Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the technique disclosed in Patent Document 1, the number of parts constituting the rear frame may increase, which may increase the load of the assembly work or increase the weight of the rear frame.

[0005] In one aspect of the present disclosure, it is desirable to reduce the load of the assembly work and promote weight reduction.

Means for Solving the Problems

[0006] One aspect of the present disclosure is a bracket mounted on a vehicle, comprising a bottom portion, a bottom joint portion, a side wall portion, an upper joint portion, and an inner rib. The bottom portion is configured to face a suspension member. The bottom joint portion is provided on the bottom portion and is configured to connect the suspension member to the bottom portion. The side wall portion is a wall-like portion that protrudes upward from the edge of the bottom portion and is provided so as to encircle 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 connect to a member that constitutes part of the vehicle's skeletal structure. The inner rib is a wall-like portion that protrudes upward from the bottom portion. The bracket is made of aluminum or an aluminum alloy and is a integrally molded member.

[0007] The above configuration allows for a reduction in the number of parts and promotes improved bracket rigidity. Furthermore, by integrally molding the bracket from aluminum or an aluminum alloy, weight reduction is possible. Therefore, the burden of assembly work is reduced, and weight reduction is promoted.

[0008] In one aspect of this disclosure, the inner rib may extend from the side wall to the bottom joint. The above configuration allows for improved rigidity of the bracket. One aspect of the present disclosure may further include an outer rib, which is a wall-like portion protruding from the outer circumferential surface of the side wall portion and extending in a direction substantially coinciding with the vertical direction.

[0009] The above configuration allows for improved rigidity of the bracket. In one aspect of this disclosure, the lower end of the outer rib may be located above the bottom surface. The above configuration makes it possible to reduce the weight of the bracket.

[0010] In one aspect of this disclosure, the upper joint may have a first upper joint and a second upper joint. The second upper joint is located laterally to the first upper joint. The first upper joint may be configured to join to a first member included in the vehicle's skeletal structure. The second upper joint may be configured to join to a second member, which is a member included in the vehicle's skeletal structure and is different from the first member.

[0011] According to the above configuration, even when the bracket is joined to multiple components, it is possible to reduce the workload during assembly and to reduce weight. In one aspect of the present disclosure, the side wall portion may have a longitudinal portion which is a planar portion extending from the edge of the bottom portion to the first and second upper joint portions.

[0012] The above configuration allows for improved rigidity of the bracket. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0014] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings. [1. First Embodiment] [(1) Overview] The bracket 1 of the first embodiment is mounted on the right and left portions of the vehicle and is used to join the suspension member 5 of the vehicle, the floor member 6, and the side member 7 (see FIGS. 1 to 6). The suspension member 5 is one of the skeletal structure members constituting a part of the skeletal structure of the vehicle and is provided around the suspension of the rear wheels of the vehicle. The floor member 6 is a plate-shaped skeletal structure member located at the bottom of the space inside the vehicle such as the passenger compartment, and the side member 7 is a frame-shaped skeletal structure member located on the right and left sides of the vehicle and extending in the front-rear direction.

[0015] The bracket 1 is made of aluminum or an aluminum alloy and is integrally formed by aluminum die casting. Of course, it is not limited to this, and the bracket 1 may be integrally formed by other casting methods, for example, a casting method using semi-solid aluminum.

[0016] The bracket 1 includes a bottom surface portion 2, a side wall portion 3, and an upper joining portion 4. The bracket 1 has an elongated shape. As an example, it is mounted on the vehicle such that the longitudinal direction substantially coincides with the left-right direction of the vehicle and the short-side direction substantially coincides with the front-rear direction of the vehicle. In the following description, the central side and the end side of the vehicle in the left-right direction are simply described as the inner side and the outer side, respectively. Also, it is not limited to this, and the orientation of the bracket 1 when mounted on the vehicle can be appropriately determined.

[0017] [(2) Bottom Surface Portion] The bottom portion 2 is, for example, a roughly rectangular plate-like portion extending in the longitudinal direction of the bracket 1, and is positioned to face the suspension member 5 (see Figures 1-6). Of course, the shape of the bottom portion 2 is not limited to a rectangle and can be determined as appropriate. The bottom portion 2 comprises a bottom joint portion 20 and first and second inner ribs 21 and 22.

[0018] <Bottom joint> The bottom joint portion 20 is the part for joining the suspension member 5 to the bottom portion 2 (see Figures 1, 3, and 4). The bottom joint portion 20 is located approximately in the center of the bottom portion 2 and is a cylindrical part that protrudes upward, with its top closed by a wall. The bottom joint portion 20 has a circular hole formed approximately in the center of the bottom portion 2 (see Figure 4), and a screw thread is provided on the inner circumferential surface of the bottom joint portion 20. The bottom portion 2 and the suspension member 5 are joined by inserting a bolt 10 into the bottom joint portion 20 from the lower side of the bottom portion 2.

[0019] However, the bottom joint portion 20 is not limited to this, and may be configured, for example, as a bolt hole formed in the bottom portion 2. Even in such a case, the bottom portion 2 and the suspension member 5 can be joined by a bolt 10 and nut inserted into the bottom joint portion 20. Alternatively, the bottom joint portion 20 may be configured to join the bottom portion 2 and the suspension member 5 by means other than bolts.

[0020] <First and second inner ribs> The first and second inner ribs 21 and 22 are located inside the side wall portion 3, which will be described later, and are wall-like portions that protrude upward from the bottom surface portion 2. The first and second inner ribs 21 and 22 extend linearly along the longitudinal and transverse directions of the bracket 1, respectively (see Figure 3). As an example, the height of the first and second inner ribs 21 and 22 from the bottom surface portion 2 to the top is approximately constant.

[0021] The first inner rib 21 extends in a substantially planar shape along its longitudinal direction, and both ends in the longitudinal direction connect to the first and second short sections 31 and 32 of the side wall section 3, which will be described later. The second inner rib 22 extends in a substantially planar shape along its short direction, and both ends in the short direction connect to the respective longitudinal sections 30 of the side wall section 3, which will be described later.

[0022] Furthermore, the bottom joint 20 is located approximately in the center of the longitudinal direction of the first inner rib 21 and approximately in the center of the short direction of the second inner rib 22. In other words, the first and second inner ribs 21 and 22 extend outward so as to intersect at the bottom joint 20. That is, the first and second inner ribs 21 and 22 each extend from the side wall portion 3 to the bottom joint 20. More specifically, the first and second inner ribs 21 and 22 each have wall-like portions located on both sides of the bottom joint 20, and these portions are connected to the bottom joint 20.

[0023] The position, number, and shape of the inner ribs provided on the bottom surface 2 are not limited to those shown and can be determined as appropriate. Specifically, for example, the bottom surface 2 may be provided with only one of the first and second inner ribs 21, 22, or it may not be provided with either the first and second inner ribs 21, 22. Also, for example, if the bottom surface joint 20 is configured as a bolt hole formed in the bottom surface 2, the inner ribs may extend to the edge of the bolt hole.

[0024] [(3) Side wall section] The side wall portion 3 is a wall-like portion that protrudes upward from the edge of the bottom portion 2 and is provided so as to encircle the edge of the bottom portion 2 (see Figures 1 to 6). The side wall portion 3 comprises two longitudinal portions 30, first and second short portions 31 and 32, and first to third outer ribs 33 to 35 provided on each longitudinal portion 30. The side wall portion 3 also forms an opening 36 on the opposite side of the bottom portion 2, surrounded by the upper ends of the two longitudinal portions 30 and the upper ends of the first and second short portions 31 and 32.

[0025] <Longitudinal part> Each longitudinal section 30 protrudes from each edge extending in the longitudinal direction of the base section 2 and faces each other in the short direction (see Figures 1-4). More specifically, each longitudinal section 30 is inclined in the vertical direction such that the distance between each longitudinal section 30 increases as it moves away from the base section 2. In addition, each longitudinal section 30 is connected to the first to third intermediate sections 41-43 of the upper joint section 4, which will be described later, and spreads out in a planar manner.

[0026] Furthermore, each longitudinal portion 30 has a rectangular first portion 30A and a triangular second portion 30B. The first portion 30A is located on the upper side of the base portion 2, and the second portion 30B is located inside the first portion 30A. The second portion 30B is arranged to become wider towards the top, and the end of the second portion 30B that forms the boundary with the second transverse portion 32 forms one side of a triangle and extends linearly diagonally upward from the inner end of the base portion 2.

[0027] <First and Second Short Sections> The first and second short portions 31 and 32 protrude from the edges extending in the short direction of the base portion 2, spreading out in a planar manner and facing each other in the longitudinal direction (see Figures 1-6). More specifically, the first and second short portions 31 and 32 are located on the outside and inside, respectively, and connect to the outer end of the first portion 30A and the inner end of the second portion 30B of the longitudinal portion 30. The first and second short portions 31 and 32 are inclined in the vertical direction such that the distance between them increases as they move away from the base portion 2. Furthermore, the second short portion 32 has a greater degree of inclination in the vertical direction compared to the first short portion 31.

[0028] <1st to 3rd outer ribs> The first to third outer ribs 33 to 35 are wall-like portions that protrude from the outer circumferential surface of the first portion 30A in each longitudinal section 30, extending in a direction approximately coinciding with the vertical direction, and arranged at approximately constant intervals from the outside to the inside (in other words, along the longitudinal direction) (see Figures 1, 2, 4 to 6). The first outer rib 33 is located at the outer end of the first portion 30A, the second outer rib 34 is located approximately in the center of the longitudinal direction of the first portion 30A, and the third outer rib 35 is located at the inner end of the first portion 30A.

[0029] The first to third outer ribs 33 to 35 of each longitudinal section 30 have a similar configuration. That is, the first to third outer ribs 33 to 35 are each triangular in shape, and their upper ends connect to the first intermediate section 41 of the upper joint section 4, which will be described later. The tops of the first to third outer ribs 33 to 35 form one side of the triangle, and the height between the longitudinal section 30 and the top decreases as it approaches the base section 2. The upper end of the top is located at the end of the first intermediate section 41. The lower end of the top forms the lower end of the outer rib and is located near the base section 2 on the longitudinal section 30, above the base section 2.

[0030] Furthermore, the outermost first outer rib 33, the first short portion 31, and the outer portion 40 of the upper joint 4 (described later) spread out to form approximately the same plane. Also, the innermost third outer rib 35 and the second intermediate portion 42 of the upper joint 4 (described later) spread out to form approximately the same plane.

[0031] Of course, the position, number, and shape of the outer ribs provided on each longitudinal section 30 are not limited to these and can be determined as appropriate. Furthermore, in each longitudinal section 30, outer ribs may be provided on the second section 30B in addition to or instead of the first section 30A, or outer ribs may not be provided on any of the longitudinal sections 30.

[0032] [(4) Upper joint] The upper joint portion 4 is a flange-like 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 Figures 1-6). The upper joint portion 4 comprises 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 form a continuous portion surrounding the opening 36 of the side wall portion 3. Of course, the configuration of the upper joint portion 4 is just one example, and the shape of the upper joint portion 4 can be appropriately determined according to the shape of the skeletal structural member to which the bracket 1 is joined.

[0033] <Outer part> The outer portion 40 is located at the outer end of the bracket 1 in the longitudinal direction (see Figures 1-4, 6). The outer portion 40 is located at the upper end of the first short portion 31 and is inclined vertically in the same manner as the first short portion 31.

[0034] <Parts 1-3 (Intermediate Sections)> The two first intermediate sections 41 are each located at the upper end of the first portion 30A of the longitudinal section 30, extending inward along the longitudinal direction from both ends of the outer section 40, and facing each other in the short direction (see Figures 1-6). The longitudinal length of each first intermediate section 41 is approximately the same as the longitudinal length of the bottom section 2.

[0035] The two second intermediate sections 42 are each located at the outer end of the second portion 30B of the longitudinal section 30 and extend upward from the inner end of each first intermediate section 41. For example, each second intermediate section 42 is inclined in the vertical direction so as it moves away from the first intermediate section 41. The two second intermediate sections 42 face each other in the short direction and face each other in the longitudinal direction relative to the outer section 40.

[0036] The two third intermediate sections 43 are each located at the upper end of the second portion 30B of the longitudinal section 30, extending inward along the longitudinal direction from the upper end of each second intermediate section 42, and facing each other in the short direction. Furthermore, the two third intermediate sections 43 are located above the two first intermediate sections 41 and the outer section 40, and are located laterally to these sections.

[0037] <Inner part> The inner portion 44 is located at the inner end of the bracket 1 in the longitudinal direction (see Figures 1-6). The inner portion 44 is located at the upper end of the second short portion 32, and the inner portion 44 and each of the third intermediate portions 43 spread out to form substantially the same plane.

[0038] <Joining of the upper joint> The upper joint 4 is joined to the side member 7 and the floor member 6 by adhesive and mechanical joining means. The mechanical joining means may be, for example, bolts, friction welding, or rivets. As an example, the outer part 40, each first intermediate part 41, and each second intermediate part 42 constitute the first upper joint that is joined to the side member 7, and each third intermediate part 43 and the inner part 44 constitute the second upper joint that is joined to the floor member 6 (see Figure 1).

[0039] Specifically, 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 these portions are joined to the side member 7 and the floor member 6 by the adhesive. In addition, each first intermediate portion 41, each second intermediate portion 42, each third intermediate portion 43, and the inner portion 44 are provided with multiple joining portions 4A (see Figure 3). Following the joining with adhesive, these joining portions 4A are joined to the side member 7 or the floor member 6 by mechanical joining means.

[0040] Of course, the upper joint 4 may also be joined to the side member 7 and the floor member 6 by, for example, an adhesive and a mechanical joining means. Furthermore, the parts of the side member 7 and the floor member 6 that are joined to the upper joint 4 may be made of iron. More specifically, these parts may be made of high-tensile steel having a tensile strength of 590 MPa or more, or even more specifically, of ultra-high-tensile steel having a tensile strength of 1470 MPa or more.

[0041] [2. Second Embodiment] [(1) Overview] The bracket 1 of the second embodiment has the same configuration as the first embodiment, but differs from the first embodiment in that it is configured to connect the suspension member 5 and the side member 7 (see Figures 7-12). The bracket 1 of the second embodiment may also be configured to connect the suspension member 5 to structural members other than the side member 7.

[0042] In other words, the bracket 1 of the second embodiment has a shorter length in the left-right direction compared to the first embodiment, or in other words, a shorter length in the longitudinal direction compared to the first embodiment, and differs from the first embodiment in the configuration of the side wall portion 3 and the upper joint portion 4. The differences between the bracket 1 of the second embodiment and the first embodiment will be explained below.

[0043] [(2) Side wall section] The side wall portion 3 of the second embodiment comprises two longitudinal portions 30 and first and second short portions 31 and 32, but differs from the first embodiment in the configuration of each longitudinal portion 30 and the second short portion 32 (see Figures 7 to 12).

[0044] In other words, the longitudinal portion 30 of the second embodiment does not have the second portion 30B of the longitudinal portion 30 of the first embodiment, and is composed of a portion corresponding to the first portion 30A. That is, the longitudinal portion 30 of the second embodiment is substantially rectangular, extends in the left-right direction, and is located above the bottom surface portion 2.

[0045] Furthermore, the second short section 32 connects to the outer end of each long section 30 and faces the first short section 31. The second short section 32 has an inclination similar to that of the first short section 31 in the vertical direction, and moves away from the first short section 31 as it extends upward.

[0046] Furthermore, the first to third outer ribs 33 to 35 have the same configuration as in the first embodiment. The first outer rib 33 is located at the outer end of the longitudinal portion 30, the second outer rib 34 is located approximately in the center of the longitudinal direction of the longitudinal portion 30, and the third outer rib 35 is located at the inner end of the longitudinal portion 30.

[0047] [(3) Upper joint] The upper joint 4 of the second embodiment comprises an outer portion 40, two intermediate portions 45, and an inner portion 46, and these portions form a continuous portion surrounding the opening 36 of the side wall portion 3 (see Figures 7-12).

[0048] The outer portion 40 is located at the outer end of the bracket 1 and is configured in the same manner as in the first embodiment. The two intermediate sections 45 are flange-shaped portions located at the upper ends of the longitudinal section 30. The two intermediate sections 45 extend inward along the longitudinal direction from both ends of the outer section 40 to the inner section 46, and face each other in the front-to-back direction. The length of each intermediate section 45 in the left-to-right direction is approximately the same as the length of the bottom section 2 in the left-to-right direction.

[0049] 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 portion 32 and faces the outer portion 40 in the left-right direction. Furthermore, the inner portion 46, the second short portion 32, and the third outer rib 35 of each longitudinal portion 30 spread out to form substantially the same plane.

[0050] [(4) Joining of the upper joint] The upper joint 4 is joined to the side member 7 by adhesive and mechanical joining means, similar to the first embodiment (see Figure 7). Specifically, adhesive is applied to the outer portion 40, each intermediate portion 45, and the inner portion 46, and these portions are joined to the side member 7 by the adhesive. In addition, each intermediate portion 45 is provided with a plurality of joint portions 4A (see Figure 9). These joint portions 4A are then joined to the side member 7 by mechanical joining means. Of course, similar to the first embodiment, the upper joint 4 may be joined to the side member 7 by, for example, either adhesive or mechanical joining means.

[0051] [3. Effects] (1) According to the above embodiment, since the bracket 1 is integrally molded by die-casting aluminum, the number of parts is reduced, rigidity is improved, and weight reduction can be promoted. In addition, since the first and second inner ribs 21 and 22 that protrude from the bottom surface 2 are provided on the inside of the side wall portion 3, the rigidity of the bracket 1 is improved. Therefore, the load on assembly work and weight reduction can be promoted.

[0052] Furthermore, improving the rigidity of bracket 1 may improve the vehicle's driving safety and ride comfort. Furthermore, the above embodiment can be seen as partially applying aluminum die-casting to the bracket 1, which corresponds to a part of the skeletal structural member, rather than to the entire skeletal structural member such as the suspension member 5. Therefore, compared to forming the entire skeletal structural member by aluminum die-casting, more of the structure of the conventional skeletal structural member can be reused, making it possible to reduce costs and apply the bracket 1 to various vehicle models.

[0053] (2) Furthermore, since the first and second inner ribs 21 and 22 extend from the side wall portion 3 to the bottom joint portion 20, the rigidity of the bracket 1 can be improved. In addition, the first and second inner ribs 21 and 22 extend linearly along the lateral direction (in other words, the longitudinal direction) and the longitudinal direction (in other words, the short direction) of the vehicle, respectively. As a result, the rigidity of the bracket 1 against loads in the lateral and longitudinal directions of the vehicle is improved.

[0054] (3) In addition, first to third outer ribs 33 to 35 are provided on each longitudinal portion 30. This improves the rigidity of the bracket 1. (4) In addition, a gap is provided between the lower ends of the first to third outer ribs 33 to 35 and the bottom surface portion 2. This makes it possible to reduce the weight of the bracket 1 while suppressing a decrease in rigidity.

[0055] (5) Furthermore, the bracket 1 of the first embodiment is joined to the side member 7 by the outer portion 40, each first intermediate portion 41, and each second intermediate portion 42, and is joined to the floor member 6 by each third intermediate portion 43 and the inner portion 44. Therefore, even when the bracket 1 is joined to multiple members, it is possible to reduce the load of assembly work and reduce weight.

[0056] (6) Furthermore, each longitudinal portion 30 of the bracket 1 in the first embodiment extends in a planar manner from the longitudinally extending edge of the bottom surface portion 2 to the first to third intermediate portions 41 to 43. This improves the rigidity of the bracket 1 against loads in the lateral direction (in other words, the longitudinal direction) of the vehicle.

[0057] [4. Other Embodiments] (1) The bracket 1 of the first embodiment may be joined to two other structural members other than the floor member 6 and the side member 7, or it may be joined to the floor member 6 or the side member 7 and the other structural members. The bracket 1 of the second embodiment may be joined to other structural members other than the side member 7. The bracket 1 of the first embodiment may also be configured to join the suspension member 5 to three or more structural members.

[0058] (2) The bracket 1 of the first and second embodiments may be configured to connect a suspension member provided around the suspension of the front wheel of the vehicle with at least one skeletal structural member.

[0059] (3) Multiple functions of one component in the above embodiment may be realized by multiple components, or one function of one component may be realized by multiple components. Also, multiple functions of multiple components may be realized by one component, or one function realized by multiple components may be realized by one component. Furthermore, some of the configurations of the above embodiment may be omitted. Also, at least some of the configurations of the above embodiment may be added to or replaced with the configurations of other above embodiments.
