The invention discloses a lifting mechanism with the buffering function. The lifting mechanism comprises a rack, a lifting platform and a driving assembly, and the lifting platform comprises a platform body and a plurality of connecting bases arranged on the platform body; the driving assembly comprises a plurality of screw rods, a plurality of nuts and a driving module, the screw rods are rotatably arranged on the rack in the axial direction of the screw rods, the screw rods are sleeved with the nuts, the driving module is used for driving the multiple screw rods to rotate synchronously, the multiple screw rods are sleeved with the multiple connecting bases in a one-to-one correspondence mode, the multiple connecting bases are located above the nuts, and the lifting mechanism further comprises a plurality of deformable buffering parts; and the two ends of the buffering parts abut against the end faces, close to one another, of the nuts and the connecting bases. Through cooperation of the connecting bases, the buffering parts and the nuts, when the lifting platform inclines due to gravity center shift of a bearing component, the connecting bases move in the direction close to the nuts, the buffering parts can offset part of downward pressure of the connecting bases through deformation force of the buffering parts, balance buffering of the connecting bases is achieved, and the inclination trend of the lifting platform is slowed down.

    本发明公开了一种具有缓冲功能的升降机构,包括机架、升降平台和驱动组件,升降平台包括平台本体、设于平台本体上的多个连接座,驱动组件包括多根分别绕其自身轴向可转动的设于机架上的螺杆、多个套设于螺杆上的螺母、用于驱动多根螺杆同步转动的驱动模块,多个连接座分别一一对应的套设于多根螺杆上且位于螺母上方,升降机构还包括多个可形变的缓冲部,缓冲部两端分别与螺母和连接座相互靠近的一端面相抵接。本发明通过连接座、缓冲部和螺母的配合,在升降平台因承载的构件重心偏移而产生倾斜时,连接座向着靠近螺母的方向移动,缓冲部能够利用其自身的形变力抵消连接座的部分下压力,实现对连接座的平衡缓冲,减缓了升降平台的倾斜趋势。
