[0029] The following description is intended to fully illustrate the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0030] See also Figure 1-6 The utility model provides a technical solution: an air filter installation structure, comprising:

[0031] The vehicle frame 200 supports and connects the engine 300. A pipeline 301 and an air filter body 400 are sequentially arranged above the engine 300. A lifting hole 302 is reserved on the side of the engine 300. The air filter mounting structure 100 is configured to support the air filter body 400. The air filter mounting structure 100 includes:

[0032] A first mounting plate 101, comprising a vertical plate portion 1011 and a horizontal plate portion 1012 connected in sequence along a length direction, wherein the vertical plate portion 1011 is connected to the hanging hole 302 via a connector, and the horizontal plate portion 1012 is located between the pipeline 301 and the air filter body 400, and supports and connects the air filter body 400;

[0033] a first reinforcement member 102, connected between the transverse plate portion 1012 and the vertical plate portion 1011, and located on the side of the first mounting plate 101 facing the pipeline 301. A notch 1021 is defined on the side of the first reinforcement member 102 facing the pipeline 301 to allow passage of the pipeline 301. The cross-sectional dimensions of the first reinforcement member 102 gradually increase as it approaches the connection between the transverse plate portion 1012 and the vertical plate portion 1011;

[0034] The second mounting plate 103 is supported and connected between the vehicle frame 200 and the first mounting plate 101 .

[0035] The first mounting plate 101 is supported and connected between the engine 300 and the air filter body 400. The first mounting plate 101 is mounted on the engine 300 using the hoisting holes 302 reserved on the engine 300. The horizontal plate portion 1012 provides support for the air filter body 400, and the vertical plate portion 1011 is close to the engine 300, thereby ensuring the support strength of the air filter body 400 while occupying a small installation space.

[0036] By adding a first reinforcement member 102 between the transverse plate portion 1012 and the vertical plate portion 1011 and providing a notch 1021 in the first reinforcement member 102 for circumventing the pipeline, the cross-sectional dimensions of the first reinforcement member 102 are further limited. The first reinforcement member 102 improves the connection strength between the transverse plate portion 1012 and the vertical plate portion 1011 while not affecting the layout of the pipelines on the engine 300.

[0037] By adding the second mounting plate 103 between the first mounting plate 101 and the vehicle frame 200 , the vibration between the engine 300 and the first mounting plate 101 is eliminated by the second mounting plate 103 , thereby reducing the resonance between the air filter mounting structure 100 and the engine 300 .

[0038] In one embodiment, the first mounting plate 101 and the air filter body 400 , and the first mounting plate 101 and the second mounting plate 103 are connected via connecting members. Optionally, the connecting members are bolts.

[0039] Preferably, the angle between the horizontal plate portion 1012 and the vertical plate portion 1011 is 90°.

[0040] For further information, see Figure 3 and 4 The vertical plate portion 1011 is provided with a rectangular mounting hole 10111. The axial direction of the mounting hole 10111 is parallel to the length of the horizontal plate portion 1012. The mounting hole 10111 is arranged along the length of the vertical plate portion 1011, and the connecting member is configured to slide along the length of the mounting hole 10111. Preferably, the connecting member is a bolt, and the radial cross-section of the vertical plate portion 1011 is waist-shaped to match the shape of the bolt. During installation, the first mounting plate 101 can slide on the connecting member through the mounting hole 10111, thereby adjusting the distance between the air filter body 400 and the engine 300.

[0041] In order to enhance the effect of the first reinforcement 102 on the strength of the first mounting plate 101, the first reinforcement 102 and the first mounting plate 101 are welded. Furthermore, the length of the first reinforcement 102 on the vertical plate portion 1011 is not less than one third of the total length of the vertical plate portion 1011, and the length of the first reinforcement 102 on the horizontal plate portion 1012 is not less than one third of the total length of the horizontal plate portion 1012.

[0042] For further information, see Figure 3The notch 1021 is a V-shaped notch 1021. In the vertical direction, the upper end of the notch 1021 is not lower than the upper end of the pipeline 301, and the lower end of the notch 1021 is not higher than the lower end of the pipeline 301. Preferably, in the vertical direction, the upper end of the notch 1021 is flush with the upper end of the pipeline 301, and the lower end of the notch 1021 is flush with the lower end of the pipeline 301.

[0043] For further information, see Figure 1 、 3 and 4, the air filter installation structure 100 further includes:

[0044] The third reinforcement member 105 is disposed outside the vertical plate portion 1011 and extends outward away from the air filter body 400. Furthermore, in the vertical direction, the upper end of the third reinforcement member 105 is higher than the lower end of the first reinforcement member 102, that is, the third reinforcement member 105 is partially disposed on the side of the vertical plate opposite the first reinforcement member 102. Preferably, the third reinforcement member 105 is welded to the vertical plate portion 1011.

[0045] For further information, see Figure 2 On a horizontal plane, the length direction of the second mounting plate 103 is perpendicular to the length direction of the transverse plate portion 1012. This allows the first mounting plate 101 and the second mounting plate 103 to provide support for the air filter body 400 in different directions.

[0046] Furthermore, a connection position of the second mounting plate 103 on the first mounting plate 101 corresponds to a connection position of the first reinforcement member 102 on the first mounting plate 101 .

[0047] Furthermore, the second mounting plate 103 is connected to the first mounting plate 101 and the vehicle frame 200 at both ends along its length. A first bend 1031 and a second bend 1032 are sequentially spaced along its length, with the first bend 1031 and the second bend 1032 being arranged in opposite directions. By providing the second mounting plate 103 with continuous and oppositely directed bends, the second mounting plate 103 can locally deform to eliminate vibrations when subjected to forces acting between the vehicle frame 200 and the first mounting plate 101, thereby further preventing resonance between the engine 300 and the overall structure.

[0048] Specifically, the second mounting plate 103 includes a first transverse plate 1033, a second vertical plate 1034 and a third transverse plate 1035. The vehicle frame 200, the first transverse plate 1033, the second vertical plate 1034, the third transverse plate 1035 and the transverse plate portion 1012 are connected in sequence. A first bending portion 1031 is formed between the first transverse plate 1033 and the second vertical plate 1034, and a second bending portion 1032 is formed between the second vertical plate 1034 and the third transverse plate 1035. The third transverse plate 1035 is parallel to the first transverse plate 1033, and the second vertical plate 1034 is perpendicular to the first transverse plate 1033 and the third transverse plate 1035, respectively.

[0049] For further information, see Figure 5 and 6 , the air filter installation structure 100 further includes:

[0050] The second reinforcement member 104 is disposed on the inner side of the first bend 1031 and the inner side of the second bend 1032, respectively. The cross-sectional dimensions of the second reinforcement member 104 on the inner side of the first bend 1031 gradually increase as it approaches the center of the first bend 1031, and the cross-sectional dimensions of the second reinforcement member 104 on the inner side of the second bend 1032 gradually increase as it approaches the center of the second bend 1032. Preferably, the second reinforcement member 104 and the second mounting plate 103 are welded. Preferably, the cross-sectional shape of the second reinforcement member 104 is an isosceles triangle, with the waist of the triangle corresponding to the two sides of the bend.

[0051] In summary, the air filter mounting structure 100 supports and connects the first mounting plate 101 between the engine 300 and the air filter body 400, wherein the first mounting plate 101 is mounted on the engine 300 using the hoisting holes 302 reserved on the engine 300, the horizontal plate portion 1012 provides support for the air filter body 400, and the vertical plate portion 1011 is close to the engine 300, ensuring the support strength of the air filter body 400 while occupying a small installation space. By adding a first reinforcement member 102 between the horizontal plate portion 1012 and the vertical plate portion 1011, and providing a notch 1021 on the first reinforcement member 102 for avoiding the pipeline, the cross-sectional size of the first reinforcement member 102 is further limited. The first reinforcement member 102 improves the connection strength between the horizontal plate portion 1012 and the vertical plate portion 1011 while not affecting the layout of the pipeline on the engine 300.

[0052] By adding the second mounting plate 103 between the first mounting plate 101 and the vehicle frame 200 , the vibration between the engine 300 and the first mounting plate 101 is eliminated by the second mounting plate 103 , thereby reducing the resonance between the air filter mounting structure 100 and the engine 300 .

[0053] The above structure reduces the types of materials, reduces the processing steps, improves work efficiency, simplifies the processing technology, and has relatively low requirements for technology, equipment, and personnel skills, thereby reducing production and processing costs and alleviating the labor intensity of workers.

[0054] By improving the air filter mounting structure 100, the problem of compact space when adding filter post-processing to the National IV and Euro V engine 300 of the skid loader can be greatly improved, and the air filter assembly has no installation space problem. The loosening and resonance of the air filter assembly caused by the high-speed operation of the engine 300 can be reduced. At the same time, the requirements for processing technology and equipment are reduced, the process flow is accelerated, and production efficiency is improved. The air filter mounting structure 100 is simple to process and can greatly speed up the production process.

[0055] The embodiments described above are only used to illustrate the technical ideas and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The scope of patent application of the present invention cannot be limited by these embodiments alone. That is, any equivalent changes or modifications made according to the spirit disclosed by the present invention still fall within the patent scope of the present invention.
