Background
With increasingly strict environmental regulations, the management requirements of automobile fuel systems for steam are more and more strict, and particularly for hybrid electric vehicles, in order to achieve the environmental protection indexes required by the regulations, the current technical scheme is to perform steam management on a plastic storage container, and the steam management under the conventional working conditions causes the positive pressure or negative pressure condition to be generated inside the fuel system, so that the plastic storage container with certain structural strength is required to ensure the normal operation of the fuel system in a large pressure range.
For the structural reinforcement of plastic storage containers, it is a common prior art to add internal reinforcing connecting members inside the plastic storage containers to connect the upper and lower surfaces of the plastic storage containers. The internal connection is capable of providing a pulling force when the pressure is elevated; when the pressure is reduced, the internal reinforcing connecting piece can provide support to prevent the plastic storage container from deforming to cause fuel leakage. There are three major drawbacks to the application of this technology: firstly, the arrangement of the internal reinforcing connecting piece in the plastic storage container is influenced by the positions of other parts such as a valve, a wave board and the like, and the design freedom degree is not high; meanwhile, due to structural limitation, the internal reinforcing connecting piece is only connected with the upper surface and the lower surface of the plastic storage container, so that the deformation control capability of the side surface of the plastic storage container or a complex curved surface which cannot be provided with the connecting piece due to limited space is weaker; in addition, since a built-in reinforcing connector needs to be placed inside the plastic storage container, a complicated manufacturing process is required, and manufacturing cost is increased.

In the technical scheme of this application, the surface of plastics storage container can be external surface also can be the internal surface.
Wherein the reinforcing part is made of a plate-type material or other materials with certain rigidity and is attached to the surface of the plastic storage container, and forms a physical connection structure with the wall of the plastic storage container through riveting or other similar connection methods.
In the technical scheme of the application, the plastic storage container achieves the improvement of rigidity through the reinforcing part, so that the normal work of a fuel system in a large pressure range (at least 0.13MPa or above) is ensured. The position of the reinforcing part can be set at any position on the surface of the plastic storage container wall or at any position inside the plastic storage container wall according to requirements, and is generally set at a position with a large deformation amount under a large pressure condition, or other positions where the reinforcing part is required to be set, and is not limited in the application.
In the technical solution of the present application, the reinforcing part is made of a high-strength material, and generally a high-strength metal, such as but not limited to aluminum, aluminum alloy, steel, etc., or a high-strength composite woven material, such as a high-strength plastic, etc., is selected, and the shape of the reinforcing part is any shape that fits the surface of the plastic storage container, and at least one through hole 21 is provided on the reinforcing part for connecting with the plastic storage container.
The reinforcing part forms a physical connection structure with the wall of the plastic storage container in a riveting mode, partial material of the wall of the plastic storage container is softened after being subjected to processing technologies such as heat and the like, and after the partial material penetrates through the through hole in the reinforcing part, a riveting structure larger than the through hole is formed on one side, away from the plastic storage container, of the reinforcing part, so that the reinforcing part is connected with the surface of the wall of the plastic storage container.
The plastic storage container can be additionally provided with a reinforcing part in an area where deformation of the plastic storage container is controlled at will, the reinforcing part can be a plate without a special shape or a plate with other shapes or a special-shaped structure, the reinforcing part is attached to the wall of the plastic storage container, and in order to ensure that the structural strength of the plastic storage container is enough, the minimum effective wall thickness of the reinforcing part is not less than 0.1 mm.

In order to achieve a better connection effect, the reinforcing parts can be subjected to heating pretreatment, and the pretreatment temperature is selected according to the materials of the reinforcing parts. After the material blank enters between the left die and the right die, the air pressure in the plastic storage container during hollow blow molding presses the material blank out of the through hole, and the riveting groove of the die is matched to form a physical connection structure. Compared with welding after molding, the method can simplify the process flow and improve the connection quality and the process stability.
