The utility model in order to better understand, below with reference to Fig. 1 to Fig. 9 according to the shell component of the utility model embodiment
It is described in detail with battery modules.
Fig. 1 is a kind of structural schematic diagram of battery modules provided by the embodiment of the utility model, and Fig. 2 is the utility model
A kind of configuration schematic diagram for battery modules that embodiment provides.Battery modules include: shell component, have accommodating chamber 120；It is more
A single battery 300, is arranged side by side along third direction in accommodating chamber 120.Wherein, third direction is the Y-direction in Fig. 1.
Shell component generally includes shell 100, the side plate being set to inside shell 100 200 and is set to 100 both ends of shell
End plate 400, shell 100 are usually docked and are welded by one piece of plate bending and formed.Therefore shell 100 generally includes to connect in succession
Multiple wall portions 110, the accommodating chamber 120 being enclosed by multiple wall portions 110 and the opposite port 130 being connected to accommodating chamber 120,
There is the butt weld 140 extended between two ports 130, end plate at least one wall portion 110 in multiple wall portions 110
400 are set at port 130, and side plate 400 is set to accommodating chamber 120, and side plate 400 be located at single battery 300 and wall portion 110 it
Between.
It is not limited here, side plate 200 is one to the number of side plate 200, and a side plate 200 is set to accommodating chamber 120, and
It is arranged corresponding to 140 place wall portion 110 of butt weld；Or side plate 200 is two, is relatively arranged on accommodating chamber 120, at least
One side plate 200 is arranged corresponding to 140 place wall portion 110 of butt weld.
There are many set-up modes of side plate 200, and in some alternative embodiments, side plate 200 includes in a first direction
Opposite first surface 211 and second surface 212, first surface 211 are recessed to form fluted 213 along first direction.Work as side plate
200 when being set in the accommodating chamber 120 of shell 100, and side plate 200 and 140 place wall portion 110 of butt weld are correspondingly arranged, and
Side plate 200 extends between two ports 130, and the opening of groove 213 is arranged towards weld seam 140, and single battery 300 is located at
Side of the second surface 212 far from first surface 211.Wherein, first direction refers to the X-direction in Fig. 3.
When the welding of multiple wall portions 110 is formed shell 100 using butt weld 140 by the outside by shell 100, due to side
Plate 200 is relatively close apart from wall portion 110 where weld seam, and welding light transmission may damage side plate 200, and then penetrate side plate 200
Single battery 300 is damaged.But in the present embodiment, it is arranged fluted 213 on first surface 211, and groove 213
Opening is towards weld seam 140, therefore groove 213 can increase the distance between butt weld 140 and first surface 211, when
By the outside of shell 100 when the welding of multiple wall portions 110 is formed shell 100 by butt weld 140, due to butt weld 140
Farther out, can be avoided welding light transmission can drop the distance between first surface 211 to damage caused by side plate 200, while also
Low welding light transmission damages 300 bring of single battery.
It is understood that the depth that the depth of groove 213, i.e. groove 213 extend in a first direction is it is not limited here,
User can set according to actual needs.However, to ensure that the intensity of side plate 200, avoids groove 213 too deep so that side
The intensity of plate 200 is insufficient, and the depth of side plate 200 should be less than or equal to 2/3rds of 200 thickness of side plate.Simultaneously in order to abundant
Guarantee that the distance between 200 first surface 211 of side plate and butt weld 140 are remote enough, the depth of groove 213 should be greater than or wait
In the one third of 200 thickness of side plate.
In some alternative embodiments, opening has interposition in 200 second direction of side plate, and interposition corresponds to
Butt weld 140 is arranged.Wherein, the interposition being open here refers to close to the upper intermediate position in a second direction that is open, but simultaneously
The intermediate position of stricti jurise opening is not referred to, as long as within the scope of certain error, the interposition of opening is corresponded roughly to pair
Welding seam 140 is arranged.Wherein, second direction refers to the Z-direction in Fig. 3.
In these optional embodiments, the interposition of opening corresponds to butt weld 140, fully ensures that Fig. 3 further groove
The first surface 211 of about 213 two sides farther out, further avoids welding light transmission and brings to side plate 200 apart from butt weld 140
Damage.
In some alternative embodiments, side plate 200 includes: plate-like portion 210, is extended in a second direction, and first surface
211 and second surface 212 be all set in plate-like portion 210, plate-like portion 210 includes two sides being oppositely arranged along Z-direction；Limit
Portion 220 is connected at least one of two sides, and protrudes from the setting of second surface 212.
It, can be to single battery 300 by the way that limiting section 220 is arranged on plate-like portion 210 in these optional embodiments
It is limited, guarantees the stability of relative position between single battery 300 and side plate 200, while being also convenient for the dress of battery modules
Match, improves the assembly efficiency of battery modules.
It is understood that herein without limitation to the number of limiting section 220, limiting section 220 can be one, it is set to
Plate-like portion 210 limits single battery 300 by a limiting section 220 along the either above or below of Z-direction.
Preferably, limiting section 220 is two, and two limiting sections 220 are connected to two sides.Pass through two limits of setting
Single battery 300 can be set between two limiting sections 220 by position portion 220, be provided in both direction to single battery 300
Limit so that the relative position between single battery 300 and side plate 200 is more stable.
The shape of groove 213 it is not limited here, in some alternative embodiments, as shown in Figure 6 and Figure 7, groove 213
U-shaped profile, the bottom wall including two inner wall 213a of two inner wall 213a being spaced apart in second direction and connection
213b.Wherein, the connection type between inner wall 213a and bottom wall 213b it is not limited here, such as inner wall 213a and bottom wall 213b
Between rounding off connection or inner wall 213a and bottom wall 213b between right angle transition connection.The cross section of groove 213 refers to recessed
Section of the slot 213 on X-Z plane.
In other optional embodiments, as shown in figure 8, the cross section of groove 213 is V-shaped, including with predetermined angle
Two inner wall 213a interconnected.
In other optional embodiment, as shown in figure 9, the cross section of groove 213 is arc-shaped, have by first surface
The 211 arc bottom wall 213b formed towards the recess of second surface 212.
It is understood that the shape of groove 213 is not limited only to this, such as groove 213 can also be that other are irregular
Shape will not enumerate herein, as long as groove 213 is to be formed by first surface 211 towards the recess of second surface 212, groove
213 can increase the distance between first surface 211 and butt weld 140.
The utility model can be realized in other specific forms, without departing from its spirit and essential characteristics.For example, specific
Algorithm described in embodiment can be modified, and system architecture is without departing from the essence spirit of the utility model.Cause
This, current embodiment is all counted as being exemplary rather than in all respects limited, and the scope of the utility model is by institute
