Increase in demand for luxury vehicles, growth in need to offer improved customer convenience & comfort, and integration of connectivity & advanced features in vehicles are factors expected to contribute to the growth of this market. It is equipped with a sensor to control the operation of the liftgate through movement of hands or legs.
HANDSFREE TAILGATE LICENSE
Hands-free power liftgate can be activated by waving foot underneath the rear bumper, between the exhaust pipe & license plate. Hands-free power liftgate enables the user to open or close the vehicle’s liftgate with a simple kick movement of the foot. Shortage of electronic components has forced manufacturers to leave out features such as hands-free power liftgate from vehicles till the microchip shortage is addressed. Several automobile manufacturers faced shortage of electronic components and limited inventory resulting in delayed vehicle production. The impact of the COVID-19 pandemic has resulted in supply chain disruptions and shortage of microchips required for development of hands-free power liftgate. The COVID-19 crisis has created uncertainty in the market, leading to massive decline of supply chain, temporary shutdown of industries, and decline in overall production and sales in the automotive industry. The global hands-free power liftgate market was valued $1,127.9 million in 2020, and is projected to reach $2,355.9 million in 2030, registering a CAGR of 7.8%. When the tailgate encounters an obstacle, it can be automatically retracted to prevent the motor from being burned out and avoid accidental pinching or damage to the vehicle.Hands-Free Power Liftgate Market statistics 2022-2030: Qualified electric tailgate products should have the function of intelligent detection of obstacles and emergency braking. With regard to the operation of the electric prop, the electric spindle inside the prop drives the operation of the trunk spring. The thread spindle moves on the screw nut which fixed to the inside of the outer tube. The motor and gear in the inner tube drive a threaded spindle. The driving rod is composed of an inner tube and an outer tube. The basic structure of the electric tailgate is two mandrel drive rods. At the same time, the motor current consumption increases and the power supply to the motor is reversed, so that the trunk will move in the opposite direction. When the tailgate encounters obstacles, the motor speed drops below the set limit. The principle of anti-clamping is that the ECU monitor the speed of the motor. The plunger keeps in situ and maintains its original length, pushing the opening of the valve. At the same time, because of the function of the non-return valve, the oil pressure in the plunger chamber cannot be quickly discharged. When the force of the compressed valve spring cannot be generated and the tappet-to-valve clearance is smallest, the tappet will not move any more. The effective stroke of the tappet increases and the valve clearance decreases. With the operation of the engine, under the pressure of oil, the plunger chamber is filled with oil and then the plunger goes down. If the gap between the tappet and the valve is large, the valve will emit an abnormal sound. When the hydraulic tappet starts to work, there is no oil pressure in it and the tappet plunger is at the bottom. The work of the hydraulic rod mainly depends on the oil pressure, the gap between the tappet body and the seat hole, the gap between valve stem and the seat hole and non-return valve in the tappet. The damper plays an important part in the entire electric tailgate device. It will make the electric tailgate more reliable and safer. The damper can effectively prevent the power tailgate from being out of control, because the out-of-control phenomenon is caused by the attenuation of the bearing spring or the excessive bearing force during the movement and the damper can compensate or counteract the effect of spring force. The most important part of smart electric tailgate is the damper. To ensure that component material, production technology and quality control are all accorded with the demands of vehicle pre-installed
A motor, decelerator, load-bearing spring, transmission wire rod, dampers and other core components with good quality should be imported from abroad or be produced by a supplier with pre-installed qualification for automotive manufacture. First of all, the tailgate weight of cars and SUVs are different, so there are two categories: Double Pole and Single Pole. Let's talk about the working principle of the smart electric tailgate.
