Description

Technical Field

[0001] This utility model relates to the field of automotive air intake, and in particular to a stable automotive grille air guide device. Background Technology

[0002] Most modern air intake grilles are flat. When the air intake grille is rotated, it is tilted. When a car is in motion, the air intake speed is relatively fast. This tilted air intake grille has a resistance effect on the air, resulting in a slower air intake speed and insufficient air volume for the car.

[0003] The problem solved by the existing patent authorization announcement number "CN222310378U" is to reduce intake resistance. The middle blade has a side curved surface. The curved surface on the windward side of the inclined middle blade reduces the resistance to the gas, thereby increasing the intake volume of the first intake port and increasing the intake speed.

[0004] However, the blades are not synchronized well, making it difficult to control the intake volume at the air inlet. Utility Model Content

Detailed Implementation

[0034] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0037] like Figure 1 and Figure 2 and Figure 3 As shown, a stable automotive grille air guide device includes a housing 1, a rotating assembly 2, and a blade assembly 3, with the rotating assembly 2 and the blade assembly 3 both mounted on the housing 1.

[0038] The rotating assembly 2 includes a motor 21, a swing plate 22, a support plate 23, and a conversion plate 24. The motor 21 and the support plate 23 are fixed to the housing 1 by screws. The conversion plate 24 is slidably connected to the support plate 23. The swing plate 22 and the conversion plate 24 are located on both sides of the support plate 23. The swing plate 22 has a rotating shaft 25, which is connected to the drive end of the motor 21. The motor 21 drives the rotating shaft 25 to rotate. In this example, the rotating shaft 25 is set on the support plate 23 in a rotating manner, so the rotating shaft 25 drives the swing plate 22 to rotate. The swing plate 22 rotates around the rotating shaft 25 as the center. The swing plate 22 drives the conversion plate 24 to rotate while also moving.

[0039] The cover 1 is provided with an air inlet 11. The blade group 3 includes a first blade 31 and a second blade 32. The first blade 31 and the second blade 32 are rotatably disposed in the air inlet 11. The conversion plate 24 is used to drive the first rotating plate 33 to rotate. The first blade 31 and the second blade 32 are respectively rotatably disposed. The conversion plate 24 slides to drive the first blade 31 and the second blade 32 to rotate.

[0040] During rotation, the first blade 31 has two states: closed and open air inlet 11. In the initial position, the first blade 31 completely closes the air inlet 11. When it is necessary to open the air inlet 11, the motor 21 drives the swing plate 22 to rotate. The swing plate 22 drives the conversion plate 24 to rotate and move. The first blade 31 rotates together with the conversion plate 24, so that the top and bottom of the air inlet 11 are opened, allowing gas to enter. In this example, there is also a speed sensor and a controller (not shown in the figure). The controller is connected to the speed sensor and the motor 21 respectively. Under normal circumstances, the faster the speed, the faster the engine speed, so the engine needs to calculate heat more. The controller sends a signal to the motor 21 based on the speed of the car fed back by the speed sensor. The faster the car is traveling, the more the motor 21 indirectly drives the first blade 31 to open, and more gas flows into the air inlet 11. Conversely, the slower the speed, the less the motor 21 indirectly drives the first blade 31 to open, and less gas flows into the air inlet 11.

[0041] like Figure 3 and Figure 4 and Figure 5 As shown, the conversion plate 24 is provided with a first rotating sleeve 243 and a second rotating sleeve 244. A first rotating rod 311 is provided on the first blade 31, and a second rotating rod 321 is provided on the second blade 32. The first rotating rod 311 is sleeved in the first rotating sleeve 243, and the second rotating rod 321 is sleeved in the second rotating sleeve 244. When the first rotating rod 311 rotates in the first rotating sleeve 243, the first blade 31 rotates around the first rotating rod 311. The second rotating rod 321 rotates in the second rotating sleeve 244, and the second blade 32 rotates around the second rotating rod 321.

[0042] The first blade 31 is also provided with a third rotating rod 312, the second blade 32 is provided with a fourth rotating rod 322, and the cover 1 is provided with a first rotating groove 13 and a second rotating groove 14. The third rotating rod 312 is rotatably disposed in the first rotating groove 13, and the fourth rotating rod 322 is rotatably disposed in the second rotating groove 14.

[0043] A cover plate 12 is provided on the housing 1. The cover plate 12 is fixed to the housing 1 by screws. The cover plate 12 is located on the first rotating groove 13 and the second rotating groove 14. The cover plate 12 is provided with a first cover groove 15 and a second cover groove 16. The first cover groove 15 and the first rotating groove 13 together enclose the third rotating rod 312. The second cover groove 16 and the second rotating groove 14 together enclose the fourth rotating rod 322. The first cover groove 15 is connected to the first rotating groove 13, and the second cover groove 16 is connected to the second rotating groove 14. In this way, the third rotating rod 312 is engaged between the first cover groove 15 and the first rotating groove 13, and the fourth rotating rod 322 is engaged between the second cover groove 16 and the second rotating groove 14.

[0044] The third rotating rod 312 cannot detach from the first cover groove 15 and the first rotating groove 13, the fourth rotating rod 322 cannot detach from the second cover groove 16 and the second rotating groove 14, and furthermore, the first rotating rod 311 cannot detach from the first rotating sleeve 243, and the second rotating rod 321 cannot detach from the second rotating sleeve 244.

[0045] like Figure 5 and Figure 6 and Figure 7 As shown, the conversion plate 24 has a conversion shaft 26, which is rotatably connected to the swing plate 22. When the swing plate 22 rotates, it drives the conversion plate 24 to rotate and move through the conversion shaft 26.

[0046] The upper end of the support plate 23 is provided with a groove 27. The groove 27 is used to avoid the swing of the conversion shaft 26. The groove 27 not only plays a limiting role, but also plays a role in avoiding friction between the conversion shaft 26 and the top of the conversion plate 24.

[0047] The support plate 23 is provided with a first arc-shaped hole 231 and a second arc-shaped hole 232, and the conversion plate 24 is provided with a first sliding rod 241 and a second sliding rod 242. The first sliding rod 241 is located in the first arc-shaped hole 231, and the second sliding rod 242 is located in the second arc-shaped hole 232. The first arc-shaped hole 231 and the second arc-shaped hole 232 are the same in shape and size. The conversion plate 24 drives the first sliding rod 241 and the second sliding rod 242 to rotate and move. The first arc-shaped hole 231 is the range of movement of the first sliding rod 241, and the second arc-shaped hole 232 is the range of movement of the second sliding rod 242.

[0048] The first slide bar 241 and the second slide bar 242 pass through the conversion plate 24 respectively. The first blade 31 has a first rotating plate 33, and the second blade 32 has a second rotating plate 34. The first rotating plate 33 is rotatably connected to the first slide bar 241, and the second rotating plate 34 is rotatably connected to the second slide bar 242. The first blade 31 and the second blade 32 are rotatably mounted on the support plate 23.

[0049] The first blade 31 and the second blade 32 open or close the air inlet 11 simultaneously. In the initial state, the lower end of the first blade 31 is attached to the upper end of the second blade 32, which is beneficial to the sealing of the air inlet 11.

[0050] The first slide rod 241 has a first rotating hole 245, the second slide rod 242 has a second rotating hole 246, the first rotating plate 33 has a first rotating column 313, and the second rotating plate 34 has a second rotating column 323. The first rotating column 313 is rotatably disposed in the first rotating hole 245, and the second rotating column 323 is rotatably disposed in the second rotating hole 246. In this way, the first rotating column 313 cannot fall out of the first rotating hole 245, and the second rotating column 323 cannot fall out of the second rotating hole 246. That is, the rotational connection between the first rotating plate 33 and the first slide rod 241 can be maintained, and the rotational connection between the second slide rod 242 and the second rotating plate 34 can be maintained.

[0051] The first slide rod 241 has a first limiting block 247 at its end, and the second slide rod 242 has a second limiting block 248 at its end. The first limiting block 247 abuts against the solid at the outer edge of the first arc-shaped hole 231, and the second limiting block 248 abuts against the solid at the outer edge of the second arc-shaped hole 232. In this way, the first slide rod 241 cannot fall out of the first arc-shaped hole 231, and the second slide rod 242 cannot fall out of the second arc-shaped hole 232.

[0052] Furthermore, a first protective wall 233 is provided on the outer periphery of the first arc-shaped hole 231, and a second protective wall 234 is provided on the outer periphery of the second arc-shaped hole 232. The first protective wall 233 increases the thickness of the first arc-shaped hole 231, and the second protective wall 234 increases the thickness of the second arc-shaped hole 232. The first limiting block 247 overlaps on the first protective wall 233, and the second limiting block 248 overlaps on the second protective wall 234. The first protective wall 233 can also prevent the outer edge wall of the first arc-shaped hole 231 from deforming, and the second protective wall 234 can prevent the outer edge wall of the second arc-shaped hole 232 from deforming.
