The invention provides a B column structure reinforcing part, and relates to the field of automobile reinforcing parts. The reinforcing part comprises a fixing framework, expansion mucilage glue adhered to the surface of the fixing framework and a fixing buckle, the overall overlook projection of the fixing framework is trapezoidal, a protruding adhesion part is arranged in the middle of the fixing framework, a connecting opening integrally formed with the fixing framework is formed in the side edge of the fixing framework, reinforcing rib plates are arranged on the two sides of the adhesion portion, the expansion mucilage glue is adhered to the surface of the adhesion portion, and the fixing buckle is connected with the connecting opening. According to the fixing framework, through the combined action of the reinforcing rib plates and the expansion mucilage glue, the side collision and top pressing performance of a vehicle body is improved, the weight of the vehicle body is reduced, the local metal plate structure of the vehicle body is simplified, and the reinforcing part has the advantages of being easy to manufacture, convenient to install and the like.
Description
technical field [0001] The invention relates to an automobile reinforcement, in particular to a B-pillar structure reinforcement. Background technique [0002] Structural reinforcements have been widely used in the automotive industry at present, with the characteristics of light structure and high specific strength, and have become another composite material tool for body design engineers to provide structural support or reduce noise / vibration. For example, in the body structure, reinforcements are mainly used in beams, columns, beams, key hinge points, door frames and other positions of the vehicle. Usually, the structural reinforcement is mainly composed of three parts, the nylon fiberglass skeleton, the epoxy resin structural expansion adhesive, and the buckle or welding sheet for pre-installation. The structural expansion adhesive material is usually in an unexpanded state when the reinforcement is manufactured. However, when activated, such as by heating, it expands a...
