Abstract

The invention discloses a novel transmission system of an electric long sliding rail, The sliding rail assembly comprises a left rail assembly and a right rail assembly, the left rail assembly comprises a slidably connected upper left rail and a lower left rail, the right rail assembly comprises a slidably connected upper right rail and a lower right rail, and the system comprises a slidably connected bridge with left and right sides fixed above the upper left rail and the upper right rail, respectively; A rack horizontally fixed in the inner grooves of the left lower rail and the right lowerrail; A driving motor connected to a middle lower surface of the slide rail connecting bridge; A transmission rod with a middle part connected with an output end of the drive motor; The transmission module comprises a housing, a driving gear and an output gear, wherein the output gear comprises an integrally formed meshing gear and a transmission gear. The transmission module is fixed inside the left upper rail and the right upper rail, respectively. The invention avoids the deflection problem of the filament rod in the long-stroke transmission, and effectively avoids the generation of abnormal sound.

Description

technical field [0001] The invention relates to the technical field of slide rails for automobile seats, in particular to a novel transmission system for electric long slide rails. Background technique [0002] At present, the adjustable slide rails in the front and rear direction of the car seat are divided into two types according to the driving mode: manual adjustment and electric adjustment. Among them, the basic structure of the electric adjustment slide rail is a motor bracket assembly and a pair of slide rail assemblies. The motor bracket assembly includes the drive motor and the bracket structure for fixing the motor. The torque is transmitted to the slide rail through the flexible shaft. The upper side of the slide rail is equipped with a gear box such as a worm gear, and the screw is fixed to the lower rail. Generally, the rotation of the motor is converted into the linear movement of the slide rail through the threaded auxiliary transmission of the nut in the gear...
