Description
Technical field
The utility model is related to a kind of electric automobile battery boxes, belong 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 vehicle, for
The performance of electric vehicle has a very big impact, and existing battery case is welded by sheet metal bending, and hangers is assembled in both sides, adds
It is connect with automobile chassis after upper cover, needs when due to installation, in four weekly assemblies assembly 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 because of welding deformation and aluminium block due to side plate；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, the design and use requirement of babinet is cannot be satisfied.
Invention content
In view of the above-mentioned problems existing in the prior art, the purpose of this utility model is to obtain a kind of electric automobile battery box.
For achieving the above object, the technical solution for the electric automobile battery box that the utility model uses is as follows：
Battery case includes four side plates and a bottom plate, and at least side plate is equipped with plug connector boss in four side plates, is set on boss
Press grommet nut column, and the grommet nut column that presses is set to the quadrangle of boss, the depth of boss be more than plug connector contact surface 3~
5mm。
Preferably, the side plate of offside is equipped with hangers, and babinet is connect 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, several reinforcing ribs are equipped in battery case.
Preferably, boss can be controlled in 0.1~0.3mm by grinding tool compression moulding, tolerance.
Compared with prior art, the utility model avoids the making shape of plug connector installation site using the setting of boss
Become, and be used cooperatively with the grommet nut that presses, the deformation quantity very little for the babinet for being, tolerance can be controlled in 0.1~0.3mm, loads onto
It is fitted closely with plug connector plane after plug connector, the sealing ring on plug connector eliminates micro deformation；It presses on boss blind
Hole Nut column, with screw, when connecting plug connector, Impact direction makes plug connector and box side compress fitting reliably, air-tightness
Test passes.Boss in the utility model is applicable to all types of and specification battery case, and the size and depth of boss can be with
Die sinking preparation is carried out according to the needs of plug connector, there is good extending space.
Description of the drawings
Fig. 1 is the structural schematic diagram of electric automobile battery box provided by the utility model；
Fig. 2 is the enlarged diagram of boss provided by the utility model.
Specific implementation mode
Electric automobile battery box provided by the utility model is made further to say in detail, completely with reference to embodiment
It is bright.The embodiments described below is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model
Limitation.
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 on side plate 1, for assembling all kinds of plug connectors.Battery case is by sheet metal
It welds and is 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 several reinforcing ribs 5, reinforcing rib 5, which not only acts as, increases 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 utility model need install plug connector position boss 4, the depth and appearance and size of boss 4 are stamped out by grinding tool
More than 3~5mm of contact surface of plug connector, usual thickness is the steel plate of 1.5mm, and boss height is 2.5mm~5mm.This practicality is new
Boss is punched on two shorter side plates in type, 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 mold, and tolerance can be controlled in 0.1~0.3mm, load onto after plug connector with insert
Fitting plane fits closely, and the sealing ring on plug connector eliminates micro deformation.Press grommet nut column 41 on boss, blind
Hole Nut column 41, which presses, to be fixed on boss, not only need not punching influences the air-tightness of battery case again on boss again, also not
Secondary pressure can be generated to the side plate of boss during plug connector assembles, lead to side plate deformation or gas leakage, with screw even
It is reliable so that plug connector and box side compress fitting for Impact direction when patching fitting.
The structure of boss and the grommet nut column that presses in the utility model can be adapted for any required installation plug connector
But timber intensity is insufficient or has in the babinet of air-tightness requirement, planar structure, and the mold of boss can be according to the size of plug connector
It is adjusted with the intensity of plank, this will not be repeated here.
It is it is necessary to described herein finally：Above example is served only for making the technical solution of the utility model further
It explains in detail, should not be understood as the limitation to scope of protection of the utility model, those skilled in the art is new according to this practicality
Some nonessential modifications and adaptations that the above of type is made belong to the scope of protection of the utility model.
