Description
Technical field
The present invention relates to field of lithium.
Background technique
Correlative study shows that the every reduction 100Kg weight of new-energy automobile, course continuation mileage can promote 10%-11%.It can be with
Reduce 20% battery cost and 20% day-to-day loss cost.To vehicle body, dynamical system (engine, power battery) and bottom
The alternative materials use of disc system is current most important lightweight means.Vehicle body, power and transmission system, chassis and suspension system
System is three main component parts on automobile kerb weight, accounts for about 1/4 or so of complete vehicle quality respectively.In assurance function and
On the basis of safety, original material is replaced with the smaller material of density, is current most effective lightweight means.
In addition, with the formulation of electrokinetic cell system relevant criterion and specification, pushing technology in automobile batteries packet industry
Development, market requires the specific energy of electrokinetic cell system to be also higher and higher, application of the lightweight in electrokinetic cell system
It is also extremely urgent.
Summary of the invention
In order to solve the above-mentioned technical problems, the present invention provides a kind of lithium battery pack, including upper box, lower box, aluminium is closed
Metal type material frame assembly, lower box are located at below aluminum alloy frame assembly, are fixed by bolt and aluminum alloy frame assembly；Battery
Mould group is located in aluminum alloy frame assembly card slot and is fixed by bolt and aluminum alloy frame assembly card slot；Upper box is located at aluminium conjunction
The top of golden frame assembly is equally fixed by bolt and aluminum alloy frame assembly, which is characterized in that upper box, lower box by
The one or more materials of unsaturated-resin, aluminium hydroxide, glass fibre, styrene are formed by mould pressing process, aluminum alloy frame
Assembly is welded by differential profiles.
Further, the aluminum alloy frame assembly material is aluminium alloy 6063.
Further, a plurality of reinforcing rib is further respectively had on the upper box and the lower box.
Lithium battery pack of the invention effectively alleviates the weight of battery pack in the case where guaranteeing various aspects intensity requirement
Amount, improves the specific energy of battery system.
Detailed description of the invention
Fig. 1 is the schematic diagram of lithium battery pack of the invention.
Specific embodiment
The invention will be further described for specific embodiment with reference to the accompanying drawing.
Fig. 1 show lithium battery pack schematic diagram of the invention, and lithium battery pack of the present invention includes upper box 1, lower box 4, aluminium
Alloy profile frame assembly 2.Lower box 4 is located at 2 lower section of aluminum alloy frame assembly, solid by bolt 7 and aluminum alloy frame assembly 2
It is fixed；Battery modules 3 are located in 2 card slot of aluminum alloy frame assembly and are fixed by bolt and 2 card slot of aluminum alloy frame assembly；Top box
Body 1 is located at the top of aluminum alloy frame assembly 2, equally fixed by bolt 5 and aluminum alloy frame assembly 2.Aluminum alloy frame is total
It is spliced at 2 by various differential profiles, while profile external dimensions exact matching upper box 1 and lower box 4, so that aluminium alloy
Frame assembly 2 does not have displacement space in upper and lower box, while by bolt 6 that upper box 1 and lower box 4 is fixed, ensure that
Battery pack does not have any shaking space upper box 1, lower box 4 can be by unsaturated-resin, hydroxide in entire battery pack
The one or more materials of aluminium, glass fibre, styrene are formed by mould pressing process.It is additionally provided on upper box 1, lower box 4 a plurality of
Reinforcing rib, it is ensured that guarantee cabinet intensity under the premise of light-weighted.
2 material of aluminum alloy frame assembly is aluminium alloy 6063, passes through extrusion die extrusion molding.Aluminum alloy frame assembly 2
Preferably by three kinds of differential profiles by being welded into an entirety, differential profiles can according to need voluntarily select suitable profile into
Row is assembled, and welding is preferably TIG weldering (Tungsten Inert Gas Welding), also known as non-melt pole inert gas tungsten electrode
Protection weldering.Either in the stainless steel of human weld or automatic welding 0.5~4.0mm thickness, TIG weldering is all most commonly used
Welding manner.Be usually used in the bottom welding of pressure vessel with the mode that TIG weldering is filled with silk, the reason is that the air-tightness of TIG weld compared with
The stomata of weld seam when can reduce pressure vessel weldering welding well.The heat source of TIG weldering is direct-current arc, and operating voltage is 10~95 volts,
But electric current is up to 600 peaces.The correct mode of connection of welding machine is the anode of workpiece connection power supply, and the tungsten electrode in welding torch is as cathode.
Inert gas is generally argon gas.Profile is equipped with the bolt hole fixed with upper and lower box, also is provided with the spiral shell fixed with mould group
Keyhole, since profile wall thickness is relatively thin, all bolts hole are all made of staking hexagonal staking grommet nut, to guarantee that bolt torsion reaches
It is required that.
The upper box 1 of battery pack of the present invention, lower box 4 and 2 specific gravity of aluminum alloy frame assembly are low, and intensity is good, are guaranteeing
In the case where various aspects intensity requirement, the weight of battery pack is effectively alleviated, improves the specific energy of battery system.
