The invention belongs to new-energy automobile power battery packet technology field, more particularly to a kind of for new-energy automobile
Battery pack box.
Background technology
New-energy automobile is quickly grown at present, and use is increasingly universal.New-energy automobile generally uses power battery pack conduct
Power resources, battery pack box mainly install the parts such as battery modules, electrical part and upper shell.As it can be seen that battery pack box is power electric
The main carrying of Chi Bao and seal structural part.
The battery pack box of existing new-energy automobile power battery packet uses metal plate welding structure, material to be generally thickness 1-
The steel plate of 2mm, after one or more sheet bending, lap-joint is connected using carbon dioxide gas arc welding or spot welding,
Seam crossing plays fluid sealant closing.On battery pack box for upper shell, battery modules and electrical part installation point, need welded nut or
Metal plate holder.Battery pack box welding rear surface need to make rust preventive paint processing.
The welded battery pack box of above-mentioned metal plate has following problem：
(1) battery pack box is made of bending and forming, butt welding process, and consistency is poor, and battery modules, electrical part are susceptible to dress
With defect, mass production needs cannot be met.
(2) battery pack box and left and right rear hanger are integral solder structure, when power battery pack dismounting is repaired, rear hanger and bottom
The front and back interference of disk rear suspension, need to first dismantle rear suspension dismounting cell packet again, and battery pack installs rear suspension, vehicle after entrucking again again
Four-wheel aligner need to be readjusted.There is dismounting difficulty, the costly problem of maintenance man-hours in battery pack.
(3) there are multiple weld seams, flatness is bad for battery pack box and upper shell faying face, upper, battery pack box faying face is close
It is poor to seal reliability.
(4) battery pack box and electrical connector mating surface are there are local welding deformation, sealing reliability after connector installation
Difference.
(5) battery pack box uses metal plate welding structure, and structural manufacturing process is complicated, and cost of parts is higher.
(6) battery pack cassette bottom portion is smooth sheet metal structural, in order to effectively reduce road gallet to power battery pack bottom
Impact failure risk, it usually needs increase battery pack box metal plate reinforcer, enhance the strength and stiffness of battery pack box with this,
So that battery pack box overall weight is bigger than normal, it is unsatisfactory for the requirement of new-energy automobile light-weight design.
And Chinese patent CN201621071957.6 disclose a kind of Vehicular battery packet lower housing structure, battery pack housing and
Battery pack, the Vehicular battery packet lower housing structure include the lower housing of upper opening, and the bottom of the lower housing is provided with bumps
Structure, the concaveconvex structure include multiple boss of alternate setting and multiple grooves.The Vehicular battery packet lower casing of the utility model
The bottom of body structure, lower housing is provided with concaveconvex structure, and concaveconvex structure includes multiple boss of alternate setting and multiple grooves, phase
For the lower housing that existing lower housing bottom is smooth sheet metal structural, in the case where not increasing case material thickness, bottom
Portion has the intensity and rigidity that the lower housing of the concaveconvex structure can enhance lower housing, effectively reduces road gallet to power battery
Wrap bottom impact failure risk, it can be achieved that battery pack high intensity, light-weight design requirement, can meet power battery pack vibration,
Impact test requirement.
For above-mentioned patent still using sheet metal structural, manufacturing process generally comprises cutting, punching, curved molded etc.,
These mode process are slow, and yields is low.Material and manufacture work of the our company for battery pack lower housing, that is, battery pack box thus
Skill is adjusted, and is integrally formed battery pack box in the form of molten aluminum casting, and be adjusted to its internal structure, is increased aluminium
The mechanical performance of battery pack box processed.
