An air door actuator of an automobile air conditioner

Abstract

The invention discloses an air door actuator of an automobile air conditioner. The actuator comprises a first cover body, a second cover body, a motor, a PCB circuit board and conductive silica gel. The tail end of the motor is provided with two motor wiring terminals. One end of the PCB is provided with two first conductive terminals, and the other end of the PCB is provided with two second conductive terminals. One conductive silica gel is arranged between the first conductive terminal and the motor terminal opposite to the first conductive terminal, and the other conductive silica gel is arranged between the first conductive terminal and the motor terminal opposite to the first conductive terminal. The air door actuator uses the existing PCB technology skillfully, realizes the connection of the motor inside the actuator and the input function of the motor drive port, saves the high mold cost of the existing metal structural part integrated injection molding design, and can effectively reduce the material cost of the part by 60%.

Description

technical field [0001] The invention relates to an actuator, in particular to an actuator for an automobile air conditioner damper. Background technique [0002] The damper actuator of automobile air conditioner is composed of plastic shell, micro-motor, plastic gear set, position sensor (carbon film potentiometer), large gear output shaft and other components. The deceleration gear set and large gear output shaft are driven by the electric motor to rotate and drive Position sensor, the position sensor feeds back the voltage signal to the control unit (i.e. the car air conditioner ECU) to confirm whether it has reached the position and cut off the power, and realizes an angle output device of closed-loop control; [0003] In recent years, with the rapid development of my country's automobile industry, market competition and production cost pressures have increased sharply for auto parts suppliers. The current optimal motor connector component design for automotive air-condit...

Problems solved by technology

[0003] In recent years, with the rapid development of my country's automobile industry, market competition and production cost pressures have increased sharply for auto parts suppliers. The current optimal motor connector component design for automotive air-conditioning damper motor actuators adopts high-speed stamping Metal (or shrapnel) structural parts, and then injection molded into one, but this method needs to invest more than 100,000 high mold costs in the early stage. If purchased directly, the unit price of this motor connector component is about 1 yuan. higher
