Description

[Technical Field]

[0001] The present disclosure relates to a joining member used to join an instrument panel reinforcement to a vehicle body. [Background technology]

[0002] Patent Document 1 discloses a bracket, which is a pipe-shaped member extending in the vehicle width direction and is a joining member used to join the end of an instrument panel reinforcement that supports a steering wheel to the vehicle body. This bracket includes a mounting surface portion for mounting to the vehicle body and a bent surface portion that extends perpendicularly from the edge of the mounting surface portion and is formed to surround the mounting surface portion. The bent surface portion has a pair of joining portions that face each other in the vehicle width direction and are joined to the instrument panel reinforcement. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-10509 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in order to ensure rigidity, the above-mentioned bracket is formed so that the mounting surface portion and the bent surface portion surround the instrument panel reinforcement, which increases the weight and is detrimental to reducing the weight of the vehicle.

[0005] An object of one aspect of the present disclosure is to provide a joining member that can improve rigidity while suppressing an increase in weight. [Means for solving the problem]

[0006] One aspect of the present disclosure is a first joining member used to join an instrument panel reinforcement mounted on a vehicle in a state extending in the vehicle width direction to a vehicle body, the first joining member having an upper body fastening surface and a lower body fastening surface. The upper body fastening surface is fastened to the body. The lower body fastening surface is located below the upper body fastening surface and fastened to the body. The first joining member is configured to be able to hold the instrument panel reinforcement between the upper body fastening surface and the lower body fastening surface. A virtual line is defined as a line that is perpendicular to a virtual plane connecting the upper body fastening surface and the lower body fastening surface and that passes through a central axis extending in the vehicle width direction of the instrument panel reinforcement when held by the first joining member. The distance from the central axis along the virtual line to the virtual plane is equal to or less than the distance from the central axis along the virtual line to the outer circumferential surface of the instrument panel reinforcement.

[0007] In this configuration, the length of the path connecting the instrument panel reinforcement with the upper and lower body fastening surfaces, which is part of the transmission path through which the force from the steering supported by the instrument panel reinforcement is transmitted to the vehicle body, tends to be shortened. This improves the rigidity of the first joint member. As a result, the structure of the first joint member can be simplified, preventing an increase in the weight of the first joint member.

[0008] In one aspect of the present disclosure, the first joint member may be configured to cover a portion of the outer peripheral surface in the circumferential direction around the outer peripheral surface. At least one of the first fastening holes provided on the upper body fastening surface and the lower body fastening surface may be located near the instrument panel reinforcement. With this configuration, the first joint member can hold the instrument panel reinforcement without covering the entire outer peripheral surface in the circumferential direction, thereby suppressing an increase in the weight of the first joint member compared to a configuration in which the outer peripheral surface is covered in the circumferential direction. Furthermore, because at least one first fastening hole is located near the instrument panel reinforcement, the length of the path connecting the instrument panel reinforcement and at least one of the first fastening holes on the upper body fastening surface and the first fastening hole on the lower body fastening surface, which is part of the transmission path, tends to be shorter. This improves the rigidity of the first joint member.

[0009] In one aspect of the present disclosure, the first joint member may further include a connecting portion that connects the upper body fastening surface and the lower body fastening surface and holds the outer peripheral surface. With this configuration, the first joint member can be configured as a single part.

[0010] One aspect of the present disclosure is a second joining member used to join an instrument panel reinforcement mounted on a vehicle while extending in the vehicle width direction to a vehicle body, the second joining member comprising an instrument panel fastening surface and an extension surface. The instrument panel fastening surface fastens the instrument panel reinforcement. The extension surface extends from an edge of the instrument panel fastening surface. A second fastening hole is provided in the instrument panel fastening surface. A weld is provided on the edge of the extension surface to join the extension surface to the body. In the second joining member, the section from the weld on the extension surface to the second fastening hole on the instrument panel fastening surface is formed in a substantially flat shape.

[0011] In this configuration, the length of the path connecting the second fastening hole in the instrument panel fastening surface and the vehicle body, which is part of the transmission path, tends to be shorter. This improves the rigidity of the second joining member. As a result, the structure of the second joining member can be simplified. For example, when the second joining member is combined with another member for joining the instrument panel reinforcement to the vehicle body, weight increase can be suppressed.

[0012] One aspect of the present disclosure is a joint structure including the first joint member and the second joint member. The instrument panel fastening surface has an upper instrument panel fastening surface and a lower instrument panel fastening surface located below the upper instrument panel fastening surface. The upper instrument panel fastening surface and the lower instrument panel fastening surface each have a second fastening hole. The extension surface has an upper extension surface extending from an edge of the upper instrument panel fastening surface and a lower extension surface extending from an edge of the lower instrument panel fastening surface. The upper instrument panel fastening surface is fastened to the upper body fastening surface. The lower instrument panel fastening surface is fastened to the lower body fastening surface.

[0013] In this configuration, the length of the transmission path via the first and second joint members is likely to be shortened, thereby improving the rigidity of the joined structure. As a result, the structure of the joined structure can be simplified, and an increase in the weight of the joined structure can be suppressed. [Brief explanation of the drawings]

[0015] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings. [1. Configuration] <Joined structure> The joint structure 100 shown in FIGS. 1 to 3 is used to join an instrument panel reinforcement 200, which is mounted on a vehicle in a state extending in the vehicle width direction (in other words, the left-right direction of the vehicle), to the body of the vehicle.

[0016] The instrument panel reinforcement 200 is a pipe-shaped member, and has a central axis A extending in the vehicle width direction. As shown in FIG. 3, in this embodiment, the cross-sectional shape of the instrument panel reinforcement 200 perpendicular to the central axis A is substantially circular. Note that the cross-sectional shape of the instrument panel reinforcement perpendicular to the central axis is not limited to a circular shape, and may be, for example, a rectangular shape. The instrument panel reinforcement 200 supports the steering.

[0017] The joint structure 100 is provided at both ends of the instrument panel reinforcement 200 and is fixed to pillars 300 shown in FIGS. 1 and 2 that constitute the body of the vehicle by a plurality of welds 400 formed by, for example, spot welding or the like. The pillars 300 are, for example, the driver's seat side pillar and the passenger seat side pillar. In the following description, the upper, lower, front, rear, right, and left of the vehicle will be simply referred to as upper, lower, front, rear, right, and left. As shown in FIGS. 1 to 3, the joint structure 100 includes a first joint member 1, a second joint member 2, and a fastening member 3. The joint structure 100 is formed by fastening the first joint member 1 and the second joint member 2 together with the fastening member 3.

[0018] <First joining member> The first joint member 1 is, for example, a bracket that holds the instrument panel reinforcement 200 and is fastened to the vehicle body (in this embodiment, a second joint member 2, which will be described later). As shown in FIG. 4 , the first joint member 1 includes an upper fastening portion 11, two upper walls 112, a lower fastening portion 12, two lower walls 122, and a connecting portion 13.

[0019] The upper fastening portion 11 is a rectangular flat plate and has an upper body fastening surface 111 for fastening to the second joining member 2 described below. The upper body fastening surface 111 extends in the vertical and horizontal directions and is substantially planar. A substantially planar surface may mean a flat surface, or a surface that is not completely flat and has a slight curve or slight bend. The upper fastening portion 11 is provided with a first upper fastening hole 113. The first upper fastening hole 113 penetrates the upper body fastening surface 111 in the front-to-rear direction.

[0020] The two upper walls 112 extend rearward from the left and right edges of the upper fastening portion 11 that extend in the vertical direction, approximately perpendicular to the upper body fastening surface 111. Upper abutment portions 114 are provided at the lower ends of the two upper walls 112, respectively, that extend outward from the two upper walls 112 and abut against the outer peripheral surface 201 of the instrument panel reinforcement 200.

[0021] The lower fastening portion 12 is located below the upper fastening portion 11 with a gap therebetween. The lower fastening portion 12 is a rectangular flat plate and has a lower body fastening surface 121 for fastening to the second joining member 2 described below. The lower body fastening surface 121 extends in the up-down and left-right directions and is generally flat. The lower fastening portion 12 is provided with a first lower fastening hole 123. The first lower fastening hole 123 penetrates the lower body fastening surface 121 in the front-rear direction.

[0022] The two lower walls 122 extend rearward from the left and right edges of the lower fastening portion 12 that extend in the up-down direction, approximately perpendicular to the lower body fastening surface 121. Lower abutment portions 124 are provided at the upper ends of the two lower walls 122, respectively, that extend outward from the two lower walls 122 and abut against the outer peripheral surface 201 of the instrument panel reinforcement 200.

[0023] The connecting portion 13 is a plate-like member that curves along the outer peripheral surface 201 of the instrument panel reinforcement 200, and connects the upper fastening portion 11 and the lower fastening portion 12. In this embodiment, the connecting portion 13 curves so as to protrude forward. The connecting portion 13 abuts against the outer peripheral surface 201 of the instrument panel reinforcement 200. As shown in FIG. 3 , the connecting portion 13 has a substantially flat planar portion 132 in a central portion in the circumferential direction going around the outer peripheral surface 201 of the instrument panel reinforcement 200.

[0024] 4 and 7, the length of the connecting portion 13 in the left-right direction is longer than the distance between the two upper walls 112 and the distance between the two lower walls 122. The connecting portion 13 has two notches 131 aligned along the circumferential direction on each of its left and right edges extending in the circumferential direction. This allows the connecting portion 13 to abut against the outer peripheral surface 201 of the instrument panel reinforcement 200 at a constant length along the central axis A, while the notches 131 can reduce the overall area of ​​the connecting portion 13. As a result, the first connecting member 1 can stably hold the instrument panel reinforcement 200, leading to a reduction in the weight of the first connecting member 1.

[0025] 3 and 7 , the first joint members 1 can hold the instrument panel reinforcement 200 between the upper fastening portion 11 and the lower fastening portion 12. In this embodiment, the first joint members 1 hold the outer peripheral surface 201 of the instrument panel reinforcement 200 by the upper contact portions 114, the lower contact portions 124, and the connecting portions 13. The first joint members 1 cover only a portion of the outer peripheral surface 201 of the instrument panel reinforcement 200 along the circumferential direction around the outer peripheral surface 201 on a cross section perpendicular to the central axis A. In this embodiment, the upper contact portions 114, the lower contact portions 124, and the connecting portions 13 cover approximately half of the outer peripheral surface 201 of the instrument panel reinforcement 200 in the circumferential direction.

[0026] As shown in FIG. 3 , in a state in which the first joint members 1 hold the instrument panel reinforcement 200, a distance t1 from the central axis A along the imaginary line L to the imaginary plane P is equal to or less than a distance t2 from the central axis A along the imaginary line L to the outer peripheral surface 201 of the instrument panel reinforcement 200. The imaginary plane P is a plane that connects the upper body fastening surface 111 and the lower body fastening surface 121. The imaginary line L is a line that is perpendicular to the imaginary plane P and passes through the central axis A of the instrument panel reinforcement 200 in a state in which it is held by the first joint members 1. In this embodiment, the distance t2 is the radius of a circle formed by the outer peripheral surface 201 of the instrument panel reinforcement 200, and therefore the distance t1 is equal to or less than this radius.

[0027] At least one of the first upper fastening hole 113 of the upper fastening portion 11 and the first lower fastening hole 123 of the lower fastening portion 12 is located near the instrument panel reinforcement 200 in a state where it is held by the first joint member 1. In this embodiment, as shown in FIG. 7 , when the joined structure 100 is viewed from the front-rear direction, the center point of the first upper fastening hole 113 is located below the center between the upper end of the upper fastening portion 11 and the upper end of the instrument panel reinforcement 200 in a state where it is held by the first joint member 1. In other words, "near the instrument panel reinforcement 200" means being located below the center. Note that the center point of the first lower fastening hole 123 may also be located above the center between the lower end of the lower fastening portion 12 and the lower end of the instrument panel reinforcement 200 in a state where it is held by the first joint member 1.

[0028] When the first joining member 1 holds the instrument panel reinforcement 200, the first upper fastening hole 113 and the first lower fastening hole 123 are preferably arranged in positions that are symmetrical with respect to the central axis A of the instrument panel reinforcement 200, but they may also be arranged in positions that are not symmetrical with respect to the axis.

[0029] <Second joining member> The second joint member 2 is, for example, a gusset that is part of the vehicle body, and is fastened to the above-mentioned first joint member 1 and fixed to the pillar 300 by welding. As shown in FIG. 5 , the second joint member 2 includes a main body portion 21 and an extension portion 22.

[0030] The main body portion 21 has an upper instrument panel fastening surface 211, a second upper fastening hole 212, a lower instrument panel fastening surface 213, a second lower fastening hole 214, a recessed surface 215, two inclined surfaces 216, an upper surface 217, a lower surface 218, and a side surface 219.

[0031] The upper instrument panel fastening surface 211 is a rectangular surface for fastening the instrument panel reinforcement 200 via the first joint member 1. The upper instrument panel fastening surface 211 extends in the up-down and left-right directions and is generally flat. The upper instrument panel fastening surface 211 is provided with second upper fastening holes 212. The second upper fastening holes 212 penetrate the upper instrument panel fastening surface 211 in the front-rear direction. As shown in FIG. 6 , the upper instrument panel fastening surface 211 abuts against the upper body fastening surface 111 so that the second upper fastening holes 212 overlap with the first upper fastening holes 113 of the upper body fastening surface 111 of the first joint member 1. Then, by inserting the fastening member 3 (e.g., a bolt) shown in Figure 1 into the second upper fastening hole 212 and the first upper fastening hole 113, the upper instrument panel fastening surface 211 is fastened to the upper body fastening surface 111, and the first joining member 1 is fixed to the second joining member 2.

[0032] As shown in FIG. 5 , the lower instrument panel fastening surface 213 is located below the upper instrument panel fastening surface 211 with a gap therebetween. The lower instrument panel fastening surface 213 is a rectangular surface for fastening the instrument panel reinforcement 200 via the first joint member 1. The lower instrument panel fastening surface 213 extends in the up-down and left-right directions and is generally planar. The lower instrument panel fastening surface 213 is provided with a second lower fastening hole 214. The second lower fastening hole 214 penetrates the lower instrument panel fastening surface 213 in the front-rear direction. As shown in FIG. 6 , the lower instrument panel fastening surface 213 abuts against the lower body fastening surface 121 such that the second lower fastening hole 214 overlaps with the first lower fastening hole 123 of the lower body fastening surface 121 of the first joint member 1. Then, by inserting the fastening member 3 (e.g., a bolt) shown in Figure 1 into the second lower fastening hole 214 and the first lower fastening hole 123, the lower instrument panel fastening surface 213 is fastened to the lower body fastening surface 121, and the first joining member 1 is fixed to the second joining member 2.

[0033] As shown in FIG. 5 , the recessed surface 215 is a rectangular surface located between the upper instrument panel fastening surface 211 and the lower instrument panel fastening surface 213. The recessed surface 215 extends in the vertical and horizontal directions and is generally flat. The recessed surface 215 is located forward of an imaginary plane connecting the upper instrument panel fastening surface 211 and the lower instrument panel fastening surface 213. The upper instrument panel fastening surface 211 and the recessed surface 215 are connected to the lower instrument panel fastening surface 213 and the recessed surface 215 by two inclined surfaces 216. As a result, as shown in FIG. 3 , a space S is formed in the main body 21 into which the connecting portion 13 of the first joining member 1 can be fitted when the first joining member 1 is fastened to the second joining member 2. When the first joining member 1 is fastened to the second joining member 2, the recessed surface 215 abuts against the flat portion 132 of the connecting portion 13 of the first joining member 1.

[0034] As shown in FIG. 5, the upper surface 217 extends forward from an upper edge of the upper instrument panel fastening surface 211 that extends in the left-right direction. The lower surface 218 faces the upper surface 217 and extends forward from a lower edge of the lower instrument panel fastening surface 213 that extends in the left-right direction.

[0035] The side surface 219 extends forward from the right edges of the upper instrument panel fastening surface 211, the lower instrument panel fastening surface 213, the recessed surface 215, and the two inclined surfaces 216, and connects the upper surface 217 and the lower surface 218. The side surface 219 faces the pillar 300.

[0036] The extending portion 22 is provided at the left end of the main body portion 21 and abuts against the pillar 300. The extending portion 22 has a first extending portion 221, a second extending portion 222, and a third extending portion 223. The first extending portion 221 is a plate-like portion that is connected to the upper instrument panel fastening surface 211, the lower instrument panel fastening surface 213, the recessed surface 215, and the two inclined surfaces 216, and extends in the vertical and horizontal directions. The first extending portion 221 is provided so as not to have any step with respect to the upper instrument panel fastening surface 211 and the lower instrument panel fastening surface 213. The first extending portion 221 is also provided so as to have a step with respect to the recessed surface 215 and the two inclined surfaces 216. The first extending portion 221 has an upper extending surface 224 and a lower extending surface 225.

[0037] The upper extension surface 224 extends from the left edge of the upper instrument panel fastening surface 211, which extends in the vertical direction. The upper extension surface 224 extends in the vertical and horizontal directions and is generally planar. In this embodiment, the upper extension surface 224 extends while bending slightly rearward relative to the upper instrument panel fastening surface 211. The upper extension surface 224 and the upper instrument panel fastening surface 211 may extend in the same plane. As shown in FIG. 1 , a weld 400 that joins the extension portion 22 and the pillar 300 is provided on the edge of the upper extension surface 224. In the second joining member 2, the section from the weld 400 on the upper extension surface 224 to the second upper fastening hole 212 on the upper instrument panel fastening surface 211 is generally planar.

[0038] As shown in FIG. 5 , the lower extension surface 225 extends from the left edge of the lower instrument panel fastening surface 213, which extends in the vertical direction. The lower extension surface 225 extends in the vertical and horizontal directions and is generally planar. In this embodiment, the lower extension surface 225 extends while bending slightly rearward relative to the lower instrument panel fastening surface 213. The lower extension surface 225 and the lower instrument panel fastening surface 213 may extend in the same plane. As shown in FIG. 1 , a weld 400 that joins the extension portion 22 and the pillar 300 is provided on the edge of the lower extension surface 225. The second joining member 2 has a generally planar shape from the weld 400 on the lower extension surface 225 to the second lower fastening hole 214 on the lower instrument panel fastening surface 213.

[0039] As shown in FIG. 5, the second extending portion 222 is a plate-like portion that is connected to the upper surface 217 and the first extending portion 221 and extends in the up-down and front-rear directions. The third extending portion 223 is a plate-like portion that is connected to the lower surface 218 and the first extending portion 221 and extends in the up-down and front-rear directions.

[0040] [2.Effects] According to the embodiment described above in detail, the following effects can be obtained. (2a) In this embodiment, when the first joint member 1 holds the instrument panel reinforcement 200, the distance t1 from the central axis A along the imaginary line L to the imaginary plane P is equal to or less than the radius of the circle formed by the outer peripheral surface 201 of the instrument panel reinforcement 200. This tends to shorten the lengths of the path connecting the instrument panel reinforcement 200 and the upper body fastening surface 111 and the path connecting the instrument panel reinforcement 200 and the lower body fastening surface 121, which are parts of the transmission path through which the force from the steering supported by the instrument panel reinforcement 200 is transmitted to the pillar 300. This improves the rigidity of the first joint member 1. As a result, the structure of the first joint member 1 can be easily simplified, thereby suppressing an increase in the weight of the first joint member 1.

[0041] (2b) In this embodiment, in the second joint member 2, the section from the welded portion 400 on the upper extension surface 224 to the second upper fastening hole 212 on the upper instrument panel fastening surface 211 and the section from the welded portion 400 on the lower extension surface 225 to the second lower fastening hole 214 on the lower instrument panel fastening surface 213 are substantially planar. This tends to shorten the lengths of the path connecting the second upper fastening hole 212 on the upper instrument panel fastening surface 211 to the pillar 300 and the path connecting the second lower fastening hole 214 on the lower instrument panel fastening surface 213 to the pillar 300, which are parts of the transmission path. This improves the rigidity of the second joint member 2. As a result, the structure of the second joint member 2 can be easily simplified, which helps prevent an increase in the weight of the second joint member 2.

[0042] (2c) As described above, in this embodiment, the transmission paths in the first joint member 1 and the second joint member 2 tend to be short, and therefore the overall length of the transmission path through the first joint member 1 and the second joint member 2 tends to be short. This can improve the rigidity of the entire joined structure 100. As a result, the structure of the joined structure 100 can be easily simplified, and an increase in the weight of the joined structure 100 can be suppressed.

[0043] (2d) In this embodiment, the first joining member 1 can hold the instrument panel reinforcement 200 without covering the entire outer peripheral surface 201 in the circumferential direction, and therefore, an increase in the weight of the first joining member 1 can be suppressed compared to a configuration in which the outer peripheral surface 201 is covered entirely in the circumferential direction.

[0044] (2e) In this embodiment, at least the first upper fastening hole 113 is located near the instrument panel reinforcement 200. Therefore, the length of the path connecting the instrument panel reinforcement 200 and the first upper fastening hole 113 of the upper body fastening surface 111, which is part of the transmission path, is likely to be shortened. This can improve the rigidity of the first joint member 1. In addition, the length between the first upper fastening hole 113 and the first lower fastening hole 123 is likely to be shortened, i.e., the length of the path connecting the first upper fastening hole 113 and the first lower fastening hole 123, which is part of the transmission path, is likely to be shortened, so the rigidity of the first joint member 1 can be improved.

[0045] (2f) In this embodiment, the upper fastening portion 11 having the upper body fastening surface 111 and the lower fastening portion 12 having the lower body fastening surface 121 are connected by the connecting portion 13, so that the first joining member 1 can be constructed from a single part.

[0046] In this embodiment, the first upper fastening hole 113 and the first lower fastening hole 123 correspond to an example of a first fastening hole, and the second upper fastening hole 212 and the second lower fastening hole 214 correspond to an example of a second fastening hole.

[0047] 3. Other Embodiments Although the embodiments of the present disclosure have been described above, it goes without saying that the present disclosure is not limited to the above-described embodiments and can take on various forms.

[0048] (3a) In the above embodiment, the joining structure 100 is provided at the end of the instrument panel reinforcement 200, but the location where the joining structure is provided is not limited to the end. For example, the joining structure may be provided at a position between the end of the instrument panel reinforcement and the fixing member that fixes the steering wheel to the instrument panel reinforcement, closer to the fixing member than the end.

[0049] (3b) In the above embodiment, the first joint member 1 has the connecting portion 13. However, the first joint member 1 may have no connecting portion. For example, as shown in FIG. 8, the first joint member 1a may have two components: an upper fastening portion 11a having an upper body fastening surface and a lower fastening portion 12a having a lower body fastening surface. In this case, the instrument panel reinforcement 200 and the second joint member 2a are likely to be configured closer to each other.

[0050] (3c) In the above embodiment, the connection structure 100 includes the first connection member 1 and the second connection member 2. However, for example, the first connection member may be fastened to the pillar 300, and the second connection member may be fastened to the instrument panel reinforcement 200.

[0051] (3d) The function of one component in the above embodiments may be distributed among multiple components, or the functions of multiple components may be integrated into one component. Also, part of the configuration of the above embodiments may be omitted. Furthermore, at least part of the configuration of the above embodiments may be added to or substituted for the configuration of another of the above embodiments.
