Description

Technical Field

[0001] The present application relates to the field of automobile air intake grilles, and in particular to an anti-twist active air intake grille. Background Art

[0002] The car grille, often referred to as the "front face" of a car, is not only an important part of the car's exterior design, but also plays an important functional role. It not only affects the aerodynamic performance of the car, but is also responsible for the cooling and air intake of the engine compartment.

[0003] The active air intake grille can automatically adjust the opening and closing angle according to the engine temperature without manual control. In winter, the vehicle can be warmed up faster when started, so that the engine can enter the best working state in the shortest time and the warm air can be delivered into the vehicle faster; when driving at high speed, the closed air intake grille can also bring a lower drag coefficient to the vehicle, improving vehicle stability and fuel economy.

[0004] In the related art, refer to Figure 1 The active air intake grille includes a frame 1, a connecting rod 2, an active blade 3 and a plurality of driven blades 4. Both ends of the active blade 3 and both ends of the driven blade 4 are rotatably mounted on the frame 1, and the active blade 3 and the driven blade 4 are rotatably mounted on the connecting rod 2 at the same time to form a linkage structure, so that the active blade 3 is linked with each driven blade 4. During specific operation, the driving member drives the active blade 3 to rotate, drives the connecting rod 2 to move, and then drives each driven blade 4 to rotate.

[0005] However, since the force application point of the active blade on the connecting rod is located on one side of the connecting rod, the connecting rod is subjected to uneven force during repeated movements, and the connecting rod will deviate during the movement, which increases the reaction force of the mechanism and affects the stability and service life of the overall structure. Utility Model Content

[0006] In order to make the connecting rod more evenly stressed during movement, the present application provides an anti-torsion active air intake grille, which can effectively improve the stability of the linkage structure, improve the linkage efficiency and service life, and has the advantages of simple structure and easy implementation.

[0007] The present application provides an anti-twist active air intake grille adopting the following technical solution:

[0008] A torsion-resistant active air intake grille comprises a frame, a connecting rod, an active blade, a synchronous blade and a plurality of driven blades, wherein the active blade and the driven blade are both rotatably mounted on the frame, and the active blade and the driven blade are both hinged on the connecting rod to form a linkage structure, the active blade is connected to a driving member, the synchronous blade is rotatably mounted on the frame and is coaxially connected to the active blade, and the synchronous blade is hinged on the connecting rod and is linked with the driven blade.

[0009] By adopting the above technical solution, by coaxially connecting the active blades and the synchronous blades, the two do not need to be linked by a connecting rod, thereby reducing the burden of the connecting rod transmitting from one side to the other side. The active blades and the synchronous blades drive the connecting rod to move synchronously from both sides of the connecting rod, which can ensure the force balance of the connecting rod, improve the stability of the connecting rod during movement, and thereby improve the smoothness and durability of the movement of the linkage structure of each blade.

[0010] Optionally, the ends of the rotating shaft of the active blade and the rotating shaft of the synchronous blade that are close to each other are detachably connected.

[0011] By adopting the above technical solution, the detachable connection structure is more convenient for the assembly and subsequent maintenance of the active blades and the synchronous blades.

[0012] Optionally, the rotating shaft of the active blade located on the side of the synchronous blade is formed with a plug-in portion, and the rotating shaft of the synchronous blade located on the side of the active blade is formed with a plug-in groove, the plug-in portion is plug-fitted with the plug-in groove, and the side wall of the plug-in groove forms a limiting effect on the plug-in portion along the circumferential direction of the rotating shaft of the active blade.

[0013] By adopting the above technical solution, the side wall of the plug-in slot forms a limiting effect on the plug-in part along the circumference of the active shaft, so that when the shaft of the active blade rotates, the synchronous blade can be driven to rotate through the cooperation of the plug-in part and the plug-in slot.

[0014] Optionally, the cross-section of the plug-in portion is in a "human" shape, and the plug-in groove is correspondingly opened in a corresponding shape.

[0015] By adopting the above technical solution, the torque transmission between the active blades and the driven blades is more convenient, a more efficient linkage is achieved, and the structure is stable and durable.

[0016] Optionally, a guiding slope is provided at the notch of the plug-in slot, and the guiding slope is used to guide the plug-in part to be inserted into the plug-in slot.

[0017] By adopting the above technical solution, the guiding inclined surface forms a guiding function when the plug-in part is inserted into the plug-in groove, so as to facilitate the plug-in fit between the two.

[0018] Optionally, two mounting parts are provided on the frame, and the two mounting parts are respectively located at the end of the active blade and the synchronous blade away from the connecting rod, and a plurality of mounting cavities for mounting blades are formed between the mounting parts and the frame, and the active blade, the synchronous blade and the driven blade are respectively rotatably installed in the corresponding mounting cavities at the end away from the connecting rod.

[0019] By adopting the above technical solution, multiple blades can be quickly installed using the mounting parts, which simplifies the tedious steps of installing and fixing them one by one, and effectively improves the assembly efficiency.

[0020] Optionally, the mounting member can be detachably mounted on the frame.

[0021] By adopting the above technical solution, the assembly process of each blade is optimized and the assembly efficiency is accelerated.

[0022] Optionally, the mounting member is connected to the frame body by bolts.

[0023] By adopting the above technical solution, the bolt connection is stable and easy to disassemble, which is convenient for the later inspection, disassembly and replacement of the blades.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By connecting the active blade and the synchronous blade coaxially, the two do not need to be linked by a connecting rod, which reduces the burden of the connecting rod transmitting from one side to the other. The active blade and the synchronous blade drive the connecting rod to move synchronously from both sides of the connecting rod, which can ensure the balance of force on the connecting rod and improve the stability of the connecting rod during movement, thereby improving the smoothness and durability of the movement of each blade linkage structure;

[0026] 2. By using the plug-in fit between the plug-in slot and the plug-in part, the side wall of the plug-in slot forms a limiting effect on the plug-in part along the circumference of the active shaft, so that the active blade and the synchronous blade rotate synchronously;

[0027] 3. By setting the plug-in part in a "human" shape, it is easier to transfer torque between the active blades and the driven blades, achieving more efficient linkage, and the structure is stable and durable. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is combined with Figure 1-7 This application is described in further detail.

[0037] The present application discloses an anti-twist active air intake grille. Figure 2 and Figure 3 , including a frame 1, a connecting rod 2, an active blade 3, a synchronous blade 5 and a plurality of driven blades 4, the active blade 3, the synchronous blade 5 and the driven blade 4 are all rotatably mounted on the frame 1, the active blade 3 is connected to a driving member 6, and the active blade 3 and the synchronous blade 5 are coaxially connected, the connecting rod 2 is arranged at the ends of the active blade 3 and the synchronous blade 5 close to each other, and is hingedly connected to the active blade 3 and the synchronous blade 5, and a plurality of driven blades 4 are respectively arranged on both sides of the connecting rod 2, and are hingedly connected to the connecting rod 2.

[0038] The active blade 3, the synchronous blade 5 and the multiple driven blades 4 are linked by the connecting rod 2. When the driving member 6 drives the active blade 3 to rotate, the synchronous blade 5 rotates synchronously. The two drive the connecting rod 2 to move together, so as to drive the multiple driven blades 4 to rotate synchronously, so as to achieve the synchronous rotation of all blades to adjust the air intake of the air intake grille. By connecting the active blade 3 and the synchronous blade 5 coaxially, the two do not need to be linked by the connecting rod 2, which reduces the burden of the connecting rod 2 transmitting from one side to the other side. The active blade 3 and the synchronous blade 5 drive the connecting rod 2 to move synchronously from both sides of the connecting rod 2, which can ensure the balance of force on the connecting rod 2, improve the stability of the connecting rod 2 during movement, and thus improve the smoothness and durability of the overall linkage structure.

[0039] Specifically, refer to Figure 4 , Figure 5 and Figure 6 The shaft of the active blade 3 located on one side of the synchronous blade 5 is formed with a plug-in portion 31, and the shaft of the synchronous blade 5 located on one side of the active blade 3 is provided with a plug-in slot 51, the plug-in portion 31 extends into the plug-in slot 51, and the two are plugged in and matched. The side wall of the plug-in slot 51 is used to limit the plug-in portion 31 along the circumference of the active shaft, so that when the shaft of the active blade 3 rotates, the synchronous blade 5 is driven to rotate through the cooperation of the plug-in portion 31 and the plug-in slot 51.

[0040] In this embodiment, refer to Figure 5 and Figure 6The cross section of the plug-in portion 31 is a symmetrical structure of a "human" shape, and the plug-in slot 51 is provided in a corresponding shape to cooperate with the synchronous rotation of the active blade 3 and the synchronous blade 5. In other embodiments, the plug-in portion 31 can also be set to other shapes, such as square, straight, cross, etc., as long as it can transmit torque to drive the synchronous blade 5 to rotate when the active blade 3 rotates.

[0041] Further, refer to Figure 6 A guiding slope is provided at the notch of the plug-in slot 51, and the guiding slope is used to form a guiding effect when the plug-in portion 31 is inserted into the plug-in slot 51, so as to facilitate the plug-in fit between the two.

[0042] Reference Figure 2 and Figure 7 , two mounting parts 7 are installed on the frame 1 for disassembly. The two mounting parts 7 are respectively located at the ends of the active blade 3 and the synchronous blade 5 away from the connecting rod 2. A plurality of mounting cavities 8 for mounting blades are formed between the two mounting parts 7 and the frame 1. The ends of the active blade 3, the synchronous blade 5 and the driven blade 4 away from the connecting rod 2 are respectively rotatably mounted in the corresponding mounting cavities 8. That is, the two mounting parts 7 clamp the rotating shafts of each blade away from the connecting rod 2 between the mounting parts 7 and the frame 1. When the blades rotate, the rotating shafts rotate between the mounting parts 7 and the frame 1. The mounting parts 7 can be used to quickly install multiple blades, simplify the cumbersome steps of installing and fixing one by one, and effectively improve the assembly efficiency.

[0043] Preferably, the mounting member 7 is mounted on the frame 1 by bolts, and the bolt connection is stable and easy to disassemble, which is convenient for the later inspection, disassembly and replacement of the blades.

[0045] The plug-in portion 31 cooperates with the plug-in slot 51 to transmit torque between the active blade 3 and the synchronous blade 5, thereby making the active blade 3 and the synchronous blade 5 synchronously linked, driving the connecting rod 2 to move from both sides of the connecting rod 2, improving the balance of the force on the connecting rod 2, and improving the stability and durability of the overall linkage structure.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
