A load-carrying driving device for a sliding door of a vehicle

Abstract

The invention provides a load-carrying driving device for a vehicle sliding door, belonging to the technical field of rail transit, comprising: a frame, a motor installed at one end of the frame, wherein the output end of the motor is connected with a transmission part; The frame is installed in the middle of the frame, and the transmission part runs through the hanger; two transmission mechanisms are respectively located on both sides of the hanger, and one end of each transmission mechanism is screwed on the transmission part, and the other end of each transmission mechanism A door leaf is connected, wherein each transmission mechanism includes a four-bar linkage assembly, through the extension and retraction of the four-bar linkage assembly, the smoothness and plugging of the door leaf are realized. The invention provides a load-carrying driving device for a vehicle sliding door, which realizes the opening and closing of the vehicle door leaf and the plugging action through a four-link assembly. Due to the height difference problem of the swing mechanism, the occupied space of the whole device is small.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and relates to a driving device, in particular to a bearing driving device for a sliding door of a vehicle. Background technique [0002] With the development of urban rail and bus door systems, there are higher requirements for the functionality and reliability of the sliding door mechanism. As a key component, the sliding door mechanism is directly related to the operation function of the door system. [0003] The sliding door mechanism is widely used in the vehicle door system of urban rail vehicles and public transport vehicles. Most of the sliding door mechanisms at home and abroad are mainly divided into the following three types: the first one is to realize the switch in the direction of the X axis with the optical axis as the guide Door, the Y-axis direction realizes the plug-and-pull action, but it takes up a lot of space and has low synchronization; the second type uses the optical...

[0003] The sliding door mechanism is widely used in the vehicle door system of urban rail vehicles and public transport vehicles. Most of the sliding door mechanisms at home and abroad are mainly divided into the following three types: the first one is to realize the switch in the direction of the X axis with the optical axis as the guide Door, the Y-axis direction realizes the plug-and-pull action, but it takes up a lot of space and has low synchronization; the second type uses the optical axis as the guide to realize the opening and closing of the door in the X-axis direction, and the Y-axis direction realizes the plug-and-pull action through the swing rod mechanism However, the length of the mechanism is long, there is a height difference in the process of opening and closing the door, and the resistance is relatively large at the moment of opening and closing the door; the third type is guided by a linear guide rail to realize the opening and closing of the door and the plug in the X-axis and Y-axis directions. However, its own mechanism is complicated, and it is difficult to install and debug
