The slide rail assembly is generally two sets, symmetrically arranged on the vehicle body floor, and each set of slide rails consists of an upper slide rail and a lower slide rail. The upper slide rail is installed under the seat pan, and the lower slide rail is installed on the vehicle body floor. The upper slide rail slides forward and backward in the lower slide rail to achieve the front and rear adjustment of the seat.

[0003] In the early technology of seat slides, after the slides are assembled on the vehicle, the drive motor is located between the two sets of slides. The drive motor provides driving force from the inner side of the two sets of slides close to each other to the worm gear box inside the slides to control the upper slide to slide on the lower slide. Since the drive motor transmits driving force from the inner side of the slides to the gear box, after assembly, the upper and lower slide rail components are exposed on the vehicle floor. For commercial vehicles and other vehicles that require a longer slide travel, the slides are exposed on the vehicle body floor, occupying the space for passengers to move around in the vehicle, and greatly affecting the interior of the vehicle, seriously reducing the high-end feel of the vehicle;

[0004] Secondly, in the prior art, the upper part of the upper slide rail is in a sheet-like structure, and the lower part is in a block-like structure.
