TJX24RD DC Gear Motor for Automotive Screen Rotation: Mini Precision Core, Driving Flexible Screen Motion with Stable Reliability

The TJX24RD DC gear motor is a vehicle-grade customized micro drive component tailored for automotive screen rotation mechanisms, integrating ultra-compact structural design, vehicle-grade stable torque output, low-noise precision transmission and anti-vibration anti-shock engineering. Powered by 12V automotive standard low-voltage power supply (compliant with automotive electrical system specifications), it achieves precise angular rotation, stepless speed regulation and self-locking stable positioning, supporting core functions of automotive central control rotating screens/navigation screens such as 0-90° free rotation, one-key angle positioning, intelligent memory adjustment and anti-jamming reverse protection for household cars, SUVs and new energy vehicle interior intelligent systems. It meets the stringent vehicle-grade requirements of automotive screen rotation mechanisms for drive precision, structural miniaturization, vibration resistance and long-term reliability in complex automotive working environments such as vehicle vibration, temperature changes and voltage fluctuations, and matches the intelligent and humanized use needs of automotive interior electronics.

Working Principle

Automotive screen rotation mechanisms rely on the TJX24RD motor as the core power source for precise angular drive and stable positioning—the key to realizing flexible, quiet and reliable rotation of the central control screen. The motor converts the 12V DC power of the automotive electrical system into uniform, low-speed mechanical rotation via its optimized multi-stage precision micro-gear reduction system and high-efficiency vehicle-grade electromagnetic structure, and cooperates with the screen’s internal worm and gear transmission mechanism (with self-locking function) to convert rotary motion into precise angular rotation of the screen body, with a customizable rotation speed of 5-15°/s and output torque of 0.5-2.0N·m, perfectly matching the load of automotive central control screens of different sizes (7-15 inches). When the driver/passenger triggers the rotation command (physical button/voice control/ touch screen), the motor drives the screen to rotate stably to the preset angle (0° vertical/45° tilt/90° horizontal) with calibrated speed, and the self-locking performance of the gear transmission mechanism ensures the screen is firmly positioned at the target angle without sliding due to vehicle vibration, braking or bumping. The motor is integrated with the automotive central control intelligent system, with real-time angular position sensing feedback and anti-jamming protection: when the screen rotation encounters obstacles (foreign objects/mechanical jamming), the motor automatically reverses and stops output to avoid structural damage to the screen or motor; it also supports intelligent memory function, recording the last used screen angle and restoring it with one key at the next startup. The vehicle-grade circuit design of the motor adapts to the voltage fluctuation of the automotive electrical system (9-16V), ensuring stable operation during vehicle startup, idling and high-speed driving.
