Further, in each drawing, the illustration of parts is appropriately omitted for convenience of explanation.

[0039] As Figure 1As shown, the front part of the vehicle body with the engine compartment includes: a pair of left and right front side frames 11; a pair of left and right bumper beam supports 12; a bumper beam 13; a pair of left and right subframes 14; and a pair of left and right subframe support parts 15, etc.

[0040] A pair of left and right front side brackets 11 are respectively installed on the left and right sides of the vehicle width direction, extending towards the front and rear of the vehicle body, and have a mirror-symmetrical shape. These left and right pairs of front side brackets 11 are respectively connected to the left and right rear parts of the bumper 13 via bumper beam brackets 12 installed at the front of the front side brackets 11.

[0041] like Figure 1 As shown by the middle arrow, the left and right front side frames 11 are respectively connected to the subframe 14 via the subframe support portion 15, which extends downward from the front end of the front side frame 11.

[0042] The left and right pairs of bumper beam brackets 12 are components that fix the bumper 13 to the front end of the left and right pairs of front side brackets 11, and have a mirror-symmetrical shape. These left and right pairs of bumper beam brackets 12 are respectively fixed to the front end of the front side brackets 11 and to the left and right rear parts of the bumper 13.

[0043] The bumper beam 13 is positioned at the front of the front structure 1 of the vehicle body, extending in the direction of vehicle width. The bumper beam 13 is fixed to the bumper beam bracket 12, thereby connecting to a pair of left and right front side brackets 11, the bumper beam bracket 12 being located at the front end of each of the left and right front side brackets 11.

[0044] The subframe 14 is positioned lower than the front side frame 11. The subframe 14 is connected to the front side frame 11 via a subframe support 15, which extends downward from the front end of the front side frame 11.

[0045] The left and right subframe support parts 15 are components that connect the subframe 14 to the front side frame 11 and the bumper beam bracket 12, respectively, and have a mirror-symmetrical shape. These left and right subframe support parts 15 are fixed to the front end of the front side frame 11 and to the lower end of the bumper beam bracket 12.

[0046] Next, the details of the battery mounting support structure 30 will be explained. For example... Figure 6 As shown, the battery mounting support structure 30 includes: a rear reinforcing bracket 31, which is provided as an independent component; a rear support foot body 32; a connecting component 33; and a front reinforcing bracket 35 (see reference). Figure 3 , Figure 4 , Figure 9and a front support leg 34, which are disposed in order toward the front along a portion near the front end of the front end side frame 11 on the left side of the vehicle body. As shown in Figure 10 The battery B is placed and supported on the rear support leg main body 32 and the front support leg 34 in a positional relationship in which the front support leg 34 is disposed near the center of gravity BG of the battery B.

[0047] More specifically, as shown in Figure 6 The rear support leg main body 32 has a battery mounting surface 321 on which the battery B is placed and supported, a battery locking piece 322 which extends in a triangular shape upward from a central portion of one end edge of the battery mounting surface 321, and a support wall 323 which extends downward from the other end edge of the battery mounting surface 321. A locking hole 3221 is formed in the battery locking piece 322, and the lower portion of the locking rod 41 (see FIG. 2) is locked in the locking hole 3221. Figure 10

[0048] The upper portion of the locking rod 41 is connected to one end portion of a pressing plate 42 which presses the battery B from the upper side. In this way, as shown in Figure 10 The battery B is mounted in a manner in which the length direction of the battery B intersects the front-rear direction at an angle of about 45°. Therefore, the battery mounting surface 321 and the battery mounting surface 341 described later are disposed in a manner in which they intersect the front end portion of the front end side frame 11.

[0049] As shown in Figure 3 A longitudinal reinforcing rib 3231 is provided on the support wall 323. The longitudinal reinforcing rib 3231 is formed in a plurality on the support wall 323 along the up-down direction from the upper end to the lower end of the support wall 323. As shown in Figure 8 In a plan view, the support wall 323 has an inclined portion 3233 which has an inclined positional relationship with respect to the front-rear direction and an orthogonal portion 3234 which is orthogonal to the front-rear direction, and has a plate shape which is bent by the inclined portion 3233 and the orthogonal portion 3234.

[0050] As shown in Figure 6 The rear reinforcing bracket 31 is composed of a plate-shaped member which is integrally formed and bent in an L shape to have an upper surface 311 and a side surface 312. A plate-shaped front side flange 313 which is integrally formed with the upper surface 311 and the side surface 312 and is bent from the upper surface 311 and the side surface 312 is provided at an end edge on the front side from the upper surface 311 to the side surface 312, the front side flange 313 protruding in a direction opposite to the direction in which the L shape is bent and extending in a manner in which it is distanced from the side surface 112 of the front end side frame 11 toward the vehicle width direction. In addition, a plate-shaped rear side flange 314 which is integrally formed with the upper surface 311 and the side surface 312 is provided at an end edge on the rear side from the upper surface 311 to the side surface 312, the rear side flange 314 protruding in a direction opposite to the direction in which the L shape is bent. ​

[0051] like Figure 7 As shown, the upper surface 311 of the rear reinforcing bracket 31 is fixed by engaging with the upper surface 111 of the front side bracket 11. The side surface 312 of the rear reinforcing bracket 31 is fixed by engaging with the side surface 112 of the front side bracket 11. The front flange 313 of the rear reinforcing bracket 31 abuts against the lower part of the orthogonal portion 3234 constituting the rear support leg body 32 (see reference). Figure 7 They are fixed by overlapping and combining.

[0052] Thus, the rear support leg body 32 is supported by the upper surface 111 and side surface 112 of the front side frame 11 via the rear reinforcing bracket 31. Therefore, the rear support leg, which is composed of the rear support leg body 32 and the rear reinforcing bracket 31, is supported by the upper surface 111 and side surface 112 of the front side frame 11 on the rear side of the connecting member 33.

[0053] like Figure 6 As shown, the connecting member 33 has an upper surface 331, a rear flange 332, and a front flange 333, and connects the rear support leg body 32 and the front support leg 34. The upper surface 331 is positioned at a lower position than the battery mounting surface 321 and the battery mounting surface 341, and as shown... Figure 5 As shown, the upper surface 331 has a gradually expanding shape extending forward along the left-right direction, which is the width of the vehicle. Figure 8 As shown, a wire harness H is arranged above the upper surface 331 of the connecting component 33. The wire harness H has multiple branch points DP that branch into each other midway and is used to supply power from the battery B, etc.

[0054] In addition, such as Figure 5 As shown, a plurality of front and rear reinforcing ribs 3311 extending in the front-rear direction are formed on the upper surface 331 of the connecting member 33. The rear ends of the front and rear reinforcing ribs 3311 have a positional relationship consistent with the longitudinal reinforcing ribs 3231 of the support wall 323, thereby, as Figure 5 As shown, in the plan view, the longitudinal reinforcing rib 3231 is continuous with the front and rear reinforcing ribs 3311. Figure 9 As shown, a portion of the connecting member 33 having an upper surface 331 is fixed by engaging with the upper surface 111 of the front side frame 11, and is fixed by engaging with the upper surface 351 of the front reinforcing bracket 35 (described later).

[0055] Additionally, the rear flange 332 has a plate-like portion that protrudes upward from the rear end edge of the upper surface 331 and is located opposite the front flange 333, such as... Figure 8 As shown, it is arranged in a positional relationship that opposes and abuts against the inclined portion 3233 and the orthogonal portion 3234 of the connecting member 33. The front flange 333 has a plate-like shape that protrudes upward from the front end edge of the upper surface 331, such as Figure 8As shown, it is configured to face and abut against the connecting part of the front support leg 34 with the opposing surface 3435.

[0056] like Figure 3 As shown, the front reinforcing bracket 35 is composed of a plate-like component, which is integrally formed and bent into an L-shape, having an upper surface 351 and a side surface 352. The upper surface 351 extends away from the side surface 112 of the front side bracket 11 in the vehicle width direction. The side surface 352 is fixed by engaging with the side surface 112 of the front side bracket 11. At the front edge from the upper surface 351 to the side surface 352, a plate-like front sidewall 353 is integrally formed with the upper surface 351 and the side surface 352, and the front sidewall 353 protrudes in the same direction as the L-shape. The front sidewall 353 of the front reinforcing bracket 35 is fixed by engaging with the opposing surface 3435 of the connecting portion of the front support leg 34. Thus, the front support leg 34 is fixed by engaging with the side surface 112 of the front side bracket 11.

[0057] The front support leg 34 has: a battery mounting surface 341 for mounting and supporting the battery B; a battery locking piece 342 extending upward in a triangular shape near the center of one end edge of the battery mounting surface 341; a support wall 343 extending downward from the other end edge of the battery mounting surface 341; and an abutment surface 3436 formed at the lower end of the support wall 343 as a plate along the upper surface 111 and the side surface 112 of the front side frame 11.

[0058] A locking hole 3421 is formed on the battery locking piece 342, and the locking rod 43 (see reference) Figure 10 The lower part of the locking rod 43 is locked in the locking hole 3421. The upper part of the locking rod 43 is connected to the other end of the pressure plate 42 that presses down on the battery B from above.

[0059] like Figure 5 As shown, longitudinal reinforcing ribs 3431 are provided on the support wall 343. The longitudinal reinforcing ribs 3431 extend vertically from the upper end to the lower end of the support wall 343, that is, from the battery mounting surface 341 to the abutment surface 3436, thus forming multiple ribs. For example... Figure 5 As shown, in the plan view, the support wall 343 has a positional relationship opposite to the support wall 323 relative to the front-rear direction. Figure 2 , Figure 4 , Figure 9 As shown, the abutment surfaces 3436 are fixed by engaging with the upper surface 111 and the side surface 112 of the front side frame 11, respectively. Thus, the front support leg 34 is supported on the upper surface 111 and the side surface 112 of the front side frame 11 at the front of the connecting member 33.

[0060] According to this embodiment, the following effects are achieved.

[0061] In the present embodiment, there are the front support leg 34 and the rear support leg (the rear reinforcement bracket 31, the rear support leg body 32) that support the battery B, and the link member 33 that links the front support leg 34 and the rear support leg body 32, and the front support leg 34 and the rear support leg (the rear reinforcement bracket 31, the rear support leg body 32) are supported by the upper surface 111 and the side surface 112 of the front end side frame 11 in front and back of the link member 33.

[0062] Thus, the front support leg 34 and the rear support leg (the rear support bracket 31, the rear support leg body 32) that support the battery B are supported by the upper surface 111 and the side surface 112 of the front end side frame 11 in front and back of the link member 33, and therefore, it is not limited to be arranged on the inner side of the front end side frame 11, but it is possible to stably support the front support leg 34 and the rear support leg (the rear support bracket 31, the rear support leg body 32) via the link member 33 and the front end side frame 11, and it is possible to achieve weight reduction.

[0063] In addition, in the present embodiment, the front support leg 34 and the rear support leg (the rear reinforcement bracket 31, the rear support leg body 32) each have the battery mounting surface 341, the battery mounting surface 321, the support wall 343, the support wall 323, the abutting surface 3436, and the abutting surface 3236. Thus, it is possible to easily form the battery mounting surface 341, the battery mounting surface 321, the support wall 343, the support wall 323, the abutting surface 3436, and the abutting surface 3236 by press working or the like.

[0064] In addition, in the present embodiment, the battery mounting surface 341 is provided on either one of the front support leg 34 and the rear support leg (the rear reinforcement bracket 31, the rear support leg body 32), and the longitudinal reinforcement rib 3431 and the longitudinal reinforcement rib 3231 that extend in the vertical direction from the battery mounting surface 321 to the abutting surface 3436 and the abutting surface 3236. Thus, it is possible to improve the support strength of the front support leg 34 and the rear support leg body 32.

[0065] In addition, in the present embodiment, the link member 33 has a pair of flanges (the front side flange 333, the rear side flange 332) that are bent so as to face each other with respect to the front support leg 34 and the rear support leg 32. Thus, it is possible to firmly join the link member 33 with the front support leg 34 and the rear support leg body 32.

[0066] In addition, in the present embodiment, the longitudinal reinforcement rib 3431 and the longitudinal reinforcement rib 3231 are continuous with the front-rear reinforcement rib 3311 that extends in the front-rear direction of the link member 33. Thus, it is possible to improve the support strength of the front support leg 34 and the rear support leg body 32, and thereby suppress deformation of the link member 33.

[0067] In addition, in the present embodiment, the rear support leg main body 32 is joined to the upper surface 111 and the side surface 112 of the front end side frame 11 via the rear reinforcement bracket 31 provided as a separate member. Thus, even if the longitudinal reinforcement rib 3231 of the rear support leg main body 32 is undercut, since the rear reinforcement bracket 31 is formed of a different member from the rear support leg main body 32, it can be easily formed, and the battery B can be supported.

[0068] In addition, in the present embodiment, the inclined portion 3233 of the support wall 323 of the rear support leg main body 32 is formed obliquely with respect to the front-rear direction in a plan view, and the link member 33 is formed to be lower than the battery mounting surface 341, the battery mounting surface 321, and gradually expand in the front direction. Thus, branching of the wire harness H can be performed below the battery mounting surface 341, the battery mounting surface 321.

[0069] In addition, in the present embodiment, the front support leg 34 is joined to the side surface 112 of the front end side frame 11 via the front reinforcement bracket 35 provided as a separate member. Thus, even if the longitudinal reinforcement rib 3431 of the front support leg 34 is undercut, since the front reinforcement bracket 35 is formed of a different member from the front support leg 34, it can be easily formed.

[0070] In addition, in the present embodiment, the link member 33 extends along the vehicle width direction and is joined to the upper surface 111 of the front end side frame 11 and the upper surface 351 of the front reinforcement bracket 35. Thus, the link member 33 is joined to the side surface 112 via the upper surface 111 of the front end side frame 11 and the front reinforcement bracket 35, and thus the front support leg 34 and the rear support leg main body 32 can be more firmly supported.

[0071] In addition, in the present embodiment, the rear support leg main body 32 is joined to the upper surface 111 and the side surface 112 of the front end side frame 11 via the rear reinforcement bracket 31 provided as a separate member, and the front reinforcement bracket 35 and the rear reinforcement bracket 31 respectively extend in a manner that moves away from the side surface 112 of the front end side frame 11 toward the vehicle width direction.

[0072] Thus, even if the rear reinforcement bracket 31 is fixed to the front end side frame 11, thereby biasing the front reinforcement bracket 35 to the inner side of the front end side frame 11, the battery B can be prevented from tilting. Furthermore, since the reinforcement brackets (the front reinforcement bracket 35, the rear reinforcement bracket 31) are divided front-rear, weight reduction can be achieved.

[0073] In addition, in the present embodiment, the battery mounting surface 341, the battery mounting surface 321 are disposed in a manner that intersects the front end portion of the front end side frame 11. Thus, the battery B can be stably supported by the front end of the firm front end side frame 11.

[0074] Furthermore, in this embodiment, a front support foot 34 is provided near the center of gravity BG of battery B. Therefore, even if the center of gravity BG of battery B flies outward from the front side frame 11, instability due to vibration caused by external forces can be prevented.

[0075] In addition, in this embodiment, the rear support leg body 32 is bent and connected to the rear reinforcing bracket 31 in a manner that overlaps with it. As a result, the rear support leg body 32 can be connected to the robust front side frame 11 via the rear reinforcing bracket 31, and can be bent to increase the battery mounting surface 321.

[0076] This invention is not limited to the above-described embodiments. Modifications and improvements that can achieve the purpose of this invention are included in this invention.

[0077] For example, in this embodiment, such as Figure 10 As shown, the battery B is supported at an angle of approximately 45° relative to the longitudinal direction, but this configuration is not limited to this. For example, the arrangement of the battery retaining piece 322 extending upward in a triangular shape on the rear support leg body 32 can be appropriately modified, or the arrangement of the battery retaining piece 342 extending upward in a triangular shape on the front support leg 34 can be appropriately modified, thereby achieving the desired effect. Figure 11 As shown, battery B is supported in such a way that its length is perpendicular to the width direction of the vehicle. Figure 11 This is an explanatory diagram showing a case where the battery B is mounted on the battery mounting support structure 30 of the vehicle in a positional relationship different from that described in the above embodiment.

[0078] In addition, a longitudinal reinforcing rib 3231 is provided on the support wall 323 of the rear support leg body 32, and a longitudinal reinforcing rib 3431 is provided on the support wall 343 of the front support leg 34, but the structure is not limited to this. As long as a longitudinal reinforcing rib extending in the vertical direction from the battery mounting surface to the contact surface is provided on either the front support leg or the rear support leg, it is sufficient.

[0079] In addition, such as Figure 5 As shown, the upper surface 331 of the connecting member 33 has a gradually expanding shape extending in the rearward direction along the left-right direction, which is the vehicle width direction, but is not limited to this structure. The connecting member can be formed to gradually expand in at least one direction, the forward direction and the rearward direction.
