[0034] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0035] like Figure 1-5 As shown, a mechanically controlled active air intake grille comprises:
[0036] Frame 1, frame 1 is provided with a driving wheel and an air inlet 7;
[0037] The fan blade 2 is rotatably connected in the frame 1;
[0038] An elastic component 3, the elastic component 3 is used to provide a force to open the fan blade 2;
[0039] The action mechanism is arranged in the frame 1, and the air inlet 7 can drive the driving mechanism to close the fan blades 2.
[0040] Specifically, the elastic component 3 keeps the fan blades 2 in an open state for air intake, which is suitable for low-speed heat dissipation. At high speed, the wind speed is fast and the wind force is strong. The air is sucked through the air inlet 7 as power to realize the pneumatic drive mechanism to close the fan blades 2, thereby reducing wind resistance. When the vehicle speed decreases, the elastic mechanism opens the fan blades 2 for heat dissipation.
[0041] Furthermore, the air intake grille does not require electric control and automatically opens and closes according to the vehicle speed.
[0042] Furthermore, the air intake grille can also retain the original electric control through the clutch structure to adapt to use in different weather conditions or set a simple air intake control valve at the air intake hole, thereby reducing costs compared to a relatively complex control opening and closing mechanism.
[0043] In this embodiment, the elastic component 3 includes a torsion spring, and the torsion spring is arranged between the fan blade 2 and the frame 1.
[0044] Specifically, the force for keeping the fan blade 2 open is provided by a torsion spring.
[0045] In this embodiment, the action mechanism includes:
[0046] A driven wheel 4, the driven wheel 4 is coaxially arranged with the rotation axis of the fan blade 2;
[0047] A driving wheel, which is arranged in the frame 1, and a driven wheel 4 is meshed with the driving wheel;
[0048] The air from the air inlet 7 can drive the driving wheel to drive the driven wheel 4 to rotate, thereby enabling the fan blades 2 to overcome the force of the elastic component 3 to close the frame 1.
[0049] Specifically, the driving wheel is driven by wind power to drive the driven wheel 4 to rotate and close the fan blades 2.
[0050] Furthermore, the driven wheel 4 and the fan blade 2 are detachably connected via threads.
[0051] In this embodiment, the air inlet 7 is trumpet-shaped, and the driving wheel includes a coaxially arranged roller 5 and a driving wheel 6. The driving wheel 6 is meshed with the driven wheel 4. The roller 5 is radially provided with blades. The incoming wind blows the blades to drive the roller 5 to drive the driving wheel 6 to rotate.
[0052] Specifically, the trumpet shape makes it easier to collect and concentrate wind power, thereby ensuring driving force for the driving wheels.
[0053] In this embodiment, four fan blades 2 are provided, and the four fan blades 2 are distributed in a field shape, and driving wheels 6 are respectively provided on both sides of the roller 5;
[0054] A driving groove is provided at the center of the frame 1, and the driving wheel and the driven wheel 4 are arranged in the driving groove. Active grooves are respectively provided at both ends of the driving groove. Two fan blades 2 are respectively provided in each active groove. The rotating shaft of the fan blade 2 passes through the driving groove and is connected to the driven wheel 4.
[0055] Specifically, the driving wheel can drive a plurality of driven wheels 4 at the same time, and then different numbers of fan blades 2 can be arranged and used according to needs.
[0056] Furthermore, the driving wheel also includes a pin and a spline plate, and the roller 5 and the driving wheel 6 are coaxially connected through the pin and the spline plate, so that the driving wheel 6 is respectively provided on one side or both sides of the roller 5.
[0057] In this embodiment, the rotation axis of the fan blade 2 is eccentrically arranged.
[0058] Specifically, the rotation axis of the fan blade 2 is adjusted according to the layout, and the eccentric setting facilitates the adjustment of the center of gravity according to the rotation angle to balance the resistance during switching.
[0059] In this embodiment, the torsion spring is arranged between the driving slot and the fan blade 2 .
[0060] Specifically, the torsion spring is arranged close to the driven wheel 4 to prevent the fan blade 2 from twisting along the rotation axis.
[0061] In this embodiment, the air inlet 7 is arranged horizontally, above or below the axis of the displacement driving wheel.
[0062] Specifically, the horizontal setting reduces wind attenuation and avoids dead points in the same horizontal plane as the axis of the driving wheel, while the tangent direction is away from the center of the circle to ensure maximum driving force.
[0063] In this embodiment, the fan blade 2 is in a sheet shape, and the elastic component 3 is used to provide a force to make the fan blade 2 open horizontally.
[0064] Specifically, the maximum opening state of the fan is a horizontal state.
[0065] The utility model also provides a car, comprising:
[0066] The mechanically controlled active air intake grille described above.
[0067] In this embodiment, a mechanically controlled active air intake grille is used while driving as an example:
[0068] The elastic component 3 keeps the fan blade 2 in an open air intake state, which is suitable for low-speed heat dissipation;
[0069] At high speed, the wind speed is fast, and the wind is sucked in through the air inlet 7 as power, which in turn drives the driving wheel to drive the driven wheel 4 to rotate and close the fan blades 2, thereby reducing wind resistance;
[0070] When the vehicle speed decreases, the elastic mechanism opens the fan blades 2 to dissipate heat.
[0071] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
