Description

Technical Field

[0001] This utility model relates to the field of vehicle structure technology, specifically to an integrated front compartment structure. Background Technology

[0002] Heavy-duty vehicles, such as electric heavy-duty trucks, typically have a variety of components in their front compartment, including steering components, braking components, thermal management components, high-voltage boxes, and low-voltage controllers. They also contain numerous high-voltage and low-voltage wiring harnesses.

[0003] In related technologies, various components of the front compartment are often fixed separately to the chassis. The actual installation process is complicated and requires a complex installation sequence, which is time-consuming and labor-intensive. Furthermore, during the actual installation process, the installation space for the front compartment components is very limited due to the influence of the components connected in the preceding processes such as the chassis and steering axle. This greatly prolongs the installation time on the production line, increases the difficulty of installation, and affects the efficiency of installation. Utility Model Content

[0004] In view of this, the present invention provides an integrated front compartment structure to solve the problems of complex, time-consuming and labor-intensive, long installation time and high installation difficulty of front compartment components.

[0005] This utility model provides an integrated front cabin structure connected to a vehicle frame, including a bracket and functional components connected to the bracket; the bracket includes a first crossbeam, a second crossbeam, and a third crossbeam; wherein the first crossbeam, the second crossbeam, and the third crossbeam are stacked sequentially and spaced apart, the first crossbeam and the second crossbeam are connected by a first vertical beam, and the second crossbeam and the third crossbeam are connected by a second vertical beam; wherein the first crossbeam and the first vertical beam constitute a first mounting part, and the second crossbeam and the second vertical beam constitute a second mounting part; a connecting part is provided on the bracket; a first pre-installation frame is provided on the vehicle frame, and the first pre-installation frame is connected to the connecting part, so that the integrated front cabin structure is connected to the vehicle frame.

[0006] Beneficial effects: By setting up a layered bracket system, including but not limited to a first crossbeam, a second crossbeam, and a third crossbeam, with adjacent crossbeams connected by vertical beams (the first and second vertical beams), the first crossbeam and the first vertical beam form the lower mounting position (first mounting part), the second crossbeam and the second vertical beam form the middle mounting position (second mounting part), and the third crossbeam serves as the upper mounting position. This creates a multi-layered bracket structure, enabling the unified offline installation of the front compartment functional components directly onto the brackets. During assembly on the vehicle assembly line, i.e., during vehicle loading, the integrated front compartment structure (front compartment functional components) can be directly installed. The components are integrated and mounted on a bracket, and then placed into the vehicle body. The components are connected to the bracket and the first pre-mounted bracket on the frame via a connecting part. This eliminates the need to install multiple front compartment components individually, greatly simplifying the vehicle assembly process and eliminating complex assembly procedures. This significantly shortens the assembly time on the final assembly line, saving time and effort. The integrated mounting of the front compartment components on the bracket greatly reduces the space occupied by the front compartment structure. Furthermore, due to the integrated mounting of the front compartment components, only a single space needs to be left at the installation location during vehicle assembly. This eliminates the influence of previous processes on the vehicle assembly line (such as the mounting of the steering axle and the frame), greatly reducing the difficulty of vehicle assembly and improving the time and efficiency of vehicle assembly.

[0007] In one alternative embodiment, the first crossbeam, the second crossbeam, and the third crossbeam are arranged in parallel and spaced apart in the vertical direction; wherein at least a portion of the frame of the second crossbeam extends to the outside of the orthographic projection of the third crossbeam in the vertical direction.

[0008] Beneficial effects: By extending part of the second crossbeam outwards from the orthographic projection of the third crossbeam, at least part of the second crossbeam does not overlap with the third crossbeam in the vertical direction. This creates an additional independent installation area at the second crossbeam within the limited vertical space, which can accommodate large-sized front cabin components, avoiding the space limitations of traditional stacking structures and making it highly practical.

[0009] In one alternative embodiment, the first crossbeam, the second crossbeam, and the third crossbeam are each composed of multiple support beams connected to each other at a preset angle.

[0010] In one alternative embodiment, the second crossbeam includes at least two unit frames, the support beams of the at least two unit frames being detachably connected.

[0013] In one alternative embodiment, the connecting portion is located at the second crossbeam, and the third plate is connected to the support beam at the second crossbeam.

[0014] In one optional embodiment, the second plate is provided with a first positioning part, and the fourth plate is provided with a second positioning part. When the first pre-assembly frame cooperates with the connecting part, the first positioning part and the second positioning part cooperate to position the frame.

[0015] In one optional embodiment, it further includes a second pre-mounted frame connected to the lower wing plate of the vehicle frame; the second pre-mounted frame includes a connecting plate and a bending plate; the bending plate has a fifth plate and a sixth plate, the fifth plate and the sixth plate being connected at a preset angle; wherein the connecting plate and the fifth plate are respectively disposed on opposite sides of the lower wing plate and connected to the lower wing plate by means of fasteners; the sixth plate is connected to the vertical beam so that the bracket is connected to the vehicle frame.

[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0025] According to an embodiment of the present invention, an integrated front cabin structure is provided, comprising: a bracket 1 and functional components connected to the bracket 1; the bracket 1 includes a first crossbeam 11, a second crossbeam 12, and a third crossbeam 13; wherein the first crossbeam 11, the second crossbeam 12, and the third crossbeam 13 are stacked sequentially and spaced apart, the first crossbeam 11 and the second crossbeam 12 are connected by a first vertical beam 111, and the second crossbeam 12 and the third crossbeam 13 are connected by a second vertical beam 121; wherein the first crossbeam 11 and the first vertical beam 111 constitute a first mounting part, and the second crossbeam 12 and the second vertical beam 121 constitute a second mounting part; a connecting part 2 is provided on the bracket 1; a first pre-installation frame 3 is provided on the vehicle frame 5, and the first pre-installation frame 3 is connected to the connecting part 2, thereby connecting the integrated front cabin structure to the vehicle frame 5.

[0026] Combination Figures 1 to 3As shown, the integrated front compartment structure is an integrated module, which is assembled offline from the bracket 1 and the front compartment functional components. Offline means that before the formal assembly on the main production line, the production personnel complete the modular integration and installation of the bracket 1 and the front compartment functional components in the pre-assembly workshop. During the formal assembly on the main production line, that is, when loading the vehicle, the integrated module is installed. The connecting part 2 at the integrated module is connected to the first pre-assembly frame 3 at the frame 5 with fasteners. Then, the pipelines at the front compartment functional components are connected to the main oil circuit and the main electrical system at the frame 5 in sequence. Compared with the traditional bulk assembly method, the modular assembly method reduces the assembly time on the main production line by 60% or more. In actual production, the front compartment assembly time of a single vehicle can be reduced from 45 minutes to 18 minutes, which significantly improves the capacity utilization rate.

[0027] The integrated front compartment structure provided in this embodiment uses a layered bracket 1, including but not limited to a first crossbeam 11, a second crossbeam 12, and a third crossbeam 13. Adjacent crossbeams are connected by vertical beams (a first vertical beam 111 and a second vertical beam 121). The first crossbeam 11 and the first vertical beam 111 form the lower mounting position (first mounting part), the second crossbeam 12 and the second vertical beam 121 form the middle mounting position (second mounting part), and the third crossbeam 13 serves as the upper mounting position. This forms a multi-layered bracket 1 structure, achieving the goal of directly mounting the functional components of the front compartment to the bracket 1 offline. During assembly on the vehicle assembly line, i.e., during vehicle loading, it can... The integrated front compartment structure (with front compartment functional components integrated and mounted on bracket 1) is directly placed into the vehicle body and connected to the first pre-mounted bracket 3 at the frame 5 via connecting part 2. This eliminates the need to install multiple front compartment components individually, greatly simplifying the vehicle assembly process and eliminating complex assembly procedures. This significantly shortens the assembly time on the final assembly line, saving time and effort. The integrated placement of the front compartment components on bracket 1 greatly reduces the space occupied by the front compartment structure. Furthermore, due to the integrated placement of the front compartment components, only a single space needs to be left at the installation location during vehicle assembly. This eliminates the impact of previous processes on the vehicle assembly line (such as the installation of the steering axle and frame 5), greatly reducing the difficulty of vehicle assembly and improving assembly time and efficiency.

[0028] In some embodiments, the first crossbeam 11, the second crossbeam 12, and the third crossbeam 13 are arranged in parallel and spaced apart in the vertical direction; wherein at least a portion of the frame of the second crossbeam 12 extends to the outside of the orthographic projection of the third crossbeam 13 in the vertical direction.

[0029] Combination Figure 1As shown, at least a portion of the second crossbeam 12 extends to the outside of the vertical projection of the third crossbeam 13, meaning that at least a portion of the second crossbeam 12 does not overlap with the third crossbeam 13 in the vertical direction. This means that the second crossbeam 12 is exposed relative to the third crossbeam 13. Since the exposed portion of the second crossbeam 12 is not obstructed by the third crossbeam 13 above it, it is convenient to install large front cabin components at the exposed portion of the second crossbeam 12, thus meeting the installation requirements.

[0030] In this embodiment, by extending a portion of the second crossbeam 12 outwards from the orthographic projection of the third crossbeam 13, at least a portion of the second crossbeam 12 does not overlap with the third crossbeam 13 in the vertical direction. This creates an additional independent installation area at the second crossbeam 12 within a limited vertical space, thereby accommodating and installing large-sized front cabin components. This avoids the space limitations of traditional stacking structures and is highly practical.

[0031] In some embodiments, the first crossbeam 11, the second crossbeam 12, and the third crossbeam 13 are each composed of multiple support beams 14 connected to each other at a predetermined angle.

[0032] Combination Figure 1 As shown, the crossbeams (first crossbeam 11, second crossbeam 12, and third crossbeam 13) can be formed by connecting multiple support beams 14 at a preset angle. The support beams 14 can be divided into horizontal beams and vertical beams. Multiple horizontal beams and multiple vertical beams are connected perpendicularly to form the crossbeams. The specific structural forms of the first crossbeam 11, second crossbeam 12, and third crossbeam 13 are not limited, that is, the number of support beams 14 and their interconnection positions are not limited, so that the crossbeams (first crossbeam 11, second crossbeam 12, and third crossbeam 13) can meet the function of supporting installation and can bear functional components.

[0033] In some embodiments, the second crossbeam 12 includes at least two unit frames 122, and the support beams 14 of the at least two unit frames 122 are detachably connected.

[0034] Combination Figure 1 As shown, the frame of the second crossbeam 12 is segmented, that is, the second crossbeam 12 includes at least two unit frames 122, and the ends of the support beams 14 of the at least two unit frames 122 are detachably connected, which facilitates the disassembly and maintenance of the subsequent front cabin components in actual application. If the second crossbeam 12 is an integral component, the functional components installed at the first mounting part (first crossbeam 11 and first vertical beam 111) are difficult to disassemble and maintain, and can only be disassembled from the side of the bracket 1. By making the frame of the second crossbeam 12 segmented, when the functional components at the first mounting part need to be repaired or replaced, the corresponding unit frame 122 can be disassembled to more conveniently disassemble and install the functional components of the first mounting part.

[0035] In some embodiments, the cross-sectional shape of the first vertical beam 111 and the second vertical beam 121 is C-shaped.

[0036] Specifically, the vertical beams (first vertical beam 111 and second vertical beam 121) include a web and flanges connected to opposite sides of the web, so that the cross-sectional shape of the vertical beams is C-shaped, in order to improve the bending load capacity of the vertical beams, improve the structural strength of the support 1, and enable the support 1 to bear the weight of the front cabin functional components, thus ensuring the overall stability of the integrated front cabin structure.

[0037] In some embodiments, the first pre-mounted frame 3 has a first plate 31 and a second plate 32, the first plate 31 is fixed to the vehicle frame 5, and the second plate 32 is connected to the first plate 31 at a preset angle; the connecting part 2 has a third plate 21 and a fourth plate 22, the third plate 21 is fixed to the bracket 1, and the fourth plate 22 is connected to the third plate 21 at a preset angle; wherein, when the integrated front compartment structure is connected to the vehicle frame 5, the second plate 32 and the fourth plate 22 abut against each other, and the second plate 32 and the fourth plate 22 are fixed by means of fasteners.

[0038] Combination Figures 1 to 3 As shown, when the integrated front compartment structure is assembled with the frame 5, the first pre-mounted frame 3 serves as the connection point, and the connecting part 2 cooperates with the first pre-mounted frame 3; the first plate 31 and the second plate 32 of the first pre-mounted frame 3 may be connected vertically, but not limited to the same direction; the third plate 21 and the fourth plate 22 of the connecting part 2 may be connected vertically, but not limited to the same direction; the third plate 21 is connected to the frame; and the fourth plate 22 extends away from the frame relative to the third plate 21.

[0039] Specifically, the fourth plate 22 is perpendicular to the vertical direction. When the integrated front compartment structure is installed, the installation refers to the use of mechanical hoisting equipment to vertically lower the pre-installed integrated module (integrated front compartment structure) and align it with the preset installation position on the frame 5. When the integrated module is lowered to the preset installation position, the fourth plate 22 of the connecting part 2 abuts against the second plate 32 of the first pre-installed frame 3. The operator uses fasteners to connect and fix the second plate 32 and the fourth plate 22 together. The fasteners can be bolts.

[0040] Optionally, mounting holes are provided at corresponding positions on the second plate 32 and the fourth plate 22. During connection, fasteners pass through the mounting holes of the fourth plate 22 and the second plate 32 in sequence and are tightened and fixed.

[0041] Optionally, the shape of the first plate 31 is not limited, as long as it can be connected to the frame 5.

[0042] Optionally, the first pre-assembly frame 3 also includes a seventh plate 33 and an eighth plate 34, combined with Figure 3As shown, the first plate 31 is perpendicularly connected to the second plate 32, the seventh plate 33 is connected between the first plate 31 and the second plate 32, and the seventh plate 33 is perpendicularly connected to the first plate 31 and the second plate 32 respectively, so that the seventh plate 33, the first plate 31 and the second plate 32 form a notch; the eighth plate 34 is connected to the end of the seventh plate 33 away from the second plate 32, and the eighth plate 34 is perpendicularly connected to the seventh plate 33, so that the eighth plate 34 is parallel to the second plate 32.

[0043] Optionally, the eighth plate 34 of the first pre-mounted frame 3 is connected to the upper wing plate 52 of the frame 5 by means of a bolt assembly to improve the connection strength between the first pre-mounted frame 3 and the frame 5.

[0044] Optionally, the first side panel of the second plate 32 abuts against the fourth plate 22, and a pre-installed nut 10 is welded to the second side panel. The pre-installed nut 10 is installed before the integrated module is installed. Figures 1 to 3 As shown, since the first plate 31 is connected to the second plate 32 and the first plate 31 is fixed to the frame 5, when the second plate 32 abuts against the third plate 21, the first plate 31 and the fifth plate 421 surround and block the second side plate surface of the second plate 32. If a pre-installed nut 10 is not installed before the integrated module is installed, it will be difficult for the operator to manually or with tools insert into the second side plate surface of the second plate 32 to install the nut when connecting the second plate 32 and the fourth plate 22 with fasteners. Therefore, by welding the pre-installed nut 10 to the second side plate surface of the second plate 32 in advance, when the operator connects the second plate 32 and the fourth plate 22, after aligning the mounting hole, the operator inserts the bolt from the top side of the fourth plate 22 and screws the bolt into the pre-installed nut 10 (back-welded nut) on the inside with a wrench, thus avoiding the problem of no installation operation space affecting assembly after installation.

[0045] In some embodiments, the connecting part 2 is provided at the second crossbeam 12, and the third plate 21 is connected to the support beam 14 at the second crossbeam 12.

[0046] Combination Figure 1 As shown, the third plate 21 is fixed to the second crossbeam 12. The cross-sectional shape of the third plate 21 can be, but is not limited to, C-shaped. The third plate 21 includes a main plate and side edges connected to opposite sides of the main plate to improve the strength of the connecting parts 2. Multiple connecting parts 2 are spaced apart at the second crossbeam 12. The structural form of the third plate 21 is not limited, as long as it is connected to the frame. The third plate 21 can be a separate plate segment, or it can be formed by extending downward in the vertical direction from the end of the second vertical beam 121. The fourth plate 22 is perpendicular to the main plate of the third plate 21. The fourth plate 22 is connected to the third plate 21 by means of a transition plate 23. The transition plate 23 is perpendicular to the fourth plate 22, and the transition plate 23 and the fourth plate 22 are L-shaped. At the same time, the plate surface of the transition plate 23 is connected to the third plate 21, so that the fourth plate 22 is perpendicular to the third plate 21.

[0047] In some embodiments, the second plate 32 is provided with a first positioning part 321, and the fourth plate 22 is provided with a second positioning part 221. When the first pre-assembly frame 3 cooperates with the connecting part 2, the first positioning part 321 and the second positioning part 221 cooperate for positioning.

[0048] Combination Figures 1 to 3 As shown, the first positioning part 321 can be, but is not limited to, a positioning pin, and the second positioning part 221 can be, but is not limited to, a positioning hole. When the integrated module is installed, the positioning hole at the fourth plate 22 is aligned with the positioning pin to achieve the positioning function during installation.

[0049] In some embodiments, the system further includes a second pre-mounted frame 4 connected to the lower wing plate 51 of the frame 5; the second pre-mounted frame 4 includes a connecting plate 41 and a bending plate 42; the bending plate 42 has a fifth plate 421 and a sixth plate 422, the fifth plate 421 and the sixth plate 422 being connected at a preset angle; wherein the connecting plate 41 and the fifth plate 421 are respectively disposed on opposite sides of the lower wing plate 51 and connected to the lower wing plate 51 by means of fasteners; the sixth plate 422 is connected to the vertical beam so that the bracket 1 is connected to the frame 5.

[0050] It should be noted that the frame 5 has an upper wing plate 52 and a lower wing plate 51 on opposite sides. Multiple first pre-mounted frames 3 are connected to the upper wing plate 52 of the frame 5, and multiple second pre-mounted frames 4 are connected to the lower wing plate 51 of the frame 5. The upper wing plate 52 and the lower wing plate 51 are spaced apart to improve the stability of the integrated front compartment structure and the frame 5.

[0051] Combination Figures 1 to 5 As shown, the first vertical beam 111 has a through mounting hole on the side near the first horizontal frame 11, and the sixth plate 422 of the second pre-assembly frame 4 has a mounting hole; a pre-installed nut 10 is welded to the side of the first vertical beam 111 away from the sixth plate 422 and near the mounting hole to avoid the problem of no space for nut installation after the first vertical beam 111 is disengaged, which would affect the assembly; the sixth plate 422 abuts against the first vertical beam 111, and the fastener can be a bolt that passes through the mounting holes of the sixth plate 422 and the first vertical beam 111 in sequence and is then fastened to the pre-installed nut 10.

[0052] In some embodiments, the functional component includes a first module assembly 6, which is mounted on the first mounting portion; the first module assembly 6 includes a steering pump 61, an air filter 62, and an air tank 63, which are respectively connected to the first crossbeam 11; the first module assembly 6 also includes a high-pressure box 64 and a muffler 65, which are respectively connected to the first vertical beam 111; wherein the cross-sectional shape of the support beam 14 of the first crossbeam 11 connected to the steering pump 61 is C-shaped; the functional component also includes a second module assembly 7, which is mounted on the second mounting portion; the second module assembly 7 includes a thermal management unit 71, a battery 72, and a liquid storage tank 73, which are respectively connected to the second crossbeam 12; the functional component also includes a fuse box 8, which is connected to the side of the third crossbeam 13 opposite to the second crossbeam 12.

[0053] Specifically, the bracket 1 comprises three parts, from bottom to top: the first mounting part (composed of the first horizontal frame 11 and the first vertical beam 111), the second mounting part (composed of the second horizontal frame 12 and the second vertical beam 121), and the third horizontal frame 13.

[0054] Combination Figure 1 As shown, a first module assembly 6 of the front compartment functional components can be arranged at the first mounting part. The first module assembly 6 can specifically be, but is not limited to, a braking assembly. The braking assembly includes, but is not limited to, a steering pump 61, an air filter 62, and an air reservoir 63. The steering pump 61 is a steering oil pump, located on the front side of the first mounting part for easy connection to the steering gear on the front side of the vehicle. Figure 2As shown, the steering pump 61 can be installed on the left side of the first crossbeam 11. The steering gear, also known as the steering unit, is an existing component. The air filter 62 is installed on the right side of the first crossbeam 11 and is located above the first crossbeam 11. The air reservoir 63 is connected to the right side of the first crossbeam 11 and is located below the first crossbeam 11. By arranging the steering pump 61, air filter 62, and air reservoir 63 in the first mounting part, it is convenient to connect the braking assembly with the brake pipes pre-laid inside the frame 5. In addition, the braking assembly also includes a high-pressure box 64 and a muffler 65. The muffler 65 is fixed to the first vertical beam 111 and is located at the steering pump 61. Above 1, the braking assembly also includes an air compressor 66, which is located between the steering pump 61 and the muffler 65, and is connected to the steering pump 61 and the muffler 65 on both sides respectively; the high-voltage box 64 is fixed to the first vertical beam 111 by means of a crossbeam, and the high-voltage box 64 is located above the air filter 62; the crossbeam is connected to the first vertical beam 111, and the crossbeam and the first cross frame 11 are spaced apart, the high-voltage box 64 is fixed to the crossbeam and the first vertical beam 111, so that the high-voltage box 64 is fixed to the first mounting part, and there is space between the high-voltage box 64 and the first cross frame 11, which can be used to arrange cables, which can be high-voltage lines.

[0055] Optionally, the number of first vertical beams 111 can be, but is not limited to, six, and the specific number is determined according to the actual installation requirements of the front cabin components.

[0056] In this embodiment, since the steering pump 61 and air compressor 66 are relatively heavy and have a large amount of vibration during operation, the support beams 14 of the first crossbeam 11 that cooperate with the steering pump 61 and air compressor 66 are all C-shaped beams or steel pipes, thereby improving the load-bearing capacity of the beams at the corresponding positions. Since the air tank 63 is relatively light, the beams of the first crossbeam 11 that cooperate with the air outlet can be made of sheet metal parts. Sheet metal parts refer to parts made by cold working processes such as shearing, stamping, and stretching of thin metal sheets, which helps to reduce costs.

[0057] Combination Figure 1As shown, the second crossbeam 12 is segmented, consisting of at least two unit frames 122. These at least two unit frames 122 are detachably connected, facilitating subsequent maintenance of the integrated module. If a component fixed to the first mounting part needs to be repaired or replaced, only the unit frame 122 above that component needs to be removed. In addition, a second module assembly 7 is arranged at the second mounting part. The second module assembly 7 includes, but is not limited to, a thermal management unit 71, a battery 72, and a liquid storage tank 73. The battery 72 can be a storage battery 72, and the liquid storage tank 73 can be a steering oil tank. The thermal management unit 71 is relatively large and is located on the frame of the second crossbeam 12 that is not obstructed by the third crossbeam 13. The liquid storage tank 73 is connected to the second vertical beam 121 via a plate, with the plate fixed to one of the second vertical beams 121. The battery 72 is located on the frame of the second crossbeam 12 that is not obstructed by the third crossbeam 13 and is situated beside the thermal management unit 71.

[0058] Combination Figure 1 As shown, the second crossbeam 12 is provided with multiple connecting parts 2, which are connected to the first preset frame at the upper wing plate 52 of the frame 5, so that the integrated module is initially fixed to the frame 5; in addition, the second crossbeam 12 is also provided with a connecting beam 15, which is fixed to the second crossbeam 12 and extends downward in the vertical direction. The beam body of the connecting beam 15 is located in the area between the first crossbeam 11 and the second crossbeam 12. A large gap is left between the connecting beam 15 and the first module assembly 6, thereby providing operating space for the installation of fasteners. The connecting beam 15 can be directly connected to the frame 5 with the help of the L-shaped plate 16 and fasteners, without the need to set the first preset frame at the frame 5; wherein, the L-shaped plate 16 includes at least two vertically connected plates, and at least two plates are respectively connected to the connecting beam 15 and the upper wing plate 52; a fuse box 8 is installed on the side of the third crossbeam 13 away from the second crossbeam 12.

[0059] In this embodiment, the bracket 1 and the front compartment functional components it carries constitute an integrated module. The front compartment functional components include most of the components arranged in the front compartment. Therefore, after offline sub-assembly, the integrated module can be unloaded onto the vehicle frame 5 on the final assembly line, thereby greatly shortening the assembly time on the final assembly line.

[0060] Optionally, when the integrated module is assembled offline, it is installed layer by layer from bottom to top; after the functional components are fixed, the air compressor 66, silencer 65 and air filter 62 are connected in sequence through the pipeline 9.

[0061] Combination Figure 5As shown, the connection points between the integrated module and the frame 5 are located at the upper wing plate 52 and the lower wing plate 51 of the frame 5; the connecting plate 41 and the bending plate 42 of the second pre-installation frame 4 are respectively located on opposite sides of the lower wing plate 51 and are fixed by fasteners; when the second pre-installation frame 4 is pre-installed on the frame 5, the fifth plate 421 of the connecting plate 41 and the bending plate 42 are not fastened at first. After the integrated module is installed, the first vertical beam 111 and the sixth plate 422 of the connecting plate 41 are tightly attached, and then the fifth plate 421 is fastened to the connecting plate 41.

[0062] In addition, for the final assembly line, in addition to installing the first pre-assembly frame and the second pre-assembly frame at the upper wing plate 52 and the lower wing plate 51 of the frame 5 respectively, pipelines should also be laid in advance inside the frame 5. The pipelines should not extend beyond the upper and lower wing plates 51 of the frame 5 to leave the necessary space for the installation of the integrated module. After the integrated module is installed and fixed, the connectors and pipelines are connected to complete the installation of the integrated module.

[0063] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
