Description

Technical Field

[0001] The utility model relates to the field of engineering vehicles, in particular to a visual operation auxiliary device for a loader cab. Background Art

[0002] Loader is a kind of engineering machinery widely used in engineering construction, mining, docks and other fields; it mainly has the following characteristics and functions:

[0003] Strong loading capacity: can quickly and efficiently shovel and carry large amounts of materials, such as sand, earth, ore, etc. Flexible mobility: can move and operate freely in various complex terrains and sites; load and transport ore in mines;

[0004] The following are some common operating aids in the loader cab:

[0005] Display instruments: such as water temperature gauge, oil temperature gauge, oil pressure gauge, etc., to help the driver understand the working status of the loader in real time;

[0006] Monitoring display screen: can display the rear view or the operation status of the working device, etc.;

[0007] Visual navigation system: It helps drivers to reach the work site and plan the route accurately;

[0008] Walkie-talkie system: used to communicate with the command center or other vehicles;

[0009] Air conditioning system: adjusts the temperature and humidity in the cab to provide a comfortable working environment;

[0010] Sound system: relieve work fatigue;

[0011] The visual navigation system mainly includes the navigation display screen. During daily operation, drivers are prone to spilling water on the surface of the display screen, which may form a layer of water film on the screen surface. This layer of water film will interfere with the conduction of touch signals, resulting in the inability to accurately recognize touch commands. If water enters the circuit part inside the display screen, it may cause a short circuit or damage electronic components, thereby affecting the normal operation of the touch function;

[0012] When driving at night, the glare caused by an overly bright display screen will attract the driver's attention and divert his or her sight from the road, resulting in untimely observation of the road conditions, pedestrians, vehicles, etc. ahead, increasing the risk of collision.
