The signal niche box 5 adopts a wall door and is provided with interfaces such as network port, video, audio, external output power supply, and AC power access, which can be used for power supply and large screen cable connection.

[0058] like Figure 7 As shown, the chassis 2 of the trailer adopts a steel body, mainly using Q345B profiles. After welding, the overall electrophoresis process is completed, and then the surface is sprayed, which has good anti-corrosion performance. After the overall completion, infrared camouflage coating and corresponding camouflage painting are sprayed.

[0059] Furthermore, the trailer chassis 2 is a dual-axle, four-wheel load-bearing vehicle with front-wheel steering; the trailer chassis 2 includes: a frame 27 and a wheel assembly 29, a traction assembly 26 and a telescopic ladder 28 arranged on the frame 27; wherein the frame 27 is made of Q345B profile, and after welding, the overall electrophoresis process is performed, and then the surface is sprayed, which has good anti-corrosion performance; the frame 27 is the load-bearing body, and the wheel assembly 29, the traction assembly 26 and the telescopic ladder 28 are installed. The wheel assembly 29 is a wheel-type air brake, and the front and rear axle four wheels are equipped with pneumatic brakes. The wheel assembly 29 uses a steel plate shock absorber for vibration reduction, which has high rigidity and high load-bearing performance.

[0060] Furthermore, if Figure 8 The telescopic cabin ladder 28 shown is installed at the rear end center position of the frame 27 and has a telescopic function, that is, when not in working state, it can be retracted into the frame 2 without occupying external space, and can be pulled out when in use; the pedal of the telescopic cabin ladder 28 is fixed by a pin shaft and can be folded up according to the state of the cabin ladder, and unfolded to have a foot-operated cabin stepping function.

[0061] Furthermore, if Figure 9-12 As shown, the traction assembly 26 includes: a traction frame 30, a bogie 31, a locking mechanism 33 and a slewing support 32; the traction frame 30 adopts an A-shaped structure, and the top end is a circular ring body, which can be rotated through a pin shaft, and this end is used to connect with the tractor; the lower end of the traction frame 30 is connected to the bogie 31 through a pin shaft, and the bogie 31 is connected to the two front wheels, so as to achieve traction steering; the bogie 31 is installed on the frame 27 through a slewing support 32 (similar to the role of a bearing), and the slewing support 32 has an inner ring and an outer ring that can rotate relative to each other (similar to a bearing), and the bogie 31 is connected to the inner ring of the slewing support 32 by bolts, and the inner ring of the slewing support 32 can rotate and play a supporting role at the same time; the outer ring of the slewing support 32 is connected to the frame 27 by screws.

[0062] The lower end of the traction frame 30 is connected to the bogie 31 through a pin shaft and can rotate around the pin; when in a non-traction state, the traction frame 30 rotates upward to a vertical state and is locked in position through a locking mechanism 33. The locking mechanism 33 includes a locking hook arranged at the lower end of the traction frame 30 and a locking rod arranged on the bogie 31; more than two locking hooks are installed on a cross bar at the lower end of the traction frame 30, and the cross bar is rotatably connected to the traction frame 30; the end of the locking hook has a downward curved hook; when the traction frame 30 rotates upward to a vertical state, the locking hook is hooked on the locking rod 39 on the bogie 31, thereby achieving position locking.

[0063] like Fig.13As shown, the large screen system 3 includes: a large screen (including a frame, which is not shown in the figure), a connecting frame 35, two sets of lifting devices 34, a frame 36, etc. Among them, the large screen lifting system control box 20 is installed on the inner wall of the cabin and connected to the external lifting device 34 through cables.

[0064] The large screen is spliced, consisting of several combined module screens. The large screen module has a large overall weight. In order to avoid damage to the large screen during the operation of the motorized cabin, the large screen is installed on site, that is, it is installed on the side wall of the cabin body 1 when in use. To facilitate the installation of the large screen, a lifting device 34 is used to lift the connecting frame 35 of the large screen (when installation is required, the connecting frame 35 is lowered to facilitate installation. After the installation is completed, the connecting frame 35 with the large screen installed is raised to a set height position according to the needs of use to perform screen projection), and the stability and reliability of the lifting are guaranteed.

[0065] Specifically: a frame 36 is provided on the side wall of the cabin 1 to meet the load-bearing requirements; two lifting devices 34 are installed in parallel on the top crossbar of the frame 36, and the actuating ends of the lifting devices 34 are vertically downward and can be extended and retracted in the vertical direction; a connecting frame 35 is installed at the actuating ends of the two lifting devices 34; the connecting frame 35 is used to install a large screen (the large screen can be detachably connected to the connecting frame 35); as an example, the large screen is a 3500mm×2000mm seamless large screen assembled by a frame assembly, which is an important equipment for combat command and temporary meetings; when it needs to be installed, the height of the connecting frame 35 is lowered by using two lifting devices 34, and then the large screen is installed on the connecting frame 35 by bolts. In this way, the lifting and lowering of the spliced ​​large screen is realized by the lifting device 34, which is convenient for the flexible development of activities, saves manpower and time, and improves the quality of activities.

[0066] The lifting device 34 is further electrically controlled, and the actuator is a servo electric cylinder, which can achieve a lifting function of not less than 800 mm.

[0067] like Fig.14 As shown, the leveling system 4 is used to realize the auxiliary leveling support function of the mobile cabin when the ground is uneven or the large screen is working; the leveling system includes: four hydraulic cylinders 38, a control hydraulic station 37 and a leveling system control box 25 arranged in the cabin body 1;

[0068] Furthermore, four hydraulic cylinders 38 are installed at the four corners of the trailer chassis 2 to play a supporting role; the control hydraulic station 37 is integrated and installed at the bottom of the trailer chassis 2 to control the four hydraulic cylinders 38. The leveling system control box 25 is installed on the front wall of the cabin, and is connected to the control hydraulic station 37 through cables, and the adjustment is achieved through indoor operation.

[0069] Furthermore, the leveling system 4 can realize the adjustment of a single hydraulic cylinder 38 , and can also realize the coordinated telescopic action of four hydraulic cylinders 38 .

[0070] For the power supply of the equipment in the cabin, the main wiring in the cabin adopts the internal wiring method. The network port, audio, video and power supply port are set on the wall panel of the operating table, which can be used for the needs of the operating table, and a display can be installed for real-time monitoring.

[0071] In addition, cabin 1 is also equipped with supporting equipment, mainly including UPS power supply system, cabinet, lightning protection and grounding facilities (ground anchor, grounding wire, grounding copper busbar), cabin lighting, emergency lighting, anti-electric shock power supply cables, AC power cable reel, intercom, real-time monitoring system, etc.

[0072] A UPS power system is installed in the cabin. Under normal working conditions, the system is powered by the AC power supply or power supply vehicle connected through anti-electric shock power supply cables and AC power cable trays. In the event of a power outage, the UPS can provide power supply for all equipment in the cabin for more than 30 minutes.

[0073] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
