[0009] Hereinafter, with reference to the drawings, an example in which a support structure S for an on-vehicle component according to an embodiment is applied to a vehicle, such as an electric vehicle, that runs using an electric motor as a power source will be described. In each figure, FW indicates the front in the longitudinal direction of the vehicle, UP indicates the upper side in the vertical direction of the vehicle, and LH and RH indicate the left and right sides in the width direction of the vehicle, respectively. In the following description, the front, front side, rear side, 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 side, front side, rear side, rear side, upper side, upper side, lower side, lower side, left side, left side, right, and right side, respectively. Furthermore, components having the same functions as those already described will be designated by the same reference numerals, and their description will be omitted.

[0010] As shown in Figures 1 to 3, the support structure S includes a pair of strut towers 31R, 31L disposed on the left and right sides of the motor room MR. A motor 20 for driving the vehicle is disposed between the right strut tower 31R and the left strut tower 31L. Fixed shafts 22 are provided on left and right ends 21R, 21L of the motor 20, respectively, and extend outward in the vehicle width direction from the respective ends. The left and right fixed shafts 22 are supported by motor mounts 51R, 51L, respectively.

[0011] 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 its right end. The upper legs 52U are fastened to the left side surface 32L of the housing 32 of the strut tower 31R with bolts 33. The lower legs 52D are fastened to the left side surface 42L of the right front side member 41, which extends in the vehicle longitudinal direction at the lower right of the motor room MR, with bolts 35. The fastening points of the upper legs 52U and the lower legs 52D with the bolts 33 and 35 are the attachment points P1 of the motor mount 51L. Although not visible in the figure, the motor mount 51L similarly has two upper legs 52U and two lower legs 52D at its left end. The upper leg 52U is fastened to the right side surface of the housing 32 of the strut tower 31L by a bolt 33. Meanwhile, the lower leg 52D is fastened to the right side surface of the left front side member 41, which extends in the fore-and-aft direction of the vehicle 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, 35 are the attachment points P1 of the motor mount 51L.

[0012] 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 components can be placed. Various vehicle components 15A, 15B, and 15C (see FIG. 3 ) can be placed on mounting surface 11A. The vehicle component 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 ). The vehicle components 15B and 15C are, for example, a fusible link (FL) box, a PCT heater, a DC / DC converter, etc. The vehicle components to be mounted and supported on mounting surface 11A are not particularly limited, and various vehicle components can be selected.

[0013] The support member 11 is made of a metal panel material and has a generally rectangular, flat plate-like shape in 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, or the like. The constituent material of the support member 11 is also not particularly limited and may be, for example, a perforated metal, an expanded metal, a grating, or the like.

[0014] 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) that has an inverted U-shaped cross section and 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 with bolts 18.

[0015] 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 a front bracket 34A and a rear bracket 34B with bolts 37. The front bracket 34A protrudes leftward from the front portion 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 portion 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 with bolts 37. The front bracket 34A protrudes rightward from the front portion of the right side surface of the housing 32 of the left strut tower 31L. The rear bracket 34B protrudes rightward from the rear portion of the right side surface.

[0016] 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 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 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 will be 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 serve as the connection points.

[0017] The attachment point P1 of the motor mounts 51R, 51L is located rearward of the front connecting point p1 and forward of the rear connecting point p2. Furthermore, the attachment point P1 of the upper ends of the motor mounts 51R, 51L and the upper leg 52U is located above the front connecting point p1 and the rear connecting point p2, more specifically, above the upper surfaces 34a of the two brackets 34A, 34B. Furthermore, the attachment point P1 of the lower ends of the motor mounts 51R, 51L and the lower leg 52D is located below the front connecting point p1 and the rear connecting point p2, more specifically, below the upper surfaces 34a of the two brackets 34A, 34B. In other words, the front connecting point p1, the rear connecting point p2, and the right edge 11a of the support member 11 connected thereto are positioned so as to straddle the upper leg 52U of the motor mount 51R. Similarly, the front connecting point p1, the rear connecting point p2, and the left edge 11b of the support member 11 connected thereto are arranged so as to straddle the upper leg 52U of the motor mount 51L.

[0018] A suspension arm 71 is connected to the front section 31a and rear section 31b of the right strut tower 31R. A suspension arm 71 is also connected to the front section 31a and rear section 31b of the left strut tower 31L. Because the configuration of the suspension arm 71 and its surrounding components is the same for both strut towers 31R, 31L, only the right side will be described below, and the description of the left side will be omitted.

[0019] 5 and 6, the suspension arm 71 is a V-shaped upper link of a double wishbone suspension, 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.

[0020] The front end 71A of the suspension arm 71 is connected to the front portion 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 portion 31b of the strut tower 31R via a mounting bolt 74b. That is, both end portions 71A, 71B of the suspension arm 71 are connected to the front portion 31a and rear portion 31b of the strut tower 31R, and the front portion 31a and rear portion 31b are connected via a single suspension arm 71. The mounting bolts 74a and 74b are inserted into bushings (not shown) press-fitted into the end portions 71A, 71B of the suspension arm 71. The mounting bolts 74a and 74b are located above the upper surfaces 34a of the brackets 34A, 34B, i.e., above the front connecting point p1 and the rear connecting point p2.

[0021] As shown in Figure 5, the front connection point p1 between the support member 11 and 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 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, connection points p1 and p2 are located between the fixed points r1 and r2 of the suspension arm 71 in the vehicle longitudinal 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.

[0022] Two first reinforcing panels 91, 92 and one second reinforcing panel 93 are provided inside the housing 32 of the strut tower 31R, aligned in the vehicle front-rear direction.

[0023] 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 a 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 a 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 its front and rear ends to the upper end edges of the second wall 91b and the third wall 91c.

[0024] The first reinforcing panel 92 includes a first wall 92a, a second wall 92b, and a third wall 92c, each extending generally vertically, and a fourth wall 92d extending generally 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 a 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 a 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 edges of the second wall 92b and the third wall 92c.

[0025] 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 extending substantially vertically. 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 a 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 a 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.

[0026] The tip portion 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 portion 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 portion 71A of the suspension arm 71 are fastened together by the mounting bolt 74a, which is a fastener. The first reinforcing panel 92, the rear wall 38b of the housing 32, the second reinforcing panel 93, and the tip portion 71B of the suspension arm 71 are fastened together by the mounting bolt 74b, which is a fastener.

[0027] 5, the front end of the mounting bolt 74a inserted into the tip portion 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. In addition, 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.

[0028] The rear end of the mounting bolt 74b inserted into the tip portion 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.

[0029] 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. Furthermore, 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.

[0030] 7, upper leg 52U of motor mount 51R is fastened to and supported by vehicle width direction inner wall 32a of housing 32 of strut tower 31R and a first wall 93a (see FIG. 6) of second reinforcing panel 93 using fasteners such as bolts 33. In other words, second reinforcing panel 93 reinforces attachment point P1 of motor mount 51R and the vicinity thereof, improving the support rigidity of motor mount 51R.

[0031] 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. The lower end of the second reinforcing panel 93 is located below the front connecting point p1 and the rear connecting point p2, more specifically, below the upper surfaces 34a of the two brackets 34A and 34B, as shown in Figures 6 and 7 .

[0032] The brackets 34A, 34B are joined not only to the housing 32 of the strut tower 31R but also 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, 34B.

[0033] In this embodiment, as shown in FIGS. 1 , 3 , and 4 , the support member 11 is fixed to a cowl panel 44 located above the support member 11 via a support fixture 14. The support fixture 14 is L-shaped in a side view and includes 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 with a bolt 45. An on-vehicle component 30 is mounted on the first surface 14A. The on-vehicle component 30 is, for example, a vehicle dynamics control (VDC). The second surface 14B is fastened to a support piece 44A extending vertically from the center of the cowl panel 44 in the vehicle width direction with a bolt 46. Note that the shape and constituent material of the support fixture 14 are not limited to those shown in the drawings.

[0034] The effects of the support structure S for an in-vehicle component according to the embodiment will be described.

[0035] (1) The support structure S includes a support member 11 having a mounting surface 11A between strut towers 31R and 31L on which on-vehicle components 15A to 15C are placed. The support member 11 is coupled to each of the strut towers 31R and 31L, and suspension arms 71 that support the wheels are connected to the front and rear portions 31a and 31b of each of the strut towers 31R and 31L. That is, in the support structure S, the support member 11 is coupled to the highly rigid strut towers 31R and 31L, each having a front and rear portion 31a and 31b to which the suspension arms 71 are connected. This prevents deformation of the mounting surface 11A of the support member 11 during a frontal collision, thereby preventing excessive force from being applied to on-vehicle components (FL box, PCT heater, DC / DC converter, VDC, etc.).

[0036] (2) In the support structure S, the connection points p1 and p2 of the support member 11 to the strut towers 31R and 31L are located rearward of the front fixing point r1 of the suspension arm 71 connected to the front portion 31a of the strut towers 31R and 31L. Furthermore, the connection points p1 and p2 of the support member 11 to the strut towers 31R and 31L are located forward of the rear fixing point r2 of the suspension arm 71 connected to the rear portion 31b of the strut towers 31R and 31L. The region of the strut towers 31R and 31L between the front fixing point r1 and the rear fixing point r2, more specifically, the region 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 outer region. With the support structure S, the connection points p1 and p2 are more reliably located in the region between the fixing points r1 and r2, further suppressing deformation of the support surface 11A during a frontal collision.

[0037] (3) In the support structure S, motor mounts 51R, 51L are attached to each of the strut towers 31R, 31L. The motor mounts 51R, 51L support the vehicle drive motor 20, which is located 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 portions of the strut towers 31R, 31L near the attachment points P1 of the strut towers 31R, 31L. Furthermore, in the support structure S, the motor mounts 51R, 51L are located on each of the strut towers 31R, 31L between the front attachment point p1 and the rear attachment point p2. The motor mounts 51R, 51L reinforce the area between the front attachment point p1 and the rear attachment point p2 of the strut towers 31R, 31L, reducing crushing deformation in the event of a frontal collision.

[0038] (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 fixture 14, which further improves the rigidity of the support member 11 and further suppresses deformation of the support surface 11A during a frontal collision.

[0039] (5) In the support structure S, the suspension arm 71 connects the front portion 31a and the rear portion 31b of each strut tower 31R, 31L. This increases the rigidity of the strut towers 31R, 31L, and further reduces deformation of the support surface 11A during a frontal collision.

[0040] (6) In the support structure S, first reinforcing panels 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. The first reinforcing panel 91 disposed at the front portion 31a, the front side wall 38a of the housing 32, the second reinforcing panel 93, and the suspension arm 71 are fastened together by mounting bolts 74a, which serve as fasteners. Furthermore, the first reinforcing panel 92 disposed in 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, which improve the rigidity of the portions of the strut towers 31R, 31L that support the suspension arm 71 and the vicinity thereof, thereby further suppressing deformation of the mounting surface 11A of the support member 11 during a frontal collision.

[0041] (7) In the support structure S, the lower end of the second reinforcing panel 93 is located below the connecting points p1 and p2. This reinforces the connecting points p1 and p2 and their vicinity on the strut towers 31R and 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 connecting points p1 and p2. In this case, the same effect can be achieved.

[0042] (8) In the support structure S, the motor mounts 51R, 51L, the housing 32, and the second reinforcing panel 93 are fastened together by fasteners, i.e., bolts 33. This improves the rigidity of the portions of the strut towers 31R, 31L that support the motor mounts 51R, 51L and the vicinity thereof, thereby further suppressing deformation of the mounting surface 11A of the support member 11 during a frontal collision.

[0043] (9) In the support structure S, the attachment point P1 of the motor mount 51R, 51L of each strut tower 31R, 31L is located rearward of the front attachment point p1 and forward of the rear attachment point p2. The upper ends of the motor mounts 51R, 51L are located higher than the front attachment point p1 and the rear attachment point p2. In other words, the motor mounts 51R, 51L are located between the front attachment point p1 and the rear attachment point p2. This further reinforces the area of ​​the strut towers 31R, 31L between the front attachment point p1 and the rear attachment point p2, thereby more reliably suppressing deformation of the support surface 11A during a frontal collision.

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