Technical field
The utility model relates to the battery pack technical field, relates in particular to a kind of window frame structure of battery pack.
Background technology
Under the huge challenge gone from bad to worse at Present Global energy shortage and environment, Development of EV, realize the zero discharge of energy source of car dynamical system, and what promote electric automobile has universally formed extensive common recognition in the world.Battery of electric vehicle is the essential elements of electric automobile, and battery of electric vehicle is assembled by a plurality of battery modules, therefore the stability of single battery module has determined the performance of electric motor car.
With reference to Fig. 1, the battery of electric vehicle module generally comprises end plate 1, side plate 2, battery 31 etc.
Usually between end plate 1 and battery 31, battery 31 and battery 31, by structure glue 4, undertaken bondingly, use structure glue 4 is carried out bonding based on following reason:
1, by using structure glue 4 to make end plate 1, battery 31 be bonded into and be integrated, thereby avoided the vibrations in the driving process to cause battery 31 collecting together in module, collected together and will cause battery 31 loose contacts, short-circuit fire ultimate failure.More particularly, the phenomenon that electric motor car there will be battery modules to shake with automobile in traveling process, when in module, each assembly just combines by extrusion friction power, battery 31 is unfixing in the position of module the inside, thereby relative friction phenomenon appears, in the course of time battery 31 will there will be loose contact, will cause the serious security incidents such as short-circuit fire when serious.Therefore, need to be at end plate 1 and battery 31,31, battery 31 and battery increase structure glue 4 and are adhesively fixed, and make end plate 1, battery 31 form one, to guarantee battery 31, in the position of module the inside, fix.
2, structure glue 4 forms tough and tensile elastic material after solidifying, and can effectively cushion the impact that the fluctuation that occurs in electric motor car driving process causes the battery 31 in battery modules.
But, end plate 1 and 31 gluing connection technologies of battery of existing battery modules at least have following defect: the inner surface of end plate 1 can be stained with some organic pollutions, tiny metal fillings, greasy dirt etc. through operation rear surfaces such as machine work, transportation, storages, these pollutants can react with structure glue 4 or cause structure glue 4 to be mixed with impurity, weaken the adhesive strength of structure glue 4; The surface of end plate 1 is smooth flat face, structure glue 4 is little with the bonded area of end plate 1,1 bonding force deficiency of structure glue 4 and end plate can cause structure glue 4 and end plate 1 to occur when driving repeatedly after vibrations, degumming phenomenon occurring, and then causing battery 31 phenomenon to occur collecting together, the phenomenons such as battery 31 loose contacts and battery 31 inefficacies, short-circuit fire will appear when serious.
The utility model content
In view of the problem existed in background technology, the purpose of this utility model is to provide a kind of window frame structure of battery pack, and it can improve the end plate of battery modules and the gluing relay between battery.
In view of the problem existed in background technology, another purpose of the present utility model is to provide a kind of window frame structure of battery pack, and it can improve the security performance of battery, the useful life of prolongation battery.
To achieve these goals, the utility model provides a kind of window frame structure of battery pack, and it comprises: two end plates, lay respectively at two of battery pack stacking direction, and the battery that wherein battery pack scribbles structure glue by a plurality of lists or two front side stacks gradually and forms; And two side plates, lay respectively at the both sides of the battery pack of two end plates and overlap and weld with two end plates, to form window frame structure; Wherein, the inner surface of end plate is coarse and clean inner surface before gluing.
The beneficial effects of the utility model are as follows:
The inner surface of end plate adopts coarse and clean surface, efficiently solve the bonding hypodynamic problem of structure glue between end plate and battery, avoided that the inner surface of end plate is too smooth to be caused bond area not and exist impurity to cause the bonding hypodynamic problem of structure glue, avoid structure glue and end plate repeatedly after vibrations, degumming phenomenon to occur when driving, thereby reduce the risk that phenomenon appears collecting together in battery, improve the useful life of the stability of battery, the security performance that improves battery, prolongation battery.
