The invention discloses an automobile B-pillar upper connecting structure which comprises an automobile body covering part, a B-pillar inner plate and a B-pillar upper connecting part, the automobile body covering part and the B-pillar inner plate are connected in an attached mode, and the middle portion of the automobile body covering part and the middle portion of the B-pillar inner plate are sunken in the direction away from each other and form a reinforcing cavity; a B-column reinforcing plate and a B-column upper hinge reinforcing plate are arranged in the reinforcing cavity, the two ends of the B-column reinforcing plate are connected between the joints of the automobile body covering part and the B-column inner plate, and the B-column reinforcing plate is sunken towards the direction of the automobile body covering part. The B column upper hinge reinforcing plate is arranged in the groove of the B column reinforcing plate; the B-pillar upper connecting part is arranged between the B-pillar inner plate and the B-pillar reinforcing plate, and the two ends of the B-pillar upper connecting part are connected between the joints of the B-pillar inner plate and the B-pillar reinforcing plate. The structure stability and strength of the B-pillar upper part can be effectively improved, the Y-direction crushing force of the section of the B-pillar is greatly increased, and the bending resistance and deformation resistance of the B-pillar upper part of the automobile body are improved.
本发明公开了一种汽车B柱上部连接结构,包括车身覆盖件、B柱内板以及B柱上部连接件,车身覆盖件和B柱内板相互贴合连接,且两者的中间部位朝向远离对方的方向凹陷并形成加强空腔;加强空腔内设有B柱加强板和B柱上铰链加强板,B柱加强板的两端连接在车身覆盖件和B柱内板的连接处之间,且B柱加强板朝向车身覆盖件的方向凹陷;B柱上铰链加强板设置在B柱加强板的凹槽内;B柱上部连接件设置在B柱内板和B柱加强板之间,且其两端连接在B柱内板和B柱加强板的连接处之间。本发明可有效提高B柱上部结构稳定性及强度,极大增加B柱截面Y向压溃力,提高车身B柱上部的抗弯折、变形能力。
