Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular, to an air conditioning grille assembly and a vehicle. Background Art

[0002] When a vehicle is in motion and there's a significant temperature difference between the inside and outside of the vehicle, a layer of fog or frost can form on the windshield. This accumulated fog and frost can obstruct the driver's vision, increasing the risk of traffic accidents. To maintain a clear field of vision and promptly remove accumulated fog and frost, vehicles typically have defrost ducts installed on the dashboard below the windshield. These ducts blow air toward the front windshield, removing the fog and frost.

[0003] Existing technologies often increase frost and mist removal speed by reducing the grille spacing in the air duct and increasing the wind speed at the duct outlet.

DETAILED DESCRIPTION

[0033] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] The first aspect of this application proposes an embodiment, such as Figure 1 A schematic diagram of the structure of an air conditioning grille assembly is shown, and Figure 2 As shown in the structural diagram of the air outlet impact structure in an air conditioning grille assembly, the air conditioning grille assembly includes:

[0035] Two fixed side walls 1, and a plurality of air outlet impact structures 2 arranged between the two fixed side walls 1;

[0036] The air outlet impact structure 2 includes: two fixed grille sheets 201, and a plurality of first air distribution fins 202 located between the two fixed grille sheets 201;

[0037] The plurality of first air distribution fins 202 are parallel to each other, and one end of the first air distribution fin 202 is connected to one fixed grid piece 201, and the other end is connected to another fixed grid piece 201:

[0038] The first air distribution fin 202 is provided with a first central air outlet 202a and a plurality of first side air outlets 202b spaced around the first central air outlet 202a.

[0039] The air conditioning grille assembly is mounted on the instrument panel at the air duct outlet and consists of two fixed sidewalls 1 and an outlet impact structure 2. The two fixed sidewalls 1 face each other and run along the inside of the air duct outlet, forming an outlet area that allows air to flow from the air duct to the front windshield. The outlet impact structure 2, located within the outlet area formed by the two fixed sidewalls 1, increases air velocity at the air duct outlet.

[0040] The air outlet impact structure 2 includes two fixed grille sheets 201 and a plurality of first air distribution fins 202 located between the two fixed grille sheets 201. The grille surfaces of the two fixed grille sheets 201 face each other, with one end of each fixed grille sheet 201 connected to one of the fixed side walls 1 and the other end connected to the other fixed side wall 1. The first air distribution fins 202 each connect one end to one of the fixed grille sheets 201 and the other end to the other fixed grille sheet 201.

[0041] The first air distribution fin 202 is provided with a plurality of air outlets for allowing air to pass through, including a first central air outlet 202a provided in the center of the first air distribution fin 202, and a plurality of first side air outlets 202b provided around the first central air outlet 202a. The first side air outlets 202b are evenly distributed around the first central air outlet 202a along the edges of the first central air outlet 202a.

[0042] As air flows from the air duct toward the front windshield, it sequentially passes through the multiple first air-dividing fins, then flows out of the front windshield through the first center air outlet and multiple first side air outlets on the first air-dividing fins. If no first air-dividing fins 202 are installed between the two fixed grille pieces 201, the outlet area allowed for air outflow is the opening area of ​​the region sandwiched between the two fixed grille pieces 201. When first air-dividing fins 202 are installed between the two fixed grille pieces, the outlet area allowed for air outflow changes from the opening area of ​​the region sandwiched between the two fixed grille pieces 201 to the sum of the areas of the first center air outlet 202a and the multiple first side air outlets 202b.

[0043] Since the first air distribution fin 202 is arranged in the area sandwiched by the two fixed grille sheets 201, its area can be approximately equal to the opening area of ​​the area sandwiched by the two fixed grille sheets 201. Therefore, the sum of the areas of the first middle air outlet 202a and the multiple first side air outlets 202b is obviously smaller than the opening area of ​​the area sandwiched by the two fixed grille sheets 201.

[0044] According to the relationship between wind speed and air outlet area, when the total amount of air is constant, the wind speed decreases as the air outlet area increases. The first air distribution fin 202 reduces the air outlet area, so that the wind speed increases due to the reduction of the air outlet area, thereby achieving the effect of greatly improving the wind speed at the air duct outlet.

[0045] Optionally, the plurality of first intermediate air outlets 202a are located on a first straight line L1 parallel to the target direction, and the areas of the plurality of first intermediate air outlets 202a decrease sequentially along the target direction;

[0046] The first side air outlets 202b of the first air distribution fins 202 are respectively located on a plurality of second straight lines L2 parallel to the target direction, and the area of ​​the first side air outlets 202b of the first air distribution fins 202 decreases sequentially along the target direction.

[0047] The target direction refers to the direction from the air inlet of the air outlet area to the air outlet of the air outlet area, wherein the air inlet is the opening of the air outlet area on the side close to the air duct, and the air outlet refers to the opening on the side away from the air duct. The first middle air outlet 202a of each first air distribution fin 202 is located on a first straight line L1 parallel to the target direction, and the first straight line L1 coincides with the straight line formed by connecting the midpoints of each first middle air outlet 202a. Each first side air outlet 202b of each first air distribution fin 202 is located on its corresponding second straight line L2 parallel to the target direction. There are multiple second straight lines L2, the number of which is the same as the number of first side air outlets 202b on the first air distribution fin 202, and the multiple second straight lines L2 coincide with the straight lines formed by connecting the midpoints of each first side air outlet 202b on different first air distribution fins 202. By arranging the first central air outlet 202a and the first side air outlet 202b in this manner, it is possible to reduce obstruction to air circulation and reduce wind loss.

[0048] The areas of the first middle air outlets 202a of the multiple first air-dividing fins 202 decrease successively along the direction from the air inlet of the air outlet area to the air outlet of the air outlet area; the areas of the multiple first side air outlets 202b of the multiple first air-dividing fins 202 decrease successively along the direction from the air inlet of the air outlet area to the air outlet of the air outlet area. This makes the area of ​​the air outlet that the air is allowed to pass through gradually decrease in the process of flowing from the air inlet of the air outlet area to the air outlet of the air outlet area, thereby gradually increasing the wind speed during the air flow.

[0049] At the same time, by utilizing the difference in area between the first middle air outlet 202a and the first side air outlet 202b, the speed of the wind flowing through the same first air distribution fin 202 can be differentiated, thereby avoiding resonance in the air outlet area and reducing wind noise at the air duct outlet.

[0050] Optionally, the air outlet impact structure 2 further includes: a second air distribution fin 203 parallel to the first air distribution fin 202;

[0051] The second air distribution fin 203 is located on the air outlet side of the plurality of first air distribution fins 202, with one end connected to one fixed grille piece 201 and the other end connected to another fixed grille piece 201;

[0052] The second air distribution fin 203 is provided with a second middle air outlet 203a and a plurality of second side air outlets 203b spaced around the second middle air outlet 203a;

[0053] The area of ​​the second middle air outlet 203a is smaller than the area of ​​the first middle air outlet 202a of the first target fin, and the area of ​​the second side air outlet 203b is larger than the area of ​​the first side air outlet 202b of the first target fin, wherein the first target fin is the first air distribution fin 202 closest to the second air distribution fin 203.

[0054] The second middle air outlet 203a is located on the first straight line L1, and the plurality of second side air outlets 203b are respectively located on corresponding second straight lines L2.

[0055] refer to Figure 2 The air outlet impact structure 2 further includes a second air distribution fin 203 parallel to the first air distribution fin 202. One end of the second air distribution fin 203 is connected to one fixed grille sheet 201, and the other end is connected to another fixed grille sheet 201. The second air distribution fin 203 is provided with a second central air outlet 203a in the central area, and a plurality of second side air outlets 203b evenly distributed around the second central air outlet 203a. The plurality of second side air outlets 203b correspond one-to-one with the plurality of first side air outlets 202b.

[0056] The second air distribution fins 203 are located on the outlet side of the plurality of first air distribution fins 202, wherein the outlet side of the plurality of first air distribution fins 202 is the side of the plurality of first air distribution fins 202 closest to the outlet of the outlet area. When air flows into the outlet area from the air inlet of the outlet area, it flows through the plurality of first air distribution fins 202 in sequence before flowing to the second air distribution fins 203. The second middle air outlet 203a is located on the first straight line L1. Air flowing out of the first middle air outlet 202a further flows into the second middle air outlet 203a. The plurality of second side air outlets 203b are respectively located on the second straight line L2 where the corresponding first side air outlets 202b are located. Air flowing out of the first side air outlet 202b further flows into the second side air outlet 203b.

[0057] The first target fin is the first air distribution fin 202 closest to the second air distribution fin 203. The area of ​​the first middle air outlet 202a on the first target fin is smaller than the areas of the first middle air outlets 202a on the remaining first air distribution fins 202. The area of ​​the first side air outlet 202b on the first target fin is smaller than the areas of the first side air outlets 202b on the remaining first air distribution fins 202.

[0058] The area of ​​the second middle air outlet 203a is smaller than that of the first middle air outlet 202a of the first target fin. That is, the area of ​​the second middle air outlet 203a is smaller than the area of ​​the first middle air outlet 202a, which is the smallest. The air flowing out of the first middle air outlet 202a on the first target fin is further accelerated by the second middle air outlet 203a as it flows through the second middle air outlet 203a, further increasing the speed of the air blowing from the air duct outlet to the front windshield.

[0059] The area of ​​the second side air outlet 203b is larger than the area of ​​the first side air outlet 202b of the first target fin, that is, the area of ​​the second side air outlet 203b is larger than the area of ​​the first side air outlet 202b, which is the smallest. Because the area of ​​the second side air outlet 203b is larger than the area of ​​the first side air outlet 202b, the air flowing out of the first side air outlet 202b on the first target fin will diffuse in all directions with the first side air outlet 202b of the first target fin as the center when flowing through the second side air outlet 203b, thereby increasing the windshield's windward area and increasing the frost removal area of ​​the air outlet point impacting the structure 2.

[0060] The second air-distributing fin 203 further accelerates the wind flowing out from the first middle air outlet 202a of the first target fin through the second middle air outlet 203a, and at the same time expands the effective range of the wind flowing out from the first side air outlet 202b of the first target fin through the second side air outlet 203b, thereby increasing the frost and fog removal speed and expanding the frost and fog removal area, thereby achieving a double improvement in removal speed and removal range.

[0061] Optionally, the air outlet impact structure 2 also includes: a guide vane 204, one end of which is connected to the second target fin, and the other end is connected to the first air distribution fin 202 adjacent to the second target fin, wherein the second target fin is the first air distribution fin 202 farthest from the second air distribution fin 203.

[0062] The second target fin is the first air distribution fin 202 farthest from the second air distribution fin 203, and is also the first air distribution fin 202 closest to the air inlet of the air outlet area. The air flowing into the air outlet area from the air inlet of the air outlet area will first pass through the first middle air outlet 202a and the first side air outlet 202b of the second target fin. Since the air flow flowing into the first middle air outlet 202a and the first side air outlet 202b of the second target fin is relatively turbulent, in order to ensure the wind direction, a guide plate 204 should be set between the second target fin and the second target fin. Through the guiding effect of the guide plate 204, the air flows along the surface of the guide plate 204 to the air outlet of the air outlet area, thereby reducing the degree of turbulence of the air flow and reducing the generation of wind noise.

[0063] At the same time, since the area of ​​the first middle air outlet 202a is usually larger than the area of ​​the first side air outlet 202b, the wind speed at the first middle air outlet 202a is lower than the wind speed at the first side air outlet 202b, and the difference in wind speed between the two is large. When the wind speeds in the same space are different, the air flow is very likely to become turbulent.

[0064] The guide plate 204 can also reduce the area difference between the first middle air outlet 202a and the first side air outlet 202b by dividing the first middle air outlet 202a, thereby reducing the wind speed difference between the two and reducing the degree of air flow turbulence.

[0065] Optionally, the shape of the plurality of first middle air outlets 202a is circular, and the shape of the second middle air outlet 203a is circular.

[0066] The circular channel has the smallest flow resistance coefficient for air. Therefore, setting the shapes of the first middle air outlet 202a and the second middle air outlet 203a to be circular can effectively reduce wind loss and maximize the effect of the air outlet point impact structure 2.

[0067] Optionally, the multiple air outlet point impact structures 2 include: multiple first air outlet point impact structures 2 located between the driver's seat and the front windshield, and a second air outlet point impact structure 2 located between the passenger seat and the front windshield.

[0068] While the vehicle is in motion, passengers in the driver's and passenger's seats need to observe the road conditions outside the vehicle through the front windshield. Therefore, to ensure maximum driving safety, the frost and fog on the front windshield in front of the driver's and passenger's seats should be removed specifically.

[0069] Based on this, the air outlet point impact structure 2 should be respectively set between the driver's seat and the front windshield, and between the passenger seat and the front windshield, so as to speed up the frost and fog removal speed in the areas corresponding to the driver's seat and the passenger seat on the front windshield.

[0070] Optionally, the air conditioning grille assembly further includes: a plurality of air guide grille pieces 3 , one end of the air guide grille piece 3 is connected to one fixed side wall 1 , and the other end is connected to another fixed side wall 1 .

[0071] The air conditioning grille assembly further includes a plurality of air guide grille pieces 3. The air guide grille pieces 3 are located in the air outlet area sandwiched between the two fixed side walls 1, with one end connected to one fixed side wall 1 and the other end connected to the other fixed side wall 1.

[0072] The air guide grille piece 3 can control the direction of the wind, so that the wind flowing out of the air duct outlet is blown toward the front windshield in a directional manner, thereby improving the removal efficiency of frost and fog.

[0073] Optionally, a plurality of air guide grille pieces 3 are distributed on both sides of the central plane of the air conditioning grille assembly and are inclined in a direction away from the central plane;

[0074] The angle between the air guide grille piece 3 and the central plane increases as the distance between the air guide grille piece 3 and the central plane increases.

[0075] The center plane of the air conditioning grille assembly is a plane equidistant from both ends of the grille assembly. The air guide grille fins 3 are arranged on either side of the center plane, tilted away from the center plane. The greater the distance between the air guide grille fins 3 and the center plane, the greater the tilt. The greater the tilt of the air guide grille fins 3, the closer the air, which is blown out of the air duct outlet through the air guide grille fins 3, is blown toward the ends of the front windshield.

[0076] Therefore, the air guide grille pieces 3 arranged in such a fan-shaped arrangement shape can expand the wind receiving range of the front windshield and expand the frost and fog removal area of ​​the air conditioning grille assembly.

[0077] Optionally, the air conditioning grille assembly further includes: a plurality of first connection ends 4 connected to a side of one fixed side wall 1 away from the air outlet point impact structure 2, and a plurality of second connection ends 5 connected to a side of another fixed side wall 1 away from the air outlet point impact structure 2, wherein the plurality of first connection ends 4 and the plurality of second connection ends 5 are staggered in the length direction of the fixed side wall 1;

[0078] The air conditioning grille assembly is connected to the instrument panel via a plurality of first connection ends 4 and a plurality of second connection ends 5 .

[0079] In order to improve the disassembly and assembly of the air conditioning grille assembly and facilitate the maintenance and replacement of the air conditioning grille assembly, multiple connection ends can be set on the air conditioning grille assembly and connected to the instrument panel through the connection ends.

[0080] Specifically, the connection ends on the air conditioning grille assembly include multiple first connection ends 4 connected to the side of a fixed side wall 1 away from the air outlet impact structure 2, and multiple second connection ends 5 connected to the side of another fixed side wall 1 away from the air outlet impact structure 2.

[0081] In an optional embodiment, the first connection end 4 may be a plug connector, and the second connection end 5 may be a connection end provided with a snap-in slot. Accordingly, the instrument panel should be provided with a plug-in slot adapted to the first connection end 4 and a snap-in connector adapted to the second connection end 5.

[0082] When installing the air conditioning grille assembly on the dashboard, first insert the plug connector of the first connecting end 4 into the plug slot on the dashboard, and then snap the card connector on the dashboard into the card slot of the second connecting end 5, and finally realize the connection between the air conditioning grille assembly and the dashboard assembly through the first connecting end 4 and the second connecting end 5.

[0083] Multiple first connecting ends 4 and second connecting ends 5 are evenly distributed on opposite sides of the air conditioning grille assembly. In order to optimize the force applied when the air conditioning grille assembly is connected to the instrument panel, the first connecting ends 4 and second connecting ends 5 should be staggered along the length of the fixed side wall 1 so that the first connecting end 4 is located in the area between two adjacent second connecting ends 5.

[0084] In addition, connecting ends are provided at both ends and the midpoint of the air conditioning grille assembly to further enhance the connection strength between the air conditioning grille assembly and the instrument panel.

[0085] Specifically, the connection ends at both ends of the air conditioning grille assembly may be provided with a snap-in slot for connecting to a snap-in connector on the instrument panel. The connection end at the midpoint of the air conditioning grille may be provided with a connection hole for connecting to the instrument panel via a bolt disposed in the connection hole.

[0086] The present application proposes an air conditioning grille assembly and a vehicle, wherein the air conditioning grille assembly is provided with an air outlet impact structure 2. The air outlet impact structure 2 includes a plurality of first air distribution fins 202 provided with a first central air outlet 202a and a first side air outlet 202b. When air flows through the air outlet impact structure 2, it needs to pass through the plurality of first air distribution fins 202 in sequence. After passing through the first central air outlet 202a and the plurality of first side air outlets 202b on the first air distribution fins 202, it flows to the front windshield. According to the relationship between wind speed and air outlet area, when the total amount of air is constant, the wind speed decreases as the air outlet area increases. Based on this, the first air distribution fin 202 provided in the present application blocks part of the original air outlet area through the wing surface of the first air distribution fin 202, except for the first middle air outlet 202a and the first side air outlet 202b, thereby reducing the air outlet area allowing air to flow out, and increasing the wind speed due to the reduction of the air outlet area, ultimately achieving the effect of greatly improving the wind speed at the air duct outlet.
