In the following description, the front, front side, rear, and rear side in the longitudinal direction of the vehicle, the upper side, upper side, lower side, and lower side in the vertical direction of the vehicle, and the left side, left side, right side, and right side in the width direction of the vehicle will be simply referred to as the front, front side, rear, rear side, upper side, upper side, lower side, lower side, left side, left side, right side, and right side, respectively. Furthermore, configurations having the same functions as those already described will be given the same reference numerals and descriptions will be omitted.

As shown in Figures 1 to 3, the support structure S has a pair of strut towers 31R, 31L arranged on the left and right sides of the motor room MR. A motor 20 for driving the vehicle is arranged between the right strut tower 31R and the left strut tower 31L. Fixed shafts 22 extending outward in the vehicle width direction are provided on the left and right ends 21R, 21L of the motor 20. The left and right fixed shafts 22 are supported by motor mounts 51R, 51L, respectively.

As shown in FIG. 2, the motor mount 51R is attached to the strut tower 31R, and the motor mount 51L is attached to the strut tower 31L. The motor mount 51R has two upper legs 52U and two lower legs 52D at the right end. The upper legs 52U are fastened to the left side surface 32L of the housing 32 of the strut tower 31R by bolts 33. Meanwhile, the lower legs 52D are fastened to the left side surface 42L of the right front side member 41, which extends in the fore-and-aft direction of the vehicle, by bolts 35 at the lower right of the motor room MR. The fastening points of the upper legs 52U and the lower legs 52D by the bolts 33, 35 are the mounting point P1 of the motor mount 51L. Although hidden and not visible in the figure, the motor mount 51L similarly has two upper legs 52U and two lower legs 52D at the left end. The upper leg 52U is fastened to the right side of the housing 32 of the strut tower 31L by a bolt 33. Meanwhile, the lower leg 52D is fastened to the right side of the left front side member 41, which extends in the vehicle front-rear direction in the lower left part of the motor room MR, by a bolt 35. The fastening points of the upper leg 52U and the lower leg 52D by the bolts 33 and 35 are the mounting point P1 of the motor mount 51L.

As shown in Figs. 1 and 3, a support member 11 is disposed between strut towers 31R and 31L and above motor 20. Support member 11 has a mounting surface 11A between strut towers 31R and 31L on which vehicle-mounted parts can be placed. Various vehicle-mounted parts 15A, 15B, 15C (see Fig. 3) can be placed on mounting surface 11A. Vehicle-mounted part 15A is, for example, a 12V battery, and can be fixed and supported by a tray 16 installed on mounting surface 11A using a fixing pin 17 (see Fig. 7). Vehicle-mounted parts 15B, 15C are, for example, a FL (Fusible Link) box, a PCT heater, a DC/DC converter, etc. Vehicle-mounted parts to be placed and supported on mounting surface 11A are not particularly limited, and various vehicle-mounted parts can be selected.

The support member 11 is made of a metal panel material and has a generally rectangular, flat plate-like shape in a plan view that is longer in the vehicle width direction than in the vehicle front-rear direction. The shape of the support member 11 is not particularly limited, and may be, for example, a lattice shape, a frame shape, a staircase shape, etc. The material of the support member 11 is also not particularly limited, and may be, for example, a punched metal, an expanded metal, a grating, etc.

The support member 11 of this embodiment is composed of a panel portion 12 that forms the mounting surface 11A, and a connecting member 13 (see FIG. 4) with an inverted U-shaped cross section that extends in the vehicle width direction along the rear edge of the panel portion 12. The connecting member 13 is fastened to the rear edge of the panel portion 12 at multiple points in its longitudinal direction by bolts 18.

The support member 11 is connected to the strut towers 31R and 31L. The right edge 11a of the support member 11 is fastened to the front bracket 34A and the rear bracket 34B by bolts 37. The front bracket 34A protrudes leftward from the front of the left side surface 32L of the housing 32 of the right strut tower 31R. The rear bracket 34B protrudes leftward from the rear of the left side surface 32L. Similarly, the left edge 11b of the support member 11 is fastened to the front bracket 34A and the rear bracket 34B by bolts 37. The front bracket 34A protrudes rightward from the front of the right side surface of the housing 32 of the left strut tower 31L. The rear bracket 34B protrudes rightward from the rear of the right side surface.

The upper surface 34a of each bracket 34A, 34B is provided with a bolt hole 36 through which a bolt 37 is inserted. The bolt fastening points between the support member 11 and the two front brackets 34A are the front connection points p1 between the support member 11 and the strut towers 31R, 31L. Similarly, the fastening points between the support member 11 and the two rear brackets 34B are the rear connection points p2 between the support member 11 and the strut towers 31R, 31L. Hereinafter, the front connection points p1 and the rear connection points p2 are collectively referred to as "connection points." Note that in this embodiment, the support member 11 and the strut towers 31R, 31L are connected by bolt fastening, but they may also be connected by welding. In the case of welding, the weld points become the connection points.

The attachment point P1 of the motor mounts 51R, 51L is located behind the front connection point p1 and in front of the rear connection point p2. Furthermore, the attachment point P1 of the upper end and upper leg 52U of the motor mounts 51R, 51L is located above the front connection point p1 and the rear connection point p2, more specifically, above the upper surfaces 34a of the two brackets 34A, 34B. Furthermore, the attachment point P1 of the lower end and lower leg 52D of the motor mounts 51R, 51L is located below the front connection point p1 and the rear connection point p2, more specifically, below the upper surfaces 34a of the two brackets 34A, 34B. In other words, the front connection point p1, the rear connection point p2, and the right edge 11a of the support member 11 connected thereto are arranged to straddle the upper leg 52U of the motor mount 51R. Similarly, the front connection point p1, the rear connection point p2, and the left edge 11b of the support member 11 connected to them are positioned so as to straddle the upper leg 52U of the motor mount 51L.

A suspension arm 71 is connected to the front 31a and rear 31b of the right strut tower 31R. A suspension arm 71 is also connected to the front 31a and rear 31b of the left strut tower 31L. The configuration of the suspension arm 71 and its surrounding components is the same for both left and right strut towers 31R, 31L, so below only the right side will be described and the description of the left side will be omitted.

As shown in Figures 5 and 6, the suspension arm 71 is an upper link of a double wishbone suspension that has a V-shape, and is also called an A-arm. The suspension arm 71 supports a wheel (not shown). A suspension strut 72 is disposed inside the V-shape of the suspension arm 71.

The front end 71A of the suspension arm 71 is connected to the front 31a of the strut tower 31R via a mounting bolt 74a. The rear end 71B of the suspension arm 71 is connected to the rear 31b of the strut tower 31R via a mounting bolt 74b. That is, both ends 71A and 71B of the suspension arm 71 are connected to the front 31a and rear 31b of the strut tower 31R, and the front 31a and rear 31b are connected via one suspension arm 71. The mounting bolts 74a and 74b are inserted into bushes (not shown) that are pressed into the ends 71A and 71B of the suspension arm 71. The mounting bolts 74a and 74b are located above the upper surfaces 34a of the brackets 34A and 34B, i.e., above the front connection point p1 and the rear connection point p2.

5, the front connection point p1 between the support member 11 and the strut tower 31R is located rearward of the front fixed point r1 of the suspension arm 71, more specifically, rearward of the front end of the front fixed point r1. The rear connection point p2 between the support member 11 and the strut tower 31R is located forward of the rear fixed point r2 of the suspension arm 71, more specifically, forward of the rear end of the rear fixed point r2. That is, the connection points p1 and p2 are located between the fixed points r1 and r2 of the suspension arm 71 in the vehicle fore-and-aft direction, more specifically, between the front end of the front fixed point r1 and the rear end of the rear fixed point r2. Here, the front fixed point r1 includes the mounting bolt 74a, and the rear fixed point r2 includes the mounting bolt 74b. The front end of the front fixing point r1 is the fastening point of the mounting bolt 74a on the front wall 38a of the housing 32 of the strut tower 31R, i.e., the center point of the through hole for the mounting bolt 74a provided in the front wall 38a. The rear end of the rear fixing point r2 is the fastening point of the mounting bolt 74b on the rear wall 38b of the housing 32 of the strut tower 31R, i.e., the center point of the through hole for the mounting bolt 74b provided in the rear wall 38b.

Two first reinforcing panels 91, 92 and one second reinforcing panel 93 are arranged side by side in the fore-and-aft direction of the vehicle inside the housing 32 of the strut tower 31R.

The first reinforcing panel 91 includes a first wall 91a, a second wall 91b, and a third wall 91c each extending substantially vertically, and a fourth wall 91d extending substantially horizontally. The first wall 91a extends along the vehicle width direction inner wall 32a of the housing 32 and is joined to the vehicle width direction inner wall 32a. The second wall 91b extends outward in the vehicle width direction from the front end edge 94b of the first wall 91a, extends along the front side wall 38a of the housing 32, and is joined to the front side wall 38a. The third wall 91c extends outward in the vehicle width direction from the rear end edge 94a of the first wall 91a and faces the second wall 91b in the vehicle front-rear direction. The fourth wall 91d extends outward in the vehicle width direction from the upper end of the first wall 91a, and is connected at the front and rear ends to the upper end edge of the second wall 91b and the upper end edge of the third wall 91c.

The first reinforcing panel 92 includes a first wall 92a, a second wall 92b, and a third wall 92c each extending substantially vertically, and a fourth wall 92d extending substantially horizontally. The first wall 92a extends along the vehicle width direction inner wall 32a of the housing 32 and is joined to the vehicle width direction inner wall 32a. The second wall 92b extends outward in the vehicle width direction from the rear end edge 95a of the first wall 92a, extends along the rear side wall 38b of the housing 32, and is joined to the rear side wall 38b. The third wall 92c extends outward in the vehicle width direction from the front end edge 95b of the first wall 92a and faces the second wall 92b in the vehicle front-rear direction. The fourth wall 92d extends outward in the vehicle width direction from the upper end edge of the first wall 92a, and is connected at its front and rear ends to the upper end edge of the second wall 92b and the upper end edge of the third wall 92c.

The second reinforcing panel 93 has a U-shaped cross section and includes a first wall 93a, a second wall 93b, and a third wall 93c, each of which extends in a generally vertical direction. The first wall 93a extends along the vehicle width direction inner wall 32a of the housing 32 and is joined to the vehicle width direction inner wall 32a. The second wall 93b extends outward in the vehicle width direction from the front end edge 96b of the first wall 93a, extends along the third wall 91c of the first reinforcing panel 91, and is joined to the third wall 91c. The third wall 93c extends outward in the vehicle width direction from the rear end edge 96a of the first wall 93a, extends along the third wall 92c of the first reinforcing panel 92, and is joined to the third wall 92c.

The tip 71A of the suspension arm 71 is housed inside the first reinforcing panel 91 so as to be rotatable around the axis of the mounting bolt 74a. The tip 71B of the suspension arm 71 is housed inside the first reinforcing panel 92 so as to be rotatable around the axis of the mounting bolt 74b. The first reinforcing panel 91, the front wall 38a of the housing 32, the second reinforcing panel 93, and the tip 71A of the suspension arm 71 are fastened together by the fastening device, the mounting bolt 74a. The first reinforcing panel 92, the rear wall 38b of the housing 32, the second reinforcing panel 93, and the tip 71B of the suspension arm 71 are fastened together by the fastening device, the mounting bolt 74b.

As shown in FIG. 5, the front end of the mounting bolt 74a inserted into the tip 71A of the suspension arm 71 is supported by the second wall 91b of the first reinforcing panel 91 and the front wall 38a of the housing 32. The rear end of the mounting bolt 74a is supported by the third wall 91c of the first reinforcing panel 91 and the second wall 93b of the second reinforcing panel 93.

The rear end of the mounting bolt 74b inserted into the tip 71B of the suspension arm 71 is supported by the second wall 92b of the first reinforcing panel 92 and the rear wall 38b of the housing 32. The front end of the mounting bolt 74b is supported by the third wall 92c of the first reinforcing panel 92 and the third wall 93c of the second reinforcing panel 93.

In this way, the first reinforcing panel 91 reinforces the front end of the front fixing point r1 of the suspension arm 71 and its vicinity, improving the support rigidity of the front end of the mounting bolt 74a. The first reinforcing panel 92 reinforces the rear end of the rear fixing point r2 of the suspension arm 71 and its vicinity, improving the support rigidity of the rear end of the mounting bolt 74b. The second reinforcing panel 93 reinforces the third wall 91c of the first reinforcing panel 91 to improve the support rigidity of the rear end of the mounting bolt 74a, and reinforces the third wall 92c of the first reinforcing panel 92 to improve the support rigidity of the front end of the mounting bolt 74b.

Also, as shown in FIG. 7, the upper leg 52U of the motor mount 51R is fastened to the vehicle width direction inner wall 32a of the housing 32 of the strut tower 31R and to the first wall 93a of the second reinforcing panel 93 (see FIG. 6) by fastening bolts 33, and is supported by them. In other words, the second reinforcing panel 93 reinforces the attachment point P1 of the motor mount 51R and its vicinity, improving the support rigidity of the motor mount 51R.

The second reinforcing panel 93 extends vertically inside the housing 32 of the strut tower 31R. The upper end of the second reinforcing panel 93 is located above the mounting bolts 74a and 74b. As shown in Figures 6 and 7, the lower end of the second reinforcing panel 93 is located below the front connection point p1 and the rear connection point p2, more specifically, below the upper surfaces 34a of the two brackets 34A and 34B.

The brackets 34A and 34B are joined to the housing 32 of the strut tower 31R as well as to the second reinforcing panel 93. The second reinforcing panel 93 also contributes to improving the support rigidity of the support member 11 via the brackets 34A and 34B.

In this embodiment, as shown in Figures 1, 3, and 4, the support member 11 is fixed to a cowl panel 44 located above the support member 11 via a support 14. The support 14 is L-shaped in a side view and has a first surface 14A and a second surface 14B. The first surface 14A is fastened to the connecting member 13 of the support member 11 by a bolt 45. An on-vehicle part 30 is mounted on the first surface 14A. The on-vehicle part 30 is, for example, a VDC (Vehicle Dynamics Control). The second surface 14B is fastened to a support piece 44A vertically installed in the center of the cowl panel 44 in the vehicle width direction by a bolt 46. The shape and constituent material of the support 14 are not limited to those shown in the figures.

The effects of the support structure S for vehicle-mounted components according to the embodiment will be explained.

(1) The support structure S includes a support member 11 having a mounting surface 11A between the strut towers 31R and 31L on which the vehicle-mounted components 15A to 15C are placed. The support member 11 is connected to each of the strut towers 31R and 31L, and a suspension arm 71 that supports the wheel is connected to the front part 31a and the rear part 31b of each of the strut towers 31R and 31L. That is, in the support structure S, the support member 11 is connected to the highly rigid strut towers 31R and 31L to which the suspension arm 71 is connected to the front part 31a and the rear part 31b. This makes it possible to suppress deformation of the mounting surface 11A of the support member 11 during a frontal collision, and to suppress the application of excessive force to the vehicle-mounted components (FL box, PCT heater, DC/DC converter, VDC, etc.).

(2) In the support structure S, the connection points p1 and p2 of the support member 11 with the strut towers 31R and 31L are located rearward of the front fixing point r1 of the suspension arm 71 connected to the front part 31a of the strut towers 31R and 31L. In addition, the connection points p1 and p2 of the support member 11 with the strut towers 31R and 31L are located forward of the rear fixing point r2 of the suspension arm 71 connected to the rear part 31b of the strut towers 31R and 31L. The area between the front fixing point r1 and the rear fixing point r2 of the strut towers 31R and 31L, more specifically the area between the front end of the front fixing point r1 and the rear end of the rear fixing point r2, has higher rigidity than the outside area. According to the support structure S, the connection points p1 and p2 are more reliably located in the area between the fixing points r1 and r2, so that deformation of the support surface 11A during a frontal collision can be further suppressed.

(3) In the support structure S, motor mounts 51R, 51L are attached to each of the strut towers 31R, 31L, which support the motor 20 for driving the vehicle, which is disposed below the support member 11. Therefore, the left and right strut towers 31L, 31R are connected to each other via the motor 20 and the motor mounts 51R, 51L, improving the rigidity of the portion of the strut towers 31R, 31L near the attachment point P1 of 31R, 32L. Also, in the support structure S, the motor mounts 51R, 51L are located between the front connection point p1 and the rear connection point p2 in each of the strut towers 31R, 31L. The area between the front connection point p1 and the rear connection point p2 in the strut towers 31R, 31L is reinforced by the motor mounts 51R, 51L, suppressing the crushing deformation of that area in the event of a frontal collision.

(4) In the support structure S, the support member 11 is fixed to the cowl panel 44 located above the support member 11 via the support 14, which further improves the rigidity of the support member 11 and further suppresses deformation of the support surface 11A during a frontal collision.

(5) In the support structure S, the suspension arm 71 connects the front portion 31a and the rear portion 31b of each of the strut towers 31R and 31L. This increases the rigidity of the strut towers 31R and 31L, and further suppresses deformation of the support surface 11A during a frontal collision.

(6) In the support structure S, a first reinforcing panel 91, 92 and a second reinforcing panel 93 are disposed inside the housing 32 of each of the strut towers 31R, 31L. The first reinforcing panels 91, 92 are disposed at the front portion 31a and rear portion 31b of each of the strut towers 31R, 31L, respectively, and are joined to the housing 32. The second reinforcing panel 93 is disposed between the first reinforcing panels 91, 92, and is joined to the first reinforcing panels 91, 92 and the housing 32. In addition, the first reinforcing panel 91 disposed at the front portion 31a, the front wall 38a of the housing 32, the second reinforcing panel 93, and the suspension arm 71 are fastened together by a mounting bolt 74a, which is a fastener. Furthermore, the first reinforcing panel 92 disposed on the rear portion 31b, the rear wall 38b of the housing 32, the second reinforcing panel 93, and the suspension arm 71 are fastened together by fastening bolts 74b. This improves the rigidity of the portion of the strut towers 31R, 31L that supports the suspension arm 71 and the vicinity thereof, further suppressing deformation of the mounting surface 11A of the support member 11 during a frontal collision.

(7) In the support structure S, the lower end of the second reinforcing panel 93 is located below the connection points p1, p2. This reinforces the connection points p1, p2 and their vicinity on the strut towers 31R, 31L, improving the support rigidity of the support member 11, and further suppressing deformation of the support surface 11A of the support member 11 during a frontal collision. Note that instead of or in addition to the second reinforcing panel 93, the lower end of the first reinforcing panel may be located below the connection points p1, p2. In this case as well, the same effect can be obtained.

(8) In the support structure S, the motor mounts 51R, 51L, the housing 32, and the second reinforcing panel 93 are fastened together by the fastening bolts 33. This improves the rigidity of the parts of the strut towers 31R, 31L that support the motor mounts 51R, 51L and their vicinity, further suppressing deformation of the mounting surface 11A of the support member 11 during a frontal collision.

(9) In the support structure S, the attachment point P1 of the motor mount 51R, 51L in each of the strut towers 31R, 31L is located rearward of the front connection point p1 and forward of the rear connection point p2. In addition, the upper ends of the motor mounts 51R, 51L are located higher than the front connection point p1 and the rear connection point p2. In other words, the motor mounts 51R, 51L are interposed between the front connection point p1 and the rear connection point p2. This further reinforces the area between the front connection point p1 and the rear connection point p2 in the strut towers 31R, 31L, so that deformation of the support surface 11A during a frontal collision can be more reliably suppressed.

The above embodiments are merely examples described to facilitate understanding of the invention. The technical scope of the invention is not limited to the specific technical matters disclosed in the above embodiments, but also includes various modifications, changes, and alternative technologies that can be easily derived therefrom.
