Detailed Description
It is easily understood that, according to the technical solution of the present invention, a plurality of alternative structural modes and implementation modes can be proposed by those skilled in the art without changing the spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical solutions of the present invention, and should not be considered as limiting or restricting the technical solutions of the present invention in their entirety or in any other way.
The terms of orientation of up, down, left, right, front, back, top, bottom, and the like referred to or may be referred to in this specification are defined relative to the configuration shown in the drawings, and are relative terms, and thus may be changed correspondingly according to the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms. Furthermore, the terms "first," "second," "third," and the like are used for descriptive and descriptive purposes only and not for purposes of indication or implication as to the relative importance of the respective components.
Referring to FIG. 1, a schematic diagram of one embodiment of a fuel line assembly 100 according to the present disclosure is shown.
The fuel line assembly 100 includes a fuel line 1 for connecting to a canister flush pump of an automobile engine compartment, and a damper 2 configured at the fuel line 1 for reducing noise of the fuel line 1.
It should be understood that the canister purge pump (also known as a canister purge pump, a canister purge pump, etc.) is used to draw gasoline vapor from the vehicle fuel tank through a conduit into the upper portion of the canister and fresh air from the lower portion of the canister into the canister during vehicle operation or shut down. After the engine is shut down, the gasoline vapor is mixed with fresh air in the canister and stored in the canister. After the engine is started, the gasoline vapor in the carbon tank participates in the combustion process again. The carbon canister flush pump is a noise source that generates noise.
The reason why the canister flush pump is used is that since gasoline is a volatile fuel, fuel in the fuel tank gradually volatilizes to increase the pressure inside the fuel tank, and therefore, the pressure needs to be balanced. In the past, the fuel tank cap was made into a pressure limiting valve that opened when the pressure exceeded a threshold, venting the gasoline vapor to the atmosphere, but this was detrimental to fuel economy and environmental protection. The canister flush pump is therefore provided. The inside of the fuel tank is provided with active carbon with strong adsorbability, and through the process, the purposes of fuel saving and environmental protection are achieved.
The damper 2 is used to reduce the noise of the fuel line 1, for example, the damper 2 can be of a weight to reduce the degree of vibration of the fuel line 1 during operation and/or be constructed of a material.
Through foretell fuel pipeline structure, can effectively reduce the noise of carbon canister flush pump, improve the noise level to reduce customer complains about, improve the comfort that the user took.
As shown in the figure, the damper 2 is configured to wrap the outer layer of the fuel pipeline 1, and the noise generated by the fuel pipeline 1 can be reduced or even eliminated in all directions through the wrapping mode. Of course, depending on the actual location of the fuel line 1 in the engine compartment and the distribution of the surrounding components, the damper 2 can also be arranged in a correspondingly non-fully wrapped manner in the fuel line 1.
With regard to the aforementioned "certain materials", it is exemplary that the damper 2 is composed of a viscoelastic material. Viscoelastic materials are materials used exclusively as damping layers, and commonly used viscoelastic materials include asphalt, water-soluble substances, latex, and epoxy resins, and fillers and solvents may also be added as appropriate to increase the damping thereof. Examples of the filler are metal powder having a large specific gravity, sieved yellow sand, sawdust, calcium carbonate, graphite, and the like. The material can even be made in the form of liquids, glues, pads and tapes (e.g. pitch based materials, water soluble materials, latex, epoxy resins). Specifically, the damper 2 is made of a viscoelastic material such as polymer or rubber with excellent damping and noise reduction performance, and can better play a role in damping.
It can also be seen that the dampers 2 are configured as damping plates and that the damping plates are arranged next to one another in the fuel line 1. The structural form of the damping fin can be flexibly adapted to fuel pipelines with various shapes and structures, and the structural forms which are arranged side by side can better cooperatively play the functions of the damping fins. Of course, the damping disks can be arranged next to one another, as a result of which the noise reduction can be carried out more intensively at the location of the fuel line 1 where they are located.
In the embodiment of the fuel line 1, it can be seen that the fuel line 1 is composed of a curved pipe 11 and a straight pipe 12 which are connected to each other in this order. The matching of the bent pipe and the straight pipe can enable the whole fuel pipeline 1 to well adapt to the arrangement position where the whole fuel pipeline is actually located and the arrangement mode of peripheral parts, and the fuel pipeline 1 can also easily reach an expected target position, so that the universality of the fuel pipeline 1 is expanded.
In this regard, the damper 2 can be arranged both at the bent pipe 11 and at the straight pipe 12. The figure shows, by way of example, that the damper 2 is arranged at a straight pipe 12 of the fuel line 1, simply because a straight pipe tends to have a larger receiving area and is flat. The damper 2 can also be arranged at a bend, if the bend also has a certain receiving area, or if the angle of the bend is not too large.
It should be understood that the number, arrangement position, shape, positional relationship between each other, and material of the dampers 2 are exemplary, and those skilled in the art will know after reading the technical solution of the present invention that various features thereof can be modified according to actual situations and needs. The size of the damper 2 depends, for example, on the degree to which the noise needs to be improved. For another example, a plurality of the dampers 2 are respectively arranged at a plurality of straight pipes 12 of the fuel pipeline 1, so that the noise existing over the whole length of the fuel pipeline 1 can be more comprehensively reduced. However, it is not necessary that all the straight tubes 12 be constructed with the damper 2, depending on the actual situation (e.g., the density of peripheral parts of the respective straight tubes, the place to be subjected to noise reduction, since there may be some places where noise is present and is not transmitted to the user).
It should be understood that the fuel pipeline assembly 100 of the present invention may be installed in an automobile engine assembly, which further comprises an automobile engine, wherein the carbon canister flushing pump of the automobile engine is connected to the fuel pipeline 1. In addition, the automobile engine assembly may be mounted on various automobiles, including gasoline automobiles, diesel automobiles, cars, trucks, passenger cars, hybrid electric automobiles, and the like. Therefore, the subject matter of the present invention is also directed to protecting the automobile engine assembly equipped with the fuel line assembly 100 of the present invention, and various vehicles equipped with the automobile engine assembly.
To sum up, through the technical scheme of the utility model the transmission of energy can be reduced under the condition that does not change the pipeline trend or increase length, effective noise reduction improves the comfort that the customer took to reduce the customer and complain. The technical scheme has short change period, low cost and obvious noise improvement effect. Meanwhile, the technical scheme can be flexibly applied to pipeline design of different platforms, and the design requirements of the platform are met.
It should be understood that all of the above preferred embodiments are exemplary and not restrictive, and that various modifications and changes in the specific embodiments described above, which may occur to those skilled in the art upon reading the teachings of the present invention, are intended to be within the scope of the appended claims.
