Eccentric hinge and electronic device with the same

The present invention relates to a hinge, and particularly relates to an eccentric hinge that rotates along a virtual axis.

The existing notebook computer is composed of a display screen, a host, and a pivot module. The pivot module is used to connect the display screen and the host, so that the display screen and the host can be relatively expanded or closed relatively through the pivot module. However, the existing pivot module usually uses the pivot as the axis of rotation, so a space that can accommodate the pivot module must be reserved between the display screen and the host to avoid interference between the display screen and the host during the rotation.

In the conventional notebook computer in the unfolded state, there will be a gap between the display screen and the host, and part of the pivot module and the bracket are located between the display screen and the host and it is difficult to hide, so it has the disadvantage of being unsightly.

The present invention provides an eccentric hinge, which is suitable for rotating along a virtual axis. When applied to an electronic device, it can greatly reduce the host and the monitor when they are unfolded. The gap between the curtains.

The eccentric hinge of the present invention includes a main body seat, two fixed seats and a bracket. The two fixing seats are arranged on the main body seat and spaced apart to form a limiting groove. The bracket has a turning part and a bearing part. The steering part is slidably arranged on the main body seat and located between the two fixed seats. The bearing part is connected to the turning part and is located outside the main body seat. Wherein, the bracket rotates relative to the two fixed bases and the main base with a virtual axis as the center, and the steering part slides along a curved track in the limiting groove to protrude outside the main base and the two fixed bases or is accommodated in the main base and the main base. Between two fixed seats.

The invention provides an electronic device. When the electronic devices are unfolded, the gap between the host and the screen can be reduced, and the eccentric hinge can be hidden in the electronic device to improve the aesthetics of the electronic device.

The electronic device of the present invention includes a first body, a second body, a housing, and a plurality of eccentric hinges. The first body has a first space. The second body has a second space. The shell pair is located in the first space and the second space. A plurality of eccentric hinges are arranged on the housing and respectively connect the first body and the second body. Each eccentric hinge includes a main body seat, two fixing seats and a bracket. The two fixing seats are arranged on the main body seat and spaced apart to form a limiting groove. The bracket has a turning part and a bearing part. The steering part is slidably arranged between the main body seat and the two fixed seats. The bearing part is connected to the turning part and is located outside the main body seat. Wherein, the plurality of brackets connected to the first body rotate around a first virtual axis, the plurality of brackets connected to the second body rotate around a second virtual axis, and the plurality of steering parts respectively follow a first curve The trajectory and a second curved trajectory slide to protrude outside the main body seat and the two fixed seats, or are stored in the corresponding main body seats and A fixed seat to drive the first body and the second body to close or expand each other.

Based on the above, in the eccentric hinge of the present invention, the steering portion of the bracket slides along a curved track in the limiting groove, and the bracket can rotate eccentrically with a virtual axis as the center, so that the bearing portion of the bracket is parallel to the base, or There is an included angle between the bearing part of the bracket and the base.

Furthermore, the first body and the second body of the electronic device of the present invention are respectively connected to a plurality of eccentric hinges. When the first body and the second body are expanded to 180 degrees each other, the multiple steering parts will be driven to slide along the first and second curved trajectories, respectively, so as to be accommodated between the respective main body seats and the plurality of fixed seats. At the same time, the eccentric hinge and the shell are hidden in the first body and the second body. In addition, each bracket rotates eccentrically, so that the first body and the second body are close to each other in the unfolded state, thereby reducing the gap between the two, achieving a better narrow-frame display effect and improving the aesthetics of the electronic device.
