In summary, the preferred embodiment of the present invention provides a seat that compares to the prior art:

(1) The existing seat power drive mechanism 50 requires an output torque greater than the seat weight torque to rotate the rotating seat; the auxiliary device 60 and the electric driving mechanism 50 of the invention work together to greatly reduce the output torque of the electric driving mechanism 50, so that the electric driving mechanism 50 can be smaller in power and size, and has obvious advantages in terms of structural volume, structural cost and energy consumption.

(2) With the seat of the present invention, the volume of the electric drive mechanism 50 is reduced, so that the electric drive has enough space for solving the problem of self-locking, and when the power supply or the line fails, the person can manually rotate the seat as it is, so that it can be rotated to a desired position state.

The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
