Description

  The present invention relates to a vehicle front hood that is disposed above an engine room at a front portion of a vehicle body.

  In a vehicle such as an automobile, an engine room is provided at the front of the vehicle body, and a vehicle front hood (hereinafter simply referred to as a front hood) is disposed above the engine room. An air intake may be set in the front hood depending on the vehicle type. The air intake is a member that is attached to an opening provided in the front hood, and that introduces outside air into the engine room by connecting a duct and an opening provided in the engine room of the vehicle.

  The above-mentioned front hood may be ridden by the collided body when the vehicle collides with the collided body, and particularly when the collided body is a pedestrian, the head of the pedestrian is in contact with the front hood. There is. For this reason, the front hood is designed so as to absorb the collision energy by deformation and to reduce the impact load on the collision target (particularly a pedestrian). Therefore, even when an air intake is set in the front hood, it is necessary to be able to have an impact energy absorption performance equivalent to that in the case where the air intake is not set. In other words, high impact energy absorption performance is also required for air intake.

  Therefore, in Patent Document 1, for example, a hood air intake (air intake) disposed on a hood is formed into a rectangular cylindrical shape having an upper wall portion, a lower wall portion, and a side wall portion, and a thin wall portion is formed on the side wall portion. Yes. According to Patent Document 1, when a collision target that is in contact with the upper wall portion of the air intake presses the upper wall portion downward, the side wall portion and thus the air intake is easily deformed starting from the thin wall portion. The impact load acting on the collision object can be reduced.

  Here, as described above, the air intake is a member (air introduction member) originally intended to introduce the outside air into the engine room, but in recent years, even if it is not necessary to introduce the outside air, Intake-shaped exterior members (dummy air intakes) tend to be adopted as the design of the front of the vehicle body. In such a case, unlike the case where the air intake is used as an air introduction member as usual, it is difficult to improve the rigidity using the rigidity of peripheral members such as a duct. For this reason, when adopting a dummy air intake, rigidity is improved by attaching an interior member to the inner surface thereof.

  By the way, among the structures arranged in the engine room in the front part of the vehicle body, the engine (engine body) is particularly hard, so that when the vehicle collides with the engine, the collided body is damaged greatly. For this reason, it is desirable to ensure a sufficient distance between the front hood and the engine in the vicinity of the engine. However, when there are restrictions due to the design of the front hood, the layout of structures in the engine room, etc., it is not always possible to ensure a sufficient distance between the front hood and the engine. In such a case, it is preferable to provide a structure for absorbing an impact in an air intake disposed in the vicinity of the engine or an interior member attached thereto, but simply providing an impact absorbing structure in the entire air intake or the interior member, The increase in the weight of those members and the increase in cost will be caused.

  In view of such a problem, the present invention can absorb a shock at the time of collision while minimizing an increase in weight and cost, and can reduce an impact load on a collision target. The object is to provide a front hood for a vehicle that can be used.

  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 disposed above an engine room at the front of a vehicle body, and includes an outer surface of the vehicle front hood. A hood outer panel having an opening, a hood inner panel disposed inside the hood outer panel, having an opening in a region corresponding to the opening of the hood outer panel and constituting an inner surface of the front hood for the vehicle, and a hood An exterior member attached to the hood outer panel so as to cover the edge of the opening with an air intake shape having a ventilation hole at a position corresponding to the opening of the outer panel, and a vehicle width direction that is attached to the inner surface of the exterior member and closes the ventilation hole An interior member having at least a wall surface portion extending from the back side of the wall surface portion toward the rear of the vehicle body. The length of the rib in the vehicle front-rear direction is such that the distance between the hood inner panel and the front end of the structure disposed in the engine room is a predetermined distance in a cross-sectional view seen from the side of the vehicle body. If the distance is less than the distance, the distance is extended to the rear of the vehicle body from the distance of a predetermined distance or more.

  According to the above configuration, in the interior member, a structure disposed in the engine room, for example, a location where the distance between the front end of the engine and the hood inner panel is less than a predetermined distance, that is, a location where the distance between the engine and the hood inner panel is short. Then the rib is set longer. As a result, the rib and the engine can be brought into contact with each other at an earlier stage than the other parts at the time of collision with the colliding object, and the impact energy from the colliding object is absorbed by the deformation and crushing of the rib due to this contact, It is possible to reduce the impact load on the collision target. On the other hand, the rib is set to be short at a place where the distance between the front end of the engine and the hood inner panel is a predetermined distance or more, that is, a place where the distance between the engine and the hood inner panel is long. Thereby, in the location where the space | interval of the front end of an engine and a hood inner panel is fully maintained, weight reduction and cost reduction can be aimed at, and a type | mold structure can be simplified. Therefore, according to the above configuration, it is possible to satisfactorily absorb the impact at the time of collision while minimizing the increase in weight and cost, and it is possible to reduce the impact load on the collision target. .

  The front edge and rear edge of the opening of the hood outer panel have a height difference, and the exterior member includes a front surface extending from the vicinity of the front edge of the opening of the hood outer panel toward the rear of the vehicle body, and the vicinity of the rear edge of the opening. A bottom surface portion that extends from the lower end of the wall surface portion and is disposed below the front surface of the exterior member and above the hood inner panel in the vehicle height direction. And a flange extending toward the rear of the vehicle body from the upper end of the wall surface portion, and the interior member has a notch portion cut out toward the front near the rear end of the flange, and a fixture near the front end of the bottom surface portion. The exterior member has a claw portion protruding downward at a position corresponding to the notch portion, and the fixture is inserted at a position corresponding to the interior side insertion hole. It has an exterior side insertion hole, Part vicinity of the rear end is fixed to the exterior member by the abutted to the notch, it may near the front end is fixed to the exterior member by inserting the fasteners on the exterior side insertion hole and an interior side insertion hole.

  According to this configuration, the interior member is fixed to the exterior member more firmly in the vicinity of the front end than in the vicinity of the rear end. For this reason, when the exterior member is deformed by the collision with the collision object, the fixing point with the exterior member near the rear end of the interior member is removed, and the interior member rotates downward about the fixed point near the front end. Move to. As a result, the ribs described above can be brought into contact with the engine (the structure in the engine room) and deformed more quickly, so that the impact energy absorption performance can be further improved.

  The exterior member has a claw portion erected downward from the back surface of the front surface, and the interior member has a claw receiving hole at a position corresponding to the claw portion of the exterior member on the bottom surface portion. The interior member may be fixed to the exterior member by being fitted into the hole. Thereby, fixation in the front part of an interior member and an exterior member becomes still stronger.

  ADVANTAGE OF THE INVENTION According to this invention, for the vehicle which can absorb the impact at the time of a collision favorably and can reduce the impact load to a to-be-collised body, keeping an increase in a weight and an increase in cost to the minimum. Front hood can be provided.

  As shown in FIG. 2, the wall surface portion 140 a of the present embodiment is a vertical wall extending in the vehicle height direction from below the rear surface 134 b of the exterior member 130. Specifically, the outer panel 110 of the present embodiment has a height difference between the front edge 112 and the rear edge 114 of the opening 110a, and the front surface 134a and the rear surface of the exterior member 130 are adapted to the height difference. The direction 134b also has a height difference. In such a case, since the ventilation hole 132 is provided in the space in the vehicle height direction of the front surface 134a and the rear surface 134b, the ventilation hole 132 can be suitably closed by using the wall surface portion 140a as a vertical wall.

  As shown in FIG. 2, in the interior member 140, a bottom surface portion 140b that extends from the lower end of the wall surface portion 140a and is disposed below the front surface 134a of the exterior member 130 and above the inner panel 120 in the vehicle height direction. Is provided. Flanges 140c and 140d projecting forward of the vehicle body are formed on the side edges of the bottom surface portion 140b and the wall surface portion 140a. Thereby, since the edge of the interior member 140 becomes a shape along the inner surface of the exterior member 130, a gap between them can be reduced, and the rigidity of the interior member 140 can be improved.

  As shown in FIG. 4, claw receiving holes 142 a, 142 b, 142 c, and 142 d are formed on the bottom surface portion 140 b at positions corresponding to the claw portions 137 a to 137 d of the exterior member 130. Further, screw holes 143a and 143b are formed in the vicinity of the front end of the bottom surface portion 140b as interior-side insertion holes through which the screw 160 (see FIG. 6B), which is a fixture, is inserted when attached to the exterior member 130. . On the other hand, in the interior member 140 of the present embodiment, a flange 141 extending from the upper end of the wall surface portion 140a toward the rear of the vehicle body is provided, and in the vicinity of the rear end of the flange 141, a notch portion cut out toward the front. 142e, 142f, 142g, and 142h are formed.

In order to facilitate understanding, the position of the AA cross section shown in FIG. 1 is also shown in FIG. 5, and FIG. 6A shows the outer panel 110 and the inner panel 120.

  When the above-described claw portions 137a to 137d are fitted into the claw receiving holes 142a to 142d and the claw portions 137e to 137h (see FIG. 3B) are fitted into the notches 142e to 142h, the exterior member 130 is shown in FIG. The interior member 140 is attached to the back surface of the. At this time, as shown in FIG. 6A, the interior member 140 has claw receiving holes 142a to 142d (FIG. 6A shows the claw receiving holes 142b), and claw portions 137a to 137d (FIG. 6A). In FIG. 6, the notch portions 137 b are illustrated, and the notch portions 142 e to 142 h (the notch portion 142 f is illustrated in FIG. 6A) are abutted against the claw portions 137 e to 137 h (the claw portion 137 f is illustrated in FIG. 6A). It is fixed in the state.

  As shown in FIG. 6B, the screw 160 is inserted into the screw holes 143a and 143b (the screw hole 143a is shown in FIG. 6B) and the bosses 139a and 139b (the boss 139a is shown in FIG. 6B). The interior member 140 is fixed to the exterior member 130 by inserting. That is, in this embodiment, the interior member 140 is fixed to the exterior member 130 by abutting the claw portions 137e to 137h against the notches 142e to 142h in the vicinity of the rear end, and the claw portions 137a to 137d in the vicinity of the front end. In addition to fitting into the holes 142a to 142d, the screw 160 (fixing tool) is inserted into the bosses 139a and 139b (exterior side insertion holes) and the screw holes 143a and 143b (interior side insertion holes) to be fixed to the exterior member 130. Has been. As a result, the interior member 140 is more firmly fixed to the exterior member 130 in the vicinity of the front end than in the vicinity of the rear end. Therefore, as will be described later, ribs 144a and 144b formed on the interior member 140 at the time of collision with the collision target are described. And the structure in the engine room (in this embodiment, the engine 170) can be brought into contact with each other promptly.

  After the interior member 140 is attached as described above, the exterior member 130 is attached to the front hood 100 (the outer panel 110 and the inner panel 120). First, in the tower-shaped boss 139 c, the front surface 134 a (front portion) of the exterior member 130 is inserted by the clip 150 into the long hole 120 b that is long in the front-rear direction of the inner panel 120. Thereby, the exterior member 130 is temporarily fixed to the inner panel 120. Further, in the claw portions 137e to 137h, substantially L-shaped L-shaped portions 137i, 137j, 137k, and 137l are provided on the vehicle rear side (see FIG. 3B). As a result, as shown in FIG. 6A, L-shaped portions 137 i to 137 l (L-shaped portion 137 j is illustrated in FIG. 6B) abuts against the rear edge 114 of the outer panel 110.

  Then, by inserting a screw (not shown) through the bosses 139d to 139i, the vicinity of the front end of the exterior member 130 is fixed to the front edge 112 of the outer panel 110 as shown in FIG. On the other hand, in the vicinity of the rear end of the exterior member 130, the L-shaped portions 137i to 137l of the claw portions 137e to 137h are fixed to the outer panel 110 by holding the rear edge 114 of the abutted outer panel 110 as described above. (See FIG. 6A).

  Here, ribs are formed on the back surface of the interior member 140 described above as shown in FIG. Specifically, as shown in FIG. 2, a rib 144 a is provided on the wall surface 140 a of the interior member 140 from the back surface (back side) toward the rear of the vehicle body. Thereby, the rigidity of the interior member 140 and the exterior member 130 to which it is attached can be improved. Further, as shown in FIG. 4B, in addition to the rib 144a, a rib 144b intersecting with the rib 144a is erected on the back surface of the wall surface portion 140a of the present embodiment so as to face the rear of the vehicle body. That is, on the back surface of the wall surface portion 140a, lattice-shaped ribs composed of two-way ribs 144a and 144b are formed. Thereby, the intensity | strength with respect to the impact from a some direction can be obtained, and it becomes possible to obtain much higher rigidity.

  In the present embodiment, three rows of ribs 144a and thirteen rows of ribs 144b are provided on the wall surface portion 140a. However, this number is merely an example and is not limiting. The number of the ribs 144a and 144b can be arbitrarily set. By changing the number of the ribs 144a and 144b, the balance between the deformability and the rigidity can be easily adjusted as necessary. In the present embodiment, the ribs 144a and 144b are provided in a lattice shape, but the present invention is not limited to this, and other shapes such as a honeycomb structure and a columnar shape can also be adopted.

  Furthermore, in the present embodiment, the lengths of the ribs 144a and 144b in the vehicle front-rear direction differ depending on the distance between the inner panel 120 and the front end of the structure disposed in the engine room in a cross-sectional view as viewed from the side of the vehicle body. It is Specifically, the length of the ribs 144a and 144b in the vehicle front-rear direction is such that the distance between the inner panel 120 and the front end of the structure disposed in the engine room is less than a predetermined distance when viewed from the side of the vehicle body. Then, the space | interval is extended in the vehicle body back rather than the location beyond a predetermined distance. Hereinafter, the engine 170 (see FIG. 2) will be described as an example of the structure disposed in the engine room.

  First, as shown in FIG. 4B, the interior member 140 of the present embodiment is divided into five regions, region D, region E1, region E2, region F1, and region F2, in the vehicle width direction. Of these areas, the area D is an area disposed in the vicinity of the most projecting portion of the engine 170, and the interval L1 (see FIG. 2) between the inner panel 120 and the front end of the engine 170 is less than a predetermined distance. . Regions E1 and E2 are regions that are arranged in the vicinity of a region where engine 170 does not protrude so much, and a distance L2 (see FIG. 6A) between inner panel 120 and the front end of engine 170 is a predetermined distance or more. The areas F1 and F2 are places where the engine 170 does not exist behind the inner panel 120.

  In the region D, the ribs 144a and 144b are extended rearward of the vehicle body from the regions E1 and E2. That is, the length of the rib 144a in the region D in the vehicle front-rear direction (see FIG. 2) is set to be longer than the length of the rib 144a in the regions E1 and E2 (see FIG. 6A). Further, the ribs themselves are not provided in the regions F1 and F2 (see FIG. 4B).

  FIG. 7 is a diagram for explaining the deformation of the exterior member 130 and the interior member 140 at the time of collision of the collision object. When an impacted body (not shown) collides from above the front hood 100 and an impact in the direction of the white arrow is applied to the exterior member 130 as shown in FIG. 7A, as shown in FIG. It deform | transforms so that the back surface 134b of the exterior member 130 may be crushed below. Then, by being pushed by the deformed exterior member 130, the interior member 140 falls toward the rear of the vehicle body, and ribs 144a and 144b (formed on the back surface of the wall surface portion 140a of the interior member 140 as shown in FIG. In FIG. 7, only the rib 144a is in contact with the engine 170. As a result, the ribs 144a and 144b are deformed and crushed, so that the impact energy from the impacted body is absorbed and the impact load on the impacted body is reduced.

  At this time, as described above, in the present embodiment, in the interior member 140, in the portion (region D) where the distance between the front end of the engine 170 (structure disposed in the engine room) and the inner panel 120 is less than a predetermined distance. The ribs 144a and 144b are set longer. As a result, the ribs 144a and 144b can be brought into contact with the engine 170 in the region D earlier than the regions E1 and E2 when the collision target collides with the front hood 100. Therefore, the impact energy is absorbed quickly and reliably at a place where the distance between the engine 170 and the inner panel 120 is short as in the region D, and the impact load on the collision target can be effectively reduced.

  In particular, in the present embodiment, as described above, the vicinity of the rear end of the interior member 140 is only fixed to the exterior member 130 by abutting the claw portions 137e to 137h against the notches 142e to 142h. For this reason, the deformation of the exterior member 130 makes it easier for the rear end of the interior member 140 and the exterior member 130 to be fixed, and the impact of the impacted body causes the interior member 140 to move downward with a fixed point near the front end as a center. Move to rotate. As a result, the ribs 144a and 144b can be brought into contact with the engine 170 and deformed more quickly, so that the impact energy absorption performance can be further improved.

  On the other hand, in the interior member 140, the ribs 144 a and 144 b are set to be short at locations where the distance between the front end of the engine 170 and the inner panel 120 is a predetermined distance or more (regions E 1 and E 2). Where the distance from the inner panel 120 is sufficiently maintained, weighting by the ribs 144a and 144b is suppressed. Therefore, it is possible to achieve weight reduction, cost reduction, and simplification of the mold structure. Furthermore, in this embodiment, since the rib is abolished in the areas F1 and F2, which are places where the engine 170 is not disposed behind, the above-described effects can be further enhanced.

  As described above, according to the vehicle front hood (front hood 100) of the present embodiment, it is provided at a location where the distance between the front end of the engine 170 (structure disposed in the engine room) and the inner panel 120 is narrow. Good impact energy absorption performance can be obtained by the long ribs. On the other hand, weight reduction due to the ribs can be suppressed by a short rib provided at a portion where the distance between the front end of the engine 170 and the inner panel 120 is wide. Therefore, it is possible to satisfactorily absorb the impact at the time of collision while minimizing the increase in weight and cost, and it is possible to reduce the impact load on the collision target.

  In the above-described embodiment, the case where ribs are provided on the interior member 140 attached to the exterior member 130 used as a dummy has been described in detail. On the other hand, when the exterior member 130 is used as an air introduction member, the interior member 140 that closes the vent hole 132 is not naturally attached, and a duct (both not shown) connected to the intercooler disposed at the front of the vehicle body is provided. It is attached to the back surface of the member 130. In such a case, if a rib is provided around the opening provided on the side attached to the exterior member 130 in the duct or inside the opening so as not to block the opening, the wall surface portion of the present embodiment The same effects as those of the ribs 144a and 144b formed on the 140a can be obtained.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. 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.

  INDUSTRIAL APPLICABILITY The present invention can be used for a vehicle front hood that is disposed above the engine room at the front of the vehicle body.
