Description
Technical field
This utility model belongs to electric automobile field, particularly relates to a kind of power battery of electric vehicle box device.
Background technology
At present, the set of cells of electric automobile is relatively big due to weight, is therefore typically mounted on car floor position, thus reduces the position of centre of gravity of automobile, to reach preferably riding stability.It is currently used for installing and deposits the battery case of set of cells and be typically designed to regular shape such as cuboid, manufacture and design to facilitate, complex yet with car floor locational space, so regular shape is unable to reach bigger parking space, and easily cause set of cells in the vertical direction and take larger space, so that position of centre of gravity is the highest, nor the heat radiation of beneficially set of cells.
Utility model content
This utility model is to overcome deficiency of the prior art, it is provided that a kind of effective reduction set of cells position of centre of gravity, for set of cells provide bigger installing space power battery of electric vehicle box device.
To achieve these goals, this utility model is by the following technical solutions:
A kind of power battery of electric vehicle box device, including lid and base arrangement, described lid includes the first storage end and pancake second storage end, described base arrangement includes first base plate corresponding with the first storage bottom portion and second base plate corresponding with the second storage bottom portion, the edge of the edge of described lid and the first base plate, the second base plate is fixing to be connected, the first described base plate and the contact side of the second base plate have lap, and the lower section of base arrangement is provided with the base plate stiffener covering lap.Being set of cells in first storage end and the second storage end and provide installing space, set of cells quantity is greatly increased.Set of cells can tile along car floor so that the position of centre of gravity of set of cells reduces.After being divided into two by base arrangement, the set of cells of the first storage end and the second storage end can independently be changed so that detect and maintenance becomes more convenient.
As preferably, the lower section of the second described base plate is provided with some second base plate stiffeners, and the second base plate stiffener is arranged in parallel with base plate stiffener, and the two ends of base plate stiffener, the two ends of the second base plate stiffener are equipped with installing hole.Second base plate stiffener is set, to improve rigidity and the intensity of battery case.
As preferably, being provided with backplate below the first described base plate, the first described base plate is provided with some strip bulges being arranged in parallel, and described backplate is provided with the groove matched with strip bulge.Backplate is set, it is to avoid base plate impact is directly caused damage by ground foreign material, handstone.
As preferably, described the first base plate, the second base plate use high-strength steel sheet to make.Such first base plate, the second foolrstiffness, intensity are preferable, to improve the support to internal battery and protected effect.
As preferably, described lid uses glass fibre to make.So its contour structures of lid is the compactest, reduces the total quality of battery case simultaneously, improves insulating properties.
The beneficial effects of the utility model are: (1) makes the distribution of set of cells relatively reasonable, reduces battery case center of gravity；(2) battery case integral rigidity and intensity are higher, preferable to the protective value of set of cells；(2) quality of battery case reduces, good insulating.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model；
Fig. 2 is explosive view of the present utility model；
Fig. 3 is polycrystalline substance schematic diagram of the present utility model.
In figure: lid 1, the first storage end 1a, the second storage end 1b, the second base plate 2, the first base plate 3, strip bulge 3a, lap 4, backplate 5, groove 5a, base plate stiffener 6, the second base plate stiffener 7, installing hole 8.
Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings.
In embodiment as shown in Figure 1, a kind of power battery of electric vehicle box device, including lid 1 and base arrangement.Wherein, lid uses glass fibre to make, and including the first storage end 1a and second storage end 1b two parts, wherein the volume of the first storage end is relatively big, can deposit more battery bag, and the second storage end is pancake, and the height of the first storage end is more than the second storage end.It is interconnected between first storage end and the second storage end.Lid is provided with the projection of strip in the centre of the second storage end so that lid can adapt with the base plate of electric automobile, to improve the compactedness of battery pack device.
Shown in Fig. 2, base arrangement includes first base plate 3 corresponding with the first storage bottom portion and second base plate 2 corresponding with the second storage bottom portion, and the first base plate, the second base plate use high-strength steel sheet to make.If the edge of the edge of lid and the first base plate, the second base plate connects by bolt stem is fixing.Shown in Fig. 3, the contact side of the first base plate and the second base plate has lap 4, the lower section of base arrangement is provided with the base plate stiffener 6 covering lap, base plate stiffener be respectively arranged at two ends with installing hole 8, first base plate and the second base plate are respectively equipped with the through hole corresponding with installing hole on the both sides of lap, and three can be fixed by bolt.
Shown in Fig. 2, Fig. 3, the lower section of the second base plate is provided with three the second base plate stiffeners 7, second base plate stiffener is arranged in parallel with base plate stiffener, and the two ends of the second base plate stiffener are equipped with installing hole, lid, the second base plate and the second base plate stiffener can be fixed installation by bolt.Being provided with backplate 5 below first base plate, the first base plate is provided with some strip bulge 3a being arranged in parallel, and backplate is provided with the groove 5a matched with strip bulge.
Battery pack device is positioned at car floor position after the installation is complete, contour structures is compact, position of centre of gravity is relatively low, its lid uses lightweighting materials glass fibre, alleviate the weight that battery case is overall, glass fiber material also has the advantage such as good insulating, thermostability is strong, corrosion resistance good, mechanical strength is high, low price simultaneously, and on the premise of ensureing battery pack device quality and ruggedness, manufacturing cost is substantially reduced.
