Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an active air intake grille that opens at multiple angles in the same direction. Background Technology

[0002] An active grille shutter is an intelligent automotive component that automatically adjusts the opening and closing angle of the grille blades through a motor or electronic control system to adapt to different operating conditions. Its core functions include dynamically reducing wind resistance (improving fuel economy), precisely regulating engine / battery temperature (optimizing thermal management), improving high-speed aerodynamic stability, and helping to reduce cold start emissions. It also takes into account radiator protection and NVH optimization, making it one of the key technologies for balancing energy saving and performance in modern automobiles.

[0003] For example, a longitudinally arranged active air intake grille disclosed in CN222310377U includes a grille frame and a plurality of arranged blades. The blades have a connecting side and a movable side arranged opposite to each other along their length direction. The connecting side is rotatably connected to the grille frame, and the movable side can rotate about the axis of the connecting side under the action of a drive component. It also includes a guide bracket, which is provided with a guide part that can be connected to the movable side and guide and limit it.

[0004] However, in the aforementioned existing technology, the multi-blade motion mechanism active air intake grille has a uniform blade angle when the blades are in the closed state. Existing automotive exterior environmental components often require some tilt angles to improve aesthetics, which makes it impossible for conventional active air intake grilles to match them. They can only adapt to the active air intake grille by changing the environmental components, resulting in failure to meet the overall vehicle appearance requirements. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model proposes an active air intake grille that opens at multiple angles in the same direction.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] An active air intake grille that opens at multiple angles in the same direction includes a frame body, on which a blade group is rotated, the blade group including a first blade, a second blade, and a third blade, and the frame body is provided with a drive linkage assembly for driving the blade group to swing.

[0008] The drive linkage assembly includes a synchronous connecting rod connecting the first blade and the second blade, a driven connecting rod connecting the third blade, a connecting rod connecting the synchronous connecting rod and the driven connecting rod, and a drive unit for driving the connecting rod to rotate. The active air intake grille includes at least an open state and a closed state. When the active air intake grille is in the open state, the blade group has the same opening angle and is arranged relatively parallel. When the active air intake grille is in the closed state, the first blade and the second blade are arranged horizontally, and the third blade is arranged at an angle and forms a set angle with the second blade.

[0009] Preferably, the blade assembly has a main rotating shaft and an auxiliary shaft, and the main rotating shaft is connected to the frame body. The auxiliary shafts of the first and second blades are connected to a synchronous connecting rod, and the auxiliary shaft of the third blade is connected to a driven connecting rod. With the above improvements, when the drive unit drives the connecting rod to rotate, the connecting rod synchronously drives the synchronous connecting rod and the driven connecting rod to rotate. The main rotating shafts of the first, second, and third blades are connected to the frame body, the auxiliary shafts of the first and second blades are connected to the synchronous connecting rod, and the auxiliary shaft of the third blade is connected to the driven connecting rod, thereby realizing the synchronous rotation of the blade assembly.

[0010] Preferably, the angle A formed by the extension line of the center of the synchronous connecting rod and the connecting line between the centers of the main rotating shaft and the auxiliary shaft on the second blade is always greater than 30 degrees during the movement. Similarly, the angle B formed by the extension line of the center of the driven connecting rod and the connecting line between the centers of the main rotating shaft and the auxiliary shaft on the third blade is always greater than 30 degrees during the movement. Through these improvements, angle A and angle B are always greater than 30 degrees throughout the entire movement, thus making the motor torque more efficient.

[0011] Preferably, when the active air intake grille is in the open state, the first blade and the second blade rotate at a first angle, and the third blade rotates at a second angle, so that the first blade, the second blade, and the third blade are arranged relatively parallel. Through the above improvements, it is better adapted to the environmental components.

[0012] Preferably, the connecting rod has a first connecting part that connects the synchronous connecting rod and the driven connecting rod, and a second connecting part that connects to the drive unit. The center distance between the first connecting part and the second connecting part is the same as the center distance between the main rotating shaft and the auxiliary shaft. Through the above improvements, the movement of the first blade, the second blade and the connecting rod are completely synchronized. This not only ensures that the rotation angle of the two blades is always the same, ensuring that the mechanism operates smoothly without misalignment or jamming, but also that when the drive unit drives the connecting rod, the two blades are subjected to uniform force, reducing vibration and wear.

[0013] Preferably, the blade assembly is connected to a drive linkage assembly on one side and an auxiliary linkage assembly on the other side. The auxiliary linkage assembly includes an auxiliary synchronizing rod and an auxiliary connecting rod connected to the auxiliary synchronizing rod. The auxiliary connecting rod is connected to the third blade, and the auxiliary synchronizing rod is connected to the first blade and the second blade. Through the above improvements, the stability of the blade assembly during operation is further enhanced.

[0014] Preferably, when the active air intake grille is closed, the blade assembly abuts against each other, and abutting protrusions are formed on the blade assembly. Through the above improvements, when the active air intake grille is closed, the abutting protrusions on the first blade, the second blade, and the third blade abut against each other, further improving the stability and reliability of the blade assembly in the closed state.

[0015] Preferably, a blocking protrusion is formed on the frame body. When the active air intake grille is closed, the blocking protrusion abuts against the third blade to restrict the third blade from continuing to rotate. Through the above improvements, the rotation stroke of the third blade is limited, and the third blade is kept at a specified angle, thereby better cooperating with the surrounding environment.

[0016] Preferably, the frame body is provided with a limiting bracket, and the limiting bracket is formed with multiple limiting protrusions. The limiting protrusions are arranged on the rotation path of the blade assembly. Through the above improvement, the limiting protrusions on the limiting bracket are used to limit the rotation stroke of the blade assembly, so that the blade assembly rotates within a limited angle.

[0017] Preferably, the frame body has a pressure block, and the frame body has a rotating groove for the main rotating shaft to be inserted. The pressure block is pressed on the rotating groove to prevent the main rotating shaft from detaching from the frame body. Through the above improvements, the stability and reliability of the fit between the blade assembly and the frame body are ensured.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] By setting a blade group on the main body and a drive linkage assembly that drives the blade group to swing synchronously, the blade group includes a first blade, a second blade, and a third blade. The drive linkage assembly includes a synchronous connecting rod connecting the first blade and the second blade, a driven connecting rod connecting the third blade, a connecting rod connecting the synchronous connecting rod and the driven connecting rod, and a drive unit that drives the connecting rod to rotate. When the active air intake grille is in the open state, the blade group has the same opening angle and is arranged relatively parallel. When the active air intake grille is in the closed state, the first blade and the second blade are arranged horizontally, and the third blade is arranged at an angle and forms a set angle with the second blade to better match the surrounding environmental components and meet the overall vehicle appearance requirements.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0030] like Figure 1-7As shown, an active air intake grille that opens at multiple angles in the same direction includes a frame body 1, on which a blade group 2 is mounted. The blade group 2 includes a first blade 1.1, a second blade 1.2, and a third blade 1.3. A drive linkage assembly 3 for driving the blade group 2 to swing is provided on the frame body 1.

[0031] Specifically, the drive linkage assembly 3 includes a synchronous connecting rod 2.1 connecting the first blade 1.1 and the second blade 1.2, a driven connecting rod 2.2 connecting the third blade 1.3, a connecting rod 2.3 connecting the synchronous connecting rod 2.1 and the driven connecting rod 2.2, and a drive unit 2.4 driving the connecting rod 2.3 to rotate. The active air intake grille includes at least an open state and a closed state. When the active air intake grille is in the open state, the blade group 2 has the same opening angle and is arranged relatively parallel. When the active air intake grille is in the closed state, the first blade 1.1 and the second blade 1.2 are arranged horizontally, and the third blade 1.3 is arranged obliquely and forms a set angle with the second blade 1.2.

[0032] Furthermore, when the active air intake grille is in the open state, the first blade 1.1 and the second blade 1.2 rotate at a first angle, and the third blade 1.3 rotates at a second angle, so that the first blade 1.1, the second blade 1.2, and the third blade 1.3 are arranged relatively parallel. This allows the active air intake grille to be set at a specified tilt angle in the closed state to match the surrounding environmental components, meet the overall vehicle appearance requirements, and significantly improve the appearance of the active air intake grille. At the same time, in the open state, the blade group 2 is relatively parallel to meet the air intake effect.

[0033] like Figures 4 to 7 As shown, as a further explanation of the cooperation between the blade group 2 and the drive linkage assembly 3, the blade group 2 is equipped with a main rotating shaft 3.1 and an auxiliary shaft 3.2. The main rotating shaft 3.1 is connected to the frame body 1. The auxiliary shafts 3.2 of the first blade 1.1 and the second blade 1.2 are connected to the synchronous connecting rod 2.1, and the auxiliary shaft 3.2 of the third blade 1.3 is connected to the driven connecting rod 2.2.

[0034] When the drive unit 2.4 drives the connecting rod 2.3 to rotate, the connecting rod 2.3 synchronously drives the synchronous connecting rod 2.1 and the driven connecting rod 2.2 to rotate. The main rotating shaft 3.1 of the first blade 1.1, the second blade 1.2, and the third blade 1.3 is connected to the frame body 1. Since the auxiliary shaft 3.2 of the first blade 1.1 and the second blade 1.2 is connected to the synchronous connecting rod 2.1, and the auxiliary shaft 3.2 of the third blade 1.3 is connected to the driven connecting rod 2.2, the first blade 1.1, the second blade 1.2, and the third blade 1.3 rotate synchronously as the connecting rod 2.3 rotates.

[0035] Specifically, the angle A formed by the center extension line of the synchronous connecting rod 2.1 and the center connecting line of the main rotating shaft 3.1 and auxiliary shaft 3.2 on the second blade 1.2 is always greater than 30 degrees during the movement. The angle B formed by the center extension line of the driven connecting rod 2.2 and the center connecting line of the main rotating shaft 3.1 and auxiliary shaft 3.2 on the third blade 1.3 is always greater than 30 degrees during the movement. Both angles A and B are always greater than 30 degrees during the entire movement, thus making the motor torque more labor-saving.

[0036] The larger the included angle (e.g., always greater than 30°), the higher the proportion of the tangential component, the higher the force utilization rate, and the less effort the motor needs. If the included angle is too small (e.g., close to 0°), the tangential component approaches zero, and at this time, a very large torque is required to drive the blade (similar to a "locked" state). Keeping the included angle >30° can avoid approaching the dead point, ensure smooth movement, maximize the tangential component force and minimize the useless radial component force, thereby reducing the motor load and achieving the purpose of saving effort.

[0037] In addition, the connecting rod 2.3 has a first connecting part 3.3 that connects the synchronous connecting rod 2.1 and the driven connecting rod 2.2, and a second connecting part 3.4 that connects to the drive unit 2.4. The center distance between the first connecting part 3.3 and the second connecting part 3.4 is the same as the center distance between the main rotating shaft 3.1 and the auxiliary shaft 3.2, so that the movement of the first blade 1.1, the second blade 1.2 and the connecting rod 2.3 is completely synchronized. This not only ensures that the rotation angle of the two blades is always the same, ensuring that the mechanism runs smoothly without misalignment or jamming, but also that when the drive unit 2.4 drives the connecting rod 2.3, the two blades are subjected to uniform force, reducing vibration and wear.

[0038] like Figure 5 As shown, in some other embodiments, the blade group 2 is connected to the drive linkage assembly 3 on one side and to the auxiliary linkage group 4.1 on the other side. The auxiliary linkage group 4.1 includes an auxiliary synchronizing rod 4.2 and an auxiliary connecting rod 4.3 connected to the auxiliary synchronizing rod 4.2. The auxiliary connecting rod 4.3 is connected to the third blade 1.3, and the auxiliary synchronizing rod 4.2 is connected to the first blade 1.1 and the second blade 1.2. The auxiliary linkage group 4.1 limits the other side of the blade group 2, thereby further improving the stability of the blade group 2 during operation.

[0039] like Figures 1 to 3 As shown, as a further explanation of the cooperation between the frame body 1 and the blade group 2, when the active air intake grille is closed, the blade group 2 abuts against each other, and the blade group 2 has abutting protrusions 5.1. When the active air intake grille is closed, the abutting protrusions 5.1 on the first blade 1.1, the second blade 1.2, and the third blade 1.3 abut against each other, further improving the stability and reliability of the blade group 2 in the closed state.

[0040] Furthermore, a blocking protrusion 5.2 is formed on the frame body 1. When the active air intake grille is closed, the blocking protrusion 5.2 abuts against the third blade 1.3 to restrict the third blade 1.3 from continuing to rotate, limit the rotation stroke of the third blade 1.3, and keep the third blade 1.3 at a specified angle, so as to better cooperate with the surrounding environment.

[0041] Preferably, the frame body 1 is provided with a limiting bracket 5.3, and the limiting bracket 5.3 is formed with multiple limiting protrusions 5.4. The limiting protrusions 5.4 are arranged on the rotation path of the blade group 2. The limiting protrusions on the limiting bracket 5.3 are used to limit the rotation stroke of the blade group 2, so that the blade group 2 rotates within a limited angle.

[0042] Preferably, the frame body 1 has a pressure block 6.1, and the frame body 1 has a rotating groove 6.2 for the main rotating shaft 3.1 to be inserted into. The pressure block 6.1 is pressed on the rotating groove 6.2 to restrict the main rotating shaft 3.1 from detaching from the frame body 1, so as to ensure the stability and reliability of the fit between the blade assembly 2 and the frame body 1.

[0043] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
