Description

Technical Field

[0001] The utility model relates to the field of vehicles, and in particular to an active air intake grille with an inward-retracting and upward-moving motion. Background Art

[0002] For traditional fuel vehicles, after the vehicle is started, the active closed air intake grille will automatically adjust the opening and closing of the blades according to the temperature of the engine, so as to achieve the effect of rapid warm-up and enable the engine to enter the best working state in the shortest time. During high-speed driving, if the air intake grille is always open, it will increase wind resistance and increase fuel consumption. If the air intake grille is closed in time, it will bring a lower drag coefficient to the vehicle, thereby improving vehicle stability and fuel economy. For new energy vehicles, the active air intake grille can increase the range by reducing the drag coefficient during high-speed driving.

[0003] Currently, most active grille blades are set in the interior space of the vehicle body, and the air intake is opened or closed by rotating around a fixed axis, thereby controlling the air intake of the air intake. However, even if the blades are switched to the open state, the blades themselves will still cover a part of the air intake area, affecting the air intake volume, and the movement trajectory is relatively single.

In addition, the terms "first", "second", etc. are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second", etc. may explicitly or implicitly include one or more features.

[0033] See also Figure 1 As shown, an embodiment of the utility model provides an active air intake grille with inward and upward movement, comprising a grille frame 1, a blade assembly 2, a drive motor 3, a connecting rod assembly and a guide assembly. The grille frame 1 is provided with an air inlet 1-1 for air flow to pass through, and the blade assembly 2 is movably mounted on the grille frame 1; the drive motor 3 is arranged on the inner side of the grille frame 1 and is connected to the blade assembly 2 through a connecting rod assembly; the connecting rod assembly is constructed to be able to drive the blade assembly 2 to move back and forth between an open position and a closed position under the drive of the drive motor 3, thereby opening or closing the air inlet 1-1 to control the air intake of the air inlet 1-1.

[0034] Specifically, Figure 2 , Figure 3As shown, the connecting rod assembly in the embodiment of the utility model includes a first driving connecting rod 4, a second driving connecting rod 5, a first transmission connecting rod 6 and a second transmission connecting rod 7. Among them, the first transmission connecting rod 6 adopts a plate-like structure whose length direction is consistent with the blade assembly 2, the upper end of the first transmission connecting rod 6 is hinged to the grid frame 1, and the lower end of the first transmission connecting rod 6 is hinged to the upper end of the blade assembly 2; the two ends of the second transmission connecting rod 7 are respectively hinged to the grid frame 1 and the lower end of the blade assembly 2.

[0035] The driving motor 3 is fixedly arranged on one side of the air inlet 1-1, one end of the first driving link 4 is drivingly connected to the output shaft of the driving motor 3, the other end of the first driving link 4 is hinged to one end of the second driving link 5, and the other end of the second driving link 5 is hinged to one side of the first transmission link 6; running the driving motor 3 can drive the first driving link 4 to rotate up and down, and the first driving link 4 drives the first transmission link 6 to rotate up and down through the second driving link 5, so that the upper end of the blade assembly 2 moves up and down along the movement trajectory of the first transmission link 6, and the lower end of the blade assembly 2 moves accordingly and drives the second transmission link 7 to rotate, so as to limit the movement trajectory of the lower end of the blade assembly 2 through the second transmission link 7 and support it.

[0036] It is understandable that the drive motor 3 can be arranged on any side of the air inlet 1-1. For example, if two air inlets 1-1 are arranged side by side on the grid frame 1 in the embodiment of the utility model, the drive motor 3 can be arranged between the two air inlets 1-1 or on the opposite sides of the two air inlets 1-1. It is only necessary to adjust the arrangement positions of the connecting rod assembly and the guide assembly accordingly. As some optional embodiments, such as Figure 1 As shown, the embodiment of the utility model is provided with a motor cover plate 8 on the inner side of the grid frame 1, and the drive motor 3 is arranged between the motor cover plate 8 and the grid frame 1. A connecting rod limiting cover plate 9 can also be installed on the motor cover plate 8, and the connecting rod limiting cover plate 9 is bent and extended to the outer side of the first driving connecting rod 4, so as to prevent the first driving connecting rod 4 from being loosened or offset when rotating.

[0037] The guide assembly is also arranged on the inner side of the grille frame 1. The guide assembly is configured to limit the movement trajectory of the blade assembly 2 so that the blade assembly 2 can reciprocate relative to the grille frame 1 along a preset trajectory, which not only ensures the stability of the movement of the blade assembly 2 and prevents the blade assembly 2 from interfering with the surrounding environment during the movement, but also makes the movement state of the blade assembly 2 more technologically beautiful. At the same time, when the blade assembly 2 moves to the open position, the blade assembly 2 can be completely hidden in the visually invisible area on the inner side of the grille frame 1 to increase the air intake area of ​​the air inlet 1-1.

[0038] Specifically, Figure 1As shown, the guide assembly in the embodiment of the utility model includes a first guide plate 10 and a guide shaft 11. The first guide plate 10 is fixedly arranged on the other side of the air inlet 1-1 (i.e., the side away from the drive motor 3). An arc-shaped guide groove 12 is opened on the first guide plate 10. One end of the guide shaft 11 is fixedly connected to the other side of the first transmission link 6 (i.e., the side away from the second drive link 5). The other end of the guide shaft 11 is slidably inserted into the arc-shaped guide groove 12. When the first transmission link 6 rotates under the drive of the drive motor 3 and the first drive link 4 and the second drive link 5, the guide shaft 11 can slide along the arc-shaped guide groove 12, thereby limiting the movement trajectory of the blade assembly 2, so that the blade assembly 2 moves back and forth relative to the grid frame 1 along a preset trajectory.

[0039] The arc guide groove 12 in the embodiment of the utility model extends upward in a direction away from the grid frame 1. When the driving motor 3 drives the first transmission connecting rod 6 to rotate upward along the arc guide groove 12, the blade assembly 2 can be retracted and moved upward to the open position. Figure 5 , Figure 6 As shown, at this time, the blade assembly 2 can be completely hidden in the visually invisible area inside the grille frame 1, thereby effectively increasing the air intake area of ​​the air intake port 1-1 and improving the cooling and ventilation effect. Conversely, when the drive motor 3 drives the first transmission connecting rod 6 to rotate downward along the arc-shaped guide groove 12, the blade assembly 2 can move outward and downward to the closed position, as shown in FIG. Figure 7 , Figure 8 As shown, at this time, the blade assembly 2 can completely close the air inlet 1-1 and keep it consistent with the exterior shape of the vehicle body, which can not only reduce wind resistance, but also make the exterior shape of the car more beautiful and ensure the overall coordination of the car.

[0040] Further, such as Figure 2 As shown, the guide assembly in the embodiment of the utility model also includes a second guide plate 13, which is fixedly arranged on the side of the drive motor 3. A guide recess 13-1 is formed on the upper edge of the second guide plate 13, and an arc-shaped protrusion 4-1 is correspondingly formed on the outer periphery of the first drive link 4. The arc-shaped protrusion 4-1 can be slidably abutted against the guide recess 13-1. When the first drive link 4 rotates under the drive of the drive motor 3, the guide recess 13-1 can support and guide the first drive link 4, thereby ensuring the stability of the movement of the connecting rod assembly.

[0041] In addition, in order to improve the stability of the blade assembly 2, the embodiment of the utility model has two second transmission connecting rods 7 relatively arranged on both sides of the blade assembly 2, one end of the two second transmission connecting rods 7 is hinged to the lower end of the blade assembly 2, and the other end is hinged to the first guide plate 10 and the second guide plate 13 respectively.

[0042] The blade assembly 2 can adopt a single-layer mode or a double-layer mode, such as Figure 4 As shown, in order to ensure the aesthetic appearance of the blade assembly 2, the blade assembly 2 in the embodiment of the utility model adopts a double-layer type, that is, the blade assembly 2 includes a blade outer plate 2-1 and a blade inner plate 2-2 arranged on the inner side of the blade outer plate 2-1, the blade outer plate 2-1 and the blade inner plate 2-2 are fastened together by screws, and the outer edges of the two can be plugged in and matched through a slot structure, and the blade outer plate 2-1 and the blade inner plate 2-2 can also be strengthened and fastened by local welding; a support foot for hinged connection with the first transmission link 6 and the second transmission link 7 can be arranged on the blade inner plate 2-2.

Ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
