    Description

    Field of the Invention



    [0001] The present invention relates to a sliding plug door bearing mechanism, according to the preamble of claim 1. Such a sliding plug bearing mechanism is the key bearing component of sliding plug door, and pertains to the technical field of sliding plug doors.

    Background of the Invention



    [0002] The bearing mechanism directly determines the service life, cost and reliability of sliding plug door. Existing sliding plug doors are mainly based on the following two operating principles (with reference to Patent Application No. CN200420026953.7). One operating principle is that the door leaf translates in X-axis direction and Y-axis direction along a predefined trace to accomplish door leaf sliding (displacement in Y-axis direction). With respect to this operating principle, two bearing guide systems must be arranged in X-axis direction and Y-axis direction. Therefore, the structure is complex, and the manufacturing cost is high. The other operating principle is that the door leaf translates in X-axis direction and swings in the plane (X, Y) to accomplish door leaf sliding (displacement in Y-axis direction). With respect to this operating principle, two bearing guide systems are also required.

    [0003] A sliding plug door bearing mechanism according to the preamble of claim 1 is known from US 2 774 998.

    Summary of the Invention



    [0004] The present invention is characterized by the characterizing part of claim 1 and provides a novel sliding plug door bearing mechanism in order to overcome the drawbacks of existing sliding plug doors. The sliding plug door bearing mechanism provided in the present invention not only has high sealing performance, but also has simple structure, high reliability, reduced requirement for precision of parts, good machinability, and lower manufacturing cost.

    [0005] The technical scheme of the present invention is summarized in that: the sliding plug door bearing mechanism comprises bearing rail, bearing rollers, guiding slide, bearing carriage, door carrying frame, upper connecting shaft, lower connecting shaft, upper hinge holder, lower hinge holder, and guiding wheel, wherein, the bearing carriage, upper connecting shaft, upper hinge holder, and door carrying frame are connected sequentially to form a turning pair I; the door carrying frame, lower connecting shaft, lower hinge holder, and door leaf are connected sequentially to form a turning pair II; the bearing rollers are connected to the bearing rail to form a prismatic pair I; the guiding slide is connected to the guiding wheel to form a prismatic pair II with a non-linear predefined trace; the bearing carriage translates in X-axis direction along the bearing rail, while the door carrying frame drives the door leaf to turn around the X-axis of the bearing carriage; the door carrying frame turns around the X-axis of the bearing carriage while it moves straightly along the bearing rail, and the door carrying frame drives the door leaf to accomplish displacement in Y-axis direction along the non-linear predefined trace of the guiding slide as guided by the guiding wheel.

    [0006] The present invention has the following advantages: the bearing guide mechanism of the door leaf translates in X-axis direction and turns around X-axis to accomplish door leaf sliding in Y-axis direction. The bearing guide mechanism incorporates translation motion and turning motion, and therefore has compact structure, high reliability, reduced requirement for precisions of parts, good machinability, and low manufacturing cost.

    Detailed Description of the Embodiments



    [0009] As shown in Figure 1, the sliding plug door bearing mechanism comprises bearing rail 1, bearing rollers 2, guiding slide 3, bearing carriage 4, door carrying frame 5, upper connecting shaft 6, lower connecting shaft 7, upper hinge holder 8, lower hinge holder 9, and guiding wheel 10, wherein, the bearing carriage 4, upper connecting shaft 6, upper hinge holder 8, and door carrying frame 5 are connected sequentially to form a turning pair I; the door carrying frame 5, lower connecting shaft 7, lower hinge holder 9, and door leaf 12 are connected sequentially to form a turning pair II; the bearing roller 2 is connected to the bearing rail 1 to form a prismatic pair I; the guiding slide 3 is connected to the guiding wheel 10 to form a prismatic pair II with a non-linear predefined trace.

    [0010] An anti-bounce wheel 11 is additionally provided on the bearing carriage 4 to control the moving position of the bearing carriage 4.

    [0011] In operation, the bearing carriage 4 translates along the bearing rail 1 in X-axis direction, while the door carrying frame 5 drives the door leaf 12 to turn around the X-axis of the bearing carriage, so as to accomplish the movement of door leaf in Y-axis direction.

    [0012] The door carrying frame 5 turns around the X-axis of bearing carriage 4 within a certain range while it moves straightly along the bearing rail 1. The door carrying frame 5 drives the door leaf 12 to accomplish the displacement of door leaf in Y-axis direction along the trace of the guiding slide as guided by the guiding wheel.
