Detailed implementation mode

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0022] As Figures 1-5 shown, a simulation exercise device for EMU ATP on-vehicle equipment includes a housing 1, an auxiliary screen 3, and a DMI component 2 disposed inside the housing 1. The DMI component 2 includes a display screen 204 fixed to the front side of the housing 1 by bolts, a screen pressing plate 203 connected to the rear side of the display screen 204 by bolts, a main board 201 connected to the rear side of the screen pressing plate 203 by bolts, and a graphics card 202 plugged into the main board 201. The working principle of the DMI component is the same as that of the DMI component in a simulation exercise device for EMU ATP on-vehicle DMI with the authorization announcement number CN206819579U and the patent name "A Simulation Exercise Device for EMU ATP On-vehicle DMI". A main power supply 13 with a voltage of 12V and a power of 200W is disposed on the upper side inside the housing 1. The main power supply 13 is electrically connected to the DMI component. An indicator light panel 24, a push button switch 23, and a knob switch 22 are disposed on the front side of the housing 1. An auxiliary screen tray 5 is slidably connected to the front and rear of the lower end of the front side of the housing 1. The auxiliary screen 3 is located inside the auxiliary screen tray 5. A slide mounting plate 101 is installed inside the housing 1 by bolts. A lead screw slide 8 is installed on the lower side of the slide mounting plate 101 by bolts. A lead screw 9 is rotatably connected to the inside of the lead screw slide 8 through a bearing. A lead screw motor 10 connected to the lead screw 9 is fixed to the rear side of the lead screw slide 8 by bolts. A lead screw slider 7 is threadedly connected to the lead screw 9. A tray connecting plate 6 is fixed to the lower side of the lead screw slider 7 by bolts. The tray connecting plate 6 is connected and fixed to the rear side of the auxiliary screen tray 5 by bolts;

[0023] A drive component capable of driving the lead screw 9 to rotate is disposed inside the housing 1.

[0024] When the user is using the simulation training device, the user presses the button switch 23. Then, under the control of the driving component, the lead screw motor 10 drives the lead screw 9 to rotate, causing the lead screw slider 7 to push the auxiliary screen tray 5 forward, so that the auxiliary screen 3 extends out, facilitating the user's observation. After that, the user can conduct simulation training through the DMI component, the knob switch 22, the indicator panel 24, and the auxiliary screen 3. When the simulation training device is not in use, the user presses the button switch 23 to turn off the simulation training device. Then, the lead screw motor 10 drives the lead screw 9 to rotate in the reverse direction under the action of the driving component, causing the lead screw slider 7 to pull the auxiliary screen tray 5 backward until the front side of the auxiliary screen tray 5 is flush with the front side of the housing 1. At this time, the auxiliary screen 3 is located inside the housing 1, reducing the space occupied by the simulation training device. At the same time, it prevents the auxiliary screen 3 from being collided by the outside world, improves the protection ability of the auxiliary screen 3, and extends the service life of the auxiliary screen 3.

[0025] In this embodiment, the driving component includes a slide table driver 11 fixed to the left side of the slide table mounting plate 101 by bolts. The slide table driver 11 is electrically connected to the lead screw motor 10. During use, the user can control the rotation of the lead screw motor 10 through the slide table driver 11, thereby controlling the forward and backward movement of the auxiliary screen tray 5, improving the convenience of the user when controlling the forward and backward movement of the auxiliary screen tray 5.

[0026] In this embodiment, two photoelectric switches 17 are fixed to the lower side of the right end of the slide table mounting plate 101 by bolts. A blocking strip 18 that moves between the two front and rear photoelectric switches 17 is fixed to the right side of the tray connecting plate 6 by bolts. The two photoelectric switches 17 are electrically connected to the slide table driver 11. During use, the blocking strip 18 can move forward and backward following the tray connecting plate 6. When the blocking strip 18 blocks the front photoelectric switch 17, at this time the auxiliary screen 3 completely extends out of the housing 1, and the photoelectric switch 17 transmits a signal to the driving component to control the lead screw motor 10 to stop rotating, preventing the auxiliary screen tray 5 from completely detaching from the housing 1. When the blocking strip 18 blocks the rear photoelectric switch 17, at this time the front side of the auxiliary screen tray 5 is flush with the front side of the housing 1, and the photoelectric switch 17 transmits a signal to the driving component to control the lead screw motor 10 to stop rotating, preventing the auxiliary screen tray 5 from hitting the housing 1 and being damaged. Thus, the accuracy of the user when controlling the position of the auxiliary screen tray 5 is improved, and the reliability of the auxiliary screen tray 5 during use is improved.

[0027] In this embodiment, two slide rails 16 are symmetrically arranged on the lower side of the auxiliary screen tray 5 by bolts. A slide rail mounting strip 15 is fixed to the lower side inside the housing 1 by bolts. The slide rails 16 can slide forward and backward on the slide rail mounting strip 15. When the auxiliary screen tray 5 moves forward and backward, the slide rails 16 slide forward and backward inside the slide rail mounting strip 15, keeping the moving direction of the auxiliary screen tray 5 always within the slide rail mounting strip 15, preventing the auxiliary screen tray 5 from deviating from the fixed direction and colliding with the housing 1.

[0028] In this embodiment, a plurality of screen pressing strips 4 connected to the lower side of the auxiliary screen 3 are fixed to the upper side of the auxiliary screen tray 5 by bolts. The screen pressing strips 4 are inclined upward from front to back. During use, the screen pressing strips 4 cause the auxiliary screen 3 to be inclined upward from front to back, improving the convenience for staff to observe the auxiliary screen 3.

[0029] In this embodiment, a plurality of heat dissipation holes 102 are provided on the left and right sides and the rear side of the housing 1. During use, the heat generated by the electronic components in the housing 1 can be discharged through the heat dissipation holes 102, thus ensuring the normal operation of the electronic components and improving the heat dissipation performance of the simulation training device.

[0030] In this embodiment, a handle 14 is fixed to the upper side of the housing 1 by bolts. When moving the simulation training device, the staff can lift the housing 1 through the handle 14, thus improving the convenience when moving the simulation training device.

[0031] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
