Wherein, the inclination angle of the seat frame has a large influence on the stress distribution of all parts of the body of the rider, and the adjustment of the inclination angle of the seat frame is often called zero gravity adjustment. In earlier developed techniques, zero-gravity adjustment of the seat was generally achieved by means of the following structure: the rear part of the seat frame is rotatably supported above the base, a rotation adjusting mechanism is arranged between the front part of the seat frame and the base, and the rotation adjusting mechanism is driven by a driving motor to drive the seat frame to rotate around a rear cross rod of the seat frame, so that the inclination angle of the seat frame is adjusted. In the earlier developed technology, a rotation adjusting mechanism is generally based on a connecting rod mechanism, one of the connecting rods is driven to rotate through a gear rack mechanism, or one of the connecting rods is replaced by a lead screw nut mechanism, and the rotation adjustment of a seat frame is realized by changing the length of the connecting rod. The main problems existing in the prior art are that the structure of the rotation adjusting mechanism is relatively complex, the number of parts is large, the requirements on processing and assembly are high, and the assembly is time-consuming. In addition, for cost and control reasons, the previous solutions have provided only one drive motor, close to one side of the seat frame, which acts as a holding member for supporting and locking the angle of the seat frame. The seat frame part at the side of the motor can be kept stable well, but the seat frame part far away from the motor has small range of motion relatively, particularly the seat frame has large inclination angle, and the center of gravity of a passenger is close to the rear part of the seat frame. This small degree of motion may affect ride comfort, and for this problem, the existing rotation adjustment mechanism only increases the number of motors to solve, but causes cost increase and more complicated control.
