Summary of the invention
Problems to be solved by the invention
In a conventional end portion structure of a vehicle, a bumper impact beam that receives a load from a vehicle body front-rear direction is formed to have a substantially constant vertical width. Therefore, when an external object such as another vehicle moves relatively in the approaching direction, the region capable of stably receiving the impact load is limited, and local load concentration is likely to occur at the load input point or the like from the external object.
An object to be solved is to provide a vehicle end portion structure capable of avoiding local load concentration and efficiently receiving an impact load input from a vehicle body front-rear direction.
Means for solving the problems
An end portion structure of a vehicle body according to an aspect of the present application is characterized by including: left and right side frame members extending substantially in the front-rear direction of the vehicle body at the front or rear of the vehicle body; and a bumper impact beam extending substantially in the vehicle width direction and supported across the left and right side frame members, wherein the bumper impact beam includes: an impact beam main body portion coupled to the left and right side frame members; and an expanding portion that extends longer in the vertical direction than the impact beam main body portion at least in a vehicle width direction central region of the impact beam main body portion.
With the above configuration, when an external object moves relatively close to the vehicle body from the outer side in the front-rear direction, the load is easily received from the external object by the vertically wide extension portion. Since the expanded portion has a wider vertical width than the impact beam main body portion, the load can be efficiently received in a larger area than when the load is received only by the impact beam main body portion, and the load can be prevented from being locally concentrated. In the above-described structure, the impact load input to the expansion portion can be transmitted to the left and right side frame members via the impact beam main body portion, and therefore, the displacement of the member located on the outer side in the front-rear direction of the vehicle interior in the vehicle interior direction can be suppressed.
The expansion portion may be formed of a separate member from the impact beam main body portion, and may be coupled to the impact beam main body portion.
In this case, since the impact beam main body portion and the expanded portion are formed of separate members, the members can be shared between the bumper impact beam having no expanded portion and the bumper impact beam having an expanded portion. Therefore, the production efficiency of the component can be improved by adopting the structure.
The expanding portion has an upper projecting portion extending upward from the impact beam main body portion and a lower projecting portion extending downward from the impact beam main body portion, and a cutout portion is provided at an outer end portion in the vehicle width direction of either one of the lower projecting portion and the upper projecting portion.
In this case, the sensor, the radar, or the like can be disposed in the notch portion provided in either one of the upper protruding portion and the lower protruding portion. Further, by disposing the sensor, the radar, and the like at a position further toward the inner side in the vehicle body longitudinal direction than the extension portion, the sensor, the radar, and the like can be protected by the extension portion against an input load from the outside.
The end portion structure of the vehicle body may further include a substantially rectangular frame-shaped frame that supports the heat radiating member in a vehicle width direction central region of the vehicle front portion, and the extension portion may be disposed so as to cover an outer region in the vehicle body front-rear direction between the left and right vertical frame portions of the frame-shaped frame.
In this case, since the extension portion of the bumper impact beam covers the outer side of the heat dissipation member in the vehicle body longitudinal direction, the heat dissipation member can be protected by the extension portion.
Each of the left and right side frame members may include: a first frame extending forward or rearward from the vehicle cabin region; and a second frame extending forward or rearward from a region outside the vehicle width direction with respect to the vehicle interior, wherein the expanding portion extends in the vehicle width direction to a position outside the vehicle body longitudinal direction of the left and right second frames.
In this case, since the extension portion having a wide vertical extension width extends to a position outside the second frame in the vehicle longitudinal direction, the extension portion can stably receive the impact load when another object moves relatively in the approaching direction. In particular, when another object abuts against a position outside the center in the vehicle width direction, the impact load can be stably received over a large area by the expanded portion, and the first frame and the second frame on the outer sides in the vehicle width direction can be supported.
The expansion portion may include: a base portion coupled to an outer portion of the impact beam main body portion in the vehicle body longitudinal direction; and a protruding portion that extends at least one of upward and downward from the base portion, wherein the bumper impact beam further includes a protruding portion support member that connects the impact beam main body portion and the protruding portion, and the protruding portion support member has a joining flange that is joined to an inner side surface of the protruding portion in the vehicle body longitudinal direction.
In this case, the joining flange of the extension portion supporting member supports the extension portion in the expanded portion of the bumper impact beam from the back surface side (the inner side in the vehicle body longitudinal direction), and therefore, when an impact load is input from the vehicle longitudinal direction, the falling of the extension portion can be restricted by the joining flange. Therefore, the impact load input from the vehicle body front-rear direction can be efficiently blocked by the expanded portion.
The protruding portion may include an upper protruding portion extending upward from the base portion and a lower protruding portion extending downward from the base portion, and the protruding portion support member joined to the upper protruding portion and the protruding portion support member joined to the lower protruding portion may be formed of members having substantially the same shape.
In this case, the same components can be shared in the extension supporting member engaged with the upper extension and the extension supporting member engaged with the lower extension. Therefore, the production efficiency of the component can be improved by adopting this structure. In the above configuration, the upper projecting portion support member that supports the upper projecting portion and the lower projecting portion support member that supports the lower projecting portion are disposed vertically symmetrically, so that when an impact load is input to the extension portion from the vehicle body longitudinal direction, the impact load can be stably received by cooperation of the upper and lower projecting portion support members.
The projecting portion may include an upper projecting portion extending upward from the base portion and a lower projecting portion extending downward from the base portion, the projecting portion support member joined to the upper projecting portion and the projecting portion support member joined to the lower projecting portion may be joined to each other by a joining plate on an inner side in the vehicle body longitudinal direction of the impact beam main body portion, and a reinforcing rib extending substantially in the vertical direction may be formed on the joining plate.
In this case, the vertical rigidity of the connecting plate can be improved by the ribs. Therefore, the rib can reliably restrict the lying of the upper and lower projecting portions.
Another aspect of the present application provides a vehicle body end portion structure including: left and right side frame members extending substantially in the front-rear direction of the vehicle body at the front or rear of the vehicle body; and a bumper impact beam extending substantially in the vehicle width direction and supported across the left and right side frame members, wherein the bumper impact beam includes: an impact beam main body portion coupled to the left and right side frame members; and an impact beam protection member that is attached to the impact beam main body and covers the outer side surface of the impact beam main body in the vehicle body longitudinal direction and the upper and lower surfaces of the impact beam main body.
With the above-described structure, when an external object moves relatively close to the vehicle body from the outer side in the front-rear direction, the impact beam protection member that covers the outer side surface and the upper and lower surfaces of the impact beam main body in the front-rear direction of the vehicle body is likely to receive a load from the external object. Since the impact beam protection member has a wider vertical width than the impact beam main body, the impact beam protection member can efficiently receive a load over a large area and prevent the load from being locally concentrated, as compared with the case where the load is received only by the impact beam main body. In the above-described structure, the impact load input to the impact beam protecting member can be transmitted to the left and right side frame members via the impact beam main body portion, and therefore, the displacement of the member located on the outer side in the front-rear direction of the vehicle interior in the vehicle interior direction can be suppressed.
Effects of the invention
In the end portion structure of a vehicle body according to the present invention, a bumper impact beam includes: an impact beam main body portion coupled to the left and right side frame members; and an expanding portion that extends longer than the impact beam main body portion in the vertical direction at least in a vehicle width direction central region of the impact beam main body portion. Therefore, in the end portion structure of the vehicle body according to the present invention, when an impact load is input from the vehicle body longitudinal direction, the impact load input from the vehicle body longitudinal direction can be efficiently received by the expanded portion while avoiding local load concentration.

The vehicle 1 of the present embodiment is provided with a pair of left and right front side frames 2 (first frames) extending substantially in the vehicle body front-rear direction at the front portion of the vehicle body. Further, a lower beam 3 (second frame) extending from the vicinity of the upper suspension support portion to be bent downward toward the front side is provided on the vehicle width direction outer side of the left and right front side frames 2.
The front side frame 2 (first frame) extends forward of the vehicle body from the cabin region, and the lower beam 3 (second frame) extends forward of the vehicle body from a position further toward the vehicle width direction outer region than the cabin. In the present embodiment, the left and right front side frames 2 and the lower member 3 constitute side frame members of the vehicle front portion.
Further, a frame-shaped frame 8 for supporting heat dissipation members such as an outdoor heat exchanger and a fan is attached to the front end side of the left and right front side frames 2. The frame-like frame 8 is formed in a substantially rectangular shape in front view. The frame 8 is disposed in a vehicle width direction center region of the vehicle body front portion. The bumper impact beam 7 is disposed across the front of the frame-shaped frame 8 in the vehicle width direction.
The frame-shaped frame 8 has: left and right vertical frame portions 8 a; an upper frame portion 8b connecting upper end portions of the left and right vertical frame portions 8a to each other; and a lower frame portion 8c that connects lower end portions of the left and right vertical frame portions 8a to each other. The heat radiating member such as an outdoor heat exchanger or a fan is disposed inside or behind the opening of the frame-shaped frame 8.
Fig. 4 is a cross-sectional view of the bumper impact beam 7 taken along the line IV-IV of fig. 2, and fig. 5 is a view of the right-side portion of the bumper impact beam 7 viewed from obliquely above and rearward. Fig. 6 is a view of a central region of the bumper impact beam 7 in the vehicle width direction as viewed from the back side (rear side).
The bumper impact beam 7 has: an impact beam main body 9 having left and right side portions coupled to the left and right front side frames 2 and the lower beam 3 (left and right side frame members of the vehicle body) via the first extension portion 5 and the second extension portion 6; and an expansion portion 10 integrally attached to a central region of the impact beam main body portion 9 in the vehicle width direction. The expanded portion 10 is formed of a hard plate material such as a high tensile steel plate.
The impact beam main body portion 9 is formed in a substantially hat-shaped cross-sectional shape that opens to the vehicle body rear side, and the cross section thereof extends in the entire vehicle width direction. The center region of the impact beam main body portion 9 in the vehicle width direction is formed to have a substantially constant vertical width. The expansion portion 10 extends longer in the vertical direction than the impact beam main body portion 9.
As shown in fig. 4, the expanding portion 10 includes: a base portion 10b coupled to a front surface (an outer portion in the vehicle body longitudinal direction) of the impact beam main body portion 9; an upper extension portion 10u extending upward while being inclined toward the vehicle body rear side from the upper end of the base portion 10 b; and a downward extending portion 10l extending downward while being inclined toward the vehicle body rear side from the lower end of the base portion 10 b. The base portion 10b covers the front surface (outer side surface in the vehicle body longitudinal direction) of the impact beam main body portion 9, and the upper protruding portion 10u and the lower protruding portion 10l cover the upper surface and the lower surface of the impact beam main body portion 9, respectively. The expansion portion 10 constitutes an impact beam protection member that covers the outer side surface and the upper and lower surfaces of the impact beam main body portion 9 in the vehicle body longitudinal direction.
As shown in fig. 4, the center region of the impact beam main body portion 9 in the vehicle width direction has a pair of upper and lower flange portions 9 f. The flange portions 9f are formed by bending upward and downward from the vehicle body rear side end portions of the upper and lower horizontal walls of the impact beam main body portion 9. The upper flange portion 9f of the impact beam body 9 is connected to the rear surface of the upper extension 10u of the expansion portion 10 via a support plate 11u having a substantially Z-shaped cross section. The lower flange portion 9f of the impact beam body portion 9 is connected to the rear surface of the lower extension 10l of the expansion portion 10 via a support plate 11l having a substantially Z-shaped cross section. The support plates 11u and 11l constitute extension portion support members that connect the impact beam main body portion 9 and the respective extension portions (the upper extension portion 10u and the lower extension portion 10 l).
The upper support plate 11u has a joining flange 11uf extending by being bent upward in the vicinity of the upper protruding portion 10u, and this joining flange 11uf is joined by welding or the like to the rear surface of the upper end side of the upper protruding portion 10u of the expanding portion 10. Similarly, the lower support plate 11l has a joining flange 11lf bent and extending downward in the vicinity of the lower extension portion 10l, and the joining flange 11lf is joined to the rear surface of the lower end side of the lower extension portion 10l of the extension portion 10 by welding or the like. The upper support plate 11u and the lower support plate 11l are formed of members having substantially the same shape. The upper support plate 11u and the lower support plate 11l may be turned upside down and used as a common member.
The rear-side end edges of the upper support plate 11u and the lower support plate 11l are connected to each other by a horizontally long rectangular connecting plate 12 on the rear side of the impact beam body 9. The upper support plate 11u, the upper edge portion of the connecting plate 12, and the upper flange portion 9f of the impact beam body 9 may be welded and fixed in a state where three are overlapped. Similarly, the lower support plate 11l, the lower edge portion of the connecting plate 12, and the upper flange portion 9f of the impact beam body 9 may be welded and fixed in a state where three are superposed.
As shown in fig. 5 and 6, the web 12 is formed with a bead 13 extending substantially in the vertical direction. The reinforcing ribs 13 are provided in plural and separated in the longitudinal direction of the coupling plate 12.
As shown in fig. 2, the extension portion 10 of the bumper impact beam 7 is disposed so as to cover a front region (a region outside in the vehicle body longitudinal direction) between the left and right vertical frame portions 8a of the frame-shaped frame 8. Specifically, the left and right end portions of the expanding portion 10 are disposed so as to partially overlap the left and right corresponding vertical frame portions a when viewed from the front of the vehicle.
As shown in fig. 2, the expanded portion 10 is provided with a stepped cut portion 14 at the vehicle width direction outer side end portion of the lower protruding portion 10 l. Therefore, the width of the lower extension portion 10l of the expanded portion 10 in the vehicle width direction is narrower than the width of the upper extension portion 10u in the vehicle width direction. Detectors 15 such as radars and sensors are disposed on the back side of the left and right notches 14 of the expanding portion 10.
The notch 14 may be provided only at one of the left and right ends of the lower protruding portion 10 l. The cutout portion 14 may be provided at the vehicle width direction outer side end portion of the upper extending portion 10 u.
As described above, in the vehicle end portion structure of the present embodiment, the bumper impact beam 7 includes: an impact beam main body 9 coupled to the left and right front side frames 2 and the lower beam 3; and an expanding portion 10 that extends longer in the vehicle width direction central region of the impact beam main body portion 9 than the impact beam main body portion 9 in the up-down direction. Therefore, when another vehicle or the like moves relatively close to the vehicle from the front, the load is easily received from the other vehicle or the like by the vertically wide expanding portion 10. Since the expanded portion 10 is wider in vertical width than the impact beam main body portion 9, it can efficiently receive a load over a large area as compared with a case where a load is received only by the impact beam main body portion 9. Further, in the end portion structure of the vehicle 1 of the present embodiment, since the load can be received in a large area by the expanded portion 10, it is possible to prevent the load from concentrating on a part of the bumper impact beam 7. Therefore, when the end portion structure of the present embodiment is employed, the impact load input from the front of the vehicle body can be efficiently received by the enlarged portion 10 while avoiding local load concentration at the time of input of the impact load from the front of the vehicle body.
In the end portion structure of the vehicle 1 according to the present embodiment, since the impact load input to the expansion portion 10 can be transmitted to the left and right front side frames 2 and the lower beam 3 via the impact beam main body portion 9, it is possible to suppress displacement of the member located in front of the vehicle interior in the vehicle interior direction.
In the end portion structure of the vehicle 1 according to the present embodiment, the expansion portion 10 is formed of a separate member from the impact beam main body portion 9, and the expansion portion 10 as the separate member is coupled to the impact beam main body portion 9. Therefore, the bumper impact beam without the expanded portion 10 and the bumper impact beam 7 with the expanded portion 10 can share the members. Therefore, when the structure of the present embodiment is employed, the production efficiency of the component can be improved.
In the end portion structure of the vehicle 1 of the present embodiment, a cutout portion 14 is provided at an end portion in the vehicle width direction of the lower extension portion 10l of the expanded portion 10, and a detector 15 such as a radar or a sensor is provided on a back side of the cutout portion 14. Therefore, even if the expanded portion 10 of the bumper impact beam 7, which is wide in the vertical width, is disposed in the central region of the front portion of the vehicle body, the detector 15 can be provided without discomfort. Further, by disposing the detector 15 on the vehicle rear side of the expanded portion, the detector 15 can be protected against load input from the vehicle front.
In the end portion structure of the vehicle 1 according to the present embodiment, the extension portion 10 of the bumper impact beam 7 is disposed so as to cover the front region between the left and right vertical frame portions 8a of the frame-shaped frame 8. Therefore, the extension portion 10 can protect the heat dissipation components such as the outdoor heat exchanger and the fan against the impact load input from the front of the vehicle body.
In the end portion structure of the vehicle 1 according to the present embodiment, the expanded portion 10 includes the base portion 10b, the upper projecting portion 10u, and the lower projecting portion 10l, and the engaging flanges 11uf and 11lf of the support plates 11u and 11l coupled to the impact beam main body portion 9 are engaged with the respective rear surfaces of the upper projecting portion 10u and the lower projecting portion 10 l. In this case, since the joint flanges 11uf and 11lf of the support plates 11u and 11l can stably support the respective rear surfaces of the upper extension portion 10u and the lower extension portion 10l in the extension portion 10, the upper extension portion 10u and the lower extension portion 10l can be restrained from falling down when an impact load is input from the front of the vehicle. Therefore, when the end portion structure of the vehicle 1 according to the present embodiment is adopted, the impact load input from the front of the vehicle body can be more efficiently received by the enlarged portion 10.
In the present embodiment, the upper and lower support plates 11u and 11l that support the rear surfaces of the upper extension portion 10u and the lower extension portion 10l are formed of members having substantially the same shape, and therefore common members can be used for the upper and lower support plates 11u and 11 l. Therefore, when this structure is adopted, the production efficiency of the component can be improved.
In the configuration of the present embodiment, the upper and lower support plates 11u and 11l are disposed vertically symmetrically, so that when an impact load is input to the extension 10 from the front of the vehicle body, the upper and lower support plates 11u and 11l cooperate with each other to stably receive the impact load.
In the end portion structure of the vehicle 1 according to the present embodiment, the rear end edges of the upper and lower support plates 11u and 11l are coupled to each other by the coupling plate 12 at the rear side of the impact beam body 9, and a plurality of beads 13 extending substantially in the vertical direction are provided in the coupling plate 12. Therefore, in the end portion structure of the vehicle 1 of the present embodiment, the connecting plate 12 having the rigidity in the vertical direction increased by the bead 13 can restrict the falling of the upper extending portion 10u and the lower extending portion 10l of the expanding portion 10.
Fig. 7 is a front view showing a skeleton portion of a front portion of a vehicle 1 according to another embodiment.
The basic structure of the end portion structure of the vehicle shown in fig. 7 is substantially the same as that of the above-described embodiment, but the expanded portion 110 of the bumper impact beam 107 extends outward in the vehicle width direction to a range beyond the front end portions of the left and right lower beams 3.
In the end portion structure of the vehicle 1 of the present embodiment, the expanded portion 110 having a wide vertical extension extends beyond the position of the front end portion of the left and right outer side lower rails 3, so that the impact load input from the front of the vehicle body can be received more stably by the expanded portion 110. In particular, when another vehicle or the like comes into contact with a position that is offset outward from the center in the vehicle width direction, the impact load can be stably received over a large area by the enlarged portion 110, and the front side frame 2 and the underbeam 3 on the outer sides in the vehicle width direction can be supported.
The present invention is not limited to the above-described embodiments, and various design changes may be made without departing from the scope of the invention. For example, in the above-described embodiment, the end portion structure of the vehicle of the present invention is applied to the skeleton portion of the front portion of the vehicle, but the end portion structure of the vehicle of the present invention can be similarly applied to the skeleton portion of the rear portion of the vehicle. The expanded portion of the bumper impact beam may be formed integrally with the impact beam main body portion.
