Summary of the application
Problems to be solved by the application
In the end portion structure of the conventional vehicle, the bumper beam that receives the load from the front-rear direction of the vehicle body is formed to have a substantially constant vertical width. Therefore, when an external object such as another vehicle is relatively moved in the approaching direction, the area capable of stably receiving the impact load is limited, and local load concentration is likely to occur at a load input point or the like of the external object.
The object to be solved is to provide an end structure of a vehicle capable of efficiently receiving an impact load input from the front-rear direction of the vehicle body while avoiding local load concentration.
Means for solving the problems
An end structure of a vehicle body according to an aspect of the present application includes: left and right side frame members extending in a front or rear direction of the vehicle body in a substantially longitudinal direction of the vehicle body; and a bumper beam extending substantially in the vehicle width direction and supported across the left and right side frame members, wherein the bumper beam includes: an impact beam main body portion coupled to the left and right side frame members; and an expansion portion that extends longer than the impact beam main body portion in the up-down direction at least in a vehicle width direction central region of the impact beam main body portion.
With the above configuration, when the external object is relatively moved close to the vehicle body from the outside in the front-rear direction, the load is easily received from the external object by the expansion portion having a wide vertical width. The expansion portion has a width greater than the vertical width of the impact beam main body portion, and therefore, can support a load in a large area and efficiently, and can prevent the load from being concentrated locally, as compared with the case where the load is supported only by the impact beam main body portion. In the above-described configuration, since 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, displacement of the member located outside the vehicle interior in the front-rear direction 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 bumper beam main body portion and the expansion portion are formed of separate members, the members can be shared by the bumper beam having no expansion portion and the bumper beam having the expansion portion. Therefore, by adopting the present structure, improvement in the production efficiency of the component can be achieved.
The expansion portion has an upper extension portion extending upward from the impact beam main body portion and a lower extension portion extending downward from the impact beam main body portion, and a notch portion is provided at an end portion of either the lower extension portion or the upper extension portion on an outer side in the vehicle width direction.
In this case, a sensor, radar, or the like can be disposed in the cutout portion provided in either one of the upper protruding portion and the lower protruding portion. Further, by disposing the sensor, the radar, or the like at the inner side in the vehicle body front-rear direction than the expansion portion, the sensor, the radar, or the like can be protected by the expansion portion against an input load from the outside.
The end portion structure of the vehicle body may further include a substantially rectangular frame-like frame that supports the heat radiating member in a vehicle width direction central region of the vehicle front portion, and the expansion portion may be disposed so as to cover an outer region in the vehicle body front-rear direction between left and right longitudinal frame portions of the frame-like frame.
In this case, since the expansion portion of the bumper beam covers the outer side of the heat radiating member in the vehicle body front-rear direction, the heat radiating member can be protected by the expansion portion.
Each of the left and right side frame members may include: a first frame extending forward or backward from the vehicle compartment area; and a second frame extending forward or rearward from a position closer to a vehicle width direction outer region than the vehicle cabin, wherein the expanding portion extends in the vehicle width direction to a vehicle body front-rear direction outer position of the second frame.
In this case, since the expansion portion having a wide extension in the vertical direction extends to the outer position in the vehicle body front-rear direction of the outer second frame, the impact load can be stably received by the expansion portion when the other object moves relatively in the approaching direction. In particular, when another object is in contact with the outer side than the center in the vehicle width direction, the impact load can be stably received over a large area of the expansion portion, and the first frame and the second frame on the outer side in the vehicle width direction can be supported.
The expansion unit may have: a base body portion coupled to an outer portion of the bumper beam body portion in a vehicle body front-rear direction; and a protruding portion that extends from at least one of the base portion upward and downward, wherein the bumper beam further includes a protruding portion support member that connects the bumper beam main body portion and the protruding portion, the protruding portion support member having a joining flange that joins with an inner side surface of the protruding portion in a vehicle body front-rear direction.
In this case, the engagement flange of the extension portion support member supports the extension portion in the expansion portion of the bumper beam from the rear surface side (the inner side in the vehicle body front-rear direction), so that the extension portion can be restrained from lying down by the engagement flange at the time of input of an impact load from the vehicle front-rear direction. Therefore, the impact load input from the front-rear direction of the vehicle body can be efficiently received by the expansion 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 substantially the same shape.
In this case, the same components can be shared in the projection support member engaged with the upper projection and the projection support member engaged with the lower projection. Therefore, by adopting this structure, the production efficiency of the component can be improved. In the case of the above-described structure, since the upper extension supporting member supporting the upper extension and the lower extension supporting member supporting the lower extension are arranged vertically symmetrically, 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 cooperation of the upper and lower extension supporting members.
The extension portion may include an upper extension portion extending upward from the base portion and a lower extension portion extending downward from the base portion, the extension portion support member joined to the upper extension portion and the extension portion support member joined to the lower extension portion may be connected to each other at an inner side of the bumper beam body portion in the vehicle body front-rear direction by a connecting plate, and a reinforcing rib substantially along the vertical direction may be formed on the connecting plate.
In this case, the rigidity of the connecting plate in the up-down direction can be improved by the reinforcing ribs. Therefore, the rib can reliably restrict the upper and lower protruding portions from lying down.
Another aspect of the present application is an end structure of a vehicle body, comprising: left and right side frame members extending in a front or rear direction of the vehicle body in a substantially longitudinal direction of the vehicle body; and a bumper beam extending substantially in the vehicle width direction and supported across the left and right side frame members, wherein the bumper beam includes: an impact beam main body portion coupled to the left and right side frame members; and an impact beam protection member attached to the impact beam body portion and covering an outer side surface of the impact beam body portion in a vehicle body front-rear direction and upper and lower surfaces of the impact beam body portion.
With the above-described structure, when an external object is relatively moved close to the vehicle body from the outside in the vehicle body front-rear direction, the impact beam protection member covering the outer side surface and the upper and lower surfaces of the impact beam main body portion in the vehicle body front-rear direction easily receives a load from the external object. Since the bumper beam protection member has a width greater than the width of the bumper beam body in the vertical direction, the bumper beam protection member can efficiently support a load over a large area, and can prevent the load from being locally concentrated, compared to the case where the load is supported only by the bumper beam body. In the above-described configuration, since the impact load input to the impact beam protection member can be transmitted to the left and right side frame members via the impact beam main body portion, displacement of the member located outside the vehicle interior in the front-rear direction in the vehicle interior direction can be suppressed.
Effects of the application
In an end structure of a vehicle body according to the present application, a bumper beam includes: an impact beam main body portion coupled to the left and right side frame members; and an expansion portion that extends longer than the impact beam main body portion in the up-down 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 application, when the impact load is input from the front-rear direction of the vehicle body, the impact load input from the front-rear direction of the vehicle body can be efficiently received by the expansion portion while avoiding localized 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 the front side and extending downward is provided on the vehicle width direction outer sides of the left and right front side frames 2.
The front side frame 2 (first frame) extends forward of the vehicle body from the vehicle cabin region, and the underbeam 3 (second frame) extends forward of the vehicle body from a position outside the vehicle cabin in the vehicle width direction. In the present embodiment, the left and right front side frames 2 and the underbeam 3 constitute side frame members of the front portion of the vehicle body.
A base plate 4 is attached to the front end portions of the front side frames 2 and the lower beams 3 on the same side in the right and left direction so as to vertically stand toward the front of the vehicle. A substantially cylindrical first extension 5 is attached to the front surface of the base plate 4 at an extension position of the front side frame 2. A substantially cylindrical second extension portion 6 is attached to a front surface of the base plate 4 at a position overlapping a front end portion of the lower beam 3 in the front-rear direction. The front end portions of the first extension portion 5 and the second extension portion 6 are coupled to the rear surfaces of the side portions of the bumper beam 7 extending substantially in the vehicle width direction. Therefore, the bumper beam 7 is supported across the side frame members (the front side frame 2 and the lower beam 3) on the left and right sides of the vehicle body. A resin-made bumper face, not shown, is disposed on the front surface side of the bumper beam 7.
A frame-like frame 8 for supporting heat radiation members such as an outdoor heat exchanger and a fan is attached to the front end sides of the left and right front side frames 2.

The bumper beam 7 is disposed across the front of the frame-like frame 8 in the vehicle width direction.
The frame-like frame 8 has: left and right vertical frame portions 8a; 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 connecting lower end portions of the left and right vertical frame portions 8a to each other. Heat radiating members such as an outdoor heat exchanger and a fan are disposed inside or behind the opening of the frame-like frame 8.
Fig. 4 is a cross-sectional view of the bumper beam 7 taken along the line IV-IV of fig. 2, and fig. 5 is a view of a right-side portion of the bumper beam 7 viewed obliquely from above and behind. Fig. 6 is a view of the center region of the bumper beam 7 in the vehicle width direction, as viewed from the back side (rear side).
The bumper beam 7 includes: a bumper beam main body 9 in which the left and right side portions are coupled to the left and right corresponding front side frames 2 and the underbeam 3 (left and right side frame members of the vehicle body) via first extension portions 5 and second extension portions 6; and an expansion portion 10 integrally attached to a central region of the bumper beam body portion 9 in the vehicle width direction. The expansion portion 10 is formed of a hard plate material such as a high-tensile steel plate, for example.
The impact beam body 9 is formed in a substantially hat-shaped cross-section that opens toward the rear side of the vehicle body, and its cross-section extends in the vehicle width direction. The center region of the impact beam body 9 in the vehicle width direction is formed to have a substantially constant vertical width. The expansion portion 10 extends longer than the impact beam main body portion 9 in the up-down direction.
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 front-rear 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 10b; and a lower extension portion 10l extending downward while being inclined from the lower end of the base portion 10b toward the vehicle body rear side. The base portion 10b covers the front surface (outer side surface in the vehicle body front-rear 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 front-rear direction.
As shown in fig. 4, the center region of the impact beam body 9 in the vehicle width direction has a pair of upper and lower flange portions 9f. The flange portion 9f is formed by bending upward and downward from the end portion of each of the upper and lower horizontal walls of the impact beam main body portion 9 on the vehicle body rear side. The flange 9f on the upper side of the impact beam body 9 is connected to the rear surface of the upper extension 10u of the expansion section 10 via a support plate 11u having a substantially Z-shaped cross section. The flange portion 9f on the lower side of the impact beam body portion 9 is connected to the rear surface of the lower extension portion 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 support members that connect the impact beam main body 9 to the respective extensions (upper extension 10u and lower extension 10 l).
The upper support plate 11u has a joining flange 11uf extending by bending upward in the vicinity of the upper extension 10u, and the joining flange 11uf is joined to the rear surface of the upper end of the upper extension 10u of the expansion 10 by welding or the like. Similarly, the lower support plate 11l has a joining flange 11lf extending by bending 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 expansion portion 10 by welding or the like. The upper support plate 11u and the lower support plate 11l are formed of substantially identical members. The upper support plate 11u and the lower support plate 11l can be turned upside down to use a common member.
The rear end edges of the upper support plate 11u and the lower support plate 11l are connected to each other at the rear side of the impact beam body 9 by a laterally long rectangular connecting plate 12. The upper support plate 11u, the upper edge portion of the connecting plate 12, and the upper flange portion 9f of the impact beam main body 9 may be welded and fixed in a three-piece stacked state. 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 of three overlapping.
As shown in fig. 5 and 6, the web 12 is formed with a reinforcing rib 13 extending substantially in the vertical direction. The reinforcing ribs 13 are provided in plural in a separated manner in the longitudinal direction of the connecting plate 12.
As shown in fig. 2, the expansion portion 10 of the bumper beam 7 is disposed so as to cover a front region (an outer region in the vehicle body longitudinal direction) between the left and right vertical frame portions 8a of the frame-like frame 8. Specifically, the left and right end portions of the expansion portion 10 are arranged 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 expansion portion 10 has a stepped notch 14 at an outer end portion of the lower extension portion 10l in the vehicle width direction. Therefore, the width of the lower extension portion 10l of the expansion portion 10 in the vehicle width direction is smaller than the width of the upper extension portion 10u in the vehicle width direction. A detector 15 such as a radar or a sensor is disposed on the back side of the left and right cutout portions 14 of the expansion portion 10.
The notch 14 may be provided only at one of the left and right ends of the lower extension 10l. The notch 14 may be provided at an end portion of the upper extension portion 10u on the outer side in the vehicle width direction.
As described above, in the vehicle end portion structure of the present embodiment, the bumper beam 7 includes: an impact beam main body 9 coupled to the left and right front frames 2 and the lower beam 3; and an expansion portion 10 that extends longer in the up-down direction than the impact beam main body portion 9 in the vehicle width direction center region of the impact beam main body portion 9. Therefore, when another vehicle or the like is relatively moved from the front of the vehicle, the load is easily received from the other vehicle or the like by the expanding portion 10 having a wide vertical width. Since the expansion portion 10 has a larger vertical width than the impact beam main body portion 9, the load can be efficiently received over a large area than when the load is received only by the impact beam main body portion 9. In the end portion structure of the vehicle 1 according to the present embodiment, the load can be received over a large area of the expansion portion 10, and therefore, the load can be prevented from being concentrated on a part of the bumper beam 7. Therefore, in the case of the end structure of the present embodiment, local load concentration can be avoided when the impact load is input from the front of the vehicle body, and the impact load input from the front of the vehicle body can be efficiently received by the expansion portion 10.
In the end 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, displacement of the member located in front of the vehicle interior in the vehicle interior direction can be suppressed.
In the end structure of the vehicle 1 according to the present embodiment, the expansion portion 10 is formed of a separate member that is separate from the impact beam main body portion 9, and the expansion portion 10, which is a separate member, is coupled to the impact beam main body portion 9. Therefore, the member can be shared by the bumper beam having no expansion portion 10 and the bumper beam 7 having the expansion portion 10. Therefore, when the structure of the present embodiment is adopted, improvement in the production efficiency of the component can be achieved.
In the end structure of the vehicle 1 of the present embodiment, a notch 14 is provided at the vehicle width direction end of the lower extension portion 10l of the expansion portion 10, and a detector 15 such as a radar or a sensor is provided on the back side of the notch 14. Therefore, even if the expansion portion 10 having a wide up-down width of the bumper beam 7 is disposed in the central region of the vehicle body front portion, the detector 15 can be provided without discomfort. Further, by disposing the detector 15 on the vehicle body rear side of the expansion portion, the detector 15 can be protected against load input from the vehicle body front.
In the end structure of the vehicle 1 according to the present embodiment, the expansion portion 10 of the bumper beam 7 is disposed so as to cover the front region between the left and right vertical frame portions 8a of the frame-like frame 8. Therefore, the heat radiation members such as the outdoor heat exchanger and the fan can be protected by the expansion portion 10 against the impact load input from the front of the vehicle body.
In the end structure of the vehicle 1 according to the present embodiment, the expansion portion 10 includes the base portion 10b, the upper protruding portion 10u, and the lower protruding portion 10l, and the joining flanges 11uf, 11lf of the support plates 11u, 11l connected to the impact beam main body portion 9 are joined to the respective rear surfaces of the upper protruding portion 10u and the lower protruding portion 10l. In this case, the joining flanges 11uf, 11lf of the support plates 11u, 11l can stably support the respective rear surfaces of the upper extension portion 10u and the lower extension portion 10l on the expansion portion 10, so that the upper extension portion 10u and the lower extension portion 10l can be restrained from lying down when an impact load from the front of the vehicle is input. Therefore, in the case where the end structure of the vehicle 1 of the present embodiment is employed, the impact load input from the front of the vehicle body can be more efficiently received by the expansion portion 10.
In the present embodiment, the upper and lower support plates 11u, 11l that support the rear surfaces of the upper extension portion 10u and the lower extension portion 10l are formed of substantially identical shaped members, and therefore, a common member can be used for the upper and lower support plates 11u, 11 l. Therefore, in the case of adopting this structure, the production efficiency of the component can be improved.
In the structure of the present embodiment, the upper and lower support plates 11u, 11l are arranged vertically symmetrically, so that when an impact load is input from the vehicle body front direction expansion portion 10, the impact load can be stably received by cooperation of the upper and lower support plates 11u, 11 l.
In the end structure of the vehicle 1 of the present embodiment, the rear end edges of the upper and lower support plates 11u, 11l are connected to each other via the connecting plate 12 on the rear side of the bumper beam main body 9, and a plurality of reinforcing ribs 13 extending substantially in the up-down direction are provided on the connecting plate 12. Therefore, in the end structure of the vehicle 1 according to the present embodiment, the connecting plate 12 having the rigidity in the vertical direction increased by the reinforcing ribs 13 can restrict the upward extending portion 10u and the downward extending portion 10l of the expanding portion 10 from being laid down.
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 vehicle end portion structure shown in fig. 7 is substantially the same as that of the above-described embodiment, but 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 under beams 3.
In the end portion structure of the vehicle 1 of the present embodiment, the expansion portion 110 having a wide extension in the vertical direction extends beyond the range of the front end portion position of the left and right outer side lower beams 3, so that the impact load input from the front of the vehicle body can be more stably received by the expansion portion 110. In particular, when another vehicle or the like is in contact with a position that is offset to the outside from the center in the vehicle width direction, the impact load can be stably received over a large area of the expansion portion 110, and the front side frame 2 and the rocker 3 on the outside in the vehicle width direction can be supported.
The present application is not limited to the above-described embodiments, and various design changes may be made without departing from the spirit and scope of the present application. For example, in the above-described embodiment, the end structure of the vehicle of the present application is applied to the skeleton portion of the front portion of the vehicle, but the end structure of the vehicle of the present application is also applicable to the skeleton portion of the rear portion of the vehicle. In addition, the expansion portion of the bumper beam may be integrally formed with the bumper beam body portion.
