[0010] In the above air intake grille, the shapes of the air inlets and the blades are both triangular.

[0011] In the air intake grille, the guide groove comprises a first straight section, a spiral section and a second straight section, the spiral section is located between the first straight section and the second straight section, the first straight section, the spiral section and the second straight section are integrally communicated, when the guide column is located in the first straight section, the blade covers the air inlet and the air passage area is minimum, when the guide column is located in the second straight section, the blade exposes the air inlet and the air passage area is maximum.

[0012] In the air intake grille, along the axial direction of the pull rod, the distance between adjacent two blades is a blade spacing, the distance between adjacent two guide columns is a guide column spacing; the blade spacing corresponds to the guide column spacing, and when the pull rod drives the blades to rotate, the rotation of at least two blades is asynchronous.

[0013] In the air intake grille, each blade spacing is the same, and the guide column spacing is different from the blade spacing.

[0014] In the air intake grille, the pull rod comprises a first end and a second end, the first end is connected with the driving assembly; the guide column comprises a critical guide column; the guide column spacing between the critical guide column and the first end is a first guide column spacing, each first guide column spacing is the same and greater than the blade spacing; the guide column spacing between the critical guide column and the second end is a second guide column spacing, each second guide column spacing is the same and smaller than the blade spacing.

[0018] Secondly, an automobile comprises the air intake grille.

[0019] Compared with the prior art, the air intake grille has the following beneficial effects:

[0020] 1. By driving the pull rod to move through the drive assembly and allowing the guide post to slide in the guide groove, the blade rotates around the pull rod, precisely controlling the rotation angle of the blade and thus adjusting the ventilation area corresponding to the air inlet.

[0021] 2. The triangular shape of the air inlet and blades helps to gradually change the size of the air inlet ventilation area.

[0022] 3. By gradually rotating the blades to open or close the air intake, the air intake area can be adjusted to control the airflow, which can more accurately control the engine operating temperature and thus achieve more precise thermal management.

[0023] 4. The change in air inlet ventilation area corresponding to the unit displacement of the pull rod first increases from small to large and then decreases from large to small. Therefore, the temperature control is more accurate in the first and last stages.

[0024] 5. The motor can drive the crank to rotate and drive the connecting rod to move linearly through the strip groove, thereby driving the tie rod to move, converting the rotational motion of the motor into the linear motion of the tie rod. Attached Figure Description

[0047] The grille base 100 comprises at least one air inlet group, and each air inlet group comprises a plurality of air inlets 110.

[0048] The number of the pull rods 200 is the same as that of the air inlet groups, and the pull rods 200 are limited to move along the axial direction of the pull rods 200, and the pull rods 200 comprise a plurality of guide columns 210.

[0049] The number of the blades 300 is the same as that of the air inlets 110 and corresponds to the air inlets 110 one by one, and the blade 300 comprises a rotating part 310, and the rotating part 310 comprises a guide groove 320; each blade 300 is connected to the pull rod 200 through the rotating part 310 and can rotate relative to the air inlet 110 to adjust the air passage area of the corresponding air inlet 110; the number of the blades 300 is the same as that of the guide columns 210, and each guide column 210 is located in the guide groove 320 of each blade 300.

[0051] In the embodiment, the rotation angle of the vane 300 is precisely controlled by driving the pull rod 200 to move and the guide column 210 to slide in the guide groove 320, so as to adjust the air passage area of the corresponding air inlet 110.

[0052] Preferably, the air inlets 110 and the vane 300 are triangular in shape, which helps to gradually change the size of the air passage area of the air inlet 110.

[0058] Specifically, when the driving assembly 400 drives the pull rod 200 to move to the right, the blades 300 located at the critical guide column 211 first rotate to open the corresponding air inlet 110, then the blades 300 located between the critical guide column 211 and the two ends of the pull rod 200 rotate to open the corresponding air inlet 110, and finally the blades 300 located at the first end and the second end of the pull rod 200 rotate to open the corresponding air inlet 110, thereby realizing the water flow effect that the middle blades are opened first, and then the blades on both sides are opened in sequence.

[0059] In the embodiment, the change amount of the air passage area of the air inlet 110 corresponding to the unit displacement amount of the pull rod 200 first changes from small to large and then changes from large to small, as shown in the following table: Figure 14 Therefore, the temperature control in the first and last two stages is more accurate.
