The application is provided with two slide rails 002 arranged in parallel to support the seat and guide the sliding of the seat, while the two slide rails 002 are evenly stressed, and the sliding of the seat can be smoother. Among them, the lower rail 002 of the two slide rails 002 is used to fix to the body, and the upper rail 02 is used to attach the seats.

The transaxle 002 is vertically connected between the two slides 002 and connected to the upper rail 02 of the two slides 002, which is used to drive the two upper rails 02 to slide synchronously, and then drive the seat to slide.

The seat slide rail in the embodiment of the present application, using the slide rail in the aforementioned embodiment, when the car collides, resulting in a large peeling force of the seat belt on the slide rail, the slide rail can withstand a larger peeling force to ensure the safety of the occupants.

In one embodiment, the drive axle 001 is provided with a drive motor 06, the drive motor 06 is connected to the upper rail 02 of one of the slide rail 002, and by driving the upper rail 02 of one of the slide rail 002 to slide relative to the lower rail 01, driving the seat and the upper rail 02 of the other slide rail 002 to slide synchronously.

Specifically, the slide rail further comprises a worm 04 and a worm box 05 that is sliding mounted on the worm 04, the worm 04 is mounted on the lower rail 01, and the worm box 05 is connected to the upper rail 02;

The output shaft of the drive motor 06 is connected to the worm box 05 of one of the slide rails 002 for driving the worm box 05 to slide along the worm 04.

In an embodiment of the present application, the drive motor 06 drives the worm box 05 to slide relative to the worm 04, driving the upper rail 02 to slide relative to the lower rail 01, thereby driving the seat to slide, realizing the electric drive of the seat.

Vehicle:

The technical solution of the present application also provides a vehicle, comprising a slide rail as described in the foregoing embodiment and / or a seat rail as described in the foregoing embodiment.

The vehicle in the embodiment of the present application includes the slide rail and / or seat slide provided in the aforementioned embodiment, because the vehicle in the embodiment of the present application has the same advantages as the slide rail and / or seat slide provided in the aforementioned embodiment, it will not be repeated herein.

The foregoing is only the principle of the present application and a better embodiment. It should be noted that for those of ordinary skill in the art, the embodiments obtained by appropriate combinations of technical solutions disclosed separately in different embodiments are also included in the scope of the present invention, and on the basis of the principles of the present application, certain other variants may also be made, which should also be regarded as the scope of protection of the present application.
