Description

Technical Field

[0001] This utility model belongs to the field of automotive grille technology, specifically an active automotive temperature-controlled grille. Background Technology

[0002] The car grille, installed at the front of the vehicle around the headlights, is also known as the car's front fascia. It acts like the car's "respiratory organ," providing air intake and ventilation for the engine, radiator, and air conditioning system. However, under different operating conditions, it can also have some negative effects on the vehicle. For example, during high-speed driving, a large amount of airflow passes through the grille, increasing air resistance and reducing fuel economy. Furthermore, in low external temperatures, the engine requires a longer warm-up time to reach optimal operating conditions. Therefore, designing an active temperature-controlled grille that can adjust its opening or closing position according to different operating environments is one of the urgent problems to be solved. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an active temperature-controlled automotive grille to address the aforementioned deficiencies and solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: an active temperature-controlled grille for automobiles includes a frame body, an installation port opened on the front end of the frame body, a grille body disposed inside the installation port, mounting back plates disposed on both sides of the rear end of the grille body, an air inlet disposed between the two mounting back plates, guide rails symmetrically disposed at both ends of the rear end of the frame body, two sealing plates slidably disposed on the two guide rails, a first horizontal plate disposed on the mounting back plate, and a drive assembly for driving the two sealing plates to move closer or further apart, so that the air inlet is in an open or closed state. The drive assembly includes a driven wheel rotatably disposed on one side of the first horizontal plate, a drive motor disposed on the other side of the first horizontal plate, a drive wheel disposed on the drive end of the drive motor, a transmission belt disposed between the drive wheel and the driven wheel, a first connecting member disposed on one side of the upper transmission belt, and a second connecting member disposed on the other side of the lower transmission belt.

[0005] Furthermore, the sealing plate has a groove that matches the first horizontal plate. The two sides of the first horizontal plate are fixed inside the groove. The first horizontal plate is flush with the mounting back plate. The front end of the sealing plate abuts against the frame body, the mounting back plate, and the first horizontal plate. The front end of the horizontal plate and the front end of the mounting back plate abut against the rear end of the grille body.

[0006] Furthermore, a second horizontal plate is provided on the front end face of the grille body, and the two sides of the second horizontal plate are connected to the inner walls on both sides of the mounting port. The grille body has a honeycomb structure.

[0007] Furthermore, the first connector and the second connector are detachably connected to the enclosure plate via a fixing component.

[0008] Furthermore, the fixing component includes positioning posts symmetrically arranged on the first connector and the second connector, limiting blocks evenly divided into circumferences on the outer surface of the positioning posts, receiving grooves matching the first connector and the second connector, positioning grooves matching the positioning posts, and limiting grooves evenly divided into circumferences on the positioning grooves. Fastening bolts are provided on the rear end faces of the first connector and the second connector.

[0009] The beneficial effects of this utility model are:

[0010] This utility model, through the coordinated arrangement of a back plate, air intake, guide rail, first horizontal plate, drive assembly, sealing plate, driven wheel, transmission belt, first connector, second connector, and drive motor, allows the vehicle computer to drive the drive motor to operate under different working environments. The drive wheel drives the transmission belt to rotate reciprocally, causing the first and second connectors to move closer or further apart on the transmission belt. This, in turn, drives the two sealing plates and guide rails to move closer or further apart, keeping the air intake in an open or closed state. When the vehicle is traveling at high speed, the air intake is closed to reduce air resistance. In winter, closing the air intake allows the engine to quickly reach its optimal operating temperature, improving fuel economy. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Reference Figure 1-6 As shown, the active temperature-controlled grille for automobiles includes a frame body 1, an installation port 2 on the front end of the frame body, and a grille body 3 inside the installation port 2. The frame body 1 has mounting parts at both ends that are fixedly connected to the front bumper of the vehicle. The grille body 3 protects the installation port 2, preventing external objects from passing through the installation port 2 and damaging components inside the engine compartment. A second horizontal plate 12 is provided on the front end of the grille body 3, and the two sides of the second horizontal plate 12 are connected to the inner walls on both sides of the installation port 2. The grille body 3 has a honeycomb structure and a regular hexagonal structure. When impacted by external objects, the force distribution is more uniform, making it less prone to damage due to excessive force in one area. This reduces the likelihood of deformation and damage to the grille body 3 under external forces, resulting in better structural stability.

[0021] Mounting back plates 4 are provided on both sides of the rear end face of the grille body 3. The mounting back plates 4 abut against the grille body 3, increasing the structural strength and stability of the grille body 3 and making it less prone to deformation and damage due to external forces. An air intake 5 is provided between the two mounting back plates 4, through which external air enters the engine compartment. Guide rails 6 are symmetrically provided at both ends of the rear end face of the frame body 1. Two sealing plates 7 are slidably mounted on the two guide rails 6. The two sealing plates 7 are provided with guide grooves 702 that match the guide rails 6, and a drive component that drives the two sealing plates 7 to move closer or further apart, so that the air intake 5 is in an open or closed state. The guide grooves 702 and the guide rails 6 have T-shaped cross sections, which makes the movement of the sealing plates 7 more stable and less prone to detachment from the guide rails 6 due to vehicle bumps and vibrations. A first horizontal plate 8 is provided on the mounting back plate 4. The first horizontal plate 8 supports the grille body 5 at the air intake 5, further increasing the impact resistance of the grille body 8. The drive component includes a rotating component mounted on one side of the first horizontal plate 8. The system includes a driven wheel 901, a drive motor 902 on the other side of the first horizontal plate 8, a drive wheel 903 on the drive end of the drive motor 902, a transmission belt 904 between the drive wheel 903 and the driven wheel 901, a first connector 10 on one side of the upper transmission belt, and a second connector 11 on the other side of the lower transmission belt. The drive motor 902 is electrically connected to the vehicle computer. Based on vehicle sensors, the vehicle computer drives the drive motor 902 to work in different working environments. The drive motor 902 drives the drive wheel 903 to rotate, which in turn drives the driven wheel 901 and the transmission belt 904 to rotate reciprocally. Because the first connector and the second connector are arranged alternately, they move closer to or further away from each other as the transmission belt 904 rotates. This causes the two sealing plates 7 to move closer to or further away from each other, making the air intake open or closed. When the vehicle is traveling at high speed, the air intake is closed to reduce air resistance. In winter, the air intake is closed so that the engine can quickly reach its optimal operating temperature, improving fuel economy.

[0022] Preferably, the closed plate 7 has a groove 701 that matches the first horizontal plate 8. The two sides of the first horizontal plate 8 are fixed inside the groove 701. The first horizontal plate 8 is flush with the mounting back plate 4. The front end of the closed plate 7 abuts against the frame body 1, the mounting back plate 4, and the first horizontal plate 8. The front end of the first horizontal plate 8 and the front end of the mounting back plate 4 abut against the rear end of the grille body 3.

[0023] Preferably, the first connector 10 and the second connector 11 are detachably connected to the sealing plate 7 through a fixing component. The fixing component allows the sealing plate 7 to be detachably connected to the first connector 10 and the second connector 11, which facilitates later maintenance and replacement without the need for overall replacement.

[0024] Preferably, the fixing assembly includes positioning posts 1301 symmetrically arranged on the first connector 10 and the second connector 11, limiting blocks 1302 evenly divided into circumferences on the outer surface of the positioning posts 1301, receiving grooves 1303 formed on the closed plate 7 and matching the first connector 10 and the second connector 11, positioning grooves 1304 matching the positioning posts 1301 and evenly divided into circumferences on the positioning grooves 1304, and limiting grooves 1305 evenly divided into circumferences on the positioning grooves 1304. The rear end face of the second connector 11 is provided with a fastening bolt 14. The fastening bolt 14 passes through the positioning post 1301 from the rear end face of the first connector 10 and the second connector 11, and is threadedly connected to the sealing plate 7 inside the receiving groove 1303. The positioning post 1301 and the positioning groove 1303 enable the first connector 10, the second connector 11 and the sealing plate 7 to quickly form a positioning installation. The limiting block and the limiting groove cooperate to make the fit between the positioning post 1301 and the positioning groove 1303 more firm and stable, and less prone to loosening or displacement.
