Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a double A-side blade and an air intake grille having thereon. Background Technology

[0002] The air intake grille, serving as a channel for the engine to draw air from the outside, is typically installed at the front of the vehicle body or engine compartment. Its main function is to guide outside air into the engine to cool it. An active grille can automatically adjust its opening based on engine temperature and vehicle speed, achieving intelligent control. When the vehicle is started, especially in cold winter weather when the engine temperature is low, the active grille will close to prevent cold outside air from entering the engine, allowing the interior temperature to rise rapidly and helping the engine reach its optimal operating condition as quickly as possible.

[0003] However, current air intake grille blades are generally smooth on one side and reinforced with ribs on the other side to ensure the structural strength of the blades. As a result, when the blades rotate to a certain angle, the reinforcing ribs will be exposed to the user's view, thus affecting the aesthetics of the air intake grille and reducing the user experience. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a double A-side blade and an air intake grille having the same.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A double A-side blade includes a first and second exterior blade that are covered, and a blade frame disposed between the first and second exterior blades. The exposed surfaces of the first and second exterior blades are smooth. The blade frame is provided with a plurality of reinforcing ribs, and a rotating shaft is provided on both sides of the blade frame.

[0007] Preferably, the blade skeleton is welded to the first outer blade, and the second outer blade is snapped onto the blade skeleton. Through the above improvements, the blade skeleton is welded to the first outer blade, and the second outer blade is snapped onto the blade skeleton, thus realizing the installation of the entire double A-blade and improving the convenience and reliability of assembly.

[0008] Preferably, the first outer blade is provided with a plurality of welding tabs, and the blade skeleton is formed with welding grooves for the welding tabs to be placed in. Through the above improvements, the welding tabs are placed in the welding grooves, and the blade skeleton is welded to the first outer blade using the welding tabs, thereby improving the reliability of the blade skeleton installation.

[0009] Preferably, the blade skeleton has a snap-fit ​​protrusion at its end, and the second outer blade has a snap-fit ​​groove for inserting the snap-fit ​​protrusion. Through the above improvements, in the entire assembly process, the blade skeleton is first welded to the first outer blade, and the snap-fit ​​protrusion and the snap-fit ​​groove are used for interference snap-fit, so that the second outer blade is fixed on the blade skeleton, thereby improving the reliability of the connection between the first outer blade, the second outer blade, and the blade skeleton.

[0010] Preferably, the reinforcing rib includes a vertically arranged first reinforcing protrusion and a horizontally arranged second reinforcing protrusion, and the first reinforcing protrusion and the second reinforcing protrusion are arranged alternately and connectedly. Through the above improvements, the structural strength of the blade skeleton is greatly increased, so as to ensure the structural strength and service life of the entire blade.

[0011] Preferably, a rotating protrusion is formed on the blade skeleton, and an exposed groove for the rotating protrusion to extend is formed on the second outer blade. The rotating shaft is formed on the rotating protrusion. Through the above improvements, the rotating shaft is set on the rotating protrusion, thereby improving the structural strength of the rotating shaft and preventing the rotating shaft from breaking during the rotation of the blade.

[0012] Preferably, the exposed surfaces of the first and second exterior blades are arranged in an arc shape, so that the projections of the first and second exterior blades in the length direction are elliptical. Through the above improvements, the airflow linearity of the entire blade is better and the appearance is more beautiful.

[0013] Preferably, the reinforcing rib has a welding protrusion, and the welding groove is formed on the welding protrusion. Through the above improvement, the welding groove is set on the welding protrusion, which increases the welding area of ​​the welding sheet and the blade assembly, thereby greatly increasing the welding effect of the blade frame and ensuring the reliability of the blade frame installation.

[0014] Preferably, the welding groove includes a vertically arranged first welding port, a horizontally arranged second welding port, and an interleaved and interconnected third welding port. Through the above improvements, the first welding port, the second welding port, and the third welding port are used to weld with the welding piece, which greatly improves the welding effect of the blade frame.

[0015] An air intake grille includes a frame body, on which double A-side blades are mounted. The frame body is provided with a linkage assembly for driving the double A-side blades to rotate. The frame body has a plurality of air intake slots. The double A-side blades rotate to expose or cover the air intake slots. Through the above improvements, the linkage assembly drives the double A-side blades to rotate under the action of an actuator, thereby exposing or covering the air intake slots. Furthermore, both ends of the double A-side blades are smooth, improving the aesthetics of the blades and enhancing the user experience.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0017] By setting a blade skeleton between the first and second exterior blades, and forming several reinforcing ribs on the blade skeleton, the structural strength of the entire blade is enhanced. Furthermore, the exposed surfaces of the first and second exterior blades are smooth, so that the reinforcing ribs cannot be seen during the entire rotation of the blade. Compared with traditional blades that set reinforcing ribs on the back of the blade, this not only ensures structural strength but also greatly improves the aesthetics of the blade.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0027] like Figure 1-5 As shown, a double A-side blade includes a first exterior blade 1 and a second exterior blade that are covered, and a blade frame 3 disposed between the first exterior blade 1 and the second exterior blade. The exposed surfaces of the first exterior blade 1 and the second exterior blade are smoothly disposed. The blade frame 3 is provided with a plurality of reinforcing ribs 4, and the blade frame 3 is provided with rotating shafts 5 on both sides.

[0028] By setting a blade skeleton 3 between the first and second exterior blades, and constructing several reinforcing ribs 4 on the blade skeleton 3, the structural strength of the entire blade is enhanced. Furthermore, the exposed surfaces of the first and second exterior blades are smooth, so the reinforcing ribs 4 are not visible during the blade's rotation. Compared to traditional blades that use reinforcing ribs 4 on the back of the blade, this not only ensures structural strength but also significantly improves the blade's aesthetics.

[0029] like Figure 1-5 As shown, in a further explanation of the blade assembly in this embodiment, the blade skeleton 3 is welded to the first outer blade 1, and the second outer blade is snapped onto the blade skeleton 3. In the entire blade assembly process, the blade skeleton 3 is first welded to the first outer blade 1, and the second outer blade is snapped onto the blade skeleton 3, thereby realizing the installation of the entire double A-plate blade and improving the convenience and reliability of assembly.

[0030] Specifically, the first outer blade 1 is provided with a number of welding pieces 1.1, and the blade frame 3 is formed with welding grooves 1.2 for the welding pieces 1.1 to be placed in. During the entire welding process, the welding pieces 1.1 are placed into the welding grooves 1.2, and the blade frame 3 is welded to the first outer blade 1 using the welding pieces 1.1, thereby improving the reliability of the installation of the blade frame 3.

[0031] Furthermore, a snap-fit ​​protrusion 1.3 is formed at the end of the blade frame 3, and a snap-fit ​​groove 1.4 is formed on the second outer blade for inserting the snap-fit ​​protrusion 1.3. After the blade frame 3 is welded to the first outer blade 1, the snap-fit ​​protrusion 1.3 and the snap-fit ​​groove 1.4 are used to perform an interference fit, so that the second outer blade is fixed on the blade frame 3, thereby improving the reliability of the connection between the first outer blade 1, the second outer blade, and the blade frame 3.

[0032] like Figure 1-5As shown, as a further explanation of the welding between the blade frame 3 and the first outer blade 1, a welding protrusion 2.1 is formed on the reinforcing rib 4, and a welding groove 1.2 is formed on the welding protrusion 2.1. By setting the welding groove 1.2 on the welding protrusion, the welding area of ​​the welding piece 1.1 and the blade assembly is increased, thereby greatly increasing the welding effect of the blade frame 3 and ensuring the reliability of the installation of the blade frame 3.

[0033] Specifically, the welding groove 1.2 includes a vertically arranged first welding port 2.2, a horizontally arranged second welding port 2.3, and an interleaved and interconnected third welding port 2.4. The welding blocks are matched with the dimensions of the first welding port 2.2, the second welding port 2.3, and the third welding port 2.4, and are inserted into the corresponding welding groove 1.2. The first welding port 2.2, the second welding port 2.3, and the third welding port 2.4 are used to weld with the welding piece 1.1, which greatly improves the welding effect of the blade frame 3.

[0034] like Figure 1-5 As shown, as a further explanation of the reinforcing rib 4 on the blade frame 3, the blade frame 3 includes a main body and rotating shafts disposed on both sides of the main body. The reinforcing rib 4 is formed on the main body. The reinforcing rib 4 includes a vertically arranged first reinforcing protrusion 1.5 and a horizontally arranged second reinforcing protrusion 1.6. The first reinforcing protrusion 1.5 and the second reinforcing protrusion 1.6 are staggered and connected. Through the cooperation of the first reinforcing protrusion 1.5 and the second reinforcing protrusion 1.6, the structural strength of the blade frame 3 is greatly increased to ensure the structural strength and service life of the entire blade.

[0035] Preferably, the blade frame 3 has a rotating protrusion 1.7, the second outer blade has an exposed groove for the rotating protrusion 1.7 to extend out, and the rotating shaft 5 is formed on the rotating protrusion 1.7. By setting the rotating shaft 5 on the rotating protrusion 1.7, the structural strength of the rotating shaft 5 is improved, and the rotating shaft 5 is prevented from breaking during the rotation of the blade.

[0036] Preferably, the exposed surfaces of the first and second exterior blades are arranged in an arc shape, so that the projections of the first and second exterior blades in the length direction are elliptical, which makes the airflow of the entire blade more linear and the appearance more beautiful.

[0037] like Figure 6 As shown, regarding a further explanation of the implementation of the air intake grille using the double A-side blades in this embodiment, the air intake grille includes a frame body 3.1, the double A-side blades are mounted on the frame body 3.1, and the frame body 3.1 is provided with a connecting rod assembly 3.2 for driving the double A-side blades to rotate. The frame body 3.1 is provided with a plurality of air intake slots 3.3, and the double A-side blades rotate to expose or cover the air intake slots 3.3.

[0038] During use, the linkage assembly 3.2 drives the double A-side blades to rotate under the action of the actuator, thereby exposing or covering the air inlet slot 3.3. Both ends of the double A-side blades are smooth, which improves the aesthetics of the blades and enhances the user experience.

[0039] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
