Abstract
Description
Technical Field
[0001] This application relates to the field of automotive air conditioning filter installation technology, and more specifically, to an automotive air conditioning filter installation structure. Background Technology
[0002] As people's requirements for the quality of the in-car environment continue to increase, the technology of automotive air conditioning filters is also gradually improving. In the early days, automotive air conditioning systems mainly focused on temperature regulation and paid less attention to air filtration. However, in recent years, due to the aggravation of environmental pollution, there has been an increase in pollutants such as dust, pollen, harmful gases and microorganisms in the air. People in the car are in a relatively enclosed space for a long time and are easily harmed by these pollutants.
[0003] To address the aforementioned issues, existing patents offer solutions. Existing easy-to-replace automotive air conditioning filters use a snap-fit structure to connect the filter to the housing. Existing filter covers are generally fixed with snaps. However, due to limited operating space and the thinness of the snaps and covers, misjudging the installation mode when pressing the covers and snaps can lead to the cover not being securely fixed to the housing. This results in gaps during use and sealing problems. Furthermore, sometimes, due to space constraints inside the vehicle, the user needs to hold the air conditioning filter during removal, which may increase the amount of dust falling from the filter, thus hindering the removal process.
[0004] Therefore, a new automotive air conditioning filter installation structure is needed to solve the above problems. Utility Model Content
[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0006] To address the technical problems mentioned in the background section above, some embodiments of this application provide an automotive air conditioning filter installation structure, including: an installation frame, a sealing cover installed at the front end of the installation frame, an air conditioning filter element inserted into the installation frame, a forward-opening grip groove provided at the middle end of the sealing cover, a grip rod fixed in the grip groove, and opening slots provided at the front end of the sealing cover and at both the left and right ends of the sealing cover, with a connecting mechanism connected in the opening slot, the connecting mechanism being disposed between the installation frame and the sealing cover.
[0007] Furthermore, the connecting mechanism includes a connecting rod, a hinge frame, and a plug rod. The plug rod is inserted between the mounting frame and the sealing cover. The front end of the plug rod passes through the mounting frame. The hinge frame is fixedly connected to the front end face of the plug rod. The connecting rod is rotatably connected to the hinge frame. The hinge frame has a certain degree of elasticity.
[0008] Furthermore, a snap-fit key is fixedly provided on the outer periphery of the plug rod, and two fixed sleeves distributed front and rear are fixedly provided on the inner end of the mounting frame. The fixed sleeves are rotatably engaged with the plug rod. A spring push ring is connected to the front end face of the fixed sleeve at the rear end. The spring push ring includes an anti-slip ring that can abut against the snap-fit key and a compressed spring. The front end face of the snap-fit key can abut against the fixed sleeve at the front end. An opening is provided on the fixed sleeve at the front end, and the snap-fit key and the opening are circumferentially offset.
[0009] Furthermore, a retaining ring is fixed on the rear side wall of the opening groove. The front end of the retaining ring is arc-shaped and can fit against the outer peripheral surface of the connecting rod. The hinge frame has a horizontal retaining groove that runs through the left and right sides and a vertical retaining groove that runs through the front side. The side walls of the horizontal retaining groove and the vertical retaining groove can fit against the outer peripheral surface of the connecting rod.
[0010] Furthermore, each of the two opening slots has an inclined groove at its close end, and there is a gap between the top of the connecting mechanism and the inclined groove.
[0011] Furthermore, an indicator arrow is provided on the front end face of the sealing cover, and a plastic frame is fixed on the rear end face of the sealing cover. The plastic frame has a certain elasticity and is L-shaped, abutting against the lower end of the air conditioning filter. The plastic frame is symmetrically distributed on the left and right. A guide groove is provided in the mounting frame, and the opening of the guide groove faces forward so as to be inserted and matched with the plastic frame.
[0012] The beneficial effects of this application are as follows:
[0013] 1. By setting up connecting rods, hinge frames, and plug-in rods, the plug-in rods are installed between the mounting frame and the sealing cover. A locking key abuts against a fixed sleeve on the mounting frame for positioning. An opening is created in the fixed sleeve, and the circumferential interlacing of the opening and locking key achieves the positioning of the plug-in rod. The horizontal and vertical slots on the hinge frame, along with the retaining ring in the opening slot, restrict the rotation of the connecting rod, enabling the sealing cover to be assembled on the mounting frame. This allows for quick assembly and disassembly, improving work efficiency and ensuring stability. The coaxial arrangement of the connecting rod and plug-in rod increases the exposed area of the connecting mechanism, and the elastic locking method between the connecting rod and the retaining ring guides the disassembly operator, reducing installation omissions.
[0014] 2. Hold the sealing cover with the handle and install the air conditioning filter on the sealing cover using the two plastic brackets distributed on the left and right. This prevents the person disassembling from getting dust on the filter screen during disassembly and installation. The air conditioning filter can be pulled out of the installation frame using the plastic brackets, thus eliminating the need for the person disassembling to pull the air conditioning filter and reducing the amount of dust falling off the air conditioning filter.

[0036] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0037] Reference Figure 1-5 , Figure 7 and 10 An automotive air conditioning filter installation structure includes: a mounting frame 10, a sealing cover 11 mounted on the front end of the mounting frame 10, an air conditioning filter element 12 inserted into the mounting frame 10, a forward-opening grip groove 20 provided in the middle of the sealing cover 11, a grip rod 21 fixedly mounted in the grip groove 20, and opening grooves 23 at the front end of the sealing cover 11 and at both ends of the sealing cover 11, with a connecting mechanism 30 connected within the opening grooves 23. The connecting mechanism 30 is disposed between the mounting frame 10 and the sealing cover 11. During replacement, the user controls the connecting mechanism... After opening at point 30, the sealing cover 11 can be separated from the mounting frame 10. Then, by holding the handle 21, the sealing cover 11 is pulled to remove the air conditioning filter 12 from the mounting frame 10. After removing the old air conditioning filter 12 from the sealing cover 11 and replacing it, the sealing cover 11 is reinserted into the mounting frame 10 to complete the replacement work. The person disassembling does not need to touch the air conditioning filter 12 to pull it out of the mounting frame 10, so that the person disassembling will not get dust on the air conditioning filter 12 during the disassembly process.
[0038] The connecting mechanism 30 includes a connecting rod 31, a hinge frame 32, and a plug rod 33. The plug rod 33 is plugged into the mounting frame 10 and the sealing cover 11. The front end of the plug rod 33 passes through the mounting frame 10. The hinge frame 32 is fixedly connected to the front end face of the plug rod 33. The connecting rod 31 is rotatably connected to the hinge frame 32. The hinge frame 32 has a certain degree of elasticity.
[0039] Both of the two opening slots 23 have inclined slots 24 at their close ends, and there is a gap between the top of the connecting mechanism 30 and the inclined slots 24; the gap between the inclined slots 24 and the connecting mechanism 30 increases the angle of movement of the disassembler, thereby reducing the difficulty of disassembly.
[0040] A retaining ring 25 is fixedly provided on the rear side wall of the opening slot 23. The front end of the retaining ring 25 is arc-shaped and can fit against the outer peripheral surface of the connecting rod 31. The hinge frame 32 has a horizontal retaining groove 60 that runs through the left and right sides and a vertical retaining groove 61 that runs through the front side. The side walls of the horizontal retaining groove 60 and the vertical retaining groove 61 can fit against the outer peripheral surface of the connecting rod 31. In the normal state, the connecting rod 31 is as follows: Figure 5 The connecting rod 31 is set at a 90-degree angle to the insertion rod 33. At this time, the connecting rod 31 is elastically locked and positioned in the opening groove 23 by the retaining ring 25. The movement of the insertion rod 33 is restricted by the connection of the hinge frame 32. When disassembling, the disassembler contacts the top of the connecting mechanism 30 through the inclined groove 24, thereby pushing the connecting rod 31 to overcome the elastic locking force at the retaining ring 25 and disengage. At the same time, the outer peripheral surface of the connecting rod 31 disengages from the horizontal retaining groove 60, so that the outer peripheral surface of the connecting rod 31 pushes the hinge frame 32 to elastically deform, so that the connecting rod 31 fits against the side wall of the vertical retaining groove 61.
[0041] Reference Figure 6 and Figure 9 A snap-fit key 34 is fixedly provided on the outer periphery of the plug-in rod 33. Two fixed sleeves 37 distributed front and rear are fixedly provided on the inner end of the mounting frame 10. The fixed sleeves 37 are rotatably engaged with the plug-in rod 33. A spring push ring 36 is connected to the front end face of the rear fixed sleeve 37. The spring push ring 36 includes an anti-slip ring that can abut against the snap-fit key 34 and a compressed spring. The front end face of the snap-fit key 34 can abut against the front fixed sleeve 37. An opening 38 is provided on the front fixed sleeve 37. The snap-fit key 34 and the opening 38 are circumferentially offset. By rotating the connecting rod 31, the plug-in rod 33 can be driven to rotate under the connection of the hinge frame 32. When the snap-fit key 34 rotates to the circumferential position where the opening 38 is located, the snap-fit key 34 will be disengaged from the mounting frame 10 by the spring force at the spring push ring 36. The sealing cover 11 can be pulled out from the mounting frame 10 after the snap-fit key 34 loses the abutment at the fixed sleeve 37.
[0042] Reference Figure 2-3The front end of the sealing cover 11 is provided with an indicator arrow 22, and a plastic frame 50 is fixed on the rear end of the sealing cover 11. The plastic frame 50 has a certain degree of elasticity and is L-shaped, abutting against the lower end of the air conditioning filter 12. The plastic frame 50 is symmetrically distributed on the left and right. A guide groove 51 is provided in the mounting frame 10. The guide groove 51 opens forward and can be inserted and matched with the plastic frame 50. During the installation process, the new air conditioning filter 12 is removed and installed on the sealing cover 11 according to the arrow and markings on the air conditioning filter 12. The indicator arrow 22 indicates the installation direction (UP) of the plastic frame 50. The markings on the air conditioning filter 12 are divided into two types: AIR FLOW and UP, which indicate the airflow direction and the installation direction, respectively. According to the different markings, different sides of the air conditioning filter 12 are installed on the sealing cover 11. The plastic frame 50 cooperates with the sealing cover 11 to abut against the front and rear ends of the air conditioning filter 12. The plastic frame 50 has a certain degree of elasticity, so it can be elastically deformed during the pulling process and adjusted according to the seat position to prevent the plastic frame 50 from getting stuck on the mounting frame 10.
