DETAILED DESCRIPTION

[0057] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0058] A vehicle's active air intake grille is usually located on the front side of the vehicle (such as the front face). It is a technology used to optimize the vehicle's aerodynamic performance and improve fuel efficiency. By adjusting the opening and closing state of the air intake grille, the amount of air entering the engine compartment can be controlled; for example, when the vehicle is traveling at a low speed or the engine requires more cooling, the air intake grille will open to increase air flow into the radiator to achieve rapid cooling; when the vehicle is traveling at a high speed or the engine cooling demand is low, the air intake grille will be adjusted down or closed to reduce air resistance, thereby improving fuel economy.

[0059] In some embodiments, the vehicle's active air intake grille includes a frame, an air intake grille, a drive motor and a connecting rod. The frame has an air intake port, and the air intake grille includes multiple blades. The multiple blades are arranged in sequence along the length or width direction of the air intake port and are rotatably connected to the frame. The drive motor is connected to the multiple blades through a connecting rod. The drive motor is used to drive the blades to rotate so that the multiple blades jointly close the air intake port, or open the air intake port, that is, by rotating the blades, the area of ​​the air intake port blocked by the blades is adjusted, thereby adjusting the air intake volume of the air intake port; when the blades rotate to the minimum projected area in the air intake direction, the air intake volume of the air intake port reaches the maximum.

[0060] However, in the above embodiment, when the multiple blades in the air intake grille rotate until the air intake volume of the air intake port reaches the maximum, the blades are still in the air intake port, but the area of ​​the air intake port blocked by the blades reaches the minimum value. However, the blades still block the air intake port, thereby causing a technical problem of small air intake volume of the air intake port.

[0061] Based on the above problems, the present invention provides an active air intake grille 100 for a vehicle. Figures 1 to 9 As shown, the vehicle active air intake grille 100 includes a frame 110 and an air intake grille 120, the frame 110 has an air intake port 111, and the air intake grille 120 is movably provided on the air intake port 111 to open or close the air intake port 111; wherein, the air intake port 111 can be one or more, and when there are multiple air intake ports 111, each air intake port 111 is movably provided with an air intake grille 120 to open or close the corresponding air intake port 111 through the corresponding air intake grille 120 on each air intake port 111.

[0062] For ease of explanation, the first direction X is assumed to be the air intake direction of the air intake 111. The second direction Y is angled with the first direction X. For example, the second direction Y is perpendicular or approximately perpendicular to the first direction X. The third direction Z is angled with the second direction Y and the third direction Z. For example, the third direction Z is perpendicular or approximately perpendicular to the first direction X and the second direction Y. In some examples, the first direction X is the length of the vehicle, which may also be the direction of travel of the vehicle. The second direction Y is the width of the vehicle. The third direction Z is the height of the vehicle.

[0063] In some examples, the inner side of the air inlet 111 refers to a position projected along the first direction X and located in the projection area of ​​the air inlet 111, for example, the projection of the blade partially overlaps or completely overlaps with the projection of the air inlet 111 so as to close the air inlet 111; the outer side of the air inlet 111 refers to a position projected along the first direction X and located outside the projection area of ​​the air inlet 111, for example, the projection of the blade does not overlap with the projection of the air inlet 111 so as to open the air inlet 111.

[0064] For example, Figure 1 and Figure 7As shown in , the frame 110 includes a frame body 112, a crossbeam 113 and a longitudinal beam 116. The frame body 112 has a notch. The crossbeam 113 and the longitudinal beam 116 are both arranged in the notch and are respectively connected to the frame body 112. The crossbeam 113 extends along the second direction Y. The crossbeam 113 and the longitudinal beam 116 are intersected to isolate the notch to form two air intake groups 111a. The two air intake groups 111a are relatively arranged on opposite sides of the longitudinal beam 116, that is, one side of the longitudinal beam 116 has an air intake group 111a, and the two air intake groups 111a on both sides of the longitudinal beam 116 are relatively arranged, and each air intake group 111a includes at least two air inlets 111, for example, Figure 1 and Figure 7 In the figure, an air intake group 111a includes two air intakes 111, and the two air intakes 111 are spaced apart in the third direction Z by a cross beam 113. It can be understood that by setting multiple air intakes 111, the air intake area can be increased, thereby increasing the air intake volume to improve the heat dissipation efficiency inside the vehicle, for example, for the radiator.

[0065] Since the air intake grilles 120 provided on the air intake ports 111 are identical, the structure of the air intake grilles 120 will be described in detail below without further description of the structures of the air intake grilles 120 on the air intake ports 111 one by one.

[0066] Please continue to refer to Figures 1 to 9 As shown, the air intake grille 120 includes a first blade 121 and a second blade 122, which are movably arranged on the frame 110. The first blade 121 and the second blade 122 can move to the air inlet 111 or the outside of the air inlet 111 to close or open the air inlet 111. In this way, when the air inlet 111 needs to be closed, the first blade 121 and the second blade 122 move from the outside of the air inlet 111 to the inside of the air inlet 111. The first blade 121 and the second blade 122 are adjacently arranged and connected in the second direction Y to jointly close the air inlet 111; for example, Figure 1 In the figure, the first blade 121 and the second blade 122 are adjacently arranged and connected in the second direction Y, and the first blade 121 and the second blade 122 are flush arranged in the second direction Y, so that the first blade 121 and the second blade 122 jointly block the air inlet 111 to achieve the purpose of closing the air inlet 111.

[0067] When the air inlet 111 needs to be opened, please refer to Figures 2 to 9As shown, the first blade 121 moves relative to the second blade 122 along the first direction X to one side of the second blade 122, so that the first blade 121 and the second blade 122 are offset from each other in the first direction X, and the first blade 121 is completely located in front of or behind the second blade 122 in the first direction X. Afterwards, the first blade 121 moves relative to the second blade 122 in the second direction Y until the first blade 121 contacts the second blade 122. At this time, the first blade 121 drives the second blade 122 to continue moving until the first blade 121 drives the second blade 122 to move completely to the outside of the air inlet 111, that is, the first blade 121 and the second blade 122 are all moved out of the air inlet 111, and there will be no obstruction to the air inlet 111, so as to achieve the purpose of opening the air inlet 111, thereby increasing the air intake volume of the air inlet 111.

[0068] It can be seen that, compared with the related art in which the blades can only rotate relative to the frame 112 in the air inlet 111, so that the angles of the blades are different to adjust the air intake volume of the air inlet 111, the embodiment of the present application enables the first blade 121 and the second blade 122 to move relative to the frame 112 to move to the inside or outside of the air inlet 111, so that when the air inlet 111 is fully opened, the first blade 121 and the second blade 122 will not block the air inlet 111, and the air intake area of ​​the air inlet 111 can be further increased, thereby increasing the air intake volume and reducing wind resistance.

[0069] For example, the maximum heat dissipation area of ​​the radiator is arranged opposite to the air inlet 111. When the air inlet 111 is opened, when the first blade 121 and the second blade 122 on the air inlet 111 are moved out to the air inlet 111, the air inlet 111 is unobstructed, which increases the air intake volume of the air inlet 111, thereby improving the heat dissipation efficiency of the radiator.

[0070] Since the vehicle active air intake grille 100 provided in the embodiment of the present application can increase the air intake volume, it can match a variety of radiators with different powers. For example, under the working conditions with the same cooling requirements, the heat dissipation efficiency can be improved due to the large air intake volume. Therefore, a radiator with relatively small power can be selected, thereby reducing the vehicle's power consumption and further improving the vehicle's energy-saving and environmental protection performance. It can also meet the thermal management system of different vehicle requirements, thereby increasing the scope of application.

[0071] In order to further enhance the aesthetics of the vehicle's appearance, please continue to refer to the embodiment of this application. Figures 2 to 9As shown, when the air intake 111 needs to be opened, along the first direction X, the rear side of the second blade 122 has a movement area extending along the second direction Y, wherein the rear side of the second blade 122 is, for example, the side facing the interior of the vehicle, and the front side of the second blade 122 is, for example, the side facing the exterior of the vehicle. Therefore, by setting a movement area for the first blade 121 to move on the rear side of the second blade 122, when the air intake 111 needs to be opened, the first blade 121 moves along the first direction X to a position aligned with the movement area, and then the first blade 121 moves relative to the second blade 122 along the second direction Y within the movement area. When part of the structure of the first blade 121 contacts the second blade 122, it can drive the second blade 122 to move synchronously toward the outside of the air intake 111, thereby improving the overall appearance of the vehicle.

[0072] For example, Figure 2 As shown in the figure, when the air inlet 111 needs to be opened, the first blade 121 retreats relative to the second blade 122 in the first direction X, for example 10 mm, so that the movement areas on the first blade 121 and the second blade 122 are aligned in the first direction X. Thereafter, the first blade 121 moves relative to the second blade 122 within the movement area under the action of the driving force.

[0073] Among them, the vehicle active air intake grille 100 also includes a first driving mechanism 130 and a second driving mechanism 140. Taking the first blade 121 as an example of a driving blade, the first driving mechanism 130 and the second driving mechanism 140 are respectively connected to the first blade 121. The first driving mechanism 130 is configured to drive the first blade 121 to move in a first direction X; the second driving mechanism 140 is configured to drive the first blade 121 to move in a second direction Y, that is, the driving force for the first blade 121 to move in the first direction X comes from the first driving mechanism 130, and the driving force for the movement in the second direction Y comes from the second driving mechanism 140.

[0074] In some examples, the second drive mechanism 140 is movably connected to the frame 110 along the first direction X. When the first drive mechanism 130 drives the first blade 121 or the second blade 122 to move along the first direction X, the second drive mechanism 140 also moves relative to the frame 110 along the first direction X. In other examples, the output shaft of the second drive mechanism 140 is hingedly connected to the drive blades through a connecting rod. When the first blade 121 moves along the first direction X, the angle of the connecting rod relative to the frame 110 changes accordingly.

[0075] In some examples, the output shaft of the first drive mechanism 130 is telescopically arranged along the second direction Y, or the transmission assembly connected between the first drive mechanism 130 and the first blade 121 can be telescopically arranged along the second direction Y, so that when the first blade 121 moves along the second direction Y with the second drive mechanism 140, the first drive mechanism 130 can remain connected to the first blade 121.

[0076] In some examples, when projected along the first direction X, the projections of the first driving mechanism 130 and the second driving mechanism 140 do not overlap with the projection of the air inlet 111 .

[0077] In some examples, the first blade 121 or the second blade 122 is respectively provided with a corresponding first drive mechanism 130 and a second drive mechanism 140. In other examples, the first blade 121 or the second blade 122 shares a first drive mechanism 130, and / or the first blade 121 or the second blade 122 shares a second drive mechanism 140.

[0078] In some embodiments, please refer to Figure 10 and Figure 11 As shown, the first driving mechanism 130 includes a first driving motor 131 and a connecting rod 132 . The connecting rod 132 is connected between the first driving motor 131 and the first blade 121 , so that the first driving motor 131 drives the first blade 121 to move in the first direction X through the connecting rod 132 .

[0079] In order to improve the reliability of the movement path of the first blade 121 in the first direction X, the first blade 121 is used as an example of a driving blade in this embodiment of the application, please refer to Figures 12 to 14 、 Figure 16 and Figure 17 As shown, the connecting rod 132 has a guide rail 133, and the frame 110 has a guide groove 115 that matches the guide rail 133 and extends along the first direction X. When the first drive motor 131 drives the connecting rod 132 to drive the first blade 121 to move, the guide rail 133 moves along the extension direction of the guide groove 115 to guide the movement of the connecting rod 132 through the guide groove 115, thereby improving the accuracy and reliability of the movement route of the first blade 121 in the first direction X.

[0080] like Figure 7 and Figure 8As shown in , when there are two air intake groups 111a arranged opposite to each other, the first driving mechanism 130 is arranged on the longitudinal beam 116 and is respectively connected to the first blades 121 on each air intake 111 in the two air intake groups 111a to drive each first blade 121 to move synchronously along the first direction X, and there are two second driving mechanisms 140, and the two second driving mechanisms 140 are respectively arranged on opposite sides of the longitudinal beam 116, and one second driving mechanism 140 is connected to the first blade 121 in one air intake group 111a to drive each first blade 121 in the corresponding air intake group 111a to move synchronously along the second direction Y, thereby improving the efficiency of opening or closing the air intake 111.

[0081] In some embodiments, please refer to Figures 10 to 12 、 Figure 15 As shown, the second driving mechanism 140 includes a second driving motor 141 and a telescopic rod 142. The telescopic rod 142 is configured to extend and retract along the second direction Y, and one end of the telescopic rod 142 is connected to the first blade 121, and the other end of the telescopic rod 142 is connected to the second driving motor 141. When the second driving motor 141 drives the telescopic rod 142 to extend and retract, the telescopic rod 142 drives the first blade 121 to move along the second direction Y.

[0082] Among them, the first blade 121 and the telescopic rod 142 can be connected through a fixed bracket 143, that is, the fixed bracket 143 is fixedly connected to the first blade 121, and one end of the telescopic rod 142 is connected to the fixed bracket 143. When the telescopic rod 142 is extended or retracted, it can drive the first blade 121 to move.

[0083] When the air inlet 111 is opened, in order to make the first blade 121 move to a certain distance relative to the first blade 121, the first blade 121 drives the second blade 122 to move synchronously, the second blade 122 has a first limiting structure 1221. In this way, when the first blade 121 moves relative to the second blade 122 in the movement area until it contacts the first limiting structure 1221, the first blade 121 drives the second blade 122 to move until it moves to the outside of the air inlet 111.

[0084] For example, Figure 4 and Figure 5 As shown, the first limiting structure 1221 is arranged at the end of the second blade 122 close to one end of the edge of the frame 110. When the first blade 121 and the second blade 122 completely overlap in the first direction X, the end of the first blade 121 contacts the first limiting structure 1221, so that when the first blade 121 continues to move along the second direction Y, it can drive the second blade 122 to move synchronously until it moves to the outside of the air inlet 111 to fully open the air inlet 111.

[0085] In order to improve the movement smoothness and path accuracy of the first blade 121 in the movement area, please refer to Figure 12 As shown, the first blade 121 has a first sliding portion 1211, and a second sliding portion 1222 matching the first sliding portion 1211 is provided in the moving area. The second sliding portion 1222 extends along the second direction Y, and the first blade 121 moves along the second sliding portion 1222 through the first sliding portion 1211; exemplarily, the first sliding portion 1211 includes a sliding gear, and the second sliding portion 1222 includes a gear track, and the sliding gear is engaged with the gear track, so that when the second driving mechanism 140 drives the first blade 121 to move, the sliding gear can move along the gear track to improve the smoothness of movement and the accuracy of the route.

[0086] Please refer to Figure 18 and Figure 19 As shown, the rear side of the second blade 122 has a third sliding portion 1223 extending along the second direction Y, and the position corresponding to the third sliding portion 1223 on the frame 110 is connected to the fourth sliding portion 114. The third sliding portion 1223 is configured to be slidably connected to the fourth sliding portion 114. In this way, the smoothness and route accuracy of the movement of the second blade 122 relative to the frame 112 can be improved, and the problem of the second blade 122 getting stuck during movement can be avoided.

[0087] Exemplarily, the third sliding portion 1223 is one of the sliding rail and the sliding groove, and the fourth sliding portion 114 is the other of the sliding rail and the sliding groove; for example, the third sliding portion 1223 is the sliding rail, and the fourth sliding portion 114 is the sliding groove, and the sliding groove moves along the extension direction of the sliding rail.

[0088] In order to further improve the accuracy of the position of the second blade 122 when opening and closing the air inlet 111, the fourth sliding portion 114 has two second limiting structures 1141 arranged at intervals, and the third sliding portion 1223 is configured to slide between the two second limiting structures 1141. In this way, when the second blade 122 moves to the second limiting structure 1141 away from the side of the air inlet 111, the second blade 122 and the first blade 121 are completely located outside the air inlet 111 to fully open the air inlet 111; when the first blade 121 drives the second blade 122 to move in the opposite direction to the second limiting structure 1141 close to the side of the air inlet 111 141, the second blade 122 is blocked and limited by the second limiting structure 1141, so that the second blade 122 will not move with the movement of the first blade 121. At this time, the second blade 122 blocks part of the air inlet 111, and the first blade 121 continues to move toward the inside of the air inlet 111 relative to the second blade 122. When the first blade 121 moves out of the movement area, the first blade 121 moves forward, for example, 10 mm under the driving action of the first driving mechanism 130, so that the first blade 121 and the second blade 122 are adjacently connected and flush at the air inlet 111. At this time, the first blade 121 and the second blade 122 completely close the air inlet 111.

[0089] The process of opening and closing the air inlet 111 in the above solution is described below by way of example:

[0090] Please refer to Figures 1 to 19As shown, when the air inlet 111 is in a closed state, that is, the first blade 121 and the second blade 122 are both located at the air inlet 111 and completely block the air inlet 111, and the first blade 121 and the second blade 122 are adjacent and connected, and the outer surfaces of the first blade 121 and the second blade 122 are flush with each other, that is, the air inlet 111 is in a closed state; when the air inlet 111 needs to be opened, first, the first drive motor 131 is started, so that the first drive motor 131 drives the first blade 121 to retreat along the first direction X through the connecting rod 132, for example, retreat 10 mm, wherein the first drive motor 131 drives the first blade 121 in each air inlet 111 to move synchronously through the connecting rod 132, and when the movement area of ​​the first blade 121 and the corresponding second blade 122 rear side are in an aligned state, the second drive motor 141 is started, and the second drive motor 141 contracts along the second direction Y through the telescopic rod 142, so that the telescopic rod 142 drives the first blade 121 to move relative to the second blade 122. At this time, the second blade 122 is in a stationary state, and only the first blade 121 moves relative to the second blade 122 along the second direction Y toward the side of the second blade 122. When the first blade 121 moves to completely overlap with the second blade 122 and abuts against the first limiting structure 1221 on the second blade 122, the second drive motor 141 continues to drive the telescopic rod 142 to contract, so that the first blade 121 drives the second blade 122 to move synchronously along the second direction Y toward the outside of the air inlet 111 until the air inlet 111 is fully opened. At this time, the second blade 122 abuts against the second limiting structure 1141 on the side away from the air inlet 111 to limit the second blade 122 and prevent the second blade 122 from continuing to move.

[0091] When the air inlet 111 is in a fully open state, the second driving motor 141 drives the telescopic rod 142 to drive the first blade 121 to extend along the second direction Y. At this time, the first blade 121 drives the second blade 122 to move synchronously along the second direction Y toward the inside of the air inlet 111 until the second blade 122 moves to the second limiting structure 1141 close to the side of the air inlet 111. The second limiting structure 1141 limits the second blade 122 in the second direction Y. At this time, the second blade 122 is completely located inside the air inlet 111 and blocks part of the air inlet 111. After that, the second driving motor 141 continues to drive the telescopic rod 142 to extend along the second direction Y to drive The first blade 121 continues to move toward the direction close to the longitudinal beam 116. At this time, the second blade 122 is in a stationary state. The first blade 121 moves relative to the second blade 122 until the first blade 121 moves to a point where it does not overlap with the second blade 122 in the first direction X, that is, the first blade 121 completely moves out of the movement area. After that, the first drive motor 131 drives the first blade 121 to move forward relative to the second blade 122 through the connecting rod 132, for example, moving forward 10 mm, so that the first blade 121 is flush with the second blade 122 in the first direction X, and is adjacent to and connected to the second blade 122 in the second direction Y, so that the air inlet 111 is in a closed state.

[0092] In summary, in the vehicle active air intake grille provided in the embodiment of the present application, an air intake grille is movably arranged at the air intake, and the air intake grille includes a first blade and a second blade. The first blade and the second blade can move to the inside of the air intake or the outside of the air intake. When the first blade and the second blade both move to the inside of the air intake, and the first blade and the second blade are adjacent to each other in the second direction Y, the first blade and the second blade can jointly close the air intake; when the first blade moves relative to the second blade along the first direction X to one side of the second blade, and moves relative to the second blade along the second direction Y until it contacts the second blade, the first blade drives the second blade to move to the outside of the air intake, thereby opening the air intake. It can be seen that when the air intake is opened, the first blade and the second blade are completely located outside the air intake. Therefore, the first blade and the second blade will not block any position of the air intake. In this way, the air intake volume of the air intake can be increased, the heat dissipation effect inside the vehicle can be improved, the wind resistance can be reduced, the fuel consumption of the vehicle can be reduced, and the fuel economy can be improved.

[0093] In some embodiments of the present application, the vehicle active air intake grille 100 also includes a driving mechanism (for example, a first driving mechanism 130 and a second driving mechanism 140) and a detection mechanism (not shown in the figure). The driving mechanism is electrically connected to the detection mechanism. The detection mechanism is used to detect the operating condition information of the vehicle. Based on the operating condition information, the driving mechanism drives the first blade 121 or the second blade 122 to move relative to the frame 110, and maintains the first blade 121 and / or the second blade 122 at the target position relative to the frame 110.

[0094] In an embodiment of the present application, the detection mechanism may include a temperature sensor, a position sensor, a humidity sensor, a speed sensor, an acceleration sensor, etc., and the detection mechanism may be connected to a control terminal of the vehicle.

[0095] In an embodiment of the present application, the operating condition information of the vehicle includes at least information such as the vehicle's temperature information, driving speed or output power. For example, the operating condition information includes temperature information. When the cabin temperature is high, the driving mechanism drives the first blade 121 and the second blade 122 to move toward the outside of the air inlet 111 based on the operating condition information, thereby increasing the opening of the air inlet 111; when the cabin temperature is low, the driving mechanism drives the first blade 121 and the second blade 122 to move toward the inside of the air inlet 111 based on the operating condition information, thereby reducing the opening of the air inlet 111.

[0096] In addition, the driving mechanism can also maintain the first blade 121 and the second blade 122 at the target position relative to the frame 110 based on the operating condition information, so that the opening of the air intake 111 is adapted to the current operating condition of the vehicle. The driving mechanism can adjust the target position in time based on changes in the operating condition information to optimize the performance of the vehicle.

[0097] The technical solution of the embodiment of the present application is to set up a driving mechanism and a detection mechanism. The driving mechanism is used to drive the first blade 121 and the second blade 122 to move relative to the frame 110, and to maintain the first blade 121 and the second blade 122 at a target position relative to the frame 110, so as to meet various opening requirements of the air intake 111. The detection mechanism can detect the operating condition information of the vehicle and adjust the opening of the air intake 111 based on the operating condition information, so as to timely balance the working requirements of the vehicle and optimize the performance of the vehicle.

[0098] In some examples, the vehicle active air intake grille 100 needs to be calibrated during assembly, maintenance, or startup, which can be achieved through the following steps:

[0099] Step 1: When the air inlet 111 is completely closed by the first blade 121 and the second blade 122 , the vehicle active air intake grille 100 responds to a calibration signal to enter a calibration state.

[0100] Step 2: Control the first blade 121 and the second blade 122 to move toward the direction of opening the air inlet 111. When the first blade 121 and the second blade 122 are both blocked and unable to move, confirm that the opening of the air inlet 111 is 100%.

[0101] Step 3: Control the first blade 121 and the second blade 122 to move in the direction of closing the air inlet 111. When the first blade 121 and the second blade 122 are both blocked and cannot move, confirm that the opening of the air inlet 111 is 0%, and complete the positioning point calibration of the opening of the air inlet 111

[0102] In some examples, a calibration signal is sent by the vehicle-mounted control terminal. After the calibration is completed, the movement of the first blade 121 and the second blade 122 is controlled to adjust the opening of the air inlet 111 within the range of 0% to 100%.
