Description

Pivoting structure and electronic device having the same

The present invention relates to a pivoting structure, and in particular, to a pivoting structure that is applied to an electronic device and has a synchronous rotation function.

Existing folding screen products, such as tablet computers or smart phones, usually only have a simple tablet mode and a folding mode, wherein the tablet mode is used for work or entertainment, and the folding mode is used for storage. Therefore, the existing folding screen products lack other usage modes, so the existing folding screen products are limited in use.

In addition, most of the existing folding screen products use a hinge structure to connect the two bodies, the two bodies are used to carry the flexible screen and are switched between the flat mode or the folding mode through the relative unfolding and relative folding of the two bodies. The existing hinge structure usually uses a solid pivot as the rotation axis, so a space for accommodating the hinge structure needs to be reserved between the two bodies to avoid interference between the two bodies during the unfolding and folding process.

Therefore, in the flat panel mode of the existing folding screen products, a gap is formed between the two bodies and a part of the hinge structure is exposed, so it has the disadvantage of being unsightly.

The present invention provides a pivoting structure suitable for an electronic device, which has the effect of synchronous rotation and is suitable for eccentric rotation along two axes.

A pivoting structure of the present invention includes a cover body, a first carrier board, a second carrier board, a synchronous hinge and at least one eccentric hinge. The first carrier plate is located above the cover body. The second carrier is located above the cover and adjacent to the first carrier. The synchronous hinge is disposed on the cover body and is respectively connected to and synchronously drives the first carrier board and the second carrier board. At least one eccentric hinge is disposed on the cover body and is respectively connected to the first carrier plate and the second carrier plate. The first carrier plate and the second carrier plate respectively pivot relative to the cover body synchronously with a first axis and a second axis passing through the synchronous hinge and at least one eccentric hinge as the center, and then switch to the unfolding mode or the closing mode.

The invention provides an electronic device, which can narrow the gap between the first body and the second body when the electronic devices are unfolded to each other, hide the pivoting structure in the first body and the second body, and present a flat appearance.

An electronic device includes a first body with a first space, a second body with a second space, and a pivot structure disposed between the first body and the second body and located opposite the first space and the second space . The pivoting structure includes a cover body, a first carrier board, a second carrier board, a synchronous hinge and at least one eccentric hinge. The first carrier board is located above the cover body and is connected to the first body. The second carrier board is located above the cover body and adjacent to the first carrier board, and is connected to the second body. The synchronous hinge is disposed on the cover body and is respectively connected to and synchronously drives the first carrier board and the second carrier board. At least one eccentric hinge is arranged on the cover body and The first carrier board and the second carrier board are respectively connected. The first carrier plate and the second carrier plate respectively pivot relative to the cover body synchronously with a first axis and a second axis passing through the synchronous hinge and at least one eccentric hinge as the center, and then switch to the unfolding mode or the closing mode. In the unfolding mode, the first body and the second body have an included angle, and in the closed-closing mode, the first body and the second body overlap each other.

Based on the above, in the pivoting structure of the present invention, through the synchronous hinge, the first carrier plate and the second carrier plate are respectively pivoted relative to the cover body synchronously around a first axis and a second axis, so as to quickly switch to unfolding. The mode and the closed-close mode, in addition, at least one eccentric hinge is used to limit the rotation travel of the first carrier board and the second carrier board, so as to prevent the first carrier board and the second carrier board from shaking.

Further, the first body and the second body of the electronic device of the present invention are connected to the synchronous hinge of the pivot structure and at least one eccentric hinge through the first carrier board and the second carrier board. When the first body and the second body are unfolded to 180 degrees from each other, the first carrier plate and the second carrier plate are driven to rotate in opposite directions, and at the same time, the pivot structure is hidden in the first body and the second body. Since the first carrier plate and the second carrier plate rotate eccentrically relative to the cover body along the first axis and the second axis respectively, the effect of flat appearance can be achieved after the first body and the second body are unfolded 180 degrees.

Referring to FIG. 1B and FIG. 2B , when an external force is applied to the first body 210 or the second body 220 , the first carrier plate 120 and the second carrier plate 130 turn toward the first rotation direction R1 and the second rotation direction R2 respectively. The meshing effect of the first rack T1 , the second rack T2 , the two first gears 1451 and the two second gears 1452 makes the first body 210 and the second body 220 respectively center on the first axis L1 and the second axis L2 And it pivots synchronously and has an included angle A.

To sum up, the pivot structure of the present invention enables the first carrier plate and the second carrier plate to pivot synchronously relative to the cover body with a first axis and a second axis as the center respectively through the synchronous hinge, so as to quickly switch In the unfolding mode and the closing mode, at least one eccentric hinge is used to limit the rotational strokes of the first carrier plate and the second carrier plate, so as to prevent the first carrier plate and the second carrier plate from shaking.

Further, the first body and the second body of the electronic device of the present invention are connected to the synchronous hinge of the pivot structure and at least one eccentric hinge through the first carrier board and the second carrier board. When the first body and the second body are unfolded to 180 degrees from each other, the first carrier plate and the second carrier plate are driven to rotate in opposite directions, and at the same time, the pivot structure is hidden in the first body and the second body. Since the first carrier plate and the second carrier plate rotate eccentrically relative to the cover body along the first axis and the second axis respectively, the effect of flat appearance can be achieved after the first body and the second body are unfolded 180 degrees.

In addition, after the first body and the second body are unfolded, the gap between them can be narrowed, and the pivoting structure can be hidden in the first space and the second space, so as to improve the overall appearance of the electronic device. The use of a solid shaft makes the flexible panel suitable for flatly bearing on the first body and the second body, so as to avoid the defects of uneven surface or difficult assembly caused by the interference of the solid shaft.
