Description

  The present invention relates to a vehicle body front structure in which a crash can is interposed between a bumper beam and a front side frame.

  2. Description of the Related Art Conventionally, a technique is known in which a pair of left and right front side frames extending in the longitudinal direction of a vehicle body are provided at the front of a vehicle body and the impact load is absorbed by the front side frame being crushed when the vehicle collides forward.

  However, a frontal collision of the vehicle may occur in the vehicle body portion on the outer side in the vehicle width direction than the front side frame. Thus, the front collision in which the vehicle body and the collision object overlap with each other with a small width (for example, about 25% of the vehicle width) in the vehicle width direction may be referred to as a small overlap collision.

  When the collision object of this small overlap collision is a pillar-shaped object such as a power pole or a traffic sign pole, the collision object may become such that the pillar-shaped collision object enters between the front side frame and the front wheel. In this case, there is a problem that load transmission efficiency to the front side frame is lowered. In addition, even in the case of a small overlap collision with a non-columnar collision object such as an oncoming vehicle, the load transmission efficiency to the front side frame is greater than when the collision object and the front side frame overlap in the vehicle width direction. Will be inferior. Therefore, in the case of a small overlap collision, there is a problem that the amount of shock absorption due to the deformation of the front side frame is likely to be reduced, and the impact load is easily transmitted to the passenger compartment side.

  For this problem, Patent Document 1 discloses a vehicle body front structure shown in FIG. In the conventional structure shown in FIG. 10, a bifurcated member 150 is provided between the front end of the front side frame 104 and the bumper beam 110 so as to bifurcate and extend forward. The bifurcated member 150 includes a rectilinear member 152 that extends from the front end of the front side frame 104 without inclining forward, and an outer inclined member 154 that extends from the front end of the front side frame 104 toward the front in a direction inclined outward in the vehicle width direction. The rear end portion of the rectilinear member 152 and the rear end portion of the outer inclined member 154 are coupled by bolts. According to this structure, even in the case of a small overlap collision, the impact load received by the outer inclined member 154 is transmitted to the front side frame 104, and the front side frame 104 is effectively deformed to cause an impact. Can be absorbed, and the impact transmitted to the passenger compartment can be mitigated.

JP 2004-066932 A

  By the way, generally, a crash can is interposed between the front end of the front side frame and the bumper beam. In this case, for example, at the time of a low-speed collision of about 15 km / h, the impact load can be absorbed only by the deformation of the crash can without causing damage to the front side frame, and the repair cost can be reduced.

  In this regard, in the conventional structure shown in FIG. 10 described above, if the rectilinear member 152 has a low rigidity such as a crash can, the front side frame 104 is damaged by deformation of the rectilinear member 152 at the time of a low-speed collision. It is considered that it is possible to absorb the impact load without any problem. In this case, the rectilinear member 152 can be regarded as the crush can.

  However, in the structure shown in FIG. 10, not only the rectilinear member 152 but also the outer inclined member 154 is disposed in front of the front side frame 104, so that the impact load at the time of low-speed collision is caused by the deformation of the rectilinear member 152. When absorbed, not only the rectilinear member 152 but also the outer inclined member 154 is damaged, and there is a problem that the repair cost increases accordingly.

  On the other hand, in the conventional structure shown in FIG. 10, if the rectilinear member 152 has such a large rigidity that it cannot function as a crash can, the impact is directly input to the front side frame 104 even during a low-speed collision. As a result, the front side frame 104 is likely to be damaged, which may further increase the cost of repair.

  In general, the bumper beam is provided so that both ends thereof extend to the joint portion with the crash can. However, when the structure including the outer inclined member 154 as shown in FIG. It is necessary to further extend both ends to the joint portion with the outer inclined member 154. Therefore, it is necessary to bend the both ends of the bumper 120 backward in an angular manner so as not to interfere with the both ends of the long bumper beam 110. For example, as shown by the two-dot chain line R in FIG. Cannot bend backwards. Therefore, there is also a problem that receives restrictions on the design of the front part of the vehicle body.

  Therefore, the present invention suppresses the repair cost when the crash can is damaged by a low-speed collision in the vehicle body front structure in which the bumper beam and the front side frame are coupled via the crash can. The objective is to mitigate the impact transmitted to the passenger compartment during a small overlap collision while maintaining good design freedom.

  In order to solve the above problems, the vehicle body front structure according to the present invention is configured as follows.

First, the invention according to claim 1 of the present application is
Bumper beams extending in the vehicle width direction at the front of the vehicle body, and a pair of left and right front side frames extending in the vehicle longitudinal direction and having front ends connected to both ends of the bumper beam via a crash can. A vehicle body front structure,
A first projecting portion projecting outward in the vehicle width direction from the front side frame is provided;
The first projecting portion is disposed on the lower side of the vehicle body with respect to the upper wall portion extending from the outer side surface of the front side frame to the outer side in the vehicle width direction. An impact load from the front, comprising: a lower wall portion extending outward in the vehicle width direction from a side surface on the outer side in the vehicle width direction; and a side wall portion connecting the outer end portions in the vehicle width direction of the upper wall portion and the lower wall portion. And receiving the impact load from the first projecting portion to the front side frame,
The side wall portion of the first projecting portion is formed to be inclined inward in the vehicle width direction toward the rear of the vehicle body in a plan view,
In the longitudinal direction of the vehicle body, the first projecting portion is disposed immediately adjacent to an outer end portion in the vehicle width direction of the portion extending in the longitudinal direction of the vehicle body of the crash can .
In a plan view, the end portion on the vehicle width direction outer side of the portion extending in the vehicle body longitudinal direction of the crash can and the first projecting portion are arranged to overlap in the vehicle width direction,
The front side frame is configured to be bent and deformed by receiving an impact load through the first projecting portion .

Furthermore, the invention according to claim 2 of the present application is the invention according to claim 1 ,
A front end portion of the first projecting portion is joined to a plate-like member interposed between the crash can and the front side frame.

According to the first or second aspect of the invention, in the case of a so-called small overlap collision, the impact load can be received by the first projecting portion that projects outward from the front side frame in the vehicle width direction. Further, the side surface of the first projecting portion on the outer side in the vehicle width direction is formed so as to incline in the vehicle width direction toward the rear of the vehicle body in plan view, so that the impact received from the front in the first projecting portion. The load can be effectively transmitted to the front side frame.

  Therefore, according to the present invention, at the time of the small overlap collision, the impact load is effectively absorbed and dispersed in the front portion of the vehicle body, so that the impact transmitted to the passenger compartment side can be mitigated.

Further, according to the present invention, the shock front end of the first projecting portion, for positioning the side after the crash cans in the longitudinal direction of the vehicle body, the deformation of only crash cans without front side frame can be damaged during low-speed collision When absorbed, the repair cost can be reduced by avoiding damage to the first projecting portion.

  Furthermore, since the first projecting portion is provided on the rear side of the crash can in this way, both ends of the bumper are not interfered with the first projecting portion in the space outside the crash can in the vehicle width direction. It can be arranged. Therefore, for example, it is possible to adopt a design in which both ends of the bumper are smoothly curved backward so as to pass through the space on the side of the crash can and in front of the first protruding portion. The degree of freedom can be maintained well.

In particular, according to the invention described in claim 2 , since the front end portion of the first projecting portion and the front end portion of the front side frame are joined to the same plate-like member, the impact load due to the small overlap collision. Is input to the first projecting portion, the impact load is also distributed and input to the front side frame via the plate-like member, and an excessive impact load is concentrated on the first projecting portion. You can avoid that. Therefore, in the case of a small overlap collision, it is avoided that the first projecting portion is easily peeled off from the front side frame, and load transmission from the first projecting portion to the front side frame is reliably realized. Can do.

It is the top view which looked at the vehicle body front part structure shown in FIG. 1 from the arrow A direction of FIG. FIG. 2 is an enlarged plan view showing a left front side frame and its peripheral part in the vehicle body front part structure shown in FIG. 1. FIG. 2 is a bottom view showing a structure below a left front side frame in the vehicle body front part structure shown in FIG. 1. It is the front view which looked at the left front side frame and the 1st protrusion part from the vehicle body front side. It is the perspective view which looked at the 1st protrusion part shown in FIG. 5 and its peripheral part from the diagonally back of the vehicle width direction outside. It is the side view which looked at the 1st protrusion part shown in FIG. 5 from the vehicle width direction outer side.

It is a top view which shows the vehicle body front part structure of the vehicle which concerns on another embodiment of this invention. It is a top view which shows the vehicle body front part structure of the vehicle which concerns on a prior art example.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, terms indicating directions such as “front”, “rear”, “front / rear”, “left”, “right”, “left / right”, etc. It shall indicate the direction when the traveling direction is “front”.

  FIG. 1 is a side view schematically showing a vehicle body front part structure of a vehicle according to the present embodiment, and FIG. 2 is a schematic plan view thereof.

  As shown in FIGS. 1 and 2, a pair of left and right front side frames 4 (4 a, 4 b) extend in the front-rear direction of the vehicle body in front of the dash panel 2 of the vehicle 1. A bumper beam 10 extends in the vehicle width direction at the front of the vehicle 1.

  The front end of the front side frame 4 is connected to both ends of the bumper beam 10 via the first crash can 6. A first mounting plate 7 disposed along a surface substantially perpendicular to the longitudinal direction of the vehicle body is fixed to the rear end portion of the first crash can 6 by welding, for example, and the front end portion of the front side frame 4 is A first set plate 8 disposed along a surface substantially orthogonal to the front-rear direction is fixed by, for example, welding. And in the connection part of the 1st crush can 6 and the front side frame 4, the 1st attachment plate 7 and the 1st set plate 8 which were mutually piled up are couple | bonded by the fastening of a volt | bolt, for example.

  With such a structure, when an impact load is input to the bumper beam 10 from the front, when the impact load is relatively small such as in the case of a low-speed collision, the front side frame 4 is not damaged and only the first crash can 6 is not damaged. If the impact load is so large that the impact load is so large that it cannot be absorbed by the deformation of the first crash can 6 alone, the front side frame 4 is crushed to effectively absorb the impact and The transmitted impact is suppressed.

  Further, a power unit 30 is disposed between the left and right front side frames 4a and 4b. The power unit 30 is supported by the left and right front side frames 4 via a support member 40 by, for example, suspension. In addition, illustration of the supporting member 40 is abbreviate | omitted in FIG.

  As the power unit 30, for example, a unit including an engine, a torque converter, and a transmission is mounted, and the weight of the power unit 30 occupies, for example, about 10 to 20% of the weight of the entire vehicle 1.

  However, in the present invention, the configuration of the power unit disposed between the left and right front side frames is not particularly limited as long as it includes a vehicle power source. For example, in the case of an electric vehicle. In addition, a power unit including a motor and a speed reducer may be mounted. In the case of a hybrid vehicle, a power unit including an engine, a motor, and a transmission may be mounted.

  FIG. 3 is an enlarged plan view showing the left front side frame 4a and its peripheral portion. FIG. 3 shows an example of a specific shape of the left end portion of the power unit 30. As shown in FIG. As shown in FIG. 3, the power unit 30 includes a parallel surface portion 32 that faces the left front side frame 4 a and is disposed substantially parallel in plan view. The parallel surface portion 32 is constituted by, for example, a part of the case of the transmission, but may be constituted by another member or part in the power unit 30. Although illustration is omitted, the right end portion of the power unit 30 is also provided with a parallel surface portion that faces the right front side frame 4b and is disposed substantially in parallel in a plan view, like the left end portion.

  As shown in the bottom view of FIG. 4, a sub-frame 16 that supports a suspension member (not shown) for the front wheel 14 is disposed below the front side frame 4. In FIG. 4, only the left half portion of the subframe 16 and its peripheral portion are shown, but the right half portion of the subframe 16 and its peripheral portion also have the same symmetrical structure.

  The subframe 16 includes a pair of left and right front vertical members 18 arranged to extend in the longitudinal direction of the vehicle body below the front side frames 4a and 4b, and a rear vertical length extending rearward from the rear end of the front vertical member 18. A member 20 and a front horizontal member 22 extending in the vehicle width direction so as to connect the front end portions of the left and right front vertical members 18 and a rear horizontal member extending in the vehicle width direction so as to connect the left and right rear vertical members 20 to each other. 24.

  For example, a substantially triangular second crush can 24 is connected to the front end of the front vertical member 18 of the subframe 16 in a plan view. A second mounting plate 25 disposed along a surface substantially orthogonal to the longitudinal direction of the vehicle body is fixed to the rear end portion of the second crash can 24 by, for example, welding, and the front end portion of the front vertical member 18 is A second set plate 26 disposed along a surface substantially orthogonal to the longitudinal direction of the vehicle body is fixed by welding, for example. And in the connection part of the 2nd crush can 24 and the front part vertical member 18, the 2nd attachment plate 25 and the 2nd set plate 26 which were mutually piled up are couple | bonded by fastening of the volt | bolt, for example.

  The second crash can 24 is disposed below the first crash can 6. Therefore, when the first crash can 6 is crushed at the time of a low-speed collision, the second crash can 24 can be crushed together with the first crash can 6, thereby more effectively absorbing the impact at the time of the low-speed collision. It is like that.

  In the vehicle body front structure of the vehicle 1 configured as described above, the vehicle width is further increased from the first projecting portion 50 protruding outward in the vehicle width direction from the front side frame 4 and the front vertical member 18 of the subframe 16. A second projecting portion 70 projecting outward in the direction is provided. Hereinafter, the structure of the 1st protrusion part 50 and the 2nd protrusion part 70 is demonstrated.

  First, the configuration of the first projecting portion 50 will be described with reference to FIGS. 3 and 5 to 7. Here, the configuration of the left first projecting portion 50 projecting from the left front side frame 4a shown in FIGS. 3 and 5 to 7 will be described, but the projecting projecting from the right front side frame 4b is described. The configuration of the first projecting portion 50 on the right side is the same as the configuration of the first projecting portion 50 on the left side, except that it has a symmetrical shape.

  As shown in FIG. 3, the first protruding portion 50 has a substantially triangular shape in plan view, and the side surface on the outer side in the vehicle width direction of the first protruding portion 50, that is, the side wall portion 55 is rearward of the vehicle body in plan view. Inclined inward in the vehicle width direction.

  Thereby, for example, as shown in FIG. 8, when a small overlap collision occurs between the vehicle 1 and the columnar collision object 99, the impact load is received by the first protruding portion 50, and the first protruding portion 50 to the front side frame 4 can be effectively transmitted.

  Returning to FIG. 3, the rear end portion of the first projecting portion 50 and the front end portion of the parallel surface portion 32 of the power unit 30 are disposed so as to overlap each other by a length L in the longitudinal direction of the vehicle body. In the overlapped range, the front side frame 4 and the parallel surface portion 32 of the power unit 30 are disposed to face each other with a substantially constant space therebetween. Therefore, during the small overlap collision, the front side frame 4 that is bent so as to protrude inward in the vehicle width direction due to the impact transmitted from the first projecting portion 50 can be reliably applied to the parallel surface portion 32 of the power unit 30. In this way, by receiving an impact load with the heavy power unit 30, the front side frame 4 is stably deformed in a manner as shown in FIG. 8, for example, and the shock absorption by the front side frame 4 is reliably realized. However, load distribution to the power unit 30 can also be achieved.

In the longitudinal direction of the vehicle body, the front end of the first projecting portion 50 is disposed immediately adjacent to the portion of the first crash can 6 including the central portion in the vertical direction of the vehicle body (see FIGS. 1 and 3). In a plan view, the first crash can 6 and the first projecting portion 50 are disposed so as to overlap in the vehicle width direction.

  Further, the front end of the first projecting portion 50 is disposed at the same position as the connecting portion between the first crash can 6 and the front side frame 4 in the longitudinal direction of the vehicle body. Therefore, when the impact is absorbed by the deformation of only the first crash can 6 without damaging the front side frame 4 at the time of a low-speed collision, it is possible to avoid the damage of the first projecting portion 50 and reduce the repair cost.

  Further, since the first projecting portion 50 is provided on the rear side of the first crash can 6, both end portions of the bumper 12 are disposed on the outer side in the vehicle width direction of the first crash can 6 as shown in FIG. 2. In this space, the first protruding portion 50 can be disposed without interfering with the first protruding portion 50. Therefore, for example, it is possible to adopt a design in which both end portions of the bumper 12 are smoothly curved backward so as to pass through the space in front of the first projecting portion 50 on the side of the first crash can 6. Thus, the degree of freedom in designing the front part of the vehicle body can be maintained satisfactorily.

  As shown in the front view of FIG. 5, the first projecting portion 50 includes a pair of upper and lower flange portions 51, 52 joined to the outer side surface of the front side frame 4 and the lower end of the upper flange portion 51. An upper wall portion 53 extending outward in the vehicle width direction, a lower wall portion 54 extending outward in the vehicle width direction from an upper end of the lower flange portion 52, and an outer end in the vehicle width direction of the upper wall portion 53 and the lower wall portion 54. It is a lightweight member having a substantially hat-shaped cross section including a side wall portion 55 that connects the portions.

  The first projecting portion 50 is formed, for example, by bending. Therefore, a high-strength material that cannot be used for press molding can be used as the material of the first projecting portion 50, thereby reducing the thickness of the first projecting portion 50, and thus the first projecting portion 50. Further weight reduction of the part 50 can be achieved.

  The front end of the first projecting portion 50 is joined to the first set plate 8 by welding, for example. Specifically, at the front end of the first projecting portion 50, the upper wall portion 53, the side wall portion 55, the lower wall portion 54, and the lower flange portion 52 are joined to the first set plate 8 by wire welding, for example.

  Thus, since not only the front side frame 4 but also the first projecting portion 50 is joined to the first set plate 8, the first set plate 8 is extended outward in the vehicle width direction compared to the conventional structure. Have a different shape.

  The first set plate 8 is formed with a plurality of openings 36 and 38, whereby the weight of the first set plate 8 is reduced. The front side frame 4 is a tubular member in which a front frame inner 46 and a front frame outer 47 are joined. The inner side surface of the front frame inner 46 and the outer side surface of the front frame outer 47 are respectively provided with ridges 48 and 49 extending in the longitudinal direction of the vehicle body, thereby increasing the strength of the front side frame 4. Yes. Further, the front side frame 4 is joined to the first set plate 8 by, for example, wire welding between the front frame inner 46 and the first set plate 8.

  As shown in FIGS. 6 and 7, the upper and lower flange portions 51, 52 of the first projecting portion 50 are extended in the longitudinal direction of the vehicle body, for example, spotted at a plurality of positions spaced in the longitudinal direction of the vehicle body. It is joined to the front frame outer 47 of the front side frame 4 by welding.

  The side wall portion 55 of the first projecting portion 50 is disposed along a substantially vertical direction. Further, the side wall portion 55 is formed such that the vertical width H (see FIG. 7) gradually increases toward the rear of the vehicle body, whereby the side wall portion 55 receives an impact load input from the front. It can be transmitted backward while being dispersed vertically. Further, since the vertical width of the side wall 55 is maximized at the rear end of the side wall 55, load transmission from the rear end of the side wall 55 to the power unit 30 is realized in a wide range in the vertical direction. can do. As described above, the front end of the side wall 55 is joined to the first set plate 8, but the rear end is not joined to the front side frame 4.

  A concave groove 56 formed by bead processing is formed at a substantially central portion in the vertical direction of the side wall portion 55 so as to extend in the longitudinal direction of the vehicle body, thereby increasing the strength against load input from the front. The concave groove 56 is formed so as to gradually become shallower toward the rear side of the vehicle body.

  Further, as described above, since the first projecting portion 50 is a light-weight member having a substantially hat-shaped cross section, when an impact load is input to the first projecting portion 50 from the front, The load applied to the joint portion between the pair of upper and lower flange portions 51 and 52 and the front side frame 4 is reduced.

  Furthermore, as described above, since the front end portion of the first projecting portion 50 and the front end portion of the front side frame 4 are joined to the same first set plate 8, the impact load due to the small overlap collision is the first. When input to the projecting portion 50, the impact load is distributed and input to the front side frame 4 via the first set plate 8, and excessive impact load is concentrated on the first projecting portion 50. This is avoided.

  For these reasons, even when an impact load is directly input from the collision object 99 to the first projecting portion 50 during the small overlap collision, the first projecting portion 50 is easily peeled off from the front side frame 4. The first projecting portion 50 can reliably receive the impact load and transmit it to the front side frame 4 without fail.

  Then, the structure of the 2nd protrusion part 70 is demonstrated, referring FIG.

  As described above, the second projecting portion 70 is provided so as to project outward from the front vertical member 18 of the subframe 16 in the vehicle width direction. The 2nd protrusion part 70 is comprised with the lightweight member of the cross-sectional U shape open | released toward a vehicle width direction inner side, for example.

  The inner end of the second projecting portion 70 in the vehicle width direction is joined to the front vertical member 18 of the subframe 16 by, for example, wire welding, and the front end of the second projecting portion 70 is, for example, by wire welding, the second set plate. 26 is joined.

  Thus, since not only the sub-frame 16 but also the second projecting portion 70 is joined to the second set plate 26, the second set plate 26 is extended outward in the vehicle width direction compared to the conventional structure. Has a shape.

  The second projecting portion 70 has a substantially triangular shape in plan view, and the positions of the front end and the inner end portion in the vehicle width direction are substantially the same as the first projecting portion 50, and the outer end portion in the vehicle width direction is It arrange | positions so that it may become an inner side rather than the 1st protrusion part 50. FIG. That is, the second projecting portion 70 is provided so as to overlap the first projecting portion 50 in plan view.

  Therefore, similarly to the first projecting portion 50, the second projecting portion 70 disposed below the first projecting portion 50 can receive an impact load at the time of the small overlap collision. Can be effectively transmitted from the second projecting portion 70 to the sub-frame 16, and shock absorption by the sub-frame 16 can be promoted. Thereby, the impact load at the time of the small overlap collision can be effectively absorbed by the front side frame 4 and the sub frame 16 while being distributed to the front side frame 4 and the sub frame 16. The impact transmitted to can be more effectively mitigated.

  Further, since the front end portion of the second projecting portion 70 and the front end portion of the sub-frame 16 are joined to the same second set plate 26, an impact load due to a small overlap collision is input to the second projecting portion 70. When this is done, the impact load is also distributed and inputted to the subframe 16 via the second set plate 26, and it is avoided that an excessive impact load is applied to the second projecting portion 70 in a concentrated manner. Therefore, it is possible to prevent the second projecting portion 70 from being easily peeled off from the subframe 16, and to effectively realize load transmission from the second projecting portion 70 to the subframe 16.

  In the present embodiment, the entire second projecting portion 70 is configured to overlap the first projecting portion 50 in a plan view, but the second projecting portion 70 and the first projecting portion 50 in a plan view. The same effect can be obtained even when and partially overlap.

  While the present invention has been described with reference to the above-described embodiments, the present invention is not limited to the above-described embodiments.

  As described above, according to the present invention, in the vehicle body front structure in which the bumper beam and the front side frame are coupled via the crash can, the repair cost when the crash can is damaged due to the low-speed collision is suppressed. Since it is possible to mitigate the impact transmitted to the passenger compartment side at the time of a small overlap collision while maintaining a good design freedom of the front part of the vehicle body, it is suitably used in the manufacturing industry of this type of vehicle. There is a possibility.
