[0002] The air filter in a car's air conditioning system is a crucial component for filtering air. Its main function is to intercept dust, odors, and other impurities in the air, ensuring cleaner and healthier air enters the vehicle. The filter directly affects the air quality inside the car, and its full functionality depends not only on its stable support within the filter box but also on the regular replacement of high-efficiency filters.

[0003] Existing automotive air conditioning filters need to be fixed in a housing. However, the housing structure for installing filters varies depending on the car model and brand. For example, a certain brand's filter housing has a housing and a filter box cover. The filter is placed inside the housing. To improve the installation stability of the filter, the housing has an integrated structure for snapping the filter in place. The filter box cover also has a plug for fixing the filter. During installation, the above structures need to be matched to achieve the desired installation.

[0004] However, air conditioning filters are consumables that need to be replaced regularly. Most car owners do not go back to the brand's 4S store to replace the air conditioning filter, but choose car repair shops or car detailing shops. These shops generally have difficulty purchasing original factory-matched filters, and original factory-matched filters are often more expensive, resulting in higher replacement costs. Due to the compatibility of their structures, replacement and disassembly are relatively difficult. Utility Model Content

[0005] The purpose of this utility model is to provide an air conditioning filter for automobiles, which aims to solve the technical problems of high price, high replacement cost, and relatively difficult replacement and disassembly caused by the compatibility of the structure of the original factory matched filter in the prior art.

[0010] Furthermore, there are two first reinforcing ribs, located on the outer sides of the two protrusions respectively, and the first reinforcing ribs are vertically arranged on the surface of the fixed plate.

[0011] Furthermore, symmetrical snap-fit ​​blocks are arranged on both sides of the surface of the protrusion, the two protrusions are located between the two snap-fit ​​blocks, and the upper end of the snap-fit ​​blocks is inclined outward.

[0012] Furthermore, the upper surface of the protrusion is lower than the upper surface of the snap-fit ​​block.

[0013] Furthermore, the protruding length of the protrusion is greater than the protruding length of most of the snap-fit ​​blocks.

[0014] Furthermore, the protrusion has a cuboid structure and a length of 1.5-2.5cm.

[0015] Furthermore, the filter body includes a first side and a second side arranged parallel to each other, and a third side and a fourth side arranged parallel to each other.

[0032] like Figure 1 , Figure 2 As shown, this embodiment discloses an air conditioning filter for automobiles, including a plate-shaped filter body 1. The filter body 1 includes several parallel pleated structures. Specifically, the filter body 1 includes a first side 1.1 and a second side 1.2 arranged parallel to each other, and a third side 1.3 and a fourth side 1.4 arranged parallel to each other. The third side 1.3 and the fourth side 1.4 are arranged parallel to the pleated structures. The length of the second side 1.2 is less than that of the first side 1.1, and the length of the third side 1.3 is less than that of the fourth side 1.4. The connector 2 is disposed at the end of the third side 1.3 near the first side 1.1, and the end of the third side 1.3 away from the connector 2 is connected to the end of the second side 1.2 to form an inclined fifth side 1.5.

[0033] The filter element body 1 has a connector 2 on one outer side. Specifically, the connector 2 is located on the upper end of the third side 1.3 near the first side. The connector 2 includes two parallel protrusions 3, with a clearance space between the two protrusions 3. The protrusions 3 are perpendicular to the side of the frame, and the bottom plane of the two protrusions 3 has a concave structure.

[0034] The connector 2 also includes a fixing plate 4, and the two protrusions 3 are vertically disposed on one surface of the fixing plate 4. By fixing the connector 2 to the side of the filter element body 1 with the fixing plate 4, the connection stability between the connector 2 and the filter element body 1 can be improved, and it is also convenient for mold production, overall installation, and lower production costs.

[0035] A first reinforcing rib 6 is provided at the connection between the protrusion 3 and the fixing plate 4. The first reinforcing rib 6 is a triangular plate structure, including two right-angled sides, which are connected to the fixing plate 4. The first reinforcing rib 6, with its triangular plate structure, strengthens the connection between the protrusion 3 and the fixing plate 4, increasing the strength of the protrusion 3 and reducing the likelihood of breakage during use.

[0036] Preferably, there are two first reinforcing ribs 6, located on the outer sides of the two protrusions 3 respectively, and the first reinforcing ribs 6 are vertically arranged on the surface of the fixing plate 4. The first reinforcing ribs 6 are located on the outer sides of the protrusions 3 to ensure that the gap between the two protrusions 3 is large enough to facilitate the subsequent insertion of the pin of the filter box cover 7. At the same time, the first reinforcing ribs 6 are located on the outer side to enhance the fixing effect after the pin is inserted, reduce the amplitude of left and right shaking, and improve the installation stability.

[0037] More preferably, the fixing plate 4 has symmetrically arranged locking blocks 5 on both sides of the surface where the protrusions 3 are provided, with the two protrusions 3 located between the two locking blocks 5. Specifically, the locking block 5 is composed of two triangular connecting parts and a rectangular part. The triangular connecting parts include two right-angled sides, which are respectively connected to the fixing plate 4 and the rectangular part. The rectangular part is located above the hypotenuse, connecting the two triangular connecting parts, and is perpendicular to the fixing plate 4, thus enhancing the fixing effect on the filter element body 1 after installation. Furthermore, the rectangular part surface of the locking block 5 is inclined outward and downward, which facilitates the smooth insertion of the locking block 5 into the locking block of the filter housing during installation.

[0038] In a preferred embodiment, the protruding length of the protrusion 3 is greater than the protruding length of most of the snap-fit ​​blocks 5, which facilitates the insertion of the pin of the filter box cover 7 and prevents the pin from detaching from the filter element body 1 due to vibration during use, thereby improving structural strength while reducing material costs.

[0039] Preferably, the upper surface of the protrusion 3 is lower than the upper surface of the snap-fit ​​block, which improves the stability of the connection structure between the filter box cover 7 and the filter element body 1 after the cover is closed.

[0040] Specifically, the protrusion 3 has a cuboid structure and a length of 1.5-2.5 cm. This length ensures the stability of the connection after the pin is inserted and also ensures that the filtration area of ​​the filter element body 1 is fully utilized.

[0041] Figure 3 and Figure 4 As shown, the air conditioning filter of this embodiment can be replaced by installing it in the filter housing of a certain model. A snap-fit ​​structure is provided on one side of the inner opening of the filter housing. Specifically, the snap-fit ​​structure includes two inwardly extending snap blocks. A fixing space is formed below the snap blocks for inserting the ends of the two snap-fit ​​blocks 5 of the connector. The top of the snap-fit ​​block 5 abuts against the bottom of the snap block to form a snap-fit ​​structure. A space is provided between the two snap blocks for inserting two protrusions 3. The filter housing also includes a filter box cover 7 that can be closed with the housing. The filter box cover 7 is provided with a locking member, which includes a pinching part 8. A vertical pin 10 is provided at the lower end of the pinching part 8, and a horizontal latch pin 9 is provided on the locking member.

[0042] When installing the filter element body 1, the second side 1.2 of this embodiment is inserted into the filter housing with the entire body facing downward. The side with the connector 2 is inserted into the side with the snap-fit ​​structure inside the housing. Since the filter element body 1 has inward telescopicity, the snap-fit ​​block 5 is engaged with the snap-fit ​​block. The top of the snap-fit ​​block 5 extends into the bottom of the snap-fit ​​block, thereby achieving the abutment and fixation between the top of the snap-fit ​​block 5 and the bottom of the snap-fit ​​block.

[0043] When closing, rotate the horizontal latch pin 9 of the filter box cover 7 to be parallel to the protrusion 3, and then insert the end with the locking member into the space corresponding to the two locking blocks. The vertical pin 10 and the horizontal latch pin 9 pass through the clearance space of the two protrusions 3 and penetrate into the filter housing. By rotating the pinching part 8, the horizontal latch pin 9 can be rotated 90°, and the horizontal latch pin 9 and the protrusion 3 change from a parallel state to a perpendicular state. The horizontal latch pin 9 is just locked between the two protrusions 3, and the filter box cover 7 is locked and fixed to the filter housing.

[0044] When the filter element needs to be replaced, simply rotate the pinching part 8 to rotate the horizontal latch pin 9 90°, so that the horizontal latch pin 9 is parallel to the two protrusions 3. Slightly compress the filter element body 1 inward to deform it, causing the locking block 5 to disengage. The vertical pin 10 and the horizontal latch pin 9 can then pass through the clearance space, separating the filter cover from the filter housing. Then, slightly compress the filter element body 1 inward to disengage the connector 2 from the locking position, allowing the filter element body 1 to be removed for replacement. This method is convenient to assemble and disassemble, has a stable structure, low production cost, and high installation compatibility.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
