Battery block and secondary battery module
First Claim
1. A battery block, comprising:
- a cylindrical plurality of battery cells arranged; and
two holding members sandwiching the arrangement of the battery cells from a radial direction of the battery cells for holding, the two holding members facing each other, whereinfirst holding recesses are formed by first semicircular members on one of the two holding members, each first semicircular member holding an outer periphery of each end of each battery cell in a respective first holding recess,two protrusions extending radially inwardly from the first semicircular member and in contact with an outer peripheral face of each end of each battery cell are formed at each first holding recess,second holding recesses are formed by second semicircular members on the other holding member, each second semicircular member holding an outer periphery of each end of each battery cell in a respective second holding recess and being arranged opposite to the corresponding first holding recess,an elastically deformable pressing part that presses the outer peripheral face of the battery cell inwardly in the radial direction is integrally formed along each second holding recess, andthe two protrusions are in contact with an outer peripheral face of each end of each battery cell and the elastically deformable pressing part presses the outer peripheral face, thereby allowing the two holding members to hold the plurality of battery cells,wherein the elastically deformable part includes a pair of connecting legs connected to a base portion of the other holding member and an elastically deformable leg connected at its ends to the pair of connecting legs and being spaced from the base portion of the other holding member.

Abstract
Provided are a battery block and a secondary battery module capable of holding a plurality of battery cells stably and so reducing a load applied to a welding part of a conductive member that is connected to an electrode by welding or the like. The battery block includes a lower holding frame and a middle holding frame, one of which includes two protrusions that are in contact with an outer peripheral face of each battery cell and the other includes a pressing part that presses the outer peripheral face of the battery cell inwardly in the radial direction. Then, one of an upper holding frame and the middle holding frame includes two protrusions that are in contact with an outer peripheral face of each battery cell and the other includes a pressing part that presses the outer peripheral face of the battery cell inwardly in the radial direction.
