Abstract
A power trunk device includes a hinge arm coupled to a trunk lid and configured to be rotatably coupled to a vehicle body panel to define a trunk space, the hinge arm being configured to open and close the trunk lid, a torsion bar link rotatably coupled to a middle of the hinge arm, a torsion bar connected between the torsion bar link and the vehicle body panel in front of the hinge arm, the torsion bar being configured to provide elastic force in a direction in which the trunk lid is opened, and an electric drive unit connected between the hinge arm and the torsion bar, the electric drive unit being configured to be moved together with the hinge arm while providing rotational force to the hinge arm.
Claims20
Power trunk device comprising:
- a hinge arm coupled to a trunk lid and configured to be rotatably coupled to a vehicle body panel to define a trunk space, the hinge arm being configured to open and close the trunk lid;
- a torsion bar link rotatably coupled to a middle of the hinge arm;
- a torsion bar connected between the torsion bar link and the vehicle body panel in front of the hinge arm, the torsion bar being configured to provide elastic force in a direction in which the trunk lid is opened;
- and
- an electric drive unit connected between the hinge arm and the torsion bar, the electric drive unit being configured to be moved together with the hinge arm while providing rotational force to the hinge arm, wherein the electric drive unit is configured to be rotatable relative to the hinge arm when the hinge arm is rotated and wherein the electric drive unit comprises:
- a motor assembly comprising a motor configured to provide rotational force to the hinge arm and a rotary shaft provided at a first end of a motor housing, the rotary shaft being configured to be rotated in a state of being interlocked with the motor;
- a first motor bracket having a first end coupled to the middle of the hinge arm and a second end coupled to the rotary shaft;
- and
- a motor link having a first end rotatably coupled to a second end of the motor housing and a second end configured to be rotatably caught by a lower end of the torsion bar.
