Description

Double shaft synchronous twisting pivot

The present invention relates to a biaxial co-rotating torque pivoting device, which enables an electronic device assembling a biaxial pivot to rotate in synchronism when one of the pivots is rotated, and can be doubled by rotation of a single pivot. The action stroke makes the opening and closing of electronic equipment faster and more convenient.

For example, an electronic device such as a notebook computer generally includes a host system end (host) and a liquid crystal display screen end (top cover) that can be opened, and the two are pivotally connected at an opposite end. When in use, the liquid crystal display screen of the upper cover can be operated with the pivot axis as the action axis, or the two can be oppositely closed when not in use.

Such electronic devices such as notebook computers can be formed into a small volume when closed, which is convenient for the user to carry around. Compared with a typical desktop computer, such a folding electronic device has the advantage of high mobility and has been Marketing in the market for many years, especially the notebook computers produced and sold by related manufacturers in Taiwan are more important in the world.

However, the size of the tablet that the US company Apple announced in April 2011 was only about the size of the cover of the notebook computer, making it easier to carry around. The rise of tablets has affected the ecology and use of mobile electronic devices such as notebook computers. At present, there is a design that can separate the upper cover of the mobile electronic device from the host system end, so that the upper cover can be carried separately, having the advantages like a tablet computer, or through a double-axis pivot The settings of the upper cover and the main body can be bent at a larger angle to form a flat plate, providing a type of operation and use type such as a tablet computer.

The existing structure using the two-axis pivoting device mainly has a first rotating shaft rotating together with the upper cover, and a second rotating shaft rotating together with the main base, and at the same time, in order to enable the two rotating shafts to rotate synchronously, on the two rotating shafts There are related gear mechanisms, and related patents can be found in the Republic of China new patent M396575 "hinge structure" and M388823 "two-axis linkage type hinge". However, in the prior art, the pivoting device using the two-axis type is opened at a large angle, or when the display end of the upper cover and the base end of the main body are folded into an overlapping state, usually one of the axes is rotated to a specific angle, and then switched to another One axis rotates, and the folding operation of the upper cover and the main body is slow and not smooth.

The main purpose of this creation is to provide a two-axis co-rotating pivoting pivot, which enables the electronic equipment using such a biaxial pivot to be faster and more convenient due to the interlocking stroke, and makes the opening and closing operation of the electronic device more stable and smooth. .

In the illustrated embodiment, as shown in FIGS. 1 to 3, the present invention is provided with a first pivot 10 and an opposite second pivot 20, and the first pivot 10 and the second pivot 20 The fixing pieces 11 and 21 are respectively assembled at one end for being respectively combined and fixed on the display end of the upper cover of the electronic device (such as a notebook computer) and the base of the main body; the other ends of the first pivot 10 and the second pivot 20 are available. Sockets such as opposing cams and cams, resilient means, and fixtures together to form a desired pivot.

The first pivoting plate 13 and the second pivoting shaft 20 are provided with a first positioning partition 13 and a second positioning partition 14 which are spaced apart from each other by a predetermined distance, and the first positioning partitions 13 and The second positioning partitions 14 are respectively provided with upper and lower first through holes 131, 141 and second through holes 132, 142 for respectively passing through the first pivot 10 and the second pivot 20, in this embodiment, The first pivot 10 passes through the opposite first through holes 131, 141, and the second pivot 20 passes through the opposite second through holes 132, 142, while the first pivot 10 and the second pivot 20 are set to contain The cross-sectional shape of the cut plane, the first through holes 131, 141 and the second through holes 132, 142 are circular holes, and when the first pivot 10 and the second pivot 20 are rotated, the first positioning partition 13 and The second positioning partition 14 does not rotate with the first pivot 10 and the second pivot 20. At the same time, between the first positioning partitions 13 and the second positioning partitions 14 and between the first through holes 131, 141 and the second through holes 132, 142, respectively, support shaft holes 133, 143 are provided.

An intermediate support shaft 15 is disposed between the first positioning partition 13 and the second positioning partition 14 and pivotally connects the two ends 151 and 152 to the support shaft holes 133 and 143, respectively. The guide screw 16 of the specific thread is movably sleeved on the shaft of the intermediate support shaft 15 via a central hole 161 whose diameter is slightly larger than the diameter of the shaft of the intermediate support shaft 15.

A first lead screw 17 having a thread of a certain length is also disposed between the first positioning partition 13 and the second positioning partition 14 and is sleeved through the first positioning partition 13 and the second positioning partition 14 . The first pivot shaft 10 is coupled to the body and has a predetermined thread tooth coupled to the thread of the guide screw 16; a second thread is provided opposite to the first lead screw 17 The lead screw 18 is also disposed between the first positioning partition 13 and the second positioning partition 14 and is sleeved on the second pivot 20 shaft passing between the first positioning partition 13 and the second positioning partition 14 The body is interlocked and its predetermined thread is also toothed to the thread of the lead screw 16.

In the illustrated embodiment, the reverse thread may be, for example, when the thread of the first lead screw 17 is left-handed, and the second lead screw 18 is right-handed. At the same time, the preset central holes 171, 181 of the first lead screw 17 and the second lead screw 18 for the first pivot 10 and the second pivot 20 can be set to be the first pivot 10 and the second pivot The shaft 20 has the same cross-sectional shape as the shaft body (in this embodiment, the center holes 171 and 181 are also provided with inner holes having a flat surface) for forming a interlocking combined structure.

As shown in Figures 4 to 6, when the upper cover display end of the electronic device (such as a notebook computer) and the main body base are in a closed state (as shown in Figures 1, 3 and 5), the guide screw of the intermediate support shaft 15 16 is located on one side of the shaft body (on the left side of the embodiment, when one of the upper cover display end or the main base is rotated, the fixed pieces 11 and 21 are connected together to force the first pivot 10 and the second pivot 20 respectively. Rotating; taking the display end of the upper cover of the electronic device as an example, the first pivot 10 rotates synchronously with its fixed piece 11 to cause the first lead screw 17 to rotate in a clockwise direction as indicated by the arrow, and the lead screw 16 will be affected by The force rotates and interlocks to move to the other side of the shaft of the intermediate support shaft 15, and the rotating guide screw 16 will synchronously drive the second lead screw 18, causing the second lead screw 18 to generate a counterclockwise direction as indicated by the arrow. Rotating, the entire second pivot 20 is reversely rotated by force; that is, as long as one of the pivots is rotated by force, the other relative pivot is synchronously rotated in the opposite direction, for example, for electronic equipment (such as a notebook type) In the case of the computer, when the display of the upper cover is opened, the base of the main unit is synchronously reversely deployed. If the display end of the upper cover is turned 90 degrees, the base of the main unit is synchronously reversely rotated 90 degrees, and is expanded to 180 degrees. Similarly, when one of the components of the electronic device is folded 180 degrees, the two have been folded together into 360 degrees of each other, which becomes a state of use such as a tablet computer.
