Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an actuator for an electronic parking brake device, and more particularly, to an actuator for an electronic parking brake device capable of improving assembly, miniaturizing a product, reducing vibration and noise, and preventing water penetration. It is about.
In general, the actuator is an actuator for moving a rotatably installed member or a slidably installed member, such as a door installed inside a duct of an air conditioner, and a friction member of a parking brake device that restrains a wheel of a vehicle. Is installed for driving a member that is difficult to drive directly.
In particular, the actuator installed in the electronic parking brake device must maintain a state in which the friction member restrains the rotation of the wheel, so that the driving force must be transmitted to the output shaft of the actuator even after the brake device is operated.
In addition, since the vehicle must be prevented from being moved by the slip of the friction member after the operation of the brake device is started, the driving force transmitted from the actuator to the friction member requires a high output driving force of a predetermined value or more.
Background art of the present invention is disclosed in Republic of Korea Patent Publication No. 10-2010-0008512 (January 26, 2010, the title of the invention: caliper integrated electronic parking brake device with an emergency release function).
In general, an electric parking brake actuator has a problem in that the output shaft is separated when driven for a long time because high power is applied to the output shaft, and the structure of the actuator is complicated because the support member is installed to suppress the output shaft from being separated. There is a problem that is difficult to reduce.
In addition, since the actuator for the electronic parking brake apparatus according to the prior art is output at a high rotational force to perform the locking operation, noise and vibration are generated by the collision between the gear teeth at the beginning of the operation and when the locking operation is completed. There is this.
In addition, the actuator for an electronic parking brake apparatus according to the prior art has a problem that when the vehicle is running in the rain or when washing the car, moisture introduced into the case is introduced into the motor and malfunction and breakage may occur.
Therefore, there is a need for improvement.
The present invention has been made to improve the above problems, the assembly is improved, the product can be miniaturized, the vibration and noise can be reduced, the actuator for the electronic parking brake device that can prevent moisture ingress The purpose is to provide.
In order to achieve the above object, the present invention, the motor is installed, the first case in which the output unit is received; A power transmission unit connecting the motor and the output unit and a housing accommodated in the output unit and seated in the first case; A second case coupled to the first case and constraining the housing; A motor case coupled to the first case and constraining the motor; And it provides an actuator for an electronic parking brake device, characterized in that it comprises a direction holding portion for allowing the motor to be seated in a predetermined direction on the first case.
In addition, the outer wall of the first case is characterized in that the motor insertion unit is coupled to the motor and the motor case is formed.
In addition, the direction maintaining portion, the engaging projection formed on the motor insertion portion; And a coupling groove formed in the motor and into which the coupling protrusion is inserted.
The coupling protrusion may include: a first protrusion formed at the motor insertion part and having a step formed therein; And a second protrusion formed at the motor insertion part and formed to have a different size from the first protrusion.
In addition, the coupling groove portion, the first groove portion is inserted into the first projection is formed step; And a second groove portion into which the second protrusion is inserted.
The actuator for the electronic parking brake apparatus according to the present invention has a motor case made of a separate material, and the motor and the power transmission unit are coupled to the other side of the case, respectively, so that the assembly of the motor is not considered when designing the mounting position of the power transmission unit. Is improved and the product can be miniaturized.
In addition, since the actuator for the electronic parking brake apparatus according to the present invention is provided with a housing in which the power transmission unit and the output unit are housed, between the threads at the moment when power transmission starts or when the brake device is completed, the power transmission is stopped. There is an advantage that the noise generated by the collision can be suppressed from occurring outside the case.
In addition, the actuator for the electronic parking brake apparatus according to the present invention has an advantage that the assembly of the actuator is facilitated by the easy connection of the motor and the connector because the connection plate is engaged with the terminal of the motor is installed.
In addition, the actuator for the electronic parking brake apparatus according to the present invention has an advantage that the size of the actuator can be reduced by reducing the size of the assembly of the power transmission unit and the output unit because the output unit is inserted into the seating portion of the second reduction gear.
In addition, the actuator for the electronic parking brake apparatus according to the present invention is provided with an integrated buffer unit between the case and the housing to reduce the vibration generated in the motor and the output unit, the noise generated from the motor and the output unit is discharged to the outside It is prevented, and there is an advantage that can be prevented from entering the output unit and the motor along the gap between the case and the housing, the water flowing into the case.
In addition, the actuator for the electronic parking brake apparatus according to the present invention has an advantage of preventing the housing and the housing from being spaced apart by preventing the housing from twisting during the brake operation because the fixing rib pressurizing the housing is formed on the inner wall of the case.
In addition, the actuator for the electronic parking brake apparatus according to the present invention can prevent the malfunction and damage due to the misassembly of the motor, since the motor can be always coupled to the motor insertion portion in a constant direction by the direction holding portion, There is an advantage that can prevent the motor from being spaced apart from the motor insertion portion.
