Abstract

A holding member holding an energy storage device is provided with: a first frame including an end member aligned with the energy storage device, and an attachment portion connected to the end member; a second frame including a body aligned with the energy storage device, and an extension extending from the body and extending along the outer surface of the end member; and a plurality of coupling portions that couple the first frame and the second frame in a first direction and disposed in the extension at an interval in a second direction. The attachment portion includes an installation portion that is installed on a fixing surface. The other coupling portion is further apart from a center line extending in the second direction of the end member than a coupling portion closest to the installation portion.

First claim

The invention claimed is:

1. An energy storage apparatus comprising:
at least one energy storage device; and
a holding member that holds the at least one energy storage device,
wherein
the holding member includes
a first frame including an end member aligned with the at least one energy storage device in a first direction and an attachment portion connected to one end of the end member in a second direction orthogonal to the first direction,
a second frame including a body aligned with the at least one energy storage device in a third direction orthogonal to the first direction and the second direction, and an extension extending from the body and extending along at least an outer surface of the end member, and
a plurality of coupling portions that couple the first frame and the second frame in the first direction and are disposed in the extension at an interval in the second direction,

the attachment portion includes an installation portion that is installed on a fixing surface to which the first frame is fixed,
the plurality of coupling portions include a coupling portion closest to the installation portion and an other coupling portion in a view of the first direction of the first frame, and
in the third direction, the other coupling portion is further apart from a center line extending in the second direction of the end member than the coupling portion closest to the installation portion.

2. The energy storage apparatus according to claim 1 , wherein the other coupling portion is disposed on an imaginary straight line passing through the coupling portion closest to the installation portion and a fixing center of the installation portion in the view of the first direction of the first frame.

3. The energy storage apparatus according to claim 1 , wherein
the first frame includes a pair of first frames disposed on both sides of the at least one energy storage device in the first direction,
the second frame includes a pair of second frames disposed on both sides of the at least one energy storage device in the third direction, and
the plurality of coupling portions coupling one of the second frames and the first frame and the plurality of coupling portions coupling an other of the second frames and the first frame are symmetrically disposed with respect to a center line extending in the second direction of the end member of the first frame.

4. The energy storage apparatus according to claim 3 , wherein
the attachment portion includes a pair of legs disposed at an interval in the third direction and each extending in the second direction from the one end of the end member, and
each of the pair of legs has
a first end connected to the one end of the end member and including an extending portion that extends in the second direction from the one end of the end member, and
a second end opposite to the first end and including the installation portion.

5. The energy storage apparatus according to claim 4 , wherein at a side end portion that is an end portion in the end member and the extending portion in the third direction, a first site including an end portion on the installation portion side in the second direction and a second site adjacent to the first site in the second direction bend toward sides opposite to each other with respect to a site adjacent to the side end portion in the third direction in the end member and the extending portion, and a boundary portion between the first site and the second site is twisted.

6. The energy storage apparatus according to claim 5 , wherein
the leg includes the installation portion extending from a tip of the extending portion along the first direction, the installation portion being in a plate shape along a plane including the first direction and the third direction, and
an installation-portion side end portion being the end portion in the third direction in the installation portion is continuous with the first site and bent toward a side where the first site is located with respect to a site adjacent to the installation-portion side end portion in the installation portion in the third direction.

7. An energy storage apparatus comprising:
at least one energy storage device; and
a holding member that holds the at least one energy storage device,
wherein
the holding member includes
a first frame including an end member aligned with the at least one energy storage device in a first direction and an attachment portion connected to one end of the end member in a second direction orthogonal to the first direction,
a second frame including a body aligned with the at least one energy storage device in a third direction orthogonal to the first direction and the second direction, and an extension extending from the body and extending along at least an outer surface of the end member, and
a plurality of coupling portions that couple the first frame and the second frame in the first direction and are disposed in the extension at an interval in the second direction,

the attachment portion includes an installation portion that is installed on a fixing surface to which the first frame is fixed,
the plurality of coupling portions include a coupling portion farthest from the installation portion and an other coupling portion in a view of the first direction of the first frame,
the coupling portion farthest from the installation portion is further apart from a center line extending in the second direction of the end member in the third direction than the other coupling portion, and
the other coupling portion is disposed on an imaginary straight line passing through the coupling portion farthest from the installation portion and a fixing center of the installation portion in the view of the first direction of the first frame.
