Embodiment Construction

[0012] Control attached figure 1 , In the Cartesian coordinate system, in two planes parallel to the YZ plane, there are 2 multi-bar mechanisms 1 to constrain the connecting rods in the Z-axis direction 2 to restrict the linkage mechanism to move in the YOX plane and increase the connecting rods The stiffness.

[0013] The top restraint 5 is set in two planes parallel to the XY plane, and is pressed on the top of the door leaf 3. At the moment of the initial movement of the door leaf, the reaction force R of the top restraint 5 3 And R 4 Balanced door opening thrust F 3 Pre-stored force F on both sides 1 And F 2 The component force in the Y-axis direction prompts the door leaf 3 to perform translational movement first. After the door leaf 3 is translated along the X-axis direction to release the constraint, the door opening thrust F 3 Pre-stored force F on both sides 1 And F 2 The door leaf 3 flips upward under the combined force of, so as to realize the movement of the door leaf...

Abstract

The invention relates to a multibar bearing and motion guiding mechanism of a tilt-up door. In a rectangular coordinate system, two multibar mechanisms are arranged in two planes parallel to plane YZ to restrain the connecting bar in the Z axis direction, and the top restraint is arranged in two planes parallel to plane XY and pressed at the top of the door leaf; the counterforce of the top restraint balances the door opening thrust force and component force of the preserved force on two sides in the Y axis direction, to enable the door leaf to make translational motion first; after the door leaf translates in the X axis direction and releases the restraint, the door leaf is tilted up under the function of the resultant force of the door opening thrust force and the preserved force on two sides. The mechanism has the advantages that the problem that the tilt-up door can not rotate because of the interference of the boundary of the interface area between the tilt-up door and the vehicle body is solved, The motion track of the door leaf is effectively controlled, and the collision between the door leaf and the side of the vehicle body in the door opening process is avoided. The mechanism also has the advantages that the installation is convenient, the reliability is high, and the mechanism is suitable for various vehicles with complex outlines. The dimension of the multibar mechanism is only required to be adjusted to adapt to the interface conditions of the specific outlines of the vehicles.

Description

Technical field [0001] The invention relates to a multi-pole bearing and movement guiding mechanism for an upturn door, which belongs to the technical field of urban rail vehicle door systems. Background technique [0002] The contour of the vehicle is becoming increasingly complex and changeable. The existing fixed hinge type bearing and movement mechanism, that is, the door leaf and the door frame are hinged coaxially to realize the door upturn. When the curvature of the interface area of ​​the door changes greatly, the door leaf with a fixed hinge structure will interfere with the boundary of the interface area when it moves and cannot rotate. Summary of the invention [0003] The purpose of the present invention is to overcome the defects of the above-mentioned mechanism, and propose a multi-bar loading and movement guiding mechanism for an upturn door, which can control the movement trajectory of the door leaf and meet the design requirements of complex vehicle contours. ...
