Specific embodiment
It is described in detail cover assembly according to the present utility model and battery modules with reference to the accompanying drawings.
Illustrate the cover assembly 2 of the utility model first aspect first.
Referring to figs. 1 to Fig. 9, cover assembly 2 according to the present utility model includes: cover board 21, is had in height direction H
The first side (i.e. the front of cover board 21) and second side opposite with the first side (i.e. the back side of cover board 21)；Multiple busbars
22, it is fixed on cover board 21；And covering element 23, cover each busbar 22.Wherein, cover board 21 is provided with multiple first through hole
211, cover board 21 is penetrated through along height direction H respectively；And the first groove 21A, it is formed in the first side of cover board 21 and is connected to pair
The first through hole 211 answered.The multiple busbar 22 is fixed on second side of cover board 21, and at least part of each busbar 22 is revealed
For corresponding first through hole 211.Covering element 23 is at least accommodated and is fixed in the first groove 21A of cover board 21, to cover
The part for being exposed to corresponding first through hole 211 of each busbar 22.
In cover assembly 2 according to the present utility model, since each busbar 22 is fixed on second side of cover board 21, thus
Cover board 21 can guarantee that each busbar 22 is firmly fixed, and thereby ensure that the fixation reliability of each busbar 22.And due to
Cover board 21 is formed with the first groove 21A of receiving covering element 23, causes cover board 21 and covering element 23 whole along height in this way
Thickness on the H of direction is small；Simultaneously because covering element 23 only need to cover each busbar 22 be exposed to corresponding first
The part of through-hole 211 thereby reduces the overall volume of covering element 23 without the entire cover board 21 of covering, thus
Cover assembly 2 is small in size, light-weight.When cover assembly 2 is applied in battery modules, the first through hole 211 of cover board 21 is convenient for
Welding between each busbar 22 and corresponding battery, and the use of cover assembly 2 reduces the overall dimensions of battery modules, mitigates
The weight of battery modules, which thereby enhances the energy density of battery modules, reduces the manufacturing cost of battery modules.
In order to maximally reduce thickness of the cover assembly 2 in height direction H, the first groove 21A is in height
Depth on the H of direction is not less than thickness of the covering element 23 in height direction H, i.e. covering element 23 does not protrude from cover board 21
First side.
The the first groove 21A and/or busbar that fixed glue (such as double-sided adhesive) is adhered to cover board 21 can be used in covering element 23
22 part that cover board 21 is exposed to via first through hole 211.Wherein, in order to improve fixed glue in covering element 23 and cover board
21, the bonding force between busbar 22, it is necessary to assure the cleannes of the inner surface of the surface of busbar 22 and the first groove 21A,
The use temperature of fixed glue is noted also simultaneously.
In one embodiment, the first groove 21A can be multiple, and each first groove 21A can only be connected to one first corresponding
Through-hole 211, covering element 23 and the first groove 21A are quantitatively consistent.In other words, the first groove 21A and covering element 23
It is one-to-one relationship with first through hole 211.
In another embodiment, referring to figs. 1 to Fig. 4, the multiple first through hole 211 can in the width direction W be arranged in
Few two rows, and L is spaced apart multiple first through hole 211 of the same row on width direction W along its length.Correspondingly,
One groove 21A can be at least two, and the interval W is arranged at least two first groove 21A in the width direction, and each first groove
L extends with the multiple first through hole 211 for the same row being connected on width direction W 21A along its length.
In this embodiment, covering element 23 and the first groove 21A quantitatively can be consistent, due to each first groove 21A
It is connected to multiple first through hole 211 simultaneously, thus the first groove 21A and covering element 23 and first through hole 211 are not an a pair
The relationship answered.Referring to Fig.1, size of all parts on length direction L of each covering element 23 on width direction W can
Unanimously, each covering element 23 can be the rectangular structure of strip at this time.
In order to save the material of covering element 23 and mitigate the weight of covering element 23, referring to Fig. 6, each covering element 23 can
Multiple shielding parts 231 are included, the interval L is arranged along its length, and each shielding part 231 covers being exposed to for corresponding busbar 22
The part of corresponding first through hole 211；And multiple interconnecting pieces 232, the interval L is arranged along its length, and each interconnecting piece 232 connects
Two adjacent shielding parts 231, and size of each interconnecting piece 232 on width direction W is less than shielding part 231 in width direction W
On size.
In this embodiment, covering element 23 and the first groove 21A quantitatively can be inconsistent, and due to each first groove
21A is connected to multiple first through hole 211 simultaneously, thus the first groove 21A, covering element 23 and first through hole 211 are not
One-to-one relationship.Referring to Fig. 8, covering element 23 can include the first receiving portion 233, and the interval W is arranged and receives in the width direction
It is dissolved in the first groove 21A；And second receiving portion 234, connect two adjacent the first receiving portions 233.Wherein, due to width
Two adjacent the first receiving portions 233 are linked into an integrated entity by the second receiving portion 234 on the W of direction, thereby reduce cover assembly 2
The quantity of components improves the packaging efficiency of cover assembly 2.
