The invention discloses a connecting piece, a connecting method, a lower vehicle body structure of a vehicle and a vehicle wheelbase adjusting method. The connecting piece comprises a bottom plate and a connecting structure arranged on the surface of the bottom plate, the bottom plate is of a central symmetry structure and is used for being fixedly connected with a first component. The connecting structure is used for being fixedly connected with a second component; if the connecting structure is rotated by 180 degrees around the first shaft, the position state of the connecting structure after rotation can be coincided with the position state before rotation after translation in the first direction; the first shaft passes through the symmetry center of the bottom plate and is perpendicular to the plate face of the bottom plate, and the first direction is parallel to the plate face of the bottom plate. By rotating the connecting piece around the first shaft, the position state of the bottom plate is not changed before and after rotation, only the position of the connecting structure is translated before and after rotation, and other positions are not changed; therefore, under the condition that the structures of the first component, the second component and the adapter are not changed, two integral structures are formed after final connection.

    本发明公开了一种连接件、连接方法、车辆下车体结构及车辆轴距调整方法。该连接件包括底板和设置在所述底板板面上的连接结构;所述底板为中心对称结构,用于与第一部件固定连接;所述连接结构用于与第二部件固定连接;若将所述连接结构绕第一轴旋转180°,则所述连接结构旋转后的位置状态沿第一方向平移能够与旋转前的位置状态重合;第一轴过所述底板对称中心且垂直所述底板板面,第一方向平行所述底板板面。通过绕第一轴旋转该连接件,底板旋转前后位置状态不变,而连接结构在旋转前后仅位置做了平移变动,其他保持不变;从而使得在第一部件、第二部件和转接件结构均不变的情况下,最终连接后具有两种整体结构。
