[0004] 1) The A-type plug door of the domestic A company realizes the opening and closing of the door along the x direction, and realizes the plug movement along the y direction to achieve sealing, but the bearing shaft moving along the x direction is not fixed, and it moves along the y direction at the same time , so the stability of the bearing shaft is slightly poor, the structure size is large, and the space occupied is large;
[0005] 2) The B-type plug door of foreign company B can open and close the door along the x direction. The bearing shaft moving in the x direction is fixed and has good rigidity. The rocker mechanism realizes the plugging of the door, and its rigidity is good, but the structural size is large, and the door leaf has a swing up and down when it is used as a plugging rod, which will affect the dynamic stability of the door leaf when it is quickly opened and closed;
[0006] 3) The C-type plug door of foreign C company also realizes the door opening and closing along the x direction, the bearing shaft is fixed, and the plug movement of the door is realized by a four-bar mechanism that rotates around the z axis, and its rigidity is better , but the door leaf must be strengthened along the z-axis direction when it is used as a plug, so that the structural size is larger and the cost is higher

Abstract
The invention discloses a spiral door carrying guide rod groove cam combination space mechanism for a sliding-plug door and relates to a sliding and plug, sealing, opening and closing mechanism for the sliding-plug door of a vehicle, in particular to the spiral door carrying guide rod cam combination space mechanism for the sliding-plug door of high-speed rail or other railway vehicles. The mechanism comprises a motor, a coupler, a screw, a bearing shaft, a coupling rod A, a nut, a coupling rod B, a shaft sleeve, a coupling rod C, a door carrying rod sleeve, a door carrying guide rod, a roller, a roller shaft, a door handle, a groove cam, a door leaf and a door frame, wherein a spiral mechanism consists of the nut, the screw and the door frame; a door carrying guide rod mechanism consists of the nut, the door carrying rod sleeve, and the shaft sleeve which are connected fixedly and integrally through the coupling rod A, the coupling rod B, and the coupling rod C, the bearing shaft, the door carrying guide rod, and the door frame; a groove cam mechanism consists of the door carrying guide rod, the door handle, and the door leaf which are connected fixedly and integrally, and the bearing shaft, the groove cam, the roller shaft, and the roller; and the three mechanisms are connected with one another to form the spiral door carrying guide rod groove cam combination space mechanism for the sliding-plug door.
Description
technical field [0001] The present invention relates to a sliding door screw carrying door guide rod groove type cam combination space mechanism, which relates to a plug sealing opening and closing mechanism of a vehicle sliding door, in particular to a screw carrying sliding door of a high-speed rail or other rail vehicles. The combination space mechanism of the door guide rod groove type cam. Background technique [0002] Rail vehicle plug doors are generally double-leaf or single-leaf. When they are double-leaf, on the one hand, it is necessary to realize the opening and closing movement of the two doors that are opened and closed; The inner door leaf plugging movement is to ensure a good sealing effect after closing the door; when it is a single leaf, the above-mentioned plugging sealing opening and closing movement is also realized, which is only to realize the single opening and single closing of one leaf. [0003] In order to realize the function of opening and closi...
