Abstract
The utility model relates to an in-connection smooth transition pre-stressed fuel tank which is the improvement on a fuel tank. The body of the utility model is shaped in a pre-stressed mode, and an outward two-dimensional arc shape is formed. An end cap is drawn into a three-dimensional arc shape in a pre-stressed mode, and the end cap and the body both adopt the arc outward pre-stressed in-connection structure and are welded into a whole. The in-connection smooth transition pre-stressed fuel tank manufactured according to the structure can solve problems of low strength and rigidity, easy damage, small capacity and inaesthetic shape of an out-connection fuel tank without pre-stressed structure.
Description
The utility model relates to the improvement to a kind of fuel tank of vehicle.
Usually the outer connection of usefulness does not have the fuel tank of prestressed structure, and intensity, rigidity are lower, fragile; All there are corner angle on the surface, has that anti-corrosion treatment is bad to be done, so edges and corners are perishable, capacity is relatively little, moulding is not attractive in appearance.
The purpose of this utility model is to be externally connected with corner angle and not have problems such as fuel tank intensity, the rigidity of prestressed structure is lower, fragile, perishable, capacity is relatively little, moulding is not attractive in appearance with connecting rounding off prestress fuel tank in a kind of, solving.
1 the utility model is achieved in that body 2 usefulness prestress mode moulding in conjunction with the accompanying drawings, forms outside two-dimentional arcuate shape; End cap 1 usefulness prestress mode is drawn into the three dimension arch shape, and end cap 1, body 2 all adopt to outer arcuate prestress interconnect structure, and integrally welded.
By the interior connection rounding off prestress fuel tank that said structure is made, owing to adopt to the outer arcuate prestressed structure, intensity, rigidity are strengthened, and is not fragile; Outside face slyness, no corner angle can solve the problems such as the corner angle fuel tank is perishable, capacity is relatively little, moulding is not attractive in appearance that are externally connected with.
Description of drawings;
Connect rounding off prestress fuel tank scheme drawing in Fig. 1
Embodiment: connect in slick and sly the prestress fuel tank with the sheet metal punching press, be shaped, be welded, application makes.
Claims (1)
1, a kind of interior rounding off prestress fuel tank that connects is characterized in that body (2) with the moulding of prestress mode, forms outside two-dimentional arcuate shape; End cap (1) draws into the three dimension arch shape with the prestress mode, and end cap (1), body (2) all adopt to outer arcuate prestress interconnect structure, and integrally welded.
