Technical Field

[0001] The utility model relates to the technical field of filters, in particular to an automobile air filter. Background Art

[0002] With the rapid development of the automobile industry, the maintenance and replacement efficiency of automobile parts has become a focus of attention. As an important part of the automobile engine system, the automobile air filter is responsible for filtering impurities in the air entering the engine combustion chamber to protect the engine from wear and maintain good combustion efficiency. Traditional automobile air filters mostly use full bolts or nuts to fix the upper and lower covers. Although this ensures the stability of the structure, frequent disassembly and assembly operations are cumbersome and time-consuming during daily maintenance and replacement of filter elements, especially the tightening and loosening of nuts, which often require special tools to assist, causing inconvenience to users. Utility Model Content

[0003] In view of the deficiencies in the background technology, the utility model provides an automobile air filter.

[0004] The technical solution adopted by the utility model is: an automobile air filter, comprising:

[0005] An upper cover plate, wherein a plurality of connection holes are provided at equal intervals on the upper cover plate;

[0006] A plurality of connecting rods, wherein the upper end of each connecting rod is provided with a connecting screw, and the connecting screw passes through the connecting hole and is locked and fixed by a nut, and the lower end of each connecting rod is provided with a connecting section, and a locking hole is provided on the connecting section;

[0007] The lower cover plate is provided with a plurality of connection grooves for inserting the connection sections at equal intervals, and a locking mechanism cooperating with the lock hole is provided in the connection groove.

[0008] Furthermore, the locking mechanism includes a telescopic locking rod, a pressure spring and a wrench. A locking rod groove is provided above the connecting groove. One end of the telescopic locking rod slides with the telescopic hole on one side of the locking rod groove. The pressure spring is mounted on the telescopic locking rod. One end of the pressure spring abuts against the side wall of the locking rod groove, and the other end abuts against the wrench on the telescopic locking rod.

[0009] Furthermore, the wrench is a "T"-shaped structure.

[0010] Furthermore, a limiting groove for inserting a wrench is provided on one side of the locking rod groove. When the telescopic locking rod of the locking mechanism is inserted into the lock hole to complete the locking, the wrench can be inserted into the above-mentioned limiting groove by rotating the telescopic locking rod.

[0011] The beneficial effects of the utility model are:

[0012] 1. Significantly improve disassembly and assembly efficiency: This application combines the use of a nut connection with a locking mechanism in the automobile air filter, and when disassembly is required, the locking mechanism is used to achieve a quick disassembly and assembly function. Compared with the traditional all-nut connection method, maintenance personnel do not need to spend a lot of time tightening or loosening multiple nuts, which significantly shortens the filter replacement time and improves work efficiency.

[0013] 2. Reduce maintenance costs: Simplifying the disassembly and assembly process reduces the reliance on professional tools and the complexity of maintenance operations, thereby reducing labor and tool costs. At the same time, the easy-to-operate design also helps reduce damage caused by improper operation and prolongs the service life of the filter and its components.

[0014] 3. Enhance user experience: The quick disassembly and assembly design makes it easier for both professional technicians and ordinary car owners to complete the filter replacement work by themselves, which improves user satisfaction and participation and enhances the market competitiveness of the product.

[0015] In addition to the objects, features and advantages described above, the present invention has other objects, features and advantages.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] The utility model provides an automobile air filter.

[0023] In this embodiment, refer to Figure 1-2 , the automobile air filter comprises:

[0024] An upper cover plate 1, on which a plurality of connection holes 2 are evenly spaced;

[0025] A plurality of connecting rods 3, wherein the upper end of each connecting rod is provided with a connecting screw 4, wherein the connecting screw passes through the connecting hole and is locked and fixed by a nut 5, and the lower end of each connecting rod is provided with a connecting section 6, wherein a locking hole 7 is provided on the connecting section;

[0026] The lower cover plate 8 is provided with a plurality of connection grooves 9 for inserting the connection sections at equal intervals, and a locking mechanism cooperating with the above-mentioned locking hole is provided in the connection groove.

[0027] After adopting the above technical solution, the filter housing can be quickly disassembled and assembled. When disassembly and assembly is required, the connecting rod can be pulled out from the connecting groove of the lower cover after unlocking it with the locking mechanism. When installing, the connecting section of the connecting rod can be inserted into the connecting groove and locked with the locking mechanism. Disassembly and assembly are very convenient. This design not only ensures the stable sealing of the filter housing, but also significantly improves the efficiency of maintenance, reduces the difficulty of maintenance, and improves the user's operating experience.

[0028] Specifically, the locking mechanism includes a telescopic locking rod 10, a pressure spring 11 and a wrench 12. A locking rod groove 13 is provided above the connecting groove. One end of the telescopic locking rod is slidably matched with a telescopic hole 14 on one side of the locking rod groove. The pressure spring is sleeved on the telescopic locking rod. One end of the pressure spring is against the side wall of the locking rod groove, and the other end is against the wrench on the telescopic locking rod.

[0029] The locking mechanism includes a telescopic locking rod, a pressure spring and a wrench, with a simple structure and easy operation. When unlocking, the locking rod can be pulled out of the lock hole by holding the wrench.

[0030] Specifically, the wrench is a "T"-shaped structure; a limiting groove 15 for the wrench to be inserted is provided on one side of the locking rod groove. When the telescopic locking rod of the locking mechanism is inserted into the lock hole to complete the locking, the wrench can be inserted into the above-mentioned limiting groove by rotating the telescopic locking rod.

[0031] The additional limit groove design on one side of the locking rod groove provides a clear positioning point for the wrench, ensuring that the wrench can be accurately inserted into the limit groove after locking is completed. This not only further simplifies the operating process, improves the accuracy of the operation, and avoids the damage that may be caused by misoperation, but also ensures the stability of the entire locking structure, so that the entire filter housing can still maintain a good connection state under extreme vibration or impact conditions, thereby improving the reliability of the overall structure.
