Abstract

Two side members are provided so as to be in side portions of a vehicle. Each side member is provided with a kick-up portion curved upward. A cross member is provided so as to interconnect side surfaces of forward portions of the kick-up portions of the two side members. A forward portion of a battery pack is fixed to an upper surface of the cross member via forward brackets welded to the forward portion of the battery pack. A rearward portion of the battery pack is fixed to upper surfaces of rearward portions of the kick-up portions of the two side members via a bridge provided so as to interconnect the two side members.

Claims

1. A mounting structure for a storage battery device installed in a vehicle, comprising:

a frame that extends in a longitudinal direction of the vehicle,

wherein the frame has a deformable portion that deforms in an up-down direction by a load in the longitudinal direction of the vehicle; and

a fixing member that fixes the storage battery device to the frame so that the storage battery device moves relatively to the deformable portion when the deformable portion deforms,

wherein the deformable portion is a kick-up portion formed by bending the frame upward,

wherein the fixing member is a member that fixes the storage battery device to an upper surface of the kick-up portion of the frame, and

wherein the fixing member is adapted to deform to increase a space in an up-down direction between a rearward portion of the storage battery device and a rearward portion of the kick-up portion.

3. The mounting structure according to claim 1, wherein the fixing member fixes the storage battery device to the upper surface of the kick-up portion of the frame at a portion forward of a rearward end of the storage battery device.

4. The mounting structure according to claim 1, wherein the mounting structure further comprises means for fixing a forward portion of the storage battery device to a forward portion of the kick-up portion, and

wherein the fixing member is a member that fixes a rearward portion of the storage battery device to a rearward portion of the kick-up portion.

5. The mounting structure according to claim 1, wherein two of said frame are provided so as to be in side portions of the vehicle,

wherein the fixing member comprises a bridge portion that connects the two frames in a transverse direction of the vehicle, and

wherein the storage battery device is fixed to the frames via the bridge portion.

6. The mounting structure according to claim 5, wherein the fixing member fixes the storage battery device to the frames, in a rearward portion of the vehicle, and

wherein the bridge portion is provided rearward of the storage battery device.

7. The mounting structure according to claim 6, wherein the bridge portion is disposed at a position that is above a vertical position of a bottom surface of the storage battery device and is below a vertical position of an upper surface of the storage battery device.

8. The mounting structure according to claim 1, wherein the storage battery device is disposed within a trunk compartment of the vehicle.
