no. 1 Embodiment approach
[0033] In the adhesive fixing structure A of the battery according to the first embodiment of the present invention, as figure 1 and figure 2 As shown, it has: a plurality of battery cells 1, a bracket 2 with a plurality of bracket holes 21, an adhesive 3 for bonding the battery cells 1 and the bracket 2, a plurality of bus bars 4, and the bus bars 4 and the Insulator 5 between brackets 2.
[0034] The battery unit 1 is a cylindrical battery having an electrode surface 11 of a positive electrode and a negative electrode at an end portion in the axial direction, an electrode terminal serving as a positive electrode terminal at the electrode surface of the positive electrode, and an electrode terminal 11 serving as a negative electrode terminal at the electrode surface of the negative electrode. electrode terminals. A plurality of battery cells 1 are arranged axially aligned to form a battery pack 10 .
[0035] The bracket 2 is, for example, a plate-shaped body made of a me...
no. 2 Embodiment approach
[0057] The battery adhesive fixing structure B according to the second embodiment of the present invention differs from the first embodiment in that the bus bar module 6 has an auxiliary concave portion 9 . Other than that, it is substantially the same as the first embodiment. Next, differences from the first embodiment will be described.
[0058] like Figure 7 ~ Figure 9 As shown, in the adhesive fixing structure B of the battery according to the second embodiment, the bus bar module 6 has an auxiliary concave portion 9 .
[0059] like Figure 7 ~ Figure 9 As shown, the auxiliary concave portion 9 is provided on the side closer to the electrode terminal 12 than the concave portion 8 at the peripheral portion of the bus bar module hole 61 . The auxiliary concave portion 9 is in the shape of a groove having an opening on the holder-facing surface 52 of the insulator 5 . The opening of the auxiliary concave portion 9 faces the bracket hole 21 . In addition, the opening sha...
no. 3 Embodiment approach
[0068] The battery adhesive fixing structure C according to the third embodiment of the present invention differs from the first embodiment in that the insulator constituting the bus bar module 6 protrudes toward the bus bar module hole 61 . Other than that, it is substantially the same as the first embodiment. Below, refer to Figure 10 ~ Figure 12 , the difference from the first embodiment will be described.
[0069] like Figure 10 ~ Figure 12 As shown, in the adhesive fixing structure C of the battery according to the third embodiment, the size of the hole diameter of the bus bar hole 41 arranged at the bus bar 4 and the insulator hole 51 arranged at the insulator 5 are different. Specifically, the diameter of the insulator hole 51 is smaller than that of the bus bar hole 41 . Thereby, the form in which the insulator 5 protrudes into the bus bar module hole 61 is adopted.
[0070] In this embodiment, the insulator 5 protruding toward the bus bar module hole 61 is provi...
