The invention relates to an automobile seat transmission device which comprises a bearing mechanism, a sliding rail and a main lead screw, the main lead screw is connected into the sliding rail and is parallel to the sliding rail, the bearing mechanism is slidably connected with the sliding rail and the main lead screw, a planetary transmission mechanism is rotationally connected into the bearing mechanism, and the planetary transmission mechanism comprises a first transmission disc and a plurality of transmission shafts. The first transmission disc is rotationally connected with the inner wall of the planetary transmission mechanism, the first transmission disc and the main lead screw coaxially rotate, the multiple transmission shafts are distributed in a circumferential array mode and rotationally connected with the first transmission disc, external threads are arranged in the circumferential direction of the main lead screw, and the multiple transmission shafts are meshed with the circumferential direction of the main lead screw; the multiple transmission shafts rotate while rotating relative to the center shaft of the main lead screw and are used for driving the bearing mechanism and the sliding rail to slide. Load and friction force between the seat and the main lead screw are shared, the risk of friction damage or failure is reduced, the situation of fracture or plastic deformation in the operation process is reduced, and it is guaranteed that the seat can normally and stably operate.
本申请涉及一种汽车座椅传动装置,其包括承载机构、滑轨和主丝杆,主丝杆连接于滑轨内并与滑轨平行设置,承载机构分别滑移连接滑轨和主丝杆,承载机构内转动连接有行星传动机构,行星传动机构包括第一传动盘和若干传动轴,第一传动盘与行星传动机构的内壁转动连接,第一传动盘与主丝杆同轴转动,若干传动轴呈圆周阵列分布与第一传动盘转动连接,主丝杆的周向设有外螺纹,若干传动轴与主丝杆的周向啮合,若干传动轴相对主丝杆的中心轴公转的同时自转,用于带动承载机构与滑轨滑移。本申请分担与主丝杆之间的负载和摩擦力,降低摩擦损坏或者失效的风险,减小运转的过程中发现断裂或塑性变形的情况产生,保障座椅能够正常稳定地运行。
