Abstract
The utility model relates to a strenghthened type power battery wraps assembly, including battery module frame, the electric core of soft package and busbar, the electric core of soft package is installed in battery module frame, the busbar sets up in battery module frame top the busbar top still is equipped with a copper bar of taking U type hole, utmost point ear on the electric core of soft package is bent on the busbar, and the back is under U type hole. The utility model discloses it is more firm to make each structure of whole battery package, avoided the battery package in long -time the use, the tab fracture that the vibration brought perhaps comes off, increased the area of contact of tab with busbar, the effectual contact resistance that has reduced gives the battery band next influence, installed the one deck copper bar and played the effect that anchor clamps compressed tightly among the welding process on tab.
Description
Technical field
The utility model relates to a kind of electrokinetic cell bag assembly, particularly relates to a kind of reinforced electrokinetic cell bag assembly, belongs to lithium battery PACK technical field.
Background technology
Along with the progress of technology, the application of lithium-ion power battery system is more and more extensive, and more and more higher to the safety requirements of lithium-ion power battery system, resultant connection fastening security problem can not be ignored.The power brick of present stage, current most scheme is all Tab(soft pack cell lug) bending is attached to Busbar(bus-bar) upper directly welding, this scheme often shakes the problems such as the syndeton brought is unreliable at use procedure electrokinetic cell in car load uses, keep away unavoidable not prison welding to come off from Busbar by Tab
A kind of electrokinetic cell method for fastening connection of the utility model provides a solution with regard to the problems referred to above, can effectively overcome, and has feasibility and the applicability of height.
Utility model content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art, and the utility model provides a kind of reinforced electrokinetic cell bag assembly, solves electrokinetic cell connection anti-loose, security problems.
For achieving the above object, the technical solution adopted in the utility model is: a kind of reinforced electrokinetic cell bag assembly, comprise battery modules framework, soft pack cell and bus-bar, described soft pack cell is arranged in battery modules framework, described bus-bar is arranged on above battery modules framework, is also provided with the copper bar in a U-shaped hole of band above described bus-bar; Lug bending on described soft pack cell on the busbar, after be in immediately below U-shaped hole.
Improve further as the utility model, described bus-bar and copper bar are bolted on battery modules framework.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
(1) make each structure of whole power brick more firm;
(2) avoid power brick in long-time use, vibrate the Tab brought and rupture or come off;
(3) add the contact area of Tab and Busbar, effectively decrease the impact that contact resistance brings to power brick;
(4) effect that one deck copper bar serves clamp pressing in welding process has been installed on Tab.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of reinforced electrokinetic cell bag assembly of the present utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
One described in the utility model reinforced electrokinetic cell bag assembly as shown in Figure 1, comprise battery modules framework 1, soft pack cell 2 and bus-bar 3, described soft pack cell 2 is arranged in battery modules framework 1, described bus-bar 3 is arranged on above battery modules framework 1, is also provided with the copper bar 5 in a U-shaped hole 4 of band above described bus-bar 3; Lug 6 bending on described soft pack cell 2 is smooth to be closely attached on bus-bar 3, after be in immediately below U-shaped hole 5; Copper bar 5 is pressed on lug 6 and also locks with bolt 7.Finally aim at U-shaped hole 4 on copper bar 5 from inner soldering polar ear 6 by Laser Welding, thus the Tab effectively preventing battery from bringing in vibration comes off.
Below be only embody rule example of the present utility model, protection range of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
Claims (2)
1. a reinforced electrokinetic cell bag assembly, comprise battery modules framework, soft pack cell and bus-bar, it is characterized in that: described soft pack cell is arranged in battery modules framework, described bus-bar is arranged on above battery modules framework, is also provided with the copper bar in a U-shaped hole of band above described bus-bar; Lug bending on described soft pack cell on the busbar, after be in immediately below U-shaped hole.
