AI Technical Summary
Traditional adjustment mechanisms can only accommodate a small range of adjustment, failing to meet the needs for passenger space and comfort.
By setting a parallel first pivot and a power component between the seat back and the vehicle body, the power component drives the connecting component to move closer to and away from the first pivot, allowing the seat back to rotate around the pivot at a large angle. Combined with the limiting bracket and guide groove to limit the position, noise is reduced and smoothness is improved.
It enables a large-angle adjustment of the seat back, reduces the tolerance requirement for the backrest lock, reduces noise, lowers costs, and improves user comfort.

Abstract
Claims
1. An adjustment mechanism, characterized by The adjustment mechanism includes a connecting component, a power component, and a first rotating shaft; The connecting component is used to connect to the seat back, which is rotatably connected to the vehicle body via a backrest pivot. The power assembly is used to rotatably connect to the vehicle body via the first rotating shaft. The first rotating shaft is spaced apart from the backrest rotating shaft, and the axis of the first rotating shaft is parallel to the axis of the backrest rotating shaft. The power assembly is connected to the connecting assembly, and the power assembly is used to drive the connecting assembly to move closer to and away from the first rotating shaft, so that the seat back rotates relative to the vehicle body around the backrest rotating shaft.
2. The adjustment mechanism of claim 1, wherein, The adjustment mechanism further includes a limiting bracket for fixed connection with the vehicle body. The limiting bracket is provided with a first guide groove that extends along a first arc-shaped path around the backrest pivot. At least a portion of the connecting components are slidably disposed within the first guide groove.
3. The adjustment mechanism of claim 2, wherein, The limiting bracket includes a first limiting part for fixed connection with the vehicle body, and a first guide groove is disposed in and passes through the first limiting part; the connecting assembly includes a first connector and a second connector, the first connector for connection with the seat back, the second connector including a first connecting part and a second connecting part connected together, the first connecting part being connected to the first connector, a portion of the first connecting part being slidably disposed in the first guide groove, and the second connecting part and the first connector being disposed on both sides of the first limiting part.
4. The adjustment mechanism of claim 3, wherein, The limiting bracket further includes two second limiting parts, which are located at both ends of the first limiting part and are arranged opposite to each other. The first connecting member is located between the two second limiting parts.
5. The adjustment mechanism of claim 3, wherein, The adjustment mechanism further includes a connecting bracket and a second rotating shaft. The power component is rotatably connected to the connecting bracket via the second rotating shaft, and the connecting bracket is rotatably connected to the vehicle body via the first rotating shaft. The axis of the second rotating shaft is perpendicular to the axis of the backrest rotating shaft. Rotating the power component relative to the connecting bracket around the second rotating shaft can cause the power component to drive the connecting component to move, and cause the second connecting part to move closer to and further away from the first limiting part.
6. The adjusting mechanism according to claim 2, characterized in that, The inner wall of the first guide groove is provided with a first elastic buffer pad, and the connecting component is slidably in contact with the first elastic buffer pad.
7. The adjustment mechanism of claim 2, wherein, The power component is used to rotatably connect to the limiting bracket via the first rotating shaft.
8. The adjustment mechanism of claim 2, wherein, The limiting bracket is provided with a second guide groove, which is located between the first guide groove and the first rotating shaft, and extends along a second arc-shaped path around the first rotating shaft; the power component includes a stop member, at least a portion of which is slidably disposed within the second guide groove.
9. The adjustment mechanism of claim 8, wherein, The inner wall of the second guide groove is provided with a second elastic buffer pad, and the stop member is slidably in contact with the second elastic buffer pad.
10. The adjustment mechanism according to any one of claims 1 to 9, characterized in that The power assembly includes a screw connected to a motor, the connection assembly threadably engages the screw, and the motor is configured to rotate the screw about an axis of the screw to move the connection assembly toward and away from the first swivel axis.
11. A seat assembly characterized by, The seat assembly includes a seat back and the adjustment mechanism of any of claims 1-10.
12. A vehicle, characterized in that, The vehicle includes the seat assembly of claim 11.
