[0037] It should be noted that if a directional indication is involved in the embodiment of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text is to include three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution that satisfies both A and B.

[0039] See also Figure 1 and Figure 2 The present invention provides a flexible vehicle pipeline installation verification platform 100, which includes a frame 10, a fixed assembly and an adjustment assembly. The structure of the frame 10 corresponds to the frame shape of the vehicle. The frame 10 is used to test-assemble the vehicle pipeline. Generally speaking, the vehicle pipeline is assembled by being arranged along the frame and fixed to the frame. Specifically, for vehicles of the same series and model, the frame shape is the same, and the structure of the frame 10 is designed with reference to the frame. It can be understood that for vehicles of different models, the shape of the frame 10 is designed differently.

[0040] The fixed assembly and the adjusting assembly refer to the assemblies in the vehicle assembly parts that are prone to cause pipeline assembly problems. For example, the vehicle pipeline needs to connect the assembly, the assembly that is easy to block the extension direction of the vehicle pipeline, and / or the assembly that is easy to interfere with the vehicle pipeline. Specifically, the fixed assembly refers to the assembly that does not need to be adjusted in the vehicle pipeline assembly design to optimize the pipeline assembly scheme. And the adjusting assembly refers to the assembly that needs to be adjusted in the vehicle pipeline assembly design to optimize the pipeline assembly scheme. Specifically, in one embodiment, the fixed assembly includes a cab front suspension assembly 21, a cab rear suspension assembly 22, a dryer assembly 23 and a urea tank assembly 24. It can be understood that the fixed assembly is not limited to the above-mentioned assemblies, but can also be other assemblies that need to be paid attention to during the pipeline assembly process. In another embodiment, the adjustment assembly includes a gas reservoir assembly 31 and a battery frame assembly 32. The gas reservoir and the battery frame can adjust their layout positions according to the needs of vehicle pipeline assembly. Similarly, the adjustment assembly is not limited to these two assemblies, and can also be other assemblies that need to be paid attention to during the pipeline assembly process and can adjust their positions according to the pipeline assembly requirements. It can be understood that the above two embodiments can be implemented separately or in combination.

[0041] The fixed assembly is detachably arranged on the frame 10, so as to facilitate replacement and adjustment according to the change of the vehicle model, and the adjustment assembly is adjustably arranged on the frame 10, so as to adjust its position according to the pipeline assembly needs. In vehicle production, the flexible vehicle pipeline installation verification platform 100 can be used to verify the feasibility and repeatability of the vehicle pipeline assembly plan, without waiting for the actual vehicle production and trial assembly verification of the relevant vehicle model, so that the vehicle pipeline assembly design plan can be fully verified at a lower economic and time cost, improve the design quality of the vehicle pipeline assembly plan, reduce the actual assembly problems on the production line, and improve the vehicle design quality and production efficiency. In addition, the above-mentioned flexible vehicle pipeline installation verification platform 100 can also be applied to the trial production and trial assembly of pipeline problem rectification plans, no longer relying entirely on the on-line actual vehicle assembly verification, and the plan is solidified after verification on the verification platform, which greatly improves efficiency. In addition, for pipeline assembly problems, multiple rounds of trial assembly verification can be organized on the flexible vehicle pipeline installation verification platform 100. After determining the best state, the pipeline is sealed, and the sealing state is used as the basis for determining the responsibility for the problem in the future.

[0042] It is understood that the number of the above-mentioned fixed assembly parts and the adjustment assembly parts is not limited and can be set according to the requirements of the actual vehicle model. In one embodiment, the gas reservoir assembly 31 is provided with two, and the battery frame assembly 32 is provided with one.

In this way, in the present embodiment, during the assembly verification process, the gas cylinder assembly 31 can be conveniently moved to a plurality of positions as required. In the present embodiment, preferably, the mounting fittings are provided with 8. In this way, the gas cylinder assembly 31 has at least 8 mounting positions to meet the needs of adjusting the positions of most gas cylinders.

[0044] See also Figure 5 and Figure 6 Similarly, in order to achieve the position adjustment installation of the battery frame assembly 32, the battery frame assembly 32 is provided with a mounting member, and the frame 10 is provided with a plurality of mounting fittings with different positions, and the mounting member can be selectively matched with one of the plurality of mounting fittings, so that the battery frame assembly 32 can be installed on the frame 10 in an adjustable position. In this way, in the present embodiment, during the assembly verification process, the battery frame assembly 32 can be conveniently moved to a plurality of positions as needed. In this embodiment, it is preferred that the mounting fittings are provided with 5. In this way, the battery frame assembly 32 has at least 5 installation positions to meet the needs of adjusting the position of most battery frames.

[0045] The specific structures of the mounting member and the mounting fitting are not limited, and they may be, for example, mounting grooves and mounting blocks that cooperate with each other. In a preferred embodiment, one of the mounting member and the mounting fitting is a bolt, and the other is a screw hole.

[0046] The present invention also provides a vehicle pipeline assembly method. Using the flexible vehicle pipeline installation verification platform 100 as described above, the vehicle pipeline assembly method includes the following steps:

[0047] Referring to the vehicle model scheme, the frame 10 is established;

[0054] If the problem recurs, investigate the cause of the problem and optimize the pipeline assembly plan;

[0055] If the problem does not recur, re-evaluate the repeatability of the pipeline assembly solution.

[0056] In the above-mentioned vehicle pipeline assembly method, the verification of the vehicle pipeline assembly design scheme, the verification of assembly repeatability accuracy and the verification of assembly problem reproduction are involved. These verifications do not need to wait for the actual production of the relevant vehicle models, but can be verified at any time using the flexible vehicle pipeline installation verification platform 100 provided by the present invention, thereby improving production efficiency, and can be fully verified at low cost, thereby improving the design quality of the vehicle pipeline assembly scheme and reducing the probability of pipeline assembly problems in the actual production process. And after each verification is completed, the pipeline assembly status can be sealed as a basis for determining the responsibility for the problem.
