Type.
Refering to fig. 1 to Fig. 3, the end plate of the utility model embodiment includes: end plate body 1 and bolster 2；Wherein, end plate
Ontology 1 may be mounted at the both ends of battery modules 3；The bolster 2 is with the end plate body 1 close to the side phase of battery modules
Connection, in cell expansion, to generate deformation to absorb the pressure energy of battery bulging generation.
Specifically, end plate body 1 can be metalwork or plastic part with rigidity, as end plate body 1 can be
The metal plate that metallic aluminium is formed by way of extrusion molding.The size of end plate body 1 can be determined according to the actual situation.
As end plate body 1 can be more than or equal to the size of battery modules along the size of short transverse (up and down direction in Fig. 3)；End plate sheet
Body 1 in the width direction (direction of vertical paper in Fig. 3) size can be more than or equal to battery modules size.Specific installation
When, each battery mould in each mounting hole a opened up on end plate body 1 and battery modules 3 can be successively fed through by connecting rod 4
Mounting hole on block realizes the assembly of end plate and battery modules 3.
Bolster 2 can be made of the material with certain elasticity capacity, in an embodiment of the present embodiment,
Bolster 2 is flexible flexible material, also, bolster 2 and 1 bonding connection of end plate body.For example, buffering
Part 2 can be made using rubber or foam material, when installation, can be bonded in end plate body 1 using structure glue
Inner surface (towards the side of battery modules 3) opens up a mounting groove in 1 inner surface of end plate body, and bolster 2 is bonded
In mounting groove.
Those skilled in the art can determine the size of bolster 2 according to the size of end plate body 1；Wherein, bolster 2
Planar structure has can be set in the surface being in contact with end plate body 1, to increase contact area, be connected to the two can preferably
Together；The surface that bolster 2 is contacted with battery modules 3, can be set curved-surface structure, so that end plate body 1 and battery mould
