Description
Technical field
The utility model belongs to electric motor coach field, is used to arranging or installing power battery more specifically to one kind
Truss-like chassis and electric motor coach.
Background technology
With becoming increasingly conspicuous for energy problem and environmental problem, the development of pure electric automobile has obtained extensive concern and big
Power develops.
Existing tradition chassis is frame-type longitudinal beam structure, make the arrangement of pure electric coach power battery or installation be subject to it is very big
Limitation, battery can be only installed between two longerons or outside two longerons.
The content of the invention
To overcome defect existing in the prior art, the utility model provides a kind of purlin for being used to arranging or installing power battery
Posture chassis and electric motor coach.
Technical solution is used by the utility model solves its technical problem：
A kind of truss-like chassis for being used to arranging or installing power battery is designed, using three stage structure, front and rear sections are
Groove profile crossbeam, the leading portion groove profile crossbeam, back segment groove profile crossbeam middle part are welded into stage casing truss structure with connecting plate and section bar,
The stage casing truss structure is used to arranging or installing power battery, it is characterised in that the stage casing truss structure using through,
It is formed two layers up and down, and lateral cross section is the rectangle of closing, and plane is interior to use triangular structure, and it is identical to form three sizes
Power battery babinet.
In such scheme, leading portion groove profile crossbeam is the straight longitudinal beam structure of variable cross-section, back segment groove profile crossbeam is curved longitudinal beam structure.
In such scheme, a power battery babinet and two other power electric in three power battery babinets
Pond babinet is mutually perpendicular to.
The utility model also provides a kind of electric motor coach, it includes above-mentioned a kind of being used to arranging or installing power battery
Truss-like chassis.
Implement that the utility model is a kind of to be used to arranging or installing truss-like chassis and the electric motor coach of power battery, have with
Lower beneficial effect：
The utility model reduces vehicle dead weight, and reduces recondition expense, ensure that the quality and performance of vehicle.
Brief description of the drawings
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing：
Fig. 1 is a kind of schematic elevation view on the truss-like chassis for being used to arrange or install power battery of the utility model；
Fig. 2 is a kind of schematic top plan view on the truss-like chassis for being used to arrange or install power battery of the utility model；
Fig. 3 is the sectional view of stage casing truss structure.
In figure：Leading portion groove profile crossbeam 1, stage casing truss structure 2, back segment groove profile crossbeam 3, power battery babinet 4.
Embodiment
For a clearer understanding of the technical features, objectives and effects of the utility model, it is detailed now to compare attached drawing
Illustrate specific embodiment of the present utility model.
As shown in Figs. 1-2, the utility model provides a kind of truss-like chassis and electricity for being used to arranging or installing power battery
Dynamic car, using three stage structure, front and rear sections are groove profile crossbeam, and leading portion groove profile crossbeam 1,3 middle part of back segment groove profile crossbeam connect
Fishplate bar and template are welded into stage casing truss structure 2.In the present embodiment, the identical company of three sections of lap-joint's welding materials before, during and after
Fishplate bar, the thickness of connecting plate are not more than the thickness of stage casing truss structure 2, to improve the bending resistance stiffness of vehicle frame, bear bigger
Load.Stage casing truss structure 2 is used to arranging or installing power battery, and stage casing truss structure 2 is using through, its formation two up and down
Layer, lateral cross section are the rectangle of closing, and plane is interior to use triangular structure, forms three identical power battery boxes of size
Body 4.Each pad of stage casing truss structure 2 has connecting plate connection so that stress is revealed more, forming face contact, distribution of force
Equilibrium, being longitudinally spaced-apart for stage casing truss structure 2 are connected by vertical beam.
Preferably, a power battery babinet 4 is mutually perpendicular to two other power battery babinet 4 so that three power
4 connection and reasonable arrangement of Battery case, counterweight is uniform, and hauls out maintenance easy to battery.
Preferably, leading portion groove profile crossbeam 1 be the straight longitudinal beam structure of variable cross-section, back segment groove profile crossbeam 3 be curved longitudinal beam structure.
The present invention also provides a kind of electric motor coach, it includes a kind of above-mentioned truss for being used to arranging or installing power battery
Formula chassis.
The embodiment of the utility model is described above in conjunction with attached drawing, but the utility model is not limited to
The embodiment stated, above-mentioned embodiment is only schematical, rather than restricted, this area it is common
Technical staff is not departing from the utility model aims and scope of the claimed protection situation under the enlightenment of the utility model
Under, many forms can be also made, these are belonged within the protection of the utility model.
