Description

Technical Field

[0001] The utility model relates to the field of automobiles, and in particular to an active air intake grille with multiple groups of blades folded and opened synchronously. Background Art

[0002] For traditional fuel vehicles, after the vehicle is started, the active closed air intake grille will automatically adjust the opening and closing of the blades according to the temperature of the engine, so as to achieve the effect of rapid warm-up and enable the engine to enter the best working state in the shortest time. During high-speed driving, if the air intake grille is always open, it will increase wind resistance and increase fuel consumption. If the air intake grille is closed in time, it will bring a lower drag coefficient to the vehicle, thereby improving vehicle stability and fuel economy. For new energy vehicles, the active air intake grille can increase the range by reducing the drag coefficient during high-speed driving.

[0003] At present, the opening and closing directions of most active grille blades are generally consistent, but with the development of automobile styling, active grilles are gradually taking on some appearance functions. In order to pursue a better opening visual effect, some new models will consider changing the opening direction of the grille, such as making the two sets of blades move in opposite directions to open. However, in the existing technology, the arrangement of two sets of blades moving in opposite directions requires the blades with different movement directions to be separated separately, resulting in the need to set an independent rotation axis for each blade, which occupies a large layout space and affects the overall layout.

Therefore, the features defined as "first", "second", etc. can explicitly or implicitly include one or more features.

[0030] See also Figure 1 and Figure 3 As shown, an embodiment of the utility model provides an active air intake grille with multiple groups of blades that are synchronously folded and opened, including a grille frame 1, a drive assembly 2 and multiple groups of blade assemblies 3; the grille frame 1 is provided with an air inlet 11 for air flow to pass through, the blade assembly 3 is rotatably mounted on the grille frame 1, the drive assembly 2 is transmission-connected to the blade assembly 3, and the drive assembly 2 is used to drive the blade assembly 3 to rotate, so that the blade assembly 3 can switch back and forth between an open state and a closed state to open or close the air inlet 11 and adjust the air flow through the air inlet 11.

[0031] like Figure 5 As shown, each set of blade components 3 in the embodiment of the utility model includes a first blade 31, a second blade 32, a shaft sleeve 33 and a rotating shaft 34. Among them, the rotating shaft 34 is rotatably mounted on the grid frame 1, the second blade 32 is fixedly mounted to the rotating shaft 34, the first blade 31 is fixedly mounted to the shaft sleeve 33, and the shaft sleeve 33 is rotatably sleeved on the rotating shaft 34, so that the first blade 31 can be coaxially arranged with the second blade 32, so as to achieve the purpose of reducing the blade arrangement space. The shaft sleeve 33 and the rotating shaft 34 of each set of blade components 3 are respectively connected to the driving component 2 in a transmission manner, and the shaft sleeve 33 and the rotating shaft 34 can rotate synchronously in opposite directions under the drive of the driving component 2, and drive the first blade 31 and the second blade 32 to rotate synchronously in opposite directions, so that multiple sets of blade components 3 can be opened or closed synchronously, which not only improves the opening and closing efficiency of the blades, but also provides a better visual effect.

[0032] Specifically, the embodiment of the utility model has a strip opening 35 (the width of the strip opening 35 needs to be smaller than the inner diameter of the sleeve 33) on the side wall of the sleeve 33 along its length direction, and a corresponding assembly flat position 36 adapted to the strip opening 35 is formed on the rotating shaft 34 to ensure that the rotating shaft 34 can be inserted into the sleeve 33 from the strip opening 35.

[0033] like Figure 6 As shown, during assembly, the assembly flat position 36 of the rotating shaft 34 is aligned with the strip opening 35 on the sleeve 33, and the rotating shaft 34 can be inserted into the sleeve 33 from the strip opening 35. At this time, the second blade 32 will be inclined outward at a certain angle relative to the first blade 31; the blades are rotated inwardly so that the first blade 31 and the second blade 32 are in a straight state (i.e., the closed state of the blade assembly 3), and the assembly of the blade assembly 3 can be completed. At this time, there will be a certain angle between the assembly flat position 36 and the strip opening 35 (such as Figure 7 As shown); and because the blade assembly 3 is flipped inward to open, which is opposite to the inclination direction of the blade when it is assembled, when the blade assembly 3 switches back and forth between the open state and the closed state, there is always a certain angle between the assembly flat position 36 and the strip opening 35, so that the shaft sleeve 33 can be interlocked with the rotating shaft 34 to ensure that the shaft sleeve 33 will not fall out.

[0034] In order to enhance the overall rigidity of the blade assembly 3, the second blade 32 can be integrally formed with the rotating shaft 34 by a process such as, but not limited to, double-color injection molding. For reference, the rotating shaft 34 can be made of, but not limited to, stainless steel, and the second blade 32 can be made of, but not limited to, PA6-GF30 / PC+ABS. Similarly, the first blade 31 is preferably also integrally formed with the shaft sleeve 33, and the material of the first blade 31 is consistent with that of the second blade 32.

[0035] Furthermore, in the embodiment of the utility model, multiple groups of mounting parts for mounting the blade assembly 3 are arranged at intervals on the grid frame 1, and each group of mounting parts includes a circular plug hole and a semicircular slot arranged opposite to each other, and a pressing plate 12 is detachably mounted on the open side of the semicircular slot. Figure 4 As shown, after the upper and lower ends of the rotating shaft 34 are rotatably inserted into the circular insertion hole and the semicircular slot respectively, the pressure plate 12 is installed to the open side of the semicircular slot. The pressing plate 12 can be used to detachably restrict the rotating shaft 34 in the semicircular slot, thereby installing the assembled blade assembly 3 to the grille frame 1.

[0036] In addition, as an optional implementation, Figure 2 and Figure 8As shown, the driving assembly 2 in the embodiment of the utility model includes a driving motor 21, a driving connecting rod 22, a first connecting rod 23, a second connecting rod 24, a first connecting bracket 25 and a second connecting bracket 26. Among them, the driving motor 21 is fixedly mounted on the grid frame 1 through mounting parts such as the mounting bracket 13, and the output shaft of the driving motor 21 is connected to the middle section of the driving connecting rod 22 through a spline or other connecting structure; one end of the first connecting rod 23 is rotatably connected to one end of the driving connecting rod 22, and the other end of the first connecting rod 23 is rotatably connected to the first connecting bracket 25; one end of the second connecting rod 24 is rotatably connected to the other end of the driving connecting rod 22, and the other end of the second connecting rod 24 is rotatably connected to the second connecting bracket 26; each set of blade assemblies 3 is provided with a transmission arm 37 on the shaft sleeve 33 and the rotating shaft 34, and the shaft sleeve 33 and the rotating shaft 34 are respectively connected to the first connecting bracket 25 and the second connecting bracket 26 through corresponding transmission arms 37. When the driving motor 21 drives the driving connecting rod 22 to rotate, the driving connecting rod 22 can drive the first connecting rod 23 and the second connecting rod 24 at both ends to drive the first connecting bracket 25 and the second connecting bracket 26 to move synchronously in opposite directions, thereby driving the sleeve 33 and the rotating shaft 34 to rotate synchronously in opposite directions, thereby realizing the synchronous opening or closing of multiple groups of blade assemblies 3.
