A seat assembly method as claimed in claim 1, wherein: in the step S2, the method for adjusting the position of the skeleton body to enable the straight line segment of the outer ring of the coil spring to be at the first preassembly position includes: the framework body is turned backwards along the X direction until the framework body is in a vertical state or close to the vertical state, and the rotating shaft rotates along with the framework body to drive the straight line segment of the coil spring to be in a first preassembly position.
4. A seat assembling method according to any one of claims 1 to 3, wherein: the first preassembly position is a position between a Z-direction plane where the axis of the rotating shaft is located and the second preassembly position.
5. A seat assembly method as claimed in claim 1, wherein: in step S2, the method for assembling the skeleton body, the lower bracket and the coil spring, which maintain the assembled state in step S1, to the vehicle body includes: the lower support is directly fastened and fixed on the vehicle body through a bolt structure, and then the assembly work of assembling the framework body, the lower support and the coil spring on the vehicle body can be completed.
6. A seat assembly method as claimed in claim 1, wherein: in step S4, the method for locking the skeleton body includes: locking connection is carried out through this internal locking mechanical system of skeleton and automobile body steel wire, makes the stable support of skeleton body on the lower carriage.
7. A seat assembly method as claimed in claim 1, wherein: in the step S1, the method for assembling the inner ring of the coil spring to the end of the rotating shaft includes: and the inner ring of the coil spring is sleeved on the square mounting column at the end part of the rotating shaft, and the inner ring of the coil spring is fixedly connected with the mounting column in the rotating direction around the axis of the rotating shaft through a compression bolt.
8. A seat assembly method as set forth in claim 2, wherein: the upper end of the lower support is protruded along the Y direction to form a curved plate-shaped structure, the upper end of the curved plate-shaped structure is a limiting table, and the Y direction is an inclined plane towards the outside.
9. A seat assembly method as set forth in claim 8, wherein: and the limiting table is provided with a limiting clamping groove for limiting the Y-direction movement of the straight-line segment.
10. A seat assembly method as set forth in claim 8, wherein: and one end of the limiting table, which is outward along the Y direction, is higher than one end of the limiting table, which is inward along the Y direction.
