Description

Technical Field

[0001] The utility model relates to the technical field of gas filtering equipment, in particular to an air filtering device for new energy vehicles. Background Art

[0002] New energy vehicles (NEVs) are a new type of vehicle that uses unconventional automotive fuels as its power source. While there are many different types of NEVs, hybrid vehicles (HEVs) hold the greatest potential for industrialization and market adoption given current technological advancements and application conditions. Hybrid vehicles, as they are commonly referred to, generally refer to hybrid electric vehicles (HEVs), which utilize a traditional internal combustion engine (diesel or gasoline) and an electric motor as their power sources. Internal combustion engines draw in air from the outside. Poor air quality can cause increased wear on engine components and shorten the engine's service life. Therefore, air filtration systems are required to filter the air drawn in by the engine. Existing air filtration systems often use rectangular filter elements, which concentrate incoming air in a specific area of ​​the filter element, resulting in low overall filter utilization. Utility Model Content

[0003] The purpose of this utility model is to provide an air filtering device for new energy vehicles. The filtering device adopts a cylindrical filter element and evenly arranges multiple air inlets outside the filter element to fully utilize the area of ​​the filter element. A unified air outlet is arranged in the center of the filter element without affecting the air intake of the internal combustion engine.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an air filtering device for a new energy vehicle, comprising a protective shell, a filter element and an air intake manifold, a placement groove matching the filter element is provided inside the protective shell, an air outlet pipe is provided at one end of the protective shell, a plurality of air intake holes are provided on the side of the protective shell, a plurality of air intake pipes are provided on the outside of the protective shell, a plurality of air intake branches matching the air intake holes are evenly provided on each air intake pipe, the air intake branch pipes are installed in the air intake holes and connected with the placement groove, and the ends of the air intake pipes converge on the air intake manifold; the filter element comprises a mounting cylinder, the interior of the mounting cylinder is set to a hollow structure, a plurality of filter layers are provided on the outside of the mounting cylinder, both ends of the mounting cylinder are fixedly connected to a limiting plate, a through hole is provided near the center of the limiting plate of the air outlet pipe, and the interior of the mounting cylinder is connected with the air outlet pipe through the through hole.

[0005] Optionally, metal meshes are provided on the innermost side and the outermost side of the filter layer and at the connection points of each filter layer.

[0006] Optionally, the limiting plate close to the air outlet pipe is threadedly connected to the mounting cylinder.

[0007] Optionally, the air inlet is configured as a gradually expanding structure from outside to inside.

[0008] Optionally, the air intake duct is fixedly connected to the surface of the protective shell.

[0009] The air filter device for new energy vehicles of the present utility model has the following advantages:

[0010] (1) The intake branch pipes are evenly arranged on the outside of the filter element. When air is inhaled, the entire filter element can filter the air, which improves the filtration quality of the air and increases the intake volume. The filtered air enters the internal combustion engine uniformly from the center of the filter element through the exhaust pipe, which will not affect the intake of the internal combustion engine.

[0011] (2) The multi-layer structure of the filter layer can effectively filter out moisture, dust and impurities in the air, and work together to improve the quality of air filtration.

[0012] (3) The metal mesh can play a role of stable support, ensuring that the structure of each filter layer is stable and not deformed. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below with reference to the accompanying drawings. Figure 1 The direction in is the reference.

[0019] like Figure 1-Figure 5As shown, an air filtration device for a new energy vehicle includes a protective shell 1, a filter element 2, and an intake manifold 3. The protective shell 1 has a placement slot 5 that matches the filter element 2. The protective shell 1 is formed by two upper and lower shells that snap together to facilitate the installation of the filter element 2. The intake manifold 3 is located at the right end of the protective shell 1, and an air outlet duct 4 is located at the left end of the protective shell 1. Several air inlet holes 6 are evenly distributed on the side of the protective shell 1. The air inlet holes 6 are arranged in a gradually expanding structure from the outside to the inside to increase the contact area between the air and the filter element 2. Several air inlet ducts 8 are provided on the outside of the protective shell 1. The air inlet ducts 8 are attached to the surface of the protective shell 1 and fixedly connected to the protective shell 1, thereby reducing the space occupied by the filtration device. Each air inlet duct 8 is evenly distributed with several intake branches 7 that match the air inlet holes 6. The intake branches 7 are installed in the air inlet holes 6 and communicate with the placement slot 5. The ends of the air inlet ducts 8 converge on the intake manifold 3.

[0020] Both ends of the mounting tube 9 are fixedly connected to a limit plate 11. The limit plate 11 on the right is a solid structure and is blocked at the right end of the mounting tube 9. The limit plate 11 on the left has a through hole in its center and is threadedly connected to the left end of the mounting tube 9. The interior of the mounting tube 9 is connected to the outlet pipe 4 through the through hole. The innermost and outermost sides of the filter layer 10 and the connection between each filter layer 10 are all provided with a metal mesh 15. The metal mesh 15 can play a role of stable support, ensuring that the structure of each filter layer 10 is stable and does not deform. When the limit plate 11 on the left is removed, each filter layer 10 is an open structure, and each filter layer 10 can be replaced, so that the filter element 2 has the function of being reused.

[0021] External air is sucked in from the intake manifold 3, evenly dispersed on the outer surface of the filter element 2 through the intake branch pipe 7, filtered and purified by each filter layer 10, and the filtered air is collected inside the mounting cylinder 9, and finally sent to the internal combustion engine through the outlet pipe 4. The filtering device can make full use of the entire filter element 2 and can purify the air efficiently. There will be no situation where the air purification level is poor or the intake air cannot ensure sufficient combustion of the internal combustion engine.

[0022] The embodiments described above are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
