[0035] For details, see Figure 1 、 2 The upper cabinet body 1 includes a left side panel 7, a top panel 9, a right side panel 8, a bottom panel 10, an upper cabinet body rear cover, a plurality of panels 11 and an inner bracket 12.

[0036] The upper cabinet body 1 is a rectangular frame structure as a whole, and each component is connected and assembled by screws. The left side panel 7, top panel 9, right side panel 8, and bottom panel 10 are connected in sequence to form the upper cabinet frame, and the inner bracket 12 is fixedly installed in the upper cabinet frame. The inner bracket 12 is a cross-beam structure, consisting of multiple horizontal panels and vertical panels perpendicular to the horizontal panels. The inner bracket 12 divides the interior of the upper cabinet frame into multiple installation areas, including a display control area 3, an operation control area 4, and a communication control area 5. Each installation area is also divided into one or more specific module installation areas according to specific installation requirements. The horizontal panels and vertical panels of each module installation area are provided with installation holes for installing the corresponding control device module on the inner bracket 12. The various components of the upper cabinet body 1 are all machined from aluminum plates, and the joints of two adjacent components adopt a groove and ridge connection structure, that is, a groove is provided on the edge of one component, and a ridge matching the groove is provided on the edge of the other component to be spliced with it. The ridge is embedded in the groove and then fastened with screws. This structure is used to increase the contact surface of the connection and improve the strength of the upper cabinet body 1.

[0037] Furthermore, the display control area 3, located at the top of the upper cabinet 1, is used to house equipment modules such as power distribution, servo systems, or dedicated display screens. The operation control area 4, located below the display control area 3, is used to house laptop computers or equipment control screens.

The control equipment modules within the display control area 3, operation control area 4, and communication control area 5 are arranged in a basic top-down, left-to-right order, meeting ergonomic design principles and significantly improving operator efficiency.

[0038] Each module installation area of the inner bracket 12 of the cross structure is used to install the corresponding control device module. The size of each cross-shaped separation area of the inner bracket 12, that is, the module installation area, is determined according to the control device module to be installed. A corresponding panel 11 is provided outside each control device module for operating the corresponding module. The panel is installed on the front of the console, that is, the side facing the operator. The panel 11 is fixedly connected to the inner bracket 12, and its corresponding control device module is shielded inside the upper cabinet 1. The panel 11 is opened according to the size of the operating surface of each control device module, and the edge of the opening is designed with a widened chamfered shape. An upper cabinet rear cover is installed on the rear of the upper cabinet 1 facing away from the installation side of the panel 11, which is used to close the rear side of the upper cabinet 1. The four edges of the upper cabinet rear cover are respectively connected to the left side panel 7, the top panel 9, the right side panel 8, and the bottom panel 10.

[0039] See Figure 2 、 4 5. The operation control area is located on the front side of the console, that is, on the side facing the operator. The flip table 13 is provided to facilitate the operation and storage of the equipment in the operation control area. The lower ends of the flip table 13 are hinged to the left side plate 7 and the inner bracket 12 through a set of double cylindrical sleeve rotating pairs 14. The middle part of the upper end of the flip table 13 is locked by a rotary lock 22. Therefore, the flip table 13 has two working states, one of which is the flip open state. At this time, the flip table 13 is as shown in FIG. Figure 4 The flip platform 13 is shown in a horizontally unfolded position, supporting the control equipment installed in the operation control area. The flip platform 13 is in a retracted and locked position, with the upper end of the flip platform 13 locked with the rotary lock 22, protecting the equipment installed inside the flip platform 13. During transportation or marching, the flip platform 13 can be retracted and embedded in the upper cabinet 1 and locked with the rotary lock 22.

[0040] The design of the flip table 13 enables the operator to quickly and conveniently switch between working and marching. When working, the operator quickly folds up the flip table 13 and turns the rotary lock 22 to switch to the marching state. When marching, the operator can also turn the rotary lock 22 to open the flip table 13 and quickly enter the working state.

[0041] For further information, see Figure 4 、 5The double cylindrical sleeve rotating pair 14 includes a rotating lug 20 and a rotating shaft bracket 21. The two rotating lugs 20 are symmetrically mounted on both sides of the lower end of the flip table 13. One end of the rotating lug 20 is fixedly connected to the flip table 13 by screws, and the other end of the rotating lug 20 is provided with a cylindrical rotating shaft for hinged cooperation with the rotating shaft bracket 21. The two rotating shaft brackets 21 correspond one-to-one to the two rotating lugs 20 and are respectively fixedly mounted on the inner side of the left side plate 7 and the side of the inner bracket 12 facing the flip table 13. The rotating shaft bracket 21 is provided with a sleeve at the back of its mounting end for rotational cooperation with the rotating shaft set. During installation, the rotating shafts of the rotating lugs 20 on both sides are correspondingly inserted into the sleeves of the rotating shaft bracket 21 to realize the rotational connection between the rotating lugs 20 and the rotating shaft bracket 21, thereby realizing the flippable hinge of the flip table 13. In this embodiment, the rotating lugs 20 and the rotating shaft bracket 21 are both made of stainless steel, and the structural design is simple and has good reliability.

[0042] See Figure 2 、 6 7. The lower end of the flipping plate 13 is flipped and limited by two locking frames 23, which limit the flipping plate 13 to a horizontal state to avoid excessive flipping. Figure 7 The locking frame 23 is an integral Z-shaped structure, comprising a limit plate, a mounting plate, and a vertical plate. The limit plate and the mounting plate are arranged horizontally and parallel to each other, with the vertical plate located between the limit plate and the mounting plate. The mounting plate is located at the lower end of the locking frame 23 and is used to mount the locking frame 23. The limit plate is located at the upper end of the locking frame 23 and is used to limit the position of the flip table 13. The mounting plate is fixedly connected to the base plate 10 by screws, fixing the locking frame 23 to the inner side of the flip table 13. The two locking frames 23 are arranged side by side in a row. The limit plate faces the flip table 13. When the flip table 13 is unfolded to a horizontal position, the lower end surface of the limit plate contacts the inner side surface of the lower end of the flip table 13, thereby restricting the flip table 13 from further flipping. The high security of the locking frame 23 ensures that the flip table 13 can be flipped to a horizontal position, thereby effectively supporting the control equipment in the operation control area, such as a laptop computer. When working, the laptop computer can be directly placed on the horizontal flip table 13.

[0043] See Figure 6 The rotary lock 22 is used to lock the flip table 13 after it is retracted. Specifically, the rotary lock 22 is installed on the inner bracket 12 through the rotary lock support plate 24. The rotary lock support plate 24 is fixedly connected to the inner bracket 12 and is located directly above the flip table 13. The rotary lock 22 is installed in the middle of the rotary lock support plate 24. A groove is provided at the top of the flip table 13 for locking with the lock tongue of the rotary lock 22. A rubber strip 25 is provided at the lower end of the rotary lock support plate 24. When the flip table 13 is locked, the upper edge of the flip table 13 is pressed into contact with the rubber strip 25. The rubber strip 25 uses its own compression to provide pre-tightening force to the lock tongue. Rotate the rotary lock 22 so that its lock tongue is located in the groove of the flip table 13 to lock the flip table 13.

[0044] Referring to 1 and 3, the lower cabinet 2 is installed below the upper cabinet 1. The top of the lower cabinet 2 is open, and the top circumference is fixedly connected to the bottom plate 10 of the upper cabinet 1 by screws. Specifically, the lower cabinet 2 includes a lower cabinet left side panel 15, a lower cabinet front inclined panel 18, a lower cabinet right side panel 16, a lower cabinet bottom plate 17, a lower cabinet front cover plate and a lower cabinet rear cover plate, and each component is connected and assembled by screws. The lower cabinet left side panel 15 and the lower cabinet right side panel 16 are parallel and are both vertically installed at the two ends of the horizontally arranged lower cabinet bottom plate 17. The two ends of the lower cabinet front inclined panel 18 are fixedly connected to the front inclined surfaces of the upper ends of the lower cabinet left side panel 15 and the lower cabinet right side panel 16 respectively. The lower cabinet rear cover plate connects the lower cabinet left side panel 15, the lower cabinet right side panel 16 and the lower cabinet bottom plate 17 to close the rear side of the lower cabinet 2. The left side panel 15 of the lower cabinet, the front inclined panel 18 of the lower cabinet, the rear cover panel of the lower cabinet, the right side panel 16 of the lower cabinet, and the bottom panel 17 of the lower cabinet are connected together to form the lower cabinet frame. The various components of the lower cabinet 2 are all machined from aluminum plates, and the joints of two adjacent components also use a connection structure of grooves and ridges, that is, a groove is provided on the edge of one component, and a ridge matching the groove is provided on the edge of the other component to be spliced with it. The ridge is embedded in the groove and then fastened with screws. The connection structure of the groove and ridge is used to increase the contact surface of the joint and improve the strength of the lower cabinet 1. A mounting bracket 19 is fixed in the lower cabinet frame. The mounting bracket 19 is used to fix and install auxiliary equipment such as serial port servers and switches. The front cover panel of the lower cabinet closes the opening of the lower cabinet 2 located below the front inclined panel 18 of the lower cabinet. The installation and removal of auxiliary equipment can be carried out by opening the front cover panel of the lower cabinet.

[0045] In this embodiment, the inner bracket 12 and the mounting bracket 19 facilitate the integration and expansion of different electronic devices, and the interfaces can be changed according to needs.

[0046] See Figure 8 The highly integrated console of this embodiment is installed in the interior cabin of the Mengshi vehicle 26. The upper cabinet 1 and the roof, and the lower cabinet 2 and the floor are connected via shock absorbers 6. According to actual needs, a console can be installed on both sides of the rear row, or only on one side.
