[0018] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0019] Example 1

[0020] See also Figures 1-4 , the utility model provides a technical solution for the assembly mechanism of the car seat slide rail:

[0021] A car seat slide rail assembly mechanism, Figures 1-4 , including an assembly seat 1, both sides of the upper surface of the assembly seat 1 are fixedly connected with a connecting plate 7, the upper surface of the assembly seat 1 is fixedly connected to a connecting rod 6 through two connecting plates 7, an inner side of the connecting rod 6 is provided with a limiting groove 17, and the inner side of the limiting groove 17 is rotatably connected to a bidirectional threaded rod 16, wherein the spirals on both sides of the outer wall of the bidirectional threaded rod 16 are mirror-symmetrical with the center point of the bidirectional threaded rod 16, and the outer wall spiral is set to twenty degrees, and both sides of the outer wall of the bidirectional threaded rod 16 are threadedly connected with a moving block 9, and a threaded connection is made between the bidirectional threaded rod 16 and the moving block 9, and the thread of the bidirectional threaded rod 16 is smaller than the equivalent friction angle of the spiral pair formed by the bidirectional threaded rod 16 and the moving block 9, forming a self-locking, preventing movement due to external reasons, wherein the moving blocks 9 on both sides of the outer wall of the bidirectional threaded rod 16 are mirror-symmetrical with the center point of the bidirectional threaded rod 16, and the size of the moving block 9 is consistent with the limiting The size of the groove 17 is matched, so that the two-way threaded rod 16 rotates and drives the moving blocks 9 on both sides to move toward each other along the inner wall of the limit groove 17. The upper surface of the assembly seat 1 is rotatably connected to several rotating plates 10 through the two moving blocks 9. One side of the outer wall of several rotating plates 10 is rotatably connected to a connecting seat 11. The upper surface of the assembly seat 1 is slidably connected to two limit plates 8 through several rotating plates 10 and several connecting seats 11. The moving block 9 is connected to the connecting seat 11 through the rotating plate 10, and the connecting seat 11 is connected to the limit plate 8. Then, when the two-way threaded rod 16 rotates and drives the moving blocks 9 on both sides to move toward each other along the inner wall of the limit groove 17, it drives several rotating plates 10 on both sides to rotate, thereby driving several rotating plates 10 on both sides to rotate, thereby driving the limit plates 8 on both sides to move back to back through the simultaneous rotation of several rotating plates 10, thereby achieving the effect of facilitating the adjustment of the spacing between the limit plates 8 on both sides.

[0022] Furthermore, a plurality of slide grooves 5 are provided on both sides of the upper surface of the assembly seat 1, and a slider 18 is slidably connected to one side of the inner side of the slide groove 5, and the slider 18 is connected to the limit plate 8. The size of the slide groove 5 matches the size of the slider 18, so that the slider 18 can move inside the slide groove 5, and is connected to the two limit plates 8 respectively through a plurality of slide grooves 5, so that the movement direction of the limit plate 8 is restricted, so that the limit plates 8 on both sides move toward or away from each other along the surface of the assembly seat 1. One side of the bidirectional threaded rod 16 extends to the outside of the connecting rod 6 and is fixedly connected to the knob 12, which is connected to one end of the bidirectional threaded rod 16 through the knob 12, so that rotating the knob 12 drives the bidirectional threaded rod 16 to rotate inside the limit groove 17.

[0023] Furthermore, positioning plates 2 are fixedly connected to both sides of the upper surface of the assembly seat 1, and a rotating shaft 13 is fixedly connected to the center position of the lower surface of the assembly seat 1. The lower surface of the assembly seat 1 is rotatably connected to the base 3 through the rotating shaft 13. The positioning plates 2 installed on the surface of the assembly seat 1 correspond to the limit plates 8, so that when the limit plates 8 on both sides are driven to move back to back along the surface of the assembly seat 1, the slide rail is pushed toward the outer wall of the positioning plate 2, so that the slide rail is fixed between the positioning plate 2 and the limit plate 8.

[0024] Furthermore, the interior of the base 3 is rotatably connected to a worm gear 15 via a rotating shaft 13, and the interior of the base 3 is rotatably connected to a worm 14 corresponding to one side of the worm gear 15, and the worm 14 extends to the outside of the base 3, and the worm gear 15 and the worm 14 are tightly engaged. The worm gear 15 inside the base 3 is installed on the outer wall of the rotating shaft 13, and the worm gear 15 and the worm 14 are tightly engaged, so that the rotation of the worm 14 drives the worm gear 15 to rotate inside the base 3, and then drives the rotating shaft 13 to rotate, and is connected to the assembly seat 1 through the rotating shaft 13, so as to facilitate the adjustment of the assembly angle of the top track of the assembly seat 1.

[0025] Furthermore, a servo motor 4 is fixedly connected to one side of the outer surface of the base 3, and the driving end of the servo motor 4 is fixedly connected to one side of the worm 14. The driving end of the servo motor 4 is connected to the worm 14, so that the servo motor 4 drives the worm 14 to rotate inside the base 3, and then drives the worm wheel 15 to rotate. Among them, the model of the worm 14 can preferably be HBS57, and an external power supply and control switch are connected when in use.

[0026] The implementation principle of the automobile seat slide rail assembly mechanism of the embodiment of the present application is as follows: when the device is in use, first, the two-way threaded rod 16 is driven to rotate inside the limit groove 17 by rotating the knob 12, so that the two-way threaded rod 16 rotates and drives the moving blocks 9 on both sides to move toward each other along the inner wall of the limit groove 17, and the moving block 9 is connected to the connecting seat 11 through the rotating plate 10, and the connecting seat 11 is connected to the limit plate 8, which then drives the multiple rotating plates 10 on both sides to rotate, and the multiple rotating plates 10 rotate at the same time, thereby pushing the limit plates on both sides. The plates 8 move back to back, pushing the slide rail toward the outer wall of the positioning plate 2, so that the slide rail is fixed between the positioning plate 2 and the limit plate 8, allowing the staff to assemble the slide rail. Subsequently, the driving end of the servo motor 4 is connected to the worm 14, so that the servo motor 4 drives the worm 14 to rotate inside the base 3, and the worm gear 15 and the worm gear 14 are tightly engaged, thereby driving the worm gear 15 to rotate, and then driving the rotating shaft 13 to rotate, and connecting with the assembly seat 1 through the rotating shaft 13, so that the top track assembly angle of the assembly seat 1 can be adjusted.
