[0002] Regarding current car seats, in order to accommodate passengers of various body types, car seats can usually slide forward and backward to accommodate different body sizes. However, the existing car seat long sliding rails are completely independent of the car body. The main rail of the long sliding rail is fixed to the car body with bolts, and it also requires auxiliary components such as mounting brackets for fixation. For a long sliding rail with a length of 2.5m, in order to ensure the connection strength between the long sliding rail and the car body, 10 bolts are required for each rail, and 4 rails for a car require 40 bolts. Adding the assembly time of the mounting brackets, the assembly time of the entire long sliding rail is very long, and the installation cost is high. In addition, for a long sliding rail with a length of 2.5m, the main rail weighs about 6.8KG, and 4 rails for a car weigh about 27KG, making the installation weight of the long sliding rail quite heavy.

[0003] The technical problem to be solved by this application is: how to reduce the assembly time of long slide rails for automobile seats and how to reduce the weight of long slide rails. Utility Model Content

The female rail ball track is set in the downward recessed position of the body panel. The two sides of the female rail ball track are connected to the body panel. The two sides of the female rail ball track are respectively connected to the corresponding female rail flange. The male rail screw is fixedly set in the female rail ball track.

[0006] In some embodiments, a number of crossbeams are arranged below the vehicle body panels, and the crossbeams have load-bearing grooves at positions corresponding to the main rail ball track, with the main rail ball track embedded in the load-bearing grooves.

[0007] In some implementations, the two ends of the male rail lead screw are fixedly connected to the female rail ball track.

[0008] In some implementations, the body panel and the mother rail ball track are integrally formed.

[0025] Please see Figures 1-4 A long sliding rail structure with integrated body, including body panel 1, mother rail ball track 2, mother rail flange 3, public rail screw 4 and crossbeam 5.

[0026] The mother rail track 2 is fixedly mounted on the body panel 1, and the body panel 1 and the mother rail track 2 are integrally formed. The mother rail track 2 is U-shaped, forming a downwardly recessed groove in the body panel 1. The thickness of the mother rail track 2 is greater than the thickness of the rest of the body panel 1, that is, the thickness of the body panel 1 at the position of the mother rail track 2 is greater than the thickness of the rest of the body panel 1. Corresponding mother rail flanges 3 are provided on both sides of the mother rail track 2. One side of the mother rail flange 3 is fixedly connected to the body panel 1 by bolts. The male rail screw 4 is set in the mother rail track 2, and both ends of the male rail screw 4 are fixedly connected to the mother rail track 2. Several crossbeams 5 are set below the body panel 1. The crossbeams 5 have load-bearing grooves 51 at the corresponding positions of the mother rail track 2. The mother rail track 2 is embedded in the load-bearing grooves 51, so that the crossbeams 5 can adapt to the bottom shape of the body panel 1, thereby improving the load-bearing capacity of the body panel 1.

[0027] To further reduce assembly time, in this embodiment, preferably, the mother rail flange 3 is provided with a buckle 31, and the body panel 1 is provided with a hole 11. The buckle 31 and the hole 11 are snapped together. The two ends of the mother rail flange 3 are respectively fixedly connected to the body panel 1 by bolts to reinforce the position of the mother rail flange 3 on the body panel 1, reduce the assembly of bolts, and thus reduce assembly time.

[0028] This embodiment reduces some components such as the anchor bracket.
