Description

Bracket for mounting electronic components to the vehicle body

[0001] The present invention relates to a bracket for mounting an electronic component for a vehicle to a vehicle body.

[0002] A vehicle is known in which a regenerative power system unit is provided between a rear side trim that forms the rear side of the passenger compartment and an inner panel that forms a body panel above the rear wheel housing (see Patent Document 1). The regenerative power system unit is attached to the passenger compartment side of the inner panel.

[0003] JP 2011-183943 A

[0004] In the above-described conventional technology, the position of the rear side trim in the vehicle width direction is set according to the length of the regenerative power system unit in the vehicle width direction in order to accommodate the regenerative power system unit between the inner panel and the rear side trim. Therefore, in the above-described conventional technology, if the length of the regenerative power system unit in the vehicle width direction is long, the position of the rear side trim in the vehicle width direction extends inward in the vehicle width direction, resulting in a problem of narrowing the vehicle interior.

[0005] The problem to be solved by the present invention is to provide a bracket that can prevent the vehicle interior from becoming narrower when a vehicle electronic component is attached to the vehicle body.

[0006] The present invention solves the above problem by using a bracket having a top surface and a flange attached to the body side inner panel, which has a hat-shaped cross section that passes through the flange and includes the flange and top surface in a cross section perpendicular to the top surface, when attaching vehicle electronic components to a vehicle body that includes a body side inner panel and a body side outer panel located outboard of the body side inner panel in the vehicle width direction, fixing a first vehicle electronic component to a position on the flange side of the top surface in the cross section, fixing a second vehicle electronic component to the surface of the top surface opposite to the position where the first vehicle electronic component is fixed, and arranging the second vehicle electronic component between the body side inner panel and the body side outer panel with the flange attached to the body side inner panel.

[0007] According to the present invention, it is possible to prevent the vehicle interior from becoming narrower when vehicle electronic components are attached to the vehicle body.

The left-right direction of the vehicle body is also referred to as the vehicle width direction, and the up-down direction of the vehicle body is also referred to as the height direction.

[0010] In the following description, the front side of the vehicle body (front vehicle body), rear side of the vehicle body (rear vehicle body), right side of the vehicle body (right side of the vehicle body), left side of the vehicle body (left side of the vehicle body), upper side of the vehicle body (upper side of the vehicle body), and lower side of the vehicle body (lower side of the vehicle body) correspond to the front side, rear side, right side, left side, upper side, and lower side of a passenger riding in the vehicle, respectively. The right side and / or left side of the vehicle body are also referred to as the side of the vehicle body.

[0011] Also, the front side of the engine mounted on the vehicle body is defined as the front side, and viewing the vehicle body from the front side of the engine is referred to as viewing the vehicle body from the front. Similarly, viewing the vehicle body from the rear side is referred to as viewing the vehicle body from the back, viewing the vehicle body from the right or left side is referred to as viewing the vehicle body from the side, viewing the vehicle body from above is referred to as viewing the vehicle body from the top, and viewing the vehicle body from below is referred to as viewing the vehicle body from the bottom.

[0012] [Vehicle Body Configuration] FIG. 1 is a right side view showing an example of a vehicle body according to an embodiment of the present invention, and is a side view of a main portion showing the right side of the vehicle body. The vehicle body is a box-shaped structure (body shell) that forms a passenger compartment, an engine compartment, etc., and includes doors, a hood, etc. The vehicle body is made of steel plates such as high-tensile steel plates, and is manufactured by joining press-formed members by spot welding. The vehicle body may be a monocoque body integrated with a frame, or may be separate from the frame. Note that the vehicle body shown in FIG. 1 is a hatchback type with a back door, but the vehicle shape (vehicle type) is not particularly limited.

[0013] 1, a vehicle body 10 of this embodiment includes a body side inner panel 11, a rear wheel housing 12, a pillar 13, and a bracket 20. The body side inner panel 11 is a plate-shaped member that forms the side surface of the vehicle body on the rear side, and is made of steel plate such as high-tensile steel plate, and is manufactured by joining press-formed members by spot welding, arc welding, or the like, for example.

[0014] The rear wheel housing 12 surrounds the rear wheels, providing a space between the rear wheels and the vehicle body 10. The rear wheel housing 12 is provided below the body side inner panel 11 and extends along the outer periphery of the rear wheels. On the other hand, the pillar 13 is a frame that supports a tailgate at the rear of the vehicle body 10 (or has a member attached to support the tailgate). The pillar 13 includes a frame that supports a trunk lid at the rear of the vehicle body (or has a member attached to support the trunk lid). Examples of members that support the tailgate and trunk lid include hinges, dampers, etc.

[0015] The body side inner panel 11 shown in FIG. 1 has a rear end portion 11b on the rear side of the vehicle body and a main body portion 11a disposed on the front side of the rear end portion 11b with a gap between the rear end portion 11b and the rear end portion 11b. The main body portion 11a and the rear end portion 11b together connect a rear wheel house 12 and a pillar 13. As shown in FIG. 1, when the main body portion 11a and the rear end portion 11b are attached to the vehicle body 10, an opening O is defined by the main body portion 11a, the rear end portion 11b, the rear wheel house 12, and the pillar 13. The size of the opening O (or the distance between the main body portion 11a and the rear end portion 11b in the fore-and-aft direction of the vehicle body) can be appropriately set depending on the desired strength (or rigidity) of the body side inner panel 11. Note that while the main body portion 11a and the rear end portion 11b shown in FIG. 1 are separate bodies, the main body portion 11a and the rear end portion 11b may be molded as an integrated member by providing the opening O in the body side inner panel 11.

[0016] The bracket 20 is a member for attaching various electronic components used in a vehicle (hereinafter also referred to as vehicle electronic components) to the vehicle body 10. The vehicle electronic components are not particularly limited as long as they are electronic components used in a vehicle, and examples thereof include an automobile control unit, an autonomous driving control unit, a fuel injection control unit, a power supply inverter unit, and an electrical equipment control unit. The bracket 20 is made of, for example, a steel plate such as a high-tensile steel plate, and is manufactured by joining press-formed members by spot welding, bolt fastening, or the like. As shown in FIG. 1 , the bracket 20 is attached between the main body portion 11 a and the rear end portion 11 b so as to connect the main body portion 11 a and the rear end portion 11 b. In other words, the bracket 20 attached to the vehicle body 10 functions as a stiffener for the body side inner panel 11.

[0017] FIG. 2 is a cross-sectional view taken along line A-A in FIG. 1 , showing a main portion of the cross section taken along line A-A when the vehicle is viewed from the front. As shown in FIG. 2 , the vehicle body 10 of this embodiment includes a body side outer panel 14 located outward in the vehicle width direction from the body side inner panel 11. Like the body side inner panel 11, the body side outer panel 14 is a plate-shaped member that forms the rear side of the vehicle body. It is made of a steel plate such as a high-tensile steel plate and is manufactured by joining press-formed members together by spot welding, arc welding, or the like. The body side outer panel 14 is located at the outermost side of the vehicle body 10 (at the leftmost side in FIG. 2 ), and the body side inner panel 11 is located inward from the body side outer panel 14 (at the right side in FIG. 2 ).

[0018] The body side inner panel 11 and the body side outer panel 14 may be joined to each other by spot welding or the like. For example, in the vehicle body 10 shown in FIG. 2 , the body side inner panel 11 and the body side outer panel 14 are joined together and, together with the pillar 13, form a box-shaped cross-sectional shape (closed cross-sectional shape) in a cross section perpendicular to the longitudinal direction of the vehicle body 10. Furthermore, when the ends of the body side inner panel 11 and the body side outer panel 14 are joined to the rear wheel panel that constitutes the rear wheel house 12, the body side inner panel 11, the rear wheel house 12, the pillar 13, and the body side outer panel 14 form a box-shaped cross-sectional shape in a cross section perpendicular to the longitudinal direction of the vehicle body 10. Note that the distance between the body side inner panel 11 and the body side outer panel 14 in the vehicle width direction can be set as appropriate within a range in which the vehicle body 10 has the desired strength (or rigidity).

[0019] 3 is a cross-sectional view taken along line B-B in FIG. 1, particularly showing the main parts of the vehicle body when viewed from the right rear side. As shown in FIG. 3, the bracket 20 positions vehicle electronic components in the space formed between the body side inner panel 11 and the body side outer panel 14 above the rear wheel housing 12. The bracket 20 of this embodiment will now be described.

[0020] [Bracket Configuration] Figure 4 is a perspective view showing the bracket 20 shown in Figure 3. The bracket 20 of this embodiment has a top surface and a flange, and has a hat-shaped cross section including the flange and the top surface in a cross section passing through the flange and perpendicular to the top surface. The top surface is a generally flat portion of the bracket 20, and the flange is a flat portion that attaches the bracket 20 to the body side inner panel 11.

[0021] As an example, the bracket 20 shown in Fig. 4 is a bracket 20 made up of multiple members including a first bracket 21 and a second bracket 22 attached to the first bracket 21. In the bracket 20 shown in Fig. 4, the second bracket 22 is fastened to the first bracket 21 with bolts. The second bracket 22 forms a top surface 22a when attached to the first bracket 21.

[0022] The first bracket 21 includes a first bracket 21 on the front side of the vehicle body and a first bracket 21 on the rear side of the vehicle body. The first bracket 21 on the front side of the vehicle body has a front flange 21a that is arranged on the front side of the vehicle body when attached to the vehicle body 10, a side portion 21b that protrudes from the front flange 21a toward the top surface 22a, and an attachment portion 21c that extends along the second bracket 22 and to which the second bracket 22 is attached. On the other hand, the first bracket 21 on the rear side of the vehicle body has a rear flange 21d that is arranged on the rear side of the vehicle body when attached to the vehicle body 10, a side portion 21e that protrudes from the rear flange 21d toward the top surface 22a, and an attachment portion 21f.

[0023] Fig. 5 is a cross-sectional view of the bracket 20 at cross section S in Fig. 4. Cross section S passes through the front flange 21 a and the rear flange 21 d and is perpendicular to the top surface 22 a, and Fig. 5 shows the cross-sectional shape of the bracket 20 when viewed from above at cross section S. As shown in Fig. 5, the bracket 20 shown in Fig. 4 has a hat-shaped cross-section at cross section S that includes the front flange 21 a, the rear flange 21 d, the side portions 21 b, 21 e, and the top surface 22 a.

[0024] The first bracket 21 may have a C-shaped cross section at the portion on the front side of the vehicle body in the cross section S. For example, the first bracket 21 shown in Fig. 5 has a C-shaped cross section at the cross section S, which is made up of a front flange portion 21a, a side portion 21b, and an attachment portion 21c on the front side of the vehicle body.

[0025] The rear flange 21d may also have a positioning protrusion 17 for attaching the rear flange 21d to the body side inner panel 11. For example, the rear flange 21d shown in Figures 4 and 5 is provided with a protrusion 17 that determines the position of the bracket 20 relative to the body side inner panel 11 when attaching the bracket 20, to which a vehicle electronic component or the like is attached, to the body side inner panel 11. A hole is provided in the body side inner panel 11 at a portion corresponding to the protrusion 17, and the bracket 20 is supported by the body side inner panel 11 by inserting the protrusion 17 into the hole.

[0026] The cross-sectional shape of bracket 20 does not need to be strictly hat-shaped as a whole, as long as it includes a portion corresponding to the flange and a portion corresponding to top surface 22a. For example, in the cross-sectional shape shown in Fig. 5, portions of front flange 21a, side portions 21b and 21e, mounting portions 21c and 21f, rear flange 21d, top surface 22a, etc. may be missing, and the cross-sectional shape may include discontinuous portions (i.e., the cross-sectional shape does not need to be continuous as a whole).

[0027] 4 is a bracket 20 made up of three members, including a first bracket 21 and a second bracket 22, each made up of two members. However, the bracket 20 may be formed from a single member. For example, the bracket 20 may be a single plate-like member made up of a front flange 21a, a side portion 21b, a top surface 22a, a side portion 21e, and a rear flange 21d. Furthermore, the attachment location to the body side inner panel 11 can be appropriately provided on the flange within a range that allows the bracket 20 to be appropriately fixed to the vehicle body 10.

[0028] 3, the front flange 21a is attached to the main body 11a, and the rear flange 21d is attached to the rear end 11b. The front flange 21a and the rear flange 21d are attached to the opening O from the inside in the vehicle width direction of the body side inner panel 11 so that their top surfaces 22a are positioned between the body side inner panel 11 and the body side outer panel 14. In other words, the front flange 21a and the rear flange 21d are fixed to the inside surface of the body side inner panel 11 in the vehicle width direction, and the bracket 20 is attached to the body side inner panel 11 so that the top surface 22a, which has a hat-shaped cross section, protrudes from the opening O of the body side inner panel 11 toward the body side outer panel 14.

[0029] FIG. 6 is a perspective view showing a vehicle electronic component fixed to the bracket 20 of FIG. 4 , showing the bracket 20 in a plan view. As shown in FIG. 6 , side portions 21 b, 21 e of the first bracket 21 support a first vehicle electronic component 31. Specifically, the first vehicle electronic component 31 is fastened to the side portions 21 b, 21 e with bolts. As described above, in the bracket 20 of this embodiment, the first vehicle electronic component 31 is fixed to a position on the flange side of the top surface 22 a at a cross section S where the bracket 20 has a hat-shaped cross section. The first vehicle electronic component 31 may also be disposed inside a recess T (see FIG. 6 ) of the hat-shaped cross section of the bracket 20, or may be disposed at a position between the flange and the top surface 22 a in the hat-shaped cross section of the bracket 20.

[0030] Meanwhile, second vehicle electronic component 32 is fixed to the surface of second bracket 22 opposite to first bracket 21. For example, second vehicle electronic component 32 shown in Fig. 6 is bolted to the surface of bracket 20 on the right side of the vehicle body opposite to first bracket 21. In this way, in bracket 20 of the present embodiment, second vehicle electronic component 32 is fixed to the surface of top surface 22a opposite to the position where first vehicle electronic component 31 is fixed. Second vehicle electronic component 32 may be lighter than first vehicle electronic component 31.

[0031] In a cross section passing through the flange and perpendicular to the top surface, the length of first vehicle electronic component 31 along the fore-and-aft direction of vehicle body 10 may be shorter than the length of second vehicle electronic component 32 along the fore-and-aft direction of vehicle body 10. For example, length L1 of first vehicle electronic component 31 along the fore-and-aft direction of vehicle body shown in FIG. 6 is shorter than length L2 of second vehicle electronic component 32 along the fore-and-aft direction of vehicle body.

[0032] Furthermore, with the flange portion attached to the body side inner panel 11, the rear end of the second vehicle electronic component 32 may be located further forward in the vehicle body than the rear end of the first vehicle electronic component 31. For example, in the bracket 20 shown in Fig. 6 , the rear end of the second vehicle electronic component 32 is located further forward in the vehicle body than the rear end of the first vehicle electronic component 31. In particular, when the flange portion of the bracket 20 is attached to the body side inner panel 11 on the rear side of the vehicle body, the rear end of the second vehicle electronic component 32 is located further forward in the vehicle body than the rear end of the first vehicle electronic component 31.

[0033] The bracket 20 to which the first vehicle electronic component 31 and the second vehicle electronic component 32 are fixed, as shown in Fig. 6, is attached to the body side inner panel 11 (main body portion 11a and rear end portion 11b) as shown in Fig. 3. The top surface 22a protrudes from the opening O of the body side inner panel 11 toward the body side outer panel 14, and is disposed between the body side inner panel 11 and the body side outer panel 14. As a result, the second vehicle electronic component 32 fixed to the outer side of the top surface 22a in the vehicle width direction is disposed between the body side inner panel 11 and the body side outer panel 14, with the front flange portion 21a and the rear flange portion 21d attached to the body side inner panel 11.

[0034] A weld bolt may be provided in the portion of the body side inner panel 11 where the front flange 21a is attached. Fig. 7 is a left side view of the vehicle body 10 of Fig. 1, with the bracket 20 omitted. In the vehicle body 10 shown in Fig. 7, a weld bolt 15 is provided in the main body 11a at a position corresponding to the attachment portion of the front flange 21a. Also, a weld nut may be provided in the portion of the body side inner panel 11 where the rear flange 21d is attached. In the vehicle body 10 shown in Fig. 7, a weld nut 16 is provided in the rear end 11b at a position corresponding to the attachment portion of the rear flange 21d.

[0035] 8A to 8C are perspective views showing an example of a procedure for attaching the bracket 20 of FIG. 6 to the vehicle body 10. First, as shown in FIG. 8A, the main body 11a is positioned within the C-shaped cross section of the front flange 21a, and the weld bolt 15 provided on the body side inner panel 11 is inserted through the hole provided in the front flange 21a. As shown in FIG. 8B, the weld bolt 15 is inserted through the hole in the front flange 21a, and then the protrusion 17 is inserted through the hole provided in the rear end 11b. As shown in FIG. 8C, the bracket 20 is supported by the body side inner panel 11, and the position of the bracket 20 relative to the body side inner panel 11 is determined. Then, the weld bolt 15 inserted into the hole in the front flange 21a is tightened with a bolt, and a bolt is inserted into the hole in the rear flange 21d at a position corresponding to the weld nut, tightening the rear flange 21d and the rear end 11b with the bolt.

[0036] The present invention relates to a bracket 20 for mounting a vehicle electronic component to a vehicle body 10, and also to a vehicle body 10 including a body side inner panel 11, a body side outer panel 14, and the bracket 20, and to an arrangement structure for a vehicle electronic component, in which the vehicle electronic component is mounted using the bracket 20 on the vehicle body 10 including the body side inner panel 11 and the body side outer panel 14. In this embodiment, the bracket 20 is mounted to the right rear of the vehicle body 10, but the bracket 20 may also be mounted to the left rear of the vehicle body 10.

[0037] [Embodiment of the Invention] According to this embodiment, a bracket 20 for attaching a vehicle electronic component to a vehicle body 10 including a body side inner panel 11 and a body side outer panel 14 provided on the outside of the body side inner panel 11 in the vehicle width direction comprises a top surface 22a and a flange portion attached to the body side inner panel 11, and has a hat-shaped cross section including the flange portion and the top surface 22a in a cross section S that passes through the flange portion and is perpendicular to the top surface 22a, A bracket 20 is provided in which a first vehicle electronic component 31 is fixed to a position on the flange side with respect to the top surface 22a, a second vehicle electronic component 32 is fixed to a surface of the top surface 22a opposite to the position where the first vehicle electronic component 31 is fixed, and the top surface 22a positions the second vehicle electronic component 32 between the body side inner panel 11 and the body side outer panel 14 in a state where the flange is attached to the body side inner panel 11. This makes it possible to utilize the space between the body side inner panel 11 and the body side outer panel 14, and to prevent a rear side trim that is positioned more inward in the vehicle width direction than the body side inner panel 11 from protruding toward the passenger compartment.

[0038] In the bracket 20 of this embodiment, the second vehicle electronic component 32 is lighter than the first vehicle electronic component 31. This reduces the moment in the vehicle width direction applied to the fixing point (flange portion) between the body side inner panel 11 and the bracket 20 compared to when a heavy vehicle electronic component is arranged on the outer side in the vehicle width direction, and reduces the strength required for the bracket 20 (flange portion), allowing the plate thickness thereof to be thinned.

[0039] In the bracket 20 of this embodiment, at the cross section S, the length L1 of the first vehicle electronic component 31 along the fore-and-aft direction of the vehicle body 10 is shorter than the length L2 of the second vehicle electronic component 32 along the fore-and-aft direction. This allows the width of the hat-shaped cross-section at the cross section S (the length in the lateral direction in FIG. 5 ) to be smaller than when a vehicle electronic component that is longer along the fore-and-aft direction of the vehicle body 10 is arranged on the inner side in the vehicle width direction. As a result, the opening O of the body side inner panel 11 can be made smaller, and a decrease in the rigidity of the rear portion of the vehicle body 10 can be suppressed. Furthermore, because the second vehicle electronic component 32 arranged on the outer side in the vehicle width direction can be arranged to protrude from the top surface 22 a, the second vehicle electronic component 32 that is larger than the first vehicle electronic component 31 can be attached to the bracket 20.

[0040] In the bracket 20 of this embodiment, the flange portion is attached to the rear side of the body side inner panel 11, and with the flange portion attached to the body side inner panel 11, the rear end of the second vehicle electronic component 32 is located further forward in the vehicle body than the rear end of the first vehicle electronic component 31. This allows the bracket 20 to be attached to the rear of the vehicle body 10, where the distance between the body side inner panel 11 and the body side outer panel 14 in the vehicle width direction is narrow, without interfering with the second vehicle electronic component 32 and the body side outer panel 14, and the space between the body side inner panel 11 and the body side outer panel 14 can be more effectively utilized.

[0041] In the bracket 20 of this embodiment, the vehicle body 10 includes a rear wheel house 12 provided below the body side inner panel 11 and a pillar 13 supporting a tailgate, and the body side inner panel 11 has a rear end portion 11b on the rear side of the vehicle body that connects the rear wheel house 12 and the pillar 13, and a main body portion 11a disposed on the front side of the rear end portion 11b with a gap between the rear end portion 11b and the rear end portion 11b, and the flange portion is attached to the main body portion 11a and the rear end portion 11b. By connecting the rear wheel house 12 and the pillar 13 by the rear end portion 11b of the body side inner panel 11 in this manner, the torsional rigidity around the pillar 13 supporting the tailgate can be improved, and by disposing the rear end of the main body portion 11a on the front side of the vehicle body 10, the size of the opening O in the fore-and-aft direction of the vehicle body can be increased, thereby reducing the vehicle weight. Furthermore, by connecting the main body portion 11 a and the rear end portion 11 b with the bracket 20 , the bracket 20 functions as a stiffener for the body side inner panel 11 , thereby improving the torsional rigidity around the pillar 13 .

[0042] The bracket 20 of this embodiment includes a first bracket 21 and a second bracket 22 attached to the first bracket 21, the first bracket 21 having the flange portion and a side portion 21b that protrudes from the flange portion toward the top surface 22a and supports the first vehicle electronic component 31, the second bracket 22 being attached to the first bracket 21 to form the top surface, and the second vehicle electronic component 32 being fixed to the surface opposite the first bracket 21. As a result, the second bracket 22 is interposed between the second vehicle electronic component 32 and the first bracket 21, so that vibrations from the vehicle body 10 are not directly transmitted to the second vehicle electronic component 32, and input of vibrations to the second vehicle electronic component 32 can be suppressed. In other words, a vehicle electronic component that is relatively susceptible to vibrations can be attached to the bracket 20.

[0043] In the bracket 20 of this embodiment, the flange has a front flange 21a located on the front side of the vehicle body when attached to the body side inner panel 11, and a rear flange 21d located on the rear side of the vehicle body, a weld bolt 15 is provided on the portion of the body side inner panel 11 where the front flange 21a is attached, a weld nut 16 is provided on the portion of the body side inner panel 11 where the rear flange 21d is attached, the first bracket 21 has a C-shaped cross section at the front side of the vehicle body in the cross section S, and the rear flange 21d has a positioning protrusion 17 for attaching the flange to the body side inner panel 11. This allows for reduced manufacturing costs for the body side inner panel 11 compared to when positioning the bracket 20 to the body side inner panel 11 is performed using only the weld bolt 15 provided on the body side inner panel 11. Furthermore, the C-shaped cross section of front flange 21 a allows second vehicle electronic component 32 to be positioned further forward in the vehicle body than first vehicle electronic component 31. Furthermore, by providing weld nuts 16 at the portion where rear flange 21 d is attached and providing positioning protrusions 17 on rear flange 21 d, the manufacturing costs of body side inner panel 11 can be reduced and the efficiency of the bracket 20 attachment work can be improved.
