Description
Technical field
Electric automobile field is the utility model is related to, more particularly to a kind of battery for electric automobile case.
Background technology
At present, since existing battery for electric automobile cassette frame is welded by sheet metal component group, welding capacity is big, yielding,
And craftsmanship is poor；Usually all it is to use thicker plate and battery case cover board is then for enough intensity, heavier mass.
The content of the invention
The utility model aim is：In view of the deficiencies of the prior art, a kind of battery for electric automobile case is proposed, which exists
While ensureing that battery for electric automobile case can be installed smoothly, additionally it is possible to improve the strength and stiffness of whole babinet, alleviate
The weight of battery case cover board.
The technical solution of the utility model is：A kind of battery for electric automobile case, including the battery case for storage battery
The battery case cover board of framework and capping battery cassette frame, the battery cassette frame weld structure by some aluminium section bars overlapped successively
Into the battery case cover board includes inner panel and outside plate, is stamped and formed out using double-layer aluminium alloy.
The utility model based on the above technical solutions, further includes following preferred solution：
The aluminium section bar of the battery cassette frame uses the aluminium section bar of extruding-out process.
Each aluminium section bar overlap of the battery cassette frame is welded using aluminium alloy arc welding process.
Fluid sealant is scribbled on the inside of the battery cassette frame.
The reinforcing rib of aluminium section bar is additionally provided with the outside plate of the battery case cover board, between the outside plate and inner panel, reinforcing rib
Welded using the spot-welding technology of aluminium alloy.
Rectangular preiection array is stamped and formed out on the battery case cover board, formed with circular groove array on rectangular preiection.
Round hole is provided with the reinforcing rib.
Circular groove array flush on the position and inner and outer plates of the round hole.
Pass through the fixation that is spirally connected between the battery case cover board and battery cassette frame.
The utility model has the advantages that：
Battery for electric automobile case provided by the utility model, can smoothly be installed in guarantee battery for electric automobile case
While, the battery inside battery cassette frame can be more effectively protected along band, mitigates total quality, additionally it is possible to improve whole case
The strength and stiffness of body.
Brief description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment
The attached drawing used is briefly described, and drawings in the following description are only some embodiments of the present invention, general for this area
For logical technical staff, without creative efforts, other attached drawings can also be obtained according to these attached drawings.
Fig. 1 is battery case structure diagram in the utility model embodiment；
Fig. 2 is the utility model battery cassette frame exploded perspective view；
Fig. 3 is the utility model battery case cover board exploded perspective view.
Embodiment
Such scheme is described further below in conjunction with specific embodiment.It is to be understood that these embodiments are to be used to illustrate
The utility model and be not limited to limitation the scope of the utility model.The implementation condition used in embodiment can be according to specific producer
Condition do further adjustment, the implementation condition being not specified is usually the condition in normal experiment.
Fig. 1-3 shows a specific embodiment of the mounting structure of this battery for electric automobile case of the utility model.
As shown in Figure 1, it includes for the battery cassette frame 1 of storage batteries and the battery case cover board 2 for covering framework.
As shown in Fig. 2, the battery cassette frame 1 is formed by welding by some aluminium section bars overlapped successively, the aluminium section bar is equal
Using the aluminium section bar of extruding-out process, each aluminium section bar overlap is welded using aluminium alloy arc welding process, the battery after welding
Fluid sealant is coated on the inside of cassette frame.
As shown in figure 3, the battery case cover board 2, including the inner panel 21 and outside plate 22 being stamped and formed out using double-layer aluminium alloy,
22 reinforcing rib 23 and reinforcing plate 24 for being additionally provided with aluminium section bar on outside plate, has been stamped and formed out rectangular preiection battle array on the battery case cover board
Row, formed with circular groove array on rectangular preiection, are provided with round hole on the reinforcing rib 23, the position of round hole with it is inside and outside
Circular groove array flush on plate.
The key improvements of the present embodiment are：The mixing material used relative to the battery cassette frame of conventional electric automobile is welded
Connect and form, this framework is all that welding is less, and process is simple using the structure of same aluminium section bar extrusion.And battery case cover board is then
Using aluminum alloy double-layer stamping technology, allow cover board in itself in the case of proof strength, weight can be mitigated.
Compared with existing structure, formed because the battery cassette frame in this implementation is overlapped by aluminium section bar, fluid sealant is coated in inside；
Cover board is divided into inner panel and outside plate two parts, using aluminum alloy double-layer stamping technology.Cover board and framework be using being spirally connected at the same time, can be compared with
Few manufacturing procedure.
And in the present embodiment, all material used is aluminum.It was overlapped to form before this with the aluminium section bar of extrusion molding
Framework, overlap use aluminium alloy arc-welding, and fluid sealant is coated in inside.Secondly, battery cassette frame is by two pieces of aluminium sheet punch formings,
Plus aluminium section bar reinforcing rib, aluminium alloy pinpoint welding is used together.Last battery case cover board is then connected with framework using rivet nut.
Certainly, above-described embodiment is only to illustrate the technical concepts and features of the utility model, and its object is to allow people's energy
The content of solution the utility model much of that is simultaneously implemented according to this, can not limit the scope of protection of the utility model with this.It is all according to this
The equivalent transformation or modification that the Spirit Essence of utility model main technical schemes is done, should all cover the protection in the utility model
Within the scope of.
