[0009] Optionally, the guide plate is in an arc structure, and an angle ruler is arranged on the guide plate.

[0010] In summary, the present application has the following beneficial technical effects:

[0011] 1. Set fixed end, mounting frame, connecting hinge, gap adjusting piece, sunshade hat brim, guide plate with angle ruler and scratch-proof rubber pad, avoid the original support after installation, daytime light reflection, single installation position and observation angle, avoid pre-punching during installation, inconvenient disassembly and repair, and problems such as damage to the arc surface of the driver's seat during punching.

[0012] 2. The fixed end and the mounting frame are connected through the connecting hinge to realize angle adjustment, and the guide plate with the angle ruler and the butterfly nut are matched to facilitate quick angle adjustment of the human-machine interface unit, and the butterfly stud is convenient for quickly fixing the fixed end on the cab of the locomotive.

[0013] 3. Add a sunshade hat to avoid the problem of reflection under daytime light, add a gap adjusting piece to adjust the installation gap of the support and the cab contact surface, and add a scratch-proof rubber pad to protect the appearance of the contact surface with the cab hat brim.

[0014] 4. The tail of the gap adjusting piece on the two opposite sides of the fixed end is raised, the friction force of the scratch-proof rubber pad is matched, and under the action of the butterfly stud at the bottom of the fixed end, the fixed end and the cab of the locomotive are fixed.

[0018] The following will be described in detail in combination with the accompanying drawings Figures 1-2 The present application will be further described in detail.

[0019] The embodiment of the present application discloses a multifunctional support for a DMI of a motor train set. As shown in the drawings, Figure 1 and 2As shown, it comprises a mounting frame 1 for the carding human-computer interface unit, the mounting frame 1 is screw-fixed with a light-shielding brim 7 at the edge, the light-shielding brim 7 is in a "U" type structure, and the light-shielding brim 7 is arranged perpendicularly to the mounting frame 1. It also comprises a fixed end 2 for being fixed to the cab of the locomotive, the fixed end 2 is in a "U" type cross section, and the inner wall of the fixed end 2 is screw-fixed with a gap adjusting piece 8 at two opposite sides, and the gap adjusting piece 8 is glued with a scratch-proof rubber pad 9 away from the fixed end 2. The fixed end 2 is provided with screw holes, and the screw holes are provided with butterfly bolts 3, so as to facilitate the quick tightening of the bolts to fix the fixed end 2 to the cab. One end of the fixed end 2 is connected with one end of the mounting frame 1 through a connecting hinge 4, the connecting hinge 4 is prior art, and the fixed end 2 is provided with a guide plate 5 away from the connecting hinge 4, the guide plate 5 is in an arc structure, the mounting frame 1 is rotated through the connecting hinge 4, and the guide plate 5 plays a guiding and deviation correcting role. The guide plate 5 is provided with a guide groove, the guide groove is slidingly connected with a butterfly nut 6 for fixing the rotating angle of the mounting frame 1 and the fixed end 2, and the mounting frame 1 is provided with screw holes matched with the butterfly nut 6. The guide plate 5 is engraved with a protractor.

[0020] The implementation principle of the embodiment of the multi-functional support for the motor train set DMI is as follows: first, the fixed end is placed at the target mounting position of the cab of the locomotive, the support is preliminarily fixed through the butterfly bolts on the fixed end, and at this time, the butterfly bolts are not completely tightened, so as to facilitate the subsequent adjustment of the position.

[0021] According to the size of the cab, the gap adjusting pieces at two opposite sides of the inner wall of the fixed end are adjusted. The position of the fixed end and the cab is closely fitted through the adjustment of the gap adjusting pieces, and at the same time, it is ensured that the scratch-proof rubber pad is in full contact with the surface of the cab, so as to avoid scratching the cab during the installation process.

[0022] When the position and the gap of the fixed end and the cab are adjusted to be appropriate, the butterfly bolts are tightened, and the fixed end is firmly fixed on the cab.
