Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of automobile air filter element, in particular to an air filter element mounting structure. BACKGROUND

[0002] During the working process of the engine, a large amount of air needs to be sucked in. If the air is not filtered, the dust suspended in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. Larger particles entering between the piston and the cylinder will cause serious cylinder pulling phenomenon, which is particularly serious in dry and sandy working environment.

[0003] The air filter element mounting structure of the present disclosure is mainly used on the sand vehicle, mounted in front of the carburetor or air inlet pipe, and plays a role in filtering dust and sand in the air to ensure that sufficient and clean air enters the cylinder.

[0004] The existing air filter element mounting structure, as shown in Figure 1 , comprises a shell 1 and a cover plate 11 sealing the shell 1. An air outlet 101 is arranged on the side wall of the shell 1, and an air inlet cover 111 is mounted on the cover plate 11 and communicates with the inner cavity of the shell 1. An open-ended filter element 2 is arranged in the inner cavity of the shell, wherein the filter element inner cavity 21 of the filter element 2 is connected with the air outlet 101, and the outer wall of the filter element 2, the cover plate 11 and the inner wall of the inner cavity of the shell 1 form a first chamber 100, which communicates with the air inlet flow passage of the air inlet cover 111.

[0005] During the working process of the above-mentioned filter element 2, the air from the outside enters the first chamber 100 through the air inlet cover 111, and the gas in the first chamber 100 moves from the outside of the filter element 2 to the filter element inner cavity 21, thereby filtering the air. The gas in the filter element inner cavity 21 is sucked into the engine.

[0006] Since this kind of filter element 2 structure is mainly used on the sand vehicle, therefore, the engine needs to suck in more clean air. The engine sucks in only clean air in the filter element inner cavity 21 each time. In the case of unchanged filter element 2 model, the amount of clean air sucked into the engine is limited, which is not conducive to improving the performance of the engine. In this case, the above-mentioned problem can only be solved by replacing a larger model filter element 2. However, the sand vehicle is small in size and compact in structure. When replacing a larger model filter element, the air filter element will occupy a larger area, which is not convenient for manufacturing a small and compact sand vehicle.

[0007] Therefore, it is necessary to design an air filter element mounting structure which is compact in structure and can provide a large amount of clean air, which is a technical problem to be solved by those skilled in the art. CONTENT OF THE INVENTION

[0041] In order to make the purpose, features and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.

[0042] As shown in Figure 2 , including the shell 1, wherein the shell 1 is provided with the air inlet 105 and the air outlet 101 which are communicated with the inner cavity of the shell 1, and the filter core 2 is arranged in the inner cavity of the shell 1, as shown in Figure 4 , the filter core 2 includes a filter core cavity 21 with one side opening, as shown in Figure 5 , the filter core cavity 21 is connected with the air inlet 105, the outer wall of the filter core 2 and the inner wall of the inner cavity of the shell 1 form a first chamber 100, the first chamber 100 is communicated with the air outlet 101, and the volume of the first chamber 100 is greater than that of the filter core cavity 21.

[0043] Through the above arrangement, on the basis of the same filter core 2 model, the original filter core cavity 21 is connected with the air outlet 101, which is changed to be connected with the air inlet 105, and then the volume of the filter core cavity 21 is limited to be smaller than that of the first chamber 100, so that it can be concluded that after the improvement, the engine mainly inhales clean air in the first chamber 100 during work, compared with inhaling clean air in the filter core cavity 21, the intake amount of clean air is improved, and after the clean air in the first chamber 100 is sucked away, the air outside will be continuously supplied to the first chamber 100 through the filter core cavity 21, so that the filtering efficiency of the filter core 2 for air is improved under the same condition, thereby improving the performance of the engine.

[0044] Specifically, in order to realize the installation of the filter core 2, in the embodiment, as shown in Figure 3 , an opening is arranged on one side wall of the shell 1, and the opening on the shell 1 is used to put the filter core 2 into the inner cavity of the shell 1, so as to facilitate the installation of the filter core 2.

[0045] At the same time, the cover plate 11 is arranged to block the opening of the shell 1, and the buckle assembly 3 is further arranged to fix the cover plate 11 and the shell 1.

[0046] Specifically, as shown in Figure 3 and Figure 5 The air inlet 105 is arranged on the cover plate 11, and when the cover plate 11 covers the opening of the shell 1, the air inlet 105 is in communication with the filter element inner cavity 21 on the filter element 2.

[0047] In order to fix the cover plate 11 on the shell 1, in the embodiment, as shown in Figure 3 and Figure 4 The buckle assembly 3 includes a rotating shaft 31, a buckle and protrusion 33, and a buckle and elastic sheet 32, specifically, the rotating shaft 31 is fixedly installed on the outer wall of the shell 1, the buckle and protrusion 33 is fixedly installed on the cover plate 11, and one end of the buckle and elastic sheet 32 is rotatably connected with the rotating shaft 31, and the other end of the buckle and elastic sheet 32 is buckled with the buckle and protrusion 33.

[0048] In another embodiment, the buckle assembly 3 includes a rotating shaft 31, a buckle and protrusion 33, and a buckle and elastic sheet 32, wherein the rotating shaft 31 is fixedly installed on the cover plate 11, the buckle and protrusion 33 is fixedly installed on the shell 1, one end of the buckle and elastic sheet 32 is rotatably installed on the rotating shaft 31, and the other end of the buckle and elastic sheet 32 is buckled with the buckle and protrusion 33. Since this scheme is similar to the scheme in the previous embodiment, the installation of the rotating shaft 31 and the buckle and protrusion 33 will not be shown in the drawings.

[0049] Since the air inlet 105 is arranged on the cover plate 11, in order to guide the air from the outside to the air inlet 105, in the embodiment, as shown in Figure 3 , an air inlet cover 111 is installed on the cover plate 11, wherein the air inlet cover 111 is fixedly connected with the cover plate 11 by screws, and an air inlet flow channel is arranged in the air inlet cover 111, and the air inlet flow channel is in communication with the air inlet 105.

[0050] In the prior art, as shown in Figure 1 , the air outlet 101 is installed on the side wall of the shell 1, and a mounting groove 102 is arranged around the side wall of the air outlet 101, wherein a limiting plate 103 is fixedly installed in the inner cavity of the shell 1, and during the installation process, the filter element 2 changes from the dashed line position to the solid line position in Figure 1 , and the process is as follows: first, align the opening end of the filter element inner cavity 21 with the mounting groove 102, and insert the end wall of the filter element 2 into the mounting groove 102, where the side away from the mounting groove 102 is defined as the tail of the filter element 2, at this time, the tail of the filter element 2 is in abutment with the limiting plate 103 during the downward pressing process, thereby placing the filter element 2 in a horizontal state, and here, the front end of the filter element 2 is provided with a rubber seat 22, and the front end of the filter element 2 is elastic, so as to clamp the filter element 2 between the mounting groove 102 and the limiting plate 103.

[0051] Here, since the filter element 2 is in a horizontal state, in order to prevent the filter element 2 from continuing to move downward, a limiting groove 1031 is arranged on the limiting plate 103, wherein the limiting groove 1031 is in an L shape, and the tail of the filter element 2 is supported by the limiting groove 1031, thereby preventing the filter element 2 from moving downward.

[0052] In the prior art, the inner cavity of the shell 1 is also blocked by the cover plate 11, and at this time, there is a gap between the cover plate 11 and the peripheral wall of the filter element 2. Since the air filter here is mainly used on a sand buggy, the vibration amplitude of the sand buggy is large during use, and at this time, the tail of the filter element 2 is easy to shake out of the limiting groove 1031 due to vibration, thereby causing the filter element 2 to be not firmly installed, and thereby affecting the performance of the engine.

[0053] Therefore, in the present embodiment, as shown in Figure 4 and Figure 5 the side of the inner cavity of the shell 1 away from the opening of the shell 1 is provided with a positioning seat 104, wherein the tail of the filter element 2 is installed in the positioning seat 104, and the outer wall of the tail of the filter element 2 abuts against the inner wall of the positioning seat 104, thereby achieving preliminary installation of the filter element 2. It is worth noting that the cover plate 11 is also provided with a clamping groove 112 coaxially arranged with the air inlet 105, the front end of the filter element 2 is inserted into the clamping groove 112, and the top wall of the filter element 2 abuts against the cover plate 11, thereby enabling the airflow in the air inlet cover 111 to smoothly enter the inner cavity 21 of the filter element, and then the gas enters the first chamber 100 through the inner cavity 21 of the filter element, preventing the air in the air inlet cover 111 from directly entering the first chamber 100, thereby preventing the air in the inner cavity of the first chamber 100 from being contaminated or having large-particle dust impurities.

[0054] After the front end of the filter element 2 is inserted into the clamping groove 112, the cover plate 11 and the shell 1 are fixed by using the buckle assembly 3, thereby achieving fixation of the filter element 2, preventing the filter element 2 from shaking due to vibration of the sand buggy, and improving the stability of the filter element 2.

[0055] In order to further improve the stability of the installation of the filter element 2, a rubber seat 22 is arranged at the front end of the filter element 2, and when the filter element 2 is installed in the inner cavity of the shell 1, the rubber seat 22 abuts against the cover plate 11. After the cover plate 11 and the shell 1 are fixed by the buckle assembly 3, the rubber seat 22 is elastically deformed, thereby improving the stability of the filter element 2, and at the same time, the sealing performance of the connection between the inner cavity 21 of the filter element and the air inlet 105 is enhanced, thereby preventing the gas in the first chamber 100 from being contaminated.

[0056] It should be understood that the various forms of flow shown above can be used to reorder, add or delete steps. For example, the steps described in the present disclosure can be executed in parallel, in sequence or in different orders, as long as the desired results of the technical solutions disclosed in the present disclosure can be achieved, and the present disclosure is not limited herein.
