[ Effect of the invention ]
According to the invention described in claim 1, when the vehicle undergoes a front side collision and the front side frame deforms, the power unit attachment located above the vehicle pushes up the battery. At this time, the leg portion supporting the battery base is extended upward in accordance with the deformation of the opening by crushing. Accordingly, by providing the leg portion supporting the battery base with an extension amount, the locking member and the upper end locking portion can be prevented from being deformed or torn, the locked state between the locking member and the upper end locking portion can be maintained, and the battery can be reliably held in the battery base.
According to the invention described in claim 2, when the battery is pushed up by a front side collision of the vehicle, the locking member and the upper end locking portion are lifted upward together with the battery, and the periphery of the upper end locking portion of the battery base is bent and deformed about the lower end corner portion of the battery as a fulcrum. At this time, since an appropriate space is secured between the locking bolt and the side surface of the battery, the upper end locking portion moves upward without hindering the bending deformation of the battery base. Accordingly, the battery base is bent and deformed to absorb energy, and the upper end locking portion is prevented from being broken, so that the battery can be reliably held by the battery base.
According to the invention described in claim 3, when the battery is pushed up by a vehicle front side collision, the rear leg portion rotates from the inclined state in the forward direction to the vertical state, and the front-lower end bent portion of the front leg portion having the notch is pulled out from between the front bolt and the front side frame and rotates from the vertical state to the inclined state in the rearward direction. Accordingly, the entire battery base moves upward, and therefore, the breakage of the upper end locking portion can be suppressed, and the battery can be reliably held by the battery base. Further, since the front leg portion is erected substantially vertically on the front side frame, the vehicle-mounted member can be easily disposed in front of the front leg portion.
According to the invention described in claim 4, since the front leg portion and the rear leg portion are formed in an L-shaped cross section and the upper end portions of the front leg portion and the rear leg portion are connected to each other by the connecting wall substantially parallel to each inner wall, the leg portion can be easily expanded and deformed upward and easily rotated between the inclined state and the vertical state while maintaining the strength thereof while being compact (compact). Accordingly, the entire battery base can be easily moved upward, and the breakage of the upper end locking portion can be suppressed, so that the battery can be reliably held by the battery base. Further, the leg portion can be easily attached to the front side frame by the positioning portion, and the support strength of the leg portion can be appropriately secured by the reinforcing flange.
According to the invention described in claim 5, the battery base is joined to the joining flanges at the upper ends of the front leg portion and the rear leg portion, and the bent flange at the upper end of the connecting wall is joined to the bottom wall of the battery base, whereby the strength and rigidity of the upper end locking portions of the front leg portion and the rear leg portion can be improved, and the support strength for the battery can be ensured.
According to the invention described in claim 6, even if the hook portion of the locking bolt moves upward together with the battery, the partition portion deforms to the inside of the second locking hole to absorb the movement energy of the hook portion, and even if the partition portion is torn, the hook portion can be locked in the second locking hole to maintain the locked state between the locking member and the upper end locking portion. Accordingly, the battery can be reliably held by the battery base.
According to the invention described in claim 7, the battery can be stably supported while suppressing the battery from falling into the engine compartment. In addition, since the battery base is fixed to the wall plate portion of the engine compartment side wall having relatively low strength, the influence on the deformation of the leg portion can be suppressed.

Referring to fig. 2, the battery 11 is arranged such that the front side surface 11b thereof substantially overlaps the front edge 14a of the bottom wall 14 of the battery base 13 in a plan view, while the rear side surface 11c thereof is arranged to be offset forward by a distance a from the rear edge 14b of the bottom wall 14 of the battery base 13. The battery 11 is disposed such that its left and right side surfaces substantially overlap with the left and right ends of the battery base 13 in a plan view, and its rear outer corner portion protrudes above the rear outer recess 17 of the battery base 13.
The locking bolts 22 and 23 are disposed substantially parallel to the side surfaces of the battery 11. The hook portions 22b, 23b of the locking bolts 22, 23 are inserted into the front and rear upper end locking portions 38, 39 of the battery base 13 from the battery 11 side and locked (see fig. 4, 5).
referring to fig. 3, in the fixed state of the battery 11, a first distance a1 from the rear upper end locking portion 39 of the battery base 13 to the rear side surface 11c of the battery 11 is secured to be equal to a second distance a2 from the axial center of the rear locking bolt 23 on the rear locking bolt mounting portion 21c of the pressing bracket 21 to the rear side surface 11c of the battery 11, or the first distance a1 is secured to be greater than the second distance a 2.
Next, the operation of the present embodiment will be described.
When the front side frame 5 is bent and deformed to absorb collision energy in a front side collision of the vehicle, the power unit attachment 9 fixed to the upper surface 5b of the front side frame 5 is raised and the battery 11 above the power unit attachment 9 is pushed up. At this time, the pressing bracket 21 and the locking bolts 22 and 23 of the clamp member 20 are also raised, and the upper end locking portions 38 and 39 of the leg portion 30 locked by the hook portions 22b and 23b of the locking bolts 22 and 23 are pulled up.
At this time, the leg portion 30 restricts the rise of the upper end locking portions 38 and 39, and the locking bolts 22 and 23 bend or the like to cause the hook portions 22b and 23b to fall off the upper end locking portions 38 and 39, or the upper portions of the locking holes 38a and 39a of the upper end locking portions 38 and 39 break to cause the hook portions 22b and 23b to fall off.
In contrast, in the present embodiment, the leg portion 30 of the battery base 13 is formed of a metal plate intersecting the vehicle longitudinal direction, and has an opening 31d, 32d at the center in the width direction, the width increases as it goes upward, the lower end bent portions 34, 35 are provided at the lower end of the leg portion 30, the lower end bent portions 34, 35 are fixed to the upper surface 5b of the front side frame 5, the upper end locking portions 38, 39 are provided at the upper end of the leg portion 30, and the upper end locking portions 38, 39 are positioned above the openings 31d, 32d and lock the bolts 22, 23.
therefore, when the front side frame 5 is deformed at the time of a front side collision of the vehicle, the power unit attachment 9 is lifted, and the battery 11 is pushed up, the leg portions 30 of the battery base 13 have an expansion amount extending upward as the openings 31d, 32d are crushed. Accordingly, the locking bolts 22 and 23 and the upper end locking portions 38 and 39 are prevented from being deformed or torn, and the locked state between the locking bolts 22 and 23 and the upper end locking portions 38 and 39 is maintained, whereby the battery 11 can be reliably held in the battery base 13.
In the present embodiment, the first distance a1 from the rear upper end locking portion 39 to the rear side surface 11c of the battery 11 is equal to the second distance a2 from the axial center of the rear locking bolt 23 on the rear locking bolt mounting portion 21c to the rear side surface 11c of the battery 11, or the first distance a1 is longer than the second distance a 2.
Therefore, even if the rear locking bolt 23 and the rear upper end locking portion 39 are lifted upward together with the battery 11 when the vehicle is involved in a front-side collision and the battery 11 is pushed up, the periphery of the rear upper end locking portion 39 of the battery base 13 is bent and deformed about the lower end corner of the battery 11 as a fulcrum, and an appropriate space (clearance) can be secured between the rear locking bolt 23 and the side surface of the battery 11. Accordingly, since the rear upper-end locking portion 39 moves upward without inhibiting the bending deformation of the battery base 13, the energy is absorbed by the bending deformation of the battery base 13, and the breakage of the rear upper-end locking portion 39 can be further suppressed.
In the present embodiment, the front leg portion 31 of the leg portion 30 is erected substantially vertically on the upper surface 5b of the front side frame 5 in a side view, the rear leg portion 32 of the leg portion 30 is erected on the upper surface 5b of the front side frame 5 so as to be inclined forward toward the upper side than the front leg portion 31 in a side view, the front lower end bent portion 34 of the front leg portion 31 is fastened to the front side frame 5 by inserting the front bolt 36 through the cutout hole 34b opened at the front flange end thereof, and the rear lower end bent portion 35 of the rear leg portion 32 is fastened to the front side frame 5 by inserting the rear bolt 37 through the through-hole 35b closed in the periphery.
therefore, when the battery 11 is pushed up by a vehicle front side collision, the rear leg portion 32 is rotated from the inclined state in the forward direction to the vertical state, and the front lower end bent portion 34 of the front leg portion 31 having the cutout hole 34b is pulled out from between the front bolt 36 and the front side frame 5 and is rotated from the vertical state to the inclined state in the rearward direction. Accordingly, since the entire battery base 13 moves upward, the upper end locking portions 38 and 39 can be prevented from being broken.
In the present embodiment, the front leg portion 31 and the rear leg portion 32 have inner side walls 31a, 32a substantially parallel to the inner side surface 5a of the front side frame 5 and rising walls 31b, 32b substantially perpendicular to the inner side walls 31a, 32a, respectively, and are formed in an L-shaped cross section, and the upper end portions of the inner side walls 31a, 32a of the front leg portion 31 and the rear leg portion 32 are connected by a connecting wall 33 substantially parallel to the inner side walls 31a, 32 a.
Therefore, the leg portion 30 can be made compact (compact) and its strength can be secured, and the leg portion 30 can be easily extended and deformed upward and can be easily rotated between the inclined state and the vertical state. This facilitates the upward movement of the entire battery base 13, and prevents the upper end locking portions 38 and 39 from being broken.
In the embodiment, the rear upper end locking portion 39 of the rear leg portion 32 includes: a first locking hole 39a for locking the hook 23b of the bolt 23; and a second locking hole 39b located above the first locking hole 39a with a partition 39c therebetween.
Therefore, even if the hook portion 23b of the rear locking bolt 23 moves upward together with the battery 11, the partition portion 39c deforms inward of the second locking hole 39b, and the rising energy of the hook portion 23b is absorbed. Even if the partition portion 39c is torn, the hook portion 23b is locked to the second locking hole 39b, and the locked state between the rear locking bolt 23 and the rear upper end locking portion 39 can be maintained.
As described above, according to the automotive battery mounting structure of the present embodiment, when the vehicle is subjected to a front-side collision and the battery 11 on the front side frame 5 is pushed up, the leg portions 30 of the battery base 13 are crushed by the openings 31d, 32d and have an amount of upward expansion, whereby the locking bolts 22, 23 and the upper end locking portions 38, 39 are prevented from being deformed or torn, the locking state between the locking bolts 22, 23 and the upper end locking portions 38, 39 is maintained, and the battery 11 can be reliably held on the battery base 13.
further, since the first distance a1 from the rear upper end locking portion 39 to the rear side surface 11c of the battery 11 is equal to the second distance a2 from the axial center of the rear locking bolt 23 on the rear locking bolt mounting portion 21c to the rear side surface 11c of the battery 11, or the first distance a1 is longer than the second distance a2, the rear upper end locking portion 39 moves upward without hindering the bending deformation of the battery base 13, and the energy is absorbed and the breakage of the rear upper end locking portion 39 is suppressed, and the battery 11 can be reliably held in the battery base 13.
Further, the rear locking bolt 23 and the rear upper end locking portion 39 are disposed apart from the rear side surface 11c of the battery 11, whereas the front locking bolt 22 and the front upper end locking portion 38 are disposed relatively closer to the front side surface 11b of the battery 11, and the rear leg portion 32 is disposed obliquely forward, whereas the front leg portion 31 is disposed substantially perpendicular to the upper surface 5b of the front side frame 5, whereby the disposition space S1 of the vehicle-mounted components in front of the front leg portion 31 can be secured large.
Further, since the front leg portion 31 is erected substantially perpendicularly to the front side frame 5, the rear leg portion 32 is erected obliquely forward on the front side frame 5, and the front lower end bent portion 34 of the front leg portion 31 is fastened to the front side frame 5 by inserting the front bolt 36 through the cutout hole 34b opened forward, the entire battery base 13 is easily moved upward when the battery 11 is pushed up by a front side collision of the vehicle, whereby breakage of the upper end locking portions 38 and 39 is suppressed, and the battery 11 can be reliably held on the battery base 13.
