The shaft support is provided with a shaft hole and comprises a main body and elastic clamping protrusions, the elastic clamping protrusions are connected to the left side and the right side of the main body, the elastic clamping protrusion on the left side protrudes leftwards and protrudes out of the left side surface of the main body, and the elastic clamping protrusion on the right side protrudes rightwards and protrudes out of the right side surface of the main body. The sliding rail assembly comprises an upper rail, a lead screw and a shaft support, and the lead screw is matched with the shaft hole, so that the lead screw is connected with the shaft support; matching holes are formed in the left side wall and the right side wall of the upper rail and matched with the elastic clamping protrusions on the left side and the right side of the shaft support correspondingly, and therefore the upper rail is connected with the shaft support. According to the sliding rail assembly, a shaft support riveting hole does not need to be formed in the upper wall of the upper rail, so that the position layout of a seat support and the like on the upper rail cannot be limited, the sliding rail assembly is more flexible and convenient to apply, obvious impact noise cannot be generated when the lead screw rotates at a high speed, and a preassembling process is not needed before the shaft support and the upper rail are connected.
本申请公开一种轴支座和滑轨总成,轴支座设有轴孔,轴支座包括主体和弹性卡凸,主体的左右两侧连有弹性卡凸,左侧的弹性卡凸向左凸起并凸出于主体的左侧表面,右侧的弹性卡凸向右凸起并凸出于主体的右侧表面,滑轨总成包括上轨道、丝杠和轴支座,丝杠伸与轴孔配合,以此实现丝杠与轴支座的连接;上轨道的左侧壁和右侧壁设有配合孔,分别与轴支座左右两侧的弹性卡凸配合,以此实现上轨道与轴支座的连接。本申请不用在上轨道的上壁开设轴支座铆孔,因此不会限制座椅支架等在上轨道上的位置布局,使滑轨总成应用起来更加灵活方便,且丝杠在高速转动时不会产生明显的撞击噪音,且在连接轴支座和上轨道前不需要预装工艺。
