[0021] Example

[0022] See also Figures 1 to 4 In this embodiment, the seat slide rail with an external rear stop point includes a motor assembly 3 and a right slide rail 1 and a left slide rail 2 with the same structure and symmetrical to each other. The right slide rail 1 and the left slide rail 2 are connected through the motor assembly 3.

[0023] In this embodiment, the right slide rail 1 includes a right front mounting angle 11, a right rear mounting angle 12 and a right slide rail body 13, wherein the right front mounting angle 11 and the right rear mounting angle 12 are connected through the right slide rail body 13; the right front mounting angle 11 and the right rear mounting angle 12 are in opposite directions, the right front mounting angle 11 is installed downward, and the right rear mounting angle 12 is installed upward (the upward and downward methods are shown in FIG. Figure 1 The right rear mounting angle 12 is provided with a rear stop point 121, which is connected to the right rear mounting angle 12 as a whole; the motor assembly 3 is located in front of the right slide rail 1 and the left slide rail 2.

[0024] In this embodiment, the left slide rail 2 includes a left front mounting corner 21, a left rear mounting corner 22 and a left slide rail body 23. The left front mounting corner 21 and the left rear mounting corner 22 are connected via the left slide rail body 23; the left rear mounting corner 22 is also provided with a rear stop point 121.

[0025] In this embodiment, the right slide rail body 13 includes an upper slide rail 131, a lower slide rail 132, a front screw assembly 133, a screw nut 134, a retainer 135, a retainer 2 136 and a screw connecting sleeve 137. The front screw assembly 133 is provided with a gear box 1331 and a shaft head 1332. The front screw assembly 133 is fixed to the upper slide rail 131, the screw connecting sleeve 137 is installed on the upper slide rail 131, the shaft head 1332 is sleeved with the screw connecting sleeve 137, the screw nut 134 is threadedly matched with the front screw assembly 133, and the screw nut 134 is installed on the lower slide rail 132. The retainer 135 and the retainer 2 136 have the same structure and are respectively arranged between the upper slide rail 131 and the lower slide rail 132, and are rollingly matched with the upper slide rail 131 and the lower slide rail 132.

[0026] In this embodiment, the motor assembly 3 includes a motor body 31, a motor connector 1 32 and a motor connector 2 33. One end of the motor body 31 is screwed to the motor connector 1 32, and the other end of the motor body 31 is screwed to the motor connector 2 33. The motor connector 1 32 is connected and fixed to the right slide rail body 13, and the motor connector 2 33 is fixed to the left slide rail body in the left slide rail 2.

[0027] In this embodiment, a drive shaft 1 310 and a drive shaft 2 311 are provided on the motor body 31 , a gear box 2 2331 is provided in the left slide rail body of the left slide rail 2 , the drive shaft 1 310 is connected to the gear box 1 1331 , and the drive shaft 2 311 is connected to the gear box 2 2331 .

[0028] In this embodiment, the lower sliding rail 132 of the right sliding rail body 13 is riveted to the right front installation corner 11 and the right rear installation corner 12 respectively.

[0029] The working process of the seat slide rail with an external rear stop point in this embodiment is as follows: the motor body 31 works to drive the drive shaft 310 to rotate, and then drives the gear box 1331 to work to drive the front screw assembly 133 to rotate, so that the front screw assembly 133 produces axial displacement relative to the screw nut 134, and the front screw assembly 133 drives the upper slide rail 131 to slide.

[0030] When the outer cushion bracket is completed, the rear stop point 121 interferes with the cushion bracket to achieve the function of limiting the right slide rail body 13 to the rear, and the left slide rail body 23 on the other side also has the same action principle.

[0031] The right front mounting angle 11, the right rear mounting angle 12 and the right slide rail body 13 of the right slide rail 1 are assembled on site after transportation. When the right front mounting angle 11 is riveted, the right slide rail 1 moves backward, and when the right rear mounting angle 12 is riveted, the right slide rail 1 moves forward. When the right rear mounting angle 12 is assembled with the external seat cushion bracket, it reaches the limit position through the rear stop point 121; the same applies to the assembly of the left slide rail 2.

[0032] Through the above description, those skilled in the art can already implement it.
