[0002] Manual tilt screen: installed in the center console of the car, the central control display screen can be manually rotated within a specified angle in the left and right directions through a mechanical structure to meet the driver or passenger's needs for different screen orientation angles.

[0003] Driven by the recent wave of intelligent automotive products, a new demand for dynamic in-vehicle displays has emerged. This demand requires displays that can be rotated or moved within the interior through mechanical mechanisms, enhancing product practicality and driving comfort. This article addresses this market demand by proposing a technical solution for manually tilting displays.

[0004] Although motor-driven tilt screens are available on the market, they are expensive and unsuitable for most car manufacturers seeking to reduce costs. Manual tilt screens also face a series of specific challenges and requirements, including:

[0005] 1. Quiet and comfortable: In a relatively closed vehicle environment, the manual tilt screen should not produce any noticeable noise or abnormal sound, ensuring no noise disturbance to the driver and passengers, providing a comfortable driving experience.

[0006] 2. Compact space design: Given that vehicle interiors are typically compact, the tilt screen's rotation mechanism must be small and compact to fit within the limited interior space.

[0007] 3. Structural stability: During driving, the deflection screen and its mechanism must be able to withstand complex environments such as impact and vibration to ensure there is no shaking, looseness or abnormal noise to ensure driving safety;

[0008] 4. Excellent damping performance: After the user rotates the deflection screen multiple times, its damping should not deteriorate or decay significantly, providing a stable interactive experience;

[0009] 5. Anti-destruction design: Since the display screen is a component that users frequently operate and touch in daily life, the yaw mechanism must have a protective design to prevent damage to the internal transmission structure caused by abnormal external impact forces to ensure long-term stable operation.

[0010] 6. High reliability: The yaw mechanism must meet the reliability and life requirements of vehicle-mounted products to ensure stable operation in harsh environments.

[0011] To address these challenges and requirements, this technical solution provides a structure specifically designed for manual tilting of in-vehicle displays. This innovative structure enables the display's left-right rotation, demonstrating its originality while fully meeting the stringent requirements of automotive products. Utility Model Content
