Problems solved by technology

[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 double-rocker composite hinge 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 a spiral double-rocker composite hinge groove 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 shaft sleeve, a nut, a short rocker, a door carrying rocker (a rocker for short), a connection rod, a door handle, a roller, a roller shaft, a groove cam, a door leaf and a door frame, wherein a spiral mechanism consists of the screw, the nut and the door frame; a double-rocker mechanism consists of the bearing shaft, the shaft sleeve, the short rocker, the rocker, and the connection rod; 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; a rotation pair consists of the upper end of the connection rod and the short rocker; a composite hinge consists of the lower end of the connection rod, the rocker and the door handle; and the spiral mechanism, the double-rocker mechanism and the groove cam mechanism are connected to form the spiral double-rocker composite hinge groove cam combination space mechanism.

Description

technical field [0001] The present invention relates to a spiral double-rocker composite hinge groove type cam combination space mechanism for a plug door, which relates to a plug seal opening and closing mechanism for a plug door of a vehicle, in particular to a spiral plug door for a high-speed rail or other rail vehicles. Double-rocker composite hinge-groove cam combined space mechanism. Background technique [0002] Rail vehicle plug doors generally have two or one leaves. When there are two leaves, on the one hand, it is necessary to realize the opening and closing movement of the two leaves of the doors that are opened and closed. The inner door leaf pulls movement to ensure a good sealing effect after closing the door; when it is one leaf, the above-mentioned plug seal opening and closing movement is also realized, only to realize the single opening and single closing of one leaf. [0003] In order to realize the function of opening and closing the sliding door, the ...
