By providing the driver's cab hood 20, the scope of the driver's cab steel structure 10 is reduced, the manufacturing costs of molds, inspection tools, bending parts, etc. are reduced, and economic efficiency is improved. The density of the fiberglass reinforced plastic of the cab head cover 20 is lower than that of carbon steel, and reducing the range of the cab steel structure 10 helps to achieve lightweighting of the cab head structure.

[0116] In addition, the parting position of the cab hood 20 and the cab steel structure 10 should be on a simple, smooth surface with a small curvature change, so as to facilitate the streamlined matching of the cab hood 20 and the cab steel structure 10 during installation, while reducing the difficulty of manufacturing the skeleton and skin components of the cab steel structure 10 and improving economy; the curvature of the parting position between the cab hood 20 and the side wall of the cab steel structure 10 is small, and the position where the curvature of the side surface and the top surface change greatly is located on the fiberglass hood; the interface between the cab hood 20 and the front wall 11 and the rear end wall 12 is a two-dimensional surface.

[0117] The driver's cab steel structure 10 provides installation interfaces for movable windows and fixed windows, and thus the installation interfaces are respectively distributed on the driver's cab hood 20 and the driver's cab steel structure 10. It can be understood that the above-mentioned installation interfaces are respectively fully provided by the driver's cab hood 20 or the driver's cab steel structure 10, so as to avoid a certain component interface crossing the gap between the driver's cab steel structure 10 and the driver's cab hood 20, which makes the installation of the component difficult. Specifically, the driver's cab steel structure 10 includes a front wall component 11, a rear end wall component 12, a waist beam component 14, a roof curved beam component 18, and two side wall components 13 arranged opposite to each other in the transverse direction. The waist beam component 14 connects the front wall component 11 and the side wall component 13 respectively; the side wall component 13 connects the front wall component 11 and the rear end wall component 12 in the longitudinal direction, and the side wall component 13 has a movable window installation interface and a fixed window installation interface.

[0125] Since the opening and closing mechanism, hood, etc. are heavier than other installed components, in order to ensure the installation reliability of the opening and closing mechanism and the hood, a front wall reinforcement plate 1113 is set in the outer contour area of the front wall main board 1111. The outer contour of the front wall reinforcement plate 1113 is consistent with the top contour of the parting position of the driver's cab hood 20, and the inner contour of the front wall reinforcement plate 1113 is set according to the lightweight principle (minimum area) of the connection point of the hood and the opening and closing mechanism to achieve lightweight.

In order to ensure the strength and rigidity of the front wall component 11, a plate beam structure 1112 for reinforcement is provided on the inner panel surface of the front wall main panel 1111 facing the interior of the driver's cab. The plate beam structure 1112 includes a number of front wall cross beams 11121 and front wall longitudinal beams 11122 that are staggered horizontally and vertically, as well as a transverse reinforcement beam 11123. The brake pipe installation interface 1114, the electric whistle and bagpipe installation interface 1115 are respectively opposite to the horizontal and vertical intersection points of the plate beam structure 1112 on the inner panel surface on the outer panel surface of the front wall main panel 1111, and the plate beam structure 1112 provides support for each installation interface, thereby avoiding electric shock. The flute / bagpipe and brake pipe are deformed after welding; wherein, the front wall cross beam 11121 and the front wall longitudinal beam 11122 can be respectively set as L-shaped angle irons, and the L-shaped angle iron includes a first surface 111211 and a second surface 111212 perpendicular to each other, the first surface 111211 is in contact with the front wall main board 1111, and the second surface 111212 is perpendicular to the front wall main board 1111; the front wall cross beam 11121 and the front wall longitudinal beam 11122 are respectively continuously arranged at the first surface 111211 and the second surface 111212 at the intersection; thereby, the lateral load and the longitudinal load at the intersection can be continuously transmitted.Taking the example of setting 4 front wall longitudinal beams 11122 and 2 groups of front wall cross beams 11121, with 3 beams in each group, the top of the front wall longitudinal beam 11122 is close to the front wall reinforcement plate 1113 to ensure the transmission of the longitudinal load, while leaving an adjustment amount, such as a 1.5-3.5mm gap; at the intersection of the front wall cross beam 11121 and the front wall longitudinal beam 11122, the second surface 111212 of the front wall cross beam 11121 extends horizontally to above the first surface 111211 of the front wall longitudinal beam 11122 and abuts against the second surface 111212 of the front wall longitudinal beam 11122 and is welded and fixed, and the first surface 111211 of the front wall cross beam 11121 extends horizontally to the edge of the second surface 111212 of the front wall longitudinal beam 11122 and abuts and is welded and fixed; the L-shaped angle iron openings of the two groups of front wall cross beams 11121 are arranged opposite to each other to further improve the connection strength. The transverse reinforcement beam 11123 is located at the bottom of the front wall main board 1111 and extends along the length direction of the front wall main board 1111 and is set throughout the length, which is used to connect with the chassis, and at the same time prevent the front wall reinforcement plate 1113 from being deformed after being assembled and welded with the outer interface of the driver's cab, and prevent the front wall component 11 from being deformed after welding; it can be understood that the transverse ends of the transverse reinforcement beam 11123 also have adjustment amounts, such as a 1.5-3.5mm gap, and a transverse reinforcement beam 11123 with smaller rigidity is set on the inner plate surface of the front wall 111 to cooperate with the chassis, and a process adjustment amount is set at the transverse reinforcement beam 11123 to ensure the overall outline and size of the driver's cab after assembly, and can simultaneously realize load and shaping, and can realize a lightweight setting of the driver's cab.

[0126] The front wall reinforcement plate 1113 is arranged along the outer contour of the front wall main plate 1111. An opening and closing mechanism mounting interface 11131 and a head cover mounting interface 11132 are provided on the front wall reinforcement plate 1113. The opening and closing mechanism mounting interfaces 11131 are arranged in two groups, each group including two opening and closing mechanism mounting interfaces 11131. The two groups of opening and closing mechanism mounting interfaces 11131 are symmetrically arranged on both sides of the transverse centerline of the front wall component 11. The opening and closing mechanism mounting interfaces can be configured as mounting seats; the head cover mounting interfaces 11132 can be configured as oblong holes to provide installation adjustment. Adhesive is used to seal the front wall 111 and the opening and closing mechanism (mechanical connection and sealing). The outer contour of the front wall 111 is recessed inward from the outer contour of the opening and closing mechanism, leaving space for adhesive application. The front wall reinforcement plate 1113 provides support for adhesive application.

[0127] The driver's cab steel structure 10 provided in this application also includes an energy-absorbing beam 15, an anti-collision column 16 and an anti-collision corner column 17; the waist beam component 14 includes a transverse waist beam 141 and a longitudinal waist beam 142, the transverse waist beam 141 is located below the front window frame of the driver's cab; the longitudinal waist beam 142 is located below the side wall window; the energy absorption area is formed by the front wall component 11, the waist beam component 14, the energy-absorbing beam 15, the anti-collision column 16 and the anti-collision corner column 17 to ensure the safety of the driver; the anti-collision column 16, the anti-collision corner column 17, the transverse waist beam 141 and the longitudinal waist beam 142 form a protective belt to further protect the driver's personal safety.

[0128] Specifically, one end of the energy-absorbing beam 15 in the longitudinal direction is fixedly connected to the front wall 111, and the other end of the energy-absorbing beam 15 in the longitudinal direction is fixedly connected to the anti-collision column 16; the anti-collision column 16 and the energy-absorbing beam 15 are arranged in a one-to-one correspondence; the anti-collision column 16 and the anti-collision corner column 17 are both fixedly arranged below the transverse waist beam 141, and the anti-collision corner column 17 is located on the outside of the anti-collision column 16 in the transverse direction.

[0129] One end of the energy-absorbing beam 15 in the longitudinal direction is connected to the front wall reinforcement plate 1113, preferably opposite the opening and closing structure mounting interface. The other end of the energy-absorbing beam 15 in the longitudinal direction is welded to the anti-collision column 16. The anti-collision column 16 and the anti-rotation corner post are both box-beam structures. In the transverse direction of the driver's cab, the anti-collision corner post 17 is located laterally outside the anti-collision column 16. Optionally, there are two energy-absorbing beams 15, two anti-collision columns 16, and two anti-collision corner posts 17. In order to ensure the structural reliability and lightweight setting of the above-mentioned protective belt, a number of vertically arranged transverse ribs 161 are set inside the anti-collision column 16 and the anti-collision corner column 17, and the transverse ribs 161 in the same row of each anti-collision column 16 and anti-collision corner column 17 are in the same horizontal plane; taking the anti-collision column 16 and the anti-collision corner column 17 as an example to illustrate that four transverse ribs 161 are set respectively, the first row of transverse ribs 161 of the anti-collision column 16 and the first row of transverse ribs 161 of the anti-collision corner column 17 are in the same horizontal plane, the second row of transverse ribs 161 of the anti-collision column 16 and the second row of transverse ribs 161 of the anti-collision corner column 17 are in the same horizontal plane, and so on.

[0130] In order to further ensure the structural reliability of the protective belt, vertical ribs 1411 corresponding to the lateral side panels of the anti-collision column 16 and the anti-collision corner column 17 are provided in the transverse waist beam 141, and a number of vertical ribs 1411 are provided in the length direction of the transverse waist beam 141. The two lateral side panels of each anti-collision column 16 are respectively provided with two vertical ribs 1411 opposite to each other. Similarly, the two lateral side panels of each anti-collision corner column 17 are respectively provided with two vertical ribs 1411 opposite to each other, so as to improve the connection strength and ensure the continuous transmission of the load.

[0131] At the same time, since the bottom collides first when a collision occurs and the bottom bears a larger load, a connecting rib 162 is provided between the bottoms of adjacent anti-collision columns 16 and anti-collision corner columns 17 to facilitate structural stability and load transfer.

[0132] Example 2

[0133] like Figure 16-24 As shown, Figure 16 A schematic diagram of the structure of the side wall provided in an embodiment of the present application; Figure 17 A schematic structural diagram of a sidewall structure provided in another embodiment of the present application; Figure 18 for Figure 17 AA cross-sectional structural diagram; Figure 19 for Figure 17 BB-direction cross-sectional structural diagram; Figure 20 Schematic diagram of the assembly of the front wall and side wall components provided in an embodiment of the present application; Figure 21 for Figure 20 A schematic diagram of the partially enlarged structure at center A; Figure 22 A schematic diagram of the lateral structure of the driver's cab steel structure provided in an embodiment of the present application; Figure 23 A schematic diagram of the assembly structure of the rear end wall and end columns provided in an embodiment of the present application; Figure 24 for Figure 23 A magnified schematic diagram of the local structure.

[0134] The side wall component 13 of the present application provides an installation interface for corner windows, side windows, and a driver's cab installed driver's station; the side wall component 13 includes a side wall frame 131 and a side wall skin 132 located on the outside of the side wall frame 131; the side wall frame 131 matches the inner contour of the side wall skin 132, and the skin needs to have good deformation ability and a certain degree of rigidity, so the plate thickness is relatively thin, generally 2 to 3 mm; the side wall frame 131 plays the role of transferring loads, and the skin plays the role of shaping and providing an installation interface, so the plate thickness is relatively thicker than the skin.

[0135] Optionally, the side wall frame 131 includes a side wall bent beam 1311 and an end column 1312. The side wall bent beam 1311 extends longitudinally and its height increases gradually from front to back. With the front direction of the rail vehicle as the front, the front end of the side wall bent beam 1311 is docked with the front wall reinforcement plate 1113 to realize the connection between the side wall component 13 and the front wall component 11; the end column 1312 is located at the longitudinal rear end of the side wall bent beam 1311 and is arranged in the vertical direction; the end column 1312 is used to connect the rear end wall component 12; the longitudinal waist beam 142 of the waist beam component 14 is located below the side wall window, the longitudinal front end of the longitudinal waist beam 142 is fixed to the side wall bent beam 1311, and the longitudinal rear end of the longitudinal waist beam 142 is perpendicular to and fixed to the end column 1312. The upper and lower planes of the longitudinal waist beam 142 are parallel to the rail surface and can serve as a positioning reference in the vehicle height direction. The longitudinal end surfaces of the end columns 1312 are perpendicular to the rail surface and can serve as a positioning reference in the vehicle length direction when the cab side walls 13 and the cab are assembled. Together with the longitudinal waist beam 142, they form a reference for the manufacture of side windows and corner windows, thereby helping to ensure that the manufacturing tolerances of the side window and corner window frames are within the limits. Preferably, the end columns 1312 are U-shaped columns.

[0136] Furthermore, the side wall frame 131 also includes:

[0137] Several support beams 1313 are arranged longitudinally. The top of the first support beam 1313 is fixed to the side wall curved beam 1311. The tops of the remaining support beams 1313 except the first support beam 1313 are fixed to the longitudinal waist beam 142. The bottom ends of the support beams 1313 are used to be fixed to the base frame.

[0138] The side wall curved beam 1311 below the longitudinal waist beam 142, the first longitudinal support beam 1313 and the longitudinal waist beam 142 form a first side wall region, in which a plurality of grid beam structures 1314 staggered in both horizontal and vertical directions are provided;

[0139] The longitudinal waist beam 142, the first longitudinal support beam 1313 below the longitudinal waist beam 142, and the end columns 1312 form a second side wall area;

[0140] The side wall curved beam 1311 above the longitudinal waist beam 142, the first longitudinal support beam 1313, the longitudinal waist beam 142 and the end column 1312 form a third side wall area, which is used to install corner windows and side windows.

[0141] The first support beam 1313 arranged from front to back in the longitudinal direction is divided into two parts, upper and lower, through the longitudinal waist beam 142. The top of the upper part of the first support beam 1313 is fixed to the side wall curved beam 1311, and the bottom of the upper part of the first support beam 1313 is fixed to the upper surface of the longitudinal waist beam 142; the top of the lower part of the first support beam 1313 is fixed to the lower surface of the longitudinal waist beam 142, and the bottom of the lower part of the first support beam 1313 is fixed to the bottom frame. The top of each of the remaining support beams 1313 is fixed to the lower surface of the longitudinal waist beam 142, and the bottom of each support beam 1313 is fixed to the bottom frame; the support beam is set to a U-shaped structure, such as Figure 19 shown.

[0142] The first side wall region consists of a longitudinal waist beam 142, a side wall curved beam 1311 below the longitudinal waist beam 142, and the lower portion of the first support beam 1313. This region is located outside the driver's cab safety zone and provides an interface for hood installation. The curvature of the side wall skin 132 in this region varies significantly. Therefore, a rigid U-shaped frame is used around the side wall skeleton 131 in this region (except for the open structure at the bottom where it connects to the chassis). Several grid beam structures 1314 are arranged in a staggered pattern, horizontally and vertically, within the first side wall region. This utilizes an orthogonal grid beam structure, i.e., thinner, denser, and shorter vertical and horizontal grid beam structures 1314. This facilitates shaping while ensuring strength and rigidity. The orthogonal grid beams in this region are 3mm thick and spaced 200 to 300mm apart. Some cross beams of the grid beam structure 1314 and the front ends of the side wall curved beams 1311 are fixed to the front wall reinforcement plate 1113; the grid beam adopts L-shaped angle iron or U-shaped angle iron, which is fixed to the front wall reinforcement plate 1113 of the driver's cab in an open structure to increase stability and reduce noise.

[0143] The second side wall area is composed of the longitudinal waist beam 142, the lower part of the first support beam 1313 and the end column 1312, forming a box-shaped stable structure for load transfer; the side wall frame 131 also includes:

[0144] A plurality of transverse reinforcement beams 1317 are respectively located between adjacent support beams 1313 and between support beams 1313 and end columns 1312 . The transverse reinforcement beams 1317 are used to support the side wall skin 132 .

[0145] A reinforcing plate 1318 is provided below any supporting beam 1313 , and the supporting beam 1313 is fixed to the base frame via the reinforcing plate 1318 .

[0146] Similar to the first side wall area, the bottom of the second side wall area is an open structure. Due to the small curvature variation in this area, and considering the requirements for shape and weight reduction, transverse reinforcement beams 1317 are used between each support beam 1313 to support the side wall skin 132. The spacing between each support beam 1313 is set at 600-700mm to meet the requirements for shape and weight reduction. The transverse reinforcement beams 1317 are vertically spaced at 250-300mm. Specifically, several transverse reinforcement beams 1317 are respectively located between adjacent support beams 1313, and between support beams 1313 and end columns 1312. At the same time, a reinforcement plate 1318 is provided below each support beam 1313, and the support beam 1313 is fixed to the base frame via the reinforcement plate 1318 to reduce stress concentration. The transverse reinforcement beams 1317 are configured as L-shaped angle irons.

[0147] Furthermore, the side wall frame 131 also includes a number of side wall patches 1319, which are located at the longitudinal front end of the grid beam structure 1314, specifically arranged in the front end grid of the grid beam structure 1314; the side wall bent beam 1311 and part of the side wall patches 1319 are fixed to the front wall component 11, and before the front end open structure of the front wall component 11 is connected with the front wall reinforcement plate 1113, the side wall patches 1319 are welded first, and the side wall patches 1319 and the front wall reinforcement plate 1113 in the outer contour area of the front wall component 11 constitute the bonding area between the opening and closing mechanism and the driver's cab; at the same time, the surface quality control of the side wall shape is further improved, the stability of the structure is enhanced, and vibration and noise are reduced.

[0148] Considering the manufacturing cost and processability, the side wall is usually welded with multiple side wall skins 132 and side wall frames 131. In order to control the deformation of the side wall skins 132 after welding, the dividing lines between the multiple side walls are set on a supporting frame, such as a longitudinal waist beam 142, a support beam 1313, etc. At the same time, corresponding support pads 13131 can be set on the support beam to improve the support of the side wall skin, such as Figure 18 shown.

[0149] The third sidewall region provides installation interfaces for corner windows and side windows, specifically including corner window installation interface 1315 and side window installation interface 1316. The top portion provides an interface for hood installation. The structural design of this region should facilitate the installation of corner windows, side windows, and hoods, minimizing error accumulation. The first, second, and third sidewall regions are formed from integral components such as the longitudinal waist beam 142 and end columns 1312, which helps reduce manufacturing errors in the connection between the second and third sidewall regions. The U-shaped beams of the end columns 1312 have two surfaces perpendicular to the rail surface, serving as a vehicle-length positioning reference for cab sidewall assembly 13 and cab assembly. The upper and lower planes of the longitudinal waist beam 142 (parallel to the rail surface) serve as a vehicle-height positioning reference for the third sidewall region. Together with the end columns 1312, they form a reference for manufacturing the side windows and corner windows, helping to minimize manufacturing errors in the side window and corner window frames. The curved side beam 1311 at the top of the third side wall provides an interface for hood installation, and is designed to be divided into sections by the longitudinal waist beam 142 and the curved side beam 1311 of the first side wall. The design of the internal beams in the first side wall area, located near the front of the vehicle, must balance load transfer and load distribution. The beam row design matches the cross-section of the U-shaped beam row in the corresponding position in the first side wall area. The beam row between the corner windows and side windows is designed to take into account the contours of the corner windows and side windows.

[0150] The side wall component 13 is a curved component, using the integral end column 1312 as the reference for vehicle length, and the integral longitudinal waist beam 142 as the reference for side wall height. This reduces the cumulative manufacturing errors after the installation of the corner window and side window frames, facilitates the subsequent installation of interior decoration, corner windows, side windows, and the driver's platform, and saves assembly and repair work. The end column 1312 is a U-shaped column, and its outer contour matches the driver's cab side wall skin. It has good rigidity and is not easily deformed, which helps to maintain the contour of the driver's cab after the side wall component 13 is connected to the rear end wall. Ribs are installed at the corresponding positions where the end column 1312 connects to the side wall curved beam 1311 and the longitudinal waist beam 142 to facilitate load transfer.

[0151] Example 3

[0152] like Figures 25-28 As shown, Figure 25 A schematic structural diagram of the rear end wall provided in an embodiment of the present application; Figure 26 This is an enlarged schematic diagram of the local structure of the top curved beam provided in an embodiment of the present application; Figure 27 A schematic diagram of the assembly structure of the cab head cover and end columns provided in an embodiment of the present application; Figure 28 Schematic diagram of the assembly structure of the end column and the passenger compartment provided in an embodiment of the present application.

[0153] The rear end wall assembly 12 provided in this application is a planar structure used to connect the driver's cab and the passenger compartment. The rear end wall assembly 12 includes a top curved beam 121 and a rear end wall frame 122. The top curved beam 121 spans the upper portion of the rear end wall frame 122 in the transverse direction, and the bottom surfaces of the lateral ends of the top curved beam 121 are seated on the top surfaces of the end columns 1312. The top curved beam 121 is used to connect the driver's cab hood 20 and the passenger compartment roof structure. The top curved beam 121 is welded and fixed to the rear end wall frame 122. The top curved beam 121 also provides a connection interface between the driver's cab hood 20 and the passenger compartment roof structure, and is connected to the side wall end columns 1312. To facilitate measurement and assembly positioning during the driver's cab assembly, the interface between the top curved beam 121 and the end columns 1312 is parallel to the rail surface.

[0154] Optionally, the rear wall frame 122 includes:

[0155] The rear end wall door frame 123 has a center line that coincides with or is parallel to the transverse center line of the cab steel structure 10; the bottom of the rear end wall door frame 123 is used to connect to the chassis;

[0156] A plurality of rear end wall cross beams 124 and door frame columns on both sides of the rear end wall door frame 123 are connected to the end columns 1312 via the plurality of rear end wall cross beams 124 .

[0157] The rear wall door frame 123 has two door frame columns arranged in a transversely opposed relationship. The bottom of the rear wall door frame 123 is used to connect to the chassis. The rear wall crossbeam 124 is preferably configured as an L-shaped or U-shaped angle iron. This is open during the rear wall assembly process to provide a process margin, ensuring the installation accuracy of the door frame structure. This also facilitates the connection of the cab side walls to the rear wall assembly 12 by grinding the length of the rear wall crossbeam 124 to ensure the required overall cab profile accuracy. Similarly, the bottom column of the rear wall door frame 123 is also configured as an open structure, such as an L-shaped or U-shaped structure. This open structure connects to the chassis floor surface, facilitating height adjustment by reducing the connection area.

[0158] Optionally, a head cover end interface 1211 is provided at one end of the top curved beam 121 along the longitudinal direction toward the cab head cover 20;

[0159] And / or, a passenger compartment top area interface 1212 is provided on a side of the top surface of the top curved beam 121 close to the passenger compartment.

[0160] The end interface 1211 of the hood is a stepped structure, and the end of the cab hood 20 is also set to a stepped structure accordingly to achieve docking and fixation by bonding. The top surface of the top curved beam 121 is provided with a passenger compartment top area interface 1212, which can be set as a groove, and the passenger compartment top area can be overlapped with the passenger compartment skin. It can be understood that after the driver's cab is assembled, the passenger compartment roof skin is overlapped on the top curved beam 121 to ensure the welding quality and the airtightness of the whole vehicle. The passenger compartment roof assembly is the last component to be assembled during the vehicle body assembly. After ensuring the airtightness of the roof skin and the rear end wall of the driver's cab, in order to reduce the repair and adjustment work, a connecting plate is set between the passenger compartment roof frame and the top curved beam 121 of the rear end wall of the driver's cab to adjust the manufacturing error during the vehicle body assembly to ensure the vehicle body length.

[0161] At the same time, in order to achieve the connection between the end column 1312 and the passenger compartment and the driver's cab, the end column 1312 is provided with a mounting flange 13121 extending toward the passenger compartment side along the longitudinal direction. The connecting seam between the passenger compartment side wall skin 21132 and the driver's cab side wall skin 132 is butted against the mounting flange 13121.

[0162] The side wall frame 22 of the passenger compartment extends longitudinally to the inner surface of the mounting flange 13121 and butts against the longitudinal end wall of the end column 1312 .

[0163] The installation flange 13121 can be specifically an L-shaped angle iron, one side of the L-shaped angle iron is in contact with the longitudinal end wall of the end column 1312, and the other side of the L-shaped angle iron extends longitudinally toward the passenger compartment. The connection seam between the passenger compartment side wall skin 21 and the driver compartment side wall skin 132 overlaps the installation flange 13121, and the end column 1312 provides support for the passenger compartment side wall skin 132 and the driver compartment side wall skin 132 at the same time, ensuring the welding quality and the airtightness of the entire vehicle. The passenger compartment frame and the end column 1312 of the driver compartment side wall assembly 13 are connected through the reserved process adjustment amount of the passenger compartment frame to ensure the length of the vehicle body. The passenger compartment side wall skin 132 and the driver compartment end column 1312, the passenger compartment roof skin and the top curved beam 121 adopt an overlapping structure, which is conducive to ensuring the welding quality, the dimensional accuracy after the vehicle body is assembled, and the airtightness of the entire vehicle.

[0164] In one specific embodiment, after the driver's cab is assembled, its structure with the chassis includes interfaces with the front wall 11, the side walls 13, and the rear wall 12. Due to the high overall rigidity of the chassis, a transverse reinforcement beam 11123 with low rigidity is installed on the inside of the front wall of the driver's cab to connect with it, ensuring the dimensional accuracy and airtightness of the vehicle body after assembly. The side wall frame 131 is connected to the chassis plane via an open support beam 1313, and the side wall skin 132 is overlapped on the support beam 1313, ensuring not only an aesthetically pleasing appearance after welding but also the airtightness of the vehicle.

[0165] The above-described cab is suitable for structures with carbon steel bodies and a relatively large interior cab space requirement. It utilizes a bottom cab steel structure 10 combined with an upper cab hood 20. The bottom cab steel structure 10, comprised of a carbon steel metal frame and skin, ensures load-bearing and shape stability, ensuring driver safety. It also provides mounting ports for cab equipment such as side windows and movable windows, minimizing interior cab space occupation and ensuring convenient operating space throughout the cab. The reduced size of the cab steel structure 10 reduces manufacturing costs for molds, gauges, and bent parts, improving economic efficiency and achieving a lightweight design.

[0166] The upper cab hood 20 utilizes a fiberglass sandwich structure that facilitates curved surface shaping, providing a three-dimensional interface for the windshield, exterior lighting, and headlight glass. This achieves lightweight design while reducing manufacturing costs. Furthermore, the fiberglass composite manufacturing process improves the dimensional accuracy of the three-dimensional components and the control of interface matching. The cab hood 20 is bolted together for reliable connection, and a sealant seal is used to seal the cab steel structure 10 and the cab hood 20.

[0167] The connection interfaces between the driver's cab front wall component 11, the side wall component 13, and the rear end wall component 12 adopt a connection structure with high stiffness matching low stiffness, and process adjustment amounts are set in the area with low stiffness, which is conducive to ensuring the overall outline and size of the driver's cab after assembly.

[0168] The design of the connection interfaces between the front wall, side walls and rear end wall of the driver's cab, as well as the interface relationship design between the driver's cab steel structure 10 and the passenger compartment chassis, side walls and roof, can reduce the amount of assembly mold modification, control post-weld deformation, and ensure the dimensional accuracy and sealing of the entire vehicle.
