Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in recent years, a structure that uses the upper surface of a battery case as a floor panel is known. Here, in a structure that does not use a floor panel, the floor cross member is required to have load-bearing performance against both the load input in the vehicle width direction and the load input in the vehicle vertical direction during a side collision of the vehicle. On the other hand, when the cross-sectional area of the floor cross member is enlarged, it becomes impossible to secure a wide passenger compartment space. Therefore, there is room for improvement in maintaining the load-bearing performance while suppressing the enlargement of vehicle skeleton members such as the floor cross member.

[0005] An object of the present invention is to obtain a vehicle skeleton member that can maintain load-bearing performance while suppressing enlargement.

Means for Solving the Problems

[0006] The vehicle frame member according to claim 1 has an outer component with a hat-shaped cross-section that extends in the vehicle width direction, is joined to the upper surface of the battery case and is open on the lower side of the vehicle when viewed from the vehicle width direction, and an inner component that is provided between the battery case and the outer component and forms a closed cross-section with respect to the outer component, wherein the inner component includes a vertical wall portion that extends in the vehicle vertical direction and a frame-shaped portion that is formed in a frame shape when viewed from the vehicle width direction.

[0007] The vehicle frame member according to claim 1 has an outer component and an inner component, the outer component is formed in a hat-shaped cross-section with the lower side of the vehicle open when viewed from the vehicle width direction. The outer component extends in the vehicle width direction and is joined to the upper surface of the battery case. The inner component is provided between the battery case and the outer component and forms a closed cross-section with the outer component. As a result, a closed cross-section is formed between the outer component and the battery case, and a closed cross-section is formed within this closed cross-section by the outer component and the inner component, so the rigidity can be improved without increasing the size of the vehicle frame member.

[0008] Furthermore, the inner structure includes vertical wall sections extending in the vehicle's vertical direction and frame-shaped sections formed in a rectangular frame shape when viewed from the vehicle's width direction. By providing these vertical wall sections, the resistance to loads applied in the vehicle's vertical direction can be improved.

[0009] The vehicle frame member according to claim 2 is provided in claim 1, wherein a fastening portion is provided on the upper part of the outer component at a position that overlaps with the vertical wall portion in a plan view, and a cover for electronic equipment is fastened to it.

[0010] In the vehicle frame member according to claim 2, since the fastening portion of the cover is provided at a position that overlaps with the vertical wall portion in a plan view, the load input from the cover to the vehicle frame member can be effectively received by the vertical wall portion.

[0011] The vehicle frame member according to claim 3 is characterized in that the frame-shaped portion is fixed to the upper end of the outer component in claim 2.

[0012] In the vehicle frame member according to claim 3, the rigidity of the upper end of the outer component can be improved by the frame-shaped portion. Furthermore, because the frame-shaped portion is formed in a frame shape, it does not interfere with bolts and nuts when they are placed in the fastening portion.

[0013] The vehicle frame member according to claim 4, in claim 1, comprises an inner component comprising: a front flange portion extending in the longitudinal direction along the battery case; a front vertical wall component extending upward from the rear end of the front flange portion; a rear flange portion extending in the longitudinal direction along the battery case behind the front flange portion; a rear vertical wall component extending upward from the front end of the rear front flange portion and joined to the front vertical wall component; and a frame-shaped portion connecting the upper end of the front vertical wall component and the upper end of the rear vertical wall component.

[0014] In the vehicle frame member according to claim 4, the inner component includes a front flange portion, a front vertical wall component, a rear flange portion, a rear vertical wall component, and a frame-like portion, and can be easily formed by press-forming a steel plate. Furthermore, since the front vertical wall component and the rear vertical wall component are joined to form the vertical wall portion, the load-bearing capacity can be improved compared to the case where the vertical wall portion is formed from a single steel plate.

[0015] The vehicle frame member according to claim 5 is configured in claim 4 such that the frame-shaped portion includes a front bottom portion extending forward from the upper end of the front vertical wall component and a rear bottom portion extending rearward from the upper end of the rear vertical wall component, wherein the rear bottom portion and the rear bottom portion are formed in a position that overlaps with partition portions that divide the interior of rockers provided on both sides in the vehicle width direction and extending in the vehicle longitudinal direction, when viewed from the vehicle width direction.

[0016] In the vehicle frame member according to claim 5, the frame-shaped portion is configured to include a front bottom portion and a rear bottom portion, and the front bottom portion and the rear bottom portion are formed at positions overlapping with a partition portion that vertically partitions the inside of the rocker when viewed from the vehicle width direction. Thereby, a part of the load input to the rocker during a side collision can be transmitted substantially linearly from the partition portion to the front bottom portion and the rear bottom portion. As a result, the collision load can be effectively transmitted.

Effect of the Invention

[0017] As described above, according to the vehicle frame member of the present invention, it is possible to maintain the load-bearing performance while suppressing the increase in size.

Mode for Carrying Out the Invention

[0019] The floor cross member 10 as a vehicle frame member according to the embodiment will be described with reference to the drawings.

[0020] FIG. 1 is a side sectional view showing a main part of a vehicle V provided with a floor cross member 10 according to an embodiment. In the figure, the arrows FR, UP, and LH indicate the vehicle front direction, the vehicle upward direction, and the vehicle left direction in the vehicle V, respectively. In the following description, when the front-rear, up-down, and left-right directions are used without special mention, the front-rear in the vehicle front-rear direction, the up-down in the vehicle up-down direction, and the left-right in the vehicle left-right direction (width direction) are respectively indicated.

[0021] As shown in FIG. 1, the vehicle V of the present embodiment includes a battery BT. The battery BT is disposed at the bottom of the vehicle V and is housed in a battery case 12. The battery BT is used as a secondary battery capable of storing electric power for supplying a drive motor (not shown).

[0022] In addition to a BEV (Battery Electric Vehicle) that uses only a motor as a drive source, the vehicle V can be widely applied to vehicles that use electric power as at least part of the drive source, such as a hybrid vehicle (HV: Hybrid Vehicle) and a plug-in hybrid vehicle (PHEV: Plug-in Hybrid Electric Vehicle).

[0023] The battery case 12 is formed of, for example, metal, includes an upper case 14 that covers the battery BT from above, and a floor cross member 10 is provided on the upper surface of the upper case 14. Note that the material of the battery case 12 is not particularly limited, and the battery case 12 may be formed of, for example, resin or the like.

[0024] As shown in FIG. 2, the floor cross member 10 extends in the vehicle width direction. The floor cross member 10 includes an outer constituent part 20 that constitutes the outside and an inner constituent part 21 provided inside the outer constituent part 20.

[0025] Fastening holes 20A as fastening parts are formed on the upper surface of the floor cross member 10. A plurality of fastening holes 20A are formed at intervals in the vehicle width direction. In FIG. 2, two fastening holes 20A are shown, but three or more fastening holes 20A may be formed.

[0026] As shown in Figure 1, a cover 16 is fastened to the upper end of the floor cross member 10. The cover 16 is made of, for example, resin, and covers the electronic equipment 100. The electronic equipment 100 covered by the cover 16 is not particularly limited, but for example, a converter such as an inverter and a converter may be considered the electronic equipment 100. Alternatively, an auxiliary battery may also be considered the electronic equipment 100.

[0027] The cover 16 bulges upward towards the vehicle in accordance with the shape of the electronic device 100, and the front end 16A of the cover 16 is fastened to the upper end of the floor cross member 10.

[0028] (Floor cross member 10) As shown in Figure 3, the floor cross member 10 is composed of an outer component 20 and an inner component 21. The outer component 20 is joined to the upper surface of the battery case 12 and is a metal member formed in a roughly hat-shaped cross section with the lower side of the vehicle open when viewed from the vehicle width direction.

[0029] Specifically, the outer component 20 is composed of a front flange portion 22, a front wall portion 24, an upper wall portion 26, a rear wall portion 28, and a rear flange portion 30, and is formed, for example, by press working.

[0030] The front flange portion 22 extends along the battery case 12 in the longitudinal direction of the vehicle and is joined to the battery case 12 together with the front flange portion 42 of the inner component 21, which will be described later. The front wall portion 24 extends in the vertical direction of the vehicle, and the lower end of the front wall portion 24 is connected to the rear end of the front flange portion 22. The upper end of the front wall portion 24 is connected to the front end of the upper wall portion 26.

[0031] The upper wall portion 26 extends in the longitudinal direction of the vehicle, and its front end is connected to the upper end of the front wall portion 24. The rear end of the upper wall portion 26 is connected to the upper end of the rear wall portion 28. The rear wall portion 28 extends in the vertical direction of the vehicle, and its upper end is connected to the rear end of the upper wall portion 26. Furthermore, the lower end of the rear wall portion 28 is connected to the front end of the rear flange portion 30.

[0032] The rear flange portion 30 extends along the battery case 12 in the longitudinal direction of the vehicle and is joined to the battery case 12 together with the rear flange portion 50 of the inner component 21, which will be described later. In this way, since the front flange portion 22 and the rear flange portion 30 of the outer component 20 are joined to the battery case 12, the outer component 20 and the battery case 12 form a closed cross section.

[0033] The inner component 21 is a metal member provided between the battery case 12 and the outer component 20, forming a closed cross-section with respect to the outer component 20. Specifically, the inner component 21 includes a front flange portion 42, a front vertical wall component 44, a rear flange portion 50, a rear vertical wall component 48, and a frame-shaped portion 46.

[0034] The front flange portion 42 extends along the battery case 12 in the vehicle's longitudinal direction and is formed to be longer in the vehicle's longitudinal direction than the front flange portion 22 of the outer component 20. The front end of the front flange portion 42 is superimposed on the lower surface of the front flange portion 22 of the outer component 20 and is joined to the battery case 12 together with the front flange portion 22 by welding or other means. Alternatively, the front flange portion 22 of the outer component 20 and the front flange portion 42 of the inner component 21 may be mechanically joined by fasteners such as bolts and rivets while they are superimposed.

[0035] The front vertical wall component 44 extends upward from the rear end of the front flange portion 42, and the length of the front vertical wall component 44 in the vehicle's vertical direction is shorter than the length of the front wall portion 24 of the outer component 20. The upper end of the front vertical wall component 44 is connected to the frame-shaped portion 46.

[0036] A rear flange portion 50 is positioned behind the front flange portion 42, extending in the front-rear direction along the battery case 12. The rear flange portion 50 is longer than the rear flange portion 30 of the outer component 20 and is approximately the same length as the front flange portion 42. The rear end of the rear flange portion 50 is superimposed on the lower surface of the rear flange portion 30 of the outer component 20 and is joined to the battery case 12 together with the rear flange portion 30 by welding or other means. Alternatively, the rear flange portion 30 of the outer component 20 and the rear flange portion 50 of the inner component 21 may be mechanically joined by fasteners such as bolts and rivets while they are superimposed.

[0037] The rear vertical wall component 48 extends upward from the front end of the rear flange portion 50, and the length of the rear vertical wall component 48 in the vehicle's vertical direction is shorter than the length of the rear wall portion 28 of the outer component 20. The upper end of the rear vertical wall component 48 is connected to the frame-shaped portion 46.

[0038] Here, the front vertical wall component 44 and the rear vertical wall component 48 are overlapped in the longitudinal direction of the vehicle and joined by welding or the like. The front vertical wall component 44 and the rear vertical wall component 48 constitute the "vertical wall portion" of the present invention. In other words, the vertical wall portion of the present invention is composed of two steel plates that extend in the vertical direction of the vehicle.

[0039] The frame-shaped portion 46 is formed in a frame shape and connects the upper end of the front vertical wall component 44 and the upper end of the rear vertical wall component 48. Specifically, the frame-shaped portion 46 is formed in a substantially rectangular frame shape when viewed from the vehicle width direction and includes a front bottom portion 46A extending forward from the upper end of the front vertical wall component 44 and a rear bottom portion 46B extending rearward from the upper end of the rear vertical wall component 48.

[0040] The front bottom portion 46A extends in the longitudinal direction of the vehicle, substantially parallel to the front flange portion 42, and the front end of the front bottom portion 46A is located near the front wall portion 24 of the outer component 20. In addition, the inner front wall portion 46C extends upward from the front end of the front bottom portion 46A towards the vehicle.

[0041] The inner front wall portion 46C extends in the vertical direction of the vehicle, and its lower end is connected to the front end of the front bottom portion 46A. The upper end of the inner front wall portion 46C abuts against the upper wall portion 26 of the outer component 20.

[0042] The rear bottom portion 46B extends in the longitudinal direction of the vehicle, substantially parallel to the rear flange portion 50, and its rear end is located near the rear wall portion 28 of the outer component 20. In addition, the inner rear wall portion 46D extends upward from the rear end of the rear bottom portion 46B towards the vehicle.

[0043] The inner rear wall portion 46D extends in the vertical direction of the vehicle, and its lower end is connected to the rear end of the rear bottom portion 46B. The upper end of the inner rear wall portion 46D abuts against the upper wall portion 26 of the outer component 20.

[0044] The upper end of the inner front wall portion 46C and the upper end of the inner rear wall portion 46D are connected in the longitudinal direction of the vehicle by the inner upper wall portion 46E. The inner upper wall portion 46E extends in the longitudinal direction of the vehicle and is joined to the upper wall portion 26 of the outer component 20 in a state where it overlaps with the lower surface of the upper wall portion 26 of the outer component 20. In other words, the frame-shaped portion 46 is fixed to the upper end of the outer component 20.

[0045] As described above, the outer component 20 and the inner component 21 are formed, and three closed sections are formed inside the outer component 20. Specifically, the front wall 24, the front flange 42, the front vertical wall component 44, the front bottom 46A, and the inner front wall 46C form a closed section. In addition, the rear wall 28, the rear flange 50, the rear vertical wall component 48, the rear bottom 46B, and the inner rear wall 46D form a closed section. Furthermore, the frame-shaped portion 46 forms a closed section.

[0046] A fastening hole 20A is formed in the central part of the upper wall portion 26 of the outer component 20 in the vehicle's longitudinal direction. In addition, a communication hole 21A is formed in the central part of the inner upper wall portion 46E of the inner component 21 in the vehicle's longitudinal direction, communicating with the fastening hole 20A. The communication hole 21A is formed at a position corresponding to the fastening hole 20A, and a bolt 54 is inserted through both the fastening hole 20A and the communication hole 21A.

[0047] A weld nut 52 is provided on the inner upper wall portion 46E of the inner component 21, and the cover 16 is fastened to the upper end of the floor cross member 10 by screwing a bolt 54 into the weld nut 52 with the cover 16 in between.

[0048] Here, the fastening hole 20A, which serves as the fastening portion to which the cover 16 is fastened, is formed in a position that overlaps with the front vertical wall component 44 and the rear vertical wall component 48 in a plan view. In this embodiment, as an example, the fastening hole 20A and the communication hole 21A are formed to be approximately the same size, but this is not limited to this, and they may be formed to be different sizes. For example, by forming the communication hole 21A to be smaller in diameter than the fastening hole 20A, the fixing space for the weld nut 52 may be secured.

[0049] Figure 4 is a schematic front view showing the main parts of the vehicle V according to the embodiment. As shown in Figure 4, rockers 60, which are structural members, are provided on both sides of the vehicle V in the vehicle width direction. Although only the left rocker 60 is shown in Figure 4, a similar rocker 60 is also provided on the right side.

[0050] The rocker 60 extends in the longitudinal direction of the vehicle and has a closed cross-sectional structure with a substantially rectangular cross-section. In this embodiment, the rocker 60 is formed by metal extrusion molding as an example, but it is not limited to this, and the rocker 60 may also be formed by joining two steel plates.

[0051] Below the rocker 60, the vehicle-width end of the battery case 12 is positioned, and the battery case 12 is fixed to the rocker 60 by fasteners such as bolts and nuts (not shown).

[0052] In this configuration, the rocker 60 is provided with a partition 60A that divides the internal space vertically. The partition 60A is located slightly above the vertical center of the rocker 60 and extends in the vehicle width direction. The right end of the partition 60A is joined to the right inner wall of the rocker 60, and the left end of the partition 60A is joined to the left inner wall of the rocker 60. In this embodiment, the main body of the rocker 60 and the partition 60A are integrally formed by extrusion molding.

[0053] The height of the partition 60A is the same as the height of the front bottom portion 46A and the rear bottom portion 46B that constitute the floor cross member 10. In other words, when viewed from the vehicle width direction, the front bottom portion 46A and the rear bottom portion 46B are formed in a position that overlaps with the partition 60A.

[0054] (action) Next, the operation of the vehicle frame member according to this embodiment will be explained.

[0055] As shown in Figure 3, the vehicle frame member according to this embodiment has an outer component 20 and an inner component 21. The outer component 20 is formed in a hat-shaped cross section with an open lower side when viewed from the vehicle width direction. The outer component 20 extends in the vehicle width direction and is joined to the upper surface of the battery case 12. The inner component 21 is provided between the battery case 12 and the outer component 20, forming a closed cross section with the outer component 20. As a result, a closed cross section is formed between the outer component 20 and the battery case 12, and a closed cross section is formed within this closed cross section by the outer component 20 and the inner component 21, so the rigidity can be improved without increasing the size of the floor cross member 10.

[0056] Furthermore, the inner component 21 is composed of vertical wall components (front vertical wall component 44, rear vertical wall component 48) that extend in the vertical direction of the vehicle, and a frame-shaped component 46 that is formed in a rectangular frame shape when viewed from the vehicle width direction. By providing these vertical wall components, the load-bearing capacity against loads applied in the vertical direction of the vehicle can be improved. Thus, according to the present invention, it is possible to maintain load-bearing performance while suppressing an increase in the size of the floor cross member 10.

[0057] Furthermore, in the floor cross member 10 of this embodiment, fastening holes 20A, which are fastening parts of the cover 16, are provided at positions that overlap with the front vertical wall component 44 and the rear vertical wall component 48 in a plan view. Therefore, the load input from the cover 16 to the floor cross member 10 can be effectively received by the vertical wall components, the front vertical wall component 44 and the rear vertical wall component 48. In particular, in this embodiment, since the vertical wall is constructed by overlapping two steel plates, the front vertical wall component 44 and the rear vertical wall component 48, the load-bearing capacity can be improved compared to when the vertical wall is constructed from a single steel plate.

[0058] Furthermore, in the floor cross member 10 of this embodiment, the rigidity of the upper end of the outer component 20 can be improved by the frame-shaped portion 46. As a result, for example, even in a structure where the floor cross member 10 supports a vehicle seat, the load from the vehicle seat can be received without increasing the size of the floor cross member 10.

[0059] Furthermore, because the frame-shaped portion 46 is formed in a frame shape, even when a bolt 54 is inserted through the fastening hole 20A and the communication hole 21A, it does not interfere with the frame-shaped portion 46. In other words, the tip of the bolt 54 and the weld nut 52 can be positioned within the closed cross-section of the frame-shaped portion 46.

[0060] Furthermore, in the floor cross member 10 of this embodiment, the inner component 21 is composed of a front flange portion 42, a front vertical wall component 44, a rear flange portion 50, a rear vertical wall component 48, and a frame-shaped portion 46, so the inner component 21 can be easily formed by press-forming a steel plate.

[0061] Furthermore, as shown in Figure 4, in this embodiment, the frame-shaped portion 46 is composed of a front bottom portion 46A and a rear bottom portion, and the front bottom portion 46A and the rear bottom portion 46B are formed in a position that overlaps with the partition portion 60A that divides the inside of the rocker 60 vertically when viewed from the vehicle width direction. As a result, a portion of the load input to the rocker 60 during a side collision can be transmitted in a substantially linear manner from the partition portion 60A to the front bottom portion 46A and the rear bottom portion 46B. As a result, the collision load can be transmitted effectively.

[0062] The floor cross member 10 according to the present invention has been described above, but it goes without saying that it can be implemented in various forms without departing from the spirit of the present invention. For example, as shown in Figure 3, in the above embodiment, the front vertical wall component 44 and the rear vertical wall component 48 of the inner component 21 are joined, but it is not limited to this. Also, in the above embodiment, the inner upper wall component 46E of the frame-shaped component 46 is joined to the upper wall component 26, but it is not limited to this, and a gap may be provided between the frame-shaped component 46 and the upper wall component 26.

[0063] Furthermore, in the above embodiment, the inner component 21 may have other shapes as long as it includes a vertical wall portion and a frame-shaped portion. For example, the front vertical wall component 44 and the rear vertical wall component 48 may be formed in a substantially wave-like shape when viewed from the side. Also, a part of the front vertical wall component 44 may bulge out toward the front of the vehicle. For example, by bulging the central part of the front vertical wall component 44 in the vertical direction of the vehicle toward the front of the vehicle and abutting it against the front wall portion 24, the number of closed cross sections and ridges inside the outer component 20 increases, and the load-bearing capacity can be improved. The same applies to the rear vertical wall component 48. However, as in this embodiment, if a space is secured between the front wall portion 24 and the front vertical wall component 44, a separate weld nut can be provided in this space, which is preferable because it allows other members to be fastened to the front of the floor cross member 10. Similarly, if a space is secured between the rear wall portion 28 and the rear vertical wall component 48, a separate weld nut can be provided in this space, which is preferable because it allows other members to be fastened to the rear of the floor cross member 10.
