A driving mechanism of an electric sliding rail for a vehicle seat comprises a pair of outer sliding rails, inner sliding rails are connected to the outer sliding rails, inner sliding rail sliding supporting frames and gap eliminating assemblies are arranged at the front ends and the rear ends of the inner sliding rails, and lead screws are arranged in inner cavities of the outer sliding rails; the device is characterized in that the driving mechanism is provided with a sliding frame plate, a driving motor and a gearbox, the sliding frame plate is vertically arranged on the upper surface of the inner sliding rail, and the driving motor is installed in the middle of the sliding frame plate; the gear box is transversely arranged in an inner cavity of the outer sliding rail and penetrates through the lead screw; a gear box fixing support is further installed on the gear box, the support is fixed to the inner sliding rail, a distance exists between the support and a bottom panel of the outer sliding rail, a locking bolt is arranged on the bottom panel of the outer sliding rail, the gear box fixing support can move above the locking bolt, and a transmission shaft of the driving motor is connected with a transmission assembly in the gear box. The structure is simple and compact, the requirement for the working power of the driving motor is relatively low, heating is reduced, abnormal sound and noise of the working condition are reduced, and larger total output power is guaranteed; space is saved, and installation efficiency is improved.
一种车辆座椅用电动滑轨的驱动机构,包括一对外滑轨,外滑轨上连接内滑轨,内滑轨的前后两端均设内滑轨滑动支撑架与消隙组件,外滑轨内腔中有丝杆;特点:驱动机构有滑动架板、驱动电机与齿轮箱,滑动架板竖向设在内滑轨的上表面上,驱动电机安装在滑动架板的中间;齿轮箱横向设在外滑轨内腔中并穿设在丝杆上;齿轮箱上还安装齿轮箱固定支架,该支架与内滑轨固定且与外滑轨底面板之间存在距离,外滑轨底面板上设锁定螺栓,齿轮箱固定支架能在锁定螺栓的上方运动,驱动电机的传动轴与齿轮箱内部的传动组件连接。结构简单紧凑,确保驱动电机的工作功率要求相对较小,减少发热并降低工况异响与噪声,保障更大的总输出功率;节约空间,提升安装效率。
