The invention discloses a structure for preventing a rear door from sinking during side collision, and belongs to the field of automobile doors.The structure is provided with: a side door rotationally connected with the side coaming; a doorsill which is fixedly connected to the lower part of the side coaming and is in contact with the side door; and a coupling part whcih comprises an embedded body fixedly connected to the side door and a coupling body fixedly connected to the doorsill, wherein the embedded body and the coupling body are connected in an embedded mode, the embedded body and the coupling body are clamped under the action of external force on the side door so that the side door and the threshold can be connected into a whole, and through the embedded body and the coupling body, when side collision occurs, the side door and the threshold can be connected into a whole to synchronously absorb energy; the side door is forcibly prevented from invading inwards, harm to the human body caused by large invasion of the side door is avoided, the overall safety coefficient of the vehicle is improved, and the effects of simple structure, high practicability and low cost are achieved.

    本发明公开了一种防止侧碰时后门内陷结构,属于汽车车门领域,本发明设置有与侧围板旋转连接的侧门;固连在所述侧围板下部与所述侧门接触的门槛;以及耦合部件,其包括固连在所述侧门上的嵌入体和固连在所述门槛上的耦合体;所述嵌入体与所述耦合体以嵌入的形式连接,其中,所述侧门在受外力作用下,所述嵌入体与所述耦合体卡合,以便使所述侧门和所述门槛连接为一体,本发明通过嵌入体和耦合体,当发生侧碰时能够使侧门和门槛连接为一体同步吸收能量,强制制止侧门内侵,避免由于侧门侵入较大引起对人体的伤害,提高车辆整体安全系数,具有结构简单,实用性强,成本低的效果。
