Toothed windows are arranged on both sides of the upper rail. The locking pawl is connected to the upper rail through the tension spring. The sliding bearing assembly is connected to the upper rail. Toothed windows are arranged on both sides of the lower rail. The teeth of the locking pawl can move up and down in the toothed windows of the lower rail. When the locking pawl is kept stationary by the upward force of the tension spring, the teeth of the locking pawl enter the toothed windows on both sides of the lower rail to achieve locking.

[0005] In the aforementioned automotive seat slide rail locking structure, there are two tension springs. The upper rail and the locking claw are connected by the two tension springs. The gap elimination component is connected to the upper rail by riveting. The sliding bearing assembly is connected to the upper rail by riveting. After the upper rail, tension springs, gap elimination component, sliding bearing assembly, and locking claw are assembled, they are slidably installed into the cavity of the lower rail.

[0006] In the aforementioned car seat slide rail locking structure, the upper rail includes an upper rail body with a U-shaped cross section and upper bending portions located on both sides of the upper rail body and bending outwards. The upper rail body is provided with U-shaped side tooth windows on both sides. The locking claw is connected to the upper rail through a tension spring, and the claw teeth of the locking claw can move up and down in the side tooth windows of the upper rail.

[0007] In the aforementioned automotive seat slide rail locking structure, the lower rail includes a U-shaped lower rail body and lower bent portions located on both sides of the lower rail body and bent inwards. U-shaped locking tooth windows are arranged on both sides of the lower bent portions. The teeth of the locking pawl can move up and down in the locking tooth windows of the lower rail. When the locking pawl is kept stationary by the upward force of the tension spring, the teeth of the locking pawl enter the locking tooth windows on both sides of the lower bent portion of the lower rail body to achieve locking.

[0014] In the figure, the upper rail is 100; the upper rail body is 101; the upper bend is 102; the side toothed window is 103; the lower rail is 200; the lower rail body is 201; the lower bend is 202; the locking toothed window is 203; the tension spring is 300; the guide rod is 400; the locking pawl is 500; the gap elimination assembly is 600; and the sliding bearing assembly is 700.

[0015] like Figure 1 as well as Figure 2As shown, the locking structure of this car seat slide rail includes an upper rail 100, a lower rail 200, a tension spring 300, a locking pawl 500, a gap elimination assembly 600, and a sliding bearing assembly 700. Toothed windows are arranged on both sides of the upper rail 100. The locking pawl 500 is connected to the upper rail 100 through the tension spring 300, and the sliding bearing assembly 700 is connected to the upper rail 100. Toothed windows 203 are arranged on both sides of the lower rail 200. The teeth of the locking pawl 500 can move up and down in the toothed windows 203 of the lower rail 200. When the locking pawl 500 is kept stationary by the upward force of the tension spring 300, the teeth of the locking pawl 500 enter the toothed windows 203 on both sides of the lower rail 200 to achieve locking.

[0016] Specifically, to achieve locking and unlocking, this embodiment uses two tension springs 300. The upper rail 100 and the locking pawl 500 are connected by two tension springs 300. The gap-eliminating component 600 is connected to the upper rail 100 by riveting. The sliding bearing assembly 700 is also connected to the upper rail 100 by riveting. After the upper rail 100 is assembled with the tension springs 300, the gap-eliminating component 600, the sliding bearing assembly 700, and the locking pawl 500, it is slidably installed into the cavity of the lower rail 200. Here, the upper rail 100 includes an upper rail body 101 with a U-shaped cross-section and upper bent portions 102 located on both sides of the upper rail body 101 and bent outwards. U-shaped locking pawls 500 are arranged on both sides of the upper rail body 101. The locking pawls 500 are connected to the upper rail 100 by tension springs 300. The teeth of the locking pawls 500 can move up and down in the side toothed windows 103 of the upper rail 100. The lower rail 200 includes a U-shaped lower rail body 201 and lower bent portions 202 located on both sides of the lower rail body 201 and bent inwards. U-shaped locking tooth windows 203 are arranged on both sides of the lower bent portions 202. The teeth of the locking pawl 500 can move up and down within the locking tooth windows 203 of the lower rail 200. When the locking pawl 500 is held stationary by the upward force of the tension spring 300, the teeth of the locking pawl 500 enter the locking tooth windows 203 on both sides of the lower bent portions 202 of the lower rail body 201 to achieve locking. When the locking pawl 500 is subjected to downward force, the teeth of the locking pawl 500 disengage from the locking tooth windows 203 on both sides of the lower bent portions 202 of the lower rail body 201 to achieve unlocking. Thus, the locking tooth windows 203 and the side tooth windows 103 ensure the movement position of the locking pawl 500, achieving the locking function of the upper rail 100; disengagement unlocks the upper rail. Figure 3 As shown, the locking pawl 500 has a guide rod 400. One end of the guide rod 400 is connected to the locking pawl 500, and the other end is inserted into the guide hole of the upper rail body 101. This ensures the movement direction of the locking pawl 500 and guarantees the stability of locking and unlocking.
