Description

Technical Field

[0001] The technology disclosed in this specification relates to a lower bumper reinforcement and a vehicle, and more particularly to a structure equipped with the lower bumper reinforcement. Background Art

[0002] Japanese Patent Application Laid-Open No. 2017-94972 describes a vehicle equipped with a lower bumper reinforcement. When the vehicle collides with various obstacles, such as a collision test barrier, the lower bumper reinforcement can be used to withstand the collision load. Summary of the Invention

[0003] The lower the lower bumper reinforcement is positioned, the less overlap there is between the lower end of the lower bumper reinforcement and the lower end of the obstacle. In other words, the vertical distance between the lower bumper reinforcement and the space below the obstacle becomes shorter. Consequently, when this structure collides with an obstacle, the lower bumper reinforcement may infiltrate the space below the obstacle. In this case, it becomes difficult for the lower bumper reinforcement to properly withstand the impact load.

[0004] A vehicle according to a first embodiment of the present invention is equipped with a vehicle body. The vehicle is equipped with a front bumper reinforcement, which is mounted at the front end of the vehicle body and extends in the vehicle width direction. The vehicle is equipped with a lower bumper reinforcement, which is mounted at the front end of the vehicle body, is located below the front bumper reinforcement, and extends in the vehicle width direction. The vehicle is equipped with at least one specific component, which is fixed to a portion of the extension direction of the lower bumper reinforcement. Each of the specific components is equipped with a first portion covering the front surface of the lower bumper reinforcement and a second portion protruding upward from the upper surface of the lower bumper reinforcement.

[0005] The inventors and others have discovered that when the pressure area of ​​the lower bumper reinforcement (the area of ​​the region that bears the collision load) is small, the lower bumper reinforcement may dig under an obstacle. One of the main reasons for this is that due to the concentrated load input to the lower bumper reinforcement, local deformation such as the movement of the lower bumper reinforcement downward is likely to occur. Therefore, in the above-mentioned vehicle, the second part can be used to increase the pressure area of ​​the collision load. Since the collision load input to the lower bumper reinforcement becomes difficult to concentrate, the occurrence of local deformation such as the movement of the lower bumper reinforcement downward can be suppressed. The phenomenon of the lower bumper reinforcement digging under an obstacle can be suppressed. In addition, since the first part covers the front surface of the lower bumper reinforcement, the collision load received by the second part can be transferred to the lower bumper reinforcement via the first part. The lower bumper reinforcement can be used to properly bear the collision load.

[0006] In the vehicle according to the above aspect, the vertical length of each specific member can be longer than the vertical length of the lower bumper reinforcement.

[0007] In the vehicle according to the above embodiment, each of the specific members may further include a protrusion that projects rearward from the second portion and contacts the upper surface of the lower bumper reinforcement. The protrusion can suppress rearward deformation of the second portion, thereby appropriately supporting the second portion against collision loads.

[0008] The vehicle according to the above-described method may further include a pair of crash boxes extending in the front-to-rear direction of the vehicle. The rear end of the crash box may also be connected to the lower portion of the vehicle body. The front end of the crash box may also be connected to the lower bumper reinforcement. When viewed from the front of the vehicle, at least a portion of the first portion may also overlap with the front end of the corresponding crash box. As a result, the collision load input to the first portion can be directly transferred to the crash box. The collision load can be efficiently transferred to the crash box.

[0009] In the vehicle according to the above aspect, the first portion may be located further inward in the vehicle width direction than the outer side wall of the corresponding crash box, when viewed from the front of the vehicle. A region where the first portion is not located may be formed at the front end of the crash box.

[0010] In the vehicle according to the above embodiment, a portion of the first portion may be located further inward in the vehicle width direction than the inner sidewall of the corresponding crash box, when viewed from the front of the vehicle. This allows the first portion to overlap with the inner sidewall of the crash box, effectively transmitting the collision load to the inner sidewall of the crash box.

[0011] The vehicle according to the above embodiment may further include a fixing member for securing the lower bumper reinforcement to the crash box. When viewed from the front of the vehicle, each fixing member may be located further inward in the vehicle width direction than the outer sidewall of the corresponding crash box, and further outward in the vehicle width direction than the outer end surface of the first portion. Thus, the fixing member may be positioned in an area at the front end of the crash box where the first portion is not located. This can prevent interference between the fixing member and the first portion during assembly of the fixing member.

[0012] In the vehicle according to the above embodiment, the vehicle body may be equipped with a subframe disposed at the lower portion of the vehicle body. A crash box may be connected to the front end of the subframe. This allows the collision load to be transmitted to the subframe via the crash box. The deformation of the subframe can be utilized to absorb the collision load.

[0013] The vehicle according to the above embodiment may further include an air intake grille disposed on the upper side of the lower bumper reinforcement. When viewed from the front of the vehicle, the air intake grille may be located further inward in the vehicle width direction than the inner end surface of the second portion in the vehicle width direction. This prevents interference between the second portion and the air intake grille, ensuring sufficient space for the air intake grille.

[0014] In the vehicle according to the above embodiment, the strength of the material of the specific member can be lower than that of the lower bumper reinforcement. This allows the specific member to deform more easily than the lower bumper reinforcement, thus preventing load from concentrating on the specific member when colliding with an obstacle.

[0015] In the vehicle according to the above aspect, the specific member may be spaced apart from the front surface of the lower bumper reinforcement.

[0016] A second aspect of the present invention relates to a lower bumper reinforcement for a vehicle. The lower bumper reinforcement includes at least one specific member fixed to a portion of the lower bumper reinforcement in its extending direction. Each of the specific members includes a first portion that covers the front surface of the lower bumper reinforcement and a second portion that protrudes upward from the upper surface of the lower bumper reinforcement.

[0017] In the lower bumper reinforcement according to the above aspect, the lower bumper reinforcement may be configured to be located below a front bumper reinforcement of the vehicle.

[0018] In the lower bumper reinforcement according to the above aspect, the length of each of the specific members in the up-down direction may be longer than the length of the lower bumper reinforcement in the up-down direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] <Vehicle front structure>

[0028] Figure 1 , a top view of the front structure of the vehicle according to the present embodiment is shown in FIG. Here, the direction FR in the figure indicates the front in the front-rear direction of the vehicle, and the direction RR indicates the rear in the front-rear direction of the vehicle. In addition, the direction LH indicates the left in the left-right direction (or width direction) of the vehicle, and the direction RH indicates the right in the left-right direction of the vehicle. Furthermore, the direction UP indicates the top in the up-down direction of the vehicle, and the direction DW indicates the bottom in the up-down direction of the vehicle. Furthermore, the directions described in the specification, such as "front-rear direction", "left-right direction", "up-down direction", "front", "rear", "left", "right", "up" and "down", respectively indicate directions in the vehicle. In the following figures, the meaning of the coordinate system is the same. In addition, since the vehicle of the present embodiment has a left-right symmetrical shape, sometimes only one side of the vehicle will be described below.

[0029] The vehicle is equipped with a subframe 10, a crash box 11, a lower bumper reinforcement 12, a specific component 13, and an air intake grille 14. In addition, on the upper side of these, there are a front longitudinal beam 20, a crash box 21, a front bumper reinforcement 22, and a cross beam 23. In order to make the drawings easier to understand, the front longitudinal beam 20, the crash box 21, the front bumper reinforcement 22, and the cross beam 23 are represented by dotted lines. The subframe 10, the front longitudinal beam 20, and the cross beam 23 are components that constitute the vehicle body. In addition, Figure 1 In the figure, the description of other components is omitted.

[0030] The front longitudinal members 20 form the framework of the front portion of the vehicle body. A pair of left and right longitudinal members 20 are positioned on either side of the vehicle width and extend in the vehicle's longitudinal direction. A cross member 23 connects the front ends of the pair of front longitudinal members 20 in the vehicle's width direction. A pair of crash boxes 21 are mounted to the front ends of the pair of front longitudinal members 20. The front bumper reinforcement 22 is mounted to the front ends of the pair of crash boxes 21. In other words, the front bumper reinforcement 22 is mounted to the front end of the vehicle body and extends in the vehicle's width direction.

[0031] In road-driving vehicles like automobiles, the subframe 10 is a structure primarily used to support the suspension (particularly the suspension arms). Subframe 10, also known as a suspension member, is located below the vehicle body. Specifically, subframe 10 is attached to the underside of a pair of front side members 20.

[0032] A pair of crash boxes 11 extend in the vehicle's front-to-rear direction. The crash boxes 11 have a closed, generally rectangular cross-sectional structure. The rear ends of the crash boxes 11 are attached to the front ends of the subframe 10, thereby connecting them to the lower portion of the vehicle body. The front ends of the crash boxes 11 are connected to the lower bumper reinforcement 12 via brackets 11b. The crash boxes 11 are designed to compress and deform in the axial direction in response to loads exceeding a specified value from the lower bumper reinforcement 12.

[0033] The lower bumper reinforcement 12 is mounted on the front ends of the pair of crash boxes 21. Specifically, the lower bumper reinforcement 12 is attached to the front end of the vehicle body and extends in the vehicle width direction. Furthermore, the lower bumper reinforcement 12 is located below the front bumper reinforcement 22. A cross-section of the lower bumper reinforcement 12 perpendicular to the vehicle width direction forms a closed cross-section.

[0034] A pair of specific members 13 are fixed to a portion of the extending direction of the lower bumper reinforcement 12. The detailed structure of the specific members 13 will be described later.

[0035] The air intake grille 14 is a device that controls the flow of air to the radiator (not shown) by opening and closing the grille according to the operating conditions. The air intake grille 14 is arranged above the lower bumper reinforcement 12 and below the front bumper reinforcement 22.

[0036] <Structure of specific member 13>

[0037] Next, use Figures 2 to 5 The structure of the specific component 13 is described. Figure 2 , a perspective view of the vicinity of a specific component 13 disposed on the right side of the vehicle is shown. Figure 2 In the figure, the subframe 10, the air intake grille 14, and the rear part of the crash box 11 are omitted. Figure 3In, it means from Figure 2 A front view of the vehicle viewed from the direction of arrow Y1 (i.e., a view viewed from the front of the vehicle). Figure 4 In, it means from Figure 2 The top view observed in the direction of arrow Y2. Figure 5 In, it means from Figure 2 Side view viewed from the direction of arrow Y3. Figure 3 and Figure 4 In FIG. 1 , the arrangement position of the air intake grille 14 is indicated by a single-dot chain line.

[0038] The specific member 13 is a member formed by bending a steel plate. Figure 2 As shown, the specific member 13 is secured to the lower bumper reinforcement 12 via weld regions WR1 and WR2. Weld region WR1 is where arc welding is performed at the contact portion between the specific member 13 and the front surface 12f of the lower bumper reinforcement 12. Weld region WR2 is where arc welding is performed at the contact portion between the specific member 13 and the upper surface 12u of the lower bumper reinforcement 12. Furthermore, the strength of the material of the specific member 13 is lower than that of the material of the lower bumper reinforcement 12.

[0039] The specific member 13 is provided with a first portion 13a, a second portion 13b, a protrusion 13c (see Figure 3 、 Figure 5 ). The first portion 13a is a portion that covers the front surface 12f of the lower bumper reinforcement 12. The second portion 13b is a portion that protrudes upward from the upper surface 12u of the lower bumper reinforcement 12. The protrusion 13c is a portion that protrudes rearward from the second portion 13b and contacts the upper surface 12u of the lower bumper reinforcement 12. The protrusion 13c is formed from a steel plate that is bent approximately perpendicularly relative to the second portion 13b. The protrusion 13c acts as a reinforcement that suppresses deformation of the second portion 13b toward the rear side. Therefore, it can properly withstand the collision load input to the second portion 13b.

[0040] like Figure 5 As shown, the vertical length H1 of the specific member 13 is longer than the vertical length H2 of the lower bumper reinforcement 12. This ensures a sufficient amount of upward projection of the second portion 13b from the upper surface 12u of the lower bumper reinforcement 12.

[0041] exist Figure 3 In the figure, the front end 11f of the crash box 11, which has a generally rectangular closed cross-sectional structure, is indicated by a dotted line. Furthermore, when viewed from the front of the vehicle, at least a portion of the first portion 13a of the specific member 13 overlaps with the front end 11f of the crash box 11. This allows the impact load applied to the first portion 13a to be directly transmitted to the crash box 11, effectively transferring the impact load to the crash box 11.

[0042] like Figure 3 and Figure 4 As shown, the crash box 11 includes an outer side wall 11o located on the vehicle widthwise outer side (i.e., the left side in the figure) and an inner side wall 11i located on the vehicle widthwise inner side (i.e., the right side in the figure). Furthermore, an end surface 13e1 is located on the vehicle widthwise outer side of the first portion 13a. The end surface 13e1 is located a distance D1 inward of the outer side wall 11o in the vehicle widthwise direction of the crash box 11. As a result, when viewed from the front of the vehicle, a region is formed at the front end 11f of the crash box 11 where the first portion 13a is not located.

[0043] Furthermore, an opening 12o formed in the front surface 12f of the lower bumper reinforcement 12 is located in an area where the first portion 13a is not disposed. Bolts 30 are disposed within the opening 12o to secure the lower bumper reinforcement 12 to the crash box 11. When viewed from the front of the vehicle, the bolts 30 are located further inward in the vehicle width direction than the outer sidewall 11o of the crash box 11 and further outward in the vehicle width direction than the end face 13e1 of the first portion 13a. Thus, the bolts 30 can be disposed in an area where the first portion 13a of the specific component 13 is not disposed at the front end portion 11f of the crash box 11. When the bolts 30 are assembled through the opening 12o, interference between the bolts 30 and the first portion 13a can be suppressed.

[0044] like Figure 3 and Figure 4 As shown, a portion R1 of the first portion 13a is located inward in the vehicle width direction (i.e., on the right side in the figure) relative to the inner sidewall 11i of the crash box 11. As a result, the first portion 13a can overlap the inner sidewall 11i of the crash box 11 when viewed from the front of the vehicle. This allows the collision load to be efficiently transmitted to the inner sidewall 11i of the crash box 11.

[0045] like Figure 4 As shown, a space SP is formed between the specific member 13 and the front surface 12f of the lower bumper reinforcement 12. In other words, the specific member 13 is spaced apart from the front surface 12f of the lower bumper reinforcement 12. Thus, the space SP can be formed between the specific member 13 and the front surface 12f of the lower bumper reinforcement 12. Figure 2 ) Arc welding can be performed appropriately. In addition, the space SP can be made to function as a collapse zone.

[0046] like Figure 3 and Figure 4As shown, end surface 13e2 is located inward of second portion 13b in the vehicle width direction. Furthermore, when viewed from the front of the vehicle, the air intake grille 14, indicated by a dashed line, is located inward of end surface 13e2 in the vehicle width direction. This prevents interference between second portion 13b of specific component 13 and crash box 14, ensuring sufficient space for the air intake grille 14.

[0047] The lower bumper reinforcement 12 is required to be designed so that concentrated loads are not applied to the obstacle when it collides with the obstacle. In the technology of this specification, the strength of the material of the specific member 13 is lower than that of the material of the lower bumper reinforcement 12. This allows the specific member 13 to deform more easily than the lower bumper reinforcement 12. The specific member 13 can be used to suppress the problem of concentrated loads on the obstacle.

[0048] <Effect>

[0049] use Figure 6 and Figure 7 The topic is explained using a side view of the . Figure 6 and Figure 7 A related art lower bumper reinforcement 112 is shown which is not equipped with the specific member 13 . Figure 6 Indicates the state before the collision, Figure 7 Indicates the state after the collision. Figure 6 and Figure 7 In the figure, for easy understanding, only the lower bumper reinforcement 112, the collision energy absorbing box 11, the subframe 10, and the barrier 40 are shown. Figure 6 As shown, there is an overlap amount WA from the lower end 112L of the lower bumper reinforcement 112 to the lower end 40L of the obstacle 40. Furthermore, the lower the position of the lower bumper reinforcement 112 relative to the horizon GL is set, the smaller the overlap amount WA becomes. In other words, the vertical distance between the lower end 112L of the lower bumper reinforcement 112 and the lower end 40L of the obstacle 40 becomes shorter. Figure 7 As shown, when the above structure collides with the obstacle 40, the lower bumper reinforcement 112 sometimes infiltrates into the space BS below the obstacle 40. In this case, it is difficult for the lower bumper reinforcement 112 to properly bear the collision load. As a result, there is a situation where the subframe 10 is not sufficiently deformed and the collision load is not fully absorbed by the subframe 10. In addition, the inventors of the present invention have found that when the pressure area (the area of ​​the region that bears the collision load) of the lower bumper reinforcement 112 is small, the lower bumper reinforcement 112 may infiltrate below the obstacle 40. One of the main reasons for this is that a concentrated load is input to the lower bumper reinforcement 112, and therefore, local deformation such as the lower bumper reinforcement 112 moving downward is likely to occur.

[0050] Therefore, in the technology of this specification, the specific member 13 is configured on the lower bumper reinforcement 12. And, by virtue of the second portion 13b equipped with the specific member 13, the pressure receiving area of ​​the collision load can be increased (refer to Figure 3 ). Since the collision load input to the lower bumper reinforcement 12 is not easily concentrated, the occurrence of local deformation such as the lower bumper reinforcement 12 moving downward can be suppressed. Even when the overlap amount WA is small, the phenomenon of the lower bumper reinforcement 12 diving into the lower side of the obstacle 40 can be stably suppressed. In addition, since the first portion 13a covers the front surface 12f of the lower bumper reinforcement 12, the collision load borne by the second portion 13b can be transmitted to the lower bumper reinforcement 12 via the first portion 13a. The lower bumper reinforcement 12 can appropriately bear the collision load. As a result, the collision load can be transmitted to the subframe 10 via the crash box 11. The collision load can be absorbed by causing the subframe 10 to deform sufficiently.

[0051] To increase the pressure-bearing area, one approach is to raise the height of the lower bumper reinforcement along its entire extension direction. However, this would result in an increase in mass. Furthermore, the space between the lower bumper reinforcement and the front bumper reinforcement would become narrower, making it difficult to fit the air intake grille 14 within this space. In the technology described herein, a pair of specific components 13 are positioned within a portion of the area along the extension direction of the lower bumper reinforcement 12. This allows for both suppressing mass increases and increasing the pressure-bearing area. Furthermore, space for the air intake grille 14 can be secured.

[0052] While specific examples of the technology disclosed in this specification have been described in detail above, these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various variations and modifications of the specific examples illustrated above. The technical features described in this specification or the drawings demonstrate technical utility individually or in various combinations, and are not limited to the combinations described in the claims at the time of filing. The technology illustrated in this specification or the drawings can achieve multiple objectives simultaneously, and achieving one of these objectives itself is technically useful.

[0053] <Modification>

[0054] The position of the specific member 13 in the vehicle width direction is not limited to the position described in this specification, and can be various. Figure 3 and Figure 4In the embodiment, the end surface 13e1 of the first portion 13a on the outside in the vehicle width direction may be located further outward in the vehicle width direction (i.e., on the left side in the figure) than the outside side wall 11o of the crash box 11. As a result, the first portion 13a can overlap both the inside side wall 11i and the outside side wall 11o of the crash box 11 when viewed from the front of the vehicle. This allows the collision load to be efficiently transferred to the inside side wall 11i and the outside side wall 11o.

[0055] The structure of the protrusion 13c can be various. For example, the protrusion 13c can be composed of a component independent of the specific member 13, or can be attached to the specific member 13 by welding or the like.

[0056] The method of fixing the specific member 13 to the lower bumper reinforcement 12 is not limited to arc welding, and various fixing methods can be used. For example, fastening members such as bolts can also be used.

[0057] There is no particular limitation on the number of the specific members 13 , and a single specific member 13 or three or more specific members 13 may be mounted on the lower bumper reinforcement 12 .

[0058] There is no particular limitation on the specific shape or structure of the specific member 13 or the lower bumper reinforcement 12. In addition, the shape of the specific member 13 is not limited to the plate shape as in this embodiment, but may also be a tubular shape with a closed cross section.

[0059] The vehicle structure of this embodiment is not limited to vehicles using an engine as a prime mover and can also be well applied to electric vehicles having an electric motor driving the wheels. Furthermore, the electric vehicles mentioned here include, for example, rechargeable electric vehicles charged by an external power source, fuel cell vehicles using a fuel cell as a power source, and hybrid vehicles that also have an engine.

[0060] The bolt 30 is an example of a fixing member.
