[0024] Figure 1 It shows a schematic structural diagram of a multi-axis linkage chassis with adaptive adjustment in an embodiment of the utility model. Figure 2 The bottom structure schematic diagram of the sliding plate in the embodiment of the utility model is shown. Figure 3 The structure diagram of the fixed base in the embodiment of the utility model is shown. Figure 4 A schematic diagram of the matching structure of the sliding plate and the fixed base in an embodiment of the utility model is shown, the multi-axis linkage guide rail 21 chassis includes a fixed base 2 and a sliding plate 1 slidably matched on the fixed base 2, the fixed base 2 is set on the seat bracket, the sliding plate 1 is used to carry the seat cushion, the sliding plate 1 is slidably matched on the fixed base 2, so that the sliding plate 1 can slide on the fixed base 2, thereby realizing the relative movement of the seat cushion and the seat.

[0025] Specifically, a matching groove 11 is provided on the bottom of the sliding plate 1, and the fixed base 2 is snap-fitted in the matching groove 11. Slide grooves 13 are provided on the inner walls on both sides of the matching groove 11. Guide rails 21 are provided on the side walls on both sides of the fixed base 2. The guide rails 21 of the fixed base 2 slide and cooperate with the slide grooves 13 in the matching grooves 11. The sliding plate 1 is sleeved on the fixed base 2 based on the matching groove 11. An invisible guide rail is provided in the matching groove 11. The invisible guide rail matches the fixed base 2 to improve the matching stability of the sliding plate 1 and the fixed base 2; the slide grooves 13 in the matching grooves 11 are slidably fitted on the guide rails 21 on both sides of the fixed base 2, so that the sliding plate 1 can slide along the guide rails 21, thereby adjusting the relative position state of the sliding plate 1 and the fixed base 2.

[0026] When the sliding plate 1 is moved on the fixed base 2, the tension spring 3 can be stretched and deformed with the relative movement between the sliding plate 1 and the fixed base 2. When the sliding plate 1 and the fixed base 2 are in a non-locked state, the sliding plate 1 can move on the fixed base 2 based on the elastic recovery of the tension spring 3, thereby restoring the initial matching state between the sliding plate 1 and the fixed base 2. The sliding plate 1 and the fixed base 2 are connected based on the tension spring 3, so that when the user adjusts the relative position of the sliding plate 1 and the fixed base 2, the position between the sliding plate 1 and the fixed base 2 can be quickly reset based on the tension spring 3.

[0027] Furthermore, the seat cushion is covered on the surface of the sliding plate 1, which can improve the appearance of the seat. By adjusting the sliding of the sliding plate 1, the horizontal movement of the seat cushion can be adjusted, and the position distance between the seat cushion and the seat back can be adjusted. The user can adjust the relative position of the seat cushion and the seat back according to his or her body shape and sitting habits, thereby improving the user's comfort in using the seat product.

[0028] Specifically, a plurality of locking racks 22 are provided on the guide rails 21 on both sides of the fixed base 2, a locking block 24 and an adjusting block 14 extending outside one side of the fixed base 2 are provided on one side of the fixed base, the adjusting block 14 is connected to the locking block 24 based on a connecting rod, the locking block 24 is engaged with the locking rack 22, so that the sliding plate 1 and the fixed base 2 can be relatively fixed, that is, the locking block 24 is used to control the relative position state between the sliding plate 1 and the fixed base 2, and the matching state of the locking block 24 and the locking rack 22 can be controlled based on the adjusting block 14, so that the locking block 24 and the locking rack 22 are engaged or disengaged.

[0029] Furthermore, the user can press the adjustment block 14 to disengage the locking block 24 from the engagement with the positioning rack 22, thereby pushing the sliding plate 1 to move on the fixed base 2, and adjusting the relative position between the sliding plate 1 and the fixed base 2. When the user completes the relative position adjustment of the sliding plate 1, the user releases the adjustment block 14 so that the locking block 24 can engage with the positioning rack 22, and the relative fixation between the sliding plate 1 and the fixed base 2 is achieved.

[0030] Through the snap-fitting cooperation between the locking block 24 and the locking rack 22, the fixed base 2 and the sliding plate 1 can be locked to avoid misalignment between the fixed base 2 and the sliding plate 1 during normal use, thereby ensuring the reliability of the user when using the seat.

[0031] Specifically, a top block 23 is provided on the top of the fixed base 2, and the top block 23 is connected to the bottom of the sliding plate 1. Based on the top block 23, the fixed base 2 improves the matching rigidity with the sliding plate 1, so that the chassis of the multi-axis linkage guide rail 21 has good supporting performance to meet the user's usage requirements.

[0032] Furthermore, the top block 23 is an arc-shaped protrusion, and the side of the top block 23 connected to the sliding plate 1 is an arc surface. The structural stability of the fixed base 2 is improved based on the arc-shaped protrusion, and two symmetrically distributed top blocks 23 are provided on the fixed base 2. The bearing performance and force stability of the fixed base 2 are improved based on the two top blocks 23, thereby improving the stability of the connection structure of the fixed base 2.

[0033] Furthermore, based on the arc surface structure of the top block 23, the bottom surfaces of the fixed base 2 and the sliding plate 1 are connected based on the contact point, thereby reducing the contact area between the fixed base 2 and the sliding plate 1, thereby reducing the friction between the fixed base 2 and the sliding plate 1, so that the fixed base 2 and the sliding plate 1 can slide conveniently.

[0034] Specifically, a plurality of reinforcing ribs are provided on the sliding plate 1 and the fixed base 2. The fixed base 2 and the sliding plate 1 improve their own structural rigidity based on the plurality of reinforcing ribs, thereby improving the structural support capacity and structural stability of the fixed base 2 and the sliding plate 1 to meet the usage requirements of different users.

[0035] Specifically, the top surface of the sliding plate 1 is recessed inward to form a curved concave structure. Based on the concave structure, the sliding plate 1 can improve the coverage of the user's buttocks, and cooperate with the seat cushion to improve the comfort of the user when using the seat.

[0036] Specifically, a plurality of connecting holes are provided at the bottom of the fixed base 2, and the fixed base 2 is fixedly connected to the seat based on the connecting holes. A support frame is provided at the bottom of the seat, and the support frame is connected to the connecting holes of the fixed base 2 based on bolts, thereby realizing the installation of the fixed base 2 on the seat.
