[0022] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0023] 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 arranged at the air inlet of the automobile ventilation system to filter impurities in the air and prevent impurities from entering the cabin from the automobile ventilation system. In an embodiment of the present invention, the filter for automobile air conditioning includes a frame 10 and a filter cloth 20.

[0024] The frame 10 can be made of plastic material to make the overall weight lighter and the production cost lower. Of course, the frame 10 can also be made of metal material to have better structural strength, and the present invention is not limited to this. The frame 10 is used to be arranged at the air inlet of the ventilation system of the car and connected to the ventilation system.

[0025] The filter cloth 20 has the function of filtering impurities, and the filter cloth 20 is arranged in the frame 10. It can be understood that the filter cloth 20 is an enclosed structure, so the filter cloth 20 has an outer surface 21 and an inner surface 22 that are arranged opposite to each other, and the outer surface 21 includes an air inlet surface 211 and an air outlet surface 212 that are connected. It can be 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, and 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.

[0026] The air inlet surface 211 is in a pleated shape, and the pleated shape is helpful to increase the area of ​​the air inlet surface 211, thereby improving the filtering efficiency of impurities. The air inlet surface 211 includes a plurality of peak sections 2111 and a plurality of trough sections 2112. It can be understood that the peak sections 2111 are convex, and conversely, the trough sections 2112 are concave. The plurality of peak sections 2111 and the plurality of trough sections 2112 are connected and alternately arranged, so that the air inlet surface 211 is in a pleated shape.

[0027] Among them, along the arrangement direction of the crest segments 2111 and the trough segments 2112, the vertices of adjacent crest segments 2111 and the bottom points of adjacent trough segments 2112 can be close to or away from each other, so that the air inlet surface 211 is folded or unfolded accordingly.

[0028] With such a configuration, when the density of impurities increases, the apex of the peak section 2111 can be adaptively moved away from the bottom point of the trough section 2112, so that the air inlet surface 211 can be correspondingly expanded to adapt to the situation where the density of impurities is larger; and when the density of impurities decreases, the apex of the peak section 2111 can be adaptively moved closer to the apex of the trough section 2112, so that the air inlet surface 211 can be correspondingly blocked to adapt to the situation where the density of impurities is smaller, thereby ensuring adaptability in scenes with impurities of different densities and effectively improving the ability of the automotive air-conditioning filter to adjust the filtering effect.

[0029] It is understandable that in the related art, when the density of impurities is large, the suction force required by the ventilation system for air will be relatively large, and the suction power of the power source of the ventilation system will be relatively high accordingly, and the existing automobile air conditioning filter cannot adapt to various scenarios with different impurity densities, which will cause the suction power of the power source of the ventilation system to be set higher, so that when the density of impurities is large, it can ensure that enough air is extracted for ventilation and refrigeration. When the density of impurities is small, the actual required suction force does not need to be too large. Since the suction power of the power source is constant, in this case, part of the power source of the ventilation system will be wasted. It is understandable that in the present invention, since the automobile air conditioning filter of the present invention can adaptively adjust the filtering effect according to the actual density of impurities, that is, the filter cloth 20 can be adapted and adjusted according to the scenarios of impurities with different densities, the suction power of the power source of the ventilation system can be set relatively low, thereby effectively reducing the power consumption of the ventilation system.

[0030] Please refer to Figure 2-Figure 4 In some embodiments, the automobile air conditioning filter further comprises a plurality of connecting rod assemblies 30, which are connected and are all arranged in the frame 10, and the air inlet surface 211 is arranged around the plurality of connecting rod assemblies 30. The connecting rod assembly 30 comprises a first connecting rod 31 and a second connecting rod 32, and the first connecting rod 31 and the second connecting rod 32 are arranged crosswise. The middle part of the first connecting rod 31 along the extension direction thereof is rotatably connected with the middle part of the second connecting rod 32 along the extension direction thereof.

[0031] Among them, when the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32 becomes larger, the apex of the wave crest section 2111 and the bottom point of the wave trough section 2112 are far away from each other, so that when the impurity density is large, the air inlet surface 211 of the filter cloth 20 can be correspondingly unfolded. When the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32 becomes smaller, the apex of the wave crest section 2111 and the bottom point of the wave trough section 2112 are close to each other, so that when the impurity density is small, the air inlet surface 211 of the filter cloth 20 can be correspondingly folded. In the present invention, the air inlet surface 211 of the filter cloth 20 can be unfolded and folded by using the connecting rod assembly 30, and the structure is simple and the implementation effect is good.

[0032] 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 driving the top point of the peak section 2111 and the bottom point of the trough section 2112 to move closer to or away from each other.

[0033] 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 .

[0034] Among them, the second rod body 34 is provided with a penetration groove, and one end of the first rod body 33 is penetrated in the penetration groove to retract or extend out of the penetration groove. It can be 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 becomes smaller, the first rod body 33 will partially retract into the penetration 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 becomes larger, the first rod body 33 will extend out of the penetration groove, so that no matter whether the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32 becomes larger or smaller, the height of the peak section 2111 and the trough section 2112 can always be kept unchanged, thereby preventing the first rod body 33 or the second rod body 34 from causing the air inlet surface 211 to be over-extended and deformed when the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32 becomes smaller, thereby preventing the occurrence of a situation in which the filter cloth 20 is damaged due to excessive extension and deformation of the air inlet surface 211 caused by the first rod body 33 or the second rod body 34.

[0035] Please refer to Figure 3-Figure 5 In some embodiments, the side wall of the first connecting rod 31 and the side wall of the second connecting rod 32 are both provided with a limiting forming plate 35, and the limiting forming plate 35 can be arranged in a square shape with a relatively regular shape. The filter cloth 20 is wound around the limiting forming plate 35 so that the air inlet surface 211 is in a pleated shape. In this way, when the filter cloth 20 is wound around the multiple groups of connecting rod assemblies 30, the air inlet surface 211 can maintain a pleated shape, thereby maintaining a larger area of ​​the air inlet surface 211 to ensure the filtering efficiency of impurities.

[0036] 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.

[0037] The first slide rail 43 and the second slide rail 44 are disposed in the frame 10 and are arranged at intervals 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 .

[0038] In actual use, by driving one of the first sliding members 41 to approach another adjacent first sliding member 41, and controlling one of the second sliding members 42 to approach another adjacent second sliding member 42, the rotation between the first connecting rod 31 and the second connecting rod 32 can be achieved, so that the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32 becomes smaller; and by driving one of the first sliding members 41 to move away from another adjacent first sliding member 41, and controlling one of the second sliding members 42 to move away from another adjacent second sliding member 42, the rotation between the first connecting rod 31 and the second connecting rod 32 can be achieved, so that the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32 becomes larger, which is convenient to operate and has a simple structure.

[0039] Moreover, the setting of the first slide rail 43 is conducive to improving the moving 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 moving accuracy of the second sliding member 42 when it approaches or moves away from its adjacent second sliding member 42.

[0040] Please refer to Figure 3-Figure 6 Furthermore, each first sliding member 41 is provided with a first notch 411, and the first slide rail 43 is provided with a first limiting boss 431, the first limiting boss 431 extends along the extension direction of the first slide rail 43, and the first notch 411 is adapted to the first limiting boss 431, and the first limiting boss 431 is inserted into the first notch 411, so that the first sliding member 41 can be effectively prevented from falling off the first slide rail 43 through the limiting abutment between the first limiting boss 431 and the mouth wall of the first notch 411.

[0041] 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 boss 441, and 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.

[0042] Please refer to Figure 5 , Figure 7 , Figure 8 as well as Fig. 9In some embodiments, the automobile air conditioning filter further includes a driving assembly 50, and the driving assembly 50 includes a first driving member 51 and a connecting member 52. The first driving member 51 can be a driving member with a linear driving function such as a cylinder, and the first driving member 51 is connected to the frame 10.

[0043] 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.

[0044] Among them, under the drive of 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, the first sliding member 41 can slide on the first slide rail 43 and the second sliding member 42 can slide on the second slide rail 44 at the same time by using a single first driving member 51, 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, with a small number of structures and a low manufacturing cost.

[0045] 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 slidably arranged in one sliding groove 12, and the two sliding members 70 are connected one by one with 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.

[0046] It is understandable that a sensor (not shown in the figure) can also be provided at the air inlet of the ventilation system, and the sensor can detect the density of impurities to feedback density information, so that the first driving member 51 can work according to the density information to achieve automatic adjustment. Exemplarily, the type of sensor can be an infrared sensor or a laser sensor, wherein the light emitted by the infrared sensor generates reflected light when encountering impurities such as dust, and then the intensity of the reflected light is detected to determine the density of the impurities. The present invention does not limit the specific type of the sensor.

[0047] 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.

[0048] The automobile air conditioning filter further includes a cover plate 71, which is arranged at the gap to seal the gap, so as to prevent the 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.

[0049] Please refer to Figure 1 , Figure 2 as well as Figure 7 Further, the cover plate 71 includes a first cover plate 711 and a second cover plate 712. The first cover plate 711 includes a plurality of first cover plates 711, 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 the air from directly flowing to the ventilation system without passing through the air inlet surface 211.

[0050] Each first cover plate 711 is fixedly connected to the connecting rod assembly 30. The first cover plate 711 can be made of a material with elastic properties such as rubber. In this way, when the angle between the extension direction of the first connecting rod 31 and the extension direction of the second connecting rod 32 becomes smaller, two adjacent first cover plates 711 can be squeezed, so that the first cover plates 711 can be elastically deformed to adapt to the shape of the gap to achieve sealing. In addition, fluff is provided at the contact point between the first cover plate 711 and the filter cloth 20. The fluff has excellent deformation ability and sealing ability, so that the sealing effect at the contact point between the first cover plate 711 and the filter cloth 20 can be effectively improved.

[0051] The second cover plate 712 may be in the shape of a long strip, and the second cover plate 712 covers the gap between the air outlet surface 212 and the wall of the first slot 131 , thereby preventing the air from directly flowing to the ventilation system without passing through the air outlet surface 212 .

[0052] 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 cleaning frequency of the automobile air-conditioning filter. On the other hand, it can prevent excessive local pressure at some positions of the filter cloth 20, which in turn causes local deformation, thereby affecting the overall use of the filter cloth 20.

[0053] Please refer to Figure 2 , Figure 4as well as Figure 5 Furthermore, the automobile air conditioning filter further includes a rotating assembly 60, which is disposed in the frame 10, and the filter cloth 20 is also wound around the rotating assembly 60, and the rotating assembly 60 includes a driving wheel 61, a first driven wheel 62, a second driven wheel 63 and a compensation wheel 64. The driving wheel 61 and the first driven wheel 62 are located on one side of the filter cloth 20, and the second driven wheel 63 and the compensation wheel 64 are located on the other side of the filter cloth 20.

[0054] 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.

[0055] The compensation wheel 64 can move relative to the frame 10. It can be understood that when the density of impurities decreases, the compensation wheel 64 can move, so that the length of the filter cloth 20 entering the first driven wheel 62 and the second driven wheel 63 becomes longer, so that the apex of the wave crest section 2111 and the bottom point of the wave trough section 2112 are close to each other, so that the air inlet surface 211 is folded accordingly; and when the density of impurities increases, the compensation wheel 64 can move in the opposite direction, so that the length of the filter cloth 20 entering the first driven wheel 62 and the second driven wheel 63 becomes shorter, so that the apex of the wave crest section 2111 and the bottom point of the wave trough section 2112 are far away from each other, so that the air inlet surface 211 is unfolded accordingly.

[0056] Please refer to Figure 5 , Figure 8 as well as Fig. 9 In some embodiments, a slide groove 11 is provided on the surface of the frame 10, and the compensation wheel 64 includes a wheel body 641 and a sliding column 642. The sliding column 642 is fixedly connected to the wheel body 641 and can slide in the slide groove 11. The automobile air conditioning filter further includes a compression spring 93, one end of which abuts against the frame 10, and the other end abuts against the sliding column 642 to provide tension to the sliding column 642.

[0057] It is understandable that when the density of impurities decreases, the compensation wheel 64 will be able to compress the compression spring 93 to move, so that the length of the filter cloth 20 entering the first driven wheel 62 and the second driven wheel 63 becomes longer, so that the apex of the wave crest section 2111 and the bottom point of the wave trough section 2112 are close to each other; and when the density of impurities increases, the compensation wheel 64 will be able to release the compression spring 93 to move in the opposite direction, so that the length of the filter cloth 20 entering the first driven wheel 62 and the second driven wheel 63 becomes shorter, so that the apex of the wave crest section 2111 and the bottom point of the wave trough section 2112 are far away from each other. In this way, the setting of the compression spring 93 can realize the adaptive adjustment of the compensation wheel 64, and at the same time give the compensation wheel 64 a tensioning force, so that the filter cloth 20 is always in a tensioned state, and the cooperation of the sliding column 642 and the slide groove 11 can improve the accuracy of the movement of the compensation wheel 64.

[0058] See also Figure 5 In some embodiments, the frame 10 is provided with an air outlet (not shown in the figure). The automobile air conditioning filter further includes a cleaning member (not shown in the figure), a blowing member 80 and a collecting member 90 .

[0059] 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.

[0060] In this way, dust and other impurities on the filter cloth 20 can be collected by the collection bin 91, avoiding the accumulation of impurities on the filter cloth 20. In addition, in 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, or a suction member is provided and connected to the collection bin 91 through the suction member to remove the dust and other impurities collected in the collection bin 91, so that the impurities can be cleaned in time and the service life of the filter for automobile air conditioning can be extended.

[0061] 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 wave crest section 2111 and the bottom of the wave trough section 2112.

[0062] 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.

[0063] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
