Description

Technical Field

[0001] This utility model relates to a fuel tank, specifically an integrated anti-surge plate for a high-pressure fuel tank. Background Technology

[0002] With the implementation of the China VI emission standard (Phase b), the control requirements for fuel evaporation emissions have significantly increased. Traditional gasoline vehicles rely on carbon canisters to adsorb vapors, but the capacity of carbon canisters is limited. High-pressure fuel tanks, through structural reinforcement and intelligent valve linkage such as the FTIV isolation valve, achieve dynamic vapor sealing and directional emission, overcoming the bottleneck of adapting atmospheric pressure fuel tanks to hybrid vehicles. In existing high-pressure fuel tank structures, various components such as baffles, liquid collectors, and various exhaust valves and pipelines are built-in. These components are directly blow-molded and connected to the inner wall of the tank during the fuel tank blow molding process. During the blow molding operation, each component needs to be installed individually, affecting the blow molding time and efficiency. The long installation time of multiple components can easily affect the temperature of the blow-molded material and subsequent molding. At the same time, connecting multiple components to the inner wall of the high-pressure fuel tank has a significant impact on the overall thickness of the tank and the thickness and strength of the connection parts, which is not conducive to the stability of the blow molding quality of the high-pressure fuel tank. Summary of the Invention

[0003] This utility model provides an integrated anti-surge plate for high-pressure oil tanks that is compact, stable, easy to assemble and blow mold, and also takes into account the blow molding quality.

[0004] The technical solution adopted by this utility model is: an integrated anti-surge baffle for a high-pressure oil tank, including an integral anti-surge baffle frame, on which two or more support columns are vertically arranged, and the upper and lower end faces of the support columns are integrally blow-molded connected to the inner wall of the high-pressure oil tank. The feature is that: one or more GVV gravity valves and liquid collectors are fixedly connected to the integral anti-surge baffle frame, the GVV gravity valve is connected to the liquid collector through an exhaust pipe, the liquid collector is connected to an FLVV refueling and exhaust valve, and the liquid collector is also connected to an exhaust connector fixedly connected to the integral anti-surge baffle frame and connected to a ventilation pipe outside the high-pressure oil tank through a vent pipe.

[0005] Furthermore, the GVV gravity valve and liquid collector are not fixedly connected to the inner wall of the high-pressure oil tank.

[0006] Furthermore, two or more GVV gravity valves are respectively located on both sides of the integral wave deflector frame.

[0007] Furthermore, the liquid collector is located in the middle of the integrated wave shield frame.

[0008] Furthermore, the exhaust pipe and vent pipe are fixed by clips installed on the integral wave deflector frame.

[0009] Furthermore, the two or more GVV gravity valves are installed at different heights on the integrated wave deflector frame.

[0010] Furthermore, the GVV gravity valve is snapped onto the snap-fit ​​bracket, which is then snapped onto the snap-fit ​​head bracket connected to the integral wave deflector frame.

[0011] Furthermore, the liquid collector is provided with two or more snap-fit ​​ears on its outer side, which snap-fit ​​ears are connected to the snap-fit ​​head frame on the integral anti-surge plate frame.

[0012] Furthermore, the exhaust connector is a female or male connector that is inserted directly into the ventilation pipe.

[0013] Furthermore, the inner cross-sectional shape of the support column is fitted to the side of the integral wave deflector frame, and the outer side of the support column is connected to the side of the integral wave deflector frame by a clamp or a clamp head through a clamp or a clamping plate that is axially aligned with the support column and has a cross-sectional shape that matches the support column.

[0014] The beneficial effects of this utility model are:

[0015] 1. An integrated anti-surge plate frame is used to install the liquid collector, GVV gravity valve and various pipes, which facilitates quick installation during blow molding operations, improves blow molding efficiency, and ensures blow molding quality.

[0016] 2. The integrated wave shield frame is connected between the upper and lower inner walls of the high-pressure oil tank by two or more support columns. While taking into account wave protection and noise reduction, it provides more stable support for the high-pressure oil tank, which is conducive to improving the service strength of the high-pressure oil tank.

[0017] 3. Two or more GVV gravity valves are installed on both sides of the integrated baffle frame at different heights, which can better regulate the overall fuel supply and ensure the sealing and safety of the fuel system under the fuel tank under various vehicle conditions; and send the vapor into the collector, and return the fuel to the fuel tank through the FLVV refueling and venting valves and release it outward through the vent pipe, exhaust connector and ventilation pipe to ensure safe and stable pressure regulation of the high-pressure fuel tank.
