The state is changed to an actuation control signal corresponding to the actuation of the state of the ride. The power source 150 can provide the corresponding power to the auxiliary lifting mechanism 160 after obtaining the actuation control signal generated by the processing module 130 corresponding to the operation of the seat from the auxiliary standing state to the state of providing the riding state (step 280). The auxiliary lift mechanism 160 moves the seat to wait for the seat assembly 110 of the seat, thereby shifting the seat from the assisted standing state to the state of providing the ride (step 290), thus, the present invention can provide assistance The standing function seat automatically returns to the state of providing the ride after the auxiliary user gets up, and it is no longer necessary for the next user to manually control the state of the seat from the assisted lift to the state of providing the ride.

In the above embodiment, in order to prevent the user who leaves the seat from moving slowly, causing the distance between the user and the seat to be too short, so that the seat is changed from the state of assisting the body to the state of providing the ride, The rider component that assists the movement of the lift-up mechanism collides with the user. Therefore, the process module 130 can determine the buffer time after determining that the sensory signal generated by the sensor module 120 indicates that the user has left the seat (step 271). ), without generating an actuation control signal corresponding to the action of the seat being changed from the assisted standing state to the state in which the seat is provided.

The processing module 130 can also continuously determine whether the calculated buffer time reaches a predetermined value (step 275), such as ten seconds or one minute, while calculating the buffer time. The severance module 130 can generate an actuation control signal corresponding to the actuation of the seat from the state of assisting the standing to the state of providing the occupant after determining that the buffering time reaches a predetermined value. In this manner, the power source 150 can obtain the actuation control signal generated by the processing module 150 to provide the corresponding power to the auxiliary lifting mechanism 160 (step 280), so that the auxiliary lifting mechanism 160 moves the seat to wait for the seat. The assembly 110 is mounted to cause the seat to transition from a state of assisted standing to a state of providing a ride (step 290).

Hereinafter, the operation and method of the present invention will be explained in the second embodiment. Please refer to "Fig. 2" as well. In the present embodiment, it is assumed that the apparatus to which the present invention is applied is a sofa having an assisted lifting function.
