Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 2 and 3, in the present embodiment, a lightweight B-pillar reinforcement assembly includes a B-pillar reinforcement 1 and a B-pillar inner panel 2. The B column reinforcement 1 is integrally I-shaped and is formed by integral punch forming.

As shown in fig. 2 to 5, the B-pillar inner panel 2 is a split type, and includes one or more first brackets 3, one or more second brackets 4, and one or more third brackets 5; each first bracket 3, each second bracket 4 and each third bracket 5 are respectively welded on the B-pillar reinforcement 1; each first bracket 3, each second bracket 4 and each third bracket 5 are provided with a fixing hole 6 (such as a nut hole or a clip hole) for providing a mounting point for a B-pillar trim panel, a front safety belt and a retractor. In this embodiment, there are two first brackets 3, four second brackets 4, and two third brackets 5.

As shown in fig. 4 and 5, in the present embodiment, the first bracket 3 is shaped like a "ji", the second bracket 4 is shaped like an "M", and the third bracket 5 is shaped like an "L".

As shown in fig. 4 and 5, in the present embodiment, the middle portions of the first bracket 3 and the second bracket 4 are mounting structures, and the fixing hole 6 is formed in the mounting structures;

as shown in fig. 3, in this embodiment, welding flanges 7 are disposed on two sides of the first bracket 3 and the second bracket 4, and are welded to the B-pillar reinforcement 1 through the welding flanges 7.

As shown in fig. 4, in this embodiment, one side of the third bracket 5 is a mounting structure, and the fixing hole 6 is formed in the mounting structure; and the other side of the third bracket 5 is a welding flange 7, and is welded with the B-pillar reinforcement 1 through the welding flange 7.
