When the plug-in hybrid electric vehicle is powered on, the engine does not work, and the carbon canister cannot be desorbed. To prevent fuel vapors from entering the canister and saturating the canister, the fuel vapors are typically sealed within the fuel tank, which therefore needs to withstand a certain pressure. The common method for improving the pressure resistance of the oil tank at present comprises the following steps: 1. a support frame is arranged in the oil tank and connected with the upper inner surface and the lower inner surface of the oil tank. The method needs a built-in mechanism of the assembly to place the support frame inside the oil tank during production, the support frame and tooling equipment have low cost, occupy the internal space of the oil tank, the support frame may occupy the positions of other parts, and some places such as inclined planes and the like are not suitable for placing the support frame. 2. The upper surface and the lower surface of the inner wall of the oil tank are connected in a butt joint mode (kiss-off). This approach can sacrifice significant tank volume and the small area is not suitable for kiss-off placement. 3. A plurality of transverse and longitudinal metal straps are arranged on the surface of the oil tank to form a cage-like structure. The metal cage in the method has high development cost and heavy weight, and does not accord with the development trend of light weight at present. 4. And connecting a reinforcing layer on the surface of the oil tank. The enhancement layer occupies less space and has light weight. The resin in the reinforcement layer must be a material compatible with the tank material.
