For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0031] An embodiment of the present utility model provides an anti-sway structure for the rotating shaft of an active intake grille.
[0032] As Figure 1-8 shown, an anti-sway structure for the rotating shaft of an active intake grille, the active intake grille includes a grille 7, a main frame 1 is arranged in the middle of the grille 7, a motor 2 is arranged inside the main frame 1, drive rods 3 are arranged on both sides of the motor 2, a spline 301 is arranged on one side of the drive rod 3, and the spline 301 is fixedly connected to the motor 2. A fixing plate is arranged on the other side of the drive rod 3, the fixing plate has a thickness of 4 mm, an arc-shaped notch 302 is arranged on the fixing plate, the inner radius of the arc-shaped notch 302 is 6.1 mm, a limiting plate 303 is arranged at the bottom of the drive rod 3, the limiting plate 303 is 3 mm long and 2 mm thick. A connecting rod 4 is arranged on the drive rod 3, there are two connecting rods 4, and the two connecting rods 4 are connected by a connecting rod. A pin 401 and a number of blade pins 402 are arranged on the connecting rod 4, a raised limiting block is arranged on the pin 401, and the shape of the limiting block is like a mushroom head. The arc-shaped notch 302 on the drive rod 3 is fixedly connected to the pin 401 on the connecting rod 4. A raised limiting plate is arranged on the blade pin 402, a blade rotating rod 6 is connected to the blade pin 402, a notch is arranged on the blade rotating rod 6 and is fixedly connected to the blade pin 402. The arrangement of the limiting plate on the blade pin 402 can prevent the blade rotating rod 6 from sliding left and right and disengaging from the blade pin 402. A blade 5 is arranged on the blade rotating rod 6, one end of the blade 5 is fixedly connected to the blade rotating rod 6, and the other end is fixedly connected to the grille 7 through a rotating shaft. A rotating head is arranged on the lower side of the blade rotating rod 6, and the rotating head is fixedly connected to the main frame 1.
[0033] As Figure 9-10 shown, a support plate 101 is arranged inside the main frame 1. Above the support plate 101 is the drive rod 3. B indicates the thickness of the support plate 101, which is 2 mm. After the thickness of the support plate 101 is 2 mm, the limit plate 303 on the drive rod 3 is arranged on one side of the support plate 101. The gap between the limit plate 303 and the support plate 101 is 0.64 mm as indicated by C. The setting of the support plate 101 restricts the movement of the drive rod 3. At the same time, the limit block arranged on the pin 401 of the connecting rod 4 restricts the left and right movement of the drive rod 3. As indicated by C, the gap between the limit block of the pin 401 and the arc-shaped notch 302 on the drive rod 3 is 0.34 mm. Through the cooperation of the support plate 101 and the limit block of the connecting rod 4, the left and right movement of the drive rod 3 is restricted and the left and right swing of the drive rod 3 is also prevented.
[0034] The motor 2 is fixed in the main frame 1. The connecting rod 4 is arranged on the main frame 1. The drive rod 3 is driven by the motor 2 to rotate. Because the drive rod 3 is connected to the connecting rod 4, the connecting rod 4 is driven to rotate and shift to the other end. The blade rotating rod 6 connected to the connecting rod 4 also drives the blade rotating rod 6 to rotate. A rotating head is arranged on the lower side of the blade rotating rod 6. Because the rotating head is fixedly connected to the main frame 1, the rotating head starts to rotate in a circular motion. At this time, the blade 5 connected and arranged on the blade rotating rod 6 also starts to rotate following the bottom of the blade rotating rod 6, realizing the opening and closing of the blade 5, and thus realizing the opening and closing of the intake grille.
[0035] Through the cooperation of the main frame 1 and the connecting rod 4 with the drive rod 3, the fixing of the drive rod 3 can be conveniently realized, which is convenient for the structure to be demolded. It can effectively solve the swing problem of the rotating shafts of the drive rods 3 on both sides of the motor 2, and does not affect the structural strength. The structure is simple and the process is controllable, which is suitable for large-scale industrial production.
