Detailed Description

In order to make those skilled in the art better understand the technical solutions of the present application, the following detailed description is made with reference to the accompanying drawings and the detailed description.

As shown, the battery module includes an output electrode 400, a holder, an end plate 300, and the like.

The output electrode 400 (typically, a copper bar or an aluminum bar) extends from one end of the battery module to above the end plate 300. The bottom of the support is connected with the end plate in a positioning mode, the output pole is supported at the top of the support, and the bolt penetrates through the through hole of the output pole and then is screwed in the threaded hole of the support, so that the output pole is supported and positioned.

In the past, after the assembly of the battery module is completed, the support cannot be disassembled, and once the threaded hole of the support is screwed or damaged, the whole battery module can only be scrapped, so that the maintenance cost of the battery module is overhigh.

The support comprises a support body 100 and a nut 200, wherein the threaded hole is formed in the nut 200, and the axis direction of the threaded hole is Z direction. The support body 100 is connected with the end plate 300 in a positioning manner, the support body 100 is provided with a nut mounting hole a, and the nut 200 is mounted in the nut mounting hole a. The side portion of the holder body 100 is provided with a side notch b, the side notch b is communicated with the peripheral wall of the nut mounting hole a, and the nut 200 can be translated through the side notch b along the X direction perpendicular to the Z direction.

By the design, once the threaded hole is threaded or damaged, the bolt can be unscrewed, the damaged nut 200 is moved out of the nut mounting hole a from the side notch b, the new nut 200 is moved into the nut mounting hole a from the side notch b, and then the bolt is screwed, so that the battery module can be put into use again only by replacing the nut 200, the battery module does not need to be scrapped, and the maintenance cost of the battery module is reduced.

Specifically, one of the side portion of the nut 200 and the side portion of the seat body 100 may have a locking recess e, and the other may have a locking protrusion c inserted into the locking recess e, and the bottom surface of the locking protrusion c and the bottom wall of the locking recess e are abutted against each other, thereby limiting the nut 200 to move upward along the Z direction. The arrangement of the detent projections c and the detent recesses e makes the relative positions of the nut 200 and the holder body 100 more stable, and thus the output electrode 400 is more reliably positioned.

The insertion direction of the protruding detent portions c and the recessed detent portions e may be along the X direction, and the protruding detent portions c or the recessed detent portions e provided on the holder body 100 and the side notches b are provided on the same side of the holder body 100. Thus, when the nut 200 translates outwards along the X direction, the clamping convex part c can automatically fall out of the clamping concave part e, and when the nut 200 translates inwards along the X direction, the clamping convex part c can automatically insert into the clamping concave part e, so that the assembly and disassembly operations are simpler and more convenient.

The detent recess e can be provided in the nut 200 and designed as a snap ring. This allows the hand-held snap ring to pull or push nut 200 in translation in the X-direction, thereby further facilitating assembly and disassembly of nut 200. In the illustrated embodiment, the bottom wall of the snap ring is partially raised upward, and the raised position abuts against the locking protrusion c provided on the holder body 100, so that the raised position is relatively easily elastically deformed, and thus the possibility of a large gap between the nut 200 and the holder body 100 due to vibration is reduced to some extent.

Specifically, the nut 200 includes a post 201, and the threaded hole is provided in the post 201. The number of the pillar portions 201 may be one or more, and each pillar portion 201 is provided with a threaded hole. When the plurality of column parts 201 are provided, the column parts 201 are sequentially arranged at intervals along the Y direction perpendicular to both the X direction and the Z direction, so that the translation of the nut 200 along the X direction is not affected. When a plurality of column parts 201 are arranged, a plurality of thread mounting holes a are correspondingly arranged on the support body 100, and each column part 201 is respectively mounted on one nut mounting hole a, so that the whole nut 200 cannot rotate around the Z direction relative to the support body 100, and connection looseness of the bolt caused by the fact that the nut 200 rotates around the Z direction is avoided.

Specifically, the nut 200 further includes a limiting plate 202, the limiting plate 202 is disposed on the periphery of the top end of the column portion 201, and the bottom surface of the limiting plate 202 abuts against the support body 100, so that the nut 200 is limited to move downward along the Z direction, and thus, the relative position between the nut 200 and the support body 100 is more stable, and the output electrode is more reliably positioned. The catching recess e may be provided at one side edge of the stopper plate 202.

Specifically, the nut 200 may be an integral stamping, such that the overall strength of the nut 200 is relatively high and the molding cost is low.

Specifically, the holder body 100 includes a holder body 101 and a connection arm body 102. The carrier body 100 may be a one-piece injection molded part, such that the carrier body 100 has high overall strength and low molding cost.

The bottom surface of the seat body 101 is supported on the top surface of the end plate 300 of the battery module, and the top surface of the seat body 101 is in close contact with the bottom surface of the limit plate 202 of the nut 200. The nut mounting hole a and the side notch b are provided in the base body 101. In the illustrated embodiment, two opposite sides of the top surface of the seat body 101 in the Y direction are provided with protruding lugs d protruding upward, and the limit plate 202 and the output pole 400 of the nut 200 are limited between the protruding lugs d on the two sides, so that the limit plate 202 and the output pole 400 of the nut 200 cannot move in the Y direction relative to the seat body 101.

The connecting arm 102 is disposed at the bottom of the base 101, and the connecting arm 102 is inserted into a slot of the end plate 300 of the battery module. Furthermore, a clamping hole may be formed in a side wall of an end plate slot of the battery module, and a protrusion (not shown) may be disposed on a side portion of the connecting arm 102, so that after the connecting arm 102 is inserted into the end plate slot, the protrusion on the side portion of the connecting arm 102 is just clamped into the clamping hole in the side wall of the end plate slot, thereby making the positioning connection between the holder body 100 and the end plate 300 more reliable.

It should be noted that in the description of the present application, the directions or positional relationships indicated by "upper", "lower", and the like are based on the directions or positional relationships shown in the drawings, and are only for the purpose of simplifying the description, and do not indicate or imply that the system or element referred to must have a specific direction, be constructed and operated in a specific direction, and thus, cannot be understood as a limitation of the application.
