Passenger car seat power unit

1. Core functions and application scenarios

core functionality

Multi-directional precise adjustment: It supports electric adjustment in 6 or more directions, including seat forward and backward sliding, vertical lifting, seat cushion tilt, backrest pitch, lumbar support, and headrest height/angle, adapting to the ergonomic sitting posture of drivers and passengers of different heights and body types.

Smooth and silent drive: The motor is integrated with the worm gear/planetary gear, ensuring no stalls, no vibrations, and low noise (≤55dB) during operation. The adjustment speed is uniform and smooth, guaranteeing a quiet ride for long journeys.

Intelligent safety protection: Equipped with four major mechanisms: built-in overload protection, overcurrent protection, anti-pinch protection, and limit self-locking. It automatically stops when adjusted in place and instantly halts upon encountering obstacles, effectively preventing pinching injuries and component damage.

Convenient control mode: Equipped with panel buttons, wireless remote control, seat memory (capable of storing 3 sets of positions), and other control methods, it features one-key reset and quick switching, catering to the high-frequency usage needs of both drivers and passengers.

Applicable scenarios

Long-distance tourist bus: It caters to passengers' needs for prolonged sitting posture adjustments and semi-reclining rest, enhancing the comfort of the journey.

City bus/passenger bus: Equipped with high-frequency adjustment for driver's seat, optimizing driving posture and alleviating driving fatigue.

High-end business passenger vehicles/RVs: Support for multifunctional expansion of luxury seats, matching a high-quality cabin experience.

School buses / special passenger vehicles: Designed with high stability and high safety to ensure the safety of special groups.

II. Core Advantages of the Product

1. Strong and stable power

Equipped with a 24V DC permanent magnet brushless motor (optional 12V), it boasts high power density and ample torque (rated torque 15–45N·m), ensuring smooth and consistent performance under full load conditions without any stalling or degradation.

Pure copper winding + precision bearings, capable of continuous operation for 10,000 hours without failure, anti-aging, and resistant to high and low temperatures (-40℃~85℃), suitable for various road conditions and climates.

The integrated valve block and sealing structure are free from oil leakage, loosening, and abnormal noise, and have passed a 50,000-cycle life test.

2. Precise and efficient transmission

Equipped with a planetary gear/worm gear reduction mechanism, it boasts a transmission efficiency of ≥92%, a positioning accuracy of ≤±1mm, and precise and controllable adjustment angles.

Lightweight and compact design (with a 30% reduction in volume and a 25% reduction in weight) is suitable for installation in narrow spaces such as seats, without occupying space in the car interior or luggage compartment.

The dual-drive solution with flexible shaft/rigid shaft is optional, adapting to different seat structures, offering flexible installation and strong universality.

3. Safe, durable, and reliable

The all-metal casing, coupled with high-strength engineering plastics, is resistant to impact and vibration, and has passed rigorous tests including strong bus vibration, salt spray, dustproof, and waterproof (IP65) testing.

Equipped with a built-in temperature sensor and current monitoring module, it automatically powers off in case of abnormal operating conditions, ensuring the safety of the circuit and motor.

Maintenance-free design, with core components requiring no maintenance for 5 years or 800,000 kilometers, reducing vehicle operation and maintenance costs.

4. Smart compatibility and adaptability

Supporting CAN bus communication, it can be integrated with the entire passenger car control system to achieve intelligent functions such as seat adjustment, fault diagnosis, and status feedback.

Compatible with mainstream bus seat brands (Yutong, Golden Dragon, Higer, etc.), it can be installed and used immediately without the need to modify the seat frame, suitable for both upgrade and new installation scenarios.

It can be expanded with functional interfaces for heating, ventilation, massage, vibration reminders, etc., meeting the multifunctional upgrade of seats.
