[0013] The present invention provides a vehicle seat structure integrating a slide rail and shock absorption. It has the following beneficial effects: For the vehicle seat structure integrating a slide rail and shock absorption, through the setting of a shock absorption assembly, a locking assembly and a weight adjustment assembly, the shock absorption function, sliding function and adjustment function of the seat are designed integrally. In the existing traditional seat design, the slide rail mechanism and the shock absorption system are mostly independent modules, resulting in complex installation and low space utilization rate. Through the combined design of an internal slide rail, a scissor rod shock absorption and a conical spring adjustment, the space layout is optimized, so that the seat has high stability and comfort on the basis of light weight.

[0014] For the vehicle seat structure integrating a slide rail and shock absorption, through the setting of a shock absorption assembly, shock absorption treatment is carried out on the seat. Through the sliding of the first slider and the third slider at the front side and the sliding of the second slider at the rear upper part, and driven by the rear link of the scissor rod, the first slider, the second slider and the third slider on both sides move together, converting the up-and-down movement of the seat into the front-and-back sliding of the slider, and shock absorption treatment is carried out on the seat in a limited space.

[0015] For the vehicle seat structure integrating a slide rail and shock absorption, through the setting of a locking assembly, the opening or closing of the rear upper slide rail is controlled. By manually rotating the slide rail handle, the tooth-shaped protrusion on the rotary locking piece is rotated out of the hole on the slide rail, thereby unlocking the function of the rear upper slide rail of the seat. At this time, the rear upper slide rail is in an open state, and the slide rail locking return spring is deformed; then the slide rail locking return spring gradually returns to its original state, causing the rotary locking piece to rotate back to its original position, and the tooth-shaped protrusion on the rotary locking piece enters the hole of the rear upper slide rail, locking the slide rail. At this time, the rear upper slide rail is in a closed state.

[0016] The integrated slide rail and shock-absorbing vehicle seat structure performs weight adjustment work on the seat by setting a weight adjustment component. By manually adjusting the height after the fixing bolt and nut are engaged, the upward movement limit position of the seat is restricted. By manually adjusting the weight adjustment handle, the adjustment nut is controlled to move back and forth. As the adjustment nut moves, the washer contacts and drives the crank to rotate around the crank rotation axis. The crank connecting shaft drives the guide piece to move, and the guide piece drives the upper weight adjustment block to move. The wedge-shaped structure on the upper weight adjustment block converts the back-and-forth movement into the up-and-down movement of the lower weight adjustment block, thereby adjusting the initial compression amount of the tower spring, and further adjusting the initial stiffness of the tower spring to achieve the function of weight adjustment. And by setting the washer, the friction between the protrusion and the guide piece can be reduced, and at the same time, the noise generated when the protrusion contacts the guide piece can be reduced.

The crank connecting shaft 606 drives the guide piece 607 to move, and the guide piece 607 drives the upper weight adjustment block 602 to move. The wedge-shaped structure on the upper weight adjustment block 602 converts the back-and-forth movement into the up-and-down movement of the lower weight adjustment block 601, thereby adjusting the initial compression amount of the tower spring 609, and further adjusting the initial stiffness of the tower spring 609 to achieve the function of weight adjustment. And by setting up the washer 613, the friction between the protrusion 608 and the guide piece 607 can be reduced, and at the same time, the noise generated when the protrusion 608 contacts the guide piece 607 can be reduced.

[0034] Working principle: Before use, by manually rotating the slide rail handle 501, the slide rail handle 501 drives the slide rail operating rod 505 to rotate, and the slide rail operating rod 505 drives the rotary locking piece 503 to rotate. The tooth-shaped protrusions on the rotary locking piece 503 rotate out from the holes on the slide rail, thereby unlocking the function of the slide rail on the upper rear side of the seat. At this time, the slide rail locking return spring 504 deforms.

[0035] Before using the device, manually adjust the height after the engagement of the fixing bolt 614 and the nut to restrict the upper limit position of the seat moving upward. When the driver manually adjusts the weight adjustment handle 610, the weight adjustment handle 610 drives the weight adjustment screw rod 11 to rotate, so that the adjusting nut 603 on the weight adjustment screw rod 11 moves back and forth. The protrusion 608 on the adjusting nut 603 contacts the washer 613. During the movement of the adjusting nut 603, the washer 613 contacts and drives the crank 604 to rotate around the crank rotation shaft 605. The crank connecting shaft 606 drives the guide piece 607 to move, and the guide piece 607 drives the upper weight adjustment block 602 to move. The wedge-shaped structure on the upper weight adjustment block 602 converts the back-and-forth movement into the up-and-down movement of the lower weight adjustment block 601, thereby adjusting the initial compression amount of the tower spring 609, and further adjusting the initial stiffness of the tower spring 609 to achieve the function of weight adjustment.

[0036] When carrying out the seat shock absorption work, the scissors rod one 401 drives the third slider 406 to slide in the front lower slide rail 10. At the same time, the scissors rod one 401 drives the first slider 404 to slide in the rear upper slide rail 8. The scissors rod two 402 drives the second slider 405 to slide in the front upper slide rail 9. Through the sliding of the first slider 404 and the third slider 406 on the front side and the sliding of the second slider 405 on the rear upper side, the up-and-down movement of the seat is converted into the back-and-forth sliding of the sliders. At this time, the cushion frame 2 and the bottom plate 7 move relative to each other back and forth, playing the function of sliding.

[0037] Subsequently, the slide rail locking return spring 504 gradually returns to its original state, causing the rotary locking piece 503 to rotate back. The tooth-like protrusion on the rotary locking piece 503 enters the hole of the rear upper slide rail 8, locking the slide rail.
