The Automotive Power Liftgate System is a convenient and automated feature commonly found in modern vehicles, especially in SUVs and crossovers. It enables the automatic opening and closing of the rear trunk or tailgate through button presses or sensor-triggered actions, such as waving a foot under the rear bumper. This system utilizes electric motors and hydraulic mechanisms to smoothly and easily lift and lower the tailgate, making it easier for drivers to access the cargo area, particularly when their hands are full. The power liftgate system enhances user convenience and safety, often including adjustable height settings and obstacle detection features to prevent accidents during operation.
The power liftgate system is a mechanical device that opens and closes the vehicle's rear, powered by electric drive. It typically consists of an electric motor, transmission mechanism, control module, and sensors. Hydraulic and gas struts are common auxiliary devices used to support and balance the weight of the tailgate.
Single Rod power lift gate:
This system generally uses a single linear actuator or pneumatic piston for support and propulsion.
Its structure is relatively simple, typically comprising one support rod, one motor, and a gear system.
During operation, the motor transmits force to the support rod through the gear system, allowing the tailgate to be raised or lowered.
Single rod electric tailgates are common in lighter vehicles, providing automated tailgate functionality, though they may face limitations in larger SUVs and MPVs.
Dual Rod Power Tailgate:
This system employs two support rods or pneumatic pistons to assist in tailgate movement.
Its structure is more complex, providing greater stability and strength by distributing the load across two support points, making it better suited for larger and heavier tailgates.
Dual rod electric tailgates typically offer a greater range of opening heights due to their superior support capabilities.
This system is more commonly found in larger SUVs, MPVs, and luxury vehicles that require enhanced opening heights and reliability.
Touchless Operation: One of the significant innovations in electric liftgate systems is hands-free operation. Sensors, such as radar, ultrasonic, or infrared, detect a foot or specific movement beneath the rear bumper, allowing the tailgate to open or close without touching any buttons or handles. This feature is particularly useful when hands are full.
Obstacle Detection and Safety: Advanced electric liftgate systems are equipped with obstacle detection technology. Sensors can identify objects or individuals in the path of the closing tailgate, automatically stopping or reversing its movement to prevent accidents or damage.
Mobile Application Control: In vehicles equipped with mobile applications, users can remotely control the Smart Power Tailgate via their smartphones. This feature is especially beneficial for loading items from a distance.
The power liftgate system market is a rapidly growing sector. According to a report from Baijian Strategy, the market size is expected to reach $1.89 billion by 2023 and is projected to grow to $3.27 billion by 2030, with a compound annual growth rate (CAGR) of 7.49% from 2024 to 2030. Currently, electric liftgates are primarily installed in mid-to-high-end models, such as Tesla, Mercedes-Benz, Audi, Cadillac, and BYD Tang, with optional prices ranging from 3,000 to 5,000 yuan. The market penetration in China is currently below 20%. With ongoing advancements in smart integration technology, the market is expected to expand significantly in the future.
Growth of the Electric Vehicle Market: With the rapid growth of electric and hybrid vehicle markets, the demand for electric liftgates in these models is increasing. Manufacturers view electric liftgates as key selling points to attract consumers and enhance product competitiveness. Since 2020, Tesla has standardized electric liftgates across its entire model range.
Enhanced Vehicle Convenience and Comfort: Consumers are increasingly demanding convenience and comfort in their vehicles. The electric liftgate provides a user-friendly way to open and close the tailgate, improving the overall experience. This demand for convenience and comfort drives the development of the electric liftgate market.
Consumer Demand and Preferences: There is a growing consumer preference for advanced features and high-end configurations. Electric liftgates are perceived as luxurious and premium options, making them attractive in purchasing decisions. This consumer demand drives automakers to offer electric liftgates as part of their models.
Technological Advancements and Cost Reductions: As technology improves and costs decrease, the manufacturing and installation of electric liftgate systems have become more economically viable. This enables more automotive manufacturers to integrate electric liftgates into their models, creating more opportunities in the market.
