Specifically, the bracket module 20 - 1 includes a flap support bracket 20 , a flap cover bracket 30 , a mounting bracket 40 , and a movement guide 50 .

For example, the flap support bracket 20 is positioned as a lower portion of the flap 10 to fix the flap 10, and is moved forward and backward linearly and clockwise/counterclockwise with the flap 10. The flap cover bracket 30 is positioned as an upper portion of the flap 10 to surround the flap 10 , and is rotated clockwise/counterclockwise together with the flap 10 .

To this end, the flap cover bracket 30 is coupled to the right mounting bracket 40-2 and the guide member 50 of the mounting bracket 40 while surrounding the upper portion of the flap 10 so that the side of the flap 10 is It consists of a bracket frame 31 having one side wrapped around it, and a bracket extension part 33 positioned on the flap rotation module 70 by forming the other side of the bracket frame 31 .

In particular, the left mounting bracket 40-1 is provided with a bracket restraining part 41 (refer to FIG. 3) is formed, and the bracket restraining part 41 is provided as a place where some components of the flap moving module 60 are mounted. do.

For example, the guide member 50 includes a left guide member positioned in the left mounting bracket 40-1 and a right guide member positioned in the right mounting bracket 40-2. Therefore, the guide member 50 is fixed to the actuator housing 70-1 of the flap rotation module 70 through the guide slot of the left mounting bracket 40-1, and the guide slot of the right mounting bracket 40-2. The flap 10 and the flap cover bracket 30 are fixed to the overlapped side portion through the. In particular, the guide member 50 may apply a roller, but a guide rail may be applied, or a structural change capable of reducing friction in a linear motion may be applied.

Therefore, the guide member 50 reduces the contact friction between the components when the flap 10 moves forward and backward linearly and clockwise/counterclockwise rotation to enable smooth movement.

Specifically, the flap movement module 60 uses the actuator housing 70-1 (refer to FIG. 3) of the flap rotation module 70 as an assembly site, and the electromagnetic force and elastic force generated between the electromagnet and the permanent magnet by power supply. The flap 10 and the flap cover bracket 30 are moved forward and backward by generating a linear movement force with .

For example, the elastic force generating member is made of an elastic member (63). The elastic member 63 is divided into a support spring 63-1 and a bracket spring 63-2. The support spring 63-1 is compressed by the movement of the rear permanent magnet 62 pulled by the generation of electromagnetic force, and returns the rear permanent magnet 62 to the initial right tooth with elastic restoring force due to tension when the electromagnetic force is released to return to the restrained state. makes it On the other hand, the bracket spring 63-2 pulls the spring to the actuator housing 70-1 in a state of releasing the fixing force between the bracket restraining part 41 of the left mounting bracket 40-1 and the rear permanent magnet 62 by electromagnetic force. Apply spring push force.

For example, the movement position sensing member includes a rear switch 64 , a front switch 67 , and a switch protrusion 68 .

In this case, the rear switch 64 is located in the bracket restraint portion 41 of the left mounting bracket 40-1 to provide a contact signal by pulling movement of the actuator housing 70-1 and a contact release signal by pushing movement. The battery power supply/disconnection is made to the rear moving electromagnet 61 by transmitting it to the flap controller 1-1. On the other hand, the front switch 67 is located in the actuator housing 70-1 to generate a contact signal due to the pushing movement of the actuator housing 70-1 and a contact release signal due to the pulling movement. By transmitting to 1), the battery power supply/disconnection is made to the forward moving electromagnet 65 .

In particular, the switch protrusion 68 protrudes from the inner surface of the cover grill 3 and is arranged to face the front switch 67 so that the front switch 67 is in contact and non-contact with the moving distance of the actuator housing 70-1. to be converted to

Referring back to FIG. 3 , the flap rotation module 70 includes an actuator housing 70 - 1 , a motor 71 , and a link 73 .

For example, the actuator housing 70-1 uses the protrusion structure of the rear permanent magnet 62 by attaching the rear permanent magnet 62 of the flap moving module 60 to the bracket restraint portion of the left mounting bracket 40-1. A binding force is formed with respect to (41), and an electric circuit such as a printed circuit board (PCB) for the motor 71 and control is embedded.
