Japanese Patent Application Laid-Open No. 2010-188966

In the conventional end structure of a vehicle, a bumper beam that receives a load from the front-rear direction of the vehicle body is formed to have a substantially constant vertical width. For this reason, when an external object such as another vehicle moves relative to each other in the proximity direction, the area where the impact load can be stably received is limited, and the load input point from the external object is used. Local load concentration is likely to occur.

The problem to be solved is to provide a vehicle end structure capable of efficiently receiving an impact load input from the front-rear direction of the vehicle body while avoiding local load concentration.

The end structure of the vehicle body according to one embodiment of the present application includes left and right side frame members extending substantially along the vehicle front-rear direction and left and right side frame members extending substantially along the vehicle width direction at the front or rear of the vehicle body. A bumper beam supported across the side frame member is provided, and the bumper beam is provided in a beam main body portion coupled to the left and right side frame members and at least in a vehicle width direction central region of the beam main body portion. It is characterized by having an expansion portion extending in the vertical direction longer than the beam main body portion.

With the above configuration, when an external object moves relatively close to the outside in the front-rear direction of the vehicle body, the extension portion having a wide vertical width is likely to receive a load from the external object. Since the expansion part has a wider vertical width than the beam body part, the load can be efficiently received in a wide area and the load is concentrated locally as compared with the case where the load is received only by the beam body part. Can be prevented. Further, in the above configuration, the impact load input to the expansion portion can be transmitted to the left and right side frame members via the beam main body portion, so that the member located on the outside in the front-rear direction of the vehicle interior is a vehicle. It is possible to suppress the displacement in the room direction.

The expansion portion may be configured by a separate component from the beam main body portion and may be coupled to the beam main body portion.

In this case, since the beam main body portion and the expansion portion are composed of separate parts, the parts can be shared between the bumper beam having no expansion portion and the bumper beam having the expansion portion. Therefore, by adopting this configuration, it is possible to improve the production efficiency of parts.

The extended portion has an upward extending portion extending upward from the beam main body portion and a downward extending portion extending downward from the beam main body portion, and the downward extending portion and the upward extending portion. A notch is provided at the outer end in the width direction of any one of the vehicles.

In this case, the sensor, radar, or the like can be arranged in the notch provided in either the upward extension portion or the downward extension portion. Further, by arranging the sensor, radar, or the like inside the vehicle body in the front-rear direction with respect to the expansion portion, the sensor, radar, or the like can be protected by the expansion portion against an input load from the outside.

The end structure of the vehicle further includes a substantially rectangular frame frame that supports heat-dissipating parts in the central region in the vehicle width direction at the front of the vehicle, and the expansion portion is a vehicle body between the left and right vertical frame portions of the frame frame. It may be arranged so as to cover the outer region in the front-rear direction.

In this case, since the expansion portion of the bumper beam covers the outside of the heat radiating component in the front-rear direction of the vehicle body, the heat radiating component can be protected by the expansion portion.

Each of the left and right side frame members includes a first frame extending forward or rearward from the vehicle interior region, and a second frame extending forward or rearward from the vehicle width direction outer region with respect to the vehicle interior. May extend in the vehicle width direction to the left and right outer positions of the second frame in the front-rear direction of the vehicle body.

In this case, since the expansion portion having a wide vertical overhang extends to the outer position in the vehicle body front-rear direction of the outer second frame, the impact load is applied by the expansion portion when other objects move relative to each other in the proximity direction. It can be received stably. In particular, when another object comes into contact with the outside of the center in the vehicle width direction, the impact load is stably received by a wide area of the expansion portion and supported by the first frame and the second frame outside the vehicle width direction. be able to.

The expansion portion has a base portion coupled to an outer portion of the beam main body portion in the front-rear direction of the vehicle body, and an extension portion extending upward and downward from the base portion in at least one of the above and lower directions. The beam main body portion and the extension portion support member for connecting the extension portion are further provided, and the extension portion support member has a bonding flange joined to the inner surface surface of the extension portion in the front-rear direction of the vehicle body. Is also good.

In this case, the joint flange of the extension support member supports the extension of the bumper beam extension from the back side (inside in the front-rear direction of the vehicle body), so that the impact load from the front-rear direction of the vehicle is applied. At the time of input, the tilt of the extension portion can be regulated by the joint flange. Therefore, the impact load input from the front-rear direction of the vehicle body can be efficiently received by the expansion portion.

The extension portion includes an upward extension portion extending upward from the base portion and a downward extension portion extending downward from the base portion, and the extension portion support member joined to the upward extension portion. The extension support member joined to the downward extension may be composed of parts having substantially the same shape.

In this case, the same component can be shared between the extension portion support member joined to the upper extension portion and the extension portion support member joined to the lower extension portion. Therefore, by adopting this configuration, the production efficiency of parts can be improved. Further, in the case of the above configuration, the upper extension support member that supports the upper extension portion and the lower extension support member that supports the lower extension portion are arranged symmetrically in the vertical direction. Therefore, when an impact load is input to the expansion portion from the front-rear direction of the vehicle body, the impact load can be stably received by the cooperation of the upper and lower extension portion support members.

The extension portion includes an upward extension portion extending upward from the base portion and a downward extension portion extending downward from the base portion, and the extension portion support member joined to the upward extension portion. The extension support member joined to the downward extension is connected to each other by a connecting plate inside the beam main body in the front-rear direction of the vehicle body, and is substantially along the connection plate in the vertical direction. Reinforcing beads may be formed.

In this case, the vertical rigidity of the connecting plate is increased by the reinforcing bead. Therefore, the collapse of the upward extending portion and the downward extending portion can be reliably regulated by the reinforcing bead.

The end structure of the vehicle body of another embodiment of the present application includes left and right side frame members extending substantially along the vehicle body front-rear direction and left and right side frame members extending substantially along the vehicle width direction in the front or rear portion of the vehicle body. A bumper beam supported across the side frame member is provided, and the bumper beam is attached to a beam main body portion coupled to the left and right side frame members and the beam main body portion. It is characterized by having an outer surface of the portion in the front-rear direction of the vehicle body and a beam protection member covering the upper and lower surfaces of the beam main body portion.

With the above configuration, when an external object moves relatively close to the outside of the vehicle body in the front-rear direction, the beam protection member covering the outer surface and the upper and lower surfaces of the beam body in the front-rear direction of the vehicle body applies a load from the external object. It will be easier to receive. Since the beam protection member has a wider vertical width than the beam main body, the load can be efficiently received in a wide area and the load is concentrated locally as compared with the case where the load is received only by the beam main body. Can be prevented. Further, in the above configuration, the impact load input to the beam protection member can be transmitted to the left and right side frame members via the beam main body portion, so that the member located on the outside in the front-rear direction of the vehicle interior can be used. It is possible to suppress the displacement toward the passenger compartment.

The end structure of the vehicle body of the present invention is longer in the vertical direction than the beam main body portion in the beam main body portion in which the bumper beam is coupled to the left and right side frame members and at least in the vehicle width direction central region of the beam main body portion. It has an extension and an extension. Therefore, in the end structure of the vehicle body of the present invention, when the impact load is input from the vehicle body front-rear direction, the expansion portion efficiently receives the impact load input from the vehicle body front-rear direction while avoiding local load concentration. be able to.

Further, as shown in FIG. 2, the expansion portion 10 is provided with a stepped notch portion 14 at the outer end portion of the downward extension portion 10l in the vehicle width direction. Therefore, the width of the downward extending portion 10l of the expansion portion 10 in the vehicle width direction is narrower than the width of the upward extending portion 10u in the vehicle width direction. A detector 15 such as a radar or a sensor is arranged on the back side of the left and right notches 14 of the expansion portion 10.
The notch portion 14 may be provided only at the left and right end portions of the downward extending portion 10l. Further, the notch portion 14 can be provided at the outer end portion of the upward extending portion 10u in the vehicle width direction.

As described above, in the vehicle end structure of the present embodiment, the beam main body 9 in which the bumper beam 7 is coupled to the left and right front side frames 2 and the lower member 3 and the central region of the beam main body 9 in the vehicle width direction are formed. In the beam main body portion 9, it has an expansion portion 10 extending in the vertical direction longer than the beam main body portion 9. Therefore, when another vehicle or the like moves relatively close to the vehicle from the front of the vehicle, the expansion portion 10 having a wide vertical width is likely to receive a load from the other vehicle or the like. Since the expansion portion 10 has a wider vertical width than the beam main body portion 9, the load can be efficiently received in a wide area as compared with the case where the load is received only by the beam main body portion 9. Further, in the end structure of the vehicle 1 of the present embodiment, since the load can be received in a wide area of the expansion portion 10, it is possible to prevent the load from being concentrated locally on the bumper beam 7. Therefore, when the end structure of the present embodiment is adopted, the impact load input from the front of the vehicle body is efficiently applied by the expansion unit 10 while avoiding local load concentration when the impact load is input from the front of the vehicle body. I can take it.

Further, in the end structure of the vehicle 1 of the present embodiment, the impact load input to the expansion portion 10 can be transmitted to the left and right front side frames 2 and the lower member 3 via the beam main body portion 9, so that the vehicle can be used. It is possible to prevent the member located in front of the chamber from being displaced toward the passenger compartment.

Further, in the end structure of the vehicle 1 of the present embodiment, the expansion portion 10 is composed of the beam main body portion 9 and a separate component, and the expansion portion 10 which is a separate component is coupled to the beam main body portion 9. .. Therefore, the parts can be shared between the bumper beam having no expansion portion 10 and the bumper beam 7 having the expansion portion 10. Therefore, when the configuration of the present embodiment is adopted, the production efficiency of parts can be improved.

Further, in the end structure of the vehicle 1 of the present embodiment, a notch 14 is provided at the end of the downward extending portion 10l of the expansion portion 10 in the vehicle width direction, and a radar or a radar is provided on the back side of the notch 14. A detector 15 such as a sensor is installed. Therefore, even if the expansion portion 10 having a wide vertical width of the bumper beam 7 is arranged in the central region of the front portion of the vehicle body, the detector 15 can be installed without any inconvenience. Further, by arranging the detector 15 on the rear side of the vehicle body with respect to the expansion portion, the detector 15 can be protected against the load input from the front of the vehicle body.

Further, in the end structure of the vehicle 1 of the present embodiment, the expansion portion 10 of the bumper beam 7 is arranged so as to cover the front region between the left and right vertical frame portions 8a of the frame frame 8. Therefore, the expansion unit 10 can protect heat dissipation parts such as an outdoor heat exchanger and a fan against an impact load input from the front of the vehicle body.

Further, in the end structure of the vehicle 1 of the present embodiment, the expansion portion 10 has a base portion 10b, an upward extension portion 10u, and a downward extension portion 10l, and the support plate 11u, which is connected to the beam main body portion 9. The joining flanges 11uf and 11lf of 11l are joined to the back surfaces of the upward extending portion 10u and the downward extending portion 10l. In this case, since the joint flanges 11uf and 11lf of the support plates 11u and 11l can stably support the back surfaces of the upward extending portion 10u and the downward extending portion 10l on the expansion portion 10, the back surface of the support plates 11u and 11l can be stably supported from the front of the vehicle. When the impact load is input, it is possible to regulate the tilting of the upward extending portion 10u and the downward extending portion 10l. Therefore, when the end structure of the vehicle 1 of the present embodiment is adopted, the impact load input from the front of the vehicle body can be more efficiently received by the expansion unit 10.

In addition, in the present embodiment, since the upper and lower support plates 11u and 11l that support the back surfaces of the upper extension portion 10u and the lower extension portion 10l are composed of parts having substantially the same shape, the upper and lower support plates 11u , 11l can use common parts. Therefore, when this configuration is adopted, the production efficiency of parts can be improved.
Further, in the structure of the present embodiment, since the upper and lower support plates 11u and 11l are arranged symmetrically in the vertical direction, when an impact load is input to the expansion portion 10 from the front of the vehicle body, the upper and lower support plates 11u and 11l are arranged. The impact load can be stably received by the cooperation of.

Further, in the end structure of the vehicle 1 of the present embodiment, the rear end edges of the upper and lower support plates 11u and 11l are connected to each other by the connecting plate 12 on the rear side of the beam main body portion 9 in the vertical direction. A plurality of reinforcing beads 13 extending substantially along are provided on the connecting plate 12. Therefore, in the end structure of the vehicle 1 of the present embodiment, the connecting plate 12 whose rigidity in the vertical direction is enhanced by the reinforcing bead 13 regulates the tilting of the upward extending portion 10u and the downward extending portion 10l of the expansion portion 10. can do.

The end structure of the vehicle shown in FIG. 7 has almost the same basic configuration as that of the above embodiment. The expansion portion 110 of the bumper beam 107 extends outward in the vehicle width direction to a range beyond the front end portions of the left and right lower members 3.

In the end structure of the vehicle 1 of the present embodiment, the expansion portion 110 having a wide vertical overhang extends to a range exceeding the front end positions of the lower members 3 on the left and right outer sides, so that an impact input from the front of the vehicle body is received. The load can be received more stably by the expansion unit 110. In particular, when another vehicle or the like comes into contact with a position that is biased outward from the center in the vehicle width direction, the impact load is stably received by a wide area of the expansion portion 110, and the front side frame 2 and the lower member on the outside in the vehicle width direction are received. Can be supported by 3.
