Description

Actuator with modular gear box

The present invention relates to an actuator equipped with a modular gear box, and more particularly, by combining the reduction gear and the driving motor integrally, it is possible to simplify the process such as assembly work and to maintain the noise and performance constant. It relates to an actuator equipped with a modular gear box that can reduce management costs through unification of specifications.

In general, an air conditioning system is installed in a vehicle to comfortably maintain the indoor temperature, humidity, air cleanliness, and flow of the vehicle. Such an air conditioning system is roughly classified into an air conditioner and a heater. In general, an air conditioner is used in summer and a heater is used in winter.

The air conditioning system of such a vehicle is largely equipped with various modes, such as an intake, a mode, and a temp.

The intake function is a function of introducing outside air into the vehicle interior or circulating air inside the vehicle.

The mode function is a function of controlling the wind direction of air exiting from the duct of the air conditioning system to the outlet on the vent, floor, or rear seat side.

Temp function is a function to control the flow of air flowing in the duct of the air conditioning system to form the air of the desired temperature, that is, the cold or warm air by the driver to enter the room.

These functions are performed by an electric control unit (ECU) provided in a vehicle operating an actuator installed on a blower unit constituting an air conditioning system of the vehicle.

Hereinafter, a vehicle actuator according to the related art will be described with reference to FIG. 1.

As shown, the vehicle actuator according to the prior art, the case 10a molded in a predetermined shape so that various components are mounted therein, a cover 10b covering and coupling the case 10a, the combined case Drive motor 20, which is mounted in the housing (11a) consisting of a 10a and the cover (10b) is connected to the drive motor 20, the drive motor 20 to rotate forward or reverse in accordance with the electrical signal of the control device, interlocked and interlocked with each other The

gearbox

40, 50, 60 of the output gear, the output gear 30 for rotating the damper door by interlocking with the reduction gears (40, 50, 60), and a connector connected to a control unit such as a power supply and an ECU Terminal 70 or the like.

The vehicle actuator configured as described above rotates the drive motor 20 by receiving an angle signal from the ECU and rotates the output gear 30 through the

reduction gears

40, 50, and 60 to rotate the door in the blower unit by a predetermined angle. It becomes possible.

But. According to the prior art as described above, as the shapes of the case 10a and the cover 10b vary according to the vehicle type, the position of the reduction gear, etc. had to be adjusted separately, so that the development work of the vehicle actuator itself was complicated.

In addition, since the plurality of reduction gears (40, 50, 60) and the drive motor (20) had to be assembled separately in the case (10a) during assembly, there was a disadvantage in that the process such as assembly work becomes complicated.

In particular, due to the different types of reduction gears, there is a problem in that an assembly error occurs, such as an improper assembly load due to inadequate meshing between gears in the process of assembling them one by one. .

Moreover, according to the related art, not only the specifications of the actuators applied to various models are different, but also the components are difficult to manage due to different specifications of the components. Accordingly, when any one of the parts is damaged, there is also a lot of work to find and replace the corresponding parts. The disadvantage was that it takes time and effort.

In addition, according to the prior art, the distance between the shaft between the reduction gear is also changed according to the actuator according to the difference between the drive motor and the reduction gear included in the various actuators applied to the various vehicles to maintain the noise and performance of the actuator to be constant It also had the disadvantage that it needed additional measures to adjust it.
