Therefore, a better connection structure between the lower section of the B-pillar and the lower body can not only improve the performance of the vehicle, but also improve the ride comfort of the vehicle.
目前，大都数白车身结构为全钢制车身，传统的钢制车身中，门槛分为内门槛和外门槛，B柱处上车体与下车体的连接方式通常采用B柱直接伸进内门槛与外门槛之间，然后通过钢点焊接在一起，但是普遍存在侧面碰撞的安全性能较低，无法满足2018版碰撞法规的要求。At present, most body-in-white structures are all-steel bodies. In traditional steel bodies, the threshold is divided into inner threshold and outer threshold. The door sill and the outer door sill are then welded together through steel points, but the safety performance of side collisions is generally low, and it cannot meet the requirements of the 2018 version of the collision regulations.

For example, the lower section 100 of the B-pillar inner panel and the upper section 500 of the B-pillar inner panel can be welded as one by steel spot welding.
上述B柱处上车体与下车体之间的连接结构10至少具有以下优点：The connecting structure 10 between the upper vehicle body and the lower vehicle body at the B-pillar has at least the following advantages:
装配时，先将B柱内板下段100通过旋转攻丝铆接与自冲铆接相组合的方式装配于门槛200上，B柱内板下段100与门槛200共同形成门槛总成。B柱内板具有一安装区110，安装区110高于门槛200。再将横梁支架400的一端通过旋转攻丝铆接与自冲铆接相组合的方式装配于座椅横梁300上，横梁支架400与座椅横梁300形成座椅横梁总成。然后将座椅横梁300的一端安装于门槛200上，横梁支架400的另一端相对于横梁支架400的一端弯折后形成搭接板410，搭接板410叠置搭接于B柱内板下段100上的安装区110，最后将座椅横梁总成与门槛总成装配好后，再通过B柱内板下段100装配于B柱内板上段500。因此，座椅横梁300的受力点传至横梁支架400的搭接板410上，使得座椅横梁300的受力点提高，能够有效提高侧面碰撞的安全性能，更好的满足2018版碰撞法规的要求，并能够起到缓冲作用。During assembly, the lower section of the B-pillar inner panel 100 is first assembled on the threshold 200 through a combination of rotary tapping riveting and self-piercing riveting, and the lower section of the B-pillar inner panel 100 and the threshold 200 together form a threshold assembly. The B-pillar inner panel has a mounting area 110 that is higher than the door sill 200 . Then one end of the beam bracket 400 is assembled on the seat beam 300 through a combination of rotary tapping riveting and self-piercing riveting, and the beam bracket 400 and the seat beam 300 form a seat beam assembly. Then one end of the seat beam 300 is installed on the door sill 200, and the other end of the beam bracket 400 is bent relative to one end of the beam bracket 400 to form an overlapping plate 410, which is stacked and overlapped on the lower section of the inner panel of the B-pillar In the installation area 110 on the 100, after the seat beam assembly and the door sill assembly are assembled at last, the lower section of the B-pillar inner panel 100 is assembled on the upper section of the B-pillar inner panel 500. Therefore, the force point of the seat beam 300 is transmitted to the lap plate 410 of the beam bracket 400, so that the force point of the seat beam 300 is increased, which can effectively improve the safety performance of the side collision and better meet the 2018 version of the collision regulations. requirements and can act as a buffer.
本实用新型还提供一种汽车，包括车身，车身包括上述的B柱处上车体与下车体之间的连接结构10。因此，也具备有效提高侧面碰撞的安全性能，以满足2018版碰撞法规的要求，并能够起到缓冲作用的优点。The utility model also provides an automobile, including a body, and the body includes the connection structure 10 between the upper body and the lower body at the B-pillar. Therefore, it also has the advantages of effectively improving the safety performance of side collisions, meeting the requirements of the 2018 version of collision regulations, and being able to play a buffering role.
