TECHNICAL FIELD
[0001] The utility model relates to vehicle pipeline route arrangement technical field especially, vehicle pipeline route connecting structure and vehicle. BACKGROUND
[0002] A large number of pipelines and wire harnesses are arranged on the vehicle to transmit liquid or gaseous substances or signals in the vehicle. The suspension platform of the vehicle refers to a suspension structure with air bags and hydraulic cylinders, which can jump up and down relative to the chassis (fixed platform) during the driving of the vehicle. The pipeline route connected between the suspension platform and the chassis includes brake pipes, hydraulic pipes, liquid cooling pipes, centralized lubrication pipes and wire harnesses, which are usually in a non-disconnected form, i.e. the pipeline route is a whole pipe, one end of which is connected to the chassis and the other end is connected to the suspension platform. The suspension platform jumps up and down through the stroke change of the air bags and the cylinders, and the pipeline route is adapted to the stroke influence of the suspension platform by reserving a suitable length. However, this inevitably causes friction and collision between the pipeline route and the devices or structures around it when the pipeline route jumps or vibrates, which leads to dynamic fatigue failure of the pipeline route over a long period of time. After the pipeline route is damaged, it is difficult to repair the disconnected two sections of the pipeline route, and it is necessary to additionally increase a partition joint and find a suitable joint welding point to fix the partition joint or replace the whole pipeline route, so the repair of the pipeline route is very difficult.

[0020] The pipeline line connected between two platforms of prior art vehicle is usually a whole pipeline, and the both ends of the pipeline line are connected on two platforms respectively, and the whole pipeline line is reserved with appropriate length, and the pipeline line is not easy to repair after being fatigued and broken due to jumping, and it is necessary to additionally increase the partition wall joint and find suitable joint welding points to fix the partition wall joint or replace the whole pipeline line, so that the pipeline line repair is very difficult.
[0021] In order to solve the problem that the pipeline line of existing vehicle is difficult to repair after being broken, the utility model provides a kind of pipeline line connecting structure of vehicle and vehicle using the connecting structure, and its basic invention concept is: the pipeline line connected between two platforms is designed as multi-section split type connecting structure, wherein the first and last two sections of pipeline are respectively fixed on two platforms, the both ends of intermediate section pipeline are respectively connected on the pipeline fixing device of two platforms and are communicated with the pipeline fixed on two platforms through pipeline fixing device, and intermediate section pipeline is reserved with certain excess, so when the pipeline line of vehicle is fatigued and broken after long-time jumping, just replace intermediate section pipeline to replace and repair, thereby the pipeline line repair difficulty can be greatly reduced.
[0022] Based on the above invention concept, the utility model embodiment is introduced in detail as follows.
[0023] The embodiment of the utility model vehicle pipeline line connecting structure:
[0024] As Figure 1 shown, the vehicle pipeline connection structure includes a first platform 1, a second platform 4, and a pipeline connected between the two platforms, the pipeline is a multi-segment split connection structure, including a split first platform pipeline 2, a second platform pipeline 5 and an intermediate pipeline 3, the first platform pipeline 2 is fixed on the first platform 1, the second platform pipeline 5 is fixed on the second platform 4, and the intermediate pipeline 3 is connected between the first and second platform pipelines, and the length of the intermediate pipeline 3 is reserved. A pipeline fixing device 6 is provided on the first platform 1 and the second platform 4 respectively, and the two ends of the intermediate pipeline 3 are connected to the pipeline fixing devices 6 of the first and second platforms respectively and are in communication with the first and second platform pipelines through the pipeline fixing devices 6 (the communication here can be pipeline lumen communication or pipeline electrical communication), which ensures the functionality of the pipeline.
[0025] The pipeline fixing device 6 is a pipeline partition wall joint or a wire harness plug-in. When the pipeline needs to transmit liquid or gaseous substances, the pipeline fixing device 6 can use a pipeline partition wall joint, and the pipeline and the pipeline partition wall joint can be connected quickly using a quick plug-in method, which is convenient to connect. When the pipeline has multiple pipelines, a plurality of pipeline fixing devices 6 can be provided on the two platforms, so that all the pipeline fixing devices 6 on the same platform are arranged in sequence and spaced apart in the left-right or front-back direction, and the pipeline is connected one-to-one with the pipeline fixing device 6. The purpose of arranging all the pipeline fixing devices 6 on the same platform in sequence and spaced apart in the left-right or front-back direction is to avoid the cross-twisting of multiple pipelines as much as possible and to accelerate the wear of the pipeline and shorten its service life. When the pipeline needs to transmit signals, the pipeline fixing device 6 can use a wire harness plug-in. When the signal line of the pipeline has multiple signal lines, the wire harness plug-in has two or more plug-in holes, and all the plug-in holes are arranged in sequence and spaced apart in the left-right or front-back direction and are connected one-to-one with the signal line. The purpose of arranging all the plug-in holes in sequence and spaced apart in the left-right or front-back direction is to avoid the cross-twisting of multiple signal lines as much as possible and to cause signal interference and accelerate the wear of the signal line.
[0026] Preferably, the wiring direction of the pipeline fixing device 6 of the first platform 1 and the second platform 4 is perpendicular to each other, which has the advantage of bending the intermediate pipeline 3 as much as possible, and the bending degree is lighter, thereby reducing the wear degree of the intermediate pipeline 3 and prolonging the service life of the intermediate pipeline 3. Of course, in actual application, the wiring direction of the pipeline fixing device 6 of the two platforms can be flexibly adjusted according to the relative position of the first platform 1 and the second platform 4.
[0027] In one of the embodiments of the present embodiment, the first platform 1 is a fixed platform such as a chassis, and the second platform 4 is a floating platform that can float relative to the first platform 1. During the driving of the vehicle, the second platform 4 will jump up and down relative to the first platform 1, and at this time, the intermediate pipeline 3 will also jump. The intermediate pipeline 3 is provided with a certain length allowance to adapt to the stroke of the second platform 4. Of course, in other embodiments, the first platform 1 and the second platform 4 can also be floating platforms, and at this time, the intermediate pipeline 3 is provided with a suitable length to adapt to the platform jumping; the first platform 1 and the second platform 4 can also be fixed platforms, and at this time, the intermediate pipeline 3 is still provided with a suitable length to adapt to the length change of the pipeline caused by thermal expansion and cold contraction. That is, no matter which case, as long as the intermediate pipeline 3 is provided with a length allowance, the intermediate pipeline 3 can jump or vibrate and rub against or collide with the devices or structures around it during the driving of the vehicle. The vehicle pipeline connection structure of the present application can be applied, and the intermediate pipeline 3 can be replaced when it is damaged.
[0028] The vehicle pipeline connection structure of the present application uses a multi-section split connection structure for the pipeline connected between the two platforms, and increases pipeline fixing devices on the two platforms for pipeline butt joint. The intermediate pipeline is provided with a suitable allowance, so that after the pipeline is fatigued and damaged after a long time of jumping, the intermediate pipeline can be replaced and repaired, without the need to additionally increase the partition joint, and without the need to replace the pipeline as a whole, thereby greatly reducing the pipeline repair difficulty. The intermediate pipeline can be designed according to a standard part, and is convenient for regular maintenance.
[0029] The present application also provides a vehicle embodiment. The vehicle adopts a new pipeline connection structure, which has the same structure as the above-mentioned specific embodiments of the vehicle pipeline connection structure, and will not be described here.
[0030] The above is only a preferred embodiment of the present application, and does not limit the present application. The patent protection scope of the present application is subject to the claims, and any equivalent structural changes made according to the content of the specification and drawings of the present application should also be included in the protection scope of the present application.
