Description

Technical Field

[0001] The present invention relates to the technical field of filters, in particular to a filter for automobile air conditioners. Background Art

[0002] Since the air contains various impurities such as dust that are harmful to the human body, the ventilation system (air conditioning system) of a car is usually equipped with a car air conditioning filter to filter out impurities, preventing impurities from entering the cabin through the car's ventilation system and protecting the health of people in the car.

[0003] Automobile air conditioning filters have filter cloths to filter impurities. Generally speaking, the air inlet surface of the filter cloth is formed into a folded shape such as pleats to relatively increase the area of ​​the air inlet surface and improve the filtering efficiency.

When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0047] Please refer to Figure 1 、 Figure 2 as well as Figure 7 The present invention proposes a filter for automobile air conditioning, which is used to be set at the air inlet of the automobile's ventilation system to filter impurities in the air and prevent impurities from entering the cabin through the automobile's ventilation system. In an embodiment of the present invention, the filter for automobile air conditioning includes a frame 10 and a filter cloth 20.

[0048] The frame 10 can be made of plastic to reduce overall weight and production costs. Of course, the frame 10 can also be made of metal to provide better structural strength, which is not limited by the present invention. The frame 10 is used to be installed at the air inlet of the automobile ventilation system and connected to the ventilation system.

[0049] The filter cloth 20 has the function of filtering impurities and is disposed within the frame 10. It is understood that the filter cloth 20 is an enclosed structure, and thus has an outer surface 21 and an inner surface 22 disposed opposite each other. The outer surface 21 includes an air inlet surface 211 and an air outlet surface 212 that are connected. It is understood that the outside air will first flow through the air inlet surface 211 and then flow into the cavity enclosed by the filter cloth 20, then flow from the cavity to the air outlet surface 212, and then flow to the ventilation system. During this flow process, the filter cloth 20 can filter impurities mixed in the air.

[0050] The air inlet surface 211 has a pleated shape. This pleated shape increases the area of ​​the air inlet surface 211, thereby improving the efficiency of filtering impurities. The air inlet surface 211 includes multiple peaks 2111 and multiple troughs 2112. It is understood that the peaks 2111 are convex, while the troughs 2112 are concave. The peaks 2111 and troughs 2112 are connected and alternately arranged, giving the air inlet surface 211 a pleated shape.

[0051] In particular, along the arrangement direction of the crest sections 2111 and the trough sections 2112 , the vertices of adjacent crest sections 2111 and the bottoms of adjacent trough sections 2112 can be close to or away from each other, so that the air inlet surface 211 can be folded or unfolded accordingly.

[0052] With such an arrangement, when the density of impurities increases, the apex of the peak section 2111 and the bottom point of the trough section 2112 can be adaptively moved away, so that the air inlet surface 211 can be correspondingly expanded to adapt to the situation where the density of impurities is higher. When the density of impurities decreases, the apex of the peak section 2111 and the apex of the trough section 2112 can be adaptively moved closer, so that the air inlet surface 211 can be correspondingly blocked to adapt to the situation where the density of impurities is lower, thereby ensuring adaptability in scenarios with impurities of different densities and effectively improving the ability of the automobile air-conditioning filter to adjust the filtering effect.

[0053] It is understood that in the related art, when the density of impurities is high, the ventilation system requires a greater suction force for air, and the suction power of the ventilation system's power source is correspondingly higher. However, existing automotive air conditioning filters are unable to adapt to various scenarios with different impurity densities. This results in the ventilation system's power source needing to have a higher suction power setting to ensure sufficient air is drawn for ventilation and cooling when the impurity density is high. However, when the impurity density is low, the actual suction force required does not need to be too high. Since the suction power of the power source is constant, in this case, some power of the ventilation system's power source is wasted. It is understood that in the present invention, because the automotive air conditioning filter of the present invention can adaptively adjust the filtration effect according to the actual impurity density, that is, the filter cloth 20 can be adjusted according to different impurity densities, the suction power of the ventilation system's power source can be set relatively low, thereby effectively reducing the power consumption of the ventilation system.

[0054] Please refer to Figure 2-Figure 4 In some embodiments, the automotive air conditioning filter further includes multiple connecting rod assemblies 30. The multiple connecting rod assemblies 30 are connected and disposed within the frame 10. The air inlet surface 211 is disposed around the multiple connecting rod assemblies 30. The connecting rod assemblies 30 include a first connecting rod 31 and a second connecting rod 32. The first connecting rod 31 and the second connecting rod 32 are arranged in a cross-shaped manner. The middle portion of the first connecting rod 31 along its extension direction is rotatably connected to the middle portion of the second connecting rod 32 along its extension direction.

[0055] When the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32 increases, the apex of the peak section 2111 and the bottom point of the trough section 2112 move away from each other, thereby allowing the air inlet surface 211 of the filter cloth 20 to expand when the impurity density is high. When the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32 decreases, the apex of the peak section 2111 and the bottom point of the trough section 2112 move closer together, thereby allowing the air inlet surface 211 of the filter cloth 20 to fold when the impurity density is low. In the present invention, the connecting rod assembly 30 is used to achieve the expansion and folding of the air inlet surface 211 of the filter cloth 20, resulting in a simple structure and good results.

[0056] Of course, the present invention is not limited to this. In other embodiments, a separate driving structure may be provided to be respectively connected to the peak section 2111 and the trough section 2112 for transmission, so as to drive the top point of the peak section 2111 and the bottom point of the trough section 2112 to approach or move away from each other.

[0057] Please refer to Figure 2-Figure 4 In some embodiments, the first connecting rod 31 and the second connecting rod 32 both include a first rod body 33 and a second rod body 34 , and the first rod body 33 of the first connecting rod 31 is rotatably connected to the first rod body 33 of the second connecting rod 32 .

[0058] The second rod 34 is provided with a through-groove, and one end of the first rod 33 is passed through the through-groove to retract or extend from the through-groove. It is understood that when the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32 decreases, the first rod 33 will partially retract into the through-groove, and when the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32 increases, the first rod 33 will extend from the through-groove. In this way, regardless of whether the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32 increases or decreases, the height of the peak section 2111 and the trough section 2112 can always be maintained unchanged, thereby preventing the first rod 33 or the second rod 34 from causing the air inlet surface 211 to overextend and deform when the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32 decreases, thereby preventing damage to the filter cloth 20 caused by excessive extension and deformation of the air inlet surface 211.

[0059] Please refer to Figure 3-Figure 5 In some embodiments, the sidewalls of the first and second connecting rods 31, 32 are each provided with a limiting forming plate 35. The limiting forming plate 35 can be square and relatively regular in shape. The filter cloth 20 is wound around the limiting forming plate 35, so that the air inlet surface 211 has a pleated shape. This arrangement allows the air inlet surface 211 to maintain its pleated shape when the filter cloth 20 is wound around multiple connecting rod assemblies 30, thereby maintaining a larger area of ​​the air inlet surface 211 and ensuring efficient filtration of impurities.

[0060] Please refer to Figure 3-Figure 5 In some embodiments, the automobile air-conditioning filter further includes a sliding assembly 40, the sliding assembly 40 includes a plurality of first sliding members 41, a plurality of second sliding members 42, a first slide rail 43 and a second slide rail 44, the first connecting rod 31 is rotatably connected to the first sliding member 41 at one end along its extension direction, and is rotatably connected to the second sliding member 42 at the other end, the second connecting rod 32 is rotatably connected to the first sliding member 41 at one end along its extension direction, and is rotatably connected to the second sliding member 42 at the other end.

[0061] The first slide rail 43 and the second slide rail 44 are disposed in the frame 10 and spaced apart along the height direction of the frame 10 . A plurality of first sliding members 41 are slidably disposed on the first slide rail 43 , and a plurality of second sliding members 42 are slidably disposed on the second slide rail 44 .

[0062] In actual use, by driving one of the first sliding members 41 to approach the other first sliding member 41 adjacent to it, and controlling one of the second sliding members 42 to approach the other second sliding member 42 adjacent to it, the rotation between the first link 31 and the second link 32 can be achieved, so that the angle between the extension direction of the first link 31 and the extension direction of the second link 32 becomes smaller; and by driving one of the first sliding members 41 to move away from the other first sliding member 41 adjacent to it, and controlling one of the second sliding members 42 to move away from the other second sliding member 42 adjacent to it, the rotation between the first link 31 and the second link 32 can be achieved, so that the angle between the extension direction of the first link 31 and the extension direction of the second link 32 becomes larger, which is convenient to operate and has a simple structure.

[0063] Moreover, the setting of the first slide rail 43 is conducive to improving the movement accuracy of the first sliding member 41 when it approaches or moves away from its adjacent first sliding member 41. Similarly, the setting of the second slide rail 44 is conducive to improving the movement accuracy of the second sliding member 42 when it approaches or moves away from its adjacent second sliding member 42.

[0064] Please refer to Figure 3-Figure 6 Furthermore, each first sliding member 41 is provided with a first notch 411, and the first sliding rail 43 is provided with a first limiting boss 431. The first limiting boss 431 extends along the extension direction of the first sliding rail 43, and the first notch 411 is adapted to the first limiting boss 431. The first limiting boss 431 is inserted into the first notch 411. In this way, the first limiting boss 431 is in limiting contact with the mouth wall of the first notch 411, which can effectively prevent the first sliding member 41 from falling off the first sliding rail 43.

[0065] Each second sliding member 42 is provided with a second notch 421, and the second slide rail 44 is provided with a second limiting boss 441. The second limiting boss 441 extends along the extension direction of the second slide rail 44, and the second notch 421 is adapted to the second limiting protrusion 441. The second limiting boss 441 is inserted into the second notch 421. In this way, the second sliding member 42 can be effectively prevented from falling off the second slide rail 44 through the limiting abutment between the second limiting boss 441 and the mouth wall of the second notch 421.

[0066] Please refer to Figure 5 、 Figure 7 、 Figure 8 as well as Figure 9In some embodiments, the automobile air conditioning filter further includes a drive assembly 50, which includes a first drive member 51 and a connector 52. The first drive member 51 can be a drive component with a linear drive function, such as a cylinder, and is connected to the frame 10.

[0067] The connecting member 52 can be arranged in a T-shape, and the connecting member 52 is transmission-connected to the first driving member 51, and has two connecting ends 521, one of the two connecting ends 521 is fixedly connected to one of the first sliding members 41, and the other connecting end 521 is fixedly connected to one of the second sliding members 42. The first sliding member 41 and the second sliding member 42 connected to the connecting member 52 referred to here are arranged relative to each other in the height direction of the frame 10.

[0068] Driven by the first driving member 51, the connecting member 52 can drive the first sliding member 41 to move on the first slide rail 42, and the second sliding member 42 to move on the second slide rail 44. In this way, a single first driving member 51 can simultaneously realize the sliding of the first sliding member 41 on the first slide rail 43 and the sliding of the second sliding member 42 on the second slide rail 44, thereby realizing the change of the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32. The number of components is small, and the manufacturing cost is low.

[0069] Specifically, the first driving member 51 and the connecting member 52 are both arranged on the outside of the frame 10, and the frame 10 is provided with two sliding grooves 12. The automobile air-conditioning filter also includes two sliding members 70, one sliding member 70 is slid in a sliding groove 12, and the two sliding members 70 are connected one by one to the two driving ends of the connecting member 52. In this way, the sliding accuracy of the first driving member 51 driving the first sliding member 41 and the second sliding member 42 can be improved.

[0070] It is understood that a sensor (not shown) may also be provided at the air inlet of the ventilation system. The sensor can detect the density of impurities and provide feedback, so that the first drive member 51 can operate based on the density information and achieve automatic adjustment. For example, the sensor may be an infrared sensor or a laser sensor. The light emitted by the infrared sensor generates reflected light when it encounters impurities such as dust. The intensity of the reflected light is then detected to determine the density of the impurities. The present invention does not limit the specific type of sensor.

[0071] Please refer to Figure 1 、 Figure 2 as well as Figure 7 In some embodiments, the frame 10 has a receiving groove 13 for accommodating multiple groups of connecting rod assemblies 30, and the filter cloth 20 extends into the receiving groove 13 through the first groove 131 of the receiving groove 13, and there is a gap between the outer surface 21 and the mouth wall of the first groove 131 of the receiving groove 13.

[0072] The automobile air conditioning filter further includes a cover plate 71, which is disposed over the gap to seal the gap. This prevents outside air from flowing into the ventilation system without being filtered by the filter cloth 20 or after being completely filtered, thereby ensuring the filtering effect of the automobile air conditioning filter.

[0073] Please refer to Figure 1 、 Figure 2 as well as Figure 7 Furthermore, the cover plate 71 includes a first cover plate 711 and a second cover plate 712. The first cover plates 711 include a plurality of them, and the plurality of first cover plates 711 cooperate to cover the gap between the air inlet surface 211 and the wall of the first slot 131, thereby preventing air from flowing directly into the ventilation system without passing through the air inlet surface 211.

[0074] Each first cover plate 711 is fixedly connected to the connecting rod assembly 30. The first cover plates 711 can be made of an elastic material such as rubber. This arrangement allows adjacent first cover plates 711 to squeeze each other when the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32 decreases, allowing the first cover plates 711 to elastically deform to conform to the shape of the gap, achieving a seal. Furthermore, the contact area between the first cover plates 711 and the filter cloth 20 is provided with fluff, which has excellent deformability and sealing capabilities, effectively enhancing the sealing effect at the contact area between the first cover plates 711 and the filter cloth 20.

[0075] The second cover plate 712 may be in the shape of a long strip and covers the gap between the air outlet surface 212 and the wall of the first slot 131 , thereby preventing air from flowing directly into the ventilation system without passing through the air outlet surface 212 .

[0076] Please refer to Figure 1 、 Figure 2 as well as Figure 7 In some embodiments, the filter cloth 20 can move around the multiple groups of connecting rod assemblies 30 to change the positions of the air inlet surface 211 and the air outlet surface 212 on the outer surface 21 of the filter cloth 20. On this basis, the positions of the peak section 2111 and the trough section 2112 on the outer surface 21 of the filter cloth 20 will also change, which can prevent dust and other impurities from accumulating at fixed positions of the filter cloth 20 during long-term use. In this way, on the one hand, dust and other impurities can be evenly dispersed at various positions of the filter cloth 20, thereby effectively reducing the frequency of cleaning the automobile air-conditioning filter. On the other hand, it can prevent excessive local pressure on some positions of the filter cloth 20, which in turn causes local deformation and affects the overall use of the filter cloth 20.

[0077] Please refer to Figure 2 、 Figure 4as well as Figure 5 Furthermore, the automotive air conditioning filter further includes a rotating assembly 60, which is disposed within the frame 10 and around which the filter cloth 20 is wound. The rotating assembly 60 includes a driving pulley 61, a first driven pulley 62, a second driven pulley 63, and a compensating pulley 64. The driving pulley 61 and the first driven pulley 62 are located on one side of the filter cloth 20, while the second driven pulley 63 and the compensating pulley 64 are located on the other side of the filter cloth 20.

[0078] It can be understood that the automobile air-conditioning filter also includes a second driving member 92, which can be a driving component such as a motor. The second driving member 92 is connected to the driving wheel 61 to drive the driving wheel 61 to rotate, and then the driving wheel 61 can drive the filter cloth 20 to move. On the basis of the movement of the filter cloth 20, the first driven wheel 62, the second driven wheel 63 and the compensation wheel 64 will all rotate, so that the filter cloth 20 can move around the multiple groups of the connecting rod assemblies 30.

[0079] The compensating wheel 64 is movable relative to the frame 10. It is understood that when the density of impurities decreases, the compensating wheel 64 is able to move, thereby lengthening the length of the filter cloth 20 entering the first driven wheel 62 and the second driven wheel 63, thereby bringing the apex of the wave crest section 2111 and the bottom of the wave trough section 2112 closer together, causing the air inlet surface 211 to fold accordingly; and when the density of impurities increases, the compensating wheel 64 is able to move in the opposite direction, thereby shortening the length of the filter cloth 20 entering the first driven wheel 62 and the second driven wheel 63, thereby moving the apex of the wave crest section 2111 and the bottom of the wave trough section 2112 further apart, causing the air inlet surface 211 to unfold accordingly.

[0080] Please refer to Figure 5 、 Figure 8 as well as Figure 9 In some embodiments, a slide groove 11 is formed on the surface of the frame 10. The compensation wheel 64 includes a wheel body 641 and a sliding post 642. The sliding post 642 is fixedly connected to the wheel body 641 and can slide within the slide groove 11. The automotive air conditioning filter further includes a compression spring 93. One end of the compression spring 93 abuts the frame 10, and the other end abuts the sliding post 642 to provide tension to the sliding post 642.

[0081] It is understood that when the density of impurities decreases, the compensating wheel 64 will be able to compress the compression spring 93 to move, thereby increasing the length of the filter cloth 20 entering the first driven wheel 62 and the second driven wheel 63, so that the apex of the peak section 2111 and the bottom point of the trough section 2112 are closer together. When the density of impurities increases, the compensating wheel 64 will be able to release the compression spring 93 to move in the opposite direction, thereby shortening the length of the filter cloth 20 entering the first driven wheel 62 and the second driven wheel 63, so that the apex of the peak section 2111 and the bottom point of the trough section 2112 are farther apart. In this way, the provision of the compression spring 93 can achieve adaptive adjustment of the compensating wheel 64 and simultaneously apply a tensioning force to the compensating wheel 64, thereby keeping the filter cloth 20 in a tensioned state. In addition, the cooperation between the sliding post 642 and the chute 11 can improve the accuracy of the movement of the compensating wheel 64.

[0082] See also Figure 5 In some embodiments, the frame 10 is provided with an air outlet (not shown). The automobile air conditioning filter further includes a cleaning member (not shown), a blowing member 80 and a collecting member 90 .

[0083] The cleaning member is arranged on the outside of the frame 10 and is connected to the air outlet. The blowing member 80 is arranged in the frame 10 and is located on the inner side of the filter cloth 20. The blowing member 80 has a blowing groove 81, which is connected to the air outlet. The collecting member 90 is arranged in the frame 10 and has a collecting bin 91, wherein the blowing groove 81 has a second notch 82 facing the inner surface 22 of the filter cloth 20, so that the gas blown into the air outlet by the cleaning member can be blown toward the filter cloth 20 through the second notch 82, and then blown toward the outer surface 21 of the filter cloth 20 through the inside of the filter cloth 20, thereby blowing the impurities located on the outer surface 21 of the filter cloth 20 into the collecting bin 91.

[0084] In this way, dust and other impurities on the filter cloth 20 can be collected by the collection bin 91, preventing accumulation of impurities on the filter cloth 20. In addition, during actual use, the collection member 90 can be removed from the frame 10 to clean the dust and other impurities collected in the collection bin 91. Alternatively, a suction member can be provided and connected to the collection bin 91 to remove the dust and other impurities collected in the collection bin 91. In this way, impurities can be cleaned in a timely manner, thereby extending the service life of the automobile air conditioning filter.

[0085] Please refer to Figure 5 as well as Figure 7 In some embodiments, the filter cloth 20 further includes a cloth body 23 and a plurality of frames 24, the cloth body 23 having an air inlet surface 211 and an air outlet surface 212, wherein the plurality of frames 24 are arranged at intervals inside the cloth body 23, and some of them are located at the apex of the peak section 2111 and the bottom point of the trough section 2112.

[0086] The skeleton 24 can be made of metal to have better structural strength, so that the overall strength of the filter cloth 20 can be improved by relying on the setting of the skeleton 24, and the skeleton 24 is located at the top of the peak section 2111 and the bottom point of the trough section 2112, which can effectively prevent the wrinkled air inlet surface 211 from deforming and affecting the filtering effect of the filter cloth 20.

[0087] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
