[0053] With the continuous development of the automotive industry in recent years, the pursuit of automotive styling has become more and more diverse. The vehicle manufacturer improves the diversity of the overall front styling and the aerodynamic performance by advancing the intake grille blades. In the existing above-mentioned solutions, a linkage mechanism is often arranged between multiple blades, and a single one of the blades is driven to rotate by a driving motor, and then all the blades are driven to rotate synchronously. However, the above structure requires that the rotation paces of all the blades be consistent.

[0054] The present utility model provides a solution that can meet the inconsistent opening paces of the blades to meet the differential opening of the blades. However, in the above-mentioned solution, a linkage mechanism is used to drive the rotation of the blades. However, how to set the connection mode between the structures of the linkage mechanism is an urgent problem to be solved.

[0055] Please refer to Figures 1 to 4 , the present utility model also proposes an intake grille module 100. A linkage mechanism 40 is arranged in the intake grille module. The driving motor 20 drives the linkage mechanism 40 to move, and then drives the rotation of the blades 30, thereby realizing the opening and closing of the grille holes of the grille frame 10.

[0056] Please continue to refer to Figures 2 to 4 , the present utility model proposes a linkage mechanism 40. The linkage mechanism 40 includes a main shaft arm 1, two connecting rods 2, and a connecting structure 3.

[0057] The main shaft arm 1 is formed with two connecting arms 11. The two connecting arms 11 are oppositely arranged in the radial direction of the main shaft arm 1, and each connecting arm 11 extends along the axial direction of the main shaft arm 1.

[0058] One end of each connecting rod 2 is rotatably connected to one of the connecting arms 11.

[0059] The connecting structure 3 is disposed between the connecting arm 11 and the corresponding connecting rod 2, and / or the connecting structure 3 is used to be disposed between the connecting rod 2 and the drive shaft 301 of the corresponding blade 30.

[0060] In the technical solution of the present utility model, two connecting arms 11 are formed on the main shaft arm 1. Each connecting arm 11 is connected to a connecting rod 2, and the connecting rod 2 is connected to a blade 30. When the main shaft arm 1 rotates, the rotation paces of the two connecting arms 11 can be set to be inconsistent, so as to realize the differential opening of the two blades 30. The connecting structure 3 realizes the rotational connection between the two structures and can also be axially limited, improving the stability of the link mechanism 40 during the movement process, making the matching state of the opening and closing of the blade 30 better, and increasing the stability of air intake.

[0061] It should be noted that one end of the main shaft arm 1 away from the two connecting arms 11 is used to drive and connect the drive motor 20; the other end of each connecting rod 2 is used to be rotatably connected to the drive shaft 301 provided on the blade; the connecting structure disposed between the connecting arm 11 and the corresponding connecting rod 2 is used to enable relative rotation between the connecting arm 11 and the corresponding connecting rod 2 and can be axially limited in the axial direction of the connecting arm 11; the connecting structure disposed between the connecting rod 2 and the drive shaft 301 of the corresponding blade 30 is used to enable relative rotation between the connecting rod 2 and the drive shaft 301 of the blade 30 and can be axially limited in the axial direction of the drive shaft 301 of the blade 30.

[0062] It can be understood that two blades 30 are provided in the intake grille module 100. The two blades 30 are used to jointly open or close the grille opening of the grille frame 10. The two blades 30 can be arranged in the up-down direction, or in the left-right direction, etc.

[0063] The inconsistency of the two blades 30 can be manifested as a difference in timing, such as opening one of the blades 30 first and then opening the other blade 30. Of course, it can also be a difference in opening direction, such as the upper blade 30 opens outwards and the lower blade 30 opens inwards; or, the upper blade 30 opens inwards and the lower blade 30 opens outwards, etc., all of which are within the scope of protection of the present utility model.

[0064] Regarding the connection between the main shaft arm 1 and the connecting rod 2, in some embodiments, see Figure 5 The connecting structure 3 includes a first shaft portion 31 provided on one of the connecting arm 11 and the connecting rod 2, and a first hole portion 32 provided on the other of the connecting arm 11 and the connecting rod 2, and the first shaft portion 31 is rotatably installed in the first hole portion 32.

[0065] A first clamping rib portion 311 is provided at the head of the first shaft portion 31, and an avoidance groove 321 is provided on the inner wall surface of the first hole portion 32. The side wall of the avoidance groove 321 is set to penetrate, and the first clamping rib portion 311 is clamped at the edge of the first hole portion 32. The first shaft portion 31 and the first hole portion 32 have a relative rotation stroke. In the rotation stroke, the first clamping rib portion 311 and the avoidance groove 321 are always staggered.

[0066] That is, the connecting arm 11 and the connecting rod 2 are rotated by the matching of the shaft hole, and the axial limitation is achieved by the clamping effect of the first clamping rib portion 311 .

[0067] It should be noted that the width and depth of the avoidance groove 321 are greater than the width and height of the first clamping rib portion 311. Thus, when installing the connecting arm 11 and the connecting rod 2, the first clamping rib portion 311 needs to be installed in the avoidance groove 321. After the head of the first shaft portion 31 extends out of the first hole portion 32, the first shaft portion 31 and the first hole portion 32 are rotated relative to each other so that the first shaft portion 31 and the first hole portion 32 are staggered at a preset angle, and then the connecting rod 2 and the drive shaft 301 of the blade 30 are assembled.

[0068] The preset angle needs to be greater than the rotation angle of the first shaft portion 31 and the first hole portion 32 within their relative rotation range after installation. In this way, during the entire activity of the connecting rod mechanism 40, the first clamping rib portion 311 is always offset from the avoidance groove 321, playing the role of axial clamping limit.

[0069] When it is necessary to remove the link mechanism 40, the connection structure 3 between the connecting rod 2 and the drive shaft 301 of the blade 30 can be removed first, and then the connecting rod 2 can be rotated so that the first rib portion 311 and the avoidance groove 321 are arranged in alignment. At this time, the separation of the connecting arm 11 and the connecting rod 2 is realized, and the disassembly and assembly operations are very simple.

[0070] In some embodiments, there are multiple corresponding first rib portions 311 and avoidance grooves 321, which are respectively arranged in the circumferential direction of the first shaft portion 31. Through the clamping action of the multiple first rib portions 311, the connection between the connecting arm 11 and the connecting rod 2 is more reliable, and the movement of the link mechanism 40 is more stable.

[0071] In some embodiments, please refer to Figure 6 and Figure 7 , the connection structure 3 includes a second shaft portion 33 provided on one of the connecting rod 2 and the drive shaft 301 of the blade 30, and a second hole portion 34 provided on the other of the connecting rod 2 and the drive shaft 301 of the blade 30. The second shaft portion 33 is rotatably installed in the second hole portion 34;

[0072] A notch 331 is provided at the head of the second shaft portion 33 to form two elastic arm portions opposite to each other in the radial direction of the second shaft portion 33. A second rib portion 332 is provided on at least one of the elastic arm portions, and the second clamping portion is used for clamping at the edge of the second hole portion 34.

[0073] That is, the connecting rod 2 and the drive shaft 301 of the blade 30 are rotated by means of shaft-hole cooperation, and axial limitation is achieved through the clamping action of the second rib portion 332.

[0074] A notch 331 is provided at the head of the second shaft portion 33 to form two elastic arm portions opposite to each other in the radial direction of the second shaft portion 33. The distance between the two elastic arm portions can be reduced after deformation so that the two elastic arms can pass through the second hole portion 34, and then the second rib portion 332 extends out of the second hole portion 34 to achieve clamping at the edge of the second hole portion 34.

[0075] When assembling the connecting rod 2 and the drive shaft 301 of the blade 30, first squeeze the two elastic arm portions so that the two elastic arm portions deform towards each other and then pass through the second hole portion 34. After the second rib portion 332 extends out of the second hole portion 34, the second rib portion 332 abuts and limits at the edge of the second hole portion 34 to realize the installation of the connecting rod 2 and the drive shaft 301 of the blade 30. The installation is simple and convenient.

[0076] In some embodiments, referring to Figure 4 , the two connecting arms 11 include a first connecting arm 11a and a second connecting arm 11b, and the first connecting arm 11a protrudes axially along the main shaft arm 1 beyond the second connecting arm 11b.

[0077] The two connecting rods 2 include a first connecting rod 2a and a second connecting rod 2b, and the length of the first connecting rod 2a is shorter than the length of the second connecting rod 2b.

[0078] The first connecting arm 11a is connected to the first connecting rod 2a, and the second connecting arm 11b is connected to the second connecting rod 2b.

[0079] When the length of the first connecting arm 11a is longer than the length of the second connecting arm 11b, the first connecting rod 2a and the second connecting rod 2b can be arranged staggeredly, reducing the risk of interference between structures and improving the stability of the movement of the link mechanism 40.

[0080] In addition, by reasonably allocating the lengths of the first connecting arm 11a, the second connecting arm 11b, the first connecting rod 2a and the second connecting rod 2b, the inconsistent movement paces of the two blades 30 can be well achieved.

[0081] One end of the main shaft arm 1 where the two connecting arms 11 are provided is a cantilever end. In order to further improve the stability of the movement of the link mechanism 40, in some embodiments, referring to Figure 8 , a connecting convex portion 12 further protrudes at one end of the main shaft arm 1 where the two connecting arms 11 are provided, and the connecting convex portion 12 is located on the rotation axis of the main shaft arm 1.

[0082] The link mechanism 40 further includes a limit bracket 4, the limit bracket 4 is used for fixedly connecting to the grille frame 10, a connecting jack is formed on the limit bracket 4, and the connecting convex portion 12 is rotatably inserted into the connecting jack.

[0083] Connected to the connecting convex portion 12 through the connecting jack on the limit bracket 4, providing support for the other end of the main shaft arm 1 that is suspended relative to the drive motor 20, thereby improving the rotational stability of the main shaft arm 1, and further improving the opening and closing control accuracy of the drive motor 20 for the blades 30.

[0084] It should be noted that the limit bracket 4 is fixedly connected to the grille frame 10, which can be achieved through a threaded connection structure 3 or a clamping structure or other connection methods.

[0085] For the main shaft arm 1, it can be integrally formed, and the material can be set as plastic material and formed by integral injection molding.

[0086] Please refer to Figure 8 and Figure 9 For the axial limit of the main shaft arm 1, a limit bracket 4 is provided at one end of the main shaft arm 1, and a limit rib portion 13 is provided at the other end of the main shaft arm 1. Through the combined limiting action of the limit bracket 4 and the limit rib portion 13, the axial limit of the main shaft arm 1 is realized, thereby improving the stability of its rotation.

[0087] In some embodiments, a limit rib portion 13 is provided at one end of the main shaft arm 1 away from the two connecting arms 11. The limit rib portion 13 extends in a direction away from the two connecting arms 11 for abutting against the housing of the drive motor 20. With this setting, by forming the limit rib portion 13 on the main shaft arm 1, no additional machining is required. When the main shaft arm 1 is injection molded, it can be injection molded together, simplifying the setting of parts.

[0088] The connection method between the main shaft arm 1 and the drive motor 20 mainly uses spline connection to achieve torque transmission. In some embodiments, the main shaft of the drive motor 20 is hollow, and an internal spline is provided inside the main shaft. A spline shaft portion 15 is provided on the main shaft arm 1, and the spline shaft portion 15 is inserted into the main shaft to realize torque transmission between the drive motor 20 and the main shaft arm 1.

[0090] In some embodiments, a plurality of weight reduction grooves 14 are provided on the outer surface of the main shaft arm 1. Through the setting of the weight reduction grooves 14, on the basis of not affecting the structural strength of the main shaft arm 1, materials are saved, making the formed main shaft arm 1 lighter and also facilitating the operator to assemble the link mechanism 40.
