Description

Technical Field

[0001] This utility model belongs to the field of active air intake grille technology, specifically relating to a split-blade type active air intake grille for automobiles. Background Technology

[0002] With my country's tightening of emission standards for gasoline vehicles and the government's vigorous promotion of new energy vehicles, these vehicles are gradually replacing traditional gasoline vehicles. The range anxiety of new energy vehicles has been a persistent concern for major automakers. Active grille shutters, with their advantages of low cost, reduced drag (reducing fuel and energy consumption), and significantly increased range, have been widely adopted by automakers. External active grille shutters, in particular, offer superior drag reduction compared to internal ones and are widely used in new energy vehicles. However, due to styling and airflow requirements, existing active grille shutters often present conflicting structural requirements, making a good balance impossible. Other solutions are very expensive and suffer from poor stability and noise levels. Mainstream automakers and suppliers lack effective solutions. Therefore, to address these issues, a multi-link structure is being considered, integrating two sets of blades and linkage systems with different rotation directions into a single unit. This creates a door-style air intake blade design, resolving the imbalance between airflow, styling, and structure caused by various factors. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a split-blade type active air intake grille for automobiles that is simple in structure, low in cost, and has good stability, in light of the current state of the technology.

The actuator is mounted on the frame body, the output rod is pressed against the frame body and connected to the actuator, and the output rod transmits the torque of the actuator. The drive rocker arm is connected to the output rod, the first blade connecting rod is mounted on the drive rocker arm, and the blades are mounted on the frame body. A set of blades rotating counterclockwise is connected to the first blade connecting rod through a shaft hole, and a set of blades rotating counterclockwise is connected to the second blade connecting rod through a shaft hole. The first blade connecting rod and the second blade connecting rod form a composite multi-link structure and can slide relative to each other. The actuator can transmit the output torque to each set of blades, so that each set of blades achieves the split-blade effect.

[0005] In the aforementioned type of split-blade active air intake grille for automobiles, ball joints are provided on the drive rocker, output rod, and second blade connecting rod. The drive rocker is connected to the output rod via the ball joints, and the second blade connecting rod is mounted on the drive rocker via the ball joints.

[0006] In the aforementioned type of split-blade active air intake grille for automobiles, the second blade connecting rod is provided with a sliding groove, and the first blade connecting rod is provided with a sliding shaft. The first blade connecting rod and the second blade connecting rod are connected by a sliding shaft and a sliding groove transmission pair, enabling relative sliding between the first blade connecting rod and the second blade connecting rod.

[0007] In the aforementioned type of split-blade active air intake grille for automobiles, the blades, output rods, drive rockers, first blade connecting rods, and second blade connecting rods are respectively divided into left blades, right blades, left output rods, right output rods, left drive rockers, right drive rockers, left first blade connecting rods, left second blade connecting rods, right first blade connecting rods, and right second blade connecting rods.

The actuator 200 is mounted on the frame body 100. The output rod presses against the frame body and connects to the actuator 200, transmitting torque from the actuator 200. The drive rocker is connected to the output rod. The first blade connecting rod is mounted on the drive rocker. The blades are mounted on the frame body 100. A set of counterclockwise rotating blades is connected to the first blade connecting rod via a shaft hole. A set of blades rotating counterclockwise is connected to the second blade connecting rod through a shaft hole. The first blade connecting rod and the second blade connecting rod form a composite multi-link structure and can slide relative to each other. The actuator 200 can transmit the output torque to each set of blades, so that each set of blades can achieve the effect of opening. Here, this patent mainly uses an actuator 200 to drive the motor output connecting rod assembly. The force is transferred to the composite multi-link structure through the output rod, and then the connecting rod and the blade shaft hole are connected to drive the blade. This makes the overall structure very simple, occupies very little space, has a relatively low cost, and is relatively stable.

A set of rotating blades is connected to the left second blade connecting rod 1001 and the right second blade connecting rod 1002 via shaft holes, forming an independent linkage drive system. Ball joint clips 1005 are provided on the drive rocker, output rod, and second blade connecting rod. Here, the left drive rocker 700 and right drive rocker 800 are connected to the left output rod 500 and right output rod 600 respectively via ball joint clips 1005; similarly, the left second blade connecting rod 1001 and right second blade connecting rod 1002 are mounted on the left drive rocker 700 and right drive rocker 800 respectively via ball joint clips 1005.

[0017] A set of counterclockwise rotating blades in the split-blade configuration is connected to the left first blade connecting rod 900 and the right first blade connecting rod 1000 via shaft holes, forming an independent linkage drive system. A set of clockwise rotating blades in the split-blade configuration is connected to the left second blade connecting rod 1001 and the right second blade connecting rod 1002 via shaft holes, also forming an independent linkage drive system. The second blade connecting rod has a sliding groove 1004, and the first blade connecting rod has a sliding shaft 1003. At this time, the left first blade connecting rod 900, the right first blade connecting rod 1000, the left second blade connecting rod 1001, and the right second blade connecting rod 1002 are connected to each other via the sliding shaft 1003 and the sliding groove 1004, so that the first blade connecting rod and the second blade connecting rod can slide relative to each other, connecting the two linkage drive systems together, so that the actuator 200 can transmit the output torque to each blade, so that each set of blades can achieve the split-blade effect.
