Background
The electric seat can be adjusted by controlling the motor to adjust the front and back position, the up and down height and the backrest angle of the seat, and the electric seat is more luxurious and can also adjust thigh support, waist support and the like.
The whole system of the electric seat is generally composed of a bidirectional motor, a transmission device, a seat adjuster and the like. The motors mostly adopt permanent magnet type motors with small volume and large power, and are generally controlled by a switch arranged on a left seat side plate or a left door handrail, and the switch can enable one motor to move in different directions. After the switch is switched on, the power of the motor drives the flexible shaft to rotate through the gear and the driving shaft, and then the seat adjuster is driven to move. When the regulator reaches the end of the travel, the flexible shaft stops rotating, so that the motor still rotates, and the power of the motor is absorbed by the rubber coupling to prevent the motor from being overloaded and damaged in case the seat is clamped. When the control switch is powered off, the return spring can separate the plunger of the solenoid valve from the claw-shaped joint and return the plunger to the original position. To prevent overloading of the motor, most permanent magnet motors incorporate fuses. The number of motors depends on the type of power seat, and four motors are usually installed for two-way moving seats, and the power seat can use up to eight motors.
The transmission device of the electric seat comprises a speed changer, a coupling device and an electromagnetic valve. The seat regulator consists of screw jack and gear transmission mechanism. A coupling is arranged between the motor and the speed changer, and the transmission device and the seat adjuster are connected by a flexible shaft. The requirement on the seat shaft is not high, and the current factory mainly uses precision equipment to process the seat shaft, so that the precision equipment is high in cost, a numerical control operator is required to operate and control the seat shaft, a large amount of cost is wasted, and equipment which is low in cost and can grind the spherical surface of the seat shaft in batches is required.
