In some large-scale comprehensive exercise training scenarios, the commander needs to view the exercise content and real-time exercise data at the same time in the vehicle-mounted or ground temporary command control room. The double-screen portable computer can also be used to achieve this purpose.
[0003] At present, there are some double-screen computer designs on the market, which are usually designed to be unfolded horizontally or vertically. However, most of the current double-screen computer designs need to design a back support behind the main screen and the auxiliary screen to provide fixation and horizontal sliding of the main screen and the auxiliary screen. This makes the double-screen design thicker and heavier, which is not conducive to its portability. In addition, no matter how the main screen and the auxiliary screen are unfolded, the two screens are in the same plane and can only be viewed by the user in front of the computer, which cannot meet the need of viewing the screen content on both sides of the computer at the same time in some use environments.

[0042] The sliding limiting mechanism 5 comprises a sliding part and a limiting part,
[0043] The sliding part: the main screen module 2 comprises a main screen, a T-shaped sliding block 7 and a guide, the guide comprises a guide front plate 6 and a guide rear plate 8, the guide front plate 6 and the guide rear plate 8 are spliced and fixed to form a guide sliding groove matched with the T-shaped sliding block 7; the guide is connected with the base module 1 through the double-shaft synchronous damping rotating shaft 4, and the main screen is slidingly connected with the guide through the T-shaped sliding block 7. The T-shaped sliding block 7 can slide horizontally in the guide sliding groove formed by the guide front plate 6 and the guide rear plate 8.
[0044] The T-shaped sliding block 7 is connected and fixed with the main screen through an embedded structure and locking screws. Two rectangular grooves and three screw fixing holes are designed on the T-shaped sliding block 7, two rectangular protruding structures are arranged on the main screen shell and embeddedly assembled with the two rectangular grooves on the T-shaped sliding block 7 in a tight fit state, and three fastening screws pass through the fixing holes on the T-shaped sliding block 7 to connect the T-shaped sliding block 7 with the main screen shell.

[0054] Through the decoding and switching function, the secondary screen displays the remote terminal interface and switches the keyboard and mouse control.
[0055] The secondary screen reserves a quick key function to turn off the screen, when there is no operator on the back of the computer, the secondary screen can be directly turned off through the quick key.
[0056] The dual-screen portable computer, the connection between the secondary screen and the primary screen uses at least two double-shaft 360° synchronous damping shafts. Due to the application of this special damping shaft, the secondary screen is only connected and fixed to the primary screen, and the secondary screen is hung on the right side of the primary screen after being unfolded. At the same time, thanks to the application of the double-shaft 360° synchronous damping shaft, the secondary screen can not only be unfolded horizontally by 180°, so that the secondary screen and the primary screen are unfolded in the same plane and follow the primary screen to slide horizontally to the center, but also can be further flipped back by 360°, so that the secondary screen is completely flipped to the back of the primary screen, and the computer is observed as a single-screen computer state from the front side. At this time, the primary screen and the secondary screen are in front and back, so that the users on both sides of the computer can view the display content at the same time, which meets the application requirements in some special use scenarios.
