The invention has the beneficial effects as follows:
This programme is to be made parts by aluminium sheet punching press, aluminum square tube, aluminum square tube bending completely, the electric automobile frame that then welded frock is welded after fixing.
Compared with electric automobile steel vehicle frame, the advantage of the aluminum Vehicle Frame Design in the present invention is: vehicle frame light weight, adds car load course continuation mileage；Have employed two kinds of PROCESS FOR TREATMENT hot, cold, have significantly high intensity and corrosion resistance；Aluminium alloy extrusions plasticity is relatively strong, and parts make simple；Stable chemical performance, can be recycled；There is no metallic pollution, it does not have toxicity, more environmental protection.The electric automobile frame of aluminum alloy materials, reduces complete vehicle weight, increases electric automobile course continuation mileage.
Accompanying drawing explanation
Fig. 1 is the axonometric chart of the present invention.
In figure: 1 carrier frame, 11 front wheel assembly installing zones, 12 foot-operated districts, 13 battery component installing zones, 14 rear wheel suspension system installing zones, 15 crossbeams, 16 longerons, 17 pick up the ears, 18 floor stringers, 2 installing frames, 21 articulated sections, 31 first vertical beams, 32 assistant reinforcement gussets, 33 first frameworks, 34 aluminium alloy pressed sheets, 41 second vertical beams, 42 second frameworks, 43 aluminium alloy punching press accessory plates, 44 Aluminum alloy columns.
Detailed description of the invention
As it is shown in figure 1,
As the full welding aluminum alloy vehicle frame of one, this electric automobile frame is mainly made up of following feature.
Carrier frame 1, this carrier frame 1 is the crossbeam by aluminum alloy material and longeron is crisscross arranged and is welded to connect " song " font formed, bent font described herein is so as to outline is this shape, specifically, it is connected to some floor stringers 18 at described carrier frame internal welding, so improve the bulk strength of carrier frame, and the installation for other building blocks of functions provides space.In this structure, the section of crossbeam 15 and longeron 16 is the aluminum extrusion profile of day font, and floor stringer, for being also that aluminum square tube makes, forms a chassis.
By the difference of installation function parts, carrier frame is in turn divided into from front to back front wheel assembly installing zone 11, foot-operated district 12, battery component installing zone 13 and rear wheel suspension system installing zone 14, on the front end of described carrier frame, wherein it is provided with front wheel assembly installation picks up the ears 17, for installing front wheel assembly easily and fast.
And the postmedian in described carrier frame 1 is provided with the installing frame 2 being made up of U-shaped collar tie beam and the auxiliary rod of aluminum alloy material for installing battery component, described installing frame rear-side cross member is provided with the articulated section 21 for hinged installation seat, thus easily seat can be arranged on the top of battery component, and internal battery component has been protected.
