[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 main axis moving along the x direction is not fixed, it moves along the y direction at the same time, Therefore, the stability of the spindle is slightly poor, the structure size is large, and the space occupied is large;
[0005] 2) The B-type sliding door of foreign company B realizes the opening and closing of the door along the x direction. The main shaft moving in the x direction is fixed and has good rigidity. The rod 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 plug, 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 main 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 good. However, when the door leaf is used as a plug, the support must be strengthened along the z-axis direction, which makes the structural size larger and the cost higher

Abstract
The invention discloses a spiral rocker guide rod composite hinge groove cam combination space mechanism for a sliding-plug door, relates to a sliding and plug, sealing, and opening and closing mechanism for the sliding-plug door for a vehicle, in particular to the spiral rocker guide rod composite hinge groove cam combination space mechanism for the sliding-plug door for high-speed rail or other railway vehicles. The mechanism comprises a motor, a coupler, a screw, a bearing shaft, a guide rod, a nut, a shaft sleeve, a door carrying rocker, a guide rod sleeve, a door handle, a roller, a roller shaft, a groove cam, a door leaf and a door frame; a spiral mechanism consists of the screw, the nut and the door frame; the guide rod and the nut which are fixedly integrated, a rocker guide rod mechanism consists of the guide rod, the rocker, the guide rod sleeve, the shaft sleeve and the bearing shaft; a groove cam mechanism consists of the bearing shaft, the rocker, the roller, the roller shaft, the groove cam, the door handle, the door leaf, and the door frame; and a composite hinge consists of the guide rod sleeve, the rocker and the door handle; and the spiral mechanism, the rocker guide rod mechanism, and the groove cam mechanism are connected to form the spiral rocker guide rod composite hinge groove cam combination space mechanism.
Description
Technical field [0001] The present invention relates to a sliding plug door screw rocker guide rod compound hinge groove type cam combined space mechanism, which relates to a plug seal opening and closing mechanism of a sliding plug door of a vehicle, in particular to a spiral rocking plug door of a high-speed rail or other rail vehicle Rod guide rod compound hinge groove type cam combined space mechanism. Background technique [0002] The sliding plug doors of rail vehicles are generally two or one. When there are two doors, on the one hand, the opening and closing movement of the two leafs of opposite opening and closing should be realized, and on the other hand, the opening and closing movement of the two leafs should be realized when opening or closing. The inner door leaf has a plug movement to ensure a good sealing effect after closing the door; the aforementioned plug seal opening and closing movement must also be realized when it is a leaf, which is only to achieve a sing...
