Abstract
Description
Technical Field
[0001] This utility model relates to a fuel tank, specifically a fuel tank with an integrated air filter intake. Background Technology
[0002] In the existing technology, the air intake of the air filter is generally designed as a single part installed on the whole vehicle. It requires a separate space and fixing structure to perform the installation. On the one hand, it occupies additional vehicle installation space, and on the other hand, the independent fixing structure makes production and installation more complicated. Utility Model Content
[0003] This utility model proposes a fuel tank with an integrated air filter intake duct. Its purpose is to overcome the above-mentioned shortcomings of the prior art, reduce the space occupied by the air filter intake duct, eliminate the need for an independent fixed structure, and simplify production and installation.
[0004] The technical solution of this utility model is as follows: A fuel tank integrating an air filter intake duct, the structure of which includes a fuel tank body, with an air filter intake duct integrally formed at the center of the fuel tank body, extending from front to back. The air filter intake duct is tubular and runs through the center of the fuel tank body, with the rear end of the air filter intake duct extending outward and protruding from the rear side of the fuel tank body. While ensuring sufficient volume in the fuel tank body, the middle part is hollowed out during design, and the air filter intake duct is integrally formed, achieving an integrated design.
[0005] Preferably, the air filter intake duct at the end located on the front side of the fuel tank body is covered with a filter screen. This allows for pre-filtration.
[0006] Preferably, the end of the air filter intake duct protruding from the rear side of the fuel tank body is connected to the air filter via a bellows. No additional fixing structure is required, improving the convenience of production and installation.
[0007] The advantages of this utility model are: reasonable structural design, which integrates the air filter intake into the fuel tank space, effectively reducing space occupation, freeing up space in the whole vehicle, saving fixed structure, eliminating the need for separate installation of the intake, effectively simplifying production and assembly procedures, and reducing production costs.

[0011] In the diagram, 1 is the fuel tank body, 2 is the air filter intake, and 3 is the filter screen. Detailed Implementation
[0012] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.
[0013] like Figure 1 , 2 As shown, a fuel tank integrating an air filter intake duct has the following structure: a fuel tank body 1, an air filter intake duct 2 integrally formed in the center of the fuel tank body 1, the air filter intake duct 2 being tubular and penetrating the center of the fuel tank body 1, the end of the air filter intake duct 2 located on the front side of the fuel tank body 1 being covered with a filter screen 3, and the end of the air filter intake duct 2 located on the rear side of the fuel tank body 1 extending outward and protruding from the rear side of the fuel tank body 1.
[0014] Based on the above structure, while ensuring the fuel tank body 1 meets volume requirements, the middle section is hollowed out during the design phase, and the air filter intake duct 2 is integrally molded, achieving an integrated design. The filter screen 3 is installed for pre-filtration.
[0015] like Figure 3 As shown, during installation, the end of the air filter intake duct 2 protruding from the rear side of the fuel tank body 1 is connected to the air filter via a bellows. No additional fixing structure is required, improving the convenience of production and installation.
[0016] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.
[0017] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
