A train anti-pinch door

Abstract

The invention relates to a train anti-pinch door, comprising a train body, a door driving device, and an anti-pinch door, the door drive device is fixed on the inner rear top side of the train body, and the anti-pinch door is arranged on the train body The front side, and the top side of the anti-pinch door is connected to the door driving device, the bottom side of the anti-pinch door is connected to the front bottom side of the train body, and the front bottom side of the train body is provided with symmetrical door bottom slideways. The invention optimizes the setting of the train door, changes the direct push structure of the traditional smooth door, and designs an anti-pinch structure, which can make the door automatically stop closing to the inside when encountering resistance, keep hovering, and avoid secondary damage , The driving principle of the anti-pinch door is simple, suitable for application on various anti-pinch doors, while protecting the safety of passengers, the door itself does not need to be greatly improved, it adopts a purely mechanical structure, and the installation cost is low, so it should be popularized and used.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a train anti-pinch door. Background technique [0002] Trains refer to trains in rows, which are divided into two types, railway trains: trains, which are in general form, road trains: group cars, car groups, road car groups, and mine transport vehicles in Australia There are also high-speed railway trains in my country. In our country, the doors on the trains are generally smooth doors. The smooth doors use the principle of sliding to open and close the doors. There are often situations where people are pinched in the door. The light ones cause flesh injuries, and the severe ones cause fractures. However, the existing door and window anti-pinch structures are realized by using infrared sensors, controllers and other electrical principles, which are expensive and easy to damage. There is no longer any pinching accident in the door of the train, so a train anti-pinching door realized by a pu...

[0002] Trains refer to trains in rows, which are divided into two types, railway trains: trains, which are in general form, road trains: group cars, car groups, road car groups, and mine transport vehicles in Australia There are also high-speed railway trains in my country. In our country, the doors on the trains are generally smooth doors. The smooth doors use the principle of sliding to open and close the doors. There are often situations where people are pinched in the door. The light ones cause flesh injuries, and the severe ones cause fractures. However, the existing door and window anti-pinch structures are realized by using infrared sensors, controllers and other electrical principles, which are expensive and easy to damage. There are no more pinching accidents in the doors of trains, so a train anti-pinching door realized by purely mechanical structure principles is designed
