Description
Technical field
The present invention relates to a kind of electric automobile battery box, belongs to new-energy automobile field.
Background technology
Electric automobile battery box is the storage place of batteries of electric automobile, is the power support structure of electric automobile, for
The performance of electric car has a very big impact, and existing battery case is welded by sheet metal bending, and both sides assembling hangers, adds
It is connected after upper cover with automobile chassis, needs during due to installation, in four weekly assemblies assembling high pressure plug connector, the MSD plug connectors of babinet
Deng, punching is needed on babinet, but existing technique is that the aluminium block of one piece of 2.5~5.0mm of sealing glue is used on plug connector hole,
Plug connector is connected by screw with aluminium block and babinet；It cannot be bonded completely after being pasted due to side plate because of welding deformation, and aluminium block；Case
Side plate is connected with aluminium sheet and plug connector using weldering screw is planted, and existing punch structure and technique frequently result in box side change
Property, the air-tightness of babinet is influenced, can not meet the design and use requirement of babinet.
The content of the invention
In view of the above-mentioned problems existing in the prior art, the purpose of the present invention is obtain a kind of electric automobile battery box.
For achieving the above object, the technical solution for the electric automobile battery box that the present invention uses is as follows：
Babinet includes four side plates and a bottom plate, and at least side plate is equipped with plug connector boss in four side plates, and boss is equipped with
Press grommet nut column, and the grommet nut column that presses is arranged on the corner of boss, and the depth of boss is more than 3~5mm of plug connector contact surface.
Preferably, the side plate of offside is equipped with hangers, and babinet is connected after adding lid with automobile chassis.
Preferably, battery case is made of sheet metal, the long 2529mm wide 983mm high 166mm of babinet.
It is furthermore preferred that the long lateral plates of babinet are equipped with hangers, being rushed on short side plate has boss.
It is furthermore preferred that sheet metal is the steel plate of 1.5mm and/or the aluminium alloy plate of 3mm.
Preferably, some reinforcing ribs are equipped with battery case.
Preferably, boss is compressing by grinding tool, and tolerance can be controlled in 0.1~0.3mm.
Compared with prior art, the present invention avoids the making deformation of plug connector installation site using the setting of boss, and
Grommet nut is used cooperatively with pressing, and the deformation quantity very little for the babinet for being, tolerance can be controlled in 0.1~0.3mm, loads onto plug connector
Fitted closely afterwards with plug connector plane, the sealing ring on plug connector eliminates micro deformation；Press grommet nut on boss
Column, with screw, when connecting plug connector, Impact direction causes plug connector and box side to compress fitting reliably, and air tightness test closes
Lattice.Boss in the present invention is applicable to all types of and specification battery case, and the size and depth of boss can be according to plug connectors
Needs carry out die sinking preparation, there is good extending space,
Brief description of the drawings
Fig. 1 is the structure diagram of electric automobile battery box provided by the invention；
Fig. 2 is the enlarged diagram of boss provided by the invention.
Embodiment
Electric automobile battery box provided by the invention is made with reference to embodiment further in detail, intactly to illustrate.Under
The embodiment of face description is exemplary, and is only used for explaining the present invention, and is not considered as limiting the invention.
Electric automobile battery box as shown in Figure 1, surrounds a closed babinet, in an offside by four side plates 1 and a bottom plate 2
Side plate 1 be equipped with hangers 3, plug connector hole is additionally provided with side plate 1, for assembling all kinds of plug connectors.Battery case is by sheet metal
Weld and be made, the long 2529mm wide 983mm high 166mm of the babinet by bending, sheet metal is specially the steel plate of 1.5mm thickness
And/or the aluminium alloy plate of 3.0mm thickness, bottom plate and side plate are equipped with some reinforcing ribs 5, reinforcing rib 5 not only acts as increase intensity
Effect, is also fixedly installed in battery case for battery and provides fixed position.
As shown in Fig. 2, in order to ensure that plug connector has good grafting effect, while to the airtight of battery case after grafting
Property.The present invention stamps out boss 4 in the position for needing to install plug connector by grinding tool, and the depth and appearance and size of boss 4 are more than
3~5mm of contact surface of plug connector, usual thickness are the steel plate of 1.5mm, and boss height is 2.5mm~5mm.Will be convex in the present invention
Platform is punched on two shorter side plates, and longer two side plates are equipped with hangers 3.It is stamping by rigid die, therefore boss
Deflection very little, and flatness is ensured by mould, tolerance can be controlled in 0.1~0.3mm, load onto after plug connector with plug connector plane
Fit closely, the sealing ring on plug connector eliminates micro deformation.Press grommet nut column 41 on boss, grommet nut column
41, which press, is fixed on boss, need not only punch the air-tightness for influencing battery case on boss again again, will not be in grafting
Secondary pressure is produced to the side plate of boss during part assembling, causes side plate deformation or gas leakage, with screw in connection plug connector
When Impact direction make it that plug connector and box side compress fitting reliable.
The structure of boss and the grommet nut column that presses in the present invention can be adapted for any required installation plug connector palette
Material intensity deficiency has in the babinet of air-tightness requirement, planar structure, and the mould of boss can be according to the size and plate of plug connector
The intensity of material is adjusted, and this will not be repeated here.
Finally be necessary described herein be：Above example is served only for making technical scheme further detailed
Ground explanation, it is impossible to be interpreted as limiting the scope of the invention, those skilled in the art's the above according to the present invention
Some the nonessential modifications and adaptations made belong to protection scope of the present invention.
