Each push rod that can pivot up and down about described arc support plate is provided with, the rear end of two push rods and arc support plate articulate respectively, and the front end of two push rods respectively is provided with a roller that rotates;
Along all from rear to before being inclined upwardly, consist of the roller guide part of bogie side frame on the front portion of each bogie side frame;
The bottom wheel face of described two rollers props up respectively the roller guide part of two bogie side frames, and the top wheel face of two rollers props up respectively carriage.
Further, described main backstop is provided with an arc plate and drives linear electric motors, and the power arm that described arc plate drives linear electric motors stretches out towards the rear, and articulates with the arc support plate.
Further, be equipped with arc integrated circuit board groove and arc panel guide for arc support plate slide-and-guide on described two bogie side frames;
The edge, the left and right sides of described arc support plate stretches into respectively in two arc integrated circuit board grooves on the bogie side frame, and the bottom, the left and right sides of arc support plate is with the wedging respectively of the arc panel guide on the mode of being slidingly connected and two bogie side frames.
The guide tracked compensation dentistry electrically propelled chair that this utility model provides, before and after the arc support plate in the arc line shaped sliding process, utilizing push rod to drive carriage pivots up and down, therefore in regulating the back gradient process, the height of medicated cushion is synchronization control thereupon, can guarantee the relatively stable of spacing between backrest and the patient's buttocks position, can avoid backrest in regulating the gradient process, to pull garment for patient, can increase patient's comfortableness.
