The lifting mechanism includes left and right electric push rods 4 and 4', left and right active connecting rods 6 and 6' for lifting the lid ring 2, and left and right driven connecting rods 7 and 7' for lifting the seat plate 3. Electric push rods 4 and 4' are telescopically mounted in their respective left and right brackets 10 and 10'. The rear of the left and right electric push rods 4 and 4' is fixed to the bottom of the corresponding left and right brackets 10 and 10'. The lower ends of the left and right active connecting rods 6 and 6' are slidably mounted on the base plate 1. The upper ends of the left and right active connecting rods 6 and 6' are hinged to the movable front ends of the left and right electric push rods 4 and 4'. The lower ends of the left and right driven connecting rods 7 and 7' are hinged to the base plate 1. The upper ends of the left and right driven connecting rods 7 and 7' pass through the cover ring 2 and are hinged to the bottom of the seat plate 3.

[0022] The specific structure is as follows: Left and right electric push rods 4 and 4' are symmetrically arranged in two sets, positioned at the bottom left and right of the cover ring 2. Active and driven connecting rods are also arranged in two sets corresponding to the electric push rods. Below the bottom of the cover ring 2, between the left and right supports 10 and 10', a coaxial motor 5 is provided to drive the synchronous extension and retraction of the two electric push rods. The two ends of the coaxial motor 5 are connected to the left and right electric push rods 4 and 4' respectively. The main body of the left and right supports 10 and 10' is a frame with an inverted U-shaped cross-section, allowing the left and right electric push rods 4 and 4' to be housed within the frame. A single plate extends from the front as a connecting part, hinged to the front end of the base plate 1. The left and right active connecting rods 6 and 6' are L-shaped, with rollers 61 at their rear ends. Guide rails 8 that cooperate with the rollers are provided on the left and right sides of the upper surface of the base plate 1, and upward-facing vertical plates 81 are provided on the outer sides of the guide rails 8. To further improve the smoothness and stability of the left and right active linkages 6 and 6', they are typically designed as separate linkages, consisting of left and right linkages 62. Each linkage 62 has a roller 61 mounted on the opposite side of its bottom rear end. Correspondingly, each guide rail 8 has a guide member 82 between the left and right linkages 62. The left and right sides of the guide member 82 are respectively rails 83 that cooperate with the rollers. The guide member 82 has guide holes 84 arranged in the front and back directions, through which guide shafts pass and are connected to the rollers 61 on each linkage 62. The upper ends of the left and right linkages 62 are hinged to the movable front end of their respective electric push rods. The left and right active linkages 6 and 6' are connected at the bending points by a connecting shaft 30 and their respective left and right brackets 10 and 10'. The left and right driven links 7 and 7' are folding structures formed by hinged upper driven link 72 and lower driven link 71. The lower end of the lower driven link 71 is hinged to the rear end of the vertical plate 81, and the upper end of the upper driven link 72 passes through the cover ring 2 and is hinged to the bottom of the base plate 3. The lower surface of the base plate 3 has mounting seats 9 on the left and right sides of the middle part, which are hinged to the upper ends of the left and right driven links 7 and 7', respectively. Rollers are provided in the mounting seats 9. Correspondingly, the middle left and right sides of the cover ring 2 are respectively formed with strip-shaped slots 21 for the upper driven link 72 to pass through and swing back and forth. The front end of the strip-shaped slots 21 has a limiting groove 22 that cooperates with the roller. The upper part of the left and right upper driven link 72 is provided with connecting pins 20, and the upper part of the side of the left and right brackets 10 and 10' is provided with corresponding connecting holes. The upper part of the upper driven link 72 is axially connected to its respective bracket through the connecting pins 20.

[0023] The working principle is as follows:

[0024] When the electric push rod 4 retracts, it pulls the left and right active connecting rods 6 and 6' to swing upwards around the rollers and move forward along the guide rail 8. Since the active connecting rods are arranged in the bracket, and the bracket is set under the cover ring 2, and the front part of the bracket and the base plate 1 are hinged together, the rear part of the cover ring 2 is lifted, which in turn drives the left and right driven connecting rods 7 and 7' to unfold and lift up. This causes the rollers in the mounting seats 9 of the driven connecting rods 7 and 7' to climb out of the limiting groove 22 and continuously lift up, thereby lifting the seat plate 3. The tilt angle of the seat plate 3 changes with the height. This can prevent the seat plate 3 from tilting too much and causing people to slip, while also preventing the seat plate 3 from being too flat and losing its power assist effect.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
