[0032] The following refers to Figures 1 - 3 Describe the seat assembly according to the embodiment of the present utility model. It has a simple structure, low setting cost, can reduce the gap between the flared section 63 and the side plate 21, avoid the shaking of the seat body 2, improve the riding comfort, and ensure the riding experience.

[0033] As Figures 1 - 3 As shown, a seat assembly according to an embodiment of the present utility model includes: a mounting base 1, a seat body 2, a height adjustment device, and a gap adjustment member 5.

[0034] The seat body 2 is mounted on the mounting base 1. The seat body 2 is provided with a side plate 21. The height adjustment device includes an adjustment toothed plate 3. One end of the adjustment toothed plate 3 is rotatably connected to the side plate 21 through a linkage tube 6. When the adjustment toothed plate 3 rotates relative to the mounting base 1, it drives the side plate 21 and the seat body 2 to lift through the linkage tube 6. The outer peripheral wall of the linkage tube 6 is provided with a first limiting convex portion 61, and a flared section 63 is formed at the end of the linkage tube 6. The gap adjustment member 5 and the side plate 21 are sleeved outside the linkage tube 6 and are limited and pressed between the flared section 63 and the first limiting convex portion 61.

[0035] Among them, the seat assembly is provided with a seat backrest and a seat cushion. The seat backrest and the seat cushion are rotatably connected. The seat cushion is located below the seat backrest. An occupant can sit above the seat cushion and lean on the seat backrest. The seat backrest can be adjusted in angle according to the usage habits of the occupant. And a height adjustment device is provided at the seat cushion. The height adjustment device can adjust the height of the seat assembly, so that the occupant and the like can adjust the height of the seat assembly according to their own conditions and habits, so as to achieve a comfortable sitting posture, meet the different needs of the occupant, and improve the comfort and riding experience.

[0036] Specifically, the seat assembly is provided with a mounting base 1 and a seat body 2. The mounting base 1 can be connected to the vehicle body floor, and the seat body 2 is mounted above the mounting base 1, so that the seat body 2 can be connected to the vehicle body floor. The seat body 2 is provided with side plates 21. The side plates 21 are arranged below the seat body 2 and can extend along the front-rear direction. The side plates 21 are made of metal. And the seat assembly is further provided with a height adjustment device. The height adjustment device can adjust the height of the seat body 2, so as to meet the different riding needs of the occupant. The height adjustment device is provided with an adjustment toothed plate 3 and an adjustment motor 4. The adjustment motor 4 is mounted on the side plate 21 and is power-connected to the adjustment toothed plate 3. One end of the adjustment toothed plate 3 is rotatably connected to the side plate 21 through a linkage tube 6. The linkage tube 6 is provided with two second limiting protrusions 62, which can axially limit the adjustment toothed plate 3 to ensure the installation reliability. And the other end of the adjustment toothed plate 3 is rotatably connected to the mounting base 1. When the adjustment motor 4 drives the adjustment toothed plate 3 to rotate, the adjustment toothed plate 3 can drive the linkage tube 6 and the side plate 21 to move up and down, so that the seat body 2 can move up and down to realize the adjustment of the height of the seat assembly.

[0037] Furthermore, the linkage tube 6 extends along the left-right direction, and the outer peripheral wall of the linkage tube 6 is provided with a first limiting protrusion 61. The first limiting protrusion 61 can be set as an annular protrusion, or can be set as semi-circular protrusions spaced apart along the outer peripheral wall of the linkage tube 6, etc. The linkage tube 6 can pass through the side plate 21, and the end of the linkage tube 6 extends to the outside of the side plate 21. The end of the linkage tube 6 is formed with a flared section 63. The radial dimension of the flared section 63 is set to be larger than the radial dimension of other parts of the linkage tube 6, and the whole of the linkage tube 6 can be set as a straight tube. After the assembly is completed, the end of the linkage tube 6 can be subjected to tube expanding treatment, so that the end of the linkage tube 6 forms a flared section 63.

[0038] Moreover, the seat assembly is further provided with a clearance adjusting member 5, which can be set as a gasket or the like. The side plate 21 can be sleeved outside the linkage pipe 6, and the clearance adjusting member 5 can also be sleeved outside the linkage pipe 6. The clearance adjusting member 5 is located outside the side plate 21 and inside the flared section 63, so that the clearance adjusting member 5 can be limited and pressed between the flared section 63 and the first limiting protrusion 61. Further, the flared section 63 can be pressed against the outer side wall of the clearance adjusting member 5, and the side plate 21 can be pressed against the inner side wall of the clearance adjusting member 5 to reduce the clearance between the flared section 63 and the side plate 21, avoid the shaking of the seat body 2, and then improve the riding comfort and ensure the riding experience. In addition, the clearance adjusting member 5 has a simple structure and a low setting cost. When the linkage pipe 6 is subjected to tube expanding treatment, the first limiting protrusion 61 can provide axial support for the side plate 21, avoid the deformation of the side plate 21 and other situations, affect the installation stability of the seat body 2, and ensure the riding experience.

[0039] According to the seat assembly of the embodiment of the present invention, a clearance adjusting member 5 is provided between the flared section 63 of the linkage pipe 6 and the side plate 21, which can reduce the clearance between the flared section 63 and the side plate 21, avoid the shaking of the seat body 2, and then improve the riding comfort and ensure the riding experience. In addition, the clearance adjusting member 5 has a simple structure and a low setting cost, better use effect and wider application range.

[0040] In some embodiments, the clearance adjusting member 5 is configured as a gasket, and the thickness of the gasket is set as L, and satisfies: 4mm ≤ L ≤ 6mm.

[0041] Specifically, the clearance adjusting member 5 is sleeved outside the linkage pipe 6, and the clearance adjusting member 5 is located outside the side plate 21 and inside the flared section 63. The clearance adjusting member 5 can be set as a gasket, and the gasket can be made of B340LA material, that is, the gasket can be set as low-temperature alloy steel. The mechanical properties such as the tensile strength, yield point and elongation of B340LA are very excellent, and it has good low-temperature toughness and corrosion resistance, which can ensure the service life and reduce the later maintenance cost. The thickness of the gasket can be set as L, and the thickness L of the gasket is set to satisfy: 4mm ≤ L ≤ 6mm, that is, the thickness L of the gasket can be set as 4mm, 5mm or 6mm, etc. In this embodiment, the thickness L of the gasket can be set as 5mm. Setting the thickness L of the gasket to satisfy 4mm ≤ L ≤ 6mm can ensure the reliability of the gasket being limited and pressed between the flared section 63 and the first limiting protrusion 61, so that the flared section 63, the gasket and the side plate 21 are closely attached in sequence, avoid the shaking of the seat body 2, improve the riding comfort, and then ensure the riding experience.

[0042] In some embodiments, the outer diameter of the flared section 63 is set to gradually decrease along the direction close to the clearance adjusting member 5.

[0043] Specifically, the end of the linkage pipe 6 extends to the outside of the side plate 21, and after assembly, the end of the linkage pipe 6 can be subjected to tube expanding treatment, so that a flared section 63 is formed at the end of the linkage pipe 6. The radial dimension of the flared section 63 is set to be larger than the radial dimension of other parts of the linkage pipe 6, and as Figure 1 shown, the outer diameter of the flared section 63 is set to gradually decrease in the direction close to the gap adjusting member 5, that is, the radial dimension of the end of the flared section 63 close to the gap adjusting member 5 is set to be the smallest, and the radial dimension of the end of the flared section 63 far from the gap adjusting member 5 is set to be the largest. That is, the outer peripheral wall of the flared section 63 is set to a flared structure, and the opening is axially open outward. The gap adjusting member 5 is sleeved outside the linkage pipe 6 and is located between the flared section 63 and the side plate 21. Setting the outer diameter of the flared section 63 to gradually decrease in the direction close to the gap adjusting member 5 can prevent the gap adjusting member 5 from coming off the linkage pipe 6, and enables the flared section 63 to gradually apply a pressing force to the outside of the gap adjusting member 5, ensuring the reliability of use of the gap adjusting member 5.

[0044] In some embodiments, the maximum outer diameter of the flared section 63 is larger than the inner diameter of the gap adjusting member 5, and the outer diameter of the gap adjusting member 5 is larger than the maximum outer diameter of the flared section 63.

[0045] Specifically, the flared section 63 is arranged at the end of the linkage pipe 6, the gap adjusting member 5 can be pressed between the flared section 63 and the side plate 21, and the outer diameter of the flared section 63 is set to gradually decrease in the direction close to the gap adjusting member 5, and as Figure 1 shown, the maximum outer diameter of the flared section 63 is larger than the inner diameter of the gap adjusting member 5. The maximum outer diameter of the flared section 63 is located at the end of the flared section 63 far from the gap adjusting member 5. The maximum outer diameter of the flared section 63 is set to be larger than the inner diameter of the gap adjusting member 5, so as to prevent the gap adjusting member 5 from coming out of the flared section 63, ensuring the reliability of the installation of the gap adjusting member 5. And setting the maximum outer diameter of the flared section 63 to be larger than the inner diameter of the gap adjusting member 5 enables at least part of the flared section 63 to apply a pressing force to the gap adjusting member 5, ensuring that the gap adjusting member 5 can be pressed between the flared section 63 and the side plate 21, preventing the seat body 2 from shaking, and ensuring the riding comfort.

[0046] Furthermore, the outer diameter of the gap adjusting member 5 is set to be larger than the maximum outer diameter of the flared section 63. The maximum outer diameter of the flared section 63 is located at the end of the flared section 63 far from the gap adjusting member 5. Setting the outer diameter of the gap adjusting member 5 to be larger than the maximum outer diameter of the flared section 63 enables the flared section 63 to reach the limit position during tube expanding treatment, that is, when the flared section 63 extends radially, the flared section 63 can be pressed against the gap adjusting member 5, ensuring that the pressing force can act on the gap adjusting member 5 and ensuring the reliability of pressing on the gap adjusting member 5.

[0047] In some embodiments, the first limiting convex portion 61 is configured as an annular protrusion, and the side plate 21 is formed with a through hole 22 for passing through the linkage pipe 6.

[0048] Specifically, the outer peripheral wall of the linkage pipe 6 is provided with a first limiting convex portion 61, and the gap adjusting member 5 can be limited and pressed between the flared section 63 and the first limiting convex portion 61, and as Figure 1 shown, the first limiting convex portion 61 is configured as an annular protrusion, that is, the annular protrusion is located on the outer peripheral wall of the linkage pipe 6 and protrudes radially outward. The annular protrusion is located inside the side plate 21, and the side plate 21 is provided with a through hole 22. The linkage pipe 6 can extend into the through hole 22 so that the end of the linkage pipe 6 is located outside the side plate 21. The flared section 63 is formed at the end of the linkage pipe 6, that is, the flared section 63 and the annular protrusion are respectively located on both sides of the side plate 21. The gap adjusting member 5 is arranged between the flared section 63 and the side plate 21, that is, both the gap adjusting member 5 and the side plate 21 are located between the flared section 63 and the annular protrusion. When the flared section 63 is subjected to tube expanding treatment, a pressing force can be applied to the gap adjusting member 5, so that the gap adjusting member 5 and the side plate 21 are closely attached, and the annular protrusion can limit and support the side plate 21, avoiding displacement of the linkage pipe 6 and deformation of the side plate 21, etc., and ensuring the assembly reliability.

[0049] Wherein, the inner diameter of the gap adjusting member 5 is smaller than the maximum outer diameter of the flared section 63 and smaller than the outer diameter of the annular protrusion. The inner diameter of the through hole 22 is smaller than the maximum outer diameter of the flared section 63 and smaller than the outer diameter of the annular protrusion. As Figure 1 shown, the maximum outer diameter of the flared section 63 is located at the end of the flared section 63 away from the gap adjusting member 5. The maximum outer diameter of the flared section 63 is set to be larger than the inner diameter of the gap adjusting member 5, so as to avoid the gap adjusting member 5 coming out of the flared section 63 and ensure the reliability of the installation of the gap adjusting member 5. And the inner diameter of the gap adjusting member 5 is set to be smaller than the outer diameter of the annular protrusion, so that when the flared section 63 applies a pressing force to the gap adjusting member 5, the pressing force can also be conducted axially to the annular protrusion. And the inner diameter of the through hole 22 is smaller than the maximum outer diameter of the flared section 63 and smaller than the outer diameter of the annular protrusion, so that the flared section 63, the gap adjusting member 5, the side plate 21 and the annular protrusion all have partial correspondence axially, avoiding deformation of the side plate 21 and prolonging the service life.

[0050] In some embodiments, the maximum outer diameter of the flared section 63 is smaller than the outer diameter of the annular protrusion, as Figure 1As shown, the maximum outer diameter of the flared section 63 is located at one end of the flared section 63 away from the gap adjusting member 5. The larger the maximum outer diameter of the flared section 63, the larger the area corresponding to the gap adjusting member 5 in the axial direction, and thus the greater the pressing force exerted on the gap adjusting member 5. The larger the outer diameter of the annular protrusion is set, the larger the contact area between the annular protrusion and the side plate 21, and thus the greater the pressing force exerted on the side plate 21. By making the maximum outer diameter of the flared section 63 smaller than the outer diameter of the annular protrusion, it is possible to avoid excessive pressing force exerted by the flared section 63 on the gap adjusting member 5, which may cause deformation of the side plate 21 and the annular protrusion, and ensure the reliability of the limit.

[0051] In some embodiments, the seat assembly further includes a bushing 7. The bushing 7 is installed on the side plate 21 and sleeved outside the linkage tube 6, and the bushing 7 separates the side plate 21 from the linkage tube 6.

[0052] Specifically, as Figure 1 shown, the seat assembly is further provided with a bushing 7. The bushing 7 can be set as an annular structure. The bushing 7 is sleeved outside the linkage tube 6 and installed at the through hole 22 of the side plate 21, so as to separate the side plate 21 from the linkage tube 6. The bushing 7 can be set as a metal part, etc. When the height adjusting device operates, the adjusting tooth plate 3 can drive the linkage tube 6 to rotate relative to the side plate 21. By providing the bushing 7 between the side plate 21 and the linkage tube 6, the bushing 7 can support between the side plate 21 and the linkage tube 6. And when the linkage tube 6 rotates relative to the side plate 21, the through hole 22 of the side plate 21 can act on the bushing 7, avoiding wear of the linkage tube 6, extending the service life, and lubricating between the side plate 21 and the linkage tube 6, ensuring smooth operation and improving the user experience.

[0053] In some embodiments, the bushing 7 includes a connecting section 71 and two pressing sections 72. The two pressing sections 72 are connected to both ends of the connecting section 71 and are radially separated from each other on the radial outer side of the connecting section 71. The connecting section 71 is located between the linkage tube 6 and the side plate 21. One of the two pressing sections 72 is located between the gap adjusting member 5 and the side plate 21, and the other of the two pressing sections 72 is located between the side plate 21 and the first limiting protrusion 61.

[0054] Specifically, a bushing 7 is provided between the side plate 21 and the linkage tube 6. And as Figure 1 shown, the bushing 7 is provided with a connecting section 71 and a pressing section 72. The pressing section 72 is provided with two, and the two pressing sections 72 are both radially extended, that is, the two pressing sections 72 are both annular structures. The connecting section 71 is axially extended, that is, the connecting section 71 is a circular tubular structure. And the two pressing sections 72 are spaced apart and distributed on both sides of the connecting section 71 in the axial direction. The two ends of the connecting section 71 are respectively connected to the inner rings of the two pressing sections 72, so that the connecting section 71 and the two pressing sections 72 are constructed into a "U" - shaped structure and are open radially outwards.

[0055] Further, the connecting section 71 is disposed between the linkage pipe 6 and the side plate 21. That is, the connecting section 71 can support between the side plate 21 and the linkage pipe 6. And when the linkage pipe 6 rotates relative to the side plate 21, the through hole 22 of the side plate 21 can act on the connecting section 71 to prevent the linkage pipe 6 from being worn, extend the service life, and can lubricate between the side plate 21 and the linkage pipe 6. One of the two pressing sections 72 is located between the gap adjusting member 5 and the side plate 21, and thus can support and lubricate between the gap adjusting member 5 and the side plate 21. The other of the two pressing sections 72 is located between the side plate 21 and the first limiting convex portion 61, and thus can support and lubricate between the first limiting convex portion 61 and the side plate 21, ensuring smooth operation and improving the use experience.

[0056] In some embodiments, there are two side plates 21, and the two side plates 21 are respectively located on both sides of the seat body 2. A first limiting convex portion 61 is provided on the outer peripheral wall of the linkage pipe 6 near both ends, and flared sections 63 are formed at both ends of the linkage pipe 6. Among them, there are two gap adjusting members 5, and the two gap adjusting members 5 are distributed between the corresponding flared sections 63 and the first limiting convex portions 61 in one-to-one correspondence with the two side plates 21.

[0057] Specifically, the seat body 2 is provided with side plates 21. The side plates 21 are disposed below the seat body 2 and can extend along the front-rear direction. The side plates 21 can be provided as two, and the two side plates 21 are correspondingly disposed on both sides of the seat body 2. And the two side plates 21 are both provided with through holes 22, and the two through holes 22 are correspondingly disposed in the left-right direction. The linkage pipe 6 can be sequentially passed through the two through holes 22, and both ends of the linkage pipe 6 can extend out of the through holes 22. At the same time, a first limiting convex portion 61 is provided on the outer peripheral wall of the linkage pipe 6 near both ends, so that both of the two first limiting convex portions 61 can be limited and abutted against the inner side of the side plate 21 to ensure the reliability of the installation of the linkage pipe 6.

[0058] Further, both ends of the linkage pipe 6 extend out of the side plate 21, and flared sections 63 are formed at both ends of the linkage pipe 6 extending out of the side plate 21. The gap adjusting members 5 are also provided as two, and the two gap adjusting members 5 are distributed between the corresponding flared sections 63 and the first limiting convex portions 61 in one-to-one correspondence with the two side plates 21, so that gap adjusting members 5 are provided on both sides of the seat body 2. Thus, both of the two side plates 21 can respectively press against the inner side walls of the corresponding gap adjusting members 5 to reduce the gap between the flared sections 63 on both sides of the seat body 2 and the side plates 21, prevent the seat body 2 from shaking, and further improve the riding comfort and ensure the riding experience.
