Description

Technical Field

[0001] This utility model relates to the field of air intake grille technology, and in particular to an active air intake grille with a single motor and indirectly driven blades. Background Technology

[0002] In the context of increasingly fierce competition in the current automotive market, OEMs are constantly seeking effective ways to reduce component costs and enhance product competitiveness. As a crucial component of modern automotive front-end modules, the design optimization of external active grille shutters has become a key area for cost control. In traditional designs, the opening and closing of the grille blades along the Z-axis typically requires two independent actuators, controlling the movement of the left and right blades respectively. While this dual-actuator architecture ensures the synchronicity and symmetry of blade movement, it inevitably increases system complexity and manufacturing costs. With the continued pressure to reduce costs, the industry has begun exploring the feasibility of using a single-actuator drive system. Theoretically, this change can indeed achieve significant cost savings—not only reducing the procurement cost of the actuator itself but also simplifying wiring harness layout and control logic, thus reducing the overall complexity of the system. However, when this theoretical concept is implemented in specific engineering designs, it faces many serious challenges, especially given the increasingly compact layout of automotive front-end spaces.

[0003] Within the limited space of the bumper assembly, in addition to the active grille system, various electronic components are densely arranged. These functional units have strict requirements on their installation location and surrounding space, resulting in extremely limited space available for the grille drive mechanism. When using a single actuator drive scheme, the actuator can usually only be installed on one side of the grille assembly, unlike a dual-actuator scheme which allows for symmetrical left-right arrangement. Furthermore, this asymmetrical installation location directly leads to problems such as imbalance in the transmission path. The torque and motion output from the actuator need to be transmitted to the blades on both sides through mechanical components such as drive rods and linkage mechanisms. During long-distance torque transmission, problems such as transmission backlash, elastic deformation, and friction loss are inevitable. Due to the different transmission path lengths on the left and right sides, these differences in mechanical characteristics are amplified, making it difficult for the blades on both sides to maintain perfect consistency in response time, movement speed, and final position, which affects the customer's sensory experience.

[0004] Therefore, it remains crucial to provide a technical solution that uses a single actuator as the driving source and ensures consistency in the opening and closing processes of the blades on both sides. Utility Model Content
