The invention relates to an automobile part structure, in particular to an A-pillar lower joint structure. The A-pillar lower joint structure comprises an A-pillar inner plate, an A-pillar reinforcingplate, a side wall outer plate, an outer threshold, an inner threshold and an outer threshold sealing plate; the outer threshold sealing plate is provided with a lower connecting plate used for beingconnected with the outer threshold, a middle connecting plate used for being connected with the side wall outer plate and an upper connecting plate used for being connected with the A-pillar reinforcing plate; the lower end of the A-pillar reinforcing plate is connected to the outer threshold; and the side wall outer plate, the A-pillar reinforcing plate, the outer threshold sealing plate and theouter threshold integrally form a closed structure. Under the condition of no side wall outer plate wrapping, the sealing performance can be guaranteed, the rigidity and strength can be enhanced, thematerial utilization rate is increased, and the production difficulty can be reduced.

    本发明涉及一种汽车零部件结构,尤其是涉及一种A柱下接头结构。一种A柱下接头结构,包括A柱内板、A柱加强板、侧围外板、外门槛、内门槛和外门槛封板,所述的外门槛封板上设置有用于与外门槛连接的下连接板、用于与侧围外板连接的中连接板和用于与A柱加强板连接的上连接板,所述的A柱加强板的下端连接在外门槛上,侧围外板、A柱加强板、外门槛封板和外门槛整体形成一个封闭结构。本发明在无侧围外板包裹的情况下,能够保证密封性能,能够增强刚度和强度,提升材料利用率并且能够降低生产难度。
