Detailed implementation mode
[0027] The following are specific embodiments of the present invention in combination with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.
[0028] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, the directional indications will also change accordingly.
[0029] As Figures 1-8 shown, an active air intake grille for an automobile includes a frame 100. An upper air intake grille 101 and a lower air intake grille 102 are provided on the frame 100. The upper air intake grille 101 includes upper blades 103 rotatably connected to the frame 100. The lower air intake grille 102 includes at least one lower blade 104 rotatably connected to the frame 100. A driver 106 is also provided on the frame 100 and is drivingly connected to the upper blades 103 or at least one lower blade 104. A synchronous driving assembly is provided between the upper blades 103 and the lower blades 104. When the driver 106 works, the upper blades 103 and the lower blades 104 are synchronously unfolded / closed.
[0030] In this embodiment, when the driver 106 drives the upper blades 103 or at least one lower blade 104 to rotate, the synchronous driving assembly synchronously drives the lower blades 104 or the upper blades 103 to rotate synchronously, to perform unfolding / closing or multi-angle hovering, realizing the linkage between the upper and lower blades 104 directly. Thus, the synchronous rotation of the blades in the upper air intake grille 101 and the lower air intake grille 102 can be achieved with only one driver 106, simplifying the overall structure inside the grille and reducing the product cost. Moreover, the entire air intake grille is driven by one driver 106, and there will be no logical problems when two drivers 106 are used for synchronous control driving, improving the stability and service life of the product during use.
[0031] Preferably, the synchronous drive assembly includes a synchronous rod 105 movably arranged on the frame 100. The synchronous rod 105 is hinged to the ends of all the lower vanes 104. The driver 106 is drivingly connected to at least one lower vane 104, and a connecting drive member is arranged between the synchronous rod 105 and the upper vane 103. When the lower vanes 104 are unfolded / closed, the upper vane 103 is synchronously unfolded / closed accordingly.
[0032] In this embodiment, the driver 106 rotates to drive the lower vane 104 connected thereto to rotate. The arrangement of the synchronous rod 105 enables all the lower vanes 104 to rotate synchronously therewith. A connecting drive member is arranged between the synchronous rod 105 and the upper vane 103, enabling the upper vane 103 to rotate synchronously with the lower vanes 104. Thus, in this application, one driver 106 can drive the upper vane 103 and the lower vanes 104 to rotate synchronously.
[0033] Further preferably, a connecting block 107 is arranged at one end of each lower vane 104. The synchronous rod 105 is rotatably connected to the connecting block 107, and the synchronous rod 105 is eccentrically arranged relative to the central axis of the connecting block 107.
[0034] Further preferably, an eccentric shaft 108 is fixedly arranged on each connecting block 107. A connecting hole 109 is arranged on the synchronous rod 105. The eccentric shaft 108 extends into the connecting hole 109 and the eccentric shaft 108 can rotate within the connecting hole 109.
[0035] In this embodiment, an eccentric shaft 108 is fixedly arranged on each connecting block 107. A plurality of connecting holes 109 are formed on the synchronous rod 105. The eccentric shaft 108 extends into the connecting hole 109 to enable the lower vane 104 to also rotate relative to the synchronous rod 105. Since the central position of the connecting block 107 is rotatably connected to the frame 100, the eccentric shaft 108 can only be eccentrically arranged relative to the connecting block 107. Then, while the lower vane 104 rotates, the synchronous rod 105 will also move up and down in the vertical direction therewith.
[0036] Further preferably, the connecting drive member includes a drive rod 110 rotatably connected to the frame 100. One end of the drive rod 110 is drivingly connected to the synchronous rod 105. A connecting rod 111 is rotatably arranged at the other end of the drive rod 110. The end of the connecting rod 111 is connected to the upper vane 103. When the drive rod 110 rotates along with the movement of the synchronous rod 105, the upper vane 103 is unfolded / closed along with the rotation of the drive rod 110.
[0037] In this embodiment, after the lower blade 104 rotates, the eccentric shaft 108 starts to rotate around the central axis of the connecting block 107, driving the synchronous rod 105 to move up and down. One end of the driving rod 110 is drivingly connected to the synchronous rod 105, so that the driving rod 110 can rotate relative to the frame 100 as the synchronous rod 105 moves up and down. Then, the connecting rod 111 fixed to the driving rod 110 can drive the upper blade 103 to open / close.
[0038] Further preferably, one end of the driving rod 110 close to the upper blade 103 is bent to form a driving portion 112. A waist-shaped groove 113 is formed in the driving portion 112. One end of the driving rod 110 is fixedly provided with a connecting portion 114. The length direction of the connecting portion 114 is perpendicular to the length direction of the driving rod 110. A slider 115 is provided on the connecting portion 114 and extends into the waist-shaped groove 113.
[0039] In this embodiment, when the synchronous rod 105 moves up and down, the synchronous rod 105 can drive the driving rod 110 to rotate upward / downward. Due to the eccentric setting between the eccentric shaft 108 and the connecting block 107, when the synchronous rod 105 moves up and down, it will also move in the front-back direction. Therefore, a waist-shaped groove 113 is provided on the driving rod 110, and the influence of the displacement of the synchronous rod 105 in the front-back direction on the driving rod 110 is offset by the sliding of the slider 115 on the connecting portion 114 in the waist-shaped groove 113.
[0040] Further preferably, a first connecting rod 116 is also hingedly provided on the frame 100. The other end of the first connecting rod 116 is hinged to a second connecting rod 117. The other end of the second connecting rod 117 is hinged to the upper blade 103. The middle of the second connecting rod 117 is rotatably connected to the middle of the connecting rod 111. The end of the connecting rod 111 is also hinged to a third connecting rod 118 which is hinged to the upper blade 103.
[0041] In this embodiment, adding the second connecting rod 117 hinged to the upper blade 103 can increase the connection with the upper blade 103 and strengthen the connection between the connecting rod 111 and the upper blade 103. The setting of multiple connecting rods makes the flipping of the blade smoother and more beautiful during the flipping process of the upper blade 103.
[0042] Further preferably, the number of the upper air inlets 101 and the lower air inlets 102 is two groups each. The two groups of upper air inlets 101 and the two groups of lower air inlets 102 are symmetrically arranged. The driver 106 is located at the middle position between the two groups of lower air inlets 102. Both ends of the driver 106 are drivingly connected to at least one lower blade 104 in the two groups of lower air inlets 102.
[0043] In this embodiment, two groups of intake grilles are symmetrically arranged on the frame 100, making the whole intake grille more aesthetically pleasing in appearance. Moreover, both ends of the driver 106 are respectively drivingly connected to at least one lower blade 104 in the two groups of lower intake grilles 102, so that one driver 106 can drive the two groups of intake grilles to open / close. It has a simple structure and good stability at the same time.
[0044] Further preferably, positioning plates 119 are symmetrically arranged on the long edges of the upper blade 103, and a step groove 120 is arranged on the frame 100. When the upper blade 103 is closed relative to the frame 100, the positioning plates 119 are embedded in the step groove 120.
[0045] In this embodiment, the arrangement of the positioning plates 119 and the step groove 120 enables the positioning plates 119 to be embedded in the step groove 120 when the upper blade 103 is closed relative to the frame 100, making the closing effect of the upper blade 103 better and more aesthetically pleasing in appearance. At the same time, the step groove 120 can also limit the rotation of the upper blade 103 to ensure the positioning angle when the upper blade 103 is closed.
[0046] Further preferably, a limiting plate 121 is fixedly arranged on the long edge of each lower blade 104, and the extending directions of the limiting plates 121 on the adjacent long edges are opposite. When the lower blade 104 is closed relative to the frame 100, the inner walls of the limiting plates 121 on the adjacent long edges abut against each other.
[0047] In this embodiment, when the lower blade 104 is closed relative to the frame 100, the inner walls of the adjacent limiting plates 121 on the adjacent lower blades 104 abut against each other, ensuring the closing effect and aesthetics between the adjacent blades, and at the same time can limit the closing angle of the lower blade 104.
