Background technology
Along with the aggravation of air environmental pollution, the requirement to motor vehicle fuel is more and more higher, electric automobile also conform to demand by
Gradually grow up.Electric automobile uses battery to provide the energy, and wherein battery is based on lithium battery.Lithium battery has energy density
High, output is big, average output voltage is high, good cycle, charge/discharge rates fast, operating temperature range width, service life
The advantages such as length, so lithium battery quickly grows in recent years.
But in the case of abnormal use or temperature are too high, there is the danger of blast in lithium battery, if used in electricity
Lithium battery on electrical automobile occurs blast then serious harm to ride the life security of personnel.But at present, cell box explosion preventing is normal
Often it is used only as " preventing trouble before it happens ", reduces the probability of accidental explosion i.e. as far as possible, as Chinese patent (CN103000837A) is public
Having opened a kind of anti-explosion battery box, this utility model reduces because jolting by being provided with antirattle spring in battery case Body Lumen
The situation of battery explosion occurring, but once explodes, this battery case does not has any protective effect at all.The most how to exist
Avoid loss during battery accidental explosion as far as possible, ensure the life security of personnel by bus, the most just become this area urgently to be resolved hurrily
Technical barrier.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of explosion-proof directional pressure venting type battery case, described battery
Box has the advantage such as light weight, good, the targeted release explosion energy of explosion-proof, it is possible to significantly improve the use safety of battery.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of explosion-proof directional pressure venting type battery case, is made up of box body and lid, and described box body and lid are bolted,
Hole is distributed on described box body, and described lid and box body port are obliquely installed, and described lid is angled with box body；Described
Lid is wrapped in curing molding on central layer by pitch based fiber and forms；Described box body is wrapped in core by pitch based fiber
On mould, curing molding forms.
Preferably, fiber used by described lid and box body is carbon fiber, glass fibre, aramid fiber or polyethylene fibre；
Described central layer is metal core board or quilted plastic panel, and described core is metal core die or plastics core；
Preferably, described resin is thermosetting resin or thermoplastic resin；
Further preferred, described thermosetting resin is epoxy resin, polyurethane resin or vinylite；Described heat
Plastic resin is polyethylene or polypropylene；
Preferably, when battery case is placed horizontally at bottom of car, between described lid and box body, angle is less than 90 °, then
The energy direction earthward that battery explosion produces is released；
It is further preferred that angle is 40 ° between described lid and box body.
Preferably, when battery case is placed horizontally at automobile top, between described lid and box body, angle is more than 90 °, then
Battery explosion energy releases above automobile top；
It is further preferred that angle is 135 ° between described lid and box body.
Preferably, a diameter of 1mm～5mm of described hole, it is used for dispelling the heat and connecting up, hole is crossed conference and is reduced the mechanics of box body
Performance, it is also possible to become the path that blast releases energy so that this battery case does not reaches the effect of directional pressure venting；Diameter is too small
It is unfavorable for passing through of battery line.
The beneficial effects of the utility model are:
1. this utility model uses System of Filament Winding Process to prepare box body and lid, it is possible to make each of battery case
There is continuous lod in direction, therefore has good mechanical property, and then plays explosion-proof effect.And appear in the newspapers at present
The chopped strand that fibre reinforced composites battery case uses strengthens or unidirectional fibre strengthens, and prepared by both modes compound
Material can alleviate the weight of conventional batteries box, but the intensity of chopped firbre reinforced composite is relatively low, and unidirectional fibre strengthens
Only higher in fiber axial direction intensity, other direction intensity is relatively low, so both fibre reinforced composites battery case bases
Originally it is difficult to play explosion-proof, and this utility model uses System of Filament Winding Process so that all directions of battery case have
Continuous lod, therefore has good mechanical property, and then plays explosion-proof, is also based on its good explosion-proof effect
Really so that explosion energy can only go out release from lid mouth, in conjunction with the angle design of lid Yu box body, thus reach directional pressure venting it
Purpose；
2. this utility model prepares battery case breaks through tradition, the most not as battery case lid exist
On, lid under pattern of vertically placing, but by battery case horizontal positioned.In conjunction with this utility model shape, structure peculiar
Design, can play good directional pressure venting effect when battery accidental explosion.Concrete, the lid of this utility model battery case
Be bolted with box body, and lid is obliquely installed with box body port, then lid and box body have certain angle；Work as electricity
Surprisingly there is explosion time in pond, can produce substantial amounts of energy, owing to the junction of lid and box body is to be bolted, and other
Position is all wound around fibre reinforced composites prepared by molding, therefore if it occur that the produced energy of blast is sufficiently large, and energy
Enough making bolt failure, lid comes off, and owing to box body has good explosion-proof effect, energy can only discharge at lid,
And by changing lid and the angle of box body, it is possible to control exergonic direction.When the battery of electric automobile is positioned over automobile
During bottom, the lid of the battery case now arranged and the angle of box body, less than 90 °, are affected by arranging angle, the energy that blast produces
Measure direction earthward to release, explosion time so occurs, also the personnel by bus above battery will not be brought excessive danger；Work as electricity
When the battery of electrical automobile is placed on automobile top, the lid of the battery case now arranged and the angle of box body, more than 90 °, once occur
Blast, owing to box body is by continuous lod, has explosion-proof, and explosion energy is from relatively weak bolt closure i.e. box
Gushing at body mouth, affected by arranging angle, explosion energy releases above automobile top, it is possible to ensure to ride below battery case
The personal safety of personnel.Meanwhile, on box body, the hole of distribution is arranged rationally, not only improves heat radiation and wiring, reduces simultaneously as far as possible
Effect on Mechanical Properties to box body.
In a word, this utility model reasonable in design, have that light weight, explosion-proof be good, directional pressure venting release explosion energy
Etc. advantage, it is possible to conscientiously improve the use safety of battery, support personnel's safety.
