Specific embodiment
Referring to attached drawing.
Scheme one: battery system ontology (1), by traditional structures such as battery modules, fixed module frame, cabinet, case lids, under
Cabinet tank wall foundation in place is slotted through crossbeam (3) shape, is penetrated through tank wall through crossbeam (3), is penetrated through at connection gap
It is welded and fixed and does water-proofing treatment.Upper beam (2) chassis runner physical connection, and in suitable position welded nut, bolt is installed
Perforation runs through crossbeam (3), chassis member, is fastened on upper beam (2).Lower box is penetrated through through crossbeam (3), is fallen with bottom
" several " type bracket (4) links into an integrated entity, and is built into the support base of lower layer's mould group, while being the branch of upper layer mould group again through crossbeam
Support group seat, then it is used as the structural member on chassis again through crossbeam simultaneously, connection left and right sides stringer plays similar original chassis crossrail
Structure function." several " type bracket (4) is fallen in zigzag shape in bottom, and bracket is connected as by two-end structure with through crossbeam (3)
One, and bracket is also connected as one with lower box, three is built into the pedestal for undertaking lower layer's mould group weight jointly.External electric appliance
Cartridge (5), the external electric appliance cartridge are independent assembly unit, are individually placed at except cabinet.Electrical appliance kit and cabinet connect
Socket part point is to be welded as a whole, and electrical appliance kit and lower box are penetrated through in suitable position aperture, so that high-low pressure harness passes through.
Fig. 1 is entire battery system structure figure, and Fig. 2 is Special vehicle chassis cell integral framework main view sectional view.From figure
In as can be seen that the crossbeam on traditional chassis is taken away, increase newly upper beam (2), chassis battery constituted together through crossbeam (3) it is new
Beam structure, play the function (holding left and right sides stringer) as former traditional crossbeam.It is in this structure it is noted that new
Increase the component that upper beam (2) are not power battery packs, and it is also the structure of power battery pack that chassis battery, which runs through crossbeam (5) simultaneously,
Component equally plays the beam effect of power battery pack.Through crossbeam (5) in battery pack structure, by longitudinal aspect up and down
Power plays the role of entrusting battery modules, and battery bottom bracket (4), lower box (7) weld together with through crossbeam (3), rise
To the structure function for entrusting lower layer's mould group, and the weight of upper layer mould group then has and undertakes through crossbeam (3).In chassis structure, pass through
Power of the crossbeam by left and right lateral aspects is worn, is connected together by installation bolt (10) with vehicle frame (8), it is vertical to play pulling two sides
Beam action.
Fig. 3 is the side view of structure, shows that the crossbeam of change can be one, be also possible to more, can be according to battery system
The overall dimensions of system, weight determine.It is by bolt or rivet shape that side view, which shows upper beam (2) and chassis runner (8),
Formula is fixed.Upper beam (2) both plays the left and right for holding two sides crossbeam, and the type face for depending on side rail inner also acts as reinforcement stringer
Effect.
Fig. 4 is the structure chart of lower box, it can be seen from the figure that run through the correspondence appropriate location of crossbeam (3) in perforation, under
The corresponding fluting (12) of cabinet (7), has allowed and has penetrated through through crossbeam (3).A few font brackets (4) in bottom with run through crossbeam (3), lower box
(7) weld together, the reinforcing rib of box house constitutes firm lower box structure in addition.It is secondary in tank wall to have splash guard
(13) it is welded at the connection gap of crossbeam and tank wall.
Fig. 5, Fig. 6 are local structure views, show that external electrical appliance kit (5) and Battery case ontology (1) are relatively independent
Two components, wherein burst at the seams on lower box and corresponding electrical appliance kit shell beam hole (14), so that high-low pressure harness passes through, electric appliance
Box (5) is welded on battery case ontology (1), is fully welded at the docking of harness hole, to guarantee the leakproofness of battery case ontology.Two width figures are also
Show that independent electrical appliance kit can be placed on cabinet one end, body side can also be placed on.
Scheme two: it as shown in Figure 7,8, is connect, is transferred by switching support (15) with automobile longitudinal girder (8) through crossbeam (3)
Bracket (15) is fixed by bolt or rivet and stringer (8), passes through longitudinal bolt through crossbeam (3) incidental battery pack structure
And lateral bolt or pin and switching support (15) is fixed.Remaining arrangement is consistent with scheme one.
