[0002] Among seat configurations and functions, the height adjustment function is relatively common. The realization of the height adjustment function often relies on a four-bar linkage as the basis, and is assisted by a motor driving a gear or a lead screw. When adopting the adjustment method of a driving motor plus a lead screw, the cooperation between the screw rod at the motor output end and the moving nut has a rotational form, and a large rotational torque will be generated at the moment when the motor starts. However, the stability of the motor during the installation process is poor, which is not convenient for the staff to operate.
[0003] The motor mounting structure in the prior art generally forms a mounting frame by cooperating two front and rear horizontal pipes with two side plates, and then connects and mounts the motor through the mounting components in one of the side plates to achieve the fixation of the push rod motor.
