The application is described in further detail below by specific embodiment and with reference to accompanying drawing.
As shown in Figures 1 to 7, the embodiment of the present application provides a kind of battery modules 1, and it includes at least one battery core unit
10, the battery core unit 10 includes fixed frame 100 and at least one battery core 101, and the fixed frame 100 has battery core installation cavity 100a,
And battery core 101 can be arranged in battery core installation cavity 100a, to realize that the installation of itself is spacing, wherein, also opened on the fixed frame 100
Provided with the lug spacing hole 100b being connected with battery core installation cavity 100a, when battery core 101 is arranged in battery core installation cavity 100a,
The lug 101a of the battery core 101 can stretch out from lug spacing hole 100b, and can be with other battery cores in the battery modules 1 pole
Ear is welded.
, can be in fixed frame 100 by setting lug spacing hole 100b on fixed frame 100 in the present embodiment
The lug 101a of battery core 101 carry out spacing, caused with alleviating because the lug 101a of battery core 101 is softer between each battery core 101
Lug 101a weld relatively difficult situation, so as to reduce in battery modules 1, groups of technique is difficult between each battery core 101
Degree, improves the group efficiency of battery modules 1.
Preferably, as shown in Fig. 3 to Fig. 7, above-mentioned battery core unit 10 may also include location division 102 and collector plate 103, and this is determined
Position portion 102, which protrudes, is arranged on fixed frame 100 on battery core installation cavity 100a face, and offers positioning hole on location division 102,
And a part for collector plate 103 is through positioning hole and can be electrically connected with lug 101a.In the present embodiment, by fixed frame
Location division 102 with positioning hole is set on 100, can not only realize that the quick positioning of collector plate 103 and fixed frame 100 is pacified
Dress, and because the location and installation of collector plate 103 is on fixed frame 100, therefore can also facilitate the collector plate 103 with it is spacing from lug
The lug 101a that hole 100b stretches out is welded.
What deserves to be explained is, the location division 102 can be molded with the integral molded plastic of fixed frame 100, can also be welded by welding procedure
It is connected on fixed frame 100.
Further, one end of above-mentioned collector plate 103 is end, and the end passes through positioning hole, and collector plate 103 is another
Hold as head end, wherein, as shown in fig. 7, the end of collector plate 103 is provided with overhead structure 103a, overhead structure 103a has
Elasticity, when overhead structure 103a enters positioning hole, the extruding force that overhead structure 103a is applied by the hole wall of positioning hole
And elastic deformation is produced, when overhead structure 103a is passed from positioning hole, overhead structure 103a replys deformation, and can be with
The face away from head end leans on location division 102, to reduce the probability that collector plate 103 departs from fixed frame 100, so as to ensure current collection
The mounting stability of plate 103 and fixed frame 100.In addition, when battery modules 1 include multiple battery core units 10, each battery core list
The head end of the collector plate 103 of member 10 can be electrically connected with the bus-bar 110 in battery modules 1, between achievable each battery core unit 10
Electrical connection.
In one embodiment of the application, as shown in Figures 3 to 6, above-mentioned location division 102 may include the width along lug
Direction spaced first locating piece 102a and the second locating piece 102b, the first locating piece 102a and the second locating piece 102b
The positioning hole passed through for collector plate 103 is offered, and along the width of lug, the upper directions second of the first locating piece 102a
It is more than or equal to pole towards the distance between the first locating piece 102a face on locating piece 102b face, with the second locating piece 102b
Ear 101a width, so design enable is positioned at the first locating piece from the lug spacing hole 100b lug 101a stretched out
Between 102a and the second locating piece 102b.
In the present embodiment, by setting the first locating piece 102a and the second locating piece 102b not only to improve collector plate
103 with the mounting stability of fixed frame 100, but also lug 101a can be facilitated to be welded with collector plate 103.Specifically, when from
The lug 101a that lug spacing hole 100b stretches out is bent to the direction where the first locating piece 102a and the second locating piece 102b, and
When being positioned between the first locating piece 102a and the second locating piece 102b, the end of the collector plate 103 can sequentially pass through first and determine
Position block 102a positioning hole and the second locating piece 102b positioning hole, after collector plate 103 is installed in place, on the collector plate 103
Part between the first locating piece 102a and the second locating piece 102b can be welded with lug 101a.

Portion 104 so that what the lug 101a after bending can be smooth is overlapped on the lug clinch 104, is easy to subsequently and collector plate
The lug of 103 or other battery cores is welded.And because the lug 101a being overlapped on lug clinch 104 is more smooth,
Even if after welding, being also not easy the situation for weld cracking occur, so as to improve the soldering reliability of lug.
It should be noted that deviate from the face of fixed frame 100 on the lug clinch 104, it is remote compared to above-mentioned positioning hole
The inner surface of fixed frame 100 can avoid collector plate 103 when through positioning hole and lug closer to fixed frame 100, so design
The situation that clinch 104 is interfered, so as to ensure that it is fixed that collector plate 103 can be realized through positioning hole and with fixed frame 100
Install position.
Preferably, as shown in figure 5, above-mentioned lug clinch 104 extends to the second locating piece from the first locating piece 102a
102b, so design can ensure that the lug 101a being located between the first locating piece 102a and the second locating piece 102b can take completely
It is connected on lug clinch 104, it is to avoid because a lug 101a part is hanging between locating piece and lug clinch 104,
Lug 101a is caused easily to be shaken in welding process, so as to influence the situation of welding effect.
