[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figure 1 — Figure 6 As shown, the utility model discloses an improved automobile seat slide rail structure comprising an outer rail frame 400 , an inner rail frame 100 , a fixing frame 200 , bolts 300 , a top plate 210 , a mounting plate 220 and a synchronous belt 500 .

[0027] The fixing frame 200 is connected to one side of the inner rail frame 100 by a bolt 300, one end of the bolt 300 extends into the inner rail frame 100, a top plate 210 is provided on the top of the fixing frame 200, and a mounting plate 220 connected to the bolt 300 is provided on one side of the top plate 210; the synchronous belt 500 passes through the fixing frame 200 and meshes with the inner wall of the fixing frame 200, the inner rail frame 100 is movably connected to the outer rail frame 400, a track 410 is provided inside the outer rail frame 400, at least two rollers (not marked in the figure) rollingly connected to the track 410 are provided at the bottom of the inner rail frame 100, and a mounting plate 220 for connecting the bolt 300 is provided on the side of the inner rail frame 100 Hole 120. When adjusting the car seat, the synchronous belt 500 will apply external force to the inner rail frame 100, and the inner rail frame 100 will change the position of the inner rail frame 100 on the inner rail frame 100 through the movement of the roller relative to the outer rail frame 400. During installation, people need to stick the mounting plate 220 of the fixing frame 200 to the side of the inner rail frame 100, and connect the mounting plate 220 and the inner rail frame 100 together through bolts 300. During this process, the synchronous belt 500 needs to pass through the fixing frame 200 and mesh with the fixing frame 200, so that the synchronous belt 500 can drive the fixing frame 200 and the inner rail frame 100 to move synchronously relative to the outer rail frame 400 during the movement.

[0028] Furthermore, one end of the bolt 300 extends into the inner rail frame 100, which can prevent the bolt 300 from being exposed, thereby reducing the space occupied by the bolt 300, so that the installation between the fixed frame 200 and the inner rail frame 100 is more compact. At the same time, it can also compress the Y-direction space of the synchronous belt while achieving smooth installation of the synchronous belt, that is, make the part of the synchronous belt located on the pressing plate closer to the side of the inner rail frame.

[0029] The interior of the fixing frame 200 is provided with an inner cavity 230 for the synchronous belt 500 to pass through, and the inner wall of the inner cavity 230 is provided with a tooth surface 240 meshing with the synchronous belt 500, and at least two positioning blocks 250 are provided on one side of the bottom of the inner cavity 230. The two sides of the inner rail frame 100 are provided with a rocker 110, and the rocker 110 is provided with a pressing plate 111, and the pressing plate 111 is inserted into the inner cavity 230, and each of the positioning blocks 250 is against the pressing plate 111. When installing, people need to pass the synchronous belt 500 through the inner cavity 230, and then, the mounting plate 220 needs to be connected with the inner rail frame 100. 0 is connected by bolts 300. During this process, the pressing plate 111 needs to be inserted into the inner cavity 230, and the two blocking blocks 250 are pressed against the pressing plate 111 at the same time, so that the pressing plate 111 can press the synchronous belt 500 located in the inner cavity 230 toward the tooth surface 240 until the synchronous belt 500 is engaged with the tooth surface 240. In this way, the synchronous belt 500, the fixed frame 200 and the inner rail frame 100 can be installed together more compactly. When the synchronous belt 500 moves, the synchronous belt 500 will simultaneously drive the fixed frame 200 and the inner rail frame 100 to move relative to the outer rail frame 400.

[0030] The distance between the seesaw 110 and the side of the inner rail frame 100 is greater than the distance between the pressing plate 111 and the side of the inner rail frame 100. In this way, people can reduce the width of the top plate 210, thereby reducing the lateral width of the fixing frame 200, thereby reducing the space occupied by the fixing frame 200, thereby compressing the Y-direction space of the synchronous belt, that is, making the part of the synchronous belt located at the pressing plate closer to the side of the inner rail frame.

[0031] The rocker 110 is provided with an opening 112 for the top plate 210 to pass through at the pressing plate 111 . When the mounting plate 220 and the inner rail frame 100 are threaded together, the rocker 110 just passes through the opening 112 , so that the fixing frame 200 can be smoothly installed on the side of the inner rail frame 100 .

[0032] A rib plate 260 is provided between the mounting plate 220 and the top plate 210. The rib plate 260 is triangular in shape as a whole. The provision of the rib plate 260 can effectively improve the connection strength between the mounting plate 220 and the top plate 210, that is, effectively improve the connection strength between the mounting plate 220 and the fixing frame 200.
