Problems solved by technology
from Figure 1 to Figure 4 It can be seen that the connection between the screw assembly and the upper slide rail 1, especially the connection between the worm gear box assembly 3 in the screw assembly and the upper slide rail 1 requires a mounting bracket for the worm gear box assembly 4 and screw 17 increase the weight of the electric slide rail at the front of the entire car seat, complicate the installation structure, and the comprehensive tolerance after assembly is large, which is not conducive to quality control and sound performance improvement

Embodiment Construction
[0034] see Figure 6 to Figure 17 , a car seat front electric slide rail shown in the figure includes upper and lower rails 100, 200, upper and lower ball cage assemblies 300, 400, screw assembly 500, worm gear box 600, Nut assembly 700, rear bracket assembly 800.
[0035] Viewed from the cross-sectional direction, the upper slide rail 100 has a top surface 110, left and right inner surfaces 120, 130, left and right outer surfaces 140, 150 and connecting left and right inner surfaces 120, 130 with left and right outer surfaces. Left and right bottom surfaces 160,170 between 140,150.
[0036] After the upper and lower rails 100, 200 are assembled together according to the existing method, the lower steel ball cage assembly 300, 400 is also arranged between the upper and lower rails 100, 200 according to the existing method, and the upper and lower steel balls are kept The upper and lower steel ball groups in the frame assembly 300, 400 promote relative linear sliding between ...

The invention discloses a front electric sliding rail of an automobile seat. The front electric sliding rail of the automobile seat comprises an upper sliding rail body, a lower sliding rail body, an upper steel ball retainer assembly, a lower steel ball retainer assembly, a lead screw assembly, a worm and worm wheel box, a nut assembly and a rear support assembly, wherein the upper steel ball retainer assembly and the lower steel ball retainer assembly are arranged between the upper sliding rail body and the lower sliding rail body; the lead screw assembly comprises a lead screw and a worm and worm wheel assembly arranged at the front end of the lead screw; the worm and worm wheel box is used for containing and assembling the worm and worm wheel assembly; the nut assembly is fixedly connected with the lower sliding rail body; a nut in the nut assembly is in screwed connection with the lead screw in the lead screw assembly; the rear end of the lead screw in the lead screw assembly is supported and connected to the upper sliding rail body through the rear support assembly; the worm and worm wheel box and the upper sliding rail body are assembled together in an insert block and socket mode. The mode that a screw and a worm and worm wheel box assembly installation support are fixedly connected in the prior art is not needed, the number of parts is reduced, and therefore the weight of the whole front electric sliding rail is reduced.
