Problems solved by technology

[0007] (1) The assembly of the touch screen is inconvenient, and the installation and positioning accuracy is poor, which may be pressed against the touch screen operation area and affect the function of the touch screen;
[0008] (2) There will be severe vibrations during the running of the train, which may cause the touch screen to shake and cause displacement;
[0009] (3) The lack of protection around the touch screen may introduce uncertain interference;
[0010] (4) The metal frame of the LCD screen is in direct contact with the edge of the touch screen. During the vibration process, the LCD screen will press the touch screen, which may cause cracks or even breakage on the edge of the touch screen;
[0011] (5) The insulation between the metal part and the shell is poor, which cannot meet the requirements of electromagnetic compatibility
In addition, there are hidden dangers in relying on the surface treatment of the shell itself for insulation. Once the surface treatment of the display shell is damaged somewhere, the insulation of the display will be reduced;
[0012] (6) It is unreliable to use plastic floating pads to realize the insulation of the LCD screen
None of the above prior art can provide a convenient and safe and reliable installation structure and installation method for the on-board touch screen and liquid crystal screen of the train

Abstract

The invention discloses an installing structure and an installing method for a touch screen and a liquid crystal screen of a train vehicle-mounted display. The installing structure comprises the touch screen, the liquid crystal screen, a display screen front case, a screen installing assembly, a liquid crystal screen rubber pad and a touch screen rubber pad, wherein the screen installing assembly is fixedly arranged at two sides of the liquid crystal screen, the liquid crystal screen rubber pad is pasted at the periphery of the front side of the liquid crystal screen, the touch screen is pasted on the crystal screen rubber pad, and the screen installing assembly is fixedly connected with the display screen front case. The installing method comprises the steps that the screen installing assembly is sheathed at two sides of the liquid crystal screen, the liquid crystal screen rubber pad is pasted at the periphery of the front side of the liquid crystal screen, and the touch screen is pasted on the liquid crystal screen rubber pad; the liquid crystal screen rubber pad is pasted at the inner side of the display screen front case, the edge of the touch screen is in full contact with the liquid crystal screen rubber pad, and finally, the screen installing assembly is fixedly connected with the display screen front case. The installing structure and the installing method have the advantages that the operation is simple, the positioning is accurate, stable and firm, the response accuracy of the touch screen is improved, the casing insulation performance is improved, and the electromagnetic compatibility requirement is met.

Description

technical field [0001] The invention relates to a display device on a train, in particular to an installation structure and an installation method of a touch screen and a liquid crystal screen of a display on a train. Background technique [0002] The on-board display device of the train is an important component on the train, and it is a man-machine exchange interface for directly exchanging information with the driver. It obtains data from the train network equipment to monitor the status of the train in real time, display the status of each equipment on the train and train operation information, record fault information, dump fault data, and prompt the driver for emergency handling of faults. In order to adapt to the working environment (car body) of the train color liquid crystal display device and meet the functional requirements, it should have strong vibration resistance and meet certain electromagnetic compatibility requirements. [0003] Touch screen and LCD scree...
