[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-6 , an installation structure of an automobile seat, including a headrest 1. A connecting column 2 is fixedly connected to the bottom of the headrest 1. The bottom end of the connecting column 2 is fixedly connected to a backrest 3. The bottom of the convex side of the backrest 3 is fixedly connected to a seat cushion 4. The outer wall of the bottom side of the seat cushion 4 is threadedly connected to a slide rail 5. The bottom of the slide rail 5 is slidably connected to a rail plate 6. The bottom of the rail plate 6 is provided with a bottom plate assembly 7;

[0033] On the outer walls of the top ends on both sides of the rail plate 6, two tracks 601 are fixedly connected. Through grooves 602 are opened on the outer walls of the opposite sides of the two tracks 601. Rectangular grooves 603 are opened on the outer walls of the two tracks 601 on the far sides. A number of groups of square grooves 604 are opened at the bottom of the inner wall of the rectangular groove 603. A round block one 605 is fixedly connected to the bottom of the rail plate 6. A connecting rod 606 is fixedly connected to the outer wall of the round block one 605. The bottom end of the connecting rod 606 is fixedly connected to a circular clamping plate 608. Triangular grooves 607 are opened on both sides of the circular clamping plate 608 near one end of the connecting rod 606;

[0034] The bottom plate assembly 7 includes a bottom plate one 710. A limiting block two 701 and a round block two 702 are respectively fixedly connected to the top of the bottom plate one 710. A rotating shaft 703 is fixedly connected in a circular shape on the outer wall of the round block two 702. A double sleeve 704 and a single sleeve 705 are respectively sleeved on the outer wall of the rotating shaft 703. A double clamping leaf 707 and a single clamping leaf 706 are respectively fixedly connected to the tops of the double sleeve 704 and the single sleeve 705. Triangular blocks 709 are fixedly connected to the outer walls of the opposite sides of the single clamping leaf 706 and the double clamping leaf 707. Pressure springs 708 are respectively fixedly connected to the bottoms of the single clamping leaf 706 and the double clamping leaf 707 on the sides far from the rotating shaft 703.

[0035] Among them, a fixing plate 501 is fixedly connected to the bottom of the slide rail 5. Fixing screws 502 are sleeved on both sides of the fixing plate 501. A rod hole 503 is opened on the outer wall of the middle part of the slide rail 5;

[0036] A pull rod 504 is arranged on the top of the rail plate 6. Limiting rods 505 are fixedly connected to both ends of the pull rod 504. The limiting rods 505 are sleeved in the inner wall of the rod hole 503. A bearing 506 is fixedly sleeved on the outer wall of the limiting rod 505 near one end of the pull rod 504. A limiting block one 507 located on the inner wall of the rectangular groove 603 is fixedly connected to one end of the limiting rod 505 close to the square groove 604.

[0037] It should be noted that the sliding rail 5 is fixed by being threadedly connected to the seat cushion 4 through the fixing screw 502. By passing the limiting rod 505 through the rod hole 503, when the pull rod 504 is pulled, the pull rod 504 is pressed to drive the sliding rail 5, and the sliding rail 5 drives the seat cushion 4 of the seat to slide in the same direction.

[0038] Among them, the bearing 506 is slidably sleeved on the inner wall of the through groove 602. A convex portion is provided at the end of the pull rod 504 close to the limiting rod 505, and the diameter of the rod hole 503 is larger than the diameter of the limiting rod 505.

[0039] It should be noted that since the diameter of the rod hole 503 is larger than the diameter of the limiting rod 505, the limiting rod 505 can move in the rod hole 503. Thus, when the pull rod 504 is pulled upward, the end of the pull rod 504 moves downward. At the same time, when one end of the limiting rod 505 close to the pull rod 504 is pressed, one end of the pull rod 504 close to the limiting block one 507 moves upward, causing the limiting block one 507 to separate from the square groove 604.

[0040] Among them, there are four groups of connecting rods 606, and the positions of the four groups of connecting rods 606 correspond to the position of the rotating shaft 703;

[0041] The circular clamping plate 608 is clamped by the single clamping leaf 706 and the double clamping leaf 707, and the triangular block 709 is engaged with the triangular groove 607.

[0042] It should be noted that through the triangular block 709 and the triangular groove 607, the seat cushion 4 of the seat is made more firm, thereby reducing potential safety hazards.

[0043] Among them, there are four groups of limiting blocks two 701, and there are four groups of rotating shafts 703. One end of the four groups of rotating shafts 703 far from the round block two 702 is fixedly connected to the limiting blocks two 701.

[0044] It should be noted that through the position limitation of the four groups of rotating shafts 703, the four groups of limiting blocks two 701, and the round block two 702, the force transmission of the vehicle seat is made uniform.

[0045] Among them, the space between the single clamping leaf 706 and the double clamping leaf 707 is adapted to the circular clamping plate 608. The shape of the triangular block 709 coincides with the triangular groove 607, and the top end of the compression spring 708 is fixedly connected to the bottom sides of the single clamping leaf 706 and the double clamping leaf 707.

[0046] It should be noted that when the single-card connecting leaf 706 and the double-card connecting leaf 707 are squeezed downward, the pressure spring 708 is simultaneously squeezed downward. After the single-card connecting leaf 706 and the double-card connecting leaf 707 are squeezed on the circular clamping plate 608 to a state where they can stop between the single-card connecting leaf 706 and the double-card connecting leaf 707 by themselves, the single-card connecting leaf 706 and the double-card connecting leaf 707 are no longer squeezed. The pressure spring 708 supports the single-card connecting leaf 706 and the double-card connecting leaf 707 to return to their original positions due to its elastic force, enabling the triangular block 709 to be clamped with the triangular groove 607, thereby realizing a fast installation function.

[0047] Working principle: The installer presses the rail plate 6 downward, causing the connecting rod 606 to drive the circular clamping plate 608 downward. When the circular clamping plate 608 moves downward, it squeezes the single-card connecting leaf 706 and the double-card connecting leaf 707, causing the pressure spring 708 to be compressed under pressure. After the circular clamping plate 608 squeezes the single-card connecting leaf 706 and the double-card connecting leaf 707 to a state where they can stop between the single-card connecting leaf 706 and the double-card connecting leaf 707 by themselves, the pressure spring 708 will return the single-card connecting leaf 706 and the double-card connecting leaf 707 to their original positions due to its elastic force, enabling the single-card connecting leaf 706 and the double-card connecting leaf 707 to perform a clamping action, and causing the triangular block 709 to be clamped with the triangular groove 607. The installer selects a seat cushion 4 with different widths. The seat cushion 4 is threadedly connected to the fixing plate 501 through the fixing screw 502, enabling the slide rail 5 to be placed in the track 601 corresponding to the position of the slide rail 5, enabling the bearing 506 to slide on the inner wall of the through groove 602. By pulling up the pull rod 504, the end of the pull rod 504 is pressed downward. One end of the limiting rod 505 close to the pull rod 504 moves downward due to the pressure, while the other end of the limiting rod 505 far from the pull rod 504 will move upward. Through the upward movement of the end of the limiting rod 505 far from the pull rod 504, the limiting block one 507 is separated from the square groove 604. The limiting rod 505 is sleeved in the rod hole 503, so that when the pull rod 504 is pulled, the limiting rod 505 applies pressure to the slide rail 5, and the slide rail 5 slides in the direction of the pull of the pull rod 504, thereby driving the entire seat.

[0048] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
