[0001] The utility model relates to the technical field of automobile assembly, in particular to an automobile air-conditioning filter fixing frame. Background Art

[0002] With increasing concern about in-car air quality, filters in automotive air conditioning systems have become a crucial component in protecting the health of drivers and passengers. However, existing technologies present challenges in the installation and securing of air conditioning filters. Vehicles inevitably encounter a variety of road conditions, from potholes in cities to bumpy rural roads. Vehicle vibrations can affect filters installed in air conditioning systems. Traditional securing methods often rely on simple guide grooves and filter engagement, which is insufficient in the face of sustained vibration. The lack of multi-directional retaining mechanisms often leads to filter displacement or even detachment. Once the filter deviates from its intended position, it not only affects the proper functioning of the air conditioning system but can also allow unfiltered air to enter the vehicle cabin, severely impacting air quality. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In order to solve the problem of easy deviation and falling off of the filter in the prior art, the following technical solution is provided. Figure 1-6 ;

[0024] A car air conditioning filter fixing frame includes an upper frame 1 and a lower frame 2. The upper frame 1 is hinged to one side of the lower frame 2. The upper frame 1 and the lower frame 2 are connected on the side opposite to the hinge point by a snap assembly 3, so that the upper frame 1 and the lower frame 2 can be relatively opened and closed. After closing, the relative position is locked by the snap assembly 3, and a filter 4 is placed between the upper frame 1 and the lower frame 2. The edge of the filter 4 is clamped and fixed by the upper frame 1 and the lower frame 2.

[0025] The upper frame 1 and the lower frame 2 are rectangular structures. The upper frame 1 includes a top panel 11 and a first side panel 12. The top panel 11 is fixed above the first side panel 12. The lower frame 2 includes a bottom panel 21 and a second side panel 22. The second side panel 22 is fixed above the bottom panel 21. The cross-sections of the top panel 11 and the first side panel 12 and the cross-sections of the bottom panel 21 and the second side panel 22 are all "L"-shaped. The inner side walls perpendicular to the top panel 11 and the first side panel 12 constitute a first groove 13, and the inner side walls perpendicular to the bottom panel 21 and the second side panel 22 constitute a second groove 23. The first groove 13 and the second groove 23 constitute a rectangular groove for accommodating the edge of the filter screen 4.

[0026] Specifically, the edge of the filter screen 4 is placed in the first groove 13 and the second groove 23, the bottom panel 21 supports the four edges of the filter screen 4, the first side panel 12 and the second side panel 22 limit the filter screen 4 from the side, and the top panel 11 limits the filter screen 4 from the top, so that the position of the filter screen 4 is fully limited, making the filter screen 4 more firmly fixed and not easily shifted or fallen off due to the vibration of the car.

[0027] The top panel 11 and the first side panel 12 are an integrated structure, and the bottom panel 21 and the second side panel 22 are also an integrated structure, which facilitates their production and processing.

[0028] The surfaces of the first confined groove 13 and the second confined groove 23 are both provided with an elastic cushion layer 5. The elastic cushion layer 5 is arranged to fully fit the edge of the filter 4, effectively filling the gap between the filter 4 and the first confined groove 13 and the second confined groove 23, which can effectively prevent unfiltered air from entering the vehicle through the gap, and also prevent the dust deposited on the filter 4 from being suspended again and re-entering the air circulation system. At the same time, it blocks the vehicle vibration from being transmitted to the filter 4 to a certain extent, preventing the physical structure of the filter 4 from being damaged and shortening its life.

[0029] The locking assembly 3 includes a fixed clamping block 31, a movable clamping block 32 and a spring 33. There are two fixed clamping blocks 31 and they are symmetrically arranged on the bottom surface of the first side panel 12. Two clamping grooves 34 are provided on the top surface of the second side panel 22. The position of the clamping groove 34 corresponds to the position of the fixed clamping block 31. A movable clamping block 32 is provided at each end of the clamping groove 34. The movable clamping blocks 32 are symmetrical. The movable clamping blocks 32 are connected to the end of the clamping groove 34 through a spring 33 respectively; the two ends of the fixed clamping block 31 are in the shape of arrows protruding outward, consisting of an upper inclined surface and a lower inclined surface, and grooves 35 are respectively provided on the opposite sides of the two movable clamping blocks 32. The shape of the groove 35 matches the shape of the end of the fixed clamping block 31; the length of the clamping groove 34 is greater than the length of the fixed clamping block 31.

[0030] Specifically, after the filter screen 4 is placed and the upper frame 1 and the lower frame 2 are closed, the lower inclined surface of the fixed block 31 squeezes the top of the movable block 32, causing the movable block 32 to move toward the two ends of the slot 34 respectively. During this period, the movable block 32 squeezes the spring 33. When the lower inclined surface of the fixed block 31 is completely between the two movable blocks 32, the movable block 32 loses the squeezing and moves toward each other under the push of the spring 33, and is clamped by the groove 35 to the fixed block 31, thereby locking the upper frame 1 and the lower frame 2; when opening and closing is required, a certain force is applied to pull the upper frame 1 upward, and the upper inclined surface of the fixed block 31 squeezes the movable block 32 to move it away from each other, thereby allowing the fixed block 31 to be detached, making the overall disassembly and assembly convenient, and effectively improving the replacement efficiency of the filter screen 4.

[0031] An insert piece 7 that cooperates with the vehicle's connecting device is provided on the side of the second side panel 22 opposite to the card slot 34. A buckle 6 that cooperates with the vehicle's connecting hole is provided on the first side panel 12. Two buckles 6 are symmetrically provided. The upper frame 1 and the lower frame 2 are fixed to the vehicle ventilation system through the insert piece 7 and the buckle 6.

[0032] Working principle: the edge of the filter 4 is placed in the first groove 13 and the second groove 23, the bottom panel 21 supports the four edges of the filter 4, the first side panel 12 and the second side panel 22 limit the filter 4 from the side, and the top panel 11 limits the filter 4 from the top, so that the position of the filter 4 is fully limited and is not easily displaced or fallen off due to the vibration of the car; after the filter 4 is placed, when the upper frame 1 and the lower frame 2 are closed, the lower inclined surface of the fixed block 31 squeezes the movable blocks 32 on both sides to make them move to the two ends of the slot 34 respectively, and the fixed block 31 is clamped by the groove 35. When opening and closing, a certain force is applied to pull the upper frame 1 upward, and the upper inclined surface of the fixed block 31 squeezes the movable block 32 to make it move away from each other, thereby allowing the fixed block 31 to disengage.
