[0004] After the existing air conditioning filter is inserted into the vehicle and installed, the insertion port needs to be closed with a cover and fixed with screws. However, the internal structure of the vehicle is compact, and the method of fixing with a cover and screws makes it difficult to disassemble the air conditioning filter when replacing it. Therefore, the market urgently needs to develop an easy-to-replace vehicle filter to help people solve the existing problem. Utility Model Content

[0005] The purpose of the present utility model is to provide a vehicle filter that is easy to replace, so as to solve the problem proposed in the above background technology that after the existing air conditioning filter is inserted into the vehicle and installed, the insertion port needs to be closed by a cover plate and fixed with screws, but the internal structure of the vehicle is compact, and the air conditioning filter is difficult to disassemble when replacing it by fixing it with a cover plate and screws.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a vehicle filter that is easy to replace, comprising a filter mounting frame, a slot being provided inside the filter mounting frame, a plurality of telescopic tubes being fixedly provided at the rear end of the slot, a telescopic rod being provided inside the telescopic tube, a filter being provided inside the slot, a filter element being provided in the middle of the filter, the front ends of the end faces on both sides of the filter mounting frame being fixedly connected to a locking assembly, a guide rod being fixedly connected to an end face on one side of the locking assembly, a rectangular slider being provided on one side of the locking assembly, one end of the rectangular slider extending through the side end face of the filter mounting frame to the interior of the slot and being fixedly connected to a triangular locking tongue.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) This utility model adopts a unique linkage mechanism design of a triangular lock tongue and a telescopic rod. During the installation process, the rear end of the filter first squeezes the triangular lock tongue to make it retract inward. When the filter continues to penetrate into the designed position, the telescopic rod is pushed and compressed by the top plate. After the filter is fully in place, the triangular lock tongue and the telescopic rod are reset with the help of the restoring force of the second spring and the first spring respectively, thus achieving a fast and stable installation of the filter. When disassembling, the filter can be unlocked by simply retracting the triangular lock tongue through a simple paddle operation. At the same time, the first spring pushes the telescopic rod forward to assist the filter in sliding out of the slot. The entire process does not require the use of screws or complex tools, which greatly simplifies the filter replacement process and improves the user's operational convenience.

[0015] (2) In this utility model, the design of the telescopic rod and the first spring not only provides the necessary support force for the filter during installation, ensuring a tight fit between the filter and the slot, but also effectively prevents the filter from shifting due to vibration or airflow impact, thereby ensuring the normal operation of the vehicle air conditioning system and the air filtration effect. At the same time, during the disassembly process, the restoring force of the first spring becomes the power source for pushing the filter forward, reducing the frictional resistance between the filter and the slot, making the filter easier to remove and further reducing the difficulty of replacing the filter.

[0016] (3) The design of the locking assembly in this utility model also reflects the innovation of this utility model. The filter can be locked and unlocked by a simple paddle operation, which is not only easy and quick to operate, but also avoids the risk of loosening caused by traditional screw fixing methods. At the same time, the synergistic effect of the guide rod, rectangular slider, and second spring components ensures the stability and reliability of the triangular lock tongue during the locking and unlocking process, thereby improving the safety and efficiency of the entire filter replacement process.

When the filter 3 is installed, the filter 3 is inserted into the slot 101 through the socket 102.

[0024] See also Figure 3 and Figure 4 A plurality of telescopic tubes 2 are fixedly provided at the rear end of the slot 101, a telescopic rod 201 is provided inside the telescopic tube 2, the rear end of the telescopic rod 201 is fixedly connected to a limit plate 202 inside the telescopic tube 2, a first spring 203 is provided inside the telescopic tube 2 at the rear end of the limit plate 202, the front end of the telescopic rod 201 extends out of the front end of the telescopic tube 2 and is fixedly connected to a top plate 204. When the filter 3 is inserted into the slot 101, the rear end of the filter 3 fits into the front end of the top plate 204 and pushes the top plate 204 to move backward, causing the telescopic rod 201 to extend into the telescopic tube 2 and compress the first spring 203.

[0025] See also Figure 2 and Figure 4 The front ends of both sides of the filter mounting frame 1 are fixedly connected with a locking assembly 4, and one end face of the interior of the locking assembly 4 is fixedly connected with a guide rod 402. A rectangular slider 5 is provided on one side of the interior of the locking assembly 4. One end of the rectangular slider 5 passes through the side end face of the filter mounting frame 1 and extends to the inside of the slot 101 and is fixedly connected with a triangular lock tongue 502. A circular groove 501 is provided on one end face of the rectangular slider 5. One end of the guide rod 402 is inserted into the inner step of the circular groove 501. A second spring 403 is provided on the outside of the guide rod 402 and on one side of the rectangular slider 5. A strip opening is provided on the front end face of the locking assembly 4 401, the front end face of the rectangular slider 5 is fixedly connected to a paddle 503, and the front end of the paddle 503 extends through the strip opening 401 and out of the front end face of the locking assembly 4. When the filter 3 is inserted into the slot 101 along the socket 102, the rear end of the filter 3 squeezes the triangular lock tongue 502, so that the triangular lock tongue 502 is retracted into the locking assembly 4 and compresses the second spring 403. When the filter 3 is fully inserted into the slot 101, the front end of the filter 3 moves to the rear end of the triangular lock tongue 502, and the restoring force of the second spring 403 pushes the triangular lock tongue 502 out to lock the front end of the filter 3.

[0026] See also Figure 1-4 When disassembly is required, the rectangular slider 5 is moved by pulling the paddle 503, so that the triangular lock tongue 502 is retracted into the locking assembly 4 again, and the telescopic rod 201 is pushed forward by the first spring 203, and then the top plate 204 pushes the filter 3 to move forward inside the slot 101, so that the front end of the filter 3 extends out of the socket 102 for easy removal.

[0027] Working principle: When in use, first align the filter 3 with the slot 101 through the socket 102 and insert it. During the insertion process, the rear end of the filter 3 will first contact and squeeze the triangular lock tongue 502, causing the triangular lock tongue 502 and the rectangular slider 5 connected to it to move toward the inside of the locking assembly 4 under the guidance of the guide rod 402, while compressing the second spring 403. As the filter 3 continues to go deeper, when it is about to be fully inserted into the slot 101, the rear end of the filter 3 will contact the top plate 204 at the front end of the telescopic tube 2, and push the top plate 204 and the telescopic rod 201 to move backward, thereby compressing the first spring 203. When the filter 3 is fully inserted into the slot 101, the second spring 403 pushes the triangular lock tongue 502 to reset, extending to the front end of the filter 3 to lock it in place, while the first spring 203 remains compressed to push the filter 3 during subsequent disassembly. When the filter 3 needs to be removed, the user only needs to pull the paddle 503 outward, which, through the rectangular slider 5, drives the triangular locking tongue 502 back into the locking assembly 4, releasing the filter 3. At this time, the restoring force of the first spring 203 pushes the telescopic rod 201 and the top plate 204 forward, thereby pushing the filter 3 to slide forward inside the slot 101 until the front end of the filter 3 is completely extended from the socket 102, allowing the user to easily remove and replace the filter 3.
