Description

[Technical Field]

[0001] The present invention relates to a vehicle body. [Background technology]

[0002] The following Patent Document 1 discloses an invention relating to a front body structure of a vehicle. This vehicle front body structure includes a suspension housing that is an aluminum alloy casting. Therefore, the prior art described below can reduce the number of parts compared to a structure in which a suspension housing is formed by joining multiple members by welding. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-166936 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above prior art, a damper that forms part of the suspension is attached to the suspension housing, but since the mounting position of the suspension varies depending on the vehicle specifications, etc., there is room for improvement in the above prior art from the perspective of standardizing the parts that make up the vehicle body.

[0005] SUMMARY OF THE INVENTION In consideration of the above, an object of the present invention is to provide a vehicle body that can reduce the number of parts that make up the vehicle body and can standardize the parts that make up the vehicle body. [Means for solving the problem]

[0006] The vehicle body according to the first aspect is provided with vehicle body components including an upper component that is a metal casting, extends in the vehicle width direction, and is capable of supporting a windshield glass; a lower component that extends in the vehicle width direction and is arranged along the front edge of the floor section, and is capable of supporting the floor section; a pair of side components that are capable of mounting suspension support sections that are capable of supporting part of the suspension, and that form part of the vehicle underside of the front pillar and connect the upper component and the lower component; and a partition that is integrated with the upper component, the lower component, and the side components, and that separates the vehicle interior from the power unit room.

[0007] The vehicle body according to the first aspect is provided with a vehicle body component having an upper component extending in the vehicle width direction, a lower component extending in the vehicle width direction, a pair of side components connecting the upper component and the lower component, and a partition wall portion integrated with the upper component, the lower component, and the side component.

[0008] Meanwhile, windshield glass shapes tend to be similar across vehicles of various specifications, and the shapes of the portions of the vehicle body that support the windshield glass also tend to be similar. Furthermore, while the height of the vehicle body floor tends to differ across vehicles of various specifications, the correlation between the vehicle body floor and the portions that support it tends to be similar. Furthermore, while the overall configuration of the front pillars across vehicles of various specifications tends to differ, the configuration of the portions below the front pillars tends to be similar. Furthermore, the configuration of the partition wall that separates the passenger compartment from the power unit compartment across vehicles of various specifications tends to be similar.

[0009] In this aspect, the upper component is capable of supporting a windshield glass, the lower component is disposed along the front edge of the floor and is capable of supporting the floor, the side component forms a part of the underside of the vehicle front pillar, and the partition separates the passenger compartment from the power unit compartment. The side component is also capable of mounting a suspension support part that can support part of a suspension, the mounting position of which tends to vary depending on the vehicle specifications, etc.

[0010] That is, in this aspect, parts of the vehicle body that can be shared among vehicles of various specifications are integrated into the vehicle body component, and parts of the vehicle body that are difficult to share among vehicles of various specifications are attached to the vehicle body component as separate parts.

[0011] In this aspect, the vehicle body component is a metal casting, and the upper component, the lower component, the side component, and the partition can be configured as a single component. Therefore, the number of parts that make up the vehicle body component can be reduced compared to a configuration in which the vehicle body component is configured by welding these components together using steel plates or the like.

[0012] The vehicle body of the second aspect is the vehicle body of the first aspect, in which a through-hole is formed in the partition portion that penetrates in the fore-and-aft direction of the vehicle, the through-hole is blocked by a dash panel component, and part of the brake device is attached to the dash panel component.

[0013] As described above, in the vehicle body according to the second aspect, the vehicle body component includes a partition wall that separates the passenger compartment from the power unit compartment, and this partition wall is located near the driver's seat. For example, it is conceivable that part of a brake device is attached to this partition wall.

[0014] However, the mounting position of the brake device tends to vary depending on the vehicle specifications, and if a configuration is adopted in which part of the brake device is directly mounted to the partition wall, it is necessary to set multiple mounting points for the brake device on the partition wall so that they correspond to the mounting position of the brake device according to the vehicle specifications.

[0015] In this embodiment, a through-hole is formed in the partition wall in the vehicle longitudinal direction, and this through-hole is closed by a dash panel component, to which part of the brake device is attached.

[0016] Therefore, in this aspect, by attaching a dash panel component having an attachment point corresponding to the attachment position of the brake device to the partition portion depending on the vehicle specifications, it is possible to attach part of the brake device to the vehicle body component without changing the shape of the vehicle body component.

[0017] A vehicle body according to a third aspect is the vehicle body according to the second aspect, wherein the dash panel components are made of resin.

[0018] According to the vehicle body of the third aspect, the dash panel components are made of resin, and therefore, by adjusting the resin molding die used to manufacture the dash panel components, it is possible to accommodate changes in the mounting position of the brake device on the vehicle.

[0019] The vehicle body of the fourth aspect is the vehicle body of the first aspect, further comprising a longitudinal skeleton portion extending in the longitudinal direction of the vehicle and attached to the front surface of the partition portion on the vehicle underside of the suspension support portion, and a reinforcing rib portion is formed on the rear surface of the partition portion on the vehicle rear side, protruding from the rear of the vehicle from the rear surface and extending from the longitudinal skeleton portion when viewed from the longitudinal direction of the vehicle.

[0020] A vehicle body according to a fourth aspect includes a longitudinal skeleton that extends in the longitudinal direction of the vehicle and is attached to the front surface of the partition wall at the front side of the vehicle, and this longitudinal skeleton constitutes a part of the skeleton at the front side of the vehicle body. The longitudinal skeleton is also located below the suspension support portion and can support the suspension support portion.

[0021] Incidentally, it is conceivable that vibrations from the suspension side are input to the partition wall through the suspension support portion and the longitudinal skeleton portion, causing vibrations in the partition wall.

[0022] In this aspect, a reinforcing rib is formed on the rear surface of the partition wall on the vehicle rear side, and this reinforcing rib protrudes from the rear surface of the partition wall toward the vehicle rear and extends from the longitudinal frame when viewed from the vehicle longitudinal direction. Therefore, in this aspect, the reinforcing rib ensures the rigidity of the partition wall against various vibrations and can suppress vibration of the partition wall due to vibrations from the suspension side. [Effects of the Invention]

[0023] As described above, the vehicle body according to the present invention has the excellent effect of being able to reduce the number of parts constituting the vehicle body and to standardize the parts constituting the vehicle body. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0025] An example of an embodiment of a vehicle body according to the present invention will be described below with reference to Figures 1 to 5. Note that the arrow FR shown in each figure indicates the front side of the vehicle, the arrow UP indicates the upper side of the vehicle, and the arrow LH indicates the left side in the vehicle width direction.

[0026] First, a general configuration of a "vehicle 12" equipped with a "vehicle body 10" according to this embodiment will be described with reference to FIG.

[0027] The vehicle body 10 includes a front part 14 that forms the front portion of the vehicle, a center part (not shown) that forms the center portion of the vehicle in the longitudinal direction and includes a battery and a battery frame that holds the battery, and a rear part (not shown) made of aluminum die-cast that forms the rear portion of the vehicle. In other words, the vehicle 12 is an electric vehicle. The vehicle body 10 is basically configured symmetrically, and the following description will focus on the configuration of the left portion of the vehicle body 10 in the vehicle width direction.

[0028] The front part 14 is made up of a "body component 16" which forms the rear part of the vehicle and is made of aluminum die-cast, a pair of apron upper members 18, a pair of "suspension towers 20" which serve as suspension support parts, a pair of "front side members 22" which serve as longitudinal skeleton parts, and a pair of suspension side rails 24.

[0029] In detail, as shown in Figures 2 and 3, the vehicle body component 16 is composed of an "upper component 16A" that constitutes the upper part of the vehicle, a "lower component 16B" that constitutes the lower part of the vehicle, a pair of "side component parts 16C" that constitute the outer parts in the vehicle width direction, and a "partition wall part 16D" that is formed integrally with the upper component part 16A, the lower component part 16B, and the side component parts 16C.

[0030] The upper constituent portion 16A extends in the vehicle width direction, and a cowl portion 25 is disposed on the upper side of the vehicle. The cowl portion 25 extends in the vehicle width direction and is configured to include a cowl lower panel 26 that forms the lower portion of the vehicle, and a cowl top panel 28 that forms the upper portion of the vehicle. The cowl portion 25 is attached to the upper constituent portion 16A by attachment members (not shown), and supports a "windshield glass 29" from the underside of the vehicle.

[0031] The lower constituent portion 16B extends in the vehicle width direction and is disposed along the front edge of a floor portion (not shown) whose main portion is constituted by a center part of the vehicle body 10. As also shown in Fig. 4, mounting piece portions 16B1 are provided at the outer ends of the lower constituent portions 16B in the vehicle width direction, and the floor portion of the vehicle body 10 is attached to these mounting piece portions 16B1 via mounting members (not shown).

[0032] The side constituent portion 16C extends in the vehicle vertical direction, constitutes the vehicle lower portion of the "front pillar 10A" of the vehicle body 10, and connects the upper constituent portion 16A and the lower constituent portion 16B in the vehicle vertical direction. An apron upper member 18 is disposed on the vehicle front side of the side constituent portion 16C.

[0033] The apron upper member 18 is formed by joining a plurality of pressed steel plates at joints (not shown) by welding or the like, and extends in the fore-and-aft direction of the vehicle and extends from an upper portion of the side constituent portion 16C toward the front of the vehicle. The side constituent portion 16C is provided with a plurality of female threads, and the apron upper member 18 is fixed to the side constituent portion 16C via fixing members (not shown) fastened to the female threads. A suspension tower 20 is disposed on the inner side of the apron upper member 18 in the vehicle width direction.

[0034] The suspension tower 20 is formed into a box shape with an open underside to the vehicle by joining a plurality of pressed steel plates by welding or the like at joints (not shown), and the end of a damper of a shock absorber (not shown) is attached to the top surface of the suspension tower 20. The apron upper member 18 is provided with a plurality of female threads, and the suspension tower 20 is fixed to the apron upper member 18 via fixing members (not shown) that are fastened to the female threads. In other words, the suspension tower 20 is attached to the side constituent part 16C via the apron upper member 18.

[0035] 1, the partition wall portion 16D is formed in a plate shape extending in the vehicle width direction and the vehicle up-down direction with its plate thickness direction set to the vehicle fore-and-aft direction, and separates the "vehicle interior 12A" from the "power unit room 12B" of the vehicle 12. In addition, the partition wall portion 16D is formed with a "penetration portion 30" that is penetrated in the vehicle fore-and-aft direction and has a rounded rectangular shape with its longitudinal direction set to the vehicle width direction when viewed from the vehicle fore-and-aft direction.

[0036] The through-hole 30 is blocked from the rear of the vehicle by a resin "dash panel component 32" which is a plate-shaped component extending in the width and up and down directions of the vehicle with its thickness direction aligned in the fore-and-aft direction of the vehicle.

[0037] The dash panel component 32 is attached to the partition wall 16D by a mounting member (not shown). That is, in this embodiment, the partition wall 16D and the dash panel component 32 form the main portion of the dash panel 10B of the vehicle body 10. A brake pedal 36, which forms part of a "brake device 34," is attached to the dash panel component 32.

[0038] Meanwhile, a pair of front side members 22 are disposed on the vehicle lower side of the through-hole 30 on the "front surface 16D1" on the vehicle front side of the partition wall 16D. Each of the front side members 22 is an extruded aluminum alloy product, has a rectangular cylindrical shape extending in the vehicle fore-and-aft direction, and is disposed spaced apart from each other in the vehicle width direction. Further, a vehicle rear end 22A of each front side member 22 is attached to the partition wall 16D.

[0039] 5, pop nuts (not shown) are provided on the inner circumferential sides of the front side member 22 at the side wall portion 22A1 on the outer side in the vehicle width direction of the end portion 22A of the front side member 22 and at the lower wall portion 22A2 on the lower side of the vehicle. A mounting plate 38 is attached to the end portion 22A of the front side member 22 using these pop nuts.

[0040] The mounting plate 38 is configured to include a vertical piece 38A that extends in the vertical direction of the vehicle along the side wall portion 22A1 and has a portion that extends above the vehicle further than the front side member 22, a horizontal piece 38B that extends from the peripheral edge of the vertical piece 38A on the lower side of the vehicle toward the inside in the vehicle width direction along the lower wall portion 22A2, and a flange portion 38C that extends from the peripheral edge of the horizontal piece 38B on the inner side in the vehicle width direction toward the bottom of the vehicle.

[0041] Furthermore, through-holes (not shown) are formed in the flange portion 38C and in a portion of the vertical piece portion 38A that is located above the front side member 22. These through-holes are used to attach the front side member 22 to a vehicle body component 16, as will be described later.

[0042] Furthermore, the vertical piece 38A and the horizontal piece 38B have through-holes (not shown) formed therein that correspond to the pop nuts. Fastening members (not shown), such as bolts, are fastened to the pop nuts via these through-holes, thereby attaching the mounting plate 38 to the front side member 22.

[0043] Meanwhile, a mounting portion 16E to which a mounting plate 38 can be attached is provided integrally with the partition portion 16D on a front surface 16D1 of the partition portion 16D. The mounting portion 16E includes a horizontal piece 16E1 extending in the vehicle width direction along an upper wall portion 22A3 on the vehicle upper side of the end portion 22A, a flange portion 16E2 extending upward from a peripheral edge portion of the horizontal piece 16E1 on the outer side in the vehicle width direction toward the vehicle upper side, and a vertical piece 16E3 extending in the vehicle up-down direction along a side wall portion 22A4 on the inner side in the vehicle width direction of the end portion 22A and having a portion extending downward beyond the front side member 22.

[0044] In addition, a through-hole (not shown) is formed in the flange portion 16E2 and the vertical piece portion 16E3 at a portion below the front side member 22 of the vehicle.

[0045] In the mounting plate 38 and mounting portion 16 configured as described above, the through-holes of the vertical piece 38A are fastened to the through-holes of the flange portion 16E2, and the through-holes of the flange portion 38C are fastened to the through-holes of the vertical piece 16E3 with fastening members such as bolts and nuts, etc. In this way, the mounting plate 38 and therefore the front side member 22 are attached to the mounting portion 16E.

[0046] As also shown in FIG. 3, the front side members 22 are located below the suspension towers 20, and the suspension towers 20 are attached to the front side members 22 via attachment members (not shown).

[0047] Although the suspension side rail 24 is partially bent, it is basically configured in the same manner as the front side member 22, and is attached to the vehicle body component 16 on the underside of the front side member 22 in the same manner as the front side member 22.

[0048] On the other hand, on a "back surface 16D2" on the vehicle rear side of the partition wall portion 16D, "lateral rib portions 16F," "lateral rib portions 16G," and "vertical rib portions 16H" are provided as reinforcing ribs protruding from the back surface 16D2 toward the vehicle rear side, as shown in Fig. 4. When viewed from the vehicle front-rear direction, the lateral rib portions 16F, lateral rib portions 16G, and vertical rib portions 16H extend from the front side members 22.

[0049] Specifically, the lateral rib portions 16F are located on the outer sides of the front side members 22 in the vehicle width direction, extend in the vehicle width direction, and are arranged at intervals in the vehicle up-down direction.

[0050] The lateral rib portions 16G are located between the pair of front side members 22 and extend in the vehicle width direction, with a plurality of lateral rib portions 16G being arranged at intervals in the vehicle up-down direction.

[0051] The vertical rib portions 16H are located below the front side members 22 and extend in the vehicle vertical direction, with a plurality of them being arranged at intervals in the vehicle width direction.

[0052] (Actions and Effects of This Embodiment) Next, the operation and effects of this embodiment will be described.

[0053] In this embodiment, as shown in Figures 1 and 2, the vehicle body 10 is provided with a vehicle body component 16 having an upper component 16A extending in the vehicle width direction, a lower component 16B extending in the vehicle width direction, a pair of side component parts 16C connecting the upper component part 16A and the lower component part 16B, and a partition part 16D integrated with the upper component part 16A, the lower component part 16B, and the side component part 16C.

[0054] Meanwhile, the shapes of the windshield glass 29 tend to be similar in vehicles 12 of various specifications, and the shapes of the portions of the vehicle body 10 that support the windshield glass 29 also tend to be similar. Furthermore, although the height of the floor portion of the vehicle body 10 tends to differ among vehicles 12 of various specifications, the correlation between the floor portion of the vehicle body 10 and the portions that support it tends to be similar. Furthermore, although the overall configuration of the front pillar 10A tends to differ among vehicles 12 of various specifications, the configuration of the portion below the front pillar 10A tends to be similar among vehicles 12 of various specifications. Furthermore, the configuration of the partition wall that separates the passenger compartment 12A and the power unit compartment 12B tends to be similar among vehicles 12 of various specifications.

[0055] In this embodiment, the upper constituent portion 16A is capable of supporting a windshield glass 29, the lower constituent portion 16B is disposed along the front edge of the floor portion and is capable of supporting the floor portion, the side constituent portion 16C forms part of the vehicle underside of the front pillar 10A, and the partition portion 16D separates the passenger compartment 12A from the power unit room 12B. In addition, the side constituent portion 16C is capable of mounting a suspension tower 20 that can support part of a suspension, the mounting position of which tends to vary depending on the specifications of the vehicle 12, etc.

[0056] That is, in this embodiment, the parts of the vehicle body 10 that can be made common among vehicles 12 of various specifications are integrated into the vehicle body component 16. In addition, the parts of the vehicle body 10 that are difficult to make common among vehicles 12 of various specifications are attached to the vehicle body component 16 as separate parts.

[0057] In this embodiment, the vehicle body component 16 is a metal casting, and the upper component 16A, the lower component 16B, the side component 16C, and the partition wall 16D can be configured as a single component. This allows for a reduction in the number of components that make up the vehicle body component 16, compared to a configuration in which the vehicle body component 16 is configured by welding these components together using steel plates or the like.

[0058] 4, in this embodiment, a through-hole 30 is formed in the partition wall 16D, penetrating the partition wall 16D in the longitudinal direction of the vehicle, and the through-hole 30 is closed by a dash panel component 32. A part of a brake device 34 is attached to the dash panel component 32.

[0059] Therefore, in this embodiment, by attaching a dash panel component 32 having an attachment point corresponding to the attachment position of the brake device 34 to the partition portion 16D according to the specifications of the vehicle 12, it is possible to attach a portion of the brake device 34 to the body component 16 without changing the shape of the body component 16.

[0060] In addition, in this embodiment, since the dash panel component 32 is made of resin, by adjusting the resin molding die used to manufacture the dash panel component 32, it is possible to accommodate changes in the mounting position of the brake device 34 on the vehicle 12.

[0061] 1, the present embodiment includes a front side member 22 that extends in the vehicle longitudinal direction and is attached to a front surface 16D1 of the partition wall portion 16D at the front of the vehicle, and this front side member 22 forms part of the frame of the vehicle front side of the vehicle body 10. The front side member 22 is also located below the suspension tower 20, and can support the suspension tower 20.

[0062] Incidentally, it is conceivable that vibrations from the suspension side are input to the partition wall portion 16D via the suspension tower 20 and the front side member 22, causing vibrations in the partition wall portion 16D.

[0063] 4, in this embodiment, lateral rib portions 16F, lateral rib portions 16G, and vertical rib portions 16H are formed on a back surface 16D2 of the partition wall portion 16D on the vehicle rear side. The lateral rib portions 16F, lateral rib portions 16G, and vertical rib portions 16H protrude toward the vehicle rear from the back surface 16D2 of the partition wall portion 16D and extend from the front side member 22 when viewed from the vehicle longitudinal direction. Therefore, in this embodiment, the lateral rib portions 16F, lateral rib portions 16G, and vertical rib portions 16H ensure the rigidity of the partition wall portion 16D against various vibrations and can suppress vibration of the partition wall portion 16D due to vibrations from the suspension side.

[0064] As described above, according to the vehicle body 10 of this embodiment, the number of parts constituting the vehicle body 10 can be reduced, and the parts constituting the vehicle body 10 can be standardized. [Explanation of symbols]
