  • Patent number: 12263735
    Abstract: A hybrid driving module includes a rotor with a hub ridge provided on a rotor hub to enable vibration noise to be reduced, and the hub ridge supports the rotor in a state in which the hub ridge is fastened to the rotor hub. The hybrid driving module may further include a ridge fixing structure that prevents the hub ridge from separating from the rotor hub. For example, the ridge fixing structure may be a ridge snap ring. The hybrid driving module may further include an elastic body that elastically presses the hub ridge toward the ridge snap ring. The elastic body may elastically press the rotor in the axial direction. The elastic body may also serve as a return spring of the piston plate of the engine clutch.

  • Patent number: 12257903
    Abstract: The present invention relates to a hybrid driving module, in which an input member is aligned in a radial direction and/or an axial direction by a rotor hub, and thus the hybrid driving module may be easily assembled and ensure the high axial balance and the operability and durability of the engine clutch. In the hybrid driving module, the input member may be aligned at least in the radial direction or in the axial direction by a central shaft extension part of the rotor hub. A bearing configured to support a rotation and thrust may be installed between the central shaft extension part and the input member. The input member may be supported to be rotatable relative to a housing. The input member may be aligned in the radial direction and/or the axial direction by the housing.

  • Patent number: 11970592
    Abstract: The present invention relates to a window cover film and a flexible display panel including the same. More particularly, the present invention relates to a window cover film including a base layer and a hard coating layer, and a flexible display panel including the same. Since the window cover film of the present invention has high surface hardness, flexibility, the excellent bending properties, the window cover film may be restored to the original form without permanent deformation and/or damage of the hard coating layer and the window cover film even though a predetermined deformation is repeated.
