Description

Technical Field

[0001] This utility model relates to the field of automotive filter technology, specifically to an anti-vibration and anti-detachment structure for automotive filters. Background Technology

[0002] Automotive filters are essential components for the normal operation of a car. Their main function is to filter impurities that enter the engine or lubrication system, ensuring the engine operates efficiently and cleanly, and extending its service life. During vehicle operation, filters are typically fixed in a designated location within the vehicle body or engine compartment using a specific mounting structure.

[0003] In areas with uneven ground, vehicles frequently experience bumps, impacts, and vibrations. However, traditional filter installation structures often only consider the need for fixation on smooth roads or under normal operating conditions. They may simply be plugged into the equipment, and their connection method and fastening strength may not be sufficient to cope with extreme vibration and impact environments. Therefore, when using a car in areas with uneven ground and strong vibrations, the filter may loosen or fall off, affecting the vehicle's safety. Utility Model Content

[0004] (I) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned filter element connection being unreliable and possibly loosening or falling off due to vibration, and to provide a shock-resistant and anti-detachment structure for automotive filter elements.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a shock-resistant and anti-detachment structure for an automotive filter element, comprising a barrel body and a main filter element. One end of the barrel body is connected to a flange, and the other end of the barrel body is connected to a cover. A buckle is provided on the outer wall of the barrel body near the cover, and the buckle is fastened to the barrel body. One end face of the main filter element is pressed tightly against the inner end face of the flange by the cover. An annular limiting ring is provided inside the cover, and a protrusion that cooperates with the limiting ring is provided on the end face of the main filter element near the cover.

[0008] As an improvement: the end face of the main filter element near the flange is a recessed surface, and a groove is provided in the recessed surface of the main filter element. The inner end face of the flange is provided with a boss of an annular structure, and the boss is snapped into the groove.

[0009] As an improvement: a sleeve is provided around the outer wall of the barrel near the end of the shell cover, a sealing ring is provided inside the sleeve, and an insert plate adapted to the inner diameter of the sleeve is connected to one end face of the shell cover, and the insert plate is inserted into the sleeve.

[0010] As an improvement: a safety filter element is inserted inside the main filter element, one end face of which abuts against the recessed surface of the main filter element, and the other end face abuts against the inner end face of the flange.

[0011] As an improvement, the flange is fixedly connected to the barrel body by multiple bolts.

[0012] (III) Beneficial Effects

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. A cover is attached to one end of the barrel by a snap-fit, which presses the main filter element through the cover and makes one end of the main filter element fit tightly against the inner end face of the flange. This ensures the accurate fixation of the main filter element in the axial position, increases the mechanical constraint between the main filter element and the barrel, and thus effectively resists the displacement of the main filter element caused by vibration, preventing the main filter element from loosening or falling off.

[0015] 2. The limiting ring inside the shell fits with the protrusion on the end face of the main filter element, providing radial positioning and support for the main filter element, preventing it from shaking inside the barrel, and further enhancing the stability of the main filter element in a vibration environment.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0024] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0025] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] Combined with appendix Figure 1 As shown, an anti-vibration and anti-detachment structure for an automotive filter element includes a barrel body 1 and a main filter element 2. One end of the barrel body 1 is connected to a flange 3, and the flange 3 is fixedly connected to the barrel body 1 by multiple bolts. This design facilitates the connection and disassembly of the flange 3 and the barrel body 1.

[0027] To enhance the shock resistance and anti-detachment performance of the main filter element 2, combined with the attached... Figure 1 and Figure 3 As shown, the other end of the barrel 1 is connected to the shell cover 4. The outer wall of the barrel 1 near the shell cover 4 is provided with a buckle 5, which is fastened to the barrel 1. One end face of the main filter element 2 is pressed tightly against the inner end face of the flange 3 by the shell cover 4. The end face of the main filter element 2 and the end face of the flange 3 form an axial seal through the tight contact of the rear shell cover 4. At the same time, the contact structure undertakes the radial limiting function to ensure that the main filter element 2 maintains a stable assembly position during operation and avoids sealing failure due to vibration and other factors.

[0028] Combined with appendix Figure 1 and Figure 4 As shown, the shell cover 4 is provided with an annular limiting ring 6, and the main filter element 2 is provided with a protrusion 7 on the end face near the shell cover 4 that cooperates with the limiting ring 6. After assembly, the protrusion 7 on the outer periphery of the main filter element 2 can form a precise fit with the annular limiting ring 6 to form a radial constraint, which restricts the radial displacement and shaking of the main filter element 2 in the barrel 1. At the same time, the locking pressure after the shell is installed will press the two ends of the main filter element 2 tightly to avoid the main filter element 2 from shaking axially along the barrel 1 and the failure of the seal.

[0029] Through the coordinated action of the buckle 5, the cover 4, and the limiting ring 6, the main filter element 2 is more stable and reliable under vibration conditions, effectively improving its shock resistance and preventing loosening and failure caused by vibration.

[0030] At the same time, combined with the appendix Figure 1 and Figure 2As shown, the end face of the main filter element 2 near the flange 3 is a recessed surface. A groove 8 is provided on the recessed surface of the main filter element 2. A boss with an annular structure is provided on the inner end face of the flange 3. The boss is snapped into the groove 8. Through the interference fit between the groove 8 and the boss, a radial sealing barrier is formed by the elastic compression after the main filter element 2 and the barrel 1 are assembled, so as to prevent unfiltered airflow from entering the barrel 1 from the gap.

[0031] To prevent filtration failure due to damage to main filter element 2, in conjunction with the attached... Figure 1 and Figure 5 As shown, a safety filter element 12 is inserted into the main filter element 2. One end face of the safety filter element 12 abuts against the recessed surface of the main filter element 2, and the other end face abuts against the inner end face of the flange 3. Under the tight compression of the main filter element 2, the connection between the end face of the safety filter element 12 and the end face of the flange 3 forms a seal, which not only fixes the safety filter element 12, but also effectively prevents air leakage.

[0032] In the above setup, when the main filter element 2 fails due to damage or other reasons, the safety filter element 12 can temporarily intercept large particulate impurities to prevent them from directly entering the engine and causing damage to the engine. When the main filter element 2 is working normally, the safety filter element 12 is in a non-working state.

[0033] Combined with appendix Figure 3 As shown, a sleeve 9 is provided around the outer wall of the barrel body 1 near the end of the cover 4. A sealing ring 11 is provided inside the sleeve 9. An insert plate 10 adapted to the inner diameter of the sleeve 9 is connected to one end face of the cover 4. The insert plate 10 is inserted into the sleeve 9. When the cover 4 is connected to the barrel body 1, the insert plate 10 is inserted into the sleeve 9, and the sealing ring 11 is compressed to form a reliable seal, effectively preventing gas from leaking from the connection between the cover 4 and the barrel body 1.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
