The transmission scheme design of the actuator of the hidden door handle telescopic system of the car

Nowadays, cars have entered thousands of households and have become one of the indispensable means of transportation. There are more and more car manufacturers, and the competition is becoming more and more fierce. In order to gain more market share, developers use their unlimited imagination to truly let everyone feel the technology. The technical process is constantly improving, and the configuration on the car is more abundant. The appearance of the car has a stronger three-dimensional sense and smoother lines. In order not to damage the beautiful appearance, the invention of the hidden door handle has solved this problem very well. How does the hidden door handle of a car complete a series of movements, mainly driven by actuators? What structures does the actuator contain?

The actuator of the concealed door handle telescopic system of the car includes motors, worms, helical gears, screw rods, nuts, and actuator housings.

The working principle of the actuator of the hidden door handle telescopic system of the car: the motor generates rotational motion after receiving the instruction from the PCB, and the worm screw installed on the output shaft of the motor drives the helical gear to rotate, and the rotation of the helical gear drives the helical gear. The worm rotates, and I tell you that it drives the helical gear meshed with it to rotate. At this time, the rotation of the helical gear drives the screw that is integrated with it to rotate, and the screw drives the nut that matches it to make a linear motion, pushing the door handle from the back Do push and pull movements, and finally complete the entire working process. The hidden door handle telescopic system actuator transmission scheme of this car has the characteristics of light structure, large torque, low noise and self-locking function.
