Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to an automotive air conditioning filter. Background Technology

[0002] The cabin air filter is an important component of a car's air conditioning system. It is primarily used to filter dust, pollen, bacteria, and other pollutants from the air to ensure fresh and healthy air inside the vehicle. Regularly replacing the cabin air filter can effectively improve air conditioning performance, reduce odors inside the car, and protect the health of the driver and passengers.

[0003] Existing automotive air conditioning filters typically consist of a mounting frame and an internal filter screen. During assembly, the filter screen is placed in the mounting frame and secured. However, when it is necessary to replace the filter screen with filters of various thicknesses and with more functions, the common fixed-thickness mounting frame is not convenient for securing filters of different thicknesses due to the different thicknesses. Therefore, the installation applicability of automotive air conditioning filters is poor. To address this, we propose an automotive air conditioning filter. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive air conditioning filter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle air conditioning filter, comprising a base plate, a lower mounting frame at the top of the base plate, an upper mounting frame at the top of the lower mounting frame, a top frame at the top of the upper mounting frame, a filter screen inside the upper mounting frame, a pressure frame fitted to the top of the filter screen, a telescopic piece fixedly connected to the top of the pressure frame, multiple pressure posts at the bottom of the top frame, multiple fixing pieces on the sidewalls of the top frame, and adjusting bolts at the top of the fixing pieces.

[0006] Preferably, a connecting piece is fixed to the side wall of the upper mounting frame, and a bolt seat fixed to the lower mounting frame is provided at the bottom of the connecting piece.

[0007] Preferably, the adjusting bolt is fitted to the top of the upper mounting frame, and multiple extension plates are fixed to the inner wall of the upper mounting frame.

[0008] Preferably, the top of the compression frame is machined with multiple positioning pits, and the bottom of the compression frame is provided with a rubber strip.

[0009] Preferably, the telescopic piece is fixed inside the upper mounting frame, and the upper mounting frame and the lower mounting frame have a cuboid structure.

[0010] Preferably, the top of the base plate has multiple mounting holes, and the bolt seat is fixed to the top of the base plate.

[0011] Preferably, the pressure post extends through the top of the extension piece and is fitted inside the upper mounting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When installing filters of various thicknesses, this utility model allows the filter to be placed between the upper and lower mounting frames and secured with bolts. Then, the pressure frame is pressed against the top of the filter. Next, multiple adjusting bolts can be turned to move the top frame downwards, causing the pressure frame to press the filter tightly. At the same time, the telescopic plate expands and contracts, thus allowing for the pressure installation of filters of various thicknesses. This facilitates the use of the upper and lower mounting frames for filters of various thicknesses, increasing the applicability of automotive air conditioning filters.

[0014] 2. When the multiple adjusting bolts are rotated, the top frame can be pressed downwards simultaneously, and multiple pressing columns can be used to press the pressing frame. This allows the top frame and the pressing columns at multiple points to apply stable pressure to the pressing frame, making the pressing frame more stable in positioning the filter screen and facilitating the long-term use of the vehicle air conditioning filter.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] Please see Figures 1-3 The illustration shows a type of automotive air conditioning filter, including a base plate 100, a lower mounting frame 110 on top of the base plate 100, and an upper mounting frame 111 on top of the lower mounting frame 110. Both the upper and lower mounting frames 111 are made of commonly available stainless steel. A top frame 130 is located on top of the upper mounting frame 111. A filter screen 120 is installed inside the upper mounting frame 111. The filter screen 120 can be made of various thicknesses of common stainless steel filter screens or composite filter screens. The top is fitted with a pressure frame 140, and the top of the pressure frame 140 is fixed with a telescopic plate 150 by bolts. The telescopic plate 150 is a commonly available corrugated and stretchable rubber sheet. The bottom of the top frame 130 is tightly welded with multiple pressure columns 122, which are made of commonly available stainless steel. The side wall of the top frame 130 is provided with multiple fixing plates 131, and the top of the fixing plates 131 is provided with adjusting bolts 132. The fixing plates 131 have threads inside that mate with the adjusting bolts 132.

[0022] Specifically, a connecting piece 113 is tightly welded to the side wall of the upper mounting frame 111. The bottom of the connecting piece 113 is provided with a bolt seat 112 that is fixed to the lower mounting frame 110, and the top of the connecting piece 113 is provided with a fastening bolt that matches the bolt seat 112.

[0023] Furthermore, the adjusting bolt 132 is fitted onto the top of the upper mounting frame 111, and multiple extension pieces 121 are tightly welded to the inner wall of the upper mounting frame 111.

[0024] Furthermore, the top of the compression frame 140 is machined with multiple positioning pits 141 that cooperate with the compression column 122, and the bottom of the compression frame 140 is provided with a rubber strip 142.

[0025] It is worth noting that the telescopic plate 150 is fixed to the inside of the upper mounting frame 111 by bolts, and the upper mounting frame 111 and the lower mounting frame 110 are rectangular parallelepiped structures.

[0026] It is worth noting that the base plate 100 has multiple mounting holes on its top, and the bolt seat 112 is fixed to the top of the base plate 100. The base plate 100 is used to install the air conditioning filter.

[0027] In addition, the pressure post 122 extends through the top of the extension piece 121 and fits into the interior of the upper mounting frame 111.

[0028] Working principle: When installing filter screens 120 of various thicknesses, the filter screen 120 can be placed between the upper mounting frame 111 and the lower mounting frame 110 and secured with fastening bolts. Then, the pressure frame 140 is pressed against the top of the filter screen 120. Next, multiple adjusting bolts 132 can be turned to move the top frame 130 downward, causing the pressure frame 140 to press the filter screen 120 tightly. At the same time, the telescopic plate 150 expands and contracts accordingly, thereby allowing for the pressure installation of filter screens 120 of various thicknesses, facilitating the use of the upper mounting frame 111. The lower mounting frame 110 is used for filters 120 of various thicknesses, increasing the applicability of the vehicle air conditioning filter. When the multiple adjusting bolts 132 are rotated, the top frame 130 can be pressed downwards simultaneously, and the multiple pressing columns 122 can be used to press the pressing frame 140. This allows the top frame 130 and the multiple pressing columns 122 to provide stable pressure on the pressing frame 140, making the pressure positioning of the pressing frame 140 on the filter 120 more stable and facilitating the long-term use of the vehicle air conditioning filter.
