Description

Technical Field

[0007]

[0001] The utility model belongs to the field of pipeline, and particularly relates to an automobile pipeline layout structure and a bus. Background Art

[0002] Automobile pipeline layout structure: It is a pipeline layout structure that standardizes the main trunk direction of the pipelines on the automobile chassis and facilitates the assembly of the pipelines. When installing the pipelines on the vehicle frame, it is necessary to consider the production and installation efficiency and the reliability of the fixing structure. This requires that the pipeline layout should not only ensure the convenience of installation and few fixing positions, but also ensure that the pipelines are firmly and reliably installed, neatly and orderly after the installation of the pipelines, and have enough clearance from other assembly parts to avoid vibration and wear. As Figure 1 shown, the current vehicle pipeline layout usually arranges the main trunk of the pipelines inside the left and right longitudinal beams with an I-shaped or other cross-section, and the branch is arranged along the cross beam in a ladder-shaped fixing structure. This structure has the following disadvantages: ① Since the pipelines are arranged inside the longitudinal beams, there is interference with the cross beam and the bolt heads of the bracket. During the driving of the vehicle, there is a risk of mutual friction between the pipelines and the bolt heads, and the reliability of the pipelines is poor; ② Usually, the cross beam is drilled at the connection with the longitudinal beam to allow the pipelines to pass through. Due to the long main trunk of the pipelines, the installation efficiency of the workshop workers for piercing is low, and the pipelines are easily scratched; ③ Since different assemblies are allocated to different workstations during the workshop assembly, the installation space for the subsequent assembled pipelines will become smaller, and the assembly is very difficult; ④ Since the pipeline branches need to be fixed along the cross beam, the pipelines of each assembly will cross on the cross beam, resulting in the pipelines being repeatedly bundled at different workstations and the pipelines being intertwined with each other, affecting the aesthetics of the vehicle pipelines; ⑤ When repairing the pipelines of a certain assembly later, all the irrelevant pipelines need to be disassembled together, and the maintenance convenience is poor.

[0005] The longitudinal beams are I-shaped or C-shaped, and the inner spaces of the two longitudinal beams are arranged facing each other; the inner spaces of the longitudinal beams pass through the assemblies of at least one pipeline; all the assemblies passing through the inner spaces of the longitudinal beams and the spaces above the longitudinal beams are arranged in layers in the height direction.

[0006] All the assemblies with transverse lengths pass through and only pass through the same cross beam.

[0007] The longitudinal beam includes a vertical plate, an upper plate arranged at the upper end of the vertical plate, and a lower plate arranged at the lower end of the vertical plate; the inner spaces of the two longitudinal beams are arranged facing each other; the bolts on the longitudinal beams are reversed, and the heads of the bolts are located in the inner space of the longitudinal beams.

[0019] The following will combine the accompanying drawings and specific embodiments to clearly and completely describe the technical solution of the present invention. Figure 1-4As shown in the figure, an automotive pipeline layout structure includes two longitudinal beams 6 arranged on a vehicle frame and at least one cross beam 5 connecting the two longitudinal beams 6; a recessed position is provided on the cross beam 5, and the upper surface of the recessed position is lower than the upper surface of the longitudinal beam 6. The assembly of at least one pipeline is laid in the recessed position of the cross beam 5. Here, the recessed position can be only set in the middle position of the cross beam 5; it can also be set on all of the cross beams 5, that is, the upper surface of the entire cross beam 5 is lower than the upper surface of the longitudinal beam 6, and the cross beam 5 is recessed or sunken as a whole relative to the longitudinal beam 6. The recessed position can be continuously set on the cross beam 5, or can be set at intervals, such as in sections, on the cross beam 5. The recessed position can ensure that the upper surface of the pipeline assembly set in the recessed position of the cross beam 5 does not exceed the specified height, avoiding interference between the pipeline assembly and other components. Compared with the existing structure where several assemblies pass through the inside or the inner side of the longitudinal beam 6, in the present invention, the pipeline assembly can either pass through the inner side of the longitudinal beam 6 or be set in the recessed position of the cross beam 5. In the horizontal direction, that is, in the width direction, the position where the pipeline assembly can be laid in the present invention is wider, and the pipeline assemblies can be laid without overlapping in the horizontal direction, that is, in the width direction. The various assemblies of the pipeline do not cross each other, which is convenient for bundling during installation and disassembly during maintenance, improving the installation efficiency and maintenance efficiency of the pipeline. The pipeline assemblies are more beautiful and reliable.

[0020] Furthermore, the longitudinal beam 6 is in the shape of an I or a C, and the inner spaces of the two longitudinal beams 6 face each other; the inner space of the longitudinal beam 6 passes through the assembly of at least one pipeline; all the assemblies passing through the inner space of the longitudinal beam 6 and the space above the longitudinal beam 6 are arranged in layers in the height direction. In the space between multiple cross beams 5, the space above the longitudinal beam 6 is insufficient, and the assembly may not be set. In positions such as the front side area of the frontmost cross beam 5 and the rear side area of the rearmost cross beam 5, the space above is sufficient, and the pipeline assembly can be set both above the longitudinal beam 6 and in the inner space of the longitudinal beam 6. In the pipeline layout structure of the present invention, one end is arranged in a high-low layered manner in the vertical direction, that is, in the height direction, of the longitudinal beam 6, and the other end cooperates with the corresponding cross beam 5 structure having a recessed position, dividing channels in the horizontal direction, avoiding interference between the pipelines and the vehicle body floor, and can achieve pipeline paving, improving the installation efficiency.

[0021] Furthermore, all assemblies with transverse lengths pass through and only pass through the same crossbeam 5. Passing here refers to passing through the vicinity of the crossbeam 5, including the upper side, front side, and rear side of the crossbeam 5. In the present invention, pipelines connecting the left side parts of the vehicle are arranged on the left side, and pipelines connecting the right side parts of the vehicle are arranged on the right side. Pipelines that need to go from the left side to the right side can all pass through the vicinity of one crossbeam 5. For example: the pipeline assembly at one end of the frame passes through the inner space or above the longitudinal beam 6 on the left side, and after reaching the nearest crossbeam 5, it passes from the top or front or rear side of the same crossbeam 5 to the inner space of the longitudinal beam 6 on the right side, or to the recessed position where the crossbeam 5 is laid. The layout structure of the present invention can improve the efficiency of pipeline assembly, and the pipelines are neat and orderly after installation, firmly fixed, and have improved reliability. The layout structure is roughly "H"-shaped when viewed from above. The longitudinal pipeline line channels can be reduced as needed and deformed into "h". Longitudinal pipeline line layout channels can also be added to the layout structure as needed to meet various pipeline line layout scenarios. The pipeline line connection channel between the longitudinal channels is unique and is arranged in the middle of the longitudinal channel.

[0022] Furthermore, the longitudinal beam 6 includes a vertical plate, an upper plate arranged at the upper end of the vertical plate, and a lower plate arranged at the lower end of the vertical plate; the inner spaces of the two longitudinal beams 6 are arranged facing each other; the bolts 7 on the longitudinal beam 6 are reversed, and the heads of the bolts 7 are located in the inner space of the longitudinal beam 6. Specifically, the bolt heads of the bolts 7 on the vertical plate are located at the bottom, and the ends of the bolts 7 extend upward out of the upper plate; the bolt heads of the bolts 7 on the upper plate are located on the inside, and the ends of the bolts 7 extend out of the box longitudinal beam 6; the nuts of the bolts 7 on the lower plate are located at the top, and the lower ends extend to the bottom of the lower plate and are provided with gaskets and nuts. The present invention adopts a structure in which the nuts are reversed, and the direction of the mounting bolts 7 is adjusted, so that the inner space of the longitudinal beam 6 can be utilized to a greater extent, and interference wear between the pipeline and the ends of the bolts 7 and the nuts can be avoided.

[0023] Specifically, a long strip bracket 8 is fixedly positioned in the recessed portion of the crossbeam 5. The length of the long strip bracket 8 is aligned or nearly aligned with the length of the longitudinal beam 6. Fixing members for securing the pipeline assembly are positioned between the long strip bracket 8 and the pipeline assembly. The pipeline assembly can be positioned along the long strip bracket 8, serving as support for the assembly. The fixing members can be commonly used components for securing the pipeline, such as pipe clamps 9, cable clips, or cable ties 10. The long strip bracket 8 can be provided with mounting holes for mounting studs, bolts 7, and expansion ties 10, as required, with controlled spacing between them. The pipe clamps 9 and cable ties 10 are connected by bolts 7, and the assembly is secured by the pipe clamps 9 and cable ties 10. The long strip bracket 8 of the present invention can simultaneously meet the securing requirements of different pipelines, with controllable spacing, improving assembly consistency and aesthetically pleasing pipeline installation. The long strip bracket 8 can be secured to one or more crossbeams 5 by welding or bolting 7.

[0024] Specifically, fixtures for securing the pipeline assembly are provided on the longitudinal beam 6 at positions corresponding to each assembly. Each assembly is secured to the longitudinal beam 6 via its own fixture. The fixtures can be commonly used to secure pipelines, such as pipe clamps 9 or cable ties 10. The pipe clamps 9 or cable ties 10 are secured to the longitudinal beam 6 via bolts 7. The structure for securing the pipeline assembly is conventional and will not be described in detail.

[0025] Specifically, the pipeline assembly may include a first assembly 1, a second assembly 2, a third assembly 3, and a fourth assembly 4. The portion of the first assembly 1 located in front of the frontmost crossbeam 5 is disposed on the upper end surface of the longitudinal beam 6, and the portions of the second assembly 2, the third assembly 3, and the fourth assembly 4 located in front of the frontmost crossbeam 5 are layered from top to bottom in the inner space of the longitudinal beam 6. The transverse portions of the first assembly 1, the second assembly 2, the third assembly 3, and the fourth assembly 4 pass through the frontmost crossbeam 5. The portions of the first assembly 1, the second assembly 2, the third assembly 3, and the fourth assembly 4 located behind the frontmost crossbeam 5 are laid flat on the crossbeam 5. The portions of the first assembly 1, the second assembly 2, the third assembly 3, and the fourth assembly 4 located behind the frontmost crossbeam 5 may also pass through the rearmost crossbeam 5 and then be layered in the inner space of the other side longitudinal beam 6. These arrangements are not fixed, and the number of assemblies is not fixed. They can be arranged as needed, as long as the arrangement principles and conditions of the present invention are met. The first assembly 1, the second assembly 2, the third assembly 3, and the fourth assembly 4 on the longitudinal beam 6 can be fixed to the vertical plate and the upper and lower plates of the longitudinal beam 6 by means of pipe clamps 9 or cable ties 10. They are fixed in layers in the vertical direction so as not to interfere with each other and are securely fixed. At the same time, the bolts 7 are installed with the heads of the bolts 7 facing the outside of the longitudinal beam 6 to avoid interference with the pipelines. The recessed portion between two or more crossbeams 5 is lower than the longitudinal beam 6 and can be used as a pipeline channel for horizontal paving of the pipelines. The pipelines connecting the left side parts of the vehicle are arranged on the left, and the pipelines connecting the right side parts of the vehicle are arranged on the right. The pipelines that need to go from the left to the right can all pass through near the front crossbeam 5. The pipelines of each assembly are fixed separately on the left and right in the horizontal direction so as to be firm and secure without interfering with each other. A long strip bracket 8 can be welded to the upper surface of the middle part of the two cross beams 5. A bracket can be welded on the long strip bracket 8 or a double-sided cable tie 10 with a base can be used to fix the pipeline line. The fixing spacing can be adjusted as needed. The double-sided cable tie 10 with a base can be installed on the bracket in advance and pipelines can be laid on both sides at the same time.

[0026] A passenger car using the above-mentioned automobile pipeline layout structure includes a frame, a longitudinal beam 6 and at least one cross beam 5 on the frame, and a pipeline assembly passes through the longitudinal beam 6 and the cross beam 5.

[0027] During specific implementation: the parts of each assembly of the pipeline that pass through the longitudinal beam 6 are arranged in layers and fixed in upper and lower layers, and the parts that pass through the crossbeams 5 are laid out horizontally and fixed. The crossbeam 5 of the utility model is sunken and combined with the long strip bracket 8 to form a horizontally arranged pipeline channel. It can increase the pipeline channel, so that the pipeline can be installed flat, and can solve the problem of low installation efficiency of the pipeline passing through the longitudinal beam 6 holes and the problem of interference between the pipeline and the bolt 7. The assembly of the utility model is separated horizontally to the left and right, and layered vertically up and down. The pipeline of each assembly has its own channel, which can realize the separate fixation of the pipelines of different assemblies. It can avoid the repeated bundling of pipelines of different assemblies, save materials, and improve the overall aesthetics of the pipeline. Only one crossbeam 5 is required to arrange the pipeline assembly from left to right. It avoids the repeated bundling of pipelines of different assemblies crossing on the crossbeam 5 and improving the overall aesthetics of the pipeline.

[0028] The technical features of the above-described embodiments may be combined in any manner, and as long as there are no contradictions in the combination of these technical features, they shall be deemed to be within the scope of this specification. Without departing from the overall concept of the present invention, the technical solutions of the present invention, their equivalent replacements or modifications, and certain changes and improvements made thereto shall also be deemed to be within the scope of protection of the present invention.
