[0002] With the development of the automobile industry, people's requirements for fuel saving and consumption reduction of vehicles are increasing day by day, and active air intake grilles (hereinafter referred to as AGS) are increasingly being applied to the center grid of vehicles. As the appearance of automobiles, automobile air intake grilles have also developed in a diversified manner, especially the external active air intake grilles, which have developed rapidly. They not only need to control air intake and heat dissipation, but also have aesthetic elements that conform to the trend of the times, resulting in customers' diversified requirements for external active air intake grilles. In the relevant technology, the blades of the active air intake grille driven by a single motor are generally opened and closed at the same time. In the relevant technology, the blades of the active air intake grille driven by a single motor (hereinafter referred to as AGS) are generally opened and closed at the same time. At present, the technical solution for the blades of the synchronously opened and closed AGS is as follows: the active blades are directly connected to the motor, and the transmission between the remaining driven blades and the active blades is realized through a rigid connecting rod. The clearance between the pins of all blades and the connecting rod is zero. Therefore, when the active blade opens to drive the connecting rod to move, the remaining driven blades immediately open and close synchronously with the movement of the connecting rod. The above-mentioned synchronously opened and closed AGS blade movement mode is relatively simple and cannot meet the future diversified design requirements; at the same time, the technical solution is limited in that the appearance is too flat, making the blade unable to meet the maximum air intake and appearance of AGS.

The active air intake grille according to the utility model has a simple structure, realizes the effect of gradual opening of the blades of the active air intake grille, improves the control flexibility of the active air intake grille, facilitates the adjustment of the air intake of the engine, reduces the difficulty of adjusting the air intake, improves the overall aesthetics of the vehicle, meets the design requirements of the diversified vehicle shape, and has low production cost.

[0004] However, in the above-mentioned air intake grille, only the effect of gradual opening of the blades can be achieved, and the opening angle of the blades is not changed. Therefore, the air volume cannot be changed, and it still has certain limitations. Utility Model Content

[0042] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0043] like Figure 1-6 As shown, the following embodiment discloses a vertically mounted active air intake grille.

[0044] Example 1

[0045] It comprises a grid frame 200 and a plurality of arranged blades 100, wherein the blades 100 have a connecting side 101 and a movable side 102 which are arranged opposite to each other along the length direction thereof, wherein the connecting side 101 is rotatably connected to the grid frame 200, and the movable side 102 can rotate around a rotating shaft 103 of the connecting side 101 under the action of a driving assembly 400;

[0046] It also includes a guide bracket 300, on which a guide portion is provided that can be connected to the movable side 102 and guide and limit it; under the action of the guide portion, the blade 100 can have different opening angles.

[0047] Specific reference Figure 1 As shown, the grille frame 200 is a mounting frame installed at the air outlet of the automobile, and the blades 100 are arranged and installed in the middle hollow position of the grille frame 200; at the same time, the driving component 400 is set in the middle of the grille frame 200, and the blades 100 are symmetrically arranged on both sides of the driving component 400. The driving component 400 can drive the blades 100 on both sides at the same time, so that the blades 100 on both sides are opened or closed at the same time, and the opening time is consistent.

[0048] Based on the above driving method, only one driving assembly 400 is required to drive the blades 100 on both sides, and the blades 100 on both sides can be opened or closed synchronously, thereby ensuring the aesthetics of the vehicle interior.

[0049] A guide bracket 300 is movably mounted on the grille frame 200. The guide bracket 300 is connected to the blade 100 and moves simultaneously with the blade 100 to guide the opening position of the blade 100.

[0050] Reference Figure 3 As shown, when the blades 100 are in a fully opened state, the opening angles of the blades 100 located on the same side of the driving assembly 400 are different, thereby forming air outlets of different sizes.

[0051] Based on the above configuration, when air is discharged from the air outlets, different air outlets have different air outlet volumes, thereby forming air outlet diversity.

[0052] In this embodiment, the specific implementation of the guide bracket 300 is as follows: the guide portion is a guide groove 301 provided on the guide bracket 300, and the movable side 102 of the blade 100 is provided with a guide column 110 capable of cooperating with the guide groove 301;

[0053] The plurality of guide grooves 301 have different groove lengths.

[0054] Specific reference Figure 2 and Figure 4As shown, the guide groove 301 is an inclined straight groove, and the position of the outermost end is not on the same straight line. Therefore, under the action of the guide bracket 300, when the blade 100 is opened to the maximum angle, the guide column 110 on the blade 100 is located at the outermost end of the guide groove 301, so that the movable side 102 of each blade 100 is located at a different position, and the connecting side 101 of the blade 100 is on the same straight line, so that the inclination angles of different blades 100 are different, and thus the opening angles are also different.

[0055] In this embodiment, the plurality of blades 100 at least have one calibration blade 120 with the smallest opening angle; the driving assembly 400 drives the calibration blade 120 to drive the guide bracket 300 to move, thereby causing the other blades 100 to rotate.

[0056] Preferably, in this embodiment, the blade 100 close to the side of the driving component 400 is used as the calibration blade 120, the driving component 400 drives the calibration blade 120, and the guide column 110 on the calibration blade 120 rotates, driving the guide bracket 300 to rotate, thereby driving the other blades 100.

[0057] In this embodiment, the guide post 110 on the calibration blade 120 and the guide groove 301 on the guide bracket 300 are connected without gap.

[0058] In this embodiment, the driving assembly 400 includes a driving motor 410 and a driving rod 420 arranged on both sides of the driving motor 410, and the driving rod 420 drives the calibration blade 120 to rotate; the connection method and driving method between the driving rod 420 and the calibration blade 120 are consistent with the driving method in the air intake grille in the prior art, and will not be repeated here.

[0059] Based on the above settings, by calibrating the blade 120 to drive the movement of other blades 100, the effect of gradual opening of the blades 100 of the active air intake grille is achieved, thereby improving the control flexibility of the active air intake grille, facilitating the adjustment of the air intake volume of the car, reducing the difficulty of adjusting the air intake volume, improving the overall aesthetics of the vehicle, and meeting the diverse design requirements of vehicle styling. It also has a simple structure and low production cost.

[0060] Therefore, the guide groove 301 on the guide bracket 300 connected to the calibration blade 120 is a calibration groove 302, and the calibration groove 302 is a circular groove.

[0061] In this embodiment, the specific connection method of the guide bracket 300 on the grid frame 200 is: the two ends of the guide bracket 300 are respectively a first end and a second end, the first end is connected to the calibration blade 120 and rotates around the second axis b; the second end and the grid frame 200 are limitedly connected by a connecting rod 500.

[0062] Specific reference Figure 5 As shown, short shafts are provided at both ends of the connecting rod 500, and the short shaft at the first end is limitedly connected to the grid frame 200, and the short shaft at the second end is connected to the guide bracket 300;

[0063] When the driving assembly 400 drives the calibration blade 120 to rotate, the calibration blade 120 drives the second end of the guide bracket 300 to rotate around the second axis b through the calibration groove 302. During the rotation, one end of the connecting rod 500 rotates around the central axis of the short axis on the grid bracket, and the other end of the connecting rod 500 rotates outward along with the second end of the guide bracket 300, and the other end of the connecting rod 500 makes an adaptive rotation relative to the guide bracket 300.

[0064] The central axis of the rotating shaft 103 on the calibration blade 120 is the first axis a; the connecting rod 500 rotates relative to the grid frame 200 around the third axis c, and the connecting rod 500 rotates relative to the guide bracket 300 around the fourth axis d;

[0065] When the blade 100 is opened to the maximum angle, the projections of the first axis a, the second axis b, the third axis c, and the fourth axis d on the horizontal plane are parallelograms.

[0066] Specific reference Figure 3 and Figure 5 As shown, the first axis a is located on the rotating shaft 103 of the blade 100 relative to the grid frame 200, the second axis b is located at the center of the calibration groove 302, the two ends of the third axis c and the fourth axis d are respectively the centers of the rotating shaft 103 at both ends of the connecting rod 500, a first oblique line L1 is formed between the projections of the first axis a and the second axis b, a second oblique line L2 is formed between the lenses of the third axis c and the fourth axis d, and the first oblique line L1 and the second oblique line L2 are parallel to each other and have equal lengths.

[0067] In this embodiment, the connecting rod 500 is preferably arranged on the side away from the driving assembly 400. When the blade 100 and the guide grille are moving, due to the relationship between the four rotation axes, the projection of each internal rotation position is within the above-mentioned parallelogram, that is, the movement of the blade 100 on one side in opening or closing satisfies the changing path of the parallelogram, thereby ensuring the rotation stability of the blade 100 on one side.

[0068] The specific implementation of the guide structure in this embodiment is as follows: a horizontal connecting plate 104 is extended from one side of the blade 100 connected to the guide bracket 300 , and the guide column 110 is arranged on the connecting plate 104 .

[0069] The guide column 110 is connected to a limiting component 600 , and the limiting component 600 is located above the guide bracket 300 .

[0070] Specific reference Figure 6 As shown, a guide wall 310 is formed on the outer edge of the guide groove 301 on the guide bracket 300, the guide column 110 extends from the bottom of the guide bracket 300 into the guide groove 301, and the limiting part extends from the top into the guide groove 301 and is fixed to the guide column 110. At the same time, the upper part of the guide component is limited above the guide wall 310.

[0071] Under the effect of the above structure, the guide post 110 on the blade 100 is always located in the guide groove 301 of the guide bracket 300, so that the movement of the entire air outlet grille remains stable.

[0072] Example 2

[0073] This embodiment is an improvement made on the basis of the embodiment 1, and its purpose is to provide a specific embodiment of the blade 100 angle setting method, and the specific technical solution is:

[0074] The opening angles of the plurality of blades 100 increase or decrease sequentially along the arrangement direction thereof.

[0075] The blade 100 angle is set to increase or decrease in sequence, so the size of the air outlet also increases or decreases in sequence, so that the air volume also forms a regular increase or decrease in sequence;

[0076] Compared with disordered settings, orderly settings of air volume are more in line with consumers' usage habits.

[0077] The specific implementation method of the above orderly arrangement in this embodiment is as follows: the guide portion is a guide groove 301 provided on the guide bracket 300, and the movable side 102 of the blade 100 is provided with a guide column 110 capable of cooperating with the guide groove 301;

[0078] The plurality of guide grooves 301 have different groove lengths, and the groove lengths increase or decrease sequentially along the arrangement direction of the blades 100 .

[0079] Preferably, in this embodiment, the slot length gradually increases from the center toward both sides, so that the opening angle of the blade 100 gradually increases from the side close to the drive assembly 400 toward the side away from the drive assembly 400, and the air output also gradually increases from the center of the entire air intake grille toward both sides.

[0080] Usually, the air outlet grilles on both sides are set on the front panel of the car. Therefore, the air volume blowing to the two sides is greater than the air volume in the center, so that more wind can blow to the driver's seat or the front passenger seat where the passengers are, while a small amount of wind is blown to the center, which can quickly cool down or heat up the passengers or the driver and improve the user's comfort.

[0081] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
