[0002] As described in Japanese Patent Application Laid-Open No. 2005-53431, there is known a technique in which a rear frame of a vehicle, which is a portion of a vehicle skeleton structure located around rear wheels, is constructed from a plurality of sheet metal members. Summary of the Invention

[0003] However, the technology disclosed in the above publication may increase the number of parts constituting the rear frame, thereby possibly increasing the burden of assembly work and the weight of the rear frame.

[0004] In one aspect of the present disclosure, it is desired to promote a reduction in the burden of assembly work and to promote weight reduction.

[0005] One embodiment of the present disclosure is a bracket installed in a vehicle, the bracket comprising: a bottom portion, a bottom joint, a side wall portion, an upper joint, and an inner rib portion. The bottom portion is configured to be opposite to a suspension component. The bottom joint portion is provided on the bottom portion and is configured to join the suspension component to the bottom portion. The side wall portion is a wall-shaped portion protruding upward from the edge of the bottom portion, and the side wall portion is provided to surround the edge of the bottom portion. The upper joint portion is provided at the upper end of the side wall portion and is configured to join to a component constituting a part of the vehicle's skeleton structure. The inner rib portion is a wall-shaped portion protruding upward from the bottom portion. The bracket is an integrally formed component made of aluminum or an aluminum alloy.

[0006] The above configuration reduces the number of components and improves the rigidity of the bracket. Furthermore, by integrally molding the bracket from aluminum or an aluminum alloy, it can be lightweight. This reduces the burden of assembly work and promotes lightweighting.

[0007] In one aspect of the present disclosure, the inner rib portion may extend from the side wall portion to the bottom surface joint portion.

[0008] According to the above configuration, the rigidity of the bracket can be improved.

[0009] In one aspect of the present disclosure, the bracket may further include an outer rib portion, which is a wall-shaped portion protruding from the outer peripheral surface of the side wall portion, and the outer rib portion extends in a direction substantially coinciding with the up-down direction.

[0010] According to the above configuration, the rigidity of the bracket can be improved.

[0011] In one aspect of the present disclosure, the lower end of the outer rib portion may be located above the bottom portion.

[0012] According to the above configuration, the weight reduction of the bracket can be promoted.

[0013] In one embodiment of the present disclosure, the bottom portion may be a substantially rectangular plate-shaped portion. In addition, the side wall portion may have four planarly extended portions, which protrude from portions of the bottom portion forming the sides.

[0014] According to the above configuration, it is possible to promote improvement in the rigidity of the bracket.

[0015] In one embodiment of the present disclosure, the upper engaging portion may be a flange-shaped portion provided at the upper ends of the four planarly extended portions of the side wall portion.

[0016] According to the above configuration, the bracket can be satisfactorily joined to a member constituting a portion of the vehicle frame structure.

[0017] In one embodiment of the present disclosure, the upper joining portion may include a first upper joining portion and a second upper joining portion. The second upper joining portion is located lateral to the first upper joining portion. The first upper joining portion may be configured to join with a first component included in the vehicle's skeletal structure. The second upper joining portion may be configured to join with a second component included in the vehicle's skeletal structure, where the second component is different from the first component.

[0018] According to the above configuration, even when the bracket is joined to a plurality of components, it is possible to reduce the burden of assembly work and to promote weight reduction.

[0019] In one aspect of the present disclosure, the side wall portion may include a long side portion that is a portion extending in a planar shape from an edge portion of the bottom surface portion to the first upper joining portion and the second upper joining portion.

[0020] According to the above configuration, the rigidity of the bracket can be improved.

[0021] In one embodiment of the present disclosure, the bottom portion may be a substantially rectangular plate-shaped portion. The side wall portion may have two long sides, each of which extends longitudinally from an edge of the bottom portion, and the two portions forming the long sides extend in a planar shape to the first upper joint portion and the second upper joint portion.

[0022] According to the above configuration, the rigidity of the bracket can be improved.

[0023] In one embodiment of the present disclosure, the second upper joining portion may be located above the first upper joining portion. Each of the two long sides may include a first portion that is generally rectangular and a second portion that is generally triangular, wherein the first portion is located above the bottom portion and the second portion is located to the side of the first portion. The width of the second portion may increase as it approaches the upper portion. The first upper joining portion may be provided at the upper end of the first portion, and the second upper joining portion may be provided at the upper end of the second portion.

[0024] According to the above configuration, the bracket can be improved in rigidity while being satisfactorily joined to a member constituting a portion of the vehicle frame structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0038] [1. First embodiment]

[0039] [(1) Summary]

[0040] The bracket 1 of the first embodiment is mounted on the right side and left side members of the vehicle and is used to connect the suspension member 5, the floor member 6, and the side member 7 of the vehicle to each other (see Figures 1 to 6 The suspension member 5 is one of the structural members that form part of the vehicle's frame structure and is located around the suspension system for the vehicle's rear wheels. Furthermore, the floor member 6 is a plate-shaped structural member located at the bottom of the interior space of the vehicle, such as the passenger compartment, while the side members 7 are frame-shaped structural members located on the left and right sides of the vehicle and extend in the front-to-rear direction.

[0041] The bracket 1 is made of aluminum or aluminum alloy and is integrally formed by aluminum die-casting process. Of course, but not limited to this, the bracket 1 can also be integrally formed by other casting methods, for example, a casting method using semi-solid aluminum.

[0042] Bracket 1 includes a bottom portion 2, sidewalls 3, and an upper joint 4. Bracket 1 has an elongated shape. As an example, bracket 1 is mounted on a vehicle such that its longitudinal direction generally aligns with the vehicle's left-right direction, and its lateral direction generally aligns with the vehicle's front-back direction. In the following description, the center and end sides of the vehicle in the left-right direction are referred to as the inner side and outer side, respectively. This is not limiting; the orientation of bracket 1 when mounted on the vehicle can be appropriately determined as needed.

[0043] [(2) Bottom part]

[0044] As an example, the bottom portion 2 is a substantially rectangular plate-shaped portion that extends along the longitudinal direction of the bracket 1 and is arranged to face the suspension member 5 (see FIG. Figures 1 to 6 Of course, the shape of the bottom portion 2 is not limited to a rectangle and can be appropriately set as needed. The bottom portion 2 includes a bottom surface joint 20, a first inner rib 21, and a second inner rib 22.

[0045] <Bottom Joint>

[0046] The bottom surface joint 20 is a portion for joining the suspension member 5 to the bottom surface portion 2 (see Figure 1 、 Figure 3 and Figure 4 The bottom joint 20 is a cylindrical portion located approximately in the center of the bottom portion 2 and protrudes upward. The top of the bottom joint 20 is closed. The bottom joint 20 forms a circular hole approximately in the center of the bottom portion 2 (see Figure 4), a thread is provided on the inner peripheral surface of the bottom surface joint portion 20. Furthermore, by inserting the bolt 10 into the bottom surface joint portion 20 from the lower surface side of the bottom surface portion 2, the bottom surface portion 2 and the suspension member 5 are joined to each other.

[0047] The bottom surface joint portion 20 is not limited thereto, and may be configured as, for example, a bolt hole formed in the bottom surface portion 2. Even in this case, the bottom surface portion 2 and the suspension member 5 can be joined together by the bolts 10 and nuts inserted into the bottom surface joint portion 20. Furthermore, the bottom surface joint portion 20 may be configured so that the bottom surface portion 2 and the suspension member 5 are joined together by means other than bolts.

[0048] <1st Inner Rib and 2nd Inner Rib>

[0049] The first inner rib 21 and the second inner rib 22 are wall-shaped portions that are located inside the side wall portion 3 described later and protrude upward from the bottom portion 2. The first inner rib 21 and the second inner rib 22 extend linearly along the longitudinal direction and the transverse direction of the bracket 1, respectively (see FIG. Figure 3 As an example, the heights of the first inner rib 21 and the second inner rib 22 from the bottom surface 2 to the top are substantially constant.

[0050] The first inner rib 21 extends in a generally planar shape along the longitudinal direction, and its ends in the longitudinal direction are connected to the first short side 31 and the second short side 32 of the side wall 3 described later. In addition, the second inner rib 22 extends in a generally planar shape along the transverse direction, and its ends in the transverse direction are connected to the respective long sides 30 of the side wall 3 described later.

[0051] Furthermore, the bottom joint portion 20 is located approximately at the center of the first inner rib 21 in the longitudinal direction and approximately at the center of the second inner rib 22 in the transverse direction. In other words, the first inner rib 21 and the second inner rib 22 extend so as to intersect at the bottom joint portion 20. In other words, the first inner rib 21 and the second inner rib 22 each extend from the side wall portion 3 to the bottom joint portion 20. More specifically, the first inner rib 21 and the second inner rib 22 each have wall-like portions located on both sides of the bottom joint portion 20, which are connected to the bottom joint portion 20.

[0052] The position, number, and shape of the inner ribs provided on the bottom portion 2 are not limited thereto and may be appropriately determined as needed. Specifically, for example, only one of the first inner rib 21 and the second inner rib 22 may be provided on the bottom portion 2, or neither the first inner rib 21 nor the second inner rib 22 may be provided. Furthermore, for example, if the bottom surface joint 20 is configured as a bolt hole formed in the bottom portion 2, the inner rib may extend to the edge of the bolt hole.

[0053] [(3) Side wall]

[0054] The side wall portion 3 is a wall-shaped portion that protrudes upward from the edge of the bottom portion 2, and is provided so as to surround the edge of the bottom portion 2 (see Figures 1 to 6 The side wall portion 3 includes two long sides 30, a first short side 31, and a second short side 32, and first to third outer ribs 33 to 35 provided on each of the long sides 30. Furthermore, the side wall portion 3 forms an opening 36 on the side opposite to the bottom portion 2. The opening 36 is surrounded by the upper ends of the two long sides 30 and the upper ends of the first and second short sides 31 and 32.

[0055] <Long side>

[0056] The long sides 30 are formed from the edges of the substantially rectangular bottom surface 2 to form the sides extending in the longitudinal direction, and are opposed to each other in the transverse direction (see FIG. Figures 1 to 4 More specifically, each long side 30 is inclined relative to the vertical direction so that the spacing between the long sides 30 increases as the distance from the bottom surface portion 2 increases. In addition, each long side 30 is connected to the first to third intermediate portions 41 to 43 of the upper joint portion 4 described later and expands in a planar shape.

[0057] Each long side 30 has a generally rectangular first portion 30A and a generally triangular second portion 30B. The first portion 30A is located above the bottom portion 2, and the second portion 30B is located inside the first portion 30A. The second portion 30B is arranged so that its width increases as it approaches the top, with the end of the second portion 30B that forms the boundary with the second short side 32 forming one side of the triangle and extending straightly upward from the inside end of the bottom portion 2.

[0058] <First Short Side and Second Short Side>

[0059] The first short side 31 and the second short side 32 are respectively formed from the edge of the substantially rectangular bottom portion 2, forming a side portion extending in the horizontal direction, and are extended in a planar shape, and are opposed to each other in the longitudinal direction (refer to FIG. Figures 1 to 6More specifically, the first short side 31 and the second short side 32 are located on the outside and inside, respectively, and are connected to the outside end of the first portion 30A and the inside end of the second portion 30B of the long side 30. The first short side 31 and the second short side 32 are inclined relative to the vertical direction so that the distance between them increases as they move away from the bottom portion 2. Furthermore, the second short side 32 has a greater inclination relative to the vertical direction than the first short side 31.

[0060] <1st to 3rd outer ribs>

[0061] The first to third outer ribs 33 to 35 are wall-shaped portions protruding from the outer peripheral surface of the first portion 30A of each long side portion 30, extending in a direction substantially aligned with the vertical direction, and arranged at substantially constant intervals from the outside toward the inside (in other words, along the longitudinal direction) (see FIG. Figure 1 、 Figure 2 、 Figures 4 to 6 ). In addition, the first outer rib 33 is located at the outer end of the first portion 30A, the second outer rib 34 is located at the approximate center of the first portion 30A in the longitudinal direction, and the third outer rib 35 is located at the inner end of the first portion 30A.

[0062] The first to third outer ribs 33 to 35 of each long side portion 30 have the same structure. That is, each of the first to third outer ribs 33 to 35 is triangular in shape, and its upper end is connected to the first middle portion 41 of the upper joint portion 4 described later. In addition, the top of the first to third outer ribs 33 to 35 constitutes one side of the triangle, and the height between the long side portion 30 and the top decreases as it approaches the bottom portion 2. In addition, the upper end of the top is located at the end of the first middle portion 41. In addition, the lower end of the top constitutes the lower end of the outer rib and is located near the bottom portion 2 in the long side portion 30 and above the bottom portion 2.

[0063] Furthermore, the first outer rib 33, the first short side 31, and the outer side 40 of the upper joint 4 described later, which are located on the outermost side, are extended to form substantially the same plane. Furthermore, the third outer rib 35, the innermost side, and the second middle portion 42 of the upper joint 4 described later, are extended to form substantially the same plane.

[0064] Of course, the position, number, and shape of the outer ribs provided on each long side 30 are not limited thereto and may be appropriately determined according to circumstances. Furthermore, in addition to or in place of the first portion 30A, an outer rib may be provided on the second portion 30B of each long side 30, or the outer rib may not be provided on each long side 30.

[0065] [(4) Upper side joint]

[0066] The upper side joint portion 4 is a flange-shaped portion provided at the upper end of the side wall portion 3, and is joined to the floor member 6 and the side member 7 (see FIG. Figures 1 to 6 The upper joint portion 4 includes an outer portion 40, two first intermediate portions 41, two second intermediate portions 42, two third intermediate portions 43, and an inner portion 44, which are connected to each other around the opening 36 of the side wall portion 3. Of course, the structure of the upper joint portion 4 is only an example, and the shape of the upper joint portion 4 can be appropriately set according to the shape of the skeleton structure member to which the bracket 1 is connected.

[0067] <Outer side>

[0068] The outer portion 40 is located at the outer end of the bracket 1 in the longitudinal direction (see Figures 1 to 4 、 Figure 6 The outer portion 40 is located at the upper end of the first short side portion 31 and is inclined relative to the vertical direction similarly to the first short side portion 31 .

[0069] <1st middle section to 3rd middle section>

[0070] The two first intermediate portions 41 are respectively located at the upper ends of the first portion 30A of the long side portion 30 and extend inward from both ends of the outer portion 40 along the longitudinal direction. The two first intermediate portions 41 are opposite to each other in the transverse direction (see FIG. Figures 1 to 6 ) In addition, the length of each first intermediate portion 41 in the longitudinal direction is equivalent to the length of the bottom portion 2 in the longitudinal direction.

[0071] The two second intermediate portions 42 are located at the outer ends of the second portion 30B of the long side 30 and extend upward from the inner ends of the corresponding first intermediate portions 41. As an example, each second intermediate portion 42 is inclined relative to the vertical direction so as to move inward as it moves away from the first intermediate portion 41. Furthermore, the two second intermediate portions 42 face each other in the transverse direction and face the outer portion 40 in the longitudinal direction.

[0072] The two third intermediate portions 43 are located at the upper ends of the second portions 30B of the long sides 30 and extend inwardly along the longitudinal direction from the upper ends of the corresponding second intermediate portions 42. The two third intermediate portions 43 are opposed to each other in the transverse direction. Furthermore, the two third intermediate portions 43 are located above and to the sides of the two first intermediate portions 41 and the outer portion 40.

[0073] <Inside>

[0074] The inner portion 44 is located at the inner end of the bracket 1 in the longitudinal direction (see Figures 1 to 6 The inner portion 44 is located at the upper end of the second short side portion 32 , and the inner portion 44 and each third intermediate portion 43 extend to form a substantially identical plane.

[0075] <Joining of the Upper Joint>

[0076] The upper joint portion 4 is joined to the side member 7 and the floor member 6 by adhesive and mechanical joining means. In addition, the mechanical joining means may be, for example, a joining method using bolts, friction welding, or riveting. In addition, as an example, the outer portion 40, each first intermediate portion 41, and each second intermediate portion 42 constitute the first upper joint portion joined to the side member 7, and each third intermediate portion 43 and the inner portion 44 constitute the second upper joint portion joined to the floor member 6 (see Figure 1 ).

[0077] Specifically, an adhesive is applied to the outer portion 40, each first intermediate portion 41, each second intermediate portion 42, each third intermediate portion 43, and the inner portion 44, and the above-mentioned portions are joined to the side member 7 and the floor member 6 by the adhesive. In addition, a plurality of joints 4A are provided on each first intermediate portion 41, each second intermediate portion 42, each third intermediate portion 43, and the inner portion 44 (see FIG. Figure 3 ) Furthermore, the joint portion 4A is joined to the side member 7 or the floor member 6 by mechanical joining means after being joined by an adhesive.

[0078] Of course, the present invention is not limited thereto, and the upper joint portion 4 may be joined to the side member 7 and the floor member 6 by, for example, an adhesive or a mechanical joining means.

[0079] Furthermore, the portion of the side member 7 and the floor member 6 that is joined to the upper joint 4 can be made of iron. More specifically, the portion can be made of, for example, high-tensile-strength steel having a tensile strength of 590 MPa or greater, or even ultra-high-tensile-strength steel having a tensile strength of 1470 MPa or greater.

[0080] [2. Second embodiment]

[0081] [(1) Summary]

[0082] The bracket 1 of the second embodiment has the same structure as the first embodiment, but is different from the first embodiment in that the suspension member 5 and the side member 7 are joined to each other (see FIG. Figures 7 to 12 ) In addition, the bracket 1 of the second embodiment may be configured such that the suspension member 5 and a skeleton structure member other than the side member 7 are joined to each other.

[0083] That is, compared to the first embodiment, the bracket 1 of the second embodiment is shorter in the left-right direction, in other words, shorter in the longitudinal direction, and differs from the first embodiment in the structure of the side wall portion 3 and the upper side joint portion 4. The differences between the bracket 1 of the second embodiment and the first embodiment are described below.

[0084] [(2) Side wall]

[0085] The side wall portion 3 of the second embodiment includes two long sides 30, a first short side 31 and a second short side 32. The difference from the first embodiment lies in the structure of each long side 30 and the second short side 32 (see FIG. Figures 7 to 12 ).

[0086] That is, the long side 30 of the second embodiment does not have the second portion 30B of the long side 30 of the first embodiment, but is composed of a portion corresponding to the first portion 30A. In other words, the long side 30 of the second embodiment has a substantially rectangular shape, extends in the left-right direction, and is located on the upper side of the bottom portion 2.

[0087] Furthermore, the second short side portion 32 is connected to the inner end of each long side portion 30 and faces the first short side portion 31. The inclination of the second short side portion 32 with respect to the vertical direction is equivalent to the inclination of the first short side portion 31 with respect to the vertical direction, and the second short side portion 32 moves away from the first short side portion 31 as it goes upward.

[0088] The configuration of the first to third outer ribs 33 to 35 is the same as that of the first embodiment. The first outer rib 33 is located at the outer end of the long side 30, the second outer rib 34 is located approximately in the center of the long side 30 in the longitudinal direction, and the third outer rib 35 is located at the inner end of the long side 30.

[0089] [(3) Upper side joint]

[0090] The upper joint portion 4 of the second embodiment includes an outer portion 40, two intermediate portions 45, and an inner portion 46, which are connected to each other to form a flange-shaped portion and surround the opening 36 of the side wall portion 3 (see Figures 7 to 12 ).

[0091] The outer portion 40 is located at the outer end of the stent 1 and has the same configuration as that of the first embodiment.

[0092] The two intermediate portions 45 are located at the upper ends of the long sides 30. The two intermediate portions 45 extend inwardly along the longitudinal direction from both ends of the outer portion 40 to the inner portion 46, and the two intermediate portions 45 face each other in the front-to-back direction. The length of each intermediate portion 45 in the left-right direction is equivalent to the length of the bottom portion 2 in the left-to-right direction.

[0093] The inner portion 46 is located at the inner end of the bracket 1 and extends to connect the inner ends of each intermediate portion 45. The inner portion 46 is located at the upper end of the second short side 32 and faces the outer portion 40 in the left-right direction. Furthermore, the inner portion 46, the second short side 32, and the third outer rib 35 of each long side 30 extend to form a substantially identical plane.

[0094] [(4) Joining of upper joining portion]

[0095] As in the first embodiment, the upper joint portion 4 is joined to the side member 7 by adhesive and mechanical joining means (see Figure 7 Specifically, an adhesive is applied to the outer portion 40, each intermediate portion 45, and the inner portion 46, and the above-mentioned portions are bonded to the side member 7 by the adhesive. In addition, a plurality of bonding portions 4A are provided on each intermediate portion 45 (see Figure 9 ). Thereafter, the above-mentioned joint portion 4A is joined to the side member 7 by mechanical joining means. Of course, similarly to the first embodiment, the upper joint portion 4 can be joined to the side member 7 by, for example, an adhesive or mechanical joining means.

[0096] [3. Effect]

[0097] According to the embodiments described above, the following effects can be obtained.

[0098] (1) According to the above embodiment, the bracket 1 is integrally formed by aluminum die-casting, thereby reducing the number of components, improving rigidity, and promoting weight reduction. Furthermore, since the first inner rib 21 and the second inner rib 22 are provided on the inner side of the side wall 3 and protrude from the bottom surface 2, the rigidity of the bracket 1 is improved. This reduces the burden of assembly work and promotes weight reduction.

[0099] In addition, by increasing the rigidity of the bracket 1 , the driving safety and riding comfort of the vehicle can also be improved.

[0100] Furthermore, the above embodiment can be viewed as applying integral aluminum die-casting to a portion of the bracket 1, which corresponds to a portion of the frame structure, rather than to a frame structure component such as the suspension component 5. Therefore, compared to forming the entire frame structure component using aluminum die-casting, the structure of the conventional frame structure component can be more reliably utilized, thereby reducing costs and enabling the bracket 1 to be applied to a variety of vehicle models.

[0101] (2) Furthermore, since the first inner rib 21 and the second inner rib 22 extend from the side wall portion 3 to the bottom surface joint portion 20, the rigidity of the bracket 1 can be improved. Furthermore, the first inner rib 21 and the second inner rib 22 extend linearly in the left-right direction (in other words, the longitudinal direction) and the front-back direction (in other words, the transverse direction) of the vehicle, respectively. Therefore, the rigidity of the bracket 1 when subjected to loads in the left-right direction and the front-back direction of the vehicle is improved.

[0102] (3) Furthermore, the first to third outer ribs 33 to 35 are provided on each of the long sides 30. Therefore, the rigidity of the bracket 1 can be improved.

[0103] (4) Furthermore, a distance is provided between the lower ends of the first to third outer ribs 33 to 35 and the bottom surface portion 2. Therefore, it is possible to suppress a decrease in rigidity while promoting weight reduction of the bracket 1.

[0104] (5) Furthermore, the bracket 1 of the first embodiment is joined to the side member 7 via the outer portion 40, each first intermediate portion 41, and each second intermediate portion 42, and is joined to the floor member 6 via each third intermediate portion 43 and the inner portion 44. Therefore, even when the bracket 1 is joined to a plurality of components, it is possible to reduce the burden of assembly work and promote weight reduction.

[0105] (6) Furthermore, each long side 30 of the bracket 1 of the first embodiment extends in a planar shape from the edge portion of the bottom portion 2 extending in the longitudinal direction to the first to third intermediate portions 41 to 43. Therefore, the rigidity of the bracket 1 when subjected to a load in the left-right direction of the vehicle (in other words, the longitudinal direction) can be increased.

[0106] [4. Other Implementation Methods]

[0107] (1) The bracket 1 of the first embodiment may be joined to two other skeletal components other than the floor member 6 and the side member 7, may be joined to the floor member 6 and another skeletal component, or may be joined to the side member 7 and another skeletal component. Furthermore, the bracket 1 of the second embodiment may be joined to other skeletal components other than the side member 7. Furthermore, the bracket 1 of the first embodiment may be configured so that the suspension member 5 is joined to three or more skeletal components.

[0108] (2) The bracket 1 of the first and second embodiments may be configured such that a suspension member provided around a vehicle front wheel suspension member is joined to at least one framework member.

[0109] (3) The multiple functions of one component in the above-mentioned embodiment may be realized by multiple components, or the one function of one component may be realized by multiple components. In addition, the multiple functions of multiple components may be realized by one component, or the one function of multiple components may be realized by one component. In addition, part of the structure of the above-mentioned embodiment may be omitted.
