[0039] In the diagrams, arrow Fr indicates the forward direction of the vehicle body, arrow Rr indicates the rearward direction, arrow Up indicates the upward direction of the vehicle body, arrow L indicates the leftward direction in the width direction, and arrow R indicates the rightward direction in the width direction. Additionally, for ease of explanation, some parts have been omitted from the diagrams.

[0040] like Figure 1As shown, the front of the vehicle body, which includes the engine compartment, has a pair of left and right front side frames 11. For ease of explanation, only the left front side frame 11 is shown. The pair of left and right front side frames 11 are respectively positioned on the left and right sides in the vehicle width direction, extending in the longitudinal direction of the vehicle body, and have a mirror-symmetrical shape. These left and right front side frames 11 are connected to the left and right rear parts of a bumper beam (not shown) via bumper beam brackets (not shown) located at the front end of each front side frame 11.

[0041] A front bulkhead (not shown) is provided behind the front side frame 11, the bulkhead being configured to face forward and rearward and separating the engine compartment from the passenger compartment. A brake master cylinder assembly 12 is mounted on the front side of the bulkhead. The brake master cylinder assembly 12 has a base end fixed to the front surface of the bulkhead and protrudes forward from the base end.

[0042] Next, the battery rotation structure 30 of the vehicle will be described in detail. The battery rotation structure 30 includes: battery B (reference) Figure 4 (etc.), set as separate and independent components; battery support plate 31 (reference) Figure 1 (etc.), having battery support surfaces 3110, 3120, 3130 (reference) Figure 6 (etc.) and battery locking pieces 3111, 3121; locking rods 41, 43 (for reference) Figure 4 (etc.); pressing plate 42; and mounting base 50 (reference) Figure 1 wait).

[0043] The mounting base 50 is fixed to the upper surface 111 of the front side frame 11 using bolts. For example... Figure 1 , Figure 2 As shown, the mounting base 50 has a mountain-shaped profile, with its length in the longitudinal direction decreasing upwards from the base of the mounting base 50, which is fixed to the upper surface 111 of the front side frame 11. Approximately one-third of the way down from the upper end of the mounting base 50, a reinforcing bracket 35 supporting the battery support plate 31 is bolted and fixed to it (see reference). Figure 2 The lower end of (etc.).

[0044] A rear support leg 36 is provided on the side 112 of the front side frame 11, which is located further rearward than the mounting base 50. The rear support leg 36 extends diagonally upward, moving towards the inner side of the vehicle body (right side) in the width direction as it approaches the upper part of the side 112 of the front side frame 11. The lower end of the rear support leg 36 is bolted to the side 112 of the front side frame 11. The lower end of the upper battery support bracket 37 is fixed to the upper end surface 361 of the rear support leg 36. Furthermore, a support plate fixing surface 362 (see reference) is provided on the front side of the upper end of the rear support leg 36, which is lower than the upper end surface of the rear support leg 36. Figure 5 (etc.), the rear end of the battery support plate 31 is bolted and fixed on the support plate fixing surface 362.

[0045] like Figure 5 As shown, the upper battery support bracket 37 is composed of a plate-shaped member with an approximately L-shaped cross-section orthogonal to the length direction of the upper battery support bracket 37. The lower end of the upper battery support bracket 37, with an approximately L-shaped cross-section, one side of the upper battery support bracket 37 (rear battery support surface 371) is joined and fixed to the upper end surface 361 of the rear support leg 36.

[0046] like Figure 3 As shown, the upper battery support bracket 37 extends to the left of the vehicle body from its lower end, which is fixed to the upper end of the rear support leg 36, and bends towards the front of the vehicle body above the upper surface 111 of the front side frame 11. Furthermore, at the portion of the upper battery support bracket 37 that forms the bend 376 further forward than this bend, at the rear end of the mounting base 50, the other side (the upper end of the abutment surface 372) of the approximately L-shaped upper battery support bracket 37 is bolted to a rigid member 15, which is fixed to the shock absorber housing 14 to improve rigidity. Therefore, the portion of the upper battery support bracket 37 that forms the bend 376 is positioned between the brake master cylinder device 12, which is an engine mounting component, and the mounting base 50.

[0047] like Figure 3 As shown, the battery support plate 31 is formed into a plate shape with a "コ" shape when viewed from above, and has a left support plate portion 311, a right support plate portion 312, and a connecting plate portion 313 connecting them. Therefore, at the center of them, that is, at the center of the battery support surfaces 3110, 3120, and 3130 described below, an opening 3101 is formed that is surrounded by them and extends through the battery support plate 31 in the vertical direction.

[0048] The upper surfaces of the left support plate portion 311, the right support plate portion 312, and the connecting plate portion 313 constitute battery support surfaces 3110, 3120, and 3130 for mounting and supporting the battery B. Behind the battery B supported by the battery support surfaces 3110, 3120, and 3130, a brake master cylinder device 12 is arranged, and the contact surface 372 of the battery B and the upper battery support bracket 37 is opposite to the brake master cylinder device 12.

[0049] like Figure 6 As shown, the left end edge of the central portion of the left support plate portion 311 in the longitudinal direction (i.e., the front-to-back direction) has a battery retaining piece 3111 extending upward in a triangular shape. A left end edge plate portion 3113 extends from the battery retaining piece 3111 in the front and back directions. Multiple cutouts 3115 are formed on the end edge plate portion 3113 in the front and back directions of the battery retaining piece 3111. Furthermore, multiple cutouts 3116 are also formed on the right end edge of the left support plate portion 3111. The cutouts 3115 and 3116 at the very end are formed at both ends of the groove portion 3114 in the left-to-right direction.

[0050] A locking hole 3112 is formed in the battery locking piece 3111, and a locking rod 43 (reference) is locked in the locking hole 3112. Figure 4 The lower part of the locking lever 43 is connected to the left end of the pressing plate 42 that presses the battery B from the top.

[0051] like Figure 6 As shown, the rear end of the left support plate portion 311 has an inclined portion 3117 and a vertical wall portion 3118. The inclined portion 3117 is inclined in a manner that it descends downwards as it moves towards the rear. Therefore, as Figure 6 As shown, the left support plate portion 311 is bent into a mountain shape. The lower end of the vertical wall portion 3118 is integrally connected to the lower end of the inclined portion 3117, and the connection between the vertical wall portion 3118 and the inclined portion 3117 forms a groove portion 3114 with an approximately L-shaped cross-section. The vertical wall portion 3118 is bolted to and fixed to the support plate fixing surface 362.

[0052] At the right end edge of the central part of the right support plate portion 312 in the longitudinal direction, i.e., the front-to-back direction, such as Figure 6 As shown, a battery retaining piece 3121 is fixed thereon. The battery retaining piece 3121 is composed of a component different from the right-side support plate portion 312 and extends upwards in a triangular shape. A retaining hole 3122 is formed in the battery retaining piece 3121, and a retaining rod 41 (see reference) is retained in the retaining hole 3122. Figure 4The lower part of the battery B is connected to the upper part of the locking lever 41. The upper part of the locking lever 41 is connected to the right end of the pressing plate 42 that presses the battery B from the top. A cutout 3126 is formed in the right support plate portion 312 where the battery locking piece 3121 is fixed, which is recessed toward the left support plate portion 311.

[0053] The rear end of the right-side support plate portion 312 has an inclined portion 3127 and a vertical wall portion 3128. The inclined portion 3127 is inclined in a manner that it descends downwards as it moves rearwards. Therefore, as Figure 6 As shown, although not as pronounced as the left support plate portion 311, the right support plate portion 312 is also slightly bent into a mountain shape. The lower end of the vertical wall portion 3128 is integrally connected to the lower end of the inclined portion 3127, and the connection between the vertical wall portion 3128 and the inclined portion 3127 forms a groove portion 3124 with an approximately L-shaped cross-section. Figure 6 As shown, the vertical wall portion 3128 is bolted to and fixed to the support plate fixing surface 362.

[0054] Next, the operation of the vehicle's battery rotation structure during a frontal collision will be explained. Figure 7 This is an enlarged side view showing the state of the brake master cylinder device 12 before it collides with the vehicle's battery rotation structure 30. Figure 8 This is an enlarged side view showing the state of the brake master cylinder device 12 after it collides with the vehicle's battery rotation structure 30.

[0055] like Figure 7 As shown, at the moment before the frontal collision of the vehicle, the brake master cylinder device 12 is positioned further rearward than the contact surface 372 of the upper battery support bracket 37 of the vehicle's battery rotation structure 30, and is spaced apart from the contact surface 372.

[0056] Next, during a frontal collision, the front side frame 11 moves rearward. Therefore, since the reinforcing bracket 35 supporting the front of the battery support plate 31 is fixed on the mounting base 50 fixed to the front side frame 1, the battery B supported by the battery support plate 31 moves rearward relative to the brake master cylinder device 12 together with the front of the battery support plate 31.

[0057] Consequently, the left support plate portion 311 and the right support plate portion 312 of the battery support plate 31, which is bent into a mountain shape when viewed from the side, gradually deform, and the mountain shape becomes steeper. As a result, the battery B is displaced, and the portion further back than the center of the battery B is lifted upward relative to the front end of the battery B.

[0058] Then, if the contact surface 372 collides with the brake master cylinder device 12, then as Figure 8As shown, when viewed from the side, the left support plate portion 311 and the right support plate portion 312 of the mountain-shaped battery support plate 31 are further deformed, making the mountain shape steeper. Therefore, in the battery B supported by the battery support plate 31, the front end rotates downwards and the rear end rises upwards, as... Figure 8 As shown, battery B rotates forward and downward with the pressing plate 42 as the fulcrum.

[0059] According to this embodiment, the following effects are achieved.

[0060] In this embodiment, the vehicle's battery rotation structure 30 includes: a battery B, which is opposite to the brake master cylinder device 12, which is an engine-mounted component; a battery support plate 31, which has a battery support surface that can deform into a mountain shape in the event of a frontal collision; a pair of battery locking pieces 3111 and 3121, which are disposed on two sides of the battery support surface in the front-rear direction center; a pair of locking rods 43 and 41, which are locked in the locking holes 3112 and 3122 of the pair of battery locking pieces 3111 and 3121; and a pressing plate 42, which is connected to the upper part of the pair of locking rods 43 and 41.

[0061] Therefore, during a frontal collision, the master brake cylinder device 12 moves rearward and pushes the battery B backward. At this time, the front part of the battery support plate 31, which has a battery support surface, lifts the battery B. As a result, the lower part of the battery fixing hook at the bottom of the locking rods 41 and 43 deforms the battery locking pieces 3111 and 3121. Then, the battery B rotates around the pressing plate 42 at the top of the locking rods 41 and 43 as a fulcrum. Therefore, the master brake cylinder device 12 can suppress the movement of the battery B to the side of the vehicle compartment, i.e., the rear, thereby protecting the occupants' ankles, etc.

[0062] Furthermore, in this embodiment, grooves 3114 and 3124 are provided at the rear of the battery support surface of the battery support plate 31 supporting the battery B. As a result, the grooves 3114 and 3124 in the battery support plate 31 may collapse and deform into a steeper mountain shape, thus enabling the battery B to rotate easily.

[0063] Furthermore, in this embodiment, a curved portion 376 is provided on the upper battery support bracket 37 behind the slots 3114 and 3124, which is fixed to a rigid member 15 on the side of the vehicle body. The slots 3114, 3124, and curved portion 376 are disposed between the brake master cylinder device 12 and the mounting base 50 supporting the battery support plate 31. Thus, by utilizing the rigid mounting base 50 and the brake master cylinder device 12, which is an engine mounting component, the slots 3114, 3124, and curved portion 376 can be deformed, thereby allowing the battery B to be rotated easily.

[0064] Furthermore, in this embodiment, an opening 3101 is provided on the upper surface of the battery support plate 31, which serves as the battery support surface. As a result, the mounting base 50 below the battery support plate 31, which has the battery support surface, can be easily fastened to the engine or transmission, and workability is improved.

[0065] Furthermore, in this embodiment, the upper battery support bracket 37 has: an abutment surface 372 formed in a generally L-shaped cross-section and facing the brake master cylinder device 12; and a rear battery support surface 371. Thus, in the event of a frontal collision, the abutment surface 372 can reliably abut against the brake master cylinder device 12, and the rear battery support surface 371 can support the battery B.

[0066] Furthermore, in this embodiment, a plurality of cutouts 3115 and 3116 are provided in the groove 3114. As a result, the left support plate 311 and the right support plate 312 can be significantly deformed starting from the cutouts 3115 and 3116, thereby causing the groove 3114 to be significantly deformed.

[0067] Furthermore, in this embodiment, a rear support leg 36, which is connected to the front side frame 11, is attached to the upper battery support bracket 37. Thus, the upper battery support bracket 37 can support the battery B in the vehicle width direction, and the rear support leg 36 can support the battery B in the vertical direction, thereby providing stable support for the battery B.

[0068] Furthermore, in this embodiment, the groove 3114 is formed by an inclined portion 3117 and a vertical wall portion 3118, and the groove 3124 is formed by an inclined portion 3127 and a vertical wall portion 3128. Thus, the grooves 3114 and 3124 each have a generally L-shaped cross section, thereby allowing the battery support plate 31 to be easily deformed in the grooves 3114 and 3124.

[0069] Furthermore, in this embodiment, the vertical wall portions 3118 and 3128 are attached to the front surface of the rear support leg 36, namely the support plate fixing surface 362. Thus, the vertical wall portions 3118 and 3128 can support the left support plate portion 311, which has one battery support surface, and the right support plate portion 312, which has another battery support surface.

[0070] Furthermore, in this embodiment, a reinforcing bracket 35 for reinforcing the left support plate portion 311 is incorporated into the mounting base 50 that supports the battery support plate 31 having a battery support surface. As a result, the front portion of the left support plate portion 311 can be moved rearward by utilizing the reinforcing bracket 35 that follows the mounting base 50 during a frontal collision.

[0071] Next, the second embodiment of the present invention will be described. In the battery rotation structure 30A of the vehicle in the second embodiment, the following aspects differ from those of the battery rotation structure 30 of the vehicle in the first embodiment: a front support leg 60A is provided; and the battery support plate is composed of two independent plate members: a left support plate 311A ​​with the same structure as the left support plate portion 311 in the first embodiment, and a right support plate 312A with the same structure as the right support plate portion 312 in the first embodiment.

[0072] That is, the battery support surface that supports the battery is divided into the upper surface of the left support plate 311A ​​that constitutes one battery support surface, and the upper surface of the right support plate 312A that constitutes the other battery support surface. Apart from this, the configuration is the same as that of the battery pack 1 in the first embodiment. The same symbols are used to mark the same configurations, and their descriptions are omitted. Figure 9 This is an enlarged perspective view of the periphery of the front side frame 11 on which the vehicle's battery rotation structure 30A is installed, viewed from the rear and from above. Figure 10 This is an enlarged top view showing the periphery of the front side frame 11 where the vehicle's battery rotation structure 30A is installed.

[0073] The front support leg 60A has a connecting upper plate portion 61A, a support wall portion 62A, a fixed portion 63A, and an inclined plate portion 64A. The lower surface of the front end of the left support plate 311A ​​is joined and fixed to the upper surface of the connecting upper plate portion 61A. The upper surface of the front end of the right support plate 312A is joined and fixed to the lower surface of the connecting upper plate portion 61A. That is, the lower surface of the left support plate 311A ​​and the upper surface of the right support plate 312A, which constitute the battery support surface, are asymmetrically joined with respect to the connecting upper plate portion 61A of the front support leg 60A.

[0074] The support wall portion 62A and the inclined plate portion 64A extend downward from the connecting upper plate portion 61A and are integrally connected to the fixed portion 63A. More specifically, the support wall portion 62A extends approximately vertically downward from the left end of the connecting upper plate portion 61A, and the inclined plate portion 64A extends obliquely from the right end of the connecting upper plate portion 61A towards the front side frame 11. In this configuration, the connecting upper plate portion 61A of the front support leg 60A is inclined towards the upper surface of the right support plate 312A from the location where the left support plate 311A ​​is fixed. The fixed portion 63A is joined and fixed to the upper surface 111 of the front side frame 11.

[0075] Next, the operation of the vehicle's battery rotation structure during a frontal collision will be explained. Figure 11 This is an enlarged side view showing the state of the brake master cylinder device 12 before it collides with the vehicle's battery rotating structure 30A. Figure 12This is an enlarged side view showing the state of the brake master cylinder device 12 after it collides with the vehicle's battery rotating structure 30A.

[0076] like Figure 11 As shown, similarly to the first embodiment, at the moment before a frontal collision with the vehicle, the brake master cylinder device 12 is positioned further rearward than the contact surface 372 of the upper battery support bracket 37 of the vehicle's battery rotation structure 30A, and spaced apart from the contact surface 372.

[0077] Next, during a frontal collision, the front side frame 11 moves rearward. As a result, since a reinforcing bracket 35 supporting the front of the left support plate 311A ​​is fixed to the mounting base 50 fixed to the front side frame 11, the front support leg 60A supporting the front end of the left support plate 311A ​​is further fixed to the front side frame 11. Therefore, the battery B supported by the left support plate 311A, together with the front of the left support plate 311A, moves significantly rearward relative to the brake master cylinder assembly 12.

[0078] Then, the contact surface 372 collides with the brake master cylinder device 12, but when viewed from the side, the front ends of the mountain-shaped left support plate 311A ​​and right support plate 312A are pulled downward by the front support leg 60A, thus... Figure 12 As shown, with further deformation, the mountain shape becomes steeper. Consequently, in battery B, supported by the left support plate 311A ​​and the right support plate 312A, the front end rotates significantly downwards, while the rear end rises upwards, as... Figure 12 As shown, battery B rotates significantly forward and downward with the pressing plate 42 as the fulcrum.

[0079] According to this embodiment, the following effects are achieved.

[0080] In this embodiment, the battery support plate is configured to be divided into a left support plate 311A ​​and a right support plate 312A, and the upper surfaces constituting the battery support surface are also divided. This allows the left support plate 311A, which has one battery support surface, to be fixed to the mounting base 50, while the right support plate 312A, which has the other battery support surface, can be deformed into a mountain shape, and the battery support plate with the battery support surface can be made lighter.

[0081] Furthermore, in this embodiment, the left support plate 311A, which has one battery support surface, and the right support plate 312A, which has another battery support surface, are asymmetrically joined vertically relative to the front support leg 60A in front of them. As a result, the left support plate 311A ​​is pulled downward by the mounting base 50, and the right support plate 312A is deformed into a mountain shape and pulled upward, thus suppressing the separation of the battery B from the front support leg 60A.

[0082] Furthermore, in this embodiment, the front support leg 60A is inclined toward the right support plate 312A. As a result, the right support plate 312A can be easily deformed into a mountain shape by utilizing the torque effect.

[0083] This invention is not limited to the above-described embodiments; any modifications or improvements within the scope of achieving the objectives of this invention are included in this invention.

[0084] For example, in this embodiment, the engine mounting component is the brake master cylinder device 12, and the mounting base is the mounting member 50, but it is not limited to this.
