[0033] The crank connecting shaft is arranged inside the crank.

[0034] Preferably, the weight adjustment component further comprises:

[0035] A guide plate, the guide plate being mounted on the outside of the crank connecting shaft, and a through groove being formed inside the guide plate;

[0036] The tower spring has a smaller diameter side that contacts the weight lower adjustment block, and a larger diameter side that contacts the bottom plate.

[0037] The present invention provides a vehicle seat structure with integrated slide rails and shock absorption. It has the following beneficial effects:

[0038] This integrated sliding rail and shock-absorbing vehicle seat structure integrates shock absorption, sliding, and adjustment functions by providing a shock-absorbing component, a locking component, and a weight adjustment component. In existing traditional seat designs, the sliding rail mechanism and shock-absorbing system are often separate modules, resulting in complex installation and low space utilization. By combining the built-in sliding rail with scissor lever shock absorption and tower spring adjustment, the space layout is optimized, ensuring the seat is lightweight while maintaining high stability and comfort.

[0039] This vehicle seat structure with integrated slide rails and shock absorption utilizes a shock-absorbing assembly to provide seat vibration reduction. By sliding the first and third sliders at the front and the second slider at the rear, driven by the rear link of the scissor lever, the first, second, and third sliders on both sides move together, converting the seat's up-and-down motion into forward and backward sliding motion of the sliders, providing seat vibration reduction within a limited space.

[0040] This vehicle seat structure with integrated slide rails and shock absorption utilizes a locking assembly to control the opening and closing of the rear upper slide rail. Manually turning the slide rail handle causes the tooth-like protrusion on the rotary locking plate to rotate out of the hole in the slide rail, thereby unlocking the slide rail on the rear upper side of the seat. The rear upper slide rail is now in the open position, and the slide rail lock return spring deforms. The slide rail lock return spring then gradually returns to its original position, allowing the rotary locking plate to rotate back to its original position. The tooth-like protrusion on the rotary locking plate enters the hole in the rear upper slide rail, locking the slide rail and closing it.

[0041] This vehicle seat structure with integrated slide rails and shock absorbers utilizes a weight adjustment assembly to adjust the seat's weight. The seat's upper limit of upward movement is limited by manually adjusting the height of the engaged fixing bolt and nut. The weight adjustment handle is manually adjusted to control the forward and backward movement of the adjustment nut. As the adjustment nut moves, the washer contacts and drives the crank around its axis of rotation. The crank's connecting shaft drives the guide plate, which in turn drives the upper weight adjustment block. The wedge-shaped structure on the upper weight adjustment block converts the forward and backward movement into the up and down movement of the lower weight adjustment block, thereby adjusting the initial compression of the tower spring and, in turn, the initial stiffness of the tower spring to achieve weight adjustment. The washer reduces friction between the protrusion and the guide plate, while also reducing the noise generated when the protrusion and the guide plate come into contact.

[0054] The weight adjustment screw 11 is installed inside the bracket 3, and the weight adjustment component 6 is provided outside the weight adjustment screw 11;

[0055] The rear upper slide rail 8 is provided at the bottom of the bracket 3. A hole is provided inside the rear upper slide rail 8. There are multiple holes, which are evenly arranged. There are two rear upper slide rails 8, which are symmetrically arranged.

[0056] The shock absorbing assembly 4 is arranged inside the cushion frame 2 and includes a first slider 404, a second slider 405 and a third slider 406. The first slider 404 is slidably connected to the inside of the rear upper slide rail 8;

[0057] The locking assembly 5 is arranged on the outside of the rear upper slide rail 8. The locking assembly 5 includes a slide rail handle 501 and a rotary locking plate 503. The rotary locking plate 503 is provided with a tooth-like protrusion on the outside. The slide rail handle 501 controls the opening or closing of the rear upper slide rail 8 by controlling the rotation of the tooth-like protrusion on the outside of the rotary locking plate 503.

[0058] The front upper slide rail 9 is provided at the bottom of the bracket 3. The second slider 405 is slidably connected to the interior of the front upper slide rail 9. There are two front upper slide rails 9, which are symmetrically arranged.

[0059] The front lower sliding rail 10 is arranged on the top of the bracket 3, and the third slider 406 is slidably connected to the inside of the front lower sliding rail 10. There are two front lower sliding rails 10, and they are symmetrically arranged.

[0060] Before use, adjust the locking assembly 5 so that the rear upper slide rail 8 is in the open state, and manually adjust the weight adjustment assembly 6. Then the shock absorbing assembly 4 is enabled and the seat shock absorbing work is started.

[0061] The shock absorbing assembly 4 further includes:

[0062] A scissor lever 401 is provided, wherein one end of the scissor lever 401 close to the backrest frame 1 is connected to the first slider 404, and the other end of the scissor lever 401 away from the backrest frame 1 is connected to the third slider 406. The scissor lever 401 drives the first slider 404 and the third slider 406 to move. Two scissor levers 401 are provided and are symmetrically arranged.

[0063] A second scissor lever 402 , wherein one end of the second scissor lever 402 away from the backrest frame 1 is connected to the second slider 405 , and the second scissor lever 402 drives the second slider 405 to move. Two second scissor levers 402 are provided and are symmetrically arranged;

[0064] Scissor lever hinge shaft 403, scissor lever 1 401 and scissor lever 2 402 are connected via the scissor lever hinge shaft 403;

[0065] The scissor lever rear link 407 is connected to the scissor lever 1 401 . The scissor lever rear link 407 connects the two scissor levers 1 401 so that the two scissor levers 1 401 move synchronously.

[0066] The rear lower hinge shaft 408, one end of the scissor lever 2 402 close to the backrest frame 1 is connected to the rear lower hinge shaft 408, and the rear lower hinge shaft 408 is connected to the base plate 7 through the bracket 3.

[0067] When the seat is in shock absorption operation, the scissor rod 1 401 drives the third slider 406 to slide in the front lower rail 10. At the same time, the scissor rod 1 401 drives the first slider 404 to slide in the rear upper rail 8. The scissor rod 2 402 drives the second slider 405 to slide in the front upper 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 side, the up and down movement of the seat is converted into the forward and backward sliding of the sliders.

[0068] The seat is provided with a shock-absorbing assembly 4 to provide shock absorption. By sliding the first and third sliders 404 and 406 on the front side and the second slider 405 on the rear upper side, and driven by the scissor lever rear link 407, the first, second, and third sliders 404, 405, 406 on both sides move together, converting the up and down movement of the seat into forward and backward sliding of the sliders, thereby providing shock absorption within a limited space.

[0069] The locking assembly 5 further includes:

[0070] The slide rail operating rod 505 is connected to the slide rail handle 501 and the slide rail operating rod 505 is connected to the rotation locking plate 503;

[0071] The slide rail linkage rod 502 is connected to the rotation locking plate 503 and is used to link the left and right slide rails so that the left and right slide rails are unlocked and locked synchronously.

[0072] The slide rail locking return spring 504 is installed outside the rotation locking piece 503 .

[0073] 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 rotation locking plate 503 to rotate, and the tooth-like protrusion on the rotation locking plate 503 rotates out from the hole on the slide rail, thereby unlocking the slide rail function on the upper rear side of the seat. At this time, the slide rail lock return spring 504 is deformed.

[0074] Then the slide rail locking return spring 504 gradually returns to its original state, causing the rotation locking piece 503 to rotate back to its original position. The tooth-like protrusions on the rotation locking piece 503 enter the holes of the rear upper slide rail 8, and the slide rail is locked.

[0075] The locking assembly 5 is provided to control the opening or closing of the rear upper slide rail 8. By manually rotating the slide rail handle 501, the tooth-like protrusion on the rotating locking plate 503 is controlled to rotate out of the hole in the slide rail, thereby unlocking the slide rail function on the rear upper side of the seat. At this time, the rear upper slide rail 8 is in the open state, and the slide rail lock return spring 504 is deformed; then the slide rail lock return spring 504 gradually returns to its original state, causing the rotating locking plate 503 to rotate back to its original position, and the tooth-like protrusion on the rotating locking plate 503 enters the hole in the rear upper slide rail 8, locking the slide rail, and now the rear upper slide rail 8 is in the closed state.

[0076] The weight adjustment component 6 includes:

[0077] The weight lower adjustment block 601 has a fixing bolt 614 disposed inside and a step disposed outside the weight lower adjustment block 601;

[0078] The upper weight adjustment block 602 is arranged above the lower weight adjustment block 601, and a wedge-shaped structure is provided between the lower weight adjustment block 601 and the upper weight adjustment block 602;

[0079] The bottom fixing nut 615 is installed at the bottom of the base plate 7. The bottom fixing nut 615 is adapted to the fixing bolt 614. Before using the device, manually adjust the height of the engagement between the fixing bolt 614 and the nut to limit the upward movement limit of the seat.

[0080] The weight adjustment handle 610 is connected to the weight adjustment screw 11;

[0081] An adjusting nut 603 is provided on the outside of the weight adjusting screw 11 , a protrusion 608 is provided on the top of the adjusting nut 603 , and a center block 611 is installed on the outside of the adjusting nut 603 ;

[0082] Two adjusting curved rods 612 are provided. The two adjusting curved rods 612 are respectively installed on the top and bottom of the central block 611. Washers 613 are installed on the outside of the adjusting curved rods 612. The washers 613 are set to a rubber material and are used to protect the protrusions 608.

[0083] Crank 604, which is mounted on the outside of the adjusting nut 603, and a crank rotating shaft 605 is mounted inside the crank 604;

[0084] The crank connecting shaft 606 is arranged inside the crank 604.

[0085] A guide piece 607 is mounted on the outside of the crank connecting shaft 606, and a through groove is formed inside the guide piece 607;

[0086] The tower spring 609 has a smaller diameter side that contacts the weight adjustment block 601 , and a larger diameter side that contacts the bottom plate 7 . The tower spring 609 plays a buffering role during the up and down movement.

[0087] When the driver manually adjusts the weight adjustment handle 610, the weight adjustment handle 610 drives the weight adjustment screw 11 to rotate, causing the adjustment nut 603 on the weight adjustment screw 11 to move forward and backward, and the protrusion 608 on the adjustment nut 603 contacts the washer 613. During the movement of the adjustment nut 603, the washer 613 contacts and drives the crank 604 to rotate around the crank rotation axis 605, and the crank connecting shaft 606 drives the guide plate 607 to move, and the guide plate 607 drives the upper weight adjustment block 602 to move. The wedge structure on the upper weight adjustment block 602 converts the forward and backward movement into the up and down movement of the lower weight adjustment block 601, thereby adjusting the initial compression of the tower spring 609, and then adjusting the initial stiffness of the tower spring 609 to achieve the function of weight adjustment.

[0088] The weight adjustment assembly 6 allows for weight adjustment of the seat. The seat's maximum upward movement is limited by manually adjusting the height of the engagement between the fixing bolt 614 and the nut. The weight adjustment handle 610 is manually adjusted to control the forward and backward movement of the adjustment nut 603. As the adjustment nut 603 moves, the washer 613 contacts and drives the crank 604 to rotate about the crank rotation axis 605. The crank connecting shaft 606 drives the guide plate 607, which in turn drives the upper weight adjustment block 602. The wedge-shaped structure on the upper weight adjustment block 602 converts the forward and backward movement into the up and down movement of the lower weight adjustment block 601, thereby adjusting the initial compression of the tower spring 609 and, in turn, the initial stiffness of the tower spring 609, achieving the weight adjustment function. Furthermore, the washer 613 reduces friction between the protrusion 608 and the guide plate 607, while also reducing the noise generated when the protrusion 608 and the guide plate 607 contact each other.

[0089] Working principle: Before use, manually rotate the slide rail handle 501, which drives the slide rail operating rod 505 to rotate, and the slide rail operating rod 505 drives the rotation locking plate 503 to rotate. The tooth-like protrusion on the rotation locking plate 503 rotates out from the hole on the slide rail, thereby unlocking the slide rail function on the upper rear side of the seat. At this time, the slide rail lock return spring 504 is deformed.

[0090] Before using the device, manually adjust the height of the engagement between the fixing bolt 614 and the nut to limit the seat's upward movement limit. When the driver manually adjusts the weight adjustment handle 610, the weight adjustment handle 610 drives the weight adjustment screw 11 to rotate, causing the adjustment nut 603 on the weight adjustment screw 11 to move back and forth. The protrusion 608 on the adjustment nut 603 contacts the washer 613. During the movement of the adjustment nut 603, the washer 613 contacts and drives the crank 604 to rotate around the crank rotation axis 605. The crank connecting shaft 606 drives the guide plate 607 to move, and the guide plate 607 drives the upper weight adjustment block 602 to move. The wedge 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 of the tower spring 609 and then adjusting the initial stiffness of the tower spring 609 to achieve the weight adjustment function.

[0091] When the seat is in shock absorption operation, the scissor rod 1 401 drives the third slider 406 to slide in the front lower slide rail 10. At the same time, the scissor rod 1 401 drives the first slider 404 to slide in the rear upper slide rail 8. The scissor rod 2 402 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 side, the up and down movement of the seat is converted into the forward and backward sliding of the sliders. At this time, the cushion frame 2 and the bottom plate 7 move forward and backward relative to each other, which plays a sliding function.

[0092] Then the slide rail locking return spring 504 gradually returns to its original state, causing the rotation locking piece 503 to rotate back to its original position. The tooth-like protrusions on the rotation locking piece 503 enter the holes of the rear upper slide rail 8, and the slide rail is locked.

[0093] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
