Further, the framework is of a thin-wall structure and is provided with a plurality of concave cavities. The framework is provided with the concave cavity, and the foaming agent can be drilled into the concave cavity and filled in the concave cavity when being baked, so that the mechanical property and the stability of the framework are effectively improved.

Furthermore, a reinforcing rib is arranged in the concave cavity. The reinforcing ribs enhance the structural strength of the cavity to enhance the stability of the framework.

Further, the foaming agent is dispersed and injected on the periphery of the framework. The foaming agent is dispersedly arranged on the periphery of the framework, so that the foaming agent can fill cavities and gaps of the framework when being baked.

Furthermore, the framework is provided with at least two convex mounting parts, and the mounting parts are clamped into the threshold beam. The installation part is clamped in the doorsill beam, so that the framework and the doorsill beam are convenient to position.

Furthermore, the middle part of the framework is provided with a through hole structure. The through hole structure effectively reduces the weight of the framework, and foaming agents can be drilled into the framework to enhance the local mechanical property.

Further, the framework is made of nylon or glass fiber by injection molding.

Further, baking is performed during the electrophoresis process.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: the plastic part is used for manufacturing the framework, so that the weight of the reinforcing structure is reduced, in addition, the foaming agent is fixed on the framework in an injection molding mode, the foaming agent is light in weight, the framework and the threshold beam can be connected together by the foaming agent when the foaming agent is baked, the connecting workpieces or welding procedures are reduced, the quality of the reinforcing structure is effectively reduced, and the lightweight design concept is met.
