POWER STORAGE DEVICE

摘要

A power storage device including a battery containing body and a chassis for housing the body, further including
a first guide rail for receiving a first end portion on a lower side of the body and a second guide rail for receiving a second end portion on an upper side of the body, when inserting and removing the flat battery containing body upright,wherein the first guide rail includes a pair of a higher side plate and a lower side plate which are different in height from each other and extend in an insertion direction, and a receiving portion including a stopper at an end portion of the rail;at a vicinity of a corner portion on a back side in the insertion direction of the first end portion of the battery containing body, a first protrusion portion is provided such that, when removing the battery containing body, the first protrusion portion engages with the stopper, thereby preventing the battery containing body from dropping; andat a vicinity of a corner portion on the back side in the insertion direction of the second end portion of the battery containing body, a second protrusion portion is provided such that,when the battery containing body is turned upside down, an attempt to insert the battery containing body with the first end portion received by the second guide rail and the second end portion received by the first guide rail is made, the second protrusion portion engages with the higher side plate, thereby blocking the insertion, andwhen an attempt to remove the battery containing body from the receiving portion is made, the second protrusion portion engages with the stopper, thereby preventing it from dropping.

主权项

1. A power storage device comprising a battery containing body and a chassis for housing the battery containing body,
wherein at a side surface portion of the chassis, an opening for inserting and removing the battery containing body via the side surface portion is provided; the battery containing body has a flat shape and is housed and placed upright such that an end portion of the battery containing body faces the opening; the chassis includes, inside, a first guide rail for receiving a first end portion on a lower side of the battery containing body when inserting and removing the battery containing body and a second guide rail for receiving a second end portion on an upper side of the battery containing body when inserting and removing the battery containing body; the first guide rail comprises a pair of side plates facing each other and extending in an insertion direction, the pair of side plates supporting the first end portion on the lower side of the battery containing body, one of the side plates being a higher side plate that is higher than the other side plate and the other side plate being a lower side plate that is lower than the higher side plate; at an end portion on the opening side of the first guide rail, a receiving portion including a stopper is provided; at a vicinity of a corner portion on a back side in the insertion direction of the first end portion on the lower side of the battery containing body, a first protrusion portion is provided such that, when removing the battery containing body, the first protrusion portion engages with the stopper, thereby preventing the battery containing body from dropping; and at a vicinity of a corner portion on the back side in the insertion direction of the second end portion on the upper side of the battery containing body, a second protrusion portion is provided such that, when the battery containing body is turned upside down, the vicinity of the back-side corner portion of the second end portion is placed on the receiving portion, and then an attempt to insert the battery containing body with the first end portion of the battery containing body received by the second guide rail and the second end portion of the battery containing body received by the first guide rail is made, the second protrusion portion engages with the higher side plate of the first guide rail, thereby blocking the insertion of the battery containing body, and when an attempt to remove the battery containing body in a direction opposite to the insertion direction from the receiving portion is made, the second protrusion portion engages with the stopper, thereby preventing the battery containing body from dropping.
