As shown in FIG. 2 , the flipping mechanism is two sets of identical structures with left and right symmetry, and one side includes two U-shaped supports 7 , a seat plate 8 , three hinged supports 9 , a flipping electric push rod 10 , and a sub-beam 11 2. Fold the electric push rod 12; two U-shaped supports 7 are respectively fixed on the stepped surface at the bottom end of the main beam 4 of the auxiliary lifting mechanism, and one U-shaped support 7 is hinged to the auxiliary beam 11. The hinged support 9, the hinged support 9 on the upper side of the sub-beam 11 is hinged to the flipping electric push rod 10, the other end of the flipping electric push rod 10 is hinged with the hinged support 9 at the rear end of the seat plate 8, and the front end of the seat plate 8 is hinged with the sub-beam 11 , the hinged support 9 on the lower side of the sub-beam 11 is hinged to the folding electric push rod 12, and the folding electric push rod 12 is hinged with another U-shaped support 7; , to realize the assisting process of going to the toilet; the folding electric push rod 12 telescopically controls the sub-beam 11 to realize the unfolded or folded state of the flipping mechanism; the middle of the seat plate 8 is a through hole, the aperture size is equivalent to the toilet entrance, and the upper surface of the seat plate 8 is wrapped Soft material shaped with female hips.

The working process of the present invention:

First, manually put the armrest 5 from the vertical state to the horizontal state. Then, open the control button at the front end of the armrest 5 to start the folding electric push rod 12 to stretch and push the sub-beam 11 to turn over to a horizontal state, and start the turning electric push rod 10 to stretch and push the seat plate 8 to turn upward at a certain angle to reach the limit position. The organization is in an expanded state. Next, open the control button at the front end of the handrail 5 to start the stepping motor 13 to rotate forward through the coupling 14 and transmit it to the lead screw 2. The control nut 17 descends vertically along the guide rail 15, and the beam 3 connected with the nut 17 drives the entire overturning mechanism to descend synchronously. The plate 8 is lowered to the mid-limit position, ie it corresponds to the height of the human body's buttocks. Finally, the user takes off his clothes, rests his buttocks on the upper surface of the seat plate 8, his arms firmly grasp the armrest 5, and continues to control the forward rotation of the stepping motor 13 and the retraction of the electric push rod 10, so as to keep the seat plate 8 tilted when it vertically descends. The angle becomes smaller and smaller, and when the seat plate 8 is lowered to the upper surface of the toilet, it is also in the horizontal position, which is the lower limit position at this time, and the user starts to defecate. The device completes the assisting process from standing to squatting for supporting the human body during the process from the middle limit position to the lower limit position. After going to the toilet, control the front control button of the armrest 5 to turn on the stepping motor 13 to reverse and turn the electric push rod 10 to extend. Rise, drive the seat plate 8 to rise to the middle limit position, and at the same time the seat plate 8 is also pushed by the flip electric push rod 10 to gradually tilt, the synchronous rise and tilt of the seat plate 8 supports and assists the human body buttocks, and completes the movement from squatting to sitting. Get up and assist the process until the body is in a standing position. At this time, the human body moves forward from the seat plate 8, and after putting on the clothes, the arm completely releases the armrest 5, and continues to control the retraction of the flip electric push rod 10 to drive the seat plate 8 to a horizontal position. Then control the folding electric push rod 12 to shrink, drive the sub-beam 11 to swing down to the vertical direction, and fold the overturning mechanism. Start the stepping motor 13 again to reverse the rotation, so that the turning mechanism carried by the main beam 4 vertically rises along the lead screw 2 to the upper limit position, that is, above the toilet tank, and manually lift the handrail 5 to the vertical state.

The working principle of the present invention:

An automatic auxiliary power assist device for a toilet. The auxiliary lifting mechanism adopts a lead screw and nut mechanism to convert circular motion into linear motion. The relationship is transformed into linear motion, which controls the rise and fall of the beam 3, the main beam 4, the sub-beam 11, and the overturning mechanism. The folding function of the overturning mechanism is controlled by the principle of electric push rod. The folding function of the sub-beam 11 realizes the switching of the sub-beam 11 and its upper bearing assembly in a horizontal or vertical state through the expansion and contraction of the folding electric push rod 12 .
