The invention discloses a side wall reinforcing plate, a machining method of the side wall reinforcing plate, a side wall reinforcing plate assembly and a vehicle. The side wall reinforcing plate comprises an A column reinforcing plate and a B column reinforcing plate, the A column reinforcing plate and the B column reinforcing plate are connected through laser tailor welding to form an integrated half door ring structure, and the half door ring structure is provided with a downward opening. In the side wall reinforcing plate, the material sheets of the column A reinforcing plate and the column B reinforcing plate can be connected through laser tailor welding and then form an integrated half door ring structure through hot stamping, and then the half door ring structure can be connected with the doorsill reinforcing piece to form a closed door ring structure. Due to the arrangement of the side wall reinforcing plate, the overall weight is reduced, the tool cost is reduced, the production efficiency is improved, and the tolerance precision of a product is controlled.

    本申请公开了一种侧围加强板及其加工方法、侧围加强板总成和车辆。侧围加强板包括:A柱加强板和B柱加强板,所述A柱加强板和所述B柱加强板通过激光拼焊连接,以形成一体式的半门环结构,所述半门环结构具有朝下的开口。该侧围加强板中,其A柱加强板和B柱加强板的料片可通过激光拼焊连接后,再通过热冲压形成一体式的半门环结构,然后该半门环结构可与门槛加强件连接形成封闭的门环结构。该侧围加强板的设置,有利于实现整体的减重,工装成本的降低,生产效率的提高,且有利于产品公差精度的控制。
