Abstract
The invention discloses a battery frame of an electric automobile. The battery frame is used for arranging a power battery pack of an electric automobile, and comprises a frame body with an upward opening, wherein the frame body comprises a rectangular bottom plate and side plates around the bottom plate; the bottom plate and each side plate are molded integrally; each side plate constructs the frame body together with the bottom plate by bending towards the same direction; adjacent side plates are connected hermetically; and frame sections for reinforcing the frame body are arranged on the edge of and inside the frame body. Due to the adoption of a peripheral reinforcing process for the frame body and the frame sections which are molded in a bending way, a processing technic is simple, welding workload is reduced, the welding standard requirement is lowered, the pressure resistance and hermetic tensile strength are enhanced, processing cost is reduced, and size accuracy is ensured.

Technical field
The invention belongs to vehicular propulsion field, relate in particular to a kind of battery of electric vehicle frame.
Background technology
Along with the development of industrial technology, petroleum resources as power source reduce day by day because it is non-renewable, simultaneously for alleviating environmental pollution, the exhaust emissions of fuel combustion vehicle is also further strictly controlled, for these reasons, green novel energy source becomes the hot topic of exploitation, and motor vehicle also becomes the direction of current auto industry research and the emphasis of exploitation.As the battery of electric powered motor core, it need to be arranged on has in the good battery frame of space compactness, resistance to pressure and sealing, as depicted in figs. 1 and 2, battery of electric vehicle frame adopts each 3 of both sides, 11 and 8 side plate 12(front and back of 1 base plate, each side 1 at present) splice with welding manner with stiffening profile 13.There is following defect in this kind of structure: one, weld time long, to personnel weld technical ability require high; Two, cross weld easily produces pore and crack defect; Three, weld seam is too much overstocked, and between weld seam, internal stress causes bead crack defect and box house hole is biased moves, and welded seal requires high, and welding cost is high.
Summary of the invention
In view of the defect of above-mentioned prior art existence, the object of the invention is to propose a kind of employing aluminium alloy is raw material, by aluminum alloy plate materials bending technique and aluminium alloy extrusions strengthening process, obtain profile and good resistance to pressure, the battery of electric vehicle frame of sealing, be applicable to city energy-saving electric vehicle.
Object of the present invention will be achieved by the following technical programs:
A kind of battery of electric vehicle frame, for the power battery pack that electric automobile is installed, comprise the shaped as frame body of an opening upwards, described shaped as frame body comprises the base plate of rectangle and the side plate of described base plate surrounding, between described base plate and each side plate, be integrated, each side plate, by forming described shaped as frame body towards bending in the same way with described base plate, is tightly connected between adjacent described side plate.
Preferably, above-mentioned battery of electric vehicle frame, wherein: the edge of described shaped as frame body and inside are provided with the frame section bar for reinforcing described shaped as frame body.
Preferably, above-mentioned battery of electric vehicle frame, wherein: the side plate of the described base plate left and right sides is convex shape side plate, the top of described convex shape side plate is connected with described base plate, the side plate of the upper and lower both sides of described base plate is rectangular side panels, described rectangular side panels, along the edge fold of described convex shape side plate, forms the groove at upper and lower two ends, in described groove, is provided with frame section bar.
Preferably, above-mentioned battery of electric vehicle frame, wherein: between adjacent described side plate, connect by welded seal.
Preferably, above-mentioned battery of electric vehicle frame, wherein: described shaped as frame body is aluminium alloy shaped as frame body, and described frame section bar is aluminum alloy frame frame section.
Outstanding effect of the present invention is: the present invention adopts shaped as frame body and the frame section bar periphery strengthening process of wrap direction moulding, and processing technology is simple, reduces welding job amount, reduce welding standard requirement, strengthen resistance to pressure sealing hot strength, cut down finished cost, guarantee accuracy to size.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, so that technical solution of the present invention is easier to understand, grasp.
