Description

Technical Field

[0001] This utility model belongs to the field of automotive air intake grille structure design technology, specifically relating to a blade-adjustable air intake grille assembly. Background Technology

[0002] As a key component of the front of a car, the air intake grille not only affects the vehicle's appearance but also plays a crucial role in its performance. The design of the air intake grille must ensure that sufficient air can enter the engine compartment. During vehicle operation, air is introduced into the engine compartment to cool it down and provide sufficient oxygen for the combustion of fuel, ensuring complete combustion. The design of the air intake grille has a direct impact on vehicle performance.

[0003] In actual vehicle operation, engine conditions are complex and varied. Different driving speeds, ambient temperatures, and load conditions all have different requirements for air intake. When starting a vehicle in cold weather, the engine needs to warm up as quickly as possible to reach its optimal operating temperature. At this time, a smaller air intake helps to preheat the engine quickly. However, when driving at high speeds or when the engine is under high load, a large amount of cold air is needed to enhance heat dissipation and ensure stable engine operation. However, traditional active air intake grilles with a fixed opening degree cannot be adjusted in real time and flexibly according to these actual operating conditions. This makes it difficult for the engine to obtain the optimal air intake under different operating conditions, resulting in problems such as incomplete combustion and unstable power output. This seriously affects the normal performance of the engine and reduces the vehicle's power performance and fuel economy. Utility Model Content

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] Please see Figures 1 to 4 As shown, this utility model embodiment provides a blade-adjustable air intake grille assembly, mainly composed of a mounting frame 1, a movable slot 2, blades 3, auxiliary components 4, mounting slot 5, and adjustment components 6. The mounting frame 1, serving as the basic support structure of the entire assembly, is made of high-strength aluminum alloy. This material is not only lightweight, effectively reducing the overall weight of the vehicle and lowering fuel consumption, but also possesses excellent corrosion resistance and strength, ensuring long-term stable operation under various complex automotive driving environments. Its shape design perfectly matches the front of the car, ensuring structural stability while also considering the aesthetics and harmony of the vehicle's appearance. The movable slot 2, located inside the mounting frame 1, is elongated and provides space for the rotation of the blades 3. Inside the movable slot 2, three blades 3 are evenly distributed at equal intervals. The blades 3 are made of lightweight, high-strength carbon fiber composite material. This material has an excellent strength-to-weight ratio, ensuring that the blades 3 can withstand a certain amount of air pressure while significantly reducing their own weight, thus improving the sensitivity of adjustment.

[0023] Please see Figures 1 to 4As shown, the movable slot 2 is also equipped with two sets of auxiliary components 4, which play a key role in improving the adjustment performance of the blade 3. The auxiliary components 4 specifically include a connecting plate 401 and an elastic element 402 fixedly connected to the outer surface of the connecting rod 607. The connecting plate 401 is made of stainless steel, possessing good toughness and fatigue resistance, and can stably transmit force. It is flat and tightly welded to the outer surface of the connecting rod 607. The elastic element 402 is fixedly connected to the outer surface. During adjustment, the rotation of the connecting rod 607 is transmitted to the elastic element 402. The elastic element 402 is a torsion spring connected to the inner wall of the movable slot 2. When the blade 3 is adjusted, the elastic element 402 stores and releases energy through its own elastic deformation, providing a counterforce to the adjustment component 6 and the blade 3, ensuring tight meshing between the transmission components, avoiding tooth jamming, and improving the stability and accuracy of the adjustment process. A set of mounting slots 5 is opened inside the mounting frame 1 for installing the adjustment component 6. The mounting slots 5 have high dimensional accuracy and fit tightly with the various parts of the adjustment component 6, ensuring that the adjustment component 6 is securely installed and reliably operated.

[0024] Please see Figures 1 to 4 As shown, the adjustment assembly 6 is the core component for adjusting the opening angle of the blade 3, including an electric actuator 601, a toothed plate 602, a gear 603, an electric actuator 604, a toothed plate 605, a gear 606, and a connecting rod 607. Electric actuators 601 and 604 are fixedly installed on the inner walls of the left and right mounting slots 5, respectively. They are high-precision DC electric actuators, characterized by fast response and stable thrust. The output end of electric actuator 601 is fixedly connected to toothed plate 602, and the output end of electric actuator 604 is fixedly connected to toothed plate 605. Both toothed plates 602 and 605 are rectangular strips made of high-quality steel, with a hardened surface, high hardness, and good wear resistance. Their outer surfaces are slidably connected to the inner wall of the mounting slots 5, allowing them to slide smoothly up and down under the push of the electric actuators.

[0025] Please see Figures 1 to 4As shown, the outer surface of tooth plate 602 meshes with three equally spaced gears 603, and the outer surface of tooth plate 605 meshes with three equally spaced gears 606. Gears 603 and 606 are both located inside the mounting groove 5. They are made of high-strength alloy steel, and after precision machining and heat treatment, they have high tooth surface precision and smooth transmission. A connecting rod 607 is fixedly connected to the outer surface of gear 603. The connecting rod 607 is a solid metal rod made of aluminum alloy, which is lightweight and high-strength. One end of the connecting rod 607 is welded to gear 603, and the other end is welded to gear 606. At the same time, its outer surface is fixedly connected to the inner wall of blade 3. When gear 603 and gear 606 rotate, the connecting rod 607 rotates accordingly, thereby driving blade 3 to rotate around its axis in the movable groove 2, realizing the adjustment of the opening angle of blade 3, and precisely controlling the amount of air entering the engine compartment. The outer surface of gear 603 and the inner wall of the mounting frame 1 are rotatably connected by a high-precision bearing, which reduces rotational friction, improves transmission efficiency, and ensures the smoothness of the entire adjustment process.

[0026] In this embodiment, through the close cooperation between the mounting frame 1, the movable slot 2, the blade 3, the auxiliary component 4, the mounting slot 5, and the adjustment component 6, the blade-adjustable air intake grille assembly can stably and efficiently adjust the air intake volume according to the needs of different engine operating conditions, optimize the engine's working efficiency, reduce vehicle wind resistance, and improve the vehicle's fuel economy. This effectively solves the problem that traditional air intake grilles cannot flexibly adjust the air intake volume, thereby improving the overall performance of the vehicle.

[0027] When this utility model is in use, and the vehicle's driving conditions change, requiring adjustment of the air intake grille's opening angle, the adjustment component 6 starts working. Electric push rod 601 is activated, its output end pushing toothed plate 602 to slide up and down within the left mounting slot 5. The outer surface of toothed plate 602 meshes with three equally spaced gears 603, causing them to rotate. Simultaneously, electric push rod 604 is activated synchronously with electric push rod 601, its output end pushing toothed plate 605 to slide up and down within the right mounting slot 5. This causes toothed plate 605 to drive the three meshing gears 606 to rotate. During the simultaneous rotation of gears 603 and 606, connecting rod 607 rotates. Connecting rod 607 then drives blades 3 to rotate, causing blades 3 to rotate within the movable slot 2 around connecting rod 607, thus adjusting the opening angle of blades 3 to control the amount of air entering the engine compartment. Simultaneously, the rotation of connecting rod 607 also drives... The connecting plate 401, which is fixedly connected to its outer surface, rotates with it. At this time, the connecting plate 401 applies torque to the elastic element 402, causing the elastic element 402 to deform and store a certain amount of elastic potential energy. When the electric push rod 601 and the electric push rod 604 drive the toothed plate 602 and the toothed plate 605 to move up and down, the deformed elastic element 402 releases its elastic potential energy, which can then apply a reverse rotational force to the connecting plate 401. At this time, the connecting plate 401 can apply a reverse rotational force to the connecting rod 607, the gear 606, and the blade 3, so that the gear 603 is always meshed with the toothed plate 602. Similarly, the gear 606 is always meshed with the toothed plate 605, so that the transmission components always maintain the best meshing state, avoiding the occurrence of tooth jamming, and making the adjustment process more stable. Through the cooperation between the adjustment component 6, the auxiliary component 4, and the blade 3, the entire air intake grille assembly can adapt to different engine operating conditions and improve vehicle performance.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
