Spiral double-rocker guide rod groove cam combination space mechanism for sliding-plug door

Abstract

The invention discloses a spiral double-rocker guide rod groove cam combination space mechanism for a sliding-plug door, relates to a sliding and plug, sealing, opening and closing mechanism for the sliding-plug door for a vehicle, in particular to the spiral double-rocker guide rod 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 guide rod, a guide rod sleeve, a shaft sleeve, a door carrying rocker, a nut, a short rocker, 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 guide rod mechanism consists of the rocker, the short rocker, the guide rod, the guide rod sleeve, the nut, the bearing shaft, and the shaft sleeve; 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; the spiral mechanism, the double-rocker guide rod mechanism, and the groove cam mechanism are connected to form the spiral double-rocker guide rod groove cam combination space mechanism; the door frame is fixedly connected with a vehicle body; and the motor which is fixed on the door frame is connected with the screw through the coupler.

Description

technical field [0001] The present invention relates to a spiral double rocker guide rod 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 screw for a plug door of a high-speed rail or other rail vehicles. Double rocker guide rod 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 existing slidin...

AI Technical Summary

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
