A blade-type delayed-opening active air intake grille and vehicle

Abstract

This application provides an active air intake grille with a delayed, gradually opening blade design and a vehicle. Rotatable active blades and driven blades are installed in the air intake cavity of the grille frame. The active blades include several pairs of actively upward-opening blades and actively downward-opening blades, and the driven blades include several pairs of driven upward-opening blades and driven downward-opening blades. The actively upward-opening blades and actively downward-opening blades can rotate synchronously in opposite directions under the drive of a drive motor. After rotating a certain angle, the driven upward-opening blades and driven downward-opening blades can be driven to rotate accordingly through a delayed transmission structure. This allows the driven blades to open and close at different angles relative to the active blades at different times, achieving a gradually opening blade motion effect. This not only allows for gradual adjustment of airflow and direction to meet airflow regulation needs, but also provides diverse styling designs, enhancing the vehicle's exterior competitiveness.

Description

Technical Field

[0001] This invention relates to the field of vehicles, and more specifically to an active air intake grille with a delayed, gradually opening blade design and a vehicle thereof. Background Technology

[0002] To improve fuel economy, an increasing number of cars are adopting active grille shutters. The working principle of an active grille shutter is mainly based on comprehensive analysis of information such as engine coolant temperature, oil temperature, air conditioning system status, intake air temperature, and vehicle speed. Then, a controller sends commands to a motor to open or close the grille blades at a certain angle, thereby regulating the airflow into the engine compartment and achieving optimal cooling conditions. Simultaneously, it effectively reduces the vehicle's drag coefficient, thus reducing emissions and fuel consumption in gasoline-powered vehicles. For new energy vehicles, reducing the drag coefficient can increase the driving range.

[0003] Currently, most active air intake grille blades on the market can only open and close synchronously in the same direction, and the opening and closing angles of each set of blades are consistent. The movement mode of the blades is relatively simple. On the one hand, the ability to adjust the intake volume and airflow direction is limited, and on the other hand, it cannot meet the diverse design needs of vehicle styling.

[0004] Therefore, it is necessary to develop an active air intake grille with delayed, gradually opening blades and a vehicle to solve the aforementioned technical problems. Summary of the Invention

[0019] Optionally, the limiting structure includes a limiting sleeve and a limiting shaft. The limiting sleeve is fixedly installed to the grid frame, and the limiting shaft is fixedly connected to the active upward-turning blade and the active downward-turning blade. The limiting shaft is rotatably inserted into the corresponding limiting sleeve.

The active blades include several pairs of active upward-turning blades and active downward-turning blades, and the driven blades include several pairs of driven upward-turning blades and driven downward-turning blades. The active upward-turning blades and active downward-turning blades can rotate synchronously in opposite directions under the drive of the drive motor, and after rotating a certain angle, they can drive the driven upward-turning blades and driven downward-turning blades to rotate accordingly through a time-delay transmission structure. This allows the driven blades to open and close at different angles relative to the active blades at different times, realizing a gradual opening and closing motion effect of the blades. This can not only gradually adjust the flow rate and direction of the airflow to meet the needs of airflow regulation, but also provide diversified styling designs and enhance the vehicle's exterior competitiveness.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Furthermore, it should be understood that in the description of the present invention, the terms "upper," "lower," "left," "right," "clockwise," "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0037] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] like Figure 1 , Figure 2As shown, an embodiment of the present invention provides a blade-delayed, gradually opening active air intake grille, including a grille frame 1, grille blades, and a drive motor 2. The grille frame 1 defines multiple air intake chambers 3 arranged side-by-side along a first direction. The grille blades include active blades and driven blades, which are rotatably mounted into different air intake chambers 3 to open and close each chamber. The drive motor 2 is connected to the active blades for driving their rotation. As an optional implementation, the drive motor 2 in this embodiment is a dual-output motor. Two sets of grille blades are symmetrically arranged on the left and right sides of the drive motor 2. The output shafts at both ends of the drive motor 2 are respectively connected to the active blades of the two sets of grille blades to simultaneously drive the two sets of active blades to rotate. Due to the symmetrical design of the two sets of grille blades, the following description mainly focuses on the structure of one set of grille blades, while the other set will not be elaborated upon.

[0039] Specifically, in this embodiment, each set of active blades includes several pairs of active upward-turning blades 4 and active downward-turning blades 5 arranged in pairs along the second direction (perpendicular to the first direction). Each pair of active upward-turning blades 4 and active downward-turning blades 5 is arranged vertically opposite to each other and is connected to the output shaft of the drive motor 2 via a connecting assembly, so that the drive motor 2 can drive each pair of active upward-turning blades 4 and active downward-turning blades 5 to rotate synchronously in opposite directions through the connecting assembly. In other words, it can realize the opposing opening and closing of each pair of active upward-turning blades 4 and active downward-turning blades 5. For reference, each set of active blades in this embodiment includes three pairs of active upward-turning blades 4 and active downward-turning blades 5, wherein each pair of active upward-turning blades 4 and active downward-turning blades 5 is designed as two right-angled trapezoidal blades that are oriented in opposite directions and can be interlocked with each other.

[0040] Furthermore, such as Figure 3 As shown, the connecting components in this embodiment include a first upward-flipping link 6, a second upward-flipping link 7, a first downward-flipping link 8, and a second downward-flipping link 9. A motor mounting bracket 10 is provided on the grid frame 1, and the drive motor 2 is fixedly mounted to the motor mounting bracket 10. Two rotating rods 11 with opposite length directions are fixed to each output shaft of the drive motor 2. One end of the first upward-flipping link 6 and the first downward-flipping link 8 are respectively connected to the two rotating rods 11; the other end of the first upward-flipping link 6 is connected to the second upward-flipping link 7, which is connected to three active upward-flipping blades 4; the other end of the first downward-flipping link 8 is connected to the second downward-flipping link 9, which is connected to three active downward-flipping blades 5.

[0041] When the output shaft of the drive motor 2 rotates clockwise, the two rotating rods 11 rotate accordingly, driving the second upward-flipping rod 7 upward via the first upward-flipping connecting rod 6 and the second downward-flipping connecting rod 9 downward via the first downward-flipping connecting rod 8. This causes the three active upward-flipping blades 4 to rotate upward via the second upward-flipping connecting rod 7 and the three active downward-flipping blades 5 to rotate downward via the second downward-flipping connecting rod 9, achieving the opposing opening of the active upward-flipping blades 4 and 5. Conversely, when the output shaft of the drive motor 2 rotates counterclockwise, the second upward-flipping connecting rod 7 drives the three active upward-flipping blades 4 downward, and the second downward-flipping connecting rod 9 drives the three active downward-flipping blades 5 upward, causing the active upward-flipping blades 4 and 5 to close again. To improve the consistency and stability of the movement of the left and right sets of grille blades, as an optional implementation, this embodiment uses an integral molding method to connect the second upward-flipping connecting rods 7 of the left and right sets of active upward-flipping blades 4 into one piece, and connect the second downward-flipping connecting rods 9 of the two sets of active downward-flipping blades 5 into one piece.

[0042] Please continue reading. Figure 1 , Figure 2 As shown, the driven blades in this embodiment include several pairs of driven upward-turning blades 12 and driven downward-turning blades 13 arranged in pairs along the second direction. The number of driven upward-turning blades 12 is the same as that of the active upward-turning blades 4, and they are correspondingly arranged. The driven upward-turning blades 12 and the active upward-turning blades 4 are connected by a time-delay transmission structure. Similarly, the number of driven downward-turning blades 13 is the same as that of the active downward-turning blades 5, and they are correspondingly arranged. The driven downward-turning blades 13 and the active downward-turning blades 5 are connected by a time-delay transmission structure. When the drive motor 2 drives the active upward-turning blades 4 and the active downward-turning blades 5 to rotate, the active upward-turning blades 4 and the active downward-turning blades 5 can respectively drive the corresponding driven upward-turning blades 12 and the driven downward-turning blades 13 to rotate after rotating at a certain angle through the time-delay transmission structure. In other words, the driven upward-turning blades 12 and the driven downward-turning blades 13 can rotate after a certain period of time compared to the active upward-turning blades 4 and the active downward-turning blades 5 under the transmission action of the time-delay transmission structure, so that the active blades and the driven blades can open and close successively at different times and at different angles.

[0043] Furthermore, in this embodiment, multiple sets of driven blades are arranged side-by-side in a direction away from the active blades. Each set of driven blades has its driven upward-turning blade 12 and driven downward-turning blade 13 connected to their corresponding driven upward-turning blade 12 and driven downward-turning blade 13 via a time-delay transmission structure. This allows the driven blades to rotate sequentially in a direction away from the active blades, rotating a certain angle before driving the next set of driven blades to rotate. In other words, multiple sets of driven blades can rotate sequentially in a direction away from the active blades, lagging behind the previous set of blades for a period of time. This further achieves a gradually opening motion effect for the grille blades, which can gradually adjust the airflow and direction to meet airflow regulation needs, and also provides diverse styling designs, enhancing the vehicle's exterior competitiveness. The driven upward-turning blades 12 and driven downward-turning blades 13 in the same set can also be connected via auxiliary connecting rods 14 to improve the consistency and stability of their movement.

[0044] Specifically, such as Figure 4 , Figure 5 As shown, the time-delay transmission structure in this embodiment includes a transmission shaft sleeve 15 and a transmission shaft 16 rotatably inserted into the transmission shaft sleeve 15. The transmission shaft sleeve 15 has a transmission keyway 17 with a certain fan-shaped angle. A protruding transmission key 18 is provided on the outer periphery of the transmission shaft 16. The transmission key 18 is movably installed into the transmission keyway 17. When either the transmission shaft 16 or the transmission shaft sleeve 15 rotates, the transmission key 18 can rotate along the transmission keyway 17. After rotating a certain angle (the fan-shaped angle of the transmission keyway 17), the transmission key 18 abuts against the side wall of the transmission keyway 17, thereby driving the matching transmission shaft sleeve 15 or transmission shaft 16 to rotate. In other words, the transmission shaft 16 can rotate relative to the transmission shaft sleeve 15 within a certain angle, and transmission occurs after a certain angle of relative rotation.

[0045] As an optional implementation, in this embodiment, the left end (i.e., the end closest to the driving blade) of each driven upward-flipping blade 12 and driven downward-flipping blade 13 is fixedly connected to a drive shaft 16, and the right end is fixedly connected to a drive shaft sleeve 15. Correspondingly, the right end (i.e., the end closest to the driven blade) of the driving upward-flipping blade 4 and the driving downward-flipping blade 5 is fixedly connected to a drive shaft sleeve 15. The transmission connection between the driving blade and the driven blade can be realized simply by inserting the drive shaft 16 into the corresponding drive shaft sleeve 15. When the drive motor 2 drives the driving upward-flipping blade 4 and the driving downward-flipping blade 5 to rotate, the drive shaft sleeve 15 at the right end of the driving upward-flipping blade 4 and the driving downward-flipping blade 5 rotates accordingly. After rotating a certain angle, the side wall of the transmission keyway 17 abuts against the transmission key 18, thereby driving the matching drive shaft 16 to rotate, and then driving the driven upward-flipping blade 12 and the driven downward-flipping blade 13 to rotate, realizing the delayed transmission between the driving blade and the driven blade. Similarly, other adjacent driven blades can also achieve delayed transmission through the matching drive shaft 16 and drive shaft sleeve 15, thereby realizing the gradual opening of the grid blades.

[0046] Alternatively, as another optional implementation, a drive shaft sleeve 15 can be fixedly connected to the left end of the driven upward-turning blade 12 and the driven downward-turning blade 13, and a drive shaft 16 can be fixedly connected to the right end. Correspondingly, a matching drive shaft 16 can be fixedly connected to the right end of the active upward-turning blade 4 and the active downward-turning blade 5, and the drive shaft 16 can be inserted into the corresponding drive shaft sleeve 15. Similarly, when the drive motor 2 drives the active upward-turning blade 4 and the active downward-turning blade 5 to rotate, the drive shaft 16 at the right end of the active upward-turning blade 4 and the active downward-turning blade 5 will rotate accordingly. After rotating a certain angle, the transmission key 18 abuts against the side wall of the transmission keyway 17, thereby driving the matching drive shaft sleeve 15 to rotate, and then driving the driven upward-turning blade 12 and the driven downward-turning blade 13 to rotate, realizing the delayed transmission between the active blade and the driven blade. Understandably, in order for multiple sets of driven blades to sequentially perform delayed transmission in a direction away from the driving blades, each driven blade should be connected to a drive shaft 16 and a drive shaft sleeve 15 at both ends, so that adjacent driven blades can be connected by delayed transmission through the drive shaft 16 and the drive shaft sleeve 15 respectively. It should also be noted that when the drive shaft 16 and the drive shaft sleeve 15 are inserted and assembled, the transmission key 18 should be located at the free end of the transmission keyway 17 (the end that can move relative to the transmission keyway 17) when the driving and driven blades are in the closed state, to ensure that when the current set of blades begins to rotate, the next set of blades will begin to rotate only after a certain delay.

[0047] Understandably, as a special implementation, when the sector angle of the keyway 17 is 0°, the keyway 18 cannot move within the keyway 17; that is, the keyway 18 is directly engaged with the keyway 17. At this time, the drive shaft 16 and the drive shaft sleeve 15 cannot rotate relative to each other, and the driving blade and multiple sets of driven blades can be synchronously connected via the drive shaft 16 and the drive shaft sleeve 15. In other words, when the sector angle of the keyway 17 is 0°, the driving blade and multiple sets of driven blades can achieve synchronous opening and closing motion through the drive shaft 16 and the drive shaft sleeve 15.

[0048] Furthermore, such as Figure 7 As shown, in this embodiment, multiple open mounting slots 19 are spaced apart along the second direction on the grille frame 1 between the air intake chambers 3. After the drive shaft sleeve 15 is rotatably installed into the mounting slot 19, a removable pressure plate 20 is installed on the open side of the mounting slot 19 by bolts or other connecting parts, thereby removably restricting the drive shaft sleeve 15 within the mounting slot 19. One end of the driven blade can be directly rotatably connected to the grille frame 1 via the drive shaft sleeve 15, while the other end is rotatably connected to the grille frame 1 by inserting the drive shaft 16 into the corresponding drive shaft sleeve 15.

[0049] Furthermore, in this embodiment, the left ends of the active upward-flipping blade 4 and the active downward-flipping blade 5 are respectively rotatably connected to the grid frame 1 via a limiting structure. The limiting structure is configured to restrict the rotation angle of the active upward-flipping blade 4 and the active downward-flipping blade 5. Specifically, as shown... Figure 4 , Figure 6 As shown, the limiting structure includes a limiting sleeve 21 and a limiting shaft 22. The limiting sleeve 21 is fixedly installed to the grid frame 1, and the limiting shaft 22 is fixedly connected to the active upward-turning blade 4 and the active downward-turning blade 5. The limiting shaft 22 can be rotatably inserted into the corresponding limiting sleeve 21. A limiting keyway 23 with a certain fan-shaped angle is formed on the limiting sleeve 21. A protruding limiting key 24 is provided on the outer periphery of the limiting shaft 22. The limiting key 24 is also movably installed into the limiting keyway 23, so that the limiting shaft 22 can only rotate within a certain angle limited by the limiting keyway 23. When the drive motor 2 drives the active upward-turning blade 4 and the active downward-turning blade 5 to rotate, the limiting shaft 22 at the left end of the active upward-turning blade 4 and the active downward-turning blade 5 rotates accordingly. After rotating a certain angle (the fan-shaped angle of the limiting keyway 23), the limiting key 24 abuts against the side wall of the limiting keyway 23, making the limiting shaft 22 unable to continue rotating, thereby stopping the active upward-turning blade 4 and the active downward-turning blade 5 from rotating.

[0050] It is understandable that, in order for each group of driven blades in the grid blades to rotate smoothly, when the number of driven blades is N groups, the rotation angle of the driving blade (i.e., the sector angle of the limiting keyway 23) should be greater than N times the sector angle of the transmission keyway 17. For example, in this embodiment, each group of grid blades includes one group of driving blades and four groups of driven blades. If the sector angle of the transmission keyway 17 is 15°, then the sector angle of the limiting keyway 23 needs to be at least greater than 60° to ensure that the fourth group of driven blades, which is furthest from the driving blade, can also rotate smoothly. For reference, in this embodiment, the sector angle of the transmission keyway 17 is designed to be 15°, and the sector angle of the limiting keyway 23 is designed to be 80°. Therefore, if... Figure 8 As shown, when the active blade rotates to 80°, the four sets of driven blades can rotate sequentially (along the direction away from the active blade) by 65°, 50°, 35° and 20°, achieving the gradual opening motion effect of the grid blades.

[0051] It should be understood that the above embodiments are merely illustrative and are not intended to limit this disclosure. Based on the above embodiments, any combination of the number of drive motors 2, the number of groups of grille blades, the number of active and driven blades included in each group of grille blades, the number of upward and downward blades included in each group of active and driven blades, and their arrangement, are all within the scope of variation of this disclosure.

[0052] In addition, this embodiment of the invention also provides a vehicle equipped with the blade-delayed, gradually opening active air intake grille described in the above embodiments. Therefore, this vehicle also has the above-mentioned beneficial effects, which will not be repeated here.

Those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
