Fixed beam, battery tray, posterior bracket are aluminum alloy behind said girder, vehicle frame front portion, the preceding fixed beam of battery tray, the battery tray.
Said girder is logical to be passed through before and after the vehicle frame.
Be located at before the battery tray at said girder middle part fixed beam and girder formation " well " font truss structure behind the fixed beam and battery tray.
It is anterior to be positioned at the anterior vehicle frame of said girder, is positioned at girder middle part, the battery tray forward and backward fixed beam vertical with girder, and is positioned at girder rear portion, the posterior bracket vertical with girder, with two girders constitute two indulge three horizontal strokes structure.
The said girder front end leaf spring type front overhang of can arranging in pairs or groups.
The said girder front end MacPherson type front overhang of can arranging in pairs or groups.
Have additional floor holder and side between vehicle frame front portion and the battery tray and strengthen longeron.
The beneficial effect of the utility model is:
1. because the utility model has used the main material of aluminum alloy as vehicle frame, small-sized non-highway with this low speed driving of battery-driven car in nearly can reduce the deadweight of 60% vehicle frame on the special machine motor-car, the continual mileage of vehicle is improved.
2. adopted logical main beam structure design of passing through front and back; Front portion can freely arrange in pairs or groups leaf spring and MacPherson type front overhang; Improved must the arrange in pairs or groups body frame structure for automotive of independent front overhang of general-duty in the present design, stability, traveling comfort and the safety of car load are greatly improved.
3. the installation site with storage battery moves forward as far as possible; And make storage battery be the arrangement of " one " font; Make the center reach 2-4cm of car load; The problem of the ubiquitous center of gravity of battery-driven car of improving this type after too partially, and can make the left and right sides angle of overturn increase 6-8 °, the mode that " one " font is arranged can also improve the stability of car load.
4. the structure of two vertical three horizontal strokes is greatly improved the integral structure of vehicle frame, and " well " font truss structure has guaranteed the intensity of vehicle frame.
