[0033] Next, specific embodiments of the present utility model will be described in detail with reference to the accompanying drawings, but it is not a limitation of the present utility model.

[0034] It should be noted that the terms "first", "second", etc. in the description and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0035] This specification may use the phrase "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments", which may all refer to one or more of the same or different embodiments according to the present utility model.

[0036] Combined with Figures 1 to 3 , Figure 6 , Figure 8 And Figure 9 As shown, the XYZ coordinate axes shown in the figure are only used to refer to the relative positional relationship between relevant components, and are not a limitation on the specific layout position and direction of the components.

[0037] The utility model provides a grille blade driving assembly, which includes a driving device 1, a crank 2, a connecting rod 3, a first mounting bracket 4, and a blade 5. The driving device 1 is connected to the first end 21 of the crank 2 to drive the crank 2 to rotate. The second end 22 of the crank 2 is rotatably connected to the third end 31 of the connecting rod 3. A rocker portion 51 is provided on the blade 5. The fourth end 32 of the connecting rod 3 is rotatably connected to the fifth end 511 of the rocker portion 51. The sixth end 512 of the rocker portion 51 is rotatably connected to the first mounting bracket 4. The first mounting bracket 4 is in frictional contact with the connecting rod 3.

[0038] As shown in Figures 1 to 8 , in this embodiment, the driving device 1 is selected as a motor. The first end 21 of the crank 2 is splined to the driving device 1, so that the driving device 1 can drive the crank 2 to rotate about the connection point between the first end 21 and the driving device 1 as the central axis. The second end 22 of the crank 2 is rotatably connected to the third end 31 of the connecting rod 3. The fourth end 32 of the connecting rod 3 is rotatably connected to the fifth end 511 of the rocker portion 51. The sixth end 512 of the rocker portion 51 is rotatably connected to the first mounting bracket 4.

[0039] At the same time, as can be seen from Figure 2 , in this embodiment, the first mounting bracket 4 and the connecting rod 3 are in sliding frictional contact. The grille blade driving assembly of the utility model can be installed at the corresponding position on the vehicle. The driving device 1, the crank 2, the connecting rod 3, the rocker portion 51 and the first mounting bracket 4 form a linkage mechanism (crank-rocker mechanism). The driving device 1 drives the crank 2 to rotate, and the output of the crank-rocker mechanism is the swinging action of the rocker portion 51, so that the blade 5 swings open or closed. The user can open the blade 5 as needed to reduce the driving wind resistance and improve the vehicle's endurance.

[0040] In this embodiment, as shown in Figure 7 , a first rotating shaft 5121 is provided on the sixth end 512. A first shaft hole 43 is provided on the first mounting bracket 4. The first mounting bracket 4 is sleeved on the first rotating shaft 5121 through the first shaft hole 43. The first mounting bracket 4 can be sleeved on the first rotating shaft 5121 through the first shaft hole 43 to form a rotational connection, so that the blade 5 can rotate about the first rotating shaft 5121 as the central axis.

[0041] Similarly, as shown in Figure 4 , a third rotating shaft 221 is provided on the second end 22. A third shaft hole 311 is provided on the third end 31. The third end 31 is sleeved on the third rotating shaft 221 through the third shaft hole 311. The third end 31 is sleeved on the third rotating shaft 221 through the third shaft hole 311 to form a rotational connection, so that the connecting rod 3 and the crank 2 can rotate relative to each other about the third rotating shaft 221 as the central axis.

[0042] It should be understood that the form of rotational connection between relevant components in this embodiment can be designed as needed. For example, the above-mentioned shaft-hole fitting form, or the track fitting form (not shown in the figure), etc. The form of rotational connection is not specifically limited here, as long as relative rotation can be achieved between relevant components.

[0043] In addition, the frictional contact between the first mounting bracket 4 and the connecting rod 3 can also be rolling frictional contact. For example, a wheel set structure is provided on the connecting rod 3, which is not specifically limited here.

[0044] In the grille blade drive assembly of the present utility model, the driving device 1 is connected to the first end 21 of the crank 2, thereby driving the crank 2 to rotate. The crank 2, the connecting rod 3, the first mounting bracket 4, and the rocker portion 51 of the blade 5 together form a connecting rod mechanism, and finally the output is the swinging action of the blade 5, realizing the opening or closing of the blade 5, thereby reducing the wind resistance during vehicle driving and being beneficial to improving the vehicle's endurance. Moreover, there is frictional contact between the first mounting bracket 4 and the connecting rod 3. When the connecting rod 3 moves, it will be guided and limited by the first mounting bracket 4, to a certain extent avoiding the problems of shaking and abnormal noise between relevant components, and further improving the motion accuracy and stability of the grille blade drive assembly, ensuring that the grille functions such as reducing wind resistance and improving endurance can be realized.

[0045] Preferably, as shown in Figure 4 and Figure 5 , a hook portion 2211 and a fourth limiting protrusion 2212 are provided on the third rotating shaft 221, and the third end 31 is clamped between the hook portion 2211 and the fourth limiting protrusion 2212 through the third shaft hole 311.

[0046] The third end 31 can be sleeved through the third shaft hole 311 and pass through the hook portion 2211 until the third end 31 contacts the fourth limiting protrusion 2212, and the hook portion 2211 realizes a clamping effect on the third end 31.

[0047] In this way, it is convenient to install the crank 2 and the connecting rod 3, and at the same time, the hook portion 2211 and the fourth limiting protrusion 2212 play a certain limiting role between the crank 2 and the connecting rod 3, ensuring the stability of the rotational connection between the crank 2 and the connecting rod 3 and the motion accuracy during relative rotation.

[0048] Furthermore, the first mounting bracket 4 is rotatably connected to the first end 21.

[0049] As shown in Figure 4 , the first end 21 in this embodiment is spline-connected to the driving device 1. As shown in Figure 3As shown, the first mounting bracket 4 is rotatably connected to the first end 21 (which can be in the form of shaft - hole fit, track form, etc.). When the driving device 1 drives the crank 2 to rotate, the first end 21 is also limited and supported by the first mounting bracket 4.

[0050] In this way, by the rotatable connection between the first mounting bracket 4 and the first end 21, the crank 2 can be limited and supported by the first mounting bracket 4 at the first end 21, improving the overall reliability of the grille blade driving assembly and ensuring the stability and motion accuracy of the crank 2.

[0051] Further, a limiting post 41 is provided on the first mounting bracket 4, a limiting hole 211 is provided on the first end 21, and the crank 2 is sleeved on the limiting post 41 through the limiting hole 211.

[0052] Combined Figure 3 、 Figure 4 and Figure 6 As shown, a limiting post 41 is provided on the first mounting bracket 4. The limiting post 41 can be a complete cylindrical shape or an incomplete cylindrical shape (such as a cross - shaped post, the outermost surface of which is a part of a cylindrical surface), and can even be a conical shape, a tubular shape, etc. The shape of the limiting hole 211 on the first end 21 can be designed according to the shape of the limiting post 41, so that the first end 21 is sleeved on the limiting post 41 through the limiting hole 211. When the crank 2 rotates, the first end 21 and the limiting post 41 also rotate relative to each other.

[0053] In this way, the first mounting bracket 4 plays a role of limiting and supporting the first end 21 through the limiting post 41, ensuring the stability and motion accuracy of the crank 2.

[0054] Further, a first limiting protrusion 23 is provided on the crank 2, and the first limiting protrusion 23 extends towards the first mounting bracket 4 to be in frictional contact with the first mounting bracket 4.

[0055] Combined Figure 3 、 Figure 4 and Figure 6 As shown, a first limiting protrusion 23 is provided on the crank 2 in this embodiment. The specific shape of the first limiting protrusion 23 can be designed according to needs. In this embodiment, the first limiting protrusion 23 is strip - shaped, protruding relative to the outer surface of the crank 2 and extending towards the first mounting bracket 4, so as to be in sliding frictional contact (or rolling friction) with the outer surface of the first mounting bracket 4. In this way, through the frictional contact between the first limiting protrusion 23 and the first mounting bracket 4, a guiding and limiting effect is exerted on the crank 2, ensuring the stability and motion accuracy of the crank 2.

[0056] In another embodiment, a second limiting protrusion is provided on the first mounting frame 4, and the second limiting protrusion extends toward the crank 2 to frictionally contact the crank 2 (this solution is not shown in the figure). Similar to the first limiting protrusion 23, the second limiting protrusion can also play a guiding and limiting role for the crank 2. In addition, the first limiting protrusion 23 and the second limiting protrusion can exist at the same time, as long as there is no interference between the two within the normal range of motion.

[0057] Furthermore, a baffle portion 42 is provided on the first mounting frame 4, and the baffle portion 42 is in frictional contact with the surface of the connecting rod 3 on the side away from the blade 5.

[0058] Combination Figure 2 、 Figure 5 and Figure 6 As shown in FIG. 1 , a baffle portion 42 is provided on the first mounting frame 4. The plane where the baffle portion 42 is located is parallel to the plane where the connecting rod 3 moves (both are parallel to the ZX plane in the figure). Some reinforcing ribs can also be designed on the baffle portion 42 to increase the rigidity of the baffle portion 42. The baffle portion 42 is in sliding friction contact with the surface of the connecting rod 3 on the side away from the blade 5 (i.e., the surface of the connecting rod 3 on the positive side of the Y axis in the figure).

[0059] Thus, through the design of the baffle portion 42, the contact area between the first mounting bracket 4 and the connecting rod 3 is increased, which plays a better guiding and limiting role, and improves the stability and movement accuracy of the connecting rod 3.

[0060] Preferably, an extension plate 421 is provided at the edge of the baffle portion 42, and a limiting rib 422 is connected between the extension plate 421 and the baffle portion 42, and the limiting rib 422 is in frictional contact with the surface of the connecting rod 3 on the side away from the blade 5.

[0061] Combination Figure 2 and Figure 6 As shown in FIG. 1 , an extension plate 421 is integrally connected to the edge of the baffle portion 42. The extension plate 421 and the edge surface of the baffle portion 42 are generally at an angle of 90 degrees. A limiting rib 422 is integrally connected between the extension plate 421 and the baffle portion 42. The limiting rib 422 and the extension plate 421 form a T shape. The limiting rib 422 is in sliding frictional contact with the surface of the connecting rod 3 on the side away from the blade 5 (i.e., the surface of the connecting rod 3 on the positive side of the Y axis), thereby providing a better guiding and limiting effect on the connecting rod 3, further improving the stability and movement accuracy of the connecting rod 3.

[0062] Furthermore, the connecting rod 3 is provided with a plurality of the fourth ends 32, which are rotatably connected to the fifth ends 511 of the plurality of the rocker parts 51 in a one-to-one correspondence, and the plurality of the rocker parts 51 are fixedly connected to the plurality of the blades 5 in a one-to-one correspondence.

[0063] Combination​​​​Figure 5 As shown, there are a total of three fourth ends 32 provided on the connecting rod 3 (the number of fourth ends 32 can be designed as required), and combined with Figure 7 As shown, one rocker part 51 is integrally connected (a form of fixed connection, or other forms of fixed connection can also be used, as long as the connection between the blade 5 and the rocker part 51 is relatively fixed) to each blade 5. When all the rocker parts 51 are driven to swing, all the blades 5 can be driven to open or close. Combined with Figure 1 As shown, the three blades 5 have three rocker parts 51, that is, there are three fifth ends 511. The three fifth ends 511 are rotatably connected to the three fourth ends 32 in a one-to-one correspondence (in this embodiment, it is a form of shaft-hole fit, and other forms of rotational connection can also be used).

[0064] In this way, the grille blade drive assembly of the present utility model can drive multiple blades 5 to open or close; and when one or more blades 5 fall off or are damaged, it will not affect the movement of other blades 5, so that the grille blade drive assembly can still retain part of its performance and has better practicability.

[0065] It can be understood that in the foregoing embodiment, one side of the blade 5 (that is, Figure 1 the positive side of the Y-axis in Figure 1 ) is connected to the first mounting bracket 4 and the connecting rod 3 through the rocker part 51. The other side of the blade 5 (that is, Figure 1 the negative side of the Y-axis in

[0066] Further, a second mounting bracket 6 is further included. The second mounting bracket 6 is disposed on the side of the blade 5 away from the first mounting bracket 4 and is rotatably connected to the blade 5.

[0067] Combined with Figure 1 As shown, the second mounting bracket 6 is located on the side of the blade 5 away from the first mounting bracket 4 (that is, the side of the blade 5 facing the negative side of the Y-axis). The second mounting bracket 6 is rotatably connected to the blade 5, thereby improving the stability and movement accuracy of the blade 5, preventing the blade 5 from shaking and generating abnormal noises, and ensuring the smooth realization of the grille function.

[0068] Preferably, a second rotating shaft 52 is provided on the blade 5, a second shaft hole 61 is provided on the second mounting bracket 6, and the second mounting bracket 6 is sleeved on the second rotating shaft 52 through the second shaft hole 61; a third limiting protrusion 62 is provided on the second mounting bracket 6, and the third limiting protrusion 62 is in frictional contact with the end of the second rotating shaft 52.

[0069] Combined withFigure 1 , Figure 7 and Figure 8 As shown in Figure 1 , Figure 7 and Figure 8 , in order to facilitate the setting of the third limiting protrusion 62 and avoid increasing the occupied space of the second mounting bracket 6, a hollow cavity is provided on the second mounting bracket 6, and the third limiting protrusion 62 is arranged on the inner wall of the hollow cavity. The second shaft hole 61 communicates with the hollow cavity. After the second mounting bracket 6 is sleeved on the second rotating shaft 52 through the second shaft hole 61, the end of the second rotating shaft 52 will extend into the hollow cavity, so as to be in frictional contact with the third limiting protrusion 62. The third limiting protrusion 62 can have a certain elastic deformation, so as to generate a certain pressure on the second rotating shaft 52, playing a role in limiting the second rotating shaft 52, avoiding the shaking and abnormal noise of the blade 5, and improving the stability and movement accuracy of the blade 5.

[0070] The present utility model also provides an active air intake grille, which includes a grille outer frame 100 and the above-mentioned grille blade driving assembly, and the first mounting bracket 4 and the driving device 1 of the grille blade driving assembly are both installed on the grille outer frame 100.

[0071] Combined Figure 9 As shown in Figure 9 , the first mounting bracket 4, the driving device 1 (and the second mounting bracket 6 in the above-mentioned embodiment) are all installed on the grille outer frame 100 through fasteners (or other mounting methods). The active air intake grille is installed on a vehicle, so that the user can open the blade 5 as needed to achieve the effects of reducing wind resistance and improving endurance.

[0072] The active air intake grille in the present utility model adopts the above-mentioned grille blade driving assembly. The driving device 1 is connected to the first end 21 of the crank 2, so as to drive the crank 2 to rotate. The crank 2, the connecting rod 3, the first mounting bracket 4, and the rocker part 51 of the blade 5 together form a connecting rod mechanism, and finally the output is the swinging action of the blade 5, realizing the opening or closing of the blade 5, thereby reducing the wind resistance during vehicle driving and being beneficial to improving the endurance of the vehicle. Moreover, there is frictional contact between the first mounting bracket 4 and the connecting rod 3. When the connecting rod 3 moves, it will be guided and limited by the first mounting bracket 4, to a certain extent avoiding the problems of shaking and abnormal noise between related parts, and further improving the movement accuracy and stability of related parts (at least one of the crank 2, the connecting rod 3, and the blade 5) in the active air intake grille, ensuring that the grille functions such as reducing wind resistance and improving endurance can be realized.

[0073] The present utility model also provides a vehicle, which includes the above-mentioned active air intake grille.

[0074] The vehicle in this utility model adopts the above-mentioned active intake grille, which is connected to the first end 21 of the crank 2 through the driving device 1, thereby driving the crank 2 to rotate. The crank 2, the connecting rod 3, the first mounting bracket 4, and the rocker part 51 of the blade 5 together form a connecting rod mechanism, and finally the output is the swinging action of the blade 5, realizing the opening or closing of the blade 5, thereby reducing the wind resistance during vehicle driving and being beneficial to improving the vehicle's endurance. Moreover, there is frictional contact between the first mounting bracket 4 and the connecting rod 3. When the connecting rod 3 moves, it will be guided and limited by the first mounting bracket 4, to a certain extent avoiding the problems of shaking and abnormal noise between relevant components, and further improving the movement accuracy and stability of relevant components (at least one of the crank 2, the connecting rod 3, and the blade 5) in the active intake grille, ensuring that the grille functions such as reducing the wind resistance during vehicle driving and improving the vehicle's endurance can be achieved.

[0075] For the sake of convenience in description, spatial relative terms can be used here, such as "above...", "over...", "on the upper surface of...", "upper...", etc., to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device.
