Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an anti-swing mechanism and an active air intake grille with the mechanism. Background Art

[0002] In the automotive industry, active grilles are an important energy-saving component that can effectively reduce wind resistance during vehicle driving, improve fuel economy or extend battery life by intelligently adjusting the opening and closing of the grilles. The design of active grilles usually includes a main frame with multiple movable blades mounted on it. These blades are opened and closed synchronously through a mechanical transmission device (such as a motor-driven connecting rod mechanism).

[0003] Since the driving rod in the mechanical transmission device has a long force arm, it is easy to shake during the rotation process, causing the blades to open and close unsmoothly, producing abnormal noises, and accompanied by a greater risk of parts damage. In actual applications, the vehicle may encounter various complex road conditions and dynamic loads during driving, such as bumps, sudden acceleration, and sudden deceleration. These dynamic factors may also cause the driving rod to swing or vibrate unnecessary. This swing will not only affect the synchronization and accuracy of the blades, but may also cause increased mechanical wear, shorten the service life of components, and even affect the performance and safety of the entire vehicle.

[0004] Based on this, the applicant proposed an anti-sway mechanism and an active air intake grille with the mechanism to solve the above technical problems. Utility Model Content

[0005] The utility model aims at the deficiencies in the prior art and provides an anti-swing mechanism and an active air intake grille with the mechanism to solve the above technical problems.

[0006] The utility model solves the problem through the following technical solutions:

[0007] An anti-sway mechanism includes support columns, which are fixedly arranged in pairs and are provided with insertion holes. It also includes an insert sheet, the front end of which passes through the insertion holes of the two support columns, the front end of which is provided with a three-point buckle, and the rear end of which is provided with a limit baffle. The three-point buckle and the limit baffle are respectively engaged with the two support columns to achieve a fixed connection.

[0008] Preferably, the three-point buckle includes a main buckle arranged in the middle of the front end of the plug-in piece, and also includes side buckles symmetrically arranged on both sides of the front end of the plug-in piece, and the main buckle and the two side buckles are respectively clamped on the three sides of the insertion hole.

[0009] Preferably, the middle portion of the insert is hollowed out and provided with a plurality of reinforcing ribs.

[0010] Preferably, the contact distance between the main buckle and the support column is 1 mm.

[0011] Preferably, the contact distance between the side buckle and the support column is 0.3 mm.

[0012] Preferably, the assembly clearance between the two side surfaces of the inserting piece on which the side buckles are provided and the insertion hole is 0.4 mm.

[0013] Preferably, the assembly clearance between the side surface of the insert sheet on which the main buckle is provided and the insertion hole is 0.2 mm.

[0014] Preferably, an assembly gap between the side surface of the insert sheet opposite to the main buckle and the insertion hole is 0.3 mm.

[0015] An active air intake grille with an anti-swing mechanism comprises a main frame, a plurality of blades are movably arranged on the main frame, a motor is fixedly arranged in the middle of the main frame, a driving rod is arranged on the motor, a connecting rod is movably connected to the end of the driving rod, the connecting rod is rotationally connected to the blades, the blades move synchronously through the connecting rod, the anti-swing mechanism is also arranged on the main frame, and the anti-swing mechanism is located in the middle of the driving rod.

[0016] Preferably, the driving rods are respectively arranged on both sides of the motor and are synchronously driven by the motor.

[0017] Preferably, a limiting protrusion is provided on the driving rod, and the limiting protrusion is limited by the two supporting columns.

[0018] The beneficial effects of the utility model are:

[0019] 1. Significantly improved stability: The unique three-point buckle and limit baffle combination ensures a stable connection between the insert and the support column, effectively limiting the swing of the drive rod in the active air intake grille. Especially when the vehicle encounters complex road conditions during driving, it can still maintain high stability and reliability;

[0020] 2. Reduce mechanical wear: Reduce the relative movement between mechanical parts caused by the swing of the drive rod, thereby reducing the wear rate, extending the service life of parts, and reducing maintenance and replacement costs;

[0021] 3. Improve economic efficiency: The insert is made of PP-GF30 material, which not only has good mechanical properties but also has cost advantages. Combined with the design of hollowing out the middle and reinforcing ribs, it not only reduces the overall weight, but also reduces the material cost, and does not affect the structural strength, thus improving the economic efficiency of the product;

[0022] 4. Enhanced synchronization and precision: Since the anti-sway mechanism effectively limits the swing of the drive rod, the blades can achieve more synchronous and precise opening and closing movements under the drive of the motor, improving the overall performance of the active air intake grille;

[0023] 5. Simple design, easy to install and maintain: The structural design of this utility model is simple and clear, the process is controllable, suitable for industrial mass production, and the installation process is convenient and quick.
