[ embodiment 1 ]
Fig. 1 to 4 show a structure of a vehicle body front portion according to embodiment 1 of the present invention. As shown in fig. 1 and 2, a vehicle body front portion 1 having a structure according to embodiment 1 of the present invention includes, as main members of an outer panel: a hood panel (hood outer panel) 2 disposed above the front portion 1 of the vehicle body and constituting a front openable/closable front hood that covers an upper portion of an engine room or a motor room; fender panels 3 of a front fender, which are disposed on the left and right sides outside the engine cover panel 2 in the vehicle width direction; a cowl top (cowl top outer) 4 made of a metal plate, which is disposed on the vehicle body rear side of the engine cover panel 2 and extends in the vehicle body width direction; a vehicle body side outer panel (front pillar outer panel) 5 that is disposed on the vehicle body rear side of the fender panel 3 and the cowl top 4 and extends in the vehicle body vertical direction; and a door front end portion 6A of the front door 6, which is disposed along the vehicle body rear side of the fender panel 3 and the vehicle body side outer panel 5.
In the structure of the vehicle body front portion 1 of the present embodiment, as shown in fig. 1 and 2, a cowl side 7 made of a metal plate is disposed in a region R of a space portion surrounded by the hood panel 2, the fender panel 3, the cowl top 4, the vehicle body side outer panel 5, and the door front end portion 6A. The side portion of the cowl side 7 is adjacent to the hood panel 2, the fender panel 3, and the cowl top 4, and is also adjacent to at least one (both in the present embodiment) of the body side outer panel 5 and the door front end portion 6A. That is, the side portions of the cowl side 7 are arranged in parallel with the end portions of the peripheral components positioned on the front, rear, left, and right sides of the cowl side 7 with a slight gap therebetween.
The following points can be mentioned as the reason for disposing the cowl side 7. That is, since the cowl side 7 does not have an inner panel as in the case of the front hood, the cost and weight can be reduced. Further, the cowl side 7 is configured to be detachable from the vehicle body front portion 1 in consideration of the service level when the windshield is replaced, and the cowl side 7 is configured not to fall off even if an impact load is applied from above the vehicle body, so that the impact energy can be absorbed reliably. Further, since the cowl side 7 is divided independently of the fender panel 3, the cowl side 7 can partially increase the plate thickness, can further absorb the impact energy, contributes to the molding of the fender panel 3, and contributes to the improvement of the moldability of the fender panel 3. Further, since the cowl side 7 is set by the sheet metal member and can be matched with the peripheral components, the vehicle body front portion 1 having good appearance quality can be secured.
As shown in fig. 2 to 4, an absorber 8 having a letter L shape is disposed below the cowl side panel 7 and the cowl top 4 in the present embodiment, and the absorber 8 is attached to a cowl side member 11 of the vehicle body frame member. The absorber 8 is additionally provided to further improve the impact absorption performance at the peripheral structure of the cowl side 7 where the hood panel 2, the fender panel 3, the cowl top 4, and the like are arranged. Therefore, the absorber 8 is formed in an L-shape when viewed from the front of the vehicle body by bending the upper portion of a rectangular plate-like body made of a metal plate having a predetermined vehicle body front-rear width at substantially right angles, and the absorber 8 has a horizontal surface portion 81 and a vertical surface portion 82, the horizontal surface portion 81 is disposed on the upper side in the vehicle body vertical direction, the vertical surface portion 82 is disposed on the lower side of the horizontal surface portion 81, and the lower end portion thereof is joined to the cowl side member 11 by welding. A reinforcing rib 82a extending in the vehicle vertical direction is formed so as to protrude from the center position of the vertical surface portion 82 in the vehicle longitudinal direction, and the rigidity of the absorber 8 is controlled by the height of the reinforcing rib 82 a. The protruding height of the reinforcing rib 82a is set to be lower as the welding surface toward the vertical surface portion 82, that is, the lower end portion, is moved, and the reinforcing rib 82a is configured to bend the absorber 8 at the root portion when the horizontal surface portion 81 receives an impact load.
As shown in fig. 1, 2, and 4, the cowl side 7 of the present embodiment includes a side plane 71 facing the vehicle body side and an upper plane 72 facing the vehicle body upper side. The side flat surface 71 and the upper flat surface 72 are formed in an L shape when viewed from the front of the vehicle body by bending the middle portion of the cowl side 7 in the vehicle width direction, and are disposed at such a height position as to be continuous with the surfaces of the hood panel 2, the fender panel 3, the cowl top 4, the vehicle body side outer panel 5, and the door front end portion 6A. The cowl side 7 is disposed such that the lower side edge portion 7A of the side flat surface 71 is adjacent to the fender panel 3, and the side edge portion 7B of the upper flat surface 72 is adjacent to the cowl top 4. The cowl side 7 is disposed so that a side portion 7C extending in the vehicle body up-down direction and the vehicle body width direction is adjacent to the hood panel 2, a side portion 7D extending in the vehicle body width direction is adjacent to the vehicle body side outer panel 5, and a side portion 7E extending along the front end portion of the door is adjacent to the door front end portion 6A.
Thus, in the structure of the vehicle body front portion 1 of the present embodiment, the cowl side 7, which is one member, is configured such that the parting step with the side portion 7A to the side portion 7E in each direction can be adjusted, and the work of adjusting the parting step is simplified without directly adjusting the parts with respect to the parting step of the hood panel 2, the fender panel 3, the cowl panel 4, the vehicle body side outer panel 5, and the door front end portion 6A. Further, when an impact load is applied from above the vehicle body to the cowl side 7 formed in the letter L shape as viewed from the front of the vehicle body, the cowl side 7 can be bent and deformed so as to be folded about a boundary portion between the side flat surface 71 and the upper flat surface 72, and the impact load can be effectively absorbed.
As shown in fig. 3, the fender panel 3 of the present embodiment is provided with a 1 st retainer 9 in the vehicle body longitudinal direction, the 1 st retainer 9 having a pair of front and rear projecting engaging claws including a projecting engaging claw 91 and a projecting engaging claw 92 projecting upward from the vehicle body, the projecting engaging claw 91 being disposed at a position closer to the vehicle body front side upward at a lower portion of the 1 st retainer 9, and the projecting engaging claw 92 being disposed at a position closer to the vehicle body rear side upward at a lower portion of the 1 st retainer 9. The 1 st retainer 9 is formed into a rectangular frame-like body when viewed from the vehicle body side, and the 1 st retainer 9 is attached to the upper flat surface 3a and the upper vertical wall surface 3b of the fender panel 3 on the vehicle body rear side in order to retain the cowl side panel 7. Further, since the 1 st retainer 9 is a resin-made component and is attached to the fender panel 3 by a bolt, a clip, or the like, the 1 st retainer 9 is configured to be finely adjustable in accordance with the production accuracy of the fender panel 3, and to be capable of adjusting the positional relationship with the cowl side 7.
A pair of front and rear holes (not shown) that can engage with the projection engagement claws 91 and 92 are provided at positions corresponding to the projection engagement claws 91 and 92 at the lower portion of the side flat surface 71 of the cowl side panel 7. The cowl side 7 is engaged with the protruding engagement claws 91 and 92 so as to be hooked in the hole, and is held in a state of being positioned in the 1 st holder 9 while being aligned with the fender panel 3 in the vehicle width direction. Thus, the parting step between the cowl side 7 and the fender panel 3 is adjusted, and the cowl side 7 can be easily assembled to the fender panel 3 via the 1 st retainer 9. Further, when an impact load is applied to the cowl side 7 from above the vehicle body, the shapes of the projecting engagement claws 91 and the projecting engagement claws 92 suppress the movement of the cowl side 7 toward below the vehicle body, and the projecting engagement claws 91 and the projecting engagement claws 92 are pressed so as to be more difficult to disengage from the hole portions (not shown), and also, do not disengage from the bending deformation of the cowl side 7, and can continuously absorb the impact load. Further, in order to prevent the cowl side 7 from being displaced downward of the vehicle body and coming off the projection engaging claws 91 and the projection engaging claws 92 when an impact load is applied to the upper flat surface 72 of the cowl side 7 from above the vehicle body, the projection engaging claws 91 and the projection engaging claws 92 project above the hole portions by a predetermined projection length.
As shown in fig. 3 and 4, a mounting bracket 40 made of a metal plate is provided at an end portion 4a of the cowl top 4 in the vehicle width direction in the present embodiment, and the mounting bracket 40 extends in the vehicle longitudinal direction and has a downward locking claw 41. The mounting bracket 40 includes: a vertical piece 40a whose upper portion is welded to an end portion 4a of the cowl top 4 in the vehicle width direction, the end portion 4a being bent downward; and a horizontal piece 40b fixed to the upper flange portion 72a of the cowl side 7 by a clip or the like. The upper flange portion 72a is formed at an upper portion of the cowl side 7, and extends inward in the vehicle width direction from an inner end portion 7a of the upper flat surface 72 bent downward, and a portion on the tip end portion side of the upper flange portion 72a is fixed to the cowl side bracket 12 that is adjustable in position in the vehicle longitudinal direction and the vehicle width direction by a bolt 13, a clip 14, and the like.
As shown in fig. 5, a resin-made 2 nd retainer 10 formed to be larger than the front-rear length dimension of the locking claw 41 is provided on the upper portion of the cowl side panel 7, and the 2 nd retainer 10 is fixed to the upper surface of the upper flange portion 72a of the cowl side panel 7 at a position corresponding to the locking claw 41. The cowl side 7 is held by the mounting bracket 40 by inserting and locking the locking claw 41 into the 2 nd retainer 10.
Thus, the end portion 4a of the cowl top 4 in the vehicle width direction is reliably restrained by the mounting bracket 40 along the vehicle body front-rear direction, and adjustment of the parting step of the cowl side panel 7 and the cowl top 4 becomes simple. Further, when the cowl side 7 is bent and deformed, the cowl side 7 is more reliably locked to the mounting bracket 40 by the impact load from above the vehicle body, and the cowl side 7 can continuously absorb the impact load without being separated from the mounting bracket 40.
On the other hand, in the structure of the vehicle body front portion 1 of the present embodiment, as shown in fig. 2 to 4, the mounting bracket 40 that joins the inner end portion 7a of the cowl side panel 7 and the end portion 4a of the cowl top 4 in the vehicle width direction is arranged in the vehicle body longitudinal direction above the horizontal surface portion 81 of the absorber 8. The mounting bracket 40 has an extended portion 40c located on the vehicle body front side of the upper flange portion 72a of the cowl side panel 7, and the extended portion 40c is a part of the horizontal piece 40 b. Thus, when the cowl side 7 and the cowl top 4 receive an impact load, the mounting bracket 40 moves toward the lower side of the vehicle body, the horizontal surface portion 81 of the absorber 8 is reliably pressed by the rigidity of the mounting bracket 40, and the absorber 8 absorbs the impact load while falling toward the inner side of the vehicle body.
Therefore, as shown in fig. 3 and 4, the horizontal surface portion 81 of the absorber 8 is configured to extend toward the vehicle body inner side by a predetermined length, and is disposed so as to overlap the horizontal piece 40b of the mounting bracket 40 when viewed from above the vehicle body at a position where the extension portion 40c of the mounting bracket 40 of the upper flange portion 72a of the cowl side panel 7 is not disposed, so that the impact load from above the vehicle body can be received over a wide range.
In the structure of the vehicle body front portion 1 of the present embodiment, as shown in fig. 2 and 3, a resinous cowl cover 42 is disposed on the vehicle body lower side of the cowl top 4. The front cowl 42 is provided with a vertical wall 42a facing the vehicle body side, the vertical wall 42a is adjacent to a horizontal surface portion 81 of the absorber 8, and a tip end portion of the horizontal surface portion 81 and the vertical wall 42a are disposed with a space therebetween in the vehicle width direction. When the absorber 8 is deformed, the top end of the horizontal plane portion 81 is configured to contact the vertical wall 42a of the front cover 42.
Thus, when the absorber 8 receives an impact load from above the vehicle body, the absorber 8 absorbs the impact load while tilting toward the inside of the vehicle body, and the leading end portion of the horizontal plane portion 81 contacts the vertical wall 42a of the front cowl 42 to break the vertical wall 42a, thereby absorbing the impact load in the process of the breaking.
As described above, the structure of the vehicle body front portion 1 according to embodiment 1 of the present invention includes: a hood panel 2 disposed above the front portion 1 of the vehicle body; a fender panel 3 disposed on the vehicle body width direction outer side of the engine cover panel 2; and a cowl top 4 made of a metal plate, which is disposed on the vehicle body rear side of the hood panel 2 and extends in the vehicle body width direction. A cowl side 7 is disposed in a region R surrounded by the hood panel 2, the fender panel 3, and the cowl top 4. Further, an absorber 8 having a letter L shape is disposed below the cowl side panel 7 and the cowl top 4, the absorber 8 is attached to a cowl side member 11 of the vehicle body frame member, and the absorber 8 has a horizontal plane portion 81 on the upper side.
That is, in the structure of the vehicle body front portion 1 of the present invention, when an impact load is applied to the cowl side 7 and the cowl top 4 from above the vehicle body, the boundary between the inner end portion 7a of the cowl side 7 and the end portion 4a of the cowl top 4 in the vehicle width direction deforms and moves downward of the vehicle body, the horizontal surface portion 81 of the absorber 8 in the letter L shape located below the cowl side 7 and the cowl top 4 is pressed, and the absorber 8 falls down toward the inside of the vehicle body from the root of the vertical surface portion 82, so that the absorber 8 can be reliably displaced as a whole. Therefore, according to the structure of the vehicle body front portion 1 of the present invention, the impact load can be sufficiently and effectively absorbed in the process of displacement of the absorber 8, and the impact absorption performance can be improved as compared with the conventional structure. Further, since the absorber 8 is disposed below the vehicle body of the cowl side 7 and the cowl top 4, good design of the vehicle body front portion 1 can be ensured.
In the structure of the vehicle body front portion 1 of the present embodiment, the cowl side panel 7 has a side plane 71 facing the vehicle body side and an upper plane 72 facing the vehicle body upper side, which are formed by bending an intermediate portion in the vehicle width direction. The cowl side 7 is disposed such that the lower side edge portion 7A of the side flat surface 71 is adjacent to the fender panel 3, and the side edge portion 7B of the upper flat surface 72 is adjacent to the cowl top 4. Further, a mounting bracket 40 for joining the cowl side 7 and the cowl top 4 is disposed above the horizontal surface portion 81 of the absorber 8.
That is, in the structure of the vehicle body front portion 1 of the present embodiment, when the cowl side 7 and the cowl top 4 receive an impact load, the mounting bracket 40 moves toward the vehicle body lower side, and the horizontal surface portion 81 of the absorber 8 is inevitably pressed by the rigidity of the mounting bracket 40, so that the absorber 8 surely absorbs the impact load while falling toward the vehicle body inner side. In particular, in the case where the horizontal surface portion 81 of the absorber 8 extends inward of the vehicle body by a predetermined length and is disposed so as to overlap the horizontal piece 40b of the mounting bracket 40 when viewed from above the vehicle body at a position where the extension portion 40c of the mounting bracket 40 of the upper flange portion 72a of the cowl side panel 7 is not disposed, the impact load from above the vehicle body can be received over a wide range. In addition, in the structure of the vehicle body front portion 1 of the present embodiment, when an impact load is applied from above the vehicle body to the cowl side panel 7 formed in the letter L shape as viewed from the front of the vehicle body, the absorber 8 deforms in synchronization with the deformation while the cowl side panel 7 absorbs the impact load while performing bending deformation with the boundary portion between the side flat surface 71 and the upper flat surface 72 as the center in a folded manner, and therefore, a synergistic effect is obtained, and the impact load can be absorbed more effectively.
In the structure of the vehicle body front portion 1 according to the present embodiment, the horizontal portion 81 of the absorber 8 extends toward the vehicle body inner side. A resin cowl cover 42 is disposed below the cowl top 4, and a vertical wall 42a facing the vehicle body side is provided on the cowl cover 42, and the vertical wall 42a is adjacent to the horizontal plane portion 81.
Therefore, in the structure of the vehicle body front portion 1 of the present embodiment, when the L-letter-shaped absorber 8 having the horizontal plane portion 81 on the upper side receives an impact load from above the vehicle body, the absorber 8 displaces while falling toward the inside of the vehicle body, and therefore the absorber 8 can absorb the impact load during its displacement. Further, since the tip end portion of the horizontal surface portion 81 comes into contact with the vertical wall 42a of the front cover 42 to break the vertical wall 42a, the impact load can be absorbed in the process of the breaking. Therefore, in the structure of the vehicle body front portion 1 of the present embodiment, not only the impact load from above the vehicle body can be absorbed by the absorber 8, but also the impact load from above the vehicle body can be absorbed by the interaction between the absorber 8 and the cowl 42, and therefore, the impact absorption performance can be improved.
[ 2 nd embodiment ]
Fig. 5 shows a structure of a vehicle body front portion according to embodiment 2 of the present invention. Note that the same portions as those described in embodiment 1 above are denoted by the same reference numerals, and redundant description thereof is omitted.
In the structure of the vehicle body front portion 1 according to embodiment 2, as shown in fig. 5, an outer absorber 8A having an L-shape is further provided on the vehicle body outer side of the absorber 8. The outer absorber 8A is formed to have a smaller overall size than the absorber 8 of embodiment 1, but has substantially the same shape as the absorber 8 of embodiment 1. That is, the outer absorber 8A has a flat surface portion 81A and a vertical surface portion 82A, the flat surface portion 81A is disposed on the upper side in the vehicle body vertical direction, the vertical surface portion 82A is disposed on the lower side of the flat surface portion 81A, and the lower end portion thereof is joined to the vertical surface portion 82 of the absorber 8 by welding. However, the flat surface portion 81A of the outer absorber 8A extends outward of the vehicle body at a position higher than the horizontal surface portion 81 of the absorber 8, and is disposed outward in the vehicle width direction. The flat surface portion 81A of the outer absorber 8A is inclined downward toward the front of the vehicle body.
As described above, in the structure of the vehicle body front portion 1 according to embodiment 2, the outer absorber 8A having the letter L shape is further provided on the vehicle body outer side of the absorber 8, and the outer absorber 8A has the flat surface portion 81A on the upper side, and the flat surface portion 81A is disposed toward the vehicle body width direction outer side, so that it is possible to promote absorption of the impact load from above the vehicle body. Further, since the flat surface portion 81A of the outer absorber 8A of embodiment 2 is inclined downward as it goes toward the front of the vehicle body, the orientation of the flat surface portion 81A can be matched with the direction of the impact load, and the operation of matching the orientation of the horizontal surface portion 81 of the inner absorber 8 with the direction in which the mounting bracket 40 is continuously lowered can be combined to cope with the direction of the input impact load. Other effects are the same as those of embodiment 1.
While the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made based on the technical idea of the present invention.
For example, in the above-described embodiment, the cowl side 7 is disposed in the region R of the space portion surrounded by the hood panel 2, the fender panel 3, the cowl top 4, the vehicle body side outer panel 5, and the door front end portion 6A, but the cowl side 7 may be disposed in at least the region of the space portion surrounded by the hood panel 2, the fender panel 3, and the cowl top 4.
