vehicle width direction. The groove 108 has a bottom portion 110 and a vertical wall 112 on the vehicle rear side of the bottom portion 110, and there is a height difference between the vertical wall 112 and the vehicle front and rear. For this reason, the groove | channel 108 becomes a location where the rigidity is high among the hood inner panels 104.

  The reinforcing member 106 is a member disposed between the hood outer panel 102 and the hood inner panel 104, and is formed by cutting out from a base material having a predetermined size (see FIG. 6A). The reinforcing member 106 exhibits surface rigidity with respect to the load when the front hood 100 for the vehicle is opened and closed to maintain the shape of the hood outer panel 102, and deforms at the time of collision to absorb the impact and ensure the pedestrian protection performance. To play a role.

  The reinforcing member 106 includes a main body portion 114, two rear side fixing portions 116 and 118, and a front side fixing portion 120. The main body 114 has a flat plate shape, has two openings 122 and 124, and is disposed along the hood outer panel 102. The two openings 122 and 124 are partitioned by a bridging portion 126 extending in the vehicle front-rear direction, and are arranged side by side in the vehicle width direction. For example, a sealer is applied to the upper surface of the main body 114 at a plurality of predetermined locations, and is adhered to the lower surface of the hood outer panel 102.

  As shown by phantom lines in FIG. 2A, the rear fixing portions 116 and 118 extend in cantilever form from the rear edges 128 and 130 of the openings 122 and 124 into the openings 122 and 124, respectively, before being folded. And within the range of the main body 114. Further, as shown by arrows in FIG. 2A, the rear fixing portions 116 and 118 reach the hood inner panel 104 by being bent toward the hood inner panel 104 at the rear edges 128 and 130. The rear fixing portions 116 and 118 are fixed to the hood inner panel 104 at fixing points 132a, 132b, 134a, and 134b shown in FIG.

  Further, fixing points 132 a, 132 b, 134 a, 134 b of the rear side fixing portions 116, 118 with the hood inner panel 104 are adjacent to the vertical wall 112 of the groove 108 of the hood inner panel 104. That is, in the reinforcing member 106, the rear side fixing portions 116 and 118 are fixed adjacent to the portion of the hood inner panel 104 where the rigidity is high. For this reason, the attachment rigidity with respect to the hood inner panel 104 of the reinforcement member 106 can be improved.

  Therefore, in the vehicle front hood 100, the deformation of the reinforcing member 106 together with the hood inner panel 104 can be reduced when a relatively low load is input, such as when opening and closing, and the deformation of the hood outer panel 102 can be suppressed. Further, the vehicle front hood 100 can absorb the impact energy by reliably deforming the reinforcing member 106 when a relatively high load is input, such as at the time of a collision with a pedestrian.

  Here, the vehicle front hood 100 tends to be deformed in the vehicle front-rear direction under a load accompanying repeated opening and closing. On the other hand, the fixed points 132a, 132b, 134a, 134b are arranged in a straight line in the vehicle width direction as shown in FIG. 2B, and are orthogonal to the deformation direction of the vehicle front hood 100. By arranging the fixing points 132a, 132b, 134a, and 134b in this way, the vehicle front hood 100 can disperse the load accompanying opening and closing substantially evenly, and it is difficult for peeling of welding to occur, and the fixing strength is increased. It can be secured.

  The front side fixing part 120 extends forward from the front edge 136 of the main body part 114 and is bent toward the hood inner panel 104 at the front edge 136 to reach the hood inner panel 104 and be fixed. In this way, the reinforcing member 106 is fixed to the hood outer panel 102 via the main body 114, and is fixed to the hood inner panel 104 via the front fixing part 120 and the rear fixing parts 116, 118.

  FIG. 3 is a view showing an AA cross section of the vehicle front hood 100 of FIG. In the drawing, the hood outer panel 102 is indicated by a chain line. A perpendicular line B extends from the rear edge 128 of the opening 122 in a direction perpendicular to the hood outer panel 102, that is, a load input direction, and intersects the hood inner panel 104 at an intersection C. Hereinafter, the rear fixing portion 116 of the rear fixing portions 116 and 118 will be described. However, the configuration and functions of the rear fixing portion 118 are the same as those of the rear fixing portion 116.

  The fixing point 132a of the rear side fixing part 116 with the hood inner panel 104 is located on the vehicle front side with respect to the intersection C as shown in the figure. That is, the fixing point 132a of the rear side fixing portion 116 is located on the vehicle front side with respect to the input direction of the load with respect to the upper end 137 of the rear side fixing portion 116. For this reason, in the vehicle front hood 100, when the reinforcing member 106 receives a load such as at the time of a collision with a pedestrian, a moment toward the rear side of the vehicle is likely to be generated in the reinforcing member 106.

  The rear-side fixing portion 116 forms a first inclination angle θa that is an acute angle with respect to the reference direction D toward the vehicle front side along the main body portion 114 when the main body portion 114 is viewed from the vehicle width direction as illustrated. Yes. The front fixing portion 120 forms a second inclination angle θb that is an acute angle with respect to the reference direction D. The first inclination angle θa is larger than the second inclination angle θb. As described above, in the reinforcing member 106, the rear fixing portion 116 has a larger inclination angle with respect to the reference direction D of the main body portion 114 than the front fixing portion 120, so that the load at the time of collision is reliably applied to the rear fixing portion 116. Communicated.

  Further, the rear fixing portion 116 is fixed to the hood inner panel 104 on the vehicle rear side of the groove 108 as illustrated. The front side fixing portion 120 is fixed to the hood inner panel 104 on the vehicle front side of the groove 108. Therefore, the reinforcing member 106 is fixed to the hood inner panel 104 via the front fixing part 120 and the rear fixing parts 116 and 118 across the vehicle front and rear portions of the hood inner panel 104 where the rigidity is high. ing. Therefore, the attachment rigidity of the reinforcing member 106 to the hood inner panel 104 can be increased.

  The vehicle front hood 100 further includes a striker 138 attached to the lower surface of the hood inner panel 104 and a striker reinforcing member 140, as shown. The striker reinforcing member 140 is a member that reinforces the attachment location of the striker 138 on the lower surface of the hood inner panel 104, and ensures the strength when the vehicle front hood 100 is opened and closed.

  The striker reinforcing member 140 is fastened to the front fixing portion 120 with the hood inner panel 104 interposed therebetween. For this reason, the load received by the front side fixing portion 120 is also transmitted and distributed to the striker reinforcing member 140 via the hood inner panel 104. Therefore, the attachment rigidity of the reinforcing member 106 to the hood inner panel 104 can be further increased. Further, since joints can be reduced by co-stopping, cost reduction can be realized.

  FIG. 4 is a view showing a state in which the reinforcing member 106 of FIG. 3 is viewed obliquely from above. As shown in FIG. 4A, the rear fixing portion 116 of the reinforcing member 106 reaches the hood inner panel 104 from the rear edge 128 of the opening 122 and is fixed. The rear side fixing part 116 has a weak part 142 as shown in an enlarged view in FIG.

  The fragile portion 142 is a bent portion having a convex shape on the front side of the vehicle, and is formed over the vehicle width direction as shown in FIG. Further, the rear side fixing portion 116 has a bent portion 144. The bent portion 144 is located on the vehicle upper side with respect to the fragile portion 142, and is provided near the rear edge 128 of the opening 122, that is, at the upper end 137. A bead portion 146 extending in the vehicle vertical direction is formed at the center of the bent portion 144 in the vehicle width direction.

  As described above, in the rear fixing portion 116, the bending portion 144 including the bead portion 146 formed on the vehicle upper side than the fragile portion 142 ensures the rigidity of the upper end 137, and the fragile portion 142 promotes deformation at the time of collision. Like to do.

  FIG. 5 is a diagram showing the behavior of the reinforcing member 106 of FIG. 3 at the time of collision. FIG. 5A shows a state before the collision of the reinforcing member 106, and FIG. 5B shows the deformed reinforcing member 106 after the collision.

  In the reinforcing member 106, as shown in FIG. 3, the fixing point 132 a of the rear side fixing portion 116 is located on the vehicle front side with respect to the intersection C, and the rear side fixing portion 116 is more main body portion than the front side fixing portion 120. The inclination angle of 114 with respect to the reference direction D is large. Moreover, the rear side fixing | fixed part 116 has the weak part 142 shown in FIG.4 (b).

  For this reason, in the case of the collision shown in FIG. 5 (b), the reinforcing member 106 is reliably transmitted with the load to the rear side fixing portion 116, deformed by receiving the load on the lower side of the vehicle, and generates a moment toward the rear side of the vehicle. Then, the weak part 142 is reliably deformed by receiving the load. As a result, when the reinforcing member 106 receives a load at the time of collision, as shown in FIG. 5B, the rear side fixing portion 116 bends toward the rear side of the vehicle starting from the fragile portion 142, and the hood inner panel. It deforms so as to approach 104. Therefore, the reinforcing member 106 absorbs the impact energy at the time of the collision, thereby reducing the injury value for the colliding pedestrian and ensuring the pedestrian protection performance.

  FIG. 6 is a diagram schematically showing the reinforcing member 106 of FIG. 2 and the reinforcing member 200 of the comparative example. The chain lines E and F shown in FIGS. 6A and 6B indicate the sizes of base materials necessary for cutting out the reinforcing members 106 and 200, respectively.

  As shown in FIG. 6A, the reinforcing member 106 has the rear-side fixing portions 116 and 118 before being bent extending in the openings 122 and 124 of the main body portion 114 in a cantilever shape. Exists in the range. Therefore, when the main body 114, the front fixing part 120, and the rear fixing parts 116, 118 are formed from a base material, the base material has an area for the rear fixing parts 116, 118 existing within the range of the main body part 114. There is no need to prepare it separately. That is, the base material only needs to have a size that can cover the main body 114 and the front fixing portion 120. Here, as shown in FIG. 6A, the size of the base material is a dimension La in the vehicle front-rear direction and a dimension Lb in the vehicle width direction.

  As shown in FIG. 6B, the reinforcing member 200 of the comparative example has rear-side fixing portions 202 and 204 that are not bent and extend from the rear edges 128 and 130 of the main body portion 206 to the rear of the vehicle. It differs from the reinforcing member 106 of the present embodiment in that it exists outside the range.

  In the comparative example, when the reinforcing member 200 is formed from a base material, the base material has a size that can cover the main body portion 206 and the front side fixing portion 120, and the rear side fixing portion 202 that exists outside the range of the main body portion 206. It is necessary to prepare an area for 204 separately.

  As a result, the size of the base material in the comparative example, as shown in FIG. 6 (b), the dimension in the vehicle width direction is the same as the size of the base material of the reinforcing member 106, but the dimension Lb is sufficient. Is the dimension Lc. The dimension Lc is obtained by adding the dimension Ld in the vehicle front-rear direction of the rear fixing portions 202 and 204 of the reinforcing member 200 to the dimension La in the vehicle front-rear direction of the base material of the reinforcing member 106 of the present embodiment. That is, in the comparative example, when the reinforcing member 200 is cut out from the base material, it is necessary to separately prepare areas for the rear fixing portions 202 and 204 that exist outside the range of the main body portion 206, so the size of the base material is large. turn into.

  On the other hand, in the present embodiment, when the reinforcing member 106 is cut out from the base material, it is not necessary to prepare a region for the rear fixing portions 116 and 118 existing in the range of the main body 114. The size can be reduced, the amount of material used can be reduced, and the weight and cost can be reduced.

  In the above embodiment, the main body 114 has the two openings 122 and 124 by being separated by the bridging portion 126, but is not limited thereto. As an example, the main body part 114 may have one opening without the bridging part 126, or may have three or more openings with a plurality of bridging parts 126. Further, the number of rear-side fixing portions 116 and 118 is not limited to two, and one or three are provided as long as they are provided at the rear edge of each opening and are within the range of the main body portion 114 before being bent at the rear edge. There may be more than one. Even in such a case, when the reinforcing member is cut out from the base material, it is not necessary to separately prepare a region for the rear fixing portion existing in the range of the main body 114, and therefore the size of the base material can be reduced. .

  As mentioned above, although the suitable Example of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this example. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  The present invention can be used for a vehicle front hood.
